                                MASTER SERVICER
 
     This Prospectus describes certain Mortgage Loan Asset-Backed Securities
(the 'Securities') that may be issued from time to time in series and certain
classes of which may be offered hereby from time to time as described in the
related Prospectus Supplement. Each series of Securities will be issued by a
separate trust (each, a 'Trust'). The primary assets of each Trust will consist
of a segregated pool (a 'Mortgage Pool') of conventional one- to four-family
residential mortgage loans, multi-family residential mortgage loans, mixed use
mortgage loans, revolving home equity loans or certain balances thereof secured
by mortgages primarily on one-to-four-family residential properties, or
certificates of interest or participation therein (collectively, the 'Mortgage
Loans'), to be acquired by such Trust from Advanta Mortgage Conduit Services,
Inc. (the 'Sponsor'). The Sponsor will acquire the Mortgage Loans from one or
more affiliated or unaffiliated institutions (the 'Originators'). In connection
with the establishment of certain Trusts the Sponsor may first transfer the
related Trust Estate to Advanta Mortgage Receivables Inc. (the 'Transferor') and
the Transferor will then transfer such Trust Estate to the related Trust. The
use of the Transferor will not affect the obligations of the Sponsor with
respect to the related Trust or the related Securities. If the Transferor is to
be involved in a particular offering the related Prospectus Supplement will
describe its role in such offering; for purposes of this Prospectus the role of
the Transferor is subsumed in the role of the Sponsor. See 'The Mortgage Pools.'
 
     The Mortgage Loans in each Mortgage Pool and certain other assets described
herein and in the related Prospectus Supplement (collectively with respect to
each Trust, the 'Trust Estate') and in the related Prospectus Supplement will be
held by the related Trust for the benefit of the holders of the related series
of Securities (the 'Securityholders') pursuant to a Pooling and Servicing
Agreement to the extent and as more fully described herein and in the related
Prospectus Supplement. Unless otherwise specified in the related Prospectus
Supplement, each Mortgage Pool will consist of one or more of the various types
of Mortgage Loans described under 'The Mortgage Pools.'

THE ASSETS OF THE RELATED TRUST ARE THE SOLE SOURCE OF PAYMENTS ON THE RELATED
SECURITIES. THE SECURITIES DO NOT REPRESENT AN INTEREST IN OR OBLIGATION OF THE
SPONSOR, THE MASTER SERVICER, ANY ORIGINATOR OR ANY OF THEIR AFFILIATES, EXCEPT
AS SET FORTH HEREIN AND IN THE RELATED PROSPECTUS SUPPLEMENT. NEITHER THE
SECURITIES NOR THE UNDERLYING MORTGAGE LOANS WILL BE GUARANTEED OR INSURED BY
ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY OR BY THE SPONSOR, THE MASTER
SERVICER, ANY ORIGINATOR OR ANY OF THEIR AFFILIATES, EXCEPT AS SET FORTH IN THE
RELATED PROSPECTUS SUPPLEMENT. SEE ALSO 'RISK FACTORS' PAGE 13.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
      ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE

of Distribution' and in the related Prospectus Supplement. There will be no

develop or, if it does develop, that it will offer sufficient liquidity of
investment or will continue.

(Cover continued from previous page)
 
     Each series of Securities will include one or more classes. The Securities
of any particular class may represent beneficial ownership interests in the
related Mortgage Loans held by the related Trust, or may represent debt secured
by such Mortgage Loans, as described herein and in the related Prospectus
Supplement. A series may include one or more classes of Securities entitled to
principal distributions, with disproportionate, nominal or no interest
distributions, or to interest distributions, with disproportionate, nominal or
no principal distributions. The rights of one or more classes of Securities of
any series may be senior or subordinate to the rights of one or more of the
other classes of Securities. A series may include two or more classes of
Securities which differ as to the timing, sequential order, priority of payment,
interest rate or amount of distributions of principal or interest or both.
Information regarding each class of Securities of a series, and certain
characteristics of the Mortgage Loans to be evidenced by such Securities, will
be set forth in the related Prospectus Supplement.
 
     THE SPONSOR'S AND THE RELATED ORIGINATORS' ONLY OBLIGATIONS WITH RESPECT TO
A SERIES OF SECURITIES WILL BE PURSUANT TO THE SERVICING REQUIREMENTS RELATING
THERETO, AND PURSUANT TO CERTAIN REPRESENTATIONS AND WARRANTIES MADE BY THE
SPONSOR OR BY SUCH ORIGINATORS, EXCEPT AS OTHERWISE DESCRIBED IN THE RELATED
PROSPECTUS SUPPLEMENT. THE PROSPECTUS SUPPLEMENT FOR EACH SERIES OF SECURITIES
WILL NAME ADVANTA MORTGAGE CORP. USA AS MASTER SERVICER (THE 'MASTER SERVICER')
WHICH WILL ACT, DIRECTLY OR THROUGH ONE OR MORE SUBSERVICERS (THE
'SUBSERVICER(S)'). THE PRINCIPAL OBLIGATIONS OF THE MASTER SERVICER WILL BE
PURSUANT TO ITS CONTRACTUAL SERVICING OBLIGATIONS (WHICH MAY INCLUDE A LIMITED
OBLIGATION TO MAKE CERTAIN ADVANCES IN THE EVENT OF DELINQUENCIES IN PAYMENTS ON
THE MORTGAGE LOANS AND INTEREST SHORTFALLS DUE TO PREPAYMENT OF MORTGAGE LOANS).
SEE 'DESCRIPTION OF THE SECURITIES.'
 
     If so specified in the related Prospectus Supplement, the Trust Estate for
a series of Securities may include any combination of a mortgage pool insurance
policy, letter of credit, financial guaranty insurance policy, bankruptcy bond,
special hazard insurance policy, reserve fund or other form of Credit
Enhancement. In addition to or in lieu of the foregoing, Credit Enhancement with
respect to certain classes of Securities of any series may be provided by means
of subordination, cross-support among Mortgage Assets, as defined herein, or
over-collateralization. See 'Description of Credit Enhancement.'
 
     The rate of payment of principal of each class of Securities entitled to
principal payments will depend on the priority of payment of such class and the
rate of payment (including prepayments, defaults, liquidations and repurchases
of Mortgage Loans) of the related Mortgage Loans. A rate of principal payment
lower or higher than that anticipated may affect the yield on each class of
Securities in the manner described herein and in the related Prospectus
Supplement. The various types of Securities, the different classes of such
Securities and certain types of Mortgage Loans in a given Mortgage Pool may have
different prepayment risks and credit risks. The Prospectus Supplement for a
series of Securities or the related Current Report on Form 8-K will contain
information as to (i) types, maturities and certain statistical information

relating to credit risks of the Mortgage Loans in the related Mortgage Pool,
(ii) the effect of certain rates of prepayment, based upon certain specified
assumptions for a series of Securities and (iii) priority of payment and
maturity dates of the Securities. AN INVESTOR SHOULD CAREFULLY REVIEW THE
INFORMATION IN THE RELATED PROSPECTUS SUPPLEMENT CONCERNING THE DIFFERENT
CONSEQUENCES OF THE RISKS ASSOCIATED WITH THE DIFFERENT TYPES AND CLASSES OF
SECURITIES. See 'Yield Considerations.' A Trust may be subject to early
termination under the circumstances described herein and in the related
Prospectus Supplement.
 
     One or more separate elections may be made to treat a Trust, or one or more
segregated pools of assets held by such Trust, as a real estate mortgage
investment conduit ('REMIC') for federal income tax purposes. If applicable, the
Prospectus Supplement for a series of Securities will specify which class or
classes of the related series of Securities will be considered to be regular
interests in a REMIC and which classes of Securities or other interests will be
designated as the residual interest in a REMIC. Alternatively, a Trust may be
treated as a grantor trust or as a partnership for federal income tax purposes,
or may be treated for federal income tax purposes as a mere security device
which constitutes a collateral arrangement for the issuance of secured debt. See
'Certain Federal Income Tax Consequences' herein.

                         one or more institutions affiliated with the
                         Sponsor ('Affiliated Originators') or
                         institutions unaffiliated with the Sponsor
                         ('Unaffiliated Originators') (the Affiliated
                         Originators and the Unaffiliated Originators are
                         collectively referred to as the 'Originators').
                         The Sponsor will transfer the related Trust

                         the establishment of certain Trusts the Sponsor
                         may first transfer the related Trust Estate to

                         The use of the Transferor will not affect the
                         obligations of the Sponsor with respect to the
                         related Trust or the related Securities. If the
                         Transferor is to be involved in a particular

                         of this Prospectus the role of the Transferor is
                         subsumed in the role of the Sponsor.

                         to such Mortgage Loans have been transferred to
                         the Master Servicer or to a third-party,

The Securities......   Issuance of Securities.
                       Each series of Securities will be issued at the
                         direction of the Sponsor by a separate Trust
                         (each, a 'Trust'). The primary assets of each
                         Trust will consist of a segregated pool (each, a
                         'Mortgage Pool') of conventional, one- to
                         four-family residential mortgage loans or

                         participation therein, acquired by such Trust
                         from the Sponsor. The Sponsor will acquire the
                         Mortgage Loans from one or more of the
                         Originators. The Securities issued by any Trust
                         may represent beneficial ownership interests in
                         the related Mortgage Loans held by the related
                         Trust, or may represent debt secured by such
                         Mortgage Loans, as described herein and in the
                         related Prospectus Supplement. Securities which
                         represent beneficial ownership interests in the
                         related

 
                                       4

 

                    
                         Trust will be referred to as 'Certificates' in
                         the related Prospectus Supplement; Securities
                         which represent debt issued by the related Trust
                         will be referred to as 'Notes' in the related
                         Prospectus Supplement.
                       Each Trust will be established pursuant to an
                         agreement (each, a 'Trust Agreement') by and
                         between the Sponsor and the Trustee named
                         therein. Each Trust Agreement will describe the
                         related pool of assets to be held in trust (each
                         such asset pool, the 'Trust Estate'), which will
                         include the related Mortgage Loans and, if so
                         specified in the related Prospectus Supplement,
                         may include any combination of a mortgage pool
                         insurance policy, letter of credit, financial
                         guaranty insurance policy, special hazard
                         policy, reserve fund or other form of Credit
                         Enhancement.
                       The Mortgage Loans held by each Trust will be
                         master serviced by the Master Servicer pursuant
                         to a servicing agreement (each, a 'Servicing
                         Agreement') by and between the Master Servicer
                         and the related Trustee.
                       With respect to Securities that represent debt
                         issued by the related Trust, the related Trust
                         will enter into an indenture (each, an

                         'Indenture') by and between such Trust and the
                         trustee named on such Indenture (the 'Indenture
                         Trustee'), as set forth in the related
                         Prospectus Supplement. Securities that represent
                         beneficial ownership interests in the related
                         Trust will be issued pursuant to the related
                         Trust Agreement.
                       In the case of any individual Trust, the
                         contractual arrangements relating to the
                         establishment of the Trust, the servicing of the
                         related Mortgage Loans and the issuance of the
                         related Securities may be contained in a single
                         agreement, or in several agreements which
                         combine certain aspects of the Trust Agreement,
                         the Servicing Agreement and the Indenture
                         described above (for example, a pooling and
                         servicing agreement, or a servicing and
                         collateral management agreement). For purposes
                         of this Prospectus, the term 'Pooling and
                         Servicing Agreement' as used with respect to a
                         Trust means, collectively, and except as
                         otherwise specified, any and all agreements
                         relating to the establishment of the related
                         Trust, the servicing of the related Mortgage
                         Loans and the issuance of the related
                         Securities.
                       Securities Will Be Recourse to the Assets of the
                         Related Trust Only.
                       The sole source of payment for any series of
                         Securities will be the assets of the related
                         Trust (i.e., the related Trust Estate). The
                         Securities will not be obligations, either
                         recourse or non-recourse (except for certain
                         non-recourse debt described under 'Certain
                         Federal Income Tax Consequences'), of the
                         Sponsor, the Master Servicer, any Sub-Servicer,
                         any Originator or any Person other than the
                         related Trust. In the case of Securities that
                         represent beneficial ownership interest in the
                         related Trust Estate, such Securities will
                         represent the ownership of such Trust Estate;
                         with respect to Securities that represent debt
                         issued by the related Trust, such Securities
                         will be secured by the related Trust Estate.
                         Notwithstanding the foregoing, and as to be
                         described in the related Prospectus Supplement,
                         certain types of Credit Enhancement, such as a
                         financial guaranty insurance policy or a letter
                         of

 
                                       5

 


                    
                         credit, may constitute a full recourse
                         obligation of the issuer of such Credit
                         Enhancement.
                       General Nature of the Securities as Investments.
                       The Securities will consist of two basic types:
                         (i) Securities of the fixed-income type
                         ('Fixed-Income Securities') and (ii) Securities
                         of the equity participation type ('Equity
                         Securities'). No Class of Equity Securities will
                         be offered pursuant to this Prospectus or any
                         Prospectus Supplement related hereto.
                         Fixed-Income Securities will generally be styled
                         as debt instruments, having a principal balance
                         and a specified interest rate ('Interest Rate').
                         Fixed-Income Securities may be either benefi-
                         cial ownership interests in the related Mortgage
                         Loans held by the related Trust, or may
                         represent debt secured by such Mortgage Loans.
                         Each series or class of Fixed-Income Securities
                         may have a different Interest Rate, which may be
                         a fixed or adjustable Interest Rate. The related
                         Prospectus Supplement will specify the Interest
                         Rate for each series or class of Fixed-Income
                         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 of
                         Fixed-Income Securities ('Strip Securities')
                         entitled (i) to principal distributions, with
                         disproportionate, nominal or no interest
                         distributions, or (ii) to interest
                         distributions, with disproportionate, nominal or
                         no principal distributions. In addition, a
                         series may include two or more classes of
                         Fixed-Income Securities that differ as to
                         timing, sequential order, priority of payment,
                         Interest Rate or amount of distributions of
                         principal or interest or both, or as to which
                         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 Mortgage
                         Pool, which series may include one or more
                         classes of Fixed-Income Securities ('Accrual
                         Securities'), as to which certain accrued
                         interest will not be distributed but rather will
                         be added to the principal balance (or nominal
                         principal balance, in the case of Accrual
                         Securities which are also Strip Securities)
                         thereof on each Payment Date, as hereinafter
                         defined and in the manner described in the

                         related Prospectus Supplement.
                       If so provided in the related Prospectus
                         Supplement, a series of Securities may include
                         one or more other classes of Fixed-Income
                         Securities (collectively, the 'Senior
                         Securities') that are senior to one or more
                         other classes of Fixed-Income Securities
                         (collectively, the 'Subordinate Securities') in
                         respect of certain distributions of principal
                         and interest and allocations of losses on
                         Mortgage Loans.
                       In addition, certain classes of Senior (or
                         Subordinate) Securities may be senior to other
                         classes of Senior (or Subordinate) Securities in
                         respect of such distributions or losses.
                       Equity Securities will represent the right to
                         receive the proceeds of the related Trust Estate
                         after all required payments have been made to
                         the Securityholders of the related Fixed-Income
                         Securities (both Senior Securities and
                         Subordinate Securities), and following any
                         required deposits to any reserve account which
                         may

 
                                       6

 

                    
                         be established for the benefit of the
                         Fixed-Income Securities. Equity Securities may
                         constitute what are commonly referred to as the
                         'residual interest,' 'seller's interest' or the
                         'general partnership interest,' depending upon
                         the treatment of the related Trust for federal
                         income tax purposes. As distinguished from the
                         Fixed-Income Securities, the Equity Securities
                         will not be styled as having principal and
                         interest components. Any losses suffered by the
                         related Trust will first be absorbed by the
                         related class of Equity Securities, as described
                         herein and in the related Prospectus Supplement.
                       No Class of Equity Securities will be offered
                         pursuant to this Prospectus or any Prospectus
                         Supplement related hereto. Equity Securities may
                         be offered on a private placement basis or
                         pursuant to a separate Registration Statement to
                         be filed by the Sponsor. In addition, the
                         Sponsor and its affiliates may initially or
                         permanently hold any Equity Securities issued by
                         any Trust.
                       General Payment Terms of Securities.
                       As provided in the related Pooling and Servicing

                         Agreement and as described in the related
                         Prospectus Supplement, Securityholders will be
                         entitled to receive payments on their Securities
                         on specified dates (each, a 'Payment Date').
                         Payment Dates with respect to Fixed-Income
                         Securities will occur monthly, quarterly or
                         semi-annually, as described in the related
                         Prospectus Supplement; Payment Dates with
                         respect to Equity Securities will occur as
                         described in the related Prospectus Supplement.
                       The related Prospectus Supplement will describe a
                         date (the 'Record Date') preceding such Payment
                         Date, as of which the Trustee or its paying
                         agent will fix the identity of the Securi-
                         tyholders for the purpose of receiving payments
                         on the next succeeding Payment Date. Unless
                         otherwise described in the related Prospectus
                         Supplement, the Payment Date will be the
                         twenty-fifth day of each month (or, in the case
                         of quarterly-pay Securities, the twenty-fifth
                         day of every third month; and in the case of
                         semi-annual pay Securities, the twenty-fifth day
                         of every sixth month) and the Record Date will
                         be the close of business as of the last day of
                         the calendar month that precedes the calendar
                         month in which such Payment Date occurs.
                       Each Pooling and Servicing Agreement will describe
                         a period (each, a 'Remittance Period')
                         antecedent to each Payment Date (for example, in
                         the case of monthly-pay Securities, the calendar
                         month preceding the month in which a Payment
                         Date occurs or such other specified period).
                         Unless otherwise provided in the related
                         Prospectus Supplement, collections received on
                         or with respect to the related Mortgage Loans
                         during a Remittance Period will be required to
                         be remitted by the Master Servicer to the
                         related Trustee prior to the related Payment
                         Date and will be used to fund payments to
                         Securityholders on such Payment Date. As may be
                         described in the related Prospectus Supplement,
                         the related Pooling and Servicing Agreement may
                         provide that all or a portion of the principal
                         collected on or with respect to the related
                         Mortgage Loans may be applied by the related
                         Trustee to the acquisition of additional
                         Mortgage Loans during a specified period (rather
                         than be used to fund payments of principal to

 
                                       7

 


                    
                         Securityholders during such period) with the
                         result that the related securities will possess
                         an interest-only period, also commonly referred
                         to as a revolving period, which will be followed
                         by an amortization period. Any such
                         interest-only or revolving period may, upon the
                         occurrence of certain events to be described in
                         the related Prospectus Supplement, terminate
                         prior to the end of the specified period and
                         result in the earlier than expected amortiza-
                         tion of the related Securities.
                       In addition, and as may be described in the
                         related Prospectus Supplement, the related
                         Pooling and Servicing Agreement may provide that
                         all or a portion of such collected principal may
                         be retained by the Trustee (and held in certain
                         temporary investments, including Mortgage Loans)
                         for a specified period prior to being used to
                         fund payments of principal to Securityholders.
                       The result of such retention and temporary
                         investment by the Trustee of such principal
                         would be to slow the amortization rate of the
                         related Securities relative to the amortization
                         rate of the related Mortgage Loans, or to
                         attempt to match the amortization rate of the
                         related Securities to an amortization schedule
                         established at the time such Securities are
                         issued. Any such feature applicable to any
                         Securities may terminate upon the occurrence of
                         events to be described in the related Prospectus
                         Supplement, resulting in the current
                         distribution of principal payments to the
                         specified Securityholders and an acceleration of
                         the amortization of such Securities.
                       Unless otherwise specified in the related
                         Prospectus Supplement, neither the Securities
                         nor the underlying Mortgage Loans will be
                         guaranteed or insured by any governmental agency
                         or instrumentality or the Sponsor, the Master
                         Servicer, any Sub-Servicer, any Originator or
                         any of their affiliates.
No Investment
  Companies.........   Neither the Sponsor nor any Trust will register as
                         an 'investment company' under the Investment
                         Company Act of 1940, as amended (the 'Investment
                         Company Act').
Cross-                   
  Collateralization... Unless otherwise provided in the related Pooling
                         and Servicing Agreement and described in the
                         related Prospectus Supplement, the source of
                         payment for Securities of each series will be
                         the assets of the related Trust Estate only.
                         However, as may be described in the related

                         Prospectus Supplement, a Trust Estate may
                         include the right to receive moneys from a
                         common pool of Credit Enhancement which may be
                         available for more than one series of
                         Securities, such as a master reserve account or
                         a master insurance policy. Notwithstanding the
                         foregoing, unless specifically described
                         otherwise in the related Prospectus Supplement,
                         no collections on any Mortgage Loans held by any
                         Trust may be applied to the payment of
                         Securities issued by any other Trust (except to
                         the limited extent that certain collections in
                         excess of amounts needed to pay the related
                         Securities may be deposited in a common, master
                         reserve account that provides Credit Enhance-
                         ment for more than one series of Securities).
The Mortgage
  Pools.............   Unless otherwise specified in the related
                         Prospectus Supplement, each Trust Estate will
                         consist primarily of Mortgage Loans secured by
                         liens on one- to four-family residential or
                         multi-family properties ('Mortgages'), located
                         in any one of the fifty states,

 
                                       8

 

                    
                         the District of Columbia, Puerto Rico or any
                         other Territories of the United States. All
                         Mortgage Loans will have been acquired by the
                         related Trust from the Sponsor. All Mortgage
                         Loans will have been originated either by (x)
                         one or more institutions affiliated with the
                         Sponsor (such affiliated institutions, the
                         'Affiliated Originators') or (y) one or more
                         institutions not affiliated with the Sponsor
                         (such unaffiliated institutions, the
                         'Unaffiliated Originators'). The Mortgage Loans
                         originated by the Affiliated Originators
                         generally will have been originated pursuant to
                         the standard underwriting guidelines (the
                         'Sponsor's Guidelines') set forth in the
                         Sponsor's guide for originators (the 'Sponsor's
                         Originator Guide'), as modified from time to
                         time. The Mortgage Loans originated by the
                         Unaffiliated Originators may be originated
                         either (i) generally pursuant to the Sponsor's
                         Guidelines; (ii) generally pursuant to such
                         Unaffiliated Originators' underwriting
                         guidelines as approved by the Sponsor ('Approved
                         Guidelines'); or (iii) generally pursuant to

                         such Originators' underwriting guidelines and
                         purchased by the Sponsor in a bulk acquisition
                         ('Bulk Acquisition'). See 'Mortgage Loan Pro-
                         gram.' For a description of the types of
                         Mortgage Loans that may be included in the
                         Mortgage Pools, see 'The Mortgage Pools-- The
                         Mortgage Loans.'
                       A Current Report on Form 8-K will be available to
                         purchasers or underwriters of the related series
                         of Securities and will generally be filed,
                         together with the related Pooling and Servicing
                         Agreement, with the Securities and Exchange
                         Commission within fifteen days after the initial
                         issuance of such series.
Forward Commitments;
  Pre-Funding.......   A Trust may enter into an agreement (each, a
                         'Forward Purchase Agreement') with the Sponsor
                         whereby the Sponsor will agree to transfer
                         additional Mortgage Loans (the 'Subsequent
                         Mortgage Loans') to such Trust following the
                         date on which such Trust is established and the
                         related Securities are issued. Any Forward
                         Purchase Agreement will require that any
                         Mortgage Loans so transferred to a Trust conform
                         to the requirements specified in such Forward
                         Purchase Agreement. In addition, the Forward
                         Purchase Agreement states that the Depositor
                         shall only transfer the Subsequent Mortgage
                         Loans upon the satisfaction of certain
                         conditions including that the Depositor shall
                         have delivered to the Certificate Insurer, the
                         Rating Agencies and the Trustee opinions of
                         counsel (including bankruptcy, corporate and tax
                         opinions) with respect to the transfer of the
                         Subsequent Mortgage Loans. If a Forward Purchase
                         Agreement is to be utilized, and unless other-
                         wise specified in the related Prospectus
                         Supplement, the related Trustee will be required
                         to deposit in a segregated account (each, a
                         'Pre-Funding Account') all or a portion of the
                         proceeds received by the Trustee in connection
                         with the sale of one or more classes of
                         Securities of the related series; subsequently,
                         the additional Mortgage Loans will be
                         transferred to the related Trust in exchange for
                         money released to the Sponsor from the related
                         Pre-Funding Account in one or more transfers.
                         Each Forward Purchase Agreement will set a
                         specified period during which any such transfers
                         must occur. The Forward Purchase Agreement or
                         the related Pooling and Servicing Agreement will
                         require that, if



                                       9


                    
                         all moneys originally deposited to such
                         Pre-Funding Account are not so used by the end
                         of such specified period, then any remaining
                         moneys will be applied as a mandatory prepayment
                         of the related class or classes of Securities as
                         specified in the related Prospectus Supplement.
Credit
  Enhancement.......   If so specified in the Prospectus Supplement, the
                         Trust Estate with respect to any series of
                         Securities may include any one or any
                         combination of a letter of credit, mortgage pool
                         insurance policy, special hazard insurance
                         policy, bankruptcy bond, financial guaranty
                         insurance policy, reserve fund or other type of
                         Credit Enhancement to provide full or partial
                         coverage for certain defaults and losses
                         relating to the Mortgage Loans. Credit support
                         also may be provided in the form of the related
                         class of Equity Securities, and/or by
                         subordination of one or more classes of
                         Fixed-Income Securities in a series under which
                         losses in excess of those absorbed by any
                         related class of Equity Securities are first
                         allocated to any Subordinate Securities up to a
                         specified limit, cross-support among groups of
                         Mortgage Assets or overcollateralization. Unless
                         otherwise specified in the related Prospectus
                         Supplement, any mortgage pool insurance policy
                         will have certain exclusions from coverage
                         thereunder, which will be described in the
                         related Prospectus Supplement, which may be
                         accompanied by one or more separate Credit
                         Enhancements that may be obtained to cover
                         certain of such exclusions. To the extent not
                         set forth herein, the amount and types of
                         coverage, the identification of any entity
                         providing the coverage, the terms of any
                         subordination and related information will be
                         set forth in the Prospectus Supplement relating
                         to a series of Securities. See 'Description of
                         Credit Enhancement' and 'Subordination.'
Advances............   As to be described in the related Prospectus
                         Supplement, the Master Servicer may be obligated
                         to make certain advances with respect to
                         payments of delinquent scheduled interest and/or
                         principal on the Mortgage Loans, but only to the
                         extent that the Master Servicer believes that
                         such amounts will be recoverable by it. Any such
                         advance made by the Master Servicer with respect
                         to a Mortgage Loan is recoverable by it as

                         provided herein under 'Description of the
                         Securities--Advances' either from recoveries on
                         the specific Mortgage Loan or, with respect to
                         any such advance subsequently determined to be
                         nonrecoverable, out of funds otherwise
                         distributable to the holders of the related
                         series of Securities, which may include the
                         holders of any Senior Securities of such series.
                       As to be described in the related Prospectus
                         Supplement, the Master Servicer may be required
                         to advance Compensating Interest as defined
                         hereafter under 'Description of the Securities--
                         Advances.'
                       In addition, unless otherwise specified in the
                         related Prospectus Supplement, the Master
                         Servicer will be required to pay all 'out of
                         pocket' costs and expenses incurred in the
                         performance of its servicing obligations, but
                         only to the extent that the Master Servicer
                         reasonably believes that such amounts will
                         increase Net Liquidation Proceeds on the related
                         Mortgage Loan. See 'Description of the
                         Securities--Advances.'

Legal Investment....   Not all of the Mortgage Loans in a particular
                         Mortgage Pool may represent first liens.
                         Accordingly, as disclosed in the related Pro-
                         spectus Supplement, certain classes of
                         Securities offered hereby and by the related
                         Prospectus Supplement may not constitute
                         'mortgage related securities' for purposes of
                         the Secondary Mortgage Market Enhancement Act of
                         1984 ('SMMEA') and, if so, will not be legal
                         investments for certain types of institutional
                         investors under SMMEA.
                       Institutions whose investment activities are
                         subject to legal investment laws and regulations
                         or to review by certain regulatory authorities
                         may be subject to additional restrictions on
                         investment in certain classes of Securities. Any
                         such institution should consult its own legal
                         advisors in determining whether and to what
                         extent a class of Securities constitutes legal
                         investments for such investors. See 'Legal
                         Investment' herein.
ERISA
  Considerations....   A fiduciary of an employee benefit plan and
                         certain other retirement plans and arrangements,

                         (each such entity, a 'Plan') should carefully
                         review with its legal advisors whether the
                         purchase or holding of Securities could give
                         rise to a transaction that is prohibited or is
                         not otherwise permissible either under ERISA or
                         Section 4975 of the Code. Investors are advised
                         to consult their counsel and to review 'ERISA
                         Considerations' herein.

                         or (iv) interests in a Trust which is treated as
                         a partnership ('Partnership Interests').
                       Investors are advised to consult their tax
                         advisors and to review 'Certain Federal Income
                         Tax Consequences' herein and in the related
                         Prospectus Supplement.
Registration of
  Securities........   Securities may be represented by global securities
                         registered in the name of Cede & Co. ('Cede'), as
                         nominee of The Depository Trust Company ('DTC'),
                         or another nominee. In such case,
                         Securityholders will not be entitled to receive
                         definitive securities representing such Holders'
                         interests, except in certain circumstances
                         described in the related Prospectus Supplement.
                         See 'Description of the Securities--Form of
                         Securities' herein.
Ratings.............   Each class of Fixed-Income Securities offered
                         pursuant to the related Prospectus Supplement will
                         be rated in one of the four highest rating
                         categories by one or more 'national statistical
                         rating organizations,' as defined in the
                         Securities Exchange Act of 1934, as amended (the
                         'Exchange Act'), and commonly referred to as
                         'Rating Agencies.' Such ratings will address, in
                         the opinion of such Rating Agencies, the
                         likelihood that the related Trust will be able
                         to make timely payment of all amounts due on the
                         related Fixed-Income Securities in accordance
                         with the terms thereof. Such ratings will
                         neither address any prepayment or yield
                         considerations applicable to any Securities nor
                         constitute a recommendation to buy, sell or hold
                         any Securities.
                       Equity Securities will not be rated.
                       The ratings expected to be received with respect
                         to any Securities will be set forth in the
                         related Prospectus Supplement.

 
                                       12




                                  RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with the purchase of the Securities.
 
     Limited Liquidity.  There can be no assurance that a secondary market for
the Securities of any series or class will develop or, if it does develop, that
it will provide Securityholders with liquidity of investment or that it will
continue for the life of the Securities of any series. The Prospectus Supplement
for any series of Securities may indicate that an underwriter specified therein
intends to establish a secondary market in such Securities; however, no
underwriter will be obligated to do so. Unless otherwise specified in the
related Prospectus Supplement, the Securities will not be listed on any
securities exchange.
 
     Limited Obligations.  The Securities will not represent an interest in or
obligation, either recourse or non-recourse (except for certain non-recourse
debt described under 'Certain Federal Income Tax Consequences'), of the Sponsor,
the Master Servicer, any Originator (as defined herein) or any person other than
the related Trust. The only obligations of the foregoing entities with respect
to the Securities or the Mortgage Loans will be the obligations (if any) of the
Sponsor, the related Originators and the Master Servicer pursuant to certain
limited representations and warranties made with respect to the Mortgage Loans,
the Master Servicer's servicing obligations under the related Pooling and
Servicing Agreement (including its limited obligation, if any, to make certain
advances in the event of delinquencies on the Mortgage Loans, but only to the
extent deemed recoverable) and, if and to the extent expressly described in the
related Prospectus Supplement, certain limited obligations of the Sponsor,
Master Servicer, applicable Sub-Servicer, or another party in connection with a
purchase obligation ('Purchase Obligation') or an agreement to purchase or act
as remarketing agent with respect to a Convertible Mortgage Loan upon conversion
to a fixed rate. Notwithstanding the foregoing, and as to be described in the
related Prospectus Supplement, certain types of Credit Enhancement, such as a
financial guaranty insurance policy or a letter of credit, may constitute a full
recourse obligation of the issuer of such Credit Enhancement. Except as
described in the related Prospectus Supplement, neither the Securities nor the
underlying Mortgage Loans will be guaranteed or insured by any governmental
agency or instrumentality, or by the Sponsor, the Master Servicer, any
Sub-Servicer or any of their affiliates. Proceeds of the assets included in the
related Trust Estate for each series of Securities (including the Mortgage Loans
and any form of Credit Enhancement) will be the sole source of payments on the
Securities, and there will be no recourse to the Sponsor or any other entity in
the event that such proceeds are insufficient or otherwise unavailable to make
all payments provided for under the Securities.
 
     Limitations, Reduction and Substitution of Credit Enhancement.  With
respect to each series of Securities, Credit Enhancement will be provided in
limited amounts to cover certain types of losses on the underlying Mortgage
Loans. Credit Enhancement will be provided in one or more of the forms referred
to herein, including, but not limited to: a letter of credit; a Purchase
Obligation; a mortgage pool insurance policy; a special hazard insurance policy;
a bankruptcy bond; a reserve fund; a financial guaranty insurance policy or

other type of Credit Enhancement to provide partial coverage for certain
defaults and losses relating to the Mortgage Loans. Credit Enhancement also may
be provided in the form of the related class of Equity Securities, subordination
of one or more classes of Fixed-Income Securities in a series under which losses
in excess of those absorbed by any related class of Equity Securities are first
allocated to any Subordinate Securities up to a specified limit, cross-support
among Mortgage Assets and/or overcollateralization. See 'Subordination' and
'Description of Credit Enhancement' herein. Regardless of the form of Credit
Enhancement provided, the coverage will be limited in amount and in most cases
will be subject to periodic reduction in accordance with a schedule or formula.
Furthermore, such Credit Enhancements may provide only very limited coverage as
to certain types of losses, and may provide no coverage as to certain other
types of losses. Generally, Credit Enhancements do not directly or indirectly
guarantee to the investors any specified rate of prepayments. The Master
Servicer will generally be permitted to reduce, terminate or substitute all or a
portion of the Credit Enhancement for any series of Securities, if the
applicable Rating Agency indicates that the then-current rating thereof will not
be adversely affected. To the extent not set forth herein, the amount and types
of coverage, the identification of any entity providing the coverage, the terms
of any subordination and related information will be set forth in the Prospectus
Supplement relating to a series of Securities. See 'Description of Credit
Enhancement' and 'Subordination.'
 
                                       13

RISKS OF THE MORTGAGE LOANS
 
     Risk of the Losses Associated with Junior Liens.  Certain of the Mortgage
Loans will be secured by junior liens subordinate to the rights of the mortgagee
or beneficiary under each related senior mortgage or deed of trust. As a result,
the proceeds from any liquidation, insurance or condemnation proceedings will be
available to satisfy the principal balance of a mortgage loan only to the extent
that the claims, if any, of each such senior mortgagee or beneficiary are
satisfied in full, including any related foreclosure costs. In addition, a
mortgagee secured by a junior lien may not foreclose on the related mortgaged
property unless it forecloses subject to the related senior mortgage or
mortgages, in which case it must either pay the entire amount of each senior
mortgage to the applicable mortgagee at or prior to the foreclosure sale or
undertake the obligation to make payments on each senior mortgage in the event
of default thereunder. In servicing junior lien loans in its portfolio, it has
been the practice of the Master Servicer to satisfy each such senior mortgage at
or prior to the foreclosure sale only to the extent that it determines any
amounts so paid will be recoverable from future payments and collections on such
junior lien loans or otherwise. The Trusts will not have any source of funds to
satisfy any such senior mortgage or make payments due to any senior mortgagee.
See 'Certain Legal Aspects of Mortgage Loans and Related Matters--Foreclosure.'
 
     Risk of Losses Associated with Declining Real Estate Values.  An investment
in securities such as the Securities that generally represent beneficial
ownership interests in the Mortgage Loans or debt secured by such Mortgage Loans
may be affected by, among other things, a decline in real estate values and
changes in the borrowers' financial condition. No assurance can be given that
values of the Mortgaged Properties have remained or will remain at their levels
on the dates of origination of the related Mortgage Loans. If the residential

real estate market should experience an overall decline in property values such
that the outstanding balances of any senior liens, the Mortgage Loans and any
secondary financing on the Mortgaged Properties in a particular Mortgage Pool
become equal to or greater than the value of the Mortgaged Properties, the
actual rates of delinquencies, foreclosures and losses could be higher than
those now generally experienced in the nonconforming credit mortgage lending
industry. Such a decline could extinguish the interest of the related Trust in
the Mortgaged Properties before having any effect on the interest of the related
senior mortgagee. In addition, in the case of Mortgage Loans that are subject to
negative amortization, due to the addition to principal balance of deferred
interest ('Deferred Interest'), the principal balances of such Mortgage Loans
could be increased to an amount equal to or in excess of the value of the
underlying Mortgaged Properties, thereby increasing the likelihood of default.
To the extent that such losses are not covered by the applicable Credit
Enhancement, holders of Securities of the series evidencing interests in the
related Mortgage Pool will bear all risk of loss resulting from default by
Mortgagors and will have to look primarily to the value of the Mortgaged
Properties for recovery of the outstanding principal and unpaid interest on the
defaulted Mortgage Loans.
 
     Risk of Losses Associated with Certain Non-Conforming Credit and
Non-Traditional Loans.  The Sponsor's underwriting standards consider, among
other things, a mortgagor's credit history, repayment ability and debt
service-to-income ratio, as well as the value of the property; however, the
Sponsor's Mortgage Loan program generally provides for the origination of
Mortgage Loans relating to non-conforming credits. For purposes hereof,
'non-conforming credit' means a mortgage loan which, based upon standard
underwriting guidelines, is ineligible for purchase by the Federal National
Mortgage Association ('FNMA') or the Federal Home Loan Mortgage Corporation
('FHLMC') due to credit characteristics that do not meet FNMA or FHLMC
guidelines, respectively. Certain of the types of loans that may be included in
the Mortgage Pools may involve additional uncertainties not present in
traditional types of loans. For example, certain of the Mortgage Loans may
provide for escalating or variable payments by the borrower under the Mortgage
Loan (the 'Mortgagor'), as to which the Mortgagor is generally qualified on the
basis of the initial payment amount. In some instances the Mortgagors' income
may not be sufficient to enable them to continue to make their loan payments as
such payments increase and thus the likelihood of default will increase. For a
more detailed discussion, see 'Mortgage Loan Program.'
 
     Risk of Losses Associated with Balloon Loans.  Certain of the Mortgage
Loans may constitute 'Balloon Loans.' Balloon Loans are originated with a stated
maturity of less than the period of time of the corresponding amortization
schedule. Consequently, upon the maturity of a Balloon Loan, the Mortgagor will
be required to make a 'balloon' payment that will be significantly larger than
such Mortgagor's previous monthly payments. The ability of such a Mortgagor to
repay a Balloon Loan at maturity frequently will depend on such borrower's
 
                                       14

ability to refinance the Mortgage Loan. The ability of a Mortgagor to refinance
such a Mortgage Loan will be affected by a number of factors, including the
level of available mortgage rates at the time, the value of the related
Mortgaged Property, the Mortgagor's equity in the related Mortgaged Property,

the financial condition of the Mortgagor, the tax laws and general economic
conditions at the time.
 
     Although a low interest rate environment may facilitate the refinancing of
a balloon payment, the receipt and reinvestment by Securityholders of the
proceeds in such an environment may produce a lower return than that previously
received in respect of the related Mortgage Loan. Conversely, a high interest
rate environment may make it more difficult for the Mortgagor to accomplish a
refinancing and may result in delinquencies or defaults. None of the Sponsor,
the Originators, the Master Servicer, any Sub-Servicer or the Trustee will be
obligated to provide funds to refinance any Mortgage Loan, including Balloon
Loans.
 
     Risk of Losses Associated with ARM Loans.  ARM Loans may be underwritten on
the basis of an assessment that Mortgagors will have the ability to make
payments in higher amounts after relatively short periods of time. In some
instances, Mortgagors' income may not be sufficient to enable them to continue
to make their loan payments as such payments increase and thus the likelihood of
default will increase.
 
     Risk of Losses Associated with Bankruptcy of Mortgagors.  General economic
conditions have an impact on the ability of borrowers to repay Mortgage Loans.
Loss of earnings, illness and other similar factors also may lead to an increase
in delinquencies and bankruptcy filings by borrowers. In the event of personal
bankruptcy of a Mortgagor, it is possible that a Trust could experience a loss
with respect to such Mortgagor's Mortgage Loan. In conjunction with a
Mortgagor's bankruptcy, a bankruptcy court may suspend or reduce the payments of
principal and interest to be paid with respect to such Mortgage Loan or
permanently reduce the principal balance of such Mortgage Loan thereby either
delaying or permanently limiting the amount received by the Trust with respect
to such Mortgage Loan. Moreover, in the event a bankruptcy court prevents the
transfer of the related Mortgaged Property to a Trust, any remaining balance on
such Mortgage Loan may not be recoverable.
 
     Risk of Losses Associated with Mortgaged Properties.  Even assuming that
the Mortgaged Properties provide adequate security for the Mortgage Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Mortgage Loans and corresponding delays in the receipt of related
proceeds by the Securityholders could occur. An action to foreclose on a
Mortgaged Property securing a Mortgage Loan is regulated by state statutes,
rules and judicial decisions 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
Mortgaged Property. In the event of a default by a Mortgagor, these
restrictions, among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Mortgaged Property or to obtain liquidation proceeds
(net of expenses) ('Liquidation Proceeds') sufficient to repay all amounts due
on the related Mortgage Loan. The Master Servicer will be entitled to deduct
from Liquidation Proceeds all expenses reasonably incurred in attempting to
recover amounts due on the related liquidated Mortgage Loan ('Liquidated
Mortgage Loan') and not yet repaid, including payments to prior lienholders,
accrued Servicing Fees, legal fees and costs of legal action, real estate taxes,
and maintenance and preservation expenses. In the event that any Mortgaged

Properties fail to provide adequate security for the related Mortgage Loans and
insufficient funds are available from any applicable Credit Enhancement,
Securityholders could experience a loss on their investment.
 
     Liquidation expenses with respect to defaulted mortgage loans do not vary
directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer takes the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a larger principal
balance, the amount realized after expenses of liquidation would be less as a
percentage of the outstanding principal balance of the smaller principal balance
mortgage loan than would be the case with a larger principal balance loan.
 
     Under environmental legislation and judicial decisions applicable in
various states, a secured party that takes a deed in lieu of foreclosure, or
acquires at a foreclosure sale a mortgaged property that, prior to foreclosure,
has been involved in decisions or actions which may lead to contamination of a
property, may be liable for the costs of cleaning up the purportedly
contaminated site. Although such costs could be substantial, it is unclear
whether they would be imposed on a holder of a mortgage note (such as a Trust)
which, under the terms of the Pooling
 
                                       15

and Servicing Agreement, is not required to take an active role in operating the
Mortgaged Properties. See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Environmental Legislation.'
 
     Certain of the Mortgaged Properties relating to Mortgage Loans may not be
owner occupied. It is possible that the rate of delinquencies, foreclosures and
losses on Mortgage Loans secured by nonowner occupied properties could be higher
than for loans secured by the primary residence of the borrower.
 
     Litigation.  Any material litigation relating to the Sponsor or the Master
Servicer will be specified in the related Prospectus Supplement.
 
     Geographic Concentration of Mortgaged Properties.  Certain geographic
regions from time to time will experience weaker regional economic conditions
and housing markets than will other regions, and, consequently, will experience
higher rates of loss and delinquency on mortgage loans generally. The Mortgage
Loans underlying certain series of Securities may be concentrated in such
regions, and such concentrations may present risk considerations in addition to
those generally present for similar mortgage loan asset-backed securities
without such concentrations. Information with respect to geographic
concentration of Mortgaged Properties will be specified in the related
Prospectus Supplement or related Current Report on Form 8-K.
 
     Legal Considerations.  Applicable state laws generally regulate interest
rates and other charges, require certain disclosures, and require licensing of
the Originators and the Master Servicer and Sub-Servicers. In addition, most
states have other laws, public policy and general principles of equity relating
to the protection of consumers, unfair and deceptive practices and practices
that may apply to the origination, servicing and collection of the Mortgage
Loans. Depending on the provisions of the applicable law and the specific facts

and circumstances involved, violations of these laws, policies and principles
may limit the ability of the Master Servicer to collect all or part of the
principal of or interest on the Mortgage Loans, may entitle the borrower to a
refund of amounts previously paid and, in addition, could subject the Master
Servicer to damages and administrative sanctions. See 'Certain Legal Aspects of
Mortgage Loans and Related Matters.'
 
     The Mortgage Loans may also be subject to federal laws, including: (i) the
Federal Truth-in-Lending Act and Regulation Z promulgated thereunder and the
Real Estate Settlement Procedures Act and Regulation X promulgated thereunder,
which require certain disclosures to the borrowers regarding the terms of the
Mortgage Loans; (ii) the Equal Credit Opportunity Act and Regulation B
promulgated thereunder, which prohibit discrimination on the basis of age, race,
color, sex, religion, marital status, national origin, receipt of public
assistance or the exercise of any right under the Consumer Credit Protection
Act, in the extension of credit; and (iii) the Fair Credit Reporting Act, which
regulates the use and reporting of information related to the borrower's credit
experience. Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and general
principles of equity may limit the ability of the Master Servicer to collect all
or part of the principal of or interest on the Mortgage Loans, may entitle the
borrower to rescind the loan or to a refund of amounts previously paid and, in
addition, could subject the Master Servicer to damages and administrative
sanctions. If the Master Servicer is unable to collect all or part of the
principal or interest on the Mortgage Loans because of a violation of the
aforementioned laws, public policies or general principles of equity then the
Trust may be delayed or unable to repay all amounts owed to Investors.
Furthermore, depending upon whether damages and sanctions are assessed against
the Master Servicer or an Originator, such violations may materially impact the
financial ability of the Sponsor to continue to act as Master Servicer or the
ability of an Originator to repurchase or replace Mortgage Loans if such
violation breaches a representation or warranty contained in a Pooling and
Servicing Agreement.
 
     Yield and Prepayment Considerations.  The yield to maturity of the
Securities of each series will depend on the rate of payment of principal
(including prepayments, liquidations due to defaults, and repurchases due to
conversion of adjustable-rate mortgage loans ('ARM Loans') to fixed-rate loans
or breaches of representations and warranties) on the Mortgage Loans and the
price paid by Securityholders. Such yield may be adversely affected by a higher
or lower than anticipated rate of prepayments on the related Mortgage Loans. The
yield to maturity on Strip Securities or Securities purchased at premiums or
discounted to par will be extremely sensitive to the rate of prepayments on the
related Mortgage Loans. In addition, the yield to maturity on certain other
types of classes of Securities, including Accrual Securities or certain other
classes in a series including more than one class of Securities, may be
relatively more sensitive to the rate of prepayment on the related Mortgage
Loans than other classes of Securities.
 
                                       16

     Unless otherwise specified in the related Prospectus Supplement, the
Mortgage Loans may be prepaid in full or in part at any time; however, a
prepayment penalty or premium may be imposed in connection therewith. Unless so

specified in the related Prospectus Supplement, such penalties will not be
property of the related Trust. The rate of prepayments of the Mortgage Loans
cannot be predicted and is influenced by a wide variety of economic, social, and
other factors, including prevailing mortgage market in terest rates, the
availability of alternative financing, local and regional economic conditions
and homeowner mobility. Therefore, no assurance can be given as to the level of
prepayments that a Trust will experience.
 
     Prepayments may result from mandatory prepayments relating to unused moneys
held in Pre-Funding Accounts, if any, voluntary early payments by borrowers
(including payments in connection with refinancings of the related senior
Mortgage Loan or Loans), sales of Mortgaged Properties subject to 'due-on-sale'
provisions and liquidations due to default, as well as the receipt of proceeds
from physical damage, credit life and disability insurance policies. In
addition, repurchases or purchases from a Trust of Mortgage Loans or
substitution adjustments required to be made under the Pooling and Servicing
Agreement will have the same effect on the Securityholders as a prepayment of
such Mortgage Loans. Unless otherwise specified in the related Prospectus
Supplement, all of the Mortgage Loans contain 'due-on-sale' provisions, and the
Master Servicer will be required to enforce such provisions unless (i) the
'due-on-sale' clause, in the reasonable belief of the Master Servicer, is not
enforceable under applicable law or (ii) the Master Servicer reasonably believes
that to permit an assumption of the Mortgage Loan would not materially and
adversely affect the interests of the Securityholders or of the related Credit
Enhancer, if any. See 'The Pooling and Servicing Agreement' in the related
Prospectus Supplement.
 
     Collections on the Mortgage Loans may vary due to the level of incidence of
delinquent payments and of prepayments. Collections on the Mortgage Loans may
also vary due to seasonal purchasing and payment habits of borrowers.
 
     Book-Entry Registration.  Issuance of the Securities in book-entry form may
reduce the liquidity of such Securities in the secondary trading market since
investors may be unwilling to purchase Securities for which they cannot obtain
definitive physical securities representing such Securityholders' interests,
except in certain circumstances described in the related Prospectus Supplement.
 
     Since transactions in Securities will, in most cases, be able to be
effected only through DTC, direct or indirect participants in DTC's book-entry
system ('Direct or Indirect Participants') and certain banks, the ability of a
Securityholder to pledge a 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 security representing the
Securities.
 
     Securityholders may experience some delay in their receipt of distributions
of interest on and principal of the Securities since distributions may be
required to be forwarded by the Trustee to DTC and, in such a case, DTC will be
required to credit such distributions to the accounts of its Participants which
thereafter will be required to credit them to the accounts of the applicable
class of Securityholders either directly or indirectly through Indirect
Participants. See 'Description of the Securities--Form of Securities.'
 
     The Status of the Mortgage Loans in the Event of Bankruptcy of the Sponsor

or an Originator.  In the event of the bankruptcy of the Sponsor or an
Originator at a time when it or any affiliate thereof holds an Equity Security,
a trustee in bankruptcy of the Sponsor, an Originator, or its creditors could
attempt to recharacterize the sale of the Mortgage Loans to the related Trust as
a borrowing by the Sponsor, the Originator or such affiliate with the result, if
such recharacterization is upheld, that the Securityholders would be deemed
creditors of the Sponsor, the Originator or such affiliate, secured by a pledge
of the Mortgage Loans. If such an attempt were successful, it could prevent
timely payments of amounts due to the Trust.
 
     Limitations on Interest Payments and Foreclosures.  Generally, under the
terms of the Soldiers' and Sailors' Civil Relief Act of 1940, as amended (the
'Relief Act'), or similar state legislation, a Mortgagor who enters military
service after the origination of the related Mortgage Loan (including a
Mortgagor who is a member of the National Guard or is in reserve status at the
time of the origination of the Mortgage Loan and is later called to active duty)
may not be charged interest (including fees and charges) above an annual rate of
6% during the period of such Mortgagor's active duty status, unless a court
orders otherwise upon application of the
 
                                       17

lender. It is possible that such action could have an effect, for an
indeterminate period of time, on the ability of the Master Servicer to collect
full amounts of interest on certain of the Mortgage Loans. In addition, the
Relief Act imposes limitations that would impair the ability of the Master
Servicer to foreclose on an affected Mortgage Loan during the Mortgagor's period
of active duty status. Thus, in the event that such a Mortgage Loan goes into
default, there may be delays and losses occasioned by the inability to realize
upon the Mortgaged Property in a timely fashion.
 
     Security Rating.  The rating of Securities credit enhanced through external
Credit Enhancement such as a letter of credit, financial guaranty insurance
policy or mortgage pool insurance will depend primarily on the creditworthiness
of the issuer of such external Credit Enhancement device (a 'Credit Enhancer').
Any reduction in the rating assigned to the claims-paying ability of the related
Credit Enhancer below the rating initially given to the Securities would likely
result in a reduction in the rating of the Securities. See 'Ratings' in the
Prospectus Supplement.
 
                                   THE TRUSTS
 
     A Trust for any series of Securities will include the primary mortgage
assets ('Mortgage Assets') consisting of (A) a Mortgage Pool comprised of (i)
Single Family Loans, (ii) Multi-family Loans, (iii) Cooperative Loans, (iv)
Contracts, (v) Home Improvement Loans, or (vi) other loans or (B) certificates
of interest or participation in the items described in clause (A) or in pools of
such items, in each case, as specified in the related Prospectus Supplement,
together with payments in respect of such primary Mortgage Assets and certain
other accounts, obligations or agreements, in each case as specified in the
related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities will be entitled to payment only from the assets of the related Trust

(i.e., the related Trust Estate) and will not be entitled to payments in respect
of the assets of any other related Trust Estate established by the Sponsor, the
Originators or any of their affiliates. If specified in the related Prospectus
Supplement, certain Securities will evidence the entire fractional undivided
ownership interest in the related Mortgage Loans held by the related Trust or
may represent debt secured by the related Mortgage Loans.
 
     The following is a brief description of the Mortgage Assets expected to be
included in the related Trusts. If specific information respecting the primary
Mortgage Assets is not known at the time the related series of Securities
initially is offered, 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 Commission within fifteen days after the
initial issuance of such Securities (the 'Detailed Description'). A copy of the
Pooling and Servicing Agreement with respect to each Series of Securities will
be attached to the Form 8-K and will be available for inspection at the
corporate trust office of the Trustee specified in the related Prospectus
Supplement. A schedule of the Mortgage Assets relating to such Series (the
'Mortgage Asset Schedule') will be attached to the Pooling and Servicing
Agreement delivered to the Trustee upon delivery of the Securities.
 
     The Mortgage Loans--General.  The real properties and Manufactured Homes,
as the case may be, that secure repayment of the Mortgage Loans and Contracts
(the 'Mortgaged Properties') may be located in any one of the fifty states, the
District of Columbia, Puerto Rico or any other Territories of the United States.
Unless otherwise specified in the related Prospectus Supplement, the Mortgage
Loans or Contracts will be 'Conventional Loans' (i.e., loans that are not
insured or guaranteed by any governmental agency). If specified in the related
Prospectus Supplement, Mortgage Loans with certain loan-to-value ratios and/or
certain principal balances may be covered wholly or partially by primary
mortgage insurance policies. Unless otherwise specified in the related
Prospectus Supplement, all of the Mortgage Loans will be covered by standard
hazard insurance policies (which may be in the form of a blanket or forced
placed hazard insurance policy). The existence, extent and duration of any such
coverage will be described in the applicable Prospectus Supplement. Unless
otherwise described in the related Prospectus Supplement, the Mortgage Loans
will not be guaranteed or insured by any government agency or other insurer.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Mortgage Loans in a Mortgage Pool will provide for payments to be made monthly
('monthly pay') or bi-weekly. The payment terms of the Mortgage Loans to be
included in a Trust will be described in the related Prospectus Supplement and
may
 
                                       18

include any of the following features or combination thereof or other features
described in the related Prospectus Supplement:
 
          (a) Interest may be payable at a Fixed Rate, or an Adjustable Rate
     (i.e., a rate that is adjustable from time to time in relation to an index,
     a rate that is fixed for a period of time and under certain circumstances
     is followed by an adjustable rate, a rate that otherwise varies from time
     to time, or a rate that is convertible from an adjustable rate to a fixed

     rate). The specified rate of interest on a Mortgage Loan is its 'Mortgage
     Rate.' 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 Mortgage Loan for such periods and under such circumstances as may be
     specified in the related Prospectus Supplement. If provided for in the
     Prospectus Supplement, certain Mortgage Loans may be subject to temporary
     buydown plans ('Buydown Mortgage Loans') pursuant to which the monthly
     payments made by the Mortgagor during the early years of the Mortgage Loan
     (the 'Buydown Period') will be less than the scheduled monthly payments on
     the Mortgage Loan, and the amount of any difference may be contributed from
     (i) an amount (such amount, exclusive of investment earnings thereon, being
     hereinafter referred to as 'Buydown Funds') funded by the originator of the
     Mortgage Loan or another source (including the Master Servicer or the
     related Originator and the builder of the Mortgaged Property) and placed in
     a custodial account (the 'Buydown Account') and (ii) if the Buydown Funds
     are contributed on a present value basis, investment earnings on such
     Buydown Funds.
 
          (b) Principal may be payable on a level debt service basis to fully
     amortize the Mortgage 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
     Mortgage Rate, or may not be amortized during all or a portion of the
     original term. Payment of all or a substantial portion of the principal may
     be due on maturity ('balloon payments'). Principal may include interest
     that has been deferred and added to the principal balance of the Mortgage
     Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the Mortgage Loan, may increase over a specified period of time
     ('graduated payments') or may change from period to period. Mortgage 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. Mortgage Loans having graduated payment provisions may provide
     for deferred payment of a portion of the interest due monthly during a
     specified period, and recoup the deferred interest through negative
     amortization during such period whereby the difference between the interest
     paid during such period and interest accrued during such period is added
     monthly to the outstanding principal balance. Other Mortgage Loans
     sometimes referred to as 'growing equity' mortgage loans may provide for
     periodic scheduled payment increases for a specified period with the full
     amount of such increases being applied to principal.
 
          (d) Prepayments of principal may be subject to a prepayment fee, which
     may be fixed for the life of the Mortgage Loan or may decline over time,
     and may be prohibited for the life of the Mortgage Loan or for certain
     periods ('lockout periods'). Certain Mortgage Loans may permit prepayments
     after expiration of the applicable lockout period and may require the
     payment of a prepayment fee in connection therewith. Other Mortgage Loans
     may permit prepayments without payment of a fee unless the prepayment
     occurs during specified time periods. The Mortgage Loans may include
     due-on-sale clauses which permit the mortgagee to demand payment of the
     entire Mortgage Loan in connection with the sale or certain transfers of

     the related Mortgaged Property. Other Mortgage Loans may be assumable by
     persons meeting the then applicable underwriting standards of the related
     Originator.
 
   
          (e) As more fully described in the related Prospectus Supplement, the
     Mortgage Loans may consist, in whole or in part, of revolving home equity
     loans or certain balances thereof ('Revolving Credit Line Loans'). Interest
     on each Revolving Credit Line Loan, excluding introductory rates offered
     from time to time during promotional periods, may be computed and payable
     monthly on the average daily outstanding principal balance of such loan.
     From time to time prior to the expiration of the related draw period
     specified in a Revolving Credit Line Loan, principal amounts on such
     Revolving Credit Line Loan may be drawn down (up to a maximum amount as set
     forth in the related Prospectus Supplement) or repaid. If specified in the
     related Prospectus Supplement, new draws by borrowers under the Revolving
     Credit Line Loans will
    
 
                                       19

   
     automatically become part of the Trust Estate described in such Prospectus
     Supplement. As a result, the aggregate balance of the Revolving Credit Line
     Loans will fluctuate from day to day as new draws by borrowers are added to
     the Trust Estate and principal payments are applied to such balances and
     such amounts will usually differ each day, as more specifically described
     in the related Prospectus Supplement. Under certain circumstances, under a
     Revolving Credit Line Loan, a borrower may, during the related draw period,
     choose an interest only payment option, during which the borrower is
     obligated to pay only the amount of interest which accrues on the loan
     during the billing cycle, and may also elect to pay all or a portion of the
     principal. An interest only payment option may terminate at the end of the
     related draw period, after which the borrower must begin paying at least a
     minimum monthly portion of the average outstanding principal balance of the
     loan.
    
 
     Except as otherwise described in the related Prospectus Supplement or in
the related Current Report on Form 8-K, interest will be calculated on each
Mortgage Loan pursuant to one of three methods:
 
          Date of Payment Loans.  Date of Payment Loans provide that interest is
     charged to the Mortgagor at the applicable Mortgage Rate on the outstanding
     principal balance of such Note and calculated based on the number of days
     elapsed between receipt of the Mortgagor's last payment through receipt of
     the Mortgagor's most current payment. Such interest is deducted from the
     Mortgagor's payment amount and the remainder, if any, of the payment is
     applied as a reduction to the outstanding principal balance of such Note.
     Although the Mortgagor is required to remit equal monthly payments on a
     specified monthly payment date that would reduce the outstanding principal
     balance of such Note to zero at such Note's maturity date, payments that
     are made by the Mortgagor after the due date therefor would cause the
     outstanding principal balance of such Note not to be reduced to zero. In

     such a case, the Mortgagor would be required to make an additional
     principal payment at the maturity date for such Note. On the other hand, if
     a Mortgagor makes a payment (other than a prepayment) before the due date
     therefor, the reduction in the outstanding principal balance of such Note
     would occur over a shorter period of time than it would have occurred had
     it been based on the original amortization schedule of such Note.
 
          Actuarial Loans.  Actuarial Loans provide that interest is charged to
     the Mortgagor thereunder, and payments are due from such Mortgagor, as of a
     scheduled day of each month which is fixed at the time of origination.
     Scheduled monthly payments made by the Mortgagors on the Actuarial Loans
     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.
 
          Rule of 78's Loans.  A Rule of 78's Loan provides for the payment by
     the related Mortgagor of a specified total amount of payments, payable in
     equal monthly installments on each due date, which total represents the
     principal amount financed and add-on interest in an amount calculated on
     the basis of the stated Mortgage Rate for the term of the Loan. The rate at
     which such amount of add-on interest is earned and, correspondingly, the
     amount of each fixed monthly payment allocated to reduction of the
     outstanding principal are calculated in accordance with the 'Rule of 78's.'
     Under a Rule of 78's Loan, the amount of a payment allocable to interest is
     determined by multiplying the total amount of add-on interest payable over
     the term of the loan by a fraction derived as described below.
 
     The fraction used in the calculation of add-on interest earned each month
under a Rule of 78's Loan has as its denominator a number equal to the sum of a
series of numbers. The series of numbers begins with one and ends with the
number of monthly payments due under the loan. For example, with a loan
providing for 12 payments, the denominator of each month's fraction will be 78,
the sum of the series of numbers from 1 to 12. The numerator of the fraction for
a given month is the number of original payments to stated maturity less the
number of payments made up to but not including the current month. Accordingly,
in the example of a twelve-month loan, the fraction for the first payment is,
for the second payment, for the third party, and so on through the final
payment, for which the fraction is. The applicable fraction is then multiplied
by the total add-on interest payable over the entire term of the loan, and the
resulting amount is the amount of add-on interest 'earned' that month. The
difference between the amount of the monthly payment by the obligor and the
amount of earned add-on interest calculated for the month is applied to
principal reduction. Rule of 78's Loans are non-level yield instruments. The
yield in the initial months of a Rule of 78's Loans is somewhat higher than the
stated Mortgage
 
                                       20

Rate (computed on an actuarial basis) and the yield in the later months of the
loan is somewhat less than such stated Mortgage Rate.
 
     The Prospectus Supplement for each series of Securities or the Current
Report on Form 8-K will contain certain information with respect to the Mortgage
Loans (or a sample thereof) contained in the related Mortgage Pool; such

information, insofar as it may relate to statistical information relating to
such Mortgage Loans will be presented as of a date certain (the 'Statistic
Calculation Date') which may also be the related cut-off date (the 'Cut-Off
Date'). Such information will include to the extent applicable to the particular
Mortgage Pool (in all cases as of the Statistic Calculation Date) (i) the
aggregate outstanding principal balance and the average outstanding principal
balance of the Mortgage Loans, (ii) the largest principal balance and the
smallest principal balance of any of the Mortgage Loans, (iii) the types of
Mortgaged Property securing the Mortgage Loans (e.g., one- to four-family
houses, vacation and second homes, Manufactured Homes, multifamily apartments or
other real property), (iv) the original terms to stated maturity of the Mortgage
Loans, (v) the weighted average remaining term to maturity of the Mortgage Loans
and the range of the remaining terms to maturity; (vi) the earliest origination
date and latest maturity date of any of the Mortgage Loans, (vii) the weighted
average CLTV and the range of CLTV's of the Mortgage Loans at origination,
(viii) the weighted average Mortgage Rate or annual percentage rate (as
determined under Regulation Z) (the 'APR') and ranges of Mortgage Rates or APRs
borne by the Mortgage Loans, (ix) in the case of Mortgage Loans having
adjustable rates, the weighted average of the adjustable rates and indices, if
any; (x) the aggregate outstanding principal balance, if any, of Buy-Down Loans
and Mortgage Loans having graduated payment provisions; (xi) the amount of any
mortgage pool insurance policy, special hazard insurance policy or bankruptcy
bond to be maintained with respect to such Mortgage Pool; (xii) a description of
any standard hazard insurance required to be maintained with respect to each
Mortgage Loan; (xiii) a description of any Credit Enhancement to be provided
with respect to all or any Mortgage Loans or the Mortgage Pool; and (xiv) the
geographical distribution of the Mortgage Loans on a state-by-state basis. In
addition, preliminary or more general information of the nature described above
may be provided in the Prospectus Supplement, and specific or final information
may be set forth in a Current Report on Form 8-K, together with the related
Pooling and Servicing Agreement, which will be filed with the Securities and
Exchange Commission and will be made available to holders of the related series
of Securities within fifteen days after the initial issuance of such Securities.
 
     The loan-to-value ratio (the 'LTV') of a Mortgage Loan is equal to the
ratio (expressed as a percentage) of the original principal balance of such
Mortgage Loan to appraised value of the related Mortgaged Property (unless
otherwise disclosed in the related Prospectus Supplement or in the related
Current Report on Form 8-K, less the amount, if any, of the premium for any
credit life insurance) at the time of origination of the Mortgage Loan or, in
the case where the Mortgage represents a purchase money instrument, the lesser
of (a) the appraised value or (b) the purchase price. The combined loan-to-value
ratio (the 'CLTV') of a Mortgage Loan at any given time is the ratio, expressed
as a percentage, determined by dividing (x) the sum of the original principal
balance of such Mortgage Loan (unless otherwise disclosed in the related
Prospectus Supplement or in the related Current Report on Form 8-K, less the
amount, if any, of the premium for any credit life insurance) plus the then-
current principal balance of all mortgage loans (each, a 'Senior Lien') secured
by liens on the related Mortgaged Property having priorities senior to that of
the lien which secures such Mortgage Loan, by (y) the value of the related
Mortgaged Property, based upon the appraisal or valuation (which may in certain
instances include estimated increases in value as a result of certain home
improvements to be financed with the proceeds of such Mortgage Loan) made at the
time of origination of the Mortgage Loan. If the related Mortgagor will use the

proceeds of the Mortgage Loan to refinance an existing Mortgage Loan which is
being serviced directly or indirectly by the Master Servicer, the requirement of
an appraisal or other valuation at the time the new Mortgage Loan is made may be
waived. Unless otherwise specified in the related Prospectus Supplement, for
purposes of calculating the CLTV of a Contract relating to a new Manufactured
Home, the value of such Manufactured Home will be no greater than the sum of a
fixed percentage of the list price of the unit actually billed by the
manufacturer to the dealer (exclusive of freight to the dealer site) including
'accessories' identified in the invoice (the 'Manufacturer's Invoice Price'),
plus the actual cost of any accessories purchased from the dealer, a delivery
and set-up allowance, depending on the size of the unit, and the cost of state
and local taxes, filing fees and up to three years prepaid hazard insurance
premiums. Unless otherwise specified herein or in the related Prospectus
Supplement, the value of a used Manufactured Home will be either (x) the
appraised value, and National Automobile Dealer's Association book value plus
prepaid taxes and hazard insurance premiums or
 
                                       21

(y) the sum of (i) the appraised value of the land to which the Manufactured
Home is attached and (ii) the appraised value of the Manufactured Home. The
appraised value of a Manufactured Home will be based upon the age and condition
of the manufactured housing unit and the quality and condition of the mobile
home park in which it is situated, if applicable.
 
     No assurance can be given that values of the Mortgaged Properties have
remained or will remain at their levels on the dates of origination of the
related Mortgage Loans. If the residential real estate market should experience
an overall decline in property values such that the outstanding principal
balances of the Mortgage Loans (plus any additional financing by other lenders
on the same Mortgaged Properties) in a particular Pool become equal to or
greater than the value of such Mortgaged Properties, the actual rates of
delinquencies, foreclosures and losses could be higher than those now generally
experienced in the non-conforming credit mortgage lending industry. An overall
decline in the market value of residential real estate, the general condition of
a Mortgaged Property, or other factors, could adversely affect the values of the
Mortgaged Properties such that the outstanding balances of the Mortgage Loans,
together with any additional liens on the Mortgaged Properties, equal or exceed
the value of the Mortgaged Properties. Under such circumstances, the actual
rates of delinquencies, foreclosures and losses could be higher than those now
generally experienced in the non-conforming credit mortgage lending industry.
 
     Certain Mortgage Loans may be secured by junior liens ('Junior Lien Loans')
subordinate to the rights of the mortgagee under any related senior mortgage(s).
The proceeds from any liquidation, insurance or condemnation of Mortgaged
Properties relating to Junior Lien Loans in a Mortgage Pool will be available to
satisfy the principal balance of such Junior Lien Loans only to the extent that
the claims, if any, of all related senior mortgagees, including any related
foreclosure costs, are satisfied in full. In addition, the Master Servicer may
not foreclose on a Mortgaged Property relating to a Junior Lien Loan unless it
forecloses subject to the related senior mortgage or mortgages, in which case it
must either pay the entire amount of each senior mortgage to the applicable
mortgagee at or prior to the foreclosure sale or undertake the obligation to
make payments on each senior mortgage in the event of default thereunder.

Generally, in servicing Junior Lien Loans in its loan portfolios, it has been
the Master Servicer's practice to satisfy each senior mortgage at or prior to a
foreclosure sale only to the extent that it determines any amounts so paid will
be recoverable from future payments and collections on the Mortgage Loans or
otherwise. The Trusts will not have any source of funds to satisfy any such
senior mortgage or make payments due to any senior mortgagee. See 'Certain Legal
Aspects of Mortgage Loans and Related Matters--Foreclosure.'
 
     Other factors affecting mortgagors' ability to repay Mortgage Loans include
excessive building resulting in an oversupply of housing stock or a decrease in
employment reducing the demand for units in an area; federal, state or local
regulations and controls affecting rents; prices of goods and energy;
environmental restrictions; increasing labor and material costs; and the
relative attractiveness of the Mortgaged Properties. To the extent that losses
on the Mortgage Loans are not covered by Credit Enhancements, such losses will
be borne, at least in part, by the Securityholders of the related series.
 
     The Sponsor will cause the Mortgage Loans comprising each Mortgage Pool to
be assigned to the Trustee named in the related Prospectus Supplement for the
benefit of the holders of the Securities of the related series. The Master
Servicer will service the Mortgage Loans, either directly or through
Sub-Servicers, pursuant to the Pooling and Servicing Agreement and will receive
a fee for such services. See 'Mortgage Loan Program' and 'The Pooling and
Servicing Agreement.' With respect to Mortgage Loans serviced through a
Sub-Servicer, the Master Servicer will remain liable for its servicing
obligations under the related Pooling and Servicing Agreement as if the Master
Servicer alone were servicing such Mortgage Loans.
 
     Unless otherwise specified in the related Prospectus Supplement, the only
obligations of the Sponsor and the Originators with respect to a series of
Securities will be to provide (or, where the Sponsor or an Originator acquired a
Mortgage Loan from another originator, obtain from such originator) certain
representations and warranties concerning the Mortgage Loans and to assign to
the Trustee for such series of Securities the Sponsor's or Originator's rights
with respect to such representations and warranties. See 'The Pooling and
Servicing Agreement.' The obligations of the Master Servicer with respect to the
Mortgage Loans will consist principally of its contractual servicing obligations
under the related Pooling and Servicing Agreement (including its obligation to
enforce the obligations of the Sub-Servicers or Originators as more fully
described herein under 'Mortgage Loan Program--Qualifications of Originators'
and 'The Pooling and Servicing Agreement') and
 
                                       22

its obligation, as described in the related Prospectus Supplement, to make
certain cash advances in the event of delinquencies in payments on, or
prepayments received with respect to, the Mortgage Loans in the amounts
described herein under 'Description of the Securities--Advances.' The
obligations of a Master Servicer to make advances may be subject to limitations,
to the extent provided herein and in the related Prospectus Supplement.
 
     Single Family and Cooperative Loans.  Unless otherwise specified in the
Prospectus Supplement, single family loans will consist of mortgage loans, deeds
of trust or participation or other beneficial interests therein, secured by

first or junior liens on one- to four-family residential properties ('Single
Family Loans'). The Mortgaged Properties relating to Single Family Loans will
consist of detached or semi-detached one-family dwelling units, two- to
four-family dwelling units, townhouses, rowhouses, individual condominium units
in condominium developments, individual units in planned unit developments, and
certain mixed use and other dwelling units. Such Mortgaged Properties may
include owner-occupied (which includes vacation and second homes) and non-owner
occupied investment properties.
 
     If so specified, the Single Family Loans may include loans or
participations therein secured by mortgages or deeds of trust on condominium
units in low- or high-rise condominium developments together with such
condominium units' appurtenant interests in the common elements of such
condominium developments. Unless otherwise specified, the Cooperative Loans will
be secured by security interests in or similar liens on stock, shares or
membership certificates issued by cooperatives and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in such cooperatives' buildings.
 
     Multi-family Loans.  Multi-family loans will consist of mortgage loans,
deeds of trust or participation or other beneficial interests therein, secured
by first or junior liens on rental apartment buildings or projects containing
five or more residential units ('Multi-family Loans').
 
     Mortgaged Properties that secure Multi-family Loans may include high-rise,
mid-rise and garden apartments.   Certain of the Multi-family Loans may be
secured by apartment buildings owned by Cooperatives. In such cases, the
Cooperative owns all the apartment units in the building and all common areas.
The Cooperative is owned by tenant-stockholders who, through ownership of stock,
shares or membership certificates in the corporation, receive proprietary leases
or occupancy agreements that confer exclusive rights to occupy specific
apartments or units. Generally, a tenant-stockholder of a Cooperative must make
a monthly payment to the Cooperative representing such tenant-stockholder's pro
rata share of the Cooperative's payments for its mortgage loan, real property
taxes, maintenance expenses and other capital or ordinary expenses. Those
payments are in addition to any payments of principal and interest the
tenant-stockholder must make on any loans to the tenant-stockholder secured by
its shares in the Cooperative. The Cooperative will be directly responsible for
building management and, in most cases, payment of real estate taxes and hazard
and liability insurance. A Cooperative's ability to meet debt service
obligations on a Multi-family Loan, as well as all other operating expenses,
will be dependent in large part on the receipt of maintenance payments from the
tenant-stockholders, as well as any rental income from units or commercial areas
the Cooperative might control. Unanticipated expenditures may in some cases have
to be paid by special assessments on the tenant-stockholders.
 
     Home Improvement Loans.  Unless otherwise specified in the Prospectus
Supplement, loans to make home improvements may be secured by first or junior
liens on conventional one- to four-family residential properties and
multi-family residential properties ('Home Improvement Loans'). Home Improvement
Loans may be conventional, or may be partially insured by the Federal Housing
Administration ('FHA') or another federal or state agency, as specified in the
related Prospectus Supplement. The loan proceeds from such Home Improvement
Loans are typically disbursed to an escrow agent which, according to guidelines

established by the Originators, releases such proceeds to the contractor upon
completion of the improvements or in draws as the work on the improvements
progresses. Costs incurred by the Mortgagor for loan origination including
origination points and appraisal, legal and title fees, are often included in
the amount financed. In addition, Home Improvement Loans generally provide
additional security to a first or junior mortgage loan because home improvements
typically retain or increase the value of a property.
 
     Contracts.  Contracts will consist of manufactured housing conditional
sales contracts and installment sales or loan agreements each secured by a
Manufactured Home ('Contracts'). Contracts may be conventional, insured
partially by the FHA or partially guaranteed by the Veterans Administration, as
specified in the related
 
                                       23

Prospectus Supplement. Unless otherwise specified in the related Prospectus
Supplement, each Contract will be fully amortizing and will bear interest at its
APR.
 
     Unless otherwise specified in the related Prospectus Supplement, the
'Manufactured Homes' securing the Contracts will consist of manufactured homes
within the meaning of 42 United States Code, Section 5402(6), which defines a
'manufactured home' as 'a structure, transportable in one or more sections,
which in the traveling mode, is eight body feet or more in width or forty body
feet or more in length, or, when erected on site, is three hundred twenty or
more square feet, and which is built on a permanent chassis and designed to be
used as a dwelling with or without a permanent foundation when connected to the
required utilities, and includes the plumbing, heating, air conditioning, and
electrical systems contained therein; except that such term shall include any
structure which meets all the requirements of [this] paragraph except the size
requirements and with respect to which the manufacturer voluntarily files a
certification required by the Secretary of Housing and Urban Development and
complies with the standards established under [this] chapter.'
 
     The related Prospectus Supplement will specify for the Contracts contained
in the related Trust, among other things, the date of origination of the
Contracts; the Mortgage Rates or the APRs on the Contracts; the Contract
Loan-to-Value Ratios; the minimum and maximum outstanding principal balances as
of the Statistic Calculation Date and the average outstanding principal balance;
the outstanding principal balances of the Contracts included in the related
Trust; and the original maturities of the Contracts and the last maturity date
of any Contract.
 
                                       24




                               THE MORTGAGE POOLS
 
GENERAL
 
     Unless otherwise specified in the related Prospectus Supplement, each
Mortgage Pool will consist primarily of (i) conventional Mortgage Loans, minus
any stripped portion of the interest payments due under the related Mortgage
Note that may have been retained by any Originator or broker ('Originator's
Retained Yield'), or any other interest retained by the Sponsor or any affiliate
of the Sponsor, evidenced by promissory notes (the 'Mortgage Notes') secured by
mortgages or deeds of trust or other similar security instruments creating a
lien on single-family (i.e., one- to four-family) residential, multi-family
properties or mixed use properties, or (ii) certificates of interest or
participations in such Mortgage Notes. The Mortgaged Properties will consist
primarily of attached or detached one-family dwelling units, two- to four-family
dwelling units, condominiums, townhouses, row houses, individual units in
planned-unit developments and certain other dwelling units, mixed use properties
and the fee, leasehold or other interests in the underlying real property. The
Mortgaged Properties may be owner-occupied (which includes second and vacation
homes) and non-owner occupied investment properties. If specified in the related
Prospectus Supplement relating to a series of Securities, a Mortgage Pool may
contain cooperative apartment loans ('Cooperative Loans') evidenced by
promissory notes ('Cooperative Notes') secured by security interests in shares
issued by cooperatives and in the related proprietary leases or occupancy
agreements granting exclusive rights to occupy specific dwelling units in the
related buildings. As used herein, unless the context indicates otherwise,
'Mortgage Loans' include Cooperative Loans, 'Mortgaged Properties' include
shares in the related cooperative and the related proprietary leases or
occupancy agreements securing Cooperative Notes, 'Mortgage Notes' include
Cooperative Notes and 'Mortgages' include security agreements with respect to
Cooperative Notes.
 
     Each Mortgage Loan will be selected by the Sponsor for inclusion in a
Mortgage Pool from among mortgage loans originated by one or more institutions
affiliated with the Sponsor (such affiliated institutions, the 'Affiliated
Originators'), or from banks, savings and loan associations, mortgage bankers,
mortgage brokers, investment banking firms, the RTC, the FDIC and other mortgage
loan originators or purchasers not affiliated with the Sponsor (such
unaffiliated institutions, the 'Unaffiliated Originators' and, collectively with
the Affiliated Originators, the 'Originators'), all as described below under
'Mortgage Loan Program.' The characteristics of the Mortgage Loans will be
described in the related Prospectus Supplement. Other mortgage loans available
for acquisition by a Trust may have characteristics that would make them
eligible for inclusion in a Mortgage Pool but may not be selected by the Sponsor
for inclusion in such Mortgage Pool.
 
     Each Security will evidence an interest in only the related Mortgage Pool
and corresponding Trust Estate, and not in any other Mortgage Pool or any other
Trust Estate (except in those limited situations whereby certain collections on
any Mortgage Loans in a related Mortgage Pool in excess of amounts needed to pay
the related securities may be deposited in a common, master reserve account that
provides Credit Enhancement for more than one series of Securities).

 
THE MORTGAGE POOLS
 
     Unless otherwise specified below or in the related Prospectus Supplement,
all of the Mortgage Loans in a Mortgage Pool will (i) have payments that are due
monthly or bi-weekly, (ii) be secured by Mortgaged Properties located in any of
the fifty states, the District of Columbia, Puerto Rico or any other Territories
of the United States and (iii) consist of one or more of the following types of
mortgage loans:
 
          (1) Fixed-rate, fully-amortizing mortgage loans (which may include
     mortgage loans converted from adjustable-rate mortgage loans or otherwise
     modified) providing for level monthly payments of principal and interest
     and terms at origination or modification of generally not more than 30
     years;
 
          (2) ARM Loans having original or modified terms to maturity of
     generally not more than 30 years with a related Mortgage Rate that adjusts
     periodically, at the intervals described in the related Prospectus
     Supplement (which may have adjustments in the amount of monthly payments at
     periodic intervals) over the term of the mortgage loan to equal the sum of
     a fixed percentage set forth in the related Mortgage Note (the
 
                                       25

     'Note Margin') and an index (the 'Index') to be specified in the related
     Prospectus Supplement, such as, by way of example: (i) U.S. Treasury
     securities of a specified constant maturity, (ii) weekly auction average
     investment yield of U.S. Treasury bills of specified maturities, (iii) the
     daily Bank Prime Loan rate made available by the Federal Reserve Board or
     as quoted by one or more specified lending institutions, (iv) the cost of
     funds of member institutions for the Federal Home Loan Bank of San
     Francisco, or (v) the interbank offered rates for U.S. dollar deposits in
     the London Markets, each calculated as of a date prior to each scheduled
     interest rate adjustment date that will be specified in the related
     Prospectus Supplement. The related Prospectus Supplement will set forth the
     relevant Index, and the related Prospectus Supplement or the related
     Current Report on Form 8-K will indicate the highest, lowest and
     weighted-average Note Margin with respect to the ARM Loans in the related
     Mortgage Pool. If specified in the related Prospectus Supplement, an ARM
     Loan may include a provision that allows the Mortgagor to convert the
     adjustable Mortgage Rate to a fixed rate at some point during the term of
     such ARM Loan subsequent to the initial payment date;
 
          (3) Fixed-rate, graduated payment mortgage loans having original or
     modified terms to maturity of generally not more than 30 years with monthly
     payments during the first year calculated on the basis of an assumed
     interest rate that will be lower than the Mortgage Rate applicable to such
     mortgage loan in subsequent years. Deferred Interest, if any, will be added
     to the principal balance of such mortgage loans;
 
          (4) Balloon mortgage loans ('Balloon Loans'), which are mortgage loans
     having original or modified terms to maturity of generally 5 to 15 years as
     described in the related Prospectus Supplement, which may have level

     monthly payments of principal and interest based generally on a 10- to
     30-year amortization schedule. The amount of the monthly payment may remain
     constant until the maturity date, upon which date the full outstanding
     principal balance on such Balloon Loan will be due and payable (such
     amount, the 'Balloon Amount');
 
          (5) Modified mortgage loans ('Modified Loans'), which are fixed or
     adjustable-rate mortgage loans providing for terms at the time of
     modification of generally not more than 30 years. Modified Loans may be
     mortgage loans which have been consolidated and/or have had various terms
     changed, mortgage loans which have been converted from adjustable rate
     mortgage loans to fixed rate mortgage loans, or construction loans which
     have been converted to permanent mortgage loans;
 
          (6) Another type of mortgage loan described in the related Prospectus
     Supplement; or
 
   
          (7) As more fully described in the related Prospectus Supplement, the
     Mortgage Loans may consist, in whole or in part, of Revolving Credit Line
     Loans. Interest on each Revolving Credit Line Loan, excluding introductory
     rates offered from time to time during promotional periods, may be computed
     and payable monthly on the average daily outstanding principal balance of
     such loan. From time to time prior to the expiration of the related draw
     period specified in a Revolving Credit Line Loan, principal amounts on such
     Revolving Credit Line Loan may be drawn down (up to a maximum amount as set
     forth in the related Prospectus Supplement) or repaid. If specified in the
     related Prospectus Supplement, new draws by borrowers under the Revolving
     Credit Line Loans will automatically become part of the Trust Estate
     described in such Prospectus Supplement. As a result, the aggregate balance
     of the Revolving Credit Line Loans will fluctuate from day to day as new
     draws by borrowers are added to the Trust Estate and principal payments are
     applied to such balances and such amounts will usually differ each day, as
     more specifically described in the related Prospectus Supplement. Under
     certain circumstances, under a Revolving Credit Line Loan, a borrower may,
     during the related draw period, choose an interest only payment option,
     during which the borrower is obligated to pay only the amount of interest
     which accrues on the loan during the billing cycle, and may also elect to
     pay all or a portion of the principal. An interest only payment option may
     terminate at the end of the related draw period, after which the borrower
     must begin paying at least a minimum monthly portion of the average
     outstanding principal balance of the loan.
    
 
     If provided for in the related Prospectus Supplement, a Mortgage Pool may
contain either or both of the following types of mortgage loans (i) ARM Loans
which allow the Mortgagors to convert the adjustable rates on such Mortgage
Loans to a fixed rate at some point during the life of such Mortgage Loans and
(ii) fixed rate mortgage loans which allow the Mortgagors to convert the fixed
rates on such Mortgage Loans to an adjustable
 
                                       26

rate at some point during the life of such Mortgage Loans (each such Mortgage

Loan described in (i) and (ii) above, a 'Convertible Mortgage Loan').
 
     If provided for in the related Prospectus Supplement, certain of the
Mortgage Loans may be Buydown Mortgage Loans pursuant to which the monthly
payments made by the Mortgagor during the Buydown Period will be less than the
scheduled monthly payments on the Mortgage Loan, the resulting difference to be
made up from (i) Buydown Funds funded by the Originator of the Mortgaged
Property or another source (including the Master Servicer or the related
Originator) and placed in the Buydown Account and (ii) if the Buydown Funds are
contributed on a present value basis, investment earnings on such Buydown Funds.
See 'Description of the Securities--Payments on Mortgage Loans; Deposits to
Distribution Account.' The terms of the Buydown Mortgage Loans, if such loans
are included in a Trust, will be as set forth in the related Prospectus
Supplement.
 
     The Sponsor will cause the Mortgage Loans constituting each Mortgage Pool
to be assigned to the Trustee named in the related Prospectus Supplement, for
the benefit of the holders of all of the Securities of a series. The Master
Servicer named in the related Prospectus Supplement will service the Mortgage
Loans, either directly or through other mortgage servicing institutions
(Sub-Servicers), pursuant to a Pooling and Servicing Agreement and will receive
a fee for such services. See 'Mortgage Loan Program' and 'Description of the
Securities.' With respect to those Mortgage Loans serviced by the Master
Servicer through a Sub-Servicer, the Master Servicer will remain liable for its
servicing obligations under the related Pooling and Servicing Agreement as if
the Master Servicer alone were servicing such Mortgage Loans, unless otherwise
described in the related Prospectus Supplement.
 
     The Sponsor and/or certain Originators may make certain representations and
warranties regarding the Mortgage Loans, but its assignment of the Mortgage
Loans to the Trustee will be without recourse. See 'Description of the
Securities--Assignment of Mortgage Loans.' The Master Servicer's obligations
with respect to the Mortgage Loans will consist principally of its contractual
servicing obligations under the related Pooling and Servicing Agreement
(including its obligation to enforce certain purchase and other obligations of
Sub-Servicers and of Originators, as more fully described herein under 'Mortgage
Loan Program-- Representations by Originators,' '--Sub-Servicing by Originators'
and 'Description of the Securities-- Assignment of Mortgage Loans,' and its
obligation, if any, to make certain cash advances in the event of delinquencies
in payments on or with respect to the Mortgage Loans and interest shortfalls due
to prepayment of Mortgage Loans, in amounts described herein under 'Description
of the Securities--Advances'). The obligation of the Master Servicer to make
delinquency advances will be limited to amounts which the Master Servicer
believes ultimately would be reimbursable out of the proceeds of liquidation of
the Mortgage Loans. See 'Description of the Securities--Advances.'
 
                             MORTGAGE LOAN PROGRAM
 
     As a general matter, the Sponsor's Mortgage Loan program will consist of
the origination and packaging of Mortgage Loans relating to non-conforming
credits. For purposes hereof, 'non-conforming credit' means a mortgage loan
which, based upon standard underwriting guidelines, is ineligible for purchase
by FNMA or FHLMC due to credit characteristics that do not meet FNMA or FHLMC
guidelines, respectively. However, certain of the Mortgage Loans will relate to

FNMA or FHLMC conforming credits.
 
     The Mortgagors generally will have taken out the related Mortgage Loans for
one or more of four reasons: (i) to purchase the related Mortgaged Property,
(ii) to refinance an existing mortgage loan on more favorable terms, (iii) to
consolidate debt, or (iv) to obtain cash proceeds by borrowing against the
Mortgagor's equity in the related Mortgaged Property; the Mortgage Loans
described in (i) are commonly referred to as purchase money loans and the
Mortgage Loans described in (ii), (iii) and (iv) on the whole are commonly
referred to as home equity loans.
 
     It is the Sponsor's practice to solicit existing Mortgagors with respect to
the possible refinancing of their existing Mortgages.
 
                                       27

UNDERWRITING GUIDELINES
 
     As more fully described below under 'Qualifications of Originators' and as
may also be described in greater detail in the related Prospectus Supplement,
there are various types of Originators that may participate in the Sponsor's
Mortgage Loan Program. Under the Sponsor's Mortgage Loan Program, the Sponsor
purchases and originates Mortgage Loans pursuant to three types of underwriting
guidelines: (1) standard underwriting guidelines according to the Sponsor's
Originator Guide, as modified from time to time, used by Affiliated Originators
and Unaffiliated Originators ('Sponsor's Guidelines'), (2) underwriting
guidelines utilized by certain Unaffiliated Originators and approved by the
Sponsor ('Approved Guidelines'), and (3) underwriting guidelines ('Bulk
Guidelines') used by Unaffiliated Originators of portfolios of Mortgage Loans
subsequently purchased in whole or part by the Sponsor as bulk acquisitions
('Bulk Acquisitions'). The respective underwriting guidelines are described
below.
 
     Sponsor's Guidelines.  The Sponsor's Guidelines are set forth in the
Sponsor's Originator Guide. The Sponsor's Guidelines are revised continuously
based on opportunities and prevailing conditions in the nonconforming credit
residential mortgage market, as well as the expected market for the resulting
Securities.
 
     Mortgage Loans originated by Affiliated Originators generally will, and
Mortgage Loans originated by Unaffiliated Originators may have been, originated
in accordance with the Sponsor's Guidelines as set forth in the Sponsor's
Originator Guide. However, certain of the Mortgage Loans may be employee or
preferred customer loans with respect to which, in accordance with such
Affiliate's mortgage loan programs, no income or asset verifications were
required. In addition, certain Originators may originate Mortgage Loans in
satisfaction of specified requirements of federal or state law applicable to
certain Originators, such as, by way of illustration, the federal Community
Reinvestment Act of 1977, which is applicable to banks; such Mortgage Loans
generally will not have been originated pursuant to the Sponsor's standard
underwriting guidelines applicable to nonconforming loans but may have been
originated pursuant to alternative guidelines applicable to such loans. The
Sponsor will not review any Affiliated Originator mortgage loans for conformity
with the Sponsor's Guidelines set forth in the Sponsor's Originator Guide. The

Sponsor generally will review or cause to be reviewed only a limited portion of
the Mortgage Loans in any delivery of Mortgage Loans from Unaffiliated
Originators for conformity with the Sponsor's Originator Guide.
 
     The following is a brief description of the Sponsor's Guidelines set forth
in the Sponsor's Originator Guide customarily and currently employed by the
Sponsor. The Sponsor believes that these standards are consistent with those
generally used by lenders in the business of making mortgage loans based on
non-conforming credits. The underwriting process is intended to assess both the
prospective borrower's ability to repay and the adequacy of the real property as
collateral for the loan granted. The general appreciation in value of real
estate experienced in the past has been a factor in limiting the Master
Servicer's loss experience on its portfolio of one- to four-family residential
mortgage loans. However, the past pattern of appreciation in value of the real
property securing such loans has not continued, and a depreciation in value has
occurred and may continue to occur in some market areas, and may occur in
others.
 
     The Sponsor's Guidelines permit the origination and purchase of mortgage
loans with multi-tiered credit characteristics tailored to individual credit
profiles. In general, the Sponsor's Guidelines require an analysis of the equity
in the collateral, the payment history of the borrower, the borrower's ability
to repay debt, the property type, and the characteristics of the underlying
first mortgage, if any. A lower maximum CLTV is required for lower gradations of
credit quality and higher property values.
 
     The Sponsor's Guidelines permit the origination or purchase of fixed or
adjustable rate loans that either fully amortize over a period generally not to
exceed 30 years or, in the case of a balloon mortgage, generally amortize based
on a 30-year or less amortization schedule with a due date and a 'balloon'
payment due prior to the 30 year period.
 
     The homes used for collateral to secure the loans may be either owner
occupied (which includes second and vacation homes) or non-owner occupied
investor properties which, in either case are single-family residences (which
may be detached, part of a two- to four-family dwelling, a condominium unit or a
unit in a planned unit development). The Sponsor's Guidelines require that the
CLTV of a Mortgage Loan generally not exceed 85%, after taking into account the
amount of any primary mortgage insurance applicable to such Mortgage Loan.
 
                                       28

     If a senior mortgage exists, the lender may first review the senior
mortgage documentation. If it contains open end advance or negative amortization
provisions, the maximum potential senior mortgage balance may be used, although
for certain of the Sponsor's products the current balance may be used in
calculating the CLTV which determines the maximum loan amount. The Sponsor's
Guidelines do not permit the origination or purchase of loans where the senior
mortgage contains a provision pursuant to which the senior mortgagee may share
in any appreciation of the Mortgaged Property.
 
     In most cases, the value of each property proposed as security for a
mortgage loan is required to be determined by a full appraisal. A limited
appraisal of a property, conducted on a drive-by basis, may be utilized. Two

full appraisals are generally required for properties valued over $500,000.
 
     Appraisals are required to be completed by qualified professional
appraisers. The Sponsor evaluates the performance of appraisers and maintains a
current disapproved appraiser list.
 
     The Sponsor's Guidelines have provided for the origination of loans under
three general loan programs: (i) a full verification program for salaried or
self-employed borrowers, (ii) a 'lite' documentation program for borrowers who
may have income which cannot be verified by traditional methods and (iii) a
non-income verification program for self-employed borrowers only. However, the
Sponsor's Guidelines allow for certain borrowers with existing loans to
refinance such loans with either limited, or no, verification of income. The
Sponsor may also purchase pools of loans which may include some loans originated
under a non-income verification program. For the Sponsor's full verification
process, each mortgage applicant is required to provide, and the Sponsor or its
designee is required to verify, personal financial information. The applicant's
total monthly obligations (including principal and interest on each mortgage,
tax assessments, other loans, charge accounts and all other scheduled
indebtedness) generally (in the absence of countervailing considerations, such
as a lower Combined Loan-to-Value Ratio or a price adjustment) should not exceed
the applicant's ability to pay. Applicants who are salaried employees must
provide current employment information in addition to recent employment history.
The Sponsor or its designee verify this information for salaried borrowers based
on written confirmation from employers or a combination of the most recent pay
stub, the most recent W-2 tax form and telephone confirmation from the employer.
Self-employed applicants are generally required to be self-employed in the same
field for a minimum of two years. The self-employed applicant is generally
required to provide personal and business financial statements and signed copies
of complete federal income tax returns (including schedules) filed for the most
recent two years. For the Sponsor's 'lite' documentation program the borrower
must establish proof of cash flow trends to support the borrower's income. Such
proof can include business bank statements or personal bank statements. For the
Sponsor's non-income verifier program, proof of two year's history of
self-employment plus proof of current self-employed status is required. The
applicant's debt-to-income ratio is calculated based on income as certified by
the borrower on the application and must be reasonable.
 
     A credit report by an independent, nationally recognized credit reporting
agency is required reflecting the applicant's complete credit history. The
credit report should reflect all delinquencies of 30 days or more,
repossessions, judgments, foreclosures, garnishments, bankruptcies and similar
instances of adverse credit that can be discovered by a search of public
records. Verification is required to be obtained of the senior mortgage balance,
if any, the status and whether local taxes, interest, insurance and assessments
are included in the applicant's monthly payment. All taxes and assessments not
included in the payment are required to be verified as current.
 
     In connection with purchase-money loans, the Sponsor's Guidelines require
(x) (i) an acceptable source of downpayment funds, (ii) verification of the
source of the downpayment funds and (iii) adequate cash reserves or (y) adequate
equity in the collateral property.
 
     Certain laws protect loan applicants by offering them a time frame after

loan documents are signed, termed the rescission period, during which the
applicant has the right to cancel the loan. The rescission period must have
expired prior to funding a loan and may not be waived by the applicant except as
permitted by law.
 
     Unless otherwise disclosed in the related Prospectus Supplement, the
Sponsor's Guidelines generally require title insurance coverage issued by an
approved ALTA or CLTA title insurance company on each Mortgage Loan it
purchases. The Sponsor, the related Originator and/or their assignees generally
are named as the insured. Title
 
                                       29

insurance policies indicate the lien position of the mortgage loan and protect
the insured against loss if the title or lien position is not as indicated.
 
     The applicant is required to secure property insurance in an amount
sufficient to cover the new loan and any prior mortgage. If the sum of the
outstanding first mortgage, if any, and the related mortgage loan exceeds
replacement value (the cost of rebuilding the subject property, which generally
does not include land value), insurance equal to replacement value may be
accepted. The Sponsor or its designee is required to ensure that its name and
address is properly added to the 'Mortgagee Clause' of the insurance policy. In
the event the Sponsor or the related Originator's name is added to a 'Loss Payee
Clause' and the policy does not provide for written notice of policy changes or
cancellation, an endorsement adding such provision is required.
 
     Approved Guidelines.  The Sponsor may cause a Trust to acquire Mortgage
Loans underwritten pursuant to underwriting guidelines that may differ from the
Sponsor's Guidelines as set forth in the Sponsor's Originator Guide. Certain of
the Mortgage Loans will be acquired in negotiated transactions, and such
negotiated transactions may be governed by agreements ('Master Commitments')
relating to ongoing acquisitions of Mortgage Loans by the Sponsor, from
Originators who will represent that the Mortgage Loans have been originated in
accordance with underwriting guidelines agreed to by the Sponsor. Certain other
Mortgage Loans will be acquired from Originators that will represent that the
Mortgage Loans were originated pursuant to underwriting guidelines determined by
a mortgage insurance company acceptable to the Sponsor. The Sponsor will accept
a certification from such insurance company as to a Mortgage Loan's insurability
in a mortgage pool as of the date of certification as evidence of a Mortgage
Loan conforming to applicable underwriting standards. Such certifications likely
will have been issued before the purchase of the Mortgage Loan by the Sponsor.
The Sponsor only will perform random quality assurance reviews on Mortgage Loans
delivered with such certifications.
 
     The underwriting standards utilized in negotiated transactions and Master
Commitments and the underwriting standards of insurance companies may vary
substantially from the Sponsor's Guidelines. All of the underwriting guidelines
will provide an underwriter with information to evaluate either the security for
the related Mortgage Loan, which security consists primarily of the borrower's
repayment ability or the adequacy of the Mortgaged Property as collateral, or a
combination of both. Due to the variety of underwriting guidelines and review
procedures that may be applicable to the Mortgage Loans included in any Mortgage
Pool, the related Prospectus Supplement will not distinguish among the various

underwriting guidelines applicable to the Mortgage Loans nor describe any review
for compliance with applicable underwriting guidelines performed by the Sponsor.
Moreover, there can be no assurance that every Mortgage Loan was originated in
conformity with the Approved Guidelines in all material respects, or that the
quality or performance of Mortgage Loans underwritten pursuant to varying
guidelines as described above will be equivalent under all circumstances.
 
     Bulk Guidelines.  Bulk portfolios of Mortgage Loans may be originated by a
variety of Originators under several different underwriting guidelines. For bulk
portfolios which are seasoned for a period of time, the Sponsor's underwriting
review of bulk portfolios of Mortgage Loans focuses primarily on payment
histories and estimated current values based on estimated property appreciation
or depreciation and loan amortization. Mortgage Loans that conform to the
related Bulk Guidelines may not conform to the requirements of either the
Sponsor's Guidelines or the Approved Guidelines. For example, the Sponsor may
purchase Mortgage Loans in bulk portfolios with Combined Loan-to-Value Ratios in
excess of that required under the Sponsor's Guidelines, without title insurance,
or with nonconforming appraisal methods such as tax assessments. Bulk
Acquisition portfolios may be purchased servicing released or retained. If
servicing is retained, the Originator must meet certain minimum requirements, as
modified from time to time, by the Sponsor. The Sponsor generally will cause the
Mortgage Loans acquired in a Bulk Acquisition to be reunderwritten on a sample
basis. Such reunderwriting may be performed by the Sponsor, the Master Servicer
or by a third party acting at the direction of the Sponsor.
 
     Quality Control.  The Master Servicer maintains a quality control
department which generally reviews loans originated by Affiliated Originators.
The quality control department randomly selects a portion of the files for
underwriting review. The Sponsor or its Affiliated Originators also cause
appraisal reviews to be performed on a random sample of loan production.
 
     A periodic report is distributed to senior management and the production
offices describing material exceptions to underwriting and appraisal guidelines,
legal and regulatory requirements and variances based on the
 
                                       30

reverification process. Appraisers demonstrating chronic errors, omissions or
large valuation errors are removed from the approved appraiser list. Training
programs, additional audits and performance evaluations for underwriting
personnel and management are influenced by the results of the quality control
review.
 
     The Sponsor generally will cause Mortgage Loans acquired from Unaffiliated
Originators to be (i) reunderwritten for the purpose of determining whether such
Mortgage Loans were originated in accordance with the applicable underwriting
guidelines, (ii) reviewed to assess the accuracy of the appraised values, and
(iii) audited to determine the accuracy of the loan computer system as compared
to the loan files. Such process may consist of a review of all such Mortgage
Loans or may be performed on a sample basis. Such reunderwriting may be
performed by the Sponsor, the Master Servicer or a third party acting at the
direction of the Sponsor.
 
QUALIFICATIONS OF ORIGINATORS

 
     Each Originator from which a Mortgage Loan is acquired will have been
accepted by the Sponsor for participation in the Sponsor's mortgage loan
program. Certain Unaffiliated Originators ('Conduit Participants') may be
qualified to enter into agreements to sell mortgage loans to the Sponsor
pursuant to Master Commitments which provide for the periodic purchase and sale
of loans meeting certain specified requirements.
 
     Loans acquired from Unaffiliated Originators other than Conduit
Participants will be acquired on a 'spot' basis, or in connection with a Bulk
Acquisition. Unless otherwise described in the related Prospectus Supplement
with respect to certain specified Unaffiliated Originators (in which case any
remedies for breach will lie only against such Unaffiliated Originator), the
Sponsor will make directly, or will guarantee compliance with, any
representations and warranties made by any Unaffiliated Originator, with respect
to the Mortgage Loans originated by it and acquired by a Trust.
 
     All Conduit Participants must have received a satisfactory review by the
Sponsor of its operating procedures. All Unaffiliated Originators will have
delinquency and foreclosure rates monitored and maintained at levels acceptable
to the Sponsor. All Unaffiliated Originators are required to originate mortgage
loans in accordance with the applicable underwriting standards. However, with
respect to any Originator, some of the generally applicable underwriting
standards described herein and in the Sponsor's Originator Guide may be modified
or waived with respect to certain Mortgage Loans originated by such Originators.
 
     The Resolution Trust Corporation (the 'RTC') or the Federal Deposit
Insurance Corporation (the 'FDIC') (either in their respective corporate
capacities or as receiver or conservator for a depository institution) may also
be an Originator of the Mortgage Loans. The RTC and the FDIC are together
referred to as the 'Federal Corporations'. The RTC was established pursuant to
the Financial Institutions Reform, Recovery, and Enforcement Act of 1989
('FIRREA'), which was enacted in response to the financial crisis of the thrift
industry and the Federal Savings and Loan Insurance Corporation. The purpose of
FIRREA is to restore the public's confidence in the savings and loan industry in
order to ensure a viable system of affordable housing finance as well as to
improve the supervision of savings associations and promote the independence of
the FDIC. The FDIC is an independent executive agency originally established by
the Banking Act of 1933 to insure the deposits of all banks entitled to federal
deposit insurance under the Federal Reserve Act and Federal Deposit Insurance
Act. The FDIC administers the system of nationwide deposit insurance (mutual
guaranty of deposits) for United States Banks and, together with the United
States Comptroller of the Currency, regulates in areas related to the
maintenance of reserves for certain types of deposits, the maintenance of
certain financial ratios, transactions with affiliates and a broad range of
other banking practices.
 
     The Sponsor monitors the Originators and the Sub-Servicers under the
control of a Federal Corporation, as well as those Originators and Sub-Servicers
that are insolvent or in receivership or conservatorship or otherwise
financially distressed. Such Originators may not be able or permitted to
repurchase Mortgage Loans for which there has been a breach of representation
and warranty. Moreover, any such Originator may make no representations and
warranties with respect to Mortgage Loans sold by it. The Federal Corporations

(either in their respective corporate capacities or as receiver for a depository
institution) may also originate Mortgage Loans, in which event neither the
related Federal Corporation nor the depository institution for which such
Federal Corporation is acting as receiver may make representations and
warranties with respect to the Mortgage Loans that such Federal Corporation
sells, or such Federal Corporation may make only limited representations and
warranties (for example, that the related legal documents are enforceable). A
Federal Corporation may have
 
                                       31

no obligation to repurchase any Mortgage Loan for a breach of a representation
and warranty. If as a result of a breach of representation and warranty an
Originator is required to repurchase a Mortgage Loan but is not permitted or
otherwise fails to do so or if representations and warranties are not made by an
Originator, to the extent that neither the Sponsor nor any other entity has
assumed the representations and warranties or made representations and
warranties, neither the Sponsor nor that entity will be required to repurchase
such Mortgage Loan and, consequently such Mortgage Loan will remain in the
related Mortgage Pool and any related losses will be borne by the
Securityholders or by the related Credit Enhancement, if any. In addition, loans
which are purchased either directly or indirectly from a Federal Corporation may
be subject to a contract right of such Federal Corporation to repurchase such
loans under certain limited circumstances.
 
SUB-SERVICERS
 
     Each Originator of a Mortgage Loan will act as Sub-Servicer for such
Mortgage Loan pursuant to an agreement between the Master Servicer and the
Sub-Servicer (a 'Sub-Servicing Agreement') unless the servicing obligations are
released to the Master Servicer or transferred to a servicer approved by the
Master Servicer. An Affiliated Originator of a Mortgage Loan may act as the
Sub-Servicer for such Mortgage Loan unless the other related servicing
obligations are released or transferred. An Unaffiliated Originator acting as a
Sub-Servicer for the Mortgage Loans will be required to meet certain additional
standards with respect to its mortgage loan servicing portfolio, GAAP tangible
net worth and other specified qualifications.
 
REPRESENTATIONS BY ORIGINATORS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Originator will have made representations and warranties in respect of the
Mortgage Loans sold by such Originator and evidenced by a series of Securities.
Such representations and warranties generally include, among other things, that
at the time of the sale by the Originator to the Sponsor of each Mortgage Loan:
(i) the information with respect to each Mortgage Loan set forth in the
Schedules of Mortgage Loans is true and correct as of the related Cut-Off Date;
(ii) each Mortgage Loan being transferred to the Trust which is a REMIC is a
qualified mortgage under the REMIC provisions of the Code and is a Mortgage;
(iii) each Mortgaged Property is improved by a single (one- to four-) family
residential dwelling or a multi-family structure, which may include condominiums
and townhouses; (iv) each Mortgage Loan had, at the time of origination, either
an attorney's certification of title or a title search or title policy; (v) as
of the related Cut-Off Date each Mortgage Loan is secured by a valid and

subsisting lien of record on the Mortgaged Property having the priority
indicated on the related Schedule of Mortgage Loans subject in all cases to
exceptions to title set forth in the title insurance policy, if any, with
respect to the related Mortgage Loan; (vi) each Originator held good and
indefeasible title to, and was the sole owner of, each Mortgage Loan conveyed by
such Originator; and (vii) each Mortgage Loan was originated in accordance with
law and is the valid, legal and binding obligation of the related Mortgagor.
 
     Unless otherwise described in the related Prospectus Supplement, all of the
representations and warranties of an Originator in respect of a Mortgage Loan
will be made as of the date on which such Originator sells the Mortgage Loan to
the Sponsor; the date as of which such representations and warranties are made
thus may be a date prior to the date of the issuance of the related series of
Securities. A substantial period of time may elapse between the date as of which
the representations and warranties are made and the later date of issuance of
the related series of Securities.
 
     The Sponsor will assign to the Trustee for the benefit of the holders of
the related series of Securities all of its right, title and interest in each
agreement by which it acquires a Mortgage Loan from an Originator insofar as
such agreement relates to the representations and warranties made by an
Originator in respect of such Mortgage Loan and any remedies provided for breach
of such representations and warranties. If an Originator cannot cure a breach of
any representation or warranty made by it in respect of a Mortgage Loan that
materially and adversely affects the interests of the Securityholders in such
Mortgage Loan within a time period specified in the related Pooling and
Servicing Agreement, such Originator and/or the Sponsor will be obligated to
purchase from the related Trust such Mortgage Loan at a price (the 'Loan
Purchase Price') set forth in the related Pooling and Servicing Agreement which
Loan Purchase Price will be equal to the principal balance thereof as of the
date of purchase plus one month's interest at the Mortgage Rate less the amount,
expressed as a percentage per annum, payable in respect of master servicing
compensation or subservicing compensation, as applicable, and the
 
                                       32

Originator's Retained Yield, if any, together with, without duplication, the
aggregate amount of all delinquent interest, if any.
 
     Unless otherwise specified in the related Prospectus Supplement, as to any
such Mortgage Loan required to be purchased by an Originator and/or the Sponsor,
as provided above, rather than repurchase the Mortgage Loan, the Master Servicer
may, at its sole option, remove such Mortgage Loan (a 'Deleted Mortgage Loan')
from the related Trust and cause the Sponsor to substitute in its place another
Mortgage Loan of like kind (a 'Qualified Replacement Mortgage' as such term is
defined in the related Pooling and Servicing Agreement). With respect to a Trust
for which a REMIC election is to be made, except as otherwise provided in the
Prospectus Supplement relating to a series of Securities, such substitution of a
defective Mortgage Loan must be effected within two years of the date of the
initial issuance of the Securities, and may not be made if such substitution
would cause the Trust to not qualify as a REMIC or result in a prohibited
transaction tax under the Code. Unless otherwise specified in the related
Prospectus Supplement or Pooling and Servicing Agreement, an Unaffiliated
Originator generally will have no option to substitute for a Mortgage Loan that

it is obligated to repurchase in connection with a breach of a representation
and warranty.
 
     The Master Servicer will be required under the applicable Pooling and
Servicing Agreement to enforce such purchase or substitution obligations for the
benefit of the Trustee and the Securityholders, following the practices it would
employ in its good faith business judgment if it were the owner of such Mortgage
Loan; provided, however, that this purchase or substitution obligation will in
no event become an obligation of the Master Servicer in the event the Originator
fails to honor such obligation. If the Originator fails to repurchase or
substitute a loan and no breach of the Sponsor's representations has occurred,
the Originator's purchase obligation will in no event become an obligation of
the Sponsor. Unless otherwise specified in the related Prospectus Supplement,
the foregoing will constitute the sole remedy available to Securityholders or
the Trustee for a breach of representation by an Originator in its capacity as a
seller of Mortgage Loans to the Sponsor.
 
     Unless otherwise described in the related Prospectus Supplement with
respect to certain Unaffiliated Originators (in which case any remedies for
breach will lie only against such Unaffiliated Originator), the Sponsor will
make directly, or will guarantee compliance with, any representations and
warranties made by any Unaffiliated Originator with respect to the Mortgage
Loans originated or purchased by it and acquired by a Trust.
 
     Notwithstanding the foregoing with respect to any Originator that requests
the Master Servicer's consent to the transfer of sub-servicing rights relating
to any Mortgage Loans to a successor servicer, the Master Servicer may release
such Originator from liability, under its representations and warranties
described above, upon the assumption by such successor servicer of the
Originator's liability for such representations and warranties as of the date
they were made. In that event, the Master Servicer's rights under the instrument
by which such successor servicer assumes the Originator's liability will be
assigned to the Trustee, and such successor servicer shall be deemed to be the
'Originator' for purposes of the foregoing provisions.
 
SUB-SERVICING BY ORIGINATORS
 
     Each Originator of a Mortgage Loan will act as the Sub-Servicer for such
Mortgage Loan pursuant to a Sub-Servicing Agreement unless servicing is released
to the Master Servicer or has been transferred to a servicer approved by the
Master Servicer. The Master Servicer may, in turn, assign such sub-servicing to
designated sub-servicers that will be qualified Originators and may include
affiliates of the Sponsor. While such a Sub-Servicing Agreement will be a
contract solely between the Master Servicer and the Sub-Servicer, the Pooling
and Servicing Agreement pursuant to which a series of Securities is issued will
provide that, if for any reason the Master Servicer for such series of
Securities is no longer the master servicer of the related Mortgage Loans, the
Trustee or any successor Master Servicer must recognize the Sub-Servicer's
rights and obligations under such Sub-Servicing Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, with the
approval of the Master Servicer, a Sub-Servicer may delegate its servicing
obligations to third-party servicers, but such Sub-Servicer will remain
obligated under the related Sub-Servicing Agreement. Each Sub-Servicer will be

required to perform the customary functions of a servicer, including collection
of payments from Mortgagors and remittance of such collections to the Master
Servicer; maintenance of hazard insurance and filing and settlement of claims
thereunder, subject in certain cases to the right of the Master Servicer to
approve in advance any such settlement;
 
                                       33

maintenance of escrow or impound accounts of Mortgagors for payment of taxes,
insurance and other items required to be paid by the Mortgagor pursuant to the
Mortgage Loan; processing of assumptions or substitutions; attempting to cure
delinquencies; supervising foreclosures; inspecting and managing Mortgaged
Properties under certain circumstances; and maintaining accounting records
relating to the Mortgage Loans. A Sub-Servicer also may be obligated to make
advances to the Master Servicer in respect of delinquent installments of
principal and/or interest (net of any sub-servicing or other compensation) on
Mortgage Loans, as described more fully under 'Description of the
Securities--Advances,' and in respect of certain taxes and insurance premiums
not paid on a timely basis by Mortgagors. A Sub-Servicer may also be obligated
to deposit amounts in respect of Compensating Interest to the related Principal
and Interest Account in connection with prepayments of principal received and
applied to reduce the outstanding principal balance of a Mortgage Loan. No
assurance can be given that the Sub-Servicers will carry out their advance or
payment obligations, if any, with respect to the Mortgage Loans. Unless
otherwise specified in the related Prospectus Supplement, a Sub-Servicer may
transfer its servicing obligations to another entity that has been approved for
participation in the Sponsor's loan purchase programs, but only with the prior
written approval of the Master Servicer.
 
     As compensation for its servicing duties, the Sub-Servicer may be entitled
to a Base Servicing Fee. The Sub-Servicer may also be entitled to collect and
retain, as part of its servicing compensation, any late charges or prepayment
penalties provided in the Mortgage Note or related instruments. The Sub-Servicer
will be entitled to reimbursement for certain expenditures that it makes,
generally to the same extent that the Master Servicer would be reimbursed under
the applicable Pooling and Servicing Agreement. See 'The Pooling and Servicing
Agreement--Servicing and Other Compensation and Payment of Expenses;
Originator's Retained Yield.'
 
     Each Sub-Servicer will be required to agree to indemnify the Master
Servicer for any liability or obligation sustained by the Master Servicer in
connection with any act or failure to act by the Sub-Servicer in its servicing
capacity. Each Sub-Servicer is required to maintain a fidelity bond and an
errors and omission policy with respect to its officers, employees and other
persons acting on its behalf or on behalf of the Master Servicer.
 
     Each Sub-Servicer will be required to service each Mortgage Loan pursuant
to the terms of the Sub-Servicing Agreement for the entire term of such Mortgage
Loan, unless the Sub-Servicing Agreement is terminated earlier by the Master
Servicer or unless servicing is released to the Master Servicer. The Master
Servicer generally may terminate a Sub-Servicing Agreement immediately upon the
giving of notice upon certain stated events, including the violation of such
Sub-Servicing Agreement by the Sub-Servicer, or following a specified period
after notice to the Sub-Servicer without cause upon payment of an amount equal

to a specified termination fee calculated as a specified percentage of the
aggregate outstanding principal balance of all mortgage loans, including the
Mortgage Loans serviced by such Sub-Servicer pursuant to a Sub-Servicing
Agreement and certain transfer fees.
 
     The Master Servicer may agree with a Sub-Servicer to amend a Sub-Servicing
Agreement. Upon termination of a Sub-Servicing Agreement, the Master Servicer
may act as servicer of the related Mortgage Loans or enter into one or more new
Sub-Servicing Agreements. If the Master Servicer acts as servicer, it will not
assume liability for the representations and warranties of the Sub-Servicer that
it replaces. If the Master Servicer enters into a new Sub-Servicing Agreement,
each new Sub-Servicer either must be an Originator, meet the standards for
becoming an Originator or have such servicing experience that is otherwise
satisfactory to the Master Servicer. The Master Servicer may make reasonable
efforts to have the new Sub-Servicer assume liability for the representations
and warranties of the terminated Sub-Servicer, but no assurance can be given
that such an assumption will occur and, in any event, if the new Sub-Servicer is
an affiliate of the Master Servicer, the liability for such representations and
warranties will not be assumed by such new Sub-Servicer. In the event of such an
assumption, the Master Servicer may in the exercise of its business judgment
release the terminated Sub-Servicer from liability in respect of such
representations and warranties. Any amendments to a Sub-Servicing Agreement or
to a new Sub-Servicing Agreement may contain provisions different from those
described above that are in effect in the original Sub-Servicing Agreements.
However, the Pooling and Servicing Agreement for each Trust Estate will provide
that any such amendment or new agreement may not be inconsistent with such
Pooling and Servicing Agreement to the extent that it would materially and
adversely affect the interests of the Securityholders.
 
                                       34

                         DESCRIPTION OF THE SECURITIES
 
GENERAL
 
     The Securities will be issued in series. Each series of Securities (or, in
certain instances, two or more series of Securities) will be issued pursuant to
a Pooling and Servicing Agreement. The following summaries (together with
additional summaries under 'The Pooling and Servicing Agreement' below) describe
all material terms and provisions relating to the Securities common to each
Pooling and Servicing Agreement. The summaries do not purport to be complete and
are subject to, and are qualified in their entirety by reference to, all of the
provisions of the Pooling and Servicing Agreement for the related Trust and the
related Prospectus Supplement.
 
     The Securities will consist of two basic types: (i) Securities of the
fixed-income type ('Fixed-Income Securities') and (ii) Securities of the equity
participation type ('Equity Securities'). No Class of Equity Securities will be
offered pursuant to this Prospectus or any Prospectus Supplement related hereto.
Fixed-Income Securities generally will be styled as debt instruments, having a
principal balance and a specified interest rate ('Interest Rate'). Fixed-Income
Securities may be either beneficial ownership interests in the related Mortgage
Loans held by the related Trust, or may represent debt secured by such Mortgage
Loans. Each series or class of Fixed-Income Securities may have a different

Interest Rate, which may be a fixed, variable or adjustable Interest Rate. The
related Prospectus Supplement will specify the Interest Rate for each series or
class of Fixed-Income 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 of Fixed-Income Securities ('Strip
Securities') entitled to (i) principal distributions, with disproportionate,
nominal or no interest distributions, or (ii) interest distributions, with
disproportionate, nominal or no principal distributions. In addition, a series
may include two or more classes of Fixed-Income Securities that differ as to
timing, sequential order, priority of payment, Interest Rate or amount of
distributions of principal or interest or both, or as to which 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 Mortgage Pool, which series
may include one or more classes of Fixed-Income Securities ('Accrual
Securities'), as to which certain accrued interest will not be distributed but
rather will be added to the principal balance (or nominal principal balance in
the case of Accrual Securities which are also Strip Securities) thereof on each
Payment Date, as hereinafter defined and in the manner described in the related
Prospectus Supplement.
 
     If so provided in the related Prospectus Supplement, a series of Securities
may include one or more classes of Fixed-Income Securities (collectively, the
'Senior Securities') that are senior to one or more classes of Fixed-Income
Securities (collectively, the 'Subordinate Securities') in respect of certain
distributions of principal and interest and allocations of losses on Mortgage
Loans. In addition, certain classes of Senior (or Subordinate) Securities may be
senior to other classes of Senior (or Subordinate) Securities in respect of such
distributions or losses.
 
     Equity Securities will represent the right to receive the proceeds of the
related Trust Estate after all required payments have been made to the
Securityholders of the related Fixed-Income Securities (both Senior Securities
and Subordinate Securities), and following any required deposits to any reserve
account that may be established for the benefit of the Fixed-Income Securities.
Equity Securities may constitute what are commonly referred to as the 'residual
interest,' 'seller's interest' or the 'general partnership interest,' depending
upon the treatment of the related Trust for federal income tax purposes. As
distinguished from the Fixed-Income Securities, the Equity Securities will not
be styled as having principal and interest components. Any losses suffered by
the related Trust first will be absorbed by the related class of Equity
Securities, as described herein and in the related Prospectus Supplement.
 
     No Class of Equity Securities will be offered pursuant to this Prospectus
or any Prospectus Supplement related hereto. Equity Securities may be offered on
a private placement basis or pursuant to a separate Registration Statement to be
filed by the Sponsor. In addition, the Sponsor and its affiliates may initially
or permanently hold any Equity Securities issued by any Trust.
 
     General Payment Terms of Securities.  As provided in the related Pooling
and Servicing Agreement and as described in the related Prospectus Supplement,
Securityholders will be entitled to receive payments on their
 

                                       35

Securities on specified dates ('Payment Dates'). Payment Dates with respect to
Fixed-Income Securities will occur monthly, quarterly or semi-annually, as
described in the related Prospectus Supplement; Payment Dates with respect to
Equity Securities will occur as described in the related Prospectus Supplement.
 
     The related Prospectus Supplement will describe a date (the 'Record Date')
preceding such Payment Date, as of which the Trustee or its paying agent will
fix the identity of the Securityholders for the purpose of receiving payments on
the next succeeding Payment Date. Unless otherwise described in the related
Prospectus Supplement, the Payment Date will be the twenty-fifth day of each
month (or, in the case of quarterly-pay Securities, the twenty-fifth day of
every third month; and, in the case of semi-annually-pay Securities, the twenty-
fifth day of every sixth month) and the Record Date will be the close of
business as of the last day of the calendar month which precedes such Payment
Date.
 
     The related Prospectus Supplement and the Pooling and Servicing Agreement
will describe a period (a 'Remittance Period') antecedent to each Payment Date
(for example, in the case of monthly-pay Securities, the calendar month
preceding the month in which a Payment Date occurs or such other specified
period). Unless otherwise provided in the related Prospectus Supplement,
collections received on or with respect to the related Mortgage Loans during a
Remittance Period will be required to be remitted by the Master Servicer to the
related Trustee prior to the related Payment Date and will be used to distribute
payments to Securityholders on such Payment Date. As may be described in the
related Prospectus Supplement, the related Pooling and Servicing Agreement may
provide that all or a portion of the principal collected on or with respect to
the related Mortgage Loans may be applied by the related Trustee to the
acquisition of additional Mortgage Loans during a specified period (rather than
used to distribute payments of principal to Securityholders during such period)
with the result that the related securities possess an interest-only period,
also commonly referred to as a revolving period, which will be followed by an
amortization period. Any such interest-only or revolving period may, upon the
occurrence of certain events to be described in the related Prospectus
Supplement, terminate prior to the end of the specified period and result in the
earlier than expected amortization of the related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to
being used to distribute payments of principal to Securityholders.
 
     The result of such retention and temporary investment by the Trustee of
such principal would be to slow the amortization rate of the related Securities
relative to the amortization rate of the related Mortgage Loans, or to attempt
to match the amortization rate of the related Securities to an amortization
schedule established at the time such Securities are issued. Any such feature
applicable to any Securities may terminate upon the occurrence of events to be
described in the related Prospectus Supplement, resulting in the current funding
of principal payments to the related Securityholders and an acceleration of the
amortization of such Securities.

 
     Unless otherwise specified in the related Prospectus Supplement, neither
the Securities nor the underlying Mortgage Loans will be guaranteed or insured
by any governmental agency or instrumentality or the Sponsor, the Master
Servicer, any Sub-Servicer, any Originator or any of their affiliates.
 
     Unless otherwise specified in the Prospectus Supplement with respect to a
series, Securities of each series covered by a particular Pooling and Servicing
Agreement will evidence specified beneficial ownership interest in a separate
Trust Estate created pursuant to such Pooling and Servicing Agreement. A Trust
Estate will consist of, to the extent provided in the Pooling and Servicing
Agreement: (i) a pool of Mortgage Loans (and the related mortgage documents) or
certificates of interest or participations therein underlying a particular
series of Securities as from time to time are subject to the Pooling and
Servicing Agreement, exclusive of, if specified in the related Prospectus
Supplement, any Originator's Retained Yield or other interest retained by the
related Originator, the Sponsor or any of its affiliates with respect to each
such Mortgage Loan; (ii) certain other assets including, without limitation,
payments and collections in respect of the Mortgage Loans due, accrued or
received, as described in the related Prospectus Supplement, on and after the
related Cut-Off Date, as from time to time are identified as deposited in
respect thereof in the Principal and Interest Account and in the related
Distribution Account; (iii) property acquired by foreclosure of the Mortgage
Loans or deed in lieu of foreclosure; (iv) hazard insurance policies and primary
insurance policies, if any, and certain proceeds thereof; and (v) any
combination, as specified in the related Prospectus Supplement, of a letter of
credit, financial guaranty insurance
 
                                       36

policy, purchase obligation, mortgage pool insurance policy, special hazard
insurance policy, bankruptcy bond, reserve fund or other type of Credit
Enhancement as described under 'Description of Credit Enhancement.' To the
extent that any Trust Estate includes certificates of interest or participations
in Mortgage Loans, the related Prospectus Supplement will describe the material
terms and conditions of such certificates or participations.
 
FORM OF SECURITIES
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities of each series will be issued as physical certificates ('Physical
Certificates') in fully registered form only in the denominations specified in
the related Prospectus Supplement, and will be transferable and exchangeable at
the corporate trust office of the registrar of the Securities (the 'Security
Registrar') named in the related Prospectus Supplement. No service charge will
be made for any registration of exchange or transfer of Securities, but the
Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge.
 
     If so specified in the related Prospectus Supplement, specified classes of
a series of Securities will be issued in uncertificated book-entry form
('Book-Entry Securities'), and will be registered in the name of Cede, the
nominee of DTC. 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 ('UCC') and a
'clearing agency' registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. DTC was created to hold securities
for its participating organizations ('Participants') and facilitate the
clearance and settlement of securities transactions between Participants through
electronic book-entry changes in their accounts, thereby eliminating the need
for physical movement of certificates. Participants include securities brokers
and dealers, banks, trust companies and clearing corporations and may include
certain other organizations. Indirect access to the DTC system also is available
to others such as brokers, dealers, banks and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly ('Indirect Participant').
 
     Under a book-entry format, Securityholders that are not 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, such
Securityholders will receive all distributions of principal of and interest on
the Securities from the Trustee through DTC and its Participants. Under a
book-entry format, Securityholders will receive payments after the related
Payment Date because, while payments are required to be forwarded to Cede, as
nominee for DTC, on each such date, DTC will forward such payments to its
Participants, which thereafter will be required to forward such payments to
Indirect Participants or Securityholders. Unless and until Physical Securities
are issued, it is anticipated that the only Securityholder 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 Pooling and Servicing
Agreement. The beneficial holders of such Securities will only be permitted to
exercise the rights of Securityholders under the Pooling and Servicing Agreement
indirectly through DTC and its Participants who in turn will exercise their
rights through DTC.
 
     Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers among Participants
on whose behalf it acts with respect to the Securities and is required to
receive and transmit payments of principal of and interest on the Securities.
Participants and Indirect Participants with which Securityholders have accounts
with respect to their Securities similarly are required to make book-entry
transfers and receive and transmit such payments on behalf of their respective
Securityholders. Accordingly, although Securityholders will not possess
Securities, the rules provide a mechanism by which Securityholders will receive
distributions and will be able to transfer their interests.
 
     Unless and until Physical Certificates are issued, Securityholders who are
not Participants may transfer ownership of Securities only through Participants
by instructing such Participants to transfer Securities, by book-entry transfer,
through DTC for the account of the purchasers of such Securities, which account
is maintained with their respective Participants. Under the 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.
 

                                       37

     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a
Securityholder to pledge Securities to persons or entities that do not
participate in the DTC system, or otherwise take actions in respect of such
Securities may be limited due to the lack of a Physical Certificate for such
Securities.
 
     DTC in general advises that it will take any action permitted to be taken
by a Securityholder under a Pooling and Servicing Agreement only at the
direction of one or more Participants to whose account with DTC the related
Securities are credited. Additionally, DTC in general advises that it will take
such actions with respect to specified percentages of the Securityholders only
at the direction of and on behalf of Participants whose holdings include current
principal amounts of outstanding Securities that satisfy such specified
percentages. DTC may take conflicting actions with respect to other current
principal amounts of outstanding Securities to the extent that such actions are
taken on behalf of Participants whose holdings include such current principal
amounts of outstanding Securities.
 
     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 ('Physical Certificates'), rather than to DTC or its nominee only
under the events specified in the related Pooling and Servicing Agreement and
described in the related Prospectus Supplement. Upon the occurrence of any of
the events specified in the related Pooling and Servicing Agreement and the
Prospectus Supplement, DTC will be required to notify all Participants of the
availability through DTC of Physical Certificates. Upon surrender by DTC of the
securities representing the Securities and instruction for reregistration, the
Trustee will issue the Securities in the form of Physical Certificates, and
thereafter the Trustee will recognize the holders of such 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 herein and in the Pooling and Servicing Agreement.
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 such Securities on the final Payment Date at such
office or agency as is specified in the notice of final payment to
Securityholders.
 
ASSIGNMENT OF MORTGAGE LOANS
 
     At the time of issuance of a series of Securities, the Sponsor will cause
the Mortgage Loans being included in the related Trust Estate to be assigned to
the Trustee together with, unless otherwise specified in the related Prospectus
Supplement, all payments and collections in respect of the Mortgage Loans due,
accrued or received, as described in the related Prospectus Supplement on or
after the related Cut-Off Date. If specified in the related Prospectus
Supplement, the Sponsor or any of its affiliates may retain the Originator's
Retained Yield, if any, for itself or transfer the same to others. The Trustee
will, concurrently with such assignment, deliver a series of Securities to the
Sponsor in exchange for the Mortgage Loans. Each Mortgage Loan will be
identified in a schedule appearing as an exhibit to the related Pooling and

Servicing Agreement. Such schedule will include, among other things, information
as to the principal balance of each Mortgage Loan as of the Cut-Off Date, as
well as information regarding the Mortgage Rate, the currently scheduled monthly
payment of principal and interest and the maturity of the Mortgage Note.
 
     In connection with the establishment of certain Trusts the Sponsor may
first transfer the related Trust Estate to the Transferor and the Transferor
will then transfer such Trust Estate to the related Trust. The use of the
Transferor will not affect the obligations of the Sponsor with respect to the
related Trust or the related Securities. If the Transferor is to be involved in
a particular offering the related Prospectus Supplement will describe its role
in such offering; for purposes of this Prospectus the role of the Transferor is
subsumed in the role of the Sponsor.
 
     The related Prospectus Supplement will describe any applicable requirements
relating to the delivery of documents, such as the related Notes, and the
preparation and/or filing of transfer documentation, such as assignments of
Mortgage, in connection with the establishment of the related Trust. To the
extent that the ratings, if any, then assigned to the unsecured debt of the
Sponsor or of the Sponsor's ultimate corporate parent are satisfactory to the
Rating Agencies, all or any portion of such document delivery requirements
and/or transfer document preparation and filing requirements may be waived, all
as to be described in the related Prospectus Supplement.
 
                                       38

     A typical provision relating to document delivery requirements would
provide that the Sponsor deliver to the Trustee a file consisting of (i) the
original Notes or certified copies thereof, endorsed by the Originator thereof
in blank or to the order of the holder, (ii) originals of all intervening
assignments, showing a complete chain of title from origination to the
applicable Originators, if any, including warehousing assignments, with evidence
of recording thereon, (iii) originals of all assumption and modification
agreements, if any, and, unless such Mortgage Loan is covered by a counsel's
opinion as described in the next paragraph, (iv) either: (a) the original
Mortgage, with evidence of recording thereon, (b) a true and accurate copy of
the Mortgage where the original has been transmitted for recording, until such
time as the original is returned by the public recording office or (c) a copy of
the Mortgage certified by the public recording office in those instances where
the original recorded Mortgage has been lost. To the extent that such a file
containing all or a portion of such items has been delivered to the Trustee, the
Trustee will generally be required, for the benefit of the Securityholders, to
review each such file within a specified period, generally not exceeding 90
days, to ascertain that all required documents (or certified copies of
documents) have been executed and received.
 
     A typical provision relating to the preparation and filing of transfer
documentation would require the Originators to cause to be prepared and
recorded, within a specified period, generally not exceeding 75 business days of
the execution and delivery of the applicable Pooling and Servicing Agreement
(or, if original recording information is unavailable, within such later period
as is permitted by the Pooling and Servicing Agreement) assignments of the
Mortgages from the Originators to the Trustee, in the appropriate jurisdictions
in which such recordation is necessary to perfect the lien thereof as against

creditors of or purchasers from the Originators, to the Trustee; provided,
however, that if the Originators furnish to the Trustee and to the Certificate
Insurer an opinion of counsel to the effect that no such recording is necessary
to perfect the Trustee's interests in the Mortgages with respect to any of the
jurisdictions in which the related Mortgaged Properties are located, then such
recording will not be required with respect to such jurisdictions or at the
election of the Certificate Insurer, any jurisdiction.
 
     Unless otherwise specified in the related Prospectus Supplement, if any
such document is found to be missing or defective in any material respect, the
Trustee (or such custodian) shall promptly so notify the Sponsor, which shall
notify the related Sub-Servicer or Originator, as the case may be. If the
Sub-Servicer or Originator does not cure the omission or defect within a
specified period, generally not exceeding 60 days after notice is given to the
Sponsor, the Sub-Servicer or Originator, as the case may be, will be obligated
to purchase on the next succeeding Remittance Date the related Mortgage Loan
from the Trustee at its Loan Purchase Price (or, if specified in the related
Prospectus Supplement, will be permitted to substitute for such Mortgage Loan
under the conditions specified in the related Prospectus Supplement). The Master
Servicer will be obligated to enforce this obligation of the Sub-Servicer or
Originator, as the case may be, to the extent described above under 'Mortgage
Loan Program--Representations by Originators.' Unless otherwise specified in the
related Prospectus Supplement, neither the Master Servicer nor the Sponsor will,
however, be obligated to purchase or substitute for such Mortgage Loan if the
Sub-Servicer or Originator, as the case may be, defaults on its obligation to do
so, and there can be no assurance that a Sub-Servicer or Originator, as the case
may be, will carry out any such obligation. Unless otherwise specified in the
related Prospectus Supplement, such purchase obligation constitutes the sole
remedy available to the Securityholders or the Trustee for omission of, or a
material defect in, a constituent document.
 
     The Trustee will be authorized at any time to appoint a custodian pursuant
to a custodial agreement to maintain possession of and, if applicable, to review
the documents relating to the Mortgage Loans as the agent of the Trustee. The
identity of any such custodian to be appointed on the date of initial issuance
of the Securities will be set forth in the related Prospectus Supplement.
 
     Pursuant to each Pooling and Servicing Agreement, the Master Servicer,
either directly or through Sub-Servicers, will service and administer the
Mortgage Loans assigned to the Trustee as more fully set forth below.
 
FORWARD COMMITMENTS; PRE-FUNDING
 
     A Trust may enter into an agreement (each, a 'Forward Purchase Agreement')
with the Sponsor whereby the Sponsor will agree to transfer additional Mortgage
Loans to such Trust following the date on which such Trust is established and
the related Securities are issued. The Trust may enter into Forward Purchase
Agreements to permit the acquisition of additional Mortgage Loans (the
'Subsequent Mortgage Loans') that could not be
 
                                       39

delivered by the Sponsor or have not formally completed the origination process,
in each case prior to the date on which the Securities are delivered to the

Securityholders (the 'Closing Date'). Any Forward Purchase Agreement will
require that any Mortgage Loans so transferred to a Trust conform to the
requirements specified in such Forward Purchase Agreement. In addition, the
Forward Purchase Agreement states that the Depositor shall only transfer the
Subsequent Mortgage Loans upon the satisfaction of certain conditions including
that the Depositor shall have delivered to the Certificate Insurer, the Rating
Agencies and the Trustee opinions of counsel (including bankruptcy, corporate
and tax opinions) with respect to the transfer of the Subsequent Mortgage Loans.
 
     If a Forward Purchase Agreement is to be utilized, and unless otherwise
specified in the related Prospectus Supplement, the related Trustee will be
required to deposit in a segregated account (each, a 'Pre-Funding Account') up
to 100% of the net proceeds received by the Trustee in connection with the sale
of one or more classes of Securities of the related series; the additional
Mortgage Loans will be transferred to the related Trust in exchange for money
released to the Sponsor from the related Pre-Funding Account. Each Forward
Purchase Agreement will set a specified period (the 'Funding Period') during
which any such transfers must occur; for a Trust which elects federal income
treatment as a REMIC or as a grantor trust, the related Funding Period will be
limited to three months from the date such Trust is established; for a Trust
which is treated as a mere security device for federal income tax purposes, the
related Funding Period will be limited to nine months from the date such Trust
is established. The Forward Purchase Agreement or the related Pooling and
Servicing Agreement will require that, if all moneys originally deposited to
such Pre-Funding Account are not so used by the end of the related Funding
Period, then any remaining moneys will be applied as a mandatory prepayment of
the related class or classes of Securities as specified in the related
Prospectus Supplement.
 
     During the Funding Period, the moneys deposited to the Pre-Funding Account
will either (i) be held uninvested or (ii) will be invested in cash-equivalent
investments that are rated in one of the four highest rating categories by at
least one nationally recognized statistical rating organization and that will
either mature prior to the end of the Funding Period, or will be drawable on
demand and in any event, will not constitute the type of investment that would
require registration of the related Trust as an 'investment company' under the
Investment Company Act of 1940, as amended. On payment dates that occur during
the Funding Period, the Trustee will transfer any earnings on the moneys in the
Pre-Funding Account to the Certificate Account for distribution to the
Certificateholders.
 
     The Pre-Funding Account will be maintained by the Trustee, which must be a
bank having combined capital and surplus, generally, of a least $100,000,000,
long-term, unsecured debt rated at least investment grade and a long-term
deposit rating of at least investment grade.
 
PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO DISTRIBUTION ACCOUNT
 
     Each Sub-Servicer servicing a Mortgage Loan pursuant to a Sub-Servicing
Agreement will establish and maintain an account (the 'Sub-Servicing Account')
which generally meets the requirements set forth in the Sponsor's Originator
Guide from time to time, and is otherwise acceptable to the Master Servicer. A
Sub-Servicing Account must be established with a Federal Home Loan Bank or with
a depository institution (including the Sub-Servicer itself) whose accounts are

insured by the National Credit Union Share Insurance Fund or the FDIC, provided
that any such depository institution must meet certain minimum rating criteria
set forth in the Sponsor's Originator Guide. Except as otherwise permitted by
the applicable Rating Agencies, a Sub-Servicing Account must be segregated and
may not be established as a general ledger account.
 
     A Sub-Servicer is required to deposit into its Sub-Servicing Account on a
daily basis all amounts described above under 'Mortgage Loan
Program--Sub-Servicing by Originators' that are received by it in respect of the
Mortgage Loans, less its servicing or other compensation. On or before the date
specified in the Sub-Servicing Agreement (which date may be no later than the
business day prior to the Determination Date referred to below or, if such day
is not a business day, the preceding business day), the Sub-Servicer must remit
or cause to be remitted to the Master Servicer all funds held in the
Sub-Servicing Account with respect to Mortgage Loans that are required to be so
remitted. A Sub-Servicer may also be required to make such Servicing Advances
and Delinquency Advances and to pay Compensating Interest as set forth in the
related Sub-Servicing Agreement.
 
     The Master Servicer will deposit or will cause to be deposited into the
Principal and Interest Account on a daily basis certain payments and collections
due, accrued or received, as described in the related Prospectus
 
                                       40

Supplement on or after to the Cut-Off Date, as specifically set forth in the
related Pooling and Servicing Agreement, such as the following except as
otherwise provided therein:
 
          (i) all payments on account of principal, including principal payments
     received in advance of the date on which the related monthly payment is due
     (the 'Due Date') ('Principal Prepayments'), on the Mortgage Loans
     comprising a Trust Estate;
 
          (ii) all payments on account of interest on the Mortgage Loans
     comprising such Trust Estate, net of the portion of each payment thereof
     retained by the Sub-Servicer, if any, as its servicing or other
     compensation;
 
          (iii) all amounts (net of unreimbursed liquidation expenses and
     insured expenses incurred, and unreimbursed advances made, by the related
     Sub-Servicer) received and retained, if any, in connection with the
     liquidation of any defaulted Mortgage Loan, by foreclosure, deed in lieu of
     foreclosure or otherwise ('Liquidation Proceeds'), including all proceeds
     of any special hazard insurance policy, bankruptcy bond, mortgage pool
     insurance policy, financial guaranty insurance policy and any title, hazard
     or other insurance policy covering any Mortgage Loan in such Mortgage Pool
     (together with any payments under any letter of credit, 'Insurance
     Proceeds') or proceeds from any alternative arrangements established in
     lieu of any such insurance and described in the applicable Prospectus
     Supplement, other than proceeds to be applied to the restoration of the
     related property or released to the Mortgagor in accordance with the Master
     Servicer's normal servicing procedures (such amounts, net of related
     unreimbursed expenses and advances of the Master Servicer, 'Net Liquidation

     Proceeds');
 
          (iv) any Buydown Funds (and, if applicable, investment earnings
     thereon) required to be paid to Securityholders, as described below;
 
          (v) all proceeds of any Mortgage Loan in such Trust Estate purchased
     (or, in the case of a substitution, certain amounts representing a
     principal adjustment) by the Master Servicer, the Sponsor, any Sub-Servicer
     or Originator or any other person pursuant to the terms of the Pooling and
     Servicing Agreement. See 'Mortgage Loan Program--Representations by
     Originators,' '--Assignment of Mortgage Loans' above;
 
          (vi) any amounts required to be deposited by the Master Servicer in
     connection with losses realized on investments of funds held in the
     Principal and Interest Account, as described below;
 
          (vii) any amounts required to be deposited in connection with the
     liquidation of the related Trust; and
 
          (viii) any amounts required to be transferred from the Distribution
     Account to the Principal and Interest Account.
 
     In addition to the Principal and Interest Account, the Sponsor shall cause
to be established and the Trustee will maintain, at the corporate trust office
of the Trustee, in the name of the Trust for the benefit of the holders of each
series of Securities, an account for the disbursement of payments on the
Mortgage Loans evidenced by each series of Securities (the 'Distribution
Account'). The Principal and Interest Account and the Distribution Account each
must be maintained with a Designated Depository Institution. A 'Designated
Depository Institution' is an institution whose deposits are insured by the Bank
Insurance Fund or the Savings Association Insurance Fund of the FDIC, the
long-term deposits of which have a rating satisfactory to the Rating Agencies
and the related Credit Enhancer, if any, and which is any of the following: (i)
a federal savings and loan association duly organized, validly existing and in
good standing under the federal banking laws, (ii) an institution duly
organized, validly existing and in good standing under the applicable banking
laws of any state, (iii) a national banking association duly organized, validly
existing and in good standing under the federal banking laws, (iv) a principal
subsidiary of a bank holding company, or (v) approved in writing by the related
Credit Enhancer, if any, each Rating Agency and, in each case acting or
designated by the Master Servicer as the depository institution for the
Principal and Interest Account; provided, however, that any such institution or
association will generally be required to have combined capital, surplus and
undivided profits of at least $100,000,000. Notwithstanding the foregoing, the
Principal and Interest Account may be held by an institution otherwise meeting
the preceding requirements except that the only applicable rating requirement
shall be that the unsecured and uncollateralized debt obligations thereof shall
be rated at a level satisfactory to one or more Rating Agencies if such
institution has trust powers and the Principal and Interest Account is held by
such institution in its trust capacity and not in its commercial capacity. The
Distribution Account, the Principal and Interest Account and other accounts
described in the related Prospectus Supplement are collectively referred to as
'Accounts.' All funds in the Distribution Account shall be invested and
reinvested by the Trustee for the benefit of the

 
                                       41

Securityholders and the related Credit Enhancer, if any, as directed by the
Master Servicer, in certain defined obligations set forth in the related Pooling
and Servicing Agreement ('Eligible Investments'). The Principal and Interest
Account may contain funds relating to more than one series of Securities as well
as payments received on other mortgage loans serviced or master serviced by it
that have been deposited into the Principal and Interest Account. All funds in
the Principal and Interest Account will be required to be held (i) uninvested,
up to limits insured by the FDIC or (ii) invested in Eligible Investments. The
Master Servicer will be entitled to any interest or other income or gain
realized with respect to the funds on deposit in the Principal and Interest
Account.
 
     To the extent that the ratings, if any, then assigned to the unsecured debt
of the Master Servicer or of the Master Servicer's corporate parent and
satisfactory to the Rating Agencies, the Master Servicer may be permitted to
co-mingle Mortgage Loan payments and collections with the Master Servicer's
general funds rather than required to deposit such amounts into a segregated
Principal and Interest Account.
 
     Unless otherwise specified in the related Prospectus Supplement, on the day
seven days preceding each Payment Date (the 'Remittance Date'), the Master
Servicer will withdraw from the Principal and Interest Account and remit to the
Trustee for deposit in the applicable Distribution Account, in immediately
available funds, the amount to be distributed therefrom to Securityholders on
such Payment Date. The Master Servicer will remit to the Trustee for deposit
into the Distribution Account the amount of any advances made by the Master
Servicer as described herein under '--Advances,' any amounts required to be
transferred to the Distribution Account from a Reserve Fund, as described under
'Credit Enhancement' below, any amounts required to be paid by the Master
Servicer out of its own funds due to the operation of a deductible clause in any
blanket policy maintained by the Master Servicer to cover hazard losses on the
Mortgage Loans as described under 'Hazard Insurance; Claims Thereunder--Hazard
Insurance Policies' below and any other amounts as specifically set forth in the
related Pooling and Servicing Agreement. The Trustee will cause all payments
received by it from any Credit Enhancer to be deposited in the Distribution
Account not later than the related Payment Date.
 
     Unless otherwise specified in the related Prospectus Supplement, the
portion of any payment received by the Master Servicer in respect of a Mortgage
Loan that is allocable to the Originator's Retained Yield generally will not be
deposited into the Principal and Interest Account, but will not be paid over to
the parties entitled thereto as provided in the related Pooling and Servicing
Agreement.
 
     Funds on deposit in the Principal and Interest Account attributable to
Mortgage Loans underlying a series of Securities may be invested in Eligible
Investments maturing in general not later than the business day preceding the
next Payment Date. Unless otherwise specified in the related Prospectus
Supplement, all income and gain realized from any such investment will be for
the account of the Master Servicer. Funds on deposit in the related Distribution
Account may be invested in Eligible Investments maturing, in general, no later

than the business day preceding the next Payment Date.
 
     With respect to each Buydown Mortgage Loan, the Sub-Servicer will deposit
the related Buydown Funds provided to it in a Buydown Account that will comply
with the requirements set forth herein with respect to a Sub-Servicing Account.
Unless otherwise specified in the related Prospectus Supplement, the terms of
all Buydown Mortgage Loans provide for the contribution of Buydown Funds in an
amount equal to or exceeding either (i) the total payments to be made from such
funds pursuant to the related buydown plan or (ii) if such Buydown Funds are to
be deposited on a discounted basis, that amount of Buydown Funds which, together
with investment earnings thereon at a rate as set forth in the Sponsor's
Originator Guide from time to time, will support the scheduled level of payments
due under the Buydown Mortgage Loan. Neither the Master Servicer nor the Sponsor
will be obligated to add to any such discounted Buydown Funds any of its own
funds should investment earnings prove insufficient to maintain the scheduled
level of payments. To the extent that any such insufficiency is not recoverable
from the Mortgagor or, in an appropriate case, from the related Originator or
the related Sub-Servicer, distributions to Securityholders may be affected. With
respect to each Buydown Mortgage Loan, the Sub-Servicer will withdraw from the
Buydown Account and remit to the Master Servicer on or before the date specified
in the Sub-Servicing Agreement described above the amount, if any, of the
Buydown Funds (and, if applicable, investment earnings thereon) for each Buydown
Mortgage Loan that, when added to the amount due from the Mortgagor on such
Buydown Mortgage Loan, equals the full monthly payment which would be due on the
Buydown Mortgage Loan if it were not subject to the buydown plan.
 
     If the Mortgagor on a Buydown Mortgage Loan prepays such Mortgage Loan in
its entirety during the Buydown Period, the Sub-Servicer will withdraw from the
Buydown Account and remit to the Mortgagor or such
 
                                       42

other designated party in accordance with the related buydown plan any Buydown
Funds remaining in the Buydown Account. If a prepayment by a Mortgagor during
the Buydown Period together with Buydown Funds will result in full prepayment of
a Buydown Mortgage Loan, the Sub-Servicer will generally be required to withdraw
from the Buydown Account and remit to the Master Servicer the Buydown Funds and
investment earnings thereon, if any, which together with such prepayment will
result in a prepayment in full; provided that Buydown Funds may not be available
to cover a prepayment under certain Mortgage Loan programs. Any Buydown Funds so
remitted to the Master Servicer in connection with a prepayment described in the
preceding sentence will be deemed to reduce the amount that would be required to
be paid by the Mortgagor to repay fully the related Mortgage Loan if the
Mortgage Loan were not subject to the buydown plan. Any investment earnings
remaining in the Buydown Account after prepayment or after termination of the
Buydown Period will be remitted to the related Mortgagor or such other
designated party pursuant to the agreement relating to each Buydown Mortgage
Loan (the 'Buydown Agreement'). If the Mortgagor defaults during the Buydown
Period with respect to a Buydown Mortgage Loan and the property securing such
Buydown Mortgage Loan is sold in liquidation (either by the Master Servicer, the
Primary Insurer, the insurer under the mortgage pool insurance policy (the 'Pool
Insurer') or any other insurer), the Sub-Servicer will be required to withdraw
from the Buydown Account the Buydown Funds and all investment earnings thereon,
if any, and remit the same to the Master Servicer or, if instructed by the

Master Servicer, pay the same to the primary insurer or the Pool Insurer, as the
case may be, if the Mortgaged Property is transferred to such insurer and such
insurer pays all of the loss incurred in respect of such default.
 
WITHDRAWALS FROM THE PRINCIPAL AND INTEREST ACCOUNT
 
     The Master Servicer may, from time to time, make withdrawals from the
Principal and Interest Account for certain purposes, as specifically set forth
in the related Pooling and Servicing Agreement, which generally will include the
following except as otherwise provided therein:
 
          (i) to effect the timely remittance to the Trustee for deposit to the
     Distribution Account in the amounts and in the manner provided in the
     Pooling and Servicing Agreement and described in '--Payments on Mortgage
     Loans; Deposits to Distribution Account' above;
 
          (ii) to reimburse itself or any Sub-Servicer for Delinquency Advances
     and Servicing Advances as to any Mortgaged Property, out of late payments
     or collections on the related Mortgage Loan with respect to which such
     Delinquency Advances or Servicing Advances were made;
 
          (iii) to withdraw investment earnings on amounts on deposit in the
     Principal and Interest Account;
 
          (iv) to pay the Sponsor or its assignee all amounts allocable to the
     Originator's Retained Yield out of collections or payments which represent
     interest on each Mortgage Loan (including any Mortgage Loan as to which
     title to the underlying Mortgaged Property was acquired);
 
          (v) to withdraw amounts that have been deposited in the Principal and
     Interest Account in error;
 
          (vi) to clear and terminate the Principal and Interest Account in
     connection with the termination of the Trust Estate pursuant to the Pooling
     and Servicing Agreement, as described in 'The Pooling and Servicing
     Agreement--Termination, Retirement of Securities'; and
 
          (vii) to invest in Eligible Investments.
 
DISTRIBUTIONS
 
     Beginning on the Payment Date in the month following the month (or, in the
case of quarterly-pay Securities, the third month following such month and each
third month thereafter or, in the case of semi-annually-pay Securities, the
sixth month following such month and each sixth month thereafter) in which the
Cut-Off Date occurs (or such other date as may be set forth in the related
Prospectus Supplement) for a series of Securities, distributions of principal
and interest (or, where applicable, of principal only or interest only) on each
class of Securities entitled thereto will be made either by the Trustee or a
paying agent appointed by the Trustee (the 'Paying Agent'), to the persons who
are registered as Securityholders at the close of business on the Record Date in
proportion to their respective Percentage Interests. Unless otherwise specified
in the related Prospectus Supplement, interest that accrues and is not payable
on a class of Securities will be added to the principal balance of each Security

of such class in proportion to its Percentage Interest. The undivided percentage
interest (the 'Percentage Interest') represented by a Security of a particular
class will be equal to the percentage obtained by
 
                                       43

dividing the initial principal balance or notional amount of such Security by
the aggregate initial amount or notional balance of all the Securities of such
class. Distributions will be made in immediately available funds (by wire
transfer or otherwise) to the account of a Securityholder at a bank or other
entity having appropriate facilities therefor, if such Securityholder has so
notified the Trustee or the Paying Agent, as the case may be, and the applicable
Pooling and Servicing Agreement provides for such form of payment, or by check
mailed to the address of the person entitled thereto as it appears on the
Security Register; provided, however, that the final distribution in retirement
of the Securities (other than any Book-Entry Securities) will be made only upon
presentation and surrender of the Securities at the office or agency of the
Trustee specified in the notice to Securityholders of such final distribution.
 
PRINCIPAL AND INTEREST ON THE SECURITIES
 
     The method of determining, and the amount of, distributions of principal
and interest (or, where applicable, of principal only or interest only) on a
particular series of Securities will be described in the related Prospectus
Supplement. Each class of Securities (other than certain classes of Strip
Securities) may bear interest at a different interest rate (the 'Pass-Through
Rate'), which may be a fixed or adjustable Pass-Through Rate. The related
Prospectus Supplement will specify the Pass-Through Rate for each class, or in
the case of an adjustable Pass-Through Rate, the initial Pass-Through Rate and
the method for determining the Pass-Through Rate. Unless otherwise specified in
the related Prospectus Supplement, interest on the Securities will be calculated
on the basis of a 360-day year consisting of twelve 30-day months.
 
     On each Payment Date for a series of Securities, the Trustee will
distribute or cause the Paying Agent to distribute, as the case may be, to each
holder of record on the Record Date of a class of Securities, an amount equal to
the Percentage Interest represented by the Security held by such holder
multiplied by such class' Distribution Amount. The Distribution Amount for a
class of Securities for any Payment Date will be the portion, if any, of the
principal distribution amount (as defined in the related Prospectus Supplement)
allocable to such class for such Payment Date, as described in the related
Prospectus Supplement, plus, if such class is entitled to payments of interest
on such Payment Date, the interest accrued at the applicable Pass-Through Rate
on the principal balance or notional amount of such class, as specified in the
applicable Prospectus Supplement, less (unless otherwise specified in the
Prospectus Supplement) the amount of any Deferred Interest added to the
principal balance of the Mortgage Loans and/or the outstanding balance of one or
more classes of Securities on the related Due Date and any other interest
shortfalls allocable to Securityholders which are not covered by advances or the
applicable Credit Enhancement, in each case in such amount that is allocated to
such class on the basis set forth in the Prospectus Supplement.
 
     As may be described in the related Prospectus Supplement, the related
Pooling and Servicing Agreement may provide that all or a portion of the

principal collected on or with respect to the related Mortgage Loans may be
applied by the related Trustee to the acquisition of additional Mortgage Loans
during a specified period (rather than used to fund payments of principal to
Securityholders during such period) with the result that the related securities
will possess an interest-only period, also commonly referred to as a revolving
period, which will be followed by an amortization period. Any such interest-only
or revolving period may, upon the occurrence of certain events to be described
in the related Prospectus Supplement, terminate prior to the end of the
specified period and result in the earlier than expected amortization of the
related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to
being used to fund payments of principal to Securityholders.
 
     In the case of a series of Securities that includes two or more classes of
Securities, the timing, sequential order, priority of payment or amount of
distributions in respect of principal, and any schedule or formula or other
provisions applicable to the determination thereof (including distributions
among multiple classes of Senior Securities or Subordinate Securities) of each
such class shall be as provided in the related Prospectus Supplement.
Distributions in respect of principal of any class of Securities will be made on
a pro rata basis among all of the Securities of such class.
 
     Except as otherwise provided in the related Pooling and Servicing
Agreement, on or prior to the third business day next preceding the Payment Date
(or such earlier day as shall be agreed by the related Credit
 
                                       44

Enhancer, if any, and the Trustee) of the month of distribution (the
'Determination Date'), the Trustee will determine the amounts of principal and
interest which will be passed through to Securityholders on the immediately
succeeding Payment Date. If the amount in the Distribution Account is
insufficient to cover the amount to be passed through to Securityholders, the
Trustee will be required to notify the related Credit Enhancer, if any, pursuant
to the related Pooling and Servicing Agreement for the purpose of funding such
deficiency.
 
ADVANCES
 
     Unless otherwise specified in the related Prospectus Supplement, each
Servicer will be required, not later than each Remittance Date, to deposit into
the Principal and Interest Account an amount equal to the sum of the interest
portions (net of the Servicing Fees and the Originators' Retained Yield) due,
but not collected, with respect to delinquent Mortgage Loans directly serviced
by such Servicer during the prior Remittance Period, but only if, in its good
faith business judgment, such Servicer believes that such amount will ultimately
be recovered from the related Mortgage Loan. As may be described in the related
Prospectus Supplement, such Servicer may also be required so to advance
delinquent payments of principal. Any such amounts so advanced are 'Delinquency
Advances'. The Master Servicer will be permitted to fund its payment of

Delinquency Advances on any Remittance Date from collections on any Mortgage
Loan deposited to the Principal and Interest Account subsequent to the related
Remittance Period, and will be required to deposit into the Principal and
Interest Account with respect thereto (i) collections from the Mortgagor whose
delinquency gave rise to the shortfall which resulted in such Delinquency
Advance and (ii) Net Liquidation Proceeds recovered on account of the related
Mortgage Loan to the extent of the amount of aggregate Delinquency Advances
related thereto. A Sub-Servicer will be permitted to fund its payment of
Delinquency Advances as set forth in the related Sub-Servicing Agreement.
 
     A Mortgage Loan is 'delinquent' if any payment due thereon is not made by
the close of business on the day such payment is scheduled to be due.
 
     Unless otherwise specified in the related Prospectus Supplement, on or
prior to each Remittance Date, each Servicer will be required to deposit in the
Principal and Interest Account with respect to any full prepayment received on a
Mortgage Loan directly serviced by such Servicer during the related Remittance
Period out of its own funds without any right of reimbursement therefor, an
amount equal to the difference between (x) 30 days' interest at the Mortgage
Loan's Mortgage Rate (less the related Base Servicing Fees and the Originators'
Retained Yield, if any) on the principal balance of such Mortgage Loan as of the
first day of the related Remittance Period and (y) to the extent not previously
advanced, the interest (less the Servicing Fee and the Originators' Retained
Yield, if any) paid by the Mortgagor with respect to the Mortgage Loan during
such Remittance Period (any such amount paid by such Servicer, 'Compensating
Interest'). No Servicer shall be required to pay Compensating Interest with
respect to any Remittance Period in an amount in excess of the aggregate related
Base Servicing Fees received by such Servicer with respect to all Mortgage Loans
directly serviced by such Servicer for such Remittance Period.
 
     Each Servicer will be required to pay all 'out of pocket' costs and
expenses incurred in the performance of its servicing obligations, but only to
the extent that such Servicer reasonably believes that such amounts will
increase Net Liquidation Proceeds on the related Mortgage Loan. Each such amount
so paid will constitute a 'Servicing Advance'. Such Servicer may recover
Servicing Advances to the extent permitted by the Mortgage Loans or, if not
theretofore recovered from the Mortgagor on whose behalf such Servicing Advance
was made, from Liquidation Proceeds realized upon the liquidation of the related
Mortgage Loan or, in certain cases, from excess cash flow otherwise payable to
the holders of the related Equity Securities.
 
     Notwithstanding the foregoing, if the Master Servicer exercises its option,
if any, to purchase the assets of a Trust Estate as described under 'The Pooling
and Servicing Agreement--Termination; Retirement of Securities' below, the
Master Servicer will be deemed to have been reimbursed for all related advances
previously made by it and not theretofore reimbursed to it. The Master
Servicer's obligation to make advances may be supported by Credit Enhancement as
described in the related Pooling and Servicing Agreement. In the event that the
provider of such support is downgraded by a Rating Agency rating the related
Securities or if the collateral supporting such obligation is not performing or
is removed pursuant to the terms of any agreement described in the related
Prospectus Supplement, the Securities may also be downgraded.
 
                                       45


REPORTS TO SECURITYHOLDERS
 
     With each distribution to Securityholders of a particular class the Trustee
will forward or cause to be forwarded to each holder of record of such class of
Securities a statement or statements with respect to the related Trust setting
forth the information specifically described in the related Pooling and
Servicing Agreement, which generally will include the following as applicable
except as otherwise provided therein:
 
          (i) the amount of the distribution with respect to each class of
     Securities;
 
          (ii) the amount of such distribution allocable to principal,
     separately identifying the aggregate amount of any prepayments or other
     recoveries of principal included therein;
 
          (iii) the amount of such distribution allocable to interest;
 
          (iv) the aggregate unpaid Principal Balance of the Mortgage Loans
     after giving effect to the distribution of principal on such Payment Date;
 
          (v) with respect to a series consisting of two or more classes, the
     outstanding principal balance or notional amount of each class after giving
     effect to the distribution of principal on such Payment Date;
 
          (vi) the amount of coverage under any letter of credit, mortgage pool
     insurance policy or other form of Credit Enhancement covering default risk
     as of the close of business on the applicable Determination Date and a
     description of any Credit Enhancement substituted therefor;
 
          (vii) information furnished by the Sponsor pursuant to section
     6049(d)(7)(C) of the Code and the regulations promulgated thereunder to
     assist Securityholders in computing their market discount;
 
          (viii) the total of any Substitution Amounts and any Loan Purchase
     Price amounts included in such distribution; and
 
          (ix) a number with respect to each class (the 'Pool Factor') computed
     by dividing the principal balance of all Securities in such class (after
     giving effect to any distribution of principal to be made on such Payment
     Date) by the original principal balance of the Securities of such class on
     the Closing Date.
 
     Items (i) through (iii) above shall, with respect to each class of
Securities, be presented on the basis of a certificate having a $1,000
denomination. In addition, by January 31 of each calendar year during which
Securities are outstanding, the Trustee shall furnish a report to each
Securityholder at any time during each calendar year as to the aggregate amounts
reported pursuant to (i), (ii) and (iii) with respect to the Securities for such
calendar year. If a class of Securities are in book-entry form, DTC will supply
such reports to the Securityholders in accordance with its procedures.
 
     In addition, on each Payment Date the Trustee will forward or cause to be

forwarded additional information, as of the close of business on the last day of
the prior calendar month, as more specifically described in the related Pooling
and Servicing Agreement, which generally will include the following as
applicable except as otherwise provided therein:
 
          (i) the total number of Mortgage Loans and the aggregate principal
     balances thereof, together with the number, percentage (based on the
     then-outstanding principal balances) and aggregate principal balances of
     Mortgage Loans (a) 30-59 days delinquent, (b) 60-89 days delinquent and (c)
     90 or more days delinquent;
 
          (ii) the number, percentage (based on the then-outstanding principal
     balances), aggregate Mortgage Loan balances and status of all Mortgage
     Loans in foreclosure proceedings (and whether any such Mortgage Loans are
     also included in any of the statistics described in the foregoing clause
     (i));
 
          (iii) the number, percentage (based on the then-outstanding principal
     balances) and aggregate Mortgage Loan balances of all Mortgage Loans
     relating to Mortgagors in bankruptcy proceedings (and whether any such
     Mortgage Loans are also included in any of the statistics described in the
     foregoing clause (i));
 
          (iv) the number, percentage (based on the then-outstanding principal
     balances) and aggregate Mortgage Loan balances of all Mortgage Loans
     relating to the status of any Mortgaged Properties as to which title has
     been taken in the name of, or on behalf of the Trustee (and whether any
     such Mortgage Loans are also included in any of the statistics described in
     the foregoing clause (i)); and
 
          (v) the book value of any real estate acquired through foreclosure or
     grant of a deed in lieu of foreclosure.
 
                                       46

COLLECTION AND OTHER SERVICING PROCEDURES
 
     Acting directly or through one or more Sub-Servicers as provided in the
related Pooling and Servicing Agreement, the Master Servicer, is required to
service and administer the Mortgage Loans in accordance with the Pooling and
Servicing Agreement and with reasonable care, and using that degree of skill and
attention that the Master Servicer exercises with respect to comparable mortgage
loans that it services for itself or others.
 
     The duties of the Master Servicer include collecting and posting of all
payments, responding to inquiries of Mortgagors or by federal, state or local
government authorities with respect to the Mortgage Loans, investigating
delinquencies, reporting tax information to Mortgagors in accordance with its
customary practices and accounting for collections and furnishing monthly and
annual statements to the Trustee with respect to distributions and making
Delinquency Advances and Servicing Advances to the extent described in the
related Prospectus Supplement. The Master Servicer is required to follow its
customary standards, policies and procedures in performing its duties as Master
Servicer.

 
     The Master Servicer (i) is authorized and empowered to execute and deliver,
on behalf of itself, the Securityholders and the Trustee or any of them, any and
all instruments of satisfaction or cancellation, or of partial or full release
or discharge and all other comparable instruments, with respect to the Mortgage
Loans and with respect to the related Mortgaged Properties; (ii) may consent to
any modification of the terms of any Note not expressly prohibited by the
Pooling and Servicing Agreement if the ef fect of any such modification (x) will
not materially and adversely affect the security afforded by the related
Mortgaged Property or the timing of receipt of any payments required thereunder
(in each case other than as permitted by the related Pooling and Servicing
Agreement); and (y) will not cause a Trust which is a REMIC to fail to qualify
as a REMIC.
 
     The related Pooling and Servicing Agreement will require the Master
Servicer to follow such collection procedures as it follows from time to time
with respect to mortgage loans in its servicing portfolio that are comparable to
the Mortgage Loans; provided that the Master Servicer is required always at
least to follow collection procedures that are consistent with or better than
standard industry practices. The Master Servicer may in its discretion (i) waive
any assumption fees, late payment charges, charges for checks returned for
insufficient funds, prepayment fees, if any, or the fees which may be collected
in the ordinary course of servicing the Mortgage Loans, (ii) if a Mortgagor is
in default or about to be in default because of a Mortgagor's financial
condition, arrange with the Mortgagor a schedule for the payment of delinquent
payments due on the related Mortgage Loan; provided, however, the Master
Servicer shall generally not be permitted to reschedule the payment of
delinquent payments more than one time in any twelve consecutive months with
respect to any Mortgagor or (iii) modify payments of monthly principal and
interest on any Mortgage Loan becoming subject to the terms of the Relief Act in
accordance with the Master Servicer's general policies of the comparable
mortgage loans subject to such Relief Act.
 
     When a Mortgaged Property (other than Mortgaged Property subject to an ARM
Loan) has been or is about to be conveyed by the Mortgagor, the Master Servicer
will be required, to the extent it has knowledge of such conveyance or
prospective conveyance, to exercise its rights to accelerate the maturity of the
related Mortgage Loan under any 'due-on-sale' clause contained in the related
Mortgage or Note; provided, however, that the Master Servicer will not be
required to exercise any such right if (i) the 'due-on-sale' clause, in the
reasonable belief of the Master Servicer, is not enforceable under applicable
law or (ii) the Master Servicer reasonably believes that to permit an assumption
of the Mortgage Loan would not materially and adversely affect the interests of
Securityholders or the related Credit Enhancer or jeopardize coverage under any
primary insurance policy or applicable Credit Enhancement arrangements. In such
event, the Master Servicer will be required to enter into an assumption and
modification agreement with the person to whom such Mortgaged Property has been
or is about to be conveyed, pursuant to which such person becomes liable under
the Mortgage Note and, unless prohibited by applicable law or the related
documents, the Mortgagor remains liable thereon. If the foregoing is not
permitted under applicable law, the Master Servicer will be authorized to enter
into a substitution of liability agreement with such person, pursuant to which
the original Mortgagor is released from liability and such person is substituted
as Mortgagor and becomes liable under the Mortgage Note. The assumed loan must

conform in all respects to the requirements, representations and warranties of
the Pooling and Servicing Agreement.
 
     An ARM Loan may be assumed if such ARM Loan is by its terms assumable and
if, in the reasonable judgment of the Master Servicer or the Sub-Servicer, the
proposed transferee of the related Mortgaged Property establishes its ability to
repay the loan and the security for such ARM Loan would not be impaired by the
assumption. If a Mortgagor transfers the Mortgaged Property subject to an ARM
Loan without consent, such ARM Loan may be
 
                                       47

declared due and payable. Any fee collected by the Master Servicer or
Sub-Servicer for entering into an assumption or substitution of liability
agreement will be retained by the Master Servicer or Sub-Servicer as additional
servicing compensation unless otherwise set forth in the related Prospectus
Supplement. See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Enforceability of Certain Provisions' herein.
 
     The Master Servicer will have the right under the Pooling and Servicing
Agreement to approve applications of Mortgagors seeking consent for (i) partial
releases of Mortgages, (ii) alterations and (iii) removal, demolition or
division of Mortgaged Properties. No application for consent may be approved by
the Master Servicer unless: (i) the provisions of the related Mortgage Note and
Mortgage have been complied with; (ii) the credit profile of the related
Mortgage Loan after any release is consistent with the Sponsor's Originator
Guide then applicable to such Mortgage Loan; and (iii) the lien priority of the
related Mortgage is not reduced.
 
REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
     The Master Servicer shall foreclose upon or otherwise comparably effect the
ownership of Mortgaged Properties relating to defaulted Mortgage Loans as to
which no satisfactory arrangements can be made for collection of delinquent
payments and which the Master Servicer has not purchased pursuant to the related
Pooling and Servicing Agreement (such Mortgage Loans, 'REO Property'). In
connection with such foreclosure or other conversion, the Master Servicer shall
exercise such of the rights and powers vested in it, and use the same degree of
care and skill in their exercise or use, as prudent mortgage lenders would
exercise or use under the circumstances in the conduct of their own affairs,
including, but not limited to, making Servicing Advances for the payment of
taxes, amounts due with respect to Senior Liens, and insurance premiums. Unless
otherwise provided in the related Prospectus Supplement, the Master Servicer
shall sell any REO Property within 23 months of its acquisition by the Trust.
The Pooling and Servicing Agreements generally will permit the Master Servicer
to cease further collection and foreclosure activity if the Master Servicer
reasonably determines that such further activity would not increase collections
or recoveries to be received by the related Trust with respect to the related
Mortgage Loan. In addition, any required advancing may be permitted to cease at
this point.
 
     Notwithstanding the generality of the foregoing provisions, the Master
Servicer will be required to manage, conserve, protect and operate each REO
Property for the Securityholders solely for the purpose of its prompt

disposition and sale as 'foreclosure property' within the meaning of Section
860G(a)(8) of the Code or result in the receipt by the Trust of any 'income from
non-permitted assets' within the meaning of Section 860F(a)(2)(B) of the Code or
any 'net income from foreclosure property' which is subject to taxation under
the REMIC Provisions. Pursuant to its efforts to sell such REO Property, the
Master Servicer shall either itself or through an agent selected by the Master
Servicer protect and conserve such REO Property in the same manner and to such
extent as is customary in the locality where such REO Property is located and
may, incident to its conservation and protection of the interests of the
Securityholders, rent the same, or any part thereof, as the Master Servicer
deems to be in the best interest of the Securityholders for the period prior to
the sale of such REO Property. The Master Servicer shall take into account the
existence of any hazardous substances, hazardous wastes or solid wastes, as such
terms are defined in the Comprehensive Environmental Response Compensation and
Liability Act, the Resource Conservation and Recovery Act of 1976, or other
federal, state or local environmental legislation, on a Mortgaged Property in
determining whether to foreclose upon or otherwise comparably convert the
ownership of such Mortgaged Property.
 
     The Master Servicer shall determine, with respect to each defaulted
Mortgage Loan, when it has recovered, whether through trustee's sale,
foreclosure sale or otherwise, all amounts it expects to recover from or on
account of such defaulted Mortgage Loan, whereupon such Mortgage Loan shall
become a Liquidated Mortgage Loan. A Mortgage Loan which is 'charged-off', i.e.,
as to which the Master Servicer ceases further collection and/or foreclosure
activity as a result of a determination that such further actions will not
increase collections or recoveries to be received by the related Trust is also a
'Liquidated Mortgage Loan.'
 
     If a loss is realized on a defaulted Mortgage Loan or REO Property upon the
final liquidation thereof that is not covered by any applicable form of Credit
Enhancement or other insurance, the Securityholders will bear such loss.
However, if a gain results from the final liquidation of an REO Property that is
not required by law to be remitted to the related Mortgagor, the Master Servicer
will be entitled to retain such gain as additional servicing compensation unless
the related Prospectus Supplement provides otherwise. For a description of the
Master Servicer's obligations to maintain and make claims under applicable forms
of Credit Enhancement and insurance relating to the Mortgage Loans, see
'Description of Credit Enhancement' and 'Hazard Insurance; Claims Thereunder;
Hazard Insurance Policies.'
 
                                       48




                                 SUBORDINATION
 
     A Senior/Subordinate Series of Securities will consist of one or more
classes of Senior Securities and one or more classes of Subordinate Securities,
as specified in the related Prospectus Supplement. Unless otherwise specified in
the related Prospectus Supplement, only the Senior Securities will be offered
hereby. Subordination of the Subordinate Securities of any Senior/Subordinate
Series of Securities will be effected by the following method, unless an
alternative method is specified in the related Prospectus Supplement. In
addition, certain classes of Senior (or Subordinate) Securities may be senior to
other classes of Senior (or Subordinate) Securities, as specified in the related
Prospectus Supplement, in which case the following discussion is qualified in
its entirety by reference to the related Prospectus Supplement with respect to
the various priorities and other rights as among the various classes of Senior
Securities or Subordinate Securities, as the case may be.
 
     With respect to any Senior/Subordinate Series of Securities, the total
amount available for distribution on each Payment Date, as well as the method
for allocating such amount among the various classes of Securities included in
such series, will be as set forth in the related Prospectus Supplement.
Generally, the amount available for contribution will be allocated first to
interest on the Senior Securities of such series, and then to principal of the
Senior Securities up to the amounts determined as specified in the related
Prospectus Supplement, prior to allocation to the Subordinate Securities of such
series.
 
     In the event of any Realized Losses (as defined below) on Mortgage Loans
not in excess of the limitations described below, other than Extraordinary
Losses, the rights of the Subordinate Securityholders to receive distributions
with respect to the Mortgage Loans will be subordinate to the rights of the
Senior Securityholders. With respect to any defaulted Mortgage Loan that becomes
a Liquidated Mortgage Loan, through foreclosure sale, disposition of the related
Mortgaged Property if acquired by deed in lieu of foreclosure, 'charged-off' or
otherwise, the amount of loss realized, if any (as more fully described in the
related Pooling and Servicing Agreement, a 'Realized Loss'), will equal the
portion of the stated principal balance remaining, after application of all
amounts recovered (net of amounts reimbursable to the Master Servicer for
related advances and expenses) towards interest and principal owing on the
Mortgage Loan. With respect to a Mortgage Loan the principal balance of which
has been reduced in connection with bankruptcy proceedings, the amount of such
reduction will be treated as a Realized Loss.
 
     Except as noted below, all Realized Losses will be allocated to the
Subordinate Securities of the related series, until the Principal Balance (as
defined in the related Prospectus Supplement) of such Subordinate Securities
thereof has been reduced to zero. Any additional Realized Losses will be
allocated to the Senior Securities (or, if such series includes more than one
class of Senior Securities, either on a pro-rata basis among all of the Senior
Securities in proportion to their respective outstanding Principal Balances or
as otherwise provided in the related Prospectus Supplement).
 
     With respect to certain Realized Losses resulting from physical damage to

Mortgaged Properties that are generally of the same type as are covered under a
special hazard insurance policy, the amount thereof that may be allocated to the
Subordinate Securities of the related series may be limited to an amount (the
'Special Hazard Amount') specified in the related Prospectus Supplement. See
'Description of Credit Enhancement--Special Hazard Insurance Policies.' If so,
any Special Hazard Losses in excess of the Special Hazard Amount will be
allocated among all outstanding classes of Securities of the related series,
either on a pro-rata basis in proportion to their outstanding Security Principal
Balances, regardless of whether any Subordinate Securities remain outstanding,
or as otherwise provided in the related Prospectus Supplement. The respective
amounts of other specified types of losses (including Fraud Losses and
Bankruptcy Losses) that may be borne solely by the Subordinate Securities may be
similarly limited to an amount (with respect to Fraud Losses, the 'Fraud Loss
Amount' and with respect to Bankruptcy Losses, the 'Bankruptcy Loss Amount'),
and the Subordinate Securities may provide no coverage with respect to certain
other specified types of losses, as described in the related Prospectus
Supplement, in which case such losses would be allocated on a pro-rata basis
among all outstanding classes of Securities.
 
     Any allocation of a Realized Loss (including a Special Hazard Loss) to a
Security in a Senior/Subordinate Series will be made by reducing the Security
Principal Balance thereof as of the Payment Date following the calendar month in
which such Realized Loss was incurred.
 
                                       49

     In lieu of the foregoing provisions, subordination may be effected in the
following manner, or in any other manner described in the related Prospectus
Supplement. The rights of the holders of Subordinate Securities to receive any
or a specified portion of distributions with respect to the Mortgage Loans may
be subordinated to the extent of the amount set forth in the related Prospectus
Supplement (the 'Subordinate Amount'). As specified in the related Prospectus
Supplement, the Subordinate Amount may be subject to reduction based upon the
amount of losses borne by the holders of the Subordinate Securities as a result
of such subordination, a specified schedule or such other method of reduction as
such Prospectus Supplement may specify. If so specified in the related
Prospectus Supplement, additional credit support for this form of subordination
may be provided by the establishment of a reserve fund for the benefit of the
holders of the Senior Securities (which may, if such Prospectus Supplement so
provides, initially be funded by a cash deposit by the Originator) into which
certain distributions otherwise allocable to the holders of the Subordinate
Securities may be placed; such funds would thereafter be available to cure
shortfalls in distributions to holders of the Senior Securities.
 
                       DESCRIPTION OF CREDIT ENHANCEMENT
 
   
     Unless otherwise expressly provided and described in the applicable
Prospectus Supplement, each series of Securities shall have credit support
(referred to herein as 'Credit Enhancement') comprised of one or more of the
following components. Each component will have a monetary limit and will provide
coverage with respect to Realized Losses that are (i) attributable to the
Mortgagor's failure to make any payment of principal or interest as required
under the Mortgage Note, but not including Special Hazard Losses, Extraordinary

Losses or other losses resulting from damage to a Mortgaged Property, Bankruptcy
Losses or Fraud Losses (any such loss, a 'Defaulted Mortgage Loss'); (ii) of a
type generally covered by a special hazard insurance policy (as defined below)
(any such loss, a 'Special Hazard Loss'); (iii) attributable to certain actions
which may be taken by a bankruptcy court in connection with a Mortgage Loan,
including a reduction by a bankruptcy court of the principal balance of or the
Mortgage Rate on a Mortgage Loan or an extension of its maturity (any such loss,
a 'Bankruptcy Loss'); and (iv) incurred on defaulted Mortgage Loans as to which
there was fraud in the origination of such Mortgage Loans (any such loss, a
'Fraud Loss'). Losses occasioned by war, civil insurrection, certain
governmental actions, nuclear reaction and certain other risks ('Extraordinary
Losses') will not be covered unless otherwise specified. To the extent that the
Credit Enhancement for any series of Securities is exhausted, the
Securityholders will bear all further risks of loss not otherwise insured
against.
    
 
     As set forth below and in the applicable Prospectus Supplement, Credit
Enhancement may be provided with respect to one or more classes of a series of
Securities or with respect to the Mortgage Assets in the related Trust. Credit
Enhancement may be in the form of (i) the subordination of one or more classes
of Subordinate Securities to provide credit support to one or more classes of
Senior Securities as described under 'Subordination,' (ii) the use of a mortgage
pool insurance policy, special hazard insurance policy, bankruptcy bond, reserve
fund, letter of credit, financial guaranty insurance policy, other third party
guarantees, another method of Credit Enhancement described in the related
Prospectus Supplement, or the use of a cross-support feature or
overcollateralization, or (iii) any combination of the foregoing. Unless
otherwise specified in the Prospectus Supplement, any 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
thereon. If losses occur that exceed the amount covered by Credit Enhancement or
are not covered by the Credit Enhancement, holders of one or more classes of
Securities will bear their allocable share of deficiencies. If a form of Credit
Enhancement applies to several classes of Securities, and if principal payments
equal to the aggregate principal balances of certain classes will be distributed
prior to such distributions to the classes, the classes that receive such
distributions at a later time are more likely to bear any losses that exceed the
amount covered by Credit Enhancement.
 
     The amounts and type of Credit Enhancement arrangement as well as the
provider thereof, if applicable, with respect to each series of Securities will
be set forth in the related Prospectus Supplement. To the extent provided in the
applicable Prospectus Supplement and the Pooling and Servicing Agreement, the
Credit Enhancement arrangements may be periodically modified, reduced and
substituted for based on the aggregate outstanding principal balance of the
Mortgage Loans covered thereby. See 'Description of Credit
Enhancement--Reduction or Substitution of Credit Enhancement.' If specified in
the applicable Prospectus Supplement, Credit Enhancement for a series of
Securities may cover one or more other series of Securities.
 
                                       50

     The descriptions of any insurance policies or bonds described in this

Prospectus or any Prospectus Supplement and the coverage thereunder do not
purport to be complete and are qualified in their entirety by reference to the
actual forms of such policies, copies of which are available upon request.
 
     Letter of Credit.  If any component of Credit Enhancement as to any series
of Securities is to be provided by a letter of credit (the 'Letter of Credit'),
a bank (the 'Letter of Credit Bank') will deliver to the Trustee an irrevocable
Letter of Credit. The Letter of Credit may provide direct coverage with respect
to the related Securities or, if specified in the related Prospectus Supplement,
support the Sponsor's or any other person's obligation pursuant to a Purchase
Obligation to make certain payments to the Trustee with respect to one or more
components of Credit Enhancement. The Letter of Credit Bank, as well as the
amount available under the Letter of Credit with respect to each component of
Credit Enhancement, will be specified in the applicable Prospectus Supplement.
The Letter of Credit will expire on the expiration date set forth in the related
Prospectus Supplement, unless earlier terminated or extended in accordance with
its terms. On or before each Payment Date, either the Letter of Credit Bank or
the Trustee (or other obligor under a Purchase Obligation) will be required to
make the payments specified in the related Prospectus Supplement after
notification from the Trustee, to be deposited in the related Distribution
Account, if and to the extent covered, under the applicable Letter of Credit.
 
     Mortgage Pool Insurance Policies.  Any mortgage pool insurance policy
('Mortgage Pool Insurance Policy') obtained by the Sponsor for each related
Trust Estate will be issued by the Pool Insurer named in the related Prospectus
Supplement. Each Mortgage Pool Insurance Policy will, subject to limitations
specified in the related Prospectus Supplement described below, cover Defaulted
Mortgage Losses in an amount equal to a percentage specified in the related
Prospectus Supplement (or in a Current Report on Form 8-K) of the aggregate
principal balance of the Mortgage Loans on the Cut-Off Date. As set forth under
'Maintenance of Credit Enhancement,' the Master Servicer will use reasonable
efforts to maintain the Mortgage Pool Insurance Policy and to present claims
thereunder to the Pool Insurer on behalf of itself, the Trustee and the
Securityholders. The Mortgage Pool Insurance Policies, however, are not blanket
policies against loss (typically, such policies do not cover Special Hazard
Losses, Fraud Losses and Bankruptcy Losses), since claims thereunder may only be
made respecting particular defaulted Mortgage Loans and only upon satisfaction
of certain conditions precedent described below due to a failure to pay
irrespective of the reason therefor.
 
     Special Hazard Insurance Policies.  Any insurance policy covering Special
Hazard Losses (a 'Special Hazard Insurance Policy') obtained by the Sponsor for
a Trust Estate will be issued by the insurer named in the related Prospectus
Supplement. Each Special Hazard Insurance Policy will, subject to limitations
described in the related Prospectus Supplement, protect holders of the related
series of Securities from (i) losses due to direct physical damage to a
Mortgaged Property other than any loss of a type covered by a hazard insurance
policy or a flood insurance policy, if applicable, and (ii) losses from partial
damage caused by reason of the application of the co-insurance clauses contained
in hazard insurance policies. See 'Hazard Insurance; Claims Thereunder.' A
Special Hazard Insurance Policy will not cover Extraordinary Losses. Aggregate
claims under a Special Hazard Insurance Policy will be limited to a maximum
amount of coverage, as set forth in the related Prospectus Supplement or in a
Current Report on Form 8-K. A Special Hazard Insurance Policy will provide that

no claim may be paid unless hazard and, if applicable, flood insurance on the
Mortgaged Property securing the Mortgage Loan has been kept in force and other
protection and preservation expenses have been paid by the Master Servicer.
 
     Subject to the foregoing limitations, in general a Special Hazard Insurance
Policy will provide that, where there has been damage to property securing a
foreclosed Mortgage Loan (title to which has been acquired by the insured) and
to the extent such damage is not covered by the hazard insurance policy or flood
insurance policy, if any, maintained by the Mortgagor or the Master Servicer or
the Sub-Servicer, the insurer will pay the lesser of (i) the cost of repair or
replacement of such property or (ii) up on transfer of the property to the
insurer, the unpaid principal balance of such Mortgage Loan at the time of
acquisition of such property by foreclosure or deed in lieu of foreclosure, plus
accrued interest at the Mortgage Rate to the date of claim settlement and
certain expenses incurred by the Master Servicer or the Sub-Servicer with
respect to such property. If the property is transferred to a third party in a
sale approved by the issuer of the Special Hazard Insurance Policy (the 'Special
Hazard Insurer'), the amount that the Special Hazard Insurer will pay will be
the amount under (ii) above reduced by the net proceeds of the sale of the
property.
 
                                       51

     As indicated under 'Description of the Securities--Assignment of Mortgage
Loans' above and to the extent set forth in the related Prospectus Supplement,
coverage in respect of Special Hazard Losses for a series of Securities may be
provided, in whole or in part by a type of special hazard instrument other than
a Special Hazard Insurance Policy or by means of the special hazard
representation of the Sponsor.
 
     Bankruptcy Bonds.  In the event of a personal bankruptcy of a Mortgagor, it
is possible that the bankruptcy court may establish the value of the Mortgaged
Property of such Mortgagor at an amount less than the then-outstanding,
principal balance of the Mortgage Loan secured by such Mortgaged Property (a
'Deficient Valuation'). The amount of the secured debt then could be reduced to
such value, and, thus, the holder of such Mortgage Loan would become an
unsecured creditor to the extent the outstanding principal balance of such
Mortgage Loan exceeds the value assigned to the Mortgaged Property by the
bankruptcy court. In addition, certain other modifications of the terms of a
Mortgage Loan can result from a bankruptcy proceeding, including a reduction in
the amount of the monthly payment on the related Mortgage Loan or a reduction in
the mortgage interest rate (a 'Debt Service Reduction'; Debt Service Reductions
and Deficient Valuations, collectively referred to herein as 'Bankruptcy
Losses'). See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Anti-Deficiency Legislation and Other Limitations on Lenders.' Any
bankruptcy bond ('Bankruptcy Bond') to provide coverage for Bankruptcy Losses
for proceedings under the federal Bankruptcy Code obtained by the Sponsor for a
Trust Estate will be issued by an insurer named in the related Prospectus
Supplement. The level of coverage under each Bankruptcy Bond will be set forth
in the applicable Prospectus Supplement or in a Current Report on Form 8-K.
 
     Reserve Funds.  If so provided in the related Prospectus Supplement, the
Sponsor will deposit or cause to be deposited in an account (a 'Reserve Fund')
any combination of cash, one or more irrevocable letters of credit or one or

more Eligible Investments in specified amounts, amounts otherwise distributable
to Subordinate Securityholders or the owners of any Originator's Retained Yield,
or any other instrument satisfactory to the Rating Agency or Agencies, which
will be applied and maintained in the manner and under the conditions specified
in such Prospectus Supplement. In the alternate or in addition to such deposit
to the extent described in the related Prospectus Supplement, a Reserve Fund may
be funded through application of all or a portion of amounts otherwise payable
on any related Subordinate Securities from the Originator's Retained Yield or
otherwise. In addition, with respect to any series of Securities as to which
Credit Enhancement includes a Letter of Credit, if so specified in the related
Prospectus Supplement, under certain circumstances the remaining amount of the
Letter of Credit may be drawn by the Trustee and deposited in a Reserve Fund.
Amounts in a Reserve Fund may be distributed to Securityholders, or applied to
reimburse the Master Servicer for outstanding advances or may be used for other
purposes, in the manner and to the extent specified in the related Prospectus
Supplement. A Trust Estate may contain more than one Reserve Fund, each of which
may apply only to a specified class of Securities or to specified Mortgage
Assets.
 
     Financial Guaranty Insurance Policies.  If so specified in the related
Prospectus Supplement, a financial guaranty insurance policy or surety bond
('Financial Guaranty Insurance Policy') may be obtained and maintained for each
class or series of Securities. The issuer of any Financial Guaranty Insurance
Policy (a 'Financial Guaranty Insurer') will be described in the related
Prospectus Supplement. A copy of any such Financial Guaranty Insurance Policy
will be attached as an exhibit to the related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, a
Financial Guaranty Insurance Policy will unconditionally and irrevocably
guarantee to Securityholders that an amount equal to each full and complete
insured payment will be received by an agent of the Trustee (an 'Insurance
Paying Agent') on behalf of Securityholders, for distribution by the Trustee to
each Securityholder. The 'insured payment' will be defined in the related
Prospectus Supplement, and will generally equal the full amount of the
distributions of principal and interest to which Securityholders are entitled
under the related Pooling and Servicing Agreement plus any other amounts
specified therein or in the related Prospectus Supplement (the 'Insured
Payment').
 
     Financial Guaranty Insurance Policies may apply only to certain specified
classes, or may apply at the Mortgage Asset level and only to specified Mortgage
Assets.
 
     The specific terms of any Financial Guaranty Insurance Policy will be as
set forth in the related Prospectus Supplement. Financial Guaranty Insurance
Policies may have limitations including (but not limited to) limitations on the
insurer's obligation to guarantee the obligations of the Originators to
repurchase or substitute for any
 
                                       52

Mortgage Loans, Financial Guaranty Insurance Policies will not guarantee any
specified rate of prepayments and/or to provide funds to redeem Securities on
any specified date.

 
     Subject to the terms of the related Pooling and Servicing Agreement, the
Financial Guaranty Insurer may be subrogated to the rights of each
Securityholder to receive payments under the Securities to the extent of any
payment by such Financial Guaranty Insurer under the related Financial Guaranty
Insurance Policy.
 
     Other Insurance, Guarantees and Similar Instruments or Agreements.  If
specified in the related Prospectus Supplement, a Trust may include in lieu of
some or all of the foregoing or in addition thereto third party guarantees, and
other arrangements for maintaining timely payments or providing additional
protection against losses on all or any specified portion of the assets included
in such Trust, paying administrative expenses, or accomplishing such other
purpose as may be described in the Prospectus Supplement. The Trust may include
a guaranteed investment contract or reinvestment agreement pursuant to which
funds held in one or more accounts will be invested at a specified rate. If any
class of Securities has a floating interest rate, or if any of the Mortgage
Assets has a floating interest rate, the Trust may include an interest rate swap
contract, an interest rate cap agreement or similar contract providing limited
protection against interest rate risks.
 
     Cross Support.  If specified in the Prospectus Supplement, the beneficial
ownership of separate groups of assets included in a Trust may be evidenced by
separate classes of the related series of Securities. In such case, credit
support may be provided by a cross-support feature which requires that
distributions be made with respect to one class of Securities may be made from
excess amounts available from other asset groups within the same Trust which
support other classes of Securities. The Prospectus Supplement for a series that
includes a cross-support feature will describe the manner and conditions for
applying such cross-support feature.
 
     If specified in the Prospectus Supplement, the coverage provided by one or
more forms of credit support may apply concurrently to two or more separate
Trusts. If applicable, the Prospectus Supplement will identify the Trusts to
which such credit support relates and the manner of determining the amount of
the coverage provided thereby and of the application of such coverage to the
identified Trusts.
 
     Overcollateralization.  If specified in the Prospectus Supplement,
subordination provisions of a Trust may be used to accelerate to a limited
extent the amortization of one or more classes of Securities relative to the
amortization of the related Mortgage Loans. The accelerated amortization is
achieved by the application of certain excess interest to the payment of
principal of one or more classes of Securities. This acceleration feature
creates, with respect to the Mortgage Loans or groups thereof, over
collateralization which results from the excess of the aggregate principal
balance of the related Mortgage Loans, or a group thereof, over the principal
balance of the related class of Securities. Such acceleration may continue for
the life of the related Security, or may be limited. In the case of limited
acceleration, once the required level of overcollateralization is reached, and
subject to certain provisions specified in the related Prospectus Supplement,
such limited acceleration feature may cease, unless necessary to maintain the
required level of overcollateralization.
 

     Maintenance of Credit Enhancement.  To the extent that the applicable
Prospectus Supplement does not expressly provide for Credit Enhancement
arrangements in lieu of some or all of the arrangements mentioned below, the
following paragraphs shall apply.
 
     If a form of Credit Enhancement has been obtained for a series of
Securities, the Sponsor will be obligated to exercise its best reasonable
efforts to keep or cause to be kept such form of credit support in full force
and effect throughout the term of the applicable Pooling and Servicing
Agreement, unless coverage thereunder has been exhausted through payment of
claims or otherwise, or substitution therefor is made as described below under
'Reduction or Substitution of Credit Enhancement.'
 
     In lieu of the Sponsor's obligation to maintain a particular form of Credit
Enhancement, the Sponsor may obtain a substitute or alternate form of Credit
Enhancement. If the Master Servicer obtains such a substitute form of Credit
Enhancement, it will maintain and keep such form of Credit Enhancement in full
force and effect as provided herein. Prior to its obtaining any substitute or
alternate form of Credit Enhancement, the Sponsor will obtain written
confirmation from the Rating Agency or Agencies that rated the related series of
Securities that the substitution or alternate form of Credit Enhancement for the
existing Credit Enhancement will not adversely affect the then-current ratings
assigned to such Securities by such Rating Agency or Agencies.
 
                                       53

     The Master Servicer, on behalf of itself, the Trustee and Securityholders,
will provide the Trustee information required for the Trustee to draw under a
Letter of Credit or Financial Guaranty Insurance Policy, will present claims to
each Pool Insurer, to the issuer of each Special Hazard Insurance Policy or
other special hazard instrument, to the issuer of each Bankruptcy Bond and will
take such reasonable steps as are necessary to permit recovery under such Letter
of Credit, Financial Guaranty Insurance Policy, Purchase Obligation, insurance
policies or comparable coverage respecting defaulted Mortgage Loans or Mortgage
Loans which are the subject of a bankruptcy proceeding. Additionally, the Master
Servicer will present such claims and take such steps as are reasonably
necessary to provide for the performance by another party of its Purchase
Obligation. As set forth above, all collections by the Master Servicer under any
Purchase Obligation, any Mortgage Pool Insurance Policy, or any Bankruptcy Bond
and, where the related property has not been restored, any Special Hazard
Insurance Policy, are to be deposited initially in the Principal and Interest
Account and ultimately in the Distribution Account, subject to withdrawal as
described above. All draws under any Letter of Credit or Financial Guaranty
Insurance Policy will be deposited directly in the Distribution Account.
 
     If any property securing a defaulted Mortgage Loan is damaged and proceeds,
if any, from the related hazard insurance policy or any applicable Special
Hazard Instrument are insufficient to restore the damaged property to a
condition sufficient to permit recovery under any applicable form of Credit
Enhancement, the Master Servicer is not required to expend its own funds to
restore the damaged property unless it determines (i) that such restoration will
increase the proceeds to one or more classes of Securityholders on liquidation
of the Mortgage Loan after reimbursement of the Master Servicer for its expenses
and (ii) that such expenses will be recoverable by it through Liquidation

Proceeds or Insurance Proceeds. If recovery under any applicable form of Credit
Enhancement is not available because the Master Servicer has been unable to make
the above determinations, has made such determinations incorrectly or recovery
is not available for any other reason, the Master Servicer is nevertheless
obligated to follow such normal practices and procedures (subject to the
preceding sentence) as it deems necessary or advisable to realize upon the
defaulted Mortgage Loan and in the event such determination has been incorrectly
made, is entitled to reimbursement of its expenses in connection with such
restoration.
 
     Reduction or Substitution of Credit Enhancement.  Unless otherwise
specified in the related Prospectus Supplement, the amount of credit support
provided pursuant to any of the Credit Enhancements (including, without
limitation, a Mortgage Pool Insurance Policy, Financial Guaranty Insurance
Policy, Special Hazard Insurance Policy, Bankruptcy Bond, Letter of Credit, or
any alternative form of Credit Enhancement) may be reduced under certain
specified circumstances. In addition, if so described in the related Prospectus
Supplement, any formula used in calculating the amount or degree of Credit
Enhancement may be changed without the consent of the Securityholders upon
written confirmation from each Rating Agency then rating the Securities that
such change will not adversely affect the then-current rating or ratings
assigned to the Securities. In most cases, the amount available pursuant to any
Credit Enhancement will be subject to periodic reduction in accordance with a
schedule or formula on a nondiscretionary basis pursuant to the terms of the
related Pooling and Servicing Agreement as the aggregate outstanding principal
balance of the Mortgage Loans declines. Additionally, in certain cases, such
credit support (and any replacements therefor) may be replaced, reduced or
terminated upon the written assurance from each applicable Rating Agency that
the then-current rating of the related series of Securities will not be
adversely affected. Furthermore, in the event that the credit rating of any
obligor under any applicable Credit Enhancement is downgraded, the credit rating
of the related Securities may be downgraded to a corresponding level, and,
unless otherwise specified in the related Prospectus Supplement, the Sponsor
thereafter will not be obligated to obtain replacement credit support in order
to restore the rating of the Securities, and also will be permitted to replace
such credit support with other Credit Enhancement instruments issued by obligors
whose credit ratings are equivalent to such downgraded level and in lower
amounts which would satisfy such downgraded level, provided that the
then-current, albeit downgraded, rating of the related series of Securities is
maintained. Where the credit support is in the form of a Reserve Fund, a
permitted reduction in the amount of Credit Enhancement will result in a release
of all or a portion of the assets in the Reserve Fund to the Sponsor, the Master
Servicer, one or more Originators or such other person that is entitled thereto.
Any assets so released will not be available to fund distribution obligations in
future periods.
 
                                       54

                      HAZARD INSURANCE; CLAIMS THEREUNDER
 
     Each Mortgage Loan will be required to be covered by a hazard insurance
policy (as described below). The following is only a brief description of
certain insurance policies and does not purport to summarize or describe all of
the provisions of these policies. Such insurance is subject to underwriting and

approval of individual Mortgage Loans by the respective insurers. The
descriptions of any insurance policies described in this Prospectus or any
Prospectus Supplement and the coverage thereunder do not purport to be complete
and are qualified in their entirety by reference to such forms of policies,
sample copies of which are available from the Trustee upon request.
 
HAZARD INSURANCE POLICIES
 
     The terms of the Mortgage Loans require each Mortgagor to maintain a hazard
insurance policy for the Mortgage Loan. Additionally, the Pooling and Servicing
Agreement will require the Master Servicer to cause to be maintained with
respect to each Mortgage Loan a hazard insurance policy with a generally
acceptable carrier that provides for fire and extended coverage relating to such
Mortgage Loan in an amount not less than the least of (i) the outstanding
principal balance of the Mortgage Loan, (ii) the minimum amount required to
compensate for damage or loss on a replacement cost basis or (iii) the full
insurable value of the premises.
 
     If a Mortgage Loan at the time of origination relates to a Mortgaged
Property in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards, the Master Servicer will be
required to maintain with respect thereto a flood insurance policy in a form
meeting the requirements of the then-current guidelines of the Federal Insurance
Administration with a generally acceptable carrier in an amount representing
coverage, and which provides for recovery by the Master Servicer on behalf of
the Trust of insurance proceeds relating to such Mortgage Loan of not less than
the least of (i) the outstanding principal balance of the Mortgage Loan, (ii)
the minimum amount required to compensate for damage or loss on a replacement
cost basis, (iii) the maximum amount of insurance that is available under the
Flood Disaster Protection Act of 1973. Pursuant to the related Pooling and
Servicing Agreement, the Master Servicer will be required to indemnify the Trust
out of the Master Servicer's own funds for any loss to the Trust resulting from
the Master Servicer's failure to maintain such flood insurance.
 
     In the event that the Master Servicer obtains and maintains a blanket
policy insuring against fire with extended coverage and against flood hazards on
all of the Mortgage Loans, then, to the extent such policy names the Master
Servicer as loss payee and provides coverage in an amount equal to the aggregate
unpaid principal balance on the Mortgage Loans without co-insurance, and
otherwise complies with the requirements of the Pooling and Servicing Agreement,
the Master Servicer shall be deemed conclusively to have satisfied its
obligations with respect to fire and hazard insurance coverage under the Pooling
and Servicing Agreement. Such blanket policy may contain a deductible clause, in
which case the Master Servicer will be required, in the event that there shall
not have been maintained on the related Mortgaged Property a policy complying
with the Pooling and Servicing Agreement, and there shall have been a loss that
would have been covered by such policy, to deposit in the Principal and Interest
Account from the Master Servicer's own funds the difference, if any, between the
amount that would have been payable under a policy complying with the Pooling
and Servicing Agreement and the amount paid under such blanket policy.

facilitate certain issuances of Securities. The use of the Transferor will not
affect the obligations of the Sponsor with respect to the related Trust or the
related Securities. If the Transferor is to be involved in a particular offering
the related Prospectus Supplement will describe its role in such offering; for
purposes of this Prospectus the role of the Transferor is subsumed in the role

     Unless otherwise specified in the related Prospectus Supplement, ADVANTA
Mortgage Corp. USA will act as the Master Servicer for a series of Securities.
 
     ADVANTA Mortgage Corp. USA was acquired by ADVANTA Corp., a Delaware

                      THE POOLING AND SERVICING AGREEMENT
 
     As described above under 'Description of the Securities--General,' each
series of Securities will be issued pursuant to a Pooling and Servicing
Agreement as described in that section. The following summaries describe certain
additional provisions common to each Pooling and Servicing Agreement.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES; ORIGINATOR'S RETAINED
YIELD
 

     Each servicer, whether the Master Servicer or any Sub-Servicer (either the
Master Servicer or any Sub-Servicer being a 'Servicer'), will retain a fee in
connection with its servicing activities for each series of Securities equal to
the percentage per annum specified in the related Prospectus Supplement or
Current Report on Form 8-K (the 'Base Servicing Fee'), generally payable monthly
with respect to each Mortgage Loan directly serviced by such Servicer at
one-twelfth the annual rate, of the then-outstanding principal amount of each
such Mortgage Loan as of the first day of each calendar month. The Master
Servicer acting as master servicer with respect to Mortgage Loans being serviced
directly by a Sub-Servicer will retain a fee equal to the percentage per annum
specified in the related Prospectus Supplement or Current Report on Form 8-K
('Master Servicing Fee'), generally payable monthly on one-twelfth the annual
rate, of the then-outstanding principal amount of each such Mortgage Loan as of
the first day of each calendar month. The Base Servicing Fees and the Master
Servicing Fee are collectively referred to as the 'Servicing Fee.'
 
     In addition to the Base Servicing Fee, each Servicer will generally be
entitled under the Pooling and Servicing Agreement to retain additional
servicing compensation in the form of prepayment charges, release fees, bad
check charges, assumption fees, late payment charges, or any other
servicing-related fees, Net Liquidation Proceeds not required to be deposited in
the Principal and Interest Account pursuant to the Pooling and Servicing
Agreement, and similar items.
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer will pay or cause to be paid certain ongoing expenses associated with
each Trust Estate and incurred by it in connection with its responsibilities
under the Pooling and Servicing Agreement, including, without limitation,
payment of any fee or other amount payable in respect of any alternative Credit
Enhancement arrangements, payment of the fees and disbursements of the Trustee
or accountant, any custodian appointed by the Trustee, the Security Registrar
and any Paying Agent, and payment of expenses incurred in enforcing the
obligations of Sub-Servicers and Originators. The Master Servicer may be
entitled to reimbursement of expenses incurred in enforcing the
 
                                       56

obligations of Sub-Servicers and Originators under certain limited
circumstances. In addition, as indicated in the preceding section, the Master
Servicer will be entitled to reimbursements for certain expenses incurred by it
in connection with Liquidated Mortgage Loans and in connection with the
restoration of Mortgaged Properties, such right of reimbursement being prior to
the rights of Securityholders to receive any related Liquidation Proceeds
(including Insurance Proceeds).
 
     The Prospectus Supplement for a series of Securities will specify if there
will be any Originator's Retained Yield retained. Any such Originator's Retained
Yield will be a specified portion of the interest payable on each Mortgage Loan
in a Mortgage Pool. Any such Originator's Retained Yield will be established on
a loan-by-loan basis and the amount thereof with respect to each Mortgage Loan
in a Mortgage Pool will be specified on an exhibit to the related Pooling and
Servicing Agreement. Any Originator's Retained Yield in respect of a Mortgage
Loan will represent a specified portion of the interest payable thereon and will
not be part of the related Trust Estate. Any partial recovery of interest in

respect of a Mortgage Loan will be allocated between the owners of any
Originator's Retained Yield and the holders of classes of Securities entitled to
payments of interest as provided in the Prospectus Supplement and the applicable
Pooling and Servicing Agreement.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Pooling and Servicing Agreement will require the Master Servicer to
deliver annually to the Trustee and any Credit Enhancer, an officers'
certificate stating, as to each signer thereof, that (i) a review of the
activities of the Master Servicer during such preceding year and of performance
under the related Pooling and Servicing Agreement has been made under such
officers' supervision, and (ii) to the best of such officers' knowledge, based
on such review, the Master Servicer has fulfilled all its obligations under the
related Pooling and Servicing Agreement for such year, or, if there has been a
default in the fulfillment of any such obligations, specifying each such default
known to such officers and the nature and status thereof including the steps
being taken by the Master Servicer to remedy such defaults.
 
     Each Pooling and Servicing Agreement will require the Master Servicer to
cause to be delivered to the Trustee and any Credit Enhancer a letter or letters
of a firm of independent, nationally recognized certified public accountants
reasonably acceptable to the Credit Enhancer, if applicable, stating that such
firm has, with respect to the Master Servicer's overall servicing operations (i)
performed applicable tests in accordance with the compliance testing procedures
as set forth in Appendix 3 of the Audit Guide for Audits of HUD Approved
Nonsupervised Mortgagees or (ii) examined such operations in accordance with the
requirements of the Uniform Single Audit Program for Mortgage Bankers, and in
either case stating such firm's conclusions relating thereto.
 
     Copies of the annual accountants' statement and the annual statement of
officers of the Master Servicer may be obtained by Securityholders without
charge upon written request to the Master Servicer.
 
REMOVAL AND RESIGNATION OF THE MASTER SERVICER
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement will provide that the Master Servicer may not
resign from its obligations and duties thereunder, except in connection with a
permitted transfer of servicing, unless such duties and obligations are no
longer permissible under applicable law or are in material conflict by reason of
applicable law with any other activities of a type and nature presently carried
on by it. No such resignation will become effective until the Trustee has
assumed the Master Servicer's obligations and duties under the Pooling and
Servicing Agreement. The Trustee, the Securityholders or a Credit Enhancer, if
applicable, will have the right, pursuant to the related Pooling and Servicing
Agreement, to remove the Master Servicer upon the occurrence of any of (a)
certain events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceedings regarding the Master Servicer and certain
actions by the Master Servicer indicating its insolvency or inability to pay its
obligations; (b) the failure of the Master Servicer to perform any one or more
of its material obligations under the Pooling and Servicing Agreement as to
which the Master Servicer shall continue in default with respect thereto for a
specified period, generally of sixty (60) days, after notice by the Trustee or

any Credit Enhancer (if required by the Pooling and Servicing Agreement) of said
failure; or (c) the failure of the Master Servicer to cure any breach of any of
its representations and warranties set forth in the Pooling and Servicing
Agreement which materially and adversely
 
                                       57

affects the interests of the Securityholders or any Credit Enhancer, for a
specified period, generally of thirty (30) days after the Master Servicer's
discovery or receipt of notice thereof.
 
     The Pooling and Servicing Agreement may also provide that the related
Credit Enhancer may remove the Master Servicer upon the occurrence of any of
certain events including:
 
          (i) with respect to any Payment Date, if the total available funds
     with respect to the Mortgage Loans Group will be less than the related
     distribution amount on the class of credit-enhanced securities in respect
     of such Payment Date; provided, however, that the Credit Enhancer generally
     will have no right to remove the Master Servicer pursuant to the provision
     described in this clause (i) if the Master Servicer can demonstrate to the
     reasonable satisfaction of the Credit Enhancer that such event was due to
     circumstances beyond the control of the Master Servicer;
 
          (ii) the failure by the Master Servicer to make any required Servicing
     Advance;
 
          (iii) the failure of the Master Servicer to perform one or more of its
     material obligations under the Pooling and Servicing Agreement; or
 
          (iv) the failure by the Master Servicer to make any required
     Delinquency Advance or to pay any Compensating Interest;
 
provided, however, that prior to any removal of the Master Servicer by the
related Credit Enhancer pursuant to clauses (i), (ii) or (iii) above the Master
Servicer shall first have been given by the related Credit Enhancer notice of
the occurrence of one or more of the events set forth in clauses (i) or (ii)
above and the Master Servicer shall not have remedied, or shall not have taken
action satisfactory to such Credit Enhancer to remedy, such event or events
within a specified period, generally 30 days (60 days with respect to clause
(iii)) after the Master Servicer's receipt of such notice; and provided, further
that in the event of the refusal or inability of the Master Servicer to make any
required Delinquency Advance or to pay any Compensating Interest as described in
clause (iv) above, such removal shall be effective (without the requirement of
any action on the part of such Credit Enhancer or of the Trustee) not later than
a shorter specified period, generally not in excess of five business days,
following the day on which the Trustee notifies an authorized officer of the
Master Servicer that a required Delinquency Advance or to pay any Compensating
Interest has not been received by the Trustee.
 
AMENDMENTS
 
     The Trustee, the Sponsor and the Master Servicer may at any time and from
time to time, with the prior approval of the related Credit Enhancer, if

required, but without the giving of notice to or the receipt of the consent of
the Securityholders, amend a Pooling and Servicing Agreement, and the Trustee
will be required to consent to such amendment, for the purposes of (x) (i)
curing any ambiguity, or correcting or supplementing any provision of such
Pooling and Servicing Agreement which may be inconsistent with any other
provision of the Pooling and Servicing Agreement, (ii) in connection with a
Trust making REMIC elections, if accompanied by an approving opinion of counsel
experienced in federal income tax matters, removing the restriction against the
transfer of a REMIC residual security to a Disqualified Organization (as such
term is defined in the Code) or (iii) complying with the requirements of the
Code and the regulations proposed or promulgated thereunder; provided, however,
that such action shall not, as evidenced by an opinion of counsel delivered to
the Trustee, materially and adversely affect the interests of any Securityholder
(without its written consent) or (y) such other purposes set forth in the
related Pooling and Servicing Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement may also be amended by the Trustee, the Sponsor
and the Master Servicer at any time and from time to time, with the prior
written approval of the related Credit Enhancer, if required, and not less than
a majority of the Percentage Interest represented by each related class of
Securities then outstanding, for the purpose of adding any provisions or
changing in any manner or eliminating any of the provisions of such Pooling and
Servicing Agreement or of modifying in any manner the rights of the
Securityholders thereunder; provided, however, that no such amendment shall (a)
change in any manner the amount of, or delay the timing of, payments which are
required to be distributed to any Securityholders without the consent of the
holder of such Security or (b) change the aforesaid percentages of Percentage
Interest which are required to consent to any such amendments, without the
consent of the holders of all Securities of the class or classes affected then
outstanding.
 
                                       58

TERMINATION; RETIREMENT OF SECURITIES
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement will provide that a Trust will terminate upon
the earlier of (i) the payment to the Securityholders of all Securities issued
by the Trust from amounts other than those available under, if applicable, the
related Credit Enhancement of all amounts required to be paid to such
Securityholders upon the later to occur of (a) the final payment or other
liquidation (or any advance made with respect thereto) of the last Mortgage Loan
in the Trust Estate or (b) the disposition of all property acquired in respect
of any Mortgage Loan remaining in the Trust Estate, (ii) any time when a
Qualified Liquidation (as defined in the Code) of the Trust Estate (if the
related Trust is a REMIC) is effected. In no event, however, will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the survivor of certain persons named in such Pooling
and Servicing Agreement. Written notice of termination of the Pooling and
Servicing Agreement will be given to each Securityholder, and the final
distribution will be made only upon surrender and cancellation of the Securities
at an office or agency appointed by the Trustee that will be specified in the
notice of termination. If the Securityholders are permitted to terminate the

trust under the applicable Pooling and Servicing Agreement, a penalty may be
imposed upon the Securityholders based upon the fee that would be foregone by
the Master Servicer because of such termination.
 
     Any purchase of Mortgage Loans and property acquired in respect of Mortgage
Loans evidenced by a series of Securities shall be made at the option of the
Master Servicer, the Sponsor or, if applicable, the holder of the REMIC Residual
Securities at the price specified in the related Prospectus Supplement. The
exercise of such right will effect earlier than expected retirement of the
Securities of that series, but the right of the Master Servicer, the Sponsor or,
if applicable, such holder to so purchase is, unless otherwise specified in the
applicable Prospectus Supplement, subject to the aggregate principal balance of
the Mortgage Loans for that series as of any Remittance Date being less than the
percentage specified in the related Prospectus Supplement of the aggregate
principal balance of the Mortgage Loans at the Cut-Off Date for that series. The
Prospectus Supplement for each series of Securities will set forth the amounts
that the holders of such Securities will be entitled to receive upon such
earlier than expected retirement. If a REMIC election has been made, the
termination of the related Trust Estate will be effected in a manner consistent
with applicable federal income tax regulations and its status as a REMIC.
 
THE TRUSTEE
 
     The Trustee under each Pooling and Servicing Agreement will be named in the
related Prospectus Supplement. Each Pooling and Servicing Agreement will provide
that the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by the Pooling and Servicing Agreement at the request or
direction of any of the Securityholders, unless such Securityholders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction.
 
     The Trustee may execute any of the trusts or powers granted by each Pooling
and Servicing Agreement or perform any duties thereunder either directly or by
or through agents or attorneys, and the Trustee will not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed and
supervised with due care by it thereunder.
 
     Pursuant to each Pooling and Servicing Agreement, the Trustee will not be
liable for any action it takes or omits to take in good faith which it
reasonably believes to be authorized by an authorized officer of any person or
within its rights or powers under the Pooling and Servicing Agreement.
 
     Unless otherwise described in the related Prospectus Supplement, each
Pooling and Servicing Agreement will permit the removal of the Trustee upon the
occurrence and continuance of one of the following events:
 
          (1) the Trustee shall fail to distribute to the Securityholders
     entitled thereto on any Payment Date amounts available for distribution in
     accordance with the terms of the Pooling and Servicing Agreement; or
 
          (2) the Trustee shall default in the performance of, or breach, any
     covenant or agreement of the Trustee in the Pooling and Servicing
     Agreement, or if any representation or warranty of the Trustee made in the

     Pooling and Servicing Agreement or in any certificate or other writing
     delivered pursuant thereto or in
 
                                       59

     connection therewith shall prove to be incorrect in any material respect as
     of the time when the same shall have been made, and such default or breach
     shall continue or not be cured for the period then specified in the related
     Pooling and Servicing Agreement after the Trustee shall have received
     notice specifying such default or breach and requiring it to be remedied;
     or
 
          (3) a decree or order of a court or agency or supervisory authority
     having jurisdiction for the appointment of a conservator or receiver or
     liquidator in any insolvency, readjustment of debt, marshalling of assets
     and liabilities or similar proceedings, or for the winding-up or
     liquidation of its affairs, shall have been entered against the Trustee,
     and such decree or order shall have remained in force undischarged or
     unstayed for the period then specified in the related Pooling and Servicing
     Agreement; or
 
          (4) a conservator or receiver or liquidator or sequestrator or
     custodian of the property of the Trustee is appointed in any insolvency,
     readjustment of debt, marshalling of assets and liabilities or similar
     proceedings of or relating to the Trustee or relating to all or
     substantially all of its property; or
 
          (5) the Trustee shall become insolvent (however insolvency is
     evidenced), generally fail to pay its debts as they come due, file or
     consent to the filing of a petition to take advantage of any applicable
     insolvency or reorganization statute, make an assignment for the benefit of
     its creditors, voluntarily suspend payment of its obligations, or take
     corporate action for the purpose of any of the foregoing.
 
     If an event described above occurs and is continuing, then, and in every
such case (i) the Sponsor, (ii) the Securityholders (on the terms set forth in
the related Pooling and Servicing Agreement), or (iii) if there is a Credit
Enhancer, such Credit Enhancer may, whether or not the Trustee has resigned,
immediately, concurrently with the giving of notice to the Trustee, and without
delay, appoint a successor Trustee pursuant to the terms of the Pooling and
Servicing Agreement.
 
     No Securityholder will have any right to institute any proceeding, judicial
or otherwise, with respect to a Pooling and Servicing Agreement or any Credit
Enhancement, if applicable, or for the appointment of a receiver or trustee, or
for any other remedy under the Pooling and Servicing Agreement, unless:
 
          (1) such Securityholder has previously given written notice to the
     Sponsor and the Trustee of such Securityholder's intention to institute
     such proceeding;
 
          (2) the Securityholders of not less than 25% of the Percentage
     Interests represented by certain specified classes of Securities then
     outstanding shall have made written request to the Trustee to institute

     such proceeding;
 
          (3) such Securityholder or Securityholders have offered to the Trustee
     reasonable indemnity, against the costs, expenses and liabilities to be
     incurred in compliance with such request;
 
          (4) the Trustee for the period specified in the related Pooling and
     Servicing Agreement, generally not in excess of 60 days after receipt of
     such notice, request and offer of indemnity, has failed to institute such
     proceeding;
 
          (5) as long as such action affects any credit-enhanced class of
     Securities outstanding, the related Credit Enhancer has consented in
     writing thereto; and
 
          (6) no direction inconsistent with such written request has been given
     to the Trustee during such specified period by the Securityholders of a
     majority of the Percentage Interests represented by certain specified
     classes of Securities.
 
     No one or more Securityholders will have any right in any manner whatever
by virtue of, or by availing themselves of, any provision of the Pooling and
Servicing Agreement to affect, disturb or prejudice the rights of any other
Securityholder of the same class or to obtain or to seek to obtain priority or
preference over any other Securityholder of the same class or to enforce any
right under the Pooling and Servicing Agreement, except in the manner provided
in the Pooling and Servicing Agreement and for the equal and ratable benefit of
all of the Securityholders of the same class.
 
     In the event the Trustee receives conflicting or inconsistent requests and
indemnity from two or more groups of Securityholders, each representing less
than a majority of the applicable class of Securities, the Trustee in its
 
                                       60

sole discretion may determine what action, if any, shall be taken,
notwithstanding any other provision of the Pooling and Servicing Agreement.
 
     Notwithstanding any other provision in the Pooling and Servicing Agreement,
the Securityholder of any Security has the right, which is absolute and
unconditional, to receive distributions to the extent provided in the Pooling
and Servicing Agreement with respect to such Security or to institute suit for
the enforcement of any such distribution, and such right shall not be impaired
without the consent of such Security.
 
     Either (i) the Securityholders of a majority of the Percentage Interests
represented by certain specified classes of Securities then outstanding or (ii)
if there is a Credit Enhancer, such Credit Enhancer may direct the time, method
and place of conducting any proceeding for any remedy available to the Sponsor
with respect to the Certificates or exercising any trust or power conferred on
the Trustee with respect to such Certificates; provided that:
 
          (1) such direction shall not be in conflict with any rule of law or
     with a Pooling and Servicing Agreement;

 
          (2) the Sponsor or the Trustee, as the case may be, shall have been
     provided with indemnity satisfactory to them; and
 
          (3) the Sponsor or the Trustee, as the case may be, may take any other
     action deemed proper by the Trustee which is not inconsistent with such
     direction; provided, however, that the Sponsor or the Trustee, as the case
     may be, need not take any action which they determine might involve them in
     liability or may be unjustly prejudicial to the Securityholders not so
     directing.
 
     The Trustee will be liable under the Pooling and Servicing Agreement only
to the extent of the obligations specifically imposed upon and undertaken by the
Trustee therein. Neither the Trustee nor any of the directors, officers,
employees or agents of the Trustee will be under any liability on any Security
or otherwise to any Account, the Sponsor, the Master Servicer or any
Securityholder for any action taken or for refraining from the taking of any
action in good faith under a Pooling and Servicing Agreement, or for errors in
judgment; provided, however, that such provision shall not protect the Trustee
or any such person against any liability which would otherwise be imposed by
reason of negligent action, negligent failure to act or willful misconduct in
the performance of duties or by reason of reckless disregard of obligations and
duties thereunder.
 
                                       61




                              YIELD CONSIDERATIONS
 
     The yield to maturity of a Security will depend on the price paid by the
holder for such Security, the Pass-Through Rate on any such Security entitled to
payments of interest (which Pass-Through Rate may vary if so specified in the
related Prospectus Supplement) and the rate of payment of principal on such
Security (or the rate at which the notional amount thereof is reduced if such
Security is not entitled to payments of principal) and other factors.
 
     Each month the interest payable on an actuarial type of Mortgage Loan will
be calculated as one-twelfth of the applicable Mortgage Rate multiplied by the
principal balance of such Mortgage Loan outstanding as of a specified day,
usually the first day of the month prior to the month in which the Payment Date
for the related series of Securities occurs, after giving effect to the payment
of principal due on such day, subject to any Deferred Interest. With respect to
date of payment Mortgage Loans, interest is charged to the Mortgagor at the
Mortgage Rate on the outstanding principal balance of such Note and calculated
based on the number of days elapsed between receipt of the Mortgagor's last
payment through receipt of the Mortgagor's most current payments. The amount of
such payments with respect to each Mortgage Loan distributed (or accrued in the
case of Deferred Interest or Accrual Securities) either monthly, quarterly or
semi-annually to holders of a class of Securities entitled to payments of
interest will be similarly calculated on the basis of such class' specified
percentage of each such payment of interest (or accrual in the case of Accrual
Securities) and will be expressed as a fixed, adjustable or variable
Pass-Through Rate payable on the outstanding principal balance or notional
amount of such Security, calculated as described herein and in the related
Prospectus Supplement. Holders of Strip Securities or a class of Securities
having a fixed Pass-Through Rate that varies based on the weighted average
Mortgage Rate of the underlying Mortgage Loans will be affected by
disproportionate prepayments and repurchases of Mortgage Loans having higher Net
Mortgage Rates or rates applicable to the Strip Securities, as applicable.
 
     The effective yield to maturity to each holder of fixed-rate Securities
entitled to payments of interest will be below that otherwise produced by the
applicable Pass-Through Rate and purchase price of such Security because, while
interest will accrue on each Mortgage Loan from the first day of each month, the
distribution of such interest will be made on the 25th day (or, if such day is
not a business day, the next succeeding business day) of the month (or, in the
case of quarterly-pay Securities, the twenty-fifth day of every third month, or,
in the case of semi-annual-pay Securities, the twenty-fifth day of every sixth
month) following the month of accrual.
 
     A class of Securities may be entitled to payments of interest at a fixed
Pass-Through Rate specified in the related Prospectus Supplement, a variable
Pass-Through Rate or adjustable Pass-Through Rate calculated based on the
weighted average of the Mortgage Rates (net of Servicing Fees and any
Originator's Retained Yield (each, a 'Net Mortgage Rate')) of the related
Mortgage Loans for the designated periods preceding the Payment Date if so
specified in the related Prospectus Supplement, or at such other variable rate
as may be specified in the related Prospectus Supplement.
 

     As will be described in the related Prospectus Supplement, the aggregate
payments of interest on a class of Securities, and the yield to maturity
thereon, will be effected by the rate of payment of principal on the Securities
(or the rate of reduction in the notional balance of Securities entitled only to
payments of interest) and, in the case of Securities evidencing interests in ARM
Loans, by changes in the Net Mortgage Rates on the ARM Loans. See 'Maturity and
Prepayment Considerations' below. The yield on the Securities also will be
effected by liquidations of Mortgage Loans following Mortgagor defaults and by
purchases of Mortgage Loans required by the Pooling and Servicing Agreement in
the event of breaches of representations made in respect of such Mortgage Loans
by the Sponsor, the Originators, the Master Servicer and others, or repurchases
due to conversions of ARM Loans to a fixed interest rate. See 'Mortgage Loan
Program--Representations by Originators' and 'Descriptions of the
Securities--Assignment of Mortgage Loans' above. In general, if a class of
Securities is purchased at initial issuance at a premium and payments of
principal on the related Mortgage Loans occur at a rate faster than anticipated
at the time of purchase, the purchaser's actual yield to maturity will be lower
than that assumed at the time of purchase. Conversely, if a class of Securities
is purchased at initial issuance at a discount and payments of principal on the
related Mortgage Loans occur at a rate slower than that assumed at the time of
purchase, the purchaser's actual yield to maturity will be lower than that
originally anticipated. The effect of principal prepayments, liquidations and
purchases on yield will be particularly
 
                                       62

significant in the case of a series of Securities having a class entitled to
payments of interest only or to payments of interest that are disproportionately
high relative to the principal payments to which such class is entitled. Such a
class likely will be sold at a substantial premium to its principal balance, if
any, and any faster than anticipated rate of prepayments will adversely affect
the yield to holders thereof. In certain circumstances, rapid prepayments may
result in the failure of such holders to recoup their original investment. In
addition, the yield to maturity on certain other types of classes of Securities,
including Accrual Securities or certain other classes in a series including more
than one class of Securities, may be relatively more sensitive to the rate of
prepayment on the related Mortgage Loans than other classes of Securities.
 
     The timing of changes in the rate of principal payments on or repurchases
of the Mortgage Loans may significantly affect an investor's actual yield to
maturity, even if the average rate of principal payments experienced over time
is consistent with an investor's expectation. In general, the earlier a
prepayment of principal on the underlying Mortgage Loans or a repurchase
thereof, the greater will be the effect on an investor's yield to maturity. As a
result, the effect on an investor's yield of principal payments and repurchases
occurring at a rate higher (or lower) than the rate anticipated by the investor
during the period immediately following the issuance of a series of Securities
would not be fully offset by a subsequent like reduction (or increase) in the
rate of principal payments.
 
     The Mortgage Rates on certain ARM Loans subject to negative amortization
adjust monthly and their amortization schedules adjust less frequently. During a
period of rising interest rates as well as immediately after origination
(initial Mortgage Rates are generally lower than the sum of the Indices

applicable at origination and the related Note Margins) the amount of interest
accruing on the principal balance of such Mortgage Loans may exceed the amount
of the minimum scheduled monthly payment thereon. As a result, a portion of the
accrued interest on negatively amortizing Mortgage Loans may become Deferred
Interest that will be added to the principal balance thereof and will bear
interest at the applicable Mortgage Rate. The addition of any such Deferred
Interest to the principal balance will lengthen the weighted average life of the
Securities evidencing interests in such Mortgage Loans and may adversely affect
yield to holders thereof depending upon the price at which such Securities were
purchased. In addition, with respect to certain ARM Loans subject to negative
amortization, during a period of declining interest rates, it might be expected
that each minimum scheduled monthly payment on such a Mortgage Loan would exceed
the amount of scheduled principal and accrued interest on the principal balance
thereof, and since such excess will be applied to reduce such principal balance,
the weighted average life of such Securities will be reduced and may adversely
affect yield to holders thereof depending upon the price at which such
Securities were purchased.
 
     For each Mortgage Pool, if all necessary advances are made and if there is
no unrecoverable loss on any Mortgage Loan and if the related Credit Enhancer is
not in default under its obligations or other Credit Enhancement has not been
exhausted, the net effect of each distribution respecting interest will be to
pass-through to each holder of a class of Securities entitled to payments of
interest an amount which is equal to one month's interest (or, in the case of
quarterly-pay Securities, three month's interest or, in the case of semi-
annually-pay Securities, six months' interest) at the applicable Pass-Through
Rate on such class' principal balance or notional balance, as adjusted downward
to reflect any decrease in interest caused by any principal prepayments and the
addition of any Deferred Interest to the principal balance of any Mortgage Loan.
'Description of the Securities--Principal and Interest on the Securities.'
 
     With respect to certain of the ARM Loans, the Mortgage Rate at origination
may be below the rate that would result if the index and margin relating thereto
were applied at origination. Under the Sponsor's underwriting standards, the
Mortgagor under each Mortgage Loan will be qualified on the basis of the
Mortgage Rate in effect at origination. The repayment of any such Mortgage Loan
may thus be dependent on the ability of the Mortgagor to make larger level
monthly payments following the adjustment of the Mortgage Rate.
 
                     MATURITY AND PREPAYMENT CONSIDERATIONS
 
     As indicated above under 'The Mortgage Pools,' the original terms to
maturity of the Mortgage Loans in a given Mortgage Pool will vary depending upon
the type of Mortgage Loans included in such Mortgage Pool. The Prospectus
Supplement for a series of Securities will contain information with respect to
the types and maturities of the Mortgage Loans in the related Mortgage Pool.
Unless otherwise specified in the related Prospectus
 
                                       63

Supplement, all of the Mortgage Loans may be prepaid without penalty in full or
in part at any time. The prepayment experience with respect to the Mortgage
Loans in a Mortgage Pool will affect the maturity, average life and yield of the
related series of Securities.

 
     With respect to Balloon Loans, payment of the Balloon Amount (which, based
on the amortization schedule of such Mortgage Loans, may be a substantial
amount) will generally depend on the Mortgagor's ability to obtain refinancing
of such Mortgage Loan or to sell the Mortgaged Property prior to the maturity of
the Balloon Loan. The ability to obtain refinancing will depend on a number of
factors prevailing at the time refinancing or sale is required, including,
without limitation, real estate values, the Mortgagor's financial situation,
prevailing mortgage loan interest rates, the Mortgagor's equity in the related
Mortgaged Property, tax laws and prevailing general economic conditions. Unless
otherwise specified in the related Prospectus Supplement, neither the Sponsor,
the Master Servicer, nor any of their affiliates will be obligated to refinance
or repurchase any Mortgage Loan or to sell the Mortgaged Property.
 
     A number of factors, including homeowner mobility, economic conditions,
enforceability of due-on-sale clauses, mortgage market interest rates and the
availability of mortgage funds, affect prepayment experience. Unless otherwise
specified in the related Prospectus Supplement, the Mortgage Loans will
generally contain due-on-sale provisions permitting the mortgagee to accelerate
the maturity of the Mortgage Loan upon sale or certain transfers by the
Mortgagor of the underlying Mortgaged Property. Unless the related Prospectus
Supplement indicates otherwise, the Master Servicer will generally enforce any
due-on-sale clause to the extent it has knowledge of the conveyance or proposed
conveyance of the underlying Mortgaged Property and it is entitled to do so
under applicable law; provided, however, that the Master Servicer will not take
any action in relation to the enforcement of any due-on-sale provision which
would adversely affect or jeopardize coverage under any applicable insurance
policy. Certain ARM Loans may be assumable under certain conditions if the
proposed transferee of the related Mortgaged Property establishes its ability to
repay the Mortgage Loan and, in the reasonable judgment of the Master Servicer
or the related Sub-Servicer, the security for the ARM Loan would not be impaired
or might be improved by the assumption. The extent to which ARM Loans are
assumed by purchasers of the Mortgaged Properties rather than prepaid by the
related Mortgagors in connection with the sales of the Mortgaged Properties will
affect the weighted average life of the related series of Securities. See
'Description of the Securities--Collection and Other Servicing Procedures' and
'Certain Legal Aspects of the Mortgage Loans and Related Matters--Enforceability
of Certain Provisions' for a description of certain provisions of the Pooling
and Servicing Agreement and certain legal developments that may affect the
prepayment experience on the Mortgage Loans.
 
     There can be no assurance as to the rate of prepayment of the Mortgage
Loans. The Sponsor is not aware of any reliable, publicly available statistics
relating to the principal prepayment experience of diverse portfolios of
mortgage loans such as the Mortgage Loans over an extended period of time. All
statistics known to the Sponsor that have been compiled with respect to
prepayment experience on mortgage loans indicates that while some mortgage loans
may remain outstanding until their stated maturities, a substantial number will
be paid prior to their respective stated maturities.
 
     Although the Mortgage Rates on ARM Loans will be subject to periodic
adjustments, such adjustments will, unless otherwise specified in the related
Prospectus Supplement, (i) not increase or decrease such Mortgage Rates by more
than a fixed percentage amount on each adjustment date, (ii) not increase such

Mortgage Rates over a fixed percentage amount during the life of any ARM Loan
and (iii) be based on an index (which may not rise and fall consistently with
mortgage interest rates) plus the related Note Margin (which may be different
from margins being used at the time for newly originated adjustable rate
mortgage loans). As a result, the Mortgage Rates on the ARM Loans in a Mortgage
Pool at any time may not equal the prevailing rates for similar, newly
originated adjustable rate mortgage loans. In certain rate environments, the
prevailing rates on fixed-rate mortgage loans may be sufficiently low in
relation to the then-current Mortgage Rates on ARM Loans that the rate of
prepayment may increase as a result of refinancings. There can be no certainty
as to the rate of prepayments on the Mortgage Loans during any period or over
the life of any series of Securities.
 
     As may be described in the related Prospectus Supplement, the related
Pooling and Servicing Agreement may provide that all or a portion of the
principal collected on or with respect to the related Mortgage Loans may be
applied by the related Trustee to the acquisition of additional Mortgage Loans
during a specified period (rather
 
                                       64

than used to fund payments of principal to Securityholders during such period)
with the result that the related securities possess an interest-only period,
also commonly referred to as a revolving period, which will be followed by an
amortization period. Any such interest-only or revolving period may, upon the
occurrence of certain events to be described in the related Prospectus
Supplement, terminate prior to the end of the specified period and result in the
earlier than expected amortization of the related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to
being used to fund payments of principal to Securityholders.
 
     The result of such retention and temporary investment by the Trustee of
such principal would be to slow the amortization rate of the related Securities
relative to the amortization rate of the related Mortgage Loans, or to attempt
to match the amortization rate of the related Securities to an amortization
schedule established at the time such Securities are issued. Any such feature
applicable to any Securities may terminate upon the occurrence of events to be
described in the related Prospectus Supplement, resulting in the current funding
of principal payments to the related Securityholders and an acceleration of the
amortization of such Securities.
 
     Under certain circumstances, the Master Servicer, the Sponsor or, if
specified in the related Prospectus Supplement, the holders of the REMIC
Residual Securities or the Credit Enhancer may have the option to purchase the
Mortgage Loans in a Trust Estate. See 'The Pooling and Servicing
Agreement--Termination; Retirement of Securities.'
 
          CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS AND RELATED MATTERS
 
     The following discussion contains summaries of certain legal aspects of

mortgage loans that are general in nature. Because such legal aspects are
governed in part by applicable state law (which laws may differ substantially),
the summaries do not purport to be complete nor to reflect the laws of any
particular state nor to encompass the laws of all states in which the Mortgaged
Properties may be situated. The summaries are qualified in their entirety by
reference to the applicable federal and state laws governing the Mortgage Loans.
 
GENERAL
 
     The Mortgage Loans will be secured by either deeds of trust or mortgages,
depending upon the prevailing practice in the state in which the Mortgaged
Property subject to a Mortgage Loan is located. In some states, a mortgage
creates a lien upon the real property encumbered by the mortgage. In other
states, the mortgage conveys legal title to the property to the mortgagee
subject to a condition subsequent (i.e., the payment of the indebtedness secured
thereby). The mortgage is not prior to the lien for real estate taxes and
assessments and other charges imposed under governmental police powers. Priority
between mortgages depends on their terms in some cases or on the terms of
separate subordination or intercreditor agreements, and generally on the order
of recordation of the mortgage in the appropriate recording office. There are
two parties to a mortgage, the mortgagor, who is the borrower and homeowner, and
the mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. In the case of a land
trust, there are three parties because title to the property is held by a land
trustee under a land trust agreement of which the borrower is the beneficiary;
at origination of a mortgage loan, the borrower executes a separate undertaking
to make payments on the mortgage note. Although a deed of trust is similar to a
mortgage, a deed of trust has three parties; the borrower-homeowner 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. The trustee's authority under a deed of trust and the mortgagee's
authority under a mortgage are governed by law, the express provisions of the
deed of trust or mortgage, and, in some cases, the directions of the
beneficiary.
 
                                       65

COOPERATIVE LOANS
 
     If specified in the Prospectus Supplement relating to a series of
Securities, the Mortgage Loans also may consist of Cooperative Loans evidenced
by Cooperative Notes secured by security interests in shares issued by
cooperatives, which are private corporations that are entitled to be treated as
housing cooperatives under federal tax law, and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in the cooperatives' buildings. The security agreement will
create a lien upon, or grant a title interest in, the property which it covers,
the priority of which will depend on the terms of the particular security
agreement as well as the order of recordation of the agreement in the
appropriate recording office. Such a lien or title interest is not prior to the
lien for real estate taxes and assessments and other charges imposed under
governmental police powers.

 
     Each cooperative owns in fee or has a leasehold interest in all the real
property and owns in fee or leases the building and all separate dwelling units
therein. The cooperative is directly responsible for property management and, in
most cases, payment of real estate taxes, other governmental impositions and
hazard and liability insurance. If there is a blanket mortgage or mortgages on
the cooperative apartment building or underlying land, as is generally the case,
or an underlying lease of the land, as is the case in some instances, the
cooperative, as property mortgagor, or lessee, as the case may be, also is
responsible for meeting these mortgage or rental obligations. A blanket mortgage
is ordinarily incurred by the cooperative in connection with either the
construction or purchase of the cooperative's apartment building or the
obtaining of capital by the cooperative. The interest of the occupant under
proprietary leases or occupancy agreements as to which that cooperative is the
landlord generally is subordinate to the interest of the holder of a blanket
mortgage and to the interest of the holder of a land lease. If the cooperative
is unable to meet the payment obligations (i) arising under a blanket mortgage,
the mortgagee holding a blanket mortgage could foreclose on that mortgage and
terminate all subordinate proprietary leases and occupancy agreements or (ii)
arising under its land lease, the holder of the landlord's interest under the
land lease could terminate it and all subordinate proprietary leases and
occupancy agreements. Also, a blanket mortgage on a cooperative may provide
financing in the form of a mortgage that does not fully amortize, with a
significant portion of principal being due in one final payment at maturity. The
inability of the cooperative to refinance a mortgage and its consequent
inability to make such final payment could lead to foreclosure by the mortgagee.
Similarly, a land lease has an expiration date and the inability of the
cooperative to extend its term or, in the alternative, to purchase the land
could lead to termination of the cooperative's interest in the property and
termination of all proprietary leases and occupancy agreements. In either event,
a foreclosure by the holder of a blanket mortgage or the termination of the
underlying lease could eliminate or significantly diminish the value of any
collateral held by the lender who financed the purchase by an individual
tenant-stockholder of cooperative shares or, in the case of the Mortgage Loans,
the collateral securing the Cooperative Loans.
 
     The cooperative is owned by tenant-stockholders who, through ownership of
stock or shares in the corporation, receive proprietary leases or occupancy
agreements that confer exclusive rights to occupy specific units. Generally, a
tenant-stockholder of a cooperative must make a monthly payment to the
cooperative representing such tenant-stockholder's pro rata share of the
cooperative's payments for its blanket mortgage, real property taxes,
maintenance expenses and other capital or ordinary expenses. An ownership
interest in a cooperative and accompanying occupancy rights are financed through
a cooperative share loan evidenced by a promissory note and secured by an
assignment of and a security interest in the occupancy agreement or proprietary
lease and a security interest in the related cooperative shares. The lender
generally takes possession of the share certificate and a counterpart of the
proprietary lease or occupancy agreement and a financing statement covering the
proprietary lease or occupancy agreement and the cooperative shares is filed in
the appropriate state and local offices to perfect the lender's interest in its
collateral. Subject to the limitations discussed below, upon default of the
tenant-stockholder, the lender may sue for judgment on the promissory note,
dispose of the collateral at a public or private sale or otherwise proceed

against the collateral or tenant-stockholder as an individual as provided in the
security agreement covering the assignment of the proprietary lease or occupancy
agreement and the pledge of cooperative shares. See 'Foreclosure on Shares of
Cooperatives' below.
 
                                       66

FORECLOSURE
 
     Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale (private sale) under a specific provision in the deed of trust
and state laws which authorize the trustee to sell the property upon any default
by the borrower under the terms of the note or deed of trust. Beside the
nonjudicial remedy, a deed of trust may be judicially foreclosed. In addition to
any notice requirements contained in a deed of trust, in some states, the
trustee must record a notice of default and within a certain period of time send
a copy to the borrower trustor and to any person who has recorded a request for
a copy of notice of default and notice of sale. In addition, the trustee must
provide notice in some states to any other individual having an interest of
record in the real property, including any junior lienholders. If the deed of
trust is not reinstated within a specified period, a notice of sale must be
posted in a public place and, in most states, published for a specific period of
time in one or more local 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.
 
     Foreclosure of a mortgage is generally accomplished by judicial action.
Generally, the action is initiated by the service of legal pleadings upon all
parties having an interest of record in the real property. Delays in completion
of the foreclosure may occasionally result from difficulties in locating
necessary parties. Judicial foreclosure proceedings are often not contested by
any of the applicable parties. If the mortgagee's right to foreclose is
contested, the legal proceedings necessary to resolve the issue can be
time-consuming.
 
     In some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In general,
in such states, the borrower, or any other person having a junior encumbrance on
the real estate, may, during a reinstatement period, cure the default by paying
the entire amount in arrears plus the costs and expenses incurred in enforcing
the obligation.
 
     In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the referee or other designated officer or by the trustee is a public
sale. However, because of the difficulty a potential buyer at the sale would
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it is
uncommon for a third party to purchase the property at a foreclosure sale unless
there is a great deal of economic incentive for the new purchaser to purchase
the subject property at the sale. Rather, it is common for the lender to
purchase the property from the trustee or referee for a credit bid less than or
equal to the unpaid principal amount of the mortgage or deed of trust, accrued
and unpaid interest and the expense of foreclosure. Generally, state law
controls the amount of foreclosure costs and expenses, including attorneys'

fees, which may be recovered by a lender. Thereafter, subject to the right of
the borrower in some states to remain in possession during the redemption
period, the lender will assume the burdens of ownership, including obtaining
hazard insurance and making such 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 and, in some states, the lender may be entitled to a deficiency
judgment. Any loss may be reduced by the receipt of any mortgage insurance
proceeds.
 
FORECLOSURE ON SHARES OF COOPERATIVES
 
     The cooperative shares and proprietary lease or occupancy agreement 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 by-laws, as well as in the proprietary lease or
occupancy agreement. The proprietary lease or occupancy agreement, even while
pledged, may be cancelled by the cooperative for 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. Commonly, rent and other
obligations and charges arising under a proprietary lease or occupancy agreement
that are owed to the cooperative are made liens upon the shares to which the
proprietary lease or occupancy agreement relates. In addition, the proprietary
lease or occupancy agreement generally permits the cooperative to terminate such
lease or agreement in the event the borrower defaults in the performance of
covenants thereunder. Typically, the lender and the cooperative enter into a
recognition agreement that, together with any lender protection provisions
contained in the proprietary lease, establishes the rights and obligations of
both parties in the event of a default by
 
                                       67

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 usually will 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 notice of and an opportunity
to cure the default. The recognition agreement typically provides that if the
proprietary lease or occupancy agreement is terminated, the cooperative will
recognize the lender's lien against proceeds from a sale of the cooperative
apartment, subject, however, to the cooperative's right to sums due under such
proprietary lease or occupancy agreement or sums that have become liens on the
shares relating to the proprietary lease or occupancy agreement. The total
amount owed to the cooperative by the tenant-stockholder, which the lender
generally cannot restrict and does not monitor, could reduce the amount realized
upon a sale of the collateral below the outstanding principal balance of the
Cooperative Loan and accrued and unpaid interest thereon.

 
     Recognition agreements generally 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-stockholder.
 
     In New York, foreclosure on the cooperative shares is accomplished by
public sale in accordance with the provisions of Article 9 of the UCC and the
security agreement relating to those shares. Article 9 of the UCC requires that
a sale be conducted in a 'commercially reasonable' manner. Whether a sale has
been conducted in a 'commercially reasonable' manner will depend on the facts in
each case. In determining commercial reasonableness, a court will look to the
notice given the debtor and the method, manner, time, place and terms of the
sale and the sale price. Generally, a sale conducted according to the usual
practice of banks selling similar collateral will be considered reasonably
conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the cooperative corporation to receive sums due under
the proprietary lease or occupancy agreement. If there are proceeds remaining,
the lender must account to the tenant-stockholder for the surplus. Conversely,
if a portion of the indebtedness remains unpaid, the tenant-stockholder is
generally responsible for the deficiency. See 'Anti-Deficiency Legislation and
Other Limitations on Lenders' below.
 
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 or other parties are given
a statutory period in which to redeem the property from the foreclosure sale. In
some states, redemption may occur only upon payment of the entire principal
balance of the loan, accrued interest and expenses of foreclosure. 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 rights of
redemption would defeat the title of any purchaser subsequent to foreclosure or
sale under a deed of trust. Consequently, the practical effect of the redemption
right is to force the lender to maintain the property and pay the expenses of
ownership until the redemption period has expired. In some states, there is no
right to redeem property after a trustee's sale under a deed of trust.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS
 
     Certain states have imposed statutory prohibitions that limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage. In some
states, including California, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure. A deficiency judgment is a personal judgment against the former
borrower equal in most cases to the difference between the amount due to the

lender and the net amount realized upon the public sale of the real property. In
the case of a Mortgage Loan secured by a property owned by a trust where the
Mortgage Note is executed on behalf of the trust, a deficiency judgment against
the trust following foreclosure or sale under a deed of trust, even if
 
                                       68

obtainable under applicable law, may be of little value to the mortgagee or
beneficiary if there are no trust assets against which such deficiency judgment
may be executed. Other statutes require the beneficiary or mortgagee to exhaust
the security af forded 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 such
security; however, in some of these states the lender, 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, in those states permitting
such election, is that lenders will usually proceed against the security first
rather than bringing a personal action against the borrower. Finally, in certain
other states, statutory provisions limit any deficiency judgment against the
former borrower following a foreclosure to the excess of the outstanding debt
over the fair value of the property at the time of the public sale. The purpose
of these statutes is generally to prevent a beneficiary or mortgagee from
obtaining a large deficiency judgment against the former borrower as a result of
low or no bids at the judicial sale.
 
     In addition to laws limiting or prohibiting deficiency judgments, numerous
other federal and state statutory provisions, including the federal bankruptcy
laws and state laws affording relief to debtors, may interfere with or affect
the ability of the secured mortgage lender to realize upon collateral or enforce
a deficiency judgment. For example, with respect to federal bankruptcy law, a
court with federal bankruptcy jurisdiction may permit a debtor through his or
her Chapter 11 or Chapter 13 rehabilitative plan to cure a monetary default in
respect of a mortgage loan on a debtor's residence by paying arrearages within a
reasonable time period and reinstating the original mortgage loan payment
schedule even though the lender accelerated the mortgage loan and final judgment
of foreclosure had been entered in state court (provided no sale of the
residence had yet occurred) prior to the filing of the debtor's petition. Some
courts with federal bankruptcy jurisdiction have approved plans, based on the
particular facts of the reorganization case, that effected the curing of a
mortgage loan default by paying arrearages over a number of years.
 
     Courts with federal bankruptcy jurisdiction also have indicated that the
terms of a mortgage loan secured by property of the debtor may be modified.
These courts have allowed modifications that include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
forgiving all or a portion of the debt and reducing the lender's security
interest to the value of the residence, thus leaving the lender a general
unsecured creditor for the difference between the value of the residence and the
outstanding balance of the loan.
 
     Certain states have imposed general equitable principles upon judicial
foreclosure. These equitable principles are generally designed to relieve the

borrower from the legal effect of the borrower's default under the related loan
documents. Examples of judicial remedies that have been fashioned include
judicial requirements that the lender undertake affirmative and expensive
actions to determine the causes for the borrower's default and the likelihood
that the borrower will be able to reinstate the loan. In some cases, lenders
have been required to reinstate loans or recast payment schedules in order to
accommodate borrowers who are suffering from temporary financial disabilities.
In other cases, such courts have limited the right of the lender to foreclose if
the default under the loan is not monetary, such as the borrower failing to
adequately maintain the property or the borrower executing a second deed of
trust affecting the property.
 
     Certain tax liens arising under the Internal Revenue Code of 1986, as
amended, may in certain circumstances provide priority over the lien of a
mortgage or deed of trust. In addition, substantive requirements are imposed
upon mortgage lenders in connection with the origination and the servicing of
mortgage loans by numerous federal and some state consumer protection laws.
These laws include, by example, the federal Truth-in-Lending Act, Real Estate
Settlement Procedures Act, Equal Credit Opportunity Act, Fair Credit Billing
Act, Fair Credit Reporting Act and related statutes and the California Fair Debt
Collection Practices Act. These laws and regulations impose specific statutory
liabilities upon lenders who originate mortgage loans and fail to comply with
the provisions of the law. In some cases, this liability may affect assignees of
the mortgage loans.
 
ENVIRONMENTAL LEGISLATION
 
     Certain states impose a statutory lien for associated costs on property
that is the subject of a cleanup action by the state on account of hazardous
wastes or hazardous substances released or disposed of on the property. Such a
lien generally will have priority over all subsequent liens on the property and,
in certain of these states, will have priority over prior recorded liens
including the lien of a mortgage. In some states, however, such a lien
 
                                       69

will not have priority over prior recorded liens of a deed of trust. In
addition, under federal environmental legislation and under state law in a
number of states, a secured party which takes a deed in lieu of foreclosure or
acquires a mortgaged property at a foreclosure sale or assumes active control
over the operation or management of a property so as to be deemed an 'owner' or
'operator' of the property may be liable for the costs of cleaning up a
contaminated site. Although such costs could be substantial, it is unclear
whether they would be imposed on a lender (such as a Trust Estate) secured by
residential real property. In the event that title to a Mortgaged Property
securing a Mortgage Loan in a Trust Estate was acquired by the Trust and cleanup
costs were incurred in respect of the Mortgaged Property, the holders of the
related series of Securities might realize a loss if such costs were required to
be paid by the Trust.
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
     Unless the Prospectus Supplement indicates otherwise, generally all of the
Mortgage Loans contain due-on-sale clauses. These clauses permit the lender to

accelerate the maturity of the loan if the borrower sells, transfers or conveys
the property. The enforceability of these clauses has been the subject of
legislation or litigation in many states including California, and in some cases
the enforceability of these clauses was limited or denied. However, the Garn-St.
Germain Depository Institutions Act of 1982 (the 'Garn-St. Germain Act')
preempts state constitutional, statutory and case law that prohibits the
enforcement of due-on-sale clauses and permits lenders to enforce these clauses
in accordance with their terms, subject to certain limited exceptions. The
Garn-St. Germain Act does 'encourage' lenders to permit assumption of loans at
the original rate of interest or at some other rate less than the average of the
original rate and the market rate.
 
     The Garn-St. Germain Act also sets forth nine specific instances in which a
mortgage lender covered by the Garn-St. Germain Act may not exercise a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have occurred. These include intra-family transfers, certain transfers by
operation of law, leases of fewer than three years and the creation of a junior
encumbrance. Regulations promulgated under the Garn-St. Germain Act also
prohibit the imposition of a prepayment penalty upon the acceleration of a loan
pursuant to a due-on-sale clause.
 
     The inability to enforce a due-on-sale clause may result in a mortgage loan
bearing an interest rate below the current market rate being assumed by a new
home buyer rather than being paid off, that may have an impact upon the average
life of the Mortgage Loans and the number of Mortgage Loans that may be
outstanding until maturity.
 
     Upon foreclosure, courts have imposed general equitable principles. These
equitable principles generally are designed to relieve the borrower from the
legal effect of his defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have substituted their judgment for
the lender's judgment and have required that lenders reinstate loans or recast
payment schedules in order to accommodate borrowers who are suffering from
temporary financial disability. In other cases, courts have limited the right of
the lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower failing to adequately maintain the property or
the borrower executing a second mortgage or deed of trust affecting the
property. Finally, some courts have been faced with the issue of whether or not
federal or state constitutional provisions reflecting due process concerns for
adequate notice require that borrowers under deeds of trust or mortgages receive
notices in addition to the statutorily prescribed minimum. For the most part,
these cases have upheld the notice provisions as being reasonable or have found
that the sale by a trustee under a deed of trust, or under a mortgage having a
power of sale, does not involve sufficient state action to afford constitutional
protections to the borrower.
 
CERTAIN PROVISIONS OF CALIFORNIA DEEDS OF TRUST
 
     Most institutional lenders in California use a form of deed of trust that
confers on the beneficiary the right both to receive all proceeds collected
under any hazard insurance policy and all awards made in connection with any

condemnation proceedings, and to apply such proceeds and awards to any
indebtedness secured by the deed of trust, in such order as the beneficiary may
determine, provided, however, that California law prohibits the beneficiary from
applying insurance and condemnation proceeds to the indebtedness secured by the
deed of trust unless the beneficiary's security has been impaired by the
casualty or condemnation, and, if such security has
 
                                       70

been impaired, permits such proceeds to be so applied only to the extent of such
impairment. 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, and, as a result thereof, the beneficiary's security is impaired,
the beneficiary under the underlying first deed of trust 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 first deed of trust. Proceeds in excess
of the amount of indebtedness secured by a first deed of trust will, in most
cases, be applied to the indebtedness of a junior deed of trust.
 
     Another provision typically found in the forms of deed of trust used by
most institutional lenders in California obligates the trustor 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 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 beneficiary under the deed of trust. Upon a failure of the
trustor to perform any of these obligations, the beneficiary is given the right
under the deed of trust to perform the obligation itself, at its election, with
the trustor agreeing to reimburse the beneficiary for any sums expended by the
beneficiary on behalf of the trustor. All sums so expended by the beneficiary
become part of the indebtedness secured by the deed of trust.
 
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. A similar federal statute
was in effect with respect to mortgage loans made during the first three months
of 1980. The Office of Thrift Supervision is authorized to issue rules and
regulations and to publish interpretations governing implementation of Title V.
The statute authorized any state to reimpose interest rate limits by adopting,
before April 1, 1983, a law or constitutional provision which expressly rejects
application of the federal law. In addition, even where Title V is not so
rejected, any state is authorized by the law to adopt a provision limiting
discount points or other charges on mortgage loans covered by Title V. Certain
states have taken action to reimpose interest rate limits or to limit discount
points or other charges.
 
     As indicated above under 'Mortgage Loan Program--Representations by
Originators,' each Originator of a Mortgage Loan will have represented that such
Mortgage Loan was originated in compliance with then applicable state laws,

including usury laws, in all material respects. However, the Mortgage Rates on
the Mortgage Loans will be subject to applicable usury laws as in effect from
time to time.
 
ALTERNATIVE MORTGAGE INSTRUMENTS
 
     Alternative mortgage instruments, including ARM Loans and early ownership
mortgage loans, originated by non-federally chartered lenders have historically
been subjected to a variety of restrictions. Such restrictions differed from
state to state, resulting in difficulties in determining whether a particular
alternative mortgage instrument originated by a state-chartered lender was in
compliance with applicable law. These difficulties were alleviated substantially
as a result of the enactment of Title VIII of the Garn-St. Germain Act ('Title
VIII'). Title VIII provides that: notwithstanding any state law to the contrary,
state-chartered banks may originate alternative mortgage instruments in
accordance with regulations promulgated by the Comptroller of the Currency with
respect to origination of alternative mortgage instruments by national banks;
state-chartered credit unions may originate alternative mortgage instruments in
accordance with regulations promulgated by the National Credit Union
Administration with respect to origination of alternative mortgage instruments
by federal credit unions; and all other non-federally chartered housing
creditors, including state-chartered savings and loan associations,
state-chartered savings banks and mutual savings banks and mortgage banking
companies, may originate alternative mortgage instruments in accordance with the
regulations promulgated by the Federal Home Loan Bank Board, predecessor to the
Office of Thrift Supervision, with respect to origination of alternative
mortgage instruments by federal savings and loan associations. Title VIII
provides that any state may reject applicability of the provisions of Title VIII
by adopting, prior to October 15, 1985, a law or constitutional provision
expressly rejecting the applicability of such provisions. Certain states have
taken such action.
 
                                       71

SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940
 
     Under the terms of the Soldiers' and Sailors' Civil Relief Act of 1940, as
amended (the 'Relief Act'), a Mortgagor who enters military service after the
origination of such Mortgagor's Mortgage Loan (including a Mortgagor who was in
reserve status and is called to active duty after origination of the Mortgage
Loan), may not be charged interest (including fees and charges) above an annual
rate of 6% during the period of such Mortgagor's active duty status, unless a
court orders otherwise upon application of the lender. The Relief Act applies to
Mortgagors who are members of the Army, Navy, Air Force, Marines, National
Guard, Reserves, Coast Guard, and officers of the U.S. Public Health Service
assigned to duty with the military. Because the Relief Act applies to Mortgagors
who enter military service (including reservists who are called to active duty)
after origination of the related Mortgage Loan, no information can be provided
as to the number of loans that may be affected by the Relief Act. Application of
the Relief Act would adversely affect, for an indeterminate period of time, the
ability of the Master Servicer to collect full amounts of interest on certain of
the Mortgage Loans. Any shortfall in interest collections resulting from the
application of the Relief Act or similar legislation or regulations, which would
not be recoverable from the related Mortgage Loans, would result in a reduction

of the amounts distributable to the holders of the related Securities, and would
not be covered by advances, any Letter of Credit or any other form of Credit
Enhancement provided in connection with the related series of Securities. In
addition, the Relief Act imposes limitations that would impair the ability of
the Master Servicer to foreclose on an affected Mortgage Loan during the
Mortgagor's period of active duty status, and, under certain circumstances,
during an additional three month period thereafter. Thus, in the event that the
Relief Act or similar legislation or regulations apply to any Mortgage Loan
which goes into default, there may be delays in payment and losses on the
related Securities in connection therewith. Any other interest shortfalls,
deferrals or forgiveness of payments on the Mortgage Loans resulting from
similar legislation or regulations may result in delays in payments or losses to
Securityholders of the related series.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a general discussion of the material anticipated federal
income tax consequences to investors of the purchase, ownership and disposition
of the Securities offered hereby. The discussion is based upon laws,
regulations, rulings and decisions now in effect, all of which are subject to
change. The discussion below does not purport to deal with all federal tax
consequences applicable to all categories of investors, some of which may be
subject to special rules. 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.
 
     The following discussion addresses securities of three general types: (i)
securities ('Grantor Trust Securities') representing interests in a Trust Estate
(a 'Grantor Trust Estate') which the Sponsor will covenant not to elect to have
treated as a real estate mortgage investment conduit (REMIC); (ii) securities
('REMIC Securities') representing interests in a Trust Estate, or a portion
thereof, which the Sponsor will covenant to elect to have treated as a REMIC
under sections 860A through 860G of the Internal Revenue Code of 1986, as
amended (the 'Code'); and (iii) securities ('Debt Securities') that are intended
to be treated for federal income tax purposes as indebtedness secured by the
underlying Mortgage Loans. This Prospectus does not address the tax treatment of
partnership interests. Such a discussion will be set forth in the related
Prospectus Supplement for any Trust issuing Securities characterized as
partnership interests. The Prospectus Supplement for each series of Securities
will indicate whether a REMIC election (or elections) will be made for the
related Trust Estate and, if a REMIC election is to be made, will identify all
'regular interests' and 'residual interests' in the REMIC. For purposes of this
discussion, references to a 'Securityholder' or a 'Holder' are to the beneficial
owner of a Security.
 
GRANTOR TRUST SECURITIES
 
     With respect to each series of Grantor Trust Securities, Dewey Ballantine,
special tax counsel to the Sponsor, will deliver its opinion to the Sponsor that
(unless otherwise limited in the related Prospectus Supplement) the related
Grantor Trust Estate will be classified as a grantor trust and not as a
partnership or an association taxable as a corporation. Accordingly, each Holder

of a Grantor Trust Security will generally be treated as the owner of an
interest in the Mortgage Loans included in the Grant or Trust Estate.
 
                                       72

     For purposes of the following discussion, a Grantor Trust Security
representing an undivided equitable ownership interest in the principal of the
Mortgage Loans constituting the related Grantor Trust Estate, together with
interest thereon at a pass-through rate, will be referred to as a 'Grantor Trust
Fractional Interest Security.' A Grantor Trust Security representing ownership
of all or a portion of the difference between interest paid on the Mortgage
Loans constituting the related Grantor Trust Estate and interest paid to the
Holders of Grantor Trust Fractional Interest Securities issued with respect to
such Grantor Trust Estate will be referred to as a 'Grantor Trust Strip
Security.'
 
  Special Tax Attributes
 
     Unless otherwise disclosed in a related Prospectus Supplement, Dewey
Ballantine, special tax counsel to the Sponsor, will deliver its opinion to the
Sponsor that (a) Grantor Trust Fractional Interest Securities will represent
interests in (i) 'qualifying real property loans' within the meaning of section
593(d) of the Code; (ii) 'loans . . . secured by an interest in real property'
within the meaning of section 7701(a)(19)(C)(v) of the Code; and (iii)
'obligations (including any participation or certificate of beneficial ownership
therein) which . . . are principally secured by an interest in real property'
within the meaning of section 860G(a)(3)(A) of the Code; and (b) interest on
Grantor Trust Fractional Interest Securities will be considered 'interest on
obligations secured by mortgages on real property or on interests in real
property' within the meaning of section 856(c)(3)(B) of the Code. In addition,
the Grantor Trust Strip Securities will be 'obligations (including any
participation or certificate of beneficial ownership therein) . . . principally
secured by an interest in real property' within the meaning of section
860G(a)(3)(A) of the Code.
 
  Taxation of Holders of Grantor Trust Securities
 
     Holders of Grantor Trust Fractional Interest Securities generally will be
required to report on their federal income tax returns their respective shares
of the income from the Mortgage Loans (including amounts used to pay reasonable
servicing fees and other expenses but excluding amounts payable to Holders of
any corresponding Grantor Trust Strip Securities) and, subject to the
limitations described below, will be entitled to deduct their shares of any such
reasonable servicing fees and other expenses. If a Holder acquires a Grantor
Trust Fractional Interest Security for an amount that differs from its
outstanding principal amount, the amount includible in income on a Grantor Trust
Fractional Interest Security may differ from the amount of interest
distributable thereon. See 'Discount and Premium,' below. Individuals holding a
Grantor Trust Fractional Interest Security directly or through certain
pass-through entities will be allowed a deduction for such reasonable servicing
fees and expenses only to the extent that the aggregate of such Holder's
miscellaneous itemized deductions exceeds 2% of such Holder's adjusted gross
income. Further, Holders (other than corporations) subject to the alternative
minimum tax may not deduct miscellaneous itemized deductions in determining

alternative minimum taxable income.
 
     Holders of Grantor Trust Strip Securities generally will be required to
treat such Securities as 'stripped coupons' under section 1286 of the Code.
Accordingly, such a Holder will be required to treat the excess of the total
amount of payments on such a Security over the amount paid for such Security as
original issue discount and to include such discount in income as it accrues
over the life of such Security. See '--Discount and Premium,' below.
 
     Grantor Trust Fractional Interest Securities may also be subject to the
coupon stripping rules if a class of Grantor Trust Strip Securities is issued as
part of the same series of Securities. The consequences of the application of
the coupon stripping rules would appear to be that any discount arising upon the
purchase of such a Security (and perhaps all stated interest thereon) would be
classified as original issue discount and includible in the Holder's income as
it accrues (regardless of the Holder's method of accounting), as described below
under '--Discount and Premium.' The coupon stripping rules will not apply,
however, if (i) the pass-through rate is no more than 100 basis points lower
than the gross rate of interest payable on the underlying Mortgage Loans and
(ii) the difference between the outstanding principal balance on the Security
and the amount paid for such Security is less than 0.25% of such principal
balance times the weighted average remaining maturity of the Security.
 
                                       73



  Sales of Grantor Trust Securities
 
     Any gain or loss recognized on the sale of a Grantor Trust Security (equal
to the difference between the amount realized on the sale and the adjusted basis
of such Grantor Trust Security) will be capital gain or loss, except to the
extent of accrued and unrecognized market discount, which will be treated as
ordinary income, and in the case of banks and other financial institutions
except as provided under section 582(c) of the Code. The adjusted basis of a
Grantor Trust Security will generally equal its cost, increased by any income
reported by the seller (including original issue discount and market discount
income) and reduced (but not below zero) by any previously reported losses, any
amortized premium and by any distributions of principal.
 
  Grantor Trust Reporting
 
     The Trustee will furnish to each Holder of a Grantor Trust Fractional
Interest Security with each distribution a statement setting forth the amount of
such distribution allocable to principal on the underlying Mortgage Loans and to
interest thereon at the related Pass-Through Rate. In addition, within a
reasonable time after the end of each calendar year, based on information
provided by the Servicer, the Trustee will furnish to each Holder during such
year such customary factual information as the Servic er deems necessary or
desirable to enable Holders of Grantor Trust Securities to prepare their tax
returns and will furnish comparable information to the Internal Revenue Service
(the 'IRS') as and when required to do so by law.
 
REMIC SECURITIES

 
     If provided in a related Prospectus Supplement, an election will be made to
treat a Trust Estate as a REMIC under the Code. Qualification as a REMIC
requires ongoing compliance with certain conditions. With respect to each series
of Securities for which such an election is made, Dewey Ballantine, special tax
counsel to the Sponsor, will deliver its opinion to the Sponsor that (unless
otherwise limited in the related Prospectus Supplement), assuming compliance
with the Pooling and Servicing Agreement, the Trust Estate will be treated as a
REMIC for federal income tax purposes. A Trust Estate for which a REMIC election
is made will be referred to herein as a 'REMIC Trust.' The Securities of each
class will be designated as 'regular interests' in the REMIC Trust except that a
separate class will be designated as the 'residual interest' in the REMIC Trust.
The Prospectus Supplement for each series of Securities will state whether
Securities of each class will constitute a regular interest (a REMIC Regular
Security) or a residual interest (a REMIC Residual Security).
 
     A REMIC Trust will not be subject to federal income tax except with respect
to income from prohibited transactions and in certain other instances described
below. See '--Taxes on a REMIC Trust.' Generally, the total income from the
Mortgage Loans in a REMIC Trust will be taxable to the Holders of the Securities
of that series, as described below.
 
     Regulations issued by the Treasury Department on December 23, 1992 (the
'REMIC Regulations') provide some guidance regarding the federal income tax
consequences associated with the purchase, ownership and disposition of REMIC
Securities. While certain material provisions of the REMIC Regulations are
discussed below, investors should consult their own tax advisors regarding the
possible application of the REMIC Regulations in their specific circumstances.
 
SPECIAL TAX ATTRIBUTES
 
     REMIC Regular Securities and REMIC Residual Securities will be 'regular or
residual interests in a REMIC' within the meaning of section 7701(a)(19)(C)(xi)
of the Code, 'qualifying real property loans' within the meaning of section
593(d) of the Code and 'real estate assets' within the meaning of section
856(c)(5)(A) of the Code. If at any time during a calendar year less than 95% of
the assets of a REMIC Trust consist of 'qualified mortgages' (within the meaning
of section 860G(a)(3) of the Code) then the portion of the REMIC Regular
Securities and REMIC Residual Securities that are qualifying assets under those
sections during such calendar year may be limited to the portion of the assets
of such REMIC Trust that are qualified mortgages. Similarly, income on the REMIC
Regular Securities and REMIC Residual Securities will be treated as 'interest on
obligations secured by mortgages on real property' within the meaning of section
856(c)(3)(B) of the Code, subject to the same limitation as set forth in the
preceding sentence. For purposes of applying this limitation, a REMIC Trust
should be treated as owning the assets represented by the qualified mortgages.
The assets of the
 
                                       74

Trust Estate will include, in addition to the Mortgage Loans, payments on the
Mortgage Loans held pending distribution on the REMIC Regular Securities and
REMIC Residual Securities and any reinvestment income thereon. REMIC Regular
Securities and REMIC Residual Securities held by a financial institution to

which section 585, 586 or 593 of the Code applies will be treated as evidences
of indebtedness for purposes of section 582(c)(1) of the Code. REMIC Regular
Securities will also be qualified mortgages with respect to other REMICs.
 
  Taxation of Holders of REMIC Regular Securities
 
     Except as indicated below in this federal income tax discussion, the REMIC
Regular Securities will be treated for federal income tax purposes as debt
instruments issued by the REMIC Trust on the date such Securities are first sold
to the public (the 'Settlement Date') and not as ownership interests in the
REMIC Trust or its assets. Holders of REMIC Regular Securities that otherwise
report income under a cash method of accounting will be required to report
income with respect to such Securities under an ac crual method. For additional
tax consequences relating to REMIC Regular Securities purchased at a discount or
with premium, see '--Discount and Premium,' below.
 
  Taxation of Holders of REMIC Residual Securities
 
     Daily Portions.  Except as indicated below, a Holder of a REMIC Residual
Security for a REMIC Trust generally will be required to report its daily
portion of the taxable income or net loss of the REMIC Trust for each day during
a calendar quarter that the Holder owned such REMIC Residual Security. For this
purpose, the daily portion shall be determined by allocating to each day in the
calendar quarter its ratable portion of the taxable income or net loss of the
REMIC Trust for such quarter and by allocating the amount so allocated among the
Residual Holders (on such day) in accordance with their percentage interests on
such day. Any amount included in the gross income or allowed as a loss of any
Residual Holder by virtue of this paragraph will be treated as ordinary income
or loss.
 
     The requirement that each Holder of a REMIC Residual Security report its
daily portion of the taxable income or net loss of the REMIC Trust will continue
until there are no Securities of any class outstanding, even though the Holder
of the REMIC Residual Security may have received full payment of the stated
interest and principal on its REMIC Residual Security.
 
     The Trustee will provide to Holders of REMIC Residual Securities of each
series of Securities (i) such information as is necessary to enable them to
prepare their federal income tax returns and (ii) any reports regarding the
Securities of such series that may be required under the Code.
 
     Taxable Income or Net Loss of a REMIC Trust.  The taxable income or net
loss of a REMIC Trust will be the income from the qualified mortgages it holds
and any reinvestment earnings less deductions allowed to the REMIC Trust. Such
taxable income or net loss for a given calendar quarter will be determined in
the same manner as for an individual having the calendar year as the taxable
year and using the accrual method of accounting, with certain modifications. The
first modification is that a deduction will be allowed for accruals of interest
(including any original issue discount, but without regard to the investment
interest limitation in section 163(d) of the Code) on the REMIC Regular
Securities (but not the REMIC Residual Securities), even though REMIC Regular
Securities are for non-tax purposes evidences of beneficial ownership rather
than indebtedness of a REMIC Trust. Second, market discount or premium equal to
the difference between the total stated principal balances of the qualified

mortgages and the basis to the REMIC Trust therein generally will be included in
income (in the case of discount) or deductible (in the case of premium) by the
REMIC Trust as it accrues under a constant yield method, taking into account the
'Prepayment Assumption' (as defined in the Related Prospectus Supplement, see
'--Discount and Premium--Original Issue Discount,' below). The basis to a REMIC
Trust in the qualified mortgages is the aggregate of the issue prices of all the
REMIC Regular Securities and REMIC Residual Securities in the REMIC Trust on the
Settlement Date. If, however, a substantial amount of a class of REMIC Regular
Securities or REMIC Residual Securities has not been sold to the public, then
the fair market value of all the REMIC Regular Securities or REMIC Residual
Securities in that class as of the date of the Prospectus Supplement should be
substituted for the issue price.
 
     Third, no item of income, gain, loss or deduction allocable to a prohibited
transaction (see '--Taxes on a REMIC Trust--Prohibited Transactions' below) will
be taken into account. Fourth, a REMIC Trust generally
 
                                       75

may not deduct any item that would not be allowed in calculating the taxable
income of a partnership by virtue of section 703(a)(2) of the Code. Finally, the
limitation on miscellaneous itemized deductions imposed on individuals by
section 67 of the Code will not be applied at the REMIC Trust level to any
servicing and guaranty fees. (See, however, '--Pass-Through of Servicing and
Guaranty Fees to Individuals' below.) In addition, under the REMIC Regulations,
any expenses that are incurred in connection with the formation of a REMIC Trust
and the issuance of the REMIC Regular Securities and REMIC Residual Securities
are not treated as expenses of the REMIC Trust for which a deduction is allowed.
If the deductions allowed to a REMIC Trust exceed its gross income for a
calendar quarter, such excess will be a net loss for the REMIC Trust for that
calendar quarter. The REMIC Regulations also provide that any gain or loss to a
REMIC Trust from the disposition of any asset, including a qualified mortgage or
'permitted investment' (as defined in section 860G(a)(5) of the Code) will be
treated as ordinary gain or loss.
 
     A Holder of a REMIC Residual Security may be required to recognize taxable
income without being entitled to receive a corresponding amount of cash. This
could occur, for example, if the qualified mortgages are considered to be
purchased by the REMIC Trust at a discount, some or all of the REMIC Regular
Securities are issued at a discount, and the discount included as a result of a
prepayment on a Mortgage Loan that is used to pay principal on the REMIC Regular
Securities exceeds the REMIC Trust's deduction for unaccrued original issue
discount relating to such REMIC Regular Securities. Taxable income may also be
greater in earlier years because interest expense deductions, expressed as a
percentage of the outstanding principal amount of the REMIC Regular Securities,
may increase over time as the earlier classes of REMIC Regular Securities are
paid, whereas interest income with respect to any given Mortgage Loan expressed
as a percentage of the outstanding principal amount of that Mortgage Loan, will
remain constant over time.
 
     Basis Rules and Distributions.  A Holder of a REMIC Residual Security has
an initial basis in its Security equal to the amount paid for such REMIC
Residual Security. Such basis is increased by amounts included in the income of
the Holder and decreased by distributions and by any net loss taken into account

with respect to such REMIC Residual Security. A distribution on a REMIC Residual
Security to a Holder is not included in gross income to the extent it does not
exceed such Holder's basis in the REMIC Residual Security (adjusted as described
above) and, to the extent it exceeds the adjusted basis of the REMIC Residual
Security, shall be treated as gain from the sale of the REMIC Residual Security.
 
     A Holder of a REMIC Residual Security is not allowed to take into account
any net loss for any calendar quarter to the extent such net loss exceeds such
Holder's adjusted basis in its REMIC Residual Security as of the close of such
calendar quarter (determined without regard to such net loss). Any loss
disallowed by reason of this limitation may be carried forward indefinitely to
future calendar quarters and, subject to the same limitation, may be used only
to offset income from the REMIC Residual Security.
 
     Excess Inclusions.  Any excess inclusions with respect to a REMIC Residual
Security are subject to certain special tax rules. With respect to a Holder of a
REMIC Residual Security, the excess inclusion for any calendar quarter is
defined as the excess (if any) of the daily portions of taxable income over the
sum of the 'daily accruals' for each day during such quarter that such REMIC
Residual Security was held by such Holder. The daily accruals are determined by
allocating to each day during a calendar quarter its ratable portion of the
product of the 'adjusted issue price' of the REMIC Residual Security at the
beginning of the calendar quarter and 120% of the 'federal long-term rate' in
effect on the Settlement Date, based on quarterly compounding, and properly
adjusted for the length of such quarter. For this purpose, the adjusted issue
price of a REMIC Residual Security as of the beginning of any calendar quarter
is equal to the issue price of the REMIC Residual Security, increased by the
amount of daily accruals for all prior quarters and decreased by any
distributions made with respect to such REMIC Residual Security before the
beginning of such quarter. The issue price of a REMIC Residual Security is the
initial offering price to the public (excluding bond houses and brokers) at
which a substantial number of the REMIC Residual Securities was sold. The
federal long-term rate is a blend of current yields on Treasury securities
having a maturity of more than nine years, computed and published monthly by the
IRS.
 
     For Holders of REMIC Residual Securities that are thrift institutions
described in section 593 of the Code, income from a REMIC Residual Security
generally may be offset by losses from other activities. Under the REMIC
Regulations, such an organization is treated as having applied its allowable
deductions for the year first to offset income that is not an excess inclusion
and then to offset that portion of its income that is an excess
 
                                       76

inclusion. For other Holders of REMIC Residual Securities, any excess inclusions
cannot be offset by losses from other activities. For Holders that are subject
to tax only on unrelated business taxable income (as defined in section 511 of
the Code), an excess inclusion of such Holder is treated as unrelated business
taxable income. With respect to variable contracts (within the meaning of
section 817 of the Code), a life insurance company cannot adjust its reserve to
the extent of any excess inclusion, except as provided in regulations. The REMIC
Regulations indicate that if a Holder of a REMIC Residual Security is a member
of an affiliated group filing a consolidated income tax return, the taxable

income of the affiliated group cannot be less than the sum of the excess
inclusions attributable to all residual interests in REMICS held by members of
the affiliated group. For a discussion of the effect of excess inclusions on
certain foreign investors that own REMIC Residual Securities, see '--Foreign
Investors' below.
 
     The REMIC Regulations provide that an organization to which section 593 of
the Code applies and which is the Holder of a REMIC Residual Security may not
use its allowable deductions to offset any excess inclusions with respect to
such Security if such Security does not have 'significant value.' For this
purpose, a REMIC Residual Security has significant value under the REMIC
Regulations if (i) its issue price is at least 2% of the aggregate of the issue
prices of all the REMIC Regular Securities and REMIC Residual Securities in that
REMIC Trust and (ii) its 'anticipated weighted average life' is at least 20% of
the 'anticipated weighted average life' of such REMIC Trust.
 
     In determining whether a REMIC Residual Security has significant value, the
anticipated weighted average life of such Security is based in part on the
Prepayment Assumption, except that all anticipated payments on such Security are
taken into account, regardless of their designation as principal or interest.
The anticipated weighted average life of a REMIC Trust is the weighted average
of the anticipated weighted average lives of the Securities.
 
     The Treasury Department also has the authority to issue regulations that
would treat all taxable income of a REMIC Trust as excess inclusions if the
REMIC Residual Security does not have 'significant value.' Although the Treasury
Department did not exercise this authority in the REMIC Regulations, future
regulations may contain such a rule. If such a rule were adopted, it is unclear
whether the test for significant value that is contained in the REMIC
Regulations and discussed in the two preceding paragraphs would be applicable.
If no such rule is applicable, excess inclusions should be calculated as
discussed above.
 
     In the case of any REMIC Residual Securities that are held by a real estate
investment trust, the aggregate excess inclusions with respect to such REMIC
Residual Securities reduced (but not below zero) by the real estate investment
trust taxable income (within the meaning of section 857(b)(2) of the Code,
excluding any net capital gain) will be allocated among the shareholders of 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 REMIC Residual Security as if held directly by such shareholder.
Similar rules will apply in the case of regulated investment companies, common
trust funds and certain cooperatives that hold a REMIC Residual Security.
 
     Pass-Through of Servicing and Guaranty Fees to Individuals.  A Holder of a
REMIC Residual Security who is an individual will be required to include in
income a share of any servicing and guaranty fees. A deduction for such fees
will be allowed to such Holder only to the extent that such fees, along with
certain of such Holder's other miscellaneous itemized deductions exceed 2% of
such Holder's adjusted gross income. In addition, a Holder of a REMIC Residual
Security may not be able to deduct any portion of such fees in computing such
Holder's alternative minimum tax liability. A Holder's share of such fees will
generally be determined by (i) allocating the amount of such expenses for each
calendar quarter on a pro rata basis to each day in the calendar quarter, and

(ii) allocating the daily amount among the Holders in proportion to their
respective holdings on such day.
 
  Taxes on a REMIC Trust
 
     Prohibited Transactions.  The Code imposes a tax on a REMIC equal to 100%
of the net income derived from 'prohibited transactions.' In general, a
prohibited transaction means the disposition of a qualified mortgage other than
pursuant to certain specified exceptions, the receipt of investment income from
a source other than a Mortgage Loan or certain other permitted investments, the
receipt of compensation for services, or the disposition of an asset purchased
with the payments on the qualified mortgages for temporary investment pending
distribution on the regular and residual interests.
 
                                       77

     Contributions to a REMIC after the Startup Day.  The Code imposes a tax on
a REMIC equal to 100% of the value of any property contributed to the REMIC
after the 'startup day' (generally the same as the Settlement Date). Exceptions
are provided for cash contributions to a REMIC (i) during the three month period
beginning on the startup day, (ii) made to a qualified reserve fund by a Holder
of a residual interest, (iii) in the nature of a guarantee, (iv) made to
facilitate a qualified liquidation or clean-up call, and (v) as otherwise
permitted by Treasury regulations.
 
     Net Income from Foreclosure Property.  The Code imposes a tax on a REMIC
equal to the highest corporate rate on 'net income from foreclosure property.'
The terms 'foreclosure property' (which includes property acquired by deed in
lieu of foreclosure) and 'net income from foreclosure property' are defined by
reference to the rules applicable to real estate investment trusts. Generally,
foreclosure property would be treated as such for a period of two years, with
possible extensions. Net income from foreclosure property generally means gain
from the sale of foreclosure property that is inventory property and gross
income from foreclosure property other than qualifying rents and other
qualifying income for a real estate investment trust.
 
  Sales of REMIC Securities
 
     General.  Except as provided below, if a Regular or REMIC Residual Security
is sold, the seller will recognize gain or loss equal to the difference between
the amount realized in the sale and its adjusted basis in the Security. The
adjusted basis of a REMIC Regular Security generally will equal the cost of such
Security to the seller, increased by any original issue discount or market
discount included in the seller's gross income with respect to such Security and
reduced by distributions on such Security previously received by the seller of
amounts included in the stated redemption price at maturity and by any premium
that has reduced the seller's interest income with respect to such Security. See
'--Discount and Premium.' The adjusted basis of a REMIC Residual Security is
determined as described above under '--Taxation of Holders of REMIC Residual
Securities--Basis Rules and Distributions.' Except as provided in the following
paragraph or under section 582(c) of the Code, any such gain or loss will be
capital gain or loss, provided such Security is held as a 'capital asset'
(generally, property held for investment) within the meaning of section 1221 of
the Code.

 
     Gain from the sale of a REMIC Regular Security that might otherwise be
capital gain will be treated as ordinary income to the extent that such gain
does not exceed the excess, if any, of (i) the amount that would have been
includible in the income of the Holder of a REMIC Regular Security had income
accrued at a rate equal to 110% of the 'applicable federal rate' (generally, an
average of current yields on Treasury securities) as of the date of purchase
over (ii) the amount actually includible in such Holder's income. In addition,
gain recognized on such a sale by a Holder of a REMIC Regular Security who
purchased such a Security at a market discount would also be taxable as ordinary
income in an amount not exceeding the portion of such discount that accrued
during the period such Security was held by such Holder, reduced by any market
discount includible in income under the rules described below under '--Discount
and Premium.'
 
     If a Holder of a REMIC Residual Security sells its REMIC Residual Security
at a loss, the loss will not be recognized if, within six months before or after
the sale of the REMIC Residual Security, such Holder purchases another residual
interest in any REMIC or any interest in a taxable mortgage pool (as defined in
section 7701(i) of the Code) comparable to a residual interest in a REMIC. Such
disallowed loss would be allowed upon the sale of the other residual interest
(or comparable interest) if the rule referred to in the preceding sentence does
not apply to that sale. While this rule may be modified by Treasury regulations,
no such regulations have yet been published.
 
     Transfers of REMIC Residual Securities.  Section 860E(e) of the Code
imposes a substantial tax, payable by the transferor (or, if a transfer is
through a broker, nominee, or other middleman as the transferee's agent, payable
by that agent) upon any transfer of a REMIC Residual Security to a disqualified
organization and upon a pass-through entity (including regulated investment
companies, real estate investment trusts, common trust funds, partnerships,
trusts, estates, certain cooperatives, and nominees) that owns a REMIC Residual
Security if such pass-through entity has a disqualified organization as a
record-holder. For purposes of the preceding sentence, a transfer includes any
transfer of record or beneficial ownership, whether pursuant to a purchase, a
default under a secured lending agreement or otherwise.
 
                                       78

     The term 'disqualified organization' includes the United States, any state
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of the foregoing (other than
certain taxable instrumentalities), any cooperative organization furnishing
electric energy or providing telephone service to persons in rural areas, or any
organization (other than a farmers' cooperative) that is exempt from federal
income tax, unless such organization is subject to the tax on unrelated business
income. Moreover, an entity will not qualify as a REMIC unless there are
reasonable arrangements designed to ensure that (i) residual interests in such
entity are not held by disqualified organizations and (ii) information necessary
for the application of the tax described herein will be made available.
Restrictions on the transfer of a REMIC Residual Security and certain other
provisions that are intended to meet this requirement are described in the
Pooling and Servicing Agreement, and will be discussed more fully in the related
Prospectus Supplement relating to the offering of any REMIC Residual Security.

In addition, a pass-through entity (including a nominee) that holds a REMIC
Residual Security may be subject to additional taxes if a disqualified
organization is a record-holder therein. A transferor of a REMIC Residual
Security (or an agent of a transferee of a REMIC Residual Security, as the case
may be) will be relieved of such tax liability if (i) the transferee furnishes
to the transferor (or the transferee's agent) an affidavit that the transferee
is not a disqualified organization, and (ii) the transferor (or the transferee's
agent) does not have actual knowledge that the affidavit is false at the time of
the transfer. Similarly, no such tax will be imposed on a pass-through entity
for a period with respect to an interest therein owned by a disqualified
organization if (i) the record-holder of such interest furnishes to the
pass-through entity an affidavit that it is not a disqualified organization, and
(ii) during such period, the pass-through entity has no actual knowledge that
the affidavit is false.
 
     Under the REMIC Regulations, a transfer of a 'noneconomic residual
interest' to a U.S. Person (as defined below in '--Foreign Investors--Grantor
Trust Securities and REMIC Regular Securities') will be disregarded for all
federal tax purposes unless no significant purpose of the transfer is to impede
the assessment or collection of tax. A REMIC Residual Security would be treated
as constituting a noneconomic residual interest unless, at the time of the
transfer, (i) the present value of the expected future distributions on the
REMIC Residual Security is no less than the product of the present value of the
'anticipated excess inclusions' with respect to such Security and the highest
corporate 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 applicable REMIC Trust in an amount sufficient to satisfy the liability
for income tax on any 'excess inclusions' at or after the time when such
liability accrues. Anticipated excess inclusions are the excess inclusions that
are anticipated to be allocated to each calendar quarter (or portion thereof)
following the transfer of a REMIC Residual Security, determined as of the date
such Security is transferred and based on events that have occurred as of that
date and on the Prepayment Assumption. See '--Discount and Premium' and
'--Taxation of Holders of REMIC Residual Securities-- Excess Inclusions.'
 
     The REMIC Regulations provide that a significant purpose to impede the
assessment or collection of tax exists if, at the time of the transfer, a
transferor of a REMIC Residual Security has 'improper knowledge' (i.e., either
knew, or should have known, that the transferee would be unwilling or unable to
pay taxes due on its share of the taxable income of the REMIC Trust). A
transferor is presumed not to have improper knowledge if (i) the transferor
conducts, at the time of a transfer, a reasonable investigation of the financial
condition of the transferee and, as a result of the investigation, the
transferor finds that the transferee has historically paid its debts as they
come due and finds no significant evidence to indicate that the transferee will
not continue to pay its debts as they come due in the future; and (ii) the
transferee makes certain representations to the transferor in the affidavit
relating to disqualified organizations discussed above. Transferors of a REMIC
Residual Security should consu lt with their own tax advisors for further
information regarding such transfers.
 
     Reporting and Other Administrative Matters.  For purposes of the
administrative provisions of the Code, each REMIC Trust will be treated as a
partnership and the Holders of REMIC Residual Securities will be treated as

partners. The Trustee will prepare, sign and file federal income tax returns for
each REMIC Trust, which returns are subject to audit by the IRS. Moreover,
within a reasonable time after the end of each calendar year, the Trustee will
furnish to each Holder that received a distribution during such year a statement
setting forth the portions of any such distributions that constitute interest
distributions, original issue discount, and such other information as is
required by Treasury regulations and, with respect to Holders of REMIC Residual
Securities in a REMIC Trust, information necessary to compute the daily portions
of the taxable income (or net loss) of such
 
                                       79

REMIC Trust for each day during such year. The Trustee will also act as the tax
matters partner for each REMIC Trust, either in its capacity as a Holder of a
REMIC Residual Security or in a fiduciary capacity. Each Holder of a REMIC
Residual Security, by the acceptance of its REMIC Residual Security, agrees that
the Trustee will act as its fiduciary in the performance of any duties required
of it in the event that it is the tax matters partner.
 
     Each Holder of a REMIC Residual Security is required to treat items on its
return consistently with the treatment on the return of the REMIC Trust, unless
the Holder either files a statement identifying the inconsistency or establishes
that the inconsistency resulted from incorrect information received from the
REMIC Trust. The IRS may assert a deficiency resulting from a failure to comply
with the consistency requirement without instituting an administrative
proceeding at the REMIC Trust level. Unless otherwise specified in the related
Prospectus Supplement, the Trustee does not intend to register any REMIC Trust
as a tax shelter pursuant to section 6111 of the Code.
 
  Termination
 
     In general, no special tax consequences will apply to a Holder of a REMIC
Regular Security upon the termination of a REMIC Trust by virtue of the final
payment or liquidation of the last Mortgage Loan remaining in the Trust Estate.
If a Holder of a REMIC Residual Security's adjusted basis in its REMIC Residual
Security at the time such termination occurs exceeds the amount of cash
distributed to such Holder in liquidation of its interest, although the matter
is not entirely free from doubt, it would appear that the Holder of the REMIC
Residual Security is entitled to a loss equal to the amount of such excess.
 
DEBT SECURITIES
 
  General
 
     With respect to each series of Debt Securities, Dewey Ballantine, special
tax counsel to the Sponsor, will deliver its opinion to the Sponsor that (unless
otherwise limited in the related Prospectus Supplement) the Securities will be
classified as debt of the Sponsor secured by the related Mortgage Loans.
Consequently, the Debt Securities will not be treated as ownership interests in
the Mortgage Loans or the Trust. Holders will be required to report income
received with respect to the Debt Securities in accordance with their normal
method of accounting. For additional tax consequences relating to Debt
Securities purchased at a discount or with premium, see '--Discount and
Premium,' below.

 
  Special Tax Attributes
 
     As described above, Grantor Trust Securities will possess certain special
tax attributes by virtue of their being ownership interests in the underlying
Mortgage Loans. Similarly, REMIC Securities will possess similar attributes by
virtue of the REMIC provisions of the Code. In general, Debt Securities will not
possess such special tax attributes. Investors to whom such attributes are
important should consult their own tax advisors regarding investment in Debt
Securities.
 
  Sale or Exchange
 
     If a Holder of a Debt Security sells or exchanges such Security, the Holder
will recognize gain or loss equal to the difference, if any, between the amount
received and the Holder's adjusted basis in the Security. The adjusted basis in
the Security generally will equal its initial cost, increased by any original
issue discount or market discount previously included in the seller's gross
income with respect to the Security and reduced by the payments previously
received on the Security, other than payments of qualified stated interest, and
by any amortized premium.
 
     In general (except as described in '--Discount and Premium--Market
Discount,' below), except for certain financial institutions subject to section
582(c) of the Code, any gain or loss on the sale or exchange of a Debt Security
recognized by an investor who holds the Security as a capital asset (within the
meaning of section 1221 of the Code), will be capital gain or loss and will be
long-term or short-term depending on whether the Security has been held for more
than one year.
 
                                       80


DISCOUNT AND PREMIUM
 
     A Security purchased for an amount other than its outstanding principal
amount will be subject to the rules governing original issue discount, market
discount or premium. In addition, all Grantor Trust Strip Securities and certain
Grantor Trust Fractional Interest Securities will be treated as having original
issue discount by virtue of the coupon stripping rules in section 1286 of the
Code. In very general terms, (i) original issue discount is treated as a form of
interest and must be included in a Holder's income as it accrues (regardless of
the Holder's regular method of accounting) using a constant yield method; (ii)
market discount is treated as ordinary income and must be included in a Holder's
income as principal payments are made on the Security (or upon a sale of a
Security); and (iii) if a Holder so elects, premium may be amortized over the
life of the Security and offset against inclusions of interest income. These tax
consequences are discussed in greater detail below.
 
  Original Issue Discount
 
     In general, a Security will be considered to be issued with original issue
discount equal to the excess, if any, of its 'stated redemption price at
maturity' over its 'issue price.' The issue price of a Security is the initial

offering price to the public (excluding bond houses and brokers) at which a
substantial number of the Securities was sold. The issue price also includes any
accrued interest attributable to the period between the beginning of the first
Remittance Period and the Settlement Date. The stated redemption price at
maturity of a Security that has a notional principal amount or receives
principal only or that is or may be an Accrual Security is equal to the sum of
all distributions to be made under such Security. The stated redemption price at
maturity of any other Security is its stated principal amount, plus an amount
equal to the excess (if any) of the interest payable on the first Payment Date
over the interest that accrues for the period from the Settlement Date to the
first Payment Date.
 
     Notwithstanding the general definition, original issue discount will be
treated as zero if such discount is less than 0.25% of the stated redemption
price at maturity multiplied by its weighted average life. The weighted average
life of a Security is apparently computed for this purpose as the sum, for all
distributions included in the stated redemption price at maturity of the amounts
determined by multiplying (i) the number of complete years (rounding down for
partial years) from the Settlement Date until the date on which each such
distribution is expected to be made under the assumption that the Mortgage Loans
prepay at the rate specified in the related Prospectus Supplement (the
'Prepayment Assumption') by (ii) a fraction, the numerator of which is the
amount of such distribution and the denominator of which is the Security's
stated redemption price at maturity. If original issue discount is treated as
zero under this rule, the actual amount of original issue discount must be
allocated to the principal distributions on the Security and, when each such
distribution is received, gain equal to the discount allocated to such
distribution will be recognized.
 
     Section 1272(a)(6) of the Code contains special original issue discount
rules directly applicable to REMIC Securities and Debt Securities and applicable
by analogy to Grantor Trust Securities. Investors in Grantor Trust Securities
should be aware that there can be no assurance that the rules described below
will be applied to such Securities. Under these rules (described in greater
detail below), (i) the amount and rate of accrual of original issue discount on
each series of Securities will be based on (x) the Prepayment Assumption, and
(y) in the case of a Security calling for a variable rate of interest, an
assumption that the value of the index upon which such variable rate is based
remains equal to the value of that rate on the Settlement Date, and (ii)
adjustments will be made in the amount of discount accruing in each taxable year
in which the actual prepayment rate differs from the Prepayment Assumption.
 
     Section 1272(a)(6)(B)(iii) of the Code requires that the prepayment
assumption used to calculate original issue discount be determined in the manner
prescribed in Treasury regulations. To date, no such regulations have been
promulgated. The legislative history of this Code provision indicates that the
assumed prepayment rate must be the rate used by the parties in pricing the
particular transaction. The Sponsor anticipates that the Prepayment Assumption
for each series of Securities will be consistent with this standard. The Sponsor
makes no representation, however, that the Mortgage Loans for a given series
will prepay at the rate reflected in the Prepayment Assumption for that series
or at any other rate. Each investor must make its own decision as to the
appropriate prepayment assumption to be used in deciding whether or not to
purchase any of the Securities.

 
                                       81

     Each Securityholder must include in gross income the sum of the 'daily
portions' of original issue discount on its Security for each day during its
taxable year on which it held such Security. For this purpose, in the case of an
original Holder, the daily portions of original issue discount will be
determined as follows. A calculation will first be made of the portion of the
original issue discount that accrued during each 'accrual period.' The Trustee
will supply, at the time and in the manner required by the IRS, to
Securityholders, brokers and middlemen information with respect to the original
issue discount accruing on the Securities. Unless otherwise disclosed in the
related Prospectus Supplement, the Trustee will report original issue discount
based on accrual periods of one month, each beginning on a payment date (or, in
the case of the first such period, the Settlement Date) and ending on the day
before the next payment date.
 
     Under section 1272(a)(6) of the Code, the portion of original issue
discount treated as accruing for any accrual period will equal the excess, if
any, of (i) the sum of (A) the present values of all the distributions remaining
to be made on the Security, if any, as of the end of the accrual period and (B)
the distribution made on such Security during the accrual period of amounts
included in the stated redemption price at maturity, over (ii) the adjusted
issue price of such Security at the beginning of the accrual period. The present
value of the remaining distributions referred to in the preceding sentence will
be calculated based on (i) the yield to maturity of the Security, calculated as
of the Settlement Date, giving effect to the Prepayment Assumption, (ii) events
(including actual prepayments) that have occurred prior to the end of the
accrual period, (iii) the Prepayment Assumption, and (iv) in the case of a
Security calling for a variable rate of interest, an assumption that the value
of the index upon which such variable rate is based remains the same as its
value on the Settlement Date over the entire life of such Security. The adjusted
issue price of a Security at any time will equal the issue price of such
Security, increased by the aggregate amount of previously accrued original issue
discount with respect to such Security, and reduced by the amount of any
distributions made on such Security as of that time of amounts included in the
stated redemption price at maturity. The original issue discount accruing during
any accrual period will then be allocated ratably to each day during the period
to determine the daily portion of original issue discount.
 
     In the case of Grantor Trust Strip Securities and certain REMIC Securities,
the calculation described in the preceding paragraph may produce a negative
amount of original issue discount for one or more accrual periods. No definitive
guidance has been issued regarding the treatment of such negative amounts. The
legislative history to section 1272(a)(6) indicates that such negative amounts
may be used to offset subsequent positive accruals but may not offset prior
accruals and may not be allowed as a deduction item in a taxable year in which
negative accruals exceed positive accruals. Holders of such Securities should
consult their own tax advisors concerning the treatment of such negative
accruals.
 
     A subsequent purchaser of a Security that purchases such Security at a cost
less than its remaining stated redemption price at maturity also will be
required to include in gross income for each day on which it holds such

Security, the daily portion of original issue discount with respect to such
Security (but reduced, if the cost of such Security to such purchaser exceeds
its adjusted issue price, by an amount equal to the product of (i) such daily
portion and (ii) a constant fraction, the numerator of which is such excess and
the denominator of which is the sum of the daily portions of original issue
discount on such Security for all days on or after the day of purchase).
 
  Market Discount
 
     A Holder that purchases a Security at a market discount, that is, at a
purchase price less than the remaining stated redemption price at maturity of
such Security (or, in the case of a Security with original issue discount, its
adjusted issue price), will be required to allocate each principal distribution
first to accrued market discount on the Security, and recognize ordinary income
to the extent such distribution does not exceed the aggregate amount of accrued
market discount on such Security not previously included in income. With respect
to Securities that have unaccrued original issue discount, such market discount
must be included in income in addition to any original issue discount. A Holder
that incurs or continues indebtedness to acquire a Security at a market discount
may also be required to defer the deduction of all or a portion of the interest
on such indebtedness until the corresponding amount of market discount is
included in income. In general terms, market discount on a Security may be
treated as accruing either (i) under a constant yield method or (ii) in
proportion to remaining accruals of original issue discount, if any, or if none,
in proportion to remaining distributions of interest on the Security, in
 
                                       82

any case taking into account the Prepayment Assumption. The Trustee will make
available, as required by the IRS, to Holders of Securities information
necessary to compute the accrual of market discount.
 
     Notwithstanding the above rules, market discount on a Security will be
considered to be zero if such discount is less than 0.25% of the remaining
stated redemption price at maturity of such Security multiplied by its weighted
average remaining life. Weighted average remaining life presumably would be
calculated in a manner similar to weighted average life, taking into account
payments (including prepayments) prior to the date of acquisition of the
Security by the subsequent purchaser. If market discount on a Security is
treated as zero under this rule, the actual amount of market discount must be
allocated to the remaining principal distributions on the Security and, when
each such distribution is received, gain equal to the discount allocated to such
distribution will be recognized.
 
  Securities Purchased at a Premium
 
     A purchaser of a Security that purchases such Security at a cost greater
than its remaining stated redemption price at maturity will be considered to
have purchased such Security (a 'Premium Security') at a premium. Such a
purchaser need not include in income any remaining original issue discount and
may elect, under section 171(c)(2) of the Code, to treat such premium as
'amortizable bond premium.' If a Holder makes such an election, the amount of
any interest payment that must be included in such Holder's income for each
period ending on a Payment Date will be reduced by the portion of the premium

allocable to such period based on the Premium Security's yield to maturity. The
legislative history of the Tax Reform Act of 1986 states that such premium
amortization should be made under principles analogous to those governing the
accrual of market discount (as discussed above under '--Market Discount'). If
such election is made by the Holder, the election will also apply to all bonds
the interest on which is not excludible from gross income ('fully taxable
bonds') held by the Holder at the beginning of the first taxable year to which
the election applies and to all such fully taxable bonds thereafter acquired by
it, and is irrevocable without the consent of the IRS. If such an election is
not made, (i) such a Holder must include the full amount of each interest
payment in income as it accrues, and (ii) the premium must be allocated to the
principal distributions on the Premium Security and, when each such distribution
is received, a loss equal to the premium allocated to such distribution will be
recognized. Any tax benefit from the premium not previously recognized will be
taken into account in computing gain or loss upon the sale or disposition of the
Premium Security.
 
     Some Securities may provide for only nominal distributions of principal in
comparison to the distributions of interest thereon. It is possible that the IRS
or the Treasury Department may issue guidance excluding such Securities from the
rules generally applicable to debt instruments issued at a premium. In
particular, it is possible that such a Security will be treated as having
original issue discount equal to the excess of the total payments to be received
thereon over its issue price. In such event, section 1272(a)(6) of the Code
would govern the accrual of such original issue discount, but a Holder would
recognize substantially the same income in any given period as would be
recognized if an election were made under section 171(c)(2) of the Code. Unless
and until the Treasury Department or the IRS publishes specific guidance
relating to the tax treatment of such Securities, the Trustee intends to furnish
tax information to Holders of such Securities in accordance with the rules
described in the preceding paragraph.
 
  Special Election
 
     For any Security acquired on or after April 4, 1994, a Holder may elect to
include in gross income all 'interest' that accrues on the Security by using a
constant yield method. For purposes of the election, the term 'interest'
includes stated interest, acquisition discount, original issue discount, de
minimis original issue discount, market discount, de minimis market discount and
unstated interest as adjusted by any amortizable bond premium or acquisition
premium. A Holder should consult its own tax advisor regarding the time and
manner of making and the scope of the election and the implementation of the
constant yield method.
 
BACKUP WITHHOLDING
 
     Distributions of interest and principal, as well as distributions of
proceeds from the sale of Securities, may be subject to the 'backup withholding
tax' under section 3406 of the Code at a rate of 31% if recipients of such
distributions fail to furnish to the payor certain information, including their
taxpayer identification numbers, or
 
                                       83


otherwise fail to establish an exemption from such tax. Any amounts deducted and
withheld from a distribution to a recipient would be allowed as a credit against
such recipient's federal income tax. Furthermore, certain penalties may be
imposed by the IRS on a recipient of distributions that is required to supply
information but that does not do so in the proper manner.
 
FOREIGN INVESTORS
 
  Grantor Trust Securities and REMIC Regular Securities
 
     Distributions made on a Grantor Trust Security or a REMIC Regular Security
to, or on behalf of, a Holder that is not a U.S. Person generally will be exempt
from U.S. federal income and withholding taxes. The term 'U.S. Person' means a
citizen or resident of the United States, a corporation, partnership or other
entity created or organized in or under the laws of the United States or any
political subdivision thereof, or an estate or trust that is subject to U.S.
federal income tax regardless of the source of its income. This exemption is
applicable provided (a) the Holder is not subject to U.S. tax as a result of a
connection to the United States other than ownership of the Security, (b) the
Holder signs a statement under penalties of perjury that certifies that such
Holder is not a U.S. Person, and provides the name and address of such Holder,
and (c) the last U.S. Person in the chain of payment to the Holder receives such
statement from such Holder or a financial institution holding on its behalf and
does not have actual knowledge that such statement is false. Holders should be
aware that the IRS might take the position that this exemption does not apply to
a Holder that also owns 10% or more of the REMIC Residual Securities of any
REMIC trust, or to a Holder that is a 'controlled foreign corporation' described
in section 881(c)(3)(C) of the Code.
 
  REMIC Residual Securities
 
     Amounts distributed to a Holder of a REMIC Residual Security that is a not
a U.S. Person generally will be treated as interest for purposes of applying the
30% (or lower treaty rate) withholding tax on income that is not effectively
connected with a U.S. trade or business. Temporary Treasury Regulations clarify
that amounts not constituting excess inclusions that are distributed on a REMIC
Residual Security to a Holder that is not a U.S. Person generally will be exempt
from U.S. federal income and withholding tax, subject to the same conditions
applicable to distributions on Grantor Trust Securities and REMIC Regular
Securities, as described above, but only to the extent that the obligations
directly underlying the REMIC Trust that issued the REMIC Residual Security
(e.g., Mortgage Loans or regular interests in another REMIC) were issued after
July 18, 1984. In no case will any portion of REMIC income that constitutes an
excess inclusion be entitled to any exemption from the withholding tax or a
reduced treaty rate for withholding. See '--REMIC Securities--Taxation of
Holders of REMIC Residual Securities--Excess Inclusions.'
 
                              ERISA CONSIDERATIONS
 
     The Employee Retirement Income Security Act of 1974, as amended ('ERISA'),
imposes certain fiduciary and prohibited transaction restrictions on employee
pension and welfare benefit plans subject to ERISA ('ERISA Plans'). Section 4975
of the Code imposes essentially the same prohibited transaction restrictions on
tax-qualified retirement plans described in section 401(a) of the Code

('Qualified Retirement Plans') and on Individual Retirement Accounts ('IRAs')
described in section 408 of the Code (collectively, 'Tax-Favored Plans').
 
     Certain employee benefit plans, such as governmental plans (as defined in
Section 3(32) of ERISA), are not subject to the ERISA requirements discussed
herein. Accordingly, assets of such plans may be invested in Securities without
regard to the ERISA considerations described below, subject to the provisions of
applicable federal and state law. Any such plan that is a Qualified Retirement
Plan and exempt from taxation under sections 401(a) and 501(a) of the Code,
however, is subject to the prohibited tran saction rules set forth in section
503 of the Code.
 
     Section 404 of ERISA imposes general fiduciary requirements, including
those of investment prudence and diversification and the requirement that a
Plan's investment be made in accordance with the documents governing the Plan.
In addition, Section 406 of ERISA and section 4975 of the Code prohibit a broad
range of transactions involving assets of ERISA Plans and Tax-Favored Plans
(collectively, 'Plans') and persons
 
                                       84

('Parties in Interest' under ERISA or 'Disqualified Persons' under the Code) who
have certain specified relationships to the Plans, unless a statutory or
administrative exemption is available. Certain Parties in Interest (or
Disqualified Persons) that participate in a prohibited transaction may be
subject to a penalty (or an excise tax) imposed pursuant to Section 502(i) of
ERISA or section 4975 of the Code, unless a statutory or administrative
exemption is available.
 
PLAN ASSET REGULATIONS
 
     A Plan's investment in Securities may cause the Mortgage Loans included in
a Mortgage Pool to be deemed Plan assets. The U.S. Department of Labor (the
'DOL') has promulgated regulations (the 'DOL Regulations') concerning whether or
not a Plan's assets would be deemed to include an interest in the underlying
assets of an entity (such as a Trust Estate), for purposes of applying the
general fiduciary responsibility provisions of ERISA and the prohibited
transaction provisions of ERISA and the Code, when a Plan acquires an 'equity
interest' (such as a Security) in such entity. Because of the factual nature of
certain of the rules set forth in the DOL Regulations, an investing Plan's
assets either may be deemed to include an interest in the assets of a Trust
Estate or may be deemed merely to include its interest in the Securities.
Therefore, Plans should not acquire or hold Securities in reliance upon the
availability of any exception under the DOL Regulations.
 
     The prohibited transaction provisions of Section 406 of ERISA and section
4975 of the Code may apply to a Trust Estate and cause the Sponsor, the Master
Servicer, any Sub-Servicer, the Trustee, the obligor under any Credit
Enhancement mechanism or certain affiliates thereof, to be considered or become
Parties in Interest or Disqualified Persons with respect to an investing Plan.
If so, the acquisition or holding of Securities by or on behalf of the investing
Plan could also give rise to a prohibited trans action under ERISA and the Code,
unless some statutory or administrative exemption is available. Securities
acquired by a Plan would be assets of that Plan. Under the DOL Regulations, the

Trust Estate, including the Mortgage Loans and the other assets held in the
Trust Estate, may also be deemed to be assets of each Plan that acquires
Securities. Special caution should be exercised before the assets of a Plan are
used to acquire a Security in such circumstances, especially if, with respect to
such assets, the Sponsor, the Master Servicer, any Sub-Servicer, the Trustee,
the obligor under any Credit Enhancement mechanism or an affiliate thereof
either (i) has investment discretion with respect to the investment of Plan
assets; or (ii) has authority or responsibility to give (or regularly gives)
investment advice with respect to Plan assets for a fee pursuant to an agreement
or understanding that such advice will serve as a primary basis for investment
decisions with respect to such assets.
 
     Any person who has discretionary authority or control respecting the
management or disposition of Plan assets, and any person who provides investment
advice with respect to such assets for a fee (in the manner described above), is
a fiduciary of the investing Plan. If the Mortgage Loans were to constitute Plan
assets, then any party exercising management or discretionary control regarding
those assets may be deemed to be a Plan 'fiduciary,' and thus subject to the
fiduciary requirements of ERISA and the prohibited transaction provisions of
ERISA and section 4975 of the Code with respect to the investing Plan. In
addition, if the Mortgage Loans were to constitute Plan assets, then the
acquisition or holding of Securities by a Plan, as well as the operation of the
Trust Estate, may constitute or involve a prohibited transaction under ERISA and
the Code.
 
PROHIBITED TRANSACTION CLASS EXEMPTION
 
     The DOL has issued an administrative exemption, Prohibited Transaction
Class Exemption 83-1 ('PTCE 83-1'), which generally exempts from the prohibited
transaction provisions of section 406(a) of ERISA, and from the excise taxes
imposed by sections 4975(a) and (b) of the Code by reason of section
4975(c)(1)(A) through (D) of the Code, certain transactions involving
residential mortgage pool investment trusts relating to the purchase, sale and
holding of securities in the initial issuance of Securities and the servicing
and operation of 'mortgage pools' (as defined below). PTCE 83-1 permits, subject
to certain general and specific conditions, transactions which might otherwise
be prohibited between Plans and Parties in Interest (or Disqualified Persons)
with respect to those Plans, related to the origination, maintenance and
termination of mortgage pools and the acquisition and holding of certain
mortgage pool pass-through Securities representing interests in such mortgage
pools by Plans, whether or not the Plan's assets would be deemed to include an
ownership interest in the mortgage loans in the mortgage pool. PTCE 83-1 is not
available for mortgage pools that include Cooperative Loans and does not provide
an exemption for Subordinate Securities.
 
                                       85

     PTCE 83-1 defines the term 'mortgage pool' as 'an investment pool the
corpus of which (1) is held in trust; and (2) consists solely of (a) interest
bearing obligations secured by either first or second mortgages or deeds of
trust on one- to four-family residential property; (b) property which had
secured obligations and which has been acquired by foreclosure; and (c)
undistributed cash.' The Sponsor expects that each pool of Mortgage Loans (other
than pools including Junior Lien Loans which are not in the second lien

position, Cooperative Loans or Multi-Family Loans) will be a 'mortgage pool'
within the meaning of PTCE 83-1.
 
     PTCE 83-1 defines the term 'mortgage pool pass-through certificate' as a
'certificate representing a beneficial undivided fractional interest in a
mortgage pool and entitling the holder of such certificate to pass-through
payment of principal and interest from the pooled mortgage loans, less any fees
retained by the pool sponsor.' The Sponsor has been advised that, for purposes
of applying PTCE 83-1, the term 'mortgage pool pass-through certificate' would
include (i) Securities representing interests in a Trust Estate consisting of
Mortgage Loans issued in a series consisting of only a single class of
Securities; and (ii) Senior Securities representing interests in a Trust Estate
consisting of Mortgage Loans issued in a series in which there is only one class
of Senior Securities; provided that the Securities described in clauses (i) and
(ii) evidence the beneficial ownership of a specified portion of both future
interest payments and future principal payments with respect to the Mortgage
Loans.
 
     It is not clear whether all types of Securities that may be offered
hereunder would be 'mortgage pass-through certificates' for purposes of applying
PTCE 83-1, including, but not limited to, (a) a class of Securities that
evidences the beneficial ownership of interest payments only or principal
payments only, disproportionate interest and principal payments, or nominal
principal or interest payments, such as the Strip Securities; or (b) Securities
in a series including classes of Securities which differ as to timing,
sequential order, rate or amount of distributions of principal or interest or
both, or as to which 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 Mortgage Pool; or (c) Securities evidencing an interest in a Trust Estate as
to which two or more REMIC elections have been made; or (d) a series including
other types of multiple classes. Accordingly, until further clarification by the
DOL, Plans should not acquire or hold Securities representing interests
described in this paragraph in reliance upon the availability of PTCE 83-1
without first consulting with their counsel regarding the application of PTCE
83-1 to the proposed acquisition and holding of such Securities.
 
     PTCE 83-1 sets forth three general conditions that must be satisfied for
any transaction involving the purchase, sale and holding of 'mortgage pool
pass-through certificates' and the servicing and operation of the 'mortgage
pool' to be eligible for exemption: (1) the pool trustee must not be an
affiliate of the pool sponsor; (2) a system of insurance or other protection for
the pooled mortgage loans and property securing such loans, and for indemnifying
securityholders against reductions in pass-through payments due to property
damage or defaults in loan payments in an amount not less than the greater of 1%
of the aggregate principal balance of all covered pooled mortgages, or the
principal balance of the largest covered mortgage, must be maintained; and (3)
the amount of the payment retained by the pool sponsor together with other funds
inuring to its benefit must be limited to not more than adequate consideration
for forming the mortgage pools plus reasonable compensation for services
provided by the pool sponsor to the mortgage pool. PTCE 83-1 also imposes
additional specific conditions for certain types of transactions involving an
investing Plan and for situations in which the Parties in Interest or
Disqualified Persons are fiduciaries.

 
     The Prospectus Supplement for a series will set forth whether the Trustee
in respect of that series is affiliated with the Sponsor. If the Credit
Enhancement mechanism for a series of Securities constitutes a system of
insurance or other protection within the meaning of PTCE 83-1 and is maintained
in an amount not less than the greater of 1% of the aggregate principal balance
of the Mortgage Loans or the principal balance of the largest Mortgage Loan,
then the Sponsor has been advised that the second general condition referred to
above will be satisfied. The Sponsor will not receive total compensation for
forming and providing services to the Mortgage Pools which will be more than
adequate consideration. Each Plan fiduciary responsible for making the
investment decision whether to acquire or hold Securities must make its own
determination as to whether (i) the Securities constitute 'mortgage pool pass
through certificates' for purposes of applying PTCE 83-1, (ii) the second and
third general conditions will be satisfied, and (iii) the specific conditions,
not discussed herein, of PTCE 83-1 have been satisfied.
 
                                       86

     It should be noted that in promulgating PTCE 83-1 and its predecessor, the
DOL did not have under its consideration interests in pools of the exact nature
described herein. There are other class and individual prohibited transaction
exemptions issued by the DOL that could apply to a Plan's acquisition or holding
of Securities. There can be no assurance that any of those exemptions will apply
with respect to any particular Plan that acquires or holds Securities or, even
if all of the conditions specified therein were satisfied, that the exemption
would apply to all transactions involving the Trust Estate. The related
Prospectus Supplement under 'ERISA Considerations' may contain additional
information regarding the application of PTCE 83-1, or other prohibited
transaction exemptions that may be available, with respect to the series offered
thereby.
 
TAX EXEMPT INVESTORS
 
     A Plan that is exempt from federal income taxation pursuant to Section 501
of the Code (a 'Tax Exempt Investor') nonetheless will be subject to federal
income taxation to the extent that its income is unrelated business taxable
income within the meaning of Section 512 of the Code. All 'excess inclusions' of
a REMIC allocated to a REMIC Residual Security held by a Tax Exempt Investor
will be considered unrelated business taxable income and thus will be subject to
federal income tax. See 'Certain Federal Income Tax Consequences-- REMIC
Securities--Taxation of Holders of REMIC Residual Securities--Excess
Inclusions.'
 
CONSULTATION WITH COUNSEL
 
     Any Plan fiduciary that proposes to cause a Plan to acquire or hold
Securities should consult with its counsel with respect to the potential
applicability of the fiduciary responsibility provisions of ERISA and the
prohibited transaction provisions of ERISA and the Code to the proposed
investment and the availability of PTCE 83-1 or any other prohibited transaction
exemption.
 
                            LEGAL INVESTMENT MATTERS

 
     Certain classes of Securities offered hereby and by the related Prospectus
Supplement will constitute 'mortgage related securities' for purposes of the
Secondary Mortgage Market Enhancement Act of 1984 ('SMMEA') so long as they are
rated in at least the second highest rating category by any Rating Agency, and
as such may be legal investments for persons, trusts, corporations,
partnerships, associations, business trusts and business entities (including
depository institutions, life insurance companies and pension funds) created
pursuant to or existing under the laws of the United States or of any State
whose authorized investments are subject to state regulation to the same extent
that, under applicable law, obligations issued by or guaranteed as to principal
and interest by the United States or any agency or instrumentality thereof
constitute legal investments for such entities. Under SMMEA, if a State enacted
legislation on or prior to October 3, 1991 specifically limiting the legal
investment authority of any such entities with respect to 'mortgage related
securities,' such securities will constitute legal investments for entities
subject to such legislation only to the extent provided therein. Certain States
have enacted legislation which overrides the preemption provisions of SMMEA.
SMMEA provides, however, that in no event will the enactment of any such
legislation affect the validity of any contractual commitment to purchase, hold
or invest in 'mortgage related securities,' or require the sale or other
disposition of such securities, so long as such contractual commitment was made
or such securities acquired prior to the enactment of such legislation.
 
     SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal with 'mortgage
related securities' without limitation as to the percentage of their assets
represented thereby, federal credit unions may invest in such securities, and
national banks may purchase such securities for their own account without regard
to the limitations generally applicable to investment securities set forth in 12
U.S.C. 24 (Seventh), subject in each case to such regulations as the applicable
federal regulatory authority may prescribe.
 
     The Federal Financial Institutions Examination Council has adopted a
supervisory policy statement (the 'Policy Statement'), applicable to all
depository institutions, setting forth guidelines for and significant
restrictions on investments in 'high-risk mortgage securities.' The Policy
Statement has been adopted by the Federal Reserve Board, the Office of the
Comptroller of the Currency, the FDIC and the Office of Thrift Supervision with
an effective date of February 10, 1992. The Policy Statement generally indicates
that a
 
                                       87

mortgage derivative product will be deemed to be high risk if it exhibits
greater price volatility than a standard fixed rate thirty-year mortgage
security. According to the Policy Statement, prior to purchase, a depository
institution will be required to determine whether a mortgage derivative product
that it is considering acquiring is high-risk, and if so, that the proposed
acquisition would reduce the institution's overall interest rate risk. Reliance
on analysis and documentation obtained from a securities dealer or other outside
party without internal analysis by the institution would be unacceptable. There
can be no assurance as to which classes of Securities will be treated as

high-risk under the Policy Statement. In addition, the National Credit Union
Administration has issued regulations governing federal credit union investments
which prohibit investment in certain specified types of securities, which may
include certain classes of Securities. Similar policy statements have been
issued by regulators having jurisdiction over other types of depository
institutions.
 
     There may be other restrictions on the ability of certain investors either
to purchase certain classes of Securities or to purchase any class of Securities
representing more than a specified percentage of the investors' assets. The
Sponsor will make no representations as to the proper characterization of any
class of Securities for legal investment or other purposes, or as to the ability
of particular investors to purchase any class of Securities under applicable
legal investment restrictions. These uncertainties may adversely affect the
liquidity of any class of Securities. Accordingly, all investors whose
investment activities are subject to legal investment laws and regulations,
regulatory capital requirements or review by regulatory authorities should
consult with their own legal advisors in determining whether and to what extent
the Securities of any class constitute legal investments under SMMEA or are
subject to investment, capital or other restrictions, and whether SMMEA has been
overridden in any jurisdiction applicable to such investor.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the related Prospectus Supplement,
substantially all of the net proceeds to be received from the sale of Securities
will be applied by the Sponsor to finance the purchase of, or to repay short-
term loans incurred to finance the purchase of, the Mortgage Loans underlying
the Securities or will be used by the Sponsor for general corporate purposes.
The Sponsor expects that it will make additional sales of securities similar to
the Securities from time to time, but the timing and amount of any such
additional offerings will be dependent upon a number of factors, including the
volume of mortgage loans purchased by the Sponsor, prevailing interest rates,
availability of funds and general market conditions.
 
                            METHODS OF DISTRIBUTION
 
     The Securities offered hereby and by the related Prospectus Supplements
will be offered in series through one or more of the methods described below.
The Prospectus Supplement prepared for each series will describe the method of
offering being utilized for that series and will state the public offering or
purchase price of such series and the net proceeds to the Sponsor from such
sale.
 
     The Sponsor intends that Securities will be offered through the following
methods from time to time and that offerings may be made concurrently through
more than one of these methods or that an offering of a particular series of
Securities may be made through a combination of two or more of these methods.
Such methods are as follows:
 
          1. By negotiated firm commitment or best efforts underwriting and
     public re-offering by underwriters;
 
          2. By placements by the Sponsor with institutional investors through

     dealers; and
 
          3. By direct placements by the Sponsor with institutional investors.
 
     In addition, if specified in the related Prospectus Supplement, a series of
Securities may be offered in whole or in part in exchange for the Mortgage Loans
(and other assets, if applicable) that would comprise the Mortgage Pool in
respect of such Securities.
 
     If underwriters are used in a sale of any Securities (other than in
connection with an underwriting on a best efforts basis), such Securities will
be acquired by the underwriters for their own account and may be resold from
time to time in one or more transactions, including negotiated transactions, at
fixed public offering prices or at
 
                                       88

varying prices to be determined at the time of sale or at the time of commitment
therefor. Such underwriters may be broker-dealers affiliated with the Sponsor
whose identities and relationships to the Sponsor will be as set forth in the
related Prospectus Supplement. The managing underwriter or underwriters with
respect to the offer and sale of a particular series of Securities will be set
forth on the cover of the Prospectus Supplement relating to such series and the
members of the underwriting syndicate, if any, will be named in such Prospectus
Supplement.
 
     In connection with the sale of the Securities, underwriters may receive
compensation from the Sponsor or from purchasers of the Securities in the form
of discounts, concessions or commissions. Underwriters and dealers participating
in the distribution of the Securities may be deemed to be underwriters in
connection with such Securities, and any discounts or commissions received by
them from the Sponsor and any profit on the resale of Securities by them may be
deemed to be underwriting discounts and commissions under the Securities Act of
1933, as amended. The Prospectus Supplement will describe any such compensation
paid by the Sponsor.
 
     It is anticipated that the underwriting agreement pertaining to the sale of
any series of Securities will provide that the obligations of the underwriters
will be subject to certain conditions precedent, that the underwriters will be
obligated to purchase all such Securities if any are purchased (other than in
connection with an underwriting on a best efforts basis) and that, in limited
circumstances, the Sponsor will indemnify the several underwriters and the
underwriters will indemnify the Sponsor against certain civil liabilities,
including liabilities under the Securities Act of 1933, as amended, or will
contribute to payments required to be made in respect thereof.
 
     The Prospectus Supplement with respect to any series offered by placements
through dealers will contain information regarding the nature of such offering
and any agreements to be entered into between the Sponsor and purchasers of
Securities of such series.
 
     The Sponsor anticipates that the Securities offered hereby will be sold
primarily to institutional investors. Purchasers of Securities, including
dealers, may, depending on the facts and circumstances of such purchases, be

deemed to be 'underwriters' within the meaning of the Securities Act of 1933, as
amended, in connection with reoffers and sales by them of Securities. Holders of
Securities should consult with their legal advisors in this regard prior to any
such reoffer or sale.
 
                                 LEGAL MATTERS
 
     Certain legal matters will be passed upon for the Sponsor by Dewey
Ballantine, New York, New York and by the office of the general counsel of the
Sponsor.
 
                             FINANCIAL INFORMATION
 
     The Sponsor has determined that its financial statements are not material
to the offering made hereby. However, any prospective purchaser who desires to
review financial information concerning the Sponsor will be provided by the
Sponsor upon request with a copy of the most recent financial statements of the
Sponsor.
 
     A Prospectus Supplement may contain the financial statements of the related
Credit Enhancer, if any.
 
                             ADDITIONAL INFORMATION
 
     This Prospectus, together with the Prospectus Supplement for each series of
Securities, contains a summary of the material terms of the applicable exhibits
to the Registration Statement and the documents referred to herein and therein.
Copies of such exhibits are on file at the offices of the Securities and
Exchange Commission in Washington, D.C., and may be obtained at rates prescribed
by the Commission upon request to the Commission and may be inspected, without
charge, at the Commission's offices.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Indemnification.  Under the laws which govern the organization of each of
the registrants, each registrant has the power and in some instances may be
required to provide an agent, including an officer or director, who was or is a
party or is threatened to be made a party to certain proceedings, with
indemnification against certain expenses, judgments, fines, settlements and
other amounts under certain circumstances.
 
     Article VII of the By-Laws of Advanta Mortgage Conduit Services, Inc.
provides that the corporation shall indemnify any director, officer, employee or
agent of the corporation against expenses (including legal fees), judgments,
fines and amounts paid in settlement, actually and reasonably incurred by him,
to the fullest extent now, or, if greater, hereafter permitted under applicable
law in connection with any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, brought or
threatened to be brought against him by reason of his performance as a director,
officer, employee or agent of the corporation, its parent or any of its
subsidiaries, or in any other capacity on behalf of the corporation, its parent
or any of its subsidiaries.
 
     Article XI of the By-Laws of Advanta Mortgage Receivables Inc. provides

that the corporation shall indemnify any person (or the estate of any person)
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement, to the fullest extent permitted under applicable law in
connection with any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, brought or threatened
to be brought against him by reason of the fact that he is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another

     The forms of the Underwriting Agreement, incorporated by reference as
Exhibit 1.1 and Exhibit 1.2 to this Registration Statement, provide that Advanta

and each director, officer and controlling person of the underwriter(s) with
respect to certain expenses and liabilities, including liabilities under the
1933 Act or other federal or state regulations or under the common law, which
arise out of or are based on certain material misstatements or omissions in the
Registration Statement. In addition, the Underwriting Agreements provide that
the underwriter(s) will similarly indemnify and reimburse Advanta Mortgage
Conduit Services, Inc. and each director, officer and controlling person of
Advanta Mortgage Conduit Services, Inc. with respect to certain material

     Insurance.  As permitted under the laws which govern the organization of
the Sponsor, the Sponsor has adopted by-laws which permit the board of directors
to purchase and maintain insurance on behalf of the Sponsor's agents, including
its officers and directors, against any liability asserted against them in such
capacity or arising out of such agents' status as such, whether or not the
Sponsor would have the power to indemnify them against such liability under
applicable law. Advanta Mortgage Conduit Services, Inc. has a general liability
policy which insures its agents, including directors and officers, for general
liability exposures.
 
     As permitted by the Employee Retirement Security Act of 1974, Advanta

entrusted with fiduciary responsibilities under certain of its employee welfare
or benefit plans. The maximum coverage provided by this policy is an aggregate
of $5,000,000 per year, subject to a maximum $100,000 deductible amount with
respect to each claim.
 
     As permitted under the laws which govern the organization of the
Transferor, the Transferor has adopted by-laws which permit the board of
directors to purchase and maintain insurance on behalf of any person indemnified
under Article XI of the Transferor's by-laws against any liability which may be
asserted against such person.

of Advanta Mortgage Conduit Services, Inc. and Article Fifth of the Certificate

of Incorporation of Advanta Mortgage Receivables Inc. limit the personal
liability of directors to Advanta Mortgage Conduit Services, Inc. and Advanta

not eliminate or limit a director's liability for (i) breaches of fiduciary duty
of loyalty, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) any unlawful payment
of dividends, stock repurchase or redemption or (iv) any transaction from which
the director derived an improper personal benefit.

ITEM 17.  UNDERTAKINGS.
 
  A.  Undertaking in respect of indemnification
 
     Insofar as indemnification for liabilities arising under the 1933 Act may
be permitted to directors, officers and controlling persons of either registrant
pursuant to the provisions described above in Item 15, or otherwise, each
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by a registrant of expenses
incurred or paid by a director, officer or controlling person of such registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, each registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by such
registrant is against public policy as expressed in the 1933 Act and will be
governed by the final adjudication of such issue.
 
  B.  Undertaking pursuant to Rule 415.
 
     The Registrants hereby undertake:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) to include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) to reflect in the Prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement;
 
             (iii) to include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change of such information in the Registration
        Statement; provided, however, that paragraphs (i) and (ii) do not apply
        if the information required to be included in the post-effective
        amendment is contained in periodic reports filed by the Issuer pursuant
        to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
        that are incorporated by reference in the Registration Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered

     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
                                      II-3

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
  C.  Undertaking pursuant to Rule 430A.
 
     The Registrants hereby undertake:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in Reliance upon Rule 430A and contained in the
     form of prospectus filed by the Registrants pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
                                      II-4
