                       THE TRUST WILL ISSUE:
 
                        Ten classes of senior Class A Certificates, including
                        one interest-only class.
 
                        Two classes of senior principal-only Class P
                        Certificates.
 
                        One class of senior interest-only Class X Certificates.
 
                        One class of senior residual Class A-R Certificates.
 
                        Twelve classes of Class B Certificates, which are
                        subordinate to, and provide credit enhancement for the
                        related senior certificates. Each class of Class B
                        Certificates is also subordinate to each class of
                        related Class B Certificates, if any, with a lower
                        numerical designation.
 
                       THE CERTIFICATES:
 
                        Represent ownership interests in a trust, whose assets
                        are primarily a pool of fixed rate, first lien
                        residential mortgage loans consisting of three loan
                        groups.
 
                        Currently have no trading market.
 
                        Offered pursuant to this prospectus and prospectus
                        supplement are listed under the heading 'Offered
                        Certificates' in the table on page S-3.
 
                       RISKS:
 
                        The yield to investors on each class of certificates
                        will be sensitive to the rate and timing of principal
                        payments on the mortgage loans in the related loan group
                        or loan groups which may vary over time.
 
                        Net interest shortfalls from prepayments on mortgage
                        loans and losses from liquidations of defaulted mortgage
                        loans will adversely affect the yield to investors in
                        the related certificates, and the investors in the
                        related subordinate certificates in particular.

CROSS-COLLATERALIZATION
 
Generally, distributions of principal and interest to the holders of the Senior
Certificates will be based solely on the payments received or advanced on the
Mortgage Loans in the related Loan Group. However, in certain limited
circumstances:
 
 principal and interest collected from the Group I Loans may be used to pay
 principal or interest, or both, to the Group II Senior Certificates; and
 
 principal and interest collected from the Group II Loans may be used to pay
 principal or interest, or both, to the Group I Senior Certificates.
 
We refer you to 'Description of the Certificates -- Cross-Collateralization' in
this prospectus supplement for more detail.
 
PRIORITY OF DISTRIBUTIONS
 
Funds available from payments and other amounts received on the Mortgage Loans
in each Loan Group on any Distribution Date will be distributed to the holders
of the certificates related to that Loan Group in the following order:
 
          (i) to principal of the related Class P Certificates, if any, in the
     manner described in this prospectus supplement under 'Description of the
     Certificates -- Distributions of Principal;'
          (ii) to interest on the interest-bearing related Senior Certificates;
 
          (iii) to principal of the related Senior Certificates (other than the
     related Class P Certificates, if any) entitled to principal;
 
          (iv) to any deferred amounts payable on the related Class P
     Certificates, if any; and
 
          (v) to interest on and principal of each class of Subordinate
     Certificates related to such Loan Group, in order of their numerical class
     designations, beginning with the Class C-B-1 or Class III-B-1 Certificates,
     as applicable.
 
In certain limited circumstances, distributions of principal and interest on the
Group I Senior Certificates and the Group II Senior Certificates may be based on
payments received or advanced with respect to the Group II Loans and Group I
Loans, respectively.
 
We refer you to 'Description of the Certificates -- Priority of Distributions
Among Certificates' and ' -- Cross-Collateralization' in this prospectus
supplement for more detail.
 
INTEREST DISTRIBUTIONS
 
Interest accrues on the interest-bearing Certificates during the calendar month
prior to a Distribution Date.
 
On each Distribution Date, you will be entitled to the following:
 
 interest at the related pass-through rate that accrued during the accrual
 period; and
 
 interest due on a prior Distribution Date that was not paid.
 
Your interest entitlement may be reduced as a result of prepayments on the
Mortgage Loans in the related Loan Group and certain types of losses on the
Mortgage Loans in such Loan Group.
 
The Class P Certificates do not receive interest distributions.
 
We refer you to 'Description of the Certificates -- Distributions of Interest'
in this prospectus supplement for more detail.
 
PRINCIPAL DISTRIBUTIONS
 
Principal distributions are payable on each Distribution Date. Shortfalls in
available funds may result in a class receiving less than what is due. The
calculation of the amount a class is entitled to receive on each Distribution
Date is described in this prospectus supplement under 'Description of the
Certificates -- Distributions of Principal.'

The Notional Amount Certificates do not receive principal distributions.
 
CREDIT ENHANCEMENT
 
Credit enhancement in the form of subordination should reduce delays in
distributions and losses on certain classes of certificates. The subordination
feature will support the classes of certificates in varying degrees.
 
There are two types of subordination in this transaction:
 
1. The Senior Certificates will receive distributions of interest and principal
   prior to distributions of interest and principal to the related Subordinate
   Certificates. Also, on each Distribution Date each class of Subordinate
   Certificates will receive its interest and principal distribution before any
   other related class of Subordinate Certificates with a higher numerical class
   designation; and
 
2. Losses resulting from the liquidation of defaulted Mortgage Loans (other than
   certain excess losses resulting from special hazards, mortgagor fraud or
   mortgagor bankruptcy) will be allocated to the related Subordinate
   Certificates in reverse order of numerical class designation, until the
   respective class balance has been reduced to zero.
 
We refer you to 'Description of the Certificates -- Priority of Distributions
Among Certificates' and ' -- Allocation of Losses' in this prospectus supplement
for more detail.
 
OPTIONAL TERMINATION
 
If the aggregate principal balance of the Mortgage Loans declines below 5% of
the aggregate principal balance of the Mortgage Loans as of April 1, 1999, then
the Depositor may purchase all of the Mortgage Loans and the related properties
in the trust. If the Depositor purchases all of the Mortgage Loans, you will
receive a final distribution and then the trust will be terminated.
 
We refer you to 'Description of the Certificates -- Optional Termination' in
this prospectus supplement for more detail.
 
ADVANCES
 
If a Servicer reasonably believes that cash advances can be recovered from a
delinquent mortgagor or other collections on the Mortgage Loan then such
Servicer will make cash advances to the trust to cover related delinquent
mortgage loan payments. Advances are intended to maintain a regular flow
of scheduled interest and principal payments on the certificates, not to
guarantee or insure against losses.
 
We refer you to 'Servicing of Mortgage Loans -- Advances' in this prospectus
supplement for more detail.
 
FEDERAL INCOME TAX CONSEQUENCES
 
For federal income tax purposes, the trust will comprise two real estate
mortgage investment conduits: the Subsidiary REMIC and the Master REMIC. The
Subsidiary REMIC will hold the Mortgage Loans and will issue several classes of
uncertificated regular interests and a single uncertificated residual interest.
The Master REMIC will hold as assets the regular interests issued by the
Subsidiary REMIC and will issue the several classes of certificates, which,
other than the Class A-R Certificates, will represent regular interests in the
Master REMIC. The Class A-R Certificates will represent ownership of both the
residual interest in the Master REMIC and the residual interest in the
Subsidiary REMIC.
 
We refer you to 'Certain Federal Income Tax Consequences' in this prospectus
supplement and in the prospectus for more detail.
 
ERISA CONSIDERATIONS
 
The fiduciary responsibility provisions of the Employee Retirement Income
Security Act of 1974 (ERISA) and Section 4975 of the Internal Revenue Code of
1986 (the Code) can limit investments by certain pension and other employee
benefit plans. For example, the acquisition of certificates by certain plans may
be considered a 'prohibited transaction' under ERISA; however, certain
exemptions from the prohibited transactions rules could apply. If you are a
fiduciary of a pension or other employee benefit plan, which is subject to ERISA
or Section 4975 of the Code, you should consult with your counsel regarding the
applicability of the provisions of ERISA and the Code before purchasing a
certificate.
 
Subject to the considerations and conditions described under 'ERISA
Considerations' in this prospectus supplement and prospectus, it is expected
that pension or employee benefit plans subject to ERISA or Section 4975 of the
Code may purchase the Senior Certificates other than the Class A-R Certificates.
 
We refer you to 'ERISA Considerations' in this prospectus supplement and in the
prospectus for more detail.

LEGAL INVESTMENT
 
The Senior Certificates and the Class C-B-1 and Class III-B-1 Certificates will
be 'mortgage related securities' for purposes of the Secondary Mortgage Market
Enhancement Act of 1984 (SMMEA), as long as they are rated in one of the two
highest rating categories by at least one nationally recognized statistical
rating organization. The Class C-B-2, Class C-B-3, Class III-B-2 and Class
III-B-3 Certificates will not be rated in one of the two highest rating
categories by a nationally recognized statistical rating organization and
therefore will not be 'mortgage related securities' for purposes of SMMEA.
 
We refer you to 'Legal Investment' in the prospectus for more detail.
 
RATINGS
 
The trust will not issue the Offered Certificates unless they have been assigned
the ratings designated on page S-3.
 
A rating is not a recommendation to buy, sell or hold securities and may be
subject to revision or withdrawal at any time by either rating agency.
 
We refer you to 'Ratings' in this prospectus supplement for more detail.

PREPAYMENTS ON MORTGAGE LOANS MAY ADVERSELY       The rate of principal distributions and yield to maturity on
  AFFECT YIELD                                    your certificates will be directly related to the rate of
                                                  principal payments on the Mortgage Loans in the related Loan
                                                  Group or Loan Groups. Mortgagors may prepay a Mortgage Loan at
                                                  any time. The rate of principal payments on the Mortgage Loans
                                                  will be affected by, among other factors, the following:
                                                    the amortization schedules of the Mortgage Loans;
                                                    the rate of prepayments (including partial prepayments and
                                                    prepayments resulting from refinancing) by mortgagors;
                                                    liquidations of defaulted Mortgage Loans;
                                                    repurchases of Mortgage Loans by the related Seller as a
                                                    result of defective documentation or breaches of
                                                    representations and warranties; and
                                                    the optional purchase by the Depositor of all of the Mortgage
                                                    Loans in connection with the termination of the trust.
                                                  All of the Group I and Group II Loans and a portion of the
                                                  Group III Loans impose a penalty for early full or partial
                                                  prepayments of a mortgage loan if such prepayments are made by
                                                  the mortgagor during a specified period for each such Mortgage
                                                  Loan occurring during the first one to five years after
                                                  origination and the amount of such prepayments in any
                                                  twelve-month period are in excess of 20% of the original
                                                  principal balance of such mortgage loan. Such prepayment
                                                  penalties may discourage borrowers from prepaying their
                                                  mortgage loans during the penalty period and, accordingly,
                                                  affect the rate of prepayment of such mortgage loans even in a
                                                  declining interest rate environment. Any such prepayment
                                                  penalties will be paid to First Nationwide Mortgage Corporation
                                                  or PNC Mortgage Securities Corp., as applicable, and will not,
                                                  in any circumstances, be available for payment of the
                                                  Certificates.
                                                  The rate of principal payments on pools of mortgage loans is
                                                  influenced by a variety of economic, geographic, social and
                                                  other factors. For example, if mortgage rates for similar
                                                  mortgage loans fall below the mortgage rates on the Mortgage
                                                  Loans, the prepayment rate would generally be expected to
                                                  increase. Conversely, if mortgage rates on similar mortgage
                                                  loans rise above the mortgage rates on the Mortgage Loans, the
                                                  prepayment rate would generally be expected to decrease.
                                                  We cannot predict the rate at which mortgagors will repay their
                                                  mortgage loans. Please consider the following:

                                                    Mortgage Loans occur at a slower rate than you expected.
                                                    If you are purchasing a certificate at a premium, your yield
                                                    may be lower than expected if principal payments on the
                                                    Mortgage Loans occur at a faster rate than you expected.
                                                    If you are purchasing a Class III-X Certificate, you should
                                                    consider the risk that a rapid rate of principal payments on
                                                    certain Group III Loans could result in your failure to fully
                                                    recover your initial investment.
                                                    If you are purchasing a Class III-A-6 Certificate, you should
                                                    consider the risk that a rapid rate of principal prepayments
                                                    on the Group III Loans could result in your failure to fully
                                                    recover your initial investment.
                                                    The earlier a payment of principal occurs, the greater the
                                                    impact on your yield. For example, if you purchase a
                                                    certificate at a premium, although the average rate of
                                                    principal payments is consistent with your expectations, if
                                                    the rate of principal payments occurs initially at a rate
                                                    higher than expected, which would adversely impact your
                                                    yield, a subsequent reduction in the rate of principal
                                                    payments will not offset any adverse yield effect.
                                                  We refer you to 'Yield, Prepayment and Maturity Considerations'

RISKS OF HOLDING SUBORDINATE CERTIFICATES         The protections afforded the Senior Certificates in this
                                                  transaction create risks for the related Subordinate
                                                  Certificates. Before purchasing Subordinate Certificates, you
                                                  should consider the following factors that may negatively
                                                  impact your yield:
                                                    Because the Subordinate Certificates receive distributions
                                                    after the related Senior Certificates, there is a greater
                                                    likelihood that one or more classes of Subordinate
                                                    Certificates will not receive the distributions to which they
                                                    are entitled on any Distribution Date.
                                                    If principal payments on the Mortgage Loans are used to make
                                                    interest payments on the related Certificates (because, for
                                                    example, other Mortgage Loans have defaulted), the aggregate
                                                    class balance of the certificates related to such Loan Group
                                                    will exceed the aggregate principal balance of the Mortgage
                                                    Loans in such Loan Group. The class balance of the related
                                                    class of Subordinate Certificates outstanding at that time
                                                    with the highest numerical class designation will be reduced,
                                                    without a corresponding distribution, by the amount of such
                                                    excess.
                                                    If a Servicer determines not to advance a delinquent payment
                                                    because such amount is not recoverable from a mortgagor,
                                                    there will be a shortfall in distributions on the related
                                                    certificates which will initially impact the related
                                                    Subordinate Certificates.

                                                    allocation results in a reduction in a class balance without
                                                    a corresponding distribution of cash to the holder. Also, the
                                                    lower class balance will result in less interest accruing on
                                                    the certificate.
                                                    The earlier in the transaction that a loss on a Mortgage Loan
                                                    occurs, the greater the impact on yield.
                                                    The risks presented in this section are more severe for the
                                                    classes of Subordinate Certificates with higher numerical
                                                    class designations. No class of Subordinate Certificates will
                                                    receive a distribution on any Distribution Date prior to the
                                                    related class or classes of Subordinate Certificates with a
                                                    lower numerical class designation receiving its distribution.
                                                    With limited exceptions, losses on the Mortgage Loans are
                                                    allocated to the related class of Subordinate Certificates
                                                    then outstanding with the highest numerical class
                                                    designation.

LOSSES ON THE GROUP I AND GROUP II LOANS MAY      The applicable coverages for special hazard losses, fraud
REDUCE THE YIELD ON THE SENIOR CERTIFICATES       losses and bankruptcy losses cover the Group I and Group II
UNRELATED TO THAT LOAN GROUP                      Loans. Therefore, if Mortgage Loans in either of these Loan
                                                  Groups suffer a high level of these losses, it will reduce the
                                                  available coverage for certificates related to both the Group I
                                                  and Group II Loans. Moreover, after the available coverage has
                                                  been exhausted, if a Mortgage Loan in either of these Loan
                                                  Groups suffers such a loss, the Senior Certificates related to
                                                  both of these Loan Groups will be allocated a portion of such
                                                  loss.
                                                  Investors in these Senior Certificates should also be aware
                                                  that because the Group C-B Certificates represent interests in
                                                  both the Group I and Group II Loans, the class balance of the
                                                  Group C-B Certificates could be reduced to zero as a result of
                                                  realized losses on the Mortgage Loans in either of these Loan
                                                  Groups. Therefore, the allocation of realized losses on the
                                                  Mortgage Loans in either of these Loan Groups to the Group C-B
                                                  Certificates will reduce the subordination provided by the
                                                  Group C-B Certificates to Group I Senior and Group II Senior
                                                  Certificates, including the Senior Certificates related to a
                                                  Loan Group which did not suffer any losses. This will increase
                                                  the likelihood that

LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO THE  The Mortgage Loans are the sole source of distributions for the
DEPOSITOR, THE SELLERS, THE SERVICERS OR THE      Certificates. The Certificates do not represent an interest in
TRUSTEE                                           or obligation of the Depositor, the Sellers, the Servicers, the
                                                  Trustee or any of their affiliates. Neither the Certificates
                                                  nor the Mortgage Loans will be guaranteed by or insured by any

                                                  Consequently, if payments on the Mortgage Loans are
                                                  insufficient to make all payments required on the Certificates
                                                  you may incur a loss on your investment.
LIMITED LIQUIDITY                                 The Underwriter intends to make a market for the purchase and
                                                  sale of the Offered Certificates after their initial issuance
                                                  but has no obligation to do so. There is currently no secondary
                                                  market for the Offered Certificates. We cannot give you any
                                                  assurance that such a secondary market will develop or, if it
                                                  develops, that it will continue. Consequently, you may not be
                                                  able to sell your Offered Certificates readily or at prices
                                                  that will enable you to realize your desired yield. The market
                                                  values of the Offered Certificates are likely to fluctuate;
                                                  these fluctuations may be significant and could result in
                                                  significant losses to you.
                                                  The secondary markets for mortgage backed securities have
                                                  experienced periods of illiquidity and can be expected to do so
                                                  in the future. Illiquidity can have a severely adverse effect
                                                  on the prices of securities that are especially sensitive to
                                                  prepayment, credit or interest rate risk, or that have been

                                                  in California. If the California residential real estate market
                                                  should experience an overall decline in property values after
                                                  the dates of origination of the Mortgage Loans, the rates of

                                                  Loans may increase, as compared to such rates in a stable or
                                                  improving real estate market. Also, California is more
                                                  susceptible to certain types of uninsurable hazards, such as
                                                  earthquakes, brush fires, floods, mudslides and other natural
                                                  disasters. If any such disaster occurs, the rates of
                                                  delinquency, foreclosure, bankruptcy and loss on the Mortgage
                                                  Loans may increase.

                                                  Certificates in book-entry form may reduce the liquidity of

RISKS ASSOCIATED WITH YEAR 2000 COMPLIANCE        The Servicers are faced with the task of completing their goals
                                                  for compliance in connection with the year 2000 issue. The year
                                                  2000 issue is the result of prior computer programs being
                                                  written using two digits to define the applicable year. Any
                                                  computer programs that have time-sensitive software may
                                                  recognize a date using '00' as the year 1900 rather than the
                                                  year 2000. Any such occurrence could result in a major computer
                                                  system failure or miscalculations. The Servicers are testing
                                                  for potential problems from two-digit programs, and they plan
                                                  to correct or replace their affected computer programs and
                                                  systems on a timely basis (which, in the case of First
                                                  Nationwide, is expected to be the end of the second quarter of
                                                  1999).
                                                  In the event that a Servicer, any subservicer or any of their
                                                  suppliers, customers, brokers or agents do not successfully and
                                                  timely achieve year 2000 compliance, such Servicer's
                                                  performance of its respective obligations under the Agreement
                                                  could be adversely affected. This could result in delays in
                                                  processing payments on the related Mortgage Loans and could
                                                  cause a delay in distributions to you.

of approximately $407,897,647 and the Group II Loans consist of 486 Mortgage
Loans with an aggregate Stated Principal Balance as of the Cut-off Date of
approximately $136,717,984. The Depositor will purchase 850 Mortgage Loans with
an aggregate Stated Principal Balance as of the Cut-off Date of approximately
$305,043,090 (the 'PNC Loans' or 'Group III Loans') directly or indirectly from
PNC Mortgage Securities Corp. ('PNC') pursuant to a Mortgage Loan Purchase
Agreement dated as of April 29, 1999 (the 'PNC Agreement').
 
     Pursuant to a Pooling and Servicing Agreement, dated as of April 1, 1999
(the 'Agreement'), among the Depositor, The First National Bank of Chicago, as
trustee (the 'Trustee'), and First Nationwide and PNC, each as a seller (in such
capacity, a 'Seller') and servicer (in such capacity, a 'Servicer'), the
Depositor will cause the First Nationwide Loans and the PNC Loans (collectively,
the 'Mortgage Loans') and all right, title and interest in and to all other
assets included in the trust fund (the 'Trust Fund'), including all principal
and interest received on or with respect to the Mortgage Loans, exclusive of
principal and interest due on or prior to the Cut-off Date, to be assigned to
the Trustee for the benefit of the holders of the Certificates (the
'Certificateholders').
 
     Under the Agreement, each Seller will make certain representations and
warranties relating to the characteristics of the applicable Mortgage Loans, as
further described in the Prospectus under 'Loan Underwriting Procedures and
Standards -- Representations and Warranties.' Such representations and
warranties relating to the Mortgage Loans will generally be made by the related
Seller as of the Closing Date, or as of such earlier date as specified in the
Agreement. In the event of a breach of any representation or warranty in respect
of a Mortgage Loan that materially and adversely affects the interests of the
Certificateholders in such Mortgage Loan, the related Seller will be obligated,
in accordance with the Agreement, to either cure such breach, or to repurchase
such Mortgage Loan at an amount equal to the sum of (i) the unpaid principal
balance of the Mortgage Loan on the date of such purchase, and (ii) accrued
interest thereon at the applicable Mortgage Rate (net of the applicable
Servicing Fee if the applicable Seller is also the Servicer of the related
Mortgage Loan) from the date through which interest was last paid by the
Mortgagor to the date of such purchase (the 'Purchase Price'), or, in lieu of a
repurchase, to substitute a Replacement Mortgage Loan for such Mortgage Loan;
however, such substitution is permitted only within two years of the Closing
Date and may not be made unless an opinion of counsel is provided to the effect
that such substitution will not disqualify either REMIC or result in a
prohibited transaction under the Code. The Depositor will make no
representations or warranties with respect to the Mortgage Loans and will have
no obligation to repurchase or substitute Mortgage Loans with deficient
documentation or which are otherwise defective. Each Seller is selling the
related Mortgage Loans without recourse and will have no obligation with respect
to the Mortgage Loans in its capacity as Seller other than the cure, repurchase
or substitution obligations described above with respect to the Mortgage Loans
sold by it. The obligations of each Seller, as Servicer, with respect to the
Certificates is limited to its contractual servicing obligations under the
Agreement.
 
     Certain information with respect to the Mortgage Loans to be included in
the mortgage pool (the 'Mortgage Pool') is set forth below. Prior to April 29,
1999 (the 'Closing Date'), Mortgage Loans may be removed from the Mortgage Pool
and other Mortgage Loans may be substituted therefor. The Depositor believes
that the information set forth herein with respect to the Mortgage Pool as
presently constituted is representative of the characteristics of the Mortgage
Pool as it will be constituted at the Closing Date, although certain
characteristics of the Mortgage Loans in the Mortgage Pool may vary. Unless
otherwise indicated, information presented below expressed as a percentage
(other than rates of interest) are approximate percentages based on the Stated
Principal Balances of the Mortgage Loans in the related Loan Groupas of the
Cut-off Date and have been rounded in order to total 100%.

     As of the Cut-off Date, the aggregate Stated Principal Balance of the
Mortgage Loans is expected to be approximately $849,658,723 (the 'Cut-off Date
Pool Principal Balance'). The Mortgage Loans provide for the amortization of the
amount financed over a series of substantially equal monthly payments. All of
the Mortgage Loans provide for payments due on the first day of each month (the
'Due Date'). The Mortgage Loans to be included in the Mortgage Pool were
originated or acquired by the Sellers in the normal course of their business and
substantially in accordance with the underwriting criteria specified herein. At
origination, the Group I Loans had stated terms to maturity which ranged from 20
to 30 years. At origination, the Group II Loans had stated terms to maturity
which ranged from 15 to 30 years. At origination, the Group III Loans had stated
terms to maturity which ranged from 20 to 30 years. Scheduled monthly payments
made by the Mortgagors on the Mortgage Loans ('Scheduled Payments') 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. The majority of the PNC Loans are prepayable at anytime without
penalty. A portion of the PNC Loans and all of the First Nationwide Loans impose
certain penalties for early prepayments (except for prepayments due to the sale
of the Mortgaged Property) (each, a 'Prepayment Penalty Loan'). During a
specified period for each Prepayment Penalty Loan lasting anywhere from one to
five years after the origination thereof (the 'Penalty Period'), the Mortgagor
may not prepay more than 20% of the original principal amount of such Mortgage
Loan in any twelve month period without incurring a penalty. With respect to
each Prepayment Penalty Loan, the penalty is equal to the lesser of (i) six
months' interest on such excess and (ii) the amount authorized by applicable
law. No penalty will be imposed after the Penalty Period.
 
     Each Group I Loan has a first payment date on or after March 1, 1998. Each
Group II Loan has a first payment date on or after June 1, 1998. Each Group III
Loan has a first payment date on or after January 1, 1996.
 
     The latest stated maturity date of any Group I Loan is April 1, 2029, and
the earliest stated maturity date of any Group I Loan is April 1, 2019. The
latest stated maturity date of any Group II Loan is April 1, 2029, and the
earliest stated maturity date of any Group II Loan is April 1, 2014. The latest
stated maturity date of any Group III Loan is June 1, 2029, and the earliest
stated maturity date of any Group III Loan is November 1, 2018.
 
     As of the Cut-off Date, no Mortgage Loan will be delinquent more than 30
days.
 
     No Mortgage Loan is subject to a buydown agreement. No Mortgage Loan
provides for deferred interest or negative amortization.
 
     Except for 125 Group III Loans, representing approximately 12.17% of the
aggregate Stated Principal Balance of the Group III Loans, as of the Cut-off
Date, all of the Mortgage Loans as of the Cut-off Date had a Loan-to-Value Ratio
at origination of 80% or less. Except for 27 Mortgage Loans, representing
approximately 2.60% of the Cut-off Date Pool Principal Balance, each Mortgage
Loan with a Loan-to-Value Ratio at origination of greater than 80% will be
covered by a primary mortgage guaranty insurance policy issued by a mortgage
insurance company acceptable to the Federal National Mortgage Association
('FNMA'), the Federal Home Loan Mortgage Corporation ('FHLMC') or any nationally
recognized statistical rating organization or the Group PMI Policy (as defined
below). Each primary mortgage guaranty insurance policy provides coverage of a
portion of the original principal balance of the related Mortgage Loan equal to
the product of the original principal balance thereof and a fraction, the
numerator of which is the excess of the original principal balance of the
related Mortgage Loan over 75% of the lesser of the appraised value and selling
price of the related Mortgaged Property and the denominator of which is the
original principal balance of the related Mortgage Loan, plus accrued interest
thereon and related foreclosure expenses. No such primary mortgage guaranty
insurance policy will be required with respect to any such Mortgage Loan after
the date on which the related Loan-to-Value Ratio is 80% or less or, based on a
new appraisal, the principal balance of such Mortgage Loan represents 80% or
less of the new appraised value. See ' -- Underwriting Standards' herein.
 
     As of the Cut-off Date, approximately 2.83% of the Group III Loans are
covered by primary mortgage guaranty insurance policies or the Group PMI Policy,
the premiums of which are paid by the applicable subservicers out of the
Servicing Fees for the Group III Loans.
 
                                      S-14

<PAGE>
     As of the Cut-Off Date, approximately 23.26% of the Group III Loans have
Loan-to-Value Ratios in excess of 80% but not in excess of 95%, and are not
covered by traditional primary mortgage guaranty insurance policies. Instead,
these Mortgage Loans are covered by a mortgage pool insurance policy (the 'Group
PMI Policy') issued by Commonwealth Mortgage Assurance Company. The Group PMI
Policy provides coverage substantially similar to traditional primary mortgage
guaranty insurance policies. Each Group III Loan covered by the Group PMI Policy
(each, a 'Group PMI Loan') with an initial Loan-to-Value Ratio of at least
80.01% up to and including 89.99% is covered by the Group PMI Policy in an
amount equal to 22% of the appraised value of the related Mortgage Property, in
each case, at the time of the origination of such Group PMI Loan. Each Group PMI
Loan with an initial Loan-to-Value Ratio of at least 90.00% up to and including
95.00% is covered by the Group PMI Policy in an amount equal to 30% of the
appraised value of the related Mortgaged Property, in each case, at the time of
the origination of such Group PMI Loan. The Group PMI Policy does not cover
Mortgage Loans with an initial Loan-to-Value Ratio in excess of 95.00%.
 
     The Group PMI Policy covers losses in an aggregate amount of 10% of the
initial principal balance of the mortgage loans covered under the Group PMI
Policy (up to a maximum aggregate principal balance of $2,000,000,000). Since
the Group PMI Policy insures mortgage loans other than the Group PMI Loans
(including mortgage loans not included in the Mortgage Pool) losses on such
other mortgage loans may deplete the coverage available under the Group PMI
Policy for losses incurred in connection with the Group PMI Loans. The premiums
payable to Commonwealth Mortgage Assurance Company for coverage of each Group
PMI Loan under the Group PMI Policy will be paid by the applicable subservicers
out of the Servicing Fees for such Group PMI Loans.
 
     The 'Loan-to-Value Ratio' of a Mortgage Loan at any given time is a
fraction, expressed as a percentage, the numerator of which is the principal
balance of the related Mortgage Loan at the date of determination and the
denominator of which is (a) in the case of a purchase, the lesser of the selling
price of the Mortgaged Property and its appraised value determined in an
appraisal obtained by the originator at origination of such Mortgage Loan, or
(b) in the case of a refinance, the appraised value of the Mortgaged Property at
the time of such refinance. No assurance can be given that the value of any
Mortgaged Property has remained or will remain at the level that existed on the
appraisal or sales date. If residential real estate values generally or in a
particular geographic area decline, the Loan-to-Value Ratios might not be a
reliable indicator of the rates of delinquencies, foreclosures and losses that
could occur with respect to such Mortgage Loans.
 
     The following information sets forth in tabular format certain information,
as of the Cut-off Date, as to the Mortgage Loans in each Loan Group. Other than
with respect to rates of interest, percentages (approximate) are stated by
Stated Principal Balance of the Mortgage Loans in the related Loan Group as of
the Cut-off Date and have been rounded in order to total 100%.

UNDERWRITING STANDARDS
 
     The Mortgage Loans have either been originated by a Seller or purchased by
a Seller from various banks, savings and loan associations, mortgage bankers
(which may or may not be affiliated with a Seller) and other mortgage loan
originators, and were originated generally in accordance with the underwriting
criteria described herein.
 
     All of the Mortgage Loans are 'conventional non-conforming mortgage loans'
(i.e., loans which are not insured by the Federal Housing Authority or partially
guaranteed by the Veterans Administration or which do not qualify for sale to
FNMA or FHLMC). The underwriting standards applicable to the Mortgage Loans
typically differ from, and are generally less stringent than, the underwriting
standards established by FNMA or FHLMC primarily with respect to original
principal balances, loan-to-value ratios, borrower income, borrower credit
history, borrower employment history, required documentation, interest rates,
borrower occupancy of the mortgaged property and/or property types. To the
extent the programs reflect underwriting standards different from these of FNMA
and FHLMC, the performance of the mortgage loans thereunder may reflect higher
delinquency rates and/or credit losses. In addition, certain exceptions to the
underwriting standards described herein are made in the event that compensating
factors are demonstrated by a prospective borrower. Neither the Depositor nor
any affiliate has re-underwritten any Mortgage Loan. In addition, neither First
Nationwide nor any affiliate has re-underwritten any First Nationwide Loan that
was purchased by First Nationwide rather than originated by First Nationwide. In
addition, neither PNC nor any PNC affiliate has re-underwritten any PNC Loan
that was purchased by PNC rather than originated by PNC or a PNC affiliate.
 
     Generally, each Mortgagor will have been required to complete an
application designed to provide to the original lender pertinent credit
information concerning the Mortgagor. As part of the description of the
Mortgagor's financial condition, such Mortgagor will have furnished information
(which may be supplied solely in such application) with respect to its assets,
liabilities, income (except as described below), credit history, employment
history and personal information, and furnished an authorization to apply for a
credit report which summarizes the Mortgagor's credit history with local
merchants and lenders and any record of bankruptcy. The Mortgagor may also have
been required to authorize verifications of deposits at financial institutions
where the Mortgagor had demand or savings accounts. In the case of investment
properties and two- to four-unit dwellings, income derived from the Mortgaged
Property may have been considered for underwriting purposes, in addition to the
income of the Mortgagor from other sources. With respect to Mortgaged Property
consisting of vacation or second homes, no income derived from the property
generally will have been considered for underwriting purposes. In the case of
certain Mortgagors with acceptable payment histories, no income will be required
to be stated (or verified) in connection with the loan application.
 
     Based on the data provided in the application and certain verification (if
required), a determination is made by the original lender that the Mortgagor's
monthly income (if required to be stated) will be sufficient to enable the
Mortgagor to meet its monthly obligations on the Mortgage Loan and other
expenses related to the Mortgaged Property (such as property taxes, utility
costs, standard hazard insurance and other fixed obligations other than housing
expenses). Generally, scheduled payments on a Mortgage Loan during the first
year of its term plus taxes and insurance and all scheduled payments on
obligations that extend beyond ten months (including those mentioned above and
other fixed obligations) equal no more than a specified percentage of the
prospective Mortgagor's gross income. The percentage applied varies on a case by
case basis depending on a number of underwriting criteria, including the
Loan-to-Value Ratio of the Mortgage Loan. The originator may also consider the
amount of liquid assets available to the Mortgagor after origination.
 
     Certain of the Mortgage Loans have been originated under 'reduced
documentation,' 'no stated income,' 'no ratio' or 'no documentation' programs
which require less documentation and verification than do traditional 'full
documentation' programs. Generally, under a 'reduced documentation' program, no
verification of a mortgagor's stated income is undertaken by the originator.
Under a 'no stated income' or 'no ratio' program, certain borrowers with
acceptable payment histories will not be required to provide any information
regarding income and no other investigation regarding the borrower's income will
be undertaken. Under a 'no documentation' program, no verification of a
mortgagor's income or assets is undertaken by the originator. The underwriting
for such Mortgage Loans may be based primarily or entirely on an appraisal of
the Mortgaged Property and the Loan-to-Value Ratio at origination.
 
     The adequacy of the Mortgaged Property as security for repayment of the
related Mortgage Loan will generally have been determined by an appraisal in
accordance with pre-established appraisal procedure guidelines for appraisals
established by or acceptable to the originator. All appraisals conform to the
Uniform
 
                                      S-20
 

<PAGE>

<PAGE>
Standards of Professional Appraisal Practice adopted by the Appraisal Standards
Board of the Appraisal Foundation and must be on forms acceptable to FNMA and/or
FHLMC. Appraisers may be staff appraisers employed by the originator or
independent appraisers selected in accordance with pre-established appraisal
procedure guidelines established by or acceptable to the originator. The
appraisal procedure guidelines generally will have required the appraiser or an
agent on its behalf to personally inspect the property and to verify whether the
property was in good condition and that construction, if new, had been
substantially completed. The appraisal generally will have been based upon a
market data analysis of recent sales of comparable properties and, when deemed
applicable, an analysis based on income generated from the property or a
replacement cost analysis based on the current cost of constructing or
purchasing a similar property.
 
ASSIGNMENT OF THE MORTGAGE LOANS
 
     Pursuant to the Agreement, the Depositor on the Closing Date will sell,
transfer, assign, set over and otherwise convey without recourse to the Trustee
in trust for the benefit of the Certificateholders all right, title and interest
of the Depositor in and to each Mortgage Loan and all right, title and interest
in and to all other assets included in the Trust Fund, including all principal
and interest received on or with respect to such Mortgage Loans, exclusive of
principal and interest due on or prior to the Cut-off Date.
 
     In connection with such transfer and assignment, the Depositor will deliver
or cause to be delivered to the Trustee, or a custodian for the Trustee, among
other things, the original promissory note (the 'Mortgage Note') (and any
modification or amendment thereto) endorsed in blank without recourse, except
that the Depositor may deliver or cause to be delivered a lost note affidavit in
lieu of any original Mortgage Note that has been lost, the original instrument
creating a first lien on the related Mortgaged Property (the 'Mortgage') with
evidence of recording indicated thereon, an assignment in recordable form of the
Mortgage, the title policy with respect to the related Mortgaged Property and,
if applicable, all recorded intervening assignments of the Mortgage and any
riders or modifications to such Mortgage Note and Mortgage (except for any such
document not returned from the public recording office, which will be delivered
to the Trustee as soon as the same is available to the Depositor) (collectively,
the 'Mortgage File'). Assignments of the Mortgages to the Trustee (or its
nominee) will be recorded in the appropriate public office for real property
records, except in states where, in the opinion of counsel, such recording is
not required to protect the Trustee's interest in the Mortgage Loan against the
claim of any subsequent transferee or any successor to or creditor of the
Depositor or the related Seller.
 
     The Trustee will review each Mortgage File within 90 days of the Closing
Date (or promptly after the Trustee's receipt of any document permitted to be
delivered after the Closing Date) and if any document in a Mortgage File is
found to be missing or defective in a material respect and the applicable Seller
does not cure such defect within 90 days of notice thereof from the Trustee (or
within such longer period not to exceed 720 days after the Closing Date in the
case of missing documents not returned from the public recording office), such
Seller will be obligated to repurchase the related Mortgage Loan from the Trust
Fund. Rather than repurchase the Mortgage Loan as provided above, such Seller
may remove such Mortgage Loan (a 'Deleted Mortgage Loan') from the Trust Fund
and substitute in its place another mortgage loan (a 'Replacement Mortgage
Loan'); however, such substitution is permitted only within two years of the
Closing Date and may not be made unless an opinion of counsel is provided to the
effect that such substitution will not disqualify either REMIC or result in a
prohibited transaction under the Code. Any Replacement Mortgage Loan generally
will, on the date of substitution, among other characteristics set forth in the
Agreement, (i) have a principal balance, after deduction of all Scheduled
Payments due in the month of substitution, not in excess of, and not more than
10% less than, the Stated Principal Balance of the Deleted Mortgage Loan (the
amount of any shortfall to be deposited by the related Seller and held for
distribution to the Certificateholders on the related Distribution Date (a
'Substitution Adjustment Amount')), (ii) have a Mortgage Rate not lower than,
and not more than 1% per annum higher than, that of the Deleted Mortgage Loan,
(iii) have a Loan-to-Value Ratio not higher than that of the Deleted Mortgage
Loan, (iv) have a remaining term to maturity not greater than, and not more than
one year less than, that of the Deleted Mortgage Loan, and (v) comply with all
of the representations and warranties set forth in the Agreement as of the date
of substitution. This cure, repurchase or substitution obligation constitutes
the sole remedy available to Certificateholders or the Trustee for omission of,
or a material defect in, a Mortgage Loan document.

FIRST NATIONWIDE
 
     First Nationwide, a Delaware corporation and a wholly-owned subsidiary of
California Federal Bank, FSB, is a mortgage company engaged in the business of
originating and servicing a variety of loan products including non-conforming
residential mortgage loans (also known as 'jumbo' mortgage loans). First
Nationwide originates mortgage loans through various channels, including
wholesale brokers, correspondents, California Federal Bank, FSB, branches and
its own regional offices. First Nationwide's executive offices are located at
5280 Corporate Drive, Frederick, Maryland 21701.
 
FIRST NATIONWIDE'S DELINQUENCY EXPERIENCE
 
     As of December 31, 1998, First Nationwide's total loan servicing portfolio
contained 956,789 loans with an aggregate outstanding principal balance of
approximately $86.3 billion. The loans contained in First Nationwide's servicing
portfolio include fixed and adjustable rate loans, first and second lien loans
and one- to four-family loans and therefore may differ significantly from the
First Nationwide Loans. There can be no assurance, and no representation is
made, that the delinquency experience with respect to the First Nationwide Loans
will be similar to that reflected in the table below, nor is any representation
made as to the rate at which losses may be experienced on liquidation of
defaulted First Nationwide Loans.
 
     The following table sets forth certain information regarding the
delinquency experience of First Nationwide with respect to all mortgage loans
serviced by it. The indicated periods of delinquency are based on the number of
days past due on a contractual basis.

     The above delinquency statistics represent the recent experience of First
Nationwide. There can be no assurance, however, that the delinquency experience
on the First Nationwide Loans will be comparable. In addition, the foregoing
statistics include mortgage loans with a variety of payment and other
characteristics that may not correspond to those of the First Nationwide Loans.
Further, the First Nationwide Loans were not chosen from First Nationwide's
portfolio on the basis of any methodology which could or would make them
representative of the total pool of mortgage loans in First Nationwide's
portfolio. The actual loss and delinquency experience on the First Nationwide
Loans will depend on, among other things, national or local economic conditions,
declines in real estate values, the value of the real estate securing such First
Nationwide Loans and the ability of the mortgagors to make required payments.
 
PNC
 
     PNC, a Delaware corporation, is a wholly-owned indirect subsidiary of PNC
Bank Corp., a bank holding company. PNC was organized for the purpose of
providing mortgage lending institutions, including affiliated institutions, with
greater financing and lending flexibility by purchasing mortgage loans from such
institutions and issuing mortgage-backed securities. PNC's principal executive
offices are located at 75 North Fairway Drive, Vernon Hills, Illinois 60061, and
its telephone number is (847) 549-6500.

PNC'S DELINQUENCY AND FORECLOSURE EXPERIENCE
 
     The following table sets forth certain information as reported to PNC by
its various servicers, concerning recent delinquency and foreclosure experience
on mortgage loans included in various mortgage pools underlying all series of
PNC's mortgage pass-through certificates with respect to which one or more
classes of certificates were publicly offered. The delinquency and foreclosure
experience set forth in the following table may not be representative of the
results that will be experienced with respect to the PNC Loans included in the
Trust Fund or any portion thereof.
 
     There can be no assurance that the delinquency and foreclosure experience
set forth in the following table (which includes mortgage loans with various
terms to stated maturity, and includes loans having a variety of payment
characteristics such as balloon loans and buydown loans) will be representative
of the results that may be experienced with respect to the PNC Loans included in
the Trust Fund. Delinquencies and foreclosures generally are expected to occur
more frequently after the first full year of the life of a mortgage loan.
Accordingly, because a large number of the mortgage loans underlying PNC's
mortgage pass-through certificates have been recently originated, the current
level of delinquencies and foreclosures may not be representative of the levels
which may be experienced over the lives of such mortgage loans.

PNC'S YEAR 2000 READINESS DISCLOSURE
 
     PNC has been working since 1997 to prepare its computer systems and
applications to meet the year 2000 challenge. This process involves reviewing,
modifying and replacing existing hardware, software and embedded chip technology
systems, as necessary. PNC is also assessing the year 2000 preparedness of third
parties such as vendors, customers and others.
 
     As of December 31, 1998, approximately 99% of PNC's MIS-supported
mainframe, mid-range and PC client-server systems had been tested and returned
to production as year 2000 ready. Approximately 99% of PNC's non-PC related
hardware and systems software had also been tested and determined to be year
2000 ready as of that date. At year-end 1998, PNC had also substantially
completed an organization-wide assessment of year 2000 issues relating to its
mission critical systems which utilize embedded chip technologies. No
significant problems have been identified to date with respect to embedded chip
technology systems.
 
     PNC has substantially completed its assessment of the year 2000
preparedness of its identified mission critical service providers. PNC has not
to date identified any material problems associated with its mission critical
service providers.
 
                                      S-23
 

<PAGE>

<PAGE>
     During the spring of 1999, PNC plans to conduct fully integrated testing of
its systems and applications to determine whether its mission critical
application systems will perform in coordination with one another. The mission
critical applications systems will be tested on year 2000-ready hardware and
software using dates both in 1999 and 2000. PNC also intends to conduct testing
during 1999 with those mission critical vendors that provide systems-related
services.
 
     The estimated total cost to become year 2000 compliant, which is being
expensed as incurred by PNC jointly with its affiliate PNC Mortgage Corp. of
America, is approximately $1.41 million. Through December 31, 1998, PNC and its
affiliate had expensed approximately $1.13 million related to the year 2000
effort. Expenses incurred for year 2000 readiness efforts comprised less than
5.5% of the total technology-related costs for PNC and its affiliate in 1998 and
are not expected to exceed 1.6% of technology-related expenses in 1999 for PNC
and its affiliate. No significant outlays have been made to replace existing
systems solely for year 2000 compliance reasons. The costs and the timetable in
which PNC plans to complete its year 2000 readiness activities are based on
management's best estimates, which were derived using numerous assumptions of
future events including the continued availability of certain resources, third
party preparedness and other factors. PNC can make no guarantee that these
estimates will be achieved, and actual results could differ from such plans.
 
     Contingency plans have been completed for those systems that were not
tested and returned to production by October 31, 1998, and for those critical
service providers who either were not expected to be year 2000 ready by March
31, 1999, or did not respond to requests for year 2000 readiness information.
Contingency plans are being developed for mission critical end-user computing
applications that were not tested by December 15, 1998. In addition, business
continuity plans were completed by February 28, 1999. PNC will continue to
review all contingency plans during 1999 and modify them when necessary or
appropriate. Certain critical service provider and systems contingency plans
will be tested during 1999.
 
     It is not possible to predict with certainty all of the adverse effects
that could result from a failure of PNC or of third parties to become fully year
2000 compliant or whether such effects could have a material impact on PNC.
However, if PNC were to fail to correct internal year 2000 problems, or if one
or more of its third party providers are unable due to year 2000 issues to
provide services required by PNC, a disruption of operations, resulting in
increased operating costs and other adverse effects, could result. Such
disruptions could include a temporary inability to process transactions and
delays in providing services.
 
     This section entitled ' -- PNC's Year 2000 Readiness Disclosure' contains
'forward-looking statements' within the meaning of Section 27A of the Securities
Act. Generally, all statements in this section that are not statements of
historical fact are forward-looking statements. Forward-looking statements made
in this section are subject to certain risks and uncertainties. Important
factors that could cause results to differ materially from such forward-looking
statements include, among other things, the ability of PNC to successfully
identify components that may pose year 2000 problems, the nature and amount of
programming required to fix the affected components, the costs of labor and
consultants related to such efforts, the continued availability of resources
(both personnel and technology) and the ability of PNC's third-party suppliers
and service providers to successfully address their year 2000 issues.
 
                          SERVICING OF MORTGAGE LOANS
 
GENERAL
 
     Pursuant to the Agreement, First Nationwide will act as Servicer of the
First Nationwide Loans and PNC will act as Servicer of the PNC Loans. Each
Servicer will be responsible for servicing the Mortgage Loans serviced by it in
accordance with the terms of the Agreement, employing that degree of skill and
care which it employs in servicing mortgage loans comparable to such Mortgage
Loans serviced by it for itself or others. Neither Servicer will have any
servicing obligations with respect to the Mortgage Loans not serviced by it.
 
     Each Servicer will make reasonable efforts to collect or cause to be
collected all payments called for under the terms and provisions of the Mortgage
Loans serviced by it and, to the extent such procedures are consistent with the
Agreement, will follow collection procedures as are followed with respect to the
mortgage loans comparable to such Mortgage Loans in the local areas where each
Mortgaged Property is located. Pursuant to the Agreement, each Servicer will
establish and maintain, or cause to be established and maintained, one or more
accounts (each, a 'Collection Account'), into which deposits will be made on a
daily basis of payments
 
                                      S-24
 

<PAGE>

<PAGE>
and collections on the Mortgage Loans serviced by it (net of the related
servicing compensation). If permitted by the Agreement, a Collection Account may
be a commingled account with other similar accounts maintained by the related
Servicer. Funds credited to a Collection Account may be invested for the benefit
and at the risk of the related Servicer in Permitted Investments, as defined in
the Agreement, that are scheduled to mature on or prior to the business day
preceding the next Distribution Date.
 
     The Agreement prohibits the resignation of a Servicer, except upon (a)
appointment of a successor servicer and receipt by the Trustee of a letter from
each Rating Agency that such a resignation and appointment will not result in a
downgrading of the rating of any of the Certificates, or (b) a determination
that its duties thereunder are no longer permitted under applicable law. No such
resignation will be effective until a successor servicer has assumed such
servicing obligations in the manner provided in the Agreement.
 
     In accordance with the Agreement, each Servicer may contract with
subservicers to perform some or all of its servicing duties. Notwithstanding any
such servicing arrangement, each Servicer will remain liable for its servicing
duties and obligations under the Agreement as if such Servicer alone were
servicing the Mortgage Loans.
 
     All references to 'Master Servicer' in the Prospectus should be read to be
references to the Servicers described in this Prospectus Supplement.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Expense Fees with respect to each of the respective Loan Groups are
payable out of the interest payments on each Mortgage Loan in the related Loan
Group. The Expense Fees will vary from Mortgage Loan to Mortgage Loan within a
Loan Group. The rate at which the Expense Fees accrue (the 'Expense Fee Rate')
is expected to range from 0.250% to 0.8750% per annum with respect to the Group
I Loans, from 0.250% to 1.500% per annum with respect to the Group II Loans and
from 0.300% to 1.580% per annum with respect to the Group III Loans, in each
case of the principal balance of the related Mortgage Loan. As of the Cut-off
Date, the weighted average Expense Fee Rate is expected to equal approximately
0.4580% per annum with respect to the Group I Loans, 0.6549% per annum with
respect to the Group II Loans and 0.7963% per annum with respect to the Group
III Loans. The Expense Fees consist of (a) servicing compensation payable to
each Servicer in respect of its servicing activities concerning the Mortgage
Loans serviced by it (each, a 'Servicing Fee'), (b) fees payable to the Trustee
in respect of its activities as trustee under the Agreement and (c) with respect
to certain of the First Nationwide Loans and PNC Loans, the excess servicing fee
payable to First Nationwide and PNC on the First Nationwide Loans and the PNC
Loans, respectively (the 'Excess Servicing Fee'). The weighted average Servicing
Fee payable to First Nationwide will be approximately 0.2483% per annum of the
principal balance of each First Nationwide Loan and the weighted average
Servicing Fee payable to PNC will be approximately 0.2655% per annum of the
Stated Principal Balance of each PNC Loan. The Excess Servicing Fee payable to
First Nationwide will range from 0.000% to 1.240% per annum, of the principal
balance of each First Nationwide Loan. The Excess Servicing Fee payable to PNC
will range from 0.000% to 0.700% per annum of the Stated Principal Balance of
each PNC Loan. The Servicers are obligated to pay certain ongoing expenses
associated with the Trust Fund and incurred by the Servicers in connection with
their responsibilities under the Agreement and such amounts will be paid by the
related Servicer out of their respective Servicing Fees. The amount of the
Servicing Fee is subject to adjustment with respect to prepaid Mortgage Loans,
as described herein under ' -- Adjustment to Servicing Fee in Connection with
Certain Prepaid Mortgage Loans.' The related Servicer will also be entitled to
receive late payment fees, prepayment penalty fees, assumption fees and other
similar charges. Each Servicer will be entitled to receive all reinvestment
income earned on amounts on deposit in the related Collection Account.
 
     The 'Net Rate' of a Mortgage Loan is the Mortgage Rate thereof minus the
related Expense Fee Rate. The 'Mortgage Rate' of a Mortgage Loan is the rate at
which interest accrues thereon in accordance with the terms of the related
Mortgage Note.
 
ADJUSTMENT TO SERVICING FEE IN CONNECTION WITH CERTAIN PREPAID MORTGAGE LOANS
 
     When a principal prepayment in full (a 'Payoff') is made on a Mortgage
Loan, the Mortgagor is charged interest only for the period from the Due Date of
the immediately preceding monthly payment up to the date of such prepayment,
instead of for a full month. Partial principal prepayments ('Curtailments') are
generally
 
                                      S-25
 

<PAGE>

<PAGE>
applied as of the day of receipt, with a resulting reduction in interest payable
for the month during which the Curtailment is made. With respect to Payoffs and
Curtailments in respect of the First Nationwide Loans, First Nationwide, as
Servicer, is obligated to remit to the Trust Fund an amount equal to the lesser
of (a) any shortfall in interest collections resulting from the timing of
Payoffs and Curtailments made during the calendar month preceding a Distribution
Date, and (b) the monthly Servicing Fee otherwise payable to First Nationwide,
as Servicer, in connection with such Distribution Date. With respect to Payoffs
in respect of the PNC Loans, PNC, as Servicer, is obligated to remit to the
Trust Fund an amount equal to the lesser of (a) any shortfall in interest
collections resulting from the timing of Payoffs made from the 15th day of the
calendar month preceding the month of a Distribution Date to the last day of
such preceding month, and (b) the sum of (i) a portion of the Servicing Fee for
such Distribution Date equal to 0.04% per annum of the aggregate Stated
Principal Balance of the PNC Loans as of the Due Date in the month of such
Distribution Date, (ii) any reinvestment income realized by PNC relating to
Payoffs in respect of the PNC Loans made during the related Prepayment Period,
and (iii) interest payments on Payoffs in respect of the PNC Loans received
during the period from the first day through the 14th day of the month of such
Distribution Date. If shortfalls in interest as a result of Payoffs and
Curtailments during the Prepayment Periods applicable to a Distribution Date
exceed the amount of the Servicing Fees payable to First Nationwide or, with
respect to the PNC Loans, the available portion of its Servicing Fee as
calculated above and other amounts described above available to cover such
shortfall for such Distribution Date (collectively, 'Compensating Interest'),
the amount of interest available to be distributed to Certificateholders will be
reduced by the amount of such excess. See 'Description of the Certificates --
Distributions of Interest' herein.
 
ADVANCES
 
     Subject to the following limitations, each Servicer will be required to
advance prior to each Distribution Date, from its own funds or amounts received
with respect to the Mortgage Loans that do not constitute Available Funds for
such Distribution Date, an amount equal to the aggregate of payments of
principal of and interest on the Mortgage Loans (net of the related Servicing
Fee) which were due on the related Due Date and which were delinquent on the
related Determination Date (any such advance, an 'Advance').
 
     Advances are intended to maintain a regular flow of scheduled interest and
principal payments on the Certificates rather than to guarantee or insure
against losses. The related Servicer is obligated to make Advances with respect
to delinquent payments of principal of or interest on each Mortgage Loan to the
extent that such Advances are, in its reasonable judgment, recoverable from
future payments and collections or insurance payments or proceeds of liquidation
of the related Mortgage Loan. Subject to the foregoing, Advances will be made
through the liquidation of the related Mortgaged Property. If the related
Servicer determines on any Determination Date to make an Advance, such Advance
will be included with the distribution to Certificateholders on the related
Distribution Date. Any failure by either Servicer to make an Advance as required
under the Agreement will constitute an Event of Default under the Agreement
subject to grace periods specified therein. If either Servicer is terminated as
a result of the occurrence of an Event of Default, the Trustee or the successor
servicer will be obligated to make any such Advance, in accordance with the
terms of the Agreement. For a discussion of other Events of Default under the
Agreement and the rights of the Trustee upon any Event of Default, see 'The
Agreements -- Event of Default and Rights Upon Events of Default' in the
Prospectus.
 
OPTIONAL PURCHASE OF DEFAULTED LOANS
 
     Each Servicer may, at its option, purchase from the Trust Fund any Mortgage
Loan serviced by it which is delinquent 91 days or more and First Nationwide may
purchase any First Nationwide Loan with respect to which foreclosure actions
have commenced or becomes REO Property. Any such purchase shall be at a price
equal to 100% of the Stated Principal Balance of such Mortgage Loan plus accrued
interest thereon at the applicable Mortgage Rate from the date through which
interest was last paid by the related Mortgagor to the first day of the month in
which such amount is to be distributed or, with respect to any REO Property,
based on its fair market value.
 
SPECIAL SERVICING AGREEMENTS
 
     The Agreement will permit each Servicer to enter into a special servicing
agreement with an unaffiliated holder of Subordinate Certificates. Pursuant to
such an agreement, such holder may instruct the related Servicer,
 
                                      S-26
 

<PAGE>

<PAGE>
to commence or delay foreclosure proceedings with respect to delinquent Mortgage
Loans being serviced by it. Such commencement or delay at such holder's
direction will be taken by the related Servicer, only after such holder deposits
a specified amount of cash with such Servicer. Such cash will be available for
payment to related Certificateholders if Liquidation Proceeds are less than they
otherwise may have been had such Servicer acted pursuant to its normal servicing
procedures.
 
VOTING RIGHTS
 
     Voting rights of the Trust Fund in general will be allocated 1% to each
Class of Notional Amount Certificates with the balance allocated among the other
Classes of Certificates based upon their respective Class Principal Balances.

                        DESCRIPTION OF THE CERTIFICATES
 
GENERAL
 
     The Certificates will be issued pursuant to the Agreement. Set forth below
are summaries of the specific terms and provisions pursuant to which the
Certificates will be issued. The following summaries do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, the provisions of the Agreement. When particular provisions or terms used in
the Agreement are referred to, the actual provisions (including definitions of
terms) are incorporated by reference.
 
     The Mortgage Pass-Through Certificates, Series 1999-3 will consist of the
Class IPP-A, Class IIPP-A-1, Class IIPP-A-2, Class IIPP-A-3, Class III-A-1,
Class III-A-2, Class III-A-3, Class III-A-4, Class III-A-5, Class III-A-6,
Class II-P, Class III-P, Class III-X and Class A-R Certificates (collectively,
the 'Senior Certificates') and the Class C-B-1, Class C-B-2, Class C-B-3, Class
C-B-4, Class C-B-5, Class C-B-6, Class III-B-1, Class III-B-2, Class III-B-3,
Class III-B-4, Class III-B-5 and Class III-B-6 Certificates (collectively, the
'Subordinate Certificates'). The Senior Certificates and the Subordinate
Certificates are collectively referred to herein as the 'Certificates.' Only the
Senior Certificates and the Class C-B-1, Class C-B-2, Class C-B-3, Class
III-B-1, Class III-B-2 and Class III-B-3 Certificates (collectively, the
'Offered Certificates') are offered hereby. The Classes of Offered Certificates
will have the respective initial Class Principal Balances or initial Notional
Amounts (subject to the permitted variance) and Pass-Through Rates set forth or
described on page S-3 hereof.
 
     The 'Class Principal Balance' of any Class of Certificates as of any
Distribution Date is the initial Class Principal Balance thereof reduced by the
sum of (i) all amounts previously distributed to holders of Certificates of such
Class as payments of principal, (ii) the amount of Realized Losses (including
Excess Losses) allocated to such Class and (iii) in the case of any Subordinate
Certificates any amounts allocated to such Class in reduction of its Class
Principal Balance in respect of payment of Class PO Deferred Amounts or certain
other adjustments, each as described below under ' -- Allocation of Losses.' The
Notional Amount Certificates do not have a principal balance and are not
entitled to any distributions in respect of principal of the Mortgage Loans.
 
     The Senior Certificates for each Certificate Group will evidence in the
aggregate an initial beneficial ownership interest of approximately 96.10% for
the Group I Certificates, 96.10% for the Group II Certificates and 93.00% for
the Group III Certificates of the Mortgage Loans in the related Loan Group as of
the Closing Date. Each Class of Subordinate Certificates as of the Closing Date,
represents an initial beneficial ownership interest in the Group I and Group II
Loans, with respect to the Group C-B Certificates and the Group III Loans, with
respect to the Group III-B Certificates approximately as follows:

     The Book-Entry Certificates will be issuable in book-entry form only. The
Physical Certificates will be issued in fully registered certificated form. The
Class A-R Certificates will be issued as a single certificate with a dollar
denomination of $100.
 
SEPARATE REMIC STRUCTURE
 
     For federal income tax purposes, the Trust Fund will include two segregated
asset pools, each of which will be treated as a separate REMIC. The assets of
the Subsidiary REMIC will generally consist of the Mortgage Loans. The assets of
the Master REMIC will generally consist of uncertificated regular interests
issued by the Subsidiary REMIC, which in the aggregate will correspond to the
Certificates.

BOOK-ENTRY CERTIFICATES
 
     Each Class of Book-Entry Certificates will be issued in one or more
certificates which equal the aggregate initial Class Principal Balance of each
such Class of Certificates and which will be held by a nominee of The Depository
Trust Company (together with any successor depository selected by the Depositor,
the 'Depository'). Beneficial interests in the Book-Entry Certificates will be
held indirectly by investors through the book-entry facilities of the
Depository, as described herein. Investors in the Book-Entry Certificates, other
than the Class III-A-2, Class III-A-6, Class C-B-1, Class III-B-1 and Class X
Certificates, may hold such beneficial interests in the Book-Entry Certificates
in minimum denominations representing an original principal amount of not less
than $25,000 and multiples of $1 in excess thereof. Investors in the Class
III-A-2, Class C-B-1 and Class III-B-1 Certificates may hold such beneficial
interests in the Book-Entry Certificates in minimum denominations representing
an original principal amount of not less than $1,000 and multiples of $1 in
excess thereof. Investors in the Class III-A-6 and Class X Certificates may hold
such beneficial interests in the Book-Entry Certificates in minimum
denominations representing an original notional amount of not less than $100,000
and multiples of $1 in excess thereof. The Depositor has been informed by the
Depository that its nominee will be CEDE & Co. ('CEDE'). Accordingly, CEDE is
expected to be the holder of record of the Book-Entry Certificates. Except as
described below, no person acquiring a Book-Entry Certificate (each, a
'beneficial owner') will be entitled to receive a physical certificate
representing such Certificate (a 'Definitive Certificate').
 
     Unless and until Definitive Certificates are issued, it is anticipated that
the only 'Certificateholder' of the Book-Entry Certificates will be CEDE, as
nominee of the Depository. Beneficial owners of the Book-Entry Certificates will
not be Certificateholders, as that term is used in the Agreement. Beneficial
owners are only permitted to exercise the rights of Certificateholders
indirectly through Participants (as defined in the Prospectus) and the
Depository. Monthly and annual reports on the Trust Fund provided to CEDE, as
nominee of the Depository, may be made available to beneficial owners upon
request, in accordance with the rules, regulations and procedures creating and
affecting the Depository, and to the Participants to whose Depository accounts
the Book-Entry Certificates of such beneficial owners are credited.
 
     For a description of the procedures generally applicable to the Book-Entry
Certificates, see 'Description of the Securities -- Book-Entry Registration' in
the Prospectus.
 
     Definitive Certificates will be issued to beneficial owners of Book-Entry
Certificates, or their nominees, rather than to the Depository, only if (a) the
Depository or the Depositor advises the Trustee in writing that the Depository
is no longer willing, qualified or able to discharge properly its
responsibilities as nominee and depository with respect to the Book-Entry
Certificates and the Depositor or the Trustee is unable to locate a qualified
successor; (b) the Depositor, at its sole option, in writing, elects to
terminate the book-entry system through the Depository; or (c) after the
occurrence of an Event of Default beneficial owners of any Class of Book-Entry
Certificates representing not less than 51% of the related aggregate Class
Principal Balance advise the Trustee and the Depository through the Participants
in writing that the continuation of a book-entry system through the Depository
(or a successor thereto) is no longer in the best interests of the beneficial
owners.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all beneficial
owners of the occurrence of such event and the availability of Definitive
Certificates. Upon surrender by the Depository of the global certificate or
certificates representing the Book-Entry Certificates and instructions for
re-registration, the Trustee will issue the Definitive Certificates, and
thereafter the Trustee will recognize the holders of such Definitive
Certificates as Certificateholders under the Agreement.
 
     DTC management is aware that some computer applications, systems, and the
like for processing data ('Systems') that are dependent upon calendar dates,
including dates before, on, and after January 1, 2000, may encounter 'Year 2000
problems.' DTC has informed its Participants and other members of the financial
community (the 'Industry') that it has developed and is implementing a program
so that its Systems, as the same relate to the timely payment of distributions
(including principal and income payments) to securityholders, book-entry
deliveries, and settlement of trades within DTC ('DTC Services'), continue to
function appropriately. This program includes a technical assessment and a
remediation plan, each of which is complete. Additionally, DTC's plan includes a
testing phase, which is expected to be completed within appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors from whom DTC licenses software and hardware, and
third party vendors on whom DTC relies for information of the provision of
services, including telecommunication and electrical utility service providers,
among others. DTC has informed the Industry that it is contacting (and will
continue to contact) third party vendors from whom DTC acquires services to:
(i) impress upon them the importance of such services being year 2000 compliant;
and (ii) determine the extent of their efforts for Year 2000 remediation (and,
as appropriate, testing) of their services. In addition, DTC is in the process
of developing such contingency plans as it deems appropriate.
 
     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.
 
PAYMENTS ON MORTGAGE LOANS; ACCOUNTS
 
     On or prior to the Closing Date, the Trustee will establish an account (the
'Certificate Account'), which shall be maintained with the Trustee in trust for
the benefit of the Certificateholders. On or prior to each Distribution Date, as
specified in the Agreement, each Servicer will withdraw from the related
Collection Account the portion of the aggregate Available Funds for each Loan
Group on deposit in such Collection Account for such Distribution Date and will
deposit such amounts in the Certificate Account. See 'The Trust
Funds -- Collection Account and Certificate Account' in the Prospectus.
 
DISTRIBUTIONS
 
     Distributions on the Certificates will be made by the Trustee on the 19th
day of each month, with respect to the Group I and Group II Certificates, and on
the 25th of each month, with respect to the Group III Certificates, or if either
such day is not a business day, on the first business day thereafter, commencing
in May 1999 (each, a 'Distribution Date'), to the persons in whose names such
Certificates are registered at the close of business on the last business day of
the month preceding the month of such Distribution Date (the 'Record Date').
 
     Distributions on each Distribution Date will be made by check mailed to the
address of the person entitled thereto as it appears on the applicable
certificate register or, in the case of a Certificateholder who holds 100% of a
Class of Certificates or who holds a Notional Amount Certificate or who holds
Certificates with an aggregate initial certificate balance of $1,000,000 or more
and who has so notified the Trustee in writing in accordance with the Agreement,
by wire transfer in immediately available funds to the account of such
Certificateholder at a bank or other depository institution having appropriate
wire transfer facilities; provided, however, that the final distribution in
retirement of the Certificates will be made only upon presentment and surrender
of such Certificates at the Corporate Trust Office of the Trustee.
 
PRIORITY OF DISTRIBUTIONS AMONG CERTIFICATES
 
     Distributions with respect to a Certificate Group will in general be made
to the extent of the Available Funds for the related Loan Group in the order and
priority as follows: (1) first, to the related Class P Certificates, if any, a
certain portion of the principal received in respect of each related Class P
Mortgage Loan, as described in ' -- Distributions of Principal' herein; (2)
second, to the Senior Certificates of such Certificate Group entitled to
interest, accrued and unpaid interest, as described in ' -- Interest' herein;
(3) third, to the Senior Certificates of such Certificate Group entitled to
principal (other than the related Class P Certificates, if any), principal in
the order described for the Senior Certificates of such Certificate Group as set
forth in ' -- Distributions of Principal -- Senior Principal Distribution
Amount;' (4) fourth, to the Class P Certificates, if any, of such Certificate
Group, any related Class PO Deferred Amounts; (5) fifth, to each Class of
Subordinate Certificates of such Certificate Group, interest and then principal
in increasing order of numerical Class designation, with both interest and
principal being paid to one Class before any payments are made to the next
Class; provided, however; that since the Group C-B Certificates relate to the
Group I and Group II Loans, such Certificates receive payments from the
remaining Available Funds for the Group I and Group II Loans; and (6) sixth, to
the Class A-R Certificates, the remainder (which is expected to be zero) of all
Available Funds.
 
                                      S-30
 

<PAGE>

<PAGE>
     Under the limited circumstances described herein under
' -- Cross-Collateralization,' distributions of interest and principal to the
Group I Senior and Group II Senior Certificates will be based on payments
received or advanced with respect to the Group II and Group I Loans,
respectively.
 
     'Available Funds' with respect to any Distribution Date and the Mortgage
Loans in a Loan Group will be equal to the sum of (i) all scheduled installments
of interest (net of the related Expense Fees) and principal due on the Due Date
in the month in which such Distribution Date occurs and received prior to the
related Determination Date, together with any Advances in respect thereof; (ii)
all proceeds of any primary mortgage guaranty insurance policies and any other
insurance policies with respect to the Mortgage Loans, to the extent such
proceeds are not applied to the restoration of the related Mortgaged Property or
released to the Mortgagor in accordance with the applicable Servicer's normal
servicing procedures (collectively, 'Insurance Proceeds') and all other cash
amounts received and retained in connection with the liquidation of defaulted
Mortgage Loans, by foreclosure or otherwise ('Liquidation Proceeds') during the
month preceding the month of such Distribution Date (in each case, net of
unreimbursed expenses incurred in connection with a liquidation or foreclosure
and unreimbursed Advances, if any); (iii) all partial or full prepayments
received during the related Prepayment Period applicable to such Distribution
Date, exclusive of prepayment penalties; (iv) amounts received with respect to
such Distribution Date as the Substitution Adjustment Amount or Purchase Price
in respect of a Deleted Mortgage Loan or a Mortgage Loan repurchased by a Seller
or a Servicer as of such Distribution Date, reduced (in the case of clauses (i)
through (iv) above) by amounts in reimbursement for Advances previously made and
other amounts as to which each Servicer is entitled to be reimbursed pursuant to
the Agreement; and (v) any amounts payable as Compensating Interest by such
Servicer on such Distribution Date relating to such Mortgage Loans.
 
DISTRIBUTIONS OF INTEREST
 
     The Pass-Through Rate for each interest-bearing Class of Offered
Certificates for each Distribution Date (the 'Pass-Through Rate') is as set
forth or described on page S-3 hereof.
 
     The Class P Certificates will not be entitled to receive any distributions
of interest.
 
     The interest payable to the Class III-X Certificates is based on the
weighted average of the Stripped Interest Rates of the Group III Loans having
Net Rates in excess of 6.75% per annum (the 'Group III Premium Rate Mortgage
Loans'). The 'Stripped Interest Rate' means for any Group III Premium Rate
Mortgage Loan, the excess, if any, of the Net Rate for such Mortgage Loan over
6.75%.
 
     The Notional Amount for the Class III-X Certificates with respect to any
Distribution Date will equal the product of (x) the aggregate Stated Principal
Balance, as of the second preceding Due Date after giving effect to Scheduled
Payments for such Due Date, whether or not received, or with respect to the
initial Distribution Date, as of the Cut-off Date, of the Group III Premium Rate
Mortgage Loans and (y) a fraction, the numerator of which is the weighted
average of the Stripped Interest Rates for the Group III Premium Rate Mortgage
Loans as of such Due Date and the denominator of which is 6.75%.
 
     The Notional Amount of the Class III-A-6 Certificates for any Distribution
Date will equal the product of (a) the Class Principal Balance of the Class
III-A-4 Certificates and (b) 0.20 divided by 6.75.
 
     On each Distribution Date, to the extent of funds available therefor, each
interest-bearing Class of Certificates will be entitled to receive an amount
allocable to interest (as to each such Class, the 'Interest Distribution
Amount') with respect to the related Interest Accrual Period. The Interest
Distribution Amount for any interest-bearing Class will be equal to the sum of
(i) interest at the applicable Pass-Through Rate on the related Class Principal
Balance or Notional Amount, as the case may be, and (ii) the sum of the amounts,
if any, by which the amount described in clause (i) above on each prior
Distribution Date exceeded the amount actually distributed as interest on such
prior Distribution Dates and not subsequently distributed. The Class P
Certificates will not bear interest.
 
     With respect to each Distribution Date, the 'Interest Accrual Period' for
each interest-bearing Class of Certificates will be the calendar month preceding
the month of such Distribution Date.
 
     The interest entitlement described above for each interest-bearing Class of
Certificates will be reduced by 'Net Interest Shortfalls' experienced by the
related Loan Group or, with respect to the Group C-B Certificates, the related
Loan Groups, for such Distribution Date.

     With respect to any Distribution Date, the 'Net Interest Shortfall' for a
Loan Group is equal to the sum of (i) the amount of interest which would
otherwise have been received with respect to any Mortgage Loan in such Loan
Group that was the subject of (x) a Relief Act Reduction or (y) a Special Hazard
Loss, Fraud Loss, Debt Service Reduction or Deficient Valuation, after the
exhaustion of the respective amounts of coverage provided by the applicable
Subordinate Certificates for such types of losses and (ii) any Net Prepayment
Interest Shortfalls. Net Interest Shortfalls for a Loan Group on any
Distribution Date will be allocated pro rata among all Classes of Certificates
in the related Certificate Group entitled to receive distributions of interest
on such Distribution Date from the related Loan Group, based on the amount of
interest each such Class of Certificates would otherwise be entitled to receive
on such Distribution Date in respect of such Loan Group before taking into
account any reduction in such amounts resulting from such Net Interest
Shortfalls. The amount of interest a Class of Group C-B Certificates would
otherwise be entitled to receive from either the Group I or Group II Loans
before taking into account any such reduction will be based upon the amount of
interest accruing at the applicable Pass-Through Rate on such Class'
proportionate share (based upon Class Principal Balance) of the applicable
Group C-B Loan Group Component Balance for such Distribution Date. A 'Relief Act
Reduction' is a reduction in the amount of monthly interest payment on a
Mortgage Loan pursuant to the Soldiers' and Sailors' Civil Relief Act of 1940.
See 'Certain Legal Aspects of Loans -- Anti-Deficiency Legislation and Other
Limitations on Lenders -- Soldiers' and Sailors' Civil Relief Act' in the
Prospectus. With respect to any Distribution Date, the 'Net Prepayment Interest
Shortfall' for a Loan Group is the amount by which the aggregate of Prepayment
Interest Shortfalls experienced by the related Loan Group during the applicable
Prepayment Period applicable to such Distribution Date exceeds the available
Compensating Interest for such Loan Group for such period. A 'Prepayment
Interest Shortfall' is the amount by which interest paid by a borrower in
connection with a prepayment of principal on a Mortgage Loan is less than one
month's interest at the related Mortgage Rate (net of the related Servicing Fee)
on the Stated Principal Balance of such Mortgage Loan.
 
     Accrued interest to be distributed on any Distribution Date will be
calculated on the basis of the related Class Principal Balance or Notional
Amount, as applicable, immediately prior to such Distribution Date. Interest
will be calculated and payable on the basis of a 360-day year divided into
twelve 30-day months.
 
     In the event that, on a particular Distribution Date, Available Funds for a
Loan Group applied in the order described above under ' -- Priority of
Distributions Among Certificates' are not sufficient to make a full distribution
of the interest entitlement on the Certificates of the related Certificate
Group, interest will be distributed on each Class of Certificates of equal
priority based on the amount of interest each such Class would otherwise have
been entitled to receive in the absence of such shortfall. Any such unpaid
amount will be carried forward and added to the amount holders of each such
Class of Certificates will be entitled to receive on the next Distribution Date.
Such a shortfall could occur, for example, if losses realized on the Mortgage
Loans for the related Loan Group were exceptionally high or were concentrated in
a particular month. Any such unpaid amount will not bear interest.
 
DISTRIBUTIONS OF PRINCIPAL
 
     General. On each Distribution Date, Certificateholders of each Certificate
Group will be entitled to receive principal distributions from the related
Available Funds to the extent and in the priority described herein. See
' -- Priority of Distributions Among Certificates' herein. The Group I Senior
and Group II Senior Certificates will receive principal collected from the
Group I and Group II Loans, respectively, except in the limited circumstances
described herein under ' -- Cross-Collateralization.' The Group III Certificates
will receive principal collected from the Group III Loans. The Group C-B
Certificates will receive principal collected from the Group I and Group II
Loans.
 
     For any Distribution Date and Loan Group, the 'Principal Payment Amount' is
the sum with respect to the Mortgage Loans in such Loan Group of (i) scheduled
principal payments on the Mortgage Loans due on the related Due Date, (ii) the
principal portion of repurchase proceeds received with respect to any Mortgage
Loan which was repurchased as permitted or required by the Agreement during the
calendar month preceding the month of the Distribution Date and (iii) any other
unscheduled payments of principal which were received on the Mortgage Loans
during the preceding calendar month, other than Payoffs, Curtailments or
Liquidation Principal (as defined below). For any Distribution Date and Loan
Group, the 'Principal Prepayment Amount' is
 
                                      S-32
 

<PAGE>

<PAGE>
the sum with respect to the Mortgage Loans in such Loan Group of all Payoffs and
Curtailments relating to the Mortgage Loans in such Loan Group which were
received during the related Prepayment Period.
 
     With respect to each Distribution Date and each Payoff with respect to a
First Nationwide Loan, the related 'Prepayment Period' will be the calendar
month preceding the month in which the related Distribution Date occurs. With
respect to each Distribution Date and each Payoff with respect to a PNC Loan,
the related 'Prepayment Period' will commence on the 15th day of the month
preceding the month in which the related Distribution Date occurs (or, in the
case of the first Distribution Date, commencing on the Cut-off Date) and will
end on the 14th day of the month in which such Distribution Date occurs. With
respect to each Distribution Date and each Curtailment, the related 'Prepayment
Period' will be the month preceding the month in which the related Distribution
Date occurs.
 
     'Liquidation Principal' is the principal portion of Liquidation Proceeds
received with respect to each Mortgage Loan which became a Liquidated Mortgage
Loan (but not in excess of the principal balance thereof) during the calendar
month preceding the month of the Distribution Date, exclusive of the portion
thereof attributable to the applicable Class P Principal Distribution Amount, if
any. A 'Liquidated Mortgage Loan' is a defaulted Mortgage Loan as to which the
applicable Servicer has determined that all amounts which it expects to recover
from or on account of such Mortgage Loan, whether from Insurance Proceeds,
Liquidation Proceeds or otherwise have been recovered.
 
     The Notional Amount Certificates will not be entitled to receive any
distributions of principal.
 
     Senior Principal Distribution Amount. On each Distribution Date, to the
extent of Available Funds therefor, up to the amount of the related Senior
Principal Distribution Amount for such Certificate Group for such Distribution
Date, will be distributed as principal:
 
          (A) with respect to the Group I Certificates, to the Class IPP-A
     Certificates, until the Class Principal Balance thereof has been reduced to
     zero;
 
          (B) with respect to the Group II Certificates, to the following
     Classes of Senior Certificates in the following order of priority:
 
             (i) to the Class IIPP-A-3 Certificates, the Class IIPP-A-3 Lockout
        Principal Distribution Amount, until the Class Principal Balance thereof
        has been reduced to zero;
 
             (ii) to the Class A-R Certificates, until the Class Principal
        Balance thereof has been reduced to zero;
 
             (iii) sequentially, to the Class IIPP-A-1 and Class IIPP-A-2
        Certificates, in that order, until the respective Class Principal
        Balance thereof is reduced to zero; and
 
             (iv) to the Class IIPP-A-3 Certificates, any remaining portion of
        such Senior Principal Distribution Amount, until the Class Principal
        Balance thereof has been reduced to zero;
 
          (C) with respect to the Group III Certificates, to the following
     Classes of Senior Certificates in the following order of priority:
 
             (i) to the Class III-A-3 Certificates, the Class III-A-3 Lockout
        Principal Distribution Amount, until the Class Principal Balance thereof
        has been reduced to zero;
 
             (ii) concurrently, until the Class Principal Balance of the Class
        III-A-5 Certificates has been reduced to zero:
 
                (a) 20.7856008470% to the Class III-A-5 Certificates; and
 
                (b) 79.2143991530%, sequentially:
 
                    (1) concurrently, until the Class Principal Balance of the
               Class III-A-4 Certificates has been reduced to zero:
 
                        (a) 22.7262544803% to the Class III-A-1 Certificates;
                   and
 
                        (b) 77.2737455197% to the Class III-A-4 Certificates;
                   and
 
                    (2) to the Class III-A-1 Certificates;
 
             (iii) concurrently, until the Class Principal Balance of the Class
        III-A-4 Certificates has been reduced to zero:
 
                                      S-33

<PAGE>
                (a) 22.7262544803% to the Class III-A-1 Certificates; and
 
                (b) 77.2737455197% to the Class III-A-4 Certificates;
 
             (iv) to the Class III-A-1 Certificates, until the Class Principal
        Balance thereof has been reduced to zero;
 
             (v) to the Class III-A-2 Certificates, until the Class Principal
        Balance thereof has been reduced to zero; and
 
             (vi) to the Class III-A-3 Certificates, any remaining portion of
        such Senior Principal Distribution Amount, until the Class Principal
        Balance thereof has been reduced to zero.
 
     Notwithstanding the foregoing, on each Distribution Date on and after the
Senior Credit Support Depletion Date for the Group II Certificates, the Senior
Principal Distribution Amount for such Certificate Group will be distributed,
concurrently, as principal of the Classes of the Group II Senior Certificates
(other than the Class II-P Certificates) pro rata, in accordance with their
respective Class Principal Balances immediately prior to such Distribution Date.
 
     Notwithstanding the foregoing, on each Distribution Date on and after the
Senior Credit Support Depletion Date for the Group III Certificates, the Senior
Principal Distribution Amount for such Certificate Group will be distributed,
concurrently, as principal of the Classes of the Group III Senior Certificates
(other than the Class III-P Certificates) pro rata, in accordance with their
respective Class Principal Balances immediately prior to such Distribution Date.
 
     The 'Senior Credit Support Depletion Date' for a Certificate Group is the
date on which the aggregate Class Principal Balance of the Group C-B
Certificates, in the case of the Group I and Group II Certificates, or the Group
III-B Certificates, in the case of the Group III Certificates, has been reduced
to zero.
 
     The 'Senior Principal Distribution Amount' for any Distribution Date and
Certificate Group will equal the sum of (i) the related Senior Percentage of the
Principal Payment Amount for the related Loan Group (exclusive of the portion
thereof attributable to the applicable Class P Principal Distribution Amount, if
any), (ii) the related Senior Prepayment Percentage of the Principal Prepayment
Amount for the related Loan Group (exclusive of the portion thereof attributable
to the applicable Class P Principal Distribution Amount, if any), and (iii) the
Senior Liquidation Amount for the related Loan Group.
 
     The 'Senior Liquidation Amount' for a Loan Group is the aggregate, for each
Mortgage Loan in such Loan Group which became a Liquidated Mortgage Loan during
the calendar month preceding the month of the Distribution Date, of the lesser
of (i) the Senior Percentage for the related Certificate Group of the Stated
Principal Balance of such Mortgage Loan (exclusive of the related Class P
Fraction thereof, if applicable) and (ii) the Senior Prepayment Percentage for
the related Certificate Group of the Liquidation Principal with respect to such
Mortgage Loan.
 
     'Stated Principal Balance' means, as to any Mortgage Loan and Due Date, the
unpaid principal balance of such Mortgage Loan as of such Due Date, as specified
in the amortization schedule at the time relating thereto (before any adjustment
to such amortization schedule by reason of any moratorium or similar waiver or
grace period), after giving effect to any previous partial principal prepayments
and Liquidation Proceeds (to the extent allocable to principal) received and to
the payment of principal due on such Due Date and irrespective of any
delinquency in payment by the related Mortgagor.
 
     The 'Senior Percentage' for any Distribution Date for a Certificate Group
is the percentage equivalent of a fraction the numerator of which is the
aggregate Class Principal Balance of the Classes of Senior Certificates of such
Certificate Group (other than the related Class P Certificates, if any)
immediately prior to such date and the denominator of which is the aggregate
Stated Principal Balance of the Mortgage Loans in the related Loan Group (less
the applicable Class P Principal Balance, if any), as of the Due Date in the
month of such Distribution Date; provided, however, in no event will the Senior
Percentage for a Certificate Group exceed 100%. The 'Subordinate Percentage' for
a Certificate Group for any Distribution Date will be calculated as the
difference between 100% and the related Senior Percentage for such date.
 
     The Senior Prepayment Percentage for any Distribution Date for a
Certificate Group occurring during the five years beginning on the first
Distribution Date will equal 100%. Thereafter, such Senior Prepayment Percentage
will, except as described below, be subject to gradual reduction as described in
the following paragraph. This disproportionate allocation of certain unscheduled
payments in respect of principal will have the
 
                                      S-34
 

<PAGE>

<PAGE>
effect of accelerating the amortization of the Senior Certificates in a
Certificate Group while, in the absence of Realized Losses, increasing the
interest in the aggregate Stated Principal Balance of the applicable Loan Group
evidenced by the related Class or Classes of Subordinate Certificates in such
Certificate Group. Increasing the respective interest of such Subordinate
Certificates relative to that of the related Senior Certificates is intended to
preserve the availability of the subordination provided by such Subordinate
Certificates.
 
     The Senior Prepayment Percentage for any Distribution Date for a
Certificate Group occurring on or after the fifth anniversary of the first
Distribution Date will be as follows: for any Distribution Date in the first
year thereafter, the related Senior Percentage plus 70% of the related
Subordinate Percentage for such Distribution Date; for any Distribution Date in
the second year thereafter, the related Senior Percentage plus 60% of the
related Subordinate Percentage for such Distribution Date; for any Distribution
Date in the third year thereafter, the related Senior Percentage plus 40% of the
related Subordinate Percentage for such Distribution Date; for any Distribution
Date in the fourth year thereafter, the related Senior Percentage plus 20% of
the related Subordinate Percentage for such Distribution Date; and for any
Distribution Date thereafter, the related Senior Percentage for such
Distribution Date (unless on any of the foregoing Distribution Dates the related
Senior Percentage exceeds the initial Senior Percentage for the Senior
Certificates of such Certificate Group, in which case such Senior Prepayment
Percentage for such Distribution Date will once again equal 100%). In the event
the Senior Prepayment Percentage for the Group I or Group II Certificates will
once again equal 100% in accordance with the parenthetical in the preceding
sentence, the Senior Prepayment Percentage for the other Certificate Group will
also equal 100%.
 
     Notwithstanding the foregoing no decrease in the reduction to the Senior
Prepayment Percentage for the Senior Certificates of a Certificate Group as
described above will occur if as of the first Distribution Date as to which any
such decrease applies (i) with respect to each Certificate Group, the
outstanding principal balance of the related Mortgage Loans, delinquent 60 days
or more (averaged over the preceding six month period), as a percentage of the
aggregate principal balance of, with respect to the Group I or Group II
Certificates, the related Group C-B Loan Group Component Balance as of such
Distribution Date or, with respect to the Group III Certificates, the Group
III-B Certificates as of such Distribution Date, is equal to or greater than 50%
or (ii) cumulative Realized Losses with respect to the Mortgage Loans in the
related Loan Group exceed (a) with respect to the Distribution Date on the fifth
anniversary of the first Distribution Date, 30% of the aggregate principal
balance of, with respect to the Group I Certificates or Group II Certificates,
the related Group C-B Loan Group Component Balance or, with respect to the
Group III Certificates, the Group III-B Certificates, as of the Closing Date
(each, an 'Original Subordinate Principal Balance'), (b) with respect to the
Distribution Date on the sixth anniversary of the first Distribution Date, 35%
of such Original Subordinate Principal Balance, (c) with respect to the
Distribution Date on the seventh anniversary of the first Distribution Date, 40%
of such Original Subordinate Principal Balance, (d) with respect to the
Distribution Date on the eighth anniversary of the first Distribution Date, 45%
of such Original Subordinate Principal Balance and (e) with respect to the
Distribution Date on the ninth anniversary of the first Distribution Date, 50%
of such Original Subordinate Principal Balance. In the event that the Senior
Prepayment Percentage for the Group I or Group II Certificates is not permitted
to reduce due to the limitations set forth above, the Senior Prepayment
Percentage for the other Certificate Group will also be prevented from any such
reduction.
 
     If on any Distribution Date the allocation to the Class of Senior
Certificates of a Certificate Group then entitled to distributions of Payoffs
and Curtailments and other amounts in the percentage required above would reduce
the outstanding Class Principal Balance of such Class below zero, the
distribution to such Class of Certificates of the related Senior Prepayment
Percentage of such amounts for such Distribution Date will be limited to the
percentage necessary to reduce the related Class Principal Balance to zero.
 
     Class IIPP-A-3 Lockout Principal Distribution Amount. The 'Class IIPP-A-3
Lockout Principal Distribution Amount' for any Distribution Date will equal the
sum of (i) the Class IIPP-A-3 Adjusted Percentage of the Principal Payment
Amount of the Group II Loans (exclusive of the portion thereof attributable to
the Class II-P Principal Distribution Amount), (ii) the Class IIPP-A-3
Prepayment Percentage of the Principal Prepayment Amount for the Group II Loans
(exclusive of the portion thereof attributable to the Class II-P Principal
Distribution Amount) and (iii) the Class IIPP-A-3 Liquidation Amount (as defined
below).
 
     The 'Class IIPP-A-3 Adjusted Percentage' will equal (i) 0% for any
Distribution Date occurring prior to the Distribution Date in May 2004 and (ii)
the Class IIPP-A-3 Percentage (as defined below) for any Distribution Date
occurring on or after the Distribution Date in May 2004.

     The 'Class IIPP-A-3 Percentage' for any Distribution Date is equal to the
lesser of (a) 100% and (b) the Class Principal Balance of the Class IIPP-A-3
Certificates immediately prior to such date divided by the aggregate Stated
Principal Balance of the Group II Loans (less the Class II-P Principal Balance),
as of the Due Date in the month of such Distribution Date. The Class IIPP-A-3
Percentage as of the Closing Date will be approximately 9.61%.
 
     The 'Class IIPP-A-3 Liquidation Amount' is the aggregate, for each Group II
Loan which became a Liquidated Mortgage Loan during the calendar month preceding
the month of the Distribution Date, of the lesser of (i) the Class IIPP-A-3
Percentage of the Stated Principal Balance of such Mortgage Loan (exclusive of
the Class II-P Fraction thereof, with respect to any Class II-P Mortgage Loan)
and (ii) the Class IIPP-A-3 Percentage of the Liquidation Principal with respect
to such Mortgage Loan.
 
     The 'Class IIPP-A-3 Prepayment Percentage' for any Distribution Date will
equal the product of (a) the Class IIPP-A-3 Percentage and (b) the Step Down
Percentage.
 
     The 'Step Down Percentage' for any Distribution Date will be the percentage
indicated below:

of the Group III Loans (exclusive of the portion thereof attributable to the
Class III-P Principal Distribution Amount), (ii) the Class III-A-3 Prepayment
Percentage of the Principal Prepayment Amount for the Group III Loans (exclusive

and Certificate Group, will be distributed as principal of the related Class or
Classes of Subordinate Certificates. Except as provided in the following
paragraph, each Class of Subordinate Certificates in a Certificate Group will be
entitled to receive its pro rata share (based upon its respective Class
Principal Balance) of such Subordinate Principal Distribution Amount, in each
case to the extent of the amount available from Available Funds for the related
Loan Group (which, in the case of the Group C-B Certificates, is the remaining
Available Funds for the Group I and Group II Loans) for distribution of
principal of such Class. Distributions of principal of the Subordinate
Certificates of a Certificate Group will be made on each Distribution Date
sequentially to the Classes of Subordinate Certificates in the order of their
numerical Class designation (beginning with the Class with the lowest numerical
Class designation) until each such Class of Subordinate Certificates has
received its respective pro rata share of the Subordinate Principal Distribution
Amount for such Certificate Group for such Distribution Date.
 
     With respect to each Class of Subordinate Certificates in a specified
Certificate Group, if on any Distribution Date the related Subordination Level
of such Class is less than such percentage as of the Closing Date, no
distributions of Payoffs and Curtailments with respect to the related Loan Group
or Loan Groups, in the case of the Group C-B Certificates, will be made to any
Class or Classes of Subordinate Certificates in the related Certificate Group
junior to such Class (the 'Restricted Classes') and the amount otherwise
distributable to the Restricted Classes in respect of such Payoffs and
Curtailments will be allocated among the remaining Classes of Subordinate
Certificates in such Certificate Group, pro rata, based upon their respective
Class Principal Balances.
 
     The 'Subordination Level' on any Distribution Date with respect to any
Class of Subordinate Certificates is the percentage obtained by dividing the sum
of the Class Principal Balances of all Classes of Certificates in the related
Certificate Group which are subordinate in right of payment to such Class by the
sum of the Class Principal Balances of all Classes of Certificates in the
related Certificate Group, in each case immediately prior to such Distribution
Date.
 
     The 'Subordinate Principal Distribution Amount' for any Distribution Date
and the Group C-B Certificates will equal (A) the sum of (i) the Subordinate
Percentage for the Group I Certificates of the Principal Payment Amount for the
Group I Loans, (ii) the Subordinate Percentage for the Group II Certificates of
the Principal Payment Amount for the Group II Loans (exclusive of the portion
thereof attributable to the Class II-P Principal Distribution Amount), (iii) the
Subordinate Prepayment Percentage for the Group I Certificates of the Principal
Prepayment Amount for the Group I Loans, (iv) the Subordinate Prepayment
Percentage for the Group II Certificates of the Principal Prepayment Amount for
the Group II Loans (exclusive of the portion thereof attributable to the Class
II-P Principal Distribution Amount) and (v) the Subordinate Liquidation Amount
for the Group I and Group II Loans less (B) the sum of (x) the Class PO Deferred
Amounts required to be paid to the Class II-P Certificates on such Distribution
Date, (y) in the event that the Class Principal Balance of either the Group I or
Group II Senior Certificates has been reduced to zero, principal paid from
Available Funds of the Loan Group related to such Certificate Group to the other
Certificate Group as described in ' -- Cross-Collateralization' herein and (z)
the amounts in respect of principal paid from Available Funds of any
Overcollateralized Group to any Undercollateralized Group, as described in
' -- Cross-Collateralization' herein.
 
     The 'Subordinate Principal Distribution Amount' for any Distribution Date
and the Group III-B Certificates will equal (A) the sum of (i) the Subordinate
Percentage for the Group III Certificates of the Principal Payment Amount for
the Group III Loans (exclusive of the portion thereof attributed to the Class
III-P Principal Distribution Amount), (ii) the Subordinate Prepayment Percentage
for the Group III Certificates of the Principal Prepayment Amount for the Group
III Loans (exclusive of the portion thereof attributable to the Class III-P
Principal Distribution Amount), and (iii) the Subordinate Liquidation Amount for
the Group III Loans less (B) the Class PO Deferred Amounts required to be paid
to the Class III-P Certificates on such Distribution Date.
 
     Any reduction to a Subordinate Principal Distribution Amount described
above shall first offset amounts in respect of the related Principal Payment
Amounts, second the related Subordinate Liquidation Amounts and then the related
Principal Prepayment Amounts.
 
     The 'Subordinate Liquidation Amount' for a Loan Group will equal the
excess, if any, of the aggregate Liquidation Principal of all Mortgage Loans in
such Loan Group which became Liquidated Mortgage Loans during the calendar month
preceding the month of such Distribution Date over the sum of the related Senior
Liquidation Amount for such Distribution Date.

     Class II-P Distribution Amount. On each Distribution Date, the Class II-P
Certificates will receive a portion of the Available Funds for the Group II
Loans attributable to principal received on or in respect of any Group II Loan
with a Net Rate of less than 6.50% per annum (a 'Class II-P Mortgage Loan'),
equal to the amount of such principal so attributable multiplied by a fraction,
the numerator of which is 6.50% minus the Net Rate on such Class II-P Mortgage
Loan and the denominator of which is 6.50% (the 'Class II-P Fraction'). In
addition, on each Distribution Date for so long as any of the Group C-B
Certificates remains outstanding, the Class II-P Certificates will also be
allocated principal, to the extent of amounts available to pay the related
Subordinate Principal Distribution Amount (without regard to Clause (B) of such
definition) on such Distribution Date, in an amount generally equal to the
Class PO Deferred Amounts for such Certificate Group not previously reimbursed;
provided, that such payments in respect of Class PO Deferred Amounts shall not
cause a further reduction of the outstanding Class II-P Principal Balance. The
aggregage of the amounts payable to the Class II-P Certificates described in
this paragraph are referred to herein as the 'Class II-P Principal Distribution
Amount.'
 
     Class III-P Principal Distribution Amount. On each Distribution Date, the
Class III-P Certificates will receive a portion of the Available Funds for the
Group III Loans attributable to principal received on or in respect of any Group
III Loan with a Net Rate of less than 6.75% per annum (a 'Class III-P Mortgage
Loan'), equal to the amount of such principal so attributable multiplied by a
fraction, the numerator of which is 6.75% minus the Net Rate on such Class III-P
Mortgage Loan and the denominator of which is 6.75% (the 'Class III-P
Fraction'). In addition, on each Distribution Date for so long as any of the
Group III-B Certificates remains outstanding, the Class III-P Certificates will
also be allocated principal, to the extent of amounts available to pay the
related Subordinate Principal Distribution Amount (without regard to clause (B)
of such definition) on such Distribution Date, in an amount generally equal to
the Class PO Deferred Amounts for such Certificate Group not previously
reimbursed; provided, that such payments in respect of Class PO Deferred Amounts
shall not cause a further reduction of the outstanding Class III-P Principal
Balance. The aggregate of the amounts payable to the Class III-P Certificates
described in this paragraph are referred to herein as the 'Class III-P Principal
Distribution Amount.'
 
     The Class II-P Mortgage Loans and Class III-P Mortgage Loans are
collectively referred to herein as the 'Class P Mortgage Loans.'
 
     Residual Certificates. The Class A-R Certificates will remain outstanding
for so long as the Trust Fund shall exist, whether or not they are receiving
current distributions of principal or interest. In addition to distributions of
interest and principal as described above, on each Distribution Date the holders
of the Class A-R Certificates will be entitled to receive Available Funds for
any Loan Group remaining after payment of interest and principal on the Senior
Certificates, Class PO Deferred Amounts on the Class P Certificates, if any, and
interest and principal on the Subordinate Certificates for such Distribution
Date, as described above. It is not anticipated that there will be any
significant amounts remaining for any such distribution.
 
ALLOCATION OF LOSSES
 
     On each Distribution Date, the applicable Class P Fraction of any Realized
Loss, including any Excess Loss, on a Class P Mortgage Loan in a Loan Group will
be allocated to the related Class P Certificates until the Class Principal
Balance thereof is reduced to zero. The amount of any such Realized Loss, other
than an Excess Loss, allocated on or prior to the Senior Credit Support
Depletion Date for a Certificate Group will be treated as a Class PO Deferred
Amount for such Certificate Group. To the extent funds are available on such
Distribution Date or on any future Distribution Date from amounts that would
otherwise be allocable to the Subordinate Principal Distribution Amount for such
Certificate Group, Class PO Deferred Amounts for such Certificate Group will be
paid on the related Class P Certificates prior to distributions on the
Subordinate Certificates for such Certificate Group. See ' -- Priority of
Distributions Among Certificates.' Any distribution in respect of unpaid Class
PO Deferred Amounts will not further reduce the Class Principal Balance of the
Class P Certificates. The Class PO Deferred Amounts will not bear interest. The
Class Principal Balance of the Class of Subordinate Certificates then
outstanding with the highest numerical Class designation for such Certificate
Group will be reduced by the amount of any payments in respect of Class PO
Deferred Amounts. After the Senior Credit Support Depletion Date for a
Certificate Group, no new Class PO Deferred Amounts will be created in respect
of the related Class P Certificates.
 
                                      S-38
 

<PAGE>

<PAGE>
     On each Distribution Date, any Realized Loss (other than the Class P
Fraction thereof, if applicable), other than any Excess Loss, experienced by a
Loan Group will be allocated first to the Subordinate Certificates for the
related Certificate Group, in decreasing order of their numerical Class
designations (beginning with the Class of Subordinate Certificates then
outstanding with the highest numerical Class designation), in each case until
the Class Principal Balance of the respective Class of Certificates has been
reduced to zero, and then to the Senior Certificates for such Certificate Group
(other than the related Notional Amount and Class P Certificates, if any) pro
rata, based upon their respective Class Principal Balances.
 
     On each Distribution Date, Excess Losses (other than the Class P Fraction
thereof, if applicable) experienced by the Group I and Group II Loans will be
allocated pro rata among the Classes of Group I and Group II Certificates (other
than the related Class P Certificates, if any) based upon their respective Class
Principal Balances. On each Distribution Date, Excess Losses (other than the
Class P Fraction thereof, if applicable) experienced by the Group III Loans will
be allocated pro rata among the Classes of the Group III Certificates (other
than the related Notional Amount and Class P Certificates) based on their
respective Class Principal Balances.
 
     Because principal distributions are paid to certain Classes of Group II
Senior Certificates before other Classes of Senior Certificates for such
Certificate Group, holders of such Senior Certificates that are entitled to
receive principal later for such Certificate Group bear a greater risk of being
allocated Realized Losses on the Mortgage Loans than holders of Classes that are
entitled to receive principal earlier.
 
     Because principal distributions are paid to certain Classes of Group III
Senior Certificates before other Classes of Senior Certificates for such
Certificate Group, holders of such Senior Certificates that are entitled to
receive principal later for such Certificate Group bear a greater risk of being
allocated Realized Losses on the Mortgage Loans than holders of Classes that are
entitled to receive principal earlier.
 
     On each Distribution Date, if the aggregate Class Principal Balance of all
Group I and Group II Certificates exceeds the aggregate Stated Principal Balance
of the Group I and Group II Loans (after giving effect to distributions of
principal and the allocation of all losses to the Group I and Group II
Certificates on such Distribution Date), such excess will be deemed a principal
loss and will be allocated to the most junior Class of Group C-B Certificates
then outstanding.
 
     On each Distribution Date, if the aggregate Class Principal Balance of all
Group III Certificates exceeds the aggregate Stated Principal Balance of the
Group III Loans (after giving effect to distributions of principal and the
allocation of all losses to the Group III Certificates on such Distribution
Date), such excess will be deemed a principal loss and will be allocated to the
most junior Class of Group III-B Certificates then outstanding.
 
     Investors in the Group I Senior and Group II Senior Certificates should be
aware that because the Group C-B Certificates represent interests in both the
Group I and Group II Loans, the Class Principal Balances of the Group C-B
Certificates could be reduced to zero as a result of a disproportionate amount
of Realized Losses on the Mortgage Loans in one of such Loan Groups. Therefore,
notwithstanding that Realized Losses on the Mortgage Loans in one Loan Group may
only be allocated to the related Senior Certificates, other than Excess Losses,
the allocation to the Group C-B Certificates of Realized Losses on the Mortgage
Loans in the other Loan Group will increase the likelihood that losses may be
allocated to such Senior Certificates.
 
     In general, a 'Realized Loss' means, either (i) a Bankruptcy Loss or (ii)
with respect to a Liquidated Mortgage Loan, the amount by which the remaining
unpaid principal balance of the Mortgage Loan exceeds the amount of Liquidation
Proceeds applied to the principal balance of the related Mortgage Loan. 'Excess
Losses' are (i) Special Hazard Losses in excess of the applicable Special Hazard
Loss Coverage Amount, (ii) Bankruptcy Losses in excess of the applicable
Bankruptcy Loss Coverage Amount, and (iii) Fraud Losses in excess of the
applicable Fraud Loss Coverage Amount. 'Special Hazard Losses' are Realized
Losses in respect of Special Hazard Mortgage Loans. 'Bankruptcy Losses' are
losses that are incurred as a result of Debt Service Reductions and Deficient
Valuations. 'Fraud Losses' are Realized Losses sustained by reason of a default
arising from fraud, dishonesty or misrepresentation. See 'Credit
Enhancement -- Subordination of Certain Classes' herein.
 
     A 'Special Hazard Mortgage Loan' is a Liquidated Mortgage Loan as to which
the ability to recover the full amount due thereunder was substantially impaired
by a hazard not insured against under a standard hazard insurance policy of the
type described in the Prospectus under 'Description of Mortgage and Other
Insurance -- Hazard Insurance on the Loans.' See 'Credit
Enhancement -- Subordination of Certain Classes' herein.

CROSS-COLLATERALIZATION
 
CROSS-COLLATERALIZATION DUE TO RAPID PREPAYMENTS IN LOAN GROUP I OR LOAN GROUP
II
 
     On each Distribution Date prior to the occurrence of the reduction of the
aggregate Class Principal Balance of the Group C-B Certificates to zero, but
after the date on which the aggregate Class Principal Balance of the Group I
Senior or Group II Senior Certificates (other than the Class Principal Balance
of the Class II-P Certificates) has been reduced to zero, all principal on the
Mortgage Loans relating to such Senior Certificates that have been paid in full,
after distributions of principal to the Class P Certificates, if any, of such
Certificate Group will be paid to the Senior Certificates (other than the
related Class P Certificates, if any) of the other Certificate Group; provided,
however, that principal will not be distributed as described above if on such
Distribution Date (a) the Group C-B Percentage for such Distribution Date is
greater than or equal to 200% of the Group C-B Percentage as of the Closing Date
and (b) the average outstanding principal balance of the Group I and Group II
Loans delinquent 60 days or more over the last six months, as a percentage of
the related Group C-B Loan Group Component Balance, is less than 50%. If
principal from either the Group I or Group II Loans is distributed to the Senior
Certificates of the other Loan Group according to this paragraph, the Group C-B
Certificates will not receive such principal amount.
 
     The 'Group C-B Percentage' for any Distribution Date will equal the
aggregate Class Principal Balance of the Group C-B Certificates immediately
prior to such Distribution Date divided by the then outstanding aggregate Stated
Principal Balance of the Group I and Group II Loans as of the Due Date in the
month of such Distribution Date.
 
     The 'Group C-B Loan Group Component Balance' for the Group I or Group II
Loans at any time will equal the excess, if any, of the then outstanding
aggregate Stated Principal Balance of the Mortgage Loans in the applicable Loan
Group over the then outstanding aggregate Class Principal Balance of the Group I
Senior or Group II Senior Certificates, as applicable.
 
CROSS-COLLATERALIZATION DUE TO DISPROPORTIONATE REALIZED LOSSES IN LOAN GROUP I
OR LOAN GROUP II
 
     In addition, if on any Distribution Date the aggregate Class Principal
Balance of either the Group I Senior or Group II Senior Certificates (other than
the Class Principal Balance of the Class II-P Certificates) is greater than the
aggregate Stated Principal Balance of the Mortgage Loans in the related Loan
Group less the applicable Class P Fraction of each Class P Mortgage Loan, if
any, in such Loan Group (the 'Undercollateralized Group'), then (i) the portion
of the Available Funds in respect of principal on the Mortgage Loans in the
other Loan Group (the 'Overcollateralized Group') (after distributions of
principal to the Senior Certificates of the Overcollateralized Group) will be
distributed to the Senior Certificates of the Undercollateralized Group (other
than the related Class P Certificates, if any), until the aggregate Class
Principal Balance of such Senior Certificates of the Undercollateralized Group
equals the aggregate Stated Principal Balance of the Mortgage Loans in the
related Loan Group less the applicable Class P Fraction of each Class P Mortgage
Loan, if any, in such Loan Group and (ii) the Available Funds of the
Overcollateralized Group will be further reduced (after distributions of
interest to the Senior Certificates of the Overcollateralized Group) in an
amount equal to one month's interest on the amount by which the
Undercollateralized Group is undercollateralized at 6.50% per annum and such
amount will be added to the Available Funds of the Undercollateralized Group.
Consequently, the Group C-B Certificates will not receive any distributions of
principal until the Undercollateralized Group is no longer undercollateralized.
 
OPTIONAL TERMINATION
 
     The Depositor will have the right to repurchase all remaining Mortgage
Loans and REO Properties in the Trust Fund and thereby effect early retirement
of the Certificates, subject to the aggregate Stated Principal Balance of such
Mortgage Loans and REO Properties at the time of repurchase being less than 5%
of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date. In the event the Depositor exercises such option, the purchase
price distributed with respect to each Certificate will be 100% of its then
outstanding principal balance plus any Class PO Deferred Amounts in the case of
the Class P Certificates and, in the case of an interest-bearing Certificate,
any unpaid accrued interest on such Class Principal Balance or Notional Amount,
as applicable, at the applicable Pass-Through Rate (in each case subject to
reduction as provided in the Agreement for amounts owed to the Servicers or if
the purchase price is based in part on the
 
                                      S-40
 

<PAGE>

<PAGE>
appraised value of any REO Properties and such appraised value is less than the
Stated Principal Balance of the related Mortgage Loans). Distributions on the
Certificates in respect of any such optional termination will first be paid to
the Senior Certificates and then to the Subordinate Certificates. The proceeds
from any such distribution may not be sufficient to distribute the full amount
to which each Class of Certificates is entitled if the purchase price is based
in part on the appraised value of any REO Property and such appraised value is
less than the Stated Principal Balance of the related Mortgage Loan or amounts
are owed to the Servicers.
 
THE TRUSTEE
 
     The First National Bank of Chicago will be the Trustee under the Agreement.
The Depositor and each Servicer and Seller may maintain other banking
relationships in the ordinary course of business with The First National Bank of
Chicago. Offered Certificates may be surrendered at the Corporate Trust Office
of the Trustee located at First Chicago Trust Company of New York, 14 Wall
Street, Eighth Floor, New York, New York 10005, Attention: Corporate Trust
Administration or at such other addresses as the Trustee may designate from time
to time.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R CERTIFICATES
 
     The Class A-R Certificates will be subject to the restrictions on transfer
described in the Prospectus under 'Certain Federal Income Tax
Consequences -- REMICs -- Taxation of Owners of REMIC Residual
Certificates -- Tax and Restrictions on Transfers of REMIC Residual Certificates
to Certain Organizations'. The Agreement provides that the Class A-R
Certificates (in addition to certain other Classes of Certificates) may not be
acquired by an ERISA Plan. See 'ERISA Considerations' herein. Each Class A-R
Certificate will contain a legend describing the foregoing restrictions.
 
                 YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS
 
GENERAL
 
     The effective yields to the holders of the interest-bearing Certificates
will be lower than the yields otherwise produced by the applicable rate at which
interest is passed through to such holders and the purchase price of such
Certificates because monthly distributions will not be payable to such holders
of the Group I and Group II Certificates until the 19th day and to such holders
of the Group III Certificates until the 25th day (or, if either such day is not
a business day, the following business day) of the month following the month in
which interest accrues on the Mortgage Loans (without any additional
distribution of interest or earnings thereon in respect of such delay).
 
     Delinquencies on the Mortgage Loans in a Loan Group which are not advanced
by or on behalf of the related Servicer (because amounts, if advanced, would be
nonrecoverable), will adversely affect the yield on the Certificates of the
related Certificate Group. Because of the priority of distributions, shortfalls
resulting from delinquencies not so advanced will be borne first by the
Subordinate Certificates of such Certificate Group (which, in the case of the
Group I and Group II Certificates, are the Group C-B Certificates) in the
reverse order of their numerical Class designations, and then by the related
Senior Certificates. If, as a result of such shortfalls, the aggregate of the
Class Principal Balances of the Group I and Group II Certificates exceeds the
aggregate Stated Principal Balances of the Group I and Group II Loans, the Class
Principal Balance of the Class of Group C-B Certificates then outstanding with
the highest numerical Class designation will be reduced by the amount of such
excess. If, as a result of such shortfalls, the aggregate of the Class Principal
Balances of the Group III Certificates exceeds the aggregate Stated Principal
Balances of the Group III Loans, the Class Principal Balance of the Class of
Group III-B Certificates then outstanding with the highest numerical Class
designation will be reduced by the amount of such excess.
 
     The likelihood that Mortgage Loans will become delinquent and the rate of
any subsequent foreclosures may be affected by a number of factors related to
the Mortgagor's personal circumstances, including, for example, unemployment or
change in employment (or in the case of self-employed Mortgagors relying on
commission income, fluctuations in income), marital separation and a Mortgagor's
equity in the related Mortgaged Property. In addition, delinquency and
foreclosure experience may be sensitive to adverse economic conditions, either
nationally or regionally, may exhibit seasonal variations and may be influenced
by the level of interest rates as they affect real estate sales activity.
Regional economic conditions (including declining real
 
                                      S-41
 

<PAGE>

<PAGE>
estate values) may particularly affect delinquency and foreclosure experience on
the Mortgage Loans to the extent that the related Mortgaged Properties are
concentrated in certain geographic areas.
 
     Net Interest Shortfalls will adversely affect the yields on the Offered
Certificates of the Certificate Group to which they relate. In addition,
although all losses initially will be borne by the Subordinate Certificates of
the related Certificate Group in decreasing order of their numerical Class
designations (either directly or through distributions in respect of Class PO
Deferred Amounts on the related Class P Certificates, if any), Excess Losses on
the Group I and Group II Loans will be borne by all Classes of the Group I and
Group II Certificates and Excess Losses on the Group III Loans will be borne by
all Classes of the Group III Certificates, in each case on a pro rata basis.
Moreover, since the Subordinate Principal Distribution Amount for a Certificate
Group for each Distribution Date will be reduced by the amount of any
distributions on such Distribution Date in respect of related Class PO Deferred
Amounts and by the implementation of the cross-collateralization mechanics
described above under 'Description of the Certificates -- 
Cross-Collateralization' herein, the amount distributable as principal on each
such Distribution Date to each Class of Subordinate Certificates in such
Certificate Group then entitled to a distribution of principal will be less than
it otherwise would be in the absence of such Class PO Deferred Amounts and
cross-collateralization feature. As a result, the yields on the Offered
Certificates will depend on the rate and timing of Realized Losses, including
Excess Losses. Excess Losses could occur at a time when one or more Classes of
Subordinate Certificates are still outstanding and otherwise available to absorb
other types of Realized Losses.
 
PREPAYMENT CONSIDERATIONS AND RISKS
 
     Distributions to the Group I Senior and Group II Senior Certificates relate
to payments on the Group I and Group II Loans, respectively, except in the
limited circumstances described herein under 'Description of the
Certificates -- Cross-Collateralization.' Distributions to the Group III
Certificates relate to payments on the Group III Loans. Distributions to the
Group C-B Certificates relate to payments on the Group I and Group II Loans. The
rate of principal payments on the Offered Certificates, the aggregate amount of
distributions on the Offered Certificates and the yields to maturity of the
Offered Certificates will be related to the rate and timing of payments of
principal on the Mortgage Loans in the related Loan Group or Loan Groups, as
applicable. The rate of principal payments on the Mortgage Loans will in turn be
affected by the amortization schedules of the Mortgage Loans and by the rate of
principal prepayments (including for this purpose prepayments resulting from
refinancing, liquidations of the Mortgage Loans due to defaults, casualties,
condemnations and repurchases by the related Seller or related Servicer). The
majority of the Group III Loans may be prepaid by the Mortgagors at any time
without a prepayment penalty. The Group I and Group II Loans and a portion of
the Group III Loans impose penalties for certain prepayments during a specified
period for each such Mortgage Loan occurring during the first one to five years
after origination. Due to such prepayment penalties on such Mortgage Loans, the
rate of prepayment may be slower than otherwise would be the case, particularly
in a declining interest rate environment. The Mortgage Loans are subject to the
'due-on-sale' provisions included therein. However, the related Servicer may
choose not to accelerate a Mortgage Loan upon the conveyance of the related
Mortgaged Property if such Servicer would make a similar decision with respect
to a comparable mortgage loan held for its own account. See 'The Mortgage Pool'
herein.
 
     Prepayments, liquidations and purchases of the Mortgage Loans in a Loan
Group (including any optional purchase by the related Servicer of a defaulted
Mortgage Loan in such Loan Group and any optional repurchase of the remaining
Mortgage Loans in connection with the termination of the Trust Fund, in each
case as described herein) will result in distributions on the Offered
Certificates for the related Certificate Group of principal amounts which would
otherwise be distributed over the remaining terms of the Mortgage Loans. Since
the rate of payment of principal on the Mortgage Loans will depend on future
events and a variety of other factors, no assurance can be given as to such rate
or the rate of principal prepayments. The extent to which the yield to maturity
of a Class of Offered Certificates may vary from the anticipated yield will
depend upon the degree to which such Offered Certificate is purchased at a
discount or premium, and the degree to which the timing of payments thereon is
sensitive to prepayments, liquidations and purchases of the Mortgage Loans in
the related Loan Group or Loan Groups. Further, an investor should consider the
risk that, in the case of the Class P Certificates and any other Offered
Certificate purchased at a discount, a slower than anticipated rate of principal
payments (including prepayments) on the Mortgage Loans in the related Loan Group
or Loan Groups, as applicable, could result in an actual yield to such investor
that is lower than the anticipated yield and, in the case
 
                                      S-42
 

<PAGE>

<PAGE>
of the Notional Amount Certificates and any other Offered Certificate purchased
at a premium, a faster than anticipated rate of principal payments on the
Mortgage Loans in the related Loan Group or Loan Groups, as applicable, could
result in an actual yield to such investor that is lower than the anticipated
yield. Investors in the Notional Amount Certificates should carefully consider
the risk that a rapid rate of principal prepayments on the Mortgage Loans in the
related Loan Group could result in the failure of such investors to recover
their initial investments.
 
     The rate of principal payments (including prepayments) on pools of mortgage
loans may vary significantly over time and may be influenced by a variety of
economic, geographic, social and other factors, including changes in mortgagors'
housing needs, job transfers, unemployment, mortgagors' net equity in the
mortgaged properties and servicing decisions (including the Servicer's decision
whether or not to exercise its rights under any 'due-on-sale' clause). In
general, if prevailing interest rates were to fall significantly below the
Mortgage Rates on the Mortgage Loans, the Mortgage Loans could be subject to
higher prepayment rates than if prevailing interest rates were to remain at or
above the Mortgage Rates on the Mortgage Loans. Conversely, if prevailing
interest rates were to rise significantly, the rate of prepayments on the
Mortgage Loans would generally be expected to decrease. No assurances can be
given as to the rate of prepayments on the Mortgage Loans in stable or changing
interest rate environments.
 
     As described herein under 'Description of the Certificates -- Distributions
of Principal,' the applicable Senior Prepayment Percentage of the Principal
Prepayment Amount for a Loan Group (exclusive of the portion thereof
attributable to the applicable Class P Principal Distribution Amount, if any)
will be initially distributed to the Senior Certificates of the related
Certificate Group (other than the related Class P Certificates, if any, and the
Class IIPP-A-3 and Class III-A-3 Certificates, if applicable). This may result
in all (or a disproportionate percentage) of such principal prepayments being
distributed to holders of the Senior Certificates (other than the related Class
P Certificates, if any, and the Class IIPP-A-3 and Class III-A-3 Certificates,
if applicable) in a Certificate Group and none (or less than their pro rata
share) of such principal prepayments being distributed to holders of the related
Subordinate Certificates during the periods of time described in the definition
of 'Senior Prepayment Percentage.' The Class IIPP-A-3 and Class III-A-3
Certificates generally will not receive any distributions of principal for the
first five years after the Closing Date.
 
     The timing of changes in the rate of prepayments on the Mortgage Loans may
significantly affect an investor's actual yield to maturity, even if the average
rate of principal payments is consistent with an investor's expectation. In
general, the earlier a prepayment of principal on the Mortgage Loans, the
greater the effect on an investor's yield to maturity. The effect on an
investor's yield as a result of principal payments occurring at a rate higher
(or lower) than the rate anticipated by the investor during the period
immediately following the issuance of the Offered Certificates may not be offset
by a subsequent like decrease (or increase) in the rate of principal payments.

(ii) the Mortgage Loans prepay at the specified constant Prepayment Assumption
described below for the related Class of Certificates, (iii) no defaults in the

Date and are computed prior to giving effect to prepayments received on the last
day of the prior month, (v) prepayments are allocated as described herein
without giving effect to loss and delinquency tests, (vi) there are no Net
Interest Shortfalls and prepayments represent prepayments in full of the
Mortgage Loans and are received on the last day of each month, commencing in the

Mortgage Loan has been calculated based on the assumed mortgage loan
characteristics described in item (i) above such that the Mortgage Loans will
amortize in amounts sufficient to repay the principal balances of such assumed
mortgage loans by its respective amortizing remaining term, (viii) the initial

Certificates is as set forth under 'Summary Information' herein, (ix) interest
accrues on each interest-bearing Class of Certificates at the applicable
interest rate set forth or described under 'Summary Information' herein, (x)
distributions in respect of a Certificate Group are received in cash on the 19th
day, in the case of the Group I and Group II Certificates, and the 25th day, in
the case of the Group III Certificates, of each month commencing in the calendar
month following the Closing Date, (xi) the closing date of the sale of the
Offered Certificates is April 30, 1999, (xii) none of the Sellers are required
to repurchase or substitute for any Mortgage Loan, (xiii) the Depositor does not
exercise any option to repurchase the Mortgage Loans described herein under
'Description of the Certificates -- Optional Termination' and (xiv) no Class of
Subordinate Certificates becomes a Restricted Class. While it is assumed that
each Mortgage Loan prepays at the specified constant Prepayment Assumption, this
is not likely to be the case. Moreover, discrepancies will exist between the
characteristics of the actual Mortgage Loans which will be delivered to the
Trustee and the characteristics of the Mortgage Loans assumed in preparing the
tables herein.
 
     Prepayments of mortgage loans commonly are measured relative to a
prepayment standard or model. The two prepayment models used in this Prospectus
Supplement (each, a 'Prepayment Assumption') represent an assumed rate of
prepayment each month relative to the then outstanding principal balance of a
pool of mortgage loans. For the Group I and Group II Certificates, a 100%
Prepayment Assumption is a constant prepayment rate ('CPR') of 4% per annum of
the then outstanding principal balance of the Group I and Group II Loans in the
first month of the life of the mortgage loans and an additional 0.6666666666%
(precisely 2/3) per annum in each month thereafter until the eighteenth month.
Beginning in the nineteenth month and in each month thereafter during the life
of the mortgage loans, a 100% Prepayment Assumption assumes a CPR of 16% per
annum each month. For the Group III Certificates, a 100% Prepayment Assumption
assumes a CPR of 6.0% per annum of the then outstanding principal balance of the
Group III Loans in the first month of the life of the mortgage loans and an
additional 1.27272727% (precisely 14/11) per annum in each month thereafter
until the eleventh month. Beginning in the twelfth month and in each month
thereafter during the life of the mortgage loans, a 100% Prepayment Assumption
assumes a CPR of 20% per annum each month. As used in the table below, a 50%
Prepayment Assumption assumes prepayment rates equal to 50% of the related
Prepayment Assumption. Correspondingly, a 200% Prepayment Assumption assumes
prepayment rates equal to 200% of the related Prepayment Assumption, and so
forth. The Prepayment Assumption does not purport to be a historical description
of prepayment experience or a prediction of the anticipated rate of prepayment
of any pool of mortgage loans, including the Mortgage Loans.

     The sensitivity tables below indicate the sensitivity of the pre-tax
corporate bond equivalent yields to maturity of certain Classes of Certificates
to various constant Prepayment Assumptions. The yields set forth in the tables
were calculated by determining the monthly discount rates that, when applied to
the assumed stream of cash flows to be paid on the applicable Class of
Certificates, would cause the discounted present value of such assumed stream of
cash flows to equal the assumed purchase price of such Classes and converting
such monthly rates to corporate bond equivalent rates. Such calculations do not
take into account variations that may occur in the interest rates at which
investors may be able to reinvest funds received by them as distributions on
certain Classes of Certificates and consequently do not purport to reflect the
return on any investment in any such Class of Certificates when such
reinvestment rates are considered.
 
SENSITIVITY OF THE CLASS P CERTIFICATES
 
     THE CLASS II-P AND CLASS III-P CERTIFICATES WILL BE 'PRINCIPAL ONLY'
CERTIFICATES AND WILL NOT BEAR INTEREST. AS INDICATED IN THE TABLE BELOW, A LOW
RATE OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) OF THE CLASS P MORTGAGE LOANS
IN THE RELATED LOAN GROUP WILL HAVE A NEGATIVE EFFECT ON THE YIELD TO INVESTORS
IN THE RELATED CLASS P CERTIFICATES.
 
     As described above under 'Description of the Certificates -- Distributions
of Principal,' the Class P Principal Distribution Amount for a Class of Class P
Certificates is calculated by reference to the principal payments (including
prepayments) on the Class P Mortgage Loans in the related Loan Group. The Class
P Mortgage Loans in the related Loan Group will have lower Net Rates (and lower
Mortgage Rates) than the other Mortgage Loans in such Loan Group. In general,
mortgage loans with higher mortgage rates tend to prepay at higher rates than
mortgage loans with relatively lower mortgage rates in response to a given
reduction in market interest rates. As a result, the Class P Mortgage Loans in
the related Loan Group may prepay at lower rates, thereby reducing the rate of
payment of principal and the resulting yield of the related Class P
Certificates.
 
     The information set forth in the following table has been prepared on the
basis of the Structuring Assumptions and on the assumption that the aggregate
purchase price of the Class P Certificates (expressed as a percentage of initial
Class Principal Balance) is as follows:

     It is highly unlikely that all of the Mortgage Loans of a specific Loan
Group will have the characteristics assumed or that the Mortgage Loans of a
specific Loan Group will prepay at any constant rate until maturity or that all
of the Mortgage Loans of a specific Loan Group will prepay at the same rate or
time. As a result of these factors, the pre-tax yield on the Class P
Certificates is likely to differ from those shown in the table above, even if
all of the applicable Mortgage Loans prepay at the indicated percentages of the
applicable Prepayment Assumption. No representation is made as to the actual
rate of principal payments on the Class P Mortgage Loans of a specific Loan
Group for any period or over the life of the Certificates or as to the yield on
the Class P Certificates. Investors must make their own decisions as to the
appropriate prepayment assumptions to be used in deciding whether to purchase a
Class of Class P Certificates.

     AS INDICATED IN THE TABLE BELOW, THE YIELDS TO INVESTORS ON THE CLASS III-X
CERTIFICATES WILL BE SENSITIVE TO THE RATE OF PRINCIPAL PAYMENTS (INCLUDING

GENERALLY CAN BE PREPAID AT ANY TIME. ON THE BASIS OF THE ASSUMPTIONS DESCRIBED
BELOW, THE YIELD TO MATURITY ON THE CLASS III-X AND CLASS III-A-6 CERTIFICATES
WOULD BE APPROXIMATELY 0% IF PREPAYMENTS WERE TO OCCUR AT A CONSTANT RATE OF
APPROXIMATELY 203% AND 151% RESPECTIVELY, OF THE APPLICABLE PREPAYMENT
ASSUMPTION. IF THE ACTUAL PREPAYMENT RATE OF THE GROUP III LOANS WERE TO EXCEED
THE APPLICABLE LEVEL FOR AS LITTLE AS ONE MONTH WHILE EQUALING SUCH LEVEL FOR
THE REMAINING MONTHS, THE INVESTORS IN THE NOTIONAL AMOUNT CERTIFICATES WOULD
NOT FULLY RECOUP THEIR INITIAL INVESTMENTS.
 
     As described above under 'Description of the Certificates -- Distribution
of Interest,' the Notional Amount of the Class III-X Certificates in effect from
time to time is calculated by reference to the Net Rates of the Group III
Premium Rate Mortgage Loans. In general, mortgage loans with higher mortgage
rates tend to prepay at higher rates than mortgage loans with relatively lower
mortgage rates in response to a given change in market interest rates. As a
result, the Group III Premium Rate Mortgage Loans may prepay at higher rates,
thereby reducing the Notional Amount of the Class III-X Certificates.
 
     The information set forth in the following table has been prepared on the
basis of the Structuring Assumptions (which assume no Realized Losses), and on
the assumption that the purchase prices (expressed as a percentage of initial
Notional Amount) of the Notional Amount Certificates are as follows:

     It is highly unlikely that all of the Mortgage Loans will have the
characteristics assumed or that the Group III Loans will prepay at any constant
rate until maturity or that all of such Mortgage Loans will prepay at the same
rate or time. As a result of these factors, the pre-tax yields on the Notional
Amount Certificates are likely to differ from those shown in the table above,
even if all of the Group III Loans prepay at the indicated percentages of the
applicable Prepayment Assumption. No representation is made as to the actual
rate of principal payments on the Mortgage Loans for any period or over the
lives of the Notional Amount Certificates or as to the yield on the Notional
Amount Certificates. Investors must make their own decisions as to the
appropriate prepayment assumptions to be used in deciding whether to purchase
the Notional Amount Certificates.
 
WEIGHTED AVERAGE LIVES OF THE OFFERED CERTIFICATES
 
     The weighted average life of any Class of Certificates is determined by (a)
multiplying the amount of the reduction, if any, of the Class Principal Balance
of such Certificate on each Distribution Date by the number of years from the
date of issuance to such Distribution Date, (b) summing the results and (c)
dividing the sum by the aggregate amount of the reductions in Class Principal
Balance of such Class referred to in clause (a).
 
     For a discussion of the factors which may influence the rate of payments
(including prepayments) of the Mortgage Loans, see ' -- Prepayment
Considerations and Risks' herein and 'Yield, Prepayment and Maturity
Considerations' in the Prospectus.
 
                                      S-46
 

<PAGE>

<PAGE>
     In general, the weighted average lives of the Offered Certificates will be
shortened if the level of prepayments of principal of the Mortgage Loans in the
related Loan Group or Loan Groups, as applicable, increases. However, the
weighted average lives of the Offered Certificates will depend upon a variety of
other factors, including the timing of changes in such rate of principal
payments and the priority sequence of distributions of principal of the Classes
of Certificates. See 'Description of the Certificates -- Distribution of
Principal' herein.
 
     The interaction of the foregoing factors may have different effects on
various Classes of Offered Certificates and the effects on any Class may vary at
different times during the life of such Class. Accordingly, no assurance can be
given as to the weighted average life of any Class of Offered Certificates.
Further, to the extent the prices of the Offered Certificates represent
discounts or premiums to their respective original Class Principal Balances,
variability in the weighted average lives of such Classes of Offered
Certificates will result in variability in the related yields to maturity. For
an example of how the weighted average lives of the Classes of Offered
Certificates may be affected at various constant Prepayment Assumptions, see
' -- Decrement Tables' below.
 
DECREMENT TABLES
     The following tables indicate the percentages of the initial Class
Principal Balances of the Classes of Offered Certificates (other than the
Notional Amount Certificates) that would be outstanding after each of the dates
shown at various Prepayment Assumptions and the corresponding weighted average
lives of such Classes. The tables have been prepared on the basis of the
Structuring Assumptions. It is not likely that (i) all of the Mortgage Loans
will have the characteristics assumed, (ii) all of the Mortgage Loans will
prepay at the applicable Prepayment Assumption specified in the tables or at any
constant rate or (iii) all of the Mortgage Loans will prepay at the same rate.
Moreover, the diverse remaining terms to maturity of the Mortgage Loans could
produce slower or faster principal distributions than indicated in the tables at
the applicable Prepayment Assumptions, even if the weighted average remaining
term to maturity of the Mortgage Loans is consistent with the remaining terms to
maturity of the Mortgage Loan specified in the Structuring Assumptions.

LAST SCHEDULED DISTRIBUTION DATE
 
     The Last Scheduled Distribution Date for the Group I Certificates is the
Distribution Date in May 2029, which is the Distribution Date in the month after
the scheduled maturity date for the latest maturing Group I Loan. The Last
Scheduled Distribution Date for the Group II Certificates (other than the Group
C-B Certificates) is the Distribution Date in May 2029, which is the
Distribution Date in the month after the scheduled maturity date for the latest
maturing Group II Loan. The Last Scheduled Distribution Date for the Group III
Certificates is the Distribution Date in July 2029, which is the Distribution
Date in the month after the scheduled maturity date for the latest maturing
Group III Loan. The Last Scheduled Distribution Date for the Group C-B
Certificates is the Distribution Date in May 2029, which is the Distribution
Date in the month after the scheduled maturity date for the latest maturing
Group I or Group II Loan. Since the rate of distributions in reduction of the
Class Principal Balance or Notional Amount of each Class of Offered Certificates
will depend on the rate of payment (including prepayments) of the related
Mortgage Loans, the Class Principal Balance or Notional Amount of any such Class
could be reduced to zero significantly earlier or later than the Last Scheduled
Distribution Date. The rate of payments on the Mortgage Loans will depend on
their particular characteristics, as well as on prevailing interest rates from
time to time and other economic factors, and no assurance can be given as to the
actual payment experience of the Mortgage Loans. See ' -- Prepayment
Considerations and Risks' and ' -- Weighted Average Lives of the Offered
Certificates' herein and 'Yield, Prepayment and Maturity Considerations' in the
Prospectus.
 
THE SUBORDINATE CERTIFICATES
 
     The weighted average lives of, and the yields to maturity on, the Group C-B
and Group III-B Certificates, in increasing order of their numerical Class
designations, will be progressively more sensitive to the rate and timing of
mortgagor defaults and the severity of ensuing losses on the Mortgage Loans in
the related Loan Group (which in the case of the Group C-B Certificates,
includes both the Group I and Group II Loans). If the actual rate and severity
of losses on the Mortgage Loans in the related Loan Group or Loan Groups, as
applicable, are higher than those assumed by a holder of a Subordinate
Certificate, the actual yield to maturity of such Certificate may be lower than
the yield expected by such holder based on such assumption. The timing of losses
on the Mortgage Loans in a Loan Group will also affect an investor's actual
yield to maturity, even if the rate of defaults and severity of losses over the
life of the Mortgage Loans are consistent with an investor's expectations. In
general, the earlier a loss occurs, the greater the effect on an investor's
yield to maturity. Realized Losses on the Mortgage Loans in the related Loan
Group (which, in the case of the Group C-B Certificates, are the Group I and
Group II Loans) will reduce the Class Principal Balance of the applicable Class
of Subordinate Certificates in the related Certificate Group to the extent of
any losses allocated thereto (as described under 'Description of the
Certificates -- Allocation of Losses'), without the receipt of cash attributable
to such reduction. In addition, shortfalls in cash available for distributions
on the Subordinate Certificates of a Certificate Group will result in a
reduction in the Class Principal Balance of the Class of Subordinate
Certificates then outstanding with the highest numerical Class designation after
giving effect to all distributions and allocations of losses, as described
herein under 'Description of the Certificates -- Allocation of Losses.' As a
result of such reductions, less interest will accrue on such Class or Classes of
Subordinate Certificates than otherwise would be the case. The yield to maturity
of the Subordinate Certificates of a Certificate Group will also be affected by
the disproportionate allocation of the related Principal Prepayment Amount to
the Senior Certificates of such Certificate Group, related Net Interest
Shortfalls and other cash shortfalls in Available Funds for the related Loan
Group or Loan Groups and distributions of funds to the holders of the applicable
Class P Certificates, if any, of amounts otherwise available for distributions
on the related Subordinate Certificates to the extent of reimbursement for
related Class PO Deferred Amounts. See 'Description of the
Certificates -- Allocation of Losses' and ' -- Cross-Collateralization' herein.
 
     If on any Distribution Date the related Subordination Level for any Class
of Subordinate Certificates is less than such percentage as of the Closing Date,
all Payoffs and Curtailments with respect to the related Loan Group or Loan
Groups, in the case of the Group C-B Certificates, available for distribution on
the Subordinate Certificates of such Certificate Group will be allocated solely
to such Class and all other Classes of Subordinate Certificates in such
Certificate Group with lower numerical Class designations, thereby accelerating
the amortization thereof relative to that of the Restricted Classes and reducing
the weighted average lives of such Classes of Subordinate Certificates receiving
such distributions. Accelerating the amortization of the Classes of

Subordinate Certificates with lower numerical Class designations relative to the
other Classes of Subordinate Certificates in such Certificate Group is intended
to preserve the availability of the subordination provided by such other
Classes.
 
ADDITIONAL INFORMATION
 
     The Depositor intends to file certain additional yield tables and other
computational materials with respect to one or more Classes of Offered
Certificates with the Commission in a report on Form 8-K. Such tables and
materials were prepared by the Underwriter at the request of certain prospective
investors, based on assumptions provided by, and satisfying the special
requirements of, such prospective investors. Such tables and assumptions may be
based on assumptions that differ from the Structuring Assumptions. Accordingly,
such tables and other materials may not be relevant to or appropriate for
investors other than those specifically requesting them.
 
                               CREDIT ENHANCEMENT
 
SUBORDINATION OF CERTAIN CLASSES
 
     The rights of the holders of the Subordinate Certificates of a Certificate
Group to receive distributions with respect to the Mortgage Loans in the related
Loan Group or Loan Groups will be subordinated to such rights of the holders of
the Senior Certificates of such Certificate Group (which, in the case of the
Group C-B Certificates, are the Group I Senior and Group II Senior Certificates)
and to the Subordinate Certificates in such Certificate Group with lower
numerical Class designations. See 'Description of the Certificates -- Priority
of Distributions Among Certificates' and ' -- Cross-Collateralization' herein.
 
     The subordination of the Subordinate Certificates of a Certificate Group to
the related Senior Certificates and the further subordination within the
Subordinate Certificates of such Certificate Group is intended to provide
holders of Certificates with a higher relative payment priority protection
against Realized Losses other than Excess Losses. In addition, the Subordinate
Certificates of each Certificate Group will provide limited protection against
Special Hazard Losses, Bankruptcy Losses and Fraud Losses on the Mortgage Loans
in the related Loan Group (which, in the case of the Group C-B Certificates, are
the Group I and Group II Loans) up to the applicable Special Hazard Loss
Coverage Amount, Bankruptcy Loss Coverage Amount and Fraud Loss Coverage Amount,
respectively, as described below.
 
     The Group C-B Certificates will provide protection to the Group I and
Group II Certificates of higher relative priority against (i) Bankruptcy Losses
on the Group I and Group II Loans in an initial amount expected to be up to
approximately $144,715.45 (the 'Group I/Group II Bankruptcy Loss Coverage
Amount'), (ii) Fraud Losses on the Group I and Group II Loans in an initial
amount expected to be up to approximately $10,892,312.65 (the 'Group I/Group II
Fraud Loss Coverage Amount') and (iii) Special Hazard Losses on the Group I and
Group II Loans in an initial amount expected to be approximately $8,099,343.01
(the 'Group I/Group II Special Hazard Loss Coverage Amount').
 
     The Group III-B Certificates will provide protection to the Group III
Certificates of higher relative priority against (i) Bankruptcy Losses on the
Group III Loans in an initial amount expected to be up to approximately
$100,000.00 (the 'Group III Bankruptcy Loss Coverage Amount'), (ii) Fraud Losses
on the Group III Loans in an initial amount expected to be up to approximately
$6,100,861.81 (the 'Group III Fraud Loss Coverage Amount') and (iii) Special
Hazard Losses on the Group III Loans in an initial amount expected to be
approximately $3,678,918.55 (the 'Group III Special Hazard Loss Coverage
Amount').
 
     Investors in the Group I and Group II Certificates should be aware that
since the Group I/Group II Bankruptcy Loss Coverage Amount, the Group I/Group II
Fraud Loss Coverage Amount and the Group I/Group II Special Hazard Loss Coverage
Amount applies to both the Group I and Group II Loans, disproportionate
Bankruptcy Losses, Fraud Losses or Special Hazard Losses in one of such Loan
Groups will reduce the protection otherwise available to the Certificateholders
of the unrelated Certificate Group.
 
     The Special Hazard Loss Coverage Amounts will be reduced, from time to
time, to an amount equal on any Distribution Date to the lesser of (a) the
greatest of (i) 1% of the aggregate of the principal balances of the Mortgage
Loans in the related Loan Group or Loan Groups, (ii) twice the principal balance
of the largest Mortgage Loan in the related Loan Group or Loan Groups and (iii)
the aggregate principal balances of the Mortgage Loans in the related Loan Group
or Loan Groups secured by Mortgaged Properties located in the
 
                                      S-56

<PAGE>
single California postal zip code area having the highest aggregate principal
balance of any such zip code area and (b) such Special Hazard Loss Coverage
Amount as of the Closing Date less the amount, if any, of Special Hazard Losses
allocated to the Certificates in the related Certificate Group since the Closing
Date. All principal balances for the purpose of this definition will be
calculated as of the first day of the month preceding such Distribution Date
after giving effect to scheduled installments of principal and interest on the
Mortgage Loans then due, whether or not paid.
 
     The Fraud Loss Coverage Amounts will be reduced, from time to time, by the
amount of Fraud Losses on Mortgage Loans in the related Loan Group or Loan
Groups allocated to the related Certificates. In addition, on each anniversary
of the Cut-off Date, the Fraud Loss Coverage Amounts will be reduced as follows:
(a) on the first, second, third and fourth anniversaries of the Cut-off Date, to
an amount equal to the lesser of (i) 1% of the then current Stated Principal
Balances of, with respect to the Group I/Group II Fraud Loss Coverage Amount,
the Group I and Group II Loans and, with respect to the Group III Fraud Loss
Coverage Amount, the Group III Loans and (ii) the excess of such Fraud Loss
Coverage Amount as of the preceding anniversary of the Cut-off Date (or, in the
case of the first such anniversary, as of the Cut-off Date) over the cumulative
amount of Fraud Losses allocated to the Certificates of the related Certificate
Group since such preceding anniversary or the Cut-off Date, as the case may be,
and (b) on the fifth anniversary of the Cut-off Date, to zero.
 
     The Bankruptcy Loss Coverage Amount for each Certificate Group will be
reduced, from time to time, by the amount of Bankruptcy Losses on Mortgage Loans
in the related Loan Groups (which, in the case of the Group I/Group II
Bankruptcy Loss Coverage Amount, includes the Group I and Group II Loans)
allocated to the related Certificates.
 
     The amount of coverage provided by the Subordinate Certificates for Special
Hazard Losses, Bankruptcy Losses and Fraud Losses as described above may be
cancelled or reduced from time to time for each of the risks covered, provided
that the then current ratings of the Certificates assigned by the Rating
Agencies are not adversely affected thereby. In addition, a reserve fund or
other form of credit enhancement may be substituted for the protection provided
by the Subordinate Certificates for Special Hazard Losses, Bankruptcy Losses and
Fraud Losses.
 
     As used herein, a 'Deficient Valuation' is a bankruptcy proceeding whereby
the bankruptcy court may establish the value of the Mortgaged Property at an
amount less than the then outstanding principal balance of the Mortgage Loan
secured by such Mortgaged Property or may reduce the outstanding principal
balance of a Mortgage Loan. In the case of a reduction in the value of the
related Mortgaged Property, the amount of the secured debt could be reduced to
such value, and the holder of such Mortgage Loan thus would become an unsecured
creditor to the extent the outstanding principal balance of such Mortgage Loan
exceeds the value so 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 the reduction (a 'Debt Service
Reduction') of the amount of the monthly payment on the related Mortgage Loan.
Notwithstanding the foregoing, no such occurrence shall be considered a Debt
Service Reduction or Deficient Valuation so long as the related Servicer is
pursuing any other remedies that may be available with respect to the related
Mortgage Loan and (i) such Mortgage Loan is not in default with respect to
payment due thereunder or (ii) scheduled monthly payments of principal and
interest are being advanced by such Servicer without giving effect to any Debt
Service Reduction or Deficient Valuation. The Servicer will have no obligation
to advance payments in respect of any such Mortgage Loan that has suffered a
Deficient Valuation or Debt Service Reduction if the Servicer reasonably
believes such amount is not recoverable from future payments or collections on
such Mortgage Loan or proceeds of the liquidation of the related Mortgaged
Property.
 
                                USE OF PROCEEDS
 
     The Depositor will apply the net proceeds of the sale of the Offered
Certificates against the purchase price of the Mortgage Loans.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     For federal income tax purposes, the Trust Fund will include two segregated
asset pools, with respect to which elections will be made to treat each as a
separate REMIC. One REMIC (the 'Subsidiary REMIC') will issue several
uncertificated subclasses of nonvoting interests ('Subsidiary REMIC Regular
Interests'), which
 
                                      S-57
 

<PAGE>

<PAGE>
will be designated as the regular interests in the Subsidiary REMIC. The assets
of the Subsidiary REMIC will consist of the Mortgage Loans and all other
property in the Trust Fund except for the property in the Trust Fund allocated
to the second REMIC (the 'Master REMIC'). The Master REMIC will issue the
Regular Certificates, which will be designated as the regular interests in the
Master REMIC. The Class A-R Certificates will represent the beneficial ownership
of the residual interest in the Subsidiary REMIC and the residual interest in
the Master REMIC. The assets of the Master REMIC will consist of the Subsidiary
REMIC Regular Interests. Aggregate distributions on the subsidiary REMIC Regular
Interests will equal the aggregate distributions on the Regular Certificates
issued by the Master REMIC. See 'Description of the Certificates -- Separate
REMIC Structure' herein.
 
     The Regular Certificates generally will be treated as debt instruments
issued by the Master REMIC for federal income tax purposes. Income on the
Regular Certificates must be reported under an accrual method of accounting.
 
     The Class P Certificates will be treated for federal income tax purposes as
having been issued with an amount of OID equal to the difference between their
principal balance and their issue price. Although the tax treatment is not
entirely certain, Notional Amount Certificates will be treated as having been
issued with OID for federal income tax purposes equal to the excess of all
expected payments of interest on such Certificates over their issue price.
Although unclear, a holder of a Notional Amount Certificate may be entitled to
deduct a loss to the extent that its remaining basis exceeds the maximum amount
of future payments to which such Certificateholder would be entitled if there
were no further prepayments of the Mortgage Loans. The remaining Classes of
Regular Certificates, depending on their respective issue prices (as described
in the Prospectus under 'Certain Federal Income Tax Consequences'), may be
treated as having been issued with OID for federal income tax purposes. For
purposes of determining the amount and rate of accrual of OID and market
discount, the Trust Fund intends to assume that there will be prepayments on the
Group I, Group II and Group III at 100% of the applicable Prepayment Assumption.
No representation is made as to whether the Mortgage Loans will prepay at the
foregoing rate or any other rate. See 'Yield, Prepayment and Maturity
Considerations' herein and 'Certain Federal Income Tax Consequences' in the
Prospectus. Computing accruals of OID in the manner described in the Prospectus
may (depending on the actual rate of prepayments during the accrual period)
result in the accrual of negative amounts of OID on the Certificates issued with
OID in an accrual period. Holders will be entitled to offset negative accruals
of OID only against future OID accrual on such Certificates.
 
     If the holders of any Regular Certificates are treated as holding such
Certificates at a premium, such holders should consult their tax advisors
regarding the election to amortize bond premium and the method to be employed.
 
     As is described more fully under 'Certain Federal Income Tax Consequences'
in the Prospectus, the Offered Certificates will represent qualifying assets
under Sections 856(c)(4)(A) and 7701(a)(19)(C) of the Code, and net interest
income attributable to the Offered Certificates will be 'interest on obligations
secured by mortgages on real property' within the meaning of Section
856(c)(3)(B) of the Code, to the extent the assets of the Trust Fund are assets
described in such sections. The Regular Certificates will represent qualifying
assets under Section 860G(a)(3) if acquired by a REMIC within the prescribed
time periods of the Code.
 
     The holders of the Residual Certificates must include the taxable income of
the REMICs in their federal taxable income. The resulting tax liability of the
holders may exceed cash distributions to such holders during certain periods.
All or a portion of the taxable income from a Residual Certificate recognized by
a holder may be treated as 'excess inclusion' income, which, with limited
exceptions, is subject to U.S. federal income tax.
 
     The Small Business Job Protection Act of 1996 has eliminated the special
rule permitting Section 593 institutions ('thrift institutions') to use net
operating losses and other allowable deductions to offset their excess inclusion
income from REMIC residual certificates that have 'significant value' within the
meaning of the REMIC Regulations, effective for taxable years beginning after
December 31, 1995, except with respect to residual certificates continuously
held by a thrift institution since November 1, 1995.
 
     In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect on excess inclusions on the alternative minimum
taxable income of a residual holder. First, alternative minimum taxable income
for such residual holder is determined without regard to the special rule that
taxable income cannot be less than excess inclusions. Second, a residual
holder's alternative minimum taxable income for a tax year cannot be less than
the excess inclusions for the year. Third, the amount of any alternative minimum
tax net
 
                                      S-58
 

<PAGE>

<PAGE>
operating loss deductions must be computed without regard to any excess
inclusions. These rules are effective for tax years beginning after December 31,
1986, unless a residual holder elects to have such rules apply only to tax years
beginning after August 20, 1996.
 
     Furthermore, the Small Business Job Protection Act of 1996, as part of the
repeal of the bad debt reserve method for thrift institutions, repealed the
application of Code Section 593(d) to any taxable year beginning after December
31, 1995.
 
     Also, purchasers of a Residual Certificate should consider carefully the
tax consequences of an investment in Residual Certificates discussed in the
Prospectus and should consult their own tax advisors with respect to those
consequences. See 'Certain Federal Income Tax Consequences -- Taxation of Owners
of REMIC Residual Certificates' in the Prospectus. Specifically, prospective
holders of Residual Certificates should consult their tax advisors regarding
whether, at the time of acquisition, a Residual Certificate will be treated as a
'noneconomic' residual interest, a 'non-significant value' residual interest and
a 'tax avoidance potential' residual interest. See 'Certain Federal Income Tax
Consequences -- Taxation of Owners of REMIC Residual Certificates -- Noneconomic
REMIC Residual Certificates', 'Certain Federal Income Tax
Consequences -- Taxation of Owners of REMIC Residual
Certificates -- Mark-to-Market Rules', ' -- Excess Inclusions' and ' -- Foreign
Investors in REMIC Certificates' in the Prospectus. Additionally, for
information regarding Prohibited Transactions and Treatment of Realized Losses,
see 'Certain Federal Income Tax Consequences -- Taxation of Owners of REMIC
Residual Certificates -- Prohibited Transactions and Other Possible REMIC Taxes'
and ' -- Taxation of Owners of REMIC Regular Certificates -- Realized Losses' in
the Prospectus.
 
                              ERISA CONSIDERATIONS
 
     Any plan fiduciary which proposes to cause a Plan (as defined below) to
acquire any of the Offered Certificates should consult with its counsel with
respect to the potential consequences under the Employee Retirement Income
Security Act of 1974, as amended ('ERISA'), and/or the Code, of the Plan's
acquisition and ownership of such Certificates. See 'ERISA Considerations' in
the Prospectus. Section 406 of ERISA prohibits 'parties in interest' with
respect to an employee benefit plan subject to ERISA and/or the excise tax
provisions set forth under Section 4975 of the Code (a 'Plan') from engaging in
certain transactions involving such Plan and its assets unless a statutory or
administrative exemption applies to the transaction. Section 4975 of the Code
imposes certain excise taxes on prohibited transactions involving Plans and
other arrangements (including, but not limited to, individual retirement
accounts) described under that Section; ERISA authorizes the imposition of civil
penalties for prohibited transactions involving Plans not subject to the
requirements of Section 4975 of the Code.
 
     Certain employee benefit plans, including governmental plans and certain
church plans, are not subject to ERISA's requirements. Accordingly, assets of
such plans may generally be invested in the Offered Certificates without regard
to the ERISA considerations described herein and in the Prospectus, subject to
the provisions of other applicable federal and state law. Any such plan that is
qualified and exempt from taxation under Sections 401(a) and 501(a) of the Code
may nonetheless be subject to the prohibited transaction rules set forth in
Section 503 of the Code.
 
     Except as noted above, investments by Plans are subject to ERISA's general
fiduciary requirements, including the requirement of investment prudence and
diversification and the requirement that a Plan's investments be made in
accordance with the documents governing the Plan. A fiduciary that decides to
invest the assets of a Plan in the Offered Certificates should consider, among
other factors, the extreme sensitivity of the investment to the rate of
principal payments (including prepayments) on the Mortgage Loans.
 
     The U.S. Department of Labor has granted an individual administrative
exemption to the Underwriter (Prohibited Transaction Exemption 90-83, as amended
(the 'Exemption')), from certain of the prohibited transaction rules of ERISA
and the related excise tax provisions of Section 4975 of the Code with respect
to the initial purchase, the holding and the subsequent resale by Plans of
certificates in pass-through trusts that consist of certain receivables, loans
and other obligations that meet the conditions and requirements of the
Exemption. The Exemption applies to mortgage loans such as the Mortgage Loans in
the Trust Fund.
 
     For a general description of the Exemption and the conditions that must be
satisfied for the Exemption to apply, see 'ERISA Considerations' in the
Prospectus.

     It is expected that the Exemption will apply to the acquisition and holding
by Plans of the Senior Certificates (other than the Class A-R Certificates) and
that all conditions of the Exemption other than those within the control of the
investors will be met. In addition, as of the date hereof, there is no single
Mortgagor that is the obligor on five percent (5%) of the Mortgage Loans
included in the Trust Fund by aggregate unamortized principal balance of the
assets of the Trust Fund.
 
     BECAUSE THE CHARACTERISTICS OF THE CLASS C-B-1, CLASS C-B-2, CLASS C-B-3,
CLASS III-B-1, CLASS III-B-2, CLASS III-B-3 AND CLASS A-R CERTIFICATES WILL NOT
MEET THE REQUIREMENTS OF PTCE 83-1 (AS DESCRIBED IN THE PROSPECTUS) OR THE
EXEMPTION AND MAY NOT MEET THE REQUIREMENTS OF ANY OTHER ISSUED EXEMPTION UNDER
ERISA, THE PURCHASE AND HOLDING OF THE CLASS C-B-1, CLASS C-B-2, CLASS C-B-3,
CLASS III-B-1, CLASS III-B-2, CLASS III-B-3 AND CLASS A-R CERTIFICATES BY A PLAN
OR BY INDIVIDUAL RETIREMENT ACCOUNTS OR OTHER PLANS SUBJECT TO SECTION 4975 OF
THE CODE MAY RESULT IN PROHIBITED TRANSACTIONS OR THE IMPOSITION OF EXCISE TAXES
OR CIVIL PENALTIES. CONSEQUENTLY, TRANSFERS OF THE CLASS C-B-1, CLASS C-B-2,
CLASS C-B-3, CLASS III-B-1, CLASS III-B-2, CLASS III-B-3 AND CLASS A-R
CERTIFICATES WILL NOT BE REGISTERED BY THE TRUSTEE UNLESS THE TRUSTEE RECEIVES:
(I) A REPRESENTATION FROM THE TRANSFEREE OF SUCH CERTIFICATE, ACCEPTABLE TO AND
IN FORM AND SUBSTANCE SATISFACTORY TO THE TRUSTEE, TO THE EFFECT THAT SUCH
TRANSFEREE IS NOT AN EMPLOYEE BENEFIT PLAN SUBJECT TO SECTION 406 OF ERISA OR A
PLAN OR ARRANGEMENT SUBJECT TO SECTION 4975 OF THE CODE, NOR A PERSON ACTING ON
BEHALF OF ANY SUCH PLAN OR ARRANGEMENT NOR USING THE ASSETS OF ANY SUCH PLAN OR
ARRANGEMENT TO EFFECT SUCH TRANSFER; (II) IF THE PURCHASER IS AN INSURANCE
COMPANY, A REPRESENTATION THAT THE PURCHASER IS AN INSURANCE COMPANY WHICH IS
PURCHASING SUCH CERTIFICATES WITH FUNDS CONTAINED IN AN 'INSURANCE COMPANY
GENERAL ACCOUNT' (AS SUCH TERM IS DEFINED IN SECTION V(E) OF PROHIBITED
TRANSACTION CLASS EXEMPTION 95-60 ('PTCE 95-60')) AND THAT THE PURCHASE AND
HOLDING OF SUCH CERTIFICATES ARE COVERED UNDER SECTIONS I AND III OF PTCE 95-60;
OR (III) AN OPINION OF COUNSEL SATISFACTORY TO THE TRUSTEE THAT THE PURCHASE OR
HOLDING OF SUCH CERTIFICATE BY A PLAN, ANY PERSON ACTING ON BEHALF OF A PLAN OR
USING SUCH PLAN'S ASSETS, WILL NOT RESULT IN THE ASSETS OF THE TRUST FUND BEING
DEEMED TO BE 'PLAN ASSETS' AND SUBJECT TO THE PROHIBITED TRANSACTION
REQUIREMENTS OF ERISA AND THE CODE AND WILL NOT SUBJECT THE TRUSTEE OR ANY
SERVICER TO ANY OBLIGATION IN ADDITION TO THOSE UNDERTAKEN BY THEM IN THE
AGREEMENT. SUCH REPRESENTATION AS DESCRIBED ABOVE SHALL BE DEEMED TO HAVE BEEN
MADE TO THE TRUSTEE BY THE TRANSFEREE'S ACCEPTANCE OF A CLASS C-B-1, CLASS
C-B-2, CLASS C-B-3, CLASS III-B-1, CLASS III-B-2 OR CLASS III-B-3 CERTIFICATE.
IN THE EVENT THAT SUCH REPRESENTATION IS VIOLATED, OR ANY ATTEMPT TO TRANSFER TO
A PLAN OR PERSON ACTING ON BEHALF OF A PLAN OR USING SUCH A PLAN'S ASSETS IS
ATTEMPTED WITHOUT SUCH OPINION OF COUNSEL, SUCH ATTEMPTED TRANSFER OR
ACQUISITION SHALL BE VOID AND OF NO EFFECT.
 
     Prospective Plan investors should consult with their legal advisors
concerning the impact of ERISA and the Code, the applicability of the Exemption,
and the potential consequences in their specific circumstances, prior to making
an investment in the Offered Certificates. Moreover, each Plan fiduciary should
determine whether under the general fiduciary standards of investment prudence
and diversification, an investment in the Offered Certificates is appropriate
for the Plan, taking into account the overall investment policy of the Plan and
the composition of the Plan's investment portfolio.
 
                             METHOD OF DISTRIBUTION
 
     Subject to the terms and conditions set forth in the underwriting agreement
(the 'Underwriting Agreement') between the Depositor and Donaldson, Lufkin &
Jenrette Securities Corporation (the 'Underwriter'), an affiliate of the
Depositor, the Depositor has agreed to sell to the Underwriter, and the
Underwriter has agreed to purchase from the Depositor, the Offered Certificates.
 
     The Underwriting Agreement provides that the obligation of the Underwriter
to pay for and accept delivery of the Offered Certificates is subject to, among
other things, the receipt of certain legal opinions and to the conditions, among
others, that no stop order suspending the effectiveness of the Depositor's
Registration Statement shall be in effect, and that no proceedings for such
purpose shall be pending before or threatened by the Securities and Exchange
Commission.
 
     The distribution of the Offered Certificates by the Underwriter will be
effected from time to time in one or more negotiated transactions, or otherwise,
at varying prices to be determined, in each case, at the time of sale. The
proceeds to the Depositor from the sale of the Offered Certificates will be
approximately 99.879485% of the initial aggregate Class Principal Balance of the
Offered Certificates, plus accrued interest, before deducting expenses payable
by the Depositor. The Underwriter may effect such transactions by selling its
Certificates to or
 
                                      S-60
 

<PAGE>

<PAGE>
through dealers, and such dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Underwriter for whom
they act as agent. In connection with the sale of the Offered Certificates, the
Underwriter may be deemed to have received compensation from the Depositor in
the form of an underwriting discount. The Underwriter and any dealers that
participate with the Underwriter in the distribution of the Offered Certificates
may be deemed to be underwriters and any profit on the resale of the Offered
Certificates positioned by them may be deemed to be underwriting discounts and
commissions under the Securities Act of 1933, as amended.
 
     The Underwriting Agreement provides that the Depositor will indemnify the
Underwriter, and under limited circumstances the Underwriter will indemnify the
Depositor, against certain civil liabilities under the Securities Act of 1933,
as amended, or contribute to payments required to be made in respect thereof.
 
     There can be no assurance that a secondary market for the Offered
Certificates will develop or, if it does develop, that it will continue or will
provide investors with a sufficient level of liquidity. The primary source of
information available to investors concerning the Offered Certificates will be
monthly statements discussed in the Prospectus under 'The Agreements -- Reports
to Securityholders', which will include information as to the outstanding
principal balance of the Offered Certificates and the status of the applicable
form of credit enhancement. There can be no assurance that any additional
information regarding the Offered Certificates will be available through any
other source.
 
                                 LEGAL MATTERS
 
     The validity of the Certificates, including certain federal income tax
consequences with respect thereto, will be passed upon for the Depositor by
Brown & Wood LLP, New York, New York. Brown & Wood LLP, New York, New York, will
pass upon certain legal matters on behalf of the Underwriter.

     It is a condition of the issuance of the Offered Certificates that they

     The ratings assigned by DCR to mortgage pass-through certificates address
the likelihood of the receipt by certificateholders of all distributions to
which they are entitled under the transaction structure. DCR's ratings reflect
its analysis of the riskiness of the mortgage loans and its analysis of the
structure of the transaction as set forth in the operative documents. DCR's
ratings do not address the effect on the certificates' yield attributable to
prepayments or recoveries on the underlying mortgage loans. Further, the ratings
on the Notional Amount Certificates do not address whether investors will recoup
their initial investment. The ratings assigned by DCR to the Class P
Certificates only address the return of their stated principal balance. The
rating assigned by DCR to the Class A-R Certificates only addresses the return
of its Class Certificate Balance and interest thereon at its stated Pass-Through
Rate.
 
     The ratings assigned by S&P to mortgage pass-through certificates address
the likelihood of the receipt of all distributions on the mortgage loans by the
related Certificateholders under the agreements pursuant to which such
certificates are issued. S&P's ratings take into consideration the credit
quality of the related mortgage pool, including any credit support providers,
structural and legal aspects associated with such certificates, and the extent
to which the payment stream on such mortgage pool is adequate to make payments
required by such certificates. S&P's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans. The 'r' symbol is appended to the rating by S&P of those
Certificates that S&P believes may experience high volatility or high
variability in expected returns due to non-credit risks. The absence of any 'r'
symbol in the ratings of the other Offered Certificates should not be taken as
an indication that such Certificates will exhibit no volatility or variability
in total return.
 
     The ratings of Fitch on mortgage pass-through certificates address the
likelihood of the receipt by certificateholders of all distributions to which
such certificateholders are entitled. Fitch's rating opinions address the
structural, legal and issuer aspects associated with the certificates, including
the nature of the underlying mortgage loans and the credit quality of the credit
support provider, if any. Fitch's ratings on mortgage pass-through certificates
do not represent any assessment of the likelihood or rate of principal
prepayments.
 
     The ratings of the Rating Agencies do not address the possibility that, as
a result of principal prepayments, Certificateholders may receive a lower than
anticipated yield.
 
     The ratings assigned to the Offered Certificates should be evaluated
independently from similar ratings on other types of securities. A rating is not
a recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the Rating Agencies.
 
     The Depositor has not requested a rating of the Offered Certificates by any
rating agency other than the Rating Agencies; there can be no assurance,
however, as to whether any other rating agency will rate the Offered
Certificates or, if it does, what rating would be assigned by such other rating
agency. The rating assigned by such other rating agency to the Offered
Certificates could be lower than the respective ratings assigned by the Rating
Agencies.

                                   DEPOSITOR
 
                       MORTGAGE PASS-THROUGH CERTIFICATES
                             MORTGAGE-BACKED NOTES
                              (ISSUABLE IN SERIES)
 
     This Prospectus relates to Mortgage Pass-Through Certificates (the
'Certificates') and Mortgage-Backed Notes (the 'Notes', and together with the
Certificates, the 'Securities') which may be sold from time to time under this
Prospectus and related Prospectus Supplement in one or more series (each a
'Series') by DLJ Mortgage Acceptance Corp. (the 'Depositor'). Capitalized terms
not otherwise defined herein have the meanings specified in the Glossary
attached hereto.
 
     Each Certificate of a Series will evidence a beneficial ownership interest
in a related trust (a 'Trust Fund'), the assets of which have been deposited by
the Depositor pursuant to a Pooling and Servicing Agreement executed by the
Depositor, the Trustee and the Master Servicer for such Series specified in the
related Prospectus Supplement. Each Note of a Series will represent indebtedness
of a Trust Fund, the assets of which have been deposited by the Depositor
pursuant to a Sale and Servicing Agreement executed by the Depositor, the
Trustee and the Master Servicer or pursuant to an Indenture executed by the
Issuer and the Trustee for such Series specified in the related Prospectus
Supplement. The Trust Fund will consist of Mortgage Assets, which may include
Mortgage Loans or participation interests therein, Manufactured Home Loans or
participation interests therein, Agency Securities, Private Mortgage-Backed
Securities or any combination of the foregoing and other assets, including any
insurance policies, reserve funds or other forms of credit support specified in
the related Prospectus Supplement. Manufactured Home Loans and the Mortgage
Loans in the Trust Fund for a Series will have been originated by various
financial institutions and other entities engaged generally in the business of
originating and/or servicing housing loans and will have been acquired by the
Depositor from one or more Sellers on or prior to the Closing Date. Some of the
Mortgage Loans or Manufactured Home Loans may have been originated by an
affiliate of the Depositor. The Mortgage Loans and the Manufactured Home Loans
may include (without limitation) fixed rate or adjustable rate Conventional
Loans, FHA Loans or VA Loans and may provide for graduated equity, graduated
payment, balloon payment, 'buy-down' or other payment features, and may call for
payments from the obligors other than monthly, as specified in the related
Prospectus Supplement, Mortgage Loans underlying or comprising the Mortgage
Assets will be secured by property consisting of single family (one-to-four
family) attached or detached residential housing or multifamily residential
rental properties or cooperatively owned properties consisting of five or more
attached or detached dwelling units. Mortgage Loans that are Cooperative Loans
will be secured by assignments of shares and a proprietary lease or occupancy
agreement on a cooperative apartment. Manufactured Home Loans underlying or
comprising the Mortgage Assets will be secured by property consisting of a
Manufactured Home. See 'The Trust Funds' herein. Manufactured Home Loans and the
Mortgage Loans (or participation interests therein) will be serviced by various
servicers under the supervision of the Master Servicer or by the Master Servicer
directly as specified in the related Prospectus Supplement. The Master
Servicer's and any Servicer's obligations will be limited to its contractual,
supervisory and/or servicing obligations and such other obligations as are
specified in the related Prospectus Supplement. See 'Servicing of Loans' herein.

     PROCEEDS OF THE ASSETS IN THE TRUST FUND ARE THE SOLE SOURCE OF PAYMENTS ON
THE SECURITIES. THE SECURITIES DO NOT REPRESENT AN INTEREST IN OR OBLIGATION OF
THE DEPOSITOR, THE MASTER SERVICER OR ANY OF THEIR AFFILIATES. NEITHER THE
SECURITIES NOR THE UNDERLYING MORTGAGE LOANS OR MORTGAGE SECURITIES WILL BE
GUARANTEED OR INSURED BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY OR BY THE
DEPOSITOR, THE MASTER SERVICER OR ANY OF THEIR AFFILIATES.

     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
CONTRARY IS A CRIMINAL OFFENSE.
 
     Securities of a Series offered hereby and by the related Prospectus
Supplement may be made through one or more different methods, including
offerings through Donaldson, Lufkin & Jenrette Securities Corporation, an
affiliate of the Depositor, as more fully described herein and in the related

     Each Series of Securities will consist of one or more Classes, and any
Class may include subclasses. If a Series includes multiple Classes, such
Classes may vary with respect to the amount, percentage and timing of
distributions of principal, interest or both and one or more Classes may be
subordinated to other Classes with respect to distributions of principal,
interest or both as described herein and in the related Prospectus Supplement.
If so specified in the related Prospectus Supplement, the Mortgage Assets held
under the related Agreement may be divided into one or more Asset Groups and the
Securities of each separate Class will evidence beneficial ownership of each
corresponding Asset Group. See 'Description of the Securities' herein.
 
     Distribution of principal and interest of the Securities of each Series
will be made on each Distribution Date for a Series. The rate of reduction of
the aggregate principal balance of each Class of a Series will depend
principally upon the rate of payment (including prepayments) with respect to the
Loans comprising or underlying the Mortgage Assets. A rate of prepayment lower
or higher than anticipated may affect yield on the Securities of a Series in the
manner described herein and in the related Prospectus Supplement. Under certain
limited circumstances described herein and in the related Prospectus Supplement,
the Mortgage Assets may be purchased by the entity specified in the related
Prospectus Supplement and the related Trust Fund terminated prior to the
maturity of the Mortgage Assets or the Final Scheduled Distribution Date of the
Securities of the related Series. See 'Description of the Securities' and
'Yield, Prepayment and Maturity Considerations' herein.
 
     The Depositor's only obligations with respect to any Series will be
pursuant to certain representations and warranties, if any, set forth in the
related Agreement as described herein or in the related Prospectus Supplement.
See 'The Agreements' herein.
 
     If specified in the related Prospectus Supplement, one or more separate
elections may be made to treat the Trust Fund for a Series of Certificates as a
'Real Estate Mortgage Investment Conduit' (a 'REMIC') for federal income tax
purposes. See 'Certain Federal Income Tax Considerations' herein.

EFFECTING TRANSACTIONS IN THE SECURITIES OFFERED HEREBY, WHETHER OR NOT

SECURITIES OFFERED...............  The Mortgage Pass-Through Certificates (the 'Certificates') or the Mort-
                                   gage-Backed Notes (the 'Notes', and together with the Certificates, the
                                   'Securities') are issuable from time to time in separate Series pursuant to
                                   separate Pooling and Servicing Agreements or separate Indentures, respec-
                                   tively. Each Certificate of a Series will evidence a beneficial ownership
                                   interest in, and each Note of a Series will represent indebtedness of the
                                   related Trust Fund for such Series, or in an Asset Group specified in the
                                   related Prospectus Supplement.
                                   The Certificates of a Series will evidence interests in, and the Notes of a
                                   Series will represent indebtedness of the related Trust Fund only and will not
                                   be guaranteed by any governmental agency, by the Depositor, the Trustee, the
                                   Master Servicer or by any of their respective affiliates, or unless otherwise
                                   specified in the related Prospectus Supplement, by any other person or entity.
                                   See 'Risk Factors' and 'Credit Support' herein.
                                   Each Series of Securities will consist of one or more Classes. If a Series
                                   consists of multiple Classes, the respective Classes may differ with respect
                                   to the amount, percentage and timing of distributions of principal, interest
                                   or both. Additionally, one or more Classes may consist of Subordinate
                                   Securities which are subordinated to other Classes of Securities with respect
                                   to the right to receive distributions of principal, interest, or both under
                                   the circumstances and in such amounts as described herein and in the related
                                   Prospectus Supplement. With respect to any Series of Notes, the related Equity
                                   Certificates, insofar as they represent the beneficial ownership interest in
                                   the Issuer, will be subordinate to the related Notes. Unless otherwise
                                   specified in the related Prospectus Supplement, any Class of Securities of a
                                   Series will be offered hereby and by such Prospectus Supplement only if rated
                                   by at least one Rating Agency in one of its four highest rating categories.

                                   Subordinated Securities' and 'Risk Factors' herein.
DEPOSITOR........................  DLJ Mortgage Acceptance Corp., a Delaware corporation (the 'Depositor'), is a
                                   limited purpose corporation organized primarily for the purpose of investing
                                   in the Mortgage Assets for each Trust Fund. All of the outstanding capital
                                   stock of the Depositor is owned by Donaldson, Lufkin & Jenrette, Inc. See 'The
                                   Depositor.'
MASTER SERVICER..................  The entity named as Master Servicer in the related Prospectus Supplement. See
                                   'The Agreements.'
ISSUER...........................  With respect to each Series of Notes, the issuer (the 'Issuer') will be the
                                   Depositor or an owner trust established by it for the purpose of issuing such
                                   Series of Notes. Each such owner trust will be created pursuant to a trust
                                   agreement (the 'Owner Trust Agreement') between the Depositor, acting as
                                   depositor and the owner trustee (the 'Owner Trustee'). Each Series of Notes
                                   will represent indebtedness of the Issuer and will be issued pursuant to an
                                   indenture (the 'Indenture') between the Issuer and the Trustee whereby the

                                   Issuer will pledge the Trust Fund to secure the Notes under the lien of the
                                   Indenture. As to each Series of Notes where the Issuer is an owner trust, the
                                   ownership of the Trust Fund will be evidenced by certificates (the 'Equity
                                   Certificates') issued under the Owner Trust Agreement. The Notes will
                                   represent nonrecourse obligations solely of the Issuer, and the proceeds of
                                   the Trust Fund will be the sole source of payments on the Notes, except as
                                   described herein under 'Credit Support' and in the related Prospectus
                                   Supplement.
TRUSTEES.........................  The Trustee or Indenture Trustee (each, the 'Trustee') with respect to each
                                   Series of Certificates and each Series of Notes, respectively, will be
                                   specified in the related Prospectus Supplement. The Owner Trustee with respect
                                   to each Series of Notes will be specified in the related Prospectus
                                   Supplement.
INTEREST DISTRIBUTIONS...........  Interest Distributions on the Securities of a Series will be made from amounts
                                   available therefor in the related Certificate Account on each Distribution
                                   Date at the applicable security interest rate (a 'Security Interest Rate')
                                   specified in (or, with respect to Floating Interest Securities, determined in
                                   the manner set forth in) the related Prospectus Supplement. The Security
                                   Interest Rate of each Security offered hereby will be stated in the related
                                   Prospectus Supplement as the 'Pass-Through Rate' with respect to a Series of a
                                   single Class of Certificates, the 'Certificate Rate' with respect to a
                                   Multiple Class Series of Certificates and the 'Note Interest Rate' with
                                   respect to any Series of Notes. The Security Interest Rate on Securities of a
                                   Series may be variable and change with changes in the mortgage rate or
                                   pass-through rates of the Mortgage Assets included in the related Trust Fund
                                   and/or as prepayments occur with respect to such Mortgage Assets.
                                   Principal Weighted Securities may not be entitled to receive any interest
                                   distributions or may be entitled to receive only nominal interest
                                   distributions.
                                   Compound Interest Securities will not receive distributions of interest but
                                   interest accruing with respect to the principal balance of such compound
                                   Interest Securities will be added to such principal balance on each
                                   Distribution Date until the Accrual Termination Date. Following the Accrual
                                   Termination Date, interest distributions with respect to such Compound
                                   Interest Securities will be made on the basis of their Compound Value.
                                   A Multiple Class Series may include one or more Classes of Floating Interest
                                   Securities. With respect to any such Class of Floating Interest Securities,
                                   the related Prospectus Supplement will set forth: (a) the initial Floating
                                   Rate (or manner of determining the initial Floating Rate); (b) the method by
                                   which the Floating Rate will be determined from time to time; (c) the periodic
                                   intervals at which such determination will be made; and (d) the Maximum
                                   Floating Rate and the Minimum Floating Rate, if any. See 'Description of the
                                   Securities' and 'Yield, Prepayment and Maturity Considerations' herein.
PRINCIPAL DISTRIBUTIONS..........  Principal distributions on the Securities of a Series will be made from
                                   amounts available therefor in the related Certificate Account on each
                                   Distribution Date in an aggregate amount determined as specified in the
                                   related Prospectus Supplement. Principal distributions will be allocated among
                                   the respective Classes of a Series in the manner and in the priority set forth
                                   in the related Prospectus Supplement.

                                   Interest Weighted Securities may not be entitled to any principal distribu-
                                   tions or may be entitled to receive only nominal principal distributions.
                                   See 'Description of the Securities' and 'Yield, Prepayment and Maturity
                                   Considerations' herein.
FUNDING ACCOUNT..................  If so specified in the related Prospectus Supplement, a portion of the
                                   proceeds of the sale of one or more Classes of Securities of a Series or a
                                   portion of collections on the Loans in respect of principal may be deposited
                                   in a segregated account to be applied to acquire additional Loans, subject to
                                   the limitations set forth herein under 'Description of the Securities --
                                   Funding Account.' Monies on deposit in the Funding Account and not applied to
                                   acquire such additional Loans within the time set forth in the related
                                   Agreement or other applicable agreement may be treated as principal and
                                   applied in the manner described in the related Prospectus Supplement.
OPTIONAL TERMINATION.............  If so specified in the related Prospectus Supplement, the Depositor, the
                                   Master Servicer, or such other entity that is specified in the related
                                   Prospectus Supplement, may, at its option, cause an early termination of the
                                   related Trust Fund by repurchasing all of the Mortgage Assets remaining in the
                                   Trust Fund on or after a specified date, or on or after such time as the
                                   aggregate unpaid principal balance of the Mortgage Assets is less than the
                                   percentage specified in the related Prospectus Supplement. See 'Description of
                                   the Securities -- Optional Termination.'
THE TRUST FUND...................  The Trust Fund for a Series will consist of Private Mortgage-Backed
                                   Securities, Agency Securities, Mortgage Loans or participation interests
                                   therein, Manufactured Home Loans or participation interests therein, or any
                                   combination of the foregoing (the 'Mortgage Assets'), together with certain
                                   accounts, reserve funds, insurance policies and related agreements specified
                                   in the related Prospectus Supplement. (Mortgage Loans and Manufactured Home
                                   Loans are referred to herein as 'Loans.') If so specified in the related
                                   Prospectus Supplement, the Mortgage Assets may be divided into Asset Groups
                                   and the Securities of separate Classes will evidence beneficial interests of a
                                   corresponding Asset Group. The Trust Fund for a Series will also include the
                                   Collection Account, the Certificate Account, and may include certain policies
                                   of insurance relating to the Mortgage Assets, and various forms of credit
                                   support, all as specified in the related Prospectus. See 'The Trust
                                   Funds -- Collection Account and Certificate Account' and 'Credit Support' and
                                   'Description of Mortgage and Other Insurance' herein.
CREDIT SUPPORT...................  Credit support in the form of reserve funds, subordination, overcollateraliza-
                                   tion, insurance policies, letters of credit or other types of credit support
                                   may be provided with respect to the Mortgage Assets or with respect to one or
                                   more Classes of Securities of a Series. If the Mortgage Assets are divided
                                   into separate Asset Groups, the beneficial ownership of which is evidenced by
                                   a separate Class or Classes of a Series, credit support may be provided by a
                                   cross-support feature which requires that distributions be made with respect
                                   to Securities evidencing beneficial ownership of one Asset Group prior to
                                   distributions to Subordinate Securities evidencing a beneficial ownership
                                   interest in another Asset Group within the Trust Fund. With respect to any
                                   Series of Notes, the related Equity Certificates, insofar as they represent
                                   the beneficial ownership interest in the Issuer, will be subordinate to the
                                   related Notes.

                                   The type, characteristics and amount of credit support will be determined
                                   based on the characteristics of the Loans underlying or comprising the
                                   Mortgage Assets and other factors and will be established on the basis of
                                   requirements of each Rating Agency rating the Securities of such Series. The
                                   protection against losses provided by such credit support will be limited. See
                                   'Credit Support' and 'Risk Factors' herein.
SERVICING OF LOANS...............  The Master Servicer identified in the related Prospectus Supplement will
                                   service the Loans directly or administer and supervise the performance by
                                   Servicers of their duties and responsibilities under separate servicing
                                   agreements (the 'Sub-Servicing Agreements') entered into between the Master
                                   Servicer and such Servicers. Unless otherwise specified in the related
                                   Prospectus Supplement, the Master Servicer and each Servicer must be approved
                                   by either FNMA or FHLMC as a seller/servicer of Mortgage Loans and, in the
                                   case of FHA Loans, approved by HUD as an FHA mortgagee. Each Servicer will be
                                   obligated under its Sub-Servicing Agreement to perform customary servicing
                                   functions. Advances with respect to delinquent payments of principal or
                                   interest on a Loan will be made by the Master Servicer or the Servicers only
                                   to the extent described in the related Prospectus Supplement. Such advances
                                   will be intended to provide liquidity only and, unless otherwise specified in
                                   the related Prospectus Supplement, will be reimbursable to the Master Servicer
                                   or the Servicer, as the case may be, from scheduled payments of principal and
                                   interest, late collections, or from the proceeds of liquidation of the related
                                   Loans, from other recoveries relating to such Loans (including any insurance
                                   proceeds or payments from other forms of credit support). See 'Servicing of
                                   Loans.'
FEDERAL INCOME TAX
  CONSIDERATIONS.................  If an election is made for treatment of the Trust Fund as a REMIC or as REMICs
                                   under the Internal Revenue Code of 1986 (the 'Code'), one or more Classes of
                                   Certificates will be REMIC 'Regular Interests' and one Class will be REMIC
                                   'Residual Interests' in the related REMIC. If a REMIC election will not be
                                   made for a Trust Fund, the federal income consequences of the purchase,
                                   ownership and disposition of the related Certificates will be set forth in the
                                   related Prospectus Supplement. Each Series of Notes offered hereby will
                                   represent indebtedness of the related Trust Fund.
                                   Investors are advised to consult their tax advisors and to review 'Certain
                                   Federal Income Tax Considerations' herein and in the related Prospectus
                                   Supplement. See 'Certain Federal Income Tax Considerations.'
ERISA CONSIDERATIONS.............  A fiduciary of any employee benefit plan subject to the Employee Retirement
                                   Income Security Act of 1974, as amended ('ERISA'), or the Code should
                                   carefully review with its own legal advisors whether the purchase or holding
                                   of Securities could give rise to a transaction prohibited or otherwise
                                   impermissible under ERISA or the Code. See 'ERISA Considerations.'
LEGAL INVESTMENT.................  At the date of issuance, as to each Series, it will be a requirement for
                                   issuance of any Series that the Securities offered by this Prospectus and such
                                   Prospectus Supplement be rated by at least one Rating Agency in one of its
                                   four highest applicable rating categories. The rating or ratings applicable to
                                   Securities of each Series offered hereby and by the related Prospectus
                                   Supplement will be as set forth in the related Prospectus Supplement. Unless
                                   otherwise specified in the related Prospectus Supplement, Securities of each

                                   Series offered by this Prospectus and such Prospectus Supplement will
                                   constitute 'mortgage related securities' under the Secondary Mortgage Market
                                   Enhancement Act of 1984 ('SMMEA') so long as they are rated by at least one
                                   Rating Agency in one of its two highest categories and, as such, will be legal
                                   investments for certain types of institutional investors to the extent
                                   provided in SMMEA, subject, in any case, to any other regulations which may
                                   govern investments by such institutional investors. Any Class of Securities
                                   that represents an interest in a Trust Fund that includes junior mortgage
                                   loans will not constitute 'mortgage related securities' for purposes of SMMEA.
                                   See 'Legal Investment.'
USE OF PROCEEDS..................  The Depositor will use the net proceeds from the sale of each Series for one
                                   or more of the following purposes: (i) to purchase the related Mortgage
                                   Assets, (ii) to repay indebtedness which has been incurred to obtain funds to
                                   acquire such Mortgage Assets, (iii) to establish any reserve funds described
                                   in the related Prospectus Supplement and (iv) to pay costs of structuring,
                                   guaranteeing and issuing such Securities. If so specified in the related
                                   Prospectus Supplement, the purchase of the Mortgage Assets for a Series may be
                                   effected by an exchange of Securities with the Depositor of such Mortgage
                                   Assets. See 'Use of Proceeds.'

                                  RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with an investment in the Securities.
 
LIMITED LIQUIDITY
 
     There can be no assurance that a secondary market for the Securities of any
Series will develop or, if it does develop, that it will provide Securityholders
with a sufficient level of liquidity or will continue for the life of the
Securities. Donaldson, Lufkin & Jenrette Securities Corporation (or one or more
of its affiliates) intends to make a secondary market in the Securities, but has
no obligation to do so. In addition, the market value of Securities of each
Series will fluctuate with changes in prevailing rates of interest.
Consequently, sale of the Securities by a Holder in any secondary market which
may develop may be at a discount from par value or from their purchase price.
Securityholders have no optional redemption rights. The Securities will not be
listed on any securities exchange.
 
YIELD, PREPAYMENT AND MATURITY
 
     The rate at which prepayments (which include both voluntary prepayments by
the obligors on the Loans and liquidations due to defaults and foreclosures)
occur on the Loans underlying or comprising the Mortgage Assets for a Series
will be affected by a variety of factors, including, without limitation, the
level of prevailing mortgage market interest rates and economic, demographic,
tax, social, legal and other factors. Prepayments on the Loans comprising or
underlying the Mortgage Assets for a Series generally will result in a faster
rate of distributions of principal on the Securities. Thus, the prepayment
experience on the Loans comprising or underlying the Mortgage Assets will affect
the average life and yield to investors of each Class and the extent to which
each such Class is paid prior to its Final Scheduled Distribution Date. A Series
may include an Interest Weighted Class offered at a significant premium or a
Principal Weighted Class offered at a substantial discount. Yields on such
Classes of Securities will be extremely sensitive to prepayments on the Loans
comprising or underlying the Mortgage Assets for such Series. In general, if a
Security, including a Security of an Interest Weighted Class, is purchased at a
premium and principal distributions on the Loans occur at a rate faster than
anticipated at the time of purchase, the investor's actual yield to maturity
could be significantly lower than that assumed at the time of purchase. Where
the amount of interest allocated with respect to an Interest Weighted Class is
extremely disproportionate to principal, a Securityholder of such Class could,
under some such prepayment scenarios, fail to recoup its original investment.
Conversely, if a Security, including a Security of a Principal Weighted Class,
is purchased at a discount and principal distributions thereon occur at a rate
slower than assumed at the time of purchase, the investor's actual yield to
maturity could be significantly lower than that originally anticipated. Any
rating assigned to the Securities by a Rating Agency will reflect only such
Rating Agency's assessment of the likelihood that timely distributions will be
made with respect to such Securities in accordance with the related Agreement.
Such rating will not constitute an assessment of the likelihood that principal
prepayments on the Loans underlying or comprising the Mortgage Assets will be
made by borrowers or of the degree to which the rate of such prepayments might
differ from that originally anticipated. As a result, such rating will not
address the possibility that prepayment rates higher or lower than anticipated
by an investor may cause such investor to experience a lower than anticipated
yield, or that an investor purchasing an Interest Weighted Security at a
significant premium might fail to recoup its initial investment. See 'Yield,
Prepayment and Maturity Considerations.'
 
CREDIT SUPPORT LIMITATIONS
 
     The amount, type and nature of insurance policies, subordination,
overcollateralization, Financial Guarantee Insurance, letters of credit and
other credit support, if any, required with respect to a Series will be
determined on the basis of criteria established by each Rating Agency rating
such Series. Such criteria are necessarily based upon an actuarial analysis of
the behavior of Loans in a larger group. Such actuarial analysis is the basis
upon which each Rating Agency determines (a) required amounts and types of pool
insurance, special hazard insurance, reserve funds, subordination,
overcollateralization or other credit support and (b) limits on the number and
amount of Loans which have various special payment characteristics, have various
Loan-to-Value Ratios and/or were made for various purposes (e.g., primary
residence, second home, refinancing). There can be
 
                                       9
 

<PAGE>

<PAGE>
no assurance that the historical data supporting such actuarial analysis will
accurately reflect future experience nor any assurance that the data derived
from a large pool of housing loans accurately predicts the delinquency,
foreclosure or loss experience of any particular pool of Loans.
 
     In addition, if distributions in reduction of the principal balance of
Securities of a Multiple Class Series are made in order of the respective Final
Scheduled Distribution Dates of the Class, any limits with respect to the
aggregate amount of losses covered by credit support may be exhausted before the
principal of the later-maturing Classes has been repaid. As a result, the impact
of significant losses on the Mortgage Loans may bear primarily upon the
Securities of the later-maturing Classes.
 
     The Prospectus Supplement for a Series will describe any reserve funds,
insurance policies, letter of credit or other third-party credit support
relating to the Mortgage Assets or to the Securities of such Series. Use of such
reserve funds and payments under such insurance policies, letter of credit or
other third-party credit support will be subject to the conditions and
limitations described herein and in the related Prospectus Supplement. Moreover,
such reserve funds, insurance policies, letter of credit or other credit support
will not cover all potential losses or risks. The obligations of the issuers of
any credit support such as a pool insurance policy, special hazard insurance
policy, bankruptcy bond, letter of credit, Financial Guarantee Insurance,
repurchase bond or other third-party credit support will not be guaranteed or
insured by the United States, or by any agency or instrumentality thereof. A
Series of Securities may include a Class or multiple Classes of Subordinate
Securities to the extent described in the related Prospectus Supplement.
Although such subordination is intended to reduce the risk of delinquent
distributions or ultimate losses to Holders of Senior Securities, the
Subordinated Amount will be limited and will decline under certain circumstances
and the related Subordination Reserve Fund, if any, could be depleted in certain
circumstances. See 'Description of the Securities,' 'The Trust Funds' and
'Credit Support.'
 
CERTAIN LOANS AND MORTGAGED PROPERTY
 
     Reliable prepayment, loss and foreclosure statistics relating to certain
types of Loans may not be available for a Series. Such Loans may be underwritten
on the basis of an assessment that the borrower will have the ability to make
payments in higher amounts in later years and, in the case of Loans with
adjustable mortgage rates, after relatively short periods of time. See 'Loan
Underwriting Procedures and Standards' and 'Credit Support.' Other loans may be
underwritten principally on the basis of the initial Loan-to-Value Ratio of the
Loans. To the extent losses on Loans exceed the amount of credit support, the
Trust Fund may experience a loss. Furthermore, Multifamily Loans, Manufactured
Homes or Cooperative Dwellings may entail risks of loss in the event of
delinquency and foreclosure or repossession that are greater than similar risks
associated with traditional single-family property. To the extent losses on such
Loans exceed levels estimated by the Rating Agency in determining required
levels of subordination or other credit support, the Trust Fund may experience a
loss. See 'Servicing of Loans -- Maintenance of Insurance Policies and Other
Servicing Procedures' and 'Credit Support.'
 
LIMITED OBLIGATIONS AND ASSETS OF DEPOSITOR
 
     Unless otherwise set forth in the Prospectus Supplement for a Series of
Securities, the Trust Fund for a Series will be the only available source of
funds to make distributions on the Securities of such Series. The only
obligations of the Depositor with respect to the Securities of any Series will
be pursuant to certain representations and warranties, if any, in the related
Agreement. See 'The Agreements -- Assignment of Mortgage Assets' herein. The
Depositor does not have, and is not expected in the future to have, any
significant assets with which to meet any obligation to repurchase Mortgage
Assets with respect to which there has been a breach of any representation or
warranty. If, for example, the Depositor were required to repurchase a Loan
which constitutes a Mortgage Asset, its only sources of funds to make such
repurchase would be from funds obtained from the enforcement of a corresponding
obligation, if any, on the part of the Seller, the Servicer or the Master
Servicer, as the case may be, or from a reserve fund established to provide
funds for such repurchases. See 'The Depositor.'

INABILITY OF TRUSTEE TO LIQUIDATE THE COLLATERAL SECURING THE NOTES
 
     Although the Trustee or the holders of a majority of the then aggregate
outstanding amount of the Notes of a Series may declare the principal amount of
all the Notes of such Series to be due and payable immediately if an Event of
Default occurs and is continuing under the related Indenture, there is no
assurance that the market value of the related collateral will at any time be
equal to or greater than the aggregate outstanding amount of the related Notes.
Therefore, upon an Event of Default with respect to the related Notes, there can
be no assurance that sufficient funds will be available to repay the related
Noteholders in full. In addition, the amount of principal required to be
distributed to Noteholders under the Indenture is generally limited to amounts
available to be deposited in the applicable Certificate Account. Therefore, the
failure to pay principal on a class of the related Notes may not result in the
occurrence of an Event of Default until the Final Scheduled Distribution Date
for such class of Notes.
 
SUMMARY OF ERISA CONSIDERATIONS
 
     Generally, ERISA applies to investments made by employee benefit plans and
transactions involving the assets of such plans. Due to the complexity of
regulations which govern such plans, prospective investors that are subject to
ERISA are urged to consult their own counsel regarding consequences under ERISA
of acquisition, ownership and disposition of the Securities of any Series. See
'ERISA Considerations' herein and in the related Prospectus Supplement.
 
CERTAIN FEDERAL TAX CONSIDERATIONS REGARDING REMIC RESIDUAL INTERESTS
 
     Holders of REMIC Residual Interests will be required to report on their
federal income tax returns as ordinary income their pro rata share of the
taxable income of the related REMIC regardless of the amount or timing of their
receipt of cash payments as described in 'Certain Federal Income Tax
Considerations -- Residual Interests in a REMIC.' Accordingly, under certain
circumstances, holders of Certificates which constitute REMIC Residual Interests
might have taxable income and tax liabilities arising from such investment
during a taxable year in excess of the cash received during such period. The
requirement that Holders of Residual Interest Certificates report their pro rata
share of the taxable income and net loss of the related REMIC will continue
until the principal balances of all Classes of Certificates of the related
Series have been reduced to zero, even though holders of Residual Interests have
received full payment of their stated interest and principal. A portion (or, in
certain circumstances, all) of a Residual Interest Certificateholder's share of
the related REMIC's taxable income may be treated as 'excess inclusion' income
to such holder which (i) except in the case of certain thrift institutions, will
not be subject to offset by losses from other activities, (ii) for a tax-exempt
Holder, will be treated as unrelated business taxable income and (iii) for a
foreign holder, will not qualify for exemption from withholding tax. Individual
Holders of Certificates constituting Residual Interests may be limited in their
ability to deduct servicing fees and other expenses of the related REMIC.
Because of the special tax treatment of REMIC residual interests, the taxable
income arising in a given year on a REMIC residual interest will not be equal to
the taxable income associated with investment in a corporate bond or stripped
instrument having similar cash flow characteristics and pre-tax yield.
Therefore, the after-tax yield on the Residual Interest Certificates may be
negative or significantly less than that of a corporate bond or stripped
instrument having similar cash flow characteristics.
 
                         DESCRIPTION OF THE SECURITIES
 
GENERAL
 
     The Securities will be issued in Series. Each Series of Certificates will
be issued pursuant to separate Pooling and Servicing Agreements among the
Depositor, the Master Servicer and the Trustee for the related Series identified
in the related Prospectus Supplement. Each Series of Notes will be issued
pursuant to separate Indentures between the related Issuer and the Trustee for
the related Series identified in the related Prospectus Supplement. The Trust
Fund for each Series of Notes will be created pursuant to an Owner Trust
Agreement between the Depositor and the Owner Trustee. The following summaries
describe certain provisions common to each Series. The summaries do not purport
to be complete and are subject to, and are qualified in their entirety by
reference to, the provisions of the Agreements and the Prospectus Supplement
relating to each Series. When
 
                                       11
 

<PAGE>

<PAGE>
particular provisions or terms used in each Agreement are referred to, such
provisions or terms shall be as specified in such Agreement.
 
     Each Series will consist of one or more Classes, one or more of which may
consist of Compound Interest Securities, Floating Interest Securities, Interest
Weighted Securities or Principal Weighted Securities. A Series may also include
one or more Classes of Subordinate Securities. Unless otherwise specified in the
related Prospectus Supplement, a Class of Subordinate Securities will be offered
hereby or by such Prospectus Supplement only if rated by a Rating Agency in at
least its fourth highest applicable rating category. If so specified in the
related Prospectus Supplement, the Mortgage Assets in a Trust Fund may be
divided into multiple Asset Groups and the Securities of each separate Class
will evidence beneficial ownership of, or be secured by, each corresponding
Asset Group.
 
     The Securities for each Series will be issued in fully registered form, in
the minimum original principal amount, notional amount or percentage interest
specified in the related Prospectus Supplement. The transfer of the Securities
may be registered, and the Securities may be exchanged, without the payment of
any service charge payable in connection with such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or governmental charge that may be imposed in connection with any transfer
or exchange of Securities. If specified in the related Prospectus Supplement,
one or more Classes of a Series may be available in book-entry form only.
 
DISTRIBUTIONS ON THE SECURITIES
 
     General. Commencing on the date specified in the related Prospectus
Supplement, distributions of principal and interest on the Securities will be
made on each Distribution Date to the extent of the 'Available Distribution
Amount' as set forth in the related Prospectus Supplement.
 
     Distributions of interest on Securities which receive interest will be made
periodically at the intervals and at the Security Interest Rate specified or,
with respect to Floating Interest Securities, determined in the manner described
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
unless otherwise specified in the related Prospectus Supplement.
 
     Distributions of principal of and interest on Securities of a Series will
be made by check mailed to Securityholders of such Series registered as such on
the close of business on the record date specified in the related Prospectus
Supplement at their addresses appearing on the security register (the 'Security
Register'), except that (a) distributions may be made by wire transfer in
certain circumstances described in the related Prospectus Supplement and (b) the
final distribution in retirement of a Security will be made only upon
presentation and surrender of such Security at the corporate trust office of the
Trustee for such Series or such other office of the Trustee as specified in the
Prospectus Supplement. If specified in the related Prospectus Supplement, the
Securities of a Series or certain Classes of a Series may be available only in
book-entry form. See 'Book-Entry Registration' herein. With respect to each
Series of Certificates or Notes, the Security Register will be referred to as
the 'Certificate Register' or 'Note Register,' respectively.
 
     With respect to reports to be furnished to Securityholders concerning a
distribution, see 'The Agreements -- Reports to Securityholders.'
 
     Single Class Series. With respect to a Series other than a Multiple Class
Series, distributions on the Securities on each Distribution Date will generally
be allocated to each Security entitled thereto on the basis of the undivided
percentage interest (the 'Percentage Interest') evidenced by such Security in
the Trust Fund or on the basis of their outstanding principal amounts or
notional amounts. If the Mortgage Assets for a Series have adjustable or
variable interest or pass-through rates, then the Security Interest Rate of the
Securities of such Series may also vary, due to changes in such rates and due to
prepayments with respect to Loans comprising or underlying the related Mortgage
Assets. If the Mortgage Assets for a Series have fixed interest or pass-through
rates, then the Security Interest Rate on the Securities of the related Series
may be fixed, or may vary, to the extent prepayments cause changes in the
weighted average interest rate or pass-through rate of the Mortgage Assets. If
the Mortgage Assets have lifetime or periodic adjustment caps on their
respective pass-through rates, then the Security Interest Rate on the Securities
of the related Series may also reflect such caps.
 
                                       12

<PAGE>
     Multiple Class Series. Each Security of a Multiple Class Series will have a
principal amount or a notional amount and a specified Security Interest Rate
(which may be zero). Interest distributions on a Multiple Class Series will be
made on each Security entitled to an interest distribution on each Distribution
Date at the Security Interest Rate specified or, with respect to Floating
Interest Securities, determined as described in the related Prospectus
Supplement, to the extent funds are available in the Certificate Account,
subject to any subordination of the rights of any Subordinate Securities to
receive current distributions. See 'Subordinate Securities' below and 'Credit
Support.'
 
     Interest on all Securities of a Multiple Class Series currently entitled to
receive interest will be distributed on the Distribution Date specified in the
related Prospectus Supplement, to the extent funds are available in the
Certificate Account, subject to any subordination of the rights of any
Subordinate Class to receive current distributions. See 'Subordinate Securities'
below and 'Credit Support.' Distributions of interest on a Class of Compound
Interest Securities will commence only after the related Accrual Termination
Date specified in the related Prospectus Supplement. On each Distribution Date
prior to and including the Accrual Termination Date, interest on such Class of
Compound Interest Securities will accrue and the amount of interest accrued on
such Distribution Date will be added to the principal balance thereof on the
related Distribution Date. On each Distribution Date after the Accrual
Termination Date, interest distributions will be made on Classes of Compound
Interest Securities on the basis of the current Compound Value of such Class.
The Compound Value of a Class of Compound Interest Securities equals the initial
aggregate principal balance of the Class, plus accrued and undistributed
interest added to such Class through the immediately preceding Distribution
Date, less any principal distributions previously made in reduction of the
aggregate outstanding principal balance of such Class.
 
     To the extent provided in the related Prospectus Supplement, the Securities
of a Multiple Class Series may include one or more Classes of Floating Interest
Securities. The Security Interest Rate of a Floating Interest Security will be a
variable or adjustable rate, subject to a Maximum Floating Rate, Minimum
Floating Rate, or both. For each Class of Floating Interest Securities, the
related Prospectus Supplement will set forth the initial Floating Rate (or the
method of determining it), the Floating Interest Period, and the formula, index,
or other method by which the Floating Rate for each Floating Interest Period
will be determined.
 
     If so specified in the related Prospectus Supplement, a Series may include
one or more Classes of Interest Weighted Securities, Principal Weighted
Securities, or both. Unless otherwise specified in the Prospectus Supplement,
payments received from the Mortgage Assets will be allocated on the basis of the
Percentage Interest of each Class in the principal component of such
distributions, the interest component of such distributions, or both, and will
be further allocated on a pro rata basis among the Securities within each Class.
The method or formula for determining the Percentage Interest of a Security will
be set forth in the related Prospectus Supplement.
 
     In the case of a Multiple Class Series, 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
of each Class of Securities shall be as set forth in the related Prospectus
Supplement. A Multiple Class Series may contain two or more classes of
Securities 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 (including 'planned amortization classes' and 'targeted
amortization classes'), or on the basis of collections from designated portions
of the Trust Fund.
 
     Subordinate Securities. One or more Classes of a Series may consist of
Subordinate Securities. Subordinate Securities may be included in a Series to
provide credit support as described herein under 'Credit Support' in lieu of or
in addition to other forms of credit support. The extent of subordination of a
Class of Subordinate Securities may be limited as described in the related
Prospectus Supplement. See 'Credit Support.' If the Mortgage Assets are divided
into separate Asset Groups, beneficial ownership of which is evidenced by
separate Classes of a Series, credit support may be provided by a cross-support
feature which requires that distributions be made to Senior Securities
evidencing beneficial ownership of one Asset Group prior to making distributions
on Subordinate Securities evidencing a beneficial ownership interest in another
Asset Group within the Trust Fund. Subordinate Securities will not be offered
hereby or by such related Prospectus Supplement unless they are rated in one of
the four highest rating categories by at least one Rating Agency. With respect
to any Series of Notes, the Equity Certificates, insofar as they represent the
beneficial ownership interest in the Issuer, will be subordinate to the related
Notes.

FUNDING ACCOUNT
 
     If so specified in the related Prospectus Supplement, the related Agreement
may provide for the transfer by the Seller of additional Loans to the related
Trust Fund after the Closing Date. Such additional Loans will be required to
conform to the requirements set forth in the related Agreement or other
agreement providing for such transfer. As specified in the related Prospectus
Supplement, such transfer may be funded by the establishment of a Funding
Account (a 'Funding Account'). If a Funding Account is established, all or a
portion of the proceeds of the sale of one or more Classes of Securities of the
related Series or a portion of collections on the Loans in respect of principal
will be deposited in such account to be released as additional Loans are
transferred. Unless otherwise specified in the related Prospectus Supplement,
all amounts deposited in a Funding Account will be required to be invested in
Eligible Investments and the amount held therein shall at no time exceed 25% of
the aggregate outstanding principal balance of the Securities. Unless otherwise
specified in the related Prospectus Supplement, the related Agreement or other
agreement providing for the transfer of additional Loans will provide that all
such transfers must be made within 3 months after the Closing Date, and that
amounts set aside to fund such transfers (whether in a Funding Account or
otherwise) and not so applied within the required period of time will be deemed
to be principal prepayments and applied in the manner set forth in such
Prospectus Supplement. A Funding Account can affect the application of the
requirements under ERISA. See 'ERISA Considerations.'
 
OPTIONAL TERMINATION
 
     If so specified in the related Prospectus Supplement for a Series, the
Depositor, the Master Servicer, or another entity designated in the related
Prospectus Supplement may, at its option, cause an early termination of a Trust
Fund by repurchasing all of the Mortgage Assets from such Trust Fund on or after
a date specified in the related Prospectus Supplement, or on or after such time
as the aggregate outstanding principal amount of the Mortgage Assets is less
than a specified percentage of their initial aggregate principal amount. In the
case of a Trust Fund for which a REMIC election or elections have been made, the
Trustee shall receive a satisfactory opinion of counsel that the repurchase
price will not jeopardize the REMIC status of the REMIC or REMICs and that the
optional termination will be conducted so as to constitute a 'qualified
liquidation' under Section 860F of the Code. See 'The
Agreements -- Termination.'
 
BOOK-ENTRY REGISTRATION
 
     If so specified in the related Prospectus Supplement, the Securities will
be issued in book-entry form in the minimum denominations specified in such
Prospectus Supplement and integral multiples thereof, and each Class will be
represented by a single Security registered in the name of the nominee of the
depository, The Depository Trust Company ('DTC'), a limited-purpose trust
company organized under the laws of the State of New York. If so specified in
the related Prospectus Supplement, no person acquiring an interest in the
Securities (a 'Securityowner') will be entitled to receive a Security issued in
fully registered, certificated form (a 'Definitive Security') representing such
person's interest in the Securities except in the event that the book-entry
system for the Securities is discontinued (as described below). Unless and until
Definitive Securities are issued, it is anticipated that the only Securityholder
of the Securities will be Cede & Co., as nominee of DTC. Securityowners will not
be registered 'Securityholders' or registered 'Holders' under the related
Agreement, and Securityowners will only be permitted to exercise the rights of
Securityholders indirectly through DTC Participants. With respect to each Series
of Certificates or Notes, Securityowners and Securityholders will be referred to
as 'Certificateowners' and 'Certificateholders' or 'Noteowners' and
'Noteholders', respectively.
 
     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
accounts of its Participants. 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 entities that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly ('Indirect Participants').
 
     Securityowners that are not Participants or Indirect Participants but
desire to purchase, sell or otherwise transfer ownership of Securities may do so
only though Participants and Indirect Participants. Because DTC can only act on
behalf of Participants and Indirect Participants, the ability of a Securityowner
to pledge such owner's
 
                                       14
 

<PAGE>

<PAGE>
Security to persons or entities that do not participate in the DTC system, or
otherwise take actions in respect of such Security, may be limited. In addition,
under a book-entry format, Securityowners may experience some delay in their
receipt of principal and interest distributions with respect to the Securities
since such distributions will be forwarded to DTC and DTC will then forward such
distributions to its Participants which in turn will forward them to Indirect
Participants or Securityowners.
 
     Under the rules, regulations and procedures creating and affecting DTC and
its operations (the 'Rules'), DTC Participants may make book-entry transfers
among Participants through DTC facilities with respect to the Securities and
DTC, as registered holder, is required to receive and transmit principal and
interest distributions and distributions with respect to the Securities.
Participants and Indirect Participants with which Securityowners have accounts
with respect to Securities similarly are required to make book-entry transfers
and receive and transmit such distributions on behalf of their respective
Securityowners. Accordingly, although Securityowners will not possess
certificates or notes, the Rules provide a mechanism by which Securityowners
will receive distributions and will be able to transfer their interests.
 
     The Depositor understands that DTC will take any action permitted to be
taken by a Securityholder under the related Agreement only at the direction of
one or more Participants to whose account with DTC the Securities are credited.
Additionally, the Depositor understands that DTC will take such actions with
respect to holders of a certain specified interest in the certificates or notes
or holders having a certain specified voting interest only at the direction of
and on behalf of Participants whose holdings represent that specified interest
or voting interest. DTC may take conflicting actions with respect to other
Holders of Securities to the extent that such actions are taken on behalf of
Participants whose holdings represent that specified interest or voting
interest.
 
     DTC may discontinue providing its services as securities depository with
respect to the Securities at any time by giving reasonable notice to the
Depositor or the Trustee. Under such circumstances, in the event that a
successor securities depository is not obtained, Definitive Securities will be
printed and delivered. In addition, the Depositor may at its option elect to
discontinue use of the book-entry system through DTC. In that event, too,
Definitive Securities will be printed and delivered.
 
                 YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS
 
PAYMENT DELAYS
 
     With respect to any Series, a period of time will elapse between receipt of
payments or distributions on the Mortgage Assets and the Distribution Date on
which such payments or distributions are passed through to Securityholders. Such
a delay will effectively reduce the yield that would otherwise be obtained if
payments or distributions were distributed on or near the date of receipt. The
related Prospectus Supplement may set forth an example of the timing of receipts
and the distribution thereof to Securityholders.
 
PRINCIPAL PREPAYMENTS
 
     With respect to a Series for which the Mortgage Assets consist of Loans or
participation interests therein, when a Loan prepays in full, the borrower will
generally be required to pay interest on the amount of prepayment only to the
prepayment date. In addition, the prepayment may not be required to be passed
through to Securityholders until the month following receipt. The effect of
these provisions is to reduce the aggregate amount of interest which would
otherwise be available for distributions on the Securities, thus effectively
reducing the yield that would be obtained if interest continued to accrue on the
Loan until the date on which the principal prepayment was scheduled to be paid.
To the extent specified in the related Prospectus Supplement, this effect on
yield may be mitigated by, among other things, an adjustment to the servicing
fee otherwise payable to the Master Servicer or Servicer with respect to any
such prepaid Loans. See 'Servicing of Loans -- Advances and Limitations
Thereon.'
 
TIMING OF REDUCTION OF PRINCIPAL BALANCE
 
     A Multiple Class Series may provide that, for purposes of calculating
interest distributions, the principal amount of the Securities is deemed reduced
as of a date prior to the Distribution Date on which principal thereon is
actually distributed. Consequently, the amount of interest accrued during any
Interest Accrual Period
 
                                       15
 

<PAGE>

<PAGE>
will be less than the amount that would have accrued on the actual principal
balance of the Security outstanding. The effect of such provisions is to produce
a lower yield on the Securities than would be obtained if interest were to
accrue on the Securities on the actual unpaid principal amount of such
Securities to each Distribution Date. The related Prospectus Supplement will
specify the time at which the principal amounts of the Securities are determined
or are deemed to reduce for purposes of calculating interest distributions on
Securities of a Multiple Class Series.
 
INTEREST OR PRINCIPAL WEIGHTED SECURITIES
 
     If a Class of Securities consists of Interest Weighted Securities or
Principal Weighted Securities, a lower rate of principal prepayments than
anticipated will negatively affect the yield to investors in Principal Weighted
Securities, and a higher rate of principal prepayments than anticipated will
negatively affect the yield to investors in Interest Weighted Securities. The
Prospectus Supplement for a Series including such Securities will include a
table showing the effect of various levels of prepayment on yields on such
Securities. Such tables will be intended to illustrate the sensitivity of yields
to various prepayment rates and will not be intended to predict, or provide
information which will enable investors to predict, yields or prepayment rates.
 
FUNDING ACCOUNT
 
     If the applicable Agreement for a Series of Securities provides for a
Funding Account or other means of funding the transfer of additional Loans to
the related Trust Fund, as described under 'Description of the
Securities -- Funding Account' herein, and the Trust Fund is unable to acquire
such additional Loans within any applicable time limit, the amounts set aside
for such purpose may be applied as principal payments on one or more Classes of
Securities of such Series. See 'Risk Factors -- Yield, Prepayment and Maturity.'
 
FINAL SCHEDULED DISTRIBUTION DATE
 
     The Final Scheduled Distribution Date of each Class of any Series other
than a Multiple Class Series will be the Distribution Date following the latest
stated maturity of any Mortgage Asset in the related Trust Fund. The Final
Scheduled Distribution Date of each Class of any Multiple Class Series, if
specified in the related Prospectus Supplement, will be the date (calculated on
the basis of the assumptions applicable to such Series described therein) on
which the aggregate principal balance of such Class will be reduced to zero.
Since prepayments on the Loans underlying or comprising the Mortgage Assets will
be used to make distributions in reduction of the outstanding principal amount
of the Securities, it is likely that the actual maturity of any Class will occur
earlier, and may occur substantially earlier, than its Final Scheduled
Distribution Date.
 
PREPAYMENTS AND WEIGHTED AVERAGE LIFE
 
     Weighted average life refers to the average amount of time that will elapse
from the date of issue of a security until each dollar of the principal of such
security will be repaid to the investor. The weighted average life of the
Securities of a Series will be influenced by the rate at which principal on the
Loans comprising or underlying the Mortgage Assets for such Securities is paid,
which may be in the form of scheduled amortization or prepayments (for this
purpose, the term 'prepayment' includes prepayments, in whole or in part, and
liquidations due to default).
 
     The rate of principal prepayments on pools of housing loans is influenced
by a variety of economic, demographic, geographic, legal, tax, social and other
factors. The rate of prepayments of conventional housing loans has fluctuated
significantly in recent years. In general, however, if prevailing mortgage
market interest rates fall significantly below the interest rates on the Loans
comprising or underlying the Mortgage Assets for a Series, such Loans are likely
to prepay at rates higher than if prevailing interest rates remain at or above
the interest rates borne by such Loans. In this regard, it should be noted that
the Loans comprising or underlying the Mortgage Assets of a Series may have
different interest rates, and the stated pass-through or interest rate of
certain Mortgage Assets or the Security Interest Rate on the Securities may be a
number of percentage points less than interest rates on such Loans. In addition,
the weighted average life of the Securities may be affected by the varying
maturities of the Loans comprising or underlying the Mortgage Assets. If any
Loans comprising or underlying the Mortgage Assets for a Series have actual
terms-to-stated maturity of less than those assumed in calculating the Final
Scheduled Distribution Date of the related Securities, one or more Class of the
Series may
 
                                       16
 

<PAGE>

<PAGE>
be fully paid prior to its Final Scheduled Distribution Date, even in the
absence of prepayments and a reinvestment return higher than assumed.
 
     Prepayments on loans are commonly measured relative to a prepayment
standard or model, such as the Constant Prepayment Rate ('CPR') prepayment model
or the Standard Prepayment Assumption ('SPA') prepayment model. CPR represents a
constant assumed rate of prepayment each month relative to the then outstanding
principal balance of a pool of loans for the life of such loans. SPA represents
an assumed rate of prepayment each month relative to the then outstanding
principal balance of a pool of loans. A prepayment assumption of 100% of SPA
assumes prepayment rates of 0.2% per annum of the then outstanding principal
balance of such loans in the first month of the life of the loans and an
additional 0.2% per annum in each month thereafter until the thirtieth month.
Beginning in the thirtieth month and in each month thereafter during the life of
the loans, 100% of SPA assumes a constant prepayment rate of 6% per annum.
 
     Neither CPR or SPA nor any other prepayment model or assumption purports to
be an historical description of prepayment experience or a prediction of the
anticipated rate of prepayment of any pool of loans, including the Loans
underlying or comprising the Mortgage Assets. Thus, it is likely that prepayment
of any Loans comprising or underlying the Mortgage Assets for any Series will
not conform to any level of CPR or SPA.
 
     The Prospectus Supplement for each Multiple Class Series may describe the
prepayment standard or model used to prepare the illustrative tables setting
forth the weighted average life of each Class of such Series under a given set
of prepayment assumptions. The related Prospectus Supplement may also describe
the percentage of the initial principal balance of each Class of such Series
that would be outstanding on specified Distribution Dates for such Series based
on the assumptions stated in such Prospectus Supplement, including assumptions
that prepayments on the Loans comprising or underlying the related Mortgage
Assets are made at rates corresponding to various percentages of CPR, SPA or at
such other rates specified in such Prospectus Supplement. Such tables and
assumptions are intended to illustrate the sensitivity of weighted average life
of the Securities to various prepayment rates and will not be intended to
predict or to provide information which will enable investors to predict the
actual weighted average life of the Securities or prepayment rates of the Loans
comprising or underlying the related Mortgage Assets.
 
OTHER FACTORS AFFECTING WEIGHTED AVERAGE LIFE
 
     Type of Loan. Multifamily Loans may have provisions which prevent
prepayment for a number of years and may provide for payments of interest only
during a certain period followed by amortization of principal on the basis of a
schedule extending beyond the maturity of the related mortgage loan. Additional
Collateral Loans, ARMs, Balloon Loans, Bi-Weekly Loans, GEM Loans, GPM Loans or
Buy-Down Loans comprising or underlying the Mortgage Assets may experience a
rate of principal prepayments which is different from the principal prepayment
rate for Additional Collateral Loans, ARMs, Balloon Loans, Bi-Weekly Loans, GEM
Loans, GPM Loans or Buy-Down Loans included in any other mortgage pool or from
conventional Fixed Rate Loans or from other adjustable rate or graduated equity
mortgages having different characteristics.
 
     In the case of Negatively Amortizing ARMs, if interest rates rise without a
simultaneous increase in the related Scheduled Payment, Deferred Interest and
Negative Amortization may result. However, borrowers may pay amounts in addition
to their Scheduled Payments in order to avoid such Negative Amortization and to
increase tax deductible interest payments. To the extent that any of such
Mortgage Loans negatively amortize over their respective terms, future interest
accruals are computed on the higher outstanding principal balance of such
mortgage loan and a smaller portion of the Scheduled Payment is applied to
principal than would be required to amortize the unpaid principal over its
remaining term. Accordingly, the weighted average life of such Loans will
increase. During a period of declining interest rates, the portion of each
Scheduled Payment in excess of the scheduled interest and principal due will be
applied to reduce the outstanding principal balance of the related Loan, thereby
resulting in accelerated amortization of such Negatively Amortizing ARM. Any
such acceleration in amortization of the principal balance of any Negatively
Amortizing ARM will shorten the weighted average life of such Mortgage Loan. The
application of partial prepayments to reduce the outstanding principal balance
of a Negatively Amortizing ARM will tend to reduce the weighted average life of
the mortgage loan and will adversely affect the yield to Holders who purchased
their Securities at a premium, if any, and Holders of an Interest Weighted
Class. The pooling of Negatively Amortizing ARMs having Rate Adjustment Dates in
different months, together with different initial Mortgage Rates, Maximum
Mortgage Rates, Minimum Mortgage Rates and stated maturity dates, could result
in some Negatively Amortizing ARMs
 
                                       17

<PAGE>
which comprise or underlie the Mortgage Assets experiencing negative
amortization while the amortization of other Negatively Amortizing ARMs may be
accelerated.
 
     If the Loans comprising or underlying the Mortgage Assets for a Series
include ARMs that permit the borrower to convert to a long-term fixed interest
rate loan, the Master Servicer, the Servicer, the applicable Seller, the PMBS
Servicer or another party, as applicable, may, if specified in the related
Prospectus Supplement, be obligated to repurchase any Loan so converted. Any
such conversion and repurchase would reduce the average weighted life of the
Securities of the related Series.
 
     Because of the payment terms of Balloon Loans, there is a risk that such
Mortgage Loans, including Multifamily Loans and Additional Collateral Loans,
that require Balloon Payments may default at maturity, or that the maturity of
such Mortgage Loans may be extended in connection with a workout. With respect
to Balloon Loans, payment of the Balloon Payment (which, based on the
amortization schedule of such Mortgage Loans, is expected to be the entire or a
substantial amount of the original principal balance) will generally depend on
the Mortgagor's ability to obtain refinancing of such Mortgage Loans, to sell
the Mortgaged Property prior to the maturity of the Balloon Loan or to otherwise
have sufficient funds to pay such Balloon Payment. 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 market 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, none of the Depositor, the Master Servicer, or
any of their affiliates will be obligated to refinance or repurchase any
Mortgage Loan or to sell the Mortgaged Property.
 
     A GEM Loan provides for scheduled annual increases in the borrower's
Scheduled Payment. Because the additional portion of the Scheduled Payment is
applied to reduce the unpaid principal balance of the GEM Loan, the stated
maturity of a GEM Loan will be significantly shorter than the 25 to 30 year term
used as the basis for calculating the installments of principal and interest
applicable until the first adjustment date.
 
     The prepayment experience with respect to Manufactured Home Loans will
generally not correspond to the prepayment experience on other types of housing
loans.
 
     Foreclosures and Payment Plans. The number of foreclosures and the
principal amount of the Loans comprising or underlying the Mortgage Assets which
are foreclosed in relation to the number of Loans which are repaid in accordance
with their terms will affect the weighted average life of the Loans comprising
or underlying the Mortgage Assets and that of the related Series of Securities.
Servicing decisions made with respect to the Loans, including the use of payment
plans prior to a demand for acceleration and the restructuring of Loans in
bankruptcy proceedings, may also have an impact upon the payment patterns of
particular Loans. In particular, the return to Holders of Securities who
purchased their Securities at a premium, if any, and the yield on an Interest
Weighted Class may be adversely affected by servicing policies and decisions
relating to foreclosures.
 
     Due on Sale Clauses. The acceleration of prepayment as a result of certain
transfers of the Mortgaged Property securing a Loan is another factor affecting
prepayment rates. Whereas FHA Loans are assumable by a purchaser of the
underlying mortgaged property, the Loans constituting or underlying the Mortgage
Assets may include 'due-on-sale' clauses. Except as otherwise described in the
Prospectus Supplement for a Series, the PMBS Servicer of Loans underlying
Private Mortgage-Backed Securities and the Master Servicer or the Servicer of
Loans constituting or underlying the Mortgage Assets for a Series will be
required, to the extent it knows of any conveyance or prospective conveyance of
the related residence by any borrower, to enforce any 'due-on-sale' clause
applicable to the related Loan under the circumstances and in the manner it
enforces such clauses with respect to other similar loans in its portfolio.
Certain of the Multifamily Loans in a Trust Fund may also contain a
due-on-encumbrance clause that entitles the lender to accelerate the maturity of
the Mortgage Loan upon the creation of any other lien or encumbrance upon the
Mortgaged Property. FHA Loans and VA Loans are not permitted to contain
'due-on-sale' clauses and are freely assumable by qualified persons. However, as
homeowners move or default on their housing loans, the Mortgaged Property is
generally sold and the loans prepaid, even though, by their terms, the loans are
not 'due-on-sale' and could have been assumed by new buyers.

     Optional Termination. If so specified in the related Prospectus Supplement,
the entity specified therein may cause an early termination of the related Trust
Fund by its repurchase of the remaining Mortgage Assets therein. See
'Description of the Securities -- Optional Termination.'
 
                                THE TRUST FUNDS
 
GENERAL
 
     The Trust Fund for each Series will be held by the Trustee for the benefit
of the related Securityholders. Each Trust Fund will consist of (a) the Mortgage
Assets; (b) amounts held from time to time in the Collection Account and the
Certificate Account established for such Series; (c) Mortgaged Property which
secured a Loan and which is acquired on behalf of the Securityholders by
foreclosure, deed in lieu of foreclosure or repossession and certain proceeds
from the disposition of any related Additional Collateral; (d) any reserve fund
for such Series, if specified in the related Prospectus Supplement; (e) the
Sub-Servicing Agreements, if any, relating to Loans in the Trust Fund; (f) any
primary mortgage insurance policies relating to Loans in the Trust Fund; (g) any
pool insurance policy, any special hazard insurance policy, any bankruptcy bond
or other credit support relating to the Series; (h) investments held in any fund
or account or any Guaranteed Investment Contract and, if so specified in the
Prospectus Supplement, income from the reinvestment of such funds; and (i) any
other instrument or agreement relating to the Trust Fund and specified in the
related Prospectus Supplement (which may include an interest rate swap agreement
or an interest rate cap agreement or similar agreement issued by a bank,
insurance company or savings and loan association); provided, that if so
specified in the related Prospectus Supplement, certain of the items listed
above may be held outside of the Trust Fund.
 
     To the extent specified in the related Prospectus Supplement, certain
amounts ('Retained Interests') which are received with respect to a Private
Mortgage-Backed Security or Loan comprising the Mortgage Assets for a Series
will not be included in the Trust Fund for such Series, but will be retained by
or payable to the originator, Servicer or seller of such Private Mortgage-Backed
Security or Loan, free and clear of the interest of Securityholders under the
related Agreement.
 
     Mortgage Assets in the Trust Fund for a Series may consist of any
combination of the following to the extent and as specified in the related
Prospectus Supplement: (a) Private Mortgage-Backed Securities, (b) Mortgage
Loans or participation interests therein and Manufactured Home Loans or
participation interests therein or (c) Agency Securities. Loans which comprise
the Mortgage Assets will be purchased by the Depositor directly or through an
affiliate in the open market or in privately negotiated transactions from the
Seller. Some of the Loans may have been originated by an affiliate of the
Depositor. Participation interests in Loans may be purchased by the Depositor,
or an affiliate, pursuant to a participation agreement. See 'The Agreements --
Assignment of Mortgage Assets.'
 
PRIVATE MORTGAGE-BACKED SECURITIES
 
     General. Private Mortgage-Backed Securities may consist of (a) mortgage
pass-through certificates, evidencing an undivided interest in a pool of Loans,
(b) collateralized mortgage obligations secured by Loans or (c) pass-through
certificates representing beneficial interests in Agency Securities. Private
Mortgage-Backed Securities will have been issued pursuant to a pooling and
servicing agreement, an indenture or similar agreement (a 'PMBS Agreement'). The
seller/servicer of the underlying Loans will have entered into the PMBS
Agreement with the trustee under such PMBS Agreement (the 'PMBS Trustee'). The
PMBS Trustee or its agent, or a custodian, will possess the Loans underlying
such Private Mortgage-Backed Security. Loans underlying a Private
Mortgage-Backed Security will be serviced by a servicer (the 'PMBS Servicer')
directly or by one or more subservicers who may be subject to the supervision of
the PMBS Servicer. The PMBS Servicer will be a FNMA- or FHLMC-approved servicer
and, if FHA Loans underlie the Private Mortgage-Backed Securities, approved by
HUD as a FHA mortgagee.
 
     The issuer of the Private Mortgage-Backed Securities (the 'PMBS Issuer')
will be a financial institution or other entity engaged generally in the
business of mortgage lending, a public agency or instrumentality of a state,
local or federal government, or a limited purpose corporation organized for the
purpose of, among other things, establishing trusts and acquiring and selling
housing loans to such trusts, and selling beneficial interests in such trusts.
If so specified in the Prospectus Supplement, the PMBS Issuer may be the
Depositor or an affiliate of the Depositor. The obligations of the PMBS Issuer
will generally be limited to certain representations and
 
                                       19
 

<PAGE>

<PAGE>
warranties with respect to the assets conveyed by it to the related trust.
Unless otherwise specified in the related Prospectus Supplement, the PMBS Issuer
will not have guaranteed any of the assets conveyed to the related trust or any
of the Private Mortgage-Backed Securities issued under the PMBS Agreement.
Additionally, although the Loans underlying the Private Mortgage-Backed
Securities may be guaranteed by an agency or instrumentality of the United
States, the Private Mortgage-Backed Securities themselves will not be so
guaranteed.
 
     Distributions of principal and interest will be made on the Private
Mortgage-Backed Securities on the dates specified in the related Prospectus
Supplement. The Private Mortgage-Backed Securities may be entitled to receive
nominal or no principal distributions or nominal or no interest distributions.
Principal and interest distributions will be made on the Private Mortgage-Backed
Securities by the PMBS Trustee or the PMBS Servicer. The PMBS Issuer or the PMBS
Servicer may have the right to repurchase assets underlying the Private
Mortgage-Backed Securities after a certain date or under other circumstances
specified in the related Prospectus Supplement.
 
     Underlying Loans. The Loans underlying the Private Mortgage-Backed
Securities may consist of fixed rate, level payment, fully amortizing Loans or
Additional Collateral Loans, GEM Loans, GPM Loans, Balloon Loans, Buy-Down
Loans, Bi-Weekly Loans, ARMs, or Loans having other special payment features.
Loans may be secured by Single Family Property, Multifamily Property,
Manufactured Homes, or, in the case of Cooperative Loans, by an assignment of
the proprietary lease or occupancy agreement relating to a Cooperative Dwelling
and the shares issued by the related cooperative. Except as otherwise specified
in the related Prospectus Supplement, (i) no Loan will have had a Loan-to-Value
Ratio at origination in excess of 95%, (ii) each Mortgage Loan secured by Single
Family Property and having a Loan-to-Value Ratio in excess of 80% at origination
will be covered by a primary mortgage insurance policy, (iii) each Loan will
have had an original term to stated maturity of not less than 10 years and not
more than 40 years, (iv) no Loan that was more than 30 days delinquent as to the
payment of principal or interest will have been eligible for inclusion in the
assets under the related PMBS Agreement, (v) each Loan (other than a Cooperative
Loan) will be required to be covered by a standard hazard insurance policy
(which may be a blanket policy), and (vi) each Loan (other than a Cooperative
Loan or a Loan secured by a Manufactured Home) will be covered by a title
insurance policy.
 
     Credit Support Relating to Private Mortgage-Backed Securities. Credit
support in the form of reserve funds, subordination of other private mortgage
certificates issued under the PMBS Agreement, overcollateralization, letters of
credit, insurance policies or other types of credit support may be provided with
respect to the Loans underlying the Private Mortgage-Backed Securities or with
respect to the Private Mortgage-Backed Securities themselves. The type,
characteristics and amount of credit support, if any, will be a function of
certain characteristics of the Loans and other factors and will have been
established for the Private Mortgage-Backed Securities on the basis of
requirements of the rating agencies which initially assigned a rating to the
Private Mortgage-Backed Securities.
 
     Additional Information. The Prospectus Supplement for a Series for which
the Trust Fund includes Private Mortgage-Backed Securities will specify (i) the
aggregate approximate principal amount and type of the Private Mortgage-Backed
Securities to be included in the Trust Fund, (ii) certain characteristics of the
Loans which comprise the underlying assets for the Private Mortgage-Backed
Securities including (A) the payment features of such Loans (i.e., whether they
are fixed rate or adjustable rate and whether they provide for fixed level
payments or other payment features), (B) the approximate aggregate principal
balance, if known, of underlying Loans insured or guaranteed by a governmental
entity, (C) the servicing fee or range of servicing fees with respect to the
Loans, and (D) the minimum and maximum stated maturities of the underlying Loans
at origination, (iii) the maximum original term-to-stated maturity of the
Private Mortgage-Backed Securities, (iv) the weighted average term-to-stated
maturity of the Private Mortgage-Backed Securities, (v) the note interest rate,
pass-through or certificate rate or ranges thereof for the Private
Mortgage-Backed Securities, (vi) the weighted average note interest rate,
pass-through or certificate rate of the Private Mortgage-Backed Securities,
(vii) the PMBS Issuer, the PMBS Servicer (if other than the PMBS Issuer) and the
PMBS Trustee for such Private Mortgage-Backed Securities, (viii) certain
characteristics of credit support, if any, such as reserve funds, insurance
policies, letters of credit or guarantees relating to the Loans underlying the
Private Mortgage-Backed Securities or to such Private Mortgage-Backed Securities
themselves, (ix) the terms on which the underlying Loans for such Private
Mortgage-Backed Securities may, or are required to, be purchased prior to their
stated maturity or the stated maturity of the Private Mortgage-Backed Securities
and (x) the terms on which Loans may be substituted for those originally
underlying the Private Mortgage-Backed Securities.

THE AGENCY SECURITIES
 
     All of the Agency Securities will be registered in the name of the Trustee
or its nominee or, in the case of Agency Securities issued only in book-entry
form, a financial intermediary (which may be the Trustee) that is a member of
the Federal Reserve System or of a clearing corporation on the books of which
the security is held. Each Agency Security will evidence an interest in a pool
of mortgage loans and/or cooperative loans and/or in principal distributions and
interest distributions thereon.
 
     The descriptions of GNMA, FHLMC and FNMA Certificates that are set forth
below are descriptions of certificates representing proportionate interests in a
pool of mortgage loans and in the payments of principal and interest thereon.
GNMA, FHLMC or FNMA may also issue mortgage-backed securities representing a
right to receive distributions of interest only or principal only or
disproportionate distributions of principal or interest or to receive
distributions of principal and/or interest prior or subsequent to distributions
on other certificates representing interests in the same pool of mortgage loans.
In addition, any of such issuers may issue certificates representing interests
in mortgage loans having characteristics that are different from the types of
mortgage loans described below. The terms of any such certificates to be
included in a Trust Fund (and of the underlying mortgage loans) will be
described in the related Prospectus Supplement, and the descriptions that follow
are subject to modification as appropriate to reflect the terms of any such
certificates that are actually included in a Trust Fund.
 
     GNMA. GNMA is a wholly-owned corporate instrumentality of the United States
within HUD. Section 306(g) of Title III of the National Housing Act of 1934, as
amended (the 'Housing Act'), authorizes GNMA to guarantee the timely payment of
the principal of and interest on certificates representing interests in a pool
of mortgages (i) insured by the FHA, under the Housing Act or under Title V of
the Housing Act of 1949, or (ii) partially guaranteed by the VA under the
Servicemen's Readjustment Act of 1944, as amended, or under Chapter 37 of Title
38, United States Code.
 
     Section 306(g) of the Housing Act provides that 'the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guarantee under this subsection.' In order to meet
its obligations under any such guarantee, GNMA may, under Section 306(d) of the
Housing Act, borrow from the United States Treasury an amount that is at any
time sufficient to enable GNMA to perform its obligations under its guarantee.
See 'Additional Information' for the availability of further information
regarding GNMA and GNMA Certificates.
 
     GNMA Certificates. Unless otherwise specified in the related Prospectus
Supplement, each GNMA Certificate relating to a Series (which may be a 'GNMA I
Certificate' or a 'GNMA II Certificate' as referred to by GNMA) will be a 'fully
modified pass-through' mortgage-backed certificate issued and serviced by a
mortgage banking company or other financial concern approved by GNMA, except
with respect to any stripped mortgage-backed securities guaranteed by GNMA or
any REMIC securities issued by GNMA. The characteristics of any GNMA
Certificates included in the Trust Fund for a Series of Certificates will be set
forth in the related Prospectus Supplement.
 
     FHLMC. FHLMC is a corporate instrumentality of the United States created
pursuant to Title III of the Emergency Home Finance Act of 1970, as amended (the
'FHLMC Act'). FHLMC was established primarily for the purpose of increasing the
availability of mortgage credit for the financing of needed housing. The
principal activity of FHLMC currently consists of purchasing first-lien,
conventional, residential mortgage loans or participation interests in such
mortgage loans and reselling the mortgage loans so purchased in the form of
guaranteed mortgage securities, primarily FHLMC Certificates. In 1981, FHLMC
initiated its Home Mortgage Guaranty Program under which it purchases mortgage
loans from sellers with FHLMC Certificates representing interests in the
mortgage loans so purchased. All mortgage loans purchased by FHLMC must meet
certain standards set forth in the FHLMC Act. FHLMC is confined to purchasing,
so far as practicable, mortgage loans that it deems to be of such quality and
type as to meet generally the purchase standards imposed by private
institutional mortgage investors. See 'Additional Information' for the
availability of further information regarding FHLMC and FHLMC Certificates.
Neither the United States nor any agency thereof is obligated to finance FHLMC's
operations or to assist FHLMC in any other manner.
 
     FHLMC Certificates. Unless otherwise specified in the related Prospectus
Supplement, each FHLMC Certificate relating to a Series will represent an
undivided interest in a pool of mortgage loans that typically
 
                                       21
 

<PAGE>

<PAGE>
consists of conventional loans (but may include FHA Loans and VA Loans)
purchased by FHLMC, except with respect to any stripped mortgage-backed
securities issued by FHLMC. Each such pool will consist of mortgage loans (i)
substantially all of which are secured by one- to four-family residential
properties or (ii) if specified in the related Prospectus Supplement, are
secured by five or more family residential properties. The characteristics of
any FHLMC Certificates included in the Trust Fund for a Series of Certificates
will be set forth in the related Prospectus Supplement.
 
     FNMA. FNMA is a federally chartered and privately owned corporation
organized and existing under the Federal National Mortgage Association Charter
Act (12 U.S.C. 'SS' 1716 et seq.). It is the nation's largest supplier of
residential mortgage funds. FNMA was originally established in 1938 as a United
States government agency to provide supplemental liquidity to the mortgage
market and was transformed into a stockholder-owned and privately managed
corporation by legislation enacted in 1968. FNMA provides funds to the mortgage
market primarily by purchasing home mortgage loans from local lenders, thereby
replenishing their funds for additional lending. See 'Additional Information'
for the availability of further information respecting FNMA and FNMA
Certificates. Although the Secretary of the Treasury of the United States has
authority to lend FNMA up to $2.25 billion outstanding at any time, neither the
United States nor any agency thereof is obligated to finance FNMA's operations
or to assist FNMA in any other manner.
 
     FNMA Certificates. Unless otherwise specified in the related Prospectus
Supplement, each FNMA Certificate relating to a Series will represent a
fractional undivided interest in a pool of mortgage loans formed by FNMA, except
with respect to any stripped mortgage-backed securities issued by FNMA. Mortgage
loans underlying FNMA Certificates will consist of (i) fixed, variable or
adjustable rate conventional mortgage loans or (ii) fixed-rate FHA Loans or VA
Loans. Such mortgage loans may be secured by either one- to four-family or
multi-family residential properties. The characteristics of any FNMA
Certificates included in the Trust Fund for a Series of Certificates will be set
forth in the related Prospectus Supplement.
 
THE MORTGAGE LOANS
 
     The Trust Fund for a Series may consist of Mortgage Loans or participation
interests therein. Mortgage Loans comprising the Mortgage Assets and Mortgage
Loans in which participation interests are conveyed to the Trustee are both
referred to herein as the 'Mortgage Loans.' If so specified in the related
Prospectus Supplement, the Mortgage Loans will have been originated by mortgage
lenders which are FNMA- or FHLMC-approved seller/servicers or by their
wholly-owned subsidiaries, and, in the case of FHA Loans, approved by HUD as an
FHA mortgagee. Some of the Mortgage Loans may have been originated by an
affiliate of the Depositor. The Mortgage Loans may include Conventional Loans,
FHA Loans or VA Loans. The Mortgage Loans may have fixed interest rates or
adjustable interest rates and may provide for fixed level payments or may be
Additional Collateral Loans, GPM Loans, GEM Loans, Balloon Loans, Buy-Down
Loans, Bi-Weekly Loans or Mortgage Loans with other payment characteristics as
described below and under 'Yield, Prepayment and Maturity Considerations' herein
or in the related Prospectus Supplement. ARMs may have a feature which permits
the borrower to convert the rate thereon to a long-term fixed rate. The Mortgage
Loans may be secured by mortgages or deeds of trust or other similar security
instruments creating a first lien or a junior lien on Mortgaged Property. The
Mortgage Loans may also include Cooperative Loans evidenced by promissory notes
secured by a lien on the shares issued by private, non-profit, cooperative
housing corporations and on the related proprietary leases or occupancy
agreements granting exclusive rights to occupy specific Cooperative Dwellings.
The Mortgage Loans may also include Condominium Loans secured by a Mortgage on a
Condominium Unit together with such Condominium Unit's appurtenant interest in
the common elements.
 
     The Mortgaged Properties may include Single Family Property (i.e., one- to
four-family residential housing, including Condominium Units, and Cooperative
Dwellings) or Multifamily Property (i.e., multifamily residential rental
properties or cooperatively-owned properties consisting of five or more dwelling
units). The Mortgaged Properties may consist of detached individual dwellings,
individual condominiums, townhouses, duplexes, row houses, individual units in
planned unit developments and other attached dwelling units. Multifamily
Property may include mixed commercial and residential structures. Each Single
Family Property and Multifamily Property will be located on land owned in fee
simple by the borrower or on land leased by the borrower. The fee interest in
any leased land will be subject to the lien securing the related Mortgage Loan.
Attached dwellings may include owner-occupied structures where each borrower
owns the land upon which the unit is built, with the remaining adjacent land
owned in common or dwelling units subject to a proprietary lease
 
                                       22
 

<PAGE>

<PAGE>
or occupancy agreement in a cooperatively owned apartment building. The
proprietary lease or occupancy agreement securing a Cooperative Loan is
generally subordinate to any blanket mortgage on the related cooperative
apartment building and/or on the underlying land. Additionally, in the case of a
Cooperative Loan, the proprietary lease or occupancy agreement is subject to
termination and the cooperative shares are subject to cancellation by the
cooperative if the tenant-stockholder fails to pay maintenance or other
obligations or charges owed by such tenant-stockholder. See 'Certain Legal
Aspects of Loans.'
 
     If specified in the related Prospectus Supplement, certain of the mortgage
pools may contain Mortgage Loans secured by junior liens, and the related senior
liens ('Senior Liens') may not be included in the mortgage pool. The primary
risk to holders of Mortgage Loans secured by junior liens is the possibility
that adequate funds will not be received in connection with a foreclosure of the
related Senior Liens to satisfy fully both the Senior Liens and the Mortgage
Loan. In the event that a holder of a Senior Lien forecloses on a Mortgaged
Property, the proceeds of the foreclosure or similar sale will be applied first
to the payment of court costs and fees in connection with the foreclosure,
second to real estate taxes, third in satisfaction of all principal, interest,
prepayment or acceleration penalties, if any, and any other sums due and owing
to the holder of the Senior Liens. The claims of the holders of the Senior Liens
will be satisfied in full out of proceeds of the liquidation of the Mortgage
Loan, if such proceeds are sufficient, before the Trust Fund as holder of the
junior lien receives any payments in respect of the Mortgage Loan. If the Master
Servicer were to foreclose on any Mortgage Loan, it would do so subject to any
related Senior Liens. In order for the debt related to the Mortgage Loan to be
paid in full at such sale, a bidder at the foreclosure sale of such Mortgage
Loan would have to bid an amount sufficient to pay off all sums due under the
Mortgage Loan and the Senior Liens or purchase the Mortgaged Property subject to
the Senior Liens. In the event that such proceeds from a foreclosure or similar
sale of the related Mortgaged Property are insufficient to satisfy all Senior
Liens and the Mortgage Loan in the aggregate, the Trust Fund, as the holder of
the junior lien, and, accordingly, holders of one or more Classes of the
Securities bear (i) the risk of delay in distributions while a deficiency
judgment against the borrower is obtained and (ii) the risk of loss if the
deficiency judgment is not realized upon. Moreover, deficiency judgments may not
be available in certain jurisdictions. In addition, a junior mortgagee may not
foreclose on the property securing a junior mortgage unless it forecloses
subject to the senior mortgages.
 
     Liquidation expenses with respect to defaulted junior mortgage loans do not
vary directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that the Master Servicer took the same steps in
realizing upon a defaulted junior mortgage loan having a small remaining
principal balance as it would in the case of a defaulted junior mortgage loan
having a large remaining principal balance, the amount realized after expenses
of liquidation would be smaller as a percentage of the outstanding principal
balance of the small junior mortgage loan than would be the case with the
defaulted junior mortgage loan having a large remaining principal balance.
Because the average outstanding principal balance of the Mortgage Loans is
smaller relative to the size of the average outstanding principal balance of the
loans in a typical pool of first priority mortgage loans, liquidation proceeds
may also be smaller as a percentage of the principal balance of a Mortgage Loan
than would be the case in a typical pool of first priority mortgage loans.
 
     If specified in the related Prospectus Supplement, a Trust Fund will
contain Additional Collateral Loans. Unless otherwise specified in the related
Prospectus Supplement, the security agreements and other similar security
instruments related to the Additional Collateral for the Loans in a Trust Fund
will, in the case of Additional Collateral consisting of personal property,
create first liens thereon, and, in the case of Additional Collateral consisting
of real estate, create first or junior liens thereon. Additional Collateral, or
the liens thereon in favor of the related Additional Collateral Loans, may be
greater or less in value than the principal balances of such Additional
Collateral Loans, the Appraised Values of the underlying Mortgaged Properties or
the differences, if any, between such principal balances and such Appraised
Values, and the requirements that Additional Collateral be maintained may be
terminated upon the reduction of the Loan-to-Value Ratios or principal balances
of the related Additional Collateral Loans to certain pre-determined amounts.
Additional Collateral (including any related third-party guarantees) may be
provided either in addition to or in lieu of primary mortgage insurance policies
for the Additional Collateral Loans in a Trust Fund, as specified in the related
Prospectus Supplement. Guarantees supporting Additional Collateral Loans may be
guarantees of payment or guarantees of collectability and may be full guarantees
or limited guarantees. If a Trust Fund includes Additional Collateral Loans, the
related Prospectus Supplement will specify the nature and extent of such
Additional Collateral Loans and of the related Additional Collateral. If
specified in such Prospectus Supplement, the Trustee, on behalf of the related
Securityholders, will have only the right to receive certain
 
                                       23
 

<PAGE>

<PAGE>
proceeds from the disposition of any such Additional Collateral consisting of
personal property and the liens thereon will not be assigned to the Trustee. No
assurance can be given as to the amount of proceeds, if any, that might be
realized from the disposition of the Additional Collateral for any of the
Additional Collateral Loans. See 'Certain Legal Aspects of
Loans -- Anti-Deficiency Legislation and Other Limitations on Lenders' herein.
 
     Additional Collateral Loans may include Nest Egg Mortgage LoansSM. Such
Mortgage Loans are interest-only Mortgage Loans for an initial period specified
in the related Prospectus Supplement. If the related Mortgagor pledges an
eligible life insurance policy as Additional Collateral after such initial
period, the Mortgagor will continue to make interest-only payments with respect
to the Mortgage Loan until the final scheduled payment on such Mortgage Loan, as
described in the Prospectus Supplement.
 
     The percentage of Mortgage Loans which are owner-occupied will be disclosed
in the related Prospectus Supplement. Unless otherwise specified in the
Prospectus Supplement, the sole basis for a representation that a given
percentage of the Mortgage Loans are secured by Single Family Property that is
owner-occupied will be either (i) the making of a representation by the
Mortgagor at origination of the Mortgage Loan either that the underlying
Mortgaged Property will be used by the borrower for a period of at least six
months every year or that the borrower intends to use the Mortgaged Property as
a primary residence, or (ii) a finding that the address of the underlying
Mortgaged Property is the borrower's mailing address as reflected in the
Servicer's records. To the extent specified in the related Prospectus
Supplement, the Mortgaged Properties may include non-owner occupied investment
properties and vacation and second homes. Mortgage Loans secured by investment
properties and Multifamily Property may also be secured by an assignment of
leases and rents and operating or other cash flow guarantees relating to the
Loans to the extent specified in the related Prospectus Supplement.
 
     The characteristics of the Mortgage Loans comprising or underlying the
Mortgage Assets for a Series may vary to the extent that credit support is
provided in levels satisfactory to the Rating Agency which assigns a rating to a
Series of Securities. Unless otherwise specified in the related Prospectus
Supplement for a Series, the following selection criteria shall apply with
respect to the Mortgage Loans comprising the Mortgage Assets:
 
          (a)  no Mortgage Loan will have had a Loan-to-Value Ratio at
     origination in excess of 95%;
 
          (b)  no Mortgage Loan that is a Conventional Loan secured by a Single
     Family Property may have a Loan-to-Value Ratio in excess of 80%, unless
     covered by a primary mortgage insurance policy as described herein;
 
          (c)  each Mortgage Loan must have an original term to maturity of not
     less than 10 years and not more than 40 years;
 
          (d)  no Mortgage Loan may be included which, as of the Cut-off Date,
     is more than 30 days delinquent as to payment of principal or interest; and
 
          (e)  no Mortgage Loan (other than a Cooperative Loan) may be included
     unless a title insurance policy and a standard hazard insurance policy
     (which may be a blanket policy) is in effect with respect to the Mortgaged
     Property securing such Mortgage Loan.
 
     Each Mortgage Loan will be selected by the Depositor for inclusion in a
Trust Fund from among those purchased by the Depositor, either directly or
through its affiliates, from a Seller or Sellers. The related Prospectus
Supplement will specify the extent of Mortgage Loans so acquired. Other mortgage
loans available for purchase by the Depositor may have characteristics which
would make them eligible for inclusion in a Trust Fund but were not selected for
inclusion in such Trust Fund.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Mortgage Loans to be included in a Trust Fund will be delivered either directly
or indirectly to the Depositor by one or more Sellers identified in the related
Prospectus Supplement, concurrently with the issuance of the related Series of
Securities (a 'Designated Seller Transaction'). Such Securities may be sold in
whole or in part to any such Seller in exchange for the related Mortgage Loans,
or may be offered under any of the other methods described herein under 'Methods
of Distribution.' The related Prospectus Supplement for a Trust Fund composed of
Mortgage Loans acquired by the Depositor pursuant to a Designated Seller
Transaction will generally include information, provided by the related Seller,
about the Seller, the Mortgage Loans and the underwriting standards applicable
to the Mortgage Loans. Neither the Depositor nor any of its affiliates (other
than the Seller, if applicable) will make any representation or warranty with
respect to such Mortgage Loans, or any representation as to the accuracy or
completeness of such information provided by the Seller and no assurances are
made as to any such Seller's
 
                                       24

financial strength, stability or wherewithal to honor its repurchase obligations
for breaches of representations and warranties or otherwise honor its
obligations.
 
     The Depositor will not require that a standard hazard or flood insurance
policy be maintained for any Cooperative Loan. Generally, the cooperative itself
is responsible for maintenance of hazard insurance for the property owned by the
cooperative and the tenant-stockholders of that cooperative do not maintain
individual hazard insurance policies. To the extent, however, a cooperative and
the related borrower on a Cooperative Note do not maintain such insurance or do
not maintain adequate coverage or any insurance proceeds are not applied to the
restoration of the damaged property, damage to such borrower's Cooperative
Dwelling or such cooperative's building could significantly reduce the value of
the collateral securing such Cooperative Note.
 
     The initial Loan-to-Value Ratio of any Mortgage Loan represents the ratio
of the principal amount of the Mortgage Loan at origination, plus in the case of
a Mortgage Loan secured by a junior lien, the principal amount of the related
Senior Lien, to the Appraised Value of such Mortgaged Property.
 
     Unless otherwise specified in the related Prospectus Supplement, with
respect to Buy-Down Loans, during the period (the 'Buy-Down Period') when the
borrower is not obligated to pay the full Scheduled Payment otherwise due on
such loan, each of the Buy-Down Loans will provide for Scheduled Payments based
on a hypothetical reduced interest rate (the 'Buy-Down Mortgage Rate') that will
not have been more than 3% below the mortgage rate at origination, and for
annual increases in the Buy-Down Mortgage Rate during the Buy-Down Period that
will not exceed 1%. The Buy-Down Period will not exceed three years. Unless
specified otherwise in the related Prospectus Supplement, the maximum amount of
funds ('Buy-Down Amounts') that may be contributed by the Servicer of the
related Buy-Down Loan is limited to 6% of the Appraised Value of the related
Mortgaged Property. This limitation does not apply to contributions from
immediate relatives or the employer of the mortgagor. Except as may be otherwise
indicated in the related Prospectus Supplement, the borrower under each Buy-Down
Loan will have been qualified at a mortgage rate which is not more than 3% per
annum below the current mortgage rate at origination. Accordingly, the repayment
of a Buy-Down Loan is dependent on the ability of the borrower to make larger
Scheduled Payments after the Buy-Down Amounts have been depleted and, for
certain Buy-Down Loans, while such Buy-Down Amounts are being depleted.
 
     Unless otherwise specified in the related Prospectus Supplement, with
respect to Multifamily Loans, (a) no Mortgage Loan will have been delinquent for
more than 30 days within the 12-month period ending with the Cut-off Date, (b)
no more than two payments will have been 30 days or more delinquent during a
three-year period ending on the Cut-off Date, (c) Mortgage Loans with respect to
any single borrower will not exceed 5% of the aggregate principal balance of the
Loans comprising the Mortgage Assets as of the Cut-off Date, and (d) the debt
service coverage ratio with respect to each Mortgage Loan (calculated as
described in the related Prospectus Supplement) will not be less than 11:1.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Bi-Weekly Loans will consist of fixed-rate, bi-weekly payment, conventional,
fully-amortizing Mortgage Loans payable on every other Friday during the term
thereof and secured by first mortgages on one- to four-family residential
properties.
 
     Unless otherwise specified in the related Prospectus Supplement, ARMs will
provide for a fixed initial mortgage rate for either the first six or twelve
Scheduled Payments. Thereafter, the Mortgage Rates are subject to periodic
adjustment based, subject to the applicable limitations, on changes in the
relevant Index described in the applicable Prospectus Supplement, to a rate
equal to the Index plus the Gross Margin, which is a fixed percentage spread
over the Index established contractually for each ARM, at the time of its
origination. An ARM may be convertible into a fixed-rate Mortgage Loan. To the
extent specified in the related Prospectus Supplement, any ARM so converted may
be subject to repurchase by the Seller, the Servicer or the Master Servicer.
 
     ARMs have features that can cause payment increases that some borrowers may
find difficult to make. However, each of the ARMs provides that its mortgage
rate may not be adjusted to a rate above the applicable lifetime mortgage rate
cap (the 'Maximum Mortgage Rate') or below the applicable lifetime minimum
mortgage rate (the 'Minimum Mortgage Rate'), if any, for such ARM. In addition,
certain of the ARMs provide for limitations on the maximum amount by which their
mortgage rates may adjust for any single adjustment period (the 'Periodic Rate
Cap'). Some ARMs are payable in self-amortizing payments of principal and
interest. Other ARMs ('Negatively Amortizing ARMs') instead provide for
limitations on changes in the Scheduled Payment on such ARMs to protect
borrowers from payment increases due to rising interest rates.
 
                                       25
 

<PAGE>

<PAGE>
Such limitations can result in Scheduled Payments which are greater or less than
the amount necessary to amortize a Negatively Amortizing ARM by its original
maturity at the mortgage rate in effect during any particular adjustment period.
In the event that the Scheduled Payment is not sufficient to pay the interest
accruing on a Negatively Amortizing ARM, then the Deferred Interest is added to
the principal balance of such ARM causing the negative amortization thereof, and
will be repaid through future Scheduled Payments. If specified in the related
Prospectus Supplement, Negatively Amortizing ARMs may provide for the extension
of their original stated maturity to accommodate changes in their mortgage rate.
The relevant Prospectus Supplement will specify whether the ARMs comprising or
underlying the Mortgage Assets are Negatively Amortizing ARMs.
 
     If applicable, the Prospectus Supplement for each Series will specify the
Index to be used with respect to any Mortgage Loans underlying such Series.
 
     The related Prospectus Supplement for each Series will provide information
with respect to the Mortgage Loans as of the Cut-off Date, generally including,
among other things, (a) the aggregate outstanding principal balance of the
Mortgage Loans; (b) the weighted average mortgage rate on the Mortgage Loans,
and, in the case of ARMs, the weighted average of the current mortgage rates and
the Maximum Mortgage Rates, if any; (c) the average outstanding principal
balance of the Mortgage Loans; (d) the weighted average remaining term-to-stated
maturity of the Mortgage Loans and the range of remaining terms-to-stated
maturity; (e) the range of Loan-to-Value Ratios of the Mortgage Loans; (f) the
relative percentage (by outstanding principal balance as of the Cut-off Date) of
Mortgage Loans that are Additional Collateral Loans, ARMs, Balloon Loans,
Buy-Down Loans, GEM Loans, GPM Loans, Cooperative Loans, Conventional Loans,
Bi-Weekly Loans, FHA Loans and VA Loans, (g) the percentage of Mortgage Loans
(by outstanding principal balance as of the Cut-off Date) that are covered by
primary mortgage insurance policies; (h) any pool insurance policy, special
hazard insurance policy or bankruptcy bond or other credit support relating to
the Mortgage Loans; (i) the geographic distribution of the Mortgaged Properties
securing the Mortgage Loans, (j) the percentage of Mortgage Loans (by principal
balance as of the Cut-off Date) that are secured by Single Family Property,
Multifamily Property, Cooperative Dwellings, investment property and vacation or
second homes and (k) with respect to Mortgage Loans secured by a junior lien,
the amount of the related Senior Liens. The related Prospectus Supplement will
also specify any other limitations on the types or characteristics of Mortgage
Loans which may comprise or underlie the Mortgage Assets for a Series.
 
     If information of the nature described above respecting the Mortgage Loans
is not known to the Depositor at the time the Securities are initially offered,
more general information of the nature described above will be provided in the
Prospectus Supplement and the final specific information will be set forth in a
Current Report on Form 8-K to be available to investors on the date of issuance
of the related Series and to be filed, together with the related Pooling and
Servicing Agreement, with respect to each Series of Certificates, or the related
Servicing Agreement, Owner Trust Agreement and Indenture, with respect to each
Series of Notes, with the Commission within 15 days after the initial issuance
of such Securities.
 
THE MANUFACTURED HOME LOANS
 
     The Manufactured Home Loans comprising or underlying the Mortgage Assets
for a Series of Securities will consist of manufactured housing conditional
sales contracts and installment loan agreements originated by a manufactured
housing dealer in the ordinary course of business and purchased by the
Depositor. Each Manufactured Home Loan will have been originated by a bank or
savings institution which is a FNMA- or FHLMC-approved seller/servicer or by any
financial institution approved for insurance by the Secretary of Housing and
Urban Development pursuant to Section 2 of the National Housing Act.
 
     The Manufactured Home Loans may be Conventional Loans, FHA Loans or VA
Loans. Each Manufactured Home Loan will be secured by a Manufactured Home.
Unless otherwise specified in the related Prospectus Supplement, the
Manufactured Home Loans will be fully amortizing and will bear interest at a
fixed interest rate.
 
     Unless otherwise specified in the related Prospectus Supplement for a
Series, the Manufactured Homes securing the Manufactured Home Loans consist of
manufactured homes within the meaning of 42 United States Code, Section 5402(6).
In addition, unless otherwise specified in the related Prospectus Supplement for
a Series,
 
                                       26
 

<PAGE>

<PAGE>
the following restrictions apply with respect to Manufactured Home Loans
comprising or underlying the Mortgage Assets for a Series:
 
          (a) no Manufactured Home Loan will have had a Loan-to-Value Ratio at
     origination in excess of 95%;
 
          (b) each Manufactured Home Loan must have an original term to maturity
     of not less than three years and not more than 25 years;
 
          (c) no Manufactured Home Loan may be more than 30 days delinquent as
     to payment of principal or interest as of the Cut-off Date; and
 
          (d) each Manufactured Home Loan must have, as of the Cut-off Date, a
     standard hazard insurance policy (which may be a blanket policy) in effect
     with respect thereto.
 
     The initial Loan-to-Value Ratio of any Manufactured Home Loan represents
the ratio of the principal amount of the Manufactured Home Loan at origination
to the Appraised Value of such Manufactured Home. With respect to underwriting
of Manufactured Home Loans, see 'Loan Underwriting Procedures and Standards.'
With respect to servicing of Manufactured Home Loans, see 'Servicing of Loans.'
 
     The related Prospectus Supplement for each Series will provide information
with respect to the Manufactured Home Loans comprising the Mortgage Assets as of
the Cut-off Date, including, among other things, (a) the aggregate outstanding
principal balance of the Manufactured Home Loans comprising or underlying the
Mortgage Assets; (b) the weighted average interest rate on the Manufactured Home
Loans; (c) the average outstanding principal balance of the Manufactured Home
Loans; (d) the weighted average remaining scheduled term to maturity of the
Manufactured Home Loans and the range of remaining scheduled terms to maturity;
(e) the range of Loan-to-Value Ratios of the Manufactured Home Loans; (f) the
relative percentages (by principal balance as of the Cut-off Date) of
Manufactured Home Loans that were made on new Manufactured Homes and on used
Manufactured Homes; (g) any pool insurance policy, special hazard insurance
policy or bankruptcy bond or other credit support relating to the Manufactured
Home Loans; and (h) the distribution by state of Manufactured Homes securing the
Loans. The related Prospectus Supplement will also specify any other limitations
on the types or characteristics of Manufactured Home Loans which may be included
in the Mortgage Assets for a Series.
 
     If information of the nature specified above respecting the Manufactured
Home Loans is not known to the Depositor at the time the Securities are
initially offered, more general information of the nature described above will
be provided in the Prospectus Supplement and the final specific information will
be set forth in a Current Report on Form 8-K to be available to investors on the
date of issuance of the related Series and to be filed with the Commission
within 15 days after the initial issuance of such Securities.
 
COLLECTION ACCOUNT AND CERTIFICATE ACCOUNT
 
     Unless otherwise specified in the related Prospectus Supplement, a separate
Collection Account for each Series will be established by the Master Servicer in
the name of the Trustee for deposit of all distributions received with respect
to the Mortgage Assets for such Series, all Advances (other than Advances
deposited into the Certificate Account), the amount of cash to be initially
deposited therein, if any, reinvestment income thereon and certain other amounts
required to be deposited therein pursuant to the related Pooling and Servicing
Agreement or the related Servicing Agreement and Indenture. Unless otherwise
specified in the related Prospectus Supplement or related Agreement, any
reinvestment income or other gain from investments of funds in the Collection
Account will be credited to such Collection Account, and any loss resulting from
such investments will be charged to such Collection Account. Such reinvestment
income may, however, be payable to the Master Servicer or to a Servicer as
additional servicing compensation. See 'Servicing of Loans' and 'The
Agreements -- Investment of Funds.' In such a case, such reinvestment income
would not be included in calculation of the Available Distribution Amount. See
'Description of the Securities -- Distributions on the Securities.'
 
     Funds on deposit in the Collection Account will be available for deposit
into the Certificate Account for certain payments provided for in the related
Pooling and Servicing Agreement or the related Servicing Agreement and
Indenture. Unless otherwise specified in the Prospectus Supplement or the
related Agreement, amounts in the Collection Account constituting reinvestment
income which is payable to the Master Servicer as additional servicing
compensation or for the reimbursement of advances or expenses, amounts in
respect of any
 
                                       27
 

<PAGE>

<PAGE>
Servicing Fee, Retained Interest, and amounts to be deposited into any reserve
fund will not be included in determining amounts to be remitted to the Trustee
for deposit into the Certificate Account.
 
     A separate Certificate Account will be established by the Trustee or, if so
specified in the related Prospectus Supplement, by the Master Servicer, in
either case in the name of the Trustee for the benefit of the Securityholders
into which all funds received from the Master Servicer and all required
withdrawals from any reserve funds and any draws on any Financial Guarantee
Insurance for such Series will be deposited, pending distribution to the
Securityholders. Unless otherwise specified in the related Prospectus
Supplement, any reinvestment income or other gain from investments of funds in
the Certificate Account will be credited to the Certificate Account and any loss
resulting from such investments will be charged to such Certificate Account.
Such reinvestment income, may, however, be payable to the Master Servicer or the
Trustee as additional servicing compensation. On each Distribution Date, all
funds on deposit in the Certificate Account, subject to certain permitted
withdrawals by the Trustee as set forth in the related Agreement, will be
available for remittance to the Securityholders; provided that, if it is
specified in the related Prospectus Supplement that the Certificate Account will
be maintained by the Master Servicer in the name of the Trustee, then, prior to
each Distribution Date, funds in the Certificate Account will be transferred to
a separate account established by and in the name of the Trustee from which the
funds on deposit therein will, subject to permitted withdrawals by the Trustee
as specified above, be available for remittance to the Securityholders. See also
'The Agreements -- Certificate Account' herein.
 
OTHER FUNDS OR ACCOUNTS
 
     A Trust Fund may include certain other funds and accounts or a security
interest in certain funds and accounts for the purpose of, among other things,
paying certain administrative fees and expenses of the Trust Fund and
accumulating funds pending their distribution. If so specified in the related
Prospectus Supplement, certain funds may be established with the Trustee with
respect to Buy-Down Loans, GPM Loans, or other Loans having special payment
features included in the Trust Fund in addition to or in lieu of any such
similar funds to be held by the Servicer. See 'Servicing of Loans -- Payments on
Loans; Deposits to Collection Accounts.' If Private Mortgage-Backed Securities
are backed by GPM Loans and the value of a Multiple Class Series is determined
on the basis of the scheduled maximum principal balance of the GPM Loans, a GPM
Fund will be established which will be similar to that which would be
established if GPM Loans constituted the Mortgage Assets. See 'Servicing of
Loans -- Payments on Loans; Deposits to Collection Accounts' herein. Other
similar accounts may be established as specified in the related Prospectus
Supplement.
 
                   LOAN UNDERWRITING PROCEDURES AND STANDARDS
 
UNDERWRITING STANDARDS
 
     The Depositor expects that all Loans comprising the Mortgage Assets for a
Series will have been originated in accordance with the underwriting procedures
and standards described herein, except as otherwise set forth in the related
Prospectus Supplement.
 
     The Seller of the Loans (or other entity specified in the related
Prospectus Supplement, which may be the originator) will make representations
and warranties concerning compliance with such underwriting procedures and
standards. Additionally, unless otherwise specified in the related Prospectus
Supplement, all or a sample of the Loans comprising Mortgage Assets for a Series
will be reviewed by or on behalf of the Depositor to determine compliance with
such underwriting standards and procedures and compliance with other
requirements for inclusion in the Trust Fund.
 
     Mortgage Loans will have been originated by a savings and loan association,
savings bank, commercial bank, credit union, insurance company or similar
institution which is supervised and examined by a federal or state authority or
by a mortgagee approved by the Secretary of Housing and Urban Development
pursuant to Sections 203 and 211 of the National Housing Act or a wholly-owned
subsidiary thereof. Manufactured Home Loans may have been originated by such
institutions or by a financial institution approved for insurance by the
Secretary of Housing and Urban Development pursuant to Section 2 of the National
Housing Act. Except as otherwise set forth in the related Prospectus Supplement
for a Series of Securities, the originator of a Loan will have applied
underwriting procedures intended to evaluate the borrower's credit standing and
repayment ability
 
                                       28
 

<PAGE>

<PAGE>
and the value and adequacy of the related property as collateral. FHA Loans and
VA Loans will have been originated in compliance with the underwriting policies
of FHA and VA, respectively.
 
     Each borrower will have been required to complete an application designed
to provide to the original lender pertinent credit information about the
borrower. As part of the description of the borrower's financial condition, the
borrower will have furnished information with respect to its assets,
liabilities, income, credit history, employment history and personal
information, and an authorization to apply for a credit report which summarizes
the borrower's credit history with local merchants and lenders and any record of
bankruptcy. If the borrower was self-employed, the borrower will have been
required to submit copies of recent tax returns. The borrower may also have been
required to authorize verifications of deposits at financial institutions where
the borrower had demand or savings accounts. Certain considerations may cause an
originator of Loans to depart from these guidelines. For example, when two
individuals co-sign the loan documents, the incomes and expenses of both
individuals may be included in the computation. In the case of a Multifamily
Loan, the Mortgagor will also be required to provide certain information
regarding the related Multifamily Property, including a current rent roll and
operating income statements (which may be pro forma and unaudited). In addition,
the originator will generally also consider the location of the Multifamily
Property, the availability of competitive lease space and rental income of
comparable properties in the relevant market area, the overall economy and
demographic features of the geographic area and the Mortgagor's prior experience
in owning and operating properties similar to the Multifamily Properties.
 
     The adequacy of the property financed by the related Loan as security for
repayment of such Loan will generally have been determined by appraisal in
accordance with pre-established appraisal procedure guidelines for appraisals
established by or acceptable to the originator. Appraisers may be staff
appraisers employed by the Loan originator or independent appraisers selected in
accordance with pre-established guidelines established by the Loan originator.
The appraisal procedure guidelines will have required that the appraiser or an
agent on its behalf to personally inspect the property and to verify that it was
in good condition and that construction, if new, had been completed. The
appraisal will have been based upon a market data analysis of recent sales of
comparable properties and, when deemed applicable, a replacement cost analysis
based on the current cost of constructing or purchasing a similar property. With
respect to Multifamily Properties, the appraisal must specify whether an income
analysis, a market analysis or a cost analysis was used. An appraisal employing
the income approach to value analyzes a property's projected net cash flow,
capitalization and other operational information in determining the property's
value. The market approach to value analyzes the prices paid for the purchase of
similar properties in the property's area, with adjustments made for variations
between those other properties and the property being appraised. The cost
approach to value requires the appraiser to make an estimate of land value and
then determine the current cost of reproducing the improvements less any accrued
depreciation. In any case, the value of the property being financed, as
indicated by the appraisal, must be such that it currently supports, and is
anticipated to support in the future, the outstanding loan balance. Unless
otherwise specified in the related Prospectus Supplement, all appraisals are
required to conform to the Uniform Standards of Professional Appraisal Practice
and the Financial Institutions Reform, Recovery and Enforcement Act of 1989
('FIRREA') and must be on forms acceptable to the FNMA and/or FHLMC.
 
     Based on the data provided, certain verifications and the appraisal, a
determination will have been made by the original lender that the borrower's
monthly income would be sufficient to enable the borrower to meet its monthly
obligations on the Loan and other expenses related to the property (such as
property taxes, utility costs, standard hazard and primary mortgage insurance
and, if applicable, maintenance fees and other levies assessed by a Cooperative)
and certain other fixed obligations other than housing expenses. The originating
lender's guidelines for Loans secured by Single Family Property generally will
specify that Scheduled Payments plus taxes and insurance and all Scheduled
Payments extending beyond one year (including those mentioned above and other
fixed obligations, such as car payments) would equal no more than specified
percentages of the prospective borrower's gross income. These guidelines will
generally be applied only to the payments to be made during the first year of
the Loan. Except as otherwise specified in the related Prospectus Supplement,
with respect to Mortgage Loans that are Conventional Loans, underwriting
guidelines used to establish the relevant percentages of gross income will be
similar to underwriting guidelines used by FNMA and FHLMC at the time of
origination of the Loan, except that the ratio of Scheduled Payments and certain
other fixed obligations to monthly gross income may exceed the comparable FNMA
or FHLMC limits as specified in the related Prospectus Supplement.
 
                                       29
 

<PAGE>

<PAGE>
     With respect to FHA Loans and VA Loans, traditional underwriting guidelines
used by the FHA and the VA, as the case may be, which were in effect at the time
of origination of each Loan will generally have been applied. With respect to
Manufactured Home Loans that are Conventional Loans, the related Prospectus
Supplement will specify the required minimum down payment, the maximum amount of
purchase price eligible for financing, the maximum original principal amount
that may be financed, and the limitations on ratios of borrower's Scheduled
Payment to gross monthly income and monthly income net of other fixed payment
obligations.
 
     In the case of the Multifamily Loans, lenders typically look to the Debt
Service Coverage Ratio of a loan as an important measure of the risk of default
on such a loan. Unless otherwise defined in the related Prospectus Supplement,
the 'Debt Service Coverage Ratio' of a Multifamily Loan at any given time is the
ratio of (i) the Net Operating Income of the related Mortgaged Property for a
twelve-month period to (ii) the annualized scheduled payments on the Mortgage
Loan and on any other loan that is secured by a lien on the Mortgaged Property
prior to the lien of the related Mortgage. Unless otherwise defined in the
related Prospectus Supplement, 'Net Operating Income' means, for any given
period, the total operating revenues derived from a Multifamily Property during
such period, minus the total operating expenses incurred in respect of such
property during such period other than (i) non-cash items such as depreciation
and amortization, (ii) capital expenditures and (iii) debt service on loans
(including the related Mortgage Loan) secured by liens on such property. The Net
Operating Income of a Multifamily Property will fluctuate over time and may or
may not be sufficient to cover debt service on the related Mortgage Loan at any
given time. As the primary source of the operating revenues of a Multifamily
Property, rental income (and maintenance payments from tenant-stockholders of a
cooperatively owned Multifamily Property) may be affected by the condition of
the applicable real estate market and/or area economy. Increases in operating
expenses due to the general economic climate or economic conditions in a
locality or industry segment, such as increases in interest rates, real estate
tax rates, energy costs, labor costs and other operating expenses, and/or to
changes in governmental rules, regulations and fiscal policies, may also affect
the risk of default on a Multifamily Loan. Lenders also look to the
Loan-to-Value Ratio of a Multifamily Loan as a measure of risk of loss if a
property must be liquidated following a default.
 
     If so specified in the related Prospectus Supplement, the underwriting of a
Multifamily Loan may also include environmental testing. Under the laws of
certain states, contamination of real property may give rise to a lien on the
property to assure the costs of cleanup. In several states, such a lien has
priority over an existing mortgage lien on such property. In addition, under the
laws of some states and under the federal Comprehensive Environmental Response,
Compensation and Liability Act of 1980 ('CERCLA'), a lender may be liable, as an
'owner' or 'operator,' for costs of addressing releases or threatened releases
of hazardous substances at a property, if agents or employees of the lender have
become sufficiently involved in the operations of the borrower, regardless of
whether or not the environmental damage or threat was caused by the borrower or
a prior owner. A lender also risks such liability on foreclosure of the
mortgage. See 'Certain Legal Aspects of Mortgage Loans -- Environmental
Legislation.'
 
     With respect to Multifamily Property, the Loan originator will have made an
assessment of the capabilities of the management of the project, including a
review of management's past performance record, its management reporting and
control procedures (to determine its ability to recognize and respond to
problems) and its accounting procedures to determine cash management ability.
Income derived from the Mortgaged Property constituting investment property may
have been considered for underwriting purposes, rather than the income of the
borrower from other sources.
 
     With respect to Mortgaged Property consisting of vacation or second homes,
no income derived from the property will have been considered for underwriting
purposes.
 
     Certain types of Loans that may be included in the Mortgage Assets for a
Series are recently developed and may involve additional uncertainties not
present in traditional types of loans. For example, Balloon Loans, Buy-Down
Loans, GEM Loans and GPM Loans provide for escalating or variable payments by
the borrower. These types of Loans are underwritten on the basis of a judgment
that the borrower will have the ability to make larger Scheduled Payments in
subsequent years. ARMs may involve similar assessments.
 
     To the extent specified in the related Prospectus Supplement, the Depositor
may purchase Loans (or participation interests therein) for inclusion in a Trust
Fund that are underwritten under standards and procedures which vary from and
are less stringent than those described herein. For instance, Loans may be
underwritten under a 'limited documentation program,' if specified in the
Prospectus Supplement. With respect to such
 
                                       30
 

<PAGE>

<PAGE>
Loans, minimal investigation into the borrowers' credit history and income
profile is undertaken by the originator and such Loans may be underwritten
primarily on the basis of an appraisal of the Mortgaged Property and
Loan-to-Value Ratio on origination. Thus, if the Loan-to-Value Ratio is less
than a percentage specified in the related Prospectus Supplement, the originator
may forego certain aspects of the review relating to monthly income, and
traditional ratios of monthly or total expenses to gross income may not be
applied.
 
     In addition, Mortgage Loans may have been originated in connection with a
governmental program under which underwriting standards were significantly less
stringent and designed to promote home ownership or the availability of
affordable residential rental property notwithstanding higher risks of default
and losses. The related Prospectus Supplement will specify the underwriting
standards applicable to such Mortgage Loans.
 
     The underwriting standards applied by the Loan originator require that the
underwriting officers be satisfied that the value of the property being
financed, as indicated by an appraisal, currently supports and is anticipated to
support in the future the outstanding loan balance, and provides sufficient
value to mitigate the effects of adverse shifts in real estate values. Certain
states where the Mortgaged Properties may be located have 'antideficiency' laws
requiring, in general, that lenders providing credit on Single Family Property
look solely to the property for repayment in the event of foreclosure. See
'Certain Legal Aspects of Loans' herein.
 
     With respect to the underwriting standards applicable to any Mortgage
Loans, such underwriting standards generally include a set of specific criteria
pursuant to which the underwriting evaluation is made. However, the application
of such underwriting standards does not imply that each specific criterion was
satisfied individually. Rather, a Mortgage Loan will be considered to be
originated in accordance with a given set of underwriting standards if, based on
an overall qualitative evaluation, the loan is in substantial compliance with
such underwriting standards. For example, a Mortgage Loan may be considered to
comply with a set of underwriting standards, even if one or more specific
criteria included in such underwriting standards were not satisfied, if other
factors compensated for the criteria that were not satisfied or if the Mortgage
Loan is considered to be in substantial compliance with the underwriting
standards.
 
LOSS EXPERIENCE
 
     The general appreciation of real estate values experienced in the past has
been a factor in limiting the general loss experience on Conventional Loans.
However, there can be no assurance that the past pattern of appreciation in
value of the real property securing such Loans will continue. Further, there is
no assurance that appreciation of real estate values generally will limit loss
experiences on non-traditional housing such as Multifamily Property,
Manufactured Homes or Cooperative Dwellings. Similarly, no assurance can be
given that the value of the Mortgaged Property (including Cooperative Dwellings)
securing a Loan has remained or will remain at the level existing on the date of
origination of such Loan. If the residential real estate market should
experience an overall decline in property values such that the outstanding
balances of the Loans and any secondary financing on the Mortgaged Properties
securing such Loans become equal to or greater than the value of such Mortgaged
Properties, then the actual rates of delinquencies, foreclosures and losses
could be higher than those now generally experienced in the mortgage lending
industry. In addition, the value of property securing Cooperative Loans and the
delinquency rates with respect to Cooperative Loans, could be adversely affected
if the current favorable tax treatment of cooperative tenant stockholders were
to become less favorable. See 'Certain Legal Aspects of Loans' herein.
 
     No assurance can be given that values of Manufactured Homes have or will
remain at the levels existing on the dates of origination of the related Loan.
Manufactured Homes are less likely to experience appreciation in value and more
likely to experience depreciation in value over time than other types of
Mortgaged Property. Additionally, delinquency, loss and foreclosure experience
on Manufactured Home Loans may be adversely affected to a greater degree by
regional and local economic conditions than more traditional Mortgaged Property.
Loans secured by Multifamily Property may also be more susceptible to losses due
to changes in local and regional economic conditions than Loans secured by
Single Family Property. For example, unemployment resulting from an economic
downturn in local industry may sharply affect occupancy rates. Also, interest
rate fluctuations can make home ownership a more attractive alternative to
renting, causing occupancy rates and market rents to decline. New construction
can create an oversupply, particularly in a market that has experienced high
vacancy rates.

     To the extent that losses resulting from delinquencies, losses and
foreclosures or repossession of Mortgaged Property with respect to Loans
included in the Mortgage Assets for a Series of Securities are not covered by
the methods of credit support or the insurance policies described herein or in
the related Prospectus Supplement, such losses will be borne by Holders of the
Securities of such Series. Even where credit support covers all losses resulting
from delinquency and foreclosure or repossession, the effect of foreclosures and
repossessions may be to increase prepayment experience on the Mortgage Assets,
thus reducing average weighted life and affecting yield to maturity. See 'Yield,
Prepayment and Maturity Considerations.'
 
REPRESENTATIONS AND WARRANTIES
 
     Unless otherwise specified in the related Prospectus Supplement or in the
related Agreement, the Seller (or other party as described in the related
Prospectus Supplement) will represent and warrant to the Depositor and the
Trustee with respect to the Mortgage Loans comprising the Mortgage Assets in a
Trust Fund, upon delivery of the Mortgage Loans to the Trustee hereunder, among
other things, generally that: (i) any required hazard and primary mortgage
insurance policies were effective at the origination of such Mortgage Loan, and
each such policy remained in effect on the date of purchase of such Mortgage
Loan from the Seller by or on behalf of the Depositor; (ii) either (A) a title
insurance policy insuring (subject only to permissible title insurance
exceptions) the lien status of the Mortgage was effective at the origination of
such Mortgage Loan and such policy remained in effect on the date of purchase of
the Mortgage Loan from the Seller by or on behalf of the Depositor or (B) if the
Mortgaged Property securing such Mortgage Loan is located in an area where such
policies are generally not available, there is in the related mortgage file an
attorney's certificate of title indicating (subject to such permissible
exceptions set forth therein) the first lien status of the mortgage; (iii) the
Seller has good title to such Mortgage Loan and such Mortgage Loan was subject
to no offsets, defenses or counterclaims except as may be provided under the
Relief Act and except to the extent that any buydown agreement exists for a
Buy-Down Loan; (iv) there are no mechanics' liens or claims for work, labor or
material affecting the related Mortgaged Property which are, or may be a lien
prior to, or equal with, the lien of the related Mortgage (subject only to
permissible title insurance exceptions); (v) the related Mortgaged Property is
free from material damage and at least in adequate repair; (vi) there are no
delinquent tax or assessment liens against the related Mortgaged Property; (vii)
such Mortgage Loan is not more than 30 days' delinquent as to any scheduled
payment of principal and/or interest; (viii) if a primary mortgage insurance
policy is required with respect to such Mortgage Loan, such Mortgage Loan is the
subject of such a policy; and (ix) such Mortgage Loan was made in compliance
with, and is enforceable under, all applicable local, state and federal laws in
all material respects.
 
     If the Mortgage Loans include Cooperative Loans, no representations or
warranties with respect to title insurance or hazard insurance will be given. In
addition, if the Mortgage Loans include Condominium Loans, no representation
regarding hazard insurance will be given. Generally, the Cooperative or
Condominium Association itself is responsible for the maintenance of hazard
insurance for property owned by the Cooperative and the Condominium Association
is responsible for maintaining standard hazard insurance, insuring the entire
Condominium Building (including each individual Condominium Unit), and the
borrowers of that Cooperative or Condominium do not maintain separate hazard
insurance on their individual Cooperative Dwellings or Condominium Units. See
'Servicing of Loans -- Maintenance of Insurance Policies and Other Servicing
Procedures' herein. With respect to a Cooperative Loan, the Seller (or other
party as described in the related Prospectus Supplement) will represent and
warrant that (i) the security interest created by the cooperative security
agreements is a valid first lien on the collateral securing the Cooperative Loan
(subject to the right of the related Cooperative to cancel shares and terminate
the proprietary lease for unpaid assessments) and (ii) the related Cooperative
Dwelling is free of material damage and in good repair.
 
     Unless otherwise specified in the related Prospectus Supplement, with
respect to each Manufactured Home Loan, the Seller (or other party as described
in the related Prospectus Supplement) will represent and warrant, among other
things that (i) immediately prior to the transfer and assignment of the
Manufactured Home Loans to the Trustee, the Seller had good title to, and was
the sole owner of, each Manufactured Home Loan; (ii) as of the date of such
transfer and assignment, the Manufactured Home Loans are subject to no offsets,
defenses or counterclaims; (iii) each Manufactured Home Loan at the time it was
made complied in all material respects with applicable state and federal laws,
including usury, equal credit opportunity and truth-in-lending or similar
disclosure laws; (iv) as of the date of such transfer and assignment, each
Manufactured Home Loan constitutes a valid first lien on the related
Manufactured Home and such Manufactured Home is free of material damage and
 
                                       32
 

<PAGE>

<PAGE>
is in good repair; (v) as of the date of such representation and warranty, no
Manufactured Home Loan is more than 30 days delinquent and there are no
delinquent tax or assessment liens against the related Manufactured Home; and
(vi) with respect to each Manufactured Home Loan, any required hazard insurance
policy was effective at the origination of each Manufactured Home Loan and
remained in effect on the date of the transfer and assignment of the
Manufactured Home Loan from the Depositor and that all premiums due on such
insurance have been paid in full.
 
     Upon the discovery of the breach of any representation or warranty made by
the Master Servicer in respect of a Loan that materially and adversely affects
the interest of the Securityholder in such Loan, the Seller (or other party as
described in the Prospectus Supplement) will be obligated to cure such breach in
all material respects, repurchase such Loan from the Trustee, or deliver a
Qualified Substitute Mortgage Loan as described below under 'The
Agreements -- Assignment of Mortgage Assets.' See 'Risk Factors -- Limited
Obligations and Assets of the Depositor.' If the Seller or other party fails to
cure or repurchase, another party may be required to cure or repurchase as
described in the Prospectus Supplement. The PMBS Trustee (in the case of Private
Mortgage-Backed Securities) or the Trustee, as applicable, will be required to
enforce this obligation following the practices it would employ in its good
faith business judgment were it the owner of such Loan. If so specified in the
related Prospectus Supplement, the Master Servicer may be obligated to enforce
such obligations rather than the Trustee or PMBS Trustee.
 
                               SERVICING OF LOANS
 
GENERAL
 
     Customary servicing functions with respect to Loans constituting the
Mortgage Assets in the Trust Fund will be provided by the Master Servicer
directly or through one or more servicers (the 'Servicers') subject to
supervision by the Master Servicer. If the Master Servicer is not directly
servicing the Loans, then the Master Servicer will (i) administer and supervise
the performance by the Servicers of their servicing responsibilities under their
servicing agreements ('Sub-Servicing Agreements') with the Master Servicer, (ii)
maintain any standard or special hazard insurance policy, primary mortgage
insurance bankruptcy bond or pool insurance policy required for the related
Loans and (iii) advance funds as described below under 'Advances.' If the Master
Servicer services the Loans through Servicers as its agents, the Master Servicer
will be ultimately responsible for the performance of all servicing activities,
including those performed by the Servicers, notwithstanding its delegation of
certain responsibilities to such Servicer.
 
     The Master Servicer will be a party to the Pooling and Servicing Agreement
or Servicing Agreement for any Series for which Loans comprise the Mortgage
Assets and may be a party to a Participation Agreement executed with respect to
any Participation Securities which constitute the Mortgage Assets. The Master
Servicer may be an affiliate of the Depositor. Unless otherwise specified in the
related Prospectus Supplement, the Master Servicer and each Servicer will be
required to be a FNMA- or FHLMC-approved seller/servicer and, in the case of FHA
Loans, approved by HUD as an FHA mortgagee.
 
     The Master Servicer will be paid a Servicing Fee for the performance of its
services and duties under each Pooling and Servicing Agreement or Servicing
Agreement as specified in the related Prospectus Supplement. Each Servicer, if
any, will be entitled to receive a portion of the Servicing Fee. In addition,
the Master Servicer or Servicer may be entitled to retain late charges,
assumption fees and similar charges to the extent collected from mortgagors. If
a Servicer is terminated by the Master Servicer, the servicing function of the
Servicer will be either transferred to a substitute Servicer or performed by the
Master Servicer. The Master Servicer will be entitled to retain the portion of
the Servicing Fee paid to the Servicer under a terminated Sub-Servicing
Agreement if the Master Servicer elects to perform such servicing functions
itself.
 
     The Master Servicer, at its election, may pay itself the Servicing Fee for
a Series with respect to each Mortgage Loan either by (a) withholding the
Servicing Fee from any scheduled payment of interest prior to the deposit of
such payment in the Collection Account for such Series, (b) withdrawing the
Servicing Fee from the Collection Account after the entire Scheduled Payment has
been deposited in the Collection Account, or (c) requesting that the Trustee pay
the Servicing Fee out of amounts in the Certificate Account.

COLLECTION PROCEDURES; ESCROW ACCOUNTS
 
     The Master Servicer will make reasonable efforts to collect all payments
required to be made under the Mortgage Loans and will, consistent with the
related Pooling and Servicing Agreement or Servicing Agreement for a Series and
any applicable insurance policies and other forms of credit support, follow such
collection procedures as it follows with respect to comparable loans held in its
own portfolio. Consistent with the above, the Master Servicer may, in its
discretion, (i) waive any assumption fee, late payment charge, or other charge
in connection with a Loan and (ii) arrange with a mortgagor a schedule for the
liquidation of delinquencies by extending the Due Dates for Scheduled Payments
on such Loan, provided, however, that the Master Servicer shall first determine
that any such waiver or extension will not impair the coverage of any related
insurance policy or materially and adversely affect the lien of the related
Mortgage or the lien on any related Additional Collateral. In addition, unless
otherwise specified in the related Prospectus Supplement, if a material default
occurs or a payment default is reasonably foreseeable with respect to a
Multifamily Loan, the Master Servicer will be permitted, subject to any specific
limitations set forth in the related Pooling and Servicing Agreement or
Servicing Agreement and described in the related Prospectus Supplement, to
modify, waive or amend any term of such Mortgage Loan, including deferring
payments, extending the stated maturity date or otherwise adjusting the payment
schedule, provided that such modification, waiver or amendment (i) is reasonably
likely to produce a greater recovery with respect to such Mortgage Loan on a
present value basis than would liquidation and (ii) will not adversely affect
the coverage under any applicable instrument of credit enhancement.
 
     In the case of Multifamily Loans, a Mortgagor's failure to make required
Mortgage Loan payments may mean that operating income is insufficient to service
the mortgage debt, or may reflect the diversion of that income from the
servicing of the mortgage debt. In addition, a Mortgagor under a Multifamily
Loan that is unable to make Mortgage Loan payments may also be unable to make
timely payment of taxes and otherwise to maintain and insure the related
Mortgaged Property. In general, the related Master Servicer will be required to
monitor any Multifamily Loan that is in default, evaluate whether the causes of
the default can be corrected over a reasonable period without significant
impairment of the value of the related Mortgaged Property, initiate corrective
action in cooperation with the Mortgagor if cure is likely, inspect the related
Mortgaged Property and take such other actions as are consistent with the
servicing standard. A significant period of time may elapse before the Master
Servicer is able to assess the success of any such corrective action or the need
for additional initiatives. The time within which the Master Servicer can make
the initial determination of appropriate action, evaluate the success of
corrective action, develop additional initiatives, institute foreclosure
proceedings and actually foreclose (or accept a deed to a Mortgaged Property in
lieu of foreclosure) on behalf of the Securityholders of the related Series may
vary considerably depending on the particular Multifamily Loan, the Mortgaged
Property, the Mortgagor, the presence of an acceptable party to assume the
Multifamily Loan and the laws of the jurisdiction in which the Mortgaged
Property is located. If a Mortgagor files a bankruptcy petition, the Master
Servicer may not be permitted to accelerate the maturity of the related
Multifamily Loan or to foreclose on the Mortgaged Property for a considerable
period of time. See 'Certain Legal Aspects of Mortgage Loans.'
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer, to the extent permitted by law, will establish and maintain escrow
accounts ('Escrow Accounts') in which payments by borrowers to pay taxes,
assessments, mortgage and hazard insurance premiums, and other comparable items
that are required to be paid to the mortgagee will be deposited. Mortgage Loans
and Manufactured Home Loans may not require such payments under the loan related
documents, in which case the Master Servicer would not be required to establish
any Escrow Account with respect to such Loans. Withdrawals from the Escrow
Accounts are to be made to effect timely payment of taxes, assessments, mortgage
and hazard insurance, to refund to borrowers amounts determined to be overages,
to pay interest to borrowers on balances in the Escrow Account to the extent
required by law, to repair or otherwise protect the property securing the
related Loan and to clear and terminate such Escrow Account. The Master Servicer
will be responsible for the administration of the Escrow Accounts and generally
will make advances to such account when a deficiency exists therein.
 
DEPOSITS TO AND WITHDRAWALS FROM THE COLLECTION ACCOUNT
 
     Unless otherwise indicated in the related Prospectus Supplement, the
Collection Account will be an Eligible Account and the funds held therein may be
invested, pending remittance to the Trustee, in Eligible Investments. Unless
otherwise specified in the related Prospectus Supplement, the Master Servicer
will be
 
                                       34
 

<PAGE>

<PAGE>
entitled to receive as additional compensation any interest or other income
earned on funds in the Collection Account.
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer will deposit into the Collection Account for each Series on the
Business Day following the Closing Date any amounts representing Scheduled
Payments due after the related Cut-off Date but received by the Master Servicer
on or before the related Cut-off Date, and thereafter, after the date of receipt
thereof, the following payments and collections received or made by it (other
than in respect of principal of and interest on the related Loans due on or
before such Cut-off Date):
 
          (i) All payments on account of principal, including prepayments, on
     such Loans;
 
          (ii) All payments on account of interest on such Loans net of any
     portion thereof retained by the related Servicer (including the Master
     Servicer), if any, as servicing compensation on the Loans in accordance
     with the related Pooling and Servicing Agreement or Servicing Agreement;
 
          (iii) All Insurance Proceeds and all amounts received by the Master
     Servicer in connection with the liquidation of defaulted Loans or property
     acquired in respect thereof, whether through foreclosure sale or otherwise,
     including payments in connection with such Loans received from the
     mortgagor, other than amounts required to be paid to the mortgagor pursuant
     to the terms of the applicable Mortgage or otherwise pursuant to law
     ('Liquidation Proceeds'), exclusive of proceeds to be applied to the
     restoration or repair of the Mortgaged Property or released to the
     Mortgagor in accordance with the Master Servicer's normal servicing
     procedures, net of expenses incurred by the Master Servicer (or the related
     Servicer) in connection with the liquidation of any defaulted Mortgage Loan
     and not recovered under a primary mortgage insurance policy ('Liquidation
     Expenses');
 
          (iv) Any Buydown Funds (and, if applicable, investment earnings
     thereon) required to be paid as described herein;
 
          (v) All proceeds of any Mortgage Loan in such Trust Fund purchased
     (or, in the case of a substitution, certain amounts representing a
     principal adjustment) by the Master Servicer, the Seller or any other
     person pursuant to the terms of the related Pooling and Servicing Agreement
     or Servicing Agreement;
 
          (vi) All amounts required to be deposited therein in connection with
     any losses on Eligible Investments pursuant to the related Pooling and
     Servicing Agreement or Servicing Agreement; and
 
          (vii) All other amounts required to be deposited therein pursuant to
     the related Pooling and Servicing Agreement or Servicing Agreement.
 
     The Master Servicer is permitted, from time to time, to make withdrawals
from the Collection Account for certain purposes, as specifically set forth in
the related Pooling and Servicing Agreement or Servicing Agreement, which
generally will include the following, except as otherwise provided therein:
 
          (i) to make deposits to the Certificate Account in the amounts and in
     the manner provided in the Pooling and Servicing Agreement or Servicing
     Agreement;
 
          (ii) to reimburse itself for Advances, including amounts advanced in
     respect of taxes, insurance premiums or similar expenses as to any
     Mortgaged Property, out of late payments or collections on the related
     Mortgage Loan with respect to which such Advances were made;
 
          (iii) to pay to itself unpaid Servicing Fees, out of payments or
     collections of interest on each Mortgage Loan;
 
          (iv) to pay to itself as additional servicing compensation any
     investment income on funds deposited in the Collection Account, and, if so
     provided in the related Pooling and Servicing Agreement or Servicing
     Agreement, any profits realized upon disposition of a Mortgaged Property
     acquired by deed in lieu of foreclosure or otherwise allowed under the
     related Pooling and Servicing Agreement or Servicing Agreement;
 
          (v) to pay to itself or the Seller all amounts received with respect
     to each Mortgage Loan purchased, repurchased or removed pursuant to the
     terms of the related Pooling and Servicing Agreement or Servicing Agreement
     and not required to be distributed as of the date on which the related
     purchase price is determined;
 
                                       35
 

<PAGE>

<PAGE>
          (vi) to reimburse itself for any Advance previously made which the
     Master Servicer has determined to not be ultimately recoverable from
     Liquidation Proceeds, Insurance Proceeds or otherwise, subject, in the case
     of a Series with Senior Securities and Subordinate Securities, to certain
     limitations set forth in the related Pooling and Servicing Agreement or
     Servicing Agreement as described in the related Prospectus Supplement;
 
          (vii) to pay for costs and expenses incurred by the Trust Fund for
     environmental site assessments performed with respect to Multifamily
     Properties that constitute security for defaulted Mortgage Loans, and for
     any containment, clean-up or remediation of hazardous wastes and materials
     present on such Mortgaged Properties, as described below under
     ' -- Presentation of Claims; Realization Upon Defaulted Loans';
 
          (viii) to reimburse itself, the Trustee or the Depositor for certain
     other expenses incurred for which it, the Trustee or the Depositor is
     entitled to reimbursement or against which it, the Trustee or the Depositor
     is indemnified pursuant to the related Pooling and Servicing Agreement or
     the related Servicing Agreement and Indenture;
 
          (ix) to make any other withdrawals permitted by the related Pooling
     and Servicing Agreement or Servicing Agreement and described in the related
     Prospectus Supplement; and
 
          (x) to clear the Collection Account of amounts relating to the
     corresponding Loans in connection with the termination of the Trust Fund
     pursuant to the Pooling and Servicing Agreement or Servicing Agreement.
 
SERVICING ACCOUNTS
 
     Unless otherwise specified in the related Prospectus Supplement, in those
cases where a Servicer is servicing a Mortgage Loan, the Servicer will establish
and maintain an account (a 'Servicing Account') that will be an Eligible Account
and which is otherwise acceptable to the Master Servicer. The Servicer is
required to deposit into the Servicing Account all proceeds of Mortgage Loans
received by the Servicer, less its servicing compensation and any reimbursed
expenses and advances, to the extent permitted by the Sub-Servicing Agreement.
On the date specified in the related Prospectus Supplement, the Servicer will
remit to the Master Servicer all funds held in the Servicing Account with
respect to each Mortgage Loan, after deducting from such remittance an amount
equal to the servicing compensation and unreimbursed expenses and advances to
which it is then entitled pursuant to the related Sub-Servicing Agreement, to
the extent not previously paid to or retained by it. In addition on each such
date the Servicer will be required to remit to the Master Servicer any amount
required to be advanced pursuant to the related Sub-Servicing Agreement, and the
Servicer will also be required to the Master Servicer, within one business day
of receipt, the proceeds of any principal Prepayments and all Insurance Proceeds
and Liquidation Proceeds.
 
BUY-DOWN LOANS, GPM LOANS AND OTHER SUBSIDIZED LOANS
 
     With respect to each Buy-Down Loan, if any, included in a Trust Fund the
Master Servicer will deposit all Buy-Down Amounts in a custodial account (which
may be interest-bearing) complying with the requirements set forth above for the
Collection Account (the 'Buy-Down Fund'). The amount of such deposit, together
with investment earnings thereon at the rate specified in the related Prospectus
Supplement, will provide sufficient funds to support the payments on such
Buy-Down Loan on a level debt service basis. The Master Servicer will not be
obligated to add to the Buy-Down Account should amounts therein and investment
earnings prove insufficient to maintain the scheduled level of payments on the
Buy-Down Loans, in which event distributions to the Securityholders may be
affected. Unless otherwise provided in the related Prospectus Supplement, a Buy-
Down Fund will not be included in or deemed to be a part of the Trust Fund.
 
     The terms of certain of the Loans may provide for the contribution of
subsidy funds by the seller of the related Mortgaged Property or by another
entity. With respect to each such Loan, the Master Servicer will deposit the
subsidy funds in a custodial account (which may be interest-bearing) complying
with the requirements set forth above for the Collection Account set forth above
(a 'Subsidy Fund'). Unless otherwise specified in the related Prospectus
Supplement, the terms of each such Loan will provide for the contribution of the
entire undiscounted amount of subsidy amounts necessary to maintain the
scheduled level of payments due during the early years of such Loan. Neither the
Master Servicer, any Servicer nor the Depositor will be
 
                                       36
 

<PAGE>

<PAGE>
obligated to add to such Subsidy Fund any of its own funds. Unless otherwise
provided in the related Prospectus Supplement, such Subsidy Fund will not be
included in or deemed to be a part of the Trust Fund.
 
     If the Depositor values any GPM Loans deposited into the Trust Fund for a
Multiple Class Series on the basis of such GPM Loan's scheduled maximum
principal balance, the Master Servicer will, if and to the extent provided in
the related Prospectus Supplement, deposit in a custodial account (which may be
interest-bearing) (the 'GPM Fund') complying with the requirements set forth
above for the Collection Account an amount which, together with reinvestment
income thereon at the rate set forth in the related Prospectus Supplement, will
be sufficient to cover the amount by which payments of principal and interest on
such GPM Loans assumed in calculating payments due on the Securities of such
Multiple Class Series exceed the scheduled payments on such GPM Loans. The
Trustee will withdraw amounts from the GPM Fund for a Series upon a prepayment
of such GPM Loan as necessary and apply such amounts to the payment of principal
and interest on the Securities of such Series. Neither the Depositor, the Master
Servicer nor any Servicer will be obligated to supplement the GPM Fund should
amounts therein and investment earnings thereon prove insufficient to maintain
the scheduled level of payments, in which event, distributions to the
Securityholders may be affected. Unless otherwise specified in the related
Prospectus Supplement, such GPM Fund will not be included in or deemed to be
part of the Trust Fund.
 
     With respect to any other type of Loan which provides for payments other
than on the basis of level payments, an account may be established as described
in the related Prospectus Supplement on terms similar to those relating to the
Buy-Down Fund, Subsidiary Fund or the GPM Fund.
 
ADVANCES AND LIMITATIONS THEREON
 
     General. The related Prospectus Supplement will describe the circumstances
under which the Master Servicer or Servicer will make Advances with respect to
delinquent payments on Loans. Unless otherwise specified in the related
Prospectus Supplement, neither the Master Servicer nor any Servicer will be
obligated to make Advances, and such obligation may be limited in amount, may be
limited to advances received from the Servicers, if any, or may not be activated
until a certain portion of a specified reserve fund is depleted. If the Master
Servicer is obligated to make Advances, a surety bond or other credit support
may be provided with respect to such obligation as described in the related
Prospectus Supplement. Advances are intended to provide liquidity and not to
guarantee or insure against losses. Accordingly, any funds advanced are
recoverable by the Servicer or the Master Servicer, as the case may be, out of
amounts received on particular Loans which represent late recoveries of
principal or interest, proceeds of insurance polices or Liquidation Proceeds
respecting which any such Advance was made. If an Advance is made and
subsequently determined to be nonrecoverable from late collections, proceeds of
insurance polices or Liquidation Proceeds from the related Loan, the Servicer or
Master Servicer will be entitled to reimbursement from other funds in the
Certificate Account, Collection Account or Servicing Account, as the case may
be, or from a specified reserve fund as applicable, to the extent specified in
the related Prospectus Supplement. With respect to any Multiple Class Series, so
long as the related Subordinate Securities remain outstanding and subject to
certain limitations as described in the related Prospectus Supplement, such
Advances by the Master Servicer may also be reimbursable out of amounts
otherwise distributable to holders of the Subordinate Securities, if any.
 
     Advances in Connection With Prepaid Loans. In addition when a borrower
makes a principal prepayment in full between Due Dates on the related Loan, the
borrower will generally be required to pay interest on the principal amount
prepaid only to the date of such prepayment. If and to the extent provided in
the related Prospectus Supplement, in order that one or more Classes of the
Securityholders of a Series will not be adversely affected by any resulting
shortfall in interest, the Master Servicer may be obligated to advance moneys
from its own funds to the extent necessary to include in its remittance to the
Trustee for deposit into the Certificate Account an amount equal to a full
Scheduled Payment of interest on the related Loan (less any related Servicing
Fees). Any such principal prepayment, together with a full Scheduled Payment of
interest thereon (to the extent of such adjustment or advance), will be
distributed to Securityholders on the related Distribution Date. If the amount
necessary to include a full Scheduled Payment of interest as described above
exceeds the amount which the Master Servicer is obligated to advance, as
applicable, a shortfall may occur as a result of a prepayment in full. See
'Yield, Prepayment and Maturity Considerations.'

MAINTENANCE OF INSURANCE POLICIES AND OTHER SERVICING PROCEDURES
 
     Standard Hazard Insurance; Flood Insurance. Except as otherwise specified
in the related Prospectus Supplement, the Master Servicer will be required to
maintain or to cause the borrower on each Loan to maintain or will use its best
reasonable efforts to cause each Servicer of a Loan to maintain a standard
hazard insurance policy providing coverage of the standard form of fire
insurance with extended coverage for certain other hazards as is customary in
the state in which the property securing the related Loan is located. See
'Description of Mortgage and Other Insurance' herein. Unless otherwise specified
in the related Prospectus Supplement, coverage will be in an amount at least
equal to the greater of (i) the amount necessary to avoid the enforcement of any
co-insurance clause contained in the policy or (ii) the outstanding principal
balance of the related Loan. The Master Servicer will also maintain on REO
Property that secured a defaulted Loan and that has been acquired upon
foreclosure, deed in lieu of foreclosure, or repossession, a standard hazard
insurance policy in an amount that is at least equal to the maximum insurable
value of such REO Property. No earthquake or other additional insurance will be
required of any borrower or will be maintained on REO Property acquired in
respect of a defaulted Loan, other than pursuant to such applicable laws and
regulations as shall at any time be in force and shall require such additional
insurance. When, at the time of origination of a Loan or at any time during the
term of the Loan the Master Servicer or the related Servicer determines that the
related Mortgaged Property is located in an area identified on a Flood Hazard
Boundary Map or Flood Insurance Rate Map issued by the Flood Emergency
Management Agency as having special flood hazards and flood insurance has been
made available, the borrower will cause to be maintained a flood insurance
policy meeting the requirements of the current guidelines of the Federal
Insurance Administration with a generally acceptable insurance carrier, in an
amount representing coverage not less than the lesser of (i) the outstanding
principal balance of the Loan or (ii) the maximum amount of insurance which is
available under the National Flood Insurance Act of 1968, the Flood Disaster
Protection Act of 1983 or the National Flood Insurance Reform Act of 1994, as
amended. The Pooling and Servicing Agreement or Servicing Agreement will
obligate the Mortgagor to obtain and maintain all requisite flood insurance
coverage at the Mortgagor's cost and expense, and on the Mortgagor's failure to
do so, authorizes the Master Servicer or Servicer to obtain and maintain such
coverage at the Mortgagor's cost and expense and to seek reimbursement therefor
from the Mortgagor.
 
     Any amounts collected by the Master Servicer or the Servicer, as the case
may be, under any such policies of insurance (other than amounts to be applied
to the restoration or repair of the Mortgaged Property, released to the borrower
in accordance with normal servicing procedures or used to reimburse the Master
Servicer for amounts to which it is entitled to reimbursement) will be deposited
in the Collection Account. In the event that the Master Servicer obtains and
maintains a blanket policy insuring against hazard losses on all of the Loans,
written by an insurer then acceptable to each Rating Agency which assigns a
rating to such Series, it will conclusively be deemed to have satisfied its
obligations to cause to be maintained a standard hazard insurance policy for
each Loan or related REO Property. This blanket policy may contain a deductible
clause, in which case the Master Servicer will, in the event that there has been
a loss that would have been covered by such policy absent such deductible
clause, deposit in the Collection Account the amount not otherwise payable under
the blanket policy because of the application of such deductible clause.
 
     The Depositor will not require that a standard hazard or flood insurance
policy be maintained on the Cooperative Dwelling relating to any Cooperative
Loan. Generally, the Cooperative itself is responsible for maintenance of hazard
insurance for the property owned by the cooperative and the tenant-stockholders
of that cooperative do not maintain individual hazard insurance policies. To the
extent, however, that a Cooperative and the related borrower on a Cooperative
Loan do not maintain such insurance or do not maintain adequate coverage or any
insurance proceeds are not applied to the restoration of damaged property, any
damage to such borrower's Cooperative Dwelling or such Cooperative's building
could significantly reduce the value of the collateral securing such Cooperative
Loan to the extent not covered by other credit support. Similarly, the Depositor
will not require that a standard hazard or flood insurance policy be maintained
on a Condominium Unit relating to any Condominium Loan. Generally, the
Condominium Association is responsible for maintenance of hazard insurance
insuring the entire Condominium building (including each individual Condominium
Unit), and the owner(s) of an individual Condominium Unit do not maintain
separate hazard insurance policies. To the extent, however, that a Condominium
Association and the related borrower on a Condominium Loan do not maintain such
insurance or do not maintain adequate coverage or any insurance proceeds are not
applied to the restoration of damaged property, any damage to such borrower's
Condominium
 
                                       38
 

<PAGE>

<PAGE>
Unit or the related Condominium Building could significantly reduce the value of
the collateral securing such Condominium Loan to the extent not covered by other
credit support.
 
     Special Hazard Insurance Policy. If, and to the extent specified in the
related Prospectus Supplement, the Master Servicer will maintain a special
hazard insurance policy, in the amount set forth in the related Prospectus
Supplement, in full force and effect with respect to the Loans unless otherwise
specified in the related Prospectus Supplement, the special hazard insurance
policy will provide for a fixed premium rate based on the declining aggregate
outstanding principal balance of the Loans. The Master Servicer will agree to
pay the premium for any special hazard insurance policy on a timely basis. If
the special hazard insurance policy is canceled or terminated for any reason
(other than the exhaustion of total policy coverage), the Master Servicer will
exercise its best reasonable efforts to obtain from another insurer a
replacement policy comparable to the special hazard insurance policy with a
total coverage which is equal to the then existing coverage of the terminated
special hazard insurance policy; provided that if the cost of any such
replacement policy is greater than the cost of the terminated special hazard
insurance policy, the amount of coverage under the replacement policy will,
unless otherwise specified in the related Prospectus Supplement, be reduced to a
level such that the applicable premium does not exceed 150% of the cost of the
special hazard insurance policy that was replaced. Any amounts collected by the
Master Servicer under the special hazard insurance policy in the nature of
insurance proceeds will be deposited in the Collection Account (net of amounts
to be used to repair, restore or replace the related property securing the Loan
or to reimburse the Master Servicer (or a Servicer) for related amounts owed to
it). Certain characteristics of the special hazard insurance policy are
described under 'Description of Mortgage and Other Insurance -- Hazard Insurance
on the Loans.'
 
     Primary Mortgage Insurance. To the extent described in the related
Prospectus Supplement, the Master Servicer will be required to use its best
reasonable efforts to keep, or to cause each Servicer to keep, in full force and
effect, a primary mortgage insurance policy with respect to each Conventional
Loan secured by Single Family Property for which such coverage is required for
as long as the related mortgagor is obligated to maintain such primary mortgage
insurance under the terms of the related Loan. The Master Servicer will not
cancel or refuse to renew any such primary mortgage insurance policy in effect
at the date of the initial issuance of the Securities that is required to be
kept in force unless a replacement primary mortgage insurance policy for such
cancelled or nonrenewed policy is maintained with a Qualified Insurer.
 
     Primary insurance policies will be required with respect to Manufactured
Home Loans only to the extent described in the related Prospectus Supplement. If
primary mortgage insurance is to be maintained with respect to Manufactured Home
Loans, the Master Servicer will be required to maintain such insurance as
described above. For further information regarding the extent of coverage under
a primary mortgage insurance policy, see 'Description of Mortgage and Other
Insurance -- Mortgage Insurance on the Loans.'
 
     FHA Insurance and VA Guarantees. To the extent specified in the related
Prospectus Supplement, all or a portion of the Loans may be insured by the FHA
or guaranteed by the VA. The Master Servicer will be required to take such steps
as are reasonably necessary to keep such insurance and guarantees in full force
and effect. See 'Description of Mortgage and Other Insurance -- Mortgage
Insurance on the Loans.'
 
     Pool Insurance Policy. If so specified in the related Prospectus
Supplement, the Master Servicer will be obligated to use its best reasonable
efforts to maintain a pool insurance policy with respect to the Loans in the
amount and with the coverage described in the related Prospectus Supplement.
Unless otherwise specified in the related Prospectus Supplement, the pool
insurance policy will provide for a fixed premium rate on the declining
aggregate outstanding principal balance of the Loans. The Master Servicer will
be obligated to pay the premiums for such pool insurance policy on a timely
basis.
 
     The Prospectus Supplement will identify the pool insurer for the related
Series of Securities. If the pool insurer ceases to be a Qualified Insurer
because it is not approved as an insurer by FHLMC or FNMA or because its
claims-paying ability is no longer rated in the category required by the related
Prospectus Supplement, the Master Servicer will be obligated to review, no less
often than monthly, the financial condition of the pool insurer to determine
whether recoveries under the pool insurance policy are jeopardized by reason of
the financial condition of the pool insurer. If the Master Servicer determines
that recoveries may be so jeopardized or if the pool insurer ceases to be
qualified under applicable law to transact a mortgage guaranty insurance
business, the Master Servicer will exercise its best reasonable efforts to
obtain from another Qualified Insurer a comparable replacement pool insurance
policy with a total coverage equal to the then outstanding coverage of the pool
insurance policy to be replaced; provided that, if the premium rate on the
replacement
 
                                       39
 

<PAGE>

<PAGE>
policy is greater than that of the existing pool insurance policy, then the
coverage of the replacement policy will, unless otherwise specified in the
related Prospectus Supplement, be reduced to a level such that its premium rate
does not exceed 150% of the premium rate on the pool insurance policy to be
replaced. Payments made under a pool insurance policy will be deposited into the
Collection Account (net of expenses of the Master Servicer or any related
unreimbursed Advances or unpaid Servicing Fee). Certain characteristics of the
pool insurance policy are described under 'Description of Mortgage and Other
Insurance -- Mortgage Insurance on the Loans.'
 
     Bankruptcy Bond. If so specified in the related Prospectus Supplement, the
Master Servicer will be obligated to use its best reasonable efforts to obtain
and thereafter maintain a bankruptcy bond or similar insurance or guaranty in
full force and effect throughout the term of the related Agreement, unless
coverage thereunder has been exhausted through payment of claims. If so
specified in the Prospectus Supplement, the Master Servicer will be required to
pay from its servicing compensation the premiums for the bankruptcy bond on a
timely basis. Coverage under the bankruptcy bond may be cancelled or reduced by
the Master Servicer at any time, provided that such cancellation or reduction
does not adversely affect the then current rating of the related Series of
Securities. See 'Description of Mortgage and Other Insurance -- Bankruptcy Bond'
herein.
 
PRESENTATION OF CLAIMS; REALIZATION UPON DEFAULTED LOANS
 
     The Master Servicer, on behalf of the Trustee and the Securityholders, will
be required to present or cause to be presented, claims with respect to any
standard hazard insurance policy, pool insurance policy, special hazard
insurance policy, bankruptcy bond, or primary mortgage insurance policy, and to
the FHA and the VA, if applicable in respect of any FHA insurance or VA
guarantee respecting defaulted Mortgage Loans.
 
     The Master Servicer will use its reasonable best efforts to foreclose upon,
repossess or otherwise comparably convert the ownership of the real properties
securing such of the related Loans as come into and continue in default and as
to which no satisfactory arrangements can be made for collection of delinquent
payments. In connection with such foreclosure or other conversion, the Master
Servicer will follow such practices and procedures as it deems necessary or
advisable and as are normal and usual in its servicing activities with respect
to comparable loans serviced by it. However, the Master Servicer will not be
required to expend its own funds in connection with any foreclosure or towards
the restoration of the property unless it determines: (i) that such restoration
or foreclosure will increase the Liquidation Proceeds in respect of the related
Mortgage Loan available to the Securityholders after reimbursement to itself for
such expenses and (ii) that such expenses will be recoverable by it either
through Liquidation Proceeds or the proceeds of insurance. Notwithstanding
anything to the contrary herein, in the case of a Trust Fund for which a REMIC
election or elections have been made, the Master Servicer shall not liquidate
any collateral acquired through foreclosure later than two years after the
acquisition of such collateral, unless a longer period of time is necessary for
the orderly liquidation of the collateral and the Master Servicer has obtained
from the Internal Revenue Service (the 'IRS') an extension of the two year
period within which it would otherwise be required to liquidate the collateral.
While the holder of Mortgaged Property acquired through foreclosure can often
maximize its recovery by providing financing to a new purchaser, the Trust Fund
will have no ability to do so and neither the Master Servicer nor any Servicer
will be required to do so.
 
     With respect to a Mortgage Loan in default, the Master Servicer may pursue
foreclosure (or similar remedies) concurrently with pursuing any remedy for a
breach of a representation and warranty. However, the Master Servicer is not
required to continue to pursue both such remedies if it determines that one such
remedy is more likely to result in a greater recovery. If such Mortgage Loan is
an Additional Collateral Loan, the Master Servicer (or the related Servicer, if
the lien on the Additional Collateral for such Additional Collateral Loan is not
assigned to the Trustee on behalf of the Securityholders) may proceed against
the related Mortgaged Property or the related Additional Collateral first or may
proceed against both concurrently (as permitted by applicable law and the terms
under which such Additional Collateral is held, including any third-party
guarantee). Upon the first to occur of final liquidation (by foreclosure or
otherwise) and a repurchase or substitution pursuant to a breach of a
representation and warranty, such Mortgage Loan will be removed from the related
Trust Fund if it has not been removed previously.
 
     If any property securing a defaulted Loan is damaged and proceeds, if any,
from the related standard hazard insurance policy or the applicable special
hazard insurance policy, if any, are insufficient to restore the damaged
property to a condition sufficient to permit recovery under any pool insurance
policy or any primary mortgage insurance policy, FHA insurance, or VA guarantee,
neither the Master Servicer nor any Servicer will be required
 
                                       40
 

<PAGE>

<PAGE>
to expend its own funds to restore the damaged property unless it determines (i)
that such restoration will increase the Liquidation Proceeds in respect of the
Loan after reimbursement of the expenses incurred by such Servicer or the Master
Servicer and (ii) that such expenses will be recoverable by it through proceeds
of the sale of the property or proceeds of the related pool insurance policy or
any related primary mortgage insurance policy, FHA insurance, or VA guarantee.
 
     As to collateral securing a Cooperative Loan, any prospective purchaser
will generally have to obtain the approval of the board of directors of the
relevant cooperative before purchasing the shares and acquiring rights under the
proprietary lease or occupancy agreement securing that Cooperative Loan. See
'Certain Legal Aspects of Loans -- Foreclosure on Shares of Cooperatives'
herein. This approval is usually based on the purchaser's income and net worth
and numerous other factors. Although the Cooperative's approval is unlikely to
be unreasonably withheld or delayed, the necessity of acquiring such approval
could limit the number of potential purchasers for those shares and otherwise
limit the Trust Fund's ability to sell and realize the value of those shares.
 
     With respect to a defaulted Manufactured Home Loan, the value of the
related Manufactured Home can be expected to be less on resale than a new
Manufactured Home. To the extent equity does not cushion the loss in market
value, and such loss is not covered by other credit support, a loss may be
experienced by the Trust Fund.
 
     Notwithstanding the foregoing, unless otherwise specified in the related
Prospectus Supplement, the Master Servicer may not acquire title to any
Multifamily Property securing a Mortgage Loan or take any other action that
would cause the related Trustee, for the benefit of Securityholders of the
related Series, or any other specified person to be considered to hold title to,
to be a 'mortgagee-in-possession' of, or to be an 'owner' or an 'operator' of
such Mortgaged Property within the meaning of certain federal environmental
laws, unless the Master Servicer has previously determined, based on a report
prepared by a person who regularly conducts environmental audits (which report
will be an expense of the Trust Fund), that either:
 
          (i) the Mortgaged Property is in compliance with applicable
     environmental laws and regulations or, if not, that taking such actions as
     are necessary to bring the Mortgaged Property into compliance therewith is
     reasonably likely to produce a greater recovery on a present value basis
     than not taking such actions; and
 
          (ii) there are no circumstances or conditions present at the Mortgaged
     Property that have resulted in any contamination for which investigation,
     testing, monitoring, containment, clean-up or remediation could be required
     under any applicable environmental laws and regulations or, if such
     circumstances or conditions are present for which any such action could be
     required, taking such actions with respect to the Mortgaged Property is
     reasonably likely to produce a greater recovery on a present value basis
     than not taking such actions. See 'Certain Legal Aspects of Mortgage
     Loans -- Environmental Legislation.'
 
     With respect to a Loan secured by a Multifamily Property, the market value
of any property obtained in foreclosure or by deed in lieu of foreclosure will
be based substantially on the operating income obtained by renting the dwelling
units. As a default on a Loan secured by Multifamily Property is likely to have
occurred because operating income, net of expenses, is insufficient to make debt
service payments on the related Loan, it can be anticipated that the market
value of such property will be less than anticipated when such Loan was
originated. To the extent that equity does not cushion the loss in market value
and such loss is not covered by other credit support, a loss may be experienced
by the related Trust Fund.
 
ENFORCEMENT OF DUE-ON-SALE CLAUSES
 
     Unless otherwise specified in the related Prospectus Supplement for a
Series, when any Mortgaged Property is about to be conveyed by the borrower, the
Master Servicer will, to the extent it has knowledge of such prospective
conveyance and prior to the time of the consummation of such conveyance,
exercise the Trustee's right to accelerate the maturity of such Loan under the
applicable 'due-on-sale' clause, if any, unless the Master Servicer reasonably
believes that such clause is not enforceable under applicable law or if the
enforcement of such clause would result in loss of coverage under any primary
mortgage insurance policy. If such conditions are not met or the Master Servicer
reasonably believes that enforcement of a due-on-sale clause will not be
enforceable, the Master Servicer is authorized to accept from or enter into a
substitution or assumption agreement, on behalf of the Trustee, with the person
to whom such property has been or is about to be conveyed, pursuant to which
such person becomes liable under the Loan and pursuant to which the original
borrower is released from liability and such person is substituted as the
borrower and becomes liable under the
 
                                       41
 

<PAGE>

<PAGE>
Loan. Any fee collected in connection with an assumption will be retained by the
Master Servicer as additional servicing compensation. The terms of a Loan may
not be changed in connection with a substitution or assumption.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     Except as otherwise provided in the related Prospectus Supplement, the
Master Servicer or any Servicer will be entitled to a servicing fee in an amount
to be determined as specified in the related Prospectus Supplement. The
servicing fee may be fixed or variable, as specified in the related Prospectus
Supplement. The Master Servicer or any Servicer will be entitled to additional
servicing compensation, unless otherwise specified in the related Prospectus
Supplement, in the form of assumption fees, late payment charges, or excess
proceeds following disposition of property in connection with defaulted Loans
and as otherwise specified herein.
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer will pay the fees of the Servicers, if any, and certain expenses
incurred in connection with the servicing of the Loans, including, without
limitation, the payment of the fees and expenses of the Trustee and independent
accountants, payment of insurance policy premiums and the cost of credit
support, if any, payment of expenses incurred in enforcing the obligations of
Servicers and Sellers and in the preparation of reports to Securityholders.
Certain of these expenses may be reimbursable pursuant to the terms of the
related Agreement from Liquidation Proceeds and the proceeds of insurance
policies and, in the case of enforcement of the obligations of Servicers and
Sellers, from any recoveries in excess of amounts due with respect to the
related Loans or from specific recoveries of costs.
 
     The Master Servicer will be entitled to reimbursement for certain expenses
incurred by it in connection with the liquidation of defaulted Loans. The
related Trust Fund will suffer no loss by reason of such expenses to the extent
claims are paid under related insurance policies or from the Liquidation
Proceeds. If claims are either not made or paid under the applicable insurance
policies or if coverage thereunder has been exhausted, the related Trust Fund
will suffer a loss to the extent that Liquidation Proceeds, after reimbursement
of the Master Servicer's expenses, are less than the outstanding principal
balance of and unpaid interest on the related Loan which would be distributable
to Securityholders. In addition, the Master Servicer will be entitled to
reimbursement of expenditures incurred by it in connection with the restoration
of property securing a defaulted Loan, such right of reimbursement being prior
to the rights of the Securityholders to receive any related proceeds of
insurance policies, Liquidation Proceeds or amounts derived from other forms of
credit support. The Master Servicer is also entitled to reimbursement from the
Collection Account and the Certificate Account for Advances.
 
     Unless otherwise provided in the Prospectus Supplement, the rights of the
Master Servicer to receive funds from the Collection Account or the Certificate
Account for a Series, whether as the Servicing Fee or other compensation, or for
the reimbursement of Advances, expenses or otherwise, are not subordinate to the
rights of Securityholders of such Series.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Pooling and Servicing Agreement and each Servicing Agreement will
provide for delivery (on or before a specified date in each year) to the Trustee
of an annual statement signed by an officer of the Master Servicer, unless
otherwise specified in the related Prospectus Supplement, to the effect that the
Master Servicer has complied in all material respects with the minimum servicing
standards set forth in the Uniform Single Attestation Program for Mortgage
Bankers and has fulfilled in all material respects its obligations under the
related Agreement throughout the preceding year or, if there has been material
noncompliance with such servicing standards or a material default in the
fulfillment of any such obligation, such statement shall include a description
of such noncompliance or specify each such known default, as the case may be,
and the nature and status thereof. Such statement may be provided as a single
form making the required statements as to more than one Agreement.
 
     Each Pooling and Servicing Agreement and each Servicing Agreement will also
provide that on or before a specified date in each year, beginning the first
such date that is at least a specified number of months after the Cut-off Date,
a firm of independent public accountants will furnish a report to the Depositor
and the Trustee stating the opinion of such firm that, unless otherwise
specified in the related Prospectus Supplement, on the
 
                                       42
 

<PAGE>

<PAGE>
basis of an examination by such firm conducted substantially in accordance with
standards established by the American Institute of Certified Public Accountants,
the assertion by management of the Master Servicer regarding the Master
Servicer's compliance with the minimum servicing standards set forth in the
Uniform Single Attestation Program for Mortgage Bankers during the preceding
year is fairly stated in all material respects, subject to such exceptions and
other qualifications that, in the opinion of such firm, such accounting
standards require it to report. In rendering its statement such firm may rely,
as to the matters relating to the direct servicing of mortgage loans by
Servicers, upon comparable statements for examinations conducted by independent
public accountants substantially in accordance with standards established by the
American Institute of Certified Public Accountants (rendered within one year of
such statement) with respect to those Servicers which also have been the subject
of such an examination.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The Master Servicer for each Series will be identified in the related
Prospectus Supplement. The Master Servicer may be an affiliate of the Depositor
and may have other business relationships with the Depositor and its affiliates.
 
     Unless otherwise provided in the related Prospectus Supplement, the Master
Servicer may not resign from its obligations and duties under the related
Pooling and Servicing Agreement or Servicing Agreement except upon its
determination that its duties thereunder are no longer permissible under
applicable law or except in connection with a permitted transfer of servicing.
No such resignation will become effective until the Trustee or a successor
Master Servicer has assumed the Master Servicer's obligations and duties under
the related Agreement.
 
     In the event of an Event of Default under the related Pooling and Servicing
Agreement or Servicing Agreement, the Master Servicer may be replaced by the
Trustee or a successor Master Servicer. See 'The Agreements -- Rights upon
Events of Default' herein.
 
     Unless otherwise provided in the Prospectus Supplement, the Master Servicer
has the right, with the consent of the Trustee, which consent shall not be
unreasonably withheld, to assign its rights and delegate its duties and
obligations under the Pooling and Servicing Agreement or Servicing Agreement for
each Series; provided that the purchaser or transferee accepting such assignment
or delegation (i) is qualified to sell loans to and service mortgage loans for
FNMA or FHLMC; (ii) has a net worth of not less than $10,000,000; (iii) is
acceptable to each Rating Agency for purposes of maintaining its then-current
ratings of the Securities; (iv) is reasonably acceptable to the Trustee; and (v)
executes and delivers to the Depositor and the Trustee an agreement, in form and
substance reasonably satisfactory to the Trustee, which contains an assumption
by such purchaser or transferee of the due and punctual performance and
performed or observed by the Master Servicer under the related Pooling and
Servicing Agreement or Servicing Agreement from and after the date of such
agreement. To the extent that the Master Servicer transfers its obligations to a
wholly-owned subsidiary or affiliate, such subsidiary or affiliate need not
satisfy the criteria set forth above. However, in such instance the assigning
Master Servicer will remain liable for the servicing obligations under the
related Agreement. Any entity into which the Master Servicer is merged or
consolidated or any successor corporation resulting from any merger, conversion
or consolidation will succeed to the Master Servicer's obligations under the
related Agreement, provided that such successor or surviving entity meets the
requirements for a successor Master Servicer set forth above.
 
     Each Pooling and Servicing Agreement and each Servicing Agreement will also
provide that neither the Master Servicer, the Depositor, nor any director,
officer, employee or agent of the Master Servicer or the Depositor, will be
under any liability to the related Trust Fund or the Securityholders for any
action taken or for failing to take any action in good faith pursuant to the
related Agreement or for errors in judgment; provided, however, that neither the
Master Servicer, the Depositor, nor any such person will be protected against
any breach of warranty or representations made by such party under the related
Agreement or the failure to perform its obligations in compliance with any
standard of care set forth in the related Agreement or liability which would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in the performance of their duties or by reason of reckless disregard of their
obligations and duties thereunder. Each Pooling and Servicing Agreement and each
Servicing Agreement will further provide that the Master Servicer, the Depositor
and any director, officer, employee or agent of the Master Servicer or the
Depositor is entitled to indemnification from the related Trust Fund and will be
held harmless against any loss, liability or expense incurred in
 
                                       43
 

<PAGE>

<PAGE>
connection with any legal action relating to the related Agreement or the
Securities, other than any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or negligence in the performance of duties
thereunder or by reason of reckless disregard of obligations and duties
thereunder. In addition, the related Agreement provides that neither the Master
Servicer nor the Depositor is under any obligation to appear in, prosecute or
defend any legal action which is not incidental to its servicing
responsibilities under the related Agreement which, in its opinion, may involve
it in any expense or liability. The Master Servicer or the Depositor may, in its
discretion, undertake any such action which it may deem necessary or desirable
with respect to the related Agreement and the rights and duties of the parties
thereto and the interests of the Securityholders thereunder. In such event, the
legal expenses and costs of such action and any liability resulting therefrom
will be expenses, costs, and liabilities of the Trust Fund and the Master
Servicer or the Depositor will be entitled to be reimbursed therefor out of the
Collection Account (or the Certificate Account, if applicable).
 
                                 CREDIT SUPPORT
 
GENERAL
 
     For any Series, credit support may be provided with respect to one or more
Classes thereof or the related Mortgage Assets. Credit support may be in the
form of a letter of credit, the subordination of one or more Classes of the
Securities of such Series, subordination created through overcollateralization,
the establishment of one or more reserve funds, use of a pool insurance policy,
bankruptcy bond, repurchase bond or special hazard insurance policy, financial
guarantee insurance, the use of cross-support features or another method of
credit support described in the related Prospectus Supplement, or any
combination of the foregoing, in any case, in such amounts and having such terms
and conditions as are acceptable to each Rating Agency which assigns a rating to
the Securities of the related Series. Credit support may also be provided in the
form of an insurance policy covering the risk of collection and adequacy of any
Additional Collateral provided in connection with any Additional Collateral
Loan, subject to the limitations set forth in any such insurance policy.
 
     Unless otherwise specified in the related Prospectus Supplement for a
Series, the credit support 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 at the Security Interest Rate. If losses occur
which exceed the amount covered by credit support or which are not covered by
credit support, such losses will be borne by the Securityholders. If credit
support is provided with respect to a Series, the related Prospectus Supplement
will include a description of (a) the amount payable under such credit support,
(b) any conditions to payment thereunder not otherwise described herein, (c) the
conditions under which the amount payable under such credit support may be
reduced and under which such credit support may be terminated or replaced and
(d) the material provisions of any agreement relating to such credit support.
Additionally, the related Prospectus Supplement will set forth certain
information with respect to the issuer of any third-party credit support,
including (a) a brief description of its principal business activities, (b) its
principal place of business, place of incorporation and the jurisdiction under
which it is chartered or licensed to do business, (c) if applicable, the
identity of regulatory agencies which exercise primary jurisdiction over the
conduct of its business and (d) its total assets, and its stockholders' or
policyholders' surplus, if applicable, as of the date specified in the
Prospectus Supplement.
 
SUBORDINATE SECURITIES; SUBORDINATION RESERVE FUND
 
     If so specified in the related Prospectus Supplement, one or more Classes
of a Series may be Subordinate Securities. If so specified in the related
Prospectus Supplement, the rights of the Subordinate Securityholders to receive
distributions of principal and interest from the Certificate Account on any
Distribution Date will be subordinated to such rights of the Senior
Securityholders to the extent of the then applicable Subordinated Amount as
defined in the related Prospectus Supplement. The Subordinated Amount will
decrease whenever amounts otherwise payable to the Subordinate Securityholders
are paid to the Senior Securityholders (including amounts withdrawn from the
Subordination Reserve Fund, if any, and paid to the Senior Securityholders), and
will (unless otherwise specified in the related Prospectus Supplement) increase
whenever there is distributed to the Subordinate Securityholders amounts in
respect of which subordination payments have previously been paid to the Senior
Securityholders (which will occur when subordination payments in respect of
delinquencies and certain other deficiencies have been recovered).
 
                                       44

     A Series may include a Class of Subordinate Securities entitled to receive
cash flows remaining after distributions made to all other Classes. Such right
will effectively be subordinate to the rights of other Securityholders, but will
not be limited to the Subordinated Amount. If so specified in the related
Prospectus Supplement, the subordination of a Class may apply only in the event
of certain types of losses not covered by insurance policies or other credit
support, such as losses arising from damage to property securing a Loan not
covered by standard hazard insurance policies, losses resulting from the
bankruptcy of a borrower and application of certain provisions of the Bankruptcy
Code, or losses resulting from the denial of insurance coverage due to fraud or
misrepresentation in connection with the origination of a Loan.
 
     With respect to any Series which includes one or more Classes of
Subordinate Securities, a Subordination Reserve Fund may be established if so
specified in the related Prospectus Supplement. The Subordination Reserve Fund,
if any, will be funded with cash, a letter of credit, a demand note or Eligible
Reserve Fund Investments, or by the retention of amounts of principal or
interest otherwise payable to Holders of Subordinate Securities, or both, as
specified in the related Prospectus Supplement. The Subordination Reserve Fund
will not be a part of the Trust Fund, unless otherwise specified in the related
Prospectus Supplement. If the Subordination Reserve Fund is not a part of the
Trust Fund, the Trustee will have a security interest therein on behalf of the
Senior Securityholders. Moneys will be withdrawn from the Subordination Reserve
Fund to make distributions of principal of or interest on Senior Securities
under the circumstances set forth in the related Prospectus Supplement.
 
     Moneys deposited in any Subordination Reserve Fund will be invested in
Eligible Reserve Fund Investments. Unless otherwise specified in the related
Prospectus Supplement, any reinvestment income or other gain from such
investments will be credited to the Subordination Reserve Fund for such Series,
and any loss resulting from such investments will be charged to such
Subordination Reserve Fund. Amounts in any Subordination Reserve Fund in excess
of the Required Reserve Fund Balance may be periodically released to the
Subordinate Securityholders under the conditions and to the extent specified in
the related Prospectus Supplement. Additional information concerning any
Subordination Reserve Fund will be set forth in the related Prospectus
Supplement, including the amount of any initial deposit to such Subordination
Reserve Fund, the Required Reserve Fund Balance to be maintained therein, the
purposes for which funds in the Subordination Reserve Fund may be applied to
make distributions to Senior Securityholders and the employment of reinvestment
earnings on amounts in the Subordination Reserve Fund, if any.
 
OVERCOLLATERALIZATION
 
     If so specified in the related Prospectus Supplement, subordination may be
provided by one or more Classes of Senior Securities through
overcollateralization; i.e., by having a greater amount of aggregate principal
balance of the Mortgage Assets for a Series than the aggregate principal balance
of the Securities of such Series. Such subordination may exist on the Closing
Date or may be effected through the allocation of interest payments on the Loans
to reduce the principal balances of certain Classes of Securities.
 
     In a Series with overcollateralization, the allocation of losses to the
Securities is handled through the priority of payment process, first by interest
that otherwise would pay down principal on the Securities, and then such losses
would be allocated to the Senior Securities only if the principal balance of the
Mortgage Loans was reduced to less than the principal balance of the Senior
Securities. If so specified in the related Prospectus Supplement, the level of
overcollateralization required under the provisions of the related Pooling and
Servicing Agreement or Indenture will be subject to various tests based
primarily on the loss and delinquency experience of the related Mortgage Assets,
and will be raised and lowered accordingly.
 
CROSS-SUPPORT FEATURES
 
     If the Mortgage Assets for a Series are divided into separate Asset Groups,
the beneficial ownership of which is evidenced by a separate Class or Classes of
a Series, credit support may be provided by a cross-support feature which
requires that distributions be made on Senior Securities evidencing the
beneficial ownership of one Asset Group prior to distributions on Subordinate
Securities evidencing the beneficial ownership interest in another Asset Group
within the Trust Fund. The related Prospectus Supplement for a Series which
includes a cross-support feature will describe the manner and conditions for
applying such cross-support feature.
 
                                       45

INSURANCE
 
     Credit support with respect to a Series may be provided by various forms of
insurance policies, subject to limits on the aggregate dollar amount of claims
that will be payable under each such insurance policy, with respect to all Loans
comprising or underlying the Mortgage Assets for a Series, or such of the Loans
as have certain characteristics. Such insurance policies include primary
mortgage insurance and standard hazard insurance and may, if specified in the
related Prospectus Supplement, include a pool insurance policy covering losses
in amounts in excess of coverage of any primary insurance policy, a special
hazard insurance policy covering certain risks not covered by standard hazard
insurance policies, a bankruptcy bond covering certain losses resulting from the
bankruptcy of a borrower and application of certain provisions of the Bankruptcy
Code, a repurchase bond covering the repurchase of a Loan for which mortgage
insurance or hazard insurance coverage has been denied due to misrepresentations
in connection with the organization of the related Loan, or other insurance
covering other risks associated with the particular type of Loan. See
'Description of Mortgage and Other Insurance.' Copies of the actual pool
insurance policy, special hazard insurance policy, bankruptcy bond or repurchase
bond, if any, relating to the Loans comprising the Mortgage Assets for a Series
will be filed with the Commission as an exhibit to a Current Report on Form 8-K
to be filed within 15 days of issuance of the Securities of the related Series.
 
LETTER OF CREDIT
 
     The letter of credit, if any, with respect to a Series of Securities will
be issued by the bank or financial institution specified in the related
Prospectus Supplement (the 'L/C Bank'). Under the letter of credit, the L/C Bank
will be obligated to honor drawings thereunder in an aggregate fixed dollar
amount, net of unreimbursed payments thereunder, equal to the percentage
specified in the related Prospectus Supplement of the aggregate principal
balance of the Loans on the related Cut-off Date or of one or more Classes of
Securities (the 'L/C Percentage'). If so specified in the related Prospectus
Supplement, the letter of credit may permit drawings in the event of losses not
covered by insurance policies or other credit support, such as losses arising
from damage not covered by standard hazard insurance policies, losses resulting
from the bankruptcy of a borrower and the application of certain provisions of
the Bankruptcy Code, or losses resulting from denial of insurance coverage due
to misrepresentations in connection with the origination of a Loan. The amount
available under the letter of credit will, in all cases, be reduced to the
extent of the unreimbursed payments thereunder. The obligations of the L/C Bank
under the letter of credit for each Series of Securities will expire at the
earlier of the date specified in the related Prospectus Supplement or the
termination of the Trust Fund. See 'Description of the Securities -- Optional
Termination' and 'The Agreements -- Termination.' A copy of the letter of credit
for a Series, if any, will be filed with the Commission as an exhibit to a
Current Report on Form 8-K to be filed within 15 days of issuance of the
Securities of the related Series.
 
FINANCIAL GUARANTEE INSURANCE
 
     Financial Guarantee Insurance, if any, with respect to a Series of
Securities will be provided by one or more insurance companies. Such Financial
Guarantee Insurance will guarantee, with respect to one or more Classes of
Securities of the related Series, timely distributions of interest and full
distributions of principal on the basis of a schedule of principal distributions
set forth in or determined in the manner specified in the related Prospectus
Supplement. If so specified in the related Prospectus Supplement, the Financial
Guarantee Insurance will also guarantee against any payment made to a
Securityholder which is subsequently recovered as a 'voidable preference'
payment under the Bankruptcy Code. A copy of the financial guarantee insurance
for a Series, if any, will be filed with the Commission as an exhibit to a
Current Report on Form 8-K to be filed with the Commission within 15 days of
issuance of the Securities of the related Series.
 
RESERVE FUNDS
 
     One or more Reserve Funds may be established with respect to a Series, in
which cash, a letter of credit, Eligible Reserve Fund Investments, a demand note
or a combination thereof, in the amounts, if any, so specified in the related
Prospectus Supplement will be deposited. The Reserve Funds for a Series may also
be funded over time by depositing therein a specified amount of the
distributions received on the related Mortgage Assets as specified in the
related Prospectus Supplement.
 
                                       46
 

<PAGE>

<PAGE>
     Amounts on deposit in any reserve fund for a Series, together with the
reinvestment income thereon, will be applied by the Trustee for the purposes, in
the manner, and to the extent specified in the related Prospectus Supplement. A
Reserve Fund may be provided to increase the likelihood of timely payments of
principal of and interest on the Securities, if required as a condition to the
rating of such Series by each Rating Agency rating such Series. If so specified
in the related Prospectus Supplement, Reserve Funds may be established to
provide limited protection, in an amount satisfactory to each Rating Agency
which assigns a rating to the Securities, against certain types of losses not
covered by insurance policies or other credit support, such as losses arising
from damage not covered by standard hazard insurance policies, losses resulting
from the bankruptcy of a borrower and the application of certain provisions of
the Bankruptcy Code or losses resulting from denial of insurance coverage due to
fraud or misrepresentation in connection with the origination of a Loan.
Following each Distribution Date amounts in such Reserve Fund in excess of any
required reserve fund balance may be released from the Reserve Fund under the
conditions and to the extent specified in the related Prospectus Supplement and
will not be available for further application by the Trustee.
 
     Moneys deposited in any Reserve Funds will be invested in Eligible Reserve
Fund Investments, except as otherwise specified in the related Prospectus
Supplement. Unless otherwise specified in the related Prospectus Supplement, any
reinvestment income or other gain from such investments will be credited to the
related Reserve Fund for such Series, and any loss resulting from such
investments will be charged to such Reserve Fund. However, such income may be
payable to the Master Servicer or a Servicer as additional servicing
compensation. See 'Servicing of Loans' and 'The Agreements -- Investment of
Funds.' The Reserve Fund, if any, for a Series will not be a part of the Trust
Fund unless otherwise specified in the related Prospectus Supplement.
 
     Additional information concerning any Reserve Fund will be set forth in the
related Prospectus Supplement, including the initial balance of such Reserve
Fund, the required Reserve Fund balance to be maintained, the purposes for which
funds in the Reserve Fund may be applied to make distributions to
Securityholders and use of investment earnings from the Reserve Fund, if any.

                  DESCRIPTION OF MORTGAGE AND OTHER INSURANCE
 
     The following descriptions of primary mortgage insurance policies, pool
insurance policies, special hazard insurance policies, standard hazard insurance
policies, bankruptcy bonds, repurchase bonds and other insurance and the
respective coverages thereunder are general descriptions only and do not purport
to be complete.
 
MORTGAGE INSURANCE ON THE LOANS
 
     General. Unless otherwise specified in the related Prospectus Supplement,
all Mortgage Loans that are Conventional Loans secured by Single Family Property
and which had initial Loan-to-Value Ratios of greater than 80% will be covered
by primary mortgage insurance policies providing coverage on the amount of each
such Mortgage Loan in excess of 75% of the original Appraised Value of the
related Mortgaged Property and remaining in force until the principal balance of
such Mortgage Loan is reduced to 80% of such original Appraised Value.
Multifamily Loans will not be covered by a primary mortgage insurance policy,
regardless of the related Loan-to-Value Ratio.
 
     A pool insurance policy will be obtained if so specified in the related
Prospectus Supplement to cover any loss (subject to limitations described
herein) occurring as a result of default by the borrowers to the extent not
covered by any primary mortgage insurance policy, FHA Insurance or VA Guarantee.
See 'Pool Insurance Policy' below. Neither the primary mortgage insurance
policies nor any pool insurance policy will insure against certain losses
sustained in the event of a personal bankruptcy of the borrower under a Mortgage
Loan. See 'Certain Legal Aspects of Loans' herein. Such losses will be covered
to the extent described in the related Prospectus Supplement by the bankruptcy
bond or other credit support, if any.
 
     To the extent that the primary mortgage insurance policies do not cover all
losses on a defaulted or foreclosed Mortgage Loan, and to the extent such losses
are not covered by the pool insurance policy or other credit support for such
Series, such losses, if any, would affect payments to Securityholders. In
addition, the pool insurance policy and primary mortgage insurance policies do
not provide coverage against hazard losses. See 'Hazard Insurance on the Loans'
below. Certain hazard risks will not be insured and the occurrence of such
hazards could adversely affect payments to the Securityholders.
 
     Primary Mortgage Insurance. While the terms and conditions of the primary
mortgage insurance policies issued by one primary mortgage guaranty insurer (a
'Primary Insurer') will differ from those in primary mortgage insurance policies
issued by other Primary Insurers, each primary mortgage insurance policy
generally will pay either: (i) the insured percentage of the loss on the related
Mortgaged Property; (ii) the entire amount of such loss, after receipt by the
Primary Insurer of good and merchantable title to, and possession of, the
Mortgaged Property; or (iii) at the option of the Primary Insurer under certain
primary mortgage insurance policies, the sum of the delinquent monthly payments
plus any advances made by the insured, both to the date of the claim payment
and, thereafter, monthly payments in the amount that would have become due under
the Mortgage Loan if it had not been discharged plus any advances made by the
insured until the earlier of (a) the date the Mortgage Loan would have been
discharged in full if the default had not occurred or (b) an approved sale. The
amount of the loss as calculated under a primary mortgage insurance policy
covering a Mortgage Loan will generally consist of the unpaid principal amount
of such Mortgage Loan and accrued and unpaid interest thereon and reimbursement
of certain expenses, less (i) rents or other payments collected or received by
the insured (other than the proceeds of hazard insurance) that are derived from
the related Mortgaged Property, (ii) hazard insurance proceeds in excess of the
amount required to restore such Mortgaged Property and which have not been
applied to the payment of the Mortgage Loan, (iii) amounts expended but not
approved by the Primary Insurer, (iv) claim payments previously made on such
Mortgage Loan and (v) unpaid premiums and certain other amounts.
 
     As conditions precedent to the filing or payment of a claim under a primary
mortgage insurance policy, in the event of default by the Mortgagor, the insured
will typically be required, among other things, to: (i) advance or discharge
(a) hazard insurance premiums and (b) as necessary and approved in advance by
the Primary Insurer, real estate taxes, protection and preservation expenses and
foreclosure and related costs; (ii) in the event of any physical loss or damage
to the Mortgaged Property, have the Mortgaged Property restored to at least its
condition at the effective date of the primary mortgage insurance policy
(ordinary wear and tear excepted); and (iii) tender to the Primary Insurer good
and merchantable title to, and possession of, the Mortgaged Property.
 
                                       48

<PAGE>
     The Pooling and Servicing Agreement or Servicing Agreement for a Series
generally will require that the Master Servicer or Servicer maintain, or cause
to be maintained, coverage under a primary mortgage insurance policy to the
extent such coverage was in place on the Cut-off Date. In the event that the
Depositor gains knowledge that, as of the Closing Date, a Mortgage Loan had a
Loan-to-Value Ratio at origination in excess of 80% and was not the subject of a
primary mortgage insurance policy (and was not included in any exception to such
standard disclosed in the related Prospectus Supplement) and that such Mortgage
Loan has a then current Loan-to-Value Ratio in excess of 80%, then the Master
Servicer or the Servicer is required to use its reasonable efforts to obtain and
maintain a primary mortgage insurance policy to the extent that such a policy is
obtainable at a reasonable price.
 
     Any primary mortgage insurance or primary credit insurance policies
relating to Loans secured by Manufactured Homes will be described in the related
Prospectus Supplement.
 
     FHA Insurance and VA Guarantees. The Housing Act authorizes various FHA
mortgage insurance programs. Some of the Mortgage Loans may be insured under
either Section 203(b), Section 234 or Section 235 of the Housing Act. Under
Section 203(b), FHA insures mortgage loans of up to 30 years' duration for the
purchase of one- to four-family dwelling units. Mortgage loans for the purchase
of condominium units are insured by FHA under Section 234. Loans insured under
these programs must bear interest at a rate not exceeding the maximum rate in
effect at the time the loan is made, as established by HUD, and may not exceed
specified percentages of the lesser of the appraised value of the property and
the sales price, less seller paid closing costs for the property, up to certain
specified maximums. In addition, FHA imposes initial investment minimums and
other requirements on mortgage loans insured under the Section 203(b) and
Section 234 programs.
 
     Under Section 235, assistance payments are paid by HUD to the mortgagee on
behalf of eligible mortgagors for as long as the mortgagors continue to be
eligible for the payments. To be eligible, a mortgagor must be part of a family,
have income within the limits prescribed by HUD at the time of initial
occupancy, occupy the property and meet requirements for recertification at
least annually.
 
     The regulations governing these programs provide that insurance benefits
are payable either (i) upon foreclosure (or other acquisition of possession) and
conveyance of the mortgaged premises to HUD or (ii) upon assignment of the
defaulted mortgage loan to HUD. The FHA insurance that may be provided under
these programs upon the conveyance of the home to HUD is equal to 100% of the
outstanding principal balance of the mortgage loan, plus accrued interest, as
described below, and certain additional costs and expenses. When entitlement to
insurance benefits results from assignment of the mortgage loan to HUD, the
insurance payment is computed as of the date of the assignment and includes the
unpaid principal amount of the mortgage loan plus mortgage interest accrued and
unpaid to the assignment date.
 
     When entitlement to insurance benefits results from foreclosure (or other
acquisition of possession) and conveyance, the insurance payment is equal to the
unpaid principal amount of the mortgage loan, adjusted to reimburse the
mortgagee for certain tax, insurance and similar payments made by it and to
deduct certain amounts received or retained by the mortgagee after default, plus
reimbursement not to exceed two-thirds of the mortgagee's foreclosure costs. Any
FHA insurance relating to Loans underlying a Series of Securities will be
described in the related Prospectus Supplement.
 
     The Servicemen's Readjustment Act of 1944, as amended, permits a veteran
(or, in certain instances, his or her spouse) to obtain a mortgage loan guaranty
by the VA covering mortgage financing of the purchase of a one-to four-family
dwelling unit to be occupied as the veteran's home at an interest rate not
exceeding the maximum rate in effect at the time the loan is made, as
established by HUD. The program has no limit on the amount of a mortgage loan,
requires no down payment from the purchaser and permits the guaranty of mortgage
loans with terms, limited by the estimated economic life of the property, up to
30 years. The maximum guaranty that may be issued by the VA under this program
is 50% of the original principal amount of the mortgage loan up to a certain
dollar limit established by the VA. The liability on the guaranty is reduced or
increased on a pro rata basis with any reduction or increase in the amount of
indebtedness, but in no event will the amount payable on the guaranty exceed the
amount of the original guaranty. Notwithstanding the dollar and percentage
limitations of the guaranty, a mortgagee will ordinarily suffer a monetary loss
only when the difference between the unsatisfied indebtedness and the proceeds
of a foreclosure sale of mortgaged premises is greater than the original
guaranty as adjusted. The VA may, at its option, and without regard to the
guaranty, make full payment to a mortgagee of the unsatisfied indebtedness on a
mortgage upon its assignment to the VA.
 
                                       49

     Since there is no limit imposed by the VA on the principal amount of a
VA-guaranteed mortgage loan but there is a limit on the amount of the VA
guaranty, additional coverage under a Primary Mortgage Insurance Policy may be
required by the Depositor for VA loans in excess of certain amounts. The amount
of any such additional coverage will be set forth in the related Prospectus
Supplement. Any VA guaranty relating to Loans underlying a Series of Securities
will be described in the related Prospectus Supplement.
 
     Pool Insurance Policy. If so specified in the related Prospectus
Supplement, the Master Servicer will be required to maintain the pool insurance
policy and to present or cause the Servicers, if any, to present claims
thereunder on behalf of the Trustee and the Securityholders. See 'Servicing of
Loans -- Maintenance of Insurance Policies and Other Servicing Procedures.'
Although the terms and conditions of pool insurance policies vary to some
degree, the following describes material aspects of such policies generally. The
related Prospectus Supplement will describe any provisions of a pool insurance
policy which are materially different from those described below.
 
     The responsibilities of the Master Servicer, the amount of claim for
benefits, the conditions precedent to the filing or payment of a claim, the
policy provisions and the payment of claims under a pool insurance policy are
generally similar to those described above for primary mortgage insurance
policies, subject to the aggregate limit on the amount of coverage. It may also
be a condition precedent to the payment of any claim under the pool insurance
policy that the insured maintain a primary mortgage insurance policy that is
acceptable to the pool insurer on all Mortgage Loans in the related Trust Fund
that have Loan-to-Value Ratios at the time of origination in excess of 80% and
that a claim under such primary mortgage insurance policy has been submitted and
settled. FHA Insurance and VA Guarantees will be deemed to be acceptable primary
insurance policies under the pool insurance policy. Assuming satisfaction of
these conditions, the pool insurer will pay to the insured the amount of the
loss which will generally be: (i) the amount of the unpaid principal balance of
the defaulted Mortgage Loan immediately prior to the sale of the Mortgaged
Property, (ii) the amount of the accumulated unpaid interest on such Mortgage
Loan to the date of claim settlement at the contractual rate of interest and
(iii) advances made by the insured as described above less certain payments. An
'approved sale' is (i) a sale of the Mortgaged Property acquired by the insured
because of a default by the borrower to which the pool insurer has given prior
approval, (ii) a foreclosure or trustee's sale of the Mortgaged Property at a
price exceeding the maximum amount specified by the pool insurer, (iii) the
acquisition of the Mortgaged Property under the primary mortgage insurance
policy by the mortgage insurer or (iv) the acquisition of the Mortgaged Property
by the pool insurer.
 
     As a condition precedent to the payment of any loss, the insured must
provide the pool insurer with good and merchantable title to the Mortgaged
Property. If any Mortgaged Property securing a defaulted Mortgage Loan is
damaged and the proceeds, if any, from the related standard hazard insurance
policy or the applicable special hazard insurance policy, if any, are
insufficient to restore the damaged Mortgaged Property to a condition sufficient
to permit recovery under the pool insurance policy, the Master Servicer will not
be required to expend its own funds to restore the damaged property unless it
determines (i) that such restoration will increase the proceeds to the
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.
 
     The original amount of coverage under the pool insurance policy will be
reduced over the life of the Securities by the aggregate net dollar amount of
claims paid less the aggregate net dollar amount realized by the pool insurer
upon disposition of all foreclosed Mortgaged Properties covered thereby. The
amount of claims paid includes certain expenses incurred by the Master Servicer
as well as accrued interest at the applicable interest rate on delinquent
Mortgage Loans to the date of payment of the claim. See 'Certain Legal Aspects
of Loans' herein. Accordingly, if aggregate net claims paid under a pool
insurance policy reach the original policy limit, coverage under the pool
insurance policy will lapse and any further losses will be borne by the Trust
Fund, and thus will affect adversely payments on the Securities. In addition,
the exhaustion of coverage under any pool insurance policy may affect the Master
Servicer's or Servicer's willingness or obligation to make Advances. If the
Master Servicer or a Servicer determines that an Advance in respect of a
delinquent Loan would not be recoverable from the proceeds of the liquidation of
such Loan or otherwise, it will not be obligated to make an advance respecting
any such delinquency since the Advance would not be ultimately recoverable by
it. See 'Servicing of Loans -- Advances and Limitations Thereon.'

     Mortgage Insurance with Respect to Manufactured Home Loans. A Manufactured
Home Loan may be an FHA Loan or a VA Loan. Any primary mortgage or similar
insurance and any pool insurance policy with respect to Manufactured Home Loans
will be described in the related Prospectus Supplement.
 
HAZARD INSURANCE ON THE LOANS
 
     Standard Hazard Insurance Policies for Mortgage Loans. The terms of the
Mortgage Loans require each Mortgagor to maintain a hazard insurance policy
covering the related Mortgaged Property and providing for coverage at least
equal to that of the standard form of fire insurance policy with extended
coverage customary in the state in which the property is located. Such coverage
generally will be in an amount equal to the lesser of the principal balance of
such Mortgage Loan or 100% of the insurable value of the improvements securing
the Mortgage Loan. The Pooling and Servicing Agreement or Servicing Agreement
will provide that the Master Servicer or Servicer shall cause such hazard
policies to be maintained or shall obtain a blanket policy insuring against
losses on the Mortgage Loans. The ability of the Master Servicer or Servicer to
ensure that hazard insurance proceeds are appropriately applied may be dependent
on its being named as an additional insured under any hazard insurance policy
and under any flood insurance policy referred to below, or upon the extent to
which information in this regard is furnished to the Master Servicer or the
Servicer by Mortgagors.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements on the property by fire,
lightning, explosion, smoke, windstorm, hail, riot, strike and civil commotion,
subject to the conditions and exclusions specified in each policy. The policies
relating to the Mortgage Loans will be underwritten by different insurers under
different state laws in accordance with different applicable state forms and
therefore will not contain identical terms and conditions, the basic terms
thereof are dictated by respective state laws. Such policies typically do not
cover any physical damage resulting from the following: war, revolution,
governmental actions, floods and other water-related causes, earth movement
(including earthquakes, landslides and mudflows), nuclear reactions, wet or dry
rot, vermin, rodents, insects or domestic animals, theft and, in certain cases,
vandalism. The foregoing list is merely indicative of certain kinds of uninsured
risks and is not intended to be all-inclusive. Where the improvements securing a
Mortgage Loan are located in a federally designated flood area at the time of
origination of such Mortgage Loan, the Pooling and Servicing Agreement or
Servicing Agreement generally requires the Master Servicer or Servicer to cause
to be maintained for each such Mortgage Loan serviced, flood insurance as
described under 'Servicing of Loans -- Maintenance of Insurance Policies and
Other Servicing Procedures.'
 
     Standard Hazard Insurance Policies for Manufactured Home Loans. The terms
of the Pooling and Servicing Agreement or Servicing Agreement will require the
Servicer or the Master Servicer, as applicable, to cause to be maintained with
respect to each Manufactured Home Loan one or more standard hazard insurance
policies which provide, at a minimum, the same coverage as a standard form fire
and extended coverage insurance policy that is customary for manufactured
housing, issued by a company authorized to issue such policies in the state in
which the Manufactured Home is located, and in an amount which is not less than
the maximum insurable value of such Manufactured Home or the principal balance
due from the Mortgagor on the related Manufactured Home Loan, whichever is less.
Such coverage may be provided by one or more blanket insurance policies covering
losses on the Manufactured Home Loans resulting from the absence or
insufficiency of individual standard hazard insurance policies. If a
Manufactured Home's location was, at the time of origination of the related
Manufactured Home Loan, within a federally designated flood area, the Servicer
or the Master Servicer also will be required to maintain flood insurance.
 
     If the Servicer or the Master Servicer repossesses a Manufactured Home on
behalf of the Trustee, the Servicer or the Master Servicer will either (i)
maintain at its expense hazard insurance with respect to such Manufactured Home
or (ii) indemnify the Trustee against any damage to such Manufactured Home prior
to resale or other disposition.
 
     Special Hazard Insurance Policy. Although the terms of such policies vary
to some degree, a special hazard insurance policy typically provides that, where
there has been damage to property securing a defaulted or foreclosed Loan (title
to which has been acquired by the insured) and to the extent such damage is not
covered by the standard hazard insurance policy or any flood insurance policy,
if applicable, required to be maintained with respect to such property, or in
connection with partial loss resulting from the application of the coinsurance
clause in a standard hazard insurance policy, the special hazard insurer will
pay the lesser of (i) the cost of repair or replacement of such property or
(ii) upon transfer of the property to the special hazard insurer, the unpaid
 
                                       51
 

<PAGE>

<PAGE>
principal balance of such Loan at the time of acquisition of such property by
foreclosure or deed in lieu of foreclosure, plus accrued interest to the date of
claim settlement and certain expenses incurred by the Master Servicer or the
Servicer with respect to such property. If the unpaid principal balance plus
accrued interest and certain expenses is paid by the special hazard insurer, the
amount of further coverage under the special hazard insurance policy will be
reduced by such amount less any net proceeds from the sale of the property. Any
amount paid as the cost of repair of the property will reduce coverage by such
amount. Special hazard insurance policies typically do not cover losses
occasioned by war, civil insurrection, certain governmental actions, errors in
design, faulty workmanship or materials (except under certain circumstances),
nuclear reaction, flood (if the mortgaged property is in a federally designated
flood area), chemical contamination and certain other risks.
 
     Restoration of the property with the proceeds described under (i) above is
expected to satisfy the condition under the pool insurance policy that the
property be restored before a claim under such pool insurance policy may be
validly presented with respect to the defaulted Loan secured by such property.
The payment described under (ii) above will render unnecessary presentation of a
claim in respect of such Loan under the pool insurance policy. Therefore, so
long as the pool insurance policy remains in effect, the payment by the special
hazard insurer of the cost of repair or of the unpaid principal balance of the
related Loan plus accrued interest and certain expenses will not affect the
total insurance proceeds paid to holders of the Securities, but will affect the
relative amounts of coverage remaining under the special hazard insurance policy
and pool insurance policy.
 
     Other Hazard-Related Insurance; Liability Insurance. With respect to Loans
secured by Multifamily Property, certain additional insurance policies may be
required with respect to the Multifamily Property; for example, general
liability insurance for bodily injury and property damage, steam boiler coverage
where a steam boiler or other pressure vessel is in operation, and rent loss
insurance to cover operating income losses following damage or destruction of
the Mortgaged Property. With respect to a Series for which Loans secured by
Multifamily Property are included in the Trust Fund, the related Prospectus
Supplement will specify the required types and amounts of additional insurance
and describe the general terms of such insurance and conditions to payment
thereunder.
 
BANKRUPTCY BOND
 
     In the event of a bankruptcy of a borrower, the bankruptcy court may
establish the value of the property securing the related Loan (and, if specified
in the related Prospectus Supplement, any related Additional Collateral) at an
amount less than the then outstanding principal balance of such Loan. The amount
of the secured debt could be reduced to such value, and the holder of such Loan
thus would become an unsecured creditor to the extent the outstanding principal
balance of such Loan exceeds the value so assigned to the property (and any
related Additional Collateral) by the bankruptcy court. In addition, certain
other modifications of the terms of a Loan can result from a bankruptcy
proceeding. See 'Certain Legal Aspects of Loans' herein. If so provided in the
related Prospectus Supplement, the Master Servicer will obtain a bankruptcy bond
or similar insurance contract (the 'bankruptcy bond') for proceedings with
respect to borrowers under the Bankruptcy Code. The bankruptcy bond will cover
certain losses resulting from a reduction by a bankruptcy court of scheduled
payments of principal of and interest on a Loan or a reduction by such court of
the principal amount of a Loan and will cover certain unpaid interest on the
amount of such a principal reduction from the date of the filing of a bankruptcy
petition.
 
     The bankruptcy bond will provide coverage in the aggregate amount specified
in the related Prospectus Supplement for all Loans in the Trust Fund secured by
single unit primary residences. Such amount will be reduced by payments made
under such bankruptcy bond in respect of such Loans, unless otherwise specified
in the related Prospectus Supplement, and will not be restored.
 
REPURCHASE BOND
 
     If so specified in the related Prospectus Supplement, the Seller, the
Depositor or the Master Servicer will be obligated to repurchase any Loan (up to
an aggregate dollar amount specified in the related Prospectus Supplement) for
which insurance coverage is denied due to dishonesty, misrepresentation or fraud
in connection with the origination or sale of such Loan. Such obligation may be
secured by a surety bond guaranteeing payment of the amount to be paid by the
Seller, the Depositor or the Master Servicer.

                                 THE AGREEMENTS
 
     The following summaries describe certain provisions of the Agreements. The
summaries do not purport to be complete and are subject to, and qualified in
their entirety by reference to, the provisions of the related Agreements. Where
particular provisions or terms used in the related Agreements are referred to,
such provisions or terms are as specified in the related Agreements.
 
ASSIGNMENT OF MORTGAGE ASSETS
 
     General. The Depositor will transfer, convey and assign to the Trustee all
right, title and interest of the Depositor in the Mortgage Assets and other
property to be included in the Trust Fund for a Series. Such assignment will
include all principal and interest due on or with respect to the Mortgage Assets
after the Cut-off Date specified in the related Prospectus Supplement (except
for any Retained Interests). The Trustee will, concurrently with such
assignment, execute and deliver the Securities.
 
     Assignment of Private Mortgage-Backed Securities. The Depositor will cause
Private Mortgage-Backed Securities to be registered in the name of the Trustee
(or its nominee or correspondent). The Trustee (or its agent or correspondent)
will have possession of any certificated Private Mortgage-Backed Securities.
Unless otherwise specified in the related Prospectus Supplement, the Trustee
will not be in possession of or be assignee of record of any underlying assets
for a Private Mortgage-Backed Security. See 'The Trust Funds -- Private
Mortgage-Backed Securities' herein. Each Private Mortgage-Backed Security will
be identified in a schedule appearing as an exhibit to the related Agreement
(the 'Mortgage Certificate Schedule'), which will specify the original principal
amount, outstanding principal balance as of the Cut-off Date, annual
pass-through rate or interest rate and maturity date for each Private
Mortgage-Backed Security conveyed to the Trustee. In the related Agreement, the
Depositor will represent and warrant to the Trustee regarding the Private
Mortgage-Backed Securities: (i) that the information contained in the Mortgage
Certificate Schedule is true and correct in all material respects; (ii) that,
immediately prior to the conveyance of the Private Mortgage-Backed Securities,
the Depositor had good title thereto, and was the sole owner thereof (subject to
any Retained Interests); (iii) that there has been no other sale by it of such
Private Mortgage-Backed Securities and (iv) that there is no existing lien,
charge, security interest or other encumbrance (other than any Retained
Interest) on such Private Mortgage-Backed Securities.
 
     Assignment of Agency Securities. The Depositor will transfer, convey and
assign to the Trustee (or its nominee or correspondent) all right, title and
interest of the Depositor in the Agency Securities and other property to be
included in the Trust Fund for a Series. Such assignment will include all
principal and interest due on or with respect to the Agency Securities after the
Cut-off Date specified in the related Prospectus Supplement (except for any
Retained Interest). The Depositor will cause the Agency Securities to be
registered in the name of the Trustee (or its nominee or correspondent), and the
Trustee will concurrently authenticate and deliver the Securities. Each Agency
Security will be identified in a schedule appearing as an exhibit to the related
Agreement, which will specify as to each Agency Security the original principal
amount and outstanding principal balance as of the Cut-off Date and the annual
pass-through rate or interest rate for each Agency Security conveyed to the
Trustee.
 
     Assignment of Mortgage Loans. In addition, the Depositor will, as to each
Mortgage Loan, deliver or cause to be delivered to the Trustee, or, as specified
in the related Prospectus Supplement, the Custodian, the Mortgage Note endorsed
without recourse to the order of the Trustee or in blank, the original Mortgage
with evidence of recording indicated thereon (except for any Mortgage not
returned from the public recording office, in which case a copy of such Mortgage
will be delivered, together with a certificate that the original of such
mortgage was delivered to such recording office), an assignment of the Mortgage
in recordable form and, if applicable, any riders or modifications to such
Mortgage Note and Mortgage, together with certain other documents as set forth
in the related Agreement. The Trustee, or, if so specified in the related
Prospectus Supplement, the Custodian, will hold such documents in trust for the
benefit of the Securityholders.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Depositor will, at the time of delivery of the Securities, cause assignments to
the Trustee of the Mortgage Loans to be recorded in the appropriate public
office for real property records, except in states where, in the opinion of
counsel acceptable to the Trustee, such recording is not required to protect the
Trustee's interest in the Mortgage Loan. As promptly as possible, the Depositor
will cause such assignments to be so recorded, in which event, the related
Agreement
 
                                       53
 

<PAGE>

<PAGE>
may require the Depositor to repurchase from the Trustee any Mortgage Loan
required to be recorded but not recorded within such time, at the price
described above with respect to repurchase by reason of defective documentation.
Unless otherwise provided in the related Prospectus Supplement, the enforcement
of the repurchase obligation would constitute the sole remedy available to the
Securityholders or the Trustee for the failure of a Mortgage Loan to be
recorded.
 
     With respect to any Mortgage Loans which are Cooperative Loans, the
Depositor will cause to be delivered to the Trustee, its agent, or a custodian,
the related original cooperative note endorsed to the order of the Trustee, the
original security agreement, the proprietary lease or occupancy agreement, the
recognition agreement, an executed financing agreement and the relevant stock
certificate and related blank stock powers. The Depositor will file in the
appropriate office an assignment and a financing statement evidencing the
Trustee's security interest in each Cooperative Loan.
 
     Each Mortgage Loan will be identified in a schedule appearing as an exhibit
to the related Agreement (the 'Mortgage Loan Schedule'). Such Mortgage Loan
Schedule will specify, among other things, with respect to each Mortgage Loan:
the original principal amount and unpaid principal balance as of the Cut-off
Date; the current interest rate; the current Scheduled Payment of principal and
interest; the maturity date of the related mortgage note; if the Mortgage Loan
is an ARM, the Minimum Mortgage Rate, the Maximum Mortgage Rate, if any, and the
Periodic Rate Cap; and whether the Mortgage Loan is an Additional Collateral
Loan, a Balloon Loan, a Cooperative Loan, a GPM Loan, a GEM Loan, a Buy-Down
Loan or a Mortgage Loan with other than fixed Scheduled Payments and level
amortization.
 
     Assignment of Manufactured Home Loans. The Depositor will cause any
Manufactured Home Loans included in the Mortgage Assets for a Series of
Securities to be assigned to the Trustee, together with principal and interest
due on or with respect to the Manufactured Home Loans after the Cut-off Date
specified in the related Prospectus Supplement. Each Manufactured Home Loan will
be identified in a loan schedule (the 'Loan Schedule') appearing as an exhibit
to the related Agreement. Such Loan Schedule will specify, with respect to each
Manufactured Home Loan, among other things: the original principal balance and
the outstanding principal balance as of the close of business on the Cut-off
Date; the interest rate; the current Scheduled Payment of principal and
interest; and the maturity date of the Manufactured Home Loan.
 
     In addition, with respect to each Manufactured Home Loan, the Depositor
will deliver or cause to be delivered to the Trustee, or, as specified in the
related Prospectus Supplement, the custodian, the original Manufactured Home
Loan and copies of documents and instruments related to each Manufactured Home
Loan and the security interest in the Manufactured Home securing each
Manufactured Home Loan. To give notice of the right, title and interest of the
Securityholders to the Manufactured Home Loans, the Depositor will cause a UCC-1
financing statement to be filed identifying the Trustee as the secured party and
identifying all Manufactured Home Loans as collateral. Unless otherwise
specified in the related Prospectus Supplement, the Manufactured Home Loans will
not be stamped or otherwise marked to reflect their assignment from the
Depositor to the Trustee. Therefore, if a subsequent purchaser were able to take
physical possession of the Manufactured Home Loans without notice of such
assignment, the interest of the Securityholders in the Manufactured Home Loans
could be defeated. See 'Certain Legal Aspects of Loans -- Manufactured Home
Loans.'
 
     The Seller (or other party as described in the related Prospectus
Supplement) will provide limited representations and warranties to the Depositor
and the Trustee concerning the Manufactured Home Loans. Such representations and
warranties will include: (i) that the information contained in the Loan Schedule
provides an accurate listing of the Manufactured Home Loans and that the
information respecting such Manufactured Home Loans set forth in such Loan
Schedule is true and correct in all material respects at the date or dates
respecting which such information is furnished; (ii) that, immediately prior to
the conveyance of the Manufactured Home Loans, the Depositor had good title to,
and was sole owner of, each such Manufactured Home Loan (subject to any Retained
Interests); (iii) that there has been no other sale by it of such Manufactured
Home Loans and that the Manufactured Home Loan is not subject to any lien,
charge, security interest or other encumbrance; (iv) if the Master Servicer will
not directly service the Manufactured Home Loans, each Sub-Servicing Agreement
entered into with a Servicer with respect to Manufactured Home Loans comprising
the Mortgage Assets has been assigned and conveyed to the Trustee and is not
subject to any offset, counterclaim, encumbrance or other charge; and (v) the
Depositor has obtained from each of the Master Servicer, the Servicer, the
originator of the Manufactured Home Loans or such other entity that is the
seller of the related Manufactured Home Loan
 
                                       54

representations and warranties relating to certain information respecting the
origination of and current status of the Manufactured Home Loans, and has no
knowledge of any fact which would cause it to believe that such representations
and warranties are inaccurate in any material respect. See 'Loan Underwriting
Procedures and Standards' herein.
 
     Assignment of Participation Securities. The Depositor will cause any
Participation Securities obtained under a participation agreement to be assigned
to the Trustee by delivering to the Trustee the Participation Security, which
will be reregistered in the name of the Trustee. Unless otherwise specified in
the related Prospectus Supplement, the Trustee will not be in possession of or
be assignee of record with respect to the Loans represented by the Participation
Security. Each Participation Security will be identified in a 'Participation
Security Schedule' which will specify the original principal balance,
outstanding principal balance as of the Cut-off Date, pass-through rate and
maturity date for each Participation Security. In the related Agreement, the
Depositor will represent and warrant to the Trustee regarding the Participation
Security: (i) that the information contained in the Participation Security
Schedule is true and correct in all material respects; (ii) that, immediately
prior to the conveyance of the Participation Securities, the Depositor had good
title to and was sole owner of the Participation Security; (iii) that there has
been no other sale by it of such Participation Security and (iv) that such
Participation Security is not subject to any existing lien, charge, security
interest or other encumbrance (other than any Retained Interests).
 
REPURCHASE AND SUBSTITUTION OF LOANS
 
     Unless otherwise provided in the related Prospectus Supplement, if any
document in the Loan file delivered by the Depositor to the Trustee, or
Custodian on behalf of the Trustee, is found by the Trustee within 90 days of
the execution of the related Agreement (or promptly after the Trustee's receipt
of any document permitted to be delivered after the Closing Date) to be
defective in any material respect and the related Servicer or Seller does not
cure such defect within 60 days from the date the Master Servicer was notified
of the defect by the Trustee, or within such other period specified in the
related Prospectus Supplement, the related Servicer or Seller if, and to the
extent it is obligated to do so under the related servicing agreement or
mortgage loan sale agreement will, not later than 90 days or within such other
period specified in the related Prospectus Supplement, from the date the Seller
or the Master Servicer was notified of the defect by the Depositor, the Master
Servicer or the Trustee, repurchase the related Mortgage Loan or any property
acquired in respect thereof from the Trustee at a price equal to the outstanding
principal balance of such Mortgage Loan (or, in the case of a foreclosed
Mortgage Loan, the outstanding principal balance of such Mortgage Loan
immediately prior to foreclosure), plus accrued and unpaid interest to the date
of the next scheduled payment on such Mortgage Loan at the related Mortgage
Rate.
 
     Unless otherwise provided in the related Prospectus Supplement, the Master
Servicer may, rather than repurchase the Loan as described above, remove such
Loan from the Trust Fund (the 'Deleted Loan') and substitute in its place one or
more other Loans (each, a 'Qualified Substitute Mortgage Loan') provided,
however, that (i) with respect to a Trust Fund for which no REMIC election is
made, such substitution must be effected within 120 days of the date of initial
issuance of the Securities and (ii) with respect to a Trust Fund for which a
REMIC election or elections are made, the Trustee must have received a
satisfactory opinion of counsel that such substitution will not result in a
prohibited transactions tax under the Code or cause the Trust Fund to lose its
status as a REMIC, or in the case of a Trust Fund consisting of two or more
REMICs, that such substitution will not cause any such REMIC to lose its status
as a REMIC.
 
     Any Qualified Substitute Mortgage Loan will have, unless otherwise
specified in the related Prospectus Supplement, on the date of substitution,
(i) an outstanding principal balance, after deduction of all Scheduled Payments
due in the month of substitution, not in excess of the outstanding principal
balance of the Deleted Loan (the amount of any shortfall to be deposited to the
Certificate Account in the month of substitution for distribution to
Securityholders), (ii) an interest rate not lower than and not more than 1% of
the interest rate of the Deleted Loan, (iii) have a Loan-to-Value Ratio at the
time of substitution no higher than that of the Deleted Loan at the time of
substitution, (iv) have a remaining term to maturity not greater than (and not
more than one year less than) that of the Deleted Loan, and (v) comply with all
of the representations and warranties set forth in the related Agreement as of
the date of substitution. The related Agreement may include additional
requirements relating to ARMs or other specific types of Mortgage Loans, or
additional provisions relating to
 
                                       55
 

<PAGE>

<PAGE>
meeting the foregoing requirements on an aggregate basis where a number of
substitutions occur contemporaneously.
 
     Unless otherwise provided in the related Prospectus Supplement, the
above-described cure, repurchase or substitution obligations constitute the sole
remedies available to the Securityholders or the Trustee for a material defect
in a Loan document.
 
     Unless otherwise specified in the related Prospectus Supplement, the Seller
(or other party as described in the related Prospectus Supplement) will make
representations and warranties with respect to Loans which comprise the Mortgage
Assets for a Series. See 'Loan Underwriting Procedures and Standards --
Representations and Warranties' above. If the related Seller (or other party)
cannot cure a breach of any such representations and warranties in all material
respects within 60 days after notification by the Master Servicer, the Depositor
or the Trustee of such breach, and if such breach is of a nature that materially
and adversely affects interest of the Securityholders in such Loan, the Seller
is obligated to cure, substitute or repurchase the affected Mortgage Loan if
such Seller is required to do so under the applicable agreement.
 
REPORTS TO SECURITYHOLDERS
 
     The Master Servicer will prepare and will forward or will provide to the
Trustee for forwarding to each Securityholder on each Distribution Date, or as
soon thereafter as is practicable, a statement setting forth, to the extent

during such calendar year a report summarizing the items provided to
Securityholders as specified in the related Agreement to enable Securityholders
to prepare their tax returns including, without limitation, the amount of
original issue discount accrued on the Securities, if applicable. Information in
the Distribution Date and annual reports provided to the Securityholders will

However, the Master Servicer will provide to the Trustee a report by independent
public accountants with respect to the Master Servicer's servicing of the Loans.

     Unless provided in the related Prospectus Supplement, the reinvestment
income from the Subordination Reserve Fund, other Reserve Fund, Servicer

Trustee, the Master Servicer or a Servicer and not available for distributions
to Securityholders. See 'Servicing of Loans' herein.
 
EVENT OF DEFAULT AND RIGHTS UPON EVENTS OF DEFAULT
 
     Pooling and Servicing Agreement and Servicing Agreement. Events of Default
under the Pooling and Servicing Agreement or Servicing Agreement for each Series
of Certificates or Notes, respectively, generally include (i) any failure by the
Master Servicer to remit to the Trustee for distribution to the Securityholders
(or distribution to Holders of the Equity Certificates with respect to a Series
of Notes) of such Series any required payment which continues unremedied for the
number of days specified in the related Pooling and Servicing Agreement or
Servicing Agreement, after the giving of written notice of such failure,
requiring the same to be remedied, to the Master Servicer by the Trustee or the
Depositor with respect to each Series of Certificates or by the Trustee or the
Issuer with respect to each Series of Notes, or to the Master Servicer, the
Depositor and the Trustee with respect to each Series of Certificates or to the
Master Servicer, the Issuer and the Trustee with respect to each Series of Notes
by the related Holders of Securities of such Series evidencing at least 25% of
Voting Rights of the Securities for such Series, (ii) any failure by the Master
Servicer duly to observe or perform in any material respect any other of its
covenants or agreements in the related Pooling and Servicing Agreement or
Servicing Agreement which continues unremedied for 30 days after the giving of
written notice of such failure to the Master Servicer by the Trustee or the
Depositor with respect to each Series of Certificates or by the Trustee or the
Issuer with respect to each Series of Notes, or to the Master Servicer, the
Depositor and the Trustee with respect to each Series of Certificates or to the
Master Servicer, the Issuer and the Trustee with respect to each Series of Notes
by the Holders of Securities of such Series evidencing at least 25% of the
Voting Rights of the Securities and (iii) certain events in insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings and certain actions by the Master Servicer indicating its
insolvency, reorganization or inability to pay its obligations.
 
     Unless otherwise specified in the related Prospectus Supplement, so long as
an Event of Default remains unremedied under the Pooling and Servicing Agreement
or Servicing Agreement for a Series, the Trustee for such Series or Holders of
Securities of such Series evidencing at least 51% of the aggregate outstanding
principal amount of the Securities for such Series (the first 51% who provide
such notice) or the Depositor may terminate all of the rights and obligations of
the Master Servicer as servicer under the Pooling and Servicing Agreement or
Servicing Agreement and in and to the Mortgage Loans (other than its right as a
Securityholder (or as Holder of the Equity Certificates with respect to a Series
of Notes) under the Pooling and Servicing Agreement or Servicing Agreement, as
applicable, which rights the Master Servicer will retain under all
circumstances), whereupon the Trustee will succeed to all the responsibilities,
duties and liabilities of the Master Servicer under the Pooling and Servicing
Agreement or Servicing Agreement and will be entitled to reasonable servicing
compensation not to exceed the applicable servicing fee, together with other
servicing compensation in the form of assumption fees, late payment charges or
otherwise as provided in the related Pooling and Servicing Agreement or
Servicing Agreement. Unless otherwise specified in the related Prospectus
Supplement, in the event that the Trustee would be obligated to succeed the
Master Servicer but is unwilling so to act, it may appoint (or if it is unable
so to act, it shall appoint) or petition a court of competent jurisdiction for
the appointment of, a FNMA- or FHLMC-approved mortgage servicing institution
with a net worth of at least $10,000,000 or such other amount as specified in
the related Prospectus Supplement to act as a successor to the Master Servicer
under the related Pooling and Servicing Agreement or Servicing Agreement (unless
otherwise set forth in the related Pooling and Servicing Agreement or Servicing
Agreement). Pending such appointment, the Trustee is obligated to act in such
capacity.
 
     No Securityholder of a Series, solely by virtue of such Holder's status as
a Securityholder, will have any right under the Pooling and Servicing Agreement
or Servicing Agreement for such Series to institute any proceeding with respect
to the related Pooling and Servicing Agreement or Servicing Agreement, unless
such Holder previously has given to the Trustee for such Series written notice
of default and unless the Holders of Securities evidencing at least 25% of the
aggregate outstanding principal amount of the Securities for such Series have
made written request upon the Trustee to institute such proceeding in its own
name as Trustee

for 60 days has neglected or refused to institute any such proceeding.
 
     Indenture. Unless otherwise provided in the related Prospectus Supplement
for a Series of Notes, an Event of Default under the Indenture generally will
include: (i) a default for five days or more (or other period of time described
in the related Prospectus Supplement) in the payment of any principal of or
interest on any Note or Equity Certificates of such Series; (ii) failure to
perform any other covenant of the Issuer in the Indenture which continues for a
period of 30 days after notice thereof is given in accordance with the
procedures described in the related Prospectus Supplement; (iii) any
representation or warranty made by the Issuer in the Indenture or in any
certificate or other writing delivered pursuant thereto or in connection
therewith with respect to or affecting such Series having been incorrect in a
material respect as of the time made, and such breach is not cured within 30
days after notice thereof is given in accordance with the procedures described
in the related Prospectus Supplement; (iv) certain events of bankruptcy,
insolvency, receivership or liquidation of the Issuer; or (v) any other Event of
Default provided with respect to Notes of that Series.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, the Trustee or the holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may declare
the principal amount (or, if the Notes of that Series are Compound Interest
Securities, such portion of the principal amount as may be specified in the
terms of that Series, as provided in the related Prospectus Supplement) of all
the Notes of such Series to be due and payable immediately. Such declaration
may, under certain circumstances, be rescinded and annulled by the holders of a
majority in aggregate outstanding amount of the related Notes.
 
     If following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Trustee may,
in its discretion, notwithstanding such acceleration, elect to maintain
possession of the collateral securing the Notes of such Series and to continue
to apply payments on such collateral as if there had been no declaration of
acceleration if such collateral continues to provide sufficient funds for the
payment of principal of and interest on the Notes of such Series as they would
have become due if there had not been such a declaration. In addition, the
Trustee may not sell or otherwise liquidate the collateral securing the Notes of
a Series following an Event of Default, unless (a) the holders of 100% of the
then aggregate outstanding amount of the Notes of such Series consent to such
sale, (b) the proceeds of such sale or liquidation are sufficient to pay in full
the principal of and accrued interest, due and unpaid, on the outstanding Notes
of such Series at the date of such sale or (c) the Trustee determines that such
collateral would not be sufficient on an ongoing basis to make all payments on
such Notes as such payments would have become due if such Notes had not been
declared due and payable, and the Trustee obtains the consent of the holders of
66 2/3% of the then aggregate outstanding amount of the Notes of such Series.
 
     In the event that the Trustee liquidates the collateral in connection with
an Event of Default, the Indenture provides that the Trustee will have a prior
lien on the proceeds of any such liquidation for unpaid fees and expenses. As a
result, upon the occurrence of such an Event of Default, the amount available
for payments to the Noteholders would be less than would otherwise be the case.
However, the Trustee may not institute a proceeding for the enforcement of its
lien except in connection with a proceeding for the enforcement of the lien of
the Indenture for the benefit of the Noteholders after the occurrence of such an
Event of Default.
 
     In the event the principal of the Notes of a Series is declared due and
payable, as described above, the holders of any such Notes issued at a discount
from par may be entitled to receive no more than an amount equal to the unpaid
principal amount thereof less the amount of such discount that is unamortized.
 
     No Noteholder or Holder of an Equity Certificate of a Series, solely by
virtue of such Holder's status as a Noteholder or Holder of an Equity
Certificate, will have any right under an Owner Trust Agreement or Indenture for
such Series to institute any proceeding with respect to such Agreement unless
such holder previously has given to the Trustee for such Series written notice
of default and unless the Holders of Notes or Equity Certificates of any class
evidencing at least 25% of the aggregate Percentage Interests constituting such
class have made written request upon the Trustee to institute such proceeding in
its own name as Trustee thereunder and have offered to the Trustee reasonable
indemnity, and the Trustee for 60 days has neglected or refused to institute any
such proceeding.
 
     Pursuant to the terms of the Indenture, if an Event of Default occurs and
is continuing, Senior Securityholders may be entitled to exercise certain rights
of the Holders of the Securities, without the consent of
 
                                       59

Subordinate Securityholders, and the Subordinate Securityholders may exercise
such rights only with the prior consent of the Senior Securityholders.
 
THE OWNER TRUSTEE
 
     The identity of the commercial bank, national banking association, banking
corporation, savings and loan association or trust company named as the Owner
Trustee for each Series of Notes will be set forth in the related Prospectus
Supplement. The entity serving as Owner Trustee may have normal banking
relationships with the Depositor or the Master Servicer.
 
THE TRUSTEE
 
     The identity of the commercial bank, national banking association, banking
corporation, savings and loan association or trust company named as the Trustee
for each Series of Securities will be set forth in the related Prospectus
Supplement. The entity serving as Trustee may have normal banking relationships
with the Depositor or the Master Servicer. In addition, for the purpose of
meeting the legal requirements of certain local jurisdictions, the Trustee will
have the power to appoint co-trustees or separate trustees of all or any part of
the Trust Fund relating to a Series of Securities. In the event of such
appointment, all rights, powers, duties and obligations conferred or imposed
upon the Trustee by the Pooling and Servicing Agreement or Indenture relating to
such Series will be conferred or imposed upon the Trustee and each such separate
trustee or co-trustee jointly, or, in any jurisdiction in which the Trustee
shall be incompetent or unqualified to perform certain acts, singly upon such
separate trustee or co-trustee who shall exercise and perform such rights,
powers, duties and obligations solely at the direction of the Trustee. The
Trustee may also appoint agents to perform any of the responsibilities of the
Trustee, which agents shall have any or all of the rights, powers, duties and
obligations of the Trustee conferred on them by such appointment; provided that
the Trustee shall continue to be responsible for its duties and obligations
under the related Agreement.
 
DUTIES OF THE TRUSTEE
 
     The Trustee makes no representations as to the validity or sufficiency of
any related Agreement, the Securities or of any Mortgage Asset or related
documents. If no Event of Default (as defined in the related Pooling and
Servicing Agreement, Sale and Servicing Agreement or Indenture) has occurred,
the Trustee is required to perform only those duties specifically required of it
under the related Agreement. Upon receipt of the various certificates,
statements, reports or other instruments required to be furnished to it, the
Trustee is required to examine them to determine whether they are in the form
required by the related Agreement. However, the Trustee will not be responsible
for the accuracy or content of any such documents furnished by it or the
Securityholders to the Master Servicer under the related Agreement.
 
     The Trustee may be held liable for its own grossly negligent action or
failure to act, or for its own willful misconduct; provided, however, that the
Trustee will not be personally liable with respect to any action taken, suffered
or omitted to be taken by it in good faith in accordance with the direction of
the Securityholders in an Event of Default. See 'Event of Default and Rights
Upon Events of Default' above. The Trustee is not required to expend or risk its
own funds or otherwise incur any financial liability in the performance of any
of its duties under the related Agreement, or in the exercise of any of its
rights or powers, if it has reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.
 
RESIGNATION OF TRUSTEE
 
     The Trustee may, upon written notice to the Depositor, the Master Servicer
and to all Securityholders; provided, that such resignation shall not be
effective until a successor trustee is appointed. If no successor Trustee has
been appointed and has accepted the appointment within 60 days after giving such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for appointment of a successor Trustee; provided, that such the
resigning Trustee shall not resign and be discharged until such time as the
successor trustee is approved by each Rating Agency. The Trustee may also be
removed at any time (i) by the Depositor, if the Trustee ceases to be eligible
to continue as such under the related Pooling and Servicing Agreement or
Indenture, (ii) if the Trustee becomes insolvent, (iii) if a tax is imposed or
threatened with respect
 
                                       60
 

<PAGE>

<PAGE>
to the Trust Fund by any state in which the Trustee or the Trust Fund held by
the Trustee pursuant to the related Agreement is located, or (iv) by the Holders
of Securities evidencing at least 51% of the aggregate outstanding principal
amount of the Securities in the Trust Fund upon notice to the Trustee and to the
Depositor. Any resignation or removal of the Trustee and appointment of a
successor Trustee will not become effective until acceptance of the appointment
by the successor Trustee.
 
CERTIFICATE ACCOUNT
 
     The Trustee will establish a separate account (the 'Certificate Account')
in its name as Trustee for the Securityholders, or if it is so specified in the
related Prospectus Supplement, the Certificate Account may be established by the
Master Servicer in the name of the Trustee. Unless otherwise specified in the
related Prospectus Supplement, the Certificate Account will be an Eligible
Account, and the funds held therein may be invested, pending disbursement to
Securityholders of the related Series, pursuant to the terms of the related
Pooling and Servicing Agreement or the related Servicing Agreement and
Indenture, in Eligible Investments. Unless otherwise specified in the related
Prospectus Supplement, the Master Servicer or the Trustee will be entitled to
receive, as additional compensation, any interest or other income earned on
funds in the Certificate Account. There will be deposited into the Certificate
Account monthly all funds received from the Master Servicer and required
withdrawals from any reserve funds. Unless otherwise specified in the related
Prospectus Supplement, the Trustee is permitted from time to time to make
withdrawals from the Certificate Account for each Series to remove amounts
deposited therein in error, to pay to itself or the Master Servicer any
reinvestment income on funds held in the Certificate Account to the extent it is
entitled, to remit to the Master Servicer its Servicing Fee, assumption or
substitution fees, late payment charges and other mortgagor charges,
reimbursement of Advances and expenses, to make deposits to any reserve fund, to
make regular distributions to the Securityholders, to clear and terminate the
Certificate Account and to make other withdrawals as required or permitted by
the related Agreements.
 
EXPENSE RESERVE FUND
 
     If specified in the Prospectus Supplement relating to a Series, the
Depositor may deposit on the related Closing Date in an account to be
established with the Trustee (the 'Expense Reserve Fund') cash or Eligible
Investments which will be available to pay anticipated fees and expenses of the
Trustee or other agents. The Expense Reserve Fund for a Series may also be
funded over time through the deposit therein of all or a portion of cash flow,
to the extent described in the related Prospectus Supplement. The Expense
Reserve Fund, if any, will not be part of the Trust Fund held for the benefit of
the Holders. Amounts on deposit in any Expense Reserve Fund will be invested in
one or more Eligible Investments.
 
AMENDMENT OF AGREEMENTS
 
     Unless otherwise specified in the Prospectus Supplement, the Pooling and
Servicing Agreement for each Series of Certificates may be amended by the
Depositor, the Master Servicer, and the Trustee with respect to such Series,
without notice to or consent of the Certificateholders (i) to cure any
ambiguity, (ii) to correct or supplement any provision therein which may be
defective or inconsistent with any other provision therein, (iii) to make any
other provisions with respect to matters or questions arising under such Pooling
and Servicing Agreement which are not inconsistent with any other provisions of
such Pooling and Servicing Agreement or (iv) to comply with any requirements
imposed by the Code; provided that such amendment (other than pursuant to clause
(iv) above) will not adversely affect in any material respect the interests of
any Certificateholders of such Series.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Pooling and Servicing Agreement for each Series of Certificates may also be
amended by the Trustee, the Master Servicer and the Depositor with respect to
such Series with the consent of the Holders possessing not less than 66 2/3% of
the aggregate outstanding principal amount of the Certificates of each Class of
such Series affected thereby, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of such Pooling and
Servicing Agreement or modifying in any manner the rights of Certificateholders
of such Series; provided, however, that no such amendment may (i) reduce the
amount or delay the timing of payments on any Certificate without the consent of
the Holder of such Certificate; (ii) adversely affect the REMIC status, if a
REMIC
 
                                       61
 

<PAGE>

<PAGE>
election or elections have been made, for the related Trust Fund of a Series; or
(iii) reduce the aforesaid percentage of aggregate outstanding principal amount
of Certificates of each Class, the Holders of which are required to consent to
any such amendment without the consent of the Holders of 100% of the aggregate
outstanding principal amount of each Class of Certificates affected thereby.
 
     Notwithstanding the foregoing, if a REMIC election or elections have been
made with respect to the related Trust Fund, the Trustee will not be entitled to
consent to any amendment to a Pooling and Servicing Agreement without having
first received an opinion of counsel to the effect that such amendment or the
exercise of any power granted to the Master Servicer, the Depositor or the
Trustee in accordance with such amendment will not result in the imposition of a
tax on the related Trust Fund or any related REMIC or cause such Trust Fund or
any such REMIC to fail to qualify as a REMIC.
 
     Unless otherwise specified in the Prospectus Supplement, the Servicing
Agreement or Indenture for each Series of Notes may be amended by the parties
thereto without the consent of any of the Noteholders covered by such Agreement
(i) to cure any ambiguity, (ii) to correct, modify or supplement any provision
therein which may be defective or inconsistent with any other provision therein
or (iii) to make any other provisions with respect to matters or questions
arising under the Agreement which are not inconsistent with the provisions
thereof, provided that such action will not adversely affect in any material
respect the interests of any Noteholder covered by the Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicing Agreement or Indenture for each Series of Notes may also be amended by
the parties thereto with the consent of the Holders evidencing not less than
66 2/3% of the aggregate outstanding principal amount of the Notes of each Class
of such Series affected thereby, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of such Agreement or
modifying in any manner the rights of Noteholders of such Series; provided,
however, that no such amendment may (i) reduce the amount of or delay the timing
of, payments received on any Note without the consent of the holder of such
Note, (ii) adversely affect in any material respect the interests of the holders
of any Class of Notes in a manner other than as described in (i), without the
consent of the holders of Notes of such Class evidencing not less than 66 2/3%
of the aggregate outstanding principal amount of the Notes of each Class of such
Series affected thereby or (iii) reduce the aforesaid percentage of aggregate
outstanding principal amount of Notes of each Class, the Holders of which are
required to consent to any such amendment without the consent of the Holders of
100% of the aggregate outstanding principal amount of each Class of Notes
affected thereby.
 
VOTING RIGHTS
 
     The related Prospectus Supplement will set forth the method of determining
allocation of voting rights with respect to a Series, if other than as set forth
herein. If specified in the related Prospectus Supplement, a provider of credit
enhancement may be entitled to certain Voting Rights of the Securityholders.
 
REMIC ADMINISTRATOR
 
     With respect to any Multiple Class Series of Certificates as to which a
REMIC election is made, preparation of certain reports and certain other
administrative duties with respect to the Trust Fund may be performed by a REMIC
administrator, who may be an affiliate of the Depositor.
 
TERMINATION
 
     The obligations created by the related Agreements for a Series will
terminate upon the distribution to Securityholders of all amounts distributable
to them pursuant to such Agreements after (i) the later of the final payment or
other liquidation of the last Mortgage Loan remaining in the Trust Fund for such
Series or the disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure in respect of any Mortgage Loan or (ii) the repurchase by
the Master Servicer or the Depositor (or other party as specified in the
Prospectus Supplement) from the Trustee for such Series of all Mortgage Loans at
that time subject to the related Agreements and all property acquired in respect
of any Mortgage Loan. The exercise of such right will effect early retirement of
the Securities of such Series, but such right to so purchase is subject to the
aggregate principal balances of the Mortgage Loans at the time of repurchase
being less than a fixed percentage, to be set forth in the related Prospectus
Supplement, of the Cut-off Date Aggregate Principal Balance. In no event,
 
                                       62
 

<PAGE>

<PAGE>
however, will the trust created by the related Agreements continue beyond the
expiration of 21 years from the death of the last survivor of certain persons
identified therein. For each Series, the Master Servicer or the Trustee, as
applicable, will give written notice of termination of the related Agreements to
each Securityholder, and the final distribution will be made only upon surrender
and cancellation of the Securities at an office or agency specified in the
notice of termination. See 'Description of the Securities -- Optional
Termination' herein.
 
                         CERTAIN LEGAL ASPECTS OF LOANS
 
     The following discussion contains summaries of certain legal aspects of
housing loans which are general in nature. Because such legal aspects are
governed 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
properties securing the housing loans are situated. The summaries are qualified
in their entirety by reference to the applicable federal and state laws
governing the Loans.
 
MORTGAGES
 
     The Mortgage Loans comprising or underlying the Mortgage Assets for a
Series will be secured by either mortgages or deeds of trust or deeds to secure
debt, depending upon the prevailing practice in the state in which the property
subject to a Mortgage Loan is located. The filing of a mortgage, deed of trust
or deed to secure debt creates a lien or title interest upon the real property
covered by such instrument and represents the security for the repayment of an
obligation that is customarily evidenced by a promissory note. It is not prior
to the lien for real estate taxes and assessments or other charges imposed under
governmental police powers. Priority with respect to such instruments depends on
their terms and in some cases the term of separate subordination or
intercreditor agreements, the knowledge of the parties to the mortgage and
generally on the order of recording with the applicable state, county or
municipal office. There are two parties to a mortgage, the mortgagor, who is the
borrower/homeowner or the land trustee (as described below), 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/homeowner is the beneficiary. At
origination of a mortgage loan, the borrower executes a separate undertaking to
make payments on the mortgage note. A deed of trust transaction normally has
three parties, the trustor, who is the borrower/homeowner, the beneficiary, who
is the lender, and the trustee, a third-party grantee. Under a deed of trust,
the trustor grants the property, irrevocably until the debt is paid, in trust,
generally with a power of sale, to the trustee to secure payment of the
obligation. A deed to secure debt typically has two parties, pursuant to which
the borrower, or grantor, conveys title to the real property to the grantee, or
lender a power of sale, until such times as the debt is repaid. The mortgagee's
authority under a mortgage or a deed to secure debt and the trustee's authority
under a deed of trust are governed by the law of the state in which the real
property is located, the express provisions of the mortgage, the deed to secure
debt, or deed of trust, and, in some cases, in deed of trust transactions, the
directions of the beneficiary.
 
COOPERATIVE LOANS
 
     If specified in the Prospectus Supplement relating to a Series of
Securities, the Mortgage Loans may also contain Cooperative Loans evidenced by
promissory notes secured by security interests in shares issued by private
corporations which are entitled to be treated as housing cooperatives under the
Code and in the related proprietary leases or occupancy agreements granting
exclusive rights to occupy specific dwelling units in the corporations'
buildings. The security agreement will create a lien upon, or grant a title
interest in, the cooperative shares and proprietary leases or occupancy
agreements, the priority of which will depend on the terms of the particular
security agreement as well as the order of recordation of the agreement or the
filing of the financing statements related thereto in the appropriate recording
office, or the taking of possession of the cooperative shares; depending on the
law of the state where the cooperative is located. Such a lien or security
interest is not, in general, prior to liens in favor of the cooperative
corporation for unpaid assessments or common charges. Such a lien or security
interest is not prior to the lien for real estate taxes and assessments and
other charges imposed under governmental police powers.
 
     Unless otherwise specified in the related Prospectus Supplement, all
cooperative apartments relating to the Cooperative Loans are located in the
State of New York. A corporation which is entitled to be treated as a
 
                                       63
 

<PAGE>

<PAGE>
housing cooperative under the Code owns all the real property or some interest
therein sufficient to permit it to own 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 and hazard and liability
insurance. If there is a blanket mortgage or mortgages on the cooperative
apartment building and/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, is also responsible for meeting these mortgage or rental
obligations. The interest of the occupant under proprietary leases or occupancy
agreements as to which that Cooperative is the landlord are generally
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 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. A
foreclosure by the holder of a blanket mortgage could eliminate or significantly
diminish the value of any collateral held by the lender who financed an
individual tenant-stockholder of Cooperative shares or, in the case of the
Mortgage Loans, the collateral securing the Cooperative Loans. Similarly, the
termination of the land lease by its holder could eliminate or significantly
diminish the value of any collateral held by the lender who financed an
individual tenant-stockholder of the 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 which 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 a
security interest in the occupancy agreement or proprietary lease and in the
related Cooperative shares. The lender 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 'Realizing on Cooperative Loan Security' below.
 
     Tax Aspects of Cooperative Ownership. In general, a 'tenant-stockholder'
(as defined in Section 216(b)(2) of the Code) of a corporation that qualifies as
a 'cooperative housing corporation' within the meaning of Section 216(b)(1) of
the Code is allowed a deduction for amounts paid or accrued within his taxable
year to the corporation representing his proportionate share of certain interest
expenses and certain real estate taxes allowable as a deduction under Section
216(a) of the Code to the corporation under Sections 163 and 164 of the Code. In
order for a corporation to qualify under Section 216(b)(1) of the Code for its
taxable year in which such items are allowable as a deduction to the
corporation, such section requires, among other things, that at least 80% of the
gross income of the corporation be derived from its tenant-stockholders. By
virtue of this requirement, the status of a corporation for purposes of Section
216(b)(1) of the Code must be determined on a year-to-year basis. Consequently,
there can be no assurance that cooperatives relating to the Cooperative Loans
will qualify under such section for any particular year. In the event that such
a cooperative fails to qualify for one or more years, the value of the
collateral securing any related Cooperative Loans could be significantly
impaired because no deduction would be allowable to tenant-stockholders under
Section 216(a) of the Code with respect to those years. In view of the
significance of the tax benefits accorded tenant-stockholders of a corporation
that qualifies under Section 216(b)(1) of the Code, the likelihood that such a
failure would be permitted to continue over a period of years appears remote.

FORECLOSURE ON MORTGAGES
 
     Foreclosure of a deed of trust or a deed to secure debt is generally
accomplished by a non-judicial trustee's sale under a specific provision in the
deed of trust which authorizes the trustee to sell the property upon any default
by the borrower under the terms of the note or deed of trust. In some states,
the trustee must record a notice of default and send a copy to the
borrower-trustor and to any person who has recorded a request for a copy of a
notice of default and notice of sale. In addition, the trustee in some states
must provide notice to any other individual having an interest in the real
property, including any junior lienholders. The trustor, borrower, or any 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. Generally, state law controls
the amount of foreclosure expenses and costs, including attorney's fees, which
may be recovered by a lender. If the deed of trust is not reinstated, a notice
of sale must be posted in a public place and, in most states, published for a
specific period of time in one or more newspapers. In addition, some state laws
require that a copy of the notice of sale be posted on the property, recorded
and sent to all parties having an interest in the real property.
 
     An action to foreclose a mortgage is an action to recover the mortgage debt
by enforcing the mortgagee's rights under the mortgage. It is regulated by
statutes and rules and subject throughout to the court's equitable powers.
Generally, a mortgagor is bound by the terms of the mortgage note and the
mortgage as made and cannot be relieved from his default if the mortgagee has
exercised his rights in a commercially reasonable manner. However, since a
foreclosure action historically was equitable in nature, the court may exercise
equitable powers to relieve a mortgagor of a default and deny the mortgagee
foreclosure on proof that either the mortgagor's default was neither willful nor
in bad faith or the mortgagee's action established a waiver, fraud, bad faith,
or oppressive or unconscionable conduct such as to warrant a court of equity to
refuse affirmative relief to the mortgagee. Under certain circumstances a court
of equity may relieve the mortgagor from an entirely technical default where
such default was not willful.
 
     A foreclosure action is subject to most of the delays and expenses of other
lawsuits if defenses or counterclaims are interposed, sometimes requiring up to
several years to complete. Similarly, a suit against the debtor on the mortgage
note may take several years and, generally, is a remedy alternative to
foreclosure, the mortgagee being precluded from pursuing both at the same time.
 
     In case of foreclosure under either a mortgage, a deed of trust, or a deed
to secure debt, the sale by the referee or other designated officer or by the
trustee is a public sale. However, because of the difficulty potential third
party purchasers at the sale 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. It is common for the lender to purchase the
property from the trustee or referee for an amount which may be equal to the
principal amount of the mortgage or deed of trust plus accrued and unpaid
interest and the expenses of foreclosure, in which event the mortgagor's debt
will be extinguished or the lender may purchase for a lesser amount in order to
preserve its right against a borrower to seek a deficiency judgment in states
where such a judgment is available. Thereafter, the lender will assume the
burdens of ownership, including obtaining casualty insurance, paying taxes 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. Any loss may
be reduced by the receipt of any mortgage guaranty insurance proceeds.
 
     A junior mortgagee may not foreclose on the property securing a junior
mortgage unless it forecloses subject to the senior mortgages, in which case it
must either pay the entire amount due on the senior mortgages to the senior
mortgagees prior to or at the time of the foreclosure sale or undertake the
obligation to make payments on the senior mortgages in the event the mortgagor
is in default thereunder, in either event adding the amounts expended to the
balance due on be subrogated to the rights of the senior mortgagees. In
addition, in the event that the foreclosure of a junior mortgage triggers the
enforcement of a 'due-on-sale' clause in a senior mortgage, the junior mortgagee
may be required to pay the full amount of the senior mortgages to the senior
mortgagees. Accordingly, with respect to those Mortgage Loans which are junior
mortgage loans, if the lender purchases the property, the lender's title will be
subject to all senior liens and claims and certain governmental liens. The
proceeds received by the referee or trustee from the sale are applied first to
the costs, fees and expenses of sale and then in satisfaction of the
indebtedness secured by the mortgage or deed of trust under
 
                                       65

which the sale was conducted. Any remaining proceeds are generally payable to
the holders of junior mortgages or deeds of trust and other liens and claims in
order of their priority, whether or not the borrower is in default. Any
additional proceeds are generally payable to the mortgagor or trustor. The
payment of the proceeds to the holders of junior mortgages may occur in the
foreclosure action of the senior mortgagee or may require the institution of
separate legal proceeds.
 
     The proceeds received by the referee or trustee from the sale are applied

generally payable to the mortgagor or trustor. The payment of the proceeds to
the holders of junior mortgages may occur in the foreclosure action of the
senior mortgagee or may require the institution of separate legal proceedings.
 
     The purposes of a foreclosure action are to enable the mortgagee to realize
upon its security and to bar the mortgagor, and all persons who have an interest
in the property which is subordinate to the foreclosing mortgagee, from their
'equity of redemption.' The doctrine of equity of redemption provides that,
until the property covered by a mortgage has been sold in accordance with a
properly conducted foreclosure and foreclosure sale, those having an interest
which is subordinate to that of the foreclosing mortgagee have an equity of
redemption and may redeem the property by paying the entire debt with interest.
In addition, in some states, when a foreclosure action has been commenced, the
redeeming party must pay certain costs of such action. Those having an equity of
redemption must be made parties and duly summoned to the foreclosure action in
order for their equity of redemption to be barred.
 
REALIZING UPON COOPERATIVE LOAN SECURITY
 
     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
which 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 which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the Cooperative will recognize the
lender's lien against proceeds from a sale of the Cooperative apartment,
subject, however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement or which have become liens on the shares relating
to the proprietary lease or occupancy agreement. The total amount owed to the
Cooperative by the tenant-stockholder, which the lender generally cannot
restrict and does not monitor, could reduce the value of the collateral below
the outstanding principal balance of the Cooperative Loan and accrued and unpaid
interest thereon.
 
     Recognition agreements also generally provide that in the event the lender
succeeds to the tenant-shareholder's shares and proprietary lease or occupancy
agreement as the result of realizing upon its collateral for a Cooperative Loan,
the lender must obtain the approval or consent of the Cooperative as required by
the proprietary lease before transferring the Cooperative shares and assigning
the proprietary lease. Generally, the lender is not limited in any rights it may
have to dispossess the tenant-stockholder.
 
                                       66
 

<PAGE>

<PAGE>
     The terms of the Cooperative Loans do not require either the
tenant-stockholder or the Cooperative to obtain title insurance of any type.
Consequently, the existence of any prior liens or other imperfections of title
also may adversely affect the marketability of the cooperative dwelling unit in
the event of foreclosure.
 
     In New York, lenders generally have realized upon the pledged shares and
proprietary lease or occupancy agreement given to secure a Cooperative Loan by
public sale in accordance with the provisions of Article 9 of the New York
Uniform Commercial Code (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. 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 a deed to secure
debt or foreclosure of a mortgage, the trustor or mortgagor and foreclosed
junior lienors are given a statutory period in which to redeem the property from
the foreclosure sale. The right of redemption should be distinguished from the
equity of redemption, which is a nonstatutory right that must be exercised prior
to 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 right of redemption would defeat the title of any purchaser from
the lender subsequent to foreclosure or sale under a deed of trust or a deed to
secure debt. Consequently, the practical effect of a right of redemption is to
force the lender to retain the property and pay the expenses of ownership until
the redemption period has run. In some states, there is no right to redeem
property after a trustee's sale under a deed of trust.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS
 
     Certain states have imposed statutory prohibitions which limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage or a deed
to secure debt. In some states, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure or sale under a deed of trust. A deficiency judgment is a personal
judgment against the former borrower equal in most cases to the difference
between the net amount realized upon the public sale of the real property and
the amount due to the lender. Other statutes require the beneficiary or
mortgagee to exhaust the security afforded under a deed of trust, deed to secure
debt 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, other statutory provisions limit any deficiency judgment
against the former borrower following a judicial sale to the excess of the
outstanding debt over the fair market value of the property at the time of the
public sale. The purpose of these statutes is generally to prevent a beneficiary
or a mortgagee from obtaining a large deficiency judgment against the former
borrower as a result of low or no bids at the judicial sale. Certain state laws
also place a limitation on the mortgagee with respect to late payment charges.
 
                                       67
 

<PAGE>

<PAGE>
     With respect to mortgage loans secured by collateral in addition to the
related properties, realization upon the additional collateral may be governed
by the Uniform Commercial Code in effect under the law of the state applicable
thereto. Some courts have interpreted the Uniform Commercial Code to prohibit or
limit a deficiency award in certain circumstances, including those in which the
disposition of the collateral was not conducted in a commercially reasonable
manner. In some states, the Uniform Commercial Code does not apply to liens upon
additional collateral consisting of certain types of personal property
(including, for example, bank accounts and, to a certain extent, insurance
policies and annuities). Realization upon such additional collateral will be
governed by state laws applicable thereto rather than by the Uniform Commercial
Code, and the availability of deficiency awards under such state laws may be
limited. Whether realization upon any Additional Collateral is governed by the
Uniform Commercial Code or by other state laws, the ability of secured parties
to realize upon the additional collateral may be limited by statutory
prohibitions that limit remedies in respect of the related mortgage loans. Such
prohibitions may affect secured parties either independently or in conjunction
with statutory requirements that secured parties proceed against the related
mortgaged properties first or against both such mortgaged properties and the
additional collateral concurrently. Some state statutes require secured parties
to exhaust the security afforded by the mortgaged properties through foreclosure
before attempting to realize upon the related additional collateral (including
any third-party guarantees). Other state statutes require secured parties to
foreclose upon mortgaged properties and additional collateral concurrently. In
states where statutes limit the rights of secured parties to obtain deficiency
judgments against borrowers or guarantors following foreclosure upon the related
mortgaged properties and where secured parties either are required or elect to
proceed against such mortgaged properties before proceeding against the related
additional collateral, limitations upon the amounts of deficiency judgments may
reduce the amounts that may be realized by the secured parties upon the
disposition of such additional collateral. Further, in certain states where
secured parties may choose whether to proceed against the related mortgaged
properties or additional collateral first or against both concurrently, the
secured parties, following a proceeding against one, may be deemed to have
elected a remedy and may be precluded from exercising remedies with respect to
the other. Consequently, the practical effect of the election requirement, in
those states permitting such election, is that secured parties will usually
proceed against both concurrently or against the mortgaged properties first if
prohibited from proceeding against both by state law.
 
     For Cooperative Loans. Generally, lenders realize on cooperative shares and
the accompanying proprietary lease given to secure a Cooperative Loan under
Article 9 of the UCC. Some courts have interpreted section 9-504 of the UCC to
prohibit a deficiency award unless the creditor establishes that the sale of the
collateral (which, in the case of a Cooperative Loan, would be the shares of the
Cooperative and the related proprietary lease or occupancy agreement) was
conducted in a commercially reasonable manner.
 
     Federal Bankruptcy and Other Laws Affecting Creditors' Rights. In addition
to laws limiting or prohibiting deficiency judgments, numerous other statutory
provisions, including the federal bankruptcy laws, the Relief Act, and state
laws affording relief to debtors, may interfere with or affect the ability of
the secured lender to realize upon collateral and/or enforce a deficiency
judgment. For example, with respect to federal bankruptcy law, the filing of a
petition acts as a stay against the enforcement of remedies for collection of a
debt. Moreover, a court with federal bankruptcy jurisdiction may permit a debtor
through a Chapter 13 under the Bankruptcy Code rehabilitative plan to cure a
monetary default with respect to a loan on a debtor's residence by paying
arrearages within a reasonable time period and reinstating the original loan
payment schedule even though the lender accelerated the loan and the lender has
taken all steps to realize upon his security (provided no sale of the property
has yet occurred) prior to the filing of the debtor's Chapter 13 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 loan
default by permitting the obligor to pay arrearages over a number of years.
 
     Courts with federal bankruptcy jurisdiction have also indicated that the
terms of a loan secured by property of the debtor may be modified if the
borrower has filed a petition under Chapter 13. These courts have suggested that
such modifications may include reducing the amount of each monthly payment,
changing the rate of interest, altering the repayment schedule 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. Federal bankruptcy law and
limited case law indicate that the foregoing modifications could not be applied
to the terms of a loan secured by property that is the principal residence of
the debtor. In all cases, the secured creditor is entitled to the value of its
security plus post-petition interest, attorney's fees and costs to the extent
the value of the security exceeds the debt. Therefore, with respect to any
 
                                       68
 

<PAGE>

<PAGE>
Additional Collateral Loan secured by property of the debtor in addition to the
debtor's principal residence, courts with federal bankruptcy jurisdiction may
reduce the amount of each monthly payment, change the rate of interest, alter
the repayment schedule, forgive all or a portion of the debt, reduce the
lender's security interest to the value of the collateral and otherwise subject
such mortgage loan to the cramdown provisions of Chapter 13.
 
     In a Chapter 11 case under the Bankruptcy Code, the lender is precluded
from foreclosing without authorization from the bankruptcy court. The lender's
lien may be transferred to other collateral and/or be limited in amount to the
value of the lender's interest in the collateral as of the date of the
bankruptcy. The loan term may be extended, the interest rate may be adjusted to
market rates and the priority of the loan may be subordinated to bankruptcy
court-approved financing. The bankruptcy court can, in effect, invalidate
due-on-sale clauses through confirmed Chapter 11 plans of reorganization.
 
     The Bankruptcy Code provides priority to certain tax liens over the
lender's security. This may delay or interfere with the enforcement of rights in
respect of a defaulted Loan. In addition, substantive requirements are imposed
upon lenders in connection with the origination and the servicing of mortgage
loans by numerous federal and some state consumer protection laws. The laws
include 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 regulations. These federal laws impose specific
statutory liabilities upon lenders who originate loans and who fail to comply
with the provisions of the law. In some cases, this liability may affect
assignees of the loans. With respect to mortgage loans secured by collateral in
addition to the related mortgaged properties, such tax liens may in certain
circumstances provide priority over the lien on such additional collateral.
 
     Certain of the Mortgage Loans may be subject to special rules, disclosure
requirements and other provisions that were added to the federal
Truth-in-Lending Act by the Homeownership and Equity Protection Act of 1994
(such Mortgage Loans, 'High Cost Loans'), if such Mortgage Loans were originated
on or after October 1, 1995, are not mortgaged loans made to finance the
purchase of the mortgaged property and have interest rates or origination costs
in excess of certain prescribed levels. Purchasers or assignees of any High Cost
Loan could be liable for all claims and subject to all defenses arising under
such provisions that the borrower could assert against the originator thereof.
Remedies available to the borrower include monetary penalties, as well as
rescission rights if the appropriate disclosures were not given as required. See
'Loan Underwriting Procedures and Standards -- Representations and Warranties.'
 
     Soldiers' and Sailors' Civil Relief Act. Generally, under the terms of the
Soldiers' and Sailors' Civil Relief Act of 1940, as amended (the 'Relief Act'),
a borrower who enters military service after the origination of such borrower's
Mortgage Loan (including a borrower who is a member of the National Guard or is
in reserve status at the time of the origination of the Mortgage Loan and is
later called to active duty) may not be charged interest above an annual rate of
6% during the period of such borrower's active duty status, unless a court
orders otherwise upon application of the lender. It is possible that such
interest rate limitation could have an effect, for an indeterminate period of
time, on the ability of the Trust Fund to collect full amounts of interest on
certain of the Mortgage Loans. Unless otherwise provided in the applicable
Prospectus Supplement, any shortfall in interest collections resulting from the
application of the Relief Act could result in losses to the holders of the
Securities. In addition, the Relief Act imposes limitations which would impair
the ability of the Trust Fund to foreclose on an affected Mortgage Loan during
the borrower'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.
 
JUNIOR MORTGAGES
 
     Some of the Mortgage Loans may be secured by junior mortgages or deeds of
trust, which are junior to senior mortgages or deeds of trust which are not part
of the Trust Fund. The rights of the Securityholders as the holders of a junior
deed of trust or a junior mortgage are subordinate in lien priority and in
payment priority to those of the holder of the senior mortgage or deed of trust,
including the prior rights of the senior mortgagee or beneficiary to receive and
apply hazard insurance and condemnation proceeds and, upon default of the
mortgagor, to cause a foreclosure on the property. Upon completion of the
foreclosure proceedings by the holder of the senior mortgage or the sale
pursuant to the deed of trust, the junior mortgagee's or junior beneficiary's
lien will be extinguished unless the junior lienholder satisfies the defaulted
senior loan or asserts its subordinate interest in a property in foreclosure
proceedings. See ' -- Foreclosure on Mortgages' herein.
 
                                       69
 

<PAGE>

<PAGE>
     Furthermore, the terms of the junior mortgage or deed of trust are
subordinate to the terms of the senior mortgage or deed of trust. In the event
of a conflict between the terms of the senior mortgage or deed of trust and the
junior mortgage or deed of trust, the terms of the senior mortgage or deed of
trust will govern generally. Upon a failure of the mortgagor or trustor to
perform any of its obligations, the senior mortgagee or beneficiary, subject to
the terms of the senior mortgage or deed of trust, may have the right to perform
the obligation itself. Generally, all sums so expended by the mortgagee or
beneficiary become part of the indebtedness secured by the mortgage or deed of
trust. To the extent a senior mortgagee expends such sums, such sums will
generally have priority over all sums due under the junior mortgage.
 
DUE-ON-SALE CLAUSES IN MORTGAGE LOANS
 
     Unless the Prospectus Supplement indicates otherwise, the Loans generally
contain due-on-sale clauses. These clauses permit the lender to accelerate the
maturity of the loan if the borrower sells, transfers or conveys the property.
The enforceability of these clauses has been the subject of legislation or
litigation in many states, and in some cases the enforceability of these clauses
has been 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 prohibit 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, which may have an impact upon the average
life of the Mortgage Loans and the number of Mortgage Loans which may be
outstanding until maturity.
 
     Upon foreclosure, courts have imposed general equitable principles. These
equitable principles are generally designed to relieve the borrower from the
legal effect of its defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have 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.
 
ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES
 
     Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Late charges and prepayment fees are typically retained by
servicers as additional servicing compensation.

EQUITABLE LIMITATIONS ON REMEDIES
 
     In connection with lenders' attempts to realize upon their security, courts
have invoked general equitable principles. The equitable principles are
generally 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 a lender to realize upon his
security if the default under the security agreement is not monetary, such as
the borrower's failure to adequately maintain the property or the borrower's
execution of secondary financing 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 security agreements receive notices in addition to the
statutorily prescribed minimums. For the most part, these cases have upheld the
notice provisions as being reasonable or have found that, in cases involving the
sale by a trustee under a deed of trust or by a mortgagee under a mortgage
having a power of sale, there is insufficient state action to afford
constitutional protections to the borrower.
 
     The Mortgage Loans may include a debt-acceleration clause, which permits
the lender to accelerate the debt upon a monetary default of the borrower, after
the applicable cure period. The courts of all states will enforce clauses
providing for acceleration in the event of a material payment default. However,
courts of any state, exercising equity jurisdiction, may refuse to allow a
lender to foreclose a mortgage or deed of trust when an acceleration of the
indebtedness would be inequitable or unjust and the circumstances would render
the acceleration unconscionable.
 
     Most conventional single-family mortgage loans may be prepaid in full or in
part without penalty. The regulations of the Federal Home Loan Bank Board, as
succeeded by the OTS, prohibit the imposition of a prepayment penalty or
equivalent fee for or in connection with the acceleration of a loan by exercise
of a due-on-sale clause. A mortgagee to whom a prepayment in full has been
tendered may be compelled to give either a release of the mortgage or an
instrument assigning the existing mortgage. The absence of a restraint on
prepayment, particularly with respect to Mortgage Loans having higher mortgage
rates, may increase the likelihood of refinancing or other early retirements of
the Mortgage Loans.
 
SUBORDINATE FINANCING
 
     When the mortgagor encumbers mortgaged property with one or more junior
liens, the senior lender is subjected to additional risk. First, the mortgagor
may have difficulty servicing and repaying multiple loans. In addition, if the
junior loan permits recourse to the mortgagor (as junior loans often do) and the
senior loan does not, a mortgagor may be more likely to repay sums due on the
junior loan than those on the senior loan. Second, acts of the senior lender
that prejudice the junior lender or impair the junior lender's security may
create a superior equity in favor of the junior lender. For example, if the
mortgagor and the senior lender agree to an increase in the principal amount of
or the interest rate payable on the senior loan, the senior lender may lose its
priority to the extent an existing junior lender is harmed or the mortgagor is
additionally burdened. Third, if the mortgagor defaults on the senior loan
and/or any junior loan or loans, the existence of junior loans and actions taken
by junior lenders can impair the security available to the senior lender and can
interfere with or delay the taking of action by the senior lender. Moreover, the
bankruptcy of a junior lender may operate to stay foreclosure or similar
proceeds by the senior lender.
 
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. Similar federal statutes
were in effect with respect to mortgage loans made during the first three months
of 1980. The OTS, as successor to the Federal Home Loan Bank Board, is
authorized to issue rules and regulations and to publish interpretations
governing implementation of Title V. Title V authorizes any state to reimpose
interest rate limits by adopting, before April 1, 1983, a state law, or by
certifying that the voters of such state have voted in favor of any provision,
 
                                       71
 

<PAGE>

<PAGE>
constitutional or otherwise, which expressly rejects an application of the
federal law. Fifteen states adopted such a law prior to the April 1, 1983
deadline. 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.
 
     In any state in which application of Title V has been expressly rejected or
a provision limiting discount points or other charges is adopted, no Mortgage
Loans originated after the date of such state action will be eligible as
Mortgage Assets if such Mortgage Loans bear interest or provide for discount
points or charges in excess of permitted levels. No Mortgage Loan originated
prior to January 1, 1980 will bear interest or provide for discount points or
charges in excess of permitted levels.
 
ADJUSTABLE INTEREST RATE LOANS
 
     ARMs originated by non-federally chartered lenders have historically been
subject 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 complied 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'
(including ARMs) 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; and
state-chartered savings banks and mortgage banking companies may originate
alternative mortgage instruments in accordance with the regulations promulgated
by the Federal Home Loan Bank Board, as succeeded by the OTS, 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.
 
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 will generally 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 addition, under federal environmental
legislation and possibly 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 otherwise is 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
secured lender.
 
MANUFACTURED HOME LOANS
 
     Security Interests in the Manufactured Homes. Law governing perfection of a
security interest in a Manufactured Home varies from state to state. Security
interests in Manufactured Homes may be perfected either by notation of the
secured party's lien on the certificate of title or by delivery of the required
documents and payment of a fee to the state motor vehicle authority, depending
on state law. In some nontitle states, perfection pursuant to the provisions of
the UCC is required. The lender or a servicer may effect such notation or
delivery of the required documents and fees, and obtain possession of the
certificate of title, as appropriate under the laws of the state in which any
manufactured home securing a Manufactured Home Loan is registered. In the event
such notation or delivery is not effected or the security interest is not filed
in accordance with the applicable law (for example, is filed under a motor
vehicle title statute rather than under the UCC, in a few states), a first
priority security interest in the Manufactured Home securing a Manufactured Home
Loan may not be obtained.
 
     As Manufactured Homes have become larger and often have been attached to
their sites without any apparent intention to move them, courts in many states
have held that Manufactured Homes, under certain
 
                                       72

circumstances, may become subject to real estate title and recording laws. As a
result, a security interest in a Manufactured Home could be rendered subordinate
to the interests of other parties claiming an interest in the Manufactured Home
under applicable state real estate law. In order to perfect a security interest
in a Manufactured Home under real estate laws, the holder of the security
interest must file either a 'fixture filing' under the provisions or the UCC or
a real estate mortgage under the real estate laws of the state where the home is
located. These filings must be made in the real estate records office of the
county where the home is located. Manufactured Home Loans typically contain
provisions prohibiting the borrower from permanently attaching the Manufactured
Home to its site. So long as the borrower does not violate this agreement, a
security interest in the Manufactured Home will be governed by the certificate
of title laws or the UCC, and the notation of the security interest on the
certificate of title or the filing of a UCC financing statement will be
effective to maintain the priority of the security interest in the Manufactured
Home. If, however, a Manufactured Home is permanently attached to its site,
other parties could obtain an interest in the manufactured home which is prior
to the security interest originally retained by the lender or its assignee.
 
     With respect to a Series of Securities evidencing interests in a Trust Fund
that includes Manufactured Home Loans and as described in the related Prospectus
Supplement, the Master Servicer may be required to perfect a security interest
in the Manufactured Home under applicable real estate laws. If such real estate
filings are not made and if any of the foregoing events were to occur, the only
recourse of the Securityholders would be against the Seller pursuant to its
repurchase obligation for breach of warranties. A PMBS Agreement pursuant to
which Private Mortgage-Backed Securities backed by Manufactured Home Loans are
issued will, unless otherwise specified in the related Prospectus Supplement,
have substantially similar requirements for perfection of a security interest.
 
     In general, upon an assignment of a Manufactured Home Loan, the certificate
of title relating to the Manufactured Home will not be amended to identify the
assignee as the new secured party. In most states, an assignment is an effective
conveyance of such security interest without amendment of any lien noted on the
related certificate of title and the new secured party succeeds to the
assignor's rights as the secured party. However, in some states there exists a
risk that, in the absence of an amendment to the certificate of title, such
assignment of the security interest might not be held effective against
creditors of the assignor.
 
     Relocation of a Manufactured Home. In the event that the owner of a
Manufactured Home moves the home to a state other than the state in which such
Manufactured Home initially is registered, under the laws of most states the
perfected security interest in the Manufactured Home would continue for four
months after such relocation and thereafter only if and after the owner
reregisters the Manufactured Home in such state. If the owner were to relocate a
Manufactured Home to another state and not reregister the Manufactured Home in
such state, and if steps are not taken to reperfect the Trustee's security
interest in such state, the security interest in the Manufactured Home would
cease to be perfected. A majority of states generally require surrender of a
certificate of title to reregister a Manufactured Home; accordingly, possession
of the certificate of title to such Manufactured Home must be surrendered or, in
the case of Manufactured Homes registered in states which provide for notation
of lien, the notice of surrender must be given to any person whose security
interest in the Manufactured Home is noted on the certificate of title.
Accordingly, the owner of the Manufactured Home Loan would have the opportunity
to reperfect its security interest in the Manufactured Home in the state of
relocation. In states which do not require a certificate of title for a
registration of a Manufactured Home, reregistration could defeat perfection. In
the ordinary course of servicing the Manufactured Home Loans, the Master
Servicer will be required to take steps to effect reperfection upon receipt of
notice of reregistration or information from the borrower as to relocation.
Similarly, when a borrower under a Manufactured Home Loan sells the related
Manufactured Home, the Trustee must surrender possession of the certificate of
title or the Trustee will receive notice as a result of its lien noted thereon
and accordingly will be an opportunity to require satisfaction of the related
Manufactured Home Loan before release of the lien. Under the related Pooling and
Servicing Agreement or Servicing Agreement, the Master Servicer is obligated to
take such steps, at the Master Servicer's expense, as are necessary to maintain
perfection of security interests in the Manufactured Homes. PMBS Agreements
pursuant to which Private Mortgage-Backed Securities backed by Manufactured Home
Loans are issued will impose substantially similar requirements.
 
     Intervening Liens. Under the laws of most states, liens for repairs
performed on a Manufactured Home take priority even over a perfected security
interest. The Master Servicer or the originator of such Loans will represent
that it has no knowledge of any such liens with respect to any Manufactured Home
securing payment
 
                                       73
 

<PAGE>

<PAGE>
on any Manufactured Home Loan. However, such liens could arise at any time
during the term of a Manufactured Home Loan. No notice will be given to the
Trustee or Securityholders in the event such a lien arises. PMBS Agreements
pursuant to which Private Mortgage-Backed Securities backed by Manufactured Home
Loans are issued will contain substantially similar requirements.
 
     Enforcement of Security Interests in Manufactured Homes. So long as the
Manufactured Home has not become subject to the real estate law, a creditor can
repossess a Manufactured Home securing a Manufactured Home Loan by voluntary
surrender, by 'self-help' repossession that is 'peaceful' (i.e., without breach
of the peace) or in the absence of voluntary surrender and the ability to
repossess without breach of the peace, by judicial process. The holder of a
Manufactured Home Loan must give the debtor a number of days notice, which
varies from 10 to 30 days depending on the state, prior to commencement of any
repossession. The UCC and consumer protection laws in most states place
restrictions on repossession sales, including requiring prior notice to the
debtor and commercial reasonableness in effecting such a sale. The law in most
states also requires that the debtor be given notice of any sale prior to resale
of the unit so that the debtor may redeem at or before such resale. In the event
of such repossession and resale of a Manufactured Home, the holder of a
Manufactured Home Loan would be entitled to be paid out of the sale proceeds
before such proceeds could be applied to the payment of the claims of unsecured
creditors or the holders or subsequently perfected interests or, thereafter, to
the borrower.
 
     Under the laws applicable in most states, a creditor is entitled to obtain
a deficiency judgment from a borrower for any deficiency on repossession and
resale of the Manufactured Home securing such borrower's loan. However, some
states impose prohibitions or limitations on deficiency judgments. See
'Anti-deficiency Legislation and Other Limitations on Lenders' above.
 
     Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws and general equitable principles, may limit or delay the
ability of a lender to repossess and resell collateral or enforce a deficiency
judgment. See 'Federal Bankruptcy and Other Laws Affecting Creditors' Rights'
and 'Equitable Limitations on Remedies' above.
 
     Consumer Protection Laws. The so-called 'Holder-In-Due-Course' rule of the
Federal Trade Commission is intended to defeat the ability of the transferor of
a consumer credit contract who is the seller of goods which gave rise to the
transaction (and certain related lenders and assignees) to transfer such
contract free of notice of claims by the borrower thereunder. The effect of this
rule is to subject the assignee of such a contract to all claims and defenses
which the borrower could assert against the seller of goods. Liability under
this rule is limited to amounts paid under a Manufactured Home Loan; however,
the borrower also may be able to assert the rule to set off remaining amounts
due as a defense against a claim brought against such borrower. Numerous other
federal and state consumer protection laws impose requirements applicable to the
origination and lending pursuant to the Manufactured Home Loan, including the
Truth-in-Lending Act, the Federal Trade Commission Act, the Fair Credit Billing
Act, the Fair Credit Reporting Act, the Equal Credit Opportunity Act, the Fair
Debt Collection Practices Act and the Uniform Consumer Credit Code. In the case
of some of these laws, the failure to comply with their provisions may affect
the enforceability of the related Manufactured Home Loan.
 
     Transfers of Manufactured Homes; Enforceability of 'Due-on-Sale' Clauses.
Loans and installment sale contracts relating to a Manufactured Home Loan
typically prohibit the sale or transfer of the related Manufactured Homes
without the consent of the lender and permit the acceleration of the maturity of
the Manufactured Home Loans by the lender upon any such sale or transfer for
which no such consent is granted.
 
     In the case of a transfer of a Manufactured Home, the lender's ability to
accelerate the maturity of the related Manufactured Home Loan will depend on the
enforceability under state law of the 'due-on-sale' clause. The Garn-St Germain
Depository Institutions Act of 1982 preempts, subject to certain exceptions and
conditions, state laws prohibiting enforcement of 'due-on-sale' clauses
applicable to the Manufactured Homes. See 'Due-on-Sale Clauses in Mortgage
Loans' above. With respect to any Manufactured Home Loan secured by a
Manufactured Home occupied by the borrower, the ability to accelerate will not
apply to those types of transfers discussed in 'Due-on-Sale Clauses in Mortgage
Loans' above. FHA Loans and VA Loans are not permitted to contain 'due-on-sale'
clauses, and so are freely assumable.
 
     Applicability of Usury Laws. Title V provides that, subject to the
following conditions, state usury limitations shall not apply to any loan which
is secured by a first lien on certain kinds of Manufactured Homes. The
Manufactured Home Loans would be covered if they satisfy certain conditions,
among other things,
 
                                       74

<PAGE>
governing the terms of any prepayments, late charges and deferral fees and
requiring a 30-day notice period prior to instituting any action leading to
repossession of or foreclosure with respect to the related unit. See
'Applicability of Usury Laws' above.
 
     Louisiana Law. Any contract secured by a manufactured home located in
Louisiana will be governed by Louisiana law rather than Article 9 of the UCC.
Louisiana laws provide similar mechanisms for perfection and enforcement of
security interests in manufactured housing used as collateral for an installment
sale contract or installment loan agreement.
 
     Under Louisiana law, a manufactured home that has been permanently affixed
to real estate will nevertheless remain subject to the motor vehicle
registration laws unless the obligor and any holder of a security interest in
the property execute and file in the real estate records for the parish in which
the property is located a document converting the unit into real property. A
manufactured home that is converted into real property but is then removed from
its site can be converted back to personal property governed by the motor
vehicle registration laws if the obligor executes and files various documents in
the appropriate real estate records and all mortgagees under real estate
mortgages on the property and the land to which it was affixed file releases
with the motor vehicle commission.
 
     So long as a manufactured home remains subject to the Louisiana motor
vehicle laws, liens are recorded on the certificate of title by the motor
vehicle commissioner and repossession can be accomplished by voluntary consent
of the obligor, executory process (repossession proceedings which must be
initiated through the courts but which involve minimal court supervision) or a
civil suit for possession. In connection with a voluntary surrender, the obligor
must be given a full release from liability for all amounts due under the
contract. In executory process repossessions, a sheriff's sale (without court
supervision) is permitted, unless the obligor brings suit to enjoin the sale,
and the lender is prohibited from seeking a deficiency judgment against the
obligor unless the lender obtained an appraisal of the manufactured home prior
to the sale and the property was sold for at least two-thirds of its appraised
value.
 
     Formaldehyde Litigation. A number of lawsuits are pending in the United
States alleging personal injury from exposure to the chemical formaldehyde,
which is present in many building materials, including such components of
manufactured housing as plywood flooring and wall paneling. Some of these
lawsuits are pending against manufacturers of manufactured housing, suppliers of
component parts, and related persons in the distribution process. The Depositor
is aware of a limited number of cases in which plaintiffs have won judgments in
these lawsuits.
 
     Under the FTC Rule, which is described above under 'Consumer Protection
Laws', the holder of any Loan secured by a Manufactured Home with respect to
which a formaldehyde claim has been successfully asserted may be liable to the
obligor for the amount paid by the obligor on the related Loan and may be unable
to collect amounts still due under the Loan. In the event an obligor is
successful in asserting such a claim, the related Securityholders could suffer a
loss if (i) the related Seller fails or cannot be required to repurchase the
affected Loan for a breach of representation and warranty and (ii) the Master
Servicer or the Trustee were unsuccessful in asserting any claim of contribution
or subrogation on behalf of the Securityholders against the manufacturer or
other persons who were directly liable to the plaintiff for the damages. Typical
products liability insurance policies held by manufacturers and component
suppliers of manufactured homes may not cover liabilities arising from
formaldehyde in manufactured housing, with the result that recoveries from such
manufacturers, suppliers or other persons may be limited to their corporate
assets without the benefit of insurance.
 
     Soldiers' and Sailors' Civil Relief Act. Generally, under the terms of the
Relief Act, a borrower who enters military service after the origination of such
borrower's Manufactured Home Loan (including a borrower who is a member of the
National Guard or is in reserve status at the time of the origination of the
Manufactured Home Loan and is later called to active duty) may not be charged
interest above an annual rate of 6% during the period of such borrower's active
duty status, unless a court orders otherwise upon application of the lender. It
is possible that such interest rate limitation could have an effect, for an
indeterminate period of time, on the ability of the Trust Fund to collect full
amounts of interest on certain of the Manufactured Home Loans. Unless otherwise
provided in the applicable Prospectus Supplement, any shortfall in interest
collections resulting from the application of the Relief Act could result in
losses to the holders of the Securities. In addition, the Relief Act imposes
limitations which would impair the ability of the Trust Fund to enforce the lien
with respect to an affected Manufactured Home Loan during the borrower's period
of active duty status. Thus, in the event that
 
                                       75
 

<PAGE>

<PAGE>
such a Manufactured Home Loan goes into default, there may be delays and losses
occasioned by the inability to enforce the lien with respect to the Manufactured
Home in a timely fashion.
 
     Forfeitures in Drug and RICO Proceedings. Federal law provides that
property owned by persons convicted of drug-related crimes or of criminal
violations of the Racketeer Influenced and Corrupt Organizations ('RICO')
statute can be seized by the government if the property was used in, or
purchased with the proceeds of, such crimes. Under procedures contained in the
Comprehensive Crime Control Act of 1984 (the 'Crime Control Act'), the
government may seize the property even before conviction. The government must
publish notice of the forfeiture proceeding and may give notice to all parties
'known to have an alleged interest in the property,' including the holders of
mortgage loans.
 
     A lender may avoid forfeiture of its interest in the property if it
establishes that: (i) its mortgage was executed and recorded before the
commission of the crime upon which the forfeiture is based, or (ii) the lender
was, at the time of the execution of the mortgage, 'reasonably without cause to
believe' that the property was used in, or purchased with the proceeds of,
illegal drug or RICO activities.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a general discussion of the anticipated material federal
income tax consequences of the purchase, ownership and disposition of the
Certificates and Notes offered hereunder where Thacher Proffitt & Wood, Brown &
Wood LLP or Stroock & Stroock & Lavan LLP is identified in the applicable
Prospectus Supplement as counsel to the Depositor (hereinafter 'Counsel to the
Depositor'). This discussion is directed solely to Securityholders that hold the
Securities as capital assets within the meaning of Section 1221 of the Internal
Revenue Code of 1986 (the 'Code') and does not purport to discuss all federal
income tax consequences that may be applicable to particular categories of
investors, some of which (such as banks, insurance companies and foreign
investors) may be subject to special rules. Further, the authorities on which
this discussion, and the opinion referred to below, are based are subject to
change or differing interpretations, which could apply retroactively. Taxpayers
and preparers of tax returns (including those filed by any REMIC or other
issuer) should be aware that under applicable Treasury regulations a provider of
advice on specific issues of law is not considered an income tax return preparer
unless the advice (i) is given with respect to events that have occurred at the
time the advice is rendered and is not given with respect to the consequences of
contemplated actions and (ii) is directly relevant to the determination of an
entry on a tax return. Accordingly, taxpayers should consult their own tax
advisors and tax return preparers regarding the preparation of any item on a tax
return, even where the anticipated tax treatment has been discussed herein. In
addition to the federal income tax consequences described herein, potential
investors should consider the state and local tax consequences, if any, of the
purchase, ownership and disposition of the Securities. See 'State and Other Tax
Consequences.' Securityholders are advised to consult their own tax advisors
concerning the federal, state, local or other tax consequences to them of the
purchase, ownership and disposition of the Certificates offered hereunder.
 
     The following discussion addresses securities of two general types: (i)
certificates (the 'REMIC Certificates') representing interests in a Trust Fund,
or a portion thereof, that the Trustee will elect to have treated as a real
estate mortgage investment conduit ('REMIC') under Sections 860A through 860G
(the 'REMIC Provisions') of the Code andebtedness of the Issuer for federal
income tax purposes. The Prospectus Supplement for each Series of Securities
will indicate which of the foregoing treatments will apply to such Series and,
if a REMIC election (or elections) will be made with respect to a Series of
Certificates, will identify all 'regular interests' and 'residual interests' in
the REMIC.
 
REMICs
 
     As to each Series of Certificates, unless otherwise disclosed in the
related Prospectus Supplement, the Trustee will covenant to elect to have
treated the Trust Fund, or a portion thereof, as one or more REMICs. The
Prospectus Supplement for each Series of Certificates will identify all
Certificates representing 'regular interests' and the 'residual interest' in
each such REMIC. If a REMIC election or elections will not be made for a Trust
Fund, the federal income tax consequences of the purchase, ownership and
disposition of the related Certificates will be set forth in the related
Prospectus Supplement. For purposes of this tax discussion, references to a
'Certificateholder' or a 'holder' are to the beneficial owner of a Certificate.
 
     The following discussion is based in part upon the rules governing original
issue discount that are set forth in Sections 1271-1273 and 1275 of the Code and
in the Treasury regulations issued thereunder (the 'OID Regulations'), and in
part upon the REMIC Provisions and the Treasury regulations issued thereunder
(the 'REMIC Regulations'). The OID Regulations do not adequately address certain
issues relevant to, and in some instances provide that they are not applicable
to, securities such as the Certificates.
 
     Classification of REMICs
 
     Upon the issuance of each Series of REMIC Certificates, Counsel to the
Depositor will deliver its opinion generally to the effect that, assuming
compliance with all provisions of the related Pooling and Servicing Agreement,
the related Trust Fund (or each applicable portion thereof) will qualify as a
REMIC and the REMIC Certificates offered with respect thereto will be considered
to evidence ownership of 'regular interests' ('REMIC Regular Certificates') or
'residual interests' ('REMIC Residual Certificates') in that REMIC within the
meaning of the REMIC Provisions.
 
                                       77
 

<PAGE>

<PAGE>
     If an entity electing to be treated as a REMIC fails to comply with one or
more of the ongoing requirements of the Code for such status during any taxable
year, the Code provides that the entity will not be treated as a REMIC for such
year and thereafter. In that event, such entity may be taxable as a corporation
under Treasury regulations, and the related REMIC Certificates may not be
accorded the status or given the tax treatment described below. Although the
Code authorizes the Treasury Department to provide relief in the event of an
inadvertent termination of REMIC status, no regulations have been issued
implementing this provision. Any such relief, moreover, may be accompanied by
sanctions, such as the imposition of a corporate tax on all or a portion of the
Trust Fund's income for the period in which the requirements for such status are
not satisfied. The Pooling and Servicing Agreement with respect to each REMIC
will include provisions designed to maintain the Trust Fund's status as a REMIC
under the REMIC Provisions.
 
     Characterization of Investments in REMIC Certificates
 
     In general, the REMIC Certificates will be 'real estate assets' within the
meaning of Section 856(c)(4)(A) of the Code and assets described in Section
7701(a)(19)(C) of the Code in the same proportion that the assets of the REMIC
underlying such Certificates would be so treated. Moreover, if 95% or more of
the assets of the REMIC qualify for any of the foregoing treatments at all times
during a calendar year, the REMIC Certificates will qualify for the
corresponding status in their entirety for that calendar year. Interest
(including original issue discount) on the REMIC Regular Certificates and income
allocated to the class of REMIC Residual Certificates will be interest described
in Section 856(c)(3)(B) of the Code to the extent that such Certificates are
treated as 'real estate assets' within the meaning of Section 856(c)(4)(A) of
the Code. In addition, the REMIC Regular Certificates will be 'qualified
mortgages' within the meaning of Section 860G(a)(3) of the Code. The
determination as to the percentage of the REMIC's assets that constitute assets
described in the foregoing sections of the Code will be made with respect to
each calendar quarter based on the average adjusted basis of each category of
the assets held by the REMIC during such calendar quarter. The REMIC will report
those determinations to Certificateholders in the manner and at the times
required by applicable Treasury regulations.
 
     The assets of the REMIC will include, in addition to Loans, payments on
Loans (including temporary investments of such proceeds) held pending
distribution on the REMIC Certificates and may include property acquired by
foreclosure held pending sale, and amounts in reserve accounts. It is unclear
whether property acquired by foreclosure held pending sale, or amounts in
reserve accounts would be considered to be part of the Loans, or whether such
assets (to the extent not invested in assets described in the foregoing
sections) otherwise would receive the same treatment as the Loans for purposes
of all the foregoing sections. In addition, in some instances Loans (including
Additional Collateral Loans) may not be treated entirely as assets described in
the foregoing sections. If the assets of a REMIC include Additional Collateral
Loans, the non-real property collateral, while itself not an asset of the REMIC,
could cause the Loans not to qualify for one or more of such characterizations.
If so, the related Prospectus Supplement will describe the Loans (including
Additional Collateral Loans) that may not be so treated. The REMIC Regulations
do provide, however, that payments on Loans held pending distribution are
considered part of the Loans for purposes of Section 856(c)(4)(A) of the Code.
 
     Tiered REMIC Structures
 
     For certain Series of REMIC Certificates, two or more separate elections
may be made to treat designated portions of the related Trust Fund as REMICs
('Tiered REMICs') for federal income tax purposes. Upon the issuance of any such
Series of REMIC Certificates, Counsel to the Depositor will deliver its opinion
generally to the effect that, assuming compliance with all provisions of the
related Pooling and Servicing Agreement, the Tiered REMICs will each qualify as
a REMIC and the REMIC Certificates issued by the Tiered REMICs will be
considered to evidence ownership of REMIC regular interests or REMIC residual
interests in the related REMIC within the meaning of the REMIC Provisions.
 
     Solely for purposes of determining whether the REMIC Certificates will be
'real estate assets' within the meaning of Section 856(c)(4)(A) of the Code, and
'loans secured by an interest in real property' under Section 7701(a)(19)(C) of
the Code, and whether the income on such Certificates is interest described in
Section 856(c)(3)(B) of the Code, the Tiered REMICs will be treated as one
REMIC.
 
                                       78

<PAGE>
     TAXATION OF OWNERS OF REMIC REGULAR CERTIFICATES
 
     General
 
     Except as otherwise stated in this discussion, REMIC Regular Certificates
will be treated for federal income tax purposes as debt instruments issued by
the REMIC and not as ownership interests in the REMIC or its assets. Moreover,
holders of REMIC Regular Certificates that otherwise report income under a cash
method of accounting will be required to report income with respect to REMIC
Regular Certificates under an accrual method.
 
     Original Issue Discount
 
     Certain REMIC Regular Certificates may be issued with 'original issue
discount' within the meaning of Section 1273(a) of the Code. Any holders of
REMIC Regular Certificates issued with original issue discount generally will be
required to include original issue discount in income as it accrues, in
accordance with the 'constant yield' method described below, in advance of the
receipt of the cash attributable to such income. In addition, Section 1272(a)(6)
of the Code provides special rules applicable to REMIC Regular Certificates and
certain other debt instruments issued with original issue discount. Regulations
have not been issued under that section.
 
     The Code requires that a reasonable prepayment assumption be used with
respect to Loans held by, or Loans underlying Mortgage Assets held by, a REMIC
in computing the accrual of original issue discount on REMIC Regular
Certificates issued by that REMIC, and that adjustments be made in the amount
and rate of accrual of such discount to reflect differences between the actual
prepayment rate and the prepayment assumption. The prepayment assumption is to
be determined in a manner prescribed in Treasury regulations; as noted above,
those regulations have not been issued. The Conference Committee Report (the
'Committee Report') accompanying the Tax Reform Act of 1986 indicates that the
regulations will provide that the prepayment assumption used with respect to a
REMIC Regular Certificate must be the same as that used in pricing the initial
offering of such REMIC Regular Certificate. The prepayment assumption (the
'Prepayment Assumption') used in reporting original issue discount for each
Series of REMIC Regular Certificates will be consistent with this standard and
will be disclosed in the related Prospectus Supplement. However, neither the
Depositor, any Master Servicer nor the Trustee will make any representation that
the Loans will in fact prepay at a rate conforming to the Prepayment Assumption
or at any other rate.
 
     The original issue discount, if any, on a REMIC Regular Certificate will be
the excess of its stated redemption price at maturity over its issue price. The
issue price of a particular class of REMIC Regular Certificates will be the
first cash price at which a substantial amount of REMIC Regular Certificates of
that class is sold (excluding sales to bond houses, brokers and underwriters).
If less than a substantial amount of a particular class of REMIC Regular
Certificates is sold for cash on or prior to the date of their initial issuance
(the 'Closing Date'), the issue price for such class will be the fair market
value of such class on the Closing Date. Under the OID Regulations, the stated
redemption price of a REMIC Regular Certificate is equal to the total of all
payments to be made on such Certificate other than 'qualified stated interest.'
'Qualified stated interest' is interest that is unconditionally payable at least
annually (during the entire term of the instrument) at a single fixed rate, at a
'qualified floating rate,' an 'objective rate,' a combination of a single fixed
rate and one or more 'qualified floating rates' or one 'qualified inverse
floating rate,' or a combination of 'qualified floating rates' that does not
operate in a manner that accelerates or defers interest payments on such REMIC
Regular Certificate.
 
     In the case of REMIC Regular Certificates bearing adjustable interest
rates, the determination of the total amount of original issue discount and the
timing of the inclusion thereof will vary according to the characteristics of
such REMIC Regular Certificates. If the original issue discount rules apply to
such Certificates, the related Prospectus Supplement will describe the manner in
which such rules will be applied with respect to those Certificates in preparing
information returns to the Certificateholders and the IRS.
 
     In addition, if the accrued interest to be paid on the first Distribution
Date is computed with respect to a period that begins prior to the Closing Date,
a portion of the purchase price paid for a REMIC Regular Certificate will
reflect such accrued interest. In such cases, information returns provided to
the Certificateholders and the IRS will be based on the position that the
portion of the purchase price paid for the interest accrued with respect to
periods prior to the Closing Date is treated as part of the overall cost of such
REMIC Regular
 
                                       79
 

<PAGE>

<PAGE>
Certificate (and not as a separate asset the cost of which is recovered entirely
out of interest received on the next Distribution Date) and that the portion of
the interest paid on the first Distribution Date in excess of interest accrued
for a number of days corresponding to the number of days from the Closing Date
to the first Distribution Date should be included in the stated redemption price
of such REMIC Regular Certificate. However, the OID Regulations state that all
or some portion of such accrued interest may be treated as a separate asset the
cost of which is recovered entirely out of interest paid on the first
Distribution Date. It is unclear how an election to do so would be made under
the OID Regulations and whether such an election could be made unilaterally by a
Certificateholder.
 
     Notwithstanding the general definition of original issue discount, original
issue discount on a REMIC Regular Certificate will be considered to be de
minimis if it is less than 0.25% of the stated redemption price of the REMIC
Regular Certificate multiplied by its weighted average life. For this purpose,
the weighted average life of the REMIC Regular Certificate is computed as the
sum of the amounts determined, as to each payment included in the stated
redemption price of such REMIC Regular Certificate, by multiplying (i) the
number of complete years (rounding down for partial years) from the issue date
until such payment is expected to be made (presumably taking into account the
Prepayment Assumption) by (ii) a fraction, the numerator of which is the amount
of payment, and the denominator of which is the stated redemption price at
maturity of such REMIC Regular Certificate. Under the OID Regulations, original
issue discount of only a de minimis amount (other than de minimis original issue
discount attributable to a so-called 'teaser' interest rate or an initial
interest holiday) will be included in income as each payment of stated principal
is made, based on the product of the total amount of such de minimis original
issue discount and a fraction, the numerator of which is the amount of such
principal payment and the denominator of which is the outstanding stated
principal amount of the REMIC Regular Certificate. The OID Regulations also
would permit a Certificateholder to elect to accrue de minimis original issue
discount into income currently based on a constant yield method. See 'Taxation
of Owners of REMIC Regular Certificates -- Market Discount' for a description of
such election under the OID Regulations.
 
     If original issue discount on a REMIC Regular Certificate is in excess of a
de minimis amount, the holder of such Certificate must include in ordinary gross
income the sum of the 'daily portions' of original issue discount for each day
during its taxable year on which it held such REMIC Regular Certificate,
including the purchase date but excluding the disposition date. In the case of
an original holder of a REMIC Regular Certificate, the daily portions of
original issue discount will be determined as follows.
 
     As to each 'accrual period,' that is, unless otherwise stated in the
related Prospectus Supplement, each period that ends on a date that corresponds
to a Distribution Date and begins on the first day following the immediately
preceding accrual period (or in the case of the first such period, begins on the
Closing Date), a calculation will be made of the portion of the original issue
discount that accrued during such accrual period. The portion of original issue
discount that accrues in any accrual period will equal the excess, if any, of
(i) the sum of (A) the present value, as of the end of the accrual period, of
all of the distributions remaining to be made on the REMIC Regular Certificate,
if any, in future periods and (B) the distributions made on such REMIC Regular
Certificate during the accrual period of amounts included in the stated
redemption price, over (ii) the adjusted issue price of such REMIC Regular
Certificate at the beginning of the accrual period. The present value of the
remaining distributions referred to in the preceding sentence will be calculated
(i) assuming that distributions on the REMIC Regular Certificate will be
received in future periods based on the Loans being prepaid at a rate equal to
the Prepayment Assumption, and in the case of Mortgage Assets other than Loans,
that distributions will be made with respect to each Mortgage Asset in
accordance with the participation agreement or other organizational document
under which such Mortgage Asset was issued, and (ii) using a discount rate equal
to the original yield to maturity of the Certificate. For these purposes, the
original yield to maturity of the Certificate will be calculated based on its
issue price and assuming that distributions on the Certificate will be made in
all accrual periods based on the Loans being prepaid at a rate equal to the
Prepayment Assumption, and in the case of Mortgage Assets other than Loans, that
distributions will be made with respect to each Mortgage Asset in accordance
with the participation agreement or other organizational document under which
such Mortgage Asset was issued. The adjusted issue price of a REMIC Regular
Certificate at the beginning of any accrual period will equal the issue price of
such Certificate, increased by the aggregate amount of original issue discount
that accrued with respect to such Certificate in prior accrual periods, and
reduced by the amount of any distributions made on such REMIC Regular
Certificate in prior accrual periods of amounts included in the stated
redemption price. The original issue discount accruing during any accrual
period, computed as described above,
 
                                       80
 

<PAGE>

<PAGE>
will be allocated ratably to each day during the accrual period to determine the
daily portion of original issue discount for such day.
 
     A subsequent purchaser of a REMIC Regular Certificate that purchases such
Certificate at a cost (excluding any portion of such cost attributable to
accrued qualified stated interest) less than its remaining stated redemption
price will also be required to include in gross income the daily portions of any
original issue discount with respect to such Certificate. However, each such
daily portion will be reduced, if such cost is in excess of the REMIC Regular
Certificate's 'adjusted issue price,' in proportion to the ratio such excess
bears to the aggregate original issue discount remaining to be accrued on such
REMIC Regular Certificate. The adjusted issue price of a REMIC Regular
Certificate on any given day equals (i) the adjusted issue price (or, in the
case of the first accrual period, the issue price) of such Certificate at the
beginning of the accrual period which includes such day plus (ii) the daily
portions of original issue discount for all days during such accrual period
prior to such day minus (iii) any principal payments made during such accrual
period prior to such day with respect to such certificate.
 
     Market Discount
 
     A Certificateholder that purchases a REMIC Regular Certificate at a market
discount, that is, in the case of a REMIC Regular Certificate issued without
original issue discount, at a purchase price less than its remaining stated
principal amount, or in the case of a REMIC Regular Certificate issued with
original issue discount, at a purchase price less than its adjusted issue price
will recognize gain upon receipt of each distribution representing stated
redemption price. In particular, under Section 1276 of the Code such a
Certificateholder generally will be required to allocate the portion of each
such distribution representing stated redemption price first to accrued market
discount not previously included in income, and to recognize ordinary income to
that extent. A Certificateholder may elect to include market discount in income
currently as it accrues rather than including it on a deferred basis in
accordance with the foregoing. If made, such election will apply to all market
discount bonds acquired by such Certificateholder on or after the first day of
the first taxable year to which such election applies. In addition, the OID
Regulations permit a Certificateholder to elect to accrue all interest, discount
(including de minimis market or original issue discount) and premium in income
as interest, based on a constant yield method. If such an election were made
with respect to a REMIC Regular Certificate with market discount, the
Certificateholder would be deemed to have made an election to include currently
market discount in income with respect to all other debt instruments having
market discount that such Certificateholder acquires during the taxable year of
the election or thereafter. Similarly, a Certificateholder that made this
election for a Certificate that is acquired at a premium would be deemed to have
made an election to amortize bond premium with respect to all debt instruments
having amortizable bond premium that such Certificateholder owns or acquires.
See 'Taxation of Owners of REMIC Regular Certificates -- Premium.' Each of these
elections to accrue interest, discount and premium with respect to a Certificate
on a constant yield method or as interest may not be revoked without the consent
of the IRS.
 
     However, market discount with respect to a REMIC Regular Certificate will
be considered to be de minimis for purposes of Section 1276 of the Code if such
market discount is less than 0.25% of the remaining stated redemption price of
such REMIC Regular Certificate multiplied by the number of complete years to
maturity remaining after the date of its purchase. In interpreting a similar
rule with respect to original issue discount on obligations payable in
installments, the OID Regulations refer to the weighted average maturity of
obligations, and it is likely that the same rule will be applied with respect to
market discount, presumably taking into account the Prepayment Assumption. If
market discount is treated as de minimis under this rule, it appears that the
actual discount would be treated in a manner similar to original issue discount
of a de minimis amount. See 'Taxation of Owners of REMIC Regular
Certificates -- Original Issue Discount.' Such treatment may result in discount
being included in income at a slower rate than discount would be required to be
included in income using the method described above.
 
     Section 1276(b)(3) of the Code specifically authorizes the Treasury
Department to issue regulations providing for the method for accruing market
discount on debt instruments, the principal of which is payable in more than one
installment. Until regulations are issued by the Treasury Department certain
rules described in the Committee Report should apply. The Committee Report
indicates that in each accrual period market discount on REMIC Regular
Certificates accrues, at the Certificateholder's option: (i) on the basis of a
constant yield method, (ii) in the case of a REMIC Regular Certificate issued
without original issue discount, in an amount that
 
                                       81
 

<PAGE>

<PAGE>
bears the same ratio to the total remaining market discount as the stated
interest paid in the accrual period bears to the total amount of stated interest
remaining to be paid on the REMIC Regular Certificate as of the beginning of the
accrual period, or (iii) in the case of a REMIC Regular Certificate issued with
original issue discount, in an amount that bears the same ratio to the total
remaining market discount as the original issue discount accrued in the accrual
period bears to the total original issue discount remaining on the REMIC Regular
Certificate at the beginning of the accrual period. Moreover, the Prepayment
Assumption used in calculating the accrual of original issue discount is also
used in calculating the accrual of market discount. Because the regulations
referred to in this paragraph have not been issued, it is not possible to
predict what effect such regulations might have on the tax treatment of a REMIC
Regular Certificate purchased at a discount in the secondary market.
 
     To the extent that REMIC Regular Certificates provide for monthly or other
periodic distributions throughout their term, the effect of these rules may be
to require market discount to be includible in income at a rate that is not
significantly slower than the rate at which such discount would accrue if it
were original issue discount. Moreover, in any event a holder of a REMIC Regular
Certificate generally will be required to treat a portion of any gain on the
sale or exchange of such Certificate as ordinary income to the extent of the
market discount accrued to the date of disposition under one of the foregoing
methods, less any accrued market discount previously reported as ordinary
income.
 
     Further, under Section 1277 of the Code a holder of a REMIC Regular
Certificate may be required to defer a portion of its interest deductions for
the taxable year attributable to any indebtedness incurred or continued to
purchase or carry a REMIC Regular Certificate purchased with market discount.
For these purposes, the de minimis rule referred to above applies. Any such
deferred interest expense would not exceed the market discount that accrues
during such taxable year and is, in general, allowed as a deduction not later
than the year in which such market discount is includible in income. If such
holder elects to include market discount in income currently as it accrues on
all market discount instruments acquired by such holder in that taxable year or
thereafter, the interest deferral rule described above will not apply.
 
     Premium
 
     A REMIC Regular Certificate purchased at a cost (excluding any portion of
such cost attributable to accrued qualified stated interest) greater than its
remaining stated redemption price will be considered to be purchased at a
premium. The holder of such a REMIC Regular Certificate may elect under Section
171 of the Code to amortize such premium under the constant yield method over
the life of the Certificate. If made, such an election will apply to all debt
instruments having amortizable bond premium that the holder owns or subsequently
acquires. Amortizable premium will be treated as an offset to interest income on
the related debt instrument rather than as a separate interest deduction. By
analogy to recently finalized bond premium regulations, any allocable premium in
excess of the interest income may be deductible to the extent of prior accruals
of interest. The OID Regulations also permit Certificateholders to elect to
include all interest, discount and premium in income based on a constant yield
method, further treating such Certificateholder as having made the election to
amortize premium generally. See 'Taxation of Owners of REMIC Regular
Certificates -- Market Discount.' The Committee Report states that the same
rules that apply to accrual of market discount (which rules presumably will
require use of a prepayment assumption in accruing market discount with respect
to REMIC Regular Certificates without regard to whether such Certificates have
original issue discount) will also apply in amortizing bond premium under
Section 171 of the Code.
 
     Realized Losses
 
     Under Section 166 of the Code, both corporate holders of the REMIC Regular
Certificates and noncorporate holders of the REMIC Regular Certificates that
acquire such Certificates in connection with a trade or business should be
allowed to deduct, as ordinary losses, any losses sustained during a taxable
year in which their Certificates become wholly or partially worthless as the
result of one or more realized losses on the Loans. However, it appears that a
noncorporate holder that does not acquire a REMIC Regular Certificate in
connection with a trade or business will not be entitled to deduct a loss under
Section 166 of the Code until such holder's Certificate becomes wholly worthless
(i.e., until its outstanding principal balance has been reduced to zero) and
that the loss will be characterized as a short-term capital loss.
 
                                       82
 

<PAGE>

<PAGE>
     Each holder of a REMIC Regular Certificate will be required to accrue
interest and original issue discount with respect to such Certificate, without
giving effect to any reductions in distributions attributable to defaults or
delinquencies on the Loans until it can be established that any such reduction
ultimately will not be recoverable. As a result, the amount of taxable income
reported in any period by the holder of a REMIC Regular Certificate could exceed
the amount of economic income actually realized by the holder in such period.
Although the holder of a REMIC Regular Certificate eventually will recognize a
loss or reduction in income attributable to previously accrued and included
income that as the result of a realized loss ultimately will not be realized,
the law is unclear with respect to the timing and character of such loss or
reduction in income.
 
Taxation of Owners of REMIC Residual Certificates
 
GENERAL
 
     Although a REMIC is a separate entity for federal income tax purposes, a
REMIC generally is not subject to entity-level taxation, except with regard to
prohibited transactions and certain other transactions. See ' -- Prohibited
Transactions and Other Possible REMIC Taxes' below. Rather, the taxable income
or net loss of a REMIC is generally taken into account by the Holder of the
REMIC Residual Certificates. Accordingly, the REMIC Residual Certificates will
be subject to tax rules that differ significantly from those that would apply if
the REMIC Residual Certificates were treated for federal income tax purposes as
direct ownership interests in the Loans or as debt instruments issued by the
REMIC.
 
     A holder of a REMIC Residual Certificate generally will be required to
report its daily portion of the taxable income or, subject to the limitations
noted in this discussion, the net loss of the REMIC for each day during a
calendar quarter that such holder owned such REMIC Residual Certificate. For
this purpose, the taxable income or net loss of the REMIC will be allocated to
each day in the calendar quarter ratably using a '30 days per month/90 days per
quarter/360 days per year' convention unless otherwise disclosed in the related
Prospectus Supplement. The daily amounts so allocated will then be allocated
among the REMIC Residual Certificateholders in proportion to their respective
ownership interests on such day. Any amount included in the gross income of or
allowed as a loss to any REMIC Residual Certificateholder by virtue of this
paragraph will be treated as ordinary income or loss. The taxable income of the
REMIC will be determined under the rules described below in 'Taxable Income of
the REMIC' and will be taxable to the REMIC Residual Certificateholders without
regard to the timing or amount of cash distributions by the REMIC. Ordinary
income derived from REMIC Residual Certificates will be 'portfolio income' for
purposes of the taxation of taxpayers subject to limitations under Section 469
of the Code on the deductibility of 'passive activity losses.'
 
     A holder of a REMIC Residual Certificate that purchased such Certificate
from a prior holder also will be required to report on its federal income tax
return amounts representing its daily share of the taxable income (or net loss)
of the REMIC for each day that it holds such Certificate. Those daily amounts
generally will equal the amounts of taxable income or net loss determined as
described above. The Committee Report indicates that certain modifications of
the general rules may be made, by regulations or otherwise, to reduce (or
increase) the income of a REMIC Residual Certificateholder that purchased such
Certificate from a prior holder of such Certificate at a price greater than (or
less than) the adjusted basis (as defined below) such REMIC Residual Certificate
would have had in the hands of an original holder of such Certificate. The REMIC
Regulations, however, do not provide for any such modifications.
 
     Any payments received by a holder of a REMIC Residual Certificate in
connection with the acquisition of such REMIC Residual Certificate will be taken
into account in determining the income of such holder for federal income tax
purposes. Although it appears likely that any such payment would be includible
in income immediately upon its receipt, the IRS might assert that such payment
should be included in income over time according to an amortization schedule or
according to some other method. Because of the uncertainty concerning the
treatment of such payments, holders of REMIC Residual Certificates should
consult their tax advisors concerning the treatment of such payments for income
tax purposes.
 
     The amount of income REMIC Residual Certificateholders will be required to
report (or the tax liability associated with such income) may exceed the amount
of cash distributions received from the REMIC for the corresponding period.
Consequently, REMIC Residual Certificateholders should have other sources of
funds sufficient to pay any federal income taxes due as a result of their
ownership of REMIC Residual Certificates or unrelated deductions against which
income may be offset, subject to the rules relating to 'excess inclusions'
 
                                       83
 

<PAGE>

<PAGE>
and 'noneconomic' residual interests discussed below. The fact that the tax
liability associated with the income allocated to REMIC Residual
Certificateholders may exceed the cash distributions received by such REMIC
Residual Certificateholders for the corresponding period may significantly
adversely affect such REMIC Residual Certificateholders' after-tax rate of
return. Such disparity between income and distributions may not be offset by
corresponding losses or reductions of income attributable to the REMIC Residual
Certificateholder until subsequent tax years and, then, may not be completely
offset due to changes in the Code, tax rates or character of the income or loss.
 
     Taxable Income of the REMIC
 
     The taxable income of the REMIC will equal the income from the Loans and
other assets of the REMIC plus any cancellation of indebtedness income due to
the allocation of realized losses to REMIC Regular Certificates, less the
deductions allowed to the REMIC for interest (including original issue discount
and reduced by amortization of any premium on issuance) on the REMIC Regular
Certificates (and any other class of REMIC Certificates constituting 'regular
interests' in the REMIC not offered hereby), amortization of any premium on the
Loans, bad debt losses with respect to the Loans and, except as described below,
servicing, administrative and other expenses.
 
     For purposes of determining its taxable income, the REMIC will have an
initial aggregate basis in its assets equal to the sum of the issue prices of
all REMIC Certificates (or, if a class of REMIC Certificates is not sold
initially, their fair market values). The issue price of any REMIC Certificates
offered hereby will be determined in the manner described above under
' -- Taxation of Owners of REMIC Regular Certificates -- Original Issue
Discount.' The issue price of a REMIC Certificate received in exchange for an
interest in the Loans or other property will equal the fair market value of such
interests in the Loans or other property. Accordingly, if one or more classes of
REMIC Certificates are retained initially rather than sold, the Trustee may be
required to estimate the fair market value of such interests in order to
determine the basis of the REMIC in the Loans and other property held by the
REMIC.
 
     Subject to possible application of the de minimis rules, the method of
accrual by the REMIC of original issue discount income and market discount
income with respect to Loans that it holds will be equivalent to the method for
accruing original issue discount income for holders of REMIC Regular
Certificates (that is, under the constant yield method taking into account the
Prepayment Assumption). However, a REMIC that acquires loans at a market
discount must include such market discount in income currently as it accrues, on
a constant yield basis. See ' -- Taxation of Owners of REMIC Regular
Certificates' above, which describes a method for accruing such discount income
that is analogous to that required to be used by a REMIC as to Loans with market
discount that it holds.
 
     A Loan will be deemed to have been acquired with discount (or premium) to
the extent that the REMIC's basis therein, determined as described above, is
less than (or greater than) its stated redemption price. Any such discount will
be includible in the income of the REMIC as it accrues, in advance of receipt of
the cash attributable to such income, under a method similar to the method
described above for accruing original issue discount on the REMIC Regular
Certificates. It is anticipated that each REMIC will elect under Section 171 of
the Code to amortize any premium on the Loans. Premium on any Loan to which such
election applies may be amortized under a constant yield method, presumably
taking into account the Prepayment Assumption. Further, such an election would
not apply to any Loan originated on or before September 27, 1985. Instead,
premium on such a Loan should be allocated among the principal payments thereon
and be deductible by the REMIC as those payments become due or upon the
prepayment of such Loan.
 
     A REMIC will be allowed deductions for interest (including original issue
discount) on the REMIC Regular Certificates (including any other class of REMIC
Certificates constituting 'regular interests' in the REMIC not offered hereby)
equal to the deductions that would be allowed if the REMIC Regular Certificates
(including any other class of REMIC Certificates constituting 'regular
interests' in the REMIC not offered hereby) were indebtedness of the REMIC.
Original issue discount will be considered to accrue for this purpose as
described above under ' -- Taxation of Owners of REMIC Regular
Certificates -- Original Issue Discount,' except that the de minimis rule and
the adjustments for subsequent holders of REMIC Regular Certificates (including
any other class of REMIC Certificates constituting 'regular interests' in the
REMIC not offered hereby) described therein will not apply.
 
                                       84
 

<PAGE>

<PAGE>
     If a class of REMIC Regular Certificates is issued at a price in excess of
the stated redemption price of such class (such excess 'Issue Premium'), the net
amount of interest deductions that are allowed the REMIC in each taxable year
with respect to the REMIC Regular Certificates of such class will be reduced by
an amount equal to the portion of the Issue Premium that is considered to be
amortized or repaid in that year. Although the matter is not entirely certain,
it is likely that Issue Premium would be amortized under a constant yield method
in a manner analogous to the method of accruing original issue discount
described above under ' -- Taxation of Owners of REMIC Regular
Certificates -- Original Issue Discount.'
 
     As a general rule, the taxable income of a REMIC will be determined in the
same manner as if the REMIC were an individual having the calendar year as its
taxable year and using the accrual method of accounting. However, no item of
income, gain, loss or deduction allocable to a prohibited transaction will be
taken into account. See ' -- Prohibited Transactions and Other Possible REMIC
Taxes' below. Further, the limitation on miscellaneous itemized deductions
imposed on individuals by Section 67 of the Code (which allows such deductions
only to the extent they exceed in the aggregate two percent of the taxpayer's
adjusted gross income) will not be applied at the REMIC level so that the REMIC
will be allowed deductions for servicing, administrative and other non-interest
expenses in determining its taxable income. All such expenses will be allocated
as a separate item to the holders of REMIC Certificates, subject to the
limitation of Section 67 of the Code. See ' -- Possible Pass-Through of
Miscellaneous Itemized Deductions.' If the deductions allowed to the REMIC
exceed its gross income for a calendar quarter, such excess will be the net loss
for the REMIC for that calendar quarter.
 
     Basis Rules, Net Losses and Distributions
 
     The adjusted basis of a REMIC Residual Certificate will be equal to the
amount paid for such Certificate, increased by amounts included in the income of
the REMIC Residual Certificateholder and decreased (but not below zero) by
distributions made, and by net losses allocated, to such REMIC Residual
Certificateholder.
 
     A REMIC Residual Certificateholder is not allowed to take into account any
net loss for any calendar quarter to the extent such net loss exceeds such REMIC
Residual Certificateholder's adjusted basis in its REMIC Residual Certificate as
of the close of such calendar quarter (determined without regard to such net
loss). Any loss that is not currently deductible by reason of this limitation
may be carried forward indefinitely to future calendar quarters and, subject to
the same limitation, may be used only to offset income from the REMIC Residual
Certificate. The ability of REMIC Residual Certificateholders to deduct net
losses may be subject to additional limitations under the Code, as to which
REMIC Residual Certificateholders should consult their tax advisors.
 
     Any distribution on a REMIC Residual Certificate will be treated as a
non-taxable return of capital to the extent it does not exceed the holder's
adjusted basis in such Certificate. To the extent a distribution on a REMIC
Residual Certificate exceeds such adjusted basis, it will be treated as gain
from the sale of such Certificate. Holders of certain REMIC Residual
Certificates may be entitled to distributions early in the term of the related
REMIC under circumstances in which their bases in such REMIC Residual
Certificates will not be sufficiently large that such distributions will be
treated as nontaxable returns of capital. Their bases in such REMIC Residual
Certificates will initially equal the amount paid for such REMIC Residual
Certificates and will be increased by their allocable shares of the taxable
income of the REMIC. However, such bases increases may not occur until the end
of the calendar quarter, or perhaps the end of the calendar year, with respect
to which such REMIC taxable income is allocated to the REMIC Residual
Certificateholders. To the extent such REMIC Residual Certificateholders'
initial bases are less than the distributions to such REMIC Residual
Certificateholders, and increases in such initial bases either occur after such
distributions or (together with their initial bases) are less than the amount of
such distributions, gain will be recognized to such REMIC Residual
Certificateholders on such distributions and will be treated as gain from the
sale of their REMIC Residual Certificates.
 
     The effect of these rules is that a REMIC Residual Certificateholder may
not amortize its basis in a REMIC Residual Certificate, but may only recover its
basis through distributions, through the deduction of any net losses of the
REMIC or upon the sale of its REMIC Residual Certificate. See ' -- Sales of
REMIC Certificates,' below. For a discussion of possible modifications of these
rules that may require adjustments to income of a holder of a REMIC Residual
Certificate other than an original holder in order to reflect any difference
between the cost of such REMIC Residual Certificate to such REMIC Residual
Certificateholder and the adjusted basis such REMIC
 
                                       85
 

<PAGE>

<PAGE>
Residual Certificate would have had in the hands of an original holder, see
' -- Taxation of Owners of REMIC Residual Certificates -- General.'
 
     Excess Inclusions
 
     Any 'excess inclusions' with respect to a REMIC Residual Certificate will
be subject to federal income tax in all events.
 
     In general, the 'excess inclusions' with respect to a REMIC Residual
Certificate for any calendar quarter will be the excess, if any, of (i) the
daily portions of REMIC taxable income allocable to such REMIC Residual
Certificate over (ii) the sum of the 'daily accruals' (as defined below) for
each day during such quarter that such REMIC Residual Certificate was held by
the REMIC Residual Certificateholder. The daily accruals of a REMIC Residual
Certificateholder will be determined by allocating to each day during a calendar
quarter its ratable portion of the product of the 'adjusted issue price' of the
REMIC Residual Certificate at the beginning of the calendar quarter and 120% of
the 'long-term Federal rate' in effect on the Closing Date. For this purpose,
the adjusted issue price of a REMIC Residual Certificate as of the beginning of
any calendar quarter will be equal to the issue price of the REMIC Residual
Certificate, increased by the sum of the daily accruals for all prior quarters
and decreased (but not below zero) by any distributions made with respect to
such REMIC Residual Certificate before the beginning of such quarter. The issue
price of a REMIC Residual Certificate is the initial offering price to the
public (excluding bond houses and brokers) at which a substantial amount of the
REMIC Residual Certificates were sold. The 'long-term Federal rate' is an
average of current yields on Treasury securities with a remaining term of
greater than nine years, computed and published monthly by the IRS.
 
     For REMIC Residual Certificateholders, an excess inclusion (i) will not be
permitted to be offset by deductions, losses or loss carryovers from other
activities, (ii) will be treated as 'unrelated business taxable income' to an
otherwise tax-exempt organization and (iii) will not be eligible for any rate
reduction or exemption under any applicable tax treaty with respect to the 30%
United States withholding tax imposed on distributions to REMIC Residual
Certificateholders that are foreign investors. See, however, ' -- Foreign
Investors in REMIC Certificates,' below.
 
     Recently enacted provisions governing the relationship between excess
inclusions and the alternative minimum tax provide that (i) the alternative
minimum taxable income of the taxpayer is based on the taxpayer's regular
taxable income computed without regard to the rule that taxable income cannot be
less than the amount of excess inclusions, (ii) the alternative minimum taxable
of a taxpayer for a taxable year cannot be less than the amount of excess
inclusions for that year, and (iii) the amount of any alternative minimum tax
net operating loss is computed without regard to any excess inclusions.
 
     Under Treasury regulations yet to be issued, in the case of any REMIC
Residual Certificates held by a real estate investment trust, the aggregate
excess inclusions with respect to such Certificates, reduced (but not below
zero) by the real estate investment trust taxable income (within the meaning of
Section 857(b)(2) of the Code, excluding any net capital gain), will be
allocated among the shareholders of 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 Certificate
as if held directly by such shareholder. A similar rule will apply with respect
to regulated investment companies, common trust funds and certain cooperatives.
 
     Noneconomic REMIC Residual Certificates
 
     Under the REMIC Regulations, transfers of 'noneconomic' REMIC Residual
Certificates will be disregarded for all federal income tax purposes if 'a
significant purpose of the transfer was to enable the transferor to impede the
assessment or collection of tax.' If such transfer is disregarded, the purported
transferor will continue to remain liable for any taxes due with respect to the
income on such 'noneconomic' REMIC Residual Certificate. The REMIC Regulations
provide that a REMIC Residual Certificate is noneconomic unless, based on the
Prepayment Assumption and on any required or permitted clean up calls or
required qualified liquidation provided for in the REMIC's organizational
documents, (1) the present value of the expected future distributions
(discounted using the 'applicable Federal rate' for obligations whose term ends
on the close of the last quarter in which excess inclusions are expected to
accrue with respect to the REMIC Residual Certificate, which rate is computed
and published monthly by the IRS) on the REMIC Residual Certificate equals at
least the present value of the expected tax on the anticipated excess
inclusions, and (2) the
 
                                       86

transferor reasonably expects that for each anticipated excess inclusion the
transferee will receive distributions with respect to the REMIC Residual
Certificate at or after the time the taxes accrue on the anticipated excess
inclusions in an amount sufficient to satisfy the accrued taxes. Accordingly,
all transfers of REMIC Residual Certificates that may constitute noneconomic
residual interests will be subject to certain restrictions under the terms of
the related Pooling and Servicing Agreement that are intended to reduce the
possibility of any such transfer being disregarded. Such restrictions will
require each party to a transfer to provide an affidavit that no purpose of such
transfer is to impede the assessment or collection of tax, including certain
representations as to the financial condition of the prospective transferee, as
to which the transferor will also be required to make a reasonable investigation
to determine such transferee's historic payments of its debts and ability to
continue to pay its debts as they come due in the future. Prior to purchasing a
REMIC Residual Certificate, prospective purchasers should consider the
possibility that a purported transfer of such REMIC Residual Certificate by such
a purchaser to another purchaser at some future date might be disregarded in
accordance with the above-described rules, which would result in the retention
of tax liability by such purchaser.
 
     The related Prospectus Supplement will disclose whether offered REMIC
Residual Certificates may be considered 'noneconomic' residual interests under
the REMIC Regulations; provided, however, that any disclosure that a REMIC
Residual Certificate will not be considered 'noneconomic' will be based upon
certain assumptions, and the Depositor will make no representation that a REMIC
Residual Certificate will not be considered 'noneconomic' for purposes of the
above-described rules. See ' -- Foreign Investors In REMIC Certificates -- REMIC
Residual Certificates' below for additional restrictions applicable to transfers
of certain REMIC Residual Certificates to foreign persons.
 
     Mark-to-Market Rules
 
     On December 24, 1996, the IRS released final regulations (the
'Mark-to-Market Regulations') relating to the requirement that a securities
dealer mark to market securities held for sale to customers. This mark-to-market
requirement applies to all securities owned by a dealer, except to the extent
that the dealer has specifically identified a security as held for investment.
The Mark-to-Market Regulations provide that for purposes of this mark-to-market
requirement, any REMIC Residual Certificate acquired after January 4, 1995 will
not be treated as a security and therefore generally may not be marked to
market.
 
     Possible Pass-Through of Miscellaneous Itemized Deductions
 
     Fees and expenses of a REMIC generally will be allocated to the holders of
the related REMIC Residual Certificates. The applicable Treasury regulations
indicate, however, that in the case of a REMIC that is similar to a single class
grantor trust, all or a portion of such fees and expenses should be allocated to
the holders of the related REMIC Regular Certificates. Unless otherwise stated
in the related Prospectus Supplement, such fees and expenses will be allocated
to holders of the related REMIC Residual Certificates in their entirety and not
to the holders of the related REMIC Regular Certificates.
 
     With respect to REMIC Residual Certificates or REMIC Regular Certificates
the holders of which receive an allocation of fees and expenses in accordance
with the preceding discussion, if any holder thereof is an individual, estate or
trust, or a 'pass-through entity' beneficially owned by one or more individuals,
estates or trusts, (i) an amount equal to such individual's, estate's or trust's
share of such fees and expenses will be added to the gross income of such holder
and (ii) such individual's, estate's or trust's share of such fees and expenses
will be treated as a miscellaneous itemized deduction allowable subject to the
limitation of Section 67 of the Code, which permits such deductions only to the
extent they exceed in the aggregate two percent of a taxpayer's adjusted gross
income. For taxable years beginning after December 31, 1997, in the case of a
partnership that has 100 or more partners and elects to be treated as an
'electing large partnership,' 70 percent of such partnership's miscellaneous
itemized deductions will be disallowed, although the remaining deductions will
generally be allowed at the partnership level and will not be subject to the 2
percent floor that would otherwise be applicable to individual partners. In
addition, Section 68 of the Code provides that the amount of itemized deductions
otherwise allowable for an individual whose adjusted gross income exceeds a
specified amount will be reduced by the lesser of (i) 3% of the excess of the
individual's adjusted gross income over such amount or (ii) 80% of the amount of
itemized deductions otherwise allowable for the taxable year. The amount of
additional taxable income reportable by holders of such Certificates that are
subject to the limitations of either Section 67 or Section 68 of the Code may be
substantial. Furthermore, in determining the alternative minimum
 
                                       87
 

<PAGE>

<PAGE>
taxable income of such a holder of a REMIC Certificate that is an individual,
estate or trust, or a 'pass-through entity' beneficially owned by one or more
individuals, estates or trusts, no deduction will be allowed for such holder's
allocable portion of servicing fees and other miscellaneous itemized deductions
of the REMIC, even though an amount equal to the amount of such fees and other
deductions will be included in such holder's gross income. Accordingly, such
REMIC Certificates may not be appropriate investments for individuals, estates
or trusts, or pass-through entities beneficially owned by one or more
individuals, estates or trusts. Such prospective investors should carefully
consult with their own tax advisors prior to making an investment in such
Certificates.
 
     Sales of REMIC Certificates
 
     If a REMIC Certificate is sold, the selling Certificateholder will
recognize gain or loss equal to the difference between the amount realized on
the sale and its adjusted basis in the REMIC Regular Certificate. The adjusted
basis of a REMIC Regular Certificate generally will equal the cost of such REMIC
Regular Certificate to such Certificateholder, increased by income reported by
such Certificateholder with respect to such REMIC Regular Certificate (including
original issue discount and market discount income) and reduced (but not below
zero) by distributions on such REMIC Regular Certificate received by such
Certificateholder and by any amortized premium. The adjusted basis of a REMIC
Residual Certificate will be determined as described under ' -- Taxation of
Owners of REMIC Residual Certificates -- Basis Rules, Net Losses and
Distributions.' Except as provided in the following five paragraphs, any such
gain or loss will be capital gain or loss provided such REMIC Certificate is
held as a capital asset (generally property held for investment) within the
meaning of Section 1221 of the Code.
 
     Gain from the sale of a REMIC Regular Certificate that might otherwise be
capital gain will be treated as ordinary income to the extent such gain does not
exceed the excess, if any, of (i) the amount that would have been includible in
the seller's income with respect to such REMIC Regular Certificate assuming that
income had accrued thereon at a rate equal to 110% of the 'applicable Federal
rate' (generally a rate based on an average of current yields on Treasury
securities having a maturity comparable to that of the Certificate based on the
application of the Prepayment Assumption to such Certificate, which rate is
computed and published monthly by the IRS), determined as of the date of
purchase of such Certificate, over (ii) the amount of ordinary income actually
includible in the seller's income prior to such sale. In addition, gain
recognized on the sale of a REMIC Regular Certificate by a seller who purchased
such Certificate at a market discount will be taxable as ordinary income in an
amount not exceeding the portion of such discount that accrued during the period
such REMIC Certificate was held by such holder, reduced by any market discount
included in income under the rules described above under ' -- Taxation of Owners
of REMIC Regular Certificates -- Market Discount and -- Premium.'
 
     REMIC Certificates will be 'evidences of indebtedness' within the meaning
of Section 582(c)(1) of the Code, so that gain or loss recognized from the sale
of a REMIC Certificate by a bank or thrift institution to which such section
applies will be ordinary income or loss.
 
     A portion of any gain from the sale of a REMIC Regular Certificate that
might otherwise be capital gain may be treated as ordinary income to the extent
that such Certificate is held as part of a 'conversion transaction' within the
meaning of Section 1258 of the Code. A conversion transaction generally is one
in which the taxpayer has taken two or more positions in the same or similar
property that reduce or eliminate market risk, if substantially all of the
taxpayer's return is attributable to the time value of the taxpayer's net
investment in such transaction. The amount of gain so realized in a conversion
transaction that is recharacterized as ordinary income generally will not exceed
the amount of interest that would have accrued on the taxpayer's net investment
at 120% of the appropriate 'applicable Federal rate' (which rate is computed and
published monthly by the IRS) at the time the taxpayer enters into the
conversion transaction, subject to appropriate reduction for prior inclusion of
interest and other ordinary income items from the transaction.
 
     Finally, a taxpayer may elect to have net capital gain taxed at ordinary
income rates rather than capital gains rates in order to include such net
capital gain in total net investment income for the taxable year, for purposes
of the rule that limits the deduction of interest on indebtedness incurred to
purchase or carry property held for investment to a taxpayer's net investment
income.
 
     Except as may be provided in Treasury regulations yet to be issued, if the
seller of a REMIC Residual Certificate reacquires a REMIC Residual Certificate,
or acquires any other residual interest in a REMIC or any
 
                                       88
 

<PAGE>

<PAGE>
similar interest in a 'taxable mortgage pool' (as defined in Section 7701(i) of
the Code) during the period beginning six months before, and ending six months
after, the date of such sale, such sale will be subject to the 'wash sale' rules
of Section 1091 of the Code. In that event, any loss realized by the Residual
Certificateholder on the sale will not be deductible, but instead will be added
to such REMIC Residual Certificateholder's adjusted basis in the newly acquired
asset.
 
     Prohibited Transactions and Other Possible REMIC Taxes
 
     The Code imposes a tax on REMICs equal to 100% of the net income derived
from 'prohibited transactions' (a 'Prohibited Transaction Tax'). In general,
subject to certain specified exceptions, a prohibited transaction means the
disposition of a Loan, the receipt of income from a source other than a Loan or
certain other permitted investments, the receipt of compensation for services,
or gain from the disposition of an asset purchased with the payments on the
Loans for temporary investment pending distribution on the REMIC Certificates.
It is not anticipated that any REMIC will engage in any prohibited transactions
in which it would recognize a material amount of net income.
 
     In addition, certain contributions to a REMIC made after the day on which
the REMIC issues all of its interests could result in the imposition of a tax on
the REMIC equal to 100% of the value of the contributed property (a
'Contributions Tax'). Each Pooling and Servicing Agreement will include
provisions designed to prevent the acceptance of any contributions that would be
subject to such tax.
 
     REMICs also are subject to federal income tax at the highest corporate rate
on 'net income from foreclosure property,' determined by reference to the rules
applicable to real estate investment trusts. 'Net income from foreclosure
property' generally means gain from the sale of a foreclosure property that is
inventory property and gross income from foreclosure property other than
qualifying rents and other qualifying income for a real estate investment trust.
Unless otherwise disclosed in the related Prospectus Supplement, it is not
anticipated that any REMIC will recognize 'net income from foreclosure property'
subject to federal income tax.
 
     Unless otherwise stated in the related Prospectus Supplement, and to the
extent permitted by then applicable laws, any Prohibited Transactions Tax,
Contributions Tax, tax on 'net income from foreclosure property' or state or
local income or franchise tax that may be imposed on the REMIC will be borne by
the related Master Servicer or Trustee, in either case out of its own funds,
provided that the Master Servicer or the Trustee, as the case may be, has
sufficient assets to do so, and provided further that such tax arises out of a
breach of the Master Servicer's or the Trustee's obligations, as the case may
be, under the related Pooling and Servicing Agreement and in respect of
compliance with applicable laws and regulations. Any such tax not borne by the
Master Servicer or the Trustee will be charged against the related Trust Fund,
resulting in a reduction in amounts payable to holders of the related REMIC
Certificates.
 
     Tax and Restrictions on Transfers of REMIC Residual Certificates to Certain
Organizations.
 
     If a REMIC Residual Certificate is transferred to a 'disqualified
organization' (as defined below), a tax would be imposed in an amount
(determined under the REMIC Regulations) equal to the product of (i) the present
value (discounted using the 'applicable Federal rate' for obligations whose term
ends on the close of the last quarter in which excess inclusions are expected to
accrue with respect to the REMIC Residual Certificate, which rate is computed
and published monthly by the IRS) of the total anticipated excess inclusions
with respect to such REMIC Residual Certificate for periods after the transfer
and (ii) the highest marginal federal income tax rate applicable to
corporations. The anticipated excess inclusions must be determined as of the
date that the REMIC Residual Certificate is transferred and must be based on
events that have occurred up to the time of such transfer, the Prepayment
Assumption and any required or permitted clean up calls or required qualified
liquidation provided for in the REMIC's organizational documents. Such a tax
would be generally imposed on the transferor of the REMIC Residual Certificate,
except that where such transfer is through an agent for a disqualified
organization, the tax would instead be imposed on such agent. However, a
transferor of a REMIC Residual Certificate would in no event be liable for such
tax with respect to a transfer if the transferee furnishes to the transferor an
affidavit that the transferee is not a disqualified organization, and, as of the
time of the transfer, the transferor did not have actual knowledge that such
affidavit was false. Moreover, an entity will not qualify as a REMIC unless
there are reasonable arrangements designed to ensure that (i) residual interests
in
 
                                       89
 

<PAGE>

<PAGE>
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 REMIC Residual Certificates and
certain other provisions that are intended to meet this requirement will be
included in the related Pooling and Servicing Agreement, and will be discussed
more fully in any Prospectus Supplement relating to the offering of any REMIC
Residual Certificate.
 
     In addition, if a 'pass-through entity' (as defined below) includes in
income excess inclusions with respect to a REMIC Residual Certificate and a
disqualified organization is the record holder of an interest in such entity,
then a tax will be imposed on such entity equal to the product of (i) the amount
of excess inclusions on the REMIC Residual Certificate that are allocable to the
interest in the pass-through entity held by such disqualified organization and
(ii) the highest marginal federal income tax rate imposed on corporations. A
pass-through entity will not be subject to this tax for any period, however, if
each record holder of an interest in such pass-through entity furnishes to such
pass-through entity (i) such holder's social security number and a statement
under penalty of perjury that such social security number is that of the record
holder or (ii) a statement under penalty of perjury that such record holder is
not a disqualified organization. For taxable years beginning after December 31,
1997, notwithstanding the preceding two sentences, in the case of a REMIC
Residual Certificate held by an 'electing large partnership,' all interests in
such partnership shall be treated as held by disqualified organizations (without
regard to whether the record holders of the partnership furnish statements
described in the preceding sentence) and the amount that would be subject to tax
under the second preceding sentence is excluded from the gross income of the
partnership (in lieu of a deduction in the amount of such tax generally allowed
to pass-through entities).
 
     For these purposes, a 'disqualified organization' means (i) the United
States, any State or political subdivision thereof, any foreign government, any
international organization, or any agency or instrumentality of the foregoing
(not including instrumentalities described in Section 168(h)(2)(D) of the Code
or the Federal Home Loan Mortgage Corporation), (ii) any organization (other
than a cooperative described in Section 521 of the Code) that is exempt from
federal income tax, unless it is subject to the tax imposed by Section 511 of
the Code or (iii) any organization described in Section 1381(a)(2)(C) of the
Code. For these purposes, a 'pass-through entity' means any regulated investment
company, real estate investment trust, trust, partnership or certain other
entities described in Section 860E(e)(6) of the Code. In addition, a person
holding an interest in a pass-through entity as a nominee for another person
will, with respect to such interest, be treated as a pass-through entity.
 
     Termination and Liquidation
 
     A REMIC will terminate immediately after the Distribution Date following
receipt by the REMIC of the final payment in respect of the Loans or upon a sale
of the REMIC's assets following the adoption by the REMIC of a plan of complete
liquidation. The last distribution on a REMIC Regular Certificate will be
treated as a payment in retirement of a debt instrument. In the case of a REMIC
Residual Certificate, if the last distribution on such REMIC Residual
Certificate is less than the REMIC Residual Certificateholder's adjusted basis
in such Certificate, such REMIC Residual Certificateholder should (but may not)
be treated as realizing a loss equal to the amount of such difference, and such
loss may be treated as a capital loss. If the REMIC adopts a plan of complete
liquidation, within the meaning of Section 860F(a)(4)(A)(i) of the Code, which
may be accomplished by designating in the REMIC's final tax return a date on
which such adoption is deemed to occur, and sells all of its assets (other than
cash) within a 90-day period beginning on such date, the REMIC will not be
subjected to any 'prohibited transactions taxes' solely on account of such
qualified liquidation, provided that the REMIC credits or distributes in
liquidation all of the sale proceeds plus its cash (other than the amounts
retained to meet claims) to holders of Regular and Residual Certificates within
the 90-day period.
 
     Reporting and Other Administrative Matters
 
     Solely for purposes of the administrative provisions of the Code, the REMIC
will be treated as a partnership and REMIC Residual Certificateholders will be
treated as partners. Unless otherwise stated in the related Prospectus
Supplement, the Trustee will file REMIC federal income tax returns on behalf of
the REMIC, will generally hold at least a nominal amount of REMIC Residual
Certificates, and will be designated as and will act as the 'tax matters person'
with respect to the REMIC in all respects.
 
                                       90
 

<PAGE>

<PAGE>
     The Trustee, as the tax matters person or as agent for the tax matters
person, subject to certain notice requirements and various restrictions and
limitations, generally will have the authority to act on behalf of the REMIC and
the REMIC Residual Certificateholders in connection with the administrative and
judicial review of items of income, deduction, gain or loss of the REMIC, as
well as the REMIC's classification. REMIC Residual Certificateholders will
generally be required to report such REMIC items consistently with their
treatment on the related REMIC's tax return and may in some circumstances be
bound by a settlement agreement between the Trustee, as the tax matters person
or as agent for the tax matters person, and the IRS concerning any such REMIC
item. Adjustments made to the REMIC tax return may require a REMIC Residual
Certificateholder to make corresponding adjustments on its return, and an audit
of the REMIC's tax return, or the adjustments resulting from such an audit,
could result in an audit of a REMIC Residual Certificateholder's return. Any
person that holds a REMIC Residual Certificate as a nominee for another person
may be required to furnish to the related REMIC, in a manner to be provided in
Treasury regulations, with the name and address of such person and other
information.
 
     Reporting of interest income, including any original issue discount, with
respect to REMIC Regular Certificates is required annually, and may be required
more frequently under Treasury regulations. These information reports generally
are required to be sent to certain trusts and individual holders of REMIC
Regular Interests and the IRS; holders of REMIC Regular Certificates that are
corporations, trusts described in Sections 664(c) and 4947(a)(1) of the Code,
securities dealers and certain other non-individuals will be provided interest
and original issue discount income information and the information set forth in
the following paragraph upon request in accordance with the requirements of the
applicable regulations. The information must be provided by the later of 30 days
after the end of the quarter for which the information was requested, or two
weeks after the receipt of the request. The REMIC must also comply with rules
requiring a REMIC Regular Certificate issued with original issue discount to
disclose on its face the amount of original issue discount and the issue date
among other things, and requiring such information to be reported to the IRS.
Reporting with respect to the REMIC Residual Certificates, including income,
excess inclusions, investment expenses and relevant information regarding
qualification of the REMIC's assets, will be made as required under the Treasury
regulations, generally on a quarterly basis.
 
     As applicable, the REMIC Regular Certificate information reports will
include a statement of the adjusted issue price of the REMIC Regular Certificate
at the beginning of each accrual period. In addition, the reports will include
information required by regulations with respect to computing the accrual of any
market discount. Because exact computation of the accrual of market discount on
a constant yield method would require information relating to the holder's
purchase price that the REMIC may not have, such regulations only require that
information pertaining to the appropriate proportionate method of accruing
market discount be provided. See ' -- Taxation of Owners of REMIC Regular
Certificates -- Market Discount.'
 
     The responsibility for complying with the foregoing reporting rules will be
borne by the Trustee.
 
     Backup Withholding With Respect to REMIC Certificates
 
     Payments of interest and principal, as well as payments of proceeds from
the sale of REMIC Certificates, may be subject to the 'backup withholding tax'
under Section 3406 of the Code at a rate of 31% if recipients of such payments
fail to furnish to the payor certain information, including their taxpayer
identification numbers, or otherwise fail to establish an exemption from such
tax. Treasury regulations (the 'Final Withholding Regulations'), which are
generally effective with respect to payments made after December 31, 1999,
consolidate and modify the current certification requirements and means by which
a holder may claim exemption from United States federal income tax withholding
and provide certain presumptions regarding the status of holders when payments
to the holders cannot be reliably associated with appropriate documentation
provided to the payor. All holders should consult their tax advisors regarding
the application of the Final Withholding Regulations. 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 payments that is required to supply
information but that does not do so in the proper manner.

     Foreign Investors in REMIC Certificates
 
     A REMIC Regular Certificateholder that is not a 'United States person' (as
defined below) and is not subject to federal income tax as a result of any
direct or indirect connection to the United States in addition to its ownership
of a REMIC Regular Certificate will not, unless otherwise disclosed in the
related Prospectus Supplement, be subject to United States federal income or
withholding tax in respect of a distribution on a REMIC Regular Certificate,
provided that the holder complies to the extent necessary with certain
identification requirements (including delivery of a statement, signed by the
Certificateholder under penalties of perjury, certifying that such
Certificateholder is not a United States person and providing the name and
address of such Certificateholder). The Final Withholding Regulations
consolidate and modify the current certification requirements and means by which
a non-United States person may claim exemption from United States federal income
tax withholding. All holders that are non-United States persons should consult
their tax advisors regarding the application of the Final Withholding
Regulations, which are generally effective with respect to payments made after
December 31, 1999. For these purposes, 'United States person' means a citizen or
resident of the United States, a corporation or partnership or entity treated as
a partnership or corporation for United States Federal income tax purposes
created or organized in, or under the laws of, the United States, any state
thereof or the District of Columbia (except, in the case of a partnership, to
the extent provided in regulations), an estate whose income is subject to United
States federal income tax regardless of its source, or a trust if a court within
the United States is able to exercise primary supervision over the
administration of the trust and one or more United States persons have the
authority to control all substantial decisions of the trust. To the extent
prescribed in regulations by the Secretary of the Treasury, which regulations
have not yet been issued, a trust which was in existence on August 20, 1996
(other than a trust treated as owned by the grantor under subpart E of part I of
subchapter J of chapter 1 of the Code), and which was treated as a United States
person on August 19, 1996, may elect to continue to be treated as a United
States person notwithstanding the previous sentence. It is possible that the IRS
may assert that the foregoing tax exemption should not apply with respect to a
REMIC Regular Certificate held by a REMIC Residual Certificateholder that owns
directly or indirectly a 10% or greater interest in the related REMIC Residual
Certificates. If the holder does not qualify for exemption, distributions of
interest, including distributions in respect of accrued original issue discount,
to such holder may be subject to a tax rate of 30%, subject to reduction under
any applicable tax treaty.
 
     In addition, the foregoing rules will not apply to exempt a United States
shareholder of a controlled foreign corporation from taxation on such United
States shareholder's allocable portion of the interest income received by such
controlled foreign corporation.
 
     Further, it appears that a REMIC Regular Certificate would not be included
in the estate of a non-resident alien individual and would not be subject to
United States estate taxes. However, Certificateholders who are non-resident
alien individuals should consult their tax advisors concerning this question.
Unless otherwise stated in the related Prospectus Supplement, transfers of REMIC
Residual Certificates to investors that are not United States persons will be
prohibited under the related Pooling and Servicing Agreement.
 
NOTES
 
     On or prior to the date of the related Prospectus Supplement with respect
to the proposed issuance of each Series of Notes, Counsel to the Depositor will
deliver its opinion to the effect that, assuming compliance with all provisions
of the Indenture, Owner Trust Agreement and certain related documents and upon
issuance of the Notes, for federal income tax purposes (i) the Notes will be
treated as indebtedness and (ii) the Issuer, as created pursuant to the terms
and conditions of the Owner Trust Agreement, will not be characterized as an
association (or publicly traded partnership) taxable as a corporation or as a
taxable mortgage pool.
 
     STATUS AS REAL PROPERTY LOANS
 
     Notes held by a domestic building and loan association will not constitute
'loans . . . secured by an interest in real property' within the meaning of Code
section 7701(a)(19)(C)(v); and (ii) Notes held by a real estate investment trust
will not constitute 'real estate assets' within the meaning of Code section
856(c)(4)(A) and interest on Notes will not be considered 'interest on
obligations secured by mortgages on real property' within the meaning of Code
section 856(c)(3)(B).

     Taxation of Noteholders
 
     Notes generally will be subject to the same rules of taxation as REMIC
Regular Certificates issued by a REMIC, as described above, except that (i)
income reportable on the Notes is not required to be reported under the accrual
method unless the holder otherwise uses the accrual method and (ii) the special
rule treating a portion of the gain on sale or exchange of a REMIC Regular
Certificate as ordinary income is inapplicable to the Notes. See
' -- REMICs -- Taxation of Owners of REMIC Regular Certificates' and ' -- Sales
of REMIC Certificates.'
 
                        STATE AND OTHER TAX CONSEQUENCES
 
     In addition to the federal income tax consequences described in 'Certain
Federal Income Tax Consequences,' potential investors should consider the state
and local tax consequences of the acquisition, ownership, and disposition of the
Securities offered hereunder. State tax law may differ substantially from the
corresponding federal tax law, and this discussion does not purport to describe
any aspect of the tax laws of any state or other jurisdiction. Therefore,
prospective investors should consult their own tax advisors with respect to the
various tax consequences of investments in the Securities offered hereunder.
 
                              ERISA CONSIDERATIONS
 
     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 similar 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';
Tax-Favored Plans and ERISA Plans, collectively, 'Plans').
 
     Certain employee benefit plans, such as governmental plans (as defined in
Section 3(32) of ERISA), and, if no election has been made under Section 410(d)
of the Code, church plans (as defined in Section 3(33) of ERISA), are not
subject to 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
transaction rules set forth in Section 503 of the Code.
 
     In addition to imposing 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, Section
406 of ERISA and Section 4975 of the Code prohibit a broad range of transactions
involving 'Plan Assets' of Plans and persons ('parties in interest' under
Section 3(14) of ERISA or 'disqualified persons' under Section 4975(e)(2) of the
Code; collectively, 'Parties In Interest') who have certain specified
relationships to the Plans, unless a statutory, regulatory or administrative
exemption is available. Certain Parties in Interest 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, regulatory or administrative exemption is available.
 
     Plan Asset Regulations. Certain transactions involving a Trust Fund might
be deemed to constitute prohibited transactions under ERISA and the Code with
respect to a Plan that purchases the Securities, if the underlying Mortgage
Assets and other assets included in the Trust Fund are deemed to be assets of
the Plan. The U.S. Department of Labor (the 'DOL') has promulgated regulations
at 29 C.F.R. 'SS'2510.3-101 (the 'Plan Asset Regulations') defining the term
'Plan Assets' for purposes of applying the general fiduciary responsibility
provisions of ERISA and the prohibited transaction provisions of ERISA and the
Code. Under the Plan Asset Regulations, generally, when a Plan acquires an
'equity interest' in another entity (such as the Trust Fund), the underlying
assets of that entity may be considered to be Plan Assets unless certain
exceptions apply. In addition to several exceptions not applicable to an entity
like the Trust Fund, a Plan's Assets will not include an undivided interest in
each asset of an entity in which such Plan makes an equity investment if Benefit
Plan Investors (i.e., Plans and certain employee benefit plans not subject to
ERISA) do not own 25% or more in value of any class of equity securities issued
by the entity. Neither Plans nor persons investing Plan Assets should acquire or
hold Securities in reliance upon the availability of any exception under the
Plan Asset Regulations. The Plan Asset Regulations provide that the term 'equity
interest' means any interest in an entity other than an
 
                                       93
 

<PAGE>

<PAGE>
instrument which is treated as indebtedness under applicable local law and which
has no 'substantial equity features.' Under the Plan Asset Regulations, Plan
Assets will be deemed to include an interest in the instrument evidencing the
equity interest of a Plan (such as a Certificate or a Note with 'substantial
equity features'), and, because of the factual nature of certain of the rules
set forth in the Plan Asset Regulations, Plan Assets may be deemed to include an
interest in the underlying assets of the entity in which a Plan acquires an
interest (such as the Trust Fund). Without regard to whether the Notes are
characterized as equity interests, the purchase, sale and holding of Notes by or
on behalf of a Plan could be considered to give rise to a prohibited transaction
if the Issuer, the applicable Trustee or any of their respective affiliates is
or becomes a Party in Interest with respect to such Plan.
 
     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, is a fiduciary of the investing
Plan. If the Mortgage Assets and other assets included in a Trust Fund
constitute Plan Assets, then any party exercising management or discretionary
control regarding those assets, such as the Master Servicer, any Servicer, any
sub-servicer, the Trustee, the obligor under any credit enhancement mechanism,
or certain affiliates thereof may be deemed to be a Plan 'fiduciary' and thus
subject to the fiduciary responsibility provisions and prohibited transaction
provisions of ERISA and the Code with respect to the investing Plan. In
addition, if the Mortgage Assets and other assets included in a Trust Fund
constitute Plan Assets, the purchase of Certificates by a Plan, as well as the
operation of the Trust Fund, may constitute or involve a prohibited transaction
under ERISA or the Code.
 
     The Plan Asset Regulations provide that where a Plan acquires a 'guaranteed
governmental mortgage pool certificate', the Plan's assets include such
certificate but do not solely by reason of the Plan's holdings of such
certificate include any of the mortgages underlying such certificate. The Plan
Asset Regulations include in the definition of a 'guaranteed governmental
mortgage pool certificate' FHLMC Certificates, GNMA Certificates and FNMA
Certificates. Accordingly, even if such Agency Securities included in a Trust
Fund were deemed to be assets of Plan investors, the mortgages underlying such
Agency Securities would not be treated as assets of such Plans. Private Mortgage
Backed Securities are not 'guaranteed governmental mortgage pool certificates'
within the meaning of the Plan Asset Regulations. Potential Plan investors
should consult their counsel and review the ERISA discussion herein and in the
related Prospectus Supplement before purchasing any such Certificates.
 
     Prohibited Transaction Exemption. The DOL has granted to Donaldson, Lufkin
& Jenrette Securities Corporation ('DLJ') an individual prohibited transaction
exemption, as amended (Prohibited Transaction Exemption 90-83, the 'Exemption'),
which generally exempts from the application of the prohibited transaction
provisions of Section 406 of ERISA, and the excise taxes imposed on such
prohibited transactions pursuant to Section 4975(a) and (b) of the Code, certain
transactions, among others, relating to the servicing and operation of mortgage
pools and the purchase, sale, holding and disposition of mortgage pass-through
securities underwritten by an Underwriter (as hereinafter defined), provided
that certain conditions set forth in the Exemption are satisfied. For purposes
of this Section 'ERISA Considerations,' the term 'Underwriter' includes (a) DLJ,
(b) any person directly or indirectly, through one or more intermediaries,
controlling, controlled by or under common control with DLJ and (c) any member
of the underwriting syndicate or selling group of which a person described in
(a) or (b) is a manager or co-manager with respect to a class of Securities.
'Securities' potentially covered by the Exemptions would include Certificates,
Notes that are treated as 'equity interests' under the Plan Assets Regulation,
and interests issued by a Trust Fund that elects to be treated as a REMIC or
FASIT.
 
     The Exemption sets forth six general conditions which must be satisfied for
a transaction involving the purchase, sale and holding of Securities to be
eligible for exemptive relief thereunder. First, the acquisition of Securities
by a Plan or with Plan Assets must be on terms that are at least as favorable to
the Plan as they would be in an arm's-length transaction with an unrelated
party. Second, the Exemption only applies to Securities evidencing rights and
interests that are not subordinated to the rights and interests evidenced by the
other Securities of the same Trust Fund. Third, the Securities at the time of
acquisition by or with Plan Assets must be rated in one of the three highest
generic rating categories by Standard and Poor's, a Division of the McGraw-Hill
Companies, Inc., Moody's Investors Service, Inc., Duff & Phelps, Inc. or Fitch
IBCA, Inc. (collectively, the 'Exemption Rating Agencies'). Fourth, the Trustee
cannot be an affiliate of any other member of the 'Restricted Group,' which
consists of any Underwriter, the Master Servicer, any Servicer, any subservicer,
the
 
                                       94
 

<PAGE>

<PAGE>
Trustee and any obligor with respect to assets of a Trust Fund constituting more
than 5% of the aggregate unamortized principal balance of the assets in the
Trust Fund as of the date of initial issuance of the Securities. Fifth, the sum
of all payments made to and retained by the Underwriters must represent not more
than reasonable compensation for underwriting the Securities; the sum of all
payments made to and retained by the Depositor pursuant to the assignment of the
assets to the related Trust Fund must represent not more than the fair market
value of such obligations, and the sum of all payments made to and retained by
the Master Servicer, any Servicer and any subservicer must represent not more
than reasonable compensation for such person's services under the related
Agreement and reimbursement of such person's reasonable expenses in connection
therewith. Sixth, the Exemption requires that the investing Plan be an
accredited investor as defined in Rule 501(a)(1) of Regulation D of the
Securities and Exchange Commission under the Securities Act of 1933, as amended.
 
     The Exemption also requires that a Trust Fund meet the following
requirements: (i) the Trust Fund must consist solely of assets of a type that
have been included in other investment pools; (ii) securities in such other
investment pools must have been rated in one of the three highest categories of
one of the Exemption Rating Agencies for at least one year prior to the Plan's
acquisition of Securities; and (iii) securities in such other investment pools
must have been purchased by investors other than Plans for at least one year
prior to any Plan's acquisition of Securities.
 
     A fiduciary of any Plan or other investor of Plan Assets contemplating
purchasing a Certificate or Note must make its own determination that the
general conditions set forth above will be satisfied with respect to such
Certificate or Note.
 
     If the general conditions of the Exemption are satisfied, the Exemption may
provide an exemption from the restrictions imposed by Sections 406(a) and 407 of
ERISA (as well as the excise taxes imposed by Sections 4975(a) and (b) of the
Code by reason of Sections 4975(c)(1)(A) through (D) of the Code) in connection
with the direct or indirect sale, exchange, transfer, holding, acquisition or
disposition in the secondary market of Securities by Plans or with Plan Assets.
However, no exemption is provided from the restrictions of Sections 406(a)(1)(E)
and 406(a)(2) of ERISA in connection with the direct or indirect sale, exchange,
transfer, holding, acquisition or disposition of a Certificate or Note by, or
with Plan Assets of, an 'Excluded Plan' (as hereinafter defined) by any person
who has discretionary authority or renders investment advice with respect to
Plan Assets of such Excluded Plan. For purposes of the Securities, an Excluded
Plan is a Plan sponsored by any member of the Restricted Group.
 
     If certain specific conditions of the Exemption are also satisfied, the
Exemption may provide an exemption from the restrictions imposed by Sections
406(b)(1) and (b)(2) of ERISA and the taxes imposed by Section 4975(c)(1)(E) of
the Code in connection with (i) the direct or indirect sale, exchange or
transfer of Securities in the initial issuance of Securities between the Company
or an Underwriter and a Plan when the person who has discretionary authority or
renders investment advice with respect to the investment of the relevant Plan
Assets in the Securities is (a) a mortgagor with respect to 5% or less of the
fair market value of the assets of the related Trust Fund or (b) an affiliate of
such a person, (ii) the direct or indirect acquisition or disposition of
Securities in the secondary market by a Plan or an entity investing Plan Assets
and (iii) the holding of Securities by a Plan or an Entity investing Plan
Assets.
 
     Further, if certain specific conditions of the Exemption are satisfied, the
Exemption may provide an exemption from the restrictions imposed by Sections
406(a), 406(b) and 407(a) of ERISA, and the taxes imposed by Sections 4975(a)
and (b) of the Code by reason of Section 4975(c) of the Code for transactions in
connection with the servicing, management and operation of the Trust Funds. The
Depositor expects that the specific conditions of the Exemption required for
this purpose will be satisfied with respect to the Securities so that the
Exemption would provide an exemption from the restrictions imposed by Sections
406(a) and (b) and 407(a) of ERISA (as well as the excise taxes imposed by
Sections 4975(a) and (b) of the Code by reason of Section 4975(c) of the Code)
for transactions in connection with the servicing, management and operation of
the Trust Funds, provided that the general conditions of the Exemption are
satisfied.
 
     The Exemption also may provide an exemption from the restrictions imposed
by Sections 406(a) and 407(a) of ERISA, and the taxes imposed by Section 4975(a)
and (b) of the Code by reason of Sections 4975(c)(1)(A) through (D) of the Code
if such restrictions would to otherwise apply merely because a person is deemed
to be a Party In Interest with respect to an investing Plan (or the investing
entity holding Plan Assets) by
 
                                       95

<PAGE>
virtue of providing services to the Plan (or by virtue of having certain
specified relationships to such a person) solely as a result of the ownership of
Securities by a Plan or the investment of Plan Assets in Securities.
 
     On July 21, 1997, the DOL amended the Exemption to extend exemptive relief
to certain mortgage-backed and asset-backed securities transactions using
Funding Accounts for trusts issuing pass-through certificates. With respect to
the Securities, the amendment generally allows Mortgage Loans supporting
payments to Securityholders, and having a value equal to no more than 25% of the
total principal amount of the Securities being offered by a Trust Fund, to be
transferred to such Trust Fund within a period no longer than 90 days or three
months following the Closing Date ('Pre-Funding Period') instead of requiring
that all such Mortgage Loans be either identified or transferred on or before
the Closing Date. In general, the relief applies to the purchase, sale and
holding of Securities which otherwise qualify for the Exemption, provided that
the following general conditions are met:
 
          (1) the ratio of the amount allocated to the Funding Account to the
     total principal amount of the Securities being offered ('Pre-Funding
     Limit') must be less than or equal to 25%;
 
          (2) all additional Mortgage Loans transferred to the related Trust
     Fund after the Closing Date ('Subsequent Mortgage Loans') must meet the
     same terms and conditions for eligibility as the original Mortgage Loans
     used to create the Trust Fund, which terms and conditions have been
     approved by one of the Exemption Rating Agencies;
 
          (3) the transfer of such Subsequent Mortgage Loans to the Trust Fund
     during the Pre-Funding Period must not result in the Securities to be
     covered by the Exemption receiving a lower credit rating from an Exemption
     Rating Agency upon termination of the Pre-Funding Period than the rating
     that was obtained at the time of the initial issuance of the Securities by
     the Trust Fund;
 
          (4) solely as a result of the use of pre-funding, the weighted average
     annual percentage interest rate (the 'Average Interest Rate') for all of
     the Mortgage Loans and Subsequent Mortgage Loans in the Trust Fund at the
     end of the Pre-Funding Period must not be more than 100 basis points lower
     than the Average Interest Rate for the Mortgage Loans which were
     transferred to the Trust Fund on the Closing Date;
 
          (5) in order to ensure that the characteristics of the Subsequent
     Mortgage Loans are substantially similar to those of the Original Mortgage
     Loans:
 
             (i) the characteristics of the Subsequent Mortgage Loans must be
        monitored by an insurer or other credit support provider which is
        independent of the Depositor; or
 
             (ii) an independent accountant retained by the Depositor must
        provide the Depositor with a letter (with copies provided to the
        Exemption Rating Agency rating the Securities, the Underwriter and the
        Trustee) stating whether or not the characteristics of the Subsequent
        Mortgage Loans conform to the characteristics described in the
        Prospectus or Prospectus Supplement and/or Agreement. In preparing such
        letter, the independent accountant must use the same type of procedures
        as were applicable to the Mortgage Loans which were transferred to the
        Trust Fund as of the Closing Date;
 
          (6) the Pre-Funding Period must end no later than three months or 90
     days after the Closing Date or earlier in certain circumstances if the
     Funding Accounts falls below the minimum level specified in the Agreement
     or an event of default occurs;
 
          (7) amounts transferred to any Funding Accounts and/or capitalized
     interest accounts used in connection with the pre-funding may be invested
     only in certain permitted investments;
 
          (8) the Prospectus or Prospectus Supplement must describe the duration
     of the Pre-Funding Period; and
 
          (9) the Trustee (or any agent with which the Trustee contracts to
     provide trust services) must be a substantial financial institution or
     trust company experienced in trust activities and familiar with its duties,
     responsibilities and liabilities as a fiduciary under ERISA. The Trustee,
     as legal owner of the Trust Fund, must enforce all the rights created in
     favor of Securityholders of the Trust Fund, including employee benefit
     plans subject to ERISA.
 
     Before purchasing a Certificate or Note, a fiduciary of a Plan or other
investor of Plan Assets should itself confirm (a) that the Securities constitute
'certificates' for purposes of the Exemption and (b) that the specific and
general conditions set forth in the Exemption and the other requirements set
forth in the Exemption would
 
                                       96
 

<PAGE>

<PAGE>
be satisfied. In addition to making its own determination as to the availability
of the exemptive relief provided in the Exemption, the fiduciary or other Plan
investor should consider its general fiduciary obligations under ERISA in
determining whether to purchase any Securities by or with Plan Assets.
 
     Any fiduciary or other Plan investor which proposes to purchase Securities
on behalf of or with Plan Assets should consult with its counsel with respect to
the potential applicability of ERISA and the Code to such investment and the
availability of the Exemption or any other prohibited transaction exemption in
connection therewith. In particular, in connection with a contemplated purchase
of Securities representing a beneficial ownership interest in a pool of
single-family residential first mortgage loans, such fiduciary or other Plan
investor should consider the availability of the Exemption or Prohibited
Transaction Class Exemption ('PTCE') 83-1 ('PTCE 83-1') for certain transactions
involving mortgage pool investment trusts. However, PTCE 83-1 does not provide
exemptive relief with respect to Securities evidencing interests in Trust Funds
which include Cooperative Loans and may not provide exemptive relief for
Securities having certain cash-flow characteristics that may be issued by a
Trust Fund. In addition, such fiduciary or other Plan investor should consider
the availability of PTCE 96-23, regarding transactions effected by 'in-house
asset managers', PTCE 95-60, regarding investments by insurance company general
accounts, PTCE 90-1, regarding investments by insurance company pooled separate
accounts, PTCE 91-38, regarding investments by bank collective investment funds,
and PTCE 84-14, regarding transactions effected by 'qualified professional asset
managers.' The Prospectus Supplement with respect to a Series of Securities may
contain additional information regarding the application of the Exemption, PTCE
83-1, or any other exemption, with respect to the Securities offered thereby.
There can be no assurance that any of these exemptions will apply with respect
to any particular Plan's or other Plan investor's investment in the Securities
or, even if an exemption were deemed to apply, that any exemption would apply to
all prohibited transactions that may occur in connection with such investment.
 
     In addition to any exemption that may be available under PTCE 95-60 for the
purchase and holding of the Securities by an insurance company general account,
the Small Business Job Protection Act of 1996 added a new Section 401(c) to
ERISA, which provides certain exemptive relief from the provisions of Part 4 of
Title I of ERISA and Section 4975 of the Code, including the prohibited
transaction restrictions imposed by ERISA and the related excise taxes imposed
by the Code, for transactions involving an insurance company general account.
Pursuant to Section 401(c) of ERISA, the DOL published proposed regulations
('Proposed 401(c) Regulations') on December 22, 1997; however the required final
regulations have not been issued as of the date hereof. The Proposed 401(c)
Regulations provide guidance for the purpose of determining, in cases where
insurance policies supported by an insurer's general account are issued to or
for the benefit of a Plan on or before December 31, 1998, which general account
assets constitute Plan Assets. Section 401(c) of ERISA generally provides that,
until the date which is 18 months after the Proposed 401(c) Regulations become
final, no person shall be subject to liability under Part 4 of Title I of ERISA
and Section 4975 of the Code on the basis of a claim that the assets of an
insurance company general account constitute Plan Assets, unless (i) as
otherwise provided by the Secretary of Labor in the Proposed 401(c) Regulations
to prevent avoidance of the regulations or (ii) an action is brought by the
Secretary of Labor for certain breaches of fiduciary duty which would also
constitute a violation of federal or state criminal law. Any assets of an
insurance company general account which support insurance policies issued to a
Plan after December 31, 1998 or issued to Plans on or before December 31, 1998
for which the insurance company does not comply with the Proposed 401(c)
Regulations may be treated as Plan Assets. In addition, because Section 401(c)
does not relate to insurance company separate accounts, separate account assets
are still treated as Plan Assets of any Plan invested in such separate account.
Insurance companies contemplating the investment of general account assets in
the Securities should consult with their legal counsel with respect to the
applicability of Section 401(c) of ERISA, including the general account's
ability to continue to hold the Securities after the date which is 18 months
after the date the Proposed 401(c) Regulations become final.
 
     Representations from Plans Investing in Notes with 'Substantial Equity
Features' or in Certain Securities. Because the exemptive relief afforded by the
Exemption (or any similar exemption that might be available) will not apply to
the purchase, sale or holding of certain Securities, such as Notes with
'substantial equity features,' Subordinate Securities, REMIC Residual
Certificates, any Securities which are not rated in one of the three highest
generic rating categories by the Exemption Rating Agencies, transfers of any
such Securities to a Plan, to a trustee or other person acting on behalf of any
Plan, or to any other person investing Plan Assets to effect such acquisition
will not be registered by the Trustee unless the transferee provides the
Depositor, the Trustee and the Master Servicer with an opinion of counsel
satisfactory to the Depositor, the Trustee and the Master Servicer, which
opinion will not be at the expense of the Depositor, the Trustee or the Master
Servicer, that the
 
                                       97
 

<PAGE>

<PAGE>
purchase of such Securities by or on behalf of such Plan is permissible under
applicable law, will not constitute or result in any non-exempt prohibited
transaction under ERISA or Section 4975 of the Code and will not subject the
Depositor, the Trustee or the Master Servicer to any obligation in addition to
those undertaken in the related Agreement.
 
     In lieu of such opinion of counsel, the transferee may provide a
certification substantially to the effect that the purchase of Securities by or
on behalf of such Plan is permissible under applicable law, will not constitute
or result in any non-exempt prohibited transaction under ERISA or Section 4975
of the Code and will not subject the Depositor, the Trustee or the Master
Servicer to any obligation in addition to those undertaken in the Agreement and
that the following statements are correct: (i) the transferee is an insurance
company; (ii) the source of funds used to purchase such Securities is an
'insurance company general account' (as such term is defined in PTCE 95-60);
(iii) the conditions set forth in Sections I and III of PTCE 95-60 have been
satisfied; and (iv) there is no Plan with respect to which the amount of such
general account's reserves and liabilities for contracts held by or on behalf of
such Plan and all other Plans maintained by the same employer (or any
'affiliate' thereof, as defined in PTCE 95-60) or by the same employee
organization exceed 10% of the total of all reserves and liabilities of such
general account (as determined under PTCE 95-60) as of the date of the
acquisition of such Securities.
 
     An opinion of counsel or certification will not be required with respect to
the purchase of Securities registered through DTC. Any purchaser of a Security
registered through DTC will be deemed to have represented by such purchase that
either (a) such purchaser is not a Plan and is not purchasing such Securities on
behalf of, or with Plan Assets of, any Plan or (b) the purchase of any such
Security by or on behalf of, or with Plan Assets of, any Plan is permissible
under applicable law, will not result in any non-exempt prohibited transaction
under ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the related Agreement.
 
     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' ('UBTI') within the meaning of Section 512
of the Code. All 'excess inclusions' of a REMIC allocated to a REMIC Residual
Certificate held by a Tax-Exempt Investor will be considered UBTI and thus will
be subject to federal income tax. See 'Certain Federal Income Tax
Consequences -- Taxation of Owners of REMIC Residual Certificates -- Excess
Inclusions.'
 
     Consultation With Counsel. Any fiduciary of a Plan or other Plan investor
that proposes to acquire or hold Securities on behalf of a Plan or with Plan
Assets 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 the Exemption, PTCE 83-1 or any other
prohibited transaction exemption.
 
                                LEGAL INVESTMENT
 
     Each class of Securities offered hereby and by the related Prospectus
Supplement will be rated at the date of issuance in one of the four highest
rating categories by at least one Rating Agency. Unless otherwise set forth in
the related Prospectus Supplement, Securities of any Series will constitute
'mortgage related securities' for purposes of the Secondary Mortgage Market
Enhancement Act of 1984 ('SMMEA') so long as they are rated by a Rating Agency
in one of its two highest categories and, as such, will be legal investments for
persons, trusts, corporations, partnerships, associations, business trusts and
business entities (including, but not limited to, state-chartered savings banks,
commercial banks, savings and loan associations and insurance companies, as well
as trustees and state government employee retirement systems) created pursuant
to or existing under the laws of the United States or of any State (including
the District of Columbia and Puerto Rico) whose authorized investments are
subject to State 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. Any Class of Securities that represents an interest in a Trust
Fund that includes junior mortgage loans will not constitute 'mortgage related
securities' for purposes of SMMEA.
 
     Under SMMEA, if a State enacted legislation prior to October 4, 1991
specifically limiting the legal investment authority of any such entities with
respect to 'mortgage related securities,' the Securities will constitute legal
investments for entities subject to such legislation only to the extent provided
in such legislation.
 
                                       98
 

<PAGE>

<PAGE>
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 limitations as to the percentage of their
assets represented thereby; federal credit unions may invest in mortgage-related
securities, and national banks may purchase mortgage-related 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 Institution 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 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 the Securities of any Series will be
treated as high-risk under the Policy Statement.
 
     The predecessor to the OTS issued a bulletin, entitled, 'Mortgage
Derivative Products and Mortgage Swaps,' which is applicable to thrift
institutions regulated by the OTS. The bulletin established guidelines for the
investment by savings institutions in certain 'high-risk' mortgage derivative
securities and limitations on the use of such securities by insolvent,
undercapitalized or otherwise 'troubled' institutions. According to the
bulletin, such 'high-risk' mortgage derivative securities include securities
having certain specified characteristics, which may include certain classes of
Securities. 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.
 
     Certain classes of Securities offered hereby, including any class that is
not rated in one of the two highest categories by at least one Rating Agency,
will not constitute 'mortgage related securities' for purposes of SMMEA. Any
such class of Securities will be identified in the related Prospectus
Supplement. Prospective investors in such classes of Securities, in particular,
should consider the matters discussed in the following paragraph.
 
     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

     Certain legal matters in connection with the Securities offered hereby will
be passed upon for the Depositor and for the Underwriters by Thacher Proffitt &
Wood, New York, New York, Brown and Wood LLP, New York, New York or Stroock &
Stroock & Lavan LLP, New York, New York.
 
                                 THE DEPOSITOR
 
     The Depositor was incorporated in the State of Delaware on April 14, 1988
and is a wholly-owned subsidiary of Donaldson, Lufkin & Jenrette Inc., a
Delaware corporation. The principal executive offices of the Depositor are
located at 277 Park Avenue, 9th Floor, New York, New York 10172. Its telephone
number is (212) 892-3000.
 
     The Depositor was organized, among other things, for the purposes of
establishing trusts, selling beneficial interests therein and acquiring and
selling mortgage assets to such trusts. The Depositor has one class of common
stock, all of which is owned by Donaldson, Lufkin & Jenrette Inc.
 
     Neither the Depositor, its parent nor any of the Depositor's affiliates
will ensure or guarantee distributions on the Securities of any Series.
 
     As described herein, the only obligations of the Depositor will be pursuant
to certain representations and warranties with respect to the Mortgage Assets.
See 'Loan Underwriting Standards -- Representations and Warranties' and 'The
Agreements -- Assignment of Mortgage Assets' herein. The Depositor will have no
ongoing servicing responsibilities or other responsibilities with respect to any
Mortgage Asset. The Depositor does not have nor is it expected in the future to
have any significant assets with which to meet any obligations with respect to
any Trust Fund. If the Depositor were required to repurchase or substitute a
Loan, its only source of funds to make the required payment would be funds
obtained from the Seller of such Loan, or if applicable, the Master Servicer or,
the Servicer. See 'Risk Factors' herein.
 
                                USE OF PROCEEDS
 
     The Depositor will apply all or substantially all of the net proceeds from
the sale of each Series offered hereby and by the related Prospectus Supplement
to purchase the Mortgage Assets, to repay indebtedness which has been incurred
to obtain funds to acquire the Mortgage Assets, to establish the reserve funds,
if any, for the Series and to pay costs of structuring, guaranteeing and issuing
the Securities. If so specified in the related Prospectus Supplement, Securities
may be exchanged by the Depositor for Mortgage Assets. The Depositor 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 Depositor, prevailing interest rates, availability of funds and
general market conditions.
 
                              PLAN OF DISTRIBUTION
 
     The Securities offered hereby and by the related Prospectus Supplements
will be offered in Series may be sold directly by the Depositor or may be
offered through Donaldson, Lufkin & Jenrette Securities Corporation, an
affiliate of the Depositor, or through underwriting syndicates represented by
Donaldson, Lufkin & Jenrette Securities Corporation (the 'Underwriters') through
one or more of the methods described below. The Prospectus Supplement prepared
for each Series will describe the method of offering being utilized for that
Series and will state the net proceeds to the Depositor from such sale.
 
     The Depositor 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 the Underwriters;
 
          2. by placements by the Depositor with institutional investors through
     dealers; and
 
          3. by direct placements by the Depositor 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 Loans (and
other assets, if applicable) that would comprise the Trust Fund for such

     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 varying prices to be determined at the time
of sale or at the time of commitment therefor. 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, the Underwriters may receive
compensation from the Depositor 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 Depositor 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.
 
     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 Depositor will indemnify the several Underwriters and the
Underwriters will indemnify the Depositor 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 Depositor and purchasers of
Securities of such Series.
 
     The Depositor anticipates that the Securities offered hereby will be sold
primarily to institutional investors or sophisticated non-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.
