(2) On certain distribution dates, as described under 'Description of the
    Certificates -- Distributions' in this prospectus supplement, the
    pass-through rate of the Class AF certificates will be lower than the rate

OPTIONAL TERMINATION
 
    The Master Servicer will have the option to purchase the assets of the trust
    on any distribution date on which the principal balance of the mortgage
    loans and any real estate owned by the trust as of such date is less than
    10% of the principal balance of the mortgage loans on  March 1, 1999.
 
    If the trust includes properties previously acquired on behalf of the trust,
    then the proceeds from the exercise of the right to optional termination
    may be insufficient to pay certificateholders what they would otherwise be
    entitled to be paid.

CONSIDER CAREFULLY THE RISK FACTORS BEGINNING ON PAGE S-8 IN THIS PROSPECTUS
SUPPLEMENT AND ON PAGE 14 IN THE PROSPECTUS.

The certificates represent obligations of the trust only and do not represent
an interest in or obligation of IndyMac ABS, Inc., IndyMac, Inc. or any of
their affiliates.

This prospectus supplement may be used to offer and sell the offered
certificates only if accompanied by the prospectus.
 
NEITHER THE SEC NOR ANY STATE SECURITIES COMMISSION HAS APPROVED THESE
SECURITIES OR DETERMINED THAT THIS PROSPECTUS SUPPLEMENT OR THE PROSPECTUS IS
ACCURATE OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
     NationsBanc Montgomery Securities LLC and PaineWebber Incorporated, as
underwriters, will purchase the offered certificates from the depositor. Each
underwriter will offer the certificates it purchases from time to time in
negotiated transactions or otherwise at varying prices to be determined at the
time of sale. We expect the proceeds to the depositor from the sale of the
offered certificates to be approximately 99.98% of the aggregate principal
balance of the offered certificates, not including accrued interest and before
deducting issuance expenses payable by the depositor. See 'Method of
Distribution' in this prospectus supplement.
 
     We expect the offered certificates, other than the Class R certificates,
will be ready for delivery in book-entry form only through the facilities of The
Depository Trust Company. We similarly expect that the Class R certificates will
be ready for delivery at the offices of NationsBanc Montgomery Securities LLC in
Charlotte, North Carolina on or about March 30, 1999.

DISTRIBUTION DATES
 
The trustee will make distributions on the 25th day of each calendar month
beginning in April 1999 to the holders of record of the certificates as of the
last business day of the month preceding the distributions. If the 25th day of a
month is not a business day, then the distributions will be made on the next
business day after the 25th day of the month.
 
INTEREST PAYMENTS
 
The interest rate for each class of offered certificates is specified on the
cover page of this prospectus supplement. Interest will accrue on the fixed rate
certificates on the basis of a 360-day year divided into twelve 30 day months.
Interest will accrue on the adjustable rate certificates on the basis of a
360-day year and the actual number of days elapsed in the applicable Interest
Accrual Period. The 'Interest Accrual Period' for the fixed rate certificates
for any distribution date will be the calendar month preceding the month of such
distribution date. The 'Interest Accrual Period' for the adjustable rate
certificates for any distribution date will be the period from and including the
preceding distribution date (or, in the case of the first distribution date, the
closing date) to and including the day prior to such next distribution date.
 
PRINCIPAL PAYMENTS
 
Principal will be paid on the certificates on the 25th day of each month as
described under 'Description of the Certificates -- Distributions' in this
prospectus supplement.
 
MORTGAGE LOANS
The aggregate principal balance of the mortgage loans in the trust fund as of
March 1, 1999 is approximately $193,539,716.66. The mortgage loans will be
divided into two separate groups, which are referred to as a 'loan group',
individually, 'loan groups' in the aggregate, 'loan group 1', 'loan group 2',
'group 1 mortgage loans' or 'group 2 mortgage loans' in this prospectus
supplement.
 
Loan group 1 consists solely of fixed rate mortgage loans that are secured by
first and second liens on mortgaged properties. Loan group 2 consists of
adjustable rate mortgage loans that are secured by first liens on mortgaged
properties.
 
As described in this prospectus supplement under 'The Mortgage Pool', the
interest rates for the adjustable rate mortgage loans will generally adjust
semi-annually or annually, subject to certain caps and floors, as described
herein.
 
Approximately 85.02% of the loan group 2 mortgage loans are mortgage loans that
initially have a fixed rate of interest for two or more years following their
origination, and thereafter have an adjustable rate of interest for the
remaining life of the mortgage loan, as described under 'The Mortgage Pool' in
this prospectus supplement.
 
See 'The Mortgage Pool' in this prospectus supplement.
 
OPTIONAL TERMINATION
 
The Master Servicer may purchase all of the remaining assets of the trust after
the principal balance of the mortgage loans and any real estate owned by the
trust declines below 10% of the principal balance of the mortgage loans on
March 1, 1999.
 
See 'Description of the Certificates -- Optional Termination' in this prospectus
supplement.
 
ADVANCES
 
The Master Servicer will make cash advances with respect to delinquent payments
of principal and interest on the mortgage loans unless the Master Servicer
reasonably believes that the cash advances cannot be repaid from future payments
on the mortgage loans. These cash advances are only intended to maintain a
regular flow of scheduled interest and principal payments on the

                                   S-5

 <PAGE>
<PAGE>

certificates and are not intended to guarantee or insure against losses.
 
See 'Servicing of Mortgage Loans -- Advances 'in this prospectus supplement.
 
CREDIT ENHANCEMENT
 
Credit enhancements provide limited protection to certain holders of
certificates against shortfalls in payments received on the mortgage loans. This
transaction employs the following forms of credit enhancement.
 
Policy
 
The policy will irrevocably and unconditionally guarantee, on each distribution
date with respect to the Class AF and Class AV Certificates and the first
distribution date with respect to the Class R Certificates, to the trustee for
the benefit of the certificateholders the full and complete payment of the
guaranteed distributions consisting of
 
 the guaranteed principal distribution amount with respect to the certificates
 for such distribution date and
 
 accrued and unpaid interest due on the certificates.
 
The effect of the policy is to guarantee the timely payment of interest on, and
the ultimate payment of the principal amount of, the certificates.
In addition, the policy will guarantee the payment of the outstanding
certificate principal balance on the distribution date in April 2029 (after
giving effect to all other amounts distributable and allocable to principal on
that distribution date).
 
The policy does not cover any distributions of interest or principal after the
first distribution date with respect to the Class R Certificates.
 
In the absence of payments under the policy, certificateholders will directly
bear the credit and other risks associated with their percentage interest in the
trust fund.
 
See 'Description of the Certificates -- The Policy' in this prospectus
supplement.
 
Overcollateralization
 
The mortgage loans are expected to generate more interest than is needed to pay
interest on the offered certificates because the weighted average interest rate
of the mortgage loans is expected to be higher than the weighted average
pass-through rate on the offered certificates. Any interest payments received in
respect of the mortgage loans in excess of the amount that is needed to pay
interest on the offered certificates will be used to reduce the total principal
balance of such certificates.

When excess interest payments received in respect of the mortgage loans are used
to reduce principal owed on the certificates, the aggregate principal balance of
the mortgage loans may become greater than the principal balance of such
certificates. If this occurs, the certificates will be 'overcollateralized,' and
on any distribution date, the amount of any such overcollateralization will be
available to absorb losses from liquidated mortgage loans. The use of excess
interest will continue until a required level of overcollateralization is
reached at which time it will stop unless it is necessary to again reach or
maintain the required level.
 
See 'Description of the Certificates -- Overcollateralization Provisions' in
this prospectus supplement.
 
RATINGS
 
The classes of certificates listed below will not be offered unless they are
assigned the following ratings by Moody's Investors Services, Inc. ('Moody's')
and by Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ('S&P').

</TABLE>
 
See 'Ratings' in this prospectus supplement.
 
TAX STATUS
 
For federal income tax purposes, the trust will comprise multiple real estate
mortgage investment conduits. One REMIC, the Initial Subsidiary REMIC, will hold
the mortgage loans and will issue several classes of uncertificated interests
that will be designated as regular and residual interests. The Initial
Subsidiary REMIC will be part of a tiered REMIC structure in which the regular
interests issued by one REMIC will constitute assets of a higher tier REMIC. The
offered certificates (other than the Class R Certificates) and the Class PF,
Class PV and Class OC Certificates will represent the regular interests in the
Master REMIC. The Class R Certificates will represent ownership of the residual
interest in each of the REMICs.
 
See 'Material Federal Income Tax Consequences' in this prospectus supplement and
in the prospectus.

ERISA CONSIDERATIONS
 
Subject to the considerations set forth in 'ERISA Considerations' in this
propectus supplement and in the prospectus, the Class A Certificates may be
acquired by a pension or other employee benefit plan subject to the Employee
Retirement Income Security Act of 1974 or to Section 4975 of the Internal
Revenue Code of 1986.
 
A fiduciary of an employee benefit plan must determine that the purchase of a
certificate is consistent with its fiduciary duties under
applicable law and does not result in a nonexempt prohibited transaction under
applicable law.
 
See 'ERISA Considerations' in this prospectus supplement and in the prospectus.
 
LEGAL INVESTMENT
 
The offered certificates will not be 'mortgage related securities' for purposes
of the Secondary Mortgage Market Enhancement Act of 1984.
 
See 'Legal Investment' in this prospectus supplement and in the prospectus.

                                  RISK FACTORS
 
 THE FOLLOWING INFORMATION, WHICH YOU SHOULD CAREFULLY CONSIDER, IDENTIFIES
 CERTAIN SIGNIFICANT SOURCES OF RISK ASSOCIATED WITH AN INVESTMENT IN THE
 CERTIFICATES. YOU SHOULD ALSO CAREFULLY CONSIDER THE INFORMATION SET FORTH
 UNDER 'RISK FACTORS' IN THE PROSPECTUS.
 
<TABLE>

<S>                                         <C>

YOU MAY HAVE DIFFICULTY SELLING YOUR
  CERTIFICATES............................  Each underwriter intends to make a secondary market in the
                                            certificates purchased by it, but no underwriter has any obligation
                                            to do so. We cannot assure you that a secondary market will develop
                                            or, if it develops, that it will continue. Consequently, you may not
                                            be able to sell your certificates readily or at prices that will
                                            enable you to realize your desired yield. The market values of the
                                            certificates are likely to fluctuate; these fluctuations may be
                                            significant and could result in significant losses to you.

                                            The secondary 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 structured to meet the
                                            investment requirements of limited categories of investors.

SUBPRIME MORTGAGE LOANS ARE SUBJECT TO
  GREATER RISK OF DELINQUENCY AND LOSS....  The mortgage loans in the mortgage pool were made to borrowers with
                                            prior credit difficulties and do not satisfy the underwriting
                                            guidelines for mortgage loans eligible for sale to the Federal
                                            National Mortgage Association ('FNMA') or the Federal Home Loan
                                            Mortgage Corporation ('FHLMC'). It is expected that the rates of
                                            delinquency, bankruptcy and foreclosure for the mortgage loans will
                                            be higher, and may be substantially higher, than that of mortgage
                                            loans underwritten in accordance with FNMA and FHLMC standards. See
                                            'The Mortgage Pool -- Underwriting Standards.'

                                            The Seller began purchasing subprime mortgage loans in April 1995. As
                                            a result, the Seller has only limited delinquency, foreclosure and
                                            loss experience with respect to the subprime mortgage loans that it
                                            has purchased. Although IndyMac, Inc. believes that the underwriting
                                            standards used in underwriting the mortgage loans are consistent with
                                            industry standards and that the servicing practices used to service
                                            the mortgage loans are consistent with industry standards, there can
                                            be no assurance that the foreclosure and loss experience on the
                                            mortgage loans will be consistent with industry norms.

CASH FLOW CONSIDERATIONS AND RISKS COULD
  CAUSE PAYMENT DELAYS AND LOSSES.........  Substantial delays could result while liquidating delinquent mort-
                                            gage loans. Resulting shortfalls in distributions to
                                            certificateholders could occur if the certificate insurer were unable
                                            to perform its obligations under the policy. Further, liquidation
                                            expenses (such as legal fees, real estate taxes, and maintenance and
                                            preservation expenses) will reduce the security for the related
                                            mortgage loans and in turn reduce the proceeds payable to
                                            certificateholders. In the event any of the mortgaged properties fail
                                            to provide adequate security for the related mortgage loans, you
                                            could experience a loss if the certificate insurer were unable to
                                            perform its obligations under the policy.

UNPREDICTABILITY AND EFFECT OF
  PREPAYMENTS.............................  A majority of the borrowers under the mortgage loans generally cannot
                                            prepay their mortgage loans during the first one, two, three, four or
                                            five years after origination without incurring prepayment penalties.
                                            However, we cannot predict the rate at which borrowers will repay
                                            their mortgage loans. A prepayment of a mortgage loan will usually
                                            result in a prepayment on the certificates

                                            If you purchase your certificates at a discount and principal is
                                             repaid slower than you anticipate, then your yield may be lower than
                                             you anticipate.

                                            If you purchase your certificates at a premium and principal is
                                             repaid faster than you anticipate, then your yield may be lower than
                                             you anticipate.

                                            None of the prepayment penalties will be distributed to holders of
                                            the offered certificates.

                                            See 'Yield, Prepayment and Maturity Considerations' for a description
                                            of factors that may influence the rate and timing of prepayments on
                                            the mortgage loans.

WITHDRAWAL OR DOWNGRADING OF INITIAL
  RATINGS WILL AFFECT THE VALUE OF THE
  CERTIFICATES............................  The rating of the certificates will depend primarily on an assessment
                                            by the rating agencies of the mortgage loans and upon the
                                            claims-paying ability of the certificate insurer. Any reduction in a
                                            rating assigned to the claims-paying ability of the certificate
                                            insurer may result in a reduction in the rating of the certificates.
                                            A reduction in the rating assigned to the certificates probably would
                                            reduce the market value of the certificates and may affect your
                                            ability to sell them. The rating by each of the rating agencies of
                                            the certificates is not a recommendation to purchase, hold or sell
                                            the certificates since that rating does not address the market price
                                            or suitability for a particular investor. The rating agencies may
                                            reduce or withdraw the ratings on the certificates at any time they
                                            deem appropriate. In general, the ratings address credit risk and do
                                            not address the likelihood of prepayments.

JUNIOR LIEN PRIORITY COULD RESULT IN
  PAYMENT DELAY OR LOSS...................  15.93% of the mortgage loans in Loan Group 1 (by principal balance as
                                            of March 1, 1999) are secured by second liens on mortgaged
                                            properties. The master servicer has the power under certain
                                            circumstances to consent to a new mortgage lien on the mortgaged
                                            property having priority over the mortgage loan in the trust fund.
                                            Mortgage loans secured by second mortgages are entitled to proceeds
                                            that remain from the sale of the related mortgaged property after any
                                            related senior mortgage loan and prior statutory liens have been
                                            satisfied. In the event that the remaining proceeds are insufficient
                                            to satisfy the mortgage loans secured by second mortgages and prior
                                            liens in the aggregate and the certificate insurer is unable to
                                            perform its obligations under the policy, you will bear

                                            the risk of delay in distributions while any deficiency judgment
                                             against the borrower is sought and

                                            the risk of loss if the deficiency judgment cannot be obtained or is
                                             not realized upon.

DISTRIBUTIONS TO AND RIGHTS OF INVESTORS
  COULD BE ADVERSELY AFFECTED BY THE
  BANKRUPTCY OR INSOLVENCY OF CERTAIN
  PARTIES.................................  IndyMac, Inc. will treat its sale of the mortgage loans to the
                                            depositor as a sale of the mortgage loans. However, if IndyMac, Inc.
                                            becomes bankrupt, the trustee in bankruptcy of IndyMac, Inc. may
                                            argue that the mortgage loans were not sold but were only pledged to
                                            secure a loan to IndyMac, Inc. If that argument is made you could
                                            experience delays or reductions in payments on the certificates. The
                                            depositor will warrant in the pooling and servicing agreement that
                                            the transfer of the mortgage loans by it to the trust fund is either
                                            a valid transfer and assignment of the mortgage loans to the trust
                                            fund or the grant to the trust fund of a security interest in the
                                            mortgage loans.
 
                                            If the master servicer becomes bankrupt, the bankruptcy trustee or
                                            receiver may have the power to prevent the trustee or the
                                            certificateholders from appointing a successor master servicer.
 
DEVELOPMENTS IN CALIFORNIA COULD HAVE
  DISPROPORTIONATE EFFECT ON THE POOL OF
  MORTGAGE LOANS DUE TO GEOGRAPHIC
  CONCENTRATION OF MORTGAGED PROPERTIES...  Approximately 38.76% of the mortgage loans expected to be in the
                                            trust on the cut-off date are secured by property in California.
                                            Property in California may be more susceptible than homes located in
                                            other parts of the country to certain types of uninsurable hazards,
                                            such as earthquakes, floods, mudslides and other natural disasters.
                                            In addition:
 
                                            Economic conditions in California (which may or may not affect real
                                             property values) may affect the ability of borrowers to repay their
                                             loans on time;
 
                                            Declines in the California residential real estate market may reduce
                                             the values of properties located in California, which would result
                                             in an increase in the loan-to-value ratios; and
 
                                            Any increase in the market value of properties located in California
                                             would reduce the loan-to-value ratios and could, therefore, make
                                             alternative sources of financing available to the borrowers at lower
                                             interest rates, which could result in an increased rate of
                                             prepayment of the mortgage loans.
 
YOUR RETURN COULD BE ADVERSELY AFFECTED BY
  DELINQUENT MORTGAGE LOANS...............  Approximately 6.17% of the mortgage loans in the trust fund (by
                                            principal balance) are between 30 and 59 days delinquent as of March
                                            1, 1999. Mortgage loans that are already delinquent may increase the
                                            risk that the trust fund will experience a loss.
 
CERTIFICATES MAY NOT BE APPROPRIATE FOR
  CERTAIN INVESTORS.......................  The offered certificates may not be an appropriate investment for
                                            investors who do not have sufficient resources or expertise to
                                            evaluate the particular characteristics of the applicable class of
                                            offered certificates. This may be the case because, among other
                                            things:

                                            The yield to maturity of offered certificates purchased at a price
                                             other than par will be sensitive to the uncertain rate and timing of
                                             principal prepayments on the mortgage loans;

                                            The rate of principal distributions on and the weighted average lives
                                             of the offered certificates will be sensitive to the uncertain rate
                                             and timing of principal prepayments on the mortgage loans and the
                                             priority of principal distributions among the classes of
                                             certificates. Accordingly, the offered certificates may be an
                                             inappropriate investment if you require a distribution of a
                                             particular amount of principal on a specific date or an otherwise
                                             predictable stream of distributions;

                                            You may not be able to reinvest amounts distributed in respect of
                                             principal on an offered certificate (which, in general, are expected
                                             to be greater during periods of relatively low interest rates) at a
                                             rate at least as high as the pass-through rate applicable to your
                                             certificate; or

                                            A secondary market for the offered certificates may not develop or
                                             provide certificateholders with liquidity of investment.

                                            You should also carefully consider the further risks discussed above
                                            and under the heading 'Yield, Prepayment and Maturity Considerations'

INDYMAC ONLY RECENTLY ACQUIRED DIRECT
  MORTGAGE LOAN SERVICING CAPABILITIES....  Although IndyMac, Inc. has been a master servicer of mortgage loans
                                            since 1993, IndyMac, Inc. only began to directly service mortgage
                                            loans in the first half of 1998. Because of IndyMac, Inc.'s relative
                                            lack of experience in the direct servicing of mortgage loans, the

                               THE MORTGAGE POOL
 
GENERAL
 
     The Depositor will purchase the Mortgage Loans from IndyMac, Inc.
('IndyMac') pursuant to the Pooling and Servicing Agreement (the 'Agreement')
dated as of the Cut-off Date among IndyMac, as Seller and Master Servicer, the
Depositor and the Trustee (the 'Agreement') and will cause the Mortgage Loans to
be assigned to the Trustee for the benefit of holders of the Certificates (the
'Certificateholders').
 
     Under the Agreement, the Seller will make certain representations,
warranties and covenants to the Depositor relating to, among other things, the
due execution and enforceability of the Agreement and certain characteristics of
the Mortgage Loans and, subject to the limitations described below under
' -- Assignment of Mortgage Loans,' will be obligated to repurchase or
substitute a similar mortgage loan for any Mortgage Loan as to which there
exists deficient documentation or an uncured material breach of any such
representation, warranty or covenant if such breach of representation, warranty
or covenant materially and adversely affects the Certificateholders' or the
Certificate Insurer's interest in such Mortgage Loan; provided, however, that
the Seller will not be obligated to make any such repurchase or substitution (or
cure such breach) if such breach constitutes fraud in the origination of the
affected Mortgage Loan and the Seller did not have knowledge of such fraud. The
Seller will represent and warrant to the Depositor in the Agreement that the
Mortgage Loans were selected from among the outstanding one- to four-family
mortgage loans in the Seller's sub-prime mortgage portfolio as to which the
representations and warranties set forth in the Agreement can be made and that
such selection was not made in a manner intended to adversely affect the
interests of the Certificateholders or the Certificate Insurer. See 'Loan
Program -- Representations by Sellers; Repurchases' in the Prospectus. Under the
Agreement, the Depositor will assign all its right, title and interest in and to
such representations, warranties and covenants (including the Seller's
repurchase obligation) to the Trustee for the benefit of the Certificateholders.
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. IndyMac is
selling the Mortgage Loans without recourse and will have no obligation with
respect to the Certificates in its capacity as Seller other than the repurchase
or substitution obligations described above. The obligations of IndyMac, as
Master Servicer, with respect to the Certificates are limited to the Master
Servicer's contractual servicing obligations under the Agreement.
 
     Certain information with respect to the Mortgage Loans to be included in
the Mortgage Pool is set forth below. Prior to 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 as of the Cut-off Date.
 
     As of the Cut-off Date, the aggregate of the Stated Principal Balances of
the Mortgage Loans is expected to be approximately $193,539,716.66 (the 'Cut-off
Date Principal Balance'). The Mortgage Loans provide for the amortization of the
amount financed over a series of substantially equal monthly payments. The
Mortgage Loans to be included in the Mortgage Pool were acquired by the Seller
in the normal course of its business.
 
     At origination, approximately 5.86% of the Mortgage Loans had stated terms
to maturity of 15 years or less and the remaining Mortgage Loans generally had
stated terms to maturity of 30 years. Each of the Mortgage Loans provides for
payments due on the first day of each month (each, a 'Due Date'). Scheduled
payments ('Scheduled Payments') made by the obligors on the Mortgage Loans (the
'Mortgagors') 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.
 
     Of the Mortgage Loans in Loan Group 1, 390 Mortgage Loans representing
approximately 34.10% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 1, and 202 Mortgage Loans in Loan Group 2, representing
approximately 66.11% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 2, contain prepayment penalties. Prepayment penalties provide that
if the borrower were to prepay the Mortgage Loan in full at any time from the
origination of the Mortgage Loan to a date set forth in the related Note (the
'Prepayment Penalty Period'), the borrower would also have to pay a fee in
addition to the
 
                                      S-12
 <PAGE>
<PAGE>
amount necessary to repay the Mortgage Loan. The Prepayment Penalty Period for
the Mortgage Loans vary from 12 months to 5 years, depending on the terms set
forth in the related Mortgage Note. The amount of the prepayment penalty varies
from state to state. None of the prepayment penalties will be distributed to
holders of the offered Certificates.
 
     With respect to the Mortgage Loans in Loan Group 2, each Mortgage Loan has
a Mortgage Rate subject to adjustment on the Due Date specified in the related
Mortgage Note (the 'Initial Rate Adjustment Date') and every six months (in the
case of 3/27 Adjustable Mortgage Loans, 2/28 Adjustable Mortgage Loans and 6/6
Adjustable Mortgage Loans (each as defined below)) or one year (in the case of
3/1 Adjustable Mortgage Loans and 1 Year CMT Adjustable Mortgage Loans (as
defined below)) thereafter (each such date, an 'Adjustment Date'), equal to (a)
in the case of 3/27 Adjustable Mortgage Loans, 2/28 Adjustable Mortgage Loans
and 6/6 Adjustable Mortgage Loans, the sum, rounded to the nearest one-eighth of
one percentage point (0.125%), of (i) the average of interbank offered rates for
six month U.S. dollar deposits in the London market (the 'Index') based on
quotations of major banks, as published either (x) by FNMA either 30 or 45 days
prior to the Adjustment Date or (y) in the 'Money Rates' section of The Wall
Street Journal as of the first business day of the month prior to the Adjustment
Date, as specified in the related Mortgage Note, and (ii) the margin specified
in the related Mortgage Note and (b) in the case of the 3/1 Adjustable Mortgage
Loans and 1 Year CMT Adjustable Mortgage Loans, the weekly average yield on U.S.
Treasury Securities adjusted to a constant maturity of one year as made
available by the Federal Reserve, in each case as specified in the related
Mortgage Note; provided, however, that the Mortgage Rate will not increase or
decrease on any Adjustment Date by more than (A) with respect to one Mortgage
Loan (representing approximately 0.05% of the Cut-off Date Principal Balance of
Loan Group 2), one-half of one percentage point (0.5%), (B) with respect to 166
Mortgage Loans (representing approximately 67.14% of the Cut-off Date Principal
Balance of Loan Group 2), one percentage point (1%), (C) with respect to 78
Mortgage Loans (representing approximately 16.83% of the Cut-off Date Principal
Balance of Loan Group 2), one and one-half percentage point (1.5%), (D) with
respect to 46 Mortgage Loans (representing approximately 15.37% of the Cut-off
Date Principal Balance of Loan Group 2), two percentage points (2.0%), (E) with
respect to one Mortgage Loan (representing approximately 0.09% of the Cut-off
Date Principal Balance of Loan Group 2), three percentage points (3%) and (F)
with respect to one Mortgage Loan (representing approximately 0.16% of the
Cut-off Date Principal Balance of Loan Group 2), five percentage points (5%)
(the 'Periodic Rate Cap'). Approximately 62.11% of the Mortgage Loans in Loan
Group 2 (by Cut-off Date Principal Balance) have an Initial Rate Adjustment Date
occurring on the Due Date following the second anniversary of the date of
origination (such Mortgage Loans, '2/28 Adjustable Mortgage Loans').
Approximately 10.28% of the Mortgage Loans in Loan Group 2 (by Cut-off Date
Principal Balance) have an Initial Rate Adjustment Date occurring on the Due
Date following the third anniversary of the date of origination (such Mortgage
Loans, '3/27 Adjustable Mortgage Loans'). Approximately 12.07% of the Mortgage
Loans in Loan Group 2 have an Initial Rate Adjustment Date occurring on the
sixth Due Date following the related date of origination (such Mortgage Loans,
'6/6 Adjustable Mortgage Loans'). Approximately 12.63% of the Mortgage Loans in
Loan Group 2 (by Cut-off Date Principal Balance) have an Initial Rate Adjustment
Date occurring on the Due Date following the third anniversary of the date of
origination (such Mortgage Loans, '3/1 Adjustable Mortgage Loans').
Approximately 2.91% of the Mortgage Loans in Loan Group 2 (by Cut-off Date
Principal Balance) have an Initial Rate Adjustment Date occurring on the Due
Date following the first anniversary of the date of origination (such Mortgage
Loans, '1 Year CMT Adjustable Mortgage Loans').
 
     All of the Mortgage Loans in Loan Group 2 provide that over the life of the
Mortgage Loan the Mortgage Rate will in no event be more than the Mortgage Rate
fixed at origination plus a fixed number of percentage points specified in the
related Mortgage Note (such rate, the 'Maximum Rate'). The Mortgage Loans in
Loan Group 2 are generally not subject to minimum Mortgage Rates. Effective with
the first payment due on a Mortgage Loan in Loan Group 2 after each related
Adjustment Date, the Scheduled Payment will be adjusted to an amount which will
pay interest at the adjusted rate and fully amortize the then-outstanding
principal balance of the Mortgage Loan in Loan Group 2 over its remaining term.
If the Index ceases to be published or is otherwise unavailable, the Master
Servicer will select an alternative index based upon comparable information.
 
     Each Mortgage Loan in Loan Group 2 is, by its terms, assumable in
connection with a transfer of the related Mortgaged Property if the proposed
transferee submits certain information to the Master Servicer required to enable
it to evaluate the transferee's ability to repay such Mortgage Loan and if the
Master Servicer reasonably determines that the security for such Mortgage Loan
would not be impaired by the assumption. The Mortgage Loans in Loan Group 1 are
subject to the 'due-on-sale' provisions included therein.

     All Mortgage Loans in Loan Group 1 were originated on or after December 15,
1995. All Mortgage Loans in Loan Group 2 were originated on or after November
13, 1995.
 
     The latest stated maturity date of any Mortgage Loan in Loan Group 1 is
April 1, 2029. The earliest stated maturity date of any Mortgage Loan in Loan
Group 1 is January 1, 2006. The latest stated maturity date of any Mortgage Loan
in Loan Group 2 is April 1, 2029. The earliest stated maturity date of any
Mortgage Loan in Loan Group 2 is April 1, 2013.
 
     As of the Cut-off Date, 68 Mortgage Loans in Loan Group 1 (representing
approximately 5.62% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 1) and 25 Mortgage Loans in Loan Group 2 (representing
approximately 7.70% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 2) were between 30 and 59 days delinquent. As of the Cut-off Date,
no Mortgage Loan in either Loan Group was delinquent more than 59 days.
 
     None of the Mortgage Loans will be subject to any buydown agreement. No
Mortgage Loan provides for deferred interest or negative amortization.
 
     None of the Mortgage Loans in either of the Loan Groups were originated in
connection with the relocation of employees of various corporate employers. One
of the Mortgage Loans in Loan Group 2 is convertible into a fixed-rate mortgage
loan.
 
     Of the Mortgage Loans in Loan Group 1, 849 Mortgage Loans (representing
approximately 84.07% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 1) are secured by first liens on the related Mortgaged Properties,
and 519 Mortgage Loans in Loan Group 1 (representing approximately 15.93% of the
Cut-off Date Principal Balance of the Mortgage Loans in Loan Group 1) are
secured by second liens on the related Mortgaged Properties. All of the Mortgage
Loans in Loan Group 2 are secured by first liens on the related Mortgaged
Properties.
 
     Of the Mortgage Loans in Loan Group 1, 29 Mortgage Loans, representing
approximately 2.46% of the Cut-off Date Principal Balance of the Mortgage Loans
in Loan Group 1, had a Loan-to-Value Ratio or Combined Loan-to-Value Ratio (as
applicable) at origination of more than 95%. No Mortgage in Loan Group 1 had a
Loan-to-Value Ratio or Combined Loan-to-Value Ratio at origination of more than
100%. Three Mortgage Loans in Loan Group 2, representing approximately 0.78% of
the Cut-off Date Principal Balance of the Mortgage Loans in Loan Group 2, had a
Loan-to-Value Ratio at origination of more than 95%. Except for 620 Mortgage
Loans in Loan Group 1, representing approximately 31.64% of the Cut-off Date
Principal Balance of the Mortgage Loans in Loan Group 1, and except for 62
Mortgage Loans in Loan Group 2, representing approximately 19.19% of the Cut-off
Date Principal Balance of the Mortgage Loans in Loan Group 2, each Mortgage Loan
with a Loan-to-Value Ratio or Combined Loan-to-Value Ratio (as applicable) 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 FNMA,
FHLMC or any nationally recognized statistical rating organization, which 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 (i) after the date on which the related Loan-to-Value Ratio or
Combined Loan-to-Value Ratio (as applicable) 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 or (ii) if maintaining such policy is prohibited by
applicable law. See ' -- Underwriting Standards' herein.
 
     The 'Loan-to-Value Ratio' of a Mortgage Loan at any given time is the
fraction, expressed as a percentage, the numerator of which is the original
principal balance of the related Mortgage Loan and the denominator of which is
the Collateral Value of the related Mortgaged Property. The 'Combined
Loan-to-Value Ratio' of a Mortgage Loan at any given time is the ratio,
expressed as a percentage, of (i) the sum of (a) the original principal balance
of the Mortgage Loan and (b) the outstanding principal balance at the date of
origination of the Mortgage Loan of any senior mortgage loans(s) or, in the case
of any open-ended senior mortgage loan, the maximum available line of credit
with respect to such mortgage loan at origination, regardless of any lesser
amount actually outstanding at the date of origination of the Mortgage Loan, to
(ii) the
 
                                      S-14
 <PAGE>
<PAGE>
Collateral Value of the related Mortgaged Property. The 'Collateral Value' of
the Mortgaged Property, other than with respect to certain Mortgage Loans the
proceeds of which were used to refinance an existing mortgage loan (each, a
'Refinance Loan'), is the lesser of (a) the appraised value determined in an
appraisal obtained by the originator at origination of such Mortgage Loan and
(b) the sales price for such Mortgaged Property. In the case of Refinance Loans,
the Collateral Value of the related Mortgaged Property is generally the
appraised value thereof determined in an appraisal obtained at the time of
refinancing. 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 or Combined Loan-to-Value Ratios (as
applicable) might not be a reliable indicator of the rates of delinquencies,
foreclosures and losses that could occur with respect to such Mortgage Loans.
 
     'FICO Credit Scores' are obtained by many mortgage lenders in connection
with mortgage loan applications to help assess a borrower's credit-worthiness.
FICO Credit Scores are generated by models developed by a third party which
analyze data on consumers in order to establish patterns which are believed to
be indicative of the borrower's probability of default. The FICO Credit Score is
based on a borrower's historical credit data, including, among other things,
payment history, delinquencies on accounts, levels of outstanding indebtedness,
length of credit history, types of credit, and bankruptcy experience. FICO
Credit Scores range from approximately 250 to approximately 900, with higher
scores indicating an individual with a more favorable credit history compared to
an individual with a lower score. However, a FICO Credit Score purports only to
be a measurement of the relative degree of risk a borrower represents to a
lender, i.e., that a borrower with a higher score is statistically expected to
be less likely to default in payment than a borrower with a lower score. In
addition, it should be noted that FICO Credit Scores were developed to indicate
a level of default probability over a two-year period which does not correspond
to the life of a mortgage loan. Furthermore, FICO Credit Scores were not
developed specifically for use in connection with mortgage loans, but for
consumer loans in general. Therefore, a FICO Credit Score does not take into
consideration the effect of mortgage loan characteristics (which may differ from
consumer loan characteristics) on the probability of repayment by the borrower.
There can be no assurance that a FICO Credit Score will be an accurate predictor
of the likely risk or quality of the related Mortgage Loan.
 
     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%.

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 and the Certificate Insurer
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 the
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, the
original instrument creating a first or second 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 Mortgage Loans to the Trustee (or its nominee) will be recorded in the
appropriate public office for real property records, except in states such as
California 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
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 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 as provided in
the Agreement in the case of missing documents not returned from the public
recording office), the Seller will be obligated to repurchase the related
Mortgage Loan from the Trust Fund. Rather than repurchase the Mortgage Loan as
provided above, the Seller may remove such Mortgage Loan (a 'Deleted Mortgage
Loan') from the Trust Fund and substitute in its place 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 Trustee to the effect that such substitution will not
disqualify the Trust Fund as a REMIC or result in a prohibited transaction tax
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 Seller and held for distribution to the Certificateholders
on the related Distribution Date (a 'Substitution Adjustment Amount')), (ii)
have a current Mortgage Rate not lower than, and not more than 1% per annum
higher than, that of the Deleted Mortgage Loan, (iii) with respect to the
Mortgage Loans in Loan Group 2, (a) have a Mortgage Rate based upon the Index
and a Margin at least equal to and not greater than 50 basis points higher than
the Deleted Mortgage Loan, (b) have a Mortgage Rate subject to a Maximum Rate
that is no less than the Maximum Rate applicable to the Deleted Mortgage Loan,
(c) have Adjustment Dates that are no more or less frequent than the Deleted
Mortgage Loan, (iv) have a Loan-to-Value Ratio or Combined Loan-to-Value Ratio
(as applicable) not higher than that of the Deleted Mortgage Loan, (v) have a
remaining term to maturity not greater than (and not more than one year less
than) that of the Deleted Mortgage Loan, (vi) comply with all of the
representations and warranties set forth in the Agreement as of the date of
substitution, and (vii) be otherwise acceptable to the Certificate Insurer. 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.
 
UNDERWRITING STANDARDS
 
     The Mortgage Loans were originated in accordance with IndyMac's
underwriting standards for sub-prime mortgage loans described below. IndyMac
began operating a mortgage conduit program in 1993 and began in April 1995 to
purchase mortgage loans made to borrowers with prior credit difficulties
(so-called 'subprime mortgage loans'). All of the subprime mortgage loans
purchased by IndyMac are 'conventional non-conforming mortgage loans' (i.e.,
loans which are not insured by the Federal Housing Authority or partially
guaranteed by
 
                                      S-21
 <PAGE>
<PAGE>
the Veterans Administration and which do not qualify for sale to FNMA or FHLMC)
secured by first or second liens on one- to four-family residential properties.
 
     IndyMac purchases subprime mortgage loans from sellers either under flow or
bulk purchase arrangements, the terms of which may vary from seller to seller.
Such sellers are required to be HUD approved mortgagees.
 
     IndyMac's underwriting standards are primarily intended to evaluate the
value and adequacy of the mortgaged property as collateral for the proposed
mortgage loan, as well as the type and intended use of the mortgaged property.
Its underwriting standards are less stringent than the standards generally
acceptable to FNMA and FHLMC with regard to the borrower's credit standing and
repayment ability. Borrowers who qualify under the IndyMac underwriting
standards generally have payment histories and debt-to-income ratios that would
not satisfy FNMC and FHLMC underwriting guidelines and may have a record of
major derogatory credit items, such as outstanding judgments or prior
bankruptcies, or lower credit scores. As a result, the rates of delinquency,
bankruptcy and foreclosure for such mortgage loans could be higher, and may be
substantially higher, than that of mortgage loans underwritten in accordance
with FNMA and FHLMC standards.
 
     Each of the subprime mortgage loans purchased by IndyMac is assigned to one
of six credit levels based on the prospective mortgagor's FICO Credit Score,
installment debt credit history, judgments, charge-offs and accounts assigned
for collection. IndyMac also accepts loans underwritten under one of four
documentation programs: Full/Alternate Documentation, Reduced Documentation, No
Ratio Documentation and No Income/No Asset. For each credit level and
documentation program, IndyMac has a maximum permitted loan amount, a maximum
Loan-to-Value Ratio or Combined Loan-to-Value Ratio (as applicable) and, in some
cases, a limitation on the loan purpose. The maximum debt to income ratio for
all loans, other than those with primary mortgage insurance, is 55%. Such
limitation, however, may be waived on a case by case basis.
 
     Under the Full/Alternate Documentation Program, the prospective borrower's
employment, income and assets are verified through written or telephonic
communications. Mortgage loans in all six credit levels may be submitted under
this program. Under each of the Reduced Documentation Program and the No Ratio
Program, more emphasis is placed on the value and adequacy of the mortgaged
property as collateral and other assets of the borrower than on credit
underwriting. Under each of these programs, certain credit underwriting
documentation concerning income or income verification and/or employment
verification is waived. Under the No Income/No Asset Program, credit
underwriting documentation concerning income, employment verification and asset
verification is waived and income ratios are not calculated.
 
     Only mortgage loans for primary residences in credit Levels 0 and I+ may be
submitted under the No Income/No Asset Program, and the maximum Loan-to-Value
Ratios or Combined Loan-to-Value Ratios (as applicable) under this program are
less than those under the Full Documentation, Alternative Documentation, Reduced
Documentation and No Ratio Programs.
 
                          SERVICING OF MORTGAGE LOANS
 
THE MASTER SERVICER
 
     IndyMac, Inc. ('IndyMac'), a Delaware corporation, will act as the Master
Servicer of the Mortgage Loans pursuant to the Agreement.
 
     During the first half of 1998 IndyMac acquired a servicing platform (i.e.,
the servicing business operations but not mortgage loans) from First of America
Loan Services, Inc. in order to provide IndyMac with direct servicing
capabilities for mortgage loans, including sub-prime mortgage loans. Prior to
that time, IndyMac had master servicing capabilities but no direct servicing
capabilities. As of the Closing Date, it is expected that the Master Servicer
will directly service 99.1% of Mortgage Loans in Loan Group 1 and 85.1% of the
Mortgage Loans in Loan Group 2, in each case by Cut-off Date Principal Balance.
The remainder of the Mortgage Loans in each Loan Group will be directly serviced
by Countrywide Home Loans, Inc., an affiliate of the Master Servicer.
 
     As of December 31, 1998, IndyMac provided servicing for approximately
$10.56 billion in conventional mortgages.
 
     The principal executive offices of IndyMac are located at 155 North Lake
Avenue, Pasadena, California 91101.

SERVICING AND COLLECTION PROCEDURES
 
     IndyMac has established standard policies for the servicing and collection
of sub-prime mortgage loans. Servicing includes, but is not limited to,
collecting, aggregating and remitting mortgage loan payments, accounting for
principal and interest, holding escrow (impound) funds for payment of taxes and
insurance, making inspection as required of the mortgaged properties,
preparation of tax related information in connection with the mortgage loans,
supervision of delinquent mortgage loans, loss mitigation efforts, foreclosure
proceedings and, if applicable, the disposition of mortgaged properties, and
generally administering the mortgage loans, for which it receives servicing
fees. Pursuant to the Agreement, the Master Servicer is permitted to contract
with one or more subservicers, with the consent of the Certificate Insurer, to
perform its servicing duties under the Agreement, however, the Master Servicer
will remain liable for its duties and obligations under the Agreement as if the
Master Servicer alone were servicing the Mortgage Loans.
 
FORECLOSURE, DELINQUENCY AND LOSS EXPERIENCE
 
     The tables below set forth foreclosure, delinquency and loss experience for
sub-prime mortgage loans originated or acquired by IndyMac and serviced or
master serviced by IndyMac. Since IndyMac only began master servicing sub-prime
mortgage loans in April 1995, the delinquency and loss statistics may be
affected by the size and relative lack of seasoning of the portfolio because
many of such loans were not outstanding long enough to give rise to some or all
of the periods of delinquency and loss indicated in the charts below. In
addition, because IndyMac only recently began directly servicing mortgage loans,
the foreclosure, delinquency and loss experience set forth below may not be
indicative of IndyMac's foreclosure, delinquency and loss experience for future
periods. ACCORDINGLY, THE INFORMATION IN THE TABLES BELOW SHOULD NOT BE
CONSIDERED AS A BASIS FOR ASSESSING THE LIKELIHOOD, AMOUNT, OR SEVERITY OF
DELINQUENCY OR LOSSES ON THE MORTGAGE LOANS, AND NO ASSURANCES CAN BE GIVEN THAT
THE FORECLOSURE EXPERIENCE PRESENTED IN THE PARAGRAPH BELOW THE TABLE WILL BE
INDICATIVE OF SUCH EXPERIENCE ON THE MORTGAGE LOANS.
 
     The following table summarizes the delinquency experience of IndyMac's
sub-prime mortgage loans as of December 31, 1996, December 31, 1997 and
December 31, 1998 on approximately $399 million, $496 million and $1.21 billion,
respectively. A mortgage loan is characterized as delinquent if the borrower has
not paid the scheduled payment due by the due date specified in the related
mortgage note. The table below excludes sub-prime mortgage loans where the
borrower has filed for bankruptcy.

     There can be no assurance that factors beyond IndyMac's control, such as
national or local economic conditions or downturns in the real estate markets of
its lending areas, will not result in increased rates of delinquencies and
foreclosure losses in the future. For example, a general deterioration of the
real estate market regions where the Mortgaged Properties are located may result
in increases in delinquencies of loans secured by real estate, slower absorption
rates of real estate into the market and lower sales prices for real estate. A
general weakening of the economy may result in decreases in the financial
strength of borrowers and decreases in the value of collateral serving as
collateral for loans. If the real estate market and economy continue to decline,
IndyMac may experience an increase in delinquencies on the loans it services and
higher net losses on liquidated loans.
 
YEAR 2000 COMPLIANCE
 
     The Master Servicer is conducting a comprehensive review of its computer
systems to determine if they will be affected by the Year 2000 issue -- computer
programs and embedded logic devices that utilize two digits rather than four to
define the applicable year may fail to properly recognize date-sensitive
information when the year changes to 2000. Generally, the Master Servicer is not
affected by issues resulting from the use of 'legacy' computer systems and
software because it commenced its active operating business within the past five
years. In the event that computer problems arise out of a failure of the Master
Servicer to identify and resolve Year 2000 compliance issues, or in the event
that the computer systems of service providers or the Trustee are not fully Year
2000 compliant, the resulting disruptions in the collection or distribution of
receipts on the Mortgage Loans could materially, adversely affect the holders of
the Offered Certificates.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Expense Fees with respect to the Mortgage Pool are payable out of the
interest payments on each Mortgage Loan. The 'Expense Fees' will be the Expense
Fee Rate times the Stated Principal Balance of each Mortgage Loan. The 'Expense
Fee Rate' will equal approximately 0.51% per annum. The Expense Fees consist of
(a) master servicing compensation payable to the Master Servicer in respect of
its master servicing activities (the 'Master Servicing Fee'), and (b) fees
payable to the Trustee in respect of its activities as trustee under the
Agreement. The Master Servicing Fee will be 0.50% per annum of the Stated
Principal Balance of each Mortgage Loan. The Master Servicer is obligated to pay
certain ongoing expenses associated with the Trust Fund and incurred by the
Master Servicer in connection with its responsibilities under the Agreement and
such amounts will be paid by the Master Servicer out of the Master Servicing
Fee. The amount of the Master Servicing Fee is subject to adjustment with
respect to prepaid Mortgage Loans, as described herein under ' -- Adjustment to
Master Servicing Fee in Connection with Certain Prepaid Mortgage Loans.' The
Master Servicer will also be entitled to receive late payment fees, assumption
fees and other similar charges (but not prepayment penalties). The Master
Servicer will be entitled to receive all reinvestment income earned on amounts
on deposit in the Certificate Account and the Distribution Account. The
'Adjusted Net Mortgage Rate' of a Mortgage Loan is the Mortgage Rate thereof
minus the related Expense Fee Rate.
 
ADJUSTMENT TO MASTER SERVICING FEE IN CONNECTION WITH CERTAIN PREPAID MORTGAGE
LOANS
 
     When a borrower prepays a Mortgage Loan between Due Dates, the borrower is
required to pay interest on the amount prepaid only to the date of prepayment
and not thereafter. Principal prepayments by borrowers received during a
Remittance Period will be distributed to Certificateholders on the related
Distribution Date. Pursuant to the Agreement, the Master Servicing Fee for any
month will be reduced, but not more than one-quarter of such Master Servicing
Fee (such amount, the 'Compensating Interest'), by an amount with respect to
each such prepaid Mortgage Loan sufficient to pass through to Certificateholders
the full amount of interest to which they would be entitled in respect of such
Mortgage Loan on the related Distribution Date. If shortfalls in interest as a
result of prepayments in any Remittance Period exceed an amount equal to
one-quarter of the Master Servicing Fee otherwise payable on the related
Distribution Date, the amount of interest available to be distributed to
Certificateholders will be reduced by the amount of such excess. Any such
reduction in interest distributable to the Offered Certificates will not be
covered by the Policy. See 'Description of the Certificates -- Distributions of
Interest and Principal' and 'Yield, Prepayment and Maturity
Considerations -- Prepayment Considerations and Risks' herein.
 
                                      S-24
 <PAGE>
<PAGE>
ADVANCES
 
     Subject to the following limitations, the Master Servicer will be required
to advance prior to each Distribution Date, from its own funds or funds in the
Certificate Account 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 Master Servicing Fee with respect to the
related Mortgage Loans) which were due on the related Due Date and which were
delinquent on the related Determination Date, together with an amount equivalent
to interest on each Mortgage Loan as to which the related Mortgaged Property has
been acquired by the Trust Fund through foreclosure or deed-in-lieu of
foreclosure ('REO Property') (any such advance, an 'Advance'). The
'Determination Date' means as to any Distribution Date, the 18th day of each
month, or if such day is not a business day, the first business day thereafter;
provided, that if such next business day is less than two business days prior to
the related Distribution Date, then the Determination Date shall be the first
business day preceding the 18th day of such month.
 
     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 Master Servicer is obligated to make Advances with respect
to delinquent payments of principal or interest on each Mortgage Loan unless
such Advances are, in its reasonable judgment, not recoverable from future
payments and collections or insurance payments or proceeds of liquidation of the
related Mortgage Loan. If the Master 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 the Master
Servicer to make an Advance as required under the Agreement with respect to the
Certificates will constitute an Event of Default thereunder (as described in the
Prospectus), in which case the Trustee or the successor master servicer will be
obligated to make any such Advance, in accordance with the terms of the
Agreement.
 
CERTAIN MODIFICATIONS AND REFINANCINGS
 
     The Master Servicer may modify any Mortgage Loan upon the request of the
related Mortgagor, provided that the Master Servicer purchases such Mortgage
Loan from the Trust Fund immediately following such modification. Any such
modification may not be made unless the Master Servicer determines that the
modification includes a change in the interest rate on the related Mortgage Loan
to approximately a prevailing market rate. Any such purchase will be for a price
equal to 100% of the outstanding principal balance of such Mortgage Loan, plus
accrued and unpaid interest thereon up to the date of purchase at the applicable
Adjusted Net Mortgage Rate, net of any unreimbursed advances of principal and
interest thereon made by the Master Servicer. The Master Servicer will deposit
the purchase price in the Certificate Account within one Business Day of the
purchase of such Mortgage Loan. Such purchases may occur when prevailing
interest rates are below the interest rates on the Mortgage Loans and Mortgagors
request modifications as an alternative to refinancings. The Master Servicer
will indemnify the Trust Fund against liability for any prohibited transactions
taxes and any related interest, additions or penalties imposed on any of the
REMICs as a result of any such modification or purchase.
 
EVENTS OF DEFAULT
 
     In addition to those Events of Deafult (as defined in the Prospectus)
described under 'The Agreements -- Events of Default; Rights Upon Events of
Default' in the Prospectus, upon the occurrence of certain loss and delinquency
triggers with respect to the Mortgage Loans or upon the occurrence of certain
other defaults set forth in the Agreement, the Master Servicer may be removed as
master servicer of such Mortgage Loans by the Certificate Insurer in accordance
with the terms of the Agreement and the Insurance Agreement.

issued as a single Certificate in a denomination of $100.
 
BOOK-ENTRY CERTIFICATES
 
     Each Class of Book-Entry Certificates will be issued in one or more
certificates which equal the aggregate initial Class Certificate 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 may hold such beneficial interests in
the Book-Entry Certificates in minimum denominations representing an original
principal amount of $25,000 and integral multiples of $1,000 in excess thereof.
One investor of each Class of Book-Entry Certificates may hold a beneficial
interest therein that is not an integral multiple of $1,000. 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 in the Prospectus under 'Description of the
Securities -- Book-Entry Registration of Securities' no person acquiring a
Book-Entry Certificate (each, a 'beneficial owner') will be entitled to receive
a physical certificate representing such Certificates (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 financial intermediaries 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
 
                                      S-26

<PAGE>
procedures creating and affecting the Depository, and to the financial
intermediaries 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 of
Securities' in the Prospectus.
 
PAYMENTS ON MORTGAGE LOANS; ACCOUNTS
 
     On or prior to the Closing Date, the Trustee will establish an account (the
'Distribution Account'), which shall be maintained with the Trustee in trust for
the benefit of the Certificateholders. On or prior to the second business day
immediately preceding each Distribution Date, the Master Servicer will withdraw
from the Certificate Account the amount of Available Funds for such Distribution
Date and will deposit such Available Funds in the Distribution Account. Funds
credited to the Certificate Account or the Distribution Account may be invested
for the benefit and at the risk of the Master 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.
 
     '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
on such Mortgage Loans in the related Remittance Period 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 such 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 Master 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 in such Loan Group, by foreclosure or otherwise ('Liquidation
Proceeds') during the related Remittance Period (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 on the
Mortgage Loans in such Loan Group received during the related Remittance Period
(including prepayment penalties) together with all Compensating Interest
thereon; and (iv) amounts received with respect to such Distribution Date as the
Substitution Adjustment Amount or purchase price in respect of a Deleted
Mortgage Loan in such Loan Group or a Mortgage Loan repurchased by the Seller or
the Master Servicer in such Loan Group as of such Distribution Date; reduced by
amounts in reimbursement for Advances previously made with respect to the
Mortgage Loans in such Loan Group and other amounts as to which the Master
Servicer is entitled to be reimbursed pursuant to the Agreement with respect to
such Loan Group.
 
SEPARATE REMIC STRUCTURE
 
     For federal income tax purposes, the Trust Fund will include multiple
segregated asset pools, each of which will be treated as a separate REMIC.
 
DISTRIBUTIONS
 
     Distributions on the Certificates will be made by the Trustee on the 25th
day of each month, or if such day is not a business day, on the first business
day thereafter, commencing in April 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 other
Distribution Date (each, a '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 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.
 
     The Pass-Through Rate for the Fixed Rate Certificates shall be as set forth
on the cover page hereof; provided, however, that, with respect to any
Distribution Date, such Pass-Through Rate will not exceed the
 
                                      S-27
 <PAGE>
<PAGE>
weighted average of the Mortgage Interest Rates then in effect on the beginning
of the related Remittance Period on the Mortgage Loans in Loan Group 1 minus the
sum of the Expense Fee Rate and the premium for the Policy expressed as a per
annum rate. The Pass-Through Rate for the Adjustable Rate Certificates will be
equal to the lesser of (i) One-Month LIBOR plus the Pass-Through Margin for such
Class, and (ii) the weighted average of the Mortgage Interest Rates then in
effect on the beginning of the related Remittance Period on the Mortgage Loans
in Loan Group 2 minus the sum of (a) the Expense Fee Rate, (b) the premium for
the Policy expressed as a per annum rate and (c) with respect to each
Distribution Date after the twelfth Distribution Date, 0.50% (the 'Group 2 WAC
Cap').
 
     The 'Pass-Through Margin' for the Class AV Certificates is 0.29%, with
respect to any Distribution before the Optional Termination Date, and 0.58%,
with respect to any Distribution Date on or after the Optional Termination Date.
 
     On each Distribution Date, distributions in reduction of the Class
Certificate Balance of the Certificates entitled to receive distributions of
principal will be made in an amount equal to the Principal Distribution Amount
for the related Certificate Group. The 'Principal Distribution Amount' for each
Certificate Group and Distribution Date will equal the lesser of (x) the Class
Certificate Balance of the related Class A Certificates and (y) the sum of (i)
the Principal Remittance Amount for such Distribution Date for such Certificate
Group and (ii) the Extra Principal Distribution Amount for such Distribution
Date for such Certificate Group.
 
     On each Distribution Date, the Trustee is required to make the
disbursements and transfers from moneys then on deposit in the Distribution
Account specified below in the following order of priority:
 
          (i) to the Class PF Certificates, the Prepayment Distribution Amount
     for Loan Group 1, and to the Class PV Certificates, the Prepayment
     Distribution Amount for Loan Group 2;
 
          (ii) to the Class R Certificates, Class PF Certificates, Class PV
     Certificates and each Class of Class A Certificates for the related
     Certificate Group, the aggregate of the related Class Optimal Interest
     Distribution Amount and any Unpaid Interest Amounts for such Classes, pro
     rata, based on the amount of interest which each such Class is entitled to
     receive for such Certificate Group on such Distribution Date;
 
          (iii) with respect to Certificate Group 1, the Principal Remittance
     Amount for Certificate Group 1 to the Class R, Class AF and Class PF
     Certificates, sequentially, in that order, until the Class Certificate
     Balances thereof have been reduced to zero; and with respect to Certificate
     Group 2, the Principal Remittance Amount for Certificate Group 2 to the
     Class AV and Class PV Certificates sequentially, in that order, until the
     Class Certificate Balances thereof have been reduced to zero;
 
          (iv) to the Certificate Insurer, the premium for the Policy;
 
          (v) to the Certificate Insurer, any amount owing to the Certificate
     Insurer under the Insurance Agreement;
 
          (vi) any amount remaining after the distributions in clauses (i)
     through (v) above shall be distributed in the following order of priority
     with respect to the Class A Certificates in the related Certificate Group:
 
             (a) on the first Distribution Date only, an amount equal to 50% of
        such remaining amount to the Seller;
 
             (b) to fund the Extra Principal Distribution Amount for such
        Distribution Date to be paid as a component of the Principal
        Distribution Amount and allocated as described in clause (iii) above;
 
          (vii) any amounts remaining after the foregoing distributions with
     respect to a Certificate Group will be distributed with respect to the
     other Certificate Group in the order set forth above in clauses (ii)-(v) to
     the extent any such amount was not otherwise distributed on such
     Distribution Date;
 
          (viii) to the holders of the Class OC Certificates, such amounts, if
     any, as described in the Agreement; and
 
          (ix) to the holders of the Class R Certificates, the remaining amount.
 
     'Basic Principal Amount' means, with respect to any Distribution Date and
each Loan Group, to the extent of funds available therefor as described herein,
the amount equal to the sum of the following amounts (without duplication) with
respect to the immediately preceding Remittance Period: (i) each payment of
principal on a Mortgage Loan in the related Loan Group received or advanced by
the Master Servicer during such Remittance Period, including all full and
partial principal prepayments, (ii) the Liquidation Proceeds on the Mortgage
Loans
 
                                      S-28

substitution of a Mortgage Loan in the related Loan Group as of such
Distribution Date and (v) the allocable portion of the proceeds received with
respect to the termination of the Trust Fund (to the extent such proceeds relate
to principal).
 
     'Certificate Principal Balance' means, for any Class of Certificates, at
any time, the outstanding principal balance of such Class of Certificates at
such time, which shall equal the initial principal balance of such Class of
Certificates reduced by principal payments made on such Class of Certificates at
or prior to such time.
 
     'Class Optimal Interest Distribution Amount', for each Class of interest
bearing Certificates on any Distribution Date shall equal the amount of interest
accrued during the related Interest Accrual Period on the related Class
Certificate Balance; provided that the Class Optimal Interest Distribution
Amount for such Distribution Date will be reduced by prepayment interest
shortfalls on the Mortgage Loans that are not covered by Compensating Interest
on such Distribution Date as described herein under the heading 'Servicing the
Mortgage Loans -- Adjustment to Master Servicing Fee in Connection with Certain
Prepaid Mortgage Loans.'
 
     'Extra Principal Distribution Amount' means, with respect to any
Distribution Date and either Certificate Group, the lesser of (x) the related
Total Monthly Excess Spread for such Distribution Date and (y) the related
Overcollateralization Deficiency Amount for such Distribution Date.
 
     'Overcollateralization Deficiency Amount' means, with respect to any
Distribution Date and either Certificate Group the amount, if any, by which the
related Overcollateralization Target Amount exceeds the related
Overcollateralized Amount on such Distribution Date (after giving effect to
distributions in respect of the related Basic Principal Amount on such
Distribution Date).
 
     'Overcollateralization Release Amount' means, with respect to any
Distribution Date and either Certificate Group, the lesser of (x) the related
Basic Principal Amount for such Distribution Date and (y) the excess, if any, of
(i) the related Overcollateralized Amount for such Distribution Date (assuming
that 100% of the related Basic Principal Amount is applied as a principal
payment on the related Certificate Group on such Distribution Date) over (ii)
the related Overcollateralization Target Amount for such Distribution Date.
 
     The 'Overcollateralization Target Amount' means, with respect to any
Distribution Date and either Certificate Group a specified level of
overcollateralization determined in accordance with the Agreement.
 
     The 'Overcollateralized Amount' means, with respect to any Distribution
Date and either Certificate Group, the amount, if any, by which (i) the
aggregate of the Stated Principal Balances of the Mortgage Loans in the related
Loan Group on the last day of the immediately preceding Remittance Period
exceeds (ii) the aggregate Certificate Principal Balance of the Offered
Certificates in such Certificate Group as of such Distribution Date after giving
effect to distributions to be made on such Distribution Date.
 
     'Prepayment Distribution Amount' means, with respect to each Loan Group,
all amounts representing prepayment penalties from the Mortgage Loans in such
Loan Group received during the related Remittance Period.
 
     'Principal Remittance Amount' means, with respect to any Distribution Date
and each Loan Group, the excess, if any, of (i) the Basic Principal Amount for
such Loan Group over (ii) the Overcollateralization Release Amount for the
related Certificate Group.
 
     The 'Remittance Period' with respect to any Distribution Date is the period
commencing on the second day of the month preceding the month in which the
Distribution Date occurs and ending on the first day of the month in which such
Distribution Date occurs.
 
     '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, after giving effect
to any previous partial principal prepayments and Liquidation Proceeds allocable
to principal and to the payment of principal due on such Due Date and
irrespective of any delinquency payment by the related Mortgagor.
 
     'Total Monthly Excess Spread' as to either Loan Group and any Distribution
Date equals the excess, if any, of (x) the interest collected or advanced for
such Loan Group in the related Remittance Period over (y) the amounts paid
pursuant to clauses (i) through (v) above with respect to the related
Certificate Group.
 
                                      S-29
 <PAGE>
<PAGE>
     'Unpaid Interest Amounts' for any Class of Certificates and any
Distribution Date will equal the sum of (a) the excess of (i) the sum of the
Class Optimal Interest Distribution Amount for such Distribution Date and any
portion of such Class Optimal Interest Distribution Amount from prior
Distribution Dates remaining unpaid over (ii) the amount in respect of interest
on such Class of Certificates actually distributed on the preceding Distribution
Date and (b) 30 days' interest on such excess at the applicable Pass-Through
Rate (to the extent permitted by applicable law).
 
     In the event that, on a particular Distribution Date, amounts applied in
the order described above 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.
 
THE POLICY
 
     The following summary of the terms of the Policy does not purport to be
complete and is qualified in its entirety by reference to the Policy. A form of
the Policy may be obtained, upon request, from the Depositor.
 
     Simultaneously with the issuance of the Offered Certificates, the
Certificate Insurer will deliver the Policy to the Trustee for the benefit of
the holders of the Offered Certificates. Under the Policy, the Certificate
Insurer will irrevocably and unconditionally guarantee payment to the Trustee on
behalf of the holders of the Offered Certificates on each Distribution Date for
the benefit of the holders of the Offered Certificates and on behalf of the
holders of the Class R Certificates on the first Distribution Date for the
benefit of the holders of the Class R Certificates, the full and complete
payment of Guaranteed Distributions with respect to the Offered Certificates
calculated in accordance with the original terms of the Offered Certificates
when issued and without regard to any amendment or modification of the Offered
Certificates or the Agreement except amendments or modifications to which the
Certificate Insurer has given its prior written consent. 'Guaranteed
Distributions' shall mean, with respect to the related Class A Certificates as
of any Distribution Date and with respect to the Class R Certificates as of the
first Distribution Date, the sum of (i) any shortfall in amounts available in
the Distribution Account (as defined in the Agreement) to pay the Class Optimal
Interest Distribution Amount on such Certificates for the related Accrual
Period, (ii) the excess, if any, of (a) the aggregate Certificate Principal
Balance of the Offered Certificates then outstanding over (b) the aggregate
principal balances of the Mortgage Loans then outstanding and (iii) without
duplication of the amount specified in clause (ii), the aggregate Certificate
Principal Balance of the Class A Certificates to the extent unpaid on the final
Distribution Date or the earlier termination of the Trust pursuant to the terms
of the Agreement. Notwithstanding the foregoing, the Certificate Insurer has the
right to pay a Realized Loss if the Overcollateralization Deficiency Amount is
zero. Guaranteed Distributions do not include distributions of principal or
interest on the Class R Certificates after the first Distribution Date and, with
respect to the Offered Certificates, reductions in the amount of monthly
interest payments on the Mortgage Loans pursuant to the Soliders' and Sailors'
Civil Relief Act of 1940.
 
     If any Guaranteed Distribution is avoided as a preference payment under
applicable bankruptcy, insolvency, receivership or similar law, the Certificate
Insurer will pay such amount out of funds of the Certificate Insurer on the
later of (a) the date when due to be paid pursuant to the Order referred to
below or (b) the first to occur of (i) the fourth Business Day following Receipt
by the Certificate Insurer from the Trustee of (A) a certified copy of the order
of the court or other governmental body which exercised jurisdiction to the
effect that a holder of Offered Certificates is required to return principal or
interest distributed with respect to an Offered Certificate during the Term of
the Policy because such distributions were avoidable preferences under
applicable bankruptcy law (the 'Order'), (B) a certificate of such holder of
Offered Certificates that the Order has been entered and is not subject to any
stay, and (C) an assignment duly executed and delivered by such holder of
Offered Certificates, in such form as is reasonably required by the Certificate
Insurer and provided to such holder of Offered Certificates by the Certificate
Insurer, irrevocably assigning to the Certificate Insurer all rights and claims
of such holder of Offered Certificates relating to or arising under the Offered
Certificates against the debtor which made such preference payment or otherwise
with respect to such preference payment, or (ii) the date of Receipt by the
Certificate Insurer from the Trustee of the items referred to in clauses (A),
(B) and (C)
 
                                      S-30
 <PAGE>
<PAGE>
above if, at least four Business Days prior to such date of Receipt, the
Certificate Insurer shall have Received written notice from the Trustee that
such items were to be delivered on such date and such date was specified in such
notice. Such payment shall be disbursed to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order and not to the
Trustee or holder of Offered Certificates directly, unless a holder of Offered
Certificates has previously paid such amount to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order, in which case
such payment shall be disbursed to the Trustee for distribution to such holder
of the Offered Certificates upon proof of such payment reasonably satisfactory
to the Certificate Insurer. In connection with the foregoing, the Certificate
Insurer shall have the rights provided pursuant to the Agreement.
 
     Payment of claims under the Policy made in respect of Guaranteed
Distributions will be made by the Certificate Insurer following Receipt by the
Certificate Insurer of the appropriate notice for payment on the later to occur
of (a) 12:00 noon, New York City time, on the second Business Day following
Receipt of such notice for payment, and (b) 12:00 noon, New York City time, on
the relevant Distribution Date.
 
     The terms 'Receipt' and 'Received', with respect to the Policy, means
actual delivery to the Certificate Insurer and to its fiscal agent appointed by
the Certificate Insurer at its option, if any, prior to 12:00 p.m., New York
City time, on a Business Day; delivery either on a day that is not a Business
Day or after 12:00 p.m., New York City time, shall be deemed to be Receipt on
the next succeeding Business Day. If any notice or certificate given under the
Policy by the Trustee is not in proper form or is not properly completed,
executed or delivered, it shall be deemed not to have been Received, and the
Certificate Insurer or the fiscal agent shall promptly so advise the Trustee and
the Trustee may submit an amended notice.
 
     Under the Policy, 'Business Day' means any day other than (i) a Saturday or
Sunday or (ii) a day on which banking institutions in the City of New York, New
York, the State of New York or in the city in which the corporate trust office
of the Trustee is located, are authorized or obligated by law or executive order
to be closed. The Certificate Insurer's obligations under the Policy to make
Guaranteed Distributions shall be discharged to the extent funds are transferred
to the Trustee as provided in the Policy, whether or not such funds are properly
applied by the Trustee.
 
     'Term of the Policy' means the period from and including the date of
issuance of the Policy to and including the date on which the Certificate
Principal Balances of the Offered Certificates are reduced to zero, plus such
additional period, to the extent specified in the Policy, during which any
payment on the Offered Certificates could be avoided in whole or in part as a
preference payment.
 
     The Certificate Insurer shall be subrogated to the rights of the holders of
the Offered Certificates to receive payments on principal and interest, as
applicable, with respect to distributions on such Certificates to the extent of
any payment by the Certificate Insurer under the Policy. To the extent the
Certificate Insurer makes Guaranteed Distributions, either directly or
indirectly (as by paying through the Trustee), to the holders of the Offered
Certificates, the Certificate Insurer will be subrogated to the rights of the
holders of the Offered Certificates, as applicable, with respect to such
Guaranteed Distributions and shall be deemed to the extent of the payments so
made to be a registered holder of the Offered Certificates for purposes of
payment.
 
     Claims under the Policy constitute direct unsecured and unsubordinated
obligations of the Certificate Insurer, and will rank not less than pari passu
with any other unsecured and unsubordinated indebtedness of the Certificate
Insurer except for certain obligations in respect to tax and other payments to
which preference is or may become afforded by statute. The terms of the Policy
cannot be modified, altered or affected by any other agreement or instrument, or
by the merger, consolidation or dissolution of the Depositor. The Policy by its
terms may not be canceled or revoked prior to distribution in full of all
Guaranteed Distributions (as defined therein). The Policy is governed by the
laws of the State of New York. The Policy is not covered by the
property/casualty insurance security fund specified in Article 76 of the New
York Insurance Law.
 
     To the fullest extent permitted by applicable law, the Certificate Insurer
agrees under the Policy not to assert, and waives, for the benefit of each
holder of the Offered Certificates, all its rights (whether by counterclaim,
setoff or otherwise) and defenses (including, without limitation, the defense of
fraud), whether acquired by subrogation, assignment or otherwise, to the extent
that such rights and defenses may be available to the Certificate Insurer to
avoid payment of its obligations under the Policy in accordance with the express
provisions of the Policy.

     Pursuant to the terms of the Agreement, unless an Insurer Default exists,
the Certificate Insurer will be entitled to exercise certain rights of the
holders of the Offered Certificates, without the consent of such
Certificateholders, and the holders of the Offered Certificates may exercise
such rights only with the prior written consent of the Certificate Insurer.
 
     The Depositor, the Seller and Master Servicer and the Certificate Insurer
will enter into an Insurance and Indemnity Agreement (the 'Insurance Agreement')
pursuant to which the Depositor and the Seller and Master Servicer will agree to
reimburse the Certificate Insurer for amounts paid pursuant to claims under the
Policy. The Depositor and the Seller and Master Servicer will further agree to
pay the Certificate Insurer all reasonable charges and expenses which the
Certificate Insurer may pay or incur relative to any amounts paid under the
Policy or otherwise in connection with the transaction and to indemnify the
Certificate Insurer against certain liabilities. Notwithstanding the foregoing,
unless otherwise specifically provided in the Insurance Agreement, the
Certificate Insurer's right to reimbursement under the Insurance Agreement shall
be a non-recourse obligation of the Depositor and the Seller and Master Servicer
and shall be payable solely from amounts available for such purpose under the
Agreement. An event of default by the Seller or the Master Servicer under the
Insurance Agreement will constitute an Event of Default by the Master Servicer
under the Agreement and allow the Certificate Insurer, among other things, to
direct the Trustee to terminate the Master Servicer.
 
THE CERTIFICATE INSURER
 
     The following information set forth in this section has been provided by
Financial Security. Accordingly, none of the Depositor, the Master Servicer or
the Underwriters makes any representation as to the accuracy and completeness of
such information.
 
     General.  Financial Security Assurance Inc. (the 'Certificate Insurer' or
'Financial Security') is a monoline insurance company incorporated in 1984 under
the laws of the State of New York. The Certificate Insurer is licensed to engage
in the financial guaranty insurance business in all 50 states, the District of
Columbia and Puerto Rico.
 
     Financial Security and its subsidiaries are engaged in the business of
writing financial guaranty insurance, principally in respect of securities
offered in domestic and foreign markets. In general, financial guaranty
insurance consists of the issuance of a guaranty of scheduled payments of an
issuer's securities -- thereby enhancing the credit rating of those
securities -- in consideration for the payment of a premium to the insurer.
Financial Security and its subsidiaries principally insure asset-backed,
collateralized and municipal securities. Asset-backed securities are generally
supported by residential mortgage loans, consumer or trade receivables,
securities or other assets having an ascertainable cash flow or market value.
Collateralized securities include public utility first mortgage bonds and
sale/leaseback obligation bonds. Municipal securities consist largely of general
obligation bonds, special revenue bonds and other special obligations of state
and local governments. Financial Security insures both newly issued securities
sold in the primary market and outstanding securities sold in the secondary
market that satisfy Financial Security's underwriting criteria.
 
     Financial Security is a wholly owned subsidiary of Financial Security
Assurance Holdings Ltd. ('Holdings'), a New York Stock Exchange listed company.
Major shareholders of Holdings include Fund American Enterprises Holdings, Inc.,
MediaOne Capital Corporation, the Tokio Marine and Fire Insurance Co., Ltd. and
XL Capital Ltd. No shareholder of Holdings is obligated to pay any debt of
Financial Security or any claim under any insurance policy issued by Financial
Security or to make any additional contribution to the capital of Financial
Security.
 
     The principal executive offices of Financial Security are located at 350
Park Avenue, New York, New York 10022, and its telephone number at that location
is (212) 826-0100.
 
     Reinsurance.  Pursuant to an intercompany agreement, liabilities on
financial guaranty insurance written or reinsured from third parties by
Financial Security or any of its domestic or Bermuda operating insurance company
subsidiaries are generally reinsured among such companies on an agreed-upon
percentage substantially proportional to their respective capital, surplus and
reserves, subject to applicable statutory risk limitations. In addition,
Financial Security reinsures a portion of its liabilities under certain of its
financial guaranty insurance policies with other reinsurers under various
treaties and on a transaction-by-transaction basis. Such reinsurance is utilized
by Financial Security as a risk management device and to comply with certain
statutory and rating

agency requirements; it does not alter or limit Financial Security's obligations
under any financial guaranty insurance policy.
 
     Ratings.  Financial Security's insurance financial strength is rated 'Aaa'
by Moody's. Financial Security's insurer financial strength is rated 'AAA' by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. and Standard &
Poor's, (Australia) Pty. Ltd. Financial Security's claims-paying ability is
rated 'AAA' by Fitch IBCA, Inc. and Japan Rating and Investment Information,
Inc. Such ratings reflect only the views of the respective rating agencies, are
not recommendations to buy, sell or hold securities and are subject to revision
or withdrawal at any time by such rating agencies.

Financial Security and its wholly owned subsidiaries on the basis of generally
accepted accounting principles as of September 30, 1998, as well as such

     Insurance Regulation.  The Certificate Insurer is licensed and subject to
regulation as a financial guaranty insurance corporation under the laws of the
State of New York, its state of domicile. In addition, the Certificate Insurer
and its insurance subsidiaries are subject to regulation by insurance laws of
the various other jurisdictions in which they are licensed to do business. As a
financial guaranty insurance corporation licensed to do business in the State of
New York, the Certificate Insurer is subject to Article 69 of the New York
Insurance Law which, among other things, limits the business of each such
insurer to financial guaranty insurance and related lines, requires that each
such insurer maintain a minimum surplus to policyholders, establishes
contingency, loss and unearned premium reserve requirements for each such
insurer, and limits the size of individual transactions ('single risks') and the
volume of transactions ('aggregate risks') that may be underwritten by each such
insurer. Other provisions of the New York Insurance Law, applicable to non-life
insurance companies such as the Certificate Insurer, regulate, among other
things, permitted investments, payment of dividends, transactions with
affiliates, mergers, consolidations, acquisitions or sales of assets and
incurrence of liability for borrowings.
 
CERTAIN MATTERS REGARDING THE CERTIFICATE INSURER
 
     Pursuant to the terms of the Agreement, unless there exists a continuance
of any failure by the Certificate Insurer to make a required payment under the
Policy or there exists a proceeding in bankruptcy by or against the Certificate
Insurer (either such condition, a 'Certificate Insurer Default'), the
Certificate Insurer will be entitled to exercise, among others, the following
rights of the holders of the Offered Certificates, without the consent of such
holders, and the holders of the Offered Certificates may exercise such rights
only with the prior written consent of the Certificate Insurer: (i) the right to
direct the Trustee to terminate the rights and obligations of the Master
Servicer under the Agreement in the event of a default by such Master Servicer;
(ii) the right to consent to or direct any waivers of defaults by the Master
Servicer; (iii) the right to remove the Trustee pursuant to the Agreement; and
(iv) the right to institute proceedings against the Master Servicer in the event
of default by the Master Servicer and refusal of the Trustee to institute such
proceedings. In addition, unless a Certificate Insurer Default exists, the
Certificate Insurer will have the right to direct all matters relating to any
proceeding seeking the avoidance as a preferential transfer under applicable
bankruptcy, insolvency, receivership or similar law of any distribution made
with respect to the Offered Certificates, and, unless an Certificate Insurer
Default exists, the Certificate Insurer's consent will be required prior to,
among other things, (i) the removal of the Trustee, (ii) the appointment of any
successor Trustee or Master Servicer, as the case may be, or (iii) any amendment
to the Agreement.

CALCULATION OF ONE-MONTH LIBOR
 
     On each LIBOR Determination Date (as defined below), the Trustee will
determine One-Month LIBOR for the next Interest Accrual Period for the Group 2
Certificates.
 
     'One-Month LIBOR' means, as of any LIBOR Determination Date, the London
interbank offered rate for one-month United States dollar deposits which appears
in the Telerate Page 3750 as of 11:00 a.m., London time, on such date. If such
rate does not appear on Telerate Page 3750, the rate for that day will be
determined on the basis of the rates at which deposits in United States dollars
are offered by the Reference Banks at approximately 11:00 a.m. (London time), on
that day to prime banks in the London interbank market. The Trustee will request
the principal London office of each of the Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that day will be the arithmetic mean of the quotations (rounded upwards if
necessary to the nearest whole multiple of 1/16%). If fewer than two quotations
are provided as requested, the rate for that day will be the arithmetic mean of
the rates quoted by major banks in New York City, selected by the Master
Servicer, at approximately 11:00 a.m. (New York City time) on that day for loans
in United States dollars to leading European banks.
 
     'LIBOR Determination Date' means, with respect to any Interest Accrual
Period, the second London business day preceding the commencement of such
Interest Accrual Period. For purposes of determining One-Month LIBOR, a 'London
business day' is any day on which dealings in deposits of United States dollars
are transacted in the London interbank market.
 
     'Telerate Page 3750' means the display page currently so designated on the
Bridge Telerate Service (or such other page as may replace that page on that
service for the purpose of displaying comparable rates or prices) and 'Reference
Banks' means leading banks selected by the Master Servicer and engaged in
transactions in Eurodollar deposits in the international Eurocurrency market.
 
OVERCOLLATERALIZATION PROVISIONS
 
     The Agreement requires that the Total Monthly Excess Spread, if any, with
respect to each Loan Group on each Distribution Date (or in the case of the
first Distribution Date, 50% of the Total Monthly Excess Spread) be applied as
an accelerated payment of principal of the Class A Certificates of the related
Certificate Group, but only to the limited extent hereafter described.
 
     The application of Total Monthly Excess Spread to the payment of principal
of the Class A Certificates in a Certificate Group has the effect of
accelerating the amortization of such Certificates relative to the amortization
of the related Mortgage Loans. The portion, if any, of the Available Funds not
required to be distributed to holders of the Offered Certificates as described
above on any Distribution Date will be paid to the holders of the Class OC
Certificates and will not be available on any future Distribution Date to cover
Principal Distribution Amount or Unpaid Interest Amounts.
 
STRUCTURING ASSUMPTIONS
 
     The model used in this Prospectus Supplement (the 'Prepayment Assumption')
represents an assumed rate of prepayment each month relative to the then
outstanding principal balance of a pool of mortgage loans for the life of such
mortgage loans. 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 related Mortgage Loans.
With respect to the Mortgage Loans in Loan Group 1, a 100% Prepayment Assumption
assumes conditional prepayment rates of 5% per annum of the then outstanding
principal balance of the Mortgage Loans in Loan Group 1 in the first month of
the life of the related Mortgage Loans and an additional 1.818182% per annum
(or, more precisely, 20/11%) in each month thereafter until the twelfth month.
Beginning in the twelfth month and in each month thereafter during the life of
the Mortgage Loans in Loan Group 1, 100% Prepayment Assumption assumes a
conditional prepayment rate of 25% per annum each month. As used in the table
below, 0% Prepayment Assumption assumes prepayment rates equal to 0% of the
Prepayment Assumption i.e., no prepayments. Correspondingly, 100% Prepayment
Assumption assumes prepayment rates equal to 100% of the Prepayment Assumption,
and so forth. The Prepayment Assumption with respect to Loan Group 2, assumes a
Constant Prepayment Rate ('CPR').
 
     Since the tables were prepared on the basis of the assumptions in the
following paragraph, there are discrepancies between the characteristics of the
actual Mortgage Loans and the characteristics of the Mortgage
 
                                      S-35
 <PAGE>
<PAGE>
Loans assumed in preparing the tables. Any such discrepancy may have an effect
upon the percentages of the Certificate Principal Balances outstanding and
weighted average lives of the Offered Certificates set forth in the tables. In
addition, since the actual Mortgage Loans in the Trust have characteristics
which differ from those assumed in preparing the tables set forth below, the
distributions of principal on the Offered Certificates may be made earlier or
later than as indicated in the tables.
 
     Unless otherwise specified, the information in the tables in this
Prospectus Supplement has been prepared on the basis of the following assumed
characteristics of the Mortgage Loans and the following additional assumptions
(collectively, the 'Structuring Assumptions'): (i) the Mortgage Loans of each
Loan Group which consist of pools of loans with level-pay or balloon
amortization methodologies, Cut-off Date Principal Balances, mortgage rates,
original and remaining terms to maturity, and original amortization terms, as
applicable, are as set forth below, (ii) the Closing Date for the Certificates
occurs on March 30, 1999, (iii) distributions on the Certificates are made on
the 25th day of each month, commencing on April 25, 1999, in accordance with the
priorities described herein, (iv) the Mortgage Loans' prepayment rates with
respect to the Mortgage Loans in Loan Group 1 are a multiple of the applicable
Prepayment Assumption and with respect to the Mortgage Loans in Loan Group 2 are
constant percentages of CPR each as stated in the 'Prepayment Scenarios' table
below; (v) prepayments include 30 days' interest thereon, (vi) no optional
termination or mandatory termination is exercised (unless otherwise specified),
(vii) with respect to Mortgage Loan Group 2, (a) the Mortgage Rate for each
Mortgage Loan is adjusted on its next rate adjustment date (and on subsequent
adjustment dates, if necessary) to a rate equal to the Gross Margin plus the
Index (such sum being subject to the applicable periodic adjustment cap and
maximum interest rate), (b) the assumed level of the Index is 5.06375% and (c)
the scheduled monthly payment on the Mortgage Loans is adjusted to equal a fully
amortizing payment, (viii) One-Month LIBOR remains constant at 4.93875%, (ix) no
defaults in the payment by Mortgagors of principal of and interest on the
Mortgage Loans are experienced, (x) scheduled payments on the Mortgage Loans are
received on the first day of each month commencing in the calendar month of the
Closing Date and are computed prior to giving effect to prepayments received on
the last day of the prior month, (xi) prepayments represent prepayments in full
of individual Mortgage Loans and are received on the last day of each month,
commencing in the calendar month prior to the Closing Date, (xii) the initial
Class Certificate Balance of each Class of Certificates is as set forth on the
cover page hereof, and (xiii) interest accrues on each Class of Certificates at
the applicable interest rate set forth or described on the cover hereof. While
it is assumed that each of the Mortgage Loans prepays at the specified constant
percentages of the Prepayment Assumption, this is not likely to be the case.
Moreover, discrepancies exist between the characteristics of the actual Mortgage
Loans which will be delivered to the Trustee and characteristics of the Mortgage
Loans assumed in preparing the tables herein.

OPTIONAL PURCHASE OF DEFAULTED LOANS
 
     The Master Servicer may, at its option, purchase from the Trust Fund any
Mortgage Loan which is delinquent in payment by 91 days or more; provided that
the aggregate Stated Principal Balance of all Mortgage Loans purchased by the
Master Servicer pursuant to this provision shall not exceed the level specified
in the Agreement without the Certificate Insurer's consent. 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 or
advanced (and not reimbursed) to the first day of the month in which such amount
is to be distributed.
 
OPTIONAL TERMINATION
 
     The Master Servicer will have the right to repurchase all remaining
Mortgage Loans and REO Properties and thereby effect early retirement of the
Certificates, subject to the Stated Principal Balance of the Mortgage Loans and
REO Properties at the time of repurchase being less than or equal to 10% of the
Cut-off Date Principal Balance (as the 'Optional Termination Date'). Any such
purchase of Mortgage Loans requires the consent of the Certificate Insurer if it
(i) would result in the failure of the Certificate Insurer to receive amounts
due under the Insurance Agreement or (ii) would result in a draw on the Policy.
In the event the Master Servicer exercises such option, the purchase price
distributed with respect to the Certificates will be 100% of its then
outstanding principal balance and any unpaid accrued interest thereon at the
applicable Pass-Through Rate (in each case subject to reduction as provided in
the Agreement if the purchase price is based in part on the appraised value of
any REO Properties and such appraised value is less than the Stated Principal
Balance of the Mortgage Loans). Distributions on the Certificates in respect of
any such optional termination will first be paid as set forth under 'Description
of the Certificates -- Distributions of Interest and Principal' herein. 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.
 
THE TRUSTEE
 
     The Bank of New York will be the Trustee under the Agreement. The Depositor
and the Master Servicer may maintain other banking relationships in the ordinary
course of business with The Bank of New York. Offered Certificates may be
surrendered at the Corporate Trust Office of the Trustee located at 101 Barclay
Street, 12E, New York, New York 10286, Attention: Corporate Trust Administration
or at such other addresses as the Trustee may designate from time to time.
 
RESTRICTIONS ON TRANSFER OF THE CLASS R CERTIFICATES
 
     The Class R Certificates will be subject to the restrictions on transfer
described in the Prospectus under 'Federal Income Tax Consequences -- Taxation
of Holders of Residual Interest Securities -- Restrictions on Ownership and
Transfer of Residual Interest Securities.' The Agreement provides that the
Class R Certificates (in addition to certain other Classes of Certificates) may
not be acquired by an ERISA Plan. See 'ERISA Considerations' herein. Each Class
R Certificate will contain a legend describing the foregoing restrictions.

                 YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS
 
GENERAL
 
     The effective yields to the holders of the Fixed Rate 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
until the 25th day (or, if 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).
 
     Each Interest Accrual Period for the Adjustable Rate Certificates will
consist of the actual number of days elapsed from the Distribution Date in the
month preceding the month of the applicable Distribution Date (or, in the case
of the first Interest Accrual Period, from the Closing Date) through the day
preceding such Distribution Date.
 
DEFAULTS
 
     The yield to maturity of the Offered Certificates will be sensitive to
defaults on the Mortgage Loans in the related Loan Group. If a purchaser of an
Offered Certificate calculates its anticipated yield based on an assumed rate of
default and amount of losses that is lower than the default rate and amount of
losses actually incurred, its actual yield to maturity will be lower than that
so calculated. Holders of the Offered Certificates may not receive reimbursement
for Realized Losses in the month following the occurrence of such losses. In
general, the earlier a loss occurs, the greater is the effect on an investor's
yield to maturity. There can be no assurance as to the delinquency, foreclosure
or loss experience with respect to the Mortgage Loans. Because the Mortgage
Loans were underwritten in accordance with standards less stringent than those
generally acceptable to FNMA and FHLMC with regard to a borrower's credit
standing and repayment ability, the risk of delinquencies with respect to, and
losses on, the Mortgage Loans will be greater than that of mortgage loans
underwritten in accordance with FNMA and FHLMC standards.
 
     In general, a 'Realized Loss' means, 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. A 'Liquidated Mortgage Loan' is a defaulted
Mortgage Loan as to which the Master Servicer has determined that all
recoverable liquidation and insurance proceeds have been received.
 
PREPAYMENT CONSIDERATIONS AND RISKS
 
     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. 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 or condemnations
and repurchases by the Seller or Master Servicer). Because certain of the
Mortgage Loans contain prepayment penalties, the rate of principal payments may
be less than the rate of principal payments for mortgage loans which did not
have prepayment penalties. The fixed-rate Mortgage Loans are subject to the
'due-on-sale' provisions included therein. See 'The Mortgage Pool' herein.
 
     Prepayments, liquidations and purchases of the Mortgage Loans in a Loan
Group (including any optional purchase by the Master 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 in 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. Further, an investor should consider the risk that, in
the case of any Offered Certificate
 
                                      S-38
 <PAGE>
<PAGE>
purchased at a discount, a slower than anticipated rate of principal payments
(including prepayments) on the Mortgage Loans in the related Loan Group could
result in an actual yield to such investor that is lower than the anticipated
yield and, in the case of any Offered Certificate purchased at a premium, a
faster than anticipated rate of principal payments on the Mortgage Loans in the
related Loan Group could result in an actual yield to such investor that is
lower than the anticipated yield.
 
     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. In general, if prevailing interest
rates were to fall significantly below the Mortgage Rates on the Mortgage Loans
in Loan Group 1, such Mortgage Loans could be subject to higher prepayment rates
than if prevailing interest rates were to remain at or above the Mortgage Rates
on such Mortgage Loans. Conversely, if prevailing interest rates were to rise
significantly, the rate of prepayments on the Mortgage Loans in Loan Group 1
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.
 
     All of the Mortgage Loans in Loan Group 2 are ARMs. As is the case with
fixed rate Mortgage Loans, the ARMs may be subject to a greater rate of
principal prepayments in a low interest rate environment. For example, if
prevailing interest rates were to fall, Mortgagors with ARMs may be inclined to
refinance their ARMs with a fixed rate loan to 'lock in' a lower interest rate.
The existence of the applicable Periodic Rate Cap and Maximum Rate also may
affect the likelihood of prepayments resulting from refinancings. In addition,
the delinquency and loss experience of the ARMs may differ from that on the
fixed rate Mortgage Loans because the amount of the monthly payments on the ARMs
are subject to adjustment on each Adjustment Date. In addition, a substantial
majority of the ARMs (the 2/28 Adjustable Mortgage Loans, the 3/27 Adjustable
Mortgage Loans and the 3/1 Adjustable Mortgage Loans) will not have their
initial Adjustment Date until 2 or 3 years after the origination thereof. The
prepayment experience of the 2/28 Adjustable Mortgage Loans, the 3/27 Adjustable
Mortgage Loans and the 3/1 Adjustable Mortgage Loans may differ from that of the
other ARMs. The 2/28 Adjustable Mortgage Loans, the 3/27 Adjustable Mortgage
Loans and the 3/1 Adjustable Mortgage Loans may be subject to greater rates of
prepayments as they approach their initial Adjustment Dates even if market
interest rates are only slightly higher or lower than the Mortgage Rates on the
2/28 Adjustable Mortgage Loans, the 3/27 Adjustable Mortgage Loans or the 3/1
Adjustable Mortgage Loans (as the case may be) as borrowers seek to avoid
changes in their monthly payments.
 
     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.
 
ADJUSTABLE RATE CERTIFICATES
 
     Each Interest Accrual Period for the Adjustable Rate Certificates will
consist of the actual number of days elapsed from the preceding Distribution
Date (or, in the case of the first Distribution Date, from the Closing Date)
through the day preceding the applicable Distribution Date. The Pass-Through
Rate for the Adjustable Rate Certificates will be adjusted by reference to
One-Month LIBOR, subject to the effects of the applicable limitations described
herein.
 
     The Pass-Through Rate for the Adjustable Rate Certificates may be
calculated by reference to the Net Mortgage Rates of the Mortgage Loans in Loan
Group 2, which are based on the Index. If the Mortgage Loans bearing higher
Mortgage Rates, either through higher margins or an increase in the Index (and
consequently, higher Adjusted Net Mortgage Rates), were to prepay, the weighted
average Adjusted Net Mortgage Rate would be lower than otherwise would be the
case. Changes in One-Month LIBOR may not correlate with changes in the Index. It
is possible that a decrease in the Index, which would be expected to result in
faster prepayments, could occur simultaneously with an increased level of
One-Month LIBOR. If the sum of One-Month LIBOR plus the Pass-Through Margin for
the Adjustable Rate Certificates were to be higher than the Group 2 WAC
 
                                      S-39
 <PAGE>
<PAGE>
Cap, the Pass-Through Rate on the Adjustable Rate Certificates would be lower
than otherwise would be the case.
 
OVERCOLLATERALIZATION PROVISIONS
 
     The operation of the overcollateralization provisions of the Agreement will
affect the weighted average lives of the Offered Certificates and consequently
the yields to maturity of such Certificates. Unless and until the
Overcollateralized Amount for a Loan Group equals or exceeds the
Overcollateralization Target Amount for such Loan Group, Total Monthly Excess
Spread will be applied as distributions of principal of the Class A Certificates
in the related Certificate Group, thereby reducing the weighted average lives
thereof. The actual Overcollateralized Amount for a Loan Group may change from
Distribution Date to Distribution Date producing uneven distributions of Total
Monthly Excess Spread. In addition, the Overcollateralization Target Amount for
a Loan Group may increase or decrease based on the delinquency and loss
experience on the related Mortgage Loans. There can be no assurance as to when
or whether the Overcollateralized Amount for a Loan Group will equal or exceed
the Overcollateralization Target Amount for such Loan Group.
 
     Total Monthly Excess Spread generally is a function of the excess of
interest collected or advanced on the Mortgage Loans over the interest required
to pay interest on the Offered Certificates and expenses at the Expense Rate.
Mortgage Loans with higher Adjusted Net Mortgage Rates (as defined below) will
contribute more interest to the Total Monthly Excess Spread. Mortgage Loans with
higher Adjusted Net Mortgage Rates may prepay faster than Mortgage Loans with
relatively lower Adjusted Net Mortgage Rates in response to a given change in
market interest rates. Any such disproportionate prepayments of Mortgage Loans
with higher Adjusted Net Mortgage Rates may adversely affect the amount of Total
Monthly Excess Spread available to make accelerated payments of principal of the
Offered Certificates in the related Certificate Group. 'Adjusted Net Mortgage
Rate' means, as to any Mortgage Loan and Distribution Date, the related Mortgage
Rate as of the Due Date in the month preceding the month of such Distribution
Date reduced by the related Expense Fee Rate.
 
     As a result of the interaction of the foregoing factors, the effect of the
overcollateralization provisions on the weighted average lives of the Offered
Certificates may vary significantly over time and from Class to Class.
 
ADDITIONAL INFORMATION
 
     The Depositor will file certain yield tables and other computational
materials with respect to certain Classes of the Offered Certificates with the
Commission in a report on Form 8-K. Such tables and materials were prepared by
the Underwriters 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.
 
WEIGHTED AVERAGE LIVES OF THE OFFERED CERTIFICATES
 
     The weighted average life of an Offered Certificate is determined by (a)
multiplying the amount of the reduction, if any, of the Class Certificate
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
Certificate Balance of such Certificate 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 and Prepayment Considerations' in
the Prospectus.
 
     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 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 -- Distributions' 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
 
                                      S-40
 <PAGE>
<PAGE>
Certificate 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 percentages of the
Prepayment Assumption, see the Decrement Tables below.
 
DECREMENT TABLES
 
     The following tables indicate the percentages of the initial Class
Certificate Balances of the Classes of Offered Certificates that would be
outstanding after each of the dates shown at various constant percentages of the
applicable Prepayment Assumption included in the Prepayment Scenarios 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 constant percentages of the applicable
Prepayment Assumption included in the Prepayment Scenarios specified in the
tables or at any other 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 specified constant percentages of the applicable
Prepayment Assumption included in the Prepayment Scenarios, even if the weighted
average remaining term to maturity of the Mortgage Loans is consistent with the
remaining terms to maturity of the Mortgage Loans specified in the Structuring
Assumptions.

LAST SCHEDULED DISTRIBUTION DATE
 
     The last scheduled distribution date (the 'Last Scheduled Distribution
Date') for each Class of Offered Certificates is the Distribution Date in April
2029, which is the Distribution Date immediately following the latest scheduled
maturity date for any of the Mortgage Loans.
 
     Since the rate of distributions in reduction of the Class Certificate
Balance of each Class of Offered Certificates will depend on the rate of payment
(including prepayments) of the related Mortgage Loans, the Class Certificate
Balance 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 and Prepayment
Considerations' in the Prospectus.
 
                                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 multiple
segregated asset pools. The Trustee will make a REMIC election with respect to
each such segregated asset pool. The Mortgage Loans and certain other property
will be held by one REMIC (the 'Initial Subsidiary REMIC'), which will issue
various classes of uncertificated interests that will be designated as regular
and residual interests. The Initial Subsidiary REMIC will be part of a tiered
REMIC structure in which the regular interests issued by one REMIC will
constitute the assets of a higher tier REMIC. The Offered Certificates (other
than the Class R Certificates), together with the Class PF, Class PV and OC
Certificates (collectively, the 'Regular Certificates'), will be designated as
regular interests in a REMIC (the 'Master REMIC'). The Class R Certificates will
evidence ownership of the residual interest in the Master REMIC and in each
Subsidiary REMIC.
 
     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 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
Mortgage Loans in each Loan Group at a rate equal to the Prepayment Assumption
relating to each Loan Group. No representation is made as to whether the
Mortgage Loans will prepay at the foregoing rates 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.
 
     The holders of the Class R 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 Class R Certificate recognized by
a holder may be treated as 'excess inclusion' income, which, with limited
exceptions, is subject to U.S. federal income tax.
 
     Prospective purchasers of a Class R Certificate should be aware that
Treasury regulations (the 'Mark-to-Market Regulations') provide that a Class R
Certificate cannot be marked-to-market. The Mark-to-Market Regulations change
the temporary regulations discussed in the Prospectus which allowed a Class R
Certificate to
 
                                      S-43
 <PAGE>
<PAGE>
be marked-to-market provided that it was not a 'negative value' residual
interest and did not have the same economic effect as a 'negative value'
residual interest. Also, purchasers of a Class R 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 'Federal Income Tax Consequences -- Taxation
of Holders of Residual Interest Securities' in the Prospectus. Specifically,
prospective holders of Class R Certificates should consult their tax advisors
regarding whether, at the time of acquisition, a Class R Certificate will be
treated as a 'noneconomic' residual interest, a 'non-significant value' residual
interest and a 'tax avoidance potential' residual interest. See 'Federal Income
Tax Consequences -- Taxation of Holders of Residual Interest
Securities -- Restrictions on Ownership,  -- Transfer of Residual Interest
Securities,  -- Mark-to-Market Rules and -- Excess Inclusions' in the
Prospectus. Additionally, for information regarding Prohibited Transactions and
Treatment of Realized Losses, see 'Federal Income Tax Consequences -- Taxation
of Residual Interest Securities -- Limitation on 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 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 NationsBank Corp. (now known as Bank of America Corp.) (Prohibited
Transaction Exemption 93-31, Exemption Application No. D-9105 58 Fed. Reg. 28620
and to PaineWebber Incorporated (Prohibited Transaction Exemption 90-36)
Exemption Application No. D-8069, 55 Fed. Reg. 25903 (together, 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.
 
     On July 21, 1997, the Department of Labor adopted an amendment to the
Exemption (and the similar exemptions granted to other underwriters) which
specifically permits the establishment of a yield maintenance account within the
Trust Fund to supplement the interest rate payable to certain
certificateholders.
 
     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 Class A 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 R CERTIFICATES MAY NOT MEET THE
REQUIREMENTS OF PTCE 83-1, THE EXEMPTION OR ANY OTHER ISSUED EXEMPTION UNDER
ERISA, THE PURCHASE AND HOLDING OF THE CLASS 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 R CERTIFICATES WILL NOT BE
REGISTERED BY THE TRUSTEE UNLESS THE TRUSTEE RECEIVES (OR, IN THE CASE OF
BOOK-ENTRY CERTIFICATE, THE TRUSTEE WILL BE DEEMED TO HAVE RECEIVED THE
FOLLOWING ITEMS (I) AND/OR (II) (AS APPLICABLE) BY THE HOLDER'S ACCEPTANCE OF
SUCH BOOK-ENTRY CERTIFICATE): (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
TO ANY OBLIGATION IN ADDITION TO THOSE UNDERTAKEN IN THE AGREEMENT. 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 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 PTCE 83-1 as
described in the Prospectus and 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.

     Each Underwriter purchasing Offered Certificates from the Depositor as
specified will offer and distribute the Certificates it purchases from time to
time in negotiated transactions or otherwise at varying prices to be determined
at the time of sale. In connection with the sale of such Offered Certificates,
the Underwriters may be deemed to have received compensation from the Depositor
in the form of underwriting discounts.
 
     Each Underwriter intends to make a secondary market in each Class of the
Offered Certificates purchased by it, but neither Underwriter has any obligation
to do so. There can be no assurance that a secondary market for the Offered
Certificates will develop or, if it does develop, that it will continue or that
it will provide Certificateholders with a sufficient level of liquidity of
investment.
 
     The Depositor has agreed to indemnify the Underwriters against, or make
contributions to the Underwriters with respect to, certain liabilities,
including liabilities under the Securities Act of 1933, as amended.

                                 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. Stroock & Stroock & Lavan LLP New York,
New York, will pass upon certain legal matters on behalf of the Underwriters.
 
                                    EXPERTS
 
     The consolidated balance sheets of Financial Security Assurance Inc. and
Subsidiaries as of December 31, 1997 and 1996 and the related consolidated
statements of income, changes in shareholder's equity, and cash flows for each
of the three years in the period ended December 31, 1997, incorporated by
reference in this Prospectus Supplement, have been incorporated herein in
reliance on the report of PricewaterhouseCoopers LLP, independent accountants,
given on the authority of that firm as experts in accounting and auditing.
 
                                    RATINGS
 
     It is a condition to the issuance of the Offered Certificates that they be
rated AAA by S&P and Aaa by Moody's (S&P and Moody's, the 'Rating Agencies').
 
     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 an '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 assigned by Moody's 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. The 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. The
ratings assigned by Moody's do not address the effect on the certificates' yield
attributable to prepayments or recoveries on the underlying mortgage loans. The
rating assigned by Moody's to the Class R Certificates only addresses the return
of its Class Certificate Balance and interest thereon at its Pass-Through Rate.
 
     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.

                               INDYMAC ABS, INC.
                                   Depositor
                           Asset Backed Certificates
                               Asset Backed Notes
                              (Issuable in Series)
                         ------------------------------
 
    This Prospectus relates to the issuance of Asset Backed Certificates (the
'Certificates') and Asset Backed Notes (the 'Notes' and, together with the
Certificates, the 'Securities'), which may be sold from time to time in one or
more series (each, a 'Series') by IndyMac ABS, Inc. (the 'Depositor') or by a
Trust Fund (as defined below) on terms determined at the time of sale and
described in this Prospectus and the related Prospectus Supplement. The
Securities of a Series will consist of Certificates which evidence beneficial
ownership of a trust established by the Depositor (each, a 'Trust Fund'), and/or
Notes secured by the assets of a Trust Fund. As specified in the related
Prospectus Supplement, the Trust Fund for a Series of Securities will include
certain assets (the 'Trust Fund Assets') which will consist of the following
types of mortgage loans (the 'Loans'): (i) mortgage loans secured by first
and/or subordinate liens on one- to four-family residential properties,
including manufactured housing that is permanently affixed and treated as real
property under local law, or security interests in shares issued by cooperative
housing corporations (the 'Single Family Loans'), (ii) mortgage loans secured by
first and/or subordinate liens on small multifamily residential properties, such
as rental apartment buildings or projects containing five to fifty residential
units (the 'Multifamily Loans'), (iii) closed-end and/or revolving home equity
loans (the 'Home Equity Loans'), secured in whole or in part by first and/or
subordinate liens on one- to four-family residential properties and (iv) home
improvement installment sale contracts and installment loan agreements (the
'Home Improvement Contracts') that are either unsecured or secured by first or
subordinate liens on one- to four-family residential properties, or by purchase
money security interests in the home improvements financed thereby (the 'Home
Improvements'). The Trust Fund Assets will be acquired by the Depositor, either
directly or indirectly, from one or more institutions (each, a 'Seller'), which
may be affiliates of the Depositor, and conveyed by the Depositor to the related
Trust Fund. A Trust Fund also may include insurance policies, surety bonds, cash
accounts, reinvestment income, guaranties or letters of credit to the extent
described in the related Prospectus Supplement. See 'Index of Defined Terms' on
Page 99 of this Prospectus for the location of the definitions of certain
capitalized terms.
 
    Each Series of Securities will be issued in one or more classes. Each class
of Certificates of a Series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on the related Trust Fund Assets. Each class of Notes of a Series will be
secured by the related Trust Fund Assets or, if so specified in the related
Prospectus Supplement, a portion thereof. A Series of Securities may include one
or more classes that are senior in right of payment to one or more other classes
of Securities of such Series. One or more classes of Securities of a Series may
be entitled to receive distributions of principal, interest or any combination
thereof prior to one or more other classes of Securities of such Series or after
the occurrence of specified events, in each case as specified in the related
Prospectus Supplement.

    THE CERTIFICATES OF A GIVEN SERIES WILL REPRESENT BENEFICIAL INTERESTS IN,
AND THE NOTES OF A GIVEN SERIES WILL REPRESENT OBLIGATIONS OF, THE RELATED TRUST
FUND ONLY AND WILL NOT REPRESENT INTERESTS IN OR OBLIGATIONS OF THE DEPOSITOR,
THE MASTER SERVICER, ANY SELLER OR ANY AFFILIATES THEREOF, EXCEPT TO THE EXTENT
DESCRIBED IN THE RELATED PROSPECTUS SUPPLEMENT. THE SECURITIES AND THE LOANS
WILL NOT BE INSURED OR GUARANTEED BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY

      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 OR THE RELATED PROSPECTUS SUPPLEMENT. ANY
                         REPRESENTATION TO THE CONTRARY
                               IS A CRIMINAL OFFENSE.
 
                         ------------------------------
 
    Prior to issuance there will have been no market for the Securities of any
Series and there can be no assurance that a secondary market for any Securities
will develop, or if it does develop, that it will continue or provide
Securityholders with a sufficient level of liquidity of investment. This
Prospectus may not be used to consummate sales of Securities of any Series

will be limited to its contractual servicing obligations, including any
obligation it may have to advance delinquent interest and/or principal payments
on the related Trust Fund Assets.

among other things, the rate of payments of principal (including prepayments) on
the related Trust Fund Assets and the timing of receipt of such payments as
described under 'Risk Factors -- Prepayment and Yield Considerations' and 'Yield
and Prepayment Considerations' herein and in the related Prospectus Supplement.
A Trust Fund may be subject to early termination under the circumstances
described under 'The Agreements -- Termination'; Optional Termination herein and

estate mortgage investment conduit' ('REMIC') or as a 'financial asset
securitization investment trust' ('FASIT') for federal income tax purposes. See

                                            mortgages or deeds of trust or other similar security instruments
                                            creating a lien on a Mortgaged Property (as defined below), which may
                                            be subordinated to one or more senior liens on the Mortgaged
                                            Property, as described in the related Prospectus Supplement. As
                                            specified in the related Prospectus Supplement, Home Improvement
                                            Contracts may be unsecured or secured by purchase money security
                                            interests in the Home Improvements financed thereby. If so specified
                                            in the related Prospectus Supplement, the Home Equity Loans and the
                                            Home Improvement Contracts may include Loans (primarily for home
                                            improvement or debt consolidation purposes) that are in amounts in
                                            excess of the value of the related Mortgaged Properties at the time
                                            of origination. The Mortgaged Properties and the Home Improvements
                                            are collectively referred to herein as the 'Properties'. All
                                            Properties will be located in the United States, its territories or
                                            possessions.

Description of the Securities.............  Each Security will represent a beneficial ownership interest in, or
                                            be secured by the assets of, a Trust Fund created by the Depositor
                                            pursuant to an Agreement among the Depositor, the Master Servicer and
                                            the Trustee for the related Series. The Securities of any Series may
                                            be issued in one or more classes as specified in the related
                                            Prospectus Supplement. A Series of Securities may include one or more

                                            and one or more classes of subordinate Securities (collectively, the
                                            'Subordinated Securities'). Certain Series or classes of Securities
                                            may be covered by insurance policies or other forms of credit
                                            enhancement, in each case as described under 'Credit Enhancement'
                                            herein and in the related Prospectus Supplement.

                                            subordinated in the right to receive distributions of scheduled
                                            payments of principal, prepayments of principal, interest or any
                                            combination thereof to one or more other classes of Securities of
                                            such Series throughout the lives of the Securities or during
                                            specified periods; (iv) may be entitled to receive such distributions
                                            only after the occurrence of events specified in the related

                                            allocable to interest only after the occurrence of events specified
                                            in the related Prospectus Supplement and may accrue interest until
                                            such events occur, in each case as specified in the related
                                            Prospectus Supplement. The timing and amounts of such distributions
                                            may vary among classes or over time, as specified in the related
                                            Prospectus Supplement.

Distributions on the Securities...........  Distributions on the Securities entitled thereto will be made
                                            monthly, quarterly, semi-annually or at such other intervals and on
                                            the dates specified in the related Prospectus Supplement (each, a
                                            'Distribution Date') out of the payments received in respect of the
                                            assets of the related Trust Fund or Funds or other assets pledged for
                                            the benefit of the Securities as described under 'Credit Enhancement'
                                            herein to the extent specified in the related Prospectus Supplement.
                                            The amount allocable to payments of principal and interest on any
                                            Distribution Date will be determined as specified in the related
                                            Prospectus Supplement. The Prospectus Supplement for a Series of
                                            Securities will describe the method for allocating distributions
                                            among Securities of different classes as well as the method for
                                            allocating distributions among Securities for any particular class.

                                            Unless otherwise specified in the related Prospectus Supplement, the
                                            aggregate original principal balance of the Securities will not
                                            exceed the aggregate distributions allocable to principal that such
                                            Securities will be entitled to receive. If specified in the related
                                            Prospectus Supplement, the Securities will have an aggregate original
                                            principal balance equal to the aggregate unpaid principal balance of
                                            the Trust Fund Assets as of the related Cut-off Date and will bear
                                            interest in the aggregate at a rate equal to the interest rate borne
                                            by the underlying Loans (the 'Loan Rate') net of the aggregate
                                            servicing fees and any other amounts specified in the related
                                            Prospectus Supplement, or at such other interest rate as may be
                                            specified in such Prospectus Supplement. If specified in the related
                                            Prospectus Supplement, the aggregate original principal balance of
                                            the Securities and interest rates on the classes of Securities will
                                            be determined based on the cash flow on the Trust Fund Assets.

                                            The rate at which interest will be passed through or paid to holders
                                            of each class of Securities entitled thereto may be a fixed rate or a
                                            rate that is subject to change from time to time from the time and
                                            for the periods, in each case, as specified in the related Prospectus
                                            Supplement. Any such rate may be calculated on a loan-by-loan,
                                            weighted average or notional amount in each case as described in the
                                            related Prospectus Supplement.

Credit Enhancement........................  The assets in a Trust Fund or the Securities of one or more classes
                                            in the related Series may have the benefit of one or more types of
                                            credit enhancement as described in the related Prospectus Supplement.
                                            The protection against losses afforded by any such credit support may
                                            be limited. The type, characteristics and amount of credit
                                            enhancement will be determined based on the characteristics of the
                                            Loans comprising the Trust Fund Assets and other factors and will be
                                            established on the basis of requirements of

                                            Enhancement'.

A. Subordination..........................  A Series of Securities may consist of one or more classes of Senior
                                            Securities and one or more classes of Subordinated Securities. The
                                            rights of the holders of the Subordinated Securities of a Series to
                                            receive distributions with respect to the assets in the related Trust
                                            Fund will be subordinated to such rights of the holders of the Senior
                                            Securities of the same Series to the extent described in the related
                                            Prospectus Supplement. This subordination is intended to enhance the
                                            likelihood of regular receipt by holders of Senior Securities of the
                                            full amount of monthly payments of principal and interest due them.
                                            The protection afforded to the holders of Senior Securities of a
                                            Series by means of the subordination feature will be accomplished by
                                            (i) the preferential right of such holders to receive, prior to any
                                            distribution being made in respect of the related Subordinated
                                            Securities, the amounts of interest and/or principal due them on each
                                            Distribution Date out of the funds available for distribution on such
                                            date in the related Security Account and, to the extent described in
                                            the related Prospectus Supplement, by the right of such holders to
                                            receive future distributions on the assets in the related Trust Fund
                                            that would otherwise have been payable to the holders of Subordinated
                                            Securities; (ii) reducing the ownership interest (if applicable) of
                                            the related Subordinated Securities; or (iii) a combination of
                                            clauses (i) and (ii) above. If so specified in the related Prospectus
                                            Supplement, subordination may apply only in the event of certain
                                            types of losses not covered by other forms of credit support, such as
                                            hazard losses not covered by standard hazard insurance policies or
                                            losses due to the bankruptcy or fraud of the borrower. The related
                                            Prospectus Supplement will set forth information concerning, among
                                            other things, the amount of subordination of a class or classes of
                                            Subordinated Securities in a Series, the circumstances in which such
                                            subordination will be applicable, and the manner, if any, in which
                                            the amount of subordination will decrease over time.

B. Reserve Account........................  One or more reserve accounts or other cash accounts (each, a 'Reserve
                                            Account') may be established and maintained for each Series of
                                            Securities. The related Prospectus Supplement will specify whether or
                                            not such Reserve Accounts will be included in the corpus of the Trust
                                            Fund for such Series and will also specify the manner of funding such
                                            Reserve Accounts and the conditions under which the amounts in any
                                            such Reserve Accounts will be used to make distributions to holders
                                            of Securities of a particular class or released from such Reserve
                                            Accounts.

C. Letter of Credit.......................  If so specified in the related Prospectus Supplement, credit support
                                            may be provided by one or more letters of credit. A letter of credit
                                            may provide limited protection against certain losses in addition to

                                            with the origination or sale of a Loan. The issuer of the letter of
                                            credit (the 'L/C Bank') will be obligated to honor demands with
                                            respect to such letter of credit, to the extent of the amount
                                            available thereunder, and to provide funds under the circumstances
                                            and subject to such conditions as are specified in the related
                                            Prospectus Supplement. The liability of the L/C Bank under its letter
                                            of credit will be reduced by the amount of unreimbursed payments
                                            thereunder.

                                            be an amount equal to a percentage specified in the related
                                            Prospectus Supplement of the initial aggregate outstanding principal
                                            balance of the Loans in the related Trust Fund or one or more classes
                                            of Securities of the related Series (the 'L/C Percentage'). The
                                            maximum amount available at any time to be paid under a letter of
                                            credit will be determined in the manner specified therein and in the
                                            related Prospectus Supplement.

                                            distributions of interest and/or full distributions of principal on
                                            the basis of a schedule of principal distributions set forth in or
                                            determined in the manner specified in the related Prospectus
                                            Supplement. If specified in the related Prospectus Supplement, one or

                                            Securities, a portion of the interest payment on each Loan may be
                                            applied as an additional distribution in respect of principal to
                                            reduce the principal balance of a certain class or classes of
                                            Securities and, thus, accelerate the rate of payment of principal on

                                            required Advance, the Trustee may be obligated to advance such

                                            or the holder of the ownership interest in a FASIT, may have the
                                            option to effect early retirement of a Series of Securities through
                                            the purchase of the Trust Fund Assets. The Master Servicer will
                                            deposit the proceeds of any such purchase in the Security Account for

                                            specified in the related Prospectus Supplement. The exercise of such
                                            right will effect early retirement of the Securities of that Series,
                                            but the right of the Master Servicer, such other person or, if

                                            the REMIC residual interest or FASIT ownership interest, to so
                                            purchase is subject to the principal balance of the related Trust
                                            Fund Assets being less than the percentage specified in the related
                                            Prospectus Supplement of the aggregate principal balance of the Trust
                                            Fund Assets at the Cut-off Date for the Series. The foregoing is
                                            subject to the provision that if a REMIC election is made with
                                            respect to a Trust Fund, any repurchase will be made only in
                                            connection with a 'qualified liquidation' of the REMIC within the
                                            meaning of Section 860F(g)(4) of the Code, and if a FASIT election is
                                            made with respect to a Trust Fund, any repurchase will be made only
                                            if such repurchase would not be a prohibited transaction within the
                                            meaning of section 860L(e)(2) of the Code.

Legal Investment..........................  The Prospectus Supplement for each series of Securities will specify
                                            which, if any, of the classes of Securities offered thereby
                                            constitute 'mortgage related securities' for purposes of the
                                            Secondary Mortgage Market Enhancement Act of 1984 ('SMMEA'). Classes
                                            of Securities that qualify as 'mortgage related securities' will be
                                            legal investments for 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. Institutions whose investment activities are subject to
                                            review by federal or state authorities should consult with their
                                            counsel or the applicable authorities to determine whether an
                                            investment in a particular class of Securities (whether or not such
                                            class constitutes a 'mortgage related security') complies with
                                            applicable guidelines, policy statements or restrictions. See 'Legal
                                            Investment'.

Federal Income Tax Consequences...........  The federal income tax consequences to Securityholders will vary
                                            depending on whether one or more elections are made to treat the
                                            Trust Fund or specified portions thereof as either a REMIC or a FASIT
                                            under the provisions of the Internal Revenue Code of 1986, as amended
                                            (the 'Code'). The Prospectus Supplement for each Series of Securities
                                            will specify whether such an election will be made.

                                            If a REMIC election or a FASIT election is made, Securities
                                            representing regular interests in a REMIC or FASIT will generally be
                                            treated as evidences of indebtedness for federal income tax purposes.
                                            Stated interest on such regular interests will be taxable as ordinary
                                            income and taken into account using the accrual method of accounting,
                                            regardless of the holder's normal accounting method. If neither a

                                            Certain classes of Securities may be issued with OID. A holder should
                                            be aware that the Code and the Treasury regulations promulgated
                                            thereunder do not adequately address certain issues relevant to
                                            prepayable securities, such as the Securities.

                                            will do so without giving effect to delays and reductions in
                                            distributions attributable to a default or delinquency on the Loans,
                                            except possibly to the extent that it can be established that such
                                            amounts are uncollectible. As a result, the amount of income
                                            (including OID) reported by a holder of a Security in any period
                                            could significantly exceed the amount of cash distributed to such
                                            holder in that period.

                                            In the opinion of Brown & Wood LLP, if a REMIC election is made with
                                            respect to a Series of Securities, then the arrangement by which such
                                            Securities are issued will be treated as a REMIC as long as all of
                                            the provisions of the applicable Agreement are complied with.
                                            Securities will be designated as 'regular interests' or 'residual
                                            interests' in a REMIC. A REMIC generally will not be subject to
                                            entity-level tax. Rather, the taxable income or net loss of a REMIC
                                            will be taken into account by the holders of residual interests. Such
                                            holders will report their proportionate share of the taxable income
                                            of the REMIC whether or not they receive cash distributions from the
                                            REMIC attributable to such income. The portion of the REMIC taxable
                                            income consisting of 'excess inclusions' generally may not be offset
                                            by otherwise allowable deductions of the holder, including net
                                            operating loss deductions.

                                            In the opinion of Brown & Wood LLP, if a FASIT election is made with
                                            respect to a Series of Securities, then the arrangement by which such
                                            Securities are issued will be treated as a FASIT as long as all of
                                            the provisions of the applicable Agreement are complied with.
                                            Securities will be designated as regular interests or as the
                                            ownership interest. The FASIT generally will not be subject to an
                                            entity-level tax. Rather, the taxable income or net loss of the FASIT
                                            will be taken into account by the holder of the ownership interest
                                            whether or not the holder receives cash distributions from the FASIT
                                            attributable to such income. The ownership interest generally must be
                                            held at all times by a domestic C corporation (an 'Eligible
                                            Corporation'). Furthermore, certain regular interests referred to as
                                            High-Yield interests are only suitable investments for Eligible
                                            Corporations. Income derived from holding ownership interests and
                                            income derived from holding High-Yield interests generally may not be
                                            offset by otherwise allowable deductions, including net operating
                                            loss deductions.

                                            In the opinion of Brown & Wood LLP, if a REMIC or a FASIT election is
                                            not made with respect to a Series of Securities, then the arrangement
                                            by which such Securities are issued either will be classified as a
                                            grantor trust under Subpart E, Part I of Subchapter J of the Code or
                                            as a partnership. The Trust Fund will not be a publicly traded
                                            partnership taxable as a corporation as long as all of the provisions
                                            of the related Agreement are complied with. If Notes are issued by
                                            such Trust Fund, such Notes will be treated as indebtedness for
                                            federal income tax purposes. The holders of the Certificates issued
                                            by such Trust Fund will agree to treat the Certificates either as
                                            equity interests in a partnership or in a grantor trust.

ERISA Considerations......................  A fiduciary of any employee benefit plan or other retirement plan or
                                            arrangement subject to the Employee Retirement Income Security Act of
                                            1974, as amended ('ERISA'), or the Code should carefully review with
                                            its legal advisors whether the purchase or holding of Securities
                                            could give rise to a transaction prohibited or not otherwise
                                            permissible under ERISA or the Code. See 'ERISA Considerations'.
                                            Certain classes of Securities may not be transferred unless the
                                            Trustee and the Depositor are furnished with a letter of
                                            representation or an opinion of counsel to the effect that such
                                            transfer will not result in a violation of the prohibited transaction
                                            provisions of ERISA and the Code and will not subject the Trustee,

                                  RISK FACTORS
 
     Investors should consider the following factors in connection with the
purchase of the Securities.
 
LIMITED LIQUIDITY
 
     No market for the Securities of any Series will exist prior to the issuance
thereof, and no assurance can be given that a secondary market will develop or,
if it does develop, that it will provide Securityholders with liquidity of
investment or will continue for the life of the Securities of such Series.
 
LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO SELLERS, DEPOSITOR OR MASTER
SERVICER
 
     The Depositor does not have, nor is it expected to have, any significant
assets. Unless otherwise specified in the related Prospectus Supplement, the
Securities of a Series will be payable solely from the Trust Fund for such
Securities and will not have any claim against or security interest in the Trust
Fund for any other Series. There will be no recourse to the Depositor or any
other person for any failure to receive distributions on the Securities.
Further, at the times set forth in the related Prospectus Supplement, certain
Trust Fund Assets and/or any balance remaining in the Security Account
immediately after making all payments due on the Securities of such Series,
after making adequate provision for future payments on certain classes of
Securities and after making any other payments specified in the related
Prospectus Supplement, may be promptly released or remitted to the Depositor,
the Master Servicer, any credit enhancement provider or any other person
entitled thereto and will no longer be available for making payments to
Securityholders. Consequently, holders of Securities of each Series must rely
solely upon payments with respect to the Trust Fund Assets and the other assets
constituting the Trust Fund for a Series of Securities, including, if
applicable, any amounts available pursuant to any credit enhancement for such
Series, for the payment of principal of and interest on the Securities of such
Series.
 
     The Securities will not represent an interest in or obligation of the
Depositor, the Master Servicer, any Seller or any of their respective
affiliates. The only obligations, if any, of the Depositor with respect to the
Trust Fund Assets or the Securities of any Series will be pursuant to certain
representations and warranties. 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 Loans with respect to which there has been a breach of any
representation or warranty which materially and adversely affects the interests
of the Securityholders in such Loans. If, for example, the Depositor were
required to repurchase a Loan, its only sources of funds to make such repurchase
would be from funds obtained (i) from the enforcement of a corresponding
obligation, if any, on the part of the related Seller or originator of such Loan
or (ii) to the extent provided in the related Prospectus Supplement, from a
Reserve Account or similar credit enhancement established to provide funds for
such repurchases.
 
     The only obligations of any Seller with respect to Trust Fund Assets or the
Securities of any Series will be pursuant to certain representations and
warranties and certain document delivery requirements. A Seller may be required
to repurchase or substitute for any Loan with respect to which such
representations and warranties or certain document delivery requirements are
breached (and in the case of any such breach of representations and warranties,
such breach materially and adversely affects the interest of the Securityholders
in such Loan). There is no assurance, however, that such Seller will have the
financial ability to effect such repurchase or substitution. Although the Master
Servicer may be obligated to enforce such obligation to the extent described
under 'Loan Program -- Representations by Sellers; Repurchases,' the Master
Servicer will not be obligated to purchase or replace such Loan if the Seller
defaults on its obligation (nor will the Master Servicer otherwise be obligated
to purchase or replace any such Loan for any other reason).
 
CREDIT ENHANCEMENT -- LIMITATIONS
 
     Although credit enhancement is intended to reduce the risk of delinquent
payments or losses to holders of Securities entitled to the benefit thereof, the
amount of such credit enhancement will be limited, as set forth in the related
Prospectus Supplement, and may be subject to periodic reduction in accordance
with a schedule or formula or otherwise decline, and could be depleted under
certain circumstances prior to the payment in full of the related Series of
Securities, and as a result Securityholders of the related Series may suffer
losses. Moreover, such credit enhancement may not cover all potential losses or
risks. For example, credit enhancement may or may not cover fraud or negligence
by a loan originator or other parties. In addition, the Trustee will generally
be permitted to reduce, terminate or substitute all or a portion of the credit
enhancement for any Series of
 
                                       14
 <PAGE>
<PAGE>
Securities, provided the applicable Rating Agency indicates that the
then-current rating of the Securities of such Series will not be adversely
affected. See 'Credit Enhancement'.
 
PREPAYMENT AND YIELD CONSIDERATIONS
 
     The timing of principal payments of the Securities of a Series will be
affected by a number of factors, including the following: (i) the extent of
prepayments (including for this purpose prepayments resulting from refinancing
or liquidations of the Loans due to defaults, casualties, condemnations and
repurchases by the Depositor or a Seller) of the Loans comprising the Trust
Fund, which prepayments may be influenced by a variety of factors including
general economic conditions, prevailing interest rate levels, the availability
of alternative financing and homeowner mobility, (ii) the manner of allocating
principal and/or payments among the classes of Securities of a Series as
specified in the related Prospectus Supplement, (iii) the exercise by the party
entitled thereto of any right of optional termination and (iv) the rate and
timing of payment defaults and losses incurred with respect to the Trust Fund
Assets. The repurchase of Loans by the Depositor or a Seller may result from
repurchases of Trust Fund Assets due to material breaches of the Depositor's or
such Seller's representations and warranties, as applicable. The yields to
maturity and weighted average lives of the Securities will be affected primarily
by the rate and timing of prepayment of the Loans comprising the Trust Fund
Assets. In addition, the yields to maturity and weighted average lives of the
Securities will be affected by the distribution of amounts remaining in any
Pre-Funding Account following the end of the related Funding Period. Any
reinvestment risks resulting from a faster or slower incidence of prepayment of
Loans held by a Trust Fund will be borne entirely by the holders of one or more
classes of the related Series of Securities. See 'Yield and Prepayment
Considerations' and 'The Agreements -- Pre-Funding Account'.
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Securities were to accrue through the day immediately preceding
each Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate. See 'Description of the
Securities -- Distributions on Securities -- Distributions of Interest'.
 
LOANS WITH BALLOON PAYMENTS HAVE GREATER RISK OF BORROWER DEFAULT
 
     Certain of the Loans as of the related Cut-off Date may not be fully
amortizing over their terms to maturity and, thus, will require substantial
principal payments (i.e., balloon payments) at their stated maturity. Loans with
balloon payments involve a greater degree of risk because the ability of a
borrower to make a balloon payment typically will depend upon its ability either
to timely refinance the loan or to timely sell the related Property. The ability
of a borrower to accomplish either of these goals will be affected by a number
of factors, including the level of available mortgage rates at the time of sale
or refinancing, the borrower's equity in the related Property, the financial
condition of the borrower and tax laws. Losses on such Loans that are not
otherwise covered by the credit enhancement described in the applicable
Prospectus Supplement will be borne by the holders of one or more classes of
Securities of the related Series.
 
NATURE OF MORTGAGES
 
     Property Values May Decline. The value of the Properties underlying the
Loans may decline over time. Among the factors that could adversely affect the
value of the Properties are an overall decline in the residential real estate
market in the areas in which the Properties are located or a decline in the
general condition of the Properties as a result of failure of borrowers to
maintain adequately the Properties or of natural disasters that are not
necessarily covered by insurance, such as earthquakes and floods. Such decline
could extinguish the value of the interest of a junior mortgagee in the Property
before having any effect on the interest of the related senior mortgagee. If
such a decline occurs, the actual rates of delinquencies, foreclosures and
losses on all Loans could be higher than those currently experienced in the
mortgage lending industry in general. Losses on such Loans that are not
otherwise covered by the credit enhancement described in the applicable
Prospectus Supplement will be borne by the holder of one or more classes of
Securities of the related Series.
 
                                       15

<PAGE>
     Delays Due to Liquidation of Properties. Even assuming that the Properties
provide adequate security for the Loans, substantial delays could be encountered
in connection with the liquidation of defaulted Loans and corresponding delays
in the receipt of related proceeds by Securityholders could occur. An action to
foreclose on a Property securing a Loan is regulated by state statutes and rules
and is subject to many of the delays and expenses of other lawsuits if defenses
or counterclaims are interposed, sometimes requiring several years to complete.
Furthermore, in some states an action to obtain a deficiency judgment is not
permitted following a nonjudicial sale of a Property. In the event of a default
by a borrower, these restrictions, among other things, may impede the ability of
the Master Servicer to foreclose on or sell the Property or to obtain
liquidation proceeds sufficient to repay all amounts due on the related Loan. In
addition, the Master Servicer will be entitled to deduct from related
liquidation proceeds all expenses reasonably incurred in attempting to recover
amounts due on defaulted Loans and not yet repaid, including payments to senior
lienholders, legal fees and costs of legal action, real estate taxes and
maintenance and preservation expenses.
 
     Disproportionate Effect of Liquidation Expenses. Liquidation expenses with
respect to defaulted loans generally do not vary directly with the outstanding
principal balance of the loan at the time of default. Therefore, assuming that a
servicer took the same steps in realizing upon a defaulted loan having a small
remaining principal balance as it would in the case of a defaulted 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 loan than would be the case with the defaulted loan having
a large remaining principal balance.
 
     Home Equity Loans; Junior Liens May Be More Difficult to Foreclose. Since
the mortgages and deeds of trust securing the Home Equity Loans and the Home
Improvement Contracts will be primarily junior liens subordinate to the rights
of the mortgagee under the related senior mortgage(s) or deed(s) of trust, the
proceeds from any liquidation, insurance or condemnation proceeds will be
available to satisfy the outstanding balance of such junior lien only to the
extent that the claims of such senior mortgagees have been satisfied in full,
including any related foreclosure costs. In addition, if a junior mortgagee
forecloses on the property securing a junior mortgage, it forecloses subject to
any senior mortgage and must either pay the entire amount due on any senior
mortgage to the related senior mortgagee at or prior to the foreclosure sale or
undertake the obligation to make payments on any such senior mortgage in the
event the mortgagor is in default thereunder in order to protect the junior
mortgagee's interest in the property. The Trust Fund will not have any source of
funds to satisfy any senior mortgages or make payments due to any senior
mortgagees and may therefore effectively be prevented from foreclosing on the
related property.
 
     Certain states have imposed statutory and judicial restrictions that limit
the remedies of a secured lender in the event that the proceeds of any sale
under a deed of trust or other foreclosure proceedings are insufficient to pay
amounts owed to such secured lender. In certain states, including California, if
a lender simultaneously originates a loan secured by a senior lien on a
particular property and a loan secured by a junior lien on the same property,
such a lender as the holder of the junior lien may be precluded from obtaining a
deficiency judgment with respect to the excess of the aggregate amount owed
under both such loans over the proceeds of any sale under a deed of trust or
other foreclosure proceedings. See 'Certain Legal Aspects of the Loans -- Anti-
Deficiency Legislation; Bankruptcy Laws; Tax Liens'.
 
     Consumer Protection Laws. Applicable state laws generally regulate interest
rates and other charges, require certain disclosures, and require licensing of
certain originators and servicers of Loans. In addition, most states have other
laws, public policy and general principles of equity relating to the protection
of consumers, unfair and deceptive acts and practices which may apply to the
origination, servicing and collection of the Loans. Depending on the provisions
of the applicable law and the specific facts and circumstances involved,
violations of these laws, policies and principles may limit the ability of the
Master Servicer to collect all or part of the principal of or interest on the
Loans, may entitle the borrower to a refund of amounts previously paid and, in
addition, could subject the Master Servicer to damages and administrative
sanctions. See 'Certain Legal Aspects of the Loans'.
 
MULTIFAMILY LOANS SUBJECT TO MORE RISKS THAN SINGLE FAMILY LOANS
 
     Multifamily lending may be viewed as exposing the lender to a greater risk
of loss than single family residential lending. Owners of multifamily
residential properties rely on monthly lease payments from tenants to pay for
maintenance and other operating expenses of such properties, to fund capital
improvements and to
 
                                       16
 <PAGE>
<PAGE>
service any mortgage loan and any other debt that may be secured by such
properties. Various factors, many of which are beyond the control of the owner
or operator of such a property, may affect the economic viability of that
property.
 
     Changes in payment patterns by tenants may result from a variety of social,
legal and economic factors. Economic factors including the rate of inflation,
unemployment levels and relative rates offered for various types of housing may
be reflected in changes in payment patterns including increased risks of
defaults by tenants and higher vacancy rates. Adverse economic conditions,
either local or national, may limit the amount of rent that can be charged and
may result in a reduction in timely lease payments or a reduction in occupancy
levels. Occupancy and rent levels may also be affected by construction of
additional housing units, competition and local politics, including rent
stabilization or rent control laws and policies. In addition, the level of
mortgage interest rates may encourage tenants to purchase single family housing.
The Depositor is unable to determine and has no basis to predict whether, or to
what extent, economic, legal or social factors will affect future rental or
payment patterns.
 
     The location and construction quality of a particular building may affect
the occupancy level as well as the rents that may be charged for individual
units. The characteristics of a neighborhood may change over time or in relation
to newer developments. The effects of poor construction quality will increase
over time in the form of increased maintenance and capital improvements. Even
good construction will deteriorate over time if adequate maintenance is not
performed in a timely fashion.
 
HOME IMPROVEMENT CONTRACTS AND HOME EQUITY LOANS MAY BE UNDERCOLLATERALIZED AND
SUBJECT TO GREATER RISK OF COLLECTION
 
     If specified in the related Prospectus Supplement, the Trust Fund for any
Series may include Home Equity Loans and Home Improvement Contracts that were
originated with Loan-to-Value Ratios or Combined Loan-to-Value Ratios in excess
of the value of the related Mortgaged Property pledged as security therefor.
Under such circumstances, the Trust Fund for the related Series could be treated
as a general unsecured creditor as to any undercollateralized portion of any
such Loan. In the event of a default under a Loan that is undercollateralized,
the related Trust Fund will have recourse only against the borrower's assets
generally for the undercollateralized portion of the Loan, along with all other
general unsecured creditors of the borrower. In a bankruptcy or insolvency
proceeding relating to a borrower on any such Loan, the undercollateralized
obligations of the borrower with respect to such Loan will be treated as an
unsecured loan and may be discharged by the bankruptcy court even though such
obligations are not fully satisfied. Losses on any such undercollateralized
Loans that are not otherwise covered by the credit enhancement described in the
applicable Prospectus Supplement will be borne by the holder of one or more
classes of Securities of the related Series.
 
HOME IMPROVEMENT CONTRACTS MAY BE UNSECURED AND SUBJECT TO GREATER RISK OF
COLLECTION
 
     If so specified in the related Prospectus Supplement, the Trust Fund for
any Series may include Home Improvement Contracts that are not secured by an
interest in real estate or otherwise. In the event of a default under a Loan
that is unsecured, the related Trust Fund will only have recourse against the
borrower's assets generally along with all other general unsecured creditors of
the borrower. In a bankruptcy or insolvency proceeding relating to a borrower on
any such Loan, the obligations of the borrower in respect to such Loan may be
discharged by the bankruptcy court even though such obligations are not fully
satisfied. Losses on any such unsecured Loans that are not otherwise covered by
the credit enhancement described in the applicable Prospectus Supplement will be
borne by the holder of one or more classes of Securities of the related Series.
 
CERTAIN ENVIRONMENTAL LIABILITIES MAY REDUCE AMOUNTS AVAILABLE TO
SECURITYHOLDERS
 
     Real property pledged as security to a lender may be subject to certain
environmental risks. Under the laws of certain states, contamination of a
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 the lien of an existing
mortgage against 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 that require remedy at a property, if agents or employees of the
lender have become sufficiently involved in the operations of the borrower,
 
                                       17
 <PAGE>
<PAGE>
regardless of whether the environmental damage or threat was caused by a prior
owner. Such costs could result in a loss to the holders of one or more classes
of Securities of the related Series. A lender also risks such liability on
foreclosure of the related property. See 'Certain Legal Aspects of the
Loans -- Environmental Risks'.
 
CERTAIN OTHER LEGAL ASPECTS OF THE LOANS THAT MAY DELAY OR REDUCE AMOUNTS
AVAILABLE TO SECURITYHOLDERS
 
     Consumer Protection Laws. The Loans may also be subject to federal laws,
including:
 
          (i) the Federal Truth in Lending Act and Regulation Z promulgated
     thereunder, which require certain disclosures to the borrowers regarding
     the terms of the Loans;
 
          (ii) the Equal Credit Opportunity Act and Regulation B promulgated
     thereunder, which prohibit discrimination on the basis of age, race, color,
     sex, religion, marital status, national origin, receipt of public
     assistance or the exercise of any right under the Consumer Credit
     Protection Act, in the extension of credit;
 
          (iii) the Fair Credit Reporting Act, which regulates the use and
     reporting of information related to the borrower's credit experience; and
 
          (iv) for Loans that were originated or closed after November 7, 1989,
     the Home Equity Loan Consumer Protection Act of 1988, which requires
     additional application disclosures, limits changes that may be made to the
     loan documents without the borrower's consent and restricts a lender's
     ability to declare a default or to suspend or reduce a borrower's credit
     limit to certain enumerated events.
 
     The Riegle Act. Certain mortgage loans may be subject to the Riegle
Community Development and Regulatory Improvement Act of 1994 (the 'Riegle Act')
which incorporates the Home Ownership and Equity Protection Act of 1994. These
provisions impose additional disclosure and other requirements on creditors with
respect to non-purchase money mortgage loans with high interest rates or high
up-front fees and charges. The provisions of the Riegle Act apply on a mandatory
basis to all mortgage loans originated on or after October 1, 1995. These
provisions can impose specific statutory liabilities upon creditors who fail to
comply with their provisions and may affect the enforceability of the related
loans. In addition, any assignee of the creditor would generally be subject to
all claims and defenses that the consumer could assert against the creditor,
including, without limitation, the right to rescind the mortgage loan.
 
     Holder in Due Course Rules. The Home Improvement Contracts are also subject
to the Preservation of Consumers' Claims and Defenses regulations of the Federal
Trade Commission and other similar federal and state statutes and regulations
(collectively, the 'Holder in Due Course Rules'), which are intended to defeat
the ability of the transferor of a consumer credit contract which 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 debtor
thereunder. The effect of the Holder in Due Course Rules is to subject the
assignee of such a Home Improvement Contract (such as the Trust Fund) to all
claims and defenses which the obligor under the Home Improvement Contract could
assert against the seller of the related goods. Liability under this rule is
limited to amounts paid under the Home Improvement Contract; however, the
obligor under the Home Improvement Contract also may be able to assert the rule
to set off remaining amounts due as a defense against a claim brought by the
Trust Fund against such obligor. See 'Certain Legal Aspects of the Loans'.
 
     Violations of certain provisions of these federal laws may limit the
ability of the Master Servicer to collect all or part of the principal of or
interest on the Loans and in addition could subject the Trust Fund to damages
and administrative enforcement. Losses on such Loans that are not otherwise
covered by the credit enhancement described in the applicable Prospectus
Supplement will be borne by the holders of one or more classes of Securities of
the related Series. See 'Certain Legal Aspects of the Loans'.
 
RATING OF THE SECURITIES -- LIMITATIONS
 
     It will be a condition to the issuance of a class of Securities offered
hereby that they be rated in one of the four highest rating categories by the
Rating Agency identified in the related Prospectus Supplement. Any such rating
would be based on, among other things, the adequacy of the value of the related
Trust Fund Assets and any credit enhancement with respect to such class and will
represent such Rating Agency's assessment solely of the likelihood that holders
of such class of Securities will receive payments to which such Securityholders
are
 
                                       18
 <PAGE>
<PAGE>
entitled under the related Agreement. Such rating will not constitute an
assessment of the likelihood that principal prepayments on the related Loans
will be made, the degree to which the rate of such prepayments might differ from
that originally anticipated or the likelihood of early optional termination of
the Series of Securities. Such rating shall not be deemed a recommendation to
purchase, hold or sell Securities, inasmuch as it does not address market price
or suitability for a particular investor. Such rating will not address the
possibility that prepayment at higher or lower rates than anticipated by an
investor may cause such investor to experience a lower than anticipated yield or
that an investor purchasing a Security at a significant premium might fail to
recoup its initial investment under certain prepayment scenarios. In addition,
if such rating relates to a Series with a Pre-Funding Account, such rating will
not address the ability of the related Trust Fund to acquire Subsequent Loans,
any potential prepayment of the Securities resulting from distribution to
Securityholders of amounts remaining in the Pre-Funding Account following the
end of the Funding Period, or the effect on the yield to Securityholders
resulting therefrom.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series of Securities, such rating might also be lowered or
withdrawn because of, among other reasons, an adverse change in the financial or
other condition of a credit enhancement provider or a change in the rating of
such credit enhancement provider's long term debt.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a class of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of similar loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of similar loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that the values of any Properties have
remained or will remain at their levels on the respective dates of origination
of the related Loans. If the residential real estate markets should experience
an overall decline in property values such that the outstanding principal
balances of the Loans in a particular Trust Fund and any secondary financing on
the related Properties become equal to or greater than the value of the
Properties, the rates of delinquencies, foreclosures and losses could be higher
than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions (which may or may not affect real property
values) may affect the timely payment by mortgagors of scheduled payments of
principal and interest on the Loans and, accordingly, the rates of
delinquencies, foreclosures and losses with respect to any Trust Fund. To the
extent that such losses are not covered by credit enhancement, such losses will
be borne, at least in part, by the holders of one or more classes of Securities
of the related Series. See 'Rating'.
 
BOOK-ENTRY REGISTRATION MAY REDUCE LIQUIDITY OF THE SECURITIES
 
     If issued in book-entry form, such registration may reduce the liquidity of
the Securities in the secondary trading market since investors may be unwilling
to purchase Securities for which they cannot obtain physical certificates. Since
transactions in book-entry Securities can be effected only through the
Depository Trust Company ('DTC'), participating organizations, Financial
Intermediaries and certain banks, the ability of a Securityholder to pledge a
book-entry Security to persons or entities that do not participate in the DTC
system may be limited due to lack of a physical certificate representing such
Securities. Securities Owners will not be recognized as Securityholders as such
term is used in the related Agreement, and Security Owners will be permitted to
exercise the rights of Securityholders only indirectly through DTC and its
Participants.
 
     In addition, Securityholders may experience some delay in their receipt of
distributions of interest and principal on book-entry Securities since
distributions are required to be forwarded by the Trustee to DTC and DTC will
then be required to credit such distributions to the accounts of Depository
participants which thereafter will be required to credit them to the accounts of
Securityholders either directly or indirectly through Financial Intermediaries.
See 'Description of the Securities -- Book-Entry Registration of Securities'.
 
                                       19

PRE-FUNDING ACCOUNTS
 
     Pre-Funded Amounts Not Used to Cover Losses. If so provided in the related
Prospectus Supplement, on the closing date specified in such Prospectus
Supplement (the 'Closing Date') the Depositor will deposit cash in an amount
(the 'Pre-Funded Amount') specified in such Prospectus Supplement into an
account (the 'Pre-Funding Account'). In no event shall the Pre-Funded Amount
exceed 50% of the initial aggregate principal amount of the Certificates and/or
Notes of the related Series of Securities. The Pre-Funded Amount will be used to
purchase Loans ('Subsequent Loans') in a period from the related Closing Date to
a date not more than one year after such Closing Date (such period, the 'Funding
Period') from the Depositor (which, in turn, will acquire such Subsequent Loans
from the Seller or Sellers specified in the related Prospectus Supplement). The
Pre-Funding Account will be maintained with the Trustee for the related Series
of Securities and is designed solely to hold funds to be applied by such Trustee
during the Funding Period to pay to the Depositor the purchase price for
Subsequent Loans. Monies on deposit in the Pre-Funding Account will not be
available to cover losses on or in respect of the related Loans.
 
     Unused Pre-Funded Amounts at the end of Funding Period Will Be Distributed
As Principal Prepayment to Securityholders. To the extent that the entire
Pre-Funded Amount has not been applied to the purchase of Subsequent Loans by
the end of the related Funding Period, any amounts remaining in the Pre-Funding
Account will be distributed as a prepayment of principal to Securityholders on
the Distribution Date immediately following the end of the Funding Period, in
the amounts and pursuant to the priorities set forth in the related Prospectus
Supplement. Any reinvestment risk resulting from such prepayment will be borne
entirely by the holders of one or more classes of the related Series of
Securities.
 
BANKRUPTCY OR INSOLVENCY OF THE SELLER, THE DEPOSITOR OR THE MASTER SERVICER
COULD LEAD TO DELAY OR REDUCTION OF AMOUNTS PAYABLE TO SECURITYHOLDERS
 
     The Seller and the Depositor will treat the transfer of the Loans by the
Seller to the Depositor as a sale for accounting purposes. The Depositor and the
Trust Fund will treat the transfer of Loans from the Depositor to the Trust Fund
as a sale for accounting purposes. As a sale of the Loans by the Seller to the
Depositor, the Loans would not be part of the Seller's bankruptcy estate and
would not be available to the Seller's creditors. However, in the event of the
insolvency of the Seller, it is possible that the bankruptcy trustee or a
creditor of the Seller may attempt to recharacterize the sale of the Loans as a
borrowing by the Seller, secured by a pledge of the Loans. Similarly, as a sale
of the Loans by the Depositor to the Trust Fund, the Loans would not be part of
the Depositor's bankruptcy estate and would not be available to the Depositor's
creditors. However, in the event of the insolvency of the Depositor, it is
possible that the bankruptcy trustee or a creditor of the Depositor may attempt
to recharacterize the sale of the Loans as a borrowing by the Depositor, secured
by a pledge of the Loans. In either case, this position, if argued before or
accepted by a court, could prevent timely payments of amounts due on the
Securities and result in a reduction of payments due on the Securities.
 
     In the event of a bankruptcy or insolvency of the Master Servicer, the
bankruptcy trustee or receiver may have the power to prevent the Trustee or the
Securityholders from appointing a successor Servicer. The time period, if any,
during which cash collections may be commingled with the Master Servicer's own
funds prior to each Distribution Date will be specified in the related
Prospectus Supplement. In the event of the insolvency of the Master Servicer and
if such cash collections are commingled with the Master Servicer's own funds for
at least ten days, the Trust Fund will likely not have a perfected interest in
such collections since such collections would not have been deposited in a
segregated account within ten days after the collection thereof, and the
inclusion thereof in the bankruptcy estate of the Master Servicer may result in
delays in payment and failure to pay amounts due on the Securities of the
related Series.
 
     In addition, federal and state statutory provisions, including the federal
bankruptcy laws and state laws affording relief to debtors, may interfere with
or affect the ability of the secured mortgage lender to realize upon its
security. For example, in a proceeding under Title 11 of the United States Code
Section 101 et seq. and the rules and regulations promulgated thereunder, as
amended (the 'Bankruptcy Code'), a lender may not foreclose on a mortgaged
property without the permission of the bankruptcy court. The rehabilitation plan
proposed by the debtor may provide, if the mortgaged property is not the
debtor's principal residence and the court determines that the value of the
mortgaged property is less than the principal balance of the mortgage loan, for
the reduction of the secured indebtedness to the value of the mortgaged property
as of the date of the commencement of the bankruptcy, rendering the lender a
general unsecured creditor for the difference, and also may reduce the
 
                                       20
 <PAGE>
<PAGE>
monthly payments due under such mortgage loan, change the rate of interest and
alter the mortgage loan repayment schedule. The effect of any such proceedings
under the Bankruptcy Code, including but not limited to any automatic stay,
could result in delays in receiving payments on the Loans underlying a Series of
Securities and possible reductions in the aggregate amount of such payments.
 
HOLDERS OF ORIGINAL ISSUE DISCOUNT SECURITIES REQUIRED TO INCLUDE ORIGINAL ISSUE
DISCOUNT IN ORDINARY GROSS INCOME FOR FEDERAL INCOME TAX PURPOSES AS IT ACCRUES
 
     Debt Securities that are Compound Interest Securities will be, and certain
of the other Debt Securities may be, issued with original discount for federal
income tax purposes. A holder of Debt Securities issued with original issue
discount will be required to include original issue discount in ordinary gross
income for federal income tax purposes as it accrues, in advance of receipt of
the cash attributable to such income. Accrued but unpaid interest on the Debt
Securities that are Compound Interest Securities generally will be treated as
original issue discount for this purpose. See 'Federal Income Tax
Consequences -- Taxation of Debt Securities -- Interest and Acquisition
Discount' and ' -- Market Discount' herein.
 
VALUE OF TRUST FUND ASSETS COULD BE INSUFFICIENT TO PAY PRINCIPAL AND INTEREST
ON THE SECURITIES
 
     There is no assurance that the market value of the Trust Fund Assets or any
other assets relating to a Series of Securities described under 'Credit
Enhancement' herein will at any time be equal to or greater than the principal
amount of the Securities of such Series then outstanding, plus accrued interest
thereon. Moreover, upon an event of default under the Agreement for a Series of
Securities and a sale of the related Trust Fund Assets or upon a sale of the
assets of a Trust Fund for a Series of Securities, the Trustee, the Master
Servicer, the credit enhancer, if any, and any other service provider specified
in the related Prospectus Supplement generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and other amounts owing
to such persons under the related Agreement prior to distributions to
Securityholders. Upon any such sale, the proceeds thereof may be insufficient to
pay in full the principal of and interest on the Securities of such Series.
 
DERIVATIVE TRANSACTIONS
 
     The Trust may enter into privately negotiated, over-the-counter hedging
transactions with various counterparties, including interest rate and
securities-based swaps, caps, collars and floors (collectively, 'Derivative
Transactions') to effectively fix the rate of interest that a Trust Fund pays on
one or more borrowings or series of borrowings. See 'Description of the
Securities -- Derivative Transactions'.
 
     Credit Risks. It is expected that if a Trust Fund enters into Derivative
Transactions it will do so with banks, financial institutions and recognized
dealers in Derivative Transactions. Entering into a Derivatives Transaction
directly with a counterparty subjects a Trust Fund to the credit risk that the
counterparty may default on an obligation to such Trust Fund. Such a risk
contrasts with transactions done through exchange markets, wherein credit risk
is reduced through the collection of variation margin and through the
interposition of a clearing organization as the guarantor of all transactions.
Clearing organizations transform the credit risk of individual counterparties
into the more remote risk of the failure of the clearing organization.
Additionally, the financial integrity of over-the-counter Derivative
Transactions is generally unsupported by other regulatory or self-regulatory
protections such as margin requirements, capital requirements, or financial
compliance programs. Therefore, there are much greater risks of defaults with
respect to over-the-counter privately negotiated Derivative Transactions than
with respect to exchange-traded transactions. If there is a default by the other
party to such a transaction, the related Trust Fund will have to rely on its
contractual remedies (which may be limited by bankruptcy, insolvency or similar
laws) pursuant to the agreements related to the Derivative Transactions.
 
     Legal Enforceability Risks. Privately negotiated over-the-counter
Derivative Transactions subject a Trust Fund to the risks of (a) a single
counterparty's legal incapacity to enter into or perform its obligations under a
given Derivative Transaction or class of Derivative Transactions, rendering such
Derivative Transactions unenforceable, (b) a court or regulatory body declaring
that classes of Derivative Transactions are unlawful or not in compliance with
applicable laws or regulations, rendering them invalid and unenforceable, or
(c) legislation which may be proposed or enacted which may affect the legal,
regulatory or tax status of Derivative Transactions to the detriment of the
related Trust Fund's interests.
 
                                       21
 <PAGE>
<PAGE>
     Basis Risks. Successful use of Derivative Transactions depends upon the
ability to predict movements of the overall securities or interest rate markets.
There might be an imperfect correlation, or even no correlation, between price
movements of a Derivative Transaction and price movements of the investments or
instruments being hedged. If a Trust Fund enters into Derivative Transactions at
the wrong time or market conditions are predicted incorrectly, the Derivative
Transaction may result in a substantial loss to such Trust Fund and hence the
related Securityholders.
 
                                 THE TRUST FUND
 
GENERAL
 
     The Securities of each Series will represent interests in the assets of the
related Trust Fund, and the Notes of each Series will be secured by the pledge
of the assets of the related Trust Fund. 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 certain assets (the 'Trust Fund Assets') consisting of a
pool (each, a 'Pool') comprised of Loans as specified in the related Prospectus
Supplement, together with payments in respect of such Loans, as specified in the
related Prospectus Supplement.* The Pool will be created on the first day of the
month of the issuance of the related Series of Securities or such other date
specified in the related Prospectus Supplement (the 'Cut-off Date'). The
Securities will be entitled to payment from the assets of the related Trust Fund
or Funds or other assets pledged for the benefit of the Securityholders, as
specified in the related Prospectus Supplement and will not be entitled to
payments in respect of the assets of any other trust fund established by the
Depositor.
 
     The Trust Fund Assets will be acquired by the Depositor, either directly or
through affiliates, from originators or sellers which may be affiliates of the
Depositor (the 'Sellers'), and conveyed without recourse by the Depositor to the
related Trust Fund. Loans acquired by the Depositor will have been originated in
accordance with the underwriting criteria specified below under 'Loan
Program -- Underwriting Standards' or as otherwise described in the related
Prospectus Supplement. See 'Loan Program -- Underwriting Standards'.
 
     The Depositor will cause the Trust Fund Assets to be assigned to the
Trustee named in the related Prospectus Supplement for the benefit of the
holders of the Securities of the related Series. The Master Servicer named in
the related Prospectus Supplement will service the Trust Fund Assets, either
directly or through other servicing institutions ('Sub-Servicers'), pursuant to
a Pooling and Servicing Agreement among the Depositor, the Master Servicer and
the Trustee with respect to a Series consisting of Certificates, or a master
servicing agreement (each, a 'Master Servicing Agreement') between the Trustee
and the Master Servicer with respect to a Series consisting of Certificates and
Notes, and will receive a fee for such services. See 'Loan Program' and 'The
Agreements'. With respect to Loans serviced by the Master Servicer through a
Sub-Servicer, the Master Servicer will remain liable for its servicing
obligations under the related Agreement as if the Master Servicer alone were
servicing such Loans.
 
     As used herein, 'Agreement' means, with respect to a Series consisting of
Certificates, the Pooling and Servicing Agreement, and with respect to a Series
consisting of Certificates and Notes, the Trust Agreement, the Indenture and the
Master Servicing Agreement, as the context requires.
 
     If so specified in the related Prospectus Supplement, a Trust Fund relating
to a Series of Securities may be a trust formed under the laws of the state
specified in the related Prospectus Supplement pursuant to a trust agreement
(each, a 'Trust Agreement') between the Depositor and the trustee of such Trust
Fund.
 
     With respect to each Trust Fund, prior to the initial offering of the
related Series of Securities, the Trust Fund will have no assets or liabilities.
No Trust Fund is expected to engage in any activities other than acquiring,
managing and holding of the related Trust Fund Assets and other assets
contemplated herein specified
 
- ------------------------------
 
* Whenever the terms 'Pool', 'Certificates', 'Notes' and 'Securities' are used
  in this Prospectus, such terms will be deemed to apply, unless the context
  indicates otherwise, to one specific Pool and the Securities of one Series
  including the Certificates representing certain undivided interests in, and/or
  Notes secured by the assets of, a single Trust Fund consisting primarily of
  the Loans in such Pool. Similarly, the term 'Pass-Through Rate' will refer to
  the pass-through rate borne by the Certificates and the term 'interest rate'
  will refer to the interest rate borne by the Notes of one specific Series, as
  applicable, and the term 'Trust Fund' will refer to one specific Trust Fund.

and in the related Prospectus Supplement and the proceeds thereof, issuing
Securities and making payments and distributions thereon and certain related
activities. No Trust Fund is expected to have any source of capital other than
its assets and any related credit enhancement.
 
     Unless otherwise specified in the related Prospectus Supplement, the only
obligations of the Depositor with respect to a Series of Securities will be to
obtain certain representations and warranties from the Sellers and, to the
extent such representations and warranties are not made by the Sellers directly
to the Trustee, to assign to the Trustee for such Series of Securities the
Depositor's rights with respect to such representations and warranties. See 'The
Agreements -- Assignment of the Trust Fund Assets'. The obligations of the
Master Servicer with respect to the Loans will consist principally of its
contractual servicing obligations under the related Agreement (including its
obligation to enforce the obligations of the Sub-Servicers or Sellers, or both,
as more fully described herein under 'Loan Program -- Representations by
Sellers; Repurchases' and 'The Agreements -- Sub-Servicing By Sellers' and
' -- Assignment of the Trust Fund Assets') and its obligation, if any, to make
certain cash advances in the event of delinquencies in payments of interest
and/or principal on or with respect to the Loans in the amounts described herein
under 'Description of the Securities -- Advances'. The obligations of the Master
Servicer to make advances may be subject to limitations, to the extent provided
herein and in the related Prospectus Supplement.
 
     The following is a brief description of the assets expected to be included
in the Trust Funds. If specific information respecting the Trust Fund Assets is
not known at the time the related Series of Securities initially is offered,
more general information of the nature described below will be provided in the
related Prospectus Supplement, and specific information will be set forth in a
report on Form 8-K to be filed with the Securities and Exchange Commission
within fifteen days after the initial issuance of such Securities (the 'Detailed
Description'). A maximum of 5% of the Trust Fund Assets as they will be
constituted at the time that the applicable Detailed Description is filed will
deviate in any material respect from the Trust Fund Asset pool characteristics
(other than the aggregate number or amount of Loans) described in the related
Prospectus Supplement. A copy of the Agreement with respect to each Series of
Securities will be attached to the Form 8-K and will be available for inspection
at the corporate trust office of the Trustee specified in the related Prospectus
Supplement. A schedule of the Loans relating to such Series will be attached to
the Agreement delivered to the Trustee upon delivery of the Securities.
 
THE LOANS
 
     General. Loans will consist of Single Family Loans, Multifamily Loans, Home
Equity Loans or Home Improvement Contracts. For purposes hereof, 'Home Equity
Loans' includes 'Closed-End Loans' and 'Revolving Credit Line Loans'. If so
specified, the Loans may include cooperative apartment loans ('Cooperative
Loans') secured by security interests in shares issued by private, non-profit,
cooperative housing corporations ('Cooperatives') and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in such Cooperatives' buildings. As more fully described in the
related Prospectus Supplement, the Loans may be 'conventional' loans or loans
that are insured or guaranteed by a governmental agency such as the FHA or VA.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Loans in a Pool will have monthly payments due on the first, tenth, fifteenth,
twentieth or twenty-fifth day of each month. The payment terms of the Loans to
be included in a Trust Fund will be described in the related Prospectus
Supplement and may include any of the following features (or combination
thereof), all as described below or in the related Prospectus Supplement:
 
          (a) Interest may be payable at a fixed rate, a rate adjustable from
     time to time in relation to an index (which will be specified in the
     related Prospectus Supplement), a rate that is fixed for a period of time
     or under certain circumstances and is followed by an adjustable rate, a
     rate that otherwise varies from time to time, a rate that is 'stepped-up'
     or a rate that is convertible from an adjustable rate to a fixed rate.
     Changes to an adjustable rate may be subject to periodic limitations,
     maximum rates, minimum rates or a combination of such limitations. Accrued
     interest may be deferred and added to the principal of a Loan for such
     periods and under such circumstances as may be specified in the related
     Prospectus Supplement. Loans may provide for the payment of interest at a
     rate lower than the specified interest rate borne by such Loan (the 'Loan
     Rate') for a period of time or for the life of the Loan, and the amount of
     any difference may be contributed from funds supplied by the seller of the
     Property or another source.
 
                                       23

<PAGE>
          (b) Principal may be payable on a level debt service basis to fully
     amortize the Loan over its term, may be calculated on the basis of an
     assumed amortization schedule that is significantly longer than the
     original term to maturity or on an interest rate that is different from the
     Loan Rate or may not be amortized during all or a portion of the original
     term. Payment of all or a substantial portion of the principal may be due
     on maturity ('balloon payment'). Principal may include interest that has
     been deferred and added to the principal balance of the Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the Loan, may increase over a specified period of time or may
     change from period to period. Loans may include limits on periodic
     increases or decreases in the amount of monthly payments and may include
     maximum or minimum amounts of monthly payments.
 
          (d) Prepayments of principal may be subject to a prepayment fee, which
     may be fixed for the life of the Loan or may decline over time, and may be
     prohibited for the life of the Loan or for certain periods ('lockout
     periods'). Certain Loans may permit prepayments after expiration of the
     applicable lockout period and may require the payment of a prepayment fee
     in connection with any such subsequent prepayment. Other Loans may permit
     prepayments without payment of a fee unless the prepayment occurs during
     specified time periods. The Loans may include 'due on sale' clauses which
     permit the mortgagee to demand payment of the entire Loan in connection
     with the sale or certain transfers of the related Property. Other Loans may
     be assumable by persons meeting the then applicable underwriting standards
     of the related Seller.
 
     A Trust Fund may contain certain Loans ('Buydown Loans') that include
provisions whereby a third party partially subsidizes the monthly payments of
the borrowers on such Loans during the early years of such Loans, the difference
to be made up from a fund (a 'Buydown Fund') contributed by such third party at
the time of origination of the Loan. A Buydown Fund will be in an amount equal
either to the discounted value or full aggregate amount of future payment
subsidies. The underlying assumption of buydown plans is that the income of the
borrower will increase during the buydown period as a result of normal increases
in compensation and inflation, so that the borrower will be able to meet the
full loan payments at the end of the buydown period. To the extent that this
assumption as to increased income is not fulfilled, the possibility of defaults
on Buydown Loans is increased. The related Prospectus Supplement will contain
information with respect to any Buydown Loan concerning limitations on the
interest rate paid by the borrower initially, on annual increases in the
interest rate and on the length of the buydown period.
 
     The real property which secures repayment of the Loans is referred to as
the 'Mortgaged Properties'. Home Improvement Contracts may, and the other Loans
will, be secured by mortgages or deeds of trust or other similar security
instruments creating a lien on a Mortgaged Property. In the case of Home Equity
Loans and the Home Improvement Contracts liens generally will be subordinated to
one or more senior liens on the related Mortgaged Properties as described in the
related Prospectus Supplement. As specified in the related Prospectus
Supplement, Home Improvement Contracts may be unsecured or secured by purchase
money security interests in the Home Improvements financed thereby. If so
specified in the related Prospectus Supplement, the Home Equity Loans and the
Home Improvement Contracts may include Loans (primarily for home improvement or
debt consolidation purposes) that are in amounts in excess of the value of the
related Mortgaged Properties at the time of origination. The Mortgaged
Properties and the Home Improvements are collectively referred to herein as the
'Properties'. The Properties may be located in any one of the fifty states, the
District of Columbia, Guam, Puerto Rico or any other territory of the United
States.
 
     Loans with certain Loan-to-Value Ratios and/or certain principal balances
may be covered wholly or partially by primary mortgage guaranty insurance
policies (each, a 'Primary Mortgage Insurance Policy'). The existence, extent
and duration of any such coverage will be described in the applicable Prospectus
Supplement.
 
     The aggregate principal balance of Loans secured by Properties that are
owner-occupied will be disclosed in the related Prospectus Supplement. Unless
otherwise specified in the related Prospectus Supplement, the sole basis for a
representation that a given percentage of the Loans is secured by Single Family
Properties that are owner-occupied will be either (i) the making of a
representation by the borrower at origination of the Loan either that the
underlying 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 Property as a primary
residence or (ii) a finding that the address of the underlying Property is the
borrower's mailing address.
 
                                       24

<PAGE>
     Single Family Loans. The Mortgaged Properties relating to Single Family
Loans will consist of detached or semi-detached one- to four-family dwelling
units, townhouses, rowhouses, individual condominium units, individual units in
planned unit developments, manufactured housing that is permanently affixed and
treated as real property under local law, security interests in shares issued by
cooperative housing corporations, and certain other dwelling units ('Single
Family Properties'). Single Family Properties may include vacation and second
homes, investment properties and leasehold interests. In the case of leasehold
interests, the remaining term of the leasehold and any sublease is at least as
long as the remaining term on the Loan, unless otherwise specified in the
related Prospectus Supplement.
 
     Multifamily Loans. Mortgaged Properties which secure Multifamily Loans may
include small multifamily residential properties such as rental apartment
buildings or projects containing five to fifty residential units, including
mid-rise and garden apartments. Certain of the Multifamily Loans may be secured
by apartment buildings owned by Cooperatives. In such cases, the Cooperative
owns all the apartment units in the building and all common areas. The
Cooperative is owned by tenant-stockholders who, through ownership of stock,
shares or membership certificates in the corporation, receive proprietary leases
or occupancy agreements which confer exclusive rights to occupy specific
apartments or units. Generally, a tenant-stockholder of a Cooperative must make
a monthly payment to the Cooperative representing such tenant-stockholder's pro
rata share of the Cooperative's payments for its mortgage loan, real property
taxes, maintenance expenses and other capital or ordinary expenses. Those
payments are in addition to any payments of principal and interest the tenant-
stockholder must make on any loans to the tenant-stockholder secured by its
shares in the Cooperative. The Cooperative will be directly responsible for
building management and, in most cases, payment of real estate taxes and hazard
and liability insurance. A Cooperative's ability to meet debt service
obligations on a Multifamily Loan, as well as all other operating expenses, will
be dependent in large part on the receipt of maintenance payments from the
tenant-stockholders, as well as any rental income from units the Cooperative
might control. Unanticipated expenditures may in some cases have to be paid by
special assessments on the tenant-stockholders.
 
     Home Equity Loans. The Mortgaged Properties relating to Home Equity Loans
will consist of Single Family Properties. As more fully described in the related
Prospectus Supplement, interest on each Revolving Credit Line Loan, excluding
introductory rates offered from time to time during promotional periods, is
computed and payable monthly on the average daily outstanding principal balance
of such Loan. Principal amounts on a Revolving Credit Line Loan may be drawn
down (up to a maximum amount as set forth in the related Prospectus Supplement)
or repaid under each Revolving Credit Line Loan from time to time, but may be
subject to a minimum periodic payment. Except to the extent provided in the
related Prospectus Supplement, the Trust Fund will not include any amounts
borrowed under a Revolving Credit Line Loan after the Cut-off Date. The full
amount of a Closed-End Loan is advanced at the inception of the Loan and
generally is repayable in equal (or substantially equal) installments of an
amount to fully amortize such Loan at its stated maturity. Except to the extent
provided in the related Prospectus Supplement, the original terms to stated
maturity of Closed-End Loans will not exceed 360 months. Under certain
circumstances, under either a Revolving Credit Line Loan or a Closed-End Loan, a
borrower may choose an interest only payment option and is obligated to pay only
the amount of interest which accrues on the Loan during the billing cycle. An
interest only payment option may be available for a specified period before the
borrower must begin paying at least the minimum monthly payment of a specified
percentage of the average outstanding balance of the Loan.
 
     Home Improvement Contracts. The Trust Fund Assets for a Series of
Securities may consist, in whole or in part, of Home Improvement Contracts
originated by a home improvement contractor, a thrift or a commercial mortgage
banker in the ordinary course of business. The Home Improvements securing the
Home Improvement Contracts may include, but are not limited to, replacement
windows, house siding, new roofs, swimming pools, spas, kitchen and bathroom
remodeling goods, solar heating panels and other exterior and interior
renovations and general remodeling projects. As specified in the related
Prospectus Supplement, the Home Improvement Contracts will either be unsecured
or secured by mortgages on Single Family Properties which are generally
subordinate to other mortgages on the same Property, or secured by purchase
money security interests in the Home Improvements financed thereby. Except as
otherwise specified in the related Prospectus Supplement, the Home Improvement
Contracts will be fully amortizing and may have fixed interest rates or
adjustable interest rates and may provide for other payment characteristics as
described below and in the related Prospectus Supplement. The initial
Loan-to-Value Ratio of a Home Improvement Contract is computed in the manner
described in the related Prospectus Supplement. See 'Risk Factors -- Home
Improvement Contracts and Home

     Additional Information. Each Prospectus Supplement will contain
information, as of the date of such Prospectus Supplement and to the extent then
specifically known to the Depositor, with respect to the Loans contained in the
related Pool, including (i) the aggregate outstanding principal balance and the
average outstanding principal balance of the Loans as of the applicable Cut-off
Date, (ii) the type of property securing the Loan (e.g., single family
residences, individual units in condominium apartment buildings, small multi-
family properties, other real property or Home Improvements), (iii) the original
terms to maturity of the Loans, (iv) the largest principal balance and the
smallest principal balance of any of the Loans, (v) the earliest origination
date and latest maturity date of any of the Loans, (vi) the Loan-to-Value Ratios
or Combined Loan-to-Value Ratios, as applicable, of the Loans, (vii) the Loan
Rates or annual percentage rates ('APR') or range of Loan Rates or APR's borne
by the Loans, (viii) the maximum and minimum per annum Loan Rates and (ix) the
geographical location of the Loans. If specific information respecting the Loans
is not known to the Depositor at the time the related Securities are initially
offered, more general information of the nature described above will be provided
in the related Prospectus Supplement, and specific information will be set forth
in the Detailed Description.
 
     Unless otherwise specified in the related Prospectus Supplement, the
'Loan-to-Value Ratio' of a Loan at any given time is the fraction, expressed as
a percentage, the numerator of which is the original principal balance of the
related Loan and the denominator of which is the Collateral Value of the related
Property. Unless otherwise specified in the related Prospectus Supplement, the
'Combined Loan-to-Value Ratio' of a Loan at any given time is the ratio,
expressed as a percentage, of (i) the sum of (a) the original principal balance
of the Loan (or, in the case of a Revolving Credit Line Loan, the maximum amount
thereof available at origination) and (b) the outstanding principal balance at
the date of origination of the Loan of any senior mortgage loan(s) or, in the
case of any open-ended senior mortgage loan, the maximum available line of
credit with respect to such mortgage loan at origination, regardless of any
lesser amount actually outstanding at the date of origination of the Loan, to
(ii) the Collateral Value of the related Property. Unless otherwise specified in
the related Prospectus Supplement, the 'Collateral Value' of the Property, other
than with respect to certain Loans the proceeds of which were used to refinance
an existing mortgage loan (each, a 'Refinance Loan'), is the lesser of (a) the
appraised value determined in an appraisal obtained by the originator at
origination of such Loan and (b) the sales price for such Property. In the case
of Refinance Loans, the 'Collateral Value' of the related Property is generally
the appraised value thereof determined in an appraisal obtained at the time of
refinancing.
 
     No assurance can be given that values of the Properties have remained or
will remain at their levels on the dates of origination of the related Loans. If
the residential real estate market should experience an overall decline in
property values such that the sum of the outstanding principal balances of the
Loans and any primary or secondary financing on the Properties, as applicable,
in a particular Pool become equal to or greater than the value of the
Properties, the actual rates of delinquencies, foreclosures and losses could be
higher than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions and other factors (which may or may not
affect real property values) may affect the timely payment by borrowers of
scheduled payments of principal and interest on the Loans and, accordingly, the
actual rates of delinquencies, foreclosures and losses with respect to any Pool.
To the extent that such losses are not covered by subordination provisions or
alternative arrangements, such losses will be borne, at least in part, by the
holders of the Securities of the related Series.
 
SUBSTITUTION OF TRUST FUND ASSETS
 
     Substitution of Trust Fund Assets will be permitted in the event of
breaches of representations and warranties with respect to any original Trust
Fund Asset or in the event certain documentation with respect to any Trust Fund
Asset is determined by the Trustee to be incomplete. See 'Loan
Program -- Representations by Sellers; Repurchases'. The period during which
such substitution will be permitted generally will be indicated in the related
Prospectus Supplement.

                                USE OF PROCEEDS
 
     The net proceeds to be received from the sale of the Securities will be
applied by the Depositor to the purchase of Trust Fund Assets or will be used by
the Depositor for general corporate purposes. The Depositor expects to sell
Securities in Series from time to time, but the timing and amount of offerings
of Securities will depend on a number of factors, including the volume of Trust
Fund Assets acquired by the Depositor, prevailing interest rates, availability
of funds and general market conditions.
 
                                 THE DEPOSITOR
 
     IndyMac ABS, Inc., a Delaware corporation (the 'Depositor'), was
incorporated in April 1998 for the limited purpose of acquiring, owning and
transferring mortgage and mortgage related assets and selling interests therein
or bonds secured thereby. The Depositor is a limited purpose finance subsidiary
of IndyMac, Inc., a Delaware corporation. The Depositor maintains its principal
office at 155 North Lake Avenue, Pasadena, California 91101. Its telephone
number is (800) 669-2300.
 
     Neither the Depositor nor any of the Depositor's affiliates will insure or
guarantee distributions on the Securities of any Series.
 
                                  LOAN PROGRAM
 
     The Loans will have been purchased by the Depositor, either directly or
through affiliates, from Sellers. Unless otherwise specified in the related
Prospectus Supplement, the Loans so acquired by the Depositor will have been
originated in accordance with the underwriting criteria specified below under
'Underwriting Standards'.
 
UNDERWRITING STANDARDS
 
     Underwriting standards are applied by or on behalf of a lender to evaluate
the borrower's credit standing and repayment ability, and the value and adequacy
of the related Property as collateral. In general, a prospective borrower
applying for a Loan is required to fill out a detailed application designed to
provide to the underwriting officer pertinent credit information, including the
principal balance and payment history with respect to any senior mortgage, if
any, which, unless otherwise specified in the related Prospectus Supplement,
will be verified by the related Seller. As part of the description of the
borrower's financial condition, the borrower generally is required to provide a
current list of assets and liabilities and a statement of income and expenses,
as well as an authorization to apply for a credit report which summarizes the
borrower's credit history with local merchants and lenders and any record of
bankruptcy. In most cases, an employment verification is obtained from an
independent source (typically the borrower's employer) which verification
reports, among other things, the length of employment with that organization and
the borrower's current salary. If a prospective borrower is self-employed, the
borrower may be required to submit copies of signed tax returns. The borrower
may also be required to authorize verification of deposits at financial
institutions where the borrower has demand or savings accounts.
 
     Unless otherwise specified in the related Prospectus Supplement, in
determining the adequacy of the property to be used as collateral, an appraisal
will generally be made of each property considered for financing. The appraiser
is generally required to inspect the property, issue a report on its condition
and, if applicable, verify construction, if new, has been completed. The
appraisal is generally based on the market value of comparable homes, the
estimated rental income (if considered applicable by the appraiser) and the cost
of replacing the home. 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.
 
     The maximum loan amount will vary depending upon a borrower's credit grade
and loan program but will not generally exceed $1,000,000. Variations in maximum
loan amount limits will be permitted based on compensating factors. Compensating
factors may generally include, to the extent specified in the related Prospectus
Supplement, low loan-to-value ratio, low debt-to-income ratio, stable
employment, favorable credit history and the nature of the underlying first
mortgage loan, if applicable.
 
     Each Seller's underwriting standards will generally permit loans with
loan-to-value ratios at origination of up to 100% depending on the loan program,
type and use of the property, creditworthiness of the borrower and
 
                                       27
 <PAGE>
<PAGE>
debt-to-income ratio. If so specified in the related Prospectus Supplement, a
Seller's underwriting criteria may permit loans with loan-to-value ratios at
origination in excess of 100%, such as for debt consolidation or home
improvement purposes. In addition, if so specified in the related Prospectus
Supplement, a Seller's underwriting criteria may permit unsecured loans for home
improvement purposes. Loan-to-value ratios may not be evaluated in the case of
Title I Loans.
 
     After obtaining all applicable employment, credit and property information,
the related Seller may use a debt-to-income ratio to assist in determining
whether the prospective borrower has sufficient monthly income available to
support the payments of principal and interest on the mortgage loan in addition
to other monthly credit obligations. The 'debt-to-income ratio' is the ratio of
the borrower's total monthly payments to the borrower's gross monthly income.
The maximum monthly debt-to-income ratio will vary depending upon a borrower's
credit grade and loan program. Variations in the monthly debt-to-income ratio
limit will be permitted based on compensating factors to the extent specified in
the related Prospectus Supplement.
 
     In the case of a Loan secured by a leasehold interest in real property, the
title to which is held by a third party lessor, the related Seller will, unless
otherwise specified in the related Prospectus Supplement, represent and warrant,
among other things, that the remaining term of the lease and any sublease is at
least as long as the remaining term on the Loan.
 
     Certain of the types of Loans that may be included in a Trust Fund are
recently developed and may involve additional uncertainties not present in
traditional types of loans. For example, certain of such Loans may provide for
escalating or variable payments by the borrower. These types of Loans are
underwritten on the basis of a judgment that the borrowers have the ability to
make the monthly payments required initially. In some instances, a borrower's
income may not be sufficient to permit continued loan payments as such payments
increase. These types of Loans may also be underwritten primarily upon the basis
of Loan-to-Value Ratios or other favorable credit factors.
 
QUALIFICATIONS OF SELLERS
 
     Each Seller will be required to satisfy the following qualifications. Each
Seller must be an institution experienced in originating and servicing loans of
the type contained in the related Pool in accordance with accepted practices and
prudent guidelines, and must maintain satisfactory facilities to originate and
service those loans. Unless otherwise specified in the related Prospectus
Supplement, each Seller must be (i) a seller/servicer approved by either the
Federal National Mortgage Association ('FNMA') or the Federal Home Loan Mortgage
Corporation ('FHLMC') and (ii) a mortgagee approved by HUD or an institution the
deposit accounts of which are insured by the Federal Deposit Insurance
Corporation (the 'FDIC').
 
REPRESENTATIONS BY SELLERS; REPURCHASES
 
     Each Seller will have made representations and warranties in respect of the
Loans sold by such Seller and evidenced by all, or a part, of a Series of
Securities. Such representations and warranties may include, among other things:
(i) that title insurance (or in the case of Properties located in areas where
such policies are generally not available, an attorney's certificate of title)
and any required hazard insurance policy were effective at origination of each
Loan, other than Cooperative Loans and certain Home Equity Loans, and that each
policy (or certificate of title as applicable) remained in effect on the date of
purchase of the Loan from the Seller by or on behalf of the Depositor; (ii) that
the Seller had good title to each such Loan and such Loan was subject to no
offsets, defenses, counterclaims or rights of rescission except to the extent
that any buydown agreement may forgive certain indebtedness of a borrower;
(iii) that each Loan, other than Cooperative Loans, constituted a valid lien on,
or a perfected security interest with respect to, the Property (subject only to
permissible liens disclosed, if applicable, title insurance exceptions, if
applicable, the liens of nondelinquent current real property taxes and
assessments, if applicable, liens arising under federal, state or local laws
relating to hazardous wastes or hazardous substances, if applicable, any liens
for common charges, if applicable, and certain other exceptions described in the
Agreement); (iv) that there were no delinquent tax or assessment liens against
the Property; (v) that no required payment on a Loan was delinquent more than
the number of days specified in the related Prospectus Supplement; and (vi) that
each Loan was made in compliance with, and is enforceable under, all applicable
local, state and federal laws and regulations in all material respects.
 
                                       28
 <PAGE>
<PAGE>
     If so specified in the related Prospectus Supplement, the representations
and warranties of a Seller in respect of a Loan will be made not as of the
Cut-off Date but as of the date on which such Seller sold the Loan to the
Depositor or one of its affiliates. Under such circumstances, a substantial
period of time may have elapsed between the sale date and the date of initial
issuance of the Series of Securities evidencing an interest in such Loan. Since
the representations and warranties of a Seller do not address events that may
occur following the sale of a Loan by such Seller, its repurchase obligation
described below will not arise if the relevant event that would otherwise have
given rise to such an obligation with respect to a Loan occurs after the date of
sale of such Loan by such Seller to the Depositor or its affiliates. However,
the Depositor will not include any Loan in the Trust Fund for any Series of
Securities if anything has come to the Depositor's attention that would cause it
to believe that the representations and warranties of a Seller will not be
accurate and complete in all material respects in respect of such Loan as of the
date of initial issuance of the related Series of Securities. If the Master
Servicer is also a Seller of Loans with respect to a particular Series of
Securities, such representations will be in addition to the representations and
warranties made by the Master Servicer in its capacity as a Master Servicer.
 
     The Master Servicer or the Trustee, if the Master Servicer is the Seller,
will promptly notify the relevant Seller of any breach of any representation or
warranty made by it in respect of a Loan which materially and adversely affects
the interests of the Securityholders in such Loan. Unless otherwise specified in
the related Prospectus Supplement, if such Seller cannot cure any such breach on
or prior to the business day after the first Determination Date which is more
than 90 days after such Seller's receipt of notice from the Master Servicer or
the Trustee, as the case may be, then such Seller will be obligated either (i)
to repurchase such Loan from the Trust Fund at a price (the 'Purchase Price')
equal to 100% of the unpaid principal balance thereof as of the date of the
repurchase plus accrued interest thereon to the scheduled monthly payment date
for such Loan in the month following the month of repurchase at the Loan Rate
(less any Advances or amount payable as related servicing compensation if the
Seller is the Master Servicer) or (ii) substitute for such Loan a replacement
loan that satisfies the criteria specified in the related Prospectus Supplement;
provided, however, that such Seller will not be obligated to make any such
repurchase or substitution (or cure such breach) if such breach constitutes
fraud in the origination of the affected Loan and such Seller did not have
knowledge of such fraud. If a REMIC election is to be made with respect to a
Trust Fund, unless otherwise specified in the related Prospectus Supplement, the
Master Servicer or a holder of the related residual certificate generally will
be obligated to pay any prohibited transaction tax which may arise in connection
with any such repurchase or substitution and the Trustee must have received a
satisfactory opinion of counsel that such repurchase or substitution will not
cause the Trust Fund to lose its status as a REMIC or otherwise subject the
Trust Fund to a prohibited transaction tax. The Master Servicer may be entitled
to reimbursement for any such payment from the assets of the related Trust Fund
or from any holder of the related residual certificate. See 'Description of the
Securities -- General'. Except in those cases in which the Master Servicer is
the Seller, the Master Servicer will be required under the relevant Agreement to
enforce this obligation for the benefit of the Trustee and the holders of the
Securities, following the practices it would employ in its good faith business
judgment were it the owner of such Loan. This repurchase or substitution
obligation will constitute the sole remedy available to holders of Securities or
the Trustee for a breach of representation by a Seller.
 
     Neither the Depositor nor the Master Servicer (unless the Master Servicer
is a Seller) will be obligated to purchase or substitute a Loan if a Seller
defaults on its obligation to do so, and no assurance can be given that Sellers
will carry out their respective repurchase or substitution obligations with
respect to Loans.
 
                         DESCRIPTION OF THE SECURITIES
 
     Each Series of Certificates will be issued pursuant to separate agreements
(each, a 'Pooling and Servicing Agreement' or a 'Trust Agreement') among the
Depositor, the Master Servicer and the Trustee. A form of Pooling and Servicing
Agreement and Trust Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. Each Series of Notes will be
issued pursuant to an indenture (the 'Indenture') between the related Trust Fund
and the entity named in the related Prospectus Supplement as trustee (the
'Trustee') with respect to such Series, and the related Loans will be serviced
by the Master Servicer pursuant to a Master Servicing Agreement. A form of

provisions of each Agreement will vary depending upon the nature of the
Securities to be issued thereunder and the nature of the related Trust Fund. The
following are descriptions of the material provisions which may appear in each
Agreement. The descriptions are subject to, and are qualified in their entirety
by reference to, all of the provisions of the Agreement for each Series of
Securities and the applicable Prospectus Supplement. The Depositor will provide
a copy of the Agreement (without exhibits) relating to any Series without charge
upon written request of a holder of record of a Security of such Series
addressed to IndyMac ABS, Inc., 155 North Lake Avenue, Pasadena, California
91101, Attention: Secondary Marketing.
 
GENERAL
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities of each Series will be issued in book-entry or fully registered form,
in the authorized denominations specified in the related Prospectus Supplement,
will, in the case of Certificates, evidence specified beneficial ownership
interests in, and in the case of Notes, be secured by, the assets of the related
Trust Fund created pursuant to each Agreement and will not be entitled to
payments in respect of the assets included in any other Trust Fund established
by the Depositor. Unless otherwise specified in the related Prospectus
Supplement, the Securities will not represent obligations of the Depositor or
any affiliate of the Depositor. Certain of the Loans may be guaranteed or
insured as set forth in the related Prospectus Supplement. Each Trust Fund will
consist of, to the extent provided in the related Agreement, (i) the Trust Fund
Assets, as from time to time are subject to the related Agreement (exclusive of
any amounts specified in the related Prospectus Supplement ('Retained
Interest')), including all payments of interest and principal received with
respect to the Loans after the Cut-off Date (to the extent not applied in
computing the principal balance of such Loans as of the Cut-off Date (the
'Cut-off Date Principal Balance')); (ii) such assets as from time to time are
required to be deposited in the related Security Account, as described below
under 'The Agreements -- Payments on Loans; Deposits to Security Account';
(iii) property which secured a Loan and which is acquired on behalf of the
Securityholders by foreclosure or deed in lieu of foreclosure and (iv) any
insurance policies or other forms of credit enhancement required to be
maintained pursuant to the related Agreement. If so specified in the related
Prospectus Supplement, a Trust Fund may also include one or more of the
following: reinvestment income on payments received on the Trust Fund Assets, a
Reserve Account, a mortgage pool insurance policy, a special hazard insurance
policy, a bankruptcy bond, one or more letters of credit, a surety bond,
guaranties or similar instruments.
 
     Each Series of Securities will be issued in one or more classes. Each class
of Certificates of a Series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on, and each class of Notes of a Series will be secured by, the related Trust
Fund Assets. A Series of Securities may include one or more classes that are
senior in right to payment to one or more other classes of Securities of such
Series. Certain Series or classes of Securities may be covered by insurance
policies, surety bonds or other forms of credit enhancement, in each case as
described under 'Credit Enhancement' herein and in the related Prospectus
Supplement. One or more classes of Securities of a Series may be entitled to
receive distributions of principal, interest or any combination thereof.
Distributions on one or more classes of a Series of Securities may be made prior
to one or more other classes, after the occurrence of specified events, in
accordance with a schedule or formula or on the basis of collections from
designated portions of the related Trust Fund Assets, in each case as specified
in the related Prospectus Supplement. The timing and amounts of such
distributions may vary among classes or over time as specified in the related
Prospectus Supplement.
 
     Distributions of principal and interest (or, where applicable, of principal
only or interest only) on the related Securities will be made by the Trustee on
each Distribution Date (i.e., monthly, quarterly, semi-annually or at such other
intervals and on the dates as are specified in the related Prospectus
Supplement) in proportion to the percentages specified in the related Prospectus
Supplement. Distributions will be made to the persons in whose names the
Securities are registered at the close of business on the dates specified in the
related Prospectus Supplement (each, a 'Record Date'). Distributions will be
made in the manner specified in the related Prospectus Supplement to the persons
entitled thereto at the address appearing in the register maintained for holders
of Securities (the 'Security Register'); provided, however, that the final
distribution in retirement of the Securities will be made only upon presentation
and surrender of the Securities at the office or agency of the Trustee or other
person specified in the notice to Securityholders of such final distribution.
 
                                       30

     The Securities will be freely transferable and exchangeable at the
Corporate Trust Office of the Trustee as set forth in the related Prospectus
Supplement. No service charge will be made for any registration of exchange or
transfer of Securities of any Series, but the Trustee may require payment of a
sum sufficient to cover any related tax or other governmental charge.
 
     Under current law, the purchase and holding of certain classes of
Securities by or on behalf of any employee benefit plan or other retirement
arrangement (including individual retirement accounts and annuities, Keogh plans
and collective investment funds in which such plans, accounts or arrangements
are invested) subject to provisions of ERISA or the Code may result in
prohibited transactions, within the meaning of ERISA and the Code, or may
subject the Trustee, the Master Servicer or the Depositor to obligations or
liabilities in addition to those undertaken in the related Agreement. See 'ERISA
Considerations'. Under current law, the transfer of Securities of such a class
will not be registered unless the transferee (i) represents that it is not, and
is not purchasing on behalf of, any such plan, account or arrangement or (ii)
provides an opinion of counsel satisfactory to the Trustee and the Depositor
that the purchase of Securities of such a class by or on behalf of such plan,
account or arrangement is permissible under applicable law and will not subject
the Trustee, the Master Servicer or the Depositor to any obligation or liability
in addition to those undertaken in the Agreements.
 
     As to each Series, an election may be made to treat the related Trust Fund
or designated portions thereof either as a REMIC or as a FASIT. The related
Prospectus Supplement will specify whether a REMIC or FASIT election is to be
made. Alternatively, the Agreement for a Series may provide that a REMIC or
FASIT election may be made at the discretion of the Depositor or the Master
Servicer and may only be made if certain conditions are satisfied. As to any
such Series, the terms and provisions applicable to the making of a REMIC or
FASIT election will be set forth in the related Prospectus Supplement. If a
REMIC election is made with respect to a Series, one of the classes will be
designated as evidencing the sole class of 'residual interests' in the related
REMIC, as defined in the Code. All other classes of Securities in such a Series
will constitute 'regular interests' in the related REMIC, as defined in the
Code. If a FASIT election is made with respect to a Series, one of the classes
will be designated as the ownership interest, as defined in the Code. All other
classes of Securities in such a Series will constitute 'regular interests' in
the related FASIT, as defined in the Code. As to each Series with respect to
which a REMIC or FASIT election is to be made, the Master Servicer or a holder
of the related residual in the case of a REMIC, and the holder of the related
ownership interest in the case of a FASIT, certificate will be obligated to take
all actions required in order to comply with applicable laws and regulations and
will be obligated to pay any prohibited transaction taxes. The Master Servicer,
unless otherwise provided in the related Prospectus Supplement, will be entitled
to reimbursement for any such payment from the assets of the Trust Fund or from
any holder of the related residual certificate in the case of a REMIC, or, from
the holder of the related ownership interest in the case of a FASIT.
 
DISTRIBUTIONS ON SECURITIES
 
     General. In general, the method of determining the amount of distributions
on a particular Series of Securities will depend on the type of credit support,
if any, that is used with respect to such Series. See 'Credit Enhancement'. Set
forth below are descriptions of various methods that may be used to determine
the amount of distributions on the Securities of a particular Series. The
Prospectus Supplement for each Series of Securities will describe the method to
be used in determining the amount of distributions on the Securities of such
Series.
 
     Distributions allocable to principal and interest on the Securities will be
made by the Trustee out of, and only to the extent of, funds in the related
Security Account, including any funds transferred from any Reserve Account (a
'Reserve Account'). As between Securities of different classes and as between
distributions of principal (and, if applicable, between distributions of
Principal Prepayments, as defined below, and scheduled payments of principal)
and interest, distributions made on any Distribution Date will be applied as
specified in the related Prospectus Supplement. The Prospectus Supplement will
also describe the method for allocating distributions among Securities of a
particular class.
 
     Available Funds. All distributions on the Securities of each Series on each
Distribution Date will be made from the Available Funds described below, in
accordance with the terms described in the related Prospectus Supplement and
specified in the Agreement. 'Available Funds' for each Distribution Date will
generally equal the amount on deposit in the related Security Account on such
Distribution Date (net of related fees and expenses payable by the related Trust
Fund) other than amounts to be held therein for distribution on future
Distribution Dates.
 
                                       31
 <PAGE>
<PAGE>
     Distributions of Interest. Interest will accrue on the aggregate principal
balance of the Securities (or, in the case of Securities entitled only to
distributions allocable to interest, the aggregate notional amount) of each
class of Securities (the 'Class Security Balance') entitled to interest from the
date, at the pass-through rate or interest rate, as applicable (which in either
case may be a fixed rate or rate adjustable as specified in such Prospectus
Supplement), and for the periods specified in such Prospectus Supplement. To the
extent funds are available therefor, interest accrued during each such specified
period on each class of Securities entitled to interest (other than a class of
Securities that provides for interest that accrues, but is not currently
payable, referred to hereafter as 'Accrual Securities') will be distributable on
the Distribution Dates specified in the related Prospectus Supplement until the
aggregate Class Security Balance of the Securities of such class has been
distributed in full or, in the case of Securities entitled only to distributions
allocable to interest, until the aggregate notional amount of such Securities is
reduced to zero or for the period of time designated in the related Prospectus
Supplement. The original Class Security Balance of each Security will equal the
aggregate distributions allocable to principal to which such Security is
entitled. Distributions allocable to interest on each Security that is not
entitled to distributions allocable to principal will be calculated based on the
notional amount of such Security. The notional amount of a Security will not
evidence an interest in or entitlement to distributions allocable to principal
but will be used solely for convenience in expressing the calculation of
interest and for certain other purposes.
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Security were to accrue through the day immediately preceding
such Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate.
 
     With respect to any class of Accrual Securities, if specified in the
related Prospectus Supplement, any interest that has accrued but is not paid on
a given Distribution Date will be added to the aggregate Class Security Balance
of such class of Securities on that Distribution Date. Distributions of interest
on any class of Accrual Securities will commence only after the occurrence of
the events specified in such Prospectus Supplement. Prior to such time, the
beneficial ownership interest in the Trust Fund or the principal balance, as
applicable, of such class of Accrued Securities, as reflected in the aggregate
Class Security Balance of such class of Accrual Securities, will increase on
each Distribution Date by the amount of interest that accrued on such class of
Accrual Securities during the preceding interest accrual period but that was not
required to be distributed to such class on such Distribution Date. Any such
class of Accrual Securities will thereafter accrue interest on its outstanding
Class Security Balance as so adjusted.
 
     Distributions of Principal. The related Prospectus Supplement will specify
the method by which the amount of principal to be distributed on the Securities
on each Distribution Date will be calculated and the manner in which such amount
will be allocated among the classes of Securities entitled to distributions of
principal. The aggregate Class Security Balance of any class of Securities
entitled to distributions of principal generally will be the aggregate original
Class Security Balance of such class of Securities specified in such Prospectus
Supplement, reduced by all distributions reported to the holders of such
Securities as allocable to principal and, (i) in the case of Accrual Securities,
increased by all interest accrued but not then distributable on such Accrual
Securities and (ii) in the case of adjustable rate Securities, subject to the
effect of negative amortization, if applicable.
 
     If so provided in the related Prospectus Supplement, one or more classes of
Securities will be entitled to receive all or a disproportionate percentage of
the payments of principal which are received from borrowers in advance of their
scheduled due dates and are not accompanied by amounts representing scheduled
interest due after the month of such payments ('Principal Prepayments') in the
percentages and under the circumstances or for the periods specified in such
Prospectus Supplement. Any such allocation of Principal Prepayments to such
class or classes of Securities will have the effect of accelerating the
amortization of such Securities while increasing the interests evidenced by one
or more other classes of Securities in the Trust Fund. Increasing the interests
of the other classes of Securities relative to that of certain Securities is
intended to preserve the availability of the subordination provided by such
other Securities. See 'Credit Enhancement -- Subordination'.
 
     Unscheduled Distributions. If specified in the related Prospectus
Supplement, the Securities will be subject to receipt of distributions before
the next scheduled Distribution Date under the circumstances and in the manner
 
                                       32
 <PAGE>
<PAGE>
described below and in such Prospectus Supplement. If applicable, the Trustee
will be required to make such unscheduled distributions on the day and in the
amount specified in the related Prospectus Supplement if, due to substantial
payments of principal (including Principal Prepayments) on the Trust Fund
Assets, the Trustee or the Master Servicer determines that the funds available
or anticipated to be available from the Security Account and, if applicable, any
Reserve Account, may be insufficient to make required distributions on the
Securities on such Distribution Date. Unless otherwise specified in the related
Prospectus Supplement, the amount of any such unscheduled distribution that is
allocable to principal will not exceed the amount that would otherwise have been
required to be distributed as principal on the Securities on the next
Distribution Date. Unless otherwise specified in the related Prospectus
Supplement, the unscheduled distributions will include interest at the
applicable pass-through rate (if any) or interest rate (if any) on the amount of
the unscheduled distribution allocable to principal for the period and to the
date specified in such Prospectus Supplement.
 
ADVANCES
 
     To the extent provided in the related Prospectus Supplement, the Master
Servicer will be required to advance on or before each Distribution Date (from
its own funds, funds advanced by Sub-Servicers or funds held in the Security
Account for future distributions to the holders of Securities of the related
Series), an amount equal to the aggregate of payments of interest and/or
principal that were delinquent on the related Determination Date (as such term
is defined in the related Prospectus Supplement) and were otherwise not advanced
by any Sub-Servicer, subject to the Master Servicer's determination that such
advances may be recoverable out of late payments by borrowers, Liquidation
Proceeds, Insurance Proceeds or otherwise. In the case of Cooperative Loans, the
Master Servicer also may be required to advance any unpaid maintenance fees and
other charges under the related proprietary leases as specified in the related
Prospectus Supplement.
 
     In making Advances, the Master Servicer will endeavor to maintain a regular
flow of scheduled interest and principal payments to holders of the Securities,
rather than to guarantee or insure against losses. If Advances are made by the
Master Servicer from cash being held for future distribution to Securityholders,
the Master Servicer will replace such funds on or before any future Distribution
Date to the extent that funds in the applicable Security Account on such
Distribution Date would be less than the amount required to be available for
distributions to Securityholders on such date. Any Master Servicer funds
advanced will be reimbursable to the Master Servicer out of recoveries on the
specific Loans with respect to which such Advances were made (e.g., late
payments made by the related borrower, any related Insurance Proceeds,
Liquidation Proceeds or proceeds of any Loan purchased by the Depositor, a
Sub-Servicer or a Seller pursuant to the related Agreement). Advances by the
Master Servicer (and any advances by a Sub-Servicer) also will be reimbursable
to the Master Servicer (or Sub-Servicer) from cash otherwise distributable to
Securityholders (including the holders of Senior Securities) to the extent that
the Master Servicer determines that any such Advances previously made are not
ultimately recoverable as described above. To the extent provided in the related
Prospectus Supplement, the Master Servicer also will be obligated to make
Advances, to the extent recoverable out of Insurance Proceeds, Liquidation
Proceeds or otherwise, in respect of certain taxes and insurance premiums not
paid by borrowers on a timely basis. Funds so advanced are reimbursable to the
Master Servicer to the extent permitted by the related Agreement. The
obligations of the Master Servicer to make advances may be supported by a cash
advance reserve fund, a surety bond or other arrangement of the type described
herein under 'Credit Enhancement,' in each case as described in the related
Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, in the
event the Master Servicer or a Sub-Servicer fails to make a required Advance,
the Trustee will be obligated to make such Advance in its capacity as successor
servicer. If the Trustee makes such an Advance, it will be entitled to be
reimbursed for such Advance to the same extent and degree as the Master Servicer
or a Sub-Servicer is entitled to be reimbursed for Advances. See 'Description of
the Securities -- Distributions on Securities'.
 
REPORTS TO SECURITYHOLDERS
 
     Unless otherwise specified in the related Prospectus Supplement, prior to
or concurrently with each distribution on a Distribution Date the Master
Servicer or the Trustee will furnish to each Securityholder of record of the
related Series a statement setting forth, to the extent applicable to such
Series of Securities, among other things:

     the close of business on the Distribution Date;
 
          (xiii) the pass-through rate or interest rate, as applicable, as of

          (xiv) any amounts remaining under letters of credit, pool policies or
     other forms of credit enhancement.
 
     Where applicable, any amount set forth above may be expressed as a dollar
amount per single Security of the relevant class having the Percentage Interest

for any Series of Securities may include additional or other information of a
similar nature to that specified above.
 
     In addition, within a reasonable period of time after the end of each
calendar year, the Master Servicer or the Trustee will mail to each
Securityholder of record at any time during such calendar year a report (a) as
to the aggregate of amounts reported pursuant to (i) and (ii) above for such
calendar year or, in the event such person was a Securityholder of record during
a portion of such calendar year, for the applicable portion of such year and
(b) such other customary information as may be deemed necessary or desirable for
Securityholders to prepare their tax returns.
 
CATEGORIES OF CLASSES OF SECURITIES
 
     The Securities of any Series may be comprised of one or more classes. Such
classes, in general, fall into different categories. The following chart
identifies and generally defines certain of the more typical categories. The
Prospectus Supplement for a series of Securities may identify the classes which
comprise such Series by reference to the following categories.

CATEGORIES OF CLASSES                                              DEFINITION

                                                                PRINCIPAL TYPES
<S>                             <C>
Accretion Directed............  A class that receives principal payments from the accreted interest from
                                specified Accrual Securities. An Accretion Directed class also may receive
                                principal payments from principal paid on the underlying Trust Fund Assets for
                                the related Series.

Component Securities..........  A class consisting of 'Components'. The Components of a class of Component
                                Securities may have different principal and/or interest payment characteristics
                                but together constitute a single class. Each Component of a class of Component
                                Securities may be identified as falling into one or more of the categories in
                                this chart.

Notional Amount Securities....  A class having no principal balance and bearing interest on the related notional
                                amount. The notional amount is used for purposes of the determination of interest
                                distributions.

Planned Principal Class (also
  sometimes referred to as
  'PACs').....................  A class that is designed to receive principal payments using a predetermined
                                principal balance schedule derived by assuming two constant prepayment rates for
                                the underlying Trust Fund Assets. These two rates are the endpoints for the
                                'structuring range' for the Planned Principal Class. The Planned Principal
                                Classes in any Series of Securities may be subdivided into different categories
                                (e.g., Primary Planned Principal Classes, Secondary Planned Principal Classes and
                                so forth) having different effective structuring ranges and different principal
                                payment priorities. The structuring range for the Secondary Planned Principal
                                Categories of Classes of a Series of Securities will be narrower than that for
                                the Primary Planned Principal Class of such Series.

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

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

Strip.........................  A class that receives a constant proportion, or 'strip,' of the principal
                                payments on the underlying Trust Fund Assets.

Support Class (also sometimes
  referred to as 'companion
  classes')...................  A class that receives principal payments on any Distribution Date only if
                                scheduled payments have been made on specified Planned Principal Classes,
                                Targeted Principal Classes and/or Scheduled Principal Classes.

Targeted Principal Class (also
  sometimes referred to as
  'TACs').....................  A class that is designed to receive principal payments using a predetermined
                                principal balance schedule derived by assuming a single constant prepayment rate
                                for the underlying Trust Fund Assets.

                                                                 INTEREST TYPES
<S>                             <C>
Fixed Rate....................  A class with an interest rate that is fixed throughout the life of the class.

Floating Rate.................  A class with an interest rate that resets periodically based upon a designated
                                index and that varies directly with changes in such index.

Inverse Floating Rate.........  A class with an interest rate that resets periodically based upon a designated
                                index and that varies inversely with changes in such index.

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

Interest Only.................  A class that receives some or all of the interest payments made on the underlying
                                Trust Fund Assets and little or no principal. Interest Only classes have either a
                                nominal principal balance or a notional amount. A nominal principal balance
                                represents actual principal that will be paid on the class. It is referred to as
                                nominal since it is extremely small compared to other classes. A notional amount
                                is the amount used as a reference to calculate the amount of interest due on an
                                Interest Only class that is not entitled to any distributions in respect of
                                principal.

Principal Only................  A class that does not bear interest and is entitled to receive only distributions
                                in respect of principal.

Partial Accrual...............  A class that accretes a portion of the amount of accrued interest thereon, which
                                amount will be added to the principal balance of such class on each applicable
                                Distribution Date, with the remainder of such accrued interest to be distributed
                                currently as interest on such class. Such accretion may continue until a
                                specified event has occurred or until such Partial Accrual class is retired.

Accrual.......................  A class that accretes the amount of accrued interest otherwise distributable on
                                such class, which amount will be added as principal to the principal balance of
                                such class on each applicable Distribution Date. Such accretion may continue
                                until some specified event has occurred or until such Accrual class is retired.

INDICES APPLICABLE TO FLOATING RATE AND INVERSE FLOATING RATE CLASSES
 
LIBOR
 
     Unless otherwise specified in the related Prospectus Supplement, on the
LIBOR Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as LIBOR, the
Person designated in the related Agreement (the 'Calculation Agent') will
determine LIBOR in accordance with one of the two methods described below (which
method will be specified in the related Prospectus Supplement):
 
LIBO Method
 
     If using this method to calculate LIBOR, the Calculation Agent will
determine LIBOR by reference to the quotations set forth on the Reuters Screen
LIBO Page (as defined in the International Swap Dealers Association, Inc. Code
of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition),
offered by the principal London office of each of the designated reference banks
meeting the criteria set forth below (the 'Reference Banks') for making
one-month United States dollar deposits in leading banks in the London Interbank
market, as of 11:00 a.m. (London time) on such LIBOR Determination Date. In lieu
of relying on the quotations for those Reference Banks that appear at such time
on the Reuters Screen LIBO Page, the Calculation Agent will request each of the
Reference Banks to provide such offered quotations at such time.
 
                                       36
 <PAGE>
<PAGE>
     Under this method LIBOR will be established by the Calculation Agent on
each LIBOR Determination Date as follows:
 
          (a) If on any LIBOR Determination Date two or more Reference Banks
     provide such offered quotations, LIBOR for the next Interest Accrual Period
     shall be the arithmetic mean of such offered quotations (rounded upwards if
     necessary to the nearest whole multiple of 1/32%).
 
          (b) If on any LIBOR Determination Date only one or none of the
     Reference Banks provides such offered quotations, LIBOR for the next
     Interest Accrual Period (as such term is defined in the related Prospectus
     Supplement) shall be whichever is the higher of (i) LIBOR as determined on
     the previous LIBOR Determination Date or (ii) the Reserve Interest Rate.
     The 'Reserve Interest Rate' shall be the rate per annum which the
     Calculation Agent determines to be either (i) the arithmetic mean (rounded
     upwards if necessary to the nearest whole multiple of 1/32%) of the
     one-month United States dollar lending rates that New York City banks
     selected by the Calculation Agent are quoting, on the relevant LIBOR
     Determination Date, to the principal London offices of at least two of the
     Reference Banks to which such quotations are, in the opinion of the
     Calculation Agent, being so made or (ii) in the event that the Calculation
     Agent can determine no such arithmetic mean, the lowest one-month United
     States dollar lending rate which New York City banks selected by the
     Calculation Agent are quoting on such LIBOR Determination Date to leading
     European banks.
 
          (c) If on any LIBOR Determination Date for a class specified in the
     related Prospectus Supplement, the Calculation Agent is required but is
     unable to determine the Reserve Interest Rate in the manner provided in
     paragraph (b) above, LIBOR for the next Interest Accrual Period shall be
     LIBOR as determined on the preceding LIBOR Determination Date, or, in the
     case of the first LIBOR Determination Date, LIBOR shall be deemed to be the
     per annum rate specified as such in the related Prospectus Supplement.
 
     Each Reference Bank (i) shall be a leading bank engaged in transactions in
Eurodollar deposits in the international Eurocurrency market; (ii) shall not
control, be controlled by, or be under common control with the Calculation
Agent; and (iii) shall have an established place of business in London. If any
such Reference Bank should be unwilling or unable to act as such or if
appointment of any such Reference Bank is terminated, another leading bank
meeting the criteria specified above will be appointed.
 
BBA Method
 
     If using this method of determining LIBOR, the Calculation Agent will
determine LIBOR on the basis of the British Bankers' Association ('BBA')
'Interest Settlement Rate' for one-month deposits in United States dollars as
found on Telerate page 3750 as of 11:00 a.m. London time on each LIBOR
Determination Date. Interest Settlement Rates currently are based on rates
quoted by eight BBA designated banks as being, in the view of such banks, the
offered rate at which deposits are being quoted to prime banks in the London
interbank market. Such Interest Settlement Rates are calculated by eliminating
the two highest rates and the two lowest rates, averaging the four remaining
rates, carrying the result (expressed as a percentage) out to six decimal
places, and rounding to five decimal places.
 
     If on any LIBOR Determination Date, the Calculation Agent is unable to
calculate LIBOR in accordance with the method set forth in the immediately
preceding paragraph, LIBOR for the next Interest Accrual period shall be
calculated in accordance with the LIBOR method described above under 'LIBO
Method'.
 
     The establishment of LIBOR on each LIBOR Determination Date by the
Calculation Agent and its calculation of the rate of interest for the applicable
classes for the related Interest Accrual Period shall (in the absence of
manifest error) be final and binding.
 
COFI
 
     The Eleventh District Cost of Funds Index is designed to represent the
monthly weighted average cost of funds for savings institutions in Arizona,
California and Nevada that are member institutions of the Eleventh Federal Home
Loan Bank District (the 'Eleventh District'). The Eleventh District Cost of
Funds Index for a particular month reflects the interest costs paid on all types
of funds held by Eleventh District member institutions and is calculated by
dividing the cost of funds by the average of the total amount of those funds
outstanding at the end of that month and of the prior month and annualizing and
adjusting the result to reflect
 
                                       37
 <PAGE>
<PAGE>
the actual number of days in the particular month. If necessary, before these
calculations are made, the component figures are adjusted by the Federal Home
Loan Bank of San Francisco ('FHLBSF') to neutralize the effect of events such as
member institutions leaving the Eleventh District or acquiring institutions
outside the Eleventh District. The Eleventh District Cost of Funds Index is
weighted to reflect the relative amount of each type of funds held at the end of
the relevant month. The major components of funds of Eleventh District member
institutions are: (i) savings deposits, (ii) time deposits, (iii) FHLBSF
advances, (iv) repurchase agreements and (v) all other borrowings. Because the
component funds represent a variety of maturities whose costs may react in
different ways to changing conditions, the Eleventh District Cost of Funds Index
does not necessarily reflect current market rates.
 
     A number of factors affect the performance of the Eleventh District Cost of
Funds Index which may cause it to move in a manner different from indices tied
to specific interest rates, such as United States Treasury bills or LIBOR.
Because the liabilities upon which the Eleventh District Cost of Funds Index is
based were issued at various times under various market conditions and with
various maturities, the Eleventh District Cost of Funds Index may not
necessarily reflect the prevailing market interest rates on new liabilities of
similar maturities. Moreover, as stated above, the Eleventh District Cost of
Funds Index is designed to represent the average cost of funds for Eleventh
District savings institutions for the month prior to the month in which it is
due to be published. Additionally, the Eleventh District Cost of Funds Index may
not necessarily move in the same direction as market interest rates at all
times, since as longer term deposits or borrowings mature and are renewed at
prevailing market interest rates, the Eleventh District Cost of Funds Index is
influenced by the differential between the prior and the new rates on those
deposits or borrowings. In addition, movements of the Eleventh District Cost of
Funds Index, as compared to other indices tied to specific interest rates, may
be affected by changes instituted by the FHLBSF in the method used to calculate
the Eleventh District Cost of Funds Index.
 
     The FHLBSF publishes the Eleventh District Cost of Funds Index in its
monthly Information Bulletin. Any individual may request regular receipt by mail
of Information Bulletins by writing the Federal Home Loan Bank of San Francisco,
P.O. Box 7948, 600 California Street, San Francisco, California 94120, or by
calling (415) 616-1000. The Eleventh District Cost of Funds Index may also be
obtained by calling the FHLBSF at (415) 616-2600.
 
     The FHLBSF has stated in its Information Bulletin that the Eleventh
District Cost of Funds Index for a month 'will be announced on or near the last
working day' of the following month and also has stated that it 'cannot
guarantee the announcement' of such index on an exact date. So long as such
index for a month is announced on or before the tenth day of the second
following month, the interest rate for each class of Securities of a Series as
to which the applicable interest rate is determined by reference to an index
denominated as COFI (each, a class of 'COFI Securities') for the Interest
Accrual Period commencing in such second following month will be based on the
Eleventh District Cost of Funds Index for the second preceding month. If
publication is delayed beyond such tenth day, such interest rate will be based
on the Eleventh District Cost of Funds Index for the third preceding month.
 
     Unless otherwise specified in the related Prospectus Supplement, if on the
tenth day of the month in which any Interest Accrual Period commences for a
class of COFI Securities the most recently published Eleventh District Cost of
Funds Index relates to a month prior to the third preceding month, the index for
such current Interest Accrual Period and for each succeeding Interest Accrual
Period will, except as described in the next to last sentence of this paragraph,
be based on the National Monthly Median Cost of Funds Ratio to SAIF-Insured
Institutions (the 'National Cost of Funds Index') published by the Office of
Thrift Supervision (the 'OTS') for the third preceding month (or the fourth
preceding month if the National Cost of Funds Index for the third preceding
month has not been published on such tenth day of an Interest Accrual Period).
Information on the National Cost of Funds Index may be obtained by writing the
OTS at 1700 G Street, N.W., Washington, D.C. 20552 or calling (202) 906-6677,
and the current National Cost of Funds Index may be obtained by calling (202)
906-6988. If on any such tenth day of the month in which an Interest Accrual
Period commences the most recently published National Cost of Funds Index
relates to a month prior to the fourth preceding month, the applicable index for
such Interest Accrual Period and each succeeding Interest Accrual Period will be
based on LIBOR, as determined by the Calculation Agent in accordance with the
Agreement relating to such Series of Securities. A change of index from the
Eleventh District Cost of Funds Index to an alternative index will result in a
change in the index level, and, particularly if LIBOR is the alternative index,
could increase its volatility.

 <PAGE>
<PAGE>
     The establishment of COFI by the Calculation Agent and its calculation of
the rates of interest for the applicable classes for the related Interest
Accrual Period shall (in the absence of manifest error) be final and binding.
 
Treasury Index
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Treasury Index Determination Date (as such term is defined in the related
Prospectus Supplement) for each class of Securities of a Series as to which the
applicable interest rate is determined by reference to an index denominated as a
Treasury Index, the Calculation Agent will ascertain the Treasury Index for
Treasury securities of the maturity and for the period (or, if applicable, date)
specified in the related Prospectus Supplement. Unless otherwise specified in
the related Prospectus Supplement, the Treasury Index for any period means the
average of the yield for each business day during the period specified therein
(and for any date means the yield for such date), expressed as a per annum
percentage rate, on (i) U.S Treasury securities adjusted to the 'constant
maturity' (as further described below) specified in such Prospectus Supplement
or (ii) if no 'constant maturity' is so specified, U.S. Treasury securities
trading on the secondary market having the maturity specified in such Prospectus
Supplement, in each case as published by the Federal Reserve Board in its
Statistical Release No. H.15(519). Statistical Release No. H.15(519) is
published on Monday or Tuesday of each week and may be obtained by writing or
calling the Publications Department at the Board of Governors of the Federal
Reserve System, 21st and C Streets, Washington, D.C. 20551 (202) 452-3244. If
the Calculation Agent has not yet received Statistical Release No. H.15(519) for
such week, then it will use such Statistical Release from the immediately
preceding week.
 
     Yields on U.S. Treasury securities at 'constant maturity' are derived from
the U.S. Treasury's daily yield curve. This curve, which relates the yield on a
security to its time to maturity, is based on the closing market bid yields on
actively traded Treasury securities in the over-the-counter market. These market
yields are calculated from composites of quotations reported by five leading
U.S. Government securities dealers to the Federal Reserve Bank of New York. This
method provides a yield for a given maturity even if no security with that exact
maturity is outstanding. In the event that the Treasury Index is no longer
published, a new index based upon comparable data and methodology will be
designated in accordance with the Agreement relating to the particular Series of
Securities. The Calculation Agent's determination of the Treasury Index, and its
calculation of the rates of interest for the applicable classes for the related
Interest Accrual Period shall (in the absence of manifest error) be final and
binding.
 
Prime Rate
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Prime Rate Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as the Prime
Rate, the Calculation Agent will ascertain the Prime Rate for the related
Interest Accrual Period. Unless otherwise specified in the related Prospectus
Supplement, the Prime Rate for an Interest Accrual Period will be the 'Prime
Rate' as published in the 'Money Rates' section of The Wall Street Journal (or
if not so published, the 'Prime Rate' as published in a newspaper of general
circulation selected by the Calculation Agent in its sole discretion) on the
related Prime Rate Determination Date. If a prime rate range is given, then the
average of such range will be used. In the event that the Prime Rate is no
longer published, a new index based upon comparable data and methodology will be
designated in accordance with the Agreement relating to the particular Series of
Securities. The Calculation Agent's determination of the Prime Rate and its
calculation of the rates of interest for the related Interest Accrual Period
shall (in the absence of manifest error) be final and binding.
 
DERIVATIVE TRANSACTIONS
 
     If specified in the related Prospectus Supplement, a Trust Fund may enter
into privately negotiated, over-the-counter hedging transactions with various
counterparties, including interest rate swaps, caps, collars and floors
(collectively, 'Derivative Transactions') to effectively fix the rate of
interest that such Trust Fund pays on one or more borrowings or series of
borrowings. Trust Funds will use these Derivative Transactions as hedges and not
as speculative investments. Derivative Transactions involve an agreement between
two parties to exchange payments that are based, respectively, on variable and
fixed rates of interest and that are calculated on
 
                                       39
 <PAGE>
<PAGE>
the basis of a specified amount of principal for a specified period of time. Cap
and floor transactions involve an agreement between two parties in which the
first party agrees to make payments to the counterparty when a designated market
interest rate goes above (in the case of a cap) or below (in the case of a
floor) a designated level on predetermined dates or during a specified time
period. Collar transactions involve an agreement between two parties in which
the first party makes payments to the counterparty when a designated market
interest rate goes above a designated level of predetermined dates or during a
specified time period, and the counterparty makes payments to the first party
when a designated market interest rate goes below a designated level on
predetermined dates or during a specified time period.
 
BOOK-ENTRY REGISTRATION OF SECURITIES
 
     As described in the related Prospectus Supplement, if not issued in fully
registered form, each class of Securities will be registered as book-entry
certificates (the 'Book-Entry Securities'). Persons acquiring beneficial
ownership interests in the Securities ('Security Owners') will hold their
Securities through the Depository Trust Company ('DTC') in the United States, or
CEDEL or Euroclear (in Europe) if they are participants of such systems, or
indirectly through organizations which are participants in such systems. The
Book-Entry Securities will be issued in one or more certificates which equal the
aggregate principal balance of the Securities and will initially be registered
in the name of Cede & Co., the nominee of DTC. CEDEL and Euroclear will hold
omnibus positions on behalf of their participants through customers' securities
accounts in CEDEL's and Euroclear's names on the books of their respective
depositaries which in turn will hold such positions in customers' securities
accounts in the depositaries' names on the books of DTC. Citibank, N.A., will
act as depositary for CEDEL and The Chase Manhattan Bank will act as depositary
for Euroclear (in such capacities, individually the 'Relevant Depositary' and
collectively the 'European Depositaries'). Except as described below, no person
acquiring a Book-Entry Security (each, a 'beneficial owner') will be entitled to
receive a physical certificate representing such Security (a 'Definitive
Security'). Unless and until Definitive Securities are issued, it is anticipated
that the only 'Securityholders' of the Securities will be Cede & Co., as nominee
of DTC. Security Owners are only permitted to exercise their rights indirectly
through Participants and DTC.
 
     The beneficial owner's ownership of a Book-Entry Security will be recorded
on the records of the brokerage firm, bank, thrift institution or other
financial intermediary (each, a 'Financial Intermediary') that maintains the
beneficial owner's account for such purpose. In turn, the Financial
Intermediary's ownership of such Book-Entry Security will be recorded on the
records of DTC (or of a participating firm that acts as agent for the Financial
Intermediary, whose interest will in turn be recorded on the records of DTC, if
the beneficial owner's Financial Intermediary is not a DTC participant, and on
the records of CEDEL or Euroclear, as appropriate).
 
     Security Owners will receive all distributions of principal of, and
interest on, the Securities from the Trustee through DTC and DTC participants.
While the Securities are outstanding (except under the circumstances described
below), under the rules, regulations and procedures creating and affecting DTC
and its operations (the 'Rules'), DTC is required to make book-entry transfers
among Participants on whose behalf it acts with respect to the Securities and is
required to receive and transmit distributions of principal of, and interest on,
the Securities. Participants and indirect participants with whom Security Owners
have accounts with respect to Securities are similarly required to make
book-entry transfers and receive and transmit such distributions on behalf of
their respective Security Owners. Accordingly, although Security Owners will not
possess certificates, the Rules provide a mechanism by which Security Owners
will receive distributions and will be able to transfer their interest.
 
     Security Owners will not receive or be entitled to receive certificates
representing their respective interests in the Securities, except under the
limited circumstances described below. Unless and until Definitive Securities
are issued, Security Owners who are not Participants may transfer ownership of
Securities only through Participants and indirect participants by instructing
such Participants and indirect participants to transfer Securities, by
book-entry transfer, through DTC for the account of the purchasers of such
Securities, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of Securities will be executed through DTC and the accounts of the
respective Participants at DTC will be debited and credited. Similarly, the
Participants and indirect participants
 
                                       40
 <PAGE>
<PAGE>
will make debits or credits, as the case may be, on their records on behalf of
the selling and purchasing Security Owners.
 
     Because of time zone differences, credits of securities received in CEDEL
or Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
CEDEL Participants on such business day. Cash received in CEDEL or Euroclear as
a result of sales of securities by or through a CEDEL Participant (as defined
herein) or Euroclear Participant (as defined herein) to a DTC Participant will
be received with value on the DTC settlement date but will be available in the
relevant CEDEL or Euroclear cash account only as of the business day following
settlement in DTC.
 
     Transfers between Participants will occur in accordance with DTC rules.
Transfers between CEDEL Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through CEDEL
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. CEDEL Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
     CEDEL is incorporated under the laws of Luxembourg as a professional
depository. CEDEL holds securities for its participating organizations ('CEDEL
Participants') and facilitates the clearance and settlement of securities
transactions between CEDEL Participants through electronic book-entry changes in
accounts of CEDEL Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in CEDEL in any of 28
currencies, including United States dollars. CEDEL provides to its CEDEL
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. CEDEL interfaces with domestic markets in several
countries. As a professional depository, CEDEL is subject to regulation by the
Luxembourg Monetary Institute. CEDEL participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to CEDEL is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a CEDEL Participant, either directly or indirectly.
 
     Euroclear was created in 1968 to hold securities for its participants
('Euroclear Participants') and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York ('Morgan' and in such capacity, the
'Euroclear Operator'), under contract with Euroclear Clearance Systems S.C., a
Belgian cooperative corporation (the 'Belgian Cooperative'). All operations are
conducted by Morgan, and all Euroclear securities clearance accounts and
Euroclear cash accounts are accounts with the Euroclear Operator, not the
Belgian Cooperative. The Belgian Cooperative establishes policy for Euroclear on
behalf of Euroclear Participants. Euroclear Participants include banks
(including central banks), securities brokers and dealers and other professional
financial intermediaries. Indirect access to Euroclear is also available to
other firms that clear through or maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.
 
                                       41

     Morgan is the Belgian branch of a New York banking corporation which is a
member bank of the Federal Reserve System. As such, it is regulated and examined
by the Board of Governors of the Federal Reserve System and the New York State
Banking Department, as well as the Belgian Banking Commission.
 
     Securities clearance accounts and cash accounts with Morgan are governed by
the Terms and Conditions Governing Use of Euroclear and the related Operating
Procedures of the Euroclear System and applicable Belgian law (collectively, the
'Terms and Conditions'). The Terms and Conditions govern transfers of securities
and cash within Euroclear, withdrawals of securities and cash from Euroclear,
and receipts of payments with respect to securities in Euroclear. All securities
in Euroclear are held on a fungible basis without attribution of specific
certificates to specific securities clearance accounts. The Euroclear Operator
acts under the Terms and Conditions only on behalf of Euroclear Participants,
and has no record of or relationship with persons holding through Euroclear
Participants.
 
     Under a book-entry format, beneficial owners of the Book-Entry Securities
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Trustee to Cede & Co., as nominee of DTC. Distributions with
respect to Securities held through CEDEL or Euroclear will be credited to the
cash accounts of CEDEL Participants or Euroclear Participants in accordance with
the relevant system's rules and procedures, to the extent received by the
Relevant Depositary. Such distributions will be subject to tax reporting in
accordance with relevant United States tax laws and regulations. See 'Federal
Income Tax Consequences -- Tax Treatment of Foreign Investors' and ' -- Tax
Consequences to Holders of the Notes -- Backup Withholding' herein. Because DTC
can only act on behalf of Financial Intermediaries, the ability of a beneficial
owner to pledge Book-Entry Securities to persons or entities that do not
participate in the Depository system may be limited due to the lack of physical
certificates for such Book-Entry Securities. In addition, issuance of the Book-
Entry Securities in book-entry form may reduce the liquidity of such Securities
in the secondary market since certain potential investors may be unwilling to
purchase Securities for which they cannot obtain physical certificates.
 
     Monthly and annual reports on the Trust will be provided to Cede & Co., as
nominee of DTC, and may be made available by Cede & Co. to beneficial owners
upon request, in accordance with the rules, regulations and procedures creating
and affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Securities of such beneficial owners are credited.
 
     DTC has advised the Trustee that, unless and until Definitive Securities
are issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Securities under the applicable Agreement only at the direction of
one or more Financial Intermediaries to whose DTC accounts the Book-Entry
Securities are credited, to the extent that such actions are taken on behalf of
Financial Intermediaries whose holdings include such Book-Entry Securities.
CEDEL or the Euroclear Operator, as the case may be, will take any other action
permitted to be taken by a Securityholder under the Agreement on behalf of a
CEDEL Participant or Euroclear Participant only in accordance with its relevant
rules and procedures and subject to the ability of the Relevant Depositary to
effect such actions on its behalf through DTC. DTC may take actions, at the
direction of the related Participants, with respect to some Securities which
conflict with actions taken with respect to other Securities.
 
     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 through DTC of
Definitive Securities. Upon surrender by DTC of the global certificate or
certificates representing the Book-Entry Securities and instructions for
re-registration, the Trustee will issue Definitive Securities, and thereafter
the Trustee will recognize the holders of such Definitive Securities as
Securityholders under the applicable Agreement.
 
     Although DTC, CEDEL and Euroclear have agreed to the foregoing procedures
in order to facilitate transfers of Securities among participants of DTC, CEDEL
and Euroclear, they are under no obligation to perform or continue to perform
such procedures and such procedures may be discontinued at any time.
 
     None of the Master Servicer, the Depositor or the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Book-Entry Securities held by
Cede & Co., as nominee of DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

                               CREDIT ENHANCEMENT
 
GENERAL
 
     Credit enhancement may be provided with respect to one or more classes of a
Series of Securities or with respect to the related Trust Fund Assets. Credit
enhancement may be in the form of a limited financial guaranty policy issued by
an entity named in the related Prospectus Supplement, the subordination of one
or more classes of the Securities of such Series, the establishment of one or
more Reserve Accounts, the use of a cross-collateralization feature, use of a
mortgage pool insurance policy, FHA Insurance, VA Guarantee, bankruptcy bond,
special hazard insurance policy, surety bond, letter of credit, guaranteed
investment contract, overcollateralization, or another method of credit
enhancement contemplated herein and described in the related Prospectus
Supplement, or any combination of the foregoing. Unless otherwise specified in
the related Prospectus Supplement, credit enhancement will not provide
protection against all risks of loss and will not guarantee repayment of the
entire principal balance of the Securities and interest thereon. If losses occur
which exceed the amount covered by credit enhancement or which are not covered
by the credit enhancement, Securityholders will bear their allocable share of
any deficiencies.
 
SUBORDINATION
 
     If so specified in the related Prospectus Supplement, protection afforded
to holders of one or more classes of Securities of a Series by means of the
subordination feature may be accomplished by the preferential right of holders
of one or more other classes of such Series (the 'Senior Securities') to
distributions in respect of scheduled principal, Principal Prepayments, interest
or any combination thereof that otherwise would have been payable to holders of
Subordinated Securities under the circumstances and to the extent specified in
the related Prospectus Supplement. Protection may also be afforded to the
holders of Senior Securities of a Series by: (i) reducing the ownership interest
(if applicable) of the related Subordinated Securities; (ii) a combination of
the immediately preceding sentence and clause (i) above; or (iii) as otherwise
described in the related Prospectus Supplement. If so specified in the related
Prospectus Supplement, delays in receipt of scheduled payments on the Loans and
losses on defaulted Loans may be borne first by the various classes of
Subordinated Securities and thereafter by the various classes of Senior
Securities, in each case under the circumstances and subject to the limitations
specified in such Prospectus Supplement. The aggregate distributions in respect
of delinquent payments on the Loans over the lives of the Securities or at any
time, the aggregate losses in respect of defaulted Loans which must be borne by
the Subordinated Securities by virtue of subordination and the amount of the
distributions otherwise distributable to the Subordinated Securityholders that
will be distributable to Senior Securityholders on any Distribution Date may be
limited as specified in the related Prospectus Supplement. If aggregate
distributions in respect of delinquent payments on the Loans or aggregate losses
in respect of such Loans were to exceed an amount specified in the related
Prospectus Supplement, holders of Senior Securities would experience losses on
the Securities.
 
     In addition to or in lieu of the foregoing, if so specified in the related
Prospectus Supplement, all or any portion of distributions otherwise payable to
holders of Subordinated Securities on any Distribution Date may instead be
deposited into one or more Reserve Accounts established with the Trustee or
distributed to holders of Senior Securities. Such deposits may be made on each
Distribution Date, for specified periods or until the balance in the Reserve
Account has reached a specified amount and, following payments from the Reserve
Account to holders of Senior Securities or otherwise, thereafter to the extent
necessary to restore the balance in the Reserve Account to required levels, in
each case as specified in the related Prospectus Supplement. Amounts on deposit
in the Reserve Account may be released to the holders of certain classes of
Securities at the times and under the circumstances specified in such Prospectus
Supplement.
 
     If specified in the related Prospectus Supplement, various classes of
Senior Securities and Subordinated Securities may themselves be subordinate in
their right to receive certain distributions to other classes of Senior and
Subordinated Securities, respectively, through a cross-collateralization
mechanism or otherwise.
 
     As between classes of Senior Securities and as between classes of
Subordinated Securities, distributions may be allocated among such classes (i)
in the order of their scheduled final distribution dates, (ii) in accordance
with a schedule or formula, (iii) in relation to the occurrence of events or
(iv) otherwise, in each case as specified in the related Prospectus Supplement.
As between classes of Subordinated Securities, payments to holders of Senior
Securities on account of delinquencies or losses and payments to any Reserve
Account will be allocated as specified in the related Prospectus Supplement.
 
                                       43

<PAGE>
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 'The Agreements -- Termination: Optional
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.
 
INSURANCE POLICIES, SURETY BONDS AND GUARANTIES
 
     If so provided in the Prospectus Supplement for a Series of Securities,
deficiencies in amounts otherwise payable on such Securities or certain classes
thereof will be covered by insurance policies and/or surety bonds provided by
one or more insurance companies or sureties. Such instruments may cover, with
respect to one or more classes of Securities of the related series, timely
distributions of interest and/or full distributions of principal on the basis of
a schedule of principal distributions set forth in or determined in the manner
specified in the related Prospectus Supplement. In addition, if specified in the
related Prospectus Supplement, a Trust Fund may also include bankruptcy bonds,
special hazard insurance policies, other insurance or guaranties for the purpose
of (i) maintaining timely payments or providing additional protection against
losses on the assets included in such Trust Fund, (ii) paying administrative
expenses or (iii) establishing a minimum reinvestment rate on the payments made
in respect of such assets or principal payment rate on such assets. Such
arrangements may include agreements under which Securityholders are entitled to
receive amounts deposited in various accounts held by the Trustee upon the terms
specified in such Prospectus Supplement. A copy of any such instrument for a
series 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.
 
OVER-COLLATERALIZATION
 
     If so provided in the Prospectus Supplement for a Series of Securities, a
portion of the interest payment on each Loan may be applied as an additional
distribution in respect of principal to reduce the principal balance of a
certain class or classes of Securities and, thus, accelerate the rate of payment
of principal on such class or classes of Securities.
 
RESERVE ACCOUNTS
 
     If specified in the related Prospectus Supplement, credit support with
respect to a Series of Securities will be provided by the establishment and
maintenance with the Trustee for such Series of Securities, in trust, of one or
more Reserve Accounts for such Series. The related Prospectus Supplement will
specify whether or not any such Reserve Accounts will be included in the Trust
Fund for such Series.
 
     The Reserve Account for a Series will be funded (i) by the deposit therein
of cash, United States Treasury securities, instruments evidencing ownership of
principal or interest payments thereon, letters of credit, demand notes,
certificates of deposit or a combination thereof in the aggregate amount
specified in the related Prospectus Supplement, (ii) by the deposit therein from
time to time of certain amounts, as specified in the related Prospectus
Supplement to which the Subordinate Securityholders, if any, would otherwise be
entitled or (iii) in such other manner as may be specified in the related
Prospectus Supplement.
 
     Any amounts on deposit in the Reserve Account and the proceeds of any other
instrument upon maturity will be held in cash or will be invested in 'Permitted
Investments' which, in general, will include obligations of the United States
and certain agencies thereof, certificates of deposit, certain commercial paper,
time deposits and bankers acceptances sold by eligible commercial banks and
certain repurchase agreements of United States
 
                                       44
 <PAGE>
<PAGE>
government securities with eligible commercial banks. If a letter of credit is
deposited with the Trustee, such letter of credit will be irrevocable. Unless
otherwise specified in the related Prospectus Supplement, any instrument
deposited therein will name the Trustee, in its capacity as trustee for the
holders of the Securities, as beneficiary and will be issued by an entity
acceptable to each Rating Agency that rates the Securities of the related
Series. Additional information with respect to such instruments deposited in the
Reserve Accounts will be set forth in the related Prospectus Supplement.
 
     Any amounts so deposited and payments on instruments so deposited will be
available for withdrawal from the Reserve Account for distribution to the
holders of Securities of the related Series for the purposes, in the manner and
at the times specified in the related Prospectus Supplement.
 
POOL INSURANCE POLICIES
 
     If specified in the related Prospectus Supplement, a separate pool
insurance policy ('Pool Insurance Policy') will be obtained for the Pool and
issued by the insurer (the 'Pool Insurer') named in such Prospectus Supplement.
Each Pool Insurance Policy will, subject to the limitations described therein,
cover loss by reason of default in payment on Loans in the Pool in an amount
equal to a percentage specified in such Prospectus Supplement of the aggregate
principal balance of such Loans on the Cut-off Date which are not covered as to
their entire outstanding principal balances by Primary Mortgage Insurance
Policies. As more fully described in the related Prospectus Supplement, the
Master Servicer will present claims thereunder to the Pool Insurer on behalf of
itself, the Trustee and the holders of the Securities of the related Series. The
Pool Insurance Policies, however, are not blanket policies against loss, since
claims thereunder may only be made respecting particular defaulted Loans and
only upon satisfaction of certain conditions precedent as described in the
related Prospectus Supplement. Unless otherwise specified in the related
Prospectus Supplement, the Pool Insurance Policies will not cover losses due to
a failure to pay or denial of a claim under a Primary Mortgage Insurance Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, the
original amount of coverage under each Pool Insurance Policy will be reduced
over the life of the related Securities by the aggregate dollar amount of claims
paid less the aggregate of the net amounts realized by the Pool Insurer upon
disposition of all foreclosed properties. The amount of claims paid will include
certain expenses incurred by the Master Servicer as well as accrued interest on
delinquent Loans to the date of payment of the claim, unless otherwise specified
in the related Prospectus Supplement. Accordingly, if aggregate net claims paid
under any Pool Insurance Policy reach the original policy limit, coverage under
that Pool Insurance Policy will be exhausted and any further losses will be
borne by the related Securityholders.
 
CROSS-COLLATERALIZATION
 
     If specified in the related Prospectus Supplement, the beneficial ownership
of separate groups of assets included in a Trust Fund may be evidenced by
separate classes of the related Series of Securities. In such case, credit
support may be provided by a cross-collateralization feature which requires that
distributions be made with respect to Securities evidencing a beneficial
ownership interest in, or secured by, one or more asset groups within the same
Trust Fund prior to distributions to Subordinated Securities evidencing a
beneficial ownership interest in, or secured by, one or more other asset groups
within such Trust Fund. Cross-collateralization may be provided by (i) the
allocation of certain excess amounts generated by one or more asset groups to
one or more other asset groups within the same Trust Fund or (ii) the allocation
of losses with respect to one or more asset groups to one or more other asset
groups within the same Trust Fund. Such excess amounts will be applied and/or
such losses will be allocated to the class or classes of Subordinated Securities
of the related Series then outstanding having the lowest rating assigned by any
Rating Agency or the lowest payment priority, in each case to the extent and in
the manner more specifically described in the related Prospectus Supplement. The
Prospectus Supplement for a Series which includes a cross-collateralization
feature will describe the manner and conditions for applying such
cross-collateralization feature.
 
     If specified in the related Prospectus Supplement, the coverage provided by
one or more of the forms of credit enhancement described in this Prospectus may
apply concurrently to two or more separate Trust Funds. If applicable, the
related Prospectus Supplement will identify the Trust Funds to which such credit
enhancement relates and the manner of determining the amount of coverage
provided to such Trust Funds thereby and of the application of such coverage to
the identified Trust Funds.

                      YIELD AND PREPAYMENT CONSIDERATIONS
 
     The yields to maturity and weighted average lives of the Securities will be
affected primarily by the amount and timing of principal payments received on or
in respect of the Trust Fund Assets included in the related Trust Fund. The
original terms to maturity of the Loans in a given Pool will vary depending upon
the type of Loans included therein. Each Prospectus Supplement will contain
information with respect to the type and maturities of the Loans in the related
Pool. The related Prospectus Supplement will specify the circumstances, if any,
under which the related Loans will be subject to prepayment penalties. The
prepayment experience on the Loans in a Pool will affect the weighted average
life of the related Series of Securities.
 
     The rate of prepayment on the Loans cannot be predicted. Home equity loans
and home improvement contracts have been originated in significant volume only
during the past few years and the Depositor is not aware of any publicly
available studies or statistics on the rate of prepayment of such loans.
Generally, home equity loans and home improvement contracts are not viewed by
borrowers as permanent financing. Accordingly, such Loans may experience a
higher rate of prepayment than traditional first mortgage loans. On the other
hand, because home equity loans such as the Revolving Credit Line Loans
generally are not fully amortizing, the absence of voluntary borrower
prepayments could cause rates of principal payments lower than, or similar to,
those of traditional fully-amortizing first mortgage loans. The prepayment
experience of the related Trust Fund may be affected by a wide variety of
factors, including general economic conditions, prevailing interest rate levels,
the availability of alternative financing, homeowner mobility and the frequency
and amount of any future draws on any Revolving Credit Line Loans. Other factors
that might be expected to affect the prepayment rate of a pool of home equity
mortgage loans or home improvement contracts include the amounts of, and
interest rates on, the underlying senior mortgage loans, and the use of first
mortgage loans as long-term financing for home purchase and subordinate mortgage
loans as shorter-term financing for a variety of purposes, including home
improvement, education expenses and purchases of consumer durables such as
automobiles. Accordingly, such Loans may experience a higher rate of prepayment
than traditional fixed-rate mortgage loans. In addition, any future limitations
on the right of borrowers to deduct interest payments on home equity loans for
federal income tax purposes may further increase the rate of prepayments of the
Loans. The enforcement of a 'due-on-sale' provision (as described below) will
have the same effect as a prepayment of the related Loan. See 'Certain Legal
Aspects of the Loans -- Due-on-Sale Clauses'. The yield to an investor who
purchases Securities in the secondary market at a price other than par will vary
from the anticipated yield if the rate of prepayment on the Loans is actually
different than the rate anticipated by such investor at the time such Securities
were purchased.
 
     Collections on Revolving Credit Line Loans may vary because, among other
things, borrowers may (i) make payments during any month as low as the minimum
monthly payment for such month or, during the interest-only period for certain
Revolving Credit Line Loans and, in more limited circumstances, Closed-End
Loans, with respect to which an interest-only payment option has been selected,
the interest and the fees and charges for such month or (ii) make payments as
high as the entire outstanding principal balance plus accrued interest and the
fees and charges thereon. It is possible that borrowers may fail to make the
required periodic payments. In addition, collections on the Loans may vary due
to seasonal purchasing and the payment habits of borrowers.
 
     Unless otherwise specified in the related Prospectus Supplement,
substantially all conventional Loans will contain due-on-sale provisions
permitting the mortgagee to accelerate the maturity of the loan upon sale or
certain transfers by the borrower of the related Property. Loans insured by the
FHA, and Single Family Loans partially guaranteed by the VA, are assumable with
the consent of the FHA and the VA, respectively. Thus, the rate of prepayments
on such Loans may be lower than that of conventional Loans bearing comparable
interest rates. The Master Servicer generally will enforce any due-on-sale or
due-on-encumbrance clause, to the extent it has knowledge of the conveyance or
further encumbrance or the proposed conveyance or proposed further encumbrance
of the Property and reasonably believes that it is entitled to do so under
applicable law; provided, however, that the Master Servicer will not take any
enforcement action that would impair or threaten to impair any recovery under
any related insurance policy. See 'The Agreements -- Collection Procedures' and
'Certain Legal Aspects of the Loans' for a description of certain provisions of
each Agreement and certain legal developments that may affect the prepayment
experience on the Loans.
 
     The rate of prepayments with respect to conventional mortgage loans has
fluctuated significantly in recent years. In general, if prevailing rates fall
significantly below the Loan Rates borne by the Loans, such Loans are
 
                                       46
 <PAGE>
<PAGE>
more likely to be subject to higher prepayment rates than if prevailing interest
rates remain at or above such Loan Rates. Conversely, if prevailing interest
rates rise appreciably above the Loan Rates borne by the Loans, such Loans are
more likely to experience a lower prepayment rate than if prevailing rates
remain at or below such Loan Rates. However, there can be no assurance that such
will be the case.
 
     When a full prepayment is made on a Loan, the borrower is charged interest
on the principal amount of the Loan so prepaid only for the number of days in
the month actually elapsed up to the date of the prepayment, rather than for a
full month. The effect of prepayments in full will be to reduce the amount of
interest passed through or paid in the following month to holders of Securities
because interest on the principal amount of any Loan so prepaid will generally
be paid only to the date of prepayment. Partial prepayments in a given month may
be applied to the outstanding principal balances of the Loans so prepaid on the
first day of the month of receipt or the month following receipt. In the latter
case, partial prepayments will not reduce the amount of interest passed through
or paid in such month. Unless otherwise specified in the related Prospectus
Supplement, neither full nor partial prepayments will be passed through or paid
until the month following receipt.
 
     Even assuming that the Properties provide adequate security for the Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Loans and corresponding delays in the receipt of related proceeds by
Securityholders could occur. An action to foreclose on a Property securing a
Loan is regulated by state statutes and rules and is subject to many of the
delays and expenses of other lawsuits if defenses or counterclaims are
interposed, sometimes requiring several years to complete. Furthermore, in some
states an action to obtain a deficiency judgment is not permitted following a
nonjudicial sale of a property. In the event of a default by a borrower, these
restrictions among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Property or to obtain liquidation proceeds
sufficient to repay all amounts due on the related Loan. In addition, the Master
Servicer will be entitled to deduct from related liquidation proceeds all
expenses reasonably incurred in attempting to recover amounts due on defaulted
Loans and not yet repaid, including payments to senior lienholders, legal fees
and costs of legal action, real estate taxes and maintenance and preservation
expenses.
 
     Liquidation expenses with respect to defaulted mortgage loans generally do
not vary directly with the outstanding principal balance of the loan at the time
of default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a large remaining
principal balance, the amount realized after expenses of liquidation would be
smaller as a percentage of the remaining principal balance of the small mortgage
loan than would be the case with the other defaulted mortgage loan having a
large remaining principal balance.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of certain originators and
servicers of Loans. In addition, most have other laws, public policy and general
principles of equity relating to the protection of consumers, unfair and
deceptive acts and practices which may apply to the origination, servicing and
collection of the Loans. Depending on the provisions of the applicable law and
the specific facts and circumstances involved, violations of these laws,
policies and principles may limit the ability of the Master Servicer to collect
all or part of the principal of or interest on the Loans, may entitle the
borrower to a refund of amounts previously paid and, in addition, could subject
the Master Servicer to damages and administrative sanctions.
 
     If the rate at which interest is passed through or paid to the holders of
Securities of a Series is calculated on a Loan-by-Loan basis, disproportionate
principal prepayments among Loans with different Loan Rates will affect the
yield on such Securities. In most cases, the effective yield to Securityholders
will be lower than the yield otherwise produced by the applicable pass-through
rate or interest rate and purchase price, because while interest will accrue on
each Loan from the first day of the month (unless otherwise specified in the
related Prospectus Supplement), the distribution of such interest will not be
made earlier than the month following the month of accrual.
 
     Under certain circumstances, the Master Servicer, the holders of the
residual interests in a REMIC or any person specified in the related Prospectus
Supplement may have the option to purchase the assets of a Trust Fund thereby
effecting earlier retirement of the related Series of Securities. See 'The
Agreements -- Termination; Optional Termination'.

     The relative contribution of the various factors affecting prepayment may
vary from time to time. There can be no assurance as to the rate of payment of
principal of the Trust Fund Assets at any time or over the lives of the
Securities.
 
     The Prospectus Supplement relating to a Series of Securities will discuss
in greater detail the effect of the rate and timing of principal payments
(including prepayments), delinquencies and losses on the yield, weighted average
lives and maturities of such Securities.
 
                                 THE AGREEMENTS
 
     Set forth below is a description of the material provisions of each
Agreement which are not described elsewhere in this Prospectus. The description
is subject to, and qualified by reference to, the provisions of each Agreement.
Where particular provisions or terms used in the Agreements are referred to,
such provisions or terms are as specified in the Agreements.
 
ASSIGNMENT OF THE TRUST FUND ASSETS
 
     Assignment of the Loans. At the time of issuance of the Securities of a
Series, the Depositor will cause the Loans comprising the related Trust Fund to
be assigned to the Trustee, without recourse, together with all principal and
interest received (if the Contracts are sold based on actual principal balances)
or scheduled to be received (if the Contracts are sold based on scheduled
principal balances) by or on behalf of the Depositor on or with respect to such
Loans after the Cut-off Date and other than any Retained Interest specified in
the related Prospectus Supplement. The Trustee will, concurrently with such
assignment, deliver such Securities to the Depositor in exchange for the Loans.
Each Loan will be identified in a schedule appearing as an exhibit to the
related Agreement. Such schedule will include information as to the outstanding
principal balance of each Loan after application of payments due on or before
the Cut-off Date, as well as information regarding the Loan Rate or APR, the
maturity of the Loan, the Loan-to-Value Ratios or Combined Loan-to-Value Ratios,
as applicable, at origination and certain other information.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Agreement will require that, on or prior to the Closing Date, the Depositor will
also deliver or cause to be delivered to the Trustee (or to the custodian
hereinafter referred to) as to each Single Family Loan or Multifamily Loan,
among other things, (i) the mortgage note or contract endorsed without recourse
in blank or to the order of the Trustee, (ii) the mortgage, deed of trust or
similar instrument (a 'Mortgage') with evidence of recording indicated thereon
(except for any Mortgage not returned from the public recording office, in which
case the Depositor will deliver or cause to be delivered a copy of such Mortgage
together with a certificate that the original of such Mortgage was delivered to
such recording office), (iii) an assignment of the Mortgage to the Trustee,
which assignment will be in recordable form in the case of a Mortgage assignment
and (iv) such other security documents, including those relating to any senior
interests in the Property, as may be specified in the related Prospectus
Supplement or the related Agreement. Unless otherwise specified in the related
Prospectus Supplement, the Depositor will promptly cause the assignments of the
related Loans to be recorded in the appropriate public office for real property
records, except in states in which the Seller has reasonably determined (in
certain circumstances, as evidenced by an opinion of counsel acceptable to the
Trustee) that such recording is not required to protect the Trustee's interest
in such Loans against the claim of any subsequent transferee or any successor to
or creditor of the Depositor or the originator of such Loans.
 
     With respect to any Loans that are Cooperative Loans, the Depositor will
cause to be delivered to the Trustee the related original cooperative note
endorsed without recourse in blank or 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, related blank stock powers and any other document specified in the
related Prospectus Supplement. The Depositor will cause to be filed in the
appropriate office an assignment and a financing statement evidencing the
Trustee's security interest in each Cooperative Loan.
 
     With respect to any Loans that are Home Equity Loans, the related
Prospectus Supplement will specify whether the documents relating to such Loans
will be required to be delivered to the Trustee (or a custodian) and whether
assignments of the related Mortgage to the Trustee will be recorded. In the
event documents are not required to be delivered, they will be retained by the
Master Servicer, which may also be the Seller.
 
                                       48
 <PAGE>
<PAGE>
     With respect to the Home Improvement Contracts, the related Prospectus
Supplement will specify whether the documents relating to such Contracts will be
required to be delivered to the Trustee (or a custodian). Notwithstanding the
foregoing, unless otherwise specified in the related Prospectus Supplement, the
Depositor will not deliver to the Trustee the original Mortgage securing a Home
Improvement Contract. In order to give notice of the right, title and interest
of Securityholders to the Home Improvement Contracts, the Depositor will cause a
UCC-1 financing statement to be executed by the Depositor or the Seller
identifying the Trustee as the secured party and identifying all Home
Improvement Contracts as collateral. Unless otherwise specified in the related
Prospectus Supplement, the Home Improvement Contracts will not be stamped or
otherwise marked to reflect their assignment to the Trustee. Therefore, if,
through negligence, fraud or otherwise, a subsequent purchaser were able to take
physical possession of the Home Improvement Contracts without notice of such
assignment, the interest of Securityholders in the Home Improvement Contracts
could be defeated. See 'Certain Legal Aspects of the Loans -- The Home
Improvement Contracts'.
 
     The Trustee (or the custodian) will review the loan documents that have
been delivered to it within the time period specified in the related Prospectus
Supplement after receipt thereof, and the Trustee (or the custodian) will hold
such documents in trust for the benefit of the related Securityholders. Unless
otherwise specified in the related Prospectus Supplement, if any such document
is found to be missing or defective in any material respect, the Trustee (or
such custodian) will notify the Master Servicer and the Depositor, and the
Master Servicer will notify the related Seller. If such Seller cannot cure the
omission or defect within the time period specified in the related Prospectus
Supplement after receipt of such notice, such Seller will be obligated to either
(i) purchase the related Loan from the Trust Fund at the Purchase Price or (ii)
if so specified in the related Prospectus Supplement, remove such Loan from the
Trust Fund and substitute in its place one or more other Loans that meets
certain requirements set forth therein. There can be no assurance that a Seller
will fulfill this purchase or substitution obligation. Although the Master
Servicer may be obligated to enforce such obligation to the extent described
above under 'Loan Program -- Representations by Sellers; Repurchases,' the
Master Servicer will not be obligated to purchase or replace such Loan if the
Seller defaults on its obligation (nor will the Master Servicer otherwise be
obligated to purchase or replace any such Loan for any other reason). Unless
otherwise specified in the related Prospectus Supplement, this obligation of the
Seller to cure, purchase or substitute constitutes the sole remedy available to
the Securityholders or the Trustee for omission of, or a material defect in, a
constituent document.
 
     Notwithstanding the foregoing provisions, with respect to a Trust Fund for
which a REMIC election is to be made, no purchase or substitution of a Loan will
be made if such purchase or substitution would result in a prohibited
transaction tax under the Code (unless the Master Servicer or a holder of the
related residual certificate otherwise pays such prohibited transaction from its
own funds as described herein). See 'Loan Program -- Representations by Sellers;
Repurchases'.
 
     The Trustee will be authorized to appoint a custodian pursuant to a
custodial agreement to maintain possession of and, if applicable, to review the
documents relating to the Loans as agent of the Trustee.
 
NO RECOURSE TO SELLERS, DEPOSITOR OR MASTER SERVICER
 
     As described above under ' -- Assignment of the Loans,' the Depositor will
cause the Loans comprising the related Trust Fund to be assigned to the Trustee,
without recourse. However, each Seller will be obligated to repurchase or
substitute for any Loan as to which certain representations and warranties are
breached where such breach materially and adversely affects the interests of the
Securityholders, or for failure to deliver certain documents relating to the
Loans as described herein under 'Assignment of the Loans' and 'Loan
Program -- Representations by Sellers; Repurchases'. These obligations to
purchase or substitute constitute the sole remedy available to the
Securityholders or the Trustee for a breach of any such representation or
failure to deliver a constituent document.
 
PAYMENTS ON LOANS; DEPOSITS TO SECURITY ACCOUNT
 
     The Master Servicer will establish and maintain or cause to be established
and maintained with respect to the related Trust Fund a separate account or
accounts for the collection of payments on the related Trust Fund Assets in the
Trust Fund (the 'Security Account') which, unless otherwise specified in the
related Prospectus Supplement, must be either (i) maintained with a depository
institution the debt obligations of which (or in the
 
                                       49
 <PAGE>
<PAGE>
case of a depository institution that is the principal subsidiary of a holding
company, the obligations of which) are rated in one of the two highest rating
categories by the Rating Agency or Rating Agencies that rated one or more
classes of the related Series of Securities, (ii) an account or accounts the
deposits in which are fully insured by either the Bank Insurance Fund (the
'BIF') of the FDIC or the Savings Association Insurance Fund (as successor to
the Federal Savings and Loan Insurance Corporation ('SAIF')), (iii) an account
or accounts the deposits in which are insured by the BIF or SAIF (to the limits
established by the FDIC), and the uninsured deposits in which are otherwise
secured such that, as evidenced by an opinion of counsel, the Securityholders
have a claim with respect to the funds in the Security Account or a perfected
first priority security interest against any collateral securing such funds that
is superior to the claims of any other depositors or general creditors of the
depository institution with which the Security Account is maintained or (iv) an
account or accounts otherwise acceptable to each Rating Agency. The collateral
eligible to secure amounts in the Security Account is limited to Permitted
Investments. A Security Account may be maintained as an interest bearing account
or the funds held therein may be invested pending each succeeding Distribution
Date in Permitted Investments. Unless otherwise specified in the related
Prospectus Supplement, the Master Servicer or its designee will be entitled to
receive any such interest or other income earned on funds in the Security
Account as additional compensation and will be obligated to deposit in the
Security Account the amount of any loss immediately as realized. The Security
Account may be maintained with the Master Servicer or with a depository
institution that is an affiliate of the Master Servicer, provided it meets the
standards set forth above.
 
     The Master Servicer will deposit or cause to be deposited in the Security
Account for each Trust Fund, to the extent applicable and unless otherwise
specified in the related Prospectus Supplement and provided in the Agreement,
the following payments and collections received or advances made by or on behalf
of it subsequent to the Cut-off Date (other than payments due on or before the
Cut-off Date and exclusive of any amounts representing Retained Interest):
 
          (i) all payments on account of principal, including Principal
     Prepayments and, if specified in the related Prospectus Supplement, any
     applicable prepayment penalties, on the Loans;
 
          (ii) all payments on account of interest on the Loans, net of
     applicable servicing compensation;
 
          (iii) all proceeds (net of unreimbursed payments of property taxes,
     insurance premiums and similar items ('Insured Expenses') incurred, and
     unreimbursed Advances made, by the Master Servicer, if any) of the hazard
     insurance policies and any Primary Mortgage Insurance Policies, to the
     extent such proceeds are not applied to the restoration of the property or
     released to the Mortgagor in accordance with the Master Servicer's normal
     servicing procedures (collectively, 'Insurance Proceeds') and all other
     cash amounts (net of unreimbursed expenses incurred in connection with
     liquidation or foreclosure ('Liquidation Expenses') and unreimbursed
     Advances made, by the Master Servicer, if any) received and retained in
     connection with the liquidation of defaulted Loans, by foreclosure or
     otherwise ('Liquidation Proceeds'), together with any net proceeds received
     on a monthly basis with respect to any properties acquired on behalf of the
     Securityholders by foreclosure or deed in lieu of foreclosure;
 
          (iv) all proceeds of any Loan or property in respect thereof purchased
     by the Master Servicer, the Depositor or any Seller as described under
     'Loan Program -- Representations by Sellers; Repurchases' or
     ' -- Assignment of Trust Fund Assets' above and all proceeds of any Loan
     repurchased as described under ' -- Termination; Optional Termination'
     below;
 
          (v) all payments required to be deposited in the Security Account with
     respect to any deductible clause in any blanket insurance policy described
     under ' -- Hazard Insurance' below;
 
          (vi) any amount required to be deposited by the Master Servicer in
     connection with losses realized on investments for the benefit of the
     Master Servicer of funds held in the Security Account and, to the extent
     specified in the related Prospectus Supplement, any payments required to be
     made by the Master Servicer in connection with prepayment interest
     shortfalls; and
 
          (vii) all other amounts required to be deposited in the Security
     Account pursuant to the Agreement.
 
     The Master Servicer (or the Depositor, as applicable) may from time to time
direct the institution that maintains the Security Account to withdraw funds
from the Security Account for the following purposes:
 
                                       50
 <PAGE>
<PAGE>
          (i) to pay to the Master Servicer the servicing fees described in the
     related Prospectus Supplement, the master servicing fees (subject to
     reduction) and, as additional servicing compensation, earnings on or
     investment income with respect to funds in the amounts in the Security
     Account credited thereto;
 
          (ii) to reimburse the Master Servicer for Advances, such right of
     reimbursement with respect to any Loan being limited to amounts received
     that represent late recoveries of payments of principal and/or interest on
     such Loan (or Insurance Proceeds or Liquidation Proceeds with respect
     thereto) with respect to which such Advance was made;
 
          (iii) to reimburse the Master Servicer for any Advances previously
     made which the Master Servicer has determined to be nonrecoverable;
 
          (iv) to reimburse the Master Servicer from Insurance Proceeds for
     expenses incurred by the Master Servicer and covered by the related
     insurance policies;
 
          (v) to reimburse the Master Servicer for unpaid master servicing fees
     and unreimbursed out-of-pocket costs and expenses incurred by the Master
     Servicer in the performance of its servicing obligations, such right of
     reimbursement being limited to amounts received representing late
     recoveries of the payments for which such advances were made;
 
          (vi) to reimburse the Master Servicer or the Depositor for expenses
     incurred and reimbursable pursuant to the Agreement;
 
          (vii) to withdraw any amount deposited in the Security Account and not
     required to be deposited therein; and
 
          (viii) to clear and terminate the Security Account upon termination of
     the Agreement.
 
     In addition, unless otherwise specified in the related Prospectus
Supplement, on or prior to the business day immediately preceding each
Distribution Date, the Master Servicer shall withdraw from the Security Account
the amount of Available Funds, to the extent on deposit, for deposit in an
account maintained by the Trustee for the related Series of Securities.
 
PRE-FUNDING ACCOUNT
 
     If so provided in the related Prospectus Supplement, the Master Servicer
will establish and maintain a Pre-Funding Account, in the name of the related
Trustee on behalf of the related Securityholders, into which the Depositor will
deposit cash in an amount equal to the Pre-Funded Amount on the related Closing
Date. The Pre-Funding Account will be maintained with the Trustee for the
related Series of Securities and is designed solely to hold funds to be applied
by such Trustee during the Funding Period to pay to the Depositor the purchase
price for Subsequent Loans. Monies on deposit in the Pre-Funding Account will
not be available to cover losses on or in respect of the related Loans. The
Pre-Funded Amount will not exceed 50% of the initial aggregate principal amount
of the Certificates and Notes of the related Series. The Pre-Funded Amount will
be used by the related Trustee to purchase Subsequent Loans from the Depositor
from time to time during the Funding Period. The Funding Period, if any, for a
Trust Fund will begin on the related Closing Date and will end on the date
specified in the related Prospectus Supplement, which in no event will be later
than the date that is one year after the related Closing Date. Monies on deposit
in the Pre-Funding Account may be invested in Permitted Investments under the
circumstances and in the manner described in the related Agreement. Earnings on
investment of funds in the Pre-Funding Account will be deposited into the
related Security Account or such other trust account as is specified in the
related Prospectus Supplement and losses will be charged against the funds on
deposit in the Pre-Funding Account. Any amounts remaining in the Pre-Funding
Account at the end of the Funding Period will be distributed to the related
Securityholders in the manner and priority specified in the related Prospectus
Supplement, as a prepayment of principal of the related Securities.
 
     In addition, if so provided in the related Prospectus Supplement, on the
related Closing Date the Depositor will deposit in an account (the 'Capitalized
Interest Account') cash in such amount as is necessary to cover shortfalls in
interest on the related Series of Securities that may arise as a result of
utilization of the Pre-Funding Account as described above. The Capitalized
Interest Account shall be maintained with the Trustee for the related Series of
Securities and is designed solely to cover the above-mentioned interest
shortfalls. Monies on deposit in the Capitalized Interest Account will not be
available to cover losses on or in respect of the related Loans. To the extent
that the entire amount on deposit in the Capitalized Interest Account has not
been applied
 
                                       51
 <PAGE>
<PAGE>
to cover shortfalls in interest on the related Series of Securities by the end
of the Funding Period, any amounts remaining in the Capitalized Interest Account
will be paid to the Depositor.
 
SUB-SERVICING BY SELLERS
 
     Each Seller of a Loan or any other servicing entity may act as the
Sub-Servicer for such Loan pursuant to an agreement (each, a 'Sub-Servicing
Agreement'), which will not contain any terms inconsistent with the related
Agreement. While each Sub-Servicing Agreement will be a contract solely between
the Master Servicer and the Sub-Servicer, the Agreement pursuant to which a
Series of Securities is issued will provide that, if for any reason the Master
Servicer for such Series of Securities is no longer the Master Servicer of the
related Loans, the Trustee or any successor Master Servicer must recognize the
Sub-Servicer's rights and obligations under such Sub-Servicing Agreement.
 
     All references in this Prospectus and in the Prospectus Supplement for any
Series to actions, rights or duties of the Master Servicer will be deemed to
include any one or more Sub-Servicers acting on the Master Servicer's behalf.
Notwithstanding the foregoing, unless otherwise provided in the related
Prospectus Supplement, the Master Servicer will remain liable for its servicing
duties and obligations under the Master Servicing Agreement as if the Master
Servicer alone were servicing the Loans.
 
COLLECTION PROCEDURES
 
     The Master Servicer will make reasonable efforts to collect all payments
called for under the Loans and will, consistent with each Agreement and any Pool
Insurance Policy, Primary Mortgage Insurance Policy, FHA Insurance, VA Guaranty,
bankruptcy bond or alternative arrangements, follow such collection procedures
as are customary with respect to loans that are comparable to the Loans.
Consistent with the above, the Master Servicer may, in its discretion, (i) waive
any assumption fee, late payment or other charge in connection with a Loan and
(ii) to the extent not inconsistent with the coverage of such Loan by a Pool
Insurance Policy, Primary Mortgage Insurance Policy, FHA Insurance, VA Guaranty,
bankruptcy bond or alternative arrangements, if applicable, arrange with a
borrower a schedule for the liquidation of delinquencies running for no more
than 125 days after the applicable due date for each payment. To the extent the
Master Servicer is obligated to make or cause to be made Advances, such
obligation will remain during any period of such an arrangement.
 
     In any case in which property securing a Loan has been, or is about to be,
conveyed by the mortgagor or obligor, the Master Servicer will, to the extent it
has knowledge of such conveyance or proposed conveyance, exercise or cause to be
exercised its rights to accelerate the maturity of such Loan under any
due-on-sale clause applicable thereto, but only if the exercise of such rights
is permitted by applicable law and will not impair or threaten to impair any
recovery under any Primary Mortgage Insurance Policy. If these conditions are
not met or if the Master Servicer reasonably believes it is unable under
applicable law to enforce such due-on-sale clause or if such Loan is a mortgage
loan insured by the FHA or partially guaranteed by the VA, the Master Servicer
will enter into or cause to be entered into an assumption and modification
agreement with the person to whom such property has been or is about to be
conveyed, pursuant to which such person becomes liable for repayment of the Loan
and, to the extent permitted by applicable law, the mortgagor remains liable
thereon. Any fee collected by or on behalf of the Master Servicer for entering
into an assumption agreement will be retained by or on behalf of the Master
Servicer as additional servicing compensation. See 'Certain Legal Aspects of the
Loans -- Due-on-Sale Clauses'. In connection with any such assumption, the terms
of the related Loan may not be changed.
 
     With respect to Cooperative Loans, 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 related
proprietary lease or occupancy agreement. See 'Certain Legal Aspects of the
Loans'. 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.
 
     In general a 'tenant-stockholder' (as defined in Code Section 216(b)(2) of
a corporation that qualifies as a 'cooperative housing corporation' within the
meaning of Code Section 216(b)(1) is allowed a deduction for amounts paid or
accrued within his taxable year to the corporation representing his
proportionate share of
 
                                       52
 <PAGE>
<PAGE>
certain interest expenses and certain real estate taxes allowable as a deduction
under Code Section 216(a) to the corporation under Code Sections 163 and 164. In
order for a corporation to qualify under Code Section 216(b)(1) 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 (as defined in Code
Section 216(b)(2)). By virtue of this requirement, the status of a corporation
for purposes of Code Section 216(b)(1) 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 Code Section 216(a) with respect to those years. In
view of the significance of the tax benefits accorded tenant-stockholders of a
corporation that qualifies under Code Section 216(b)(1), the likelihood that
such a failure would be permitted to continue over a period of years appears
remote.
 
HAZARD INSURANCE
 
     Except as otherwise specified in the related Prospectus Supplement, the
Master Servicer will require the mortgagor or obligor on each Loan to maintain a
hazard insurance policy providing for no less than the coverage of the standard
form of fire insurance policy with extended coverage customary for the type of
Property in the state in which such Property is located. Such coverage will be
in an amount that is at least equal to the lesser of (i) the maximum insurable
value of the improvements securing such Loan or (ii) the greater of (y) the
outstanding principal balance of the Loan and (z) an amount such that the
proceeds of such policy shall be sufficient to prevent the mortgagor and/or the
mortgagee from becoming a co-insurer. All amounts collected by the Master
Servicer under any hazard policy (except for amounts to be applied to the
restoration or repair of the Property or released to the mortgagor or obligor in
accordance with the Master Servicer's normal servicing procedures) will be
deposited in the related Security Account. In the event that the Master Servicer
maintains a blanket policy insuring against hazard losses on all the Loans
comprising part of a Trust Fund, it will conclusively be deemed to have
satisfied its obligation relating to the maintenance of hazard insurance. Such
blanket policy may contain a deductible clause, in which case the Master
Servicer will be required to deposit from its own funds into the related
Security Account the amounts which would have been deposited therein but for
such clause.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements securing a Loan by fire,
lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. Although the policies relating to the Loans may have been underwritten
by different insurers under different state laws in accordance with different
applicable forms and therefore may not contain identical terms and conditions,
the basic terms thereof are dictated by respective state laws, and most 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 mud flows),
nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic animals,
theft and, in certain cases, vandalism and hurricanes. The foregoing list is
merely indicative of certain kinds of uninsured risks and is not intended to be
all inclusive. If the Property securing a Loan is located in a federally
designated special flood area at the time of origination, the Master Servicer
will require the mortgagor or obligor to obtain and maintain flood insurance.
 
     The hazard insurance policies covering properties securing the Loans
typically contain a clause which in effect requires the insured at all time to
carry insurance of a specified percentage (generally 80% to 90%) of the full
replacement value of the insured property in order to recover the full amount of
any partial loss. If the insured's coverage falls below this specified
percentage, then the insurer's liability in the event of partial loss will not
exceed the larger of (i) the actual cash value (generally defined as replacement
cost at the time and place of loss, less physical depreciation) of the
improvements damaged or destroyed or (ii) such proportion of the loss as the
amount of insurance carried bears to the specified percentage of the full
replacement cost of such improvements. Since the amount of hazard insurance the
Master Servicer may cause to be maintained on the improvements securing the
Loans declines as the principal balances owing thereon decrease, and since
improved real estate generally has appreciated in value over time in the past,
the effect of this requirement in the event of partial loss may be that hazard
insurance proceeds will be insufficient to restore fully the damaged property.
If
 
                                       53
 <PAGE>
<PAGE>
specified in the related Prospectus Supplement, a special hazard insurance
policy will be obtained to insure against certain of the uninsured risks
described above. See 'Credit Enhancement'.
 
     The Master Servicer 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.
 
     If the Property securing a defaulted Loan is damaged and proceeds, if any,
from the related hazard insurance policy are insufficient to restore the damaged
Property, the Master Servicer is not required to expend its own funds to restore
the damaged Property unless it determines (i) that such restoration will
increase the proceeds to Securityholders on liquidation of the Loan after
reimbursement of the Master Servicer for its expenses and (ii) that such
expenses will be recoverable by it from related Insurance Proceeds or
Liquidation Proceeds.
 
     If recovery on a defaulted Loan under any related Insurance Policy is not
available for the reasons set forth in the preceding paragraph, or if the
defaulted Loan is not covered by an Insurance Policy, the Master Servicer will
be obligated to follow or cause to be followed such normal practices and
procedures as it deems necessary or advisable to realize upon the defaulted
Loan. If the proceeds of any liquidation of the Property securing the defaulted
Loan are less than the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Trust Fund will realize a loss
in the amount of such difference plus the aggregate of expenses incurred by the
Master Servicer in connection with such proceedings and which are reimbursable
under the Agreement. In the unlikely event that any such proceedings result in a
total recovery which is, after reimbursement to the Master Servicer of its
expenses, in excess of the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Master Servicer will be entitled
to withdraw or retain from the Security Account amounts representing its normal
servicing compensation with respect to such Loan and, unless otherwise specified
in the related Prospectus Supplement, amounts representing the balance of such
excess, exclusive of any amount required by law to be forwarded to the related
borrower, as additional servicing compensation.
 
     If the Master Servicer or its designee recovers Insurance Proceeds which,
when added to any related Liquidation Proceeds and after deduction of certain
expenses reimbursable to the Master Servicer, exceed the principal balance of
such Loan plus interest accrued thereon that is payable to Securityholders, the
Master Servicer will be entitled to withdraw or retain from the Security Account
amounts representing its normal servicing compensation with respect to such
Loan. In the event that the Master Servicer has expended its own funds to
restore the damaged Property and such funds have not been reimbursed under the
related hazard insurance policy, it will be entitled to withdraw from the
Security Account out of related Liquidation Proceeds or Insurance Proceeds an
amount equal to such expenses incurred by it, in which event the Trust Fund may
realize a loss up to the amount so charged. Since Insurance Proceeds cannot
exceed deficiency claims and certain expenses incurred by the Master Servicer,
no such payment or recovery will result in a recovery to the Trust Fund which
exceeds the principal balance of the defaulted Loan together with accrued
interest thereon. See 'Credit Enhancement'.
 
     The proceeds from any liquidation of a Loan will be applied in the
following order of priority: first, to reimburse the Master Servicer for any
unreimbursed expenses incurred by it to restore the related Property and any
unreimbursed servicing compensation payable to the Master Servicer with respect
to such Loan; second, to reimburse the Master Servicer for any unreimbursed
Advances with respect to such Loan; third, to accrued and unpaid interest (to
the extent no Advance has been made for such amount) on such Loan; and fourth,
as a recovery of principal of such Loan.
 
REALIZATION UPON DEFAULTED LOANS
 
     Primary Mortgage Insurance Policies. If so specified in the related
Prospectus Supplement, the Master Servicer will maintain or cause to be
maintained, as the case may be, in full force and effect, a Primary
 
                                       54
 <PAGE>
<PAGE>
Mortgage Insurance Policy with regard to each Loan for which such coverage is
required. Primary Mortgage Insurance Policies reimburse certain losses sustained
by reason of defaults in payments by borrowers. The Master Servicer will not
cancel or refuse to renew any such Primary Mortgage Insurance Policy in effect
at the time of the initial issuance of a Series of Securities that is required
to be kept in force under the applicable Agreement unless the replacement
Primary Mortgage Insurance Policy for such cancelled or nonrenewed policy is
maintained with an insurer whose claims-paying ability is sufficient to maintain
the current rating of the classes of Securities of such Series that have been
rated.
 
     FHA Insurance; VA Guaranties. Loans designated in the related Prospectus
Supplement as insured by the FHA will be insured by the FHA as authorized under
the United States Housing Act of 1937, as amended. In addition to the Title I
Program of the FHA, see 'Certain Legal Aspects of the Loans -- Title I Program,'
certain Loans will be insured under various FHA programs including the standard
FHA 203(b) program to finance the acquisition of one- to four-family housing
units and the FHA 245 graduated payment mortgage program. These programs
generally limit the principal amount and interest rates of the mortgage loans
insured. Loans insured by FHA generally require a minimum down payment of
approximately 5% of the original principal amount of the loan. No FHA-insured
Loans relating to a Series may have an interest rate or original principal
amount exceeding the applicable FHA limits at the time of origination of such
loan.
 
     Loans designated in the related Prospectus Supplement as guaranteed by the
VA will be partially guaranteed by the VA under the Serviceman's Readjustment
Act of 1944, as amended (a 'VA Guaranty'). The Serviceman's Readjustment Act of
1944, as amended, permits a veteran (or in certain instances the spouse of a
veteran) to obtain a mortgage loan guaranty by the VA covering mortgage
financing of the purchase of a one- to four-family dwelling unit at interest
rates permitted by the VA. The program has no mortgage loan limits, requires no
down payment from the purchaser and permits the guaranty of mortgage loans of up
to 30 years' duration. However, no Loan guaranteed by the VA will have an
original principal amount greater than five times the partial VA guaranty for
such Loan. The maximum guaranty that may be issued by the VA under a VA
guaranteed mortgage loan depends upon the original principal amount of the
mortgage loan, as further described in 38 United States Code Section 1803(a), as
amended.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The principal servicing compensation to be paid to the Master Servicer in
respect of its master servicing activities for each Series of Securities will be
equal to the percentage per annum described in the related Prospectus Supplement
(which may vary under certain circumstances) of the outstanding principal
balance of each Loan, and such compensation will be retained by it from
collections of interest on such Loan in the related Trust Fund (the 'Master
Servicing Fee'). As compensation for its servicing duties, a Sub-Servicer or, if
there is no Sub-Servicer, the Master Servicer will be entitled to a monthly
servicing fee as described in the related Prospectus Supplement. In addition,
the Master Servicer or Sub-Servicer will retain all prepayment charges,
assumption fees and late payment charges, to the extent collected from
borrowers, and any benefit that may accrue as a result of the investment of
funds in the applicable Security Account (unless otherwise specified in the
related Prospectus Supplement).
 
     The Master Servicer will, to the extent provided in the related Prospectus
Supplement, pay or cause to be paid certain ongoing expenses associated with
each Trust Fund and incurred by it in connection with its responsibilities under
the related Agreement, including, without limitation, payment of the fees and
disbursements of the Trustee, any custodian appointed by the Trustee, the
certificate registrar and any paying agent, and payment of expenses incurred in
enforcing the obligations of Sub-Servicers and Sellers. The Master Servicer will
be entitled to reimbursement of expenses incurred in enforcing the obligations
of Sub-Servicers and Sellers under certain limited circumstances. Certain other
expenses may be borne by the related Trust Fund as specified in the related
Prospectus Supplement.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Agreement will provide that on or before a specified date in each
year, a firm of independent public accountants will furnish a statement to the
Trustee to the effect that, on the basis of the examination by such firm
conducted substantially in compliance with the Uniform Single Attestation
Program for Mortgage Bankers or the Audit Program for Mortgages serviced for
FHLMC, the servicing by or on behalf of the Master Servicer
 
                                       55
 <PAGE>
<PAGE>
of mortgage loans or private asset backed securities, or under pooling and
servicing agreements substantially similar to each other (including the related
Agreement) was conducted in compliance with such agreements except for any
significant exceptions or errors in records that, in the opinion of the firm,
the Audit Program for Mortgages serviced for FHLMC, or the Uniform Single
Attestation Program for Mortgage Bankers, it is required to report. In rendering
its statement such firm may rely, as to matters relating to the direct servicing
of Loans by Sub-Servicers, upon comparable statements for examinations conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers or the Audit Program for Mortgages serviced for FHLMC (rendered
within one year of such statement) of firms of independent public accountants
with respect to the related Sub-Servicer.
 
     Each Agreement will also provide for delivery to the Trustee, on or before
a specified date in each year, of an annual statement signed by an officer of
the Master Servicer to the effect that the Master Servicer has fulfilled its
obligations under the Agreement throughout the preceding year.
 
     Copies of the annual accountants' statement and the statement of an officer
of the Master Servicer may be obtained by Securityholders of the related Series
without charge upon written request to the Master Servicer at the address set
forth in the related Prospectus Supplement.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The Master Servicer under each Pooling and Servicing Agreement or Master
Servicing Agreement, as applicable, will be named in the related Prospectus
Supplement. The entity serving as Master Servicer may be an affiliate of the
Depositor and may otherwise have normal business relationships with the
Depositor or the Depositor's affiliates.
 
     Each Agreement will provide that the Master Servicer may not resign from
its obligations and duties under the Agreement except upon a determination that
its duties thereunder are no longer permissible under applicable law. The Master
Servicer may, however, be removed from its obligations and duties as set forth
in the Agreement. No such resignation will become effective until the Trustee or
a successor servicer has assumed the Master Servicer's obligations and duties
under the Agreement.
 
     Each Agreement will further 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
Securityholders for any action taken or for refraining from the taking of any
action in good faith pursuant to the Agreement, or for errors in judgment;
provided, however, that neither the Master Servicer, the Depositor nor any such
person will be protected against any liability which would otherwise be imposed
by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. Each Agreement will further provide that the
Master Servicer, the Depositor and any director, officer, employee or agent of
the Master Servicer or the Depositor will be entitled to indemnification by the
related Trust Fund and will be held harmless against any loss, liability or
expense incurred in connection with any legal action relating to the Agreement
or the Securities, other than any loss, liability or expense related to any
specific Loan or Loans (except any such loss, liability or expense otherwise
reimbursable pursuant to the Agreement) and any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. In addition, each Agreement will provide that
neither the Master Servicer nor the Depositor will be under any obligation to
appear in, prosecute or defend any legal action which is not incidental to its
respective responsibilities under the Agreement and which in its opinion may
involve it in any expense or liability. The Master Servicer or the Depositor
may, however, in its discretion undertake any such action which it may deem
necessary or desirable with respect to the Agreement and the rights and duties
of the parties thereto and the interests of the Securityholders thereunder. In
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, as the case may be, will be entitled
to be reimbursed therefor out of funds otherwise distributable to
Securityholders.
 
     Except as otherwise specified in the related Prospectus Supplement, any
person into which the Master Servicer may be merged or consolidated, or any
person resulting from any merger or consolidation to which the Master Servicer
is a party, or any person succeeding to the business of the Master Servicer,
will be the successor of the Master Servicer under each Agreement, provided that
such person is qualified to sell mortgage loans to,
 
                                       56
 <PAGE>
<PAGE>
and service mortgage loans on behalf of, FNMA or FHLMC and further provided that
such merger, consolidation or succession does not adversely affect the then
current rating or ratings of the class or classes of Securities of such Series
that have been rated.
 
EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT
 
     Pooling and Servicing Agreement; Master Servicing Agreement. Except as
otherwise specified in the related Prospectus Supplement, Events of Default
under each Agreement will consist of (i) any failure by the Master Servicer to
distribute or cause to be distributed to Securityholders of any class any
required payment which continues unremedied for five days after the giving of
written notice of such failure to the Master Servicer by the Trustee or the
Depositor, or to the Master Servicer, the Depositor and the Trustee by the
holders of Securities of such class evidencing not less than 25% of the total
distributions allocated to such class ('Percentage Interests'); (ii) any failure
by the Master Servicer duly to observe or perform in any material respect any of
its other covenants or agreements in the Agreement, which failure materially
affects the rights of Securityholders and continues unremedied for thirty days
after the giving of written notice of such failure to the Master Servicer by the
Trustee or the Depositor, or to the Master Servicer, the Depositor and the
Trustee by the holders of Securities of any class evidencing not less than 25%
of the aggregate Percentage Interests constituting such class; and (iii) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding and certain actions by or on behalf of the
Master Servicer indicating its insolvency, reorganization or inability to pay
its obligations.
 
     If specified in the related Prospectus Supplement, the Agreement will
permit the Trustee to sell the Trust Fund Assets and the other assets of the
Trust Fund described under 'Credit Enhancement' herein in the event that
payments in respect thereto are insufficient to make payments required in the
Agreement. The assets of the Trust Fund will be sold only under the
circumstances and in the manner specified in the related Prospectus Supplement.
 
     Unless otherwise provided in the related Prospectus Supplement, so long as
an Event of Default under an Agreement remains unremedied, the Depositor or the
Trustee may, and at the direction of holders of Securities of any class
evidencing not less than 66 2/3% of the aggregate Percentage Interests
constituting such class and under such other circumstances as may be specified
in such Agreement, the Trustee shall terminate all of the rights and obligations
of the Master Servicer under the Agreement relating to such Trust Fund and in
and to the related Trust Fund Assets, whereupon the Trustee will succeed to all
of the responsibilities, duties and liabilities of the Master Servicer under the
Agreement, including, if specified in the related Prospectus Supplement, the
obligation to make Advances, and will be entitled to similar compensation
arrangements. In the event that the Trustee is unwilling or unable so to act, it
may appoint, or petition a court of competent jurisdiction for the appointment
of, a mortgage loan servicing institution with a net worth of a least
$10,000,000 to act as successor to the Master Servicer under the Agreement.
Pending such appointment, the Trustee is obligated to act in such capacity. The
Trustee and any such successor may agree upon the servicing compensation to be
paid, which in no event may be greater than the compensation payable to the
Master Servicer under the Agreement.
 
     Unless otherwise provided in the related Prospectus Supplement, no
Securityholder, solely by virtue of such holder's status as a Securityholder,
will have any right under any Agreement to institute any proceeding with respect
to such Agreement, unless such holder previously has given to the Trustee
written notice of default and unless the holders of Securities of any class of
such Series evidencing not less than 66 2/3% 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.
 
     Indenture. Except as otherwise specified in the related Prospectus
Supplement, Events of Default under the Indenture for each Series of Notes
include: (i) a default in the payment of any principal of or interest on any
Note of such Series which continues unremedied for five days after the giving of
written notice of such default is given as specified in the related Prospectus
Supplement; (ii) failure to perform in any material respect any other covenant
of the Depositor or the Trust Fund in the Indenture which continues for a period
of thirty (30) days after notice thereof is given in accordance with the
procedures described in the related Prospectus Supplement; (iii) certain events
of bankruptcy, insolvency, receivership or liquidation of the Depositor or the
Trust Fund; or (iv) any other Event of Default provided with respect to Notes of
that Series including but not
 
                                       57
 <PAGE>
<PAGE>
limited to certain defaults on the part of the issuer, if any, of a credit
enhancement instrument supporting such Notes.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, either the Trustee or the holders of a
majority of the then aggregate outstanding amount of the Notes of such Series
may declare the principal amount (or, if the Notes of that Series have an
interest rate of 0%, 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
more than 50% of the Percentage Interests of the Notes of such Series.
 
     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 distributions 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, other than a default in the payment of
any principal or interest on any Note of such Series for five days or more,
unless (a) the holders of 100% of the Percentage Interests 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 Percentage Interests of the Notes of
such Series.
 
     In the event that the Trustee liquidates the collateral in connection with
an Event of Default involving a default for five days or more in the payment of
principal of or interest on the Notes of a Series, 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 distribution 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.
 
     Except as otherwise specified in the related Prospectus Supplement, 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 which is unamortized.
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing with respect
to a Series of Notes, the Trustee shall be under no obligation to exercise any
of the rights or powers under the Indenture at the request or direction of any
of the holders of Notes of such Series, unless such holders offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in complying with such request or
direction. Subject to such provisions for indemnification and certain
limitations contained in the Indenture, the holders of a majority of the then
aggregate outstanding amount of the Notes of such Series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Notes of such Series, and the holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may, in
certain cases, waive any default with respect thereto, except a default in the
payment of principal or interest or a default in respect of a covenant or
provision of the Indenture that cannot be modified without the waiver or consent
of all the holders of the outstanding Notes of such Series affected thereby.
 
AMENDMENT
 
     Except as otherwise specified in the related Prospectus Supplement, each
Agreement may be amended by the Depositor, the Master Servicer and the Trustee,
without the consent of any of the Securityholders, (i) to cure any ambiguity or
mistake; (ii) to correct any defective provision therein or to supplement any
provision therein
 
                                       58
 <PAGE>
<PAGE>
which may be inconsistent with any other provision therein; (iii) to add to the
duties of the Depositor, the Seller or the Master Servicer; (iv) to add any
other provisions with respect to matters or questions arising thereunder or (v)
to modify, alter, amend, add to or rescind any of the terms or provisions
contained in such Agreement; provided, however, that any such action pursuant to
clauses (iv) or (v) above, will not, as evidenced by an opinion of counsel,
adversely affect in any material respect the interests of any Securityholder;
provided, however, that no opinion of counsel will be required if the person
requesting such amendment obtains a letter from each Rating Agency requested to
rate the class or classes of Securities of such Series stating that such
amendment will not result in the downgrading or withdrawal of the respective
ratings then assigned to such Securities. In addition, if a REMIC or FASIT
election is made with respect to a Trust Fund, the related Agreement may be
amended to modify, eliminate or add to any of its provisions to such extent as
may be necessary or helpful to maintain the qualification of the related Trust
Fund as a REMIC or as a FASIT, avoid or minimize the risk of the imposition of
any tax on the REMIC or FASIT or to comply with any other provision of the Code,
provided that the Trustee has received an opinion of counsel to the effect that
such action is necessary or helpful to maintain such qualification, avoid or
minimize the risk of imposition of such a tax or comply with any such
requirement of the Code, as the case may be. Except as otherwise specified in
the related Prospectus Supplement, each Agreement may also be amended by the
Depositor, the Master Servicer and the Trustee with the consent of holders of
Securities of such Series evidencing not less than 66 2/3% of the aggregate
Percentage Interests of each class affected thereby for the purpose of adding
any provisions to or changing in an manner or eliminating any of the provisions
of the Agreement or of modifying in any manner the rights of the holders of the
related Securities; provided, however, that no such amendment may (i) reduce in
any manner the amount of or delay the timing of, payments received on Loans
which are required to be distributed on any Security without the consent of the
holder of such Security, (ii) adversely affect in any material respect the
interests of the holders of any class of Securities in a manner other than as
described in the immediately preceding clause (i), without the consent of the
holders of Securities of such class evidencing not less than 66 2/3% of the
Percentage Interests of such class, or (iii) reduce the aforesaid percentage of
Securities of any class the holders of which are required to consent to any such
amendment without the consent of the holders of all Securities of such class
covered by such Agreement then outstanding. If a REMIC or FASIT election is made
with respect to a Trust Fund, the Trustee will not be entitled to consent to an
amendment to the related Agreement without having first received an opinion of
counsel to the effect that such amendment will not cause such Trust Fund to fail
to qualify as a REMIC or as a FASIT, as the case may be.
 
TERMINATION; OPTIONAL TERMINATION
 
     Pooling and Servicing Agreement; Trust Agreement. Unless otherwise
specified in the related Agreement, the obligations created by each Pooling and
Servicing Agreement and Trust Agreement for each Series of Securities will
terminate upon the payment to the related Securityholders of all amounts held in
the Security Account or by the Master Servicer and required to be paid to them
pursuant to such Agreement following the later of (i) the final payment of or
other liquidation of the last of the Trust Fund Assets subject thereto or the
disposition of all property acquired upon foreclosure of any such Trust Fund
Assets remaining in the Trust Fund and (ii) the purchase by the Master Servicer
or, if specified in the related Prospectus Supplement, by the holder of a call
right with respect to the Trust Fund Assets after the passage of a specified
period of time or after the principal balance of the Trust Fund Assets or the
Securities has been reduced to a specified level.
 
     Unless otherwise specified by the related Prospectus Supplement, any such
purchase of Trust Fund Assets and property acquired in respect of Trust Fund
Assets will be made at the option of the Master Servicer or such other person at
a price specified in the related Prospectus Supplement. The exercise of such
right will effect early retirement of the Securities of that Series, but the
right of the Master Servicer or such other person to so purchase is subject to
the principal balance of the related Trust Fund Assets being less than the
percentage specified in the related Prospectus Supplement of the aggregate
principal balance of the Trust Fund Assets at the Cut-off Date for the Series.
The foregoing is subject to the provision that if a REMIC election is made with
respect to a Trust Fund, any repurchase pursuant to clause (ii) above will be
made only in connection with a 'qualified liquidation' of the REMIC within the
meaning of Section 860F(g)(4) of the Code.
 
     Indenture. The Indenture will be discharged with respect to a Series of
Notes (except with respect to certain continuing rights specified in the
Indenture) upon the delivery to the Trustee for cancellation of all the Notes of
 
                                       59
 <PAGE>
<PAGE>
such Series or, with certain limitations, upon deposit with the Trustee of funds
sufficient for the payment in full of all of the Notes of such Series.
 
     In addition to such discharge with certain limitations, the Indenture will
provide that, if so specified with respect to the Notes of any Series, the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain obligations relating to temporary
Notes and exchange of Notes, to register the transfer of or exchange Notes of
such Series, to replace stolen, lost or mutilated Notes of such Series, to
maintain paying agencies and to hold monies for payment in trust) upon the
deposit with the Trustee, in trust, of money and/or direct obligations of or
obligations guaranteed by the United States of America which through the payment
of interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of and each
installment of interest on the Notes of such Series on the last scheduled
Distribution Date for such Notes and any installment of interest on such Notes
in accordance with the terms of the Indenture and the Notes of such Series. In
the event of any such defeasance and discharge of Notes of such Series, holders
of Notes of such Series would be able to look only to such money and/or direct
obligations for payment of principal and interest, if any, on their Notes until
maturity.
 
THE TRUSTEE
 
     The Trustee under each Agreement will be named in the applicable Prospectus
Supplement. The commercial bank or trust company serving as Trustee may have
normal banking relationships with the Depositor, the Master Servicer and any of
their respective affiliates.
 
                       CERTAIN LEGAL ASPECTS OF THE LOANS
 
     The following discussion contains summaries, which are general in nature,
of certain legal matters relating to the Loans. Because such legal aspects are
governed primarily by applicable state law (which laws may differ
substantially), the descriptions do not, except as expressly provided below,
reflect the laws of any particular state, nor encompass the laws of all states
in which the security for the Loans is situated. The descriptions are qualified
in their entirety by reference to the applicable federal laws and the
appropriate laws of the states in which Loans may be originated.
 
GENERAL
 
     The Loans for a Series may be secured by deeds of trust, mortgages,
security deeds or deeds to secure debt, depending upon the prevailing practice
in the state in which the property subject to the loan is located. Deeds of
trust are used almost exclusively in California instead of mortgages. A mortgage
creates a lien upon the real property encumbered by the mortgage, which lien is
generally not prior to the lien for real estate taxes and assessments. Priority
between mortgages depends on their terms and generally on the order of recording
with a state or county office. There are two parties to a mortgage, the
mortgagor, who is the borrower and owner of the mortgaged property, and the
mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. Although a deed of
trust is similar to a mortgage, a deed of trust formally has three parties, the
borrower-property owner called the trustor (similar to a mortgagor), a lender
(similar to a mortgagee) called the beneficiary, and a third-party grantee
called the trustee. Under a deed of trust, the borrower grants the property,
irrevocably until the debt is paid, in trust, generally with a power of sale, to
the trustee to secure payment of the obligation. A security deed and a deed to
secure debt are special types of deeds which indicate on their face that they
are granted to secure an underlying debt. By executing a security deed or deed
to secure debt, the grantor conveys title to, as opposed to merely creating a
lien upon, the subject property to the grantee until such time as the underlying
debt is repaid. The trustee's authority under a deed of trust, the mortgagee's
authority under a mortgage and the grantee's authority under a security deed or
deed to secure debt are governed by law and, with respect to some deeds of
trust, the directions of the beneficiary.
 
     Cooperatives. Certain of the Loans may be Cooperative Loans. The
Cooperative owns all the real property that comprises the project, including the
land, separate dwelling units and all common areas. The Cooperative is directly
responsible for project management and, in most cases, payment of real estate
taxes and hazard and liability insurance. If there is a blanket mortgage on the
Cooperative and/or underlying land, as is generally the case, the Cooperative,
as project mortgagor, is also responsible for meeting these mortgage
obligations. A
 
                                       60
 <PAGE>
<PAGE>
blanket mortgage is ordinarily incurred by the Cooperative in connection with
the construction or purchase of the Cooperative's apartment building. The
interest of the occupant under proprietary leases or occupancy agreements to
which that Cooperative is a party are generally subordinate to the interest of
the holder of the blanket mortgage in that building. If the Cooperative is
unable to meet the payment obligations arising under its blanket mortgage, the
mortgagee holding the blanket mortgage could foreclose on that mortgage and
terminate all subordinate proprietary leases and occupancy agreements. In
addition, the 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 lump sum at final maturity. The inability of the
Cooperative to refinance this mortgage and its consequent inability to make such
final payment could lead to foreclosure by the mortgagee providing the
financing. A foreclosure in either event by the holder of the blanket mortgage
could eliminate or significantly diminish the value of any collateral held by
the lender who financed the purchase by an individual tenant-stockholder of
Cooperative shares or, in the case of a Trust Fund including Cooperative Loans,
the collateral securing the Cooperative Loans.
 
     The Cooperative is owned by tenant-stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy agreements 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 rights is 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.
 
FORECLOSURE
 
     Deed of Trust. Foreclosure of a deed of trust is generally accomplished by
a non-judicial sale under a specific provision in the deed of trust which
authorizes the trustee to sell the property at public auction upon any default
by the borrower under the terms of the note or deed of trust. In certain states,
such foreclosure also may be accomplished by judicial action in the manner
provided for foreclosure of mortgages. In addition to any notice requirements
contained in a deed of trust, in some states (such as California), the trustee
must record a notice of default and send a copy to the borrower-trustor, to any
person who has recorded a request for a copy of any notice of default and notice
of sale, to any successor in interest to the borrower-trustor, to the
beneficiary of any junior deed of trust and to certain other persons. In some
states (including California), the borrower-trustor has the right to reinstate
the loan at any time following default until shortly before the trustee's sale.
In general, the borrower, or any other person having a junior encumbrance on the
real estate, may, during a statutorily prescribed reinstatement period, cure a
monetary default by paying the entire amount in arrears plus other designated
costs and expenses incurred in enforcing the obligation. Generally, state law
controls the amount of foreclosure expenses and costs, including attorney's
fees, which may be recovered by a lender. After the reinstatement period has
expired without the default having been cured, the borrower or junior lienholder
no longer has the right to reinstate the loan and must pay the loan in full to
prevent the scheduled foreclosure sale. If the deed of trust is not reinstated
within any applicable cure period, a notice of sale must be posted in a public
place and, in most states (including California), published for a specific
period of time in one or more newspapers. In addition, some state laws require
that a copy of the notice of sale be posted on the property and sent to all
parties having an interest of record in the real property.
 
     Mortgages. Foreclosure of a mortgage is generally accomplished by judicial
action. The action is initiated by the service of legal pleadings upon all
parties having an interest in the real property. Delays in completion of the
foreclosure may occasionally result from difficulties in locating necessary
parties. Judicial foreclosure proceedings are often not contested by any of the
parties. When the mortgagee's right to foreclosure is
 
                                       61
 <PAGE>
<PAGE>
contested, the legal proceedings necessary to resolve the issue can be time
consuming. After the completion of a judicial foreclosure proceeding, the court
generally issues a judgment of foreclosure and appoints a referee or other court
officer to conduct the sale of the property. In some states, mortgages may also
be foreclosed by advertisement, pursuant to a power of sale provided in the
mortgage.
 
     Although foreclosure sales are typically public sales, frequently no third
party purchaser bids in excess of the lender's lien because of the difficulty of
determining the exact status of title to the property, the possible
deterioration of the property during the foreclosure proceedings and a
requirement that the purchaser pay for the property in cash or by cashier's
check. Thus the foreclosing lender often purchases the property from the trustee
or referee for an amount equal to the principal amount outstanding under the
loan, accrued and unpaid interest and the expenses of foreclosure in which event
the mortgagor's debt will be extinguished or the lender may purchase for a
lesser amount in order to preserve its right against a borrower to seek a
deficiency judgment in states where such judgment is available. Thereafter,
subject to the right of the borrower in some states to remain in possession
during the redemption period, the lender will assume the burden of ownership,
including obtaining hazard insurance and making 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.
 
     Courts have imposed general equitable principles upon foreclosure, which
are generally designed to mitigate the legal consequences to the borrower of the
borrower's defaults under the loan documents. Some courts have been faced with
the issue of whether federal or state constitutional provisions reflecting due
process concerns for fair notice require that borrowers under deeds of trust
receive notice longer than that prescribed by statute. For the most part, these
cases have upheld the notice provisions as being reasonable or have found that
the sale by a trustee under a deed of trust does not involve sufficient state
action to afford constitutional protection to the borrower.
 
     When the beneficiary under a junior mortgage or deed of trust cures the
default and reinstates or redeems by paying the full amount of the senior
mortgage or deed of trust, the amount paid by the beneficiary so to cure or
redeem becomes a part of the indebtedness secured by the junior mortgage or deed
of trust. See 'Junior Mortgages; Rights of Senior Mortgagees' below.
 
     Cooperative Loans. The Cooperative shares owned by the tenant-stockholder
and pledged to the lender are, in almost all cases, subject to restrictions on
transfer as set forth in the Cooperative's certificate of incorporation and
bylaws, as well as the proprietary lease or occupancy agreement, and may be
cancelled by the Cooperative for failure by the tenant-stockholder to pay rent
or other obligations or charges owed by such tenant-stockholder, including
mechanics' liens against the cooperative apartment building incurred by such
tenant-stockholder. The proprietary lease or occupancy agreement generally
permits the Cooperative to terminate such lease or agreement in the event an
obligor fails to make payments or defaults in the performance of covenants
required thereunder. Typically, the lender and the Cooperative enter into a
recognition agreement which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the Cooperative will recognize the
lender's lien against proceeds from the sale of the Cooperative apartment,
subject, however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the Cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the Cooperative Loan and accrued and unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan, the lender must obtain the approval or consent of the
Cooperative as required by the proprietary lease before transferring
 
                                       62
 <PAGE>
<PAGE>
the Cooperative shares or assigning the proprietary lease. Generally, the lender
is not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with the provisions of Article 9 of the Uniform Commercial
Code (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 foreclosure sale has been conducted in a 'commercially
reasonable' manner will depend on the facts in each case. In determining
commercial reasonableness, a court will look to the notice given the debtor and
the method, manner, time, place and terms of the foreclosure. Generally, a sale
conducted according to the usual practice of banks selling similar collateral
will be considered reasonably conducted.
 
     Article 9 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 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.
 
     In the case of foreclosure on a building which was converted from a rental
building to a building owned by a Cooperative under a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property subject
to rent control and rent stabilization laws which apply to certain tenants who
elected to remain in the building but who did not purchase shares in the
Cooperative when the building was so converted.
 
ENVIRONMENTAL RISKS
 
     Real property pledged as security to a lender may be subject to unforeseen
environmental risks. Under the laws of certain states, contamination of a
property may give rise to a lien on the property to assure the payment of the
costs of clean-up. In several states such a lien has priority over the lien of
an existing mortgage against such property. In addition, under the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980
('CERCLA'), the United States Environmental Protection Agency ('EPA') may impose
a lien on property where EPA has incurred clean-up costs. However, a CERCLA lien
is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and under CERCLA, it is conceivable that a
secured lender may be held liable as an 'owner' or 'operator' for the costs of
addressing releases or threatened releases of hazardous substances at a
Property, even though the environmental damage or threat was caused by a prior
or current owner or operator. CERCLA imposes liability for such costs on any and
all 'responsible parties,' including owners or operators. However, CERCLA
excludes from the definition of 'owner or operator' a secured creditor who holds
indicia of ownership primarily to protect its security interest (the 'secured
creditor exclusion') but without 'participating in the management' of the
Property. Thus, if a lender's activities begin to encroach on the actual
management of a contaminated facility or property, the lender may incur
liability as an 'owner or operator' under CERCLA. Similarly, if a lender
forecloses and takes title to a contaminated facility or property, the lender
may incur CERCLA liability in various circumstances, including, but not limited
to, when it holds the facility or property as an investment (including leasing
the facility or property to third party), or fails to market the property in a
timely fashion.
 
     Whether actions taken by a lender would constitute participation in the
management of a mortgaged property, or the business of a borrower, so as to
render the secured creditor exemption unavailable to a lender has been a matter
of judicial interpretation of the statutory language, and court decisions have
been inconsistent. In 1990, the Court of Appeals for the Eleventh Circuit
suggested that the mere capacity of the lender to influence a borrower's
decisions regarding disposal of hazardous substances was sufficient
participation in the management of the borrower's business to deny the
protection of the secured creditor exemption to the lender.
 
     This ambiguity appears to have been resolved by the enactment of the Asset
Conservation, Lender Liability and Deposit Insurance Protection Act of 1996,
which was signed into law by President Clinton on September 30, 1996. This
legislation provides that in order to be deemed to have participated in the
management of a mortgaged property, a lender must actually participate in the
operational affairs of the property or the borrower. The legislation also
provides that participation in the management of the property does not include
'merely
 
                                       63
 <PAGE>
<PAGE>
having the capacity to influence, or unexercised right to control' operations.
Rather, a lender will lose the protection of the secured creditor exemption only
if it exercises decision-making control over the borrower's environmental
compliance and hazardous substance handling and disposal practices, or assumes
day-to-day management of all operational functions of the mortgaged property.
 
     If a lender is or becomes liable, it can bring an action for contribution
against any other 'responsible parties,' including a previous owner or operator,
who created the environmental hazard, but those persons or entities may be
bankrupt or otherwise judgment proof. The costs associated with environmental
cleanup may be substantial. It is conceivable that such costs arising from the
circumstances set forth above would result in a loss to Certificateholders.
 
     CERCLA does not apply to petroleum products, and the secured creditor
exclusion does not govern liability for cleanup costs under federal laws other
than CERCLA, in particular Subtitle I of the federal Resource Conservation and
Recovery Act ('RCRA'), which regulates underground petroleum storage tanks
(except heating oil tanks). The EPA has adopted a lender liability rule for
underground storage tanks under Subtitle I of RCRA. Under such rule, a holder of
a security interest in an underground storage tank or real property containing
an underground storage tank is not considered an operator of the underground
storage tank as long as petroleum is not added to, stored in or dispensed from
the tank. In addition, under the Asset Conservation, Lender Liability and
Deposit Insurance Protection Act of 1996, the protections accorded to lenders
under CERCLA are also accorded to the holders of security interests in
underground storage tanks. It should be noted, however, that liability for
cleanup of petroleum contamination may be governed by state law, which may not
provide for any specific protection for secured creditors, or alternatively, may
not impose liability on secured creditors at all.
 
     Except as otherwise specified in the related Prospectus Supplement, at the
time the Loans were originated, no environmental assessment or a very limited
environmental assessment of the Properties was conducted.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the borrower and foreclosed junior lienors are given a statutory
period in which to redeem the property from the foreclosure sale. In certain
other states (including California), this right of redemption applies only to
sales following judicial foreclosure, and not to sales pursuant to a
non-judicial power of sale. In most states where the right of redemption is
available, statutory redemption may occur upon payment of the foreclosure
purchase price, accrued interest and taxes. In other states, redemption may be
authorized if the former borrower pays only a portion of the sums due. The
effect of a statutory right of redemption is to diminish the ability of the
lender to sell the foreclosed property. The exercise of a right of redemption
would defeat the title of any purchaser from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run. In some states, there
is no right to redeem property after a trustee's sale under a deed of trust.
 
ANTI-DEFICIENCY LEGISLATION; BANKRUPTCY LAWS; TAX LIENS
 
     Certain states have imposed statutory and judicial restrictions that limit
the remedies of a beneficiary under a deed of trust or a mortgagee under a
mortgage. In some states, including California, statutes and case law limit the
right of the beneficiary or mortgagee to obtain a deficiency judgment against
borrowers financing the purchase of their residence or following sale under a
deed of trust or certain other foreclosure proceedings. A deficiency judgment is
a personal judgment against the borrower equal in most cases to the difference
between the amount due to the lender and the fair market value of the real
property at the time of the foreclosure sale. In certain states, including
California, if a lender simultaneously originates a loan secured by a senior
lien on a particular property and a loan secured by a junior lien on the same
property, such a lender as the holder of the junior lien may be precluded from
obtaining a deficiency judgment with respect to the excess of the aggregate
amount owed under both such loans over the proceeds of any sale under a deed of
trust or other foreclosure proceedings. As a result of these prohibitions, it is
anticipated that in most instances the Master Servicer will utilize the
non-judicial foreclosure remedy and will not seek deficiency judgments against
defaulting borrowers.
 
                                       64
 <PAGE>
<PAGE>
     Some state statutes require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting 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, when applicable, is that lenders
will usually proceed first against the security rather than bringing a personal
action against the borrower. In some states, exceptions to the anti-deficiency
statutes are provided for in certain instances where the value of the lender's
security has been impaired by acts or omissions of the borrower, for example, in
the event of waste of the property. Finally, other statutory provisions limit
any deficiency judgment against the former borrower following a foreclosure sale
to the excess of the outstanding debt over the fair market value of the property
at the time of the public sale. The purpose of these statutes is generally to
prevent a beneficiary or a mortgagee from obtaining a large deficiency judgment
against the former borrower as a result of low or no bids at the foreclosure
sale.
 
     Generally, Article 9 of the UCC governs foreclosure on Cooperative shares
and the related proprietary lease or occupancy agreement. 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.
 
     In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
and state laws affording relief to debtors, may interfere with or affect the
ability of the secured mortgage lender to realize upon its security. For
example, in a proceeding under the Bankruptcy Code, a lender may not foreclose
on a mortgaged property without the permission of the bankruptcy court. The
rehabilitation plan proposed by the debtor may provide, if the mortgaged
property is not the debtor's principal residence and the court determines that
the value of the mortgaged property is less than the principal balance of the
mortgage loan, for the reduction of the secured indebtedness to the value of the
mortgaged property as of the date of the commencement of the bankruptcy,
rendering the lender a general unsecured creditor for the difference, and also
may reduce the monthly payments due under such mortgage loan, change the rate of
interest and alter the mortgage loan repayment schedule. The effect of any such
proceedings under the Bankruptcy Code, including but not limited to any
automatic stay, could result in delays in receiving payments on the Loans
underlying a Series of Securities and possible reductions in the aggregate
amount of such payments.
 
     The federal tax laws provide priority to certain tax liens over the lien of
a mortgage or secured party.
 
DUE-ON-SALE CLAUSES
 
     Unless otherwise specified in the related Prospectus Supplement, each
conventional Loan will contain a due-on-sale clause which will generally provide
that if the mortgagor or obligor sells, transfers or conveys the Property, the
loan or contract may be accelerated by the mortgagee or secured party. Court
decisions and legislative actions have placed substantial restriction on the
right of lenders to enforce such clauses in many states. For instance, the
California Supreme Court in August 1978 held that due-on-sale clauses were
generally unenforceable. However, the Garn-St Germain Depository Institutions
Act of 1982 (the 'Garn-St Germain Act'), subject to certain exceptions, preempts
state constitutional, statutory and case law prohibiting the enforcement of
due-on-sale clauses. As a result, due-on-sale clauses have become generally
enforceable except in those states whose legislatures exercised their authority
to regulate the enforceability of such clauses with respect to mortgage loans
that were (i) originated or assumed during the 'window period' under the Garn-St
Germain Act which ended in all cases not later than October 15, 1982 and (ii)
originated by lenders other than national banks, federal savings institutions
and federal credit unions. FHLMC has taken the position in its published
mortgage servicing standards that, out of a total of eleven 'window period
states,' five states (Arizona, Michigan, Minnesota, New Mexico and Utah) have
enacted statutes extending, on various terms and for varying periods, the
prohibition on enforcement of due-on-sale clauses with respect to certain
categories of window period loans. Also, the Garn-St Germain Act does
'encourage' lenders to permit assumption of loans at the original rate of
interest or at some other rate less than the average of the original rate and
the market rate.
 
                                       65
 <PAGE>
<PAGE>
     As to loans secured by an owner-occupied residence, the Garn-St Germain Act
sets forth nine specific instances in which a mortgagee covered by the Act may
not exercise its rights under a due-on-sale clause, notwithstanding the fact
that a transfer of the property may have occurred. The inability to enforce a
due-on-sale clause may result in transfer of the related Property to an
uncreditworthy person, which could increase the likelihood of default or may
result in a mortgage bearing an interest rate below the current market rate
being assumed by a new home buyer, which may affect the average life of the
Loans and the number of Loans which may extend to maturity. In addition, under
federal bankruptcy law, due-on-sale clauses may not be enforceable in bankruptcy
proceedings and may, under certain circumstances, be eliminated in any modified
mortgage resulting from such bankruptcy proceeding.
 
ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES
 
     Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Under certain state laws, prepayment charges may not be imposed
after a certain period of time following the origination of mortgage loans with
respect to prepayments on loans secured by liens encumbering owner-occupied
residential properties. Since many of the Properties will be owner-occupied, it
is anticipated that prepayment charges may not be imposed with respect to many
of the Loans. The absence of such a restraint on prepayment, particularly with
respect to fixed rate Loans having higher Loan Rates, may increase the
likelihood of refinancing or other early retirement of such loans or contracts.
Late charges and prepayment fees are typically retained by servicers as
additional servicing compensation.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ('Title V') provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The Office of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized to
issue rules and regulations and to publish interpretations governing
implementation of Title V. The statute authorized the states to reimpose
interest rate limits by adopting, before April 1, 1983, a law or constitutional
provision 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. Certain states have taken action to reimpose interest rate limits
and/or to limit discount points or other charges.
 
THE HOME IMPROVEMENT CONTRACTS
 
     General. The Home Improvement Contracts other than those Home Improvement
Contracts that are unsecured or secured by mortgages on real estate (such Home
Improvement Contracts are hereinafter referred to in this section as
'contracts') generally are 'chattel paper' or constitute 'purchase money
security interests' each as defined in the UCC. Pursuant to the UCC, the sale of
chattel paper is treated in a manner similar to perfection of a security
interest in chattel paper. Under the related Agreement, the Depositor will
transfer physical possession of the contracts to the Trustee or a designated
custodian or may retain possession of the contracts as custodian for the
Trustee. In addition, the Depositor will make an appropriate filing of a UCC-1
financing statement in the appropriate states to, among other things, give
notice of the Trust Fund's ownership of the contracts. Unless otherwise
specified in the related Prospectus Supplement, the contracts will not be
stamped or otherwise marked to reflect their assignment from the Depositor to
the Trustee. Therefore, if through negligence, fraud or otherwise, a subsequent
purchaser were able to take physical possession of the contracts without notice
of such assignment, the Trust Fund's interest in the contracts could be
defeated.
 
     Security Interests in Home Improvements. The contracts that are secured by
the Home Improvements financed thereby grant to the originator of such contracts
a purchase money security interest in such Home Improvements to secure all or
part of the purchase price of such Home Improvements and related services. A
 
                                       66
 <PAGE>
<PAGE>
financing statement generally is not required to be filed to perfect a purchase
money security interest in consumer goods. Such purchase money security
interests are assignable. In general, a purchase money security interest grants
to the holder a security interest that has priority over a conflicting security
interest in the same collateral and the proceeds of such collateral. However, to
the extent that the collateral subject to a purchase money security interest
becomes a fixture, in order for the related purchase money security interest to
take priority over a conflicting interest in the fixture, the holder's interest
in such Home Improvement must generally be perfected by a timely fixture filing.
In general, a security interest does not exist under the UCC in ordinary
building material incorporated into an improvement on land. Home Improvement
Contracts that finance lumber, bricks, other types of ordinary building material
or other goods that are deemed to lose such characterization upon incorporation
of such materials into the related property, will not be secured by a purchase
money security interest in the Home Improvement being financed.
 
     Enforcement of Security Interest in Home Improvements. So long as the Home
Improvement has not become subject to the real estate law, a creditor can
repossess a Home Improvement securing a contract 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 contract 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 that the debtor may redeem
at or before such resale.
 
     Under the laws applicable in most states, a creditor is entitled to obtain
a deficiency judgment from a debtor for any deficiency on repossession and
resale of the property securing the debtor's loan. However, some states impose
prohibitions or limitations on deficiency judgments, and in many cases the
defaulting borrower would have no assets with which to pay a judgment.
 
     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.
 
     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 which 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 debtor thereunder. The effect of this
rule is to subject the assignee of such a contract to all claims and defenses
which the debtor could assert against the seller of goods. Liability under this
rule is limited to amounts paid under a contract; however, the obligor also may
be able to assert the rule to set off remaining amounts due as a defense against
a claim brought by the Trustee against such obligor. Numerous other federal and
state consumer protection laws impose requirements applicable to the
origination, servicing and enforcement of the contracts, 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 contract.
 
     Applicability of Usury Laws. Title V of the Depository Institutions
Deregulation and Monetary Control Act of 1980, as amended ('Title V'), provides
that, subject to the following conditions, state usury limitations shall not
apply to any contract which is secured by a first lien on certain kinds of
consumer goods. The contracts would be covered if they satisfy certain
conditions governing, among other things, 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 the related unit.
 
     Title V authorized any state to reimpose limitations on interest rates and
finance charges by adopting before April 1, 1983 a law or constitutional
provision which expressly rejects application of the federal law. Fifteen states
adopted such a law prior to the April 1, 1983 deadline. In addition, even where
Title V was not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on loans covered by Title V.
 
                                       67
 <PAGE>
<PAGE>
INSTALLMENT CONTRACTS
 
     The Loans may also consist of installment sale contracts. Under an
installment sale contract ('Installment Contract') the seller (hereinafter
referred to in this section as the 'lender') retains legal title to the property
and enters into an agreement with the purchaser hereinafter referred to in this
section as the 'borrower') for the payment of the purchase price, plus interest,
over the term of such contract. Only after full performance by the borrower of
the contract is the lender obligated to convey title to the property to the
purchaser. As with mortgage or deed of trust financing, during the effective
period of the Installment Contract, the borrower is generally responsible for
maintaining the property in good condition and for paying real estate taxes,
assessments and hazard insurance premiums associated with the property.
 
     The method of enforcing the rights of the lender under an Installment
Contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to its terms. The terms of Installment Contracts
generally provide that upon a default by the borrower, the borrower loses his or
her right to occupy the property, the entire indebtedness is accelerated, and
the buyer's equitable interest in the property is forfeited. The lender in such
a situation does not have to foreclose in order to obtain title to the property,
although in some cases a quiet title action is in order if the borrower has
filed the Installment Contract in local land records and an ejectment action may
be necessary to recover possession. In a few states, particularly in cases of
borrower default during the early years of an Installment Contract, the courts
will permit ejectment of the buyer and a forfeiture of his or her interest in
the property. However, most state legislatures have enacted provisions by
analogy to mortgage law protecting borrowers under Installment Contracts from
the harsh consequences of forfeiture. Under such statutes, a judicial or
nonjudicial foreclosure may be required, the lender may be required to give
notice of default and the borrower may be granted some grace period during which
the Installment Contract may be reinstated upon full payment of the default
amount and the borrower may have a post-foreclosure statutory redemption right.
In other states, courts in equity may permit a borrower with significant
investment in the property under an Installment Contract for the sale of real
estate to share in the proceeds of sale of the property after the indebtedness
is repaid or may otherwise refuse to enforce the forfeiture clause.
Nevertheless, generally speaking, the lender's procedures for obtaining
possession and clear title under an Installment Contract in a given state are
simpler and less time-consuming and costly than are the procedures for
foreclosing and obtaining clear title to a property subject to one or more
liens.
 
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 Loan (including a borrower who is a
member of the National Guard or is in reserve status at the time of the
origination of the Loan and is later called to active duty) may not be charged
interest above an annual rate of 6% during the period of 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 Master Servicer to collect
full amounts of interest on certain of the Loans. Unless otherwise provided in
the related Prospectus Supplement, any shortfall in interest collections
resulting from the application of the Relief Act could result in losses to
Securityholders. The Relief Act also imposes limitations which would impair the
ability of the Master Servicer to foreclose on an affected Loan during the
borrower's period of active duty status. Moreover, the Relief Act permits the
extension of a Loan's maturity and the re-adjustment of its payment schedule
beyond the completion of military service. Thus, in the event that such a Loan
goes into default, there may be delays and losses occasioned by the inability to
realize upon the Property in a timely fashion.
 
JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGEES
 
     To the extent that the Loans comprising the Trust Fund for a Series are
secured by mortgages which are junior to other mortgages held by other lenders
or institutional investors, the rights of the Trust Fund (and therefore the
Securityholders), as mortgagee under any such junior mortgage, are subordinate
to those of any mortgagee under any senior mortgage. The senior mortgagee has
the right to receive hazard insurance and condemnation proceeds and to cause the
property securing the Loan to be sold upon default of the mortgagor, thereby
extinguishing the junior mortgagee's lien unless the junior mortgagee asserts
its subordinate interest in the property in foreclosure litigation and,
possibly, satisfies the defaulted senior mortgage. A junior mortgagee
 
                                       68
 <PAGE>
<PAGE>
may satisfy a defaulted senior loan in full and, in some states, may cure a
default and bring the senior loan current, in either event adding the amounts
expended to the balance due on the junior loan. In most states, absent a
provision in the mortgage or deed of trust, no notice of default is required to
be given to a junior mortgagee.
 
     The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard insurance policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under senior mortgages will have the prior right to collect any
insurance proceeds payable under a hazard insurance policy and any award of
damages in connection with the condemnation and to apply the same to the
indebtedness secured by the senior mortgages. Proceeds in excess of the amount
of senior mortgage indebtedness, in most cases, may be applied to the
indebtedness of a junior mortgage.
 
     Another provision sometimes found in the form of the mortgage or deed of
trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which appear prior to the
mortgage or deed of trust, to provide and maintain fire insurance on the
property, to maintain and repair the property and not to commit or permit any
waste thereof, and to appear in and defend any action or proceeding purporting
to affect the property or the rights of the mortgagee under the mortgage. Upon a
failure of the mortgagor to perform any of these obligations, the mortgagee is
given the right under certain mortgages to perform the obligation itself, at its
election, with the mortgagor agreeing to reimburse the mortgagee for any sums
expended by the mortgagee on behalf of the mortgagor. All sums so expended by
the mortgagee become part of the indebtedness secured by the mortgage.
 
     The form of credit line trust deed or mortgage generally used by most
institutional lenders which make Revolving Credit Line Loans typically contains
a 'future advance' clause, which provides, in essence, that additional amounts
advanced to or on behalf of the borrower by the beneficiary or lender are to be
secured by the deed of trust or mortgage. Any amounts so advanced after the
Cut-off Date with respect to any Mortgage will not be included in the Trust
Fund. The priority of the lien securing any advance made under the clause may
depend in most states on whether the deed of trust or mortgage is called and
recorded as a credit line deed of trust or mortgage. If the beneficiary or
lender advances additional amounts, the advance is entitled to receive the same
priority as amounts initially advanced under the trust deed or mortgage,
notwithstanding the fact that there may be junior trust deeds or mortgages and
other liens which intervene between the date of recording of the trust deed or
mortgage and the date of the future advance, and notwithstanding that the
beneficiary or lender had actual knowledge of such intervening junior trust
deeds or mortgages and other liens at the time of the advance. In most states,
the trust deed or mortgage lien securing mortgage loans of the type which
includes home equity credit lines applies retroactively to the date of the
original recording of the trust deed or mortgage, provided that the total amount
of advances under the home equity credit line does not exceed the maximum
specified principal amount of the recorded trust deed or mortgage, except as to
advances made after receipt by the lender of a written notice of lien from a
judgment lien creditor of the trustor.
 
THE TITLE I PROGRAM
 
     General. Certain of the Loans contained in a Trust Fund may be loans
insured under the FHA Title I Credit Insurance program created pursuant to
Sections 1 and 2(a) of the National Housing Act of 1934 (the 'Title I Program').
Under the Title I Program, the FHA is authorized and empowered to insure
qualified lending institutions against losses on eligible loans. The Title I
Program operates as a coinsurance program in which the FHA insures up to 90% of
certain losses incurred on an individual insured loan, including the unpaid
principal balance of the loan, but only to the extent of the insurance coverage
available in the lender's FHA insurance coverage reserve account. The owner of
the loan bears the uninsured loss on each loan.
 
     The types of loans which are eligible for insurance by the FHA under the
Title I Program include property improvement loans ('Property Improvement Loans'
or 'Title I Loans'). A Property Improvement Loan or Title I Loan means a loan
made to finance actions or items that substantially protect or improve the basic
livability or utility of a property and includes single family improvement
loans.
 
                                       69

     There are two basic methods of lending or originating such loans which
include a 'direct loan' or a 'dealer loan'. With respect to a direct loan, the
borrower makes application directly to a lender without any assistance from a
dealer, which application may be filled out by the borrower or by a person
acting at the direction of the borrower who does not have a financial interest
in the loan transaction, and the lender may disburse the loan proceeds solely to
the borrower or jointly to the borrower and other parties to the transaction.
With respect to a dealer loan, the dealer, who has a direct or indirect
financial interest in the loan transaction, assists the borrower in preparing
the loan application or otherwise assists the borrower in obtaining the loan
from lender and the lender may distribute proceeds solely to the dealer or the
borrower or jointly to the borrower and the dealer or other parties. With
respect to a dealer Title I Loan, a dealer may include a seller, a contractor or
supplier of goods or services.
 
     Loans insured under the Title I Program are required to have fixed interest
rates and, generally, provide for equal installment payments due weekly,
biweekly, semi-monthly or monthly, except that a loan may be payable quarterly
or semi-annually in order to correspond with the borrower's irregular flow of
income. The first or last payments (or both) may vary in amount but may not
exceed 150% of the regular installment payment, and the first scheduled payment
may be due no later than two months from the date of the loan. The note must
contain a provision permitting full or partial prepayment of the loan. The
interest rate may be established by the lender and must be fixed for the term of
the loan and recited in the note. Interest on an insured loan must accrue from
the date of the loan and be calculated on a simple interest basis. The lender
must assure that the note and all other documents evidencing the loan are in
compliance with applicable federal, state and local laws.
 
     Each insured lender is required to use prudent lending standards in
underwriting individual loans and to satisfy the applicable loan underwriting
requirements under the Title I Program prior to its approval of the loan and
disbursement of loan proceeds. Generally, the lender must exercise prudence and
diligence to determine whether the borrower and any co-maker is solvent and an
acceptable credit risk, with a reasonable ability to make payments on the loan
obligation. The lender's credit application and review must determine whether
the borrower's income will be adequate to meet the periodic payments required by
the loan, as well as the borrower's other housing and recurring expenses, which
determination must be made in accordance with the expense-to-income ratios
published by the Secretary of HUD.
 
     Under the Title I Program, the FHA does not review or approve for
qualification for insurance the individual loans insured thereunder at the time
of approval by the lending institution (as is typically the case with other
federal loan programs). If, after a loan has been made and reported for
insurance under the Title I Program, the lender discovers any material
misstatement of fact or that the loan proceeds have been misused by the
borrower, dealer or any other party, it shall promptly report this to the FHA.
In such case, provided that the validity of any lien on the property has not
been impaired, the insurance of the loan under the Title I Program will not be
affected unless such material misstatements of fact or misuse of loan proceeds
was caused by (or was knowingly sanctioned by) the lender or its employees.
 
     Requirements for Title I Loans. The maximum principal amount for Title I
Loans must not exceed the actual cost of the project plus any applicable fees
and charges allowed under the Title I Program; provided that such maximum amount
does not exceed $25,000 (or the current applicable amount) for a single family
property improvement loan. Generally, the term of a Title I Loan may not be less
than six months nor greater than 20 years and 32 days. A borrower may obtain
multiple Title I Loans with respect to multiple properties, and a borrower may
obtain more than one Title I Loan with respect to a single property, in each
case as long as the total outstanding balance of all Title I Loans in the same
property does not exceed the maximum loan amount for the type of Title I Loan
thereon having the highest permissible loan amount.
 
     Borrower eligibility for a Title I Loan requires that the borrower have at
least a one-half interest in either fee simple title to the real property, a
lease thereof for a term expiring at least six months after the final maturity
of the Title I Loan or a recorded land installment contract for the purchase of
the real property, and that the borrower have equity in the property being
improved at least equal to the amount of the Title I Loan if such loan amount
exceeds $15,000. Any Title I Loan in excess of $7,500 must be secured by a
recorded lien on the improved property which is evidenced by a mortgage or deed
of trust executed by the borrower and all other owners in fee simple.
 
     The proceeds from a Title I Loan may be used only to finance property
improvements which substantially protect or improve the basic livability or
utility of the property as disclosed in the loan application. The Secretary of
HUD has published a list of items and activities which cannot be financed with
proceeds from any
 
                                       70
 <PAGE>
<PAGE>
Title I Loan and from time to time the Secretary of HUD may amend such list of
items and activities. With respect to any dealer Title I Loan, before the lender
may disburse funds, the lender must have in its possession a completion
certificate on a HUD approved form, signed by the borrower and the dealer. With
respect to any direct Title I Loan, the borrower is required to submit to the
lender, promptly upon completion of the improvements but not later than six
months after disbursement of the loan proceeds with one six month extension if
necessary, a completion certificate, signed by the borrower. The lender or its
agent is required to conduct an on-site inspection on any Title I Loan where the
principal obligation is $7,500 or more, and on any direct Title I Loan where the
borrower fails to submit a completion certificate.
 
     FHA Insurance Coverage. Under the Title I Program the FHA establishes an
insurance coverage reserve account for each lender which has been granted a
Title I insurance contract. The amount of insurance coverage in this account is
10% of the amount disbursed, advanced or expended by the lender in originating
or purchasing eligible loans registered with FHA for Title I insurance, with
certain adjustments. The balance in the insurance coverage reserve account is
the maximum amount of insurance claims the FHA is required to pay. Loans to be
insured under the Title I Program will be registered for insurance by the FHA
and the insurance coverage attributable to such loans will be included in the
insurance coverage reserve account for the originating or purchasing lender
following the receipt and acknowledgment by the FHA of a loan report on the
prescribed form pursuant to the Title I regulations. The FHA charges a fee of
0.50% per annum of the net proceeds (the original balance) of any eligible loan
so reported and acknowledged for insurance by the originating lender. The FHA
bills the lender for the insurance premium on each insured loan annually, on
approximately the anniversary date of the loan's origination. If an insured loan
is prepaid during the year, FHA will not refund the insurance premium, but will
abate any insurance charges falling due after such prepayment.
 
     Under the Title I Program the FHA will reduce the insurance coverage
available in the lender's FHA insurance coverage reserve account with respect to
loans insured under the lender's contract of insurance by (i) the amount of the
FHA insurance claims approved for payment relating to such insured loans and
(ii) the amount of insurance coverage attributable to insured loans sold by the
lender. The balance of the lender's FHA insurance coverage reserve account will
be further adjusted as required under Title I or by the FHA, and the insurance
coverage therein may be earmarked with respect to each or any eligible loans
insured thereunder, if a determination is made by the Secretary of HUD that it
is in its interest to do so. Originations and acquisitions of new eligible loans
will continue to increase a lender's insurance coverage reserve account balance
by 10% of the amount disbursed, advanced or expended in originating or acquiring
such eligible loans registered with the FHA for insurance under the Title I
Program. The Secretary of HUD may transfer insurance coverage between insurance
coverage reserve accounts with earmarking with respect to a particular insured
loan or group of insured loans when a determination is made that it is in the
Secretary's interest to do so.
 
     The lender may transfer (except as collateral in a bona fide loan
transaction) insured loans and loans reported for insurance only to another
qualified lender under a valid Title I contract of insurance. Unless an insured
loan is transferred with recourse or with a guaranty or repurchase agreement,
the FHA, upon receipt of written notification of the transfer of such loan in
accordance with the Title I regulations, will transfer from the transferor's
insurance coverage reserve account to the transferee's insurance coverage
reserve account an amount, if available, equal to 10% of the actual purchase
price or the net unpaid principal balance of such loan (whichever is less).
However, under the Title I Program not more than $5,000 in insurance coverage
shall be transferred to or from a lender's insurance coverage reserve account
during any October 1 to September 30 period without the prior approval of the
Secretary of HUD.
 
     Claims Procedures Under Title I. Under the Title I Program the lender may
accelerate an insured loan following a default on such loan only after the
lender or its agent has contacted the borrower in a face-to-face meeting or by
telephone to discuss the reasons for the default and to seek its cure. If the
borrower does not cure the default or agree to a modification agreement or
repayment plan, the lender will notify the borrower in writing that, unless
within 30 days the default is cured or the borrower enters into a modification
agreement or repayment plan, the loan will be accelerated and that, if the
default persists, the lender will report the default to an appropriate credit
agency. The lender may rescind the acceleration of maturity after full payment
is due and reinstate the loan only if the borrower brings the loan current,
executes a modification agreement or agrees to an acceptable repayment plan.
 
     Following acceleration of maturity upon a secured Title I Loan, the lender
may either (a) proceed against the property under any security instrument or
(b) make a claim under the lender's contract of insurance. If the
 
                                       71
 <PAGE>
<PAGE>
lender chooses to proceed against the property under a security instrument (or
if it accepts a voluntary conveyance or surrender of the property), the lender
may file an insurance claim only with the prior approval of the Secretary of
HUD.
 
     When a lender files an insurance claim with the FHA under the Title I
Program, the FHA reviews the claim, the complete loan file and documentation of
the lender's efforts to obtain recourse against any dealer who has agreed
thereto, certification of compliance with applicable state and local laws in
carrying out any foreclosure or repossession, and evidence that the lender has
properly filed proofs of claims, where the borrower is bankrupt or deceased.
Generally, a claim for reimbursement for loss on any Title I Loan must be filed
with the FHA no later than nine months after the date of default of such loan.
Concurrently with filing the insurance claim, the lender shall assign to the
United States of America the lender's entire interest in the loan note (or a
judgment in lieu of the note), in any security held and in any claim filed in
any legal proceedings. If, at the time the note is assigned to the United
States, the Secretary has reason to believe that the note is not valid or
enforceable against the borrower, the FHA may deny the claim and reassign the
note to the lender. If either such defect is discovered after the FHA has paid a
claim, the FHA may require the lender to repurchase the paid claim and to accept
a reassignment of the loan note. If the lender subsequently obtains a valid and
enforceable judgment against the borrower, the lender may resubmit a new
insurance claim with an assignment of the judgment. The FHA may contest any
insurance claim and make a demand for repurchase of the loan at any time up to
two years from the date the claim was certified for payment and may do so
thereafter in the event of fraud or misrepresentation on the part of the lender.
 
     Under the Title I Program the amount of an FHA insurance claim payment,
when made, is equal to the Claimable Amount, up to the amount of insurance
coverage in the lender's insurance coverage reserve account. For the purposes
hereof, the 'Claimable Amount' means an amount equal to 90% of the sum of: (a)
the unpaid loan obligation (net unpaid principal and the uncollected interest
earned to the date of default) with adjustments thereto if the lender has
proceeded against property securing such loan; (b) the interest on the unpaid
amount of the loan obligation from the date of default to the date of the
claim's initial submission for payment plus 15 calendar days (but not to exceed
9 months from the date of default), calculated at the rate of 7% per annum; (c)
the uncollected court costs; (d) the attorney's fees not to exceed $500; and
(e) the expenses for recording the assignment of the security to the United
States.
 
CONSUMER PROTECTION LAWS
 
     Numerous federal and state consumer protection laws impose substantive
requirements upon mortgage lenders in connection with the origination, servicing
and enforcement of loans secured by Single Family Properties. These laws include
the federal Truth-in-Lending Act and Regulation Z promulgated thereunder, Real
Estate Settlement Procedures Act and Regulation B promulgated thereunder, Equal
Credit Opportunity Act, Fair Credit Billing Act, Fair Credit Reporting Act and
related statutes and regulations. In particular, Regulation Z, requires certain
disclosures to the borrowers regarding the terms of the Loans; the Equal Credit
Opportunity Act and Regulation B promulgated thereunder prohibit discrimination
on the basis of age, race, color, sex, religion, marital status, national
origin, receipt of public assistance or the exercise of any right under the
Consumer Credit Protection Act, in the extension of credit; the Fair Credit
Reporting Act regulates the use and reporting of information related to the
borrower's credit experience. Certain provisions of these laws impose specific
statutory liabilities upon lenders who fail to comply therewith. In addition,
violations of such laws may limit the ability of the Sellers to collect all or
part of the principal of or interest on the Loans and could subject the Sellers
and in some cases their assignees to damages and administrative enforcement.

                        FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a summary of the anticipated material federal income tax
consequences of the purchase, ownership, and disposition of the Securities and
is based on advice of Brown & Wood LLP, special counsel to the Depositor. The
summary is based upon the provisions of the Code, the regulations promulgated
thereunder, including, where applicable, proposed regulations, and the judicial
and administrative rulings and decisions now in effect, all of which are subject
to change or possible differing interpretations. The statutory provisions,
regulations, and interpretations on which this summary is based are subject to
change, and such a change could apply retroactively.
 
     The summary does not purport to deal with all aspects of federal income
taxation that may affect particular investors in light of their individual
circumstances, nor with certain types of investors subject to special treatment
under the federal income tax laws. This summary focuses primarily upon investors
who will hold Securities as 'capital assets' (generally, property held for
investment) within the meaning of Section 1221 of the Code, but much of the
discussion is applicable to other investors as well. Prospective Investors are
advised to consult their own tax advisers concerning the federal, state, local
and any other tax consequences to them of the purchase, ownership and
disposition of the Securities.
 
     The federal income tax consequences to Securityholders will vary depending
on whether (i) the Securities of a Series are classified as indebtedness; (ii)
an election is made to treat the Trust Fund relating to a particular Series of
Securities as a REMIC or as a FASIT; (iii) the Securities represent interests in
a grantor trust; or (iv) the Trust Fund relating to a particular Series of
Certificates is classified as a partnership. The Prospectus Supplement for each
Series of Securities will specify how the Securities will be treated for federal
income tax purposes and will discuss whether a REMIC or a FASIT election, if
any, will be made with respect to such Series. Prior to issuance of each Series
of Securities, the Depositor shall file with the Commission a Form 8-K on behalf
of the related Trust Fund containing an opinion of Brown & Wood LLP with respect
to the validity of the information set forth under 'Federal Income Tax
Consequences' herein and in the related Prospectus Supplement.
 
TAXATION OF DEBT SECURITIES
 
     Interest and Acquisition Discount.  Securities representing regular
interests in a REMIC are generally treated as evidences of indebtedness issued
by the REMIC. Securities representing regular interests in a FASIT are treated
as debt instruments. Stated interest on regular interests in REMICs and regular
interests in FASITs will be taxable as ordinary income and taken into account
using the accrual method of accounting, regardless of the Securityholder's
normal accounting method. Thus, a taxpayer may be required to report income in
respect of a FASIT or REMIC regular interest before actually receiving a
corresponding cash distribution. Interest (other than original issue discount)
on Securities (other than Regular Interest Securities) that are characterized as
indebtedness for federal income tax purposes will be includible in income by
holders thereof in accordance with their usual methods of accounting. Securities
characterized as debt for federal income tax purposes, including regular
interests in REMICs or FASITs, will be referred to hereinafter collectively as
'Debt Securities'.
 
     Debt Securities that are Compound Interest Securities (i.e., debt
securities that accrete the amount of accrued interest and add that amount to
the principal balance of the securities until maturity or until some specified
event has occurred) will, and certain of the other Debt Securities may, be
issued with 'original issue discount' ('OID'). The following discussion is based
in part on the rules governing OID which are set forth in Sections 1271-1275 of
the Code and the Treasury regulations issued thereunder, (the 'OID
Regulations'). A Securityholder should be aware, however, that the OID
Regulations do not adequately address certain issues relevant to prepayable
securities, such as the Debt Securities.
 
     In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Debt Security and its issue price. A holder of
a Debt Security must include such OID in gross income as ordinary interest
income as it accrues under a method taking into account an economic accrual of
the discount. In general, OID must be included in income in advance of the
receipt of the cash representing that income. The amount of OID on a Debt
Security will be considered to be zero if it is less than a de minimis amount
determined under the Code.
 
                                       73
 <PAGE>
<PAGE>
     The issue price of a Debt Security is the first price at which a
substantial amount of Debt Securities of that class are sold (excluding sales to
bond houses, brokers, underwriters or wholesalers). If less than a substantial
amount of a particular class of Debt Securities is sold for cash on or prior to
the related Closing Date, the issue price for such class will be treated as the
fair market value of such class on such Closing Date. The issue price of a Debt
Security generally includes the amount paid by an initial Debt Security holder
for accrued interest that relates to a period prior to the issue date of the
Debt Security. ('pre-issuance accrued interest'). The issue price of a Debt
Security may, however, be computed without regard to such pre-issuance accrued
interest if such pre-issuance accrued interest will be paid on the first payment
date following the date of issuance. This alternative is available only if the
first payment date occurs within one year of the date of issuance. Under this
alternative, the payment of pre-issuance accrued interest will be treated as a
non-taxable return of capital and not as a payment of interest. The stated
redemption price at maturity of a Debt Security includes the original principal
amount of the Debt Security, but generally will not include stated interest if
it is 'qualified stated interest'.
 
     Under the OID Regulations, qualified stated interest generally means
interest payable at a single fixed rate or qualified variable rate (as described
below) provided that such interest payments are unconditionally payable at
intervals of one year or less during the entire term of the Debt Security. The
OID Regulations state that interest payments are unconditionally payable only if
a late payment or nonpayment is expected to be penalized or reasonable remedies
exist to compel payment or the Debt Security otherwise provides terms and
conditions that make the likelihood of late payment or nonpayment a remote
contingency. Certain Debt Securities may provide for default remedies in the
event of late payment or nonpayment of interest. The interest on such Debt
Securities will be unconditionally payable and constitute qualified stated
interest, not OID. However, absent clarification of the OID Regulations, where
Debt Securities do not provide for default remedies, the interest payments will
be included in the Debt Security's stated redemption price at maturity and taxed
as OID. Interest is payable at a single fixed rate only if the rate
appropriately takes into account the length of the interval between payments.
Distributions of interest on Debt Securities with respect to which deferred
interest will accrue, will not constitute qualified stated interest payments, in
which case the stated redemption price at maturity of such Debt Securities
includes all distributions of interest as well as principal thereon. Where the
interval between the issue date and the first Distribution Date on a Debt
Security is either longer or shorter than the interval between subsequent
Distribution Dates, all or part of the interest foregone, in the case of the
longer interval, and all of the additional interest, in the case of the shorter
interval, will be included in the stated redemption price at maturity and tested
under the de minimis rule described below. In the case of a Debt Security with a
long first period which has non-de minimis OID, all stated interest in excess of
interest payable at the effective interest rate for the long first period will
be included in the stated redemption price at maturity and the Debt Security
will generally have OID. Holders of Debt Securities should consult their own tax
advisors to determine the issue price and stated redemption price at maturity of
a Debt Security.
 
     Under the de minimis rule, OID on a Debt Security will be considered to be
zero if such OID is less than 0.25% of the stated redemption price at maturity
of the Debt Security multiplied by the weighted average maturity of the Debt
Security. For this purpose, the weighted average maturity of the Debt Security
is computed as the sum of the amounts determined by multiplying the number of
full years (i.e., rounding down partial years) from the issue date until each
distribution in reduction of stated redemption price at maturity is scheduled to
be made by a fraction, the numerator of which is the amount of each distribution
included in the stated redemption price at maturity of the Debt Security and the
denominator of which is the stated redemption price at maturity of the Debt
Security. Holders generally must report de minimis OID pro rata as principal
payments are received, and such income will be capital gain if the Debt Security
is held as a capital asset. However, accrual method holders may elect to accrue
all de minimis OID as well as market discount under a constant interest method.
 
     Debt Securities may provide for interest based on a qualified variable
rate. Under the OID Regulations, interest is treated as payable at a qualified
variable rate and not as contingent interest if, generally, (i) such interest is
unconditionally payable at least annually, (ii) the issue price of the debt
instrument does not exceed the total noncontingent principal payments and (iii)
interest is based on a 'qualified floating rate,' an 'objective rate,' or a
combination of 'qualified floating rates' that do not operate in a manner that
significantly accelerates or defers interest payments on such Debt Security. In
the case of Compound Interest Securities, certain Interest Weighted Securities
(as defined herein), and certain of the other Debt Securities, none of the
payments under the instrument will be considered qualified stated interest, and
thus the aggregate amount of all payments will be included in the stated
redemption price.
 
                                       74
 <PAGE>
<PAGE>
     The OID Regulations do not contain provisions specifically interpreting
Code Section 1272(a)(6). Until the Treasury issues guidance to the contrary, the
Trustee intends to base its computation on Code Section 1272(a)(6) and the OID
Regulations as described in this Prospectus. However, because no regulatory
guidance currently exists under Code Section 1272(a)(6), there can be no
assurance that such methodology represents the correct manner of calculating
OID.
 
     The holder of a Debt Security issued with OID must include in gross income,
for all days during its taxable year on which it holds such Debt Security, the
sum of the 'daily portions' of such original issue discount. The amount of OID
includible in income by a holder will be computed by allocating to each day
during a taxable year a pro rata portion of the original issue discount that
accrued during the relevant accrual period. In the case of a Debt Security that
is not a regular interest in a REMIC or a FASIT and the principal payments on
which are not subject to acceleration resulting from prepayments on the Loans,
the amount of OID includible in income of a Securityholder for an accrual period
(generally the period over which interest accrues on the debt instrument) will
equal the product of the yield to maturity of the Debt Security and the adjusted
issue price of the Debt Security, reduced by any payments of qualified stated
interest. The adjusted issue price is the sum of its issue price plus prior
accruals or OID, reduced by the total payments made with respect to such Debt
Security in all prior periods, other than qualified stated interest payments.
 
     The amount of OID to be included in income by a holder of a debt
instrument, such as certain classes of the Debt Securities, that is subject to
acceleration due to prepayments on other debt obligations securing such
instruments (a 'Pay-Through Security'), is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
'Prepayment Assumption'). The amount of OID that will accrue during an accrual
period on a Pay-Through Security is the excess (if any) of the sum of (a) the
present value of all payments remaining to be made on the Pay-Through Security
as of the close of the accrual period and (b) the payments during the accrual
period of amounts included in the stated redemption price of the Pay-Through
Security, over the adjusted issue price of the Pay-Through Security at the
beginning of the accrual period. The present value of the remaining payments is
to be determined on the basis of three factors: (i) the original yield to
maturity of the Pay-Through Security (determined on the basis of compounding at
the end of each accrual period and properly adjusted for the length of the
accrual period), (ii) events which have occurred before the end of the accrual
period and (iii) the assumption that the remaining payments will be made in
accordance with the original Prepayment Assumption. The effect of this method is
to increase the portions of OID required to be included in income by a holder to
take into account prepayments with respect to the Loans at a rate that exceeds
the Prepayment Assumption, and to decrease (but not below zero for any period)
the portions of original issue discount required to be included in income by a
holder of a Pay-Through Security to take into account prepayments with respect
to the Loans at a rate that is slower than the Prepayment Assumption. Although
original issue discount will be reported to holders of Pay-Through Securities
based on the Prepayment Assumption, no representation is made to holders that
Loans will be prepaid at that rate or at any other rate.
 
     The Depositor may adjust the accrual of OID on a class of Debt Securities
in a manner that it believes to be appropriate, to take account of realized
losses on the Loans, although the OID Regulations do not provide for such
adjustments. If the IRS were to require that OID be accrued without such
adjustments, the rate of accrual of OID for a class Debt Securities could
increase.
 
     Certain classes of Debt Securities may represent more than one class of
REMIC or FASIT regular interests. Unless otherwise provided in the related
Prospectus Supplement, the Trustee intends, based on the OID Regulations, to
calculate OID on such Securities as if, solely for the purposes of computing
OID, the separate regular interests were a single debt instrument.
 
     A subsequent holder of a Debt Security will also be required to include OID
in gross income, but such a holder who purchases such Debt Security for an
amount that exceeds its adjusted issue price will be entitled (as will an
initial holder who pays more than a Debt Security's issue price) to offset such
OID by comparable economic accruals of portions of such excess.
 
     Effects of Defaults and Delinquencies.  Holders will be required to report
income with respect to REMIC or FASIT regular interests under an accrual method
without giving effect to delays and reductions in distributions attributable to
a default or delinquency on the Loans, except possibly to the extent that it can
be established that such amounts are uncollectible. As a result, the amount of
income (including OID) reported by a holder of such a Security in any period
could significantly exceed the amount of cash distributed to such holder in that
period. The holder will eventually be allowed a loss (or will be allowed to
report a lesser amount of
 
                                       75
 <PAGE>
<PAGE>
income) to the extent that the aggregate amount of distributions on the
Securities is deducted as a result of a Loan default. However, the timing and
character of such losses or reductions in income are uncertain and, accordingly,
holders of Securities should consult their own tax advisors on this point.
 
     Interest Weighted Securities.  It is not clear how income should be accrued
with respect to REMIC or FASIT regular interests or Stripped Securities (as
defined under ' -- Tax Status as a Grantor Trust; General' herein) the payments
on which consist solely or primarily of a specified portion of the interest
payments on qualified mortgages held by the REMIC, on debt instruments held by
the FASIT, or on Loans underlying Pass-Through Securities ('Interest Weighted
Securities'). The Issuer intends to take the position that all of the income
derived from an Interest Weighted Security should be treated as OID and that the
amount and rate of accrual of such OID should be calculated by treating the
Interest Weighted Security as a Compound Interest Security. However, in the case
of Interest Weighted Securities that are entitled to some payments of principal
and that are REMIC or FASIT regular interests the Internal Revenue Service could
assert that income derived from an Interest Weighted Security should be
calculated as if the Security were a security purchased at a premium equal to
the excess of the price paid by such holder for such Security over its stated
principal amount, if any. Under this approach, a holder would be entitled to
amortize such premium only if it has in effect an election under Section 171 of
the Code with respect to all taxable debt instruments held by such holder, as
described below. Alternatively, the Internal Revenue Service could assert that
an Interest Weighted Security should be taxable under the rules governing bonds
issued with contingent payments. Such treatment may be more likely in the case
of Interest Weighted Securities that are Stripped Securities as described below.
See ' -- Tax Status as a Grantor Trust -- Discount or Premium on Pass-Through
Securities'.
 
     Variable Rate Debt Securities.  In the case of Debt Securities bearing
interest at a rate that varies directly, according to a fixed formula, with an
objective index, it appears that (i) the yield to maturity of such Debt
Securities and (ii) in the case of Pay-Through Securities, the present value of
all payments remaining to be made on such Debt Securities, should be calculated
as if the interest index remained at its value as of the issue date of such
Securities. Because the proper method of adjusting accruals of OID on a variable
rate Debt Security is uncertain, holders of variable rate Debt Securities should
consult their own tax advisers regarding the appropriate treatment of such
Securities for federal income tax purposes.
 
     Market Discount.  A purchaser of a Security may be subject to the market
discount rules of Sections 1276-1278 of the Code. A holder that acquires a Debt
Security with more than a prescribed de minimis amount of 'market discount'
(generally, the excess of the principal amount of the Debt Security over the
purchaser's purchase price) will be required to include accrued market discount
in income as ordinary income in each month, but limited to an amount not
exceeding the principal payments on the Debt Security received in that month
and, if the Securities are sold, the gain realized. Such market discount would
accrue in a manner to be provided in Treasury regulations but, until such
regulations are issued, such market discount would in general accrue either (i)
on the basis of a constant yield (in the case of a Pay-Through Security, taking
into account a prepayment assumption) or (ii) in the ratio of (a) in the case of
Securities (or in the case of a Pass-Through Security (as defined herein), as
set forth below, the Loans underlying such Security) not originally issued with
original issue discount, stated interest payable in the relevant period to total
stated interest remaining to be paid at the beginning of the period or (b) in
the case of Securities (or, in the case of a Pass-Through Security, as described
below, the Loans underlying such Security) originally issued at a discount, OID
in the relevant period to total OID remaining to be paid.
 
     Section 1277 of the Code provides that, regardless of the origination date
of the Debt Security (or, in the case of a Pass-Through Security, the Loans),
the excess of interest paid or accrued to purchase or carry a Security (or, in
the case of a Pass-Through Security, as described below, the underlying Loans)
with market discount over interest received on such Security is allowed as a
current deduction only to the extent such excess is greater than the market
discount that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, including upon the
sale, disposition, or repayment of the Security (or in the case of a
Pass-Through Security, an underlying Loan). A holder may elect to include market
discount in income currently as it accrues, on all market discount obligations
acquired by such holder during the taxable year such election is made and
thereafter, in which case the interest deferral rule will not apply.
 
     Premium.  A holder who purchases a Debt Security (other than an Interest
Weighted Security to the extent described above) at a cost greater than its
stated redemption price at maturity, generally will be considered to
 
                                       76
 <PAGE>
<PAGE>
have purchased the Security at a premium, which it may elect to amortize as an
offset to interest income on such Security (and not as a separate deduction
item) on a constant yield method. Although no regulations addressing the
computation of premium accrual on securities similar to the Securities have been
issued, the legislative history of the 1986 Act indicates that premium is to be
accrued in the same manner as market discount. Accordingly, it appears that the
accrual of premium on a class of Pay-Through Securities will be calculated using
the prepayment assumption used in pricing such class. If a holder makes an
election to amortize premium on a Debt Security, such election will apply to all
taxable debt instruments (including all REMIC and FASIT regular interests and
all pass-through certificates representing ownership interests in a trust
holding debt obligations) held by the holder at the beginning of the taxable
year in which the election is made, and to all taxable debt instruments acquired
thereafter by such holder, and will be irrevocable without the consent of the
IRS. Purchasers who pay a premium for the Securities should consult their tax
advisers regarding the election to amortize premium and the method to be
employed.
 
     Regulations dealing with amortizable bond premium specifically do not apply
to prepayable debt instruments described in Code Section 1272(a)(6) such as the
Securities. Absent further guidance from the IRS, the Trustee intends to account
for amortizable bond premium in the manner described above. Prospective
purchasers of the Securities should consult their tax advisors regarding the
possible application of the Amortizable Bond Premium Regulations.
 
     Election to Treat All Interest as Original Issue Discount.  The OID
Regulations permit a holder of a Debt Security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method for Debt Securities
acquired on or after April 4, 1994. If such an election were to be made with
respect to a Debt Security with market discount, the holder of the Debt Security
would be deemed to have made an election to include in income currently market
discount with respect to all other debt instruments having market discount that
such holder of the Debt Security acquires during the year of the election or
thereafter. Similarly, a holder of a Debt Security that makes this election for
a Debt Security that is acquired at a premium will be deemed to have made an
election to amortize bond premium with respect to all debt instruments having
amortizable bond premium that such holder owns or acquires. The election to
accrue interest, discount and premium on a constant yield method with respect to
a Debt Security is irrevocable.
 
TAXATION OF THE REMIC AND ITS HOLDERS
 
     General.  In the opinion of Brown & Wood LLP, special counsel to the
Depositor, if a REMIC election is made with respect to a Series of Securities,
then the arrangement by which the Securities of that Series are issued will be
treated as a REMIC as long as all of the provisions of the applicable Agreement
are complied with. Securities will be designated as 'Regular Interests' or
'Residual Interests' in a REMIC, as specified in the related Prospectus
Supplement.
 
     Except to the extent specified otherwise in a Prospectus Supplement, if a
REMIC election is made with respect to a Series of Securities, (i) Securities
held by a domestic building and loan association will constitute 'a regular or a
residual interest in a REMIC' within the meaning of Code Section
7701(a)(19)(C)(xi) (assuming that at least 95% of the REMIC's assets consist of
cash, government securities, 'loans secured by an interest in real property,'
and other types of assets described in Code Section 7701(a)(19)(C)); and (ii)
Securities held by a real estate investment trust will constitute 'real estate
assets' within the meaning of Code Section 856(c)(5)(B), and income with respect
to the Securities will be considered 'interest on obligations secured by
mortgages on real property or on interests in real property' within the meaning
of Code Section 856(c)(3)(B) (assuming, for both purposes, that at least 95% of
the REMIC's assets are qualifying assets). If less than 95% of the REMIC's
assets consist of assets described in (i) or (ii) above, then a Security will
qualify for the tax treatment described in (i), (ii) or (iii) in the proportion
that such REMIC assets are qualifying assets.
 
     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.
 
                                       77

REMIC EXPENSES; SINGLE CLASS REMICS
 
     As a general rule, all of the expenses of a REMIC will be taken into
account by holders of the Residual Interest Securities. In the case of a 'single
class REMIC,' however, the expenses will be allocated, under Treasury
regulations, among the holders of the Regular Interest Securities and the
holders of the Residual Interest Securities (as defined herein) on a daily basis
in proportion to the relative amounts of income accruing to each holder on that
day. In the case of a holder of a Regular Interest Security who is an individual
or a 'pass-through interest holder' (including certain pass-through entities but
not including real estate investment trusts), such expenses will be deductible
only to the extent that such expenses, plus other 'miscellaneous itemized
deductions' of the holder, exceed 2% of such holder's adjusted gross income. In
addition, for taxable years beginning after December 31, 1990, the amount of
itemized deductions otherwise allowable for the taxable year for an individual
whose adjusted gross income exceeds the applicable amount (which amount will be
adjusted for inflation for taxable years beginning after 1990) will be reduced
by the lesser of (i) 3% of the excess of adjusted gross income over the
applicable amount or (ii) 80% of the amount of itemized deductions otherwise
allowable for such taxable year. The reduction or disallowance of this deduction
may have a significant impact on the yield of the Regular Interest Security to
such a holder. In general terms, a single class REMIC is one that either (i)
would qualify, under existing Treasury regulations, as a grantor trust if it
were not a REMIC (treating all interests as ownership interests, even if they
would be classified as debt for federal income tax purposes) or (ii) is similar
to such a trust and which is structured with the principal purpose of avoiding
the single class REMIC rules. Unless otherwise specified in the related
Prospectus Supplement, the expenses of the REMIC will be allocated to holders of
the related residual interest securities.
 
TAXATION OF THE REMIC
 
     General.  Although a REMIC is a separate entity for federal income tax
purposes, a REMIC is not generally subject to entity-level tax. Rather, the
taxable income or net loss of a REMIC is taken into account by the holders of
residual interests. As described above, the regular interests are generally
taxable as debt of the REMIC.
 
     Calculation of REMIC Income.  The taxable income or net loss of a REMIC is
determined under an accrual method of accounting and in the same manner as in
the case of an individual, with certain adjustments. In general, the taxable
income or net loss will be the difference between (i) the gross income produced
by the REMIC's assets, including stated interest and any original issue discount
or market discount on loans and other assets and (ii) deductions, including
stated interest and original issue discount accrued on Regular Interest
Securities, amortization of any premium with respect to Loans, and servicing
fees and other expenses of the REMIC. A holder of a Residual Interest Security
that is an individual or a 'pass-through interest holder' (including certain
pass-through entities, but not including real estate investment trusts) will be
unable to deduct servicing fees payable on the loans or other administrative
expenses of the REMIC for a given taxable year, to the extent that such
expenses, when aggregated with such holder's other miscellaneous itemized
deductions for that year, do not exceed two percent of such holder's adjusted
gross income.
 
     For purposes of computing its taxable income or net loss, the REMIC should
have an initial aggregate tax basis in its assets equal to the aggregate fair
market value of the regular interests and the residual interests on the Startup
Day (generally, the day that the interests are issued). That aggregate basis
will be allocated among the assets of the REMIC in proportion to their
respective fair market values.
 
     The OID provisions of the Code apply to loans of individuals originated on
or after March 2, 1984, and the market discount provisions apply to loans
originated after July 18, 1984. Subject to possible application of the de
minimis rules, the method of accrual by the REMIC of OID income on such loans
will be equivalent to the method under which holders of Pay-Through Securities
accrue original issue discount (i.e., under the constant yield method taking
into account the Prepayment Assumption). The REMIC will deduct OID on the
Regular Interest Securities in the same manner that the holders of the Regular
Interest Securities include such discount in income, but without regard to the
de minimis rules. See 'Taxation of Debt Securities' above. However, a REMIC that
acquires loans at a market discount must include such market discount in income
currently, as it accrues, on a constant interest basis.
 
     To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the
 
                                       78
 <PAGE>
<PAGE>
life of the loans (taking into account the Prepayment Assumption) on a constant
yield method. Although the law is somewhat unclear regarding recovery of premium
attributable to loans originated on or before such date, it is possible that
such premium may be recovered in proportion to payments of loan principal.
 
     Prohibited Transactions and Contributions Tax.  The REMIC will be subject
to a 100% tax on any net income derived from a 'prohibited transaction'. For
this purpose, net income will be calculated without taking into account any
losses from prohibited transactions or any deductions attributable to any
prohibited transaction that resulted in a loss. In general, prohibited
transactions include: (i) subject to limited exceptions, the sale or other
disposition of any qualified mortgage transferred to the REMIC; (ii) subject to
a limited exception, the sale or other disposition of a cash flow investment;
(iii) the receipt of any income from assets not permitted to be held by the
REMIC pursuant to the Code; or (iv) the receipt of any fees or other
compensation for services rendered by the REMIC. It is anticipated that a REMIC
will not engage in any prohibited transactions in which it would recognize a
material amount of net income. In addition, subject to a number of exceptions, a
tax is imposed at the rate of 100% on amounts contributed to a REMIC after the
close of the three-month period beginning on the Startup Day. The holders of
Residual Interest Securities will generally be responsible for the payment of
any such taxes imposed on the REMIC. To the extent not paid by such holders or
otherwise, however, such taxes will be paid out of the Trust Fund and will be
allocated pro rata to all outstanding classes of Securities of such REMIC.
 
TAXATION OF HOLDERS OF RESIDUAL INTEREST SECURITIES
 
     The holder of a Security representing a residual interest (a 'Residual
Interest Security') will take into account the 'daily portion' of the taxable
income or net loss of the REMIC for each day during the taxable year on which
such holder held the Residual Interest Security. The daily portion is determined
by allocating to each day in any calendar quarter its ratable portion of the
taxable income or net loss of the REMIC for such quarter, and by allocating that
amount among the holders (on such day) of the Residual Interest Securities in
proportion to their respective holdings on such day.
 
     The holder of a Residual Interest Security must report its proportionate
share of the taxable income of the REMIC whether or not it receives cash
distributions from the REMIC attributable to such income or loss. The reporting
of taxable income without corresponding distributions could occur, for example,
in certain REMIC issues in which the loans held by the REMIC were issued or
acquired at a discount, since mortgage prepayments cause recognition of discount
income, while the corresponding portion of the prepayment could be used in whole
or in part to make principal payments on REMIC Regular Interests issued without
any discount or at an insubstantial discount (if this occurs, it is likely that
cash distributions will exceed taxable income in later years). Taxable income
may also be greater in earlier years of certain REMIC issues as a result of the
fact that interest expense deductions, as a percentage of outstanding principal
on REMIC Regular Interest Securities, will typically increase over time as lower
yielding Securities are paid, whereas interest income with respect to loans will
generally remain constant over time as a percentage of loan principal.
 
     In any event, because the holder of a residual interest is taxed on the net
income of the REMIC, the taxable income derived from a Residual Interest
Security in a given taxable year will not be equal to the taxable income
associated with investment in a corporate bond or stripped instrument having
similar cash flow characteristics and pretax yield. Therefore, the after-tax
yield on the Residual Interest Security may be less than that of such a bond or
instrument.
 
     Limitation on Losses.  The amount of the REMIC's net loss that a holder may
take into account currently is limited to the holder's adjusted basis at the end
of the calendar quarter in which such loss arises. A holder's basis in a
Residual Interest Security will initially equal such holder's purchase price,
and will subsequently be increased by the amount of the REMIC's taxable income
allocated to the holder, and decreased (but not below zero) by the amount of
distributions made and the amount of the REMIC's net loss allocated to the
holder. Any disallowed loss may be carried forward indefinitely, but may be used
only to offset income of the REMIC generated by the same REMIC. The ability of
holders of Residual Interest Securities to deduct net losses may be subject to
additional limitations under the Code, as to which such holders should consult
their tax advisers.
 
     Distributions.  Distributions on a Residual Interest Security (whether at
their scheduled times or as a result of prepayments) will generally not result
in any additional taxable income or loss to a holder of a Residual Interest
Security. If the amount of such payment exceeds a holder's adjusted basis in the
Residual Interest
 
                                       79
 <PAGE>
<PAGE>
Security, however, the holder will recognize gain (treated as gain from the sale
of the Residual Interest Security) to the extent of such excess.
 
     Sale or Exchange.  A holder of a Residual Interest Security will recognize
gain or loss on the sale or exchange of a Residual Interest Security equal to
the difference, if any, between the amount realized and such holder's adjusted
basis in the Residual Interest Security at the time of such sale or exchange.
Except to the extent provided in regulations, which have not yet been issued,
any loss upon disposition of a Residual Interest Security will be disallowed if
the selling holder acquires any residual interest in a REMIC or similar mortgage
pool within six months before or after such disposition.
 
     Excess Inclusions.  The portion of the REMIC taxable income of a holder of
a Residual Interest Security consisting of 'excess inclusion' income may not be
offset by other deductions or losses, including net operating losses, on such
holder's federal income tax return. Further, if the holder of a Residual
Interest Security is an organization subject to the tax on unrelated business
income imposed by Code Section 511, such holder's excess inclusion income will
be treated as unrelated business taxable income of such holder. In addition,
under Treasury regulations yet to be issued, if a real estate investment trust,
a regulated investment company, a common trust fund, or certain cooperatives
were to own a Residual Interest Security, a portion of dividends (or other
distributions) paid by the real estate investment trust (or other entity) would
be treated as excess inclusion income. If a Residual Security is owned by a
foreign person excess inclusion income is subject to tax at a rate of 30% which
may not be reduced by treaty, is not eligible for treatment as 'portfolio
interest' and is subject to certain additional limitations. See 'Tax Treatment
of Foreign Investors'. 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
excess inclusions for the year. Third, the amount of any alternative minimum tax
net operating loss deductions must be computed without regard to any excess
inclusions. 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.
 
     The excess inclusion portion of a REMIC's income is generally equal to the
excess, if any, of REMIC taxable income for the quarterly period allocable to a
Residual Interest Security, over the daily accruals for such quarterly period of
(i) 120% of the long term applicable federal rate on the Startup Day multiplied
by (ii) the adjusted issue price of such Residual Interest Security at the
beginning of such quarterly period. The adjusted issue price of a Residual
Interest at the beginning of each calendar quarter will equal its issue price
(calculated in a manner analogous to the determination of the issue price of a
Regular Interest), increased by the aggregate of the daily accruals for prior
calendar quarters, and decreased (but not below zero) by the amount of loss
allocated to a holder and the amount of distributions made on the Residual
Interest Security before the beginning of the quarter. The long-term federal
rate, which is announced monthly by the Treasury Department, is an interest rate
that is based on the average market yield of outstanding marketable obligations
of the United States government having remaining maturities in excess of nine
years.
 
     Under the REMIC Regulations, in certain circumstances, transfers of
Residual Securities may be disregarded. See ' -- Restrictions on Ownership and
Transfer of Residual Interest Securities' and ' -- Tax Treatment of Foreign
Investors' below.
 
     Restrictions on Ownership and Transfer of Residual Interest Securities.  As
a condition to qualification as a REMIC, reasonable arrangements must be made to
prevent the ownership of a REMIC residual interest by any 'Disqualified
Organization'. Disqualified Organizations include the United States, any State
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing, a rural
electric or telephone cooperative described in Section 1381(a)(2)(C) of the
Code, or any entity exempt from the tax imposed by Sections 1-1399 of the Code,
if such entity is not subject to tax on its unrelated business income.
Accordingly, the applicable Pooling and Servicing Agreement will prohibit
 
                                       80
 <PAGE>
<PAGE>
Disqualified Organizations from owning a Residual Interest Security. In
addition, no transfer of a Residual Interest Security will be permitted unless
the proposed transferee shall have furnished to the Trustee an affidavit
representing and warranting that it is neither a Disqualified Organization nor
an agent or nominee acting on behalf of a Disqualified Organization.
 
     If a Residual Interest Security is transferred to a Disqualified
Organization after March 31, 1988 (in violation of the restrictions set forth
above), a substantial tax can be imposed on the transferor of such Residual
Interest Security at the time of the transfer. In addition, if a Disqualified
Organization holds an interest in a pass-through entity after March 31, 1988
(including, among others, a partnership, trust, real estate investment trust,
regulated investment company, or any person holding as nominee), that owns a
Residual Interest Security, the pass-through entity will be required to pay an
annual tax on its allocable share of the excess inclusion income of the REMIC.
 
     Under the REMIC Regulations, if a Residual Interest Security is a
'noneconomic residual interest,' as described below, a transfer of a Residual
Interest Security to a United States person will be disregarded for all Federal
tax purposes unless no significant purpose of the transfer was to impede the
assessment or collection of tax. A Residual Interest Security is a 'noneconomic
residual interest' unless, at the time of the transfer (i) the present value of
the expected future distributions on the Residual Interest Security at least
equals the product of the present value of the anticipated excess inclusions and
the highest rate of tax for the year in which the transfer occurs and (ii) the
transferor reasonably expects that the transferee will receive distributions
from the REMIC at or after the time at which the taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes. If a
transfer of a Residual Interest is disregarded, the transferor would be liable
for any Federal income tax imposed upon taxable income derived by the transferee
from the REMIC. The REMIC Regulations provide no guidance as to how to determine
if a significant purpose of a transfer is to impede the assessment or collection
of tax. A similar type of limitation exists with respect to certain transfers of
residual interests by foreign persons to United States persons. See ' -- Tax
Treatment of Foreign Investors'.
 
     Mark to Market Rules.  Prospective purchasers of a REMIC Residual Interest
Security should be aware that a REMIC Residual Interest Security acquired after
January 3, 1995 cannot be marked-to-market.
 
ADMINISTRATIVE MATTERS
 
     The REMIC's books must be maintained on a calendar year basis and the REMIC
must file an annual federal income tax return. The REMIC will also be subject to
the procedural and administrative rules of the Code applicable to partnerships,
including the determination of any adjustments to, among other things, items of
REMIC income, gain, loss, deduction, or credit, by the IRS in a unified
administrative proceeding.
 
TAXATION OF THE FASIT AND ITS HOLDERS
 
     In the opinion of Brown & Wood LLP, special counsel to the Depositor, if a
FASIT election is made with respect to a Series of Securities, then the
arrangement by which the Securities of that Series are issued will be treated as
a FASIT so long as all of the provisions of the related Agreement are complied
with.
 
     The Small Business and Job Protection Act of 1996 added Sections 860H
through 860L to the Code (the 'FASIT Provisions'), which provide for a new type
of entity for federal income tax purposes known as a 'financial asset
securitization investment trust' (a 'FASIT'). Although the FASIT provisions of
the Code became effective on September 1, 1997, no Treasury regulations or other
administrative guidance have been issued with respect to those provisions.
Accordingly, definitive guidance cannot be provided with respect to many aspects
of the tax treatment of FASIT regular interest holders. Investors should also
note that the FASIT discussion contained herein constitutes only a summary of
the U.S. federal income tax consequences to the holders of FASIT interests. With
respect to each Series of FASIT regular interests, the related Prospectus
Supplement will provide a detailed discussion regarding the federal income tax
consequences associated with the particular transaction.
 
     FASIT interests will be classified as either FASIT regular interests, which
generally will be treated as debt for federal income tax purposes, or FASIT
ownership interests, which generally are not treated as debt for such purposes,
but rather as representing rights and responsibilities with respect to the
taxable income or loss of the related FASIT. The Prospectus Supplement for each
Series of Securities will indicate which Securities of such Series will be
designated as regular interests, and which, if any, will be designated as
ownership interests.
 
                                       81
 <PAGE>
<PAGE>
     Qualification as a FASIT.  A Trust Fund will qualify as a FASIT if (i) a
FASIT election is in effect, (ii) certain tests concerning (A) the composition
of the FASIT's assets and (B) the nature of the investors' interests in the
FASIT are met on a continuing basis, and (iii) the Trust Fund is not a regulated
investment company as defined in Section 851(a) of the Code.
 
     Asset Composition.  For a Trust Fund to be eligible for FASIT status,
substantially all of the Trust Fund Assets must consist of 'permitted assets' as
of the close of the third month beginning after the closing date and at all
times thereafter (the 'FASIT Qualification Test'). Permitted assets include (i)
cash or cash equivalents, (ii) debt instruments with fixed terms that would
qualify as regular interests if issued by a REMIC (generally, instruments that
provide for interest at a fixed rate, a qualifying variable rate, or a
qualifying interest-only ('IO') type rate), (iii) foreclosure property, (iv)
certain hedging instruments (generally, interest and currency rate swaps and
credit enhancement contracts) that are reasonably required to guarantee or hedge
against the FASIT's risks associated with being the obligor on FASIT interests,
(v) contract rights to acquire qualifying debt instruments or qualifying hedging
instruments, (vi) FASIT regular interest, and (vii) REMIC regular interests.
Permitted assets do not include any debt instruments issued by the holder of the
FASIT's ownership interest or by any person related to such holder.
 
     Interests in a FASIT.  In addition to the foregoing asset qualification
requirements, the interests in a FASIT also must meet certain requirements. All
of the interests in a FASIT must belong to either of the following: (i) one or
more classes of regular interests or (ii) a single class of ownership interest
that is held by a fully taxable domestic C Corporation.
 
     A FASIT interest generally qualifies as a regular interest if (i) it is
designated as a regular interest, (ii) it has a stated maturity no greater than
thirty years, (iii) it entitles its holder to a specified principal amount,
(iv) the issue price of the interest does not exceed 125% of its stated
principal amount, (v) the yield to maturity of the interest is less than the
applicable Treasury rate published by the IRS plus 5%, and (vi) if it pays
interest, such interest is payable at either (a) a fixed rate with respect to
the principal amount of the regular interest or (b) a permissible variable rate
with respect to such principal amount. Permissible variable rates for FASIT
regular interests are the same as those for REMIC regular interests (i.e.,
certain qualified floating rates and weighted average rates). Interest will
generally be considered to be based on a permissible variable rate if (i) such
interest is unconditionally payable at least annually, (ii) the issue price of
the debt instrument does not exceed the total noncontingent principal payments
and (iii) interest is based on a 'qualified floating rate,' an 'objective rate,'
a combination of a single fixed rate and one or more 'qualified floating rate,'
one 'qualified inverse floating rate,' or a combination of 'qualified floating
rates' that do not operate in a manner that significantly accelerates or defers
interest payments on such FASIT regular interest.
 
     If an interest in a FASIT fails to meet one or more of the requirements set
out in clauses (iii), (iv), or (v) in the immediately preceding paragraph, but
otherwise meets all requirements to be treated as a FASIT, it may still qualify
as a type of regular interest known as a 'High-Yield Interest'. In addition, if
an interest in a FASIT fails to meet the requirement of clause (vi), but the
interest payable on the interest consists of a specified portion of the interest
payments on permitted assets and that portion does not vary over the life of the
security, the interest will also qualify as a High-Yield Interest. A High-Yield
Interest may be held only by domestic C corporations that are fully subject to
corporate income tax ('Eligible Corporations'), other FASITs, and dealers in
securities who acquire such interests as inventory, rather than for investment.
In addition, holders of High-Yield Interests are subject to limitations on of
income derived from such interest.
 
     Consequences of Disqualification.  If a Trust Fund fails to comply with one
or more of ongoing requirements for FASIT status during any taxable year, the
Code provides that its FASIT status may be lost for that year and thereafter. If
FASIT status is lost, the treatment of the former FASIT and interests therein
for federal income tax purposes is uncertain. Although the Code authorizes the
Treasury to issue regulations that address situations where a failure to meet
the requirements for FASIT status occurs inadvertently and in good faith, such
regulations have not yet been issued. It is possible that disqualification
relief might be accompanied by sanctions, such as the imposition of a corporate
tax on all or a portion of the FASIT's income for the period of time in which
the requirements for FASIT status are not satisfied.

TREATMENT OF FASIT REGULAR INTERESTS
 
     Payments received by holders of FASIT regular interests generally will be
accorded the same tax treatment under the Code as payments received on other
taxable debt instruments. Holders of FASIT regular interests must report income
from such Securities under an accrual method of accounting, even if they
otherwise would have used the cash receipts and disbursements method. If the
FASIT regular interests is sold, the holder generally will recognize gain or
loss upon the sale. See ' -- Taxation of Debt Securities' above.
 
TREATMENT OF HIGH-YIELD INTEREST
 
     High-Yield Interests are subject to special rules regarding the eligibility
of holders of such interest, and the ability of such holders to offset income
derived from those interests with losses. High-Yield Interests only may be held
by Eligible Corporations, other FASITs, and dealers in securities who acquire
such interests as inventory. If a securities dealer (other than an Eligible
Corporation) initially acquires a High-Yield Interest as inventory, but later
begins to hold it for investment, the dealer will be subject to an excise tax
equal to the income from the High-Yield Interest multiplied by the highest
corporate income tax rate. In addition, transfers of High-Yield Interests to
disqualified holders will be disregarded for federal income tax purposes, and
the transferor will continue to be treated as the holder of the High-Yield
Interest.
 
     The holder of a High-Yield Interest may not use non-FASIT current losses or
net operating loss carryforwards or carrybacks to offset any income derived from
the High-Yield Interest, for either regular federal income tax purposes or for
alternative minimum tax purposes. In addition, the FASIT provisions contain an
anti-abuse rule that imposes corporate income tax on income derived from a FASIT
regular interest that is held by a pass-through entity (other than another
FASIT) that issues debt or equity securities backed by the FASIT regular
interest and that have the same features as High-Yield Interests.
 
TAX TREATMENT OF FASIT OWNERSHIP INTERESTS.
 
     A FASIT ownership interest represents the residual equity interest in a
FASIT. As such, the holder of a FASIT ownership interest determines its taxable
income by taking into account all assets, liabilities, and items of income,
gain, deduction, loss, and credit of a FASIT. In general, the character of the
income to the holder of a FASIT ownership interest will be the same as the
character of such income to the FASIT, except that any tax-exempt interest
income taken into account by the holder of a FASIT ownership interest is treated
as ordinary income. In determining that taxable income, the holder of a FASIT
ownership interest must determine the amount of interest, original issue
discount, market discount, and premium recognized with respect to the FASIT's
assets and the FASIT regular interests issued by the FASIT according to a
constant yield methodology and under an accrual method of accounting. In
addition, holders of FASIT Ownership Securities are subject to the same
limitations on their ability to use losses to offset income from their FASIT
regular interests as are holders of High-Yield Interest.
 
     Rules similar to the wash sale rules applicable to REMIC residual interests
also will apply to FASIT ownership interests. Accordingly, losses on
dispositions of a FASIT ownership interest generally will be disallowed where
within six months before or after the disposition, the seller of such interest
acquires any other FASIT ownership interest that is economically comparable to a
FASIT ownership interest. In addition, if any security that is sold or
contributed to a FASIT by the holders of the related FASIT ownership interest
was required to be marked-to-market under section 475 of the Code by such
holder, then section 475 of the Code will continue to apply to such securities,
except that the amount realized under the mark-to-market rules or the
securities' value after applying special valuation rules contained in the FASIT
provisions. Those special valuation rules generally require that the value of
debt instruments that are not traded on an established securities market be
determined by calculating the present value of the reasonably expected payments
under the instrument using a discount rate of 120% of the applicable Federal
rate, compounded semi-annually.
 
     The holder of a FASIT ownership interest will be subject to a tax equal to
100% of the net income derived by the FASIT from any 'prohibited transactions'.
Prohibited transactions include (i) the receipt of income derived from assets
that are not permitted assets, (ii) certain dispositions of permitted assets,
(iii) the receipt of any income derived from any loan originated by a FASIT, and
(iv) in certain cases, the receipt of income representing a servicing fee or
other compensation. Any Series of Securities for which a FASIT election is made
generally will be structured in order to avoid application of the prohibited
transaction tax.

<PAGE>
TAX STATUS AS A GRANTOR TRUST
 
     In the absence of a REMIC or FASIT election, a Trust Fund generally will be
classified as a grantor trust if (i) there is either only one class of
Securities that evidences the entire undivided beneficial ownership of the Trust
Fund Assets, or, if there is more than one class of Securities, each class
represents a direct investment in the Trust Fund Assets, and (ii) no power
exists under the related Agreement to vary the investment of the
Securityholders. If these conditions are satisfied, the related Prospectus
Supplement will recite that in the opinion of Brown & Wood LLP, special counsel
to the Depositor, the Trust Fund relating to a Series of Securities will be
classified for federal income tax purposes as a grantor trust under Subpart E,
Part I of Subchapter J of the Code (the Securities of such Series, 'Pass-Through
Securities'). In some Series there will be no separation of the principal and
interest payments on the Loans. In such circumstances, a holder will be
considered to have purchased a pro rata undivided interest in each of the Loans.
In other cases ('Stripped Securities'), sale of the Securities will produce a
separation in the ownership of all or a portion of the principal payments from
all or a portion of the interest payments on the Loans.
 
     Each holder must report on its federal income tax return its share of the
gross income derived from the Loans (not reduced by the amount payable as fees
to the Trustee and the Servicer and similar fees (collectively, the 'Servicing
Fee')), at the same time and in the same manner as such items would have been
reported under the holder's tax accounting method had it held its interest in
the Loans directly, received directly its share of the amounts received with
respect to the Loans, and paid directly its share of the Servicing Fees. In the
case of Pass-Through Securities other than Stripped Securities, such income will
consist of a pro rata share of all of the income derived from all of the Loans
and, in the case of Stripped Securities, such income will consist of a pro rata
share of the income derived from each stripped bond or stripped coupon in which
the holder owns an interest. The holder of a Security will generally be entitled
to deduct such Servicing Fees under Section 162 or Section 212 of the Code to
the extent that such Servicing Fees represent 'reasonable' compensation for the
services rendered by the Trustee and the Servicer (or third parties that are
compensated for the performance of services). In the case of a noncorporate
holder, however, Servicing Fees (to the extent not otherwise disallowed, e.g.,
because they exceed reasonable compensation) will be deductible in computing
such holder's regular tax liability only to the extent that such fees, when
added to other miscellaneous itemized deductions, exceed 2% of adjusted gross
income and may not be deductible to any extent in computing such holder's
alternative minimum tax liability. In addition, for taxable years beginning
after December 31, 1990, the amount of itemized deductions otherwise allowable
for the taxable year for an individual whose adjusted gross income exceeds the
applicable amount (which amount will be adjusted for inflation in taxable years
beginning after 1990) will be reduced by the lesser of (i) 3% of the excess of
adjusted gross income over the applicable amount or (ii) 80% of the amount of
itemized deductions otherwise allowable for such taxable year.
 
     Discount or Premium on Pass-Through Securities.  The holder's purchase
price of a Pass-Through Security is to be allocated among the Loans in
proportion to their fair market values, determined as of the time of purchase of
the Securities. In the typical case, the Trustee (to the extent necessary to
fulfill its reporting obligations) will treat each Loan as having a fair market
value proportional to the share of the aggregate principal balances of all of
the Loans that it represents, since the Securities, unless otherwise specified
in the related Prospectus Supplement, will have a relatively uniform interest
rate and other common characteristics. To the extent that the portion of the
purchase price of a Pass-Through Security allocated to a Loan (other than to a
right to receive any accrued interest thereon and any undistributed principal
payments) is less than or greater than the portion of the principal balance of
the Loan allocable to the Security, the interest in the Loan allocable to the
Pass-Through Security will be deemed to have been acquired at a discount or
premium, respectively.
 
     The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Loan with OID in excess of a
prescribed de minimis amount or a Stripped Security, a holder of a Security will
be required to report as interest income in each taxable year its share of the
amount of OID that accrues during that year in the manner described above. OID
with respect to a Loan could arise, for example, by virtue of the financing of
points by the originator of the Loan, or by virtue of the charging of points by
the originator of the Loan in an amount greater than a statutory de minimis
exception, in circumstances under which the points are not currently deductible
pursuant to applicable Code provisions. Any market discount or premium on a Loan
will be includible in income, generally in the manner described above, except
that in the case of Pass-Through Securities, market discount is calculated with
respect to the Loans underlying the Certificate, rather than with respect to the
Security. A holder that acquires an interest in a Loan originated after July 18,
 
                                       84
 <PAGE>
<PAGE>
1984 with more than a de minimis amount of market discount (generally, the
excess of the principal amount of the Loan over the purchaser's allocable
purchase price) will be required to include accrued market discount in income in
the manner set forth above. See ' -- Taxation of Debt Securities; Market
Discount' and ' -- Premium' above.
 
     In the case of market discount on a Pass-Through Security attributable to
Loans originated on or before July 18, 1984, the holder generally will be
required to allocate the portion of such discount that is allocable to a loan
among the principal payments on the Loan and to include the discount allocable
to each principal payment in ordinary income at the time such principal payment
is made. Such treatment would generally 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 in the preceding paragraph.
 
     Stripped Securities.  A Stripped Security may represent a right to receive
only a portion of the interest payments on the Loans, a right to receive only
principal payments on the Loans, or a right to receive certain payments of both
interest and principal. Certain Stripped Securities ('Ratio Strip Securities')
may represent a right to receive differing percentages of both the interest and
principal on each Loan. Pursuant to Section 1286 of the Code, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from ownership of the right to receive some or all of the principal
payments results in the creation of 'stripped bonds' with respect to principal
payments and 'stripped coupons' with respect to interest payments. Section 1286
of the Code applies the OID rules to stripped bonds and stripped coupons. For
purposes of computing original issue discount, a stripped bond or a stripped
coupon is treated as a debt instrument issued on the date that such stripped
interest is purchased with an issue price equal to its purchase price or, if
more than one stripped interest is purchased, the ratable share of the purchase
price allocable to such stripped interest.
 
     Servicing fees in excess of reasonable servicing fees ('excess servicing')
will be treated under the stripped bond rules. If the excess servicing fee is
less than 100 basis points (i.e., 1% interest on the Loan principal balance) or
the Securities are initially sold with a de minimis discount (assuming no
prepayment assumption is required), any non-de minimis discount arising from a
subsequent transfer of the Securities should be treated as market discount. The
IRS appears to require that reasonable servicing fees be calculated on a Loan by
Loan basis, which could result in some Loans being treated as having more than
100 basis points of interest stripped off.
 
     OID Regulations and judicial decisions provide no direct guidance as to how
the interest and original issue discount rules are to apply to Stripped
Securities and other Pass-Through Securities. Under the method described above
for Pay-Through Securities (the 'Cash Flow Bond Method'), a prepayment
assumption is used and periodic recalculations are made which take into account
with respect to each accrual period the effect of prepayments during such
period. However, the 1986 Act does not, absent Treasury regulations, appear
specifically to cover instruments such as the Stripped Securities which
technically represent ownership interests in the underlying Loans, rather than
being debt instruments 'secured by' those loans. For tax years beginning after
August 5, 1997 the Taxpayer Relief Act of 1997 may allow use of the Cash Flow
Bond Method with respect to Stripped Securities and other Pass-Through
Securities because it provides that such method applies to any pool of debt
instruments the yield on which may be affected by prepayments. Nevertheless, it
is believed that the Cash Flow Bond Method is a reasonable method of reporting
income for such Securities, and it is expected that OID will be reported on that
basis unless otherwise specified in the related Prospectus Supplement. In
applying the calculation to Pass-Through Securities, the Trustee will treat all
payments to be received by a holder with respect to the underlying Loans as
payments on a single installment obligation. The IRS could, however, assert that
original issue discount must be calculated separately for each Loan underlying a
Security.
 
     Under certain circumstances, if the Loans prepay at a rate faster than the
Prepayment Assumption, the use of the Cash Flow Bond Method may accelerate a
holder's recognition of income. If, however, the Loans prepay at a rate slower
than the Prepayment Assumption, in some circumstances the use of this method may
decelerate a holder's recognition of income.
 
     In the case of a Stripped Security that is an Interest Weighted Security,
the Trustee intends, absent contrary authority, to report income to Security
holders as OID, in the manner described above for Interest Weighted Securities.
 
                                       85
 <PAGE>
<PAGE>
     Possible Alternative Characterizations.  The characterizations of the
Stripped Securities described above are not the only possible interpretations of
the applicable Code provisions. Among other possibilities, the IRS could contend
that (i) in certain Series, each non-Interest Weighted Security is composed of
an unstripped undivided ownership interest in Loans and an installment
obligation consisting of stripped principal payments; (ii) the non-Interest
Weighted Securities are subject to the contingent payment provisions of the
Contingent Regulations; or (iii) each Interest Weighted Stripped Security is
composed of an unstripped undivided ownership interest in Loans and an
installment obligation consisting of stripped interest payments.
 
     Given the variety of alternatives for treatment of the Stripped Securities
and the different federal income tax consequences that result from each
alternative, potential purchasers are urged to consult their own tax advisers
regarding the proper treatment of the Securities for federal income tax
purposes.
 
     Character as Qualifying Loans.  In the case of Stripped Securities, there
is no specific legal authority existing regarding whether the character of the
Securities, for federal income tax purposes, will be the same as the Loans. The
IRS could take the position that the Loans' character is not carried over to the
Securities in such circumstances. Pass-Through Securities will be, and, although
the matter is not free from doubt, Stripped Securities should be considered to
represent 'real estate assets' within the meaning of Section 856(c)(5)(B) of the
Code and 'loans secured by an interest in real property' within the meaning of
Section 7701(a)(19)(C)(v) of the Code; and interest income attributable to the
Securities should be considered to represent 'interest on obligations secured by
mortgages on real property or on interests in real property' within the meaning
of Section 856(c)(3)(B) of the Code. Reserves or funds underlying the Securities
may cause a proportionate reduction in the above-described qualifying status
categories of Securities.
 
SALE OR EXCHANGE
 
     Subject to the discussion below with respect to Trust Funds classified as
partnerships made, a holder's tax basis in its Security is the price such holder
pays for a Security, plus amounts of original issue or market discount included
in income and reduced by any payments received (other than qualified stated
interest payments) and any amortized premium. Gain or loss recognized on a sale,
exchange, or redemption of a Security, measured by the difference between the
amount realized and the Security's basis as so adjusted, will generally be
capital gain or loss, assuming that the Security is held as a capital asset. In
the case of a Security held by a bank, thrift, or similar institution described
in Section 582 of the Code, however, gain or loss realized on the sale or
exchange of a REMIC or FASIT regular interest will be taxable as ordinary income
or loss. In addition, gain from the disposition of a REMIC regular interest that
might otherwise be capital gain will be treated as ordinary income to the extent
of the excess, if any, of (i) the amount that would have been includible in the
holder's income if the yield on such REMIC regular interest Security had equaled
110% of the applicable federal rate as of the beginning of such holder's holding
period, over the amount of ordinary income actually recognized by the holder
with respect to such REMIC regular interest. In general, the maximum tax rate on
ordinary income for individual taxpayers is 39.6% and the maximum tax rate on
long-term capital gains for such taxpayers is 28%. The maximum tax rate on both
ordinary income and long-term capital gains of corporate taxpayers is 35%.
 
     The Taxpayer Relief Act of 1997 reduces the maximum rates on long-term
capital gains recognized on capital assets held by individual taxpayers for more
than eighteen months as of the date of disposition (and would further reduce the
maximum rates on such gains in the year 2001 and thereafter for certain
individual taxpayers who meet specified conditions). Prospective investors
should consult their own tax advisors concerning these tax law changes.
 
MISCELLANEOUS TAX ASPECTS
 
     Backup Withholding.  Subject to the discussion below with respect to Trust
Funds classified as partnerships, a holder, other than a holder of a REMIC
Residual Security, may, under certain circumstances, be subject to 'backup
withholding' at a rate of 31% with respect to distributions or the proceeds of a
sale of certificates to or through brokers that represent interest or original
issue discount on the Securities. This withholding generally applies if the
holder of a Security (i) fails to furnish the Trustee with its taxpayer
identification number ('TIN'); (ii) furnishes the Trustee an incorrect TIN;
(iii) fails to report properly interest, dividends or other 'reportable
payments' as defined in the Code; or (iv) under certain circumstances, fails to
 
                                       86
 <PAGE>
<PAGE>
provide the Trustee or such holder's securities broker with a certified
statement, signed under penalty of perjury, that the TIN provided is its correct
number and that the holder is not subject to backup withholding. Backup
withholding will not apply, however, with respect to certain payments made to
holders, including payments to certain exempt recipients (such as exempt
organizations) and to certain Nonresidents (as defined below). holders should
consult their tax advisers as to their qualification for exemption from backup
withholding and the procedure for obtaining the exemption.
 
     The Trustee will report to the holders and to the Servicer for each
calendar year the amount of any 'reportable payments' during such year and the
amount of tax withheld, if any, with respect to payments on the Securities.
 
TAX TREATMENT OF FOREIGN INVESTORS
 
     Subject to the discussion below with respect to Trust Funds classified as
partnerships election is made, under the Code, unless interest (including OID)
paid on a Security (other than a Residual Interest Security) is considered to be
'effectively connected' with a trade or business conducted in the United States
by a nonresident alien individual, foreign partnership or foreign corporation
('Nonresidents'), such interest will normally qualify as portfolio interest
(except where (i) the recipient is a holder, directly or by attribution, of 10%
or more of the capital or profits interest in the issuer or (ii) the recipient
is a controlled foreign corporation to which the issuer is a related person) and
will be exempt from federal income tax. Upon receipt of appropriate ownership
statements, the issuer normally will be relieved of obligations to withhold tax
from such interest payments. These provisions supersede the generally applicable
provisions of United States law that would otherwise require the issuer to
withhold at a 30% rate (unless such rate were reduced or eliminated by an
applicable tax treaty) on, among other things, interest and other fixed or
determinable, annual or periodic income paid to Nonresidents. Holders of
Pass-Through Securities and Stripped Securities, including Ratio Strip
Securities, however, may be subject to withholding to the extent that the Loans
were originated on or before July 18, 1984.
 
     Interest and OID of Securityholders who are Nonresidents are not subject to
withholding if they are effectively connected with a United States business
conducted by the holder. They will, however, generally be subject to the regular
United States income tax.
 
     Payments to holders of Residual Interest Securities who are Nonresidents
will generally be treated as interest for purposes of the 30% (or lower treaty
rate) United States withholding tax. Holders should assume that such income does
not qualify for exemption from United States withholding tax as 'portfolio
interest'. It is clear that, to the extent that a payment represents a portion
of REMIC taxable income that constitutes excess inclusion income, a holder of a
Residual Interest Security will not be entitled to an exemption from or
reduction of the 30% (or lower treaty rate) withholding tax rule. If the
payments are subject to United States withholding tax, they generally will be
taken into account for withholding tax purposes only when paid or distributed
(or when the Residual Interest Security is disposed of). The Treasury has
statutory authority, however, to promulgate regulations which would require such
amounts to be taken into account at an earlier time in order to prevent the
avoidance of tax. Such regulations could, for example, require withholding prior
to the distribution of cash in the case of Residual Interest Securities that do
not have significant value. Under the REMIC Regulations, if a Residual Interest
Security has tax avoidance potential, a transfer of a Residual Interest Security
to a Nonresident will be disregarded for all federal tax purposes. A Residual
Interest Security has tax avoidance potential unless, at the time of the
transfer the transferor reasonably expects that the REMIC will distribute to the
transferee residual interest holder amounts that will equal at least 30% of each
excess inclusion, and that such amounts will be distributed at or after the time
at which the excess inclusions accrue and not later than the calendar year
following the calendar year of accrual. If a Nonresident transfers a Residual
Interest Security to a United States person, and if the transfer has the effect
of allowing the transferor to avoid tax on accrued excess inclusions, then the
transfer is disregarded and the transferor continues to be treated as the owner
of the Residual Interest Security for purposes of the withholding tax provisions
of the Code. See ' -- Excess Inclusions'.
 
TAX CHARACTERIZATION OF THE TRUST FUND AS A PARTNERSHIP
 
     In the absence of a REMIC or FASIT election, a Trust Fund that is not
classified as a grantor trust will be classified as a partnership for federal
tax purposes. Brown & Wood LLP, special counsel to the Depositor, will
 
                                       87
 <PAGE>
<PAGE>
deliver its opinion that a Trust Fund classified as a partnership will not be a
publicly traded partnership taxable as a corporation for federal income tax
purposes. This opinion will be based on the assumption that the terms of the
Trust Agreement and related documents will be complied with, and on counsel's
conclusions that the nature of the income of the Trust Fund will exempt it from
the rule that certain publicly traded partnerships are taxable as corporations
or the issuance of the Securities has been structured as a private placement
under an IRS safe harbor, so that the Trust Fund will not be characterized as a
publicly traded partnership taxable as a corporation.
 
     If the Trust Fund were taxable as a corporation for federal income tax
purposes, the Trust Fund would be subject to corporate income tax on its taxable
income. The Trust Fund's taxable income would include all its income, possibly
reduced by its interest expense on the Notes. Any such corporate income tax
could materially reduce cash available to make payments on the Notes and
distributions on the Certificates, and Certificateholders could be liable for
any such tax that is unpaid by the Trust Fund.
 
TAX CONSEQUENCES TO HOLDERS OF THE NOTES
 
     Treatment of the Notes as Indebtedness.  The Trust Fund will agree, and the
Noteholders will agree by their purchase of Notes, to treat the Notes as debt
for federal income tax purposes. Special counsel to the Depositor will, except
as otherwise provided in the related Prospectus Supplement, advise the Depositor
that the Notes will be classified as debt for federal income tax purposes. The
tax treatment of the Notes is described under the caption 'Taxation of Debt
Securities' set forth above.
 
TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES
 
     Treatment of the Trust Fund as a Partnership.  The Trust Fund and the
Master Servicer will agree, and the Certificateholders will agree by their
purchase of Certificates, to treat the Trust Fund as a partnership for purposes
of federal and state income tax, franchise tax and any other tax measured in
whole or in part by income, with the assets of the partnership being the assets
held by the Trust Fund, the partners of the partnership being the
Certificateholders, and the Notes being debt of the partnership. However, the
proper characterization of the arrangement involving the Trust Fund, the
Certificates, the Notes, the Trust Fund and the Servicer is not clear because
there is no authority on transactions closely comparable to that contemplated
herein.
 
     A variety of alternative characterizations are possible.  For example,
because the Certificates have certain features characteristic of debt, the
Certificates might be considered debt of the Trust Fund. Any such
characterization would not result in materially adverse tax consequences to
Certificateholders as compared to the consequences from treatment of the
Certificates as equity in a partnership, described below. The following
discussion assumes that the Certificates represent equity interests in a
partnership.
 
     Indexed Securities, etc.  The following discussion assumes that all
payments on the Certificates are denominated in U.S. dollars, none of the
Certificates are Indexed Securities or Strip Certificates, and that a Series of
Securities includes a single class of Certificates. If these conditions are not
satisfied with respect to any given Series of Certificates, additional tax
considerations with respect to such Certificates will be disclosed in the
applicable Prospectus Supplement.
 
     Partnership Taxation.  As a partnership, the Trust Fund will not be subject
to federal income tax. Rather, each Certificateholder will be required to
separately take into account such holder's allocated share of income, gains,
losses, deductions and credits of the Trust Fund. The Trust Fund's income will
consist primarily of interest and finance charges earned on the Loans (including
appropriate adjustments for market discount, OID and bond premium) and any gain
upon collection or disposition of Loans. The Trust Fund's deductions will
consist primarily of interest accruing with respect to the Notes, servicing and
other fees, and losses or deductions upon collection or disposition of Loans.
 
     The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (here, the
Trust Agreement and related documents). The Trust Agreement will provide, in
general, that the Certificateholders will be allocated taxable income of the
Trust Fund for each month equal to the sum of (i) the interest that accrues on
the Certificates in accordance with their terms for such month, including
interest accruing at the Pass-Through Rate for such month and interest on
amounts previously due on the Certificates but not yet distributed; (ii) any
Trust Fund income attributable to discount on the Loans that corresponds to any
excess of the principal amount of the Certificates over their initial issue
price (iii) prepayment premium payable to the Certificateholders for such month;
and (iv) any other
 
                                       88
 <PAGE>
<PAGE>
amounts of income payable to the Certificateholders for such month. Such
allocation will be reduced by any amortization by the Trust Fund of premium on
Loans that corresponds to any excess of the issue price of Certificates over
their principal amount. All remaining taxable income of the Trust Fund will be
allocated to the Company. Based on the economic arrangement of the parties, this
approach for allocating Trust Fund income should be permissible under applicable
Treasury regulations, although no assurance can be given that the IRS would not
require a greater amount of income to be allocated to Certificateholders.
Moreover, even under the foregoing method of allocation, Certificateholders may
be allocated income equal to the entire Pass-Through Rate plus the other items
described above even though the Trust Fund might not have sufficient cash to
make current cash distributions of such amount. Thus, cash basis holders will in
effect be required to report income from the Certificates on the accrual basis
and Certificateholders may become liable for taxes on Trust Fund income even if
they have not received cash from the Trust Fund to pay such taxes. In addition,
because tax allocations and tax reporting will be done on a uniform basis for
all Certificateholders but Certificateholders may be purchasing Certificates at
different times and at different prices, Certificateholders may be required to
report on their tax returns taxable income that is greater or less than the
amount reported to them by the Trust Fund.
 
     All of the taxable income allocated to a Certificateholder that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity
(including an individual retirement account) will constitute 'unrelated business
taxable income' generally taxable to such a holder under the Code.
 
     An individual taxpayer's share of expenses of the Trust Fund (including
fees to the Servicer but not interest expense) would be miscellaneous itemized
deductions. Such deductions might be disallowed to the individual in whole or in
part and might result in such holder being taxed on an amount of income that
exceeds the amount of cash actually distributed to such holder over the life of
the Trust Fund.
 
     The Trust Fund intends to make all tax calculations relating to income and
allocations to Certificateholders on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Loan, the Trust Fund
might be required to incur additional expense but it is believed that there
would not be a material adverse effect on Certificateholders.
 
     Discount and Premium.  It is believed that the Loans were not issued with
OID, and, therefore, the Trust Fund should not have OID income. However, the
purchase price paid by the Trust Fund for the Loans may be greater or less than
the remaining principal balance of the Loans at the time of purchase. If so, the
Loan will have been acquired at a premium or discount, as the case may be. (As
indicated above, the Trust Fund will make this calculation on an aggregate
basis, but might be required to recompute it on a Loan by Loan basis.)
 
     If the Trust Fund acquires the Loans at a market discount or premium, the
Trust Fund will elect to include any such discount in income currently as it
accrues over the life of the Loans or to any such premium against interest
income on the Loans. As indicated above, a portion of such market discount
income or premium deduction may be allocated to Certificateholders.
 
     Section 708 Termination.  Pursuant to final regulations issued on May 9,
1997 under Code Section 708, a sale or exchange of 50% or more of the capital
and profits in a partnership would cause a deemed contribution of assets of the
partnership (the 'old partnership') to a new partnership (the 'new partnership')
in exchange for interests in the new partnership. Such interests would be deemed
distributed to the partners of the old partnership in liquidation thereof, which
would not constitute a sale or exchange. Accordingly under these new
regulations, if the Trust Fund were characterized as a partnership and a sale of
Certificates terminated the partnership under Code Section 708, the purchaser's
basis in its ownership interest would not change.
 
     Disposition of Certificates.  Generally, capital gain or loss will be
recognized on a sale of Certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the Certificates sold.
A Certificateholder's tax basis in a Certificate will generally equal the
holder's cost increased by the holder's share of Trust Fund income (includible
in income) and decreased by any distributions received with respect to such
Certificate. In addition, both the tax basis in the Certificates and the amount
realized on a sale of a Certificate would include the holder's share of the
Notes and other liabilities of the Trust Fund. A holder acquiring Certificates
at different prices may be required to maintain a single aggregate adjusted tax
basis in such Certificates, and, upon sale or other disposition of some of the
Certificates, allocate a portion of such aggregate tax basis to the Certificates
sold (rather than maintaining a separate tax basis in each Certificate for
purposes of computing gain or loss on a sale of that Certificate).
 
                                       89

<PAGE>
     Any gain on the sale of a Certificate attributable to the holder's share of
unrecognized accrued market discount on the Loans would generally be treated as
ordinary income to the holder and would give rise to special tax reporting
requirements. The Trust Fund does not expect to have any other assets that would
give rise to such special reporting requirements. Thus, to avoid those special
reporting requirements, the Trust Fund will elect to include market discount in
income as it accrues.
 
     If a Certificateholder is required to recognize an aggregate amount of
income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.
 
     Allocations Between Transferors and Transferees.  In general, the Trust
Fund's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned among the Certificateholders
in proportion to the principal amount of Certificates owned by them as of the
close of the last day of such month. As a result, a holder purchasing
Certificates may be allocated tax items (which will affect its tax liability and
tax basis) attributable to periods before the actual transaction.
 
     The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust Fund might be reallocated among the Certificateholders. The Trust
Fund's method of allocation between transferors and transferees may be revised
to conform to a method permitted by future regulations.
 
     Section 754 Election.  In the event that a Certificateholder sells its
Certificates at a profit (loss), the purchasing Certificateholder will have a
higher (lower) basis in the Certificates than the selling Certificateholder had.
The tax basis of the Trust Fund's assets will not be adjusted to reflect that
higher (or lower) basis unless the Trust Fund were to file an election under
Section 754 of the Code. In order to avoid the administrative complexities that
would be involved in keeping accurate accounting records, as well as potentially
onerous information reporting requirements, the Trust Fund will not make such
election. As a result, Certificateholders might be allocated a greater or lesser
amount of Trust Fund income than would be appropriate based on their own
purchase price for Certificates.
 
     Administrative Matters.  The Owner Trustee is required to keep or have kept
complete and accurate books of the Trust Fund. Such books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the Trust Fund will be the calendar year. The Trustee will file a partnership
information return (IRS Form 1065) with the IRS for each taxable year of the
Trust Fund and will report each Certificateholder's allocable share of items of
Trust Fund income and expense to holders and the IRS on Schedule K-1. The Trust
Fund will provide the Schedule K-l information to nominees that fail to provide
the Trust Fund with the information statement described below and such nominees
will be required to forward such information to the beneficial owners of the
Certificates. Generally, holders must file tax returns that are consistent with
the information return filed by the Trust Fund or be subject to penalties unless
the holder notifies the IRS of all such inconsistencies.
 
     Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust Fund
with a statement containing certain information on the nominee, the beneficial
owners and the Certificates so held. Such information includes (i) the name,
address and taxpayer identification number of the nominee and (ii) as to each
beneficial owner (x) the name, address and identification number of such person,
(y) whether such person is a United States person, a tax-exempt entity or a
foreign government, an international organization, or any wholly owned agency or
instrumentality of either of the foregoing and (z) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust Fund information
as to themselves and their ownership of Certificates. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Trust Fund. The information referred to above
for any calendar year must be furnished to the Trust Fund on or before the
following January 31. Nominees, brokers and financial institutions that fail to
provide the Trust Fund with the information described above may be subject to
penalties.
 
     The Depositor will be designated as the tax matters partner in the related
Trust Agreement and, as such, will be responsible for representing the
Certificateholders in any dispute with the IRS. The Code provides for
 
                                       90
 <PAGE>
<PAGE>
administrative examination of a partnership as if the partnership were a
separate and distinct taxpayer. Generally, the statute of limitations for
partnership items does not expire before three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the Trust Fund by the appropriate taxing authorities
could result in an adjustment of the returns of the Certificateholders, and,
under certain circumstances, a Certificateholder may be precluded from
separately litigating a proposed adjustment to the items of the Trust Fund. An
adjustment could also result in an audit of a Certificateholder's returns and
adjustments of items not related to the income and losses of the Trust Fund.
 
     Tax Consequences to Foreign Certificateholders.  It is not clear whether
the Trust Fund would be considered to be engaged in a trade or business in the
United States for purposes of federal withholding taxes with respect to non-U.S.
Persons because there is no clear authority dealing with that issue under facts
substantially similar to those described herein. Although it is not expected
that the Trust Fund would be engaged in a trade or business in the United States
for such purposes, the Trust Fund will withhold as if it were so engaged in
order to protect the Trust Fund from possible adverse consequences of a failure
to withhold. The Trust Fund expects to withhold on the portion of its taxable
income, as calculated for this purpose which may exceed the distributions to
Certificateholders, that is allocable to foreign Certificateholders pursuant to
Section 1446 of the Code, as if such income were effectively connected to a U.S.
trade or business, at a rate of 35% for foreign holders that are taxable as
corporations and 39.6% for all other foreign holders. Subsequent adoption of
Treasury regulations or the issuance of other administrative pronouncements may
require the Trust Fund to change its withholding procedures. In determining a
holder's withholding status, the Trust Fund may rely on IRS Form W-8, IRS Form
W-9 or the holder's certification of nonforeign status signed under penalties of
perjury.
 
     The term 'U.S. Person' means a citizen or resident of the United States, a
corporation, partnership or (other entity treated as a corporation or
partnership) created or organized in or under the laws of the United States or
any state thereof including the District of Columbia (other than a partnership
that is not treated as a United States person under any applicable Treasury
regulations), or an estate whose income is subject to U.S. federal income tax
regardless of its source of income, or a trust if a court within the United
States is able to exercise primary supervision of the administration of the
trust and one or more United States persons have the authority to control all
substantial decisions of the trust. Notwithstanding the preceding sentence, to
the extent provided in regulations, certain trusts in existence on August 20,
1996 and treated as United States persons prior to such date that elect to
continue to be so treated also shall be considered U.S. Persons.
 
     Each foreign holder might be required to file a U.S. individual or
corporate income tax return (including, in the case of a corporation, the branch
profits tax) on its share of the Trust Fund's income. Each foreign holder must
obtain a taxpayer identification number from the IRS and submit that number to
the Trust Fund on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the Trust Fund taking the
position that no taxes were due because the Trust Fund was not engaged in a U.S.
trade or business. However, interest payments made (or accrued) to a
Certificateholder who is a foreign person generally will be considered
guaranteed payments to the extent such payments are determined without regard to
the income of the Trust Fund. If these interest payments are properly
characterized as guaranteed payments, then the interest will not be considered
'portfolio interest'. As a result, Certificateholders will be subject to United
States federal income tax and withholding tax at a rate of 30 percent, unless
reduced or eliminated pursuant to an applicable treaty. In such case, a foreign
holder would only be entitled to claim a refund for that portion of the taxes in
excess of the taxes that should be withheld with respect to the guaranteed
payments.
 
     Backup Withholding.  Distributions made on the Certificates and proceeds
from the sale of the Certificates will be subject to a 'backup' withholding tax
of 31% if, in general, the Certificateholder fails to comply with certain
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the Code.
 
                            STATE TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described in 'Federal
Income Tax Consequences,' potential investors should consider the state and
local income tax consequences of the acquisition, ownership, and disposition of
the Securities. State and local income tax law may differ substantially from the
corresponding federal law, and this discussion does not purport to describe any
aspect of the income tax laws of any state or
 
                                       91
 <PAGE>
<PAGE>
locality. Therefore, potential investors should consult their own tax advisors
with respect to the various state and local tax consequences of an investment in
the Securities.
 
                              ERISA CONSIDERATIONS
 
     The following describes certain considerations under ERISA and the Code,
which apply only to Securities of a Series that are not divided into subclasses.
If Securities are divided into subclasses the related Prospectus Supplement will
contain information concerning considerations relating to ERISA and the Code
that are applicable to such Securities.
 
     ERISA imposes requirements on employee benefit plans (and on certain other
retirement plans and arrangements, including individual retirement accounts and
annuities, Keogh plans and collective investment funds and separate accounts in
which such plans, accounts or arrangements are invested) (collectively 'Plans')
subject to ERISA and on persons who are fiduciaries with respect to such Plans.
Generally, ERISA applies to investments made by Plans. Among other things, ERISA
requires that the assets of Plans be held in trust and that the trustee, or
other duly authorized fiduciary, have exclusive authority and discretion to
manage and control the assets of such Plans. ERISA also imposes certain duties
on persons who are fiduciaries of Plans. Under ERISA, any person who exercises
any authority or control respecting the management or disposition of the assets
of a Plan is considered to be a fiduciary of such Plan (subject to certain
exceptions not here relevant). Certain employee benefit plans, such as
governmental plans (as defined in ERISA Section 3(32)) and, if no election has
been made under Section 410(d) of the Code, church plans (as defined in ERISA
Section 3(33)), are not subject to ERISA requirements. Accordingly, assets of
such plans may be invested in Securities without regard to the ERISA
considerations described above and below, subject to the provisions of
applicable state law. Any such plan which is qualified and exempt from taxation
under Code Sections 401(a) and 501(a), however, is subject to the prohibited
transaction rules set forth in Code Section 503.
 
     On November 13, 1986, the United States Department of Labor (the 'DOL')
issued final regulations concerning the definition of what constitutes the
assets of a Plan. (Labor Reg. Section 2510.3-101) Under this regulation, the
underlying assets and properties of corporations, partnerships and certain other
entities in which a Plan makes an 'equity' investment could be deemed for
purposes of ERISA to be assets of the investing Plan in certain circumstances.
However, the regulation provides that, generally, the assets of a corporation or
partnership in which a Plan invests will not be deemed for purposes of ERISA to
be assets of such Plan if the equity interest acquired by the investing Plan is
a publicly-offered security. A publicly-offered security, as defined in the
Labor Reg. Section 2510.3-101, is a security that is widely held, freely
transferable and registered under the Securities Exchange Act of 1934, as
amended.
 
     In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA prohibits a broad range of transactions
involving Plan assets and persons ('Parties in Interest') having certain
specified relationships to a Plan and imposes additional prohibitions where
Parties in Interest are fiduciaries with respect to such Plan. Because the Loans
may be deemed Plan assets of each Plan that purchases Securities, an investment
in the Securities by a Plan might be a prohibited transaction under ERISA
Sections 406 and 407 and subject to an excise tax under Code Section 4975 unless
a statutory or administrative exemption applies.
 
     In Prohibited Transaction Exemption 83-1 ('PTE 83-1'), which amended
Prohibited Transaction Exemption 81-7, the DOL exempted from ERISA's prohibited
transaction rules certain transactions relating to the operation of residential
mortgage pool investment trusts and the purchase, sale and holding of 'mortgage
pool pass-through certificates' in the initial issuance of such certificates.
PTE 83-1 permits, subject to certain conditions, transactions which might
otherwise be prohibited between Plans and Parties in Interest with respect to
those Plans related to the origination, maintenance and termination of mortgage
pools consisting of mortgage loans secured by first or second mortgages or deeds
of trust on single-family residential property, and the acquisition and holding
of certain mortgage pool pass-through certificates representing an interest in
such mortgage pools by Plans. If the general conditions (discussed below) of
PTE 83-1 are satisfied, investments by a Plan in Securities that represent
interests in a Pool consisting of Loans ('Single Family Securities') will be
exempt from the prohibitions of ERISA Sections 406(a) and 407 (relating
generally to transactions with Parties in Interest who are not fiduciaries) if
the Plan purchases the Single Family Securities at no more than fair market
value and will be exempt from the prohibitions of ERISA Sections 406(b)(1) and
(2) (relating generally to transactions with fiduciaries) if, in addition, the
purchase is approved by an independent fiduciary, no sales
 
                                       92
 <PAGE>
<PAGE>
commission is paid to the pool sponsor, the Plan does not purchase more than 25%
of all Single Family Securities, and at least 50% of all Single Family
Securities are purchased by persons independent of the pool sponsor or pool
trustee. PTE 83-1 does not provide an exemption for transactions involving
Subordinate Securities. Accordingly, unless otherwise provided in the related
Prospectus Supplement, no transfer of a Subordinate Security or a Security which
is not a Single Family Security may be made to a Plan.
 
     The discussion in this and the next succeeding paragraph applies only to
Single Family Securities. The Depositor believes that, for purposes of PTE 83-1,
the term 'mortgage pass-through certificate' would include: (i) Securities
issued in a Series consisting of only a single class of Securities; and (ii)
Securities issued in a Series in which there is only one class of those
particular Securities; provided that the Securities in the case of clause (i),
or the Securities in the case of clause (ii), evidence the beneficial ownership
of both a specified percentage of future interest payments (greater than 0%) and
a specified percentage (greater than 0%) of future principal payments on the
Loans. It is not clear whether a class of Securities that evidences the
beneficial ownership in a Trust Fund divided into Loan groups, beneficial
ownership of a specified percentage of interest payments only or principal
payments only, or a notional amount of either principal or interest payments, or
a class of Securities entitled to receive payments of interest and principal on
the Loans only after payments to other classes or after the occurrence of
certain specified events would be a 'mortgage pass-through certificate' for
purposes of PTE 83-1.
 
     PTE 83-1 sets forth three general conditions which must be satisfied for
any transaction to be eligible for exemption: (i) the maintenance of a system of
insurance or other protection for the pooled mortgage loans and property
securing such loans, and for indemnifying Securityholders against reductions in
pass-through payments due to property damage or defaults in loan payments in an
amount not less than the greater of one percent of the aggregate principal
balance of all covered pooled mortgage loans or the principal balance of the
largest covered pooled mortgage loan; (ii) the existence of a pool trustee who
is not an affiliate of the pool sponsor; and (iii) a limitation on the amount of
the payment retained by the pool sponsor, together with other funds inuring to
its benefit, to not more than adequate consideration for selling the mortgage
loans plus reasonable compensation for services provided by the pool sponsor to
the Pool. The Depositor believes that the first general condition referred to
above will be satisfied with respect to the Securities in a Series issued
without a subordination feature, or the Securities only in a Series issued with
a subordination feature, provided that the subordination and Reserve Account,
subordination by shifting of interests, the pool insurance or other form of
credit enhancement described under 'Credit Enhancement' herein (such
subordination, pool insurance or other form of credit enhancement being the
system of insurance or other protection referred to above) with respect to a
Series of Securities is maintained in an amount not less than the greater of one
percent of the aggregate principal balance of the Loans or the principal balance
of the largest Loan. See 'Description of the Securities' herein. In the absence
of a ruling that the system of insurance or other protection with respect to a
Series of Securities satisfies the first general condition referred to above,
there can be no assurance that these features will be so viewed by the DOL. The
Trustee will not be affiliated with the Depositor.
 
     Each Plan fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold Single Family Securities
must make its own determination as to whether the first and third general
conditions, and the specific conditions described briefly in the preceding
paragraph, of PTE 83-1 have been satisfied, or as to the availability of any
other prohibited transaction exemptions. Each Plan fiduciary should also
determine whether, under the general fiduciary standards of investment prudence
and diversification, an investment in the Securities is appropriate for the
Plan, taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.
 
     The DOL has granted to certain underwriters individual administrative
exemptions (the 'Underwriter Exemptions') 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 Underwriter Exemptions.
 
     While each Underwriter Exemption is an individual exemption separately
granted to a specific underwriter, the terms and conditions which generally
apply to the Underwriter Exemptions are substantially identical, and include the
following:
 
          (1) the acquisition of the certificates by a Plan is on terms
     (including the price for the certificates) that are at least as favorable
     to the Plan as they would be in an arm's-length transaction with an
     unrelated party;
 
                                       93
 <PAGE>
<PAGE>
          (2) the rights and interest evidenced by the certificates acquired by
     the Plan are not subordinated to the rights and interests evidenced by
     other certificates of the trust fund;
 
          (3) the certificates acquired by the Plan have received a rating at
     the time of such acquisition that is one of the three highest generic
     rating categories from Standard & Poor's Ratings Group, a Division of The
     McGraw-Hill Companies ('S&P'), Moody's Investors Service, Inc. ('Moody's'),
     Duff & Phelps Credit Rating Co. ('DCR') or Fitch IBCA, Inc. ('Fitch');
 
          (4) the trustee must not be an affiliate of any other member of the
     Restricted Group as defined below;
 
          (5) the sum of all payments made to and retained by the underwriters
     in connection with the distribution of the certificates represents not more
     than reasonable compensation for underwriting the certificates; the sum of
     all payments made to and retained by the seller pursuant to the assignment
     of the loans to the trust fund represents not more than the fair market
     value of such loans; the sum of all payments made to and retained by the
     servicer and any other servicer represents not more than reasonable
     compensation for such person's services under the agreement pursuant to
     which the loans are pooled and reimbursements of such person's reasonable
     expenses in connection therewith; and
 
          (6) the Plan investing in the certificates is 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 trust fund must also meet the following requirements:
 
          (i) the corpus of the trust fund must consist solely of assets of the
     type that have been included in other investment pools;
 
          (ii) certificates in such other investment pools must have been rated
     in one of the three highest rating categories of S&P, Moody's, Fitch or DCR
     for at least one year prior to the Plan's acquisition of certificates; and
 
          (iii) certificates evidencing interests 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 certificates.
 
     Moreover, the Underwriter Exemptions generally provide relief from certain
self-dealing/conflict of interest prohibited transactions that may occur when
the Plan fiduciary causes a Plan to acquire certificates in a trust as to which
the fiduciary (or its affiliate) is an obligor on the receivables held in the
trust provided that, among other requirements: (i) in the case of an acquisition
in connection with the initial issuance of certificates, at least fifty percent
(50%) of each class of certificates in which Plans have invested is acquired by
persons independent of the Restricted Group, (ii) such fiduciary (or its
affiliate) is an obligor with respect to five percent (5%) or less of the fair
market value of the obligations contained in the trust; (iii) the Plan's
investment in certificates of any class does not exceed twenty-five percent
(25%) of all of the certificates of that class outstanding at the time of the
acquisition; and (iv) immediately after the acquisition, no more than
twenty-five percent (25%) of the assets of the Plan with respect to which such
person is a fiduciary is invested in certificates representing an interest in
one or more trusts containing assets sold or serviced by the same entity. The
Underwriter Exemptions do not apply to Plans sponsored by the Seller, the
related Underwriter, the Trustee, the Master Servicer, any insurer with respect
to the Loans, any obligor with respect to Loans included in the Trust Fund
constituting more than five percent (5%) of the aggregate unamortized principal
balance of the assets in the Trust Fund, or any affiliate of such parties (the
'Restricted Group').
 
     The Prospectus Supplement for each Series of Securities will indicate the
classes of Securities, if any, offered thereby as to which it is expected that
an Underwriter Exemption will apply.
 
     The Underwriter Exemption contains several requirements, some of which
differ from those in PTE 83-l. The Underwriter Exemption contains an expanded
definition of 'certificate' which includes an interest which entitles the holder
to pass-through payments of principal, interest and/or other payments. The
Underwriter Exemption contains an expanded definition of 'trust' which permits
the trust corpus to consist of secured consumer receivables. The definition of
'trust,' however, does not include any investment pool unless, inter alia, (i)
the investment pool consists only of assets of the type which have been included
in other investment pools, (ii) certificates evidencing interests in such other
investment pools have been purchased by investors other than Plans for at least
one year prior to the Plan's acquisition of certificates pursuant to the
Underwriter Exemption and (iii) certificates in such other investment pools have
been rated in one of the three highest generic rating categories of the four
credit rating agencies noted below. Generally, the Underwriter Exemption holds
that the
 
                                       94
 <PAGE>
<PAGE>
acquisition of the certificates by a Plan must be on terms (including the price
for the certificates) that are at least as favorable to the Plan as they would
be in an arm's length transaction with an unrelated party. The Underwriter
Exemption requires that the rights and interests evidenced by the certificates
not be 'subordinated' to the rights and interests evidenced by other
certificates of the same trust. The Underwriter Exemption requires that
certificates acquired by a Plan have received a rating at the time of their
acquisition that is in one of the three highest generic rating categories of
S&P, Moody's, Fitch or DCR. The Underwriter Exemption specifies that the pool
trustee must not be an affiliate of the pool sponsor, nor an affiliate of the
Underwriter, the pool servicer, any obligor with respect to mortgage loans
included in the trust constituting more than five percent of the aggregate
unamortized principal balance of the assets in the trust, or any affiliate of
such entities. Finally, the Underwriter Exemption stipulates that any Plan
investing in the certificates must be an 'accredited investor' as defined in
Rule 501(a)(1) of Regulation D of the Securities and Exchange Commission under
the Securities Act of 1933.
 
     On July 21, 1997, the DOL published in the Federal Register an amendment to
the Underwriter Exemption which extends exemptive relief to certain
mortgage-backed and asset-backed securities transactions using pre-funding
accounts for trusts issuing pass-through certificates. The amendment generally
allows mortgage loans or other secured receivables (the 'obligations')
supporting payments to certificate-holders, and having a value equal to no more
than twenty-five percent (25%) of the total principal amount of the certificates
being offered by the trust, to be transferred to the trust within a 90-day or
three-month period following the closing date (the 'pre-funding period') instead
of requiring that all such obligations be either identified or transferred on or
before the closing date. The relief is available when the following conditions
are met:
 
          (1) The ratio of the amount allocated to the pre-funding account to
     the total principal amount of the certificates being offered (the
     'pre-funding limit') must not exceed twenty-five percent (25%).
 
          (2) All obligations transferred after the closing date (the
     'additional obligations') must meet the same terms and conditions for
     eligibility as the original obligations used to create the trust, which
     terms and conditions have been approved by a rating agency.
 
          (3) The transfer of such additional obligations to the trust during
     the pre-funding period must not result in the certificates to be covered by
     the Underwriter Exemption receiving a lower credit rating from a rating
     agency upon termination of the pre-funding period than the rating that was
     obtained at the time of the initial issuance of the certificates by the
     trust.
 
          (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 obligations in the trust at the end of the pre-funding period must not
     be more than 1.0% lower than the average interest rate for the obligations
     which were transferred to the trust on the closing date.
 
          (5) In order to ensure that the characteristics of the additional
     obligations are substantially similar to the original obligations which
     were transferred to the trust,
 
             (i) the characteristics of the additional obligations 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 each rating
        agency rating the certificates, the related underwriter and the related
        trustee) stating whether or not the characteristics of the additional
        obligations conform to the characteristics described in the related
        prospectus or prospectus supplement and/or pooling and servicing
        agreement. In preparing such letter, the independent accountant must use
        the same type of procedures as were applicable to the obligations which
        were transferred to the trust 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
     pre-funding account falls below the minimum level specified in the pooling
     and servicing agreement or an event of default occurs.
 
          (7) Amounts transferred to any pre-funding account and/or capitalized
     interest account used in connection with the pre-funding may be invested
     only in certain permitted investments.
 
          (8) The related prospectus supplement must describe:
 
             (i) any pre-funding account and/or capitalized interest account
        used in connection with a pre-funding account;
 
                                       95
 <PAGE>
<PAGE>
             (ii) the duration of the pre-funding period;
 
             (iii) the percentage and/or dollar amount of the pre-funding Limit
        for the trust; and
 
             (iv) that the amount remaining in the pre-funding account at the
        end of the pre-funding period will be remitted to certificate holders as
        repayments of principal.
 
          (9) The related pooling and servicing agreement must describe the
     permitted investments for the pre-funding account and/or capitalized
     interest account and, if not disclosed in the related prospectus or
     prospectus supplement, the terms and conditions for eligibility of
     additional obligations.
 
     Any Plan fiduciary which proposes to cause a Plan to purchase Securities
should consult with its counsel concerning the impact of ERISA and the Code, the
applicability of PTE 83-1 and the Underwriter Exemption, and the potential
consequences in their specific circumstances, prior to making such investment.
Moreover, each Plan fiduciary should determine whether under the general
fiduciary standards of investment prudence and diversification an investment in
the Securities is appropriate for the Plan, taking into account the overall
investment policy of the Plan and the composition of the Plan's investment
portfolio.
 
                                LEGAL INVESTMENT
 
     The Prospectus Supplement for each series of Securities will specify which,
if any, of the classes of Securities offered thereby constitute 'mortgage
related securities' for purposes of the Secondary Mortgage Market Enhancement
Act of 1984 ('SMMEA'). Classes of Securities that qualify as 'mortgage related
securities' will be legal investments for persons, trusts, corporations,
partnerships, associations, business trusts, and business entities (including
depository institutions, life insurance companies and pension funds) created
pursuant to or existing under the laws of the United States or of any state
(including the District of Columbia and Puerto Rico) whose authorized
investments are subject to state regulations to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any such entities. Under SMMEA, if a state enacts
legislation prior to October 4, 1991 specifically limiting the legal investment
authority of any such entities with respect to 'mortgage related securities,'
securities will constitute legal investments for entities subject to such
legislation only to the extent provided therein. Approximately twenty-one states
adopted such legislation prior to the October 4, 1991 deadline. SMMEA provides,
however, that in no event will the enactment of any such legislation affect the
validity of any contractual commitment to purchase, hold or invest in
securities, or require the sale or other disposition of securities, so long as
such contractual commitment was made or such securities were 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 in Securities
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase securities for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
24 (Seventh), subject in each case to such regulations as the applicable federal
authority may prescribe. In this connection, federal credit unions should review
the National Credit Union Administration ('NCUA') Letter to Credit Unions No.
96, as modified by Letter to Credit Unions No. 108, which includes guidelines to
assist federal credit unions in making investment decisions for mortgage related
securities and the NCUA's regulation 'Investment and Deposit Activities' (12
C.F.R. Part 703), which sets forth certain restrictions on investment by federal
credit unions in mortgage related securities (in each case whether or not the
class of Securities under consideration for purchase constituted a 'mortgage
related security'). The NCUA issued final regulations effective December 2, 1991
that restrict and in some instances prohibit the investment by Federal Credit
Unions in certain types of mortgage related securities.
 
     All depository institutions considering an investment in the Securities
(whether or not the class of Securities under consideration for purchase
constitutes a 'mortgage related security') should review the Federal Financial
Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
(the 'Policy Statement') setting forth, in relevant part, certain securities
trading and sales practices deemed unsuitable for an institution's investment
portfolio, and guidelines for (and restrictions on) investing in mortgage
derivative products, including 'mortgage related securities,' which are
'high-risk mortgage securities' as defined in the Policy Statement. According to
the Policy Statement, such 'high-risk mortgage securities' include securities
such as Securities not entitled to distributions allocated
 
                                       96
 <PAGE>
<PAGE>
to principal or interest, or Subordinated Securities. Under the Policy
Statement, it is the responsibility of each depository institution to determine,
prior to purchase (and at stated intervals thereafter), whether a particular
mortgage derivative product is a 'high-risk mortgage security,' and whether the
purchase (or retention) of such a product would be consistent with the Policy
Statement.
 
     The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to 'prudent investor' provisions, percentage-of-assets limits and provisions
which may restrict or prohibit investment in securities which are not 'interest
bearing' or 'income paying,' or in securities which are issued in book-entry
form.
 
     There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase Securities or to purchase
Securities representing more than a specified percentage of the investor's
assets. Investors should consult their own legal advisors in determining whether
and to what extent the Securities constitute legal investments for such
investors.
 
                             METHOD OF DISTRIBUTION
 
     Securities are being offered hereby in Series from time to time (each
Series evidencing or relating to a separate Trust Fund) through any of the
following methods:
 
          1. By negotiated firm commitment underwriting and public reoffering by
     underwriters;
 
          2. By agency placements through one or more placement agents primarily
     with institutional investors and dealers; and
 
          3. By placement directly by the Depositor with institutional
     investors.
 
     A Prospectus Supplement will be prepared for each Series which will
describe the method of offering being used for that Series and will set forth
the identity of any underwriters thereof and either the price at which such
Series is being offered, the nature and amount of any underwriting discounts or
additional compensation to such underwriters and the proceeds of the offering to
the Depositor, or the method by which the price at which the underwriters will
sell the Securities will be determined. Each Prospectus Supplement for an
underwritten offering will also contain information regarding the nature of the
underwriters' obligations, any material relationship between the Depositor and
any underwriter and, where appropriate, information regarding any discounts or
concessions to be allowed or reallowed to dealers or others and any arrangements
to stabilize the market for the Securities so offered. In firm commitment
underwritten offerings, the underwriters will be obligated to purchase all of
the Securities of such Series if any such Securities are purchased. Securities
may be acquired by the underwriters for their own accounts and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. In addition, if so stated in the related Prospectus
Supplement, such Prospectus Supplement and this Prospectus may be used by
Countrywide Securities Corporation, an affiliate of IndyMac ABS, Inc. and
IndyMac, Inc., in connection with offers and sales related to market making
transactions in the Securities in which Countrywide Securities Corporation acts
as principal. Countrywide Securities Corporation may also act as agent in such
transactions. Sales in such transactions will be made at prices related to
prevailing prices at the time of sale.
 
     Underwriters and agents may be entitled under agreements entered into with
the Depositor to indemnification by the Depositor against certain civil
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribution with respect to payments which such underwriters or agents
may be required to make in respect thereof.
 
     If a Series is offered other than through underwriters, the Prospectus
Supplement relating thereto 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.
 
                                 LEGAL MATTERS
 
     The validity of the Securities of each Series, including certain federal
income tax consequences with respect thereto, will be passed upon for the
Depositor by Brown & Wood LLP, One World Trade Center, New York, New York 10048.

                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Securities
and no Trust Fund will engage in any business activities or have any assets or
obligations prior to the issuance of the related Series of Securities.
Accordingly, no financial statements with respect to any Trust Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is a condition to the issuance of the Securities of each Series offered
hereby and by the Prospectus Supplement that they shall have been rated in one
of the four highest rating categories by the nationally recognized statistical
rating agency or agencies (each, a 'Rating Agency') specified in the related
Prospectus Supplement.
 
     Any such rating would be based on, among other things, the adequacy of the
value of the Trust Fund Assets and any credit enhancement with respect to such
class and will reflect such Rating Agency's assessment solely of the likelihood
that holders of a class of Securities of such class will receive payments to
which such Securityholders are entitled under the related Agreement. Such rating
will not constitute an assessment of the likelihood that principal prepayments
on the related Loans will be made, the degree to which the rate of such
prepayments might differ from that originally anticipated or the likelihood of
early optional termination of the Series of Securities. Such rating should not
be deemed a recommendation to purchase, hold or sell Securities, inasmuch as it
does not address market price or suitability for a particular investor. Each
security rating should be evaluated independently of any other security rating.
Such rating will not address the possibility that prepayment at higher or lower
rates than anticipated by an investor may cause such investor to experience a
lower than anticipated yield or that an investor purchasing a Security at a
significant premium might fail to recoup its initial investment under certain
prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series, such rating might also be lowered or withdrawn among other
reasons, because of an adverse change in the financial or other condition of a
credit enhancement provider or a change in the rating of such credit enhancement
provider's long term debt.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a Series of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of mortgage loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of mortgage loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that values of any Properties have remained
or will remain at their levels on the respective dates of origination of the
related Loans. If the residential real estate markets should experience an
overall decline in property values such that the outstanding principal balances
of the Loans in a particular Trust Fund and any secondary financing on the
related Properties become equal to or greater than the value of the Properties,
the rates of delinquencies, foreclosures and losses could be higher than those
now generally experienced in the mortgage lending industry. In additional,
adverse economic conditions (which may or may not affect real property values)
may affect the timely payment by mortgagors of scheduled payments of principal
and interest on the Loans and, accordingly, the rates of delinquencies,
foreclosures and losses with respect to any Trust Fund. To the extent that such
losses are not covered by credit enhancement, such losses will be borne, at
least in part, by the holders of one or more classes of the Securities of the
related Series.
