      of up to 5%, as described in this prospectus supplement.

(2)   Interest will accrue on the Class 1-XA Certificates based upon a notional
      amount. On any distribution date, the class notional amount of the Class
      1-XA Certificates will be equal to the sum of the class principal amounts
      of the Class 1-A1 and Class 1-A2 Certificates immediately prior to such
      distribution date. Interest will accrue on the Class 1-XA Certificates as
      described in this prospectus supplement under "Description of the
      Certificates -- Distributions of Interest." Distributions on the Class
      1-XA Certificates may be reduced on any distribution date to the extent
      basis risk shortfalls are experienced on the Class 1-A1 and Class 1-A2
      Certificates, and as otherwise described herein. No principal will be
      distributed on the Class 1-XA Certificates.

(3)   Interest will accrue on the Class 1-XB Certificates based upon a notional
      amount. On any distribution date, the class notional amount of the Class
      1-XB Certificates will be equal to the sum of the class principal amounts
      of the Class 1-B1 and Class 1-B2 Certificates immediately prior to such
      distribution date. Interest will accrue on the Class 1-XB Certificates as
      described in this prospectus supplement under "Description of the
      Certificates -- Distributions of Interest." Distributions on the Class
      1-XB Certificates may be reduced on any Distribution Date to the extent
      basis risk shortfalls are experienced on the Class 1-B1 and Class 1-B2
      Certificates, and as otherwise described herein. No principal will be
      distributable on the Class 1-XB Certificates.

(4)   Interest will accrue on the Class 1-A1, Class 1-A2, Class 1-B1 and Class
      1-B2 Certificates based upon one-month LIBOR plus a specified margin,
      subject to limitation, as described in this prospectus supplement.
      One-month LIBOR, for the initial accrual period will be determined two
      business days prior to the closing date and will be reset every month, as
      described under "Description of the Certificates -- Distributions of
      Interest -- Determination of LIBOR."

(5)   Interest will accrue on the Class 1-AR and Class 1-B3 Certificates based
      upon the weighted average of the net interest rates of the mortgage loans
      in pool 1, as described in this prospectus supplement.

(6)   Interest will accrue on the Class 2-A1, Class 2-A2, Class 2-AR, Class
      2-B1, Class 2-B2 and Class 2-B3 Certificates based upon the weighted
      average of the net interest rates of the mortgage loans in pool 2, as
      described in this prospectus supplement.

      The certificates offered by this prospectus supplement, except for the
Class 1-AR and Class 2-AR Certificates, will be issued in book-entry form and in
the minimum denominations (or multiples thereof) set forth under "Description of
the Certificates -- General" in this prospectus supplement. The Class 1-AR and
Class 2-AR Certificates will be issued in fully registered definitive form.

      The certificates represent ownership interests in a trust fund which will
consist primarily of two separate pools of mortgage loans, "pool 1" and "pool
2."

      Each class of the certificates will have different characteristics, some
of which are reflected in the following general designations:

      -     group 1 senior certificates: Class 1-A1, Class 1-A2, Class 1-XA,
            Class 1-XB and Class 1-AR Certificates.

      -     group 1 subordinate certificates: Class 1-B1, Class 1-B2, Class
            1-B3, Class 1-B4, Class 1-B5 and Class 1-B6 Certificates.

      -     group 1 certificates: the group 1 senior certificates and the group
            1 subordinate certificates.

      -     group 2 senior certificates: Class 2-A1, Class 2-A2 and Class 2-AR
            Certificates.

      -     group 2 subordinate certificates: Class 2-B1, Class 2-B2, Class
            2-B3, Class 2-B4, Class 2-B5 and Class 2-B6 Certificates.

      -     group 2 certificates: the group 2 senior certificates and the group
            2 subordinate certificates.

      -     senior certificates : the group 1 senior certificates and the group
            2 senior certificates.

      -     subordinate certificates: the group 1 subordinate certificates and
            the group 2 subordinate certificates.

      -     LIBOR certificates: the Class 1-A1, Class 1-A2, Class 1-B1 and
            Class 1-B2 Certificates.

      Distributions of principal and interest on the group 1 certificates (other
than the Class 1-XA and Class 1-XB Certificates) and distributions of interest
on the Class 1-XA and Class 1-XB Certificates will be based solely on
collections from the pool 1 mortgage loans. Distributions of principal and
interest on the group 2 certificates will be based solely on collections from
the pool 2 mortgage loans.

                                    THE TRUST

      Sequoia Mortgage Trust 2005-4 will be formed pursuant to a pooling and
servicing agreement among the depositor,

                                      S-2


the master servicer, the securities administrator and the trustee. The
certificates represent solely beneficial ownership interests in the trust fund
created under the pooling and servicing agreement and not an interest in, or the
obligation of, the depositor or any other person.

                                   THE TRUSTEE

      HSBC Bank USA, National Association, a national banking association, will
act as trustee of the trust under the pooling and servicing agreement.

                                 THE ORIGINATORS

      As of the cut-off date, approximately 62.38%, 15.57% and 13.65% of the
mortgage loans in pool 1 were originated by Morgan Stanley Credit Corporation
(formerly Morgan Stanley Dean Witter Credit Corporation), Merrill Lynch Mortgage
Corporation and Countrywide Home Loans, Inc., respectively. All of the mortgage
loans in pool 2 were originated by Wells Fargo Bank, N.A. The remainder of the
mortgage loans were originated by various mortgage lending institutions.

      We refer you to "Description of the Mortgage Pools -- Underwriting
Standards" in this prospectus supplement for more information.

                                   THE SELLER

      RWT Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of
Redwood Trust, Inc., has previously acquired the mortgage loans, directly or
indirectly, from the originators. On the closing date, RWT Holdings, Inc., as
seller, will sell all of its interest in the mortgage loans to the depositor.

                                  THE DEPOSITOR

      On the closing date, Sequoia Residential Funding, Inc., a Delaware
corporation and indirect wholly-owned subsidiary of Redwood Trust, Inc., will
assign all of its interest in the mortgage loans to the trustee for the benefit
of certificateholders.

                                  THE CUSTODIAN

      Wells Fargo Bank, N. A. will maintain custody of the mortgage files
relating to the mortgage loans on behalf of the trust.

                               THE MASTER SERVICER

      Wells Fargo Bank, N.A.

                                  THE SERVICERS

      The servicers of the mortgage loans will include Morgan Stanley Credit
Corporation (formerly Morgan Stanley Dean Witter Credit Corporation), PHH
Mortgage Corporation, Countrywide Home Loans Servicing L.P. and various other
servicers.

      All of the mortgage loans in pool 2 will initially be serviced by Wells
Fargo Bank, N.A.

      Servicing may subsequently be transferred to other servicers, in
accordance with the pooling and servicing agreement and the servicing
agreements, as described in this prospectus supplement.

      The servicers will service the mortgage loans pursuant to existing
servicing agreements between each such servicer and the seller. The rights of
the seller under each such servicing agreement will be assigned to the
depositor, and the depositor, in turn, will assign such rights to the trustee
for the benefit of certificateholders.

                                      S-3


      We refer you to "Servicing of the Mortgage Loans" in this prospectus
supplement for more information.

                          THE SECURITIES ADMINISTRATOR

      Wells Fargo Bank, N. A.

                                  CUT-OFF DATE

      September 1, 2005. The cut-off date is the date after which the trust fund
will be entitled to receive all collections on and proceeds of the mortgage
loans.

                                DISTRIBUTION DATE

      The 20th day of each month or, if such day is not a business day, the next
business day thereafter, commencing in October 2005. Distributions on each
distribution date will be made to certificateholders of record as of the related
record date, except that the final distribution on the certificates will be made
only upon presentment and surrender of the certificates at the corporate trust
office of the trustee.

                                   RECORD DATE

      With respect to the LIBOR certificates, the last business day preceding a
distribution date (or the closing date, in the case of the first distribution
date), unless such certificates are no longer book-entry certificates, in which
case the record date is the last business day of the month preceding the month
of a distribution date. With respect to all other classes of certificates, the
record date will be last business day of the month preceding the month of a
distribution date (or the closing date, in the case of the first distribution
date).

                            DISTRIBUTIONS OF INTEREST

      On each distribution date, to the extent of available funds from the
related mortgage pool, each class of certificates will, subject to the
limitations described herein, be entitled to receive accrued and unpaid interest
determined on the basis of the outstanding class principal amount of such class
immediately prior to such distribution date (or class notional amount, in the
case of the Class 1-XA or Class 1-XB Certificates), the applicable certificate
interest rate and the related accrual period.

      On each distribution date, (1) amounts otherwise distributable to the
Class 1-XA Certificates will instead be deposited into a reserve fund and
distributed pro rata to the Class 1-A1 and Class 1-A2 Certificates, to the
extent of any accrued and unpaid interest shortfalls on such class attributable
solely to basis risk and (2) amounts otherwise distributable to the Class 1-XB
Certificates will instead be deposited in a reserve fund and distributed
sequentially to the Class 1-B1 and Class 1-B2 Certificates, in that order, to
the extent of any accrued and unpaid interest shortfalls on such classes
attributable solely to basis risk. The Class 1-XA and Class 1-XB Certificates
will not be reimbursed for any shortfalls resulting from the payment rules
described in this paragraph.

      The accrual period applicable to the LIBOR certificates for a given
distribution date will be the period commencing on the 20th day of the month
immediately preceding the month in which such distribution date occurs (or in
the case of the first distribution date, beginning on the closing date of this
transaction) and ending on the 19th day of the month in which such distribution
date occurs. The accrual period applicable to all other classes of offered
certificates will be the calendar month preceding the month in which the
distribution date occurs. Interest on all classes of certificates for all
accrual periods will be calculated and payable on the basis of a 360-day year
consisting of twelve 30-day months, except that for the first accrual

                                      S-4


period only, interest on the LIBOR certificates will be calculated and payable
on the basis of a 21-day accrual period and a year assumed to consist of 360
days.

      Interest payments will be allocated among certificateholders of a class of
certificates on a pro rata basis.

      We refer you to "Description of the Certificates -- Distributions of
Interest" in this prospectus supplement for more information.

                           DISTRIBUTIONS OF PRINCIPAL

      The amount of principal distributable on the group 1 certificates (other
than the interest-only certificates) and the group 2 certificates on any
distribution date will be determined by (1) formulas that allocate portions of
principal payments received on the pool 1 mortgage loans and the pool 2 mortgage
loans, respectively, among the related classes of certificates and (2) the
amount of funds actually received on the pool 1 mortgage loans and the pool 2
mortgage loans, respectively, and available to make distributions on the related
classes of certificates. Funds actually received on the mortgage loans may
consist of scheduled payments and unscheduled payments resulting from
prepayments by borrowers, liquidation of defaulted mortgage loans or repurchases
of mortgage loans under the circumstances described in this prospectus
supplement.

      Each group of senior certificates will receive principal payments on each
distribution date in an amount equal to the related "Senior Principal
Distribution Amount" based solely on principal collections from the related
mortgage pool for the related due period. Except under the limited circumstances
described in this prospectus supplement, the group 1 subordinate certificates
and the group 2 subordinate certificates will not receive principal
distributions (or subsequent recoveries) from collections on the mortgage loans
until the distribution dates in October 2015 and October 2012, respectively.
Thereafter, provided that certain tests are met, the group 1 subordinate
certificates and the group 2 subordinate certificates will receive principal
collections in an amount equal to the related "Subordinate Principal
Distribution Amount," based solely on collections of principal from the related
mortgage pool for the related due period.

      We refer you to "Description of the Certificates -- Distributions of
Principal" in this prospectus supplement and "Description of the Securities --
Distributions on Securities" in the prospectus for more information.

                        FINAL SCHEDULED DISTRIBUTION DATE

      The final scheduled distribution date for the group 1 certificates is the
distribution date in October 2035, which is the distribution date in the month
following the scheduled maturity date for the latest maturing mortgage loan in
pool 1. The final scheduled distribution date for the group 2 certificates is
the distribution date in April 2035, which is the distribution date in the month
following the scheduled maturity date for the latest maturing mortgage loan in
pool 2.

                OPTIONAL CLEAN-UP REDEMPTION OF THE CERTIFICATES

      On any distribution date on or after the distribution date (the "pool 1
initial clean-up call date") on which the aggregate outstanding principal
balance of the mortgage loans in pool 1 is equal to or less than 10% of the
aggregate principal balance of the pool 1 mortgage loans as of the cutoff date,
subject to satisfaction of the conditions described in the pooling and

                                      S-5


servicing agreement, the master servicer may purchase all of the pool 1 mortgage
loans and apply the proceeds to redeem the group 1 certificates at a price equal
to 100% of the unpaid principal balance of such certificates, plus accrued and
unpaid interest thereon (excluding the amount of any unpaid shortfalls described
at "Description of the Certificates -- Distributions of Interest -- Net WAC
Shortfalls").

      If the master servicer fails to purchase the mortgage loans in pool 1 on
the pool 1 initial clean-up call date, then on the immediately following
distribution date, the related margin for the LIBOR certificates will increase
as described at "Description of the Certificates -- Distributions of Interest"
and "-- Optional Clean-Up Redemption of the Certificates" in this prospectus
supplement, and such increased margin will be in effect on all subsequent
distribution dates.

      On any distribution date on or after the distribution date on which the
aggregate outstanding principal balance of the mortgage loans in pool 2 is less
than 1% of the aggregate principal balance of the pool 2 mortgage loans as of
the cut-off date, subject to satisfaction of the conditions described in the
pooling and servicing agreement, the master servicer may purchase all of the
pool 2 mortgage loans and apply the proceeds to redeem the group 2 certificates
at a price equal to 100% of the unpaid principal balance of such certificates,
plus accrued and unpaid interest thereon (excluding the amount of any unpaid
shortfalls described at "Description of the Certificates -- Distributions of
Interest -- Net WAC Shortfalls").

      There will be no increase in the certificate interest rate of the group 2
certificates due to any exercise, or failure by the master servicer to exercise,
any optional purchase right in connection with the pool 1 mortgage loans or the
pool 2 mortgage loans.

      We refer you to "Description of the Certificates -- Optional Clean-Up
Redemption of the Certificates" in this prospectus supplement for more
information.

                               CREDIT ENHANCEMENT

      The payment structure of this securitization includes subordination and
loss allocation features to enhance the likelihood that holders of more senior
classes of certificates will receive regular distributions of interest and
principal.

      Subordination. The group 1 senior certificates (and the Class 1-XA and
Class 1-XB Certificates for payments of interest) will have a payment priority
over the group 1 subordinate certificates. The Class 1-B1 Certificates will have
a payment priority over the Class 1-B2 and Class 1-B3 Certificates, and the
Class 1-B2 Certificates will have a payment priority over the Class 1-B3
Certificates. Each of the Class 1-B1, Class 1-B2 and Class 1-B3 Certificates
will have a payment priority over the other classes of group 1 subordinate
certificates.

      The group 2 senior certificates will have a payment priority over the
group 2 subordinate certificates. The Class 2-B1 Certificates will have a
payment priority over the Class 2-B2 and Class 2-B3 Certificates, and the Class
2-B2 Certificates will have a payment priority over the Class 2-B3 Certificates.
Each of the Class 2-B1, Class 2-B2 and Class 2-B3 Certificates will have a
payment priority over the other classes of group 2 subordinate certificates.

      Loss Allocation. As described in this prospectus supplement, amounts
representing losses on the mortgage loans

                                      S-6


will be applied to reduce the class principal amount of the class of subordinate
certificates for the related mortgage pool that is still outstanding and has the
lowest payment priority, until the class principal amount of that class has been
reduced to zero. If the applicable subordination provided by the subordinate
certificates is insufficient to absorb losses, then losses realized by the
applicable mortgage pool will be allocated in reduction of the class principal
amount of the related group of senior certificates; provided, however, that
losses that would otherwise reduce the class principal amount of the Class 1-A1
Certificates will first reduce the class principal amount of the Class 1-A2
Certificates until the class principal amount of the Class 1-A2 Certificates has
been reduced to zero; and provided, further, that losses that would otherwise
reduce the class principal amount of the Class 2-A1 Certificates will first
reduce the class principal amount of the Class 2-A2 Certificates until the class
principal amount of the Class 2-A2 Certificates has been reduced to zero.

      -     For example, losses in pool 1 will first be allocated in reduction
            of the class principal amount of the Class 1-B6 Certificates until
            it has been reduced to zero, then to the Class 1-B5 Certificates,
            until the class principal amount of such class has been reduced to
            zero, then to the Class 1-B4 Certificates, until the class principal
            amount of such class has been reduced to zero, then to each class of
            the group 1 subordinate certificates in reverse order of seniority,
            until the class principal amount of each such class has been reduced
            to zero, and then to the group 1 senior certificates, as described
            in this prospectus supplement.

      -     For example, losses in pool 2 will first be allocated in reduction
            of the class principal amount of the Class 2-B6 Certificates until
            it has been reduced to zero, then to the Class 2-B5 Certificates,
            until the class principal amount of such class has been reduced to
            zero, then to the Class 2-B4 Certificates, until the class principal
            amount of such class has been reduced to zero, then to each class of
            the group 2 subordinate certificates in reverse order of seniority,
            until the class principal amount of each such class has been reduced
            to zero, and then to the group 2 senior certificates, as described
            in this prospectus supplement.

      If a loss has been allocated to reduce the principal amount of your
certificate, you will receive no payment in respect of that reduction, except to
the extent of any subsequent recoveries allocable to your certificate. On any
distribution date on which a subsequent recovery is distributed, the class
principal amount of any class of certificates then outstanding to which a
realized loss amount has been applied will be increased, by the amount of such
subsequent recovery as described at "Description of the Certificates --
Distributions of Interest" in this prospectus supplement.

      If the subordination of the related subordinate certificates is
insufficient to absorb losses, then, to the extent described in this prospectus
supplement, the senior certificates relating to the mortgage pool incurring the
realized losses will be

                                      S-7


allocated such losses and may never receive all of their principal payments.

      We refer you to "Risk Factors -- Potential Inadequacy of Credit
Enhancement," "Description of the Certificates -- Priority of Distributions" and
" -- Allocation of Realized Losses" in this prospectus supplement for more
information.

                               THE MORTGAGE LOANS

      Statistical Information. The statistical information on the mortgage loans
presented herein is based on the principal balance of such mortgage loans as of
September 1, 2005 (referred to herein as the "cut-off date"). Such information
does not take into account defaults, delinquencies and prepayments that may have
occurred with respect to the mortgage loans since such date. As a result, the
statistical distribution of the characteristics in the final mortgage pools as
of the closing date will vary from the statistical distribution of such
characteristics as presented in this prospectus supplement, although such
variance will not be material.

      General. As of the cut-off date, the assets of the trust fund consisted of
approximately 541 mortgage loans with an aggregate principal balance of
approximately $329,050,841. The mortgage loans consist primarily of adjustable
rate, conventional, fully amortizing, first lien residential mortgage loans, all
of which have an original term to stated maturity of 25 to 30 years.

      Pool 1 Characteristics. As of the cut-off date, pool 1 consisted of
approximately 270 mortgage loans having an aggregate principal balance of
approximately $155,032,375 (or approximately 47.12% of the aggregate cut-off
date balance of the mortgage loans). The mortgage rates of approximately 59.54%,
39.30% and 1.16% of the pool 1 mortgage loans adjust based on the one-month
LIBOR, the six-month LIBOR index and the prime rate, respectively, and all such
mortgage loans have original terms to maturity of either 25 or 30 years.

      All of the pool 1 mortgage loans provide for payments of interest at the
related mortgage rate, but no payments of principal, for a period of five years
(in the case of approximately 0.04% of the pool 1 mortgage loans) or ten years
(in the case of approximately 99.96% of the pool 1 mortgage loans), in each case
following origination of such mortgage loan. Following such five- or ten-year
period, the monthly payment with respect to each such pool 1 mortgage loan will
be increased to an amount sufficient to amortize the principal balance of such
mortgage loan over its remaining term, and to pay interest at the related
mortgage rate. Approximately $24,141,334 (or approximately 15.57% of the
aggregate cut-off date balance of the pool 1 mortgage loans) are seasoned
mortgage loans with respect to which the interest-only period has expired.

      Pool 2 Characteristics. As of the cut-off date, pool 2 consisted of
approximately 271 mortgage loans having an aggregate principal balance of
approximately $174,018,466 (or approximately 52.88% of the aggregate cut-off
date balance of the mortgage loans). All of the mortgage loans in pool 2 provide
for a fixed mortgage rate during an initial period of approximately five years
from the date of origination and thereafter provide for adjustments to that
mortgage rate on an annual basis based on the one-year CMT index, as described
under "Description of the Mortgage Pools -- The Indices" in this prospectus
supplement. All such mortgage loans have original terms to maturity of 30

                                      S-8


years. Some of the pool 2 mortgage loans were made in connection with the
relocation of employees of various corporate employers. Some of these corporate
employers participate in Wells Fargo Bank, N.A.'s relocation program. All of the
mortgage loans are relationship ARMs, as described in this prospectus
supplement, which have mortgage rates during the fixed-rate period which are
0.125% to 0.500% per annum lower than the rates generally applicable to
comparable loans made to mortgagors who do not have a banking relationship with
Wells Fargo Bank, N.A.

      Approximately 60.75% of the pool 2 mortgage loans provide for payments of
interest at the related mortgage rate, but no payments of principal, for a
period of five years following origination. Following such five-year period, the
monthly payment with respect to each such pool 2 mortgage loan will be increased
to an amount sufficient to amortize the principal balance of such mortgage loan
over its remaining term and to pay interest at the related mortgage rate.

      We refer you to "Description of the Mortgage Pools" in this prospectus
supplement for more information.

      Summary Statistical Data. The following table summarizes the
characteristics of the mortgage loans in the aggregate and by pool as of the
cut-off date. More complete tabular information concerning the statistical
characteristics of the mortgage loans in the aggregate and by mortgage pool as
of the cut-off date can be found at "Description of the Mortgage Pools --
Tabular Characteristics of the Mortgage Loans" in this prospectus supplement.

      Additional Collateral Loans. Approximately 11.28% of the pool 1 mortgage
loans, in addition to being secured by real property, are secured by a security
interest in a limited amount of additional collateral owned by the borrower or a
third-party guarantor. Such additional collateral may no longer be required when
the principal balance of such additional collateral mortgage loan is reduced to
a predetermined amount set forth in the related pledge agreement or guaranty
agreement, as applicable, or when the loan-to-value ratio for such additional
collateral mortgage loan is reduced to the applicable loan-to-value ratio for
such additional collateral mortgage loan by virtue of an

                                      S-9


increase in the appraised value of the mortgaged property as determined by
the related servicer.

      We refer you to "Description of the Mortgage Pools -- The Additional
Collateral Loans" for more information.

                         SERVICING OF THE MORTGAGE LOANS

      The master servicer will supervise the performance of each servicer under
the related servicing agreement.

      Under the servicing agreements, the servicers are generally obligated to
make monthly advances of cash (to the extent such advances are deemed
recoverable), which will be included with mortgage principal and interest
collections, in an amount equal to any delinquent monthly payments due on the
mortgage loans on the immediately preceding determination date. The master
servicer will be obligated to make any required advance if a servicer fails in
its obligation to do so, to the extent described in this prospectus supplement.
The master servicer and the servicers will be entitled to reimburse themselves
for any such advances from future payments and collections (including insurance
or liquidation proceeds) with respect to the mortgage loans. However, if the
master servicer or the servicers make advances which are determined to be
nonrecoverable from future payments and collections on the related mortgage
loan, such parties will be entitled to reimbursement for such advances prior to
any distributions to certificateholders.

      The servicers will also make interest payments to compensate in part for
any shortfall in interest payments on the certificates which results from a
mortgagor prepaying a mortgage loan in whole. However, the amount of such
payments will generally not exceed the servicing fees payable to the servicers
for the related due period. If a servicer fails to make a required payment in
respect of such shortfalls, the master servicer will be obligated to reduce a
portion of its master servicing fee to the extent necessary to fund any such
shortfall.

supplement for more detail.

                        FEDERAL INCOME TAX CONSEQUENCES

      For federal income tax purposes, the trustee will elect to treat a portion
of the assets of the trust fund as comprising multiple REMICs. Each of the
offered certificates, other than the Class 1-AR and Class 2-AR Certificates,
will represent ownership of "regular interests" in a REMIC and certain offered
certificates will also represent rights under a notional principal contract held
outside the REMIC. Each of the Class 1-AR and Class 2-AR Certificates will be
designated as the sole class of "residual interests" in a REMIC.

      There are restrictions on the types of investors that are permitted to
purchase the Class 1-AR and Class 2-AR Certificates.

      We refer you to "Federal Income Tax Consequences" in this prospectus
supplement and in the prospectus for more information.

                                  RISK FACTORS

      INVESTORS SHOULD CONSIDER THE FOLLOWING FACTORS IN CONNECTION WITH THE
PURCHASE OF CERTIFICATES. YOU SHOULD ALSO CONSIDER THE RISK FACTORS DESCRIBED IN
THE ACCOMPANYING PROSPECTUS. ALL STATISTICAL INFORMATION REFERRED TO IN THIS
SECTION IS BASED ON THE MORTGAGE POOLS AS CONSTITUTED ON THE CUT-OFF DATE.

PREPAYMENTS ARE UNPREDICTABLE AND AFFECT YIELD

      The rate of principal distributions and yield to maturity on the
certificates will be directly related to the rate of principal payments on the
mortgage loans of the related mortgage pool. For example, the rate of principal
payments on the mortgage loans will be affected by the following:

      -     the amortization schedules of the mortgage loans;

      -     the rate of principal prepayments, including partial prepayments and
            full prepayments resulting from:

                  -     refinancing by borrowers;

                  -     liquidations of defaulted loans by the related servicer;
                        and

                  -     repurchases of mortgage loans by the seller as a result
                        of defective documentation or breaches of
                        representations and warranties.

      The yield to maturity of the group 1 certificates will also be affected,
and the yield to maturity of the group 2 certificates will be affected, by the
master servicer's exercise of the optional clean-up redemption right for pool 1
and pool 2, respectively.

      As of the cut-off date, approximately 95.04% of the mortgage loans in pool
1 and all of the mortgage loans in pool 2 may be prepaid in whole or in part at
any time without payment of a prepayment penalty. The rate of principal payments
on mortgage loans is influenced by a wide variety of economic, geographic,
social and other factors, including general economic conditions, the level of
prevailing interest rates, the availability of alternative financing and
homeowner maturity. For example, if interest rates for similar loans fall below
the interest rates on the mortgage loans, the rate of prepayment would generally
be expected to increase. Conversely, if interest rates on similar loans rise
above the interest rates on the mortgage loans, the rate of prepayment would
generally be expected to decrease. We cannot predict the rate at which borrowers
will repay their mortgage loans. Please consider the following:

      -     if you are purchasing any offered certificate at a discount, your
            yield may be lower than expected if principal payments on the
            related mortgage loans occur at a slower rate than you expected;

      -     if you are purchasing any offered certificate at a premium, your
            yield may be lower than expected if principal payments on the
            related mortgage loans occur at a faster rate than you expected, and
            you could lose your initial investment;

                                      S-12


      -     if the rate of default and the amount of losses on the related
            mortgage loans are higher than you expect, then your yield may be
            lower than you expect;

      -     the earlier a payment of principal occurs, the greater the impact on
            your yield. For example, if you purchase any offered certificate at
            a premium, although the average rate of principal payments is
            consistent with your expectations, if the rate of principal payments
            occurs initially at a rate higher than expected, which would
            adversely impact your yield, a subsequent reduction in the rate of
            principal payments will not offset any adverse yield effect;

      -     the priorities governing payments of scheduled and unscheduled
            principal will have the effect of accelerating the rate of principal
            payments to holders of the classes of senior certificates relative
            to the classes of subordinate certificates; and

      See "-- Special Risks for the Class 1-XA and Class 1-XB Certificates,"
"Yield, Prepayment and Weighted Average Life," "Description of the Mortgage
Pools -- Underwriting Standards" and "Description of the Certificates --
Distributions of Principal" in this prospectus supplement for a description of
the factors that may influence the rate and timing of prepayments on the
mortgage loans.

MORTGAGE LOANS WITH INTEREST-ONLY PAYMENTS AND HIGH BALANCE LOANS

      All of the group 1 mortgage loans and approximately 60.75% of the group 2
mortgage loans provide for payment of interest at the related mortgage rate, but
no payment of principal, for a period of five or ten years following the
origination of the related mortgage loan. Following the applicable interest-only
period, the monthly payment with respect to each mortgage loan will be increased
to an amount sufficient to amortize the principal balance of such mortgage loan
over its remaining term, and to pay interest at the related mortgage rate. The
required payment of principal will increase the burden on the mortgagor and may
increase the risk of default under the related mortgage loan. Higher scheduled
monthly payments may induce the related mortgagors to refinance their Mortgage
Loans, which would result in higher prepayments.

      Such interest-only mortgage loans will, absent other considerations,
result in longer weighted average lives of the certificates when compared to
certificates backed by fully amortizing mortgage loans without interest-only
periods. If you purchase a certificate at a discount, you should consider that
the extension of its weighted average life could result in a lower yield than
would be the case if such mortgage loans provided for payment of principal and
interest on every distribution date. In addition, a borrower may view the
absence of any obligation to make a payment of principal during the first five
or ten years of the term of the mortgage loan as a disincentive to prepayment.
In addition, approximately 15.57% of the mortgage loans in pool 1 are seasoned
mortgage loans with respect to which the interest-only period has expired, so
these loans may be more susceptible to prepayment due to refinancing than less
seasoned loans.

      In the case of the mortgage loans in pool 2, the increase in the
mortgagor's monthly payment attributable to principal will occur when the
mortgagor's monthly interest payment will no longer have the benefit of a
reduced rate due to the fact that the mortgage loan is a

                                      S-13


relationship ARM and may coincide with an increase in the mortgage rate on the
related first adjustment date. If a recalculated monthly payment as described
above is substantially higher than a borrower's previous interest-only monthly
payment, that loan may also be subject to an increased risk of delinquency and
loss.

      See "Description of the Mortgage Pools" in this prospectus supplement.

      As of the cut-off date, the principal balances of approximately 36 of the
mortgage loans in pool 1, representing approximately 46.17% of the pool 1
cut-off date balance, were in excess of $1,000,000, and approximately 11 of the
mortgage loans in pool 2, representing approximately 9.67% of the pool 2 cut-off
date balance, were in excess of $1,000,000. You should consider the risk that
the loss and delinquency experience on these high balance loans may have a
disproportionate effect on the related mortgage pool.

YOUR YIELD MAY BE AFFECTED BY CHANGES IN INTEREST RATES

      No prediction can be made as to future levels of one-month LIBOR (the
applicable index in determining the certificate interest rate for the LIBOR
certificates and the mortgage rate for approximately 59.54% of the mortgage
loans in pool 1), six-month LIBOR (the applicable index in determining the
mortgage rates for approximately 39.30% of the mortgage loans in pool 1), the
prime rate (the applicable index in determining the mortgage rates for
approximately 1.16% of the mortgage loans in pool 1) or one-year CMT (the
applicable index in determining the mortgage rates for all of the mortgage loans
in pool 2 after expiration of the five-year fixed rate period), or as to the
timing of any changes therein, each of which will directly affect the yields of
the related certificates.

      In addition, although the interest rate on each pool 1 mortgage loan
adjusts in accordance with fluctuations in the value of either one-month LIBOR,
six-month LIBOR or the prime rate, and after expiration of the initial
fixed-rate period, the interest rate on each pool 2 mortgage loan adjusts in
accordance with fluctuations in the value of one-year CMT, the mortgage loans
may also have periodic and maximum limitations on adjustments to their mortgage
rates. As a result of such limitations, increases in the value of the related
index will not necessarily be reflected in corresponding increases in the value
of the weighted average net mortgage rates of the related mortgage loans.

      As described in this prospectus supplement, the interest rates of the
LIBOR certificates on each distribution date are capped. If the weighted average
net mortgage rate of the mortgage loans in pool 1 is less than both (i)
one-month LIBOR plus the related margin for such distribution date and (ii)
11.50%, then the interest rate of the LIBOR certificates will be the weighted
average net mortgage rate of the mortgage loans in pool 1 for such date. In no
event will the interest rates of the LIBOR certificates exceed 11.50%.

      The prepayment of mortgage loans with relatively higher net mortgage rates
may also result in a lower weighted average net mortgage rate and will reduce
the certificate interest rate of the Class 1-XA and Class 1-XB Certificates and
the group 2 certificates. In addition, if on any distribution date the interest
rate of the LIBOR certificates is limited by the application of the related
weighted average net mortgage rate cap during the related interest accrual
period, the value of those certificates may be temporarily or permanently
reduced.

                                      S-14


      Investors in the group 1 certificates should be aware that the mortgage
rates on approximately 39.30% of the mortgage loans in pool 1 are generally
adjustable semi-annually based on the six-month LIBOR index or adjust based on a
different index, which may respond to economic and market factors that differ
from those that affect the one-month LIBOR index. Consequently, the applicable
net funds cap on the interest rates on the LIBOR certificates (which will be
reset monthly before the beginning of each accrual period) may prevent increases
in the certificate interest rates of those certificates for extended periods in
a rising interest rate environment.

      Investors in the group 2 certificates should be aware that the mortgage
rates on all of the mortgage loans in pool 2 adjust annually based on the
one-year CMT index after the initial fixed-rate period, in a rising interest
rate environment, the weighted average net mortgage rate of the pool 2 mortgage
loans, and the certificate interest rate of the group 2 certificates, will not
increase as rapidly as they would if the pool 2 mortgage loans adjusted more
frequently. The certificate interest rate of the group 2 certificates may
decrease, and decrease significantly, after the mortgage rates on the pool 2
mortgage loans begin to adjust, as a result of, and among other factors, the
dates of adjustment, the gross margins and changes in the index. The mortgage
rates on the pool 2 mortgage loans will not all begin to adjust on the same
date. Therefore, the mortgage rates of some of the pool 2 mortgage loans may
still be in their fixed-rate period, while the mortgage rates of other pool 2
mortgage loans may have begun to adjust. Moreover, although each pool 2 mortgage
loan has a maximum mortgage rate, none of the pool 2 mortgage loans has a
specified minimum rate. Accordingly, the minimum mortgage rate to which the pool
2 mortgage loans may adjust will be the gross margin. In addition, if, despite
increases in one-year CMT, the mortgage rate on any pool 2 mortgage loan cannot
be increased due to a maximum mortgage rate limitation or a periodic cap, the
yield on the group 2 certificates may be adversely affected. Further, because
the certificate interest rates on the group 2 certificates will be based on the
weighted average net mortgage rate of the pool 2 mortgage loans,
disproportionate principal payments on pool 2 mortgage loans having net mortgage
rates higher or lower than the current certificate interest rate of the group 2
certificates will affect the certificate interest rates of the group 2
certificates for future periods and the yields on the group 2 certificates.

      To the extent that the related weighted average net mortgage rate of the
related mortgage loans limits the amount of interest paid on the LIBOR
certificates, the difference between the related weighted average net mortgage
rate and the interest rate of those classes of certificates, calculated without
giving effect to such limitation, will create a shortfall that will carry
forward with interest thereon, as described herein. However, any such resulting
shortfall will only be paid to the extent there are amounts on deposit in the
reserve fund funded from (i) in the case of the Class 1-A1 and Class 1-A2
Certificates, amounts otherwise payable to the Class 1-XA certificates and (ii)
in the case of the Class 1-B1 and Class 1-B2 Certificates, amounts otherwise
payable on the Class 1-XB Certificates. Accordingly, these shortfalls may remain
unpaid on any optional clean-up redemption for pool 1 or on the final
distribution date.

      See "Description of the Certificates -- Distributions of Interest" in this
prospectus supplement.

                                      S-15


NO CROSS-COLLATERALIZATION BETWEEN POOL 1 AND POOL 2

      Interest and principal on the group 1 certificates other than the
interest-only certificates and interest on the Class 1-XA and Class 1-XB
Certificates will be payable solely from amounts collected on the pool 1
mortgage loans, and interest and principal on the group 2 certificates will be
payable solely from amounts collected on the pool 2 mortgage loans. Pool 1 and
pool 2 will not be "cross-collateralized"-- i.e., interest and principal
received on mortgage loans from each mortgage pool will not be available for
distribution to the unrelated groups of certificates under any circumstances. As
a result, a disproportionately high rate of delinquencies or defaults in one
pool may result in shortfalls or losses affecting the related subordinate
certificates at the same time amounts from the other mortgage pool are being
distributed in respect of certificates relating to that pool with lower
seniority. For example, on any distribution date, the class principal amount of
the Class 1-B1 Certificates may be reduced because of excessive losses on the
pool 1 mortgage loans, even though the Class 2-B3 Certificates relating to pool
2 are still outstanding and continue to receive distributions from pool 2.
Moreover, in the case of extremely high losses experienced by a pool, it is
possible that the related senior certificates may not be receiving distributions
and may be allocated losses even though the subordinate certificates relating to
the other pool are still outstanding and receiving distributions.

SPECIAL RISKS FOR THE CLASS 1-XA AND CLASS 1-XB CERTIFICATES

      The Class 1-XA and Class 1-XB Certificates are interest-only certificates.
These certificates have yields to maturity (or early termination)--the yield
that you will receive if you hold a certificate until it has been paid in full
- --that are highly sensitive to prepayments on the pool 1 mortgage loans. In
addition, the interest rate on the Class 1-XA Certificates will be reduced if
the weighed average certificate interest rate on the group 1 senior certificates
(other than the Class 1-XA or Class 1-XB Certificates) approaches the pool 1 net
funds cap or will be reduced to zero if the weighted average certificate
interest rate on the group 1 senior certificates (other than the Class 1-XA or
Class 1-XB Certificates) equals or exceeds the pool 1 net funds cap.

      The interest rate on the Class 1-XB Certificates will be reduced if the
weighed average certificate interest rate on the Class 1-B1 and Class 1-B2
Certificates approaches the pool 1 net funds cap or will be reduced to zero if
the weighted average certificate interest rate on the Class 1-B1 and Class 1-B2
Certificates equals or exceeds the pool 1 net funds cap.

      In addition, as described in this prospectus supplement, the amount of
interest that would otherwise be distributable to the holders of the Class 1-XA
and Class 1-XB Certificates, based on the applicable interest rate may be
reduced by the amount, if any, that is necessary to fund payment of any Net WAC
Shortfalls to the holders of the Class 1-A1 and Class 1-A2 Certificates, in the
case of the Class 1-XA Certificates, and to the holders of the Class 1-B1 and
Class 1-B2 Certificates, in the case of the Class 1-XB Certificates. The holders
of the Class 1-XA and Class 1-XB Certificates will not be reimbursed for any
such amounts.

      Interest will accrue on the Class 1-XA Certificates on their class
notional amount, which will decline as principal is distributed to the Class
1-A1 and Class 1-A2 Certificates; and interest will accrue on the Class 1-XB
Certificates on their class notional amount, which will decline as principal is
distributed to the Class 1-B1 and Class 1-B2 Certificates. Prospective
purchasers of

                                      S-16


the Class 1-XA and Class 1-XB Certificates should carefully consider the risk
that a rapid rate of principal payments on the pool 1 mortgage loans could
result in the failure of such purchasers to recover their initial investments.

      See "Yield, Prepayment and Weighted Average Life--Sensitivity of the
Class 1-XA and Class 1-XB Certificates" in this prospectus supplement.

PREPAYMENTS DUE TO SERVICER PROGRAMS

      The rate of principal prepayments may also be influenced by programs
offered by mortgage loan originators, servicers and brokers (including the
Servicers and their affiliates). In particular, a borrower whose mortgage loan
is serviced by Wells Fargo Bank, N.A. may be eligible for such Servicer's
retention program. If a mortgage loan in pool 2 satisfies the eligibility
criteria of Wells Fargo Bank, N.A.'s retention program, the related borrower may
be offered the opportunity to refinance such loan at the current market interest
rate without the application of significant borrower credit or property
underwriting standards. Investors in the certificates, particularly the group 2
certificates, should consider that these types of programs may significantly
increase the rate of principal prepayments on the related mortgage loans.

      See "Description of the Mortgage Pools--Y Underwriting Standards--Y Wells
Fargo" in this prospectus supplement.

DELINQUENCIES DUE TO SERVICING TRANSFER

      Mortgage loans serviced by one or more of the initial servicers may be
transferred in the future to new servicers in accordance with the provisions of
the pooling and servicing agreement and the related servicing agreement.

      Mortgage loans subject to servicing transfers may experience increased
delays in payment until all of the borrowers are informed of the transfer and
the related servicing mortgage files and records and all other relevant data has
been obtained by the new servicer.

      See "The Servicers" and "Servicing of the Mortgage Loans" in this
prospectus supplement.

LIMITED RECOURSE

      The only source of cash available to make interest and principal
distributions on the certificates will be the assets of the trust fund, as
allocated among the related certificates, as described in this prospectus
supplement. Neither the certificates nor the assets of the trust fund will be
guaranteed by the depositor, the seller, the master servicer, the securities
administrator, the servicers, the trustee or any of their respective affiliates
or insured by any governmental agency. Consequently, if collections on the
related mortgage loans are insufficient to make all payments required on the
certificates and the protection against losses provided by subordination is
exhausted, you may incur a loss on your investment.

                                      S-17


POTENTIAL INADEQUACY OF CREDIT ENHANCEMENT

      The certificates are not insured by any financial guaranty insurance
policy. The subordination and loss allocation features described in this
prospectus supplement are intended to enhance the likelihood that holders of
more senior classes of certificates will receive regular payments of interest
and principal, but are limited in nature and may be insufficient to cover all
losses on the related mortgage loans. If the applicable subordination is
insufficient to absorb losses, then certificateholders will likely incur losses
and may never receive all of their principal payments.

certificate:

      -     if you buy a Class 1-B3 Certificate and losses on the pool 1
            mortgage loans exceed the aggregate class principal amounts of the
            Class 1-B6, Class 1-B5 and Class 1-B4 Certificates, the principal
            amount of your certificate will be reduced proportionately with the
            principal amounts of the other Class 1-B3 Certificates by the amount
            of those losses;

      -     if you buy a Class 1-B2 Certificate and losses on the pool 1
            mortgage loan exceed the aggregate class principal amount of the
            Class 1-B6, Class 1-B5, Class 1-B4 and Class 1-B3 Certificates, the
            principal amount of your certificate will be reduced proportionately
            with the principal amounts of the other Class 1-B2 Certificates by
            the amount of that excess;

      -     if you buy a Class 1-B1 Certificate and losses on the pool 1
            mortgage loan exceed the aggregate class principal amount of the
            Class 1-B6, Class 1-B5, Class 1-B4, Class 1-B3 and Class 1-B2
            Certificates, the principal amount of your certificate will be
            reduced proportionately with the principal amounts of the other
            Class 1-B1 Certificates by the amount of that excess; and

      -     if you buy a group 1 senior certificate and losses on the pool 1
            mortgage loan exceed the aggregate class principal amount of the
            group 1 subordinate certificates, the principal amount of your class
            will be reduced pro rata with the other classes of group 1 senior
            certificates, and the principal amount of your certificate will be
            reduced proportionately with the principal amounts of the other
            group 1 certificates of your class, in each case by the amount of
            that excess; provided, however, that losses that would otherwise
            reduce the principal amount of the Class 1-A1 Certificates will
            first reduce the principal amount of the Class 1-A2 Certificates
            until the principal amount of the Class 1-A2 Certificates has been
            reduced to zero.

      Prospective investors in the Class 1-XA or Class 1-XB Certificates should
consider the risks described under "-- Special Risks for the Class 1-XA and
Class 1-XB Certificates" below.

      Pool 2. You should consider the following if you invest in a group 2
certificate:

      -     if you buy a Class 2-B3 Certificate and losses on the pool 2
            mortgage loans exceed the aggregate class principal amounts of the
            Class 2-B6, Class 2-B5 and Class 2-B4 Certificates, the principal
            amount of your certificate will be reduced proportionately

                                      S-18


            with the principal amounts of the other Class 2-B3 Certificates by
            the amount of those losses;

      -     if you buy a Class 2-B2 Certificate and losses on the pool 2
            mortgage loan exceed the aggregate class principal amount of the
            Class 2-B6, Class 2-B5, Class 2-B4 and Class 2-B3 Certificates, the
            principal amount of your certificate will be reduced proportionately
            with the principal amounts of the other Class 2-B2 Certificates by
            the amount of that excess;

      -     if you buy a Class 2-B1 Certificate and losses on the pool 2
            mortgage loan exceed the aggregate class principal amount of the
            Class 2-B6, Class 2-B5, Class 2-B4, Class 2-B3 and Class 2-B2
            Certificates, the principal amount of your certificate will be
            reduced proportionately with the principal amounts of the other
            Class 2-B1 Certificates by the amount of that excess; and

      -     if you buy a group 2 senior certificate and losses on the pool 2
            mortgage loan exceed the aggregate class principal amount of the
            group 2 subordinate certificates, the principal amount of your class
            will be reduced pro rata with the other classes of group 2 senior
            certificates, and the principal amount of your certificate will be
            reduced proportionately with the principal amounts of the other
            group 2 certificates of your class, in each case by the amount of
            that excess; provided, however, that losses that would otherwise
            reduce the principal amount of the Class 2-A1 Certificates will
            first reduce the principal amount of the Class 2-A2 Certificates
            until the principal amount of the Class 2-A2 Certificates has been
            reduced to zero.

      If a loss has been allocated to reduce the principal amount of your
certificate, you will receive no payment in respect of that reduction, except to
the extent of any subsequent recoveries allocable to your certificate. It is
generally not anticipated that any such amounts will be recovered, or that any
distributions in respect of subsequent recoveries will be made to the
subordinate certificates prior to the distribution date in October 2015, in the
case of the group 1 subordinate certificates, or the distribution date in
October 2012, in the case of the group 2 subordinate certificates. No interest
will be paid to certificateholders on the amount by which the principal amount
of their certificates was reduced due to application of realized losses.

      See "Description of the Certificates -- Priority of Distributions" and
"--Allocation of Realized Losses" in this prospectus supplement.

CASH FLOW CONSIDERATIONS AND RISKS

      The related mortgage loans, the related mortgaged property and additional
collateral and other assets of the trust are the sole source of payments on the
certificates. Even if the mortgaged properties provide adequate security for the
mortgage loans, you could encounter substantial delays in connection with the
liquidation of mortgage loans that are delinquent. This could result in
shortfalls in payments on the related certificates if the credit enhancement
provided by subordination is insufficient. Further, liquidation expenses, such
as legal fees, real estate taxes and maintenance and preservation expenses, will
reduce the security for the related mortgage loans and could thereby reduce the
proceeds payable to certificateholders. If any of the mortgaged properties and
additional collateral fail to provide adequate security for the related

                                      S-19


mortgage loans, certificateholders could experience a loss if the credit
enhancement created by the subordination has been exhausted.

CONCENTRATION OF MORTGAGE LOANS COULD ADVERSELY AFFECT YOUR INVESTMENT

      Approximately 24.84% and 12.76% of the mortgage loans included in pool 1
are secured by mortgaged properties located in California and Florida,
respectively; and approximately 86.93% of the mortgage loans included in pool 2
are secured by mortgaged properties located in California. Consequently, losses
and prepayments on the mortgage loans in a particular pool and the resultant
payments on the related certificates may be affected significantly by changes in
the housing markets and the regional economies in areas in these states and by
the occurrence of natural disasters, such as earthquakes, hurricanes, tornadoes,
tidal waves, mud slides, fires and floods in areas in these states.

      Recently Hurricane Katrina caused extensive damages to parts of Alabama,
Louisiana and Mississippi, and Hurricane Rita caused extensive damage in
affected areas, including parts of Louisiana and Texas. Parts of Florida were
also affected by Hurricane Katrina. There are no mortgaged properties located in
the areas of Alabama, Louisiana, Mississippi or Texas which the Federal
Emergency Management Agency has declared to be Individual Assistance designated
areas. However, approximately 20.73% of the mortgage loans in pool 1 are secured
by mortgaged properties located in other parts of Alabama, Louisiana,
Mississippi and Texas and in Florida. These properties may have been damaged by
Hurricane Katrina or Hurricane Rita, although the damage in these areas may be
less severe. We do not know how many mortgaged properties in Louisiana or Texas
have been affected by Hurricane Rita. Extensive damage to, or total destruction
of, mortgaged properties in affected areas may result in (1) an increase in
delinquencies, defaults and losses on the related mortgage loans or (2) the
receipt of insurance payments in respect of the mortgaged properties, which
payments will have the same effect on certificateholders as prepayment in full
of the related mortgage loans. In addition, weakened economic conditions in and
around the affected areas may adversely affect the ability of borrowers to repay
their mortgage loans. No assurance can be given as to the rate of delinquencies,
defaults or losses on, or prepayments of, any mortgage loans secured by
mortgaged properties located in areas affected by Hurricane Katrina or Hurricane
Rita.

      The seller will be obligated to repurchase any mortgage loan if the
related property incurred material damage prior to the closing date and this
damage had a material adverse effect on the interest of certificateholders in
the mortgage loan. Any such repurchase will result in principal prepayment, and
accordingly, the yield to maturity of any certificate acquired at a premium may
be substantially reduced. Investors should consider that the class notional
balance of the Class 1-XA and Class 1-XB Certificates may be substantially
reduced as a result of any such prepayments on the pool 1 mortgage loans.

      See "-- Special Risks for the Class 1-XA and Class 1-XB Certificates,"
"Description of the Mortgage Pools -- Tabular Characteristics of the Mortgage
Loans" and "Yield, Prepayment and Weighted Average Life" in this prospectus
supplement.

                                      S-20


MILITARY ACTION AND TERRORIST ATTACKS

      The effects that military action by U.S. forces in Iraq or other regions
and terrorist attacks in the United States or other incidents and related
military action may have on the performance of the mortgage loans or on the
values of mortgaged properties cannot be determined at this time. Investors
should consider the possible effects on delinquency, default and prepayment
experience of the mortgage loans. Federal agencies and non-government lenders
may defer, reduce or forgive payments and delay foreclosure proceedings in
respect of loans to borrowers affected in some way by recent and possible future
events. In addition, activation of a substantial number of U.S. military
reservists or members of the National Guard may significantly increase the
proportion of mortgage loans whose mortgage rates are reduced by application of
the Servicemembers Civil Relief Act, as amended, or similar state or local laws,
and neither the master servicer nor the servicers will be required to advance
for any interest shortfall caused by any such reduction. Shortfalls in interest
may result from the application of the Servicemembers Civil Relief Act or
similar state or local laws. Interest payable to senior and subordinate
certificateholders will be reduced on a pro rata basis by any reductions in the
amount of interest collectible as a result of application of the Servicemembers
Civil Relief Act or similar state or local laws.

ABILITY TO RESELL SECURITIES MAY BE LIMITED

      There is currently no market for any of the certificates and the
underwriters are not required to assist investors in resales of the offered
certificates, although they may do so. We cannot assure you that a secondary
market will develop, or if it does develop, that it will continue to exist for
the term of the certificates. Consequently, you may not be able to sell your
certificates readily or at prices that will enable you to realize your desired
yield. The market values of the certificates are likely to fluctuate; these
fluctuations may be significant and could result in significant losses to you.

      The secondary market for mortgage pass-through certificates has
experienced periods of illiquidity and can be expected to do so in the future.
Illiquidity can have a severe adverse effect on the prices of certificates that
are especially sensitive to prepayment, credit or interest rate risk, or that
have been structured to meet the investment requirements of limited categories
of investors.

CONSEQUENCES OF OWNING BOOK-ENTRY SECURITIES

      LIMIT ON LIQUIDITY OF SECURITIES. Issuance of the certificates in
book-entry form may reduce their liquidity in the secondary trading market
because investors may be unwilling to purchase certificates for which they
cannot obtain physical certificates.

      LIMIT ON ABILITY TO TRANSFER OR PLEDGE. Since transactions in the
book-entry certificates can be effected only though the DTC, participating
organizations, indirect participants and certain banks, your ability to transfer
or pledge a book-entry certificate to persons or entities that do not
participate in the DTC system or otherwise to take actions in respect of such
certificates, may be limited due to lack of physical certificates.

      DELAYS IN PAYMENTS. You may experience some delay in the receipt of
payments on book-entry certificates because the payment will be forwarded by the
Securities Administrator,

                                      S-21


on behalf of the Trustee to DTC, for DTC to credit the accounts of its
participants which will thereafter credit them to your account either directly
or indirectly through indirect participants, as applicable.

DELINQUENCIES MAY ADVERSELY AFFECT INVESTMENT

      The mortgage loans were either originated or acquired in accordance,
generally, with the underwriting guidelines described in this prospectus
supplement. We cannot assure you that the values of the mortgaged properties
have remained or will remain at levels in effect on the date of origination of
the related mortgage loans.

YOU COULD BE ADVERSELY AFFECTED BY VIOLATIONS OF CONSUMER PROTECTION LAWS

      Applicable state laws generally regulate interest rates and other charges
and require certain disclosures. In addition, state and federal consumer
protection laws, unfair and deceptive practices acts and debt collection
practices acts may apply to the origination or collection of the mortgage loans.
Depending on the provisions of the applicable law, violations of these laws may
limit the ability of the servicers to collect all or part of the principal of or
interest on the mortgage loans, may entitle the borrower to a refund of related
amounts previously paid and, in addition, could subject the master servicer or
the related servicer to damages and administrative enforcement.

      The Federal Home Ownership and Equity Protection Act of 1994, commonly
known as HOEPA, prohibits inclusion of some provisions in mortgage loans that
have mortgage rates or origination costs in excess of prescribed levels, and
requires that borrowers be given certain disclosures prior to the consummation
of such mortgage loans. Some states have enacted, or may enact, similar laws or
regulations, which in some case impose restrictions and requirements greater
than those in HOEPA. Under the anti-predatory lending laws of some states, the
origination of a mortgage loan must satisfy a net tangible benefits test with
respect to the related borrower. This test may be highly subjective and open to
interpretation. As a result, a court may determine that a mortgage loan does not
meet the test, even if the originator reasonably believed the test was
satisfied. Failure to comply with these laws, to the extent applicable to any of
the mortgage loans, could subject the trust as an assignee of the mortgage
loans, to monetary penalties and could result in the borrowers rescinding such
mortgage loans against the trust. Lawsuits have been brought in various states
making claims against assignees of high cost loans for violations of state law.
Named defendants in these cases have included numerous participants within the
secondary mortgage market, including some securitization trusts.

      The seller will represent that the mortgage pool does not include any
mortgage loans subject to HOEPA, that are "high cost" loans within the meaning
of any applicable local, state or federal anti-predatory or anti-abusive lending
laws. However, if it is determined that the trust fund includes loans subject to
HOEPA or such other applicable state laws, the seller will be required to
repurchase the affected loans and to pay any liabilities incurred by the trust
fund due to any violations of these laws. If the loans are found to have been
originated in violation of predatory lending laws, certificateholders could
incur losses.

      See "Certain Legal Aspects of the Loans" in the accompanying prospectus.

                                      S-22


BANKRUPTCY AND INSOLVENCY RISKS

      It is believed that the transfer of the mortgage loans from the seller to
the depositor and from the depositor to the trust will each be treated as a sale
rather than a secured financing for purposes of state law. Counsel for the
seller and the depositor will render an opinion on the closing date that in the
event of the bankruptcy of either the seller or the depositor, the mortgage
loans and other assets of the trust fund would not be considered part of the
seller's or depositor's bankruptcy estates and, thus, would not be available to
their creditors. On the other hand, a bankruptcy trustee or one of the creditors
of the seller or the depositor might challenge this conclusion and argue that
the transfer of the mortgage loans should be characterized as a pledge of assets
in a secured borrowing rather than as a sale. Such an attempt, even if
unsuccessful, might result in delays in distributions on the certificates.

                        DESCRIPTION OF THE MORTGAGE POOLS

GENERAL

      The following is a summary description of the Mortgage Loans in the
Mortgage Pools as of September 1, 2005 (the "Cut-off Date"). The information
presented herein does not take into account any Mortgage Loans that have or may
prepay in full or have been or may be removed because of incomplete
documentation or otherwise for the period from the Cut-off Date to the Closing
Date, or other Mortgage Loans that may be substituted therefor. Prior to the
issuance of the Certificates, Mortgage Loans will be removed from one or more
Mortgage Pools if the Depositor deems such removal necessary or appropriate. A
limited number of other mortgage loans may be included in the Mortgage Pools
prior to the issuance of the Certificates. As a result, the information
regarding the Mortgage Loans may vary from comparable information based upon the
actual composition of the Mortgage Pools as of the Closing Date, although such
variance will not be material.

      Whenever reference is made herein to a percentage of some or all of the
Mortgage Loans or some or all of a Mortgage Pool, such percentage is determined
on the basis of the Stated Principal Balance of the Mortgage Loans in the
aggregate or of a particular Mortgage Pool as of the Cut-off Date.

THE MORTGAGE LOANS

      At the Cut-off Date, the assets of the Trust Fund consisted of two pools
("Pool 1" and "Pool 2", respectively, and each, a "Mortgage Pool") having, in
the aggregate, approximately 541 conventional, adjustable rate mortgage loans
(the "Mortgage Loans") secured by first liens on one-to-four family residential
properties (each, a "Mortgaged Property") with original terms to maturity of 25
to 30 years, having an aggregate Stated Principal Balance as of the Cut-off Date
of approximately $329,050,841 (the "Aggregate Cut-off Date Balance"). As
described herein at "Description of the Certificates -- General," the Mortgage
Loans have been segregated into Pool 1 and Pool 2 for the purpose of allocating
distributions between the Group 1 Certificates and the Group 2 Certificates.
Each Mortgage Pool has the characteristics described below.

                                      S-23



      Pool 1 consists of approximately 270 Mortgage Loans (the "Pool 1 Mortgage
Loans") having a Cut-off Date balance of approximately $155,032,375
(approximately 47.12% of the Aggregate Cut-off Date Balance). Approximately
59.54% and 39.30% and 1.16% of the Pool 1 Mortgage Loans are One-Month LIBOR,
Six-Month LIBOR and the Prime Rate indexed Mortgage Loans, respectively (see "--
The Indices" below), and all of such loans have original terms to maturity of
either 25 or 30 years. All of the Pool 1 Mortgage Loans provide for payment of
interest at the related Mortgage Rate, but no payment of principal, for a period
of five years (in the case of approximately 0.04% of the Pool 1 Mortgage Loans)
or ten years (in the case of approximately 99.96% of the Pool 1 Mortgage Loans),
in each case following the origination of the related Mortgage Loan. Following
such five- or ten-year interest-only period, the Scheduled Payment with respect
to each such Pool 1 Mortgage Loan will be adjusted on each adjustment date to an
amount sufficient to amortize the principal balance of such Mortgage Loan over
its remaining term, and to pay interest at the related Mortgage Rate.
Approximately 15.57% of the Pool 1 Mortgage Loans are seasoned mortgage loans
with respect to which the interest-only period has expired.

      Approximately 59.54% of the Pool 1 Mortgage Loans are "One-Month LIBOR
Loans", having Mortgage Rates that adjust monthly in accordance with One-Month
LIBOR. As of the Cut-off Date, with respect to those Pool 1 Mortgage Loans that
are One-Month LIBOR Loans, the weighted average Mortgage Rate is approximately
4.990% per annum, the weighted average Servicing Fee Rate is approximately
0.376% per annum, the weighted average margin is approximately 1.590% per annum,
the weighted average remaining term to maturity is approximately 307 months, and
the weighted average interest only remaining term is approximately 116 months.

      Approximately 39.30% of the Pool 1 Mortgage Loans are "Six-Month LIBOR
Loans", having Mortgage Rates that adjust every six months in accordance with
Six-Month LIBOR. As of the Cut-off Date, with respect to those Pool 1 Mortgage
Loans that are Six-Month LIBOR Loans, the weighted average Mortgage Rate is
approximately 4.856% per annum, the weighted average Servicing Fee Rate is
approximately 0.341% per annum, the weighted average margin is approximately
1.685% per annum, the weighted average remaining term to maturity is
approximately 259 months, and the weighted average interest only remaining term
is approximately 73 months.

      Approximately 1.16% of the Pool 1 Mortgage Loans have Mortgage Rates that
adjust semi-annually in accordance with the Prime Rate.

      The Mortgage Rates on approximately 11.88% of the Pool 1 Mortgage Loans
may not increase or decrease on any interest rate adjustment date by more than a
specified percentage per annum (the "Periodic Cap"). As of the Cut-off Date, the
weighted average Periodic Cap of the Pool 1 Mortgage Loans with Periodic Caps is
approximately 3.000% per annum. The Pool 1 Mortgage Loans are also subject to
maximum Mortgage Rates, at the applicable per annum rate (the "Maximum Mortgage
Rate") specified in the related Mortgage Note.

      The Pool 1 Mortgage Loans were originated from December 1992 through
August 2005. No more than approximately 3.68% of the Pool 1 Mortgage Loans are
secured by Mortgaged Properties located in any one zip code area. The latest
stated maturity date of any Pool 1 Mortgage Loan is September 2035.

                                      S-24


      Approximately 62.38%, 15.57% and 13.65% of the Pool 1 Mortgage Loans were
originated by Morgan Stanley Credit Corporation (formerly Morgan Stanley Dean
Witter Credit Corporation) ("MSCC"), Merrill Lynch Mortgage Corporation ("MLCC")
and Countrywide Home Loans, Inc. ("Countrywide"), respectively.

      Pool 2 consists of approximately 271 Mortgage Loans (the "Pool 2 Mortgage
Loans"), having a Cut-off Date balance of approximately $174,018,466
(approximately 52.88% of the Aggregate Cut-off Date Balance). All of the Pool 2
Mortgage Loans provide for a fixed Mortgage rate for approximately five years
after the date of origination and for adjustments thereafter on an annual basis,
in accordance with One-Year CMT (see "-- The Indices" below), and all of such
loans have original terms to maturity of 30 years. Approximately 60.75% of the
Pool 2 Mortgage Loans provide for payment of interest at the related Mortgage
Rate, but no payment of principal, for a period of five years, in each case
following the origination of the related Mortgage Loan. Following such five-year
interest-only period, the Scheduled Payment with respect to each such Pool 2
Mortgage Loan will be adjusted annually to an amount sufficient to amortize the
principal balance of such Mortgage Loan over its remaining term and to pay
interest at the related Mortgage Rate.

      As of the Cut-off Date, with respect to the Pool 2 Mortgage Loans, the
weighted average Mortgage Rate is approximately 4.351% per annum, the weighted
average Servicing Fee Rate is approximately 0.250% per annum, the weighted
average margin is approximately 2.750% per annum, the weighted average remaining
term to maturity is approximately 339 months, and the weighted average interest
only remaining term is approximately 40 months.

      The initial Periodic Cap for the Pool 2 Mortgage Loans is generally 5.000%
for the first adjustment date and the subsequent Periodic Cap for the Pool 2
Mortgage Loans is 2.000% thereafter. Generally, the Maximum Mortgage Rate for
each Pool 2 Mortgage Loan will equal the Mortgage Rate at origination of such
Mortgage Loan plus 5.000%.

      The Pool 2 Mortgage Loans were originated from June 2003 through February
2005. No more than approximately 2.79% of the Pool 2 Mortgage Loans are secured
by Mortgaged Properties located in any one zip code area. The latest stated
maturity date of any Pool 2 Mortgage Loan is March 2035.

      All of the Pool 2 Mortgage Loans were either originated or acquired by
Wells Fargo Bank, N.A., in the capacity of originator ("Wells Fargo"). Some of
the Pool 2 Mortgage Loans were made in connection with the relocation of
employees of various corporate employers. Some of these corporate employers
participate in Wells Fargo's relocation program.

      All of the Pool 2 Mortgage Loans are Relationship ARMs. A "Relationship
ARM" provides a reduced mortgage rate during the fixed-rate period described
above to a mortgagor who has established at the time of origination of the
Mortgage Loan certain banking relationships with Wells Fargo. The amount of the
reduction is based on the mortgagor maintaining certain accounts and balances.
In the event a mortgagor fails to maintain the required relationship, Wells
Fargo may, upon notice, increase the Mortgage Rate for the fixed-period by a
specified number of percentage points ranging from 0.125% to 0.500% (the amount
of any such increase when in effect, the "Incremental Rate" and the amount of
interest accrued at the Incremental

                                      S-25


Rate, the "Incremental Interest"). Any Incremental Interest will be treated as
additional servicing compensation and will not be available to make
distributions to Certificateholders.

      Certain general information with respect to the Mortgage Loans is set
forth below. Prior to the Closing Date, Mortgage Loans may be removed from the
Trust Fund and other mortgage loans may be substituted therefor. The Depositor
believes that the information set forth herein with respect to the Mortgage
Loans as presently constituted is representative of the characteristics of the
Mortgage Loans as they will be constituted at the Closing Date, although the
numerical data and certain other characteristics of the Mortgage Loans described
herein may vary within a range of plus or minus 5%.

      None of the Mortgage Loans will be guaranteed by any governmental agency.
All of the Mortgage Loans will have been assigned to the Trust Fund by the
Depositor, which, in turn, will have acquired them from the Seller pursuant to
an agreement (the "Mortgage Loan Purchase Agreement") between the Depositor and
the Seller. The Mortgage Loans have been acquired by the Seller, directly or
indirectly, from the Originators in the ordinary course of its business. All of
the Mortgage Loans were underwritten by the Originators substantially in
accordance with the underwriting criteria specified herein. See "--
Underwriting Standards" below. The Servicers will service the Mortgage Loans
pursuant to existing Servicing Agreements with the Seller, which agreements have
been assigned to the Trust Fund.

      The Mortgage Loans generally provide for payments due on the first day of
each month (the "Due Date"). Due to the provisions for monthly advances by the
applicable Servicer, scheduled payments made by the borrowers either earlier or
later than the scheduled Due Dates thereof will not affect the amortization
schedule or the relative application of such payments to principal and interest.

      As of the Cut-off Date, none of the Mortgage Loans was more than 29 days
delinquent.

      No Mortgage Loan had a Loan-to-Value Ratio at origination of more than
100.00%. Approximately 1.44% of the Pool 1 mortgage loans had an Effective
Loan-to-Value Ratio at origination of greater than 80%. Approximately 0.26% of
the Pool 2 mortgage loans had a Loan-to-Value Ratio at origination of greater
than 80%. Substantially all of the Mortgage Loans with an Effective
Loan-to-Value Ratio or Loan-to-Value Ratio (as applicable) at origination of
greater than 80% are covered by a primary mortgage insurance policy. All of the
Mortgage Loans originated by MSCC with Loan-to-Value Ratios greater than 80% at
origination were originated under MSCC's FlexSource(TM) Loans program, and all
of the Mortgage Loans originated by Merrill Lynch Credit Corporation ("MLCC")
with Loan-to-Value Ratios greater than 80% at origination were originated by
MLCC under its Mortgage 100(SM) or Parent Power(R) programs. In each case, in
addition to being secured by real property, such Mortgage Loans may be secured
by a security interest in a limited amount of additional collateral owned by the
borrower or are supported by a third-party guarantee as described at "-- The
Additional Collateral Loans" below.

      The "Loan-to-Value Ratio" of a Mortgage Loan at any given time is a
fraction, expressed as a percentage, the numerator of which is the principal
balance of the related Mortgage Loan at the date of determination and the
denominator of which is (a) in the case of a purchase, the lesser of the selling
price of the Mortgaged Property and its appraised value determined in an
appraisal obtained by the originator at origination of such Mortgage Loan, or
(b) in the case of a refinance,

                                      S-26


the appraised value of the Mortgaged Property at the time of such refinance. No
assurance can be given that the value of any Mortgaged Property has remained or
will remain at the level that existed on the appraisal or sales date. If
residential real estate values generally or in a particular geographic area
decline, the Loan-to-Value Ratios might not be a reliable indicator of the rates
of delinquencies, foreclosures and losses that could occur with respect to such
Mortgage Loans. The "Effective Loan-to-Value Ratio" means a fraction, expressed
as a percentage, the numerator of which is the original Stated Principal Balance
of the related Mortgage Loan, less the amount secured by the related Additional
Collateral required at the time of origination, if any, and the denominator of
which is the appraised value of the related Mortgaged Property at such time, or
in the case of a Mortgage Loan financing the acquisition of the Mortgaged
Property, the sales price of the Mortgaged Property if such sales price is less
than such appraised value.

      As set forth in the "Credit Scores" table below, credit scores have been
supplied with respect to the mortgagors. Credit scores are obtained by many
mortgage lenders in connection with mortgage loan applications to help assess a
borrower's credit-worthiness. Credit scores are generated by models developed by
a third party which analyzed data on consumers in order to establish patterns
which are believed to be indicative of the borrower's probability of default.
The credit score is based on a borrower's historical credit data, including,
among other things, payment history, delinquencies on accounts, levels of
outstanding indebtedness, length of credit history, types of credit, and
bankruptcy experience. Credit scores range from approximately 250 to
approximately 900, with higher scores indicating an individual with a more
favorable credit history compared to an individual with a lower score. However,
a credit score purports only to be a measurement of the relative degree of risk
a borrower represents to a lender, i.e., that a borrower with a higher score is
statistically expected to be less likely to default in payment than a borrower
with a lower score. In addition, it should be noted that credit scores were
developed to indicate a level of default probability over a two-year period
which does not correspond to the life of a mortgage loan. Furthermore, credit
scores were not developed specifically for use in connection with mortgage
loans, but for consumer loans in general. Therefore, a credit score does not
take into consideration the effect of mortgage loan characteristics (which may
differ from consumer loan characteristics) on the probability of repayment by
the borrower. There can be no assurance that a credit score will be an accurate
predictor of the likely risk or quality of the related mortgage loan.

THE ADDITIONAL COLLATERAL LOANS

      Approximately 11.28% of the Pool 1 Mortgage Loans are "Additional
Collateral Loans" as described below. Those Mortgage Loans with Loan-to-Value
Ratios at origination in excess of 80% originated under the MSCC FlexSource(TM)
Loans program or under MLCC's Mortgage 100(SM) or Parent Power(R) programs are,
in general, in addition to being secured by real property, also either (i)
secured by a security interest in additional collateral (generally securities)
owned by the borrower (referred to as Mortgage 100(SM) Loans in the MLCC
program) or (ii) supported by a third party guarantee (usually a parent of the
borrower), which in turn was secured by a security interest in collateral
(normally securities) or by a lien on residential real estate of the guarantor
(and/or supported by the right to draw on a home equity line of credit extended
by MLCC to the guarantor), such loans in clause (ii) being referred to as
"Parent Power(R) Loans" in the case of the MLCC program and such loans in
clauses (i) and (ii) being referred to as "FlexSource(TM) Loans" in the case of
the MSCC program. Such Mortgage Loans secured by collateral described in clauses
(i) and (ii) are also collectively referred to as "Additional

                                      S-27


Collateral Loans" and the collateral referred to in clauses (i) and (ii) is
referred to herein as "Additional Collateral." The amount of Additional
Collateral generally does not exceed 30% of the loan amount, although the amount
of Additional Collateral may exceed 30% of the loan amount if the original
principal amount of the loan exceeds $1,000,000. In limited cases, either MSCC
or MLCC may require Additional Collateral in excess of 30% of the loan amount as
part of the underwriting decision. The requirement to maintain Additional
Collateral generally terminates when the principal balance of an Additional
Collateral Loan is reduced to a predetermined amount set forth in the related
pledge agreement or guaranty agreement, as applicable, or when the Loan-to-Value
Ratio is reduced to the originator's applicable Loan-to-Value Ratio limit for
that loan by virtue of an increase in the appraised value of the related
Mortgaged Property as determined by the applicable originator. The pledge
agreement and the guaranty agreement, as applicable, and the security interest
in the Additional Collateral, if any, provided in the case of an Additional
Collateral Loan will be assigned to the Trustee as part of the Trust Fund. To
the extent Mortgage Loans include any Additional Collateral Loans that are
supported by a guarantee that is secured by a lien on residential real estate,
the lien will not be transferred to the Depositor or the Trustee; however, MSCC
or MLCC, as applicable, will be obligated to make all reasonable efforts to
realize on any such lien if the related Mortgage Loan defaults and is
accelerated or is liquidated upon default as permitted by the related pledge
agreement and applicable state law.

      On or prior to the Closing Date, the Depositor will have assigned to the
Trust Fund its rights under limited purpose surety bonds issued to MLCC and
MSCC, respectively, by AMBAC Assurance Corporation (the "Limited Purpose Surety
Bonds"), each of which is intended to guarantee the receipt by the Trust Fund of
certain shortfalls in the net proceeds realized from the liquidation of any
required Additional Collateral (such amount not to exceed 30% of the original
principal amount of the related Additional Collateral Loan) to the extent that
any such shortfall results in a loss of principal as an Additional Collateral
Loan that becomes a Liquidated Mortgage Loan, as more particularly described in,
and as limited by, the terms and provisions of the applicable Limited Purpose
Surety Bond. The Limited Purpose Surety Bonds will not cover any payments on the
Certificates that are recoverable or sought to be recovered as a voidable
preference under applicable law.

      No assurance can be given as to the amount of proceeds, if any, that might
be realized from Additional Collateral. Proceeds from the liquidation of any
Additional Collateral will be included in net proceeds only when permitted by
applicable state law and by the terms of the related pledge or guaranty
agreement, as applicable.

THE INDICES

      The Mortgage Rate for all of the Mortgage Loans will be adjusted monthly,
semi-annually or annually on the related adjustment date. The index for the
Mortgage Rate borne by all of the Mortgage Loans may be calculated as follows
(in each case, rounded to the nearest one-eighth of one percent):

            ONE-MONTH LIBOR. The Mortgage Rate borne by approximately 59.54% of
      the Pool 1 Mortgage Loans (by Aggregate Cut-off Date Balance) is adjusted
      every month to equal the London interbank offered rate for one-month U.S.
      dollar deposits as listed under "Money Rates" in The Wall Street Journal
      most recently available as of 15, 30, 32 or 45 days, as applicable, prior
      to the related adjustment date ("One-Month LIBOR") plus a margin ranging
      from 1.250% to 2.250%.

            SIX-MONTH LIBOR. The Mortgage Rate borne by approximately 39.30% of
      the Pool 1 Mortgage Loans (by Aggregate Cut-off Date Balance) is adjusted
      every six months to equal the London interbank offered rate for six-month
      U.S. dollar deposits as listed under "Money Rates" in The Wall Street
      Journal most recently available as of 15, 30 or 45 days, as applicable,
      prior to the related adjustment date ("Six-Month LIBOR") plus a margin
      ranging from 0.000% to 2.625%.

            PRIME RATE. The Mortgage Rate borne by approximately 1.16% of the
      Pool 1 Mortgage Loans (by Aggregate Cut-off Date Balance) is adjusted
      every six months to equal the bank prime rate as listed in The Wall Street
      Journal most recently available as of 45 days prior to the related
      adjustment date ("Prime Rate") plus a margin ranging from 0.000% to
      0.500%.

            ONE-YEAR CMT. The Mortgage Rate borne by all of the Pool 2 Mortgage
      Loans is adjusted annually to equal the weekly average yield on United
      States Treasury Securities adjusted to a constant maturity of one year, as
      made available by the Federal Reserve Board, published in Federal Reserve
      Statistical Release H.15 (519) ("One-Year CMT") and most recently
      available as of the date 45 days before the applicable adjustment date,
      plus a margin of 2.750%.

ASSIGNMENT OF THE MORTGAGE LOANS

      Under the Mortgage Loan Purchase Agreement, RWT Holdings, Inc. (the
"Seller") will sell the Mortgage Loans to the Depositor. The Seller will make
certain representations, warranties and covenants relating to, among other
things, certain characteristics of the Mortgage Loans. Subject to the
limitations described below, the Seller will be obligated as described herein to
purchase or substitute a similar mortgage loan for any Mortgage Loan as to which
there exists deficient documentation or as to which there has been an uncured
breach of any such representation or warranty relating to the characteristics of
the Mortgage Loan that materially and adversely affects the value of such
Mortgage Loan or the interests of the Certificateholders in such Mortgage Loan
(a "Defective Mortgage Loan"). See "Loan Program -- Representations by Sellers;
Repurchases" in the accompanying prospectus.

      Pursuant to a pooling and servicing agreement (the "Pooling and Servicing
Agreement"), dated as of September 1, 2005, among Sequoia Residential Funding,
Inc., as depositor (the

                                      S-43


"Depositor"), Wells Fargo Bank, N.A., in the capacities of master servicer (the
"Master Servicer") and securities administrator (the "Securities Administrator")
and HSBC Bank USA, National Association, as trustee (the "Trustee"), on the
Closing Date the Depositor will sell, transfer, assign, set over and otherwise
convey without recourse to the Trust Fund all of its rights to the Mortgage
Loans and its rights under the Mortgage Loan Purchase Agreement (including the
right to enforce the Seller's purchase obligation). The obligations of the
Seller with respect to the Certificates are limited to the Seller's obligation
to purchase or substitute for Defective Mortgage Loans.

      In connection with such transfer and assignment of the Mortgage Loans, the
Depositor will deliver or cause to be delivered to the Trustee or its custodian,
among other things, the original promissory note (the "Mortgage Note") (and any
modification or amendment thereto) endorsed in blank without recourse, the
original instrument creating a first lien on the related Mortgaged Property (the
"Mortgage") with evidence of recording indicated thereon, an assignment in
recordable form of the Mortgage, the title policy with respect to the related
Mortgaged Property and, if applicable, all recorded intervening assignments of
the Mortgage and any riders or modifications to such Mortgage Note and Mortgage
(except for any such document other than Mortgage Notes not available on the
Closing Date, which will be delivered to the Trustee as soon as the same is
available to the Depositor) (collectively, the "Mortgage File"). Assignments of
the Mortgage Loans to the Trustee (or its nominee) will be recorded in the
appropriate public office for real property records, except in states where, in
the opinion of counsel, such recording is not required to protect the Trustee's
interest in the Mortgage Loans against the claim of any subsequent transferee or
any successor to or creditor of the Depositor.

      The custodian, on behalf of the Trustee, will review each Mortgage File
within 270 days of the Closing Date (or promptly after the custodian's receipt
of any document permitted to be delivered after the Closing Date) and will hold
such Mortgage Files in trust for the benefit of the Certificateholders. If at
the end of such 270-day period, any document in a Mortgage File is found to be
missing or defective in a material respect and the Seller does not cure such
omission or defect within 180 days after its receipt of notice from the
custodian, then the Seller is obligated to purchase the related Defective
Mortgage Loan from the Trust Fund at a price equal to the sum of (a) 100% of the
Stated Principal Balance thereof, (b) unpaid accrued interest thereon from the
Due Date to which interest was last paid by the mortgagor to the Due Date
immediately preceding the repurchase and (c) any unreimbursed Monthly Advances
and servicing advances not included in clauses (a) and (b) above. Rather than
purchase the Defective Mortgage Loan as provided above, the Seller may remove
such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and
substitute in its place one or more mortgage loans of like kind (such loan a
"Replacement Mortgage Loan"); provided, however, that such substitution is
permitted only within two years after the Closing Date and may not be made
unless an opinion of counsel is provided to the effect that such substitution
would not disqualify the REMIC elections or result in the imposition of a
REMIC-related prohibited transaction tax under the Code.

      Any Replacement Mortgage Loan generally will, on the date of substitution,
among other characteristics set forth in the Mortgage Loan Purchase Agreement,
(i) have an outstanding principal balance, after deduction of all Scheduled
Payments due in the month of substitution, not in excess (and not less than 90%)
of the Stated Principal Balance of the Deleted Mortgage Loan (the amount of any
shortfall to be deposited in the Distribution Account by the Seller not

                                      S-44


later than the succeeding Determination Date and held for distribution to the
Certificateholders on the related Distribution Date), (ii) have a maximum
Mortgage Rate not less than (and not more than two percentage points greater
than) the maximum mortgage rate of the Deleted Mortgage Loan, (iii) have a gross
margin not less than that of the Deleted Mortgage Loan and, if Mortgage Loans of
a Mortgage Pool equal to 1% or more of the Cut-off Date balance of such Mortgage
Pool have become Deleted Mortgage Loans, not more than two percentage points
more than that of the Deleted Mortgage Loan, (iv) have an Effective
Loan-to-Value Ratio or Loan-to-Value Ratio (as applicable) not higher than that
of the Deleted Mortgage Loan, (v) have a remaining term to maturity not greater
than (and not more than one year less than) that of the Deleted Mortgage Loan,
(vi) not permit conversion of the related Mortgage Rate to a permanent fixed
Mortgage Rate, (vii) have the same or higher credit score, (viii) have an
initial interest adjustment date no earlier than five months before (and no
later than five months after) the initial interest adjustment date of the
Deleted Mortgage Loan, (ix) be a "qualified replacement mortgage" within the
meaning of Section 860G(a)(4) of the Code and (x) comply with all of the
representations and warranties set forth in the Mortgage Loan Purchase
Agreement. This cure, repurchase or substitution obligation constitutes the sole
remedy available to the Certificateholders or the Trustee for omission of, or a
material defect in, a Mortgage File.

UNDERWRITING STANDARDS

      MSCC, MLCC and Countrywide originated approximately 62.38%, 15.57% and
13.65% of the Pool 1 Mortgage Loans, respectively; Wells Fargo originated or
acquired all of the Pool 2 Mortgage Loans; and the remaining Mortgage Loans were
originated by various mortgage lending institutions (collectively with MSCC,
MLCC, Countrywide and Wells Fargo, the "Originators"). Each Originator will
represent and warrant that each of the Mortgage Loans originated and/or sold by
it was underwritten in accordance with standards consistent with those utilized
by mortgage lenders generally during the period of origination.

      When originating or acquiring mortgage loans, the Originators generally do
so in accordance with underwriting guidelines established by each of them, and
such guidelines differ among the applicable Originators in various respects.
From time to time, exceptions to an Originator's underwriting policies may be
made. Such exceptions may be made on a loan-by-loan basis at the discretion of
the Originator's underwriter. The following is a general summary of underwriting
guidelines provided to the Depositor by certain Originators. The following does
not purport to be a complete or precise description of the underwriting
standards of any of the Originators.

      Underwriting standards are applied by or on behalf of a lender to evaluate
a borrower's credit standing and repayment ability, and the value and adequacy
of the related Mortgaged Property as collateral. In general, a prospective
borrower applying for a loan is required to fill out a detailed application
designed to provide to the underwriting officer pertinent credit information. As
part of the description of the borrower's financial condition, the borrower
generally is required to provide a current list of assets and liabilities and a
statement of income and expenses, as well as an authorization to apply for a
credit report which summarizes the borrower's credit history with local
merchants and lenders and any record of bankruptcy. In most cases, an employment
verification is obtained from an independent source (typically the borrower's
employer), which verification reports, among other things, the length of
employment with that organization, the current salary, and whether it is
expected that the borrower will

                                      S-45


continue such employment in the future. If a prospective borrower is
self-employed, the borrower may be required to submit copies of signed tax
returns. The borrower may also be required to authorize verification of deposits
at financial institutions where the borrower has demand or savings accounts. See
"Loan Program -- Underwriting Standards" in the prospectus.

      A lender may also originate mortgage loans pursuant to alternative sets of
underwriting criteria under reduced or limited documentation programs. These
programs are designed to facilitate the loan approval process. Under these
programs, certain documentation concerning income/employment and asset
verification is reduced or excluded. Loans underwritten under these programs are
generally limited to borrowers who have demonstrated an established ability and
willingness to repay the mortgage loans in a timely fashion. Permitted maximum
loan-to-value ratios under these programs are generally more restrictive than
those under the lender's standard underwriting criteria.

      From time to time, exceptions to a lender's underwriting policies may be
made. Such exceptions may be made on a loan-by-loan basis at the discretion of
the lender's underwriter. Exceptions may be made after careful consideration of
certain mitigating factors such as borrower liquidity, employment and
residential stability and local economic conditions.

      MSCC. MSCC is an indirect wholly-owned subsidiary of Morgan Stanley. MSCC
is a retail residential mortgage lender that originates and services loans for
borrowers who are clients of Morgan Stanley. Clients are introduced to MSCC
typically through Morgan Stanley brokerage account relationships, and through
Discover Card cardmember relationships. MSCC utilizes each of these companies'
sales forces to reinforce brand identity and customer relationships, in addition
to marketing to these consumers directly through the mail or via inserts in
existing account statements. MSCC is structured to operate nationally on a
remote basis. Clients are provided toll-free telephone number access to loan
officers who will discuss alternative products to meet specific needs. Loan
officers take mortgage loan applications, and lead customers through the entire
mortgage loan origination process. MSCC's loan origination, servicing, and
collection systems are fully integrated and provide a more flexible,
user-friendly technology foundation and enhanced customer service.

      In order to provide convenient customer service for all U.S. properties,
MSCC maintains corporate licensing/authorization to conduct business in all 50
states. MSCC's loans are serviced and supported by seller's servicing center
located in Sioux Falls, South Dakota.

      Generally, a potential borrower may submit a written or telephone
application which provides pertinent information about the applicant's ability
to repay the proposed loan. Information supporting the potential borrower's
assets, liabilities, income and expenses is required. Such information typically
includes verification of income, deposits and mortgage payment history.
Additionally, MSCC obtains and reviews a property appraisal, title policy, a
credit bureau report of the applicant's credit history, analysis of income
supporting repayment ability and proof of insurance coverage.

      A potential borrower's ability to make the proposed loan payments is
measured by the applicant's income, credit, residence stability and assets. One
test to determine this ability is the debt-to-income ratio, which is the
borrower's total monthly debt service divided by total monthly gross income.
MSCC typically allows for a debt-to-income ratio of 45%. Debt-to-income

                                      S-46


exceptions must be approved by the appropriate level underwriter, and supported
by compensating factors.

      The adequacy of the mortgaged property as security for the proposed
mortgage loan will generally be determined by an appraisal acceptable to MSCC.
Appraisals are conducted by independent appraisers acceptable to MSCC. If the
proposed loan amount exceeds $1,000,000, a second appraisal will be required.

      Loans that have a loan-to-value ratio in excess of 80% are, in general,
also either (i) secured by a security interest in additional collateral
(generally securities) owned by the borrower or (ii) supported by a third party
guarantee (generally a parent of the borrower), which in turn is secured by a
security interest in collateral (generally securities). Such loans are also
referred to herein as "FlexSource(TM) Loans", and the collateral referred to in
clauses (i) and (ii) is herein referred to as "Additional Collateral". The
amount of such Additional Collateral generally does not exceed 30% of the loan
amount, although the amount of the Additional Collateral may exceed 30% of the
loan amount in some cases. In limited cases, MSCC may require Additional
Collateral in excess of 30% of the loan amount as part of the underwriting
decision. The requirement to maintain Additional Collateral generally terminates
when the principal balance of such FlexSource(TM) Loan is reduced to a
predetermined amount set forth in the related pledge agreement or guaranty
agreement, as applicable, or when the loan-to-value ratio for such
FlexSource(TM) Loan is reduced to MSCC's applicable loan-to-value ratio limit
for such loan by virtue of an increase in the appraised value of the mortgaged
property securing such loan as determined by MSCC. The pledge agreement and the
guaranty agreement, as applicable, and the security interest in such Additional
Collateral, if any, provided in the case of a FlexSource(TM) Loan will be
assigned to the Trustee and part of the Trust Fund.

      No assurance can be given as to the amount of proceeds, if any, that might
be realized from such Additional Collateral. Proceeds from the liquidation of
any such Additional Collateral will be included in net proceeds only when
permitted by applicable state law and by the terms of the related pledge
agreement or guaranty agreement, as applicable.

      Wells Fargo. The following is a summary of Wells Fargo's "general"
underwriting standards and the substantially less restrictive underwriting
criteria applicable to the Originator's "retention program."

      The Wells Fargo Underwriting Guidelines evaluate the applicant's credit
standing and ability to repay the loan, as well as the value and adequacy of the
mortgaged property as collateral. The Wells Fargo Underwriting Guidelines
represent a balancing of several factors that may affect the ultimate recovery
of the loan amount, including, among others, the amount of the loan, the ratio
of the loan amount to the property value (i.e., generally the lower of the
appraised value of the mortgaged property and the purchase price), the
borrower's means of support and the borrower's credit history. The Wells Fargo
Underwriting Guidelines may vary according to the nature of the borrower or the
type of loan, since differing characteristics may be perceived as presenting
different levels of risk.

      All of the Mortgage Loans provide for a reduced mortgage rate during the
fixed-rate period to a mortgagor who at the time of origination of the Mortgage
Loan has or promises to establish certain banking relationships with Wells
Fargo. The amount of the reduction is based

                                      S-47


on the mortgagor maintaining certain accounts and balances. In the event a
mortgagor fails to maintain the required relationship, Wells Fargo may, at its
sole discretion and upon notice, increase the mortgage rate for the fixed-rate
period by a specified number of percentage points ranging from 0.125% to 0.500%.

      Wells Fargo supplements the mortgage loan underwriting process with either
its own proprietary scoring system or scoring systems developed by third parties
such as Freddie Mac's Loan Prospector, Fannie Mae's Desktop Underwriter or
scoring systems developed by private mortgage insurance companies. These scoring
systems assist Wells Fargo in the mortgage loan approval process by providing
consistent, objective measures of borrower credit and certain loan attributes.
Such objective measures are then used to evaluate loan applications and assign
each application a "mortgage score".

      The portion of the mortgage score related to borrower credit history is
generally based on computer models developed by a third party. These models
evaluate information available from three major credit reporting bureaus
regarding historical patterns of consumer credit behavior in relation to default
experience for similar types of borrower profiles. A particular borrower's
credit patterns are then considered in order to derive a "FICO score" which
indicates a level of default probability over a two-year period.

      The mortgage score is used to determine the type of underwriting process
and which level of underwriter will review the loan file. For transactions that
are determined to be low-risk transactions, based upon the mortgage score and
other parameters (including the mortgage loan production source), the lowest
underwriting authority is generally required. For moderate and higher risk
transactions, higher level underwriters and a full review of the mortgage file
are generally required. Borrowers who have a satisfactory mortgage score (based
upon the mortgage loan production source) are generally subject to streamlined
credit review (which relies on the scoring process for various elements of the
underwriting assessments). Such borrowers may also be eligible for a reduced
documentation program and are generally permitted greater latitude in the
application of borrower total debt-to-income ratio.

      A prospective borrower applying for a mortgage loan is required to
complete a detailed application. The loan application elicits pertinent
information about the applicant, with particular emphasis on the applicant's
financial health (assets, liabilities, income and expenses), the property being
financed and the type of loan desired. A self-employed applicant may be required
to submit his or her most recent signed federal income tax returns. With respect
to every applicant, credit reports are obtained from commercial reporting
services, summarizing the applicant's credit history with merchants and lenders.
Generally, significant unfavorable credit information reported by the applicant
or a credit reporting agency must be explained by the applicant. The credit
review process generally is streamlined for borrowers with a qualifying credit
score.

      Verifications of employment, income, assets or mortgages may be used to
supplement the loan application and the credit report in reaching a
determination as to the applicant's ability to meet his or her monthly
obligations on the proposed mortgage loan, as well as his or her other mortgage
payments (if any), living expenses and financial obligations. Mortgage
verification involves obtaining information regarding the borrower's payment
history with respect to any existing mortgage the applicant may have.
Verifications of income, assets or mortgages may be

                                      S-48


waived under certain programs offered by Wells Fargo, but the Wells Fargo
Underwriting Guidelines require, in most instances, a verbal or written
verification of employment to be obtained. In addition, the loan applicant may
be eligible for a loan approval process permitting reduced documentation. The
above referenced reduced documentation options and waivers limit the amount of
documentation required for an underwriting decision and have the effect of
increasing the relative importance of the credit report and the appraisal.

      Documentation requirements vary based upon a number of factors, including
the purpose of the loan, the amount of the loan, the ratio of the loan amount to
the property value and the mortgage loan production source. Wells Fargo accepts
alternative methods of verification in those instances when verifications are
part of the underwriting decision; for example, salaried income may be
substantiated either by means of a form independently prepared and signed by the
applicant's employer or by means of the applicant's most recent paystub and/or
W-2. Loans underwritten using alternative verification methods are considered by
Wells Fargo to have been underwritten with "full documentation".

      In general, borrowers applying for loans must demonstrate that the ratio
of their total monthly debt to their monthly gross income does not exceed
certain maximum levels. In the case of adjustable-rate mortgage loans, the
interest rate used to determine a mortgagor's monthly payment for purposes of
such ratios may, in certain cases, be the initial mortgage interest rate or
another interest rate, which, in either case, is lower than the sum of the index
rate that would have been applicable at origination plus the applicable margin.
In the case of a mortgage loan referred by Wells Fargo's private mortgage
banking division, for certain applicants referred by this division, qualifying
income may be based on an "asset dissipation" approach under which future income
is projected from the assumed liquidation of a portion of the applicant's
specified assets. Secondary financing is permitted on mortgage loans under
certain circumstances. In those cases, the payment obligations under both
primary and secondary financing are included in the computation of the total
debt to income ratio, and the combined amount of primary and secondary loans
will be used to calculate the combined loan-to-value ratio. In evaluating an
application with respect to a "non-owner-occupied" property, which Wells Fargo
defines as a property leased to a third party by its owner (as distinct from a
"second home," which Wells Fargo defines as an owner-occupied, non-rental
property that is not the owner's principal residence), Wells Fargo will include
projected rental income net of certain mortgagor obligations and other assumed
expenses or loss from such property to be included in the applicant's monthly
gross income or total monthly debt in calculating the foregoing ratios. A
mortgage loan secured by a two- to four-family mortgaged property is considered
to be an owner-occupied property if the borrower occupies one of the units;
rental income on the other units is generally taken into account in evaluating
the borrower's ability to repay the mortgage loan.

      Mortgage loans will not generally have had at origination a loan-to-value
ratio in excess of 95%. The "loan-to-value ratio" is the ratio, generally
expressed as a percentage, of the principal amount of the mortgage loan at
origination to the lesser of (i) the appraised value of the related mortgaged
property, as established by an appraisal obtained by the originator generally no
more than four months prior to origination (or, with respect to
newly-constructed properties, no more than twelve months prior to origination),
or (ii) the sale price for such property. In some instances, the loan-to-value
ratio is based on an appraisal that was obtained by the originator more than
four months prior to origination, provided that (i) a recertification of the
original appraisal is obtained and (ii) the original appraisal was obtained no
more than twelve months

                                      S-49


prior to origination. For the purpose of calculating the loan-to-value ratio of
any mortgage loan that is the result of the refinancing of an existing mortgage
loan, the appraised value of the related mortgaged property is generally
determined by reference to an appraisal obtained in connection with the
origination of the replacement loan. In connection with certain of its
originations, Wells Fargo currently obtains appraisals through Value Information
Technology, Inc., an entity jointly owned by Wells Fargo and an unaffiliated
third party.

      Wells Fargo originates mortgage loans with loan-to-value ratios in excess
of 80% either with or without the requirement to obtain primary mortgage
insurance. In some cases for which such primary mortgage insurance is obtained,
the excess over 75% (or such lower percentage as Wells Fargo may require at
origination) will be covered by primary mortgage insurance (subject to certain
standard policy exclusions for default arising from, among other things, fraud
or negligence in the origination or servicing of a mortgage loan, including
misrepresentation by the mortgagor or other persons involved in the origination
thereof) from an approved primary mortgage insurance company until the unpaid
principal balance of the mortgage loan is reduced to an amount that will result
in a loan-to-value ratio less than or equal to 80%. In cases for which such
primary mortgage insurance is not obtained, loans having loan-to-value ratios
exceeding 80% are required to be secured by primary residences or second homes
(excluding cooperatives). Generally, each loan originated without primary
mortgage insurance will have been made at an interest rate that was higher than
the rate would have been had the loan-to-value ratios been 80% or less or had
primary mortgage insurance been obtained.

      A borrower whose mortgage loan is serviced by Wells Fargo may be eligible
for Wells Fargo's retention program. Provided such a borrower is current in his
or her mortgage payment obligations, Wells Fargo may permit a refinancing of the
mortgage loan to a current market interest rate without applying any significant
borrower credit or property underwriting standards. As a result, borrowers who
qualify under the retention program may not need to demonstrate that their total
monthly debt obligations in relation to their monthly income level does not
exceed a certain ratio; Wells Fargo may not obtain a current credit report for
the borrower or apply a new credit score to the refinanced loan; and the
borrower may not be required to provide any verifications of current employment,
income level or extent of assets. In addition, no current appraisal or
indication of market value may be required with respect to the properties
securing mortgage loans that are refinanced under the retention program.

      Wells Fargo may also apply the retention program to its existing borrowers
who obtain new purchase money mortgage loans secured by primary residences when
the initial principal balance of the new loan would not exceed 200% of the
original principal balance of the previous loan. Borrowers may be pre-approved
under this program if they have a satisfactory payment history with Wells Fargo,
as well as a satisfactory FICO score. Wells Fargo may waive verifications of
borrower income and assets under this program and may not impose any limitation
on a borrower's total debt ratio. A new appraisal will be obtained with respect
to the residence securing the new purchase money mortgage loan.

                         DESCRIPTION OF THE CERTIFICATES

GENERAL

      On or about September 29, 2005 (the "Closing Date"), the Certificates will

Agreement. The following summaries are subject to, and are qualified in their
entirety by reference to, the provisions of the Pooling and Servicing Agreement.
When particular provisions or terms used in the Pooling and Servicing Agreement
are referred to, the actual provisions (including definitions of terms) are

            Class 1-B6 Certificates (the "Group 1 Subordinate Certificates");

      -     the Class 2-A1, Class 2-A2 and Class 2-AR Certificates (the "Group 2
            Senior Certificates," and together with the Group 1 Senior
            Certificates, the "Senior Certificates); and

      -     the Class 2-B1, Class 2-B2, Class 2-B3, Class 2-B4, Class 2-B5 and
            Class 2-B6 Certificates (the "Group 2 Subordinate Certificates", and
            together with the Group 1 Subordinate Certificates, the "Subordinate
            Certificates").

      The Group 1 Senior Certificates and the Group 1 Subordinate Certificates
are referred to herein as the "Group 1 Certificates." Distributions of interest
and principal on the Group 1 Certificates will be based solely on interest and
principal received on, or advanced with respect to, the Pool 1 Mortgage Loans.
The Group 2 Senior Certificates and the Group 2 Subordinate Certificates are
referred to herein as the "Group 2 Certificates." Distributions of interest and
principal on the Group 2 Certificates will be based solely on interest and
principal received on, or advanced with respect to, the Pool 2 Mortgage Loans.

      Each group of the Group 1 Certificates and the Group 2 Certificates is
referred to herein as a "Certificate Group".

      The Senior Certificates (other than the Class 1-LTR Certificates) and the
Class 1-B1, Class 1-B2, Class 1-B3, Class 2-B1, Class 2-B2 and Class 2-B3
Certificates are sometimes collectively referred to herein as the "Offered
Certificates." Only the Offered Certificates are offered under this prospectus
supplement. The Class 1-LTR, Class 1-B4, Class 1-B5, Class 1-B6, Class 2-B4,
Class 2-B5 and Class 2-B6 Certificates are collectively referred to as the
"Privately-Offered Certificates." The Class 1-XA and Class 1-XB Certificates are
collectively referred to as the "Class X Certificates." The Privately-Offered
Certificates are not offered under this prospectus supplement. Accordingly, the
description of the Privately-Offered Certificates provided in this prospectus
supplement is solely for informational purposes. The

                                      S-51


Class 1-A1, Class 1-A2, Class 1-B1 and Class 1-B2 Certificates are sometimes
collectively referred to herein as the "LIBOR Certificates" for the purposes of
describing interest payments with respect to such classes.

      The Offered Certificates will be issued in the initial Class Principal
Amounts set forth in the table under "Summary -- Offered Certificates." The
Class 1-B4, Class 1-B5, Class 1-B6, Class 2-B4, Class 2-B5 and Class 2-B6
Certificates will be issued in the approximate initial Class Principal Amounts
of $697,000, $543,000, $310,325, $348,000, $348,000 and $174,416, respectively.
The Class 1-LTR Certificate will not have a Class Principal Amount. The initial
Class Principal Amounts and Class Notional Amounts of each class may be
increased or decreased by up to 5% to the extent that the Stated Principal
Balance of the Mortgage Loans is increased or decreased as described at
"Description of the Mortgage Pools."

      The Offered Certificates (other than the Class 1-XA, Class 1-XB, Class
1-AR and Class 2-AR Certificates) will be issued in minimum denominations of
$100,000 initial principal amount each and integral multiples of $1 in excess
thereof. The Class 1-AR and Class 2-AR Certificates will be issued as a single
instrument in fully registered, definitive form, representing the entire
principal amount of such Certificate. Each of the Class 1-XA and Class 1-XB
Certificates will be issued as a single instrument evidencing a 100% percentage
interest in each such class.

      The Certificates represent beneficial ownership interests in a trust fund
(the "Trust Fund"), the assets of which on the Closing Date will consist
primarily of (1) the Pool 1 Mortgage Loans and the Pool 2 Mortgage Loans; (2)
such assets as from time to time are identified as deposited in respect of the
Mortgage Loans in the Custodial Accounts and the Distribution Account (see "--
Payments on Mortgage Loans; Accounts" below); (3) funds on deposit in the
Reserve Fund maintained for the benefit of the LIBOR Certificates; (4) the Trust
Fund's rights under various assignment, assumption and recognition agreements
pursuant to which the Seller and the Depositor assigned their respective
interests in the various underlying mortgage loan purchase agreements and
servicing agreements with respect to the Mortgage Loans originally entered into
between the Seller and the Originators; (5) the Trust Fund's rights under the
Mortgage Loan Purchase Agreement, as described above under "Description of the
Mortgage Pools -- Assignment of the Mortgage Loans," (6) property acquired by
foreclosure of the Mortgage Loans or deed in lieu of foreclosure; (7) any
applicable insurance policies; and (8) the proceeds of all of the foregoing. In
addition, the rights under certain pledged collateral accounts and the Limited
Purpose Surety Bonds with respect to the Additional Collateral Loans will be
assigned to the Trustee for the benefit of the Certificateholders. See
"Description of the Mortgage Pools -- The Additional Collateral Loans." Neither
the rights in the Additional Collateral nor the Reserve Fund will be part of any
REMIC.

      For purposes of allocating distributions of principal and interest to the
Offered Certificates, (1) the Group 1 Certificates will relate to, and solely
will be limited to collections from, the Pool 1 Mortgage Loans and (2) the Group
2 Certificates will relate to, and solely will be limited to collections from,
the Pool 2 Mortgage Loans. The rights of holders of Group 1 Subordinate
Certificates to receive distributions based upon principal and interest
collections from Pool 1 will be fully subordinated to the rights of the holders
of the Group 1 Senior Certificates (other than the Class X Certificates) and the
Class X Certificates (solely with respect to interest) to receive such
distributions, to the extent described herein. The rights of holders of

                                      S-52


Group 2 Subordinate Certificates to receive distributions based upon principal
and interest collections from Pool 2 will be fully subordinated to the rights of
the holders of the Group 2 Senior Certificates to receive such distributions, to
the extent described herein. In no event will the Group 1 Certificates have the
benefit of collections from Pool 2; and in no event will the Group 2
Certificates have the benefit of collections from Pool 1.

      Distributions on the Certificates will be made by the Securities
Administrator, on behalf of the Trustee, on the 20th day of each month, or if
such day is not a Business Day, on the first Business Day thereafter commencing
in October 2005 (each, a "Distribution Date"), to the persons in whose names
such Certificates are registered on the applicable Record Date. For this
purpose, a "Business Day" is any day other than (i) a Saturday or Sunday, or
(ii) a day on which banking institutions in the City of New York, New York, the
states of Maryland or Minnesota or the city in which the Corporate Trust Office
of the Trustee is located are authorized or obligated by law or Executive Order
to be closed. A "Record Date" with respect to the LIBOR Certificates and any
Distribution Date is the last Business Day preceding that Distribution Date (or
the Closing Date, in the case of the first Distribution Date) or, in the case of
all other Offered Certificates (including LIBOR Certificates that are
subsequently reissued as Definitive Certificates (as described below at "--
Book Entry Certificates")), the last Business Day of the month preceding the
month of that Distribution Date.

      Payments on each Distribution Date will be made by check mailed to the
address of the holder of the certificate (the "Certificateholder") entitled
thereto as it appears on the applicable certificate register or, in the case of
a Certificateholder who holds 100% of a notional class of Certificates or the
Class 1-AR or Class 2-AR Certificates or who holds Certificates with an
aggregate initial Class Principal Amount of $1,000,000 or more and who has so
notified the Securities Administrator in writing in accordance with the Pooling
and Servicing Agreement, by wire transfer in immediately available funds to the
account of such Certificateholder at a bank or other depository institution
having appropriate wire transfer facilities; provided, however, that the final
payment in retirement of the Certificates will be made only upon presentment and
surrender of such Certificates at the Corporate Trust Office of the Securities
Administrator. See " -- Book Entry Certificates" below for the method of payment
to Beneficial Owners of Book-Entry Certificates.

BOOK-ENTRY CERTIFICATES

      GENERAL. The Offered Certificates (other than the Class 1-AR and Class
2-AR Certificates) will be book-entry certificates (each, a class of "Book-Entry
Certificates") issued, maintained and transferred on the book-entry records of
The Depository Trust Company ("DTC") and its Participants.

      Each class of Book-Entry Certificates will be represented by one or more
global certificates which equal the initial principal balance of such class
registered in the name of the nominee of DTC. The Depositor has been informed by
DTC that DTC's nominee will be Cede & Co. No person acquiring an interest in a
Book-Entry Certificate (each, a "Beneficial Owner") will be entitled to receive
a physical certificate instrument evidencing such person's interest (a
"Definitive Certificates"), except as set forth in the prospectus under
"Description of the Securities -- Book-Entry Registration of Securities." Unless
and until Definitive Certificates are issued for the Book-Entry Certificates
under the limited circumstances described in the

                                      S-53


prospectus, all references to actions by Certificateholders with respect to the
Book-Entry Certificates will refer to actions taken by DTC upon instructions
from its Participants, and all references herein to distributions, notices,
reports and statements to Certificateholders with respect to the Book-Entry
Certificates will refer to distributions, notices, reports and statements to DTC
or Cede & Co., as the registered holder of the Book-Entry Certificates, for
distribution to Beneficial Owners by DTC in accordance with DTC procedures.
Beneficial Owners are only entitled to exercise their rights indirectly through
Participants in the DTC.

         REGISTRATION. Beneficial Owners will hold their interests in their
Offered Certificates through DTC in the United States, or, upon request, through
Clearstream Banking Luxembourg (hereafter, "Clearstream Luxembourg") or the
Euroclear System ("Euroclear") in Europe if they are participants of such
systems, or indirectly through organizations which are participants in such
systems. Clearstream Luxembourg and Euroclear will hold omnibus positions on
behalf of their participants through customers' securities accounts in
Clearstream Luxembourg's and Euroclear's names on the books of their respective
depositaries which in turn will hold such positions in customers' securities
accounts in the depositaries' names on the books of DTC. Citibank, N.A.
generally, but not exclusively, will act as depositary for Clearstream
Luxembourg and JPMorgan Chase Bank generally, but not exclusively, will act as
depositary for Euroclear (in such capacities, individually the "Relevant
Depositary" and collectively, the "European Depositaries").

         The Beneficial Owner's ownership interest in a Book-Entry Certificate
will be recorded on the records of the brokerage firm, bank, thrift institution
or other financial intermediary (each, a "Financial Intermediary") that
maintains the Beneficial Owner's account for such purpose. In turn, the
Financial Intermediary's ownership of such Book-Entry Certificate will be
recorded on the records of DTC (or of a participating firm (a "Participant")
that acts as agent for the Financial Intermediary, whose interest will in turn
be recorded on the records of DTC, if the Beneficial Owner's Financial
Intermediary is not a DTC participant and on the records of Clearstream
Luxembourg or Euroclear, as appropriate).

         Beneficial Owners will receive all payments of principal of, and
interest on, the Offered Certificates from the Securities Administrator, on
behalf of the Trustee through DTC and DTC participants. While the Book-Entry
Certificates are outstanding (except under the circumstances described below),
under the rules, regulations and procedures creating and affecting DTC and its
operations (the "Rules"), DTC is required to make book-entry transfers among
Participants on whose behalf it acts with respect to the Book-Entry Certificates
and is required to receive and transmit payments of principal of, and interest
on, the Book-Entry Certificates. Participants and indirect participants with
whom Beneficial Owners have accounts with respect to Book-Entry Certificates are
similarly required to make book-entry transfers and receive and transmit such
distributions on behalf of their respective Beneficial Owners. Accordingly,
although Beneficial Owners will not possess physical certificates, the Rules
provide a mechanism by which Beneficial Owners will receive payments and will be
able to transfer their interest.

         Beneficial Owners will not receive or be entitled to receive Definitive
Certificates representing their respective interests in the Book-Entry
Certificates, except under the limited circumstances described below. Unless and
until Definitive Certificates are issued, Beneficial Owners who are not
Participants may transfer ownership of Book-Entry Certificates only through
Participants and indirect participants by instructing such Participants and
indirect

                                      S-54


participants to transfer their interest by book-entry transfer, through DTC for
the account of the purchasers of such Certificates, which account is maintained
with their respective Participants. Under the Rules and in accordance with DTC's
normal procedures, transfer of ownership of Book-Entry Certificates will be
executed through DTC and the accounts of the respective Participants at DTC will
be debited and credited. Similarly, the Participants and indirect participants
will make debits or credits, as the case may be, on their records on behalf of
the selling and purchasing Beneficial Owners.

         Because of time zone differences, credits of securities received in
Clearstream Luxembourg 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. Such credits or any
transactions in such securities settled during such processing will be reported
to the relevant Euroclear or Clearstream Luxembourg Participants on such
business day. Cash received in Clearstream Luxembourg or Euroclear as a result
of sales of securities by or through a Clearstream Luxembourg Participant or
Euroclear Participant to a DTC Participant will be received with value on the
DTC settlement date but will be available in the relevant Clearstream Luxembourg
or Euroclear cash account only as of the business day following settlement in
DTC. For information with respect to tax documentation procedures relating to
the Certificates, refer to "Federal Income Tax Consequences -- Withholding with
Respect to Certain Foreign Investors" and "-- Backup Withholding" in the
accompanying prospectus and "Global Clearance, Settlement and Tax Documentation
Procedures -- Certain U.S. Federal Income Tax Documentation Requirements" in
Annex I hereto.

         Transfers between Participants will occur in accordance with DTC rules.
Transfers between Clearstream Luxembourg 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
Luxembourg Participants or Euroclear Participants, on the other, will be
effected in DTC in accordance with the DTC rules on behalf of the relevant
European international clearing system by the Relevant Depositary; however, such
cross market transactions will require delivery of instructions to the relevant
European international clearing system by the counterparty in such 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 Luxembourg Participants and Euroclear Participants may not
deliver instructions directly to the European Depositaries.

         DTC, which is a New York-chartered limited purpose trust company,
performs services for its participants, some of which (and/or their
representatives) own DTC. In accordance with its normal procedures, DTC is
expected to record the positions held by each DTC participant in the Book-Entry
Certificates, whether held for its own account or as a nominee for another
person. In general, beneficial ownership of Book-Entry Certificates will be
subject to the rules, regulations and procedures governing DTC and DTC
participants as in effect from time to time.

                                      S-55


         Clearstream Luxembourg is incorporated under the laws of Luxembourg as
a professional depository. Clearstream Luxembourg holds securities for its
participating organizations ("Clearstream Luxembourg Participants") and
facilitates the clearance and settlement of securities transactions between
Clearstream Luxembourg Participants through electronic book-entry changes in
accounts of Clearstream Luxembourg Participants, thereby eliminating the need
for physical movement of certificates. Transactions may be settled in
Clearstream Luxembourg in any of various currencies, including United States
dollars. Clearstream Luxembourg provides to its Clearstream Luxembourg
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally-traded securities and securities
lending and borrowing. Clearstream Luxembourg interfaces with domestic markets
in several countries. As a professional depository, Clearstream Luxembourg is
subject to regulation by the Luxembourg Monetary Institute. Clearstream
Luxembourg Participants are recognized financial institutions around the world,
including underwriters, securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. Indirect access to
Clearstream Luxembourg is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Clearstream Luxembourg Participant, either directly or
indirectly.

         Euroclear was created in 1968 to hold securities for its participants
("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
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of various 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 Euroclear Bank, S.A./N.V. (the
"Euroclear Operator"). All operations are conducted by the Euroclear Operator,
and all Euroclear securities clearance accounts and Euroclear cash accounts are
accounts with the Euroclear Operator. 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.

         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 (collectively, the "Terms and Conditions"). 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 certificates 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 on the Book-Entry Certificates will be made on each
Distribution Date by the Securities Administrator, on behalf of the Trustee to
DTC. DTC will be responsible for crediting the amount of such payments to the
accounts of the applicable DTC participants in accordance with DTC's normal
procedures. Each DTC participant will be responsible for disbursing such payment
to the Beneficial Owners of the Book-Entry Certificates that it represents and
to each

                                      S-56


Financial Intermediary for which it acts as agent. Each such Financial
Intermediary will be responsible for disbursing funds to the beneficial owners
of the Book-Entry Certificates that it represents.

         Under a book-entry format, Beneficial Owners of the Book-Entry
Certificates may experience some delay in their receipt of payments, since such
payments will be made by the Securities Administrator to Cede & Co. Payments
with respect to Certificates held through Clearstream Luxembourg or Euroclear
will be credited to the cash accounts of Clearstream Luxembourg Participants or
Euroclear Participants in accordance with the relevant system's rules and
procedures, to the extent received by the Relevant Depositary. Such payments
will be subject to tax reporting in accordance with relevant United States tax
laws and regulations. See "Federal Income Tax Consequences -- Withholding with
Respect to Certain Foreign Investors" and "-- Backup Withholding" in the
accompanying prospectus.

         Because DTC can only act on behalf of Financial Intermediaries, the
ability of a Beneficial Owner to pledge Book-Entry Certificates to persons or
entities that do not participate in the Depository system, or otherwise take
actions in respect of such Book-Entry Certificates, may be limited due to the
lack of physical certificates for such Book-Entry Certificates. In addition,
issuance of the Book-Entry Certificates in book-entry form may reduce the
liquidity of such Certificates in the secondary market since certain potential
investors may be unwilling to purchase Certificates for which they cannot obtain
physical certificates.

         Monthly and annual reports will be provided to Cede & Co., as nominee
of DTC, and may be made available by Cede & Co. to Beneficial Owners upon
request, in accordance with the rules, regulations and procedures creating and
affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Certificates of such Beneficial Owners are credited.

         DTC has advised the Trustee that, unless and until Definitive
Certificates are issued, DTC will take any action permitted to be taken by the
holders of the Book-Entry Certificates under the Agreement only at the direction
of one or more Financial Intermediaries to whose DTC accounts the Book-Entry
Certificates are credited, to the extent that such actions are taken on behalf
of Financial Intermediaries whose holdings include such Book-Entry Certificates.
Clearstream Luxembourg or the Euroclear Operator, as the case may be, will take
any other action permitted to be taken by a Certificateholder under the Pooling
and Servicing Agreement on behalf of a Clearstream Luxembourg Participant or
Euroclear Participant only in accordance with its relevant rules and procedures
and subject to the ability of the Relevant Depositary to effect such actions on
its behalf through DTC. DTC may take actions, at the direction of the related
Participants, with respect to some Book-Entry Certificates which conflict with
actions taken with respect to other Certificates.

         Although DTC, Clearstream Luxembourg and Euroclear have agreed to the
foregoing procedures in order to facilitate transfers of Book-Entry Certificates
among participants of DTC, Clearstream Luxembourg and Euroclear, they are under
no obligation to perform or continue to perform such procedures and such
procedures may be discontinued at any time.

         None of the Seller, the Depositor, the Securities Administrator, the
Master Servicer, the Servicers or the Trustee will have any responsibility for
any aspect of the records relating to or

                                      S-57


payments made on account of beneficial ownership interests of the Book-Entry
Certificates held by Cede & Co., as nominee of DTC, or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests or transfers thereof.

         Definitive Certificates will be issued to Beneficial Owners or their
nominees, respectively, rather than to DTC or its nominee, only under the
limited conditions set forth in the accompanying prospectus under "Description
of the Securities -- Book-Entry Registration of Securities." Upon the occurrence
of an event described in the penultimate paragraph thereunder, the Securities
Administrator, on behalf of the Trustee, is required to direct DTC to notify
Participants that have ownership of Book-Entry Certificates as indicated on the
records of DTC of the availability of Definitive Certificates for the Book-Entry
Certificates. Upon surrender by DTC of the Definitive Certificates representing
the Book-Entry Certificates, and upon receipt of instruction from DTC for
re-registration, the Securities Administrator, on behalf of the Trustee, will
re-issue the Book-Entry Certificates as Definitive Certificates in the
respective principal balances owned by the individual Beneficial Owner and
thereafter the Trustee will recognize the holders of such Definitive
Certificates as Certificateholders under the Pooling and Servicing Agreement.

         For a description of the procedures generally applicable to the
Book-Entry Certificates, see "Description of the Securities -- Book-Entry
Registration of Securities" in the accompanying prospectus.

PAYMENTS ON MORTGAGE LOANS; ACCOUNTS

         On or prior to the Closing Date, each Servicer will establish and
maintain or cause to be established and maintained an account or accounts for
the collection of payments on the Mortgage Loans which will be separate from
such Servicer's other assets (each, a "Custodial Account"). On or prior to the
Closing Date, the Securities Administrator will establish an account (the
"Distribution Account"), which will be maintained with the Securities
Administrator in trust for the benefit of the Certificateholders. On the 18th
day of each month (or, if such 18th day is not a Business Day, on the
immediately preceding Business Day), each Servicer will remit all amounts on
deposit in the related Custodial Account to the Distribution Account. On each
Distribution Date, to the extent of the Available Distribution Amount on deposit
in the Distribution Account, the Securities Administrator, on behalf of the
Trustee, will withdraw the Certificate Distribution Amount to pay the
Certificateholders. The "Certificate Distribution Amount" for any Distribution
Date will equal the sum of the (i) respective Interest Distribution Amounts with
respect to each class of Certificates, (ii) the related Senior Principal
Distribution Amount and (iii) the related Subordinate Principal Distribution
Amount (as each such term is defined herein).

         As further compensation, funds credited to the Custodial Account
established by each Servicer may be invested at the discretion of such Servicer
for its own benefit in Permitted Investments (as defined in the related
Servicing Agreement).

AVAILABLE DISTRIBUTION AMOUNT

         Distributions of interest and principal on the Certificates will be
made on each Distribution Date from the Available Distribution Amount of Pool 1,
in the case of the Group 1

                                      S-58


Certificates and from the Available Distribution Amount of Pool 2, in the case
of the Group 2 Certificates, in the order of priority set forth below at " --
Priority of Distributions." The "Available Distribution Amount" with respect to
each Mortgage Pool and any Distribution Date, as more fully described in the
Pooling and Servicing Agreement, will generally equal the following amounts:

                  (1) all scheduled installments of interest (net of the Master
         Servicing Fee and the Servicing Fees) and principal collected on the
         related Mortgage Loans and due during the related Due Period, together
         with any Monthly Advances in respect thereof;

                  (2) all proceeds of any primary mortgage guaranty insurance
         policies or any other insurance policies with respect to the related
         Mortgage Loans, to the extent such proceeds are not applied to the
         restoration or repair of the related mortgaged property or released to
         the related mortgagor in accordance with the Servicer's normal
         servicing procedures (collectively, "Insurance Proceeds");

                  (3) all other amounts received and retained in connection with
         the liquidation of defaulted Mortgage Loans in such Mortgage Pool, by
         foreclosure or otherwise ("Liquidation Proceeds") during the month
         preceding the month of such Distribution Date, including any Subsequent
         Recoveries, with respect to any Additional Collateral Loans in such
         Mortgage Pool, all proceeds of the related Additional Collateral, to
         the extent payable;

                  (4) all partial or full prepayments of principal, together
         with any accrued interest thereon, identified as having been received
         on the related Mortgage Loans during the calendar month immediately
         preceding the Distribution Date (the "Prepayment Period"), plus any
         amounts received from the Master Servicer or the Servicers in respect
         of Prepayment Interest Shortfalls (as defined at "-- Distributions of
         Interest") on such Mortgage Loans; and

                  (5) amounts received with respect to such Distribution Date as
         the purchase price or a price adjustment in respect of a defective
         Mortgage Loan in such Mortgage Pool purchased or replaced by the Seller
         as of such Distribution Date as a result of a breach of a
         representation or warranty or a document defect;

         minus:

         -        an amount equal to the product of (a) the applicable Pool
                  Percentage and (b) the sum of (i) all charges and other
                  amounts payable or reimbursable to the Master Servicer, the
                  Securities Administrator and the Trustee under the Pooling and
                  Servicing Agreement (subject to an aggregate maximum amount of
                  $300,000 annually to be paid to such parties collectively,
                  whether from collections from Pool 1 or Pool 2) and (ii) all
                  charges and other amounts payable to the Servicers under the

                  to the related Mortgage Loans, any unreimbursed expenses
                  incurred in connection with a liquidation or

                                      S-59


                  foreclosure and any related unreimbursed Monthly Advances or
                  servicing advances due to the Master Servicer or the
                  Servicers;

         -        with respect to the related Mortgage Loans, any unreimbursed
                  Monthly Advances or servicing advances determined to be
                  nonrecoverable; and

         -        in the case of paragraphs (1) through (4) above with respect
                  to the related Mortgage Loans, any amounts collected which are
                  determined to be attributable to a subsequent Due Period or
                  Prepayment Period.

         The "Pool Percentage" for each Mortgage Pool and any Distribution Date
will be a fraction, expressed as a percentage, the numerator of which is the
aggregate Stated Principal Balance of the Mortgage Loans in such Mortgage Pool
as of such date and the denominator of which is the sum of the aggregate Stated
Principal Balance of all of the Mortgage Loans (in the aggregate) as of such
date.

DISTRIBUTIONS OF INTEREST

         General. The "Interest Distribution Amount" on each Distribution Date
with respect to each class of Certificates, will equal the Current Interest for
that class on that Distribution Date as reduced by such class' share of Net
Interest Shortfalls (as described below).

         -        "CURRENT INTEREST" for each class of Certificates on any
                  Distribution Date will equal the amount of interest accrued
                  during the related Accrual Period on the related Class
                  Principal Amount immediately prior to that Distribution Date
                  (or, in the case of the Class 1-XA and Class 1-XB
                  Certificates, the related Class Notional Amount thereof for
                  that Distribution Date) at the applicable Certificate Interest
                  Rate.

         -        The "ACCRUAL PERIOD" applicable to the LIBOR Certificates with
                  respect to any Distribution Date, will be the period
                  commencing on the 20th day of the month immediately preceding
                  the month in which such Distribution Date occurs (or in the
                  case of the first Distribution Date, beginning on the Closing
                  Date) and ending on the 19th day of the month in which such
                  Distribution Date occurs. The "Accrual Period" applicable to
                  all other classes of Certificates will be the calendar month
                  immediately preceding the month in which the related
                  Distribution Date occurs. For each Distribution Date and each
                  related Accrual Period, interest on all classes of
                  Certificates will be calculated and payable on the basis of a
                  360-day year consisting of twelve 30-day months, except that
                  for the first Accrual Period only, interest on each class of
                  LIBOR Certificates will be calculated and payable on the basis
                  of a 21-day Accrual Period and a year assumed to consist of
                  360 days.

         -        The "CLASS PRINCIPAL AMOUNT" of each class of Certificates
                  will be equal to the aggregate Certificate Principal Amounts
                  of the Certificates of that class.

         -        The "CERTIFICATE PRINCIPAL AMOUNT" of any Offered Certificate
                  (other than a Class X Certificate) as of any Distribution Date
                  will equal its Certificate Principal Amount as of the Closing
                  Date, as reduced by all amounts previously distributed on that
                  Certificate in respect of principal and the principal portion
                  of any Realized Losses (as

                                      S-60


                  defined at "-- Allocation of Realized Losses") previously
                  allocated to that Certificate; provided, however, that on any
                  Distribution Date on which a Subsequent Recovery is
                  distributed, the Certificate Principal Amount of any class of
                  Group 1 Certificates then outstanding to which a Realized Loss
                  amount has been applied in respect of losses on the Pool 1
                  Mortgage Loans, and any class of Group 2 Certificates then
                  outstanding to which a Realized Loss amount has been applied
                  in respect of losses on the Pool 2 Mortgage Loans, as
                  applicable, will be increased, in order of seniority, by an
                  amount (to be applied pro rata to all Certificates of such
                  class) equal to (a) in the case of the holders of the Group 1
                  Certificates, the aggregate amount of any Subsequent Recovery
                  distributed on such date to such Certificateholders, after
                  application (for this purpose) to more senior classes of Group
                  1 Certificates and (b) in the case of the holders of the Group
                  2 Certificates, the aggregate amount of any Subsequent
                  Recovery distributed on such date to such Certificateholders,
                  after application (for this purpose) to more senior classes of
                  Group 2 Certificates. The Certificate Principal Amount of a
                  class of Group 1 Subordinate Certificates and Group 2
                  Subordinate Certificates may be additionally reduced by
                  allocation of any Group 1 Subordinate Certificate Writedown
                  Amount or Group 2 Subordinate Certificate Writedown Amount,
                  respectively (each, as defined at "-- Allocation of Realized
                  Losses").

         The "CLASS NOTIONAL AMOUNT" of the Class 1-XA Certificates with respect
to any Distribution Date will equal the sum of the Class Principal Amounts of
the Class 1-A1 and Class 1-A2 Certificates immediately prior to such
Distribution Date. The initial Class Notional Amount of the Class 1-XA
Certificates is $148,288,000. The "CLASS NOTIONAL AMOUNT" of the Class 1-XB
Certificates with respect to any Distribution Date will equal the sum of the
Class Principal Amounts of the Class 1-B1 and Class 1-B2 Certificates
immediately prior to such Distribution Date. The initial Class Notional Amount
of the Class 1-XB Certificates is $3,488,000.

         Net Interest Shortfalls. As described above, the Current Interest for
each class of Certificates for any Distribution Date will be reduced by the
amount of Net Interest Shortfalls experienced by the related Mortgage Pool. With
respect to any Distribution Date and any Mortgage Pool, the "NET INTEREST
SHORTFALL" is equal to the sum of:

                  -        any Net Prepayment Interest Shortfalls for that
                           Mortgage Pool and Distribution Date; and

                  -        the amount of interest that would otherwise have been
                           received with respect to any Mortgage Loan in such
                           Mortgage Pool which was subject to a reduction in the
                           amount of interest collectible as a result of
                           application of the Servicemembers Civil Relief Act,
                           as amended (the "Relief Act") or similar state or
                           local law (any such reduction, a "Relief Act
                           Reduction") (see "Certain Legal Aspects of the Loans
                           -- Servicemembers Civil Relief Act" in the
                           accompanying prospectus.

         -        "NET PREPAYMENT INTEREST SHORTFALLS" with respect to a
                  Mortgage Loan and any Distribution Date is the amount by which
                  a Prepayment Interest Shortfall for the related Due Period
                  exceeds the amount that the Master Servicer is obligated to
                  remit

                                      S-61


                  pursuant to the Pooling and Servicing Agreement and/or each
                  Servicer is obligated to remit pursuant to the applicable
                  Servicing Agreement, to cover such shortfall for such Due
                  Period.

         -        A "PREPAYMENT INTEREST SHORTFALL" with respect to a Mortgage
                  Loan and any Distribution Date is the amount by which one
                  month's interest at the applicable Mortgage Rate on a Mortgage
                  Loan as to which a voluntary prepayment in full has been made,
                  exceeds the amount of interest actually received in connection
                  with such prepayment.

         -        The "DUE PERIOD" with respect to a Mortgage Loan and any
                  Distribution Date is the period beginning on the second day of
                  the calendar month preceding the month in which such
                  Distribution Date occurs and ending on the first day of the
                  calendar month in which such Distribution Date occurs.

         On each Distribution Date, Net Interest Shortfalls for such
Distribution Date will be allocated (1) among the Group 1 Certificates
proportionately based on the amount of Current Interest otherwise distributable
on the Group 1 Certificates on such Distribution Date and (2) among the Group 2
Certificates proportionately based on the amount of Current Interest otherwise
distributable on the Group 2 Certificates on such Distribution Date.

         If on a particular Distribution Date, the Available Distribution Amount
for a Mortgage Pool applied in the order described below under "-- Priority of
Distributions" is not sufficient to make a full distribution of Current Interest
on the Certificates in the related Certificate Group (an "Interest Shortfall"),
interest will be distributed on each Certificate of equal priority within such
Certificate Group based on the pro rata amount of interest it would otherwise
have been entitled to receive in the absence of such shortfall. Any unpaid
interest amount will be carried forward and added to the amount which holders of
each such class of Certificates will be entitled to receive on the next
Distribution Date. An Interest Shortfall could occur, for example, if losses
realized on the Mortgage Loans in that Mortgage Pool were exceptionally high or
were concentrated in a particular month. Any unpaid interest amount so carried
forward will not bear interest.

         Certificate Interest Rates. The Certificate Interest Rate for each
Accrual Period for each class of Certificates is as follows:

         Group 1 Certificates:

                  (A) CERTIFICATE INTEREST RATES FOR LIBOR CERTIFICATES. The
         "Certificate Interest Rate" for each class of LIBOR Certificates will
         be the applicable annual rate described below:

                  -        CLASS 1-A1 CERTIFICATES: the least of (i) One-Month
                           LIBOR plus 0.220% (the "1-A1 Margin"), (ii) the Net
                           WAC for Pool 1 and (iii) 11.50%.

                  -        CLASS 1-A2 CERTIFICATES: the least of (i) One-Month
                           LIBOR plus 0.370% (the "1-A2 Margin"), (ii) the Net
                           WAC for Pool 1 and (iii) 11.50%.

                                      S-62


                  -        CLASS 1-B1 CERTIFICATES: the least of (i) One-Month
                           LIBOR plus 0.450% (the "1-B1 Margin"), (ii) the Net
                           WAC for Pool 1 and (iii) 11.50%.

                  -        CLASS 1-B2 CERTIFICATES: the least of (i) One-Month
                           LIBOR plus 0.630% (the "1-B2 Margin"), (ii) the Net
                           WAC for Pool 1 and (iii) 11.50%.

         As described at "-- Optional Clean-Up Redemption of the Certificates,"
if the option to sell the Mortgage Loans and redeem the Group 1 Certificates is
not exercised by the Master Servicer on the initial Pool 1 Clean-Up Call Date,
then on the immediately following Distribution Date, the 1-A1 Margin will be
increased to 0.440%, the 1-A2 Margin will be increased to 0.740%; the 1-B1
Margin will be increased to 0.675%, and the 1-B2 Margin will be increased to
0.945%, and such increased margins will remain in effect on all subsequent
Distribution Dates.

                  (B) CERTIFICATE INTEREST RATE FOR THE CLASS 1-XA CERTIFICATES.
         The "Certificate Interest Rate" applicable to the Class 1-XA
         Certificates will be a per annum rate equal to the excess, if any, of
         the Net WAC for Pool 1 over the weighted average of the Certificate
         Interest Rates of the Class 1-A1 and Class 1-A2 Certificates (for the
         first Distribution Date only, adjusted to reflect the actual number of
         days in the Accrual Period).

         Notwithstanding the foregoing, on each Distribution Date, the Interest
Distribution Amount that would otherwise be distributable to the holders of the
Class 1-XA Certificates, based on the applicable Certificate Interest Rate
described above, may be reduced by the amount, if any, that is necessary to fund
payment of any Net WAC Shortfalls to the holders of the Class 1-A1 and Class
1-A2 Certificates (See "-- Reserve Fund" below). The holders of the Class 1-XA
Certificates will not be reimbursed for amounts distributed from the Reserve
Fund to the Class 1-A1 or Class 1-A2 Certificates.

                  (C) CERTIFICATE INTEREST RATE FOR THE CLASS 1-XB CERTIFICATES.
         The "Certificate Interest Rate" applicable to the Class 1-XB
         Certificates will be a per annum rate equal to the excess, if any, of
         the Net WAC for Pool 1 over the weighted average of the Certificate
         Interest Rates of the Class 1-B1 and Class 1-B2 Certificates (for the
         first Distribution Date only, adjusted to reflect the actual number of
         days in the Accrual Period).

         Notwithstanding the foregoing, on each Distribution Date, the Interest
Distribution Amount that would otherwise be distributable to the holders of the
Class 1-XB Certificates, based on the applicable Certificate Interest Rate
described above, may be reduced by the amount, if any, that is necessary to fund
payment of any Net WAC Shortfalls to the holders of the Class 1-B1 and Class
1-B2 Certificates (See "-- Reserve Fund" below). The holders of the Class 1-XB
Certificates will not be reimbursed for amounts distributed from the Reserve
Fund to the Class 1-B1 or Class 1-B2 Certificates.

                  (D) CERTIFICATE INTEREST RATES FOR THE CLASS 1-AR, CLASS 1-B3,
         CLASS 1-B4, CLASS 1-B5, CLASS 1-B6 AND CLASS 1-LTR CERTIFICATES. The
         Certificate Interest Rate applicable to each of the Class 1-AR, Class
         1-B3, Class 1-B4, Class 1-B5 and Class 1-B6

                                      S-63


         Certificates will equal the Net WAC for Pool 1. The Class 1-LTR
         Certificate will not have a Certificate Interest Rate.

         Group 2 Certificates:

         CERTIFICATE INTEREST RATES FOR GROUP 2 CERTIFICATES. The Certificate
Interest Rate applicable to each of the Class 2-A1, Class 2-A2, Class 2-AR,
Class 2-B1, Class 2-B2, Class 2-B3, Class 2-B4, Class 2-B5 and Class 2-B6
Certificates will equal the Net WAC for Pool 2.

         Definitions Related to Pool 1 and Pool 2:

                  -        The "NET WAC" with respect to any Mortgage Pool and
                           any Distribution Date will be the weighted average of
                           the Net Mortgage Rates of the Mortgage Loans in the
                           related Mortgage Pool as of the Due Date of the
                           calendar month immediately preceding the calendar
                           month of such Distribution Date, weighted on the
                           basis of their Stated Principal Balances.

                  -        The "MORTGAGE RATE" with respect to any Mortgage Loan
                           is the annual rate of interest borne by the related
                           mortgage note from time to time, as of the related
                           due date.

                  -        The "NET MORTGAGE RATE" as to any Mortgage Loan and
                           any Distribution Date will equal the Mortgage Rate,
                           reduced by the related Expense Rate.

                  -        The "EXPENSE RATE" as to each Mortgage Loan is equal
                           to the sum of the Master Servicing Fee Rate, the
                           applicable Servicing Fee Rate and the rate of premium
                           on any lender paid mortgage insurance policies.

                  -        The "STATED PRINCIPAL BALANCE" of a Mortgage Loan at
                           any Due Date is equal to the unpaid principal balance
                           of such Mortgage Loan as of such Due Date as
                           specified in the amortization schedule at the time
                           relating thereto (before any adjustment to such
                           amortization schedule by reason of any moratorium or
                           similar waiver or grace period) after giving effect
                           to any previous principal prepayments and Liquidation
                           Proceeds allocable to principal and to the payment of
                           principal due on such Due Date and irrespective of
                           any delinquency in payment by the related mortgagor.

                  -        The "DUE DATE" of a Mortgage Loan is the date
                           specified in the related Mortgage Note on which the
                           monthly scheduled payment of interest and principal
                           (or interest only during any applicable interest-only
                           period following origination) is due, which is the
                           first day of the calendar month in the case of the
                           Mortgage Loans.

         Net WAC Shortfalls. For any class of LIBOR Certificates and any
Distribution Date, the "Net WAC Shortfall" for such class will equal the sum of:

      (i)   the excess, if any, of an amount that would have been the Current
            Interest for such class if the Certificate Interest Rate for such
            class were calculated without regard to

                                      S-64


            clause (ii) in the definition thereof, over the actual Current
            Interest for such class for such Distribution Date;

      (ii)  any excess described in clause (i) above remaining unpaid from prior
            Distribution Dates; and

      (iii) interest for the applicable Accrual Period on the amount described
            in clause (ii) above based on the applicable Certificate Interest
            Rate (determined without regard to clause (ii) in the definition
            thereof).

         Reserve Fund. Pursuant to the terms of the Pooling and Servicing
Agreement, the Securities Administrator will establish an account (the "Reserve
Fund"), which will be held in trust by the Securities Administrator on behalf of
the holders of the LIBOR Certificates and the Class 1-XA and Class 1-XB
Certificates. For federal income tax purposes, the Reserve Fund will not be an
asset of any REMIC. The Reserve Fund will be the sole source of payments to the
holders of the LIBOR Certificates with respect to any Net WAC Shortfalls on such
Certificates.

         The Reserve Fund will comprise two sub accounts: the "Class 1-XA Sub
Account," and the "Class 1-XB Sub Account" (each, a "Sub Account"). On each
Distribution Date, (i) Current Interest that would otherwise be distributable
with respect to the Class 1-XA Certificates will be deposited instead in the
Reserve Fund and credited to the Class 1-XA Sub Account and (ii) Current
Interest that would otherwise be distributable with respect to the Class 1-XB
Certificates will be deposited instead in the Reserve Fund and credited to the
Class 1-XB Sub Account, in each case, to the extent of the applicable "Required
Reserve Fund Deposit" for such class in the manner described below.

         For any Distribution Date, the "Required Reserve Fund Deposit" for the
Class 1-XA Certificates will be an amount equal to the lesser of (i) the Current
Interest for the Class 1-XA Certificates for such Distribution Date and (ii) the
amount required to bring the balance of the Class 1-XA Sub Account up to an
amount equal to the sum of (a) the Net WAC Shortfalls for such Distribution Date
with respect to the Class 1-A1 and Class 1-A2 Certificates and (b) $5,000.

         For any Distribution Date, the "Required Reserve Fund Deposit" for the
Class 1-XB Certificates will be an amount equal to the lesser of (i) the Current
Interest for the Class 1-XB Certificates for such Distribution Date and (ii) the
amount required to bring the balance of the Class 1-XB Sub Account up to an
amount equal to the sum of (a) the Net WAC Shortfalls for such Distribution Date
with respect to the Class 1-B1 and Class 1-B2 Certificates and (b) $5,000.

         The holders of the Class 1-XA and Class 1-XB Certificates will not be
entitled to reimbursement for any related Required Reserve Fund Deposit.

         For any Distribution Date, the Securities Administrator will deposit
into the Reserve Fund and credit to the appropriate Sub Account of the Reserve
Fund, any Required Reserve Fund Deposit for such date.

         On any Distribution Date for which a Net WAC Shortfall exists with
respect to the Class 1-A1 or Class 1-A2 Certificates, the Securities
Administrator will withdraw from the Reserve

                                      S-65


Fund and debit to the Class 1-XA Sub Account, the amount of such Net WAC
Shortfall for distribution on such Distribution Date as described herein under
"--Priority of Distributions."

         On any Distribution Date for which a Net WAC Shortfall exists with
respect to the Class 1-B1 or Class 1-B2 Certificates, the Securities
Administrator will withdraw from the Reserve Fund and debit to the Class 1-XB
Sub Account the amount of such Net WAC Shortfall for distribution on such
Distribution Date as described herein under "--Priority of Distributions."

         If, immediately after any Distribution Date, the amount credited to any
Sub Account of the Reserve Fund exceeds the initial credit thereto, the
Securities Administrator will distribute such excess from the Reserve Fund to
the holders of the Certificates for which such amounts were credited to the
relevant Sub Account.

         Determination of LIBOR. With respect to the LIBOR Certificates, on the
second LIBOR Business Day preceding the commencement of each Accrual Period
(each such date, a "One-Month LIBOR Determination Date"), the Securities
Administrator will determine One-Month LIBOR based on the "Interest Settlement
Rate" for U.S. dollar deposits of one-month maturity set by the British Bankers'
Association (the "BBA") as of 11:00 a.m. (London time) on the One-Month LIBOR
Determination Date.

         The BBA's Interest Settlement Rates are currently displayed on the Dow
Jones Telerate Service page 3750 (such page, or such other page as may replace
page 3750 on that service or such other service as may be nominated by the BBA
as the information vendor for the purpose of displaying the BBA's Interest
Settlement Rates for deposits in U.S. dollars, the "Designated Telerate Page").
Such Interest Settlement Rates are also currently available on Reuters Monitor
Money Rates Service page "LIBOR01" and Bloomberg L.P. page "BBAM." The BBA's
Interest Settlement Rates currently are rounded to five decimal places.

         A "LIBOR Business Day" is any day on which banks in London and New York
are open for conducting transactions in foreign currency and exchange.

         With respect to any One-Month LIBOR Determination Date, if the BBA's
Interest Settlement Rate does not appear on the Designated Telerate Page as of
11:00 a.m. (London time) on such date, or if the Designated Telerate Page is not
available on such date, the Securities Administrator will obtain such rate from
the Reuters or Bloomberg page. If either such rate is not published for the
applicable One-Month LIBOR Determination Date, One-Month LIBOR for such date
will be the most recently published Interest Settlement Rate. In the event that
the BBA no longer sets an Interest Settlement Rate for One-Month LIBOR, the
Securities Administrator will designate an alternative index that has performed,
or that the Securities Administrator expects to perform, in a manner
substantially similar to the BBA's Interest Settlement Rate for One-Month LIBOR.
The Securities Administrator will select a particular index as the alternative
index only if it receives an opinion of counsel (furnished at the Trust Fund's
expense) that the selection of such index will not cause any REMIC to lose its
classification as a REMIC for federal income tax purposes.

         The establishment of One-Month LIBOR on each One-Month LIBOR
Determination Date by the Securities Administrator and the Securities
Administrator's calculation of the

                                      S-66


Certificate Interest Rate applicable to each class of LIBOR Certificates for the
related Accrual Period will (in the absence of manifest error) be final and
binding.

         Notwithstanding the foregoing, One-Month LIBOR for the first
Distribution Date will be determined two Business Days prior to the Closing
Date.

DISTRIBUTIONS OF PRINCIPAL

         On each Distribution Date, the Available Distribution Amount for each
Mortgage Pool remaining after the payment of the applicable Interest
Distribution Amount for the related Certificate Group, up to the amount of the
Senior Principal Distribution Amount for such Mortgage Pool, will be distributed
as principal on the Senior Certificates.

         -        The "SENIOR PRINCIPAL DISTRIBUTION AMOUNT" with respect to
                  each of the Group 1 Senior Certificates and the Group 2 Senior
                  Certificates and any Distribution Date is equal to the sum of:

                        (1) the product of (a) the related Senior Percentage and
         (b) the principal portion of each Scheduled Payment on each Mortgage
         Loan in the related Mortgage Pool due during the related Due Period;

                        (2) the product of (a) the related Senior Prepayment
         Percentage and (b) each of the following amounts: (i) the principal
         portion of each full and partial principal prepayment made by a
         borrower on a Mortgage Loan in the related Mortgage Pool during the
         related Prepayment Period; (ii) each other unscheduled collection,
         including Subsequent Recoveries, Insurance Proceeds and net Liquidation
         Proceeds (other than with respect to any Mortgage Loan in the related
         Mortgage Pool that was finally liquidated during the related Prepayment
         Period) representing or allocable to recoveries of principal of the
         related Mortgage Loans received during the related Prepayment Period;
         and (iii) the principal portion of the purchase price of each Mortgage
         Loan in the purchased by the Seller or any other person pursuant to the
         Mortgage Loan Purchase Agreement due to a defect in documentation or a
         material breach of a representation and warranty with respect to such
         Mortgage Loan or, in the case of a permitted substitution of a
         defective Mortgage Loan in the related Mortgage Pool, the amount
         representing any principal adjustment in connection with any such
         replaced Mortgage Loan in the related Mortgage Pool with respect to the
         related Prepayment Period;

                        (3) with respect to unscheduled recoveries allocable to
         principal of any Mortgage Loan in the related Mortgage Pool that was
         fully liquidated during the related Prepayment Period, the lesser of
         (a) the net Liquidation Proceeds allocable to principal and (b) the
         product of (i) the related Senior Prepayment Percentage for that date
         and (ii) the related remaining Stated Principal Balance of the related
         Mortgage Loan at the time of liquidation; and

                        (4) any amounts described in clauses (1) through (3)
         above that remain unpaid with respect to the Senior Certificates of
         such Certificate Group from prior Distribution Dates.

                                      S-67


         -        A "SCHEDULED PAYMENT" with respect to a Mortgage Loan means
                  the scheduled monthly payment on a Mortgage Loan on any Due
                  Date allocable to principal or interest which, unless
                  otherwise specified in the related Servicing Agreement, will
                  give effect to any related debt service reduction and any
                  related deficient valuation that is ordered by a court in
                  bankruptcy and that has the effect of reducing the monthly
                  payment due on such Mortgage Loan.

         -        Except as provided below, the "SENIOR PERCENTAGE" for Pool 1
                  and any Distribution Date occurring prior to the Distribution
                  Date in October 2015 is 100%. For any Distribution Date (i)
                  occurring before the Distribution Date in October 2015 but in
                  or after October 2008 on which the "Two Times Test" for Pool 1
                  is satisfied or (ii) in or after October 2015, the Senior
                  Percentage for Pool 1 will be the related "Pro Rata Senior
                  Percentage." For any Distribution Date occurring prior to
                  October 2008 on which the Two Times Test for Pool 1 is
                  satisfied, the Senior Percentage for Pool 1 will be equal to
                  the related Pro Rata Senior Percentage plus 50% of an amount
                  equal to 100% minus the related Pro Rata Senior Percentage.
                  With respect to any Distribution Date after the aggregate
                  Class Principal Amount of the Group 1 Senior Certificates has
                  been reduced to zero, the Senior Percentage for Pool 1 will be
                  0%. Since approximately 84.43% of the Pool 1 Mortgage Loans
                  provide for payments solely of interest (and not scheduled
                  principal) for the first five or ten years following the
                  Cut-off Date, holders of the Group 1 Senior Certificates are
                  not expected to receive any payments of scheduled principal
                  during this five- or ten-year period with respect to these
                  Mortgage Loans, notwithstanding the above calculation of the
                  Senior Percentage for Pool 1.

         -        Except as provided below, the "SENIOR PERCENTAGE" for Pool 2
                  and any Distribution Date occurring prior to the Distribution
                  Date in October 2012 is 100%. For any Distribution Date (i)
                  occurring before the Distribution Date in October 2012 but in
                  or after October 2008 on which the "Two Times Test" for Pool 2
                  is satisfied or (ii) in or after October 2012, the Senior
                  Percentage for Pool 2 will be the related "Pro Rata Senior
                  Percentage." For any Distribution Date occurring prior to
                  October 2008 on which the Two Times Test for Pool 2 is
                  satisfied, the Senior Percentage for Pool 2 will be equal to
                  the related Pro Rata Senior Percentage plus 50% of an amount
                  equal to 100% minus the related Pro Rata Senior Percentage.
                  With respect to any Distribution Date after the aggregate
                  Class Principal Amount of the Group 2 Senior Certificates has
                  been reduced to zero, the Senior Percentage for Pool 2 will be
                  0%. Since approximately 60.75% of the Pool 2 Mortgage Loans
                  provide for payments solely of interest (and not scheduled
                  principal) for the first five years following origination,
                  holders of the Group 2 Senior Certificates are not expected to
                  receive any payments of scheduled principal during the first
                  five-year period with respect to these interest-only Mortgage
                  Loans, notwithstanding the above calculation of the Senior
                  Percentage for Pool 2.

         -        The "TWO TIMES TEST" with respect to any Mortgage Pool will be
                  satisfied on any Distribution Date if all the following
                  conditions are met:

                                      S-68


         -        the Aggregate Subordinate Percentage for such Mortgage Pool is
                  at least two times the Aggregate Subordinate Percentage of
                  such Mortgage Pool as of the Closing Date;

         -        the condition described in clause first of the definition of
                  "Pool 1 Step-Down Test" or "Pool 2 Step-Down Test" (described
                  below), as applicable, is satisfied for such Mortgage Pool;
                  and

         -        on or prior to the Distribution Date in September 2008,
                  cumulative Realized Losses with respect to the related
                  Mortgage Loans do not exceed 20% of the aggregate Class
                  Principal Amount of the Subordinate Certificates of the
                  related Certificate Group as of the Closing Date and on or
                  after the Distribution Date in October 2008, cumulative
                  Realized Losses with respect to the related Mortgage Loans do
                  not exceed 30% of the aggregate Class Principal Amount of the
                  Subordinate Certificates of the related Certificate Group as
                  of the Closing Date.

- -        The "AGGREGATE SUBORDINATE PERCENTAGE" with respect to any Mortgage
         Pool for any Distribution Date is the percentage equivalent of a
         fraction, the numerator of which is the aggregate Class Principal
         Amount of the Subordinate Certificates of the related Certificate
         Group, determined immediately prior to that date, and the denominator
         of which is the aggregate Stated Principal Balance of all Mortgage
         Loans in that Mortgage Pool and for such Distribution Date.

- -        The "PRO RATA SENIOR PERCENTAGE" for each Distribution Date and each
         Mortgage Pool is the percentage equivalent of a fraction, the numerator
         of which is the aggregate Class Principal Amount of the class or
         classes of Senior Certificates of the related Certificate Group
         immediately prior to such Distribution Date, and the denominator of
         which is the aggregate Stated Principal Balance of all Mortgage Loans
         in that Mortgage Pool and for such Distribution Date.

- -        The "SENIOR PREPAYMENT PERCENTAGE" with respect to Pool 1 any
         Distribution Date occurring before the Distribution Date in October
         2015 is 100%. Thereafter, the Senior Prepayment Percentage for Pool 1
         will be subject to gradual reduction as described in the following
         paragraphs. This disproportionate allocation of unscheduled payments of
         principal to the Group 1 Senior Certificates will have the effect of
         accelerating the amortization of such Senior Certificates while, in the
         absence of Realized Losses, increasing the interest in the principal
         balance of the Pool 1 Mortgage Loans evidenced by the Group 1
         Subordinate Certificates. Increasing the interest of the Group 1
         Subordinate Certificates relative to that of the Group 1 Senior
         Certificates is intended to preserve the availability of the
         subordination provided by the Group 1 Subordinate Certificates.

The Senior Prepayment Percentage for Pool 1 and any Distribution Date occurring
in or after October 2015, will be as follows:

                                      S-69


            -     for any Distribution Date occurring in or after October 2015
                  but before October 2016, the Senior Percentage for Pool 1 plus
                  70% of the related Subordinate Percentage for that date;

            -     for any Distribution Date occurring in or after October 2016
                  but before October 2017, the Senior Percentage for Pool 1 plus
                  60% of the related Subordinate Percentage for that date;

            -     for any Distribution Date occurring in or after October 2017
                  but before October 2018, the Senior Percentage for Pool 1 plus
                  40% of the related Subordinate Percentage for that date;

            -     for any Distribution Date occurring in or after October 2018
                  but before October 2019, the Senior Percentage for Pool 1 plus
                  20% of the related Subordinate Percentage for that date; and

            -     for any Distribution Date occurring in October 2019 or
                  thereafter, the Senior Percentage for Pool 1 for that date.

      Notwithstanding the preceding paragraphs, no decrease in the Senior
Prepayment Percentage for Pool 1 will occur as described above unless the Pool 1
Step-Down Test is satisfied on such Distribution Date.

      As to any Distribution Date and Pool 1, the "POOL 1 STEP-DOWN TEST" will
be satisfied if both of the following conditions are met:

            first, the outstanding principal balance of all Pool 1 Mortgage
      Loans that are delinquent 60 days or more (including Mortgage Loans in
      foreclosure, REO property or bankruptcy status), averaged over the
      preceding six-month period, as a percentage of the aggregate Class
      Principal Amounts (without giving effect to any distributions on such
      Distribution Date) of the Group 1 Subordinate Certificates on such
      Distribution Date does not equal or exceed 50%; and

            second, cumulative Realized Losses on the Pool 1 Mortgage Loans do
      not exceed:

                  -     for each Distribution Date occurring in the period from
                        October 2015 to September 2016, 30% of the aggregate
                        Class Principal Amount of the Group 1 Subordinate
                        Certificates as of the Closing Date (the "Original Group
                        1 Subordinate Class Principal Amount");

                  -     for each Distribution Date occurring in the period from
                        October 2016 to September 2017, 35% of the Original
                        Group 1 Subordinate Class Principal Amount;

                  -     for each Distribution Date occurring in the period from
                        October 2017 to September 2018, 40% of the Original
                        Group 1 Subordinate Class Principal Amount;

                                      S-70



                  -     for each Distribution Date occurring in the period from
                        October 2018 to September 2019, 45% of the Original
                        Group 1 Subordinate Class Principal Amount; and

                  -     for the Distribution Date in October 2019 and
                        thereafter, 50% of the Original Group 1 Subordinate
                        Class Principal Amount.

      Notwithstanding the preceding paragraphs, if on any Distribution Date, the
Two Times Test for Pool 1 is satisfied, the Senior Prepayment Percentage for
Pool 1 will equal the Senior Percentage for Pool 1 for such Distribution Date.
However, if on any Distribution Date occurring on or after the Distribution Date
in October 2015, the Pro Rata Senior Percentage for Pool 1 exceeds the Pro Rata
Senior Percentage for Pool 1 determined on the Closing Date, the Senior
Prepayment Percentage for Pool 1 for that date will once again equal 100%.

      If on any Distribution Date, the allocation to the Group 1 Senior
Certificates entitled to distributions of principal of related full and partial
principal prepayments and other amounts in the percentage required above would
reduce the sum of the Class Principal Amounts of the Group 1 Senior Certificates
below zero, distributions in respect of principal to the Group 1 Senior
Certificates will be limited to the percentage necessary to reduce the Class
Principal Amounts of the Group 1 Senior Certificates to zero on such
Distribution Date.

      -     The "SENIOR PREPAYMENT PERCENTAGE" with respect to Pool 2 and any
            Distribution Date occurring before the Distribution Date in October
            2012 is 100%. Thereafter, the Senior Prepayment Percentage for Pool
            2 will be subject to gradual reduction as described in the following
            paragraphs. This disproportionate allocation of unscheduled payments
            of principal to the Group 2 Senior Certificates will have the effect
            of accelerating the amortization of such Senior Certificates while,
            in the absence of Realized Losses, increasing the interest in the
            principal balance of the Pool 2 Mortgage Loans evidenced by the
            Group 2 Subordinate Certificates. Increasing the interest of the
            Group 2 Subordinate Certificates relative to that of the Group 2
            Senior Certificates is intended to preserve the availability of the
            subordination provided by the Group 2 Subordinate Certificates.

      The "Senior Prepayment Percentage" for Pool 2 and any Distribution Date
      occurring in or after October 2012, will be as follows:

                  -     for any Distribution Date occurring in or after October
                        2012 but before October 2013, the Senior Percentage for
                        Pool 2 plus 70% of the related Subordinate Percentage
                        for that date;

                  -     for any Distribution Date occurring in or after October
                        2013 but before October 2014, the Senior Percentage for
                        Pool 2 plus 60% of the related Subordinate Percentage
                        for that date;

                  -     for any Distribution Date occurring in or after October
                        2014 but before October 2015, the Senior Percentage for
                        Pool 2 plus 40% of the related Subordinate Percentage
                        for that date;

                                      S-71



            -     for any Distribution Date occurring in or after October 2015
                  but before October 2016, the Senior Percentage for Pool 2 plus
                  20% of the related Subordinate Percentage for that date; and

            -     for any Distribution Date occurring in October 2016 or
                  thereafter, the Senior Percentage for Pool 2 for that date.

      Notwithstanding the preceding paragraphs, no decrease in the Senior
Prepayment Percentage for Pool 2 will occur as described above unless the Pool 2
Step-Down Test is satisfied on such Distribution Date.

      As to any Distribution Date and Pool 2, the "POOL 2 STEP-DOWN TEST" will
be satisfied if both of the following conditions are met:

            first, the outstanding principal balance of all Pool 2 Mortgage
      Loans that are delinquent 60 days or more (including Mortgage Loans in
      foreclosure, REO property or bankruptcy status), averaged over the
      preceding six-month period, as a percentage of the aggregate Class
      Principal Amounts (without giving effect to any distributions on such
      Distribution Date) of the Group 2 Subordinate Certificates on such
      Distribution Date does not equal or exceed 50%; and

            second, cumulative Realized Losses on the Pool 2 Mortgage Loans do
      not exceed:

                  -     for each Distribution Date occurring in the period from
                        October 2005 to September 2008, 20% of the aggregate
                        Class Principal Amount of the Group 2 Subordinate
                        Certificates as of the Closing Date (the "Original Group
                        2 Subordinate Class Principal Amount");

                  -     for each Distribution Date occurring in the period from
                        October 2008 to September 2013, 30% of the Original
                        Group 2 Subordinate Class Principal Amount;

                  -     for each Distribution Date occurring in the period from
                        October 2013 to September 2014, 35% of the Original
                        Group 2 Subordinate Class Principal Amount;

                  -     for each Distribution Date occurring in the period from
                        October 2014 to September 2015, 40% of the Original
                        Group 2 Subordinate Class Principal Amount;

                  -     for each Distribution Date occurring in the period from
                        October 2015 to September 2016, 45% of the Original
                        Group 2 Subordinate Class Principal Amount;

                  -     for the Distribution Date in October 2016 and
                        thereafter, 50% of the Original Group 2 Subordinate
                        Class Principal Amount.

      Notwithstanding the preceding paragraphs, if on any Distribution Date, the
Two Times Test for Pool 2 is satisfied, the Senior Prepayment Percentage for
Pool 2 will equal the Senior

                                      S-72



Percentage for Pool 2 for such Distribution Date. However, if on any
Distribution Date occurring on or after the Distribution Date in October 2012,
the Pro Rata Senior Percentage for Pool 2 exceeds the Pro Rata Senior Percentage
for Pool 2 determined on the Closing Date, the Senior Prepayment Percentage for
Pool 2 for that date will once again equal 100%.

      If on any Distribution Date, the allocation to the Group 2 Senior
Certificates entitled to distributions of principal of related full and partial
principal prepayments and other amounts in the percentage required above would
reduce the sum of the Class Principal Amounts of the Group 2 Senior Certificates
below zero, distributions in respect of principal to the Group 2 Senior
Certificates will be limited to the percentage necessary to reduce the Class
Principal Amounts of the Group 2 Senior Certificates to zero on such
Distribution Date.

      Subordinate Principal Distribution Amount: The Group 1 Subordinate
Certificates will be entitled to receive on each Distribution Date, from the
Available Distribution Amount for Pool 1 remaining after the payment of interest
and principal to the Group 1 Senior Certificates and any Group 1 Subordinate
Certificates ranking higher priority as described at "-- Priority of
Distributions," first, payments in respect of interest and, second, the pro rata
share of the Subordinate Principal Distribution Amount, in accordance with the
priorities set forth under "-- Priority of Distributions."

      Notwithstanding the foregoing, if on any Distribution Date, with respect
to any class of Group 1 Subordinate Certificates, the sum of the Class
Subordination Percentage of such class and the aggregate Class Subordination
Percentages of all classes of Group 1 Subordinate Certificates which have higher
numerical class designations than such class is less than the Applicable Credit
Support Percentage for such class on the date of issuance of the Certificates,
no distribution of principal prepayments will be made to those classes of
Subordinate Certificates, and the amount otherwise distributable to such classes
in respect of principal prepayments will be allocated among the remaining
classes of Group 1 Subordinate Certificates, pro rata, based upon their
respective Class Principal Amounts, and distributed in accordance with the
priorities set forth under "-- Priority of Distributions."

      The Group 2 Subordinate Certificates will be entitled to receive on each
Distribution Date, from the Available Distribution Amount for Pool 2 remaining
after the payment of interest and principal to the Group 2 Senior Certificates
and any Group 2 Subordinate Certificates ranking higher priority as described at
"-- Priority of Distributions," first, payments in respect of interest and,
second, the pro rata share of the Subordinate Principal Distribution Amount, in
accordance with the priorities set forth under "-- Priority of Distributions."

      Notwithstanding the foregoing, if on any Distribution Date, with respect
to any class of Group 2 Subordinate Certificates, the sum of the Class
Subordination Percentage of such class and the aggregate Class Subordination
Percentages of all classes of Group 2 Subordinate Certificates which have higher
numerical class designations than such class is less than the Applicable Credit
Support Percentage for such class on the date of issuance of the Certificates,
no distribution of principal prepayments will be made to those classes of
Subordinate Certificates, and the amount otherwise distributable to such classes
in respect of principal prepayments will be allocated among the remaining
classes of Group 2 Subordinate Certificates, pro rata, based upon their
respective Class Principal Amounts, and distributed in accordance with the
priorities set forth under "-- Priority of Distributions."

                                      S-73



      -     The "APPLICABLE CREDIT SUPPORT PERCENTAGE" for each class of
            Subordinate Certificates of a Certificate Group and any Distribution
            Date will equal the sum of the Class Subordination Percentages of
            that class and the aggregate Class Subordination Percentage of all
            other classes of Subordinate Certificates related to such
            Certificate Group having higher numerical class designations than
            that class.

      -     The "CLASS SUBORDINATION PERCENTAGE" for any Distribution Date and
            each class of Subordinate Certificates of a Certificate Group will
            equal a fraction (expressed as a percentage), the numerator of which
            is the Class Principal Amount of that class immediately before that
            Distribution Date and the denominator of which is the aggregate
            Class Principal Amount of all classes of Certificates related to
            such Certificate Group immediately before that Distribution Date.

      The approximate original Applicable Credit Support Percentages for the
Group 1 Subordinate Certificates on the date of issuance of such Certificates
are expected to be as follows:


                               
Class 1-B1....................    4.35%
Class 1-B2....................    3.00%
Class 1-B3....................    2.10%


      The approximate original Applicable Credit Support Percentages for the
Group 2 Subordinate Certificates on the date of issuance of such Certificates
are expected to be as follows:


                               
Class 2-B1....................    2.10%
Class 2-B2....................    1.10%
Class 2-B3....................    0.70%


      -     The "SUBORDINATE PRINCIPAL DISTRIBUTION AMOUNT" for any Mortgage
            Pool and for each Distribution Date is equal to the sum of:

            (1) the product of (a) the related Subordinate Percentage and (b)
      the principal portion of each related Scheduled Payment on each Mortgage
      Loan in the related Mortgage Pool due during the related Due Period;

            (2) the product of (a) the related Subordinate Prepayment Percentage
      and (b) each of the following amounts: (i) the principal portion of each
      full and partial principal prepayment made by a borrower on a Mortgage
      Loan in the related Mortgage Pool during the related Prepayment Period,
      (ii) each other unscheduled collection, including Subsequent Recoveries,
      Insurance Proceeds and net Liquidation Proceeds (other than with respect
      to any Mortgage Loan in the related Mortgage Pool that was finally
      liquidated during the related Prepayment Period), representing or
      allocable to recoveries of principal of Mortgage Loans in the related
      Mortgage Pool received during the related Prepayment Period and (iii) the
      principal portion of the purchase price of each Mortgage Loan in the
      related Mortgage Pool that was purchased by the Seller or any other person
      pursuant to the Mortgage Loan Purchase Agreement due to a defect in
      documentation or

                                      S-74



      a material breach of a representation or warranty with respect to such
      Mortgage Loan or, in the case of a permitted substitution of a defective
      Mortgage Loan in the related Mortgage Pool, the amount representing any
      principal adjustment in connection with any such replaced Mortgage Loan in
      the related Mortgage Pool with respect to such Distribution Date;

            (3) with respect to unscheduled recoveries allocable to principal of
      any Mortgage Loan in the related Mortgage Pool that was finally liquidated
      during the related Prepayment Period, the related net Liquidation Proceeds
      allocable to principal, to the extent not distributed pursuant to clause
      (3) of the definition of Senior Principal Distribution Amount); and

            (4) any amounts described in clauses (1) through (3) for any
      previous Distribution Date that remain unpaid;

      -     The "SUBORDINATE CLASS PERCENTAGE" for each class of Subordinate
            Certificates of a Certificate Group and each Distribution Date is
            equal to the percentage obtained by dividing the Class Principal
            Amount of such class immediately prior to such Distribution Date by
            the aggregate Class Principal Amount of all classes of Subordinate
            Certificates of such Certificate Group immediately prior to such
            date.

      -     The "SUBORDINATE PREPAYMENT PERCENTAGE" for any Distribution Date
            and for any Mortgage Pool is the difference between 100% and the
            related Senior Prepayment Percentage for Mortgage Pool on such
            Distribution Date.

      -     The "SUBORDINATE PERCENTAGE" with respect to each Mortgage Pool and
            any Distribution Date will be equal to the difference between 100%
            and the related Senior Percentage for such Mortgage Pool on such
            Distribution Date.

PRIORITY OF DISTRIBUTIONS

      The Available Distribution Amount for each Mortgage Pool will be
distributed on each Distribution Date, concurrently, as follows:

SUBORDINATION OF THE PAYMENT OF THE SUBORDINATE CERTIFICATES

      The rights of the holders of the Group 1 Subordinate Certificates to
receive distributions with respect to the Pool 1 Mortgage Loans will be
subordinated, to the extent described herein, to such rights of the holders of
each class of Group 1 Senior Certificates (and the Class X Certificates solely
with respect to interest) having a higher priority of distribution, as described
under "-- Priority of Distributions." The rights of the holders of the Group 2
Subordinate Certificates to receive distributions with respect to the Pool 2
Mortgage Loans will be subordinated, to the extent described herein, to such
rights of the holders of each class of Group 2 Senior Certificates having a
higher priority of distribution, as described under "-- Priority of
Distributions." This subordination is intended to enhance the likelihood of
regular receipt by holders of Offered Certificates having a higher priority of
distribution of the full amount of interest and principal distributable thereon,
and to afford such Certificateholders limited protection against Realized Losses
with respect to the related Mortgage Loans.

      The limited protection afforded to holders of the Senior Certificates by
means of the subordination of the Group 1 Subordinate Certificates (in the case
of the Group 1 Senior Certificates) and the Group 2 Subordinate Certificates (in
the case of the Group 2 Senior Certificates) having a lower priority of
distribution will be accomplished by the preferential right of holders of such
Offered Certificates to receive, prior to any distribution in respect of
interest or principal being made on any Distribution Date in respect of
Certificates having a lower priority of distribution, the amounts of interest
due them and principal available for distribution, respectively, on such
Distribution Date.

ALLOCATION OF REALIZED LOSSES

      If a Realized Loss occurs on the Pool 1 Mortgage Loans, then, on each
Distribution Date the principal portion of that Realized Loss will be allocated
first, to reduce the Class Principal Amount of each class of Group 1 Subordinate
Certificates, in inverse order of priority, until the Class Principal Amount
thereof has been reduced to zero (that is, such Realized Losses will be
allocated to the Class 1-B6 Certificates while those Certificates are
outstanding, then to the Class 1-B5 Certificates, and so forth) and second, pro
rata, to the Group 1 Senior Certificates, on the basis of their respective
Certificate Principal Amounts; provided, however, that the amount of losses
calculated above that would otherwise reduce the Class Principal Amount of the
Class 1-A1 Certificates will first reduce the Class Principal Amount of the
Class 1-A2 Certificates until the Class Principal Amount of the Class 1-A2
Certificates has been reduced to zero, before reducing the Class Principal
Amount of the Class 1-A1 Certificates.

      If a Realized Loss occurs on the Pool 2 Mortgage Loans, then, on each
Distribution Date the principal portion of that Realized Loss will be allocated
first, to reduce the Class Principal Amount of each class of Group 2 Subordinate
Certificates, in inverse order of priority, until the Class Principal Amount
thereof has been reduced to zero (that is, such Realized Losses will be
allocated to the Class 2-B6 Certificates while those Certificates are
outstanding, then to the Class 2-B5 Certificates, and so forth) and second, pro
rata, to the Group 2 Senior Certificates, on the basis of their respective
Certificate Principal Amounts; provided, however, that the amount of losses
calculated above that would otherwise reduce the Class Principal Amount of the
Class 2-A1 Certificates will first reduce the Class Principal Amount of the
Class 2-A2 Certificates until

                                      S-79



the Class Principal Amount of the Class 2-A2 Certificates has been reduced to
zero, before reducing the Class Principal Amount of the Class 2-A1 Certificates.

      If on any Distribution Date after giving effect to all Realized Losses
incurred with respect to the Pool 1 Mortgage Loans during the related Due Period
and distributions of principal on such Distribution Date, the aggregate Class
Principal Amount of the Group 1 Certificates exceeds the aggregate Stated
Principal Balance of the Pool 1 Mortgage Loans for such Distribution Date (such
excess, a "Group 1 Subordinate Certificate Writedown Amount") the Certificate
Principal Amounts of the Group 1 Subordinate Certificates will be reduced in
inverse order of priority of distribution (that is, such Group 1 Subordinate
Certificate Writedown Amount will be allocated to the Class 1-B6 Certificates
while those Certificates are outstanding, then to the Class 1-B5 Certificates,
and so forth), in reduction of their respective Class Principal Amounts, until
they have been reduced to zero.

      If on any Distribution Date after giving effect to all Realized Losses
incurred with respect to the Pool 2 Mortgage Loans during the related Due Period
and distributions of principal on such Distribution Date, the aggregate Class
Principal Amount of the Group 2 Certificates exceeds the aggregate Stated
Principal Balance of the Pool 2 Mortgage Loans for such Distribution Date (such
excess, a "Group 2 Subordinate Certificate Writedown Amount") the Certificate
Principal Amounts of the Group 2 Subordinate Certificates will be reduced in
inverse order of priority of distribution (that is, such Group 2 Subordinate
Certificate Writedown Amount will be allocated to the Class 2-B6 Certificates
while those Certificates are outstanding, then to the Class 2-B5 Certificates,
and so forth), in reduction of their respective Class Principal Amounts, until
they have been reduced to zero.

      -     In general, a "REALIZED LOSS" means (a) with respect to a Liquidated
            Mortgage Loan, the amount by which the remaining unpaid principal
            balance of that Mortgage Loan plus all accrued and unpaid interest
            thereon and any related expenses exceeds the amount of Liquidation
            Proceeds applied to the principal balance of that Mortgage Loan, or
            (b) the amount by which, in the event of bankruptcy of a borrower, a
            bankruptcy court reduces the secured debt to the value of the
            related Mortgaged Property (a "Deficient Valuation"). In determining
            whether a Realized Loss is a loss of principal or of interest,
            Liquidation Proceeds and other recoveries on a Mortgage Loan will be
            applied first to outstanding expenses incurred with respect to such
            Mortgage Loan, then to accrued, unpaid interest, and finally to
            principal.

      -     A "LIQUIDATED MORTGAGE LOAN" generally is a defaulted Mortgage Loan
            as to which the Mortgage Loan or related REO Property has been
            disposed of and all amounts expected to be recovered in respect of
            that Mortgage Loan have been received by the related Servicer.

      In the event that any amount is recovered in respect of principal of a
Liquidated Mortgage Loan in any Mortgage Pool (after reimbursement of any
unreimbursed advances or expenses of the Servicer), after any related Realized
Loss has been allocated in reduction of the Class Principal Amount of a class of
Certificates related to such Mortgage Pool, as described herein, such amount (a
"Subsequent Recovery") will be distributed to the Certificates of the related
Certificate Group that are still outstanding, in accordance with the priorities
described under "-- Priority of Distributions," and the Class Principal Amount
of each class of related

                                      S-80



Certificates then outstanding that has been reduced due to application of a
Realized Loss will be increased, in order of seniority, by the amount of such
Subsequent Recovery. Any Subsequent Recovery that is received during a
Prepayment Period will be included as part of the Available Distribution Amount
for the related Mortgage Pool and such Distribution Date. It is generally not
anticipated that any such amounts will be recovered, or that any distributions
in respect of Subsequent Recoveries will be made to the Group 1 Subordinate
Certificates prior to the Distribution Date in October 2015 or to the Group 2
Subordinate Certificates prior to the Distribution Date in October 2012.

REPORTS TO CERTIFICATEHOLDERS

      On each Distribution Date, the Securities Administrator will make
available to each Certificateholder and will forward to the rating agencies a

forth, among other things:

      -     the amount of the distributions, separately identified, with respect
            to each class of Certificates;

      -     the amount of the distributions set forth in the first clause above
            allocable to principal, separately identifying the aggregate amount

            principal included in that amount;

      -     the amount of the distributions set forth in the first clause above

            of Monthly Advances for the related Due Period;

      -     in the aggregate and with respect to each Mortgage Pool, the number
            and aggregate principal balance of the Mortgage Loans that were (A)
            delinquent (exclusive of Mortgage Loans in foreclosure) (1) 30 to 59
            days, (2) 60 to 89 days and (3) 90 or more days, (B) in foreclosure
            and delinquent (1) 30 to 59 days, (2) 60 to 89 days and (3) 90 or
            more days and (C) in bankruptcy as of the close of business on the
            last day of the calendar month preceding that Distribution Date;

      -     in the aggregate and with respect to each Mortgage Pool, for any
            Mortgage Loan as to which the related Mortgaged Property was an REO
            property during the preceding calendar month, the loan number, the
            principal balance of that Mortgage Loan as of the close of business
            on the last day of the related Due Period and the date of

      -     in the aggregate and with respect to each Mortgage Pool, the total
            number and principal balance of any REO properties as of the close

            Date; and

      -     the Certificate Interest Rate for each class of Certificates for
            that Distribution Date.

      The Securities Administrator may make available each month, to any
interested party, the monthly statement to Certificateholders via the Securities
Administrator's website. The Securities Administrator's website will be located
at www.ctslink.com, and assistance in using the website can be obtained by
calling the Securities Administrator's customer service desk at (301) 815-6600.
Parties that are unable to use the above distribution option are entitled to
have a paper copy mailed to them via first class mail by notifying the
Securities Administrator at the following address: Wells Fargo Bank, N.A., P.O.
Box 98, Columbia, Maryland 21046 (or for overnight deliveries at 9062 Old
Annapolis Road, Columbia, Maryland 21045). The Securities Administrator will
have the right to change the way such reports are distributed in order to make
such distributions more convenient and/or more accessible, and the Securities
Administrator will provide timely and adequate notification to such parties
regarding any such changes.

      In addition, within a reasonable period of time after the end of each
calendar year, the Securities Administrator will, upon request, prepare and
deliver to each holder of a Certificate of record during the previous calendar
year a statement containing information necessary to enable

                                      S-82



holders of the Certificates to prepare their tax returns. These statements will
not have been examined and reported upon by an independent public accountant.

FINAL SCHEDULED DISTRIBUTION DATE

      The "Final Scheduled Distribution Date" for the Group 1 Certificates is
the Distribution Date in October 2035, which is the Distribution Date in the
month following the scheduled maturity date for the latest maturing Pool 1
Mortgage Loan. The "Final Scheduled Distribution Date" for the Group 2
Certificates is the Distribution Date in April 2035, which is the Distribution
Date in the month following the scheduled maturity date for the latest maturing
Pool 2 Mortgage Loan. The actual final Distribution Date of any class of
Certificates may be earlier or later, and could be substantially earlier, than
such class's Final Scheduled Distribution Date.

OPTIONAL CLEAN-UP REDEMPTION OF THE CERTIFICATES

      On any Distribution Date on or after the Distribution Date (the "Pool 1
Clean-Up Call Date") on which the aggregate outstanding principal balance of the
Pool 1 Mortgage Loans as of the related Due Date is equal to or less than 10% of
the aggregate principal balance of the Pool 1 Mortgage Loans as of the Cut-off
Date, subject to satisfaction of the conditions described in the Pooling and
Servicing Agreement, the Master Servicer may purchase the Pool 1 Mortgage Loans
from the Trust Fund and apply the proceeds to redeem the Group 1 Certificates at
a price equal to 100% of the then aggregate outstanding Class Principal Amount
of such Certificates, plus accrued interest thereon through the end of the
Accrual Period immediately preceding the related Distribution Date (excluding
the amount of any unpaid Net WAC Shortfalls). NO REDEMPTION PREMIUM WILL BE
DISTRIBUTABLE IN CONNECTION WITH SUCH REDEMPTION.

      If the Master Servicer does not exercise its optional clean-up redemption
right on the initial Pool 1 Clean-Up Call Date and redeem the Certificates, then
on the immediately succeeding Distribution Date, the applicable margin specified
in clause (i) of the definition of Certificate Interest Rate for the Class 1-A1,
Class 1-A2, Class 1-B1 and Class 1-B2 Certificates will increase as described at
"Description of the Certificates -- Distributions of Interest" and the increased
margin will remain in effect on all subsequent Distribution Dates.

      On any Distribution Date on or after the Distribution Date on which the
aggregate outstanding principal balance of the Pool 2 Mortgage Loans as of the
related Due Date is less than 1% of the aggregate principal balance of the Pool
2 Mortgage Loans as of the Cut-off Date, subject to satisfaction of the
conditions described in the Pooling and Servicing Agreement, the Master Servicer
may purchase the Pool 2 Mortgage Loans from the Trust Fund and apply the
proceeds to redeem the Group 2 Certificates at a price equal to 100% of the then
aggregate outstanding Class Principal Amount of such Certificates, plus accrued
interest thereon through the end of the Accrual Period immediately preceding the
related Distribution Date (excluding the amount of any unpaid Net WAC
Shortfalls). NO REDEMPTION PREMIUM WILL BE DISTRIBUTABLE IN CONNECTION WITH SUCH
REDEMPTION, AND NO INCREASE IN THE CERTIFICATE INTEREST RATE OF THE GROUP 2
CERTIFICATES WILL OCCUR DUE TO ANY EXERCISE, OR FAILURE BY THE MASTER SERVICER
TO EXERCISE, ANY OPTIONAL PURCHASE RIGHT IN CONNECTION WITH THE POOL 1 MORTGAGE
LOANS OR THE POOL 2 MORTGAGE LOANS.

                                      S-83



      Upon the later of the exercise by the Master Servicer of the purchase
option with respect to Pool 1 Mortgage Loans and the Pool 2 Mortgage Loans, the
Trust Fund will be terminated.

      HSBC Bank USA, National Association, a national banking association
organized and existing under the laws of the United States of America, will be

VOTING RIGHTS

      The Class 1-AR, Class 1-XA, Class 1-XB and Class 2-AR Certificates each
will be allocated 1% of all voting rights, and the other classes of Certificates
will be allocated 96% of all voting rights under the Pooling and Servicing
Agreement. Voting rights will be allocated among the classes of Certificates in
proportion to their respective Class Principal Amounts or Class Notional
Amounts, as applicable, and among Certificates of such class in proportion to
their Percentage Interests. The "Percentage Interest" of a Certificate will be a
fraction, expressed as a percentage, the numerator of which is that
Certificate's Certificate Principal Amount or notional amount, and the
denominator of which is the applicable Class Principal Amount or Class Notional
Amount.

WELLS FARGO

      Wells Fargo Bank, N.A. ("Wells Fargo") is an indirect, wholly owned
subsidiary of Wells Fargo & Company. Wells Fargo is engaged in the business of
(i) originating, purchasing and selling residential mortgage loans in its own
name and through its affiliates and (ii) servicing residential mortgage loans
for its own account and for the account of others. Wells Fargo is an approved
servicer of Fannie Mae and Freddie Mac. Wells Fargo's principal office for
servicing functions is located at 1 Home Campus, Des Moines, Iowa 50328-0001.

      The following table sets forth certain information, as reported by Wells

                         SERVICING OF THE MORTGAGE LOANS

GENERAL

      Wells Fargo Bank, N.A., with its principal master servicing offices at
9062 Old Annapolis Road, Columbia, Maryland 21045, will perform the duties of
Master Servicer with respect to the Mortgage Loans, in accordance with the terms
set forth in the Pooling and Servicing Agreement. The Master Servicer will not
be ultimately responsible for the performance of the servicing activities by a
Servicer, except as described under "-- Servicing Compensation and Payment of
Expenses; Master Servicing Compensation," "-- Adjustment to Servicing Fees in
Connection with Certain Prepaid Mortgage Loans" and "-- Advances" below. If any
Servicer fails to fulfill its obligations under the applicable Servicing
Agreement, the Master Servicer is obligated to terminate that Servicer and
appoint a successor servicer as provided in the Pooling and Servicing Agreement.

SERVICING AND COLLECTION PROCEDURES

      Servicing functions to be performed by each Servicer under the related
Servicing Agreement include collection and remittance of principal and interest
payments, administration of mortgage escrow accounts, collection of certain
insurance claims and, if necessary, foreclosure. Each Servicer may contract with
subservicers to perform some or all of such Servicer's servicing duties, but the
Servicer will not thereby be released from its obligations under the related
Servicing Agreement. When used herein with respect to servicing obligations, the
term Servicer includes a subservicer.

      Each Servicer will make reasonable efforts to collect all payments called
for under the Mortgage Loans and will, consistent with the related Servicing
Agreement and any primary mortgage insurance policy, follow such collection
procedures as are customary with respect to mortgage loans that are comparable
to the Mortgage Loans. Consistent with the above, each Servicer may, in its
discretion, (i) waive any assumption fee, late payment or other charge in
connection with a Mortgage Loan and (ii) to the extent not consistent with the
coverage of such Mortgage Loan by a primary mortgage insurance policy, arrange
with a mortgagor a schedule for the liquidation of delinquencies. The
Depositor's prior approval or consent will be required for certain servicing
activities such as modification of the terms of any Mortgage Loan and the sale
of any defaulted Mortgage Loan or REO Property.

      Pursuant to each Servicing Agreement, the Servicer will deposit
collections on the Mortgage Loans into the Custodial Account established by it.
Each Custodial Account is required to be kept segregated from operating accounts
of the related Servicer and to meet the eligibility criteria set forth in the
related Servicing Agreement. Under each Servicing Agreement, amounts on deposit
in the Custodial Account may be invested in certain permitted investments
described therein. Any losses resulting from such investments are required to be
reimbursed to the Custodial Account by the related Servicer out of its own
funds.

      On or before the Closing Date, the Securities Administrator, on behalf of
the Trustee, will establish the Distribution Account into which each Servicer
will remit all amounts required to be

                                     S-88


deposited therein (net of such Servicer's servicing compensation) on the
remittance date specified in the related Servicing Agreement. Generally, each
Servicer will determine the amount of Monthly Advances for the related Due
Period on or before the 18th day of each month, or, if the 18th is not a
Business Day, on the immediately preceding Business Day, (each, a "Determination
Date"), and will furnish to the Master Servicer information with respect to loan
level remittance data for such month's remittance on the reporting date
specified in the related Servicing Agreement.

      Events of default under the Servicing Agreements include (i) any failure
of the Servicer to remit to the Distribution Account any required payment which
continues unremedied for a specified period after the giving of written notice
of such failure to the Servicer; (ii) any failure by the Servicer to make a
Monthly Advance as required under the Servicing Agreement, unless cured as
specified therein; (iii) any failure by the Servicer duly to observe or perform
in any material respect any of its other covenants or agreements in the
Servicing Agreement which continues unremedied for a specified period after the
giving of written notice of such failure to the Servicer; and (iv) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding and certain actions by or on behalf of the
Servicer indicating its insolvency, reorganization or inability to pay its
obligations.

      In the event of a default by a Servicer under its Servicing Agreement, the
Master Servicer will have the right to remove the Servicer and will exercise
that right if it considers such removal to be in the best interest of the
Certificateholders. In the event that the Master Servicer removes a Servicer,
the Master Servicer will, in accordance with the Pooling and Servicing
Agreement, act as successor servicer under the related Servicing Agreement or
will appoint a successor servicer reasonably acceptable to the Depositor and the
Trustee. In connection with the removal of a Servicer, the Master Servicer will
be entitled to be reimbursed from the assets of the Trust Fund for all of its
reasonable costs associated with the termination of the Servicer and the
transfer of servicing to a successor servicer.

SERVICING COMPENSATION AND PAYMENT OF EXPENSES; MASTER SERVICING COMPENSATION

      Each Servicer will be entitled to receive, from interest actually
collected on each Mortgage Loan serviced by it, a servicing fee (the "Servicing
Fee") equal to the product of (1) the principal balance of such Mortgage Loans
as of the first day of the related Due Period and (2) a per annum rate (the
"Servicing Fee Rate") ranging from approximately 0.250% to approximately 1.125%,
in the case of Pool 1, and a rate of approximately 0.250%, in the case of
Pool 2. As of the Cut-off Date, the weighted average Servicing Fee Rate for the
Pool 1 Mortgage Loans is approximately 0.361% per annum. As of the Cut-off Date,
the weighted average Servicing Fee Rate for the Pool 2 Mortgage Loans is
approximately 0.250% per annum. The Servicers are also entitled to receive, as
additional servicing compensation, all late payment fees, assumption fees and
other similar charges and all reinvestment income earned on amounts on deposit
in the Custodial Accounts, and additionally, Wells Fargo is entitled to receive
as additional servicing compensation, as to Pool 2 Mortgage Loans, any
Incremental Interest.

      The Master Servicer will be paid a monthly fee (the "Master Servicing
Fee") with respect to each Mortgage Loan in the Trust Fund, calculated as
0.0175% per annum (the "Master Servicing Fee Rate") of the Stated Principal
Balance of each Mortgage Loan as of the first day of

                                     S-89


the related Due Period. The Master Servicer also is entitled to receive as
additional master servicing compensation the investment earnings on amounts on
deposit in the Distribution Account. The Master Servicer will pay the fees of
the Trustee from the Master Servicing Fee.

      The amount of the Master Servicing Fee and each Servicer's Servicing Fee
is subject to adjustment with respect to prepaid Mortgage Loans, as described
below under "-- Adjustment to Servicing Fees in Connection with Certain Prepaid
Mortgage Loans."

ADJUSTMENT TO SERVICING FEES IN CONNECTION WITH CERTAIN PREPAID MORTGAGE LOANS

      When a borrower prepays a Mortgage Loan in full between Due Dates, the
borrower is required to pay interest on the amount prepaid only to the date of
prepayment and not thereafter. Principal prepayments by borrowers received by a
Servicer during the related Prepayment Period for a Distribution Date will be
distributed to Certificateholders on the related Distribution Date. Thus, less
than one month's interest may have been collected on Mortgage Loans that have
been prepaid in full with respect to any Distribution Date. Pursuant to each
Servicing Agreement, either (i) the related Servicing Fee for any month will be
reduced (but not below zero) by the amount of any Prepayment Interest Shortfall
or (ii) the related Servicer will be required to make payments in respect of
Prepayment Interest Shortfalls from its own funds with respect to Mortgage Loans
serviced by such Servicer. The Master Servicer is obligated to reduce a portion
of its Master Servicing Fee for the related Distribution Date to the extent
necessary to fund any Prepayment Interest Shortfalls required to be paid but not
paid by a Servicer. The amount of interest available to be paid to
Certificateholders will be reduced by any uncompensated Prepayment Interest
Shortfalls.

ADVANCES

      Subject to the limitations described in the following paragraph, each
Servicer will be required to advance prior to each Distribution Date, from its
own funds, or funds in its Custodial Account that are not otherwise required to
be remitted to the Distribution Account for such Distribution Date, an amount
equal to the scheduled payment of interest at the related Mortgage Rate (less
the applicable Servicing Fee Rate) and scheduled principal payment on each
Mortgage Loan which were due on the related Due Date and which were not received
prior to the related Determination Date (any such advance, a "Monthly Advance").
The Master Servicer will be obligated to make any required Monthly Advance if
the Servicer fails in its obligation to do so, to the extent provided in the
Pooling and the Servicing Agreement and the related Servicing Agreement.

      Monthly Advances are intended to maintain a regular flow of scheduled
interest and principal payments on the Certificates rather than to guarantee or
insure against losses. Each Servicer is obligated to make Monthly Advances with
respect to delinquent payments of interest and principal on each Mortgage Loan
serviced by it, to the extent that such Monthly Advances are, in its reasonable
judgment, recoverable from future payments and collections or insurance payments
or proceeds of liquidation of the related Mortgage Loans. Any failure by a
Servicer to make a Monthly Advance as required under the related Servicing
Agreement will constitute a default thereunder, in which case the Master
Servicer will be required, as successor servicer, to make a Monthly Advance in
accordance with the terms of the Pooling and Servicing Agreement;

                                     S-90


provided, however, that in no event will the Master Servicer be required to make
a Monthly Advance that is not, in its reasonable judgment, recoverable from
future payments and collections or insurance payments or proceeds of liquidation
of the related Mortgage Loans. If a Servicer determines on any Determination
Date to make a Monthly Advance, such Monthly Advance will be included with the
payment to Certificateholders on the related Distribution Date. Any failure by
the Master Servicer to make a Monthly Advance as required under the Pooling and
Servicing Agreement will constitute a Master Servicer Default thereunder, in
which case the Trustee or the successor master servicer will be obligated to
make such Monthly Advance.

EVIDENCE AS TO COMPLIANCE

      Each Servicing Agreement provides that on or before a specified date in
each year, a firm of independent public accountants will furnish a statement to
the Master Servicer, the Depositor and the Trustee to the effect that, on the
basis of the examination by such firm conducted substantially in compliance with
the Uniform Single Attestation Program for Mortgage Bankers, the servicing by or
on behalf of the Servicer was conducted in compliance with its Servicing
Agreement, except for any significant exceptions or errors in records that, in
the opinion of the firm, the Uniform Single Attestation Program for Mortgage
Bankers requires it to report.

      Each Servicing Agreement also provides for delivery to the Master
Servicer, the Depositor and the Trustee, on or before a specified date in each,
of an annual officer's certificate to the effect that the Servicer has fulfilled
its obligations under its Servicing Agreement throughout the preceding year.

MASTER SERVICER DEFAULT; SERVICER DEFAULT

      Events of default by the Master Servicer under the Pooling and Servicing
Agreement include (i) any failure by the Master Servicer to make a back-up
Monthly Advance as required under the Pooling and Servicing Agreement, unless
cured as specified therein; (ii) any failure by the Master Servicer duly to
observe or perform in any material respect any of its other covenants or
agreements in the Pooling and Servicing Agreement which continues unremedied for
a specified period after the giving of written notice of such failure to the
Master Servicer; and (iii) certain events of insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceeding and certain actions
by on or behalf of the Master Servicer indicating its insolvency, reorganization
or inability to pay its obligations.

      If the Master Servicer is in default in its obligations under the Pooling
and Servicing Agreement, the Trustee may, and must if directed to do so by
Certificateholders having more than 50% of the Class Principal Amount applicable
to each class of Certificates affected thereby, terminate the Master Servicer
and either appoint a successor Master Servicer in accordance with the Pooling
and Servicing Agreement or succeed to the responsibilities of the Master
Servicer.

      If a Servicer is in default in its obligations under the applicable
Servicing Agreement, the Master Servicer may, at its option, terminate the
defaulting Servicer and either appoint a successor Servicer in accordance with
the applicable Servicing Agreement and the Pooling and Servicing Agreement or
succeed to the responsibilities of the terminated Servicer.

                                     S-91


RESIGNATION OF SERVICERS; ASSIGNMENT AND MERGER

      A Servicer may not resign from its obligations and duties under its
Servicing Agreement or assign or transfer its rights, duties or obligations
except (i) upon a determination that its duties thereunder are no longer
permissible under applicable law, (ii) in certain cases, upon the sale of
substantially all of its assets or (iii) upon a sale of its servicing rights
with respect to the Mortgage Loans with the prior written consent of the
Depositor, which consent may not be unreasonably withheld. No such resignation
will become effective until the Master Servicer or a successor servicer approved
by it has assumed the Servicer's obligations and duties under such Servicing
Agreement.

      Any person into which a Servicer may be merged or consolidated, any person
resulting from any merger or consolidation which a Servicer is a party, any
person succeeding to the business of a Servicer or any person to whom a Servicer
assigns or transfers its duties and obligations, will be the successor of such
Servicer under the related Servicing Agreement.

                   YIELD, PREPAYMENT AND WEIGHTED AVERAGE LIFE

YIELD CONSIDERATIONS

      The yields to maturity (or to early termination) of the Offered
Certificates will be affected by the rate of principal payments (including
prepayments, which may include amounts received by virtue of purchase,
condemnation, insurance or foreclosure) on the Mortgage Loans in the related
Mortgage Pool. Yields will also be affected by the extent to which related
Mortgage Loans bearing higher Mortgage Rates prepay at a more rapid rate than
Mortgage Loans with lower Mortgage Rates, the amount and timing of borrower
delinquencies and defaults resulting in Realized Losses, the purchase price for
the Offered Certificates and other factors.

      Yields on the Group 1 Certificates will be affected by the rate of
principal payments on the Pool 1 Mortgage Loans, and yields on the Group 2
Certificates will be affected by the rate of principal prepayments on the Pool 2
Mortgage Loans. However, because there exists no cross-collateralization among
the Mortgage Pools, principal payments experienced by one Mortgage Pool will
have no affect on the yield of the Certificates unrelated to that Mortgage Pool.

      Principal prepayments may be influenced by a variety of economic,
geographic, demographic, social, tax, legal and other factors. As of the Cut-off
Date, approximately 95.04% of the Pool 1 Mortgage Loans and all of the Pool 2
Mortgage Loans may be voluntarily prepaid in full or in part without the payment
of any penalty or premium. In general, if prevailing interest rates fall below
the interest rates on the Mortgage Loans, the Mortgage Loans are likely to be
subject to higher prepayments than if prevailing rates remain at or above the
interest rates on the Mortgage Loans. Conversely, if prevailing interest rates
rise above the interest rates on the Mortgage Loans, the rate of prepayment
would be expected to decrease. Other factors affecting prepayment of the
Mortgage Loans include such factors as changes in borrowers' housing needs, job
transfers, unemployment, borrowers' net equity in the mortgaged properties,
changes in the value of the mortgaged properties, mortgage market interest rates
and servicing decisions. The Mortgage Loans generally have due-on-sale clauses.

                                     S-92


      All of the Pool 2 Mortgage Loans are Relationship ARMs. A Relationship ARM
is subject to a Mortgage Rate increase during the initial fixed-rate period in
the event the mortgagor fails to maintain a required banking relationship with
Wells Fargo. In the event of such an increase, the Mortgage Loan will be
re-amortized over its remaining term, and the monthly payments to be made by the
mortgagor will increase. In the event Wells Fargo exercises its right to
increase the Mortgage Rate by the Incremental Rate, a mortgagor may be more
likely to prepay the Mortgage Loan through refinancing or otherwise. See "The
Mortgage Pools" in this prospectus supplement. An increase in the Mortgage Rate
on a Relationship ARM will not be accompanied by an increase in the Periodic Cap
or Maximum Mortgage Rate on such Mortgage Loan. Therefore, the Mortgage Rate
adjustments on Relationship ARMs may be more likely to be subject to limitation
by operation of such Periodic Caps and Maximum Mortgage Rates than a comparable
loan which was originated with an initial Mortgage Rate of the Relationship ARM
plus the Incremental Rate.

      In addition, if a Pool 2 Mortgage Loan satisfies the eligibility criteria
of Wells Fargo Bank's retention program, the related borrower may be offered the
opportunity to refinance such Mortgage Loan at the current market interest rate
without the application of significant borrower credit or property underwriting
standards. Therefore, the Pool 2 Mortgage Loans may be more likely to experience
prepayments due to refinancing than would occur if such retention program were
not in place.

      As described in this prospectus supplement, the Certificate Interest Rate
of each Class of the Group 2 Certificates will be based on the Net WAC for Pool
2. If prepayments on Pool 2 Mortgage Loans bearing higher Mortgage Rates occur
at a more rapid rate than prepayments on Pool 2 Mortgage Loans bearing lower
Mortgage Rates, the Net WAC for Pool 2 will be reduced, and accordingly, the
Certificate Interest Rate of the Group 2 Certificates will also be reduced.

      As of the Cut-off Date, approximately 59.54%, 39.30% and 1.16% of the Pool
1 Mortgage Loans are One-Month LIBOR loans, Six-Month LIBOR loans and Prime Rate
loans, respectively, and all of the Pool 2 Mortgage Loans are One-Year CMT
Loans. Increases and decreases in the Mortgage Rate on a Mortgage Loan will be
limited (except in the case of the first rate adjustment) by the Maximum
Mortgage Rate, the minimum Mortgage Rate and the Periodic Cap, if any, and will
be based on the applicable index in effect on the applicable date prior to the
related interest rate adjustment date plus the applicable gross margin. The
applicable index may not rise and fall consistently with Mortgage Rates. In
addition, with respect to Pool 2, the Mortgage Rate for each Pool 2 Mortgage
Loan is fixed during an initial period of approximately five years from the date
of origination. As a result, the Mortgage Rates on the Mortgage Loans at any
time may not equal the prevailing mortgage rates for similar adjustable rate
loans, and accordingly the prepayment rate may be lower or higher than would
otherwise be anticipated. Moreover, some borrowers who prefer the certainty
provided by fixed rate mortgage loans may, nevertheless, obtain adjustable rate
mortgage loans (especially if they are able to obtain a Relationship ARM, which
has a below-market Mortgage Rate during the fixed-rate period) at a time when
they regard the mortgage rates (and, therefore, the payments) on fixed rate
mortgage loans as unacceptably high. These borrowers may be induced to refinance
adjustable rate loans when the mortgage rates and monthly payments on comparable
fixed rate mortgage loans decline to levels which these borrowers regard as
acceptable, even though such mortgage rates and monthly payments may be
significantly higher than the current mortgage rates and

                                     S-93


monthly payments on the borrowers' adjustable rate mortgage loans. The ability
to refinance a Mortgage Loan will depend on a number of factors prevailing at
the time refinancing is desired, including, without limitation, real estate
values, the borrower's financial situation, prevailing mortgage rates, the
borrower's equity in the related mortgaged property, tax laws and prevailing
general economic conditions. The eligibility of the Pool 2 Mortgage Loans for
the Wells Fargo retention program may increase the rate of prepayments on such
loans. In addition, the Certificate Interest Rates on the Group 2 Certificates,
beginning with the related Accrual Period following the first adjustment date
may decrease, and may decrease significantly, after the Mortgage Rates on the
Pool 2 Mortgage Loans begin to adjust.

      The rate of principal payments on the Mortgage Loans will also be affected
by the amortization schedules of the Mortgage Loans, the rate and timing of
prepayments thereon, liquidations of defaulted Mortgage Loans and purchases of
Mortgage Loans due to certain breaches of representations and warranties or
defective documentation. The timing of changes in the rate of prepayments,
liquidations and purchases of the related Mortgage Loans may, and the timing of
Realized Losses will, significantly affect the yield to an investor, even if the
average rate of principal payments experienced over time is consistent with an
investor's expectation. Because the rate and timing of principal payments on the
Mortgage Loans will depend on future events and on a variety of factors, no
assurance can be given as to such rate or the timing of principal payments on
the Offered Certificates. In general, the earlier a prepayment of principal of
the related Mortgage Loans, the greater the effect on an investor's yield. 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 Certificates may not be offset by a
subsequent like decrease (or increase) in the rate of principal payments.

      From time to time, areas of the United States may be affected by flooding,
severe storms, tornadoes, hurricanes, landslides, wildfires, earthquakes or
other natural disasters. Recently Hurricane Katrina caused extensive damages to
parts of Alabama, Louisiana, Mississippi and Florida, and Hurricane Rita caused
extensive damage in affected areas, including parts of Louisiana and Texas.
There are no Mortgage Loans with Mortgage Properties located in the areas of
Alabama, Louisiana, Mississippi or Texas which the Federal Emergency Management
Agency has declared to be an Individual Assistance designated area. However,
approximately 20.73% of the Mortgage Loans in Pool 1 are secured by Mortgaged
Properties located in other areas of Alabama, Louisiana, Mississippi, Texas and
Florida. These properties may have been damaged by Hurricane Katrina or
Hurricane Rita, although the damage from these hurricanes in these areas may be
less severe, or they may be near or otherwise affected by weakened economic
conditions in and around the areas damaged by the storm.

      Under the Mortgage Loan Purchase Agreement, the Seller will represent and
warrant that as of the Closing Date each Mortgaged Property was free of material
damage. In the event of an uncured breach of this representation and warranty
that materially and adversely affects the interests of Certificateholders, the
Seller will be required to repurchase the affected Mortgage Loan or substitute
another mortgage loan therefor. If any damage caused by flooding, storms,
wildfires, landslides or earthquakes (or other cause) occurs after the Closing
Date, the Seller will not have any repurchase obligation. In addition, the
standard hazard policies covering the Mortgaged Properties generally do not
cover damage caused by earthquakes, flooding and

                                     S-94


landslides, and earthquake, flood or landslide insurance may not have been
obtained with respect to such Mortgaged Properties. As a consequence, Realized
Losses could result. To the extent that the insurance proceeds received with
respect to any damaged Mortgaged Properties are not applied to the restoration
thereof, the proceeds will be used to prepay the related Mortgage Loans in whole
or in part. Any purchases or repayments of the Mortgage Loans may reduce the
weighted average lives of the Offered Certificates and will reduce the yields on
the Offered Certificates to the extent they are purchased at a premium.

      Prepayments, liquidations and purchases of the Mortgage Loans will result
in distributions to Certificateholders of principal amounts that would otherwise
be distributed over the remaining terms of such Mortgage Loans. The rate of
defaults on the Mortgage Loans will also affect the rate and timing of principal
payments on the Mortgage Loans. In general, defaults on Mortgage Loans are
expected to occur with greater frequency in their early years.

      As described herein, approximately 0.04% and 99.96% of the Pool 1 Mortgage
Loans provide for only monthly interest payments for the first five or ten
years, respectively, following origination, and approximately 60.75% of the Pool
2 Mortgage Loans provide for only monthly interest payments for the first five
years following origination. Other considerations aside, due to such
characteristics, borrowers may be disinclined to prepay the Mortgage Loans
during such interest-only period. In addition, because no principal is due on
the Mortgage Loans during the initial five- or ten-year period, the Certificates
will amortize at a slower rate during such period than would otherwise be the
case. Thereafter, when the monthly payments on the Mortgage Loans are
recalculated on the basis of a level payment amortization schedule for the
remaining term of such Mortgage Loan, as described herein, principal payments on
the Certificates are expected to increase correspondingly, and, in any case, at
a faster rate than if payments on the Mortgage Loans were calculated on the
basis of a 25 to 30 year amortization schedule. Notwithstanding the foregoing,
no assurance can be given as to any prepayment rate on the Mortgage Loans.

      As described under "Description of the Certificates -- Distributions of
Principal" herein, scheduled and unscheduled principal payments on the Mortgage
Loans in a Mortgage Pool will generally be allocated disproportionately to the
Senior Certificates of the related Certificate Group during the first ten years
following the Closing Date (except as described herein) or if certain conditions
are met. Such allocation will initially accelerate the amortization of the
Senior Certificates.

      The yields on the Offered Certificates may also be adversely affected by
Net Prepayment Interest Shortfalls. The Certificate Interest Rates and the
yields on the Group 1 Certificates will be affected by the level of One-Month
LIBOR, Six Month LIBOR and the Prime Rate from time to time; and the yields on
the Group 2 Certificates will be affected by the level of One-Year CMT from time
to time. Moreover, the yield on each class of Offered Certificates will be
affected by the Mortgage Rates of the Mortgage Loans in the related Mortgage
Pool from time to time, as described under "Risk Factors -- Your Yield May Be
Affected by Changes in Interest Rates." No prediction can be made as to future
levels of One-Month LIBOR, Six-Month LIBOR, Prime Rate or One-Year CMT or as to
the timing of any changes therein.

                                     S-95


      The yields to investors in the Group 1 Certificates may be significantly
affected, and the yields to investors in the Group 2 Certificates may be
affected, by the exercise of the Master Servicer's option to redeem such
Certificates, as described herein. See "Description of the Certificates --
Optional Clean-Up Redemption of the Certificates." If the purchaser of a
Certificate offered at a discount from its initial principal amount calculates
its anticipated yield to maturity (or early termination) based on an assumed
rate of payment of principal that is faster than that actually experienced on
the related Mortgage Loans, the actual yield may be lower than that so
calculated. There will be no increase in the Certificate Interest Rate of the
Group 2 Certificates due to any exercise, or failure by the Master Servicer to
exercise, any optional purchase right in connection with the Pool 1 Mortgage
Loans or the Pool 2 Mortgage Loans.

      If the purchaser of a Class 1-XA or Class 1-XB Certificate or another
Certificate offered at a premium, calculates its anticipated yield based on an
assumed rate of payment of principal that is slower than that actually
experienced on the related Mortgage Loans, the actual yield may be lower than
that so calculated. The effective yield to holders of the Offered Certificates
(other than the LIBOR Certificates) will be lower than the yield otherwise
produced by the applicable Certificate Interest Rate and the related purchase
price because monthly distributions will not be payable to such holders until
the 20th day of the month (or the immediately following Business Day if such day
is not a Business Day) following the month in which interest accrues on the
Mortgage Loans (without any additional distribution of interest or earnings
thereon in respect of such delay).

      Prospective purchasers of the Class 1-XA and Class 1-XB Certificates
should carefully consider the risk that a rapid rate of principal prepayments on
the Mortgage Loans in Pool 1 could result in the failure of such purchasers to
recover their initial investments.

SUBORDINATION OF THE OFFERED SUBORDINATE CERTIFICATES

      On each Distribution Date, the holders of classes of Certificates having a
relatively higher priority of distribution will have a preferential right to
receive amounts of interest and principal due them on such Distribution Date
before any distributions are made on any class of Certificates subordinate to
such higher ranking class. As a result, the yields to maturity and the aggregate
amount of distributions on the Subordinate Certificates will be more sensitive
than the yields of higher ranking Certificates to the rate of delinquencies and
defaults on the Mortgage Loans.

      As more fully described herein, the principal portion of Realized Losses
on the Mortgage Loans will be allocated first to the lower ranking class of
Subordinate Certificates, then to the higher ranking class of Subordinate
Certificates, in inverse order of priority, until the Class Principal Amount of
each such class has been reduced to zero, before any such Realized Losses will
be allocated to the Senior Certificates. In addition, if the Mortgage Loans in
Pool 1 experience losses after the aggregate Class Principal Amount of the Group
1 Subordinate Certificates has been reduced to zero, then the portion of any
Realized Losses allocable to the Class 1-A1 Certificates will first be allocated
to the Class 1-A2 Certificates until the Class Principal Amount of the Class
1-A2 Certificates has been reduced to zero; and if the Mortgage Loans in Pool 2
experience losses after the aggregate Class Principal Amount of the Group 2
Subordinate Certificates has been reduced to zero, then the portion of any
Realized Losses allocable to the Class 2-A1 Certificates will first be allocated
to the Class 2-A2 Certificates until

                                     S-96


the Class Principal Amount of the Class 2-A2 Certificates has been reduced to
zero. The interest portion of Realized Losses on the Mortgage Loans will reduce
the amount available for distribution on the related Distribution Date to the
lowest ranking related class outstanding on such date.

WEIGHTED AVERAGE LIFE

      Weighted average life refers to the average amount of time that will
elapse from the date of issuance of a security to the date of distribution to
the investor of each dollar distributed in net reduction of principal of such
security (assuming no losses). The weighted average lives of the Offered
Certificates will be influenced by, among other things, the rate at which
principal of the related Mortgage Loans is paid, which may be in the form of
scheduled amortization, prepayments or liquidations.

      For a discussion of the factors which may influence the rate of payments
(including prepayments) of the Mortgage Loans, see "Risk Factors -- Prepayments
are Unpredictable and Affect Yield" in the accompanying prospectus.

      Prepayments of mortgage loans are commonly measured relative to a
prepayment standard or model. The model used in this prospectus supplement for
the Mortgage Loans is a Constant Prepayment Rate ("CPR"). CPR represents an
assumed constant rate of prepayment each month, relative to the then outstanding
principal balance of a pool of mortgage loans, for the life of such mortgage
loans.

      CPR DOES NOT PURPORT TO BE EITHER A HISTORICAL DESCRIPTION OF THE
PREPAYMENT EXPERIENCE OF ANY POOL OF MORTGAGE LOANS OR A PREDICTION OF THE
ANTICIPATED RATE OF PREPAYMENT OF ANY POOL OF MORTGAGE LOANS, INCLUDING THE
MORTGAGE LOANS.

      The following tables were prepared on the basis of the following
assumptions (collectively, the "Structuring Assumptions"): (i) distributions in
respect of the Certificates are received in cash on the 20th day of each month
commencing in October 2005, (ii) the Mortgage Loans prepay at the indicated
percentages of CPR, (iii) no defaults or delinquencies occur in the payment by
borrowers of principal and interest on the Mortgage Loans, and no shortfalls are
incurred due to the application of the Relief Act, (iv) the Seller is not
required to purchase or substitute for any Mortgage Loan, (v) scheduled monthly
payments on the Mortgage Loans are received on the first day of each month
commencing in October 2005 and are computed prior to giving effect to any
prepayments received in the prior month, (vi) prepayments are allocated as
described herein without giving effect to loss and delinquency tests, (vii)
prepayments represent voluntary prepayments in full of individual Mortgage Loans
and are received on the last day of each month, commencing in September 2005 and
include 30 days' interest, (viii) the scheduled monthly payment for each
Mortgage Loan has been calculated based on the assumed mortgage loan
characteristics described in item (xiv) below such that each such Mortgage Loan
will amortize in amounts sufficient to repay the principal balance of such
assumed mortgage loan by its remaining term to maturity (taking into account any
interest-only period), (ix) interest accrues on each class of Certificates at
the applicable Certificate Interest Rate described under "Description of the
Certificates -- Distributions of Interest" in this prospectus supplement, (x)
the initial Class Principal Amount of each class of Certificates is as described
in this

                                     S-97


prospectus supplement, (xi) Six-Month LIBOR is equal to 4.06%, One-Month LIBOR
is equal to 3.82%, the Prime Rate is equal to 6.50% and One-Year CMT is equal to
3.793% at all times; (xii) no exercise of any optional clean-up redemption with
respect to Pool 1 or Pool 2 will occur, except that this assumption does not
apply to the calculation of weighted average lives to the optional clean-up
redemption with respect to Pool 1 or Pool 2, (xiii) the Closing Date of the sale
of the Offered Certificates is September 29, 2005; and (xiv) the Mortgage Loans
in each Mortgage Pool are aggregated into assumed Mortgage Loans having the
following characteristics:

*IO indicates that such assumed mortgage loan is an interest-only loan.

                                      S-100



      The actual characteristics and the performance of the Mortgage Loans will
differ from the assumptions used in constructing the tables set forth below,
which are hypothetical in nature and are provided only to give a general sense
of how the principal cash flows might behave under varying prepayment scenarios.
For example, it is not expected that the Mortgage Loans will prepay at a
constant rate until maturity, that all of the Mortgage Loans will prepay at the
same rate or that there will be no defaults or delinquencies on the Mortgage
Loans. Moreover, the diverse remaining terms to maturity and the Mortgage Rates
of the Mortgage Loans could produce slower or faster principal distributions
than indicated in the tables at the various percentages of CPR specified, even
if the weighted average remaining term to maturity and weighted average Mortgage
Rate of the Mortgage Loans are assumed. Any difference between such assumptions
and the actual characteristics and performance of the Mortgage Loans, or actual
prepayment or loss experience, will cause the percentages of initial Class
Principal Amounts outstanding over time and the weighted average lives of the
Offered Certificates to differ (which difference could be material) from the
corresponding information in the tables for each indicated percentage of CPR.

      Subject to the foregoing discussion and assumptions, the following tables
indicate the weighted average lives of the Offered Certificates (other than the
Class 1-AR and Class 2-AR Certificates and the Class X Certificates) and set
forth the percentages of the initial Class Principal Amounts of such Offered
Certificates that would be outstanding after each of the Distribution Dates
shown at various percentages of CPR.

      The weighted average life of an Offered Certificate is determined by (1)
multiplying the net reduction, if any, of the applicable Class Principal Amount
by the number of years from the date of issuance of the Offered Certificate to
the related Distribution Date, (2) adding the results and (3) dividing the sum
by the aggregate of the net reductions of Class Principal Amount described in
(1) above.

SENSITIVITY OF THE CLASS 1-XA AND CLASS 1-XB CERTIFICATES

      The yield to maturity of the Class 1-XA and Class 1-XB Certificates will
be sensitive to the rate and timing of principal payments (including
prepayments, liquidations, repurchases and defaults) on the related Mortgage
Loans, which may fluctuate significantly from time to time. An investor should
fully consider the associated risks, including the risk that a relatively fast
rate of principal payments (including prepayments, liquidations, repurchases and
defaults) on the related Mortgage Loans will have a material negative effect on
the yield to investors in the Class 1-XA and Class 1-XB Certificates and could
result in the failure of investors in such Certificates to recoup their initial
investment.

      The following tables (the "Yield Tables") were prepared on the basis of
the Structuring Assumptions (except for the pricing assumptions that are listed
below) and demonstrate the sensitivity of the pre-tax yields on the Class 1-XA
and Class 1-XB Certificates to various constant rates of prepayment by
projecting the aggregate payments of interest on such Certificates and the
corresponding pre-tax yields on a corporate bond equivalent ("CBE") basis,
assuming distributions on the related Mortgage Loans are made as set forth in
the Pooling and Servicing Agreement.

- -----------
*   The price shown does not include accrued interest. Accrued interest has
    been added to such price for calculating the yields set forth in the table
    above.

      Based upon the above assumptions, at approximately 52% CPR (at an assumed
purchase price of 1.30% of the related Class Notional Amount, excluding accrued
interest, but adding

                                     S-106



accrued interest to the price for purposes of calculating yield), and 58% CPR
(at an assumed purchase price of 2.00% of the related Class Notional Amount,
excluding accrued interest, but adding accrued interest to the price for
purposes of calculating yield), the pre-tax yield to maturity of the Class 1-XA
and Class 1-XB Certificates will be less than 0%, respectively. If the rate of
prepayments on the related Mortgage Loans were to exceed the applicable levels
for as little as one month, while equaling such level for all other months, the
Class 1-XA and Class 1-XB Certificateholders would not fully recoup their
initial investment.

      The pre-tax yields set forth in the preceding tables were calculated by
determining the monthly discount rates which, when applied to the assumed
streams of cash flows to be paid on the Class 1-XA and Class 1-XB Certificates,
would cause the discounted present value of such assumed stream of cash flows to
the Closing Date to equal the assumed purchase prices (plus accrued interest),
and converting such monthly rates to CBE rates. Such calculation does not take
into account the interest rates at which funds received by Certificateholders as
distributions on the Class 1-XA and Class 1-XB Certificates may be reinvested
and consequently does not purport to reflect the return on any investment in
such Certificates when such reinvestment rates are considered.

      It is highly unlikely that the Mortgage Loans will prepay at the same rate
until maturity or that all of the Mortgage Loans will prepay at the same rate or
time or that prepayments will be spread evenly among Mortgage Loans with
differing gross margins. As a result of these factors, the pre-tax yields on the
Class 1-XA and Class 1-XB Certificates are likely to differ from those shown in
such tables, even if all of the related Mortgage Loans prepay at the indicated
percentages of CPR. No representation is made as to the actual rate of principal
payments on the related Mortgage Loans (or the Mortgage Rates thereon) for any
period or over the lives of the Class 1-XA and Class 1-XB Certificates or as to
the yields on such Certificates. Investors must make their own decisions as to
the appropriate prepayment assumptions to be used in deciding whether to
purchase such Certificates.

                                 USE OF PROCEEDS

      The net proceeds from the sale of the Offered Certificates will be applied
by the Depositor to pay for the acquisition of the Mortgage Loans from the
Seller. See "Use of Proceeds" in the accompanying prospectus and "Method of
Distribution" in this prospectus supplement.

                         FEDERAL INCOME TAX CONSEQUENCES

      For federal income tax purposes the Trust Fund, exclusive of the Reserve
Fund and rights in the Additional Collateral, will comprise multiple REMICs.
Elections will be made to treat each REMIC formed pursuant to the Pooling and
Servicing Agreement as a REMIC for federal income tax purposes. Each of the
Certificates, other than the Class 1-LTR, Class 1-AR, and Class 2-AR
Certificates, will represent ownership of one or more regular interests. Each of
the Class 1-LTR, Class 1-AR, and Class 2-AR Certificates will represent
ownership of the sole

                                     S-107



residual interest in a REMIC. All prospective investors should review the
discussion under "Federal Income Tax Consequences" in the accompanying
prospectus.

      The Class X Certificates will, and certain other Certificates may, be
treated as having been issued with original issue discount The prepayment
assumption that will be used for purposes of computing original issue discount,
if any, for federal income tax purposes is a CPR of 20%. No representation is
made that the Mortgage Loans will, in fact, prepay at this rate or any other
rate.

      Under federal income tax law, a Certificateholder, beneficial owner,
financial intermediary or other recipient of a payment on behalf of a beneficial
owner may be subject to backup withholding at a rate generally equal to the
fourth lowest rate of income tax then in effect. See "Federal Income Tax
Consequences - Backup Withholding" in the accompanying prospectus for a general
discussion of the mechanics of backup withholding.

ADDITIONAL TAX CONSIDERATIONS APPLICABLE TO THE LIBOR CERTIFICATES

      In addition to representing ownership of one or more regular interests in
a REMIC, each LIBOR Certificate will represent a beneficial interest in the
right to receive payments from the Reserve Fund pursuant to the provisions of
the Pooling and Servicing Agreement. Solely for information reporting purposes,
the Securities Administrator will treat the entitlement to such payments as an
interest in interest rate cap contracts (or notional principal contracts)
written by the Class X Certificateholders in favor of the holders of the related
LIBOR Certificates (the "Interest Rate Cap Agreements"), and, under the terms of
the Pooling and Servicing Agreement, each holder of a LIBOR Certificate and the
Class X Certificateholders will agree, by virtue of their purchase of such
Certificates, to adopt a tax reporting position consistent with that
characterization. Moreover, the Reserve Fund will be treated as an "outside
reserve fund" within the meaning of Treasury Regulation Section 1.860G-2(h) that
is beneficially owned by the Class X Certificateholders. Alternative
characterizations of such rights are, however, possible. For instance, the right
to receive such payments could be classified for federal income tax purposes as
an interest in a partnership formed among the affected Certificateholders to
share cash flows from the Class X Certificates. Such an alternative
characterization would result in tax treatment of payments of Net WAC Shortfalls
that would differ from that which is described below. Prospective investors in
the LIBOR Certificates should consult their tax advisors regarding the tax
treatment of the rights of the holders of such Certificates to receive payments
in respect of Net WAC Shortfalls.

      A holder of a LIBOR Certificate must allocate its purchase price for such
Certificate between its two components -- the regular interest component and the
Interest Rate Cap Agreements component. For information reporting purposes, the
Securities Administrator will assume that, with respect to a LIBOR Certificate,
the Interest Rate Cap Agreements component will have only nominal value relative
to the value of the regular interest component. The Internal Revenue Service
could argue, however, that the Interest Rate Cap Agreements component has
significant value, and if that argument were to be sustained, the regular
interest component could be viewed as having been issued with an additional
amount of original issue discount ("OID") (which could cause the total amount of
discount to exceed a statutorily defined

                                     S-108


de minimis amount). See "Federal Income Tax Consequences -- REMIC Securities --
Taxation of Regular Interest Securities -- Original Issue Discount" in the
accompanying prospectus.

      Upon the sale, exchange, or other disposition of a LIBOR Certificate, the
holder must allocate the amount realized between the two components of such
Certificate based on the relative fair market values of those components at the
time of sale. Assuming that a LIBOR Certificate is held as a capital asset
within the meaning of Section 1221 of the Code, gain or loss on the disposition
of an interest in the Interest Rate Cap Agreements component should be capital
gain or loss, and, gain or loss on the disposition of the regular interest
component should, subject to the limitation described below, be capital gain or
loss. Except for any amounts of accrued but unrecognized market discount, and
except as provided in this paragraph, any gain or loss on the sale or exchange
of the regular interest component of a LIBOR Certificate realized by an investor
who holds such Certificate as a capital asset will be capital gain or loss and
will be long-term or short-term depending on whether the Certificate has been
held for the long-term capital gain holding period (currently more than one
year). Such gain will be treated as ordinary income (i) if the Certificate is
held as part of a conversion transaction, as described in Code Section 1258(c),
up to the amount of interest that would have accrued on the holder's net
investment in the conversion transaction at 120% of the appropriate applicable
Federal rate under Code Section 1274(d) in effect at the time the holder entered
into the transaction minus any amount previously treated as ordinary income with
respect to any prior disposition of property that was held as a part of such
transaction, (ii) in the case of a non-corporate taxpayer, to the extent such
taxpayer has made an election under Code Section 163(d)(4) to have net capital
gains taxed as investment income at ordinary income rates, or (iii) to the
extent that such gain does not exceed the excess, if any, of (a) the amount that
would have been includable in the gross income of the holder if its yield on
such Certificate were 110% of the applicable Federal rate as of the date of
purchase, over (b) the amount of income actually includable in the gross income
of such holder with respect to such Certificate. In addition, gain or loss
recognized from the sale of a LIBOR Certificate by certain banks or thrift
institutions will be treated as ordinary income or loss pursuant to Code Section
582(c). Long-term capital gains of certain non-corporate taxpayers are subject
to a lower minimum tax rate than ordinary income of such taxpayers for property
held for more than one year. The maximum tax rate for corporations is the same
with respect to both ordinary income and capital gains.

      As indicated above, a portion of the purchase price paid by a holder to
acquire a LIBOR Certificate will be attributable to the Interest Rate Cap
Agreements component of such Certificate. The portion of the overall purchase
price attributable to the Interest Rate Cap Agreements component must be
amortized over the life of such LIBOR Certificate, taking into account the
declining balance of the related regular interest component. Treasury
regulations concerning notional principal contracts provide alternative methods
for amortizing the purchase price of an interest rate cap contract. Under one
method -- the level yield constant interest method -- the price paid for an
interest rate cap contract is amortized over the life of the cap as though it
were the principal amount of a loan bearing interest at a reasonable rate.
Certificateholders are urged to consult their tax advisors concerning the
methods that can be employed to amortize the portion of the purchase price paid
for the Interest Rate Cap Agreements component of a LIBOR Certificate.

                                      S-109


      Any payments received by a holder of a LIBOR Certificate from the Reserve
Fund will be treated as periodic payments received from an interest rate cap
agreement. To the extent the sum of such periodic payments for any year exceed
that year's amortized cost of the Interest Rate Cap Agreements component, such
excess is ordinary income. If for any year the amount of that year's amortized
cost exceeds the sum of the periodic payments, such excess is allowable as an
ordinary deduction. A beneficial owner's ability to recognize a net deduction
with respect to the Interest Rate Cap Agreement component is limited under
Sections 67 and 68 of the Code in the case of (i) estates and trusts and (ii)
individuals owning an interest in such component directly or through a
"pass-through entity" (other than in connection with such individual's trade or
business). Pass-through entities include partnerships, S corporations, grantor
trusts, REMICs and non-publicly offered regulated investment companies, but do
not include estates, nongrantor trusts, cooperatives, real estate investment
trusts and publicly-offered regulated investment companies. Further, such a
beneficial owner will not be able to recognize a net deduction with respect to
the Interest Rate Cap Agreement component in computing the beneficial owner's
alternative minimum tax liability.

      The regular interest component of each LIBOR Certificate will be treated
as (i) assets described in Section 7701(a)(19)(C) of the Internal Revenue Code
of 1986, as amended (the "Code") and (ii) "real estate assets" under Section
856(c)(4)(A) of the Code, in the same proportion that the assets of the Trust
Fund, exclusive of the Reserve Fund, would be so treated. The Interest Rate Cap
Agreements component of the LIBOR Certificates 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.

ADDITIONAL TAX CONSIDERATIONS APPLICABLE TO THE CLASS X CERTIFICATES

      For federal income tax purposes, the Class 1-XA Certificates will
represent (i) ownership of a REMIC regular interest and (ii) the obligation to
make payments on a notional principal contract benefiting the Class 1-A1 and
Class 1-A2 Certificateholders.

      For federal income tax purposes, the Class 1-XB Certificates will
represent (i) ownership of a REMIC regular interest and (ii) the obligation to
make payments on a notional principal contract benefiting the Class 1-B1 and
Class 1-B2 Certificateholders.

THE CLASS 1-AR AND CLASS 2-AR CERTIFICATES

      Special tax considerations apply to an investment in the Class 1-AR and
Class 2-AR Certificates. In certain circumstances, the Class 1-AR and Class 2-AR
Certificates can produce a significantly less favorable after-tax return for a
beneficial owner than would be the case if (i) the Class 1-AR and Class 2-AR
Certificates were taxable as a debt instrument, or (ii) no portion of taxable
income allocated to the Class 1-AR or Class 2-AR Certificates were "excess
inclusion" income. See "Federal Income Tax Consequences -- REMIC Securities --
Taxation of Holders of Residual Interest Securities" in the prospectus.

      Under applicable Treasury regulations, if a Class 1-AR or Class 2-AR
Certificate is a "noneconomic residual interest," as described in the
prospectus, the transfer of a Class 1-AR or Class 2-AR Certificate to a U.S.
Person will be disregarded for all federal tax purposes unless no

                                      S-110


significant purpose of the transfer was to impede the assessment of collection
of tax. The prospectus describes a safe harbor set out under existing
regulations under which certain transfers of the Class 1-AR or Class 2-AR
Certificates would be presumed not to have a significant purpose of impeding the
assessment or collection of tax. See "Federal Income Tax Consequences -- REMIC
Securities -- Taxation of Holders of Residual Interest Securities --
Restrictions on Ownership and Transfer of Residual Interest Securities" in the
prospectus. Under final regulations issued by the Treasury Department on July
19, 2002 (the "Final Regulations") a transfer of a noneconomic residual interest
will not qualify under this safe harbor unless either (a) the present value of
the anticipated tax liabilities associated with holding the residual interest
does not exceed the present value of the sum of (i) any consideration given to
the transferee to acquire the interest, (ii) expected future distributions on
the interest, and (iii) any anticipated tax savings associated with holding the
interest as the REMIC generates losses, or (b) the transfer is to certain
domestic taxable corporations with sufficient amounts of both gross and net
assets where an agreement is made that all future transfers will be to taxable
domestic corporations in transactions that qualify for one of the "safe harbor"
provisions. Part (b) of this safe harbor is not available if the facts and
circumstances known to the transferor reasonably indicate that the taxes
associated with the non-economic residual interest will not be paid. In
addition, under the Final Regulations, the safe harbor applies only if the
transferee represents that income from the Class 1-AR or Class 2-AR Certificate
will not be attributed to a foreign permanent establishment or fixed base of the
transferee or another U.S. taxpayer. The Final Regulations apply to transfers of
non-economic residual interests on or after August 19, 2002, and thus will apply
to transfers of the Class 1-AR or Class 2-AR Certificates. The Final Regulations
contain additional detail regarding their application, and prospective investors
in the Class 1-AR or Class 2-AR Certificates should consult their own tax
advisors regarding the application of the Final Regulations to a transfer of the
Class 1-AR or Class 2-AR Certificates.

TAX RETURN DISCLOSURE REQUIREMENTS

      Recent legislation and Treasury Department pronouncements directed at
abusive tax shelter activity appear to apply to transactions not conventionally
regarded as tax shelters. Taxpayers are required to report certain information
on Internal Revenue Service Form 8886 if they participate in a "reportable
transaction" (as defined under Section 6011 of the Code). Pursuant to recent
legislation, a penalty in the amount of $10,000 in the case of a natural person
and $50,000 in any other case is imposed on any taxpayer that fails to file
timely an information return with the IRS with respect to a "reportable
transaction." The rules defining "reportable transactions" are complex. In
general, among other categories of transactions, they include transactions that
result in certain losses that exceed threshold amounts and transactions that
result in certain differences between the taxpayer's tax treatment of an item
and book treatment of that same item. Holders of Offered Certificates are
advised to consult their own tax advisers regarding any possible disclosure
obligations in light of their particular circumstances.

                                  ERISA MATTERS

      The Employee Retirement Income Security Act of 1974, as amended ("ERISA")
and Section 4975 of the Code impose requirements on certain employee benefit
plans -- and on certain other retirement plans and arrangements, including
individual retirement accounts and

                                      S-111


annuities, Keogh plans and collective investment funds and separate accounts in
which plans, accounts or arrangements are invested -- and on persons who are
fiduciaries with respect to these types of plans and arrangements (together,
"Plans").

      ERISA prohibits "parties in interest" with respect to a Plan from engaging
in certain transactions involving the Plan and its assets unless a statutory,
regulatory or administrative exemption applies to the transaction. Section 4975
of the Code imposes certain excise taxes on prohibited transactions involving
plans described under that section; ERISA authorizes the imposition of civil
penalties for prohibited transactions involving plans not covered under Section
4975 of the Code. Any Plan fiduciary which proposes to cause a Plan to acquire
any of the Offered Certificates should consult with its counsel with respect to
the potential consequences under ERISA and the Code of the Plan's acquisition
and ownership of such Certificates. See "ERISA Considerations" in the
accompanying prospectus.

      Certain employee benefit plans, including governmental plans and certain
church plans, are not subject to ERISA's requirements. Accordingly, assets of
those plans may be invested in the Offered Certificates without regard to the
ERISA considerations described in this prospectus supplement and in the
accompanying prospectus, subject to the provisions of other applicable federal
and state law. Any such plan which is qualified and exempt from taxation under
Sections 401(a) and 501(a) of the Code may nonetheless be subject to the
prohibited transaction rules set forth in Section 503 of the Code.

      Investments by Plans that are subject to ERISA are subject to ERISA's
general fiduciary requirements, including the requirement of investment prudence
and diversification and the requirement that a Plan's investments be made in
accordance with the documents governing the Plan. A fiduciary which decides to
invest the assets of a Plan in the Offered Certificates should consider, among
other factors, the extreme sensitivity of the investments to the rate of
principal payments (including prepayments) on the Mortgage Loans.

      The U.S. Department of Labor has granted to Morgan Stanley & Co.
Incorporated and to NationsBank Corporation (predecessor in interest to Bank of
America Corporation, an affiliate of Banc of America Securities LLC) Prohibited
Transaction Exemption ("PTE") 90-24 (Exemption Application No. D-8019, 55 Fed.
Reg. 20548 (1990)) and PTE 93-31 (Exemption Application No. D-9105, 58 Fed. Reg.
28620 (1993)), respectively, as most recently amended and restated by PTE
2002-41 (an administrative exemption), which exempts from the application of the
prohibited transaction rules transactions relating to:

      -     the acquisition, holding and sale by Plans of certain securities
            issued by a trust with respect to which Morgan Stanley & Co.
            Incorporated and Banc of America Securities LLC or any of their
            affiliates is the sole underwriter or the manager or co-manager of
            the underwriting syndicate, and

      -     the servicing, operation and management of such trusts,

provided that the general conditions and certain other requirements set forth in
the exemption are satisfied.

                                      S-112


      Among the conditions which must be satisfied for the exemption to apply
      are:

      -     The acquisition of the Offered Certificates by a Plan is on terms
            (including the price for the Certificates) that are at least as
            favorable to the Plan as they would be in an arm's length
            transaction with an unrelated party.

      -     The Offered Certificates acquired by the Plan have received a rating
            at the time of such acquisition that is one of the four highest
            generic rating categories from a rating agency identified in the
            exemption, such as S&P, Fitch, Inc. or Moody's.

      -     The Trustee must not be an affiliate of any other member of the
            "restricted group" (defined below in the second following
            paragraph), other than the Underwriters.

      -     The sum of all payments made to and retained by the Underwriters in
            connection with the distribution of the Offered Certificates
            represents not more than reasonable compensation for Underwriting
            the Offered Certificates; the sum of all payments made to and
            retained by the Seller and the Depositor pursuant to the assignment
            of the trust assets to the Trust Fund represents not more than the
            fair market value of such assets; the sum of all payments made to
            and retained by any Servicer represents not more than reasonable
            compensation for the Servicer's services under the related Servicing
            Agreement and reimbursements of such person's reasonable expenses in
            connection therewith.

      -     The Plan investing in the Offered Certificates is an "accredited
            investor" as defined in Rule 501(a)(1) of Regulation D of the SEC
            under the Securities Act of 1933.

      The Trust Fund must also meet each of the requirements listed below:

      -     Trust Fund assets must consist solely of assets of the type that
            have been included in other investment pools.

      -     Certificates representing beneficial ownership in such other
            investment pools must have been rated in one of the four highest
            generic rating categories by a rating agency for at least one year
            prior to the Plan's acquisition of Offered Certificates.

      -     Certificates evidencing beneficial ownership in such other
            investment pools must have been purchased by investors other than
            Plans for at least one year prior to any Plan's acquisition of
            Offered Certificates.

      Moreover, the exemption provides relief from certain self-dealing/conflict
of interest prohibited transactions that may occur when the Plan fiduciary
causes a Plan to acquire indebtedness of a trust holding receivables as to which
the fiduciary (or its affiliate) is an obligor provided, among other
requirements, that:

      -     in the case of an acquisition in connection with the initial
            issuance of Certificates, at least 50% of each class of Certificates
            in which Plans have invested and at least 50%

                                      S-113


            of the aggregate interests in the trust is acquired by persons
            independent of the restricted group;

      -     such fiduciary (or its affiliate) is an obligor with respect to not
            more than 5% of the fair market value of the obligations contained
            in the trust;

      -     the Plan's investment in Offered Certificates of any class does not
            exceed 25% of all of the Certificates of that class outstanding at
            the time of the acquisition; and

      -     immediately after the acquisition, no more than 25% of the assets of
            any Plan with respect to which such person is a fiduciary are
            invested in securities representing indebtedness of one or more
            issuers containing assets sold or serviced by the same entity.

This relief does not apply to Plans sponsored by members of the "restricted
group" consisting of the Depositor, the Master Servicer, any Servicer, the
Trustee, any indemnitor or any obligor with respect to Mortgage Loans included
in the assets of the Trust Fund constituting more than 5% of the aggregate
unamortized principal balance of the assets of the Trust Fund, or any affiliate
of these parties.

      It is expected that the exemption will apply to the acquisition and
holding by Plans of the Offered Certificates (except for the Class 1-AR or Class
2-AR Certificates) and that all conditions of the exemption other than those
within the control of the investors will be met.

      The rating of a class of Offered Certificates may change. If a class of
Offered Certificates no longer has a rating of at least "BBB-," Certificates of
that class will no longer be eligible for relief under the exemption (although a
Plan that had purchased the Certificate when it had an investment-grade rating
would not be required by the exemption to dispose of it). However, certain
insurance company general accounts may be eligible to purchase Offered
Certificates pursuant to Sections I and III of Prohibited Transaction Class
Exemption ("PTCE") 95-60.

      BECAUSE THE CHARACTERISTICS OF THE CLASS 1-AR AND CLASS 2-AR CERTIFICATES
MAY NOT MEET THE REQUIREMENTS OF THE EXEMPTION DISCUSSED ABOVE OR ANY OTHER
ISSUED EXEMPTION UNDER ERISA INCLUDING PTCE 83-1, THE PURCHASE AND HOLDING OF A
CLASS 1-AR OR CLASS 2-AR CERTIFICATE BY A PLAN OR BY INDIVIDUAL RETIREMENT
ACCOUNTS OR OTHER PLANS SUBJECT TO SECTION 4975 OF THE CODE MAY RESULT IN
PROHIBITED TRANSACTIONS OR THE IMPOSITION OF EXCISE TAXES OR CIVIL PENALTIES.
CONSEQUENTLY, THE INITIAL ACQUISITION AND TRANSFER OF A CLASS 1-AR OR CLASS 2-AR
CERTIFICATE WILL NOT BE REGISTERED BY THE SECURITIES ADMINISTRATOR UNLESS THE
SECURITIES ADMINISTRATOR ON BEHALF OF THE TRUSTEE RECEIVES:

      -     a representation from the acquiror or transferee of a Class 1-AR or
            Class 2-AR Certificate to the effect that the transferee is not an
            employee benefit plan subject to section 406 of ERISA or a plan or
            arrangement subject to section 4975 of the Code,

                                      S-114


            nor a person acting on behalf of any such plan or arrangement nor
            using the assets of any such plan or arrangement to effect such
            transfer, or

      -     if the purchaser is an insurance company, a representation that the
            purchaser is an insurance company which is purchasing a Class 1-AR
            or Class 2-AR Certificate with funds contained in an "insurance
            company general account" (as such term is defined in Section V(e) of
            PTCE 95-60) and that the purchase and holding of a Class 1-AR or
            Class 2-AR Certificate are covered under Sections I and III of PTCE
            95-60; or

      -     an Opinion of Counsel satisfactory to the certificate registrar to
            the effect that the purchase and holding of such a Certificate by
            the acquiror or transferee will not constitute or result in
            prohibited transactions under Title I of ERISA or Section 4975 of
            the Code and will not subject the certificate registrar, the
            Trustee, the Master Servicer, the Depositor or the Securities
            Administrator to any obligation in addition to those undertaken in
            the Pooling and Servicing Agreement.

      Prospective Plan investors should consult with their legal advisors
concerning the impact of ERISA and the Code, the applicability of the exemption
described above and PTCE 83-1 described in the prospectus, and the potential
consequences in their specific circumstances prior to making an investment in
the Offered Certificates. Moreover, each Plan fiduciary should determine whether
under the general fiduciary standards of investment prudence and
diversification, an investment in the Offered Certificates is appropriate for
the Plan, taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.

- ----------
(1)   Indicates the initial Class Notional Amount of such interest-only class.

      The Depositor has been advised by the Underwriters that they propose
initially to offer the Offered Certificates (other than the Class 1-XA, Class
1-XB, Class 1-AR, Class 1-B3, Class 2-A1, Class 2-A2, Class 2-AR, Class 2-B1,
Class 2-B2 and Class 2-B3 Certificates) to the public at the respective offering
prices set forth on the front cover of this prospectus supplement, and to
certain dealers at those prices less a concession not in excess of the
applicable percentage of the certificate denomination for each class of such
Offered Certificates as set forth in the table below. The Underwriters may allow
and such dealers may re-allow a concession not in excess of the applicable
percentage of the certificate denomination for each of such Offered Certificates
to certain other dealers as set forth in the table below. The Underwriters may
allow and such dealers may re-allow a concession not in excess of the applicable
percentage of the certificate denomination for each of such Offered Certificates
to certain other dealers as set forth in the table below.



CLASS     SELLING CONCESSION     REALLOWANCE DISCOUNT

      After the initial public offering, the public offering prices, such
concessions and such discounts may be changed.

                                      S-116


      The Class 1-XA, Class 1-XB, Class 1-B3 and Class 1-AR Certificates will be
purchased by Morgan Stanley & Co. Incorporated and the Class 2-A1, Class 2-A2,
Class 2-B1, Class 2-B2, Class 2-B3 and Class 2-AR Certificates will be purchased
by Banc of America Securities LLC, and such Certificates are being offered by
such underwriters from time to time for sale to the public in negotiated
transactions or otherwise at varying prices to be determined at the time of
sale. In connection with the sale of these classes of Offered Certificates, the
Underwriters may be deemed to have received compensation from the Depositor in
the form of underwriting discounts.

      The Underwriters intend to make a secondary market in the Offered
Certificates, but have no obligation to do so. There can be no assurance that a
secondary market for the Offered Certificates will develop or, if it does
develop, that it will continue or that it will provide Certificateholders with a
sufficient level of liquidity of investment. The Offered Certificates will not
be listed on any national securities exchange.

      Immediately prior to the sale of the Mortgage Loans to the Depositor, some
of the Mortgage Loans were the subject of financing provided by affiliates of
the Underwriters. A portion of the proceeds from the sale of the Mortgage Loans
to the Depositor will be applied to repay such financings.

      The Depositor and the Seller have agreed to indemnify the Underwriters
against, or make contributions to the Underwriters with respect to, certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

      Expenses incurred by the Depositor in connection with this offering are
expected to be approximately $650,000.

      Morgan Stanley & Co. Incorporated, one of the Underwriters, is an
affiliate of MSCC, a servicer of a portion of the Mortgage Loans.

                                  LEGAL MATTERS

      The validity of the Certificates will be passed upon for the Depositor by
Tobin & Tobin, a professional corporation, San Francisco, California. Certain
tax matters will be passed upon for the Depositor by Chapman and Cutler LLP, San
Francisco, California. McKee Nelson LLP, Washington, D.C., will act as counsel
for the Underwriters.

                                     RATINGS

      It is a condition of the issuance of the Offered Certificates that they
receive ratings from Standard and Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc. ("S&P") and Moody's Investors Service, Inc.
("Moody's" and together with S&P, the "Rating Agencies") not lower than the
ratings set forth in the table set forth under "Summary -- Rating of the
Certificates" in this prospectus supplement.

                                      S-117


      The ratings assigned to mortgage pass-through certificates address the
likelihood of the receipt of all payments on the mortgage loans by the related
certificateholders under the agreements pursuant to which such certificates are
issued. Such ratings take into consideration the credit quality of the related
trust assets, including any credit support providers, structural and legal
aspects associated with such certificates, and the extent to which the payment
stream on the trust assets is adequate to make the payments required by such
certificates. Ratings on such certificates do not, however, constitute a
statement regarding frequency of prepayments of the mortgage loans.

      The ratings do not address the possibility that, as a result of principal
prepayments, the yield on the Offered Certificates may be lower than
anticipated.

      The ratings do not address the likelihood that any Net WAC Shortfalls or
unpaid Net WAC Shortfalls will be repaid to holders of the LIBOR Certificates.

      The ratings do not address the possibility that, as a result of Net WAC
Shortfalls, current interest otherwise payable to the Class 1-XA or Class 1-XB
Certificates will instead be used to pay such amounts to other classes of
Certificates.

      The ratings assigned to the Offered Certificates should be evaluated
independently from similar ratings on other types of securities. A rating is not
a recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the Rating Agencies.

      The Depositor has not requested a rating of the Offered Certificates by
any rating agency other than the Rating Agencies; there can be no assurance,
however, as to whether any other rating agency will rate the Offered
Certificates or, if it does, what rating would be assigned by such other rating
agency. The rating assigned by such other rating agency to the Offered
Certificates could be lower than the respective ratings assigned by the Rating
Agencies.

                        GLOBAL CLEARANCE, SETTLEMENT AND
                          TAX DOCUMENTATION PROCEDURES

      Except in certain limited circumstances, the globally offered Sequoia
Mortgage Trust 2005-4 Mortgage Pass-Through Certificates (the "Global
Certificates") will be available only in book-entry form. Investors in the
Global Certificates may hold such Global Certificates through any of DTC,
Clearstream Luxembourg or Euroclear. The Global Certificates will be tradeable
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 holding Global Certificates
through Clearstream Luxembourg and Euroclear will be conducted in the ordinary
way in accordance with their normal rules and operating procedures and in
accordance with conventional eurocertificate practice (i.e., seven calendar day
settlement).

     Secondary market trading between investors holding Global Certificates
through DTC will be conducted according to the rules and procedures applicable
to U.S. corporate debt obligations and prior collateralized mortgage certificate
issues.

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

     A holder that is not a United States person (as described below) of Global
Certificates will be subject to U.S. withholding taxes unless such holders meet
certain requirements and deliver appropriate U.S. tax documents to the
securities clearing organizations or their participants.

INITIAL SETTLEMENT

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

     Investors electing to hold their Global Certificates through DTC will
follow the settlement practices applicable to prior mortgage pass-through
certificate issues. 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 Certificates through Clearstream
Luxembourg or Euroclear accounts will follow the settlement procedures
applicable to conventional eurocertificates, except that there will be no
temporary global certificate and no "lock-up" or restricted period. Global
Certificates will be credited to the securities custody accounts on the
settlement date against payment in same-day funds.

                                      S-A-1



SECONDARY MARKET TRADING

     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.

     TRADING BETWEEN DTC PARTICIPANTS. Secondary market trading between DTC
Participants will be settled using the procedures applicable to prior
collateralized mortgage certificate issues in same-day funds.

     TRADING BETWEEN CLEARSTREAM LUXEMBOURG AND/OR EUROCLEAR PARTICIPANTS.
Secondary market trading between Clearstream Luxembourg Participants or
Euroclear Participants will be settled using the procedures applicable to
conventional eurocertificates in same-day funds.

     TRADING BETWEEN DTC SELLER AND CLEARSTREAM LUXEMBOURG OR EUROCLEAR
PURCHASER. When Global Certificates are to be transferred from the account of a
DTC Participant to the account of a Clearstream Luxembourg Participant or a
Euroclear Participant, the purchaser will send instructions to Clearstream I-1
Luxembourg or Euroclear through a Clearstream Luxembourg Participant or
Euroclear Participant at least one business day prior to settlement. Clearstream
Luxembourg or Euroclear will instruct the respective Relevant Depositary, as the
case may be, to receive the Global Certificates against payment. Payment will
include interest accrued on the Global Certificates from and including the last
coupon Distribution Date to and excluding the settlement date, on the basis of
either the actual number of days in such accrual period and a year assumed to
consist of 360 days or a 360-day year of twelve 30-day months as applicable to
the related class of Global Certificates. 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 respective Relevant
Depositary of the DTC Participant's account against delivery of the Global
Certificates. After settlement has been completed, the Global Certificates will
be credited to the respective clearing system and by the clearing system, in
accordance with its usual procedures, to the Clearstream Luxembourg
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 Certificates 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 Luxembourg or Euroclear cash debt will be valued instead as of
the actual settlement date.

     Clearstream Luxembourg 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 Luxembourg or
Euroclear. Under this approach, they may take on credit exposure to Clearstream
Luxembourg or Euroclear until the Global Certificates are credited to their
accounts one day later.

     As an alternative, if Clearstream Luxembourg or Euroclear has extended a
line of credit to them, Clearstream Luxembourg Participants or Euroclear
Participants can elect not to preposition funds and allow that credit line to be
drawn upon the finance settlement. Under this procedure, Clearstream Luxembourg
Participants or Euroclear Participants purchasing Global

                                      S-A-2



Certificates would incur overdraft charges for one day, assuming they cleared
the overdraft when the Global Certificates were credited to their accounts.
However, interest on the Global Certificates would accrue from the value date.
Therefore, in many cases the investment income on the Global Certificates earned
during that one-day period may substantially reduce or offset the amount of such
overdraft charges, although this result will depend on each Clearstream
Luxembourg 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 sending Global Certificates
to the respective European Depositary for the benefit of Clearstream Luxembourg
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.

     TRADING BETWEEN CLEARSTREAM LUXEMBOURG OR EUROCLEAR SELLER AND DTC
PURCHASER. Due to time zone differences in their favor, Clearstream Luxembourg
Participants and Euroclear Participants may employ their customary procedures
for transactions in which Global Certificates are to be transferred by the
respective clearing system, through the respective Relevant Depositary, to a DTC
Participant. The seller will send instructions to Clearstream Luxembourg or
Euroclear through a Clearstream Luxembourg Participant or Euroclear Participant
at least one business day prior to settlement. In these cases Clearstream
Luxembourg or Euroclear will instruct the respective Relevant Depositary, as
appropriate, to deliver the Global Certificates to the DTC Participant's account
against payment. Payment will include interest accrued on the Global
Certificates from and including the last coupon payment to and excluding the
settlement date on the basis of either the actual number of days in such accrual
period and a year assumed to consist of 360 days or a 360-day year of twelve
30-day months as applicable to the related class of Global Certificates. 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 payment will
then be reflected in the account of the Clearstream Luxembourg Participant or
Euroclear Participant the following day, and receipt of the cash proceeds in the
Clearstream Luxembourg Participant's or Euroclear Participant's account would be
back-valued to the value date (which would be the preceding day, I-2 when
settlement occurred in New York). Should the Clearstream Luxembourg 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
Luxembourg Participant's or Euroclear Participant's account would instead be
valued as of the actual settlement date.

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

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

                                      S-A-3



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

          (c) 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
     Luxembourg or Euroclear Participant.

CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS

     A holder that is not a "United States person" within the meaning of Section
7701(a)(30) of the Internal Revenue Code of 1986 holding a book-entry
certificate through Clearstream, Euroclear or DTC may be subject to U.S.
withholding tax at a rate of 30% unless such holder provides certain
documentation to the Trustee or to the U.S. entity required to withhold tax (the
"U.S. withholding agent") establishing an exemption from withholding. A holder
that is not a United States person may be subject to 30% withholding unless:

     I. the Securities Administrator, on behalf of the Trustee or the U.S.
withholding agent receives a statement --

          (a) from the holder on Internal Revenue Service ("IRS") Form W-8BEN
     (or any successor form) that --

               (i) is signed by the certificateholder under penalty of perjury,

               (ii) certifies that such owner is not a United States person, and
          (iii) provides the name and address of the certificateholder, or

          (b) from a securities clearing organization, a bank or other financial
     institution that holds customers' securities in the ordinary course of its
     trade or business that --

               (i) is signed under penalties of perjury by an authorized
          representative of the financial institution,

               (ii) states that the financial institution has received an IRS
          Form W-8BEN (or any successor form) from the certificateholder or that
          another financial institution acting on behalf of the
          certificateholder has received such IRS Form W-8BEN (or any successor
          form),

               (iii) provides the name and address of the certificateholder, and

               (iv) attaches the IRS Form W-8BEN (or any successor form)
          provided by the certificateholder;

     II. the holder claims an exemption or reduced rate based on a treaty and
provides a properly executed IRS Form W-8BEN (or any successor form) to the
Securities Administrator or the U.S. withholding agent;

                                      S-A-4



     III. the holder claims an exemption stating that the income is effectively
connected to a U.S. trade or business and provides a properly executed IRS Form
W-8ECI (or any successor form) to the Securities Administrator or the U.S.
withholding agent; or

     IV. the holder is a "nonwithholding partnership" and provides a properly
executed IRS Form W-8IMY (or any successor form) with all necessary attachments
to the Trustee or the U.S. withholding agent. Certain pass-through entities that
have entered into agreements with the Internal Revenue Service (for example
"qualified intermediaries") may be subject to different documentation
requirements; it is recommended that such holders consult with their tax
advisors when purchasing the Certificates.

     A holder holding book-entry certificates through Clearstream or Euroclear
provides the forms and statements referred to above by submitting them to the
person through which he holds an interest in the book-entry certificates, which
is the clearing agency, in the case of persons holding directly on the books of
the clearing agency. Under certain circumstances a Form W-8BEN, if furnished
with a taxpayer identification number, ("TIN"), will remain in effect until the
status of the beneficial owner changes, or a change in circumstances makes any
information on the form incorrect. A Form W-8BEN, if furnished without a TIN,
and a Form W-8ECI will remain in effect for a period starting on the date the
form is signed and ending on the last day of the third succeeding calendar year,
unless a change in circumstances makes any information on the form incorrect.

     In addition, all holders holding book-entry certificates through
Clearstream, Euroclear or DTC may be subject to backup withholding unless the
holder:

     I. provides a properly executed IRS Form W-8BEN, Form W-8ECI or Form
W-8IMY(or any successor forms) if that person is not a United States person;

     II. provides a properly executed IRS Form W-9 (or any substitute form) if
that person is a United States person; or

     III. is a corporation, within the meaning of Section 7701(a) of the
Internal Revenue Code of 1986, or otherwise establishes that it is a recipient
exempt from United States backup withholding.

     This summary does not deal with all aspects of federal income tax
withholding or backup withholding that may be relevant to investors that are not
"United States persons" within the meaning of Section 7701(a)(30) of the
Internal Revenue Code. Such investors are advised to consult their own tax
advisors for specific tax advice concerning their holding and disposing of the
book-entry certificates.

     The term "United States person" means (1) a citizen or resident of the
United States, (2) a corporation or partnership organized in or under the laws
of the United States or any state or the District of Columbia (other than a
partnership that is not treated as a United States person under any applicable
Treasury regulations), (3) an estate the income of which is includible in gross
income for United States tax purposes, regardless of its source, or (4) 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
authority to control all substantial decisions of the trust. Notwithstanding the
preceding sentence, to the extent provided in regulations, certain trusts in

                                      S-A-5



existence on August 20, 1996 and treated as United States persons prior to such
date that elect to continue to be so treated also will be considered United
States persons.

   by the full description of these calculations, cash flows and other
   information in this prospectus and the accompanying prospectus supplement.

- -  There are material risks associated with an investment in the securities. You

                                     TRUST

   The issuer for a particular series of securities will be a trust formed by
the depositor.

                                   DEPOSITOR

   For any series of securities, either Sequoia Mortgage Funding Corporation, a
Delaware corporation, or Sequoia Residential Funding, Inc., a Delaware

   For any series of securities, the servicer named in the related prospectus
supplement. While we refer to a single servicer in this prospectus, for a
particular series of securities there may be more than one servicer, as set
forth in the prospectus supplement, as well as a master servicer to supervise
the performance of each servicer under the related servicing agreement.

   If specified in the related prospectus supplement, the depositor may appoint
a special servicer for the series of securities.

                                    TRUSTEE

   For any series of securities, the trustee named in the prospectus supplement.

   In addition, if the trust issues bonds pursuant to a separate indenture, the
trust and the indenture will be administered by separate independent trustees.
In that case, the trust will be administered by an owner trustee and the
indenture will be administered by an indenture trustee, in each case as named in
the prospectus supplement.

                                 THE SECURITIES

   Each class or series of securities will be either:

   -  certificates representing interests in the assets of the trust related to
      a certain series; or

   -  notes or bonds which are secured by the pledge of the trust assets related
      to a certain series.

                                       4


   Each class or series of securities may have a different interest rate, which
may be a fixed or floating interest rate. The prospectus supplement will specify
the interest rate for each class or series of securities, or the initial
interest rate and the method for determining subsequent changes to the interest
rate.

   A series may include one or more classes which:

   -  are stripped of regular interest payments and entitled only to principal
      distributions, with disproportionate, nominal or no interest
      distributions;

   -  are stripped of regular principal payments and entitled only to interest
      distributions, with disproportionate, nominal or no principal
      distributions;

   -  have different terms including different interest rates and different
      timing, sequential order or priority of payments, amount of principal or
      interest or both;

   -  will not distribute accrued interest but rather will add the accrued
      interest to the note principal balance, or nominal balance, in the manner
      described in the related prospectus supplement;


   -  are senior or subordinate to one or more other classes of securities in
      respect of distributions of principal and interest and allocations of
      losses on receivables; or

   -  have a feature entitling the class to a portion of or no principal distri-
      butions for an initial period and then all or a different portion of the
      principal distributions during subsequent periods.

   A series of securities may provide that distributions of principal or
interest or both on any class may be made:
   -  upon the occurrence of specified events;

   -  in accordance with a schedule or formula; or

   -  on the basis of collections from designated portions of the related trust
      assets.

                                  TRUST ASSETS

   As specified in the prospectus supplement, the trust assets may consist of:

   -  fixed rate mortgage loans secured by senior and junior liens on one-to
      four-family residential properties;

   -  adjustable rate mortgage loans secured by senior and junior liens on one-
      to four-family residential properties;

   -  mortgage pass-through securities issued or guaranteed by Ginnie Mae,
      Fannie Mae or Freddie Mac;

   -  private mortgage-backed securities;

   -  closed-end and/or revolving home equity loans or certain balances thereof
      secured by senior and junior liens on one- to four-family residential
      properties; and

   -  other assets as described in detail elsewhere in the prospectus
      supplement.

   If the prospectus supplement specifies, the trustee may acquire additional
trust assets during a specified pre-funding period from monies in a pre-funding
account.

                                       5


                                  PAYMENT DATE

   As described in the prospectus supplement, the securities will pay principal
and/or interest on specified dates. Payment dates will occur monthly, quarterly,
or semi-annually.

                                   RECORD DATE

   The prospectus supplement will describe a date preceding the payment date, as
of which the trustee or its paying agent will fix the identity of
securityholders. Securityholders whose identities are fixed on this date will
receive payments on the next succeeding payment date.

                                COLLECTION PERIOD

   A period preceding each payment date -- for example, in the case of
monthly-pay securities, the calendar month preceding the month in which a
payment date occurs. As the prospectus supplement will more fully describe, the
servicer will remit collections received in respect of a collection period to
the related trustee prior to the related payment date.

                               CREDIT ENHANCEMENT

   As described in the prospectus supplement, credit enhancement for the trust
assets or any class of securities may include any one or more of the following:

   -  the subordination of one or more classes of the securities of such series;

   -  a limited financial guaranty policy issued by an entity named in the
      prospectus supplement;

   -  the establishment of one or more reserve accounts;

   -  the use of a cross-collateralization feature;

   -  use of a mortgage pool insurance policy;

   -  excess spread,

   -  over-collateralization;

   -  letter of credit;

   -  guaranteed investment contract;

   -  primary mortgage insurance,

   -  other pledged assets,

   -  corporate guarantees,

   -  surety bond;

   -  special hazard insurance policy;

   -  bankruptcy bond;

   -  FHA insurance or VA guarantee;

   -  any other method of credit enhancement contemplated in this prospectus
      and described in the prospectus supplement; and

   -  any combination of the foregoing.

                           REGISTRATION OF SECURITIES

   The trust may issue the securities as global securities registered in the
name of Cede & Co. as nominee of the Depository Trust Company, or another
nominee. In this case, securityholders will not receive definitive securities
representing their interests except in limited circumstances described in the
prospectus supplement.

                              OPTIONAL TERMINATION

   As described in this prospectus and the prospectus supplement, the servicer,
the depositor, or if the prospectus supplement specifies, other entities, may,
at their respective options, cause the early

                                       6


retirement or redemption of some or all of a series of securities.

                              MANDATORY TERMINATION

   As described in this prospectus and the related prospectus supplement, the
trustee, the servicer, or if the related prospectus supplement specifies, other
entities, may be required to retire early all or any portion of a series of
securities. An indenture may require these parties to solicit competitive bids
for the purchase of the trust property or otherwise.

                        FEDERAL INCOME TAX CONSEQUENCES

      The securities of each series generally will be structured, for federal
income tax purposes, as one of the following:

   -  regular interests or residual interests in a trust treated as a real
      estate mortgage investment conduit or REMIC under Sections 860A through
      860G of the Internal Revenue Code, or

   -  indebtedness issued by a real estate investment trust or its taxable
      subsidiary.

   -  You should consult your own tax advisor concerning your investment.

                              ERISA CONSIDERATIONS

   A fiduciary of a pension, profit sharing or other employee benefit plan may
wish to review with its legal advisors whether the purchase, holding or
disposition of securities could give rise to a prohibited transaction under
ERISA, or the Internal Revenue Code, and whether an exemption from the
prohibited transaction rules is available.

                                     RATINGS

   Each class of securities offered by a prospectus supplement will initially be
rated in one of the four highest rating categories of at least one nationally
recognized statistical rating agency. The ratings are not a recommendation to
purchase, hold or sell the securities and do not address the market price or
suitability of the securities for a particular investor. The ratings generally
address the likelihood of timely payment of interest and the ultimate payment of
principal on the securities by the stated maturity date. The ratings do not
generally address the rate of prepayments that may be experienced on the trust
assets or the effect on the rate of prepayments on the return of principal to
securityholders.

                                LEGAL INVESTMENT

   So long as any class of securities is rated in one of the two highest ratings
categories by at least one nationally recognized statistical rating agency, such
class of securities will generally constitute "mortgage related securities"
under the Secondary Mortgage Market Enhancement Act of 1984. There are other
restrictions on the ability of certain types of investors to purchase the
securities that prospective investors should consider.

                                       7


                                  RISK FACTORS

   INVESTORS SHOULD CONSIDER THE FOLLOWING FACTORS IN CONNECTION WITH THE
PURCHASE OF SECURITIES. YOU SHOULD ALSO CONSIDER THE RISK FACTORS DESCRIBED IN
THE PROSPECTUS SUPPLEMENT.

ABILITY TO RESELL SECURITIES MAY BE LIMITED

   No market for any of the securities will exist before they are issued. We
cannot assure you that a secondary market will develop, or if it does develop,
that it will continue. Consequently, you may not be able to sell your securities
readily or at prices that will enable you to realize your desired yield. The
market values of the securities are likely to fluctuate; these fluctuations may
be significant and could result in significant losses to you.

   The secondary market for asset-backed securities has experienced periods of
illiquidity and can be expected to do so in the future. Illiquidity can have a
severely adverse effect on the prices of securities that are especially
sensitive to prepayment, credit, or interest rate risk, or that have been
structured to meet the investment requirements of limited categories of
investors.

LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO DEPOSITOR, SELLERS, SERVICER OR
TRUSTEE

   The assets of the trust are the sole source of distributions for the
securities. The securities do not represent an interest in or obligation of the
depositor, any seller, the servicer, the trustee or any of their affiliates,
except for the limited obligations of each seller with respect to certain
breaches of its representations and warranties and of the servicer with respect
to its servicing obligations. Neither the securities nor the trust assets will
be guaranteed by or insured by any governmental agency or instrumentality, the
depositor, any seller, the servicer, the trustee or any of their affiliates,
unless so specified in the supplement. Consequently, if payments on the trust
assets are insufficient to make all payments required on the certificates you
may incur a loss on your investment.

CREDIT ENHANCEMENT MAY NOT BE SUFFICIENT TO PROTECT YOU FROM LOSSES

   Credit enhancement is intended to reduce the effect of delinquent payments or
loan losses on those classes of securities that have the benefit of the credit
enhancement. However, the amount of any credit enhancement may decline or be
depleted before the securities are paid in full. As a result, securityholders
may suffer losses. In addition, credit enhancement may not cover all potential
sources of loss, such as a loss resulting from fraud or negligence by a loan
originator or other party.

                                       8


PREPAYMENTS ARE UNPREDICTABLE AND AFFECT YIELD

   The rate of principal distributions and yield to maturity on the securities
will be directly related to the rate of principal payments on the trust assets.
For example, the rate of principal payments on the loans will be affected by the
following:

   -  the amortization schedules of the loans;

   -  the rate of principal prepayments (including partial prepayments and
      prepayments resulting from refinancing) by borrowers;

   -  liquidations or repurchases of defaulted loans by the servicer;

   -  repurchases of loans by the seller as a result of defective documentation
      or breaches of representations and warranties; and

   -  the mandatory or optional purchase by the servicer or other entity with
      such rights of all of the loans or some or all of the securities in
      connection with an optional redemption of securities or termination of the
      trust.

   The rate of principal payments on loans is influenced by a variety of
economic, geographic, social and other factors. For example, if interest rates
for similar loans fall below the interest rates on the loans in the trust, the
rate of prepayment would generally be expected to increase. Conversely, if
interest rates on similar loans rise above the interest rates on the loans, the
rate of prepayment would generally be expected to decrease.

   We cannot predict the rate at which borrowers will repay their loans. Please
consider the following:

   -  If you are purchasing a security at a discount, in particular, a
      principal-only security, your yield may be lower than expected if
      principal payments on the loans occur at a slower rate than you expected;

   -  If you are purchasing a security at a premium, in particular, an
      interest-only security, your yield may be lower than expected if principal
      payments on the loans occur at a faster rate than you expected and you
      could lose your initial investment; and

   -  The earlier a payment of principal occurs, the greater the impact on your
      yield. For example, if you purchase a security at a premium, although the
      average rate of principal payments is consistent with your expectations,
      if the rate of principal payments occurs initially at a rate higher than
      expected, which would adversely impact your yield, a subsequent reduction
      in the rate of principal payments will not offset any adverse yield
      effect.

DECLINE IN PROPERTY VALUES MAY INCREASE LOAN LOSSES

   Because your securities represent an interest in loans or are secured by
loans, your investment may be affected by a decline in property values. If the
outstanding balance of a loan and any secondary financing on the underlying
property is greater than the value of the property, there is an increased risk
of delinquency, default, foreclosure and loss. A

                                       9


decline in property values could extinguish the value of a junior lien holder's
interest in a property. Losses on such loans that are not otherwise covered by
the credit enhancement described in the prospectus supplement will be borne by
the holder of one or more classes of securities.

DELAYS IN LIQUIDATION MAY ADVERSELY AFFECT YOU

   Substantial delays may occur before defaulted loans are liquidated and the
proceeds forwarded to investors. Property foreclosure actions are regulated by
state statutes and rules and are subject to many of the delays and expenses that
characterize lawsuits if defenses or counterclaims are raised. As a result,
foreclosure actions can sometimes take several years to complete and the
liquidation proceeds may not cover the defaulted loan amount. In particular,
because the costs of liquidation do not vary based on the loan amount, the risk
of insufficient liquidation proceeds is greater with small loans. Some states
prohibit a mortgage lender from obtaining a judgment against the borrower for
amounts not covered by property proceeds if the property is sold outside of a
judicial proceeding.

   In addition, 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 servicer to liquidate the property, which could
result in a delay in payments to you.

JUNIOR LIEN PRIORITY COULD RESULT IN PAYMENT DELAYS AND LOSSES

   Loans may be secured by mortgages and deeds of trust that are junior in
priority. Junior liens receive proceeds from a sale of the related property only
after the senior liens have been paid. If the proceeds remaining after the
senior liens have been paid are insufficient to satisfy the loans, then:

   -  there may be a delay in payments to securityholders while a deficiency
      judgment against the borrower is sought; and

   -  securityholders may incur a loss if a deficiency judgment cannot be
      obtained or is not realized upon.

LOANS UNDERWRITTEN TO STANDARDS BELOW "A" QUALITY MAY RESULT IN UNEXPECTED
LOSSES

   Loans supporting a series of securities may be comprised of mortgage loans
underwritten according to standards below "A" quality (e.g., Alt-A, A minus or
subprime). Such loans may be illiquid and present greater credit and other risks
than conforming mortgage loans. In addition, such mortgage loans may lack
standardized terms and may be secured by properties which are unique and more
difficult to value than typical residential properties. Loans may have been
underwritten primarily on the basis of loan-to-value ratios or favorable credit
factors rather than on the borrower's credit standing or income ratios.
Accordingly, the potential loss experience on non "A" quality mortgage loans
supporting a series of securities may be more difficult to evaluate compared to
the experience for "A" quality or other more standardized types of residential
and mixed-use properties. Actual losses incurred on such lower quality

                                      10


mortgage loans may exceed levels of credit enhancement thought to be sufficient
to protect securityholders from risk of loss.

STATE AND FEDERAL LAWS MAY LIMIT ABILITY TO COLLECT ON LOANS

   Applicable federal and state laws regulate interest rates and other charges
and require certain disclosures. In addition, other 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. Depending on the provisions of
the applicable law and the specific facts involved, violations may limit the
ability to collect all or part of the principal of or interest on the mortgage
loans. In some cases, the borrower may be entitled to a refund of amounts
previously paid and could subject the trust to damages and administrative
enforcement.

COSTS FOR CLEANING CONTAMINATED PROPERTY MAY RESULT IN LOSSES

   Under certain state and federal laws, a contaminated property may give rise
to a lien on the property to assure the costs of cleanup. In addition these laws
may impose liability for cleanup costs on the lender if the lender was involved
in the operations of the borrower, even if the environmental damage was caused
by a prior owner. Any lien or costs attached to a contaminated property could
result in a loss to securityholders.

RATING OF THE SECURITIES DOES NOT ASSURE PAYMENT

   It will be a condition to the issuance of the securities offered hereby that
they be rated in one of the four highest rating categories by each rating agency
identified in the prospectus supplement. The ratings of the securities will be
based on, among other things, the adequacy of the value of the trust assets and
any credit enhancement. The rating should not be deemed a recommendation to
purchase, hold or sell the securities, particularly since the ratings do not
address market price or suitability for an investor. There is no assurance that
the rating assigned to a security will remain in effect over the life of that
security, as the rating may be lowered or withdrawn.

CONSEQUENCES OF OWNING BOOK-ENTRY SECURITIES

   LIMIT ON LIQUIDITY OF SECURITIES. Issuance of the securities in book-entry
form may reduce their liquidity in the secondary trading market because
investors may be unwilling to purchase securities for which they cannot obtain
physical certificates.

   LIMIT ON ABILITY TO TRANSFER OR PLEDGE. Since transactions in the book-entry
securities can be effected only through the Depository Trust Company (""DTC''),
participating organizations, indirect participants and certain banks, your
ability to transfer or pledge a book-entry security to persons or entities that
do not participate in the DTC system or otherwise to take actions in respect of
such securities, may be limited due to lack of a physical certificate.

   DELAYS IN DISTRIBUTIONS. You may experience some delay in the receipt of
distributions on book-entry securities because the distributions will be
forwarded by the trustee to DTC for DTC to credit the accounts of its
participants which will thereafter

                                      11


credit them to your account either directly or indirectly through indirect
participants, as applicable.

PAYMENTS TO AND RIGHTS OF INVESTORS ADVERSELY AFFECTED BY INSOLVENCY OF SELLERS
OR SERVICER

   Each seller and the depositor will treat the transfer of the loans from the
seller to the depositor as a sale for tax accounting purposes. The depositor and
the trust will treat the transfer of the loans from the depositor to the trust
as a sale for tax accounting purposes. If these characterizations are correct,
then if the seller were to become bankrupt, the loans would not be part of the
seller's bankruptcy estate and would not be available to the seller's creditors.
On the other hand, if the seller becomes bankrupt, its bankruptcy trustee or one
of its creditors may argue that the transfer of the loans is a pledge of the
loans as security for a borrowing rather than a sale. Such an attempt, even if
unsuccessful, could result in delays in payments to securityholders.

   In the event of a bankruptcy of the servicer, the bankruptcy trustee or
receiver may have the power to prevent the trustee or the securityholders from
appointing a successor servicer, which could result in a delay in payments to
securityholders.

TRUST ASSETS MAY NOT BE SUFFICIENT TO PAY SECURITIES

   There is no assurance that the market value of the trust assets at any time
will equal the principal amount of the securities. In addition, under any
situation in which the trust assets are required to be sold, the proceeds
generally will be paid to cover administrative costs before being paid to you.
The net proceeds may be insufficient to pay the principal and interest on the
securities.

CONCENTRATION OF LOANS COULD ADVERSELY AFFECT YOUR INVESTMENT

   Loans may be secured by properties that are concentrated in particular
geographic areas, as specified in the prospectus supplement. Consequently,
losses and prepayments on the loans and the resulting payments on the securities
may be affected significantly by changes in the housing markets and the regional
economies in these areas and by the occurrence of natural disasters in these
areas, such as earthquakes, hurricanes, tornadoes, tidal waves, mud slides,
fires and floods.

PRE-FUNDING ACCOUNTS MAY RESULT IN REINVESTMENT RISK TO INVESTORS

   Amounts remaining in any pre-funding account at the end of the related
funding period will be distributed as prepayment of principal to investors on
the distribution date immediately following the end of the funding period in the
manner specified in the related prospectus supplement. Investors will bear any
reinvestment risk resulting from such prepayment.

THE ADDITION OF SUBSEQUENT MORTGAGE COLLATERAL TO PRE-FUNDING ACCOUNTS DURING
THE FUNDING PERIOD MAY ADVERSELY AFFECT THE PERFORMANCE OF THE SECURITIES

   Although subsequent mortgage collateral must satisfy the characteristics
described in the related prospectus supplement, subsequent mortgage collateral
may have different

                                      12


characteristics, including, without limitation, a more recent origination date
than the initial mortgage collateral. As a result, the addition of subsequent
mortgage collateral to the pre-funding account may adversely Affect the
performance of the related securities.

OWNERS OF ORIGINAL ISSUE DISCOUNT SECURITIES SHOULD CONSIDER FEDERAL INCOME TAX
CONSEQUENCES

   An investor owning a security issued with original issue discount will be
required to include original issue discount in ordinary gross income for federal
income tax purposes as it accrues, in advance of receipt of the cash
attributable to such income. Accrued but unpaid interest on accrual securities
will be treated as original issue discount for this federal income tax purpose.

                                  THE DEPOSITOR

   The prospectus supplement will identify whether the depositor is Sequoia
Mortgage Funding Corporation or Sequoia Residential Funding, Inc. Sequoia
Mortgage Funding Corporation is a Delaware corporation organized on January 31,
1997 and Sequoia Residential Funding, Inc., is a Delaware corporation organized
on September 1, 1999, in each case for the limited purpose of acquiring, owning
and transferring trust assets and selling interests therein or bonds secured
thereby. Sequoia Mortgage Funding Corporation is a qualified REIT subsidiary of
Redwood Trust, Inc. Sequoia Residential Funding, Inc. is a subsidiary of RWT
Holdings, Inc. RWT Holdings, Inc. is a taxable subsidiary of Redwood Trust, Inc.
Redwood Trust, Inc. is a publicly owned real estate investment trust and is
listed on the New York Stock Exchange under the symbol "RWT". Each depositor
maintains its principal office at One Belvedere Place, Mill Valley, California
94941. The telephone number is (415) 389-7373.

   Neither the depositor nor any of the depositor's affiliates will insure or
guarantee distributions on the securities of any series.

                                    THE TRUST

GENERAL

   Either Sequoia Mortgage Funding Corporation or Sequoia Residential Funding,
Inc., the depositor, will establish a trust for each series of mortgage-backed
securities and convey to the related trustee certain assets, consisting of one
or more pools of loans as specified in the prospectus supplement. Each trust
will be created as of the first day of the month in which the securities are
issued or another date which will be specified in the prospectus supplement (the
"cut-off date"). All references in this prospectus to "pool," "certificates,"
"notes," "bonds," "securities," or "securityholders," should be deemed to apply
to one specific series, trust and prospectus supplement, unless otherwise noted.

   The certificates of a series will represent interests in the assets of the
trust related to that series and the notes of a series will be secured by the
pledge of the trust assets related to that series. The trust assets for each
series will be held by the trustee for the benefit of the related
securityholders. The securities will be entitled to payment from the

                                      13


assets of the trust or other assets pledged for the benefit of the
securityholders, as specified in the prospectus supplement, and will not be
entitled to payments in respect of the assets of any other trust established by
the depositor.

   The trust assets will be acquired by the depositor, either directly or
through affiliates, from one or more sellers which may be affiliates of the
depositor, and conveyed without recourse by the depositor to the trust. Each
seller will have originated or acquired the loans as described in the prospectus
supplement. Loans acquired by the depositor will have been originated in
accordance with the underwriting criteria described under "Loan Program -
Underwriting Standards" or as otherwise described in the prospectus supplement.

   The depositor will cause the trust assets to be assigned or pledged to the
trustee named in the prospectus supplement for the benefit of the holders of the
securities. For a fee, the servicer named in the prospectus supplement will
service the trust assets, either directly or through other servicing
institutions, or subservicers, pursuant to a pooling and servicing agreement
among the depositor, the servicer, the trustee and other entities named in the
prospectus supplement in the case of a series consisting of certificates, or
pursuant to a servicing agreement among the depositor, the servicer, the trust,
the trustee and other entities named in the prospectus supplement in the case of
a series consisting of bonds. With respect to loans serviced by the servicer
through a subservicer, the servicer will remain liable for its servicing
obligations under the related agreement as if the servicer were servicing such
loans.

   As used in this prospectus, "Agreement" means, with respect to a series
consisting of certificates, the pooling and servicing agreement, and, with
respect to a series consisting of notes or bonds, the trust agreement, the
indenture and the servicing agreement, or, in either case, such other agreements
containing comparable provisions as set forth in the prospectus supplement as
the context requires.

   With respect to each trust, prior to the initial offering of the securities,
the trust will have no assets or liabilities. No trust is expected to engage in
any activities other than acquiring, managing and holding the trust assets and
other assets specified in the prospectus supplement and the proceeds thereof,
issuing securities and making payments and distributions thereon and certain
related activities. No trust is expected to have any source of capital other
than its assets and any related credit enhancement.

   Generally, the only obligations of the depositor will be to obtain certain
representations and warranties from the sellers and to assign them to the
trustee. See "The Agreements - Assignment of the Trust Assets." The obligations
of the servicer with respect to the loans will consist principally of its
contractual servicing obligations under the related Agreement (including its
obligation to enforce the obligations of the subservicers or sellers, or both,
as more fully described in this prospectus under "Loan Program - Representations
by Sellers; Repurchases" and "The Agreements - Subservicing by Sellers" and "-
Assignment of the Trust Assets") and its obligation, if any, to make certain
cash advances in the event of delinquencies in payments on or with respect to
the loans in the amounts described in this prospectus under "Description of the
Securities - Advances." The obligations of the servicer to make advances may be

                                      14


subject to limitations, to the extent provided in this prospectus and in the
prospectus supplement.

   The following is a brief description of the assets expected to be included in
the trust. If specific information respecting the trust assets is not known at
the time the securities are offered, more general information of the nature
described below will be provided in the prospectus supplement, and specific
information will be set forth in a report on Form 8-K to be Filed with the SEC
within fifteen days after the initial issuance of the securities. A copy of the
Agreements with respect to each series of securities will be available for
inspection at the corporate trust office of the trustee. A schedule of the loans
relating to each series will be attached to the Agreement delivered to the
trustee.

THE LOANS

   The loans included in a trust will be mortgage loans or home equity loans
secured by one-to-four-family residential properties. The loans may be either
first or junior lien loans and may be either closed-end loans or revolving
credit line loans. As described in the prospectus supplement, the loans may be
underwritten to "A" quality standards or to standards below "A" quality
(e.g., Alt-A, A minus or subprime).

   The loans will have monthly payments due on the first day of each month or on
such other day of the month specified in the prospectus supplement. The payment
terms of the loans to be included in a trust will be described in the prospectus
supplement and may include any of the following features (or combination
thereof):

   -  Interest may be payable at a Fixed rate, a rate adjustable from time to
      time in relation to an index, a rate that is fixed for a period of time or
      under certain circumstances and is followed by an adjustable rate, a rate
      that otherwise varies from time to time, a rate that is convertible from
      an adjustable rate to a fixed rate, or a rate that is convertible from one
      index to another, in each case as specified in the prospectus supplement.
      Changes to an adjustable rate may be subject to periodic limitations,
      maximum rates, minimum rates or a combination of such limitations. Accrued
      interest may be deferred and added to the principal of a loan for such
      periods and under such circumstances as may be specified in the prospectus
      supplement.

   -  Principal may be payable on a level debt service basis to fully amortize
      the loan over its term, may be calculated on the basis of an assumed
      amortization schedule that is significantly longer than the original term
      to maturity or on an interest rate that is different from the loan rate or
      may not be amortized during all or a portion of the original term. Certain
      loans may provide for monthly payments of interest but no payments of
      principal for either the first five or ten years or any other period
      specified after origination. Certain loans may require payment of all or a
      substantial portion of the principal upon maturity, commonly referred to
      as a "balloon payment". Principal may include interest that has been
      deferred and added to the principal balance of the loan.

   -  Monthly payments of principal and interest may be fixed for the life of
      the loan, may increase over a specified period of time or may change from
      period to period.

                                      15


      Loans may include limits on periodic increases or decreases in the amount
      of monthly payments and may include maximum or minimum amounts of monthly
      payments.

   -  Prepayments of principal may be subject to a prepayment fee, which may be
      fixed for the life of the loan or may change over time. Certain loans may
      permit prepayments after expiration of certain periods, commonly referred
      to as "lockout periods". Other loans may permit prepayments without
      payment of a fee unless the prepayment occurs during specified time
      periods. The loans may include "due on sale" clauses which permit the
      mortgagee to demand payment of the entire loan in connection with the sale
      or certain transfers of the related property. Other loans may be assumable
      by persons meeting the then applicable standards set forth in the
      underlying loan documents.

   A trust may contain buydown loans. A buydown loan includes provisions whereby
a third party partially subsidizes the monthly payments of the borrower on the
related loan during the early years of repayment under the loan, the partial
subsidy being made from a buydown fund contributed by the third party at the
time of origination of the loan. A buydown fund will be in an amount equal
either to the discounted value or full aggregate amount of future payment
subsidies. The underlying assumption of a buydown plan is that the income of the
borrower will increase during the buydown period as a result of normal increases
in compensation and inflation, so that the borrower will be able personally to
make the full loan payments at the end of the buydown period without the
continued assistance of the partial subsidy. To the extent that this assumption
as to increased income is not fulfilled, the possibility of default on a buydown
loan is increased. The prospectus supplement will contain information with
respect to any buydown loan concerning limitations on the interest rate paid by
the borrower initially, on annual increases in the interest rate and on the
length of the buydown period.

   The real property that secures repayment of the loans is referred to in this
prospectus as the mortgaged properties. In the case of home equity loans, such
liens generally will be subordinated to one or more senior liens on the related
mortgaged properties as described in the prospectus supplement. Loans will be
secured by mortgages or deeds of trust or other similar security instruments
creating a lien on a mortgaged property. Some liens will be subordinated to one
or more senior liens on the related mortgaged properties as described in the
prospectus supplement. The properties relating to loans will consist of detached
or semi-detached one- to four-family dwelling units, townhouses, rowhouses,
individual condominium units, manufactured homes, individual units in planned
unit developments, and certain other dwelling units. Such properties may include
vacation and second homes, investment properties and dwellings situated on
leasehold estates. The loans may include cooperative apartment loans secured by
security interests in shares issued by private, nonprofit, cooperative housing
corporations and in the related proprietary lease or occupancy agreements
granting exclusive rights to occupy specific dwelling units in the cooperatives'
building. In the case of leasehold interests, the term of the leasehold will
exceed the scheduled maturity of the loan by at least five years, unless
otherwise specified in the prospectus supplement.

                                      16


The properties may be located in any one of the fifty states, the District of
Columbia, Guam, Puerto Rico or any other territory of the United States.

   Loans with certain loan-to-value ratios and/or certain principal balances may
be covered wholly or partially by primary mortgage guaranty insurance policies.
The existence, extent and duration of any such coverage will be described in the
prospectus supplement.

   Certain loans, in addition to being secured by real property, may be secured
by a security interest in a limited amount of additional collateral owned by the
borrower or a third-party guarantor. Such additional collateral may no longer be
required when the principal balance of such additional collateral mortgage loan
is reduced to a predetermined amount set forth in the related pledge agreement
or guaranty agreement, as applicable, or when the loan-to-value ratio for such
additional collateral mortgage loan is reduced to the applicable loan-to-value
ratio for such additional collateral mortgage loan by virtue of an increase in
the appraised value of the mortgaged property as determined by the related
servicer.

HOME EQUITY LOANS

   As more fully described in the prospectus supplement, interest on each
revolving credit line loan, excluding introduction rates offered from time to
time during promotional periods, is computed and payable monthly on the average
daily outstanding principal balance of such loan. Principal amounts on a
revolving credit line loan may be drawn down (up to a maximum amount as set
forth in the prospectus supplement) or repaid under each revolving credit line
loan from time to time, but may be subject to a minimum periodic payment. As
specified in the prospectus supplement, amounts borrowed under a revolving
credit line loan after the related Cut-off Date may also be transferred to the
trust and comprise part of the trust assets.

   The full amount of a closed-end loan is advanced at the origination of the
loan and generally is repayable in equal (or substantially equal) installments
so that the loan either is fully amortized at its stated maturity or, if the
loan is a balloon loan, requires the payment of all or a substantial portion of
the principal upon maturity. As more fully described in the prospectus
supplement, interest on each closed-end loan is calculated on the basis of the
outstanding principal balance of such loan multiplied by the related loan rate
thereon and further multiplied by either a fraction, the numerator of which is
the number of days in the period elapsed since the preceding payment of interest
was made and the denominator of which is the number of days in the annual period
for which interest accrues on such loan, or a fraction which is 30 over 360.
Except to the extent provided in the prospectus supplement, the original terms
to stated maturity of closed-end loans generally will not exceed 360 months.

   Under certain circumstances, under either a revolving credit line loan or a
closed-end loan, a borrower may choose an interest only payment option and is
obligated to pay only the amount of interest which accrues on the loan during
the billing cycle. An interest only payment option may be available for a
specified period before the borrower

                                      17


must begin paying at least the minimum monthly payment of a specified percentage
of the average outstanding balance of the loan.

   Each prospectus supplement will contain information to the extent then
specifically known to the depositor, with respect to the loans contained in the
pool, generally including:

   -  the aggregate outstanding principal balance and the average outstanding
      principal balance of the loans as of the applicable cut-off date;

   -  the type of property securing the loan (e.g., single family residences,
      individual units in condominium apartment buildings, two- to four-family
      dwelling units, other real property or home improvements);

   -  the original terms to maturity of the loans;

   -  the largest principal balance of any of the loans;

   -  the smallest principal balance of any of the loans;

   -  the earliest origination date and latest maturity date of any of the
      loans;

   -  the loan-to-value ratios or combined loan-to-value ratios, as applicable,
      of the loans;

   -  the loan rates or annual percentage rates or range of loan rates or annual
      percentage rates borne by the loans;

   -  the maximum and minimum per annum loan rates; and

   -  the geographical location of real property related to the loans.

   If specific information regarding the loans is not known to the depositor at
the time the related securities are initially offered, more general information
of the nature described above will be provided in the prospectus supplement, and
specific information will be set forth in a report filed on Form 8-K to be filed
with the SEC within 15 days of initial issuance of the securities.

   The loan-to-value ratio of a loan at any given time is the fraction,
expressed as a percentage, the numerator of which is the principal balance of
the loan and the denominator of which is the collateral value of the property.
The combined loan-to-value ratio of a loan at any given time is the ratio,
expressed as a percentage, of (i) the sum of (a) the principal balance of the
loan and (b) the outstanding principal balance of any senior mortgage loan(s) to
(ii) the collateral value of the property. The effective loan-to-value ratio of
a loan at any given time is the fraction, expressed as a percentage, the
numerator of which is the principal balance of the loan, less the amount secured
by additional collateral, if any, and the denominator of which is the collateral
value of the property.

   The "collateral value" of a property, other than with respect to certain
loans the proceeds of which were used to refinance an existing mortgage loan
(each, a "reFinance loan"), is the lesser of (a) the appraised value
determined in an appraisal obtained at origination of such loan and (b) the
sales price for the property if the proceeds of the

                                      18


loan are used to purchase the related property. In the case of a refinance loan,
the collateral value of the related property is the appraised value of the
property as determined by an appraisal obtained at the time of refinancing.

   No assurance can be given that collateral values of the properties have
remained or will remain at the levels at which they are originally calculated.
If the residential real estate market should experience an overall decline in
property values such that the sum of the outstanding principal balances of the
loans and any primary or secondary financing on the properties, as applicable,
in a particular pool become equal to or greater than the value of the
properties, the actual rates of delinquencies, foreclosures and losses
experienced with respect to that pool could be higher than those now generally
experienced in the mortgage lending industry. In addition, adverse economic
conditions and other factors (which may or may not affect real property values)
may affect the timely payment by borrowers of scheduled payments of principal
and interest on the loans and, accordingly, the actual rates of delinquencies,
foreclosures and losses with respect to any pool. To the extent that such losses
are not covered by subordination provisions or alternative arrangements, such
losses will be borne by the securityholders of the affected series to the extent
that the credit enhancement provisions relating to the series do not protect the
securityholders from such losses.

AGENCY SECURITIES

   GINNIE MAE. Ginnie Mae, formerly the Government National Mortgage
Association, is a wholly-owned corporate instrumentality of the United States
within the Department of Housing and Urban Development. Section 306(g) of Title
II of the National Housing Act of 1934, as amended, authorizes Ginnie Mae to
guarantee the timely payment of the principal of and interest on certificates
which represent an interest in a pool of FHA loans, which are mortgage loans
insured by the FHA under the National Housing Act or under Title V of the
Housing Act of 1949, or VA loans, which are mortgage loans partially guaranteed
by the VA under the Servicemen's Readjustment Act of 1944, as amended, or
Chapter 37 of Title 38 of the United States Code.

   Section 306(g) of the National Housing Act provides that "the full faith and
credit of the United States is pledged to the payment of all amounts which may
be required to be paid under any guaranty under this subsection." In order to
meet its obligations under any such guarantee, Ginnie Mae may, under Section
306(d) of the National Housing Act, borrow from the United States Treasury in an
unlimited amount which is at any time sufficient to enable Ginnie Mae to perform
its obligations under its guarantee.

   GINNIE MAE CERTIFICATES. Each Ginnie Mae certificate held in a trust fund
will be a "fully modified pass-through" mortgage-backed certificate issued and
serviced by a Ginnie Mae issuer that is a mortgage banking company or other
financial concern approved by Ginnie Mae or approved by Fannie Mae as a
seller-servicer of FHA loans and/or VA loans. The Ginnie Mae certificates may be
either Ginnie Mae I certificates issued under the Ginnie Mae I program or Ginnie
Mae II certificates issued under the Ginnie Mae II program. The mortgage loans
underlying the Ginnie Mae certificates will consist of FHA loans and/or VA
loans. Each such mortgage is secured by a one- to

                                      19


four-family or multifamily residential property. Ginnie Mae will approve the
issuance of each Ginnie Mae certificate in accordance with a guaranty agreement
between Ginnie Mae and the Ginnie Mae issuer. Pursuant to its guaranty
agreement, a Ginnie Mae issuer will be required to advance its own funds in
order to make timely payments of all amounts due on each Ginnie Mae certificate,
even if the payments received by the Ginnie Mae issuer on the underlying FHA
loans or VA loans are less than the amounts due on the related Ginnie Mae
certificate.

   The full and timely payment of principal of and interest on each Ginnie Mae
certificate will be guaranteed by Ginnie Mae, which obligation is backed by the
full faith and credit of the United States. Each Ginnie Mae certificate will
have an original maturity of not more than 30 years, but may have original
maturities of substantially less than 30 years. Each Ginnie Mae certificate will
be based on and backed by a pool of FHA loans or VA loans secured by one- to
four-family residential properties and will provide for the payment by or on
behalf of the Ginnie Mae issuer to the registered holder of the Ginnie Mae
certificate scheduled monthly payments of principal and interest equal to the
registered holder's proportionate interest in the aggregate amount of the
monthly principal and interest payment on each FHA Loan or VA Loan underlying
the Ginnie Mae certificate, less the applicable servicing and guarantee fee
which together equal the difference between the interest on the FHA loan or VA
loan and the pass-through rate on the Ginnie Mae certificate. In addition, each
payment will include proportionate pass-through payments of any prepayments of
principal on the FHA loans or VA loans underlying the Ginnie Mae certificate and
liquidation proceeds in the event of a foreclosure or other disposition of any
such FHA loans or VA loans.

   If a Ginnie Mae issuer is unable to make the payments on a Ginnie Mae
certificate as they become due, it must promptly notify Ginnie Mae and request
Ginnie Mae to make the payments. Upon notification and request, Ginnie Mae will
make payments directly to the registered holder of the Ginnie Mae certificate.
In the event no payment is made by a Ginnie Mae issuer and the Ginnie Mae issuer
fails to notify and request Ginnie Mae to make the payment, the holder of the
Ginnie Mae certificate will have recourse only against Ginnie Mae to obtain
payment. The trustee or its nominee, as registered holder of the Ginnie Mae
certificates held in a trust fund, will have the right to proceed directly
against Ginnie Mae under the terms of the guaranty agreements relating to those
Ginnie Mae certificates for any amounts that are not paid when due.

   All mortgage loans underlying a particular Ginnie Mae I certificate must have
the same interest rate (except for pools of mortgage loans secured by
manufactured homes) over the term of the loan. The interest rate on a Ginnie Mae
I certificate will equal the interest rate on the mortgage loans included in the
pool of mortgage loans underlying the Ginnie Mae I certificate, less one-half
percentage point per annum of the unpaid principal balance of the mortgage
loans.

   Mortgage loans underlying a particular Ginnie Mae II certificate may have per
annum interest rates that vary from one another by up to one percentage point.
The interest rate on each Ginnie Mae II certificate will be between one-half
percentage point and one and one-half percentage points lower than the highest
interest rate on the

                                      20


mortgage loans included in the pool of mortgage loans underlying the Ginnie Mae
II certificate (except for pools of mortgage loans secured by manufactured
homes).

   Regular monthly installment payments on each Ginnie Mae certificate held in a
trust fund will be comprised of interest due as specified on the Ginnie Mae
certificate plus the scheduled principal payments on the FHA loans or VA loans
underlying the Ginnie Mae certificate due on the First day of the month in which
the scheduled monthly installments on the Ginnie Mae certificate are due.
Regular monthly installments on each Ginnie Mae certificate are required to be
paid to the trustee as registered holder by the 15th day of each month in the
case of a Ginnie Mae I certificate, and are required to be mailed to the trustee
by the 20th day of each month in the case of a Ginnie Mae II certificate. Any
principal prepayments on any FHA loans or VA loans underlying a Ginnie Mae
certificate held in a trust fund or any other early recovery of principal on
such loan will be passed through to the trustee as the registered holder of the
Ginnie Mae certificate.

   Ginnie Mae certificates may be backed by graduated payment mortgage loans or
by "buydown" mortgage loans for which funds will have been provided (and
deposited into escrow accounts) for application to the payment of a portion of
the borrowers' monthly payments during the early years of such mortgage loans.
Payments due the registered holders of Ginnie Mae certificates backed by pools
containing "buydown" mortgage loans will be computed in the same manner as
payments derived from other Ginnie Mae certificates and will include amounts to
be collected from both the borrower and the regulated escrow account. The
graduated payment mortgage loans will provide for graduated interest payments
that, during the early years of such mortgage loans, will be less than the
amount of stated interest on such mortgage loans. The interest not so paid will
be added to the principal of the graduated payment mortgage loans and, together
with interest thereon, will be paid in subsequent years. The obligations of
Ginnie Mae and of a Ginnie Mae issuer will be the same irrespective of whether
the Ginnie Mae certificates are backed by graduated payment mortgage loans or
"buydown" mortgage loans. No statistics comparable to the FHA's prepayment
experience on level payment, non-"buydown" mortgage loans are available in
respect of graduated payment or "buydown" mortgages. Ginnie Mae certificates
related to a series of certificates may be held in book-entry form.

   If specified in a prospectus supplement, Ginnie Mae certificates may be
backed by multifamily mortgage loans having the characteristics specified in the
prospectus supplement.

   FREDDIE MAC. Freddie Mac, formerly the Federal Home Loan Mortgage
Corporation, is a shareholder-owned, government sponsored enterprise created
pursuant to Title III of the Emergency Home Finance Act of 1970, as amended.
Freddie Mac was established primarily for the purpose of increasing the
availability of mortgage credit for the financing of urgently needed housing. It
seeks to provide an enhanced degree of liquidity for residential mortgage
investments primarily by assisting in the development of secondary markets for
conventional mortgages. The principal activity of Freddie Mac currently consists
of the purchase of first lien conventional mortgage loans, or

                                      21


participation interests in the mortgage loans, and the sale of the mortgage
loans or participations so purchased in the form of mortgage securities,
primarily Freddie Mac certificates. Freddie Mac is confined to purchasing, so
far as practicable, mortgage loans that it deems to be of such quality, type and
class as to meet generally the purchase standards imposed by private
institutional mortgage investors.

   FREDDIE MAC CERTIFICATES. Each Freddie Mac certificate represents an
undivided interest in a pool of mortgage loans that may consist of first lien
conventional loans, FHA loans or VA loans. Freddie Mac certificates are sold
under the terms of a mortgage participation certificate agreement. A Freddie Mac
certificate may be issued under either Freddie Mac's Cash Program or its
Guarantor Program.

   Mortgage loans underlying the Freddie Mac certificates held by a trust fund
will consist of mortgage loans with original terms to maturity of from ten to 40
years. Each such mortgage loan must meet the applicable standards set forth in
the legislation that established Freddie Mac. The pool of loans backing a
Freddie Mac certificate may include whole loans, participation interests in
whole loans and undivided interests in whole loans and/or participations
comprising another Freddie Mac pool. Under the Guarantor Program, however, the
pool of loans backing a Freddie Mac certificate may include only whole loans or
participation interests in whole loans.

   Freddie Mac guarantees to each registered holder of a Freddie Mac certificate
the timely payment of interest on the underlying mortgage loans to the extent of
the applicable certificate rate on the registered holder's pro rata share of the
unpaid principal balance outstanding on the underlying mortgage loans
represented by that Freddie Mac certificate, whether or not received. Freddie
Mac also guarantees to each registered holder of a Freddie Mac certificate that
the holder will collect all principal on the underlying mortgage loans, without
any offset or deduction, to the extent of such holder's pro rata share thereof,
but does not, except if and to the extent specified in the related prospectus
supplement for a series of certificates, guarantee the timely payment of
scheduled principal. Under Freddie Mac's Gold PC Program, Freddie Mac guarantees
the timely payment of principal based on the difference between the pool factor,
published in the month preceding the month of distribution, and the pool factor
published in such month of distribution. Pursuant to its guarantees, Freddie Mac
indemnifies holders of Freddie Mac certificates against any diminution in
principal by reason of charges for property repairs, maintenance and
foreclosure. Freddie Mac may remit the amount due on account of its guaranty of
collection of principal at any time after default on an underlying mortgage
loan, but not later than (i) 30 days following foreclosure sale, (ii) 30 days
following payment of the claim by any mortgage insurer or (iii) 30 days
following the expiration of any right of redemption, whichever occurs later, but
in any event no later than one year after demand has been made upon the
mortgagor for accelerated payment of principal. In taking actions regarding the
collection of principal after default on the mortgage loans underlying Freddie
Mac certificates, including the timing of demand for acceleration, Freddie Mac
reserves the right to exercise its judgment with respect to the mortgage loans
in the same manner as for mortgage loans which it has purchased but not sold.
The length of time necessary for Freddie Mac to determine that a mortgage loan
should be accelerated varies with the

                                      22


particular circumstances of each mortgagor, and Freddie Mac has not adopted
standards which require that the demand be made within any specified period.

   Freddie Mac certificates are not guaranteed by the United States or by any
Federal Home Loan Bank and do not constitute debts or obligations of the United
States or any Federal Home Loan Bank. The obligations of Freddie Mac under its
guarantee are obligations solely of Freddie Mac and are not backed by, or
entitled to, the full faith and credit of the United States. If Freddie Mac were
unable to satisfy such obligations, distributions to holders of Freddie Mac
certificates would consist solely of payments and other recoveries on the
underlying mortgage loans and, accordingly, monthly distributions to holders of
Freddie Mac certificates would be affected by delinquent payments and defaults
on such mortgage loans.

   Registered holders of Freddie Mac certificates are entitled to receive their
monthly pro rata share of all principal payments on the underlying mortgage
loans received by Freddie Mac, including any scheduled principal payments, full
and partial repayments of principal and principal received by Freddie Mac by
virtue of condemnation, insurance, liquidation or foreclosure, and repurchases
of the mortgage loans by Freddie Mac or the seller thereof. Freddie Mac is
required to remit each registered Freddie Mac Certificateholder's pro rata
share of principal payments on the underlying mortgage loans, interest at the
Freddie Mac pass-through rate and any other sums such as prepayment fees, within
60 days of the date on which those payments are deemed to have been received by
Freddie Mac.

   Under Freddie Mac's Cash Program, there is no limitation on the amount by
which interest rates on the mortgage loans underlying a Freddie Mac certificate
may exceed the pass-through rate on the Freddie Mac certificate. Under this
program, Freddie Mac purchases groups of whole mortgage loans from sellers at
specified percentages of their unpaid principal balances, adjusted for accrued
or prepaid interest, which, when applied to the interest rate of the mortgage
loans and participations purchased, results in the yield (expressed as a
percentage) required by Freddie Mac. The required yield, which includes a
minimum servicing fee retained by the servicer, is calculated using the
outstanding principal balance. The range of interest rates on the mortgage loans
and participations in a particular Freddie Mac pool under the Cash Program will
vary since mortgage loans and participations are purchased and assigned to a
Freddie Mac pool based upon their yield to Freddie Mac rather than on the
interest rate on the underlying mortgage loans. Under Freddie Mac's Guarantor
Program, the pass-through rate on a Freddie Mac certificate is established based
upon the lowest interest rate on the underlying mortgage loans, minus a minimum
servicing fee and the amount of Freddie Mac's management and guaranty income as
agreed upon between the related seller and Freddie Mac.

   Freddie Mac certificates duly presented for registration of ownership on or
before the last business day of a month are registered effective as of the First
day of the month. The First remittance to a registered holder of a Freddie Mac
certificate will be distributed so as to be received normally by the 15th day of
the second month following the month in which the purchaser becomes a registered
holder of Freddie Mac certificates.

                                      23


Thereafter, such remittance will be distributed monthly to the registered holder
so as to be received normally by the 15th day of each month. The Federal Reserve
Bank of New York maintains book-entry accounts with respect to Freddie Mac
certificates sold by Freddie Mac, and makes payments of principal and interest
each month to the registered Freddie Mac certificate holders in accordance with
the holders' instructions.

   FANNIE MAE. Fannie Mae, formerly the Federal National Mortgage Association,
is a federally chartered and privately owned corporation organized and existing
under the Federal National Mortgage Association Charter Act, as amended. Fannie
Mae was originally established in 1938 as a United States government agency to
provide supplemental liquidity to the mortgage market and was transformed into a
stockholder-owned and privately-managed corporation by legislation enacted in
1968.

   Fannie Mae provides funds to the mortgage market primarily by purchasing
mortgage loans from lenders, thereby replenishing their funds for additional
lending. Fannie Mae acquires funds to purchase mortgage loans from many capital
market investors that may not ordinarily invest in mortgages, thereby expanding
the total amount of funds available for housing. Operating nationwide Fannie Mae
helps to redistribute mortgage funds from capital-surplus to capital-short
areas.

   FANNIE MAE CERTIFICATES. Fannie Mae certificates are Guaranteed Mortgage
Pass-Through Certificates representing fractional undivided interests in a pool
of mortgage loans formed by Fannie Mae. Each mortgage loan must meet the
applicable standards of the Fannie Mae purchase program. Mortgage loans
comprising a pool are either provided by Fannie Mae from its own portfolio or
purchased pursuant to the criteria of the Fannie Mae purchase program.

   Mortgage loans underlying Fannie Mae certificates held by a trust fund will
consist of conventional mortgage loans, FHA loans or VA loans. Original
maturities of substantially all of the conventional, level payment mortgage
loans underlying a Fannie Mae certificate are expected to be from eight to 15
years or from 20 to 40 years. The original maturities of substantially all of
the Fixed rate level payment FHA loans or VA loans are expected to be 30 years.

   Mortgage loans underlying a Fannie Mae certificate may have annual interest
rates that vary by as much as two percentage points from one another. The rate
of interest payable on a Fannie Mae certificate is equal to the lowest interest
rate of any mortgage loan in the related pool, less a specified minimum annual
percentage representing servicing compensation and Fannie Mae's guaranty fee.
Under a regular servicing option pursuant to which the mortgagee or each other
servicer assumes the entire risk of foreclosure losses, the annual interest
rates on the mortgage loans underlying a Fannie Mae certificate will be between
25 basis points and 250 basis points greater than is its annual pass-through
rate. Under a special servicing option pursuant to which Fannie Mae assumes the
entire risk for foreclosure losses, the annual interest rates on the mortgage
loans underlying a Fannie Mae certificate will generally be between 30 basis
points and 255 basis points greater than the annual Fannie Mae certificate
pass-through rate. If specified in the related prospectus supplement, Fannie Mae
certificates may be backed by adjustable rate mortgages.

                                      24


   Fannie Mae guarantees to each registered holder of a Fannie Mae certificate
that it will distribute amounts representing the holder's proportionate share of
scheduled principal and interest payments at the applicable pass-through rate
provided for by the Fannie Mae certificate on the underlying mortgage loans,
whether or not received, and the holder's proportionate share of the full
principal amount of any foreclosed or other finally liquidated mortgage loan,
whether or not such principal amount is actually recovered. The obligations of
Fannie Mae under its guarantees are obligations solely of Fannie Mae and are not
backed by, or entitled to, the full faith and credit of the United States.
Although the Secretary of the Treasury of the United States has discretionary
authority to lend Fannie Mae up to $2.25 billion outstanding at any time,
neither the United States nor any of its agencies or instrumentalities is
obligated to Finance Fannie Mae's operations or to assist Fannie Mae in any
other manner. If Fannie Mae were unable to satisfy its obligations,
distributions to holders of Fannie Mae certificates would consist solely of
payments and other recoveries on the underlying mortgage loans and, accordingly,
monthly distributions to holders of Fannie Mae certificates would be affected by
delinquent payments and defaults on such mortgage loans.

   Fannie Mae certificates evidencing interests in pools of mortgage loans
formed on or after May 1, 1985 (other than Fannie Mae certificates backed by
pools containing graduated payment mortgage loans or mortgage loans secured by
multifamily projects) are available in book-entry form only. Distributions of
principal and interest on each Fannie Mae certificate will be made by Fannie Mae
on the 25th day of each month to the persons in whose name the Fannie Mae
certificate is entered in the books of the Federal Reserve Banks (or registered
on the Fannie Mae certificate register in the case of fully registered Fannie
Mae certificates) as of the close of business on the last day of the preceding
month. With respect to Fannie Mae certificates issued in book-entry form,
distributions will be made by wire and, with respect to fully registered Fannie
Mae certificates, distributions will be made by check.

   STRIPPED MORTGAGE-BACKED SECURITIES. Agency securities may consist of one or
more stripped mortgage-backed securities as described in this prospectus and in
the related prospectus supplement. Each agency security of this type will
represent an undivided interest in all or part of the principal distributions -
but not the interest distributions, or the interest distributions - but not the
principal distributions, or in some specified portion of the principal and
interest distributions on certain Freddie Mac, Fannie Mae or Ginnie Mae
certificates. The underlying securities will be held under a trust agreement by
Freddie Mac, Fannie Mae or Ginnie Mae, each as trustee, or by another trustee
named in the related prospectus supplement. Freddie Mac, Fannie Mae or Ginnie
Mae will guaranty each stripped agency security to the same extent as such
entity guarantees the underlying securities backing the stripped agency
security, unless otherwise specified in the related prospectus supplement.

   OTHER AGENCY SECURITIES. If specified in the related prospectus supplement, a
trust fund may include other mortgage pass-through certificates issued or
guaranteed by Freddie Mac, Fannie Mae or Ginnie Mae. The characteristics of any
such mortgage pass-through certificates will be described in the related
prospectus supplement. If

                                      25


specified in the related prospectus supplement, a combination of different types
of agency securities may be held in a trust fund.

PRIVATE MORTGAGE-BACKED SECURITIES

      GENERAL. Private mortgage-backed securities may consist of

      -  pass-through certificates or participation certificates evidencing an
         undivided interest in a pool of single family loans, home equity loans,
         multifamily loans, manufactured housing contracts or home improvement
         contracts,

      -  collateralized mortgage obligations secured by single family loans,
         home equity loans, multifamily loans, manufactured housing contracts or
         home improvement contracts, or

      -  other private mortgage-backed securities.

Private mortgage-backed securities may include stripped mortgage-backed
securities representing an undivided interest in all or a part of the principal
distributions - but not the interest distributions, or the interest
distributions - but not the principal distributions, or in some specified
portion of the principal and interest distributions on certain mortgage loans.
The private mortgage-backed securities will have been issued pursuant to a
pooling and servicing agreement, an indenture or similar agreement. Unless
otherwise specified in the related prospectus supplement, the seller/servicer of
the underlying loans will have entered into a private mortgage-backed securities
Agreement with a trustee under that agreement. The trustee or its agent, or a
custodian, will possess the mortgage loans underlying the private
mortgage-backed securities. The loans underlying the private mortgage-backed
securities will be serviced by a servicer directly or by one or more subscribers
which may be subject to the supervision of the servicer. Unless otherwise
specified in the related prospectus supplement, the private mortgage-backed
securities servicer will be a Fannie Mae- or Freddie Mac-approved servicer and,
if FHA loans underlie the private mortgage-backed securities, approved by HUD as
an FHA mortgagee.

   The private mortgage-backed securities issuer will be a financial institution
or other entity engaged generally in the business of mortgage lending, a public
agency or instrumentality of a state, local or federal government, or a limited
purpose corporation organized for the purpose of, among other things,
establishing trusts and acquiring and selling housing loans to trusts and
selling beneficial interests in trusts. If specified in the related prospectus
supplement, the issuer may be an affiliate of the depositor. The obligations of
the PLS issuer will generally be limited to certain representations and
warranties with respect to the assets it conveys to the related trust. Unless
otherwise specified in the related prospectus supplement, the PLS issuer will
not have guaranteed any of the assets conveyed to the related trust or any of
the private mortgage-backed securities issued under the PLS agreement.
Additionally, although the loans underlying the private mortgage-backed
securities may be guaranteed by an agency or instrumentality of the United
States, the private mortgage-backed securities themselves will not be so
guaranteed, unless the related prospectus supplement specifies otherwise.

                                      26


   Distributions of principal and interest will be made on the private
mortgage-backed securities on the dates specified in the related prospectus
supplement. The private mortgage-backed securities may be entitled to receive
nominal or no principal distributions or nominal or no interest distributions.
Principal and interest distributions will be made on the private mortgage-backed
securities by the trustee or the servicer. The issuer or the servicer may have
the right to repurchase assets underlying the private mortgage-backed securities
after a particular date or under other circumstances specified in the related
prospectus supplement.

   UNDERLYING LOANS. The loans underlying the private mortgage-backed securities
may consist of Fixed rate, level payment, fully amortizing loans or graduated
payment mortgage loans, buydown loans, adjustable rate mortgage loans, or loans
having balloon or other special payment features. The loans may be secured by
one- to four-family residential property, small mixed-use property, Five- to
eight-family residential property, multifamily property, manufactured homes or
by an assignment of the proprietary lease or occupancy agreement relating to a
specific dwelling within a cooperative and the related shares issued by the
cooperative.

   CREDIT SUPPORT RELATING TO PRIVATE MORTGAGE-BACKED SECURITIES. Credit support
in the form of reserve funds, subordination of other private mortgage-backed
securities issued under the private mortgage-backed securities agreement,
letters of credit, surety bonds, insurance policies or other types of credit
support may be provided with respect to the loans underlying the private
mortgage-backed securities or with respect to the private mortgage-backed
securities themselves.

   ADDITIONAL INFORMATION. If the trust fund for a series of securities includes
private mortgage-backed securities, the related prospectus supplement will
generally specify

   -  the aggregate approximate principal amount and type of private
      mortgage-backed securities to be included in the trust fund,

   -  the maximum original term-to-stated maturity of the private
      mortgage-backed securities,

   -  the weighted average term-to-stated maturity of the private
      mortgage-backed securities,

   -  the pass-through or certificate rate of the private mortgage-backed
      securities,

   -  the weighted average pass-through of interest rate of the private
      mortgage-backed securities,

   -  the issuer, the servicer (if other than the issuer) and the trustee,

   -  certain characteristics of any credit support such as reserve funds,
      insurance policies, surety bonds, letters of credit or guaranties relating
      to the loans underlying the private mortgage-backed securities themselves,

   -  the terms on which the loans underlying the private mortgage-backed
      securities may, or are required to, be purchased prior to their stated
      maturity or the stated maturity of the private mortgage-backed securities,
      and

                                      27


   -  the terms on which mortgage loans may be substituted for those originally
      underlying the private mortgage-backed securities.

   In addition, the related prospectus supplement will provide information about
the loans which comprise the underlying assets of the private mortgage-backed
securities, generally including

   -  the payment features of the mortgage loans,

   -  the approximate aggregate principal balance, if known, of underlying loans
      insured or guaranteed by a governmental entity,

   -  the servicing fee or range of servicing fees with respect to the loans,
      and

   -  the minimum and maximum stated maturities of the underlying loans at
      origination.

SUBSTITUTION OF TRUST ASSETS

   Substitution of trust assets may be permitted in the event of breaches of
representations and warranties with respect to certain trust assets or in the
event the documentation with respect to any trust asset is determined by the
trustee to be incomplete or as further specified in the prospectus supplement.
The period during which such substitution will be permitted generally will be
indicated in the prospectus supplement.

                                USE OF PROCEEDS

   The net proceeds to be received from the sale of the securities will be
applied by the depositor to the purchase of trust assets or will be used by the
depositor for general corporate purposes. The depositor expects to sell
securities in series from time to time, but the timing and amount of offerings
of securities will depend on a number of factors, including the volume of trust
assets acquired by the depositor, prevailing interest rates, availability of
funds and general market conditions.

                                  LOAN PROGRAM

   The loans will have been purchased by the depositor, either directly or
through affiliates, from sellers. Unless otherwise specified in the prospectus
supplement, the loans acquired by the depositor will have been originated in
accordance with the underwriting criteria described below.

UNDERWRITING STANDARDS

   Each seller will represent and warrant that all loans originated and/or sold
by it to the depositor will have been underwritten in accordance with standards
described in the prospectus supplement.

   Underwriting standards are applied by or on behalf of a lender to evaluate
the borrower's credit standing and repayment ability, and the value and adequacy
of the related property as collateral. In general, a prospective borrower
applying for a mortgage loan is required to fill out a detailed application
designed to provide to the underwriting

                                      28


officer pertinent credit information. As part of the description of the
borrower's financial condition, the borrower generally is required to provide a
current list of assets and liabilities and a statement of income and expenses,
as well as an authorization to apply for a credit report which summarizes the
borrower's credit history with local merchants and lenders and any record of
bankruptcy or other significant public records. In most cases, an employment
verification is obtained from an independent source (typically the borrower's
employer), which verification reports the length of employment with that
organization, the borrower's current salary and whether it is expected that the
borrower will continue such employment in the future. If a prospective borrower
is self-employed, the borrower may be required to submit copies of signed tax
returns. The borrower may also be required to authorize verification of deposits
at financial institutions where the borrower has demand or savings accounts.

   In determining the adequacy of the property as collateral, an appraisal will
generally be made of each property considered for Financing. The appraiser is
required to inspect the property and verify that it is in good repair and that
construction, if new, has been completed. The appraisal is based on the market
value of comparable homes, the estimated rental income (if considered applicable
by the appraiser) and the cost of replacing the home.

   Once all applicable employment, credit and property information is received,
a determination generally is made as to whether the prospective borrower has
sufficient monthly income available:

   -  to meet the borrower'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 property (such as
      property taxes and hazard insurance), and

   -  to meet monthly housing expenses and other financial obligations and
      monthly living expenses.

The underwriting standards applied by a seller, particularly with respect to the
level of loan documentation and the borrower's income and credit history, may be
varied in appropriate cases where factors such as low combined loan-to-value
ratios or other favorable credit aspects exist.

   If specified in the prospectus supplement, a portion of the loans in the pool
may have been originated under a limited documentation program. Under a limited
documentation program, more emphasis is placed on the value and adequacy of the
property as collateral and other assets of the borrower than on credit
underwriting. Under a limited documentation program, certain credit underwriting
documentation concerning income or income verification and/or employment
verification is waived. The prospectus supplement will indicate the types of
limited documentation programs pursuant to which the loans were originated and
the underwriting standards applicable to such limited documentation programs.

   In the case of a loan secured by a leasehold interest in real property, the
title to which is held by a third party lessor, the seller will represent and
warrant, among other

                                      29


things, that the remaining term of the lease and any sublease is at least Five
years longer than the remaining term on the related mortgage note.

   Certain of the types of loans that may be included in a trust may involve
additional uncertainties not present in traditional types of loans. For example,
certain of such loans may provide for escalating or variable payments by the
borrower. These types of loans are underwritten on the basis of a judgment that
the borrowers have the ability to make the monthly payments required initially.
In some instances, however, a borrower's income may not be sufficient to permit
continued loan payments as such payments increase. These types of loans may also
be underwritten primarily upon the basis of combined loan-to-value ratios or
other favorable credit factors.

QUALIFICATIONS OF SELLERS

   Each seller must be an institution experienced in originating and servicing
loans of the type contained in the pool in accordance with accepted practices
and prudent guidelines, and must maintain satisfactory facilities to originate
and service those loans. Each seller must be a seller/servicer approved by
either Fannie Mae or Freddie Mac. Each seller must be a mortgagee approved by
the FHA or an institution the deposit accounts of which are insured by the
Federal Deposit Insurance Corporation.

QUALITY CONTROL

   A quality control program has been developed to monitor the quality of loan
underwriting at the time of acquisition and on an ongoing basis. All loans
purchased will be subject to this quality control program. A legal document
review of each loan acquired will be conducted to verify the accuracy and
completeness of the information contained in the mortgage notes, security
instruments and other pertinent documents in the file. A sample of loans to be
acquired, selected by focusing on those loans with higher risk characteristics,
will normally be submitted to a third party nationally recognized underwriting
review firm for a compliance check of underwriting and review of income, asset
and appraisal information.

REPRESENTATIONS BY SELLERS; REPURCHASES

   Each seller will have made representations and warranties in respect of the
loans sold by such seller and evidenced by all, or a part, of a series of
securities. Such representations and warranties may include, among other things:

   -  that title insurance (or in the case of properties located in areas where
      such policies are generally not available, an attorney's certificate of
      title) and any required hazard insurance policy were effective at
      origination of each loan and that each policy (or certificate of title as
      applicable) remained in effect on the date of purchase of the loan from
      the seller by or on behalf of the depositor;

   -  that the seller had good title to each such loan and such loan was subject
      to no offsets, defenses, counterclaims or rights of rescission except to
      the extent that any buydown agreement may forgive certain indebtedness of
      a borrower;

                                      30


   -  that each loan constituted a valid lien on, or a perfected security
      interest with respect to, the property (subject only to permissible liens
      disclosed, if applicable, title insurance exceptions, if applicable, and
      certain other exceptions described in the Agreement) and that the property
      was free from damage and was in acceptable condition;

   -  that there were no delinquent tax or assessment liens against the
      property;

   -  that no required payment on a loan was delinquent more than the number of
      days specified in the prospectus supplement; and

   -  that each loan was made in compliance with, and is enforceable under, all
      applicable state and federal laws and regulations in all material
      respects.

   The servicer or the trustee will promptly notify the relevant seller of any
breach of any representation or warranty made by it in respect of a loan which
materially and adversely affects the interests of the securityholders in such
loan. Unless otherwise specified in the prospectus supplement, if such seller
cannot cure such breach within the time period specified in the prospectus
supplement following notice from the servicer or the trustee, as the case may
be, then such seller will be obligated to repurchase such loan from the trust at
a purchase price equal to 100% of the unpaid principal balance thereof as of the
date of the repurchase plus accrued interest thereon to the First day of the
month following the month of repurchase at the loan rate (less any advances or
amount payable as related servicing compensation if the seller is the servicer)
and may elect to substitute for such loan a replacement loan that satisfies the
criteria specified in the prospectus supplement.

   If a REMIC election is being made with respect to a trust, the servicer, the
trustee or a holder of the related residual certificate generally will be
obligated to pay any prohibited transaction tax which may arise in connection
with any such repurchase or substitution and the trustee must have received a
satisfactory opinion of counsel that any such substitution will not cause the
trust to lose its status as a REMIC or otherwise subject the trust to a
prohibited transaction tax. This repurchase or substitution obligation will
constitute the sole remedy available to holders of securities or the trustee for
a breach of representation by a seller.

   Neither the depositor nor the servicer will be obligated to purchase or
substitute a loan if a seller defaults on its obligation to do so, and no
assurance can be given that sellers will carry out their respective repurchase
or substitution obligations with respect to loans.

                          DESCRIPTION OF THE SECURITIES

   Each series of securities issued in the form of certificates will be issued
pursuant to either a pooling and servicing agreement or a trust agreement among
the depositor, the servicer and the trustee or pursuant to agreements containing
comparable provisions, as described in the prospectus supplement. A form of
pooling and servicing agreement and trust agreement have been Filed as an
exhibit to the registration statement of which this prospectus forms a part.
Each series of securities issued in the form of bonds will be

                                      31


issued pursuant to an indenture between the related trust and the entity named
in the prospectus supplement as trustee or pursuant to agreements containing
comparable provisions, as described in the prospectus supplement, and the
related loans will be serviced by the servicer pursuant to a servicing
agreement. A form of indenture and servicing agreement has been Filed as an
exhibit to the registration statement of which this prospectus forms a part.

   A series of securities may consist of both notes or bonds and certificates.
The provisions of each Agreement will vary depending upon the nature of the
securities to be issued thereunder and the nature of the trust. The following
are descriptions of the material provisions which may appear in each Agreement.
The descriptions are subject to, and are qualified in their entirety by
reference to, all of the provisions of the specific Agreement applicable to
series of securities. The depositor will provide a copy of the Agreement
(without exhibits) relating to any series without charge upon written request of
a holder of record of a security of such series addressed to the depositor, One
Belvedere Place, Mill Valley, California 94941, Attention: Secretary.

GENERAL

   Unless otherwise described in the prospectus supplement, the securities of
each series:

   -  will be issued in book-entry or fully registered form, in the authorized
      denominations specified in the prospectus supplement;

   -  will, in the case of certificates, evidence specified beneficial ownership
      interests in the assets of the trust;

   -  will, in the case of notes or bonds, be secured by the assets of the
      trust; and

   -  will not be entitled to payments in respect of the assets included in any
      other trust established by the depositor.

   Unless otherwise specified in the prospectus supplement, the securities will
not represent obligations of the depositor or any affiliate of the depositor.
Certain of the loans may be guaranteed or insured as set forth in the prospectus
supplement. Each trust will consist of, to the extent provided in the related
Agreement:

   -  the trust assets subject to the related Agreement, including all payments
      of interest and principal received with respect to the loans after the
      cut-off date;

   -  such assets as from time to time are required to be deposited in the
      related Collection Account;

   -  property which secured a loan and which is acquired on behalf of the
      securityholders by foreclosure or deed in lieu of foreclosure; and

   -  any insurance policies or other forms of credit enhancement required to be
      maintained pursuant to the related Agreement.

   If so specified in the prospectus supplement, a trust may also include one or
more of the following: reinvestment income on payments received on the trust
assets, a reserve

                                      32


account, a mortgage pool insurance policy, a special hazard insurance policy, a
bankruptcy bond, one or more letters of credit, a surety bond, guaranties, a
demand note or similar instruments.

   Each series of securities will be issued in one or more classes. Each class
of certificates of a series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on, and each class of notes of a series will be secured by, the related trust
assets. A series of securities may include one or more classes that are senior
in right to payment to one or more other classes of securities of such series.
Certain series or classes of securities may be covered by insurance policies,
surety bonds or other forms of credit enhancement, in each case as described in
the prospectus supplement. One or more classes of securities of a series may be
entitled to receive distributions of principal, interest or any combination
thereof. Distributions on one or more classes of a series of securities may be
made prior to one or more other classes, after the occurrence of specified
events, in accordance with a schedule or formula or on the basis of collections
from designated portions of the related trust assets, in each case as specified
in the prospectus supplement. The timing and amounts of such distributions may
vary among classes or over time as specified in the prospectus supplement.

   Distributions of principal and interest (or, where applicable, of principal
only or interest only) on the related securities will be made by the trustee or
the payment agent on each payment date in proportion to the percentages
described in the prospectus supplement. Payment dates will occur either monthly,
quarterly, semi-annually or at other specified intervals and will occur on the
dates as are described in the prospectus supplement. Distributions will be made
to the persons in whose names the securities are registered at the close of
business on the record date relating to payment date. Distributions will be made
in the manner described in the prospectus supplement to the persons entitled
thereto at the address appearing in the register maintained for securityholders;
provided, however, that, unless otherwise provided in the prospectus supplement,
the final distribution in retirement of the securities will be made only upon
presentation and surrender of the securities at the office or agency of the
trustee or other person specified in the notice to securityholders of such final
distribution.

   The securities will be freely transferable and exchangeable at the corporate
trust office of the trustee specified in the prospectus supplement. No service
charge will be made for any registration of exchange or transfer of securities
of any series, but the trustee may require payment of a sum sufficient to cover
any related tax or other governmental charge.

   The sale or transfer of certain classes of securities to employee benefit
plans and retirement arrangements that are subject to the provisions of Title I
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
or Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"),
may be restricted. The prospectus supplement for each series of securities will
describe any such restrictions.

                                      33


   As to each series, an election may be made to treat the related trust or
designated portions thereof as one or more REMICs as defined in the Code. The
prospectus supplement will specify whether a REMIC election is to be made.
Alternatively, the Agreement for a series of securities may provide that a REMIC
election may be made at the discretion of the depositor or the servicer and may
only be made if certain conditions are satisfied. As to any such series, the
terms and provisions applicable to the making of a REMIC election will be set
forth in the prospectus supplement. If such an election is made with respect to
a series of securities, one of the classes will be designated as evidencing the
sole class of residual interests in the REMIC. All other classes of securities
in such a series will constitute regular interests in the REMIC. As to each
series of securities with respect to which a REMIC election is to be made; the
servicer, the trustee and/or a holder of the residual certificate will be
obligated to take all actions required in order to comply with applicable laws
and regulations.

DISTRIBUTIONS ON SECURITIES

  GENERAL.

   In general, the method of determining the amount of distributions on a
particular series of securities will depend on the type of credit support, if
any, that is used with respect to such series. Set forth below are descriptions
of various methods that may be used to determine the amount of distributions on
the securities of a particular series. The prospectus supplement for each series
of securities will describe the method to be used in determining the amount of
distributions on the securities of that series.

   Distributions allocable to principal and interest on the securities will be
made by the trustee out of, and only to the extent of, funds in the related
collection account, including any funds transferred from any reserve account. As
between securities of different classes and as between distributions of
principal (and, if applicable, between distributions of principal prepayments
and scheduled payments of principal) and interest, distributions made on any
payment date will be applied as specified in the prospectus supplement. The
prospectus supplement will also describe the method for allocating distributions
among securities of a particular class.

  AVAILABLE FUNDS.

   All distributions on the securities of each series on each payment date will
be made from the available funds described below, in accordance with the terms
described in the prospectus supplement and specified in the Agreement. Available
funds for each payment date will generally equal the amount on deposit in the
related Collection Account on such payment date (net of related fees and
expenses payable by the related trust) other than amounts to be held therein for
distribution on future payment dates.

  DISTRIBUTIONS OF INTEREST.

   Interest will accrue on the aggregate principal balance of the securities
(or, in the case of securities entitled only to distributions allocable to
interest, the aggregate notional amount) of each class of securities (the
"class security balance") entitled to interest

                                      34


from the date, at the pass-through rate or interest rate, as applicable, and for
the periods specified in the related prospectus supplement. The pass-through
rate or interest rate applicable to each class of securities will be specified
in the related prospectus supplement as either a Fixed rate or adjustable rate.
Other than with respect to a class of securities that provides for interest that
accrues but is not currently payable (""accrual securities''), to the extent
funds are available for the payment of interest on a class of securities,
interest accrued during each specified period on that class of securities
entitled to interest will be distributable on the payment dates specified in the
prospectus supplement until the aggregate class security balance of those
securities has been distributed in full or, in the case of securities entitled
only to distributions allocable to interest, until the aggregate notional amount
of those securities is reduced to zero or for the period of time designated in
the prospectus supplement. Except in the case of the accrual securities, the
original class security balance of each security will equal the aggregate
distributions allocable to principal to which such security is entitled.
Distributions allocable to interest on each security that is not entitled to
distributions allocable to principal will be calculated based on the notional
amount of such security. The notional amount of a security will not evidence an
interest in or entitlement to distributions allocable to principal but will be
used solely for convenience in expressing the calculation of interest and for
certain other purposes.

   Interest payable on the securities of a series on a payment date will include
all interest accrued during the period specified in the prospectus supplement.
In the event interest accrues over a period ending two or more days prior to a
payment date, the effective yield to securityholders will be reduced from the
yield that would otherwise be obtainable if interest payable on the security
were to accrue through the day immediately preceding such payment date, and the
effective yield (at par) to securityholders will be less than the indicated
coupon rate.

   With respect to any class of accrual securities, as specified in the
prospectus supplement, any interest that has accrued but is not paid on a given
payment date may be added to the aggregate class security balance of such class
of securities on that payment date and thereafter may itself accrue interest as
part of the aggregate class security balance. Distributions of interest on any
class of accrual securities will commence only after the occurrence of the
events specified in such prospectus supplement. Prior to the occurrence of those
specified events, the beneficial ownership interest in the trust or the
principal balance, as applicable, of such class of accrual securities, as
reflected in the aggregate class security balance of such class of accrual
securities, will increase on each payment date by the amount of interest that
accrued on that class of accrual securities during the preceding interest
accrual period.

  DISTRIBUTIONS OF PRINCIPAL.

   The prospectus supplement will specify the method by which the amount of
principal to be distributed on the securities on each payment date will be
calculated and the manner in which such amount will be allocated among the
classes of securities entitled to distributions of principal. The aggregate
class security balance of any class of securities entitled to distributions of
principal generally will equal the aggregate original

                                      35


class security balance specified in the related prospectus supplement for that
class, reduced by all distributions allocable to principal previously made to
the holders of that class of securities and by any allocations of realized
losses to that class, and, in the case of accrual securities, increased by all
interest accrued but not then distributable on such accrual securities, as
specified in the prospectus supplement. The aggregate class security balance for
adjustable rate securities may also be subject to the effects of negative
amortization.

   If so provided in the prospectus supplement, one or more classes of
securities will be entitled to receive all or a disproportionate percentage of
the principal prepayments made with respect to a payment date in the percentages
and under the circumstances or for the periods specified in that prospectus
supplement. This allocation of principal prepayments to that class or those
classes of securities will have the effect of accelerating the amortization of
those securities while increasing the interests evidenced by one or more other
classes of securities issued by the related trust. Increasing the interests of
the other classes of securities relative to that of certain securities is
intended to preserve the availability of the subordination provided by those
other classes of securities.

  UNSCHEDULED DISTRIBUTIONS.

   If specified in the prospectus supplement, the securities will be subject to
receipt of distributions before the next scheduled payment date under the
circumstances and in the manner described below and in such prospectus
supplement. If applicable, the trustee will be required to make these
unscheduled distributions on the day and in the amount specified in the
prospectus supplement if, due to substantial payments of principal (including
principal prepayments, redemptions of securities or termination of the trust) on
the trust assets, the trustee or the servicer determines that the funds
available or anticipated to be available from the collection account and, if
applicable, any reserve account, on the next scheduled payment date may be
insufficient to make required distributions on the securities on that payment
date. Unless otherwise specified in the prospectus supplement, the amount of any
such unscheduled distribution that is allocable to principal will not exceed the
amount that would otherwise have been required to be distributed as principal on
the securities on the next payment date. Unless otherwise specified in the
prospectus supplement, the unscheduled distributions will include interest at
the applicable pass-through rate, if any, or interest rate, if any, on the
portion of the unscheduled distribution that is allocable to principal for the
period and to the date specified in the prospectus supplement.

ADVANCES

   To the extent provided in the prospectus supplement, the servicer will be
required to advance on or before each payment date (from its own funds, funds
advanced by subservicers or funds held in the collection account for future
distributions to the holders of securities of the related series) an amount
equal to the aggregate of payments of interest and/or principal that were
delinquent on the related determination date (as specified in the prospectus
supplement) and were not advanced by any subservicer,

                                      36


subject to the servicer's determination that such advances may be recoverable
out of late payments by borrowers, liquidation proceeds, insurance proceeds or
otherwise.

   In making advances, the servicer will endeavor to maintain a regular flow of
scheduled interest and principal payments to securityholders, rather than to
guarantee or insure against losses. If advances are made by the servicer from
cash being held for future distribution to securityholders, the servicer will
replace the funds advanced on or before any future payment date to the extent
that funds in the applicable collection account on that payment date would be
less than the amount required to be available for distributions to
securityholders on that date. Any funds advanced with respect to a given loan
will be reimbursable to the servicer out of recoveries on that loan (which
recoveries will include late payments made by the related borrower, any related
insurance proceeds, liquidation proceeds or proceeds of any loan purchased by
the depositor, a subservicer or a seller pursuant to the related Agreement).
Advances by the servicer (and any advances by a subservicer) also will be
reimbursable to the servicer (or subservicer) from cash otherwise distributable
to securityholders (including the holders of senior securities) to the extent
that the servicer determines that any advances previously made are not
ultimately recoverable from recoveries on the related loans.

   To the extent provided in the prospectus supplement, the servicer also will
be obligated to make advances in respect of certain taxes and insurance premiums
not paid by borrowers on a timely basis, but only to the extent those advances
would be recoverable out of insurance proceeds, liquidation proceeds or
otherwise. These advances are reimbursable to the servicer to the extent
permitted by the related Agreement. The obligations of the servicer to make
advances may be supported by a cash advance reserve account, a surety bond or
other arrangement of the type described in this prospectus under ""Credit
Enhancement,'' and in each case as described in the prospectus supplement.

   To the extent provided in the prospectus supplement, the servicer will be
required to advance all funds required for draws by borrowers under revolving
lines of credit.

   If specified in the prospectus supplement, in the event the servicer or a
subservicer fails to make a required advance, the trustee, in its capacity as
successor servicer, will be obligated to make the advance. If the trustee makes
this type of advance, it will be entitled to reimbursement to the same extent
and in the same manner that the servicer or a subservicer would have been
entitled to reimbursement if it had made the advance.

COMPENSATING INTEREST

   Payments may be received on loans in the trust which represent either a
principal prepayment in full or a principal payment which is in excess of the
scheduled monthly payment and which is not intended to cure a delinquency. If
specified in the prospectus supplement, the servicer will be required to remit
to the trustee with respect to each of these types of payments during any due
period an amount equal to either (1) the excess, if any, of (a) 30 days'
interest on the principal balance of the related loan at the loan rate net of
the per annum rate at which the servicer's servicing fee accrues, over (b) the
amount of interest actually received on the loan during the related due period,
net of the

                                      37


servicer's servicing fee or (2) such other amount as described in the prospectus
supplement. This amount remitted to the trustee by the servicer will be limited
to amounts otherwise payable to the servicer as servicing compensation.

REPORTS TO SECURITYHOLDERS

   Prior to or concurrently with each distribution on a payment date, the
servicer or the trustee will furnish to each security holder of record of the
related series a statement setting forth, to the extent applicable to such
series of securities, among other things:

   -  the amount of the distribution made on that payment date that is allocable
      to principal, separately identifying the aggregate amount of any principal
      prepayments and, if specified in the prospectus supplement, any applicable
      prepayment penalties included therein;

   -  the amount of the distribution made on that payment date that is allocable
      to interest;

   -  the amount of any advance made during the related due period;

   -  the aggregate amount (a) otherwise allocable to the subordinated
      securityholders on that payment date, and (b) withdrawn from the reserve
      account, if any, that is included in the amounts distributed to the senior
      securityholders;

   -  the outstanding principal balance or notional amount, as applicable, of
      each class of the related series after giving effect to all distributions
      of principal on that payment date;

   -  the percentage or amount of principal payments on the loans (excluding
      prepayments), if any, which each class will be entitled to receive on the
      related payment date;

   -  the percentage or amount of principal prepayments on the loans, if any,
      which each such class will be entitled to receive on the related payment
      date;

   -  the amount of the servicing compensation retained or withdrawn from the
      collection account by the servicer, and the amount of additional servicing
      compensation received by the servicer attributable to penalties, fees,
      excess liquidation proceeds and other similar charges and items;

   -  the number and aggregate principal balances of loans which are:

      -  not in foreclosure but are delinquent (A) 31 to 60 days, (B) 61 to 90

   The report to securityholders for any series of securities may include
additional or other information of a similar nature to that specified above.

   In addition, within a reasonable period of time after the end of each
calendar year, the servicer or the trustee will mail to each security holder of
record at any time during that calendar year a report of information as may be
deemed necessary or desirable for securityholders to prepare their tax returns.

CATEGORIES OF CLASSES OF SECURITIES

   The securities of any series may be comprised of one or more classes. These
classes generally fall into different categories. The following chart identifies
and generally defines certain of the more typical categories of security
classes. The prospectus supplement for a series of securities may identify the
classes which comprise that series by reference to the following categories.



CATEGORIES OF CLASSES                                DEFINITION
                                        
                                PRINCIPAL TYPES

Accretion Directed ....................    A class that receives principal
                                           payments that are funded from
                                           collections that would have otherwise
                                           funded interest payments on the
                                           accreted interest from specified
                                           accrual classes. An accretion
                                           directed class also may receive
                                           principal payments from principal
                                           paid on the trust assets.

Component Securities ..................    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 chart.

   CATEGORIES OF CLASSES                               DEFINITION
                                        
Notional Amount Securities ............    A class having no principal balance
                                           and bearing interest on the related
                                           notional amount. The notional amount
                                           is used for purposes of the
                                           determination of interest
                                           distributions.

Planned Principal Class or PACs .......    A class that is designed to receive
                                           principal payments using a
                                           predetermined principal balance
                                           schedule derived by assuming two
                                           constant prepayment rates for the
                                           trust assets. These two rates are the
                                           endpoints for the ""structuring
                                           range'' for the planned principal
                                           class. The planned principal classes
                                           in any series of securities may be
                                           subdivided into different categories
                                           (e.g., primary planned principal
                                           classes, secondary planned principal
                                           classes and so forth) having
                                           different effective structuring
                                           ranges and different principal
                                           payment priorities. The structuring
                                           range for the secondary planned
                                           principal class of a series of
                                           securities will be narrower than that
                                           for the primary planned principal
                                           class of such series.

Scheduled Principal Class .............    A class that is designated 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
                                           trust assets. Theses two rates are
                                           the endpoints for the ""structuring
                                           range'' for the scheduled principal
                                           class.

Sequential Pay ........................    Classes that receive principal
                                           payments in a prescribed sequence,
                                           that do not have predetermined
                                           principal balance schedules and that
                                           receive payments of principal, when
                                           amounts are available to make
                                           payments of principal, continuously
                                           from the First payment 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.

Strip .................................    A class that receives a constant
                                           proportion, or "strip," of the
                                           principal payments on the trust
                                           assets. The constant proportion of
                                           such principal payments may or may
                                           not vary for each trust asset
                                           included in the trust and will be
                                           calculated in the manner described in
                                           the prospectus supplement. These
                                           classes may also receive payments of
                                           interest.

Support Class (or companion class) ....    A class that receives principal
                                           payments on any payment date only if
                                           scheduled payments have been made on
                                           specified planned principal classes,
                                           targeted principal classes and/or
                                           scheduled principal classes.

 Targeted Principal Class .............    A class that is designated to receive
                                           principal payments using a
                                           predetermined principal balance
                                           schedule derived by assuming a single
                                           constant prepayment rate for the
                                           trust assets.

                                 INTEREST TYPES

Accrual ...............................    A class that adds accrued interest
                                           otherwise distributable on the class
                                           to the principal balance of the class
                                           on each applicable payment date. The
                                           accretion may continue until some
                                           specified event has occurred or until
                                           the class is retired.

Fixed Rate ............................    A class with a pass-through rate or

Floating Rate .........................    A class with an interest rate that
                                           resets periodically based upon a
                                           designated index and that varies
                                           directly with changes in that index.

Inverse Floating Rate .................    A class with an interest rate that
                                           resets periodically based upon a

Interest Only or IO ...................    A class that receives some or all of
                                           the interest payments made on the
                                           trust assets and little or no
                                           principal. Interest only certificates
                                           have either a nominal principal
                                           balance or a notional amount. A
                                           nominal principal balance represents
                                           actual principal that will be paid on
                                           the class. It is referred to as
                                           nominal since it is extremely small
                                           compared to other classes. A notional
                                           amount is an amount used as a
                                           reference to calculate the amount of
                                           interest due on an interest only
                                           security but is never actually paid
                                           out as principal on the class.

Partial Accrual .......................    A class that adds a portion of the
                                           amount of accrued interest thereon to
                                           the principal balance of the class on
                                           each applicable payment date, with
                                           the remainder of the accrued interest
                                           to be distributed currently as
                                           interest on the class on each
                                           applicable payment date. The
                                           accretion of designated amounts of
                                           the interest may continue until a
                                           specified event has occurred or until
                                           the class is retired.

Principal Only or PO ..................    A class that does not bear interest
                                           and is entitled to receive only
                                           distributions in respect of
                                           principal.

Variable Rate .........................    A class with a pass-through rate of
                                           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 loans in the
                                           trust).


BOOK-ENTRY REGISTRATION OF SECURITIES

      As described in the prospectus supplement, if not issued in fully
registered form, each class of securities will be registered as book-entry
securities. Persons acquiring beneficial ownership interests in the securities,
or "beneficial owners," will hold their securities through DTC in the United
States, or Clear stream Banking, societe anonyme (formerly Cedelbank), commonly
known as Clearstream, Luxembourg, or the Euroclear system, in Europe.
Clearstream, Luxembourg and Euroclear will hold omnibus positions for
Clearstream, Luxembourg participants and Euroclear participants, respectively,
through customers' securities accounts in Clearstream, Luxembourg's and
Euroclear's names on the books of their respective depositaries. The
depositaries will hold these positions in customers' collection accounts in the
depositaries names on DTC's books. The prospectus supplement will state if the
securities will be in physical rather than book-entry form.

                                      42


      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 Uniform Commercial Code and a clearing
agency registered under Section 17A of the Securities Exchange Act. DTC was
created to hold securities for its participants and facilitate the clearance and
settlement of securities transactions between its participants through
electronic book-entry changes in their accounts, eliminating the need for
physical movement of certificates. DTC's participants include securities brokers
and dealers, banks, trust companies and clearing corporations and may include
other organizations. Indirect access to the DTC system also is available to
indirect participants such as brokers, dealers, banks and trust companies that
clear through or maintain a custodial relationship with a DTC participant,
either directly or indirectly.

      Transfers between DTC participants will occur according to DTC rules.
Transfers between Clearstream, Luxembourg participants and Euroclear
participants will occur according to their applicable 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,
Luxembourg participants or Euroclear participants, on the other, will be
effected in DTC according to DTC rules on behalf of the relevant European
international clearing system by its depositary; however, those cross-market
transactions will require the counterparty to deliver instructions to the
relevant European international clearing system according to the counterparty
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 its depositary to take
action to effect final settlement on its behalf by delivering or receiving
securities in DTC, and making or receiving payment according to normal
procedures for same-day funds settlement applicable to DTC. Clearstream,
Luxembourg participants and Euroclear participants may not deliver instructions
directly to the depositaries.

      Because of time-zone differences, credits of securities in Clearstream,
Luxembourg or Euroclear resulting from a transaction with a DTC participant will
be made during the subsequent securities settlement processing, dated the
business day following the DTC settlement date, and the credits or any
transactions in the securities settled during the processing will be reported to
the relevant Clearstream, Luxembourg participant or Euroclear participant on
that business day. Cash received in Clearstream, Luxembourg or Euroclear
resulting from sales or securities by or through a Clearstream, Luxembourg
participant or a Euroclear participant to a DTC participant will be received
with value on the DTC settlement date but will be available in the relevant
Clearstream, Luxembourg or Euroclear cash account only as of the business day
following settlement in DTC.

      Clearstream, Luxembourg was incorporated in 1970 as Cedel S.A., a company
with limited liability under Luxembourg law (a societe anonyme). Cedel S.A.
subsequently e changed its name to Cedelbank. On January 10, 2000, Cedelbank's
parent company, Cedel International, societe anonyme, merged its clearing,
settlement and custody business with that of Deutsche Borse Clearing AG.

                                       43


      Clearstream, Luxembourg holds securities for its customers and facilitates
the clearance and settlement of securities transactions between Clearstream,
Luxembourg customers through electronic book-entry changes in accounts of
Clearstream, Luxembourg customers, thereby eliminating the need for physical
movement of certificates. Transactions may be settled by Clearstream, Luxembourg
in any of 36 currencies, including U.S. dollars. Clearstream, Luxembourg
provides, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. Clearstream, Luxembourg also deals with domestic
securities markets in over 30 countries through established depository and
custodial relationships. Clearstream, Luxembourg is registered as a bank in
Luxembourg, and as such is subject to regulation by the Commission de
Surveillance du Secteur Financier which supervises Luxembourg banks.
Clearstream, Luxembourg's customers are world-wide financial institutions
including underwriters, securities brokers and dealers, banks, trust companies
and clearing corporations. Clearstream, Luxembourg's U.S. customers are limited
to securities brokers and dealers, and banks. Currently, Clearstream, Luxembourg
has approximately 2,000 customers located in over 80 countries, including all
major European countries, Canada, and the United States. Indirect access to
Clearstream, Luxembourg is available to other institutions that clear through or
maintain a custodial relationship with an account holder of Clearstream,
Luxembourg. Clearstream, Luxembourg has established an electronic bridge with
Morgan Guaranty Trust Company of New York as the operator of the Euroclear
System in Brussels to facilitate settlement of trades between Clearstream,
Luxembourg and Euroclear."

      Euroclear was created in 1968 to hold securities for participants of
Euroclear and to clear and settle transactions between Euroclear participants
through simultaneous electronic book-entry delivery against payment, thereby
eliminating both the need for physical movement of securities and any risk from
lack of simultaneous transfers of securities and cash. Transactions may now be
settled in any of 37 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 Morgan Guaranty Trust Company of New
York, under contract with Euroclear Clearance Systems S.C., a Belgian
cooperative corporation. All operations are conducted by the Euroclear operator,
and all Euroclear securities clearance accounts and Euroclear cash accounts are
accounts with the Euroclear operator, not Euroclear Clearance. Euroclear
Clearance 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

                                       44


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 securities 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.

      Under a book-entry format, securityholders that are not DTC participants
or indirect participants but desire to purchase, sell or otherwise transfer
ownership of securities registered in the name of Cede, as nominee of DTC, may
do so only through participants and indirect participants. In addition, these
securityholders will receive all distributions of principal of and interest on
the securities from the trustee through DTC and its participants.
Securityholders may receive payments after the payment date because DTC will
forward these payments to its participants, which thereafter will be required to
forward these payments to indirect participants or securityholders. Unless and
until physical securities are issued, it is anticipated that the only security
holder will be Cede, as nominee of DTC, and that the beneficial holders of
securities will not be recognized by the trustee as securityholders under the
Agreements. Securityholders which are not DTC participants will only be
permitted to exercise their rights under the Agreements through DTC or through
its participants.

      Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers among its
participants and is required to receive and transmit payments of principal of
and interest on the securities. DTC's participants and indirect participants are
required to make book-entry transfers and receive and transmit payments on
behalf of their respective securityholders. Accordingly, although
securityholders will not possess physical securities, the rules provide a
mechanism by which securityholders will receive distributions and will be able
to transfer their interests.

      Unless and until physical securities are issued, securityholders who are
not DTC participants may transfer ownership of securities only through DTC
participants by instructing those participants to transfer securities, through
DTC for the account of the purchasers of the securities, which account is
maintained with their respective participants. Under DTC's rules and in
accordance with DTC's normal procedures, transfers of ownership of securities
will be executed through DTC and the accounts of the respective participants at
DTC will be debited and credited. Similarly, the respective participants will
make debits or credits, as the case may be, on their records on behalf of the
selling and purchasing securityholders.

      Because DTC can only act on behalf of its participants, who in turn act on
behalf of indirect participants and some banks, the ability of a securityholder
to pledge securities

                                       45


to persons or entities that do not participate in the DTC system, or otherwise
take actions in respect of the securities may be limited due to the lack of a
physical certificate for the securities.

      DTC advises that it will take any action permitted to be taken by a
security holder under the Agreements only at the direction of one or more of its
participants to whose account the securities are credited. Additionally, DTC
advises that it will take actions only at the direction of and on behalf of its
participants whose holdings include current principal amounts of outstanding
securities that satisfy the minimum percentage established in the Agreements.
DTC may take conflicting actions if directed by its participants.

      Any securities initially registered in the name of Cede, as nominee of
DTC, will be issued in fully registered, certificated form to securityholders or
their nominees, rather than to DTC or its nominee only under the events
specified in the Agreements and described in the prospectus supplement. Upon the
occurrence of any of the events specified in this prospectus or in the
Agreements and the prospectus supplement, DTC will be required to notify its
participants of the availability through DTC of physical certificates. Upon
surrender by DTC of the securities and receipt of instruction for
reregistration, the trustee will issue the securities in the form of physical
certificates, and thereafter the trustee will recognize the holders of the
physical certificates as securityholders. Thereafter, payments of principal of
and interest on the securities will be made by the trustee directly to
securityholders in accordance with the procedures set forth in the Agreements.
The final distribution of any security whether physical certificates or
securities registered in the name of Cede, however, will be made only upon
presentation and surrender of the securities on the final payment date at the
office or agency specified in the notice of final payment to securityholders.

      None of the depositor, the servicer, any Finance subsidiary, or the
trustee will have any liability for any actions taken by DTC or its nominee or
Cedel or Euroclear, including, without limitation, actions for any aspect of the
records relating to or payments made on account of the securities held by Cede,
as nominee for DTC, or for maintaining, supervising or reviewing any records
relating to the securities.

                               CREDIT ENHANCEMENT

GENERAL

      Credit enhancement may be provided with respect to one or more classes of
a series of securities or with respect to the related trust assets. Credit
enhancement may be in the form of:

      -     the subordination of one or more classes of the securities of such
            series;

      -     a limited financial guaranty policy issued by an entity named in the
            prospectus supplement;

      -     the establishment of one or more reserve accounts;

                                       46


      -     the use of a cross-collateralization feature;

      -     use of a mortgage pool insurance policy;

      -     excess spread,

      -     over-collateralization;

      -     letter of credit;

      -     guaranteed investment contract;

      -     primary mortgage insurance,

      -     other pledged assets,

      -     corporate guarantees,

      -     surety bond;

      -     special hazard insurance policy;

      -     bankruptcy bond;

      -     FHA insurance or V A guarantee;

      -     another method of credit enhancement contemplated in this prospectus
            and described in the prospectus supplement; and

      -     any combination of the foregoing.

      Unless otherwise specified in the prospectus supplement, credit
enhancement will not provide protection against all risks of loss and will not
guarantee repayment of the entire principal balance of the securities and
interest on the securities. If losses occur which exceed the amount covered by
credit enhancement or which are not covered by the credit enhancement,
securityholders will bear their allocable share of any deficiencies.

      If specified in the prospectus supplement, the coverage provided by one or
more of the forms of credit enhancement described in this prospectus may apply
concurrently to two or more separate trusts. If applicable, the prospectus
supplement will identify the trusts to which such credit enhancement relates and
the manner of determining the amount of coverage provided to those trusts by the
credit enhancement and of the application of that coverage to the related
trusts.

SUBORDINATION

      If specified in the prospectus supplement, protection afforded to holders
of one or more classes of securities of a series may be made by means of a
subordination feature. This protection may be accomplished by providing a
preferential right to holders of senior securities in a series to receive
distributions in respect of scheduled principal, principal prepayments, interest
or any combination thereof that otherwise would have been payable to holders of
subordinate securities in that series, under the circumstances and to the extent
specified in the prospectus supplement. Subordination protection may also be
afforded to the holders of senior securities by reducing the ownership interest
(if

                                       47


applicable) of the related subordinate securities, which protection may or may
not be in conjunction with the protection described in the immediately preceding
sentence. Finally, protection may be afforded to the holders of senior
securities by application of a subordination feature in another manner as
described in the prospectus supplement.

      If a subordination feature is present with respect to a given series,
delays in receipt of scheduled payments on the loans and losses on defaulted
loans may be borne First by the various classes of subordinate securities and
only thereafter by the various classes of senior securities, in each case under
the circumstances and subject to the limitations specified in the prospectus
supplement. The aggregate distributions in respect of delinquent payments on the
loans over the lives of the securities or at any time, the aggregate losses in
respect of defaulted loans which must be borne by the subordinate securities by
virtue of subordination and the amount of the distributions otherwise
distributable to the subordinate securityholders that will be distributable to
senior securityholders on any payment date all may be limited as specified in
the prospectus supplement. If aggregate distributions in respect of delinquent
payments on the loans or aggregate losses in respect of the related loans were
to exceed the amount specified in the prospectus supplement, then holders of
senior securities would experience losses.

      As specified in the prospectus supplement, all or any portion of
distributions otherwise payable to holders of subordinate securities on any
payment date may instead be deposited into one or more reserve accounts
established with the trustee or distributed to holders of senior securities. The
prospectus supplement will describe whether deposits are made into a reserve
account on each payment date, only during specified periods, only until the
balance in the related reserve account has reached a specified amount, only to
replenish amounts in the related reserve account following payments from the
reserve account to holders of senior securities or otherwise. Amounts on deposit
in a reserve account may be released to the holders of certain classes of
securities at the times and under the circumstances specified in the prospectus
supplement.

      If specified in the prospectus supplement, various classes of senior
securities and subordinate securities may themselves be subordinate in their
right to receive certain distributions to other classes of senior and
subordinate securities, respectively, through a cross-collateralization
mechanism or otherwise. As between classes of senior securities and as between
classes of subordinate securities, distributions may be allocated among the
classes:

      -     in the order of their scheduled final payment dates;

      -     in accordance with a schedule or formula;

      -     in relation to the occurrence of events; or

      -     otherwise, as specified in the prospectus supplement.

      As between classes of subordinate securities, payments to holders of
senior securities on account of delinquencies or losses and payments to any
reserve account will be allocated as specified in the prospectus supplement.

                                       48


INSURANCE POLICIES, SURETY BONDS, AND GUARANTIES

      If provided in the prospectus supplement, deficiencies in amounts
otherwise payable on the securities or certain classes of securities will be
covered by insurance policies and/or surety bonds provided by one or more
insurance companies or sureties. These instruments may cover, with respect to
one or more classes of securities, timely distributions of interest and/or full
distributions of principal on the basis of a schedule of principal distributions
set forth in or determined in the manner specified in the prospectus supplement.
In addition, if specified in the prospectus supplement, a trust may also include
a bankruptcy bond, a special hazard insurance policy, a demand note or other
insurance or guaranties for the purpose of:

      -     maintaining timely payments or providing additional protection
            against losses on the assets included in such trust;

      -     paying administrative expenses; or

      -     establishing a minimum reinvestment rate on the payments made in
            respect of those assets or principal payment rate on those assets.

      These arrangements may include agreements under which securityholders are
entitled to receive amounts deposited in various accounts held by the trustee
upon the terms specified in the prospectus supplement. A copy of any of these
types of instruments for a series will be Filed with the SEC as an exhibit to a
Current Report on Form 8-K to be Filed with the Commission within 15 days of
issuance of the securities.

CROSS SUPPORT

      If specified in the prospectus supplement, separate groups of assets
included in a trust may be evidenced by or secure only specified classes of the
related series of securities. If this is the case, credit support may be
provided by a cross support feature. This cross support feature would require
that cashflow received with respect to a particular group of assets First be
distributed as payments on the class of securities specifically related to those
assets, but after the necessary payments with respect to that class were made,
remaining cashflow from those assets would be available to make payments on one
or more other classes issued by the same trust. The prospectus supplement for a
series of securities which includes a cross support feature will describe the
manner and conditions for applying this cross support feature.

RESERVE ACCOUNTS

      If specified in the prospectus supplement, credit support with respect to
a series of securities will be provided by the establishment and maintenance
with the related trustee, in trust, of one or more reserve accounts for the
series. The prospectus supplement will specify whether or not any reserve
accounts so established will be included in the trust for such series.

                                       49


      Amounts deposited in the reserve account for a series will be specified in
the prospectus supplement and may include:

      -     cash, United States Treasury securities, instruments evidencing
            ownership of principal or interest payments thereon, letters of
            credit, demand notes, certificates of deposit or a combination of
            the foregoing in an aggregate amount specified in the prospectus
            supplement; or

      -     amounts generated by the trust assets deposited from time to time to
            which the subordinate securityholders, if any, would otherwise be
            entitled.

      Any amounts on deposit in the reserve account and the proceeds of any
other instrument deposited therein upon maturity will be held in cash or will be
invested in investments consisting of United States government securities and
other high-quality investments (""permitted investments"). Any instrument
deposited in a reserve account will name the trustee, in its capacity as trustee
for securityholders, or such other entity as is specified in the prospectus
supplement, as beneficiary and will be issued by an entity acceptable to each
rating agency that rates the securities. Additional information with respect to
instruments deposited in the reserve accounts will be set forth in the
prospectus supplement.

      Any amounts on deposit in the reserve accounts and payments on instruments
deposited therein will be available for withdrawal from the reserve account for
distribution to the holders of securities of the related series for the
purposes, in the manner and at the times specified in the prospectus supplement.

POOL INSURANCE POLICIES

      If specified in the prospectus supplement, a separate pool insurance
policy will be obtained for the pool and issued by the credit enhancer named in
the prospectus supplement. Each pool insurance policy will, subject to the
limitations described below, cover loss by reason of default in payment on loans
in the pool in an amount equal to a percentage specified in the prospectus
supplement of the aggregate principal balance of those loans on the cut-off
date. As more fully described below, the servicer will present claims under the
pool insurance policy to the credit enhancer on behalf of itself, the trustee
and the holders of the securities of the related series. The pool insurance
policies, however, are not blanket policies against loss, since claims
thereunder may only be made respecting particular defaulted loans and only upon
satisfaction of certain conditions precedent described below. The pool insurance
policies generally will not cover losses due to a failure to pay or denial of a
claim under a primary mortgage insurance policy.

      The pool insurance policies generally will provide that no claims may be
validly presented unless:

      -     any required primary mortgage insurance policy is in effect for the
            defaulted loan and a claim thereunder has been submitted and
            settled;

      -     hazard insurance on the related property has been kept in force and
            real estate taxes and other protection and preservation expenses
            have been paid;

                                       50


      -     if there has been physical loss or damage to the property, it has
            been restored to its physical condition (reasonable wear and tear
            excepted) at the time of issuance of the policy; and

      -     the insured has acquired good-and merchantable title to the property
            free and clear of liens except certain permitted encumbrances.

      Upon satisfaction of these conditions, the credit enhancer will have the
option either:

      -     to purchase the property securing the defaulted loan at a price
            equal to the principal balance thereof plus accrued and unpaid
            interest at the loan rate to the date of such purchase and certain
            expenses incurred by the servicer on behalf of the trustee and
            securityholders, net of certain amounts paid or assumed to have been
            paid under the related primary mortgage insurance policy; or

      -     to pay the amount by which the sum of the principal balance of the
            defaulted loan plus accrued and unpaid interest at the loan rate to
            the date of payment of the claim and the aforementioned expenses
            exceeds the proceeds received from an approved sale of the property,
            net of certain amounts paid or assumed to have been paid under the
            related primary mortgage insurance policy.

      If any property securing a defaulted loan is damaged and proceeds, if any,
from the related hazard insurance policy or the applicable special hazard
insurance policy are insufficient to restore the damaged property to a condition
sufficient to permit recovery under the pool insurance policy, the servicer will
not be required to expend its own funds to restore the damaged property unless
it determines that (a) such a restoration will increase the proceeds to
securityholders on liquidation of the loan after reimbursement of the servicer
for its expenses and (b) those expenses it incurs will be recoverable by it
through proceeds of the sale of the property or proceeds of the related pool
insurance policy or any related primary mortgage insurance policy.

      Like many primary insurance policies, the pool insurance policies may not
insure against loss sustained by reason of default arising from, among other
things:

      -     fraud or negligence in the origination or servicing of a loan,
            including misrepresentation by the borrower, the originator or
            persons involved in the origination of the loan;

      -     failure to construct a property in accordance with plans and
            specifications or

      -     losses arising from special hazards, such as earthquakes, floods,
            mudslides or vandalism.

A failure of coverage attributable to one of these events might result in a
breach of the related seller's representations regarding the loan and might give
rise to an obligation on the part of the seller to repurchase the defaulted loan
if it is unable to cure the breach. Many primary mortgage policies do not cover,
and no pool insurance policy will cover, a claim in respect of a defaulted loan
if the servicer of the loan was not approved by the applicable insurer either at
the time of default or thereafter.

                                       51


      The amount of coverage available under each pool insurance policy
generally will be reduced over the life of the related securities by the
positive difference, if any, between the aggregate dollar amount of claims paid
under the pool insurance policy minus the aggregate of the net amounts realized
by the credit enhancer upon disposition of the related foreclosed properties.
The amount of claims paid will include certain expenses incurred by the servicer
as well as accrued interest on delinquent loans to the date of payment of the
claim or another date set forth in the prospectus supplement. Accordingly, if
aggregate net claims paid under any pool insurance policy reach the original
policy limit, coverage under that pool insurance policy will be exhausted and
any further losses will be borne by the related securityholders.

OVER-COLLATERALIZATION

      Over-collateralization exists when the principal balance of the loans
supporting a class or classes of securities exceeds the principal balance of the
class or classes of securities themselves. If provided for in the prospectus
supplement, a portion of the interest payment received on the loans during a due
period may be paid to the securityholders on the related payment date as an
additional distribution of principal on a certain class or classes of
securities. This payment of interest as principal would accelerate the rate of
payment of principal on the class or classes of securities relative to the
principal balance of the loans in the related trust and thereby create or
increase over-collateralization.

LETTER OF CREDIT

      The letter of credit, if any, with respect to a series of securities will
be issued by the bank or financial institution specified in the prospectus
supplement. Under the letter of credit, the issuing bank will be obligated to
honor drawings thereunder in an aggregate Fixed dollar amount, net of
unreimbursed payments thereunder, equal to the percentage specified in the
prospectus supplement of the aggregate principal balance of the loans on the
related cut-off date or of one or more classes of securities. If specified in
the prospectus supplement, the letter of credit may permit drawings in the event
of losses not covered by insurance policies or other credit support, such as
losses arising from damage not covered by standard hazard insurance policies,
losses resulting from the bankruptcy of a borrower and the application of
certain provisions of the federal Bankruptcy Code, or losses resulting from
denial of insurance coverage due to misrepresentations in connection with the
origination of a loan. The amount available under the letter of credit will, in
all cases, be reduced to the extent of the unreimbursed payments thereunder. The
obligations of the issuing Bank under the letter of credit for each series of
securities will expire at the earlier of the date specified in the prospectus
supplement or the termination of the trust. A copy of the letter of credit for a
series, if any, will be Filed with the SEC as an exhibit to a Current Report on
Form 8-K to be Filed within 15 days of issuance of the securities of the related
series.

                                       52


OTHER INSURANCE, GUARANTIES, LETTERS OF CREDIT, AND SIMILAR INSTRUMENTS OR
AGREEMENTS

      If specified in the prospectus supplement, a trust may also include
insurance, guaranties, letters of credit or similar arrangements for the purpose
of:

      -     maintaining timely payments or providing additional protection
            against losses on the assets included in the trust;

      -     paying administrative expenses; or

      -     establishing a minimum reinvestment rate on the payments made in
            respect of those assets or principal payment rate on those assets.

      These arrangements may include agreements under which securityholders are
entitled to receive amounts deposited in various accounts held by the trustee
upon the terms specified in the prospectus supplement.

                       YIELD AND PREPAYMENT CONSIDERATIONS

      The yields to maturity and weighted average lives of the securities will
be affected primarily by the amount and timing of principal payments received on
or in respect of the trust assets. The original terms to maturity of the loans
in a given pool will vary depending upon the type of loans included therein.
Each prospectus supplement will contain information with respect to the type and
maturities of the loans in the related pool. The prospectus supplement will
specify the circumstances, if any, under which the related loans will be subject
to prepayment penalties. The prepayment experience on the loans in a pool will
affect the weighted average life of the securities.

      The rate of prepayments with respect to conventional mortgage loans has
fluctuated significantly in recent years. In general, if prevailing rates fall
significantly below the loan rates borne by the loans, such loans are more
likely to be subject to higher prepayment rates than if prevailing interest
rates remain at or above such loan rates. Conversely, if prevailing interest
rates rise appreciably above the loan rates borne by the loans, such loans are
more likely to experience a lower prepayment rate than if prevailing rates
remain at or below such loan rates. However, there can be no assurance that such
will be the case.

      The rate of prepayment on the loans cannot be predicted. Home equity loans
have been originated in significant volume only during the past few years and
the depositor is not aware of any publicly available studies or statistics on
the rate of prepayment of such loans. Generally, home equity loans are not
viewed by borrowers as permanent Financing. Accordingly, such loans may
experience a higher rate of prepayment than traditional First mortgage loans. On
the other hand, because home equity loans such as the revolving credit line
loans generally are not fully amortizing, the absence of voluntary borrower
prepayments could cause rates of principal payments lower than, or similar to,
those of

                                       53


traditional fully-amortizing first mortgage loans. The prepayment experience of
the trust may be affected by a wide variety of factors, including:

      -     general economic conditions;

      -     prevailing interest rate levels;

      -     availability of alternative financing;

      -     homeowner mobility;

      -     for junior liens, the amounts of, and interest rates on, the
            underlying senior mortgage loans; and

      -     the use of first mortgage loans as long-term financing for home
            purchase and subordinate mortgage loans as shorter-term financing
            for a variety of purposes, including home improvement, education
            expenses and purchases of consumer durables such as automobiles.

      In addition, any future limitations on the right of borrowers to deduct
interest payments on home equity loans for federal income tax purposes may
further increase the rate of prepayments of the loans.

      The yield to an investor who purchases securities in the secondary market
at a price other than par will vary from the anticipated yield if the rate of
prepayment on the loans is actually different than the rate anticipated by the
investor at the time the securities were purchased.

      Collections on home equity loans may vary because, among other things,
borrowers may:

      -     make payments during any month as low as the minimum monthly payment
            for that month or, during the interest-only period for certain
            revolving credit line loans and, in more limited circumstances,
            closed-end loans, with respect to which an interest-only payment
            option has been selected, the interest and the fees and charges for
            such month;

      -     make payments as high as the entire outstanding principal balance
            plus accrued interest and the fees and charges thereon;

      -     fail to make the required periodic payments; or

      -     vary payments month to month due to seasonal purchasing and other
            personal payment habits.

      When a full prepayment is made on a loan, the borrower is charged interest
on the principal amount of the prepaid loan not for the entire month in which
the prepayment is made, but only for the number of days in the month actually
elapsed up to the date of the prepayment. The effect of prepayments in full will
be to reduce the amount of interest passed through or paid in the following
month to securityholders because interest on the principal amount of any prepaid
loan will generally be paid only to the date of prepayment. Partial prepayments
in a given month may be applied to the outstanding principal balances of the
prepaid loans on the first day of the month of receipt or the

                                       54


month following receipt. In the latter case, partial prepayments will not reduce
the amount of interest passed through or paid in the month in which the partial
prepayment was made. Generally, neither full nor partial prepayments will be
passed through or paid to securityholders until the month following receipt.

      Even assuming that the properties provide adequate security for the loans,
substantial delays could be encountered in connection with the liquidation of
defaulted loans, which would give rise to corresponding delays in the receipt by
securityholders of the proceeds of a liquidation. An action to foreclose on a
property securing a loan is regulated by state statutes and rules and is subject
to many of the delays and expenses of other lawsuits if defenses or
counterclaims are interposed, sometimes requiring several years to complete.
Furthermore, in some states an action to obtain a deficiency judgment is not
permitted following a nonjudicial sale of a property. In the event of a default
by a borrower, these restrictions among other things, may impede the ability of
the servicer to foreclose on or sell the property or to obtain liquidation
proceeds sufficient to repay all amounts due on the related loan. In addition,
the servicer will be entitled to deduct from related liquidation proceeds all
expenses reasonably incurred in attempting to recover amounts due and not yet
repaid on defaulted loans, including payments to senior lien holders, legal fees
and costs of legal action, real estate taxes and maintenance and preservation
expenses.

      Liquidation expenses with respect to defaulted mortgage loans generally do
not vary directly with the outstanding principal balance of the mortgage loan
being liquidated. Therefore, assuming that a servicer took the same steps in
realizing upon a defaulted mortgage loan having a small outstanding principal
balance as it would in the case of a defaulted mortgage loan having a large
outstanding principal balance, the amount realized after expenses of liquidation
would be smaller as a percentage of the outstanding principal balance for the
former mortgage loan as opposed to the latter.

      If the rate at which interest is passed through or paid to the holders of
securities of a series is calculated on a loan-by-loan basis, disproportionate
principal prepayments among loans with different loan rates will affect the
yield on such securities. In most cases, the effective yield to securityholders
will be lower than the yield otherwise produced by the applicable pass-through
rate or interest rate and purchase price, because while interest will accrue on
each loan from the first day of the month (unless otherwise specified in the
prospectus supplement), the distribution of such interest will not be made
earlier than the month following the month of accrual.

      Under certain circumstances, the servicer, the depositor, the holders of
the residual interests in a REMIC or any person specified in the prospectus
supplement may be obligated to or may have the option to purchase either the
assets of a trust or some or all of the securities and thereby effect earlier
retirement or redemption of the related series of securities.

      The relative contribution of the various factors affecting prepayment may
vary from time to time. There can be no assurance as to the rate of payment of
principal of the trust assets at any time or over the lives of the securities.

                                       55


      The prospectus supplement will discuss in greater detail the effect of the
rate and timing of principal payments (including prepayments), delinquencies and
losses on the yield, weighted average lives and maturities of the securities.

                                 THE AGREEMENTS

      Set forth below is a description of the material provisions of the
Agreements which are not described elsewhere in this prospectus. The description
is subject to, and qualified in its entirety by reference to, the provisions of
each Agreement. Where particular provisions or terms used in the Agreements are
referred to, such provisions or terms are as specified in the Agreements. As
specified in the related prospectus supplement, certain of the rights of
securityholders described below may be exercised by the credit enhancer for the
related series of securities without the consent of the securityholders and
certain rights of securityholders may not be exercised without the written
consent of the credit enhancer.

ASSIGNMENT OF THE TRUST ASSETS

      ASSIGNMENT OF THE LOANS. At the time of issuance of the securities, the
depositor will cause the loans to be assigned or pledged to the trustee for the
benefit of the securityholders, without recourse, together with all principal
and interest received by or on behalf of the depositor on or with respect to
such loans after the cut-off date, other than principal and interest due on or
before the cut-off date and other than any amounts specified in the prospectus
supplement. Concurrently with this sale, the trustee will deliver the securities
to the depositor in exchange for the loans. Each loan will be identified in a
schedule appearing as an exhibit to the related Agreement. Such schedule will
include information as to the outstanding principal balance of each loan after
application of payments due on or before the cut-off date, as well as
information regarding the loan rate or annual percentage rate, the maturity of
the loan, the loan-to-value ratios, combined loan-to-value ratios or effective
loan-to-value ratios, as applicable, at origination and certain other
information.

      Unless otherwise specified in the prospectus supplement, the related
Agreement will require that, within the time period specified therein, the
depositor will also deliver or cause to be delivered to the trustee or, if so
indicated in the prospectus supplement, a separate custodian appointed by the
trustee pursuant to a custodial agreement, as to each mortgage loan or home
equity loan, among other things:

      -     the mortgage note or credit line agreement endorsed without recourse
            in blank or to the order of the trustee;

      -     the mortgage, deed of trust or similar instrument with evidence of
            recording indicated thereon, except that in the case of any mortgage
            not returned form the public recording office, the depositor will
            deliver or cause to be delivered a copy of such mortgage together
            with a certificate that the original of the mortgage was delivered
            to such recording office;

                                       56


      -     an assignment of the mortgage to the trustee, which assignment will
            be in recordable form in the case of a mortgage assignment; and

      -     all other security documents, including those relating to any senior
            interests in the property, that are specified in the prospectus
            supplement or the related Agreement.

      If specified in the prospectus supplement, the depositor will promptly
cause the assignments of the loans to be recorded in the appropriate public
office for real property records. If specified in the prospectus supplement,
some or all of the loan documents may not be delivered to the trustee until
after the occurrence of certain events specified in the prospectus supplement.

      In lieu of delivering the mortgage or deed of trust and an assignment of
the mortgage to the trustee, for any loans registered on the MERS(R) System the
depositor will cause the trustee to be recorded as the beneficial owner of the
loans pursuant to the MERS rules for electronically tracking changes in
ownership rights.

      The trustee or the appointed custodian will review the loan documents
within the time period specified in the prospectus supplement after receipt
thereof to ascertain that all required documents have been properly executed and
received, and the trustee will hold the loan documents in trust for the benefit
of the related securityholders. Unless otherwise specified in the prospectus
supplement, if any loan document is found to be missing or defective in any
material respect, the trustee or the custodian, as appropriate, will notify the
servicer and the depositor, and the servicer will notify the related seller. If
the related seller cannot cure the omission or defect within the time period
specified in the prospectus supplement after receipt of notice from the
servicer, the seller will be obligated to either purchase the related loan from
the trust at the purchase price or, if so specified in the prospectus
supplement, remove such loan from the trust and substitute in its place one or
more other loans that meets certain requirements as set forth in the prospectus
supplement. There can be no assurance that a seller will fill this purchase or
substitution obligation. Unless otherwise specified in the prospectus
supplement, this obligation to cure, purchase or substitute constitutes the sole
remedy available to the securityholders or the trustee for omission of, or a
material defect in, a loan document.

      Notwithstanding the foregoing provisions, with respect to a trust for
which a REMIC election is to be made, no purchase or substitution of a loan will
be made if the purchase or substitution would result in a prohibited transaction
tax under the Code.

      NO RECOURSE TO SELLERS; DEPOSITOR OR SERVICER. As described above under
"--Assignment of the Loans," the depositor will cause the loans comprising the
trust to be assigned or pledged to the trustee, without recourse. However, each
seller will be obligated to repurchase or substitute for any loan as to which
certain representations and warranties are breached or for failure to deliver
certain documents relating to the loans as described in this prospectus under
"Assignment of the Loans" and "Loan Program -- Representations by Sellers;
Repurchases." These obligations to purchase or substitute constitute the sole
remedy available to the securityholders or the trustee for a breach of any such
representation or warranty or failure to deliver a constituent document.

                                       57


PAYMENTS ON LOANS; DEPOSITS TO COLLECTION ACCOUNT

      The servicer will establish and maintain or cause to be established and
maintained with respect to the each trust a separate account or accounts for the
collection of payments on the trust assets in the trust (the "collection
account"). The prospectus supplement may provide for other requirements for the
collection account, but if it does not, then the collection account must be
either:

      -     maintained with a depository institution the short-term debt
            obligations of which (or, in the case of a depository institution
            that is the principal subsidiary of a holding company, the
            short-term debt obligations of such holding company) are rated in
            one of the two highest short-term rating categories by the rating
            agency that rated one or more classes of the related series of
            securities;

      -     an account or accounts the deposits in which are fully insured by
            the FDIC;

      -     an account or accounts the deposits in which are insured by the FDIC
            to the limits established by the FDIC and the uninsured deposits in
            which are otherwise secured such that, as evidenced by an opinion of
            counsel, securityholders have a claim with respect to the funds in
            such account or accounts, or a perfected first-priority security
            interest against any collateral securing those funds, that is
            superior to the claims of any other depositors or general creditors
            of the depository institution with which such account or accounts
            are maintained; or

      -     an account or accounts otherwise acceptable to the rating agency.

      The collateral eligible to secure amounts in the collection account is
limited to permitted investments. A collection account may be maintained as an
interest bearing account or the funds held therein may be invested pending each
succeeding payment date in Permitted Investments. The servicer, the trustee or
any other entity described in the prospectus supplement may be entitled to
receive interest or other income earned on funds in the collection account as
additional compensation and will be obligated to deposit in the collection
account the amount of any loss when realized. The collection account may be
maintained with the servicer or with a depository institution that is an
affiliate of the servicer, provided it meets the standards set forth above.

      The servicer or trustee will deposit or cause to be deposited in the
collection account for each trust, to the extent applicable and unless otherwise
specified in the prospectus supplement and provided in the related Agreement,
the following payments and collections received or advances made by or on behalf
of it subsequent to the cut-off date (other than certain payments due on or
before the cut-off date and any excluded amounts):

      -     all payments on account of principal and interest (which may be net
            of the applicable servicing compensation), including principal
            prepayments and, if specified in the prospectus supplement, any
            applicable prepayment penalties, on the loans;

      -     all net insurance proceeds, less any incurred and unreimbursed
            advances made by the servicer, of the hazard insurance policies and
            any primary mortgage insurance policies, to the extent such proceeds
            are not applied to the restoration of the

                                       58


            property or released to the mortgagor in accordance with the
            servicer's normal servicing procedures;

      -     all proceeds received in connection with the liquidation of
            defaulted loans, less any expenses of liquidation and any
            unreimbursed advances made by the servicer with respect to the
            liquidated loans;

      -     any net proceeds received on a monthly basis with respect to any
            properties acquired on behalf of the securityholders by foreclosure
            or deed in lieu of foreclosure;

      -     all advances as described in this prospectus under "Description of
            the Securities -- Advances ";

      -     all proceeds of any loan or property in respect thereof repurchased
            by any seller as described under "Loan Program -- Representations by
            Sellers; Repurchases" or "-- Assignment of Trust Assets" above and
            all proceeds of any loan repurchased as described under "--
            Termination; Optional Termination" below;

      -     all payments required to be deposited in the collection account with
            respect to any deductible clause in any blanket insurance policy
            described under "-- Hazard Insurance" below;

      -     any amount required to be deposited by the servicer in connection
            with losses realized on investments for the benefit of the servicer
            of funds held in the collection account and, to the extent specified
            in the prospectus supplement, any payments required to be made by
            the servicer in connection with prepayment interest shortfalls; and

      -     all other amounts required to be deposited in the collection account
            pursuant to the related agreement.

      The servicer or the depositor, as applicable, may from time to time direct
the institution that maintains the collection account to withdraw funds from the
collection account for the following purposes:

      -     to transfer funds for the trustee for distribution of payments due
            on the securities and other purposes set forth in the prospectus
            supplement;

      -     to pay to the servicer the purchase price of any additional balances
            transferred to the trustee resulting from draws under revolving
            lines of credit as set forth in the prospectus supplement;

      -     to pay to the servicer the servicing fees described in the
            prospectus supplement and, as additional servicing compensation,
            earnings on or investment income with respect to funds in the
            collection account credited thereto;

      -     to reimburse the servicer for advances made with respect to a loan,
            but only from amounts received that represent late payments of
            principal on, late payments of interest on, insurance proceeds
            received with respect to or liquidation proceeds received with
            respect to the same loan;

      -     to reimburse the servicer for any advances previously made which the
            servicer has determined to be nonrecoverable;

                                       59


      -     to reimburse the servicer from insurance proceeds for expenses
            incurred by the servicer and covered by insurance policies;

      -     to reimburse the servicer for unpaid servicing fees and unreimbursed
            out-of-pocket costs and expenses incurred by the servicer in the
            performance of its servicing obligations, such right of
            reimbursement being limited to amounts received representing late
            recoveries of the payments for which the original advances were
            made;

      -     to pay to the servicer, with respect to each loan or property
            acquired in respect thereof that has been purchased by the servicer
            pursuant to the Agreement, all amounts received thereon and not
            taken into account in determining the principal balance of that
            repurchased loan,

      -     to reimburse the servicer or the depositor for expenses incurred and
            reimbursable pursuant to the Agreement;

      -     to pay or reimburse the trustee or any other party as provided in
            the prospectus supplement;

      -     to withdraw any amount deposited in the collection account that was
            not required to be deposited therein; and

      -     to clear and terminate the collection account upon termination of
            the Agreement.

      In addition, unless otherwise specified in the prospectus supplement, on
or prior to the business day immediately preceding each payment date, the
servicer shall withdraw from the collection account the amount of available
funds, to the extent on deposit, for deposit in an account maintained by the
trustee.

      The applicable Agreement may require the servicer to establish and
maintain one or more escrow accounts into which mortgagors deposit amounts
sufficient to pay taxes, assessments, hazard insurance premiums or comparable
items. Withdrawals from the escrow accounts maintained for mortgagors may be
made to effect timely payment of taxes, assessments and hazard insurance
premiums or comparable items, to reimburse the servicer out of related
assessments for maintaining hazard insurance, to refund to mortgagors amounts
determined to be overages, to remit to mortgagors, if required, interest earned,
if any, on balances in any of the escrow accounts, to repair or otherwise
protect the property and to clear and terminate any of the escrow accounts. The
servicer will be solely responsible for administration of the escrow accounts
and will be expected to make advances to such accounts when a deficiency exists
therein.

PRE-FUNDING ACCOUNT

      If provided in the prospectus supplement, the servicer will establish and
maintain, in the name of the trustee on behalf of the securityholders, a
pre-funding account into which the depositor will deposit cash or other assets
on the closing date. The pre-funding account will be maintained with the
trustee. The deposit will not exceed 50% of the initial aggregate principal
amount of the securities.

      The cash on deposit in the pre-funding account will be used by the trustee
to purchase additional loans for the trust from the depositor from time to time
during the funding period. Monies on deposit in the prefunding account will not
be available to

                                       60


cover losses on or in respect of the loans. The funding period for a trust will
begin on the closing date and will end on the date specified in the prospectus
supplement, which will not be later than one year after the closing date. Monies
on deposit in the pre-funding account may be invested in permitted investments
as specified in the related Agreement. Earnings on investment of funds in the
pre-funding account will be applied as specified in the prospectus supplement
and losses will be charged against the funds on deposit in the pre-funding
account. Any amounts remaining the pre-funding account at the end of the funding
period will be distributed to securityholders as a prepayment of principal, in
the manner and priority specified in the prospectus supplement.

      In addition, if provided in the prospectus supplement, on the related
closing date the depositor will make a deposit to a capitalized interest
account, which will be maintained by the trustee. The funds on deposit in the
capitalized interest account will be used solely to cover shortfalls in interest
that may arise as a result of utilization of the pre-funding account. Monies on
deposit in the capitalized interest account will not be available to cover
losses on or in respect of the loans. To the extent that the entire amount on
deposit in the capitalized interest account has not been used to cover
shortfalls in interest by the end of the funding period, any remaining amounts
will be paid to the depositor.

SUBSERVICING BY SELLERS

      The servicer may enter into subservicing agreements with any servicing
entity which will act as the subservicer for the loans, which subservicing
agreements will not contain any terms inconsistent with the related Agreement.
While each subservicing agreement will be a contract solely between the
servicer and the subservicer, the Agreement pursuant to which a series of
securities is issued will provide that, if for any reason the servicer for that
series of securities is no longer the servicer of the loans, the trustee or any
successor servicer must recognize the subscriber's rights and obligations under
the related sub servicing agreement. Notwithstanding any subservicing
arrangement, unless otherwise provided in the prospectus supplement, the
servicer will remain liable for its servicing duties and obligations under the
servicing agreement as if the servicer alone were servicing the loans.

COLLECTION PROCEDURES

      The servicer, directly or through one or more subservicers, will make
reasonable efforts to collect all payments called for under the loans and will,
consistent with each Agreement and any pool insurance policy, primary mortgage
insurance policy, FHA insurance, VA guaranty, bankruptcy bond or alternative
arrangements, follow those collection procedures that are customary with respect
to loans that are comparable to the loans. Consistent with the above, the
servicer may, in its discretion:

      -     waive any prepayment charge, assumption fee, late payment or other
            charge in connection with a loan; and

      -     to the extent not inconsistent with the rules applicable to REMIC,
            and with the coverage of an individual loan by a pool insurance
            policy, primary mortgage insurance policy, FHA insurance, VA
            guaranty, bankruptcy bond or alternative arrangements, if
            applicable, suspend or reduce regular monthly payment on the

                                       61


            loan for a period of up to six months, or arrange with the related
            borrower a schedule for the liquidation of delinquencies.

The servicer's obligation, if any, to make or cause to be made advances on a
loan will remain during any period of this type of arrangement.

      Under the Agreement, the servicer will be required to enforce due-on-sale
clauses with respect to any loans to the extent contemplated by the terms of
those loans and permitted by applicable law. Where an assumption of, or
substitution of liability with respect to, a loan is required by law, upon
receipt of assurance that the primary mortgage insurance policy covering such
loan will not be affected, the servicer may permit the assumption of a loan,
pursuant to which the original borrower would remain liable on the related loan
note, or a substitution of liability with respect to the loan, pursuant to which
the new borrower would be substituted for the original borrower as being liable
on the loan note. Any fees collected for entering into an assumption or
substitution of liability agreement may be retained by the servicer as
additional servicing compensation. In connection with any assumption or
substitution, generally neither the loan rate borne by the related loan note nor
its payment terms may be changed.

HAZARD INSURANCE

      Except as otherwise specified in the prospectus supplement, the servicer
will require the mortgagor or obligor on each loan to maintain a hazard
insurance policy providing coverage against loss by fire and other hazards which
are covered under the standard extended coverage endorsement customary for the
type of property in the state in which such property is located. This hazard
insurance coverage will be in an amount that is at least equal to the lesser of:

      -     the maximum insurable value of the improvements securing the loan
            from time to time; and

      -     either the combined principal balance owing on the loan and any
            mortgage loan senior to such loan or an amount such that the
            proceeds of the policy shall be sufficient to prevent the mortgagor
            or obligor and/or the lender from becoming a co-insurer, whichever
            is greater.

All amounts collected by the servicer under any hazard policy (except for
amounts to be applied to the restoration or repair of the property or released
to the mortgagor or obligor in accordance with the servicer's normal servicing
procedures) will be deposited in the related collection account. In the event
that the servicer maintains a blanket policy insuring against hazard losses on
all the loans comprising part of a trust, it will conclusively be deemed to have
satisfied its obligation relating to the maintenance of hazard insurance. If the
blanket policy relating to a trust contains a deductible clause, the servicer
will be required to deposit from its own funds into the collection account an
amount equal to the amount which would have been deposited therein but for the
deductible clause.

                                       62


      In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements securing a loan by fire,
lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions listed in each policy.
Although the policies relating to the loans may have been underwritten by
different insurers under different state laws in accordance with different
applicable forms and therefore may not contain identical terms and conditions,
the basic terms of these types of policies are dictated by respective state
laws, and most hazard policies typically do not cover (among other things) any
physical damage resulting from the following:

      -     war;

      -     revolution;

      -     governmental actions;

      -     floods and other water-related causes;

      -     earth movement, including earthquakes, landslides and mud flows;

      -     nuclear reactions;

      -     wet or dry rot;

      -     vermin, rodents, insects or domestic animals; or

      -     theft and, in certain cases, vandalism.

The foregoing list is merely indicative of certain kinds of uninsured risks and
is not intended to be all inclusive.

      If, however, any mortgaged property at the time of origination of the
related loan is located in an area identified by the Flood Emergency Management
Agency as having special flood hazards and flood insurance has been made
available, the servicer will cause to be maintained with a generally acceptable
insurance carrier a flood insurance policy in accordance with mortgage servicing
industry practice. Any flood insurance policy so maintained will provide
coverage in an amount at least equal to the lesser of the principal balance of
the loan and the minimum amount required under the terms of coverage to
compensate for any damage or loss on a replacement cost basis. The amount of
coverage provided will not be greater than the maximum amount of flood insurance
available for the related mortgaged property under either the regular or
emergency programs of the National Flood Insurance Program.

      The hazard insurance policies covering properties securing the loans
typically contain a 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 insured property in order to recover the full amount of
any partial loss. If the insured's coverage falls below this specified
percentage, then the insurer's liability in the event of partial loss will not
exceed the larger of (a) the replacement costs of the improvements less physical
depreciation and (b) such proportion of the loss 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 the servicer may cause to be
maintained on the

                                       63


improvements securing a loan declines as the principal balances owing on the
loan itself decrease, and since improved real estate generally has appreciated
in value over time in the past, the effect of this requirement in the event of
partial loss may be that hazard insurance proceeds will be insufficient to
restore fully the damaged property.

PRIMARY MORTGAGE INSURANCE

      The servicer will maintain or cause to be maintained, as the case may be
and as permitted by law, in full force and effect, to the extent specified in
the prospectus supplement, a primary mortgage insurance policy with regard to
each loan for which that coverage is required. Unless required by law, the
servicer will not cancel or refuse to renew any primary mortgage 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 Agreement unless the
replacement primary mortgage insurance policy for the cancelled or nonrenewed
policy is maintained with an insurer whose claims-paying ability is sufficient
to maintain the current rating of the classes of securities of that series that
have been rated.

      Although the terms and conditions of primary mortgage insurance vary, the
amount of a claim for benefits under a primary mortgage insurance policy
covering a mortgage loan will consist of the insured percentage of the unpaid
principal amount of the covered loan and accrued and unpaid interest on the loan
and reimbursement of certain expenses, less:

      -     all rents or other payments collected or received by the insured
            (other than the proceeds of hazard insurance) that are derived from
            or in any way related to the property;

      -     hazard insurance proceeds in excess of the amount required to
            restore the property and which have not been applied to the payment
            of the loan;

      -     amounts expended but not approved by the insurer of the related
            primary mortgage insurance policy;

      -     claim payments previously made by the insurer; and

      -     unpaid premiums.

      Primary mortgage insurance policies reimburse certain losses sustained by
reason of default in payments by borrowers. Primary mortgage insurance policies
will not insure against, and exclude from coverage, losses sustained by reason
of a default arising from or involving certain matters, including:

      -     fraud or negligence in origination or servicing of the loans,
            including misrepresentation by the originator, mortgagor (or
            obligor) or other persons involved in the origination of the loan;

      -     failure to construct the property subject to the loan in accordance
            with specified plans;

                                       64


      -     physical damage to the property; and

      -     the related subservicer not being approved as a servicer by the
            insurer.

      Evidence of each primary mortgage insurance policy will be provided to the
trustee simultaneously with the transfer to the trustee of the loan. The
servicer, on behalf of itself, the trustee and the securityholders, is required
to present claims to the insurer under any primary mortgage insurance policy and
to take reasonable steps that are necessary to permit recovery thereunder with
respect to defaulted loans. Amounts collected by the servicer on behalf of the
servicer, the trustee and the securityholders shall be deposited in the related
collection account for distribution as set forth above.

CLAIMS UNDER INSURANCE POLICIES AND OTHER REALIZATION UPON DEFAULTED LOANS

      The servicer or subservicers, on behalf of the trustee and
securityholders, will present claims to the insurer under any applicable
insurance policies. If the property securing a defaulted loan is damaged and
proceeds, if any, from the related hazard insurance policy are insufficient to
restore the damaged property, the servicer is not required to expend its own
funds to restore the damaged property unless it determines (a) that such
restoration will increase the proceeds to securityholders on liquidation of the
loan after reimbursement of the servicer for its expenses and (b) that the
expenditure will be recoverable by it from related insurance proceeds or
liquidation proceeds.

      If recovery on a defaulted loan under any insurance policy is not
available, or if the defaulted loan is not covered by an insurance policy, the
servicer will be obligated to follow or cause to be followed those normal
practices and procedures that it deems necessary or advisable to realize upon
the defaulted loan. If the net proceeds after reimbursable expenses of any
liquidation of the property securing the defaulted loan are less than the
principal balance of the loan plus interest accrued thereon that is payable to
securityholders, the trust will realize a loss in the amount of that difference
plus the aggregate of expenses incurred by the servicer in connection with the
liquidation proceedings and which are reimbursable under the Agreement.

      The proceeds from any liquidation of a loan will be applied in the
following order of priority:

      -     First, to reimburse the servicer for any unreimbursed expenses
            incurred by it to restore the related property and any unreimbursed
            servicing compensation payable to the servicer with respect to the
            loan;

      -     second, to reimburse the servicer for any unreimbursed advances with
            respect to the loan;

      -     third, to accrued and unpaid interest (to the extent no advance has
            been made for that amount) on the loan; and

      -     fourth, as a recovery of principal of the loan.

                                       65


SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

      The servicer's primary compensation for its activities as servicer will
come from the payment to it, with respect to each interest payment on a loan, of
the amount specified in the prospectus supplement. As principal payments are
made on the loans, the portion of each monthly payment which represents interest
will decline, and thus servicing compensation to the servicer will decrease as
the loans amortize. Prepayments and liquidations of loans prior to maturity will
also cause servicing compensation to the servicer to decrease. Subservicers, if
any, will be entitled to a monthly servicing fee as described in the prospectus
supplement in compensation for their servicing duties. In addition, the servicer
or subservicer will retain all prepayment charges, assumption fees and late
payment charges, to the extent collected from borrowers, and any benefit that
may accrue as a result of the investment of funds in the applicable collection
account (unless otherwise specified in the prospectus supplement).

      The servicer will pay or cause to be paid certain ongoing expenses
associated with each trust and incurred by it in connection with its
responsibilities under the related Agreement, including, without limitation, and
only if specified in the prospectus supplement, payment of any fee or other
amount payable in respect of any credit enhancement arrangements, the trustee,
any custodian appointed by the trustee, the certificate registrar and any paying
agent, and payment of expenses incurred in enforcing the obligations of
subservicers and sellers. The servicer will be entitled to reimbursement of
expenses incurred in enforcing the obligations of subservicers and sellers under
certain limited circumstances.

EVIDENCE AS TO COMPLIANCE

      Each Agreement will provide that the servicer at its expense shall cause a
firm of independent public accountants to furnish a report annually to the
trustee. Each annual report will state that the firm has performed certain
procedures specified in the related Agreement and that the review has disclosed
no items of noncompliance with the provisions of the Agreement which, in the
opinion of the firm, are material, except for any items of noncompliance that
are forth in such report.

      Each Agreement will also provide for delivery to the trustee, on or before
a specified date in each year, of an annual statement signed by an officer of
the servicer to the effect that the servicer has fulfilled its obligations under
the Agreement throughout the preceding year.

CERTAIN MATTERS REGARDING THE SERVICER AND THE DEPOSITOR

      The servicer under each pooling and servicing agreement or servicing
agreement, as applicable, will be named in the prospectus supplement. The entity
serving as servicer may have normal business relationships with the depositor or
the depositor's affiliates.

      Each Agreement will provide that the servicer may not resign from its
obligations and duties under the Agreement except upon (a) appointment of a
successor servicer and receipt by the trustee of a letter from the applicable
rating agency or rating agencies that the servicer's resignation and the
successor servicer's appointment will not result in

                                       66


a downgrade of the securities or (b) a determination that its performance of its
duties thereunder is no longer permissible under applicable law. The servicer
may, however, be removed from its obligations and duties as set forth in the
Agreement. No resignation by the servicer will become effective until the
trustee or a successor servicer has assumed the servicer's obligations and
duties under the Agreement.

      Each Agreement generally will further provide that neither the servicer,
the depositor nor any director, officer, employee, or agent of the servicer or
the depositor (each, an ""indemnified party") will be under any liability to the
related trust or securityholders for taking any action or for refraining from
taking any action in good faith pursuant to the Agreement, or for errors in
judgment; provided, however, that neither the servicer, the depositor nor any
such person will be protected against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. Each Agreement generally will further provide
that each indemnified party will be entitled to indemnification by the related
trust and will be held harmless against any loss, liability or expense incurred
in connection with any legal action relating to the Agreement or the securities
for the related series, other than any loss, liability or expense related to any
specific loan or loans (except any loss, liability or expense otherwise
reimbursable pursuant to the Agreement) and any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or gross negligence in the
performance of that indemnified party's duties thereunder or by reason of
reckless disregard by that indemnified party of obligations and duties
thereunder. In addition, each Agreement generally will provide that neither the
servicer nor the depositor will be under any obligation to appear in, prosecute
or defend any legal action which is not incidental to its respective
responsibilities under the Agreement and which in its opinion may involve it in
any expense or liability. The servicer or the depositor may, however, in its
discretion undertake any action which it may deem necessary or desirable with
respect to the Agreement and the rights and duties of the parties thereto and
the interests of the securityholders thereunder. In that event, the legal
expenses and costs of the action and any liability resulting therefrom will be
expenses, costs and liabilities of the trust, and the servicer or the depositor,
as the case may be, will be entitled to be reimbursed for those costs and
liabilities out of funds which would otherwise be distributed to
securityholders.

      Except as otherwise specified in the prospectus supplement, any person
into which the servicer may be merged or consolidated, or any person resulting
from any merger or consolidation to which the servicer is a party, or any person
succeeding to the business of the servicer, will be the successor of the
servicer under each Agreement, provided that that person is qualified to sell
mortgage loans to, and service mortgage loans on behalf of, Fannie Mae or
Freddie Mac. Furthermore, the merger, consolidation or succession may not
adversely Affect the then current rating or ratings of the class or classes of
securities of the related series that have been rated.

                                       67


EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT

      POOLING AND SERVICING AGREEMENT; SERVICING AGREEMENT. Events of default
under each Agreement will be specified in the prospectus supplement and may
include:

      -     any failure by the servicer to make an Advance which continues
            unremedied for one business day;

      -     any failure by the servicer to make or cause to be made any other
            required payment pursuant to the Agreement which continues
            unremedied for one business day after written notice of such failure
            to the servicer in the manner specified in the Agreement;

      -     any failure by the servicer duly to observe or perform in any
            material respect any of its other covenants or agreements in the
            Agreement which continues unremedied for sixty days after written
            notice of the failure to the servicer in the manner specified in the
            Agreement; and

      -     certain events of insolvency, readjustment of debt, marshalling of
            assets and liabilities or similar proceedings and certain actions by
            or on behalf of the servicer indicating its insolvency,
            reorganization or inability to pay its obligations.

      Unless otherwise provided in the prospectus supplement, so long as an
event of default under an Agreement remains unremedied, the trustee may, and at
the direction of holders of securities evidencing not less than 25% of the
aggregate voting rights of such series and under such other circumstances as may
be specified in such Agreement, the trustee shall terminate all of the rights
and obligations of the servicer under the Agreement relating to such trust and
in and to the related trust assets, whereupon the trustee will succeed to all of
the responsibilities, duties and liabilities of the servicer under the
Agreement, including, if specified in the prospectus supplement, the obligation
to make advances, and will be entitled to similar compensation arrangements. In
the event that the trustee is unwilling or unable to act as successor to the
servicer, it may appoint, or petition a court of competent jurisdiction for the
appointment of, a housing and home finance institution which is a Fannie Mae or
Freddie Mac approved servicer with a net worth of a least $15,000,000 to act as
successor to the servicer under the Agreement. Pending the appointment of a
successor servicer, the trustee is obligated to act in such capacity. The
trustee and any such successor may agree upon the servicing compensation to be
paid, which in no event may be greater than the compensation payable to the
servicer under the Agreement.

      Unless otherwise provided in the prospectus supplement, no securityholder,
solely by virtue of the securityholder's status as a securityholder, will have
any right under any Agreement to institute any proceeding with respect to that
Agreement, unless the securityholder previously has given to the trustee written
notice of default and unless the holders of securities evidencing not less than
25% of the aggregate voting rights for the related series have made written
request upon the trustee to institute such proceeding in its own name as trustee
thereunder and have offered to the trustee reasonable indemnity, the trustee for
60 days has neglected or refused to institute any such proceeding, and all other
conditions precedent for the initiation of suit as described in the Agreement
have

                                       68


been met. However, the trustee is under no obligation to exercise any of the
trusts or powers vested in it by the Agreement for any series or to make any
investigation of matters arising thereunder or to institute, conduct or defend
any litigation thereunder or in relation thereto at the request, order or
direction of any securityholders, unless those securityholders have offered and
provided to the trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby.

      INDENTURE. Except as otherwise specified in the prospectus supplement,
events of default or rapid amortization events under the indenture for each
series of notes or bonds include:

      -     a default in the payment of any principal of or interest on any note
            or bond as specified in the prospectus supplement;

      -     failure to perform in any material respect any other covenant of the
            depositor or the trust in the indenture which continues for a period
            of thirty (30) days after notice thereof is given in accordance with
            the procedures described in the prospectus supplement;

      -     certain events of bankruptcy, insolvency, receivership or
            liquidation of the depositor or the trust; or

      -     any other event of default provided with respect to notes or bonds
            of that series including, but not limited to, certain defaults on
            the part of the trust, if any, of a credit enhancement instrument
            supporting such notes or bonds.

      If an event of default with respect to the notes or bonds of any series at
the time outstanding occurs and is continuing, either the trustee or the holders
of a majority of the then aggregate outstanding amount of the notes or bonds of
that series or the credit enhancer of that series, if any, may declare the
principal amount (or, if the notes or bonds have an interest rate of 0%, that
portion of the principal amount as may be specified in the terms of that series,
as provided in the prospectus supplement) of all the notes or bonds of that
series to be due and payable immediately. This declaration may, under certain
circumstances, be rescinded and annulled by the holders of more than 50% of the
aggregate voting rights of the bonds of the related series. Rapid amortization
events will trigger an accelerated rate of payment of principal on the notes or
bonds, as described in the related prospectus supplement.

      If, following an event of default with respect to any series of notes or
bonds, the notes or bonds of that series have been declared to be due and
payable and the prospectus supplement and applicable Agreement so provide, the
trustee may, in its discretion, notwithstanding the acceleration of the notes or
bonds, elect to maintain possession of the collateral securing the notes or
bonds of that series and to continue to apply distributions 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 or bonds of that series as they would have become due if there had not
been such a declaration. In addition, unless otherwise specified in the
prospectus supplement, the trustee may not sell or otherwise liquidate the
collateral securing the

                                       69


notes or bonds of a series following an event of default or a rapid amortization
event, unless:

      -     the holders of 100% of the aggregate voting rights of the bonds of
            such series consent to the sale;

      -     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 or bonds of the series at the date of the sale; or

      -     the trustee determines that the collateral would not be sufficient
            on an ongoing basis to make all payments on the notes or bonds as
            those payments would have become due if the notes or bonds had not
            been declared due and payable, and the trustee obtains the consent
            of the holders of 66 2/3% of the aggregate voting rights of the
            notes or bonds of that series.

      In the event that the trustee liquidates the collateral in connection with
an event of default or a rapid amortization event, the indenture provides that
the trustee will have a prior lien on the proceeds of that liquidation for
unpaid fees and expenses. As a result, upon the occurrence of an event of
default or rapid amortization event, the amount available for distribution to
the noteholders or bondholders could 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 or bondholders after the
occurrence of an event of default or rapid amortization event.

      Except as otherwise specified in the prospectus supplement, in the event
the principal of the notes or bonds of a series is declared due and payable, as
described above, the holders of any of the notes or bonds 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 which is unamortized.

      Subject to the provisions of the indenture relating to the duties of the
trustee, in case an event of default or a rapid amortization event shall occur
and be continuing with respect to a series of notes or bonds, the trustee shall
be under no obligation to exercise any of the rights or powers under the
indenture at the request or direction of any of the holders of notes or bonds of
the series, unless those holders offer to the trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which might be
incurred by it in complying with their request or direction. Subject to these
provisions for indemnification and certain limitations contained in the
indenture, the holders of a majority of the then aggregate outstanding amount of
the notes or bonds of a series shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the trustee
or exercising any trust or power conferred on the trustee with respect to the
notes or bonds of the series, and the holders of a majority of the then
aggregate outstanding amount of the notes or bonds of the series may, in certain
cases, waive any default with respect thereto, except a default in the payment
of principal or interest or a default in respect of a covenant or provision of
the indenture that cannot be modified without the waiver or consent of all the
holders of the outstanding notes or bonds of the series affected thereby.

                                       70


AMENDMENT

      Except as otherwise specified in the prospectus supplement, each Agreement
may be amended by the depositor, the servicer, the trustee and, if applicable,
the credit enhancer, without the consent of any of the securityholders:

      -     to cure any ambiguity;

      -     to correct a defective provision or correct or supplement any
            provision therein which may be inconsistent with any other provision
            therein;

      -     to make any other revisions with respect to matters or questions
            arising under the Agreement which are not inconsistent with the
            provisions thereof; or

      -     to comply with any requirements imposed by the Code or any
            regulation thereunder; provided, however, that no such amendments
            (except those pursuant to this clause) will adversely affect in any
            material respect the interests of any security holder.

      An amendment will be deemed not to adversely affect in any material
respect the interests of the securityholders if the trustee receives a letter
from each rating agency requested to rate the class or classes of securities of
such series stating that the proposed amendment will not result in the
downgrading or withdrawal of the respective ratings then assigned to the related
securities. Each Agreement may also be amended by the depositor, the servicer,
the trustee and, if applicable, the credit enhancer with consent of holders of
securities of such series evidencing not less than 66 2/3% of the aggregate
voting rights of each class affected thereby for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Agreement or of modifying in any manner the rights of the holders of the
related securities; provided, however, that no such amendment may (a) reduce in
any manner the amount of, or delay the timing of, payments received on loans
which are required to be distributed on any security without the consent of the
holder of such security, or (b) with respect to any series of securities, reduce
the aforesaid percentage of securities of any class the holders of which are
required to consent to any such amendment without the consent of the holders of
all securities of such class covered by such Agreement then outstanding. If a
REMIC election is made with respect to a trust, the trustee will not be entitled
to consent to an amendment to the related Agreement without having first
received an opinion of counsel to the effect that the proposed amendment will
not cause such trust to fail to qualify as a REMIC.

TERMINATION; OPTIONAL TERMINATION

      POOLING AND SERVICING AGREEMENT; TRUST AGREEMENT. Unless otherwise
specified in the related Agreement, the obligations created by each pooling and
servicing agreement and trust agreement for each series of securities will
terminate upon the payment to the

                                       71


related securityholders of all amounts held in the collection account or by the
servicer and required to be paid to them pursuant to the Agreement following the
later of:

      (a)   the final payment of or other liquidation of the last of the trust
            assets subject thereto or the disposition of all property acquired
            upon foreclosure of any such trust assets remaining in the trust;
            and

      (b)   the purchase by the servicer or, if REMIC treatment has been elected
            and if specified in the prospectus supplement, by the holder of the
            residual interest or any other party specified to have such rights
            (see ""Federal Income Tax Consequences" below), from the related
            trust of all of the remaining trust assets and all property acquired
            in respect of the related trust assets.

      Unless otherwise specified by the prospectus supplement, any purchase of
trust assets and property acquired in respect of trust assets evidenced by a
series of securities will be made at the option of the servicer, such other
person or, if applicable, the holder of the REMIC residual interest, at a price
specified in the prospectus supplement. The exercise of this right will effect
early retirement of the securities of that series, but the right of the
servicer, such other person or, if applicable, the holder of the REMIC residual
interest, to so purchase is subject to the principal balance of the related
trust assets being less than the percentage specified in the prospectus
supplement of the aggregate principal balance of the trust assets at the Cut-Off
Date for the series. The foregoing is subject to the provision that if a REMIC
election is made with respect to a trust, any repurchase pursuant to clause (b)
above will be made only in connection with a "qualified liquidation" of the
REMIC within the meaning of Section 860F(g)(4) of the Code.

      INDENTURE. The indenture will be discharged with respect to a series of
notes or bonds, except with respect to certain continuing rights specified in
the indenture, upon the delivery to the trustee for cancellation of all the
notes or bonds of the related series or, with certain limitations, upon deposit
with the trustee of funds sufficient for the payment in full of all of the notes
or bonds of that series.

      In addition to this type of discharge with certain limitations, the
indenture will provide that, if so specified with respect to the notes or bonds
of any series, the related trust will be discharged from any and all obligations
in respect of the notes or bonds of the related series (except for certain
obligations relating to temporary notes or bonds and exchange of notes or bonds,
to register the transfer of or exchange notes or bonds of such series, to
replace stolen, lost or mutilated notes or bonds of such series, to maintain
paying agencies and to hold monies for payment in trust) upon the deposit with
the trustee, in trust, of money and/or direct obligations of or obligations
guaranteed by the United States of America which through the payment of interest
and principal in respect thereof in accordance with their terms will provide
money in an amount sufficient to pay the principal of and each installment of
interest on the notes or bonds of the series on the last scheduled payment date
for the notes or bonds and any installment of interest on the notes or bonds in
accordance with the terms of the indenture and the notes or bonds of that
series. In the event of any defeasance and discharge of notes or bonds of the
series, holders of notes or bonds of the series would be able to look only to
that money

                                       72


and/or those direct obligations for payment of principal and interest, if any,
on their notes or bonds until maturity.

THE TRUSTEE

      The trustee under each Agreement will be named in the prospectus
supplement. The commercial bank, savings and loan association or trust company
serving as trustee may have banking and other relationships with the depositor,
the servicer and any of their respective affiliates.

                       CERTAIN LEGAL ASPECTS OF THE LOANS

      The following discussion contains summaries, which are general in nature,
of certain legal matters relating to the loans. Because these legal aspects are
governed primarily by applicable state law and because the applicable state laws
may differ substantially from state to state, the descriptions do not, except as
expressly provided below, reflect the laws of any particular state, nor do they
encompass the laws of all states in which the security for the loans is
situated. The descriptions are qualified in their entirety by reference to the
applicable federal laws and the appropriate laws of the states in which loans
may be originated.

GENERAL

      DEEDS OF TRUST AND MORTGAGES. The loans for a series may be secured by
deeds of trust, mortgages, security deeds or deeds to secure debt, depending
upon the prevailing practice in the state in which the property subject to the
loan is located. Deeds of trust are used almost exclusively in California
instead of mortgages. A mortgage creates a lien upon the real property
encumbered by the mortgage, which lien is generally not prior to the lien for
real estate taxes and assessments. Priority between mortgages depends on their
terms and generally on the order of recording with a state or county office.
There are two parties to a mortgage, the mortgagor, who is the borrower and
owner of the mortgaged property, and the mortgagee, who is the lender. Under the
mortgage instrument, the mortgagor delivers to the mortgagee a note or bond and
the mortgage. Although a deed of trust is similar to a mortgage, a deed of trust
formally has three parties, the borrower-property owner called the trustor
(similar to a mortgagor), a lender (similar to a mortgagee) called the
beneficiary, 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. A security deed and a deed to secure debt are special types of deeds
which indicate on their face that they are granted to secure an underlying debt.
By executing a security deed or deed to secure debt, the grantor conveys title
to, as opposed to merely creating a lien upon, the subject property to the
grantee until such time as the underlying debt is repaid. The trustee's
authority under a deed of trust, the mortgagee's authority under a mortgage and
the grantee's authority under a security deed or deed to secure debt are
governed by law and, with respect to some deeds of trust, the directions of the
beneficiary.

                                       73


      COOPERATIVE LOANS. Some of the loans may be cooperative loans. A
cooperative is owned by tenant-stockholders, who, through ownership of stock,
shares or membership certificates in the corporation, receive proprietary leases
or occupancy agreements which confer exclusive rights to occupy specific units.
The cooperative owns the real property and the specific units and is responsible
for management of the property. An ownership interest in a cooperative and the
accompanying rights are Financed through a cooperative share loan evidenced by a
promissory note and secured by a security interest in the occupancy agreement or
proprietary lease and in the related cooperative shares.

FORECLOSURE/REPOSSESSION

      DEED OF TRUST. Foreclosure of a deed of trust is generally accomplished by
a non-judicial sale under a specific provision in the deed of trust which
authorizes the trustee to sell the property at public auction upon any default
by the borrower under the terms of the note or deed of trust. In certain states,
these foreclosures also may be accomplished by judicial action in the manner
provided for foreclosure of mortgages. In addition to any notice requirements
contained in a deed of trust, in some states, including California, the trustee
must record a notice of default and send a copy to the borrower-trustor, to any
person who has recorded a request for a copy of any notice of default and notice
of sale, to any successor in interest to the borrower-trustor, to the
beneficiary of any junior deed of trust and to certain other persons. In some
states, including California, the borrower-trustor has the right to reinstate
the loan at any time following default until shortly before the trustee's sale.
In general, the borrower, or any other person having a junior encumbrance on the
real estate, may, during a statutorily prescribed reinstatement period, cure a
monetary default by paying the entire amount in arrears plus other designated
costs and expenses incurred in enforcing the obligation. Generally, state law
controls the amount of foreclosure expenses and costs, including attorney's
fees, which may be recovered by a lender. After the reinstatement period has
expired without the default having been cured, the borrower or junior lienholder
no longer has the right to reinstate the loan and must pay the loan in full to
prevent the scheduled foreclosure sale. If the deed of trust is not reinstated
within any applicable cure period, a notice of sale must be posted in a public
place and, in most states, including California, published for a specific period
of time in one or more newspapers. In addition, 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 California, the entire
process from recording a notice of default to a non-judicial sale usually takes
four to Five months.

      MORTGAGES. Foreclosure of a mortgage is generally accomplished by judicial
action. The action is initiated by the service of legal pleadings upon all
parties having an interest 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
parties. When the mortgagee's right to foreclosure is contested, the legal
proceedings necessary to resolve the issue can be time consuming. After the
completion of a judicial foreclosure proceeding, the court generally issues a
judgment of foreclosure and appoints a referee or other court officer to conduct
the sale of the

                                       74


property. In some states, mortgages may also be foreclosed by advertisement,
pursuant to a power of sale provided in the mortgage.

      Although foreclosure sales are typically public sales, frequently no third
party purchaser bids in excess of the lender's lien because of the difficulty of
determining the exact status of title to the property, the possible
deterioration of the property during the foreclosure proceedings and a
requirement that the purchaser pay for the property in cash or by cashier's
check. Thus the foreclosing lender often purchases the property from the trustee
or referee for an amount equal to the principal amount outstanding under the
loan, accrued and unpaid interest and the expenses of foreclosure in which event
the mortgagor's debt will be extinguished or the lender may purchase for a
lesser amount in order to preserve its right against a borrower to seek a
deficiency judgment in states where deficiency judgments are available.
Thereafter, subject to the right of the borrower in some states to remain in
possession during the redemption period, the lender will assume the burden of
ownership, including obtaining hazard insurance and making repairs at its own
expense as are necessary to render the property suitable for sale. The lender
will commonly 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. Any loss may be reduced by the receipt of
any mortgage guaranty insurance proceeds.

      Courts have imposed general equitable principles upon foreclosure, which
are generally designed to mitigate the legal consequences to the borrower of the
borrower's 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 of the borrower's
default and the likelihood that the borrower will be able to reinstate the loan.
In some cases, courts have eliminated the right of a lender to realize upon its
security if the default under the security agreement is not monetary, such as
the borrower's failure to maintain the property adequately or the borrower's
execution of secondary Financing affecting the property. Finally, some courts
have been faced with the issue of whether federal or state constitutional
provisions reflecting due process concerns for fair notice require that
borrowers under deeds of trust receive notice longer than that prescribed by
statue. 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
does not involve sufficient state action to afford constitutional protection to
the borrower.

      When the beneficiary under a junior mortgage or deed of trust cures the
default and reinstates or redeems by paying the full amount of the senior
mortgage or deed of trust, the amount paid by the beneficiary to cure or redeem
becomes a part of the indebtedness secured by the junior mortgage or deed of
trust.

      COOPERATIVE LOANS. The cooperative shares owned by the tenant-stockholder
and pledged to the lender are, in almost all cases, subject to restrictions on
transfer as set forth in the cooperative's certificate of incorporation and
bylaws, as well as the proprietary lease or occupancy agreement, and may be
cancelled by the cooperative for

                                       75


failure by the tenant-stockholder to pay rent or other obligations or charges
owed by such tenant-stockholder, including mechanics' liens against the
cooperative apartment building incurred by such tenant-stockholder. The
proprietary lease or occupancy agreement generally permits the cooperative to
terminate such lease or agreement in the event an obligor fails to make payments
or defaults in the performance of covenants required thereunder. Typically, the
lender and the cooperative enter into a recognition agreement which establishes
the 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 such lease or
agreement until the lender has been provided with 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 the sale of the cooperative apartment,
subject, however, to the cooperative's right to sums due under such 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 value of the collateral below the outstanding
principal balance of the cooperative loan and accrued and unpaid interest
thereon.

      Recognition agreements also provide that in the event of a foreclosure on
a cooperative loan, the lender must obtain the approval or consent of the
cooperative as required by the proprietary lease before transferring the
cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.

      In some states, foreclosure on the cooperative shares is accomplished by a
sale in accordance with the provisions of Article 9 of the Uniform Commercial
Code and the security agreement relating to those shares. Article 9 requires
that a sale be conducted in a "commercially reasonable" manner. Whether a
foreclosure 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 foreclosure. Generally, a sale conducted according to the
usual practice of banks selling similar collateral will be considered reasonably
conducted.

      Article 9 also 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 security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the cooperative 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

                                       76


responsible for the deficiency. Please refer to the discussion under the heading
"Anti-Deficiency Legislation; Bankruptcy Laws; Tax Liens" below.

      In the case of foreclosure on a building which was converted from a rental
building to a building owned by a cooperative under a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property subject
to rent control and rent stabilization laws which apply to certain tenants who
elected to remain in the building but who did not purchase shares in the
cooperative when the building was so converted.

ENVIRONMENTAL RISKS

      Real property pledged as security to a lender may be subject to
environmental risks. Such risks, among other things, could substantially impair
a borrower's ability to repay a loan, result in substantial diminution in the
value of the property pledged as collateral to secure the loan and/or give rise
to liability which could exceed the value of such property or the principal
balance of the related loan.

      Under the laws of certain states, contamination of a property may give
rise to a lien on the property to assure the payment of the costs of clean-up.
In several states this type of lien has priority over the lien of an existing
mortgage against the related property. In addition, under the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980
("CERCLA"), the United States Environmental Protection Agency ("EPA") may
impose a lien on property where the EPA has incurred clean-up costs. However, a
CERCLA lien is subordinate to pre-existing, perfected security interests.

      Under the laws of some states, and under CERCLA, it is conceivable that a
secured lender may be held liable as an owner or operator for the costs of
addressing releases or threatened releases of hazardous substances at a
mortgaged property and related costs, even though the environmental damage or
threat was caused by a prior or current owner or operator or another third
party. CERCLA imposes liability for these costs on any and all responsible
parties, including owners or operators. However, CERCLA excludes from the
definition of "owner or operator" a secured creditor who, without participating
in the management of a facility or property, holds indicia of ownership
primarily to protect its security interest (the "secured creditor exclusion").
Thus, if a lender's activities begin to encroach on the actual management of a
contaminated facility or property, the lender may incur liability as an owner or
operator under CERCLA. Similarly, if a lender forecloses and takes title to a
contaminated facility or property, the lender may incur CERCLA liability in
various circumstances, including, but not limited to, when it holds the facility
or property as an investment (including leasing the facility or property to a
third party), or fails to market the property in a timely fashion.

      If a lender is or becomes liable, it may be entitled to bring an action
for contribution against any other responsible parties, including a previous
owner or operator, who created the environmental hazard, but those persons or
entities may be bankrupt or otherwise judgment-proof. The costs associated with
environmental cleanup and the diminution in value of contaminated property and
related liabilities or losses may be

                                       77


substantial. It is conceivable that the costs arising from the circumstances set
forth above would result in a loss to securityholders.

      CERCLA does not apply to petroleum products, and the secured creditor
exclusion does not govern liability for cleanup costs under federal laws other
than CERCLA, in particular Subtitle I of the federal Resource Conservation and
Recovery Act ("RCRA"), which regulates underground petroleum storage tanks
(except heating oil tanks). The EPA has adopted a lender liability rule for
underground storage tanks under Subtitle I of RCRA. Under that rule, a holder of
a security interest in an underground storage tank or real property containing
an underground storage tank is not considered an operator of the underground
storage tank as long as the holder does not exercise decision making control
over the borrower's enterprise, participate in the management or control of
decision making relating to the operation of a tank, as long as petroleum is not
added to, stored in or dispensed from the tank, or as long as holder does not
deviate from certain other requirements specified in the rule. In addition,
under the Asset Conservation, Lender Liability and Deposit Insurance Protection
Act of 1996, similar protections to those accorded to lenders under CERCLA are
also accorded to holders of security interests in underground tanks. It should
be noted, however, that liability for cleanup of contamination may be governed
by state law, which may not provide for any specific protection for secured
creditors.

      Whether actions taken by a lender would constitute participation in the
management of a mortgaged property, or the business of a borrower, so as to
render the secured creditor exemption unavailable to a lender has been a matter
of judicial interpretation of the statutory language, and court decisions have
been inconsistent. In 1990, the Court of Appeals for the Eleventh Circuit
suggested that the mere capacity of the lender to influence a borrower's
decisions regarding disposal of hazardous substances was sufficient
participation in the management of the borrower's business to deny the
protection of the secured creditor exemption to the lender, regardless of
whether lender actually exercised such influence.

      This ambiguity appears to have been resolved by the enactment of the Asset
Conservation, Lender Liability and Deposit Insurance Protection Act of 1996. The
legislation provides that in order to be deemed to have participated in the
management of a mortgaged property, a lender must actually participate in the
operational affairs of the property or the borrower. The legislation also
provides that participation in the management of the property does not include
"merely having the capacity to influence, or unexercised right to control"
operations. Rather, a lender will lose the protection of the secured creditor
exclusion 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
secured property. As noted above, the secured creditor exclusion does not govern
liability for cleanup costs except under the federal laws discussed above. In
addition, certain other environmental conditions may be required to be addressed
under other federal, state or local laws or in order to improve the
marketability of a property. Therefore, under certain circumstances, including
but not limited to after foreclosure, a lender may incur costs under applicable
laws or in order to improve the marketability of a property in

                                       78


connection with environmental conditions associated with that property, such as
the presence or release of regulated materials in underground storage tanks,
asbestos-containing material, lead paint or radon gas. If a lender is or becomes
liable, it can bring an action for contribution against any other "responsible
parties" including a previous owner or operator, who created the environmental
hazard, but those persons or entities may be bankrupt or otherwise
judgment-proof. It is conceivable that the costs arising from such circumstances
would result in a loss to securityholders.

      Except as otherwise specified in the prospectus supplement, at the time
the loans were originated, no environmental assessments or very limited
environmental assessments of the properties were conducted.

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 from the foreclosure sale. In certain
other states, including California, this right of redemption applies only to
sales following judicial foreclosure, and not to sales pursuant to a
non-judicial power of sale. In most states where the right of redemption is
available, statutory redemption may occur upon payment of the foreclosure
purchase price, accrued interest and taxes. In other states, redemption may be
authorized 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. The exercise of a right of redemption
would defeat the title of any purchaser from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run. In some states, there
is no right to redeem property after a trustee's sale under a deed of trust.

ANTI-DEFICIENCY LEGISLATION; BANKRUPTCY LAWS; TAX LIENS

      Certain states have imposed statutory and judicial restrictions that limit
the remedies of a beneficiary under a deed of trust or a mortgagee under a
mortgage. In some states, including California, statutes and case law limit the
right of the beneficiary or mortgagee to obtain a deficiency judgment against
borrowers financing the purchase of their residence or following sale under a
deed of trust or certain other foreclosure proceedings. A deficiency judgment is
a personal judgment against the borrower equal in most cases to the difference
between the amount due to the lender and the fair market value of the real
property at the time of the foreclosure sale. As a result of these prohibitions,
it is anticipated that in most instances the servicer will utilize the
non-judicial foreclosure remedy and will not seek deficiency judgments against
defaulting borrowers.

      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 certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting that security;
however, in some of these states, the lender,

                                       79


following judgment on such personal action, may be deemed to have elected a
remedy and may be precluded from exercising remedies with respect to the
security. Consequently, the practical effect of the election requirement, when
applicable, is that lenders will usually proceed first against the security
rather than bringing a personal action against the borrower. In some states,
exceptions to the anti-deficiency statutes are provided for in certain instances
where the value of the lender's security has been impaired by acts or omissions
of the borrower, for example, in the event of waste of the property. Finally,
other statutory provisions limit any deficiency judgment against the former
borrower following a foreclosure sale to the excess of the outstanding debt over
the fair market value of the property at the time of the public sale. The
purpose of these statutes is generally to prevent a beneficiary or a mortgagee
from obtaining a large deficiency judgment against the former borrower as a
result of low or no bids at the foreclosure sale.

      In addition to anti-deficiency and related legislation, 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 its security. For
example, in a proceeding under the federal Bankruptcy Code, a lender may not
foreclose on a mortgaged property without the permission of the bankruptcy
court. The rehabilitation plan proposed by the debtor may provide, if the
mortgaged property is not the debtor's principal residence and the court
determines that the value of the mortgaged property is less than the principal
balance of the mortgage loan, for the reduction of the secured indebtedness to
the value of the mortgaged property as of the date of the commencement of the
bankruptcy, rendering the lender a general unsecured creditor for the
difference, and also may reduce the monthly payments due under such mortgage
loan, change the rate of interest and alter the mortgage loan repayment
schedule. The effect of any proceedings under the federal Bankruptcy Code,
including, but not limited to, any automatic stay, could result in delays in
receiving payments on the loans underlying a series of securities and possible
reductions in the aggregate amount of payments.

      The federal tax laws provide priority to certain tax liens over the lien
of a mortgage or secured party.

DUE-ON-SALE CLAUSES

      Each conventional loan generally will contain a due-on-sale clause which
will generally provide that if the mortgagor or obligor sells, transfers or
conveys the property, the loan or contract may be accelerated by the mortgagee
or secured party. Court decisions and legislative actions have placed
substantial restrictions on the right of lenders to enforce these clauses in
many states. For instance, the California Supreme Court in August 1978 held that
due-on-sale clauses were generally unenforceable. However, the Garn-St. Germain
Depository Institutions Act of 1982 (the "Garn-St. Germain Act"), subject to
certain exceptions, preempts state constitutional, statutory and case law
prohibiting the enforcement of due-on-sale clauses. As a result, due-on-sale
clauses are generally enforceable except in those states whose legislatures
exercised their authority to regulate the enforceability of the clauses with
respect to mortgage loans that

                                       80


were (a) originated or assumed during the "window period" under the Garn-St.
Germain Act which ended in all cases not later than October 15, 1982, and (b)
originated by lenders other than national banks, federal savings institutions
and federal credit unions. Freddie Mac has taken the position in its published
mortgage servicing standards that, out of a total of eleven "window period
states," Five states (Arizona, Michigan, Minnesota, New Mexico and Utah) have
enacted statutes extending, on various terms and for varying periods, the
prohibition on enforcement of due-on-sale clauses with respect to certain
categories of window period loans. Also, 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.

      As to loans secured by an owner-occupied residence, the Garn-St. Germain
Act sets forth nine specific instances in which a mortgagee covered by the
Garn-St. Germain Act may not exercise its rights under a due-on-sale clause,
notwithstanding the fact that a transfer of the property may have occurred. The
inability to enforce a due-on-sale clause may result in transfer of the related
property to an uncreditworthy person, which could increase the likelihood of
default or may result in a mortgage bearing an interest rate below the current
market rate being assumed by a new home buyer, which may Affect the average life
of the loans and the number of loans which may extend to maturity.

      In addition, under federal bankruptcy law, due-on-sale clauses may not be
enforceable in bankruptcy proceedings and may, under certain circumstances, be
eliminated in any modified mortgage resulting from such bankruptcy proceeding.

ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES

      Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Under certain state laws, prepayment charges may not be imposed
after a certain period of time following the origination of mortgage loans with
respect to prepayments on loans secured by liens encumbering owner-occupied
residential properties. The absence of such a restraint on prepayment,
particularly with respect to Fixed rate loans having higher loan rates, may
increase the likelihood of refinancing or other early retirement of the related
loans or contracts. Late charges and prepayment fees are typically retained by
servicers as additional servicing compensation.

APPLICABILITY OF USURY LAWS

      Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V") provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The Office of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized to
issue rules and regulations and to publish interpretations governing
implementation of Title V. Title V authorized the states to

                                       81


reimpose interest rate limits by adopting, before April 1, 1983, a law or
constitutional provision which expressly rejects application of the federal law.
Fifteen states adopted such a 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 mortgage
loans covered by Title V.

      Certain states have taken action to reimpose interest rate limits and/or
to limit discount points or other charges.

SERVICE MEMBERS CIVIL RELIEF ACT

      Generally, under the terms of the Service members Civil Relief Act
formerly known as the Soldiers' and Sailors' Relief Act of 1940, (the "Relief
Act"), a borrower who enters military service after the origination of his or
her loan (including a borrower who is a member of the National Guard or is in
reserve status at the time of the origination of the loan and is later called to
active duty) may not be charged interest above an annual rate of 6% during the
period of his or her active duty status, unless a court orders otherwise upon
application of the lender. It is possible that this interest rate limitation
could have an effect, for an indeterminate period of time, on the ability of the
servicer to collect full amounts of interest on certain of the loans. Unless
otherwise provided in the prospectus supplement, any shortfall in interest
collections resulting from the application of the Relief Act could result in
losses to securityholders. The Relief Act also imposes limitations which would
impair the ability of the servicer to foreclose on an affected loan during the
borrower's period of active duty status. Moreover, the Relief Act permits the
extension of a loan's maturity and the re-adjustment of its payment schedule
beyond the completion of military service. Thus, in the event that a loan that
is affected by the Relief Act goes into default, there may be delays and losses
occasioned by the inability to realize upon the property in a timely fashion.

JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGEES

      To the extent that the loans comprising the trust for a series are secured
by mortgages which are junior to other mortgages held by other lenders or
institutional investors, the rights of the trust (and therefore the
securityholders), as mortgagee under any such junior mortgage, are subordinate
to those of any mortgagee under any senior mortgage. The senior mortgagee has
the right to receive hazard insurance and condemnation proceeds and to cause the
property securing the loan to be sold upon default of the mortgagor, thereby
extinguishing the junior mortgagee's lien unless the junior mortgagee asserts
its subordinate interest in the property in foreclosure litigation and,
possibly, satisfies the defaulted senior mortgage. A junior mortgagee may
satisfy a defaulted senior loan in full and, in some states, may cure a default
and bring the senior loan current, in either event 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.

      The standard form of the mortgage 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

                                       82


those proceeds and awards to any indebtedness secured by the mortgage, in
whatever 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 a
senior mortgage 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 mortgage. Proceeds in excess of the amount of senior mortgage
indebtedness, in most cases, may be applied to the indebtedness of a junior
mortgage.

      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 appear 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 obligations, the mortgagee is
given the right under certain mortgages to perform the obligation itself, at its
election, with the mortgagor reimbursing the mortgagee for any sums expended by
the mortgagee on behalf of the mortgagor. All sums so expended by the mortgagee
become part of the indebtedness secured by the mortgage.

      The form of credit line trust deed or mortgage generally used by most
institutional lenders which make revolving credit line loans typically contains
a future advance clause, which provides, in essence, that additional amounts
advanced to or on behalf of the borrower by the beneficiary or lender are to be
secured by the deed of trust or mortgage. Any amounts so advanced after the
Cut-off Date with respect to any mortgage will be included in the trust. The
priority of the lien securing any advance made under a future advance clause may
depend in most states on whether the deed of trust or mortgage is called and
recorded as a credit line deed of trust or mortgage. If the beneficiary or
lender advances additional amounts, the advance is entitled to receive the same
priority as amounts initially advanced under the trust deed or mortgage,
notwithstanding the fact that there may be junior trust deeds or mortgages and
other liens which intervene between the date of recording of the trust deed or
mortgage and the date of the future advance, and notwithstanding that the
beneficiary or lender had actual knowledge of the intervening junior trust deeds
or mortgages and other liens at the time of the advance. In most states, the
trust deed or mortgage lien securing mortgage loans of the type which includes
home equity credit lines applies retroactively to the date of the original
recording of the trust deed or mortgage, provided that the total amount of
advances under the home equity credit line does not exceed the maximum specified
principal amount of the recorded trust deed or mortgage, except as to advances
made after receipt by the lender of a written notice of lien from a judgment
lien creditor of the trustor.

CONSUMER PROTECTION LAWS

      Numerous federal and state consumer protection laws impose substantive
requirements upon mortgage lenders in connection with the originating, servicing
and enforcing of loans secured by single family properties. These laws include
the federal Truth-in-Lending Act and Regulation Z promulgated thereunder, Real
Estate Settlement Procedures Act and Regulation B promulgated thereunder, Equal
Credit Opportunity Act, Fair Credit Billing Act, Fair Credit Reporting Act and
related statutes and regulations. In particular, Regulation Z requires certain
disclosures to borrowers regarding the terms of the loans; the Equal Credit
Opportunity Act and Regulation B promulgated thereunder prohibit discrimination
in the extension of credit 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; and the Fair Credit
Reporting Act regulates the use and reporting of information related to the
borrower's credit experience. Certain provisions of these laws impose specific
statutory liabilities upon lenders who fail to comply therewith. In addition,
violations of such laws may limit the ability of the servicer to collect all or
part of the principal of or interest on the loans and could subject the sellers
and in some cases their assignees to damages and administrative enforcement.

                         FEDERAL INCOME TAX CONSEQUENCES

      The following discussion summarizes the anticipated material federal
income tax consequences of the purchase, ownership and disposition of the
securities, as based on the advice of Chapman and Cutler LLP, special tax
counsel to the Issuer. This summary is based on the Internal Revenue Code of
1986, as amended (the "Code"), regulations (including the REMIC regulations
promulgated by the Treasury Department (the "REMIC Regulations")), rulings and
decisions in effect as of the date of this prospectus, all of which are subject
to change. This summary does not address federal income tax consequences
applicable to all categories of investors, some of which (such as banks and
insurance companies) may be subject to special rules. In addition, the summary
is limited to investors who will hold the securities as "capital assets"
(generally, property held for investment) as defined in section 1221 of the
Code. Investors should consult their own tax advisors in determining the
federal, state, local and any other tax consequences to them of the purchase,
ownership and disposition of the securities. As applied to any particular class
or series of securities, the summary is subject to further discussion or change
as provided in the related prospectus supplement.

OVERVIEW

      The federal income tax consequences applicable with respect to a specific
series of securities will vary depending on whether an election is made to treat
the trust estate relating to such series of securities as a real estate mortgage
investment conduit ("REMIC") under Code. The prospectus supplement for each
series of securities will specify whether a REMIC election will be made with
respect to such series. Securities of any series that is not the subject of a
REMIC election ("non-REMIC securities")

                                       84


are intended to be classified as indebtedness of the Issuer for federal income
tax purposes.

NON-REMIC SECURITIES

      General. If a REMIC election is not made, Chapman and Cutler LLP will
deliver its opinion that, although no regulations, published rulings or judicial
decisions exist that specifically discuss the characterization for federal
income tax purposes of securities with terms substantially the same as the
non-REMIC securities, in its opinion such securities will be treated for federal
income tax purposes as indebtedness of the Issuer and not as an ownership
interest in the collateral or an equity interest in the Issuer.

      Status as Real Property Loans. Because, in such counsel's opinion, the
non-REMIC securities will be treated as indebtedness of the Issuer for federal
income tax purposes, (i) such securities held by a thrift institution taxed as 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), (ii) interest on non-REMIC securities held by a real estate
investment trust will not be treated as "interest on obligations secured by
mortgages on real property or on interests in real property" within the meaning
of Code section 856(c)(3)(b), and non-REMIC securities will not constitute
"real estate assets" or "government securities" within the meaning of Code
section 856(c)(4)(A), and (iii) non-REMIC securities held by a regulated
investment company will not constitute "government securities" within the
meaning of Code section 851(b)(4)(A)(i).

      Interest on Non-REMIC Securities. Except as described below with respect
to original issue discount, market discount or premium, interest paid or accrued
on non-REMIC securities generally will be treated as ordinary income to the
holder, and will be includible in income in accordance with such holder's
regular method of accounting.

      Original Issue Discount. All accrual securities will be, and some or all
of the other securities may be, issued with "original issue discount" within
the meaning of Code section 1273(a). Holders of any class of securities having
original issue discount must generally include original issue discount in
ordinary gross income for federal income tax purposes as it accrues, in
accordance with the constant yield method, in advance of receipt of the cash
attributable to such income. When required by the Code and/or applicable
regulations, the Issuer will indicate on the face of each security issued by it
information concerning the application of the original issue discount rules to
such security and certain other information that may be required. The Issuer
will report annually to the Internal Revenue Service (the "IRS") and to holders
of record of such securities information with respect to the original issue
discount accruing on such securities during the reporting period.

      Rules governing original issue discount are set forth in Code sections
1271 through 1273, 1275 and 1281 through 1283 and in regulations issued
thereunder (the "OID Regulations"). The Code or the OID Regulations either do
not address, or are subject to varying interpretations with respect to, several
issues relevant to obligations, such as the securities, that are subject to
prepayment. Therefore, there is some uncertainty as to the

                                       85


manner in which the original issue discount rules of the Code will be applied to
the securities.

      Original Issue Discount Defined. In general, each security will be treated
as a single installment obligation for purposes of determining the original
issue discount includible in a securityholder's income. The amount of original
issue discount on such a security is the excess of the stated redemption price
at maturity of the security over its issue price. The issue price of a security
is the initial offering price to the public at which a substantial amount of the
securities of that class are First sold to the public (excluding bond houses,
brokers, underwriters or wholesalers), generally as set forth on the cover page
of the prospectus supplement for a series of securities. If less than a
substantial amount of a particular class of securities is sold for cash on or
prior to the date of the their initial issuance, the issue price for such class
will likely be treated as equal to its fair market value on the closing date.
The portion of the initial offering price which consists of payment for interest
accrued on the securities prior to the closing date generally may, at the option
of the initial securityholders, be subtracted from the issue price of the
securities and treated as an offset to interest received on the First payment
date.

      The stated redemption price at maturity of a security is equal to the
total of all payments to be made on the security other than "qualified stated
interest payments. "Qualified stated interest payments" are payments on the
securities which are paid at least annually and are based on either a Fixed rate
or a "qualified variable rate." Under the OID Regulations, interest is treated
as payable at a "qualified variable rate" and not as contingent interest if,
generally, (i) such interest is unconditionally payable at least annually, (ii)
the issue price of the security does not exceed the total noncontingent
principal payments and (iii) interest is based on a "qualified floating rate,"
an "objective rate," or a combination of "qualified floating rates" that do
not operate in a manner that significantly accelerates or defers interest
payments on such security. Generally, the stated redemption price at maturity of
a security (other than an accrual security or a payment lag security, as defined
below) is its stated principal amount; the stated redemption price at maturity
of an accrual security is the sum of all payments (regardless of how
denominated) scheduled to be received on such security under the Tax Prepayment
Assumption (as defined below). Any payment denominated as interest that does not
constitute a qualified stated interest payment is generally referred to as a
"contingent interest payment." The related prospectus supplement will discuss
whether the payments on a security denominated as interest are qualified stated
interest payments and the treatment for federal income tax purposes of any
contingent interest payments.

      De Minimis Original Issue Discount. Notwithstanding the general
definitions of original issue discount above, any original issue discount with
respect to a security will be considered to be zero if such discount is less
than 0.25% of the stated redemption price at maturity of the security multiplied
by its weighted average life (a "de minimis" amount). The weighted average life
of a security for this purpose is the sum of the following amounts (computed for
each payment included in the stated redemption price at maturity of the
security): (i) the number of complete years (rounded down for partial years)
from the closing date until the date on which each such payment is scheduled to

                                       86


be made under the Tax Prepayment Assumption, multiplied by(ii) a fraction, the
numerator of which is the amount of the payment, and the denominator of which is
the security's stated redemption price at maturity. Securityholders generally
must report de minimis original issue discount pro rata as principal payments
are received, and such income will be capital gain if the security is held as a
capital asset. However, accrual method holders may elect to accrue all interest
on a security, including de minimis original issue discount and market discount
and as adjusted by any premium, under a constant yield method.

      Accrual of Original Issue Discount. The Code requires that the amount and
rate of accrual of original issue discount be calculated based on a reasonable
assumed prepayment rate for the mortgage loans, the mortgage loans underlying
any mortgaged-backed securities and/or other mortgage collateral securing the
securities (the "Tax Prepayment Assumption") and prescribes a method for
adjusting the amount and rate of accrual of such discount if actual prepayment
rates exceed the Tax Prepayment Assumption. However, if such mortgage loans
prepay at a rate slower than the Tax Prepayment Assumption, no deduction for
original issue discount previously accrued, based on the Tax Prepayment
Assumption, is allowed. The Tax Prepayment Assumption is required to be
determined in the manner prescribed by regulations that have not yet been
issued. It is anticipated that the regulations will require that the Tax
Prepayment Assumption be the prepayment assumption that is used in determining
the initial offering price of such securities. The related prospectus supplement
for each series of securities will specify the Tax Prepayment Assumption
determined by the Issuer for the purposes of determining the amount and rate of
accrual of original issue discount. No representation is made that the mortgage
collateral will prepay at the Tax Prepayment Assumption or at any other rate.

      Generally, a security holder must include in gross income the sum of the
"daily portions," as determined below, of the original issue discount that
accrues on a security for each day the securityholder holds that security,
including the purchase date but excluding the disposition date. In the case of
an original holder of a security, a calculation will be made of the portion of
the original issue discount that accrues during each successive period (or
shorter period from date of original issue) (an "accrual period") that ends on
the day in the calendar year corresponding to each of the payment dates on the
securities (or the date prior to each such date). This will be done, in the case
of each full accrual period, by:

            (1) adding (A) the present value at the end of the accrual period of
      all remaining payments to be received on the securities, computed taking
      into account (i) the yield to maturity of the security at the issue date,
      (ii) events (including actual prepayments) that have occurred prior to the
      end of the accrual period, and (iii) the Tax Prepayment Assumption, and
      (B) any payments received during such accrual period, other than payments
      of qualified stated interest, and

            (2) subtracting from that total the "adjusted issue price" of the
      securities at the beginning of such accrual period.

                                       87


The adjusted issue price of a security at the beginning of the initial accrual
period is its issue price; the adjusted issue price of a security at the
beginning of a subsequent accrual period is the adjusted issue price at the
beginning of the immediately preceding accrual period plus the amount of
original issue discount allocable to such accrual period and reduced by the
amount of any payment other than a payment of qualified stated interest made at
the end of or during such accrual period. The original issue discount accrued
during such accrual period will then be divided by the number of days in the
period to determine the daily portion of original issue discount for each day in
the period. With respect to an initial accrual period shorter than a full
accrual period, the daily portions of original issue discount must be determined
according to any reasonable method, provided that such method is consistent with
the method used to determine yield on the securities.

      With respect to any security that is a variable rate debt instrument, the
sum of the daily portions of original issue discount that is includible in the
holder's gross income is determined under the same principles described above,
with the following medications: the yield to maturity on the securities should
be calculated as if the interest index remained at its value as of the issue
date of such securities. Because the proper method of adjusting accruals of
original issue discount on a variable rate debt instrument as a result of
prepayments is uncertain, holders of such instruments should consult their own
tax advisors regarding the appropriate treatment of such securities for federal
income tax purposes.

      Subsequent Purchasers of Securities with Original Issue Discount. A
subsequent purchaser of an accrual security or any other security issued with
original issue discount who purchases the security at a cost less than the
remaining stated redemption price at maturity, will also be required to include
in gross income for all days during his or her taxable year on which such
security is held, the sum of the daily portions of original issue discount on
the security. In computing the daily portions of original issue discount with
respect to a security for such a subsequent purchaser, however, the daily
portion for any day shall be reduced by the amount that would be the daily
portion for such day (computed in accordance with the rules set forth above)
multiplied by a fraction, the numerator of which is the amount, if any, by which
the price paid by such holder for the security exceeds its adjusted issue price
(the "acquisition premium"), and the denominator of which is the amount by
which the remaining stated redemption price at maturity exceeds the adjusted
issue price.

      Premium. A holder who purchases a security at a cost greater than its
stated redemption price at maturity generally will be considered to have
purchased the security at a premium, which it may elect to amortize as an offset
to interest income on such security (and not as a separate deduction item) on a
constant yield method. Although no regulations addressing the computation of
premium accrual on securities similar to the securities have been issued, the
legislative history of the Tax Reform Act of 1986 indicates that premium is to
be accrued in the same manner as market discount. Accordingly, it appears that
the accrual of premium on a class of securities of a series will be calculated
using the prepayment assumption used in pricing such class. If a holder makes an
election to amortize premium on a security, such election will apply to

                                       88


all taxable debt instruments (including all REMIC regular interests and all
pass-through certificates representing ownership interests in a trust holding
debt obligations) held by the holder at the beginning of the taxable year in
which the election is made, and to all taxable debt instruments acquired
thereafter by such holder, and will be irrevocable without the consent of the
Internal Revenue Service. Purchasers who pay a premium for the securities should
consult their tax advisers regarding the election to amortize premium and the
method to be employed.

      Market Discount. The securities are subject to the market discount
provisions of Code sections 1276 through 1278. These rules provide that if a
subsequent holder of a security purchases it at a market discount, some or all
of any principal payment or of any gain recognized upon the disposition of the
security will be taxable as ordinary interest income. Market discount on a
security means the excess, if any, of (1) the sum of its issue price and the
aggregate amount of original issue discount includible in the gross income of
all holders of the security prior to the acquisition by the subsequent holder
(presumably adjusted to reflect prior principal payments), over (2) the price
paid by the holder for the security. Market discount on a security will be
considered to be zero if such discount is less than .25% of the stated
redemption price at maturity of such security multiplied by its weighted average
life, which presumably would be calculated in a manner similar to weighted
average life (described above), taking into account distributions (including
prepayments) prior to the date of acquisition of such security by the subsequent
purchaser. If market discount on a security is treated as zero under this rule,
the actual amount of such discount must be allocated to the remaining principal
distributions on such security and when each such distribution is made, gain
equal to the discount allocated to such distribution will be recognized.

      Any principal payment (whether a scheduled payment or a prepayment) or any
gain on the disposition of a market discount security is to be treated as
ordinary income to the extent that it does not exceed the accrued market
discount at the time of such payment or disposition. The amount of accrued
market discount for purposes of determining the tax treatment of subsequent
principal payments or dispositions of the securities is to be reduced by the
amount so treated as ordinary income.

      The Tax Reform Act of 1986 grants authority to the U.S. Treasury to issue
regulations providing for the computation of accrued 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 U.S. Treasury, certain rules
described in the legislative history accompanying the Tax Reform Act of 1986
will apply. Under those rules, the holder of a market discount security may
elect to accrue market discount either on the basis of a constant interest rate
or using one of the following methods. For securities issued with original issue
discount, the amount of market discount that accrues during a period is equal to
the product of (i) the total remaining market discount, multiplied by (ii) a
fraction, the numerator of which is the original issue discount accruing during
the period and the denominator of which is the total remaining original issue
discount at the beginning of the period. For securities issued without original
issue discount, the amount of market discount that accrues during a period is
equal to the product of (i) the total remaining market discount, multiplied by
(ii) a fraction, the

                                       89


numerator of which is the amount of stated interest paid during the accrual
period and the denominator of which is the total amount of stated interest
remaining to be paid at the beginning of the period. For purposes of calculating
market discount under any of the above methods in the case of instruments (such
as the securities) that provide for payments that may be accelerated by reason
of prepayments of other obligations securing such instruments, the same
prepayment assumption applicable to calculating the accrual of original issue
discount shall apply. Regulations are to provide similar rules for computing the
accrual of amortizable security premium on instruments payable in more than one
principal installment. As an alternative to the inclusion of market discount in
income on the foregoing basis, the holder may elect to include such market
discount in income currently as it accrues on all market discount instruments
acquired by such holder in that taxable year or thereafter. In addition, accrual
method holders may elect to accrue all interest on a security, including de
minimis original issue discount and market discount and as adjusted by any
premium, under a constant yield method.

      A subsequent holder of a security who acquired the security at a market
discount also may be required to defer, until the maturity date of the security
or the earlier disposition of the security in a taxable transaction, the
deduction of a portion of the amount of interest that the holder paid or accrued
during the taxable year on indebtedness incurred or maintained to purchase or
carry the security in excess of the aggregate amount of interest (including
original issue discount) includible in his or her gross income for the taxable
year with respect to such security. The amount of such net interest expense
deferred in a taxable year may not exceed the amount of market discount accrued
on the security for the days during the taxable year on which the subsequent
holder held the security, and the amount of such deferred deduction to be taken
into account in the taxable year in which the security is disposed of in a
transaction in which gain or loss is not recognized in whole or in part is
limited to the amount of gain recognized on the disposition. This deferral rule
does not apply to a holder that elects to include market discount in income
currently as it accrues on all market discount instruments acquired by such
holder in that taxable year or thereafter.

      Because the regulations described above with respect to market discounts
and premiums have not been issued, it is impossible to predict what effect those
regulations might have on the tax treatment of a security purchased at a
discount or premium in the secondary market.

      Election to Treat All Interest as Original Issue Discount. The OID
Regulations permit a holder of a security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method for securities acquired on
or after April 4, 1994. If such an election were to be made with respect to a
security with market discount, the holder of the security would be deemed to
have made an election to include in income currently market discount with
respect to all other debt instruments having market discount that such holder of
the securities acquires during the year of the election or thereafter.
Similarly, a holder of a security that makes this election for a security that
is acquired at a premium will be deemed to have made an election to amortize
security premium with respect to all debt instruments having amortizable
security premium that such holder

                                       90


owns or acquires. The election to accrue interest, discount and premium on a
constant yield method with respect to a security is irrevocable.

      Sale or Redemption. If a security is sold, exchanged, redeemed or retired,
the seller will recognize gain or loss equal to the difference between the
amount realized on the sale and the seller's adjusted basis in the security.
Such adjusted basis generally will equal the cost of the security to the seller,
increased by any original issue discount and market discount included in the
seller's gross income with respect to the security and reduced by payments,
other than payments of qualified stated interest, previously received by the
seller and by any amortized premium. If a security holder is a bank, thrift or
similar institution described in section 582(c) of the Code, gain or loss
realized on the sale or exchange of a security will be taxable as ordinary
income or loss. Any such gain or loss recognized by any other seller generally
will be capital gain or loss provided that the security is held by the seller as
a "capital asset" (generally, property held for investment) within the meaning
of Code section 1221. Such gain or loss will be long-term gain or loss if the
security is held as a capital asset for more than one year. Long-term capital
gains of non-corporate taxpayers are subject to reduced maximum rates while
short-term capital gains are taxable at ordinary rates. The use of capital
losses is subject to limitations.

REMIC SECURITIES

      General. If a REMIC election is made with respect to a series of
securities, Chapman and Cutler LLP will deliver an opinion generally to the
effect that, under existing law, assuming timely filing of a REMIC election and
ongoing compliance with all provisions of the related Agreements, all or a
portion of the trust estate securing such series of securities will qualify as a
REMIC for federal income tax purposes.

      The securities in such series will be designated either as one or more
"regular interests" in a REMIC, which generally are treated as debt for federal
income tax purposes, or as "residual interests" in a REMIC, which generally are
not treated as debt for such purposes but rather as representing rights and
responsibilities with respect to the taxable income or loss of the related
REMIC. The prospectus supplement for such series will indicate which classes of
securities are being designated as regular interests ("regular interest
securities") and which class is being designated as the residual interest
("residual interest securities").

      Tiered REMIC Structures. For certain series of securities, multiple
separate elections may be made to treat designated portions of the related trust
estate as REMICs (referred to as the "Upper Tier REMIC" and the "Lower Tier
REMIC(s)" respectively) for federal income tax purposes. Upon the issuance of
any such series of securities, Chapman and Cutler LLP will deliver its opinion
generally to the effect that, under existing law, assuming timely filing of
applicable REMIC elections and ongoing compliance with all provisions of the
related Agreements, the Upper Tier REMIC and each Lower Tier REMIC will each
qualify as a REMIC for federal income tax purposes. In certain cases, a single
residual interest security may represent the residual interest in both the Upper
Tier REMIC and each Lower Tier REMIC. In such case, the discussion

                                       91


of residual interest securities set forth below should be interpreted as
applying to each residual interest separately.

      Status as Real Property Loans. Except to the extent otherwise provided in
the related prospectus supplement: (i) REMIC securities held by a "domestic
building and loan association" will constitute assets described in Code section
7701(a)(19)(C)(xi); (ii) REMIC securities held by a "real estate investment
trust" ("REIT") will constitute "real estate assets" within the meaning of
Code section 856(c)(4)(A) and interest on such securities will be considered
"interest on obligations secured by mortgages on real property" within the
meaning of Code section 856(c)(3)(B); and (iii) regular interest securities held
by a "financial assets securitization investment trust" ("FASIT") will qualify
for treatment as "permitted assets" within the meaning of Code section
860L(c)(1)(G) and as "qualified mortgages" within the meaning of Code section
860G(a)(3) of if held by another REMIC. REMIC securities held by REITs or
regulated investment companies will not constitute "government securities"
within the meaning of Code section 856(c)(5)(A) or 851(b)(4)(A)(ii),
respectively. REMIC securities held by certain Financial institutions will
constitute "evidences of indebtedness" within the meaning of Code section
582(c)(1).

      In the case of items (i), (ii) and (iii) above, if less than 95% of the
REMIC's assets are assets qualifying under any of the foregoing Code sections,
the REMIC securities will be qualifying assets only to the extent that the
REMIC's assets are qualifying assets. If a series of securities employs a
multi-tier REMIC structure, both the Upper Tier REMIC and the Lower Tier REMIC
will be treated as a single REMIC for purposes of determining the extent to
which the related REMIC securities and the income thereon will be treated as
such assets and income.

   TAXATION OF REGULAR INTEREST SECURITIES.

      General. Except as otherwise stated in this discussion, regular interest
securities 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.
Holders of regular interest securities that otherwise report income under a cash
method of accounting will be required to report income with respect to regular
interest securities under an accrual method.

      Original Issue Discount. Certain classes of regular interest securities
may be issued with original issue discount within the meaning of section 1273(a)
of the Code. The rules governing original issue discount with respect to a
regular interest security are described above under "Non-REMIC Securities --
Original Issue Discount." Holders of regular interest securities should be
aware, however, that the OID Regulations do not adequately address certain
issues relevant to prepayable securities, such as the regular interest
securities. In view of the complexities and current uncertainties as to the
manner of inclusion in income of original issue discount on regular interest
securities, each investor should consult his own tax advisor to determine the
appropriate amount and method of inclusion in income of original issue discount
on such regular interest securities for federal income tax purposes.

                                       92


      Although unclear at present, the depositor intends to treat interest on a
regular interest security that is a weighted average of the net interest rates
on mortgage loans as qualified stated interest. In such case, the weighted
average rate used to compute the initial pass-through rate on the regular
interest securities will be deemed to be the index in effect through the life of
the regular interest securities. It is possible, however, that the IRS may treat
some or all of the interest on regular interest securities with a weighted
average rate as taxable under the rules relating to obligations providing for
contingent payments. Such treatment may effect the timing of income accruals on
such regular interest securities.

      Market Discount. A subsequent purchaser of a regular interest security may
also be subject to the market discount provisions of Code sections 1276 through
1278. These rules are described above under "Non-REMIC Securities -- Market
Discount."

      Premium. The rules governing ""premium" apply equally to regular interest
securities (see above "Non-REMIC Securities -- Premium").

      Effects of Defaults and Delinquencies. Certain series of securities may
contain one or more classes of subordinated securities, and in the event there
are defaults or delinquencies on the mortgage assets, amounts that would
otherwise be distributed on the subordinated securities may instead be
distributed on the senior securities. Subordinated securityholders nevertheless
will be required to report income with respect to such securities under an
accrual method without giving effect to delays and reductions in distributions
on such subordinated securities attributable to defaults and delinquencies on
the mortgage assets, except to the extent that it can be established that such
amounts are uncollectible. As a result, the amount of income reported by a
subordinated security holder in any period could significantly exceed the amount
of cash distributed to such holder in that period. The holder will eventually be
allowed a loss (or will be allowed to report a lesser amount of income) to the
extent that the aggregate amount of distributions on the subordinated security
is reduced as a result of defaults and delinquencies on the mortgage assets.

      Treatment of Realized Losses. Although not entirely clear, it appears that
holders of securities that are corporations should in general be allowed to
deduct as an ordinary loss any loss sustained during the taxable year on account
of any such securities becoming wholly or partially worthless, and that, in
general, holders of securities that are not corporations should be allowed to
deduct as a short-term capital loss any loss sustained during the taxable year
on account of any such securities becoming wholly worthless. Although the matter
is not entirely clear, non-corporate holders of securities may be allowed a bad
debt deduction at such time that the principal balance of any such security is
reduced to reflect realized losses resulting from any liquidated mortgage
assets. The Internal Revenue Service, however, could take the position that
non-corporate holders will be allowed a bad debt deduction to reflect realized
losses only after all mortgage assets remaining in the related trust fund have
been liquidated or the securities of the related series have been otherwise
retired. Potential investors and holders of the securities are urged to consult
their own tax advisors regarding the appropriate timing, amount and character of
any loss sustained with respect to such

                                       93


securities, including any loss resulting from the failure to recover previously
accrued interest or discount income. Special loss rules are applicable to banks
and thrift institutions, including rules regarding reserves for bad debts. Such
taxpayers are advised to consult their tax advisors regarding the treatment of
losses on securities.

      Sale or Exchange. If a regular interest security is sold, exchanged,
redeemed or retired, the holder will recognize gain or loss equal to the
difference between the amount realized on such disposition and the adjusted
basis in the regular interest security. Similarly, a holder who receives a
payment denominated as principal with respect to a regular interest security
will recognize gain equal to the excess of the amount of such payment over his
adjusted basis in the regular interest security. A holder that receives a final
payment that is less than the holder's adjusted basis in a regular interest
security will generally recognize a loss. The adjusted basis of a regular
interest security generally will equal the cost of the regular interest security
to the holder, increased by any original issue discount or market discount
previously included in the holder's gross income with respect to the regular
interest security, and reduced by payments (other than payments of qualified
stated interest) previously received by the holder on the regular interest
security and by any amortized premium.

      Except as note above with respect to market discount and except as noted
below, any such gain or loss on a regular interest security generally will be
capital gain or loss. Such gain or loss will be long-term gain or loss if the
regular interest security is held as a capital asset for more than one year.
Long-term capital gains of non-corporate taxpayers are subject to reduced
maximum rates while short-term capital gains are taxable at ordinary rates. The
use of capital losses is subject to limitations.

      If the holder of a regular interest security is a bank, a mutual savings
bank, a thrift, or a similar institution described in section 582 of the Code,
any gain or loss on the sale or exchange of the regular interest security will
be treated as ordinary income or loss.

      In the case of other types of holders, gain from the disposition of a
regular interest security that otherwise would be capital gain will be treated
as ordinary income to the extent that the amount actually includible in income
with respect to the regular interest security by the holder during his holding
period is less than the amount that would have been includible in income if the
yield on that regular interest security during the holding period had been 110%
of a specified U.S. Treasury borrowing rate as of the date that the holder
acquired the regular interest security. Although the relevant legislative
history indicates that the portion of the gain from disposition of a regular
interest security that will be recharacterized as ordinary income is limited to
the amount of original issue discount (if any) on the regular interest security
that was not previously includible in income, the applicable Code provision
contains no such limitation.

   TAXATION OF HOLDERS OF RESIDUAL INTEREST SECURITIES.

      The REMIC will not be subject to Federal income tax except with respect to
income from prohibited transactions and certain other transactions. See "--
Prohibited Transactions and Contributions Tax" below. Instead, the original
holder of a security representing a residual interest (a "residual interest
security") will report on its federal

                                       94


income tax return, as ordinary income, the "daily portion" of the taxable
income or net loss of the REMIC for each day during the taxable year on which
such holder held the residual interest security. The daily portion is determined
by allocating to each day in any calendar quarter its ratable portion of the
taxable income or net loss of the REMIC for such quarter, and by allocating that
amount among the holders (on such day) of the residual interest securities in
proportion to their respective holdings on such day.

      The taxable income of the REMIC will be determined under an accrual method
and will be taxable to the holders of residual interest securities without
regard to the timing or amounts of cash distributions by the REMIC. Ordinary
income derived from residual interest securities will be "portfolio income" for
purposes of the taxation of taxpayers subject to the limitations on the
deductibility of "passive losses." As residual interests, the residual interest
securities will be subject to tax rules, described below, that differ from those
that would apply if the residual interest securities were treated for federal
income tax purposes as direct ownership interests in the mortgage assets or as
debt instruments issued by the REMIC.

      The holder of a residual interest security may be required to include
taxable income from the residual interest security in excess of the cash
distributed. The reporting of taxable income without corresponding distributions
could occur, for example, in certain REMIC issues in which the loans held by the
REMIC were issued or acquired at a discount, since mortgage prepayments cause
recognition of discount income, while the corresponding portion of the
prepayment could be used in whole or in part to make principal payments on REMIC
Regular Interests issued without any discount or at an insubstantial discount
(if this occurs, it is likely that cash distributions will exceed taxable income
in later years). Taxable income may also be greater in earlier years of certain
REMIC issues as a result of the fact that interest expense deductions, as a
percentage of outstanding principal on REMIC regular interest securities, will
typically increase over time as lower yielding securities are paid, whereas
interest income with respect to loans will generally remain constant over time
as a percentage of loan principal.

      In any event, because the holder of a residual interest security is taxed
on the net income of the REMIC, the taxable income derived from a residual
interest security in a given taxable year will not be equal to the taxable
income associated with investment in a corporate security or stripped instrument
having similar cash flow characteristics and pretax yield. Therefore, the
after-tax yield on the residual interest security may be less than that of such
a security or instrument.

      A subsequent residual interest security holder also will report on its
federal income tax return amounts representing a daily share of the taxable
income of the REMIC for each day that such residual interest security holder
owns such residual interest security. Those daily amounts generally would equal
the amounts that would have been reported for the same days by an original
residual interest security holder, as described above. The legislative history
to the Code provisions governing this matter indicates that certain adjustments
may be appropriate to reduce (or increase) the income of a subsequent holder of
a residual interest security that purchased such residual interest security at a

                                       95


price greater than (or less than) the adjusted basis such residual interest
security would have in the hands of an original residual interest security-
holder. See "-- Sale or Exchange" below. It is not clear, however, whether such
adjustments will in fact be permitted or required and, if so, how they would be
made. The REMIC Regulations do not provide for any such adjustments.

      Limitation on Losses. The REMIC will have a net loss for any calendar
quarter in which its deductions exceed its gross income. The amount of the
REMIC's net loss that a holder may take into account currently is limited to the
holder's adjusted basis at the end of the calendar quarter in which such loss
arises. A holder's basis in a residual interest security will initially equal
such holder's purchase price, and will subsequently be increased by the amount
of the REMIC's taxable income allocated to the holder, and decreased (but not
below zero) by the amount of distributions made and the amount of the REMIC's
net loss allocated to the holder. Any disallowed loss may be carried forward
indefinitely, but may be used only to offset income of the REMIC generated by
the same REMIC. The ability of holders of residual interest securities to deduct
net losses may be subject to additional limitations under the Code, as to which
such holders should consult their tax advisers.

      Distributions. Distributions on a residual interest security (whether at
their scheduled times or as a result of prepayments) will generally not result
in any additional taxable income or loss to a holder of a residual interest
security. If the amount of such payment exceeds a holder's adjusted basis in the
residual interest security, however, the holder will recognize gain (treated as
gain from the sale of the residual interest security) to the extent of such
excess.

      Sale or Exchange. A holder of a residual interest security will recognize
gain or loss on the sale or exchange of a residual interest security equal to
the difference, if any, between the amount realized and such holder's adjusted
basis in the residual interest security at the time of such sale or exchange. In
general, any such gain or loss will be capital gain or loss provided the
residual interest security is held as a capital asset. However, residual
interest securities will be "evidences of indebtedness" within the meaning of
Code Section 582(c)(1), so that gain or loss recognized from sale of a residual
interest security by a bank or thrift institution to which such section applies
would be ordinary income or loss. Any loss upon disposition of a residual
interest security may be disallowed if the selling holder acquires any residual
interest in a REMIC or similar mortgage pool within six months before or after
such disposition. In that event, any loss will increase such regular interest
securityholder's adjusted basis in the newly acquired interest.

      Excess Inclusions. The excess inclusion portion of a REMIC's income is
generally equal to the excess, if any, of (a) REMIC taxable income for the
quarterly period allocable to a residual interest security, over (b) the daily
accruals for such quarterly period. For this purpose, daily accruals are
determined by allocating to each day in the calendar quarter its ratable portion
of the "adjusted issue price" of the residual interest security at the
beginning of such quarterly period and 120% of the long term applicable federal
rate in effect on the date the residual interest security is issued. The
adjusted

                                       96


issue price of a residual interest at the beginning of each calendar quarter
will equal its issue price (calculated in a manner analogous to the
determination of the issue price of a Regular Interest), increased by the
aggregate of the daily accruals for prior calendar quarters, and decreased (but
not below zero) by the amount of loss allocated to a holder and the amount of
distributions made on the residual interest security before the beginning of the
quarter. The long-term federal rate, which is announced monthly by the Treasury
Department, is an interest rate that is based on the average market yield of
outstanding marketable obligations of the United States government having
remaining maturities in excess of nine years.

      The portion of the REMIC taxable income of a holder of a residual interest
security consisting of "excess inclusion" income will be subject to federal
income tax in all events and may not be offset by unrelated deductions or
losses, including net operating losses, on such holder's federal income tax
return. Further, if the holder of a residual interest security is an
organization subject to the tax on unrelated business income imposed by Code
section 511, such holder's excess inclusion income will be treated as unrelated
business taxable income of such holder. If a residual interest security is owned
by a foreign person, excess inclusion income is subject to tax at a rate of 30%
which may not be reduced by treaty, is not eligible for treatment as "portfolio
interest" and is subject to certain additional limitations. The Small Business
Job Protection Act of 1996 has eliminated the special rule permitting section
593 institutions ("thrift institutions") to use net operating losses and other
allowable deductions to offset their excess inclusion income from REMIC residual
securities that have "significant value" within the meaning of the REMIC
Regulations, effective for taxable years beginning after December 31, 1995,
except with respect to residual securities continuously held by a thrift
institution since November 1, 1995.

      In the case of any residual interest securities held by a real estate
investment trust, the Code provides that under regulations to be issued the
aggregate excess inclusions with respect to such residual interest securities,
reduced (but not below zero) by the real estate investment trust taxable income
(within the meaning of Code Section 857(b)(2), excluding any net capital gain),
will be allocated among the shareholders of such trust in proportion to the
dividends received by such shareholders from such trust, and any amount so
allocated will be treated as an excess inclusion with respect to a residual
interest security as if held directly by such shareholder. Regulated investment
companies, common trust funds and certain cooperatives are subject to similar
rules. No such regulations have been issued to date and it is unclear how this
provision would be applied in practice.

      In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect of excess inclusions on the alternative minimum
taxable income of a residual holder. First, alternative minimum taxable income
for such residual holder is determined without regard to the special rule that
taxable income cannot be less than excess inclusions. Second, a residual
holder's alternative minimum taxable income for a tax year cannot be less than
excess inclusions for the year. Third, the amount of any alternative minimum tax
net operating loss deductions must be computed without regard to any excess
inclusions.

                                       97



      Restrictions on Ownership and Transfer of Residual Interest Securities. As
a condition to qualification as a REMIC, reasonable arrangements must be made to
prevent the ownership of a residual interest security by any "disqualified
organization. Disqualified organizations include the United States, any State
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing, a rural
electric or telephone cooperative described in section 1381(a)(2)(C) of the
Code, or any entity exempt from the tax imposed by sections 1-1399 of the Code,
if such entity is not subject to tax on its unrelated business income.
Accordingly, the applicable Pooling and Servicing Agreement will prohibit
disqualified organizations from owning a residual interest security. In
addition, no transfer of a residual interest security will be permitted unless
the proposed transferee shall have furnished to the Trustee an affidavit
representing and warranting that it is neither a Disqualified Organization nor
an agent or nominee acting on behalf of a Disqualified Organization.

      If a residual interest security is transferred to a Disqualified
Organization (in violation of the restrictions set forth above), a substantial
tax will be imposed on the transferor of such residual interest security at the
time of the transfer. In addition, if a Disqualified Organization holds an
interest in a pass-through entity (including, among others, a partnership,
trust, real estate investment trust, regulated investment company, or any person
holding as nominee), that owns a residual interest security, the pass-through
entity will be required to pay an annual tax on its allocable share of the
excess inclusion income of the REMIC. The pass-through entity otherwise liable
for the tax, for any period during which the disqualified organization is the
record holder of an interest in such entity, will be relieved of liability for
the tax if such record holder furnishes to such entity an affidavit that such
record holder is not a disqualified organization and, for such period, the
pass-through entity does not have actual knowledge that the affidavit is false.
Except as may be provided in Treasury regulations not yet issued, any person
holding an interest in a pass-through entity as a nominee for another will, with
respect to such interest, be treated as a pass-through entity. Under the
Taxpayer Relief Act of 1997, large partnerships (generally with 250 or more
partners) will be taxable on excess inclusion income as if all partners were
disqualified organizations.

      Under the REMIC Regulations, if a residual interest security is a
"noneconomic residual interest," as described below, such transfer of a
residual interest security to a United States person will be disregarded for all
Federal tax purposes unless no significant purpose of the transfer was to impede
the assessment or collection of tax. A residual interest security is a
"noneconomic residual interest" unless at the time of the transfer (i) the
present value of the expected future distributions on the residual interest
security at least equals the product of the present value of the anticipated
excess inclusions and the highest rate of tax for the year in which the transfer
occurs, and (ii) the transferor reasonably expects that the transferee will
receive distributions from the REMIC at or after the time at which the taxes
accrue on the anticipated excess inclusions in an amount sufficient to satisfy
the accrued taxes. A significant purpose to impede the assessment or collection
of tax exists if the transferor, at the time of the transfer, either knew or
should have known that the transferee would be unwilling or unable to pay taxes

                                       98



due on its share of the taxable income of the REMIC. Under final regulations
issued by the Treasury Department on July 19, 2002, a transferor is presumed not
to have such knowledge if (i) the transferor conducted a reasonable
investigation of the financial condition of the transferee, (ii) the transferee
acknowledges to the transferor that the residual interest security may generate
tax liabilities in excess of the cash flow and the transferee represents that it
intends to pay such taxes associated with the residual interest security as they
become due, (iii) the transferee represents that it will not cause income from
the residual interest security to be attributable to a foreign permanent
establishment or fixed base of the transferee or another U.S. taxpayer and (iv)
the transfer satisfies either an "asset test" or "formula test". The "asset
test" requires that the transfer be to certain domestic taxable corporations
with large amounts of gross and net assets where an agreement is made that all
future transfers will be to taxable domestic corporations in transactions that
qualify for the aforementioned "safe harbor." The asset test is not satisfied
if the facts and circumstances known to the transferor reasonably indicate that
the taxes associated with the residual interest security will not be paid.
Meanwhile, the "formula test" requires that the present value of the
anticipated tax liabilities associated with holding the residual interest does
not exceed the sum of (i) the present value of any consideration given to the
transferee to acquire the interest, (ii) the present value of the expected
future distributions on the interest, and (iii) the present value of any
anticipated tax savings associated with holding the interest as the REMIC
generates losses. If a transfer of a "noneconomic residual security" is
disregarded, the transferor would continue to be treated as the owner of the
residual interest security and would continue to be subject to tax on its
allocable portion of the net income of the REMIC.

      Inducement Fees. The REMIC Regulations (i) require transferees of
noneconomic residual interests that receive payments made to induce the
acquisition of such interests ("inducement fees") to recognize such fees as
income over the expected remaining life of the acquired REMIC in a manner that
reasonably reflects the after-tax costs and benefits of holding the residual
interests, and (ii) specify that inducement fees constitute income from sources
within the United States. These regulations will apply to any inducement fee
received in connection with the acquisition of a residual interest security.

      Foreign Investors. The REMIC Regulations provide that the transfer of a
residual interest security that has a "tax avoidance potential" to a "foreign
person" will be disregarded for federal income tax purposes. This rule appears
to apply to a transferee who is not a U.S. Person unless such transferee's
income in respect of the residual interest security is effectively connected
with the conduct of a United Sates trade or business. A residual interest
security is deemed to have a tax avoidance potential unless, at the time of
transfer, the transferor reasonably expect that the REMIC will distribute to the
transferee amounts that will equal at least 30 percent of each excess inclusion,
and that such amounts will be distributed at or after the time the excess
inclusion accrues and not later than the end of the calendar year following the
year of accrual. If the non-U.S. Person transfers the residual interest security
to a U.S. Person, the transfer will be disregarded, and the foreign transferor
will continue to be treated as the owner, if the transfer has the effect of
allowing the transferor to avoid tax on accrued excess

                                       99



inclusions. The Agreements will provide that no residual interest security may
be transferred to a non-U.S. Person. In addition, no transfer of a residual
interest security will be permitted unless the proposed transferee shall have
furnished to the Trustee an affidavit representing and warranting that it is not
a Non-U.S. Person.

      The Agreements provide that any attempted transfer or pledge in violation
of the transfer restrictions shall be absolutely null and void and shall vest no
rights in any purported transferee. Investors in residual interest securities
are advised to consult their own tax advisors with respect to transfers of the
residual interest securities and, in addition, pass-through entities are advised
to consult their own tax advisors with respect to any tax which may be imposed
on a pass-through entity.

      Mark to Market Rules. Prospective purchasers of a residual interest
security should be aware that such a security acquired after January 3, 1995
cannot be marked-to-market.

      Administrative Matters. The REMIC's books must be maintained on a calendar
year basis and the REMIC must File an annual federal income tax return. The
REMIC will also be subject to the procedural and administrative rules of the
Code applicable to partnerships, including the determination of any adjustments
to, among other things, items of REMIC income, gain, loss, deduction, or credit,
by the IRS in a unified administrative proceeding.

   TAXATION OF THE REMIC

      General. Although a REMIC is a separate entity for federal income tax
purposes, a REMIC is not generally subject to entity-level tax. Rather, the
taxable income or net loss of a REMIC is taken into account by the holders of
residual interests. As described above, the regular interests are generally
taxable as debt of the REMIC.

      Qualification as a REMIC. The trust estate or one or more designated pools
of the assets of the trust estate may elect to be treated under the Code as a
REMIC in which the regular interest securities and residual interest securities
will constitute the "regular interests" and "residual interests,"
respectively, if a REMIC election is in effect and certain tests concerning (i)
the composition of the REMIC's assets and (ii) the nature of the holders'
interests in the REMIC are met on a continuing basis. A loss of REMIC status
could have a number of consequences for holders. If, as the result of REMIC
disqualification, the trust estate were treated as an association taxable as a
corporation, distributions on the security could be recharacterized in part as
dividends from a non-includible corporation and in part as returns of capital.
Alternatively, distributions on a regular interest security could continue to be
treated as comprised of interest and principal notwithstanding REMIC
disqualification, in which case a cash-basis holder might not be required to
continue to recognize interest and market discount with respect to the security
on a accrual basis. Under the first alternative, a loss of REMIC status would,
and under the second alternative, a loss of REMIC status could cause the
securities and the associated distributions not to be qualified assets and
income for the various purposes of domestic building and loan associations,
FASITs and REITs described under "REMIC Securities -- Status as Real Property
Loans" above, although

                                       100



such a loss would not Affect the status of the securities as "government
securities" for REITs. The securities should continue to qualify as "government
securities" for regulated investment companies, regardless of whether REMIC
status is lost.

      Calculation of REMIC Income. The taxable income or net loss of a REMIC is
determined under an accrual method of accounting and in the same manner as in
the case of an individual, with certain adjustments. In general, the taxable
income or net loss will be the difference between (i) the gross income produced
by the REMIC's assets, including stated interest and any original issue discount
or market discount on loans and other assets, and (ii) deductions, including
stated interest and original issue discount accrued on regular interest
securities, amortization of any premium with respect to loans, and servicing
fees and other expenses of the REMIC. A holder of a residual interest security
that is an individual or a "pass-through interest holder" (including certain
pass-through entities, but not including real estate investment trusts) will be
unable to deduct servicing fees payable on the loans or other administrative
expenses of the REMIC for a given taxable year, to the extent that such
expenses, when aggregated with such holder's other miscellaneous itemized
deductions for that year, do not exceed two percent of such holder's adjusted
gross income.

      For purposes of computing its taxable income or net loss, the REMIC should
have an initial aggregate tax basis in its assets equal to the aggregate fair
market value of the regular interests and the residual interests on the Startup
Day (generally, the day that the interests are issued). That aggregate basis
will be allocated among the assets of the REMIC in proportion to their
respective fair market values.

      The original issue discount provisions of the Code apply to loans of
individuals originated on or after March 2, 1984, and the market discount
provisions apply to loans originated after July 18, 1984. Subject to possible
application of the de minimis rules, the method of accrual by the REMIC of
original issue discount income on such loans will be equivalent to the method
under which securityholders accrue original issue discount (i.e., under the
constant yield method taking into account the Prepayment Assumption). The REMIC
will deduct original issue discount on the regular interest securities in the
same manner that the holders of the regular interest securities include such
discount in income, but without regard to the de minimis rules. See "Taxation
of Regular Interest Securities" above. However, a REMIC that acquires loans at a
market discount must include such market discount in income currently, as it
accrues, on a constant interest basis.

      To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the life
of the loans (taking into account the Prepayment Assumption) on a constant yield
method. Although the law is somewhat unclear regarding recovery of premium
attributable to loans originated on or before such date, it is possible that
such premium may be recovered in proportion to payments of loan principal.

      Prohibited Transactions and Contributions Tax. The REMIC will be subject
to a 100% tax on any net income derived from a "prohibited transaction."  For
this purpose,

                                       101



net income will be calculated without taking into account any losses from
prohibited transactions or any deductions attributable to any prohibited
transaction that resulted in a loss. In general, prohibited transactions
include: (i) subject to limited exceptions, the sale or other disposition of any
qualified mortgage transferred to the REMIC; (ii) subject to limited exceptions,
the sale or other disposition of a cash flow investment; (iii) the receipt of
any income from assets not permitted to be held by the REMIC pursuant to the
Code; or (iv) the receipt of any fees or other compensation for services
rendered by the REMIC. It is anticipated that a REMIC will not engage in any
prohibited transactions in which it would recognize a material amount of net
income. In addition, subject to a number of exceptions, a tax is imposed at the
rate of 100% on amounts contributed to a REMIC after the close of the
three-month period beginning on the Startup Day. The holders of residual
interest securities will generally be responsible for the payment of any such
taxes imposed on the REMIC. To the extent not paid by such holders or otherwise,
however, such taxes will be paid out of the trust fund and will be allocated pro
rata to all outstanding classes of securities of such REMIC.

WITHHOLDING WITH RESPECT TO CERTAIN FOREIGN INVESTORS

      Interest paid to or accrued by a beneficial owner of a security who is a
not a U.S. Person (a "foreign person") generally will be considered portfolio
interest and generally will not be subject to United States federal income tax
and withholding tax, provided the interest is not effectively connected with the
conduct of a trade or business within the United States by the foreign person
and the foreign person (i) is not actually or constructively a 10 percent
shareholder of the depositor or its affiliates or a controlled foreign
corporation with respect to which the depositor or its affiliates is a related
person (all within the meaning of the Code) and (ii) provides the Indenture
Trustee or other person who is otherwise required to withhold U.S. tax with
respect to the securities (the "withholding agent") with an appropriate
statement on Form W-8BEN (Certificate of Foreign Status of Beneficial Owner for
United States Tax Withholding). If a security is held through a securities
clearing organization or certain other financial institutions, the organization
or institution may provide the relevant signed statement to the withholding
agent; in that case, however, the signed statement must be accompanied by a Form
W-8BEN provided by the foreign person that owns the security. If the information
shown on Form W-8BEN changes, a new Form W-8BEN must be filed. If interest on
the securities is not portfolio interest, then it will be subject to United
States federal income and withholding tax at a rate of 30 percent, unless
reduced or eliminated pursuant to an applicable tax treaty.

      Under recently issued Treasury regulations, a payment to a foreign
partnership is treated, with some exceptions, as a payment directly to the
partners, so that the partners are required to provide any required
certifications. Foreign persons that intend to hold a security through a
partnership or other pass-through entity should consult their own tax advisors
regarding the application of those Treasury regulations to an investment in a
security.

      Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a security by a foreign person will be exempt from United
States federal

                                       102



income and withholding tax, provided that (i) such gain is not effectively
connected with the conduct of a trade or business in the United States by the
foreign person and (ii) in the case of a foreign person who is an individual,
the foreign person is not present in the United States for 183 days or more in
the taxable year.

      For purposes of this discussion, the term "U.S. Person" means (i) a
citizen or resident of the United States; (ii) a corporation (or entity treated
as a corporation for tax purposes) created or organized in the United States or
under the laws of the United States or of any state including the District of
Columbia; (iii) a partnership (or entity treated as a partnership for tax
purposes) organized in the United States or under the laws of the United States
or of any state including the District of Columbia (unless provided otherwise by
future Treasury regulations); (iv) an estate whose income is includible in gross
income for United States income tax purposes regardless of its source; or (v) 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 U.S. Persons
have authority to control all substantial decisions of the trust.
Notwithstanding the last clause of the preceding sentence, to the extent
provided in Treasury regulations, certain trusts that were in existence on
August 20, 1996, that were treated as U.S. Persons prior to such date and that
elect to continue to be treated as U.S. Persons also will be U.S. Persons.

BACKUP WITHHOLDING

      Under federal income tax law, a securityholder, beneficial owner,
financial intermediary or other recipient of a payment on behalf of a beneficial
owner may be subject to "backup withholding" under certain circumstances.
Backup withholding may apply to such person who is a United States person if
such person, among other things, (i) fails to furnish his social security number
or other taxpayer identification number, (ii) furnishes an incorrect taxpayer
identification number, (iii) fails to report properly interest and dividends, or
(iv) under certain circumstances, fails to provide a certified statement, signed
under penalties of perjury, that the taxpayer identification number provided is
correct and that such person is not subject to backup withholding. Backup
withholding may apply, under certain circumstances, to a securityholder who is
a Non-U.S. Person if the securityholder fails to provide securities broker with
a Foreign Person Certification. Backup withholding applies to "reportable
payments," which include interest payments and principal payments to the extent
of accrued original issue discount, as well as distributions of proceeds from
the sale of regular interest securities or residual interest securities. The
backup withholding rate is generally the fourth lowest rate of income tax as in
effect from time to time. Backup withholding, however, does not apply to
payments on a security made to certain exempt recipients, such as tax-exempt
organizations, and to certain Non-U.S. Persons. Securityholders should consult
their tax advisors for additional information concerning the potential
application of backup withholding to payments received by them with respect to a
security.

      DUE TO THE COMPLEXITY OF THE FEDERAL INCOME TAX RULES APPLICABLE TO
SECURITYHOLDERS AND THE CONSIDERABLE UNCERTAINTY THAT EXISTS WITH RESPECT TO
MANY ASPECTS OF THOSE RULES, POTENTIAL INVESTORS ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS REGARDING THE TAX TREATMENT OF THE ACQUISITION, OWNERSHIP, AND
DISPOSITION OF THE SECURITIES.

                                       103



                            STATE TAX CONSIDERATIONS

      In addition to the federal income tax consequences described above,
potential investors should consider the state income tax consequences of the
acquisition, ownership, and disposition of the securities. State income tax law
may differ substantially from the corresponding federal law, and this discussion
does not purport to describe any aspect of the income tax laws of any state.
Therefore, potential investors should consult their own tax advisors with
respect to the various state tax consequences of an investment in the
securities.

                              ERISA CONSIDERATIONS

      The following describes certain considerations under ERISA and Section
4975 of the Code, which apply only to securities of a series that are not
divided into subclasses. If securities are divided into subclasses, the
prospectus supplement will contain information concerning considerations
relating to ERISA and the Code that are applicable to such securities.

      ERISA and Section 4975 of the Code impose requirements on employee benefit
plans (and on certain other retirement plans and arrangements, including
individual retirement accounts and annuities and certain Keogh plans, and on
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested) (collectively "Plans") subject to ERISA or to
Section 4975 of the Code and on persons who are fiduciaries with respect to such
Plans. Generally, ERISA applies to investments made by Plans. Among other
things, ERISA requires that the assets of Plans be held in trust and that the
trustee, or other duly authorized fiduciary, have exclusive authority and
discretion to manage and control the assets of such Plans. ERISA also imposes
certain duties on persons who are fiduciaries of Plans. Under ERISA, any person
who exercises any discretionary authority or control respecting the management
or disposition of the assets of a Plan is considered to be a fiduciary of such
Plan (subject to certain exceptions not here relevant). Certain employee benefit
plans, such as 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 to ERISA requirements.
Accordingly, assets of such plans may be invested in securities without regard
to the ERISA considerations described above and below, subject to the provisions
of applicable state 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.

      In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA prohibits a broad range of transactions
involving Plan assets and persons ("Parties in Interest") having certain
specified relationships to a Plan and imposes additional prohibitions where
Parties in Interest are fiduciaries with respect to such Plan. Certain Parties
in Interest that participate in a prohibited transaction may be subject to
excise taxes imposed pursuant to Section 4975 of the Code, or a penalty imposed
pursuant to Section 502(i) of ERISA, unless a statutory, regulatory or
administrative exemption is available.

                                       104


      On November 13, 1986, the United States Department of Labor (the "DOL")
issued final regulations concerning the definition of what constitutes the
assets of a Plan. Under this regulation, the underlying assets and properties of
corporations, partnerships, trusts and certain other entities in which a Plan
acquires an "equity" interest could be deemed for purposes of ERISA and Section
4975 of the Code to be assets of the investing Plan in certain circumstances
unless certain exceptions apply.

      Under the Plan Asset Regulation, the term "equity" interest is defined as
any interest in an entity other than an instrument that is treated as
indebtedness under "applicable local law" and which has no "substantial equity
features." If the securities of a series consist of notes or bonds that are not
treated as equity interests in the issuing trust for purposes of the Plan Asset
Regulation, a Plan's investment in such notes or bonds would not cause the trust
assets to be deemed Plan assets. However, the depositor, the servicer, the
trustee and the underwriter may be the depositor of or investment advisor with
respect to one or more Plans. Because such parties may receive certain benefits
in connection with the sale of the notes or bonds, the purchase of notes or
bonds using Plan assets over which any such parties (or any affiliates thereof)
has investment authority might be deemed to be a violation of the prohibited
transaction rules of ERISA and the Code for which no exemption may be available.
Accordingly, notes or bonds may not be purchased using the assets of any Plan if
the depositor, the servicer, the trustee, the underwriter or any of their
affiliates (a) has investment or administrative discretion with respect to such
Plan assets; (b) has authority or responsibility to give, or regularly gives,
investment advice with respect to such Plan assets for a fee and pursuant to an
agreement of understanding that such advice (i) will serve as a primary basis
for investment decisions with respect to such Plan assets and (ii) will be based
on the particular investment needs for such Plan; or (c) is an employer
maintaining or contributing to such Plan.

      In addition, the issuing trust or an affiliate might be considered or
might become a Party in Interest with respect to a Plan. Also, any holder of
certificates issued by the trust, because of its activities or the activities of
its respective affiliates, may be deemed to be a Party in Interest with respect
to certain Plans, including but not limited to Plans depositored by such holder.
In either case, the acquisition or holding of notes by or on behalf of such a
Plan could be considered to give rise to a prohibited transaction within the
meaning of ERISA and the Code, unless it is subject to one or more exemptions
such as:

      -     Prohibited Transaction Class Exemption ("PTCE") 84-14, which
            exempts certain transactions effected on behalf of a Plan by a
            "qualified professional asset manager";

      -     PTCE 90-1, which exempts certain transactions involving insurance
            company pooled separate accounts;

      -     PTCE 91-38, which exempts certain transactions involving bank
            collective investment funds;

                                      105



      -     PTCE 95-60, which exempts certain transactions involving insurance
            company general accounts; or

      -     PTCE 96-23, which exempts certain transactions effected on behalf of
            a Plan by certain "in-house asset managers."

      The prospectus supplement for a series of securities may require that
Plans investment in notes or bonds represent that the relevant conditions for
exemptive relief under at least one of the foregoing exemptions have been
satisfied.

      The Plan Asset Regulation provides that, generally, the assets of an
entity in which a Plan invests will not be deemed for purposes of ERISA to be
assets of such Plan if the equity interest acquired by the investing Plan is a
publicly-offered security, or if equity participation by benefit plan investors
is not significant. In general, a publicly-offered security, as defined in the
Plan Asset Regulation, is a security that is widely held, freely transferable
and registered under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). Equity participation in an entity by benefit plan investors is
not significant if, after the most recent acquisition of an equity interest in
the entity, less than 25% of the value of each class of equity interest in the
entity is held by "benefit plan investors," which include benefit plans
described in ERISA or under Section 4975 of the Code, whether or not they are
subject to ERISA, as well as entities whose underlying assets include assets of
a Plan by reason of a Plan's investment in the entity.

      If no exception under the Plan Asset Regulation applies and if a Plan (or
a person investing Plan assets, such as an insurance company general account)
acquires an equity interest in a trust established for a series of securities,
then the trust assets would be considered to be assets of the Plan. Because the
loans held by the trust may be deemed Plan assets of each Plan that purchases
equity securities, an investment in the securities by a Plan might be a
prohibited transaction under Sections 406 and 407 of ERISA and subject to an
excise tax under Section 4975 of the Code and may cause transactions undertaken
in the course of operating the trust to constitute prohibited transactions,
unless a statutory or administrative exemption applies.

      The DOL has issued PTCE 83-1, which exempts from ERISA's prohibited
transaction rules certain transactions relating to the operation of residential
mortgage pool investment trusts and the purchase, sale and holding of "mortgage
pool pass-through certificates" in the initial issuance of such certificates. If
the general conditions (discussed below) of PTEC 83-1 are satisfied, investments
by a Plan in certificates that provide for pass-through payments of principal
and interest and represent beneficial undivided fractional interests in a fixed
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 ("single
family securities") will be exempt from the prohibitions of Sections 406(a) and
407 of ERISA (relating generally to transactions with Parties in Interest who
are not fiduciaries) if the Plan purchases the single family securities at no
more than fair market value and will be exempt from the prohibitions of ERISA
Sections 406(b)(1) and (2) (relating generally to transactions with fiduciaries)
if, in addition, the purchase is approved by an independent fiduciary, no sales
commission is paid to the pool depositor,

                                      106



the Plan does not purchase more than 25% of all single family securities, and at
least 50% of all single family securities are purchased by persons independent
of the pool depositor or pool trustee. PTCE 83-1 does not provide an exemption
for transactions involving subordinate securities.

      The discussion in this and the next succeeding paragraph applies only to
single family securities. PTCE 83-1 sets forth three general conditions which
must be satisfied for any transaction to be eligible for exemption:

      -     the maintenance of a system of insurance or other protection for the
            pooled mortgage loans and property securing such loans, and for
            indemnifying certificate-holders against reductions in pass-through
            payments due to property damage or defaults in loan payments in an
            amount not less than the greater of one percent of the aggregate
            principal balance of all covered pooled mortgage loans or the
            principal balance of the largest covered pooled mortgage loan;

      -     the existence of a pool trustee who is not an affiliate of the pool
            depositor; and

      -     a limitation on the amount of the payment retained by the pool
            depositor, together with other funds inuring to its benefit, to not
            more than adequate consideration for selling the mortgage loans plus
            reasonable compensation for services provided by the pool depositor
            to the pool.

      The depositor believes that the first general condition referred to above
will be satisfied with respect to the certificates issued without a
subordination feature, or the senior certificates only in a series issued with a
subordination feature, provided that the subordination and reserve account,
subordination by shifting of interests, the pool insurance or other form of
credit enhancement described under "Credit Enhancement" in this prospectus
(such subordination, pool insurance or other form of credit enhancement being
the system of insurance or other protection referred to above) with respect to a
series of certificates is maintained in an amount not less than the greater of
one percent of the aggregate principal balance of the loans or the principal
balance of the largest loan. See "Description of the Securities" in this
prospectus. In the absence of a ruling that the system of insurance or other
protection with respect to a series of certificates satisfies the first general
condition referred to above, there can be no assurance that these features will
be so viewed by the DOL. The trustee will not be affiliated with the depositor.

      Each Plan Fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold single family securities
must make its own determination as to whether the first and third general
conditions, and the specific conditions described briefly in the preceding
paragraphs, of PTCE 83-1 have been satisfied, or as to the availability of any
other prohibited transaction exemptions. Each Plan fiduciary should also
determine whether, under the general fiduciary standards of investment prudence
and diversification, an investment in the certificates is appropriate for the
Plan, taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.

                                      107



      The DOL has issued to various underwriters individual prohibited
transaction exemptions which generally exempt from the application of certain
prohibited transaction provisions of ERISA and the Code transactions with
respect to the initial purchase, the holding and the subsequent resale by Plans
of securities issued by the investment pools whose assets consist of:

      -     certain types of secured receivables, secured loans and other
            secured obligations, including home equity loans, obligations
            secured by shares issued by a cooperative housing association, and
            obligations that bear interest or are purchased at a discount and
            which are secured by single-family residential real property and/or
            multi-family residential real property (including obligations
            secured by leasehold interests on residential real property);

      -     property securing a permitted obligation;

      -     undistributed cash, cash credited to a "pre-funding account" or a
            "capitalized interest account", and certain temporary investments
            made therewith; and

      -     certain types of credit support arrangements, including yield
            supplement agreements and interest-rate swaps that meet certain
            requirements set forth in exemptions.

The securities covered by the underwriter exemptions include certificates
representing a beneficial ownership interest in the assets of a trust (including
a grantor trust, owner trust or REMIC) and which entitle the holder to payments
of principal, interest and/or other payments made with respect to the assets of
such trust.

      Among the conditions that must be satisfied for the underwriter exemptions
to apply are the following:

      -     the plan must acquire the securities on terms, including the
            security price, that are at least as favorable to the plan as they
            would be in an arm's-length transaction with an unrelated party;

      -     the securities must not be subordinated to any other class of
            securities issued by the same issuer, unless the securities are
            issued in a "designated transaction";

      -     at the time of acquisition, the securities acquired by the plan must
            have received a rating in one of the three (or, in the case of
            designated transactions, four) highest generic rating categories
            from Standard and Poor's Rating Services, Moody's Investors Service,
            Inc. or Fitch Ratings, each referred to herein as a "rating
            agency";

      -     the trustee must not be an affiliate of any other member of the
            "restricted group ";

      -     the sum of all payments made to and retained by the underwriter must
            not total more than reasonable compensation for underwriting the
            securities, the sum of all payments made to and retained by the
            issuer's depositor for assigning the obligations to the issuer must
            not total more than the fair market value of the obligations, and
            the sum of all payments made to and retained by any servicer

                                      108



            must not total more than reasonable compensation and expense
            reimbursement for its services;

      -     the plan must be an "accredited investor" as defined in Rule
            501(a)(1) of Regulation D of the commission under the Securities Act
            of 1933; and

      -     in the event that all of the obligations used to fund the issuer
            have not been transferred to the issuer on the closing date,
            additional obligations having an aggregate value equal to no more
            than 25% of the total principal amount of the securities being
            offered may be transferred to the issuer under a pre-funding feature
            within ninety days or three months following the closing date.

      The issuer must also meet the following requirements:

      -     the assets of the issuer must consist solely of assets of the type
            that have been included in other investment pools;

      -     securities evidencing interests in other investment pools must have
            been rated in one of the three (or in the case of designated
            transactions, four) highest rating categories by a rating agency for
            at least one year prior to the plan's acquisition of securities; and

      -     investors other than plans must have purchased securities evidencing
            interests in the other investment pools for at least one year prior
            to the plan's acquisition of securities.

      For purposes of the underwriter exemptions, the term "designated
transaction" includes any securitization transaction in which the assets of the
issuer consist solely of home equity loans, obligations secured by shares issued
by a cooperative housing association and/or obligations that bear interest or
are purchased at a discount and which are secured by single-family residential
real property and/or multi-family residential real property (including
obligations secured by leasehold interests on residential real property). Such
home equity loans and residential mortgage loans may be less than fully secured,
provided that:

      -     the securities acquired by a plan in the designated transaction are
            not subordinated to any other class of securities issued by the same
            issuer;

      -     at the time of acquisition, the securities acquired by the plan must
            have received a rating in one of the two highest generic rating
            categories from a rating agency; and

      -     the obligations must be secured by collateral whose fair market
            value on the closing date of the designated transaction is at least
            equal to 80% of the sum of (i) the outstanding principal balance due
            under the obligation and (ii) the outstanding principal balance of
            any other obligations of higher priority (whether or not held by the
            issuer) which are secured by the same collateral.

      The underwriter exemptions also provide relief from various
self-dealing/conflict of interest prohibited transactions that may occur when a
plan fiduciary causes a plan to acquire securities of an issuer and the
fiduciary, or its affiliate, is an obligor with respect

                                      109



to obligations or receivables contained in the issuer; provided that, among
other requirements:

      -     in the case of an acquisition in connection with the initial
            issuance of the securities, at least fifty percent of each class of
            securities in which plans have invested is acquired by persons
            independent of the restricted group and at least fifty percent of
            the aggregate interest in the issuer is acquired by persons
            independent of the restricted group;

      -     the fiduciary, or its affiliate, is an obligor with respect to five
            percent or less of the fair market value of the obligations or
            receivables contained in the issuer;

      -     the plan's investment in each class of securities does not exceed
            twenty-five percent of all of the securities of that class
            outstanding at the time of acquisition; and

      -     immediately after the plan acquires the securities, no more than
            twenty-five percent of the plan's assets for which the person is a
            fiduciary are invested in certificates representing an interest in
            one or more trusts containing assets sold or serviced by the same
            entity.

      The underwriter exemptions do not apply to plans depositored by a member
of the restricted group, which includes the depositor, the servicer (and any
subservicer), the trustee, the underwriter, any obligor with respect to
obligations or receivables included in the issuer constituting more than five
percent of the aggregate unamortized principal balance of the issuer's assets,
any insurer, the counterparty to any interest-rate swap entered into by the
issuer and any affiliate of these parties.

      Prohibited transaction exemption 2000-58 amended the underwriter
exemptions and extended the relief available thereunder to transactions
involving the initial purchase, the holding and the subsequent resale by plans
of securities denominated as debt that are issued by, and are obligations of,
investment pools whose assets are held in trust. The same conditions described
above relating to certificates must also be met with respect to notes. In
addition, prior to the issuance of the notes, the issuer must receive a legal
opinion to the effect that the note holders will have a perfected security
interest in the issuer's assets. As with certificates, exemptive relief would
not be available for plans depositored by a member of the restricted group.

      The prospectus supplement will provide further information that plans
should consider before purchasing the securities. Any plan fiduciary that
proposes to cause a plan to purchase securities is encouraged to consult with
its counsel concerning the impact of ERISA and the Code, the applicability of
PTE 83-1, the availability and applicability of any underwriter exemption or any
other exemptions from the prohibited transaction provisions of ERISA and the
Code and the potential consequences in their specific circumstances, before
making the investment. Moreover, each plan fiduciary should determine whether
under the general fiduciary standards of investment prudence and diversification
an investment in the securities is appropriate for the plan, taking into account
the overall investment policy of the plan and composition of the plan's
investment portfolio.

                                      110



                                LEGAL INVESTMENT

      The prospectus supplement for each series of securities will specify
which, if any, of the classes of securities offered thereby constitute
"mortgage related securities" for purposes of the Secondary Mortgage Market
Enhancement Act of 1984 ("SMMEA"). Classes of securities that qualify as
mortgage related securities 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 (including the District of Columbia and Puerto Rico) whose authorized
investments are subject to state regulations to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any such entities. Under SMMEA, if a state enacted
legislation prior to October 4, 1991 specifically limiting the legal investment
authority of any of these entities with respect to mortgage related securities,
securities will constitute legal investments for entities subject to such
legislation only to the extent provided therein. Approximately twenty-one states
adopted such legislation prior to the October 4, 1991 deadline. SMMEA provides,
however, that in no event will the enactment of this type of legislation affect
the validity of any contractual commitment to purchase, hold or invest in
securities, or require the sale or other disposition of securities, so long as
such contractually commitment was made or such securities were 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 in securities
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase 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
authority may prescribe. In this connection, federal credit unions should review
the National Credit Union Administration ("NCUA") Letter to Credit Unions No.
96, as modified by NCUA Letter to Credit Unions No. 108, which includes
guidelines to assist federal credit unions in making investment decisions for
mortgage related securities and the NCUA's regulation "Investment and Deposit
Activities" (12C.F.R. Part 703), which sets forth certain restrictions on
investments by federal credit unions in mortgage related securities (in each
case whether or not the class of securities under consideration for purchase
constituted a mortgage related security).

      All depository institutions considering an investment in the securities
(whether or not the class of securities under consideration for purchase
constitutes a mortgage related security) should review the Federal Financial
Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
setting forth, in relevant part, certain securities trading and sales practices
deemed unsuitable for an institution's investment portfolio, and guidelines for
(and restrictions on) investing in mortgage derivative products, including
mortgage related securities which are "high-risk mortgage securities" as
defined in the Policy Statement. According to the Policy Statement, high-risk
mortgage securities include

                                      111



securities not entitled to distributions allocated to principal or interest and
subordinate securities. Under the Policy Statement, it is the responsibility of
each depository institution to determine, prior to purchase (and at stated
intervals thereafter), whether a particular mortgage derivative product is a
high-risk mortgage security, and whether the purchase (or retention) of such a
product would be consistent with the Policy Statement.

      The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders, guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to, "prudent investor" provisions which may restrict or prohibit investment in
securities which are not "interest bearing" or "income paying."

      There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase securities or to purchase
securities representing more than a specified percentage of the investor's
assets. Investors should consult their own legal advisors in determining whether
and to what extent the securities constitute legal investments for them.

                             METHOD OF DISTRIBUTION

      The securities are being offered hereby in series from time to time (each
series evidencing or relating to a separate trust) through any of the following
methods:

      -     by negotiated firm commitment underwriting and public reoffering by
            underwriters;

      -     by agency placements through one or more placement agents primarily
            with institutional investors and dealers; and

      -     by placement directly by the depositor with institutional investors.

      A prospectus supplement will be prepared for each series which will
describe the method of offering being used for that series and will set forth:

      -     the identity of any underwriters thereof;

      -     either the price at which such series is being offered, the nature
            and amount of any underwriting discounts or additional compensation
            to the underwriters and the proceeds of the offering to the
            depositor or the method by which the price at which the underwriters
            will sell the securities will be determined;

      -     information regarding the nature of the underwriters' obligations;

      -     any material relationship between the depositor and any underwriter;
            and

      -     where appropriate, information regarding any discounts or
            concessions to be allowed or reallowed to dealers or others and any
            arrangements to stabilize the market for the securities so offered.

      In firm commitment underwritten offerings, the underwriters will be
obligated to purchase all of the securities of the related series if any of
those securities are purchased.

                                      112



Securities may be acquired by the underwriters for their own accounts and may be
resold from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale.

      Underwriters and agents may be entitled under agreements entered into with
the depositor to indemnification by the depositor against certain civil
liabilities, including liabilities under the securities Act of 1933, as amended,
or to contribution with respect to payments which such underwriters or agents
may be required to make in respect thereof.

      Redwood Trust, Inc. or other affiliates of the depositor may purchase
securities and pledge them to secure indebtedness or, together with its
pledgees, donees, transferees or other successors in interest, sell the
securities, from time to time, either directly or indirectly through one or more
underwriters, underwriting syndicates or designated agents.

      If a series is offered other than through underwriters, the prospectus
supplement relating to that series will contain information regarding the nature
of the offering and any agreements to be entered into between the depositor and
purchasers of securities of that series.

                                  LEGAL MATTERS

      The validity of the securities will be passed upon for the depositor by
Tobin & Tobin, a professional corporation, San Francisco, California. Certain
federal income tax consequences with respect to the securities will be passed
upon for the depositor by Chapman and Cutler LLP, San Francisco, California.

                              FINANCIAL INFORMATION

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

                              AVAILABLE INFORMATION

      The depositor has filed with the SEC a registration statement under the
Securities Act of 1933, as amended, with respect to the securities. This
prospectus, which forms a part of the registration statement, and the supplement
relating to each series of securities contain information set forth in the
registration statement pursuant to the rules and regulations of the SEC. For
further information, reference is made to such registration statement and the
exhibits thereto, which may be inspected and copied at the facilities maintained

                 INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

      The SEC allows us to incorporate by reference some of the information
filed with it, which means that important information can be disclosed by
referring to those documents. Any statement contained in a document incorporated
or deemed to be incorporated by reference in this prospectus shall be deemed to
be modified or superseded for all purposes of this prospectus to the extent that
a statement contained in this prospectus (or in the accompanying supplement) or
in any other subsequently filed document which also is or is deemed to be
incorporated by reference modifies or replaces such statement. Any such
statement so modified or superseded shall not be deemed, except as modified or
superseded, to constitute a part of this prospectus. Neither the depositor nor
the servicer for any series intends to file with the SEC periodic reports with
respect to the related trust following completion of the reporting period
required by Rule 15d-1 or Regulation 15D under the Exchange Act.

      All documents filed by or on behalf of the trust referred to in the
accompanying prospectus supplement with the SEC pursuant to Section 13(a),
13(c), 14 or 15(d) of the Exchange Act on or after the date of that prospectus
supplement and prior to the termination of any offering of the securities issued
by the trust shall be deemed to be incorporated by reference in this prospectus
and to be a part of this prospectus from the date of the filing of those
documents.

      The trust will provide without charge to each person to whom this
prospectus is delivered, on the written or oral request of such person, a copy
of any or all of the documents referred to above that have been or may be
incorporated by reference in this prospectus (not including exhibits to the
information that is incorporated by reference unless such exhibits are
specifically incorporated by reference into the information that this prospectus
incorporates). Requests for these documents should be directed to the corporate
trust office of the trustee specified in the accompanying prospectus supplement.

                                     RATING

      It is a condition to the issuance of the securities of each series offered
hereby and by the supplement that they shall be rated in one of the four highest
rating categories by the nationally recognized statistical rating agency or
agencies specified in the prospectus supplement.

      Ratings on asset-backed securities address the likelihood of receipt by
security holders of all distributions on the trust assets. These ratings address
the structural, legal and issuer-related aspects associated with such
securities, the nature of the trust assets and the credit quality of the credit
enhancer or guarantor, if any. Ratings on asset-backed securities do not
represent any assessment of the likelihood of principal

                                      114



prepayments by mortgagors or of the degree by which actual prepayments might
differ from those originally anticipated. As a result, securityholders might
suffer a lower than anticipated yield, and, in addition, holders of stripped
securities in extreme cases might fail to recoup their underlying 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. Further, security ratings do not address the effect of prepayments
on the yield anticipated by the investor. Each security rating should be
evaluated independently of any other security rating.
