                                  INTRODUCTION

     ALL CAPITALIZED TERMS IN THIS PROSPECTUS ARE DEFINED IN THE GLOSSARY AT
                                    THE END.

GENERAL

         The mortgage pass-through certificates or mortgage-backed notes offered
by this prospectus and the prospectus supplement will be offered from time to
time in series.

         Each series of certificates will represent in the aggregate the entire
beneficial ownership interest in, and each series of notes will represent
indebtedness of, a trust fund to be established by the depositor. Each trust
fund will consist primarily of a mortgage pool of mortgage loans or interests
therein, which may include mortgage securities, acquired by the depositor from
one or more affiliated or unaffiliated sellers. See "The Depositor" and "The
Mortgage Pools." The mortgage loans may include sub-prime mortgage loans. The
trust fund assets may only include, if applicable, the mortgage loans,
reinvestment income, reserve funds, cash accounts and various forms of credit
enhancement as described in this prospectus and will be held in trust for the
benefit of the related securityholders pursuant to: (1) with respect to each
series of certificates, a pooling and servicing agreement or other agreement, or
(2) with respect to each series of notes, an indenture, in each case as more
fully described in this prospectus and in the related prospectus supplement.
Information regarding the offered securities of a series, and the general
characteristics of the mortgage loans and other trust fund assets in the related
trust fund, will be set forth in the related prospectus supplement.

         Each series of securities will include one or more classes. Each class
of securities of any series will represent the right, which right may be senior
or subordinate to the rights of one or more of the other classes of the
securities, to receive a specified portion of payments of principal or interest
or both on the mortgage loans and the other trust fund assets in the related
trust fund in the manner described in this prospectus under "Description of the
Securities" and in the related prospectus supplement. A series may include one
or more classes of securities entitled to principal distributions, with
disproportionate, nominal or no interest distributions, or to interest
distributions, with disproportionate, nominal or no principal distributions. A
series may include two or more classes of securities which differ as to the
timing, sequential order, priority of payment, pass-through rate or amount of
distributions of principal or interest or both.

         The depositor's only obligations with respect to a series of securities
will be pursuant to representations and warranties made by the depositor, except
as provided in the related prospectus supplement. The master servicer for any
series of securities will be named in the related prospectus supplement. The
principal obligations of the master servicer will be pursuant to its contractual
servicing obligations, which include its limited obligation to make advances in
the event of delinquencies in payments on the related mortgage loans. See
"Description of the Securities."

         If so specified in the related prospectus supplement, the trust fund
for a series of securities may include any one or any combination of a financial
guaranty insurance policy, mortgage pool insurance policy, letter of credit,
special hazard insurance policy, reserve fund or currency or interest rate
exchange agreements. In addition to or in lieu of the foregoing, credit


                                     - 3 -


enhancement may be provided by means of subordination of one or more classes of
securities or by overcollateralization. See "Description of Credit Enhancement."

         The rate of payment of principal of each class of securities entitled
to a portion of principal payments on the mortgage loans in the related mortgage
pool and the trust fund assets will depend on the priority of payment of the
class and the rate and timing of principal payments on the mortgage loans and
other trust fund assets, including by reason of prepayments, defaults,
liquidations and repurchases of mortgage loans. A rate of principal payments
lower or faster than that anticipated may affect the yield on a class of
securities in the manner described in this prospectus and in the related
prospectus supplement. See "Yield Considerations."

         With respect to each series of certificates, one or more separate
elections may be made to treat the related trust fund or a designated portion
thereof as a REMIC for federal income tax purposes. If applicable, the
prospectus supplement for a series of certificates will specify which class or
classes of the related series of certificates will be considered to be regular
interests in the related REMIC and which class of certificates or other
interests will be designated as the residual interest in the related REMIC. See
"Federal Income Tax Consequences" in this prospectus.

         The offered securities may be offered through one or more different
methods, including offerings through underwriters, as more fully described under
"Methods of Distribution" and in the related prospectus supplement.

         There will be no secondary market for the offered securities of any
series prior to the offering thereof. There can be no assurance that a secondary
market for any of the offered securities will develop or, if it does develop,
that it will continue. The offered securities will not be listed on any
securities exchange.

                               THE MORTGAGE POOLS

GENERAL

         Each mortgage pool will consist primarily of mortgage loans. The
mortgage loans may consist of single family loans, multifamily loans, commercial
loans, mixed-use loans and Contracts, each as described below.

         The single family loans will be evidenced by mortgage notes and secured
by mortgages that, in each case, create a first or junior lien on the related
mortgagor's fee or leasehold interest in the related mortgaged property. The
related mortgaged property for a single family loan may be owner-occupied or may
be a vacation, second or non-owner-occupied home.

         If specified in the related prospectus supplement relating to a series
of securities, the single family loans may include cooperative apartment loans
evidenced by a mortgage note secured by security interests in the related
mortgaged property including shares issued by cooperatives and in the related
proprietary leases or occupancy agreements granting exclusive rights to occupy
specific dwelling units in the related buildings.

                                     - 4 -


         The multifamily loans will be evidenced by mortgage notes and secured
by mortgages that create a first or junior lien on residential properties
consisting of five or more dwelling units in high-rise, mid-rise or garden
apartment structures or projects.

         The commercial loans will be evidenced by mortgage notes and secured
mortgages that create a first or junior lien on commercial properties including
office building, retail building and a variety of other commercial properties as
may be described in the related prospectus supplement.

         The mixed-use loans will be evidenced by mortgage loans and secured by
mortgages that create a first or junior lien on properties consisting of mixed
residential and commercial structures.

         The aggregate concentration by original principal balance of commercial
and mixed-use loans in any mortgage pool will be less than 10% of the original
principal balance of the mortgage pool.

         Mortgaged properties may be located in any one of the 50 states, the
District of Columbia or the Commonwealth of Puerto Rico.

         The mortgage loans will not be guaranteed or insured by the depositor
or any of its affiliates. However, if so specified in the related prospectus
supplement, the mortgage loans may be insured by the FHA or the VA. See
"Description of Primary Insurance Policies--FHA Insurance" and "--VA Insurance."

         A mortgage pool may include mortgage loans that are delinquent as of
the date the related series of securities is issued. In that case, the related
prospectus supplement will set forth, as to each mortgage loan, available
information as to the period of delinquency and any other information relevant
for a prospective purchaser to make an investment decision. No mortgage loan in
a mortgage pool shall be 90 days or more delinquent. Mortgage loans which are
more than 30 and less than 90 days delinquent included in any mortgage pool will
have delinquency data relating to them included in the related prospectus
supplement. No mortgage pool will include a concentration of mortgage loans
which is more than 30 and less than 90 days delinquent of 20% or more.

         The mortgage loans may include "sub-prime" mortgage loans. "Sub-prime"
mortgage loans will be underwritten in accordance with underwriting standards
which are less stringent than guidelines for "A" quality borrowers. Mortgagors
may have a record of outstanding judgments, prior bankruptcies and other credit
items that do not satisfy the guidelines for "A" quality borrowers. They may
have had past debts written off by past lenders.

         A mortgage pool may include mortgage loans that do not meet the
purchase requirements of Fannie Mae and Freddie Mac. These mortgage loans are
known as nonconforming loans. The mortgage loans may be nonconforming because
they exceed the maximum principal balance of mortgage loans purchased by Fannie
Mae and Freddie Mac, known as jumbo loans, because they are sub-prime mortgage
loans, or because of some other failure to meet the purchase criteria of Fannie
Mae and Freddie Mac. The related prospectus supplement will detail to what
extent the mortgage loans are nonconforming mortgage loans.

                                     - 5 -


         Each mortgage loan will be selected by the depositor for inclusion in a
mortgage pool from among those purchased by the depositor, either directly or
through its affiliates, from Unaffiliated Sellers or Affiliated Sellers. As to
each series of securities, the mortgage loans will be selected for inclusion in
the mortgage pool based on rating agency criteria, compliance with
representations and warranties, and conformity to criteria relating to the
characterization of securities for tax, ERISA, SMMEA, Form S-3 eligibility and
other legal purposes. If a mortgage pool is composed of mortgage loans acquired
by the depositor directly from Unaffiliated Sellers, the related prospectus
supplement will specify the extent of mortgage loans so acquired. The
characteristics of the mortgage loans are as described in the related prospectus
supplement. Other mortgage loans available for purchase by the depositor may
have characteristics which would make them eligible for inclusion in a mortgage
pool but were not selected for inclusion in the mortgage pool.

         The mortgage loans may be delivered to the trust fund pursuant to a
Designated Seller Transaction, concurrently with the issuance of the related
series of securities. These securities may be sold in whole or in part to the
Seller in exchange for the related mortgage loans, or may be offered under any
of the other methods described in this prospectus under "Methods of
Distribution." The related prospectus supplement for a mortgage pool composed of
mortgage loans acquired by the depositor pursuant to a Designated Seller
Transaction will generally include information, provided by the related Seller,
about the Seller, the mortgage loans and the underwriting standards applicable
to the mortgage loans.

      If specified in the related prospectus supplement, the trust fund for a
series of securities may include mortgage securities (including participations
in mortgage loans), as described in this prospectus. The mortgage securities may
have been issued previously by the depositor or an affiliate thereof, a
financial institution or other entity engaged generally in the business of
mortgage lending or a limited purpose corporation organized for the purpose of,
among other things, acquiring and depositing mortgage loans into trusts, and
selling beneficial interests in trusts. The mortgage securities will be
generally similar to securities offered under this prospectus. In any
securitization where mortgage securities are included in a trust fund, unless
the mortgage securities are exempt from registration under the Securities Act,
the offering of the mortgage securities will be registered if required in
accordance with Rule 190 under the Securities Act. As to any series of mortgage
securities, the related prospectus supplement will include a description of (1)
the mortgage securities and any related credit enhancement, and (2) the mortgage
loans underlying the mortgage securities.


                               THE MORTGAGE LOANS

         Each of the mortgage loans will be a type of mortgage loan described or
referred to below:

         o        Fixed-rate, fully-amortizing mortgage loans (which may include
                  mortgage loans converted from adjustable-rate mortgage loans
                  or otherwise modified) providing for level monthly payments of
                  principal and interest and terms at origination or
                  modification of not more than approximately 15 years;

         o        Fixed-rate, fully-amortizing mortgage loans (which may include
                  mortgage loans converted from adjustable-rate mortgage loans
                  or otherwise modified) providing for level monthly payments of
                  principal and interest and terms at origination or
                  modification of more than 15 years, but not more than
                  approximately 40 years;

         o        Fully-amortizing ARM Loans having an original or modified term
                  to maturity of not more than approximately 40 years with a
                  related mortgage rate which generally adjusts initially either
                  three months, six months or one, two, three, five, seven or
                  ten years or other intervals subsequent to the initial payment
                  date, and thereafter at either three-month, six-month,
                  one-year or other intervals (with corresponding adjustments in
                  the amount of monthly payments) over the term of the mortgage
                  loan to equal the sum of the related Note Margin and the Note
                  Index. The related prospectus supplement will set forth the
                  relevant Index and the highest, lowest and weighted average
                  Note Margin with respect to the ARM



                                     - 6 -


                  Loans in the related mortgage pool. The related prospectus
                  supplement will also indicate any periodic or lifetime
                  limitations on changes in any per annum mortgage rate at the
                  time of any adjustment. If specified in the related prospectus
                  supplement, an ARM Loan may include a provision that allows
                  the mortgagor to convert the adjustable mortgage rate to a
                  fixed rate at some point during the term of the ARM Loan
                  generally not later than six to ten years subsequent to the
                  initial payment date;

         o        Negatively-amortizing ARM Loans having original or modified
                  terms to maturity of not more than approximately 40 years with
                  mortgage rates which generally adjust initially on the payment
                  date referred to in the related prospectus supplement, and on
                  each of specified periodic payment dates thereafter, to equal
                  the sum of the Note Margin and the Index. The scheduled
                  monthly payment will be adjusted as and when described in the
                  related prospectus supplement to an amount that would fully
                  amortize the mortgage loan over its remaining term on a level
                  debt service basis; provided that increases in the scheduled
                  monthly payment may be subject to limitations as specified in
                  the related prospectus supplement. Any Deferred Interest will
                  be added to the principal balance of the mortgage loan;

         o        Fixed-rate, graduated payment mortgage loans having original
                  or modified terms to maturity of not more than approximately
                  15 years with monthly payments during the first year
                  calculated on the basis of an assumed interest rate which is a
                  specified percentage below the mortgage rate on the mortgage
                  loan. Monthly payments on these mortgage loans increase at the
                  beginning of the second year by a specified percentage of the
                  monthly payment during the preceding year and each year
                  thereafter to the extent necessary to amortize the mortgage
                  loan over the remainder of its approximately 15-year term.
                  Deferred Interest, if any, will be added to the principal
                  balance of these mortgage loans;

         o        Fixed-rate, graduated payment mortgage loans having original
                  or modified terms to maturity of not more than approximately
                  40 years with monthly payments during the first year
                  calculated on the basis of an assumed interest rate which is a
                  specified percentage below the mortgage rate. The monthly
                  payments on these mortgage loans increase at the beginning of
                  the second year by a specified percentage of the monthly
                  payment during the preceding year and each year thereafter to
                  the extent necessary to fully amortize the mortgage loan
                  within its approximately 25- or 30-year term. Deferred
                  Interest, if any, will be added to the principal balance of
                  these mortgage loans;

         o        Balloon loans having payment terms similar to those described
                  in one of the preceding paragraphs, calculated on the basis of
                  an assumed amortization term, but providing for a balloon
                  payment of all outstanding principal and interest to be made
                  at the end of a specified term that is shorter than the
                  assumed amortization term; or

                                     - 7 -


         o        Mortgage loans that provide for a line of credit pursuant to
                  which amounts may be advanced to the borrower from time to
                  time.

The mortgage pool may contain mortgage loans secured by junior liens, and the
related senior liens may not be included in the mortgage pool. The primary risk
to holders of mortgage loans secured by junior liens is the possibility that
adequate funds will not be received in connection with a foreclosure of the
related senior liens to satisfy fully both the senior liens and the mortgage
loan. In the event that a holder of a senior lien forecloses on a mortgaged
property, the proceeds of the foreclosure or similar sale will be applied first
to the payment of court costs and fees in connection with the foreclosure,
second to real estate taxes, third in satisfaction of all principal, interest,
prepayment or acceleration penalties, if any, and any other sums due and owing
to the holder of the senior liens. The claims of the holders of the senior liens
will be satisfied in full out of proceeds of the liquidation of the related
mortgaged property, if the proceeds are sufficient, before the trust fund as
holder of the junior lien receives any payments in respect of the mortgage loan.
If the master servicer were to foreclose on a mortgage loan secured by a junior
lien, it would do so subject to any related senior liens. In order for the debt
related to the mortgage loan to be paid in full at the sale, a bidder at the
foreclosure sale of the mortgage loan would have to bid an amount sufficient to
pay off all sums due under the mortgage loan and the senior liens or purchase
the mortgaged property subject to the senior liens. In the event that the
proceeds from a foreclosure or similar sale of the related mortgaged property
are insufficient to satisfy all senior liens and the mortgage loan in the
aggregate, the trust fund, as the holder of the junior lien, and, accordingly,
holders of one or more classes of the securities of the related series bear (1)
the risk of delay in distributions while a deficiency judgment against the
borrower is sought and (2) the risk of loss if the deficiency judgment is not
realized upon. Moreover, deficiency judgments may not be available in some
jurisdictions or the mortgage loan may be nonrecourse. In addition, a junior
mortgagee may not foreclose on the property securing a junior mortgage unless it
forecloses subject to the senior mortgages.

         A mortgage loan may contain a prohibition on prepayment or lock-out
period or require payment of a prepayment penalty. A multifamily, commercial or
mixed-use loan may also contain a provision that entitles the lender to a share
of profits realized from the operation or disposition of the related mortgaged
property. If the holders of any class or classes of offered securities of a
series will be entitled to all or a portion of this type of equity
participation, the related prospectus supplement will describe the equity
participation and the method or methods by which distributions in respect
thereof will be made to such holders.

         The mortgage loans may be "equity refinance" mortgage loans, as to
which a portion of the proceeds are used to refinance an existing mortgage loan,
and the remaining proceeds may be retained by the mortgagor or used for purposes
unrelated to the mortgaged property. Alternatively, the mortgage loans may be
"rate and term refinance" mortgage loans, as to which substantially all of the
proceeds (net of related costs incurred by the mortgagor) are used to refinance
an existing mortgage loan or loans (which may include a junior lien) primarily
in order to change the interest rate or other terms thereof. The mortgage loans
may be mortgage loans which have been consolidated and/or have had various terms
changed, mortgage loans which have been converted from adjustable rate mortgage
loans to fixed rate mortgage loans, or construction loans which have been
converted to permanent mortgage loans. In addition, a mortgaged property may be
subject to secondary financing at the time of origination



                                     - 8 -


of the mortgage loan or thereafter. In addition, some or all of the single
family loans secured by junior liens may be High LTV Loans.

         A mortgage pool may contain convertible ARM Loans which allow the
mortgagors to convert the adjustable rates on these mortgage loans to a fixed
rate at some point during the life of these mortgage loans, generally not later
than six to ten years subsequent to the date of origination, depending upon the
length of the initial adjustment period. If specified in the related prospectus
supplement, upon any conversion, the depositor, the related master servicer, the
applicable Seller or a third party will purchase the converted mortgage loan as
and to the extent set forth in the related prospectus supplement. Alternatively,
if specified in the related prospectus supplement, the depositor, or the related
master servicer (or another specified party) may agree to act as remarketing
agent with respect to the converted mortgage loans and, in this capacity, to use
its best efforts to arrange for the sale of converted mortgage loans under
specified conditions. Upon the failure of any party so obligated to purchase any
converted mortgage loan, the inability of any remarketing agent to arrange for
the sale of the converted mortgage loan and the unwillingness of the remarketing
agent to exercise any election to purchase the converted mortgage loan for its
own account, the related mortgage pool will thereafter include both fixed rate
and adjustable rate mortgage loans.

         If provided for in the related prospectus supplement, the mortgage
loans may include buydown mortgage loans. Under the terms of a buydown mortgage
loan, the monthly payments made by the mortgagor during the early years of the
mortgage loan will be less than the scheduled monthly payments on the mortgage
loan. The resulting difference will be made up from:

         o        funds contributed by the seller of the mortgaged property or
                  another source and placed in a custodial account,

         o        if funds contributed by the seller are contributed on a
                  present value basis, investment earnings on these funds or

         o        additional funds to be contributed over time by the
                  mortgagor's employer or another source.

See "Description of the Securities--Payments on Mortgage Loans; Deposits to
Certificate Account."

         Generally, the mortgagor under each buydown mortgage loan will be
qualified at the applicable lower monthly payment. Accordingly, the repayment of
a buydown mortgage loan is dependent on the ability of the mortgagor to make
larger level monthly payments after the Buydown Funds have been depleted and,
for some buydown mortgage loans, during the Buydown Period.

         The prospectus supplement for each series of securities will contain
information as to the type of mortgage loans that will be included in the
related mortgage pool. Each prospectus supplement applicable to a series of
securities will include information, generally as of the cut-off date and to the
extent then available to the depositor, on an approximate basis, as to the
following:

                                     - 9 -


         o        the aggregate principal balance of the mortgage loans,

         o        the type of property securing the mortgage loans,

         o        the original or modified terms to maturity of the mortgage
                  loans,

         o        the range of principal balances of the mortgage loans at
                  origination or modification,

         o        the earliest origination or modification date and latest
                  maturity date of the mortgage loans,

         o        the loan-to-value ratios of the mortgage loans,

         o        the mortgage rate or range of mortgage rates borne by the
                  mortgage loans,

         o        if any of the mortgage loans are ARM Loans, the applicable
                  Index, the range of Note Margins and the weighted average Note
                  Margin,

         o        the geographical distribution of the mortgage loans,

         o        the number of buydown mortgage loans, if applicable, and

         o        the percent of ARM Loans which are convertible to fixed-rate
                  mortgage loans, if applicable.

A Current Report on Form 8-K will be sent, upon request, to holders of the
related series of securities and will be filed, together with the related
pooling and servicing agreement, with respect to each series of certificates, or
the related servicing agreement, owner trust agreement and indenture, with
respect to each series of notes, with the Commission after the initial issuance
of the securities. In the event that mortgage loans are added to or deleted from
the trust fund after the date of the related prospectus supplement but on or
before the date of issuance of the securities if any material pool
characteristic differs by 5% or more from the description in the prospectus
supplement, revised disclosure will be provided either in a supplement or in a
Current Report on Form 8-K.

         The depositor will cause the mortgage loans constituting each mortgage
pool, or mortgage securities evidencing interests therein, to be assigned,
without recourse, to the trustee named in the related prospectus supplement, for
the benefit of the holders of all of the securities of a series. Except to the
extent that servicing of any mortgage loan is to be transferred to a special
servicer, the master servicer named in the related prospectus supplement will
service the mortgage loans, directly or through subservicers, pursuant to a
pooling and servicing agreement, with respect to each series of certificates, or
a servicing agreement, with respect to each series of notes, and will receive a
fee for these services. See "Servicing of Mortgage Loans--Description of the
Securities" and "The Agreements." With respect to those mortgage loans serviced
by the master servicer through a subservicer, the master servicer will remain
liable for its servicing obligations under the related pooling and servicing
agreement or servicing agreement as if the master servicer alone were servicing
the mortgage loans. The master servicer's obligations with respect to the
mortgage



                                     - 10 -


loans will consist principally of its contractual servicing obligations
under the related pooling and servicing agreement or servicing agreement
(including its obligation to enforce the purchase and other obligations of
subservicers and Sellers, as more fully described in this prospectus under
"--Representations by Sellers" in this prospectus, "Servicing of Mortgage
Loans--Subservicers," and "Description of the Securities--Assignment of Trust
Fund Assets," and, if and to the extent set forth in the related prospectus
supplement, its obligation to make cash advances in the event of delinquencies
in payments on or with respect to the mortgage loans as described in this
prospectus under "Description of the Securities -- Advances") or pursuant to the
terms of any mortgage securities.

UNDERWRITING STANDARDS

         Mortgage loans to be included in a mortgage pool will have been
purchased by the depositor, either directly or indirectly from Sellers. The
mortgage loans, as well as mortgage loans underlying mortgage securities, will
have been originated in accordance with underwriting standards acceptable to the
depositor and generally described below. Any mortgage loan not directly
underwritten by the depositor or its affiliates will be reunderwritten by the
depositor or its affiliates, except in the case of a Designated Seller's
Transaction, in which case each mortgage loan will be underwritten by the Seller
or an affiliate thereof. The reunderwriting standards of the depositor or its
affiliates for these mortgage loans generally will be in accordance with the
same standards as those for mortgage loans directly underwritten, with any
variations described in the related prospectus supplement.

         The underwriting standards to be used in originating the mortgage loans
are primarily intended to assess the creditworthiness of the mortgagor, the
value of the mortgaged property and the adequacy of the property as collateral
for the mortgage loan.

         The mortgage loans will be originated under "full/alternative", "stated
income/verified assets", "stated income/stated assets", "no documentation" or
"no ratio" programs. The "full/alternative" documentation programs generally
verify income and assets in accordance with Fannie Mae/Freddie Mac automated
underwriting requirements. The stated income/verified assets, stated
income/stated assets, no documentation or no ratio programs generally require
less documentation and verification than do full documentation programs which
generally require standard Fannie Mae/Freddie Mac approved forms for
verification of income/employment, assets and certain payment histories.
Generally, under both "full/alternative" documentation programs, at least one
month of income documentation is provided. This documentation is also required
to include year-to-date income or prior year income in case the former is not
sufficient to establish consistent income. Generally under a "stated income
verified assets" program no verification of a mortgagor's income is undertaken
by the origination however, verification of the mortgagor's assets is obtained.
Under a "stated income/stated assets" program, no verification of either a
mortgagor's income or a mortgagor's assets is undertaken by the originator
although both income and assets are stated on the loan application and a
"reasonableness test" is applied. Generally, under a "no documentation" program,
the mortgagor is not required to state his or her income or assets and
therefore, no verification of such mortgagor's income or assets is undertaken by
the originator. The underwriting for such mortgage loans may be based primarily
or entirely on the estimated value of the mortgaged property and the LTV ratio
at origination as well as on the payment history and credit score. Generally,
under a "no ratio" program, the



                                     - 11 -


mortgagor is not required to disclose their income although the nature of
employment is disclosed. Additionally, on a "no ratio" program, assets are
verified.

         The primary considerations in underwriting a mortgage loan are the
mortgagor's employment stability and whether the mortgagor has sufficient
monthly income available (1) to meet the mortgagor's monthly obligations on the
proposed mortgage loan (generally determined on the basis of the monthly
payments due in the year of origination) and other expenses related to the home
(including property taxes and hazard insurance) and (2) to meet monthly housing
expenses and other financial obligations and monthly living expenses. However,
the loan-to-value ratio of the mortgage loan is another critical factor. In
addition, a mortgagor's credit history and repayment ability, as well as the
type and use of the mortgaged property, are also considerations.

         High LTV Loans are underwritten with an emphasis on the
creditworthiness of the related mortgagor. High LTV Loans are underwritten with
a limited expectation of recovering any amounts from the foreclosure of the
related mortgaged property.

         In the case of the multifamily loans, commercial loans or mixed-use
loans, lenders typically look to the debt service coverage ratio of a loan as an
important measure of the risk of default on that loan. Unless otherwise defined
in the related prospectus supplement, the debt service coverage ratio of a
multifamily loan or commercial loan at any given time is the ratio of (1) the
net operating income of the related mortgaged property for a twelve-month period
which is to (2) the annualized scheduled payments on the mortgage loan and on
any other loan that is secured by a lien on the mortgaged property prior to the
lien of the related mortgage. The total operating revenues derived from a
multifamily, commercial or mixed-use property, as applicable, during that
period, minus the total operating expenses incurred in respect of that property
during that period other than (a) non-cash items such as depreciation and
amortization, (b) capital expenditures and (c) debt service on loans (including
the related mortgage loan) secured by liens on that property. The net operating
income of a multifamily, commercial or mixed-use property, as applicable, will
fluctuate over time and may or may not be sufficient to cover debt service on
the related mortgage loan at any given time. As the primary source of the
operating revenues of a multifamily, commercial or mixed-use property, as
applicable, rental income (and maintenance payments from tenant-stockholders of
a cooperatively owned multifamily property) may be affected by the condition of
the applicable real estate market and/or area economy. Increases in operating
expenses due to the general economic climate or economic conditions in a
locality or industry segment, such as increases in interest rates, real estate
tax rates, energy costs, labor costs and other operating expenses, and/or to
changes in governmental rules, regulations and fiscal policies, may also affect
the risk of default on a multifamily, commercial or mixed-use loan. Lenders also
look to the loan-to-value ratio of a multifamily, commercial or mixed-use loan
as a measure of risk of loss if a property must be liquidated following a
default.

         Each prospective mortgagor will generally complete a mortgage loan
application that includes information on the applicant's liabilities, income,
credit history, employment history and personal information. One or more credit
reports on each applicant from national credit reporting companies generally
will be required. The report typically contains information relating to credit
history with local and national merchants and lenders, installment debt payments
and any record of defaults, bankruptcies, repossessions, or judgments. In the
case of a



                                     - 12 -


multifamily loan, commercial loan or mixed-use loan, the mortgagor
will also be required to provide certain information regarding the related
mortgaged property, including a current rent roll and operating income
statements (which may be pro forma and unaudited). In addition, the originator
will generally also consider the location of the mortgaged property, the
availability of competitive lease space and rental income of comparable
properties in the relevant market area, the overall economy and demographic
features of the geographic area and the mortgagor's prior experience in owning
and operating properties similar to the multifamily properties or commercial
properties, as the case may be.

         Mortgaged properties generally will be appraised by licensed
appraisers. The appraiser will generally address neighborhood conditions, site
and zoning status and condition and valuation of improvements. In the case of
mortgaged properties secured by single family loans, the appraisal report will
generally include a reproduction cost analysis (when appropriate) based on the
current cost of constructing a similar home and a market value analysis based on
recent sales of comparable homes in the area. With respect to multifamily
properties, commercial properties and mixed-use properties, the appraisal must
specify whether an income analysis, a market analysis or a cost analysis was
used. An appraisal employing the income approach to value analyzes a property's
projected net cash flow, capitalization and other operational information in
determining the property's value. The market approach to value analyzes the
prices paid for the purchase of similar properties in the property's area, with
adjustments made for variations between those other properties and the property
being appraised. The cost approach to value requires the appraiser to make an
estimate of land value and then determine the current cost of reproducing the
improvements less any accrued depreciation. In any case, the value of the
property being financed, as indicated by the appraisal, must support, and
support in the future, the outstanding loan balance. All appraisals are required
to be on forms acceptable to Fannie Mae or Freddie Mac.

         Notwithstanding the foregoing, loan-to-value ratios will not
necessarily constitute an accurate measure of the risk of liquidation loss in a
pool of mortgage loans. For example, the value of a mortgaged property as of the
date of initial issuance of the related series of securities may be less than
the Value determined at loan origination, and will likely continue to fluctuate
from time to time based upon changes in economic conditions and the real estate
market. Mortgage loans which are subject to negative amortization will have
loan-to-value ratios which will increase after origination as a result of
negative amortization. Also, even when current, an appraisal is not necessarily
a reliable estimate of value for a multifamily property or commercial property.
As stated above, appraised values of multifamily, commercial and mixed-use
properties are generally based on the market analysis, the cost analysis, the
income analysis, or upon a selection from or interpolation of the values derived
from those approaches. Each of these appraisal methods can present analytical
difficulties. It is often difficult to find truly comparable properties that
have recently been sold; the replacement cost of a property may have little to
do with its current market value; and income capitalization is inherently based
on inexact projections of income and expenses and the selection of an
appropriate capitalization rate. Where more than one of these appraisal methods
are used and provide significantly different results, an accurate determination
of value and, correspondingly, a reliable analysis of default and loss risks, is
even more difficult.

                                     - 13 -


         If so specified in the related prospectus supplement, the underwriting
of a multifamily loan, commercial loan or mixed-use loan may also include
environmental testing. Under the laws of some states, contamination of real
property may give rise to a lien on the property to assure the costs of cleanup.
In several states, this type of lien has priority over an existing mortgage lien
on that property. In addition, under the laws of some states and under the
federal Comprehensive Environmental Response, Compensation and Liability Act of
1980, a lender may be liable, as an "owner" or "operator", for costs of
addressing releases or threatened releases of hazardous substances at a
property, if agents or employees of the lender have become sufficiently involved
in the operations of the borrower, regardless of whether or not the
environmental damage or threat was caused by the borrower or a prior owner. A
lender also risks such liability on foreclosure of the mortgage as described
under "Legal Aspects of Mortgage Loans--Environmental Legislation" in this
prospectus.

         With respect to any FHA loan or VA loans the mortgage loan Seller will
be required to represent that it has complied with the applicable underwriting
policies of the FHA or VA, respectively. See "Description of Primary Insurance
Policies--FHA Insurance" and "--VA Insurance" in this prospectus.

FICO SCORES

         The FICO Score is a statistical ranking of likely future credit
performance developed by Fair, Isaac & Company ("Fair, Isaac") and the three
national credit repositories-Equifax, Trans Union and First American (formerly
Experian which was formerly TRW). The FICO Scores available from the three
national credit repositories are calculated by the assignment of weightings to
the most predictive data collected by the credit repositories and range from the
300's to the 900's. Although the FICO Scores are based solely on the information
at the particular credit repository, such FICO Scores have been calibrated to
indicate the same level of credit risk regardless of which credit repository is
used. The FICO Scores are used along with, but not limited to, mortgage payment
history and seasoning on bankruptcy and/or foreclosure, and is not a substitute
for the underwriter's judgment.

QUALIFICATIONS OF ORIGINATORS AND SELLERS

         Each mortgage loan generally will be originated, directly or through
mortgage brokers and correspondents, by a savings and loan association, savings
bank, commercial bank, credit union, insurance company, or similar institution
which is supervised and examined by a federal or state authority, or by a
mortgagee approved by, unless otherwise provided in the prospectus supplement,
the Secretary of Housing and Urban Development pursuant to sections 203 and 211
of the Housing Act.

REPRESENTATIONS BY SELLERS

         Each Seller will have made representations and warranties in respect of
the mortgage loans and/or mortgage securities sold by the Seller and evidenced
by a series of securities. In the case of mortgage loans,


                                     - 14 -


representations and warranties will generally include, among other things, that
as to each mortgage loan:

         o        any required hazard and primary mortgage insurance policies
                  were effective at the origination of the mortgage loan, and
                  each the policy remained in effect on the date of purchase of
                  the mortgage loan from the Seller by or on behalf of the
                  depositor;

         o        with respect to each mortgage loan other than a Contract or a
                  cooperative mortgage loan, either (A) a title insurance policy
                  insuring (subject only to permissible title insurance
                  exceptions) the lien status of the mortgage was effective at
                  the origination of the mortgage loan and the policy remained
                  in effect on the date of purchase of the mortgage loan from
                  the Seller by or on behalf of the depositor or (B) if the
                  mortgaged property securing the mortgage loan is located in an
                  area where these policies are generally not available, there
                  is in the related mortgage file an attorney's certificate of
                  title indicating (subject to permissible exceptions set forth
                  therein) the lien status of the mortgage;

         o        the Seller has good title to the mortgage loan and the
                  mortgage loan was subject to no offsets, defenses or
                  counterclaims except as may be provided under the Relief Act
                  and except to the extent that any buydown agreement exists for
                  a buydown mortgage loan;

         o        there are no mechanics' liens or claims for work, labor or
                  material affecting the related mortgaged property which are,
                  or may be a lien prior to, or equal with, the lien of the
                  related mortgage (subject only to permissible title insurance
                  exceptions);

         o        the related mortgaged property is free from damage and in good
                  repair;

         o        there are no delinquent tax or assessment liens against the
                  related mortgaged property;

         o        the mortgage loan is not more than 90 days delinquent as to
                  any scheduled payment of principal and/or interest;

         o        if a Primary Insurance Policy is required with respect to the
                  mortgage loan, the mortgage loan is the subject of the policy;
                  and

         o        the mortgage loan was made in compliance with, and is
                  enforceable under, all applicable local, state and federal
                  laws in all material respects.

If the mortgage loans include cooperative mortgage loans, representations and
warranties with respect to title insurance or hazard insurance may not be given.
Generally, the cooperative itself is responsible for the maintenance of hazard
insurance for property owned by the cooperative, and the borrowers
(tenant-stockholders) of the cooperative do not maintain hazard insurance on
their individual dwelling units. In the case of mortgage securities,
representations and warranties will generally include, among other things, that
as to each mortgage security: (1) the mortgage security is validly issued and
outstanding and entitled to the benefits of the agreement pursuant to which it
was issued; and (2) the Seller has good title to the mortgage security. In the
event of a breach of a Seller's representation or warranty that materially
adversely affects the interests of the securityholders in a mortgage loan or
mortgage security, the


                                     - 15 -


related Seller will be obligated to cure the breach or repurchase or, if
permitted, replace the mortgage loan as described below. However, there can be
no assurance that a Seller will honor its obligation to repurchase or, if
permitted, replace any mortgage loan or mortgage security as to which a breach
of a representation or warranty arises.

         All of the representations and warranties of a Seller in respect of a
mortgage loan or mortgage security will have been made as of the date on which
the mortgage loan or mortgage security was purchased from the Seller by or on
behalf of the depositor. As a result, the date as of which the representations
and warranties were made may be a date prior to the date of initial issuance of
the related series of securities or, in the case of a Designated Seller
Transaction, will be the date of closing of the related sale by the applicable
Seller. A substantial period of time may have elapsed between the date as of
which there presentations and warranties were made and the later date of initial
issuance of the related series of securities. Accordingly, the Seller's purchase
obligation (or, if specified in the related prospectus supplement, limited
replacement option) described below will not arise if, during the period
commencing on the date of sale of a mortgage loan or mortgage security or
mortgage security by the Seller, an event occurs that would have given rise to a
purchase obligation had the event occurred prior to sale of the affected
mortgage loan or mortgage security, as the case may be. The only representations
and warranties to be made for the benefit of holders of securities in respect of
any related mortgage loan or mortgage security relating to the period commencing
on the date of sale of the mortgage loan or mortgage security by the Seller to
or on behalf of the depositor will be the limited representations of the
depositor and the master servicer described under "Description of the
Securities--Assignment of Trust Fund Assets" below.

         The depositor will assign to the trustee for the benefit of the holders
of the related series of securities all of its right, title and interest in each
purchase agreement by which it purchased a mortgage loan from a Seller insofar
as the purchase agreement relates to the representations and warranties made by
the Seller in respect of the mortgage loan and any remedies provided for with
respect to any breach of representations and warranties with respect to the
mortgage loan. If a Seller cannot cure a breach of any representation or
warranty made by it in respect of a mortgage loan which materially and adversely
affects the interests of the securityholders therein within a specified period
after having discovered or received notice of a breach, then, the Seller will be
obligated to purchase the mortgage loan at a purchase price set forth in the
related pooling and servicing agreement or other agreement which purchase price
generally will be equal to the principal balance thereof as of the date of
purchase plus accrued and unpaid interest through or about the date of purchase
at the related mortgage rate or pass-through rate, as applicable (net of any
portion of this interest payable to the Seller in respect of master servicing
compensation, special servicing compensation or subservicing compensation, as
applicable, and any interest retained by the depositor).

         As to any mortgage loan required to be purchased by a Seller as
provided above, rather than repurchase the mortgage loan, the Seller, if so
specified in the related prospectus supplement, will be entitled, at its sole
option, to remove the Deleted Mortgage Loan from the trust fund and substitute
in its place a Qualified Substitute Mortgage Loan; however, with respect to a
series of certificates for which no REMIC election is to be made, the
substitution must be effected within 120 days of the date of the initial
issuance of the related series of certificates.



                                     - 16 -


With respect to a trust fund for which a REMIC election is to be made, the
substitution of a defective mortgage loan must be effected within two years of
the date of the initial issuance of the related series of certificates, and may
not be made if the substitution would cause the trust fund, or any portion
thereof, to fail to qualify as a REMIC or result in a Prohibited Transaction Tax
under the Code. Any Qualified Substitute Mortgage Loan generally will, on the
date of substitution:

         o        have an outstanding principal balance, after deduction of the
                  principal portion of the monthly payment due in the month of
                  substitution, not in excess of the outstanding principal
                  balance of the Deleted Mortgage Loan (the amount of any
                  shortfall to be deposited in the Certificate Account by the
                  related Seller or the master servicer in the month of
                  substitution for distribution to the securityholders),

         o        have a mortgage rate and a Net Mortgage Rate not less than
                  (and not more than one percentage point greater than) the
                  mortgage rate and Net Mortgage Rate, respectively, of the
                  Deleted Mortgage Loan as of the date of substitution,

         o        have a loan-to-value ratio at the time of substitution no
                  higher than that of the Deleted Mortgage Loan at the time of
                  substitution,

         o        have a remaining term to maturity not greater than (and not
                  more than one year less than) that of the Deleted Mortgage
                  Loan and

         o        comply with all of the representations and warranties made by
                  the Seller as of the date of substitution.

The related mortgage loan purchase agreement may include additional requirements
relating to ARM Loans or other specific types of mortgage loans, or additional
provisions relating to meeting the foregoing requirements on an aggregate basis
where a number of substitutions occur contemporaneously.

         The master servicer will be required under the applicable pooling and
servicing agreement or servicing agreement to use reasonable efforts to enforce
this purchase or substitution obligation for the benefit of the trustee and the
securityholders, following those practices it would employ in its good faith
business judgment and which are normal and usual in its general mortgage
servicing activities; provided, however, that this purchase or substitution
obligation will not become an obligation of the master servicer in the event the
applicable Seller fails to honor the obligation. In instances where a Seller is
unable, or disputes its obligation, to purchase affected mortgage loans and/or
mortgage securities, the master servicer, employing the standards set forth in
the preceding sentence, may negotiate and enter into one or more settlement
agreements with the related Seller that could provide for the purchase of only a
portion of the affected mortgage loans and/or mortgage securities. Any
settlement could lead to losses on the mortgage loans and/or mortgage securities
which would be borne by the related securities. In accordance with the above
described practices, the master servicer will not be required to enforce any
purchase obligation of a Seller arising from any misrepresentation by the
Seller, if the master servicer determines in the reasonable exercise of its
business judgment


                                     - 17 -


that the matters related to the misrepresentation did not directly cause or are
not likely to directly cause a loss on the related mortgage loan or mortgage
security. If the Seller fails to repurchase and no breach of any other party's
representations has occurred, the Seller's purchase obligation will not become
an obligation of the depositor or any other party. In the case of a Designated
Seller Transaction where the Seller fails to repurchase a mortgage loan or
mortgage security and neither the depositor nor any other entity has assumed the
representations and warranties, the repurchase obligation of the Seller will not
become an obligation of the depositor or any other party. The foregoing
obligations will constitute the sole remedies available to securityholders or
the trustee for a breach of any representation by a Seller or for any other
event giving rise to the obligations as described above.

         Neither the depositor nor the master servicer will be obligated to
purchase a mortgage loan if a Seller defaults on its obligation to do so, and no
assurance can be given that the Sellers will carryout their purchase
obligations. A default by a Seller is not a default by the depositor or by the
master servicer. However, to the extent that a breach of there presentations and
warranties of a Seller also constitutes a breach of a representation made by the
depositor or the master servicer, as described below under "Description of the
Securities--Assignment of Trust Fund Assets," the depositor or the master
servicer may have a purchase or substitution obligation. Any mortgage loan not
so purchased or substituted for shall remain in the related trust fund and any
losses related thereto shall be allocated to the related credit enhancement, to
the extent available, and otherwise to one or more classes of the related series
of securities.

         If a person other than a Seller makes the representations and
warranties referred to in the first paragraph of this "--Representations by
Sellers" section, or a person other than a Seller is responsible for
repurchasing or replacing any mortgage loan for a breach of those
representations and warranties, the identity of that person will be specified in
the related prospectus supplement.

                            STATIC POOL INFORMATION

         For each mortgage pool discussed above, the issuing entity will provide
static pool information with respect to the experience of the sponsor, or other
appropriate entity, in securitizing asset pools of the same type to the extent
material, if available.

         With respect to each series of securities, the information referred to
in this section will be provided through an internet web site at the address
disclosed in the related prospectus supplement.

                           SERVICING OF MORTGAGE LOANS

GENERAL

         The mortgage loans and mortgage securities included in each mortgage
pool will be serviced and administered pursuant to either a pooling and
servicing agreement or a servicing agreement. Forms of pooling and servicing
agreements and a form of servicing agreement have been filed as an exhibit to
the registration statement of which this prospectus is a part. However, the
provisions of each pooling and servicing agreement or servicing agreement will
vary depending upon the nature of



                                     - 18 -


the related mortgage pool. The following summaries describe the material
servicing-related provisions that may appear in a pooling and servicing
agreement or servicing agreement for a mortgage pool that includes mortgage
loans. The related prospectus supplement will describe any servicing-related
provision of its related pooling and servicing agreement or servicing agreement
that materially differs from the description thereof contained in this
prospectus. If the related mortgage pool includes mortgage securities, the
related prospectus supplement will summarize the material provisions of the
related pooling and servicing agreement and identify the responsibilities of the
parties to that pooling and servicing agreement.

         With respect to any series of securities as to which the related
mortgage pool includes mortgage securities, the servicing and administration of
the mortgage loans underlying any mortgage securities will be pursuant to the
terms of those mortgage securities. Mortgage loans underlying mortgage
securities in a mortgage pool will be serviced and administered generally in the
same manner as mortgage loans included in a mortgage pool, however, there can be
no assurance that this will be the case, particularly if the mortgage securities
are issued by an entity other than the depositor or any of its affiliates. The
related prospectus supplement will describe any material differences between the
servicing described below and the servicing of the mortgage loans underlying
mortgage securities in any mortgage pool.

THE MASTER SERVICER

         The master servicer, if any, for a series of securities will be named
in the related prospectus supplement and may be Impac Funding Corporation or
another affiliate of the depositor. The master servicer is required to maintain
a fidelity bond and errors and omissions policy with respect to its officers and
employees and other persons acting on behalf of the master servicer in
connection with its activities under a pooling and servicing agreement or a
servicing agreement.

COLLECTION AND OTHER SERVICING PROCEDURES; MORTGAGE LOAN MODIFICATIONS

         The master servicer for any mortgage pool, directly or through
subservicers, will be obligated under the pooling and servicing agreement or
servicing agreement to service and administer the mortgage loans in the mortgage
pool for the benefit of the related securityholders, in accordance with
applicable law, the terms of the pooling and servicing agreement or servicing
agreement, the mortgage loans and any instrument of credit enhancement included
in the related trust fund, and, to the extent consistent with the foregoing, the
customs and standards of prudent institutional mortgage lenders servicing
comparable mortgage loans for their own account in the jurisdictions where the
related mortgaged properties are located. Subject to the foregoing, the master
servicer will have full power and authority to do any and all things in
connection with servicing and administration that it may deem necessary and
desirable.

         As part of its servicing duties, the master servicer will be required
to make reasonable efforts to collect all payments called for under the terms
and provisions of the mortgage loans that it services. The master servicer will
be obligated to follow the same collection procedures as it would follow for
comparable mortgage loans held for its own account, so long as these procedures
are consistent with the servicing standard of and the terms of the related
pooling and servicing agreement or servicing agreement and the servicing
standard generally described in the preceding paragraph, and do not impair
recovery under any instrument of credit enhancement included in the related
trust fund. Consistent with the foregoing, the master servicer will be
permitted, in its discretion, to waive any prepayment premium, late payment
charge or other charge in connection with any mortgage loan. In any event, no
waiver of a prepayment premium, late premium charge or other charge in
connection with any mortgage loan shall affect the potential cash flow from the
pool assets.

         Under a pooling and servicing agreement or a servicing agreement, a
master servicer will be granted discretion to extend relief to mortgagors whose
payments become delinquent. In the case of single family loans and Contracts, a
master servicer may, for example, grant a period of temporary indulgence to a
mortgagor or may enter into a liquidating plan providing for repayment of
delinquent amounts within a specified period from the date of execution of the


                                     - 19 -


plan. However, the master servicer must first determine that any waiver or
extension will not impair the coverage of any related insurance policy or
materially adversely affect the security for the mortgage loan. In addition,
unless otherwise specified in the related prospectus supplement, if a material
default occurs or a payment default is reasonably foreseeable with respect to a
multifamily loan, commercial loan or mixed-use loan, the master servicer will be
permitted, subject to any specific limitations set forth in the related pooling
and servicing agreement or servicing agreement and described in the related
prospectus supplement, to modify, waive or amend any term of such mortgage loan,
including deferring payments, extending the stated maturity date or otherwise
adjusting the payment schedule, provided that the modification, waiver or
amendment (1) is reasonably likely to produce a greater recovery with respect to
that mortgage loan on a present value basis than would liquidation and (2) will
not adversely affect the coverage under any applicable instrument of credit
enhancement.

         In the case of multifamily loans, commercial loans and mixed-use loans,
a mortgagor's failure to make required mortgage loan payments may mean that
operating income is insufficient to service the mortgage debt, or may reflect
the diversion of that income from the servicing of the mortgage debt. In
addition, a mortgagor under a multifamily, commercial or mixed-use loan that is
unable to make mortgage loan payments may also be unable to make timely payment
of taxes and otherwise to maintain and insure the related mortgaged property.
Generally, the related master servicer will be required to monitor any
multifamily loan or commercial loan that is in default, evaluate whether the
causes of the default can be corrected over a reasonable period without
significant impairment of the value of the related mortgaged property, initiate
corrective action in cooperation with the mortgagor if cure is likely, inspect
the related mortgaged property and take any other actions as are consistent with
the servicing standard described above and in the pooling and servicing
agreement or servicing agreement. A significant period of time may elapse before
the master servicer is able to assess the success of any such corrective action
or the need for additional initiatives. The time within which the master
servicer can make the initial determination of appropriate action, evaluate the
success of corrective action, develop additional initiatives, institute
foreclosure proceedings and actually foreclose (or accept a deed to a mortgaged
property in lieu of foreclosure) on behalf of the securityholders of the related
series may vary considerably depending on the particular multifamily, commercial
or mixed-use loan, the mortgaged property, the mortgagor, the presence of an
acceptable party to assume that loan and the laws of the jurisdiction in which
the mortgaged property is located. If a mortgagor files a bankruptcy petition,
the master servicer may not be permitted to accelerate the maturity of the
related multifamily, commercial or mixed-use loan or to foreclose on the
mortgaged property for a considerable period of time. See "Legal Aspects of
Mortgage Loans."

         Some or all of the mortgage loans in a mortgage pool may contain a
due-on-sale clause that entitles the lender to accelerate payment of the
mortgage loan upon any sale or other transfer of the related mortgaged property
made without the lender's consent. In any case in which a mortgaged property is
being conveyed by the mortgagor, the master servicer will in general be
obligated, to the extent it has knowledge of the conveyance, to exercise its
rights to accelerate the maturity of the related mortgage loan under any
due-on-sale clause applicable thereto, but only if the exercise of these rights
is permitted by applicable law and only to the extent it would not adversely
affect or jeopardize coverage under any Primary Insurance Policy or applicable
credit enhancement arrangements. If applicable law prevents the master servicer
from enforcing a due-on-sale or due-on-encumbrance clause or if the master
servicer determines that it is



                                     - 20 -


reasonably likely that the related mortgagor would institute a legal action to
avoid enforcement of a due-on-sale or due-on-encumbrance clause, the master
servicer may enter into an assumption and modification agreement with the person
to whom the property has been or is about to be conveyed, pursuant to which this
person becomes liable under the mortgage loan subject to specified conditions.
The original mortgagor may be released from liability on a single family loan if
the master servicer shall have determined in good faith that the release will
not adversely affect the collectability of the mortgage loan. The master
servicer will determine whether to exercise any right the trustee may have under
any due-on-sale or due-on-encumbrance provision in a multifamily loan,
commercial loan or mixed-use loan in a manner consistent with the servicing
standard. The master servicer generally will be entitled to retain as additional
servicing compensation any fee collected in connection with the permitted
transfer of a mortgaged property. See "Legal Aspects of Mortgage
Loans--Enforceability of Certain Provisions." FHA loans do not contain
due-on-sale or due-on-encumbrance clauses and may be assumed by the purchaser of
the mortgaged property.

         Mortgagors may, from time to time, request partial releases of the
mortgaged properties, easements, consents to alteration or demolition and other
similar matters. The master servicer may approve a request if it has determined,
exercising its good faith business judgment in the same manner as it would if it
were the owner of the related mortgage loan, that approval will not adversely
affect the security for, or the timely and full collectability of, the related
mortgage loan. Any fee collected by the master servicer for processing these
requests will be retained by the master servicer as additional servicing
compensation.

         In the case of mortgage loans secured by junior liens on the related
mortgaged properties, the master servicer will be required to file (or cause to
be filed) of record a request for notice of any action by a superior lienholder
under the senior lien for the protection of the related trustee's interest,
where permitted by local law and whenever applicable state law does not require
that a junior lienholder be named as a party defendant in foreclosure
proceedings in order to foreclose the junior lienholder's equity of redemption.
The master servicer also will be required to notify any superior lienholder in
writing of the existence of the mortgage loan and request notification of any
action (as described below) to be taken against the mortgagor or the mortgaged
property by the superior lienholder. If the master servicer is notified that any
superior lienholder has accelerated or intends to accelerate the obligations
secured by the related senior lien, or has declared or intends to declare a
default under the mortgage or the promissory note secured thereby, or has filed
or intends to file an election to have the related mortgaged property sold or
foreclosed, then, the master servicer will be required to take, on behalf of the
related trust fund, whatever actions are necessary to protect the interests of
the related securityholders, and/or to preserve the security of the related
mortgage loan, subject to the REMIC Provisions, if applicable. The master
servicer will be required to advance the necessary funds to cure the default or
reinstate the superior lien, if the advance is in the best interests of the
related securityholders and the master servicer determines the advances are
recoverable out of payments on or proceeds of the related mortgage loan.

         The master servicer for any mortgage pool will also be required to
perform other customary functions of a servicer of comparable loans, including
maintaining escrow or impound accounts for payment of taxes, insurance premiums
and similar items, or otherwise monitoring the timely payment of those items;
adjusting mortgage rates on ARM Loans; maintaining Buydown Accounts; supervising
foreclosures and similar proceedings; managing REO properties; and maintaining


                                     - 21 -


servicing records relating to the mortgage loans in the mortgage pool. The
master servicer will be responsible for filing and settling claims in respect of
particular mortgage loans under any applicable instrument of credit enhancement.
See "Description of Credit Enhancement."

SUBSERVICERS

         A master servicer may delegate its servicing obligations in respect of
the mortgage loans serviced by it to one or more third-party subservicers, but
the master servicer will remain liable for its obligations under the related
pooling and servicing agreement or servicing agreement. The master servicer will
be solely liable for all fees owed by it to any subservicer, regardless of
whether the master servicer's compensation pursuant to the related pooling and
servicing agreement or servicing agreement is sufficient to pay the
subservicer's fees. Each subservicer will be entitled to reimbursement for some
of the expenditures which it makes, generally to the same extent as would the
master servicer for making the same expenditures. See "--Servicing and Other
Compensation and Payment of Expenses; Retained Interest" below and "Description
of the Securities--The Certificate Account."

SPECIAL SERVICERS

         If and to the extent specified in the related prospectus supplement, a
special servicer may be a party to the related pooling and servicing agreement
or servicing agreement or may be appointed by the master servicer or another
specified party to perform specified duties in respect of servicing the related
mortgage loans that would otherwise be performed by the master servicer (for
example, the workout and/or foreclosure of defaulted mortgage loans). The rights
and obligations of any special servicer will be specified in the related
prospectus supplement, and the master servicer will be liable for the
performance of a special servicer only if, and to the extent, set forth in that
prospectus supplement.

REALIZATION UPON OR SALE OF DEFAULTED MORTGAGE LOANS

         Except as described below, the master servicer will be required, in a
manner consistent with the servicing standard, to foreclose upon or otherwise
comparably convert the ownership of properties securing any mortgage loans in
the related mortgage pool that come into and continue in default and as to which
no satisfactory arrangements can be made for collection of delinquent payments.
Generally, the foreclosure process will commence no later than 90 days after
delinquency of the related mortgage loan. The master servicer will be authorized
to institute foreclosure proceedings, exercise any power of sale contained in
the related mortgage, obtain a deed in lieu of foreclosure, or otherwise acquire
title to the related mortgaged property, by operation of law or otherwise, if
the action is consistent with the servicing standard. The master servicer's
actions in this regard must be conducted, however, in a manner that will permit
recovery under any instrument of credit enhancement included in the related
trust fund. In addition, the master servicer will not be required to expend its
own funds in connection with any foreclosure or to restore any damaged property
unless it shall determine that (1) the foreclosure



                                     - 22 -


and/or restoration will increase the proceeds of liquidation of the mortgage
loan to the related securityholders after reimbursement to itself for these
expenses and (2) these expenses will be recoverable to it from related Insurance
Proceeds, Liquidation Proceeds or amounts drawn out of any fund or under any
instrument constituting credit enhancement (respecting which it shall have
priority for purposes of withdrawal from the Certificate Account in accordance
with the pooling and servicing agreement or servicing agreement).

         However, unless otherwise specified in the related prospectus
supplement, the master servicer may not acquire title to any multifamily
property or commercial property securing a mortgage loan or take any other
action that would cause the related trustee, for the benefit of securityholders
of the related series, or any other specified person to be considered to hold
title to, to be a "mortgagee-in-possession" of, or to be an "owner" or an
"operator" of such mortgaged property within the meaning of federal
environmental laws, unless the master servicer has previously determined, based
on a report prepared by a person who regularly conducts environmental audits
(which report will be an expense of the trust fund), that either:

         (1)      the mortgaged property is in compliance with applicable
                  environmental laws and regulations or, if not, that taking
                  actions as are necessary to bring the mortgaged property into
                  compliance with these laws is reasonably likely to produce a
                  greater recovery on a present value basis than not taking
                  those actions; and

         (2)      there are no circumstances or conditions present at the
                  mortgaged property that have resulted in any contamination for
                  which investigation, testing, monitoring, containment,
                  clean-up or remediation could be required under any applicable
                  environmental laws and regulations or, if those circumstances
                  or conditions are present for which any such action could be
                  required, taking those actions with respect to the mortgaged
                  property is reasonably likely to produce a greater recovery on
                  a present value basis than not taking those actions. See
                  "Legal Aspects of Mortgage Loans--Environmental Legislation."

         The master servicer will not be obligated to foreclose upon or
otherwise convert the ownership of any mortgaged property securing a single
family loan if it has received notice or has actual knowledge that the property
may be contaminated with or affected by hazardous wastes or hazardous
substances; however, environmental testing will not be required. The master
servicer will not be liable to the securityholders of the related series if,
based on its belief that no such contamination or effect exists, the master
servicer forecloses on a mortgaged property and takes title to the mortgaged
property, and thereafter the mortgaged property is determined to be so
contaminated or affected.

         With respect to a mortgage loan in default, the master servicer may
pursue foreclosure (or similar remedies) concurrently with pursuing any remedy
for a breach of a representation and warranty. However, the master servicer is
not required to continue to pursue both remedies if it determines that one
remedy is more likely than the other to result in a greater recovery. Upon the
first to occur of final liquidation (by foreclosure or otherwise) or a
repurchase or substitution pursuant to a breach of a representation and
warranty, the mortgage loan will be removed from the related trust fund if it
has not been removed previously. The master servicer may elect to treat a
defaulted mortgage loan as having been finally liquidated if a substantial
portion or all of



                                     - 23 -


the amounts expected to be received from that mortgage loan have been received.
Any additional liquidation expenses relating to the mortgage loan thereafter
incurred will be reimbursable to the master servicer (or any subservicer) from
any amounts otherwise distributable to holders of securities of the related
series, or may be offset by any subsequent recovery related to the mortgage
loan. Alternatively, for purposes of determining the amount of related
Liquidation Proceeds to be distributed to securityholders, the amount of any
Realized Loss or the amount required to be drawn under any applicable form of
credit support, the master servicer may take into account minimal amounts of
additional receipts expected to be received, as well as estimated additional
liquidation expenses expected to be incurred in connection with the defaulted
mortgage loan.

         As provided above, the master servicer may pass through less than the
full amount it expects to receive from the related mortgage loan; however, the
master servicer may only do this if the master servicer reasonably believes it
will maximize the proceeds to the securityholders in the aggregate. To the
extent the master servicer receives additional recoveries following liquidation,
the amount of the Realized Loss will be restated, and the additional recoveries
will be passed through the trust as Liquidation Proceeds. In the event the
amount of the Realized Loss is restated, the amount of overcollateralization or
the principal balance of the most subordinate class of securities in the trust
may be increased. However, the holders of any securities whose principal balance
is increased will not be reimbursed interest for the period during which the
principal balance of their securities was lower.

         With respect to a series of securities, if so provided in the related
prospectus supplement, the applicable form of credit enhancement may provide, to
the extent of coverage, that a defaulted mortgage loan will be removed from the
trust fund prior to the final liquidation thereof. In addition, a pooling and
servicing agreement or servicing agreement may grant to the master servicer, a
special servicer, a provider of credit enhancement and/or the holder or holders
of specified classes of securities of the related series a right of first
refusal to purchase from the trust fund, at a predetermined purchase price, any
mortgage loan as to which a specified number of scheduled payments are
delinquent. If the purchase price is insufficient to fully fund the entitlements
of securityholders to principal and interest, it will be specified in the
related prospectus supplement. Furthermore, a pooling and servicing agreement or
a servicing agreement may authorize the master servicer to sell any defaulted
mortgage loan if and when the master servicer determines, consistent with the
servicing standard, that the sale would produce a greater recovery to
securityholders on a present value basis than would liquidation of the related
mortgaged property.

         In the event that title to any mortgaged property is acquired by
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
will be issued to the trustee or to its nominee on behalf of securityholders of
the related series. Notwithstanding any acquisition of title and cancellation of
the related mortgage loan, the REO Mortgage Loan will be considered for most
purposes to be an outstanding mortgage loan held in the trust fund until the
mortgaged property is sold and all recoverable Liquidation Proceeds and
Insurance Proceeds have been received with respect to the defaulted mortgage
loan. For purposes of calculations of amounts distributable to securityholders
in respect of an REO Mortgage Loan, the amortization schedule in effect at the
time of any acquisition of title (before any adjustment thereto by reason of any
bankruptcy or any similar proceeding or any moratorium or similar waiver or
grace period) will be deemed to have



                                     - 24 -


continued in effect (and, in the case of an ARM Loan, the amortization schedule
will be deemed to have adjusted in accordance with any interest rate changes
occurring on any adjustment date therefor) so long as the REO Mortgage Loan is
considered to remain in the trust fund.

         If title to any mortgaged property is acquired by a trust fund as to
which a REMIC election has been made, the master servicer, on behalf of the
trust fund, will be required to sell the mortgaged property within three years
of acquisition, unless (1) the IRS grants an extension of time to sell the
property or (2) the trustee receives an opinion of independent counsel to the
effect that the holding of the property by the trust fund for more than three
years after its acquisition will not result in the imposition of a tax on the
trust fund or cause the trust fund to fail to qualify as a REMIC under the Code
at any time that any certificate is outstanding. Subject to the foregoing and
any other tax-related constraints, the master servicer generally will be
required to solicit bids for any mortgaged property so acquired in a manner as
will be reasonably likely to realize a fair price for the property. If title to
any mortgaged property is acquired by a trust fund as to which a REMIC election
has been made, the master servicer will also be required to ensure that the
mortgaged property is administered so that it constitutes "foreclosure property"
within the meaning of Section 860G(a)(8) of the Code at all times, that the sale
of the property does not result in the receipt by the trust fund of any income
from non-permitted assets as described in Section 860F(a)(2)(B) of the Code, and
that the trust fund does not derive any "net income from foreclosure property"
within the meaning of Section 860G(c)(2) of the Code with respect to the
property.

         If Liquidation Proceeds collected with respect to a defaulted mortgage
loan are less than the outstanding principal balance of the defaulted mortgage
loan plus accrued interest plus the aggregate amount of reimbursable expenses
incurred by the master servicer with respect to the mortgage loan, and the
shortfall is not covered under any applicable instrument or fund constituting
credit enhancement, the trust fund will realize a loss in the amount of the
difference. The master servicer will be entitled to reimburse itself from the
Liquidation Proceeds recovered on any defaulted mortgage loan, prior to the
distribution of Liquidation Proceeds to securityholders, amounts that represent
unpaid servicing compensation in respect of the mortgage loan, unreimbursed
servicing expenses incurred with respect to the mortgage loan and any
unreimbursed advances of delinquent payments made with respect to the mortgage
loan. If so provided in the related prospectus supplement, the applicable form
of credit enhancement may provide for reinstatement subject to specified
conditions in the event that, following the final liquidation of a mortgage loan
and a draw under the credit enhancement, subsequent recoveries are received. In
addition, if a gain results from the final liquidation of a defaulted mortgage
loan or an REO Mortgage Loan which is not required by law to be remitted to the
related mortgagor, the master servicer will be entitled to retain the gain as
additional servicing compensation unless the related prospectus supplement
provides otherwise. For a description of the master servicer's (or other
specified person's) obligations to maintain and make claims under applicable
forms of credit enhancement and insurance relating to the mortgage loans, see
"Description of Credit Enhancement" and "Primary Mortgage Insurance, Hazard
Insurance; Claims Thereunder."

                                     - 25 -


SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES; RETAINED INTEREST

         The principal servicing compensation to be paid to the master servicer
in respect of its master servicing activities for a series of securities will be
equal to the percentage or range of percentages per annum described in the
related prospectus supplement of the outstanding principal balance of each
mortgage loan, and this compensation will be retained by it on a monthly or
other periodic basis from collections of interest on each mortgage loan in the
related trust fund at the time the collections are deposited into the applicable
Certificate Account. This portion of the servicing fee will be calculated with
respect to each mortgage loan by multiplying the fee by the principal balance of
the mortgage loan. In addition, the master servicer may retain all prepayment
premiums, assumption fees and late payment charges, to the extent collected from
mortgagors, and any benefit which may accrue as a result of the investment of
funds in the applicable Certificate Account. Any additional servicing
compensation will be described in the related prospectus supplement. Any
subservicer will receive a portion of the master servicer's compensation as its
subservicing compensation.

         In addition to amounts payable to any subservicer, the master servicer
will pay or cause to be paid some of the ongoing expenses associated with each
trust fund and incurred by it in connection with its responsibilities under the
pooling and servicing agreement or servicing agreement, including, if so
specified in the related prospectus supplement, payment of any fee or other
amount payable in respect of any alternative credit enhancement arrangements,
payment of the fees and disbursements of the trustee, any custodian appointed by
the trustee and the security registrar, and payment of expenses incurred in
enforcing the obligations of subservicers and Sellers. The master servicer will
be entitled to reimbursement of expenses incurred in enforcing the obligations
of subservicers and Sellers under limited circumstances. In addition, the master
servicer will be entitled to reimbursements for some of its expenses incurred in
connection with liquidated mortgage loans and in connection with the restoration
of mortgaged properties, this right of reimbursement being prior to the rights
of securityholders to receive any related Liquidation Proceeds or Insurance
Proceeds. If and to the extent so provided in the related prospectus supplement,
the master servicer will be entitled to receive interest on amounts advanced to
cover reimbursable expenses for the period that the advances are outstanding at
the rate specified in the prospectus supplement, and the master servicer will be
entitled to payment of the interest periodically from general collections on the
mortgage loans in the related trust fund prior to any payment to securityholders
or as otherwise provided in the related pooling and servicing agreement or
servicing agreement and described in the prospectus supplement.

         If and to the extent provided in the related prospectus supplement, the
master servicer may be required to apply a portion of the servicing compensation
otherwise payable to it in respect of any period to any Prepayment Interest
Shortfalls resulting from mortgagor prepayments during that period. See "Yield
Considerations."

EVIDENCE AS TO COMPLIANCE

         Each pooling and servicing agreement and servicing agreement will
provide that on or before a specified date in March of each year, beginning with
the first year after the year in which the cut-off date occurs, each party
responsible for the servicing function will provide to



                                     - 26 -


the depositor and the trustee a report on an assessment of compliance with the
minimum servicing criteria established in Item 1122(a) of Regulation AB (the "AB
Servicing Criteria"). The AB Servicing Criteria include specific criteria
relating to the following areas: general servicing considerations, cash
collection and administration, investor remittances and reporting, and pool
asset administration. Such report will indicate that the AB Servicing Criteria
were used to test compliance on a platform level basis and will set out any
material instances of noncompliance.

         Each pooling and servicing agreement and servicing agreement will also
provide that each party responsible for the servicing function will deliver
along with its report on assessment of compliance, an attestation report from a
firm of independent public accountants on the assessment of compliance with the
AB Servicing Criteria.

         Each pooling and servicing agreement and servicing agreement will also
provide for delivery to the trustee, on or before a specified date in March of
each year, of a separate annual statement of compliance from each entity
responsible for the servicing function to the effect that, to the best knowledge
of the signing officer, the servicer has fulfilled in all material respects its
obligations under the pooling and servicing agreement or servicing agreement
throughout the preceding year or, if there has been a material failure in the
fulfillment of any obligation, the statement shall specify such failure and the
nature and status thereof. This statement may be provided as the required
statement for each relevant pooling and servicing agreement or servicing
agreement.

         Copies of the annual reports of assessment of compliance, attestation
reports, and statements of compliance may be obtained by securityholders without
charge upon written request to the master servicer or trustee. These items will
be filed with the issuing entity's annual report on Form 10-K , to the extent
required by Regulation AB.

                          DESCRIPTION OF THE SECURITIES

GENERAL

         The securities will be issued in series. Each series of certificates
(or, in some instances, two or more series of certificates) will be issued
pursuant to a pooling and servicing agreement, similar to one of the forms filed
as an exhibit to the registration statement of which this prospectus is a part.
Each pooling and servicing agreement will be filed with the Commission as an
exhibit to a Current Report on Form 8-K. Each series of notes (or, in some
instances, two or more series of notes) will be issued pursuant to an indenture
between the related Issuing Entity and the trustee, similar to the form filed as
an exhibit to the registration statement of which this prospectus is a part. The
trust fund will be created pursuant to an owner trust agreement between the
depositor and the owner trustee. Each indenture, along with the related
servicing agreement and owner trust agreement, will be filed with the Commission
as an exhibit to a Current Report on Form 8-K. Qualified counsel will render an
opinion to the effect that the trust fund's assets will not be considered assets
of the Seller or the depositor in the event of the bankruptcy Seller or the
depositor. The following summaries (together with additional summaries under
"The Agreements" below) describe the material provisions relating to the
securities common to each Agreements.

                                     - 27 -


         Certificates of each series covered by a particular pooling and
servicing agreement will evidence specified beneficial ownership interests in a
separate trust fund created pursuant to the pooling and servicing agreement.
Each series of notes covered by a particular indenture will evidence
indebtedness of a separate trust fund created pursuant to the related owner
trust agreement. A trust fund will consist of, to the extent provided in the
pooling and servicing agreement or owner trust agreement:

      o     the mortgage loans (and the related mortgage documents) or interests
            therein (including any mortgage securities) underlying a particular
            series of securities as from time to time are subject to the pooling
            and servicing agreement or servicing agreement, exclusive of, if
            specified in the related prospectus supplement, any interest
            retained by the depositor or any of its affiliates with respect to
            each mortgage loan;

      o     all payments and collections in respect of the mortgage loans or
            mortgage securities due after the related cut-off date, as from time
            to time are identified as deposited in respect thereof in the
            related Certificate Account as described below;

      o     any property acquired in respect of mortgage loans in the trust
            fund, whether through foreclosure of a mortgage loan or by deed in
            lieu of foreclosure;

      o     hazard insurance policies, Primary Insurance Policies and FHA
            insurance policies, if any, maintained in respect of mortgage loans
            in the trust fund and the proceeds of these policies;

      o     the rights of the depositor under any mortgage loan purchase
            agreement, including in respect of any representations and
            warranties therein; and

      o     any combination, as and to the extent specified in the related
            prospectus supplement, of a financial guaranty insurance policy,
            mortgage pool insurance policy, letter of credit, special hazard
            insurance policy, or currency or interest rate exchange agreements
            as described under "Description of Credit Enhancement."

         If provided in the related prospectus supplement, the original
principal amount of a series of securities may exceed the principal balance of
the mortgage loans or mortgage securities initially being delivered to the
trustee. Cash in an amount equal to this difference will be deposited into a
pre-funding account maintained with the trustee. During the period set forth in
the related prospectus supplement, amounts on deposit in the pre-funding account
may be used to purchase additional mortgage loans or mortgage securities for the
related trust fund. Any amounts remaining in the pre-funding account at the end
of the period will be distributed as a principal prepayment to the holders of
the related series of securities at the time and in the manner set forth in the
related prospectus supplement.

         Each series of securities may consist of any one or a combination of
the following types of classes:



                        
Accretion Directed         A class of securities  designated  to receive  principal
                           payments  primarily  from the  interest  that accrues on
                           specified Accrual Classes.


                                     - 28 -


Accrual                    A  class  of  securities   where  the  accrued  interest
                           otherwise  payable to such  certificates is allocated to
                           specified classes of certificates as principal  payments
                           in reduction  of their  certificate  principal  balance.
                           The certificate  principal  balance of the Accrual Class
                           will be increased  to the extent such  accrued  interest
                           is so allocated.

Companion                 A  class  that  receives   principal   payments  on  any
                           distribution  date only if scheduled  payments have been
                           made on specified  planned principal  classes,  targeted
                           principal classes or scheduled principal classes.

Component                A class consisting of "components."  The components of a
                           class  of  component   securities   may  have  different
                           principal  and/or interest payment  characteristics  but
                           together  constitute a single class. Each component of a
                           class  of  component  securities  may be  identified  as
                           falling into one or more of the categories in this list.

Fixed Rate                 A class with an interest  rate that is fixed  throughout
                           the life of the class.

Floating Rate            A class  that  receives  interest  payments  based on an
                           interest rate that  fluctuates each payment period based
                           on a designated index plus a specified margin.

Interest Only or IO     A class of  securities  with no  principal  balance  and
                           which is not  entitled to principal  payments.  Interest
                           usually accrues based on a specified notional amount.

Inverse Floating Rate   A  class  of  securities  where  the  pass-through  rate
                           adjusts  based on the excess  between a  specified  rate
                           and LIBOR or another index.

Lock                       Out A class of securities which is "locked out" of
                           certain payments, usually principal, for a specified
                           period of time.

Partial Accrual.           A  class  that  accretes  a  portion  of the  amount  of
                           accrued interest thereon,  which amount will be added to
                           the principal  balance of such class on


                                     - 29 -




                           each  applicable distribution  date,  with the  remainder
                           of such accrued interest  to be  distributed  currently
                           as  interest on such  class.   Such   accretion  may
                           continue  until  a specified  event  has  occurred  or
                           until  such  Partial Accrual class is retired.

Principal Only             A class of securities  which is not entitled to interest payments.

Planned Amortization
Class or PAC               A class of securities  with a principal  balance that is
                           reduced  based  on a  schedule  of  principal  balances,
                           assuming  a  certain  range of  prepayment  rates on the
                           underlying assets.

Scheduled Principal        A class that is designed to receive  principal  payments
                           using a predetermined  principal balance schedule but is
                           not designated as a Planned  Principal Class or Targeted
                           Principal  Class. In many cases, the schedule is derived
                           by  assuming  two  constant  prepayment  rates  for  the
                           underlying  assets.  These two  rates are the  endpoints
                           for the "structuring  range" for the scheduled principal
                           class.

Senior Support             A class that  absorbs  the  realized  losses  other than
                           excess  losses that would  otherwise  be  allocated to a
                           Super  Senior   Class  after  the  related   classes  of
                           subordinated securities are no longer outstanding.

Sequential Pay             Classes that receive principal  payments in a prescribed
                           sequence,  that  do  not  have  predetermined  principal
                           balance  schedules  and  that  under  all  circumstances
                           receive  payments  of  principal  continuously  from the
                           first  distribution date on which they receive principal
                           until they are  retired.  A single  class that  receives
                           principal  payments before or after all other classes in
                           the same series of  securities  may be  identified  as a
                           sequential pay class.

Super Senior               A class  that will not bear its  proportionate  share of
                           realized  losses (other than excess losses) as its share
                           is  directed  to  another  class,  referred  to  as  the
                           "support  class"  until the class  principal  balance of
                           the support class is reduced to zero.


                                     - 30 -



Target                     Amortization or TAC. A class of securities with a principal
                           balance that is reduced based on a scheduled of principal
                           balances, assuming a certain targeted rate of
                           prepayments on the related collateral.

Variable Rate              A class with an interest  rate that resets  periodically
                           and is  calculated  by reference to the rate or rates of
                           interest  applicable to specified  assets or instruments
                           (e.g., the Loan Rates borne by the underlying loans).


With respect to any series of notes, the related Equity Certificates, insofar as
they represent the beneficial ownership interest in the Issuing Entity, will be
subordinate to the related notes. As to each series, the offered securities will
be rated in one of the four highest rating categories by one or more Rating
Agencies. Credit support for the offered securities of each series may be
provided by a financial guaranty insurance policy, mortgage pool insurance
policy, letter of credit, reserve fund, overcollateralization, and currency or
interest rate exchange agreements as described under "Description of Credit
Enhancement," by the subordination of one or more other classes of securities as
described under "Subordination" or by any combination of the foregoing.

         If so specified in the prospectus supplement relating to a series of
certificates, one or more elections may be made to treat the related trust fund,
or a designated portion thereof, as a REMIC. If an election is made with respect
to a series of certificates, one of the classes of certificates in the series
will be designated as evidencing the sole class of "residual interests" in each
related REMIC, as defined in the Code; alternatively, a separate class of
ownership interests will evidence the residual interests. All other classes of
certificates in the series will constitute "regular interests" in the related
REMIC, as defined in the Code. As to each series of certificates as to which a
REMIC election is to be made, the master servicer, trustee or other specified
person will be obligated to take specified actions required in order to comply
with applicable laws and regulations.

FORM OF SECURITIES

         Except as described below, the offered securities of each series will
be issued as physical certificates or notes in fully registered form only in the
denominations specified in the related prospectus supplement, and will be
transferrable and exchangeable at the corporate trust office of the registrar
named in the related prospectus supplement. No service charge will be made for
any registration of exchange or transfer of offered securities, but the trustee
may require payment of a sum sufficient to cover any tax or other governmental
charge. A "securityholder" or "holder" is the entity whose name appears on the
records of the registrar (consisting of or including the security register) as
the registered holder of a security.

         If so specified in the related prospectus supplement, specified classes
of a series of securities will be initially issued through the book-entry
facilities of the DTC. As to any class of DTC Registered Securities, the
recordholder of the securities will be DTC's nominee. DTC is a



                                     - 31 -


limited-purpose trust company organized under the laws of the State of New York,
which holds securities for its participants and facilitates the clearance and
settlement of securities transactions between participants through electronic
book-entry changes in the accounts of participants. Intermediaries have indirect
access to DTC's clearance system.

         No Beneficial Owner will be entitled to receive a Security representing
its interest in registered, certificated form, unless either (1) DTC ceases to
act as depository in respect thereof and a successor depository is not obtained,
or (2) the depositor elects in its sole discretion to discontinue the
registration of the securities through DTC. Prior to one of these events,
Beneficial Owners will not be recognized by the trustee or the master servicer
as holders of the related securities for purposes of the related pooling and
servicing agreement or indenture, and Beneficial Owners will be able to exercise
their rights as owners of the securities only indirectly through DTC,
participants and Intermediaries. Any Beneficial Owner that desires to purchase,
sell or otherwise transfer any interest in DTC Registered Securities may do so
only through DTC, either directly if the Beneficial Owner is a participant or
indirectly through participants and, if applicable, Intermediaries. Pursuant to
the procedures of DTC, transfers of the beneficial ownership of any DTC
Registered Securities will be required to be made in minimum denominations
specified in the related prospectus supplement. The ability of a Beneficial
Owner to pledge DTC Registered Securities to persons or entities that are not
participants in the DTC system, or to otherwise act with respect to the
securities, may be limited because of the lack of physical certificates or notes
evidencing the securities and because DTC may act only on behalf of
participants.

         Distributions in respect of the DTC Registered Securities will be
forwarded by the trustee or other specified person to DTC, and DTC will be
responsible for forwarding the payments to participants, each of which will be
responsible for disbursing the payments to the Beneficial Owners it represents
or, if applicable, to Intermediaries. Accordingly, Beneficial Owners may
experience delays in the receipt of payments in respect of their securities.
Under DTC's procedures, DTC will take actions permitted to be taken by holders
of any class of DTC Registered Securities under the pooling and servicing
agreement or indenture only at the direction of one or more participants to
whose account the DTC Registered Securities are credited and whose aggregate
holdings represent no less than any minimum amount of Percentage Interests or
voting rights required therefor. DTC may take conflicting actions with respect
to any action of holders of securities of any class to the extent that
participants authorize these actions. None of the master servicer, the
depositor, the trustee or any of their respective affiliates will have any
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the DTC Registered Securities, or for
maintaining, supervising or reviewing any records relating to the beneficial
ownership interests.

GLOBAL SECURITIES

         Some of the offered securities may be Global Securities. Except in some
limited circumstances, the Global Securities will be available only in
book-entry form. Investors in the Global Securities may hold those Global
Securities through any of DTC, Clearstream Banking, societe anonyme, formerly
known as Cedelbank SA, or Euroclear. The Global Securities will be



                                     - 32 -


traceable as home market instruments in both the European and U.S. domestic
markets. Initial settlement and all secondary trades will settle in same-day
funds.

         Secondary market trading between investors through Clearstream and
Euroclear will be conducted in the ordinary way in accordance with the normal
rules and operating procedures of Clearstream and Euroclear and in accordance
with conventional eurobond practice (i.e., seven calendar day settlement).

         Secondary market trading between investors through DTC will be
conducted according to DTC's rules and procedures applicable to U.S. corporate
debt obligations.

         Secondary cross-market trading between Clearstream or Euroclear and DTC
participants holding Notes will be effected on a delivery-against-payment basis
through the respective Depositaries of Clearstream and Euroclear (in that
capacity) and as DTC participants.

         Non-U.S. holders (as described below) of Global Securities will be
subject to U.S. withholding taxes unless those holders meet various requirements
and deliver appropriate U.S. tax documents to the securities clearing
organizations or their participants.

         All Global Securities will be held in book-entry form by DTC in the
name of Cede & Co. as nominee of DTC. Investors' interests in the Global
Securities will be represented through financial institutions acting on their
behalf as direct and indirect participants in DTC. As a result, Clearstream and
Euroclear will hold positions on behalf of their participants through their
Relevant Depositary which in turn will hold those positions in their accounts as
DTC participants.

         Investors electing to hold their Global Securities through DTC will
follow DTC settlement practices. Investor securities custody accounts will be
credited with their holdings against payment in same-day funds on the settlement
date.

         Investors electing to hold their Global Securities through Clearstream
or Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" or restricted period. Global Securities will be credited to the
securities custody accounts on the settlement date against payment in same-day
funds.

         Since the purchaser determines the place of delivery, it is important
to establish at the time of the trade where both the purchaser's and seller's
accounts are located to ensure that settlement can be made on the desired value
date.

         Secondary market trading between DTC participants will be settled using
the procedures applicable to prior mortgage loan asset-backed notes issues in
same-day funds. Secondary market trading between Clearstream participants or
Euroclear participants will be settled using the procedures applicable to
conventional eurobonds in same-day funds. When Global Securities are to be
transferred from the account of a DTC participant to the account of a
Clearstream participant or a Euroclear participant, the purchaser will send
instructions to Clearstream or Euroclear through a Clearstream participant or
Euroclear participant at least one business day prior to settlement. Clearstream
or Euroclear will instruct the Relevant Depositary, as the case



                                     - 33 -


may be, to receive the Global Securities against payment. Payment will include
interest accrued on the Global Securities from and including the last coupon
payment date to and excluding the settlement date, on the basis of the actual
number of days in that accrual period and a year assumed to consist of 360 days.
For transactions settling on the 31st of the month, payment will include
interest accrued to and excluding the first day of the following month. Payment
will then be made by the Relevant Depositary to the DTC participant's account
against delivery of the Global Securities. After settlement has been completed,
the Global Securities will be credited to the respective clearing system and by
the clearing system, in accordance with its usual procedures, to the Clearstream
participant's or Euroclear participant's account. The securities credit will
appear the next day (European time) and the cash debt will be back-valued to,
and the interest on the Global Securities will accrue from, the value date
(which would be the preceding day when settlement occurred in New York). If
settlement is not completed on the intended value date (i.e., the trade
fails),the Clearstream or Euroclear cash debt will be valued instead as of the
actual settlement date.

         Clearstream participants and Euroclear participants will need to make
available to the respective clearing systems the funds necessary to process
same-day funds settlement. The most direct means of doing so is to preposition
funds for settlement, either from cash on hand or existing lines of credit, as
they would for any settlement occurring within Clearstream or Euroclear. Under
this approach, they may take on credit exposure to Clearstream or Euroclear
until the Global Securities are credited to their account one day later. As an
alternative, if Clearstream or Euroclear has extended a line of credit to them,
Clearstream participants or Euroclear participants can elect not to preposition
funds and allow that credit line to be drawn upon to finance settlement. Under
this procedure, Clearstream participants or Euroclear participants purchasing
Global Securities would incur overdraft charges for one day, assuming they
cleared the overdraft when the Global Securities were credited to their
accounts. However, interest on the Global Securities would accrue from the value
date. Therefore, in many cases the investment income on the Global Securities
earned during that one-day period may substantially reduce or offset the amount
of those overdraft charges, although the result will depend on each Clearstream
participant's or Euroclear participant's particular cost of funds. Since the
settlement is taking place during New York business hours, DTC participants can
employ their usual procedures for crediting Global Securities to the respective
European depositary for the benefit of Clearstream participants or Euroclear
participants. The sale proceeds will be available to the DTC seller on the
settlement date. Thus, to the DTC participants a cross-market transaction will
settle no differently than a trade between two DTC participants.

         Due to time zone differences in their favor, Clearstream participants
and Euroclear participants may employ their customary procedures for
transactions in which Global Securities are to be transferred by the respective
clearing system, through the respective depositary, to a DTC participant. The
seller will send instructions to Clearstream or Euroclear through a Clearstream
participant or Euroclear participant at least one business day prior to
settlement. In these cases Clearstream or Euroclear will instruct the respective
depositary, as appropriate, to credit the Global Securities to the DTC
participant's account against payment. Payment will include interest accrued on
the Global Securities from and including the last coupon payment to and
excluding the settlement date on the basis of the actual number of days in that
accrual period and a year assumed to consist to 360 days. For transactions
settling on the 31st of the month, payment will include interest accrued to and
excluding the first day of the following month. The



                                     - 34 -


payment will then be reflected in the account of Clearstream participant or
Euroclear participant the following day, and receipt of the cash proceeds in the
Clearstream participant's or Euroclear participant's account would be
back-valued to the value date (which would be the preceding day, when settlement
occurred in New York). Should the Clearstream participant or Euroclear
participant have a line of credit with its respective clearing system and elect
to be in debt in anticipation of receipt of the sale proceeds in its account,
the back-valuation will extinguish any overdraft incurred over that one-day
period. If settlement is not completed on the intended value date (i.e., the
trade fails), receipt of the cash proceeds in the Clearstream participant's or
Euroclear participant's account would instead be valued as of the actual
settlement date.

         Finally, day traders that use Clearstream or Euroclear and that
purchase Global Securities from DTC participants for delivery to Clearstream
participants or Euroclear participants should note that these trades would
automatically fail on the sale side unless affirmative action is taken. At least
three techniques should be readily available to eliminate this potential
problem:

         o        borrowing through Clearstream or Euroclear for one day (until
                  the purchase side of the trade is reflected in their
                  Clearstream or Euroclear accounts) in accordance with the
                  clearing system's customary procedures;

         o        borrowing the Global Securities in the U.S. from a DTC
                  participant no later than one day prior to settlement, which
                  would give the Global Securities sufficient time to be
                  reflected in their Clearstream or Euroclear account in order
                  to settle the sale side of the trade; or

         o        staggering the value dates for the buy and sell sides of the
                  trade so that the value date for the purchase from the DTC
                  participant is at least one day prior to the value date for
                  the sale to the Clearstream participant or Euroclear
                  participant.

         A beneficial owner of Global Securities holding securities through
Clearstream or Euroclear (or through DTC if the holder has an address outside
the U.S.) will be subject to the 30% U.S. withholding tax that generally applies
to payments of interest (including original issue discount) on registered debt
issued by U.S. Persons (as defined below), unless (i) each clearing system, bank
or other financial institution that holds customers' securities in the ordinary
course of its trade or business in the chain of intermediaries between that
beneficial owner and the U.S. entity required to withhold tax complies with
applicable certification requirements and (ii) that beneficial owner takes one
of the following steps to obtain an exemption or reduced tax rate: Exemption for
Non-U.S. Persons (Form W-8BEN). Beneficial holders of Global Securities that are
Non-U.S. Persons (as defined below) can obtain a complete exemption from the
withholding tax by filing a signed Form W-8BEN (Certificate of Foreign Status of
Beneficial Owner for United States Tax Withholding). If the information shown on
Form W-8BEN changes, a new Form W-8BEN must be filed within 30 days of that
change.

         A Non-U.S. Person (as defined below), including a non-U.S. corporation
or bank with a U.S. branch, for which the interest income is effectively
connected with its conduct of a trade or business in the United States, can
obtain an exemption from the withholding tax by filing Form W-8ECI (Exemption
from Withholding of Tax on Income Effectively Connected with the Conduct of a
Trade or Business in the United States).


                                     - 35 -


         Non-U.S. Persons residing in a country that has a tax treaty with the
United States can obtain an exemption or reduced tax rate (depending on the
treaty terms) by filing Form W-8BEN (Holdership, Exemption or Reduced Rate
Certificate). Form W-8BEN may be filed by Noteholders or their agent.

         U.S. Persons can obtain a complete exemption from the withholding tax
by filing Form W-9 (Payer's Request for Taxpayer Identification Number and
Certification).

         The holder of a Global Security or, in the case of a Form W-8BEN or a
Form W-8ECI filer, his agent, files by submitting the appropriate form to the
person through whom it holds the security (the clearing agency, in the case of
persons holding directly on the books of the clearing agency). Form W-8BEN and
Form W-8ECI are effective for three calendar years. The term "U.S. Person" means
a citizen or resident of the United States, a corporation, partnership or other
entity created or organized in, or under the laws of, the United States or any
political subdivision thereof (except, in the case of a partnership, to the
extent provided in regulations), or an estate whose income is subject to United
States federal income tax regardless of its source, or a trust if a court within
the United States is able to exercise primary supervision over the
administration of the trust and one or more United States Persons have the
authority to control all substantial decisions of the trust. The term "Non-U.S.
Person" means any person who is not a U.S. Person. This summary does not deal
with all aspects of U.S. Federal income tax withholding that may be relevant to
foreign holders of the Global Securities. Investors are advised to consult their
own tax advisors for specific tax advice concerning their holding and disposing
of the Global Securities.

ASSIGNMENT OF TRUST FUND ASSETS

         At the time of issuance of a series of securities, the depositor will
assign, or cause to be assigned, to the related trustee (or its nominee),without
recourse, the mortgage loans or mortgage securities being included in the
related trust fund, together with, all principal and interest received on or
with respect to the mortgage loans or mortgage securities after the cut-off
date, other than principal and interest due on or before the cut-off date. If
specified in the related prospectus supplement, the depositor or any of its
affiliates may retain an interest in the trust fund assets, if any, for itself
or transfer the same to others. The trustee will, concurrently with the
assignment, deliver the securities of the series to or at the direction of the
depositor in exchange for the mortgage loans or mortgage securities in the
related trust fund. Each mortgage loan will be identified in a schedule
appearing as an exhibit to the related pooling and servicing agreement or
servicing agreement. The schedule will include, among other things, information
as to the principal balance of each mortgage loan in the related trust fund as
of the cut-off date, as well as information respecting the mortgage rate, the
currently scheduled monthly payment of principal and interest, the maturity of
the mortgage note and the loan-to-value ratio at origination or modification
(without regard to any secondary financing).

      In addition, the depositor will, as to each mortgage loan, other than
mortgage loans underlying any mortgage securities and other than Contracts,
deliver, or cause to be delivered, to the related trustee (or to the custodian
described below) the following documents:


                                     - 36 -


         o        the mortgage note endorsed, without recourse, either in blank
                  or to the order of the trustee (or its nominee),

         o        the mortgage with evidence of recording indicated on the
                  mortgage (except for any mortgage not returned from the public
                  recording office) or, in the case of a cooperative mortgage
                  loan, on the related financing statement,

         o        an assignment of the mortgage in blank or to the trustee (or
                  its nominee) in recordable form (or, with respect to a
                  cooperative mortgage loan, an assignment of the respective
                  security agreements, any applicable UCC financing statements,
                  recognition agreements, relevant stock certificates, related
                  blank stock powers and the related proprietary leases or
                  occupancy agreements),

         o        any intervening assignments of the mortgage with evidence of
                  recording on the assignment (except for any assignment not
                  returned from the public recording office),

         o        if applicable, any riders or modifications to the mortgage
                  note and mortgage, and

         o        any other documents set forth in the related pooling and
                  servicing agreement, mortgage loan purchase agreement or
                  servicing agreement.

The assignments may be blanket assignments covering mortgages on mortgaged
properties located in the same county, if permitted by law.

         Notwithstanding the foregoing, a trust fund may include mortgage loans
where the original mortgage note is not delivered to the trustee if the
depositor delivers, or causes to be delivered, to the related trustee (or the
custodian) a copy or a duplicate original of the mortgage note, together with an
affidavit certifying that the original thereof has been lost or destroyed. In
addition, if the depositor cannot deliver, with respect to any mortgage loan,
the mortgage or any intervening assignment with evidence of recording on the
assignment concurrently with the execution and delivery of the related pooling
and servicing agreement or servicing agreement because of a delay caused by the
public recording office, the depositor will deliver, or cause to be delivered,
to the related trustee (or the custodian) a true and correct photocopy of the
mortgage or assignment as submitted for recording within one year. The depositor
will deliver, or cause to be delivered, to the related trustee (or the
custodian) the mortgage or assignment with evidence of recording indicated on
the assignment after receipt thereof from the public recording office. If the
depositor cannot deliver, with respect to any mortgage loan, the mortgage or any
intervening assignment with evidence of recording on the mortgage or assignment
concurrently with the execution and delivery of the related pooling and
servicing agreement or servicing agreement because the mortgage or assignment
has been lost, the depositor will deliver, or cause to be delivered, to the
related trustee (or the custodian) a true and correct photocopy of the mortgage
or assignment with evidence of recording on the mortgage or assignment.
Assignments of the mortgage loans to the trustee (or its nominee) will be
recorded in the appropriate public recording office, except in states where, in
the opinion of counsel acceptable to the trustee, recording is not required to
protect the trustee's interests in the



                                     - 37 -


mortgage loan against the claim of any subsequent transferee or any successor to
or creditor of the depositor or the originator of the mortgage loan.

         As to each Contract, the depositor will deliver, or cause to be
delivered, to the related trustee (or the custodian) the following documents:

         o        the original Contract endorsed, without recourse, to the order
                  of the trustee,

         o        copies of documents and instruments related to the Contract
                  and the security interest in the Manufactured Home securing
                  the Contract, and

         o        a blanket assignment to the trustee of all Contracts in the
                  related trust fund and the related documents and instruments.

In order to give notice of the right, title and interest of the securityholders
to the Contracts, the depositor will cause to be executed and delivered to the
trustee a UCC-1 financing statement identifying the trustee as the secured party
and identifying all Contracts as collateral.

         The trustee (or the custodian) will hold the documents in trust for the
benefit of the related securityholders, and generally will review the documents
within 120 days after receipt thereof in the case of documents delivered
concurrently with the execution and delivery of the related pooling and
servicing agreement or indenture, and within the time period specified in the
related pooling and servicing agreement or indenture in the case of all other
documents delivered. If any document is found to be missing or defective in any
material respect, the trustee (or the custodian) will be required to promptly so
notify the master servicer, the depositor, and the related Seller. If the
related Seller does not cure the omission or defect within a specified period
after notice is given thereto by the trustee, and the omission or defect
materially and adversely affects the interests of securityholders in the
affected mortgage loan, then, the related Seller will be obligated to purchase
the mortgage loan from the trustee at its purchase price (or, if and to the
extent it would otherwise be permitted to do so for a breach of representation
and warranty as described under "The Mortgage Pools--Representations of
Sellers," to substitute for the mortgage loan). The trustee will be obligated to
enforce this obligation of the Seller to the extent described above under "The
Mortgage Pools--Representations by Sellers," but there can be no assurance that
the applicable Seller will fulfill its obligation to purchase (or substitute
for) the affected mortgage loan as described above. The depositor will not be
obligated to purchase or substitute for the mortgage loan if the Seller defaults
on its obligation to do so. This purchase or substitution obligation constitutes
the sole remedy available to the related securityholders and the related trustee
for omission of, or a material defect in, a constituent document. Any affected
mortgage loan not so purchased or substituted for shall remain in the related
trust fund.


                                     - 38 -


         The trustee will be authorized at any time to appoint one or more
custodians pursuant to a custodial agreement to hold title to the mortgage loans
and/or mortgage securities in any mortgage pool, and to maintain possession of
and, if applicable, to review, the documents relating to the mortgage loans
and/or mortgage securities, in any case as the agent of the trustee. The
identity of any custodian to be appointed on the date of initial issuance of the
securities will be set forth in the related prospectus supplement. A custodian
may be an affiliate of the depositor or the master servicer.

         Except in the case of a Designated Seller Transaction or as to mortgage
loans underlying any mortgage securities, the depositor will make
representations and warranties as to the types and geographical concentrations
of the mortgage loans and as to the accuracy of some of the information
furnished to the related trustee in respect of each mortgage loan (for example,
the original Loan-to-Value Ratio, the principal balance as of the cut-off date,
the mortgage rate and maturity). Upon a breach of any of these representations
which materially and adversely affects the interests of the securityholders in a
mortgage loan, the depositor will be obligated to cure the breach in all
material respects, to purchase the mortgage loan at its purchase price or, to
substitute for the mortgage loan a Qualified Substitute Mortgage Loan in
accordance with the provisions for substitution by Affiliated Sellers as
described above under "The Mortgage Pools--Representations by Sellers." However,
the depositor will not be required to repurchase or substitute for any mortgage
loan in connection with a breach of a representation and warranty if the
substance of the breach also constitutes fraud in the origination of the related
mortgage loan. This purchase or substitution obligation constitutes the sole
remedy available to securityholders or the trustee for a breach of a
representation by the depositor. Any mortgage loan not so purchased or
substituted for shall remain in the related trust fund.

         Pursuant to the related pooling and servicing agreement or servicing
agreement, the master servicer for any mortgage pool, either directly or through
subservicers, will service and administer the mortgage loans included in the
mortgage pool and assigned to the related trustee as more fully set forth under
"Servicing of Mortgage Loans." The master servicer will make representations and
warranties regarding its authority to enter into, and its ability to perform its
obligations under, the pooling and servicing agreement or servicing agreement.

CERTIFICATE ACCOUNT

         GENERAL. The master servicer and/or the trustee will, as to each trust
fund, establish and maintain or cause to be established and maintained a
Certificate Account, which will be established so as to comply with the
standards of each Rating Agency that has rated any one or more classes of
securities of the related series. A Certificate Account shall be maintained as
an Eligible Account, and the funds held therein may be held as cash or invested
in Permitted Investments. The master servicer will have sole discretion to
determine the particular investments made so long as it complies with the
investment terms of the related pooling and servicing agreement or the related
servicing agreement and indenture. Any Permitted Investments shall not cause the
depositor to register under the Investment Company Act of 1940. Any interest or
other income earned on funds in the Certificate Account will be paid to the
related master servicer or trustee as additional compensation. If permitted by
the Rating Agency or Agencies and so specified in the related prospectus
supplement, a Certificate Account may contain funds relating to more than one
series of mortgage pass-through certificates and may

contain other funds representing payments on mortgage loans owned by the related
master servicer or serviced by it on behalf of others.

         DEPOSITS. With respect to each series of securities, the related master
servicer, trustee or special servicer will be required to deposit or cause to be

following receipt (in the case of collections and payments), the following

         o        any advances made as described under "--Advances" below;

         o        any Buydown Funds (and, if applicable, investment earnings on

         o        to the extent that any item does not constitute additional
                  servicing compensation to the master servicer or a special
                  servicer, any payments on account of modification or
                  assumption fees, late payment charges or prepayment premiums

                  case may be, of funds held in the Certificate Account; and

         o        any other amounts required to be deposited in the Certificate
                  Account as provided in the related pooling and servicing
                  agreement or the related servicing agreement

                                     - 40 -


                  and indenture and described in this prospectus or in the
                  related prospectus supplement.

         With respect to each buydown mortgage loan, the master servicer will be
required to deposit the related Buydown Funds provided to it in a Buydown
Account which will comply with the requirements set forth in this prospectus
with respect to the Certificate Account. The terms of all buydown mortgage loans
provide for the contribution of Buydown Funds in an amount equal to or exceeding
either (1) the total payments to be made from the funds pursuant to the related
buydown plan or (2) if the Buydown Funds are to be deposited on a discounted
basis, that amount of Buydown Funds which, together with investment earnings on
the Buydown Funds at a rate as will support the scheduled level of payments due
under the buydown mortgage loan. Neither the master servicer nor the depositor
will be obligated to add to any discounted Buydown Funds any of its own funds
should investment earnings prove insufficient to maintain the scheduled level of
payments. To the extent that any insufficiency is not recoverable from the
mortgagor or, in an appropriate case, from the Seller, distributions to
securityholders may be affected. With respect to each buydown mortgage loan, the
master servicer will be required monthly to withdraw from the Buydown Account
and deposit in the Certificate Account as described above the amount, if any, of
the Buydown Funds (and, if applicable, investment earnings on the Buydown
Funds)for each buydown mortgage loan that, when added to the amount due from the
mortgagor on the buydown mortgage loan, equals the full monthly payment which
would be due on the buydown mortgage loan if it were not subject to the buydown
plan. The Buydown Funds will in no event be a part of the related trust fund.

         If the mortgagor on a buydown mortgage loan prepays the mortgage loan
in its entirety during the Buydown Period, the master servicer will be required
to withdraw from the Buydown Account and remit to the mortgagor or the other
designated party in accordance with the related buydown plan any Buydown Funds
remaining in the Buydown Account. If a prepayment by a mortgagor during the
Buydown Period together with Buydown Funds will result in full prepayment of a
buydown mortgage loan, the master servicer generally will be required to
withdraw from the Buydown Account and deposit in the Certificate Account the
Buydown Funds and investment earnings on the Buydown Funds, if any, which
together with the prepayment will result in a prepayment in full; provided that
Buydown Funds may not be available to cover a prepayment under some mortgage
loan programs. Any Buydown Funds so remitted to the master servicer in
connection with a prepayment described in the preceding sentence will be deemed
to reduce the amount that would be required to be paid by the mortgagor to repay
fully the related mortgage loan if the mortgage loan were not subject to the
buydown plan. Any investment earnings remaining in the Buydown Account after
prepayment or after termination of the Buydown Period will be remitted to the
related mortgagor or the other designated party pursuant to the Buydown
Agreement relating to each buydown mortgage loan. If the mortgagor defaults
during the Buydown Period with respect to a buydown mortgage loan and the
property securing the buydown mortgage loan is sold in liquidation (either by
the master servicer, the primary insurer, any pool insurer or any other
insurer), the master servicer will be required to withdraw from the Buydown
Account the Buydown Funds and all investment earnings on the Buydown Funds, if
any, and either deposit the same in the Certificate Account or, alternatively,
pay the same to the primary insurer or the pool insurer, as the case may be, if
the mortgaged property is transferred to the insurer and the insurer pays all of
the loss incurred in respect of the default.

         WITHDRAWALS. With respect to each series of securities, the master
servicer, trustee or special servicer may make withdrawals from the Certificate
Account for the related trust fund for any of the following purposes, unless
otherwise provided in the related agreement and described in the related
prospectus supplement:

                  these reimbursement to be made out of amounts received which
                  were identified and applied by the master servicer as late
                  collections of interest (net of related servicing fees) on and
                  principal of the particular mortgage loans with respect to

                  form of credit enhancement with respect to the mortgage loans;

         (3)      to reimburse the master servicer or a special servicer for
                  unpaid servicing fees earned by it and some unreimbursed

                  loans in the trust fund and properties acquired in respect
                  thereof, these reimbursement to be made out of amounts that
                  represent Liquidation Proceeds and Insurance Proceeds
                  collected on the particular mortgage loans and properties, and

                  incurred by it which, in the good faith judgment of the master

                  amounts described in clauses (2) and (3), respectively, the
                  reimbursement to be made from amounts collected on other

                  provided by the related pooling and servicing agreement or the
                  related servicing agreement and indenture and described in the
                  related prospectus supplement, only from that portion of
                  amounts collected on the other mortgage loans that is
                  otherwise distributable on one or more classes of subordinate
                  securities of the related series;

         (5)      if and to the extent described in the related prospectus
                  supplement, to pay the master servicer, a special servicer or

                  enhancement) interest accrued on the advances described in
                  clause (2) above made by it and the servicing expenses

         (6)      to reimburse the master servicer, the depositor, or any of
                  their respective directors, officers, employees and agents, as
                  the case may be, for expenses, costs



                                     - 42 -


                  and liabilities incurred thereby, as and to the extent

         (10)     to pay (generally from related income) the master servicer or

                  in lieu of foreclosure;

         (11)     if one or more elections have been made to treat the trust

                  which the related purchase price is determined;

         (15)     to make any other withdrawals permitted by the related pooling

                  termination of the trust fund.

DISTRIBUTIONS

         Distributions on the securities of each series will be made by or on
behalf of the related trustee or master servicer on each distribution date as
specified in the related prospectus supplement from the available distribution
amount for the series and the distribution date. The available distribution
amount for any series of securities and any distribution date will generally
refer to the total of all payments or other collections (or advances in lieu
thereof) on, under or in respect of the mortgage loans and/or mortgage
securities and any other assets included in the related trust fund that are
available for distribution to the securityholders of the series on that date.
The particular components of the available distribution amount for any series on
each distribution date will be more specifically described in the related
prospectus supplement.

         Distributions on the securities of each series (other than the final
distribution in retirement of any certificate) will be made to the persons in
whose names the securities are registered on the Record Date, and the amount of
each distribution will be determined as of the Determination Date. All
distributions with respect to each class of securities on each distribution date
will be allocated in equal proportion among the outstanding securities in the
class. Payments will be made either by wire transfer in immediately available
funds to the account of a securityholder at a bank or other entity having
appropriate facilities therefor, if the securityholder has provided the trustee
or other person required to make the payments with wiring instructions no later
than five business days prior to the related Record Date or other date specified
in the related prospectus supplement (and, if so provided in the related
prospectus supplement, the securityholder holds securities in the requisite
amount or denomination specified therein), or by check mailed to the address of
the securityholder as it appears on the security register; provided, however,
that the final distribution in retirement of any class of securities will be
made only upon presentation and surrender of the securities at the location
specified in the notice to securityholders of the final distribution. Payments
will be made to each certificateholder in accordance with the holder's
Percentage Interest in a particular class.

DISTRIBUTIONS OF INTEREST AND PRINCIPAL ON THE SECURITIES

         Each class of securities of each series, other than Strip Securities
and REMIC Residual Certificates that have no security interest rate, may have a
different per annum rate at which interest accrues on that class of securities,
which may be fixed, variable or adjustable, or any combination of rates. The
related prospectus supplement will specify the security interest rate or, in the
case of a variable or adjustable security interest rate, the method for
determining the security interest rate, for each class. All indices that apply
to pool assets with adjustable rates will be indices that are of a type that are
customarily used in the debt and fixed income markets to measure the cost of
borrowed funds. The related prospectus supplement will specify whether



                                     - 44 -


interest on the securities of the series will be calculated on the basis of a
360-day year consisting of twelve 30-day months or on a different method.

         Distributions of interest in respect of the securities of any class,
other than any class of Accrual Securities, Strip Securities or REMIC Residual
Certificates that is not entitled to any distributions of interest, will be made
on each distribution date based on the accrued interest for the class and the
distribution date, subject to the sufficiency of the portion of the available
distribution amount allocable to the class on the distribution date. Prior to
the time interest is distributable on any class of Accrual Securities, the
amount of accrued interest otherwise distributable on the class will be added to
the principal balance thereof on each distribution date. With respect to each
class of interest-bearing securities, accrued interest for each distribution
date will be equal to interest at the applicable security interest rate accrued
for a specified period (generally one month) on the outstanding principal
balance thereof immediately prior to the distribution date. Accrued interest for
each distribution date on Strip Securities entitled to distributions of interest
will be similarly calculated except that it will accrue on a notional amount
that is based on either (1) based on the principal balances of some or all
of the mortgage loans and/or mortgage securities in the related trust fund or
(2) equal to the principal balances of one or more other classes of securities
of the same series. Reference to a notional amount with respect to a class of
Strip Securities is solely for convenience in making calculations of accrued
interest and does not represent the right to receive any distribution of
principal. If so specified in the related prospectus supplement, the amount of
accrued interest that is otherwise distributable on (or, in the case of Accrual
Securities, that may otherwise be added to the principal balance of) one or more
classes of the securities of a series will be reduced to the extent that any
Prepayment Interest Shortfalls, as described under "Yield Considerations",
exceed the amount of any sums (including, if and to the extent specified in the
related prospectus supplement, the master servicer's servicing compensation)
that are applied to offset the shortfalls. The particular manner in which the
shortfalls will be allocated among some or all of the classes of securities of
that series will be specified in the related prospectus supplement. The related
prospectus supplement will also describe the extent to which the amount of
accrued interest that is otherwise distributable on (or, in the case of Accrual
Securities, that may otherwise be added to the principal balance of) a class of
offered securities may be reduced as a result of any other contingencies,
including delinquencies, losses and Deferred Interest on or in respect of the
related mortgage loans or application of the Relief Act with respect to the
mortgage loans. Any reduction in the amount of accrued interest otherwise
distributable on a class of securities by reason of the allocation to the class
of a portion of any Deferred Interest on or in respect of the related mortgage
loans will result in a corresponding increase in the principal balance of the
class.

         As and to the extent described in the related prospectus supplement,
distributions of principal with respect to a series of securities will be made
on each distribution date to the holders of the class or classes of securities
of the series entitled thereto until the principal balance(s) of the securities
have been reduced to zero. In the case of a series of securities which includes
two or more classes of securities, the timing, sequential order, priority of
payment or amount of distributions in respect of principal, and any schedule or
formula or other provisions applicable to the determination thereof (including
distributions among multiple classes of senior securities or subordinate
securities), shall be as set forth in the related prospectus supplement.
Distributions of principal with respect to one or more classes of securities may
be made at a rate



                                     - 45 -


that is faster (and, in some cases, substantially faster) than the rate at which
payments or other collections of principal are received on the mortgage loans
and/or mortgage securities in the related trust fund, may not commence until the
occurrence of events such as the retirement of one or more other classes of
securities of the same series, or maybe made at a rate that is slower (and, in
some cases, substantially slower) than the rate at which payments or other
collections of principal are received on the mortgage loans and/or mortgage
securities. In addition, distributions of principal with respect to one or more
classes of securities may be made, subject to available funds, based on a
specified principal payment schedule and, with respect to one or more classes of
securities, may be contingent on the specified principal payment schedule for
another class of the same series and the rate at which payments and other
collections of principal on the mortgage loans and/or mortgage securities in the
related trust fund are received.

PRE-FUNDING ACCOUNT

         If so specified in the related prospectus supplement, the pooling and
servicing agreement or other agreement may provide for the transfer by the
Sellers of additional mortgage loans to the related trust after the Closing
Date. The additional mortgage loans will be required to conform to the
requirements set forth in the related Agreement or other agreement providing for
the transfer, and will be underwritten to the same standards as the mortgage
loans initially included in the trust fund as described in the prospectus
supplement. As specified in the related prospectus supplement, the transfer
maybe funded by the establishment of a pre-funding account with the trustee. If
a pre-funding account is established, all or a portion of the proceeds of the
sale of one or more classes of securities of the related series will be
deposited in the account to be released as additional mortgage loans are
transferred. A pre-funding account will be required to be maintained as an
Eligible Account, the amounts therein may be required to be invested in
Permitted Investments and the amount held therein shall at no time exceed 50% of
the proceeds of the offering of the related securities. The related Agreement or
other agreement providing for the transfer of additional mortgage loans
generally will provide that the transfers must be made within up to three months
(with respect to any series of certificates) or up to, but not in excess of, one
year (with respect to any series of notes) after the Closing Date, and that
amounts set aside to fund the transfers (whether in a pre-funding account or
otherwise) and not so applied within the required period of time will be deemed
to be principal prepayments and applied in the manner set forth in the
prospectus supplement. To the extent amounts in any pre-funding account have not
been used to purchase additional mortgage loans, holders of the securities may
receive an additional prepayment, which may affect their yield to maturity. In
addition, securityholders may not be able to reinvest amounts received from any
pre-funding account in comparable securities, or may only be able to do so at a
lower interest rate.

DISTRIBUTIONS ON THE SECURITIES IN RESPECT OF PREPAYMENT PREMIUMS

         Prepayment premiums will generally be retained by the master servicer
or by the Seller as additional compensation. However, if so provided in the
related prospectus supplement, prepayment premiums received on or in connection
with the mortgage loans or mortgage securities in any trust fund will be
distributed on each distribution date to the holders of the class or classes of
securities of




                                     - 46 -


the related series entitled thereto in accordance with the provisions described
in the prospectus supplement.

ALLOCATION OF LOSSES AND SHORTFALLS

         The amount of any losses or shortfalls in collections on the mortgage
loans or mortgage securities in any trust fund (to the extent not covered or
offset by draws on any reserve fund or under any instrument of credit
enhancement) will be allocated among the respective classes of securities of the
related series in the priority and manner, and subject to the limitations,
specified in the related prospectus supplement. As described in the related
prospectus supplement, these allocations may result in reductions in the
entitlements to interest and/or principal balances of one or more classes of
securities, or may be effected simply by a prioritization of payments among
classes of securities.

ADVANCES

         If and to the extent provided in the related prospectus supplement, and
subject to any limitations specified therein, the related master servicer may be
obligated to advance, or have the option of advancing, on or before each
distribution date, from its or their own funds or from excess funds held in the
related Certificate Account that are not part of the available distribution
amount for the related series of securities for the distribution date, an amount
up to the aggregate of any payments of interest (and, if specified in the
related prospectus supplement, principal) that were due on or in respect of the
mortgage loans during the related Due Period and were delinquent on the related
Determination Date. No notice will be given to the certificateholders of these
advances. Scheduled payments on the mortgage loans in any trust fund that became
due during a given Due Period will, to the extent received by the related
Determination Date or advanced by the related master servicer or other specified
person, be distributed on the distribution date next succeeding the
Determination Date. Advances are intended to maintain a regular flow of
scheduled interest and principal payments to holders of the class or classes of
securities entitled thereto, rather than to guarantee or insure against losses.
Accordingly, all advances made from the master servicer's own funds will be
reimbursable out of related recoveries on the mortgage loans (including amounts
received under any fund or instrument constituting credit enhancement)
respecting which advances were made and other specific sources as may be
identified in the related prospectus supplement, including amounts which would
otherwise be payable to the offered securities. No Nonrecoverable Advance will
be required to be made by the master servicer; and, if previously made by a
master servicer, a Nonrecoverable Advance will be reimbursable from any amounts
in the related Certificate Account prior to any distributions being made to the
related series of securityholders. If advances have been made from excess funds
in a Certificate Account, the master servicer that advanced the funds will be
required to replace the funds in the Certificate Account on any future
distribution date to the extent that funds then in the Certificate Account are
insufficient to permit full distributions to securityholders on that date. If so
specified in the related prospectus supplement, the obligation of a master
servicer to make advances maybe secured by a cash advance reserve fund or a
surety bond. If applicable, information regarding the characteristics of, and
the identity of any obligor on, a surety bond, will be set forth in the related
prospectus



                                     - 47 -


supplement. If any person other than the master servicer has any obligation to
make advances as described above, the related prospectus supplement will
identify the person. If and to the extent so provided in the related prospectus
supplement, any entity making advances will be entitled to receive interest on
the advances for the period that the advances are outstanding at the rate
specified in the prospectus supplement, and the entity will be entitled to
payment of the interest periodically from general collections on the mortgage
loans in the related trust fund prior to any payment to securityholders or as
otherwise provided in the related pooling and servicing agreement or servicing
agreement and described in the prospectus supplement. As specified in the
related prospectus supplement with respect to any series of securities as to
which the trust fund includes mortgage securities, the advancing obligations
with respect to the underlying mortgage loans will be pursuant to the terms of
the mortgage securities, as may be supplemented by the terms of the applicable
pooling and servicing agreement or servicing agreement, and may differ from the
provisions described above.



MODIFICATIONS

         In instances in which a mortgage loan is in default or if default is
reasonably foreseeable, and if determined by the master servicer to be in the
best interest of the securityholders, the master servicer or servicer may permit
servicing modifications of the mortgage loan rather than proceeding with
foreclosure. However, the master servicer's and the servicer's ability to
perform servicing modifications will be subject to some limitations, including
but not limited to the following. Advances and other amounts may be added to the
outstanding principal balance of a mortgage loan only once during the life of a
mortgage loan. Any amounts added to the principal balance of the mortgage loan,
or capitalized amounts added to the mortgage loan, will be required to be fully
amortized over the remaining term of the mortgage loan. All capitalizations are
to be implemented in accordance with the sponsor's standards and may be
implemented only by servicers that have been approved by the master servicer for
that purpose. The final maturity of any mortgage loan shall not be extended
beyond the assumed final distribution date. No servicing modification with
respect to a mortgage loan will have the effect of reducing the mortgage rate
below one half of the mortgage rate as in effect on the cut off date, but not
less than the servicing fee rate. Further, the aggregate current principal
balance of all mortgage loans subject to modifications can be no more than five
percent (5%) of the aggregate principal balance of the mortgage loans as of the
cut off date, but this limit may increase from time to time with the consent of
the rating agencies.

         Any Advances made on any mortgage loan will be reduced to reflect any
related servicing modifications previously made. The mortgage rate and Net
Mortgage Rate as to any mortgage loan will be deemed not reduced by any
servicing modification, so that the calculation of accrued certificate interest
(as defined in the prospectus supplement) payable on the offered securities will
not be affected by the servicing modification.

REPORTS TO SECURITYHOLDERS

         With each distribution to securityholders of a particular class of
offered securities, the related master servicer or trustee will forward or cause
to be forwarded to each holder of record of the class of securities a statement
or statements with respect to the related trust fund setting forth the
information specifically described in the related pooling and servicing
agreement or the related servicing agreement or indenture, which generally will
include the following as applicable except as otherwise provided therein:

                  (by class and any shortfalls or carry-forwards);

         o        the amount, if any, of the distribution allocable to
                  prepayment premiums;

                  class after giving effect to the distribution of principal on
                  the distribution date;

         o        number and amount of pool assets, together with updated pool
                  composition information;

         o        the aggregate amount of advances included in the distributions
                  on the distribution date (including the general purpose of
                  such advances), the aggregate amount of unreimbursed advances
                  at the close of business on the distribution date, and the
                  general source of funds for reimbursements;

         o        if applicable, material modifications, extensions or waivers
                  to pool asset terms, fees, penalties or payments during the
                  distribution period or that have become material over time;

         o        material breaches of pool asset representation or warranties
                  or transaction covenants;

                                     - 49 -


         o        information on loss, delinquency or other tests used for
                  determining early amortization, liquidation, stepdowns or
                  other performance triggers as more completely described in the
                  prospectus supplement and whether the trigger was met;

         o        information regarding any new issuance of securities backed by
                  the same asset pool, any pool asset changes, such as additions
                  or removals in connection with a prefunding and pool asset
                  substitutions and repurchases, and cash flows available for
                  future purchases, such as the balances of any prefunding, if
                  applicable;

         o        any material changes in the solicitation, credit-granting,
                  underwriting, origination, acquisition or pool selection
                  criteria or procedures, as applicable, used to originate,
                  acquire or select new pool assets;

         o        the number and aggregate principal balance of any mortgage
                  loans in the related mortgage pool in respect of which (A) one
                  scheduled payment is delinquent, (B) two scheduled payments
                  are delinquent, (C) three or more scheduled payments are
                  delinquent and (D) foreclosure proceedings have been
                  commenced, and loss information for the period;

         o        the book value of any real estate acquired the trust fund by
                  foreclosure or by a deed in lieu of foreclosure;

         o        the Special Hazard Amount, Fraud Loss Amount and Bankruptcy
                  Amount as of the close of business on the applicable
                  distribution date and a description of any change in the
                  calculation of these amounts; and

         o        any other material information as required under the related
                  pooling and servicing agreement.

In the case of information furnished pursuant to the fifth, sixth and seventh
items above, the amounts will be expressed as a dollar amount per minimum
denomination of the relevant class of offered securities or per a specified
portion of the minimum denomination. In addition to the information described
above, reports to securityholders will contain other information as is set forth
in the applicable pooling and servicing agreement or the applicable servicing
agreement or indenture, which may include prepayments, reimbursements to
subservicers and the master servicer and losses borne by the related trust fund.
In addition, within a reasonable period of time after the end of each calendar
year, the master servicer or trustee will furnish a report to each holder of
record of a class of offered securities at any time during the calendar year
which, for example, will include information as to the aggregate of amounts
reported pursuant to the fifth, sixth and seventh items above for the calendar
year or, in the event the person was a holder of record of a class of securities
during a portion of the calendar year, for the applicable portion of the year.
Reports, whether monthly or annual, will be transmitted in paper format to the
holder of record of the class of securities contemporaneously with the
distribution on that particular class. In addition, the monthly reports will be
posted on a website as described below under "Available Information" and
"Reports to Securityholders."

                        DESCRIPTION OF CREDIT ENHANCEMENT

GENERAL

         Credit support with respect to the offered securities of each series
may be comprised of one or more of the following components. Each component will
have limitations and will provide coverage with respect to Realized Losses on
the related mortgage loans. Credit support will cover Defaulted Mortgage Losses,
but coverage may be limited or unavailable with respect to Special Hazard
Losses, Fraud Losses, Bankruptcy Losses and Extraordinary Losses. To the extent
that the credit support for the offered securities of any series is exhausted,
the holders thereof will bear all further risk of loss.

         As set forth below and in the applicable prospectus supplement,
coverage with respect to Realized Losses may be provided by one or more of a
financial guaranty insurance policy, a special hazard insurance policy, a
mortgage pool insurance policy or a letter of credit. In addition, if provided
in the applicable prospectus supplement, in lieu of or in addition to any or all
of the foregoing arrangements, credit enhancement may be in the form of a
reserve fund to cover the losses, in the form of subordination of one or more
classes of subordinate securities to provide credit support to one or more
classes of senior securities, in the form of overcollateralization, or in the
form of a combination of the foregoing. The credit support may be provided by an
assignment of the right to receive specified cash amounts, a deposit of cash
into a reserve fund or other pledged assets, or by banks, insurance companies,
guarantees or any combination thereof identified in the applicable prospectus
supplement.

         In general, references to "mortgage loans" under this "Description of
Credit Enhancement" section are to mortgage loans in a trust fund. However, if
so provided in the prospectus supplement for a series of securities, the related
underlying mortgage loans may be covered by one or more of the types of credit
support described in this prospectus. The related prospectus supplement will
specify, as to each form of credit support, the information indicated below with
respect thereto, to the extent the information is material and available.

SUBORDINATE SECURITIES

         If so specified in the related prospectus supplement, one or more
classes of securities of a series may be subordinate securities. To the extent
specified in the related prospectus supplement, the rights of the holders of
subordinate securities to receive distributions from the Certificate Account on
any distribution date will be subordinated to the corresponding rights of the
holders of senior securities. If so provided in the related prospectus
supplement, the subordination of a class may apply only in the event of (or may
be limited to) some types of losses or shortfalls. The related prospectus
supplement will set forth information concerning the manner and amount of
subordination provided by a class or classes of subordinate securities in a
series and the circumstances under which the subordination will be available.
The offered securities of any series may include one or more classes of
subordinate securities.



                                     - 51 -


CROSS-SUPPORT

         If the mortgage loans and/or mortgage securities in any trust fund are
divided into separate groups, each supporting a separate class or classes of
securities of the related series, credit enhancement may be provided by
cross-support provisions requiring that distributions be made on senior
securities evidencing interests in one group of mortgage loans and/or mortgage
securities prior to distributions on subordinate securities evidencing interests
in a different group of mortgage loans and/or mortgage securities within the
trust fund. The prospectus supplement for a series that includes a cross-support
provision will describe the manner and conditions for applying the provisions.

OVERCOLLATERALIZATION

         If so specified in the related prospectus supplement, interest
collections on the mortgage loans may exceed interest payments on the securities
for the related distribution date. The excess interest may be deposited into a
reserve fund or applied as a payment of principal on the securities. To the
extent excess interest is applied as principal payments on the securities, the
effect will be to reduce the principal balance of the securities relative to the
outstanding balance of the mortgage loans, thereby creating
overcollateralization and additional protection to the security holders, as
specified in the related prospectus supplement. If so provided in the related
prospectus supplement, overcollateralization may also be provided as to any
series of securities by the issuance of securities in an initial aggregate
principal amount which is less than the aggregate principal amount of the
related mortgage loans.

FINANCIAL GUARANTY INSURANCE POLICY

         If so specified in the related prospectus supplement, a financial
guaranty insurance policy may be obtained and maintained for a class or series
of securities. The insurer with respect to a financial guaranty insurance policy
will be described in the related prospectus supplement and a copy of the form of
financial guaranty insurance policy will be filed with the related Current
Report on Form 8-K.

         A financial guaranty insurance policy will be unconditional and
irrevocable and will guarantee to holders of the applicable securities that an
amount equal to the full amount of payments due to the holders will be received
by the trustee or its agent on behalf of the holders for payment on each
distribution date. The specific terms of any financial guaranty insurance policy
will be set forth in the related prospectus supplement. A financial guaranty
insurance policy may have limitations and generally will not insure the
obligation of the Sellers or the master servicer to purchase or substitute for a
defective mortgage loan and will not guarantee any specific rate of principal
prepayments. The insurer will be subrogated to the rights of each holder to the
extent the insurer makes payments under the financial guaranty insurance policy.

MORTGAGE POOL INSURANCE POLICIES

         Any mortgage pool insurance policy obtained by the depositor for each
trust fund will be issued by the pool insurer named in the applicable prospectus
supplement. Each mortgage pool



                                     - 52 -


insurance policy will, subject to the limitations
described below, cover Defaulted Mortgage Losses in an amount equal to a
percentage specified in the applicable prospectus supplement of the aggregate
principal balance of the mortgage loans on the cut-off date. As set forth under
"Maintenance of Credit Enhancement," the master servicer will use reasonable
efforts to maintain the mortgage pool insurance policy and to present claims
thereunder to the pool insurer on behalf of itself, the related trustee and the
related securityholders. The mortgage pool insurance policies, however, are not
blanket policies against loss, since claims thereunder may only be made
respecting particular defaulted mortgage loans and only upon satisfaction of the
conditions precedent described below. Unless specified in the related prospectus
supplement, the mortgage pool insurance policies may not cover losses due to a
failure to pay or denial of a claim under a Primary Insurance Policy,
irrespective of the reason therefor. Each mortgage pool insurance policy will
generally provide that no claims may be validly presented thereunder unless,
among other things:

         o        any required Primary Insurance Policy is in effect for the
                  defaulted mortgage loan and a claim thereunder has been
                  submitted and settled,

         o        hazard insurance on the property securing the mortgage loan
                  has been kept in force and real estate taxes and other
                  protection and preservation expenses have been paid by the
                  master servicer,

         o        if there has been physical loss or damage to the mortgaged
                  property, it has been restored to its condition (reasonable
                  wear and tear excepted) at the cut-off date and

         o        the insured has acquired good and merchantable title to the
                  mortgaged property free and clear of liens, except for
                  permitted encumbrances.

Upon satisfaction of these conditions, the pool insurer will have the option
either (1) to purchase the property securing the defaulted mortgage loan at a
price equal to the principal balance thereof plus accrued and unpaid interest at
the applicable mortgage rate to the date of purchase and expenses incurred by
the master servicer, special servicer or subservicer on behalf of the related
trustee and securityholders, or (2) to pay the amount by which the sum of the
principal balance of the defaulted mortgage loan plus accrued and unpaid
interest at the mortgage rate to the date of payment of the claim and the
aforementioned expenses exceeds the proceeds received from an approved sale of
the mortgaged property, in either case net of amounts paid or assumed to have
been paid under any related Primary Insurance Policy. Securityholders will
experience a shortfall in the amount of interest payable on the related
securities in connection with the payment of claims under a mortgage pool
insurance policy because the pool insurer is only required to remit unpaid
interest through the date a claim is paid rather than through the end of the
month in which the claim is paid. In addition, the securityholders will also
experience losses with respect to the related securities in connection with
payments made under a mortgage pool insurance policy to the extent that the
master servicer expends funds to cover unpaid real estate taxes or to repair the
related mortgaged property in order to make a claim under a mortgage pool
insurance policy, as those amounts will not be covered by payments under the
policy and will be reimbursable to the master servicer from funds otherwise
payable to the securityholders. If any mortgaged property securing a defaulted
mortgage loan is damaged and proceeds, if any (see "--



                                     - 53 -


Special Hazard Insurance Policies" below for risks which are not covered by the
policies), from the related hazard insurance policy or applicable special hazard
insurance policy are insufficient to restore the damaged property to a condition
sufficient to permit recovery under the mortgage pool insurance policy, the
master servicer is not required to expend its own funds to restore the damaged
property unless it determines (x) that the restoration will increase the
proceeds to one or more classes of securityholders on liquidation of the
mortgage loan after reimbursement of the master servicer for its expenses and
(y) that the expenses will be recoverable by it through Liquidation Proceeds or
Insurance Proceeds.

         A mortgage pool insurance policy (and most Primary Insurance
Policies)will likely not insure against loss sustained by reason of a default
arising from, among other things, (1) fraud or negligence in the origination or
servicing of a mortgage loan, including misrepresentation by the mortgagor, the
Seller or other persons involved in the origination thereof, or (2) failure to
construct a mortgaged property in accordance with plans and specifications.
Depending upon the nature of the event, a breach of representation made by a
Seller may also have occurred. This breach, if it materially and adversely
affects the interests of securityholders and cannot be cured, would give rise to
a purchase obligation on the part of the Seller, as more fully described under
"The Mortgage Pools--Representations by Sellers." However, this event would not
give rise to a breach of a representation and warranty or a purchase obligation
on the part of the depositor or master servicer.

         The original amount of coverage under each mortgage pool insurance
policy will be reduced over the life of the related series of securities by the
aggregate dollar amount of claims paid less the aggregate of the net amounts
realized by the pool insurer upon disposition of all foreclosed properties. The
amount of claims paid includes expenses incurred by the master servicer, special
servicer or subservicer as well as accrued interest on delinquent mortgage loans
to the date of payment of the claim. Accordingly, if aggregate net claims paid
under any mortgage pool insurance policy reach the original policy limit,
coverage under that mortgage pool insurance policy will be exhausted and any
further losses will be borne by holders of the related series of securities. In
addition, unless the master servicer could determine that an advance in respect
of a delinquent mortgage loan would be recoverable to it from the proceeds of
the liquidation of the mortgage loan or otherwise, the master servicer would not
be obligated to make an advance respecting the delinquency since the advance
would not be ultimately recoverable to it from either the mortgage pool
insurance policy or from any other related source. See "Description of the
Securities--Advances."

         Since each mortgage pool insurance policy will require that the
property subject to a defaulted mortgage loan be restored to its original
condition prior to claiming against the pool insurer, the policy will not
provide coverage against hazard losses. As set forth under "Primary Mortgage
Insurance, Hazard Insurance; Claims Thereunder," the hazard policies covering
the mortgage loans typically exclude from coverage physical damage resulting
from a number of causes and, even when the damage is covered, may afford
recoveries which are significantly less than full replacement cost of the
losses. Further, no coverage in respect of Special Hazard Losses, Fraud Losses
or Bankruptcy Losses will cover all risks, and the amount of the coverage will
be limited. See "Special Hazard Insurance Policies" below. As a result, some
hazard risks will not be insured against and will therefore be borne by the
related securityholders.

                                     - 54 -


LETTER OF CREDIT

         If any component of credit enhancement as to the offered securities of
any series is to be provided by a letter of credit, a bank will deliver to the
related trustee an irrevocable letter of credit. The letter of credit may
provide direct coverage with respect to the mortgage loans. The bank that
delivered the letter of credit, as well as the amount available under the letter
of credit with respect to each component of credit enhancement, will be
specified in the applicable prospectus supplement. If so specified in the
related prospectus supplement, the letter of credit may permit draws only in the
event of some types of losses and shortfalls. The letter of credit may also
provide for the payment of advances which the master servicer would be obligated
to make with respect to delinquent monthly mortgage payments. The amount
available under the letter of credit will, in all cases, be reduced to the
extent of the unreimbursed payments thereunder and may otherwise be reduced as
described in the related prospectus supplement. The letter of credit will expire
on the expiration date set forth in the related prospectus supplement, unless
earlier terminated or extended in accordance with its terms.

SPECIAL HAZARD INSURANCE POLICIES

         Any special hazard insurance policy covering Special Hazard Losses
obtained by the depositor for a trust fund will be issued by the insurer named
in the applicable prospectus supplement. Each special hazard insurance policy
will, subject to limitations described below, protect holders of the related
series of securities from Special Hazard Losses. See "Primary Mortgage
Insurance, Hazard Insurance; Claims Thereunder." However, a special hazard
insurance policy will not cover losses occasioned by war, civil insurrection,
some governmental actions, errors in design, faulty workmanship or materials
(except under some circumstances), nuclear reaction, chemical contamination,
waste by the mortgagor and other risks. Aggregate claims under a special hazard
insurance policy will be limited to the amount set forth in the related
prospectus supplement and will be subject to reduction as described in the
related prospectus supplement. A special hazard insurance policy will provide
that no claim may be paid unless hazard and, if applicable, flood insurance on
the property securing the mortgage loan has been kept in force and other
protection and preservation expenses have been paid by the master servicer.

         Subject to the foregoing limitations, a special hazard insurance policy
will provide that, where there has been damage to property securing a foreclosed
mortgage loan (title to which has been acquired by the insured) and to the
extent the damage is not covered by the hazard insurance policy or flood
insurance policy, if any, maintained by the mortgagor or the master servicer,
special servicer or the subservicer, the insurer will pay the lesser of (1) the
cost of repair or replacement of the property or (2) upon transfer of the
property to the insurer, the unpaid principal balance of the mortgage loan at
the time of acquisition of the property by foreclosure or deed in lieu of
foreclosure, plus accrued interest at the mortgage rate to the date of claim
settlement and expenses incurred by the master servicer, special servicer or
subservicer with respect to the property. If the property is transferred to a
third party in a sale approved by the issuer of the special hazard insurance
policy, the amount that the issuer will pay will be the amount under (ii) above
reduced by the net proceeds of the sale of the property. No claim may be validly
presented under the special hazard insurance policy unless hazard insurance on
the



                                     - 55 -


property securing a defaulted mortgage loan has been kept in force and other
reimbursable protection, preservation and foreclosure expenses have been paid
(all of which must be approved in advance by the issuer of the special hazard
insurance policy). If the unpaid principal balance plus accrued interest and
expenses is paid by the insurer, the amount of further coverage under the
related special hazard insurance policy will be reduced by that amount less any
net proceeds from the sale of the property. Any amount paid as the cost of
repair of the property will further reduce coverage by that amount. Restoration
of the property with the proceeds described under (1) above will satisfy the
condition under each mortgage pool insurance policy that the property be
restored before a claim under the mortgage pool insurance policy may be validly
presented with respect to the defaulted mortgage loan secured by the property.
The payment described under (2) above will render presentation of a claim in
respect of the mortgage loan under the related mortgage pool insurance policy
unnecessary. Therefore, so long as a mortgage pool insurance policy remains in
effect, the payment by the insurer under a special hazard insurance policy of
the cost of repair or of the unpaid principal balance of the related mortgage
loan plus accrued interest and expenses will not affect the total Insurance
Proceeds paid to securityholders, but will affect the relative amounts of
coverage remaining under the related special hazard insurance policy and
mortgage pool insurance policy.

         As and to the extent set forth in the applicable prospectus supplement,
coverage in respect of Special Hazard Losses for a series of securities may be
provided, in whole or in part, by a type of instrument other than a special
hazard insurance policy or by means of a special hazard representation of the
Seller or the depositor.

         If so provided in the related prospectus supplement, the depositor will
deposit or cause to be deposited in a reserve fund account any combination of
cash, one or more irrevocable letters of credit or one or more Permitted
Investments in specified amounts, or any other instrument satisfactory to the
relevant Rating Agency or Agencies, which will be applied and maintained in the
manner and under the conditions specified in the prospectus supplement. In the
alternative or in addition to the deposit, to the extent described in the
related prospectus supplement, a reserve fund may be funded through application
of all or a portion of amounts otherwise payable on any related subordinate
securities, from the retained interest of the depositor or otherwise. To the
extent that the funding of the reserve fund is dependent on amounts otherwise
payable on related subordinate securities, any retained interest of the
depositor or other cash flows attributable to the related mortgage loans or on
reinvestment income, the reserve fund may provide less coverage than initially
expected if the cash flows or reinvestment income on which the funding is
dependent are lower than anticipated. In addition, with respect to any series of
securities as to which credit enhancement includes a letter of credit, if so
specified in the related prospectus supplement, if specified conditions are met,
the remaining amount of the letter of credit may be drawn by the trustee and
deposited in a reserve fund. Amounts in a reserve fund may be distributed to
securityholders, or applied to reimburse the master servicer for outstanding
advances, or may be used for other purposes, in the manner and to the extent
specified in the related prospectus supplement. The related prospectus
supplement will disclose whether a reserve fund is part of the related trust
fund. If set forth in the related prospectus supplement, a reserve fund may
provide coverage to more than one series of securities.

                                     - 56 -


         In connection with the establishment of any reserve fund, the reserve
fund will be structured so that the trustee will have a perfected security
interest for the benefit of the securityholders in the assets in the reserve
fund. However, to the extent that the depositor, any affiliate thereof or any
other entity has an interest in any reserve fund, in the event of the
bankruptcy, receivership or insolvency of that entity, there could be delays in
withdrawals from the reserve fund and corresponding payments to the
securityholders which could adversely affect the yield to investors on the
related securities.

         Amounts deposited in any reserve fund for a series will be invested in
Permitted Investments by, or at the direction of, and for the benefit of the
master servicer or any other person named in the related prospectus supplement.

CASH FLOW AGREEMENTS

         If so provided in the related prospectus supplement, the trust fund may
include guaranteed investment contracts pursuant to which moneys held in the
funds and accounts established for the related series will be invested at a
specified rate. The principal terms of a guaranteed investment contract or other
cash flow agreement, and the identity of the obligor, will be described in the
prospectus supplement for a series of notes.

MAINTENANCE OF CREDIT ENHANCEMENT

         To the extent that the applicable prospectus supplement does not
expressly provide for alternative credit enhancement arrangements in lieu of
some or all of the arrangements mentioned below, the following paragraphs shall
apply.

         If a financial guaranty insurance policy has been obtained for a series
of securities, the master servicer will be obligated to exercise reasonable
efforts to keep the financial guaranty insurance policy in full force and effect
throughout the term of the applicable pooling and servicing agreement, unless
coverage thereunder has been exhausted through payment of claims or until the
financial guaranty insurance policy is replaced in accordance with the terms of
the applicable pooling and servicing agreement. The master servicer will agree
to pay the premiums for each financial guaranty insurance policy on a timely
basis. In the event the insurer ceases to be a qualified insurer as described in
the related prospectus supplement, or fails to make a required payment under the
related financial guaranty insurance policy, the master servicer will have no
obligation to replace the insurer. Any losses associated with any reduction or
withdrawal in rating by an applicable Rating Agency shall be borne by the
related securityholders.

         If a mortgage pool insurance policy has been obtained for a series of
securities, the master servicer will be obligated to exercise reasonable efforts
to keep the mortgage pool insurance policy (or an alternate form of credit
support) in full force and effect throughout the term of the applicable pooling
and servicing agreement or servicing agreement, unless coverage thereunder has
been exhausted through payment of claims or until the mortgage pool insurance
policy is replaced in accordance with the terms of the applicable pooling and
servicing agreement or servicing agreement. The master servicer will agree today
the premiums for each



                                     - 57 -


mortgage pool insurance policy on a timely basis. In the event the pool insurer
ceases to be a qualified insurer because it ceases tone qualified by law to
transact pool insurance business or coverage is terminated for any reason other
than exhaustion of the coverage, the master servicer will use reasonable efforts
to obtain from another qualified insurer replacement insurance policy comparable
to the mortgage pool insurance policy with a total coverage equal to the then
outstanding coverage of the mortgage pool insurance policy, provided that, if
the cost of the replacement policy is greater than the cost of the mortgage pool
insurance policy, the coverage of the replacement policy will, unless otherwise
agreed to by the depositor, be reduced to a level such that its premium rate
does not exceed the premium rate on the mortgage pool insurance policy. In the
event that the pool insurer ceases to be a qualified insurer because it ceases
to be approved as an insurer by Freddie Mac, Fannie Mae or any successor entity,
the master servicer will be obligated to review, not less often than monthly,
the financial condition of the pool insurer with a view toward determining
whether recoveries under the mortgage pool insurance policy are jeopardized for
reasons related to the financial condition of the pool insurer. If the master
servicer determines that recoveries are so jeopardized, it will be obligated to
exercise its best reasonable efforts to obtain from another qualified insurer a
replacement insurance policy as described above, subject to the same cost limit.
Any losses associated with any reduction or withdrawal in rating by an
applicable Rating Agency shall be borne by the related securityholders.

         If a letter of credit or alternate form of credit enhancement has been
obtained for a series of securities, the master servicer will be obligated to
exercise reasonable efforts cause to be kept or to keep the letter of credit (or
an alternate form of credit support) in full force and effect throughout the
term of the applicable pooling and servicing agreement or indenture, unless
coverage thereunder has been exhausted through payment of claims or otherwise,
or substitution therefor is made as described below under "Reduction or
Substitution of Credit Enhancement." Unless otherwise specified in the
applicable prospectus supplement, if a letter of credit obtained for a series of
securities is scheduled to expire prior to the date the final distribution on
the securities is made and coverage under the letter of credit has not been
exhausted and no substitution has occurred, the trustee will draw the amount
available under the letter of credit and maintain the amount in trust for the
securityholders.

         In lieu of the master servicer's obligation to maintain a financial
guaranty insurance policy, mortgage pool insurance policy or letter of credit as
provided above, the master servicer may obtain a substitute financial guaranty
insurance policy, mortgage pool insurance policy or letter of credit. If the
master servicer obtains a substitute, it will maintain and keep the substitute
in full force and effect as provided in this prospectus. Prior to its obtaining
any substitute financial guaranty insurance policy, mortgage pool insurance
policy or letter of credit, the master servicer will obtain written confirmation
from the Rating Agency or Agencies that rated the related series of securities
that the substitution of the financial guaranty insurance policy, mortgage pool
insurance policy or letter of credit for the existing credit enhancement will
not adversely affect the then-current ratings assigned to the securities by the
Rating Agency or Agencies.

         If a special hazard insurance policy has been obtained for a series of
securities, the master servicer will also be obligated to exercise reasonable
efforts to maintain and keep the policy in full force and effect throughout the
term of the applicable pooling and servicing agreement



                                     - 58 -


or servicing agreement, unless coverage thereunder has been exhausted through
payment of claims or otherwise or substitution therefor is made as described
below under "--Reduction or Substitution of Credit Enhancement." If coverage for
Special Hazard Losses takes the form of a special hazard insurance policy, the
policy will provide coverage against risks of the type described in this
prospectus under "Description of Credit Enhancement--Special Hazard Insurance
Policies." The master servicer may obtain a substitute policy for the existing
special hazard insurance policy if prior to the substitution the master servicer
obtains written confirmation from the Rating Agency or Agencies that rated the
related securities that the substitution shall not adversely affect the
then-current ratings assigned to the securities by the Rating Agency or
Agencies.

         The master servicer, on behalf of itself, the trustee and
securityholders, will provide the trustee information required for the trustee
to draw under the letter of credit and will present claims to each pool insurer,
to the issuer of each special hazard insurance policy, and, in respect of
defaulted mortgage loans for which there is no subservicer, to each primary
insurer and take any reasonable steps as are necessary to permit recovery under
the letter of credit, insurance policies or comparable coverage respecting
defaulted mortgage loans or mortgage loans which are the subject of a bankruptcy
proceeding. As set forth above, all collections by the master servicer under any
mortgage pool insurance policy or any Primary Insurance Policy and, where the
related property has not been restoration special hazard insurance policy, are
to be deposited in the related certificate Account, subject to withdrawal as
described above. All draws under any letter of credit are also to be deposited
in the related Certificate account. In those cases in which a mortgage loan is
serviced by a subservicer, the subservicer, on behalf of itself, the trustee and
the securityholders will present claims to the primary insurer, and all paid
claims shall initially be deposited in a subservicing account that generally
meets the requirements for the Certificate Account prior to being delivered to
the master servicer for deposit in the related Certificate Account.

         If any property securing a defaulted mortgage loan is damaged and
proceeds, if any, from the related hazard insurance policy or any applicable
special hazard insurance policy are insufficient to restore the damaged property
to a condition sufficient to permit recovery under any financial guaranty
insurance policy, mortgage pool insurance policy, letter of credit or any
related Primary Insurance Policy, the master servicer is not required to expend
its own funds to restore the damaged property unless it determines (1) that the
restoration will increase the proceeds to one or more classes of securityholders
on liquidation of the mortgage loan after reimbursement of the master servicer
for its expenses and (2) that the expenses will be recoverable by it through
liquidation Proceeds or Insurance Proceeds. If recovery under any financial
guaranty insurance policy, mortgage pool insurance policy, letter of credit or
any related Primary Insurance Policy is not available because the master
servicer has been unable to make the above determinations, has made the
determinations incorrectly or recovery is not available for any other reason,
the master servicer is nevertheless obligated to follow the normal practices and
procedures (subject to the preceding sentence) as it deems necessary or
advisable to realize upon the defaulted mortgage loan and in the event the
determination has been incorrectly made, is entitled to reimbursement of its
expenses in connection with the restoration.

                                     - 59 -


REDUCTION OR SUBSTITUTION OF CREDIT ENHANCEMENT

         The amount of credit support provided pursuant to any form of credit
enhancement may be reduced. The amount available pursuant to any form of credit
enhancement will be subject to periodic reduction in accordance with a schedule
or formula on a nondiscretionary basis pursuant to the terms of the related
pooling and servicing agreement or indenture. Additionally, in most cases, the
form of credit support (and any replacements therefor) may be replaced, reduced
or terminated, and the formula used in calculating the amount of coverage with
respect to Bankruptcy Losses, Special Hazard Losses or Fraud Losses may be
changed, without the consent of the securityholders, upon the written assurance
from each applicable Rating Agency that the then-current rating of the related
series of securities will not be adversely affected. Furthermore, in the event
that the credit rating of any obligor under any applicable credit enhancement is
downgraded, the credit rating(s) of the related series of securities may be
downgraded to a corresponding level, and, the master servicer will not be
obligated to obtain replacement credit support in order to restore the rating(s)
of the related series of securities. The master servicer will also be permitted
to replace the credit support with other credit enhancement instruments issued
by obligors whose credit ratings are equivalent to the downgraded level and in
lower amounts which would satisfy the downgraded level, provided that the
then-current rating(s) of the related series of securities are maintained. Where
the credit support is in the form of a reserve fund, a permitted reduction in
the amount of credit enhancement will result in a release of all or a portion of
the assets in the reserve fund to the depositor, the master servicer or the
other person that is entitled thereto. Any assets so released will not be
available for distributions in future periods.

              OTHER FINANCIAL OBLIGATIONS RELATED TO THE SECURITIES

DERIVATIVES

         The trust fund may include one or more derivative instruments, as
described in this section. All derivative instruments included in any trust fund
will be used only in a manner that reduces or alters risk resulting from the
mortgage loans or other assets in the pool, and only in a manner such that the
return on the offered securities will be based primarily on the performance of
the mortgage loans or other assets in the pool. Derivative instruments may
include 1) interest rate swaps (or caps, floors and collars) and yield
supplement agreements as described below, 2) currency swaps, 3) market value
swaps that are referenced to the value of one or more of the mortgage loans or
other assets included in the trust fund or to a class of offered securities and
that are used solely in conjunction with auctions, and 4) credit default swaps
that protect against defaults and losses on mortgage loans or other assets
included in the trust fund or to a class of offered securities as described
below.

         An interest rate swap is an agreement between two parties to exchange a
stream of interest payments on an agreed hypothetical or "notional" principal
amount. No principal amount is exchanged between the counterparties to an
interest rate swap. In the typical swap, one party agrees to pay a fixed rate on
a notional principal amount, while the counterparty pays a floating rate based
on one or more reference interest rates including the London Interbank Offered
Rate, or LIBOR, a specified bank's prime rate or U.S. Treasury Bill rates.
Interest rate swaps also permit counterparties to exchange a floating rate
obligation based upon one reference



                                     - 60 -


interest rate, such as LIBOR, for a floating rate obligation based upon another
referenced interest rate, such as U.S. Treasury Bill rates. An interest rate
cap, collar or floor is an agreement where the counterparty agrees to make
payments representing interest on a notional principal amount when a specified
reference interest rate is above a strike rate, outside of a range of strike
rates, or below a strike rate as specified in the agreement, generally in
exchange for a fixed amount paid to the counterparty at the time the agreement
is entered into. A yield supplement agreement is a type of cap agreement, and is
substantially similar to a cap agreement as described above.

         The trustee on behalf of a trust fund may enter into interest rate
swaps, caps, floors and collars, or yield supplement agreements, to minimize the
risk to securityholders from adverse changes in interest rates or to provide
supplemental credit support. Cap agreements and yield supplement agreements may
be entered into to supplement the interest rate or other rates available to make
interest payments on one or more classes of the securities of any series.

         A market value swap might be used in a structure where the pooled
assets are hybrid ARMs, or mortgage loans that provide for a fixed rate period
and then convert by their terms to adjustable rate loans. Such a structure might
provide that at a specified date near the end of the fixed rate period, the
investors must tender their securities to the trustee who will then transfer the
securities to other investors in a mandatory auction procedure. The market value
swap would ensure that the original investors would receive at least par at the
time of tender, by covering any shortfall between par and the then current
market value of their securities.

         Derivatives may include credit default swaps where credit enhancement
is provided in the form of a swap agreement. Credit default swaps will only be
used to protect against defaults and losses on mortgage loans or other assets
included in the trust fund or allocated to a class of offered securities. The
terms of credit derivatives and any other derivative product agreement and any
counterparties will be described in the accompanying prospectus supplement.

         Any derivative contracts will be documented based upon the standard
forms provided by the International Swaps and Derivatives Association, or ISDA.
These forms generally consist of an ISDA master agreement, a schedule to the
master agreement, and a confirmation, although in some cases the schedule and
confirmation will be combined in a single document and the standard ISDA master
agreement will be incorporated therein by reference. Standard ISDA definitions
also will be incorporated by reference. Each confirmation will provide for
payments to be made by the derivative counterparty to the trust, and in some
cases by the trust to the derivative counterparty, generally based upon
specified notional amounts and upon differences between specified interest rates
or values. For example, the confirmation for an interest rate cap agreement will
contain a schedule of fixed interest rates, generally referred to as strike
rates, and a schedule of notional amounts, for each distribution date during the
term of the interest rate cap agreement. The confirmation also will specify a
reference rate, generally a floating or adjustable interest rate, and will
provide that payments will be made by the derivative counterparty to the trust
on each distribution date, based on the notional amount for that distribution
date and the excess, if any, of the specified reference rate over the strike
rate for that distribution date.

         In the event of the withdrawal of the credit rating of a derivative
counterparty or the downgrade of such credit rating below levels specified in
the derivative contract (where the derivative contract is relevant to the
ratings of the offered securities, such levels generally are set



                                     - 61 -


by the rating
agencies rating the offered securities), the derivative counterparty may be
required to post collateral for the performance of its obligations under the
derivative contract, or to take certain other measures intended to assure
performance of those obligations. Posting of collateral will be documented using
the ISDA Credit Support Annex.

         There can be no assurance that the trustee will be able to enter into
derivatives at any specific time or at prices or on other terms that are
advantageous. In addition, although the terms of the derivatives may provide for
termination under various circumstances, there can be no assurance that the
trustee will be able to terminate a derivative when it would be economically
advantageous to the trust fund to do so.

PURCHASE OBLIGATIONS

         Some types of trust assets and some classes of securities of any
series, as specified in the related prospectus supplement, may be subject to a
purchase obligation that would become applicable on one or more specified dates,
or upon the occurrence of one or more specified events, or on demand made by or
on behalf of the applicable securityholders. A purchase obligation may be in the
form of a conditional or unconditional purchase commitment, liquidity facility,
remarketing agreement, maturity guaranty, put option or demand feature.

         A purchase commitment is a contractual obligation of an obligor to
purchase either specified trust assets or classes of securities of any series,
on one or more specified dates, or upon the occurrence of one or more specified
events. A liquidity facility is an obligation of a lender to advance funds,
which may be used to purchase specified trust assets from the issuing entity on
one or more specified dates, or upon the occurrence of one or more specified
events. A remarketing agreement is an obligation of a remarketing agent to sell
specified trust assets on behalf of the issuing entity on one or more specified
dates, or upon the occurrence of one or more specified events, and may include
an obligation of the remarketing agent to cover any shortfall between the sale
proceeds and a specified level. A maturity guaranty is a contractual obligation
of an obligor to purchase either specified trust assets or classes of securities
of any series, on one or more specified maturity dates. A put option is a
contractual obligation of an obligor to purchase either specified trust assets
or classes of securities of any series upon the exercise of the option by a
specified party, on one or more specified dates, or upon the occurrence of one
or more specified events. A demand feature is a contractual obligation of an
obligor to purchase either specified trust assets or classes of securities of
any series upon demand made by a specified party, on one or more specified
dates, or upon the occurrence of one or more specified events.

         The terms and conditions of each purchase obligation, including the
purchase price, timing and payment procedure, will be described in the
accompanying prospectus supplement. A purchase obligation relating to trust
assets may apply to those trust assets or to the related securities. Each
purchase obligation may be a secured or unsecured obligation of the provider
thereof, which may include a bank or other financial institution or an insurance
company. Each purchase obligation will be evidenced by an instrument delivered
to the trustee for the benefit of the applicable securityholders of the related
series. As specified in the accompanying prospectus supplement, each purchase
obligation relating to trust assets will be payable solely to the trustee



                                     - 62 -


for the benefit of the securityholders of the related series. Other purchase
obligations may be payable to the trustee or directly to the holders of the
securities to which that obligation relate.

                  PRIMARY MORTGAGE INSURANCE, HAZARD INSURANCE;
                                CLAIMS THEREUNDER

GENERAL

         The mortgaged property with respect to each mortgage loan will be
required to be covered by a hazard insurance policy and, if required as
described below, a Primary Insurance Policy. The following is only a brief
description of these insurance policies and does not purport to summarize or
describe all of the provisions of these policies. The insurance is subject to
underwriting and approval of individual mortgage loans by the respective
insurers.

PRIMARY MORTGAGE INSURANCE POLICIES

         In a securitization of single family loans, single family loans
included in the related mortgage pool having a loan-to-value ratio at
origination of over 80% (or other percentage as described in the related
prospectus supplement) may be required by the depositor to be covered by a
Primary Insurance Policy. The Primary Insurance Policy will insure against
default on a mortgage loan as to at least the principal amount thereof exceeding
75% of the Value of the related mortgaged property (or other percentage as
described in the related prospectus supplement) at origination of the mortgage
loan, unless and until the principal balance of the mortgage loan is reduced to
a level that would produce a loan-to-value ratio equal to or less than at least
80% (or other percentage as described in the prospectus supplement). The
depositor will represent and warrant that, to the best of the depositor's
knowledge, mortgage loans of this type are so covered. This type of mortgage
loan will not be considered to be an exception to the foregoing standard if no
Primary Insurance Policy was obtained at origination but the mortgage loan has
amortized to below the above loan-to-value ratio percentage as of the applicable
cut-off date. Mortgage loans which are subject to negative amortization will
only be covered by a Primary Insurance Policy if the coverage was so required
upon their origination, notwithstanding that subsequent negative amortization
may cause the mortgage loan's loan-to-value ratio, based on the then-current
balance, to subsequently exceed the limits which would have required the
coverage upon their origination. Multifamily, commercial and mixed-use loans
will not be covered by a Primary Insurance Policy, regardless of the related
loan-to-value ratio.

         While the terms and conditions of the Primary Insurance Policies issued
by a primary insurer will differ from those in Primary Insurance Policies issued
by other primary insurers, each Primary Insurance Policy will in general cover
the Primary Insurance Covered Loss. The primary insurer generally will be
required to pay:

         o        the insured percentage of the Primary Insurance Covered Loss;

         o        the entire amount of the Primary Insurance Covered Loss, after
                  receipt by the primary insurer of good and merchantable title
                  to, and possession of, the mortgaged property; or

                                     - 63 -


         o        at the option of the primary insurer, the sum of the
                  delinquent monthly payments plus any advances made by the
                  insured, both to the date of the claim payment and,
                  thereafter, monthly payments in the amount that would have
                  become due under the mortgage loan if it had not been
                  discharged plus any advances made by the insured until the
                  earlier of (1) the date the mortgage loan would have been
                  discharged in full if the default had not occurred or (2) an
                  approved sale.

         As conditions precedent to the filing or payment of a claim under a
Primary Insurance Policy, in the event of default by the mortgagor, the insured
will typically be required, among other things, to:

         o        advance or discharge (1) hazard insurance premiums and (2) as
                  necessary and approved in advance by the primary insurer, real
                  estate taxes, protection and preservation expenses and
                  foreclosure and related costs;

         o        in the event of any physical loss or damage to the mortgaged
                  property, have the mortgaged property restored to at least its
                  condition at the effective date of the Primary Insurance
                  Policy (ordinary wear and tear excepted); and

         o        tender to the primary insurer good and merchantable title to,
                  and possession of, the mortgaged property.

         For any single family loan for which the coverage is required under the
standard described above, the master servicer will maintain or cause each
subservicer to maintain, as the case may be, in full force and effect and to the
extent coverage is available a Primary Insurance Policy with regard to each
single family loan, provided that the Primary Insurance Policy was in place as
of the cut-off date and the depositor had knowledge of the Primary Insurance
Policy. In the event the depositor gains knowledge that as of the Closing Date,
a mortgage loan which required a Primary Insurance Policy did not have one, then
the master servicer is required to use reasonable efforts to obtain and maintain
a Primary Insurance Policy to the extent that the policy is obtainable at a
reasonable price. The master servicer or the Seller will not cancel or refuse to
renew a Primary Insurance Policy in effect at the time of the initial issuance
of a series of securities that is required to be kept in force under the
applicable pooling and servicing agreement or indenture unless the replacement
Primary Insurance Policy for the canceled or non-renewed policy is maintained
with an insurer whose claims-paying ability is acceptable to the Rating Agency
or Agencies that rated the series of securities for mortgage pass-through
certificates having a rating equal to or better than the highest then-current
rating of any class of the series of securities. For further information
regarding the extent of coverage under any mortgage pool insurance policy or
primary Insurance Policy, see "Description of Credit--Enhancement Mortgage Pool
Insurance Policies."

HAZARD INSURANCE POLICIES

         The terms of the mortgage loans require each mortgagor to maintain a
hazard insurance policy for their mortgage loan. Additionally, the pooling and
servicing agreement or servicing agreement will require the master servicer to
cause to be maintained for each mortgage loan a hazard insurance policy
providing for no less than the coverage of the standard form of fire



                                     - 64 -


insurance policy with extended coverage customary in the state in which the
property is located. The coverage generally will be in an amount equal to the
lesser of the principal balance owing on the mortgage loan or 100% of the
insurable value of the improvements securing the mortgage loan except that, if
generally available, the coverage must not be less than the minimum amount
required under the terms thereof to fully compensate for any damage or loss on a
replacement cost basis. The ability of the master servicer to ensure that hazard
insurance proceeds are appropriately applied may be dependent on its being named
as an additional insured under any hazard insurance policy and under any flood
insurance policy referred to below, or upon the extent to which information in
this regard is furnished to the master servicer by mortgagors or subservicers.

         As set forth above, all amounts collected by the master servicer under
any hazard policy (except for amounts to be applied to the restoration or repair
of the mortgaged property or released to the mortgagor in accordance with
teamster servicer's normal servicing procedures) will be deposited in the
related Certificate Account. The pooling and servicing agreement or servicing
agreement will provide that the master servicer may satisfy its obligation to
cause hazard policies to be maintained by maintaining a blanket policy insuring
against losses on the mortgage loans. If the blanket policy contains a
deductible clause, the master servicer will deposit in the applicable
certificate Account all sums which would have been deposited therein but for the
clause.

         In general, the standard form of fire and extended coverage policy
covers physical damage to or destruction of the improvements on the property by
fire, lightning, explosion, smoke, windstorm, hail, riot, strike and civil
commotion, subject to the conditions and exclusions specified in each policy.
Although the policies relating to the mortgage loans will be underwritten by
different insurers under different state laws in accordance with different
applicable state forms and therefore will not contain identical terms and
conditions, the basic terms thereof are dictated by respective state laws, and
most of these policies typically do not cover any physical damage resulting from
the following: war, revolution, governmental actions, floods and other
water-related causes, earth movement (including earthquakes, landslides and
mudflows), nuclear reactions, wet or dry rot, vermin, rodents, insects or
domestic animals, theft and, depending on the case, vandalism. The foregoing
list is merely indicative of the kinds of uninsured risks and is not intended to
be all-inclusive. Where the improvements securing a mortgage loan are located in
a federally designated flood area at the time of origination of the mortgage
loan, the pooling and servicing agreement or servicing agreement requires the
master servicer to cause to be maintained for this mortgage loan, flood
insurance (to the extent available) in an amount equal in general to the lesser
of the amount required to compensate for any loss or damage on a replacement
cost basis or the maximum insurance available under the federal flood insurance
program.

         The hazard insurance policies covering the mortgaged properties
typically contain a co-insurance clause which in effect requires the insured at
all times to carry insurance of a specified percentage (generally 80% to 90%) of
the full replacement value of the improvements on the property in order to
recover the full amount of any partial loss. If the insured's coverage falls
below this specified percentage, the clause generally provides that the
insurer's liability in the event of partial loss does not exceed the greater of
(1) the replacement cost of the improvements damaged or destroyed less physical
depreciation or (2) the proportion of the loss



                                     - 65 -


as the amount of insurance carried bears to the specified percentage of the full
replacement cost of the improvements.

         Since the amount of hazard insurance that mortgagors are required to
maintain on the improvements securing the mortgage loans may decline as the
principal balances of the related mortgage loans decrease, and since residential
properties have historically appreciated in value over time, hazard insurance
proceeds could be insufficient to restore fully the damaged property in the
event of a partial loss. See "Description of Credit Enhancement--Special Hazard
Insurance Policies" for a description of the limited protection afforded by any
special hazard insurance policy against losses occasioned by hazards which are
otherwise uninsured against (including losses caused by the application of the
co-insurance clause described in the preceding paragraph).

         Under the terms of the mortgage loans, mortgagors are generally
required to present claims to insurers under hazard insurance policies
maintained on the mortgaged properties. The master servicer, on behalf of the
trustee and securityholders, is obligated to present claims under any special
hazard insurance policy and any blanket insurance policy insuring against hazard
losses on the mortgaged properties. However, the ability of the master servicer
to present the claims is dependent upon the extent to which information in this
regard is furnished to the master servicer or the subservicers by mortgagors.

FHA INSURANCE

         The FHA is responsible for administering various federal programs,
including mortgage insurance, authorized under The Housing Act and the United
States Housing Act of 1937, as amended.

         There are two primary FHA insurance programs that are available for
multifamily mortgage loans. Sections 221(d)(3) and (d)(4) of the Housing Act
allow HUD to insure mortgage loans that are secured by newly constructed and
substantially rehabilitated multifamily rental projects. Section 244 of the
Housing Act provides for co-insurance of such mortgage loans made under Sections
221(d)(3) and (d)(4) by HUD/FHA and a HUD-approved co-insurer. Generally the
term of such a mortgage loan may be up to 40 years and the ratio of the loan
amount to property replacement cost can be up to 90%.

         Section 223(f) of the Housing Act allows HUD to insure mortgage loans
made for the purchase or refinancing of existing apartment projects which are at
least three years old. Section 244 also provides for co-insurance of mortgage
loans made under Section 223(f). Under Section 223(f), the loan proceeds cannot
be used for substantial rehabilitation work, but repairs may be made for up to,
in general, the greater of 15% of the value of the project or a dollar amount
per apartment unit established from time to time by HUD. In general the loan
term may not exceed 35 years and a loan to value ratio of no more than 85% is
required for the purchase of a project and 70% for the refinancing of a project.

         HUD has the option, in most cases, to pay insurance claims in cash or
in debentures issued by HUD. Presently, claims are being paid in cash, and
claims have not been paid in debentures since 1965. HUD debentures issued in
satisfaction of FHA insurance claims bear



                                     - 66 -


interest at the applicable HUD debenture interest rate. The master servicer will
be obligated to purchase a debenture issued in satisfaction of a defaulted FHA
insured mortgage loan serviced by it for an amount equal to the principal amount
of any the debenture.

         The master servicer will be required to take steps reasonably necessary
to keep FHA insurance in full force and effect.

VA MORTGAGE GUARANTY

         The Servicemen's Readjustment Act of 1944, as amended, permits a
veteran or, in some instances, his or her spouse, to obtain a mortgage loan
guaranty by the VA covering mortgage financing of the purchase of a one- to
four-family dwelling unit to be occupied as the veteran's home at an interest
rate not exceeding the maximum rate in effect at the time the loan is made, as
established by HUD. The program has no limit on the amount of a mortgage loan,
requires no down payment for the purchaser and permits the guaranty of mortgage
loans with terms, limited by the estimated economic life of the property, up to
30 years. The maximum guaranty that may be issued by the VA under this program
is 50% of the original principal amount of the mortgage loan up to a dollar
limit established by the VA. The liability on the guaranty is reduced or
increased pro rata with any reduction or increase in amount of indebtedness, but
in no event will the amount payable on the guaranty exceed the amount of the
original guaranty. Notwithstanding the dollar and percentage limitations of the
guaranty, a mortgagee will ordinarily suffer a monetary loss only when the
difference between the unsatisfied indebtedness and the proceeds of a
foreclosure sale of mortgaged premises is greater than the original guaranty as
adjusted. The VA may, at its option, and without regard to the guaranty, make
full payment to a mortgagee of the unsatisfied indebtedness on a mortgage upon
its assignment to the VA.

         Since there is no limit imposed by the VA on the principal amount of a
VA-guaranteed mortgage loan but there is a limit on the amount of the VA
guaranty, additional coverage under a Primary Mortgage Insurance Policy may be
required by the depositor for VA loans in excess of amounts specified by the VA.
The amount of the additional coverage will beset forth in the related prospectus
supplement. Any VA guaranty relating to Contracts underlying a series of
certificates will be described in the related prospectus supplement.

                                  THE DEPOSITOR

         The depositor, Impac Secured Assets Corp., was formed in the state of
Delaware in 1998, and is a wholly-owned subsidiary of Impac Funding Corporation.

                                 THE AGREEMENTS

GENERAL

         Each series of certificates will be issued pursuant to a pooling and
servicing agreement or other agreement specified in the related prospectus
supplement. In general, the parties to a pooling and servicing agreement will
include the depositor, the trustee, the master servicer and, in some cases, a
special servicer. However, a pooling and servicing agreement that relates to a
trust fund that includes mortgage securities may include a party solely
responsible for the administration of the mortgage securities, and a pooling and
servicing agreement that relates to a trust fund that consists solely of
mortgage securities may not include a master servicer, special servicer or other
servicer as a party. All parties to each pooling and servicing agreement under
which securities of a series are issued will be identified in the related
prospectus supplement. Each series of notes will be issued pursuant to an
indenture. The parties to each indenture will be the related Issuing Entity and
the trustee. The Issuing Entity will be created pursuant to an owner trust
agreement between the depositor and the owner trustee.

         Forms of the Agreements have been filed as exhibits to the registration
statement of which this prospectus is a part. However, the provisions of each
Agreement will vary depending upon the nature of the related securities and the
nature of the related trust fund. The following summaries describe provisions
that may appear in a pooling and servicing agreement with respect to a series of
certificates or in either the servicing agreement or indenture with respect to a
series of notes. The prospectus supplement for a series of securities will
describe any provision of the related Agreements that materially differs from
the description thereof set forth below. The depositor will provide a copy of
the Agreement (without exhibits) that relates to any series of securities
without charge upon written request of a holder of an offered security of the
series addressed to it at its principal executive offices specified in this
prospectus under "The Depositor". As to each series of securities, the related
agreements will be filed with the Commission in a current report on Form 8-K
following the issuance of the securities.


                                     - 69 -


CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR

         The pooling and servicing agreement or servicing agreement for each
series of securities will provide that the master servicer may not resign from
its obligations and duties except upon a determination that performance of the
duties is no longer permissible under applicable law or except (1) in connection
with a permitted transfer of servicing or (2) upon appointment of a successor
servicer reasonably acceptable to the trustee and upon receipt by the trustee of
letter from each Rating Agency generally to the effect that the resignation and
appointment will not, in and of itself, result in a downgrading of the
securities. No resignation will become effective until the trustee or a
successor servicer has assumed the master servicer's responsibilities, duties,
liabilities and obligations under the pooling and servicing agreement or
servicing agreement.

         Each pooling and servicing agreement and servicing agreement will also
provide that the master servicer, the depositor and their directors, officers,
employees or agents will not be under any liability to the trust fund or the
securityholders for any action taken or for refraining from the taking of any
action in good faith, or for errors in judgment, unless the liability which
would otherwise be imposed was by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties or by reason of reckless disregard
of obligations and duties. Each pooling and servicing agreement and servicing
agreement will further provide that the master servicer, the depositor, and any
director, officer, employee or agent of the master servicer or the depositor are
entitled to indemnification by the trust fund and will be held harmless against
any loss, liability or expense incurred in connection with any legal action
relating to the pooling and servicing agreement or servicing agreement or the
related series of securities, other than any loss, liability or expense related
to any specific mortgage loan or mortgage loans (except a loss, liability or
expense otherwise reimbursable pursuant to the pooling and servicing agreement)
and any loss, liability or expense incurred by reason of willful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of
reckless disregard of obligations and duties. In addition, each pooling and
servicing agreement and servicing agreement will provide that neither the master
servicer nor the depositor will be under any obligation to appear in, prosecute
or defend any legal or administrative action that is not incidental to its
respective duties under the pooling and servicing agreement or servicing
agreement and which in its opinion may involve it in any expense or liability.
The master servicer or the depositor may, however, in its discretion undertake
any action which it may deem necessary or desirable with respect to the pooling
and servicing agreement or servicing agreement and the rights and duties of the
parties to that agreement and the interests of the securityholders. The legal
expenses and costs of the action and any resulting liability will be expenses,
costs and liabilities of the trust fund, and the master servicer or the
depositor, as the case may be, will be entitled reimbursement from funds
otherwise distributable to securityholders.

         Any person into which the master servicer may be merged or
consolidated, any person resulting from any merger or consolidation to which the
master servicer is a party or any person succeeding to the business of the
master servicer will be the successor of the master servicer under the related
pooling and servicing agreement or servicing agreement, provided that (1) the
person is qualified to service mortgage loans on behalf of Fannie Mae or Freddie
Mac and (2) the merger, consolidation or succession does not adversely affect
the then-current ratings of the classes of securities of the related series that
have been rated. In addition, notwithstanding the prohibition on its
resignation, the master servicer may assign its rights under a pooling and


                                     - 70 -


servicing agreement or servicing agreement to any person to whom the master
servicer is transferring a substantial portion of its mortgage servicing
portfolio, provided clauses (1) and (2) above are satisfied and the person is
reasonably satisfactory to the depositor and the trustee. In the case of an
assignment, the master servicer will be released from its obligations under the
pooling and servicing agreement or servicing agreement, exclusive of liabilities
and obligations incurred by it prior to the time of the assignment.

EVENTS OF DEFAULT AND RIGHTS UPON EVENT OF DEFAULT

         POOLING AND SERVICING AGREEMENT

         Events of default under the pooling and servicing agreement in respect
of a series of certificates, unless otherwise specified in the prospectus
supplement, will include:

         o        any failure by the master servicer to make a required deposit
                  to the Certificate Account or, if the master servicer is so
                  required, to distribute to the holders of any class of
                  certificates of the series any required payment (other than a
                  Monthly Advance) which continues unremedied for 3 days (or
                  other time period described in the related prospectus
                  supplement) after the giving of written notice of the failure
                  to the master servicer by the trustee or the depositor, or to
                  the master servicer;.

         o        any failure by the master servicer duly to observe or perform
                  in any material respect any other of its covenants or
                  agreements in the pooling and servicing agreement with respect
                  to the series of certificates, which covenants and agreements
                  materially affect the rights of certificateholders of such
                  series, and which failure continues unremedied for a period of
                  60 days after the date on which written notice of such
                  failure, properly requiring the same to be remedied, shall
                  have been given to the master servicer by the trustee or the
                  depositor, or to the master servicer, the depositor and the
                  trustee by the holders of certificates evidencing not less
                  than 25% of the aggregate undivided interests (or, if
                  applicable, voting rights) in the related trust fund;

         o        events of insolvency, readjustment of debt, marshaling of
                  assets and liabilities or similar proceedings regarding the
                  master servicer and some actions by the master servicer
                  indicating its insolvency or inability to pay its obligations,
                  as specified in the related pooling and servicing agreement;
                  and

         o        any failure of the master servicer to make advances as
                  described in this prospectus under "Description of the
                  Securities--Advances";

         o        any assignment or delegation by the master servicer of its
                  rights and duties under the pooling and servicing agreement,
                  in contravention of the provisions permitting assignment and
                  delegation in the pooling and servicing agreement; and

         o        any other event of default as set forth in the pooling and
                  servicing agreement.


                                     - 71 -


Additional events of default will be described in the related prospectus
supplement. A default pursuant to the terms of any mortgage securities included
in any trust fund will not constitute an event of default under the related
pooling and servicing agreement.

         So long as an event of default remains unremedied, either the depositor
or the trustee may, and at the direction of the holders of certificates
evidencing not less than 51% of the aggregate undivided interests (or, if
applicable, voting rights) in the related trust fund the trustee shall, by
written notification to the master servicer and to the depositor or the trustee,
as applicable, terminate all of the rights and obligations of the master
servicer under the pooling and servicing agreement (other than any rights of the
master servicer as certificateholder) covering the trust fund and in and to the
mortgage loans and the proceeds thereof, whereupon the trustee or, upon notice
to the depositor and with the depositor's consent, its designee will succeed to
all responsibilities, duties and liabilities of the master servicer under the
pooling and servicing agreement (other than any obligation to purchase mortgage
loans) and will be entitled to similar compensation arrangements. In the event
that the trustee would be obligated to succeed the master servicer but is
unwilling so to act, it may appoint (or if it is unable so to act, it shall
appoint) or petition a court of competent jurisdiction for the appointment of,
an established mortgage loan servicing institution with a net worth of at least
$15,000,000 to act as successor to the master servicer under the pooling and
servicing agreement (unless otherwise set forth in the pooling and servicing
agreement). Pending an appointment, the trustee is obligated to act as master
servicer. The trustee and the successor may agree upon the servicing
compensation to be paid, which in no event may be greater than the compensation
to the initial master servicer under the pooling and servicing agreement.

         No certificateholder will have any right under a pooling and servicing
agreement to institute any proceeding with respect to the pooling and servicing
agreement unless (1) that holder previously gave the trustee written notice of a
default that is continuing, (2) the holders of certificates evidencing not less
than 25% of the aggregate undivided interests (or, if applicable, voting rights)
in the related trust fund requested the trustee in writing to institute the
proceeding in its own name as trustee, (3) the trustee receives reasonable
security or indemnity against the costs, expenses and liabilities that may be
incurred in or because of the proceeding and (4) the trustee for a reasonable
time after receipt of the request and indemnity has neglected or refused to
institute any proceeding.

         The holders of certificates representing at least 66% of the aggregate
undivided interests (or, if applicable, voting rights) evidenced by those
certificates affected by a default or event of default may waive the default or
event of default (other than a failure by the master servicer to make an
advance); provided, however, that (1) a default or event of default under the
first or fourth items listed under "Events of Default" above may be waived only
by all of the holders of certificates affected by the default or event of
default and (2) no waiver shall reduce in any manner the amount of, or delay the
timing of, payments received on mortgage loans which are required to be
distributed to, or otherwise materially adversely affect, any non-consenting
certificateholder.

         SERVICING AGREEMENT

         For a series of notes, a servicing default under the related servicing
agreement generally will include:

                                     - 72 -


         o        any failure by the master servicer to make a required deposit
                  to the Certificate Account or, if the master servicer is so
                  required, to distribute to the holders of any class of notes
                  or Equity Certificates of the series any required payment
                  which continues unremedied for 5 business days (or other
                  period of time described in the related prospectus supplement)
                  after the giving of written notice of the failure to the
                  master servicer by the trustee or the Issuing Entity;

         o        any failure by the master servicer duly to observe or perform
                  in any material respect any other of its covenants or
                  agreements in the servicing agreement with respect to the
                  series of securities which continues unremedied for 45 days
                  after the giving of written notice of the failure to the
                  master servicer by the trustee or the Issuing Entity;

         o        events of insolvency, readjustment of debt, marshaling of
                  assets and liabilities or similar proceedings regarding the
                  master servicer and some actions by the master servicer
                  indicating its insolvency or inability to pay its obligations,
                  as specified in the related servicing agreement; and

         o        any other servicing default as set forth in the servicing
                  agreement.

         So long as a servicing default remains unremedied, either the depositor
or the trustee may, by written notification to the master servicer and to the
Issuing Entity or the trustee or trust fund, as applicable, terminate all of the
rights and obligations of the master servicer under the servicing agreement
(other than any right of the master servicer as noteholder or as holder of the
Equity Certificates and other than the right to receive servicing compensation
and expenses for servicing the mortgage loans during any period prior to the
date of the termination), whereupon the trustee will succeed to all
responsibilities, duties and liabilities of the master servicer under the
servicing agreement (other than any obligation to purchase mortgage loans) and
will be entitled to similar compensation arrangements. In the event that the
trustee would be obligated to succeed the master servicer but is unwilling so to
act, it may appoint (or if it is unable so to act, it shall appoint) or petition
a court of competent jurisdiction for the appointment of an approved mortgage
servicing institution with a net worth of at least $15,000,000 to act as
successor to the master servicer under the servicing agreement (unless otherwise
set forth in the servicing agreement). Pending the appointment, the trustee is
obligated to act in the capacity. The trustee and the successor may agree upon
the servicing compensation to be paid, which in no event may be greater than the
compensation to the initial master servicer under the servicing agreement.

         INDENTURE

         For a series of notes, an event of default under the indenture
generally will include:

         o        a default for five days or more (or other period of time
                  described in the related prospectus supplement) in the payment
                  of any principal of or interest on any note of the series;

                                     - 73 -


         o        failure to perform any other covenant of the depositor or the
                  trust fund in the indenture which continues for a period of
                  thirty days after notice thereof is given in accordance with
                  the procedures described in the related prospectus supplement;

         o        any representation or warranty made by the depositor or the
                  trust fund in the indenture or in any certificate or other
                  writing delivered pursuant thereto or in connection therewith
                  with respect to or affecting the series having been incorrect
                  in a material respect as of the time made, and the breach is
                  not cured within thirty days after notice thereof is given in
                  accordance with the procedures described in the related
                  prospectus supplement;

         o        events of bankruptcy, insolvency, receivership or liquidation
                  of the depositor or the trust fund, as specified in the
                  indenture; or

         o        any other event of default provided with respect to notes of
                  that series.

If an event of default with respect to the notes of any series at the time
outstanding occurs and is continuing, the trustee or the holders of a majority
of the then aggregate outstanding amount of the notes of the series may declare
the principal amount of all the notes of the series to be due and payable
immediately. The declaration may, in some circumstances, be rescinded and
annulled by the holders of a majority in aggregate outstanding amount of the
related notes.

         If following an event of default with respect to any series of notes,
the notes of the series have been declared to be due and payable, the trustee
may, in its discretion, notwithstanding the acceleration, elect to maintain
possession of the collateral securing the notes of the series and to continue to
apply payments on the collateral as if there had been no declaration of
acceleration if the collateral continues to provide sufficient funds for the
payment of principal of and interest on the notes of the series as they would
have become due if there had not been a declaration. In addition, the trustee
may not sell or otherwise liquidate the collateral securing the notes of a
series following an event of default, unless (1) the holders of 100% of the then
aggregate outstanding amount of the notes of the series consent to the sale, (2)
the proceeds of the sale or liquidation are sufficient to pay in full the
principal of and accrued interest, due and unpaid, on the outstanding notes of
the series at the date of the sale or (3) the trustee determines that the
collateral would not be sufficient on an ongoing basis to make all payments on
the notes as the payments would have become due if the notes had not been
declared due and payable, and the trustee obtains the consent of the holders of
66 2/3% of the then aggregate outstanding amount of the notes of the series.

         In the event that the trustee liquidates the collateral in connection
with an event of default, the indenture provides that the trustee will have a
prior lien on the proceeds of the liquidation for unpaid fees and expenses. As a
result, upon the occurrence of the event of default, the amount available for
payments to the noteholders would be less than would otherwise be the case.
However, the trustee may not institute a proceeding for the enforcement of its
lien except in connection with a proceeding for the enforcement of the lien of
the indenture for the benefit of the noteholders after the occurrence of the
event of default.

                                     - 74 -


         In the event the principal of the notes of a series is declared due and
payable, as described above, the holders of the notes issued at a discount from
par may be entitled to receive no more than an amount equal to the unpaid
principal amount thereof less the amount of the discount that is unamortized.

         No noteholder or holder of an Equity Certificate generally will have
any right under an owner trust agreement or indenture to institute any
proceeding with respect to the Agreement unless (1) that holder previously has
given to the trustee written notice of default and the continuance thereof, (2)
the holders of notes or Equity Certificates of any class evidencing not less
than 25% of the aggregate Percentage Interests constituting that class (a) have
made written request upon the trustee to institute the proceeding in its own
name as trustee and (b) have offered to the trustee reasonable security or
indemnity against the costs, expenses and liabilities that may be incurred in or
because of the proceeding, (3) the trustee has neglected or refused to institute
the proceeding for 60 days after receipt of the request and indemnity and (4) no
direction inconsistent with the written request has been given to the trustee
during the 60- day period by the holders of a majority of the Note Balances of
that class.

AMENDMENT

         Each pooling and servicing agreement may be amended by the parties
thereto, without the consent of any of the holders of certificates covered by
the pooling and servicing agreement,

         o        to cure any ambiguity,

         o        to correct, modify or supplement any provision therein which
                  may be inconsistent with any other provision therein or to
                  correct any error,

         o        if a REMIC election has been made with respect to the related
                  trust fund, to modify, eliminate or add to any of its
                  provisions (A) to the extent as shall be necessary to maintain
                  the qualification of the trust fund as a REMIC or to avoid or
                  minimize the risk of imposition of any tax on the related
                  trust fund, provided that the trustee has received an opinion
                  of counsel to the effect that (1) the action is necessary or
                  desirable to maintain the qualification or to avoid or
                  minimize the risk, and (2) the action will not adversely
                  affect in any material respect the interests of any holder of
                  certificates covered by the pooling and servicing agreement,
                  or (B) to restrict the transfer of the REMIC Residual
                  Certificates, provided that the depositor has determined that
                  the then-current ratings of the classes of the certificates
                  that have been rated will not be adversely affected, as
                  evidenced by a letter from each applicable Rating Agency, and
                  that the amendment will not give rise to any tax with respect
                  to the transfer of the REMIC Residual Certificates to a
                  non-permitted transferee,

         o        to make any other provisions with respect to matters or
                  questions arising under the pooling and servicing agreement
                  which are not materially inconsistent with the provisions
                  thereof, provided that the action will not adversely affect in
                  any material respect the interests of any certificateholder,
                  or

                                     - 75 -


         o        to comply with any changes in the Code.

The pooling and servicing agreement may also be amended by the parties thereto
with the consent of the holders of certificates of each class affected thereby
evidencing, in each case, at least 66% of the aggregate Percentage Interests
constituting the class for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the pooling and servicing
agreement or of modifying in any manner the rights of the holders of
certificates covered by the pooling and servicing agreement, except that the
amendment may not (1) reduce in any manner the amount of, or delay the timing
of, payments received on mortgage loans which are required to be distributed on
a certificate of any class without the consent of the holder of the certificate
or (2) reduce the aforesaid percentage of certificates of any class the holders
of which are required to consent to the amendment without the consent of the
holders of all certificates of the class covered by the pooling and servicing
agreement then outstanding.

         Notwithstanding the foregoing, if a REMIC election has been made with
respect to the related trust fund, the trustee will not be entitled to consent
to any amendment to a pooling and servicing agreement without having first
received an opinion of counsel to the effect that the amendment or the exercise
of any power granted to the master servicer, the depositor, the trustee or any
other specified person in accordance with the amendment will not result in the
imposition of a tax on the related trust fund or cause the trust fund to fail to
qualify as a REMIC.

         With respect to each series of notes, each related servicing agreement
or indenture may be amended by the parties thereto without the consent of any of
the holders of the notes covered by the Agreement, to cure any ambiguity, to
correct, modify or supplement any provision therein, or to make any other
provisions with respect to matters or questions arising under the Agreement
which are not inconsistent with the provisions thereof, provided that the action
will not adversely affect in any material respect the interests of any holder of
notes covered by the Agreement. Each Agreement may also be amended by the
parties thereto with the consent of the holders of notes evidencing not less
than 66% of the voting rights, for any purpose; provided, however, that the
amendment may not:

         (1)      reduce in any manner the amount of or delay the timing of,
                  payments received on trust fund assets which are required to
                  be distributed on any certificate without the consent of the
                  holder of the certificate,

         (2)      adversely affect in any material respect the interests of the
                  holders of any class of notes in a manner other than as
                  described in (1), without the consent of the holders of notes
                  of the class evidencing not less than 66% of the aggregate
                  voting rights of the class or

         (3)      reduce the aforesaid percentage of voting rights required for
                  the consent to the amendment without the consent of the
                  holders of all notes covered by the Agreement then
                  outstanding.

The voting rights evidenced by any security will be the portion of the voting
rights of all of the securities in the related series allocated in the manner
described in the related prospectus supplement.

                                     - 76 -


TERMINATION; RETIREMENT OF SECURITIES

         The obligations created by the related Agreements for each series of
securities (other than the limited payment and notice obligations of the trustee
and the depositor, respectively) will terminate upon the payment to
securityholders of that series of all amounts held in the Certificate Account or
by the master servicer and required to be paid to them pursuant to the
Agreements following the earlier of (1) the final payment or other liquidation
or disposition (or any advance with respect thereto) of the last mortgage loan,
REO property and/or mortgage security subject thereto and (2) the purchase by
the master servicer or the depositor or (a) if specified in the related
prospectus supplement with respect to each series of certificates, by the holder
of the REMIC Residual Certificates (see "Federal Income Tax Consequences" below)
or (b) if specified in the prospectus supplement with respect to each series of
notes, by the holder of the Equity Certificates, from the trust fund for the
series of all remaining mortgage loans, REO properties and/or mortgage
securities. In addition to the foregoing, the master servicer or the depositor
will have the option to purchase, in whole but not in part, the securities
specified in the related prospectus supplement in the manner set forth in the
related prospectus supplement. With respect to any series of certificates, the
purchase shall not be made unless either: (1) the aggregate principal balance of
the certificates as of the date is equal to or less than the percentage
specified in the related prospectus supplement (which shall not be greater than
10%) of the aggregate principal balance of the certificates as of the Closing
Date or (2) the aggregate principal balance of the mortgage loans as of the date
is equal to or less than the percentage specified in the related prospectus
supplement (which shall not be greater than 10%) of the aggregate principal
balance of the mortgage loans as of the cut-off date. With respect to any series
of notes, the purchase shall not be made unless the aggregate principal balance
of the notes as of the date is equal to or less than the percentage specified in
the related prospectus supplement (which shall not be greater than 25%) of the
aggregate principal balance of the notes as of the Closing Date or a period
specified in the related prospectus supplement (which shall not be shorter than
seven years) has elapsed since the initial distribution date. Upon the purchase
of the securities or at any time thereafter, at the option of the master
servicer or the depositor, the assets of the trust fund may be sold, thereby
effecting a retirement of the securities and the termination of the trust fund,
or the securities so purchased may be held or resold by the master servicer or
the depositor. In no event, however, will the trust created by the pooling and
servicing agreement continue beyond the expiration of 21 years from the death of
the survivor of the persons named in the pooling and servicing agreement.
Written notice of termination of the pooling and servicing agreement will be
given to each securityholder, and the final distribution will be made only upon
surrender and cancellation of the securities at an office or agency appointed by
the trustee which will be specified in the notice of termination. If the
securityholders are permitted to terminate the trust under the applicable
pooling and servicing agreement, a penalty may be imposed upon the
securityholders based upon the fee that would be foregone by the master servicer
because of the termination.

         The purchase of mortgage loans and property acquired in respect of
mortgage loans evidenced by a series of securities shall be made at the option
of the master servicer, the depositor or, if applicable, the holder of the REMIC
Residual Certificates or Equity Certificates at the price specified in the
related prospectus supplement. The exercise of the right will effect early
retirement of the securities of that series, but the right of the master
servicer, the depositor or, if applicable, the holder to so purchase is subject
to the aggregate principal balance of the mortgage loans and/or mortgage
securities in the trust fund for that series as of the distribution date on
which the purchase


                                     - 77 -


proceeds are to be distributed to securityholders being less than the percentage
specified in the related prospectus supplement of the aggregate principal
balance of the mortgage loans and/or mortgage securities at the cut-off date for
that series. The prospectus supplement for each series of securities will set
forth the amounts that the holders of the securities will be entitled to receive
upon the early retirement. The early termination may adversely affect the yield
to holders of the securities. With respect to any series of certificates, an
optional purchase of the mortgage loans in the related trust fund may not result
in the related certificates receiving an amount equal to the principal balance
thereof plus accrued and unpaid interest and any undistributed shortfall on the
related certificates. If a REMIC election has been made, the termination of the
related trust fund will be effected in a manner consistent with applicable
federal income tax regulations and its status as a REMIC.

         Following any optional termination, there will be no continuing direct
or indirect liability of the trust fund or any securityholder as sellers of the
assets of the trust fund.

THE TRUSTEE

         The trustee under each pooling and servicing agreement and indenture
will be named in the related prospectus supplement. The commercial bank,
national banking association, banking corporation or trust company that serves
as trustee may have typical banking relationships with the depositor and its
affiliates. The trustee shall at all times be a corporation or an association
organized and doing business under the laws of any state or the United States of
America, authorized under the laws to exercise corporate trust powers, having a
combined capital and surplus of at least $15,000,000 and subject to supervision
or examination by federal or state authority.

DUTIES OF THE TRUSTEE

         The trustee for each series of securities will make no representation
as to the validity or sufficiency of the related Agreements, the securities or
any underlying mortgage loan, mortgage security or related document and will not
be accountable for the use or application by or on behalf of any master servicer
or special servicer of any funds paid to the master servicer or special servicer
in respect of the securities or the underlying mortgage loans or mortgage
securities, or any funds deposited into or withdrawn from the Certificate
Account for the series or any other account by or on behalf of the master
servicer or special servicer. If no event of default has occurred and is
continuing, the trustee for each series of securities will be required to
perform only those duties specifically required under the related pooling and
servicing agreement or indenture. However, upon receipt of any of the various
certificates, reports or other instruments required to be furnished to it
pursuant to the related Agreement, a trustee will be required to examine the
documents and to determine whether they conform to the requirements of the
agreement.

         If an event of default shall occur, then, and in each and every such
case, so long as such event of default shall not have been remedied, the Trustee
or the Certificateholders entitled to at least 51% of the voting rights, by
notice in writing to the Master Servicer (and to the Trustee if given by such
Holders of Certificates), with a copy to the Rating Agencies, may terminate all
of the rights and obligations (but not the liabilities) of the Master Servicer
and in and to the trust fund, other than its rights as a Certificateholder;
PROVIDED, HOWEVER, that the successor to the



                                     - 78 -


Master Servicer shall have accepted the duties of Master Servicer effective upon
the resignation or termination of the Master Servicer. On or after the delivery
to the Master Servicer of such notice, all authority and power of the Master
Servicer, whether with respect to the securities (other than as a Holder
thereof) or the mortgage loans or otherwise, shall pass to and be vested in the
Trustee, and, without limitation, the Trustee is authorized and empowered to
execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or
assignment of the mortgage loans and related documents, or otherwise at the
expense of the Master Servicer. The Master Servicer agrees to cooperate with
(and pay any related costs and expenses of) the Trustee in effecting the
termination of the Master Servicer's responsibilities and right, including,
without limitation, the transfer to the Trustee or another successor master
servicer for administration by it of (i) the property and amounts which are then
or should be part of the trust fund or which thereafter become part of the trust
fund; (ii) originals or copies of all documents of the Master Servicer
reasonably requested by the Trustee to enable a successor to assume the Master
Servicer's duties; (iii) the rights and obligations of the Master Servicer under
the Subservicing Agreements with respect to the mortgage loans; and (iv) all
cash amounts which shall at the time be deposited by the Master Servicer or
should have been deposited to the Distribution Account or thereafter be received
with respect to the mortgage loans.

         Within 90 days of the time the Master Servicer receives a notice of
termination, the Trustee another successor appointed as set forth herein shall
be the successor in all respects to the Master Servicer in its capacity as
Master Servicer under the related Agreement and the transactions set forth or
provided for therein and shall be subject thereafter to all the
responsibilities, duties and liabilities relating thereto placed on the Master
Servicer including the obligation to make Advances which have been or will be
required to be made by the terms and provisions thereof; and provided further,
that any failure to perform such duties or responsibilities caused by the Master
Servicer's failure to provide information required by the related Agreement
shall not be considered a default by the successor master servicer. As
compensation therefor, the Trustee or another successor master servicer shall be
entitled to all funds relating to the mortgage loans which the Master Servicer
would have been entitled to charge to the Distribution Account if the Master
Servicer had continued to act. If the Trustee has become the successor to the
Master Servicer, then notwithstanding the above, if the Trustee shall be
unwilling to so act, or shall be unable to so act, the Trustee may appoint, or
petition a court of competent jurisdiction to appoint, any established housing
and home finance institution, which is also a Fannie Mae- or Freddie
Mac-approved mortgage servicing institution, having a net worth of not less than
$10,000,000 as the successor to the Master Servicer in the assumption of all or
any part of the responsibilities, duties or liabilities of the Master Servicer.
Pending appointment of a successor to the Master Servicer, the Trustee shall act
in such capacity as herein above provided. In connection with such appointment
and assumption, the Trustee may make such arrangements for the compensation of
such successor out of payments on mortgage loans as it and such successor shall
agree; provided, however, that no such compensation shall be in excess of that
permitted the Master Servicer. The Depositor, the Trustee and such successor
shall take such action, consistent with the related Agreement, as shall be
necessary to effectuate any such succession. In no event shall the successor
master servicer be liable for the acts or omissions of the predecessor Master
Servicer.

                                     - 79 -


         Upon any such termination or appointment of a successor to the Master
Servicer, the Trustee shall give prompt notice thereof to Certificateholders and
to the Rating Agencies. Within 60 days after the occurrence of any event of
default, the Trustee shall transmit by mail to all Certificateholders notice of
each such event of default hereunder known to the Trustee, unless such event of
default shall have been cured or waived.

         Upon written request of three or more Certificateholders of record, for
purposes of communicating with other Certificateholders with respect to their
rights under the pooling and servicing agreement, the Trustee will afford such
Certificateholders access during business hours to the most recent list of
Certificateholders held by the Trustee.

SOME MATTERS REGARDING THE TRUSTEE

         As and to the extent described in the related prospectus supplement,
the fees and normal disbursements of any trustee may be the expense of the
related master servicer or other specified person or may be required to be borne
by the related trust fund.

         The trustee for each series of securities generally will be entitled to
indemnification, from amounts held in the Certificate Account for the series,
for any loss, liability or expense incurred by the trustee in connection with
the trustee's acceptance or administration of its trusts under the related
pooling and servicing agreement or indenture unless the loss, liability, cost or
expense was incurred by reason of willful misfeasance, bad faith or gross
negligence on the part of the trustee in the performance of its obligations and
duties, or by reason of its reckless disregard of its obligations or duties.

RESIGNATION AND REMOVAL OF THE TRUSTEE

         The trustee may resign at any time, in which event the depositor will
be obligated to appoint a successor trustee. The depositor may also remove the
trustee if the trustee ceases to be eligible to continue under the pooling and
servicing agreement or if the trustee becomes insolvent. Upon becoming aware of
the circumstances, the depositor will be obligated to appoint a successor
trustee. The trustee may also be removed at anytime by the holders of securities
evidencing not less than 51% of the aggregate undivided interests (or, if
applicable, voting rights) in the related trust fund. Any resignation or removal
of the trustee and appointment of a successor trustee will not become effective
until acceptance of the appointment by the successor trustee.

                              YIELD CONSIDERATIONS

         The yield to maturity of an offered certificate will depend on the
price paid by the holder for the certificate, the security interest rate on a
certificate entitled to payments of interest (which security interest rate may
vary if so specified in the related prospectus supplement) and the rate and
timing of principal payments (including prepayments, defaults, liquidations and
repurchases) on the mortgage loans and the allocation thereof to reduce the
principal balance of the certificate (or notional amount thereof if applicable)
and other factors.


                                     - 80 -


         A class of securities may be entitled to payments of interest at a
fixed security interest rate, a variable security interest rate or adjustable
security interest rate, or any combination of the security interest rates, each
as specified in the related prospectus supplement. A variable security interest
rate may be calculated based on the weighted average of the Net Mortgage Rates
of the related mortgage loans for the month preceding the distribution date if
so specified in the related prospectus supplement. As will be described in the
related prospectus supplement, the aggregate payments of interest on a class of
securities, and their yield to maturity, will be affected by the rate of payment
of principal on the securities (or the rate of reduction in the notional balance
of securities entitled only to payments of interest) and, in the case of
securities evidencing interests in ARM Loans, by changes in the Net Mortgage
Rates on the ARM Loans. See "Maturity and Prepayment Considerations" below. The
yield on the securities will also be affected by liquidations of mortgage loans
following mortgagor defaults and by purchases of mortgage loans in the event of
breaches of representations made in respect of the mortgage loans by the
depositor, the master servicer and others, or conversions of ARM Loans to a
fixed interest rate. See "The Mortgage Pools--Representations by Sellers" and
"Descriptions of the Securities--Assignment of Trust Fund Assets" above. Holders
of Strip Securities or a class of securities having a security interest rate
that varies based on the weighted average mortgage rate of the underlying
mortgage loans may be affected by disproportionate prepayments and repurchases
of mortgage loans having higher Net Mortgage Rates or rates applicable to the
Strip Securities, as applicable.

         With respect to any series of securities, a period of time will elapse
between the date upon which payments on the related mortgage loans are due and
the distribution date on which the payments are passed through to
Certificateholders. That delay will effectively reduce the yield that would
otherwise be produced if payments on the mortgage loans were distributed to
Certificateholders on or near the date they were due.

         In general, if a class of securities is purchased at initial issuance
at a premium and payments of principal on the related mortgage loans occur at a
rate faster than anticipated at the time of purchase, the purchaser's actual
yield to maturity will be lower than that assumed at the time of purchase.
Similarly, if a class of securities is purchased at initial issuance at a
discount and payments of principal on the related mortgage loans occur at a rate
slower than that assumed at the time of purchase, the purchaser's actual yield
to maturity will be lower than that originally anticipated. The effect of
principal prepayments, liquidations and purchases on yield will be particularly
significant in the case of a series of securities having a class entitled to
payments of interest only or to payments of interest that are disproportionately
high relative to the principal payments to which the class is entitled. This
class will likely be sold at a substantial premium to its principal balance and
any faster than anticipated rate of prepayments will adversely affect the yield
to holders thereof. Extremely rapid prepayments may result in the failure of the
holders to recoup their original investment. In addition, the yield to maturity
on other types of classes of securities, including Accrual Securities and
securities with a security interest rate which fluctuates inversely with or at a
multiple of an index, may be relatively more sensitive to the rate of prepayment
on the related mortgage loans than other classes of securities.

         The timing of changes in the rate of principal payments on or
repurchases of the mortgage loans may significantly affect an investor's actual
yield to maturity, even if the average rate of principal payments experienced
over time is consistent with an investor's expectation. In



                                     - 81 -


general, the earlier a prepayment of principal on the underlying mortgage loans
or a repurchase thereof, the greater will be the effect on an investor's yield
to maturity. As a result, the effect on an investor's yield of principal
payments and repurchases occurring at a rate higher (or lower) than the rate
anticipated by the investor during the period immediately following the issuance
of a series of securities would not be fully offset by a subsequent like
reduction (or increase) in the rate of principal payments.

         When a principal prepayment in full is made on a mortgage loan, the
borrower is generally charged interest only for the period from the due date of
the preceding scheduled payment up to the date of the prepayment, instead of for
the full accrual period, that is, the period from the due date of the preceding
scheduled payment up to the due date for the next scheduled payment. In
addition, a partial principal prepayment may likewise be applied as of a date
prior to the next scheduled due date (and, accordingly, be accompanied by
accrued interest for less than the full accrual period). However, interest
accrued and distributable on any series of securities on any distribution date
will generally correspond to interest accrued on the principal balance of
mortgage loans for their respective full accrual periods. Consequently, if a
prepayment on any mortgage loan is distributable to Certificateholders on a
particular distribution date, but the prepayment is not accompanied by accrued
interest for the full accrual period, the interest charged to the borrower (net
of servicing and administrative fees and any retained interest of the depositor)
may be less than the corresponding amount of interest accrued and otherwise
payable on the related mortgage loan, and a Prepayment Interest Shortfall will
result. If and to the extent that the shortfall is allocated to a class of
offered securities, its yield will be adversely affected. The prospectus
supplement for a series of securities will describe the manner in which the
shortfalls will be allocated among the classes of the securities. If so
specified in the related prospectus supplement, the master servicer will be
required to apply some or all of its servicing compensation for the
corresponding period to offset the amount of the shortfalls. The related
prospectus supplement will also describe any other amounts available to off set
the shortfalls. See "Servicing of Mortgage Loans -- Servicing and Other
Compensation and Payment of Expenses; Retained Interest".

         The trust fund with respect to any series may include convertible ARM
Loans. As is the case with conventional, fixed-rate mortgage loans originated in
a high interest rate environment which may be subject to a greater rate of
principal prepayments when interest rates decrease, convertible ARM Loans may be
subject to a greater rate of principal prepayments (or purchases by the related
subservicer or the master servicer) due to their refinancing or conversion to
fixed interest rate loans in a low interest rate environment. For example, if
prevailing interest rates fall significantly, convertible ARM Loans could be
subject to higher prepayment and conversion rates than if prevailing interest
rates remain constant because the availability of fixed-rate or other
adjustable-rate mortgage loans at competitive interest rates may encourage
mortgagors to refinance their adjustable-rate mortgages to "lock in" a lower
fixed interest rate or to take advantage of the availability of other
adjustable-rate mortgage loans, or, in the case of convertible adjustable-rate
mortgage loans, to exercise their option to convert the adjustable interest
rates to fixed interest rates. The conversion feature may also be exercised in
arising interest rate environment as mortgagors attempt to limit their risk of
higher rates. A rising interest rate environment may also result in an increase
in the rate of defaults on the mortgage loans. If the related subservicer or the
master servicer purchases convertible ARM Loans, a mortgagor's exercise of the
conversion option will result in a distribution of the principal portion



                                     - 82 -


thereof to the Certificateholders, as described in this prospectus.
Alternatively, to the extent subservicers or the master servicer fail to
purchase converting ARM Loans, the mortgage pool will include fixed-rate
mortgage loans.

         The rate of defaults on the mortgage loans will also affect the rate
and timing of principal payments on the mortgage loans and thus the yield on the
securities. In general, defaults on single family loans are expected to occur
with greater frequency in their early years. The rate of default on single
family loans which are refinance or limited documentation mortgage loans, and on
mortgage loans, with high loan-to-value ratios, may be higher than for other
types of mortgage loans. Furthermore, the rate and timing of prepayments,
defaults and liquidations on the mortgage loans will be affected by the general
economic condition of the region of the country in which the related mortgaged
properties are located. The risk of delinquencies and loss is greater and
prepayments are less likely in regions where a weak or deteriorating economy
exists, as may be evidenced by, among other factors, increasing unemployment or
falling property values.

         With respect to some mortgage loans in a mortgage pool, the mortgage
rate at origination may be below the rate that would result if the index and
margin relating thereto were applied at origination. Under the applicable
underwriting standards, the mortgagor under each mortgage loan generally will be
qualified, or the mortgage loan otherwise approved, on the basis of the mortgage
rate in effect at origination. The repayment of the mortgage loan may thus be
dependent on the ability of the mortgagor to make larger level monthly payments
following the adjustment of the mortgage rate. In addition, the periodic
increase in the amount paid by the mortgagor of a buydown mortgage loan during
or at the end of the applicable Buydown Period may create a greater financial
burden for the mortgagor, who might not have otherwise qualified for a mortgage
under applicable underwriting guidelines, and may accordingly increase the risk
of default with respect to the related mortgage loan.

         The mortgage rates on ARM Loans subject to negative amortization
generally adjust monthly and their amortization schedules adjust less
frequently. During a period of rising interest rates as well as immediately
after origination(initial mortgage rates are generally lower than the sum of the
Indices applicable at origination and the related Note Margins), the amount of
interest accruing on the principal balance of the mortgage loans may exceed the
amount of their minimum scheduled monthly payment. As a result, a portion of the
accrued interest on negatively amortizing mortgage loans may become Deferred
Interest which will be added to the principal balance thereof and will bear
interest at the applicable mortgage rate. The addition of the Deferred Interest
to the principal balance of any related class or classes of securities will
lengthen the weighted average life thereof and may adversely affect yield to
holders thereof, depending upon the price at which the securities were
purchased. In addition, with respect to ARM Loans subject to negative
amortization, during a period of declining interest rates, it might be expected
that each minimum scheduled monthly payment on the mortgage loan would exceed
the amount of scheduled principal and accrued interest on the principal balance
thereof, and since the excess will be applied to reduce the principal balance of
the related class or classes of securities, the weighted average life of the
securities will be reduced and may adversely affect yield to holders thereof,
depending upon the price at which the securities were purchased.

                                     - 83 -


                     MATURITY AND PREPAYMENT CONSIDERATIONS

         As indicated above under "The Mortgage Pools," the original terms to
maturity of the mortgage loans in a given mortgage pool will vary depending upon
the type of mortgage loans included in the mortgage pool. The prospectus
supplement for a series of securities will contain information with respect to
the types and maturities of the mortgage loans in the related mortgage pool. All
of the mortgage loans may be prepaid without penalty in full or in part at
anytime. The prepayment experience with respect to the mortgage loans in a
mortgage pool will affect the life and yield of the related series of
securities.

         With respect to balloon loans, payment of the balloon payment (which,
based on the amortization schedule of the mortgage loans, is expected to be a
substantial amount) will generally depend on the mortgagor's ability to obtain
refinancing of the mortgage loans or to sell the mortgaged property prior to the
maturity of the balloon loan. The ability to obtain refinancing will depend on a
number of factors prevailing at the time refinancing or sale is required,
including real estate values, the mortgagor's financial situation, prevailing
mortgage loan interest rates, the mortgagor's equity in the related mortgaged
property, tax laws and prevailing general economic conditions. None of the
depositor, the master servicer, or any of their affiliates will be obligated to
refinance or repurchase any mortgage loan or to sell the mortgaged property.

         The extent of prepayments of principal of the mortgage loans may be
affected by a number of factors, including solicitations and the availability of
mortgage credit, the relative economic vitality of the area in which the
mortgaged properties are located and, in the case of multifamily, commercial and
mixed-use loans, the quality of management of the mortgage properties, the
servicing of the mortgage loans, possible changes in tax laws and other
opportunities for investment. In addition, the rate of principal payments on the
mortgage loans may be affected by the existence of lock-out periods and
requirements that principal prepayments be accompanied by prepayment premiums,
as well as due-on- sale and due-on-encumbrance provisions, and by the extent to
which the provisions may be practicably enforced. See "Servicing of Mortgage
Loans--Collection and Other Servicing Procedures" and "Legal Aspects of Mortgage
Loans--Enforceability of Some Provisions" for a description of provisions of the
pooling and servicing agreement and legal aspects of mortgage loans that may
affect the prepayment experience on the mortgage loans.

         The rate of prepayment on a pool of mortgage loans is also affected by
prevailing market interest rates for mortgage loans of a comparable type, term
and risk level. When the prevailing market interest rate is below a mortgage
coupon, a borrower may have an increased incentive to refinance its mortgage
loan. In addition, as prevailing market interest rates decline, even borrowers
with ARM Loans that have experienced a corresponding interest rate decline may
have an increased incentive to refinance for purposes of either (1) converting
to a fixed rate loan and thereby "locking in" the rate or (2) taking advantage
of the initial "teaser rate" (a mortgage interest rate below what it would
otherwise be if the applicable index and gross margin were applied) on another
adjustable rate mortgage loan. Moreover, although the mortgage rates on ARM
Loans will be subject to periodic adjustments, the adjustments generally will
not increase or decrease the mortgage rates by more than a fixed percentage
amount on each adjustment date, will not increase the mortgage rates over a
fixed percentage amount during the life of any ARM



                                     - 84 -


Loan and will be based on an index (which may not rise and fall consistently
with mortgage interest rates) plus the related Note Margin (which may be
different from margins being used at the time for newly originated adjustable
rate mortgage loans). As a result, the mortgage rates on the ARM Loans at any
time may not equal the prevailing rates for similar, newly originated adjustable
rate mortgage loans. In high interest rate environments, the prevailing rates on
fixed-rate mortgage loans may be sufficiently high in relation to the
then-current mortgage rates on newly originated ARM Loans that the rate of
prepayment may increase as a result of refinancings. There can be no assurance
as to the rate of prepayments on the mortgage loans during any period or over
the life of any series of securities.

         If the applicable pooling and servicing agreement for a series of
securities provides for a pre-funding account or other means of funding the
transfer of additional mortgage loans to the related trust fund, as described
under "Description of the Securities--Pre-Funding Account" in this prospectus,
and the trust fund is unable to acquire the additional mortgage loans within any
applicable time limit, the amounts set aside for the purpose may be applied as
principal payments on one or more classes of securities of the series. See
"Yield Considerations."

         There can be no assurance as to the rate of prepayment of the mortgage
loans. The depositor is not aware of any publicly available statistics relating
to the principal prepayment experience of diverse portfolios of mortgage loans
such as the mortgage loans over an extended period of time. All statistics known
to the depositor that have been compiled with respect to prepayment experience
on mortgage loans indicate that while some mortgage loans may remain outstanding
until their stated maturities, a substantial number will be paid prior to their
respective stated maturities. No representation is made as to the particular
factors that will affect the prepayment of the mortgage loans or as to the
relative importance of these factors.

         As described in this prospectus and in the prospectus supplement,
teamster servicer, the depositor or a person specified in the related prospectus
supplement (other than holder of any class of offered certificates, other than
the REMIC Residual Certificates, if offered) may have the option to purchase the
assets in a trust fund and effect early retirement of the related series of
securities. See "The Agreements--Termination; Retirement of Securities."

                         LEGAL ASPECTS OF MORTGAGE LOANS

         The following discussion summarizes legal aspects of mortgage loans
that is general in nature. The summaries do not purport to be complete. They do
not reflect the laws of any particular state nor the laws of all states in which
the mortgaged properties may be situated. This is because these legal aspects
are governed in part by the law of the state that applies to a particular
mortgaged property and the laws of the states may vary substantially. You should
refer to the applicable federal and state laws governing the mortgage loans.

MORTGAGES

         Each single family, multifamily, commercial and mixed-use loan and, if
applicable, the Contracts (in each case other than cooperative mortgage loans),
will be evidenced by a note or bond and secured by an instrument granting a
security interest in real property, which may be a mortgage, deed of trust or a
deed to secure debt, depending upon the prevailing practice and law



                                     - 85 -


in the state in which the related mortgaged property is located, and may have
first, second or third priority. Mortgages and deeds to secure debt are referred
to as "mortgages." Contracts evidence both the obligation of the obligor to
repay the loan evidenced thereby and grant a security interest in the related
Manufactured Homes to secure repayment of the loan. However, as Manufactured
Homes have become larger and often have been attached to their sites without any
apparent intention by the borrowers to move them, courts in many states have
held that Manufactured Homes may become subject to real estate title and
recording laws. See "--Contracts" below. In some states, a mortgage or deed of
trust creates a lien upon the real property encumbered by the mortgage or deed
of trust. However, in other states, the mortgage or deed of trust conveys legal
title to the property respectively, to the mortgagee or to a trustee for the
benefit of the mortgagee subject to a condition subsequent (i.e., the payment of
the indebtedness secured thereby). The lien created by the mortgage or deed of
trust is not prior to the lien for real estate taxes and assessments and other
charges imposed under governmental police powers. Priority between mortgages
depends on their terms or on the terms of separate subordination or
inter-creditor agreements, the knowledge of the parties in some cases and
generally on the order of recordation of the mortgage in the appropriate
recording office. There are two parties to a mortgage, the mortgagor, who is the
borrower and homeowner, and the mortgagee, who is the lender. Under the mortgage
instrument, the mortgagor delivers to the mortgagee a note or bond and the
mortgage. In the case of a land trust, there are three parties because title to
the property is held by a land trustee under a land trust agreement of which the
borrower is the beneficiary; at origination of a mortgage loan, the borrower
executes a separate undertaking to make payments on the mortgage note. Although
a deed of trust is similar to a mortgage, a deed of trust has three parties: the
trustor who is the borrower-homeowner; the beneficiary who is the lender; and a
third-party grantee called the trustee. Under a deed of trust, the borrower
grants the property, irrevocably until the debt is paid, in trust, generally
with a power of sale, to the trustee to secure payment of the obligation. The
trustee's authority under a deed of trust, the grantee's authority under a deed
to secure debt and the mortgagee's authority under a mortgage are governed by
the law of the state in which the real property is located, the express
provisions of the deed of trustor mortgage, and, in deed of trust transactions,
the directions of the beneficiary.

COOPERATIVE MORTGAGE LOANS

         If specified in the prospectus supplement relating to a series of
certificates, the mortgage loans and Contracts may include cooperative mortgage
loans. Each mortgage note evidencing a cooperative mortgage loan will be secured
by a security interest in shares issued by the related Cooperative, and in the
related proprietary lease or occupancy agreement granting exclusive rights to
occupy a specific dwelling unit in the Cooperative's building. The security
agreement will create a lien upon the shares of the Cooperative, the priority of
which will depend on, among other things, the terms of the particular security
agreement as well as the order of recordation and/or filing of the agreement (or
financing statements related thereto) in the appropriate recording office.

         All Cooperative buildings relating to the cooperative mortgage loans
are located primarily in the State of New York. Generally, each Cooperative owns
in fee or has a long-term leasehold interest in all the real property and owns
in fee or leases the building and all separate



                                     - 86 -


dwelling units therein. The Cooperative is directly responsible for property
management and, in most cases, payment of real estate taxes, other governmental
impositions and hazard and liability insurance. If there is an underlying
mortgage (or mortgages) on the Cooperative's building or underlying land, as is
generally the case, or an underlying lease of the land, as is the case in some
instances, the Cooperative, as mortgagor or lessor, as the case may be, is also
responsible for fulfilling the mortgage or rental obligations. An underlying
mortgage loan is ordinarily obtained by the Cooperative in connection with
either the construction or purchase of the Cooperative's building or the
obtaining of capital by the Cooperative. The interest of the occupant under
proprietary leases or occupancy agreements as to which that Cooperative is the
landlord is generally subordinate to the interest of the holder of an underlying
mortgage and to the interest of the holder of a land lease. If the Cooperative
is unable to meet the payment obligations (1) arising under an underlying
mortgage, the mortgagee holding an underlying mortgage could foreclose on that
mortgage and terminate all subordinate proprietary leases and occupancy
agreements or (2) arising under its land lease, the holder of the landlord's
interest under the land lease could terminate it and all subordinate proprietary
leases and occupancy agreements. In addition, an underlying mortgage on a
Cooperative may provide financing in the form of a mortgage that does not fully
amortize, with a significant portion of principal being due in one final payment
at maturity. The inability of the Cooperative to refinance a mortgage and its
consequent inability to make the final payment could lead to foreclosure by the
mortgagee. Similarly, a land lease has an expiration date and the inability of
the Cooperative to extend its term or, in the alternative, to purchase the land,
could lead to termination of the Cooperative's interest in the property and
termination of all proprietary leases and occupancy agreements. In either event,
a foreclosure by the holder of an underlying mortgage or the termination of the
underlying lease could eliminate or significantly diminish the value of any
collateral held by the mortgagee who financed the purchase by an individual
tenant-stockholder of shares of the Cooperative or, in the case of the mortgage
loans, the collateral securing the cooperative mortgage loans.

         Each Cooperative is owned by shareholders (referred to as
tenant-stockholders) who, through ownership of stock or shares in the
Cooperative, receive proprietary leases or occupancy agreements which confer
exclusive rights to occupy specific dwellings. Generally, a tenant-stockholder
of a Cooperative must make a monthly payment to the Cooperative pursuant to the
proprietary lease, which payment represents the tenant-stockholder's
proportional share of the Cooperative's payments for its underlying mortgage,
real property taxes, maintenance expenses and other capital or ordinary
expenses. An ownership interest in a Cooperative and accompanying occupancy
rights may be financed through a cooperative mortgage loan evidenced by a
mortgage note and secured by an assignment of and a security interest in the
occupancy agreement or proprietary lease and a security interest in the related
shares of the related Cooperative. The mortgagee generally takes possession of
the share certificate and a counterpart of the proprietary lease or occupancy
agreement and a financing statement covering the proprietary lease or occupancy
agreement and the Cooperative shares is filed in the appropriate state and local
offices to perfect the mortgagee's interest in its collateral. Subject to the
limitations discussed below, upon default of the tenant-stockholder, the lender
may sue for judgment on the mortgage note, dispose of the collateral at a public
or private sale or otherwise proceed against the collateral or
tenant-stockholder as an individual as provided in the security agreement
covering the assignment of the proprietary lease or occupancy agreement and the
pledge of Cooperative shares. See "--Foreclosure on Shares of Cooperatives"
below.

                                     - 87 -


TAX ASPECTS OF COOPERATIVE OWNERSHIP

         In general, a "tenant-stockholder" (as defined in Section 216(b)(2) of
the Code) of a corporation that qualifies as a "cooperative housing corporation"
within the meaning of Section 216(b)(1) of the Code is allowed a deduction for
amounts paid or accrued within his taxable year to the corporation representing
his proportionate share of interest expenses and real estate taxes allowable as
a deduction under Section 216(a) of the Code to the corporation under Sections
163 and 164 of the Code. In order for a corporation to qualify under Section
216(b)(1) of the Code for its taxable year in which the items are allowable as a
deduction to the corporation, the section requires, among other things, that at
least 80% of the gross income of the corporation be derived from its
tenant-stockholders. By virtue of this requirement, the status of a corporation
for purposes of Section 216(b)(1) of the Code must be determined on a
year-to-year basis. Consequently, there can be no assurance that Cooperatives
relating to the cooperative mortgage loans will qualify under the section for
any particular year. In the event that the Cooperative fails to qualify for one
or more years, the value of the collateral securing any related cooperative
mortgage loans could be significantly impaired because no deduction would be
allowable to tenant-stockholders under Section 216(a) of the Code with respect
to those years. In view of the significance of the tax benefits accorded
tenant-stockholders of a corporation that qualifies under Section 216(b)(1) of
the Code, the likelihood that a failure would be permitted to continue over a
period of years appears remote.

LEASES AND RENTS

         Mortgages that encumber income-producing multifamily and commercial
properties often contain an assignment of rents and leases, pursuant to which
the borrower assigns to the lender the borrower's right, title and interest as
landlord under each lease and the income derived therefrom, while (unless rents
are to be paid directly to the lender) retaining a revocable license to collect
the rents for so long as there is no default. If the borrower defaults, the
license terminates and the lender is entitled to collect the rents. Local law
may require that the lender take possession of the property and/or obtain a
court-appointed receiver before becoming entitled to collect the rents.

CONTRACTS

         Under the laws of most states, manufactured housing constitutes
personal property and is subject to the motor vehicle registration laws of the
state or other jurisdiction in which the unit is located. In a few states, where
certificates of title are not required for manufactured homes, security
interests are perfected by the filing of a financing statement under Article 9
of the UCC which has been adopted by all states. Financing statements are
effective for five years and must be renewed prior to the end of each five year
period. The certificate of title laws adopted by the majority of states provide
that ownership of motor vehicles and manufactured housing shall be evidenced by
a certificate of title issued by the motor vehicles department (or a similar
entity) of the state. In the states that have enacted certificate of title laws,
a security interest in a unit of manufactured housing, so long as it is not
attached to land in so permanent a fashion as to become a fixture, is generally
perfected by the recording of the interest on the certificate of title



                                     - 88 -


to the unit in the appropriate motor vehicle registration office or by delivery
of the required documents and payment of a fee to the office, depending on state
law.

         The master servicer will be required under the related pooling and
servicing agreement or servicing agreement to effect the notation or delivery of
the required documents and fees, and to obtain possession of the certificate of
title, as appropriate under the laws of the state in which any Manufactured Home
is registered. In the event the master servicer fails, due to clerical errors or
otherwise, to effect the notation or delivery, or files the security interest
under the wrong law (for example, under a motor vehicle title statute rather
than under the UCC, in a few states), the trustee may not have a first priority
security interest in the Manufactured Home securing a Contract. As manufactured
homes have become larger and often have been attached to their sites without any
apparent intention by the borrowers to move them, courts in many states have
held that manufactured homes may become subject to real estate title and
recording laws. As a result, a security interest in a manufactured home could be
rendered subordinate to the interests of other parties claiming an interest in
the home under applicable state real estate law. In order to perfect a security
interest in a manufactured home under real estate laws, the holder of the
security interest must file either a "fixture filing" under the provisions of
the UCC or a real estate mortgage under the real estate laws of the state where
the home is located. These filings must be made in the real estate records
office of the county where the home is located. Generally, Contracts will
contain provisions prohibiting the obligor from permanently attaching the
Manufactured Home to its site. So long as the obligor does not violate this
agreement, a security interest in the Manufactured Home will be governed by the
certificate of title laws or the UCC, and the notation of the security interest
on the certificate of title or the filing of a UCC financing statement will be
effective to maintain the priority of the security interest in the Manufactured
Home. If, however, a Manufactured Home is permanently attached to its site,
other parties could obtain an interest in the Manufactured Home that is prior to
the security interest originally retained by the Seller and transferred to the
depositor.

         The depositor will assign or cause to be assigned a security interest
in the Manufactured Homes to the trustee, on behalf of the Certificateholders.
Neither the depositor, the master servicer nor the trustee will amend the
certificates of title to identify the trustee, on behalf of the
Certificateholders, as the new secured party and, accordingly, the depositor or
the Seller will continue to be named as the secured party on the certificates of
title relating to the Manufactured Homes. In most states, the assignment is an
effective conveyance of the security interest without amendment of any lien
noted on the related certificate of title and the new secured party succeeds to
the depositor's rights as the secured party. However, in some states there
exists a risk that, in the absence of an amendment to the certificate of title,
the assignment of the security interest might not be held effective against
creditors of the depositor or Seller.

         In the absence of fraud, forgery or permanent affixation of the
Manufactured Home to its site by the Manufactured Home owner, or administrative
error by state recording officials, the notation of the lien of the depositor on
the certificate of title or delivery of the required documents and fees will be
sufficient to protect the trustee against the rights of subsequent purchasers of
a Manufactured Home or subsequent lenders who take a security interest in the
Manufactured Home. If there are any Manufactured Homes as to which the depositor
has failed to perfect or cause to be perfected the security interest assigned to
the trust fund, the security interest would be subordinate to, among others,
subsequent purchasers for value of Manufactured



                                     - 89 -


Homes and holders of perfected security interests. There also exists a risk in
not identifying the trustee, on behalf of the Certificateholders, as the new
secured party on the certificate of title that, through fraud or negligence, the
security interest of the trustee could be released.

         In the event that the owner of a Manufactured Home moves it to a state
other than the state in which the Manufactured Home initially is registered,
under the laws of most states the perfected security interest in the
Manufactured Home would continue for four months after the relocation and
thereafter until the owner re-registers the Manufactured Home in the state. If
the owner were to relocate a Manufactured Home to another state and re-register
the Manufactured Home in the state, and if the depositor did not take steps to
re-perfect its security interest in the state, the security interest in the
Manufactured Home would cease to be perfected. A majority of states generally
require surrender of a certificate of title to re-register a Manufactured Home;
accordingly, the depositor must surrender possession if it holds the certificate
of title to the Manufactured Home or, in the case of Manufactured Homes
registered in states that provide for notation of lien, the depositor would
receive notice of surrender if the security interest in the Manufactured Home is
noted on the certificate of title. Accordingly, the depositor would have the
opportunity to re-perfect its security interest in the Manufactured Home in the
state of relocation. In states that do not require a certificate of title for
registration of a manufactured home, re-registration could defeat perfection.
Similarly, when an obligor under a manufactured housing conditional sales
contract sells a manufactured home, the obligee must surrender possession of the
certificate of title or it will receive notice as a result of its lien noted
thereon and accordingly will have an opportunity to require satisfaction of the
related manufactured housing conditional sales contract before release of the
lien. Under each related pooling and servicing agreement or servicing agreement,
the master servicer will be obligated to take these steps, at the master
servicer's expense, as are necessary to maintain perfection of security
interests in the Manufactured Homes.

         Under the laws of most states, liens for repairs performed on a
Manufactured Home take priority even over a perfected security interest. The
depositor will obtain the representation of the related Seller that it has no
knowledge of any of these liens with respect to any Manufactured Home securing a
Contract. However, these liens could arise at any time during the term of a
Contract. No notice will be given to the trustee or certificateholders in the
event this type of lien arises.

FORECLOSURE ON MORTGAGES AND SOME CONTRACTS

         Foreclosure of a deed of trust is generally accomplished by a
non-judicial trustee's sale under a specific provision in the deed of trust
which authorizes the trustee to sell the property upon any default by the
borrower under the terms of the note or deed of trust. In addition to any notice
requirements contained in a deed of trust, in some states, the trustee must
record a notice of default and send a copy to the borrower trustor and to any
person who has recorded a request for a copy of notice of default and notice of
sale. In addition, the trustee must provide notice in some states to any other
individual having an interest of record in the real property, including any
junior lienholders. If the deed of trust is not reinstated within a specified
period, a notice of sale must be posted in a public place and, in most states,
published for a specific period of time in one or more newspapers in a specified
manner prior to the date of trustee's sale. In addition,



                                     - 90 -


some state laws require that a copy of the notice of sale be posted on the
property and sent to all parties having an interest of record in the real
property.

         In some states, the borrower-trustor has the right to reinstate the
loan at any time following default until shortly before the trustee's sale. In
general, in these states, the borrower, or any other person having a junior
encumbrance on the real estate, may, during a reinstatement period, cure the
default by paying the entire amount in arrears plus the costs and expenses
incurred in enforcing the obligation.

         Foreclosure of a mortgage is generally accomplished by judicial action.
Generally, the action is initiated by the service of legal pleadings upon all
parties having an interest of record in the real property. Delays in completion
of the foreclosure may occasionally result from difficulties in locating
necessary parties. Judicial foreclosure proceedings are often not contested by
any of the applicable parties. If the mortgagee's right to foreclose is
contested, the legal proceedings necessary to resolve the issue can be
time-consuming.

         In the case of foreclosure under either a mortgage or a deed of trust,
the sale by the referee or other designated officer or by the trustee is a
public sale. However, because of the difficulty a potential buyer at the sale
would have in determining the exact status of title and because the physical
condition of the property may have deteriorated during the foreclosure
proceedings, it is uncommon for a third party to purchase the property at a
foreclosure sale. Rather, it is common for the lender to purchase the property
from the trustee or referee for a credit bid less than or equal to the unpaid
principal amount of note plus the accrued and unpaid interest and the expense of
foreclosure, in which case the mortgagor's debt will be extinguished unless the
lender purchases the property for a lesser amount in order to preserve its right
against a borrower to seek a deficiency judgment and the remedy is available
under state law and the related loan documents. In the same states, there is a
statutory minimum purchase price which the lender may offer for the property and
generally, state law controls the amount of foreclosure costs and expenses,
including attorneys' fees, which may be recovered by a lender. Thereafter,
subject to the right of the borrower in some states to remain in possession
during the redemption period, the lender will assume the burdens of ownership,
including obtaining hazard insurance, paying taxes and making the repairs at its
own expense as are necessary to render the property suitable for sale.
Generally, the lender will obtain the services of a real estate broker and pay
the broker's commission in connection with the sale of the property. Depending
upon market conditions, the ultimate proceeds of the sale of the property may
not equal the lender's investment in the property and, in some states, the
lender may be entitled to a deficiency judgment. Any loss may be reduced by the
receipt of any mortgage insurance proceeds or other forms of credit enhancement
for a series of certificates. See "Description of Credit Enhancement".

         A junior mortgagee may not foreclose on the property securing a junior
mortgage unless it forecloses subject to the senior mortgages. The junior
mortgagee must either pay the entire amount due on the senior mortgages prior to
or at the time of the foreclosure sale or undertake to pay on any senior
mortgages that the mortgagor is currently in a state of default under. Under
either course of action, the junior mortgagee may add the amounts paid to the
balance due on the junior loan, and may be subrogated to the rights of the
senior mortgagees. In addition, in the event that the foreclosure of a junior
mortgage triggers the enforcement of a "due-on-sale"



                                     - 91 -


clause, the junior mortgagee may be required to pay the full amount of the
senior mortgages to the senior mortgagees. Accordingly, with respect to those
single family loans which are junior mortgage loans, if the lender purchases the
property, the lender's title will be subject to all senior liens and claims and
governmental liens. The proceeds received by the referee or trustee from the
sale are applied first to the costs, fees and expenses of sale and then in
satisfaction of the indebtedness secured by the mortgage or deed of trust under
which the sale was conducted. Any remaining proceeds are generally payable to
the holders of junior mortgages or deeds of trust and other liens and claims in
order of their priority, whether or not the borrower is in default. Any
additional proceeds are generally payable to the mortgagor or trustor. The
payment of the proceeds to the holders of junior mortgages may occur in the
foreclosure action of the senior mortgagee or may require the institution of
separate legal proceeds.

         In foreclosure, courts have imposed general equitable principles. The
equitable principles are generally designed to relieve the borrower from the
legal effect of its defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have substituted their judgment for
the lender's judgment and have required that lenders reinstate loans or recast
payment schedules in order to accommodate borrowers who are suffering from
temporary financial disability. In other cases, courts have limited the right of
lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower's failure to adequately maintain the property or
the borrower's execution of a second mortgage or deed of trust affecting the
property. Finally, some courts have been faced with the issue of whether or not
federal or state constitutional provisions reflecting due process concerns for
adequate notice require that borrowers under deeds of trust or mortgages receive
notices in addition to the statutorily-prescribed minimums. For the most part,
these cases have upheld the notice provisions as being reasonable or have found
that the sale by a trustee under a deed of trust, or under a mortgage having a
power of sale, does not involve sufficient state action to afford constitutional
protection to the borrower.

FORECLOSURE ON SHARES OF COOPERATIVES

         The Cooperative shares owned by the tenant-stockholder, together with
the rights of the tenant- stockholder under the proprietary lease or occupancy
agreement, are pledged to the lender and are, in almost all cases, subject to
restrictions on transfer as set forth in the Cooperative's certificate of
incorporation and by-laws, as well as in the proprietary lease or occupancy
agreement. The Cooperative may cancel the proprietary lease or occupancy
agreement, even while pledged, for failure by the tenant- stockholder to pay its
obligations or charges owed by the tenant-stockholder, including mechanics'
liens against the Cooperative's building incurred by the tenant-stockholder.
Generally, obligations and charges arising under a proprietary lease or
occupancy agreement which are owed to the Cooperative are made liens upon the
shares to which the proprietary lease or occupancy agreement relates. In
addition, the Cooperative may generally terminate a proprietary lease or
occupancy agreement in the event the borrower breaches its covenants in the
proprietary lease or occupancy agreement. Typically, the lender and the
Cooperative enter into a recognition agreement which, together with any lender
protection provisions contained in the proprietary lease or occupancy agreement,
establishes the



                                     - 92 -


rights and obligations of both parties in the event of a default by the
tenant-stockholder on its obligations under the proprietary lease or occupancy
agreement. A default by the tenant-stockholder under the proprietary lease or
occupancy agreement will usually constitute a default under the security
agreement between the lender and the tenant-stockholder.

         The recognition agreement generally provides that, in the event that
the tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate the lease or
agreement until the lender has been provided with notice of and an opportunity
to cure the default. The recognition agreement typically provides that if the
proprietary lease or occupancy agreement is terminated, the Cooperative will
recognize the lender's lien against proceeds from a sale of the shares and the
proprietary lease or occupancy agreement allocated to the dwelling, subject,
however, to the Cooperative's right to sums due under the proprietary lease or
occupancy agreement or which have become liens on the shares relating to the
proprietary lease or occupancy agreement. The total amount owed to the
Cooperative by the tenant-stockholder, which the lender generally cannot
restrict and does not monitor, could reduce the amount realized upon a sale of
the collateral below the outstanding principal balance of the cooperative
mortgage loan and accrued and unpaid interest on the loan.

         Recognition agreements also generally provide that in the event the
lender succeeds to the tenant- shareholder's shares and proprietary lease or
occupancy agreement as the result of realizing upon its collateral for a
cooperative mortgage loan, the lender must obtain the approval or consent of the
board of directors of the Cooperative as required by the proprietary lease
before transferring the Cooperative shares or assigning the proprietary lease.
The approval or consent is usually based on the prospective purchaser's income
and net worth, among other factors, and may significantly reduce the number of
potential purchasers, which could limit the ability of the lender to sell and
realize upon the value of the collateral. Generally, the lender is not limited
in any rights it may have to dispossess the tenant-stockholder.

         Because of the nature of cooperative mortgage loans, lenders do not
require the tenant-stockholder (i.e., the borrower) to obtain title insurance of
any type. Consequently, the existence of any prior liens or other imperfections
of title affecting the Cooperative's building or real estate also may adversely
affect the marketability of the shares allocated to the dwelling unit in the
event of foreclosure.

         In New York, foreclosure on the Cooperative shares is accomplished by
public sale in accordance with the provisions of Article 9 of the New York UCC
and the security agreement relating to those shares. Article 9 of the New York
UCC requires that a sale be conducted in a "commercially reasonable" manner.
Whether a sale has been conducted in a "commercially reasonable" manner will
depend on the facts in each case. In determining commercial reasonableness, a
court will look to the notice given the debtor and the method, manner, time,
place and terms of the sale and the sale price. Generally, a sale conducted
according to the usual practice of banks selling similar collateral in the same
area will be considered reasonably conducted.

         Article 9 of the UCC provides that the proceeds of the sale will be
applied first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's



                                     - 93 -


security interest. The recognition agreement, however, generally provides that
the lender's right to reimbursement is subject to the right of the Cooperative
corporation to receive sums due under the proprietary lease or occupancy
agreement. If there are proceeds remaining, the lender must account to the
tenant-stockholder for the surplus. Conversely, if a portion of the indebtedness
remains unpaid, the tenant-stockholder is generally responsible for the
deficiency. See "--Anti-Deficiency Legislation and other Limitations on Lenders"
below.

REPOSSESSION WITH RESPECT TO CONTRACTS

         GENERAL. Repossession of manufactured housing is governed by state law.
A few states have enacted legislation that requires that the debtor be given an
opportunity to cure its default (typically 30 days to bring the account current)
before repossession can commence. So long as a manufactured home has not become
so attached to real estate that it would be treated as a part of the real estate
under the law of the state where it is located, repossession of the home in the
event of a default by the obligor generally will be governed by the UCC (except
in Louisiana). Article 9 of the UCC provides the statutory framework for the
possession of manufactured housing. While the UCC as adopted by the various
states may vary in small particulars, the general repossession procedure
established by the UCC is as follows:

         o        Except in those states where the debtor must receive notice of
                  the right to cure a default, repossession can commence
                  immediately upon default without prior notice. Repossession
                  may be effected either through self-help (peaceable retaking
                  without court order), voluntary repossession or through
                  judicial process (repossession pursuant to court-issued writ
                  of replevin). The self-help and/or voluntary repossession
                  methods are more commonly employed, and are accomplished
                  simply by retaking possession of the manufactured home. In
                  cases in which the debtor objects or raises a defense to
                  repossession, a court order must be obtained from the
                  appropriate state court, and the manufactured home must then
                  be repossessed in accordance with that order. Whether the
                  method employed is self-help, voluntary repossession or
                  judicial repossession, the repossession can be accomplished
                  either by an actual physical removal of the manufactured home
                  to a secure location for refurbishment and resale or by
                  removing the occupants and their belongings from the
                  manufactured home and maintaining possession of the
                  manufactured home on the location where the occupants were
                  residing. Various factors may affect whether the manufactured
                  home is physically removed or left on location, such as the
                  nature and term of the lease of the site on which it is
                  located and the condition of the unit. In many cases, leaving
                  the manufactured home on location is preferable, in the event
                  that the home is already set up, because the expenses of
                  retaking and redelivery will be saved. However, in those cases
                  where the home is left on location, expenses for site rentals
                  will usually be incurred.

         o        Once repossession has been achieved, preparation for the
                  subsequent disposition of the manufactured home can commence.
                  The disposition may be by public or private sale provided the
                  method, manner, time, place and terms of the sale are
                  commercially reasonable.

                                     - 94 -



         o        Sale proceeds are to be applied first to repossession expenses
                  (expenses incurred in retaking, storage, preparing for sale to
                  include refurbishing costs and selling) and then to
                  satisfaction of the indebtedness. While some states impose
                  prohibitions or limitations on deficiency judgments if the net
                  proceeds from resale do not cover the full amount of the
                  indebtedness, the remainder may be sought from the debtor in
                  the form of a deficiency judgement in those states that do not
                  prohibit or limit the judgments. The deficiency judgment is a
                  personal judgment against the debtor for the shortfall.
                  Occasionally, after resale of a manufactured home and payment
                  of all expenses and indebtedness, there is a surplus of funds.
                  In that case, the UCC requires the party suing for the
                  deficiency judgment to remit the surplus to the debtor.
                  Because the defaulting owner of a manufactured home generally
                  has very little capital or income available following
                  repossession, a deficiency judgment may not be sought in many
                  cases or, if obtained, will be settled at a significant
                  discount in light of the defaulting owner's strained financial
                  condition.

         LOUISIANA LAW. Any contract secured by a manufactured home located in
Louisiana will be governed by Louisiana law rather than Article 9 of the UCC.
Louisiana laws provide similar mechanisms for perfection and enforcement of
security interests in manufactured housing used as collateral for an installment
sale contract or installment loan agreement.

         Under Louisiana law, a manufactured home that has been permanently
affixed to real estate will nevertheless remain subject to the motor vehicle
registration laws unless the obligor and any holder of a security interest in
the property execute and file in the real estate records for the parish in which
the property is located a document converting the unit into real property. A
manufactured home that is converted into real property but is then removed from
its site can be converted back to personal property governed by the motor
vehicle registration laws if the obligor executes and files various documents in
the appropriate real estate records and all mortgagees under real estate
mortgages on the property and the land to which it was affixed file releases
with the motor vehicle commission.

         So long as a manufactured home remains subject to the Louisiana motor
vehicle laws, liens are recorded on the certificate of title by the motor
vehicle commissioner and repossession can be accomplished by voluntary consent
of the obligor, executory process (repossession proceedings which must be
initiated through the courts but which involve minimal court supervision) or a
civil suit for possession. In connection with a voluntary surrender, the obligor
must be given a full release from liability for all amounts due under the
contract. In executory process repossessions, a sheriff's sale (without court
supervision) is permitted, unless the obligor brings suit to enjoin the sale,
and the lender is prohibited from seeking a deficiency judgment against the
obligor unless the lender obtained an appraisal of the manufactured home prior
to the sale and the property was sold for at least two-thirds of its appraised
value.

RIGHTS OF REDEMPTION

         SINGLE FAMILY, MULTIFAMILY AND COMMERCIAL PROPERTIES. The purposes of a
foreclosure action in respect of a mortgaged property is to enable the lender to
realize upon its security and



                                     - 95 -


to bar the borrower, and all persons who have interests in the property that are
subordinate to that of the foreclosing lender, from exercise of their "equity of
redemption". The doctrine of equity of redemption provides that, until the
property encumbered by a mortgage has been sold in accordance with a properly
conducted foreclosure and foreclosure sale, those having interests that are
subordinate to that of the foreclosing lender have an equity of redemption and
may redeem the property by paying the entire debt with interest. Those having an
equity of redemption must generally be made parties and joined in the
foreclosure proceeding in order for their equity of redemption to be terminated.

         The equity of redemption is a common-law (non-statutory) right which
should be distinguished from post-sale statutory rights of redemption. In some
states, after sale pursuant to a deed of trust or foreclosure of a mortgage, the
borrower and foreclosed junior lienors are given a statutory period in which to
redeem the property. In some states, statutory redemption may occur only upon
payment of the foreclosure sale price. In other states, redemption may be
permitted if the former borrower pays only a portion of the sums due. The effect
of a statutory right of redemption is to diminish the ability of the lender to
sell the foreclosed property because the exercise of a right of redemption would
defeat the title of any purchase through a foreclosure. Consequently, the
practical effect of the redemption right is to force the lender to maintain the
property and pay the expenses of ownership until the redemption period has
expired. In some states, a post-sale statutory right of redemption may exist
following a judicial foreclosure, but not following a trustee's sale under a
deed of trust.

         MANUFACTURED HOMES. While state laws do not usually require notice to
be given to debtors prior to repossession, many states do require delivery of a
notice of default and of the debtor's right to cure defaults before
repossession. The law in most states also requires that the debtor be given
notice of sale prior to the resale of the home so that the owner may redeem at
or before resale. In addition, the sale must comply with the requirements of the
UCC.

ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS

         SINGLE FAMILY, MULTIFAMILY AND COMMERCIAL LOANS. Some states have
imposed statutory prohibitions which limit the remedies of a beneficiary under a
deed of trust or a mortgagee under a mortgage. In some states (including
California), statutes limit the right of the beneficiary or mortgagee to obtain
a deficiency judgment against the borrower following non-judicial foreclosure by
power of sale. A deficiency judgment is a personal judgment against the former
borrower equal in most cases to the difference between the net amount realized
upon the public sale of the real property and the amount due to the lender. In
the case of a mortgage loan secured by a property owned by a trust where the
mortgage note is executed on behalf of the trust, a deficiency judgment against
the trust following foreclosure or sale under a deed of trust, even if
obtainable under applicable law, may be of little value to the mortgagee or
beneficiary if there are no trust assets against which the deficiency judgment
may be executed. Some state statutes require the beneficiary or mortgagee to
exhaust the security afforded under a deed of trust or mortgage by foreclosure
in an attempt to satisfy the full debt before bringing a personal action against
the borrower. In other states, the lender has the option of bringing a personal
action against the borrower on the debt without first exhausting the security;
however in some of these states, the lender, following judgment on the personal
action, may be deemed to have elected a



                                     - 96 -


remedy and may be precluded from exercising remedies with respect to the
security. Consequently, the practical effect of the election requirement, in
those states permitting the election, is that lenders will usually proceed
against the security first rather than bringing a personal action against the
borrower. Finally, in some states, statutory provisions limit any deficiency
judgment against the former borrower following a foreclosure to the excess of
the outstanding debt over the fair value of the property at the time of the
public sale. The purpose of these statutes is generally to prevent a beneficiary
or mortgagee from obtaining a large deficiency judgment against the former
borrower as a result of low or no bids at the judicial sale.

         Generally, Article 9 of the UCC governs foreclosure on Cooperative
Shares and the related proprietary lease or occupancy agreement. Some courts
have interpreted Article 9 to prohibit or limit a deficiency award in some
circumstances, including circumstances where the disposition of the collateral
(which, in the case of a cooperative mortgage loan, would be the shares of the
Cooperative and the related proprietary lease or occupancy agreement) was not
conducted in a commercially reasonable manner.

         In addition to laws limiting or prohibiting deficiency judgments,
numerous other federal and state statutory provisions, including the federal
bankruptcy laws and state laws affording relief to debtors, may interfere with
or affect the ability of the secured mortgage lender to realize upon collateral
or enforce a deficiency judgment. For example, under the federal Bankruptcy
Code, virtually all actions (including foreclosure actions and deficiency
judgment proceedings) to collect a debt are automatically stayed upon the filing
of the bankruptcy petition and, often, no interest or principal payments are
made during the course of the bankruptcy case. The delay and the consequences
thereof caused by the automatic stay can be significant. Also, under the
Bankruptcy Code, the filing of a petition in a bankruptcy by or on behalf of a
junior lien or may stay the senior lender from taking action to foreclose out
the junior lien. Moreover, with respect to federal bankruptcy law, a court with
federal bankruptcy jurisdiction may permit a debtor through his or her Chapter
11 or Chapter 13 rehabilitative plan to cure a monetary default in respect of a
mortgage loan on a debtor's residence by paying arrearage within a reasonable
time period and reinstating the original mortgage loan payment schedule even
though the lender accelerated the mortgage loan and final judgment of
foreclosure had been entered in state court (provided no sale of the residence
had yet occurred) prior to the filing of the debtor's petition. Some courts with
federal bankruptcy jurisdiction have approved plans, based on the particular
facts of the reorganization case, that effected the curing of a mortgage loan
default by paying arrearage over a number of years.

         Courts with federal bankruptcy jurisdiction have also indicated that
the terms of a mortgage loan secured by property of the debtor may be modified.
These courts have allowed modifications that include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
forgiving all or a portion of the debt and reducing the lender's security
interest to the value of the residence, thus leaving the lender a general
unsecured creditor for the difference between the value of the residence and the
outstanding balance of the loan. Generally, however, the terms of a mortgage
loan secured only by a mortgage on real property that is the debtor's principal
residence may not be modified pursuant to a plan confirmed pursuant to Chapter
13 except with respect to mortgage payment arrearages, which may be cured within
a reasonable time period.

                                     - 97 -


         In the case of income-producing multifamily properties, federal
bankruptcy law may also have the effect of interfering with or affecting the
ability of the secured lender to enforce the borrower's assignment of rents and
leases related to the mortgaged property. Under Section 362 of the Bankruptcy
Code, the lender will be stayed from enforcing the assignment, and the legal
proceedings necessary to resolve the issue could be time-consuming, with
resulting delays in the lender's receipt of the rents.

         Tax liens arising under the Code may have priority over the lien of a
mortgage or deed of trust. In addition, substantive requirements are imposed
upon mortgage lenders in connection with the origination and the servicing of
mortgage loans by numerous federal and some state consumer protection laws.
These laws include the federal Truth-in-Lending Act ("TILA"), Real Estate
Settlement Procedures Act ("RESPA"), Equal Credit Opportunity Act ("ECOA"), Fair
Credit Billing Act ("FCBA"), Fair Credit Reporting Act ("FCRA") and related
statutes. These federal laws impose specific statutory liabilities upon lenders
who originate mortgage loans and who fail to comply with the provisions of the
law. In some cases, this liability may affect assignees of the mortgage loans.

         CONTRACTS. In addition to the laws limiting or prohibiting deficiency
judgments, numerous other statutory provisions, including federal bankruptcy
laws and related state laws, may interfere with or affect the ability of a
lender to realize upon collateral and/or enforce a deficiency judgment. For
example, in a Chapter 13 proceeding under the federal bankruptcy law, a court
may prevent a lender from repossessing a home, and, as part of the
rehabilitation plan, reduce the amount of the secured indebtedness to the market
value of the home at the time of bankruptcy (as determined by the court),
leaving the party providing financing as a general unsecured creditor for the
remainder of the indebtedness. A bankruptcy court may also reduce the monthly
payments due under a contract or change the rate of interest and time of
repayment of the indebtedness.

ENVIRONMENTAL LEGISLATION

         Under CERCLA, and under state law in some states, a secured party which
takes a deed-in-lieu of foreclosure, purchases a mortgaged property at a
foreclosure sale, or operates a mortgaged property may become liable for the
costs of cleaning up hazardous substances regardless of whether they have
contaminated the property. CERCLA imposes strict, as well as joint and several,
liability on several classes of potentially responsible parties, including
current owners and operators of the property who did not cause or contribute to
the contamination. Furthermore, liability under CERCLA is not limited to the
original or unamortized principal balance of a loan or to the value of the
property securing a loan. Lenders may be held liable under CERCLA as owners or
operators unless they qualify for the secured creditor exemption to CERCLA. This
exemption exempts from the definition of owners and operators those who, without
participating in the management of a facility, hold indicia of ownership
primarily to protect a security interest in the facility.

         The Conservation Act amended, among other things, the provisions of
CERCLA with respect to lender liability and the secured creditor exemption. The
Conservation Act offers substantial protection to lenders by defining the
activities in which a lender can engage and still



                                     - 98 -


have the benefit of the secured creditor exemption. In order for lender to be
deemed to have participated in the management of a mortgaged property, the
lender must actually participate in the operational affairs of the property of
the borrower. The Conservation Act provides that "merely having the capacity to
influence, or unexercised right to control" operations does not constitute
participation in management. A lender will lose the protection of the secured
creditor exemption only if it exercises decision-making control over the
borrower's environmental compliance and hazardous substance handling and
disposal practices, or assumes day-to-day management of all operational
functions of the mortgaged property. The Conservation Act also provides that a
lender will continue to have the benefit of the secured creditor exemption even
if it forecloses on a mortgaged property, purchases it at a foreclosure sale or
accepts a deed-in-lieu of foreclosure provided that the lender seeks to sell the
mortgaged property at the earliest practicable commercially reasonable time on
commercially reasonable terms.

         Other federal and state laws may impose liability on a secured party
which takes a deed-in-lieu of foreclosure, purchases a mortgaged property at a
foreclosure sale, or operates a mortgaged property on which contaminants other
than CERCLA hazardous substances are present, including petroleum, agricultural
chemicals, hazardous wastes, asbestos, radon, and lead-based paint. The cleanup
costs may be substantial. It is possible that the cleanup costs could become a
liability of a trust fund and reduce the amounts otherwise distributable to the
holders of the related series of certificates. Moreover, federal statutes and
states by statute may impose a lien for any cleanup costs incurred by the state
on the property that is the subject of the cleanup costs. All subsequent liens
on the property generally are subordinated to the lien and, in some states, even
prior recorded liens are subordinated to such lien. In the latter states, the
security interest of the trustee in a related parcel of real property that is
subject to the lien could be adversely affected.

         Traditionally, many residential mortgage lenders have not taken steps
to evaluate whether contaminants are present with respect to any mortgaged
property prior to the origination of the mortgage loan or prior to foreclosure
or accepting a deed-in-lieu of foreclosure. Accordingly, the depositor has not
made and will not make the evaluations prior to the origination of the Secured
Contracts. Neither the depositor nor any replacement Servicer will be required
by any Agreement to undertake these evaluations prior to foreclosure or
accepting a deed-in-lieu of foreclosure. The depositor does not make any
representations or warranties or assume any liability with respect to the
absence or effect of contaminants on any related real property or any casualty
resulting from the presence or effect of contaminants. However, the depositor
will not be obligated to foreclose on related real property or accept a
deed-in-lieu of foreclosure if it knows or reasonably believes that there are
material contaminated conditions on the property. A failure so to foreclose may
reduce the amounts otherwise available to certificateholders of the related
series.

CONSUMER PROTECTION LAWS WITH RESPECT TO CONTRACTS

         In addition, substantive requirements are imposed upon mortgage lenders
in connection with the origination and the servicing of mortgage loans by
numerous federal and some state consumer protection laws. These laws include
TILA, as implemented by Regulation Z, RESPA, as implemented by Regulation X,
ECOA, as implemented by Regulation B, FCBA, FCRA and



                                     - 99 -


related statutes. These federal laws impose specific statutory liabilities upon
lenders who originate mortgage loans and who fail to comply with the provisions
of the law. In some cases, this liability may affect assignees of the mortgage
loans. In particular, an originator's failure to comply with certain
requirements of the federal TILA, as implemented by Regulation Z, could subject
both originators and assignees of such obligations to monetary penalties and
could result in obligors' rescinding the mortgage loans either against the
originators or assignees.

         Some of the mortgage loans, known as High Cost Loans, may be subject to
the Homeownership Act, which amended TILA to provide new requirements applicable
to loans that exceed certain interest rates and/or points and fees thresholds.
Purchasers or assignees of any High Cost Loan, including any trust, could be
liable under federal law for all claims and subject to all defenses that the
borrower could assert against the originator of the High Cost Loan. Remedies
available to the borrower include monetary penalties, as well as rescission
rights if the appropriate disclosures were not given as required. The maximum
damages that may be recovered under these provisions from an assignee, including
the trust, is the remaining amount of indebtedness plus the total amount paid by
the borrower in connection with the mortgage loan.

         In addition to the Homeownership Act, a number of legislative proposals
have been introduced at both the federal and state level that are designed to
discourage predatory lending practices. Some states have enacted, or may enact,
laws or regulations that prohibit inclusion of some provisions in mortgage loans
that have interest rates or origination costs in excess of prescribed levels,
and require that borrowers be given certain disclosures prior to the
consummation of the mortgage loans. In some cases, state law may impose
requirements and restrictions greater than those in the Homeownership Act. An
originators' failure to comply with these laws could subject the trust (and
other assignees of the mortgage loans) to monetary penalties and could result in
the borrowers rescinding the mortgage loans against either the trust or
subsequent holders of the mortgage loans.

         Lawsuits have been brought in various states making claims against
assignees of High Cost Loans for violations of state law allegedly committed by
the originator. Named defendants in these cases include numerous participants
within the secondary mortgage market, including some securitization trusts.

         Manufactured housing contracts often contain provisions obligating the
obligor to pay late charges if payments are not timely made. Federal and state
law may specifically limit the amount of late charges that may be collected.
Under the related pooling and servicing agreement or servicing agreement, late
charges will be retained by the master servicer as additional servicing
compensation, and any inability to collect these amounts will not affect
payments to Certificateholders.

         Courts have imposed general equitable principles upon repossession and
litigation involving deficiency balances. These equitable principles are
generally designed to relieve a consumer from the legal consequences of a
default.

         In several cases, consumers have asserted that the remedies provided to
secured parties under the UCC and related laws violate the due process
protections provided under the 14th Amendment to the Constitution of the United
States. For the most part, courts have upheld the



                                    - 100 -


notice provisions of the UCC and related laws as reasonable or have found that
the repossession and resale by the creditor does not involve sufficient state
action to afford constitutional protection to consumers.

         The FTC Rule has the effect of subjecting a seller (and some related
creditors and their assignees) in a consumer credit transaction and any assignee
of the creditor to all claims and defenses which the debtor in the transaction
could assert against the seller of the goods. Liability under the FTC Rule is
limited to the amounts paid by a debtor on the contract, and the holder of the
contract may also be unable to collect amounts still due under the contract.
Most of the Contracts in a trust fund will be subject to the requirements of the
FTC Rule. Accordingly, the trust fund, as holder of the Contracts, will be
subject to any claims or defenses that the purchaser of the related manufactured
home may assert against the seller of the manufactured home, subject to a
maximum liability equal to the amounts paid by the obligor on the Contract. If
an obligor is successful in asserting the claim or defense, and if the Seller
had or should have had knowledge of the claim or defense, the master servicer
will have the right to require the Seller to repurchase the Contract because of
breach of its Seller's representation and warranty that no claims or defenses
exist that would affect the obligor's obligation to make the required payments
under the Contract. The Seller would then have the right to require the
originating dealer to repurchase the Contract from it and might also have the
right to recover from the dealer any losses suffered by the Seller with respect
to which the dealer would have been primarily liable to the obligor.

ENFORCEABILITY OF SOME PROVISIONS

         TRANSFER OF MORTGAGED PROPERTIES. Unless the related prospectus
supplement indicates otherwise, the mortgage loans generally contain due-on-sale
clauses. These clauses permit the lender to accelerate the maturity of the loan
if the borrower sells, transfers or conveys the property without the prior
consent of the lender. The enforceability of these clauses has been the subject
of legislation or litigation in many states, and in some cases the
enforceability of these clauses was limited or denied. However, Garn-St Germain
Act preempts state constitutional, statutory and case law that prohibits the
enforcement of due-on-sale clauses and permits lenders to enforce these clauses
in accordance with their terms, subject to limited exceptions. The Garn-St
Germain Act does "encourage" lenders to permit assumption of loans at the
original rate of interest or at some other rate less than the average of the
original rate and the market rate.

         The Gain-St Germain Act also sets forth nine specific instances in
which a mortgage lender covered by the Gain-St Germain Act may not exercise a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have occurred. These include intra-family transfers, some transfers by operation
of law, leases of fewer than three years and the creation of a junior
encumbrance. Regulations promulgated under the Gain-St Germain Act also prohibit
the imposition of a prepayment penalty upon the acceleration of a loan pursuant
to a due-on-sale clause.

         The inability to enforce a due-on-sale clause may result in a mortgage
loan bearing an interest rate below the current market rate being assumed by the
buyer rather than being paid off,



                                    - 101 -


which may have an impact upon the average life of the mortgage loans and the
number of mortgage loans which may be outstanding until maturity.

         TRANSFER OF MANUFACTURED HOMES. Generally, manufactured housing
contracts contain provisions prohibiting the sale or transfer of the related
manufactured homes without the consent of the obligee on the contract and
permitting the acceleration of the maturity of the contracts by the obligee on
the contract upon the sale or transfer that is not consented to. The master
servicer will, to the extent it has knowledge of the conveyance or proposed
conveyance, exercise or cause to be exercised its rights to accelerate the
maturity of the related Contracts through enforcement of due-on-sale clauses,
subject to applicable state law. In some cases, the transfer may be made by a
delinquent obligor in order to avoid a repossession proceeding with respect to a
Manufactured Home.

         In the case of a transfer of a Manufactured Home as to which the master
servicer desires to accelerate the maturity of the related Contract, the master
servicer's ability to do so will depend on the enforceability under state law of
the due-on-sale clause. The Gain-St Germain Act preempts, subject to certain
exceptions and conditions, state laws prohibiting enforcement of due-on-sale
clauses applicable to the Manufactured Homes. Consequently, in some cases
teamster servicer may be prohibited from enforcing a due-on-sale clause in
respect of a Manufactured Home.

         LATE PAYMENT CHARGES AND PREPAYMENT RESTRICTIONS. Notes and mortgages,
as well as manufactured housing conditional sales contracts and installment loan
agreements, may contain provisions that obligate the borrower to pay a late
charge or additional interest if payments are not timely made, and in some
circumstances, may prohibit prepayments for a specified period and/or condition
prepayments upon the borrower's payment of prepayment fees or yield maintenance
penalties. In some states, there are or may be specific limitations upon the
late charges which a lender may collect from a borrower for delinquent payments
or the amounts that a lender may collect from a borrower as an additional charge
if the loan is prepaid even when the loans expressly provide for the collection
of those charges. Although the Parity Act permits the collection of prepayment
charges and late fees in connection with some types of eligible loans preempting
any contrary state law prohibitions, some states may not recognize the
preemptive authority of the Parity Act or have formally opted out of the Parity
Act. As a result, it is possible that prepayment charges and late fees may not
be collected even on loans that provide for the payment of those charges unless
otherwise specified in the accompanying prospectus supplement. The master
servicer or another entity identified in the accompanying prospectus supplement
will be entitled to all prepayment charges and late payment charges received on
the loans and those amounts will not be available for payment on the bonds. The
Office of Thrift Supervision (OTS), the agency that administers the Parity Act
for unregulated housing creditors, withdrew its favorable Parity Act regulations
and Chief Counsel Opinions that previously authorized lenders to charge
prepayment charges and late fees in certain circumstances notwithstanding
contrary state law, effective with respect to loans originated on or after July
1, 2003. However, the OTS's ruling does not retroactively affect loans
originated before July 1, 2003.

                                    - 102 -


SUBORDINATE FINANCING

         When the mortgagor encumbers mortgaged property with one or more junior
liens, the senior lender is subjected to additional risk. First, the mortgagor
may have difficulty servicing and repaying multiple loans. In addition, if the
junior loan permits recourse to the mortgagor (as junior loans often do) and the
senior loan does not, a mortgagor may be more likely to repay sums due on the
junior loan than those on the senior loan. Second, acts of the senior lender
that prejudice the junior lender or impair the junior lender's security may
create a superior equity in favor of the junior lender. For example, if the
mortgagor and the senior lender agree to an increase in the principal amount of
or the interest rate payable on the senior loan, the senior lender may lose its
priority to the extent an existing junior lender is harmed or the mortgagor is
additionally burdened. Third, if the mortgagor defaults on the senior loan
and/or any junior loan or loans, the existence of junior loans and actions taken
by junior lenders can impair the security available to the senior lender and can
interfere with or delay the taking of action by the senior lender. Moreover, the
bankruptcy of a junior lender may operate to stay foreclosure or similar
proceedings by the senior lender.

INSTALLMENT CONTRACTS

         The trust fund assets may also consist of installment sales contracts.
Under an installment contract the seller (referred to in this section as the
"lender") retains legal title to the property and enters into an agreement with
the purchaser (referred to in this section as the "borrower") for the payment of
the purchase price, plus interest, over the term of the contract. Only after
full performance by the borrower of the installment contract is the lender
obligated to convey title to the property to the purchaser. As with mortgage or
deed of trust financing, during the effective period of the installment
contract, the borrower is generally responsible for the maintaining the property
in good condition and for paying real estate taxes, assessments and hazard
insurance premiums associated with the property.

         The method of enforcing the rights of the lender under an installment
contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to its terms. The terms of installment contracts
generally provide that upon a default by the borrower, the borrower loses his or
her right to occupy the property, the entire indebtedness is accelerated and the
buyer's equitable interest in the property is forfeited. The lender in this
situation is not required to foreclose in order to obtain title to the property,
although in some cases a quiet title action is in order if the borrower has
filed the installment contract in local land records and an ejectment action
maybe necessary to recover possession. In a few states, particularly in cases of
borrower default during the early years of an installment contract, the courts
will permit ejectment of the buyer and a forfeiture of his or her interest in
the property. However, most state legislatures have enacted provisions by
analogy to mortgage law protecting borrowers under installment contracts from
the harsh consequences of forfeiture. Under these statutes, a judicial or
nonjudicial foreclosure may be required, the lender may be required to give
notice of default and the borrower may be granted some grace period during which
the installment contract may be reinstated upon full payment of the defaulted
amount and the borrower may have a post-foreclosure statutory redemption right.
In other states, courts in equity may permit a borrower with significant


                                    - 103 -


investment in the property under an installment contract for the sale of real
estate to share in the proceeds of sale of the property after the indebtedness
is repaid or may otherwise refuse to enforce the forfeiture clause.
Nevertheless, the lender's procedures for obtaining possession and clear title
under an installment contract in a given state are simpler and less time
consuming and costly than are the procedures for foreclosing and obtaining clear
title to a property subject to one or more liens.

APPLICABILITY OF USURY LAWS

         Title V provides that state usury limitations shall not apply to some
types of residential first mortgage loans originated by some lenders after March
31,1980. A similar federal statute was in effect with respect to mortgage loans
made during the first three months of 1980. The Office of Thrift Supervision is
authorized to issue rules and regulations and to publish interpretations
governing implementation of Title V. The statute authorized any state to
reimpose interest rate limits by adopting, before April 1, 1983, a law or
constitutional provision which expressly rejects application of the federal law.
In addition, even where Title V is not so rejected, any state is authorized by
the law to adopt a provision limiting discount points or other charges on
mortgage loans covered by Title V. Some states have taken action to reimpose
interest rate limits or to limit discount points or other charges.

         Title V also provides that, subject to the following conditions, state
usury limitations shall not apply to any loan that is secured by a first lien on
some kinds of manufactured housing. Contracts would be covered if they satisfy
conditions including, among other things, terms governing any prepayments, late
charges and deferral fees and requiring a 30-day notice period prior to
instituting any action leading to repossession of or foreclosure with respect to
the related unit. Title V authorized any state to reimpose limitations on
interest rates and finance charges by adopting before April 1,1983 a law or
constitutional provision which expressly rejects application of the federal law.
Fifteen states adopted this type of law prior to the April 1,1983 deadline. In
addition, even where Title V was not so rejected, any state is authorized by the
law to adopt a provision limiting discount points or other charges on loans
covered by Title V. In any state in which application of Title V was expressly
rejected or a provision limiting discount points or other charges has been
adopted, no Contract which imposes finance charges or provides for discount
points or charges in excess of permitted levels has been included in the trust
fund.

         Usury limits apply to junior mortgage loans in many states. Any
applicable usury limits in effect at origination will be reflected in the
maximum mortgage rates for ARM Loans, as set forth in the related prospectus
supplement.

         As indicated above under "The Mortgage Pools--Representations by
Sellers," each Seller of a mortgage loan will have represented that the mortgage
loan was originated in compliance with then applicable state laws, including
usury laws, in all material respects. However, the mortgage rates on the
mortgage loans will be subject to applicable usury laws as in effect from time
to time.

ALTERNATIVE MORTGAGE INSTRUMENTS

         Alternative mortgage instruments, including adjustable rate mortgage
loans and early ownership mortgage loans, originated by non-federally chartered
lenders historically have been subjected to a variety of restrictions. The
restrictions differed from state to state, resulting in difficulties in
determining whether a particular alternative mortgage instrument originated by a
state-chartered lender was in compliance with applicable law. These difficulties
were alleviated substantially as a result of the enactment of Title VIII. Title
VIII provides that, notwithstanding any state law to the contrary, (1)
state-chartered banks may originate alternative mortgage instruments in
accordance with regulations promulgated by the Comptroller of the Currency with
respect to origination of alternative mortgage instruments by national banks,
(2) state-chartered credit unions may originate alternative mortgage instruments
in accordance with regulations promulgated by the National Credit Union
Administration with respect to origination of alternative mortgage instruments
by federal credit unions, and (3) all other non-federally chartered housing
creditors, including state-chartered savings and loan associations,
state-chartered savings banks and mutual savings banks and mortgage banking
companies, may originate alternative mortgage instruments in accordance with the
regulations promulgated by the Federal Home Loan Bank Board, predecessor to the
Office of Thrift Supervision, with respect to origination of alternative
mortgage instruments by federal savings and loan associations. Title VIII
provides that any state may reject applicability of the provisions of Title VIII
by adopting, prior to October 15, 1985, a law or constitutional provision
expressly rejecting the applicability of the provisions. Some states have taken
this action.

FORMALDEHYDE LITIGATION WITH RESPECT TO CONTRACTS

         A number of lawsuits are pending in the United States alleging personal
injury from exposure to the chemical formaldehyde, which is present in many
building materials, including components of manufactured housing such as plywood
flooring and wall paneling. Some of these lawsuits are pending against
manufacturers of manufactured housing, suppliers of component parts, and related
persons in the distribution process. The depositor is aware of a limited number
of cases in which plaintiffs have won judgments in these lawsuits.

         Under the FTC Rule, which is described above under "Consumer Protection
Laws", the holder of any Contract secured by a Manufactured Home with respect to
which a formaldehyde claim has been successfully asserted may be liable to the
obligor for the amount paid by the obligor on the related Contract and may be
unable to collect amounts still due under the Contract. In the event an obligor
is successful in asserting this claim, the related certificateholders could
suffer a loss if (1) the related Seller fails or cannot be required to
repurchase the affected Contract for a breach of representation and warranty and
(2) the master servicer or the trustee were unsuccessful in asserting any claim
of contribution or subornation on behalf of the Certificateholders against the
manufacturer or other persons who were directly liable to the plaintiff for the
damages. Typical products liability insurance policies held by manufacturers and
component suppliers of manufactured homes may not cover liabilities arising from
formaldehyde in manufactured housing, with the result that recoveries from these
manufacturers, suppliers or other persons may be limited to their corporate
assets without the benefit of insurance.

                                    - 105 -


SERVICEMEMBERS' CIVIL RELIEF ACT OF 1940

         Under the terms of the Relief Act, a mortgagor who enters military
service after the origination of the mortgagor's mortgage loan (including a
mortgagor who was in reserve status and is called to active duty after
origination of the mortgage loan), may not be charged interest (including fees
and charges) above an annual rate of 6% during the period of the mortgagor's
active duty status, unless a court orders otherwise upon application of the
lender. A court may grant a lender relief from the requirements of the Relief
Act if, in the court's opinion, the servicemember's ability to pay interest upon
the loan at a rate in excess of 6% percent is not materially affected by reason
of the servicemembers' military service. The Relief Act applies to mortgagors
who are members of the Army, Navy, Air Force, Marines, National Guard, Reserves,
Coast Guard, officers of the U.S. Public Health Service, officers of the
National Oceanic and Atmosphere Administration and draftees under an induction
order assigned to duty with the military. Because the Relief Act applies to
mortgagors who enter military service, including reservists who are called to
active duty, after origination of the related mortgage loan, no information can
be provided as to the number of loans that may be affected by the Relief Act.
Application of the Relief Act would adversely affect, for an indeterminate
period of time, the ability of the master servicer to collect full amounts of
interest on the mortgage loans subject to the Relief Act. Any shortfall in
interest collections resulting from the application of the Relief Act or similar
legislation or regulations, which would not be recoverable from the related
mortgage loans, would result in a reduction of the amounts distributable to the
holders of the related securities, and would not be covered by advances by the
master servicer or other entity or by any form of credit enhancement provided in
connection with the related series of securities, unless described in the
prospectus supplement. In addition, the Relief Act imposes limitations that
would impair the ability of the master servicer to foreclose on an affected
single family loan or enforce rights under a Contract during the mortgagor's
period of active duty status, and, under some circumstances, during an
additional three month period thereafter. Thus, in the event that the Relief
Actor similar legislation or regulations applies to any mortgage loan which goes
into default, there may be delays in payment and losses on the related
securities in connection therewith. Any other interest shortfalls, deferrals or
forgiveness of payments on the mortgage loans resulting from similar legislation
or regulations may result in delays in payments or losses to certificateholders
of the related series.

FORFEITURES IN DRUG AND RICO PROCEEDINGS

         Federal law provides that property owned by persons convicted of
drug-related crimes or of criminal violations of RICO can be seized by the
government if the property was used in, or purchased with the proceeds of, these
crimes. Under procedures contained in the Crime Control Act, the government may
seize the property even before conviction. The government must publish notice of
the forfeiture proceeding and may give notice to all parties "known to have an
alleged interest in the property", including the holders of mortgage loans.

         A lender may avoid forfeiture of its interest in the property if it
establishes that: (1) its mortgage was executed and recorded before commission
of the crime upon which the forfeiture is based, or (2) the lender was, at the
time of execution of the mortgage, "reasonably without



                                    - 106 -


cause to believe" that the property was used in, or purchased with the proceeds
of, illegal drug or RICO activities.

         Certain states have enacted or may enact their own versions of the
Relief Act which may provide for more enhanced consumer protection provisions
than those set forth in the Relief Act. The Relief Act may not preempt those
state laws.

JUNIOR MORTGAGES

         Some of the mortgage loans may be secured by mortgages or deeds of
trust which are junior to senior mortgages or deeds of trust which are not part
of the trust fund. The rights of the certificateholders, as mortgagee under a
junior mortgage, are subordinate to those of the mortgagee under the senior
mortgage, including the prior rights of the senior mortgagee to receive hazard
insurance and condemnation proceeds and to cause the property securing the
mortgage loan to be sold upon default of the mortgagor, which may extinguish the
junior mortgagee's lien unless the junior mortgagee asserts its subordinate
interest in the property in foreclosure litigation and, in some cases, either
reinitiates or satisfies the defaulted senior loan or loans. A junior mortgagee
may satisfy a defaulted senior loan in full or, in some states, may cure the
default and bring the senior loan current thereby reinstating the senior loan,
in either event usually adding the amounts expended to the balance due on the
junior loan. In most states, absent a provision in the mortgage or deed of
trust, no notice of default is required to be given to a junior mortgagee. Where
applicable law or the terms of the senior mortgage or deed of trust do not
require notice of default to the junior mortgagee, the lack of this notice may
prevent the junior mortgagee from exercising any right to reinstate the loan
which applicable law may provide.

         The standard form of the mortgage or deed of trust used by most
institutional lenders confers on the mortgagee the right both to receive all
proceeds collected under any hazard insurance policy and all awards made in
connection with condemnation proceedings, and to apply the proceeds and awards
to any indebtedness secured by the mortgage or deed of trust, in the order the
mortgagee may determine. Thus, in the event improvements on the property are
damaged or destroyed by fire or other casualty, or in the event the property is
taken by condemnation, the mortgagee or beneficiary under underlying senior
mortgages will have the prior right to collect any insurance proceeds payable
under a hazard insurance policy and any award of damages in connection with the
condemnation and to apply the same to the indebtedness secured by the senior
mortgages. Proceeds in excess of the amount of senior mortgage indebtedness, in
most cases, may be applied to the indebtedness of junior mortgages in the order
of their priority.

         Another provision sometimes found in the form of the mortgage or deed
of trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which are prior to the mortgage
or deed of trust, to provide and maintain fire insurance on the property, to
maintain and repair the property and not to commit or permit any waste thereof,
and to appear in and defend any action or proceeding purporting to affect the
property or the rights of the mortgagee under the mortgage. Upon a failure of
the mortgagor to perform any of these



                                    - 107 -


obligations, the mortgagee or beneficiary is given the right under some
mortgages or deeds of trust to perform the obligation itself, at its election,
with the mortgagor agreeing to reimburse the mortgagee for any sums expended by
the mortgagee on behalf of the mortgagor. All sums so expended by a senior
mortgagee become part of the indebtedness secured by the senior mortgage.

NEGATIVE AMORTIZATION LOANS

         A notable case decided by the United States Court of Appeals, First
Circuit, held that state restrictions on the compounding of interest are not
preempted by the provisions of the DIDMC and as a result, a mortgage loan that
provided for negative amortization violated New Hampshire's requirement that
first mortgage loans provide for computation of interest on a simple interest
basis. The holding was limited to the effect of DIDMC on state laws regarding
the compounding of interest and the court did not address the applicability of
the Parity Act, which authorizes lender to make residential mortgage loans that
provide for negative amortization. The First Circuit's decision is binding
authority only on Federal District Courts in Maine, New Hampshire,
Massachusetts, Rhode Island and Puerto Rico.

                         FEDERAL INCOME TAX CONSEQUENCES

GENERAL

         The following discussion is the opinion of Thacher Proffitt & Wood LLP,
counsel to the depositor, with respect to the anticipated material federal
income tax consequences of the purchase, ownership and disposition of offered
securities offered under this prospectus and the prospectus supplement insofar
as it relates to matters of law or legal conclusions with respect thereto. This
discussion is directed solely to certificateholders that hold the securities as
capital assets within the meaning of Section 1221 of the Code and does not
purport to discuss all federal income tax consequences that may be applicable to
the individual circumstances of particular categories of investors, some of
which (such as banks, insurance companies and foreign investors) may be subject
special treatment under the Code. Further, the authorities on which this
discussion, and the opinion referred to below, are based are subject to change
or differing interpretations, which could apply retroactively. Prospective
investors should note that no rulings have been or will be sought from the IRS
with respect to any of the federal income tax consequences discussed below, and
no assurance can be given the IRS will not take contrary positions. Taxpayers
and preparers of tax returns (including those filed by any REMIC or other
issuing entity) should be aware that under applicable Treasury regulations a
provider of advice on specific issues of law is not considered an income tax
return preparer unless the advice (1) is given with respect to events that have
occurred at the time the advice is rendered and is not given with respect to the
consequences of contemplated actions, and (2) is directly relevant to the
determination of an entry on a tax return. Accordingly, taxpayers are encouraged
to consult their own tax advisors and tax return preparers regarding the
preparation of any item on a tax return, even where the anticipated tax
treatment has been discussed in this prospectus. In addition to the federal
income tax consequences described in this prospectus, potential investors should
consider the state and local tax consequences, if any, of the purchase,
ownership and disposition of the securities. See "State and Other Tax
Consequences."

                                    - 108 -


         The following discussion addresses securities of three general types:

         o        REMIC Certificates representing interests in a trust fund, or
                  a portion thereof, that the REMIC Administrator will elect to
                  have treated as a REMIC under the REMIC Provisions of the
                  Code,

         o        notes representing indebtedness of a trust fund as to which no
                  REMIC election will be made, and

         o        Grantor Trust Certificates representing interests in a Grantor
                  Trust Fund as to which no REMIC election will be made.

The prospectus supplement for each series of certificates will indicate whether
a REMIC election (or elections) will be made for the related trust fund and, if
this election is to be made, will identify all "regular interests" and "residual
interests" in the REMIC. For purposes of this tax discussion, references to a
"securityholder, -- certificateholder" or a "holder" are to the beneficial owner
of a security or certificate, as the case may be.

         The following discussion is based in part upon the OID Regulations and
in part upon REMIC Regulations. The OID Regulations do not adequately address
issues relevant to securities such as the offered securities. In some instances,
the OID Regulations provide that they are not applicable to securities such as
the offered securities.

REMICS

         CLASSIFICATION OF REMICS. On or prior to the date of the related
prospectus supplement with respect to the proposed issuance of each series of
REMIC Certificates, Thacher Proffitt & Wood LLP, counsel to the depositor, will
deliver its opinion generally to the effect that, assuming compliance with all
provisions of the related pooling and servicing agreement, for federal income
tax purposes, the related trust fund (or each applicable portion thereof) will
qualify as a REMIC and the REMIC Certificates offered with respect thereto will
be considered to evidence ownership of REMIC Regular Certificates or REMIC
Residual Certificates in that REMIC within the meaning of the REMIC Provisions.

         If an entity electing to be treated as a REMIC fails to comply with one
or more of the ongoing requirements of the Code for status as a REMIC during any
taxable year, the Code provides that the entity will not be treated as a REMIC
for that year and thereafter. In that event, the entity may be taxable as a
corporation under Treasury regulations, and the related REMIC Certificates may
not be accorded the status or given the tax treatment described below. Although
the Code authorizes the Treasury Department to issue regulations providing
relief in the event of an inadvertent termination of REMIC status, no such
regulations have been issued. Any such relief, moreover, may be accompanied by
sanctions, such as the imposition of a corporate tax on all or a portion of the
REMIC's income for the period in which the requirements for status as a REMIC
are not satisfied. The pooling and servicing agreement with respect to each
REMIC will include provisions designed to maintain the related trust fund's
status as a REMIC under the REMIC Provisions. It is not anticipated that the
status of any trust fund as a REMIC will be inadvertently terminated.

                                    - 109 -


         CHARACTERIZATION OF INVESTMENTS IN REMIC CERTIFICATES. In general, the
REMIC Certificates will be "real estate assets" within the meaning of Section
856(c)(4)(A) of the Code and assets described in Section 7701(a)(19)(C) of the
Code in the same proportion that the assets of the REMIC underlying the
certificates would be so treated. Moreover, if 95% or more of the assets of the
REMIC qualify for any of the foregoing treatments at all times during a calendar
year, the REMIC Certificates will qualify for the corresponding status in their
entirety for that calendar year. Interest (including original issue discount) on
the REMIC Regular Certificates and income allocated to the class of REMIC
Residual Certificates will be interest described in Section 856(c)(3)(B) of the
Code to the extent that the certificates are treated as "real estate assets"
within the meaning of Section 856(c)(4)(A) of the Code. In addition, the REMIC
Regular Certificates will be "qualified mortgages" within the meaning of Section
860G(a)(3) of the Code if transferred to another REMIC on its startup day in
exchange for regular or residual interests therein. The determination as to the
percentage of the REMIC's assets that constitute assets described in the
foregoing sections of the Code will be made with respect to each calendar
quarter based on the average adjusted basis of each category of the assets held
by the REMIC during the calendar quarter. The REMIC Administrator will report
those determinations to certificateholders in the manner and at the times
required by applicable Treasury regulations.

         The assets of the REMIC will include, in addition to mortgage loans,
payments on mortgage loans held pending distribution on the REMIC Certificates
and any property acquired by foreclosure held pending sale, and may include
amounts in reserve accounts. It is unclear whether property acquired by
foreclosure held pending sale and amounts in reserve accounts would be
considered to be part of the mortgage loans, or whether the assets (to the
extent not invested in assets described in the foregoing sections) otherwise
would receive the same treatment as the mortgage loans for purposes of all of
the Code sections mentioned in the immediately preceding paragraph. In addition,
in some instances mortgage loans may not be treated entirely as assets described
in the foregoing sections of the Code. If so, the related prospectus supplement
will describe the mortgage loans that may not be so treated. The REMIC
Regulations do provide, however, that cash received from payments on mortgage
loans held pending distribution is considered part of the mortgage loans for
purposes of Section 856(c)(4)(A) of the Code. Furthermore, foreclosure property
will qualify as "real estate assets" under Section 856(c)(4)(A) of the Code.

         TIERED REMIC STRUCTURES. For some series of REMIC Certificates, two or
more separate elections may be made to treat designated portions of the related
trust fund as REMICs for federal income tax purposes. As to each such series of
REMIC Certificates, in the opinion of counsel to the depositor, assuming with
all provisions of the related pooling and servicing agreement, each of the
REMICs in that trust fund will qualify as a REMIC and the REMIC Certificates
issued by these REMICs will be considered to evidence ownership of REMIC Regular
Certificates or REMIC Residual Certificates in the related REMIC within the
meaning of the REMIC Provisions.

         Solely for purposes of determining whether the REMIC Certificates will
be "real estate assets" within the meaning of Section 856(c)(4)(A) of the Code,
and "loans secured by an interest in real property" under Section 7701(a)(19)(C)
of the Code, and whether the income on the certificates is interest described in
Section 856(c)(3)(B) of the Code, all of the REMICs in that trust fund will be
treated as one REMIC.

         TAXATION OF OWNERS OF REMIC REGULAR CERTIFICATES.

         GENERAL. Except as otherwise stated in this discussion, REMIC Regular
Certificates will be treated for federal income tax purposes as debt instruments
issued by the REMIC and not as ownership interests in the REMIC or its assets.
Moreover, holders of REMIC Regular Certificates that otherwise report income
under a cash method of accounting will be required to report income with respect
to REMIC Regular Certificates under an accrual method.

         ORIGINAL ISSUE DISCOUNT. A REMIC Regular Certificate may be issued with
"original issue discount" within the meaning of Section 1273(a) of the Code. Any
holder of a REMIC Regular Certificate issued with original issue discount
generally will be required to include original issue discount in income as it
accrues, in accordance with the "constant yield" method described below, in
advance of the receipt of the cash attributable to that income. In addition,
Section 1272(a)(6) of the Code provides special rules applicable to REMIC
Regular Certificates and some other debt instruments issued with original issue
discount. Regulations have not been issued under that section.

         The Code requires that a reasonable prepayment assumption be used with
respect to mortgage loans held by a REMIC in computing the accrual of original
issue discount on REMIC Regular Certificates issued by that REMIC, and that
adjustments be made in the amount and rate of accrual of that discount to
reflect differences between the actual prepayment rate and the prepayment
assumption. The prepayment assumption is to be determined in a manner prescribed
in Treasury regulations; as noted above, those regulations have not been issued.
The Committee Report indicates that the regulations will provide that the
prepayment assumption used with respect to a REMIC Regular Certificate must be
the same as that used in pricing the initial offering of the REMIC Regular
Certificate. The Prepayment Assumption used in reporting original issue discount
for each series of REMIC Regular Certificates will be consistent with this
standard and will be disclosed in the related prospectus supplement. However,
none of the depositor, the master servicer or the trustee will make any
representation that the mortgage loans will in fact prepay at a rate conforming
to the Prepayment Assumption or at any other rate.

         The original issue discount, if any, on a REMIC Regular Certificate
will be the excess of its stated redemption price at maturity over its issue
price. The issue price of a particular class of REMIC Regular Certificates will
be the first cash price at which a substantial amount of REMIC Regular
Certificates of that class is sold (excluding sales to bond houses, brokers and
underwriters). If less than a substantial amount of a particular class of REMIC
Regular Certificates is sold for cash on or prior to the Closing Date, the issue
price for that class will be the fair market value of that class on the Closing
Date. Under the OID Regulations, the stated redemption price of a REMIC Regular
Certificate is equal to the total of all payments to be made on the certificate
other than "qualified stated interest. -- Qualified stated interest" is interest
that is unconditionally payable at least annually (during the entire term of the
instrument) at a single fixed rate, or at a "qualified floating rate," an
"objective rate," a combination of a single fixed rate and one or more
"qualified floating rates" or one "qualified inverse floating rate," or a
combination of "qualified floating rates" that does not operate in a manner that
accelerates or defers interest payments on the REMIC Regular Certificate.

                                    - 111 -


         In the case of REMIC Regular Certificates bearing adjustable interest
rates, the determination of the total amount of original issue discount and the
timing of the inclusion thereof will vary according to the characteristics of
the REMIC Regular Certificates. If the original issue discount rules apply to
the certificates in a particular series, the related prospectus supplement will
describe the manner in which these rules will be applied with respect to the
certificates in that series that bear an adjustable interest rate in preparing
information returns to the certificateholders and the IRS.

         The first interest payment on a REMIC Regular Certificate may be made
more than one month after the date of issuance, which is a period longer than
the subsequent monthly intervals between interest payments. Assuming the
"accrual period" (as defined below) for original issue discount is each monthly
period that ends on the day prior to each distribution date, in some cases, as a
consequence of this "long first accrual period," some or all interest payments
may be required to be included in the stated redemption price of the REMIC
Regular Certificate and accounted for as original issue discount. Because
interest on REMIC Regular Certificates must in any event be accounted for under
an accrual method, applying this analysis would result in only a slight
difference in the timing of the inclusion in income of the yield on the REMIC
Regular Certificates.

         In addition, if the accrued interest to be paid on the first
distribution date is computed with respect to a period that begins prior to the
Closing Date, a portion of the purchase price paid for a REMIC Regular
Certificate will reflect the accrued interest. In such cases, information
returns to the certificateholders and the IRS will be based on the position that
the portion of the purchase price paid for the interest accrued with respect to
periods prior to the Closing Date is treated as part of the overall cost of the
REMIC Regular Certificate (and not as a separate asset the cost of which is
recovered entirely out of interest received on the next distribution date) and
that portion of the interest paid on the first distribution date in excess of
interest accrued for a number of days corresponding to the number of days from
the Closing Date to the first distribution date should be included in the stated
redemption price of the REMIC Regular Certificate. However, the OID Regulations
state that all or some portion of the accrued interest may be treated as a
separate asset the cost of which is recovered entirely out of interest paid on
the first distribution date. It is unclear how an election to do so would be
made under the OID Regulations and whether such an election could be made
unilaterally by a certificateholder.

         Notwithstanding the general definition of original issue discount,
original issue discount on a REMIC Regular Certificate will be considered to be
de minimis if it is less than 0.25% of the stated redemption price of the REMIC
Regular Certificate multiplied by its weighted average life. For this purpose,
the weighted average life of a REMIC Regular Certificate is computed as the sum
of the amounts determined, as to each payment included in the stated redemption
price of the REMIC Regular Certificate, by multiplying (1) the number of
complete years (rounding down for partial years) from the issue date until that
payment is expected to be made (presumably taking into account the Prepayment
Assumption) by (2) a fraction, the numerator of which is the amount of the
payment, and the denominator of which is the stated redemption price at maturity
of the REMIC Regular Certificate. Under the OID Regulations, original issue
discount of only a de minimis amount (other than de minimis original issue
discount attributable to a so-called "teaser" interest rate or an initial
interest holiday) will be included in income as each payment of stated principal
is made, based on the product of the total amount of de minimis



                                    - 112 -


original issue discount attributable to that certificate and a fraction, the
numerator of which is the amount of the principal payment and the denominator of
which is the outstanding stated principal amount of the REMIC Regular
Certificate. The OID Regulations also would permit a certificateholder to elect
to accrue de minimis original issue discount into income currently based on a
constant yield method. See "Taxation of Owners of REMIC Regular Certificates --
Market Discount" for a description of this election under the OID Regulations.

         If original issue discount on a REMIC Regular Certificate is in excess
of a de minimis amount, the holder of the certificate must include in ordinary
gross income the sum of the "daily portions" of original issue discount for each
day during its taxable year on which it held the REMIC Regular Certificate,
including the purchase date but excluding the disposition date. In the case of
an original holder of a REMIC Regular Certificate, the daily portions of
original issue discount will be determined as follows.

         As to each "accrual period," that is, each period that ends on a date
that corresponds to the day prior to each distribution date and begins on the
first day following the immediately preceding accrual period (or in the case of
the first such period, begins on the Closing Date), a calculation will be made
of the portion of the original issue discount that accrued during the accrual
period. The portion of original issue discount that accrues in any accrual
period will equal the excess, if any, of (1) the sum of (a) the present value,
as of the end of the accrual period, of all of the distributions remaining to be
made on the REMIC Regular Certificate, if any, in future periods and (b) the
distributions made on the REMIC Regular Certificate during the accrual period of
amounts included in the stated redemption price, over (2) the adjusted issue
price of the REMIC Regular Certificate at the beginning of the accrual period.
The present value of the remaining distributions referred to in the preceding
sentence will be calculated (1) assuming that distributions on the REMIC Regular
Certificate will be received in future periods based on the mortgage loans being
prepaid at a rate equal to the Prepayment Assumption, (2) using a discount rate
equal to the original yield to maturity of the certificate and (3) taking into
account events (including actual prepayments) that have occurred before the
close of the accrual period. For these purposes, the original yield to maturity
of the certificate will be calculated based on its issue price and assuming that
distributions on the certificate will be made in all accrual periods based on
the mortgage loans being prepaid at a rate equal to the Prepayment Assumption.
The adjusted issue price of a REMIC Regular Certificate at the beginning of any
accrual period will equal the issue price of the certificate, increased by the
aggregate amount of original issue discount that accrued with respect to the
certificate in prior accrual periods, and reduced by the amount of any
distributions made on the certificate in prior accrual periods of amounts
included in the stated redemption price. The original issue discount accruing
during any accrual period, computed as described above, will be allocated
ratably to each day during the accrual period to determine the daily portion of
original issue discount for that day.

         A subsequent purchaser of a REMIC Regular Certificate that purchases a
certificate that is treated as having been issued with original issue discount
at a cost (excluding any portion of the cost attributable to accrued qualified
stated interest) less than its remaining stated redemption price will also be
required to include in gross income the daily portions of any original issue
discount with respect to the certificate. However, each such daily portion will
be reduced, if the cost of the certificate is in excess of its "adjusted issue
price," in proportion to the ratio the excess bears to the aggregate original
issue discount remaining to be accrued on the REMIC



                                    - 113 -


Regular Certificate. The adjusted issue price of a REMIC Regular Certificate on
any given day equals the sum of (1) the adjusted issue price (or, in the case of
the first accrual period, the issue price) of the certificate at the beginning
of the accrual period which includes that day and (2) the daily portions of
original issue discount for all days during the accrual period prior to that
day.

         MARKET DISCOUNT. A certificateholder that purchases a REMIC Regular
Certificate at a market discount, that is, in the case of a REMIC Regular
Certificate issued without original issue discount, at a purchase price less
than its remaining stated principal amount, or in the case of a REMIC Regular
Certificate issued with original issue discount, at a purchase price less than
its adjusted issue price will recognize gain upon receipt of each distribution
representing stated redemption price. In particular, under Section 1276 of the
Code such a certificateholder generally will be required to allocate the portion
of each distribution representing stated redemption price first to accrued
market discount not previously included in income, and to recognize ordinary
income to that extent. A certificateholder may elect to include market discount
in income currently as it accrues rather than including it on a deferred basis
in accordance with the foregoing. If made, the election will apply to all market
discount bonds acquired by the certificateholder on or after the first day of
the first taxable year to which the election applies. In addition, the OID
Regulations permit a certificateholder to elect to accrue all interest, discount
(including de minimis market or original issue discount) in income as interest,
and to amortize premium, based on a constant yield method. If such an election
were made with respect to a REMIC Regular Certificate with market discount, the
certificateholder would be deemed to have made an election to include currently
market discount in income with respect to all other debt instruments having
market discount that the certificateholder acquires during the taxable year of
the election or thereafter, and possibly previously acquired instruments.
Similarly, a certificateholder that made this election for a certificate that is
acquired at a premium would be deemed to have made an election to amortize bond
premium with respect to all debt instruments having amortizable bond premium
that the certificateholder owns or acquires. See "Taxation of Owners of REMIC
Regular Certificates--Premium" below. Each of these elections to accrue
interest, discount and premium with respect to a certificate on a constant yield
method or as interest would be irrevocable, except with the approval of the IRS.

         However, market discount with respect to a REMIC Regular Certificate
will be considered to be de minimis for purposes of Section 1276 of the Code if
the market discount is less than 0.25% of the remaining stated redemption price
of the REMIC Regular Certificate multiplied by the number of complete years to
maturity remaining after the date of its purchase. In interpreting a similar
rule with respect to original issue discount on obligations payable in
installments, the OID Regulations refer to the weighted average maturity of
obligations, and it is likely that the same rule will be applied with respect to
market discount, presumably taking into account the Prepayment Assumption. If
market discount is treated as de minimis under this rule, it appears that the
actual discount would be treated in a manner similar to original issue discount
of a de minimis amount. See "Taxation of Owners of REMIC Regular
Certificates--Original Issue Discount" above. This treatment would result in
discount being included in income at a slower rate than discount would be
required to be included in income using the method described above.

         Section 1276(b)(3) of the Code specifically authorizes the Treasury
Department to issue regulations providing for the method for accruing market
discount on debt instruments, the



                                    - 114 -


principal of which is payable in more than one installment. Until regulations
are issued by the Treasury Department, the rules described in the Committee
Report apply. The Committee Report indicates that in each accrual period market
discount on REMIC Regular Certificates should accrue, at the certificateholder's
option: (1) on the basis of a constant yield method, (2) in the case of a REMIC
Regular Certificate issued without original issue discount, in an amount that
bears the same ratio to the total remaining market discount as the stated
interest paid in the accrual period bears to the total amount of stated interest
remaining to be paid on the REMIC Regular Certificate as of the beginning of the
accrual period, or (3) in the case of a REMIC Regular Certificate issued with
original issue discount, in an amount that bears the same ratio to the total
remaining market discount as the original issue discount accrued in the accrual
period bears to the total original issue discount remaining on the REMIC Regular
Certificate at the beginning of the accrual period. Moreover, the Prepayment
Assumption used in calculating the accrual of original issue discount is also
used in calculating the accrual of market discount. Because the regulations
referred to in this paragraph have not been issued, it is not possible to
predict what effect these regulations might have on the tax treatment of a REMIC
Regular Certificate purchased at a discount in the secondary market.

         To the extent that REMIC Regular Certificates provide for monthly or
other periodic distributions throughout their term, the effect of these rules
may be to require market discount to be includible in income at a rate that is
not significantly slower than the rate at which the discount would accrue if it
were original issue discount. Moreover, in any event a holder of a REMIC Regular
Certificate generally will be required to treat a portion of any gain on the
sale or exchange of the certificate as ordinary income to the extent of the
market discount accrued to the date of disposition under one of the foregoing
methods, less any accrued market discount previously reported as ordinary
income.

         Further, under Section 1277 of the Code a holder of a REMIC Regular
Certificate may be required to defer a portion of its interest deductions for
the taxable year attributable to any indebtedness incurred or continued to
purchase or carry a REMIC Regular Certificate purchased with market discount.
For these purposes, the de minimis rule referred to above applies. Any such
deferred interest expense would not exceed the market discount that accrues
during the taxable year and is, in general, allowed as a deduction not later
than the year in which the market discount is includible in income. If a holder
elects to include market discount in income currently as it accrues on all
market discount instruments acquired by the holder in that taxable year or
thereafter, the interest deferral rule described above will not apply.

         PREMIUM. A REMIC Regular Certificate purchased at a cost (excluding any
portion of the cost attributable to accrued qualified stated interest) greater
than its remaining stated redemption price will be considered to be purchased at
a premium. The holder of a REMIC Regular Certificate may elect under Section 171
of the Code to amortize the premium under the constant yield method over the
life of the certificate. If made, the election will apply to all debt
instruments having amortizable bond premium that the holder owns or subsequently
acquires. Amortizable premium will be treated as an offset to interest income on
the related debt instrument, rather than as a separate interest deduction. The
OID Regulations also permit certificateholders to elect to include all interest,
discount and premium in income based on a constant yield method, further
treating the certificateholder as having made the election to amortize premium
generally. See "Taxation of Owners of REMIC Regular Certificates--Market


                                    - 115 -


Discount" above. The Committee Report states that the same rules that apply to
accrual of market discount (which rules will require use of a Prepayment
Assumption in accruing market discount with respect to REMIC Regular
Certificates without regard to whether the certificates have original issue
discount) will also apply in amortizing bond premium under Section 171 of the
Code. The use of an assumption that there will be no prepayments may be
required.

         REALIZED LOSSES. Under Section 166 of the Code, both corporate holders
of the REMIC Regular Certificates and non-corporate holders of the REMIC Regular
Certificates that acquire the certificates in connection with a trade or
business should be allowed to deduct, as ordinary losses, any losses sustained
during a taxable year in which their certificates become wholly or partially
worthless as the result of one or more realized losses on the mortgage loans.
However, it appears that a non-corporate holder that does not acquire a REMIC
Regular Certificate in connection with a trade or business will not be entitled
to deduct a loss under Section 166 of the Code until the holder's certificate
becomes wholly worthless (i.e., until its outstanding principal balance has been
reduced to zero) and that the loss will be characterized as a short-term capital
loss.

         Each holder of a REMIC Regular Certificate will be required to accrue
interest and original issue discount with respect to the certificate, without
giving effect to any reductions in distributions attributable to defaults or
delinquencies on the mortgage loans or the certificate underlying the REMIC
Certificates, as the case may be, until it can be established that the reduction
ultimately will not be recoverable. As a result, the amount of taxable income
reported in any period by the holder of a REMIC Regular Certificate could exceed
the amount of economic income actually realized by that holder in the period.
Although the holder of a REMIC Regular Certificate eventually will recognize a
loss or reduction in income attributable to previously accrued and included
income that as the result of a realized loss ultimately will not be realized,
the law is unclear with respect to the timing and character of this loss or
reduction in income.

         TAXATION OF OWNERS OF REMIC RESIDUAL CERTIFICATES

         GENERAL. Although a REMIC is a separate entity for federal income tax
purposes, a REMIC generally is not subject to entity-level taxation, except with
regard to prohibited transactions and some other transactions. See "Prohibited
Transactions Tax and Other Taxes" below. Rather, the taxable income or net loss
of a REMIC is generally taken into account by the holder of the REMIC Residual
Certificates. Accordingly, the REMIC Residual Certificates will be subject to
tax rules that differ significantly from those that would apply if the REMIC
Residual Certificates were treated for federal income tax purposes as direct
ownership interests in the mortgage loans or as debt instruments issued by the
REMIC.

         A holder of a REMIC Residual Certificate generally will be required to
report its daily portion of the taxable income or, subject to the limitations
noted in this discussion, the net loss of the REMIC for each day during a
calendar quarter that the holder owned the REMIC Residual Certificate. For this
purpose, the taxable income or net loss of the REMIC will be allocated to each
day in the calendar quarter ratably using a "30 days per month/90 days per
quarter/360 days per year" convention unless otherwise disclosed in the related
prospectus supplement. The daily amounts so allocated will then be allocated
among the REMIC Residual Certificateholders in



                                    - 116 -


proportion to their respective ownership interests on that day. Any amount
included in the gross income or allowed as a loss of any REMIC Residual
Certificateholder by virtue of this paragraph will be treated as ordinary income
or loss. The taxable income of the REMIC will be determined under the rules
described below in "Taxable Income of the REMIC" and will be taxable to the
REMIC Residual Certificateholders without regard to the timing or amount of cash
distributions by the REMIC. Ordinary income derived from REMIC Residual
Certificates will be "portfolio income" for purposes of the taxation of
taxpayers subject to limitations under Section 469 of the Code on the
deductibility of "passive losses."

         A holder of a REMIC Residual Certificate that purchased the certificate
from a prior holder of that certificate also will be required to report on its
federal income tax return amounts representing its daily share of the taxable
income (or net loss) of the REMIC for each day that it holds the REMIC Residual
Certificate. Those daily amounts generally will equal the amounts of taxable
income or net loss determined as described above. The Committee Report indicates
that some modifications of the general rules may be made, by regulations,
legislation or otherwise to reduce (or increase) the income of a REMIC Residual
Certificateholder that purchased the REMIC Residual Certificate from a prior
holder of the certificate at a price greater than (or less than) the adjusted
basis (as defined below) the REMIC Residual Certificate would have had in the
hands of an original holder of the certificate. The REMIC Regulations, however,
do not provide for any such modifications.

         Any payments received by a holder of a REMIC Residual Certificate in
connection with the acquisition of the REMIC Residual Certificate will be taken
into account in determining the income of the holder for federal income tax
purposes. Although it appears likely that any of these payments would be
includible in income immediately upon its receipt, the IRS might assert that
these payments should be included in income over time according to an
amortization schedule or according to some other method. Because of the
uncertainty concerning the treatment of these payments, holders of REMIC
Residual Certificates are encouraged to consult their tax advisors concerning
the treatment of these payments for income tax purposes.

         The amount of income REMIC Residual Certificateholders will be required
to report (or the tax liability associated with the income) may exceed the
amount of cash distributions received from the REMIC for the corresponding
period. Consequently, REMIC Residual Certificateholders should have other
sources of funds sufficient to pay any federal income taxes due as a result of
their ownership of REMIC Residual Certificates or unrelated deductions against
which income may be offset, subject to the rules relating to "excess inclusions"
and "noneconomic" residual interests discussed below. The fact that the tax
liability associated with the income allocated to REMIC Residual
Certificateholders may exceed the cash distributions received by the REMIC
Residual Certificateholders for the corresponding period may significantly
adversely affect the REMIC Residual Certificateholders' after-tax rate of
return. This disparity between income and distributions may not be offset by
corresponding losses or reductions of income attributable to the REMIC Residual
Certificateholder until subsequent tax years and, then, may not be completely
offset due to changes in the Code, tax rates or character of the income or loss.

         On May 11, 2004, the Internal Revenue Service issued final regulations
relating to the federal income tax treatment of "inducement fees" received by
transferees of non-economic



                                    - 117 -


REMIC residual interests. The regulations provide tax accounting rules for the
inclusion of such fees in income over an appropriate period, and clarify that
inducement fees represent income from sources within the United States. These
rules apply to taxable years ending on or after May 11, 2004. On the same date,
the IRS issued administrative guidance addressing the procedures by which
transferees of such REMIC residual interests may obtain consent to change the
method of accounting for REMIC inducement fee income to one of the methods
provided in the regulations. Prospective purchasers of REMIC residual
certificates should consult with their tax advisors regarding the effect of
these regulations and the related administrative guidance.

         TAXABLE INCOME OF THE REMIC. The taxable income of the REMIC will equal
the income from the mortgage loans and other assets of the REMIC plus any
cancellation of indebtedness income due to the allocation of realized losses to
REMIC Regular Certificates, less the deductions allowed to the REMIC for
interest (including original issue discount and reduced by any premium on
issuance) on the REMIC Regular Certificates (and any other class of REMIC
Certificates constituting "regular interests" in the REMIC not offered by the
prospectus), amortization of any premium on the mortgage loans, bad debt losses
with respect to the mortgage loans and, except as described below, for
servicing, administrative and other expenses.

         For purposes of determining its taxable income, the REMIC will have an
initial aggregate basis in its assets equal to the sum of the issue prices of
all REMIC Certificates (or, if a class of REMIC Certificates is not sold
initially, their fair market values). The aggregate basis will be allocated
among the mortgage loans and the other assets of the REMIC in proportion to
their respective fair market values. The issue price of any offered REMIC
Certificates will be determined in the manner described above under "Taxation of
Owners of REMIC Regular Certificates -- Original Issue Discount." The issue
price of a REMIC Certificate received in exchange for an interest in the
mortgage loans or other property will equal the fair market value of the
interests in the mortgage loans or other property. Accordingly, if one or more
classes of REMIC Certificates are retained initially rather than sold, the REMIC
Administrator may be required to estimate the fair market value of the interests
in order to determine the basis of the REMIC in the mortgage loans and other
property held by the REMIC.

         Subject to possible application of the de minimis rules, the method of
accrual by the REMIC of original issue discount income and market discount
income with respect to mortgage loans that it holds will be equivalent to the
method for accruing original issue discount income for holders of REMIC Regular
Certificates (that is, under the constant yield method taking into account the
Prepayment Assumption). However, a REMIC that acquires loans at a market
discount must include the market discount in income currently, as it accrues, on
a constant yield basis. See "Taxation of Owners of REMIC Regular Certificates"
above, which describes a method for accruing discount income that is analogous
to that required to be used by a REMIC as to mortgage loans with market discount
that it holds.

         A mortgage loan will be deemed to have been acquired with discount (or
premium) to the extent that the REMIC's basis therein, determined as described
in the preceding paragraph, is less than (or greater than) its stated redemption
price. Any such discount will be includible in the income of the REMIC as it
accrues, in advance of receipt of the cash attributable to the income, under a
method similar to the method described above for accruing original issue
discount on the REMIC Regular Certificates. It is anticipated that each REMIC
will elect under Section 171 of



                                    - 118 -


the Code to amortize any premium on the mortgage loans. Premium on any mortgage
loan to which the election applies may be amortized under a constant yield
method, presumably taking into account a Prepayment Assumption. Further, such an
election would not apply to any mortgage loan originated on or before September
27, 1985. Instead, premium on such a mortgage loan should be allocated among the
principal payments thereon and be deductible by the REMIC as those payments
become due or upon the prepayment of the mortgage loan.

         A REMIC will be allowed deductions for interest (including original
issue discount) on the REMIC Regular Certificates (including any other class of
REMIC Certificates constituting "regular interests" in the REMIC not offered by
this prospectus) equal to the deductions that would be allowed if the REMIC
Regular Certificates (including any other class of REMIC Certificates
constituting "regular interests" in the REMIC not offered by this prospectus)
were indebtedness of the REMIC. Original issue discount will be considered to
accrue for this purpose as described above under "Taxation of Owners of REMIC
Regular certificates--Original Issue Discount," except that the de minimis rule
and the adjustments for subsequent holders of REMIC Regular Certificates
(including any other class of REMIC Certificates constituting "regular
interests" in the REMIC not offered by this prospectus) described therein will
not apply.

         If a class of REMIC Regular Certificates is issued with Issue Premium,
the net amount of interest deductions that are allowed the REMIC in each taxable
year with respect to the REMIC Regular Certificates of that class will be
reduced by an amount equal to the portion of the Issue Premium that is
considered to be amortized or repaid in that year. Although the matter is not
entirely clear, it is likely that Issue Premium would be amortized under a
constant yield method in a manner analogous to the method of accruing original
issue discount described above under "--Taxation of Owners of REMIC Regular
certificates--Original Issue Discount."

         As a general rule, the taxable income of a REMIC will be determined in
the same manner as if the REMIC were an individual having the calendar year as
its taxable year and using the accrual method of accounting. However, no item of
income, gain, loss or deduction allocable to a prohibited transaction will
betaken into account. See "--Prohibited Transactions Tax and Other Taxes" below.
Further, the limitation on miscellaneous itemized deductions imposed on
individuals by Section 67 of the Code (which allows these deductions only to the
extent they exceed in the aggregate two percent of the taxpayer's adjusted gross
income) will not be applied at the REMIC level so that the REMIC will be allowed
deductions for servicing, administrative and other non-interest expenses in
determining its taxable income. All such expenses will be allocated as a
separate item to the holders of REMIC Certificates, subject to the limitation of
Section 67 of the Code. See "Possible Pass-Through of Miscellaneous Itemized
Deductions" below. If the deductions allowed to the REMIC exceed its gross
income for a calendar quarter, the excess will be the net loss for the REMIC for
that calendar quarter.

         BASIS RULES, NET LOSSES AND DISTRIBUTIONS. The adjusted basis of a
REMIC Residual Certificate will be equal to the amount paid for the REMIC
Residual Certificate, increased by amounts included in the income of the REMIC
Residual Certificateholder and decreased (but not below zero) by distributions
made, and by net losses allocated, to the REMIC Residual Certificateholder.

                                    - 119 -


         A REMIC Residual Certificateholder is not allowed to take into account
any net loss for any calendar quarter to the extent the net loss exceeds the
REMIC Residual Certificateholder's adjusted basis in its REMIC Residual
Certificate as of the close of the calendar quarter (determined without regard
to the net loss). Any loss that is not currently deductible by reason of this
limitation may be carried forward indefinitely to future calendar quarters and,
subject tothe same limitation, may be used only to offset income from the REMIC
Residual Certificate. The ability of REMIC Residual Certificateholders to deduct
net losses may be subject to additional limitations under the Code, as to which
REMIC Residual Certificateholders are encouraged to consult their tax advisors.

         Any distribution on a REMIC Residual Certificate will be treated as a
non-taxable return of capital to the extent it does not exceed the holder's
adjusted basis in the REMIC Residual Certificate. To the extent a distribution
on a REMIC Residual Certificate exceeds the adjusted basis, it will be treated
as gain from the sale of the REMIC Residual Certificate. Holders of REMIC
Residual Certificates may be entitled to distributions early in the term of the
related REMIC under circumstances in which their bases in the REMIC Residual
Certificates will not be sufficiently large that the distributions will be
treated as nontaxable returns of capital. Their bases in the REMIC Residual
Certificates will initially equal the amount paid for the REMIC Residual
Certificates and will be increased by their allocable shares of taxable income
of the REMIC. However, these bases increases may not occur until the end of the
calendar quarter, or perhaps the end of the calendar year, with respect to which
the REMIC taxable income is allocated to the REMIC Residual Certificateholders.
To the extent the REMIC Residual Certificateholders' initial bases are less than
the distributions to the REMIC Residual Certificateholders, and increases in
initial bases either occur after the distributions or (together with their
initial bases) are less than the amount of the distributions, gain will be
recognized to the REMIC Residual Certificateholders on these distributions and
will be treated as gain from the sale of their REMIC Residual Certificates.

         The effect of these rules is that a REMIC Residual Certificateholder
may not amortize its basis in a REMIC Residual Certificate, but may only recover
its basis through distributions, through the deduction of any net losses of the
REMIC or upon the sale of its REMIC Residual Certificate. See "--Sales of REMIC
Certificates" below. For a discussion of possible modifications of these rules
that may require adjustments to income of a holder of a REMIC Residual
Certificate other than an original holder in order to reflect any difference
between the cost of the REMIC Residual Certificate to the REMIC Residual
Certificateholder and the adjusted basis the REMIC Residual Certificate would
have in the hands of an original holder, see "--Taxation of Owners of REMIC
Residual Certificates--General" above.

         EXCESS INCLUSIONS. Any "excess inclusions" with respect to a REMIC
Residual Certificate will be subject to federal income tax in all events. In
general, the "excess inclusions" with respect to a REMIC Residual Certificate
for any calendar quarter will be the excess, if any, of (1) the daily portions
of REMIC taxable income allocable to the REMIC Residual Certificate over (2) the
sum of the "daily accruals" (as defined below) for each day during the quarter
that the REMIC Residual Certificate was held by the REMIC Residual
Certificateholder. The daily accruals of a REMIC Residual Certificateholder will
be determined by allocating to each day during a calendar quarter its ratable
portion of the product of the "adjusted issue price" of the REMIC Residual
Certificate at the beginning of the calendar quarter and 120% of the "long-term


                                    - 120 -


Federal rate" in effect on the Closing Date. For this purpose, the adjusted
issue price of a REMIC Residual Certificate as of the beginning of any calendar
quarter will be equal to the issue price of the REMIC Residual Certificate,
increased by the sum of the daily accruals for all prior quarters and decreased
(but not below zero) by any distributions made with respect to the REMIC
Residual Certificate before the beginning of that quarter. The issue price of a
REMIC Residual Certificate is the initial offering price to the public
(excluding bond houses and brokers) at which a substantial amount of the REMIC
Residual Certificates were sold. The "long-term Federal rate" is an average of
current yields on Treasury securities with a remaining term of greater than nine
years, computed and published monthly by the IRS. Although it has not done so,
the Treasury has authority to issue regulations that would treat the entire
amount of income accruing on a REMIC Residual Certificate as an excess inclusion
if the REMIC Residual Certificates are considered to have "significant value."

         For REMIC Residual Certificateholders, an excess inclusion (1) will not
be permitted to be offset by deductions, losses or loss carryovers from other
activities, (2) will be treated as "unrelated business taxable income" to an
otherwise tax-exempt organization and (3) will not be eligible for any rate
reduction or exemption under any applicable tax treaty with respect to the 30%
United States withholding tax imposed on distributions to REMIC Residual
Certificateholders that are foreign investors. See, however, "Foreign investors
in REMIC Certificates," below.

         Furthermore, for purposes of the alternative minimum tax, excess
inclusions will not be permitted to be offset by the alternative tax net
operating loss deduction and alternative minimum taxable income may not be less
than the taxpayer's excess inclusions. The latter rule has the effect of
preventing nonrefundable tax credits from reducing the taxpayer's income tax to
an amount lower than the tentative minimum tax on excess inclusions.

         In the case of any REMIC Residual Certificates held by a real estate
investment trust, the aggregate excess inclusions with respect to the REMIC
Residual Certificates, reduced (but not below zero) by the real estate
investment trust taxable income (within the meaning of Section 857(b)(2) of the
Code, excluding any net capital gain), will be allocated among the shareholders
of the trust in proportion to the dividends received by the shareholders from
the trust, and any amount so allocated will be treated as an excess inclusion
with respect to a REMIC Residual Certificate as if held directly by the
shareholder. Treasury regulations yet to be issued could apply a similar rule to
regulated investment companies, common trust funds and cooperatives; the REMIC
Regulations currently do not address this subject.

         NONECONOMIC REMIC RESIDUAL CERTIFICATES. Under the REMIC Regulations,
transfers of "non-economic" REMIC Residual Certificates will be disregarded for
all federal income tax purposes if "a significant purpose of the transfer was to
enable the transferor to impede the assessment or collection of tax." If the
transfer is disregarded, the purported transferor will continue to remain liable
for any taxes due with respect to the income on the "non-economic" REMIC
Residual Certificate. The REMIC Regulations provide that a REMIC Residual
Certificate is non-economic unless, based on the Prepayment Assumption and on
any required or permitted clean up calls, or required liquidation provided for
in the REMIC's organizational documents, (1) the present value of the expected
future distributions (discounted using the "applicable Federal rate" for
obligations whose term ends on the close of the last quarter



                                    - 121 -


in which excess inclusions are expected to accrue with respect to the REMIC
Residual Certificate, which rate is computed and published monthly by the IRS)
on the REMIC Residual Certificate equals at least the present value of the
expected tax on the anticipated excess inclusions, and (2) the transferor
reasonably expects that the transferee will receive distributions with respect
to the REMIC Residual Certificate at or after the time the taxes accrue on the
anticipated excess inclusions in an amount sufficient to satisfy the accrued
taxes. Accordingly, all transfers of REMIC Residual Certificates that may
constitute non-economic residual interests will be subject to restrictions under
the terms of the related pooling and servicing agreement that are intended to
reduce the possibility of any such transfer being disregarded. These
restrictions will require each party to a transfer to provide an affidavit that
no purpose of the transfer is to impede the assessment or collection of tax,
including representations as to the financial condition of the prospective
transferee, as to which the transferor is also required to make a reasonable
investigation to determine the transferee's historic payment of its debts and
ability to continue to pay its debts as they come due in the future. The IRS has
issued proposed changes to REMIC Regulations that would add to the conditions
necessary to assure that a transfer of a non-economic residual interest would be
respected. The proposed additional condition would require that the amount
received by the transferee be no less on a present value basis than the present
value of the net tax detriment attributable to holding a residual interest
reduced by the present value of the projected payments to be received on the
residual interest. In Revenue Procedure 2001-12, pending finalization of the new
regulations, the IRS has expanded the "safe harbor" for transfers of
non-economic residual interests to include certain transfers to domestic taxable
corporations with large amounts of gross and net assets where agreement is made
that all future transfers will be to taxable domestic corporations in
transactions that qualify for one of the "safe harbor" provisions. Eligibility
for this safe harbor requires, among other things, that the facts and
circumstances known to the transferor at the time of transfer not indicate to a
reasonable person that the taxes with respect to the residual interest will not
be paid, with an unreasonably low cost for the transfer specifically mentioned
as negating eligibility. The regulations generally apply to transfers of
residual interests occurring on or after February 4, 2000. Prior to purchasing a
REMIC Residual Certificate, prospective purchasers are encouraged to consider
the possibility that a purported transfer of the REMIC Residual Certificate by
such a purchaser to another purchaser at some future date may be disregarded in
accordance with the above-described rules which would result in the retention of
tax liability by the purchaser.

         The related prospectus supplement will disclose whether offered REMIC
Residual Certificates may be considered "noneconomic" residual interests under
the REMIC Regulations; provided, however, that any disclosure that a REMIC
Residual Certificate will not be considered "noneconomic" will be based upon
assumptions, and the depositor will make no representation that a REMIC Residual
Certificate will not be considered "non-economic" for purposes of the
above-described rules. See "--Foreign Investors in REMIC Certificates--REMIC
Residual Certificates" below for additional restrictions applicable to transfers
of REMIC Residual Certificates to foreign persons.

         On May 11, 2004, the IRS issued final regulations relating to the
federal income tax treatment of "inducement fees" received by transferees of
noneconomic REMIC residual interests. The regulations provide tax accounting
rules for the inclusion of such fees in income over an appropriate period, and
clarify that inducement fees represent income from sources within the United
States. These rules apply to taxable years ending on or after May 11, 2004. On


                                    - 122 -


the same date, the IRS issued administrative guidance addressing the procedures
by which transferees of such REMIC residual interests may obtain consent to
change the method of accounting for REMIC inducement fee income to one of the
methods provided in the regulations. Prospective purchasers of REMIC Residual
Certificates are encouraged to consult with their tax advisors regarding the
effect of these regulations and the related administrative guidance.

         MARK-TO-MARKET RULES. In general, all securities owned by a dealer,
except to the extent that the dealer has specifically identified a security as
held for investment, must be marked to market in accordance with the applicable
Code provision and the related regulations. However, the IRS has issued
regulations which provide that for purposes of this mark-to-market requirement,
a REMIC Residual Certificate acquired after January 4, 1995 is not treated as a
security and thus may not be marked to market. Prospective purchasers of a REMIC
Residual Certificate should consult their tax advisors regarding the possible
application of the mark-to-market requirement to REMIC Residual Certificates.

         POSSIBLE PASS-THROUGH OF MISCELLANEOUS ITEMIZED DEDUCTIONS. Fees and
expenses of a REMIC generally will be allocated to the holders of the related
REMIC Residual Certificates. The applicable Treasury regulations indicate,
however, that in the case of a REMIC that is similar to a single class grantor
trust, all or a portion of these fees and expenses should be allocated to the
holders of the related REMIC Regular Certificates. Except as stated in the
related prospectus supplement, these fees and expenses will be allocated to
holders of the related REMIC Residual Certificates in their entirety and not to
the holders of the related REMIC Regular Certificates.

         With respect to REMIC Residual Certificates or REMIC Regular
Certificates the holders of which receive an allocation of fees and expenses in
accordance with the preceding discussion, if any holder thereof is an
individual, estate or trust, or a "pass-through entity" beneficially owned by
one or more individuals, estates or trusts, (1) an amount equal to the
individual's, estate's or trust's share of the fees and expenses will be added
to the gross income of the holder and (2) the individual's, estate's or trust's
share of the fees and expenses will be treated as a miscellaneous itemized
deduction allowable subject to the limitation of Section 67 of the Code, which
permits these deductions only to the extent they exceed in the aggregate two
percent of taxpayer's adjusted gross income. In addition, Section 68 of the Code
provides that the amount of itemized deductions otherwise allowable for an
individual whose adjusted gross income exceeds a specified amount will be. The
amount of additional taxable income reportable by REMIC Certificateholders that
are subject to the limitations of either Section 67 or Section 68 of the Code
may be substantial. Furthermore, in determining the alternative minimum taxable
income of such a holder of a REMIC Certificate that is an individual, estate or
trust, or a "pass-through entity" beneficially owned by one or more individuals,
estates or trusts, no deduction will be allowed for the holder's allocable
portion of servicing fees and other miscellaneous itemized deductions of the
REMIC, even though an amount equal to the amount of the fees and other
deductions will be included in the holder's gross income. Accordingly, these
REMIC Certificates may not be appropriate investments for individuals, estates,
or trusts, or pass-through entities beneficially owned by one or more
individuals, estates or trusts. Prospective investors are encouraged to consult
with their tax advisors prior to making an investment in the certificates.

                                    - 123 -


         SALES OF REMIC CERTIFICATES. If a REMIC Certificate is sold, the
selling Certificateholder will recognize gain or loss equal to the difference
between the amount realized on the sale and its adjusted basis in the REMIC
Certificate. The adjusted basis of a REMIC Regular Certificate generally will
equal the cost of the REMIC Regular Certificate to the certificateholder,
increased by income reported by the certificateholder with respect to the REMIC
Regular Certificate (including original issue discount and market discount
income) and reduced (but not below zero) by distributions on the REMIC Regular
Certificate received by the certificateholder and by any amortized premium. The
adjusted basis of a REMIC Residual Certificate will be determined as described
under "--Taxation of Owners of REMIC Residual Certificates--Basis Rules, Net
Losses and Distributions." Except as provided in the following four paragraphs,
any such gain or loss will be capital gain or loss, provided the REMIC
Certificate is held as a capital asset (generally, property held for investment)
within the meaning of Section 1221 of the Code.

         Gain from the sale of a REMIC Regular Certificate that might otherwise
be capital gain will be treated as ordinary income to the extent the gain does
not exceed the excess, if any, of (1) the amount that would have been includible
in the seller's income with respect to the REMIC Regular Certificate assuming
that income had accrued thereon at a rate equal to 110% of the "applicable
Federal rate" (generally, a rate based on an average of current yields on
Treasury securities having a maturity comparable to that of the certificate
based on the application of the Prepayment Assumption to the certificate, which
rate is computed and published monthly by the IRS), determined as of the date of
purchase of the REMIC Regular Certificate, over (2) the amount of ordinary
income actually includible in the seller's income prior to the sale. In
addition, gain recognized on the sale of a REMIC Regular Certificate by a seller
who purchased the REMIC Regular Certificate at a market discount will be taxable
as ordinary income in an amount not exceeding the portion of the discount that
accrued during the period the REMIC Certificate was held by the holder, reduced
by any market discount included in income under the rules described above under
"Taxation of Owners of REMIC Regular Certificates--Market Discount" and
"--Premium."

         REMIC Certificates will be "evidences of indebtedness" within the
meaning of Section 582(c)(1) of the Code, so that gain or loss recognized from
the sale of a REMIC Certificate by a bank or thrift institution to which this
section applies will be ordinary income or loss.

         A portion of any gain from the sale of a REMIC Regular Certificate that
might otherwise be capital gain may be treated as ordinary income to the extent
that the certificate is held as part of a "conversion transaction" within the
meaning of Section 1258 of the Code. A conversion transaction generally is one
in which the taxpayer has taken two or more positions in the same or similar
property that reduce or eliminate market risk, if substantially all of the
taxpayer's return is attributable to the time value of the taxpayer's net
investment in the transaction. The amount of gain so realized in a conversion
transaction that is recharacterized as ordinary income generally will not exceed
the amount of interest that would have accrued on the taxpayer's net investment
at 120% of the appropriate "applicable Federal rate" (which rate is computed and
published monthly by the IRS) at the time the taxpayer enters into the
conversion transaction, subject to appropriate reduction for prior inclusion of
interest and other ordinary income items from the transaction.

                                    - 124 -


         Finally, a taxpayer may elect to have net capital gain taxed at
ordinary income rates rather than capital gains rates in order to include the
net capital gain in total net investment income for the taxable year, for
purposes of the rule that limits the deduction of interest on indebtedness
incurred to purchase or carry property held for investment to a taxpayer's net
investment income.

         Except as may be provided in Treasury regulations yet to be issued, if
the seller of a REMIC Residual Certificate reacquires the REMIC Residual
Certificate, or acquires any other residual interest in a REMIC or any similar
interest in a "taxable mortgage pool" (as defined in Section 7701(i) of the
Code) during the period beginning six months before, and ending six months
after, the date of the sale, such sale will be subject to the "wash sale" rules
of Section 1091 of the Code. In that event, any loss realized by the REMIC
Residual Certificateholder on the sale will not be deductible, but instead will
be added to the REMIC Residual Certificateholder's adjusted basis in the
newly-acquired asset.

         PROHIBITED TRANSACTIONS AND OTHER POSSIBLE REMIC TAXES. In the event a
REMIC engages in a prohibited transaction, the Code imposes a 100% tax on the
income derived by the REMIC from the prohibited transaction. In general, subject
to specified exceptions, a prohibited transaction means the disposition of a
mortgage loan, the receipt of income from a source other than a mortgage loan or
other permitted investments, the receipt of compensation for services, or gain
from the disposition of an asset purchased with the payments on the mortgage
loans for temporary investment pending distribution on the REMIC Certificates.
It is not anticipated that any REMIC will engage in any prohibited transactions
in which it would recognize a material amount of net income.

         In addition, a contribution to a REMIC made after the day on which the
REMIC issues all of its interests could result in the imposition on the REMIC of
a tax equal to 100% of the value of the contributed property. Each pooling and
servicing agreement will include provisions designed to prevent the acceptance
of any contributions that would be subject to this tax.

         REMICs also are subject to federal income tax at the highest corporate
rate on "net income from foreclosure property," determined by reference to the
rules applicable to real estate investment trusts. "Net income from foreclosure
property" generally means gain from the sale of a foreclosure property that is
inventory property and gross income from foreclosure property other than
qualifying rents and other qualifying income for a real estate investment trust.
It is not anticipated that any REMIC will recognize "net income from foreclosure
property" subject to federal income tax.

         To the extent permitted by then applicable laws, any tax resulting from
a prohibited transaction, tax resulting from a contribution made after the
Closing Date, tax on "net income from foreclosure property" or state or local
income or franchise tax that may be imposed on the REMIC will be borne by the
related master servicer or trustee in either case out of its own funds, provided
that the master servicer or the trustee, as the case may be, has sufficient
assets to do so, and provided further that the tax arises out of a breach of the
master servicer's or the trustee's obligations, as the case may be, under the
related pooling and servicing agreement and in respect of compliance with
applicable laws and regulations. Any such tax not borne by the master



                                    - 125 -


servicer or the trustee will be charged against the related trust fund resulting
in a reduction in amounts payable to holders of the related REMIC Certificates.

         TAX AND RESTRICTIONS ON TRANSFERS OF REMIC RESIDUAL CERTIFICATES TO
CERTAIN ORGANIZATIONS. If a REMIC Residual Certificate is transferred to a
"disqualified organization" (as defined below), a tax would be imposed in an
amount (determined under the REMIC Regulations) equal to the product of (1) the
present value (discounted using the "applicable Federal rate" for obligations
whose term ends on the close of the last quarter in which excess inclusions are
expected to accrue with respect to the REMIC Residual Certificate, which rate is
computed and published monthly by the IRS) of the total anticipated excess
inclusions with respect to the REMIC Residual Certificate for periods after the
transfer and (2) the highest marginal federal income tax rate applicable to
corporations. The anticipated excess inclusions must be determined as of the
date that the REMIC Residual Certificate is transferred and must be based on
events that have occurred up to the time of the transfer, the Prepayment
Assumption and any required or permitted clean up calls or required liquidation
provided for in the REMIC's organizational documents. Such a tax generally would
be imposed on the transferor of the REMIC Residual Certificate, except that
where the transfer is through an agent for a disqualified organization, the tax
would instead be imposed on the agent. However, a transferor of a REMIC Residual
Certificate would in no event be liable for the tax with respect to a transfer
if the transferee furnishes to the transferor an affidavit that the transferee
is not a disqualified organization and, as of the time of the transfer, the
transferor does not have actual knowledge that the affidavit is false. Moreover,
an entity will not qualify as a REMIC unless there are reasonable arrangements
designed to ensure that (1) residual interests in the entity are not held by
disqualified organizations and (2) information necessary for the application of
the tax described herein will be made available. Restrictions on the transfer of
REMIC Residual Certificates and other provisions that are intended to meet this
requirement will be included in the pooling and servicing agreement, and will be
discussed more fully in any prospectus supplement relating to the offering of
any REMIC Residual Certificate.

         In addition, if a "pass-through entity" (as defined below) includes in
income excess inclusions with respect to a REMIC Residual Certificate, and a
disqualified organization is the record holder of an interest in the entity,
then a tax will be imposed on the entity equal to the product of (1) the amount
of excess inclusions on the REMIC Residual Certificate that are allocable to the
interest in the pass-through entity held by the disqualified organization and
(2) the highest marginal federal income tax rate imposed on corporations. A
pass-through entity will not be subject to this tax for any period, however, if
each record holder of an interest in the pass-through entity furnishes to the
pass-through entity (1) the holder's social security number and a statement
under penalties of perjury that the social security number is that of the
recordholder or (2) a statement under penalties of perjury that the record
holder is not a disqualified organization. For taxable years beginning after
December 31,1997, notwithstanding the preceding two sentences, in the case of a
REMIC Residual Certificate held by an "electing large partnership," all
interests in the partnership shall be treated as held by disqualified
organizations (without regard to whether the record holders of the partnership
furnish statements described in the preceding sentence) and the amount that is
subject to tax under the second preceding sentence is excluded from the gross
income of the partnership allocated to the partners (in lieu of allocating to
the partners a deduction for the tax paid by the partnership).

                                    - 126 -



         For these purposes, a "disqualified organization" means:

         o        the United States, any State or political subdivision thereof,
                  any foreign government, any international organization, or any
                  agency or instrumentality of the foregoing (but would not
                  include instrumentalities described in Section 168(h)(2)(D) of
                  the Code or Freddie Mac),

         o        any organization (other than a cooperative described in
                  Section 521 of the Code) that is exempt from federal income
                  tax, unless it is subject to the tax imposed by Section 511 of
                  the Code,

         o        any organization described in Section 1381(a)(2)(C) of the
                  Code, or

         o        an electing large partnership within the meaning of Section
                  775 of the Code.

For these purposes, a "pass-through entity" means any regulated investment
company, real estate investment trust, trust, partnership or certain other
entities described in Section 860E(e)(6) of the Code. In addition, a person
holding an interest in a pass-through entity as a nominee for another person
will, with respect to the interest, be treated as a pass-through entity.

         TERMINATION. A REMIC will terminate immediately after the distribution
date following receipt by the REMIC of the final payment in respect of the
mortgage loans or upon a sale of the REMIC's assets following the adoption by
the REMIC of a plan of complete liquidation. The last distribution on a REMIC
Regular Certificate will be treated as a payment in retirement of a debt
instrument. In the case of a REMIC Residual Certificate, if the last
distribution on the REMIC Residual Certificate is less than the REMIC Residual
Certificateholder's adjusted basis in the certificate, the REMIC Residual
Certificateholder should (but may not) be treated as realizing a loss equal to
the amount of the difference, and the loss may be treated as a capital loss.

         REPORTING AND OTHER ADMINISTRATIVE MATTERS. Solely for purposes of the
administrative provisions of the Code, the REMIC will be treated as a
partnership and REMIC Residual Certificateholders will be treated as partners.
The REMIC Administrator (or other party described in the related prospectus
supplement) will file REMIC federal income tax returns on behalf of the related
REMIC, and under the terms of the related Agreement, will either (1) be
irrevocably appointed by the holders of the largest percentage interest in the
related REMIC Residual Certificates as their agent to perform all of the duties
of the "tax matters person" with respect to the REMIC in all respects or (2)
will be designated as and will act as the "tax matters person" with respect to
the related REMIC in all respects and will hold at least a nominal amount of
REMIC Residual Certificates.

         The REMIC Administrator, as the tax matters person or as agent for the
tax matters person, subject to notice requirements and various restrictions and
limitations, generally will have the authority to act on behalf of the REMIC and
the REMIC Residual Certificateholders in connection with the administrative and
judicial review of items of income, deduction, gain or loss of the REMIC, as
well as the REMIC's classification. REMIC Residual Certificateholders generally
will be required to report these REMIC items consistently with their treatment
on the REMIC's tax return and may in some circumstances be bound by a settlement
agreement



                                    - 127 -


between the REMIC Administrator, as either tax matters person or as agent for
the tax matters person, and the IRS concerning any such REMIC item. Adjustments
made to the REMIC tax return may require a REMIC Residual Certificateholder to
make corresponding adjustments on its return, and an audit of the REMIC's tax
return, or the adjustments resulting from such an audit, could result in an
audit of a REMIC Residual Certificateholder's return. Any person that holds a
REMIC Residual Certificate as a nominee for another person may be required to
furnish the REMIC, in a manner to be provided in Treasury regulations, with the
name and address of the person and other information.

         Reporting of interest income, including any original issue discount,
with respect to REMIC Regular Certificates is required annually, and may be
required more frequently under Treasury regulations. These information reports
generally are required to be sent to individual holders of REMIC Regular
Interests and the IRS; holders of REMIC Regular Certificates that are
corporations, trusts, securities dealers and some other non-individuals will be
provided interest and original issue discount income information and the
information set forth in the following paragraph upon request in accordance with
the requirements of the applicable regulations. The information must be provided
by the later of 30 days after the end of the quarter for which the information
was requested, or two weeks after the receipt of the request. The REMIC must
also comply with rules requiring a REMIC Regular Certificate issued with
original issue discount to disclose on its face the amount of original issue
discount and the issue date, and requiring the information to be reported to the
IRS. Reporting with respect to the REMIC Residual Certificates, including
income, excess inclusions, investment expenses and relevant information
regarding qualification of the REMIC's assets will be made as required under the
Treasury regulations, generally on a quarterly basis.

         As applicable, the REMIC Regular Certificate information reports will
include a statement of the adjusted issue price of the REMIC Regular Certificate
at the beginning of each accrual period. In addition, the reports will include
information required by regulations with respect to computing the accrual of any
market discount. Because exact computation of the accrual of market discount on
a constant yield method would require information relating to the holder's
purchase price that the REMIC may not have, Treasury regulations only require
that information pertaining to the appropriate proportionate method of accruing
market discount be provided. See "--Taxation of Owners of REMIC Regular
Certificates--Market Discount."

         The responsibility for complying with the foregoing reporting rules
will be borne by the REMIC Administrator or other party designated in the
related prospectus supplement.

         BACKUP WITHHOLDING WITH RESPECT TO REMIC CERTIFICATES. Payments of
interest and principal, as well as payments of proceeds from the sale of REMIC
Certificates, may be subject to the "backup withholding tax" under Section 3406
of the Code if recipients of the payments fail to furnish to the payor certain
information, including their taxpayer identification numbers, or otherwise fail
to establish an exemption from the backup withholding tax. Any amounts deducted
and withheld from a distribution to a recipient would be allowed as a credit
against the recipient's federal income tax. Furthermore, penalties may be
imposed by the IRS on a recipient of payments that is required to supply
information but that does not do so in the proper manner.

                                    - 128 -



         FOREIGN INVESTORS IN REMIC CERTIFICATES. A REMIC Regular
Certificateholder that is not a United States Person and is not subject to
federal income tax as a result of any direct or indirect connection to the
United States in addition to its ownership of a REMIC Regular Certificate will
not be subject to United States federal income or withholding tax in respect of
a distribution on a REMIC Regular Certificate, provided that the holder complies
to the extent necessary with identification requirements, including delivery of
a statement, signed by the certificateholder under penalties of perjury,
certifying that the certificateholder is not a United States person and
providing the name and address of the certificateholder. This statement is
generally made on IRS Form W-8BEN and must be updated whenever required
information has changed or within 3 calendar years after the statement is first
delivered. It is possible that the IRS may assert that the foregoing tax
exemption should not apply with respect to a REMIC Regular Certificate held by a
REMIC Residual Certificateholder that owns directly or indirectly a 10% or
greater interest in the REMIC Residual Certificates. If the holder does not
qualify for exemption, distributions of interest, including distributions in
respect of accrued original issue discount, to the holder may be subject to a
tax rate of 30%, subject to reduction under any applicable tax treaty.

         Special rules apply to partnerships, estates and trusts, and in certain
circumstances certifications as to foreign status and other matters may be
required to be provided by partners and beneficiaries thereof.

         In addition, in certain circumstances the foregoing rules will not
apply to exempt a United States shareholder of a controlled foreign corporation
from taxation on the United States shareholder's allocable portion of the
interest income received by the controlled foreign corporation.

         Further, it appears that a REMIC Regular Certificate would not be
included in the estate of a non- resident alien individual and would not be
subject to United States estate taxes. However, certificateholders who are
non-resident alien individuals are encouraged consult their tax advisors
concerning this question.

         Except as stated in the related prospectus supplement, transfers of
REMIC Residual Certificates to investors that are not United States persons will
be prohibited under the related pooling and servicing agreement.

         NEW WITHHOLDING REGULATIONS

         The Treasury Department has issued new final regulations which provide
in greater detail the procedures for complying with, or obtaining exemptions
under, the withholding, backup withholding and information reporting rules
described above. Prospective investors are urged to consult their tax advisors
regarding the procedures for obtaining an exemption from withholding under these
regulations.

NOTES

         On or prior to the date of the related prospectus supplement with
respect to the proposed issuance of each series of notes, Thacher Proffitt &
Wood LLP, counsel to the depositor, will deliver its opinion to the effect that,
assuming compliance with all provisions of the indenture,



                                    - 129 -


owner trust agreement and other related documents, for federal income tax
purposes (1) the notes will be treated as indebtedness and (2) the Issuing
Entity, as created pursuant to the terms and conditions of the owner trust
agreement, will not be characterized as an association (or publicly traded
partnership) taxable as a corporation or as a taxable mortgage pool. For
purposes of this tax discussion, references to a "noteholder" or a "holder" are
to the beneficial owner of a note.

         STATUS AS REAL PROPERTY LOANS

         Notes held by a domestic building and loan association will not
constitute "loans... secured by an interest in real property" within the meaning
of Code section 7701(a)(19)(C)(v); and (2) notes held by a real estate
investment trust will not constitute "real estate assets" within the meaning of
Code section 856(c)(4)(A) and interest on notes will not be considered "interest
on obligations secured by mortgages on real property" within the meaning of Code
section 856(c)(3)(B).

         TAXATION OF NOTEHOLDERS

         Notes generally will be subject to the same rules of taxation as REMIC
Regular Certificates issued by a REMIC, as described above, except that (1)
income reportable on the notes is not required to be reported under the accrual
method unless the holder otherwise uses the accrual method and (2) the special
rule treating a portion of the gain on sale or exchange of a REMIC Regular
Certificate as ordinary income is inapplicable to the notes. See
"REMICs--Taxation of Owners of REMIC Regular Certificates" and "--Sales of REMIC
Certificates."

GRANTOR TRUST FUNDS

         CLASSIFICATION OF GRANTOR TRUST FUNDS. On or prior to the date of the
related prospectus supplement with respect to the proposed issuance of each
series of Grantor Trust Certificates, Thacher Proffitt & Wood LLP, counsel to
the depositor, will deliver its opinion generally to the effect that, assuming
compliance with all provisions of the related pooling and servicing agreement,
the related Grantor Trust Fund will be classified as a grantor trust under
subpart E, part I of subchapter J of Chapter 1 of the Code and not as a
partnership or an association taxable as a corporation.

         CHARACTERIZATION OF INVESTMENTS IN GRANTOR TRUST CERTIFICATES.

         GRANTOR TRUST FRACTIONAL INTEREST CERTIFICATES. In the case of Grantor
Trust Fractional Interest Certificates, except as disclosed in the related
prospectus supplement, counsel to the depositor will deliver an opinion that, in
general, Grantor Trust Fractional Interest Certificates will represent interests
in (1) "loans . . . secured by an interest in real property" within the meaning
of Section 7701(a)(19)(C)(v) of the Code; (2) "obligation[s] (including any
participation or Certificate of beneficial ownership therein) which [are]
principally secured by an interest in real property" within the meaning of
Section 860G(a)(3) of the Code; and (3) "real estate assets" within the meaning
of Section 856(c)(4)(A) of the Code. In addition, counsel to the depositor will
deliver an opinion that interest on Grantor Trust Fractional Interest
Certificates will to the same extent be considered "interest on obligations
secured by mortgages on real property or on interests in real property" within
the meaning of Section 856(c)(3)(B) of the Code.

                                    - 130 -



         GRANTOR TRUST STRIP CERTIFICATES. Even if Grantor Trust Strip
Certificates evidence an interest in a Grantor Trust Fund consisting of mortgage
loans that are "loans . . . secured by an interest in real property" within the
meaning of Section 7701(a)(19)(C)(v) of the Code, and "real estate assets"
within the meaning of Section 856(c)(4)(A) of the Code, and the interest on
which is "interest on obligations secured by mortgages on real property" within
the meaning of Section 856(c)(3)(B) of the Code, it is unclear whether the
Grantor Trust Strip Certificates, and the income therefrom, will be so
characterized. However, the policies underlying these sections (namely, to
encourage or require investments in mortgage loans by thrift institutions and
real estate investment trusts) may suggest that this characterization is
appropriate. Counsel to the depositor will not deliver any opinion on these
questions. Prospective purchasers to which the characterization of an investment
in Grantor Trust Strip Certificates is material are encouraged to consult their
tax advisors regarding whether the Grantor Trust Strip Certificates, and the
income therefrom, will be so characterized.

         The Grantor Trust Strip Certificates will be "obligation[s] (including
any participation or Certificate of beneficial ownership therein) which . .
..[are] principally secured by an interest in real property" within the meaning
of Section 860G(a)(3)(A) of the Code.

         TAXATION OF OWNERS OF GRANTOR TRUST FRACTIONAL INTEREST CERTIFICATES.
Holders of a particular series of Grantor Trust Fractional Interest Certificates
generally will be required to report on their federal income tax returns their
shares of the entire income from the mortgage loans (including amounts used to
pay reasonable servicing fees and other expenses) and will be entitled to deduct
their shares of any such reasonable servicing fees and other expenses. Because
of stripped interests, market or original issue discount, or premium, the amount
includible in income on account of a Grantor Trust Fractional Interest
Certificate may differ significantly from the amount distributable thereon
representing interest on the mortgage loans. Under Section 67 of the Code, an
individual, estate or trust holding a Grantor Trust Fractional Interest
Certificate directly or through some pass-through entities will be allowed a
deduction for the reasonable servicing fees and expenses only to the extent that
the aggregate of the holder's miscellaneous itemized deductions exceeds two
percent of the holder's adjusted gross income. In addition, Section 68 of the
Code provides that the amount of itemized deductions otherwise allowable for an
individual whose adjusted gross income exceeds a specified amount will be
reduced by the lesser of (1) 3% of the excess of the individual's adjusted gross
income over the amount or (2) 80% of the amount of itemized deductions otherwise
allowable for the taxable year. The amount of additional taxable income
reportable by holders of Grantor Trust Fractional Interest Certificates who are
subject to the limitations of either Section 67 or Section 68 of the Code may be
substantial. Further, certificateholders (other than corporations) subject to
the alternative minimum tax may not deduct miscellaneous itemized deductions in
determining the holder's alternative minimum taxable income. Although it is not
entirely clear, it appears that in transactions in which multiple classes of
Grantor Trust Certificates (including Grantor Trust Strip Certificates) are
issued, the fees and expenses should be allocated among the classes of Grantor
Trust Certificates using a method that recognizes that each such class benefits
from the related services. In the absence of statutory or administrative
clarification as to the method to be used, it currently is intended to base
information returns or reports to the IRS and certificateholders on a method
that allocates the expenses among classes of Grantor Trust Certificates with
respect to each period based on the distributions made to each such class during
that period.

                                    - 131 -


         The federal income tax treatment of Grantor Trust Fractional Interest
Certificates of any series will depend on whether they are subject to the
"stripped bond" rules of Section 1286 of the Code. Grantor Trust Fractional
Interest Certificates may be subject to those rules if (1) a class of Grantor
Trust Strip Certificates is issued as part of the same series of certificates or
(2) the depositor or any of its affiliates retains (for its own account or for
purposes of resale) a right to receive a specified portion of the interest
payable on the mortgage loans. Further, the IRS has ruled that an unreasonably
high servicing fee retained by a seller or servicer will be treated as a
retained ownership interest in mortgages that constitutes a stripped coupon. For
purposes of determining what constitutes reasonable servicing fees for various
types of mortgages the IRS has established "safe harbors." The servicing fees
paid with respect to the mortgage loans for a series of Grantor Trust
Certificates may be higher than the "safe harbors" and, accordingly, may not
constitute reasonable servicing compensation. The related prospectus supplement
will include information regarding servicing fees paid to the master servicer,
any subservicer or their respective affiliates necessary to determine whether
the preceding "safe harbor" rules apply.

         IF STRIPPED BOND RULES APPLY. If the stripped bond rules apply, each
Grantor Trust Fractional Interest Certificate will be treated as having been
issued with "original issue discount" within the meaning of Section 1273(a) of
the Code, subject, however, to the discussion below regarding the treatment of
some stripped bonds as market discount bonds and the discussion regarding de
minimis market discount. See "--Taxation of Owners of Grantor Trust Fractional
Interest Certificates--Market Discount" below. Under the stripped bond rules,
the holder of a Grantor Trust Fractional Interest Certificate (whether a cash or
accrual method taxpayer) will be required to report interest income from its
Grantor Trust Fractional Interest Certificate for each month in an amount equal
to the income that accrues on the certificate in that month calculated under a
constant yield method, in accordance with the rules of the Code relating to
original issue discount.

         The original issue discount on a Grantor Trust Fractional Interest
Certificate will be the excess of the certificate's stated redemption price over
its issue price. The issue price of a Grantor Trust Fractional Interest
Certificate as to any purchaser will be equal to the price paid by the purchaser
for the Grantor Trust Fractional Interest Certificate. The stated redemption
price of a Grantor Trust Fractional Interest Certificate will be the sum of all
payments to be made on the certificate, other than "qualified stated interest,"
if any, as well as the certificate's share of reasonable servicing fees and
other expenses. See "--Taxation of Owners of Grantor Trust Fractional Interest
Certificates--If Stripped Bond Rules Do Not Apply" for a definition of
"qualified stated interest." In general, the amount of the income that accrues
in any month would equal the product of the holder's adjusted basis in the
Grantor Trust Fractional Interest Certificate at the beginning of the month (see
"Sales of Grantor Trust Certificates") and the yield of the Grantor Trust
Fractional Interest Certificate to the holder. This yield would be computed at
the rate (compounded based on the regular interval between distribution dates)
that, if used to discount the holder's share of future payments on the mortgage
loans, would cause the present value of those future payments to equal the price
at which the holder purchased the certificate. In computing yield under the
stripped bond rules, a certificateholder's share of future payments on the
mortgage loans will not include any payments made in respect of any ownership
interest in the mortgage loans retained by the depositor, the master servicer,
any subservicer or their respective affiliates, but will include the
certificateholder's share of any reasonable servicing fees and other expenses.

                                    - 132 -


         To the extent the Grantor Trust Fractional Interest Certificates
represent an interest in any pool of debt instruments the yield on which may be
affected by reason of prepayments, for taxable years beginning after August 5,
1997, Section 1272(a)(6) of the Code requires (1) the use of a reasonable
prepayment assumption in accruing original issue discount and (2) adjustments in
the accrual of original issue discount when prepayments do not conform to the
prepayment assumption. It is unclear whether those provisions would be
applicable to the Grantor Trust Fractional Interest Certificates that do not
represent an interest in any pool of debt instruments the yield on which may be
affected by reason of prepayments, or for taxable years beginning prior to
August 5, 1997 or whether use of a reasonable prepayment assumption may be
required or permitted without reliance on these rules. It is also uncertain, if
a prepayment assumption is used, whether the assumed prepayment rate would be
determined based on conditions at the time of the first sale of the Grantor
Trust Fractional Interest Certificate or, with respect to any holder, at the
time of purchase of the Grantor Trust Fractional Interest Certificate by that
holder. Certificateholders are advised to consult their own tax advisors
concerning reporting original issue discount with respect to Grantor Trust
Fractional Interest Certificates and, in particular, whether a prepayment
assumption should be used in reporting original issue discount.

         In the case of a Grantor Trust Fractional Interest Certificate acquired
at a price equal to the principal amount of the mortgage loans allocable to the
certificate, the use of a prepayment assumption generally would not have any
significant effect on the yield used in calculating accruals of interest income.
In the case, however, of a Grantor Trust Fractional Interest Certificate
acquired at a discount or premium (that is, at a price less than or greater than
the principal amount, respectively), the use of a reasonable prepayment
assumption would increase or decrease the yield, and thus accelerate or
decelerate, respectively, the reporting of income.

         If a prepayment assumption is not used, then when a mortgage loan
prepays in full, the holder of a Grantor Trust Fractional Interest Certificate
acquired at a discount or a premium generally will recognize ordinary income or
loss equal to the difference between the portion of the prepaid principal amount
of the mortgage loan that is allocable to the certificate and the portion of the
adjusted basis of the certificate that is allocable to the certificateholder's
interest in the mortgage loan. If a prepayment assumption is used, it appears
that no separate item of income or loss should be recognized upon a prepayment.
Instead, a prepayment should be treated as a partial payment of the stated
redemption price of the Grantor Trust Fractional Interest Certificate and
accounted for under a method similar to that described for taking account of
original issue discount on REMIC Regular Certificates. See "REMICs--Taxation of
Owners of REMIC Regular Certificates--Original Issue Discount." It is unclear
whether any other adjustments would be required to reflect differences between
an assumed prepayment rate and the actual rate of prepayments.

         It is currently intended to base information reports or returns to the
IRS and certificateholders in transactions subject to the stripped bond rules on
a Prepayment Assumption that will be disclosed in the related prospectus
supplement and on a constant yield computed using a representative initial
offering price for each class of certificates. However, none of the depositor,
the master servicer or the trustee will make any representation that the
mortgage loans will in fact prepay at a rate conforming to the Prepayment
Assumption or any other rate and certificateholders should bear in mind that the
use of a representative initial offering price will mean that the information
returns or reports, even if otherwise accepted as accurate by the IRS,



                                    - 133 -


will in any event be accurate only as to the initial certificateholders of each
series who bought at that price.

         Under Treasury regulation Section 1.1286-1, some stripped bonds are to
be treated as market discount bonds and, accordingly, any purchaser of such a
bond is to account for any discount on the bond as market discount rather than
original issue discount. This treatment only applies, however, if immediately
after the most recent disposition of the bond by a person stripping one or more
coupons from the bond and disposing of the bond or coupon (1) there is no
original issue discount (or only a de minimis amount of original issue discount)
or (2) the annual stated rate of interest payable on the original bond is no
more than one percentage point lower than the gross interest rate payable on the
original mortgage loan (before subtracting any servicing fee or any stripped
coupon). If interest payable on a Grantor Trust Fractional Interest Certificate
is more than one percentage point lower than the gross interest rate payable on
the mortgage loans, the related prospectus supplement will disclose that fact.
If the original issue discount or market discount on a Grantor Trust Fractional
Interest Certificate determined under the stripped bond rules is less than 0.25%
of the stated redemption price multiplied by the weighted average maturity of
the mortgage loans, then that original issue discount or market discount will be
considered to be de minimis. Original issue discount or market discount of only
a de minimis amount will be included in income in the same manner as de minimis
original issue and market discount described in "Characteristics of Investments
in Grantor Trust Certificates--If Stripped Bond Rules Do Not Apply" and
"--Market Discount" below.

         IF STRIPPED BOND RULES DO NOT APPLY. Subject to the discussion below on
original issue discount, if the stripped bond rules do not apply to a Grantor
Trust Fractional Interest Certificate, the certificateholder will be required to
report its share of the interest income on the mortgage loans in accordance with
the certificateholder's normal method of accounting. The original issue discount
rules will apply to a Grantor Trust Fractional Interest Certificate to the
extent it evidences an interest in mortgage loans issued with original issue
discount.

         The original issue discount, if any, on the mortgage loans will equal
the difference between the stated redemption price of the mortgage loans and
their issue price. Under the OID Regulations, the stated redemption price is
equal to the total of all payments to be made on the mortgage loan other than
"qualified stated interest." "Qualified stated interest" is interest that is
unconditionally payable at least annually at a single fixed rate, or at a
"qualified floating rate," an "objective rate," a combination of a single fixed
rate and one or more "qualified floating rates" or one "qualified inverse
floating rate," or a combination of "qualified floating rates" that does not
operate in a manner that accelerates or defers interest payments on the mortgage
loan. In general, the issue price of a mortgage loan will be the amount received
by the borrower from the lender under the terms of the mortgage loan, less any
"points" paid by the borrower, and the stated redemption price of a mortgage
loan will equal its principal amount, unless the mortgage loan provides for an
initial below-market rate of interest or the acceleration or the deferral of
interest payments. The determination as to whether original issue discount will
be considered to be de minimis will be calculated using the same test described
in the REMIC discussion. See "--Taxation of Owners of REMIC Regular
Certificates--Original Issue Discount" above.

         In the case of mortgage loans bearing adjustable or variable interest
rates, the related prospectus supplement will describe the manner in which the
rules will be applied with respect to



                                    - 134 -


those mortgage loans by the master servicer or the trustee in preparing
information returns to the certificateholders and the IRS.

         If original issue discount is in excess of a de minimis amount, all
original issue discount with respect to a mortgage loan will be required to be
accrued and reported in income each month, based on a constant yield.
Section1272(a)(6) of the Code requires that a prepayment assumption be made in
computing yield with respect to any pool of debt instruments the yield on which
may be affected by reason of prepayments. Accordingly, for certificates backed
by these pools, it is intended to base information reports and returns to the
IRS and certificateholders for taxable years beginning after August 5, 1997, on
the use of a prepayment assumption. However, in the case of certificates not
backed by these pools or with respect to taxable years beginning prior to August
5, 1997, it currently is not intended to base the reports and returns on the use
of a prepayment assumption. Certificateholders are advised to consult their own
tax advisors concerning whether a prepayment assumption should be used in
reporting original issue discount with respect to Grantor Trust Fractional
Interest Certificates. Certificateholders should refer to the related prospectus
supplement with respect to each series to determine whether and in what manner
the original issue discount rules will apply to mortgage loans in the series.

         A purchaser of a Grantor Trust Fractional Interest Certificate that
purchases the Grantor Trust Fractional Interest Certificate at a cost less than
the certificate's allocable portion of the aggregate remaining stated redemption
price of the mortgage loans held in the related trust fund will also be required
to include in gross income the certificate's daily portions of any original
issue discount with respect to the mortgage loans. However, each such daily
portion will be reduced, if the cost of the Grantor Trust Fractional Interest
Certificate to the purchaser is in excess of the certificate's allocable portion
of the aggregate "adjusted issue prices" of the mortgage loans held in the
related trust fund, approximately in proportion to the ratio the excess bears to
the certificate's allocable portion of the aggregate original issue discount
remaining to be accrued on the mortgage loans. The adjusted issue price of a
mortgage loan on any given day equals the sum of (1) the adjusted issue price
(or, in the case of the first accrual period, the issue price) of the mortgage
loan at the beginning of the accrual period that includes the day and (2) the
daily portions of original issue discount for all days during the accrual period
prior to the day. The adjusted issue price of a mortgage loan at the beginning
of any accrual period will equal the issue price of the mortgage loan, increased
by the aggregate amount of original issue discount with respect to the mortgage
loan that accrued in prior accrual periods, and reduced by the amount of any
payments made on the mortgage loan in prior accrual periods of amounts included
in its stated redemption price.

         In addition to its regular reports, the master servicer or the trustee,
except as provided in the related prospectus supplement, will provide to any
holder of a Grantor Trust Fractional Interest Certificate such information as
the holder may reasonably request from time to time with respect to original
issue discount accruing on Grantor Trust Fractional Interest Certificates. See
"Grantor Trust Reporting" below.

         MARKET DISCOUNT. If the stripped bond rules do not apply to the Grantor
Trust Fractional Interest Certificate, a certificateholder may be subject to the
market discount rules of Sections 1276 through 1278 of the Code to the extent an
interest in a mortgage loan is considered to have been purchased at a "market
discount," that is, in the case of a mortgage loan issued without



                                    - 135 -


original issue discount, at a purchase price less than its remaining stated
redemption price (as defined above), or in the case of a mortgage loan issued
with original issue discount, at a purchase price less than its adjusted issue
price (as defined above). If market discount is in excess of a de minimis amount
(as described below), the holder generally will be required to include in income
in each month the amount of the discount that has accrued (under the rules
described in the next paragraph) through the month that has not previously been
included in income, but limited, in the case of the portion of the discount that
is allocable to any mortgage loan, to the payment of stated redemption price on
the mortgage loan that is received by (or, in the case of accrual basis
certificateholders, due to) the trust fund in that month. A certificateholder
may elect to include market discount in income currently as it accrues (under a
constant yield method based on the yield of the certificate to the holder)
rather than including it on a deferred basis in accordance with the foregoing
under rules similar to those described in "--Taxation of Owners of REMIC Regular
Certificates--Market Discount" above.

         Section 1276(b)(3) of the Code authorized the Treasury Department to
issue regulations providing for the method for accruing market discount on debt
instruments, the principal of which is payable in more than one installment.
Until such time as regulations are issued by the Treasury Department, some rules
described in the Committee Report will apply. Under those rules, in each accrual
period market discount on the mortgage loans should accrue, at the
certificateholder's option: (1) on the basis of a constant yield method, (2) in
the case of a mortgage loan issued without original issue discount, in an amount
that bears the same ratio to the total remaining market discount as the stated
interest paid in the accrual period bears to the total stated interest remaining
to be paid on the mortgage loan as of the beginning of the accrual period, or
(3) in the case of a mortgage loan issued with original issue discount, in an
amount that bears the same ratio to the total remaining market discount as the
original issue discount accrued in the accrual period bears to the total
original issue discount remaining at the beginning of the accrual period. The
prepayment assumption, if any, used in calculating the accrual of original issue
discount is to be used in calculating the accrual of market discount. The effect
of using a prepayment assumption could be to accelerate the reporting of the
discount income. Because the regulations referred to in this paragraph have not
been issued, it is not possible to predict what effect the regulations might
have on the tax treatment of a mortgage loan purchased at a discount in the
secondary market.

         Because the mortgage loans will provide for periodic payments of stated
redemption price, the market discount may be required to be included in income
at a rate that is not significantly slower than the rate at which the discount
would be included in income if it were original issue discount.

         Market discount with respect to mortgage loans may be considered to be
de minimis and, if so, will be includible in income under de minimis rules
similar to those described above in "REMICs--Taxation of Owners of REMIC Regular
Certificates--Original Issue Discount" with the exception that it is less likely
that a prepayment assumption will be used for purposes of these rules with
respect to the mortgage loans.

         Further, under the rules described in "--REMICs--Taxation of Owners of
REMIC Regular Certificates--Market Discount," above, any discount that is not
original issue discount and exceeds a de minimis amount may require the deferral
of interest expense deductions



                                    - 136 -


attributable to accrued market discount not yet includible in income, unless an
election has been made to report market discount currently as it accrues. This
rule applies without regard to the origination dates of the mortgage loans.

         PREMIUM. If a certificateholder is treated as acquiring the underlying
mortgage loans at a premium, that is, at a price in excess of their remaining
stated redemption price, the certificateholder may elect under Section 171 of
the Code to amortize using a constant yield method the portion of the premium
allocable to mortgage loans originated after September 27, 1985. Amortizable
premium is treated as an offset to interest income on the related debt
instrument, rather than as a separate interest deduction. However, premium
allocable to mortgage loans originated before September 28, 1985 or to mortgage
loans for which an amortization election is not made, should be allocated among
the payments of stated redemption price on the mortgage loan and be allowed as a
deduction as these payments are made (or, for a certificateholder using the
accrual method of accounting, when the payments of stated redemption price are
due).

         It is unclear whether a prepayment assumption should be used in
computing amortization of premium allowable under Section 171 of the Code. If
premium is not subject to amortization using a prepayment assumption and a
mortgage loan prepays in full, the holder of a Grantor Trust Fractional Interest
Certificate acquired at a premium should recognize a loss, equal to the
difference between the portion of the prepaid principal amount of the mortgage
loan that is allocable to the certificate and the portion of the adjusted basis
of the certificate that is allocable to the mortgage loan. If a prepayment
assumption is used to amortize premium, it appears that such a loss would be
unavailable. Instead, if a prepayment assumption is used, a prepayment should be
treated as a partial payment of the stated redemption price of the Grantor Trust
Fractional Interest Certificate and accounted for under a method similar to that
described for taking account of original issue discount on REMIC Regular
Certificates. See "REMICs--Taxation of Owners of REMIC Regular
Certificates--Original Issue Discount." It is unclear whether any other
adjustments would be required to reflect differences between the prepayment
assumption used, and the actual rate of prepayments.

         TAXATION OF OWNERS OF GRANTOR TRUST STRIP CERTIFICATES. The "stripped
coupon" rules of Section 1286 of the Code will apply to the Grantor Trust Strip
Certificates. Except as described above in "Characterization of Investments in
Grantor Trust Certificates--If Stripped Bond Rules Apply," no regulations or
published rulings under Section 1286 of the Code have been issued and some
uncertainty exists as to how it will be applied to securities such as the
Grantor Trust Strip Certificates. Accordingly, holders of Grantor Trust Strip
Certificates are encouraged to consult their own tax advisors concerning the
method to be used in reporting income or loss with respect to the certificates.

         The OID Regulations do not apply to "stripped coupons," although they
provide general guidance as to how the original issue discount sections of the
Code will be applied. In addition, the discussion below is subject to the
discussion under "--Possible Application of Contingent Payment Rules" and
assumes that the holder of a Grantor Trust Strip Certificate will not own any
Grantor Trust Fractional Interest Certificates.

                                    - 137 -


         Under the stripped coupon rules, it appears that original issue
discount will be required to be accrued in each month on the Grantor Trust Strip
Certificates based on a constant yield method. In effect, each holder of Grantor
Trust Strip Certificates would include as interest income in each month an
amount equal to the product of the holder's adjusted basis in the Grantor Trust
Strip Certificate at the beginning of that month and the yield of the Grantor
Trust Strip Certificate to the holder. The yield would be calculated based on
the price paid for that Grantor Trust Strip Certificate by its holder and the
payments remaining to be made thereon at the time of the purchase, plus an
allocable portion of the servicing fees and expenses to be paid with respect to
the mortgage loans. See "Characterization of Investments in Grantor Trust
Certificates--If Stripped Bond Rules Apply" above.

         As noted above, Section 1272(a)(6) of the Code requires that a
prepayment assumption be used in computing the accrual of original issue
discount with respect to some categories of debt instruments, and that
adjustments be made in the amount and rate of accrual of the discount when
prepayments do not conform to the prepayment assumption. To the extent the
Grantor Trust Strip Certificates represent an interest in any pool of debt
instruments the yield on which may be affected by reason of prepayments, those
provisions will apply to the Grantor Trust Strip Certificates for taxable years
beginning after August 5, 1997. It is unclear whether those provisions would be
applicable to the Grantor Trust Strip Certificates that do not represent an
interest in any such pool or for taxable years beginning prior to August 5,
1997, or whether use of a prepayment assumption may be required or permitted in
the absence of these provisions. It is also uncertain, if a prepayment
assumption is used, whether the assumed prepayment rate would be determined
based on conditions at the time of the first sale of the Grantor Trust Strip
Certificate or, with respect to any subsequent holder, at the time of purchase
of the Grantor Trust Strip Certificate by that holder.

         The accrual of income on the Grantor Trust Strip Certificates will be
significantly slower if a prepayment assumption is permitted to be made than if
yield is computed assuming no prepayments. It currently is intended to base
information returns or reports to the IRS and certificateholders on the
prepayment Assumption disclosed in the related prospectus supplement and on a
constant yield computed using a representative initial offering price for each
class of certificates. However, none of the depositor, the master servicer or
the trustee will make any representation that the mortgage loans will in fact
prepay at a rate conforming to the Prepayment Assumption or at any other rate
and certificateholders should bear in mind that the use of a representative
initial offering price will mean that the information returns or reports, even
if otherwise accepted as accurate by the IRS, will in any event be accurate only
as to the initial certificateholders of each series who bought at that price.
Prospective purchasers of the Grantor Trust Strip Certificates are encouraged to
consult their own tax advisors regarding the use of the Prepayment Assumption.

         It is unclear under what circumstances, if any, the prepayment of a
mortgage loan will give rise to a loss to the holder of a Grantor Trust Strip
Certificate. If a Grantor Trust Strip Certificate is treated as a single
instrument (rather than an interest in discrete mortgage loans) and the effect
of prepayments is taken into account in computing yield with respect to the
Grantor Trust Strip Certificate, it appears that no loss may be available as a
result of any particular prepayment unless prepayments occur at a rate faster
than the Prepayment Assumption. However, if a Grantor Trust Strip Certificate is
treated as an interest in discrete



                                    - 138 -


mortgage loans, or if the Prepayment Assumption is not used, then when a
mortgage loan is prepaid, the holder of a Grantor Trust Strip Certificate should
be able to recognize a loss equal to the portion of the adjusted issue price of
the Grantor Trust Strip Certificate that is allocable to the mortgage loan.

         POSSIBLE APPLICATION OF CONTINGENT PAYMENT RULES. The coupon stripping
rules' general treatment of stripped coupons is to regard them as newly issued
debt instruments in the hands of each purchaser. To the extent that payments on
the Grantor Trust Strip Certificates would cease if the mortgage loans were
prepaid in full, the Grantor Trust Strip Certificates could be considered to be
debt instruments providing for contingent payments. Under the OID Regulations,
debt instruments providing for contingent payments are not subject to the same
rules as debt instruments providing for noncontingent payments. Regulations were
promulgated on June 14, 1996, regarding contingent payment debt instruments (the
"Contingent Payment Regulations"), but it appears that Grantor Trust Strip
Certificates, to the extent subject to Section 1272(a)(6) of the Code, as
described above, or due to their similarity to other mortgage-backed
securities(such as REMIC regular interests and debt instruments subject to
Section 1272(a)(6) of the Code) that are expressly excepted from the application
of the Contingent Payment Regulations, are or may be excepted from these
regulations. Like the OID Regulations, the Contingent Payment Regulations do not
specifically address securities, such as the Grantor Trust Strip Certificates,
that are subject to the stripped bond rules of Section 1286 of the Code.

         If the contingent payment rules under the Contingent Payment
Regulations were to apply, the holder of a Grantor Trust Strip Certificate would
be required to apply the "noncontingent bond method." Under the "noncontingent
bond method," the issuing entity of a Grantor Trust Strip Certificate determines
a projected payment schedule on which interest will accrue. Holders of Grantor
Trust Strip Certificates are bound by the issuing entity's projected payment
schedule. The projected payment schedule consists of all noncontingent payments
and a projected amount for each contingent payment based on the projected yield
(as described below) of the Grantor Trust Strip Certificate. The projected
amount of each payment is determined so that the projected payment schedule
reflects the projected yield. The projected amount of each payment must
reasonably reflect the relative expected values of the payments to be received
by the holder of a Grantor Trust Strip Certificate. The projected yield referred
to above is a reasonable rate, not less than the "applicable Federal rate" that,
as of the issue date, reflects general market conditions, the credit quality of
the issuing entity, and the terms and conditions of the mortgage loans. The
holder of a Grantor Trust Strip Certificate would be required to include as
interest income in each month the adjusted issue price of the Grantor Trust
Strip Certificate at the beginning of the period multiplied by the projected
yield, and would add to, or subtract from, the income any variation between the
payment actually received in that month and the payment originally projected to
be made in that month.

         Assuming that a prepayment assumption were used, if the Contingent
Payment Regulations or their principles were applied to Grantor Trust Strip
Certificates, the amount of income reported with respect thereto would be
substantially similar to that described under "Taxation of Owners of Grantor
Trust Strip Certificates". Certificateholders are encouraged to consult their
tax advisors concerning the possible application of the contingent payment rules
to the Grantor Trust Strip Certificates.

                                    - 139 -


         SALES OF GRANTOR TRUST CERTIFICATES. Any gain or loss equal to the
difference between the amount realized on the sale or exchange of a Grantor
Trust Certificate and its adjusted basis, recognized on the sale or exchange of
a Grantor Trust Certificate by an investor who holds the Grantor Trust
Certificate as a capital asset, will be capital gain or loss, except to the
extent of accrued and unrecognized market discount, which will be treated as
ordinary income, and (in the case of banks and other financial institutions)
except as provided under Section 582(c) of the Code. The adjusted basis of a
Grantor Trust Certificate generally will equal its cost, increased by any income
reported by the seller (including original issue discount and market discount
income) and reduced (but not below zero) by any previously reported losses, any
amortized premium and by any distributions with respect to the Grantor Trust
Certificate.

         Gain or loss from the sale of a Grantor Trust Certificate may be
partially or wholly ordinary and not capital in some circumstances. Gain
attributable to accrued and unrecognized market discount will be treated as
ordinary income, as will gain or loss recognized by banks and other financial
institutions subject Section 582(c) of the Code. Furthermore, a portion of any
gain that might otherwise be capital gain may be treated as ordinary income to
the extent that the Grantor Trust Certificate is held as part of a "conversion
transaction" within the meaning of Section 1258 of the Code. A conversion
transaction generally is one in which the taxpayer has taken two or more
positions in the same or similar property that reduce or eliminate market risk,
if substantially all of the taxpayer's return is attributable to the time value
of the taxpayer's net investment in the transaction. The amount of gain realized
in a conversion transaction that is recharacterized as ordinary income generally
will not exceed the amount of interest that would have accrued on the taxpayer's
net investment at 120% of the appropriate "applicable Federal rate" (which rate
is computed and published monthly by the IRS) at the time the taxpayer enters
into the conversion transaction, subject to appropriate reduction for prior
inclusion of interest and other ordinary income items from the transaction.
Finally, a taxpayer may elect to have net capital gain taxed at ordinary income
rates rather than capital gains rates in order to include the net capital gain
in total net investment income for that taxable year, for purposes of the rule
that limits the deduction of interest on indebtedness incurred to purchase or
carry property held for investment to a taxpayer's net investment income.

         GRANTOR TRUST REPORTING. The master servicer or the trustee will
furnish to each holder of a Grantor Trust Fractional Interest Certificate with
each distribution a statement setting forth the amount of the distribution
allocable to principal on the underlying mortgage loans and to interest thereon
at the related pass-through rate. In addition, the master servicer or the
trustee will furnish, within a reasonable time after the end of each calendar
year, to each holder of a Grantor Trust Certificate who was a holder at any time
during that year, information regarding the amount of servicing compensation
received by the master servicer and subservicer (if any) and any other customary
factual information as the master servicer or the trustee deems necessary or
desirable to enable holders of Grantor Trust Certificates to prepare their tax
returns and will furnish comparable information to the IRS as and when required
by law to do so. Because the rules for accruing discount and amortizing premium
with respect to the Grantor Trust Certificates are uncertain in various
respects, there is no assurance the IRS will agree with the trust fund's
information reports of these items of income and expense. Moreover, these
information reports, even if otherwise accepted as accurate by the IRS, will in
any event be accurate only as to the initial certificateholders that bought
their certificates at the representative initial offering price used in
preparing the reports.

                                    - 140 -


         Except as disclosed in the related prospectus supplement, the
responsibility for complying with the foregoing reporting rules will be borne by
the master servicer or the trustee.

         BACKUP WITHHOLDING. In general, the rules described in "REMICS--Backup
Withholding with Respect to REMIC Certificates" will also apply to Grantor Trust
Certificates.

         FOREIGN INVESTORS. In general, the discussion with respect to REMIC
Regular certificates in "REMICS--Foreign Investors in REMIC Certificates"
applies to Grantor Trust Certificates except that Grantor Trust Certificates
will, except as disclosed in the related prospectus supplement, be eligible for
exemption from U.S. withholding tax, subject to the conditions described in the
discussion, only to the extent the related mortgage loans were originated after
July 18, 1984.

         To the extent that interest on a Grantor Trust Certificate would be
exempt under Sections 871(h)(1) and 881(c) of the Code from United States
withholding tax, and the Grantor Trust Certificate is not held in connection
with a certificateholder's trade or business in the United States, the Grantor
Trust Certificate will not be subject to United States estate taxes in the
estate of a non-resident alien individual.

                        STATE AND OTHER TAX CONSEQUENCES

         In addition to the federal income tax consequences described in
"Federal Income Tax Consequences", potential investors should consider the state
and local tax consequences of the acquisition, ownership, and disposition of the
securities offered under this prospectus and the prospectus supplement. State
tax and local law may differ substantially from the corresponding federal tax
law, and the discussion above does not purport to describe any aspect of the tax
laws of any state or other jurisdiction. Therefore, prospective investors are
encouraged consult their own tax advisors with respect to the various state and
other tax consequences of investments in the securities offered under this
prospectus and the prospectus supplement.

                              ERISA CONSIDERATIONS

         Sections 404 and 406 of ERISA impose fiduciary and prohibited
transaction restrictions on ERISA Plans and on various other retirement plans
and arrangements, including bank collective investment funds and insurance
company general and separate accounts in which ERISA Plans are invested. Section
4975 of the Code imposes essentially the same prohibited transaction
restrictions on Tax Favored Plans. ERISA and the Code prohibit a broad range of
transactions involving assets of Plans and persons having obtained certain
relationships to a Plan, called "Parties in Interest", unless a statutory or
administrative exemption is available with respect to any such transaction.

         Some employee benefit plans, including governmental plans (as defined
in Section 3(32) of ERISA), and, if no election has been made under Section
410(d) of the Code, church plans (as defined in Section 3(33) of ERISA) are not
subject the ERISA requirements. Accordingly, assets of these plans may be
invested in the securities without regard to the ERISA considerations described
below, subject to the provisions of other applicable federal, state and local
law. Any such plan which is qualified and exempt from taxation under Sections
401(a) and 501(a) of the Code, however, is subject to the prohibited transaction
rules set forth in Section 503 of the Code.

                                    - 141 -


         ERISA generally imposes on Plan fiduciaries general fiduciary
requirements, including those of investment prudence and diversification and the
requirement that a Plan's investments be made for the exclusive benefit of Plan
participants and their beneficiaries and in accordance with the documents
governing the Plan. Any person who has discretionary authority or control with
respect to the management or disposition of a Plan's assets, or "Plan Assets,"
and any person who provides investment advice with respect to Plan Assets for a
fee is a fiduciary of the investing Plan. If the mortgage loans and other assets
included in the trust fund were to constitute Plan Assets, then any party
exercising management or discretionary control with respect to those Plan Assets
may be deemed to be a Plan "fiduciary," and thus subject to the fiduciary
responsibility provisions of ERISA and the prohibited transaction provisions of
ERISA and Section 4975 of the Code with respect to any investing Plan. In
addition, the acquisition or holding of securities by or on behalf of a Plan or
with Plan Assets, as well as the operation of the trust fund, may constitute or
involve a prohibited transaction under ERISA and the Code unless a statutory or
administrative exemption is available. Further, ERISA and the Code prohibit a
broad range of transactions involving Plan Assets and Parties in Interest unless
a statutory or administrative exemption is available. Some Parties in Interest
that participate in a prohibited transaction may be subject to a penalty (or an
excise tax) imposed under Section 502(i) of ERISA or Section 4975 of the Code,
unless a statutory or administrative exemption is available with respect to any
transaction of this sort.

         Some transactions involving the trust fund might be deemed to
constitute prohibited transactions under ERISA and the Code with respect to a
Plan that purchases the securities, if the mortgage loans and other assets
included in a trust fund are deemed to be assets of the Plan. The DOL has
promulgated the DOL Regulations concerning whether or not a Plan's assets would
be deemed to include an interest in the underlying assets of an entity,
including a trust fund, for purposes of applying the general fiduciary
responsibility provisions of ERISA and the prohibited transaction provisions of
ERISA and the Code. Under the DOL Regulations, generally, when a Plan acquires
an "equity interest" in another entity (such as the trust fund), the underlying
assets of that entity may be considered to be Plan Assets unless an exception
applies. Exceptions contained in the DOL Regulations provide that Plan Assets
will not include an undivided interest in each asset of an entity in which the
Plan makes an equity investment if: (1) the entity is an operating company; (2)
the equity investment made by the Plan is either a "publicly-offered security"
that is "widely held," both as defined in the DOL Regulations, or a security
issued by an investment company registered under the Investment Company Act of
1940, as amended; or (3) Benefit Plan Investors do not own 25% or more in value
of any class of equity securities issued by the entity. In addition, the DOL
Regulations provide that the term "equity interest" means any interest in an
entity other than an instrument which is treated as indebtedness under
applicable local law and which has no "substantial equity features." Under the
DOL Regulations, Plan Assets will be deemed to include an interest in the
instrument evidencing the equity interest of a Plan (such as a certificate or a
note with "substantial equity features"), and, because of the factual nature of
some of the rules set forth in the DOL Regulations, Plan Assets may be deemed to
include an interest in the underlying assets of the entity in which a Plan
acquires an interest (such as the trust fund). Without regard to whether the
securities are characterized as equity interests, the purchase, sale and holding
of notes by or on behalf of a Plan could be considered to give rise to a
prohibited transaction if the Issuing Entity, the trustee or any of their
respective affiliates is or becomes a Party in Interest with respect to the
Plan. Neither Plans nor persons



                                    - 142 -


investing Plan Assets should acquire or hold securities in reliance upon the
availability of any exception under the DOL Regulations.

CLASS EXEMPTIONS

         The DOL has issued Prohibited Transaction Class Exemptions ("PTCEs")
which provide exemptive relief to parties to any transaction which satisfies the
conditions of the exemption. A partial listing of the PTCEs which may be
available for investments in securities follows. Each of these exemptions is
available only if specified conditions are satisfied and may provide relief for
some, but not all, of the prohibited transactions that a particular transaction
may cause. The prospectus supplement for a particular offering of securities may
tell you whether the securities themselves satisfy the conditions of these
exemptions. You should consult with your advisors regarding the specific scope,
terms and conditions of an exemption as it applies to you, as an investor,
before relying on that exemption's availability.

         CLASS EXEMPTIONS FOR PURCHASES AND SALES OF SECURITIES.

         The following exemptions may apply to a purchase or sale of securities
between a Plan, on the one hand, and a Party in Interest, on the other hand:

         o        PTCE 84-14, which exempts certain transactions approved on
                  behalf of the Plan by a qualified professional asset manager.


         o        PTCE 86-128, which exempts certain transactions between a Plan
                  and certain broker-dealers.

         o        PTCE 90-1, which exempts certain transactions entered into by
                  insurance company pooled separate accounts in which Plans have
                  made investments.


         o        PTCE 91-38, which exempts certain transactions entered into by
                  bank collective investment funds in which Plans have made
                  investments.


         o        PTCE 96-23, which exempts certain transaction approved on
                  behalf of a Plan by an in-house investment manager.

         These exemptions do not expressly address prohibited transactions that
might result from transactions incidental to the operation of a trust. The
issuing entity cannot assure you that a purchase or sale of securities in
reliance on one of these exemptions will not give rise to indirect, non-exempt
prohibited transactions.

         CLASS EXEMPTIONS FOR PURCHASES AND SALES OF SECURITIES AND TRANSACTIONS
INCIDENTAL TO THE OPERATION OF THE TRUST.

                                    - 143 -


         The following exemptions may apply to a purchase or sale of securities
between a Plan, on the one hand, and a Party in Interest, on the other hand, and
may also apply to prohibited transactions that may result from transactions
incident to the operation of the trust:

         o        PTCE 95-60, which exempts certain transactions involving
                  insurance company general accounts.


         o        PTCE 83-1, which exempts certain transactions involving the
                  purchase of pass-through certificates in mortgage pool
                  investment trusts from, and the sale of such certificates to,
                  the pool sponsor, as well as transactions in connection with
                  the servicing and operation of the pool.

         PROHIBITED TRANSACTION CLASS EXEMPTION 83-1. The U.S. Department of
Labor has issued an administrative exemption, Prohibited Transaction Class
Exemption 83-1 ("PTCE 83-1"), which, under certain conditions, exempts from the
application of the prohibited transaction rules of ERISA and the excise tax
provisions of Section 4975 of the Code transactions involving a Plan in
connection with the operation of a "mortgage pool" and the purchase, sale and
holding of "mortgage pool pass-through certificates." A "mortgage pool" is
defined as an investment pool, consisting solely of interest bearing obligations
secured by first or second mortgages or deeds of trust on single-family
residential property, property acquired in foreclosure and undistributed cash. A
"mortgage pool pass-through certificate" is defined as a certificate which
represents a beneficial undivided interest in a mortgage pool which entitles the
holder to pass-through payments of principal and interest from the mortgage
loans.

         For the exemption to apply, PTCE 83-1 requires that:

         o        the depositor and the trustee maintain a system of insurance
                  or other protection for the mortgage loans and the property
                  securing such mortgage loans, and for indemnifying holders of
                  certificates against reductions in pass-through payments due
                  to defaults in loan payments or property damage in an amount
                  at least equal to the greater of 1% of the aggregate principal
                  balance of the mortgage loans, or 1% of the principal balance
                  of the largest covered pooled mortgage loan;

         o        the trustee may not be an affiliate of the depositor;

         o        and the payments made and retained by the depositor in
                  connection with the trust fund, together with all funds
                  inuring to the depositor's benefit for administering the trust
                  fund, represent no more than "adequate consideration" for
                  selling the mortgage loans, plus reasonable compensation for
                  services provided to the trust fund.

         In addition, if it is applicable, PTCE 83-1 exempts the initial sale of
certificates to a Plan with respect to which the depositor, the special hazard
insurer, the pool insurer, the master servicer, or other servicer, or the
trustee are or is a party in interest if the Plan does not pay more than fair
market value for such certificate and the rights and interests evidenced by such
certificate are not subordinated to the rights and interests evidenced by other
certificates of the same pool. PTCE 83-1 also exempts from the prohibited
transaction rules any transactions in



                                    - 144 -


connection with the servicing and operation of the mortgage pool, provided that
any payments made to the master servicer in connection with the servicing of the
trust fund are made in accordance with a binding agreement, copies of which must
be made available to prospective investors.

         In the case of any Plan with respect to which the depositor, the master
servicer, the special hazard insurer, the pool insurer, or the trustee is a
fiduciary, PTCE 83-1 will only apply if, in addition to the other requirements:

         o        the initial sale, exchange or transfer of certificates is
                  expressly approved by an independent fiduciary who has
                  authority to manage and control those plan assets being
                  invested in certificates;

         o        the Plan pays no more for the certificates than would be paid
                  in an arm's length transaction;

         o        no investment management, advisory or underwriting fee, sale
                  commission, or similar compensation is paid to the depositor
                  with regard to the sale, exchange or transfer of certificates
                  to the Plan;

         o        the total value of the certificates purchased by such Plan
                  does not exceed 25% of the amount issued; and

         o        at least 50% of the aggregate amount of certificates is
                  acquired by persons independent of the depositor, the trustee,
                  the master servicer, and the special hazard insurer or pool
                  insurer.

         Before purchasing certificates, a fiduciary of a Plan should confirm
that the trust fund is a "mortgage pool," that the certificates constitute
"mortgage pool pass-through certificates," and that the conditions set forth in
PTCE 83-1 would be satisfied. In addition to making its own determination as to
the availability of the exemptive relief provided in PTCE 83-1, the Plan
fiduciary should consider the availability of any other prohibited transaction
exemptions. The Plan fiduciary also should consider its general fiduciary
obligations under ERISA in determining whether to purchase any certificates on
behalf of a Plan.

UNDERWRITER EXEMPTION

         The DOL has issued Exemptions to some underwriters, which generally
exempt from the application of the prohibited transaction provisions of Section
406 of ERISA, and the excise taxes imposed on those prohibited transactions
pursuant to Section 4975(a) and (b) of the Code, some transactions, among
others, relating to the servicing and operation of mortgage pools and the
initial purchase, holding and subsequent resale of mortgage pass-through
certificates or other "securities" underwritten by an Underwriter, as defined
below, provided that the conditions set forth in the Exemption are satisfied.
For purposes of this section "ERISA Considerations", the term "Underwriter"
shall include (1) the underwriter, (2) any person directly or indirectly,
through one or more intermediaries, controlling, controlled by or under common
control with the



                                    - 145 -


underwriter and (3) any member of the underwriting syndicate or selling group of
which a person described in (1) or (2) is a manager or co-manager with respect
to a class of securities.

         GENERAL CONDITIONS OF EXEMPTION. The Exemption sets forth six general
conditions which must be satisfied for the Exemption to apply.

         First, the acquisition of securities by a Plan or with Plan Assets must
be on terms that are at least as favorable to the Plan as they would be in an
arm's-length transaction with an unrelated party.

         Second, the Exemption applies only to securities evidencing rights and
interests that are not subordinated to the rights and interests evidenced by
other securities of the same trust, unless none of the mortgage loans has a
Loan-to-Value Ratio at the date of issuance of the securities that exceeds 100%.

         Third, the securities at the time of acquisition by a Plan or with Plan
Assets must be rated in one of the four highest generic rating categories by an
Exemption Rating Agency. However, the securities must be rated in one of the two
highest generic categories by an Exemption Rating Agency if the Loan-to-Value
Ratio of any one- to four-family residential mortgage loan or home equity loan
held in the trust exceeds 100% but does not exceed 125% at the date of issuance
of the securities, and in that case the Exemption will not apply: (1) to any of
the securities if any mortgage loan or other asset held in the trust (other than
a one- to four-family residential mortgage loan or home equity loan) has a
Loan-to-Value Ratio that exceeds 100% at the Closing Date or (2) to any
subordinate securities.

         Fourth, the trustee cannot be an affiliate of any member of the
"Restricted Group" other than the Underwriter. The Restricted Group consists of
any Underwriter, the depositor, the master servicer, the special servicer, any
servicer, any counterparty to an "eligible swap" (as described below) and any
obligor with respect to assets included in the trust fund constituting more than
5% of the aggregate unamortized principal balance of the assets in the trust
fund as of the date of initial issuance of the securities.

         Fifth, the sum of all payments made to and retained by the Underwriter
or Underwriters must represent not more than reasonable compensation for
underwriting the securities; the sum of all payments made to and retained by the
depositor pursuant to the assignment of the assets to the related trust fund
must represent not more than the fair market value of the obligations; and the
sum of all payments made to and retained by the master servicer, the special
servicer and any servicer must represent not more than reasonable compensation
for the person's services under the related Agreement and reimbursement of the
person's reasonable expenses in connection therewith.

         Sixth, the investing Plan or Plan Asset investor must be an accredited
investor as defined in Rule 501(a)(1) of Regulation D of the Commission under
the Securities Act.

         INSURANCE COMPANY GENERAL ACCOUNTS.

         In the event that securities which are certificates, but not notes, do
not meet the requirements of the Exemption solely because they are subordinate
certificates or fail to meet a minimum rating requirements under the Exemption,
certain Plans may be eligible to purchase certificates pursuant to Sections I
and III of PTCE 95-60 which permits insurance company general accounts as
defined in PTCE 95-60 to purchase such certificates if they otherwise meet all
of the other requirements of the Exemption.

         CERTAIN PERMITTED ASSETS.

                                    - 146 -


         The Exemption permits an interest rate swap or yield supplement
agreement to be held by the trust if it meets the conditions of the Exemption.

         An interest-rate swap (a "swap" or "swap agreement") is a permitted
trust fund asset if it: (a) is an "eligible swap;" (b) is with an "eligible
counterparty;" (c) is purchased by a "qualified plan investor;" (d) meets
certain additional specific conditions which depend on whether the swap is a
"ratings dependent swap" or a "non-ratings dependent swap" and (e) permits the
trust to make termination payments to the swap counterparty (other than
currently scheduled payments) solely from excess spread or amounts otherwise
payable to the servicer, depositor or seller.

         An "eligible swap" is one which: (a) is denominated in U.S. dollars;
(b) pursuant to which the trust pays or receives, on or immediately prior to the
respective payment or distribution date for the class of securities to which the
swap relates, a fixed rate of interest or a floating rate of interest based on a
publicly available index (e.g., LIBOR or the U.S. Federal Reserve's Cost of
Funds Index (COFI)), with the trust receiving such payments on at least a
quarterly basis and obligated to make separate payments no more frequently than
the counterparty, with all simultaneous payments being netted ("allowable
interest rate"); (c) has a notional amount that does not exceed either: (i) the
principal balance of the class of securities to which the swap relates, or (ii)
the portion of the principal balance of such class represented by obligations
("allowable notional amount"); (d) is not leveraged (i.e., payments are based on
the applicable notional amount, the day count fractions, the fixed or floating
rates permitted above, and the difference between the products thereof,
calculated on a one-to-one ratio and not on a multiplier of such difference)
("leveraged"); (e) has a final termination date that is either the earlier of
the date on which the issuer terminates or the related class of securities are
fully repaid and (f) does not incorporate any provision which could cause a
unilateral alteration in the requirements described in (a) through (d) above.
         An "eligible counterparty" means a bank or other financial institution
which has a rating at the date of issuance of the securities, which is in one of
the three highest long term credit rating categories or one of the two highest
short term credit rating categories, utilized by at least one of the Exemption
Rating Agencies rating the securities; provided that, if a counterparty is
relying on its short term rating to establish eligibility hereunder, such
counterparty must either have a long term rating in one of the three highest
long term rating categories or not have a long term rating from the applicable
Exemption Rating Agency.

         A "qualified plan investor" is a plan where the decision to buy such
class of securities is made on behalf of the plan by an independent fiduciary
qualified to understand the swap transaction and the effect the swap would have
on the rating of the securities and such fiduciary is either (a) a "qualified
professional asset manager" ("QPAM") under PTCE 84-14, (b) an "in-house asset
manager" under PTCE 96-23 or (c) has total assets (both plan and non-plan) under
management of at least $100 million at the time the securities are acquired by
the plan.

         In "ratings dependent swaps" (where the rating of a class of securities
is dependent on the terms and conditions of the swap), the swap agreement must
provide that if the credit rating of the counterparty is withdrawn or reduced by
any Exemption Rating Agency below a level specified by the Exemption Rating
Agency, the servicer must, within the period specified under



                                    - 147 -


the Pooling and Servicing Agreement: (a) obtain a replacement swap agreement
with an eligible counterparty which is acceptable to the Exemption Rating Agency
and the terms of which are substantially the same as the current swap agreement
(at which time the earlier swap agreement must terminate); or (b) cause the swap
counterparty to establish any collateralization or other arrangement
satisfactory to the Exemption Rating Agency such that the then current rating by
the Exemption Rating Agency of the particular class of securities will not be
withdrawn or reduced (and the terms of the swap agreement must specifically
obligate the counterparty to perform these duties for any class of securities
with a term of more than one year). In the event that the servicer fails to meet
these obligations, holders of the securities that are employee benefit plans or
other retirement arrangements must be notified in the immediately following
periodic report which is provided to the holders of the securities but in no
event later than the end of the second month beginning after the date of such
failure. Sixty days after the receipt of such report, the exemptive relief
provided under the Exemption will prospectively cease to be applicable to any
class of securities held by an employee benefit plan or other retirement
arrangement which involves such ratings dependent swap.

         "Non-ratings dependent swaps" (those where the rating of the securities
does not depend on the terms and conditions of the swap) are subject to the
following conditions. If the credit rating of the counterparty is withdrawn or
reduced below the lowest level permitted above, the servicer will, within a
specified period after such rating withdrawal or reduction: (a) obtain a
replacement swap agreement with an eligible counterparty, the terms of which are
substantially the same as the current swap agreement (at which time the earlier
swap agreement must terminate); (b) cause the counterparty to post collateral
with the trust in an amount equal to all payments owed by the counterparty if
the swap transaction were terminated; or (c) terminate the swap agreement in
accordance with its terms.

         A yield supplement agreement is a permitted trust fund asset if it
satisfies the conditions of an "eligible yield supplement agreement." Generally,
any yield supplement agreement will be an eligible yield supplement agreement,
provided that if such yield supplement agreement is an interest rate cap
contract, a corridor contract or similar arrangement with a notional principal
amount and is purchased by or on behalf of the trust to supplement the interest
rates otherwise payable on obligations held by the trust fund, then such yield
supplement agreement will be an eligible yield supplement agreement only if it
meets the following conditions: (a) it is denominated in U.S. dollars; (b) it
pays an allowable interest rate; (c) it is not leveraged; (d) it does not allow
any of these three preceding requirements to be unilaterally altered without the
consent of the trustee; (e) it is entered into between the trust and an eligible
counterparty and (f) it has an allowable notional amount.

         Permitted trust funds include owner-trusts, as well as grantor-trusts
and REMICs and FASITs. Owner-trusts are subject to certain restrictions in their
governing documents to ensure that their assets may not be reached by creditors
of the depositor in the event of bankruptcy or other insolvency and must provide
certain legal opinions.

         The Exemption also requires that the trust fund meet the following
requirements: (1) the trust fund must consist solely of assets of the type that
have been included in other investment pools; (2) securities evidencing
interests in the other investment pools must have been rated in one of the four
highest generic categories of one of the Exemption Rating Agencies for at least


                                    - 148 -


one year prior to the acquisition of securities by or on behalf of a Plan or
with Plan Assets; and (3) securities evidencing interests in the other
investment pools must have been purchased by investors other than Plans for at
least one year prior to any acquisition of securities by or on behalf of a Plan
or with Plan Assets.

         A fiduciary of a Plan or any person investing Plan Assets to purchase a
security must make its own determination that the conditions set forth above
will be satisfied with respect to the security.

         If the general conditions of the Exemption are satisfied, the Exemption
may provide an exemption from the restrictions imposed by Sections 406(a) and
407(a) of ERISA, and the excise taxes imposed by Sections 4975(a) and (b) of the
Code by reason of Sections 4975(c)(1)(A) through (D) of the Code, in connection
with the direct or indirect sale, exchange or transfer of securities in the
initial issuance of the securities or the direct or indirect acquisition or
disposition in the secondary market of securities by a Plan or with Plan Assets
or the continued holding of securities acquired by a Plan or with Plan Assets
pursuant to either of the foregoing. However, no exemption is provided from the
restrictions of Sections 406(a)(1)(E), 406(a)(2) and 407 of ERISA for the
acquisition or holding of a Security on behalf of an "Excluded Plan" by any
person who has discretionary authority or renders investment advice with respect
to the assets of an Excluded Plan. For purposes of the securities, an Excluded
Plan is a Plan sponsored by any member of the Restricted Group.

If the specific conditions of the Exemption are also satisfied, the Exemption
may provide an exemption from the restrictions imposed by Sections 406(b)(1) and
(b)(2) of ERISA, and the excise taxes imposed by Sections 4975(a) and (b) of the
Code by reason of Section 4975(c)(1)(E) of the Code, in connection with:

         o        The direct or indirect sale, exchange or transfer of
                  securities in the initial issuance of securities between the
                  depositor or an Underwriter and a Plan when the person who has
                  discretionary authority or renders investment advice with
                  respect to the investment of Plan Assets in the securities is:

                  (1)      A mortgagor with respect to 5% or less of the fair
                           market value of the trust fund assets or

                  (2)      An affiliate of such a person, provided that: (a) the
                           Plan is not an Excluded Plan; (b) each Plan's
                           investment in each class of securities does not
                           exceed 25% of the outstanding securities in the
                           class; (c) after the Plan's acquisition of the
                           securities, no more than 25% of the assets over which
                           the fiduciary has investment authority are invested
                           in securities of a trust fund containing assets which
                           are sold or serviced by the same entity; and (d) in
                           the case of initial issuance (but not secondary
                           market transactions), at least 50% of each class of
                           securities and at least 50% of the aggregate
                           interests in the trust fund are acquired by persons
                           independent of the Restricted Group;

                                    - 149 -


         o        The direct or indirect acquisition or disposition in the
                  secondary market of securities by a Plan or with Plan assets
                  provided that the conditions in (2)(a), (c) and (d) above are
                  met; and

         The continued holding of securities acquired by a Plan or with Plan
Assets in an initial issuance or secondary market transaction meeting the
foregoing requirements.

         Further, if the specific conditions of the Exemption are satisfied, the
Exemption may provide an exemption from the restrictions imposed by Sections
406(a), 406(b) and 407 of ERISA, and the excise taxes imposed by Sections
4975(a) and (b) of the Code by reason of Section 4975(c) of the Code for
transactions in connection with the servicing, management and operation of the
trust fund. The depositor expects that the specific conditions of the Exemption
required for this purpose will be satisfied with respect to the securities so
that the Exemption would provide an exemption from the restrictions imposed by
Sections 406(a) and (b) of ERISA (as well as the excise taxes imposed by
Sections 4975(a) and (b) of the Code by reason of Section 4975(c) of the Code)
for transactions in connection with the servicing, management and operation of
the trust fund, provided that the general conditions of the Exemption are
satisfied.

         The Exemption also may provide an exemption from the application of the
prohibited transaction provisions of Sections 406(a) and 407(a) of ERISA, and
the excise taxes imposed by Section 4975(a) and (b) of the Code by reason of
Sections 4975(c)(1)(A) through (D) of the Code if the restrictions are deemed to
otherwise apply merely because a person is deemed to be a Party in Interest with
respect to an investing Plan by virtue of providing services to the Plan (or by
virtue of having a specified relationship to such a person) solely as a result
of the Plan's ownership of securities.

         The Exemption generally extends exemptive relief to mortgage-backed and
asset-backed securities transactions using pre-funding accounts for trusts
issuing securities. With respect to the securities, the Exemption will generally
allow mortgage loans supporting payments to securityholders, and having a value
equal to no more than 25% of the total principal amount of the securities being
offered by a trust fund, to be transferred to the trust fund within the
Pre-Funding Period instead of requiring that all the mortgage loans be either
identified or transferred on or before the Closing Date. In general, the relief
applies to the purchase, sale and holding of securities which otherwise qualify
for the Exemption, provided that the following general conditions are met:

         o        as mentioned, the ratio of the amount allocated to the
                  pre-funding account to the total principal amount of the
                  securities being offered must be less than or equal to 25%;

         o        all additional mortgage loans transferred to the related trust
                  fund after the Closing Date must meet the same terms and
                  conditions for eligibility as the original mortgage loans used
                  to create the trust fund, which terms and conditions have been
                  approved by one of the Exemption Rating Agencies;

         o        the transfer of the additional mortgage loans to the trust
                  fund during the Pre-Funding Period must not result in the
                  securities to be covered by the



                                    - 150 -


                  Exemptions receiving a lower credit rating from an Exemption
                  Rating Agency upon termination of the Pre-Funding Period than
                  the rating that was obtained at the time of the initial
                  issuance of the securities by the trust fund;

         o        solely as a result of the use of pre-funding, the weighted
                  average annual percentage interest rate for the mortgage loans
                  included in the related trust fund on the Closing Date and all
                  additional mortgage loans transferred to the related trust
                  fund after the Closing Date at the end of the Pre-Funding
                  Period must not be more than 100 basis points lower than the
                  rate for the mortgage loans which were transferred to the
                  trust fund on the Closing Date;

         o        either:

                  (1)      the characteristics of the additional mortgage loans
                           transferred to the related trust fund after the
                           Closing Date must be monitored by an insurer or other
                           credit support provider which is independent of the
                           depositor; or

                  (2)      an independent accountant retained by the depositor
                           must provide the depositor with a letter (with copies
                           provided to the Exemption Rating Agency rating the
                           securities, the Underwriter and the trustee) stating
                           whether or not the characteristics of the additional
                           mortgage loans transferred to the related trust fund
                           after the Closing Date conform to the characteristics
                           described in the prospectus or prospectus supplement
                           and/or agreement. In preparing the letter, the
                           independent accountant must use the same type of
                           procedures as were applicable to the mortgage loans
                           which were transferred to the trust fund as of the
                           Closing Date;

         o        the Pre-Funding Period must end no later than three months or
                  90 days after the Closing Date or earlier in some
                  circumstances if the pre-funding accounts falls below the
                  minimum level specified in the Agreement or an event of
                  default occurs;

         o        amounts transferred to any pre-funding accounts and/or
                  capitalized interest account used in connection with the
                  pre-funding may be invested only in investments which are
                  permitted by the Exemption Rating Agencies rating the
                  securities and must:

                  (1)      be direct obligations of, or obligations fully
                           guaranteed as to timely payment of principal and
                           interest by, the United States or any agency or
                           instrumentality thereof (provided that the
                           obligations are backed by the full faith and credit
                           of the United States); or

                  (2)      have been rated (or the obligor has been rated) in
                           one of the three highest generic rating categories by
                           one of the Exemption Rating Agencies ("ERISA
                           Permitted Investments");

         o        the prospectus or prospectus supplement must describe the
                  duration of the Pre-Funding Period;

                                    - 151 -


         o        the trustee (or any agent with which the trustee contracts to
                  provide trust services) must be a substantial financial
                  institution or trust company experienced in trust activities
                  and familiar with its duties, responsibilities and liabilities
                  with ERISA. The trustee, as legal owner of the trust fund,
                  must enforce all the rights created in favor of
                  securityholders of the trust fund, including employee benefit
                  plans subject to ERISA.

         REVOLVING POOL FEATURES.

         The Exemption only covers certificates backed by a "fixed" pool of
loans which requires that all the loans must be transferred to the trust fund or
identified at closing (or transferred within the Pre-Funding Period, if
pre-funding meeting the conditions described above is used). Accordingly,
certificates issued by trust funds which feature revolving pools of assets will
not be eligible for a purchase by Plans. However, securities which are notes
backed by revolving pools of assets may be eligible for purchase by Plans
pursuant to certain other prohibited transaction exemptions. See discussion
below in "ERISA Considerations Relating to Notes."

OTHER EXEMPTIONS

         Insurance companies contemplating the investment of general account
assets in the securities are encouraged to consult with their legal advisors
with respect to the applicability of Section 401(c) of ERISA.

ERISA CONSIDERATIONS RELATING TO NOTES

         Under the DOL Regulations, the assets of the trust fund would be
treated as "plan assets" of a Plan for the purposes of ERISA and the Code only
if the Plan acquires an "equity interest" in the trust fund and none of the
exceptions contained in the DOL Regulations is applicable. An equity interest is
defined under the DOL Regulations as an interest other than an instrument which
is treated as indebtedness under applicable local law and which has no
substantial equity features. Assuming that the notes are treated as indebtedness
without substantial equity features for purposes of the DOL Regulations, then
such notes will be eligible for purchase by Plans. However, without regard to
whether the notes are treated as an "equity interest" for such purposes, the
acquisition or holding of notes by or on behalf of a Plan could be considered to
give rise to a prohibited transaction if the trust fund or any of its affiliates
is or becomes a party in interest or disqualified person with respect to such
Plan, or in the event that a note is purchased in the secondary market and such
purchase constitutes a sale or exchange between a Plan and a party in interest
or disqualified person with respect to such Plan. There can be no assurance that
the trust fund or any of its affiliates will not be or become a party in
interest or a disqualified person with respect to a Plan that acquires notes.

         The Exemption permits trust funds which are grantor trusts,
owner-trusts, REMICs or FASITs, to issue notes, as well as certificates,
provided a legal opinion is received to the effect that the noteholders have a
perfected security interest in the trust fund's assets. The exemptive relief
provided under the Exemption for any prohibited transactions which could be
caused as a result of the operation, management or servicing of the trust fund
and its assets would not be



                                    - 152 -


necessary with respect to notes with no substantial equity features which are
issued as obligations of the trust fund. Nevertheless, because other prohibited
transactions might be involved, the Exemption would provide prohibited
transaction exemptive relief, provided that the same conditions of the Exemption
described above relating to certificates are met with respect to the notes. The
same limitations of such exemptive relief relating to acquisitions of
certificates by fiduciaries with respect to Excluded Plans would also be
applicable to the notes as described herein.

         In the event that the Exemption is not applicable to the notes, one or
more other prohibited transactions exemptions may be available to Plans
purchasing or transferring the notes depending in part upon the type of Plan
fiduciary making the decision to acquire the notes and the circumstances under
which such decision is made. These exemptions include, but are not limited to,
Prohibited Transaction Class Exemption 90-1 (regarding investments by insurance
company pooled separate accounts), Prohibited Transaction Class Exemption 91-38
(regarding investments by bank collective investments funds), PTCE 84-14
(regarding transactions effected by "qualified professional asset managers"),
PTCE 95-60 (regarding investments by insurance company general accounts) and
PTCE 96-23 (regarding transactions effected by "in-house asset managers")
(collectively, the "Investor-Based Exemptions"). However, even if the conditions
specified in these Investor-Based Exemptions are met, the scope of the relief
provided under such Exemptions might or might not cover all acts which might be
construed as prohibited transactions.

         In the event that the Exemption is not applicable to the notes, there
can be no assurance that any class of notes will be treated as indebtedness
without substantial equity features for purposes of the DOL Regulations. There
is increased uncertainty regarding the characterization of debt instruments that
do not carry an investment grade rating. Consequently, in the event of a
withdrawal or downgrade to below investment grade of the rating of a class of
notes, the subsequent transfer of such notes or any interest therein to a Plan
trustee or other person acting on behalf of a Plan, or using Plan Assets to
effect such transfer, will be restricted. Unless otherwise stated in the related
prospectus supplement, by acquiring a note, each purchaser will be deemed to
represent that either (1) it is not acquiring the note with Plan Assets; or (2)
(A) either (i) none of the issuing entity, the depositor any underwriter, the
trustee, the master servicer, any other servicer or any of their affiliates is a
party in interest with respect to such purchaser that is an ERISA plan or (ii)
PTCE 90-1, PTCE 91-38, PTCE 84-14, PTCE 95-60, PTCE 96-23 or some other
prohibited transaction exemption is applicable to the acquisition and holding of
the note by such purchaser and (B) the notes are rated investment grade or
better and such person believes that the notes are properly treated as
indebtedness without substantial equity features for purposes of the DOL
Regulations, and agrees to so treat the notes. Alternatively, regardless of the
rating of the notes, such person may provide the trustee with an opinion of
counsel, which opinion of counsel will not be at the expense of the issuing
entity, the depositor, the trustee, the master servicer or any other servicer,
which opines that the purchase, holding and transfer of such note or interest
therein is permissible under applicable law, will not constitute or result in a
non-exempt prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the issuing entity, the depositor, the trustee, the master
servicer or any other servicer to any obligation in addition to those undertaken
in the indenture.

                                    - 153 -


         EACH PROSPECTUS SUPPLEMENT WILL CONTAIN INFORMATION CONCERNING
CONSIDERATIONS RELATING TO ERISA AND THE CODE THAT ARE APPLICABLE TO THE RELATED
SECURITIES. BEFORE PURCHASING SECURITIES IN RELIANCE ON THE EXEMPTION, THE
INVESTOR-BASED EXEMPTIONS OR ANY OTHER EXEMPTION, A FIDUCIARY OF A PLAN SHOULD
ITSELF CONFIRM THAT REQUIREMENTS SET FORTH IN SUCH EXEMPTION WOULD BE SATISFIED.

         ANY PLAN INVESTOR WHO PROPOSES TO USE "PLAN ASSETS" OF ANY PLAN TO
PURCHASE SECURITIES OF ANY SERIES OR CLASS ARE ENCOURAGED TO CONSULT WITH ITS
COUNSEL WITH RESPECT TO THE POTENTIAL CONSEQUENCES UNDER ERISA AND SECTION 4975
OF THE CODE OF THE ACQUISITION AND OWNERSHIP OF SUCH SECURITIES.

CALLABLE SECURITIES

         With respect to classes of securities which were eligible for exemptive
relief under the Exemption and were issued as a Callable Class, the exercise of
the Call would be covered under the Exemption. However, with respect to classes
of exchangeable securities and Callable Classes which were not eligible for
exemptive relief under the Exemption when purchased, the exchange, purchase or
sale of such securities pursuant to the exercise of exchange rights or call
rights may give rise to prohibited transactions if a Plan and a party in
interest with respect to such Plan are involved in the transaction. However, one
or more Investor-Based Exemptions discussed above may be applicable to these
transactions.

TAX EXEMPT INVESTORS

         A Plan that is exempt from federal income taxation pursuant to Section
501 of the Code nonetheless will be subject to federal income taxation to the
extent that its income is "unrelated business taxable income" within the meaning
of Section 512 of the Code. All "excess inclusion" of a REMIC allocated to a
REMIC Residual Certificate and held by such an investor will be considered
"unrelated business taxable income" and thus will be subject to federal income
tax. See "Federal Income Tax Consequences--Taxation of Owners of REMIC Residual
Certificates--Excess Inclusions."

CONSULTATION WITH COUNSEL

         There can be no assurance that the Exemptions or any other DOL
exemption will apply with respect to any particular Plan that acquires the
securities or, even if all the conditions specified therein were satisfied, that
any such exemption would apply to transactions involving the trust fund.
Prospective Plan investors are encouraged to consult with their legal counsel
concerning the impact of ERISA and the Code and the potential consequences to
their specific circumstances prior to making an investment in the securities.
Neither the depositor, the trustees, the master servicer nor any of their
respective affiliates will make any representation to the effect that the
securities satisfy all legal requirements with respect to the investment therein
by Plans



                                    - 154 -


generally or any particular Plan or to the effect that the securities are an
appropriate investment for Plans generally or any particular Plan.

         BEFORE PURCHASING AN OFFERED SECURITY IN RELIANCE ON THE EXEMPTION, OR
AN INVESTOR-BASED EXEMPTION OR ANY OTHER EXEMPTION, A FIDUCIARY OF A PLAN OR
OTHER PLAN ASSET INVESTOR SHOULD ITSELF CONFIRM THAT (A) ALL THE SPECIFIC AND
GENERAL CONDITIONS SET FORTH IN THE EXEMPTION, AN INVESTOR-BASED EXEMPTION OR
OTHER EXEMPTION, WOULD BE SATISFIED AND (B) IN THE CASE OF A SECURITY PURCHASED
UNDER THE EXEMPTION, THE SECURITY CONSTITUTES A "SECURITY" FOR PURPOSES OF THE
EXEMPTION. IN ADDITION TO MAKING ITS OWN DETERMINATION AS TO THE AVAILABILITY OF
THE EXEMPTIVE RELIEF PROVIDED IN THE EXEMPTION, AND INVESTOR-BASED EXEMPTION OR
OTHER EXEMPTION, THE PLAN FIDUCIARY SHOULD CONSIDER ITS GENERAL FIDUCIARY
OBLIGATIONS UNDER ERISA IN DETERMINING WHETHER TO PURCHASE THE SECURITIES ON
BEHALF OF A PLAN.

         A governmental plan as defined in Section 3(32) of ERISA is not subject
to ERISA, or Code Section 4975. However, such governmental plan may be subject
to federal, state and local law, which is, to a material extent, similar to the
provisions of ERISA or a Code Section 4975. A fiduciary of a governmental plan
should make its own determination as to the propriety of such investment under
applicable fiduciary or other investment standards, and the need for the
availability of any exemptive relief under any similar law.

                            LEGAL INVESTMENT MATTERS

         Each class of certificates offered by this prospectus and by the
related prospectus supplement will be rated at the date of issuance in one of
the four highest rating categories by at least one Rating Agency. If so
specified in the related prospectus supplement, each such class that is rated in
one of the two highest rating categories by at least one Rating Agency will
constitute "mortgage related securities" for purposes of SMMEA, and, as such,
will be legal investments for persons, trusts, corporations, partnerships,
associations, business trusts and business entities (including depository
institutions, life insurance companies and pension funds) created pursuant to or
existing under the laws of the United States or of any State whose authorized
investments are subject to state regulation to the same extent that, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any agency or instrumentality thereof constitute legal
investments for the entities. Under SMMEA, if a State enacted legislation on or
prior to October 3, 1991 specifically limiting the legal investment authority of
any such entities with respect to "mortgage related securities," such securities
will constitute legal investments for entities subject to the legislation only
to the extent provided therein. Some States have enacted legislation which
overrides the preemption provisions of SMMEA. SMMEA provides, however, that in
no event will the enactment of any such legislation affect the validity of any
contractual commitment to purchase, hold or invest in "mortgage related
securities," or require the sale or other disposition of the securities, so long
as the contractual commitment was made or the securities acquired prior to the
enactment of the legislation.

         SMMEA also amended the legal investment authority of
federally-chartered depository institutions as follows: federal savings and loan
associations and federal savings banks may invest in, sell or otherwise deal
with "mortgage related securities" without limitation as to the percentage of
their assets represented thereby, federal credit unions may invest in the
securities,



                                    - 155 -


and national banks may purchase the securities for their own account without
regard to the limitations generally applicable to investment securities set
forth in 12 U.S.C. 24 (Seventh), subject in each case to such regulations as the
applicable federal regulatory authority may prescribe.

         The Federal Financial Institutions Examination Council has issued a
supervisory policy statement applicable to all depository institutions, setting
forth guidelines for and significant restrictions on investments in "high-risk
mortgage securities." The policy statement has been adopted by the Federal
Reserve Board, the Office of the Comptroller of the Currency, the FDIC and the
OTS with an effective date of February 10, 1992. The policy statement generally
indicates that a mortgage derivative product will be deemed to be high risk if
it exhibits greater price volatility than a standard fixed rate thirty-year
mortgage security. According to the policy statement, prior to purchase, a
depository institution will be required to determine whether a mortgage
derivative product that it is considering acquiring is high-risk, and if so that
the proposed acquisition would reduce the institution's overall interest rate
risk. Reliance on analysis and documentation obtained from a securities dealer
or other outside party without internal analysis by the institution would be
unacceptable. There can be no assurance as to which classes of offered
securities will be treated as high-risk under the policy statement.

         The predecessor to the OTS issued a bulletin, entitled, "Mortgage
Derivative Products and Mortgage Swaps", which is applicable to thrift
institutions regulated by the OTS. The bulletin established guidelines for the
investment by savings institutions in certain "high-risk" mortgage derivative
securities and limitations on the use of the securities by insolvent,
undercapitalized or otherwise "troubled" institutions. According to the
bulletin, such "high-risk" mortgage derivative securities include securities
having specified characteristics, which may include some classes of offered
securities. In addition, the National Credit Union Administration has issued
regulations governing federal credit union investments which prohibit investment
in specified types of securities, which may include some classes of offered
securities. Similar policy statements have been issued by regulators having
jurisdiction over other types of depository institutions.

         Any class of securities that is not rated in one of the two highest
rating categories by at least one Rating Agency, and any other class of
securities specified in the related prospectus supplement, will not constitute
"mortgage related securities" for purposes of SMMEA. Prospective investors in
these classes of securities, in particular, should consider the matters
discussed in the following paragraph.

         There may be other restrictions on the ability of investors either to
purchase some classes of offered securities or to purchase any class of offered
securities representing more than a specified percentage of the investors'
assets. The depositor will make no representations as to the proper
characterization of any class of offered securities for legal investment or
other purposes, or as to the ability of particular investors to purchase any
class of certificates under applicable legal investment restrictions. These
uncertainties may adversely affect the liquidity of any class of certificates.
Accordingly, all investors whose investment activities are subject to legal
investment laws and regulations, regulatory capital requirements or review by
regulatory authorities are encouraged to consult with their own legal advisors
in determining whether and to what extent the offered securities of any class
thereof constitute legal investments or are subject



                                    - 156 -


to investment, capital or other restrictions, and, if applicable, whether SMMEA
has been overridden in any jurisdiction relevant to the investor.

                                 USE OF PROCEEDS

         Substantially all of the net proceeds to be received from the sale of
certificates will be applied by the depositor to finance the purchase of, or to
repay short-term loans incurred to finance the purchase of, the mortgage loans
in the respective mortgage pools and to pay other expenses. The depositor
expects that it will make additional sales of securities similar to the offered
securities from time to time, but the timing and amount of any such additional
offerings will be dependent upon a number of factors, including the volume of
mortgage loans purchased by the depositor, prevailing interest rates,
availability of funds and general market conditions.

                             METHODS OF DISTRIBUTION

         The certificates offered by this prospectus and by the related
prospectus supplements will be offered in series through one or more of the
methods described below. The prospectus supplement prepared for each series will
describe the method of offering being utilized for that series and will state
the net proceeds to the depositor from the sale.

         As to any offering of securities, in addition to the method of
distribution as described in the prospectus supplement and this base prospectus,
the distribution of any class of the offered securities may be effected through
one or more resecuritization transactions, in accordance with Rule 190(b).

         The depositor intends that offered securities will be offered through
the following methods from time to time and that offerings may be made
concurrently through more than one of these methods or that an offering of the
offered securities of a particular series may be made through a combination of
two or more of these methods. The methods are as follows:

         o        By negotiated firm commitment or best efforts underwriting and
                  public re-offering by underwriters;

         o        By placements by the depositor with institutional investors
                  through dealers; and

         o        By direct placements by the depositor with institutional
                  investors.

         If underwriters are used in a sale of any offered securities (other
than in connection with an underwriting on a best efforts basis), the
certificates will be acquired by the underwriters for their own account and may
be resold from time to time in one or more transactions, including negotiated
transactions, at fixed public offering prices or at varying prices to be
determined at the time of sale or at the time of commitment therefor. The
underwriters may be broker-dealers affiliated with the depositor whose
identities and relationships to the depositor will be as set forth in the
related prospectus supplement. The managing underwriter or underwriters with
respect to the offer and sale of the offered securities of a particular series
will be set forth on the cover of the prospectus supplement relating to the
series and the members of the underwriting syndicate, if any, will be named in
the prospectus supplement.

                                    - 157 -


         In connection with the sale of the offered securities, underwriters may
receive compensation from the depositor or from purchasers of the certificates
in the form of discounts, concessions or commissions. Underwriters and dealers
participating in the distribution of the offered securities may be deemed to be
underwriters in connection with the certificates, and any discounts or
commissions received by them from the depositor and any profit on the resale of
offered securities by them may be deemed to be underwriting discounts and
commissions under the Securities Act.

         It is anticipated that the underwriting agreement pertaining to the
sale of offered securities of any series will provide that the obligations of
the underwriters will be subject to conditions precedent, that the underwriters
will be obligated to purchase all such certificates if any are purchased (other
than in connection with an underwriting on a best efforts basis) and that, in
limited circumstances, the depositor will indemnify the several underwriters and
the underwriters will indemnify the depositor against specified civil
liabilities, including liabilities under the Securities Act or will contribute
to payments required to be made in respect thereof.

         The prospectus supplement with respect to any series offered by
placements through dealers will contain information regarding the nature of the
offering and any agreements to be entered into between the depositor and
purchasers of offered securities of the series.

         The depositor anticipates that the certificates offered by this
prospectus and the prospectus supplement will be sold primarily to institutional
investors or sophisticated non-institutional investors. Purchasers of offered
securities, including dealers, may, depending on the facts and circumstances of
the purchases, be deemed to be "underwriters" within the meaning of the
Securities Act in connection with reoffers and sales by them of the
certificates. Holders of offered securities are encouraged to consult with their
legal advisors in this regard prior to any such reoffer or sale.

                                  LEGAL MATTERS

         Legal matters in connection with the securities of each series,
including both federal income tax matters and the legality of the securities
being offered, will be passed upon for the depositor by Thacher Proffitt & Wood
LLP, New York, New York. With respect to each series of securities, a copy of
this opinion will be filed with the Commission on Form 8-K within 15 days after
the Closing Date.

                              FINANCIAL INFORMATION

         With respect to each series of certificates, a new trust fund will be
formed, and no trust fund will engage in any business activities or have any
assets or obligations prior to the issuance of the related series of
certificates. Accordingly, no financial statements with respect to any trust
fund related to a series of certificates will be included in this prospectus or
in the related prospectus supplement.

         With respect to each series of notes, where the issuing entity is a
statutory business trust or a limited liability company, financial statements
will be filed as required by the Exchange Act. Each such issuing entity will
suspend filing the reports if and when the reports are no longer required under
the Exchange Act.


                                    - 158 -


                                     RATING

         It is a condition to the issuance of any class of offered securities
that they shall have been rated not lower than investment grade, that is, in one
of the four highest rating categories, by at least one Rating Agency.

         Ratings on mortgage pass-through certificates and mortgage-backed notes
address the likelihood of receipt by the holders thereof of all collections on
the underlying mortgage assets to which the holders are entitled. These ratings
address the structural, legal and issuing entity-related aspects associated with
the certificates and notes, the nature of the underlying mortgage assets and the
credit quality of the guarantor, if any. Ratings on mortgage pass-through
certificates and mortgage-backed notes do not represent any assessment of the
likelihood of principal prepayments by borrowers or of the degree by which the
prepayments might differ from those originally anticipated. As a result,
securityholders might suffer a lower than anticipated yield, and, in addition,
holders of stripped interest securities in extreme cases might fail to recoup
their initial investments.

         A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning rating organization.

                    INCORPORATION OF INFORMATION BY REFERENCE

         There are incorporated in this prospectus and in the related prospectus
supplement by reference all documents and reports filed or caused to be filed by
the depositor with respect to a trust fund pursuant to Sections 13(a), 13(c), 14
or 15(d) of the Exchange Act, prior to the termination of the offering of the
offered securities of the related series. All documents subsequently filed by
the depositor pursuant to Sections 13(a) or 15(d) of the Exchange Act in respect
of any offering prior to the termination of the offering of the offered
securities shall also be deemed incorporated by reference into this prospectus
and the related prospectus supplement.

         The depositor will provide or cause to be provided without charge to
each person to whom this prospectus is delivered in connection with the offering
of one or more classes of offered securities, upon written or oral request of
the person, a copy of any or all the reports incorporated in this prospectus by
reference, in each case to the extent the reports relate to one or more of such
classes of the offered securities, other than the exhibits to the documents,
unless the exhibits are specifically incorporated by reference in the documents.
Requests should be directed in writing to Impac Secured Assets Corp., 1401 Dove
Street, Newport Beach, California 92660, or by telephone at (949) 475-3600. The
depositor has determined that its financial statements will not be material to
the offering of any offered securities.

FOR ADDITIONAL INFORMATION REGARDING THE MORTGAGE LOANS, SEE "THE MORTGAGE POOL"
IN THIS PROSPECTUS SUPPLEMENT.

REMOVAL AND SUBSTITUTION OF A MORTGAGE LOAN

The trustee will acknowledge the sale, transfer and assignment of the trust fund
to it by the depositor and receipt of, subject to further review and any
exceptions, the mortgage loans. If the trustee finds that any mortgage loan is
defective on its face due to a breach of the representations and warranties with
respect to that loan made in the transaction agreements, the trustee shall
promptly notify the sponsor of such defect. The sponsor must then correct or
cure any such defect within 90 days from the date of notice from the trustee of
the defect and if the sponsor fails to correct or cure such defect within such
period and such defect materially and adversely affects the interests of the
certificateholders in the related mortgage loan, the sponsor will, in accordance
with the terms of the pooling and servicing agreement, within 90 days of the
date of notice, provide the trustee with a substitute mortgage loan (if within
two years of the closing date); provided that, if such defect would cause the
mortgage loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Internal Revenue Code, any such cure or substitution must
occur within 90 days from the date such breach was discovered.

THE CERTIFICATES

OFFERED CERTIFICATES. The offered certificates will have the characteristics
shown in the table above in this prospectus supplement. The pass-through rates
on each class of offered certificates (other


                                      S-6


than the Class XS Certificates) are fixed and shown in the table above.

The pass-through rate on the Class XS Certificates is variable. Investors in the
Class XS Certificates should fully consider the risk that a rapid rate of
prepayments on the mortgage loans that have net mortgage rates higher than ____%
could result in the failure of these investors to fully recover their
investments.

[The Class PO Certificates are not entitled to interest payments and their yield
is extremely sensitive to the rate of prepayments on the mortgage loans.]

CREDIT ENHANCEMENT

The credit enhancement provided for the benefit of the holders of the offered
certificates consists of subordination as described below and under "Description
of the Certificates--Allocation of Losses; Subordination" in this prospectus
supplement.

On any distribution date, realized losses (other than Excess Losses) will be
allocated first, to the Class B-6 Certificates; second, to the Class B-5
Certificates; third, to the Class B-4 Certificates; fourth, to the Class B-3
Certificates; fifth, to the Class B-2 Certificates; and sixth, to the Class B-1
Certificates, in each case until the certificates principal balance of such
class has been reduced to zero.

In addition, such realized losses will be allocated on any distribution date
among the Class A Certificates on a pro rata basis. Excess losses will be
allocated on any distribution date among all the certificates (other than the
Class XS Certificates) on a pro rata basis.

 [Additional information with respect to credit enhancement providers, required
pursuant to Item 1114(b) of Regulation AB, will be provided if applicable.]

[Any third parties providing credit support for 10% or more of the pool assets

to the trust on the closing date. Payments under the derivative contracts will
be made pursuant to the formulas described below and in this prospectus
supplement.

On the closing date, either the sponsor will assign to the depositor, and the
depositor will assign to the issuing entity for the benefit of the certificates,
its rights under the derivative contracts, or the sponsor will cause the issuing
entity to enter into the derivative contracts with the derivative counterparty.
The derivative contracts will contain a swap agreement fixed rate and provide
for the calculation of One-Month LIBOR. The derivative contracts consists of
___________ swap agreement, where net payments will be made (a) to the issuing
entity, if One-Month LIBOR exceeds the swap agreement fixed rate, and (b) to the
derivative counterparty, to the extent such swap agreement fixed rate exceeds
One-Month LIBOR

[The derivatives counterparties will be _____________________________.]

[Additional financial information regarding derivatives counterparties will be
provided, as required pursuant to Item 1115 of Regulation AB, if applicable.]

SEE "DESCRIPTION OF THE CERTIFICATES--THE DERIVATIVE CONTRACTS" IN THIS
PROSPECTUS SUPPLEMENT.


ADVANCES

The master servicer will make cash advances with respect to delinquent payments
of


                                      S-7



scheduled interest and principal on the mortgage loans for which it acts as
master servicer, in general, to the extent that the master servicer reasonably
believes that such cash advances can be repaid from future payments on the
related mortgage loans. If the master servicer fails to make any required
advances, the trustee may be obligated to do so, as described in this prospectus
supplement. These cash advances are only intended to maintain a regular flow of
scheduled interest and principal payments on the certificates and are not
intended to guarantee or insure against losses.

SERVICING FEE

With respect to each mortgage loan, the amount of the annual master servicing
fee that shall be paid to the master servicer is for a period of one full month,
equal to one-twelfth of the product of (a) [___]% and (b) the stated principal
balance of the mortgage loan for the calendar month preceding the month in which
the payment is due. Such fee shall be payable monthly, computed on the basis of
the same principal amount and period respecting which any related interest
payment on a mortgage loan is computed. The obligation to pay the master
servicing fee is limited to, and the master servicing fee is payable from the
interest portion of such monthly payments collected.

OPTIONAL TERMINATION

At its option, the master servicer may purchase all of the mortgage loans,
together with any properties in respect thereof acquired on behalf of the trust,
and thereby effect termination and early retirement of the certificates, after
the aggregate principal balance of the mortgage loans (and properties acquired
in respect thereof) remaining in the trust has been reduced to less than [10%]
of the aggregate principal balance of the mortgage loans as of __________ __,
____. See "Pooling and Servicing Agreement--Termination" in this prospectus
supplement.

[A summary of other events that can trigger liquidation or amortization of the
asset pool or otherwise would alter the transaction structure or flow funds,
required pursuant to Item 1103(a)(3)(viii) of Regulation AB, will be provided if
applicable.]

FEDERAL INCOME TAX CONSEQUENCES

An election will be made to treat the trust as a real estate mortgage investment
conduit for federal income tax purposes.

SEE "FEDERAL INCOME TAX CONSEQUENCES" IN THIS PROSPECTUS SUPPLEMENT.

                                  RISK FACTORS

         You should carefully consider, among other things, the following
factors in connection with the purchase of the offered certificates:

         [APPROPRIATE RISK FACTORS FROM THE FOLLOWING LIST AS NECESSARY]

THE OFFERED CERTIFICATES WILL HAVE LIMITED LIQUIDITY, SO YOU MAY BE UNABLE TO
SELL YOUR SECURITIES OR MAY BE FORCED TO SELL THEM AT A DISCOUNT FROM THEIR FAIR
MARKET VALUE

         There can be no assurance that a secondary market for the offered
certificates of any series will develop or, if it does develop, that it will
provide offered certificateholders with liquidity of investment or that it will
continue for the life of the offered certificates of any series. The prospectus
supplement for any series of offered certificates may indicate that an
underwriter specified therein intends to establish a secondary market in the
offered certificates, however no underwriter will be obligated to do so. As a
result, any resale prices that may be available for any offered certificate in
any market that may develop may be at a discount from the initial offering price
or the fair market value thereof. The offered certificates will not be listed on
any securities exchange.

CREDIT ENHANCEMENT IS LIMITED; THE FAILURE OF CREDIT ENHANCEMENT TO COVER LOSSES
ON THE TRUST FUND ASSETS MAY RESULT IN LOSSES ALLOCATED TO THE OFFERED
CERTIFICATES

         With respect to the offered certificates, credit enhancement will be
provided in limited amounts to cover various types of losses on the underlying
mortgage loans. Credit enhancement will be provided in one or more of the forms
referred to in this prospectus supplement, including: subordination of any
subordinate securities of the same series; a financial guaranty insurance
policy; a letter of credit; a purchase obligation; a mortgage pool insurance
policy; a special hazard insurance policy; overcollateralization; a reserve
fund; a cash flow agreement; or any combination thereof. SEE "SUBORDINATION" AND
"DESCRIPTION OF CREDIT ENHANCEMENT" IN THE PROSPECTUS. Regardless of the form of
credit enhancement provided, the amount of coverage will be limited in amount
and in most cases will be subject to periodic reduction in accordance with a
schedule or formula. Furthermore, credit enhancement may provide only very
limited coverage as to some types of losses or risks, and may provide no
coverage as to other types of losses or risks. In the event losses exceed the
amount of coverage provided by any credit enhancement or losses of a type not
covered by any credit enhancement occur, they will be borne by the holders of
the related offered certificates in the order described in this prospectus
supplement. The depositor, the master servicer or other specified person will
generally be permitted to reduce, terminate or substitute all or a portion of
the credit enhancement for any series of offered certificates, if each
applicable rating agency indicates that the then-current rating(s) thereof will
not be adversely affected. The ratings of any series of offered certificates by
any applicable rating agencies may be lowered following the initial issuance
thereof as a result of the downgrading of the obligations of any applicable
credit support provider, or as a result of losses on the related mortgage loans
in excess of the levels contemplated by the rating agencies at the time of their
initial rating analysis. Neither the depositor, the master servicer nor any of
their respective affiliates will have any obligation to replace or supplement
any credit enhancement, or to take any other action to maintain any rating(s) of
any series of offered certificates. SEE "DESCRIPTION OF CREDIT ENHANCEMENT--
REDUCTION OR SUBSTITUTION OF CREDIT ENHANCEMENT" IN THE PROSPECTUS.


                                      S-11


THE RATINGS ON THE OFFERED CERTIFICATES ARE NOT A RECOMMENDATION TO BUY, SELL OR
HOLD THE OFFERED CERTIFICATES AND ARE SUBJECT TO WITHDRAWAL AT ANY TIME, WHICH
MAY RESULT IN LOSSES ON THE OFFERED CERTIFICATES.

         It is a condition to the issuance of the offered certificates that each
class of offered certificates be rated in one of the four highest rating
categories by a nationally recognized statistical rating agency. A security
rating is not a recommendation to buy, sell or hold securities and may be
subject to revision or withdrawal at any time. No person is obligated to
maintain the rating on any offered certificate, and, accordingly, there can be
no assurance that the ratings assigned to any offered certificate on the date on
which the offered certificates are initially issued will not be lowered or
withdrawn by a rating agency at any time thereafter. In the event any rating is
revised or withdrawn, the liquidity or the market value of the related offered
certificates may be adversely affected. SEE "RATINGS" IN THIS PROSPECTUS
SUPPLEMENT AND IN THE PROSPECTUS.

STATUTORY AND JUDICIAL LIMITATIONS ON FORECLOSURE PROCEDURES MAY DELAY RECOVERY
IN RESPECT OF THE MORTGAGED PROPERTY AND, IN SOME INSTANCES, LIMIT THE AMOUNT
THAT MAY BE RECOVERED BY THE FORECLOSING LENDER, RESULTING IN LOSSES ON THE
MORTGAGE LOANS THAT MIGHT BE ALLOCATED TO THE OFFERED CERTIFICATES.

         Foreclosure procedures may vary from state to state. Two primary
methods of foreclosing a mortgage instrument are judicial foreclosure, involving
court proceedings, and non-judicial foreclosure pursuant to a power of sale
granted in the mortgage instrument. A foreclosure action is subject to most of
the delays and expenses of other lawsuits if defenses are raised or
counterclaims are asserted. Delays may also result from difficulties in locating
necessary defendants. Non-judicial foreclosures may be subject to delays
resulting from state laws mandating the recording of notice of default and
notice of sale and, in some states, notice to any party having an interest of
record in the real property, including junior lienholders. Some states have
adopted "anti-deficiency" statutes that limit the ability of a lender to collect
the full amount owed on a loan if the property sells at foreclosure for less
than the full amount owed. In addition, United States courts have traditionally
imposed general equitable principles to limit the remedies available to lenders
in foreclosure actions that are perceived by the court as harsh or unfair. The
effect of these statutes and judicial principles may be to delay and/or reduce
distributions in respect of the offered certificates. SEE "LEGAL ASPECTS OF
MORTGAGE LOANS--FORECLOSURE ON MORTGAGE LOANS" IN THE PROSPECTUS.

THE VALUE OF THE MORTGAGE LOANS MAY BE AFFECTED BY, AMONG OTHER THINGS, A
DECLINE IN REAL ESTATE VALUES AND CHANGES IN THE BORROWERS' FINANCIAL CONDITION,
WHICH MAY RESULT IN LOSSES ON THE OFFERED CERTIFICATES.

         No assurance can be given that values of the mortgaged properties have
remained or will remain at their levels on the dates of origination of the
related mortgage loans. If the residential real estate market should experience
an overall decline in property values so that the outstanding balances of the
mortgage loans, and any secondary financing on the mortgaged properties, in a
particular mortgage pool become equal to or greater than the value of the
mortgaged properties, the actual rates of delinquencies, foreclosures and losses
could be higher than those now generally experienced in the mortgage lending
industry. In particular, mortgage loans with high loan-to-value ratios will be
affected by any decline in real estate values. Any decrease in the value of the
mortgage loans may result in the allocation of losses which are not covered by
credit enhancement to the offered certificates.


                                      S-12


THE MORTGAGE LOANS WERE UNDERWRITTEN TO NON-CONFORMING UNDERWRITING STANDARDS,
WHICH MAY RESULT IN LOSSES ON THE MORTGAGE LOANS ALLOCATED TO THE OFFERED
CERTIFICATES.

         Some mortgage loans may be underwritten in accordance with underwriting
standards which are primarily intended to provide single family mortgage loans
for non-conforming credits. A "non-conforming credit" means a mortgage loan
which is ineligible for purchase by Fannie Mae or Freddie Mac due to credit
characteristics that do not meet the Fannie Mae or Freddie Mac underwriting
guidelines, including mortgagors whose creditworthiness and repayment ability do
not satisfy these underwriting guidelines and mortgagors who may have a record
of credit write-offs, outstanding judgments, prior bankruptcies and other credit
items that do not satisfy these underwriting guidelines. Accordingly, mortgage
loans underwritten under the originators' non-conforming credit underwriting
standards are likely to experience rates of delinquency, foreclosure and loss
that are higher, and may be substantially higher, than mortgage loans originated
in accordance with the Fannie Mae or Freddie Mac underwriting guidelines. Any
resulting losses, to the extent not covered by credit enhancement, may affect
the yield to maturity of the offered certificates.

THE MORTGAGE LOANS HAVE VARIABLE PAYMENTS, WHICH MAY RESULT IN LOSSES WITH
RESPECT TO THESE MORTGAGE LOANS

         Some of the types of loans included in the mortgage pool may involve
additional uncertainties not present in traditional types of loans. In the case
of mortgage loans that are subject to negative amortization, due to the addition
to principal balance of deferred interest, the principal balances of these
mortgage loans could be increased to an amount equal to or in excess of the
value of the underlying mortgaged properties, thereby increasing the likelihood
of default. In the case of buydown loans, the increase in the monthly payment by
the mortgagor during and following the buydown period may result in an increased
risk of default on a buydown loan. Some of the mortgage loans provide for
escalating or variable payments by the mortgagor, as to which the mortgagor is
generally qualified on the basis of the initial payment amount. In some
instances, mortgagors may not be able to make their loan payments as payments
increase and thus the likelihood of default will increase.

         This is a consideration with respect to revolving credit loans, since
additional draws may be made by the mortgagor in the future up to the applicable
credit limit. Although revolving credit loans are generally subject to
provisions whereby the credit limit may be reduced as a result of a material
adverse change in the mortgagor's economic circumstances, the servicer or master
servicer generally will not monitor for these changes and may not become aware
of them until after the mortgagor has defaulted. Under extreme circumstances, a
mortgagor may draw his entire credit limit in response to personal financial
needs resulting from an adverse change in circumstances. For a series of offered
certificates backed by the trust balances of revolving credit loans, even though
the trust balance of a revolving credit loan will not increase as a result of
draws after the offered certificates are issued, the foregoing considerations
are relevant because the trust balance will share pro rata in any losses
incurred on a revolving credit loan.

         Any risks associated with the variable payments of the mortgage loans
may affect the yield to maturity of the offered certificates to the extent of
losses caused by these risks which are not covered by credit enhancement are
allocated to the offered certificates.

THE MORTGAGE LOANS ARE SECURED BY JUNIOR LIENS, WHICH MAY RESULT IN LOSSES WITH
RESPECT TO THESE MORTGAGE LOANS

         The mortgage loan are secured by second liens on the related mortgaged
properties. As to mortgage loans secured by second mortgages, the proceeds from
any liquidation, insurance or


                                      S-13


condemnation proceedings will be available to satisfy the outstanding balance of
these mortgage loans only to the extent that the claims of the senior mortgages
have been satisfied in full, including any related foreclosure costs. In
addition, the holder of a mortgage loan secured by a junior mortgage may not
foreclose on the mortgaged property unless it forecloses subject to the senior
mortgages, in which case it must either pay the entire amount due on the senior
mortgages to the senior mortgagees at or prior to the foreclosure sale or
undertake the obligation to make payments on the senior mortgages in the event
the mortgagor is in default. The trust fund will not have any source of funds to
satisfy the senior mortgages or make payments due to the senior mortgagees,
although the master servicer or subservicer may, at its option, advance these
amounts to the extent deemed recoverable and prudent. In the event that proceeds
from a foreclosure or similar sale of the related mortgaged property are
insufficient to satisfy all senior liens and the mortgage loan in the aggregate,
the trust fund, as the holder of the junior lien, and, accordingly, holders of
one or more classes of the offered certificates, to the extent not covered by
credit enhancement, are likely to (1) incur losses in jurisdictions in which a
deficiency judgment against the borrower is not available, and (2) incur losses
if any deficiency judgment obtained is not realized upon. In addition, the rate
of default of second mortgage loans may be greater than that of mortgage loans
secured by first liens on comparable properties.

THE MORTGAGE LOANS ARE CONCENTRATED IN THE STATE OF [NAME OF STATE], WHICH MAY
RESULT IN LOSSES WITH RESPECT TO THESE MORTGAGE LOANS

         Approximately ___% of the mortgage loans are in the state of [Name of
State.] Investors should note that some geographic regions of the United States
from time to time will experience weaker regional economic conditions and
housing markets, and, consequently, will experience higher rates of loss and
delinquency than will be experienced on mortgage loans generally. For example, a
region's economic condition and housing market may be directly, or indirectly,
adversely affected by natural disasters or civil disturbances such as
earthquakes, hurricanes, floods, eruptions or riots. The economic impact of any
of these types of events may also be felt in areas beyond the region immediately
affected by the disaster or disturbance. The mortgage loans securing the offered
certificates may be concentrated in these regions, and any concentration may
present risk considerations in addition to those generally present for similar
mortgage-backed securities without this concentration. Moreover, as described
below, any mortgage loan for which a breach of a representation or warranty
exists will remain in the related trust fund in the event that a seller is
unable, or disputes its obligation, to repurchase the mortgage loan and the
breach does not also constitute a breach of any representation made by any other
person. In this event, any resulting losses will be borne by the related form of
credit enhancement, to the extent available. Any risks associated with mortgage
loan concentration may affect the yield to maturity of the offered certificates
to the extent losses caused by these risks which are not covered by [credit
enhancement] are allocated to the offered certificates.

SOME OF THE MORTGAGE LOANS PROVIDE FOR BALLOON PAYMENTS AT MATURITY, WHICH MAY
RESULT IN A GREATER RISK OF LOSS WITH RESPECT TO THESE MORTGAGE LOANS

         Approximately ___% of the mortgage loans are balloon loans. These
mortgage loans will require substantial payments of principal and interest (that
is, balloon payments) at their stated maturity. Mortgage loans of this type
involve a greater degree of risk than self-amortizing loans because the ability
of a mortgagor to make a balloon payment typically will depend upon its ability
either to fully refinance the loan or to sell the related mortgaged property at
a price sufficient to permit the mortgagor to make the balloon payment. The
ability of a mortgagor to accomplish either of these goals will be affected by a
number of factors, including the value of the related mortgaged property, the
level of available mortgage rates at the time of sale or refinancing, the
mortgagor's equity in the related mortgaged property, prevailing general
economic conditions, the availability of credit for loans secured by comparable
real properties. Any risks associated with the balloon loans may affect the
yield to maturity of the offered


                                      S-14


certificates to the extent losses caused by these risks which are not covered by
credit enhancement are allocated to the offered certificates.

THE MORTGAGE LOANS MAY HAVE LIMITED RECOURSE TO THE RELATED BORROWER, WHICH MAY
RESULT IN LOSSES WITH RESPECT TO THESE MORTGAGE LOANS

Some or all of the mortgage loans included in the trust fund will be nonrecourse
loans or loans for which recourse may be restricted or unenforceable. As to
those mortgage loans, recourse in the event of mortgagor default will be limited
to the specific real property and other assets, if any, that were pledged to
secure the mortgage loan. However, even with respect to those mortgage loans
that provide for recourse against the mortgagor and its assets generally, there
can be no assurance that enforcement of the recourse provisions will be
practicable, or that the other assets of the mortgagor will be sufficient to
permit a recovery in respect of a defaulted mortgage loan in excess of the
liquidation value of the related mortgaged property. Any risks associated with
mortgage loans with no or limited recourse may affect the yield to maturity of
the offered certificates to the extent losses caused by these risks which are
not covered by credit enhancement are allocated to the offered certificates.

THE MORTGAGE LOANS HAVE HIGH COMBINED LOAN-TO-VALUE RATIOS, SO THAT THE RELATED
BORROWER HAS LITTLE OR NO EQUITY IN THE RELATED MORTGAGED PROPERTY, WHICH MAY
RESULT IN LOSSES WITH RESPECT TO THESE MORTGAGE LOANS

         The mortgage loans have combined loan-to-value ratios in excess of
100%. These mortgage loans were originated with a limited expectation of
recovering any amounts from the foreclosure of the related mortgaged property
and are underwritten with an emphasis on the creditworthiness of the related
borrower.

         If these mortgage loans go into foreclosure and are liquidated, there
may be no amounts recovered from the related mortgaged property because the
value of the collateral with respect to such mortgage loan may be less than the
amount of the mortgage loan. Unless the value of the property increases or the
principal amount of the related senior liens have been reduced so as to reduce
the current combined loan-to-value ratio of the related mortgage loan to below
100%, there may be no recovery from the related mortgaged property in the event
of foreclosure. Any resulting losses, to the extent not covered by credit
enhancement, may affect the yield to maturity of the offered certificates.

THE MORTGAGE LOANS PROVIDE FOR REVOLVING LINES OF CREDIT, WHICH MAY RESULT IN
LOSSES WITH RESPECT TO THESE MORTGAGE LOANS

With respect to revolving credit loans, except for some programs under which the
draw period is less than the full term thereof, required minimum monthly
payments are generally equal to or not significantly larger than the amount of
interest currently accruing on its balance, and therefore are not expected to
significantly amortize the outstanding principal amount of these mortgage loans
prior to maturity, which amount may include substantial draws recently made. As
a result, a borrower will generally be required to pay a substantial principal
amount at the maturity of a revolving credit loan. The ability of a borrower to
make this payment may be dependent on the ability to obtain refinancing of the
balance due on the revolving credit loan or to sell the related mortgaged
property. Furthermore, revolving credit loans generally have adjustable rates
that are subject to much higher maximum rates than typically apply to adjustable
rate first mortgage loans, and which may be as high as applicable usury
limitations. Mortgagors under revolving credit loans are generally qualified
based on an assumed payment which reflects either the initial interest rate or a
rate significantly lower than the maximum rate. An increase in the interest rate
over the mortgage rate applicable at the time the revolving credit loan was
originated may have an adverse effect on the ability of the mortgagor to pay the
required monthly payment. In addition,


                                      S-15


an increase in prevailing market interest rates may reduce the borrower's
ability to obtain refinancing and to pay the balance of a revolving credit loan
at its maturity.

VIOLATION OF VARIOUS FEDERAL, STATE AND LOCAL LAWS MAY RESULT IN LOSSES ON THE
MORTGAGE LOANS

         Applicable federal, state and local laws generally regulate interest
rates and other charges, require specific disclosures, prohibit unfair and
deceptive practices, regulate debt collection, and require licensing of the
originators of the mortgage loans and contracts. Depending on the provisions of
the applicable law and the specified facts and circumstances involved,
violations of those laws, policies and principles may limit the ability to
collect all or part of the principal of or interest on the mortgage loans and
may entitle the borrower to a refund of amounts previously paid. See "Legal
Aspects of Mortgage Loans" in the prospectus. To the extent these laws and
regulations result in losses on the mortgage loans, the yield to maturity of the
offered certificates, to the extent not covered by credit enhancement, may be
affected.

THE RATE OF PREPAYMENTS ON THE TRUST FUND ASSETS AND THE PURCHASE PRICE YOU PAID
FOR THE OFFERED CERTIFICATES MAY CAUSE YOUR YIELD TO BE LOWER THAN ANTICIPATED

The yield to maturity of the offered certificates of each series will depend on,
among other things, the rate and timing of principal payments (including
prepayments, liquidations due to defaults, and repurchases due to conversion of
adjustable rate loans to fixed interest rate loans or breaches of
representations and warranties), or draws (if applicable) on the related
mortgage loans and the price paid by offered certificateholders. The yield may
be adversely affected by a higher or lower than anticipated rate of prepayments
(or draws if applicable) on the related mortgage loans. The yield to maturity on
interest only offered certificates will be extremely sensitive to the rate of
prepayments (or draws if applicable) on the related mortgage loans. In addition,
the yield to maturity on other types of classes of offered certificates,
including offered certificates with an accrual feature, offered certificates
with an interest rate which fluctuates based on an index or inversely with an
index or other classes in a series including more than one class of offered
certificates, may be relatively more sensitive to the rate of prepayment (or
draws if applicable) on the related mortgage loans than other classes of offered
certificates. In addition, to the extent amounts in any funding account have not
been used to purchase additional mortgage loans, holders of the offered
certificates may receive an additional prepayment. Prepayments are influenced by
a number of factors, including prevailing mortgage market interest rates, local
and regional economic conditions and homeowner mobility. See "Yield
Considerations" and "Maturity and Prepayment Considerations" in the prospectus.

[THE RATE AND TIMING OF PRINCIPAL DISTRIBUTIONS ON THE OFFERED CERTIFICATES WILL
BE AFFECTED BY PREPAYMENT SPEEDS

         The rate and timing of distributions allocable to principal on the
Class A Certificates will depend, in general, on the rate and timing of
principal payments (including prepayments and collections upon defaults,
liquidations and repurchases) on the mortgage loans and the allocation thereof
to pay principal on these certificates as provided in this prospectus
supplement. The rate and timing of distributions allocable to principal on the
other classes of offered certificates, other than the Class XS Certificates,
will depend in general, on the rate and timing of principal payments (including
prepayments and collections upon defaults, liquidations and repurchases) on all
of the mortgage loans and the allocation thereof to pay principal on these
certificates as provided in this prospectus supplement. As is the case with
mortgage pass-through certificates generally, the offered certificates are
subject to substantial inherent cash-flow uncertainties because the mortgage
loans may be prepaid at any time. However, with respect to approximately _____%
of the mortgage loans, by aggregate principal balance as of ________ __, ____, a
prepayment may subject the related mortgagor to a prepayment charge, which may
act as a deterrent to prepayment of the mortgage loan. SEE "THE MORTGAGE POOL"
IN THIS PROSPECTUS SUPPLEMENT.


                                      S-16


         Generally, when prevailing interest rates are increasing, prepayment
rates on mortgage loans tend to decrease. A decrease in the prepayment rates on
the mortgage loans will result in a reduced rate of return of principal to
investors in the Class A Certificates at a time when reinvestment at higher
prevailing rates would be desirable. A decrease in the prepayment rates on all
of the mortgage loans will result in a reduced rate of return of principal to
investors in the other classes of offered certificates, other than the Class XS
Certificates, at a time when reinvestment at higher prevailing rates would be
desirable.

         Conversely, when prevailing interest rates are declining, prepayment
rates on mortgage loans tend to increase. An increase in the prepayment rates on
the mortgage loans will result in a greater rate of return of principal to
investors in the related Class A Certificates, at time when reinvestment at
comparable yields may not be possible. An increase in the prepayment rates on
all of the mortgage loans will result in a greater rate of return of principal
to investors in the other classes of offered certificates, other than the Class
XS Certificates, at a time when reinvestment at comparable yields may not be
possible.

         Prior to the distribution date in _______ ____, the subordinate
certificates will be entitled to receive distributions allocable to principal
based on a disproportionately small percentage of principal prepayments on the
mortgage loans, and the Class A Certificates will be entitled to receive
distributions allocable to principal based on a disproportionately large
percentage (which may be 100%) of principal prepayments on the mortgage loans.
To the extent that no principal prepayments or a disproportionately small
percentage of prepayments are distributed on the subordinate certificates, the
subordination afforded to the Class A Certificates, in the absence of losses
allocated to the Class A Certificates, will be increased.

         For further information regarding the effect of principal prepayments
on the weighted average lives of the offered certificates, see "Yield on the
Certificates" in this prospectus supplement, including the table entitled
"Percent of Initial Certificate Principal Balance Outstanding at the Following
Percentages of the Prepayment Assumption" in this prospectus supplement].

THE MORTGAGE LOANS MAY HAVE ENVIRONMENTAL RISKS, WHICH MAY RESULT IN INCREASED
LOSSES WITH RESPECT TO THESE MORTGAGE LOANS

         To the extent the master servicer for a mortgage loan acquires title to
any related mortgaged property with contaminated with or affected by hazardous
wastes or hazardous substances, these mortgage loans may incur losses. See
"Servicing of Mortgage Loans--Realization Upon or Sale of Defaulted Mortgage
Loans" and "Legal Aspects of Mortgage Loans--Environmental Legislation" in the
prospectus To the extent these environmental risks result in losses on the
mortgage loans, the yield to maturity of the offered certificates, to the extent
not covered by credit enhancement, may be affected.

THE [CLASS ___ CERTIFICATES] ARE ERISA-RESTRICTED, WHICH BY RESTRICTING THE
MARKET, MAY AFFECT THE LIQUIDITY OF THE OFFERED CERTIFICATES

         Generally, ERISA applies to investments made by employee benefit plans
and transactions involving the assets of plans. Due to the complexity of
regulations that govern these plans, prospective investors that are subject to
ERISA are urged to consult their own counsel regarding consequences under ERISA
of acquisition, ownership and disposition of the offered certificates of any
series. See "ERISA Considerations" in this prospectus supplement and in the
prospectus.


                                      S-17


[SOME MORTGAGE LOANS ARE DELINQUENT AS OF THE CUT-OFF DATE, WHICH MAY PRESENT A
GREATER RISK OF LOSS WITH RESPECT TO THESE MORTGAGE LOANS

         Approximately ____% of the mortgage loans, by aggregate principal
balance as of ________ __, ____, were thirty days or more but less than sixty
days delinquent in their monthly payments as of _______ __, ____. Approximately
____% of the mortgage loans, by aggregate principal balance as of ________ __,
____, were sixty days or more but less than ninety days delinquent in their
monthly payments as of the _________ __, ____. However, investors in the
mortgage loans should realize that approximately _____% of the mortgage loans,
by aggregate principal balance as of ________ __, ____, have a first payment
date occurring on or after _________ __, ____ and, therefore, these mortgage
loans could not have been delinquent as of ________ __, ____].

[THE YIELD TO MATURITY ON THE OFFERED CERTIFICATES WILL DEPEND ON A VARIETY OF
FACTORS

The yield to maturity on the offered certificates, particularly the Class XS
Certificates, will depend, in general, on:

o        the applicable purchase price; and

o        the rate and timing of principal payments (including prepayments and
         collections upon defaults, liquidations and repurchases) on the related
         mortgage loans and the allocation thereof to reduce the certificate
         principal balance or notional amount of the offered certificates, as
         well as other factors.

         The yield to investors on the offered certificates will be adversely
affected by any allocation thereto of interest shortfalls on the mortgage loans.

         In general, if the offered certificates, other than the Class XS
Certificates, are purchased at a premium and principal distributions occur at a
rate faster than anticipated at the time of purchase, the investor's actual
yield to maturity will be lower than that assumed at the time of purchase.
Conversely, if the offered certificates, other than the Class XS Certificates,
are purchased at a discount and principal distributions occur at a rate slower
than that anticipated at the time of purchase, the investor's actual yield to
maturity will be lower than that originally assumed.

         The proceeds to the depositor from the sale of the offered certificates
were determined based on a number of assumptions, including a prepayment
assumption of ____% of the standard prepayment assumption, and weighted average
lives corresponding thereto. No representation is made that the mortgage loans
will prepay at this rate or at any other rate, or that the mortgage loans will
prepay at the same rate. The yield assumptions for the offered certificates will
vary as determined at the time of sale. See "Yield on the Certificates" in this
prospectus supplement].

[THE MULTIPLE CLASS STRUCTURE OF THE OFFERED CERTIFICATES CAUSES THE YIELD OF
SOME CLASSES TO BE PARTICULARLY SENSITIVE TO CHANGES IN THE RATES OF PREPAYMENT
OF THE RELATED MORTGAGE LOANS AND OTHER FACTORS

CLASS XS CERTIFICATES: The Class XS Certificates will receive a portion of the
interest payments ONLY from mortgage loans that have net mortgage rates higher
than ____%. Therefore, the yield on the Class XS Certificates will be extremely
sensitive to the rate and timing of principal prepayments and defaults on the
mortgage loans. Investors in the Class XS Certificates should be aware that
mortgage loans with higher mortgage rates may prepay faster than mortgage loans
with lower mortgage rates. If the mortgage loans that have net mortgage rates
higher than ____% are prepaid at a rate faster than an investor assumed


                                      S-18


at the time of purchase, the yield to investors in the Class XS Certificates
will be adversely affected. Investors in the Class XS Certificates should fully
consider the risk that a rapid rate of prepayments on the mortgage loans that
have net mortgage rates higher than ____% could result in the failure of these
investors to fully recover their investments.

[CLASS PO CERTIFICATES: The Class PO Certificates are extremely sensitive to the
rate of prepayments on the mortgage loans. A slower than expected rate of
principal prepayments may result in a negative yield to investors in the Class
PO Certificates.]

SUBORDINATE CERTIFICATES: The weighted average lives of, and the yield to
maturity on, the Class B-1 Certificates, the Class B-2 Certificates and the
Class B-3 Certificates will be progressively more sensitive, in increasing order
of their numerical class designations, to losses due to defaults on the mortgage
loans (and the timing thereof), to the extent these losses are not covered by
subordinate certificates with a higher numerical class designation (including
covered by the Class B-4, Class B-5 and Class B-6 Certificates which are not
offered by this prospectus supplement). Furthermore, as described in this
prospectus supplement, the timing of receipt of principal and interest by any
class of subordinate certificates may be adversely affected by losses even if
this class does not ultimately bear this loss].

[THE RESIDUAL CERTIFICATES WILL RECEIVE LIMITED DISTRIBUTIONS OF PRINCIPAL AND
INTEREST AND MAY HAVE SIGNIFICANT TAX LIABILITIES

         Holders of the Class R Certificates are entitled to receive
distributions of principal and interest as described in this prospectus
supplement, but the holders of the Class R Certificates are not expected to
receive any distributions after the first distribution date. In addition,
holders of the Class R Certificates will have tax liabilities with respect to
their certificates during the early years of the term of the trust that
substantially exceed the principal and interest payable during or prior to that
time. See "Federal Income Tax Consequences" below and in the prospectus and
"Yield on the Certificates--Additional Yield Considerations Applicable Solely to
the Residual Certificates" in this prospectus supplement].

[VIOLATION OF VARIOUS FEDERAL, STATE AND LOCAL LAWS MAY RESULT IN LOSSES ON THE
MORTGAGE LOANS

         Applicable state and local laws generally regulate interest rates and
other charges, require specific disclosure, and require licensing of the
originator. In addition, other state and local laws, public policy and general
principles of equity relating to the protection of consumers, unfair and
deceptive practices and debt collection practices may apply to the origination,
servicing and collection of the mortgage loans.

         The mortgage loans are also subject to federal laws, including:

o        the Federal Truth-in-Lending Act and Regulation Z promulgated
         thereunder, which require specific disclosures to the borrowers
         regarding the terms of the mortgage loans;

o        the Equal Credit Opportunity Act and Regulation B promulgated
         thereunder, which prohibit discrimination on the basis of age, race,
         color, sex, religion, marital status, national origin, receipt of
         public assistance or the exercise of any right under the Consumer
         Credit Protection Act, in the extension of credit; and

o        the Fair Credit Reporting Act, which regulates the use and reporting of
         information related to the borrower's credit experience.

         Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these federal or state laws,
policies and principles may limit the ability of the trust


                                      S-19


to collect all or part of the principal of or interest on the mortgage loans,
may entitle the borrower to a refund of amounts previously paid and, in
addition, could subject the originator to damages and administrative
enforcement.

         The originator will represent that as of the closing date, each
mortgage loan is in compliance with applicable federal and state laws and
regulations. In the event of a breach of this representation, it will be
obligated to cure the breach or repurchase or replace the affected mortgage loan
in the manner described in the prospectus].

FICO SCORES MENTIONED IN THIS PROSPECTUS SUPPLEMENT ARE NOT AN INDICATOR OF
FUTURE PERFORMANCE OF BORROWERS.

         Investors should be aware that FICO scores are based on past payment
history of the borrower. Investors should not rely on FICO scores as an
indicator of future borrower performance. See "The Mortgage Pools--FICO Scores"
in the base prospectus.

                                THE MORTGAGE POOL

GENERAL

         References to percentages of the mortgage loans unless otherwise noted
are calculated based on the aggregate principal balance of the mortgage loans as
of the Cut-off Date.

         The mortgage pool will consist of approximately _____ conventional,
one- to four-family, [fixed-rate,] fully-amortizing mortgage loans secured by
first liens on mortgaged properties and having an aggregate principal balance as
of the Cut-off Date of approximately $___________, after application of
scheduled payments due on or before the Cut-off Date whether or not received and
subject to a permitted variance of plus or minus __%. The mortgage loans have
original terms to maturity of not greater than [30] years.

         The mortgage loans are secured by first mortgages or deeds of trust or
other similar security instruments creating first liens on one- to four-family
residential properties consisting of one- to four-family dwelling units,
townhouses, individual condominium units and individual units in planned unit
developments. The mortgage loans to be included in the mortgage pool will be
acquired by the depositor from the Originator.

         SEE "--UNDERWRITING STANDARDS; REPRESENTATIONS" IN THIS PROSPECTUS
SUPPLEMENT. THE ORIGINATOR WILL ACT AS THE MASTER SERVICER FOR THE MORTGAGE
LOANS ORIGINATED BY IT PURSUANT TO THE AGREEMENT.

         All of the mortgage loans have scheduled monthly payments due on the
Due Date. Each mortgage loan will contain a customary "due-on-sale" clause.

         Approximately _____% of the mortgage loans provide for payment by the
mortgagor of a prepayment charge in limited circumstances on prepayments.
Generally, these mortgage loans provide for payment of a prepayment charge on
partial or full prepayments made within one year, five years or other period as
provided in the related mortgage note from the date of origination of the
mortgage loan. The amount of the prepayment charge is as provided in the related
mortgage note, and the prepayment charge will generally apply if, in any
twelve-month period during the first year, five years or other period as
provided in the related mortgage note from the date of origination of the
mortgage loan, the Mortgagor prepays an aggregate amount exceeding __% of the
original principal balance of the mortgage loan. With respect to _____% of the
mortgage loans, the amount of the prepayment charge will generally be equal to
___ months' advance interest calculated on the basis of the mortgage rate in
effect at the time of the prepayment on the amount prepaid in excess of __% of
the original principal balance of the mortgage loan for a period of five years
and one year, respectively. The _____________ will be entitled to all prepayment
charges received on the mortgage loans, and these amounts will not be available
for distribution on the Certificates. The Master Servicer may, in its
discretion, waive the collection of any otherwise applicable prepayment charge
or reduce the amount thereof actually collected, and accordingly, there can be
no assurance that the prepayment charges will have any effect on the prepayment
performance of the mortgage loans.

         The average principal balance of the mortgage loans at origination was
approximately $______. No mortgage loan had a principal balance at origination
of greater than approximately $_______ or less than approximately $______. The
average principal balance of the mortgage loans as of the Cut-off Date was
approximately $______. No mortgage loan had a principal balance as of the
Cut-off Date of greater than approximately $_______ or less than approximately
$______.


                                      S-21


         As of the Cut-off Date, the mortgage loans had mortgage rates ranging
from approximately _____% per annum to approximately ______% per annum and the
weighted average mortgage rate was approximately _____% per annum. The weighted
average remaining term to stated maturity of the mortgage loans will be
approximately __ years and __ months as of the Cut-off Date. None of the
mortgage loans will have a first Due Date prior to ________ ____ or after
_________ ____, or will have a remaining term to maturity of less than __ years
and __ months or greater than __ years as of the Cut-off Date. The latest
maturity date of any mortgage loan is ________ ____.

         The weighted average loan-to-value ratio at origination of the mortgage
loans was approximately ______%. No loan-to-value ratio at origination was
greater than approximately _____% or less than approximately ____%.

         [As of the Cut-off date, not more than [ ]% of the mortgage loans were
more than 30 days delinquent in payments of principal and interest. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
one time during the twelve months preceding the cut-off date. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
two times during the twelve months preceding the Cut-off date. No more than
approximately [___]% of the mortgage loans have been more than 60 days
delinquent one time during the twelve months preceding the cut-off date. No more
than approximately [___]% of the mortgage loans have been more than 60 days
delinquent two times during the twelve months preceding the cut-off date.][No
mortgage loan will be more than 30 days delinquent as of the Cut-off Date.] A
loan is considered to be delinquent when a payment due on any due date remains
unpaid as of the close of business on the last business day immediately prior to
the next monthly due date. The determination as to whether a loan falls into
this category is made as of the close of business on the last business day of
each month.

         [If the trust contains mortgage securities, the mortgage securities
will be specifically identified by reference to the transaction(s) pursuant to
which such mortgage securities were issued, the percentage interest represented
by such mortgage securities and the characteristics of such mortgage securities
will be described in detail. In addition, the assets underlying the mortgage
securities will be described in detail.]

         The mortgage loans are expected to have the following characteristics
as of the Cut-off Date (the sum in any column may not equal the total indicated
due to rounding):

Residential Mortgage
Loans................



         Approximately [__]% of the mortgage loans have been originated
generally in accordance with credit, appraisal and underwriting standards
acceptable to [Name of Originator], which are referred to herein as the
Underwriting Standards. The Underwriting Standards are applied in accordance
with applicable federal and state laws and regulations.

UNDERWRITING STANDARDS

         All of the mortgage loans were originated by the Sponsor, generally in
accordance with the underwriting criteria specified in the prospectus, except as
described in this prospectus supplement.


                                      S-26


         ____% and ____% of the mortgage loans were underwritten pursuant to, or
in accordance with, the standards of Impac Funding's Progressive Series Program
or Progressive Express(TM) Program, respectively, each of which is described
below.

THE PROGRESSIVE SERIES PROGRAM

GENERAL.

The underwriting guidelines utilized in the Progressive Series Program, as
developed by Impac Funding, are intended to assess the borrower's ability and
willingness to repay the mortgage loan obligation and to assess the adequacy of
the mortgaged property as collateral for the mortgage loan. The Progressive
Series Program is designed to meet the needs of borrowers with excellent credit,
as well as those whose credit has been adversely affected. The Progressive
Series Program consists of six mortgage loan programs. Each program has
different credit criteria, reserve requirements, qualifying ratios and
Loan-to-Value Ratio restrictions. Series I is designed for credit history and
income requirements typical of "A" credit borrowers. In the event a borrower
does not fit the Series I criteria, the borrower's mortgage loan is placed into
either Series II, III, III+, IV, V or VI, depending on which series' mortgage
loan parameters meets the borrower's unique credit profile. Series II, III,
III+, IV, V or VI allow for less restrictive standards because of certain
compensating or offsetting factors such as a lower Loan-to-Value Ratio, verified
liquid assets, job stability, pride of ownership and, in the case of refinance
mortgage loans, length of time owning the mortgaged property. The philosophy of
the Progressive Series Program is that no single borrower characteristic should
automatically determine whether an application for a mortgage loan should be
approved or disapproved. Lending decisions are based on a risk analysis
assessment after the review of the entire mortgage loan file. Each mortgage loan
is individually underwritten with emphasis placed on the overall quality of the
mortgage loan. The Progressive Series I Program utilizes an average annual
salary to calculate the debt service-to- income ratio. Salaried borrowers are
evaluated based on a 12 month salary history, and self-employed and commission
borrowers are evaluated on a 24 month basis. The debt service-to-income ratio
for Series I borrowers is required to be within the range of 36% to 50%. The
Progressive Series II, III, III+, IV, V and VI Program borrowers are required to
have debt service-to-income ratios within the range of 45% to 60% calculated on
the basis of monthly income and depending on the Loan-to-Value Ratio of the
mortgage loan.

Under the Progressive Series Program, Impac Funding underwrites one- to
four-family mortgage loans with Loan-to-Value Ratios at origination of up to
95%, depending on, among other things, a borrower's credit history, repayment
ability and debt service-to-income ratio, as well as the type and use of the
mortgaged property. Second lien financing of the mortgaged properties may be
provided by lenders other than Impac Funding at origination; however, the
combined Loan-to-Value Ratio ("CLTV") generally may not exceed 95% for mortgage
loan amounts up to $400,000 and 90% for mortgage loan amounts above $400,000. In
certain circumstances, Impac Funding may allow second lien financing with CLTVs
of up to 100%. The mortgage loans in the Progressive Series Program generally
bear rates of interest that are greater than those which are originated in
accordance with FHLMC and FNMA standards. In general, the maximum amount for
mortgage loans originated under the Progressive Series Program is $750,000;
however, Impac Funding may approve mortgage loans in excess of such amount on a
case-by-case basis.

         All of the mortgage loans originated under the Progressive Series I, II
and III Programs are underwritten either by employees of Impac Funding or by
contracted mortgage insurance companies or delegated conduit sellers. Generally
all of the mortgage loans originated under the Series III+, IV, V and VI
Programs are underwritten by employees of Impac Funding. Substantially all of
the Series I Program mortgage loans and all of the Series II and III Program
mortgage loans with Loan-to-Value Ratios at origination in excess of 80% are
insured by a Primary Insurance Policy. None of the Series III+ Program Mortgage
Loans with Loan-to- Value Ratios at origination in excess of 80% will be insured
by a Primary Insurance Policy. In general, all Series IV, V and VI Program
Mortgage Loans have Loan-to-Value Ratios at origination which are less than or
equal to 85% and do not require a Primary


                                      S-27


Insurance Policy. Impac Funding receives verbal verification from Impac
Funding's conduit seller of employment prior to funding or acquiring each
Progressive Series Program mortgage loan.

FULL/ALTERNATIVE DOCUMENTATION AND REDUCED DOCUMENTATION PROGRESSIVE SERIES
PROGRAMS.

         Each prospective borrower completes a mortgage loan application which
includes information with respect to the applicant's liabilities, income, credit
history, employment history and personal information. Impac Funding requires a
credit report on each applicant from a credit reporting company. The report
typically contains information relating to credit history with local and
national merchants and lenders, installment debt payments and any record of
defaults, bankruptcies, repossessions or judgments.

         The Progressive Series Program allows for approval of an application
pursuant to the (a) Full/Alternative Documentation Program, or (b) the Limited
Documentation Program, the Lite Documentation Program, the "No Ratio" Program or
the "No Income, No Assets" Program (any of the foregoing, a "Reduced
Documentation Program"). The Full/Alternative Documentation Program requires the
following documents: (i) Uniform Residential Loan Application (FNMA Form 1003 or
FHLMC Form 65), (ii) Statement of Assets and Liabilities (FNMA Form 1003A or
FHLMC 65A), (iii) Residential Mortgage Credit Report with records obtained from
at least two separate repositories, (iv) Verification of Employment Form
providing a complete two year employment history, (v) Verification of Deposit
Form for all liquid assets, verifying minimum cash reserves based upon the
Loan-to-Value Ratio and borrower's income, and (vi) a Uniform Residential
Appraisal Report (FNMA Form 1004 or FHLMC Form 70). The Full/Alternative
Documentation Program allows for the use of certain alternative documents in
lieu of the Verification of Deposit Form and Verification of Employment Form.
These include W-2 Statements, tax returns and one pay check from the most recent
full month for verification of income and the most recent three months personal
bank statements for verification of liquid assets. In addition, self-employed
borrowers must provide federal tax returns for the previous two to three years,
including K-l's, federal business tax returns for two years, year-to-date
financial statements, a business credit report (for corporations) and a signed
IRS Form 4506 (Request for Copy of Tax Returns).

         Under the Limited Documentation Program, which is available to
borrowers in every Progressive Series Program, Impac Funding obtains from
prospective borrowers either a verification of deposits or bank statements for
the most recent two-month period preceding the mortgage loan application. In
addition, the Lite Documentation Program is available to Series III+, Series IV,
Series V and Series VI self-employed borrowers where the previous 12 months bank
statements are utilized in lieu of tax returns. Under these programs the
borrower provides income information on the mortgage loan application, and the
debt service- to-income ratio is calculated. However, income is not verified.
Permitted maximum Loan-to-Value Ratios (including secondary financing) under the
Limited Documentation and Lite Documentation Programs generally are limited.

         Under all Progressive Series Programs, Impac Funding or the conduit
seller verbally verifies the borrower's employment prior to closing. Credit
history, collateral quality and the amount of the down payment are important
factors in evaluating a mortgage loan submitted under one of the Reduced
Documentation Programs. In addition, in order to qualify for a Reduced
Documentation Program, a mortgage loan must conform to certain criteria
regarding maximum loan amount, property type and occupancy status. Mortgage
loans having a Loan-to-Value Ratio at origination in excess of 80% for Series I,
II and III and mortgage loans on mortgaged property used as a second or vacation
home by the prospective borrowers are not eligible for a Reduced Documentation
Program. In general, the maximum loan amount for mortgage loans underwritten in
accordance with Series I, II and III Reduced Documentation Program is $750,000
for purchase transactions and rate-term transactions and a maximum


                                      S-28


loan amount of $650,000 for cash out refinance transactions. The maximum loan
amount for mortgage loans underwritten in accordance with Series III+, IV, V and
VI Reduced Documentation Program is $450,000, however, exceptions are granted on
a case- by-case basis. Secondary financing is allowed in the origination of the
Limited Documentation Program but must meet the CLTV requirements described
above and certain other requirements for subordinate financing. In all cases,
liquid assets must support the level of income of the borrower as stated in
proportion to the type of employment of the borrower. Full Documentation is
requested by the underwriter if it is the judgment of the underwriter that the
compensating factors are insufficient for loan approval.

CREDIT HISTORY.

         The Progressive Series Program defines an acceptable credit history in
each of the Series I, II and III Programs. The Series I Program defines an
acceptable credit history as a borrower who has "A" credit, meaning a minimum of

debt in the last 12 months and may not have more than four 30-day delinquent

or at closing. Bankruptcies must be at least 6 months old. Foreclosures are not
allowed in the past 6 months.

QUALITY CONTROL.

         Impac Funding generally performs a pre-funding audit on each
Progressive Series Program mortgage loan. This audit includes a review for
compliance with Progressive Series Program parameters and accuracy of the legal
documents. Impac Funding performs a quality control review on a minimum of 25%
of the mortgage loans originated or acquired under the Progressive Series
Program for complete re-verification of employment, income and liquid assets
used to qualify for such mortgage loan. Such review also includes procedures
intended to detect evidence of fraudulent documentation and/or imprudent
activity during the processing, funding, servicing or selling of the mortgage
loan. Verification of occupancy and applicable information is made by regular
mail.

APPRAISALS.

         Impac Funding does not publish an approved appraiser list for the
conduit seller. Conduit sellers may select any appraiser of choice, regardless
of the LTV of the related loan, from the seller's approved appraiser list. At
the discretion of the underwriter a full appraisal or enhanced desk review
appraisal, or a field review appraisal may be required.

         The sponsor is responsible for maintaining an approved appraiser list
with appraisers meeting the following requirements:

o        be a state licensed or certified appraiser;

o        meet the independent appraiser requirements for staff appraisers, or,
         if appropriate, be on appraisers specified by the Office of the
         Comptroller of the Currency, the Board of Governors of the Federal
         Reserve System, the FDIC and the Office of Thrift Supervision under
         their respective real estate appraisal regulations adopted in
         accordance with Title


                                      S-30


         XI of the Financial Institutions Reform Recovery and Enforcement Act of
         1989, regardless of whether the sponsor is subject to those
         regulations;

o        be experienced in the appraisal of properties similar to the type being
         appraised;

o        be actively engaged in appraisal work; and

o        subscribe to a code of ethics that is at least as strict as the code of
         the American Institute of Real Estate Appraisers or the Society of Real
         Estate Appraisers.

         One full appraisal is required on each loan, however, an enhanced desk
review is also required when the loan amount is between $350,000 and $500,000;
the Loan-to-Value Ratio is over 90%; or the property has multiple units and the
Loan-to-Value Ratio is equal to or greater than 80%; the property is unique; or
the property exceeds 10 acres. An enhanced field review is also required when
the loan amount is above $500,000.

VARIATIONS.

         Impac Funding uses the foregoing parameters as guidelines only. On a
case-by-case basis, Impac Funding may determine that the prospective mortgagor
warrants an exception outside the standard Progressive Series Program
guidelines. An exception may be allowed if the loan application reflects certain
compensating factors, including (i) the prospective mortgagor has demonstrated
an ability to save and devote a greater portion of income to basic housing
needs; (ii) the prospective mortgagor may have a potential for increased
earnings and advancement because of education or special job training, even if
the prospective mortgagor has just entered the job market; (iii) the prospective
mortgagor has demonstrated an ability to maintain a debt free position; (iv) the
prospective mortgagor may have short term income that is verifiable but could
not be counted as stable income because it does not meet the remaining term
requirements; and (v) the prospective mortgagor's net worth is substantial
enough to suggest that repayment of the loan is within the prospective
mortgagor's ability.

THE PROGRESSIVE EXPRESS (TM) PROGRAM

GENERAL.

         In July 1996, Impac Funding developed an additional Series to the
Progressive Program, the "Progressive Express(TM) Program". The concept of the
Progressive Express(TM) Program is to underwrite the loan focusing on the
borrower's Credit Score, ability and willingness to repay the mortgage loan
obligation, and assess the adequacy of the mortgage property as collateral for
the loan. The Credit Score is an electronic evaluation of past and present
credit accounts on the borrower's credit bureau report. This includes all
reported accounts as well as public records and inquiries. The Progressive
Express(TM) Program offers six levels of mortgage loan programs. The Progressive
Express(TM) Program has a minimum Credit Score that must be met by the
borrower's primary wage earner and does not allow for exceptions to the Credit
Score requirement. The Credit Score requirement is as follows: Progressive
Express(TM) I above 680, Progressive Express(TM) II 680-620, Progressive
Express(TM) III 619-601, Progressive Express(TM) IV 600-581, Progressive
Express(TM) V 580-551, and Progressive Express(TM) VI 550-500. Each Progressive
Express(TM) program has different Credit Score requirements, credit criteria,
reserve requirements, and Loan-to-Value Ratio restrictions. Progressive
Express(TM) I is designed for credit history and income requirements typical of
"A+" credit borrowers. In the event a borrower does not fit the Progressive
Express(TM) I criteria, the borrower's mortgage loan


                                      S-31


is placed into either Progressive Express(TM) II, III, IV, V, or VI, depending
on which series' mortgage loan parameters meets the borrower unique credit
profile.

         All of the mortgage loans originated under the Progressive Express(TM)
program are underwritten either by employees of Impac Funding or by contracted
mortgage insurance companies or delegated conduit sellers. Under the Progressive
Express(TM) Program, Impac Funding underwrites single family dwellings with
Loan-to- Value Ratios at origination of up to 95%. In order for the property to
be eligible for the Progressive Express(TM) Program, it must be a single family
residence (1 unit only), condominium, and/or planned unit development (PUD).
Progressive Express(TM) Programs I through IV loans with Loan-to-Value Ratios at
origination in excess of 80% are insured by Radian. The borrower can elect to
have primary mortgage insurance covered by their loan payment. If the borrower
makes such election, a Loan-to-Value Ratio between 80.01% and 85.00% requires
25% coverage, and a Loan-to-Value Ratio between 85.01% and 95.00% requires 30%
coverage. If the borrower does not make such election, the related mortgage loan
will be covered by a modified primary mortgage insurance policy issued by Radian
to Impac Funding providing coverage in the amount of 22% for a mortgage loan
with a Loan-to-Value Ratio between 80.01% and 89.99% and of 30% for a mortgage
loan with a Loan-to-Value Ratio between 90% and 95%.

         Each borrower completes a Progressive Express(TM) Doc loan application
or a Residential Loan Application (Fannie Mae 1003 or FHLMC Form 65). The
borrower must disclose employment and assets on the application, however, there
is no verification of the information. The conduit seller obtains a verbal
verification of employment on each borrower. At the signing of loan documents,
each such borrower executes a "Borrower's Certification" certifying the
following:

o        loan terms stated on the Progressive Express(TM) Application and/or
         Residential Loan Application for the loan are true, accurate, and
         complete;

o        borrower intends to occupy the property;

o        if the property is a condominium, attached planned unit development
         (PUD), attached townhouse/rowhouse or the loan is securing a second
         home funds used to close the loan are not a gift and are from the
         Borrower's own funds;

o        borrower has four months reserves available after closing, exclusive of
         cash-out proceeds (for Progressive Express(TM) V and VI the reserve
         requirement is not applicable);

o        borrower and co-borrower, if applicable, are currently employed as
         stated on the loan application; and

o        the transaction is an arms length transaction.

         Impac Funding uses the foregoing parameters as guidelines only. Sellers
may include certain provisions in the note that Impac Funding may not enforce,
particularly, when a fixed rate loan provides in the addendum to the note for a
prepayment penalty. Full documentation is requested by the underwriter if it is
the judgment of the underwriter that the compensating factors are insufficient
for loan approval under the Progressive Product Line.

CREDIT HISTORY.

         The Progressive Express(TM) Program defines an acceptable credit

an acceptable credit history as a borrower who has "A+" credit, meaning a
minimum of four trade accounts, no 30-day delinquent mortgage payments in the
past 24 months, and a maximum of two 30-day delinquent payments on any revolving
credit accounts within the past 24 months and one 30-day delinquent payment on
any installment credit accounts within the past 24 months. All bankruptcies must
be at least 24 months old, fully discharged and the borrower must have re-

months. All bankruptcies must be at least 24 months old, fully discharged and
the borrower must have re-established a satisfactory credit history.
Foreclosures are not allowed in the past 3 years. Judgments, suits, liens,
collections or charge-offs must be paid prior to closing. Tax liens are not
allowed within the last 24 months.

         With respect to Progressive Express(TM) IV, a borrower must have a
minimum of four trade accounts, no more than two 30-day late mortgage payments
for the past 12 months or three 30-day late mortgage payments in the past 24
months. A borrower may not have more than a maximum of three 30-day or one
60-day delinquent payments on any revolving credit accounts or installment
credit accounts in the past 24 months. All bankruptcies must be at least 24
months old, fully discharged and the borrower must have re-established a
satisfactory credit history. Foreclosures are not allowed in the past 3 years.
Judgments, suits, liens, collections or charge-offs and must be paid prior to
closing. Tax liens are not allowed within the last 24 months.

         With respect to Progressive Express(TM) V, a borrower must have a
minimum of 3 trade accounts, no more than two 30-day late mortgage payments in
the past 12 months. A borrower may not have more than a maximum of two 30-day or
one 60-day delinquent payments on any revolving credit accounts or installment
credit accounts in the past 12 months. All bankruptcies must be at least 24
months old, fully discharged and the borrower must have re-established a
satisfactory credit history. Foreclosures are not allowed in the past 24 months.
Judgments, suits, liens, collections or charge-offs, may not exceed $500, and
must be paid at closing. Tax liens are not allowed within the last 12 months.

         With respect to Progressive Express(TM) VI, a borrower must have a
minimum of 3 trade accounts, no more than four 30-day or three 30-day and one
60-day late mortgage payments in the past 12 months. A borrower may not have
more than a maximum of four 30-day or two 60-day or one 90-day delinquent

past 12 months. All bankruptcies must be at least 18 months old and fully
discharged. Foreclosures are not


                                      S-33


allowed in the past 18 months. Judgments, suits, liens, collections or
charge-offs, may not exceed $1,000, and must be paid at closing. Tax liens are
not allowed within the last 12 months.

QUALITY CONTROL.

         Impac Funding generally performs a pre-funding audit on each
Progressive Express(TM) Program mortgage loan. This audit includes a review for
compliance with Progressive Express(TM) Program parameters and accuracy of the
legal documents. Impac Funding performs a quality control review on a minimum of
25% of the mortgage loans originated or acquired under the Progressive
Express(TM) Program for complete re-verification of employment, income and
liquid assets used to qualify for such mortgage loan. Such review also includes
procedures intended to detect evidence of fraudulent documentation and/or
imprudent activity during the processing, funding, servicing or selling of the
mortgage loan. Verification of occupancy and applicable information is made by
regular mail.

APPRAISALS.

         Impac Funding does not publish an approved appraiser list for the
conduit seller. Conduit sellers may select any appraiser of choice, regardless
of the LTV of the related mortgage loan, from the seller's approved appraiser
list. At the discretion of the underwriter a full appraisal or enhanced desk
review appraisal, or a field review appraisal may be required.

         The sponsor is responsible for maintaining an approved appraiser list
with appraisers meeting the following requirements:

o        be a state licensed or certified appraiser;

o        meet the independent appraiser requirements for staff appraisers, or,
         if appropriate, fee appraisers specified by the Office of the
         Comptroller of the Currency, the Board of Governors of the Federal
         Reserve System, the FDIC and the Office of Thrift Supervision
         consistent with their respective real estate appraisal regulations
         adopted in accordance with Title XI of the Financial Institutions
         Reform Recovery and Enforcement Act of 1989, regardless of whether the
         sponsor is subject to those regulations;

o        be experienced in the appraisal of properties similar to the type being
         appraised;

o        be actively engaged in appraisal work; and

o        subscribe to a code of ethics that is at least as strict as the code of
         the American Institute of Real Estate Appraisers or the Society of Real
         Estate Appraisers.

         One full appraisal is required on each loan, however, an enhanced desk
review is also required when the loan amount is between $350,000 and $500,000;
the Loan-to-Value Ratio is over 90%; the property has multiple units and the
Loan-to-Value Ratio is equal to or greater than 80%. An enhanced field review is
required when the loan amount is above $500,000.

         Impac Funding commenced acquiring mortgage loans underwritten pursuant
to the Progressive Series Program in November 1995 and pursuant to the
Progressive Express(TM) Program in late 1996. Accordingly, Impac Funding has
limited historical delinquency or default experience that may be referred to for
purposes of estimating the future delinquency and loss experience of the
mortgage loans underwritten pursuant to the Progressive Series Program and the
Progressive Express(TM) Program. It is


                                      S-34


contemplated that all of the Progressive Series Program and Progressive
Express(TM) Program mortgage loans originated or acquired by Impac Funding will
also be underwritten with a view toward the resale thereof in the secondary
mortgage market.

VARIATIONS.

         Impac Funding uses the foregoing parameters as guidelines only. On a
case-by-case basis, Impac Funding may determine that the prospective mortgagor
warrants an exception outside the standard Progressive Express(TM) Program
guidelines. An exception may be allowed if the loan application reflects certain
compensating factors, including instances where the prospective mortgagor:

o        has demonstrated an ability to save and devote a greater portion of
         income to basic housing needs;

o        may have a potential for increased earnings and advancement because of
         education or special job training, even if the prospective mortgagor
         has just entered the job market;

o        has demonstrated an ability to maintain a debt free position;

o        may have short term income that is verifiable but could not be counted
         as stable income because it does not meet the remaining term
         requirements; and

o        has net worth substantial enough to suggest that repayment of the loan
         is within the prospective mortgagor's ability.

[Description of differences with prospectus description under the heading
"Underwriting Standards"].

REPRESENTATIONS AND WARRANTIES

         In the Mortgage Loan Purchase Agreement, pursuant to which the
Depositor purchased the mortgage loans from the Sponsor, the Sponsor made
certain representations and warranties to the Depositor concerning the mortgage
loans. The Trustee will be assigned all right, title and interest in the
Mortgage Loan Purchase Agreement insofar as they relate to such representations
and warranties made by the Sponsor.

         The representations and warranties of the Sponsor with respect to the
mortgage loans include the following, among others:

         (1) The information set forth in the mortgage loan schedule is true,
complete and correct in all material respects as of the Closing Date;

         (2) Immediately prior to the sale of the mortgage loans pursuant to the
Mortgage Loan Purchase Agreement, the Sponsor was the sole owner of beneficial
title and holder of each mortgage and mortgage note relating to the mortgage
loans and as of the Closing Date, or as of another specified date, is conveying
the same to the Depositor free and clear of any encumbrance, equity,
participation interest, lien, pledge, charge, mechanics' lien, assessment, claim
or security interest, and the Sponsor has full right and authority to sell and
assign each mortgage loan pursuant to the Mortgage Loan Purchase Agreement;


                                      S-35


         (3) As of the Closing Date, the improvements on each Mortgaged Property
securing a Mortgage Loan are insured (by an insurer which is acceptable to the
Sponsor) against loss by fire, flood and such hazards as are covered under a
standard extended coverage endorsement in the locale in which the Mortgaged
Property is located, in an amount which is not less than the lesser of the
maximum insurable value of the improvements securing such Mortgage Loan or the
outstanding principal balance of the Mortgage Loan, but in no event in an amount
less than an amount that is required to prevent the Mortgagor from being deemed
to be a co-insurer thereunder;

         (4) Except to the extent insurance is in place which will cover such
damage, the physical property subject to any Mortgage is free of material damage
and is in good repair and there is no proceeding pending or threatened for the
total or partial condemnation of any Mortgaged Property;

         (5) The Mortgaged Property and all improvements thereon comply with all
requirements of any applicable zoning and subdivision laws and ordinances;

         (6) A lender's title insurance policy (on an ALTA or CLTA form) or
binder, or other assurance of title customary in the relevant jurisdiction
therefor in a form acceptable to Fannie Mae or Freddie Mac, was issued on the
date that each Mortgage Loan was created by a title insurance company which, to
the best of the Sponsor's knowledge, was qualified to do business in the
jurisdiction where the related Mortgaged Property is located, insuring the
Sponsor and its successors and assigns that the Mortgage is a first priority
lien on the related Mortgaged Property in the original principal amount of the
Mortgage Loan. The Sponsor is the sole insured under such lender's title
insurance policy, and such policy, binder or assurance is valid and remains in
full force and effect, and each such policy, binder or assurance shall contain
all applicable endorsements including a negative amortization endorsement, if
applicable;

         (7) As of the Closing Date there is no material monetary default
existing under any Mortgage or the related Mortgage Note and there is no
material event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a default, breach or event of
acceleration; and neither the Sponsor nor any of its respective affiliates has
taken any action to waive any default, breach or event of acceleration; and no
foreclosure action is threatened or has been commenced with respect to the
Mortgage Loan;

         (8) Neither the Sponsor nor any prior holder of any Mortgage has
impaired, waived, altered or modified the Mortgage or Mortgage Notes in any
material respect (except that a Mortgage Loan may have been modified by a
written instrument which has been recorded, if necessary to protect the
interests of the owner of such Mortgage Loan or the Bonds, and which has been
delivered to the Trustee); satisfied, canceled or subordinated such Mortgage in
whole or in part; released the applicable Mortgaged Property in whole or in part
from the lien of such Mortgage; or executed any instrument of release,
cancellation or satisfaction with respect thereto; and

         (9) At the time of origination, if required, each Mortgaged Property
was the subject of an appraisal which conforms to the underwriting requirements
of the related originator; the Mortgage File contains an appraisal of the
applicable Mortgaged Property.

In the case of a breach of any representation or warranty set forth above which
materially and adversely affects the value of the interests of Bondholders or
the Certificateholders, as applicable, or of the Depositor in any of the
mortgage loans, the Sponsor shall, within 90 days from the date of its discovery
or receipt of notice thereof, cure such breach or repurchase event in all
material respects or shall either (i) repurchase such Mortgage Loan from the
Issuing Entity at the repurchase price, or (ii) substitute one or more Eligible
Substitute Mortgage Loans for such Mortgage Loan, in each case in the manner and
subject


                                      S-36


to the conditions set forth in Mortgage Loan Purchase Agreement. The
obligations of the Sponsor to cure, repurchase or substitute shall constitute
the sole and exclusive remedy respecting a breach of such representations and
warranties available to the Depositor, the Issuing Entity, the
Certificateholders and the Bondholders against the sponsor.

ADDITIONAL INFORMATION

         The description in this prospectus supplement of the mortgage pool and
the mortgaged properties is based upon the mortgage pool as constituted at the
close of business on the Cut-off Date, as adjusted for the scheduled principal
payments due on or before this date. Prior to the issuance of the Certificates,
mortgage loans may be removed from the mortgage pool as a result of incomplete
documentation or otherwise if the depositor deems this removal necessary or
desirable, and may be prepaid at any time. A limited number of other mortgage
loans may be included in the mortgage pool prior to the issuance of the
Certificates unless including these mortgage loans would materially alter the
characteristics of the mortgage pool as described in this prospectus supplement.
The depositor believes that the information set forth in this prospectus
supplement will be representative of the characteristics of the mortgage pool as
it will be constituted at the time the Certificates are issued, although the
range of mortgage rates and maturities and other characteristics of the mortgage
loans may vary. In no event, however, will more than 5% (by principal balance at
the Cut- off Date) of the mortgage loans deviate from the characteristics of the
mortgage loans set forth in the related prospectus supplement.

         If, as of the Closing Date, any material pool characteristic differs by
5% or more from the description in this prospectus supplement, revised
disclosure will be provided either in a supplement or in a current report on
Form 8-K.

                             STATIC POOL INFORMATION

         Static pool information material to this offering may be found at
__________________________. The Sponsor does not have any material static pool
information with respect to any mortgage loans of the same type as those
included in the trust fund originated by it prior to January 1, 2006, because
all or substantially all of these mortgage loans originated by the Sponsor prior
to that time were sold on a servicing released basis, and such information may
not be obtained without unreasonable effort or expense. With respect to any of
these mortgage loans originated by the Sponsor on or after January 1, 2006, the
static pool information provided does not include any information with respect
to any mortgage loan which was sold on a servicing released basis, except to the
extent the purchaser of that loan or another third-party has agreed to provide
that information back to the Sponsor and has actually provided it to the Sponsor
with indemnification.

         Information provided through the Internet address above will not be
deemed to be a part of this prospectus or the registration statement for the
securities offered hereby if it relates to any prior securities pool or vintage
formed before January 1, 2006, or with respect to the mortgage pool (if
applicable), any period before January 1, 2006.

                            YIELD ON THE CERTIFICATES

DELAY IN DISTRIBUTIONS ON THE OFFERED CERTIFICATES

         The effective yield to holders of the offered certificates of each
class will be less than the yields otherwise produced by their respective
Pass-Through Rates and purchase prices because (1) on the first distribution
date one month's interest is payable even though __ days will have elapsed from
the date on which interest begins to accrue, (2) on each succeeding distribution
date the interest payable is the interest


                                      S-37


accrued during the month preceding the month of the distribution date, which
ends __ days prior to the distribution date and (3) during each Interest Accrual
Period (other than the first Interest Accrual Period), interest accrues on a
Certificate Principal Balance or Notional Amount that is less than the
Certificate Principal Balance or Notional Amount of the class actually
outstanding for the first __ days of this Interest Accrual Period.

SHORTFALLS IN COLLECTIONS OF INTEREST

         When a principal prepayment in full is made on a mortgage loan, the
mortgagor is charged interest only for the period from the Due Date of the
preceding monthly payment up to the date of the principal prepayment, instead of
for a full month. When a partial principal prepayment is made on a mortgage
loan, the mortgagor is not charged interest on the amount of the prepayment for
the month in which the prepayment is made. In addition, the application of the
Relief Act to any mortgage loan will adversely affect, for an indeterminate
period of time, the ability of the Master Servicer to collect full amounts of
interest on the mortgage loan. See "Legal Aspects of the Mortgage
Loans--Soldiers' and Sailors' Civil Relief Act of 1940" in the prospectus. The
Master Servicer is obligated to pay from its own funds only those interest
shortfalls attributable to full and partial prepayments by the mortgagors on the
mortgage loans master serviced by it, but only to the extent of its aggregate
Servicing Fee for the related Due Period. See "Pooling and Servicing
Agreement--Servicing and Other Compensation and Payment of Expenses" in this
prospectus supplement. Accordingly, the effect of (1) any principal prepayments
on the mortgage loans, to the extent that any resulting Prepayment Interest
Shortfall exceeds any Compensating Interest or (2) any shortfalls resulting from
the application of the Relief Act, will be to reduce the aggregate amount of
interest collected that is available for distribution to holders of the
Certificates. Any resulting shortfalls will be allocated among the Certificates
as provided in this prospectus supplement under "Description of the
Certificates--Interest Distributions".

GENERAL PREPAYMENT CONSIDERATIONS

The rate of principal payments on each class of offered certificates (other than
the Class XS Certificates), the aggregate amount of distributions on each class
of offered certificates and the yield to maturity of each class of offered
certificates will be related to the rate and timing of payments of principal on
the mortgage loans. The rate of principal payments on the mortgage loans will in
turn be affected by the amortization schedules of the mortgage loans and by the
rate of principal prepayments on the mortgage loans (including for this purpose
payments resulting from refinancings, liquidations of the mortgage loans due to
defaults, casualties, condemnations and repurchases, whether optional or
required, by the depositor, the Sponsor, the Originator or the Master Servicer,
as the case may be). The mortgage loans generally may be prepaid by the
mortgagors at any time; however, as described under "The Mortgage Pool" in this
prospectus supplement, with respect to approximately _____% of the mortgage
loans, by aggregate principal balance as of the Cut-off Date, a prepayment may
subject the related mortgagor to a prepayment charge. All of the mortgage loans
contain due-on-sale clauses. As described under "Description of the
Certificates--Principal Distributions on the Senior Certificates" in this
prospectus supplement, prior to the distribution date in ________ ____, all
principal prepayments on the mortgage loans will be allocated to the Senior
Certificates (other than the Class XS Certificates). Thereafter, as further
described in this prospectus supplement, during some periods, subject to loss
and delinquency criteria described in this prospectus supplement, the Senior
Prepayment Percentage may continue to be disproportionately large (relative to
the Senior Percentage) and the percentage of principal prepayments payable to
the Subordinate Certificates may continue to be disproportionately small.

         Prepayments, liquidations and repurchases of the mortgage loans will
result in distributions in respect of principal to the holders of the class or
classes of offered certificates then entitled to receive these principal
distributions that otherwise would be distributed over the remaining terms of
the mortgage


                                      S-38


loans. See "Maturity and Prepayment Considerations" in the prospectus. Since the
rates of payment of principal on the mortgage loans will depend on future events
and a variety of factors (as described more fully in this prospectus supplement
and in the prospectus under "Yield Considerations" and "Maturity and Prepayment
Considerations"), no assurance can be given as to the rate of principal
prepayments. The extent to which the yield to maturity of any class of offered
certificates (other than the Class XS Certificates) may vary from the
anticipated yield will depend upon the degree to which they are purchased at a
discount or premium and the degree to which the timing of payments on the
offered certificates is sensitive to prepayments on the mortgage loans. Further,
an investor should consider, in the case of any offered certificate purchased at
a discount, the risk that a slower than anticipated rate of principal payments
on the mortgage loans could result in an actual yield to an investor that is
lower than the anticipated yield and, in the case of any offered certificate
purchased at a premium, the risk that a faster than anticipated rate of
principal payments could result in an actual yield to the investor that is lower
than the anticipated yield. In general, the earlier a prepayment of principal on
the mortgage loans, the greater will be the effect on the investor's yield to
maturity. As a result, the effect on an investor's yield of principal payments
occurring at a rate higher (or lower) than the rate anticipated by the investor
during the period immediately following the issuance of the offered certificates
would not be fully offset by a subsequent like reduction (or increase) in the
rate of principal payments.

         The yield to maturity on the Class XS Certificates will be extremely
sensitive to prepayments on the mortgage loans generally, and most sensitive to
prepayments on mortgage loans with relatively high mortgage rates. See "--Yield
Sensitivity of the Class XS Certificates" in this prospectus supplement.

         It is highly unlikely that the mortgage loans will prepay at any
constant rate until maturity or that all of the mortgage loans will prepay at
the same rate. Moreover, the timing of prepayments on the mortgage loans may
significantly affect the actual yield to maturity on the offered certificates,
even if the average rate of principal payments experienced over time is
consistent with an investor's expectation.

         Because principal distributions are paid to some classes of offered
certificates before other classes, holders of classes of offered certificates
having a later priority of payment bear a greater risk of losses (because the
offered certificates will represent an increasing percentage interest in the
trust fund during the period prior to the commencement of distributions of
principal thereon) than holders of classes having earlier priorities for
distribution of principal. In particular with respect to the Lockout
Certificates, as described under "Description of the Certificates--Principal
Distributions on the Senior Certificates" in this prospectus supplement, during
some periods, no principal payments or a disproportionately small portion of the
Senior Principal Distribution Amount will be distributed on the Lockout
Certificates, and during other periods, a disproportionately large portion of
the Senior Principal Distribution Amount will be distributed on the Lockout
Certificates. Unless the Certificate Principal Balances of the Class A
Certificates (other than the Lockout Certificates) have been reduced to zero,
the Lockout Certificates will not be entitled to receive any distributions of
principal payments prior to the distribution date in ________ ____.

         The rate of payments (including prepayments) on pools of mortgage loans
is influenced by a variety of economic, geographic, social and other factors. If
prevailing mortgage rates fall significantly below the mortgage rates on the
mortgage loans, the rate of prepayment (and refinancing) would be expected to
increase. Conversely, if prevailing mortgage rates rise significantly above the
mortgage rates on the mortgage loans, the rate of prepayment on the mortgage
loans would be expected to decrease. Other factors affecting prepayment of
mortgage loans include changes in mortgagors' housing needs, job transfers,
unemployment, mortgagors' net equity in the mortgaged properties and servicing
decisions. There can be no certainty as to the rate of prepayments on the
mortgage loans during any period or over the life of the Certificates. See
"YIELD CONSIDERATIONS" and "MATURITY AND PREPAYMENT CONSIDERATIONS" in the
prospectus.


                                      S-39


         In general, defaults on mortgage loans are expected to occur with
greater frequency in their early years. In addition, default rates generally are
higher for mortgage loans used to refinance an existing mortgage loan. In the
event of a mortgagor's default on a mortgage loan, there can be no assurance
that recourse beyond the specific mortgaged property pledged as security for
repayment will be available. See "The Mortgage Pool--Underwriting Standards;
Representations" in this prospectus supplement.

MARKET INTEREST RATE AND SUBORDINATION YIELD CONSIDERATIONS

         Because the mortgage rates on the mortgage loans and the Pass-Through
Rates on the offered certificates (other than the Class XS Certificates) are
fixed, these rates will not change in response to changes in market interest
rates. Accordingly, if mortgage market interest rates or market yields for
securities similar to these offered certificates were to rise, the market value
of these offered certificates may decline.

         As described under "DESCRIPTION OF THE CERTIFICATES--ALLOCATION OF
LOSSES; SUBORDINATION", amounts otherwise distributable to holders of the
Subordinate Certificates may be made available to protect the holders of the
Senior Certificates against interruptions in distributions due to mortgagor
delinquencies, to the extent not covered by P&I Advances, and amounts otherwise
distributable to holders of the Subordinate Certificates with a higher numerical
class designation may be made available to protect the holders of Subordinate
Certificates with a lower numerical class designation against interruptions in
distributions. Delinquencies may affect the yield to investors on the
Subordinate Certificates, and, even if subsequently cured, will affect the
timing of the receipt of distributions by the holders of the Subordinate
Certificates. In addition, a larger than expected rate of delinquencies or
losses will affect the rate of principal payments on each class of the
Subordinate Certificates if it delays the scheduled reduction of the Senior
Prepayment Percentage, triggers an increase of the Senior Prepayment Percentage
to [100]% or triggers a lockout of one or more classes of Subordinate
Certificates from distributions of portions of the Subordinate Principal
Distribution Amount. See "Description of the Certificates--Principal
Distributions on the Senior Certificates" and "--Principal Distributions on the
Subordinate Certificates" in this prospectus supplement.

WEIGHTED AVERAGE LIFE

         Weighted average life refers to the amount of time that will elapse
from the date of issuance of a security until each dollar of principal of the
security will be repaid to the investor. The weighted average life of the
offered certificates of each class will be influenced by the rate at which
principal on the mortgage loans is paid, which may be in the form of scheduled
payments or prepayments (including prepayments of principal by the mortgagor as
well as amounts received by virtue of condemnation, insurance or foreclosure
with respect to the mortgage loans), and the timing thereof.

         Except as otherwise described under "DESCRIPTION OF THE
CERTIFICATES--PRINCIPAL DISTRIBUTIONS ON THE SENIOR CERTIFICATES" in this
prospectus supplement, distributions of principal will be made to the classes of
Class A Certificates according to the priorities described in this prospectus
supplement, rather than on a pro rata basis among the Class A Certificates,
unless the Certificate Principal Balances of the Subordinate Certificates have
been reduced to zero. The timing of commencement of principal distributions and
the weighted average life of each class of Class A Certificates will be affected
by the rates of prepayment on the mortgage loans experienced both before and
after the commencement of principal distributions on each class of Class A
Certificates. Moreover, because the Lockout Certificates do not receive (unless
the Certificate Principal Balances of the Class A Certificates, other than the
Lockout Certificates, have been reduced to zero) any portion of principal
payments prior to the distribution date occurring in ________ ____ and
thereafter will receive (unless the Certificate Principal Balances of the Class
A Certificates, other than the Lockout Certificates, have been reduced to zero)
a


                                      S-40


disproportionately small or large portion of principal payments, the weighted
average life of the Lockout Certificates will be longer or shorter than would
otherwise be the case, and the effect on the market value of the Lockout
Certificates of changes in market interest rates or market yields for similar
securities may be greater or lesser than for the other classes of Class A
Certificates entitled to principal distributions.

         Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. The model used in this prospectus supplement is
the Prepayment Assumption No representation is made that the mortgage loans in
the mortgage pool will prepay at the above-described rates or any other rate.
CPR refers to the Constant Prepayment Rate model, which assumes that the
outstanding principal balance of a pool of mortgage loans prepays at a specified
constant annual rate or CPR. In generating monthly cash flows, this rate is
converted to an equivalent constant monthly rate. To assume __% CPR or any other
CPR percentage is to assume that the stated percentage of the outstanding
principal balance of the pool is prepaid over the course of a year.

         The tables following the next paragraph indicate the percentage of the
initial Certificate Principal Balance of the indicated classes of Certificates
that would be outstanding after each of the dates shown at various constant
percentages of the Prepayment Assumption and the corresponding weighted average
life of the indicated class of Certificates. The table is based on the following
modeling assumptions (the "Structuring Assumptions"):

         (1) the mortgage pool consists of ____ mortgage loans with the
characteristics set forth in the table below,

         (2) distributions on the indicated Certificates are received, in cash,
on the ___ day of each month, commencing in __________  ______,

         (3) the mortgage loans prepay at the constant percentages of the
Prepayment Assumption indicated,

         (4) no defaults or delinquencies occur in the payment by mortgagors of
principal and interest on the mortgage loans and no shortfalls due to the
application of the Relief Act are incurred,

         (5) none of the depositor, the Sponsor, the Originator, the Master
Servicer or any other person purchases from the trust fund any mortgage loan
pursuant to any obligation or option under the Agreement (except as indicated in
footnote (2) in the tables),

         (6) scheduled monthly payments on the mortgage loans are received on
the first day of each month commencing in ________ ____, and are computed prior
to giving effect to any prepayments received in the prior month,

         (7) prepayments representing payment in full of individual mortgage
loans are received on the last day of each month commencing in _______ ____, and
include 30 days' interest,

         (8) the scheduled monthly payment for each mortgage loan is calculated
based on its principal balance, mortgage rate and remaining term to maturity so
that the mortgage loan will amortize in amounts sufficient to repay the
remaining principal balance of the mortgage loan by its remaining term to
maturity,

         (9)      the Certificates are purchased on _______ __, ____ and


                                      S-41


         (10) the Servicing Fee Rate is ____% per annum and the Trustee's Fee
Rate is _____% per annum.

         There will be discrepancies between the characteristics of the actual
mortgage loans and the characteristics assumed in preparing the table below. Any
discrepancy may have an effect upon the percentages of the initial Certificate
Principal Balances outstanding (and the weighted average lives) of the classes
of Certificates set forth in the table. In addition, to the extent that the
actual mortgage loans included in the mortgage pool have characteristics that
differ from those assumed in preparing the table below, the classes of
Certificates set forth below may mature earlier or later than indicated by the
table below. Based on the foregoing Structuring Assumptions, the table below
indicates the weighted average life of each class of the Class A Certificates
and the Subordinate Certificates and sets forth the percentage of the initial
Certificate Principal Balance of each of these Certificates that would be
outstanding after each of the dates shown, at various percentages of the
Prepayment Assumption. Neither the prepayment model used in this prospectus
supplement nor any other prepayment model or assumption purports to be a
historical description of prepayment experience or a prediction of the
anticipated rate of prepayment of any pool of mortgage loans, including the
mortgage loans included in the trust fund. Variations in the prepayment
experience and the balance of the mortgage loans that prepay may increase or
decrease the percentages of initial Certificate Principal Balance (and weighted
average lives) shown in the following table. Variations may occur even if the
average prepayment experience of all of the mortgage loans equals any of the
specified percentages of the Prepayment Assumption.

(1) The weighted average life of a Certificate is determined by (a) multiplying
the amount of each distribution of principal by the number of years from the
date of issuance of the Certificate to the related distribution date, (b) adding
the results and (c) dividing the sum by the initial Certificate Principal
Balance of the Certificate.

(2) Calculated pursuant to footnote one but assumes the Master Servicer
exercises its option to purchase the mortgage loans. See "Pooling and Servicing
Agreement-- Termination" in this prospectus supplement.



         There is no assurance that prepayments of the mortgage loans will
conform to any of the levels of the Prepayment Assumption indicated in the table
above or to any other level, or that the actual weighted average life of any
class of Certificates will conform to any of the weighted average lives set
forth in the table above. Furthermore, the information contained in the table
with respect to the weighted average life of each specified class of
Certificates is not necessarily indicative of the weighted average life that
might be calculated or projected under different or varying prepayment
assumptions.

         The characteristics of the mortgage loans will differ from those
assumed in preparing the table above. In addition, it is unlikely that any
mortgage loan will prepay at any constant percentage of the Prepayment
Assumption until maturity or that all of the mortgage loans will prepay at the
same rate. The timing of changes in the rate of prepayments may significantly
affect the actual yield to maturity to investors, even if the average rate of
principal prepayments is consistent with the expectations of investors.

YIELD SENSITIVITY OF THE CLASS XS CERTIFICATES

         The yield to maturity of the Class XS Certificates will be extremely
sensitive to the prepayment, repurchase and default experience on the mortgage
loans, which may fluctuate significantly from time to time. A rapid rate of
principal payments on the mortgage loans will have a materially negative effect
on the yield to maturity of the Class XS Certificates, and principal prepayments
on mortgage loans with higher mortgage rates will have a greater negative impact
on the yield to maturity of the Class XS Certificates than principal prepayments
on mortgage loans with lower mortgage rates. There can be no assurance that the
mortgage loans will prepay at any particular rate. Prospective investors in the
Class XS Certificates should fully consider the associated risks, including the
risk that they may not fully recover their initial investment.

         The following table indicates the sensitivity of the yield of the Class
XS Certificates to various rates of prepayment on the mortgage loans and the
corresponding pre-tax yield on a corporate bond equivalent basis. The table set
forth below has been prepared based on the modeling assumptions.

PRE-TAX YIELD TO MATURITY ON THE CLASS XS CERTIFICATES AT VARIOUS PERCENTAGES OF
                            THE PREPAYMENT ASSUMPTION



                     ASSUMED AGGREGATE PURCHASE PRICE PERCENTAGES OF THE PREPAYMENT ASSUMPTION

                                                                                       
                                      0%           25%          50%        75%        100%        125%      150%




         On the basis of a constant prepayment rate of approximately ___% of the
Prepayment Assumption and the purchase price assumed above, the yield to
maturity of the Class XS Certificates would be approximately __%. If the actual
prepayment rate were to exceed this rate, initial investors in the Class XS
Certificates would not fully recover their initial investment.


                                      S-43


         The pre-tax yields set forth in the preceding table were calculated by
determining the monthly discount rates that, when applied to the assumed streams
of cash flows to be paid on the Class XS Certificates, would cause the
discounted present value of these assumed stream of cash flows to equal the
assumed purchase price of the Class XS Certificates, and by converting the
monthly rates to corporate bond equivalent rates. This calculation does not take
into account shortfalls in collection of interest due to prepayments (or other
liquidations) on the mortgage loans or the interest rates at which investors may
be able to reinvest funds received by them as distributions on the Class XS
Certificates and consequently does not purport to reflect the return on any
investment in the Class XS Certificates when the reinvestment rates are
considered.

         The characteristics of the mortgage loans will differ from those
assumed in preparing the table above. There can be no assurance that the cash
flows on the Class XS Certificates will correspond to those used to determine
the pre-tax yields shown above or that the aggregate purchase price of the Class
XS Certificates will be as assumed. It is unlikely that any mortgage loan will
prepay at the specified percentages of the Prepayment Assumption until maturity
or that all of the mortgage loans will prepay at the same rate. The timing of
changes in the rate of prepayments may significantly affect the actual yield to
maturity to investors, even if the average rate of principal prepayments is
consistent with the expectations of investors. The portion of interest payments
on the mortgage loans distributable to the Class XS Certificates will vary from
mortgage loan to mortgage loan, and will be greater with respect to mortgage
loans with higher mortgage rates. Accordingly, the yield on the Class XS
Certificates will be lower than indicated in the applicable table above with
respect to any particular average prepayment rate if mortgage loans with higher
mortgage rates prepay faster than mortgage loans with lower mortgage rates,
assuming no variation in mortgage loan principal balance. Moreover, the variable
Pass-Through Rate on the Class XS Certificates will generally decrease as the
Certificate Principal Balances of Class A Certificates with lower fixed
Pass-Through Rates decline. There can be no assurance that the mortgage loans
will prepay at any of the rates shown in the table or at any other particular
rate, or that mortgage loans with relatively high mortgage rates will prepay at
the same rate as the mortgage loans generally. Investors must make their own
decisions as to the appropriate prepayment assumptions to be used in deciding
whether to purchase the Class XS Certificates.

YIELD SENSITIVITY OF THE SUBORDINATE CERTIFICATES

         If the Certificate Principal Balances of the Class B-6 Certificates,
Class B-5 Certificates, Class B-4 Certificates, Class B-3 Certificates and Class
B-2 Certificates have been reduced to zero, the yield to maturity on the Class
B-1 Certificates will become extremely sensitive to losses on the mortgage loans
(and the timing thereof) that are covered by subordination, because the entire
amount of losses on the mortgage loans will be allocated to the Class B-1
Certificates. If the Certificate Principal Balances of the Class B-6
Certificates, Class B-5 Certificates, Class B-4 Certificates and Class B-3
Certificates have been reduced to zero, the yield to maturity on the Class B-2
Certificates will become extremely sensitive to losses on the mortgage loans
(and the timing thereof) that are covered by subordination, because the entire
amount of losses on the mortgage loans will be allocated to the Class B-2
Certificates. If the Certificate Principal Balances of the Class B-6
Certificates, Class B-5 Certificates and Class B-4 Certificates have been
reduced to zero, the yield to maturity on the Class B-3 Certificates will become
extremely sensitive to losses on the mortgage loans (and the timing thereof)
that are covered by subordination, because the entire amount of losses on the
mortgage loans will be allocated to the Class B-3 Certificates. The initial
undivided interest in the trust fund evidenced by the Class B-1 Certificates,
the Class B-2 Certificates, the Class B-3 Certificates, the Class B-4
Certificates, the Class B-5 Certificates and the Class B-6 Certificates is
approximately ____%, approximately ____%, approximately ____%, approximately
____%, approximately ____% and approximately ____%, respectively. Investors in
the Subordinate Certificates should fully consider the risk that Realized Losses
on the mortgage loans could result in the failure of these investors to fully
recover their investments. For additional considerations


                                      S-44


relating to the yield on the Subordinate Certificates, see "Yield
Considerations" and "Maturity and Prepayment Considerations" in the prospectus.

ADDITIONAL YIELD CONSIDERATIONS APPLICABLE SOLELY TO THE RESIDUAL CERTIFICATES

         The certificateholders' after-tax rate of return on their Residual
Certificates will reflect their pre-tax rate of return, reduced by the taxes
required to be paid with respect to the Residual Certificates. Holders of
Residual Certificates will have tax liabilities with respect to their Residual
Certificates during the early years of the REMIC's term that substantially
exceed any distributions payable thereon during or prior to any such period. In
addition, holders of Residual Certificates will have tax liabilities with
respect to their Residual Certificates the present value of which substantially
exceeds the present value of distributions payable thereon and of any tax
benefits that may arise with respect thereto. Accordingly, the after-tax rate of
return on the Residual Certificates may be negative or may otherwise be
significantly adversely affected. The timing and amount of taxable income
attributable to the Residual Certificates will depend on, among other things,
the timing and amounts of prepayments and losses experienced with respect to the
mortgage pool.

         The Residual Certificateholders are encouraged to consult their own tax
advisors as to the effect of taxes and the receipt of any payments made to these
holders in connection with the transfer of the Residual Certificates on
after-tax rates of return on the Residual Certificates. See "Federal Income Tax
Consequences" in this prospectus supplement and in the prospectus.

                         DESCRIPTION OF THE CERTIFICATES

GENERAL

         The Series ____-___ Certificates will consist of ________ classes of
certificates. Only the offered certificates are offered by this prospectus
supplement.

         The Certificates represent in the aggregate the entire beneficial
ownership interest in a trust fund consisting primarily of a mortgage pool of
mortgage loans and an aggregate principal balance as of the Cut- off Date, after
application of scheduled payments due whether or not received, of approximately
$___________, subject to a permitted variance as described in this prospectus
supplement under "The Mortgage Pool".

         Each class of the offered certificates will have the approximate
initial Certificate Principal Balance or Notional Amount, as applicable, as set
forth on the cover hereof and will have the Pass-Through Rate determined as
provided under "Summary--Pass-Through Rate" and "--Interest Distributions" in
this prospectus supplement. The Residual Certificates also represent the right
to receive additional distributions in respect of the trust fund on any
distribution date after all required payments of principal and interest have
been made on this date in respect of the other classes of Certificates, although
it is not anticipated that funds will be available for any additional
distribution. The Class B-4 Certificates, Class B-5 Certificates and Class B-6
Certificates have in the aggregate an initial Certificate Principal Balance of
approximately $__________ and a fixed Pass-Through Rate for each distribution
date of ____% per annum. The Class B-4 Certificates, the Class B-5 Certificates
and the Class B-6 Certificates, which are not being offered by this prospectus
supplement, will be sold by the depositor to _________________________ on the
Closing Date.

         The Class A Certificates will be issued, maintained and transferred on
the book-entry records of DTC and its participants in minimum denominations of
$_____ and integral multiples of $____ in excess thereof. The Class XS
Certificates and the Subordinate Certificates will be issued in registered,


                                      S-45


certificated form, in minimum percentage interests corresponding to initial
Certificate Principal Balances or notional amounts, as applicable, of $______
and integral multiples of $_____ in excess thereof, except that one Certificate
of each of these classes may be issued evidencing an amount equal to either (1)
the sum of an otherwise authorized denomination thereof plus the remainder of
the aggregate initial Certificate Principal Balance or Notional Amount, as
applicable, for the class or (2) the remainder. The Residual Certificates will
be offered in registered, certificated form, in minimum denominations of $___
and integral multiples thereof.

         The Book-Entry Certificates will initially be represented by one or
more global certificates registered in the name of a nominee of DTC. The
depositor has been informed by DTC that DTC's nominee will be Cede & Co. No
person acquiring an interest in any class of the Book-Entry Certificates will be
entitled to receive a certificate representing such person's interest, except as
set forth below under "--Definitive Certificates". Unless and until definitive
certificates are issued under the limited circumstances described in this
prospectus supplement, all references to actions by certificateholders with
respect to the Book-Entry Certificates shall refer to actions taken by DTC upon
instructions from its participants and all references in this prospectus
supplement to distributions, notices, reports and statements to
certificateholders with respect to the Book-Entry Certificates shall refer to
distributions, notices, reports and statements to DTC or CEDE, as the registered
holder of the Book-Entry Certificates, for distribution to Certificate Owners in
accordance with DTC procedures. See "--Registration of the Book-Entry
Certificates" and "--Definitive Certificates" in this prospectus supplement.

         The Class XS Certificates, the Class B-1 Certificates, the Class B-2
Certificates, the Class B-3 Certificates, the Residual Certificates and the
definitive certificates will be transferable and exchangeable at the offices of
the Trustee. The Subordinate Certificates and the Residual Certificates may not
be purchased by or transferred to a Plan except upon delivery of a certification
of facts or an opinion of counsel, as provided in this prospectus supplement.
See "--Restrictions on Transfer of the Subordinate Certificates and the Residual
Certificates" and "ERISA Considerations" in this prospectus supplement. Transfer
of the Residual Certificates will be subject to additional restrictions and
transfer of the Residual Certificates to any non-United States person will be
prohibited, in each case as described under "Federal Income Tax
Consequences--Special Tax Considerations Applicable to Residual Certificates" in
this prospectus supplement and under "Federal Income Tax
Consequences--REMICs--Tax On Transfers of REMIC Residual Certificates to Certain
Organizations" and "--Taxation of Owners of Residual Certificates--Noneconomic
REMIC Residual Certificates" in the prospectus. No service charge will be
imposed for any registration of transfer or exchange, but the Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge imposed in connection therewith.

         All distributions to holders of the Certificates, other than the final
distribution on any class of Certificates, will be made on each distribution
date by or on behalf of the Trustee to the persons in whose names the
Certificates are registered at the close of business on the related Record Date.
Distributions will be made either (a) by check mailed to the address of each
certificateholders as it appears in the Certificate Register or (b) upon written
request to the Trustee at least five business days prior to the relevant Record
Date by any holder of Certificates having an aggregate initial Certificate
Principal Balance or Notional Amount, as applicable, that is in excess of the
lesser of (1) $5,000,000 or (2) two-thirds of the initial aggregate Certificate
Principal Balance or Notional Amount, as applicable, of the class of
Certificates, by wire transfer in immediately available funds to the account of
the certificateholders specified in the request. The final distribution on any
class of Certificates will be made in like manner, but only upon presentment and
surrender of the class at the corporate trust office of the Trustee or any other
location specified in the notice to certificateholders of the final
distribution.


                                      S-46


REGISTRATION OF THE BOOK-ENTRY CERTIFICATES

         DTC is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. DTC was created to hold securities for its participants and to
facilitate the clearance and settlement of securities transactions between
participants through electronic book entries, thereby eliminating the need for
physical movement of certificates.

         Certificate Owners that are not participants or indirect participants
but desire to purchase, sell or otherwise transfer ownership of, or other
interests in, the Book-Entry Certificates may do so only through participants
and indirect participants. In addition, Certificate Owners will receive all
distributions of principal of and interest on the Book-Entry Certificates from
the Trustee through DTC and DTC participants. The Trustee will forward payments
to DTC in same day funds and DTC will forward payments to participants in next
day funds settled through the New York Clearing House. Each participant will be
responsible for disbursing the payments. Unless and until definitive
certificates are issued, it is anticipated that the only certificateholders of
the Book-Entry Certificates will be CEDE, as nominee of DTC. Certificate Owners
will not be recognized by the Trustee as certificateholders, as such term is
used in the Agreement and Certificate Owners will be permitted to exercise the
rights of certificateholders only indirectly through DTC and its participants.

         Under the Rules, DTC is required to make book-entry transfers of
Book-Entry Certificates among participants and to receive and transmit
distributions of principal of, and interest on, the Book-Entry Certificates.
participants and indirect participants with which Certificate Owners have
accounts with respect to the Book-Entry Certificates similarly are required to
make book-entry transfers and receive and transmit these payments on behalf of
their respective Certificate Owners. Accordingly, although Certificate Owners
will not possess definitive certificates, the Rules provide a mechanism by which
Certificate Owners through their participants and indirect participants will
receive payments and will be able to transfer their interest.

Because DTC can only act on behalf of participants, who in turn act on behalf of
indirect participants and on behalf of certain banks, the ability of a
Certificate Owner to pledge Book-Entry Certificates to persons or entities that
do not participate in the DTC system, or to otherwise act with respect to
Book-Entry Certificates, may be limited due to the absence of physical
certificates for the Book-Entry Certificates. In addition, under a book-entry
format, Certificate Owners may experience delays in their receipt of payments
since distribution will be made by the Trustee to CEDE, as nominee for DTC.

         Under the Rules, DTC will take action permitted to be taken by a
certificateholders under the Agreement only at the direction of one or more
participants to whose DTC account the Book-Entry Certificates are credited.
Additionally, under the Rules, DTC will take actions with respect to specified
Voting Rights only at the direction of and on behalf of participants whose
holdings of Book-Entry Certificates evidence these specified Voting Rights. DTC
may take conflicting actions with respect to Voting Rights, to the extent that
participants whose holdings of Book-Entry Certificates evidence Voting Rights,
authorize divergent action.

         The depositor, the Master Servicer and the Trustee will have no
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the Book-Entry Certificates held by CEDE,
as nominee for DTC, or for maintaining, supervising or reviewing any records
relating to beneficial ownership interests.


                                      S-47


DEFINITIVE CERTIFICATES

         Definitive certificates will be issued to Certificate Owners or their
nominees, respectively, rather than to DTC or its nominee, only if (1) the
depositor advises the Trustee in writing that DTC is no longer willing or able
to discharge properly its responsibilities as clearing agency with respect to
the Book-Entry Certificates and the depositor is unable to locate a qualified
successor, (2) the depositor, at its option, elects to terminate the book-entry
system through DTC, or (3) after the occurrence of an Event of Default,
Certificate Owners representing in the aggregate not less than 51% of the Voting
Rights of the Book-Entry Certificates advise the Trustee and DTC through
participants, in writing, that the continuation of a book-entry system through
DTC (or a successor thereto) is no longer in the Certificate Owners' best
interest.

         Upon the occurrence of any event described in the immediately preceding
paragraph, the Trustee is required to notify all Certificate Owners through
participants of the availability of definitive certificates. Upon surrender by
DTC of the definitive certificates representing the Book-Entry Certificates and
receipt of instructions for re-registration, the Trustee will reissue the
Book-Entry Certificates as definitive certificates issued in the respective
principal amounts owned by individual Certificate Owners, and thereafter the
Trustee will recognize the holders of definitive certificates as
certificateholders under the Agreement. definitive certificates will be issued
in minimum denominations of $______, except that any beneficial ownership
represented by a Book-Entry Certificate in an amount less than $______
immediately prior to the issuance of a definitive certificate shall be issued in
a minimum denomination equal to the amount of the beneficial ownership.

PASS-THROUGH RATES

         The Pass-Through Rate for each class of Certificates (other than the
Class XS Certificates) is ____% per annum. The Pass-Through Rate applicable to
the calculation of the Interest Distribution Amount for the Class XS
Certificates for any distribution date is the rate per annum expressed as the
percentage equivalent of a fraction, the numerator of which is equal to (1) (A)
the amount of interest accrued on the mortgage loans for the immediately
preceding calendar month at the Net Mortgage Rate minus (B) the aggregate amount
of interest payable on the Certificates (other than the XS Certificates), and
the denominator of which is equal to (2) the Notional Amount of the Class XS
Certificates. The initial variable Pass-Through Rate for the Class IO
Certificates is approximately ______% per annum. INTEREST DISTRIBUTIONS

         Distributions on each distribution date will be made to the extent of
the Available Distribution Amount.

         Distributions in respect of interest will be made (1) on each
distribution date to the holders of the Senior Certificates and, on the first
distribution date, to the holders of the Residual Certificates, in an aggregate
amount equal to the Senior Interest Distribution Amount and (2) on each
distribution date to the holders of the Subordinate Certificates, in an
aggregate amount equal to the Subordinate Interest Distribution Amount, to the
extent of the portion of the Available Distribution Amount remaining after
distribution of the Senior Interest Distribution Amount and the Senior Principal
Distribution Amount.

         All distributions of interest will be based on a 360-day year
consisting of twelve 30-day months. Except as otherwise described in this
prospectus supplement, on any distribution date, distributions of the Interest
Distribution Amount for a class of Certificates will be made, to the extent
provided in this prospectus supplement, on a PARI PASSU basis, based on the
Certificate Principal Balance or Notional Amount, as applicable, of the
Certificates of each such class.


                                      S-48


         Distributions of the Subordinate Interest Distribution Amount on each
distribution date will be made first, to the holders of the Class B-1
Certificates, second to the holders of the Class B-2 Certificates, third to the
holders of the Class B-3 Certificates, and then to the holders of the remaining
classes of Subordinate Certificates, in each case to the extent of available
funds and in each case to the extent of the Interest Distribution Amount for
these Certificates for the distribution date.

PRINCIPAL DISTRIBUTIONS ON THE SENIOR CERTIFICATES

         Distributions in respect of principal will be made on each distribution
date to the holders of the class or classes of the Class A Certificates then
entitled to distributions in respect of principal, and on the first distribution
date to the holders of the Residual Certificates, in an aggregate amount equal
to the Senior Principal Distribution Amount.

         Holders of the Class A Certificates then entitled to distributions in
respect of principal will be entitled to receive on each distribution date, and
holders of the Residual Certificates will be entitled to receive on the first
distribution date, distributions allocable to principal in reduction of the
Certificate Principal Balances of the Class A Certificates, and on the first
distribution date the Residual Certificates, equal to the sum of the following:

         (1) the product of (A) the then applicable Senior Percentage and (B)
the aggregate of the following amounts:

         (1) the principal portion of all scheduled monthly payments on the
mortgage loans due during the related Due Period, whether or not received;

         (2) the principal portion of all proceeds received in respect of the
repurchase of a mortgage loan (or, in the case of a substitution, amounts
received representing a principal adjustment) as required by the Agreement
during the related Prepayment Period; and

         (3) the principal portion of all other unscheduled collections (other
than amounts described in clauses (2) and (3) hereof), including insurance
proceeds and liquidation proceeds, received during the related Prepayment
Period, to the extent applied as recoveries of principal;

         (2) the product of (A) the then applicable Senior Prepayment Percentage
and (B) the aggregate of all full and partial principal prepayments received
during the related Prepayment Period;

         (3) with respect to the net liquidation proceeds received and allocable
to principal of any mortgage loan that was finally liquidated during the related
Prepayment Period, the lesser of (a) the then applicable Senior Prepayment
Percentage multiplied by these net liquidation proceeds and (b) the then
applicable Senior Percentage multiplied by the Scheduled Principal Balance of
the mortgage loan at the time of liquidation; and

         (4) any amounts allocable to principal for any previous distribution
date (calculated pursuant to the three preceding clauses) that remain
undistributed, to the extent that any of these amounts are not attributable to
Realized Losses that were allocated to the Subordinate Certificates.

         Holders of the Class XS Certificates are not entitled to receive any
distributions allocable to principal.

         The Senior Percentage initially will equal approximately _____%, and
will in no event exceed 100%.


                                      S-49


         The disproportionate allocation of unscheduled payments in respect of
principal will have the effect of accelerating the amortization of the Senior
Certificates (other than the Class XS Certificates) while, in the absence of
Realized Losses, increasing the respective percentage interest in the principal
balance of the mortgage loans evidenced by the Subordinate Certificates.
Increasing the respective percentage interest in the trust fund of the
Subordinate Certificates relative to that of the Senior Certificates is intended
to preserve the availability of the subordination provided by the Subordinate
Certificates.

         If on any distribution date the allocation to the Class A Certificates
of full and partial principal prepayments and other amounts in the percentage
required above would reduce the aggregate outstanding Certificate Principal
Balance of the Class A Certificates below zero, the Senior Prepayment Percentage
for the distribution date will be limited to the percentage necessary to reduce
the aggregate Certificate Principal Balance of the Class A Certificates to zero.

         For purposes of all principal distributions described above and for
calculating the Senior Percentage, the Subordinate Percentage and the Senior
Prepayment Percentage, the applicable Certificate Principal Balance for any
distribution date shall be determined after the allocation of losses on the
mortgage loans in the mortgage pool to be made on such distribution date as
described under "--Allocation of Losses; Subordination" below.

PRIORITY OF PRINCIPAL DISTRIBUTIONS ON THE CLASS A CERTIFICATES AND THE RESIDUAL
CERTIFICATES

         Distributions of the Senior Principal Distribution Amount on the Class
A Certificates and the Residual Certificates on each distribution date will be
made as follows:

         (1) First, concurrently, to the holders of each class of the Residual
Certificates on the distribution date in ________ ____, an amount equal to the
entire Certificate Principal Balance thereof;

         (2) Second, to the holders of the Lockout Certificates, the Lockout
Distribution Percentage of the Senior Principal Distribution Amount, until the
Certificate Principal Balance thereof has been reduced to zero;

         (3) Third, to the holders of the Class A-1 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero;

         (4) Fourth, to the holders of the Class A-2 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero;

         (5) Fifth, to the holders of the Class A-3 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero;

         (6) Sixth, to the holders of the Class A-4 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero;

         (7) Seventh, to the holders of the Class A-5 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero;

         (8) Eighth, to the holders of the Lockout Certificates, until the
Certificate Principal Balance thereof has been reduced to zero.


                                      S-50


         Notwithstanding the foregoing priorities, upon the reduction of the
Certificate Principal Balances of the Subordinate Certificates to zero, the
priority of distributions of principal among the Class A Certificates will be
disregarded and distributions allocable to principal will be paid on each
succeeding distribution date to holders of the Class A Certificates, on a pro
rata basis, based on the Certificate Principal Balances thereof.

PRINCIPAL DISTRIBUTION ON THE SUBORDINATE CERTIFICATES

         Holders of each class of Subordinate Certificates will be entitled to
receive on each distribution date, to the extent of the portion of the Available
Distribution Amount remaining after distribution of the Senior Interest
Distribution Amount, the Senior Principal Distribution Amount and the
Subordinate Interest Distribution Amount, distributions allocable to principal
in reduction of the Certificate Principal Balances thereof equal to the sum of
the following:

         (1) the product of (A) the then applicable related Class B Percentage
and (B) the aggregate of the following amounts:

         (1) the principal portion of all scheduled monthly payments on the
mortgage loans due during the related Due Period, whether or not received;

         (2) the principal portion of all proceeds received in respect of the
repurchase of a mortgage loan (or, in the case of a substitution, amounts
received representing a principal adjustment) as required by the Agreement
during the related Prepayment Period; and

         (3) the principal portion of all other unscheduled collections (other
than amounts described in clauses (2) and (3) hereof), including insurance
proceeds and liquidation proceeds, received during the related Prepayment
Period, to the extent applied as recoveries of principal;

         (2) the portion allocable to such class of Subordinate Certificates, as
described below, of the product of (A) the then applicable Subordinate
Prepayment Percentage and (B) the aggregate of all full and partial principal
prepayments received during the related Prepayment Period;

         (3) the portion allocable to such class of Subordinate Certificates, as
described below, of net liquidation proceeds received and allocable to principal
of any mortgage loan that was finally liquidated during the related Prepayment
Period, to the extent of the amount, if any, by which such net liquidation
proceeds exceed the amount distributable to the Class A Certificates in respect
of such net liquidation proceeds pursuant to clause (3) of the definition of
Senior Principal Distribution Amount; and

         (4) any amounts allocable to principal for any previous distribution
date (calculated pursuant to the three preceding clauses) that remain
undistributed, to the extent that any of these amounts are not attributable to
Realized Losses that were allocated to classes of the Subordinate Certificates
bearing a higher numerical class designation.

         On any distribution date, the portion of (a) all principal prepayments
on the mortgage loans and (b) net liquidation proceeds allocable to principal of
any mortgage loan that was finally liquidated during the related Prepayment
Period, in each case not included in the Senior Principal Distribution Amount
will be allocated on a pro rata basis among the following classes of Subordinate
Certificates in proportion to the respective outstanding Certificate Principal
Balances thereof: (1) the Class B-1 Certificates; (2) the Class B-2
Certificates, if on such distribution date the aggregate percentage interest in
the trust fund evidenced by the Class B-2 Certificates, the Class B-3
Certificates, the Class B-4 Certificates, the Class B-5 Certificates and the
Class B-6 Certificates equals or exceeds ____% before giving effect to


                                      S-51


distributions on such distribution date; (3) the Class B-3 Certificates, if on
such distribution date the aggregate percentage interest in the trust fund
evidenced by the Class B-3 Certificates, the Class B-4 Certificates, the Class
B-5 Certificates and the Class B-6 Certificates equals or exceeds ____% before
giving effect to distributions on such distribution date; (4) the Class B-4
Certificates, if on such distribution date the percentage interest in the trust
fund evidenced by the Class B-4 Certificates, the Class B-5 Certificates and the
Class B-6 Certificates equals or exceeds ____% before giving effect to
distributions on such distribution date; (5) the Class B-5 Certificates, if on
such distribution date the percentage interest in the trust fund evidenced by
the Class B-5 Certificates and the Class B-6 Certificates equals or exceeds
____% before giving effect to distributions on such distribution date; and (6)
the Class B-6 Certificates, if on such distribution date the percentage interest
in the trust fund evidenced by the Class B-6 Certificates equals or exceeds
____% before giving effect to distributions on such distribution date.

         For purposes of all principal distributions described above and for
calculating the Subordinate Percentage, the applicable Certificate Principal
Balance for any distribution date shall be determined after the allocation of
losses on the mortgage loans in the mortgage pool to be made on such
distribution date as described under "--Allocation of Losses; Subordination"
below.

         As stated above under "--Principal Distributions on the Senior
Certificates", for each distribution date occurring prior to the distribution
date in ________ ____, the Senior Prepayment Percentage will equal 100%, and
until the earlier of such date and the date on which the Class A Certificates
are paid in full, no distributions based on principal prepayments or, in some
instances, net liquidation proceeds, on the mortgage loans will be distributed
to the Subordinate Certificates. Thereafter, unless the Certificate Principal
Balances of the Senior Certificates have been reduced to zero, the Subordinate
Prepayment Percentage may continue to be 0% or otherwise be disproportionately
small relative to the Subordinate Percentage. See "--Principal Distributions on
the Senior Certificates" in this prospectus supplement.

         Distributions of the Subordinate Principal Distribution Amount on each
distribution date will be made as follows: first to the holders of the Class B-1
Certificates, second to the holders of the Class B-2 Certificates, third to the
holders of the Class B-3 Certificates, and then to the holders of the remaining
classes of Subordinate Certificates, in each case to the extent of available
funds and in each case to the extent of the portion of the Subordinate Principal
Distribution Amount payable in respect of each such class of Subordinate
Certificates for such distribution date.

P&I ADVANCES

         Subject to the following limitations, the Master Servicer will be
obligated to advance or cause to be advanced on or before each distribution date
its own funds, or funds in the Certificate Account that are not included in the
Available Distribution Amount for such distribution date, in an amount equal to
the P&I Advances for such distribution date.

         P&I Advances are required to be made only to the extent they are deemed
by the Master Servicer to be recoverable from related late collections,
insurance proceeds or liquidation proceeds. The purpose of making P&I Advances
is to maintain a regular cash flow to the certificateholders, rather than to
guarantee or insure against losses. The Master Servicer will not be required to
make any P&I Advances with respect to reductions in the amount of the monthly
payments on the mortgage loans due to bankruptcy proceedings or the application
of the Relief Act.

         All P&I Advances will be reimbursable to the Master Servicer from late
collections, insurance proceeds and liquidation proceeds from the mortgage loan
as to which the unreimbursed P&I Advance was made. In addition, any P&I Advances
previously made in respect of any mortgage loan that are


                                      S-52


deemed by the Master Servicer to be nonrecoverable from related late
collections, insurance proceeds or liquidation proceeds may be reimbursed to the
Master Servicer out of any funds in the Certificate Account prior to the
distributions on the Certificates. In the event the Master Servicer fails in its
obligation to make any such advance, the Trustee will be obligated to make any
such advance, to the extent required in the Agreement.

TABLE OF FEES AND EXPENSES

         The following table indicates the fees and expenses to be paid from the
cash flows from the mortgage loans and other assets of the trust fund, while the
Certificates are outstanding.

         All fees are expressed in basis points, at an annualized rate, applied
to the outstanding aggregate principal balance of the mortgage loans.

                 ITEM                FEE                PAID FROM
       --------------------------  -------    ----------------------------------
       Master Servicing Fee(1)(2)   ___bp     Mortgage Loan Interest Collections
       Trustee Fee                  ___bp     Master Servicing Fee
       Servicer Fee                 ___bp     Master Servicing Fee

         (1)      Master servicing fee including trustee and certificate
                  registrar fees. The Master Servicer receives a single combined
                  fee that covers all of these functions. The Master Servicer
                  performs these functions.
         (2)      Master Servicer pays trustee and servicer fees out of its fee.
         (3)      The master servicing fee is paid on a first priority basis
                  from collections allocable to interest on the mortgage loans,
                  prior to distributions to certificateholders.


CREDIT ENHANCEMENT

         The credit enhancement provided for the benefit of the holders of the
offered certificates consists of subordination as described under "Description
of the Certificates--Allocation of Losses; Subordination" below.

         [Additional information with respect to credit enhancement providers,
required pursuant to Item 1114(b) of Regulation AB, will be provided if
applicable.]

         ALLOCATION OF LOSSES; SUBORDINATION

         Realized Losses (other than Excess Losses) will be allocated on any
distribution date as follows: first, to the Class B-6 Certificates; second, to
the Class B-5 Certificates; third, to the Class B-4 Certificates; fourth, to the
Class B-3 Certificates; fifth, to the Class B-2 Certificates; and sixth, to the
Class B-1 Certificates, in each case until the Certificate Principal Balance of
such class has been reduced to zero. Thereafter, such Realized Losses will be
allocated on any distribution date among the Class A Certificates on a pro rata
basis. Excess Losses will be allocated on any distribution date among all the
Certificates (other than the Class XS Certificates) on a pro rata basis. Any
allocation of a Realized Loss to a Certificate will be made by reducing the
Certificate Principal Balance thereof by the amount so allocated as of the
distribution date in the month following the calendar month in which such
Realized Loss was incurred.

         An allocation of a Realized Loss on a pro rata basis among two or more
classes of Certificates means an allocation to each such class of Certificates
on the basis of its then outstanding Certificate Principal Balance prior to
giving effect to distributions to be made on such distribution date.


                                      S-53


         With respect to any defaulted mortgage loan that is finally liquidated
through foreclosure sale, disposition of the related mortgaged property if
acquired on behalf of the certificateholders by deed-in-lieu of foreclosure or
otherwise, the amount of loss realized, if any, will equal the portion of the
unpaid principal balance remaining, if any, plus interest thereon through the
last day of the month in which such mortgage loan was finally liquidated, after
application of all amounts recovered (net of amounts reimbursable to the Master
Servicer for P&I Advances, Servicing Fees and Servicing Advances) towards
interest and principal owing on the mortgage loan. Such amount of loss realized
and any Special Hazard Losses, Fraud Losses and Bankruptcy Losses are referred
to in this prospectus supplement as "Realized Losses".

         The Special Hazard Amount, Fraud Loss Amount and Bankruptcy Amount may
be reduced or modified upon confirmation from Standard & Poor's and Fitch that
such reduction or modification will not adversely affect the then-current
ratings assigned to the offered certificates rated thereby. Such a reduction or
modification may adversely affect the coverage provided by the subordination
with respect to Special Hazard Losses, Fraud Losses and Bankruptcy Losses.

         In the event that Realized Losses are incurred that are covered by
subordination, such losses will be allocated to the most subordinate class of
Certificates then outstanding. The priorities for distribution of cash flows
described in this prospectus supplement, in some circumstances, may result in
cash flow shortfalls to any class of Subordinate Certificates even if it is not
the most subordinate class of Certificates then outstanding; however, the
interest portion of any such shortfall would be distributable as unpaid Interest
Distribution Amount on future distribution dates as cash flows allow, to the
extent of available funds, and the principal portion of any such shortfall would
not result in a reduction of the Certificate Principal Balance of such class. In
such event, the percentage interest represented by such class would increase
relative to the respective Certificate Principal Balances of the more
subordinate classes of Certificates. With respect to the most subordinate class
of the Certificates outstanding at the time any Realized Loss is incurred, the
total amount of the Realized Loss allocated to such class may be greater than
the concurrent reduction in the Certificate Principal Balance thereof because
such reduction will not reflect any undistributed Interest Distribution Amount
on such class. Such undistributed Interest Distribution Amount on the most
subordinate class of the Certificates outstanding will not be distributable on
any future distribution date. As a result, it is possible that the total amount
of Realized Losses that may be allocated to any class of Subordinate
Certificates may exceed the initial Certificate Principal Balance thereof.

         In order to maximize the likelihood of distribution in full of the
Senior Interest Distribution Amount and the Senior Principal Distribution
Amount, on each distribution date, holders of Senior Certificates have a right
to distributions of the Available Distribution Amount that is prior to the
rights of the holders of the Subordinate Certificates, to the extent necessary
to satisfy the Senior Interest Distribution Amount and the Senior Principal
Distribution Amount.

         The application of the Senior Prepayment Percentage (when it exceeds
the Senior Percentage) to determine the Senior Principal Distribution Amount
will accelerate the amortization of the Class A Certificates relative to the
actual amortization of the mortgage loans. To the extent that the Class A
Certificates are amortized faster than the mortgage loans, in the absence of
offsetting Realized Losses allocated to the Subordinate Certificates, the
percentage interest evidenced by the Class A Certificates in the trust fund will
be decreased (with a corresponding increase in the percentage interest in the
trust fund evidenced by the Subordinate Certificates), thereby increasing,
relative to their respective Certificate Principal Balances, the subordination
afforded the Senior Certificates by the Subordinate Certificates.

         DERIVATIVE CONTRACTS

         On the Closing Date, either the Sponsor will assign to the Depositor,
and the Depositor will assign to the Issuing Entity for the benefit of the
Certificates, its rights under the Derivative Contracts, or the Sponsor will
cause the Issuing Entity to enter into the Derivative Contracts with the
Derivative Counterparty. The Derivative Contracts will contain a Swap Agreement
Fixed Rate and provide for the calculation of One-Month LIBOR. The Derivative
Contracts consists of ___________ swap agreement, where net payments will be
made (a) to the Issuing Entity, if One-Month LIBOR exceeds the Swap Agreement
Fixed Rate, and (b) to the Derivative Counterparty, to the extent such Swap
Agreement Fixed Rate exceeds One-Month LIBOR.

         Payments will be made to the Derivative Contracts based on a notional
balance in accordance with the schedule set forth in the Derivative Contracts.
The amount of the notional balance on which calculations are based on any
payment date with respect to the swap agreement will be the lesser of (a) the
balance in the related schedule and (b) a percentage of the aggregate
Certificate Principal Balance of the Certificates immediately prior to the
related payment date.

         On each payment date, the Trustee will determine the total amount
payable to the Issuing Entity and the total amount payable to the Derivative
Counterparty under the Derivative Contracts. The Trustee will determine whether
a net payment is due to the Issuing Entity or from the Derivative Counterparty
and will collect or make such payment, as applicable. Payments due by the
Issuing Entity under the Derivative Contracts will be made prior to payments on
the Certificates.

         The Derivative Counterparty, or the guarantor thereof making payments
to The Issuing Entity is, as of the Closing Date, rated" at least "AA-" (or its
equivalent) by two of S&P, Moody's or Fitch Ratings.

         The Swap Agreement Fixed Rates and scheduled principal balances of the
_________ swap agreement will pay in accordance tables below; provided, that the
scheduled principal balances may from time to time be less than the amount in
their actual schedules based on the aggregate Certificate Principal Balances of
the Certificates as described above:


                                  SCHEDULED PRINCIPAL        SWAP AGREEMENT

                                      S-55



         After the payment date in _____________, the first swap agreement will
terminate without termination payments by either party.

         [Additional tables added as necessary]

         [Additional information with respect to certain derivative instruments,
required pursuant to Item 1115 of Regulation AB, will be provided if
applicable.]

THE MASTER SERVICER AND THE SERVICERS

GENERAL

         Impac Funding Corporation, referred to in this prospectus supplement as
Impac Funding Corporation or the Master Servicer, will act as the Master
Servicer of the mortgage loans pursuant to the Pooling and Servicing Agreement,
referred to herein as the Agreement, dated as of the Cut-off Date, among the
Depositor, the Sponsor, the Master Servicer and the Trustee.

         Primary servicing of the mortgage loans will be provided for in
accordance with the Pooling and Servicing Agreement or similar agreements, which
are collectively referred to in this prospectus supplement as the Servicing
Agreements. Each of the Servicing Agreements will be assigned to the trust
pursuant to various assignment, assumption and recognition agreements among the
related Servicer, the Sponsor and the Trustee on behalf of the
Certificateholders; provided, however, that the Sponsor will retain the right to
enforce the representations and warranties made by the Servicers with respect to
the related mortgage loans against them. In the event of a default by a Servicer
under the related Servicing Agreement, the Master Servicer will be required to
enforce any remedies against the Servicer, and shall either find a successor
Servicer or shall assume primary servicing obligations for the related mortgage
loans itself.

         The Servicer or the Master Servicer, directly or through subservicers,
as the case may be, will make reasonable efforts to collect all payments called
for under the loans and will, consistent with the related servicing agreement
and any applicable insurance policy, FHA insurance or other credit enhancement,
follow the collection procedures that are normal and usual in its general loan
servicing activities for assets that are comparable to the loans. Consistent
with the previous sentence, the Servicer or the Master Servicer may, in its
discretion, waive any prepayment charge in connection with the prepayment of a
loan or extend the due dates for payments due on a mortgage note, provided that
the insurance coverage for the loan or any coverage provided by any alternative
credit enhancement will not be adversely affected by the waiver or extension.
The Master Servicer or Servicer may also waive or


                                      S-58


modify any term of a loan so long as the Master Servicer or Servicer has
determined that the waiver or modification is not materially adverse to any
securityholders, taking into account any estimated loss that may result absent
that action.

         In instances in which a loan is in default, or if default is reasonably
foreseeable, and if determined by the Master Servicer or Servicer to be in the
best interests of the related securityholders, the Master Servicer or Servicer
may engage, either directly or through subservicers, in a wide variety of loss
mitigation practices including waivers, modifications, payment forbearances,
partial forgiveness, entering into repayment schedule arrangements, and
capitalization of arrearages rather than proceeding with foreclosure or
repossession, if applicable. In making that determination, the estimated
Realized Loss that might result if the loan were liquidated would be taken into
account. Modifications may have the effect of, among other things, reducing the
loan rate, forgiving payments of principal, interest or other amounts owed under
the mortgage loan or contract, such as taxes or insurance premiums, extending
the final maturity date of the loan, capitalizing delinquent interest and other
amounts owed under the mortgage loan or contract, or any combination of these or
other modifications. Any modified loan may remain in the related trust, and the
reduction in collections resulting from a modification may result in reduced
distributions of interest or principal on, or may extend the final maturity of,
one or more classes of the related securities.

         The Servicers will be responsible for the servicing of the mortgage
loans covered by the related Servicing Agreement, and the Master Servicer will
be required to monitor their performance. All collections of principal and
interest on any mortgage loans, including but not limited to Principal
Prepayments, Insurance Proceeds, Liquidation Proceeds (less amounts reimbursable
to the applicable Servicer out of Liquidation Proceeds in accordance with the
applicable Servicing Agreement), the Repurchase Price for any mortgage loans
repurchased, and advances made from the Servicer's own funds (less the servicing
fee) will be deposited in a Protected Account, held by a designated depository
institution and segregated on the books of such institution in the name of the
Trustee for the benefit of Certificateholders. Amounts on deposit in a Protected
Account may be invested in Permitted Investments in the name of the Trustee for
the benefit of Certificateholders and, except as provided in the preceding
paragraph, not commingled with any other funds. Such Permitted Investments shall
mature, or shall be subject to redemption or withdrawal, no later than the date
on which such funds are required to be withdrawn for deposit in the Master
Servicer Collection Account, and shall be held until required for such deposit.
The income earned from Permitted Investments made shall be paid to the related
Servicer under the applicable Servicing Agreement, and the risk of loss of
moneys required to be distributed to the Certificateholders resulting from such
investments shall be borne by and be the risk of the related Servicer. The
related Servicer (to the extent provided in the Servicing Agreement) shall
deposit the amount of any such loss in the Protected Account within two Business
Days of receipt of notification of such loss but not later than the second
Business Day prior to the Distribution Date on which the moneys so invested are
required to be distributed to the Certificateholders. On the date specified in
the related Servicing Agreement, the related Servicer will withdraw or cause to
be withdrawn from the applicable Protected Accounts and any other permitted
accounts and will remit to the Master Servicer for deposit in the Master
Servicer Collection Account the Available Funds. SEE "DESCRIPTION OF THE
SECURITIES-CERTIFICATE ACCOUNT" IN THE PROSPECTUS.

                              PERMITTED INVESTMENTS

         Any institution maintaining a custodial account shall at the direction
of the Master Servicer invest the funds in such account in Permitted
Investments, each of which shall mature not later than (i) the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to the Pooling and Servicing Agreement, if a Person
other than the Trustee is the obligor thereon, and (ii) no later than the date
on which such funds are required to be withdrawn from such account pursuant to
the Pooling and Servicing Agreement, if the Trustee is the obligor thereon and
shall not be sold or disposed of prior to its maturity. All income and gain
realized from any such investment as well as any interest earned on deposits in
a custodial account shall be for the benefit of the Master Servicer. The Master
Servicer shall deposit in a custodial account an amount equal to the amount of
any loss incurred in respect of any such investment immediately upon realization
of such loss without right of reimbursement.

         Any one or more of the following obligations or securities held in the
name of the Trustee for the benefit of the Certificateholders will be considered
a Permitted Investment:


                                      S-64


         (i) obligations of or guaranteed as to principal and interest by the
United States or any agency or instrumentality thereof when such obligations are
backed by the full faith and credit of the United States;

         (ii) repurchase agreements on obligations specified in clause (i)
maturing not more than one month from the date of acquisition thereof, provided
that the unsecured obligations of the party agreeing to repurchase such
obligations are at the time rated by each Rating Agency in its highest
short-term rating available;

         (iii) federal funds, certificates of deposit, demand deposits, time
deposits and bankers' acceptances (which shall each have an original maturity of
not more than 90 days and, in the case of bankers' acceptances, shall in no
event have an original maturity of more than 365 days or a remaining maturity of
more than 30 days) denominated in United States dollars of any U.S. depository
institution or trust company incorporated under the laws of the United States or
any state thereof or of any domestic branch of a foreign depository institution
or trust company; provided that the debt obligations of such depository
institution or trust company (or, if the only Rating Agency is Standard &
Poor's, in the case of the principal depository institution in a depository
institution holding company, debt obligations of the depository institution
holding company) at the date of acquisition thereof have been rated by each
Rating Agency in its highest short-term rating available; and provided further
that, if the only Rating Agency is Standard & Poor's and if the depository or
trust company is a principal subsidiary of a bank holding company and the debt
obligations of such subsidiary are not separately rated, the applicable rating
shall be that of the bank holding company; and, provided further that, if the
original maturity of such short-term obligations of a domestic branch of a
foreign depository institution or trust company shall exceed 30 days, the
short-term rating of such institution shall be A-1+ in the case of Standard &
Poor's if Standard & Poor's is the Rating Agency;

         (iv) commercial paper (having original maturities of not more than 365
days) of any corporation incorporated under the laws of the United States or any
state thereof which on the date of acquisition has been rated by Moody's and
Standard & Poor's in their highest short-term ratings available; provided that
such commercial paper shall have a remaining maturity of not more than 30 days;

         (v) a money market fund or a qualified investment fund rated by Moody's
in its highest long-term ratings available and rated AAAm or AAAm-G by Standard
& Poor's, including any such funds for which ___________ or any affiliate
thereof serves as an investment advisor, manager, administrator, shareholder,
servicing agent, and/or custodian or sub-custodian; and

         (vi) other obligations or securities that are acceptable to each Rating
Agency as a Permitted Investment hereunder and will not reduce the rating
assigned to any Class of Certificates by such Rating Agency below the lower of
the then-current rating or the rating assigned to such Certificates as of the
Closing Date by such Rating Agency, as evidenced in writing;

provided, however, that no instrument shall be a Permitted Investment if it
represents, either (1) the right to receive only interest payments with respect
to the underlying debt instrument or (2) the right to receive both principal and
interest payments derived from obligations underlying such instrument and the
principal and interest payments with respect to such instrument provide a yield
to maturity greater than 120% of the yield to maturity at par of such underlying
obligations.

                         FEDERAL INCOME TAX CONSEQUENCES

         An election will be made to treat the trust fund as a REMIC for federal
income tax purposes. Upon the issuance of the offered certificates, Thacher
Proffitt & Wood LLP, counsel to the depositor, will


                                      S-65


deliver its opinion generally to the effect that, assuming compliance with all
provisions of the Agreement, for federal income tax purposes, the REMIC will
qualify as a REMIC under Sections 860A through 860G of the Code.

         For federal income tax purposes, (1) the Class R Certificates will be
the sole class of "residual interests" in the REMIC and (2) the Senior
Certificates and the Subordinate Certificates will evidence the "regular
interests" in, and will be treated as debt instruments of, the REMIC. See
"Federal Income Tax Consequences--REMIC--Classification of REMICs" in the
prospectus.

         For federal income tax reporting purposes, the Class XS Certificates
will, and the Class A Certificates, the Class B-1 Certificates, the Class B-2
Certificates and the Class B-3 Certificates will not, be treated as having been
issued with original issue discount. The prepayment assumption that will be used
in determining the rate of accrual of original issue discount, premium and
market discount, if any, for federal income tax purposes will be based on the
assumption that, subsequent to the date of any determination, the mortgage loans
will prepay at a rate equal to ____% of the prepayment assumption. No
representation is made that the mortgage loans will prepay at that rate or at
any other rate. See "Federal Income Tax Consequences--REMICs--Taxation of Owners
of REMIC Regular Certificates--Original Issue Discount" in the prospectus.

         The IRS has issued OID Regulations under Sections 1271 to 1275 of the
Code generally addressing the treatment of debt instruments issued with original
issue discount. Purchasers of the Class XS Certificates should be aware that the
OID Regulations do not adequately address some issues relevant to, or are not
applicable to, securities such as the Class XS Certificates. In addition, there
is considerable uncertainty concerning the application of the OID Regulations to
REMIC Regular Certificates that provide for payments based on a variable rate
such as the Class XS Certificates. Prospective purchasers of the Class XS
Certificates are advised to consult their tax advisors concerning the tax
treatment of such Certificates.

         If the method of computing original issue discount described in the
prospectus results in a negative amount for any period with respect to any
certificateholders (in particular, the holders of the Class XS Certificates),
the amount of original issue discount allocable to such period would be zero,
and such certificateholders will be permitted to offset such amounts only
against the respective future income (if any) from such Certificate. Although
uncertain, a certificateholders may be permitted to deduct a loss to the extent
that his or her respective remaining basis in such Certificate exceeds the
maximum amount of future payments to which such certificateholders is entitled,
assuming no further prepayments of the mortgage loans. Although the matter is
not free from doubt, any such loss might be treated as a capital loss.

         The OID Regulations suggest that original issue discount with respect
to securities such as the Class XS Certificates that represent multiple
uncertificated REMIC regular interests, in which ownership interests will be
issued simultaneously to the same buyer should be computed on an aggregate
method. In the absence of further guidance from the IRS, original issue discount
with respect to the uncertificated regular interests represented by the Class XS
Certificates will be reported to the IRS and the certificateholders on an
aggregate method based on a single overall constant yield and the prepayment
assumption stated above, treating all such uncertificated regular interests as a
single debt instrument as set forth in the OID Regulations.

         The OID Regulations in some circumstances permit the holder of a debt
instrument to recognize original issue discount under a method that differs from
that of the issuer. Accordingly, it is possible that holders of offered
certificates issued with original issue discount may be able to select a method
for recognizing original issue discount that differs from that used in preparing
reports to certificateholders


                                      S-66


and the IRS. Prospective purchasers of offered certificates issued with original
issue discount are advised to consult their tax advisors concerning the tax
treatment of such Certificates in this regard.

         Some Classes of Certificates may be treated for federal income tax
purposes as having been issued with a premium. Certificateholders may elect to
amortize such premium under a constant yield method in which case such
amortizable premium will generally be allocated among the interest payments on
such Certificates and will be applied as an offset against such interest
payments. See "Federal Income Tax Consequences--REMICs--Taxation of Owners of
REMIC Regular Certificates--Premium" in the prospectus.

         The offered certificates will be treated as assets described in Section
7701(a)(19)(C) of the Code and "real estate assets" under Section 856(c)(4)(A)
of the Code, generally in the same proportion that the assets in the related
trust fund would be so treated. In addition, interest on the offered
certificates will be treated as "interest on obligations secured by mortgages on
real property" under Section 856(c)(3)(B) of the Code, generally to the extent
that the offered certificates are treated as "real estate assets" under Section
856(c)(4)(A) of the Code. The offered certificates (other than the Residual
Certificates) also will be treated as "qualified mortgages" under Section
860G(a)(3) of the Code. See "Federal Income Tax Consequences--REMICs--
Characterization of Investments in REMIC Certificates" in the prospectus.

         It is not anticipated that the REMIC will engage in any transactions
that would subject it to the prohibited transactions tax as defined in Section
860F(a)(2) of the Code, the contributions tax as defined in Section 860G(d) of
the Code or the tax on net income from foreclosure property as defined in
Section 860G(c) of the Code. However, in the event that any such tax is imposed
on the REMIC, such tax will be borne (1) by the Trustee, if the Trustee has
breached its obligations with respect to REMIC compliance under the Agreement,
(2) by the Master Servicer, if the Master Servicer has breached its obligations
with respect to REMIC compliance under the Agreement and (3) otherwise by the
trust fund, with a resulting reduction in amounts otherwise distributable to
holders of the related offered certificates. See "Description of the
Certificates-- General" and "Federal Income Tax Consequences--REMICs--Prohibited
Transactions Tax and Other Taxes" in the prospectus.

         The responsibility for filing annual federal information returns and
other reports will be borne by the Trustee. See "Federal Income Tax
Consequences--REMICs--Reporting and Other Administrative Matters" in the
prospectus.

         For further information regarding the federal income tax consequences
of investing in the offered certificates, see "Federal Income Tax
Consequences--REMICs" in the prospectus.

SPECIAL TAX CONSIDERATIONS APPLICABLE TO RESIDUAL CERTIFICATES

         The IRS has issued REMIC regulations under the provisions of the
Internal Revenue Code that significantly affect holders of Residual
Certificates. The REMIC Regulations will impose restrictions on the transfer or
acquisition of residual interests, including the Residual Certificates. In
addition, the REMIC Regulations contain restrictions that apply to the transfer
of "noneconomic" residual interests to United States persons. The REMIC
Regulations also provide that transfers of a Residual Certificate to a
non-United States person will be disregarded for tax purposes in some cases.
Transfers of the Residual Certificates to such persons are, however, prohibited
under the Agreement. See "Federal Income Tax Consequences--REMICs--Taxation of
Owners of REMIC Residual Certificates--Noneconomic REMIC Residual Certificates"
in the prospectus and "ERISA Considerations" and "Description of the
Certificates--Restrictions on Transfer of the Residual Certificates" in this
prospectus supplement for additional restrictions on transfer of the Residual
Certificates.


                                      S-67


         The REMIC Regulations also provide that a transfer to a United States
person of "noneconomic" residual interests will be disregarded for all federal
income tax purposes, and that the purported transferor of "noneconomic" residual
interests will continue to remain liable for any taxes due with respect to the
income on such residual interests, unless "no significant purpose of the
transfer was to impede the assessment or collection of tax". Based on the REMIC
Regulations, the Residual Certificates will constitute noneconomic residual
interests during some or all of their terms for purposes of the REMIC
Regulations and, accordingly, unless no significant purpose of a transfer is to
impede the assessment or collection of tax, transfers of the Residual
Certificates may be disregarded and purported transferors may remain liable for
any taxes due with respect to the income on the Residual Certificates. All
transfers of the Residual Certificates will be subject to restrictions under the
terms of the Agreement that are intended to reduce the possibility of any such
transfer being disregarded to the extent that the Residual Certificates
constitute noneconomic residual interests.

         The holders of the Residual Certificates will be required to report
taxable income and pay tax with respect to the early accrual periods of the
REMIC's term that significantly exceeds the amount of cash distributions
received by such holders from the REMIC with respect to such periods.
Furthermore, the tax on such income will exceed the cash distributions with
respect to such periods. Consequently, holders of Residual Certificates should
have other sources of funds sufficient to pay any federal income taxes due in
the earlier years of the REMIC as a result of their ownership of Class R
Certificates. In addition, the required inclusion of this amount of taxable
income during the REMIC's earlier accrual periods and the deferral of
corresponding tax losses or deductions until later accrual periods or until the
ultimate sale or disposition of a Residual Certificate (or possibly later under
the "wash sale" rules of Section 1091 of the Code) may cause the after-tax rate
of return of a holder of a Residual Certificate to be zero or negative even
where such holders' pre-tax rate of return is positive. That is, on a present
value basis, the resulting tax liabilities of a holder of a Residual Certificate
will substantially exceed the sum of any tax benefits and the amount of any cash
distributions on such Residual Certificates over their life.

         An individual, trust or estate that holds (whether directly or
indirectly through a pass-through entity) a Residual Certificate may have
significant additional gross income with respect to, but may be subject to
limitations on the deductibility of, servicing and trustee's fees and other
administrative expenses properly allocable to the REMIC in computing such
holder's regular tax liability and will not be able to deduct these fees or
expenses to any extent in computing such holder's alternative minimum tax
liability. See "Federal Income Tax Consequences--REMICs--Taxation of Owners of
REMIC Residual Certificates--Pass Through of Miscellaneous Itemized Deductions"
in the prospectus.

         Potential investors in Residual Certificates should also be aware that
under the terms of the Agreement, the holders of the largest Percentage Interest
in the Residual Certificates shall, by their acceptance of such Certificates,
agree to irrevocably appoint the Trustee as their agent to perform all of the
duties of the tax matters person for the REMIC.

         Purchasers of the Residual Certificates are strongly advised to consult
their own tax advisors as to the economic and tax consequences of investment in
the Residual Certificates.

         For further information regarding the federal income tax consequences
of investing in the Residual Certificates, see "Yield on the
Certificates--Additional Yield Considerations Applicable Solely to the Residual
Certificates" in this prospectus supplement and "Federal Income Tax
Consequences--REMICs--Taxation of Owners of REMIC Residual Certificates" in the
prospectus.

of investing in the offered certificates, see "Federal Income Tax
Consequences--REMICs" in the prospectus.

                             METHOD OF DISTRIBUTION

         Subject to the terms and conditions set forth in the underwriting
agreement, dated _________ __, ____, the depositor has agreed to sell, and the
Underwriter has agreed to purchase the offered certificates. The Underwriter is
obligated to purchase all offered certificates of the respective classes offered
by this prospectus supplement if it purchases any. The Underwriter is an
affiliate of the depositor.

         Distribution of the offered certificates will be made from time to time
in negotiated transactions or otherwise at varying prices to be determined at
the time of sale. Proceeds to the depositor from the sale of the offered
certificates, before deducting expenses payable by the depositor, will be
approximately _________% of the aggregate initial Certificate Principal Balance
of the offered certificates, plus accrued interest on the offered certificates.
In connection with the purchase and sale of the offered certificates, the
Underwriter may be deemed to have received compensation from the depositor in
the form of underwriting discounts.

         The offered certificates are offered subject to receipt and acceptance
by the Underwriter, to prior sale and to the Underwriter's right to reject any
order in whole or in part and to withdraw, cancel or modify the offer without
notice. It is expected that delivery of the Book-Entry Certificates will be made
through the facilities of DTC, and that delivery of each other class of offered
certificates and the Residual Certificates will be made at the offices of the
Underwriter, [Address], in each case, on or about the Closing Date.

         The underwriting agreement provides that the depositor will indemnify
the Underwriter against certain civil liabilities, including liabilities under
the Securities Act of 1933, as amended, or will contribute to payments the
Underwriter may be required to make in respect thereof.

                                SECONDARY MARKET

         There can be no assurance that a secondary market for the offered
certificates will develop or, if it does develop, that it will continue. The
primary source of information available to investors concerning the offered
certificates will be the monthly statements discussed in the prospectus under
"Description of the Securities--Reports to Certificateholders", which will
include information as to the outstanding principal balance of the offered
certificates and the status of the applicable form of credit enhancement. There
can be no assurance that any additional information regarding the offered
certificates will be available through any other source. In addition, the
depositor is not aware of any source through which price information about the
offered certificates will be generally available on an ongoing basis. The
limited nature of information regarding the offered certificates may adversely
affect the liquidity of the offered certificates, even if a secondary market for
the offered certificates becomes available.

                                 LEGAL OPINIONS

         Legal matters relating to the offered certificates will be passed upon
for the depositor and the Underwriter by Thacher Proffitt & Wood LLP, New York,
New York.

                                LEGAL PROCEEDINGS

         [There are no material legal proceedings pending against the Sponsor,
the Depositor, the Trustee, The Issuing Entity, the Master Servicer, [any
affiliated Servicer, any 20% concentration unaffiliated Servicer, any 20%

of any of the foregoing transaction parties is subject, that are material to the
Certificateholders. No legal


                                      S-69


proceedings against any of the foregoing transaction parties is known to be
contemplated by governmental authorities, that are material to the
Certificateholders.]

              AFFILIATIONS, RELATIONSHIPS AND RELATED TRANSACTIONS

         [There are no affiliations between the Sponsor, the Depositor or the
Issuing Entity and any of the Master Servicer, [any affiliated Servicer, any 20%
concentration unaffiliated Servicer], the Trustee, [any 10% concentration
Originator], [any credit enhancement provider or derivatives counterparty], the
Custodians. There are no affiliations among the Master Servicer, [any affiliated
Servicer, any 20% concentration unaffiliated Servicer], the Trustee, [any 10%
concentration Originator], [any credit enhancement provider or derivatives
counterparty], the Custodians. There are currently no business relationships,
agreements, arrangements, transactions or understandings between (a) the
Sponsor, the Depositor or the Issuing Entity and (b) any of the parties referred
to in the preceding sentence, or any of their respective affiliates, that were
entered into outside the normal course of business or that contain terms other
than would be obtained in an arm's length transaction with an unrelated third
party and that are material to the investor's understanding of the Certificates,
or that relate to the Certificates or the pooled assets. No such business
relationship, agreement, arrangement, transaction or understanding has existed
during the past two years.]

                                     RATINGS

         It is a condition to the issuance of the Certificates that the Class A
Certificates and the Residual Certificates be rated "AAA" by _________________
("_____") and "AAA" by ____________ ("____"), that the Class B-1 Certificates be
rated at least "AA" by _________ and at least "AA" by _______, that the Class
B-2 Certificates be rated at least "A" by _________ and at least "A" by
________, and that the Class B-3 Certificates be rated at least "BBB" by
__________.

         The ratings of _________ and ________ assigned to mortgage pass-through
certificates address the likelihood of the receipt by certificateholders of all
distributions to which the certificateholders are entitled. The rating process
addresses structural and legal aspects associated with the Certificates,
including the nature of the underlying mortgage loans. The ratings assigned to
mortgage pass-through certificates do not represent any assessment of the
likelihood that principal prepayments will be made by the mortgagors or the
degree to which the rate and timing principal prepayments will differ from that
originally anticipated. The ratings do not address the possibility that
certificateholders might suffer a lower than anticipated yield due to non-credit
events or that the holders of the Class XS Certificates may fail to recover
fully their initial investment. In addition, the ratings on the Residual
Certificates do not address the likelihood of receipt by the holders of the
Residual Certificates of any amounts in excess of their initial Certificate
Balance thereof and interest thereon.

         A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning rating organization. Each security rating should be evaluated
independently of any other security rating. In the event that the ratings
initially assigned to the offered certificates are subsequently lowered for any
reason, no person or entity is obligated to provide any additional credit
support or credit enhancement with respect to the offered certificates.

         The depositor has not requested that any rating agency rate any class
of the offered certificates other than as stated above. However, there can be no
assurance as to whether any other rating agency will rate any class of the
offered certificates, or, if it does, what rating would be assigned by any other
rating agency. A rating on any class of the offered certificates by another
rating agency, if assigned at all, may be lower than the ratings assigned to the
offered certificates as stated above.


                                      S-70


         The rating agencies have stated that it is their standard policy to
monitor ratings on publicly offered securities for which a rating has been
provided, as to each rating agency rating each class of Offered Certificates in
accordance with the rating agencies' particular surveillance policies, unless
the issuer requests a rating without surveillance. A rating agency will monitor
the rating it issues on an ongoing basis and may update the rating after
conducting its regular review of the issuer's creditworthiness or after
conducting a review of the status of the rating upon becoming aware of any
information that might reasonably be expected to result in a change of rating.
The Depositor has not requested that any rating agency not monitor their ratings
of the Offered Certificates, and the Depositor has not requested that any rating
agency use any monitoring procedures other than their standard monitoring
procedures.

                                LEGAL INVESTMENT

         The Senior Certificates and the Class B-1 Certificates will constitute
"mortgage related securities" for purposes of SMMEA for so long as they are
rated not lower than the second highest rating category by a Rating Agency (as
defined in the prospectus) and, as such, will be legal investments for entities
to the extent provided in SMMEA. SMMEA, however, provides for state limitation
on the authority of these entities to invest in "mortgage related securities"
provided that restrictive legislation by the state was enacted prior to October
3, 1991. Some states have enacted legislation which overrides the preemption
provisions of SMMEA. The Class B-2 Certificates and the Class B-3 Certificates
will not constitute "mortgage related securities" for purposes of SMMEA.

         The depositor makes no representations as to the proper
characterization of any class of offered certificates for legal investment or
other purposes, or as to the ability of particular investors to purchase any
class of offered certificates under applicable legal investment restrictions.
These uncertainties may adversely affect the liquidity of any class of offered
certificates. Accordingly, all institutions whose investment activities are
subject to legal investment laws and regulations, regulatory capital
requirements or review by regulatory authorities are encouraged to consult with
their legal advisors in determining whether and to what extent any class of
offered certificates constitutes a legal investment or is subject to investment,
capital or other restrictions.

         See "Legal Investment" in the prospectus.


                              AVAILABLE INFORMATION

                              ERISA CONSIDERATIONS

         A fiduciary of any Plan and any person investing Plan Assets of any
Plan should carefully review with its legal advisors whether the purchase, sale
or holding of certificates will give rise to a prohibited transaction under
ERISA or Section 4975 of the Code.

         The U.S. Department of Labor has issued an Exemption, as described
under "ERISA Considerations" in the prospectus, to the Underwriter. The
Exemption generally exempts from the application of certain of the prohibited
transaction provisions of Section 406 of ERISA, and the excise taxes imposed on
such prohibited transactions by Section 4975(a) and (b) of the Code and Section
502(i) of ERISA, transactions relating to the purchase, sale and holding of
pass-through certificates rated at least "BBB-" (or its equivalent) by the
Exemption Rating Agencies at the time of purchase and underwritten by the
Underwriter, such as the offered certificates, and the servicing and operation
of asset pools, such as the mortgage pool, provided that the conditions of the
Exemption are satisfied. The purchase of the offered certificates by, on behalf
of or with the Plan Assets of any Plan may qualify for exemptive relief under
the Exemption, as amended and as currently in effect. However, the Exemption
contains a number of conditions which must be met for the Exemption, as amended,
to apply (as described in the prospectus), including the requirement that any
such Plan must be an "accredited investor" as defined in Rule 501(a)(1) of
Regulation D of the Securities and Exchange Commission under the Securities Act
of 1933, as amended. A fiduciary of a Plan contemplating purchasing an offered
certificate must make its own determination that the conditions set forth in the
Exemption, as amended, will be satisfied with


                                      S-72


respect to such certificates, including the requirement that the rating on a
particular class of certificates be "BBB-" or higher at the time of purchase.

         Each beneficial owner of a Subordinate Certificate or any interest
therein must represent that either (i) it is not a Plan or investing with assets
of Plan, (ii) it has acquired and is holding such certificate in reliance on the
Exemption, and that it understands that there are certain conditions to the
availability of the Exemption, including that such certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by S&P, Fitch or
Moody's Investors Service, Inc., and such certificate is so rated or (iii) (1)
it is an insurance company, (2) the source of funds used to acquire or hold the
certificate or interest therein is an "insurance company general account," as
such term is defined in Prohibited Transaction Class Exemption ("PTCE") 95-60,
and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

         Any fiduciary or other investor of Plan Assets that proposes to acquire
or hold the offered certificates on behalf of or with Plan Assets of any Plan
should consult with its counsel with respect to the application of the fiduciary
responsibility provisions of ERISA and the prohibited transaction provisions of
the ERISA and the Code to the proposed investment. SEE "ERISA CONSIDERATIONS" IN
THE PROSPECTUS.

         The sale of any class of offered certificates to a Plan is in no
respect a representation by the depositor, the Trustee or the Underwriter that
such an investment meets all relevant legal requirements with respect to
investments by Plans generally or any particular Plan, or that such an
investment is appropriate for Plans generally or any particular Plan.

common law trust. Impac Secured Assets Trust ___-__ will issue ___ classes of
certificates representing the trust.

SEE "DESCRIPTION OF THE CERTIFICATES" IN THIS PROSPECTUS SUPPLEMENT.

THE MORTGAGE LOANS

The trust will contain approximately _____ conventional, one- to four-family,
fixed-rate mortgage loans secured by first liens and second liens on residential
real properties. The mortgage loans have an aggregate principal balance of
approximately $___________ as of _______ __, ____.

[Approximately ___% of the mortgage loans are "sub-prime" mortgage loans.]

[If the trust contains mortgage securities, the mortgage securities will be
specifically identified by reference to the transaction(s) pursuant to which
such mortgage securities were issued, the percentage interest represented by
such mortgage securities and the characteristics of such mortgage securities
will be described in detail. In addition, the assets underlying the mortgage
securities will be described in detail.]

FOR ADDITIONAL INFORMATION REGARDING THE MORTGAGE LOANS, SEE "THE MORTGAGE POOL"
IN THIS PROSPECTUS SUPPLEMENT.

REMOVAL AND SUBSTITUTION OF A MORTGAGE LOAN

The trustee will acknowledge the sale, transfer and assignment of the trust fund
to it by the depositor and receipt of, subject to further review and the
exceptions, the mortgage loans. If the trustee finds that any mortgage loan is
defective on its face due to a breach of the representations and warranties with
respect to that loan made in the transaction agreements, the trustee shall
promptly notify the sponsor of such defect. The sponsor must then correct or
cure any such defect within 90 days from the date of notice from the trustee of
the defect and if the sponsor fails to correct or cure such defect within such
period and such defect materially and adversely affects the interests of the
certificateholders in the related mortgage loan, the sponsor will, in accordance
with the terms of the pooling and servicing agreement, within 90 days of the
date of notice, provide the trustee with a substitute mortgage loan (if within
two years of the closing date); provided that, if such defect would cause the
mortgage loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Internal Revenue Code, any such cure or substitution must
occur within 90 days from the date such breach was discovered.

THE CERTIFICATES

OFFERED CERTIFICATES. The offered certificates will have the characteristics
shown in the table above in this prospectus supplement. The offered certificates
will be sold by the depositor to the underwriter on the closing date.

CREDIT ENHANCEMENT

The credit enhancement provided for the benefit of the holders of the offered
certificates consists of the policy and overcollateralization, each as described
below and under "DESCRIPTION OF THE CERTIFICATES--CREDIT ENHANCEMENT" AND
"--OVERCOLLATERALIZATION PROVISIONS" in this prospectus supplement.

As of the closing date, the aggregate principal balance of the mortgage loans as
of the cut-off date will exceed the sum of the aggregate certificate principal
balances of the offered certificates and the Class P Certificates by an amount
equal to approximately $__________, which is equal to the initial certificate
principal balance of the Class CE Certificates. This amount represents
approximately ____% of the aggregate principal balance of the mortgage


                                      S-6


loans as of the cut-off date and is the initial amount of overcollateralization
required to be provided by the mortgage pool under the agreement. We cannot
assure you that sufficient interest will be generated by the mortgage loans to
maintain the required level of overcollateralization.

In addition, the insurer will deliver the policy to the trust administrator for
the benefit of the holders of the offered certificates. Under the policy, the
insurer will irrevocably and unconditionally guarantee payment to the trust
administrator on behalf of the trustee on each distribution date for the benefit
of the holders of the offered certificates, the full and complete payment of
insured payments with respect to the offered certificates calculated in
accordance with the original terms of the offered certificates when issued and
without regard to any amendment or modification of the offered certificates or
the agreement except amendments or modifications to which the insurer has given
its prior written consent. If any insured payment is avoided as a preference
payment under applicable bankruptcy, insolvency, receivership or similar law,
the insurer will pay this amount out of funds of the insurer.

[Additional information with respect to credit enhancement providers, required
pursuant to Item 1114(b) of Regulation AB, will be provided if applicable.]

 [Any third parties providing credit support for 10% or more of the pool assets
will be identified].

[PRE-FUNDING ACCOUNTS]

[Additional information with respect to the pre-funding accounts, required
pursuant to Item 1103(a)(5) of Regulation AB, will be provided if applicable.]

ADVANCES

The master servicer will make cash advances with respect to delinquent payments
of scheduled interest and principal on the mortgage loans for which it acts as
master servicer, in general, to the extent that the master servicer reasonably
believes that such cash advances can be repaid from future payments on the
related mortgage loans. If the master servicer fails to make any required
advances, the trustee may be obligated to do so, as described in this prospectus
supplement. These cash advances are only intended to maintain a regular flow of
scheduled interest and principal payments on the certificates and are not
intended to guarantee or insure against losses.

SERVICING FEE

With respect to each mortgage loan, the amount of the annual master servicing
fee that shall be paid to the master servicer is for a period of one full month,
equal to one-twelfth of the product of (a) [___]% and (b) the stated principal
balance of the mortgage loan for the calendar month preceding the month in which
the payment is due. Such fee shall be payable monthly, computed on the basis of
the same principal amount and period on which any related interest payment on a
mortgage loan is computed. The obligation to pay the master servicing fee is
limited to, and the master servicing fee is payable from the interest portion of
such monthly payments collected.

OPTIONAL TERMINATION

At its option, the majority holder of the Class CE Certificates (or if the
holder does not exercise the option, the master servicer or the insurer) may
purchase all of the mortgage loans, together with any properties in respect
thereof acquired on behalf of the trust, and thereby effect termination and
early retirement of the certificates, after the aggregate principal balance of
the mortgage loans (and properties acquired in respect thereof) remaining in the
trust has been reduced to less than __% or __% (as further provided in this
prospectus supplement) of the aggregate principal balance of the mortgage loans
as of _______ __, ____. SEE "POOLING AND SERVICING AGREEMENT-- TERMINATION" IN
THIS PROSPECTUS SUPPLEMENT AND "DESCRIPTION OF THE SECURITIES-- TERMINATION" IN
THE PROSPECTUS.

[A summary of other events that can trigger liquidation or amortization of the
asset pool or otherwise would alter the transaction structure or flow funds,
required pursuant to Item 1103(a)(3)(viii) of Regulation AB, will be provided if
applicable.]


FEDERAL INCOME TAX CONSEQUENCES

Three separate elections will be made to treat the trust fund as a REMIC for
federal income tax purposes. SEE "FEDERAL INCOME TAX
CONSEQUENCES--CHARACTERIZATION OF INVESTMENTS IN REMIC CERTIFICATES" IN THE
PROSPECTUS.

For further information regarding the federal income tax consequences of
investing in the offered certificates, SEE "FEDERAL INCOME TAX CONSEQUENCES" IN
THIS PROSPECTUS SUPPLEMENT AND IN THE PROSPECTUS.

RATINGS

It is a condition to the issuance of the certificates that the offered
certificates receive a rating of "Aaa" from _____________ and a rating of "AAA"
from _____________.

The ratings on the offered certificates are based in part on the ratings of the
claims-paying ability of the insurer by _______ and _________.

A security rating does not address the frequency of prepayments on the mortgage
loans or the corresponding effect on yield to investors. SEE "YIELD ON THE
CERTIFICATES" AND "RATINGS" IN THIS PROSPECTUS SUPPLEMENT AND "YIELD
CONSIDERATIONS" IN THE PROSPECTUS.

LEGAL INVESTMENT

The offered certificates will not constitute "mortgage related securities" for
purposes of SMMEA because the mortgage pool includes some mortgage loans that
are secured by subordinate liens on the related mortgaged properties. SEE "LEGAL
INVESTMENT" IN THIS PROSPECTUS SUPPLEMENT AND IN THE PROSPECTUS.

ERISA CONSIDERATIONS

The U.S. Department of Labor has issued an individual exemption, Prohibited
Transaction Exemption __-__, to the underwriter. This exemption generally
applies to certificates such as the offered certificates, and the servicing and
operation of asset pools such as the mortgage pool, provided that some
conditions are satisfied. SEE "ERISA CONSIDERATIONS" IN THIS PROSPECTUS
SUPPLEMENT AND IN THE PROSPECTUS.

                                  RISK FACTORS

         You should carefully consider, among other things, the following
factors in connection with the purchase of the offered certificates:

         [See version 1 of the prospectus supplement for some risk factors that
may be applicable.]

         [Appropriate risk factors from the following list are particular to the
securitization represented by this version of the prospectus supplement]

         [THE RATE AND TIMING OF PRINCIPAL DISTRIBUTIONS ON THE OFFERED
CERTIFICATES WILL BE AFFECTED BY PREPAYMENT SPEEDS AND BY THE PRIORITY OF
PAYMENT ON THE CERTIFICATES

         The rate and timing of distributions allocable to principal on the
offered certificates will depend, in general, on the rate and timing of
principal payments (including prepayments and collections upon defaults,
liquidations and repurchases) on the mortgage loans and the allocation thereof
to pay principal on the offered certificates as provided in this prospectus
supplement. As is the case with mortgage pass-through certificates generally,
the offered certificates are subject to substantial inherent cash-flow
uncertainties because the mortgage loans may be prepaid at any time. However,
with respect to approximately _____% of the mortgage loans, by aggregate
principal balance as of _______ __, ____, a prepayment may subject the related
mortgagor to a prepayment charge, which may act as a deterrent to prepayment of
the mortgage loan. SEE "THE MORTGAGE POOL" IN THIS PROSPECTUS SUPPLEMENT.

         Generally, when prevailing interest rates are increasing, prepayment
rates on mortgage loans tend to decrease; a decrease in the prepayment rates on
the mortgage loans will result in a reduced rate of return of principal to
investors in the offered certificates at a time when reinvestment at the higher
prevailing rates would be desirable. Conversely, when prevailing interest rates
are declining, prepayment rates on mortgage loans tend to increase; an increase
in the prepayment rates on the mortgage loans will result in a greater rate of
return of principal to investors in the offered certificates at a time when
reinvestment at comparable yields may not be possible.

         Except as otherwise described in this prospectus supplement,
distributions of principal will be made to the classes of offered certificates
according to the priorities described in this prospectus supplement, rather than
on a PRO RATA basis among these classes. The timing of commencement of principal
distributions and the weighted average life of each class of certificates will
be affected by the rates of prepayment on the mortgage loans experienced both
before and after the commencement of principal distributions on the class.

         During certain periods, no principal payments or a disproportionately
small portion of the amount of principal then payable to the offered
certificates will be distributed on the Class A-7 Certificates. During certain
other periods, a disproportionately large portion of the amount of principal
then payable to the offered certificates will be distributed on the Class A-7
Certificates as more fully described in this prospectus supplement.

         For further information regarding the effect of principal prepayments
on the weighted average lives of the offered certificates, SEE "YIELD ON THE
CERTIFICATES" IN THIS PROSPECTUS SUPPLEMENT, INCLUDING THE TABLE ENTITLED
"PERCENT OF INITIAL CERTIFICATE PRINCIPAL BALANCE OUTSTANDING AT THE FOLLOWING
PERCENTAGES OF THE PREPAYMENT ASSUMPTION"].


                                      S-11


         [THE YIELD TO MATURITY ON THE OFFERED CERTIFICATES WILL DEPEND ON A
VARIETY OF FACTORS

         The yield to maturity on the offered certificates will depend, in
general, on:

         o        the applicable purchase price; and

         o        the rate and timing of principal payments (including
                  prepayments and collections upon defaults, liquidations and
                  repurchases) on the mortgage loans, payments by the insurer,
                  and the allocation thereof to reduce the certificate principal
                  balance of the certificates, as well as other factors.

         The yield to investors on the offered certificates will be adversely
affected by any allocation thereto of interest shortfalls on the mortgage loans
not covered by the insurer.

         In general, if the offered certificates are purchased at a premium and
principal distributions on them occur at a rate faster than anticipated at the
time of purchase, the investor's actual yield to maturity will be lower than
that assumed at the time of purchase. Conversely, if the offered certificates
are purchased at a discount and principal distributions on them occur at a rate
slower than that anticipated at the time of purchase, the investor's actual
yield to maturity will be lower than that originally assumed.

         The proceeds to the depositor from the sale of the offered certificates
were determined based on a number of assumptions, including a prepayment
assumption of ___% of the prepayment vector (as more fully described in this
prospectus supplement) and weighted average lives corresponding thereto. No
representation is made that the mortgage loans will prepay at any particular
rate. The yield assumptions for the offered certificates will vary as determined
at the time of sale].

         [THE YIELD TO MATURITY ON THE OFFERED CERTIFICATES WILL BE SENSITIVE TO
THE RATE OF PREPAYMENTS ON THE MORTGAGE LOANS, ESPECIALLY THE CLASS A-7
CERTIFICATES

         The multiple class structure of the offered certificates causes the
yield of some classes to be particularly sensitive to changes in the rates of
prepayments of the mortgage loans. Because distributions of principal will be
made to the classes of offered certificates according to the priorities
described in this prospectus supplement, the yield to maturity on these classes
of certificates will be sensitive to the rates of prepayment on the mortgage
loans experienced both before and after the commencement of principal
distributions on the related class.

         In particular, the Class A-7 Certificates do not receive (unless the
certificate principal balances of the other classes of offered certificates have
been reduced to zero) any portion of principal payments prior to the
distribution date in _______ ____. In addition, the Class A-7 Certificates will
receive (unless the certificate principal balances of the other classes of
offered certificates have been reduced to zero) a disproportionately small or
large portion of the amount of principal then payable to the offered
certificates thereafter. Therefore, the weighted average life of the Class A-7
Certificates will be longer or shorter than would otherwise be the case. The
effect on the market value of the Class A-7 Certificates of changes in market
interest rates or market yields for similar securities may be greater or lesser
than for the other classes of offered certificates entitled to principal
distributions].

         [IF THE INSURER FAILS TO MEET ITS OBLIGATIONS UNDER THE POLICY, HOLDERS
OF THE OFFERED CERTIFICATES MAY EXPERIENCE A LOSS ON THEIR INVESTMENT

         If the protection created by the overcollateralization is insufficient
and the insurer is unable to meet its obligations under the policy, then you
could experience a loss of some of your investment. In


                                      S-12


addition, any reduction in a rating of the claims-paying ability of the insurer
may result in a reduction in the rating of the offered certificates].

FICO SCORES MENTIONED IN THIS PROSPECTUS SUPPLEMENT ARE NOT AN INDICATOR OF
FUTURE PERFORMANCE OF BORROWERS.

         Investors should be aware that FICO scores are based on past payment
history of the borrower. Investors should not rely on FICO scores as an
indicator of future borrower performance. See "The Mortgage Pools--FICO Scores"
in the base prospectus.

                                 USE OF PROCEEDS

         The Sponsor will sell the mortgage loans to the depositor and the
depositor will convey the mortgage loans to the trust fund in exchange for and
concurrently with the delivery of the Certificates (as defined in this
prospectus supplement). Net proceeds from the sale of the Certificates will be
applied by the depositor to the purchase of the mortgage loans from the Sponsor.
The net proceeds will represent the purchase price to be paid by the depositor
to the Sponsor for the mortgage loans. The mortgage loans were previously
purchased by the Sponsor either directly or indirectly from _____________ and
______________.


                                THE MORTGAGE POOL

GENERAL

         The pool of mortgage loans will consist of approximately _____
conventional, one- to four-family, fixed-rate mortgage loans secured by first
liens or second liens on residential real properties and having an aggregate
principal balance as of _______ __, ____ of approximately $___________, after
application of scheduled payments due on or before the Cut-off Date whether or
not received and subject to a permitted variance of plus or minus [5]%. The
mortgage loans have original terms to maturity of not greater than [30] years.

         References to percentages of the mortgage loans, unless otherwise
noted, are calculated based on the aggregate principal balance of the mortgage
loans as of the Cut-off Date.

         The mortgage loans are secured by first or second mortgages or deeds of
trust or other similar security instruments creating first liens or second liens
on residential properties consisting of attached, detached or semi-detached,
one- to four-family dwelling units, townhouses, individual condominium units,
individual units in planned unit developments and manufactured housing. The
mortgage loans to be included in the mortgage pool will be acquired by the
depositor from the Sponsor, who acquired the mortgage loans either directly or
indirectly from the Originators. _______________ will act as the master servicer
pursuant to the Agreement (as defined in this prospectus supplement) for the
mortgage loans and each of the Master Servicer and ________________ will act as
the servicer pursuant to the Agreement for the mortgage loans originated by it.
SEE "--UNDERWRITING STANDARDS; REPRESENTATIONS" IN THIS PROSPECTUS SUPPLEMENT.

         [As of the Cut-off date, not more than [ ]% of the mortgage loans were
more than 30 days delinquent in payments of principal and interest. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
one time during the twelve months preceding the cut-off date. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
two times


                                      S-13


during the twelve months preceding the Cut-off date. No more than approximately
[___]% of the mortgage loans have been more than 60 days delinquent one time
during the twelve months preceding the cut-off date. No more than approximately
[___]% of the mortgage loans have been more than 60 days delinquent two times
during the twelve months preceding the cut-off date.][No mortgage loan will be
more than 30 days delinquent as of the Cut-off Date.] A loan is considered to be
delinquent when a payment due on any due date remains unpaid as of the close of
business on the last business day immediately prior to the next monthly due
date. The determination as to whether a loan falls into this category is made as
of the close of business on the last business day of each month.

         __________ mortgage loans, representing approximately ____% of the
mortgage loans, have first payment dates occurring in _________ ____. With
respect to these mortgage loans, no principal amortization payments will be
distributed in _______ ____ unless principal payments on them are received in
the Prepayment Period applicable to the Distribution Date occurring in _______
____. On the Closing Date, however, cash will be deposited with the Trust
Administrator in an amount equal to interest accrued on these mortgage loans
(net of the related Servicing Fee (as defined in this prospectus supplement))
for the related Interest Accrual Period for distribution to the holders of the
offered certificates on the first Distribution Date.

         The mortgage loans have scheduled monthly payments due generally on the
first day of the month. Each mortgage loan will contain a customary
"due-on-sale" clause.

         Approximately _____% of the mortgage loans provide for payment by the
mortgagor of a prepayment charge in limited circumstances on certain prepayments
as provided in the related mortgage note. These mortgage loans provide for
payment of a Prepayment Charge on certain partial prepayments and all
prepayments in full made within a specified period not in excess of ____ years

_____% of the mortgage loans, by aggregate principal balance as of the Cut-off
Date, from ______________. All of the mortgage loans were originated or acquired
by the Originators generally in accordance with the underwriting criteria
described below.

REPRESENTATIONS AND WARRANTIES

         In the Mortgage Loan Purchase Agreement, pursuant to which the
Depositor purchased the mortgage loans from the Sponsor, the Sponsor made
certain representations and warranties to the Depositor concerning the mortgage
loans. The Indenture Trustee will be assigned all right, title and interest in
the Mortgage Loan Purchase Agreement insofar as they relate to such
representations and warranties made by the Sponsor.

         The representations and warranties of the Sponsor with respect to the
mortgage loans include the following, among others:

         (1) The information set forth in the mortgage loan schedule is true,
complete and correct in all material respects as of the Closing Date;

         (2) Immediately prior to the sale of the mortgage loans pursuant to the
Mortgage Loan Purchase Agreement, the Sponsor was the sole owner of beneficial
title and holder of each mortgage and mortgage note relating to the mortgage
loans and as of the Closing Date, or as of another specified date, is conveying
the same to the Depositor free and clear of any encumbrance, equity,
participation interest, lien, pledge, charge, mechanics' lien, assessment, claim
or security interest, and the Sponsor has full right and authority to sell and
assign each mortgage loan pursuant to the Mortgage Loan Purchase Agreement;

         (3) As of the Closing Date, the improvements on each Mortgaged Property
securing a Mortgage Loan are insured (by an insurer which is acceptable to the
Sponsor) against loss by fire, flood and such hazards as are covered under a
standard extended coverage endorsement in the locale in which the Mortgaged
Property is located, in an amount which is not less than the lesser of the
maximum insurable value of the improvements securing such Mortgage Loan or the
outstanding principal balance of the Mortgage Loan, but in no event in an amount
less than an amount that is required to prevent the Mortgagor from being deemed
to be a co-insurer thereunder;

         (4) Except to the extent insurance is in place which will cover such
damage, the physical property subject to any Mortgage is free of material damage
and is in good repair and there is no proceeding pending or threatened for the
total or partial condemnation of any Mortgaged Property;

         (5) The Mortgaged Property and all improvements thereon comply with all
requirements of any applicable zoning and subdivision laws and ordinances;

         (6) A lender's title insurance policy (on an ALTA or CLTA form) or
binder, or other assurance of title customary in the relevant jurisdiction
therefor in a form acceptable to Fannie Mae or Freddie Mac, was issued on the
date that each Mortgage Loan was created by a title insurance company which, to
the best of the Sponsor's knowledge, was qualified to do business in the
jurisdiction where the related Mortgaged Property is located, insuring the
Sponsor and its successors and assigns that the Mortgage is a first priority
lien on the related Mortgaged Property in the original principal amount of the
Mortgage Loan. The Sponsor is the sole insured under such lender's title
insurance policy, and such policy, binder or assurance is valid and remains in
full force and effect, and each such policy, binder or assurance shall contain
all applicable endorsements including a negative amortization endorsement, if
applicable;


                                      S-20


         (7) As of the Closing Date there is no material monetary default
existing under any Mortgage or the related Mortgage Note and there is no
material event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a default, breach or event of
acceleration; and neither the Sponsor nor any of its respective affiliates has
taken any action to waive any default, breach or event of acceleration; and no
foreclosure action is threatened or has been commenced with respect to the
Mortgage Loan;

         (8) Neither the Sponsor nor any prior holder of any Mortgage has
impaired, waived, altered or modified the Mortgage or Mortgage Notes in any
material respect (except that a Mortgage Loan may have been modified by a
written instrument which has been recorded, if necessary to protect the
interests of the owner of such Mortgage Loan or the Bonds, and which has been
delivered to the Indenture Trustee); satisfied, canceled or subordinated such
Mortgage in whole or in part; released the applicable Mortgaged Property in
whole or in part from the lien of such Mortgage; or executed any instrument of
release, cancellation or satisfaction with respect thereto; and

         (9) At the time of origination, if required, each Mortgaged Property
was the subject of an appraisal which conforms to the underwriting requirements
of the related originator; the Mortgage File contains an appraisal of the
applicable Mortgaged Property.

         In the case of a breach of any representation or warranty set forth
above which materially and adversely affects the value of the interests of
Bondholders or the Certificateholders, as applicable, or of the Depositor in any
of the mortgage loans, the Sponsor shall, within 90 days from the date of its
discovery or receipt of notice thereof, cure such breach or repurchase event in
all material respects or shall either (i) repurchase such Mortgage Loan from the
Issuing Entity at the repurchase price, or (ii) substitute one or more Eligible
Substitute Mortgage Loans for such Mortgage Loan, in each case in the manner and
subject to the conditions set forth in Mortgage Loan Purchase Agreement. The
obligations of the Sponsor to cure, repurchase or substitute shall constitute
the sole and exclusive remedy respecting a breach of such representations and
warranties available to the Depositor, the Issuing Entity, the
Certificateholders and the Bondholders against the sponsor.

ADDITIONAL INFORMATION

         The description in this prospectus supplement of the mortgage pool and
the mortgaged properties is based upon the mortgage pool as constituted as of
the close of business on the Cut-off Date, as adjusted for the scheduled
principal payments due on or before the Cut-off Date. Prior to the issuance of
the Certificates, mortgage loans may be removed from the mortgage pool as a
result of incomplete documentation or otherwise if the depositor deems the
removal necessary or desirable, and may be prepaid at any time. A limited number
of other mortgage loans may be included in the mortgage pool prior to the
issuance of the Certificates unless including these mortgage loans would
materially alter the characteristics of the mortgage pool as described in this
prospectus supplement. The depositor believes that the information set forth in
this prospectus supplement will be representative of the characteristics of the
mortgage pool as it will be constituted at the time the Certificates are issued,
although the range of mortgage rates and maturities and some other
characteristics of the mortgage loans may vary. In no event, however, will more
than 5% (by principal balance at the Cut-off Date) of the mortgage loans or
mortgage securities deviate from the characteristics of the mortgage loans or
mortgage securities set forth in the related prospectus supplement.

         If, as of the Closing Date, any material pool characteristic differs by
5% or more from the description in this prospectus supplement, revised
disclosure will be provided either in a supplement or in a current report on
Form 8-K.

                             STATIC POOL INFORMATION

         Static pool information material to this offering may be found at
__________________________. The Sponsor does not have any material static pool
information with respect to any mortgage loans of the same type as those
included in the trust fund originated by it prior to January 1, 2006, because
all or substantially all of these mortgage loans originated by the Sponsor prior
to that time were sold on a servicing released basis, and such information may
not be obtained without unreasonable effort or expense. With respect to any of
these mortgage loans originated by the Sponsor on or after January 1, 2006, the
static pool information provided does not include any information with respect
to any mortgage loan which was sold on a servicing released basis, except to the
extent the purchaser of that loan or another third-party has agreed to provide
that information back to the Sponsor and has actually provided it to the Sponsor
with indemnification.

         Information provided through the Internet address above will not be
deemed to be a part of this prospectus or the registration statement for the
securities offered hereby if it relates to any prior securities pool or vintage
formed before January 1, 2006, or with respect to the mortgage pool (if
applicable), any period before January 1, 2006.

                            YIELD ON THE CERTIFICATES

DELAY IN DISTRIBUTIONS ON THE OFFERED CERTIFICATES

         The effective yield to holders of the offered certificates of each
class will be less than the yields otherwise produced by their respective
Pass-Through Rates (as defined in this prospectus supplement) and purchase
prices because (1) on the first Distribution Date one month's interest is
payable on the offered certificates even though __ days will have elapsed from
the date on which interest begins to accrue on the offered certificates, (2) on
each succeeding Distribution Date the interest payable on the offered
certificates is the interest accrued during the month preceding the month of the
Distribution Date, which ends 24 days prior to the Distribution Date and (3)
during each Interest Accrual Period (as defined in this prospectus supplement)
(other than the first Interest Accrual Period), interest accrues on a
Certificate Principal Balance that may be less than the Certificate Principal
Balance of the class actually outstanding for the first 24 days of the Interest
Accrual Period.

POSSIBLE SHORTFALLS IN COLLECTIONS OF INTEREST

         When a principal prepayment in full is made on a mortgage loan, the
mortgagor is charged interest only for the period from the Due Date of the
preceding monthly payment up to the date of the prepayment, instead of for a
full month. When a partial principal prepayment is made on a mortgage loan, the
mortgagor is not charged interest on the amount of the prepayment for the month
in which the prepayment is made. In addition, the application of the Relief Act
to any mortgage loan will adversely affect, for an indeterminate period of time,
the ability of applicable Servicer to collect full amounts of interest on the
mortgage loan. SEE "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS--SOLDIERS' AND
SAILORS' CIVIL RELIEF ACT OF 1940" IN THE PROSPECTUS. Each Servicer is obligated
to pay from its own funds only those interest shortfalls attributable to full
and partial prepayments by the mortgagors on the related mortgage loans, but
only to the extent of its Servicing Fee for the related Due Period (as defined
in this prospectus supplement). SEE "POOLING AND SERVICING AGREEMENT--SERVICING
AND OTHER COMPENSATION AND PAYMENT OF EXPENSES" IN THIS PROSPECTUS SUPPLEMENT.
Accordingly, the effect of (1) any principal prepayments on the mortgage loans,
to the extent that any resulting shortfall exceeds any payments made by the
applicable Servicer from its own funds or (2) any shortfalls resulting from the
application of the Relief Act, will be to reduce the aggregate amount of
interest collected that is available for distribution to certificateholders. Any
of these shortfalls will be allocated among the Certificates as provided under


                                      S-22


"Description of the Certificates--Interest Distributions on the Offered
Certificates" and "--Overcollateralization Provisions" in this prospectus
supplement. The Policy will not cover any shortfalls resulting from application
of the Relief Act.

GENERAL PREPAYMENT CONSIDERATIONS

         The rate of principal payments on the offered certificates, the
aggregate amount of distributions on the offered certificates and the yield to
maturity of the offered certificates will be related to the rate and timing of
payments of principal on the mortgage loans. Furthermore, since mortgage loans
secured by second liens are not generally viewed by borrowers as permanent
financing and generally carry a high rate of interest, the mortgage loans may
experience a higher rate of prepayments than traditional mortgage loans. The
rate of principal payments on the mortgage loans will in turn be affected by the
amortization schedules of the mortgage loans and the rate of principal
prepayments on the mortgage loans (including for this purpose, payments
resulting from refinancings, liquidations of the mortgage loans due to defaults,
casualties, condemnations and repurchases, whether optional or required, by the
depositor, the Originators, the Sponsor, the majority holder of the Class CE
Certificates, the insurer or the master servicer, as the case may be). The
mortgage loans generally may be prepaid by the mortgagors at any time; however,
as described under "The Mortgage Pool" in this prospectus supplement, with
respect to approximately _____% of the mortgage loans, by aggregate principal
balance as of the Cut-off Date, a prepayment may subject the related mortgagor
to a Prepayment Charge.

         Prepayments, liquidations and repurchases of the mortgage loans will
result in distributions in respect of principal to the holders of the offered
certificates that otherwise would be distributed over the remaining terms of the
mortgage loans. SEE "MATURITY AND PREPAYMENT CONSIDERATIONS" IN THE PROSPECTUS.
Since the rates of payment of principal on the mortgage loans will depend on
future events and a variety of factors (as described more fully in this
prospectus supplement and in the prospectus under "Yield Considerations" and
"Maturity and Prepayment Considerations"), no assurance can be given as to this
rate or the rate of principal prepayments. The extent to which the yield to
maturity of the offered certificates may vary from the anticipated yield will
depend upon the degree to which the offered certificates are purchased at a
discount or premium and the degree to which the timing of payments on the
offered certificates is sensitive to prepayments on the mortgage loans. Further,
an investor should consider, in the case of any Offered Certificate purchased at
a discount, the risk that a slower than anticipated rate of principal payments
on the mortgage loans could result in an actual yield to the investor that is
lower than the anticipated yield and, in the case of any Offered Certificate
purchased at a premium, the risk that a faster than anticipated rate of
principal payments could result in an actual yield to the investor that is lower
than the anticipated yield. In general, the earlier a prepayment of principal is
made on the mortgage loans, the greater the effect on the yield to maturity of
the offered certificates. As a result, the effect on an investor's yield of
principal payments occurring at a rate higher (or lower) than the rate
anticipated by the investor during the period immediately following the issuance
of the offered certificates would not be fully offset by a subsequent like
reduction (or increase) in the rate of principal payments.

         It is highly unlikely that the mortgage loans will prepay at any
constant rate until maturity or that all of the mortgage loans will prepay at
the same rate. Moreover, the timing of prepayments on the mortgage loans may
significantly affect the actual yield to maturity on the offered certificates,
even if the average rate of principal payments experienced over time is
consistent with an investor's expectation.

         The rate of payments (including prepayments) on pools of mortgage loans
is influenced by a variety of economic, geographic, social and other factors. If
prevailing mortgage rates fall significantly below the mortgage rates on the
mortgage loans, the rate of prepayment (and refinancing) would be expected to
increase. Conversely, if prevailing mortgage rates rise significantly above the
mortgage rates


                                      S-23


on the mortgage loans, the rate of prepayment on the mortgage loans would be
expected to decrease. Other factors affecting prepayment of mortgage loans
include changes in mortgagors' housing needs, job transfers, unemployment,
mortgagors' net equity in the mortgaged properties and servicing decisions.
There can be no certainty as to the rate of prepayments on the mortgage loans
during any period or over the life of the Certificates. SEE "YIELD
CONSIDERATIONS" AND "MATURITY AND PREPAYMENT CONSIDERATIONS" IN THE PROSPECTUS.

         Because principal distributions are paid to some classes of offered
certificates before other classes, holders of classes of offered certificates
having a later priority of payment bear a greater risk of losses (because these
Certificates will represent an increasing percentage interest in the trust fund
prior to the commencement of their receipt of distributions of principal) than
holders of classes having earlier priorities for distribution of principal. In
particular, with respect to the Lockout Certificates (as defined in this
prospectus supplement), as described under "Description of the
Certificates--Principal Distributions on the Offered Certificates" in this
prospectus supplement, during some periods, no principal payments or a
disproportionately small portion of the amount of principal then payable to the
offered certificates will be distributed on the Lockout Certificates, and during
other periods, a disproportionately large portion of the amount of principal
then payable to the offered certificates will be distributed on the Lockout
Certificates. Unless the Certificate Principal Balances of the offered
certificates (other than the Lockout Certificates) have been reduced to zero,
the Lockout Certificates will not be entitled to receive any distributions of
principal payments prior to the Distribution Date in _______ ____.

         In general, defaults on mortgage loans are expected to occur with
greater frequency in their early years and the rate of defaults and the severity
of losses on mortgage loans secured by second liens may be substantially higher
than mortgage loans secured by first liens. In addition, default rates may be
higher for mortgage loans used to refinance an existing mortgage loan. In the
event of a mortgagor's default on a mortgage loan, other than as provided by the
Policy as described in this prospectus supplement, there can be no assurance
that recourse will be available beyond the specific mortgaged property pledged
as security for repayment. SEE "THE MORTGAGE POOL--UNDERWRITING STANDARDS;
REPRESENTATIONS" IN THIS PROSPECTUS SUPPLEMENT.

MARKET INTEREST RATE CONSIDERATIONS

         Because the mortgage rates on the mortgage loans and the Pass-Through
Rates on the offered certificates are fixed, these rates will not change in
response to changes in market interest rates. Accordingly, if mortgage market
interest rates or market yield for securities similar to these offered
certificates were to rise, the market value of these offered certificates may
decline.

BALLOON PAYMENTS

         The mortgage loans with Balloon Payments will not be fully-amortizing
over their terms to maturity, and will require substantial principal payments at
their stated maturity. Mortgage loans of this type involve a greater degree of
risk than self-amortizing loans because the ability of a borrower to make a
Balloon Payment typically will depend upon the borrower's ability either to
fully refinance the loan or to sell the related mortgaged property at a price
sufficient to permit the borrower to make the Balloon Payment. The ability of a
borrower to accomplish either of these goals will be affected by a number of
factors, including the value of the related mortgaged property, the level of
available mortgage rates at the time of sale or refinancing, the borrower's
equity in the related mortgaged property, tax laws, prevailing general economic
conditions and the availability of credit for loans secured by residential
property. Because the ability of a borrower to make a Balloon Payment typically
will depend upon the borrower's ability to either refinance the loan or to sell
the related mortgaged property, there is a risk that the Balloon Loans may
default at maturity. Any defaulted Balloon Payment that extends the maturity of
a mortgage


                                      S-24


loan may delay distributions of principal on the offered certificates and
thereby extend the weighted average life of the Certificates and, if the
Certificates were purchased at a discount, reduce the yield on the Certificates.

WEIGHTED AVERAGE LIVES

         Weighted average life refers to the amount of time that will elapse
from the date of issuance of a security until each dollar of principal of the
security will be repaid to the investor. The weighted average life of each class
of offered certificates will be influenced by the rate at which principal on the
mortgage loans is paid, which may be in the form of scheduled payments or
prepayments (including repurchases and prepayments of principal by the borrower
as well as amounts received by virtue of condemnation, insurance or foreclosure
with respect to the mortgage loans), and the timing thereof.

         Except as otherwise described under "Description of the
Certificates--Principal Distributions on the Offered Certificates" in this
prospectus supplement, distributions of principal will be made to the classes of
the offered certificates according to the priorities described in this
prospectus supplement, rather than on a pro rata basis among these classes,
unless an insurer default exists. The timing of commencement of principal
distributions to each class of the offered certificates and the weighted average
life of each class will be affected by the rates of prepayment on the mortgage
loans experienced both before and after the commencement of principal
distributions on each class. Moreover, because the Lockout Certificates do not
receive (unless the Certificate Principal Balances of the offered certificates,
other than the Lockout Certificates, have been reduced to zero) any portion of
principal payments prior to the Distribution Date occurring in _______ ____ and
thereafter will receive (unless the Certificate Principal Balances of the
offered certificates, other than the Lockout Certificates, have been reduced to
zero) a disproportionately small or large portion of principal payments, the
weighted average life of the Lockout Certificates will be longer or shorter than
would otherwise be the case, and the effect on the market value of the Lockout
Certificates of changes in market interest rates or market yields for similar
securities may be greater or lesser than for the other classes of offered
certificates entitled to principal distributions.

         Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. The model used in this prospectus supplement
assumes a prepayment rate for the mortgage loans of ___% of the Prepayment
Vector. A ___% Prepayment Vector assumes that the outstanding balance of a pool
of mortgage loans prepays at a rate of ____% CPR in the first month of the life
of the pool, this rate increasing by an additional approximate ____% CPR
(precisely __/__, expressed as a percentage) each month thereafter through the
eleventh month of the life of the pool, and the rate thereafter remaining
constant at __% CPR for the remainder of the life of the pool. A __% Prepayment
Vector assumes, for example, that the outstanding balance of a pool of mortgage
loans prepays at a rate of ____% CPR in the first month of the life of the pool,
the rate increasing by an additional approximate ____% CPR (precisely __/__,
expressed as a percentage) each month thereafter through the eleventh month of
the life of the pool, and the rate thereafter remaining constant at _____% CPR
for the remainder of the life of the pool. No representation is made that the
mortgage loans in the mortgage pool will prepay at the above-described rates or
any other rate. CPR refers to the Constant Prepayment Rate model, which assumes
that the outstanding principal balance of a pool of mortgage loans prepays at a
specified constant annual rate or CPR. In generating monthly cash flows, this
rate is converted to an equivalent constant monthly rate. To assume __% CPR or
any other CPR percentage is to assume that the stated percentage of the
outstanding principal balance of the pool is prepaid over the course of a year.

         The tables following the next paragraph indicate the percentage of the
initial Certificate Principal Balance of the offered certificates that would be
outstanding after each of the dates shown at various percentages of the
Prepayment Assumption and the corresponding weighted average lives of the


                                      S-25


Certificates. The tables are based on the following assumptions (the
"Structuring Assumptions"): (1) the mortgage pool consists of ______ mortgage
loans with the characteristics set forth below, (2) distributions on the
Certificates are received, in cash, on the 25th day of each month, commencing in
_______ ____, (3) the mortgage loans prepay at the percentages of the Prepayment
Assumption indicated, (4) no defaults or delinquencies occur in the payment by
mortgagors of principal and interest on the mortgage loans and no shortfalls due
to the application of the Relief Act are incurred, (5) none of the depositor,
the Originators, the Sponsor, the majority holder of the Class CE Certificates,
the Insurer, the Servicers, the Master Servicer or any other person purchases
from the trust fund any mortgage loan pursuant to any obligation or option under
the Agreement, except as indicated in footnote two in the tables below, (6)
scheduled monthly payments on the mortgage loans are received on the first day
of each month commencing in _______ ____, and are computed prior to giving
effect to any prepayments received in the prior month, (7) prepayments
representing payment in full of individual mortgage loans are received on the
last day of each month commencing in _______ ____, and include 30 days' interest
on the mortgage loans, (8) the scheduled monthly payment for each mortgage loan
is calculated based on its principal balance, mortgage rate, original term to
stated maturity and remaining term to stated maturity such that the mortgage
loan will amortize in amounts sufficient to repay the remaining principal
balance of the mortgage loan by its remaining term to stated maturity, (9) the
Certificates are purchased on _______ __, ____, (10) the Servicing Fee Rate is
equal to ____% per annum, the Master Servicing Fee Rate is equal to ____% per
annum on the mortgage loans directly serviced by ________ and is equal to ____%
per annum on the mortgage loans serviced by __________, the Administration Fee
Rate is equal to ______% per annum and the amount of the premium payable to the
insurer is as described under the heading "Pooling and Servicing Agreement--Some
Matters Regarding the Insurer", (11) the first _____ mortgage loans in the table
below are mortgage loans that do not by their terms have Prepayment Charges and
the last _____ mortgage loans in the table below are mortgage loans that by
their terms do have Prepayment Charges, (12) the _____ mortgage loan in the

_____, ______, _____ and _____ mortgage loans in the table below are mortgage
loans that have been originated by __________ and the _____, _____, _____,
_____, _____ and ______ mortgage loans in the table below are mortgage loans
that have been originated by _________.

         There will be discrepancies between the characteristics of the actual
mortgage loans and the characteristics assumed in preparing the tables. Any of
these discrepancies may have an effect upon the percentages of the initial
Certificate Principal Balance outstanding (and the weighted average lives) of
the offered certificates set forth in the tables. In addition, since the actual
mortgage loans included in the mortgage pool will have characteristics that
differ from those assumed in preparing the tables set forth below, the offered
certificates may mature earlier or later than indicated by the tables. Based on
the foregoing Structuring Assumptions, the tables indicate the weighted average
lives of the offered certificates and sets forth the percentages of the initial
Certificate Principal Balance of the offered certificates that would be
outstanding after each of the Distribution Dates shown, at various percentages
of the Prepayment Assumption. Neither the prepayment model used in this
prospectus supplement nor any other prepayment model or assumption purports to
be an historical description of prepayment experience or a prediction of the
anticipated rate of prepayment of any pool of mortgage loans, including the
mortgage loans included in the mortgage pool. Variations in the prepayment
experience and the balance of the mortgage loans that prepay may increase or
decrease the percentages of initial Certificate Principal Balances (and weighted
average lives) shown in the following table. These variations may occur even if
the average prepayment experience of all the mortgage loans equals any of the
specified percentages of the Prepayment Assumption.

         There is no assurance that prepayments of the mortgage loans will
conform to any of the levels of the Prepayment Assumption indicated in the
tables above, or to any other level, or that the actual weighted average lives
of the offered certificates will conform to any of the weighted average lives
set forth in the tables above. Furthermore, the information contained in the
tables with respect to the weighted average lives of the offered certificates is
not necessarily indicative of the weighted average lives that might be
calculated or projected under different or varying prepayment assumptions.

         The characteristics of the mortgage loans will differ from those
assumed in preparing the tables above. In addition, it is unlikely that any
mortgage loan will prepay at any constant percentage until maturity, that all of
the mortgage loans will prepay at the same rate. The timing of changes in the
rate of prepayments may significantly affect the actual yield to maturity to
investors, even if the average rate of principal prepayments is consistent with
the expectations of investors.

                         DESCRIPTION OF THE CERTIFICATES

GENERAL

         The Impac Secured Assets Corp., Mortgage Pass-Through Certificates,
Series ____-___ will consist of ______ classes of certificates, designated as:
(1) the Class A-1 Certificates, the Class A-2 Certificates, the Class A-3
Certificates, the Class A-4 Certificates, the Class A-5 Certificates, the Class
A-6 Certificates ; (2) the Class A-7 Certificates; (3) the Class CE
Certificates; (4) the Class P Certificates and (5) the Class R-I Certificates,
the Class R-II Certificates and the Class R-III Certificates. Only the offered
certificates are offered by this prospectus supplement. The Class CE
Certificates, the Class P Certificates and the Residual Certificates, which are
not being offered by this prospectus supplement, will be sold by the depositor
to ______________ on the Closing Date.


                                      S-28


         Distributions on the offered certificates will be made on the 25th day
of each month, or, if the day is not a business day, on the next succeeding
business day, beginning in _______ ____.

         The Certificates represent in the aggregate the entire beneficial
ownership interest in a trust fund consisting primarily of the mortgage pool of
conventional, one- to four-family, fixed-rate, first lien and second lien
mortgage loans having original terms to maturity of not greater than [30] years.
The Certificates have an aggregate principal balance as of the Cut-off Date of
approximately $___________, subject to a permitted variance as described under
"The Mortgage Pool" in this prospectus supplement.

         Each class of offered certificates will have the approximate initial
Certificate Principal Balance and Pass- Through Rate as set forth under "Summary
of Prospectus Supplement--Offered Certificates" above. The Pass-Through Rate on
the Class A-6 Certificates for any Distribution Date will be a rate per annum
equal to the lesser of (1) _____% and (2) the Net WAC Pass-Through Rate for the
related Distribution Date. The offered certificates in the aggregate evidence an
initial undivided interest of approximately _____% in the trust fund and the
Class CE Certificates evidence an initial undivided interest of approximately
____% in the trust fund.

         The offered certificates will be issued, maintained and transferred on
the book-entry records of the DTC and its participants (as defined in this
prospectus supplement) in minimum denominations of $[10,000] and integral
multiples of $[1.00] in excess thereof.

         The offered certificates will initially be represented by one or more
global certificates registered in the name of the nominee of the DTC (or any
successor clearing agency selected by the depositor), except as provided below.
The depositor has been informed by the DTC that the DTC's nominee will be Cede &
Co.. No person acquiring an interest in any Offered Certificate will be entitled
to receive a certificate representing the person's interest, except as set forth
below under "--Definitive Certificates". Unless and until a certificate is
issued in fully registered certificated form under the limited circumstances
described in this prospectus supplement, all references to actions by
certificateholders with respect to the offered certificates shall refer to
actions taken by the DTC upon instructions from its participants, and all
references in this prospectus supplement to distributions, notices, reports and
statements to certificateholders with respect to the offered certificates shall
refer to distributions, notices, reports and statements to the DTC or CEDE, as
the registered holder of the offered certificates, for distribution to
Certificate Owners in accordance with the DTC procedures. SEE "--REGISTRATION OF
THE OFFERED CERTIFICATES" AND "--DEFINITIVE CERTIFICATES" IN THIS PROSPECTUS
SUPPLEMENT.

         Any Definitive Certificates will be transferable and exchangeable at
the offices of the Trust Administrator. No service charge will be imposed for
any registration of transfer or exchange, but the Trust Administrator may
require payment of a sum sufficient to cover any tax or other governmental
charge imposed in connection therewith.

         All distributions to holders of the Certificates, other than the final
distribution on any class of Certificates, will be made by the Trust
Administrator on behalf of the Trustee to the persons in whose names the
Certificates are registered at the close of business on each Record Date. These
distributions will be made either (a) by check mailed to the address of each
certificateholder as it appears in the Certificate Register or (b) upon written
request to the Trust Administrator at least five business days prior to the
relevant Record Date by any holder of Certificates having an aggregate initial
Certificate Principal Balance that is in excess of the lesser of (1) $5,000,000
or (2) two-thirds of the initial aggregate Certificate Principal Balance of the
class of Certificates, by wire transfer in immediately available funds to the
account of the certificateholder specified in the request. The final
distribution on any class of Certificates will be made in like manner, but only
upon presentment and surrender of the Certificates at


                                      S-29


the corporate trust office of the Trust Administrator or the other location
specified in the notice to certificateholders of the final distribution.

REGISTRATION OF THE OFFERED CERTIFICATES

         The DTC is a limited-purpose trust company organized under the laws of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. the DTC was created to hold
securities for its participating organizations and to facilitate the clearance
and settlement of securities transactions between participants through
electronic book entries, thereby eliminating the need for physical movement of
certificates. participants include securities brokers and dealers (including
[Name of Underwriter]), banks, trust companies and clearing corporations.
Indirect access to the DTC system is also available to others such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

         Certificate Owners that are not participants or indirect participants
but desire to purchase, sell or otherwise transfer ownership of, or other
interests in, the offered certificates may do so only through participants and
indirect participants. In addition, Certificate Owners will receive all
distributions of principal of and interest on the offered certificates from the
Trust Administrator through the DTC and the DTC participants. The Trust
Administrator will forward payments to the DTC in same day funds and the DTC
will forward the payments to participants in next day funds settled through the
New York Clearing House. Each participant will be responsible for disbursing the
payments to indirect participants or to Certificate Owners. Unless and until
Definitive Certificates are issued, it is anticipated that the only
certificateholder of the offered certificates will be CEDE, as nominee of the
DTC. Certificate Owners will not be recognized by the Trust Administrator as
certificateholders, as the term is used in the Agreement, and Certificate Owners
will be permitted to exercise the rights of certificateholders only indirectly
through the DTC and its participants.

         Under the rules, regulations and procedures creating and affecting the
DTC and its operations, the DTC is required to make book-entry transfers of
offered certificates among participants and to receive and transmit
distributions of principal of, and interest on, the offered certificates.
Participants and indirect participants with which Certificate Owners have
accounts with respect to the offered certificates similarly are required to make
book-entry transfers and receive and transmit the payments on behalf of their
respective Certificate Owners. Accordingly, although Certificate Owners will not
possess Definitive Certificates, the Rules provide a mechanism by which
Certificate Owners through their participants and indirect participants will
receive payments and will be able to transfer their interest.

         Because the DTC can only act on behalf of participants, who in turn act
on behalf of indirect participants and on behalf of certain banks, the ability
of a Certificate Owner to pledge offered certificates to persons or entities
that do not participate in the DTC system, or to otherwise act with respect to
the Certificates, may be limited due to the absence of physical certificates for
the offered certificates. In addition, under a book- entry format, Certificate
Owners may experience delays in their receipt of payments since distribution
will be made by the Trust Administrator to CEDE, as nominee for the DTC.

         Under the Rules, the DTC will take action permitted to be taken by a
certificateholder under the Agreement only at the direction of one or more
participants to whose the DTC account the offered certificates are credited.
Additionally, under the Rules, the DTC will take the actions with respect to
specified Voting Rights only at the direction of and on behalf of participants
whose holdings of offered certificates evidence the specified Voting Rights. the
DTC may take conflicting actions with respect to


                                      S-30


Voting Rights to the extent that participants whose holdings of offered
certificates evidence these Voting Rights, authorize divergent action.

         The depositor, the Servicers, the Trustee, the Trust Administrator, the
Originators, the insurer and the Sponsor will have no liability for any actions
taken by the DTC or its nominee, including actions for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the
offered certificates held by CEDE, as nominee for the DTC, or for maintaining,
supervising or reviewing any records relating to these beneficial ownership
interests.

DEFINITIVE CERTIFICATES

         Definitive Certificates will be issued to Certificate Owners or their
nominees, rather than to the DTC or its nominee, only if (1) the depositor
advises the Trust Administrator in writing that the DTC is no longer willing or
able to discharge properly its responsibilities as Clearing Agency with respect
to the offered certificates and the depositor is unable to locate a qualified
successor, (2) the depositor, at its option, advises the Trust Administrator in
writing that it elects to terminate the book-entry system through the DTC, or
(3) after the occurrence of an Event of Default, Certificate Owners representing
in the aggregate not less than 51% of the Voting Rights of the offered
certificates advise the Trust Administrator and the DTC through participants, in
writing, that the continuation of a book-entry system through the DTC (or a
successor thereto) is no longer in the Certificate Owners' best interest.

         Upon the occurrence of any event described in the immediately preceding
paragraph, the Trust Administrator is required to notify all Certificate Owners
through participants of the availability of Definitive Certificates. Upon
surrender by the DTC of the Definitive Certificates representing the offered
certificates and receipt of instructions for re-registration, the Trust
Administrator will reissue the offered certificates as Definitive Certificates
issued in the respective principal amounts owned by individual Certificate
Owners, and thereafter the Trust Administrator will recognize the holders of the
Definitive Certificates as certificateholders under the Agreement. These
Definitive Certificates will be issued in minimum denominations of $10,000,
except that any beneficial ownership represented by a Offered Certificate in an
amount less than $10,000 immediately prior to the issuance of a Definitive
Certificate shall be issued in a minimum denomination equal to the amount
represented by the Offered Certificate.

INTEREST DISTRIBUTIONS ON THE OFFERED CERTIFICATES

         Distributions in respect of interest will be made on each Distribution
Date to the holders of each class of offered certificates in an amount
(allocable among these Certificates PRO RATA in accordance with the respective
amounts payable as to each in respect of interest) equal to the Interest
Distribution Amount for the class for the Distribution Date.

         All distributions of interest on the offered certificates will be based
on a 360-day year consisting of twelve 30-day months. Except as otherwise
described in this prospectus supplement, on any Distribution Date, distributions
of the Interest Distribution Amount for a class of Certificates will be made in
respect of the class of Certificates, to the extent provided in this prospectus
supplement, on a PARI PASSU basis, based on the Certificate Principal Balance of
the Certificates of each class.

         Subject to the terms of the Policy, any interest losses incurred by the
offered certificates (other than shortfalls resulting from the application of
the Relief Act) will be covered under the Policy. Notwithstanding the foregoing,
however, if payments are not made as required under the Policy, any of these
interest losses may be borne by the offered certificates to the extent the
amount of the losses is not paid from Net Monthly Excess Cashflow (as defined in
this prospectus supplement), in the priority described under
"--Overcollateralization Provisions" in this prospectus supplement.


                                      S-31


         The Certificate Principal Balance of an Offered Certificate outstanding
at any time represents the then maximum amount that the holder thereof is
entitled to receive as distributions allocable to principal from the cash flow
on the mortgage loans and the other assets in the trust fund. The Certificate
Principal Balance of any class of offered certificates as of any date of
determination is equal to the initial Certificate Principal Balance thereof
reduced by the aggregate of (1) all amounts allocable to principal previously
distributed with respect to the Certificate and (2) any reductions in the
Certificate Principal Balance thereof deemed to have occurred in connection with
allocations of Realized Losses in the manner described in this prospectus
supplement. The Certificate Principal Balance of the Class CE Certificates as of
any date of determination is equal to the excess, if any, of (1) the then
aggregate principal balance of the mortgage loans over (2) the then aggregate
Certificate Principal Balance of the offered certificates and the Class P
Certificates.

PRINCIPAL DISTRIBUTIONS ON THE OFFERED CERTIFICATES

         On each Distribution Date, the Principal Distribution Amount will be
distributed to the holders of the offered certificates then entitled to the
distributions.

         Notwithstanding the foregoing, as described under
"--Overcollateralization Provisions" in this prospectus supplement, no amounts
will be distributed to the holders of the offered certificates pursuant to
clause (5) above except to the extent of any Net Monthly Excess Cashflow
remaining after payment to the holders of the offered certificates of all
amounts in respect of Realized Losses pursuant to clause (4) above and payment
to the insurer of any Cumulative Insurance Payments.

         In no event will the Principal Distribution Amount with respect to any
Distribution Date be (x) less than zero or (y) greater than the then outstanding
aggregate Certificate Principal Balance of the offered certificates.

         In addition, on each Distribution Date, funds received as a result of a
claim under the Policy in respect of the principal portion of Realized Losses
allocated to the offered certificates will be distributed by the Trust
Administrator on behalf of the Trustee to the holders of the Certificates. SEE
"--FINANCIAL GUARANTY INSURANCE POLICY" IN THIS PROSPECTUS SUPPLEMENT.

         Distributions of the Principal Distribution Amount (and any amounts
distributable in accordance with clauses first and third under
"--Overcollateralization Provisions" in this prospectus supplement) on the
offered certificates on each Distribution Date will be made as follows:

         FIRST, to the holders of the Lockout Certificates, the Lockout
         Distribution Percentage of the Principal Distribution Amount, until the
         Certificate Principal Balance thereof has been reduced to zero;

         SECOND, to the holders of the Class A-1 Certificates, until the
         Certificate Principal Balance thereof has been reduced to zero; THIRD,
         to the holders of the Class A-2 Certificates, until the Certificate
         Principal Balance thereof has been reduced to zero;

         FOURTH, to the holders of the Class A-3 Certificates, until the
         Certificate Principal Balance thereof has been reduced to zero;

         FIFTH, to the holders of the Class A-4 Certificates, until the
         Certificate Principal Balance thereof has been reduced to zero;


                                      S-32


         SIXTH, to the holders of the Class A-5 Certificates, until the
         Certificate Principal Balance thereof has been reduced to zero;

         SEVENTH, to the holders of the Class A-6 Certificates, until the
         Certificate Principal Balance thereof has been reduced to zero; and

         EIGHTH, to the holders of the Lockout Certificates, until the
Certificate Principal Balance thereof has been reduced to zero.

         Notwithstanding the foregoing priorities, if an Insurer Default exists,
the priority of distributions of principal among the offered certificates will
be disregarded and distributions allocable to principal will be paid on each
succeeding Distribution Date to holders of the offered certificates, on a PRO
RATA basis, based on the Certificate Principal Balances thereof.

CREDIT ENHANCEMENT

         The credit enhancement provided for the benefit of the holders of the
offered certificates consists of the policy and overcollateralization, each as
described under "--OVERCOLLATERALIZATION PROVISIONS" and "--FINANCIAL GUARANTY
INSURANCE POLICY" below.

         [Additional information with respect to credit enhancement providers,
required pursuant to Item 1114(b) of Regulation AB, will be provided if
applicable.]

OVERCOLLATERALIZATION PROVISIONS

         The weighted average mortgage rate (net of the Administration Fee Rate,
the Servicing Fee Rate, the Master Servicing Fee Rate and the amount of the
premium payable to the insurer) for the mortgage loans is generally expected to
be higher than the weighted average of the Pass-Through Rate on the offered
certificates, thus generating excess interest collections which, in the absence
of Realized Losses, will not be necessary to fund interest distributions on the
offered certificates. The Agreement requires that, on each Distribution Date,
the Net Monthly Excess Cashflow, if any, be applied on the Distribution Date as
an accelerated payment of principal on the offered certificates, but only to the
limited extent hereafter described.

         With respect to any Distribution Date, any Net Monthly Excess Cashflow
(or, in the case of clause first below, the Net Monthly Excess Cashflow
exclusive of any Overcollateralization Reduction Amount) shall be paid as
follows:

         FIRST, to the holders of the class or classes of offered certificates
         then entitled to receive distributions in respect of principal, in an
         amount equal to the principal portion of any Realized Losses incurred
         or deemed to have been incurred on the mortgage loans;

         SECOND, to the insurer, in an amount equal to any Cumulative Insurance
         Payments;

         THIRD, to the holders of the class or classes of offered certificates
         then entitled to receive distributions in respect of principal, in an
         amount equal to the Overcollateralization Increase Amount;

         FOURTH, to the holders of the offered certificates, in an amount equal
         to the Certificates' allocated share of any shortfalls resulting from
         the application of the Relief Act with respect to the mortgage loans;


                                      S-33


         FIFTH, to the insurer, for any amounts remaining due to the insurer
         under the terms of the Insurance Agreement (as defined in this
         prospectus supplement);

         SIXTH, to the holders of the Class CE Certificates as provided in the
         Agreement; and

         SEVENTH, to the holders of the Residual Certificates, any remaining
         amounts; provided that if the Distribution Date is the Distribution
         Date immediately following the expiration of the latest Prepayment
         Charge term or any Distribution Date thereafter, then any of these
         remaining amounts will be distributed FIRST, to the holders of the
         Class P Certificates, until the Certificate Principal Balance thereof
         has been reduced to zero; and SECOND, to the holders of the Residual
         Certificates.

         As of the Closing Date, the aggregate principal balance of the mortgage
loans as of the Cut-off Date will exceed the sum of the aggregate Certificate
Principal Balances of the offered certificates and the Class P Certificates by
an amount equal to approximately $__________, which is equal to the initial
Certificate Principal Balance of the Class CE Certificates. This amount
represents approximately ____% of the aggregate principal balance of the
mortgage loans as of the Cut-off Date and is the initial amount of
overcollateralization required to be provided by the mortgage pool under the
Agreement. Under the Agreement, the Overcollateralized Amount is required to be
maintained at the Required Overcollateralization Amount. In the event that
Realized Losses are incurred on the mortgage loans, these Realized Losses may
result in an overcollateralization deficiency since these Realized Losses will
reduce the principal balance of the mortgage loans without a corresponding
reduction to the aggregate Certificate Principal Balances of the offered
certificates. In this event, the Agreement requires the payment from Net Monthly
Excess Cashflow, subject to available funds, of an amount equal to the
overcollateralization deficiency, which shall constitute a principal
distribution on the offered certificates in reduction of the Certificate
Principal Balances thereof. This has the effect of accelerating the amortization
of the offered certificates relative to the amortization of the mortgage loans,
and of increasing the Overcollateralized Amount.

         In the event that the Required Overcollateralized Amount is required to
step up on any Distribution Date, the Agreement provides that all Net Monthly
Excess Cashflow remaining after the distributions described in clauses first and
second above will be distributed in respect of the Overcollateralization
Increase Amount for the offered certificates until the Overcollateralized Amount
is equal to the stepped up Required Overcollateralized Amount. This has the
effect of accelerating the amortization of the offered certificates relative to
the amortization of the mortgage loans, and of increasing the Overcollateralized
Amount.

         In the event that the Required Overcollateralized Amount is permitted
to step down on any Distribution Date, the Agreement provides that a portion of
the principal which would otherwise be distributed to the holders of the offered
certificates on the related Distribution Date shall be distributed to the
holders of the Class CE Certificates on the related Distribution Date. With
respect to each related Distribution Date, the Principal Distribution Amount
will be reduced by the amount by which the Overcollateralized Amount exceeds the
Required Overcollateralized Amount after taking into account all other
distributions to be made on the related Distribution Date. Any of this
Overcollateralization Reduction Amount shall be distributed as part of Net
Monthly Excess Cashflow pursuant to the priorities set forth above. This has the
effect of decelerating the amortization of the offered certificates relative to
the amortization of the mortgage loans and of reducing the Overcollateralized
Amount.


                                      S-34


FINANCIAL GUARANTY INSURANCE POLICY

         The following summary of the terms of the Policy does not purport to be
complete and is qualified in its entirety by reference to the Policy. A form of
the Policy may be obtained, upon request, from the depositor.

         Simultaneously with the issuance of the offered certificates, the
insurer will deliver the Policy to the Trust Administrator for the benefit of
the holders of the offered certificates. Under the Policy, the insurer will
irrevocably and unconditionally guarantee payment to the Trust Administrator on
behalf of the Trustee on each Distribution Date for the benefit of the holders
of the offered certificates, the full and complete payment of Insured Payments
with respect to the offered certificates calculated in accordance with the
original terms of the offered certificates when issued and without regard to any
amendment or modification of the offered certificates or the Agreement except
amendments or modifications to which the insurer has given its prior written
consent.

         If any Insured Payment is avoided as a preference payment under
applicable bankruptcy, insolvency, receivership or similar law, the insurer will
pay this amount out of funds of the insurer on the later of (1) the date when
due to be paid pursuant to the Order referred to below or (2) the first to occur
of (a) the a fourth Business Day following Receipt by the insurer from the Trust
Administrator of (A) a certified copy of the order of the court or other
governmental body which exercised jurisdiction to the effect that a holder of
offered certificates is required to return principal or interest distributed
with respect to an Offered Certificate during the Term of the Policy because
these distributions were avoidable preferences under applicable bankruptcy law,
(B) a certificate of the holder of offered certificates that the Order has been
entered and is not subject to any stay, and (C) an assignment duly executed and
delivered by the holder of offered certificates, in the form as is reasonably
required by the insurer and provided to the holder of offered certificates by
the insurer, irrevocably assigning to the insurer all rights and claims of the
holder of offered certificates relating to or arising under the offered
certificates against the debtor which made the preference payment or otherwise
with respect to the preference payment, or (b) the date of Receipt by the
insurer from the Trust Administrator of the items referred to in clauses (A),
(B) and (C) above if, at least four Business Days prior to the date of Receipt,
the insurer shall have Received written notice from the Trust Administrator that
the items were to be delivered on a specified date and the date was specified in
the notice. The payment shall be disbursed to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order and not to the
Trust Administrator or holder of offered certificates directly, unless a holder
of offered certificates has previously paid the amount to the receiver,
conservator, debtor-in-possession or trustee in bankruptcy named in the Order,
in which case the payment shall be disbursed to the Trust Administrator for
distribution to the holder of the offered certificates upon proof of the payment
reasonably satisfactory to the insurer. In connection with the foregoing, the
insurer shall have the rights provided pursuant to the Agreement.

         Payment of claims under the Policy made in respect of Insured Payments
will be made by the insurer following Receipt by the insurer of the appropriate
notice for payment on the later to occur of (a) 12:00 noon, New York City time,
on the second Business Day following Receipt of the notice for payment, and (b)
12:00 noon, New York City time, on the relevant Distribution Date.

         The insurer's obligations under the Policy to make Insured Payments
shall be discharged to the extent funds are transferred to the Trust
Administrator as provided in the Policy, whether or not the funds are properly
applied by the Trust Administrator.

         The insurer shall be subrogated to the rights of the holders of the
offered certificates to receive payments of principal and interest, as
applicable, with respect to distributions on the Certificates to the extent of
any payment by the insurer under the Policy. To the extent the insurer makes
Insured Payments,


                                      S-35


either directly or indirectly (as by paying through the Trust Administrator), to
the holders of the offered certificates, the insurer will be subrogated to the
rights of the holders of the offered certificates, as applicable, with respect
to the Insured Payment and shall be deemed to the extent of the payments so made
to be a registered holder of the offered certificates for purposes of payment.

         Claims under the Policy constitute direct unsecured and unsubordinated
obligations of the insurer, and will rank not less than PARI PASSU with any
other unsecured and unsubordinated indebtedness of the insurer except for some
obligations with respect to tax and other payments to which preference is or may
become afforded by statute. The terms of the Policy cannot be modified, altered
or affected by any other agreement or instrument, or by the merger,
consolidation or dissolution of the depositor. The Policy by its terms may not
be canceled or revoked prior to distribution in full of all Guaranteed
Distributions (as defined in the Policy). The Policy is governed by the laws of
the State of New York. The Policy is not covered by the property/casualty
insurance security fund specified in Article 76 of the New York Insurance Law.

         To the fullest extent permitted by applicable law, the insurer agrees
under the Policy not to assert, and waives, for the benefit of each holder of
the offered certificates, all its rights (whether by counterclaim, setoff or
otherwise) and defenses (including the defense of fraud), whether acquired by
subrogation, assignment or otherwise, to the extent that these rights and
defenses may be available to the insurer to avoid payment of its obligations
under the Policy in accordance with the express provisions of the Policy.

         Pursuant to the terms of the Agreement, unless an Insurer Default
exists, the insurer will be entitled to exercise certain rights of the holders
of the offered certificates, without the consent of the certificateholders, and
the holders of the offered certificates may exercise the rights only with the
prior written consent of the insurer. SEE "POOLING AND SERVICING
AGREEMENT--VOTING RIGHTS" AND "--CERTAIN MATTERS REGARDING THE INSURER" IN THIS
PROSPECTUS SUPPLEMENT.

         The depositor, the Sponsor, the Servicers and the insurer will enter
into an Insurance Agreement pursuant to which the depositor, the Sponsor and the
Servicers will agree to reimburse, with interest, the insurer for amounts paid
pursuant to claims under the Policy. The depositor, the Sponsor and the
Servicers will further agree to pay the insurer all reasonable charges and
expenses which the insurer may pay or incur relative to any amounts paid under
the Policy or otherwise in connection with the transaction and to indemnify the
insurer against some liabilities. Except to the extent provided in the Insurance
Agreement, amounts owing under the Insurance Agreement will be payable solely
from the trust fund. An event of default by either Servicer under the Insurance
Agreement will constitute an Event of Default by the Servicer under the
Agreement and allow the insurer, among other things, to direct the Trustee to
terminate the Servicer. An "event of default" by each Servicer under the
Insurance Agreement includes (1) the Servicer's failure to pay when due any
amount owed under the Insurance Agreement or other documents, (2) the Servicer's
untruth or incorrectness in any material respect of any representation or
warranty of the Servicer in the Insurance Agreement, the Agreement (in its
capacity as Servicer) or other documents, (3) the Servicer's failure to perform
or to observe any covenant or agreement in the Insurance Agreement, the
Agreement (in its capacity as Servicer) and other documents, (4) the Servicer's
failure to pay its debts in general or the occurrence of certain events of
insolvency or bankruptcy with respect to the Servicer and (5) the occurrence of
an Event of Default relating to the Servicer under the Agreement or other
documents.

         [Additional information with respect to credit enhancement providers,
required pursuant to Item 1114(b) of Regulation AB, will be provided if
applicable.]


                                      S-36


TABLE OF FEES AND EXPENSES

         The following table indicates the fees and expenses to be paid from the
cash flows from the mortgage loans and other assets of the trust fund, while the
Certificates are outstanding.

         All fees are expressed in basis points, at an annualized rate, applied
to the outstanding aggregate principal balance of the mortgage loans.

                 ITEM                 FEE                PAID FROM
       --------------------------   -------   ----------------------------------
       Master Servicing Fee(1)(2)    ___bp    Mortgage Loan Interest Collections
       Trustee Fee                   ___bp    Master Servicing Fee
       Servicer Fee                  ___bp    Master Servicing Fee

       (1) Master servicing fee including trustee and certificate registrar
           fees. The Master Servicer receives a single combined fee that covers
           all of these functions. The Master Servicer performs these functions.
       (2) Master Servicer pays trustee and servicer fees out of its fee.
       (3) The master servicing fee is paid on a first priority basis
           from collections allocable to interest on the mortgage loans,
           prior to distributions to certificateholders.


ALLOCATION OF LOSSES; SUBORDINATION

         With respect to any defaulted mortgage loan that is finally liquidated
through foreclosure sale, disposition of the related mortgaged property (if
acquired on behalf of the certificateholders by deed in lieu of foreclosure) or
otherwise, the amount of loss realized, if any, will equal the portion of the
unpaid principal balance remaining, if any, plus interest through the last day
of the month in which the mortgage loan was finally liquidated, after
application of all amounts recovered (net of amounts reimbursable to the
Servicers for P&I Advances, servicing advances and other related expenses,
including attorney's fees) towards interest and principal owing on the mortgage
loan. In the event that amounts recovered in connection with the final
liquidation of a defaulted mortgage loan are insufficient to reimburse the
Servicers for P&I Advances and servicing advances, these amounts may be
reimbursed to the Servicers out of any funds in the Certificate Account prior to
the distribution on the Certificates.

         Any Realized Losses on the mortgage loans will be allocated on any
Distribution Date, first, to Net Monthly Excess Cashflow, second, to the Class
CE Certificates until the Certificate Principal Balance thereof has been reduced
to zero, and third, to the offered certificates on a PRO RATA basis. The
Agreement does not permit the allocation of any Realized Losses to the Class P
Certificates. The Policy will cover any Realized Losses allocable to the offered
certificates pursuant to clause third above. Notwithstanding the foregoing,
however, if payments are not made as required under the Policy, Realized Losses
will be allocated to the offered certificates.

         If Realized Losses have been allocated to the offered certificates and
the insurer has defaulted in its obligation to cover these Realized Losses,
these amounts with respect to the Certificates will no longer accrue interest
nor will the amounts be reinstated thereafter (even if Net Monthly Excess
Cashflow and/or the Overcollateralized Amount are greater than zero on any
subsequent Distribution Dates).

         Any allocation of a Realized Loss to a Certificate will be made by
reducing the Certificate Principal Balance thereof by the amount so allocated as
of the Distribution Date in the month following the calendar month in which the
Realized Loss was incurred. An allocation of a Realized Loss on a PRO RATA basis
between two or more classes of Certificates means an allocation to each of the
classes of Certificates on the basis of its then outstanding Certificate
Principal Balance prior to giving effect to distributions to be made on the
related Distribution Date. Notwithstanding anything to the contrary


                                      S-37


described in this prospectus supplement, in no event will the Certificate
Principal Balance of an Offered Certificate be reduced more than once in respect
of any particular amount both (1) allocable to the Offered Certificate in
respect of Realized Losses and (2) payable as principal to the holder of the
Offered Certificate from Net Monthly Excess Cashflow or from amounts paid under
the Policy.

P&I ADVANCES

         Subject to the following limitations, each Servicer will be obligated
to advance or cause to be advanced on or before each Distribution Date its own
funds, or funds in the Certificate Account that are not included in the
Available Distribution Amount for the Distribution Date, in an amount equal to
the aggregate of all payments of principal and interest, net of the Servicing
Fee, that were due during the related Due Period on the mortgage loans serviced
by it and that were delinquent on the related Determination Date, plus some
amounts representing assumed payments not covered by any current net income on
the mortgaged properties acquired by foreclosure or deed in lieu of foreclosure.
With respect to a delinquent Balloon Payment, the related Servicer is not
required to make a P&I Advance of the delinquent Balloon Payment. The related
Servicer will, however, make monthly P&I Advances with respect to a Balloon Loan
with delinquent Balloon Payments, in each case in an amount equal to the assumed
monthly principal and interest payment (net of the related Servicing Fee) that
would have been due during the related Due Period based on the original
principal amortization schedule for the Balloon Loan.

         P&I Advances are required to be made only to the extent they are deemed
by the applicable Servicer to be recoverable from related late collections,
insurance proceeds or liquidation proceeds. The purpose of making the P&I
Advances is to maintain a regular cash flow to the certificateholders, rather
than to guarantee or insure against losses. Neither Servicer will be required to
make any P&I Advances with respect to reductions in the amount of the monthly
payments on the mortgage loans due to bankruptcy proceedings or the application
of the Relief Act.

         All P&I Advances will be reimbursable to the applicable Servicer from
late collections, insurance proceeds and liquidation proceeds from the mortgage
loan serviced by it as to which the unreimbursed P&I Advance was made. In
addition, any P&I Advances previously made in respect of any mortgage loan that
are deemed by applicable Servicer to be nonrecoverable from related late
collections, insurance proceeds or liquidation proceeds may be reimbursed to the
Servicer out of any funds in the Certificate Account prior to the distributions
on the Certificates. In the event that either Servicer fails in its obligation
to make any required advance, the Trust Administrator will be obligated to make
any related advance and in the event that the Trust Administrator fails in its
obligation to make any related advance, the Trustee will be obligated to make
any related advance, in each case to the extent required in the Agreement.
Notwithstanding the foregoing, in the event _______ fails in its obligation to
make any required advance as Servicer, the Master Servicer will be obligated to
make any related advance prior to the obligation of the Trust Administrator or
the Trustee to make the related advances as provided above.

THE MASTER SERVICER AND THE SERVICERS

GENERAL

         Impac Funding Corporation, referred to in this prospectus supplement as
Impac Funding Corporation or the Master Servicer, will act as the Master
Servicer of the mortgage loans pursuant to the Pooling and Servicing Agreement,
referred to herein as the Agreement, dated as of the Cut-off Date, among the
Depositor, the Sponsor, the Master Servicer and the Trustee.

         Primary servicing of the mortgage loans will be provided for in
accordance with the Pooling and Servicing Agreement or similar agreements, which
are collectively referred to in this prospectus supplement as the Servicing
Agreements. Each of the Servicing Agreements will be assigned to the trust
pursuant to various assignment, assumption and recognition agreements among the
related Servicer, the Sponsor and the Trustee on behalf of the
Certificateholders; provided, however, that the Sponsor will retain the right to
enforce the representations and warranties made by the Servicers with respect to
the related mortgage loans against them. In the event of a default by a Servicer
under the related Servicing Agreement, the Master Servicer will be required to
enforce any remedies against the Servicer, and shall either find a successor
Servicer or shall assume primary servicing obligations for the related mortgage
loans itself.

         The Servicer or the Master Servicer, directly or through subservicers,
as the case may be, will make reasonable efforts to collect all payments called
for under the loans and will, consistent with the related servicing agreement
and any applicable insurance policy, FHA insurance or other credit enhancement,
follow the collection procedures that are normal and usual in its general loan
servicing activities for assets that are comparable to the loans. Consistent
with the previous sentence, the Servicer or the Master Servicer may, in its
discretion, waive any prepayment charge in connection with the prepayment of a
loan or extend the due dates for payments due on a mortgage note, provided that
the insurance coverage for the loan or any coverage provided by any alternative
credit enhancement will not be adversely affected by the waiver or extension.
The Master Servicer or Servicer may also waive or modify any term of a loan so
long as the Master Servicer or Servicer has determined that the waiver or
modification is not materially adverse to any securityholders, taking into
account any estimated loss that may result absent that action.

         In instances in which a loan is in default, or if default is reasonably
foreseeable, and if determined by the Master Servicer or Servicer to be in the
best interests of the related securityholders, the Master


                                      S-41


Servicer or Servicer may engage, either directly or through subservicers, in a
wide variety of loss mitigation practices including waivers, modifications,
payment forbearances, partial forgiveness, entering into repayment schedule
arrangements, and capitalization of arrearages rather than proceeding with
foreclosure or repossession, if applicable. In making that determination, the
estimated Realized Loss that might result if the loan were liquidated would be
taken into account. Modifications may have the effect of, among other things,
reducing the loan rate, forgiving payments of principal, interest or other
amounts owed under the mortgage loan or contract, such as taxes or insurance
premiums, extending the final maturity date of the loan, capitalizing delinquent
interest and other amounts owed under the mortgage loan or contract, or any
combination of these or other modifications. Any modified loan may remain in the
related trust, and the reduction in collections resulting from a modification
may result in reduced distributions of interest or principal on, or may extend
the final maturity of, one or more classes of the related securities.

         The Servicers will be responsible for the servicing of the mortgage
loans covered by the related Servicing Agreement, and the Master Servicer will
be required to monitor their performance. All collections of principal and
interest on any mortgage loans, including but not limited to Principal
Prepayments, Insurance Proceeds, Liquidation Proceeds (less amounts reimbursable
to the applicable Servicer out of Liquidation Proceeds in accordance with the
applicable Servicing Agreement), the Repurchase Price for any mortgage loans
repurchased, and advances made from the Servicer's own funds (less the servicing
fee) will be deposited in a Protected Account, held by a designated depository
institution and segregated on the books of such institution in the name of the
Trustee for the benefit of Certificateholders. Amounts on deposit in a Protected
Account may be invested in Permitted Investments in the name of the Trustee for
the benefit of Certificateholders and, except as provided in the preceding
paragraph, not commingled with any other funds. Such Permitted Investments shall
mature, or shall be subject to redemption or withdrawal, no later than the date
on which such funds are required to be withdrawn for deposit in the Master
Servicer Collection Account, and shall be held until required for such deposit.
The income earned from Permitted Investments made shall be paid to the related
Servicer under the applicable Servicing Agreement, and the risk of loss of
moneys required to be distributed to the Certificateholders resulting from such
investments shall be borne by and be the risk of the related Servicer. The
related Servicer (to the extent provided in the Servicing Agreement) shall
deposit the amount of any such loss in the Protected Account within two Business
Days of receipt of notification of such loss but not later than the second
Business Day prior to the Distribution Date on which the moneys so invested are
required to be distributed to the Certificateholders. On the date specified in
the related Servicing Agreement, the related Servicer will withdraw or cause to
be withdrawn from the applicable Protected Accounts and any other permitted
accounts and will remit to the Master Servicer for deposit in the Master
Servicer Collection Account the Available Funds. SEE "DESCRIPTION OF THE
SECURITIES-THE DISTRIBUTION ACCOUNT" IN THE PROSPECTUS.

         The information set forth in the following paragraphs with respect to
the Master Servicer and the Servicers has been provided by the respective party.

OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS

         The Master Servicer has the option to purchase from the trust fund any
mortgage loan that is 90 days or more delinquent, which the Master Servicer
determines in good faith will otherwise become subject to foreclosure
proceedings; provided, however, that (1) the Master Servicer shall purchase any
of these mortgage loans on the basis of delinquency, purchasing the most
delinquent mortgage loans first and (2) after it has purchased __% of the
mortgage loans, by aggregate principal balance as of the Cut-off Date, pursuant
to clause (1) above, the Master Servicer must also obtain the consent of the
insurer prior to any further purchases of delinquent mortgage loans.
Notwithstanding the foregoing, prior to purchasing any mortgage loan serviced by
___________, the Master Servicer must give ___________ the right of first
refusal to purchase the mortgage loan.

EVENTS OF DEFAULT

         In addition to those events of default described under "Description of
the Securities--Events of Default" in the prospectus, upon the occurrence of
loss and delinquency triggers with respect to the mortgage loans serviced by the
related Servicer or upon the occurrence of certain other defaults which are set
forth in the Agreement, each Servicer may be removed as servicer of the mortgage
loans in accordance with the terms of the Agreement and the Insurance Agreement.
In addition, if ______________ is terminated in its capacity as Servicer under
the Agreement, it shall also be terminated as Master Servicer.

         Pursuant to the Agreement, each Servicer covenants and agrees to act as
a Servicer for an initial term from the Closing Date to __________ __, ____,
which term shall be extendable by the insurer for successive terms of three (3)
calendar months thereafter, until the termination of the trust fund. Each notice
of extension shall be delivered by the insurer to the Trustee, the Trust
Administrator and the related Servicer. Each Servicer will, upon its receipt of
the notice of extension, become bound for the duration of the term covered by
the notice of extension to continue as a Servicer subject to and in accordance
with the other provisions of the Agreement. If as of the fifteenth (15th) day
prior to the last day of any term of the Servicer, the Trust Administrator shall
not have received any notice of extension from the insurer, the Trust
Administrator will, within five (5) days thereafter, give written notice of the
non-receipt to the insurer, the related Servicer and the Trustee. The failure of
the insurer to deliver a notice of extension by the end of a calendar term shall
result in the termination of the related Servicer.

         Any successor to either Servicer appointed under the Agreement must be
a housing loan servicing institution acceptable to each Rating Agency (as
defined in the prospectus) with a net worth at the time of the appointment of at
least $15,000,000. SEE "DESCRIPTION OF THE SECURITIES--RIGHTS UPON EVENT OF
DEFAULT" IN THE PROSPECTUS.

                              PERMITTED INVESTMENTS

         Any institution maintaining a custodial account shall at the direction
of the Master Servicer invest the funds in such account in Permitted
Investments, each of which shall mature not later than (i) the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to the Pooling and Servicing Agreement, if a Person
other than the Trustee is the obligor thereon, and (ii) no later than the date
on which such funds are required to be withdrawn from such account pursuant to
the Pooling and Servicing Agreement, if the Trustee is the obligor thereon and
shall not be sold or disposed of prior to its maturity. All income and gain
realized from any such investment as well as any interest earned on deposits in
a custodial account shall be for the benefit of the Master Servicer. The Master
Servicer shall deposit in a custodial account an amount equal to the amount of
any loss incurred in respect of any such investment immediately upon realization
of such loss without right of reimbursement.

         Any one or more of the following obligations or securities held in the
name of the Trustee for the benefit of the Certificateholders will be considered
a Permitted Investment:

         (i) obligations of or guaranteed as to principal and interest by the
United States or any agency or instrumentality thereof when such obligations are
backed by the full faith and credit of the United States;

         (ii) repurchase agreements on obligations specified in clause (i)
maturing not more than one month from the date of acquisition thereof, provided
that the unsecured obligations of the party agreeing to repurchase such
obligations are at the time rated by each Rating Agency in its highest
short-term rating available;


                                      S-48


         (iii) federal funds, certificates of deposit, demand deposits, time
deposits and bankers' acceptances (which shall each have an original maturity of
not more than 90 days and, in the case of bankers' acceptances, shall in no
event have an original maturity of more than 365 days or a remaining maturity of
more than 30 days) denominated in United States dollars of any U.S. depository
institution or trust company incorporated under the laws of the United States or
any state thereof or of any domestic branch of a foreign depository institution
or trust company; provided that the debt obligations of such depository
institution or trust company (or, if the only Rating Agency is Standard &
Poor's, in the case of the principal depository institution in a depository
institution holding company, debt obligations of the depository institution
holding company) at the date of acquisition thereof have been rated by each
Rating Agency in its highest short-term rating available; and provided further
that, if the only Rating Agency is Standard & Poor's and if the depository or
trust company is a principal subsidiary of a bank holding company and the debt
obligations of such subsidiary are not separately rated, the applicable rating
shall be that of the bank holding company; and, provided further that, if the
original maturity of such short-term obligations of a domestic branch of a
foreign depository institution or trust company shall exceed 30 days, the
short-term rating of such institution shall be A-1+ in the case of Standard &
Poor's if Standard & Poor's is the Rating Agency;

         (iv) commercial paper (having original maturities of not more than 365
days) of any corporation incorporated under the laws of the United States or any
state thereof which on the date of acquisition has been rated by Moody's and
Standard & Poor's in their highest short-term ratings available; provided that
such commercial paper shall have a remaining maturity of not more than 30 days;

         (v) a money market fund or a qualified investment fund rated by Moody's
in its highest long-term ratings available and rated AAAm or AAAm-G by Standard
& Poor's, including any such funds for which ___________ or any affiliate
thereof serves as an investment advisor, manager, administrator, shareholder,
servicing agent, and/or custodian or sub-custodian; and

         (vi) other obligations or securities that are acceptable to each Rating
Agency as a Permitted Investment hereunder and will not reduce the rating
assigned to any Class of Certificates by such Rating Agency below the lower of
the then-current rating or the rating assigned to such Certificates as of the
Closing Date by such Rating Agency, as evidenced in writing;

provided, however, that no instrument shall be a Permitted Investment if it
represents, either (1) the right to receive only interest payments with respect
to the underlying debt instrument or (2) the right to receive both principal and
interest payments derived from obligations underlying such instrument and the
principal and interest payments with respect to such instrument provide a yield
to maturity greater than 120% of the yield to maturity at par of such underlying
obligations.

                                   TERMINATION

         The circumstances under which the obligations created by the Agreement
will terminate in respect of the Certificates are described in "Description of
the Securities--Termination" in the prospectus. The majority holder of the Class
CE Certificates (or if the holder does not exercise the option, the Master
Servicer or the insurer) will have the right to purchase all remaining mortgage
loans and any properties acquired in respect thereof and thereby effect early
retirement of the Certificates on any Distribution Date following the Due Period
during which the aggregate principal balance of the mortgage loans (and
properties acquired in respect thereof) remaining in the trust fund at the time
of purchase is reduced to less than __%, in the event the majority holder of the
Class CE Certificates exercises the option, or __%, in the event the Master
Servicer or the insurer exercises the option, of the aggregate principal balance
of the mortgage loans as of the Cut-off Date. In the event the majority holder
of the Class CE Certificates exercises the option, the purchase price payable in
connection therewith generally


                                      S-49


will be equal to par, and in the event the Master Servicer or the insurer
exercises the option, the purchase price payable in connection therewith
generally will be equal to the greater of par or the fair market value of the
mortgage loans and the properties, in each case plus accrued interest for each
mortgage loan at the related mortgage rate to but not including the first day of
the month in which the repurchase price is distributed, together with any
amounts due to the Servicers for unpaid Servicing Fees and any unreimbursed
advances and any amounts due to ___________, in its capacity as Master Servicer
for any unpaid Master Servicing Fees. In the event the majority holder of the
Class CE Certificates or the Master Servicer or the insurer exercises the
option, the portion of the purchase price allocable to the offered certificates
will be, to the extent of available funds (including funds paid under the
Policy), (1) 100% of the then outstanding Certificate Principal Balance, plus
(2) one month's interest on the then outstanding Certificate Principal Balance
at the then applicable Pass-Through Rate for the class, plus (3) any previously
accrued but unpaid interest to which the holders of the Certificates are
entitled. The holders of the Residual Certificates shall pledge any amount
received in a termination in excess of par to the holders of the Class CE
Certificates. In no event will the trust created by the Agreement continue
beyond the expiration of 21 years from the death of the survivor of the persons
named in the Agreement. SEE "DESCRIPTION OF THE SECURITIES--TERMINATION" IN THE
PROSPECTUS.

INSURANCE REGULATION

         The insurer is licensed and subject to regulation as a financial
guaranty insurance corporation under the laws of the State of New York, its
state of domicile. In addition, the insurer and its insurance subsidiaries are
subject to regulation by insurance laws of the various other jurisdictions in
which they are licensed to do business. As a financial guaranty insurance
corporation licensed to do business in the State of New York, the insurer is
subject to Article 69 of the New York Insurance Law which, among other things,
limits the business of each insurer to financial guaranty insurance and related
lines, requires that each insurer maintain a minimum surplus to policyholders,
establishes contingency, loss and unearned premium reserve requirements for each
insurer, and limits the size of individual transactions ("single risks") and the
volume of transactions ("aggregate risks") that may be underwritten by each
insurer. Other provisions of the New York Insurance Law, applicable to non-life
insurance companies such as the insurer, regulate, among other things, permitted
investments, payment of dividends, transactions with affiliates, mergers,
consolidations, acquisitions or sales of assets and incurrence of liability for
borrowings.

                         FEDERAL INCOME TAX CONSEQUENCES

         Three separate elections will be made to treat the trust fund as real
estate mortgage investment conduits ("REMIC I", "REMIC II" and "REMIC III",
respectively) for federal income tax purposes. Upon the issuance of the offered
certificates, Thacher Proffitt & Wood LLP, counsel to the depositor, will
deliver its opinion generally to the effect that, assuming compliance with all
provisions of the Agreement, for federal income tax purposes, each of REMIC I,
REMIC II and REMIC III will qualify as a REMIC under Sections 860A through 860G
of the Internal Revenue Code of 1986.

         For federal income tax purposes, (1) the Class R-I Certificates will be
the sole class of "residual interests" in REMIC I, (2) separate non-certificated
regular interests in REMIC I will be issued and will be the "regular interests"
in REMIC I, (3) the Class R-II Certificates will be the sole class of "residual
interests" in REMIC II, (4) separate non-certificated regular interests in REMIC
II will be issued and will be the "regular interests" in REMIC II, (5) the Class
R-III Certificates will be the sole class of "residual interests" in REMIC III,
and (6) the offered certificates, the Class CE Certificates and the Class P
Certificates will be the "regular interests" in, and will be treated as debt
instruments of, REMIC III. SEE "FEDERAL INCOME TAX
CONSEQUENCES--REMIC--CLASSIFICATION OF REMICS" IN THE PROSPECTUS.

         For federal income tax reporting purposes, the offered certificates
will not be treated as having been issued with original issue discount. The
prepayment assumption that will be used in determining the


                                      S-52


rate of accrual of original issue discount, premium and market discount, if any,
for federal income tax purposes will be based on the assumption that subsequent
to the date of any determination the mortgage loans will prepay at a constant
rate equal to ___% of the Prepayment Vector. No representation is made that the
mortgage loans will prepay at the above rate or at any other rate. SEE "FEDERAL
INCOME TAX CONSEQUENCES--REMICS--TAXATION OF OWNERS OF REMIC REGULAR
CERTIFICATES--ORIGINAL ISSUE DISCOUNT" IN THE PROSPECTUS.

         The Internal Revenue Service has issued regulations under Sections 1271
to 1275 of the Code generally addressing the treatment of debt instruments
issued with original issue discount. The OID Regulations in some circumstances
permit the holder of a debt instrument to recognize original issue discount
under a method that differs from that of the Issuing Entity. Accordingly, it is
possible that holders of offered certificates issued with original issue
discount may be able to select a method for recognizing original issue discount
that differs from that used in preparing reports to certificateholders and the
IRS. Prospective purchasers of offered certificates issued with original issue
discount are advised to consult their tax advisors concerning the tax treatment
of the Certificates in this regard.

         The offered certificates may be treated for federal income tax purposes
as having been issued at a premium. Whether any holder of a Offered Certificate
will be treated as holding a Certificate with amortizable bond premium will
depend on the certificateholder's purchase price and the distributions remaining
to be made on the Certificate at the time of its acquisition by the
certificateholder. Holders of offered certificates should consult their own tax
advisors regarding the possibility of making an election to amortize the
premium. SEE "FEDERAL INCOME TAX CONSEQUENCES-- REMICS--TAXATION OF OWNERS OF
REMIC REGULAR CERTIFICATES--PREMIUM" IN THE PROSPECTUS.

         The offered certificates will be treated as assets described in Section
7701(a)(19)(C) of the Code and "real estate assets" under Section 856(c)(4)(A)
of the Code, generally in the same proportion that the assets in the trust fund
would be so treated. In addition, interest on the offered certificates will be
treated as "interest on obligations secured by mortgages on real property" under
Section 856(c)(3)(B) of the Code, generally to the extent that the offered
certificates are treated as "real estate assets" under Section 856(c)(4)(A) of
the Code. The offered certificates will also be treated as "qualified mortgages"
under Section 860G(a)(3) of the Code. SEE "FEDERAL INCOME TAX CONSEQUENCES--
REMICS--CHARACTERIZATION OF INVESTMENTS IN REMIC CERTIFICATES" IN THE
PROSPECTUS.

         It is not anticipated that any of REMIC I, REMIC II or REMIC III will
engage in any transactions that would subject it to the prohibited transactions
tax as defined in Section 860F(a)(2) of the Code, the contributions tax as
defined in Section 860G(d) of the Code or the tax on net income from foreclosure
property as defined in Section 860G(c) of the Code. However, in the event that
any of the above-mentioned taxes are imposed on REMIC I, REMIC II or REMIC III,
the tax will be borne (1) by the Trust Administrator, if the Trust Administrator
has breached its obligations with respect to REMIC compliance under the
Agreement, (2) by __________, if ____________, in its capacity as Master
Servicer or as a Servicer, has breached its obligations with respect to REMIC
compliance under the Agreement, (3) by ___________, if ___________, in its
capacity as a Servicer has breached its obligations with respect to REMIC
compliance under the Agreement, (4) by the Trustee, if the Trustee has breached
its obligations with respect to REMIC compliance under the Agreement and (5)
otherwise by the trust fund, with a resulting reduction in amounts otherwise
distributable to holders of the related offered certificates. SEE "DESCRIPTION
OF THE SECURITIES-- GENERAL" AND "FEDERAL INCOME TAX
CONSEQUENCES--REMICS--PROHIBITED TRANSACTIONS AND OTHER POSSIBLE REMIC TAXES" IN
THE PROSPECTUS.

         The responsibility for filing annual federal information returns and
other reports will be borne by the Trustee, the Trust Administrator or the
Master Servicer. SEE "FEDERAL INCOME TAX CONSEQUENCES--REMICS-- REPORTING AND

                             METHOD OF DISTRIBUTION

         Subject to the terms and conditions set forth in the Underwriting
Agreement, dated _________ __, ____, the depositor has agreed to sell, and [Name
of Underwriter] has agreed to purchase the offered certificates. The Underwriter
is obligated to purchase all offered certificates if it purchases any. The
Underwriter is an affiliate of the depositor.

         Distribution of the offered certificates will be made from time to time
in negotiated transactions or otherwise at varying prices to be determined at
the time of sale. Proceeds to the depositor from the sale of the offered
certificates, before deducting expenses payable by the depositor, will be 99.50%
of the aggregate initial Certificate Principal Balance of the offered
certificates, plus accrued interest. In connection with the purchase and sale of
the offered certificates, the Underwriter may be deemed to have received
compensation from the depositor in the form of underwriting discounts.

         The offered certificates are offered subject to receipt and acceptance
by the Underwriter, to prior sale and to the Underwriter's right to reject any
order in whole or in part and to withdraw, cancel or modify the offer without
notice. It is expected that delivery of the offered certificates will be made
through the facilities of the DTC on or about the Closing Date.

         The Underwriting Agreement provides that the depositor will indemnify
the Underwriter against some civil liabilities, including liabilities under the
Securities Act of 1933, as amended, or will contribute to payments the
Underwriter may be required to make in respect thereof.

                                SECONDARY MARKET

         There is currently no secondary market for the offered certificates and
there can be no assurance that a secondary market for the offered certificates
will develop or, if it does develop, that it will continue. The Underwriter
intends to establish a market in the offered certificates but it is not
obligated to do so. The primary source of information available to investors
concerning the offered certificates will be the monthly statements discussed in
the prospectus under "Description of the Securities--Reports to
Certificateholders", which will include information as to the outstanding
principal balance of the offered certificates and the status of the applicable
form of credit enhancement. There can be no assurance that any additional
information regarding the offered certificates will be available through any
other source. In addition, the depositor is not aware of any source through
which price information about the offered certificates will be generally
available on an ongoing basis. The limited nature of the information regarding
the offered certificates may adversely affect the liquidity of the offered
certificates, even if a secondary market for the offered certificates becomes
available.

                                 LEGAL OPINIONS

         Some legal matters relating to the offered certificates will be passed
upon for the depositor and the Underwriter by Thacher Proffitt & Wood LLP, New

supplement, have been incorporated in this


                                      S-54


prospectus supplement in reliance on the report of _______________, independent
accountants, given on the authority of that firm as experts in accounting and
auditing.

                                LEGAL PROCEEDINGS

         [There are no material legal proceedings pending against the Sponsor,
the Depositor, the Trustee, The Issuing Entity, the Master Servicer, [any
affiliated Servicer, any 20% concentration unaffiliated Servicer, any 20%
concentration Originator], the Custodians, or with respect to which the property
of any of the foregoing transaction parties is subject, that are material to the
Certificateholders. No legal proceedings against any of the foregoing
transaction parties is known to be contemplated by governmental authorities,
that are material to the Certificateholders.]

              AFFILIATIONS, RELATIONSHIPS AND RELATED TRANSACTIONS

         [There are no affiliations between the Sponsor, the Depositor or the
Issuing Entity and any of the Master Servicer, [any affiliated Servicer, any 20%
concentration unaffiliated Servicer], the Trustee, [any 10% concentration
Originator], [any credit enhancement provider or derivatives counterparty], the
Custodians. There are no affiliations among the Master Servicer, [any affiliated
Servicer, any 20% concentration unaffiliated Servicer], the Trustee, [any 10%
concentration Originator], [any credit enhancement provider or derivatives
counterparty], the Custodians. There are currently no business relationships,
agreements, arrangements, transactions or understandings between (a) the
Sponsor, the Depositor or the Issuing Entity and (b) any of the parties referred
to in the preceding sentence, or any of their respective affiliates, that were
entered into outside the normal course of business or that contain terms other
than would be obtained in an arm's length transaction with an unrelated third
party and that are material to the investor's understanding of the Certificates,
or that relate to the Certificates or the pooled assets. No such business
relationship, agreement, arrangement, transaction or understanding has existed
during the past two years.]

                                     RATINGS

         It is a condition to the issuance of the Certificates that the offered
certificates be rated "Aaa" by ____________ and "AAA" by _____________.

         The ratings of ________ and ___________ assigned to mortgage
pass-through certificates address the likelihood of the receipt by
certificateholders of all distributions to which the certificateholders are
entitled. The rating process addresses structural and legal aspects associated
with the Certificates, including the nature of the underlying mortgage loans.
The ratings assigned to mortgage pass-through certificates do not represent any
assessment of the likelihood that principal prepayments will be made by the
mortgagors or the degree to which the prepayments will differ from that
originally anticipated. The ratings assigned by __________ and _________ on the
offered certificates are based in part upon the insurer's claims paying ability.
Any change in the ratings of the insurer by _________ or ___________ may result
in a change in the ratings on the offered certificates. The ratings do not
address the possibility that certificateholders might suffer a lower than
anticipated yield due to non-credit events.

         A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning rating organization. Each security rating should be evaluated
independently of any other security rating. In the event that the ratings
initially assigned to the offered certificates are subsequently lowered for any
reason, no person or entity is obligated to provide any additional credit
support or credit enhancement with respect to the offered certificates.


                                      S-55


         The depositor has not requested that any rating agency rate the offered
certificates other than as stated above. However, there can be no assurance as
to whether any other rating agency will rate the offered certificates, or, if it
does, what rating would be assigned by any other rating agency. A rating on the
offered certificates by another rating agency, if assigned at all, may be lower
than the ratings assigned to the offered certificates as stated above.

         The rating agencies have stated that it is their standard policy to
monitor ratings on publicly offered securities for which a rating has been
provided, as to each rating agency rating each class of Offered Certificates in
accordance with the rating agencies' particular surveillance policies, unless
the Issuing Entity requests a rating without surveillance. A rating agency will
monitor the rating it issues on an ongoing basis and may update the rating after
conducting its regular review of the Issuing Entity's creditworthiness or after
conducting a review of the status of the rating upon becoming aware of any
information that might reasonably be expected to result in a change of rating.
The Depositor has not requested that any rating agency not monitor their ratings
of the Offered Certificates, and the Depositor has not requested that any rating
agency use any monitoring procedures other than their standard monitoring
procedures.

                                LEGAL INVESTMENT

         The offered certificates will not constitute "mortgage related
securities" for purposes of the Secondary Mortgage Market Enhancement Act of
1984 because the mortgage pool includes some mortgage loans that are secured by
subordinate liens on the related mortgaged properties

         The depositor makes no representations as to the proper
characterization of any class of offered certificates for legal investment or
other purposes, or as to the ability of particular investors to purchase any
class of offered certificates under applicable legal investment restrictions.
These uncertainties may adversely affect the liquidity of any class of offered
certificates. Accordingly, all institutions whose investment activities are
subject to legal investment laws and regulations, regulatory capital
requirements or review by regulatory authorities should consult with their legal
advisors in determining whether and to what extent any class of offered
certificates constitutes a legal investment or is subject to investment, capital
or other restrictions. On December 1, 1998, the Office of Thrift Supervision
issued Thrift Bulletin 13a, entitled "Management of Interest Rate Risk,
Investment Securities, and Derivatives Activities", which is applicable to
thrift institutions regulated by the OTS. TB 13a should be reviewed by any of
the above-mentioned thrift institutions prior to investing in the offered
certificates.

                              ERISA CONSIDERATIONS

         A fiduciary of any employee benefit plan or any other plan or
arrangement subject to the Employee Retirement Income Security Act of 1974, as
amended, or Section 4975 of the Code or any person investing Plan Assets of any
Plan should carefully review with its legal advisors whether the purchase, sale
or holding of Certificates will give rise to a prohibited transaction under
ERISA or Section 4975 of the Code.

         The U.S. Department of Labor has issued an individual exemption, as
described under "ERISA Considerations" in the prospectus, to the Underwriter.
The Exemption generally exempts from the application of some of the prohibited
transaction provisions of Section 406 of ERISA, and the excise taxes and civil
penalties imposed on these prohibited transactions by Section 4975(a) and (b) of
the Code and Section 502(i) of ERISA, transactions relating to the purchase,
sale and holding of pass-through certificates underwritten by the Underwriter,
such as the Offered Certificates, and the servicing and operation of asset pools
such as the mortgage pool, provided that certain conditions are satisfied. The
purchase of the offered certificates by, on behalf of or with the Plan Assets of
any Plan may qualify for exemptive relief under the Exemption. However, the
Exemption contains a number of conditions which must be met for the Exemption to
apply (as described in the prospectus), including the requirement that any Plan
must be an "accredited investor" as defined in Rule 501(a)(1) of Regulation D of
the Securities and Exchange Commission under the Securities Act of 1933, as
amended. A fiduciary of a Plan


                                      S-57


contemplating purchasing an Offered Certificate must make its own determination
that the conditions set forth in the Exemption will be satisfied with respect to
the Offered Certificates.

         Each beneficial owner of a Subordinate Certificate or any interest
therein must represent that either (i) it is not a Plan or investing with assets
of Plan, (ii) it has acquired and is holding such certificate in reliance on the
Exemption, and that it understands that there are certain conditions to the
availability of the Exemption, including that such certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by S&P, Fitch or
Moody's Investors Service, Inc., and such certificate is so rated or (iii) (1)
it is an insurance company, (2) the source of funds used to acquire or hold the
certificate or interest therein is an "insurance company general account," as
such term is defined in Prohibited Transaction Class Exemption ("PTCE") 95-60,
and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

         Before purchasing an Offered Certificate, a fiduciary of a Plan should
itself confirm (a) that the Offered Certificates constitute "certificates" for
purposes of the Exemption and (b) that the specific and general conditions of
the Exemption and the other requirements set forth in the Exemption would be
satisfied. Any Plan fiduciary that proposes to cause a Plan to purchase a
Certificate should consult with its counsel with respect to the potential
applicability to the investment of the fiduciary responsibility and prohibited
transaction provisions of ERISA and the Code to the proposed investment. For
further information regarding ERISA considerations of investing in the
Certificates, SEE "ERISA CONSIDERATIONS" IN THE PROSPECTUS.

REMOVAL AND SUBSTITUTION OF A MORTGAGE LOAN

The indenture trustee will acknowledge the sale, transfer and assignment of the
trust fund to it by the depositor and receipt of, subject to further review and
any exceptions, the mortgage loans. If the indenture trustee finds that any
mortgage loan is defective on its face due to a breach of the representations
and warranties with respect to that loan made in the transaction agreements, the
indenture trustee shall promptly notify the sponsor of such defect. The sponsor
must then correct or cure any such defect within 90 days from the date of notice
from the indenture trustee of the defect and if the sponsor fails to correct or
cure such defect within such period and such defect materially and adversely
affects the interests of the noteholders in the related mortgage loan, the
sponsor will, in accordance with the terms of the indenture, within 90 days of
the date of notice, provide the indenture trustee with a substitute


                                      S-6


mortgage loan (if within two years of the closing date); provided that, if such
defect would cause the mortgage loan to be other than a "qualified mortgage" as
defined in Section 860G(a)(3) of the Internal Revenue Code, any such cure or
substitution must occur within 90 days from the date such breach was discovered.

THE NOTES

OFFERED NOTES. The offered notes will have the characteristics shown in the
table above in this prospectus supplement. The interest rates on each class of
offered notes are variable and are calculated for each distribution date as
described in this prospectus supplement under "DESCRIPTION OF THE
NOTES--INTEREST RATES" in this prospectus supplement.

CREDIT ENHANCEMENT

The credit enhancement provided for the benefit of the holders of the offered
notes consists of subordination as described below and under "DESCRIPTION OF THE
NOTES--CREDIT ENHANCEMENT" "--ALLOCATION OF LOSSES; SUBORDINATION" and
overcollateralization as describeD below and under "DESCRIPTION OF THE
NOTES--OVERCOLLATERALIZATION PROVISIONS" in this prospectus supplement.

The rights of the holders of the subordinate notes and the equity certificates
to receive payments will be subordinated, to the extent described in this
prospectus supplement, to the rights of the holders of the Class A Notes. This
subordination is intended to enhance the likelihood of regular receipt by the
holders of the Class A Notes of the full amount of interest and principal to
which they are entitled and to afford those holders protection against realized
losses.

As of the closing date, the aggregate principal balance of the mortgage loans as
of the cut-off date will exceed the aggregate note balance of the notes by an
amount equal to approximately $_________. That amount represents approximately
____% of the aggregate principal balance of the mortgage loans as of the cut-off
date, which is the initial amount of overcollateralization required to be
provided by the mortgage pool under the indenture. Under the indenture, the
overcollateralized amount is required to be maintained at the required
overcollateralized amount.

 [Additional information with respect to credit enhancement providers, required
pursuant to Item 1114(b) of Regulation AB, will be provided if applicable.]

 [Any third parties providing credit support for 10% or more of the pool assets
will be identified].

[PRE-FUNDING ACCOUNTS]

[Additional information with respect to the pre-funding accounts, required
pursuant to Item 1103(a)(5) of Regulation AB, will be provided if applicable.]

ADVANCES

The master servicer will make cash advances with respect to delinquent payments
of scheduled interest and principal on the mortgage loans for which it acts as
master servicer, in general, to the extent that the master servicer reasonably
believes that such cash advances can be repaid from future payments on the
related mortgage loans. If the master servicer fails to make any required
advances, the indenture trustee may be obligated to do so, as described in this
prospectus supplement. These cash advances are only intended to maintain a

intended to guarantee or insure against losses.

SERVICING FEE

With respect to each mortgage loan, the amount of the annual master servicing
fee that shall be paid to the master servicer is for a period of one full month,
equal to one-twelfth of the product of (a) [___]% and (b) the stated principal
balance of the mortgage loan for the calendar month preceding the month in which
the payment is due. Such fee shall be payable monthly, computed on the basis of
the same principal amount and period on which any related interest payment on a
mortgage loan is computed. The obligation to pay the master servicing fee is
limited to, and the master servicing fee is payable from the interest portion of
such monthly payments collected.

OPTIONAL REDEMPTION

At its option, the majority holder of the equity certificates may redeem the
notes and thereby effect termination and early retirement of the notes, after
the aggregate Note balance has been reduced to less than [__%] of the aggregate
initial note balance.

                                  RISK FACTORS

         You should carefully consider, among other things, the following
factors in connection with the purchase of the offered notes:

[See version 1 of the prospectus supplement for some risk factors that may be
applicable.]

[Appropriate risk factors from the following list are particular to the
securitization represented by this version of the prospectus supplement]

[THE CLASS M-1, CLASS M-2 AND CLASS M-3 NOTES WILL BE PARTICULARLY SENSITIVE TO
LOSSES ON THE MORTGAGE LOANS

         The weighted average lives of, and the yields to maturity on, the Class
M-1, Class M-2 and Class M-3 Notes will be progressively more sensitive, in
increasing order of their numerical class designations, to the rate and timing
of mortgagor defaults and the severity of ensuing losses on the mortgage loans.
If the actual rate and severity of losses on the mortgage loans is higher than
those assumed by an investor in one of the Class M-1, Class M-2 or Class M-3
Notes, the actual yield to maturity of the note may be lower than the yield
anticipated by the holder based on the investor's assumption. The timing of
losses on the mortgage loans will also affect an investor's actual yield to
maturity, even if the rate of defaults and severity of losses over the life of
the mortgage pool are consistent with an investor's expectations. In general,
the earlier a loss occurs, the greater the effect on an investor's yield to
maturity. Losses on the mortgage loans in any due period, to the extent they
exceed the overcollateralized amount following payments of principal on the
related payment date, will reduce the note balance of the class of notes then
outstanding with the highest numerical class designation. As a result of these
reductions, less interest will accrue on the class of subordinate notes than
would otherwise be the case].

[THE CLASS M-1, CLASS M-2 AND CLASS M-3 NOTES WILL GENERALLY NOT BE ENTITLED TO
RECEIVE PRINCIPAL PAYMENTS UNTIL ALL PRINCIPAL PAYMENTS HAVE BEEN MADE ON THE
CLASS A NOTES WHICH MAY RESULT IN LOSSES ON THOSE NOTES

         Unless the note balance of the Class A Notes has been reduced to zero,
the Class M-1, Class M-2 and Class M-3 Notes will not be entitled to any
principal payments until _________ ____ or a later period as described in this
prospectus supplement. As a result, the weighted average lives of these notes
will be longer than would otherwise be the case if payments of principal were
allocated among all of the notes at the same time. As a result of the longer
weighted average lives of these notes, the holders of these notes have a greater
risk of suffering a loss on their investments. Further, because these notes
might not receive any principal if certain delinquency levels occur, it is
possible for these notes to receive no principal payments even if no losses have
occurred on the mortgage pool].

[THE NOTES ARE OBLIGATIONS OF THE TRUST ONLY

         The notes will not represent an interest in or obligation of the
originators, the depositor, the master servicer, the sponsor, _________, the
owner trustee, the indenture trustee or any of their respective affiliates. The
only obligations of the foregoing entities with respect to the notes or any
mortgage loan will be the obligations of the sponsor pursuant to the limited


                                      S-10


representations and warranties made with respect to the mortgage loans and of
the servicers with respect to their servicing obligations under the related
servicing agreement (including the limited obligation to make advances, as
described in this prospectus supplement). Neither the notes nor the underlying
mortgage loans will be guaranteed or insured by any governmental agency or
instrumentality, or by the issuing entity, the originators, the depositor, the
master servicer, the sponsor, ________, the owner trustee, the indenture trustee
or any of their respective affiliates. Proceeds of the assets included in the
trust (including the mortgage loans) will be the sole source of payments on the
notes, and there will be no recourse to the issuing entity, the originators, the
depositor, the master servicer, the sponsor, _______, the owner trustee, the
indenture trustee or any of their respective affiliates or any other entity in
the event that the proceeds are insufficient or otherwise unavailable to make
all payments provided for under the notes].

[THE DIFFERENCE BETWEEN THE INTEREST RATES ON THE NOTES AND THE MORTGAGE LOANS
MAY RESULT IN INTEREST SHORTFALLS ALLOCATED TO THE NOTES

         The note interest rate for each class of the notes adjusts monthly
based on a particular index, subject to the limitations described in this
prospectus supplement. However, the mortgage rates on the fixed rate mortgage
loans are fixed and will not vary with any index, and the mortgage rates on the
adjustable rate mortgage loans adjust semi-annually (after an initial fixed rate
period in the case of some of the adjustable rate mortgage loans) based on the
index (which may not move in tandem with the index), subject to periodic and
lifetime limitations as described in this prospectus supplement. As a result of
the foregoing as well as other factors like the prepayment behavior of the
mortgage pool, relative increases in the index or relative decreases in the
weighted average of the mortgage rates on the mortgage loans (i) could cause the
amount of interest generated by the mortgage pool to be less than the aggregate
of the amount of interest that would otherwise be payable on the notes, leading
one or more classes of notes to accept payments of interest at a later date, as
described in this prospectus supplement or (ii) could cause the maximum note
interest rate to apply to one or more classes of notes, as described in this
prospectus supplement.

         Because the mortgage rate for each adjustable rate mortgage loan will
be adjusted, subject to periodic and lifetime limitations, to equal the sum of
the index and the related gross margin, these rates could be higher than
prevailing market interest rates, possibly resulting in an increase in the rate
of prepayments on the adjustable rate mortgage loans after their adjustments. In
particular, investors should note that approximately _____% of the adjustable
rate mortgage loans have their interest rates fixed for two years following
origination and approximately _____% of the adjustable rate mortgage loans have
their interest rates fixed for three years following origination, in each case
by aggregate principal balance as of _________ __, ___. The weighted average
next adjustment date for the adjustable rate mortgage loans whose interest rates
are fixed for two years is _______ ____, and the weighted average next
adjustment date for the adjustable rate mortgage loans whose interest rates are
fixed for three years is _______ ____].


                                      S-11


[THE RATE AND TIMING OF PRINCIPAL DISTRIBUTIONS ON THE OFFERED NOTES WILL BE
AFFECTED BY PREPAYMENT SPEEDS

         The rate and timing of distributions allocable to principal on the
offered notes will depend, in general, on the rate and timing of principal
payments (including prepayments and collections upon defaults, liquidations and
repurchases) on the mortgage loans and the allocation thereof to pay principal
on the offered notes as provided in this prospectus supplement. As is the case
with mortgage securities generally, the offered notes are subject to substantial
inherent cash-flow uncertainties because the mortgage loans may be prepaid at
any time. However, with respect to approximately ____% of the mortgage loans, by
aggregate principal balance as of _______ __, ____, a prepayment may subject the
related mortgagor to a prepayment charge, which may act as a deterrent to
prepayment of the mortgage loan. SEE "THE MORTGAGE POOL" IN THIS PROSPECTUS
SUPPLEMENT.

         Generally, when prevailing interest rates are increasing, prepayment
rates on mortgage loans tend to decrease; a decrease in the prepayment rates on
the mortgage loans will result in a reduced rate of return of principal to
investors in the offered notes at a time when reinvestment at these higher
prevailing rates would be desirable. Conversely, when prevailing interest rates
are declining, prepayment rates on mortgage loans tend to increase; an increase
in the prepayment rates on the mortgage loans will result in a greater rate of
return of principal to investors in the offered notes at a time when
reinvestment at comparable yields may not be possible.

         Distributions of principal will be made to the subordinate notes
according to the priorities described in this prospectus supplement. The timing
of commencement of principal distributions and the weighted average life of each
of these classes of notes will be affected by the rates of prepayment on the
mortgage loans experienced both before and after the commencement of principal
distributions on the class. For further information regarding the effect of
principal prepayments on the weighted average lives of the offered notes, see
"YIELD ON THE NOTES" in this prospectus supplement and the table entitled
"PERCENT OF INITIAL NOTE BALANCE OUTSTANDING AT THE FOLLOWING PERCENTAGES OF THE
PREPAYMENT ASSUMPTION" therein.

[THE YIELD TO MATURITY ON THE OFFERED NOTES WILL DEPEND ON A VARIETY OF FACTORS

         The yield to maturity on the offered notes will depend, in general, on:

o        the applicable note interest rate and note accrual rate thereon from
         time to time;

o        the applicable purchase price; and

o        the rate and timing of principal payments (including prepayments and
         collections upon defaults, liquidations and repurchases) on the
         mortgage loans and the allocation thereof to reduce the note balance of
         the notes, as well as other factors.

         The yield to investors on any class of offered notes will be adversely
affected by any allocation thereto of interest shortfalls on the mortgage loans.

         In general, if the offered notes are purchased at a premium and
principal distributions thereon occur at a rate faster than anticipated at the
time of purchase, the investor's actual yield


                                      S-12


to maturity will be lower than that assumed at the time of purchase. Conversely,
if the offered notes are purchased at a discount and principal distributions
thereon occur at a rate slower than that anticipated at the time of purchase,
the investor's actual yield to maturity will be lower than that originally
assumed.

         The proceeds to the depositor from the sale of the offered notes were
determined based on a number of assumptions, including a prepayment assumption
of __% of the [constant prepayment rate model] and weighted average lives
corresponding thereto. No representation is made that the mortgage loans will
prepay at this particular rate or at any other rate. The yield assumptions for
the offered notes will vary as determined at the time of sale].

[THE SERVICING RIGHTS TO SOME OF THE MORTGAGE LOANS WILL BE TRANSFERRED TO THE
MASTER SERVICER WHICH MAY LEAD TO AN INCREASE IN DELINQUENCIES AND LOSSES ON
THOSE LOANS

         The master servicer and _____________ have advised the depositor that
with respect to a portion of the mortgage loans initially to be serviced by
___________, the servicing thereof is expected to be transferred to the master
servicer by _________ __, ____, whereupon the master servicer will act in the
capacity as "servicer" under the applicable servicing agreement to the extent of
those mortgage loans. The portion of the mortgage loans that are expected to be
subject to the servicing transfer represents approximately _____% of the
mortgage loans, by aggregate principal balance as of _________ __, ____.
Investors should note that when servicing of mortgage loans is transferred,
there may be a rise in delinquencies associated with the transfer].

FICO SCORES MENTIONED IN THIS PROSPECTUS SUPPLEMENT ARE NOT AN INDICATOR OF
FUTURE PERFORMANCE OF BORROWERS.

         Investors should be aware that FICO scores are based on past payment
history of the borrower. Investors should not rely on FICO scores as an
indicator of future borrower performance. See "The Mortgage Pools--FICO Scores"
in the base prospectus.

                                THE MORTGAGE POOL

GENERAL

         The mortgage pool will consist of approximately _____ conventional,
one- to four-family, fixed rate mortgage loans and approximately _____
conventional, one-to four-family, adjustable rate mortgage loans, in each case
secured by first liens on residential real properties and having an aggregate
principal balance as of Cut-off Date of approximately $___________ after
application of scheduled payments due on or before the Cut-off Date whether or
not received, subject to a permitted variance of plus or minus [5]%. The
mortgage loans have original terms to maturity of not greater than [30] years.
References to percentages of the mortgage loans, unless otherwise noted, are
calculated based on the aggregate principal balance of the mortgage loans as of
the Cut-off Date. The mortgage loans are secured by first mortgages or deeds of
trust or other similar security instruments creating first liens on residential
properties consisting of attached, detached or semi-detached, one- to
four-family dwelling units, townhouses, individual condominium units, individual
units in planned unit developments and manufactured housing.

         The mortgage loans to be included in the mortgage pool will be acquired
by the depositor on the Closing Date from ________________, who will have
acquired the mortgage loans on the Closing Date from the Sponsor. SEE
"--UNDERWRITING STANDARDS; REPRESENTATIONS" below and "THE SPONSOR" in this
prospectus supplement. The Sponsor in turn will have acquired the mortgage loans
on the Closing Date from [Name of Sponsor], an affiliate of the depositor. The
Sponsor will have acquired the mortgage loans directly or indirectly from the
Originators.

         Each adjustable rate mortgage loan provides for semi-annual adjustment
to the mortgage rate on that adjustable rate mortgage loan and for corresponding
adjustments to the monthly payment amount due on that adjustable rate mortgage
loan, in each case on each Adjustment Date applicable thereto; provided,
however, that in the case of approximately _____% and approximately _____% of
the adjustable rate mortgage loans by aggregate principal balance as of the
Cut-off Date, the first Adjustment Date will occur after an initial period of
approximately ____ years and approximately ______ years, respectively, from the
date of origination of that adjustable rate mortgage loan, each being a Delayed
First Adjustment Mortgage Loan. The weighted average month of origination of the
_____ year Delayed First Adjustment Mortgage Loans is _________ _____, and the
weighted average month of origination of the ______ year Delayed First
Adjustment Mortgage Loans is _________ _____. On each Adjustment Date, the
mortgage rate on each adjustable rate mortgage loan will be adjusted to equal
the sum, rounded as provided in the related mortgage note, of the Index (as
described below) and the Gross Margin; provided, however, that the mortgage rate
on each adjustable rate mortgage loan, including each Delayed First Adjustment
Mortgage Loan, will generally not increase or decrease by more than the Periodic
Rate Cap on any related Adjustment Date and will not exceed the Maximum Mortgage
Rate or be less than the Minimum Mortgage Rate. For Adjustment Dates other than
the first Adjustment Date after origination, the Periodic Rate Cap for the
majority of the adjustable rate mortgage loans is 1.00% per annum, and with
respect to substantially all of the adjustable rate mortgage loans, for
Adjustment Dates other than the first Adjustment Date after origination, the
Periodic Rate Cap will not exceed ____% per annum. Effective with the first
monthly payment due on each adjustable rate mortgage loan after each related
Adjustment


                                      S-14


Date, the monthly payment amount will be adjusted to an amount that will
amortize fully the outstanding principal balance of the related adjustable rate
mortgage loan over its remaining term and pay interest at the mortgage rate as
so adjusted. Due to the application of the Periodic Rate Caps and the Maximum
Mortgage Rates, the mortgage rate on each mortgage loan, as adjusted on any
related Adjustment Date, may be less than the sum of the Index and Gross Margin,
calculated as described in this prospectus supplement. SEE "--THE INDEX" IN THIS
PROSPECTUS SUPPLEMENT. None of the adjustable rate mortgage loans permits the
related mortgagor to convert the adjustable mortgage rate on that adjustable
rate mortgage loan to a fixed mortgage rate.

         The mortgage loans generally have scheduled monthly payments due on
each Due Date. Each mortgage loan will contain a customary "due-on-sale" clause
or will be assumable by a creditworthy purchaser of the related mortgaged
property.

         Approximately ______% of the mortgage loans provide for payment by the
mortgagor of a Prepayment Charge in limited circumstances on voluntary
prepayments in full made within one to five years from the date of origination
of those mortgage loans. The amount of the Prepayment Charge is as provided in
the related mortgage note. Prepayment Charge obligations generally expire by
their terms after a limited period specified in the related mortgage note. The
weighted average month of origination of the mortgage loans with Prepayment
Charges is _________ ____. The holders of the Equity Certificates will be
entitled to all Prepayment Charges received on the mortgage loans, and that
amount will [not] be available for distribution on the notes. Under some
instances, as described in the related Servicing Agreement, the related Servicer
may waive the payment of any otherwise applicable Prepayment Charge, and
accordingly, there can be no assurance that the Prepayment Charges will have any
effect on the prepayment performance of the mortgage loans.

         None of the mortgage loans are buydown mortgage loans.

         Approximately ____% of the mortgage loans are Balloon Loans. Each
Balloon Loan is a fixed rate mortgage loan that amortizes over ___ months, but
the Balloon Payment on each Balloon Loan is due and payable on the ___ month.
The amount of the Balloon Payment on each Balloon Loan is substantially in
excess of the amount of the scheduled monthly payment on that Balloon Loan for
the period prior to the Due Date of that Balloon Payment.

         The average principal balance of the mortgage loans at origination was
approximately $_______. No mortgage loan had a principal balance at origination
greater than approximately $________ or less than approximately $______. The
average principal balance of the mortgage loans as of the Cut-off Date was
approximately $_______.

         The mortgage loans had mortgage rates as of the Cut-off Date ranging
from approximately ____% per annum to approximately _____% per annum, and the
weighted average mortgage rate was approximately ______% per annum. The weighted
average loan-to-value ratio of the mortgage loans at origination was
approximately _____%. At origination, no mortgage loan will have a loan-to-value
ratio greater than approximately _____% or less than approximately ____%.


                                      S-15


         The weighted average remaining term to maturity of the mortgage loans
will be approximately __ years and __ months as of the Cut-off Date. None of the
mortgage loans will have a first Due Date prior to _______ ____ or after
___________ ____, or will have a remaining term to maturity of less than __
years or greater than __ years as of the Cut-off Date. The latest maturity date
of any mortgage loan is __________ ____.

         As of the Cut-off Date, the adjustable rate mortgage loans had Gross
Margins ranging from approximately ____% to approximately ____%, Minimum
Mortgage Rates ranging from approximately ____% per annum to approximately
_____% per annum and Maximum Mortgage Rates ranging from approximately _____%
per annum to approximately _____% per annum. As of the Cut-off Date, the
weighted average Gross Margin was approximately ______%, the weighted average
Minimum Mortgage Rate was approximately _____% per annum and the weighted
average Maximum Mortgage Rate was approximately _______% per annum. The latest
first Adjustment Date following the Cut-off Date on any adjustable rate mortgage
loan occurs in _______ ____ and the weighted average next Adjustment Date for
all of the mortgage loans following the Cut-off Date is _______ ____.

         [As of the Cut-off date, not more than [ ]% of the mortgage loans were
more than 30 days delinquent in payments of principal and interest. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
one time during the twelve months preceding the cut-off date. No more than
approximately [___]% of the mortgage loans have been 30 to 59 days delinquent
two times during the twelve months preceding the Cut-off date. No more than
approximately [___]% of the mortgage loans have been more than 60 days
delinquent one time during the twelve months preceding the cut-off date. No more
than approximately [___]% of the mortgage loans have been more than 60 days
delinquent two times during the twelve months preceding the cut-off date.] [No
mortgage loan will be more than 30 days delinquent as of the Cut-off Date.] A
loan is considered to be delinquent when a payment due on any due date remains
unpaid as of the close of business on the last business day immediately prior to
the next monthly due date. The determination as to whether a loan falls into
this category is made as of the close of business on the last business day of
each month.

         [If the trust contains mortgage securities, the mortgage securities
will be specifically identified by reference to the transaction(s) pursuant to
which such mortgage securities were issued, the percentage interest represented
by such mortgage securities and the characteristics of such mortgage securities
will be described in detail. In addition, the assets underlying the mortgage
securities will be described in detail.]

         The mortgage loans are expected to have the following characteristics
as of the Cut-off Date (the sum in any column may not equal the total indicated
due to rounding):

Residential Mortgage
Loans................



         Approximately [__]% of the mortgage loans have been originated
generally in accordance with credit, appraisal and underwriting standards
acceptable to [Name of Originator], which are referred to herein as the
Underwriting Standards. The Underwriting Standards are applied in accordance
with applicable federal and state laws and regulations.

THE INDEX

         As of any Adjustment Date, the Index applicable to the determination of
the mortgage rate on each mortgage loan will be the average of the interbank
offered rates for six-month United States dollar deposits in the London market
as published in THE WALL STREET JOURNAL and as of a date as specified in the
related mortgage note. In the event that the Index becomes unavailable or
otherwise unpublished, each Servicer will select a comparable alternative index
over which it has no direct control and which is readily verifiable.

         The table below sets forth historical average rates of six-month LIBOR
for the months indicated as made available from Fannie Mae, which rates may
differ from the rates of the Index, which is six-month LIBOR as published in THE
WALL STREET JOURNAL as described above. The table does not purport to be
representative of the subsequent rates of the Index which will be used to
determine the mortgage rate on each mortgage loan.

UNDERWRITING STANDARDS

         The mortgage loans will be acquired by the depositor on the Closing
Date from __________, who will have acquired the mortgage loans on the Closing
Date from the Sponsor. The Sponsor in turn will have acquired the mortgage loans
on the Closing Date from [Name of Sponsor]. [Name of Sponsor], an affiliate of
the depositor, will have acquired the mortgage loans directly or indirectly from
the Originators.

         The information presented below with regard to each Originator's
underwriting standards has been provided to the depositor or compiled from
information provided to the depositor by that Originator.


                                      S-24


         [Discussion of each Originator's Underwriting Standards used to
originate the mortgage loans follows. See version 1 of the prospectus
supplement].

REPRESENTATIONS AND WARRANTIES

         The Sponsor will make representations and warranties as of the Closing
Date with respect to the mortgage loans, and will be obligated to repurchase
that mortgage loan in respect of which a material breach of the representations
and warranties it has made has occurred (other than those breaches which have
been cured). For a discussion of the representations and warranties made and the
repurchase obligation, SEE "MORTGAGE LOAN PROGRAM--REPRESENTATIONS BY OR ON
BEHALF OF THE SPONSOR; REPURCHASES" IN THE PROSPECTUS.

         In the Mortgage Loan Purchase Agreement, pursuant to which the
Depositor purchased the mortgage loans from the Sponsor, the Sponsor made
certain representations and warranties to the Depositor concerning the mortgage
loans. The Indenture Trustee will be assigned all right, title and interest in
the Mortgage Loan Purchase Agreement insofar as they relate to such
representations and warranties made by the Sponsor.

         The representations and warranties of the Sponsor with respect to the
mortgage loans include the following, among others:

         (1) The information set forth in the mortgage loan schedule is true,
complete and correct in all material respects as of the Closing Date;

         (2) Immediately prior to the sale of the mortgage loans pursuant to the
Mortgage Loan Purchase Agreement, the Sponsor was the sole owner of beneficial
title and holder of each mortgage and mortgage note relating to the mortgage
loans and as of the Closing Date, or as of another specified date, is conveying
the same to the Depositor free and clear of any encumbrance, equity,
participation interest, lien, pledge, charge, mechanics' lien, assessment, claim
or security interest, and the Sponsor has full right and authority to sell and
assign each mortgage loan pursuant to the Mortgage Loan Purchase Agreement;

         (3) As of the Closing Date, the improvements on each Mortgaged Property
securing a Mortgage Loan are insured (by an insurer which is acceptable to the
Sponsor) against loss by fire, flood and such hazards as are covered under a
standard extended coverage endorsement in the locale in which the Mortgaged
Property is located, in an amount which is not less than the lesser of the
maximum insurable value of the improvements securing such Mortgage Loan or the
outstanding principal balance of the Mortgage Loan, but in no event in an amount
less than an amount that is required to prevent the Mortgagor from being deemed
to be a co-insurer thereunder;

         (4) Except to the extent insurance is in place which will cover such
damage, the physical property subject to any Mortgage is free of material damage
and is in good repair and there is no proceeding pending or threatened for the
total or partial condemnation of any Mortgaged Property;

         (5) The Mortgaged Property and all improvements thereon comply with all
requirements of any applicable zoning and subdivision laws and ordinances;


                                      S-25


         (6) A lender's title insurance policy (on an ALTA or CLTA form) or
binder, or other assurance of title customary in the relevant jurisdiction
therefor in a form acceptable to Fannie Mae or Freddie Mac, was issued on the
date that each Mortgage Loan was created by a title insurance company which, to
the best of the Sponsor's knowledge, was qualified to do business in the
jurisdiction where the related Mortgaged Property is located, insuring the
Sponsor and its successors and assigns that the Mortgage is a first priority
lien on the related Mortgaged Property in the original principal amount of the
Mortgage Loan. The Sponsor is the sole insured under such lender's title
insurance policy, and such policy, binder or assurance is valid and remains in
full force and effect, and each such policy, binder or assurance shall contain
all applicable endorsements including a negative amortization endorsement, if
applicable;

         (7) As of the Closing Date there is no material monetary default
existing under any Mortgage or the related Mortgage Note and there is no
material event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a default, breach or event of
acceleration; and neither the Sponsor nor any of its respective affiliates has
taken any action to waive any default, breach or event of acceleration; and no
foreclosure action is threatened or has been commenced with respect to the
Mortgage Loan;

         (8) Neither the Sponsor nor any prior holder of any Mortgage has
impaired, waived, altered or modified the Mortgage or Mortgage Notes in any
material respect (except that a Mortgage Loan may have been modified by a
written instrument which has been recorded, if necessary to protect the
interests of the owner of such Mortgage Loan or the Bonds, and which has been
delivered to the Indenture Trustee); satisfied, canceled or subordinated such
Mortgage in whole or in part; released the applicable Mortgaged Property in
whole or in part from the lien of such Mortgage; or executed any instrument of
release, cancellation or satisfaction with respect thereto; and

         (9) At the time of origination, if required, each Mortgaged Property
was the subject of an appraisal which conforms to the underwriting requirements
of the related originator; the Mortgage File contains an appraisal of the
applicable Mortgaged Property.

         In the case of a breach of any representation or warranty set forth
above which materially and adversely affects the value of the interests of
Bondholders or the Certificateholders, as applicable, or of the Depositor in any
of the mortgage loans, the Sponsor shall, within 90 days from the date of its
discovery or receipt of notice thereof, cure such breach or repurchase event in
all material respects or shall either (i) repurchase such Mortgage Loan from the
Issuing Entity at the repurchase price, or (ii) substitute one or more Eligible
Substitute Mortgage Loans for such Mortgage Loan, in each case in the manner and
subject to the conditions set forth in Mortgage Loan Purchase Agreement. The
obligations of the Sponsor to cure, repurchase or substitute shall constitute
the sole and exclusive remedy respecting a breach of such representations and
warranties available to the Depositor, the Issuing Entity, the
Certificateholders and the Bondholders against the sponsor.

ADDITIONAL INFORMATION

         The description in this prospectus supplement of the mortgage pool and
the mortgaged properties is based upon the mortgage pool as constituted as of
the close of business on the


                                      S-26


Cut-off Date, as adjusted for the scheduled principal payments due on or before
that date. Prior to the issuance of the notes, mortgage loans may be removed
from the mortgage pool as a result of incomplete documentation or otherwise if
the depositor deems that removal necessary or desirable, and may be prepaid at
any time. A limited number of other mortgage loans may be included in the
mortgage pool prior to the issuance of the notes unless including those mortgage
loans would materially alter the characteristics of the mortgage pool as
described in this prospectus supplement. The depositor believes that the
information provided in this prospectus supplement will be representative of the
characteristics of the mortgage pool as it will be constituted at the time the
notes are issued, although the range of mortgage rates and maturities and some
other characteristics of the mortgage loans may vary. In no event, however, will
more than 5% (by principal balance at the Cut-off Date) of the mortgage loans or
mortgage securities deviate from the characteristics of the mortgage loans or
mortgage securities set forth in the related prospectus supplement.

         If, as of the Closing Date, any material pool characteristic differs by
5% or more from the description in this prospectus supplement, revised
disclosure will be provided either in a supplement or in a current report on
Form 8-K.

                             STATIC POOL INFORMATION

         Static pool information material to this offering may be found at
__________________________. The Sponsor does not have any material static pool
information with respect to any mortgage loans of the same type as those
included in the trust fund originated by it prior to January 1, 2006, because
all or substantially all of these mortgage loans originated by the Sponsor prior
to that time were sold on a servicing released basis, and such information may
not be obtained without unreasonable effort or expense. With respect to any of
these mortgage loans originated by the Sponsor on or after January 1, 2006, the
static pool information provided does not include any information with respect
to any mortgage loan which was sold on a servicing released basis, except to the
extent the purchaser of that loan or another third-party has agreed to provide
that information back to the Sponsor and has actually provided it to the Sponsor
with indemnification.

         Information provided through the Internet address above will not be
deemed to be a part of this prospectus or the registration statement for the
securities offered hereby if it relates to any prior securities pool or vintage
formed before January 1, 2006, or with respect to the mortgage pool (if
applicable), any period before January 1, 2006.

                               YIELD ON THE NOTES

GENERAL PREPAYMENT CONSIDERATIONS

         The rate of principal payments on the notes, the aggregate amount of
payments on the notes and the yield to maturity of the notes will be related to
the rate and timing of payments of principal on the mortgage loans. The rate of
principal payments on the mortgage loans will in turn be affected by the
amortization schedules of those mortgage loans and by the rate of principal
prepayments on those mortgage loans (including for this purpose, payments
resulting from refinancings, liquidations of the mortgage loans due to defaults,
casualties, condemnations


                                      S-27


and repurchases, whether optional or required, by the depositor, the Sponsor or
the majority holder of the Equity Certificates, as the case may be). The
mortgage loans generally may be prepaid by the mortgagors at any time; however,
as described under "The Mortgage Pool" in this prospectus supplement, with
respect to approximately _____% of the mortgage loans, by aggregate principal
balance as of the Cut-off Date, a prepayment may subject the related mortgagor
to a Prepayment Charge. Prepayment Charge obligations generally expire by their
terms after a limited period specified in the related mortgage note. The
weighted average month of origination of the mortgage loans with Prepayment
Charges is ________ ____.

         Prepayments, liquidations and repurchases of the mortgage loans will
result in payments in respect of principal to the holders of the class or
classes of notes then entitled to receive those payments that otherwise would be
distributed over the remaining terms of the mortgage loans. SEE "MATURITY AND
PREPAYMENT CONSIDERATIONS" IN THE PROSPECTUS. Since the rates of payment of
principal on the mortgage loans will depend on future events and a variety of
factors (as described more fully in this prospectus supplement and in the
prospectus under "Yield Considerations" and "Maturity and Prepayment
Considerations"), no assurance can be given as to that rate or the rate of
principal prepayments. The extent to which the yield to maturity of any class of
notes may vary from the anticipated yield will depend upon the degree to which
those notes are purchased at a discount or premium and the degree to which the
timing of payments on those notes is sensitive to prepayments on the mortgage
loans. Further, an investor should consider, in the case of a Note purchased at
a discount, the risk that a slower than anticipated rate of principal payments
on the mortgage loans could result in an actual yield to that investor that is
lower than the anticipated yield and, in the case of a Note purchased at a
premium, the risk that a faster than anticipated rate of principal payments
could result in an actual yield to that investor that is lower than the
anticipated yield. In general, the earlier a prepayment of principal is made on
the mortgage loans, the greater the effect on the yield to maturity of the
notes. As a result, the effect on an investor's yield of principal payments
occurring at a rate higher (or lower) than the rate anticipated by the investor
during the period immediately following the issuance of those notes would not be
fully offset by a subsequent like reduction (or increase) in the rate of
principal payments.

         It is highly unlikely that the mortgage loans will prepay at any
constant rate until maturity or that all of the mortgage loans will prepay at
the same rate. Moreover, the timing of prepayments on the mortgage loans may
significantly affect the actual yield to maturity on the notes, even if the
average rate of principal payments experienced over time is consistent with an
investor's expectation.

         The rate of payments (including prepayments) on pools of mortgage loans
is influenced by a variety of economic, geographic, social and other factors. If
prevailing mortgage rates fall significantly below the mortgage rates on the
mortgage loans, the rate of prepayment (and refinancing) would be expected to
increase. Conversely, if prevailing mortgage rates rise significantly above the
mortgage rates on the mortgage loans, the rate of prepayment on the mortgage
loans would be expected to decrease. Other factors affecting prepayment of
mortgage loans include changes in mortgagors' housing needs, job transfers,
unemployment, mortgagors' net equity in the mortgaged properties and servicing
decisions. In addition, in the case of the adjustable rate mortgage loans in the
mortgage pool, the existence of the applicable Periodic Rate Cap, Maximum
Mortgage Rate and Minimum Mortgage Rate may affect the likelihood of


                                      S-28


prepayments resulting from refinancings. There can be no certainty as to the
rate of prepayments on the mortgage loans during any period or over the life of
the notes. SEE "YIELD CONSIDERATIONS" AND "MATURITY AND PREPAYMENT
CONSIDERATIONS" IN THE PROSPECTUS.

         Because principal payments are paid to some classes of notes before
other classes, holders of classes of notes having a later priority of payment
bear a greater risk of losses (because those notes will represent an increasing
percentage of the Trust Estate during the period prior to the commencement of
payments of principal on those notes) than holders of classes having earlier
priorities for payment of principal. As described under "Description of the
Notes--Principal Payments on the Notes" in this prospectus supplement, prior to
the Stepdown Date (as defined in this prospectus supplement), all principal
payments on the mortgage loans will be allocated to the Class A Notes.
Thereafter, as further described in this prospectus supplement, subject to
various delinquency triggers described in this prospectus supplement, all
principal payments on the mortgage loans will be allocated among all classes of
the notes then outstanding as described under "Description of the
Notes--Principal Payments on the Notes" in this prospectus supplement.

         In general, defaults on mortgage loans are expected to occur with
greater frequency in their early years. In addition, default rates may be higher
for mortgage loans used to refinance an existing mortgage loan. In the event of
a mortgagor's default on a mortgage loan, there can be no assurance that
recourse will be available beyond the specific mortgaged property pledged as
security for repayment. SEE "THE MORTGAGE POOL--UNDERWRITING STANDARDS;
REPRESENTATIONS" IN THIS PROSPECTUS SUPPLEMENT.

SPECIAL YIELD CONSIDERATIONS

         The Note Interest Rate for each class of the notes adjusts monthly
based on One-Month LIBOR as described under "DESCRIPTION OF THE
NOTES--CALCULATION OF ONE-MONTH LIBOR" in this prospectus supplement, subject to
the Maximum Note Interest Rate and the Available Interest Rate. However, the
mortgage rates on the fixed rate mortgage loans are fixed and will not vary with
any index, and the mortgage rates on the adjustable rate mortgage loans adjust
semi-annually (after an initial fixed rate period in the case of Delayed First
Adjustment Mortgage Loans) based on the Index (which may not move in tandem with
One- Month LIBOR), subject to periodic and lifetime limitations as described in
this prospectus supplement. Investors should note that approximately _____% of
the mortgage loans are ____ year Delayed First Adjustment Mortgage Loans,
approximately ____% of the mortgage loans are _____ year Delayed First
Adjustment Loans and approximately _____% of the mortgage loans are fixed rate
mortgage loans, in each case by aggregate principal balance as of the Cut-off
Date. The weighted average month of origination of the two year Delayed First
Adjustment Mortgage Loans is _____ ____, and the weighted average month of
origination of the ______ year Delayed First Adjustment Mortgage Loans is ______
____. Because of the application of the Maximum Note Interest Rate and the
Available Interest Rate, increases in the Note Interest Rate on the notes may be
limited for extended periods or indefinitely in a rising interest rate
environment. The interest due on the mortgage loans during any Due Period may
not equal the amount of interest that would accrue at One-Month LIBOR plus the
applicable spread on the notes during the related Interest Accrual Period. In
addition, the Index and One-Month LIBOR may respond differently to economic and
market factors. Thus, it is possible, for example, that if both One-Month LIBOR
and the Index


                                      S-29


rise during the same period, One-Month LIBOR may rise more rapidly than the
Index or may rise higher than the Index, potentially resulting in Interest Carry
Forward Amounts with respect to one or more classes of notes. As a result of the
foregoing as well as other factors such as the prepayment behavior of the
mortgage pool, relative increases in One-Month LIBOR or relative decreases in
the weighted average of the mortgage rates on the mortgage loans (i) could cause
the Current Interest Payment Amount generated by the mortgage pool to be less
than the aggregate of the Interest Payment Amounts that would otherwise be
payable on the notes, leading one or more classes of notes to incur Interest
Carry Forward Amounts, or (ii) could cause the Maximum Note Interest Rate to
apply to one or more classes of notes.

         Because the mortgage rate for each adjustable rate mortgage loan will
be adjusted, subject to periodic and lifetime limitations, to equal the sum of
the Index and the related Gross Margin, those rates could be higher than
prevailing market interest rates, possibly resulting in an increase in the rate
of prepayments on the adjustable rate mortgage loans after their adjustments.

         As described under "Description of the Notes--Allocation of Losses;
Subordination", amounts otherwise distributable to holders of the Subordinate
Notes may be made available to protect the holders of the Class A Notes against
interruptions in payments due to various mortgagor delinquencies, to the extent
not covered by P&I Advances. Those delinquencies may affect the yield to
investors on those classes of Subordinate Notes and, even if subsequently cured,
will affect the timing of the receipt of payments by the holders of those
classes of Subordinate Notes. In addition, a larger than expected rate of
delinquencies or losses will affect the rate of principal payments on each class
of Subordinate Notes. SEE "DESCRIPTION OF THE NOTES--PRINCIPAL PAYMENTS ON THE
NOTES" IN THIS PROSPECTUS SUPPLEMENT.

WEIGHTED AVERAGE LIVES

         Weighted average life refers to the amount of time that will elapse
from the date of issuance of a security until each dollar of principal of that
security will be repaid to the investor. The weighted average life of each class
of notes will be influenced by the rate at which principal on the mortgage loans
is paid, which may be in the form of scheduled payments or prepayments
(including repurchases and prepayments of principal by the borrower as well as
amounts received by virtue of condemnation, insurance or foreclosure with
respect to the mortgage loans), and the timing of those principal payments.

         Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. The Prepayment Assumption assumes a prepayment
rate for the mortgage loans of __% CPR. The CPR assumes that the outstanding
principal balance of a pool of mortgage loans prepays at a specified constant
annual rate or CPR. In generating monthly cash flows, this rate is converted to
an equivalent constant monthly rate. To assume __% CPR or any other CPR
percentage is to assume that the stated percentage of the outstanding principal
balance of the pool is prepaid over the course of a year. No representation is
made that the mortgage loans will prepay at __% CPR or any other rate.

         The tables following the next paragraph indicate the percentage of the
initial Note Balance of the notes that would be outstanding after each of the
dates shown at various percentages of the Prepayment Assumption and the
corresponding weighted average lives of


                                      S-30


those notes. The tables are based on the following modeling assumptions (the
"Structuring Assumptions"): (i) the mortgage pool consists of __ mortgage loans
with the characteristics described below, (ii) payments on those notes are
received, in cash, on the 25th day of each month, commencing in _______ ____,
(iii) the mortgage loans prepay at the percentages of the Prepayment Assumption
indicated, (iv) no defaults or delinquencies occur in the payment by mortgagors
of principal and interest on the mortgage loans, (v) none of the majority holder
of the Equity Certificates, the Sponsor, the Master Servicer, the Servicers or
any other person purchases from the Trust Estate any mortgage loan or redeems
the notes pursuant to any obligation or option under the Indenture, the
Servicing Agreements or any other agreement except as indicated in footnote two
in the tables below, and no partial early redemption of the notes occurs with
respect to the ___________ Mortgage Loans, (vi) scheduled monthly payments on
the mortgage loans are received on the first day of each month commencing in
_______ ____, and are computed prior to giving effect to any prepayments
received in the prior month, (vii) prepayments representing payment in full of
individual mortgage loans are received on the last day of each month commencing
in ________ ____, and include 30 days' interest on those mortgage loans, (viii)
the scheduled monthly payment for each mortgage loan is calculated based on its
principal balance, mortgage rate, original term to stated maturity and remaining
term to stated maturity so that the mortgage loan will amortize in amounts
sufficient to repay the remaining principal balance of that mortgage loan by its
remaining term to stated maturity, (ix) the notes are purchased on ________ __,
____, (x) the Index remains constant at _____% per annum and the mortgage rate
on each adjustable rate mortgage loan is adjusted on the next Adjustment Date
(and on subsequent Adjustment Dates, if necessary) to equal the Index plus the
applicable Gross Margin, subject to the applicable Periodic Rate Cap, (xi)
One-Month LIBOR remains constant at _____% per annum, (xii) the monthly payment
on each adjustable rate mortgage loan is adjusted on the Due Date immediately
following the next Adjustment Date (and on subsequent Adjustment Dates, if
necessary) to equal a fully amortizing monthly payment as described in clause
(viii) above and (xiii) the Master Servicing Fee Rate is as shown in the
"Assumed Mortgage Loan Characteristics" table below and the Master Servicing Fee
is payable monthly, the Servicing Fee Rate for each Servicer is equal to ____%
per annum and the Servicing Fees are payable monthly, and the Indenture Trustee
Fee Rate is equal to ______% per annum and the Indenture Trustee Fee is paid
monthly.

         There will be discrepancies between the characteristics of the actual
mortgage loans and the characteristics assumed in preparing the tables. This
discrepancy may have an effect upon the percentages of the initial Note Balance
outstanding (and the weighted average lives) of the notes shown in the tables.
In addition, since the actual mortgage loans included in the mortgage pool will
have characteristics that differ from those assumed in preparing the tables
shown below and since it is not likely the level of the Index or One-Month LIBOR
will remain constant as assumed, the notes may mature earlier or later than
indicated by the tables. In addition, as described under "Description of the
Notes--Principal Payments on the Notes" in this prospectus supplement, the
occurrence of the Stepdown Date or a Trigger Event (each as defined in this
prospectus supplement) will have the effect of accelerating or decelerating the
amortization of


                                      S-31


the notes, affecting the weighted average lives of the notes. Based on the
foregoing Structuring Assumptions, the tables indicate the weighted average
lives of the notes and show the percentages of the initial Note Balance of those
notes that would be outstanding after each of the Payment Dates shown, at
various percentages of the Prepayment Assumption. Neither the prepayment model
used in this prospectus supplement nor any other prepayment model or assumption
purports to be a historical description of prepayment experience or a prediction
of the anticipated rate of prepayment of any pool of mortgage loans, including
the mortgage loans included in the mortgage pool. Variations in the prepayment
experience and the balance of the mortgage loans that prepay may increase or
decrease the percentages of initial Note Balances (and weighted average lives)
shown in the following tables. Those variations may occur even if the average
prepayment experience of all the mortgage loans equals any of the specified
percentages of the Prepayment Assumption.

(1)      The weighted average life of a Note is determined by (a) multiplying
         the amount of each payment of principal by the number of years from the
         date of issuance of the Note to the related Payment Date, (b) adding
         the results and (c) dividing the sum by the initial Note Balance of the
         notes.

(2)      Calculated pursuant to footnote one but assumes the majority holder of
         the Equity Certificates exercises its option to redeem the notes when
         the aggregate Note Balance has been reduced to less than 20% of the
         initial aggregate Note Balance. SEE "THE INDENTURE AND OWNER TRUST
         AGREEMENT--REDEMPTION" IN THIS PROSPECTUS SUPPLEMENT.


         There is no assurance that prepayments of the mortgage loans will
conform to any of the levels of the Prepayment Assumption indicated in the
tables above, or to any other level, or that the actual weighted average lives
of the notes will conform to any of the weighted average lives shown in the
tables above. Furthermore, the information contained in the tables with respect
to the weighted average lives of the notes is not necessarily indicative of the
weighted average lives that might be calculated or projected under different or
varying prepayment or Index level assumptions.

         The characteristics of the mortgage loans will differ from those
assumed in preparing the tables above. In addition, it is unlikely that any
mortgage loan will prepay at any constant percentage until maturity, that all of
the mortgage loans will prepay at the same rate or that the level of the Index
will remain constant or at any level for any period of time. The timing of
changes in the rate of prepayments may significantly affect the actual yield to
maturity to investors, even if the average rate of principal prepayments and the
level of the Index is consistent with the expectations of investors.

YIELD SENSITIVITY OF THE SUBORDINATE NOTES

         If on any Payment Date, the Overcollateralized Amount and the Note
Balances of the Class M-3 Notes and the Class M-2 Notes have been reduced to
zero, the yield to maturity on the Class M-1 Notes will become extremely
sensitive to losses on the mortgage loans (and the timing of those losses) that
are covered by subordination, because the entire amount of any Realized Losses
(to the extent not covered by Net Monthly Excess Cashflow) will be allocated to
the Class M-1 Notes. If on any Payment Date, the Overcollateralized Amount and
the Note Balance of the Class M-3 Notes have been reduced to zero, the yield to
maturity on the Class M-2 Notes will become extremely sensitive to losses on the
mortgage loans (and the timing of those losses) that are covered by
subordination, because the entire amount of any Realized Losses (to the extent
not covered by Net Monthly Excess Cashflow) will be allocated to the Class M-2
Notes. If on any Payment Date, the Overcollateralized Amount has been reduced to
zero, the yield to maturity on the Class M-3 Notes will become extremely
sensitive to losses on


                                      S-33


the mortgage loans (and the timing of those losses) that are covered by
subordination, because the entire amount of any Realized Losses (to the extent
not covered by Net Monthly Excess Cashflow) will be allocated to the Class M-3
Notes. Once Realized Losses have been allocated to the Subordinate Notes, those
Realized Losses will not be reinstated thereafter. However, Allocated Realized
Loss Amounts may be paid to the holders of those classes of notes, after various
distributions to the holders of the Class A Notes and Subordinate Notes with
lower numerical class designations, but before the Equity Certificates are
entitled to any distributions. SEE "DESCRIPTION OF THE
NOTES--OVERCOLLATERALIZATION PROVISIONS" IN THIS PROSPECTUS SUPPLEMENT.

         Investors in the Subordinate Notes should fully consider the risk that
Realized Losses on the mortgage loans could result in the failure of those
investors to fully recover their investments. For additional considerations
relating to the yield on the Subordinate Notes, SEE "YIELD CONSIDERATIONS" AND
"MATURITY AND PREPAYMENT CONSIDERATIONS" IN THE PROSPECTUS.

                            DESCRIPTION OF THE NOTES

GENERAL

         Impac MBN Trust Series ____-__, Mortgage-Backed Notes, Series ____-__
will consist of ____ classes of notes, designated as (i) the Class A Notes and
(ii) the Class M-1 Notes, the Class M-2 Notes and the Class M-3 Notes. The notes
will be issued by Impac MBN Trust Series ____-__ pursuant to the Indenture,
dated as of ________ __, ____, between the Issuing Entity and the Indenture
Trustee. Only the notes are offered by this prospectus supplement. Trust
Certificates, Series ____-__ will be issued pursuant to the Owner Trust
Agreement, dated as of ________ __, ____, between the depositor and the Owner
Trustee, and will represent the beneficial ownership interest in the Issuing
Entity. The Equity Certificates are not being offered by this prospectus
supplement and will be delivered on the Closing Date to the ____________, as
partial consideration for the conveyance of the mortgage loans by ____________
to the depositor.

         Distributions on the offered notes will be made on each Distribution
Date.

         The notes represent non-recourse debt obligations of the Issuing Entity
secured by the Trust Estate, which consists primarily of a mortgage pool of
conventional, one- to four-family, adjustable rate mortgage loans and fixed rate
mortgage loans having an aggregate principal balance as of the Cut-off Date of
approximately $___________, subject to a permitted variance as described in this
prospectus supplement under "The Mortgage Pool". Proceeds of the Trust Estate
will be the sole source of payments on the notes. The Issuing Entity is not
expected to have any significant assets other than the Trust Estate pledged as
collateral to secure the notes.

         The Class A Notes, the Class M-1 Notes, the Class M-2 Notes and the
Class M-3 Notes will have an aggregate initial Note Balance of approximately
$___________, approximately $_________, approximately $__________ and
approximately $__________, respectively, in each case subject to a permitted
variance of plus or minus [5]%. The Note Interest Rates on the notes are
adjustable, subject to the Maximum Note Interest Rate and the Available Interest
Rate, and will be calculated for each Payment Date as described under "--Note
Interest Rate" in this


                                      S-34


prospectus supplement. The "Final Maturity Date" of the notes is the Payment
Date occurring in _________ _____.

         The notes will be issued, maintained and transferred on the book-entry
records of DTC and its participants in minimum denominations of $[10,000] and
integral multiples of $[1.00] in excess of that minimum denomination.

         The notes will initially be represented by one or more global notes
registered in the name of the nominee of DTC, except as provided below. The
depositor has been informed by DTC that DTC's nominee will be CEDE. No person
acquiring an interest in any class of the notes will be entitled to receive a
note representing those person's interest, except as described below under
"--Definitive Notes". Unless and until Definitive Notes are issued under the
limited circumstances described in this prospectus supplement, all references to
actions by noteholders with respect to the notes shall refer to actions taken by
DTC upon instructions from its participants (as defined below), and all
references in this prospectus supplement to payments, notices, reports and
statements to noteholders with respect to the notes shall refer to payments,
notices, reports and statements to DTC or CEDE, as the registered holder of the
notes, for payment to Note Owners in accordance with DTC procedures. SEE
"--REGISTRATION" AND "--DEFINITIVE NOTES" IN THIS PROSPECTUS SUPPLEMENT.

         Any Definitive Notes will be transferable and exchangeable at the
offices of the Indenture Trustee. No service charge will be imposed for any
registration of transfer or exchange, but the Indenture Trustee may require
payment of a sum sufficient to cover any tax or other governmental charge
imposed in connection therewith.

         All payments to holders of the notes, other than the final payment on
any class of notes, will be made by or on behalf of the Indenture Trustee to the
persons in whose names those notes are registered at the close of business on
each Record Date. Those payments will be made either (a) by check mailed to the
address of that noteholder as it appears in the Note Register or (b) upon
written request to the Indenture Trustee at least five business days prior to
the relevant Record Date by any holder of notes having an aggregate initial Note
Balance that is in excess of the lesser of (i) $5,000,000 or (ii) two-thirds of
the initial aggregate Note Balance of that class of notes, by wire transfer in
immediately available funds to the account of that noteholder specified in the
request. The final payment on any class of notes will be made in like manner,
but only upon presentment and surrender of those notes at the corporate trust
office of the Indenture Trustee or another location specified in the notice to
noteholders of that final payment.

REGISTRATION

         DTC is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. DTC was created to hold securities
for its participants and to facilitate the clearance and settlement of
securities transactions between participants through electronic book entries,
thereby eliminating the need for physical movement of notes. participants
include securities brokers and dealers


                                      S-35


(including [Name of Underwriter]), banks, trust companies and clearing
corporations. Indirect access to the DTC system is also available to indirect
participants.

         Note Owners that are not participants or indirect participants but
desire to purchase, sell or otherwise transfer ownership of, or other interests
in, the notes may do so only through participants and indirect participants. In
addition, Note Owners will receive all payments of principal of and interest on
the notes from the Indenture Trustee through DTC and DTC participants. The
Indenture Trustee will forward payments to DTC in same day funds and DTC will
forward those payments to participants in next day funds settled through the New
York Clearing House. Each Participant will be responsible for disbursing those
payments to indirect participants or to Note Owners. Unless and until Definitive
Notes are issued, it is anticipated that the only holder of the notes will be
CEDE, as nominee of DTC. Note Owners will not be recognized by the Indenture
Trustee as noteholders, as that term is used in the Indenture, and Note Owners
will be permitted to exercise the rights of noteholders only indirectly through
DTC and its participants.

         Under the rules, regulations and procedures creating and affecting DTC
and its operations, DTC is required to make book-entry transfers of notes among
participants and to receive and transmit payments of principal of, and interest
on, the notes. Participants and indirect participants with which Note Owners
have accounts with respect to the notes similarly are required to make
book-entry transfers and receive and transmit those payments on behalf of their
respective Note Owners. Accordingly, although Note Owners will not possess
Definitive Notes, the Rules provide a mechanism by which Note Owners through
their participants and indirect participants will receive payments and will be
able to transfer their interest.

         Because DTC can only act on behalf of participants, who in turn act on
behalf of indirect participants and on behalf of some banks, the ability of a
Note Owner to pledge notes to persons or entities that do not participate in the
DTC system, or to otherwise act with respect to those notes, may be limited due
to the absence of physical notes for the notes. In addition, under a book-entry
format, Note Owners may experience delays in their receipt of payments since
payment will be made by the Indenture Trustee to CEDE, as nominee for DTC.

         Under the Rules, DTC will take action permitted to be taken by a
noteholder under the Indenture only at the direction of one or more participants
to whose DTC account the notes are credited. Clearstream or the Euroclear
Operator (as defined in this prospectus supplement), as the case may be, will
take any other action permitted to be taken by a noteholder under the Indenture
on behalf of a Clearstream Participant (as defined in this prospectus
supplement) or Euroclear Participant (as defined in this prospectus supplement)
only in accordance with its relevant rules and procedures and subject to the
ability of the Relevant Depositary (as defined in this prospectus supplement) to
effect those actions on its behalf through DTC. Additionally, under the Rules,
DTC will take those actions with respect to specified Voting Rights only at the
direction of and on behalf of participants whose holdings of notes evidence
those specified Voting Rights. DTC may take conflicting actions with respect to
Voting Rights to the extent that participants whose holdings of notes evidence
those Voting Rights, authorize divergent action.

         The Issuing Entity, the Originators, the depositor, the Master
Servicer, the Sponsor, ________, the Owner Trustee, the Indenture Trustee and
their respective affiliates will have no


                                      S-36


liability for any actions taken by DTC or its nominee or Clearstream or
Euroclear, including actions for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the notes held by
CEDE, as nominee for DTC, or for maintaining, supervising or reviewing any
records relating to those beneficial ownership interests.

DEFINITIVE NOTES

         Definitive Notes will be issued to Note Owners or their nominees,
rather than to DTC or its nominee, only if (i) the depositor advises the
Indenture Trustee in writing that DTC is no longer willing or able to discharge
properly its responsibilities as clearing agency with respect to the notes and
the depositor is unable to locate a qualified successor, (ii) the depositor, at
its option, advises the Indenture Trustee in writing that it elects to terminate
the book-entry system through DTC, or (iii) after the occurrence of an Event of
Default (as defined in this prospectus supplement), Note Owners representing in
the aggregate not less than 51% of the Voting Rights of the notes advise the
Indenture Trustee and DTC through participants, in writing, that the
continuation of a book-entry system through DTC (or a successor thereto) is no
longer in the Note Owners' best interest.

         Upon the occurrence of any event described in the immediately preceding
paragraph, the Indenture Trustee is required to notify all Note Owners through
participants of the availability of Definitive Notes. Upon surrender by DTC of
the definitive notes representing the Notes and receipt of instructions for re-
registration, the Indenture Trustee will reissue the notes as Definitive Notes
issued in the respective principal amounts owned by individual Note Owners, and
thereafter the Indenture Trustee will recognize the holders of those Definitive
Notes as noteholders under the Indenture. Those Definitive Notes will be issued
in minimum denominations of $10,000, except that any beneficial ownership
represented by a note in an amount less than $10,000 immediately prior to the
issuance of a Definitive Note shall be issued in a minimum denomination equal to
the amount represented by that note.

BOOK-ENTRY FACILITIES

         Note Owners may elect to hold their interests in the notes through DTC
in the United States or through Clearstream or Euroclear in Europe, if they are
participants of those systems, or indirectly through organizations which are
participants in those systems. The notes of each class will be issued in one or
more notes which equal the aggregate Note Balance of that class and will
initially be registered in the name of Cede, the nominee of DTC. Clearstream and
Euroclear will hold omnibus positions on behalf of their participants through
customers' securities accounts in Clearstream's and Euroclear's names on the
books of their respective depositaries which in turn will hold those positions
in customers' securities accounts in the depositaries' names on the books of
DTC. Citibank will act as depositary for Clearstream and Chase will act as
depositary for Euroclear.

         Because of time zone differences, credits of securities received in
Clearstream or Euroclear as a result of a transaction with a Participant will be
made during subsequent securities settlement processing and dated the business
day following the DTC settlement date. Those credits or any transactions in
those securities settled during that processing will be reported to the relevant
Euroclear participants or Clearstream participants on that business day. Cash
received in


                                      S-37


Clearstream or Euroclear as a result of sales of securities by or through a
Clearstream Participant or Euroclear Participant to a Participant will be
received with value on the DTC settlement date but will be available in the
relevant Clearstream or Euroclear cash account only as of the business day
following settlement in DTC.

         Transfers between participants will occur in accordance with DTC rules.
Transfers between Clearstream participants and Euroclear participants will occur
in accordance with their respective rules and operating procedures.

         Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Clearstream
participants or Euroclear participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, those cross market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in that system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. Clearstream participants and Euroclear participants may not deliver
instructions directly to the European Depositaries.

         Clearstream is incorporated under the laws of Luxembourg as a
professional depository. Clearstream holds securities for its Clearstream
participants and facilitates the clearance and settlement of securities
transactions between Clearstream participants through electronic book-entry
changes in accounts of Clearstream participants, thereby eliminating the need
for physical movement of notes. Transactions may be settled in Clearstream in
any of 28 currencies, including United States dollars. Clearstream provides to
its Clearstream participants, among other things, services for safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. Clearstream interfaces with domestic
markets in several countries. As a professional depository, Clearstream is
subject to regulation by the Luxembourg Monetary Institute. Clearstream
participants are recognized financial institutions around the world, including
underwriters, securities brokers and dealers, banks, trust companies, clearing
corporations and other organizations. Indirect access to Clearstream is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Clearstream
Participant, either directly or indirectly.

         Euroclear was created in 1968 to hold securities for its Euroclear
participants and to clear and settle transactions between Euroclear participants
through simultaneous electronic book-entry delivery against payment, thereby
eliminating the need for physical movement of notes and any risk from lack of
simultaneous transfers of securities and cash. Transactions may now be settled
in any of 32 currencies, including United States dollars. Euroclear includes
various other services, including securities lending and borrowing and
interfaces with domestic markets in several countries generally similar to the
arrangements for cross-market transfers with DTC described above. Euroclear is
operated by the Brussels, Belgium office of the Euroclear Operator, under
contract with the Cooperative. All operations are conducted by the Euroclear
Operator, and all Euroclear securities clearance accounts and Euroclear cash
accounts are


                                      S-38


accounts with the Euroclear Operator, not the Cooperative. The Cooperative
establishes policy for Euroclear on behalf of Euroclear participants. Euroclear
participants include banks (including central banks), securities brokers and
dealers and other professional financial intermediaries. Indirect access to
Euroclear is also available to other firms that clear through or maintain a
custodial relationship with a Euroclear Participant, either directly or
indirectly.

         The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.

         Securities clearance accounts and cash accounts with the Euroclear
Operator are governed by the Terms and Conditions Governing Use of Euroclear and
the related Operating Procedures of the Euroclear System and applicable Belgian
law. The Terms and Conditions govern transfers of securities and cash within
Euroclear, withdrawals of securities and cash from Euroclear, and receipts of
payments with respect to securities in Euroclear. All securities in Euroclear
are held on a fungible basis without attribution of specific notes to specific
securities clearance accounts. The Euroclear Operator acts under the Terms and
Conditions only on behalf of Euroclear participants, and has no record of or
relationship with persons holding through Euroclear participants.

         Payments with respect to notes held through Clearstream or Euroclear
will be credited to the cash accounts of Clearstream participants or Euroclear
participants in accordance with the relevant system's rules and procedures, to
the extent received by the Relevant Depositary. Those payments will be subject
to tax reporting in accordance with relevant United States tax laws and
regulations.

         Although DTC, Clearstream and Euroclear have agreed to the foregoing
procedures in order to facilitate transfers of notes among participants of DTC,
Clearstream and Euroclear, they are under no obligation to perform or continue
to perform those procedures and those procedures may be discontinued at any
time. SEE "DESCRIPTION OF THE SECURITIES--FORM OF SECURITIES" IN THE PROSPECTUS.

NOTE INTEREST RATES

         The Note Interest Rate on the Class A Notes will be a rate per annum
equal to the lesser of (i) One- Month LIBOR plus ____%, in the case of each

Payment Date thereafter, (ii) the Available Interest Rate for that Payment Date
and (iii) the Maximum Note Interest Rate.

         The Note Interest Rate on the Class M-3 Notes will be a rate per annum
equal to the lesser of (i) One- Month LIBOR plus ____%, in the case of each

the Available Interest Rate for that Payment Date and (iii) the Maximum Note
Interest Rate.

         SEE "--CALCULATION OF ONE-MONTH LIBOR" IN THIS PROSPECTUS SUPPLEMENT.

         The Note Interest Rate and the Note Accrual Rate for the notes for the
current related Interest Accrual Period, to the extent it has been determined,
and for the immediately preceding Interest Accrual Period may be obtained by
telephoning the Indenture Trustee at __________.

INTEREST PAYMENTS ON THE NOTES

         To the extent of the Current Interest Payment Amount, in the priorities
listed below, the holders of each class of notes will be entitled to receive on
each Payment Date interest payments in an amount equal to the Interest Payment
Amount for that class. On each Payment Date, the Current Interest Payment Amount
will be distributed in the following order of priority:

         FIRST, to the holders of the Class A Notes, the Interest Payment Amount
         for those notes;

         SECOND, to the extent of the Current Interest Payment Amount remaining
         after payment of the Interest Payment Amount for the Class A Notes, to
         the holders of the Class M-1 Notes, the Interest Payment Amount for
         those Notes;

         THIRD, to the extent of the Current Interest Payment Amount remaining
         after payment of the Interest Payment Amounts for the Class A Notes and
         the Class M-1 Notes, to the holders of the Class M-2 Notes, the
         Interest Payment Amount for those notes; and

         FOURTH, to the extent of the Current Interest Payment Amount remaining
         after payment of the Interest Payment Amounts for the Class A Notes,
         the Class M-1 Notes and the Class M-2 Notes, to the holders of the
         Class M-3 Notes, the Interest Payment Amount for those notes.

         With respect to any Payment Date, to the extent that the aggregate of
the Interest Payment Amounts for the notes is limited by the Current Interest
Payment Amount for the related Due Period, the holders of some classes of notes
may receive an Interest Payment


                                      S-40


Amount calculated at the Available Interest Rate rather than at the applicable
Note Accrual Rate for those classes and that Payment Date. The Interest Carry
Forward Amount, if any, for any class of the notes for any Payment Date is
payable to the extent of available funds remaining after some other payments on
the notes on that Payment Date, but before any payments on the Equity
Certificates on that Payment Date. SEE "--OVERCOLLATERALIZATION PROVISIONS" IN
THIS PROSPECTUS SUPPLEMENT.

         All payments of interest on the notes will be based on a 360-day year
and the actual number of days in the applicable Interest Accrual Period.

         The Note Balance of a note outstanding at any time represents the then
maximum amount that the holder of that note is entitled to receive as payments
allocable to principal from the cash flow on the mortgage loans and the other
assets in the Trust Estate.

CALCULATION OF ONE-MONTH LIBOR

         With respect to each Interest Accrual Period, on the Interest
Determination Date, the Indenture Trustee will determine One-Month LIBOR for the
next Interest Accrual Period. If that rate does not appear on Telerate Page
3750, the rate for that day will be determined on the basis of the offered rates
of the Reference Banks (as defined in this prospectus supplement) for one-month
U.S. dollar deposits, as of 11:00 a.m. (London time) on that Interest
Determination Date. The Indenture Trustee will request the principal London
office of each of the Reference Banks to provide a quotation of its rate. If on
that Interest Determination Date two or more Reference Banks provide those
offered quotations, One-Month LIBOR for the related Interest Accrual Period
shall be the arithmetic mean of those offered quotations (rounded upwards if
necessary to the nearest whole multiple of 0.0625%). If on that Interest
Determination Date fewer than two Reference Banks provide those offered
quotations, One-Month LIBOR for the related Interest Accrual Period shall be the
higher of (x) One-Month LIBOR as determined on the previous Interest
Determination Date and (y) the Reserve Interest Rate (as defined in this
prospectus supplement).

         As used in this section, "business day" means a day on which banks are
open for dealing in foreign currency and exchange in London and New York City.

         The establishment of One-Month LIBOR on each Interest Determination
Date by the Indenture Trustee and the Indenture Trustee's calculation of the
rate of interest applicable to the notes for the related Interest Accrual Period
shall (in the absence of manifest error) be final and binding.

PRINCIPAL PAYMENTS ON THE NOTES

         On each Payment Date, the Principal Payment Amount will be distributed
to the holders of the notes then entitled to payments of principal. In no event
will the Principal Payment Amount with respect to any Payment Date be (x) less
than zero or (y) greater than the then-outstanding aggregate Note Balance of the
notes. The Principal Payment Amount for the first Payment Date will include
approximately $_________ collected by the Servicers in respect of prepayments on
the mortgage loans during the _________ ____ Prepayment Period.


                                      S-41


         On each Payment Date (a) prior to the Stepdown Date or (b) on which a
Trigger Event is in effect, the Principal Payment Amount shall be distributed:
first, to the Class A Notes, until the Note Balance thereof has been reduced to
zero; second, to the Class M-1 Notes, until the Note Balance thereof has been
reduced to zero; third, to the Class M-2 Notes, until the Note Balance thereof
has been reduced to zero; and fourth, to the Class M-3 Notes, until the Note
Balance thereof has been reduced to zero.

         On each Payment Date (a) on or after the Stepdown Date and (b) on which
a Trigger Event is not in effect, the holders of the Class A Notes and the
Subordinate Notes shall be entitled to receive payments in respect of principal
to the extent of the Principal Payment Amount in the following amounts and order
of priority:

         FIRST, the lesser of (x) the Principal Payment Amount and (y) the Class
         A Principal Payment Amount, shall be distributed to the holders of the
         Class A Notes, until the Note Balance thereof has been reduced to zero;

         SECOND, the lesser of (x) the excess of (i) the Principal Payment
         Amount over (ii) the amount distributed to the holders of the Class A
         notes pursuant to clause first above and (y) the Class M-1 Principal
         Payment Amount, shall be distributed to the holders of the Class M-1
         Notes, until the Note Balance thereof has been reduced to zero;

         THIRD, the lesser of (x) the excess of (i) the Principal Payment Amount
         over (ii) the sum of the amounts distributed to the holders of the
         Class A Notes pursuant to clause first above and to the holders of the
         Class M-1 Notes pursuant to clause second above and (y) the Class M-2
         Principal Payment Amount, shall be distributed to the holders of the
         Class M-2 Notes, until the Note Balance thereof has been reduced to
         zero; and

         FOURTH, the lesser of (x) the excess of (i) the Principal Payment
         Amount over (ii) the sum of the amounts distributed to the holders of
         the Class A Notes pursuant to clause first above, to the holders of the
         Class M-1 Notes pursuant to clause second above and to the holders of
         the Class M-2 Notes pursuant to clause third above and (y) the Class
         M-3 Principal Payment Amount, shall be distributed to the holders of
         the Class M-3 Notes, until the Note Balance thereof has been reduced to
         zero.

         On the Final Maturity Date or the Payment Date immediately following
the acceleration of the notes due to any Event of Default principal will be
payable on each class of notes in an amount equal to the Note Balance thereof on
that Payment Date. On the Final Maturity Date or the Payment Date immediately
following the acceleration of the notes due to any Event of Default, amounts in
respect of accrued interest, Interest Carry Forward Amounts and Allocated
Realized Loss Amounts will also be payable on each class of notes in the
priorities listed in the Indenture. There can be no assurance, however, that
sufficient funds will be available on that date to retire the Note Balances and
pay those other amounts.

         The allocation of payments in respect of principal to the Class A Notes
on each Payment Date (a) prior to the Stepdown Date or (b) on which a Trigger
Event has occurred, will have the effect of accelerating the amortization of the
Class A Notes while, in the absence of Realized Losses, increasing the
respective percentage interest in the principal balance of the mortgage loans


                                      S-42


evidenced by the Subordinate Notes and the Overcollateralized Amount. Increasing
the respective percentage interest in the Trust Estate of the Subordinate Notes
and the Overcollateralized Amount relative to that of the Class A Notes is
intended to preserve the availability of the subordination provided by the
Subordinate Notes and the Overcollateralized Amount.

         The holders of the Equity Certificates will be entitled to all
Prepayment Charges received on the mortgage loans and those amounts will not be
available for distribution on the notes.

CREDIT ENHANCEMENT

         The Credit Enhancement provided for the benefit of the holders of the
notes consists of subordination, as described below, and overcollateralization,
as described under "--OVERCOLLATERALIZATION PROVISIONS" in this prospectus
supplement.

         [Additional information with respect to credit enhancement providers,
required pursuant to Item 1114(b) of Regulation AB, will be provided if
applicable.]

         The rights of the holders of the Subordinate Notes and the Equity
Certificates to receive payments will be subordinated, to the extent described
in this prospectus supplement, to the rights of the holders of the Class A
Notes. This subordination is intended to enhance the likelihood of regular
receipt by the holders of the Class A Notes of the full amount of interest and
principal to which they are entitled and to afford those holders protection
against Realized Losses.

         The protection afforded to the holders of the Class A Notes by means of
the subordination of the Subordinate Notes and the Equity Certificates will be
accomplished by (i) the preferential right of the holders of the Class A Notes
to receive on any Payment Date, prior to payment on the Subordinate Notes and
the Equity Certificates, payments in respect of interest and principal, subject
to available funds, and (ii) if necessary, the right of the holders of the Class
A Notes to receive future payments of amounts that would otherwise be payable to
the holders of the Subordinate Notes and the Equity Certificates.

         In addition, the rights of the holders of Subordinate Notes with lower
numerical class designations will be senior to the rights of holders of
Subordinate Notes with higher numerical class designations, and the rights of
the holders of all of the Subordinate Notes to receive payments in respect of
the mortgage loans will be senior to the rights of the holders of the Equity
Certificates, in each case to the extent described in this prospectus
supplement. This subordination is intended to enhance the likelihood of regular
receipt by the holders of Subordinate Notes with lower numerical class
designations relative to the holders of Subordinate Notes with higher numerical
class designations (and by the holders of all of the Subordinate Notes relative
to the holders of the Equity Certificates) of the full amount of interest and
principal to which they are entitled and to afford those holders protection
against Realized Losses, as described under "--Allocation of Realized Losses" in
this prospectus supplement.


                                      S-43


OVERCOLLATERALIZATION PROVISIONS

         The weighted average mortgage rate for the mortgage loans (adjusted to
reflect the Master Servicing Fee, the Servicing Fees and the Indenture Trustee
Fee payable from interest received or advanced on the mortgage loans) is
generally expected to be higher than the weighted average of the Note Interest
Rates on the notes, thus generating excess interest collections which, in the
absence of Realized Losses, will not be necessary to fund interest payments on
the notes. The Indenture requires that, on each Payment Date, the Net Monthly
Excess Cashflow, if any, be applied on that Payment Date as an accelerated
payment of principal on class or classes of notes then entitled to receive
payments in respect of principal, but only to the limited extent hereafter
described. With respect to any Payment Date, any Net Monthly Excess Cashflow
(or, in the case of clause first below, the Net Monthly Excess Cashflow
exclusive of any Overcollateralization Reduction Amount) shall be paid as
follows:

         FIRST, to the holders of the class or classes of notes then entitled to
         receive payments in respect of principal, in an amount equal to the
         principal portion of any Realized Losses incurred or deemed to have
         been incurred on the mortgage loans;

         SECOND, to the holders of the class or classes of notes then entitled
         to receive payments in respect of principal, in an amount equal to the
         Overcollateralization Increase Amount;

         THIRD, to the holders of the Class A Notes, in an amount equal to the
         Interest Carry Forward Amount for those notes;

         FOURTH, to the holders of the Class M-1 Notes, in an amount equal to
         the Interest Carry Forward Amount for those notes;

         FIFTH, to the holders of the Class M-1 Notes, in an amount equal to the
         Allocated Realized Loss Amount for those notes;

         SIXTH, to the holders of the Class M-2 Notes, in an amount equal to the
         Interest Carry Forward Amount for those notes; SEVENTH, to the holders
         of the Class M-2 Notes, in an amount equal to the Allocated Realized
         Loss Amount for those notes;

         EIGHTH, to the holders of the Class M-3 Notes, in an amount equal to
         the Interest Carry Forward Amount for those notes;

         NINTH, to the holders of the Class M-3 Notes, in an amount equal to the
         Allocated Realized Loss Amount for those notes; and

         TENTH, to the holders of the Equity Certificates as provided in the
         Indenture.

         With respect to any Payment Date, the excess, if any, of (a) the
aggregate principal balance of the mortgage loans immediately following that
Payment Date over (b) the Note Balance of the notes, after taking into account
the payment of the amounts described in clauses (b)(i) through (iv) of the
definition of Principal Payment Amount on that Payment Date, is the
"Overcollateralized Amount" for the notes as of that Payment Date. As of the
Closing Date, the aggregate principal balance of the mortgage loans as of the
Cut-off Date will exceed the


                                      S-44


aggregate Note Balance of the notes by an amount equal to approximately
$_________. That amount represents approximately ____% of the aggregate
principal balance of the mortgage loans as of the Cut-off Date, which is the
initial amount of overcollateralization required to be provided by the mortgage
pool under the Indenture. Under the Indenture, the Overcollateralized Amount is
required to be maintained at the Required Overcollateralized Amount. In the
event that Realized Losses are incurred on the mortgage loans, those Realized
Losses may result in an overcollateralization deficiency since those Realized
Losses will reduce the principal balance of the mortgage loans without a
corresponding reduction to the aggregate Note Balance of the notes. In that
event, the Indenture requires the payment from Net Monthly Excess Cashflow,
subject to available funds, of an amount equal to that overcollateralization
deficiency, which shall constitute a principal payment on the notes in reduction
of the Note Balances thereof. This has the effect of accelerating the
amortization of the notes relative to the amortization of the mortgage loans,
and of increasing the Overcollateralized Amount.

         On and after the Stepdown Date and provided that a Trigger Event is not
in effect, the Required Overcollateralized Amount may be permitted to decrease,
or "step down", below the initial $_________ level to a level equal to
approximately ____% of the then current aggregate outstanding principal balance
of the mortgage loans (after giving effect to principal payments to be
distributed on that Payment Date), subject to a floor of $_________. In the
event that the Required Overcollateralized Amount is permitted to step down on
any Payment Date, the Indenture provides that a portion of the principal which
would otherwise be distributed to the holders of the notes on that Payment Date
shall be distributed to the holders of the Equity Certificates, subject to the
priorities listed above. With respect to that Payment Date, the Principal
Payment Amount will be reduced by the Overcollateralization Reduction Amount
after taking into account all other payments to be made on that Payment Date,
which amount shall be distributed as Net Monthly Excess Cashflow pursuant to the
priorities listed above. This has the effect of decelerating the amortization of
the notes relative to the amortization of the mortgage loans, and of reducing
the Overcollateralized Amount. However, if on any Payment Date a Trigger Event
is in effect, the Required Overcollateralized Amount will not be permitted to
step down on that Payment Date.

ALLOCATION OF LOSSES; SUBORDINATION

         With respect to any defaulted mortgage loan that is finally liquidated
through foreclosure sale, disposition of the related mortgaged property (if
acquired by deed in lieu of foreclosure) or otherwise, the amount of loss
realized, if any, will equal the portion of the unpaid principal balance
remaining, if any, plus interest on that mortgage loan through the last day of
the month in which that mortgage loan was finally liquidated, after application
of all amounts recovered (net of amounts reimbursable to the Servicers for P&I
Advances, servicing advances and Servicing Fees) towards interest and principal
owing on the mortgage loan.

         Any Realized Loss on the mortgage loans will be allocated on any
Payment Date, first, to Net Monthly Excess Cashflow, second, to the
Overcollateralized Amount, third, to the Class M-3 Notes, fourth, to the Class
M-2 Notes, and fifth, to the Class M-1 Notes. The Indenture does not permit the
allocation of Realized Losses to the Class A Notes. Investors in the Class A
Notes should note that although Realized Losses cannot be allocated to those
notes, under various loss


                                      S-45


scenarios there will not be enough principal and interest collected on the
mortgage loans to pay the Class A Notes all interest and principal amounts to
which they are then entitled.

         Once Realized Losses have been allocated to the Subordinate Notes,
those Realized Losses will not be reinstated thereafter. However, Allocated
Realized Loss Amounts may be paid to the holders of those classes of notes,
after various distributions to the holders of the Class A Notes and Subordinate
Notes with lower numerical class designations, but before the Equity
Certificates are entitled to any distributions.

         Any allocation of a Realized Loss to a note will be made by reducing
the Note Balance thereof by the amount so allocated on the Payment Date in the
month following the calendar month in which that Realized Loss was incurred.
Notwithstanding anything to the contrary described in this prospectus
supplement, in no event will the Note Balance of any note be reduced more than
once in respect of any particular amount both (i) allocable to those notes in
respect of Realized Losses and (ii) payable as principal to the holder of those
notes from Net Monthly Excess Cashflow.

P&I ADVANCES

         Subject to the following limitations, each Servicer will be obligated
to advance or cause to be advanced on or before each Payment Date from its own
funds, or funds in the Certificate Account that are not included in the
Available Payment Amount for that Payment Date, any P&I Advance.

         P&I Advances are required to be made only to the extent they are deemed
by the related Servicer to be recoverable from related late collections,
insurance proceeds or liquidation proceeds. The purpose of making those P&I
Advances is to maintain a regular cash flow to the noteholders, rather than to
guarantee or insure against losses. The Servicers will not be required to make
any P&I Advances with respect to reductions in the amount of the monthly
payments on the mortgage loans due to bankruptcy proceedings or the application
of the Relief Act.

         All P&I Advances will be reimbursable to the related Servicer from late
collections, insurance proceeds and liquidation proceeds from the mortgage loan
as to which that unreimbursed P&I Advance was made. In addition, any P&I
Advances previously made in respect of any mortgage loan that are deemed by the
related Servicer to be nonrecoverable from related late collections, insurance
proceeds or liquidation proceeds may be reimbursed to the related Servicer out
of any funds in the Certificate Account prior to the payments on the notes. In
the event that any Servicer fails in its obligation to make any required
advance, the Master Servicer will be obligated to make that advance, and in the
event that the Master Servicer fails in its obligation to make that advance, the
Indenture Trustee will be obligated to make that advance, in each of these cases
to the extent required in the related Servicing Agreement.

TABLE OF FEES AND EXPENSES

         The following table indicates the fees and expenses to be paid from the
cash flows from the mortgage loans and other assets of the trust fund, while the
Notes are outstanding.


                                      S-46


         All fees are expressed in basis points, at an annualized rate, applied
to the outstanding aggregate principal balance of the mortgage loans.

                  fee that covers all of these functions. The Master Servicer
                  performs these functions.
         (2)      Master Servicer pays trustee and servicer fees out of its fee.

         The Indenture Trustee, prior to the occurrence of an Event of Default
and after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in the Indenture.

         If an Event of Default has occurred and has not been cured or waived,
the Indenture Trustee shall exercise such rights and powers vested in it by the
Indenture, using the same degree of care and skill in their exercise, as a
prudent person would exercise under the circumstances in the conduct of his own

Trustee, unless such Event of Default shall have been waived or cured.

         The Indenture will provide that the Indenture Trustee may withdraw
funds from the Certificate Account (i) to reimburse itself for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection and
including reasonable compensation and expenses, disbursements and advances of
its agents, counsel, accountants and experts and (ii) to reimburse the Owner
Trustee for all reasonable out-of pocket expenses incurred or made by the Owner
Trustee for all services rendered by the Owner Trustee it in the Owner Trustee's

assets of the Trust Estate) shall indemnify the Indenture Trustee against any
and all loss, liability or expense (including reasonable attorneys' fees)
incurred by the Indenture Trustee in connection with the administration of the
Trust Estate and the performance of the Indenture Trustee's duties under this

                            THE SERVICING AGREEMENTS

         The following summary describes a number of terms of the Servicing
Agreements, dated as of __________ __, ____, among the Issuing Entity, the
Indenture Trustee, the Master Servicer and the related Servicer. The summary
does not purport to be complete and is subject to, and qualified in its entirety
by reference to, the provisions of the Servicing Agreements. Whenever particular
sections or defined terms of the Servicing Agreements are referred to, those
sections or defined terms are incorporated in this prospectus supplement by
reference. The depositor will provide to a prospective or actual noteholder
without charge, on written request, a copy (without exhibits) of the Servicing
Agreements. Requests should be addressed to the Secretary, Impac Secured Assets
Corp., 1401 Dove Street, Newport Beach, CA 92660 and its phone number is (949)
475-3600.

THE MASTER SERVICER AND THE SERVICERS

GENERAL

         Impac Funding Corporation, referred to in this prospectus supplement as
Impac Funding Corporation or the Master Servicer, will act as the Master
Servicer of the mortgage loans


                                      S-50


pursuant to the Servicing Agreement, referred to herein as the Agreement, dated
as of the Cut-off Date, among the Depositor, the Sponsor, the Master Servicer
and the IndentureTrustee.

         Primary servicing of the mortgage loans will be provided for in
accordance with the Servicing Agreement or similar agreements, which are
collectively referred to in this prospectus supplement as the Servicing
Agreements. Each of the Servicing Agreements will be assigned to the trust
pursuant to various assignment, assumption and recognition agreements among the
related Servicer, the Sponsor and the Indenture Trustee on behalf of the
Noteholders; provided, however, that the Sponsor will retain the right to
enforce the representations and warranties made by the Servicers with respect to
the related mortgage loans against them. In the event of a default by a Servicer
under the related Servicing Agreement, the Master Servicer will be required to
enforce any remedies against the Servicer, and shall either find a successor
Servicer or shall assume primary servicing obligations for the related mortgage
loans itself.

         The Servicer or the Master Servicer, directly or through subservicers,
as the case may be, will make reasonable efforts to collect all payments called
for under the loans and will, consistent with the related servicing agreement
and any applicable insurance policy, FHA insurance or other credit enhancement,
follow the collection procedures that are normal and usual in its general loan
servicing activities for assets that are comparable to the loans. Consistent
with the previous sentence, the Servicer or the Master Servicer may, in its
discretion, waive any prepayment charge in connection with the prepayment of a
loan or extend the due dates for payments due on a mortgage note, provided that
the insurance coverage for the loan or any coverage provided by any alternative
credit enhancement will not be adversely affected by the waiver or extension.
The Master Servicer or Servicer may also waive or modify any term of a loan so
long as the Master Servicer or Servicer has determined that the waiver or
modification is not materially adverse to any securityholders, taking into
account any estimated loss that may result absent that action.

         In instances in which a loan is in default, or if default is reasonably
foreseeable, and if determined by the Master Servicer or Servicer to be in the
best interests of the related securityholders, the Master Servicer or Servicer
may engage, either directly or through subservicers, in a wide variety of loss
mitigation practices including waivers, modifications, payment forbearances,
partial forgiveness, entering into repayment schedule arrangements, and
capitalization of arrearages rather than proceeding with foreclosure or
repossession, if applicable. In making that determination, the estimated
Realized Loss that might result if the loan were liquidated would be taken into
account. Modifications may have the effect of, among other things, reducing the
loan rate, forgiving payments of principal, interest or other amounts owed under
the mortgage loan or contract, such as taxes or insurance premiums, extending
the final maturity date of the loan, capitalizing delinquent interest and other
amounts owed under the mortgage loan or contract, or any combination of these or
other modifications. Any modified loan may remain in the related trust, and the
reduction in collections resulting from a modification may result in reduced
distributions of interest or principal on, or may extend the final maturity of,
one or more classes of the related securities.

         The Servicers will be responsible for the servicing of the mortgage
loans covered by the related Servicing Agreement, and the Master Servicer will
be required to monitor their performance. All collections of principal and
interest on any mortgage loans, including but not


                                      S-51


limited to Principal Prepayments, Insurance Proceeds, Liquidation Proceeds (less
amounts reimbursable to the applicable Servicer out of Liquidation Proceeds in
accordance with the applicable Servicing Agreement), the Repurchase Price for
any mortgage loans repurchased, and advances made from the Servicer's own funds
(less the servicing fee) will be deposited in a Protected Account, held by a
designated depository institution and segregated on the books of such
institution in the name of the Indenture Trustee for the benefit of Noteholders.
Amounts on deposit in a Protected Account may be invested in Permitted
Investments in the name of the Indenture Trustee for the benefit of Noteholders
and, except as provided in the preceding paragraph, not commingled with any
other funds. Such Permitted Investments shall mature, or shall be subject to
redemption or withdrawal, no later than the date on which such funds are
required to be withdrawn for deposit in the Master Servicer Collection Account,
and shall be held until required for such deposit. The income earned from
Permitted Investments made shall be paid to the related Servicer under the
applicable Servicing Agreement, and the risk of loss of moneys required to be
distributed to the Noteholders resulting from such investments shall be borne by
and be the risk of the related Servicer. The related Servicer (to the extent
provided in the Servicing Agreement) shall deposit the amount of any such loss
in the Protected Account within two Business Days of receipt of notification of
such loss but not later than the second Business Day prior to the Distribution
Date on which the moneys so invested are required to be distributed to the
Noteholders. On the date specified in the related Servicing Agreement, the
related Servicer will withdraw or cause to be withdrawn from the applicable
Protected Accounts and any other permitted accounts and will remit to the Master
Servicer for deposit in the Master Servicer Collection Account the Available
Funds. SEE "DESCRIPTION OF THE SECURITIES-COLLECTION ACCOUNT" IN THE PROSPECTUS.

the Master Servicer and the Servicers has been provided by the respective party.

[ADDITIONAL SERVICERS]

         [Identification of, and information with respect to additional

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

         The Servicing Fee to be paid to each Servicer in respect of its
servicing activities for the notes will be equal to accrued interest at the
Servicing Fee Rate of ____% per annum with respect to each mortgage loan
serviced by it for each calendar month on the same principal balance on which
interest on that mortgage loan accrues for that calendar month. As additional
servicing compensation, each Servicer is entitled to retain all assumption fees
and late payment charges in respect of mortgage loans serviced by it, to the
extent collected from mortgagors, together with any interest or other income
earned on funds held in the Certificate Account (to the extent not payable as
compensation to the Indenture Trustee) and any escrow accounts in respect of
mortgage loans serviced by it.

         When a principal prepayment in full is made on a mortgage loan, the
mortgagor is charged interest only for the period from the Due Date of the
preceding monthly payment up to the date of that prepayment, instead of for a
full month. When a partial principal prepayment is made on a mortgage loan, the
mortgagor is not charged interest on the amount of that prepayment for the month
in which that prepayment is made. Each Servicer is obligated to pay Compensating
Interest from its own funds a Prepayment Interest Shortfall, but only to the
extent of its aggregate Servicing Fee for the related Due Period. Each Servicer
is obligated to pay various insurance premiums and ongoing expenses associated
with the mortgage pool in respect of mortgage loans serviced by it and incurred
by that Servicer in connection with its responsibilities under the related
Servicing Agreement and is entitled to reimbursement therefor as provided in
that Servicing Agreement. With respect to the mortgage loans serviced by
_________, _________ will also be entitled to reimbursement of servicing
advances and principal and interest advances made by it as servicer of those
mortgage loans prior to the Cut-off Date. SEE "DESCRIPTION OF THE
SECURITIES--RETAINED INTEREST; SERVICING COMPENSATION AND PAYMENT OF EXPENSES"
IN THE PROSPECTUS for information regarding expenses payable by the Servicers.

SALE OF DEFAULTED MORTGAGE LOANS

         If consent to the operation of the provisions described below shall
have been given by the related Servicer (unless the Directing Holder, as defined
below, is the Sponsor or an affiliate thereof, in which case that consent shall
not be required), then with respect to any mortgage loan that is delinquent in
excess of the number of days provided in the related Servicing Agreement, (i)
the Directing Holder may direct the related Servicer to commence foreclosure and
(ii) prior to commencement of foreclosure of any mortgage loan, that Servicer
will notify the Directing Holder of that proposed foreclosure in order to permit
the Directing


                                      S-55


Holder the right to instruct that Servicer to delay the proposed foreclosure. In
the case of the exercise by the Directing Holder of the right to direct the
related Servicer pursuant to either clause (i) or clause (ii) above, the
Directing Holder will provide to that Servicer the Loan Appraisal for each
related mortgaged property. Within two business days of instructing the related
Servicer to commence or delay foreclosure, the Directing Holder will deposit in
the related Collateral Account for the benefit of the noteholders an amount
equal to ___% of the Valuation (as defined below) of the related mortgage loan
plus three months' interest at the related mortgage rate. While foreclosure is
delayed pursuant to the direction of the Directing Holder, the Directing Holder
may direct the related Servicer to proceed with foreclosure at anytime.

         Upon the liquidation of the related mortgage loan or the disposition of
the related mortgaged property in accordance with the requirements provided in
the related Servicing Agreement, the related Servicer will calculate the amount,
if any, by which the Valuation exceeds the actual sales price obtained for the
related mortgage loan or the mortgaged property, as the case may be, and the
related Servicer will withdraw the amount of that excess from the Collateral
Account and deposit that amount into the related Certificate Account.

         If the amount realized pursuant to the above-described procedures
exceeds the Valuation, the related Servicer will deposit immediately upon
realization from those proceeds that excess into the Certificate Account. The
related Servicer shall apply all those amounts as additional liquidation
proceeds pursuant to the related Servicing Agreement. If any election to delay
foreclosure is to be extended for a period in excess of three months from the
Directing Holder's direction to the related Servicer to delay foreclosure, the
Directing Holder will be required to deposit in the Collateral Account in
advance the amount of each additional month's interest at the related mortgage
rate. If the above-described procedures do not result in the mortgage loan being
brought current within six months of the Directing Holder's direction to the
related Servicer to delay foreclosure, the Directing Holder will be required to
either (i) purchase the mortgage loan for a purchase price equal to the fair
market value thereof as shown on the Loan Appraisal or (ii) allow the related
Servicer to proceed with the commencement of foreclosure. Should the Directing
Holder elect to purchase the mortgage loan, the related Servicer will first
apply funds on deposit in the related Collateral Account towards that purchase
price; any shortage will be paid by the Directing Holder and any excess will be
returned to it.

         With respect to any mortgage loan as to which the Directing Holder has
directed the related Servicer to commence foreclosure or to delay foreclosure,
that Servicer may withdraw from the Collateral Account from time to time amounts
necessary to reimburse that Servicer for all P&I Advances and servicing advances
in accordance with the related Servicing Agreement. In the event that the
related mortgage loan is brought current, the amounts so withdrawn from the
Collateral Account by the related Servicer as reimbursement for P&I Advances or
servicing advances shall be redeposited in that Collateral Account by the
related Servicer and that Servicer shall be reimbursed as provided in the
related Servicing Agreement. Following foreclosure, liquidation, disposition or
the bringing current of the related mortgage loan, as applicable, all amounts
remaining in the Collateral Account will be released to the Directing Holder. In
the event that amounts on deposit in the Collateral Account are insufficient to
cover the withdrawals that the related Servicer is entitled to make for P&I
Advances, servicing advances or for deposit into the Certificate Account, the
Directing Holder will be obligated to pay those amounts to the related Servicer
for deposit into the Collateral Account. The Directing Holder may direct that
amounts on deposit in the Collateral Account be invested in Permitted
Investments. Interest or


                                      S-56


other income earned on funds in the Collateral Account will be paid to the
Directing Holder and the amount of any loss on those funds will be immediately
deposited into the Collateral Account by the Directing Holder when realized. The
Directing Holder will grant to the related Servicer for the benefit of the
noteholders a security interest in the Collateral Account, all amounts deposited
in that Collateral Account or invested in Permitted Investments, and all
proceeds of the foregoing.

         Notwithstanding the foregoing, the provisions described above shall not
be operative in the case of the mortgage loans serviced by ___________.

SERVICER EVENTS OF DEFAULT

         In addition to those Events of Default (as defined in the prospectus)
pertaining to the servicing of the mortgage loans and described under
"Description of the Securities--Events of Default" in the prospectus, upon the
occurrence of various loss triggers with respect to the mortgage loans, the
Servicer may be removed as servicer of the mortgage loans serviced by it in
accordance with the terms of the related Servicing Agreement. If any Servicer is
removed in connection with an Event of Default applicable to that Servicer under
the terms of the related Servicing Agreement, the Master Servicer will become
the successor Servicer of the mortgage loans serviced by that terminated
Servicer.

                     THE INDENTURE AND OWNER TRUST AGREEMENT

         The following summary describes some of the terms of the Indenture. The
summary does not purport to be complete and is subject to, and qualified in its
entirety by reference to, the provisions of the Owner Trust Agreement and
Indenture. Whenever particular defined terms of the Indenture are referred to,
those defined terms are incorporated in this prospectus supplement by reference.
The depositor will provide to a prospective or actual noteholder without charge,
on written request, a copy (without exhibits) of the Indenture and the Owner
Trust Agreement. Requests should be addressed to the Secretary, Impac Secured
Assets Corp., 1401 Dove Street, Newport Beach, CA 92660 and its phone number is
(949) 475-3600.

GENERAL

         The notes will be issued pursuant to the Indenture, a form of which is
filed as an exhibit to the registration statement. A Current Report on Form 8-K
relating to the notes containing a copy of the Indenture and the Owner Trust
Agreement as executed will be filed by the depositor with the Securities and
Exchange Commission within fifteen days of the initial issuance of the notes.
Reference is made to the prospectus for important information in addition to
that presented in this prospectus supplement regarding the Trust Estate, the
terms and conditions of the Indenture and the Owner Trust Agreement and the
notes. The notes will be transferable and exchangeable at the corporate trust
offices of the Indenture Trustee, located in _______________.


                                      S-57


ASSIGNMENT OF MORTGAGE LOANS

         On or prior to the date the notes are issued, the Sponsor will convey
each mortgage loan to __________, who in turn will convey each mortgage loan to
the depositor, who in turn will convey each mortgage loan to the Issuing Entity.

         At the time of issuance of the notes, the Issuing Entity will pledge
all of its right, title and interest in and to the mortgage loans, including all
principal and interest due on that mortgage loan after the Cut-off Dates,
without recourse, to the Indenture Trustee pursuant to the Indenture as
collateral for the notes; provided, however, that the Sponsor will reserve and
retain all its right, title and interest in and to principal and interest due on
that mortgage loan on or prior to the Cut-off Date (whether or not received on
or prior to the Cut-off Date), and to prepayments received prior to the Cut-off
Date. The Indenture Trustee, concurrently with that assignment, will
authenticate and deliver the notes at the direction of the Issuing Entity in
exchange for, among other things, the mortgage loans.

         The Indenture will require the Issuing Entity to deliver to the
Indenture Trustee or to a custodian with respect to each mortgage loan (i) the
mortgage note endorsed without recourse to the Indenture Trustee, (ii) the
original mortgage with evidence of recording indicated on that mortgage and
(iii) an assignment of the mortgage in recordable form to the Indenture Trustee.
Those assignments of mortgage loans are required to be recorded by or on behalf
of the Sponsor, at the expense of the Sponsor, in the appropriate offices for
real property records.

EVENTS OF DEFAULT

         Notwithstanding, the prospectus, if an Event of Default occurs and is
continuing, the Indenture Trustee or the holders of a majority of the Voting
Rights may declare the Note Balance of all the notes to be due and payable
immediately. That declaration may, under various circumstances, be rescinded and
annulled by the holders of a majority in aggregate outstanding Voting Rights.

         If following an Event of Default, the notes have been declared to be
due and payable, the Indenture Trustee may, in its discretion, notwithstanding
that acceleration, elect to maintain possession of the collateral securing the
notes and to continue to apply payments on that collateral as if there had been
no declaration of acceleration if that collateral continues to provide
sufficient funds for the payment of principal of and interest on the notes as
they would have become due if there had not been that declaration. In addition,
the Indenture Trustee may not sell or otherwise liquidate the collateral
securing the notes following an Event of Default, unless (a) the holders of 100%
of the then aggregate outstanding Voting Rights consent to that sale, (b) the
proceeds of that sale or liquidation are sufficient to pay in full the principal
of and accrued interest, due and unpaid at their respective Note Accrual Rates,
on the outstanding notes at the date of that sale or (c) the Indenture Trustee
determines that the collateral would not be sufficient on an ongoing basis to
make all payments on those notes as those payments would have become due if
those notes had not been declared due and payable, and the Indenture Trustee
obtains the consent of the holders of 66 2/3% of the then aggregate outstanding
Voting Rights.


                                      S-58


         In the event that the Indenture Trustee liquidates the collateral in
connection with an Event of Default, the Indenture provides that the Indenture
Trustee will have a prior lien on the proceeds of that liquidation for unpaid
fees and expenses. As a result, upon the occurrence of that Event of Default,
the amount available for payments to the noteholders would be less than would
otherwise be the case. However, the Indenture Trustee may not institute a
proceeding for the enforcement of its lien except in connection with a
proceeding for the enforcement of the lien of the Indenture for the benefit of
the noteholders after the occurrence of that Event of Default.

         In the event the principal of the notes is declared due and payable, as
described above, the holders of any those notes issued at a discount from par
may be entitled to receive no more than an amount equal to the unpaid principal
amount thereof less the amount of that discount that is unamortized.

         No noteholder will have any right under the Indenture to institute any
proceeding with respect to that Indenture unless (a) that holder previously has
given to the Indenture Trustee written notice of default and the continuance
thereof, (b) the holders of notes of any class evidencing not less than 25% of
the aggregate outstanding Note Balance constituting that class (i) have made
written request upon the Indenture Trustee to institute that proceeding in its
own name as Indenture Trustee under the Indenture and (ii) have offered to the
Indenture Trustee reasonable indemnity, (c) the Indenture Trustee has neglected
or refused to institute that proceeding for 60 days after receipt of that
request and indemnity and (d) no direction inconsistent with that written
request has been given to the Indenture Trustee during that 60 day period by the
holders of a majority of the Note Balance of that class. However, the Indenture
Trustee will be under no obligation to exercise any of the trusts or powers
vested in it by the Indenture or to institute, conduct or defend any litigation
under that Indenture or in relation thereto at the request, order or direction
of any of the holders of notes covered by that Indenture, unless those holders
have offered to the Indenture Trustee reasonable security or indemnity against
the costs, expenses and liabilities which may be incurred therein or thereby.

VOTING RIGHTS

         At all times, 100% of all Voting Rights will be allocated among the
holders of the Class A Notes (or, after the Class A Notes have been paid in
full, the class of Subordinate Notes then outstanding with the lowest numerical
class designation) in proportion to the then outstanding Note Balances of their
respective notes.

OPTIONAL REDEMPTION

         The circumstances under which the obligations created by the Indenture
will terminate in respect of the notes are described in "Description of the
Securities--Termination" in the prospectus.

         At its option, the majority holder of the Equity Certificates may
redeem the notes, in whole but not in part, on any Payment Date on or after the
Payment Date on which the aggregate Note Balance is reduced to less than 20% of
the aggregate initial Note Balance. That redemption will be paid in cash at a
price equal to the sum of (w) 100% of the aggregate Note Balance then
outstanding, (x) the aggregate of any Allocated Realized Loss Amounts on the
notes remaining


                                      S-59


unpaid immediately prior to that Payment Date, (y) the aggregate of the Interest
Payment Amounts on the notes for that Payment Date and (z) the aggregate of any
Interest Carry Forward Amounts for that Payment Date. Upon that redemption, the
remaining assets in the Trust Estate shall be released from the lien of the
Indenture.

         In addition, with respect to the ____-___ Mortgage Loans, the majority
holder of the Equity Certificates may at its option obtain the release of that
portion of the mortgage pool (together with any properties acquired in respect
thereof) remaining in the Trust Estate from the lien of the Indenture, and in
connection therewith effect a partial redemption of the notes, on any Payment
Date on or after the Payment Date following the Due Period in which the
aggregate principal balance of the ____-___ Mortgage Loans (and properties
acquired in respect thereof) remaining in the Trust Estate is reduced to less
than $_____________. The ____-___ Mortgage Loans have an aggregate principal
balance of approximately $__________ as of the Cut-off Date. That redemption
shall be paid in cash at a price generally equal to the sum of (x) 100% of the
then-outstanding principal balance of that mortgage loan plus accrued interest
on that mortgage loan at their respective mortgage rates through the last day of
the calendar month preceding the month in which that redemption occurs, (y) the
then fair market value of that property and (z) the amount of any servicing
advances reimbursable to the related Servicer in respect of those mortgage
loans. For purposes of payments on the notes and Equity Certificates on the
Payment Date of that redemption, that redemption price shall be applied by the
Indenture Trustee as a final liquidation of each of those mortgage loans and
properties. The redemption price relating to those properties, at their then
fair market value, may result in a shortfall in payment to, and/or the
allocation of Realized Losses to, one or more classes of the notes. Furthermore,
the Master Servicing Fee, the Servicing Fee and the Indenture Trustee Fee, as
well as expenses and reimbursements permitted to be paid from the assets of the
Trust Estate under the Indenture or the applicable Servicing Agreement, in each
case to the extent payable or reimbursable with respect to those mortgage loans,
will be payable from the amount received in respect of that redemption price and
therefore, as provided in the Indenture, will be excluded from the Available
Payment Amount for the Payment Date of that redemption.

         In no event will the trust created by the Indenture continue beyond the
expiration of 21 years from the death of the survivor of the persons named in

                                      S-60


         Any one or more of the following obligations or securities held in the
name of the Indenture Trustee for the benefit of the Noteholders will be

         (i) obligations of or guaranteed as to principal and interest by the
United States or any agency or instrumentality thereof when such obligations are
backed by the full faith and credit of the United States;

         (ii) repurchase agreements on obligations specified in clause (i)

short-term rating available;

         (iii) federal funds, certificates of deposit, demand deposits, time
deposits and bankers' acceptances (which shall each have an original maturity of
not more than 90 days and, in the case of bankers' acceptances, shall in no
event have an original maturity of more than 365 days or a remaining maturity of
more than 30 days) denominated in United States dollars of any U.S. depository
institution or trust company incorporated under the laws of the United States or
any state thereof or of any domestic branch of a foreign depository institution
or trust company; provided that the debt obligations of such depository
institution or trust company (or, if the only Rating Agency is Standard &
Poor's, in the case of the principal depository institution in a depository
institution holding company, debt obligations of the depository institution
holding company) at the date of acquisition thereof have been rated by each
Rating Agency in its highest short-term rating available; and provided further
that, if the only Rating Agency is Standard & Poor's and if the depository or
trust company is a principal subsidiary of a bank holding company and the debt
obligations of such subsidiary are not separately rated, the applicable rating
shall be that of the bank holding company; and, provided further that, if the
original maturity of such short-term obligations of a domestic branch of a
foreign depository institution or trust company shall exceed 30 days, the
short-term rating of such institution shall be A-1+ in the case of Standard &
Poor's if Standard & Poor's is the Rating Agency;

         (iv) commercial paper (having original maturities of not more than 365
days) of any corporation incorporated under the laws of the United States or any
state thereof which on the date of acquisition has been rated by Moody's and
Standard & Poor's in their highest short-term ratings available; provided that
such commercial paper shall have a remaining maturity of not more than 30 days;

         (v) a money market fund or a qualified investment fund rated by Moody's
in its highest long-term ratings available and rated AAAm or AAAm-G by Standard
& Poor's, including any such funds for which ___________ or any affiliate
thereof serves as an investment advisor, manager, administrator, shareholder,
servicing agent, and/or custodian or sub-custodian; and

         (vi) other obligations or securities that are acceptable to each Rating
Agency as a Permitted Investment hereunder and will not reduce the rating
assigned to any Class of Notes by such Rating Agency below the lower of the
then-current rating or the rating assigned to such Notes as of the Closing Date
by such Rating Agency, as evidenced in writing;


                                      S-61


         provided, however, that no instrument shall be a Permitted Investment
if it represents, either (1) the right to receive only interest payments with
respect to the underlying debt instrument or (2) the right to receive both
principal and interest payments derived from obligations underlying such
instrument and the principal and interest payments with respect to such
instrument provide a yield to maturity greater than 120% of the yield to
maturity at par of such underlying obligations.

                         FEDERAL INCOME TAX CONSEQUENCES

         Upon the issuance of the notes, Thacher Proffitt & Wood LLP, counsel to
the depositor, will deliver its opinion generally to the effect that based on
the application of existing law and assuming compliance with the Owner Trust
Agreement, for federal income tax purposes, (a) the notes will be characterized
as indebtedness and not as representing an ownership interest in the Trust
Estate or an equity interest in the Issuing Entity or the depositor and (b) the
Issuing Entity will not be (i) classified as an association taxable as a
corporation for federal income tax purposes, (ii) a "publicly traded
partnership" as defined in Treasury Regulation Section 1.7704 or (iii) a
"taxable mortgage pool" within the meaning of Section 7701(i) of the Code. The
notes will not be treated as having been issued with "original issue discount"
(as defined in the prospectus). The prepayment assumption that will be used in
determining the rate of amortization of market discount and premium, if any, for
federal income tax purposes will be based on the assumption that the mortgage
loans will prepay at a rate equal to __% CPR. No representation is made that the
mortgage loans will prepay at that rate or at any other rate. SEE "FEDERAL
INCOME TAX CONSEQUENCES" IN THE PROSPECTUS.

         The notes will not be treated as assets described in Section
7701(a)(19)(C) of the Code or "real estate assets" under Section 856(c)(4)(A) of
the Code. In addition, interest on the notes will not be treated as "interest on
obligations secured by mortgages on real property" under Section 856(c)(3)(B) of
the Code. The notes will also not be treated as "qualified mortgages" under
Section 860G(a)(3)(C) of the Code.

         Prospective investors in the notes should SEE "FEDERAL INCOME TAX
CONSEQUENCES" AND "STATE AND OTHER TAX CONSEQUENCES" in the prospectus for a
discussion of the application of some federal income and state and local tax
laws to the Issuing Entity and purchasers of the notes.

                             METHOD OF DISTRIBUTION

         Subject to the terms and conditions provided in the Underwriting
Agreement, dated ________ __, ____, the depositor has agreed to sell, and the
Underwriter has agreed to purchase the notes. The Underwriter is obligated to
purchase all notes of the respective classes offered by this prospectus
supplement if it purchases any. The Underwriter is an affiliate of the
depositor.

         The notes will be purchased from the depositor by the Underwriter and
will be offered by the Underwriter to the public from time to time in negotiated
transactions or otherwise at varying prices to be determined at the time of
sale. Proceeds to the depositor from the sale of the notes, before deducting
expenses payable by the depositor, will be approximately ___% of the aggregate
initial Note Balance of the notes. In connection with the purchase and sale of
the notes,


                                      S-62


the Underwriter may be deemed to have received compensation from the depositor
in the form of underwriting discounts.

         The offered notes are offered subject to receipt and acceptance by the
Underwriter, to prior sale and to the Underwriter's right to reject any order in
whole or in part and to withdraw, cancel or modify the offer without notice. It
is expected that delivery of the offered notes will be made through the
facilities of DTC on or about the Closing Date.

         The Underwriting Agreement provides that the depositor will indemnify
the Underwriter against some civil liabilities, including liabilities under the
Securities Act of 1933, as amended, or will contribute to payments the
Underwriter may be required to make in respect thereof.

                                SECONDARY MARKET

         There can be no assurance that a secondary market for the notes will
develop or, if it does develop, that it will continue. The primary source of
information available to investors concerning the notes will be the monthly
statements discussed in the prospectus under "Description of the
Securities--Reports to Securityholders", which will include information as to
the outstanding principal balance of the notes and the status of the applicable
form of credit enhancement. There can be no assurance that any additional
information regarding the notes will be available through any other source. In
addition, the depositor is not aware of any source through which price
information about the notes will be generally available on an ongoing basis. The
limited nature of that information regarding the notes may adversely affect the
liquidity of the notes, even if a secondary market for the notes becomes
available.

                                 LEGAL OPINIONS

         A number of legal matters relating to the notes will be passed upon for
the depositor and the Underwriter by Thacher Proffitt & Wood LLP, New York, New
York.

                                LEGAL PROCEEDINGS

         [There are no material legal proceedings pending against the Sponsor,
the Depositor, the Indenture Trustee, The Issuing Entity, the Master Servicer,
[any affiliated Servicer, any 20% concentration unaffiliated Servicer, any 20%
concentration Originator], the Custodians, or with respect to which the property
of any of the foregoing transaction parties is subject, that are material to the
Noteholders. No legal proceedings against any of the foregoing transaction
parties is known to be contemplated by governmental authorities, that are
material to the Noteholders.]

              AFFILIATIONS, RELATIONSHIPS AND RELATED TRANSACTIONS

         [There are no affiliations between the Sponsor, the Depositor or the
Issuing Entity and any of the Master Servicer, [any affiliated Servicer, any 20%
concentration unaffiliated Servicer], the Indenture Trustee, [any 10%
concentration Originator], [any credit enhancement provider or derivatives
counterparty], the Custodians. There are no affiliations among the Master
Servicer, [any affiliated Servicer, any 20% concentration unaffiliated
Servicer], the Indenture Trustee, [any 10% concentration Originator], [any
credit enhancement provider or


                                      S-63


derivatives counterparty], the Custodians. There are currently no business
relationships, agreements, arrangements, transactions or understandings between
(a) the Sponsor, the Depositor or the Issuing Entity and (b) any of the parties
referred to in the preceding sentence, or any of their respective affiliates,
that were entered into outside the normal course of business or that contain
terms other than would be obtained in an arm's length transaction with an
unrelated third party and that are material to the investor's understanding of
the Notes, or that relate to the Notes or the pooled assets. No such business
relationship, agreement, arrangement, transaction or understanding has existed
during the past two years.]

                                     RATINGS

         It is a condition of the issuance of the notes that the Class A Notes
be rated "AAA" by _____________ and "AAA" by _______________, that the Class M-1
Notes be rated at least "AA" by ____ and at least "AA" by ____, that the Class
M-2 Notes be rated at least "A" by ____ and at least "A" by _____ and that the
Class M-3 Notes be rated at least "BBB" by _____.

         The ratings of _____ and _____ assigned to the notes address the
likelihood of the receipt by noteholders of all payments to which those
noteholders are entitled, other than payments of interest to the extent of any
Interest Carry Forward Amounts. The rating process addresses structural and
legal aspects associated with the notes, including the nature of the underlying
mortgage loans. The ratings assigned to the notes do not represent any
assessment of the likelihood that principal prepayments will be made by the
mortgagors or the degree to which the rate of those prepayments will differ from
that originally anticipated. The ratings do not address the possibility that
noteholders might suffer a lower than anticipated yield due to non-credit
events.

         A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning rating organization. Each security rating should be evaluated
independently of any other security rating. In the event that the ratings
initially assigned to the notes are subsequently lowered for any reason, no
person or entity is obligated to provide any additional credit support or credit
enhancement with respect to the notes.

         The depositor has not requested that any rating agency rate the notes
other than as stated above. However, there can be no assurance as to whether any
other rating agency will rate the notes, or, if it does, what rating would be
assigned by another rating agency. A rating on the notes by another rating
agency, if assigned at all, may be lower than the ratings assigned to the notes
as stated above.

         The rating agencies have stated that it is their standard policy to
monitor ratings on publicly offered securities for which a rating has been
provided, as to each rating agency rating each class of Offered Notes in
accordance with the rating agencies' particular surveillance policies, unless
the Issuing Entity requests a rating without surveillance. A rating agency will
monitor the rating it issues on an ongoing basis and may update the rating after
conducting its regular review of the Issuing Entity's creditworthiness or after
conducting a review of the status of the rating upon becoming aware of any
information that might reasonably be expected to result in a change of rating.
The Depositor has not requested that any rating agency not monitor


                                      S-64


their ratings of the Offered Notes, and the Depositor has not requested that any
rating agency use any monitoring procedures other than their standard monitoring
procedures.

                                LEGAL INVESTMENT

         The Class A Notes and the Class M-1 Notes will constitute "mortgage
related securities" for purposes of SMMEA for so long as they are rated not
lower than the second highest rating category by a Rating Agency (as defined in
the prospectus) and, as such, will be legal investments for various entities to
the extent provided in SMMEA. SMMEA, however, provides for state limitation on
the authority of those entities to invest in "mortgage related securities",
provided that this restricting legislation was enacted prior to October 3, 1991.
Some states have enacted legislation which overrides the preemption provisions
of SMMEA. The Class M-2 Notes and the Class M-3 Notes will not constitute
"mortgage related securities" for purposes of SMMEA.

         The depositor makes no representations as to the proper
characterization of the notes for legal investment or other purposes, or as to
the ability of particular investors to purchase the notes under applicable legal
investment restrictions. These uncertainties may adversely affect the liquidity
of the notes. Accordingly, all institutions whose investment activities are
subject to legal investment laws and regulations, regulatory capital
requirements or review by regulatory authorities are encouraged to consult with
their legal advisors in determining whether and to what extent the notes
constitute a legal investment or are subject to investment, capital or other
restrictions.

         SEE "LEGAL INVESTMENT" IN THE PROSPECTUS.

"Description of the Securities--Reports to Securityholders" in the prospectus.

                              ERISA CONSIDERATIONS

         ERISA and Section 4975 of the Code impose certain requirements on Plans
(as defined in the prospectus) and on persons who are fiduciaries with respect
to such Plans. Any Plan fiduciary which proposes to cause a Plan to acquire any
of the Notes would be required to determine whether such an investment is
permitted under the governing Plan instruments and is prudent and appropriate
for the Plan in view of its overall investment policy and the composition and
diversification of its portfolio. The DOL (as defined in the prospectus) has
promulgated the DOL Regulations defining the term "Plan Assets" for purposes of
applying the general fiduciary responsibility provisions of ERISA and the
prohibited transaction provisions of ERISA and Section 4975 of the Code. Under
the DOL Regulations, generally, when a Plan acquires an "equity interest" in
another entity (such as the trust), the underlying assets of that entity may be
considered to be Plan Assets. The DOL Regulations provide that the term "equity
interest" means any interest in an entity other than an instrument which is
treated as indebtedness under applicable local law and which has no "substantial
equity features."

         As of the date hereof, the ratings of the Notes and the traditional
debt features of these Notes should cause these Notes to be treated as debt with
no "substantial equity features" under the DOL Regulations. There can be no
assurance given, however, that the Notes are or will be


                                      S-66


treated as debt and not "equity interests" under the DOL Regulations. Moreover,
the debt treatment of the Notes for ERISA purposes could change subsequent to
their issuance; that is, they could be treated as equity interests, if, for
example, the ratings of the Notes change. Because of the factual nature of
certain of the above-described provisions of ERISA, the Code and the DOL
Regulations, Plans or persons investing Plan Assets should carefully consider
whether such an investment might constitute or give rise to a prohibited
transaction under ERISA or the Code. Any Plan fiduciary which proposes to cause
a Plan to acquire any of the Notes is encouraged to consult with its counsel
with respect to the potential consequences under ERISA and the Code of the
Plan's acquisition and ownership of such Notes.

         In addition, ERISA and the Code prohibit certain transactions involving
the assets of a Plan and Parties in Interest (as defined in the prospectus) who
have certain specified relationships to the Plan. Accordingly, even if the Notes
are treated as indebtedness under the DOL Regulations, prior to making an
investment in the Notes, investing Plans should determine whether the Issuing
Entity, the Sponsor, the Depositor, any Underwriter, the Owner Trustee, the
Indenture Trustee, the Master Servicer, any other servicer, any administrator,
any provider of credit support, including the Derivative Counterparty, any owner
of the Notes, which could be transferred subsequent to the purchase of a Note by
a Plan, or any of their affiliates is a Party in Interest with respect to such
Plan and, if so, whether such transaction is covered by one or more statutory,
regulatory or administrative exemptions. Additionally, an investment of the
assets of a Plan in certain securities may cause the assets of the issuing
entity of those securities to be deemed "Plan Assets" of such Plan, and any
person with certain specified relationships to such issuing entity to be deemed
a Party in Interest with respect to the investing Plan.

         By acquiring a Note, each purchaser will be deemed to represent that
either (1) it is not acquiring the Note with the assets of a Plan; or (2) (A)
the acquisition, holding and transfer of the Note will not give rise to a
non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of
the Code and (B) the Notes are rated investment grade or better and such person
believes that the Notes are properly treated as indebtedness without substantial
equity features for purposes of the DOL Regulations, and agrees to so treat the
Notes. Alternatively, regardless of the rating of the Notes, such person may
provide the Indenture Trustee and the Owner Trustee with an opinion of counsel,
which opinion of counsel will not be at the expense of the Issuing Entity, the
Sponsor, the Depositor, any Underwriter, the Owner Trustee, the Indenture
Trustee, the Master Servicer or any successor servicer which opines that the
acquisition, holding and transfer of such Note or interest therein is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Issuing Entity, the Sponsor, the Depositor, any Underwriter, the
Owner Trustee, the Indenture Trustee, the Master Servicer or any successor
servicer to any obligation in addition to those undertaken in the Indenture.

circumstances, to indemnify their directors, officers, employees and agents in
connection with threatened, pending or completed actions or proceedings brought

Certificateholders or the Noteholders for any action taken or for refraining
from the taking of any action pursuant to the Pooling and Servicing Agreement,
the Servicing Agreement, Indenture or Owner Trust Agreement, as applicable,
except for such person's own misfeasance, bad faith or gross negligence in the
performance of duties. The Pooling and Servicing Agreement with respect to each
series of Certificates, and the Servicing Agreements, Indentures, and Owner
Trust Agreements with respect to each series of Notes, will provide further

of the Company will be indemnified and held harmless against any loss, liability
or expense incurred in connection with any legal action relating to such Pooling
and Servicing Agreement, Servicing Agreements, Indentures and Owner Trust
Agreements, the related Certificates and Notes, other than any loss, liability
or expense (i) related to any specific Mortgage Loan or Mortgage Loans (except
as any such loss, liability or expense shall be otherwise reimbursable pursuant
to such agreements), (ii) incurred in connection with any violation by him or
her of any state or federal securities law or (iii) imposed by any taxing
authority if such loss, liability or expense is not specifically reimbursable
pursuant to the terms of such agreements.

                                    Statement; and

                                    (B) Each prospectus required to be filed

                                    was part of this Registration Statement or

                  The undersigned registrant undertakes that in a primary
                  offering of securities of the undersigned registrant pursuant
                  to this Registration Statement, regardless of the underwriting
                  method used to sell the securities to the purchaser, if the
                  securities are offered or sold to such purchaser by means of
                  any of the following


                                      II-4


                  communications, the undersigned registrant will be a seller to
                  the purchaser and will be considered to offer or sell such
                  securities to such purchaser:

                          (i)       Any preliminary prospectus or prospectus of
                                    the undersigned registrant relating to the
                                    offering required to be filed pursuant to
                                    Rule 424;

                          (ii)      Any free writing prospectus relating to the
                                    offering prepared by or on behalf of the
                                    undersigned registrant or used or referred
                                    to by the undersigned registrant;

                          (iii)     The portion of any other free writing
                                    prospectus relating to the offering
                                    containing material information about the
                                    undersigned registrant or its securities
                                    provided by or on behalf of the undersigned
                                    registrant; and

                          (iv)      Any other communication that is an offer in
                                    the offering made by the undersigned
                                    registrant to the purchaser.

                  (b) The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in this Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

                  (c) Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, managers, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, manager,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, manager, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.

                  (d) The Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
annual report pursuant to section 13(a) or section 15(d) of the Securities
Exchange Act of 1934 of a third party that is incorporated by reference in the
registration statement in accordance with Item 1100(c)(1) of Regulation AB shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.


                                      II-5


                  (e) The Registrant hereby undertakes that, except as otherwise
provided by Item 1105 of Regulation AB, information provided in response to that
Item pursuant to Rule 312 of Regulation S-T through the specified Internet
address in the prospectus is deemed to be a part of the prospectus included in
the registration statement. In addition, the Registrant hereby undertakes to
provide to any person without charge, upon request, a copy of the information
provided in response to Item 1105 of Regulation AB pursuant to Rule 312 of
Regulation S-T through the specified Internet address as of the date of the
prospectus included in this Registration Statement if a subsequent update or
change is made to the information.



                                      II-6



                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
