                                            your receipt of interest carried forward to later payment dates due
                                            to the Net Funds Cap. Interest on the notes will be calculated on the
                                            basis of the actual number of days elapsed in the Accrual Period and
                                            a 360-day year.

                                            Each "Accrual Period" is the period from and including the closing
                                            date, in respect of the first payment date, or the period from and
                                            including the immediately preceding payment date, in respect of all
                                            other payment dates, through but excluding the related payment date.

                                            prospectus supplement.

  Principal Payments......................  On each payment date, the notes will be due payments of principal.
                                            See "Description of the Notes--Payments on the Notes" in this
                                            prospectus supplement for a detailed discussion of the amount and
                                            timing of principal payments.

                                            The final payment of principal is scheduled to occur on the payment
                                            date occurring in March 2030 (the "Maturity Date"). The notes are
                                            expected to have received payments of principal in full by no later
                                            than the Maturity Date. However, the actual final payment date, on
                                            which the notes receive payment of principal in full, may occur

OTHER SECURITIES ISSUED...................  In addition to the notes, the issuer is also issuing residual
                                            interest certificates that evidence the residual interest in the
                                            assets of the issuer. The residual interest certificates are
                                            subordinate to the notes.
 
                                            The residual interest certificates are not being offered through this
                                            prospectus supplement or the accompanying prospectus.
 
ASSETS OF THE ISSUER
 
  Loans...................................  The assets of the issuer will consist primarily of a pool of mortgage
                                            loans, which will have an aggregate principal balance of
                                            approximately $418,342,161 as of March 1, 1999. The loans will be
                                            secured by first liens on one- to four-unit single family residences,
                                            condominium units and townhouses.
 
                                            Approximately 9.20% of the loans, by Cut-Off Date aggregate principal
                                            balance, will bear interest at a fixed rate for the term of the loan.
                                            Approximately 90.80% of the loans, by original aggregate principal
                                            balance, will bear interest at an adjustable rate.
 
                                            The interest rate on each adjustable-rate loan will be subject to
                                            adjustment after an initial period. Approximately 63.57% of the
                                            loans, by Cut-Off Date principal balance, known as "2/28 loans" will
                                            bear interest at a fixed rate for approximately two years after
                                            origination. Approximately 19.67% of the loans, by Cut-Off Date
                                            aggregate principal balance, known as "3/27 loans" will bear interest
                                            at a fixed rate for three years after origination. Approximately
                                            7.55% of the loans, by Cut-Off Date aggregate principal balance, will
                                            bear interest at a fixed rate for six months after origination. At
                                            the end of the six month, two year or three year period and every six
                                            months after that date, each of these adjustable-rate loans will be
                                            subject to an interest rate adjustment.
 
                                            The loans have been originated using underwriting standards that are
                                            less stringent than FHLMC or FNMA guidelines concerning first-lien
                                            mortgage loans. See "The Pool" in this prospectus supplement and "The
                                            Trust Funds--Residential Loans" in the accompanying prospectus.
 
SERVICING OF THE LOANS....................  Fairbanks, as the servicer, will perform the loan servicing and
                                            receive a monthly servicing fee and other servicing compensation. The
                                            servicer also will make reasonable and customary expense advances
                                            with respect to the loans, in accordance with reasonable and
                                            customary servicing procedures. See "Description of the Transfer and
                                            Servicing Agreements--Servicing" in this prospectus supplement.
 
                                            Fremont Investment & Loan will be the master servicer. The master
                                            servicer will advance certain delinquent payments of interest and
                                            principal on the loans, will pay compensating interest to cover
                                            prepayment interest shortfalls to the extent described in this
                                            prospectus supplement, will monitor the servicing activities of the
                                            servicer and will be available to assume the servicing upon a
                                            termination of the servicer. See "Master Servicer" in this prospectus

                                            Fairbanks has agreed to service the loans beginning on or before
                                            May 1, 1999. The master servicer will service the loans for an
                                            interim period beginning on the closing date until Fairbanks has
                                            assumed its duties as servicer.

CREDIT ENHANCEMENT........................  Credit enhancement for the notes will be provided by and utilized in
                                            the following order of priority:

                                            o  first, the subordination of the residual interest certificates;

                                            o  second, the overcollateralization that results from the cash flow
                                               structure; and

                                            o  third, the Guaranty Policy as described below.

                                            Each of these sources of credit enhancement is intended to increase
                                            the likelihood that you will receive the full and timely amount of
                                            interest payments and full amount of principal payments due on the
                                            notes and to provide protection against losses on the loans. The
                                            credit enhancement for the notes is for the benefit of the Series
                                            1999-1 notes only and the Series 1999-1 notes will not be entitled to
                                            the benefits of any other credit enhancement. See "Risk Factors--
                                            Adequacy of Credit Enhancement" in this prospectus supplement.

  Subordination...........................  The rights of the holders of the residual interest certificates to
                                            receive payments from any remaining amounts available on each payment
                                            date are subordinate to your rights. See "Description of
                                            Credit Enhancement--Subordination" in this prospectus supplement.

  Overcollateralization; Application of
     Excess Spread........................  The "Overcollateralization Amount" with respect to any payment date,
                                            will equal the excess of the aggregate principal balance of the loans
                                            over the unpaid principal balance of the notes, after giving effect
                                            to regular principal and interest payments on the notes on such
                                            payment date. On the closing date, the Overcollateralization Amount
                                            will be equal to $0. The Overcollaterization Amount is expected to
                                            increase through the application of Excess Spread to reduce the
                                            unpaid principal balance of the notes. This application of Excess
                                            Spread is intended to create and maintain the Overcollateralization
                                            Amount at a level equal to a certain target amount.

                                            The overcollateralization target amount may increase or decrease over
                                            time, subject to certain minimum and maximum amounts and trigger
                                            events that are based on excess spread requirements and the
                                            delinquency and loss experience of the loans and the outstanding
                                            principal balance of the loans. See "Description of Credit
                                            Enhancement--Overcollateralization" in this prospectus supplement.
  
                                            An increase in the overcollateralization target amount will occur
                                            if, among other things, the delinquency or loss experience of the
                                            loans exceeds certain levels established by the Securities Insurer.
                                            These levels can be changed by the Securities Insurer. If an increase
                                            in the overcollateralization target amount occurs, then the
                                            principal amortization of the notes would be accelerated
                                            by the payment of any available Excess Spread to the notes,
                                            until the Overcollateralization Amount equals the increased
                                            overcollateralization target amount.

                                            If the delinquency or loss experience of the loans does not exceed
                                            the levels established by the Securities Insurer, then a decrease or

                                            stepdown in the overcollateralization target amount may initially
                                            occur when the outstanding principal balance of the loans is reduced
                                            to an amount established by the Securities Insurer. A decrease or
                                            stepdown will likely result in the current Overcollateralization
                                            Amount exceeding the decreased overcollateralization target amount.
                                            If the Overcollateralization Amount exceeds the overcollateralization
                                            target amount, then (i) all or a portion of the principal payments
                                            that would otherwise be paid to the notes will instead be paid to the
                                            residual interest certificates and (ii) the principal amortization
                                            of the notes would be reduced in relation to the principal
                                            amortization of the loans. The Securities Insurer may lower the
                                            overcollateralization target amount at any time to certain minimum
                                            amounts.

  Guaranty Policy.........................  A financial guaranty insurance policy (the "Guaranty Policy") from
                                            Financial Security Assurance Inc., a New York corporation (the
                                            "Securities Insurer"), will irrevocably and unconditionally guaranty
                                            to the indenture trustee timely payment of interest and ultimate
                                            payment of principal due on the notes. The Guaranty Policy may not be
                                            canceled for any reason. The Guaranty Policy does not guaranty any
                                            specified rate of prepayments or any interest payments carried
                                            forward to subsequent payment dates due to the Net Funds Cap, nor
                                            does the Guaranty Policy provide funds to redeem any of the notes,
                                            unless such redemption is at the option of the Securities Insurer.

ALLOCATION AND PAYMENTS TO
  THE NOTES...............................  Interest and principal payments due on the notes will be paid from
                                            the Available Payment Amount and any Insured Payment made under the
                                            Guaranty Policy. On each payment date, the priority of payments from
                                            the Available Payment Amount will be as follows:
 
                                            o  first, to pay the Regular Payment Amount; and

                                            o  second, to pay the Excess Spread, if any.

                                            The "Available Payment Amount" with respect to any payment date, will
                                            generally equal the sum of interest and scheduled principal payments
                                            collected from the loans during the related Due Period or advanced by
                                            the master servicer and any prepayments or other unscheduled
                                            principal payments collected during the related Due Period, minus the
                                            payment of the issuer's fees and expenses including the fees owed to
                                            the master servicer, the servicer, the Securities Insurer and the
                                            indenture trustee.
 
                                            The Securities Insurer will be required to make an Insured Payment to
                                            the indenture trustee upon receipt of a claim under the Guaranty
                                            Policy. See "Description of Credit Enhancement--Financial Guaranty

                                            An "Insured Payment" with respect to any payment date, generally will
                                            be made under the Guaranty Policy to cover any deficiency
                                            attributable to the sum of (i) any deficiency resulting from the
                                            Available Payment Amount being less than the accrued and unpaid
                                            interest due on the notes and (ii) any deficiency resulting from the
                                            aggregate unpaid principal balances of the loans being less than the
                                            aggregate unpaid principal balances of the notes. Insured Payments
                                            will not be available to cover interest shortfalls on the Notes
                                            resulting from the Relief Act or interest payments carried forward
                                            from prior payment dates due to the application of the Net Funds Cap.

                                            The "Regular Payment Amount" with respect to any payment date, will
                                            generally equal the lesser of:

                                            o  the Available Payment Amount; and

                                            o  the sum of the following amounts:

                                               o  the accrued and unpaid interest due on the notes for the related
                                                  Accrual Period; and

                                               o  the amount of principal collected on the loans, but not in excess
                                                  of the amount sufficient for the overcollateralization amount to
                                               reach or maintain the target overcollateralization amount.

                                            The "Excess Spread" with respect to any payment date, will equal the
                                            excess, if any, of the Available Payment Amount, over the Regular
                                            Payment Amount.

                                            See "Description of the Notes" in this prospectus supplement for a
                                            further discussion of the payments of interest and principal on the
                                            notes.

  Application of the Regular Payment
     Amount...............................  The Regular Payment Amount and any Insured Payment will be paid on

                                            o  first, to pay the holders of the notes accrued and unpaid
                                               interest;

                                            o  second, to pay to the holders of the notes principal in an amount
                                               equal to scheduled principal amounts collected on the loans during
                                               the preceding Due Period, and any principal prepayments or other
                                               unscheduled principal payments collected during such Due Period,
                                               subject to certain adjustments resulting from the notes being
                                               either overcollateralized or undercollateralized in certain
                                               circumstances, until the notes have been paid their principal
                                               balance in full; and

                                            o  third, any remaining amount to be applied together with Excess
                                               Spread for payment as specified in "--Application of Excess
                                               Spread" below.

                                            See "Description of the Notes" in this prospectus supplement.

  Application of Excess Spread............  The Excess Spread, if any, will be paid on each payment date in the
                                            following order of priority (after giving effect to all payments
                                            specified above under "--Application of the Regular Payment Amount"):

                                            o  first, to pay the Securities Insurer in the amount that is needed
                                               to reimburse the Securities Insurer for any Insured Payments

                                               to the holders of the residual interest certificates.
 
                                            The "Overcollateralization Deficiency Amount" with respect
                                            to any payment date, will equal the excess, if any, of the

                                            Amount.

OPTIONAL REDEMPTION.......................  The holders of residual interest certificates have the option to
                                            cause the issuer to effect an early redemption of the notes on or
                                            after any payment date on which the outstanding aggregate principal
                                            balance of the loans declines to 10% or less of the aggregate
                                            principal balance of the loans as of the Cut-Off Date (the first such
                                            payment date, the "Call Option Date"), by purchasing all of the loans
                                            at a price that will at least pay in full accrued interest, interest
                                            carried forward due to the Net Funds Cap, together with accrued
                                            interest thereon, unreimbursed servicing advances and monthly
                                            advances and principal of the notes. On or after any payment date on
                                            which the outstanding aggregate principal balance of the loans
                                            declines to 5% or less of the aggregate principal balance of the
                                            loans as of the Cut-Off Date, the Securities Insurer or the servicer
                                            will have the option to cause the issuer to effect the same early
                                            redemption of the notes if the holders of the residual interest
                                            certificates fail to exercise this early redemption option.
 
                                            In addition, whether or not the Call Option Date has occurred, if
                                            certain events of default occur with respect to the issuer, the
                                            Securities Insurer may, at its option, cause an early redemption of
                                            the notes. See "Description of the Notes--Optional Redemption" in
                                            this prospectus supplement.

TAX STATUS................................  Special counsel to the depositor and the underwriters is of the
                                            opinion that under existing law the notes will be characterized as
                                            debt for federal income tax purposes and that the issuer will not be
                                            characterized as an association or a publicly traded partnership
                                            taxable as a corporation or a taxable mortgage pool for federal
                                            income tax purposes.

                                            By acceptance of a note, you are deemed to agree to treat your notes
                                            as debt for Federal, state and local income tax purposes and
                                            franchise tax purposes. See "Federal Income Tax Consequences" in this
                                            prospectus supplement and "Certain Federal Income Tax Consequences"
                                            in the accompanying prospectus for additional information concerning

                                            supplement and in the accompanying prospectus, the notes are eligible
                                            for purchase by persons investing assets of employee benefit plans or
                                            individual retirement accounts. You should carefully review with your
                                            legal advisors whether the purchase or holding of the notes could
                                            give rise to a prohibited transaction. See "ERISA Considerations" in
                                            this prospectus supplement and in the accompanying prospectus.

LEGAL INVESTMENT..........................  Your notes will constitute "mortgage related securities" for purposes
                                            of the Secondary Mortgage Market Enhancement Act of 1984, as amended
                                            ("SMMEA") for as long as they are rated not lower than the second
                                            highest rating category by one or more nationally recognized
                                            statistical rating organizations and, as such, will be legal
                                            investments for certain entities to the extent provided in SMMEA and
                                            applicable state laws. You should consult your own legal advisors to
                                            determine whether the notes constitute legal investments for you. See
                                            "Legal Investment Matters" in this prospectus supplement and "Legal
                                            Investment" in the accompanying prospectus.

NOTE RATINGS..............................  On the closing date, the notes are required to be rated "Aaa" by
                                            Moody's Investors Service, Inc. and "AAA" by Standard & Poor's
                                            Ratings Services, a division of The McGraw-Hill Companies, Inc. (the
                                            "Rating Agencies"). See "Ratings" in this prospectus supplement and
                                            "Rating" in the accompanying prospectus for a discussion of the
                                            primary factors upon which the ratings are based.

IMPORTANT COVENANTS OF NOTEHOLDERS .......  By accepting your note, you agree not to institute or join in any
                                            bankruptcy, reorganization or other insolvency or similar proceeding
                                            against the transferor, the servicer, the master servicer or the
                                            issuer. You also agree to allow the Securities Insurer to exercise
                                            all of your voting rights with respect to your notes. See "Risk
                                            Factors--Limitations on Rights of Noteholders" and "Description of

                                  RISK FACTORS
 
     You should carefully consider the following risks before making an
investment decision. In particular, payments on your notes will depend on
payments received on and other recoveries with respect to the loans.
 
     Therefore, you should carefully consider the risk factors relating to the
loans. The risks and uncertainties described below are not the only ones
relating to your notes. Additional risks and uncertainties not presently known
to Fremont Investment & Loan or PaineWebber Mortgage Acceptance Corporation IV,
or that they currently consider immaterial may also impair your investment.
 
     If any of the following risks are realized, your investment could be
materially and adversely affected.
 
     This prospectus supplement also contains forward-looking statements that
involve risks and uncertainties. Actual results could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors, including the risks described below and elsewhere in this prospectus
supplement.
 
YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS
 
     BASIS RISK. The yield on your notes will be sensitive to fluctuations in
the level of One-Month LIBOR and may be adversely affected by the application of
the Net Funds Cap. The prepayment of the mortgage loans with higher mortgage
rates may result in a lower Net Funds Cap. If on any payment date the
application of the Net Funds Cap results in an interest payment lower than the
interest rate on the notes during the related Accrual Period, the value of your
notes may decline.
 
     The mortgage pool will contain adjustable-rate mortgage loans that, after a
period of six months, two years or three years following the date of
origination, adjust semi-annually based upon the London interbank offered rate
for six-month United States dollar deposits (the "Six-Month LIBOR").
Consequently, the interest due on such mortgage loans during any Due Period may
not equal the amount of interest that would accrue at One-Month LIBOR plus the
applicable margin on your notes during the related Accrual Period. In
particular, because the interest rate on your notes adjusts monthly, while the
interest rates on the mortgage loans adjust semi-annually, and in some cases,
only after the expiration of the related fixed-rate period, or with respect to
fixed-rate loans, not at all, subject to any applicable periodic cap, maximum
mortgage rate and minimum mortgage rate, in a rising interest rate environment,
the amount of interest paid on the notes on any payment date may be less than
One-Month LIBOR plus the applicable margin.
 
     Although you will be entitled to receive on subsequent payment dates the
amount of any interest shortfall resulting from the application of the Net Funds
Cap on the notes, in light of the payment priorities on such payment dates,
there is no assurance that funds will be available. The failure to pay such
amount carried forward on subsequent payment dates due to a lack of funds will
not be an event of default under the indenture. In addition, the Guaranty Policy
does not cover, and the ratings of the notes do not address, the likelihood of
the payment of such amounts carried forward.
 
     The yield to maturity on the notes may be affected by the resetting of the
mortgage rates on the adjustable-rate mortgage loans. In addition, because the
mortgage rate for most mortgage loans is based on Six-Month LIBOR plus the
related margin, such rate could be higher than prevailing market interest rates,
which may result in an increase in the rate of prepayments on the mortgage loans
after the adjustment. Also, while a substantial majority of the "2/28" and
"3/27" loans impose prepayment penalties if a loan is prepaid during the initial
one to five years of the loan, these penalties are typically suspended during
the sixty-day period following the initial adjustment date. The suspension of
the prepayment penalties may also result in increased prepayments on the
mortgage loans during such sixty-day period.
 
     See "Certain Legal Aspects of Residential Loans--Prepayment Charges and
Prepayments" in the prospectus.
 
     VARIATIONS IN YIELD TO MATURITY. The degree to which the actual yield of
your notes may vary from the anticipated yield will depend upon:
 
     o the price of your notes, including the amount of any premium or discount;
 
                                      S-12
<PAGE>
     o the degree to which the timing of payments on your notes is sensitive to
       the prepayment experience of loans and the application of Excess Spread
       as principal on the notes;
 
     o the timing of delinquencies, defaults and losses on the loans to the
       extent not covered by the credit enhancement, including the Guaranty
       Policy; and
 
     o a change in the overcollateralization target amount or a change in the
       delinquency or loss levels with respect to the loans or excess spread
       requirements used to determine an increase or decrease in the
       overcollateralization target amount.
 
The allocation of Excess Spread as an additional payment of principal on the
notes until the Overcollateralization Amount equals the overcollateralization
target amount will accelerate the principal amortization of the notes relative
to the speed at which principal is paid on the loans. However, any reduction in
the Overcollateralization Amount will slow the principal amortization of the
notes. See "Prepayment and Yield Considerations" in this prospectus supplement.
 
     PREPAYMENT EXPERIENCE OF THE LOANS. The rate and timing of payments of
principal on the loans, among other factors, will affect the rates of principal
payments on the notes and the aggregate amount of payments and the yield to
maturity of your notes. Because the prepayment experience of the loans will
depend on future events and a variety of factors, the prepayment experience of
the loans is uncertain and in all likelihood will not conform to any projected
rates of prepayments. See "Prepayment and Yield Considerations" in this
prospectus supplement.
 
LIMITED LIQUIDITY
 
     A secondary market for the notes may not develop or, if it does develop, it
may not provide you with liquidity of investment or continue while your notes
are outstanding. See "Risk Factors--Limited Liquidity" in the accompanying
prospectus.
 
ADEQUACY OF CREDIT ENHANCEMENT
 
     RATINGS OF SECURITIES INSURER. Any reduction in a rating assigned to the
claims-paying ability of the Securities Insurer may result in a reduction in the
rating of the notes. Future events may reduce the rating of the Securities
Insurer or impair the ability of the Securities Insurer to pay claims for
Insured Payments under the Guaranty Policy. In that event, the Securities
Insurer might not have the ability to cover delays or shortfalls in payments of
interest or ultimate principal due on the notes. See "Description of Credit
Enhancement--Financial Guaranty Insurance Policy" in this prospectus supplement.
 
     LOAN DELINQUENCIES, DEFAULTS AND LOSSES. Delinquencies, if not advanced by
the master servicer, defaults and losses on the loans will reduce the credit
enhancement available from the overcollateralization feature. If amounts
available from this credit enhancement are not adequate to protect against the
delinquencies, defaults and losses experienced on the loans, then delays or
shortfalls in payments of interest or principal due on the notes will occur,
unless such delays or shortfalls are covered under the Guaranty Policy. See
"Description of Credit Enhancement" in this prospectus supplement.
 
     AVAILABILITY OF EXCESS SPREAD FOR OVERCOLLATERALIZATION. Excess Spread may
not be generated in sufficient amounts to create and maintain the
Overcollateralization Amount at the overcollateralization target amount at all
times. In particular, delinquencies, if not advanced by the master servicer,
defaults and principal prepayments on the loans will reduce the Excess Spread
that otherwise would be available on a payment date. The reduction of the
available Excess Spread will result in a slower principal amortization of the
notes in relation to the loans, which in turn will result in a lower level of
Overcollateralization Amount. See "Description of Credit
Enhancement--Overcollateralization" in this prospectus supplement.
 
     LIMITATIONS ON SUBORDINATION. The holders of the Residual Interest
Certificates are never obligated to refund payments previously distributed to
them to holders of the notes, including payments of Excess Spread, even if on a
subsequent payment date insufficient funds are available to pay interest or
principal due on the notes. See "Description of Credit
Enhancement--Subordination" in this prospectus supplement.
 
                                      S-13
<PAGE>
LIMITATIONS ON RIGHTS OF NOTEHOLDERS
 
     Generally, the Securities Insurer may exercise all of your voting rights
with respect to your notes (the "Noteholder Rights") without your consent. The
exercise, or a refusal to consent to the exercise, by the Securities Insurer of
certain Noteholder Rights could be adverse to your interest. For example, such
an event could cause an unanticipated prepayment of principal on your notes. See
"Description of the Transfer and Servicing Agreements--Restrictions on
Noteholder Rights" in this prospectus supplement.
 
UNDERWRITING GUIDELINES
 
     The originator's underwriting standards are intended to assess the
creditworthiness of the borrower and the value of the mortgaged property and to
evaluate the adequacy of such property as collateral for the loan. In comparison
to first lien mortgage loans that conform to the underwriting guidelines of FNMA
or FHLMC the loans have generally been underwritten or reunderwritten with more
lenient underwriting criteria. For example, the loans may have been made to
borrowers having imperfect credit histories, ranging from minor delinquencies to
bankruptcies, or borrowers with higher ratios of monthly mortgage payments to
income or higher ratios of total monthly credit payments to income. Accordingly,
the loans will likely experience higher, and possibly substantially higher,
rates of delinquencies, defaults and losses than the rates experienced by loans
underwritten according to FNMA or FHLMC guidelines. Furthermore, changes in the
values of the mortgaged properties may have a greater effect on the delinquency,
foreclosure, bankruptcy and loss experience of the loans than on mortgage loans
originated according to FNMA or FHLMC guidelines. No assurance can be given that
the values of the mortgaged properties have remained or will remain at the
levels in effect on the dates of origination of the related loans. See
"--Adequacy of Credit Enhancement" above, and "Underwriting Criteria" in this
prospectus supplement.
 
SERVICING RISK
 
     The servicing of loans such as those originated pursuant to the
underwriting guidelines described above (as compared to the servicing of prime
mortgage loans) requires special skill and diligence. The servicing of these
types of loans generally requires more attention to each account, earlier and
more frequent contact with borrowers in default and commencing the foreclosure
process at an earlier stage of default. The loans are not currently being
serviced by the servicer. On or before May 1, 1999, the servicing of such loans
will be transferred from Fremont to Fairbanks. Following such time, Fairbanks
will directly service all of the loans. Interruptions in servicing may occur
during the transfer of servicing to the servicer.
 
     Pursuant to the servicing agreement, the term of the servicer shall be
extendable for successive 90 day terms until the notes are paid in full,
provided that prior to the expiration of each term the Securities Insurer
delivers written notice of renewal to the servicer. In the event that such
renewal notice is not delivered and a successor servicer is appointed, the
servicing of the loans will be transferred. During such period, interruptions in
servicing may occur potentially resulting in the loans suffering a higher
default rate.
 
REALIZATION UPON DEFAULTED LOANS
 
     ADEQUACY OF SECURITY AND SEVERITY OF LOSSES. Assuming that the mortgaged
properties provide adequate security for the loans, substantial delays in
recoveries may occur from the foreclosure or liquidation of defaulted loans. No
assurance can be given that the values of the mortgaged properties have remained
or will remain at the levels in effect on the dates of origination of the
related loans. Further, liquidation expenses (such as legal fees, real estate
taxes, and maintenance and preservation expenses) will reduce the proceeds
payable on the mortgage notes and thereby reduce the security for the loans. In
the event any of the mortgaged properties fail to provide adequate security for
the related loan, you may experience a loss if the Securities Insurer were
unable to perform its obligations under the Guaranty Policy. See "Description of
the Transfer and Servicing Agreements--Realization Upon Defaulted Loans" in this
prospectus supplement, and "Certain Legal Aspects of Residential Mortgage
Loans--Foreclosure on Mortgages" in the prospectus.
 
     APPLICATION OF BANKRUPTCY LAWS. The application of federal and state laws,
including bankruptcy and debtor relief laws, may interfere with or adversely
affect the ability to realize upon the mortgaged properties, enforce deficiency
judgments or pursue collection litigation with respect to defaulted loans. As a
consequence,
 
                                      S-14
<PAGE>
borrowers who have defaulted on their loans and sought, or are considering
seeking, relief under bankruptcy or debtor relief laws will have substantially
less incentive to repay their loans, and such loans will likely experience more
severe losses, which may be total losses. See "--Adequacy of Credit Enhancement"
above and "--Legal Considerations--Legal Compliance and Regulation" below.
 
GEOGRAPHIC CONCENTRATION
 
     CALIFORNIA CONCENTRATION. Because of the geographic concentration of
mortgaged properties within California, an economic downturn or recession in
California may affect the ability of the borrowers to timely pay their loans,
and accordingly the loans may experience higher rates of delinquencies, defaults
and losses than the rates experienced by loans having greater geographical
diversification. In addition, mortgaged properties located in California may
experience special hazards that are not covered by any available casualty
insurance, including earthquakes, mudslides and other disasters. Accordingly,
these loans may experience higher rates of delinquencies, defaults and losses
than rates experienced for similar loans secured by residential properties
located in other states. See "--Adequacy of Credit Enhancement" above.
 
NON-RECORDATION OF ASSIGNMENTS
 
     The transferor will not be required to record assignments of the mortgages
to the indenture trustee in the real property records of California and certain
other states. The master servicer will retain record title to such mortgages on
behalf of the issuer, the indenture trustee and the holders of the notes. See
"Description of the Transfer and Servicing Agreements--Sale and Assignment of
the Loans" in this prospectus supplement.
 
     The recordation of the assignments of the mortgages in favor of the
indenture trustee is not necessary to effect a pledge of the loans to the
indenture trustee. However, if the transferor or the depositor were to sell,
assign, satisfy or discharge any loan prior to recording the related assignment
in favor of the indenture trustee, the other parties to such sale, assignment,
satisfaction or discharge may have rights superior to those of the indenture
trustee. In some states, in the absence of such recordation of the assignments
of the mortgages, the pledge to the indenture trustee of the loans may not be
effective against certain creditors or purchasers from the transferor or a
trustee in bankruptcy of the transferor. If such other parties, creditors or
purchasers have rights to the loans that are superior to those of the indenture
trustee, you could lose the right to future payments of principal and interest
from such loans and could suffer a loss of principal and interest to the extent
that such loss is not otherwise covered by the applicable credit enhancement.
 
LEGAL CONSIDERATIONS
 
     INSOLVENCY OF TRANSFEROR. If the FDIC is appointed receiver or conservator
of the transferor, the FDIC's administrative expenses may have priority over the
interest of the issuer and/or the indenture trustee in the loans. In addition,
the Federal Deposit Insurance Act, as amended by the Financial Institutions
Reform, Recovery and Enforcement Act of 1989, gives the FDIC certain powers in
its capacity as a receiver or conservator of the transferor that if exercised
could result in delays or reductions in payments of principal and interest on
the notes, unless such payments are covered under the Guaranty Policy.
 
     Salient among the FDIC's powers as receiver or conservator is the power to
disaffirm or repudiate any of the transferor's contracts or leases the
performance of which would be burdensome and the disaffirmance or repudiation of
which would promote the orderly administration of the transferor's affairs. It
is unclear whether the FDIC can utilize this power to repudiate the transfer of
the loans to the depositor and administer the loans as part of any receivership
or conservatorship of the transferor. Any attempt by the FDIC to repudiate the
transfer of the loans to the depositor in a receivership or conservatorship of
the transferor, even if unsuccessful, could result in delays or reductions in
payments of principal and interest on the notes, unless such payments are
covered under the Guaranty Policy.
 
     The FDIC recently proposed a statement of policy outlining the
circumstances under which the FDIC will not seek to repudiate transfers made as
part of a securitization, such as the transfer of the loans to the depositor.
Although that statement of policy is not yet final, much of it merely reiterates
pre-existing law, and substantive changes are not expected. The transfer of the
loans to PaineWebber Mortgage Acceptance Corporation IV has been structured with
the specific intent to satisfy the requirements of the proposed statement of
policy.
 
                                      S-15
<PAGE>
     See "Description of the Transfer and Servicing Agreements--Sale and
Assignment of the Loans" in this prospectus supplement.
 
     BANKRUPTCY OF OTHER PARTIES. The depositor intends to treat the transfer of
the loans to the issuer as an absolute transfer and not as a secured lending
arrangement. In such event, the loans would not be part of the depositor's
bankruptcy estate in the event of its bankruptcy and would not be available to
the depositor's creditors. 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. This position, if accepted by a court, could
prevent timely payments of amounts due on the notes and result in a reduction of
payments on the notes.
 
     In the event a bankruptcy or insolvency of the master servicer or servicer,
the bankruptcy trustee or receiver may have the power to prevent the Securities
Insurer, the indenture trustee or the issuer from appointing a successor master
servicer or servicer.
 
     In the event of the insolvency of the servicer, if cash collections are
commingled with such person's own funds for at least ten days, the issuer 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 such
person may result in delays in payment and failure to pay amounts due on the
notes.
 
     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. See "Certain Legal Aspects of Residential Loans" in the prospectus.
 
     LEGAL COMPLIANCE AND REGULATION. Federal and state laws regulate the
underwriting, origination, servicing and collection of the loans. These laws
will likely change over time and may become more restrictive or stringent with
respect to certain of these activities of the servicer, master servicer and
transferor. Violations of these Federal and state laws may limit the ability of
the servicer or master servicer to collect principal or interest on the loans,
may entitle the borrowers to a refund of amounts previously paid, and may
subject the issuer, the servicer, master servicer or transferor to damages and
administrative sanctions. The inability to collect principal or interest on the
loans because of violations of federal or state laws will likely cause the loans
to experience higher rates of delinquencies, defaults and losses. An assessment
of damages or sanctions against the issuer could result in the issuer's assets
being insufficient to pay all interest and principal due on the notes, and
against the servicer, master servicer or the transferor may adversely affect the
ability of the servicer or master servicer to service the loans or the
transferor to repurchase or replace defective loans. See "Risk Factors--Certain
Other Legal Considerations Regarding Residential Loans" in the prospectus. The
transferor will be required to repurchase or replace any loan that did not
materially comply with applicable Federal and state laws. See "--Limitations on
the Transferor and Servicer" below.
 
     POTENTIAL LAWSUITS AGAINST THE TRANSFEROR. Because the nature of the
transferor's business involves the collection of numerous accounts, the validity
of liens and compliance with state and Federal lending laws, the transferor is
subject to numerous claims and legal actions in the ordinary course of its
business. Several class-action lawsuits have been filed against a number of
consumer finance companies alleging that the compensation of mortgage brokers
through the payment of yield spread premiums violates various Federal and state
consumer protection laws. While the transferor is not a party to any suit of
this nature, lawsuits could be filed against the transferor in the future, and
the results of any such lawsuits are uncertain.
 
LIMITATIONS ON THE TRANSFEROR AND SERVICER
 
     DEPENDENCE ON SERVICER. The amount and timing of payments on the notes
generally will be dependent upon Fairbanks Capital Corp. as the servicer to
perform its servicing obligations in an adequate and timely manner. See
"Servicer--Servicing Procedures" in this prospectus supplement. The failure of
the Securities Insurer to renew the term of the servicer every ninety days or
the occurrence of certain events of default may result in the termination of the
servicer. For example, an event that causes a material adverse effect, may
result in the termination of the servicer. See "Description of the Transfer and
Servicing Agreements--Servicer Determinations and Events of Default" in this
prospectus supplement. The master servicer or such other successor appointed by
the Master Servicer and approved by the Securities Insurer will assume the loan
servicing
 
                                      S-16
<PAGE>
functions upon a termination of the servicer. Such termination with its transfer
of daily collection activities will likely increase the rates of delinquencies,
defaults and losses on the loans.
 
     ABILITY TO REPURCHASE OR REPLACE DEFECTIVE LOANS. If the transferor fails
to cure a material breach of its loan representations and warranties with
respect to any loan in a timely manner, then the transferor is required to
repurchase or replace such defective loan. See "Description of the Transfer and
Servicing Agreements--Representations and Warranties" in this prospectus
supplement. The transferor may not be capable of repurchasing or replacing any
defective loans, for financial or other reasons. The transferor's inability to
repurchase or replace defective loans would likely cause the loans to experience
higher rates of delinquencies, defaults and losses. See "--Adequacy of Credit
Enhancement" above, and "Fremont Investment & Loan" and "Description of Credit
Enhancement" in this prospectus supplement.
 
     RISKS ASSOCIATED WITH YEAR 2000 COMPLIANCE. The transferor and the
depositor are aware of the issues associated with the programming code in
existing computer systems as the year 2000 approaches. The "year 2000 problem"
is pervasive and complex; substantially all computer operations will be affected
in some way by the rollover of the two-digit year value to 00. The issue is
whether the computer systems will properly recognize date-sensitive information
when the year changes to 2000. Systems that do not properly recognize such
information could generate erroneous data or cause a system to fail.
 
     The master servicer, the servicer and the indenture trustee will certify
that they are committed either to implement modifications to their respective
existing systems to the extent required to cause them to be year 2000 ready or
acquire computer systems that are year 2000 ready, in each case prior to
January 1, 2000. However, the depositor has not made any independent
investigation of the computer systems of the master servicer, the servicer or
the indenture trustee. In the event that computer problems arise out of a
failure of such efforts to be completed on time, or in the event that the
computer systems of the master servicer, the servicer or the indenture trustee
are not fully year 2000 ready, the resulting disruptions in the collection or
distribution of receipts on the loans could materially and adversely affect your
investment.
 
     With respect to the year 2000 problem, DTC has informed members of the
financial community that it has developed and is implementing a program so that
its systems, as they relate to the timely payment of distributions, including
principal and interest payments, to security holders, book-entry deliveries, and
settlement of trades within DTC, continue to function appropriately on and after
January 1, 2000. This program includes a technical assessment and a remediation
plan, each of which is complete. Additionally, DTC's plan includes a testing
phase, which is expected to be completed within appropriate time frames.
 
     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to, its participating
organizations, through which you will hold your notes, as well as the computer
systems of third party service providers. DTC has informed the financial
community that it is contacting and will continue to contact third party vendors
from whom DTC acquires services to:
 
     o impress upon them the importance of such services being year 2000
       compliant; and
 
     o determine the extent of their efforts for year 2000 remediation, and, as
       appropriate, testing, of their services.
 
In addition, DTC has stated that it is in the process of developing such
contingency plans as it deems appropriate.
 
     If problems associated with the year 2000 problem were to occur with
respect to DTC and the services described above, payments to you could be
delayed or otherwise adversely affected.

                                    THE POOL
 
GENERAL
 
     On or about March 23, 1999 (the "Closing Date"), the Depositor will acquire
from the Transferor a pool (the "Pool") of loans (the "Loans") having an
aggregate unpaid principal balance as of the close of business on March 1, 1999
(the "Cut-Off Date"), of approximately $418,342,161 (the "Cut-Off Date Pool
Principal Balance"). The Depositor will then transfer the Loans to the Issuer
pursuant to the Owner Trust Agreement in exchange for the Notes and the Residual
Interest Certificates. The Owner Trust will be entitled to all payments of
principal and interest in respect of the Loans due after the Cut-Off Date. The
Loans will be secured by first lien mortgages, deeds of trust and security deeds
of trust and security deeds on residences (the "Mortgaged Properties").
 
     Approximately 90.80% of the Loans, by Cut-Off Date Pool Principal Balance,
will be closed-end, fully amortizing, adjustable-rate home loans (the
"Adjustable-Rate Loans"), and approximately 9.20% of the Loans will be fully
amortizing fixed-rate home loans (the "Fixed-Rate Loans") none of which are
insured or guaranteed by any governmental agency. The Loans have been originated
for the purpose of purchasing, and refinancing single-family residences,
consolidating debt, financing property improvements, providing cash to the
borrower for unspecified purposes or a combination of the foregoing. The
majority of the Loans will have been originated or acquired by the Transferor on
a flow basis, through a network of small independent mortgage brokers ("broker
originations"), and a small number of the Loans were acquired by the Transferor
either through a network of correspondents or direct origination. No Loans were
purchased by the Transferor in bulk.
 
     The Loans have been underwritten in compliance with the underwriting
standards of the Transferor. See "Underwriting Criteria" in this prospectus
supplement.
 
PAYMENTS ON THE LOANS
 
     Interest on each Loan is payable monthly on its outstanding principal
balance at a per annum rate (the "Loan Rate"). The Loan Rate on each
Adjustable-Rate Loan will be subject to adjustment based on Six-Month LIBOR
after an initial period. Approximately 63.57% of the Loans, by Cut-Off Date Pool
Principal Balance, known as "2/28 loans" will bear interest at a fixed rate for
approximately two years after origination. Approximately 19.67% of the Loans, by
Cut-Off Date Pool Principal Balance, known as "3/27 loans" will bear interest at
a fixed rate for three years after origination. Approximately 7.55% of the
Loans, by Cut-Off Date Pool Principal Balance, will bear interest at a fixed
rate for six months after origination. Approximately 9.20% of the Loans, by
Cut-Off Date Pool Principal Balance, will bear interest at a fixed rate for the
life of the Loans.
 
     At the end of such six month, two year or three year period and at six
month intervals thereafter (each, a "Change Date"), the Loan Rate on each
Adjustable-Rate Loan will be adjusted to a rate equal to the sum of (1) the
London interbank offered rate for six-month United States dollar deposits
("Six-Month LIBOR"), as published in The Wall Street Journal, and (2) the number
of basis points stated in the mortgage note (the "Gross Margin"). The new Loan
Rate will be rounded and may be subject to Periodic Rate Caps, Lifetime Caps and
Lifetime Floors. A "Periodic Rate Cap" limits changes in the Loan Rate for each
Loan on a particular Change Date. The "Lifetime Cap" for a Loan is the maximum
Loan Rate that may be charged on a Loan, and the "Lifetime Floor" is the minimum
Loan Rate that may be charged on a Loan. The Loans do not provide for negative
amortization or limits on changes in monthly payments.
 
     Six-Month LIBOR.  Listed below are monthly Six-Month LIBOR rates on the
first business day of the related calendar month beginning in 1995, as published
by Bloomberg L.P. ("Bloomberg"). Such Six-Month LIBOR rates may fluctuate
significantly from month to month as well as over longer periods and may not
increase or decrease in a constant pattern. There can be no assurance that
levels of Six-Month LIBOR published in Bloomberg on a different LIBOR reference
date would have been at the same levels as those set forth below. The following
does not purport to be representative of future levels of Six-Month LIBOR (as
published by Bloomberg). No assurance can be given as to the level of Six-Month
LIBOR on any Change Date or during the life of any Loan based on Six-Month
LIBOR.

</TABLE>
 
     The initial Loan Rate in effect on an Adjustable-Rate Loan generally will
be lower, and may be significantly lower, than the Loan Rate that would have
been in effect based on the rate of Six-Month LIBOR and the Gross Margin at the
origination of the Loan. Therefore, unless Six-Month LIBOR declines after
origination of a Loan, the related Loan Rate will generally increase on the
first Change Date following origination of the Loan, subject to the Periodic
Rate Cap. The repayment of the Loans will be dependent on the ability of the
borrowers to make larger monthly payments following adjustments of the Loan
Rate. Loans that have the same initial Loan Rate at the Cut-Off Date may not
always bear interest at the same Loan Rate because the Loans may have different
Change Dates (and the Loan Rates therefore may reflect different levels of
Six-Month LIBOR), Gross Margins, Lifetime Caps and Lifetime Floors.
 
     The "Principal Balance" of a Loan on any day is equal to its unpaid
principal as of the Cut-Off Date after giving effect to scheduled principal
payments due on the Loan on or prior to the Cut-Off Date, whether or not
received, minus all principal reductions credited against the Principal Balance
of such Loan since the Cut-Off Date, including any principal losses recorded by
the Servicer on account of a short pay-off, short sale or other modification of
such Loan affecting the Principal Balance thereof; provided, however, that any
Liquidated Home Loan will have a Principal Balance of zero. With respect to any
date, the "Pool Principal Balance" will be equal to the aggregate Principal
Balances of all Loans as of such date.
 
     Although the Loans may be prepaid at any time, prepayment may subject the
borrower to a prepayment penalty, subject to state regulation. Generally,
approximately 84.99% of the Loans, by Cut-Off Date Pool Principal Balance,
provide for a prepayment penalty for certain partial prepayments and any
prepayments in full made during the first, second, third and fifth years of the
Loan, except for a short prepayment window at the time of the first adjustment
of the Loan Rate. The prepayment penalty would equal, generally, a certain
amount of advance interest on the amount of the prepayment of the Loan. Because
the Master Servicer is entitled to keep the prepayment penalties as additional
compensation, it will not be available to make payments on the Notes.
 
     The Loans will be serviced under an "actuarial interest" method in which
interest is charged to the related borrowers, and payments are due from such
borrowers as of a scheduled day each month that is fixed at the time of
origination. Payments received after a grace period following such scheduled day
are subject to a late charge. Each regular scheduled payment made by the
borrower is, therefore, treated as containing a predetermined amount of interest
and principal. Scheduled monthly payments made by the borrowers on the Loans
either earlier or later than their scheduled due dates will not affect the
amortization schedule or the relative application of such payments to principal
and interest. Interest accrued on each Loan will be calculated on the basis of a
360-day year consisting of twelve 30-day months.
 
     In connection with a partial prepayment, the Servicer, at the request of
the borrower, may recalculate the amortization schedule of the related Loan to
reduce the scheduled monthly payment over the remaining term to maturity.

CHARACTERISTICS OF THE LOANS
 
     Set forth below is certain statistical information regarding
characteristics of the Loans included in the Pool as of the Cut-Off Date. As of
the Cut-Off Date, the Loans had an approximate aggregate principal balance of
$418,342,161 (the "Cut-Off Date Pool Principal Balance"). Unless the context
indicates otherwise, any numerical or statistical information presented in this
prospectus supplement is based upon the characteristics of such pool of Loans
that will be included in the Owner Trust and that comprise the Cut-Off Date Pool
Principal Balance.
 
     Before the Closing Date, the Transferor may remove any of the Loans
identified as of the date of this prospectus supplement or may substitute
comparable loans for any of the Loans identified as of the date of this
prospectus supplement; provided, however, that the aggregate Principal Balance
of such Loans will not exceed 5% of the Cut-Off Date Pool Principal Balance. As
a result, the statistical information presented below regarding the
characteristics of the Loans included in the Pool may vary in certain respects
from comparable information based on the actual composition of the Loans
included in the Pool on the Closing Date. In addition, after the Cut-Off Date,
the characteristics of the actual Loans may materially vary from the information
below due to a number of factors, including prepayments after the Cut-Off Date
or the substitution or repurchase of Loans after the Closing Date.

                           FREMONT INVESTMENT & LOAN
 
GENERAL
 
     Fremont Investment & Loan, a thrift and loan organized as a California
industrial loan company ("Fremont" and, where applicable, the "Transferor"),
will sell the Loans to the Depositor pursuant to a Home Loan Purchase Agreement
(the "Home Loan Purchase Agreement") between the Depositor and the Transferor.
Fremont will be the master servicer of the Loans pursuant to the Sale and Master
Servicing Agreement (in such capacity, the "Master Servicer").
 
     Fremont was established in 1937 as a state chartered industrial loan
company and is currently engaged in the businesses of residential sub-prime real
estate lending, commercial real estate lending, insurance premium finance and
syndicated loan purchases. Fremont had total assets of approximately $2.5
billion as of December 31, 1998 and is regulated by both the FDIC and the
California Department of Financial Institutions. Fremont funds its loans
primarily through its 14 depository branches and has historically held its loans
in portfolio or participated in whole loan sale transactions. As of year-end
1998, Fremont had 804 employees.
 
     Fremont began originating sub-prime residential mortgage loans in
California in 1994 and currently originates loans through a national network of
mortgage brokers in approximately 30 states through five regional business
centers located in southern California (which contains two), northern
California, Illinois and Florida. Fremont's residential loan originations are
secured by one to four family residential properties, planned unit developments,
condominiums and townhomes. Fremont originates first mortgages to borrowers with
impaired or limited credit profiles. Fremont reunderwrites every loan prior to
funding and maintains strict quality control procedures to maintain the quality
of its originations at all locations. Fremont originated approximately
$1.0 billion in sub-prime residential mortgage loans in 1998.
 
     Fremont has its principal offices at 175 North Riverview Drive, Anaheim,
California 92808, and its telephone number is (714) 283-6500.

1998, 1997 and 1996 were $197 million, $159 million and $128 million,
respectively. Fremont General's business strategy includes achieving income
balance and geographic diversity among its business units in order to limit its
exposure to industry, market and regional concentrations. Fremont General's
common stock is traded on the New York Stock Exchange under the symbol "FMT."
 
     Fremont General's principal executive offices are located at 2020 Santa
Monica Boulevard, Santa Monica, California, 90404, and its telephone number is

                                MASTER SERVICER
 
MASTER SERVICER DUTIES
 
     Fremont, as Master Servicer, will be responsible for performing the loan
master servicing functions for the Loans pursuant to the Sale and Master
Servicing Agreement among the Issuer, the Master Servicer, the Transferor, the
Depositor and the Indenture Trustee (the "Sale and Master Servicing Agreement").
All references in the accompanying prospectus to "Master Servicer" shall mean
the "Servicer" with respect to this prospectus supplement. In consideration for
the performance of the master servicing functions for the Loans, the Master
Servicer is entitled to receive a monthly servicing fee (the "Master Servicer
Fee") as to each Loan in the amount equal to one-twelfth of the product of 0.15%
(the "Master Servicer Fee Rate") and the Principal Balance of such Loan as of
the first day of the immediately preceding Due Period (or as of the Cut-Off
Date, with respect to the first Due Period). In addition, the Master Servicer is
entitled to receive on a monthly basis additional compensation attributable to
investment earnings from amounts on deposit in the Collection Account, the Note
Payment Account, a portion of late payment charges, and prepayment penalties
which, together with the Master Servicer Fee, are referred to as the "Master
Servicer Compensation".
 
     The Master Servicer will service the Loans for an interim period beginning
on the Closing Date and ending on or before May 1, 1999. During this time the
Master Servicer shall be entitled to all Servicing Compensation,
 
                                      S-28
<PAGE>
and shall be vested with all of the rights and obligations of the Servicer. The
Master Servicer will transfer the servicing of the Loans to the Servicer on or
before May 1, 1999 and thereafter the Servicer will perform the servicing
functions with respect to the Loans.
 
     Under the Sale and Master Servicing Agreement, the Master Servicer will
perform the following master servicing functions:
 
          o The Master Servicer will advance delinquent payments of interest and
            principal on the Loans in order to maintain a regular flow of
            scheduled payments to holders of the Notes ("Noteholders"). Prior to
            each Payment Date, the Master Servicer will cause to be remitted an
            advance (a "Monthly Advance"), if necessary, to the Indenture
            Trustee for deposit into the Note Payment Account to be paid on the
            related Payment Date. The Monthly Advance will equal interest and
            principal due on the Loans (net of the Servicing Fee and Master
            Servicer Fee) during the related Due Period but delinquent. The
            Master Servicer may recover Monthly Advances, first from the
            borrower on whose behalf such Monthly Advance was made, then from
            subsequent collections on the related Loan. The Master Servicer is
            not required to make any Monthly Advance it deems not recoverable
            from subsequent collections on the related Loan;
 
          o If a Loan prepays in full or in part in any month other than on the
            date the related monthly payment was due, the borrower is only
            required to pay interest to the date of prepayment. In such event,
            the Master Servicer and the Servicer are obligated to pay any
            shortfall in interest ("Compensating Interest") up to an amount
            equal to the sum of the Master Servicer Fee and the Servicing Fee
            for such Payment Date. Such Compensating Interest will first be paid
            by the Master Servicer out of its Master Servicer Compensation on
            any Payment Date and any required Compensating Interest in excess of
            the Master Servicer Compensation will be paid by the Servicer out of
            its Servicing Fee. The Servicer will be reimbursed for all amounts
            paid by it in respect of Compensating Interest first, on the related
            Payment Date, from amounts that would otherwise be paid to the
            Residual Certificateholder and second, on subsequent Payment Dates,
            by the Master Servicer out of amounts otherwise payable in respect
            of the Master Servicer Compensation and amounts that would otherwise
            be payable to the Residual Certificateholder;
 
          o The Master Servicer will periodically review the servicing reports,
            loan level information and other relevant information as may be
            reasonably required by the Master Servicer to ascertain whether the
            Servicer is in compliance with the Servicing Agreement;
 
          o If the reports submitted by the Servicer are inaccurate or
            incomplete, then the Master Servicer will prepare and submit
            exception reports to the Indenture Trustee, the Securities Insurer
            and the Rating Agencies and notify the Indenture Trustee, the
            Securities Insurer and the Rating Agencies of any event of default
            with respect to the Servicer under the Servicing Agreement;
 
          o If the Servicer is terminated as Servicer under the Servicing
            Agreement, then the Master Servicer will accept appointment as, or
            cause another entity as directed by the Securities Insurer to act
            as, the successor servicer thereunder; and
 
          o The Master Servicer will either maintain computer systems and
            software compatible with the computer systems of the Servicer or
            will obtain computer systems allowing it to assume the servicing of
            the Loans, if necessary.
 
     Under the Servicing Agreement, the Servicer will facilitate the master
servicing functions of the Master Servicer as follows:
 
          o the Servicer will comply with the terms of the various agreements it
            is entering into in connection with the Loans, including but not
            limited to, the Transfer and Servicing Agreements;
 
          o the Servicer will provide to the Master Servicer certain information
            regarding the Loans and its servicing activities of such Loans;
 
          o the Servicer will permit the Master Servicer to inspect the
            Servicer's books and records; and
 
          o the Servicer will reimburse and indemnify the Master Servicer, the
            Issuer and the Indenture Trustee for certain losses, liabilities and
            expenses incurred by any of them.
 
     In certain limited circumstances and conditions, the Master Servicer may
resign or be removed by the Securities Insurer, in which event another
third-party master servicer will be sought to become the successor
 
                                      S-29
<PAGE>
master servicer. The Master Servicer has the right to resign under the Sale and
Master Servicing Agreement upon 60 days' notice any time on or after one year
from the Closing Date. No removal or resignation of the Master Servicer will
become effective until the Indenture Trustee, the Owner Trustee or a successor
master servicer, acceptable to the Securities Insurer, has assumed the Master
Servicer's responsibilities and obligations under the Sale and Master Servicing
Agreement.
 
     See "Description of the Transfer and Servicing Agreements" in this
prospectus supplement.
 
                                    SERVICER
 
GENERAL
 
     Fairbanks Capital Corp., a Utah corporation (the "Servicer"), will service
the Loans in accordance with the Servicing Agreement between the Master Servicer
and the Servicer (the "Servicing Agreement"). The Servicer was formed on
February 24, 1989. The Servicer is a FNMA approved seller/servicer and a FHLMC
approved servicer engaged in the servicing of first and junior lien mortgage
loans. The Servicer's corporate offices are located at 3815 South West Temple,
Salt Lake City, Utah 84165-0250. The Servicer commenced mortgage servicing
operations in 1989 for its own account and since 1994 has managed and serviced
third-party mortgage loan portfolios. Prior to 1998, the Servicer primarily
serviced portfolios of non-performing or delinquent residential mortgage loans.
 
     The Master Servicer will service the Loans for an interim period beginning
on the Closing Date and ending on or before May 1, 1999. During this time the
Master Servicer shall be entitled to all Servicing Compensation, and shall be
vested with all of the rights and obligations of the Servicer. The Master
Servicer will transfer the servicing of the Loans to the Servicer on or before
May 1, 1999 and thereafter the Servicer will perform the servicing functions
with respect to the Loans.
 
     The information contained herein with regard to the Servicer has been
provided to the Depositor, or compiled from information provided to the
Depositor, by the Servicer. None of the Depositor, the Indenture Trustee, the
Master Servicer, the Transferor, the Securities Insurer or any of their
respective affiliates has made any independent investigation of such information
or has made or will make any representation as to the accuracy or completeness
of such information.
 
SERVICING PROCEDURES
 
     The following is a general description of the Servicer's servicing policies
and procedures currently employed by the Servicer with respect to its
conventional loan portfolio. All references in this prospectus supplement to the
"Servicer" shall mean "Master Servicer" for purposes of the accompanying
prospectus. For a description of certain other servicing procedures applicable
to the Loans, see "Description of the Transfer and Servicing Agreements" in this
prospectus supplement. In response to changes and developments in the consumer
finance area (including economic, legal and technological developments), as well
as the refinement of the Servicer's servicing and collection procedures, the
Servicer's servicing policies and procedures for certain types of loans,
including the Loans, may change from time to time. The manner in which the
Servicer performs its servicing obligations will affect the amount and timing of
principal and interest payments on the Loans, which in turn will affect payments
to the holders of the Notes.
 
     The Servicer's loan servicing activities include responding to borrower
inquiries, processing and administering loan payments, reporting and remitting
principal and interest to trustees, investors and other interested parties,
collecting delinquent loan payments, evaluating and conducting loss mitigation
efforts, charging off uncollectible loans, and otherwise administering the
loans. The Servicer has developed loss mitigation methodologies for conventional
loans, which includes short sales with repayment plans, short pay-offs,
substitutions of collateral and modifications that use borrower-specific
repayment schedules. Servicing operations also include customer complaint
monitoring, maintenance of daily delinquency information, analysis and
monitoring of legal remedies (including collection litigation, and foreclosure
proceedings and dispositions), accounting for principal and interest, contacting
delinquent borrowers, handling borrower defaults, recording mortgages and
assignments, investor and securitization reporting, and management portfolio
reporting.
 
     The Servicer utilizes a computer-based loan servicing system. It provides
payment processing and cashier functions, automated payoff statements, on-line
collection, statement and notice mailing, along with a full range
 
                                      S-30
<PAGE>
of investor reporting information. The Servicer has installed a predictive
automated dialing system and computerized telephone loan inquiry system to
increase the productivity of its collections staff.
 
     Collection activity usually begins once a loan is 5 days delinquent
(without regard to any grace period). At this time, if payment has not been
received the "5-Day Notice" is sent. The focus of collection activity is
understanding the cause of, and finding a solution for, the delinquency.
Throughout the entire process there is a continual effort to contact the
borrower and make acceptable payment arrangements. Late notices are sent to
borrowers whose payment has not been received by the 11th day after the due
date. Borrowers whose loans are 16 days delinquent will receive written notice
that late fees have been imposed. If payment has not been received by the 21st
day, the "21-Day Late Notice" is sent. If the borrower cannot be contacted
within 15 days after the first attempted phone call, or at 20 days of
delinquency, a third party property inspection company may be engaged to visit
the borrower's home to complete an exterior inspection of the property securing
the loan, if applicable. The inspection provides specific details about the
property, including whether the property is vacant or occupied, and a notice is
left to call the Servicer's servicing department.
 
     If payment is not received by the 26th day of delinquency a notice advising
of the pending "Notice of Default" is sent via Western Union. The demand is sent
via either Western Union or certified mail, return receipt requested, and
regular first class mail. The demand requires the borrower to pay the full
amount due within 30 days to avoid further legal action. If the demand for
payment has expired with no plan for reinstatement, the loan will be submitted
to a default review committee. If the committee approves the foreclosure, the
loan is referred to the legal department to commence foreclosure proceedings in
accordance with applicable servicing agreement requirements. Between 15 and
30 days after the expiration of the demand, if the Servicer and the borrower
have not agreed on a plan to cure the default, the legal department will refer
the loan to local counsel for foreclosure. Again, continuous effort will be made
by telephone to remain in contact with the borrower while the loan is being
approved for foreclosure and even during the foreclosure process in an effort to
exhaust all avenues to cure the default.
 
     Under the Servicing Agreement, the Servicer may resign from its duties only
in accordance with the terms of the agreement. No removal or resignation will
become effective until the Master Servicer or a successor servicer has assumed
the Servicer's responsibilities and obligations under the Servicing Agreement.
 
     The Servicer may not assign its obligations under the Servicing Agreement.
Notwithstanding anything in the preceding sentence to the contrary, the Servicer
may delegate certain of its obligations to a sub-servicer pursuant to a
sub-servicing agreement. A sub-servicer must meet certain eligibility
requirements, as set forth in the Servicing Agreement, and each sub-servicing
agreement shall require that the Loans be serviced in a manner that is
consistent with the terms of the Servicing Agreement. The Servicer will not be
released of its servicing obligations and duties with respect to any subserviced
Loans. As of the Closing Date, the Servicer will not have subcontracted its
servicing obligations and duties to a sub-servicer with respect to the Loans.
 
     Delinquency and Loss Experience. The following tables set forth certain
information relating to:
 
          o the delinquency experience (including foreclosures in progress and
            bankruptcies) as of the end of indicated period, and
 
          o the loan loss experience for the indicated period
 
of those portfolios of one- to four- family residential mortgage loans that
consisted primarily of performing loans at the time the Servicer began servicing
such loans. The Servicer did not service any such portfolios prior to 1998. The
indicated periods of delinquency are based on the number of days past due on a
contractual basis.
 
DELINQUENCY AND LOSS EXPERIENCE MAY NOT BE APPLICABLE TO THE POOL
 
     It is unlikely that the delinquency experience of the Loans will correspond
to the delinquency experience of the Servicer's mortgage portfolios set forth in
the following tables. The statistics shown below represent the delinquency
experience of the Servicers' mortgage servicing portfolios only for the periods
presented, whereas the aggregate delinquency experience on the Loans will depend
on the results obtained over the life of the Loans. There can be no assurance
that the Loans will perform in a manner consistent with the delinquency or
foreclosure experience of the Servicer's mortgage servicing portfolios described
in this prospectus supplement. It should be noted that if the residential real
estate market should experience an overall decline in property values, the
actual rates of delinquencies and foreclosures could be higher than those
previously experienced by the Servicer. In
 
                                      S-31

addition, adverse economic conditions or other factors may affect the timely
payment by borrowers of scheduled payments of principal and interest on the
Loans and, accordingly, the actual rates of delinquencies and foreclosures with
respect to the Loans.

                             UNDERWRITING CRITERIA
 
GENERAL
 
     The Loans were underwritten or reunderwritten in accordance with Fremont's
underwriting standards (the "Fremont Guidelines"), which are designed to permit
mortgage lending to borrowers whose creditworthiness and repayment ability do
not satisfy the more stringent underwriting requirements used as standards for
FNMA and FHLMC. Fremont has established risk categories by which it aggregates
acceptable loans into groupings considered to have progressively greater risk
characteristics. A more detailed description of those risk categories applicable
to the Loans is set forth below.
 
     Fremont's underwriting of the Loans generally consisted of analyzing the
following as standards applicable to the Loans: the creditworthiness of a
borrower; the income sufficiency of a borrower's projected family income
relative to the mortgage payment and to other fixed obligations (including in
certain instances rental income from investment property); and the adequacy of
the mortgaged property (expressed in terms of Loan-to-Value Ratio) to serve as
the collateral for a mortgage loan.
 
     The Transferor has implemented a credit policy that provides a number of
guidelines to assist underwriters in the credit decision process. The
creditworthiness characteristics emphasized by the Transferor are the borrower's
Debt-to-Income Ratio, credit history and employment stability. The
"Debt-to-Income Ratio" for a borrower is calculated by dividing (x) the
borrower's total monthly payment obligations (including payments due under the
loan with the Transferor, but after any debt consolidation from the proceeds of
such loan), by (y) such borrower's monthly gross income.
 
     A credit bureau report that reflects the applicant's credit history is
obtained by the Transferor from an independent, nationally recognized
credit-reporting agency. The credit report typically contains information
reflecting delinquencies, repossessions, judgments, foreclosures, bankruptcies
and similar instances of adverse credit that can be discovered by a search of
public records. A loan applicant's credit report must be current (generally less
than 90 days old) at the time of application and is used to evaluate the
borrower's payment record and tendency to repay debts in a timely manner. A lack
of credit payment history will not necessarily preclude a loan if other
favorable borrower characteristics exist, including sufficient equity in the
property or an adequate Debt-to-Income Ratio.
 
     The calculation of the borrower's Debt-to-Income Ratio involves a careful
review of all debts listed on the credit report and the loan application, as
well as the verification of gross income. Other than with respect to "Stated
Income Applications" described below, a borrower's income is verified through
various means, including applicant interviews, written verifications with
employers, and the review of pay stubs, bank statements, tax returns, W-2's or
other acceptable forms of documentation. The Debt-to-Income Ratio is calculated
to determine if a borrower demonstrates sufficient income levels to cover or
satisfy all debt repayment requirements.
 
     Generally, each borrower would have been required to complete an
application designed to provide to the original lender pertinent credit
information concerning the borrower. As part of the description of the
borrower's financial condition, each borrower furnished information (which may
have been supplied solely in such application) with respect to its assets,
liabilities, income, credit history, employment history and personal
information, and furnished an authorization to apply for a credit report which
summarized the borrower's credit history with local merchants and lenders and
any record of past or present bankruptcy or foreclosure proceedings. The
borrower may have also been required to authorize verifications of deposits at
financial institutions where the borrower had demand or savings accounts. In the
case of investment properties, income derived from the mortgaged property may
have been considered for underwriting purposes. With respect to mortgaged
property consisting of vacation or second homes, generally no income derived
from the property was considered for underwriting purposes, but could be
considered as a compensating factor.
 
     Based on the data provided in the application, certain verifications (which
are not required with respect to "Stated Income Applications" or "Easy
Documentation" program as described below), and the appraisal or other valuation
of the mortgaged property, a determination was made by Fremont that the
borrower's monthly income would be sufficient to enable the borrower to meet its
monthly obligations on the mortgage loan and other expenses related to the
property (such as property taxes, utility costs, standard hazard insurance and
other,
 
                                      S-33
<PAGE>
fixed obligations other than housing expenses). In certain circumstances,
Fremont may also have considered the amount of liquid assets available to the
borrower after origination.
 
     Prospective borrowers may submit loan applications under one of three
programs, which differ from each other with respect to the requirements for the
verification of the income of the borrower and the source of funds required to
be deposited by the applicant in order to close the loan. Certain of the Loans
have been originated under "Easy Documentation" programs that require less
documentation and verification than do traditional "Full Documentation"
programs. Generally, under such a program, minimal investigation into a
borrower's income profile would have been undertaken by the originator and the
underwriting for such mortgage loans will place a greater emphasis on the value
of the mortgaged property and credit history. Under the "Easy Documentation"
program, applicants must have income evidenced by six months of personal bank
statements. Under the "Full Documentation" program, borrowers are generally
required to submit documentation verifying at least two years of income and
employment history. Under the "Stated Income Application" program, no
verification of the applicant's income is required; rather, the applicant may be
qualified based on monthly income as stated in the mortgage loan application, if
that income is supported by the general information included in the loan
application package.
 
     As used herein, "Loan-to-Value Ratio" shall generally mean that ratio,
expressed as a percentage of, (a) the principal amount of the Loan at
origination, over (b) the lesser of the sales price or the appraised value of
the related mortgaged property at origination, or in the case of a refinanced or
modified Loan, either the appraised valued determined at origination or, if
applicable, at the time of the refinancing or modification.
 
     The adequacy of a mortgaged property as security for repayment of the
related mortgage loan generally has been determined by an appraisal in
accordance with preestablished appraisal procedure Guidelines for appraisals
established by Fremont. Appraisers were typically licensed independent
appraisers selected in accordance with the Fremont Guidelines. The appraisal
procedure guidelines generally required the appraiser or an agent on its behalf
to inspect the property personally and to verify whether the property was in
good condition and that construction, if new, had been substantially completed.
The appraisal would have considered a market data analysis of recent sales of
comparable properties and, when deemed applicable, an analysis based on income
generated from the property or replacement cost analysis based on the current
cost of constructing or purchasing a similar property. The Loan-to-Value Ratio
has been supported by a review appraisal conducted by Fremont or an independent
review company.
 
     Pursuant to the Fremont Guidelines, each Loan was assigned a risk grade and
categorized in a "Loan Class," denominated by a letter. Fremont's risk
classification system is designed to assess the likelihood that each borrower
will satisfy the repayment obligations associated with the related mortgage loan
and to establish the maximum permissible Loan-to-Value Ratio for the mortgage
loan. Time frames referred to below (e.g., "within the last 12 months") are
measured from the time of underwriting of a borrower's credit.
 
     Loan Class A: For a Loan to have been assigned to a Loan Class A, the
prospective borrower must have overall "good" to "excellent" consumer credit. No
30-day, 60-day or 90-day late payments within the last 12 months are acceptable
on an existing mortgage loan, any existing mortgage loan must be current at the
time of the application and no notices of default within the last three years on
an existing mortgage loan are permitted. Minor derogatory items are allowed as
to non-mortgage credit (provided, open collections and charge-offs in excess of
$500 must be paid down to zero at closing unless they are three years old or
older and not reflected in the title report or are medical related). No Chapter
7 bankruptcies with respect to the borrower may have been discharged during the
previous three years, and no Chapter 13 bankruptcy filings may have been made by
the borrower during the previous three years. No foreclosures may have been
filed within the last three years with respect to borrower property or no
foreclosure sales with respect to borrower property may have been conducted
within the last three years. The mortgaged property must be in average to good
condition. A maximum Loan-to-Value Ratio of 90% is permitted for a mortgage loan
secured by a single family owner-occupied property (or 80% for a mortgage loan
originated under an "Easy Documentation" program and 80% for a mortgage loan
originated under a "Stated Income" application program). A maximum Loan-to-Value
Ratio of 80% (or 75% for mortgage loans originated under the "Easy
Documentation" program and 65% for mortgage loans originated under the "Stated
Income" application program) is permitted for a mortgage loan secured by a
non-owner occupied property. The maximum permissible Loan-to-Value Ratio is
lower for mortgage loans with initial principal amounts in excess of $300,000
secured by owner-occupied properties (or lower dollar amounts for
 
                                      S-34
<PAGE>
loans secured by non-owner-occupied properties), and for mortgage loans made in
connection with a borrower refinancing in which the borrower borrows more than
is needed to refinance his old mortgage loan. The borrower's debt
service-to-income ratio generally is 45% or less.
 
     Loan Class A-: For a Loan to have been assigned to Loan Class A-, the
prospective borrower is required to have overall "good" to "excellent" consumer
credit. A maximum of two 30-day late payments, and no 60-day or 90-day late
payments within the last 12 months is acceptable on an existing mortgage loan.
Any existing mortgage loan must be current at the time of the application and no
notices of default within the last three years on an existing mortgage loan are
permitted. As to non-mortgage credit, some prior defaults may have occurred
(provided, open collections and charge-offs in excess of $500 must be paid down
to zero at closing unless they are three years old or older and not reflected in
the title report or are medical related). No Chapter 7 bankruptcies with respect
to the borrower may have been discharged during the two years, and no
Chapter 13 bankruptcy filings may have been made by the borrower during the
previous two years. No foreclosures may have been filed within the last three
years with respect to borrower property or no foreclosure sales with respect to
the borrower property may have been conducted within the last two years. The
mortgaged property must be in average to good condition. A maximum Loan-to-Value
Ratio of 90% (or 80% for a loan originated under an "Easy Documentation" program
and 80% for a mortgage loan originated under a "Stated Income" application
program) is permitted for a mortgage loan secured by an owner-occupied property.
A maximum Loan-to-Value Ratio of 80% (or 75% for mortgage loans originated under
an "Easy Documentation" program and 65% for mortgage loans originated under a
Stated Income Application program) is permitted for a mortgage loan secured by
non-owner-occupied property. The maximum permissible Loan-to-Value Ratio is
lower for mortgage loans with initial principal amounts in excess of $300,000
secured by owner-occupied properties (or lower dollar amounts for loans secured
by non-owner-occupied properties), and for mortgage loans made in connection
with a borrower refinancing in which the borrower borrows more than is needed to
refinance his old mortgage loan. The debt service-to-income ratio generally is
50% or less.
 
     Loan Class B: For a Loan to have been assigned to Loan Class B, the
prospective borrower may not have paid all previous or existing installment or
revolving debt according to its terms and may have some charge-offs, and is
required to have overall "satisfactory" consumer credit. A maximum of four
30-day late payments, or two 30-day late payments and one 60-day late payment,
but no 90-day late payments, within the last 12 months is acceptable on an
existing mortgage loan and no notices of default within the last two years on an
existing mortgage loan are permitted. As to non-mortgage credit, some prior
defaults may have occurred (provided, open collections and chargeoffs must be
paid down to an amount not in excess of $500 at closing unless they are three
years old or older and not reflected in the title report or are medical
related). No Chapter 7 bankruptcies with respect to the borrower may have been
discharged during the previous two years, and no Chapter 13 bankruptcy filings
may have been made by the borrower during the previous two years. No
foreclosures may have been filed within the last two years with respect to
borrower property. A maximum Loan-to-Value Ratio of 85% (or 75% for a mortgage
loan originated under an "Easy Documentation" program and 75% for a mortgage
loan originated under a "Stated Income" application program) is permitted for a
mortgage loan secured by an owner-occupied property. A maximum Loan-to-Value
Ratio of 75% (or 70% for mortgage loans originated under an "Easy Documentation"
program and 65% for mortgage loans originated under a "Stated Income"
application program) is permitted for a mortgage loan secured by a
non-owner-occupied property. The maximum permissible Loan-to-Value Ratio is
lower for mortgage loans with initial principal amounts in excess of $300,000
secured by owner-occupied properties (or lower dollar amounts for loans secured
by non-owner-occupied properties), and for mortgage loans made in connection
with a borrower refinancing in which the borrower borrows more than is needed to
refinance his old mortgage loan. The debt service-to-income ratio generally is
50% or less.
 
     Loan Class C: For a Loan to have been assigned to Loan Class C, the
prospective borrower may have experienced significant credit problems in the
past, with overall "fair" consumer credit and a majority of credit not currently
delinquent. As to mortgage credit, the borrower may have had a history of being
generally 30 days delinquent, and a maximum of two 60-day late payments and one
90-day late payment within the last 12 months is acceptable on an existing
mortgage loan and no notices of default within the last twelve months (or
eighteen months if the Loan-to-Value Ratio is 75% or higher) or on an existing
mortgage loan are permitted. As to non-mortgage credit, significant prior
defaults may have occurred (provided, open collections and charge-offs must be
paid down to an amount not in excess of $1,500 at closing unless they are three
years old or older and not reflected in the title report or are medical
related). No bankruptcies may have been filed or discharged during the
 
                                      S-35
<PAGE>
12-month period prior to the date the mortgage loan was made. No foreclosures
may have been filed within the last year with respect to borrower property. The
mortgaged property must be in average to good condition. A maximum Loan-to-Value
Ratio of 80% (or 70% for a mortgage loan originated under an "Easy
Documentation" program and 70% for a mortgage loan originated under a "Stated
Income" application program) is permitted for a mortgage loan secured by an
owner-occupied property. A maximum Loan-to-Value Ratio of 70% (or 65% for
mortgage loans originated under an "Easy Documentation" program and 65% for
mortgage loans originated under a "Stated Income" application program) is
permitted for a mortgage loan secured by a non-owner-occupied property. The
maximum permissible Loan-to-Value Ratio is lower for mortgage loans with initial
principal amounts in excess of $300,000 secured by owner-occupied properties (or
lower dollar amounts for loans secured by non-owner occupied properties), and
for mortgage loans made in connection with a borrower refinancing in which the
borrower borrows more than is needed to refinance his old mortgage loan. The
debt service-to-income ratio generally is 55% or less.
 
     Loan Class C-: For a Loan to have been assigned to Loan Class C-, the
prospective borrower may have experienced significant credit problems in the
past, with overall "poor" consumer credit. As to mortgage credit, the borrower
may have had a history of being generally 30 days delinquent, is not more than
120-days delinquent on an existing mortgage loan and there may not be a current
notice of default outstanding on an existing mortgage loan. As to non-mortgage
credit, significant prior defaults may have occurred (provided, open collections
and charge-offs must be paid down to an amount not in excess of $1,500 at
closing unless they are three years old or older and not reflected in the title
report or are medical related). The mortgaged property must be in average to
good condition. A maximum Loan-to-Value Ratio of 70% (or 70% for a mortgage loan
originated under an "Easy Documentation" program and 65% for a mortgage loan
originated under a "Stated Income" application program) is permitted for a
mortgage loan secured by an owner-occupied property. A maximum Loan-to-Value
Ratio of 65% for all programs is permitted for a mortgage loan secured by a non-
owner-occupied property. The maximum permissible Loan-to-Value Ratio is lower
for mortgage loans with initial principal amounts in excess of $300,000 secured
by owner-occupied properties (or lower dollar amounts for loans secured by
non-owner occupied properties), and for mortgage loans made in connection with a
borrower refinancing in which the borrower borrows more than is needed to
refinance his old mortgage loan. The debt service-to-income ratio generally is
55% or less.
 
     Loan Class D: For a Loan to have been assigned to Loan Class D, the
prospective borrower will have experienced substantial credit problems in the
past, and generally will have overall poor credit. The prospective borrower's
credit history is poor and a notice of default on an existing mortgage loan may
have been filed against the borrower. As to non-mortgage credit, significant
prior defaults may have occurred (provided, open collections and charge-offs
must be paid down to an amount not in excess of $2,500 at closing unless they
are three years old or older and not reflected in the title report or are
medical related). A bankruptcy filing by the borrower is permitted if it is
discharged at closing. Also, on a case-by-case basis, Fremont may make a loan on
a mortgage that takes a borrower out of foreclosure. Fremont will make a
mortgage loan to a borrower to take him out of bankruptcy or foreclosure only if
it improves the borrower's financial situation. The mortgaged property must be
in average to good condition. A maximum Loan-to-Value Ratio of 65% is permitted
for mortgage loans originated under a full documentation program, "Easy
Documentation" program or "Stated Income" application program. A maximum
Loan-to-Value Ratio of 60% for mortgage loans originated under a full
documentation program, "Easy Documentation" program or "Stated Income"
application program is permitted for a mortgage loan secured by a
non-owner-occupied property. The maximum permissible Loan-to-Value Ratio is
lower for mortgage loans with initial principal amounts in excess of $300,000
secured by owner-occupied properties (or lower dollar amounts for loans secured
by non-owner-occupied properties), and for mortgage loans made in connection
with a borrower refinancing in which the borrower borrows more than is needed to
refinance his old mortgage loan. The debt service-to-income ratio generally is
65% or less.
 
     As described above, the indicated underwriting standards applicable to the
Loans include the foregoing categories and characteristics as guidelines only.
On a case-by-case basis, Fremont may have determined in the course of its
underwriting process that a prospective borrower warrants a Loan-to-Value Ratio
upgrade based on compensating factors. For example, a borrower may be able to
get a loan in a particular Loan Class with a Loan-to-Value Ratio 5% higher than
the ratio that would otherwise be permitted for such Loan Class if certain
compensating factors exist.
 
                                      S-36
<PAGE>
     Based on the indicated underwriting standards applicable for mortgage loans
with risk features originated thereunder, and in particular Loans in Loan
Classes C- and D as described herein, such Loans are likely to experience
greater rates of delinquency, foreclosure and loss, and may experience
substantially greater rates of delinquency, foreclosure and loss, than mortgage
loans underwritten under more stringent underwriting standards.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
GENERAL
 
     The yield on the Notes will be sensitive to fluctuations in the level of
One-Month LIBOR and the Net Funds Cap. In addition, because the rate and timing
of principal payments on the Notes depends primarily on the rate and timing of
principal payments (i.e., the prepayment experience) of the Loans and the
availability and amount of Excess Spread, the final payment of principal on the
Notes could occur significantly earlier than the Maturity Date. If significant
principal payments are made on the Notes, the holders of the Notes may not be
able to reinvest such payments in a comparable alternative investment having a
comparable yield. No prediction can be made as to the rate of prepayments on the
Loans in either stable or changing interest rate environments. Any reinvestment
risk resulting from the rate of prepayments on the Loans will be borne entirely
by the holders of such Notes.
 
     The rate of principal payments on the Notes, the aggregate amount of each
interest payment on the Notes and the yield to maturity on the Notes will be
directly related to and affected by: (i) the prepayment experience of the Loans;
(ii) the application of Excess Spread to reduce the Note Principal Balance of
the Notes to the extent described in this prospectus supplement under
"Description of Credit Enhancement--Overcollateralization," and (iii) under
certain circumstances, the rates of delinquencies, defaults or losses
experienced on the Loans. The prepayment experience of the Loans will be
affected by: (1) the scheduled amortization of the Loans; and (2) any
unscheduled principal prepayments or reductions of the Loans, which may include
(a) borrower prepayments and refinancings, (b) liquidations, write-offs and
certain modifications of the Loans due to defaults, casualties, condemnations or
other dispositions, and (c) repurchases of defective and defaulted Loans
pursuant to the Transfer and Servicing Agreements. Certain modifications of
defaulted Loans by the Servicer may have the effect of delaying or decreasing
principal reductions that would have otherwise occurred on such defaulted Loans.
On or after any Payment Date on which the Pool Principal Balance declines to 10%
or less of the Cut-Off Date Pool Principal Balance, the Majority Residual
Interest Certificateholders may purchase all of the Loans from the Issuer at a
price equal to or greater than the Termination Price, thereby resulting in a
redemption of the Notes. Furthermore, to the extent that the Majority Residual
Interest Certificateholders fail to exercise such optional redemption rights,
the Securities Insurer and the Servicer may be entitled to exercise a similar
right to effect an optional redemption of the Notes if the Pool Principal
Balance declines to 5% or less of the Cut-Off Date Pool Principal Balance. See
"Description of the Notes--Optional Redemption" in this prospectus supplement.
 
     The "weighted average life" of a Note refers to the average amount of time
that will elapse from the Closing Date to the date each dollar in respect of
principal of such Note is repaid. The weighted average life of a Note will be
influenced by, among other factors, the following: (1) the prepayment experience
of the Loans; (2) the rate at which Excess Spread is paid to holders of such
Notes; (3) the extent to which any reduction of the Overcollateralization Amount
is paid to the holders of the Residual Interest Certificates; and (4) under
certain circumstances, the rates of delinquencies, defaults or losses
experienced on the Loans. If substantial principal prepayments on the Loans are
received from unscheduled prepayments, liquidations or repurchases, then the
payments to the holders of the Notes resulting from such prepayments may
significantly shorten the actual average lives of such Notes. If the Loans
experience delinquencies and certain defaults in the payment of principal, then
the holders of the Notes may similarly experience a delay in the receipt of
principal payments attributable to such delinquencies and defaults which in
certain instances may result in longer actual average lives of such Notes than
would otherwise be the case. However, to the extent that the Principal Balances
of Liquidated Home Loans are included in the principal payments on the Notes
then the holders of such Notes will experience an acceleration in the receipt of
principal payments which in certain instances may result in shorter actual
average lives of such Notes than would otherwise be the case. See "Risk
Factors--Adequacy of Credit Enhancement" in this prospectus supplement.
 
     The prepayment experience of the Loans will be influenced by a variety of
general economic and social factors, as well as other factors and
characteristics that relate specifically to each Loan. Factors that relate
specifically to the Loans and that may affect the prepayment rate of the Loans
include the following: (1) the
 
                                      S-37
<PAGE>
outstanding principal balances of the Loans; (2) the interest rates on the
Loans; (3) changes in the value of the related Mortgaged Properties and the
related Loan-to-Value Ratios; (4) changes in the creditworthiness of the
borrowers; (5) changes in the availability of comparable financing to the
borrowers on either more or less favorable terms; and (6) changes in the
borrowers' housing needs or employment status. Additional factors that relate to
the Loans on a specific basis include the seasoning of the Loans, the existence
and enforceability of "due-on-sale" clauses, and the existence and
enforceability of prepayment penalties. For example, certain of the Loans
contain due-on-sale provisions and the Servicer intends to enforce such
provisions, unless (i) the Servicer, in a manner consistent with the accepted
servicing procedures, permits the purchaser of the related Mortgaged Property to
assume the Loan, or (ii) such enforcement is not permitted by applicable law.
See "Certain Legal Aspects of Residential Loans--Enforceability of Certain
Provisions" in the accompanying prospectus. In certain cases, if the borrower is
selling its Mortgaged Property, the Servicer, in a manner consistent with the
accepted servicing procedures, may permit a substitution of collateral, short
sales, short pay-offs or other modifications. See "Description of the Transfer
and Servicing Agreements--Realization Upon Defaulted Loans" in this prospectus
supplement. Certain of the Loans contain prepayment penalties, which generally
obligate the related borrower to pay penalties in connection with a prepayment
of the borrower's Loan. The Servicer will enforce prepayment penalties unless
doing so would be unlawful or the Master Servicer consents to waiver. The Master
Servicer has no obligation to enforce prepayment penalties and will exercise its
rights to enforce them to the extent it deems appropriate. In addition, the
prepayment penalties are typically suspended during the 60-day period that
coincides with the initial adjustment date for a Loan, where applicable. The
Master Servicer is entitled to retain all prepayment penalties to the extent the
Servicer collects such from borrowers. The existence of prepayment penalties and
any enforcement by the Master Servicer of the prepayment penalties contained in
the Loans may have an effect on the decisions of borrowers to prepay their Loans
and thus may affect the weighted average lives of the Notes.
 
     Other general economic and social factors that may affect the prepayment
rate of the Loans, include, among other matters, the rate of inflation,
unemployment levels, personal bankruptcy levels, prevailing interest rates,
consumer spending and saving habits, competition within the mortgage and
consumer finance industries, and consumer, bankruptcy and tax law developments.
For example, any further limitations on the rights of borrowers to deduct
interest payments on mortgage loans for federal income tax purposes may result
in a higher rate of prepayments on the Loans. In addition, the rate of
prepayment on a pool of mortgage loans is generally affected by prevailing
market interest rates for similar types of loans of a comparable term and risk
level. If prevailing interest rates were to fall significantly below the
respective Loan Rates on the Loans, the rate of prepayment (and refinancing)
would be expected to increase. Conversely, if prevailing interest rates were to
rise significantly above the respective Loan Rates on the Loans, the rate of
prepayment on the Loans would be expected to decrease. Depending on prevailing
market interest rates, the outlook for market interest rates, and economic
conditions generally, some borrowers may sell or refinance their mortgaged
properties to realize their equity in order to meet cash flow needs or to make
other investments.
 
     As a result of the foregoing general economic and social factors, as well
as the loan specific factors and characteristics, the prepayment experience of
the Loans (1) cannot be predicted with certainty, (2) will be likely to
fluctuate over the life of the Loans and (3) may differ significantly from the
prepayment rates of other similar loans. None of the Transferor, the Servicer,
the Master Servicer, the Securities Insurer, the Depositor, nor the Underwriters
makes any representation as to the particular factors that will affect the
prepayment of the Loans, as to the relative importance of such factors, or as to
the percentage of the principal balances of the Loans that will be paid as of
any date.
 
     Payments of principal to holders of the Notes at a faster rate than
anticipated will increase the yields on such Notes purchased at discounts but
will decrease the yields on such Notes purchased at premiums, which payments of
principal may be attributable to scheduled payments and prepayments of principal
on the Loans and to the application of Excess Spread. The effect on an
investor's yield due to payments of principal to the holders of such Notes
(including, without limitation, prepayments on the Loans) occurring at a rate
that is faster (or slower) than the rate anticipated by the investor during any
period following the issuance of such Notes will not be entirely offset by a
subsequent like reduction (or increase) in the rate of such payments of
principal during any subsequent period.
 
     The rate of delinquencies and defaults on the Loans, and the recoveries, if
any, on defaulted Loans and foreclosed properties, will also affect the
prepayment experience of the Loans and, accordingly, the weighted average lives
of the Notes. To the extent that such delinquencies, defaults and losses cause a
reduction in the
 
                                      S-38
<PAGE>
amount of Excess Spread, then payments of principal to the holders of the Notes
could be delayed and result in a slower rate of principal amortization of the
Notes. See "Description of Credit Enhancement--Overcollateralization" in this
prospectus supplement. However, to the extent that such delinquencies, defaults
and losses cause an increase in the Overcollateralization Deficiency Amount,
then an increasing amount of Excess Spread may be applied to the payment of
principal to the holders of the Notes and result in a faster rate of principal
amortization of the Notes. If the Overcollateralization Amount is reduced to
zero, then such defaults and losses would cause an increase in the payment of
principal to the holders of the Notes to the extent that such defaults or losses
are covered by the credit enhancement available for the Notes, including the
Guaranty Policy. Several factors may influence such delinquencies, defaults and
losses: the outstanding Loan principal balances; the related Loan-to-Value
Ratios; and other underwriting standards for such Loans. In general, defaults on
mortgage loans are expected to occur with greater frequency in their early
years, although few data are available with respect to the rate of default on
home loans similar to the Loans. See "Risk Factors--Realization Upon Defaulted
Loans" and "Underwriting Criteria" in this prospectus supplement. Furthermore,
the rate and timing of prepayments, delinquencies, defaults, liquidations and
losses on the Loans will be affected by the general economic condition of the
region of the country in which the related Mortgaged Properties are located or
the related borrowers are residing. See "Risk Factors--Geographic Concentration"
and "The Pool" in this prospectus supplement. The risk of delinquencies,
defaults and losses is greater and voluntary principal prepayments are less
likely in regions where a weak or deteriorating economy exists, as may be
evidenced by, among other factors, increasing unemployment or falling property
values.
 
EXCESS SPREAD AND REDUCTION OF OVERCOLLATERALIZATION AMOUNT
 
     The overcollateralization feature has been designed to accelerate the
principal amortization of the Notes relative to the principal amortization of
the Loans. If on any Payment Date, the Overcollateralization Target Amount
exceeds the Overcollateralization Amount, Excess Spread, if any, will be paid as
principal to the holders of the Notes in the amounts described under
"Description of the Notes--Priority of Payments" in this prospectus supplement.
If the Overcollateralization Amount equals or exceeds the Overcollateralization
Target Amount for such Payment Date, Excess Spread otherwise payable to the
holders of the Notes will instead be paid to the holders of the Residual
Interest Certificates. On any Payment Date after the Stepdown Date as to which
the Overcollateralization Amount is, or after taking into account all other
payments to be made on such Payment Date, would be at least equal to the
Overcollateralization Target Amount, principal collections on the Loans
otherwise payable as principal to the holders of the Notes on such Payment Date
in reduction of their Note Principal Balance may instead be paid to the holders
of the Residual Interest Certificates, thereby reducing the rate of, and under
certain circumstances delaying, the principal amortization of such Notes, until
the Overcollateralization Amount is reduced to the Overcollateralization Target
Amount.
 
     The yield to maturity on Notes purchased at a premium or discount will be
affected by the extent to which any Excess Spread is paid to holders of the
Notes or is paid to the holders of the Residual Interest Certificates, in lieu
of payment to such holders of the Notes. If such Excess Spread payments to the
holders of the Residual Interest Certificates occur sooner than anticipated by
an investor who purchases Notes at a discount, the actual yield to such investor
may be lower than anticipated. If such Excess Spread payments to the holders of
the Residual Interest Certificates occur later than anticipated by an investor
who purchases Notes at a premium, the actual yield to such investor may be lower
than anticipated. In particular, high rates of delinquencies on the Loans during
any Due Period will cause the Excess Spread available on the related Payment
Date to be reduced. Such an occurrence may cause the Note Principal Balance of
the Notes to amortize at a slower rate relative to the Pool Principal Balance,
resulting in a possible reduction of the Overcollateralization Amount.
 
     If the Securities Insurer changes the Overcollateralization Target Amount
or the delinquency or loss levels or excess spread requirements that determine
whether the Overcollateralization Target Amount will increase or decrease, your
principal on the Notes may be paid more slowly or quickly than otherwise would
be the case. This could adversely affect the yield to maturity of your Notes.
See "--Reinvestment Risk" and "Description of Credit
Enhancement--Overcollateralization" in this prospectus supplement.
 
REINVESTMENT RISK
 
     The reinvestment risk with respect to an investment in the Notes will be
affected by the rate and timing of principal payments (including prepayments) in
relation to the prevailing interest rates at the time of receipt of such
principal payments. For example, during periods of falling interest rates,
holders of the Notes may receive
 
                                      S-39
<PAGE>
an increased amount of principal payments from the Loans at a time when such
holders may be unable to reinvest such payments in investments having a yield
and rating comparable to their respective Notes. Conversely, during periods of
rising interest rates, holders of the Notes may receive a decreased amount of
principal prepayments from the Loans at a time when such holders may have an
opportunity to reinvest such payments in investments having a higher yield than,
and a comparable rating to, their respective Notes. If the Securities Insurer
changes the Overcollateralization Target Amount or the delinquency or loss
levels or excess spread requirements that determine whether the
Overcollateralization Target Amount will increase or decrease, your principal on
the Notes may be paid more slowly or quickly than may otherwise be the case.
This could adversely affect your reinvestment risk.
 
MATURITY DATE
 
     The Maturity Date of the Notes was determined by adding one year to the
Payment Date which occurs in the month following the maturity date of the latest
maturing Loan. The actual maturity of the Notes may be significantly earlier
than the Maturity Date.
 
YIELD CONSIDERATIONS RELATING TO ADJUSTABLE-RATE LOANS
 
     During the initial period following origination, substantially all of the
Adjustable-Rate Loans bore interest at Loan Rates which were set independently
of the Six-Month LIBOR applicable at the time of origination. See "The
Pool--Payments on the Loans" in this prospectus supplement.
 
     At the initial Change Date for each Adjustable-Rate Loan, the Loan Rate was
or will be adjusted to a rate based on the applicable Six-Month LIBOR plus the
related Gross Margin, subject to the applicable Periodic Rate Cap and applicable
Lifetime Cap and Lifetime Floor. On a Change Date, increases in Six-Month LIBOR
will increase the Loan Rates of the Adjustable-Rate Loans, subject to the
applicable Periodic Rate Cap and the applicable Lifetime Cap. Resulting
increases in the amount of the required monthly payments on the Adjustable-Rate
Loans in excess of those assumed in underwriting such Adjustable-Rate Loans may
result in a default rate higher than that on mortgage loans with fixed mortgage
rates.
 
     Notwithstanding prevailing market interest rates, in the event the Loan
Rate on any Adjustable-Rate Loan cannot increase above a certain level due to
the applicable Periodic Rate Cap or the applicable Lifetime Cap, the yield on
the Notes could be adversely affected. In addition, should the Loan Rate on any
Adjustable-Rate Loan not be able to decrease below a certain level due to the
applicable Lifetime Floor or Periodic Rate Cap, the related borrower may be more
likely to prepay such Adjustable-Rate Loan in full in order to refinance at a
lower rate.
 
     The Loan Rates on the Adjustable-Rate Loans adjust periodically based upon
Six-Month LIBOR, whereas the Note Interest Rate adjusts monthly based upon
One-Month LIBOR as described under "Description of the Notes" herein, subject to
a Net Funds Cap. The interest due on the Adjustable-Rate Loans during any Due
Period may not equal the amount of interest that would accrue on the Notes
during the related Accrual Period, and, to the extent any shortfall is created
as a result, any such shortfall will only be paid to Noteholders to the extent
and in the priority described under "Description of the Notes--Payments on the
Notes" herein. In addition, Six-Month LIBOR and One-Month LIBOR may respond to
different economic and market factors, and there is not necessarily a
correlation between them. Thus, it is possible, for example, that One-Month
LIBOR may rise during periods in which Six-Month LIBOR is stable or is falling
or that, even if both One-Month LIBOR and Six-Month LIBOR rise during the same
period, One-Month LIBOR may rise more rapidly than Six-Month LIBOR.
 
     The Transferor is not aware of any publicly available statistics that set
forth principal prepayment experience or prepayment forecasts of adjustable-rate
mortgage loans over an extended period of time, and its experience with respect
to such loans is insufficient to draw any conclusions with respect to the
expected prepayment rates on the Adjustable-Rate Loans. The rate of principal
prepayments with respect to adjustable-rate mortgage loans has fluctuated in
recent years. In addition, the features of adjustable-rate mortgage loan
programs in the past have varied significantly in response to market conditions
such as interest rates, consumer demand, regulatory restrictions and other
factors. The lack of uniformity of the terms and provisions of such adjustable-
rate mortgage loan programs has made it impracticable to compile meaningful
comparative data on prepayment rates and, accordingly, there can be no certainty
as to the rate of prepayments on the Adjustable-Rate Loans in stable or changing
interest rate environments. As is the case with conventional fixed-rate mortgage
loans, adjustable-rate mortgage loans may be subject to a greater rate of
principal prepayment in a declining interest rate environment. For example, if

subject to higher prepayment rates than if prevailing interest rates remain
constant because the availability of fixed-rate mortgage loans at competitive
interest rates may cause borrowers to refinance their adjustable-rate mortgage
loans in order to obtain lower fixed interest rates.
 
WEIGHTED AVERAGE LIVES OF THE NOTES
 
     The following information is given solely to illustrate the effect of
prepayments of the Loans on the weighted average lives of the Notes under
certain stated assumptions and is not a prediction of the prepayment rate that
may actually be experienced by the Loans. Weighted average lives of the Notes,
refers to the average amount of time that will elapse from the date of delivery
of the Notes until each dollar of principal of the Notes will be repaid to the
investor on the Notes. The weighted average lives of the Notes will be
influenced by the rate at which principal of the Loans is paid, which may be in
the form of scheduled amortization or prepayments (for this purpose, the term
"prepayment" includes reductions of principal, including, without limitation,
those resulting from unscheduled full or partial prepayments, refinancings,
liquidations and write-offs due to defaults, casualties or other dispositions
and substitutions and repurchases by or on behalf of the Transferor), the rate
at which Excess Spread is paid to holders of the Notes, the extent to which any
reduction in Overcollateralization Amount is paid to the Residual Interest
Certificates and the rate of delinquencies and losses on the Loans from time to
time. See "Description of Credit Enhancement--Overcollateralization" in this
prospectus supplement.
 
     The model used in this prospectus supplement is the constant prepayment
rate ("CPR") which represents an assumed rate of prepayment each month to the
then outstanding principal balance of a pool of loans for the life of such
loans. CPR does not purport to be a historical description of prepayment
experience or a prediction of the anticipated rate of prepayment of any pool of
loans, including the Loans. The Transferor believes that no existing statistics
of which it is aware provide a reliable basis for the holders of the Notes to
predict the amount or the timing of receipt of prepayments on the Loans.
 
     Modeling assumptions. For purposes of preparing the tables below, the
following assumptions (the "Modeling Assumptions") have been made:
 
          (1) all scheduled principal payments on the Loans are timely received
     on the first day of each Due Period, with the first Due Period for the
     Loans commencing on March 2, 1999, and no delinquencies or losses occur on
     the Loans;
 
          (2) the scheduled payments on the Loans have been calculated on the
     outstanding Principal Balance (before giving effect to prepayments), the
     Loan Rate and the remaining term to stated maturity such that the Loans
     will fully amortize by their remaining term to stated maturity;
 
          (3) all scheduled payments of interest and principal in respect of the
     Loans have been made through the Cut-Off Date;
 
          (4) the Loan Rate on each Adjustable-Rate Loan is adjusted on its next
     Change Date (and subsequent Change Dates, if necessary) to equal the sum of
     (a) an assumed level of Six-Month LIBOR (equal to 5.06%) and (b) the Gross
     Margin (subject to the Periodic Rate Caps, the Lifetime Cap and the
     Lifetime Floor);
 
          (5) LIBOR remains constant at 4.9375% per annum;
 
          (6) all Loans prepay monthly at the specified percentage of CPR, no
     optional or other early termination of the Notes occurs (except with
     respect to the calculation of the "Weighted Average Life-to-Call (Years)"
     figures in the following tables) and no substitutions or repurchases of the
     Loans occur;
 
          (7) all prepayments in respect of the Loans include 30 days' accrued
     interest;
 
          (8) the Closing Date for the Notes is March 23, 1999;
 
          (9) each year will consist of twelve 30-day months;
 
          (10) cash payments in full are received by the holders of the Notes on
     the 25th day of each month, commencing in April 1999;
 
          (11) the Overcollateralization Target Amount will be 4.00% of the
     Cut-Off Date Pool Principal Balance with respect to any Payment Date prior
     to the Stepdown Date and the greater of (a) 8.00% of the Pool Principal
     Balance and (b) 0.50% of the Cut-Off Date Pool Principal Balance
     thereafter;
 
                                      S-41
<PAGE>
          (12) the Note Interest Rate for the Notes is a per annum rate equal to
     One-Month LIBOR plus 0.30%; provided, however, that the Note Interest Rate
     on the Notes will be increased commencing on the Call Option Date, as
     described herein;
 
          (13) all Servicing Fees and Master Servicer Fees assumed to be
     deducted from the interest collections in respect of the Loans equal 0.50%
     of the Pool Principal Balance;
 
          (14) other fees and expenses assumed to be deducted from the interest
     collections in respect of the Loans equal 0.22% of the principal balance of
     the Notes;
 
          (15) no reinvestment income from any Account is earned and available
     for payment; and
 
          (16) the Pool consists of Loans having the following characteristics:

     The pay-down scenarios for the Notes set forth in the foregoing table is
subject to significant uncertainties and contingencies (including those
discussed above under this caption "Prepayment and Yield Considerations"). As a
result, neither the foregoing pay-down scenarios nor the Modeling Assumptions on
which they were made will likely prove to be accurate. Indeed, the actual
weighted average lives of the Notes will likely vary from those set forth in the
foregoing table, which variations may be shorter or longer, and which variations
may be greater with respect to later years. Furthermore, the Loans in all
likelihood will not prepay at a constant rate or at the same rate. Moreover, the
payment experience of the Loans and certain other factors affecting the payments
on the Notes will not conform to the Modeling Assumptions. In fact, the
characteristics and payment experience of the Loans will differ in many respects
from the Modeling Assumptions. See "The Pool" in this prospectus supplement. To
the extent that the Loans actually included in the Pool have characteristics and
a payment experience that differ from those assumed in preparing the foregoing
tables, the Notes are likely to have weighted average lives that are shorter or
longer than those set forth in the foregoing tables. See "Risk Factors--Yield,
Prepayment and Maturity Considerations" in this prospectus supplement.
 
     In light of the uncertainties inherent in the foregoing pay-down scenarios,
the inclusion of the weighted average lives of the Notes in the foregoing table
should not be regarded as a representation by the Transferor, the Depositor, the
Underwriters or any other person that any of the above pay-down scenarios will
be experienced.
 
                         THE OWNER TRUST AND INDENTURE
 
GENERAL
 
     Fremont Home Loan Owner Trust 1999-1 (the "Owner Trust" or the "Issuer") is
a business trust to be formed under the laws of the State of Delaware pursuant
to the Owner Trust Agreement (the "Owner Trust Agreement") among the Depositor,
the Paying Agent, the Owner Trustee and Fremont. On the Closing Date, the
Depositor will sell the Loans to the Issuer pursuant to a Sale and Master
Servicing Agreement. After its formation, the Issuer, as an Owner Trust, will
not engage in any activity other than the activities related to the Notes, which
will include:
 
o acquiring and holding the Loans and the other assets of the Issuer and
  proceeds therefrom,
 
o issuing the Notes and the Residual Interest Certificates,
 
o making payments on the Notes and distributions on the Residual Interest
  Certificates, and
 
o engaging in other activities that are necessary, suitable or convenient to
  accomplish the foregoing or are incidental thereto or in connection therewith.
 
     The Residual Interest Certificates represent the residual interest in the
assets of the Issuer. The Issuer will initially be capitalized with equity equal
to the value of the Residual Interest Certificates. The Residual Interest
Certificates, together with the Notes, will be transferred by the Issuer to the
Depositor as consideration for the Loans pursuant to the Sale and Master
Servicing Agreement. The Residual Interest Certificates will thereupon be
transferred by the Depositor to the Transferor as partial consideration for the
Loans.
 
     The assets of the Issuer will consist primarily of the Loans and all
amounts distributable thereon. The assets of the Issuer also will include
 
          (1) amounts on deposit in the Collection Account, Note Payment Account
     and the Certificate Distribution Account;
 
          (2) payments of principal and interest in respect of the Loans
     received after the Cut-Off Date;
 
          (3) an assignment of the Depositor's rights under the Home Loan
     Purchase Agreement;
 
          (4) an assignment of the Transferor's rights under the Servicing
     Agreement; and
 
          (5) certain other ancillary or incidental funds, rights and properties
     related to the foregoing. The Issuer's principal offices will be located in
     Wilmington, Delaware, in care of Wilmington Trust Company, (the "Owner
     Trustee"), at the address set forth below under "--The Owner Trustee."
 
                                      S-44
<PAGE>
THE OWNER TRUSTEE
 
     Wilmington Trust Company, a Delaware banking corporation, will act as the
Owner Trustee under the Owner Trust Agreement. Wilmington Trust Company is a
Delaware banking corporation and its principal offices are located at Rodney
Square North, 1100 North Market Street, Wilmington, Delaware 19890-0001.
 
     Certain functions of the Owner Trustee under the Owner Trust Agreement and
the Sale and Master Servicing Agreement will be performed by the Indenture
Trustee, including maintaining the Certificate Distribution Account and making
distributions to the Residual Interest Certificates.
 
THE INDENTURE TRUSTEE
 
     On the Closing Date, the Issuer will pledge the Loans and its other assets
under an Indenture (the "Indenture") between the Issuer and First Union National
Bank, a national banking association ("First Union"), as the indenture trustee
(in such capacity, the "Indenture Trustee"). First Union also will act:
 
o as the paying agent under the Owner Trust Agreement (in such capacity, the
  "Paying Agent"),
 
o as the custodian (in such capacity, the "Custodian") under the Custodial
  Agreement (the "Custodial Agreement") between the Custodian, the Issuer and
  the Indenture Trustee, and
 
o as the administrator (in such capacity, the "Administrator") under the
  Administration Agreement (the "Administration Agreement") among the Issuer,
  the Administrator and the Master Servicer.
 
                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Issuer will issue one class of notes (the "Notes") pursuant to the
Indenture. The assets of the Issuer will secure the Notes under the Indenture.
The Notes will have an approximate aggregate original principal balance (the
"Original Note Principal Balance") of $418,342,161 and will bear interest at a
per annum rate (the "Note Interest Rate") equal to the lesser of (i) One-Month
LIBOR plus 0.30%, provided that on any Payment Date on or after the Call Option
Date, this rate shall be One-Month LIBOR plus 0.60%; and (ii) the Net Interest
Rate.
 
     The "Net Interest Rate" for any Payment Date will be equal to the
annualized percentage derived from the fraction (which shall not be greater than
1), the numerator of which is the positive difference, if any, between the
amount of all interest due on the Loans during the related Due Period and the
Interest Reduction Amount and the denominator of which is the aggregate
principal amount of the Notes immediately prior to such Payment Date. The
"Interest Reduction Amount" for any Payment Date will be equal to the sum of the
Servicing Fee, the Master Servicer Fee, the Indenture Trustee Fee and the
Guaranty Insurance Premium; provided that on any Payment Date on or after the
Payment Date occurring in April 2000, the Interest Reduction Amount will be
increased by an amount equal to one-twelfth of the product of 0.50% and the
aggregate Principal Balance of the Loans as of the first day of the related Due
Period.
 
     The Issuer will also issue certificates (the "Residual Interest
Certificates") evidencing the ownership interest in the Issuer pursuant to the
Owner Trust Agreement. The Residual Interest Certificates are not being offered
through this prospectus supplement or the accompanying prospectus.
 
     On each Payment Date the Indenture Trustee or its designee will be required
to pay to the persons in whose names the Notes are registered on the last
Business Day of the month immediately preceding the month of the related Payment
Date (each such date, a "Record Date"), the portion of the aggregate payment to
be made to each holder of a Note as described below. Before any termination of
the book-entry provisions, payments on the Notes will be made to persons with
beneficial ownership interests in the Notes (the "Security Owners") only through
The Depository Trust Company ("DTC") and Participants in the United States, or
Cedelbank, societe anonyme or the Euroclear System, or indirectly through
Participants in such systems in Europe. See "Description of the
Securities--Book-Entry Registration of Securities" in the accompanying
prospectus.

     Beneficial ownership interests in the Notes may only be held in minimum
denominations of $25,000 and integral multiples of $1,000 in excess thereof;
provided, however, that one Note may be issued in such denomination as may be
necessary to represent the remainder of the aggregate amount of Notes.
 
     "One-Month LIBOR" shall mean the London interbank offered rate for
one-month United States dollar deposits. One-Month LIBOR for each Accrual Period
shall be determined on the second business day preceding the first day of any
such Accrual Period (each, a "LIBOR Determination Date"), on the basis of the
offered rates of the Reference Banks for one-month United States dollar
deposits, as such rates appear on the Telerate Screen Page 3750, as of 11:00
a.m. (London time) on such LIBOR Determination Date. As used in this paragraph,
"business day" means a day on which banks are open for dealing in foreign
currency and exchange in London and New York City; and "Reference Banks" means
leading banks selected by the Indenture Trustee and engaged in transactions in
Eurodollar deposits in the international Eurocurrency market (i) with an
established place of business in London, (ii) whose quotations appear on the
Telerate Screen Page 3750 on the LIBOR Determination Date in question, (iii)
which have been designated as such by the Indenture Trustee and (iv) which are
not controlling, controlled by or under common control with the Issuer, the
Depositor or the Transferor.
 
     On each LIBOR Determination Date, One-Month LIBOR will be established by
the Indenture Trustee as follows:
 
          (a) If on such LIBOR Determination Date two or more Reference Banks
     provide such offered quotations, One-Month LIBOR shall be the arithmetic
     mean (rounded upwards if necessary to the nearest whole multiple of
     0.0625%) of such offered quotations.
 
          (b) If on such LIBOR Determination Date fewer than two Reference Banks
     provide such offered quotations, One-Month LIBOR shall be the greater of
     (x) One-Month LIBOR as determined on the previous LIBOR Determination Date
     and (y) the Reserve Interest Rate. The "Reserve Interest Rate" shall be the
     rate per annum that the Indenture Trustee determines to be either (i) the
     arithmetic mean (rounded upwards if necessary to the nearest whole multiple
     of 0.0625%) of the one-month U.S. dollar lending rates which New York City
     banks selected by the Indenture Trustee are quoting on the relevant LIBOR
     Determination Date to the principal London offices of leading banks in the
     London interbank market or, in the event that the Indenture Trustee can
     determine no such arithmetic mean, (ii) the lowest one-month U.S. dollar
     lending rate which New York City banks selected by the Indenture Trustee
     are quoting on such LIBOR Determination Date to leading European banks.
 
     Listed below are monthly One-Month LIBOR rates on the last day of the
related calendar month beginning in 1995, as published by Bloomberg. The
following does not purport to be a prediction of the performance of One-Month
LIBOR in the future.

PAYMENTS ON THE NOTES
 
     For the definitions of certain of the defined terms used in the following
subsections, see "--Related Definitions" below.
 
     Available Collection Amount.  Payments on the Notes on each Payment Date
will be made from the Available Collection Amount. The Servicer will calculate
the Available Collection Amount on the 18th calendar day of each month or, if
such day is not a Business Day, then the immediately preceding Business Day
(each such day, a "Determination Date"). With respect to each Payment Date, the
"Available Collection Amount" is the sum of (1) all amounts received on the
Loans or required to be paid by the Master Servicer, the Servicer or the
Transferor during the related Due Period; or with respect to prepayments and
other unscheduled principal payments during the related Due Period (exclusive of
amounts not required to be deposited by the Servicer in the Collection Account
and amounts permitted to be withdrawn by the Indenture Trustee from the
Collection Account); (2) the Purchase Price paid for any Loans required to be
repurchased and the Substitution Adjustment to be deposited in the Collection
Account in connection with any substitution, in each case before the related
Determination Date; and (3) upon the exercise of an optional redemption by the
Majority Residual Interest Certificateholders, the Servicer or the Securities
Insurer, the Termination Price.
 
     On each Payment Date, the "Available Payment Amount" will equal the related
Available Collection Amount deposited into the Note Payment Account and
remaining after providing for the payment of all Issuer Fees and Expenses for
such Payment Date. On each Payment Date, interest and principal payments on the
Notes will be made from the Available Payment Amount and any Insured Payments
for such Payment Date. If for any Payment Date the Securities Insurer is
required to make an Insured Payment, the Indenture Trustee must make a claim for
such Insured Payment under the Guaranty Policy by submitting the required notice
no later than 12:00 noon, New York time, on the second Business Day preceding
such date. See "Description of Credit Enhancement--Financial Guaranty Insurance
Policy" in this prospectus supplement.
 
     Payments of Interest.  Interest on the Note Principal Balance will accrue
thereon during each Accrual Period at the Note Interest Rate, and will be
payable to the holders of the Notes monthly on each Payment Date, commencing in
April 1999.
 
     On each Payment Date, interest payments on the Notes will be made from the
Available Payment Amount and any Insured Payments for such Payment Date. Under
certain circumstances, and in the event of a Securities Insurer Default, the
amount available for interest payments could be less than the amount of interest
payable on the Notes on any Payment Date. In such event, each Note will receive
its ratable share (based upon the aggregate amount of interest due to the Notes)
of the remaining amount available to be paid as interest. In addition, any such
interest deficiency will be carried forward as a Noteholders' Interest Shortfall
Amount, and will be paid to holders of the Notes on subsequent Payment Dates to
the extent that sufficient funds are available. Any such interest deficiency
could occur, for example, if delinquencies or losses realized on the Loans were
exceptionally high or were concentrated in a particular month and Insured
Payments were not timely received under the Guaranty Policy. No interest will
accrue on any Noteholders' Interest Shortfall Amount.
 
     Payments of Principal.  Principal payments will be made to the holders of
the Notes on each Payment Date in an amount described under "--Priority of
Payments" below. The aggregate payments of principal to the Notes will not
exceed the Original Note Principal Balance.
 
PRIORITY OF PAYMENTS
 
     A. On each Payment Date, the Regular Payment Amount and any Insured
Payments will be paid in the following order of priority:
 
          first, to the holders of the Notes, the applicable portion of the
     Noteholders' Interest Payment Amount required to be paid in respect of the
     Notes;
 
          second, to pay principal of the Notes, until the Note Principal
     Balance is reduced to zero, in an amount up to the sum of the Regular
     Principal Payment Amount and the Noteholders' Principal Deficiency Amount,
     if any; and
 
                                      S-47
<PAGE>
          third, any remaining amount to be applied together with Excess Spread
     in the manner specified in paragraph B below.
 
     B. On each Payment Date, the Excess Spread, if any, will be applied in the
following order of priority:
 
          first, to pay the Securities Insurer the Securities Insurer
     Reimbursement Amount, if any;
 
          second, in an amount up to the Overcollateralization Deficiency
     Amount, if any, to pay principal of the Notes, until the Note Principal
     Balance is reduced to zero;
 
          third, to the holders of the Notes, pro rata, Noteholders' Interest
     Carry-Forward Amount due and unpaid, if any; and
 
          fourth, any remaining amount (A) first, concurrently, to the Servicer
     in an amount needed to reimburse any non-recoverable Servicing Advances,
     and to the Master Servicer in an amount needed to reimburse any
     non-recoverable Monthly Advances, and (B) then to the Residual Interest
     Certificates.
 
RELATED DEFINITIONS

          Accrual Period:  The period from and including the immediately
     preceding Payment Date (or, in the case of the first Payment Date, from the

     elapsed in the Accrual Period in a 360-day year.
 
          Business Day:  Any day other than (i) a Saturday or a Sunday or
     (ii) a day on which banking institutions in the City of New York or in the
     city in which the corporate trust office of the Indenture Trustee is
     located or in the city in which the Servicer's servicing operations or the

     the Servicer in connection with the collection of such proceeds and not
     otherwise reimbursed the Servicer, but excluding Insured Payments, the
     proceeds of any insurance policy that are to be applied to the restoration
     or repair of the Mortgaged Property or released to the borrower in
     accordance with the accepted servicing procedures.
 
          Liquidated Loan:  Any Loan in respect of which a monthly payment is in
     excess of 30 days past due and as to which the Servicer has determined that
     all recoverable liquidation and insurance proceeds have been received,
     which will be deemed to occur upon the earliest of: (1) the liquidation of
     the related Mortgaged Property acquired through foreclosure or similar
     proceedings or (2) the Servicer's determination in accordance with the
     accepted servicing procedures that there is not a reasonable likelihood of
     an economically significant recovery from the borrower or the related
     Mortgaged Property in excess of the costs and expenses in obtaining such
     recovery and in relation to the expected timing of such recovery.
 
          Net Liquidation Proceeds:  With respect to any Payment Date, any cash
     amounts received from Liquidated Home Loans, whether through trustee's

     and any other cash amounts received in connection with the management of
     the Mortgaged Properties from defaulted Loans, in each case, net of any
     reimbursements to the Servicer or the Master Servicer, as applicable, made
     from such amounts for any unreimbursed Servicing Compensation, Master
     Servicer Compensation, Servicing Advances and Monthly Advances, as
     applicable, and any other fees and expenses paid in connection with the
     foreclosure, conservation and liquidation of the related Liquidated Home

     holders of the Notes on or before such preceding Payment Date.
 
          Overcollateralization Amount:  With respect to any Payment Date, the
     amount equal to the excess, if any, of (i) the Pool Principal Balance as of

     Amount over the Overcollateralization Amount.
 
          Overcollateralization Reduction Amount:  With respect to any Payment
     Date that occurs on or after the Stepdown Date, the lesser of (1) the
     excess, if any, of (a) the Overcollateralization Amount (assuming principal
     payments of the Notes on such Payment Date are equal to the Regular

     Reduction Amount), over (b) the Overcollateralization Target Amount and
     (2) the Regular Principal Payment Amount (as determined without the

     lien of the related Mortgage, whether by partial condemnation, sale or
     otherwise, which proceeds are not released to the borrower in accordance
     with applicable law, accepted servicing procedures and the Sale and Master
     Servicing Agreement.
 
          Stepdown Date:  The first Payment Date occurring on the later of:
     (a) April 25, 2001; or (b) the Payment Date on which the Pool Principal
     Balance as of the end of the related Due Period has been reduced to 50% of
     the Cut-Off Date Pool Principal Balance.
 
SECURITIES INSURER REIMBURSEMENT AMOUNT
 
     On each Payment Date, after the holders of the Notes have been paid all
amounts, other than the Overcollateralization Deficiency Amount and the
Noteholders' Interest Carry-Forward Amount, to which they are entitled and prior
to any distributions to the holders of the Residual Interest Certificates, the
Securities Insurer will be entitled to be reimbursed for any unreimbursed
Insured Payments in respect of the Notes not previously reimbursed and any other
amounts owed to the Securities Insurer under the Insurance Agreement (including
legal fees and other expenses incurred by the Securities Insurer) together with
interest thereon at the rate specified in the Insurance Agreement (the
"Securities Insurer Reimbursement Amount") and any accrued and unpaid Guaranty
Insurance Premiums. The "Insurance Agreement" means the Insurance and Indemnity
Agreement among the Securities Insurer, the Depositor, Fremont and the Issuer.
In connection with each Insured Payment, the Indenture Trustee, as
attorney-in-fact for the holder thereof, will be required to assign to the
Securities Insurer the rights of the holders of the Notes with respect to the
Notes, to the extent of such Insured Payments, including, without limitation, in
respect of any amounts due to the holders of the Notes as a result of a
securities law violation arising from the offer and sale of the Notes. In the
event that any Securities Insurer Reimbursement Amount is outstanding, the
holders of the Residual Interest Certificates will not be entitled to receive
distributions of any amounts of Excess Spread until the Securities Insurer has
been distributed such Securities Insurer Reimbursement Amount in full.
 
OPTIONAL REDEMPTION
 
     The holders of an aggregate percentage interest in the Residual Interest
Certificates in excess of 50% (the "Majority Residual Interest
Certificateholders") may, at their option, cause the Issuer to effect an early
redemption of the Notes on or after any Payment Date on which the Pool Principal
Balance declines to 10% or less of the Cut-Off Date Pool Principal Balance, by
purchasing all of the Loans from the Owner Trust at a price equal to or greater
than the Termination Price. The "Termination Price" shall be an amount equal to
the greater of (a) the sum of (i) the then outstanding Note Principal Balance
and all accrued and unpaid interest thereon at the Note Interest Rate determined
pursuant to clause (i) of the definition thereof and all unpaid Noteholders'
Interest Carry-Forward Amounts through the last day of the Accrual Period
relating to such Payment Date; (ii) any Issuer Fees and Expenses due and unpaid
on such date; (iii) any unreimbursed Servicing Advances and unreimbursed Monthly
Advances including such advances deemed to be nonrecoverable; and (iv) any
unpaid Securities Insurer Reimbursement Amount and (b) the sum of (i) the
Principal Balance of each Loan included in the Owner Trust as of the close of
business on the first day of the month of such Payment Date; (ii) all unpaid
interest accrued on the Principal Balance of each such Loan at the related
interest rate to such date; (iii) the aggregate fair market value of each
foreclosure property included in the Owner Trust on such date, as determined by
an independent appraiser acceptable to the Indenture Trustee as of a date not
more than 30 days before such date; and (iv) any unpaid Securities Insurer
Reimbursement Amount. The proceeds from such sale will be paid (1) first, to the
outstanding Issuer Fees and Expenses, (2) second, to the Servicer for
unreimbursed Servicing Advances and to the Master Servicer for unreimbursed
Monthly Advances, including such advances deemed to
 
                                      S-50
<PAGE>
be nonrecoverable, (3) third, to the holders of Notes in an amount equal to the
then outstanding Note Principal Balance of the Notes plus all accrued and unpaid
interest thereon at the Note Interest Rate determined pursuant to clause (i) of
the definition of Note Interest Rate and all unpaid Noteholder's Interest
Carry-Forward Amounts, (4) fourth, to the Securities Insurer the Securities
Insurer Reimbursement Amount, if any, and (5) fifth, to the holders of the
Residual Interest Certificates, in an amount equal to the amount of proceeds
remaining, if any, after the payments specified in clauses (1) through
(4) above.
 
     On or after any Payment Date the Pool Principal Balance declines to 5% or
less of the Cut-Off Date Pool Principal Balance, the Securities Insurer or the
Servicer may, at each one's option, cause the Issuer to effect an early
redemption of the Notes if the Majority Residual Interest Certificateholders
fail to exercise their option to cause to the Issuer to effect an early
redemption.
 
     In addition, if certain events of default of the Issuer occur as set forth
in the Indenture, including (a) a default in payment of any interest or
principal amounts due the holders of the Notes, (b) the failure by the Issuer to
observe or perform in any material respect any of its covenants or agreements in
the Indenture, which failure continues unremedied for 30 days, and (c) certain
events of bankruptcy, insolvency or other similar proceedings relating to the
Issuer, then the Securities Insurer may, at its option, effect an early
redemption of the Notes, by purchasing all of the Loans from the Owner Trustee
at a price equal to the Termination Price.
 
                       DESCRIPTION OF CREDIT ENHANCEMENT
 
     Credit enhancement with respect to the Notes will be provided by the
Guaranty Policy. Additional credit enhancement with respect to the Notes that
will be utilized before the Guaranty Policy will be provided by (i) the
overcollateralization feature described below under "--Overcollateralization,"
and (ii) the subordination of the right of the Residual Interest Certificates to
receive payments of any remaining amounts as described below under
"--Subordination."
 
FINANCIAL GUARANTY INSURANCE POLICY
 
     The following summary of the terms of the Financial Guaranty Insurance
Policy (the "Guaranty Policy") does not purport to be complete and is qualified
in its entirety by reference to the Policy, which will be filed under cover of
Form 8-K shortly after the Closing Date.
 
     Simultaneously with the issuance of the Notes, the Securities Insurer will
deliver the Guaranty Policy to the Indenture Trustee for the benefit of each
Noteholder. Under the Guaranty Policy, the Securities Insurer unconditionally
and irrevocably guarantees to the Indenture Trustee for the benefit of each
holder of the Notes the full and complete payment of (i) Insured Payments (as
defined below) on the Notes; and (ii) the amount of any Insured Payment which
subsequently is avoided in whole or in part as a preference payment under
applicable law.
 
     "Insured Payments" means, on any Payment Date the sum of any insufficiency
resulting from the Available Payment Amount being less than the accrued and
unpaid interest due on the Notes (less Noteholders' Interest Carry-Forward
Amounts and Relief Act shortfalls), and any Noteholders' Principal Deficiency
Amount.
 
     Noteholders' Principal Deficiency Amount:  (1) With respect to any Payment
Date (other than as set forth in clause (2) below), the excess, if any, of
(a) the Note Principal Balance as of such Payment Date (after giving effect to
all payments of principal on the Notes on such Payment Date, but without giving
effect to payments in respect of the Noteholders' Principal Deficiency Amount to
be made on such Payment Date), over (b) the Pool Principal Balance as of the end
of the related Due Period and (2) with respect to the Maturity Date of the
Notes, the excess of (a) the Note Principal Balance (after giving effect to all
payments of principal on the Notes on such date, but without giving effect to
payments in respect of this Noteholders' Principal Deficiency Amount to be made
on such date) over (b) the Available Payment Amount remaining after the payment
of the Noteholders' Interest Payment Amount and Regular Principal Payment Amount
for such date.
 
     Payment of claims on the Guaranty Policy made in respect of Insured
Payments will be made by the Securities Insurer following Receipt by the
Securities Insurer of the appropriate notice for payment on the later to occur
of (i) 12:00 noon, New York City time, on the second Business Day following
Receipt of such notice for payment, and (ii) 12:00 noon, New York City time, on
the date on which such payment was due on the Notes.

     If payment of any amount avoided as a preference under applicable
bankruptcy, insolvency, receivership or similar law is required to be made under
the Guaranty Policy, the Securities Insurer shall cause such payment to be made
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 Securities Insurer from the Indenture Trustee of (A) a certified
copy of the order (the "Order") of the court or other governmental body which
exercised jurisdiction to the effect that the Noteholder is required to return
principal or interest paid on the Notes during the term of the Guaranty Policy
because such payments were avoidable as preference payments under applicable
bankruptcy law, (B) a certificate of the Noteholder that the Order has been
entered and is not subject to any stay, and (C) an assignment duly executed and
delivered by the Noteholder, in such form as is reasonably required by the
Securities Insurer and provided to the Noteholder by the Securities Insurer,
irrevocably assigning to the Securities Insurer all rights and claims of the
Noteholder relating to or arising under the Notes against the Issuer or
otherwise with respect to such preference payment, or (ii) the date of Receipt
by the Securities Insurer from the Indenture Trustee of the items referred to in
clauses (A), (B) and (C) above if, at least four Business Days prior to such
date of Receipt, the Securities Insurer shall have Received written notice from
the Indenture 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 Indenture Trustee or any Noteholder directly (unless a
Noteholder 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 Indenture Trustee for distribution to
such Noteholder upon proof of such payment reasonably satisfactory to the
Securities Insurer). In connection with the foregoing, the Securities Insurer
shall have the rights provided pursuant to the Indenture.
 
     The terms "Receipt" and "Received", with respect to the Guaranty Policy,
shall mean actual delivery to the Securities Insurer or its fiscal agent, if
any, prior to 12:00 noon, New York City time, on a Business Day; delivery either
on a day that is not a Business Day or after 12:00 noon, New York City time,
shall be deemed to be Receipt on the next succeeding Business Day. If any notice
or certificate given under the Guaranty Policy by the Indenture 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 Securities Insurer, or its fiscal
agent, if any, shall promptly so advise the Indenture Trustee and the Indenture
Trustee may submit an amended notice.
 
     Under the Guaranty 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 city in which the corporate trust office of the
Indenture Trustee is located or in the city in which the Servicer's servicing
operations or the Master Servicer's master servicing operations are primarily
located and are authorized or obligated by law or executive order to be closed.
 
     The Securities Insurer's obligations under the Guaranty Policy in respect
of Insured Payments shall be discharged to the extent funds are transferred to
the Indenture Trustee as provided in the Guaranty Policy whether or not such
funds are properly applied by the Indenture Trustee.
 
     The Securities Insurer shall be subrogated to the rights of each Noteholder
to receive payments of principal and interest under the Notes to the extent of
any payment by the Securities Insurer under the Guaranty Policy. For a
discussion of the rights and powers of the Securities Insurer upon an event of
default under the Transfer and Servicing Agreements, see "Description of the
Transfer and Servicing Agreements" in this prospectus supplement.
 
     To the fullest extent permitted by applicable law, the Securities Insurer
agrees under the Guaranty Policy not to assert, and waives, for the benefit of
each Noteholder, 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 Securities Insurer to avoid payment of its
obligations under the Guaranty Policy in accordance with the express provisions
of the Guaranty Policy.
 
     Claims under the Guaranty Policy constitute direct, unsecured and
unsubordinated obligations of the Securities Insurer ranking not less than pari
passu with other unsecured and unsubordinated indebtedness of the Securities
Insurer for borrowed money. Claims against the Securities Insurer under the
Guaranty Policy and claims against the Securities Insurer under each other
financial guaranty insurance policy issued thereby
 
                                      S-52
<PAGE>
constitute pari passu claims against the general assets of the Securities
Insurer. The terms of the Guaranty Policy cannot be modified or altered by any
other agreement or instrument, or by the merger, consolidation or dissolution of
the Issuer. The Guaranty Policy may not be cancelled or revoked prior to payment
in full of the Notes. The Guaranty Policy is not covered by the
property/casualty insurance security fund specified in Article 76 of the New
York Insurance Law. The Guaranty Policy is not covered by the Florida Insurance
Guaranty Association created under Part II of Chapter 631 of the Florida
Insurance Code. In the event the Securities Insurer were to become insolvent,
any claims arising under the Guaranty Policy are excluded from coverage by the
California Insurance Guaranty Association, established pursuant to Article 14.2
of Chapter 1 of Part 2 of Division 1 of the California Insurance Code. The
Guaranty Policy is governed by the laws of the State of New York.
 
THE SECURITIES INSURER
 
     The information set forth below under "The Securities Insurer" has been
supplied by Financial Security Assurance Inc., as the Securities Insurer, for
inclusion in this prospectus supplement and has not been reviewed or verified by
Fremont, the Servicer, the Depositor, the Indenture Trustee, the Owner Trustee,
the Underwriters or any of their respective affiliates.
 
     General.  The Securities Insurer is a monoline insurance company
incorporated in 1984 under the laws of the State of New York. The Securities
Insurer is licensed to engage in the financial guaranty insurance business in
all 50 states, the District of Columbia and Puerto Rico.
 
     The Securities Insurer 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. The Securities
Insurer 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. The Securities Insurer insures both newly issued securities sold in
the primary market and outstanding securities sold in the secondary market that
satisfy the Securities Insurer's underwriting criteria.
 
     The Securities Insurer 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 the
Securities Insurer or any claim under any insurance policy issued by the
Securities Insurer or to make any additional contribution to the capital of the
Securities Insurer.
 
     The principal executive offices of the Securities Insurer 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 the
Securities Insurer or 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, the
Securities Insurer 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 the Securities Insurer as a risk management device and to comply with
statutory and rating agency requirements; it does not alter or limit the
Securities Insurer's obligations under any financial guaranty insurance policy.
 
     Ratings.  The Securities Insurer's insurance financial strength is rated
"Aaa" by Moody's Investors Service, Inc. The Securities Insurer's insurer
financial strength is rated "AAA" by Standard & Poor's Ratings Services, A
Division of The McGraw-Hill Companies, Inc., and Standard & Poor's (Australia)
Pty. Ltd. The Securities Insurer's claims-paying ability is rated "AAA" by Fitch
IBCA, Inc. and Japan Rating and Investment

     The Securities 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 Securities 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
Securities 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 policy holders, establishes contingency, loss and unearned
premium reserve requirements for each such insurer, and limits the size of
individual transactions and the volume of transactions 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 Securities 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.
 
OVERCOLLATERALIZATION
 
     A limited acceleration of the principal amortization of the Notes relative
to the principal amortization of the Loans has been designed to increase the
Overcollateralization Amount over time by making additional payments of
principal to the holders of the Notes from the payment of Excess Spread until
the Overcollateralization Amount is equal to the Overcollateralization Target
Amount.
 
     If on any Payment Date there exists an Overcollateralization Deficiency
Amount, payments of Excess Spread, if any, will be made as an additional payment
of principal to the holders of the Notes as set forth under "Description of the
Notes--Priority of Payments" in this prospectus supplement. Such payments of
Excess Spread are intended to accelerate the amortization of the Note Principal
Balance relative to the amortization of the Loans, thereby increasing the
Overcollateralization Amount. The relative percentage of the Note Principal
Balance to the Pool Principal Balance will decrease as a result of the
application of Excess Spread to reduce the Note Principal Balance.
 
     On any Payment Date with respect to which the Overcollateralization
Deficiency Amount is equal to zero, all or a portion of the Excess Spread may be
distributed to the holders of the Residual Interest Certificates as described in
this prospectus supplement rather than being paid as principal to the holders of
the applicable Notes. This would have the effect of ceasing the acceleration of
principal amortization of such Notes in relation to the principal amortization
of the Pool until such time as the Overcollateralization Deficiency Amount is
greater than zero (i.e., due to a reduction in the Overcollateralization Amount
as a result of Realized Losses or delinquencies or due to an increase in the
Overcollateralization Target Amount as a result of the failure to satisfy
certain delinquency or loss criteria).
 
     On any Payment Date occurring on or after a Stepdown Date or the date on
which the Securities Insurer has reduced the Overcollateralization Target
Amount, the holders of the Residual Interest Certificates may receive payments,
to the extent of the Overcollateralization Reduction Amount, attributable to all
or a portion of the Regular Principal Payment Amount that would otherwise be
paid to the holders of the Notes.
 
     The Overcollateralization Target Amount may decrease or "stepdown" (1) as a
result of the performance of the Loans with respect to the principal
amortization of the Loans declining to certain levels and the delinquency and
default experience of the Loans staying lower than certain levels established by
the Securities Insurer, and (2) if following an increase in the rates of
delinquencies and defaults on the Loans, such rates improve in relation to the
levels established by the Securities Insurer. Pursuant to the Sale and Master
Servicing Agreement, the Securities Insurer may modify, without the requirement
of an amendment to the Sale and Master Servicing
 
                                      S-55
<PAGE>
Agreement, the manner in which the Overcollateralization Target Amount is
determined such that the Overcollateralization Target Amount is decreased at any
time in the discretion of the Securities Insurer, but not below the amounts set
forth below.
 
     While the application of Excess Spread in the manner specified above has
been designed to produce and maintain a given level of overcollateralization,
there can be no assurance that Excess Spread will be generated in sufficient
amounts to ensure that such overcollateralization level will be achieved or
maintained at all times. In particular, a high rate of delinquencies on the
Loans during any Due Period could cause the amount of interest received on the
Loans during such Due Period to be less than the amount of interest payable on
the Notes on the related Payment Date. In such a case, the Note Principal
Balance could decrease at a slower rate relative to the Pool Principal Balance,
resulting in a possible reduction of the Overcollateralization Amount. In
addition, Realized Losses from Liquidated Loans and Defaulted Loans will reduce
the Pool Principal Balance, which in turn will reduce the Overcollateralization
Amount. See "Risk Factors--Adequacy of Credit Enhancement" in this prospectus
supplement.
 
     RELATED DEFINITIONS.  For purposes of this prospectus supplement, the
following terms shall have the following meanings:
 
          "Overcollateralization Target Amount":  With respect to any Payment
     Date, an amount determined as follows:
 
          (1) with respect to any Payment Date occurring prior to the Stepdown
     Date, the amount equal to 4.00% of the Cut-Off Date Pool Principal Balance;
 
          (2) with respect to any other Payment Date occurring on or after the
     Stepdown Date, an amount equal to the greatest of (a) an amount that may
     stepdown over a period generally equal to six months to not less than 8.00%
     of the Pool Principal Balance as of the end of the related Due Period based
     on the formula set forth in the Transfer and Servicing Agreements,
     (b) 0.50% of the Cut-Off Date Pool Principal Balance and (c) an amount
     equal to the aggregate Principal Balance of the three largest Loans then
     outstanding; and
 
          (3) with respect to any Payment Date occurring on or after an OC
     Trigger Increase Event, notwithstanding any of the preceding clauses (1)
     through (2), an amount equal to 100% of the Cut-Off Date Pool Principal
     Balance; provided, however, that with respect to any Payment Date occurring
     on or after an OC Trigger Reversal Event, an amount determined pursuant to
     clause (1) or (2) above, as applicable;
 
provided, however, with respect to any Payment Date, notwithstanding the
preceding clauses (1) through (3), the Overcollateralization Target Amount shall
not exceed the Note Principal Balance. The Overcollateralization Target Amount
will be subject to certain stepups and stepdowns based on certain delinquency
and loss tests and excess spread requirements with respect to the Loans. The
Securities Insurer may reduce the Overcollateralization Target Amount, at any
time to, but not below, (1) with respect to any Payment Date occurring prior to
the Stepdown Date, 2.00% of the Cut-Off Date Pool Principal Balance or (2) with
respect to any Payment Date occurring on or after the Stepdown Date, an amount
equal to the greater of (a) 4.00% of the Pool Principal Balance as of the end of
the related Due Period, (b) 0.50% of the Cut-Off Date Pool Principal Balance or
(c) an amount equal to the aggregate Principal Balance of the three largest
Loans then outstanding.
 
     "OC Trigger Increase Event" and "OC Trigger Reversal Event"  are defined in
the Transfer and Servicing Agreements and are based on excess spread
requirements and delinquency and loss levels established by the Securities
Insurer. The Securities Insurer may change these delinquency and loss levels at
any time.
 
SUBORDINATION
 
     Payments of interest will be made first to the Notes. The rights of the
holders of the Residual Interest Certificate to receive any payments on any
Payment Date will be subordinated to the rights of the holders of the Notes.
This subordination of the Residual Interest Certificates is intended to enhance
the likelihood of the regular receipt of interest and principal due to the
holders of the Notes and to afford such holders protection against losses on the
Loans. See "Risk Factors--Adequacy of Credit Enhancement" in this prospectus
supplement.

SALE AND ASSIGNMENT OF THE LOANS
 
     On the Closing Date, all of the Transferor's right, title and interest in
and to the Loans will be sold, conveyed, transferred and assigned from the
Transferor to the Depositor and then from the Depositor to the Issuer. The
Issuer, concurrently with the sale, conveyance, transfer and assignment of the
Loans, will cause the Notes and the Residual Interest Certificates to be
delivered to the Depositor in exchange for the Loans. The Issuer will pledge and
assign the Loans to the Indenture Trustee in exchange for the Notes.
 
     In addition, the Transferor will, as to each Loan, deliver or cause to be
delivered, to the Custodian, the related note endorsed in blank or to the order
of the Indenture Trustee without recourse, any assumption and modification
agreements and the mortgage, deed of trust, or other similar security
instruments (the "Mortgage"), with evidence of recording indicated thereon
(except for any Mortgage not returned from the public recording office), an
assignment of the Mortgage, if any, in the name of the Indenture Trustee in
recordable form, a title insurance policy and any intervening assignments of the
Mortgage (collectively, as to each Loan, the "Indenture Trustee's Loan File").
Subject to the confirmation by the Rating Agencies and to the approval of the
Securities Insurer, with respect to the Loans secured by Mortgaged Properties
located in certain states, the Transferor will not be required to record
assignments of the Mortgages to the Indenture Trustee in the real property
records of such states. In such circumstances, the Transferor will deliver to
the Custodian the assignments of the Mortgages in the name of the Indenture
Trustee and in recordable form, and the Transferor, in its capacity as the
Master Servicer, will retain the record title to such Mortgages under the
applicable real property records, on behalf of the Issuer, the Indenture Trustee
and the Security Owners. In all other circumstances, pursuant to the direction
of the Rating Agencies or the Securities Insurer, assignments of the Mortgages
to the Indenture Trustee will be recorded in the real property records for those
states in which such recording is deemed necessary to protect the Indenture
Trustee's interest in the Loans against the claims of certain creditors of the
Transferor or subsequent purchasers. In these circumstances, the Transferor will
deliver to the Custodian after recordation the assignments of the Mortgages in
the name of the Indenture Trustee. The Custodian will agree, for the benefit of
the holders of the Notes, to review (or cause to be reviewed) each Indenture
Trustee's Loan File delivered to it within 45 days after the pledge of the
related Loan to the Indenture Trustee to ascertain that all required documents
have been executed and received. Subject to certain cure provisions set forth in
the Transfer and Servicing Agreements, the Transferor will be required to
repurchase or replace Loans as to which a material document deficiency exists.
 
     Although the recordation of the assignments of the Mortgages in favor of
the Indenture Trustee is not necessary to effect a pledge of the Loans to the
Indenture Trustee, if the Transferor or the Depositor were to sell, assign,
satisfy or discharge any Loan prior to recording the related assignment in favor
of the Indenture Trustee, the other parties to such sale, assignment,
satisfaction or discharge may have rights superior to those of the Indenture
Trustee. In some states, in the absence of such recordation of the assignments
of the Mortgages, the transfer to the Indenture Trustee of the Loans may not be
effective against certain creditors or purchasers from the Transferor or a
trustee in bankruptcy of the Transferor. If such other parties, creditors or
purchasers have rights to the Loans that are superior to those of the Indenture
Trustee, the holders of the Notes could lose the right to future payments of
principal and interest from such Loans and could suffer a loss of principal and
interest to the extent that such loss is not otherwise covered by the applicable
credit enhancement. See "Risk Factors--Adequacy of Credit Enhancement" in this
prospectus supplement.

<PAGE>
REPRESENTATIONS AND WARRANTIES
 
     In the Sale and Master Servicing Agreement, the Transferor will represent
and warrant to the Issuer and Indenture Trustee, among other things, that:
(i) the information with respect to each Loan set forth in the schedule
appearing as an exhibit to the Sale and Master Servicing Agreement delivered to
the Issuer (the "Loan Schedule") is true and correct in all material respects;
(ii) upon the sale to the Depositor of each Loan, the Depositor will have good
and indefeasible legal title to each Loan, the related note and any related
mortgage, free of all liens, pledges, charges, mortgages, encumbrances or rights
of others; (iii) as of the Cut-Off Date, no more than approximately 3.77% of the
Loans were 30 days or more past due; no more than approximately 0.13% of the
Loans were 60 or more days past due; and none of the Loans were more than
89 days past due; and (iv) at origination, each Loan complied in all material
respects with applicable state and federal laws.
 
REPURCHASE OF LOANS
 
     The Transferor will have a limited option after the Closing Date to
repurchase any Loan incident to foreclosure (a "Defaulted Loan"). Each purchase
of a Defaulted Loan will be conducted in the same manner as a repurchase of a
Defective Loan as described below. The Transferor will also be obligated either
to repurchase any Defective Loan or to remove such Defective Loan and substitute
a Qualified Substitute Loan. The repurchase of any Loan (rather than the
replacement of the Loan through substitution) will result in accelerated
principal payments on the Notes.
 
     Unless waived by the Securities Insurer, the Transferor is required (a)
within 60 days after discovery or notice thereof to cure in all material
respects any breach of the representations or warranties which materially and
adversely affects the value of a Loan or the interests of the Owner Trustee, the
Securities Insurer or the Indenture Trustee or as to which a material document
deficiency exists (each, a "Defective Loan") or (b) on or before the
Determination Date next succeeding the end of such 60 day period, to repurchase
such Defective Loan at a price (the "Purchase Price") equal to the Principal
Balance of such Defective Loan as of the date of repurchase, plus all accrued
and unpaid interest on such Defective Loan from the Closing Date to but not
including the date of repurchase computed at the Loan Rate, plus the amount of
any unreimbursed Servicing Advances and Monthly Advances made by the Servicer
and Master Servicer, respectively, with respect to such Defective Loan. In lieu
of repurchasing a Defective Loan, the Transferor may replace such Defective Loan
with one or more Qualified Substitute Loans within two years of the Closing
Date. If the aggregate outstanding principal balance plus all accrued and unpaid
interest of the Qualified Substitute Loan(s) is less than the outstanding
Principal Balance of the Defective Loan(s) plus all accrued and unpaid interest,
the Transferor will also remit for payment to the holders of the Notes an amount
(a "Substitution Adjustment") equal to such shortfall which will result in a
prepayment of principal on the Notes for the amount of such shortfall. As used
in this prospectus supplement, a "Qualified Substitute Loan" means a loan that
(1) has an interest rate which differs from the Loan Rate for the Defective Loan
which it replaces (each a "Deleted Loan") by no more than two percentage points
in excess of such Loan Rate and no lower than the interest rate of the Deleted
Loan, and pays interest in the same manner as the Deleted Loan (i.e., fixed-rate
or adjustable-rate), (2) matures not more than one year later than, and not more
than one year earlier than, the maturity date of the Deleted Loan, and in any
case not later than March 1, 2029, (3) has a principal balance (after
application of all payments received on or before the date of such substitution)
equal to or less than the principal balance of the Deleted Loan as of such date,
(4) has a lien priority no lower than the Deleted Loan, (5) complies as of the
date of substitution with each representation and warranty set forth in the Sale
and Master Servicing Agreement with respect to the Loans and is not more than 89
days delinquent as of the date of substitution for such Deleted Loan, (6) has a
borrower with a debt-to-income ratio no higher than the debt-to-income ratio of
the borrower with respect to the Deleted Loan, and (7) is otherwise acceptable
to the Securities Insurer provided that with respect to a substitution of
multiple loans, items (1), (2) and (3) above may be considered on an aggregate
or weighted average basis.
 
     At any particular time, the Transferor may not be capable, financially or
otherwise, of repurchasing Defective Loans or substituting Qualified Substitute
Loans for Defective Loans in the manner described above. Events relating to the
Transferor and its operations may occur that would adversely affect the ability
of the Transferor to repurchase or replace Defective Loans, or the sale or other
disposition of all or any significant portion of its assets. If the Transferor
is unable to repurchase or replace a Defective Loan, the Servicer will utilize
other accepted servicing procedures to realize any reasonable recovery of net
proceeds from such Defective Loan.

FEES AND EXPENSES
 
     The fees and expenses for the Series 1999-1 (the "Issuer Fees and
Expenses") consist of the following:
 
          (a) as compensation for its services pursuant to the Sale and Master
     Servicing Agreement and the Servicing Agreement, (1) the Servicer is
     entitled to the Servicing Compensation and reimbursement as described under
     "--Servicing" below, and (2) the Master Servicer is entitled to the Master
     Servicer Compensation as described under the "Master Servicer" in this
     prospectus supplement;
 
          (b) as compensation for its services pursuant to the applicable
     Transfer and Servicing Agreements, the Indenture Trustee is entitled to a
     monthly fee in an amount equal to one twelfth of the product of 0.0065% and
     the Principal Balance of the Loans as of the first day of the immediately
     preceding Due Period (or as of the Cut-Off Date, with respect to the first
     Due Period) (the "Indenture Trustee Fee") and reimbursement of expenses;
 
          (c) as compensation for issuing the Guaranty Policy, the Security
     Insurer is entitled to a premium (the "Guaranty Insurance Premium") to be
     determined based on the outstanding Note Principal Balance.
 
SERVICING
 
     In consideration for the performance of the daily loan servicing functions
for the Loans, the Servicer is entitled to receive a monthly servicing fee (the
"Servicing Fee") as to each Loan in the amount equal to one-twelfth of the
product of 0.35% (the "Servicing Fee Rate") and the Principal Balance of such
Loan as of the first day of the immediately preceding Due Period (or as of the
Cut-Off Date, with respect to the first Due Period). See "--Servicer
Determinations and Events of Defaults" below. The Servicer may subcontract its
servicing obligations pursuant to a subservicing agreement (each such servicer,
in this capacity, a "subservicer"; provided, however, the Servicer will not be
relieved of its servicing obligations and duties with respect to any subserviced
Loans. The Servicer will pay the fees of any Subservicer out of the amounts it
receives as the Servicing Fee. In addition to the Servicing Fee, the Servicer is
entitled to retain additional servicing compensation in the form of assumption,
modification and other administrative fees, insufficient funds charges, and
certain other servicing-related penalties and fees (such additional compensation
and the Servicing Fee, collectively, the "Servicing Compensation").
 
     In the event of a delinquency or default with respect to a Loan, the
Servicer will have no obligation to advance scheduled monthly payments of
principal or interest with respect to such Loan. However, the Master Servicer
will advance Monthly Advances. The Servicer will make reasonable and customary
expense advances with respect to the Loans (each, a "Servicing Advance") in
accordance with accepted servicing procedures. For example, such Servicing
Advances with respect to a Loan may include costs and expenses advanced for the
preservation, restoration and protection of the related Mortgaged Property,
including advances to pay delinquent real estate taxes and assessments, or for
any collection, enforcement or judicial proceedings. The Servicer need not make
such advance if it determines there is no reasonable likelihood of (i)
recovering such Servicing Advance, together with any prior or expected future
Servicing Advances for such Loan, and (ii) recovering an economically
significant amount from the interest and principal owing on such Loan in excess
of the costs and expenses to obtain such recovery. The Servicer will be entitled
to receive reimbursement for such Servicing Advances from the related borrower
or any proceeds realized from the liquidation of the related Loan or Mortgaged
Property. Any Servicing Advances previously made and determined by the Servicer
in accordance with accepted servicing procedures to be nonrecoverable will be
reimbursable from amounts in the Note Payment Account after payments are made to
the holders of the Notes.
 
COLLECTION ACCOUNT, NOTE PAYMENT ACCOUNT AND CERTIFICATE DISTRIBUTION ACCOUNT
 
     The Servicer is required to use its best efforts to deposit in an Eligible
Account (as defined in the Sale and Master Servicing Agreement) (the "Collection
Account"), within one Business Day after receipt, all payments on the related
Loans received after the Cut-Off Date on account of principal and interest, all
Net Liquidation Proceeds, Insurance Proceeds, Released Mortgaged Property
Proceeds, any amounts payable in connection with the repurchase or substitution
of any Loan, interest and gains on funds held in the Collection Account and any
amount required to be deposited in the Collection Account in connection with the
termination of the Notes. The foregoing requirements for deposit in the
Collection Account will be exclusive of payments on account of
 
                                      S-59
<PAGE>
principal and interest collected on the Loans on or before the Cut-Off Date.
Withdrawals will be made from the Collection Account only for the purposes
specified in the Sale and Master Servicing Agreement. The Collection Account may
be maintained at any depository institution, which satisfies the requirements
set forth in the definition of Eligible Account in the Sale and Master Servicing
Agreement.
 
     The Indenture Trustee will establish and maintain an account, in the name
of the Indenture Trustee on behalf of the holders of the Notes, into which
amounts released from the Collection Account in respect of distributions on the
Loans and any proceeds from the Guaranty Policy for payment to the holders of
Notes will be deposited and from which all payments to the holders of the Notes
will be made (the "Note Payment Account"). The Indenture Trustee will also
establish and maintain an account in the name of the Owner Trustee on behalf of
the holders of the Residual Interest Certificates, into which amounts released
from the Collection Account or Note Payment Account for distribution to the
Residual Interest Certificates will be deposited and from which all
distributions to the Residual Interest Certificates will be made (the
"Certificate Distribution Account" and, together with the Note Payment Account,
the "Payment Accounts").
 
     On the fourth Business Day before each Payment Date, the Servicer will
remit to the Indenture Trustee for deposit into the Note Payment Account the
applicable portions of the Available Collection Amount by making the appropriate
withdrawals from the Collection Account in respect of payments on the Loans. On
each Payment Date, the Indenture Trustee will make withdrawals from the Note
Payment Account for application of the amounts specified under "Description of
the Notes--Payments on the Notes" in this prospectus supplement and for deposit
to the Certificate Distribution Account.
 
INCOME FROM ACCOUNTS
 
     So long as no Event of Default will have occurred and is continuing,
amounts on deposit in the Payment Accounts and the Collection Account
(collectively, the "Accounts") will be invested by the Indenture Trustee, as
directed by the Master Servicer in the case of the Collection Account and the
Note Payment Account, in one or more investments permitted under the Sale and
Master Servicing Agreement bearing interest or sold at a discount. No such
investment in any Account will mature later than the Business Day immediately
preceding the next Payment Date. All income or other gain from investments in
the Collection Account and the Note Payment Account will be paid to the Master
Servicer as part of the Master Servicer Compensation. The Master Servicer will
be obligated to reimburse the Collection Account and the Note Payment Account
for any realized investment losses that are incurred in respect of investments
of amounts therein.
 
COLLECTION AND OTHER SERVICING PROCEDURES FOR LOANS
 
     The Servicer has agreed to manage, service, administer and make collections
on the Loans and perform the other actions required by the Servicer under the
Servicing Agreement. In performing such obligations, the Servicer is required to
act in good faith in a commercially reasonable manner and in accordance with the
terms of the Servicing Agreement. The Servicer has full power and authority,
subject only to the specific requirements and prohibitions of the Servicing
Agreement and the respective Loans, to do any and all things in connection with
such servicing and administration which are consistent with its accepted
servicing procedures. Under the Servicing Agreement, the Servicer's "accepted
servicing procedures" shall mean those servicing procedures that (1) meet at
least the same standards the Servicer would follow in exercising reasonable care
in servicing mortgage and consumer loans such as the Loans held for its own
account, (2) comply with applicable state and federal law, (3) comply with the
provisions of the related notes and Mortgages, and (4) give due consideration to
the accepted standards of practice of prudent consumer loan servicers that
service comparable loans and the reliance placed by the holders of the Notes,
the holders of the Residual Interest Certificates and the Securities Insurer on
the Servicer for the servicing of the Loans.
 
     If any payment due under any Loan is not paid when the same becomes due and
payable, or if the related borrower fails to perform any other covenant or
obligation under the Loan and such failure continues beyond any applicable grace
period, the Servicer, in accordance with the accepted servicing procedures, must
take such action as it shall deem to be in the best interest of the Security
Owners. In determining whether to undertake certain servicing actions with
respect to one or more delinquent or defaulted Loans, the Servicer is expected
to consider the reasonable likelihood of (A) recovering an economically
significant amount attributable to the unpaid principal and interest owing on
such Loan as a result of such actions, in excess of (B) the costs and expenses
to
 
                                      S-60
<PAGE>
obtain such recovery (including without limitation any Servicing Advances, and
in relation to (C) the expected timing of such recovery therefrom.
 
INSURANCE
 
     The Servicer is required to cause to be maintained any fire and hazard
insurance with respect to any Mortgaged Property acquired by the Owner Trustee
in foreclosure.
 
REALIZATION UPON DEFAULTED LOANS
 
     Subject to certain limitations in the Sale and Master Servicing Agreement,
the Servicer may modify any provision of any Loan if, in the Servicer's good
faith judgment, such modification would minimize the loss that might otherwise
be experienced with respect to such Loan, only in the event of a payment default
with respect to such Loan or if a payment default with respect to such Loan is
reasonably foreseeable by the Servicer. For example, the Servicer must obtain
the prior consent of the Securities Insurer to effect modifications,
substitutions of collateral, or dispositions of Loans through short sales or
short pay-offs, if the aggregate of the principal balances of such modified
Loans exceeds 1% of the Cut-Off Date Principal Balance of the Loans.
 
     With respect to any Loan in default and subject to the prior written
consent of the Securities Insurer and the Master Servicer, the Servicer may,
among other things, accept short pay-offs or short sales, enter into assumptions
and modifications, refer to a collection agency or attorney, pursue collection
litigation or alternative court proceedings to foreclosure actions, sell such
Loan to another person, institute foreclosure proceedings, exercise any power of
sale to the extent permitted by law, obtain a deed in lieu of foreclosure, or
otherwise acquire possession of or title to any Mortgaged Property, by operation
of law or otherwise. The Servicer will be acting in the best interests of the
holders of the Notes, when the Servicer, in accordance with the accepted
servicing procedures, undertakes actions to collect a defaulted Loan that have a
higher likelihood of a reasonable recovery within a shorter time period, and
foregoes taking actions that have a lower likelihood of a larger recovery over a
longer time period. See "Risk Factors--Realization Upon Defaulted Loans" in this
prospectus supplement. Subject to the prior consent of the Securities Insurer,
the Servicer may, in a manner consistent with the accepted servicing procedures,
permit a borrower who is selling his principal residence and relocating to
another location, to substitute as collateral for the related Loan the
borrower's new single family residence in place of the Mortgaged Property being
sold or any other real or personal property of the borrower, which may include
an interim substitution of personal property pending the borrower's acquisition
of a new residence. Under certain circumstances, if such borrower has received
net proceeds from the sale of the prior residence that will not be applied to
the purchase of the new residence, then the Servicer, in its discretion, may
require that such borrower either (i) make a partial prepayment in reduction of
the principal balance of the Loan, or (ii) place such funds into a depository
account or certificate of deposit as collateral for the related Loan. If a
borrower is selling its Mortgaged Property in a distressed situation or a
situation involving compensating factors, then the Servicer, in a manner
consistent with the accepted servicing procedures, may (i) accept a partial
payment for the release of the lien on the Mortgaged Property, which will leave
the related Loan unsecured (i.e., a short sale), or (ii) accept a settlement
involving a partial payment for the release of the lien on the Mortgaged
Property and the cancellation of the Loan, which will result in a net loan loss
from any unpaid principal shortfall (i.e., a short payoff).
 
     In connection with any such foreclosure proceeding, power of sale, deed in
lieu of foreclosure or other acquisition of a Mortgaged Property and any sale or
liquidation of the Loan or related Mortgaged Property, the Servicer shall comply
with the requirements of the Sale and Master Servicing Agreement, including the
requirement that the Servicer follow the accepted servicing procedures for
foreclosure and operation of foreclosed property.
 
EVIDENCE AS TO COMPLIANCE
 
     The Servicing Agreement provides that the Servicer shall deliver to the
Master Servicer, and the Sale and Master Servicing Agreement provides that the
Master Servicer shall provide to the Indenture Trustee, the Issuer, the
Depositor, the Securities Insurer and the Rating Agencies an annual statement
signed by an officer of the Servicer stating that the Servicer has fulfilled its
obligations under the Servicing Agreement throughout the preceding year, except
as specified in such statement.
 
                                      S-61
<PAGE>
     Each year (within 90 days following the end of the Servicer's fiscal year),
beginning in 1999, the Servicer will furnish to the Master Servicer, and the
Master Servicer shall provide to the Indenture Trustee, the Issuer, the Rating
Agencies, the Securities Insurer and the Depositor a report prepared by a firm
of nationally recognized independent public accountants (which may also render
other services to the Servicer) to the effect that such firm has examined
certain documents and the records relating to servicing of the Loans as
specified in the Sale and Master Servicing Agreement and the Servicing Agreement
and such firm's conclusion that the Servicer is in compliance with respect
thereto.
 
     The Servicer's fiscal year begins on July 1 and ends on June 30.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER
 
     The Sale and Master Servicing Agreement provides that the Master Servicer
may not resign from its obligations and duties thereunder except (i) with the
consent of the Owner Trustee, the Securities Insurer and Indenture Trustee or
(ii) upon determination that the performance of its duties under the Sale and
Master Servicing Agreement are no longer permissible under applicable law. Any
such determination permitting the resignation of the Master Servicer pursuant to
clause (ii) of the immediately preceding sentence shall be evidenced by an
opinion of counsel to such effect delivered and acceptable to the Owner Trustee,
the Securities Insurer and the Indenture Trustee. No resignation of the Master
Servicer shall become effective until a successor master servicer acceptable to
the Securities Insurer, the Rating Agencies and the Indenture Trustee shall have
assumed the Master Servicer's responsibilities and obligations.
 
     The Master Servicer has agreed not to merge or consolidate with any other
company or permit any other company to become the successor to the Master
Servicer's business unless, after the merger or consolidation, the successor or
surviving entity shall be an Eligible Servicer (as defined in the Sale and
Master Servicing Agreement) acceptable to the Securities Insurer, and shall be
capable of fulfilling the duties of the Master Servicer contained in the Sale
and Master Servicing Agreement. Any company into which the Master Servicer may
be merged or consolidated shall be the successor to the Master Servicer under
the Sale and Master Servicing Agreement without the execution or filing of any
paper or any further act.
 
     The Sale and Master Servicing Agreement provides that neither the Master
Servicer nor any of its directors, officers, employees or agents shall have any
liability to the Issuer or to the Security Owners for any action taken, or for
refraining from taking any action, in good faith pursuant to the Sale and Master
Servicing Agreement or for errors in judgment, unless liability would otherwise
be imposed by reason of willful misfeasance, bad faith, negligence or reckless
disregard in performing the Master Servicer's duties or failure to perform its
duties.
 
MASTER SERVICER EVENTS OF DEFAULT
 
     "Master Servicer Events of Default" will consist of, among other things:
(i) (1) any failure of the Servicer to deposit in the Collection Account any
amount required to be deposited under the Servicing Agreement or the Sale and
Master Servicing Agreement, which failure continues unremedied for two Business
Days, (2) any failure of the Servicer to pay when due any amount required under
the Servicing Agreement or the Sale and Master Servicing Agreement and such
failure results in a draw under the Guaranty Policy and (3) the occurrence and
continuance of a Servicer Event of Default that continues unremedied for 30 days
after certain notices have been given; (ii) any failure by the Master Servicer
duly to observe or perform in any material respect any other of its covenants or
agreements in the Sale and Master Servicing Agreement or Servicing Agreement,
which failure continues unremedied for 30 days after notice; (iii) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceedings relating to the Master Servicer and certain
actions by the Master Servicer indicating insolvency, reorganization or
inability to pay its obligations (an "Insolvency Event") or the Master Servicer
shall dissolve or liquidate, in whole or in part, in any material respect; or
(iv) events established by the Securities Insurer, such as (1) the occurrence of
certain events which have a material adverse effect on the Master Servicer's
business, financial condition, operations or prospects; (2) a default by the
Master Servicer or any of its affiliates on a material obligation; (3) the
Master Servicer is no longer able to discharge its duties under the Sale and
Master Servicing Agreement; (4) the Master Servicer has ceased to conduct its
business in the ordinary course; and (5) certain other events of default
established by the Securities Insurer as further described in the Sale and
Master Servicing Agreement. Certain events of default may be eliminated with the
consent of the Securities Insurer.
 
                                      S-62
<PAGE>
     If a Master Servicer Event of Default shall occur and be continuing, the
Securities Insurer, or the Indenture Trustee with the prior written consent of
the Securities Insurer, or the holders of Notes representing more than 50% of
the aggregate voting interests of the Note with prior written consent of the
Securities Insurer, by notice given in writing to the Master Servicer (and to
the Indenture Trustee, if given by such holders of Notes) may terminate all of
the rights and obligations of the Master Servicer under the Sale and Master
Servicing Agreement, in which event another entity acceptable to the Securities
Insurer will become the successor Master Servicer. Upon the termination of the
Master Servicer, the Indenture Trustee is obligated to fulfill the duties of
master servicer until a successor is appointed. On or after the receipt by the
Master Servicer of such written notice, and the appointment of and acceptance of
appointment by a successor Master Servicer, all authority, power, obligations
and responsibilities of the Master Servicer under the Sale and Master Servicing
Agreement shall become obligations and responsibilities of the successor Master
Servicer.
 
     Upon the termination of the Master Servicer, the Master Servicer shall at
its own expense execute and deliver the documents reasonably requested in order
to orderly transfer the master servicing of the Loans. Any successor Master
Servicer shall be entitled to such compensation as the Master Servicer would
have been entitled to under the Sale and Master Servicing Agreement if the
Master Servicer had not resigned or been terminated thereunder.
 
CERTAIN MATTERS REGARDING THE SERVICER
 
     The Servicing Agreement provides that the Servicer shall not resign from
its obligations and duties thereunder except upon the determination that its
duties thereunder are no longer permissible under applicable law and that such
incapacity cannot be cured by the Servicer. Any determination permitting the
resignation of Servicer under the Servicing Agreement shall be evidenced by an
opinion of counsel, at the Servicer's expense, to the effect delivered to the
Master Servicer and the Securities Insurer in form and substance reasonably
acceptable to the Master Servicer and the Securities Insurer. The Servicer's
resignation shall not become effective until the Master Servicer or another
successor acceptable to the Securities Insurer has assumed the Servicer's
responsibilities and obligations under the Servicing Agreement.
 
     The Servicer has agreed not to merge or consolidate with any other company
or permit any other company to become the successor to the Servicer's business
unless, after the merger or consolidation, the successor or surviving entity
shall meet the qualifications of the Servicer set forth in the Servicing
Agreement, shall be approved in advance by the Master Servicer and the
Securities Insurer in their sole discretion, and shall expressly assume the
obligations of the Servicer under the Servicing Agreement.
 
SERVICER DETERMINATIONS AND EVENTS OF DEFAULT
 
     Under the Sale and Master Servicing Agreement and the Servicing Agreement,
the term of the Servicer shall be extendable for successive 90 day terms until
the Notes are paid in full, provided that prior to the expiration of each term
the Securities Insurer delivers written notice of renewal to the Servicer (each
such notice a "Servicer Extension Notice"). If a Servicer Extension Notice is
not delivered on or before the last day of the servicing term, the Servicer's
term will be terminated.
 
     "Servicer Event of Default" will consist of, among other things: (i) a
failure by the Servicer to make any deposit or payment, or to remit any payment,
required to be made under the terms of the Servicing Agreement and the Sale and
Master Servicing Agreement which continues unremedied for a period of two
Business Days; (ii) any failure on the part of the Servicer to remit certain
reports and certificates required under the terms of the Servicing Agreement,
and such failure continues for two Business Days after the date on which either
the Securities Insurer or the Master Servicer shall have given the Servicer
written notice of such failure and demanding that such failure be cured;
(iii) any failure on the part of the Servicer duly to observe or perform in any
material respect certain covenants and agreements in the Servicing Agreement, or
any breach of certain representations or warranties, which continues uncured for
a period of 10 days after the date on which either the Securities Insurer or the
Master Servicer shall have given to the Servicer written notice of such failure
or breach and demanding that such default be cured; (iv) any involuntary
petition in bankruptcy or any other similar petition shall be filed against the
Servicer seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution, or similar relief under any present or future federal,
state or other statute, law, or regulation, and shall remain in force
undischarged or unstayed for 45 days, or if any custodian, trustee, receiver
 
                                      S-63
<PAGE>
or liquidator of all or any substantial part of the assets of the Servicer shall
be appointed or take possession of such assets without the consent or
acquiescence of the Servicer and such appointment remains unvacated for
45 days; (v) the Servicer shall consent to the appointment of a trustee,
conservator, or receiver or liquidator in any insolvency, readjustment of debt,
marshaling of assets and liabilities, or similar proceedings of, or relating to,
the Servicer, or all or substantially all of the Servicer's property; (vi) the
Servicer shall admit in writing its inability to pay its debts generally as they
become due, file a petition to take advantage of any applicable insolvency or
reorganization statute, make an assignment for the benefit of its creditors, or
voluntarily suspend payment of its obligations or take any corporate action in
furtherance of the foregoing; (vii) the Servicer assigns or attempts to assign
its rights to the Servicing Compensation hereunder or attempts to assign the
Servicing Agreement or the servicing responsibilities thereunder or in the Sale
and Master Servicing Agreement without the consent of the Master Servicer and
the Securities Insurer except as otherwise expressly permitted by the terms of
the Servicing Agreement; or (viii) the Servicer fails to remain qualified as a
mortgage servicer for FHLMC loans and/or the Servicer disposes of substantially
all of its assets.
 
     In case of any Servicer Event of Default, the Securities Insurer (or in
certain instances, the Master Servicer) may provide the Servicer with written
notice of the termination of all of the Servicer's authority, powers, and rights
under the Servicing Agreement. On or after the receipt by the Servicer of such
written notice, all authority and power of the Servicer under the Servicing
Agreement and the Sale and Master Servicing Agreement shall terminate. The
Servicing Agreement provides that in such case either of the Securities Insurer
or the Master Servicer may execute and deliver on behalf of the Servicer, as the
Servicer's attorney-in-fact, all documents, and to do or accomplish all acts
that in the Securities Insurer's judgment may be necessary or appropriate to
effect termination (with or without cause). The Master Servicer is obligated to
perform the duties of servicer under the Servicing Agreement upon the
termination of the Servicer until a successor is appointed. The Servicer will
continue to provide services in accordance with the Servicing Agreement and the
Sale and Master Servicing Agreement until terminated, and shall in good faith
cooperate fully to transfer the servicing and the management of the Loans. The
Servicing Agreement requires that the Servicer cooperate with the Master
Servicer to effect the termination of its responsibilities, rights, and powers
thereunder, including providing to the Master Servicer all documents and records
reasonably requested to enable the Master Servicer or its designee to assume and
carry out the duties and obligations of the Servicer.
 
RIGHTS OF NOTEHOLDERS UPON OCCURRENCE OF EVENT OF DEFAULT
 
     Under the Indenture, a failure to pay the full amount of the portion of the
Noteholders' Interest Payment Amount payable to the Notes within five days of
the Payment Date on which such payment is due or the full amount of principal
thereon on the related Maturity Date (without regard to the amount of the
Available Collection Amount) will constitute an Event of Default (an "Event of
Default"), as will certain material breaches under the Insurance Agreement. See
also "Description of the Securities--Events of Default--Indenture" in the
accompanying prospectus for a description of certain other Events of Default.
 
     Upon the occurrence of an Event of Default, the Securities Insurer or
holders of Notes representing more than 50% of the aggregate of the voting
interests of the Notes then outstanding, with the prior written consent of the
Securities Insurer, may exercise their remedies under the Indenture.
 
RESTRICTIONS ON NOTEHOLDERS' RIGHTS
 
     So long as (i) there does not exist a continuing failure by the Securities
Insurer to make a required payment under the Guaranty Policy and (ii) certain
bankruptcy-related events specified in the Sale and Master Servicing Agreement
have not occurred with respect to the Securities Insurer (any of the events
described in (i) and (ii), a "Securities Insurer Default"), the Securities
Insurer will have the right to exercise all rights, including voting rights,
which the Security Owners are entitled to exercise pursuant to the Indenture and
Owner Trust Agreement ("Security Owner Rights"), without any consent of such
Security Owners; provided however, that without the consent of each holder of
the Notes affected thereby, the Securities Insurer shall not exercise such
Security Owner Rights to amend the indenture in any manner that would
(i) reduce the amount of, or delay the timing of, collections of payments on the
Loans or distributions which are required to be made on any Note, (ii) adversely
affect in any material respect the interests of the holders of the Notes or
(iii) alter the rights of any Security Owner to consent to any such amendment.

<PAGE>
THE OWNER TRUSTEE AND INDENTURE TRUSTEE
 
     The Owner Trustee and the Indenture Trustee (together, the "Trustees") and
any of their respective affiliates may hold Notes in their own names or as
pledgees.
 
     For the purpose of meeting the legal requirements of certain jurisdictions,
the Servicer, the Owner Trustee and the Indenture Trustee acting jointly (or in
some instances, the Owner Trustee or the Indenture Trustee acting alone) will
have the power to appoint co-trustees or separate trustees of all or any part of
the Issuer. In the event of such an appointment, all rights, powers, duties and
obligations conferred or imposed upon the Owner Trustee by the Sale and Master
Servicing Agreement and the Owner Trust Agreement and upon the Indenture Trustee
by the Sale and Servicing Agreement and the Indenture will be conferred or
imposed jointly upon the Owner Trustee and the Indenture Trustee, respectively,
and in each such case such separate trustee or co-trustee, or, in any
jurisdiction in which the Owner Trustee or Indenture Trustee will be incompetent
or unqualified to perform certain acts, singly upon such separate trustee or
co-trustee which will exercise and perform such rights, powers, duties and
obligations solely at the direction of the Owner Trustee or the Indenture
Trustee, respectively.
 
     The Owner Trustee may resign at any time, in which event the Administrator
will be obligated to appoint a successor thereto acceptable to the Securities
Insurer. The Administrator may remove the Owner Trustee if it ceases to be
eligible to continue as such under the Owner Trust Agreement, or becomes legally
unable to act or becomes insolvent. In such circumstances, the Administrator
will be obligated to appoint a successor Owner Trustee acceptable to the
Securities Insurer. Any resignation or removal of the Owner Trustee and
appointment of a successor thereto will not become effective until acceptance of
the appointment by such successor.
 
     The Indenture Trustee may resign at any time, in which event the Master
Servicer will be obligated to appoint a successor thereto acceptable to the
Securities Insurer. The holders of a majority in outstanding amount of the Notes
with the prior written consent of the Securities Insurer, may remove the
Indenture Trustee and may appoint a successor thereto acceptable to the
Securities Insurer. The Master Servicer, with the prior written consent of the
Securities Insurer, will be obligated to remove the Indenture Trustee if the
Indenture Trustee ceases to be eligible to continue as such under the Indenture
or becomes legally unable to act or becomes insolvent. In such circumstances,
the Master Servicer will be obligated to appoint a successor acceptable to the
Securities Insurer. Any such resignation or removal and appointment of a
successor will not become effective until acceptance of the appointment by such
successor and approval by the Securities Insurer.
 
     The Owner Trust Agreement and Indenture will provide that the applicable
Trustee will be entitled to indemnification by the Transferor, and will be held
harmless against, any loss, liability or expense incurred by them not resulting
from its own willful misfeasance, bad faith or negligence (other than by reason
of a breach of any of its representations or warranties to be set forth in the
Owner Trust Agreement or Indenture, as the case may be).
 
DUTIES OF THE OWNER TRUSTEE AND INDENTURE TRUSTEE
 
     The Owner Trustee will make no representations as to the validity or
sufficiency of the Owner Trust Agreement, the Securities (other than the
execution and authentication thereof) or of any Loans or related documents, and
will not be accountable for the use or application by the Depositor or the
Servicer of any funds paid to the Depositor or the Servicer in respect of the
Notes or the Loans, or the investment of any monies by the Servicer before such
monies are deposited into the Accounts. So long as no Event of Default will have
occurred and be continuing, the Owner Trustee will be required to perform only
those duties specifically required of it under the Owner Trust Agreement.
Generally, those duties will be limited to the receipt of the various
certificates, reports or other instruments required to be furnished to the Owner
Trustee under the Owner Trust Agreement, in which case they will only be
required to examine such certificates, reports or other instruments to determine
whether they conform to the requirements of the Owner Trust Agreement. The Owner
Trustee will not be charged with knowledge of a failure by the Servicer to
perform its duties under the Owner Trust Agreement or the Sale and Master
Servicing Agreement which failure constitutes a Servicer Event of Default,
unless the Owner Trustee obtains such actual knowledge of such failure as
specified in the Owner Trust Agreement.
 
     The Owner Trustee will be under no obligation to exercise any of the rights
or powers vested in it by the Owner Trust Agreement or to make any investigation
of matters arising thereunder or to institute, conduct or defend any litigation
thereunder or in relation thereto at the request, order or direction of any of
the holders of
 
                                      S-65
<PAGE>
Residual Interest Certificates, unless such holders have offered to the Owner
Trustee reasonable security or indemnity against the costs, expenses and
liabilities that may be incurred therein or thereby. Subject to the rights or
consent of the holders of Notes, the Securities Insurer and the Indenture
Trustee, no holder of a Residual Interest Certificate will have any right under
the Owner Trust Agreement to institute any proceeding with respect to the Owner
Trust Agreement, unless such holder previously has given to the Owner Trustee
written notice of the occurrence of a Servicer Event of Default and the Servicer
Event of Default arises from the Servicer's failure to remit payments when due.
 
     The Indenture Trustee will make no representations as to the validity or
sufficiency of the Indenture, the Notes (other than the authentication thereof)
or of any Loans or related documents, and will not be accountable for the use or
application by the Depositor or the Servicer of any funds paid to the Depositor
or the Servicer in respect of the Notes or the Loans, or the investment of any
monies by the Servicer before such monies are deposited into the Accounts. So
long as no Event of Default under the Indenture will have occurred and be
continuing, the Indenture Trustee will be required to perform only those duties
specifically required of it under the Indenture. Generally, those duties will be
limited to the receipt of the various certificates, reports or other instruments
required to be furnished to the Indenture Trustee under the Indenture, in which
case it will only be required to examine them to determine whether they conform
to the requirements of the Indenture and to the making of monthly distributions
to the Security Owners and the filing of claims under the Guaranty Policy. The
Indenture Trustee will not be charged with knowledge of a failure by the
Servicer or the Master Servicer to perform its duties under the Transfer and
Sale Agreements which failure constitutes an Event of Default under the
Indenture, unless the Indenture Trustee obtains such actual knowledge of such
failure as specified in the Indenture.
 
     The Indenture Trustee will be under no obligation to exercise any of the
rights or powers vested in it by the Indenture or to make any investigation of
matters arising thereunder or to institute, conduct or defend any litigation
thereunder or in relation thereto at the request, order or direction of any of
the holders of Notes, unless such holders have offered to the Indenture Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby. No holder of Notes will have any right
under the Indenture to institute any proceeding with respect to the Indenture,
unless such holder has obtained the prior written consent of the Securities
Insurer and such holder will previously have given to the Indenture Trustee
written notice of the occurrence of an Event of Default and (i) the Event of
Default arises from the Servicer's failure to remit payments when due or (ii)
holders of Notes representing more than 25% of the aggregate voting interests of
the Notes then outstanding have made written request upon the Indenture Trustee
to institute such proceeding in its own name as the Indenture Trustee thereunder
and have offered to the Indenture Trustee reasonable indemnity and the Indenture
Trustee has for 30 days neglected or refused to institute any such proceedings.
 
REPORTS TO NOTEHOLDERS
 
     On each Payment Date, the Indenture Trustee is required to distribute,
based on information provided by the Servicer, a monthly statement (the
"Distribution Statement") to the Depositor, the holders of Notes, the Securities
Insurer, and the Rating Agencies, stating the date of original issuance of the
Notes and such other information, including the following:
 
          (1) the Available Collection Amount and Available Payment Amount, the
     Regular Payment Amount, the Insured Payment and the Excess Spread for the
     related Payment Date;

     after giving effect to payments made to the holders of such Notes on such
     Payment Date, and the Pool Principal Balance as of the first and last day
     of the related Due Period;
 
          (3) the Note Factor with respect to the Notes then outstanding ("Note
     Factor") means with respect to the Notes and any date of determination, the
     then applicable Note Principal Balance divided by the Original Note
     Principal Balance thereof;
 
          (4) the amount of principal, if any, and interest to be paid to the
     Notes on the related Payment Date;
 
          (5) as of such Payment Date, the Overcollateralization Amount, the
     Overcollateralization Target Amount and any Overcollateralization
     Deficiency Amount, or any Overcollateralization Reduction Amount,
 
                                      S-66

     and any such amount to be paid to the holders of the Notes or paid to the
     holders of the Residual Interest Certificates on such Payment Date;

     the Indenture Trustee Fee, if any, for such Payment Date and the Guaranty
     Insurance Premium;

     Overcollateralization Target Amount as of such Payment Date;
 
          (8) the weighted average maturity of the Loans and the weighted
     average Loan Rate of the Loans;
 
          (9) certain performance information with respect to the related Due

          (10) the number of and aggregate Principal Balance of all Loans in
     foreclosure proceedings and the percent of the aggregate Principal Balances
     of such Loans to the aggregate Principal Balances of all Loans, all as of
     the close of business on the last day of the related Due Period;
 
          (11) the number of and the aggregate Principal Balance of the Loans in
     bankruptcy proceedings and the percent of the aggregate Principal Balances
     of such Loans to the aggregate Principal Balances of all Loans, all as of
     the close of business on the last day of the related Due Period;
 
          (12) the number of foreclosure properties, the aggregate Principal
     Balance of the related Loans, the book value of such foreclosure properties
     and the percent of the aggregate Principal Balances of such Loans to the
     aggregate Principal Balances of all Loans, all as of the close of business
     on the last day of the related Due Period;
 
          (13) during the related Due Period (and cumulatively, from the Closing
     Date through the most current Due Period), the number and aggregate
     Principal Balance of Loans for each of the following: (a) that became

     related Due Period.
 
                        FEDERAL INCOME TAX CONSEQUENCES
 
     Set forth below is a summary of certain United States federal income tax
considerations relevant to the beneficial owner of a Note that holds the Note as
a capital asset and, unless otherwise indicated below, is a United States person
(as defined in the accompanying prospectus). This summary does not address
special tax rules that may apply to certain types of investors (such as banks,
insurance companies and securities dealers), and investors that hold Notes as
part of an integrated investment. This summary supplements the discussion
contained in the accompanying prospectus under the heading "Certain Federal
Income Tax Consequences," and supersedes that discussion to the extent that it
is inconsistent therewith. The authorities on which this discussion is based are
subject to change or differing interpretations, and any such change or
interpretation could apply retroactively. This discussion reflects the
applicable provisions of the Code, as well as regulations promulgated by the
U.S. Department of the Treasury. Investors should consult their own tax advisors
in determining the federal, state, local and any other tax consequences to them
of the purchase, ownership and disposition of the Notes.
 
CLASSIFICATION OF INVESTMENT ARRANGEMENT
 
     In the opinion of Cadwalader, Wickersham & Taft, special counsel to the
Depositor, the Issuer will not be treated as an association or a publicly traded
partnership taxable as a corporation or a taxable mortgage pool for federal
income tax purposes, but rather the Issuer will be ignored and treated as a mere
security device when there is a single beneficial owner of the Issuer, or will
be treated as a domestic partnership when there are two or more beneficial
owners of the Issuer.
 
                                      S-67
<PAGE>
TAXATION OF HOLDERS
 
     Characterization of the Notes. There are no regulations, published rulings
or judicial decisions addressing the characterization for federal income tax
purposes of securities with terms that are substantially the same as those of
the Notes. A basic premise of United States federal income tax law is that the
economic substance of a transaction generally will determine the United States
federal income tax consequences of such transaction. The determination of
whether the economic substance of a loan secured by an interest in property is
instead a sale of a beneficial ownership interest in such property has been made
by the Internal Revenue Service and the courts on the basis of numerous factors
designed to determine whether the issuer has relinquished (and the investor has
obtained) substantial incidents of ownership in such property. Among those
factors, the primary factors examined are whether the investor has the
opportunity to gain if the property increases in value, and has the risk of loss
if the property decreases in value. Based on an assessment of these factors, in
the opinion of Cadwalader, Wickersham & Taft, special counsel to the Depositor,
the Notes will be treated as indebtedness for federal income tax purposes and
not as an ownership interest in the Loans or an equity interest in the Issuer.
 
     Interest and Original Issue Discount. Interest on the Notes will be treated
as income to beneficial owners as such amounts are paid or accrue in accordance
with the holder's method of accounting. It is anticipated that the Notes will
not be issued with original issue discount for federal income tax purposes. Any
premium or de minimis original issue discount with respect to the Notes will be
determined in the same manner as described under "Certain Federal Income Tax
Consequences--REMICs--Taxation of Owners of Regular Securities--Premium" and
"--Original Issue Discount" in the accompanying prospectus. The prepayment
assumption that will be used for accruing original issue discount, for
determining if original issue discount is de minimis or for amortizing premium
for federal income tax purposes is 30% CPR.
 
     Sale, Exchange, Retirement or Other Disposition. Upon the sale, exchange,
retirement or other disposition of a Note, a beneficial owner who holds the Note
as a capital asset generally will recognize capital gain or loss equal to the
difference, if any, between the amount realized (adjusted for accrued stated
interest) on the sale or other disposition of the owner's Note and the owner's
cost for such Note, increased by any original issue discount or accrued market
discount reported as income or decreased by any amortized bond premium.
Long-term capital gains of non-corporate investors (generally, gains on notes
held for more than one year) would be subject to a lower maximum tax rate than
ordinary income or short-term capital gains of such holders. Corporations are
subject to the same tax rate on ordinary income and capital gains.
 
     Taxation of Certain Foreign Investors. Interest, including original issue
discount, payable to beneficial owners of Notes who are nonresident aliens,
foreign corporations, or other Non-U.S. Persons (i.e., any person who is not a
"U.S. Person," as defined below), will be considered "portfolio interest" and,
therefore, generally will not be subject to 30% United States withholding tax,
provided that such Non-U.S. Person (i) is not a "10-percent shareholder" within
the meaning of Code Section 871(h)(3)(B) or a controlled foreign corporation
described in Code Section 881(c)(3)(C) with respect to the Depositor or the
Issuer and (ii) provides the Owner Trustee, or the person who would otherwise be
required to withhold tax from such distributions under Code Section 1441 or
1442, with an appropriate statement, signed under penalties of perjury,
identifying the beneficial owner and stating, among other things, that the
beneficial owner of the Note is a Non-U.S. Person. If such statement, or any
other required statement, is not provided, 30% withholding will apply unless
reduced or eliminated pursuant to an applicable tax treaty or unless the
interest on the Note is effectively connected with the conduct of a trade or
business within the United States by such Non-U.S. Person. In the latter case,
such Non-U.S. Person will be subject to United States federal income tax at
regular rates. Investors who are Non-U.S. Persons should consult their own tax
advisors regarding the specific tax consequences to them of owning an Offered
Certificate. The term "U.S. Person" means a citizen or resident of the United
States, a corporation or partnership (except to the extent provided in
applicable Treasury regulations) created or organized in or under the laws of
the United States, any state or the District of Columbia, including any entity
treated as a corporation or partnership for federal income tax purposes, an
estate that is subject to U.S. federal income tax regardless of the source of
its income, or a trust if a court within the United States is able to exercise
primary supervision over the administration of the trust and one or more such
U.S. Persons have the authority to control all substantial decisions of the
trust (or, to the extent provided in applicable Treasury regulations, certain
trusts in existence on August 20, 1996 which are eligible to elect to be treated
as U.S. Persons).

     The IRS recently issued final regulations (the "New Regulations") which
would provide alternative methods of satisfying the beneficial ownership
certification requirement described above. The New Regulations are effective
January 1, 2000, although valid withholding certificates that are held on
December 31, 1999, remain valid until the earlier of December 31, 2000 or the
due date of expiration of the certificate under the rules as currently in
effect. The New Regulations would require, in the case of Notes held by a
foreign partnership, that (x) the certification described above be provided by
the partners rather than by the foreign partnership and (y) the partnership
provide certain information, including a United States taxpayer identification
number. A look-through rule would apply in the case of tiered partnerships.
Non-U.S. Persons should consult their own tax advisors concerning the
application of the certification requirements in the New Regulations.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     Payments made on the Notes and proceeds from the sale of Notes to or
through certain brokers may be subject to a "backup" withholding tax of 31% of
"reportable payments" (including interest accruals, original issue discount,
and, under certain circumstances, payments in respect of principal amount)
unless, in general, the beneficial owner complies with certain procedures or is
an exempt recipient. Any amounts so withheld from payments on the Notes would be
refunded by the Internal Revenue Service or allowed as a credit against the
beneficial owner's federal income tax. The New Regulations change certain of the
rules relating to certain presumptions currently available relating to
information reporting and backup withholding. Non-U.S. Persons are urged to
contact their own tax advisors regarding the application to them of backup
withholding and information reporting.
 
     Reports of interest, original issue discount and certain information needed
to compute accrued market discount will be made annually to the Internal Revenue
Service and to beneficial owners that are not excepted from the reporting
requirements.

Funds--Treatment of the Debt Securities as Indebtedness" in the accompanying

                              ERISA CONSIDERATIONS
 
GENERAL
 
     Title I of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and section 4975 of the Internal Revenue Code of 1986, as amended
(the "Code"), impose certain restrictions on retirement plans and other employee
benefits plans or arrangements subject thereto ("Plans") and on persons who are
parties in interest or disqualified persons ("Parties in Interest") with respect
to such Plans. Certain employee benefit plans, such as governmental plans and
church plans (if no election has been made under section 410(d) of the Code) are
not subject to the restrictions of ERISA, and assets of such plans may be
invested in the Notes without regard to the ERISA considerations described
below, subject to other applicable federal and state law. However, any such
governmental or church plan which is qualified under section 401(a) of the Code
and exempt from taxation under section 501(a) of the Code is subject to the
prohibited transaction rules set forth in section 503 of the Code. Any Plan
fiduciary which proposes to cause a Plan to acquire any of the Notes should
consult with its counsel with respect to the potential consequences under ERISA
and the Code of the Plan's acquisition and ownership of the Notes. See "ERISA
Considerations" in the accompanying prospectus. Investments by Plans are also
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.
 
PROHIBITED TRANSACTIONS
 
     General.  Section 406 of ERISA prohibits Parties in Interest with respect
to a Plan from engaging in certain transactions (including loans) involving a
Plan and its assets unless a statutory or administrative exemption applies to
the transaction. Section 4975 of the Code imposes certain excise taxes (or, in
some cases, a civil penalty may be assessed pursuant to section 502(i) of ERISA)
on Parties in Interest which engage in non-exempt prohibited transactions.
 
     Plan Asset Regulation.  The United States Department of Labor (the "DOL")
has issued regulations concerning the definition of what constitutes the assets
of a Plan for purposes of ERISA and the prohibited transaction provisions of the
Code (the "Plan Asset Regulation"). The Plan Asset Regulation describes the
circumstances under which the assets of an entity in which a Plan invests will
be considered to be "plan assets" such that any person who exercises control
over such assets would be subject to ERISA's fiduciary standards. Under the Plan
Asset Regulation, generally when a Plan invests in another entity, the Plan's
assets do not include, solely by reason of such investment, any of the
underlying assets of the entity. However, the Plan Asset Regulation provides
that, if a Plan acquires an "equity interest" in an entity, the assets of the
entity will be treated as assets of the Plan investor unless certain exceptions
not applicable here apply.
 
     Under the Plan Asset Regulation, the term "equity interest" is defined as
any interest in an entity other than an instrument that is treated as
indebtedness under "applicable local law" and which has no "substantial equity
features." If the Notes are not treated as equity interests in the Issuer for
purposes of the Plan Asset Regulation, a Plan's investment in such Notes would
not cause the assets of the Issuer to be deemed Plan assets. However, the
Depositor, the Servicer, the Indenture Trustee, and the Owner Trustee may be the
sponsor of or investment advisor with respect to one or more Plans. Because such
parties may receive certain benefits in connection with the sale of Notes, the
purchase of Notes using Plan assets over which any such parties has investment
authority might be deemed to be a violation of the prohibited transaction rules
of ERISA and the Code for which no exemption may be available. Accordingly,
Notes may not be purchased using the assets of any Plan if the Depositor, the
Servicer, the Indenture Trustee, or the Owner Trustee has investment authority
with respect to such assets.
 
     In addition, certain affiliates of the Issuer might be considered or might
become Parties in Interest with respect to a Plan. Also, any holder of Residual
Interest Certificates, because of its activities or the activities of its
respective affiliates, may be deemed to be a Party in Interest with respect to
certain Plans, including but not limited to Plans sponsored by such holder. In
either case, the acquisition or holding of Notes by or on behalf of such a Plan
could be considered to give rise to an indirect prohibited transaction within
the meaning of ERISA and the Code, unless it is subject to one or more
exemptions such as Prohibited Transaction Class Exemption ("PTCE") 84-14, which
exempts certain transactions effected on behalf of a Plan by a "qualified
professional
 
                                      S-70
<PAGE>
asset manager," PTCE 90-1, which exempts certain transactions involving
insurance company pooled separate accounts, PTCE 91-38, which exempts certain
transactions involving bank collective investment funds, PTCE 95-60, which
exempts certain transactions involving insurance company general accounts, or
PTCE 96-23, which exempts certain transactions effected on behalf of a Plan by
certain "in-house asset managers." Each purchaser or transferee of a Note that
is a Plan or is investing assets of a Plan shall be deemed to have represented
that the relevant conditions for exemptive relief under at least one of the
foregoing exemptions have been satisfied.
 
     If the Notes are deemed to be equity interests in the Issuer, the Issuer
could be considered to hold Plan assets by reason of a Plan's investment in the
Notes. In such an event, the Servicer and other persons exercising management or
discretionary control over the assets of the Issuer may be deemed to be
fiduciaries with respect to investing Plans and thus subject to the fiduciary
responsibility provisions of Title I of ERISA, including the prohibited
transaction provisions of section 406 of ERISA, and section 4975 of the Code
with respect to transactions involving the Issuer's assets. There can be no
assurance that any statutory or administrative exemption will apply to all
prohibited transactions that might arise in connection with the purchase or
holding of an equity interest in the Issuer by a Plan.
 
REVIEW BY PLAN FIDUCIARIES
 
     Any Plan fiduciary considering whether to purchase any Notes on behalf of a
Plan should consult with its counsel regarding the applicability of the
fiduciary responsibility and prohibited transaction provisions of ERISA and the
Code to such investment and the availability of any prohibited transaction
exemptions. The sale of Notes to a Plan is in no respect a representation by the
Depositor or the Underwriter that this investment meets all relevant
requirements with respect to investments by Plans generally or any particular
Plan or that this investment is appropriate for Plans generally or any
particular Plan.
 
                            LEGAL INVESTMENT MATTERS
 
     The Notes will constitute "mortgage related securities" for purposes of the
Secondary Mortgage Market Enhancement Act of 1984, as amended ("SMMEA") for as
long as they are rated not lower than the second highest rating category by one
or more nationally recognized statistical rating organizations and, as such,
will be legal investments for certain entities to the extent provided in SMMEA
and applicable state laws.
 
     Except as noted above, no representation is made as to the proper
characterization of the Notes for legal investment purposes, financial
institution regulatory purposes, or other purposes, or as to the ability of
particular investors to purchase the Notes under applicable legal investment
restrictions. These uncertainties may adversely affect the liquidity of the
Notes. Accordingly, all institutions whose investment activities are subject to
legal investment laws and regulations, regulatory capital requirements or review
by regulatory authorities should consult with their own legal advisors in
determining whether and to what extent the Notes constitute a legal investment
or are subject to investment, capital or other restrictions. See "Legal
Investment" in the prospectus.
 
                                USE OF PROCEEDS
 
     The Depositor intends to use the net proceeds to be received from the sale
of the Notes to acquire the Loans and to pay other expenses associated with the
pooling of the Loans and the issuance of the Notes.
 
                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the Underwriting Agreement
between the Depositor and PaineWebber Incorporated, Credit Suisse First Boston
Corporation and Chase Securities Inc. (collectively, the "Underwriters"), the
Depositor has agreed to sell to the Underwriters, and the Underwriters have
agreed to purchase from the Depositor, the Notes. The Depositor has been advised
by the Underwriters that the Underwriters propose initially to offer the Notes
to the public at a price equal to 100.00% of the initial Note Principal Balance
and to certain dealers at such prices less a concession not in excess of 0.15%
(expressed as a percentage of the Note Principal Balance). The Underwriters may
allow and such dealers may allow a discount not in excess of 0.105%. The
Depositor estimates that its aggregate expenses in connection with the issuance
and
 
                                      S-71
<PAGE>
offering of the Notes, excluding underwriting discounts and commissions, will be
approximately $500,000. The Underwriters will receive an underwriting discount
equal to 0.25% of the initial principal amount of the Notes. In connection with
the sale of the Notes, the Underwriters will be deemed to have received
compensation from the Depositor in the form of underwriting discounts equal to
0.25% of the initial Note Principal Balance.
 
     Until the distribution of the Notes is completed, rules of the Commission
may limit the ability of the Underwriters and certain selling group members to
bid for and purchase the Notes. As an exception to these rules, the Underwriters
are permitted to engage in certain transactions that stabilize the price of the
Notes. Such transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the Notes.
 
     If the Underwriters create a short position in the Notes in connection with
the offering, i.e., if they sell more Notes than are set forth on the cover page
of this prospectus supplement, the Underwriters may reduce that short position
by purchasing Notes in the open market.
 
     In general, purchase of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases.
 
     Neither the Depositor nor the Underwriters make any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Notes. In addition, neither the
Depositor nor the Underwriters make any representation that the Underwriters
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.
 
     There is currently no secondary market for the Notes. There can be no
assurance that a secondary market for the Notes will develop or, if it does
develop, that it will continue.
 
     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.
 
     In addition to the purchase of the Notes pursuant to the Underwriting
Agreement, the Underwriters and certain of their affiliates may have certain
financing relationships with the Transferor.
 
     The Depositor is an affiliate of PaineWebber Incorporated. Any obligations
of PaineWebber Incorporated are the sole responsibility of PaineWebber
Incorporated and do not create any obligations on the part of any of its
affiliates.

     The consolidated balance sheets of Financial Security Assurance Inc. and
subsidiaries as of December 31, 1997 and December 31, 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 into 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.
 
                                 LEGAL MATTERS
 
     The validity of the Notes and certain federal income tax matters will be
passed upon for the Depositor and for the Underwriters by Cadwalader, Wickersham
& Taft, New York, New York. Certain matters will be passed upon for the
Transferor and Master Servicer by Hunton & Williams, Richmond, Virginia.
 
                                    RATINGS
 
     It is a condition to the issuance of the Notes that the Notes be rated
"Aaa" by Moody's Investors Service, Inc. and "AAA" by Standard & Poor's Ratings
Services, a division of The McGraw-Hill Companies, Inc. The ratings on the Notes
address the likelihood of the receipt by the holders of the Notes of all
payments on the Loans to which they are entitled. The ratings on the Notes also
address the structural, legal and issuer-related aspects of the Notes, including
the nature of the Loans. In general, the ratings on the Notes address credit
risk and not prepayment risk. The ratings on the Notes do not represent any
assessment of the likelihood that principal
 
                                      S-72
<PAGE>
prepayments of the Loans will be made by borrowers or the degree to which the
rate of such prepayments might differ from that originally anticipated. As a
result, the initial ratings assigned to the Notes do not address the possibility
that holders of the Notes might suffer a lower than anticipated yield in the
event of principal payments on the Notes resulting from rapid prepayments of the
Loans, the payment of any Noteholders' Interest Carry-Forward Amount, or the
application of Excess Spread as described in this prospectus supplement, or if
the Owner Trust is terminated before the final Maturity Date of the Notes.
 
     The Depositor has not solicited ratings on the Notes with any rating agency
other than the Rating Agencies. However, there can be no assurance as to whether
any other rating agency will rate the Notes or, if it does, what rating would be
assigned by any such other rating agency. Any rating on the Notes by another
rating agency, if assigned at all, may be lower than the ratings assigned to the
Notes by the Rating Agencies.
 
     A security rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
organization. Each security rating should be evaluated independently of any
other security rating. If the ratings initially assigned to any of the Notes by
the Rating Agencies are subsequently lowered for any reason, no person or entity
is obligated to provide any additional support or credit enhancement with
respect to such Notes.

                 PAINEWEBBER MORTGAGE ACCEPTANCE CORPORATION IV
                                   Depositor

                           ASSET-BACKED CERTIFICATES
                               ASSET-BACKED NOTES
                              (Issuable in Series)
 
     Principal and interest with respect to Securities will be payable monthly,
quarterly, semiannually or at such other intervals on the dates specified in the
related Prospectus Supplement.
 
     The mortgage pass-through certificates ("Certificates") or mortgaged-backed
notes ("Notes") offered hereby (together, "Securities") and by Supplements to
this Prospectus will be offered from time to time in one or more series (each, a
"Series"). Each Series of Securities will represent in the aggregate the entire
beneficial ownership interest in a Trust Fund consisting primarily of a
segregated pool of various types of single-family and multifamily residential
mortgage loans, home improvement contracts, cooperative apartment loans or
manufactured housing conditional sales contracts and installment loan agreements
(collectively, the "Residential Loans"), or beneficial interests therein (which
may include Mortgage Securities as defined herein), pass-through or
participation certificates issued or guaranteed by the Government National
Mortgage Association ("GNMA"), the Federal National Mortgage Association
("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC") (any such
certificates, "Agency Securities"). Information regarding a Series of Securities
and the composition of the related Trust Fund will be furnished at the time of
offering in a Prospectus Supplement.
 
     Each Series of Securities will include one or more classes. Each class of
Securities of any Series will represent the right, which right may be senior to
the rights of one or more of the other classes of the Certificates, to receive a
specified portion of payments of principal and interest on the Residential Loans
or Agency Securities in the related Trust Fund in the manner described herein
and in the related Prospectus Supplement. A Series may include one or more
classes of Securities entitled to principal distributions, with
disproportionate, nominal or no interest distributions, or to interest
distributions, with disproportionate, nominal or no principal distributions. See
"Description of the Certificates." A Series may include two or more classes of
Securities which differ as to the timing, sequential order or amount of
distributions of principal or interest or both. If so specified in the related
Prospectus Supplement, the Trust Fund for a Series of Securities may include
insurance policies, surety bonds, guarantees, letters of credit, reserve funds,
cash accounts, reinvestment income or other types of credit support, or any
combination thereof. See "Description of Credit Support."
 
     FOR A DISCUSSION OF CERTAIN RISKS ASSOCIATED WITH AN INVESTMENT IN THE
SECURITIES, SEE THE INFORMATION UNDER "RISK FACTORS" ON PAGE 13.
 
     The only obligations of the Depositor with respect to a Series of
Securities will be pursuant to its representations and warranties as described
herein. The Master Servicer with respect to a Series of Securities evidencing
interests in a Trust Fund including Residential Loans will be named in the
related Prospectus Supplement. The principal obligations of a Master Servicer
will be limited to its contractual servicing obligations, and, to the extent
described in the related Prospectus Supplement, its obligation to make certain
cash advances in the event of payment delinquencies on the Residential Loans.
 
     Each Trust Fund will be held in trust for the benefit of the holders of the
related Series of Securities as more fully described herein. With respect to
each Series of Certificates, if specified in the related Prospectus Supplement,
one or more elections may be made to treat the related Trust Fund as a "real
estate mortgage investment conduit" ("REMIC") for federal income tax purposes.
See "Certain Federal Income Tax Consequences."

     THE SECURITIES OF EACH SERIES WILL NOT REPRESENT AN INTEREST IN OR
OBLIGATION OF THE DEPOSITOR, THE MASTER SERVICER, THE TRUSTEE OR ANY OF THEIR
RESPECTIVE AFFILIATES, EXCEPT AS SET FORTH HEREIN AND IN THE RELATED PROSPECTUS
SUPPLEMENT. NEITHER THE SECURITIES NOR, EXCEPT AS SET FORTH HEREIN OR IN THE
RELATED PROSPECTUS SUPPLEMENT, ANY UNDERLYING RESIDENTIAL LOAN (OTHER THAN
RESIDENTIAL LOANS IDENTIFIED AS FHA LOANS OR VA LOANS IN THE RELATED PROSPECTUS
SUPPLEMENT) OR ANY MORTGAGE SECURITY, WILL BE INSURED OR GUARANTEED BY ANY
GOVERNMENTAL AGENCY OR INSTRUMENTALITY. ALTHOUGH PAYMENT OF PRINCIPAL AND
INTEREST ON AGENCY SECURITIES WILL BE GUARANTEED AS DESCRIBED HEREIN AND IN THE
RELATED PROSPECTUS SUPPLEMENT BY GNMA, FNMA OR FHLMC, THE CERTIFICATES OF ANY
SERIES EVIDENCING INTERESTS IN A TRUST FUND INCLUDING SUCH AGENCY SECURITIES
WILL NOT BE SO GUARANTEED.
 
     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.
 
     The Securities may be offered through one or more different methods,
including offerings through underwriters, as more fully described under "Plans
of Distribution" and in the related Prospectus Supplement. The Depositor may
retain or hold for sale, from time to time, one or more classes of a Series of
Securities.
 
     The Depositor does not intend to list any of the Securities on any
securities exchange and has not made any other arrangement for secondary trading
of the Securities. With respect to each Series, all of the Securities of each
class offered hereby will be rated in one of the four highest rating categories
by one or more nationally recognized statistical rating organizations. There
will have been no public market for any Series of Securities prior to the
offering thereof. No assurance can be given that such a market will develop as a
result of such an offering.
 
     The Securities are offered when, as and if delivered to and accepted by the
underwriters subject to prior sale, withdrawal or modification of the offer
without notice, the approval of counsel and other conditions. Retain this
Prospectus for future reference. This Prospectus may not be used to consummate
sales of the securities offered hereby unless accompanied by a Prospectus
Supplement.
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATIONS OTHER THAN THOSE CONTAINED IN THIS PROSPECTUS OR THE RELATED
PROSPECTUS SUPPLEMENT AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATIONS
MUST NOT BE RELIED UPON. THIS PROSPECTUS AND THE RELATED PROSPECTUS SUPPLEMENT
DO NOT CONSTITUTE AN OFFER TO SELL OR A SOLICITATION OF AN OFFER TO BUY ANY
SECURITIES OTHER THAN THE SECURITIES OFFERED HEREBY AND THEREBY NOR AN OFFER OF
THE SECURITIES TO ANY PERSON IN ANY STATE OR OTHER JURISDICTION IN WHICH SUCH
OFFER WOULD BE UNLAWFUL. THE DELIVERY OF THIS PROSPECTUS OR THE RELATED
PROSPECTUS SUPPLEMENT AT ANY TIME DOES NOT IMPLY THAT INFORMATION THEREIN IS
CORRECT AS OF ANY TIME SUBSEQUENT TO THEIR RESPECTIVE DATE.

                                            Series of Notes where the Issuer is an owner trust, the ownership of
                                            the Trust Fund will be evidenced by certificates (the "Equity
                                            Certificates") issued under the Owner Trust Agreement, which, unless
                                            otherwise specified in the Prospectus Supplement, are not offered
                                            hereby. The Notes will represent nonrecourse obligations solely of
                                            the Issuer, and the proceeds of the Trust Fund will be the sole
                                            source of payments on the Notes, except as described herein under

                                            Securities ("Accrual Securities"), as to which accrued interest will
                                            not be distributed but rather will be added to the Security Principal
                                            Balance thereof on each Distribution Date, as hereinafter defined, in
                                            the manner described in the related Prospectus Supplement.
 
                                            As to each Series relating only to Certificates, one or more

                                            If any such election is made as to any Series, one of the classes of
                                            Certificates comprising such Series will be designated as evidencing
                                            all "residual interests" in the related REMIC as defined in the Code.

                                            providing the coverage (if applicable), the terms of any
                                            subordination and related information with respect to each type of
                                            credit support, if any, will be set forth in the related Prospectus
                                            Supplement for a Series of Securities. If specified in the related
                                            Prospectus Supplement, the coverage provided by one or more forms of
                                            credit support 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 support relates and the manner
                                            of determining the amount of the coverage provided thereby and the
                                            application of such coverage to the identified Trust Funds. See
                                            "Description of Credit Support" and "Description of the
                                            Securities--Subordination."
 
Servicing and Advances....................  The Master Servicer, directly or through sub-servicers, will service
                                            and administer the Residential Loans included in a Trust Fund and,
                                            unless the related Prospectus Supplement provides otherwise, in
                                            connection therewith (and pursuant to the terms of the related
                                            Mortgage Securities, if applicable) will be obligated to make certain
                                            cash advances with respect to delinquent scheduled payments on the
                                            Residential Loans or will be obligated to make such cash advances
                                            only to the extent that the Master Servicer determines that such
                                            advances will be recoverable (any such advance, an "Advance").
                                            Advances made by the Master Servicer will be reimbursable to the
                                            extent described herein and in the related Prospectus Supplement. The
                                            Prospectus Supplement with respect to any Series may provide that the
                                            Master Servicer will obtain a cash advance surety bond, or maintain a
                                            cash advance reserve fund, to cover any obligation of the Master
                                            Servicer to make advances. The obligor on any such surety bond will
                                            be named, and the terms applicable to any such cash advance reserve
                                            fund will be described in the related Prospectus Supplement. See
                                            "Description of the Securities--Advances."
 
Optional Termination......................  If so specified in the related Prospectus Supplement, a Series of
                                            Securities may be subject to optional early termination ("Optional
                                            Termination") through the repurchase of the assets in the related
                                            Trust Fund by the party entitled to effect such termination, under
                                            the circumstances and in the manner set forth herein under
                                            "Description of the Securities--Termination" herein and in the
                                            related Prospectus Supplement.

                                            (i) interests ("Grantor Trust Certificates") in a Trust Fund treated
                                            as a grantor trust under applicable provisions of the Code, or (ii)
                                            "regular interests" ("REMIC Regular Certificates") or "residual

Legal Investment..........................  The Prospectus Supplement for each Series of Securities will specify
                                            which, if any, of the Securities offered thereby constitute at the
                                            date of issuance "mortgage related securities" for purposes of the
                                            Secondary Mortgage Market Enhancement Act of 1984, as amended
                                            ("SMMEA"). 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 and to
                                            what extent a class of Securities constitutes a legal investment for
                                            them. See "Legal Investment."
 
Use of Proceeds...........................  The Depositor will use the net proceeds from the sale of each Series
                                            for one or more of the following purposes: (i) to purchase the
                                            related Trust Fund Assets, (ii) to repay indebtedness which has been
                                            incurred to obtain funds to acquire such Trust Fund Assets, (iii) to
                                            establish any Reserve Funds described in the related Prospectus
                                            Supplement and (iv) to pay costs of structuring, guaranteeing and
                                            issuing such Securities. If so specified in the related Prospectus
                                            Supplement, the purchase of the Trust Fund Assets for a Series may be
                                            effected by an exchange of Securities with the Depositor of such
                                            Trust Fund Assets. See "Use of Proceeds."
 
Ratings...................................  Unless otherwise specified in the related Prospectus Supplement, it
                                            will be a requirement for issuance of any Series that the Securities
                                            offered by this Prospectus and such Prospectus Supplement be rated by
                                            at least one Rating Agency in one of its four highest applicable
                                            rating categories. The rating or ratings applicable to Securities of
                                            each Series offered hereby and by the related Prospectus Supplement
                                            will be as set forth in the related Prospectus Supplement. A
                                            securities rating should be evaluated independently of similar
                                            ratings on different types of securities. A security rating does not
                                            address the effect that the rate of prepayments on Residential Loans
                                            comprising or underlying the Trust Fund Assets may have on the yield
                                            to investors in the Securities. See "Risk Factors."

                                  RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with the purchase of the Securities offered hereby and by the related
Prospectus Supplement.
 
LIMITED LIQUIDITY
 
     There can be no assurance that a secondary market for the Securities of any
Series will develop or, if it does develop, that it will provide holders with
liquidity of investment or will continue while Securities of such Series remain
outstanding. The market value of Securities of each Series will fluctuate with
changes in prevailing rates of interest. Consequently, sale of the Securities by
a holder in any secondary market that may develop may be at a discount from par
value or from its purchase price. Holders of Securities have no optional
redemption rights. Unless otherwise provided in the related Prospectus
Supplement, PaineWebber expects to make a secondary market in the Securities
offered hereby, but is not obligated to do so.
 
LIMITED ASSETS
 
     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.
Furthermore, at the times set forth in the related Prospectus Supplement,
certain Trust Fund Assets and/or any balance remaining in the Trust 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 or any of their respective affiliates. The only
obligations, if any, of the Depositor with respect to the Trust Fund Assets and
the other assets constituting the Trust Fund for a Series of Securities, 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
Trust Fund Assets with respect to which there has been a breach of any
representation or warranty. If, for example, the Depositor were required to
repurchase a Residential 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 seller or originator of such Residential
Loan, or (ii) from a reserve account or similar credit enhancement established
to provide funds for such repurchases. The Master Servicer's servicing
obligations under the related Agreement may include its limited obligation to
make certain advances in the event of delinquencies on the Residential Loans,
but only to the extent deemed recoverable. To the extent described in the
related Prospectus Supplement, the Depositor, Master Servicer or Trustee will be
obligated under certain limited circumstances to purchase or act as a
remarketing agent with respect to a convertible Residential Loan upon the
conversion of the interest rate thereon to a fixed rate.
 
CREDIT ENHANCEMENT
 
     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 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 may suffer losses. Moreover, such credit
enhancement may not cover all potential losses or risks. For example, credit
enhancement may or may not cover, or may cover only in part, fraud or negligence
by a loan originator or other parties. See "Description of Credit Support."
 
                                       13
<PAGE>
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 of the Residential Loans and, in the case of Agency Securities, the
underlying loans related thereto, comprising the Trust Fund, which prepayments
may be influenced by a variety of factors, (ii) the manner of allocating
principal and/or payment 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. Prepayments of principal may also result from repurchases of Trust Fund
Assets due to material breaches of the Unaffiliated Seller's (as defined
herein), originator's, Depositor's or Master Servicer's representations and
warranties, as applicable. The yield to maturity experienced by a holder of
Securities may be affected by the rate of prepayment of the Residential Loans
comprising or underlying the Trust Fund Assets. See "Yield Considerations" and
"Maturity and Prepayment Considerations."
 
     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 Certificates 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" and "--Principal Interest on the Securities."
 
BALLOON PAYMENTS
 
     Certain of the Residential Loans as of the Cut-off Date may not be fully
amortizing over their terms to maturity and, thus, will require principal
payments (i.e., balloon payments) at their stated maturity. Residential 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 Residential 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 Residential
Property, the financial condition of the borrower and tax laws.
 
NATURE OF MORTGAGES
 
     There are several factors that could adversely affect the value of the
Residential Properties such that the outstanding balance of the related
Residential Loans, together with any senior financing on the Residential
Properties, if applicable, would equal or exceed the value of the Residential
Properties. Among the factors that could adversely affect the value of the
Residential Properties are an overall decline in the residential real estate
market in the areas in which the Residential Properties are located or a decline
in the general condition of the Residential Properties as a result of failure of
borrowers to adequately maintain the Residential Properties or of natural
disasters that are not necessarily covered by insurance, such as earthquakes and
floods. In the case of Home Improvement Contracts or other Residential Loans
that are secured by junior liens, such decline could extinguish the value of the
interest of a junior mortgagee in the Residential 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
Residential Loans could be higher than those currently experienced in the
mortgage lending industry in general.
 
     Even assuming that the Residential Properties provide adequate security for
the Residential Loans, substantial delays could be encountered with the
liquidation of defaulted Residential Loans and corresponding delays in the
receipt of related proceeds by Securityholders could occur. An action to
foreclose on a Residential Property securing a Residential 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
Residential 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 Residential Property or to obtain liquidation
proceeds sufficient to repay all amounts due on the related Residential 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 Residential Loans and not yet reimbursed, including
payments to
 
                                       14
<PAGE>
senior lienholders, legal fees and costs of legal action, real estate taxes and
maintenance and preservation expenses.
 
     Liquidation expenses with respect to defaulted loans do not vary directly
with the outstanding principal balances 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 of the small loan than would be the case with the
defaulted loan having a large remaining principal balance. Since the mortgages
and deeds of trust securing certain Mortgage Loans, Multifamily Loans and 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 the 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 the senior mortgagees have been satisfied in full,
including any related foreclosure costs. In addition, a junior mortgagee may not
foreclose on the property securing a junior mortgage unless it forecloses
subject to any senior mortgage, in which case it 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. The Trust
Fund will not have any source of funds to satisfy any senior mortgages or make
payments due to any senior mortgagees, although the Master Servicer or
Sub-Servicer may, at its option, advance such amounts to the extent deemed
recoverable and prudent. In the event that such proceeds from a foreclosure or
similar sale of the related Mortgaged Property are insufficient to satisfy all
senior liens and the Mortgage Loan, Multifamily Loan or Home Improvement
Contract in the aggregate, the Trust Fund, as the holder of the junior lien,
and, accordingly, holders of one or more classes of the Securities, to the
extent not covered by credit enhancement, are likely to (i) incur losses in
jurisdictions in which a deficiency judgment against the borrower is not
available, and (ii) incur losses if any deficiency judgment obtained is not
realized upon. In addition, the rate of default of junior mortgage loans,
multifamily loans and home improvement contracts may be greater than that of
mortgage loans secured by first liens on comparable properties.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of certain originators and
servicers of Residential Loans. In addition, most states have other laws, public
policy and general principles of equity relating to the protection of consumers,
unfair and deceptive practices and practices which may apply to the origination,
servicing and collection of the Residential 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
Residential 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 Residential Loans."
 
ENVIRONMENTAL RISKS
 
     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 on a property, if agents or employees of the
lender have become sufficiently involved in the operations of the borrower,
regardless of whether the environmental damage or threat was caused by a prior
owner. A lender also risks such liability on foreclosure of the related
property. See "Risk Factors--Environmental Risks" and "Certain Legal Aspects of
Residential Loans--Environmental Legislation."
 
CERTAIN OTHER LEGAL CONSIDERATIONS REGARDING RESIDENTIAL LOANS
 
     The Residential 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 Residential Loans;
 
                                       15
<PAGE>
          (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 Residential Loans that were originated or closed after
     November 7, 1989, the Home Equity Loan Consumer Protection Act of 1988,
     which requires additional 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 are 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
upfront 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.
 
     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 protect the homeowner from defective
craftsmanship or incomplete work by a contractor. These laws permit the obligor
to withhold payment if the work does not meet the quality and durability
standards agreed to by the homeowner and the contractor. The Holder in Due
Course Rules have the effect of subjecting any assignee of the seller in a
consumer credit transaction to all claims and defenses which the obligor in the
credit sale transaction could assert against the seller of the goods.
 
     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 Residential Loans and in addition could subject the Trust Fund
to damages and administrative enforcement. See "Certain Legal Aspects of
Residential Loans."
 
RATING OF THE SECURITIES
 
     Unless otherwise specified in the related Prospectus Supplement, it will be
a condition to the issuance of a class of Securities 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 Trust Fund Assets and any credit
enhancement with respect to such class and such Rating Agency's assessment
solely of the likelihood that holders of a class of Securities 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 Residential Loans will be made, the degree to which
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.
 
     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 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
 
                                       16
<PAGE>
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 Residential Loans. No
assurance can be given that the values of any Residential Properties have
remained or will remain at their levels on the respective dates of origination
of the related Residential Loans. If the residential real estate markets should
experience an overall decline in property values such that the outstanding
principal balances of the Residential Loans in a particular Trust Fund and any
secondary financing on the related Residential Properties become equal to or
greater than the value of the Residential Properties, the rate 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 Residential
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. See "Rating."
 
BOOK-ENTRY REGISTRATION
 
     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 Certificates can be effected only through the Depository Trust
Company ("DTC"), participating organizations ("Participants"), Financial
Intermediaries and certain banks, the ability of a Certificateholder to pledge a
Certificate to persons or entities that do not participate in the DTC system, or
otherwise to take action in respect of such Securities, may be limited due to
lack of a physical certificate representing the Securities.
 
     In addition, Securityholders may experience some delay in their receipt of
distributions of interest and principal on the Certificates 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 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" herein.
 
CERTAIN HOME IMPROVEMENT CONTRACTS
 
     Contracts Unsecured.  The obligations of a borrower under an unsecured Home
Improvement Contract will not be secured by an interest in the related real
estate or otherwise, and the related Trust Fund, as the owner of such unsecured
Home Improvement Contract, will be a general unsecured creditor as to such
obligations. As a consequence, in the event of a default under an unsecured Home
Improvement Contract, the related Trust Fund will have recourse only against the
obligor's (the "Obligor") assets generally, along with all other general
unsecured creditors of the Obligor. In a bankruptcy or insolvency proceeding
relating to an Obligor on an unsecured Home Improvement Contract, the
obligations of the Obligor under such unsecured Home Improvement Contract may be
discharged in their entirety, notwithstanding the fact that the portion of such
Obligor's assets made available to the related Trust Fund as a general unsecured
creditor to pay amounts due and owing thereunder are sufficient to pay such
amounts in whole or part. An Obligor on an unsecured Home Improvement Contract
may not demonstrate the same degree of concern over performance of the Obligor's
obligations under such unsecured Home Improvement Contract as if such
obligations were secured by the real estate owned by such Obligor.
 
MORTGAGE LOANS UNDERWRITTEN AS NON-CONFORMING CREDITS MAY EXPERIENCE RELATIVELY
HIGHER LOSSES
 
     If so specified in the related Prospectus Supplement, the single family
Mortgage Loans assigned and transferred to the related Trust Fund may include
Mortgage Loans underwritten in accordance with the underwriting standards for
"non-conforming credits," which include borrowers whose creditworthiness and
repayment ability do not satisfy FNMA or FHLMC underwriting guidelines. A
Mortgage Loan made to a "non-conforming credit" means a residential loan that is
ineligible for purchase by FNMA or FHLMC due to borrower credit characteristics,
property characteristics, loan documentation guidelines or other characteristics
that do not meet FNMA or FHLMC underwriting guidelines, including a loan made to
a borrower whose creditworthiness
 
                                       17
<PAGE>
and repayment ability do not satisfy such FNMA or FHLMC underwriting guidelines
and a borrower who may have a record of major derogatory credit items such as
default on a prior residential loan, credit write-offs, outstanding judgments or
prior bankruptcies. Because the borrowers on such Mortgage Loans are less
creditworthy than borrowers who meet FNMA or FHLMC underwriting guidelines,
delinquencies and foreclosures can be expected to be more prevalent with respect
to such Mortgage Loans than with respect to residential loans originated in
accordance with FNMA or FHLMC underwriting guidelines. As a result, changes in
the values of the Mortgaged Properties may have a greater effect on the loss
experience of such Mortgage Loans than on residential loans originated in
accordance with FNMA or FHLMC underwriting guidelines. If the values of the
Mortgaged Properties decline after the dates of origination of such Mortgage
Loans, the rate of losses on such Mortgage Loans may increase and such increase
may be substantial. See "Residential Loan Program--Underwriting Standards."
 
TRUST FUND ASSETS MAY INCLUDE DELINQUENT AND SUB-PERFORMING RESIDENTIAL LOANS
 
     If so specified in the related Prospectus Supplement, the Trust Fund Assets
in the related Trust Fund may include Residential Loans that are delinquent or
sub-performing. Credit enhancement provided with respect to a particular Series
of Certificates may not cover all losses related to such delinquent or
sub-performing Residential Loans. Prospective investors should consider the risk
that the inclusion of such Residential Loans in the Trust Fund for a Series may
cause the rate of defaults and prepayments on the Residential Loans to increase
and, in turn, may cause losses to exceed the available credit enhancement for
such Series and affect the yield on the Securities of such Series. See "The
Trust Funds--Residential Loans."
 
PRE-FUNDING ACCOUNTS
 
     If so provided in the related Prospectus Supplement, on the Closing Date
the Depositor will deposit an amount (the "Pre-Funded Amount") specified in such
Prospectus Supplement into the Pre-Funding Account. The Pre-Funded Amount will
be used to purchase Residential Loans ("Subsequent Loans") within a period
commencing from the Closing Date and ending on a date not more than three months
after the 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). 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.
 
OTHER CONSIDERATIONS
 
     There is no assurance that the market value of the Trust Fund Assets or any
other assets of a Trust Fund will at any time be equal to or greater than the
principal amount of the Securities of the related Series then outstanding, plus
accrued interest thereon. Moreover, upon an event of default under the Agreement
for a Series and a sale of the assets in the Trust Fund 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.
 
RISKS ASSOCIATED WITH YEAR 2000 COMPLIANCE
 
     The Depositor is aware of the issues associated with the programming code
in existing computer systems as the millennium (year 2000) approaches, the "year
2000 problem" is pervasive and complex; virtually every computer operation will
be affected in some way by the rollover of the two digit year value to 00. The
issue is whether computer systems will properly recognize date-sensitive
information when the year changes to 2000. Systems that do not properly
recognize such information could generate erroneous data or cause a system to
fail. In the event that the computer systems of the Master Servicer or any
Special Servicer, with respect to any Series of Securities, are not fully year
2000 compliant, the resulting disruptions in the collection or distribution of
receipts on the related Mortgage Loans could materially adversely affect the
holders of the Securities.
 
                                       18
<PAGE>
                                THE TRUST FUNDS
 
     Each Trust Fund Asset will be selected by the Depositor for inclusion in a
Trust Fund from among those purchased, either directly or through affiliates,
from sellers not affiliated with the Depositor (any such sellers of Residential
Loans, hereinafter "Unaffiliated Sellers"), or, if provided in the related
Prospectus Supplement, from sellers affiliated with the Depositor.
 
RESIDENTIAL LOANS
 
     The Residential Loans will consist of mortgage loans (the "Mortgage Loans")
secured by first or junior liens on one- to four-family residential properties
(each, a "Mortgaged Property," collectively, "Mortgaged Properties") (which may
include Mortgage Securities) or mortgage loans (the "Multifamily Loans") secured
by first or junior liens on multifamily residential properties consisting of
five or more dwelling units (also, "Mortgaged Properties"), home improvement
installment sales contracts and installment loan agreements (the "Home
Improvement Contracts") which may be unsecured or secured by a lien on the
related Mortgaged Property or a Manufactured Home, which lien may be
subordinated to one or more senior liens on the related Mortgaged Property,
cooperative loans (the "Cooperative Loans") secured primarily by shares in the
related private cooperative housing corporation (a "Cooperative") that, with the
related proprietary lease or occupancy agreement, give the owner thereof the
right to occupy a particular dwelling unit (each, a "Cooperative Unit") in the
Cooperative or manufactured housing conditional sales contracts and installment
loan agreements (the "Manufactured Housing Contracts"), which may be secured by
either liens on (a) new or used Manufactured Homes or (b) the real property and
any improvements thereon (the "Mortgaged Property," which may include the
related Manufactured Home if deemed to be part of the real property under
applicable state law) relating to a Manufactured Housing Contract as well as in
certain cases a lien on a new or used Manufactured Home which is not deemed to
be a part of the related real property under applicable state law (such
Manufactured Housing Contracts that are secured by Mortgaged Property are
referred to herein as "Land Contracts"). The Mortgaged Properties, Cooperative
shares (together with the right to occupy a particular Cooperative Unit
evidenced thereby) and Manufactured Homes (collectively, the "Residential
Properties") may be located in any one of the fifty states, the District of
Columbia or the Commonwealth of Puerto Rico. Unless otherwise provided in the
related Prospectus Supplement, each Trust Fund will contain (and any
participation interest in any of the foregoing will relate to) only one of the
following types of Residential Loans:
 
          (1) Fully amortizing loans with a fixed rate of interest (such rate,
     an "Interest Rate") and level monthly payments to maturity;
 
          (2) Fully amortizing loans with a fixed Interest Rate providing for
     level monthly payments, or for payments of interest only during the early
     years of the term, followed by monthly payments of principal and interest
     that increase annually at a predetermined rate until the loan is repaid or
     for a specified number of years, after which level monthly payments resume;
 
          (3) Fully amortizing loans with a fixed Interest Rate providing for
     monthly payments during the early years of the term that are calculated on
     the basis of an interest rate below the Interest Rate, followed by monthly
     payments of principal and interest that increase annually by a
     predetermined percentage over the monthly payments payable in the previous
     year until the loan is repaid or for a specified number of years, followed
     by level monthly payments;
 
          (4) Fixed Interest Rate loans providing for level payments of
     principal and interest on the basis of an assumed amortization schedule and
     a balloon payment of principal at the end of a specified term;
 
          (5) Fully amortizing loans with an Interest Rate adjusted periodically
     ("ARM Loans") (with corresponding adjustments in the amount of monthly
     payments), to equal the sum (which may be rounded) of a fixed margin and an
     index as described in the related Prospectus Supplement, which may provide
     for an election, at the mortgagor's option during a specified period after
     origination of the loan, to convert the adjustable Interest Rate to a fixed
     Interest Rate, as described in the related Prospectus Supplement;
 
          (6) Fully amortizing loans with an adjustable Interest Rate providing
     for monthly payments less than the amount of interest accruing on such loan
     and for such amount of interest accrued but not paid currently to be added
     to the principal balance of such loan;
 
                                       19
<PAGE>
          (7) ARM Loans providing for an election at the mortgagor's option, in
     the event of an adjustment to the Interest Rate resulting in an Interest
     Rate in excess of the Interest Rate at origination of the loan, to extend
     the term to maturity for such period as will result in level monthly
     payments to maturity; or
 
          (8) Such other types of Residential Loans as may be described in the
     related Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, the Trust Fund
underlying a Series of Securities may include previously issued asset-backed
certificates, collateralized mortgage obligations or participation certificates
(each, and collectively, "Mortgage Securities"), evidencing interests in, or
collateralized by, Residential Loans or Agency Securities as described herein.
The Mortgage Securities may have been issued previously by the Depositor or an
affiliate thereof, a financial institution or other entity engaged generally in
the business of lending or a limited purpose corporation organized for the
purpose of, among other things, establishing trusts, acquiring and depositing
loans into such trusts, and selling beneficial interests in such trusts. If the
Mortgage Securities have been issued by an entity other than the Depositor or
its affiliates, such Mortgage Securities will have been (a) acquired in bona
fide secondary market transactions from persons other than the issuer thereof or
its affiliates and (b)(i) offered and distributed to the public pursuant to an
effective registration statement or (ii) purchased in a transaction not
involving any public offering from a person who is not an affiliate of the
issuer of such securities at the time of sale (nor an affiliate thereof at any
time during the preceding three months); provided, a period of two years elapsed
since the later of the date the securities were acquired from such issuer or
from an affiliate of the issuer. Except as otherwise set forth in the related
Prospectus Supplement, such Mortgage Securities will be generally similar to
Securities offered hereunder. As to any such Series of Securities, the related
Prospectus Supplement will include a description of such Mortgage Securities and
any related credit enhancement, and the Residential Loans underlying such
Mortgage Securities will be described together with any other Residential Loans
included in the Trust Fund relating to such Series. As to any such Series of
Securities, as used herein the term "Residential Loans" includes the Residential
Loans underlying such Mortgage Securities. Notwithstanding any other reference
herein to the Master Servicer, with respect to a Series of Securities as to
which the Trust Fund includes Mortgage Securities, the entity that services and
administers such Mortgage Securities on behalf of the holders of such Securities
may be referred to as the "Manager," if so specified in the related Prospectus
Supplement. References herein to advances to be made and other actions to be
taken by the Master Servicer in connection with the Residential Loans may
include such advances made and other actions taken pursuant to the terms of such
Mortgage Securities.
 
     If so specified in the related Prospectus Supplement, certain Residential
Loans may contain provisions prohibiting prepayments for a specified period
after their origination date (a "Lockout Period"), prohibiting prepayments
entirely or requiring the payment of a prepayment penalty upon prepayment in
full or in part.
 
     If so specified in the related Prospectus Supplement, the Trust Fund Assets
in the related Trust Fund may include Residential Loans that are delinquent or
sub-performing. The inclusion of such Residential Loans in the Trust Fund for a
Series may cause the rate of defaults and prepayments on the Residential Loans
to increase and, in turn, may cause losses to exceed the available credit
enhancement for such Series and affect the yield on the Certificates of such
Series.
 
MORTGAGE LOANS
 
     The Mortgage Loans will be evidenced by promissory notes (the "Mortgage
Notes") secured by mortgages or deeds of trust (the "Mortgages") creating first
or junior liens on the Mortgaged Properties. The Mortgage Loans will be secured
by one- to four-family residences, including detached and attached dwellings,
townhouses, rowhouses, individual condominium units, individual units in
planned-unit developments and individual units in de minimis planned-unit
developments. If so provided in the related Prospectus Supplement, the Mortgage
Loans will be insured by the FHA ("FHA Loans") or partially guaranteed by the VA
("VA Loans"). See "The Trust Funds--Residential Loans--FHA Loans and VA Loans"
and "Description of Primary Insurance Coverage--FHA Insurance and VA
Guarantees."
 
     Certain of the Mortgage Loans may be secured by junior liens, and the
related senior liens ("Senior Liens") may not be included in the mortgage pool.
The primary risk to holders of Mortgage Loans secured by junior liens is the
possibility that adequate funds will not be received in connection with a
foreclosure of the related Senior Liens to satisfy fully both the Senior Liens
and the Mortgage Loan. In the event that a holder of a Senior Lien
 
                                       20
<PAGE>
forecloses on a Mortgaged Property, the proceeds of the foreclosure or similar
sale will be applied first to the payment of court costs and fees in connection
with the foreclosure, second to real estate taxes, third in satisfaction of all
principal, interest, prepayment or acceleration penalties, if any, and any other
sums due and owing to the holder of the Senior Liens. The claims of the holders
of Senior Liens will be satisfied in full out of proceeds of the liquidation of
the Mortgage Loan, if such proceeds are sufficient, before the Trust Fund as
holder of the junior lien receives any payments in respect of the Mortgage Loan.
If the Master Servicer were to foreclose on any Mortgage Loan, it would do so
subject to any related Senior Liens. In order for the debt related to the
Mortgage Loan to be paid in full at such sale, a bidder at the foreclosure sale
of such Mortgage Loan would have to bid an amount sufficient to pay off all sums
due under the Mortgage Loan and the Senior Liens or purchase the Mortgaged
Property subject to the Senior Liens. In the event that such proceeds from a
foreclosure or similar sale of the related Mortgaged Property are insufficient
to satisfy all Senior Liens and the Mortgage Loan in the aggregate, the Trust
Fund, as the holder of the junior lien, and, accordingly, holders of one or more
classes of the Securities bear (i) the risk of delay in distributions while a
deficiency judgment against the borrower is obtained and (ii) the risk of loss
if the deficiency judgment is not realized upon. Moreover, deficiency judgments
may not be available in certain jurisdictions. In addition, a junior mortgagee
may not foreclose on the property securing a junior mortgage unless it
forecloses subject to the senior mortgages.
 
     Liquidation expenses with respect to defaulted junior mortgage loans do not
vary directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted junior mortgage loan having a small remaining principal balance
as it would in the case of a defaulted junior mortgage loan having a large
remaining principal balance, the amount realized after expenses of liquidation
would be smaller as a percentage of the outstanding principal balance of the
small junior mortgage loan than would be the case with the defaulted junior
mortgage loan having a large remaining principal balance. Because the average
outstanding principal balance of the Mortgage Loans is smaller relative to the
size of the average outstanding principal balance of the loans in a typical pool
of conventional first priority mortgage loans, liquidation proceeds may also be
smaller as a percentage of the principal balance of a Mortgage Loan than would
be the case in a typical pool of conventional first priority mortgage loans.
 
MULTIFAMILY LOANS
 
     The Multifamily Loans will be evidenced by Mortgage Notes secured by
Mortgages creating first or junior liens on rental apartment buildings or
projects containing five or more dwelling units. Unless otherwise specified in
the related Prospectus Supplement, Multifamily Loans will have had original
terms to stated maturity of not more than 30 years. If so provided in the
related Prospectus Supplement, the Multifamily Loans will be FHA Loans.
Mortgaged Properties which secure Multifamily Loans may include high-rise,
mid-rise and garden apartments. See "The Trust Funds--Residential Loans--FHA
Loans and VA Loans" and "Description of Primary Insurance Coverage--FHA
Insurance and VA Guarantees."
 
     If so provided in the related Prospectus Supplement, the Multifamily Loans
may contain provisions containing a Lockout Period, prohibiting prepayments
entirely or requiring the payment of a prepayment penalty upon prepayment in
full or in part. In the event that Securityholders will be entitled to all or a
portion of any prepayment penalties collected in respect of the related
Multifamily Loans, the related Prospectus Supplement will specify the method or
methods by which the prepayment penalties are calculated.
 
HOME EQUITY LOANS AND HOME IMPROVEMENT CONTRACTS
 
     As specified in the related Prospectus Supplement, the Home Equity Loans
will be secured by first or junior liens on the related Mortgaged Properties for
property improvement, debt consolidation or home equity purposes. The Home
Improvement Contracts will either be unsecured or secured by Mortgages on one-to
four-family, multifamily properties or manufactured housing which Mortgages are
generally subordinate to other mortgages on the same property. Except as
otherwise specified in the related Prospectus Supplement, the Home Improvement
Contracts will be fully amortizing and may have fixed or adjustable rates of
interest and may provide for other payment characteristics. Except as specified
in the related Prospectus Supplement, the home improvements relating to the Home
Equity Loans and Home Improvement Contracts may include replacement windows,
house siding, new roofs, swimming pools, satellite dishes, kitchen and bathroom
remodeling and solar heating panels. If so provided in the related Prospectus
Supplement certain of the Home Improvement Contracts
 
                                       21
<PAGE>
may be FHA Loans. See "The Trust Funds--Residential Loans--FHA Loans and VA
Loans" and "Description of Primary Insurance Coverage--FHA Insurance and VA
Guarantees."
 
COOPERATIVE LOANS
 
     The Cooperative Loans will be evidenced by promissory notes (the
"Cooperative Notes") secured by security interests in shares issued by
Cooperatives and in the related proprietary leases or occupancy agreements
granting exclusive rights to occupy specific Cooperative Units in the related
buildings.
 
MANUFACTURED HOUSING CONTRACTS
 
     The Manufactured Housing Contracts will consist of manufactured housing
conditional sales contracts and installment loan agreements each secured by a
Manufactured Home, or in the case of a Land Contract, by a lien on the real
estate to which the Manufactured Home is deemed permanently affixed and, in some
cases, the related Manufactured Home which is not real property under the
applicable state law. The Manufactured Homes securing the Manufactured Housing
Contracts will generally consist of manufactured homes within the meaning of 42
United States Code, Section 5402(6), which defines a "manufactured home" as "a
structure, transportable in one or more sections, which in the traveling mode,
is eight body feet or more in width or forty body feet or more in length, or,
when erected on site, is three hundred twenty or more square feet, and which is
built on a permanent chassis and designed to be used as a dwelling with or
without a permanent foundation when connected to the required utilities, and
includes the plumbing, heating, air conditioning, and electrical systems
contained therein; except that such term shall include any structure which meets
all the requirements of this paragraph except the size requirements and with
respect to which the manufacturer voluntarily files a certification required by
the Secretary of Housing and Urban Development and complies with the standards
established under this chapter."
 
     If so provided in the related Prospectus Supplement, the Manufactured
Housing Contracts may be FHA Loans or VA Loans. See "The Trust Funds--
Residential Loans--FHA Loans and VA Loans" and "Description of Primary Insurance
Coverage--FHA Insurance and VA Guarantees."
 
BUYDOWN LOANS
 
     If provided in the related Prospectus Supplement, certain of the
Residential Loans may be subject to temporary buydown plans ("Buydown Loans"),
pursuant to which the monthly payments made by the borrower in the early years
of the Buydown Loan (the "Buydown Period") will be less than the scheduled
payments on the Buydown Loan, the resulting difference to be made up from
(i) an amount contributed by the borrower, the seller of the Residential
Property or another source and placed in a custodial account and (ii) unless
otherwise specified in the related Prospectus Supplement, investment earnings on
the buydown funds. Generally, the borrower under each Buydown Loan will be
qualified at a reduced interest rate. Accordingly, the repayment of a Buydown
Loan is dependent on the ability of the borrower to make larger monthly payments
after the buydown funds have been depleted and, for certain Buydown Loans,
during the Buydown Period. See "Residential Loan Program--Underwriting
Standards."
 
FHA LOANS AND VA LOANS
 
     FHA Loans will be insured by the FHA as authorized under the National
Housing Act of 1934, as amended (the "Housing Act"), and the United States
Housing Act of 1937, as amended. One- to four-family FHA Loans will be insured
under various FHA programs including the standard FHA 203-b programs to finance
the acquisition of one- to four-family housing units and the FHA 245 graduated
payment mortgage program. Such FHA Loans generally require a minimum down
payment of approximately 5% of the original principal amount of the FHA Loan. No
FHA Loan may have an interest rate or original principal balance exceeding the
applicable FHA limits at the time of origination of such FHA Loan. See
"Description of Primary Insurance Coverage--FHA Insurance and VA Guarantees."
 
     Home Improvement Contracts and Manufactured Housing Contracts that are FHA
Loans are insured by the FHA (as described in the related Prospectus Supplement,
up to an amount equal to 90% of the sum of the unpaid principal of the FHA Loan,
a portion of the unpaid interest and certain other liquidation costs) pursuant
to Title I of the Housing Act.
 
                                       22
<PAGE>
     There are two primary FHA insurance programs that are available for
Multifamily FHA Loans. Sections 221(d)(3) and (d)(4) of the Housing Act allow
HUD to insure multifamily loans that are secured by newly constructed and
substantially rehabilitated multifamily rental projects. Section 244 of the
Housing Act provides for co-insurance of such loans made under Sections
221(d)(3) and (d)(4) by HUD/FHA and a HUD-approved co-insurer. Generally the
term of such a multifamily loan may be up to 40 years and the ratio of the loan
amount to property replacement cost can be up to 90%.
 
     Section 223(f) of the Housing Act allows HUD to insure multifamily loans
made for the purchase or refinancing of existing apartment projects that are at
least three years old. Section 244 also provides for co-insurance of mortgage
loans made under Section 223(f). Under Section 223(f), the loan proceeds cannot
be used for substantial rehabilitation work, but repairs may be made for up to,
in general, the greater of 15% of the value of the project and a dollar amount
per apartment unit established from time to time by HUD. In general the loan
term may not exceed 35 years and a loan-to-value ratio of no more than 85% is
required for the purchase of a project and 70% for the refinancing of a project.
 
     VA Loans will be partially guaranteed by the VA under the Servicemen's
Readjustment Act of 1944, as amended (the "Servicemen's Readjustment Act"). The
Servicemen's Readjustment Act permits a veteran (or in certain instances the
spouse of a veteran) to obtain a mortgage loan guarantee 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 purchasers and permits the guarantee of
mortgage loans of up to 30 years' duration. However, no VA Loan will have an
original principal amount greater than five times the partial VA guarantee for
such VA Loan. The maximum guarantee that may be issued by the VA under this
program will be set forth in the related Prospectus Supplement. See "Description
of Primary Insurance Coverage--FHA Insurance and VA Guarantees."
 
LOAN-TO-VALUE RATIO
 
     The "Loan-to-Value Ratio" of a Residential Loan at any given time is the
ratio, expressed as a percentage, of the then outstanding principal balance of
the Residential Loan, plus, in the case of a Mortgage Loan secured by a junior
lien, the outstanding principal balance of the related Senior Liens, to the
Collateral Value of the related Residential Property. Except as otherwise
specified in the Prospectus Supplement, the "Collateral Value" of a Residential
Property or Cooperative Unit, other than with respect to Refinance Loans, 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. "Refinance Loans" are loans made to refinance existing loans or loans
made to a borrower who was a tenant in a building prior to its conversion to
cooperative ownership. The "Collateral Value" of the Residential Property
securing a Refinance Loan is the appraised value thereof determined in an
appraisal obtained at the time of origination of the Refinance Loan. Unless
otherwise specified in the related Prospectus Supplement, for purposes of
calculating the Loan-to-Value Ratio of a Manufactured Housing Contract relating
to a new Manufactured Home, the Collateral Value is no greater than the sum of a
fixed percentage of the list price of the unit actually billed by the
manufacturer to the dealer (exclusive of freight to the dealer site) including
"accessories" identified in the invoice (the "Manufacturer's Invoice Price"),
plus the actual cost of any accessories purchased from the dealer, a delivery
and set-up allowance, depending on the size of the unit, and the cost of state
and local taxes, filing fees and up to three years prepaid hazard insurance
premiums. Unless otherwise specified in the related Prospectus Supplement, with
respect to used Manufactured Homes, the Collateral Value is the least of the
sales price, appraised value, and National Automobile Dealer's Association book
value plus prepaid taxes and hazard insurance premiums. The appraised value of a
Manufactured Home is based upon the age and condition of the manufactured
housing unit and the quality and condition of the mobile home park in which it
is situated, if applicable.
 
     Residential Properties may be subject to subordinate financing at the time
of origination. As is customary in residential lending, subordinate financing
may be obtained with respect to a Residential Property after the origination of
the Residential Loan without the lender's consent.
 
     No assurance can be given that values of the Residential Properties have
remained or will remain at their historic levels on the respective dates of
origination of the related Residential Loans. If the residential real estate
market were to experience an overall decline in property values such that the
outstanding principal balances of the Residential Loans, and any other financing
on the related Residential Properties, become equal to or greater
 
                                       23
<PAGE>
than the value of the Residential Properties, the actual rates of delinquencies,
foreclosures and losses may 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
borrowers of scheduled payments of principal and interest on the Residential
Loans and, accordingly, the actual rates of delinquencies, foreclosures and
losses. To the extent that such losses are not covered by the applicable
insurance policies and other forms of credit support described herein and in the
related Prospectus Supplement, such losses will be borne, at least in part, by
the holders of one or more classes of the Securities of the related Series. See
"Description of the Securities" and "Description of Credit Support."
 
AGENCY SECURITIES
 
     The Agency Securities will consist of any combination of "fully modified
pass-through" mortgage-backed certificates guaranteed by the GNMA ("GNMA
Certificates"), guaranteed mortgage pass-through securities issued by the FNMA
("FNMA Certificates") and mortgage participation certificates issued by the
FHLMC ("FHLMC Certificates").
 
GNMA
 
     GNMA is a wholly-owned corporate instrumentality of the United States
within the Department of Housing and Urban Development. Section 306(g) of Title
III of the Housing Act authorizes GNMA to guarantee the timely payment of the
principal of and interest on certificates that are based on and backed by a pool
of FHA Loans, VA Loans or by pools of other eligible residential loans.
 
     Section 306(g) of the Housing Act provides that "the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guaranty under this subsection." In order to meet
its obligations under such guaranty, GNMA is authorized, under
Section 306(d) of the Housing Act, to borrow from the United States Treasury
with no limitations as to amount, to perform its obligations under its
guarantee.
 
GNMA CERTIFICATES
 
     Each GNMA Certificate will be a "fully modified pass-through"
mortgage-backed certificate issued and serviced by an issuer approved by GNMA or
FNMA as a seller-servicer of FHA Loans or VA Loans, except as described below
with respect to Stripped Agency Securities (as defined below). The loans
underlying GNMA Certificates may consist of FHA Loans, VA Loans and other loans
eligible for inclusion in loan pools underlying GNMA Certificates. GNMA
Certificates may be issued under either or both of the GNMA I program and the
GNMA II program, as described in the related Prospectus Supplement. The
Prospectus Supplement for Certificates of each Series evidencing interests in a
Trust Fund including GNMA Certificates will set forth additional information
regarding the GNMA guaranty program, the characteristics of the pool underlying
such GNMA Certificates, the servicing of the related pool, the payment of
principal and interest on GNMA Certificates to the extent not described herein
and other relevant matters with respect to the GNMA Certificates.
 
     Except as otherwise specified in the related Prospectus Supplement or as
described below with respect to Stripped Agency Securities, each GNMA
Certificate will provide for the payment, by or on behalf of the issuer, to the
registered holder of such GNMA Certificate of monthly payments of principal and
interest equal to the holder's proportionate interest in the aggregate amount of
the monthly principal and interest payments on each related FHA Loan or VA Loan,
less servicing and guaranty fees aggregating the excess of the interest on such
FHA Loan or VA Loan over the GNMA Certificates pass-through rate. In addition,
each payment to a holder of a GNMA Certificate will include proportionate
pass-through payments to such holder of any prepayments of principal of the FHA
Loans or VA Loans underlying the GNMA Certificate and the holder's proportionate
interest in the remaining principal balance in the event of a foreclosure or
other disposition of any such FHA Loan or VA Loan.
 
     The GNMA Certificates do not constitute a liability of, or evidence any
recourse against, the issuer of the GNMA Certificates, the Depositor or any
affiliates thereof, and the only recourse of a registered holder, such as the
Trustee, is to enforce the guaranty of GNMA.
 
                                       24
<PAGE>
     GNMA will have approved the issuance of each of the GNMA Certificates
included in a Trust Fund in accordance with a guaranty agreement or contract
between GNMA and the issuer of such GNMA Certificates. Pursuant to such
agreement, such issuer, in its capacity as servicer, is required to perform
customary functions of a servicer of FHA Loans and VA Loans, including
collecting payments from borrowers and remitting such collections to the
registered holder, maintaining escrow and impoundment accounts of borrowers for
payments of taxes, insurance and other items required to be paid by the
borrower, maintaining primary hazard insurance, and advancing from its own funds
in order to make timely payments of all amounts due on the GNMA Certificate,
even if the payments received by such issuer on the loans backing the GNMA
Certificate are less than the amounts due thereon. If the issuer is unable to
make payments on a GNMA Certificate as they become due, it must promptly notify
GNMA and request GNMA to make such payment. Upon such notification and request,
GNMA will make such payments directly to the registered holder of the GNMA
Certificate. In the event no payment is made by the issuer and the issuer fails
to notify and request GNMA to make such payment, the registered holder of the
GNMA Certificate has recourse against only GNMA to obtain such payment. The
Trustee or its nominee, as registered holder of the GNMA Certificates included
in a Trust Fund, is entitled to proceed directly against GNMA under the terms of
the guaranty agreement or contract relating to such GNMA Certificates for any
amounts that are not paid when due under each GNMA Certificate.
 
     The GNMA Certificates included in a Trust Fund may have other
characteristics and terms, different from those described above so long as such
GNMA Certificates and underlying residential loans meet the criteria of the
Rating Agency or Agencies. Such GNMA Certificates and underlying residential
loans will be described in the related Prospectus Supplement.
 
FNMA
 
     FNMA is a federally chartered and stockholder-owned corporation organized
and existing under the Federal National Mortgage Association Charter Act, as
amended (the "Charter Act"). FNMA was originally established in 1938 as a United
States government agency to provide supplemental liquidity to the mortgage
market and was transformed into a stockholder-owned and privately managed
corporation by legislation enacted in 1968.
 
     FNMA provides funds to the mortgage market by purchasing mortgage loans
from lenders. FNMA acquires funds to purchase loans from many capital market
investors, thereby expanding the total amount of funds available for housing.
Operating nationwide, FNMA helps to redistribute mortgage funds from
capital-surplus to capital-short areas. In addition, FNMA issues mortgage-backed
securities primarily in exchange for pools of mortgage loans from lenders. FNMA
receives fees for its guaranty of timely payment of principal and interest on
its mortgage-backed securities.
 
FNMA CERTIFICATES
 
     FNMA Certificates are Guaranteed Mortgage Pass-Through Certificates
typically issued pursuant to a prospectus which is periodically revised by FNMA.
FNMA Certificates represent fractional undivided interests in a pool of mortgage
loans formed by FNMA. Each mortgage loan must meet the applicable standards of
the FNMA purchase program. Mortgage loans comprising a pool are either provided
by FNMA from its own portfolio or purchased pursuant to the criteria of the FNMA
purchase program. Mortgage loans underlying FNMA Certificates included in a
Trust Fund will consist of conventional mortgage loans, FHA Loans or VA Loans.
The Prospectus Supplement for Securities of each Series evidencing interests in
a Trust Fund including FNMA Certificates will set forth additional information
regarding the FNMA program, the characteristics of the pool underlying such FNMA
Certificates, the servicing of the related pool, payment of principal and
interest on the FNMA Certificates to the extent not described herein and other
relevant matters with respect to the FNMA Certificates.
 
     Except as described below with respect to Stripped Agency Securities, FNMA
guarantees to each registered holder of a FNMA Certificate that it will
distribute amounts representing such holder's proportionate share of scheduled
principal and interest at the applicable pass-through rate provided for by such
FNMA Certificate on the underlying mortgage loans, whether or not received, and
such holder's proportionate share of the full principal amount of any prepayment
or foreclosed or other finally liquidated mortgage loan, whether or not such
principal amount is actually recovered.
 
     The obligations of FNMA under its guarantees are obligations solely of FNMA
and are not backed by, nor entitled to, the full faith and credit of the United
States. If FNMA were unable to satisfy such obligations,
 
                                       25
<PAGE>
distributions to the holders of FNMA Certificates would consist solely of
payments and other recoveries on the underlying loans and, accordingly, monthly
distributions to the holders of FNMA Certificates would be affected by
delinquent payments and defaults on such loans.
 
     FNMA Certificates evidencing interests in pools of mortgage loans formed on
or after May 1, 1985 (other than FNMA Certificates backed by pools containing
graduated payment mortgage loans or multifamily loans) are available in
book-entry form only. With respect to a FNMA Certificate issued in book-entry
form, distributions thereon will be made by wire, and with respect to a fully
registered FNMA Certificate, distributions thereon will be made by check.
 
     The FNMA Certificates included in a Trust Fund may have other
characteristics and terms, different from those described above, so long as such
FNMA Certificates and underlying mortgage loans meet the criteria of the Rating
Agency or Rating Agencies rating the Certificates of such Series. Such FNMA
Certificates and underlying mortgage loans will be described in the related
Prospectus Supplement.
 
FHLMC
 
     FHLMC is a corporate instrumentality of the United States created pursuant
to Title III of the Emergency Home Finance Act of 1970, as amended (the "FHLMC
Act"). FHLMC was established primarily for the purpose of increasing the
availability of mortgage credit for the financing of needed housing. It seeks to
provide an enhanced degree of liquidity for residential mortgage investments
primarily by assisting in the development of secondary markets for conventional
mortgages. The principal activity of FHLMC currently consists of the purchase of
first lien, conventional residential mortgage loans or participation interests
in such mortgage loans and the resale of the mortgage loans so purchased in the
form of mortgage securities, primarily FHLMC Certificates. FHLMC is confined to
purchasing, so far as practicable, mortgage loans and participation interests
therein which it deems to be of such quality, type and class as to meet
generally the purchase standards imposed by private institutional mortgage
investors.
 
FHLMC CERTIFICATES
 
     Each FHLMC Certificate represents an undivided interest in a pool of
residential loans that may consist of first lien conventional residential loans,
FHA Loans or VA Loans ("FHLMC Certificate Group"). Each such mortgage loan must
meet the applicable standards set forth in the FHLMC Act. A FHLMC Certificate
Group may include whole loans, participation interests in whole loans and
undivided interests in whole loans and/or participations comprising another
FHLMC Certificate Group. The Prospectus Supplement for Securities of each Series
evidencing interests in a Trust Fund including FHLMC Certificates will set forth
additional information regarding the FHLMC guaranty program, the characteristics
of the pool underlying such FHLMC Certificate, the servicing of the related
pool, payment of principal and interest on the FHLMC Certificate to the extent
not described herein and other relevant matters with respect to the FHLMC
Certificates.
 
     Except as described below with respect to Stripped Agency Securities, FHLMC
guarantees to each registered holder of a FHLMC Certificate the timely payment
of interest on the underlying mortgage loans to the extent of the applicable
pass-through rate on the registered holder's pro rata share of the unpaid
principal balance outstanding on the underlying mortgage loans in the FHLMC
Certificate Group represented by such FHLMC Certificate, whether or not
received. FHLMC also guarantees to each registered holder of a FHLMC Certificate
collection by such holder of all principal on the underlying mortgage loans,
without any offset or deduction, to the extent of such holder's pro rata share
thereof, but does not, except if and to the extent specified in the related
Prospectus Supplement, guarantee the timely payment of scheduled principal.
Pursuant to its guarantees, FHLMC also guarantees ultimate collection of
scheduled principal payments, prepayments of principal and the remaining
principal balance in the event of a foreclosure or other disposition of a
mortgage loan. FHLMC may remit the amount due on account of its guarantee of
collection of principal at any time after default on an underlying mortgage
loan, but not later than 30 days following the latest of (i) foreclosure sale,
(ii) payment of the claim by any mortgage insurer and (iii) the expiration of
any right of redemption, but in any event no later than one year after demand
has been made upon the mortgagor for accelerated payment of principal. In taking
actions regarding the collection of principal after default on the mortgage
loans underlying FHLMC Certificates, including the timing of demand for
acceleration, FHLMC reserves the right to exercise its servicing judgment with
respect to the mortgage loans in the same manner as for mortgage loans which it
has purchased but not sold. The length of time necessary for FHLMC to determine
that a mortgage loan should be accelerated varies with the particular
 
                                       26
<PAGE>
circumstances of each mortgagor, and FHLMC has not adopted servicing standards
that require that the demand be made within any specified period.
 
     FHLMC Certificates are not guaranteed by the United States or by any
Federal Home Loan Bank and do not constitute debts or obligations of the United
States or any Federal Home Loan Bank. The obligations of FHLMC under its
guarantee are obligations solely of FHLMC and are not backed by, nor entitled
to, the full faith and credit of the United States. If FHLMC were unable to
satisfy such obligations, distributions to holders of FHLMC Certificates would
consist solely of payments and other recoveries on the underlying mortgage loans
and, accordingly, monthly distributions to holders of FHLMC Certificates would
be affected by delinquent payments and defaults on such Mortgage Loans.
 
     The FHLMC Certificates included in a Trust Fund may have other
characteristics and terms, different from those described above, so long as such
FHLMC Certificates and underlying mortgage loans meet the criteria of the Rating
Agency or Rating Agencies rating the Securities of such Series. Such FHLMC
Certificates and underlying mortgage loans will be described in the related
Prospectus Supplement.
 
STRIPPED AGENCY SECURITIES
 
     The GNMA Certificates, FNMA Certificates or FHLMC Certificates may be
issued in the form of certificates ("Stripped Agency Securities") which
represent an undivided interest in all or part of either the principal
distributions (but not the interest distributions) or the interest distributions
(but not the principal distributions), or in some specified portion of the
principal or interest distributions (but not all of such distributions), on an
underlying pool of mortgage loans or certain other GNMA Certificates, FNMA
Certificates or FHLMC Certificates. GNMA, FNMA or FHLMC, as applicable, will
guarantee each Stripped Agency Security to the same extent as such entity
guarantees the underlying securities backing such Stripped Agency Securities or
to the extent described above with respect to a Stripped Agency Security backed
by a pool of mortgage loans, unless otherwise specified in the related
Prospectus Supplement. The Prospectus Supplement for Securities of each Series
evidencing interests in a Trust Fund including Stripped Agency Securities will
set forth additional information regarding the characteristics of the assets
underlying such Stripped Agency Securities, the payments of principal and
interest on the Stripped Agency Securities and other relevant matters with
respect to the Stripped Agency Securities.
 
ADDITIONAL INFORMATION CONCERNING THE TRUST FUNDS
 
     Each Prospectus Supplement relating to a Series of Securities will contain
information, as of the date of such Prospectus Supplement, if applicable and to
the extent specifically known to the Depositor, with respect to the Residential
Loans or Agency Securities contained in the related Trust Fund, including, but
not limited to (i) the aggregate outstanding principal balance and the average
outstanding principal balance of the Trust Fund Assets as of the applicable
Cut-off Date, (ii) the types of related Residential Properties (e.g., one- to
four-family dwellings, multifamily residential properties, shares in
Cooperatives and the related proprietary leases or occupancy agreements,
condominiums and planned-unit development units, vacation and second homes and
new or used Manufactured Homes), (iii) the original terms to maturity, (iv) the
outstanding principal balances, (v) the origination dates, (vi) with respect to
Multifamily Loans, the Lockout Periods and prepayment penalties, (vii) the
loan-to-value ratios or, with respect to Residential Loans secured by a junior
lien, the combined loan-to-value ratios at origination, (viii) the Interest
Rates or range of Interest Rates borne by the Residential Loans or residential
loans underlying the Agency Securities, (ix) the geographical distribution of
the Residential Properties on a state-by-state basis, (x) the fixed Security
Interest Rate, or the initial Security Interest Rate in the case of a Series or
class of Securities with a variable or adjustable Security Interest Rate, (xi)
the number and aggregate principal balance of Buydown Loans, if any, (xii) the
Retained Interest, if any, (xiii) with respect to ARM Loans, the adjustment
dates, the highest, lowest and weighted average margin, and the maximum Interest
Rate variations at the time of adjustments and over the lives of the ARM Loans,
and (xiv) information as to the payment characteristics of the Residential
Loans. If specific information respecting the Trust Fund Assets is not known to
the Depositor at the time a Series of Securities is 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 a
report made available at or before the issuance of such Securities, which
information will be included in a report on Form 8-K which will be available to
purchasers of the related Securities at or before the initial issuance thereof
and will be filed with the Commission within fifteen days after the initial
issuance of such Securities. If
 
                                       27
<PAGE>
Mortgage Loans are added to or deleted from a Trust Fund after the date of the
related Prospectus Supplement, such addition or deletion will be noted in a
report on Form 8-K.
 
     The Depositor will cause the Residential Loans comprising each Trust Fund
(or Mortgage Securities evidencing interests therein) to be assigned to the
Trustee for the benefit of the holders of the Certificates of the related
Series. The Master Servicer will service the Residential Loans comprising any
Trust Fund, either directly or through other servicing institutions (each, a
"Sub-Servicer"), pursuant to a Pooling and Servicing Agreement or Servicing
Agreement among itself, the Depositor and the Trustee (each, a "Servicing
Agreement"), and will receive a fee for such services. See "Residential Loan
Program" and "Description of the Securities." With respect to Residential Loans
serviced through a Sub-Servicer, the Master Servicer will remain liable for its
servicing obligations under the related Servicing Agreement as if the Master
Servicer alone were servicing such Residential Loans.
 
     The Depositor will assign the Residential Loans to the related Trustee on a
non-recourse basis. Unless otherwise specified in the related Prospectus
Supplement, the obligations of the Depositor with respect to the Residential
Loans will be limited to certain representations and warranties made by it. See
"Description of the Securities--Assignment of Trust Fund Assets." The
obligations of the Master Servicer with respect to the Residential Loans will
consist principally of its contractual servicing obligations under the related
Servicing Agreement (including its obligation to enforce certain purchase and
other obligations of Sub-Servicers or Unaffiliated Sellers, or both, as more
fully described herein under "Residential Loan Program--Representations by
Unaffiliated Sellers; Repurchases"; "--Sub-Servicing" and "Description of the
Certificates--Assignment of Trust Fund Assets") and, unless otherwise provided
in the related Prospectus Supplement, its obligation to make certain cash
advances in the event of delinquencies in payments on or with respect to the
Residential Loans in amounts described herein under "Description of the
Certificates--Advances" or pursuant to the terms of any Mortgage Securities. Any
obligation of the Master Servicer to make advances may be subject to
limitations, to the extent provided herein and in the related Prospectus
Supplement.
 
     The Depositor will cause the Agency Securities comprising each Trust Fund
to be registered in the name of the Trustee or its nominee on the books of the
issuer or guarantor or its agent or, in the case of Agency Securities issued
only in book-entry form, through the Federal Reserve System, in accordance with
the procedures established by the issuer or guarantor for registration of such
certificates with a member of the Federal Reserve System, and distributions on
such securities to which the Trust Fund is entitled will be made directly to the
Trustee. The Trustee will administer the Trust Fund Assets comprising any Trust
Fund including Agency Securities pursuant to a Trust Agreement between the
Depositor and the Trustee, and will receive a fee for such service. The Agency
Securities and any moneys attributable to distributions on such Agency
Securities will not be subject to any right, charge, security interest, lien or
claim of any kind in favor of the Trustee or any person claiming through it. The
Trustee will not have the power or authority to assign, transfer, pledge or
otherwise dispose of any assets of any Trust Fund to any person, except to a
successor trustee, to the Depositor or the Securityholders to the extent they
are entitled thereto or to such other persons as may be specified in the related
Prospectus Supplement and except for its power and authority to invest assets of
the Trust Fund in Permitted Instruments (as hereinafter defined) in compliance
with the Trust Agreement. The Trustee will have no responsibility for
distributions on the Securities, other than to pass through all distributions
received with respect to the Agency Securities to the holders of the related
Securities without deduction, other than for any applicable trust administration
fee payable to the Trustee, certain expenses of the Trustee, if any, in
connection with legal actions relating to the Agency Securities, any applicable
withholding tax required to be withheld by the Trustee and as otherwise
described in the related Prospectus Supplement.
 
                                USE OF PROCEEDS
 
     The Depositor will apply all or substantially all of the net proceeds from
the sale of each Series of Securities for one or more of the following purposes:
(i) to purchase the related Trust Fund Assets, (ii) to repay indebtedness which
has been incurred to obtain funds to acquire such Trust Fund Assets, (iii) to
establish any Reserve Funds or other funds described in the related Prospectus
Supplement and (iv) to pay costs of structuring, guaranteeing and issuing such
Securities, including the costs of obtaining credit support, if any. If so
specified in the related Prospectus Supplement, the purchase of the Trust Fund
Assets for a Series may be effected by an exchange of Securities with the seller
of such Trust Fund Assets.
 
                                       28
<PAGE>
                              YIELD CONSIDERATIONS
 
     Unless otherwise specified in the related Prospectus Supplement, each
monthly or other periodic interest payment on a Trust Fund Asset is calculated
as one-twelfth of the applicable interest rate multiplied by the unpaid
principal balance thereof. The amount of such interest payment distributed (or
accrued in the case of Accrual Securities) to Securityholders (other than
holders of Strip Securities) with respect to each Trust Fund Asset will be
similarly calculated for the applicable period, based on the applicable Security
Interest Rate. In the case of Strip Securities, except as otherwise described in
the related Prospectus Supplement, such distributions of Stripped Interest will
be made in the manner and amount described in the related Prospectus Supplement.
The Securities of each Series may bear a fixed, variable or adjustable Security
Interest Rate.
 
     The effective yield to Securityholders will be below the yield otherwise
produced by the applicable Security Interest Rate (or as to a Strip Security,
the distributions of interest thereon ("Stripped Interest")) and purchase price
paid by the investors, because while interest will accrue on each Trust Fund
Asset from the first day of each month (unless otherwise provided in the related
Prospectus Supplement), the distribution of such interest (or the accrual
thereof in the case of Accrual Securities) will not be made until the
Distribution Date occurring in the month or other periodic interval (as
specified in the related Prospectus Supplement) following the month or other
period of accrual in the case of Residential Loans, and in later months in the
case of Agency Securities and in the case of a Series of Securities having
Distribution Dates occurring at intervals less frequently than monthly.
 
     Unless otherwise provided in the related Prospectus Supplement, when a full
prepayment is made on a Residential Loan, the borrower is charged interest only
for the number of days actually elapsed from the due date of the preceding
monthly payment up to the date of such prepayment, instead of for a full month
and accordingly, the effect of such prepayments is to reduce the aggregate
amount of interest collected that is available for distribution to
Securityholders. However, if so provided in the related Prospectus Supplement,
certain of the Residential Loans may contain provisions limiting prepayments
thereof or requiring the payment of a prepayment penalty upon prepayment in full
or in part. Unless otherwise provided in the Prospectus Supplement, the
prepayment penalty collected with respect to the Residential Loans will be
applied to offset such shortfalls in interest collections on the related
Distribution Date. Holders of Agency Securities are entitled to a full month's
interest in connection with prepayments in full of the underlying residential
loans. Unless otherwise specified in the related Prospectus Supplement, partial
principal prepayments are applied on the first day of the month following
receipt, with no resulting reduction in interest payable by the borrower for the
month in which the partial principal prepayment is made. Unless provided
otherwise in the related Prospectus Supplement, neither the Trustee, the Master
Servicer nor the Depositor will be obligated to fund shortfalls in interest
collections resulting from full prepayments. Full and partial prepayments
collected during the applicable Prepayment Period will be available for
distribution to Securityholders on the related Distribution Date. Unless
otherwise provided in the related Prospectus Supplement, a "Prepayment Period"
in respect of any Distribution Date will commence in the case of Distribution
Dates that occur monthly, on the first day of the preceding calendar month and,
in the case of Distribution Dates that occur less frequently than monthly, on
the first day of the month in which the immediately preceding Distribution Date
occurred (or, with respect to the first Prepayment Period, the Cut-off Date) and
will end in both cases on the last day of the preceding calendar month. See
"Maturity and Prepayment Considerations" and "Description of the Securities."
 
     Even assuming that the Mortgaged Properties provide adequate security for
the Mortgage Loans, substantial delays could be encountered in connection with
the liquidation of defaulted Mortgaged Loans and corresponding delays in the
receipt of related proceeds by Securityholders could occur. An action to
foreclose on a Mortgaged Property securing a Mortgaged 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
Mortgaged Property or to obtain liquidation proceeds sufficient to repay all
amounts due on the related Mortgaged 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 Mortgaged Loans and
not yet reimbursed, including payments to senior lienholders, legal fees and
costs of legal action, real estate taxes and maintenance and preservation
expenses.
 
                                       29
<PAGE>
     Liquidation expenses with respect to defaulted mortgage loans do not vary
directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer 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 Residential Loans. In addition, most have other laws, public policy
and general principles of equity relating to the protection of consumers, unfair
and deceptive practices and practices which may apply to the origination,
servicing and collection of the Residential 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
Residential Loans, may entitle the borrower to a refund of amounts previously
paid and, in addition, could subject the Trustee or Master Servicer to damages
and administrative sanctions which could reduce the amount of distributions
available to holders of the Certificates.
 
     The Prospectus Supplement for each Series of Securities may set forth
additional information regarding yield considerations.
 
                     MATURITY AND PREPAYMENT CONSIDERATIONS
 
     The original terms to maturity of the Trust Fund Assets in a given Trust
Fund may vary depending upon the type of Residential Loans or the residential
loans underlying the Agency Securities included therein. Each Prospectus
Supplement will contain information with respect to the type and maturities of
the Trust Fund Assets in the related Trust Fund. Unless otherwise specified in
the related Prospectus Supplement, the Residential Loans or residential loans
underlying the Agency Securities may be prepaid in full or in part at any time
without penalty. The prepayment experience on the Residential Loans or
residential loans underlying the Agency Securities will affect the life of the
related Securities. The average life of a Security refers to the average amount
of time that will elapse from the date of issuance of a Security until the
principal amount of such Security has been reduced to zero. The average life of
the Securities will be affected by, among other things, the rate at which
principal on the related Residential Loans is paid, which may be in the form of
scheduled amortization payments or unscheduled prepayments and liquidations due
to default, casualty, insurance, condemnation and similar sources. If
substantial principal prepayments on the Residential Loans are received, the
actual average life of the Securities may be significantly shorter than would
otherwise be the case. As to any Series of Securities, based on the public
information with respect to the residential lending industry, it may be
anticipated that a significant number of the related Residential Loans will be
paid in full prior to stated maturity.
 
     Prepayments on residential loans are commonly measured relative to a
prepayment standard or model. For certain Series of Securities comprised of more
than one class, or as to other types of Series where applicable, the Prospectus
Supplement will describe the prepayment standard or model used in connection
with the offering of such Series and, if applicable, will contain tables setting
forth the projected weighted average life of the Securities of such Series and
the percentage of the initial Security Principal Balance that would be
outstanding on specified Distribution Dates based on the assumptions stated in
the Prospectus Supplement, including assumptions that prepayments on the related
Residential Loans or residential loans underlying the Agency Securities are made
at rates corresponding to various percentages of the prepayment standard or
model specified in the Prospectus Supplement.
 
     It is unlikely that prepayment of the Trust Fund Assets will conform to any
model specified in the related Prospectus Supplement. The rate of principal
prepayments on pools of residential loans is influenced by a variety of
economic, social, geographic, demographic and other factors, including homeowner
mobility, economic conditions, enforceability of due-on-sale clauses, market
interest rates and the availability of funds, the existence of lockout
provisions and prepayment penalties, the inclusion of delinquent or
sub-performing Residential Loans in the Trust Fund Assets, the relative tax
benefits associated with the ownership of property and, in the case of
Multifamily Loans, the quality of management of the property. The rate of
prepayments of conventional residential loans has fluctuated significantly in
recent years. In general, however, if prevailing interest rates fall
 
                                       30
<PAGE>
significantly below the interest rates on the Trust Fund Assets, such Trust Fund
Assets are likely to be the subject of higher principal prepayments than if
prevailing rates remain at or above the interest rates borne by such Trust Fund
Assets.
 
     Other factors that might be expected to affect the prepayment rate of
Securities backed by junior lien 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. In addition, any future limitations on
the right of borrowers to deduct interest payments on junior liens that are home
equity loans for federal income tax purposes may increase the rate of
prepayments on such Residential Loans.
 
     In addition, acceleration of payments on the Residential Loans or
residential loans underlying the Agency Securities as a result of certain
transfers of the underlying properties is another factor affecting prepayment
rates. Unless otherwise provided in the related Prospectus Supplement, all
Residential Loans, except for FHA Loans and VA Loans, will contain "due-on-sale"
provisions permitting the lender to accelerate the maturity of the Residential
Loan upon sale or certain transfers by the borrower with respect to the
underlying Residential Property. Conventional residential loans that underlie
FHLMC Certificates and FNMA Certificates may contain, and in certain cases must
contain, "due-on-sale" clauses permitting the lender to accelerate the unpaid
balance of the loan upon transfer of the property by the borrower. FHA Loans and
VA Loans and all residential loans underlying GNMA Certificates contain no such
clause and may be assumed by the purchaser of the property. In addition,
Multifamily Loans may contain "due-on-encumbrance" clauses permitting the lender
to accelerate the maturity of the Multifamily Loan upon further encumbrance by
the borrower of the underlying Residential Property. In general, where a
"due-on-sale" or "due-on-encumbrance" clause is contained in a conventional
residential loan under a FHLMC or the FNMA program, the lender's right to
accelerate the maturity of the residential loan upon transfer or further
encumbrance of the property must be exercised, so long as such acceleration is
permitted under applicable law.
 
     With respect to a Series of Securities evidencing interests in a Trust Fund
including Residential Loans, unless otherwise provided in the related Prospectus
Supplement, the Master Servicer generally will enforce any provision limiting
prepayments and any due-on-sale or due-on-encumbrance clause, to the extent it
has knowledge of the conveyance or encumbrance or the proposed conveyance or
encumbrance of the underlying Residential 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 "Description of the
Securities--Collection and Other Servicing Procedures" and "Certain Legal
Aspects of Residential Loans--Enforceability of Certain Provisions" and
"Prepayment Charges and Prepayments" for a description of certain provisions of
each Pooling and Servicing Agreement and certain legal developments that may
affect the prepayment experience on the Residential Loans. See also "Description
of the Securities--Termination" for a description of the possible early
termination of any Series of Securities. See also "Residential Loan
Program--Representations by Unaffiliated Sellers; Repurchases" and "Description
of the Securities--Assignment of Trust Fund Assets" for a description of the
obligation of the Unaffiliated Sellers, the Master Servicer and the Depositor to
repurchase Residential Loans under certain circumstances.
 
     With respect to a Series of Securities evidencing interests in a Trust Fund
including Agency Securities, principal prepayments may also result from guaranty
payments and from the exercise by the issuer or guarantor of the related Agency
Securities of any right to repurchase the underlying residential loans. The
Prospectus Supplement relating to each Series of Securities will describe the
circumstances and the manner in which such optional repurchase right, if any,
may be exercised.
 
     In addition, certain Mortgage Securities included in the Trust Fund may be
backed by underlying Residential Loans having differing interest rates.
Accordingly, the rate at which principal payments are received on the related
Securities will, to a certain extent, depend on the interest rates on such
underlying Residential Loans.
 
     The Prospectus Supplement for each Series of Securities may set forth
additional information regarding related maturity and prepayment considerations.

<PAGE>
                                 THE DEPOSITOR
 
     PaineWebber Mortgage Acceptance Corporation IV, the Depositor, is a
Delaware corporation organized on April 23, 1987, as a wholly-owned limited
purpose finance subsidiary of PaineWebber Group Inc. The Depositor maintains its
principal office at 1285 Avenue of the Americas, New York, New York. Its
telephone number is (212) 713-2000.
 
     The Depositor does not have, nor is it expected in the future to have, any
significant assets. It is not expected that the Depositor will have any business
operations other than acquiring and pooling residential loans and agency
securities, offering Certificates of the type described herein or other
mortgage- or asset-related securities, and related activities.
 
     Neither the Depositor nor any of the Depositor's affiliates will insure or
guarantee distributions on the Securities of any Series.
 
                            RESIDENTIAL LOAN PROGRAM
 
     The Residential Loans will have been purchased by the Depositor, either
directly or through affiliates, from sellers. Unless otherwise specified in the
related Prospectus Supplement, all Residential Loans will have been originated
in general accordance with the criteria specified below. The underwriting
standards applicable to Residential Loans underlying Mortgage Securities may
vary substantially from the underwriting standards set forth below.
 
UNDERWRITING STANDARDS
 
     Unless otherwise specified in the related Prospectus Supplement, each
seller will represent and warrant that all Residential Loans originated and/or
sold by it to the Depositor or one of its affiliates will have been underwritten
in general accordance with standards consistent with those utilized by mortgage
lenders generally during the period of origination for similar types of loans.
As to any Residential Loan insured by the FHA or partially guaranteed by the VA,
the seller will represent that it has complied with underwriting policies of the
FHA or the VA, as the case may be.
 
     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 Residential Property as collateral. In general, a prospective borrower
applying for a Residential 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. Unless otherwise specified in the related Prospectus
Supplement, a verification of the borrower's income will be obtained from an
independent source and, 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.
Unless otherwise specified in the related Prospectus Supplement, an employment
verification is obtained from an independent source (typically the borrower's
employer) which verification reports the length of employment with that
organization, the current salary, and whether it is expected that the borrower
will continue such employment in the future. If a prospective borrower is
self-employed, the borrower may be required to submit copies of signed tax
returns. The borrower may also be required to authorize verification of deposits
at financial institutions where the borrower has demand, savings or brokerage
accounts.
 
     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 that construction, if new, has been
completed. The appraisal is based on the market value of comparable homes, the
estimated rental income (if considered applicable by the appraiser) and the cost
of replacing the home.
 
     Once all applicable employment, credit and property information is
received, a determination generally is made as to whether the prospective
borrower has sufficient monthly income available (i) to meet the borrower's
monthly obligations on the proposed mortgage loan (generally determined on the
basis of the monthly payments due in the year of origination) and other expenses
related to the property (such as property taxes and hazard
 
                                       32
<PAGE>
insurance) and (ii) to meet monthly housing expenses and other financial
obligations and monthly living expenses. The underwriting standards applied by
Sellers, particularly with respect to the level of loan documentation and the
mortgagor's income and credit history, may be varied in appropriate cases where
factors such as low loan-to-value ratios, or combined-loan-to-value ratios, as
applicable, or other favorable and compensating credit factors exist.
 
     The underwriting guidelines with respect to some Unaffiliated Sellers' loan
programs may be less stringent than those of FNMA or FHLMC, primarily in that
they generally may permit the borrower to have a higher debt-to-income ratio and
a larger number of derogatory credit items than do the guidelines of FNMA or
FHLMC. These underwriting guidelines are intended to provide for the origination
of single family mortgage loans for non-conforming credits. A mortgage loan made
to a "non-conforming credit" means a mortgage loan that is ineligible for
purchase by FNMA or FHLMC due to borrower credit characteristics that do not
meet FNMA or FHLMC underwriting guidelines, including a loan made to a borrower
whose creditworthiness and repayment ability do not satisfy such FNMA or FHLMC
underwriting guidelines or a borrower who may have a record of major derogatory
credit items such as default on a prior mortgage loan, credit write-offs,
outstanding judgments and prior bankruptcies. Accordingly, Mortgage Loans
underwritten pursuant to these guidelines are likely to experience rates of
delinquency and foreclosure that are higher, and may be substantially higher,
than mortgage loans originated in accordance with FNMA or FHLMC underwriting
guidelines.
 
QUALIFICATIONS OF UNAFFILIATED SELLERS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Unaffiliated Seller will be required to satisfy the qualifications set forth
herein. Each Unaffiliated Seller must be an institution experienced in
originating and servicing the types of residential loans sold by it for
inclusion in a Trust Fund 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 Unaffiliated Seller must be a seller/servicer approved by either FNMA or
FHLMC, and must be a mortgagee approved by the FHA or an institution the deposit
accounts in which are insured by the Bank Insurance Fund ("BIF") or Savings
Association Insurance Fund ("SAIF") of the Federal Deposit Insurance Corporation
(the "FDIC"). In addition, each Unaffiliated Seller must satisfy certain
criteria as to financial stability evaluated on a case by case basis by the
Depositor.
 
REPRESENTATIONS BY UNAFFILIATED SELLERS; REPURCHASES
 
     Each Unaffiliated Seller will have made representations and warranties in
respect of the Residential Loans sold by such Unaffiliated Seller. Unless
otherwise provided in the related Prospectus Supplement, such representations
and warranties include, among other things: (i) that title insurance (or in the
case of Residential Properties located in areas where such policies are
generally not available, an attorney's certificate of title) and any FHA
insurance, VA guarantee and any required hazard and primary credit insurance was
effective at the origination of each Residential Loan, and that each policy (or
certificate of title) remained in effect on the date of purchase of the
Residential Loan from the Unaffiliated Seller by or on behalf of the Depositor;
(ii) that the Unaffiliated Seller had good title to each such Residential Loan
and such Residential Loan was subject to no offsets, defenses, counterclaims or
rights of rescission except to the extent that any buydown agreement described
herein may forgive certain indebtedness of a borrower; (iii) if the Trust Fund
includes Mortgage Loans, that each Mortgage constituted a valid lien on the
Mortgaged Property (subject only to permissible title insurance exceptions and
Senior Liens, if any); (iv) if the Trust Fund includes Manufactured Housing
Contracts, each Manufactured Housing Contract creates a valid, subsisting and
enforceable first priority security interest in the Manufactured Home covered
thereby; (v) that the Residential Property was free from damage and was in good
repair; (vi) that there were no delinquent tax or assessment liens against the
Residential Property; (vii) that each Residential Loan was current as to all
required payments; and (viii) that each Residential Loan was made in compliance
with, and is enforceable under, all applicable local, state and federal laws and
regulations in all material respects.
 
     In certain cases, the representations and warranties of an Unaffiliated
Seller in respect of a Residential Loan may have been made as of the date on
which such Unaffiliated Seller sold the Residential Loan to the Depositor or its
affiliate. A substantial period of time may have elapsed between such date and
the date of initial issuance of
 
                                       33
<PAGE>
the Series of Securities evidencing an interest in such Residential Loan. Since
the representations and warranties of an Unaffiliated Seller do not address
events that may occur following the sale of a Residential Loan by such
Unaffiliated Seller, its repurchase obligation described below will not arise if
the relevant event that would otherwise have given rise to such an obligation
occurs after the date of such sale to or on behalf of the Depositor.
 
     The only representations and warranties, if any, to be made for the benefit
of holders of Securities in respect of any Residential Loan relating to the
period commencing on the date of sale of such Residential Loan to the Depositor
or its affiliates will be certain limited representations of the Depositor and
of the Master Servicer described below under "Description of the
Securities--Assignment of Trust Fund Assets." If the Master Servicer is also an
Unaffiliated Seller of Residential Loans with respect to a particular Series,
such representations will be in addition to the representations and warranties
made by the Master Servicer in its capacity as an Unaffiliated Seller.
 
     The Master Servicer will promptly notify the relevant Unaffiliated Seller
of any breach of any representation or warranty made by it in respect of a
Residential Loan which materially and adversely affects the interests of the
Securityholders in such Residential Loan. If such Unaffiliated Seller cannot
cure such breach within 60 days (or such other time period set forth in the
related Prospectus Supplement) from the date on which the Unaffiliated Seller
was notified of such breach, then such Unaffiliated Seller will be obligated to
repurchase such Residential Loan from the Trustee within 90 days (or such other
time period set forth in the related Prospectus Supplement) from the date on
which the Unaffiliated Seller was notified of such breach, at the Purchase Price
therefor. As to any Residential Loan, unless otherwise specified in the related
Prospectus Supplement, the "Purchase Price" is equal to the sum of (i) the
unpaid principal balance thereof, (ii) unpaid accrued interest on the Stated
Principal Balance (as defined below) from the date as to which interest was last
paid by the borrower to the end of the calendar month in which the purchase is
to occur at a rate equal to the Net Mortgage Rate minus the rate at which the
Sub-Servicer's servicing fee is calculated if the Sub-Servicer is the purchaser,
(iii) any unpaid servicing fees and certain unreimbursed servicing expenses
payable or reimbursable to the Master Servicer with respect to such Residential
Loan, (iv) any unpaid Retained Interest with respect to such Residential Loan,
(v) any Realized Losses incurred with respect to such Residential Loan, as
described below under "Description of the Certificates--Subordination," and
(vi) if applicable, any expenses reasonably incurred or to be incurred by the
Master Servicer or the Trustee in respect of the breach or defect giving rise to
a purchase obligation. If so provided in the related Prospectus Supplement, an
Unaffiliated Seller, rather than repurchase a Residential Loan as to which a
breach has occurred, will have the option, within a specified period after
initial issuance of the related Series of Securities, to cause the removal of
such Residential Loan from the Trust Fund and substitute in its place one or
more other Residential Loans, in accordance with the standards described in the
related Prospectus Supplement. The Master Servicer or the Trustee, unless
otherwise specified in the related Prospectus Supplement, will be required under
the applicable Servicing Agreement to use its best efforts to enforce such
obligations of the Unaffiliated Seller 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 Residential Loan. Unless
otherwise specified in the related Prospectus Supplement, this repurchase or
substitution obligation will constitute the sole remedy available to holders of
Certificates or the Trustee for a breach of representation by an Unaffiliated
Seller. For each Series with respect to which a REMIC election is to be made,
unless the related Prospectus Supplement provides otherwise, the Master Servicer
will be obligated to pay any prohibited transaction tax which may arise in
connection with such repurchase or substitution. See "Description of the
Certificates--General."
 
     The "Stated Principal Balance" of any Mortgage Loan as of any date of
determination is equal to the principal balance thereof as of the Cut-off Date,
after application of all scheduled principal payments due on or before the
Cut-off Date, whether or not received, reduced by all amounts, including
advances by the Master Servicer, allocable to principal that are distributed to
Securityholders on or before the date of determination, and as further reduced
to the extent that any Realized Loss (as hereinafter defined) thereon has been
(or, if it had not been covered by any form of credit support, would have been)
allocated to one or more class of Securities on or before the date of
determination.
 
     Neither the Depositor nor the Master Servicer (unless the Master Servicer
is an Unaffiliated Seller) will be obligated to purchase or substitute for a
Residential Loan if an Unaffiliated Seller defaults on its obligation to do so,
and no assurance can be given that Unaffiliated Sellers will carry out such
obligations with respect to
 
                                       34
<PAGE>
Residential Loans. To the extent that a breach of the representations and
warranties of an Unaffiliated Seller also constitutes a breach of a
representation made by the Depositor, the Depositor may have a repurchase or
substitution obligation as described below under "Description of the
Securities--Assignment of Trust Fund Assets." Any Residential Loan that is not
repurchased or substituted for shall remain in the related Trust Fund and any
losses thereon shall be borne by Securityholders, to the extent not covered by
credit enhancement.
 
SUB-SERVICING
 
     Any Master Servicer may delegate its servicing obligations in respect of a
Residential Loan to Sub-Servicers pursuant to a sub-servicing agreement (a
"Sub-Servicing Agreement"), which will be consistent with the terms of the
Servicing Agreement relating to the Trust Fund that includes such Residential
Loan. Although each Sub-Servicing Agreement will be a contract solely between
the Master Servicer and the Sub-Servicer, the Pooling and Servicing Agreement
pursuant to which a Series of Securities is issued will provide that, if for any
reason the Master Servicer for such Series of Securities is no longer acting in
such capacity, the Trustee or any successor Master Servicer must recognize the
Sub-Servicer's rights and obligations under such Sub-Servicing Agreement.
 
     With the approval of the Master Servicer, a Sub-Servicer may delegate its
servicing obligations to third-party servicers, but such Sub-Servicer will
remain primarily liable for such obligations under the related Sub-Servicing
Agreement. Each Sub-Servicer will be required to perform the customary functions
of a servicer of residential loans, including collecting payments from borrowers
and remitting such collections to the Master Servicer; maintaining FHA
insurance, any VA guarantee, and primary hazard and credit insurance as
described herein and in any related Prospectus Supplement, and filing and
settling claims thereunder, subject in certain cases to the right of the Master
Servicer to approve in advance any such settlement; maintaining escrow or
impoundment accounts of borrowers for payment of taxes, insurance and other
items required to be paid by the borrower pursuant to the Residential Loan;
processing assumptions or substitutions, although, unless otherwise specified in
the related Prospectus Supplement, the Master Servicer generally is required to
exercise due-on-sale and due-on-encumbrance clauses to the extent such exercise
is permitted by law and would not adversely affect insurance coverage;
attempting to cure delinquencies; effecting foreclosures or repossessions;
inspecting and managing Residential Properties under certain circumstances; and
maintaining accounting records relating to the Residential Loans. The Master
Servicer will be responsible for filing and settling claims in respect of
Residential Loans in a particular Trust Fund under any applicable pool insurance
policy, bankruptcy bond, special hazard insurance policy or letter of credit.
See "Description of Credit Support." To the extent specified in the related
Prospectus Supplement, a Sub-Servicer will also be obligated to make advances in
respect of delinquent installments of principal and interest on Residential
Loans, as described more fully under "Description of the Securities--Payments on
Residential Loans" and "--Deposits to Certificate Account," and in respect of
certain taxes and insurance premiums not paid on a timely basis by borrowers.
 
     As compensation for its servicing duties, each Sub-Servicer will be
entitled to a monthly servicing fee (to the extent the related Residential Loan
payment has been collected) in the amount set forth in the related Prospectus
Supplement. Each Sub-Servicer is also entitled to collect and retain, as part of
its servicing compensation late charges provided in the Mortgage Note,
Cooperative Note or Manufactured Housing Contract or related instruments. If so
provided in the related Prospectus Supplement, a Sub-Servicer may be entitled to
any prepayment penalties and a Retained Interest in certain Residential Loans.
Each Sub-Servicer will be reimbursed by the Master Servicer for certain
expenditures which it makes, generally to the same extent the Master Servicer
would be reimbursed under a Pooling and Servicing Agreement. See "Description of
the Securities--Retained Interest, Administration Compensation and Payment of
Expenses."
 
     Each Sub-Servicer may be required to agree to indemnify the Master Servicer
for any liability or obligation sustained by the Master Servicer in connection
with any act or failure to act by the Sub-Servicer in its servicing capacity.
Unless otherwise provided in the related Prospectus Supplement, each
Sub-Servicer is required to maintain a fidelity bond and an errors and omissions
policy with respect to its officers, employees and other persons acting on its
behalf or on behalf of the Master Servicer.

<PAGE>
                         DESCRIPTION OF THE SECURITIES
 
     The Certificates of each Series evidencing interests in a Trust Fund
including Residential Loans will be issued pursuant to a separate Pooling and
Servicing Agreement among the Depositor, the Master Servicer and the Trustee and
the Securities of each Series evidencing interests in a Trust Fund including
Agency Securities will be issued pursuant to a separate Trust Agreement ("Trust
Agreement") between the Depositor and the Trustee. Each Series of Notes (or, in
certain instances, two or more Series of Notes) will be issued pursuant to an
Indenture between the related Issuer and the Trustee. The related Trust Fund
will be created pursuant to an Owner Trust Agreement (the "Owner Trust
Agreement"; an Owner Trust Agreement, Pooling and Servicing Agreement, Servicing
Agreement, Indenture, an "Agreement") between the Depositor and the Owner
Trustee. As to each Series of Notes where the Issuer is an Owner Trust, the
ownership of the Trust Fund will be evidenced by certificates (the "Equity
Certificates") issued under the Owner Trust Agreement, which, unless otherwise
specified in the Prospectus Supplement, are not offered thereby. Forms of each
of the Agreements are filed as exhibits to the Registration Statement of which
this Prospectus is a part. The Agreement relating to each Series of Securities
will be filed as an exhibit to a report on Form 8-K to be filed with the
Commission within fifteen days after the initial issuance of such Securities and
a copy thereof will be available for inspection at the corporate trust office of
the Trustee specified in the related Prospectus Supplement (the "Corporate Trust
Office"). The following summaries describe certain provisions of the Agreements.
The summaries do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all of the provisions of the
Agreement for each Trust Fund and the related Prospectus Supplement.
 
GENERAL
 
     The Certificates of each Series (including any class of Certificates not
offered hereby) will be issued in fully registered form only and will represent
the entire beneficial ownership interest in the Trust Fund created pursuant to
the related Agreement. Unless otherwise specified in the related Prospectus
Supplement, each Series of Notes covered by a particular Indenture will evidence
indebtedness of a separate Trust Fund created pursuant to the related Owner
Trust Agreement. As to each Series, the Securities will be issued in authorized
denominations evidencing a portion of all of the Securities of such Series (a
"Percentage Interest"), as set forth in the related Prospectus Supplement. Each
Trust Fund will consist of (i) such Residential Loans (including any Mortgage
Securities) or Agency Securities (exclusive of any portion of interest payments
relating thereto retained by the Depositor, any of its affiliates or its
predecessor in interest (the "Retained Interest") and exclusive of principal and
interest due on or before the Cut-off Date) as from time to time are subject to
the Agreement; (ii) such funds or assets as from time to time are deposited in
the Trust Account described below and any other account held for the benefit of
Securityholders; (iii) with respect to Trust Funds that include Residential
Loans, (a) property acquired by foreclosure or deed in lieu of foreclosure of
Mortgage Loans on behalf of the Securityholders, or, in the case of Manufactured
Housing Contracts that are not Land Contracts, by repossession; (b) any Primary
Credit Insurance Policies and Primary Hazard Insurance Policies (as defined
under "Description of Primary Insurance Coverage"); (c) any combination of a
Pool Insurance Policy, a Bankruptcy Bond, a special hazard insurance policy or
other type of credit support (as defined under "Description of Credit Support");
and (d) the rights of the Trustee to any cash advance reserve fund or surety
bond as described under "Advances"; (iv) if specified in the related Prospectus
Supplement, the Reserve Fund and (v) any other assets as described in the
related Prospectus Supplement. The Securities will be transferable and
exchangeable for Securities of the same class and Series in authorized
denominations at the Corporate Trust Office. No service charge will be made for
any registration of exchange or transfer of Securities on the Certificate
Register maintained by the Certificate Registrar, but the Depositor may require
payment of a sum sufficient to cover any tax or other governmental charge.
 
     Each Series of Securities may consist of either (i) a single class of
Securities; (ii) two or more classes of Securities, one or more classes of which
("Senior Securities") will be senior in right of payment to one or more of the
other classes ("Subordinate Securities") to the extent described in the related
Prospectus Supplement (any such Series, a "Senior/Subordinate Series"); (iii)
two or more classes of Securities, one or more classes of which will be entitled
to (a) principal distributions, with disproportionate, nominal or no interest
distributions or (b) interest distributions, with disproportionate, nominal or
no principal distributions ("Strip Securities"); (iv) two or more classes of
Securities that differ as to the timing, sequential order or amount of
distributions of principal or interest or both, which may include one or more
classes of Securities ("Accrual Securities") with
 
                                       36
<PAGE>
respect to which accrued interest will not be distributed but rather will be
added to the Security Principal Balance thereof on each Distribution Date for
the period described in the related Prospectus Supplement; or (v) other types of
classes of Securities, as described in the related Prospectus Supplement. Credit
support for each Series of Securities evidencing interests in a Trust Fund that
includes Residential Loans will be provided by a Pool Insurance Policy, a
special hazard insurance policy, a Bankruptcy Bond, a letter of credit, a
Reserve Fund or a similar credit support instrument as described under
"Description of Credit Support," by the subordination of one or more classes of
Securities as described under "Description of the Securities--Subordination," or
by any combination of the foregoing.
 
     Each class of Securities (other than certain Strip Securities) will have a
Security Principal Balance and, unless otherwise provided in the related
Prospectus Supplement, will be entitled to payments of interest thereon based on
a specified Security Interest Rate. See "Principal and Interest on the
Securities" below. The Security Interest Rates of the various classes of
Securities of each Series may differ, and as to some classes may be in excess of
the lowest Net Interest Rate in a Trust Fund; however, the weighted average of
the Security Interest Rates on the Securities based on their respective Security
Principal Balances will not exceed the lowest Net Interest Rate. The specific
percentage ownership interests of each class of Securities and the minimum
denomination per Security will be set forth in the related Prospectus
Supplement. As to any Mortgage Loan, the "Net Interest Rate" is equal to the
Interest Rate minus the sum of the Administration Fee Rate and the rate at which
the Retained Interest, if any is calculated (the "Retained Interest Rate").
 
     If so provided in the related Prospectus Supplement relating to a Series of
Certificates, one or more elections may be made to treat the related Trust Fund,
or designated portions thereof, as a "real estate mortgage investment conduit"
(a "REMIC") as defined in the Code. If such an election is made with respect to
a Series, one of the classes will be designated as evidencing all "residual
interests" in the related REMIC as defined under the Code. All other classes of
Securities in such a Series will constitute "regular interests" in the related
REMIC as defined in the Code. As to each Series, all of the Securities of each
class offered hereby will be rated in one of the four highest rating categories
by one or more Rating Agencies. As to each Series of Certificates as to which a
REMIC election is to be made, the Trustee or the Master Servicer, if any, will
be obligated to take all actions required in order to comply with applicable
laws and regulations and, unless otherwise specified in the related Prospectus
Supplement, will be obligated to pay any prohibited transaction taxes or
contribution taxes arising out of a breach of its obligations with respect to
such compliance without any right of reimbursement therefor from the Trust Fund
or from any Certificateholder. Unless otherwise provided in the related
Prospectus Supplement, a prohibited transaction tax or contribution tax
resulting from any other cause will be charged against the related Trust Fund,
resulting in a reduction in amounts otherwise distributable to
Certificateholders. See "Certain Federal Income Tax Consequences--REMICs--Taxes
that may be Imposed on the REMIC Pool--Prohibited Transactions."
 
ASSIGNMENT OF TRUST FUND ASSETS
 
     At the time of issuance of each Series of Securities, the Depositor will
cause the assets comprising the related Trust Fund or Mortgage Securities being
included in the related Trust Fund to be assigned to the Trustee, together with
all principal and interest received by or on behalf of the Depositor with
respect to the Trust Fund Assets after the applicable Cut-off Date, other than
principal and interest due on or before the applicable Cut-off Date and other
than any Retained Interest. The Residential Loan or Agency Security documents
described below will be delivered to the Trustee (or to the custodian
hereinafter referred to). The Trustee will, concurrently with such assignment,
deliver the Securities to the Depositor in exchange for the Trust Fund Assets.
Each Trust Fund Asset will be identified in a schedule appearing as an exhibit
to the related Agreement. Such schedule will include, among other things,
information as to the outstanding principal balance of each Trust Fund Asset
after application of payments due on or before the Cut-off Date, the maturity of
the Mortgage Note, Cooperative Note, Manufactured Housing Contract or Agency
Securities, the Net Interest Rate, any Retained Interest, with respect to a
Series of Securities evidencing interests in a Trust Fund including Agency
Securities, the pass-through rate on the Agency Securities, and with respect to
a Series of Securities evidencing interests in Residential Loans, information
respecting the Interest Rate, the current scheduled payment of principal and
interest, the original Loan-to-Value Ratio and certain other information.
 
                                       37
<PAGE>
MORTGAGE LOANS AND MULTIFAMILY LOANS
 
     The Depositor will, as to each Mortgage Loan (other than Mortgage Loans
underlying any Mortgage Securities) and Multifamily Loan, deliver or cause to be
delivered to the Trustee (or to the custodian) the mortgage file for each
Mortgage Loan, containing legal documents relating to such Mortgage Loan,
including the Mortgage Note endorsed without recourse to the order of the
Trustee, the 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
certified by the related Unaffiliated Seller that it is a true and complete copy
of the original of such Mortgage submitted for recording) and an assignment in
recordable form of the Mortgage to the Trustee. Unless otherwise provided in the
related Prospectus Supplement, the Depositor will promptly cause the assignment
of each related Mortgage Loan and Multifamily Loan to be recorded in the
appropriate public office for real property records, except in states where, in
the opinion of counsel acceptable to the Trustee, such recording is not required
to protect the Trustee's interest in the Mortgage Loan or Multifamily Loan
against the claim of any subsequent transferee or any successor to or creditor
of the Depositor or the originator of such Mortgage Loan.
 
HOME EQUITY LOANS AND HOME IMPROVEMENT CONTRACTS
 
     Unless otherwise provided in the related Prospectus Supplement, the
Depositor will, as to each Home Equity Loan and Home Improvement Contract,
deliver or cause to be delivered to the Trustee (or to the custodian) the note
endorsed to the order of the Trustee, with respect to Home Equity Loans and
secured Home Improvement Contracts, the 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 certified by the related Unaffiliated Seller
that it is a true and complete copy of the original of such Mortgage submitted
for recording) and, with respect to Home Equity Loans and secured Home
Improvement Contracts, an assignment in recordable form of the Mortgage to the
Trustee. Unless otherwise provided in the related Prospectus Supplement, the
Depositor will promptly cause the assignment of each related Home Equity Loan
and secured Home Improvement Contract to be recorded in the appropriate public
office for real property records, except in states where, in the opinion of
counsel acceptable to the Trustee, such recording is not required to protect the
Trustee's interest in the Home Equity Loan and Home Improvement Contract against
the claim of any subsequent transferee or any successor to or creditor of the
Depositor or the originator of such Home Equity Loan or Home Improvement
Contract. With respect to unsecured Home Improvement Contracts, the Depositor or
Unaffiliated Seller, under the related Agreement, will transfer physical
possession of the Home Improvement Contracts to the Trustee or a designated
custodian or, in the case of an Unaffiliated Seller, may retain possession of
the Home Improvement Contracts as custodian for the Trustee. In addition, the
Depositor will cause to be made, an appropriate filing of a UCC-1 financing
statement in the appropriate states to give notice of the Trustee's ownership of
the Home Improvement Contracts. Unless otherwise specified in the related
Prospectus Supplement, the Home Improvement Contracts will not be stamped or
otherwise marked to reflect their assignment from the Unaffiliated Seller or the
Depositor, as the case may be, 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 Trustee's interest in
the contracts could be defeated.
 
COOPERATIVE LOANS
 
     The Depositor will, as to each Cooperative Loan, deliver or cause to be
delivered to the Trustee (or to the custodian) the related Cooperative Note, the
original security agreement, the proprietary lease or occupancy agreement, the
related stock certificate and related stock powers endorsed in blank, and a copy
of the original filed financing statement together with an assignment thereof to
the Trustee in a form sufficient for filing. The Depositor will promptly cause
the assignment and financing statement of each related Cooperative Loan to be
filed in the appropriate public office, except in states where in the opinion of
counsel acceptable to the Trustee, such filing is not required to protect the
Trustee's interest in the Cooperative Loan against the claim of any subsequent
transferee or any successor to or creditor of the Depositor or the originator of
such Cooperative Loan.
 
                                       38
<PAGE>
MANUFACTURED HOUSING CONTRACTS
 
     Unless otherwise provided in the related Prospectus Supplement, the
Depositor will, as to each Manufactured Housing Contract, deliver or cause to be
delivered to the Trustee (or to the custodian) the original Manufactured Housing
Contract endorsed to the order of the Trustee and copies of documents and
instruments related to each Manufactured Housing Contract and the security
interest in the Manufactured Home securing each Manufactured Housing Contract,
together with a blanket assignment to the Trustee of the Manufactured Housing
Contracts in the related Trust Fund and such documents and instruments. Unless
otherwise provided in the related Prospectus Supplement, in order to give notice
of the right, title and interest of the Securityholders to the Manufactured
Housing Contracts, the Depositor will cause to be executed and delivered to the
Trustee a UCC-1 financing statement identifying the Trustee as the secured party
and identifying all Manufactured Housing Contracts as collateral of the Trust
Fund.
 
AGENCY SECURITIES
 
     Agency Securities will be registered in the name of the Trustee or its
nominee on the books of the issuer or guarantor or its agent or, in the case of
Agency Securities issued only in book-entry form, through the Federal Reserve
System, in accordance with the procedures established by the issuer or guarantor
for registration of such certificates with a member of the Federal Reserve
System, and distributions on such securities to which the Trust Fund is entitled
will be made directly to the Trustee.
 
REVIEW OF RESIDENTIAL LOANS
 
     The Trustee (or the custodian) will review the Residential Loan documents
within 45 days (or such other period specified in the Prospectus Supplement)
after receipt thereof, and the Trustee (or such custodian) will hold such
documents in trust for the benefit of the 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)
shall immediately notify the Master Servicer and the Depositor, and the Master
Servicer shall immediately notify the applicable Unaffiliated Seller. If the
Unaffiliated Seller cannot cure the omission or defect within 90 days (or such
other period specified in the Prospectus Supplement) after receipt of such
notice, the Unaffiliated Seller will be obligated to repurchase the related
Residential Loan from the Trustee at the Purchase Price or, in certain cases,
substitute for such Residential Loan. There can be no assurance that an
Unaffiliated Seller will fulfill this repurchase or substitution obligation.
Although the Master Servicer or Trustee is obligated to enforce such obligation
to the extent described above under "Residential Loan Program--Representations
by Unaffiliated Sellers; Repurchases", neither the Master Servicer nor the
Depositor will be obligated to repurchase or substitute for such Residential
Loan if the Unaffiliated Seller defaults on its obligation. Unless otherwise
specified in the related Prospectus Supplement, this repurchase or substitution
obligation, if applicable, constitutes the sole remedy available to the
Securityholders or the Trustee for omission of, or a material defect in, a
constituent document.
 
     The Trustee will be authorized to appoint a custodian pursuant to a
custodial agreement to maintain possession of and review the documents relating
to the Residential Loans as agent of the Trustee.
 
     Unless otherwise provided in the related Prospectus Supplement, with
respect to Residential Loans, except as to Mortgage Loans underlying any
Mortgage Securities, in a Trust Fund, the Depositor will make representations
and warranties as to the types and geographical distribution of such Residential
Loans and as to the accuracy in all material respects of certain identifying
information furnished to the Trustee in respect of each such Residential Loan
(e.g., original Loan-to-Value Ratio, principal balance as of the Cut-off Date,
Interest Rate and maturity). In addition, unless otherwise provided in the
related Prospectus Supplement, the Depositor will represent and warrant that, as
of the Cut-off Date for the related Series of Securities, no Residential Loan
was currently more than 30 days delinquent as to payment of principal and
interest and no Residential Loan was 30 days or more delinquent more than once
during the previous 12 months. Upon a breach of any such representation of the
Depositor that materially and adversely affects the interests of the
Securityholders in a Residential Loan, the Depositor will be obligated either to
cure the breach in all material respects, repurchase the Residential Loan at the
Purchase Price or, if provided in the related Prospectus Supplement, substitute
for such Residential Loan.
 
                                       39
<PAGE>
     With respect to any Series of Securities evidencing interests in a Trust
Fund including Residential Loans as to which credit support is provided by means
of a pool insurance policy, in addition to making the representations and
warranties described above, the Depositor or the Unaffiliated Seller will, to
the extent required by the Rating Agency or Agencies, represent and warrant to
the Trustee for such Series of Securities that no action, inaction or event has
occurred and no state of facts exists or has existed on or prior to the date of
the initial issuance of the Securities that has resulted or will result in the
exclusion from, denial of or defense to coverage under any applicable primary
credit insurance policy, pool insurance policy, special hazard insurance policy
or bankruptcy bond, irrespective of the cause of such failure of coverage but
excluding any failure of an insurer to pay by reason of the insurer's own breach
of its insurance policy or its financial inability to pay (such representation
being referred to herein as the "insurability representation"). See "Description
of Primary Insurance Coverage" and "Description of Credit Support" herein and in
the related Prospectus Supplement for information regarding the extent of
coverage under the aforementioned insurance policies. As described in the
related Prospectus Supplement, upon a breach of the insurability representation
that materially and adversely affects the interests of the Securityholders in a
Residential Loan, the Depositor or the Unaffiliated Seller may be obligated
either to cure the breach in all material respects or to purchase such
Residential Loan at the Purchase Price, subject to the limitations specified in
the related Prospectus Supplement. The related Prospectus Supplement may provide
that the performance of the Depositor of its obligation to repurchase
Residential Loans following a breach of its insurability representation will be
ensured in the manner specified therein.
 
     The related Prospectus Supplement may provide that, the obligation to
repurchase or, other than with respect to the insurability representation, if
applicable, to substitute Residential Loans as described above constitutes the
sole remedy available to the Securityholders or the Trustee for any breach of
the Depositor's representations.
 
     The Master Servicer will make certain representations and warranties
regarding its authority to enter into, and its ability to perform its
obligations under, the related Pooling and Servicing Agreement. Upon the
occurrence of an Event of Default under the related Pooling and Servicing
Agreement for which the Master Servicer is responsible, the Master Servicer will
be obligated to remedy such Event of Default within the time period set forth in
the related Pooling and Servicing Agreement or be subject to termination
pursuant thereto. See "Description of the Securities--Events of Default" and
"--Rights Upon Event of Default" herein.
 
DEPOSITS TO THE TRUST ACCOUNT
 
     The Master Servicer or the Trustee shall, as to each Trust Fund, establish
and maintain or cause to be established and maintained a separate Trust Account
or Trust Accounts for the collection of payments on the related Trust Fund
Assets, which must either be (i) maintained with a federal or state chartered
depository institution, and in a manner, satisfactory to each Rating Agency
rating the Securities of such Series at the time any amounts are held on deposit
therein or (ii) maintained with a federal or state chartered depository
institution, the deposits in which are insured by the BIF or the SAIF (to the
limits established by the FDIC) and any uninsured deposits in which are
otherwise secured such that the Securityholders have a claim with respect to the
funds in the Trust 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 Trust Account is maintained. The collateral eligible to secure amounts in
the Trust Account is limited to United States government securities and other
high quality investments ("Permitted Instruments"). A Trust Account may be
maintained as an interest bearing or non-interest bearing account, or the funds
held therein may be invested pending the distribution on each succeeding
Distribution Date in Permitted Instruments. Unless otherwise provided in the
related Prospectus Supplement, the Trustee or the Master Servicer will be
entitled to receive any such interest or other income earned on funds in the
Trust Account as additional compensation for administration of the Trust Fund
Assets. In respect of any Series of Securities having Distribution Dates
occurring less frequently than monthly, the Master Servicer may obtain from an
obligor named in the related Prospectus Supplement a guaranteed investment
contract to assure a specified rate of return on funds held in the Trust
Account. If permitted by each Rating Agency rating the Securities of such
Series, a Trust Account may contain funds relating to more than one Series of
Securities.
 
                                       40
<PAGE>
     In the event that a Sub-Servicer is servicing one or more Residential Loans
in a Trust Fund, the Sub-Servicer will establish and maintain a separate account
or accounts (a "Sub-Servicing Account"), which may be interest bearing or
non-interest bearing and which shall comply with the standards for Trust
Accounts set forth above, and which is otherwise acceptable to the Master
Servicer. The Sub-Servicer is required to credit to the related Sub-Servicing
Account on a daily basis the amount of all proceeds of Residential Loans
received by the Sub-Servicer, less its servicing compensation, its Retained
Interest, if any, and unreimbursed expenses and advances to which it is entitled
pursuant to the related Sub-Servicing Agreement. As specified in the related
Prospectus Supplement, the Sub-Servicer shall remit to the Master Servicer all
funds held in the Sub-Servicing Account with respect to each Residential Loan
and any amount required to be advanced pursuant to the related Sub-Servicing
Agreement on a monthly basis.
 
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 the Pre-Funded Amount on the related Closing Date. 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 three months after the Closing Date. 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.
 
PAYMENTS ON RESIDENTIAL LOANS
 
     The Master Servicer will deposit or cause to be deposited in the Trust
Account for each Trust Fund including Residential Loans as and when received
(or, in the case of Advances on or before the applicable Distribution Date),
unless otherwise provided in the related Agreement, the following payments and
collections received or made by or on behalf of the Master Servicer subsequent
to the Cut-off Date (unless otherwise specified in the related Prospectus
Supplement, other than payments due on or before the Cut-off Date and exclusive
of any amounts representing a Retained Interest):
 
          (i) all payments on account of principal, including principal
     prepayments, on the Residential Loans;
 
          (ii) all payments on account of interest on the Residential Loans,
     exclusive of any portion thereof representing interest in excess of the Net
     Interest Rate (unless such excess amount is required to be deposited
     pursuant to the related Agreement) and, if provided in the related
     Prospectus Supplement, prepayment penalties;
 
          (iii) all proceeds of any Primary Hazard Insurance Policies and any
     special hazard insurance policy (to the extent such proceeds are not
     applied to the restoration of the property or released to the borrower in
     accordance with the Master Servicer's normal servicing procedures), any
     Primary Credit Insurance Policy, any FHA Insurance, VA Guarantee, any
     Bankruptcy Bond and any Pool Insurance Policy (as hereinafter defined)
     (collectively, "Insurance Proceeds"), other than proceeds that represent
     reimbursement of the Master Servicer's costs and expenses incurred in
     connection with presenting claims under the related insurance policies, and
     all other cash amounts received, by foreclosure, eminent domain,
     condemnation or otherwise, in connection with the liquidation of defaulted
     Residential Loans included in the related Trust Fund ("Liquidation
     Proceeds"), together with the net proceeds on a monthly basis with respect
     to any properties acquired for the benefit of Securityholders by deed in
     lieu of foreclosure or repossession;
 
          (iv) any Advances made as described below under "Advances";
 
          (v) all amounts required to be transferred to the Trust Account from a
     Reserve Fund, if any, as described below under "Subordination";
 
          (vi) all proceeds of any Residential Loan or property in respect
     thereof purchased by the Master Servicer, the Depositor, any Sub-Servicer
     or any Unaffiliated Seller as described under "Residential Loan Program--
     Representations by Unaffiliated Sellers; Repurchases" and "Description of
     the Certificates--
 
                                       41
<PAGE>
     Assignment of Trust Fund Assets" above, exclusive of the Retained Interest,
     if any, in respect of such Residential Loan, and all proceeds of any
     Residential Loan repurchased as described under "Termination" below;
 
          (vii) all payments required to be deposited in the Trust Account with
     respect to any deductible clause in any blanket insurance policy described
     under "Description of Primary Insurance Coverage--Primary Hazard Insurance
     Policies";
 
          (viii) any amount required to be deposited by the Trustee or the
     Master Servicer in connection with losses realized on investments of funds
     held in the Trust Account;
 
          (ix) any amounts required to be transferred to the Trust Account
     pursuant to any guaranteed investment contract;
 
          (x) any distributions received on any Mortgage Securities included in
     the related Trust Fund; and
 
          (xi) any other amount required to be deposited in the Trust Account
     pursuant to the Agreement.
 
PAYMENTS ON AGENCY SECURITIES
 
     The Agency Securities included in a Trust Fund will be registered in the
name of the Trustee so that all distributions thereon will be made directly to
the Trustee. The Trustee will deposit or cause to be deposited into the Trust
Account for each Trust Fund including Agency Securities as and when received,
unless otherwise provided in the related Trust Agreement, all distributions
received by the Trustee with respect to the related Agency Securities (other
than payments due on or before the Cut-off Date and exclusive of any trust
administration fee and amounts representing the Retained Interest, if any).
 
DISTRIBUTIONS
 
     Distributions of principal and interest on the Securities of each Series
will be made by or on behalf of the Trustee or the Master Servicer on the dates
(each, a "Distribution Date") and at the intervals (which may be monthly,
quarterly, semi-annual or other intervals) specified in the related Prospectus
Supplement, to the persons in whose names the Securities are registered at the
close of business on the record date ("Record Date") specified in the Prospectus
Supplement. The amount of each distribution will be determined as of the close
of business on each Determination Date specified in the related Prospectus
Supplement. Distributions will be made either by wire transfer in immediately
available funds to the account of a Securityholder at a bank or other entity
having appropriate facilities therefor, if such Securityholder has so notified
the Trustee or the Master Servicer and holds Securities in any requisite amount
specified in the related Prospectus Supplement, or by check mailed to the
address of the person entitled thereto as it appears on the Security Register;
provided, however, that the final distribution in retirement of the Securities
will be made only upon presentation and surrender of the Securities at the
office or agency of the Security Registrar specified in the notice to
Securityholders of such final distribution. Unless otherwise specified in the
Prospectus Supplement, all distributions made to the holders of Securities of
any Series on each Distribution Date will be made on a pro rata basis among the
Securityholders of record on the next preceding Record Date (other than in
respect of the final distribution), based on the aggregate Percentage Interest
represented by their respective Securities.
 
FINAL DISTRIBUTION DATE
 
     With respect to any Series consisting of classes having sequential
priorities for distributions of principal, the "Final Distribution Date" for
each such class of Securities is the latest Distribution Date on which the
Security Principal Balance thereof is expected to be reduced to zero, based on
certain assumptions, including the assumption that no prepayments or defaults
occur with respect to the related Trust Fund Assets, as further or as otherwise
specified in the related Prospectus Supplement. Since the rate of distribution
of principal of any such class of Securities will depend upon, among other
things, the rate of payment (including prepayments) of the principal of the
Trust Fund Assets, the actual last Distribution Date for any class of Securities
could occur significantly earlier than its Final Distribution Date. The rate of
payments on the Trust Fund Assets for any Series of Securities will depend upon
their particular characteristics, as well as on the prevailing level of interest
rates from time to time and other economic factors, and no assurance can be
given as to the actual prepayment
 
                                       42
<PAGE>
experience of the Trust Fund Assets. See "Maturity and Prepayment
Considerations." In addition, substantial losses on the Trust Fund Assets in a
given period, even though within the limits of the protection afforded by the
instruments described under "Description of Credit Support," or by the
Subordinate Securities in the case of a Senior/Subordinate Series, may cause the
actual last Distribution Date of certain classes of Securities to occur after
their Final Distribution Date.
 
SPECIAL DISTRIBUTIONS
 
     With respect to any Series of Securities with Distribution Dates occurring
at intervals less frequently than monthly, the Securities may be subject to
special distributions under the circumstances and in the manner described below
if and to the extent provided in the related Prospectus Supplement. If
applicable, the Master Servicer will be required to make or cause to be made
special distributions allocable to principal and interest on Securities of a
Series out of, and to the extent of, the amount available therefor in the
related Trust Account, on the day specified in the related Prospectus
Supplement, in the amount described below if, as a result of substantial
payments of principal on the Trust Fund Assets, low rates then available for
reinvestment of payments on such Trust Fund Assets, substantial Realized Losses
or some combination thereof, and based on the assumptions specified in the
related Agreement, it is determined that the amount anticipated to be on deposit
in the Trust Account on the next Distribution Date or on some intervening date
as provided in the related Prospectus Supplement, together with, if applicable,
the amount available to be withdrawn from any related Reserve Fund, may be
insufficient to make required distributions on the Securities of such Series on
such Distribution Date or such intervening date as may be provided in the
related Prospectus Supplement. The amount of any special distribution that is
allocable to principal will not exceed the amount that would otherwise be
distributed as principal on the next Distribution Date from amounts then on
deposit in the Trust Account. All special distributions will include interest at
the applicable Trust Interest Rate on the amount of the special distribution
allocable to principal to the date specified in the related Prospectus
Supplement.
 
     All special distributions of principal will be made in the same priority
and manner as distributions in respect of principal on the Securities on a
Distribution Date. Special distributions of principal with respect to Securities
of the same class will be made on a pro rata basis. Notice of any special
distributions will be given by the Master Servicer or Trustee prior to the
special distribution date.
 
PRINCIPAL AND INTEREST ON THE SECURITIES
 
     Each class of Securities (other than certain classes of Strip Securities)
may have a different Certificate Interest Rate, which may be a fixed, variable
or adjustable Security Interest Rate. The related Prospectus Supplement will
specify the Security Interest Rate for each class, or in the case of a variable
or adjustable Security Interest Rate, the method for determining the Security
Interest Rate. Unless otherwise specified in the related Prospectus Supplement,
interest on the Securities will be calculated on the basis of a 360-day year
consisting of twelve 30-day months.
 
     As to each Series of Securities, with respect to each Distribution Date,
interest accruing with respect to each Security (the "Accrued Security
Interest"), other than a Strip Security, will be equal to interest on the
outstanding Security Principal Balance thereof immediately prior to the
Distribution Date, at the applicable Security Interest Rate, for a period of
time corresponding to the intervals between the Distribution Dates for such
Series. As to each Strip Security, the Stripped Interest with respect to any
Distribution Date will equal the amount described in the related Prospectus
Supplement for the related period. Unless otherwise specified in the related
Prospectus Supplement, the Accrued Security Interest on each Security of a
Series will be reduced, in the event of shortfalls in collections of interest
resulting from prepayments of Residential Loans that are not covered by payments
by the Master Servicer out of its servicing fees or by application of prepayment
penalties, with such shortfall allocated among all of the Securities of that
Series in proportion to the respective amounts of Accrued Security Interest that
would have been payable thereon absent such reductions and absent any
delinquencies or losses. See "Yield Considerations" and "Maturity and Prepayment
Considerations." Unless otherwise provided in the related Prospectus Supplement,
neither the Trustee, the Master Servicer nor the Depositor will be obligated to
fund shortfalls in interest collections resulting from prepayments. Unless
otherwise specified in the related Prospectus Supplement, distributions of
Accrued Certificate Interest that would otherwise be payable on any class of
Accrual Securities of a Series will be added to the Security Principal Balance
thereof on each
 
                                       43
<PAGE>
Distribution Date until the Security Principal Balance of the Securities of all
other classes of such Series having a Final Distribution Date prior to the Final
Distribution Date of such class of Accrual Securities has been reduced to zero,
and actual payments of interest on the Accrual Securities will be made
thereafter. See "Final Distribution Date."
 
     Unless the related Prospectus Supplement provides otherwise, each Security
will have a "Security Principal Balance" that, at any time, will equal the
maximum amount that the holder will be entitled to receive in respect of
principal out of the future cash flow on the Trust Fund Assets and other assets
included in the related Trust Fund. With respect to each such Security,
distributions generally will be applied to accrued and currently payable
interest thereon, and thereafter to principal. The outstanding Security
Principal Balance of a Security will be reduced to the extent of distributions
in respect of principal thereon, and in the case of Securities evidencing
interests in a Trust Fund that includes Residential Loans, by the amount of any
Realized Losses, as defined below, allocated thereto.
 
     Unless the related Prospectus Supplement provides otherwise, the initial
aggregate Security Principal Balance of all classes of Securities of a Series
will equal the aggregate outstanding principal balance of the related Trust Fund
Assets as of the applicable Cut-off Date. The initial aggregate Security
Principal Balance of a Series and each class thereof will be specified in the
related Prospectus Supplement. Alternatively, the initial Security Principal
Balance for a Series of Securities may equal the initial aggregate "Cash Flow
Value" of the related Trust Fund Assets as the applicable Cut-off Date. The
aggregate Cash Flow Value of the Trust Fund Assets will be the Security
Principal Balance of the Certificates of such Series which, based on certain
assumptions (including the assumption that no defaults occur on the Trust Fund
Assets), can be supported by either the future scheduled payments on the Trust
Fund Assets (with the interest thereon adjusted to the Net Interest Rate), or
the proceeds of the prepayment of such Trust Fund Assets, together with
reinvestment earnings thereon, if any, at the applicable Assumed Reinvestment
Rate, and amounts available to be withdrawn from any Reserve Fund for such
Series, as further or as otherwise specified in the Prospectus Supplement
relating to a Series of Securities. The "Assumed Reinvestment Rate" for a Series
of Securities will be the highest rate permitted by the Rating Agency or
Agencies, or a rate insured pursuant to a guaranteed investment contract or
similar arrangement satisfactory to such Rating Agency or Agencies. If the
Assumed Reinvestment Rate is so insured, the Prospectus Supplement relating to a
Series of Securities will set forth the terms of such arrangement. The aggregate
of the initial Cash Flow Values of the Trust Fund Assets included in the Trust
Fund for a Series of Certificates will be at least equal to the aggregate
Security Principal Balance of the Securities of such Series at the date of
initial issuance thereof.
 
     With respect to any Series as to which the initial Security Principal
Balance is calculated on the basis of Cash Flow Values of the Trust Fund Assets,
the amount of principal distributed for such Series on each Distribution Date
will generally be calculated on the basis of (i) the decline in the aggregate
Cash Flow Values of the Trust Fund Assets during the related Due Period,
calculated in the manner prescribed in the related Agreement, minus (ii) with
respect to any Realized Loss incurred during the related Due Period and not
covered by any of the instruments described under "Description of Credit
Support," the portion of the Cash Flow Value of the Trust Fund Assets
corresponding to such Realized Loss; or as otherwise provided in the related
Prospectus Supplement as to any such Series which is a Senior/Subordinate
Series. Unless the related Prospectus Supplement provides otherwise, the "Due
Period" applicable to any Distribution Date will commence on the second day of
the month in which the immediately preceding Distribution Date occurs, or on the
day after the Cut-off Date in the case of the first Due Period, and will end on
the first day of the month of the related Distribution Date.
 
     Unless otherwise provided in the related Prospectus Supplement,
distributions in respect of principal will be made on each Distribution Date to
the class or classes of Security entitled thereto until the Security Principal
Balance of such class has been reduced to zero. In the case of a Series of
Securities that include two or more classes of Securities, the timing,
sequential order and amount of distributions (including distributions among
multiple classes of Senior Securities or Subordinate Securities) in respect of
principal on each such class shall be as provided in the related Prospectus
Supplement. Distributions in respect of principal of any class of Securities
will be made on a pro rata basis among all of the Securities of such class.
 
                                       44
<PAGE>
AVAILABLE DISTRIBUTION AMOUNT
 
     Unless otherwise specified in the related Prospectus Supplement, all
distributions on the Certificates of each Series on each Distribution Date will
be made from the following amounts (collectively, the "Available Distribution
Amount"):
 
          (i) the total amount of all cash on deposit in the related Trust
     Account as of the corresponding Determination Date exclusive of:
 
             (a) all monthly payments collected but due during a Due Period
        subsequent to the applicable Due Period;
 
             (b) all prepayments and any related prepayment penalties, and other
        unscheduled recoveries of principal and related payments of interest
        thereon, received subsequent to the related Prepayment Period; and
 
             (c) all other amounts in the Trust Account which are payable or
        reimbursable to the Depositor, the Master Servicer or the Trustee with
        respect to such Distribution Date;
 
          (ii) if so provided in the related Prospectus Supplement, any Advances
     made with respect to such Distribution Date;
 
          (iii) if so provided in the related Prospectus Supplement, any
     payments in respect of interest shortfalls resulting from principal
     prepayments;
 
          (iv) if so provided in the related Prospectus Supplement, all net
     income received in connection with the operation of any Residential
     Property acquired on behalf of the Securityholders through deed in lieu of
     foreclosure or repossession; and
 
          (v) if the related Prospectus Supplement so provides, interest or
     reinvestment income on amounts on deposit in the Trust Account (which may
     include income provided under a guaranteed investment contract).
 
     On each Distribution Date for a Series of Securities, the Trustee or the
Master Servicer will withdraw or cause to be withdrawn from the Trust Account
the entire Available Distribution Amount and distribute the same or cause the
same to be distributed to the related Securityholders in the manner set forth
herein and in the Prospectus Supplement.
 
SUBORDINATION
 
     A Senior/Subordinate Series will consist of one or more classes of Senior
Securities and one or more classes of Subordinate Securities, as specified in
the related Prospectus Supplement. Unless otherwise specified in the related
Prospectus Supplement, only the Senior Securities will be offered hereby.
Subordination of the Subordinate Securities of any Series will be effected by
either of the two following methods, or by any other alternative method as may
be described in the related Prospectus Supplement.
 
SHIFTING INTEREST SUBORDINATION
 
     With respect to any Series of Certificates as to which credit support is
provided by shifting interest subordination, in the event of any Realized Losses
on Residential Loans not in excess of the limitations described below, the
rights of the Subordinate Certificateholders to receive distributions with
respect to the Residential Loans will be subordinate to the rights of the Senior
Certificateholders. With respect to any defaulted Residential Loan that is
finally liquidated, through foreclosure sale, disposition of the related
Residential Property if acquired on behalf of the Certificateholders by deed in
lieu of foreclosure, repossession, or otherwise, the amount of loss realized, if
any (a "Realized Loss"), will equal the portion of the unpaid principal balance
remaining after application of all principal amounts recovered (net of amounts
reimbursable to the Master Servicer for related expenses). With respect to
certain Residential Loans the principal balances of which have been reduced in
connection with bankruptcy proceedings, the amount of such reduction will be
treated as a Realized Loss.
 
     All Realized Losses will be allocated to the Subordinate Certificates of
the related Series, until the Security Principal Balance of the Subordinate
Certificates thereof has been reduced to zero. Any additional Realized Losses
will be allocated to the Senior Certificates (or, if such Series includes more
than one class of Senior Certificates, either on a pro rata basis among all of
the Senior Certificates in proportion to their respective outstanding
Certificate Principal Balances or as otherwise provided in the related
Prospectus Supplement). With
 
                                       45
<PAGE>
respect to certain Realized Losses resulting from physical damage to Residential
Properties which are generally of the same type as are covered under a special
hazard insurance policy ("Special Hazard Losses"), the amount thereof that may
be allocated to the Subordinate Certificates of the related Series may be
limited to an amount (the "Special Hazard Subordination Amount") specified in
the related Prospectus Supplement. See "Description of Credit Support--Special
Hazard Insurance Policies." If so, any Special Hazard Losses in excess of the
Special Hazard Subordination Amount will be allocated among all outstanding
classes of Certificates of the related Series, either on a pro rata basis in
proportion to their outstanding Certificate Principal Balances, regardless of
whether any Subordinate Certificates remain outstanding, or as otherwise
provided in the related Prospectus Supplement.
 
     Any allocation of a Realized Loss to a Certificate will be made by reducing
the Security Principal Balance thereof as of the Distribution Date following the
Prepayment Period in which such Realized Loss was incurred. If so provided in
the related Prospectus Supplement, in the event of a Realized Loss, the Senior
Certificateholders may be entitled to receive a distribution in respect of
principal, to be paid from and to the extent of funds otherwise distributable to
the Subordinate Certificateholders, equal to the amount, if any, by which (i)
the then applicable Senior Percentage (as defined below) times the Scheduled
Principal Balance (as defined below) of the related Residential Loan exceeds
(ii) the total amount of the related unscheduled recovery which is allocable to
principal (the "Unrecovered Senior Portion"). Payments to the Senior
Certificateholders in respect of any Unrecovered Senior Portion on any
Distribution Date will only be made with respect to Realized Losses incurred in
connection with Residential Loans that were finally liquidated during the
preceding Prepayment Period and will not be made as to any Special Hazard Losses
in excess of the Special Hazard Subordination Amount, if applicable. As with any
other distribution in respect of principal, any payment to the holders of Senior
Certificates attributable to an Unrecovered Senior Portion will be applied to
reduce the Security Principal Balance thereof. At any given time, the percentage
corresponding to the ratio of the Security Principal Balance of the Senior
Certificates to the Security Principal Balances of all of the Certificates is
the "Senior Percentage," determined in the manner set forth in the related
Prospectus Supplement. As specified in the related Prospectus Supplement, the
"Scheduled Principal Balance" of any Residential Loan as of any date of
determination is equal to the unpaid principal balance thereof as of the date of
determination, reduced by the principal portion of all monthly payments due but
unpaid as of the date of determination.
 
     As set forth above, the rights of holders of the various classes of
Certificates of any Series to receive distributions of principal and interest is
determined by the aggregate Security Principal Balance of each such class. The
Security Principal Balance of any Certificate will be reduced by all amounts
previously distributed on such Certificate in respect of principal, and by any
Realized Losses allocated thereto. However, to the extent so provided in the
related Prospectus Supplement, holders of Senior Certificates may be entitled to
receive a disproportionately larger amount of prepayments received in certain
circumstances, which will have the effect (in the absence of offsetting losses)
of accelerating the amortization of the Senior Certificates and increasing the
respective percentage ownership interest evidenced by the Subordinate
Certificates in the related Trust Fund (with a corresponding decrease in the
Senior Percentage), as well as preserving the availability of the subordination
provided by the Subordinate Certificates. In addition, as set forth above,
Realized Losses will be first allocated to Subordinate Certificates by reduction
of the Security Principal Balance thereof, which will have the effect of
increasing the respective ownership interest evidenced by the Senior
Certificates in the related Trust Fund. If there were no Realized Losses or
prepayments of principal on any of the Residential Loans, the respective rights
of the holders of Certificates of any Series to future distributions would not
change.
 
CASH FLOW SUBORDINATION
 
     With respect to any Series of Securities as to which credit support is
provided by cash flow subordination, in the event of losses on the Residential
Loans not in excess of the Available Subordination Amount, the rights of the
Subordinate Securityholders to receive distributions of principal and interest
with respect to the Residential Loans will be subordinate to the rights of the
Senior Securityholders. The "Available Subordination Amount" at any time is
equal to the difference between the then applicable Maximum Subordination Amount
and the "Cumulative Subordination Payments" at such time. At the time of any
determination, Cumulative Subordination Payments equal the aggregate of amounts
paid to the Senior Securityholders that, but for the subordination provisions,
would otherwise have been payable to the Subordinate Securityholders. The
Available Subordination Amount will decrease whenever amounts otherwise payable
to the Subordinate Securityholders are
 
                                       46
<PAGE>
paid to the Senior Securityholders (including amounts withdrawn from the Reserve
Fund and paid to the Senior Securityholders), and will increase whenever there
is distributed to the Subordinate Securityholders amounts in respect of which
subordination payments have previously been paid to the Senior Securityholders
(which will occur only when subordination payments in respect of delinquencies
and certain other deficiencies have been recovered). The "Maximum Subordination
Amount" initially will equal a fixed percentage amount specified in the related
Prospectus Supplement of the aggregate initial principal balance of the
Residential Loans in the related Trust Fund, and will periodically be adjusted
in accordance with a formula specified in the Prospectus Supplement.
 
     The protection afforded to the Senior Securityholders from the
subordination provisions described herein will be effected both by the
preferential right of the Senior Securityholders to receive current
distributions from the Trust Fund (subject to the limitations described herein)
and by the establishment and maintenance of a cash reserve fund (the "Reserve
Fund"). The Reserve Fund may be funded by an initial cash deposit on the date of
the initial issuance of the related Series of Securities (the "Initial Deposit")
and by deposits of amounts otherwise due on the Subordinate Securities to the
extent set forth in the related Prospectus Supplement.
 
     Amounts in the Reserve Fund (other than earnings thereon) will be withdrawn
for distribution to Senior Securityholders as may be necessary to make full
distributions to such holders on a particular Distribution Date, as described
above. If on any Distribution Date, after giving effect to the distributions to
the Senior Securityholders on such date, the amount of the Reserve Fund exceeds
the amount required to be held therein (the "Specified Reserve Fund Balance"),
such excess will be withdrawn and distributed in the manner specified in the
related Prospectus Supplement.
 
     In the event the Reserve Fund is depleted before the Available
Subordination Amount is reduced to zero, the Senior Securityholders will
nevertheless have a preferential right to receive current distributions from the
Trust Fund to the extent of the then Available Subordination Amount. However,
under these circumstances, should current distributions be insufficient, the
Senior Securityholders could suffer shortfalls of amounts due to them. The
Senior Securityholders will bear their proportionate share of any losses
realized on the Trust Fund in excess of the Available Subordination Amount.
 
     Amounts remaining in the Reserve Fund after the Available Subordination
Amount is reduced to zero will no longer be subject to any claims or rights of
the Senior Securityholders of such Series.
 
     Funds in the Reserve Fund may be invested as provided in the related
Agreement in Permitted Instruments that mature according to a schedule set forth
in the related Agreement. The earnings or losses on such investments will be
applied in the manner described in the related Prospectus Supplement.
 
     The time necessary for the Reserve Fund to reach the Specified Reserve Fund
Balance will be affected by the prepayment, foreclosure, and delinquency
experience of the Residential Loans and therefore cannot accurately be
predicted.
 
SUBORDINATION AND CASH FLOW VALUES
 
     In the event that the Security Principal Balances of the various classes of
Securities comprising a Senior/Subordinate Series are based upon the Cash Flow
Value of the Residential Loans, a shortfall in amounts distributable to Senior
Securityholders on any Distribution Date will occur to the extent that the
Senior Percentage of the decline in the Cash Flow Value of the Residential Loans
during the related Deposit Period exceeds all collections and, if so provided in
the related Prospectus Supplement, Advances in respect of the Residential Loans,
minus Accrued Security Interest on the Security Principal Balances of the Senior
Securities for such Distribution Date. The loss attributable to any liquidated
Residential Loan shall be equal to the excess, if any, of the Cash Flow Value of
such Residential Loan over all net proceeds recovered and allocable to
principal. The "Deposit Period" with respect to any Distribution Date is the
period commencing on the day following the Determination Date immediately
preceding the related Determination Date and ending on the related Determination
Date.
 
     Because the Cash Flow Value of a Residential Loan will never exceed the
outstanding principal balance thereof, prepayments in full and liquidations of
the Residential Loans may result in proceeds attributable to principal in excess
of the corresponding Cash Flow Value decline. Any excess will be applied to
offset losses realized during the related Deposit Period (as such losses are
described in the immediately preceding paragraph)
 
                                       47
<PAGE>
in respect of other liquidated Residential Loans without affecting the remaining
subordination, and such excess may, if so provided in the related Prospectus
Supplement, be deposited in a Reserve Fund for future distributions.
 
ADVANCES
 
     With respect to any Series of Securities evidencing interests in a Trust
Fund that includes Residential Loans, other than a Senior/Subordinate Series,
unless otherwise provided in the related Prospectus Supplement, the Master
Servicer will be obligated to advance on or before each Distribution Date, from
its own funds, or from amounts held for future distribution in the Trust Account
that are not included in the Available Distribution Amount for such Distribution
Date (any such advance, an "Advance"), in an amount equal to the aggregate of
payments of principal and interest (adjusted to the applicable Net Interest
Rate) that were due during the related Due Period and that were delinquent (and
not advanced by any Sub-Servicer) on the Determination Date. Any amounts held
for future distribution and so used shall be replaced by the Master Servicer on
or before any future Distribution Date to the extent that funds in the Trust
Account on such Distribution Date shall be less than payments to Securityholders
required to be made on such date. Unless otherwise specified in a Prospectus
Supplement relating to a Series of Securities, the obligation of the Master
Servicer to make Advances will be subject to the good faith determination of the
Master Servicer that such advances will be reimbursable from related late
collections, Insurance Proceeds or Liquidation Proceeds. See "Description of
Credit Support." As specified in the related Prospectus Supplement with respect
to any Series of Securities as to which the Trust Fund includes Mortgage
Securities, the Master Servicer's advancing obligations, if any, will be
pursuant to the terms of such Mortgage Securities, as may be supplemented by the
terms of the applicable Pooling and Servicing Agreement.
 
     With respect to a Senior/Subordinate Series in which subordination is
effected through the "shifting interest" method, previously described herein,
unless otherwise provided in the related Prospectus Supplement, the Master
Servicer will make an Advance on each Distribution Date from its own funds or
from funds held in the Trust Account that are not included in the Available
Distribution Amount for such Distribution Date, in an aggregate amount equal to
the lesser of (a) the total of all amounts required to be distributed on each
class of Senior Securities on such Distribution Date that remain after applying
towards such payment the entire Available Distribution Amount, including funds
otherwise payable to the Subordinate Securityholders, and (b) the aggregate of
payments of principal and interest (adjusted to the applicable Net Interest
Rate) that were due during the related Due Period but were delinquent on the
related Determination Date and were not advanced by any Sub-Servicer. With
respect to a Senior/Subordinated Series in which subordination is effected
through the "cash flow" method previously described herein, unless otherwise
provided in the related Prospectus Supplement, the Master Servicer may be
obligated to make Advances in the manner provided in the preceding paragraph. In
either case, so long as the Security Principal Balance of the Subordinate
Securities in the case of subordination effected through the "shifting interest"
method, or the Available Subordination Amount in the case of subordination
effected through the "cash flow" method, has not been reduced to zero, the
Master Servicer will be obligated to make such Advances regardless of
recoverability from the related Residential Loans. Thereafter, such Advances are
required to be made only to the extent they are deemed by the Master Servicer to
be recoverable from related late collections, Insurance Proceeds, Liquidation
Proceeds, or otherwise, unless otherwise specified in the related Prospectus
Supplement. See "Description of Primary Insurance Coverage" and "Description of
Credit Support."
 
     If Distribution Dates for any Series of Securities occur less frequently
than each month, Advances shall be made on the intervening dates specified in
the related Prospectus Supplement.
 
     Advances are intended to maintain a regular flow of scheduled interest and
principal payments to Securityholders, rather than to guarantee or insure
against losses. Unless otherwise specified in a Prospectus Supplement relating
to a Series of Securities, Advances will be reimbursable to the Master Servicer,
without interest, out of related recoveries on the Residential Loans respecting
which such amounts were advanced, or, to the extent that the Master Servicer
shall determine that any such Advance previously made will not be ultimately
recoverable from Insurance Proceeds or Liquidation Proceeds (a "Nonrecoverable
Advance"), from any cash available in the Trust Account. If so specified in the
related Prospectus Supplement, the obligations of the Master Servicer to make
Advances may be secured by a cash advance reserve fund or a surety bond.
Information regarding the characteristics of, and the identity of any obligor
of, any such surety bond, will be set forth in the related Prospectus
Supplement.
 
                                       48

STATEMENTS TO SECURITYHOLDERS
 
     Unless otherwise provided in the related Prospectus Supplement, on each
Distribution Date, the Master Servicer or the Trustee will forward or cause to
be forwarded to each Securityholder of the related Series and to the Depositor a
statement including the following information (in the case of information
furnished pursuant to (i), (ii) and (iii) below, the amounts shall be expressed
as a dollar amount per minimum denomination Security):
 
          (i) the amount of such distribution, if any, allocable to principal,

          (vii) with respect to any Residential Property acquired through
     foreclosure, deed in lieu of foreclosure or repossession during the
     preceding calendar month, the loan number and principal balance of the
     related Residential Loan as of the close of business on the Distribution
     Date in such month and the date of acquisition thereof;
 
          (viii) the book value of any Residential Property acquired through
     foreclosure, deed in lieu of foreclosure or repossession as of the close of
     business on the last business day of the calendar month preceding the
     Distribution Date;
 
          (ix) the aggregate Scheduled Principal Balance and Stated Principal

     the Security Interest Rate applicable to such Distribution Date, as
     calculated in accordance with the method specified in the Prospectus

     Rate, for statements to be distributed in any month in which an adjustment
     date occurs, the adjusted Certificate Interest Rate applicable to the next
     succeeding Distribution Date;
 
          (xii) as to any Series including one or more classes of Accrual
     Securities, the interest accrued on each such class with respect to such
     Distribution Date and added to the Security Principal Balance thereof;
 
          (xiii) the amount deposited in the Reserve Fund, if any, on such
     Distribution Date;
 
          (xiv) the amount remaining in the Reserve Fund, if any, as of the
     close of business on such Distribution Date, after giving effect to
     distributions made on such Distribution Date;
 
          (xv) as to any Series that includes credit support, the amount of
     remaining coverage of each Insurance Instrument (as defined under
     "Collection and Other Servicing Procedures") included therein as of the
     close of business on such Distribution Date, or, in the case of a
     Senior/Subordinate Series, information as to the remaining amount of
     protection against losses afforded to the Senior Securityholders by the
     subordination provisions and information regarding any shortfalls in
     payments to the Senior Certificateholder which remain outstanding; and
 
                                       49
<PAGE>
          (xvi) with respect to any Series of Securities as to which the Trust
     Fund includes Mortgage Securities, certain additional information as
     required under the related Pooling and Servicing Agreement or Trust
     Agreement, as applicable.
 
     Within a reasonable period of time after the end of each calendar year, the
Master Servicer or the Trustee will furnish or cause to be furnished a report to
every person who was a holder of record of a Security at any time during such
calendar year setting forth the aggregate of amounts reported pursuant to (i),
(ii) and (iii) above for such calendar year or in the event such person was a
holder of record during a portion of such calendar year, for the applicable
portion of such year.
 
     The related Prospectus Supplement may provide that additional information
with respect to a Series of Securities will be included in such statements. In
addition, the Master Servicer or the Trustee shall file with the Internal
Revenue Service and furnish to holders of Securities such statements or
information as may be required by the Code or applicable procedures of the
Internal Revenue Service.
 
BOOK-ENTRY REGISTRATION OF SECURITIES
 
     As described in the Prospectus Supplement, if not issued in fully
registered form, each class of Certificates 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
Cedelbank, socete anonyme ("Cedel") or Euroclear (in Europe) if they are
participants ("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 Brussels, Belgium branch of Morgan Guarantee Trust Company of
New York ("Morgan") will act as depositary for Euroclear (in such capacities,
individually the "Relevant Depositary" and collectively the "European
Depositaries"). Except as described below, no Security 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 Security 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 Security
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 Security Owner's
Financial Intermediary is not a 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 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
Certificates, which
 
                                       50
<PAGE>
account is maintained with their respective Participants. Under the Rules and in
accordance with DTC's normal procedures, transfers of ownership of Certificates
will be executed through DTC and the accounts of the respective Participants at
DTC will be debited and credited. Similarly, the Participants and indirect
participants will make debits or credits, as the case may be, on their records
on behalf of the selling and purchasing 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 Certificates
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 Certificates 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 the Rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons 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
the 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 to
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, under contract with Euroclear Clearance Systems S.C., a Belgium
cooperative corporation (the "Euroclear 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
Euroclear Cooperative. The Euroclear 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.
 
                                       51

     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. 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 the relevant United States tax laws and regulations. See "Certain Federal
Income Tax Consequences" 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, or otherwise take actions in respect of such Book-Entry Securities, may
by 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.
 
     Unless otherwise specified in the related Prospectus Supplement, monthly
and annual reports on the Trust Fund 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.
 
     It is the Depositor's understanding 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 Certificates 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 applicable
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
reregistration, 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 Certificates held by
Cede & Co., as nominee for DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

COLLECTION AND OTHER SERVICING PROCEDURES
 
RESIDENTIAL LOANS
 
     The Master Servicer, directly or through Sub-Servicers, will make
reasonable efforts to collect all required payments under the Residential Loans
and will follow or cause to be followed such collection procedures as it would
follow with respect to the servicing of residential loans that are comparable to
the Residential Loans and held for its own account, provided such procedures are
consistent with the related Agreement and any insurance policy, bond or other
instrument described under "Description of Primary Insurance Coverage" or
"Description of Credit Support" (any such instrument providing, or insofar as it
provides, coverage as to losses resulting from physical damage, a "Hazard
Insurance Instrument," any such instrument providing, or insofar as it provides,
coverage as to credit or other risks, a "Credit Insurance Instrument," and
collectively, an "Insurance Instrument"). With respect to any Series of
Securities as to which the Trust Fund includes Mortgage Securities, the Master
Servicer's servicing and administration obligations, if any, will be pursuant to
the terms of such Mortgage Securities.
 
     In any case in which a Residential Property has been, or is about to be,
conveyed, or in the case of a multifamily Residential Property, encumbered, by
the borrower, the Master Servicer will, to the extent it has knowledge of such
conveyance, encumbrance, or proposed conveyance or encumbrance, exercise or
cause to be exercised its rights to accelerate the maturity of such Residential
Loan under any due-on-sale or due-on-encumbrance 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 related Insurance
Instrument. If these conditions are not met or if the Master Servicer or
Sub-Servicer reasonably believes it is unable under applicable law to enforce
such due-on-sale or due-on-encumbrance clause, the Master Servicer or
Sub-Servicer will enter into or cause to be entered into an assumption and
modification agreement with the person to whom such property has been conveyed,
encumbered or is proposed to be conveyed or encumbered, pursuant to which such
person becomes liable under the Mortgage Note, Cooperative Note, Home
Improvement Contract or Manufactured Housing Contract and, to the extent
permitted by applicable law, the borrower remains liable thereon and provided
that coverage under any Insurance Instrument with respect to such Residential
Loan is not adversely affected. The Master Servicer is also authorized to enter
into a substitution of liability agreement with such person, pursuant to which
the original borrower is released from liability and such person is substituted
as the borrower and becomes liable under the Mortgage Note, Cooperative Note or
Contract. In connection with any such assumption, the Interest Rate, the amount
of the monthly payment or any other term affecting the amount or timing of
payment on the Residential Loan may not be changed. 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 compensation for
administering of the Trust Fund Assets. See "Certain Legal Aspects of
Residential Loans--Enforceability of Certain Provisions" and "--Prepayment
Charges and Prepayments." The Master Servicer shall notify the Trustee and any
custodian that any such assumption or substitution agreement has been completed.
 
AGENCY SECURITIES
 
     The Trust Agreement will require the Trustee, if it has not received a
distribution with respect to any Agency Security by the fifth business day after
the date on which such distribution was due and payable pursuant to the terms of
such Agency Security, to request the issuer or guarantor, if any, of such Agency
Security to make such payment as promptly as possible and legally permitted and
to take such legal action against such issuer or guarantor as the Trustee deems
appropriate under the circumstances, including the prosecution of any claims in
connection therewith. The reasonable legal fees and expenses incurred by the
Trustee in connection with the prosecution of any such legal action will be
reimbursable to the Trustee out of the proceeds of any such action and will be
retained by the Trustee prior to the deposit of any remaining proceeds in the
Trust Account pending distribution thereof to Securityholders of the related
Series. In the event that the proceeds of any such legal action may be
insufficient to reimburse the Trustee for its legal fees and expenses, the
Trustee will be entitled to withdraw from the Trust Account 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.
 
                                       53
<PAGE>
REALIZATION UPON DEFAULTED RESIDENTIAL LOANS
 
     As servicer of the Residential Loans, the Master Servicer, on behalf of
itself, the Trustee and the Securityholders, will present claims to the insurer
under each Insurance Instrument, to the extent specified in the related
Prospectus Supplement, and will take such reasonable steps as are necessary to
receive payment or to permit recovery thereunder with respect to defaulted
Residential Loans. As set forth above, all collections by or on behalf of the
Master Servicer under any Insurance Instrument, other than amounts to be applied
to the restoration of a Residential Property or released to the borrower, are to
be deposited in the Trust Account for the related Trust Fund, subject to
withdrawal as heretofore described. Unless otherwise provided in the Prospectus
Supplement relating to a Series of Securities, the Master Servicer will not
receive payment under any letter of credit included as an Insurance Instrument
with respect to a defaulted Residential Loan unless all Liquidation Proceeds and
Insurance Proceeds which it deems to be finally recoverable have been realized;
however, the Master Servicer will be entitled to reimbursement for any
unreimbursed advances and reimbursable expenses thereunder.
 
     If any property securing a defaulted Residential Loan is damaged and
proceeds, if any, from the related Hazard Insurance Instrument are insufficient
to restore the damaged property to a condition sufficient to permit recovery
under the related Credit Insurance Instrument, if any, 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 Residential 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 Residential Loan under any related Credit
Insurance Instrument is not available for the reasons set forth in the preceding
paragraph, or for any other reason, the Master Servicer nevertheless will be
obligated to follow or cause to be followed such normal practices and procedures
as it deems necessary, and appropriate for the type of defaulted Residential
Loan, or advisable to realize upon the defaulted Residential Loan. If the
proceeds of any liquidation of the property securing the defaulted Residential
Loan are less than the outstanding principal balance of the defaulted
Residential Loan (or the Cash Flow Value of such Mortgage Loan in the event that
Security Principal Balances are based upon Cash Flow Values), the amount of any
liens senior thereto plus interest accrued thereon at the Net Interest Rate
plus, the aggregate amount of expenses incurred by the Master Servicer in
connection with such proceedings and which are reimbursable under the related
Agreement, the Trust Fund will realize a loss in the amount of such difference.
If the Master Servicer recovers Insurance Proceeds which, when added to any
related Liquidation Proceeds and after deduction of certain expenses
reimbursable to the Master Servicer, exceed the outstanding principal balance of
the defaulted Residential Loan together with accrued interest at the Net
Interest Rate, the Master Servicer will be entitled to withdraw or cause to be
withdrawn from the Trust Account amounts representing its normal administration
compensation on such Residential Loan. In the event that the Master Servicer has
expended its own funds to restore damaged property and such funds have not been
reimbursed under any Insurance Instrument, it will be entitled to withdraw from
the Trust 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. Because 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 Residential Loan together with
accrued interest thereon at the Net Interest Rate. In addition, when property
securing a defaulted Residential Loan can be resold for an amount exceeding the
outstanding principal balance of the related Residential Loan together with
accrued interest and expenses, it may be expected that, if retention of any such
amount is legally permissible, the insurer will exercise its right under any
related pool insurance policy to purchase such property and realize for itself
any excess proceeds. See "Description of Primary Insurance Coverage" and
"Description of Credit Support."
 
     With respect to collateral securing a Cooperative Loan, any prospective
purchaser will generally have to obtain the approval of the board of directors
of the relevant Cooperative before purchasing the shares and acquiring rights
under the proprietary lease or occupancy agreement securing that Cooperative
Loan. See "Certain Legal Aspects of Residential Loans--Foreclosure on
Cooperatives." This approval is usually based on the purchaser's income and net
worth and numerous other factors. The necessity of acquiring such approval could
 
                                       54
<PAGE>
limit the number of potential purchasers for those shares and otherwise limit
the Master Servicer's ability to sell, and realize the value of, those shares.
 
RETAINED INTEREST, ADMINISTRATION COMPENSATION AND PAYMENT OF EXPENSES
 
     The Prospectus Supplement for a Series of Securities will specify whether
there will be any Retained Interest in any of the Trust Fund Assets. If so, the
Retained Interest will be established on a loan-by-loan or security-by-security
basis and will be specified in the related Agreement or in an exhibit to the
related Agreement. A Retained Interest in a Trust Fund Asset represents a
specified portion of the interest payable thereon. The Retained Interest will be
deducted from related payments as received and will not be part of the related
Trust Fund. Unless otherwise provided in the related Prospectus Supplement, any
partial recovery of interest on a Residential Loan, after deduction of all
applicable administration fees, will be allocated between Retained Interest, if
any, and interest at the Net Interest Rate on a pro rata basis.
 
     Unless otherwise specified in the related Prospectus Supplement, the
primary administration compensation of the Master Servicer (or in the case of a
Trust Fund consisting of Agency Securities, the Trustee) with respect to a
Series of Securities will come from the monthly payment to it, with respect to
each interest payment on a Trust Fund Asset, at a rate equal to one-twelfth of
the difference between the Interest Rate and the sum of the Net Interest Rate
and the Retained Interest Rate, if any (the "Administration Fee Rate"), times
the scheduled principal balance of such Trust Fund Asset. Notwithstanding the
foregoing, with respect to a Series of Securities as to which the Trust Fund
includes Mortgage Securities, the compensation payable to the Master Servicer or
Manager for servicing and administering such Mortgage Securities on behalf of
the holders of such Securities may be based on a percentage per annum described
in the related Prospectus Supplement of the outstanding balance of such Mortgage
Securities and may be retained from distributions thereon, if so specified in
the related Prospectus Supplement. Any Sub-Servicer will receive a portion of
the Master Servicer's primary compensation as its sub-servicing compensation.
Since any Retained Interest and the primary compensation of the Master Servicer
(or the Trustee) are percentages of the outstanding principal balance of each
Trust Fund Asset, such amounts will decrease as the Trust Fund Assets amortize.
 
     As additional compensation in connection with a Series of Securities
relating to Residential Loans, the Master Servicer or the Sub-Servicers, if any,
will retain all assumption fees and late payment charges, if any, to the extent
collected from borrowers, and, if so provided in the related Prospectus
Supplement, any prepayment fees collected from the borrowers and any excess
recoveries realized upon liquidation of a defaulted Residential Loan. Unless
otherwise provided in the related Prospectus Supplement, any interest or other
income that may be earned on funds held in the Trust Account pending monthly,
quarterly, semiannual or other periodic distributions, as applicable, or any
Sub-Servicing Account may be paid as additional compensation to the Trustee, the
Master Servicer or the Sub-Servicers, as the case may be.
 
     With respect to a Series of Securities relating to Residential Loans, the
Master Servicer will pay from its administration compensation certain expenses
incurred in connection with its servicing of the Residential Loans, including,
without limitation, amounts payable to any Sub-Servicer, payment of the premiums
and fees associated with any Pool Insurance Policy, special hazard insurance
policy, Bankruptcy Bond or, to the extent specified in the related Prospectus
Supplement, other insurance policy or credit support, payment of the fees and
disbursements of the Trustee and independent accountants, and payment of
expenses incurred in connection with distributions and reports to
Securityholders, and payment of any other expenses as described in the related
Prospectus Supplement.
 
     It is anticipated that the administration compensation will in all cases
exceed such expenses. The Master Servicer is entitled to reimbursement for
certain expenses incurred by it in connection with the liquidation of defaulted
Residential Loans, including under certain circumstances reimbursement of
expenditures incurred by it in connection with the restoration of Residential
Properties, such right of reimbursement being prior to the rights of
Securityholders to receive any related Liquidation Proceeds. The Master Servicer
is also entitled to reimbursement from the Trust Account for Advances, if
applicable. With respect to a Series of Securities relating to Agency
Securities, the Trustee shall pay all expenses incurred in administration
thereof, subject to the limitations described in the related Prospectus
Supplement.
 
                                       55
<PAGE>
EVIDENCE AS TO COMPLIANCE
 
     Each Agreement will generally provide that on or before a specified date in
each year, beginning with the first such date that occurs at least six months
after the Cut-off Date, the Master Servicer, in the case of a Pooling and
Servicing Agreement, or the Trustee, in the case of a Trust Agreement, at its
expense shall cause a firm of independent public accountants (who may also
render other services to the Master Servicer, the Depositor, the Trustee or any
affiliate thereof) which is a member of the American Institute of Certified
Public Accountants to furnish a statement to the Depositor and, in the case of a
Pooling and Servicing Agreement, to the Trustee, to the effect that such firm as
part of their examination of the financial statements of the Master Servicer or
the Trustee, as the case may be, has performed tests in accordance with
generally accepted accounting principles regarding the records and documents
relating to residential loans or agency securities serviced and that their
examination disclosed no exceptions that, in their opinion, were material. In
rendering such statement, such firm may rely, as to matters relating to direct
servicing of Residential Loans by Sub-Servicers, upon comparable statements for
examinations conducted substantially in compliance with generally accepted
accounting principles in the residential loan servicing industry (rendered
within one year of such statement) of independent public accountants with
respect to the related Sub-Servicer.
 
     Each Agreement will also provide for delivery to the Depositor and, in the
case of a Servicing Agreement, to the Trustee, on or before a specified date in
each year, of an annual statement signed by two officers of the Master Servicer,
in the case of a Pooling and Servicing Agreement, or of the Trustee, in the case
of a Trust Agreement, to the effect that, to the best of such officers'
knowledge, the Master Servicer or the Trustee, as the case may be, has fulfilled
its obligations under such Agreement throughout the preceding year.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER, THE DEPOSITOR AND THE TRUSTEE
 
THE MASTER SERVICER
 
     The Master Servicer under each Servicing Agreement will be identified in
the related Prospectus Supplement. Each such Servicing Agreement will provide
that the Master Servicer may resign from its obligations and duties under the
Servicing Agreement with the prior written approval of the Depositor and the
Trustee and shall resign upon a determination that its duties thereunder are no
longer permissible under applicable law. No such resignation will become
effective until a successor master servicer meeting the eligibility requirements
set forth in the Servicing Agreement has assumed, in writing, the Master
Servicer's obligations and responsibilities under the Pooling and Servicing
Agreement.
 
     Each Servicing Agreement will further provide that neither the Master
Servicer nor any director, officer, employee, or agent of the Master Servicer
shall 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 Servicing Agreement, or for errors in judgment; provided,
however, that neither the Master Servicer nor any such person shall be protected
against any liability for any breach of warranties or representations made in
the Servicing Agreement or against any specific liability imposed on the Master
Servicer by the terms of the Servicing Agreement or 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. The Master Servicer and any director, officer, employee or agent of
the Master Servicer may rely in good faith on any document of any kind prima
facie properly executed and submitted by any person respecting any matters
arising under the related Servicing Agreement. Each Servicing Agreement will
further provide that the Master Servicer and any director, officer, employee or
agent of the Master Servicer will be entitled to indemnification by the Trust
Fund and will be held harmless against any loss, liability, or expense incurred
in connection with any legal action relating to the Servicing Agreement or the
Securities, the Pool Insurance Policy, the special hazard insurance policy and
the Bankruptcy Bond, if any, other than any loss, liability, or expense related
to any specific Residential Loan or Residential Loans (except any such loss,
liability, or expense otherwise reimbursable pursuant to the Servicing
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 Servicing Agreement will provide that the Master
Servicer will be under no obligation to appear in, prosecute, or defend any
legal action which is not incidental to its duties under the Servicing Agreement
and which in its opinion may involve it in any expense or liability. The Master
Servicer
 
                                       56
<PAGE>
may, however, in its discretion undertake any such action which it may deem
necessary or desirable with respect to the Servicing 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 will be entitled to be reimbursed therefor
out of the Trust Account, such right of reimbursement being prior to the rights
of Securityholders to receive any amount in the Trust Account.
 
     Any entity into which the Master Servicer may be merged, consolidated or
converted, or any entity resulting from any merger, consolidation or conversion
to which the Master Servicer is a party, or any entity succeeding to the
business of the Master Servicer, will be the successor of the Master Servicer
under each Servicing Agreement, provided that the successor or surviving entity
meets the qualifications specified in the related Prospectus Supplement.
 
     If the Prospectus Supplement so provides, the Master Servicer's duties may
be terminated upon payment of a termination fee as specified therein, and the
Master Servicer may be replaced with a successor meeting the qualifications
specified in the Prospectus Supplement.
 
THE DEPOSITOR
 
     Each Servicing Agreement, Owner Trust Agreement and Trust Agreement will
provide that neither the Depositor nor any director, officer, employee, or agent
of the Depositor shall 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 such Agreement, or for errors in judgment;
provided, however, that neither the Depositor nor any such person shall be
protected against any liability for any breach of warranties or representations
made in the Agreement or against any specific liability imposed on the Depositor
by the terms of the Agreement or 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. The Depositor and any
director, officer, employee or agent of the Depositor may rely in good faith on
any document of any kind prima facie properly executed and submitted by any
person respecting any matters arising under the related Agreement. Each
Agreement will further provide that the Depositor and any director, officer,
employee or agent of the Depositor will be entitled to indemnification by the
Trust Fund and will be held harmless against any loss, liability, or expense
incurred in connection with any legal action relating to the Agreement or the
Securities, the Pool Insurance Policy, the special hazard insurance policy and
the Bankruptcy Bond, if any, or the Agency Securities, if any, other than any
loss, liability, or expense related to any specific Residential Loan or
Residential 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
the Depositor will be under no any obligation to appear in, prosecute, or defend
any legal action which is not incidental to its duties under such Agreement and
which in its opinion may involve it in any expense or liability. The Depositor
may, however, in its discretion undertake any such action which it may deem
necessary or desirable with respect to the related Agreement and the rights and
duties of the parties thereto and the interests of the Securityholders
thereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom will be expenses, costs and liabilities of the
Trust Fund, and the Depositor will be entitled to be reimbursed therefor out of
the Trust Account, such right of reimbursement being prior to the rights of
Securityholders to receive any amount in the Trust Account.
 
     Any entity into which the Depositor may be merged, consolidated or
converted, or any entity resulting from any merger, consolidation or conversion
to which the Depositor is a party, or any entity succeeding to the business of
the Depositor will be the successor of the Depositor under each Agreement.
 
THE TRUSTEES
 
     The Trustee for any Series of Securities (or, Trustees, in the case of an
issuance of Notes) will be a corporation possessing corporate trust powers
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state authority and identified in the
related Prospectus Supplement. The commercial bank or trust company serving as
Trustee may have normal banking relationships with the Depositor and its
affiliates and the Master Servicer, if any, and its affiliates. For the purpose
of meeting
 
                                       57
<PAGE>
the legal requirements of certain local jurisdictions, the Depositor and the
Trustee acting jointly shall have the power to appoint co-trustees or separate
trustees of all or any part of the Trust Fund. In the event of such appointment,
all rights, powers, duties and obligations conferred or imposed upon the Trustee
by the Agreement relating to such Series shall be conferred or imposed upon the
Trustee and such separate trustee or co-trustee jointly, or, in any jurisdiction
in which the Trustee shall be incompetent or unqualified to perform certain
acts, singly upon such separate trustee or co-trustee who shall exercise and
perform such rights, powers, duties and obligations solely at the direction of
the Trustee.
 
     The Trustee may resign at any time, in which event the Depositor will be
obligated to appoint a successor Trustee. The Depositor may also remove the
Trustee if the Trustee ceases to be eligible to continue as such under the
Agreement or if the Trustee becomes insolvent, incapable of acting or a receiver
or similar person shall be appointed to take control of its affairs. In such
circumstances, the Depositor will be obligated to appoint a successor Trustee.
The holders of Securities evidencing not less than 51% of the Percentage
Interests of any Series of Securities may at any time remove the Trustee and
appoint a successor Trustee by written instrument in accordance with additional
procedures set forth in the related Agreement. Any resignation or removal of the
Trustee and appointment of a successor Trustee does not become effective until
acceptance of the appointment by a successor Trustee.
 
DUTIES OF THE TRUSTEES
 
     The Trustee will make no representations as to the validity or sufficiency
of any Agreement, the Securities, any Trust Fund Asset or related document other
than the certificate of authentication, and does not assume any responsibility
for their correctness. The Trustee under any Agreement is not accountable for
the use or application by or on behalf of the Master Servicer of any funds paid
to the Master Servicer in respect of the Securities, the Trust Fund Assets, or
deposited into or withdrawn from the Trust Account or any other account by or on
behalf of the Depositor or the Master Servicer. If no Event of Default (as
hereinafter defined) has occurred and is continuing, the Trustee is required to
perform only those duties specifically required under the related Agreement.
However, upon receipt of the various certificates, reports or other instruments
required to be furnished to it under an Agreement, the Trustee is required to
examine such documents and to determine whether they conform to the requirements
of the Agreement.
 
     Each Agreement will further provide that neither the Trustee nor any
director, officer, employee, or agent of the Trustee shall 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
Trustee nor any such person shall be protected against specific liability
imposed on the Trustee by the terms of the Agreement or 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. The Trustee and any director, officer, employee or agent of the
Trustee may rely in good faith on any document of any kind prima facie properly
executed and submitted by any person respecting any matters arising under the
related Agreement. Each Agreement will further provide that the Trustee and any
director, officer, employee or agent of the Trustee will be entitled to
indemnification by the Trust Fund and will be held harmless against any loss,
liability, or expense incurred in connection with any legal action relating to
the Agreement, the Securities or the Agency Securities, if any other than 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.
 
DEFICIENCY EVENTS
 
     With respect to each Series of Securities with Distribution Dates occurring
at intervals less frequently than monthly, and with respect to each Series of
Securities including two or more classes with sequential priorities for
distribution of principal, the following provisions will apply unless otherwise
specified in the related Prospectus Supplement.
 
     A deficiency event (a "Deficiency Event") with respect to the Securities of
any such Series is the inability to distribute to holders of one or more classes
of Securities of such Series, in accordance with the terms thereof and the
related Agreement, any distribution of principal or interest thereon when and as
distributable, in each case because of the insufficiency for such purpose of the
funds then held in the related Trust Fund.
 
                                       58
<PAGE>
     Upon the occurrence of a Deficiency Event, the Trustee or Master Servicer,
as set forth in the related Prospectus Supplement, will be required to determine
whether or not the application on a monthly basis (regardless of frequency of
regular Distribution Dates) of all future scheduled payments on the Residential
Loans included in the related Trust Fund and other amounts receivable with
respect to such Trust Fund towards payments on such Securities in accordance
with the priorities as to distributions of principal and interest set forth in
such Securities will be sufficient to make distributions of interest at the
applicable Security Interest Rates and to distribute in full the principal
balance of each such Security on or before the latest Final Distribution Date of
any outstanding Securities of such Series.
 
     The Trustee or Master Servicer will obtain and rely upon an opinion or
report of a firm of independent accountants of recognized national reputation as
to the sufficiency of the amounts receivable with respect to such Trust Fund to
make such distributions on the Securities, which opinion or report will be
conclusive evidence as to such sufficiency. Prior to making any such
determination, distributions on the Securities shall continue to be made in
accordance with their terms.
 
     In the event that the Trustee or Master Servicer makes a positive
determination, the Trustee or Master Servicer will apply all amounts received in
respect of the related Trust Fund (after payment of expenses of the Trust Fund)
to distributions on the Securities of such Series in accordance with their
terms, except that such distributions shall be made monthly and without regard
to the amount of principal that would otherwise be distributable on any
Distribution Date. Under certain circumstances following such positive
determination, the Trustee or Master Servicer may resume making distributions on
such Securities expressly in accordance with their terms.
 
     If the Trustee or Master Servicer is unable to make the positive
determination described above, the Trustee or Master Servicer will apply all
amounts received in respect of the related Trust Fund (after payment of
expenses) to monthly distributions on the Certificates of such Series pro rata,
without regard to the priorities as to distribution of principal set forth in
such Securities, and such Securities will, to the extent permitted by applicable
law, accrue interest at the highest Security Interest Rate borne by any Security
of such Series, or in the event any class of such Series shall have an
adjustable or variable Security Interest Rate, at the weighted average Security
Interest Rate, calculated on the basis of the maximum Security Interest Rate
applicable to the class having the initial Security Principal Balance of the
Securities of that class. In such event, the holders of Securities evidencing a
majority of the Voting Rights may direct the Trustee to sell the related Trust
Fund, any such direction being irrevocable and binding upon the holders of all
Securities of such Series and upon the owners of any residual interests in such
Trust Fund. In the absence of such a direction, the Trustee may not sell all or
any portion of the Trust Fund.
 
EVENTS OF DEFAULT
 
POOLING AND SERVICING AGREEMENTS
 
     Events of default ("Events of Default") under each Pooling and Servicing
Agreement will generally consist of (i) any failure by the Master Servicer to
distribute or cause to be distributed to Certificateholders 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 Certificates
evidencing not less than 25% of the Percentage Interests in the related Trust
Fund; (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
continues unremedied for sixty 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 Certificates
evidencing not less than 25% of the Percentage Interests in the related Trust
Fund; and (iii) certain events of insolvency, readjustment of debt, marshalling
of assets and liabilities or similar proceedings and certain actions by or on
behalf of the Master Servicer indicating its insolvency or inability to pay its
obligations. A default pursuant to the terms of any Mortgage Securities included
in any Trust Fund will not constitute an Event of Default under the related
Pooling and Servicing Agreement.
 
     So long as an Event of Default under a Pooling and Servicing Agreement
remains unremedied, the Depositor or the Trustee may, and at the direction of
holders of Certificates evidencing not less than 25% of the Percentage Interests
shall, by notice in writing to the Master Servicer terminate all of the rights
and obligations of the Master Servicer under the Pooling and Servicing Agreement
and in and to the Residential Loans and the
 
                                       59
<PAGE>
proceeds thereof. Upon receipt by the Master Servicer of such written notice,
all authority and power of the Master Servicer under this Pooling and Servicing
Agreement shall pass to and be vested in the Trustee, and the Trustee shall be
authorized and empowered to execute and deliver, on behalf of the Master
Servicer, as attorney-in-fact, or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such termination. Upon receipt by the
Master Servicer of notice of termination, the Trustee will succeed to all the
responsibilities, duties and liabilities of the Master Servicer under the
Pooling and Servicing Agreement (except that if the Trustee is prohibited by law
from obligating itself to make advances regarding delinquent Residential Loans,
then the Trustee will not be so obligated) and will be entitled to similar
compensation arrangements. In the event that the Trustee is unwilling, it may,
or if it is unable or if the holders of Certificates evidencing not less than
25% of the Percentage Interests request in writing, it shall appoint, or
petition a court of competent jurisdiction for the appointment of, a residential
loan servicing institution with a net worth of at least $10,000,000 to act as
successor to the Master Servicer under the Pooling and Servicing Agreement.
Pending such appointment, the Trustee is obligated to act in such capacity. The
Trustee and such successor may agree upon the administration compensation to be
paid, which in no event may be greater than the compensation to the Master
Servicer under the Pooling and Servicing Agreement.
 
     No Certificateholder will have the right under any Pooling and Servicing
Agreement to institute any proceeding with respect thereto unless: (i) such
holder previously has given to the Trustee written notice of an Event of Default
or of a default by the Depositor or the Trustee in the performance of any
obligation under the Pooling and Servicing Agreement, and of the continuance
thereof; (ii) the holders of Certificates evidencing not less than 25% of the
Percentage Interests 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 as it may require against the costs, expenses and
liabilities to be incurred thereby; and (iii) the Trustee for sixty days after
receipt of such notice, request and offer of indemnity has neglected or refused
to institute any such proceeding. The Trustee, however, is under no obligation
to exercise any of the trusts or powers vested in it by any Pooling and
Servicing Agreement or to make any investigation of matters arising thereunder
or to institute, conduct, or defend any litigation thereunder or in relation
thereto at the request, order or direction of any of the holders of Certificates
covered by such Pooling and Servicing Agreement, unless such Certificateholders
have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby.
 
SERVICING AGREEMENT
 
     Unless otherwise provided in the related Prospectus Supplement for a Series
of Notes, a "Servicing Default" under the related Servicing Agreement generally
will include: (i) any failure by the Master Servicer to make a required deposit
to the Security Account or, if the Master Servicer is so required, to distribute
to the holders of any class of Notes or Equity Certificates of such Series any
required payment which continues unremedied for five business days (or other
period of time described in the related Prospectus Supplement) after the giving
of written notice of such failure to the Master Servicer by the Trustee or the
Issuer; (ii) any failure by the Master Servicer duly to observe or perform in
any material respect any other of its covenants or agreements in the Servicing
Agreement with respect to such Series of Securities which continues unremedied
for 45 days after the giving of written notice of such failure to the Master
Servicer by the Trustee or the Issuer; (iii) certain events of insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings regarding the Master Servicer and certain actions by the Master
Servicer indicating its insolvency or inability to pay its obligations and (iv)
any other Servicing Default as set forth in the Servicing Agreement.
 
     So long as a Servicing Default remains unremedied, either the Depositor or
the Trustee may, by written notification to the Master Servicer and to the
Issuer or the Trustee or Trust Fund, as applicable, terminate all of the rights
and obligations of the Master Servicer under the Servicing Agreement (other than
any right of the Master Servicer as Noteholder or as holder of the Equity
Certificates and other than the right to receive servicing compensation and
expenses for servicing the Mortgage Loans during any period prior to the date of
such termination), whereupon the Trustee will succeed to all responsibilities,
duties and liabilities of the Master Servicer under such Servicing Agreement
(other than the obligation to purchase Mortgage Loans under certain
circumstances) and will be entitled to similar compensation arrangements. In the
event that the Trustee would be obligated to succeed the Master Servicer but is
unwilling so to act, it may appoint (or if it is unable so to act, it
 
                                       60
<PAGE>
shall appoint) or petition a court of competent jurisdiction for the appointment
of an approved mortgage servicing institution with a net worth of at least
$10,000,000 to act as successor to the Master Servicer under the Servicing
Agreement (unless otherwise set forth in the Servicing Agreement). Pending such
appointment, the Trustee is obligated to act in such capacity. The Trustee and
such successor may agree upon the servicing compensation to be paid, which in no
event may be greater than the compensation to the initial Master Servicer under
the Servicing Agreement.
 
INDENTURE
 
     Unless otherwise provided in the related Prospectus Supplement for a Series
of Notes, an Event of Default under the Indenture generally will include: (i) a
default for five days or more (or other period of time described in the related
Prospectus Supplement) in the payment of any principal of or interest on any
Note of such Series; (ii) failure to perform any other covenant of the Issuer or
the Trust Fund in the Indenture which continues for a period of thirty days
after notice thereof is given in accordance with the procedures described in the
related Prospectus Supplement; (iii) any representation or warranty made by the
Issuer or the Trust Fund in the Indenture or in any certificate or other writing
delivered pursuant thereto or in connection therewith with respect to or
affecting such Series having been incorrect in a material respect as of the time
made, and such breach is not cured within thirty days after notice thereof is
given in accordance with the procedures described in the related Indenture; (iv)
certain events of bankruptcy, insolvency, receivership or liquidation of the
Issuer or the Trust Fund; or (v) any other Event of Default provided with
respect to Notes of that Series.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, the Trustee or the holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may declare
the principal amount (or, if the Notes of that Series are Accrual Securities,
such portion of the principal amount as may be specified in the terms of that
Series, as provided in the related Prospectus Supplement) of all the Notes of
such Series to be due and payable immediately. Such declaration may, under
certain circumstances, be rescinded and annulled by the holders of a majority in
aggregate outstanding amount of the related Notes.
 
     If following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Trustee may,
in its discretion, notwithstanding such acceleration, elect to maintain
possession of the collateral securing the Notes of such Series and to continue
to apply payments on such collateral as if there had been no declaration of
acceleration if such collateral continues to provide sufficient funds for the
payment of principal of and interest on the Notes of such Series as they would
have become due if there had not been such a declaration. In addition, the
Trustee may not sell or otherwise liquidate the collateral securing the Notes of
a Series following an Event of Default, unless (a) the holders of 100% of the
then aggregate outstanding amount of the Notes of such Series consent to such
sale, (b) the proceeds of such sale or liquidation are sufficient to pay in full
the principal of and accrued interest, due and unpaid, on the outstanding Notes
of such Series at the date of such sale or (c) the Trustee determines that such
collateral would not be sufficient on an ongoing basis to make all payments on
such Notes as such payments would have become due if such Notes had not been
declared due and payable, and the Trustee obtains the consent of the holders of
66 2/3% of the then aggregate outstanding amount of the Notes of such Series.
 
     In the event that the Trustee liquidates the collateral in connection with
an Event of Default, the Indenture provides that the Trustee will have a prior
lien on the proceeds of any such liquidation for unpaid fees and expenses. As a
result, upon the occurrence of such an Event of Default, the amount available
for payments to the Noteholders would be less than would otherwise be the case.
However, the Trustee may not institute a proceeding for the enforcement of its
lien except in connection with a proceeding for the enforcement of the lien of
the Indenture for the benefit of the Noteholders after the occurrence of such an
Event of Default.
 
     In the event the principal of the Notes of a Series is declared due and
payable, as described above, the holders of any such Notes issued at a discount
from par may be entitled to receive no more than an amount equal to the unpaid
principal amount thereof less the amount of such discount that is unamortized.
 
     No Noteholder or holder of an Equity Certificate generally will have any
right under an Owner Trust Agreement or Indenture to institute any proceeding
with respect to such Agreement unless (a) such holder previously has given to
the Trustee written notice of default and the continuance thereof, (b) the
holders of Notes or Equity Certificates of any class evidencing not less than
25% of the aggregate Percentage Interests constituting
 
                                       61
<PAGE>
such class (i) have made written request upon the Trustee to institute such
proceeding in its own name as Trustee thereunder and (ii) have offered to the
Trustee reasonable indemnity, (c) the Trustee has neglected or refused to
institute any such proceeding for 60 days after receipt of such request and
indemnity and (d) no direction inconsistent with such written request has been
given to the Trustee during such 60 day period by the Holders of a majority of
the Note Balances of such class. However, the Trustee will be under no
obligation to exercise any of the trusts or powers vested in it by the
applicable Agreement or to institute, conduct or defend any litigation
thereunder or in relation thereto at the request, order or direction of any of
the holders of Notes or Equity Certificates covered by such Agreement, unless
such holders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred therein or
thereby.
 
AMENDMENT
 
     Each Agreement may be amended by the Depositor, the Trustee and, in the
case of a Pooling and Servicing Agreement, the Master Servicer, (i) to cure any
ambiguity, (ii) to correct or supplement any provision therein which may be
inconsistent with any other provision therein, (iii) to make any other
provisions with respect to matters or questions arising under the Agreement and
(iv) if such amendment, as evidenced by an opinion of counsel, is reasonably
necessary to comply with any requirements imposed by the Code (or any successor
or mandatory statutes) or any temporary or final regulation, revenue ruling,
revenue procedure or other written official announcement or interpretation
relating to federal income tax law or any proposed such action which, if made
effective, would apply retroactively to the Trust Fund at least from the
effective date of such amendment, each without the consent of any of the
Certificateholders of the related Series, provided that such action (other than
an amendment described in (iv) above) will not adversely affect in any material
respect the interests of any holder of the Certificates covered by the
Agreement. Each Agreement may also be amended, subject to certain restrictions
to continue favorable tax treatment of the entity by the Depositor, the Trustee
and, in the case of a Pooling and Servicing Agreement the Master Servicer, with
the consent of the holders of Certificates evidencing not less than 51% of the
Percentage Interests of the related Series for any purpose; provided, however,
that no such amendment may (a) reduce in any manner the amount of, or delay the
timing of, payments received on Trust Fund Assets which are required to be
distributed on any Certificate without the consent of the holder of such
Certificate, or (b) reduce the aforesaid percentage of Percentage Interests
required for the consent to any such amendment without the consent of the
holders of all Certificates of the related Series then outstanding.
 
     With respect to each Series of Notes, each related Servicing Agreement or
Indenture may be amended by the parties thereto without the consent of any of
the holders of the Notes covered by such Agreement, to cure any ambiguity, to
correct, modify or supplement any provision therein, or to make any other
provisions with respect to matters or questions arising under the Agreement
which are not inconsistent with the provisions thereof, provided that such
action will not adversely affect in any material respect the interests of any
holder of Notes covered by the Agreement. Each Agreement may also be amended by
the parties thereto with the consent of the holders of Notes evidencing not less
than 66 2/3% of the voting rights, for any purpose; provided, however, that no
such amendment may (i) reduce in any manner the amount of or delay the timing
of, payments received on Trust Fund Assets which are required to be distributed
on any Note without the consent of the holder of such Note, (ii) adversely
affect in any material respect the interests of the holders of any class of
Notes in a manner other than as described in (i), without the consent of the
holders of Notes of such class evidencing not less than 66 2/3% of the aggregate
voting rights of such class or (iii) reduce the aforesaid percentage of voting
rights required for the consent to any such amendment without the consent of the
holders of all Notes covered by such Agreement then outstanding. The voting
rights evidenced by any Note will be the portion of the voting rights of all of
the Notes in the related Series allocated in the manner described in the related
Prospectus Supplement.
 
TERMINATION
 
     The obligations created by the Agreement for each Series of Securities will
terminate upon payment to the Securityholders of that Series of all amounts held
in the Trust Account and required to be paid to the Securityholders pursuant to
such Agreement, following the final payment or other liquidation, including the
disposition of all property acquired upon foreclosure or repossession, of the
last Trust Fund Asset remaining in the related Trust Fund or, the purchase of
all of the assets of the Trust Fund by the party entitled to effect such
termination, under the circumstances and in the manner set forth in the related
Prospectus Supplement, whichever occurs first. In no event, however, will the
trust created by the Agreement continue beyond the period specified in the
related Prospectus Supplement. Written notice of termination of the Agreement
will be given to each
 
                                       62
<PAGE>
Securityholder, and the final distribution will be made only upon surrender and
cancellation of the Securities at an office or agency appointed by the Trustee
which will be specified in the notice of termination.
 
     Any such purchase of assets of the Trust Fund shall be made at a price
equal to (a) in the case of a Series of Securities evidencing interests in a
Trust Fund that includes Residential Loans, the sum of (i) 100% of the unpaid
principal balance of each outstanding Residential Loan (net of any unreimbursed
Advances attributable to principal) as of the date of such purchase plus accrued
interest thereon at the Net Interest Rate to the first day of the month of such
purchase, plus (ii) the appraised value of any property acquired in respect of
any defaulted Residential Loan (but not more than the unpaid principal balance
of that Residential Loan) together with accrued interest at the applicable Net
Interest Rate to the first day of the month of such purchase less the good faith
estimate of the Master Servicer of liquidation expenses to be incurred in
connection with its disposal thereof, and (b) in the case of a Series of
Securities evidencing interests in a Trust Fund that includes Agency Securities
or Mortgage Securities, the sum of 100% of the unpaid principal balance of each
outstanding Trust Fund Asset as of the day of such purchase plus accrued
interest thereon at the Net Interest Rate to the first day of the month of such
purchase, or at such other price as may be specified in the related Prospectus
Supplement. The exercise of the right to purchase the assets of the Trust Fund
as set forth in the preceding paragraph will effect early retirement of the
Securities of that Series.
 
VOTING RIGHTS
 
     If so provided in the related Agreement, a provider of credit support may
be entitled to direct certain actions of the Master Servicer and the Trustee or
to exercise certain rights of the Master Servicer, the Trustee or the holders of
Securities.
 
                   DESCRIPTION OF PRIMARY INSURANCE COVERAGE
 
     If provided in the related Prospectus Supplement, each Residential Loan
will be covered by a Primary Hazard Insurance Policy (as defined herein) and, if
required as described in the related Prospectus Supplement, a Primary Credit
Insurance Policy. In addition, if provided in the related Prospectus Supplement,
a Trust Fund may include any combination of a Pool Insurance Policy, a special
hazard insurance policy, a Bankruptcy Bond or another form of credit support, as
described under "Description of Credit Support."
 
     The following is only a brief description of certain insurance policies and
does not purport to summarize or describe all of the provisions of these
policies. Such insurance is subject to underwriting and approval of individual
Residential Loans by the respective insurers.
 
PRIMARY CREDIT INSURANCE POLICIES
 
     If provided in the related Prospectus Supplement and as set forth under
"Description of the Certificates--Realization Upon Defaulted Residential Loans,"
the Master Servicer will maintain or cause to be maintained in accordance with
the underwriting standards adopted by the Depositor a Primary Credit Insurance
Policy with respect to each Residential Loan (other than Multifamily Loans, FHA
Loans, and VA Loans) for which such insurance is required. While the terms and
conditions of Primary Credit Insurance Policies differ, each Primary Credit
Insurance Policy generally will cover losses up to an amount equal to the excess
of the outstanding principal balance of a defaulted Residential Loan (plus
accrued and unpaid interest thereon and certain approved expenses) over a
specified percentage of the Collateral Value of the related Residential
Property.
 
     The Master Servicer will cause to be paid the premium for each Primary
Credit Insurance Policy on a timely basis. The Master Servicer, or the related
Sub-Servicer, if any, will exercise its best reasonable efforts to be named the
insured or a loss payee under any Primary Credit Insurance Policy. The ability
to assure that insurance proceeds are appropriately applied may be dependent
upon its being so named, or upon the extent to which information in this regard
is furnished by borrowers. All amounts collected by the Master Servicer under
any such policy will be deposited in the Trust Account. The Master Servicer will
not cancel or refuse to renew any such Primary Credit Insurance Policy in effect
at the time of the initial issuance of the Securities that is required to be
kept in force under the related Agreement unless the Master Servicer uses its
best efforts to obtain a replacement Primary Credit Insurance Policy for such
canceled or nonrenewed policy maintained with an insurer the claims-paying
ability of which is acceptable to the Rating Agency or Agencies for pass-through
certificates having the same rating as the Securities on their date of issuance.
 
                                       63
<PAGE>
     As conditions precedent to the filing or payment of a claim under a Primary
Credit Insurance Policy, the insured typically will be required, in the event of
default by the borrower, among other things, to: (i) advance or discharge (a)
hazard insurance premiums and (b) as necessary and approved in advance by the
insurer, real estate taxes (if applicable), protection and preservation expenses
and foreclosure and related costs; (ii) in the event of any physical loss or
damage to the Residential Property, have the Residential Property restored to at
least its condition at the effective date of the Primary Credit Insurance Policy
(ordinary wear and tear excepted); and (iii) tender to the insurer good and
merchantable title to, and possession of, the Residential Property.
 
FHA INSURANCE AND VA GUARANTEES
 
     Residential 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 1934, as amended. Certain Residential 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, the FHA 245
graduated payment mortgage program and the FHA Title I Program. These programs
generally limit the principal amount and interest rates of the mortgage loans
insured. The Prospectus Supplement for Securities of each Series evidencing
interests in a Trust Fund including FHA Loans will set forth additional
information regarding the regulations governing the applicable FHA insurance
programs. Except as otherwise specified in the related Prospectus Supplement,
the following describes FHA insurance programs and regulations as generally in
effect with respect to FHA Loans.
 
     The insurance premiums for FHA Loans are collected by lenders approved by
the Department of Housing and Urban Development ("HUD") or by the Master
Servicer or any Sub-Servicer and are paid to the FHA. The regulations governing
FHA single-family mortgage insurance programs provide that insurance benefits
are payable either upon foreclosure (or other acquisition of possession) and
conveyance of the mortgaged premises to the United States of America or upon
assignment of the defaulted Loan to the United States of America. With respect
to a defaulted FHA-insured Residential Loan, the Master Servicer or any
Sub-Servicer is limited in its ability to initiate foreclosure proceedings. When
it is determined, either by the Master Servicer or any Sub-Servicer or HUD, that
default was caused by circumstances beyond the mortgagor's control, the Master
Servicer or any Sub-Servicer is expected to make an effort to avoid foreclosure
by entering, if feasible, into one of a number of available forms of forbearance
plans with the mortgagor. Such plans may involve the reduction or suspension of
regular mortgage payments for a specified period, with such payments to be made
upon or before the maturity date of the mortgage, or the recasting of payments
due under the mortgage up to or, other than Residential Loans originated under
the Title I Program of the FHA, beyond the maturity date. In addition, when a
default caused by such circumstances is accompanied by certain other criteria,
HUD may provide relief by making payments to the Master Servicer or any
Sub-Servicer in partial or full satisfaction of amounts due under the
Residential Loan (which payments are to be repaid by the mortgagor to HUD) or by
accepting assignment of the loan from the Master Servicer or any Sub-Servicer.
With certain exceptions, at least three full monthly installments must be due
and unpaid under the FHA Loan, and HUD must have rejected any request for relief
from the mortgagor before the Master Servicer or any Sub-Servicer may initiate
foreclosure proceedings.
 
     HUD has the option, in most cases, to pay insurance claims in cash or in
debentures issued by HUD. Currently, claims are being paid in cash, and claims
have not been paid in debentures since 1965. HUD debentures issued in
satisfaction of FHA insurance claims bear interest at the applicable HUD
debentures interest rate. Unless otherwise provided in the related Prospectus
Supplement, the Master Servicer or any Sub-Servicer of each FHA-insured single
family Loan will be obligated to purchase any such debenture issued in
satisfaction of such Residential Loan upon default for an amount equal to the
principal amount of any such debenture.
 
     Other than in relation to the Title I Program of the FHA, the amount of
insurance benefits generally paid by the FHA is equal to the entire unpaid
principal amount of the defaulted Residential Loan adjusted to reimburse the
Master Servicer or Sub-Servicer for certain costs and expenses and to deduct
certain amounts received or retained by the Master Servicer or Sub-Servicer
after default. When entitlement to insurance benefits results from foreclosure
(or other acquisition of possession) and conveyance to HUD, the Master Servicer
or Sub-Servicer is compensated for no more than two-thirds of its foreclosure
costs, and is compensated for interest accrued and unpaid prior to such date but
in general only to the extent it was allowed pursuant to a forbearance plan
approved by HUD. When entitlement to insurance benefits results from assignment
of the Residential Loan to HUD, the insurance payment includes full compensation
for interest accrued and unpaid to the assignment date. The
 
                                       64
<PAGE>
insurance payment itself, upon foreclosure of an FHA-insured Residential Loan,
bears interest from a date 30 days after the borrower's first uncorrected
failure to perform any obligation to make any payment due under the mortgage
and, upon assignment, from the date of assignment to the date of payment of the
claim, in each case at the same interest rate as the applicable HUD debenture
interest rate as described above.
 
     Residential 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 Policy"). 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 guarantee
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
guarantee of mortgage loans of up to 30 years' duration. However, no Residential
Loan guaranteed by the VA will have an original principal amount greater than
five times the partial VA guarantee for such Residential Loan. The Prospectus
Supplement for Securities of each Series evidencing interests in a Trust Fund
including VA Loans will set forth additional information regarding the
regulations governing the applicable VA insurance programs.
 
     With respect to a defaulted VA guaranteed Residential Loan, the Master
Servicer or Sub-Servicer is, absent exceptional circumstances, authorized to
announce its intention to foreclose only when the default has continued for
three months. Generally, a claim for the guarantee is submitted after
liquidation of the Residential Property.
 
     The amount payable under the guarantee will be the percentage of the
VA-insured Residential Loan originally guaranteed applied to indebtedness
outstanding as of the applicable date of computation specified in the VA
regulations. Payments under the guarantee will be equal to the unpaid principal
amount of the Residential Loan, interest accrued on the unpaid balance of the
Residential Loan to the appropriate date of computation and limited expenses of
the mortgagee, but in each case only to the extent that such amounts have not
been recovered through liquidation of the Residential Property. The amount
payable under the guarantee may in no event exceed the amount of the original
guarantee.
 
PRIMARY HAZARD INSURANCE POLICIES
 
     Unless otherwise provided in the Prospectus Supplement in respect of a
Series, the related Servicing Agreement will require the Master Servicer to
cause the borrower on each Residential Loan to maintain a hazard insurance
policy (a "Primary Hazard Insurance Policy") providing for coverage of the
standard form of fire insurance policy with extended coverage customary in the
state in which the Residential Property is located. Unless otherwise specified
in the related Prospectus Supplement, such coverage in general will equal the
lesser of the principal balance owing on such Residential Loan and the amount
necessary to fully compensate for any damage or loss to the improvements on the
Residential Property on a replacement cost basis, but in either case not less
than the amount necessary to avoid the application of any co-insurance clause
contained in the policy. The Master Servicer, or the related Sub-Servicer, if
any, will exercise its best reasonable efforts to be named as an additional
insured under any Primary Hazard Insurance Policy and under any flood insurance
policy referred to below. The ability to assure that hazard insurance proceeds
are appropriately applied may be dependent upon its being so named, or upon the
extent to which information in this regard is furnished by borrowers. All
amounts collected by the Master Servicer under any such policy (except for
amounts to be applied to the restoration or repair of the Residential Property
or released to the borrower in accordance with the Master Servicer's normal
servicing procedures, subject to the terms and conditions of the related
Mortgage and Mortgage Note) will be deposited in the Trust Account. Each
Servicing Agreement provides that the Master Servicer may satisfy its obligation
to cause each borrower to maintain such a hazard insurance policy by the Master
Servicer's maintaining a blanket policy insuring against hazard losses on the
Residential Loans. If such blanket policy contains a deductible clause, the
Master Servicer will deposit in the Trust Account all sums which would have been
deposited therein but for such clause. The Master Servicer also is required to
maintain a fidelity bond and errors and omissions policy with respect to its
officers and employees that provides coverage against losses that may be
sustained as a result of an officer's or employee's misappropriation of funds or
errors and omissions in failing to maintain insurance, subject to certain
limitations as to amount of coverage, deductible amounts, conditions, exclusions
and exceptions.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements of the property by fire,
lightning, explosion, smoke, windstorm and hail, and riot, strike and
 
                                       65
<PAGE>
civil commotion, subject to the conditions and exclusions specified in each
policy. Although the policies relating to the Residential Loans will be
underwritten by different insurers under different state laws in accordance with
different applicable state forms, and therefore will not contain identical terms
and conditions, the basic terms thereof are dictated by respective state laws,
and most such policies typically do not cover any physical damage resulting from
the following: war, revolution, governmental actions, floods and other
water-related causes, earth movement (including earthquakes, landslides and
mudflows), nuclear reactions, wet or dry rot, vermin, rodents, insects or
domestic animals, theft, and, in certain cases, vandalism. The foregoing list is
merely indicative of certain kinds of uninsured risks and is not intended to be
all-inclusive. When a Residential Property is located at origination in a
federally designated flood area, each Servicing Agreement requires the Master
Servicer to cause the borrower to acquire and maintain flood insurance in an
amount equal in general to the lesser of (i) the amount necessary to fully
compensate for any damage or loss to the improvements which are part of the
Residential Property on a replacement cost basis and (ii) the maximum amount of
insurance available under the federal flood insurance program, whether or not
the area is participating in the program.
 
     The hazard insurance policies covering the Residential Properties typically
contain a co-insurance clause that in effect requires the insured at all times
to carry insurance of a specified percentage (generally 80% to 90%) of the full
replacement value of the improvements on the property in order to recover the
full amount of any partial loss. If the insured's coverage falls below this
specified percentage, such clause generally provides that the insurer's
liability in the event of partial loss does not exceed the greater of (i) the
replacement cost of the improvements less physical depreciation and (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.
 
     The Master Servicer will not require that a hazard or flood insurance
policy be maintained for any Cooperative Loan. Generally, the Cooperative 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 Note do not maintain such insurance or
do not maintain adequate coverage or any insurance proceeds are not applied to
the restoration of the damaged property, damage to such borrower's Cooperative
apartment or such Cooperative's building could significantly reduce the value of
the collateral securing such Cooperative Note.
 
     Since the amount of hazard insurance the Master Servicer will cause to be
maintained on the improvements securing the Residential Loans will decline as
the principal balances owing thereon decrease, and since residential properties
have historically appreciated in value over time, the effect of co-insurance in
the event of partial loss may be that hazard insurance proceeds may be
insufficient to restore fully the damaged property. Under the terms of the
Residential Loans, borrowers are required to present claims to insurers under
hazard insurance policies maintained on the Residential Properties. The Master
Servicer, on behalf of the Trustee and Certificateholders, is obligated to
present or cause to be presented claims under any blanket insurance policy
insuring against hazard losses on Residential Properties. The ability of the
Master Servicer to present or cause to be presented such claims is dependent
upon the extent to which information in this regard is furnished to the Master
Servicer by borrowers. However, if provided in the related Prospectus
Supplement, to the extent of the amount available to cover hazard losses under
the special hazard insurance policy for a Series, Certificateholders will not
suffer loss by reason of delinquencies or foreclosures following hazard losses,
whether or not subject to co-insurance claims.
 
                         DESCRIPTION OF CREDIT SUPPORT
 
     If so provided in the related Prospectus Supplement, the Trust Fund that
includes Residential Loans for a Series of Securities may include credit support
for such Series or for one or more classes of Securities comprising such Series,
which credit support may consist of any combination of the following separate
components, any of which may be limited to a specified percentage of the
aggregate principal balance of the Residential Loans covered thereby or a
specified dollar amount: a Pool Insurance Policy, a special hazard insurance
policy, a Bankruptcy Bond, a reserve fund, or a similar credit support
instrument. Alternatively, if so specified in the Prospectus Supplement for a
Series of Securities, credit support may be provided by subordination of one or
more classes of Securities, in combination with or in lieu of any one or more of
the instruments set forth above. See "Description of the
Securities--Subordination." The amount and type of credit support with respect
to a
 
                                       66
<PAGE>
Series of Securities or with respect to one or more classes of Securities
comprising such Series, and the obligors on such credit support, will be set
forth in the related Prospectus Supplement.
 
     To the extent provided in the related Prospectus Supplement and the
Agreement, credit support may be periodically reduced based on the aggregate
outstanding principal balance of the Residential Loans covered thereby.
 
POOL INSURANCE POLICIES
 
     If so specified in the Prospectus Supplement relating to a Series of
Securities, the Master Servicer will exercise its best reasonable efforts to
maintain or cause to be maintained a Pool Insurance Policy in full force and
effect, unless coverage thereunder has been exhausted through payment of claims.
The Pool Insurance Policy for any Series of Securities will be issued by the
Pool Insurer named in the related Prospectus Supplement. Each Pool Insurance
Policy will, subject to the limitations described below, provide coverage in an
amount equal to a percentage (specified in the related Prospectus Supplement) of
the aggregate principal balance of the Residential Loans on the Cut-off Date.
The Master Servicer will pay the premiums for each Pool Insurance Policy on a
timely basis unless, as described in the related Prospectus Supplement, the
payment of such fees is otherwise provided. The Master Servicer will present or
cause to be presented claims under each Pool Insurance Policy to the Pool
Insurer on behalf of itself, the Trustee and the Securityholders. Pool Insurance
Policies, however, are not blanket policies against loss, since claims
thereunder may be made only upon satisfaction of certain conditions, as
described below and, if applicable, in the related Prospectus Supplement.
 
     Pool Insurance Policies do not cover losses arising out of the matters
excluded from coverage under Primary Credit Insurance Policies, FHA Insurance or
VA Guarantees or losses due to a failure to pay or denial of a claim under a
Primary Credit Insurance Policy, FHA Insurance or VA Guarantee, irrespective of
the reason therefor.
 
     Pool Insurance Policies in general provide that no claim may be validly
presented thereunder with respect to a residential loan unless (i) an acceptable
Primary Credit Insurance Policy, in the event that the initial Collateral Value
of the Residential Loan exceeded 80%, has been kept in force until such
Collateral Value is reduced to 80%; (ii) premiums on the Primary Hazard
Insurance Policy have been paid by the insured and real estate taxes (if
applicable) and foreclosure, protection and preservation expenses have been
advanced by or on behalf of the insured, as approved by the Pool Insurer; (iii)
if there has been physical loss or damage to the Residential Property, it has
been restored to its physical condition at the time the Residential Loan became
insured under the Pool Insurance Policy, subject to reasonable wear and tear;
and (iv) the insured has acquired good and merchantable title to the Residential
Property, free and clear of all liens and encumbrances, except permitted
encumbrances, including any right of redemption by or on behalf of the borrower,
and if required by the Pool Insurer, has sold the property with the approval of
the Pool Insurer.
 
     Assuming the satisfaction of these conditions, the Pool Insurer typically
has the option to either (i) acquire the property securing the defaulted
Residential Loan for a payment equal to the principal balance thereof plus
accrued and unpaid interest at the Interest Rate to the date of acquisition and
certain expenses described above advanced by or on behalf of the insured, on
condition that the Pool Insurer must be provided with good and merchantable
title to the Residential Property (unless the property has been conveyed
pursuant to the terms of the applicable Primary Credit Insurance Policy) or (ii)
pay the amount by which the sum of the principal balance of the defaulted
Residential Loan and accrued and unpaid interest at the Interest Rate to the
date of the payment of the claim and such expenses exceeds the proceeds received
from a sale of the Residential Property that the Pool Insurer has approved. In
both (i) and (ii), the amount of payment under a Pool Insurance Policy will be
reduced by the amount of such loss paid under any Primary Credit Insurance
Policy.
 
     Unless earlier directed by the Pool Insurer, a claim under a Pool Insurance
Policy generally must be filed (i) in the case when a Primary Credit Insurance
Policy is in force, within a specified number of days (typically, 60 days) after
the claim for loss has been settled or paid thereunder, or after acquisition by
the insured or a sale of the property approved by the Pool Insurer, whichever is
later, or (ii) in the case when a Primary Credit Insurance Policy is not in
force, within a specified number of days (typically, 60 days) after acquisition
by the insured or a sale of the property approved by the Pool Insurer. A claim
must be paid within a specified period (typically, 30 days) after the claim is
made by the insured.
 
                                       67
<PAGE>
     Unless otherwise specified in the Prospectus Supplement relating to a
Series of Securities, the amount of coverage under each Pool Insurance Policy
will be reduced over the life of the Securities of such Series by the aggregate
dollar amount of claims paid less the aggregate of the net amounts realized by
the Pool Insurer upon disposition of all acquired properties. The amount of
claims paid includes certain expenses incurred by the Master Servicer as well as
accrued interest on delinquent Residential Loans to the date of payment of the
claim. However, Securityholders may experience a shortfall in the amount of
interest distributed in connection with the payment of claims under a Pool
Insurance Policy, because the Pool Insurer is required to remit only unpaid
interest through the date a claim is paid, rather than unpaid interest through
the end of the month in which such claim is paid. In addition, Securityholders
may experience losses in connection with payments made under a Pool Insurance
Policy to the extent that the Master Servicer expends funds for the purpose of
enabling it to make a claim under such Pool Insurance Policy. Such expenditures
could include amounts necessary to cover real estate taxes and to repair the
related Residential Property. The Master Servicer will be reimbursed for such
expenditures from amounts that otherwise would be distributed to
Securityholders, and such expenditures will not be covered by payments made
under the related Pool Insurance Policy. See "Certain Legal Aspects of
Residential Loans--Foreclosure on Mortgages" and "--Repossession with respect to
Manufactured Housing Contracts." Accordingly, if aggregate net claims paid under
a Pool Insurance Policy reach the applicable policy limit, coverage under that
Pool Insurance Policy will be exhausted and any further losses will be borne by
Securityholders of the related Series.
 
     In the event that a Pool Insurer ceases to be a Qualified Insurer (such
term being defined to mean a private mortgage guaranty insurance company duly
qualified as such under applicable laws and approved as an insurer by FHLMC,
FNMA, or any successor entity, and having a claims-paying ability acceptable to
the Rating Agency or Agencies), the Master Servicer will use its best reasonable
efforts to obtain or cause to be obtained from another Qualified Insurer a
replacement insurance policy comparable to the Pool Insurance Policy with a
total coverage equal to the then outstanding coverage of such Pool Insurance
Policy; provided, however, that, unless otherwise provided in the related
Prospectus Supplement, if the cost of the replacement policy is greater than the
cost of such Pool Insurance Policy, the coverage of the replacement policy may
be reduced to a level such that its premium rate does not exceed the premium
rate on such Pool Insurance Policy. However, in the event that the Pool Insurer
ceases to be a Qualified Insurer solely because it ceases to be approved as an
insurer by FHLMC, FNMA, or any successor entity, the Master Servicer will
review, or cause to be reviewed, the financial condition of the Pool Insurer
with a view towards determining whether recoveries under the Pool Insurance
Policy are jeopardized for reasons related to the financial condition of the
Pool Insurer. If the Master Servicer determines that recoveries are so
jeopardized, it will exercise its best reasonable efforts to obtain from another
Qualified Insurer a replacement policy as described above, subject to the same
cost limitation.
 
     Because each Pool Insurance Policy will require that the property subject
to a defaulted Residential Loan be restored to its original condition prior to
claiming against the Pool Insurer, such policy will not provide coverage against
hazard losses. As set forth above, the Primary Hazard Insurance Policies
covering the Residential Loans typically exclude from coverage physical damage
resulting from a number of causes and, even when the damage is covered, may
afford recoveries that are significantly less than full replacement cost of such
losses. Further, a special hazard insurance policy will not cover all risks, and
the coverage thereunder will be limited in amount. Certain hazard risks will, as
a result, be uninsured and will therefore be borne by the Securityholders.
 
SPECIAL HAZARD INSURANCE POLICIES
 
     If so specified in the Prospectus Supplement with respect to a Series of
Securities, the Master Servicer will obtain a special hazard insurance policy
for such Series, issued by the insurer specified in such Prospectus Supplement
(the "Special Hazard Insurer") covering any Special Hazard Amount (as defined
below). The Master Servicer will be obligated to exercise its best reasonable
efforts to keep or cause to be kept a special hazard insurance policy in full
force and effect, unless coverage thereunder has been exhausted through payment
of claims; provided, however, that the Master Servicer will be under no
obligation to maintain such policy in the event that a Pool Insurance Policy
covering such Series is no longer in effect or if otherwise provided in the
related Prospectus Supplement. The Master Servicer will be obligated to pay the
premiums on each special hazard insurance policy on a timely basis unless, as
described in the related Prospectus Supplement, payment of such premiums is
otherwise provided for. Claims under each special hazard insurance policy will
generally be limited to (i) a percentage set forth in the Prospectus Supplement
(expected to be not greater than 1%) of the
 
                                       68
<PAGE>
aggregate principal balance as of the Cut-off Date of the Residential Loans
comprising the related Trust Fund, (ii) twice the unpaid principal balance as of
the Cut-off Date of the largest Residential Loan in the Trust Fund, or
(iii) the greatest aggregate principal balance of Residential Loans secured by
Residential Properties located in any one California postal zip code area,
whichever is the greatest (the "Special Hazard Amount").
 
     As more specifically provided in the related Prospectus Supplement, each
special hazard insurance policy will, subject to limitations of the kind
described below, typically protect holders of Securities of the related Series
from (i) loss by reason of damage to Residential Properties caused by certain
hazards (including earthquakes and mudflows) not insured against under the
Primary Hazard Insurance Policies or a flood insurance policy if the property is
in a federally designated flood area and (ii) loss from partial damage caused by
reason of the application of the co-insurance clause contained in the Primary
Hazard Insurance Policies. Special hazard insurance policies will typically not
cover losses such as those occasioned by normal wear and tear, war, civil
insurrection, certain governmental actions, errors in design, faulty workmanship
or materials (except under certain circumstances), nuclear or chemical reaction
or contamination, flood (if the property is located in a federally designated
flood area) and certain other risks.
 
     Subject to the foregoing limitations, each special hazard insurance policy
will typically provide that, when there has been damage to property securing a
defaulted Residential Loan acquired by the insured and to the extent the damage
is not covered by the related Primary Hazard Insurance Policy or flood insurance
policy, the insurer will pay the lesser of (i) the cost of repair to the
property and (ii) upon transfer of the property to the insurer, the unpaid
principal balance of such Residential Loan at the time of acquisition of the
property by foreclosure, deed in lieu of foreclosure or repossession, plus
accrued interest at the Interest Rate to the date of claim settlement and
certain expenses incurred by or on behalf of the Master Servicer with respect to
the property. The amount of coverage under the special hazard insurance policy
will be reduced by the sum of (a) the unpaid principal balance plus accrued
interest and certain expenses paid by the insurer, less any net proceeds
realized by the insurer from the sale of the property, plus (b) any amount paid
as the cost of repair of the property.
 
     Typically, restoration of the property with the proceeds described under
clause (i) of the immediately preceding paragraph will satisfy the condition
under a Pool Insurance Policy that the property be restored before a claim
thereunder may be validly presented with respect to the defaulted Residential
Loan secured by such property. The payment described under clause (ii) of the
immediately preceding paragraph will render unnecessary presentation of a claim
in respect of such Residential Loan under a Pool Insurance Policy. Therefore, so
long as the Pool Insurance Policy remains in effect, the payment by the insurer
of either of the above alternative amounts will not affect the total insurance
proceeds paid to Securityholders, but will affect the relative amounts of
coverage remaining under any special hazard insurance policy and any Pool
Insurance Policy.
 
     The sale of a Residential Property must typically be approved by the
Special Hazard Insurer under any special hazard insurance policy and funds
received by the insured in excess of the unpaid principal balance of the
Residential Loan plus interest thereon to the date of sale plus certain expenses
incurred by or on behalf of the Master Servicer with respect to the property
(not to exceed the amount actually paid by the Special Hazard Insurer) must be
refunded to such Special Hazard Insurer and, to that extent, coverage under the
special hazard insurance policy will be restored. If aggregate claim payments
under a special hazard insurance policy reach the policy limit, coverage
thereunder will be exhausted and any further losses will be borne by the
Securityholders.
 
     A claim under a special hazard insurance policy generally must be filed
within a specified number of days (typically, 60 days) after the insured has
acquired good and merchantable title to the property, and a claim payment is
generally payable within a specified number of days (typically, 30 days) after a
claim is accepted by the Special Hazard Insurer. Special hazard insurance
policies generally provide that no claim may be paid unless Primary Hazard
Insurance Policy premiums, flood insurance premiums (if the property is located
in a federally designated flood area) and, as approved by the Special Hazard
Insurer, real estate property taxes (if applicable), property protection and
preservation expenses and foreclosure costs have been paid by or on behalf of
the insured, and unless the insured has maintained the Primary Hazard Insurance
Policy and, if the property is located in a federally designated flood area,
flood insurance, as required by the special hazard insurance policy.
 
     If a special hazard insurance policy is canceled or terminated for any
reason (other than the exhaustion of total policy coverage), the Master Servicer
will be obligated to use its best reasonable efforts to obtain or cause to be
obtained from another insurer a replacement policy comparable to such special
hazard insurance policy with a total coverage that is equal to the then existing
coverage of such special hazard insurance policy; provided,
 
                                       69
<PAGE>
however, that, unless otherwise provided in the related Prospectus Supplement,
if the cost of the replacement policy is greater than the cost of such special
hazard insurance policy, the coverage of the replacement policy may be reduced
to a level such that its premium rate does not exceed the premium rate on such
special hazard insurance policy.
 
     Since each special hazard insurance policy is designed to permit full
recoveries under a Pool Insurance Policy in circumstances in which such
recoveries would otherwise be unavailable because property has been damaged by a
cause not insured against by a Primary Hazard Insurance Policy and thus would
not be restored, each Pooling and Servicing Agreement will provide that, if the
related Pool Insurance Policy shall have lapsed or terminated or been exhausted
through payment of claims, the Master Servicer will be under no further
obligation to maintain the special hazard insurance policy.
 
BANKRUPTCY BONDS
 
     If so specified in the Prospectus Supplement with respect to a Series of
Securities, the Master Servicer will obtain a Bankruptcy Bond for such Series.
The obligor on, and the amount of coverage of, any such Bankruptcy Bond will be
set forth in the related Prospectus Supplement. The Master Servicer will
exercise its best reasonable efforts to maintain or cause to be maintained the
Bankruptcy Bond in full force and effect, unless coverage thereunder has been
exhausted through payment of claims. The Master Servicer will pay or cause to be
paid the premiums for each Bankruptcy Bond on a timely basis, unless, as
described in the Prospectus Supplement, payment of such premiums is otherwise
provided for. Subject to the limit of the dollar amount of coverage provided,
each Bankruptcy Bond will cover certain losses resulting from an extension of
the maturity of a Residential Loan, or a reduction by the bankruptcy court of
the principal balance of or the Interest Rate on a Residential Loan, and the
unpaid interest on the amount of a principal reduction during the pendency of a
proceeding under the United States Bankruptcy Code, 11 U.S.C. Sections 101 et
seq. (the "Bankruptcy Code"). See "Certain Legal Aspects of Residential
Loans--Foreclosure on Mortgages" and "--Repossession with respect to
Manufactured Housing Contracts."
 
RESERVE FUNDS
 
     If so provided in the related Prospectus Supplement, the Depositor will
deposit or cause to be deposited in an account (a "Reserve Fund") any
combination of cash, one or more irrevocable letters of credit or one or more
Permitted Instruments in specified amounts, or any other instrument satisfactory
to the Rating Agency or Agencies, which will be applied and maintained in the
manner and under the conditions specified in such Prospectus Supplement. In the
alternative or in addition to such deposit, to the extent described in the
related Prospectus Supplement, a Reserve Fund may be funded through application
of a portion of the interest payment on each Mortgage Loan or of all or a
portion of amounts otherwise payable on the Subordinate Securities. Amounts in a
Reserve Fund may be distributed to Securityholders, or applied to reimburse the
Master Servicer for outstanding Advances, or may be used for other purposes, in
the manner and to the extent specified in the related Prospectus Supplement.
Unless otherwise provided in the related Prospectus Supplement, any such Reserve
Fund will not be deemed to be part of the related Trust Fund.
 
     Amounts deposited in any Reserve Fund for a Series will be invested in
Permitted Instruments by, or at the direction of, the Master Servicer or any
other person named in the related Prospectus Supplement.
 
CROSS-SUPPORT PROVISIONS
 
     If so provided in the related Prospectus Supplement, the Residential Loans
for a Series of Securities may be divided into separate groups, each supporting
a separate class or classes of Securities of a Series, and credit support may be
provided by cross-support provisions requiring that distributions be made on
Securities evidencing interests in one group of Mortgage Loans prior to
distributions on Securities evidencing interests in a different group of
Mortgage Loans within the Trust Fund. The Prospectus Supplement for a Series
that includes a cross-support provision will describe the manner and conditions
for applying such provisions.
 
     The coverage provided by one or more forms of credit support may apply
concurrently to two or more related Trust Funds. If applicable, the related
Prospectus Supplement will identify the Trust Funds to which such credit support
relates and the manner of determining the amount of the coverage provided
thereby and of the application of such coverage to the identified Trust Funds.
 
                                       70
<PAGE>
LETTER OF CREDIT
 
     If so provided in the Prospectus Supplement for a Series of Securities, the
Residential Loans in the related Trust Fund will be covered by one or more
letters of credit, issued by a bank or financial institution specified in such
Prospectus Supplement (the "L/C Bank"). Under a letter of credit, the L/C Bank
will be obligated to honor draws 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
Residential Loans on the related Cut-off Date or one or more classes of
Securities. If so specified in the related Prospectus Supplement, the letter of
credit may permit draws in the event of only certain types of losses. The amount
available under the letter of credit will, in all cases, be reduced to the
extent of the unreimbursed payments thereunder.
 
INSURANCE POLICIES AND SURETY BONDS
 
     If so provided in the Prospectus Supplement for a Series of Certificates,
one or more classes of Securities of such Series 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.
 
EXCESS SPREAD
 
     If so provided in the Prospectus Supplement for a Series of Securities, a
portion of the interest payment on each Mortgage Loan may be applied to reduce
the principal balance of one or more classes of Securities to provide or
maintain a cushion against losses on the related Residential Loans.
 
                   CERTAIN LEGAL ASPECTS OF RESIDENTIAL LOANS
 
     The following discussion contains general summaries of certain legal
aspects of loans secured by residential properties. Because such legal aspects
are governed by applicable state law (which laws may differ substantially), the
summaries do not purport to be complete nor to reflect the laws of any
particular state, nor to encompass the laws of all states in which the security
for the Residential Loans is situated. The summaries are qualified in their
entirety by reference to the applicable federal and state laws governing the
Residential Loans. In this regard, the following discussion does not fully
reflect federal regulations with respect to FHA Loans and VA Loans. See "The
Trust Funds--Residential Loans" and "Description of Primary Insurance
Coverage--FHA Insurance and VA Guarantees."
 
GENERAL
 
     All of the Residential Loans, except as described below, are loans to
homeowners and all of the Mortgage Loans and Multifamily Loans are evidenced by
notes or bonds and secured by instruments which may be mortgages, deeds of
trust, security deeds or deeds to secure debt, depending upon the type of
security instrument customary to grant a security interest in real property in
the state in which the Residential Property is located. If specified in the
Prospectus Supplement relating to a Series of Securities, a Trust Fund may also
contain (i) Home Improvement Contracts evidenced by promissory notes, which may
be secured by an interest in the related Mortgaged Property, (ii) Cooperative
Loans evidenced by promissory notes secured by security interests in shares
issued by private, cooperative housing corporations and in the related
proprietary leases or occupancy agreements granting exclusive rights to occupy
specific dwelling units in the related buildings or (iii) Manufactured Housing
Contracts evidencing both (a) the obligation of the obligor to repay the loan
evidenced thereby and (b) the grant of a security interest in the related
Manufactured Home or with respect to Land Contracts, a lien on the real estate
(the "Mortgaged Property") to which the related Manufactured Homes are deemed to
be affixed, and including in some cases a security interest in the related
Manufactured Home, to secure repayment of such loan. Unless otherwise specified
in the Prospectus Supplement, any of the foregoing types of encumbrance will
create a lien upon, or grant a title interest in, the subject property, the
priority of which will depend on the terms of the particular security
instrument, the knowledge of the parties to such instruments, as well as the
order of recordation or filing of the instrument in the appropriate public
office. Such a lien is generally not prior to the lien for real estate taxes and
assessments and other charges imposed under governmental police powers.
 
                                       71
<PAGE>
MORTGAGE LOANS
 
     The Mortgage Loans and Multifamily Loans will be secured by either
mortgages, deeds of trust, security deeds or deeds to secure debt depending upon
the type of security instrument customary to grant a security interest according
to the prevailing practice in the state in which the property subject to a
Mortgage Loan or Multifamily Loan is located. Any of the foregoing types of
encumbrance creates a lien upon or conveys title to the real property encumbered
by such instrument and represents the security for the repayment of an
obligation that is customarily evidenced by a promissory note. Such a lien is
generally not prior to the lien for real estate taxes and assessments and other
charges imposed under governmental police powers. Priority with respect to these
security instruments depends on their terms and generally on the order of
recording with the applicable state, county or municipal office. There are two
parties to a mortgage, the mortgagor, who is the borrower and usually the owner
of the subject property or the land trustee (as described below), and the
mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. (In the case of a
land trust, title to the property is held by a land trustee under a land trust
agreement, while the owner is the beneficiary of the land trust; at origination
of a mortgage loan, the borrower executes a separate undertaking to make
payments on the mortgage note.) Although a deed of trust is similar to a
mortgage, a deed of trust normally has three parties, the trustor (similar to a
mortgagor), who is the owner of the subject property and may or may not be the
borrower, the beneficiary (similar to a mortgagee), who is the lender, and the
trustee, a third-party grantee. Under a deed of trust, the trustor grants the
property, irrevocably until the debt is paid, in trust, generally with a power
of sale, to the trustee to secure payment of the obligation. A 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 mortgagee's authority under a mortgage and the
trustee's authority under a deed of trust, security deed or deed to secure debt
are governed by the law of the state in which the real property is located, the
express provisions of the mortgage, deed of trust, security deed or deed to
secure debt and, in some cases, with respect to deeds of trust, the directions
of the beneficiary.
 
COOPERATIVE LOANS
 
     The Cooperative owns all the real property or some interest therein
sufficient to permit it to own the building and all separate dwelling units
therein. The Cooperative is directly responsible for property management and, in
most cases, payment of real estate taxes, other governmental impositions and
hazard and liability insurance. If there is a blanket mortgage on the
cooperative apartment building and/or underlying land, as is generally the case,
or an underlying lease of the land, as is the case in some instances, the
Cooperative, as mortgagor, or lessee, as the case may be, is also responsible
for meeting these blanket mortgage or rental obligations. A blanket mortgage is
ordinarily incurred by the Cooperative in connection with either the
construction or purchase of the Cooperative's apartment building or the
obtaining of capital by the Cooperative. The interests of the occupants under
proprietary leases or occupancy agreements as to which the Cooperative is the
landlord are generally subordinate to the interests of the holder of the blanket
mortgage and to the interest of the holder of a land lease. If the Cooperative
is unable to meet the payment obligations (i) arising under its blanket
mortgage, the mortgagee holding the blanket mortgage could foreclose on that
mortgage and terminate all subordinate proprietary leases and occupancy
agreements or (ii) arising under its land lease, the holder of the landlord's
interest under the land lease could terminate it and all subordinate proprietary
leases and occupancy agreements. Also, a blanket mortgage on a Cooperative may
provide financing in the form of a mortgage that does not fully amortize, with a
significant portion of principal being due in one final payment at final
maturity. The inability of the Cooperative to refinance such a mortgage and its
consequent inability to make such final payment could lead to foreclosure by the
mortgagee. Similarly, a land lease has an expiration date and the inability of
the Cooperative to extend its term or, in the alternative, to purchase the land
could lead to termination of the Cooperative's interest in the property and
termination of all proprietary leases and occupancy agreements. In either event,
foreclosure by the holder of the blanket mortgage or the termination of the
underlying lease could eliminate or significantly diminish the value of any
collateral held by the lender that financed the purchase by an individual
tenant-stockholder of Cooperative shares or, in the case of the Trust Fund, the
collateral securing the Cooperative Loans.
 
                                       72
<PAGE>
     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 occupancy rights is financed through
a Cooperative share loan evidenced by a promissory note and secured by an
assignment of and a security interest in the occupancy agreement or proprietary
lease and a security interest in the related Cooperative shares. The lender
generally takes possession of the share certificate and a counterpart of the
proprietary lease or occupancy agreement and a financing statement covering the
proprietary lease or occupancy agreement and the Cooperative shares is filed in
the appropriate state and local offices to perfect the lender's interest in its
collateral. Subject to the limitations discussed below, upon default of the
tenant-stockholder, the lender may sue for judgment on the promissory note,
dispose of the collateral at a public or private sale or otherwise proceed
against the collateral or tenant-stockholder as an individual as provided in the
security agreement covering the assignment of the proprietary lease or occupancy
agreement and the pledge of Cooperative shares. See "Foreclosure on Cooperative
Shares" below.
 
TAX ASPECTS OF COOPERATIVE OWNERSHIP
 
     In general, a "tenant-stockholder" (as defined in Section 216(b)(2) of the
Code) of a corporation that qualifies as a "cooperative housing corporation"
within the meaning of Section 216(b)(1) of the Code is allowed a deduction for
amounts paid or accrued within his taxable year to the corporation representing
his proportionate share of certain interest expenses and certain real estate
taxes allowable as a deduction under Section 216(a) of the Code to the
corporation under Sections 163 and 164 of the Code. In order for a corporation
to qualify under Section 216(b)(1) of the Code for its taxable year in which
such items are allowable as a deduction to the corporation, such section
requires, among other things, that at least 80% of the gross income of the
corporation be derived from its tenant-stockholders. By virtue of this
requirement, the status of a corporation for purposes of Section 216(b)(1) of
the Code must be determined on a year-to-year basis. Consequently, there can be
no assurance that cooperatives relating to the Cooperative Loans will qualify
under such section for any particular year. In the event that such a cooperative
fails to qualify for one or more years, the value of the collateral securing any
related Cooperative Loans could be significantly impaired because no deduction
would be allowable to tenant-stockholders under Section 216(a) of the Code with
respect to those years. In view of the significance of the tax benefits accorded
tenant-stockholders of a corporation that qualifies under Section 216(b)(1) of
the Code, the likelihood that such a failure would be permitted to continue over
a period of years appears remote.
 
MANUFACTURED HOUSING CONTRACTS OTHER THAN LAND CONTRACTS
 
     Under the laws of most states, manufactured housing constitutes personal
property and is subject to the motor vehicle registration laws of the state or
other jurisdiction in which the unit is located. In a few states, where
certificates of title are not required for the perfection of security interests
in manufactured homes, security interests are perfected by the filing of a
financing statement under Article 9 of the UCC which has been adopted by all
states. Such financing statements are effective for five years and must be
renewed at the end of each five years. The certificate of title laws adopted by
the majority of states provide that ownership of motor vehicles and manufactured
housing shall be evidenced by a certificate of title issued by the motor
vehicles department (or a similar entity) of such state. In the states which
have enacted certificate of title laws, a security interest in a unit of
manufactured housing, so long as it is not attached to land in so permanent a
fashion as to become a fixture, is generally perfected by the recording of such
interest on the certificate of title to the unit in the appropriate motor
vehicle registration office or by delivery of the required documents and payment
of a fee to such office, depending on state law.
 
     The Master Servicer will be required under the related Servicing Agreement
to effect such notation or delivery of the required documents and fees, and to
obtain possession of the certificate of title, as appropriate under the laws of
the state in which any Manufactured Home is registered. In the event the Master
Servicer fails, due to clerical errors or otherwise, to effect such notation or
delivery, or takes action under the wrong law (for example, under a motor
vehicle title statute rather than under the UCC), the Trustee likely will not
have a perfected security interest in the Manufactured Home securing a
Manufactured Housing Contract.
 
                                       73
<PAGE>
     As manufactured homes have become larger and often have been attached to
their sites without any apparent intention to move them, courts in many states
have held that manufactured homes may, under certain circumstances, become
subject to real estate title and recording laws. As a result, a security
interest in a manufactured home could be rendered subordinate to the interests
of other parties, including a trustee in bankruptcy claiming an interest in the
home under applicable state real estate law, notwithstanding compliance with the
requirements described above. In order to perfect a security interest in a
manufactured home under real estate laws, the holder of the security interest
must file either a "fixture filing" under the provisions of the UCC or a real
estate mortgage under the real estate laws of the state where the home is
located. These filings must be made in the real estate records office of the
county where the home is located. Generally, Manufactured Housing Contracts will
contain provisions prohibiting the obligor from permanently attaching the
Manufactured Home to its site. So long as the obligor does not violate this
agreement, a security interest in the Manufactured Home will be governed by the
certificate of title laws or the UCC, and the notation of the security interest
on the certificate of title or the filing of a UCC financing statement will be
effective to perfect the security interest in the Manufactured Home. If,
however, a Manufactured Home is permanently attached to its site, other parties,
including a trustee in bankruptcy, could obtain an interest in the Manufactured
Home which is prior to the security interest originally retained by the seller
and transferred to the Depositor.
 
     The Depositor will assign or cause to be assigned a security interest in
the Manufactured Homes to the Trustee, on behalf of the Securityholders. Unless
otherwise specified in the related Prospectus Supplement, neither the Depositor,
the Master Servicer nor the Trustee will amend the certificates of title to
identify the Trustee, on behalf of the Securityholders, as the new secured party
and, accordingly, the Depositor or the Unaffiliated Seller will continue to be
named as the secured party on the certificates of title relating to the
Manufactured Homes. In most states, such assignment is an effective conveyance
of such security interest without amendment of any lien noted on the related
certificate of title and the new secured party, therefore, succeeds to the
Depositor's rights as the secured party. However, in some states there exists a
risk that, in the absence of an amendment to the certificate of title, such
assignment of the security interest might not be held effective against
creditors of the Depositor or Unaffiliated Seller.
 
     In the absence of fraud, forgery or permanent affixation of the
Manufactured Home to its site by the Manufactured Home owner, or administrative
error by state recording officials, the notation of the lien of the Depositor on
the certificate of title or delivery of the required documents and fees or, in
states where a security interest in manufactured homes is perfected pursuant to
Article 9 of the UCC, the filing of a financing statement (and continuation
statements before the end of each five year period) will be sufficient to
protect the Trustee against the rights of subsequent purchasers of a
Manufactured Home or subsequent lenders who take a security interest in the
Manufactured Home. If there are any Manufactured Homes as to which the Depositor
has failed to perfect or cause to be perfected the security interest assigned to
the Trust Fund, such security interest would be subordinate to, among others,
subsequent purchasers for value of Manufactured Homes, holders of perfected
security interests, and a trustee in bankruptcy. There also exists a risk in not
identifying the Trustee, on behalf of the Securityholders as the new secured
party on the certificate of title that, through fraud or negligence, the
security interest of the Trustee could be released.
 
     In the event that the owner of a Manufactured Home moves it to a state
other than the state in which such Manufactured Home initially is registered,
under the laws of most states the perfected security interest in the
Manufactured Home would continue for four months after such relocation and
thereafter until the owner re-registers the Manufactured Home in such state. If
the owner were to relocate a Manufactured Home to another state and re-register
the Manufactured Home in such state, and if the Depositor did not take steps to
re-perfect its security interest in such state, the security interest in the
Manufactured Home would cease to be perfected. A majority of states generally
require surrender of a certificate of title to re-register a Manufactured Home;
accordingly, if the Depositor holds the certificate of title to such
Manufactured Home, it must surrender possession of such certificate. In the case
of Manufactured Homes registered in states which provide for notation of lien,
the Depositor would receive notice of surrender if the security interest in the
Manufactured Home is noted on the certificate of title. Accordingly, the
Depositor could re-perfect its security interest in the Manufactured Home in the
state of relocation. In states which do not require a certificate of title for
registration of a manufactured home, re-registration could defeat perfection.
Similarly, when an obligor under a manufactured housing conditional sales
contract sells a manufactured home, the obligee must surrender possession of the
certificate of title or it will receive notice as a result of its lien noted
thereon and accordingly will have an
 
                                       74
<PAGE>
opportunity to require satisfaction of the related manufactured housing
conditional sales contract before release of the lien. Under the Servicing
Agreement, the Master Servicer will be obligated to take such steps, at the
Master Servicer's expense, as are necessary to maintain perfection of security
interests in the Manufactured Homes.
 
     Under the laws of most states, statutory liens, such as liens for repairs
performed on a Manufactured Home and liens for personal property taxes take
priority even over a perfected security interest. In addition, certain liens
arising as a matter of federal law, such as federal tax liens, also take
priority over a perfected security interest. The Depositor will obtain the
representation of the Unaffiliated Seller that it has no knowledge of any such
liens with respect to any Manufactured Home securing a Contract. However, such
liens could arise at any time during the term of a Contract. No notice will be
given to the Trustee or Securityholders in the event such a lien arises.
 
FORECLOSURE ON MORTGAGES
 
     Foreclosure of a mortgage is generally accomplished by judicial action.
Generally, the action is initiated by the service of legal pleadings upon all
parties having an interest of record in the real property. Delays in completion
of the foreclosure may occasionally result from difficulties in locating
necessary parties defendant. When the mortgagee's right to foreclose is
contested, the legal proceedings necessary to resolve the issue can be time
consuming. After the completion of a judicial foreclosure, the court generally
issues a judgment of foreclosure and appoints a referee or other court officer
to conduct the sale of the property.
 
     An action to foreclose a mortgage is an action to recover the mortgage debt
by enforcing the mortgagee's rights under the mortgage in and to the mortgaged
property. It is regulated by statutes and rules and subject throughout to the
court's equitable powers. Generally, a mortgagor is bound by the terms of the
mortgage note and the mortgage as made and cannot be relieved from its own
default. However, since a foreclosure action is equitable in nature and is
addressed to a court of equity, the court may relieve a mortgagor of a default
and deny the mortgagee foreclosure on proof that the mortgagor's default was
neither willful nor in bad faith and that the mortgagee's action was such as to
establish a waiver, or fraud, bad faith, oppressive or unconscionable conduct as
to warrant a court of equity to refuse affirmative relief to the mortgagee.
Under certain circumstances a court of equity may relieve the mortgagor from an
entirely technical default where such default was not willful.
 
     A foreclosure action or sale pursuant to a power of sale is subject to most
of the delays and expenses of other lawsuits if defenses or counterclaims are
interposed, sometimes requiring up to several years to complete. Moreover, a
non-collusive, regularly conducted foreclosure sale or sale pursuant to a power
of sale may be challenged as a fraudulent conveyance, regardless of the parties'
intent, if a court determines that the sale was for less than fair consideration
and such sale occurred while the mortgagor was insolvent and within one year (or
within the state statute of limitations if the trustee in bankruptcy elects to
proceed under state fraudulent conveyance law) of the filing of bankruptcy.
Similarly, a suit against the debtor on the mortgage note may take several years
and, generally, is a remedy alternative to foreclosure, the mortgagee being
precluded from pursuing both at the same time. In some states, mortgages may
also be foreclosed by advertisement pursuant to a power of sale provided in the
mortgage. Foreclosure of a mortgage by advertisement is essentially similar to
foreclosure of a deed of trust by nonjudicial power of sale.
 
     Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust which authorizes
the trustee to sell the property upon default by the borrower under the terms of
the note or deed of trust. In some states, prior to such sale, the trustee must
record a notice of default and send a copy to the borrower-trustor and to any
person who has recorded a request for a copy of a notice of default and notice
of sale. In addition, in some states the trustee must provide notice to any
other individual having an interest in the real property, including any junior
lienholder. In some states, the trustor, borrower, or any person having a junior
encumbrance on the real estate, may, during a reinstatement period, cure the
default by paying the entire amount in arrears plus the costs and expenses
incurred in enforcing the obligation to the extent allowed by applicable law.
Generally, state law controls the amount of foreclosure expenses and costs,
including attorneys' fees, which may be recovered by a lender. Certain states
require that a notice of sale must be posted in a public place and, in most
states, published for a specific period of time in a specified manner prior to
the date of the trustee's sale. In addition, some state laws require that a copy
of the notice of sale be posted on the property, recorded and sent to all
parties having an interest in the real property. In certain states, foreclosure
under a deed of trust may also be accomplished by judicial action in the manner
provided for foreclosure of mortgages.
 
                                       75
<PAGE>
     In case of foreclosure under either a mortgage or a deed of trust, the sale
by the referee or other designated officer or by the trustee is generally a
public sale. However, because of the difficulty potential third party purchasers
at the sale might have in determining the exact status of title and because the
physical condition of the property may have deteriorated during the foreclosure
proceedings, it is uncommon for a third party to purchase the property at the
foreclosure sale. In some states, potential buyers may be further unwilling to
purchase a property at a foreclosure sale as a result of the 1980 decision of
the United States Court of Appeals for the Fifth Circuit in Durrett v.
Washington National Insurance Company. The court in Durrett held that even a
non-collusive, regularly conducted foreclosure sale was a fraudulent transfer
under section 67 of the former Bankruptcy Act (section 548 of the current
Bankruptcy Code) and, therefore, could be rescinded in favor of the bankrupt's
estate, if (i) the foreclosure sale was held while the debtor was insolvent and
not more than one year prior to the filing of the bankruptcy petition, and (ii)
the price paid for the foreclosed property did not represent "fair
consideration" ("reasonably equivalent value" under the Bankruptcy Code).
However, on May 23, 1994, Durrett was effectively overruled by the United States
Supreme Court in BFP v. Resolution Trust Corporation, as Receiver for Imperial
Federal Savings and Loan Association, et al., in which the Court held that "
'reasonably equivalent value', for foreclosed property, is the price in face
received at the foreclosure sale, so long as all the requirements of the State's
foreclosure law have been complied with." The Supreme Court decision, however,
may not be controlling as to whether a non-collusive, regularly conducted
foreclosure can be avoided as a fraudulent conveyance under applicable state
law, if a court determines that the sale was for less than "fair consideration"
under applicable state law. For these reasons, it is common for the lender to
purchase the property from the trustee or referee for an amount equal to the
principal amount of the mortgage or deed of trust plus accrued and unpaid
interest and the expenses of foreclosure. Generally, state law controls the
amount of foreclosure costs and expenses, including attorneys' and trustee's
fees, which may be recovered by a lender. In some states there is a statutory
minimum purchase price which the lender may offer for the property. Thereafter,
subject to the right of the borrower in some states to remain in possession
during the redemption period, the lender will assume ownership of the mortgaged
property and, therefore, the burdens of ownership, including obtaining casualty
insurance, paying taxes and making such repairs at its own expense as are
necessary to render the property suitable for sale. 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 insurance proceeds, if any.
 
     A junior mortgagee may not foreclose on the property securing a junior
mortgage unless it forecloses subject to the senior mortgages, in which case it
must either pay the entire amount due on the senior mortgages to the senior
mortgagees prior to or at the time of the foreclosure sale or undertake the
obligation to make payments on the senior mortgages in the event the mortgagor
is in default thereunder, in either event adding the amounts expended to the
balance due on the junior loan, and may be subrogated to the rights of the
senior mortgagees. In addition, in the event that the foreclosure of a junior
mortgage triggers the enforcement of a "due-on-sale" clause, the junior
mortgagee may be required to pay the full amount of the senior mortgages to the
senior mortgagees. Accordingly, with respect to those Mortgage Loans which are
junior mortgage loans, if the lender purchases the property, the lender's title
will be subject to all senior liens and claims and certain governmental liens.
The proceeds received by the referee or trustee from the sale are applied first
to the costs, fees and expenses of sale and then in satisfaction of the
indebtedness secured by the mortgage or deed of trust under which the sale was
conducted. Any remaining proceeds are generally payable to the holders of junior
mortgages or deeds of trust and other liens and claims in order of their
priority, whether or not the borrower is in default. Any additional proceeds are
generally payable to the mortgagor or trustor. The payment of the proceeds to
the holders of junior mortgages may occur in the foreclosure action of the
senior mortgagee or may require the institution of separate legal proceedings.
 
     In foreclosure, courts have imposed general equitable principles. The
equitable principles are generally designed to relieve the borrower from the
legal effect of his defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have substituted their judgment for
the lender's judgment and have required that lenders reinstate loans or recast
payment schedules in order to accommodate borrowers who are suffering from
temporary financial disability. In other cases, courts have limited the right of
a lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower's failure to
 
                                       76
<PAGE>
adequately maintain the property or the borrower's execution of a second
mortgage or deed of trust affecting the property. Finally, some courts have been
faced with the issue of whether or not federal or state constitutional
provisions reflecting due process concerns for adequate notice require that
borrowers under deeds of trust or mortgages receive notices in addition to the
statutorily-prescribed minimums. For the most part, these cases have upheld the
notice provisions as being reasonable or have found that the sale by a trustee
under a deed of trust, or under a mortgage having a power of sale, does not
involve sufficient state action to afford constitutional protections to the
borrower.
 
     In addition, certain states impose a statutory lien for associated costs on
property that is the subject of a cleanup action by the state on account of
hazardous wastes or hazardous substances released or disposed of on the
property. Such a lien may have priority over all subsequent liens on the
property and, in certain of these states, will have priority over prior recorded
liens, including the lien of a mortgage. In addition, under federal
environmental legislation and possibly under state law in a number of states, a
secured party that takes a deed in lieu of foreclosure or acquires a mortgaged
property at a foreclosure sale may be liable for the costs of cleaning up a
contaminated site. Although such costs could be substantial, it is unclear
whether they would be imposed on a secured lender on residential properties. In
the event that title to a Residential Property was acquired on behalf of
Securityholders and cleanup costs were incurred in respect of the Residential
Property, such Securityholders might realize a loss if such costs were required
to be paid by the related Trust Fund.
 
FORECLOSURE ON COOPERATIVE SHARES
 
     The Cooperative shares and proprietary lease or occupancy agreement owned
by the tenant-stockholder and pledged to the lender are, in almost all cases,
subject to restrictions on transfer as set forth in the Cooperative's
Certificate of Incorporation and By-laws, as well as in the proprietary lease or
occupancy agreement, and may be canceled by the Cooperative, even while pledged,
for failure by the tenant-stockholder to pay rent or other obligations or
charges owed by such tenant-stockholder, including mechanics' liens against the
Cooperative apartment building incurred by such tenant-stockholder. Commonly,
rent and other obligations and charges arising under a proprietary lease or
occupancy agreement which are owed to the cooperative are made liens upon the
shares to which the proprietary lease or occupancy agreement relates. In
addition, the proprietary lease or occupancy agreement generally permits the
Cooperative to terminate such lease or agreement in the event the
tenant-stockholder 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, together with any lender protection
provisions contained in the proprietary lease, establishes the rights and
obligations of both parties in the event of a default by 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 notice of and an opportunity
to cure the default. The recognition agreement typically provides that if the
proprietary lease or occupancy agreement is terminated, the Cooperative will
recognize the lender's lien against proceeds from a sale of the Cooperative
apartment, subject, however, to the Cooperative's right to sums due under such
proprietary lease or occupancy agreement or which have become liens on the
shares relating to the proprietary lease or occupancy agreement. The total
amount owed to the Cooperative by the tenant-stockholder, which the lender
generally cannot restrict and does not monitor, could reduce the value of the
collateral below the outstanding principal balance of the Cooperative Loan and
accrued and unpaid interest thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan, the lender must obtain the approval or consent of the
Cooperative as required by the proprietary lease before transferring the
Cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     Foreclosure on the Cooperative shares is accomplished by a sale in
accordance with the provisions of Article 9 of the UCC and the security
agreement relating to those shares. Article 9 of the UCC requires that a sale be
conducted in a "commercially reasonable" manner. Whether a sale has been
conducted in a "commercially reasonable" manner will depend on the facts in each
case. In determining commercial reasonableness, a court
 
                                       77
<PAGE>
will look to the notice given the debtor and the method, manner, time, place and
terms of the sale. Generally, a sale conducted according to the usual practice
of similar parties selling similar collateral will be considered reasonably
conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the Cooperative corporation to receive sums due under
the proprietary lease or occupancy agreement. If there are proceeds remaining,
the lender must account to the tenant-stockholder for the surplus. Conversely,
if a portion of the indebtedness remains unpaid, the tenant-stockholder is
generally responsible for the deficiency. See "Anti-Deficiency Legislation and
Other Limitations on Lenders" below.
 
REPOSSESSION WITH RESPECT TO MANUFACTURED HOUSING CONTRACTS THAT ARE NOT LAND
CONTRACTS
 
     Repossession of manufactured housing is governed by state law. So long as a
manufactured home has not become so attached to real estate that it would be
treated as a part of the real estate under the law of the state where it is
located, repossession of such home in the event of a default by the obligor will
generally be governed by the UCC. Article 9 of the UCC provides the statutory
framework for the repossession of manufactured housing. While the UCC as adopted
by the various states may vary in certain small particulars, the general
repossession procedure established by the UCC is as follows:
 
          (i) Except in those few states where the debtor must receive notice of
     his right to cure his default (typically 30 days to bring the account
     current), repossession can commence immediately upon default without prior
     notice. Repossession may be effected either through self-help (peaceable
     retaking without court order), voluntary repossession or through judicial
     process (repossession pursuant to court-issued writ of replevin). The
     self-help and/or voluntary repossession methods are more commonly employed,
     and are accomplished simply by retaking possession of the manufactured
     home. In cases where the debtor objects or raises a defense to
     repossession, a court order must be obtained from the appropriate state
     court, and the manufactured home must then be repossessed in accordance
     with that order. Whether the method employed is self-help, voluntary
     repossession or judicial repossession, the repossession can be accomplished
     either by an actual physical removal of the manufactured home to a secure
     location for refurbishment and resale or by removing the occupants and
     their belongings from the manufactured home and maintaining possession of
     the manufactured home on the location where the occupants were residing.
     Various factors may affect whether the manufactured home is physically
     removed or left on location, such as the nature and term of the lease of
     the site on which it is located and the condition of the unit. In many
     cases, leaving the manufactured home on location is preferable, in the
     event that the home is already set up, because the expenses of retaking and
     redelivery will be saved. However, in those cases where the home is left on
     location, expenses for site rentals will usually be incurred.
 
          (ii) Once repossession has been achieved, preparation for the
     subsequent disposition of the manufactured home can commence. The
     disposition may be by public or private sale, upon notice to the debtor,
     and the method, manner, time, place and terms of the sale must be
     commercially reasonable. The UCC and consumer protection laws in most
     states place restrictions on repossession sales, including requiring prior
     notice to the debtor.
 
          (iii) Sale proceeds are to be applied first to repossession expenses
     (expenses incurred in retaking, storage, preparing for sale to include
     refurbishing costs and selling) and then to satisfaction of the
     indebtedness. While some states impose prohibitions or limitations on
     deficiency judgments if the net proceeds from resale do not cover the full
     amount of the indebtedness, the deficiency may be sought from the debtor in
     the form of a deficiency judgment in those states which do not prohibit or
     limit such judgments. The deficiency judgment is a personal judgment
     against the debtor for the shortfall. Occasionally, after resale of a
     manufactured home and payment of all expenses and indebtedness, there is a
     surplus of funds. In that case, the UCC requires the party suing for the
     deficiency judgment to remit the surplus to the debtor. Because the
     defaulting owner of a manufactured home generally has very little capital
     or income available following repossession, a deficiency judgment may not
     be sought in many cases or, if obtained, will be settled at a significant
     discount in light of the defaulting owner's strained financial condition.
 
                                       78

RIGHTS OF REDEMPTION WITH RESPECT TO RESIDENTIAL PROPERTIES
 
     The purposes of a foreclosure action are to enable the mortgagee to realize
upon its security and to bar the mortgagor, and all persons who have an interest
in the property which is subordinate to the foreclosing mortgagee, from
exercising their "equity of redemption." The doctrine of equity of redemption
provides that, until the property covered by a mortgage has been sold in
accordance with a properly conducted foreclosure and foreclosure sale, parties
having an interest which is subordinate to that of the foreclosing mortgagee may
redeem the property by paying the entire debt with interest. In addition, in
some states, when a foreclosure action has been commenced, the redeeming party
must pay certain costs of such action. Parties having an equity of redemption
must generally be made parties and duly summoned to the foreclosure action in
order for their equity of redemption to be barred.
 
     Equity of redemption which is a non-statutory right that must be exercised
prior to foreclosure sale, should be distinguished from statutory rights of
redemption. In some states, after sale pursuant to a deed of trust or
foreclosure of a mortgage, the trustor or mortgagor and certain foreclosed
junior lienors are given a statutory period in which to redeem the property from
the foreclosure sale. In some states, redemption may occur only upon payment of
the foreclosure sales price, accrued interest and expenses of foreclosure. In
other states, redemption may be authorized if the former borrower pays only a
portion of the sums due. The effect of a statutory right of redemption is to
diminish the ability of the lender to sell the foreclosed property. The exercise
of a right of redemption would defeat the title of any purchaser subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
a right of redemption is to force the lender to retain the property and pay the
expenses of ownership and maintenance of the property until the redemption
period has expired. In some states, there is no right to redeem property after a
trustee's sale under a deed of trust.
 
NOTICE OF SALE; REDEMPTION RIGHTS WITH RESPECT TO MANUFACTURED HOMES
 
     While state laws do not usually require notice to be given debtors prior to
repossession, many states do require delivery of a notice of default and of the
debtor's right to cure defaults before repossession. The law in most states also
requires that the debtor be given notice of sale prior to the resale of the home
so that the owner may redeem at or before resale. In addition, the sale must
comply with the requirements, including the notice requirements, of the UCC.
 
ANTI-DEFICIENCY LEGISLATION, BANKRUPTCY LAWS AND OTHER LIMITATIONS ON LENDERS
 
Certain states have imposed statutory prohibitions which limit the remedies of a
beneficiary under a deed of trust or a mortgagee under a mortgage. In some
states, statutes limit the right of the beneficiary or mortgagee to obtain a
deficiency judgment against the borrower following foreclosure or sale under a
deed of trust. A deficiency judgment is a personal judgment against the former
borrower equal in most cases to the difference between the net amount realized
upon the public sale of the real property and the amount due to the lender.
Other statutes require the beneficiary or mortgagee to exhaust the security
afforded under a deed of trust or mortgage by foreclosure in an attempt to
satisfy the full debt before bringing a personal action against the borrower. In
certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security; however
in some of these states, the lender, following judgment on such personal action,
may be deemed to have elected a remedy and may be precluded from exercising
remedies with respect to the security. Consequently, the practical effect of the
election requirement, in those states permitting such election, is that lenders
will usually proceed against the security first rather than bringing a personal
action against the borrower. Finally, other statutory provisions limit any
deficiency judgment against the former borrower following a judicial sale to the
excess of the outstanding debt over the fair market value of the property at the
time of the public sale. The purpose of these statutes is generally to prevent a
beneficiary or a mortgagee from obtaining a large deficiency judgment against
the former borrower as a result of low or no bids at the judicial sale.
 
     In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the Bankruptcy Code and state
laws affording relief to debtors, may interfere with or affect the ability of a
secured mortgage lender to obtain payment of a mortgage loan, to realize upon
collateral and/or enforce a deficiency judgment. For example, under the
Bankruptcy Code, virtually all actions (including foreclosure actions and
deficiency judgment proceedings) are automatically stayed upon the filing of a
bankruptcy petition, and, usually, no interest or principal payments are made
during the course of the bankruptcy case. Foreclosure of
 
                                       79
<PAGE>
an interest in real property of a debtor in a case under the Bankruptcy Code can
typically occur only if the bankruptcy court vacates the stay; an action the
bankruptcy court may be reluctant to take, particularly if the debtor has the
prospect of restructuring his or her debts and the mortgage collateral is not
deteriorating in value. The delay and the consequences thereof caused by such
automatic stay can be significant. Also, under the Bankruptcy Code, the filing
of a petition in bankruptcy by or on behalf of a junior lienor (a subordinate
lender secured by a mortgage on the property) may stay the senior lender from
taking action to foreclose out such junior lien.
 
     A homeowner may file for relief under the Bankruptcy Code under any of
three different chapters of the Bankruptcy Code. Under Chapter 7, the assets of
the debtor are liquidated and a lender secured by a lien may "bid in" (i.e., bid
up to the amount of the debt) at the sale of the asset. (See "--Foreclosure on
Mortgages.") A homeowner may also file for relief under Chapter 11 of the
Bankruptcy Code and reorganize his or her debts through his or her
reorganization plan. Alternatively, a homeowner may file for relief under
Chapter 13 of the Bankruptcy Code and address his or her debts in a
rehabilitation plan. (Chapter 13 is often referred to as the "wage earner
chapter" or "consumer chapter" because most individuals seeking to restructure
their debts file for relief under Chapter 13 rather than under Chapter 11.)
 
     A reorganzation plan under Chapter 11 and a rehabilitation plan under
Chapter 13 of the Bankruptcy Code may each allow a debtor to cure a default with
respect to a mortgage loan on such debtor's residence by paying arrearages
within a reasonable time period and to deaccelerate and reinstate the original
mortgage loan payment schedule, even though the lender accelerated the loan and
a final judgment of foreclosure had been entered in state court (provided no
sale of the property had yet occurred) prior to the filing of the debtor's
petition under the Bankruptcy Code. Courts have approved Chapter 11 plans that
have allowed curing of defaults over a number of years. In certain
circumstances, defaults may be cured over a number of years even if the full
amount due under the original loan is never repaid, notwithstanding objection by
the mortgagee. Under a Chapter 13 plan, curing of defaults must be accomplished
within the five year maximum term permitted for repayment plans.
 
     Generally, a repayment plan filed in a case under Chapter 13 may not modify
the claim of a mortgage lender if the borrower elects to retain the property,
the property is the borrower's principal residence and the property is the
lender's only collateral. Notwithstanding the forgoing restrictions, if the last
payment on the original payment schedule of a mortgage loan secured only by the
debtor's principal residence is due before the final date for payment under such
debtor's Chapter 13 plan (which date could be up to five years after the debtor
emerges from bankruptcy), under a case recently decided by an intermediate
appellate court, the debtor's rehabilitation plan could modify the terms of the
loan by bifurcating an undersecured lender's claim into a secured and an
unsecured component in the same manner as if the debtor were a debtor in a case
under Chapter 11 (see the following paragraph). While this decision is contrary
to a prior decision of a more senior appellate court in another jurisdiction, it
is possible that the intermediate court's decision will become the accepted
interpretation in view of the language of the applicable statutory provision. If
this interpretation is adopted by a court considering the treatment in a Chapter
13 repayment plan of a home equity loan, the home equity loan could be
restructured as if the bankrupcy case were under Chapter 11 if the final payment
is due within five years of the debtor's emergence from bankruptcy.
 
     In a case under Chapter 11, provided certain substantive and procedural
safeguards are met, the amount and terms of a mortgage loan secured by property
of the debtor, including the debtor's principal residence, may be modified.
Under the Bankruptcy Code, the outstanding amount of a loan secured by the real
property may be reduced to the then-current value of the property as determined
by the court (with a corresponding partial reduction of the amount of the
lender's security interest) if the value is less than the amount due on the
loan, leaving the lender a general unsecured creditor for the difference between
such value of the collateral and the outstanding balance of the loan. A
borrower's unsecured indebtedness will typically be discharged in full upon
payment of a substantially reduced amount. Other modifications may include a
reduction in the amount of each scheduled payment, which reduction may result
from a reduction in the rate of interest and/or the alteration of the repayment
schedule (with or without affecting the unpaid principal balance of the loan),
and/or an extension (or reduction) of the final maturity date. State statutes
and general principles of equity may also provide a mortgagor with means to halt
a foreclosure proceeding or sale and to force a restructuring of a mortgage loan
on terms a lender would not otherwise accept. Because many of the Mortgage Loans
will have loan-to-value ratios in excess of 100% at origination (or such
loan-to-value ratios otherwise may exceed 100% in cases where the market value
 
                                       80
<PAGE>
declined subsequent to origination), a potentially significant portion of the
unpaid principal amount of the related Mortgage Loan would likely be treated as
unsecured indebtedness in a case under Chapter 11.
 
     In a bankruptcy or similar proceeding of a mortgagor, action may be taken
seeking the recovery, as a preferential transfer or on other grounds, of any
payments made by the mortgagor under the related mortgage loan. Payments on
long-term debt may be protected from recovery as preferences if they are
payments in the ordinary course of business made on debts incurred in the
ordinary course of business or if the value of the collateral exceeds the debt
at the time of payment. Whether any particular payment would be protected
depends upon the facts specific to a particular transaction.
 
     A trustee in bankruptcy, in some cases, may be entitled to collect its
costs and expenses in preserving or selling the mortgaged property ahead of
payment to the lender. In certain circumstances, subject to the court's
approval, a debtor in a case under Chapter 11 of the Bankruptcy Code may have
the power to grant liens senior to the lien of a mortgage. Moreover, the laws of
certain states also give priority to certain tax and mechanics liens over the
lien of a mortgage. Under the Bankruptcy Code, if the court finds that actions
of the mortgagee have been unreasonable and inequitable, the lien of the related
mortgage may be subordinated to the claims of unsecured creditors.
 
     Various proposals to amend the Bankruptcy Code in ways that could adversely
affect the value of the Mortgage Loans have been considered by Congress, and
more such proposed legislation may be considered in the future. No assurance can
be given that any particular proposal will or will not be enacted into law, or
that any provision so enacted will not differ materially from the proposals
described above.
 
     The Code provides priority to certain tax liens over the lien of the
mortgage. This may have the effect of delaying or interfering with the
enforcement of rights in respect of a defaulted Mortgage Loan. In addition,
substantive requirements are imposed upon mortgage lenders in connection with
the origination and the servicing of mortgage loans by numerous federal and some
state consumer protection laws. The laws include the federal Truth-in-Lending
Act, (and Regulation Z), Real Estate Settlement Procedures Act (and Regulation
X), Equal Credit Opportunity Act (and Regulation B), Fair Credit Billing Act,
Fair Credit Reporting Act, Fair Housing Act, Housing and Community Development
Act, Home Mortgage Disclosure Act, Federal Trade Commission Act, Fair Debt
Collection Practices Act, Uniform Consumer Credit Code, Consumer Credit
Protection Act, Riegle Act, and related statutes and regulations. These federal
laws impose specific statutory liabilities upon lenders who originate mortgage
loans and who fail to comply with the provisions of the law. In some cases, this
liability may affect assignees of the mortgage loans.
 
FOR COOPERATIVE LOANS
 
     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.
 
JUNIOR MORTGAGES
 
     Some of the Mortgage Loans, Multifamily Loans and Home Improvement
Contracts may be secured by junior mortgages or deeds of trust, which are junior
to senior mortgages or deeds of trust which are not part of the Trust Fund. The
rights of the Certificateholders as the holders of a junior deed of trust or a
junior mortgage are subordinate in lien priority and in payment priority to
those of the holder of the senior mortgage or deed of trust, including the prior
rights of the senior mortgagee or beneficiary to receive and apply hazard
insurance and condemnation proceeds and, upon default of the mortgagor, to cause
a foreclosure on the property. Upon completion of the foreclosure proceedings by
the holder of the senior mortgage or the sale pursuant to the deed of trust, the
junior mortgagee's or junior beneficiary's lien will be extinguished unless the
junior lienholder satisfies the defaulted senior loan or asserts its subordinate
interest in a property in foreclosure proceedings. See "--Foreclosure" herein.
 
     Furthermore, the terms of the junior mortgage or deed of trust are
subordinate to the terms of the senior mortgage or deed of trust. In the event
of a conflict between the terms of the senior mortgage or deed of trust and the
junior mortgage or deed of trust, the terms of the senior mortgage or deed of
trust will govern generally. Upon a failure of the mortgagor or trustor to
perform any of its obligations, the senior mortgagee or beneficiary, subject
 
                                       81
<PAGE>
to the terms of the senior mortgage or deed of trust, may have the right to
perform the obligation itself. Generally, all sums so expended by the mortgagee
or beneficiary become part of the indebtedness secured by the mortgage or deed
of trust. To the extent a senior mortgagee expends such sums, such sums will
generally have priority over all sums due under the junior mortgage.
 
CONSUMER PROTECTION LAWS WITH RESPECT TO HOME IMPROVEMENT AND MANUFACTURED
HOUSING CONTRACTS
 
     Numerous Federal and state consumer protection laws impose substantial
requirements upon creditors involved in consumer finance. These laws include the
federal Truth-in-Lending Act (and Regulation Z), Real Estate Settlement
Procedures Act (and Regulation X), Equal Credit Opportunity Act (and Regulation
B), Fair Credit Billing Act, Fair Credit Reporting Act, Fair Housing Act,
Housing and Community Development Act, Home Mortgage Disclosure Act, Federal
Trade Commission Act, Fair Debt Collection Practices Act, Uniform Consumer
Credit Code, Consumer Credit Protection Act, Riegle Act, and related statutes
and regulations. These laws can impose specific statutory liabilities upon
creditors who fail to comply with their provisions and may affect the
enforceability of the contract.
 
     Contracts often contain provisions obligating the obligor to pay late
charges if payments are not timely made. In certain cases, Federal and state law
may specifically limit the amount of late charges that may be collected. Unless
otherwise provided in the related Prospectus Supplement, under an Agreement,
late charges will be retained by the Master Servicer as additional servicing
compensation, and any inability to collect these amounts will not affect
payments to Certificateholders.
 
     Courts have imposed general equitable principles upon repossession and
litigation involving deficiency balances. These equitable principles are
generally designed to relieve a consumer from the legal consequences of a
default.
 
     In several cases, consumers have asserted that the remedies provided
secured parties under the UCC and related laws violate the due process
protections provided under the 14th Amendment to the Constitution of the United
States. For the most part, courts have upheld the notice provisions of the UCC
and related laws as reasonable or have found that the repossession and resale by
the creditor does not involve sufficient state action to afford constitutional
protection to consumers.
 
     The so-called "Holder-in-Due-Course" Rule of the Federal Trade Commission
(the "FTC Rule") has the effect (subject to any applicable limitations imposed
by the Riegle Act) of subjecting a seller (and certain related creditors and
their assignees (to the extent the liability of such parties is not limited by
the provisions of the Riegle Act)) in a consumer credit transaction and any
assignee of the creditor to all claims and defenses which the debtor in the
transaction could assert against the seller of the goods. Liability under the
FTC Rule is limited to the amounts paid by a debtor on the contract, and the
holder of the contract may also be unable to collect amounts still due
thereunder.
 
     Most of the Manufactured Housing Contracts and certain of the Home
Improvement Contracts in the Trust Fund will be subject to the requirements of
the FTC Rule. Accordingly, the Trustee, as holder of Manufactured Housing
Contracts, will be subject to any claims or defenses that the purchaser of the
related manufactured home may assert against the seller of the manufactured
home, subject to a maximum liability equal to the amounts paid by the obligor on
the Contract. If an obligor is successful in asserting any such claim or
defense, and if the Unaffiliated Seller had or should have had knowledge of such
claim or defense, the Master Servicer will have the right to require the
Unaffiliated Seller to repurchase the Contract because of a breach of its
Unaffiliated Seller's representation and warranty that no claims or defenses
exist which would affect the obligor's obligation to make the required payments
under the Contract. The Unaffiliated Seller would then have the right to require
the originating dealer to repurchase the Contract from it and might also have
the right to recover from the dealer for any losses suffered by the Unaffiliated
Seller with respect to which the dealer would have been primarily liable to the
obligor.
 
OTHER LIMITATIONS
 
     In addition to the laws limiting or prohibiting deficiency judgments,
numerous other statutory provisions, including Federal bankruptcy laws and
related state laws, may interfere with or affect the ability of a lender to
realize upon collateral and/or enforce a deficiency judgment. For example, in a
proceeding under the Federal bankruptcy law, a court may prevent a lender from
repossessing a home. In the case of an individual eligible for relief in a
proceeding under Chapter 11 of the Federal bankruptcy law, as part of the
rehabilitation plan under
 
                                       82
<PAGE>
Chapter 11, a court may reduce the amount of the secured indebtedness to the
market value of the home at the time of bankruptcy (as determined by the court),
leaving the party providing financing as a general unsecured creditor for the
remainder of the indebtedness. A bankruptcy court may also reduce the payments
due under a contract or change the rate of interest and time of repayment of the
indebtedness pursuant to a Chapter 11 plan of reorganization. Generally, any
plan filed in a proceeding under Chapter 13 of the Federal bankruptcy law must
provide for the full payment of the claim of the lender without changing the
terms of payment if the borrower elects to retain the property, the property is
the borrower's principal residence and the property is the lender's only
collateral.
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
     Unless the Prospectus Supplement indicates otherwise, all the related
Residential Loans, except for FHA Loans and VA Loans, contain due-on-sale
clauses. These clauses permit the lender to accelerate the maturity of the loan
if the borrower sells, transfers, or conveys the property without the prior
consent of the mortgagee. The enforceability of these clauses has been impaired
in various ways in certain states by statute or decisional law. The ability of
mortgage lenders and their assignees and transferees to enforce due-on-sale
clauses was addressed by the Garn-St. Germain Depository Institutions Act of
1982 (the "Garn-St. Germain Act") which was enacted on October 15, 1982. This
legislation, subject to certain exceptions, preempts state constitutional,
statutory and case law that prohibits the enforcement of due-on-sale clauses.
The Garn-St. Germain Act does "encourage" lenders to permit assumptions 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.
 
MORTGAGE LOANS
 
     Exempted from this preemption pursuant to the Garn-St. Germain Act are
mortgage loans (originated other than by federal savings and loan associations
and federal savings banks) that were made or assumed during the period beginning
on the date a state, by statute or final appellate court decision having
statewide effect, prohibited the exercise of due-on-sale clauses and ending on
October 15, 1982 ("Window Period Loans"). However, this exception applies only
to transfers of property underlying Window Period Loans occurring between
October 15, 1982 and October 15, 1985 and does not restrict enforcement of a
due-on-sale clause in connection with current transfers or property underlying
Window Period Loans unless the property underlying such Window Period Loan is
located in one of the three "window period states" identified below. Due-on-sale
clauses contained in Mortgage Loans originated by federal savings and loan
associations or federal savings banks are fully enforceable pursuant to
regulations of the Federal Home Loan Bank Board, predecessor to the Office of
Thrift Supervision, which preempt state law restrictions on the enforcement of
due-on-sale clauses. Mortgage Loans originated by such institutions are
therefore not deemed to be Window Period Loans.
 
     With the expiration of the exemption for Window Period Loans on October 15,
1985, 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", 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", three states (Michigan, 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. The Garn-St. Germain Act also sets forth nine
specific instances in which a mortgage lender covered by the Garn-St. Germain
Act (including federal savings and loan associations and federal savings banks)
may not exercise a due-on-sale clause, notwithstanding the fact that a transfer
of the property may have occurred. These include intra-family transfers, certain
transfers by operation of law, leases of fewer than three years, the creation of
a junior encumbrance and other instances where regulations promulgated by the
Director of the Office of Thrift Supervision (successor to the Federal Home Loan
Bank Board) prohibit such enforcement. To date no such regulations have been
issued. Regulations promulgated under the Garn-St. Germain Act prohibit the
imposition of a prepayment penalty upon the acceleration of a loan pursuant to a
due-on-sale clause.
 
     The inability to enforce a due-on-sale clause may result in a Mortgage Loan
bearing an interest rate below the current market rate being assumed by a new
home buyer rather than being paid off, which may have an impact upon the average
life of the Mortgage Loans related to a Series and the number of such Mortgage
Loans which may be outstanding until maturity.
 
                                       83
<PAGE>
TRANSFER OF MANUFACTURED HOMES
 
     Generally, manufactured housing contracts contain provisions prohibiting
the sale or transfer of the related manufactured homes without the consent of
the obligee on the contract and permitting the acceleration of the maturity of
such contracts by the obligee on the contract upon any such sale or transfer
that is not consented to. Unless otherwise provided in the related Prospectus
Supplement, 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 the related Contracts through enforcement of
"due-on-sale" clauses, subject to applicable state law. In certain cases, the
transfer may be made by a delinquent obligor in order to avoid a repossession
proceeding with respect to a Manufactured Home.
 
     In the case of a transfer of a Manufactured Home as to which the Master
Servicer desires to accelerate the maturity of the related Contract, the Master
Servicer's ability to do so will depend on the enforceability under state law of
the "due-on-sale" clause. The Garn-St. Germain Act preempts, subject to certain
exceptions and conditions, state laws prohibiting enforcement of "due-on-sale"
clauses applicable to the Manufactured Homes. Consequently, in some cases the
Master Servicer may be prohibited from enforcing a "due-on-sale" clause in
respect of certain Manufactured Homes.
 
PREPAYMENT CHARGES AND PREPAYMENTS
 
     Generally, conventional mortgage loans, Cooperative Loans, Home Improvement
and Manufactured Housing Contracts, residential owner occupied FHA loans and VA
loans may be prepaid in full or in part without penalty. Generally, multifamily
residential loans, including multifamily FHA Loans, may contain provisions
limiting prepayments on such loans, including prohibiting prepayment for a
specified period after origination, prohibiting partial prepayments entirely or
requiring the payment of a prepayment penalty upon prepayment in full or in
part.
 
     The laws of certain states may render prepayment fees unenforceable after a
Mortgage Loan has been outstanding for a certain number of years, or may limit
the amount of any prepayment fee to a specified percentage of the original
principal amount of the Mortgage Loan, to a specified percentage of the
outstanding principal balance of a Mortgage Loan, or to a fixed number of
months' interest on the prepaid amount. In certain states, prepayment fees
payable on default or other involuntary acceleration of a Residential Loan may
not be enforceable against the related mortgagor or obligor. Some state
statutory provisions may also treat certain prepayment fees as usurious if in
excess of statutory limits.
 
SUBORDINATE FINANCING
 
     When the mortgagor encumbers mortgaged property with one or more junior
liens, the senior lender is subjected to additional risk. First, the mortgagor
may have difficulty servicing and repaying multiple loans. In addition, if the
junior loan permits recourse to the mortgagor (as junior loans often do) and the
senior loan does not, a mortgagor may be more likely to repay sums due on the
junior loan than those on the senior loan. Second, acts of the senior lender
that prejudice the junior lender or impair the junior lender's security may
create a superior equity in favor of the junior lender. For example, if the
mortgagor and the senior lender agree to an increase in the principal amount of
or the interest rate payable on the senior loan, the senior lender may lose its
priority to the extent an existing junior lender is harmed or the mortgagor is
additionally burdened. Third, if the mortgagor defaults on the senior loan
and/or any junior loan or loans, the existence of junior loans and actions taken
by junior lenders can impair the security available to the senior lender and can
interfere with or delay the taking of action by the senior lender. Moreover, the
bankruptcy of a junior lender may operate to stay foreclosure or similar
proceedings by the senior lender.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V"), provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. A similar federal statute
was in effect with respect to mortgage loans made during the first three months
of 1980. The statute authorized any state to reimpose interest rate limits by
adopting, before April 1, 1983, a law or constitutional provision which
expressly rejects application of the federal law. In addition, even where Title
V is not so rejected, any state is authorized by
 
                                       84
<PAGE>
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 Depositor has been advised by counsel that a court interpreting Title V
would hold that mortgage loans related to a Series originated on or after
January 1, 1980 are subject to federal preemption. Therefore, in a state that
has not taken the requisite action to reject application of Title V or to adopt
a provision limiting discount points or other charges prior to origination of
such mortgage loans, any such limitation under such state's usury law would not
apply to such mortgage loans.
 
     In any state in which application of Title V has been expressly rejected or
a provision limiting discount points or other charges is adopted, no Mortgage
Loans originated after the date of such state action will be eligible for
inclusion in a Trust Fund if such Mortgage Loans bear interest or provide for
discount points or charges in excess of permitted levels. No Mortgage Loan
originated prior to January 1, 1980 will bear interest or provide for discount
points or charges in excess of permitted levels.
 
ALTERNATIVE MORTGAGE INSTRUMENTS
 
     ARM Loans originated by non-federally chartered lenders have historically
been subject to a variety of restrictions. Such restrictions differed from state
to state, resulting in difficulties in determining whether a particular
alternative mortgage instrument originated by a state-chartered lender complied
with applicable law. These difficulties were simplified substantially as a
result of the enactment of Title VIII of the Garn-St. Germain Act ("Title
VIII"). Title VIII provides that, notwithstanding any state law to the contrary,
(i) state-chartered banks may originate "alternative mortgage instruments"
(including ARM Loans) in accordance with regulations promulgated by the
Comptroller of the Currency with respect to origination of alternative mortgage
instruments by national banks, (ii) state-chartered credit unions may originate
alternative mortgage instruments in accordance with regulations promulgated by
the National Credit Union Administration with respect to origination of
alternative mortgage instruments by federal credit unions and (iii) all other
non-federally chartered housing creditors, including without limitation
state-chartered savings and loan associations, savings banks and mutual savings
banks and mortgage banking companies may originate alternative mortgage
instruments in accordance with the regulations promulgated by the Federal Home
Loan Bank Board, predecessor to the Office of Thrift Supervision, with respect
to origination of alternative mortgage instruments by federal savings and loan
associations. Title VIII further provides that any state may reject
applicability of the provisions of Title VIII by adopting, prior to October 15,
1985, a law or constitutional provision expressly rejecting the applicability of
such provisions. Certain states have taken such action.
 
ENVIRONMENTAL LEGISLATION
 
     Under the federal Comprehensive Environmental Response, Compensation and
Liability Act, as amended ("CERCLA"), and under state law in certain states, a
secured party which takes a deed-in-lieu of foreclosure, purchases a mortgaged
property at a foreclosure sale, or operates a mortgaged property may become
liable in certain circumstances for the costs of cleaning up hazardous
substances regardless of whether they have contaminated the property. CERCLA
imposes strict, as well as joint and several, liability on several classes of
potentially responsible parties, including current owners and operators of the
property who did not cause or contribute to the contamination. Furthermore,
liability under CERCLA is not limited to the original or unamortized principal
balance of a loan or to the value of the property securing a loan. Lenders may
be held liable under CERCLA as owners or operators unless they qualify for the
secured creditor exemption to CERCLA. This exemption exempts from the definition
of owners and operators those who, without participating in the management of a
facility, hold indicia of ownership primarily to protect a security interest in
the facility.
 
     The Asset Conservation, Lender Liability and Deposit Insurance Act of 1996
(the "Conservation Act") amended, among other things, the provisions of CERCLA
with respect to lender liability and the secured creditor exemption. The
Conservation Act offers protection to lenders by defining certain activities in
which a lender can engage and still have the benefit of the secured creditor
exemption. A lender will be deemed to have participated in the management of a
mortgaged property, and will lose the secured creditor exemption, if it actually
participates in the operational affairs of the property of the borrower. The
Conservation Act provides that "merely having the capacity to influence, or
unexercised right to control" operations does not constitute participation in
management. A lender will lose the protection of the secured creditor exemption
if it exercises
 
                                       85
<PAGE>
decision-making control over the borrower's environmental compliance and
hazardous substance handling and disposal practices, or assumes day-to-day
management of all operational functions of the mortgaged property. The
Conservation Act also provides that a lender may continue to have the benefit of
the secured creditor exemption even if it forecloses on a mortgaged property,
purchases it at a foreclosure sale or accepts a deed-in-lieu of foreclosure
provided that the lender seeks to sell the mortgaged property at the earliest
practicable commercially reasonable time on commercially reasonable terms.
 
     Other federal and state laws in certain circumstances may impose liability
on a secured party which takes a deed-in-lieu of foreclosure, purchases a
mortgaged property at a foreclosure sale, or operates a mortgaged property on
which contaminants other than CERCLA hazardous substances are present, including
petroleum, agricultural chemicals, hazardous wastes, asbestos, radon, and
lead-based paint. Such cleanup costs may be substantial. It is possible that
such cleanup costs could become a liability of a Trust Fund and reduce the
amounts otherwise distributable to the holders of the related Series of
Certificates. Moreover, certain federal statutes and certain states by statute
impose a lien for any cleanup costs incurred by such state on the property that
is the subject of such cleanup costs (an "Environmental Lien"). All subsequent
liens on such property generally are subordinated to such an Environmental Lien
and, in some states, even prior recorded liens are subordinated to Environmental
Liens. In the latter states, the security interest of the Trustee in a related
parcel of real property that is subject to such an Environmental Lien could be
adversely affected.
 
     Unless otherwise provided in the related Prospectus Supplement, the
Mortgage Loan Seller with respect to any Mortgage Loan included in a Trust Fund
for a particular Series of Securities will represent as to the material
compliance of the related Residential Property with applicable environmental
laws and regulations as of the date of transfer and assignment of such Mortgage
Loan to the Trustee. In addition, unless otherwise provided in the related
Prospectus Supplement, the related Agreement will provide that the Master
Servicer and any Special Servicer acting on behalf of the Trustee, may not
acquire title to a Residential Property or take over its operation unless the
Master Servicer (or Special Servicer) has previously determined, based on a
report prepared by a person who regularly conducts environmental audits, that
(a) there are no circumstances present at the Residential Property relating to
substances for which some action relating to their investigation or clean-up
could be required or that it would be in the best economic interest of the Trust
Fund to take such actions with respect to the affected Residential Property and
(b) that the Residential Property is in compliance with applicable environmental
laws or that it would be in the best economic interest of the Trust Fund to take
the actions necessary to comply with such laws. See "Description of the
Certificates--Realization Upon Defaulted Mortgage Loans."
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940
 
     Generally, under the terms of the Soldiers' and Sailors' Civil Relief Act
of 1940, as amended (the "Relief Act"), a mortgagor who enters military service
after the origination of such mortgagor's Mortgage Loan or Contract (including a
mortgagor who was in reserve status and is called to active duty after
origination of the Mortgage Loan), may not be charged interest (including fees
and charges) above an annual rate of 6% during the period of such mortgagor's
active duty status, unless a court orders otherwise upon application of the
lender. The Relief Act applies to mortgagors who are members of the Army, Navy,
Air Force, Marines, National Guard, Reserves, Coast Guard, and officers of the
U.S. Public Health Service assigned to duty with the military. Because the
Relief Act applies to mortgagors who enter military service (including
reservists who are called to active duty) after origination of the related
Mortgage Loan, no information can be provided as to the number of loans that may
be affected by the Relief Act. Application of the Relief Act would adversely
affect, for an indeterminate period of time, the ability of the Master Servicer
to collect full amounts of interest on certain of the Mortgage Loans. Any
shortfalls in interest collections resulting from the application of the Relief
Act would result in a reduction of the amounts distributable to the holders of
the related Series of Securities, and would not be covered by advances or,
unless otherwise specified in the related Prospectus Supplement, any form of
credit support provided in connection with such Securities. In addition, the
Relief Act imposes limitations that would impair the ability of the Master
Servicer to foreclose on an affected Mortgage Loan or enforce rights under a
Contract during the mortgagor's period of active duty status, and, under certain
circumstances, during an additional three month period thereafter. Thus, in the
event that such a Mortgage Loan or Contract goes into default, there may be
delays and losses occasioned thereby.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a general discussion of the anticipated material federal
income tax consequences of the purchase, ownership and disposition of the
Securities offered hereunder. This discussion is directed solely to
Securityholders that hold the Securities as capital assets within the meaning of
Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"), and
does not purport to discuss all federal income tax consequences that may be
applicable to particular categories of investors, some of which (such as banks,
insurance companies and foreign investors) may be subject to special rules.
Further, the authorities on which this discussion, and the opinion referred to
below, are based are subject to change or differing interpretations, which could
apply retroactively. In addition to the federal income tax consequences
described herein, potential investors should consider the state and local tax
consequences, if any, of the purchase, ownership and disposition of the
Securities. See "State and Other Tax Consequences." Securityholders are advised
to consult their own tax advisors concerning the federal, state, local or other
tax consequences to them of the purchase, ownership and disposition of the
Securities offered hereunder.
 
     The following discussion addresses securities of four general types: (i)
securities ("REMIC Securities") representing interests in a Trust Fund, or a
portion thereof, that the Trustee will elect to have treated as a real estate
mortgage investment conduit (the "REMIC") under Sections 860A through 860G (the
"REMIC Provisions") of the Code, (ii) securities ("Grantor Trust Securities")
representing interests in a Trust Fund ("Grantor Trust Fund") as to which no
such election will be made, (iii) securities ("Partnership Securities")
representing interests in a Trust Fund ("Partnership Trust Fund") which is
treated as a partnership or, if owned by a single beneficial owner, ignored for
federal income tax purposes, and (iv) securities ("Debt Securities")
representing indebtedness of a Partnership Trust Fund for federal income tax
purposes. The Prospectus Supplement for each Series of Securities will indicate
which of the foregoing treatments will apply to such Series and, if a REMIC
election (or elections) will be made for the related Trust Fund, will identify
all "regular interests" and "residual interests" in the REMIC. For purposes of
this tax discussion, (i) references to a "Securityholder" or a "holder" are to
the beneficial owner of a Security, (ii) references to "REMIC Pool" are to an
entity or portion thereof as to which a REMIC election will be made and (iii)
unless indicated otherwise in the applicable Prospectus Supplement, references
to "Mortgage Loans" include Agency Securities and Private Mortgage-Backed
Securities.
 
     The following discussion is based in part upon the rules governing original
issue discount that are set forth in Sections 1271-1273 and 1275 of the Code and
in the Treasury regulations issued thereunder (the "OID Regulations"), and in
part upon the REMIC Provisions and the Treasury regulations issued thereunder
(the "REMIC Regulations"). The OID Regulations do not adequately address certain
issues relevant to, and in some instances provide that they are not applicable
to, securities such as the Securities.
 
REMICS
 
CLASSIFICATION OF REMICS
 
     Upon the issuance of each Series of REMIC Securities, Cadwalader,
Wickersham & Taft, special counsel to the Depositor, will deliver its opinion
generally to the effect that, assuming compliance with all provisions of the
related Pooling and Servicing Agreement, the related Trust Fund (or each
applicable portion thereof) will qualify as a REMIC and the REMIC Securities
offered with respect thereto will be considered to evidence ownership of
"regular interests" ("Regular Securities") or "residual interests" ("Residual
Securities") in that REMIC within the meaning of the REMIC Provisions.
 
     In order for the REMIC Pool to qualify as a REMIC, there must be ongoing
compliance on the part of the REMIC Pool with the requirements set forth in the
Code. The REMIC Pool must fulfill an asset test, which requires that no more
than a de minimis portion of the assets of the REMIC Pool, as of the close of
the third calendar month beginning after the "Startup Day" (which for purposes
of this discussion is the date of issuance of the REMIC Securities) and at all
times thereafter, may consist of assets other than "qualified mortgages" and
"permitted investments." The REMIC Regulations provide a safe harbor pursuant to
which the de minimis requirement will be met if at all times the aggregate
adjusted basis of the nonqualified assets is less than 1% of
 
                                       87
<PAGE>
the aggregate adjusted basis of all the REMIC Pool's assets. An entity that
fails to meet the safe harbor may nevertheless demonstrate that it holds no more
than a de minimis amount of nonqualified assets. A REMIC Pool also must provide
"reasonable arrangements" to prevent its residual interests from being held by
"disqualified organizations" or agents thereof and must furnish applicable tax
information to transferors or agents that violate this requirement. The Pooling
and Servicing Agreement with respect to each Series of REMIC Securities will
contain provisions meeting these requirements. See "Taxation of Owners of
Residual Securities--Tax-Related Restrictions on Transfer of Residual
Securities--Disqualified Organizations."
 
     A qualified mortgage is any obligation that is principally secured by an
interest in real property and that is either transferred to the REMIC Pool on
the Startup Day or is purchased by the REMIC Pool within a three-month period
thereafter pursuant to a fixed price contact in effect on the Startup Day.
Qualified mortgages include whole mortgage loans, such as the Mortgage Loans,
and, generally, certificates of beneficial interest in a grantor trust that
holds mortgage loans and regular interests in another REMIC, such as lower-tier
regular interests in a tiered REMIC. The REMIC Regulations specify that loans
secured by timeshare interests and shares held by a tenant stockholder in a
cooperative housing corporation can be qualified mortgages. A qualified mortgage
includes a qualified replacement mortgage, which is any property that would have
been treated as a qualified mortgage if it were transferred to the REMIC Pool on
the Startup Day and that is received either (i) in exchange for any qualified
mortgage within a three-month period thereafter or (ii) in exchange for a
"defective obligation" within a two-year period thereafter. A "defective
obligation" includes (i) a mortgage in default or as to which default is
reasonably foreseeable, (ii) a mortgage as to which a customary representation
or warranty made at the time of transfer to the REMIC Pool has been breached,
(iii) a mortgage that was fraudulently procured by the mortgagor, and (iv) a
mortgage that was not in fact principally secured by real property (but only if
such mortgage is disposed of within 90 days of discovery). A Mortgage Loan that
is "defective" as described in clause (iv) that is not sold or, if within two
years of the Startup Day, exchanged, within 90 days of discovery, ceases to be a
qualified mortgage after such 90-day period.
 
     Permitted investments include cash flow investments, qualified reserve
assets, and foreclosure property. A cash flow investment is an investment,
earning a return in the nature of interest, of amounts received on or with
respect to qualified mortgages for a temporary period, not exceeding 13 months,
until the next scheduled distribution to holders of interests in the REMIC Pool.
A qualified reserve asset is any intangible property held for investment that is
part of any reasonably required reserve maintained by the REMIC Pool to provide
for payments of expenses of the REMIC Pool or amounts due on the regular or
residual interests in the event of defaults (including delinquencies) on the
qualified mortgages, lower than expected reinvestment returns, prepayment
interest shortfalls and certain other contingencies. The reserve fund will be
disqualified if more than 30% of the gross income from the assets in such fund
for the year is derived from the sale or other disposition of property held for
less than three months, unless required to prevent a default on the regular
interests caused by a default on one or more qualified mortgages. A reserve fund
must be reduced "promptly and appropriately" as payments on the Mortgage Loans
are received. Foreclosure property is real property acquired by the REMIC Pool
in connection with the default or imminent default of a qualified mortgage and
generally not held beyond the close of the third calendar year following the
year of acquisition, with one extension available from the Internal Revenue
Service.
 
     In addition to the foregoing requirements, the various interests in a REMIC
Pool also must meet certain requirements. All of the interests in a REMIC Pool
must be either of the following: (i) one or more classes of regular interests or
(ii) a single class of residual interests on which distributions, if any, are
made pro rata. A regular interest is an interest in a REMIC Pool that is issued
on the Startup Day with fixed terms, is designated as a regular interest, and
unconditionally entitles the holder to receive a specified principal amount (or
other similar amount), and provides that interest payments (or other similar
amounts), if any, at or before maturity either are payable based on a fixed rate
or a qualified variable rate, or consist of a specified, nonvarying portion of
the interest payments on qualified mortgages. Such a specified portion may
consist of a fixed number of basis points, a fixed percentage of the total
interest, or a qualified variable rate, inverse variable rate or difference
between two fixed or qualified variable rates on some or all of the qualified
mortgages. The specified principal amount of a regular interest that provides
for interest payments consisting of a specified, nonvarying portion of interest
payments on qualified mortgages may be zero. A residual interest is an interest
in a REMIC Pool other than a regular interest that is issued on the Startup Day
and that is designated as a residual interest. An interest in a REMIC Pool may
be treated as a regular interest even if payments of principal with respect to
such interest are
 
                                       88
<PAGE>
subordinated to payments on other regular interests or the residual interest in
the REMIC Pool, and are dependent on the absence of defaults or delinquencies on
qualified mortgages or permitted investments, lower than reasonably expected
returns on permitted investments, unanticipated expenses incurred by the REMIC
Pool or prepayment interest shortfalls. Accordingly, the Regular Securities of a
Series will constitute one or more classes of regular interests, and the
Residual Securities with respect to that Series will constitute a single class
of residual interests with respect to each REMIC Pool.
 
     If an entity electing to be treated as a REMIC fails to comply with one or
more of the ongoing requirements of the Code for such status during any taxable
year, the Code provides that the entity will not be treated as a REMIC for such
year and thereafter. In that event, such entity may be taxable as a corporation
under Treasury regulations, and the related REMIC Securities may not be accorded
the status or given the tax treatment described below. Although the Code
authorizes the Treasury Department to issue regulations providing relief in the
event of an inadvertent termination of REMIC status, no such regulations have
been issued. Any such relief, moreover, may be accompanied by sanctions, such as
the imposition of a corporate tax on all or a portion of the Trust Fund's income
for the period in which the requirements for such status are not satisfied. The
Pooling and Servicing Agreement with respect to each REMIC Pool will include
provisions designed to maintain the Trust Fund's status as a REMIC under the
REMIC Provisions. It is not anticipated that the status of any Trust Fund as a
REMIC will be terminated.
 
CHARACTERIZATION OF INVESTMENTS IN REMIC SECURITIES
 
     In general, the REMIC Securities will be treated as "real estate assets"
within the meaning of Section 856(c)(4)(A) of the Code and assets described in
Section 7701(a)(19)(C) of the Code in the same proportion that the assets of the
REMIC Pool underlying such Securities would be so treated. Moreover, if 95% or
more of the assets of the REMIC Pool qualify for either of the foregoing
treatments at all times during a calendar year, the REMIC Securities will
qualify for the corresponding status in their entirety for that calendar year.
If the assets of the REMIC Pool include Buydown Loans, it is possible that the
percentage of such assets constituting "loans . . . secured by an interest in
real property which is . . . residential real property" for purposes of Code
Section 7701(a)(19)(C)(v) may be required to be reduced by the amount of the
related funds paid thereon (the "Buydown Funds"). Interest (including original
issue discount) on the Regular Securities and income allocated to the class of
Residual Securities will be interest described in Section 856(c)(3)(B) of the
Code to the extent that such Securities are treated as "real estate assets"
within the meaning of Section 856(c)(4)(A) of the Code. In addition, the Regular
Securities will be "qualified mortgages" within the meaning of Section
860G(a)(3) of the Code if transferred to another REMIC on its Startup Day in
exchange for regular or residual interests therein, and will be "permitted
assets" within the meaning of Section 860L(c) for a financial asset
securitization investment trust. The determination as to the percentage of the
REMIC Pool's assets that constitute assets described in the foregoing sections
of the Code will be made with respect to each calendar quarter based on the
average adjusted basis of each category of the assets held by the REMIC Pool
during such calendar quarter. The REMIC will report those determinations to
Securityholders in the manner and at the times required by applicable Treasury
regulations. The Small Business Job Protection Act of 1996 (the "SBJPA of 1996")
repealed the reserve method of bad debts of domestic building and loan
associations and mutual savings banks, and thus has eliminated the asset
category of "qualifying real property loans" in former Code Section 593(d) for
taxable years beginning after December 31, 1995. The requirements in the SBJPA
of 1996 that such institutions must "recapture" a portion of their existing bad
debt reserves is suspended if a certain portion of their assets are maintained
in "residential loans" under Code Section 7701(a)(19)(C)(v), but only if such
loans were made to acquire, construct or improve the related real property and
not for the purpose of refinancing. However, no effort will be made to identify
the portion of the Mortgage Loans of any Series meeting this requirement, and no
representation is made in this regard.
 
     The assets of the REMIC Pool will include, in addition to Mortgage Loans,
payments on Mortgage Loans held pending distribution on the REMIC Securities and
property acquired by foreclosure held pending sale, and may include amounts in
reserve accounts. It is unclear whether property acquired by foreclosure held
pending sale and amounts in reserve accounts would be considered to be part of
the Mortgage Loans, or whether such assets (to the extent not invested in assets
described in the foregoing sections) otherwise would receive the same treatment
as the Mortgage Loans for purposes of all of the foregoing sections. The REMIC
Regulations do provide, however, that payments on Mortgage Loans held pending
distribution are considered part of the
 
                                       89
<PAGE>
Mortgage Loans for purposes of Section 856(c)(4)(A) of the Code. Furthermore,
foreclosure property will qualify as "real estate assets" under
Section 856(c)(4)(A) of the Code.
 
TIERED REMIC STRUCTURES
 
     For certain Series of REMIC Securities, two or more separate elections may
be made to treat designated portions of the related Trust Fund as REMICs
("Tiered REMICs") for federal income tax purposes. Upon the issuance of any such
Series of REMIC Securities, Cadwalader, Wickersham & Taft will deliver its
opinion generally to the effect that, assuming compliance with all provisions of
the related Pooling and Servicing Agreement, the Tiered REMICs will each qualify
as a REMIC and the REMIC Securities issued by the Tiered REMICs, respectively,
will be considered to evidence ownership of Regular Securities or Residual
Securities in the related REMIC within the meaning of the REMIC Provisions.
 
     Solely for purposes of determining whether the REMIC Securities will be
"real estate assets" within the meaning of Section 856(c)(4)(A) of the Code and
"loans secured by an interest in real property" under
Section 7701(a)(19)(C) of the Code, and whether the income on such Securities is
interest described in Section 856(c)(3)(B) of the Code, the Tiered REMICs will
be treated as one REMIC.
 
TAXATION OF OWNERS OF REGULAR SECURITIES
 
GENERAL
 
     In general, interest, original issue discount, and market discount on a
Regular Security will be treated as ordinary income to a holder of the Regular
Security (the "Regular Securityholder"), and principal payments on a Regular
Security will be treated as a return of capital to the extent of the Regular
Securityholder's basis in the Regular Security allocable thereto. Regular
Securityholders must use the accrual method of accounting with regard to Regular
Securities, regardless of the method of accounting otherwise used by such
Regular Securityholder.
 
ORIGINAL ISSUE DISCOUNT
 
     Regular Securities may be issued with "original issue discount" within the
meaning of Code Section 1273(a). Holders of any Class or Subclass of Regular
Securities having original issue discount generally must include original issue
discount in ordinary income for federal income tax purpose as it accrues, in
accordance with a constant yield method that takes into account the compounding
of interest, in advance of the receipt of the cash attributable to such income.
The following discussion is based in part on temporary and final Treasury
regulations issued on February 2, 1994, as amended on June 14, 1996, (the "OID
Regulations") under Code Section 1271 through 1273 and 1275 and in part on the
provisions of the 1986 Act. Regular Securityholders should be aware, however,
that the OID Regulations do not adequately address certain issues relevant to
prepayable securities, such as the Regular Securities. To the extent such issues
are not addressed in such regulations, it is anticipated that the Trustee will
apply the methodology described in the Conference Committee Report to the 1986
Act. No assurance can be provided that the Internal Revenue Service will not
take a different position as to those matters not currently addressed by the OID
Regulations. Moreover, the OID Regulations include an anti-abuse rule allowing
the Internal Revenue Service to apply or depart from the OID Regulations where
necessary or appropriate to ensure a reasonable tax result in light of the
applicable statutory provisions. A tax result will not be considered
unreasonable under the anti-abuse rule in the absence of a substantial effect on
the present value of a taxpayer's tax liability. Investors are advised to
consult their own tax advisors as to the discussion therein and the appropriate
method for reporting interest and original issue discount with respect to the
Regular Securities.
 
     Each Regular Security (except to the extent described below with respect to
a Regular Security on which principal is distributed in a single installment or
by lots of specified principal amounts upon the request of a Securityholder or
by random lot (a "Non-Pro Rata Security")) will be treated as a single
installment obligation for purposes of determining the original issue discount
includible in a Regular Securityholder's income. The total amount of original
issue discount on a Regular Security is the excess of the "stated redemption
price at maturity" of the Regular Security over its "issue price." The issue
price of a Class of Regular Securities offered pursuant to this Prospectus
generally is the first price at which a substantial amount of such Class is sold
to the
 
                                       90
<PAGE>
public (excluding bond houses, brokers and underwriters). Although unclear under
the OID Regulations, it is anticipated that the Trustee will treat the issue
price of a Class as to which there is no substantial sale as of the issue date
or that is retained by the Depositor as the fair market value of the Class as of
the issue date. The issue price of a Regular Security also includes any amount
paid by an initial Regular Securityholder for accrued interest that relates to a
period prior to the issue date of the Regular Security, unless the Regular
Securityholder elects on its federal income tax return to exclude such amount
from the issue price and to recover it on the first Distribution Date. The
stated redemption price at maturity of a Regular Security always includes the
original principal amount of the Regular Security, but generally will not
include distributions of interest if such distributions constitute "qualified
stated interest." Under the OID Regulations, qualified stated interest generally
means interest payable at a single fixed rate or a 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 Regular
Security. Because there is no penalty or default remedy in the case of
nonpayment of interest with respect to a Regular Security, it is possible that
no interest on any Class of Regular Securities will be treated as qualified
stated interest. However, except as provided in the following three sentences or
in the applicable Prospectus Supplement, because the underlying Mortgage Loans
provide for remedies in the event of default, it is anticipated that the Trustee
will treat interest with respect to the Regular Securities as qualified stated
interest. Distributions of interest on Regular Securities with respect to which
deferred interest will accrue, will not constitute qualified stated interest, in
which case the stated redemption price at maturity of such Regular Securities
includes all distributions of interest as well as principal thereon. Likewise,
it is anticipated that the Trustee will treat an interest-only Class or a Class
on which interest is substantially disproportionate to its principal amount (a
so-called "super-premium" Class) as having no qualified stated interest. Where
the interval between the issue date and the first Distribution Date on a Regular
Security is shorter than the interval between subsequent Distribution Dates, the
interest attributable to the additional days will be included in the stated
redemption price at maturity.
 
     Under a de minimis rule, original issue discount on a Regular Security will
be considered to be zero if such original issue discount is less than 0.25% of
the stated redemption price at maturity of the Regular Security multiplied by
the weighted average maturity of the Regular Security. For this purpose, the
weighted average maturity of the Regular 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 Regular Security and the denominator of
which is the stated redemption price at maturity of the Regular Security. The
Conference Committee Report to the 1986 Act provides that the schedule of such
distributions should be determined in accordance with the assumed rate of
prepayment of the Mortgage Loans (the "Prepayment Assumption") and the
anticipated reinvestment rate, if any, relating to the Regular Securities. The
Prepayment Assumption with respect to a Series of Regular Securities will be set
forth in the applicable Prospectus Supplement. Holders generally must report de
minimis original issue discount pro rata as principal payments are received, and
such income will be capital gain if the Regular Security is held as a capital
asset. Under the OID Regulations, however, Regular Securityholders may elect to
accrue all de minimis original issue discount as well as market discount and
market premium, under the constant yield method. See "Election to Treat All
Interest Under the Constant Yield Method."
 
     A Regular Securityholder generally must include in gross income for any
taxable year the sum of the "daily portions", as defined below, of the original
issue discount on the Regular Security accrued during an accrual period for each
day on which it holds the Regular Security, including the date of purchase but
excluding the date of disposition. The Trustee will treat the monthly period
ending on the day before each Distribution Date as the accrual period. With
respect to each Regular Security, a calculation will be made of the original
issue discount that accrues during each successive full accrual period (or
shorter period from the date of original issue) that ends on the day before the
related Distribution Date on the Regular Security. The Conference Committee
Report to the 1986 Act states that the rate of accrual of original issue
discount is intended to be based on the Prepayment Assumption. The original
issue discount accruing in a full accrual period would be the excess, if any, of
(i) the sum of (a) the present value of all of the remaining distributions to be
made on the Regular Security as of the end of that accrual period, and (b) the
distributions made on the Regular Security during the accrual period that are
included in the Regular Security's stated redemption price at maturity, over
(ii) the adjusted issue price of the Regular Security at the beginning of the
accrual period. The present value of the remaining distributions referred to in
the preceding sentence is calculated based on (i) the yield to maturity of the
Regular Security at the issue
 
                                       91
<PAGE>
date, (ii) events (including actual prepayments) that have occurred prior to the
end of the accrual period, and (iii) the Prepayment Assumption. For these
purposes, the adjusted issue price of a Regular Security at the beginning of any
accrual period equals the issue price of the Regular Security, increased by the
aggregate amount of original issue discount with respect to the Regular Security
that accrued in all prior accrual periods and reduced by the amount of
distributions included in the Regular Security's stated redemption price at
maturity that were made on the Regular Security in such prior periods. The
original issue discount accruing during any accrual period (as determined in
this paragraph) will then be divided by the number of days in the period to
determine the daily portion of original issue discount for each day in the
period. With respect to an initial accrual period shorter than a full accrual
period, the daily portions of original issue discount must be determined
according to an appropriate allocation under any reasonable method.
 
     Under the method described above, the daily portions of original issue
discount required to be included in income by a Regular Securityholder generally
will increase to take into account prepayments on the Regular Securities as a
result of prepayments on the Mortgage Loans that exceed the Prepayment
Assumption, and generally will decrease (but not below zero for any period) if
the prepayments are slower than the Prepayment Assumption. As increase in
prepayments on the Mortgage Loans with respect to a Series of Regular Securities
can result in both a change in the priority of principal payments with respect
to certain Classes of Regular Securities and either an increase or decrease in
the daily portions of original issue discount with respect to such Regular
Securities.
 
     In the case of a Non-Pro Rata Security, it is anticipated that the Trustee
will determine the yield to maturity of such Security based upon the anticipated
payment characteristics of the Class as a whole under the Prepayment Assumption.
In general, the original issue discount accruing on each Non-Pro Rata Security
in a full accrual period would be its allocable share of the original issue
discount with respect to the entire Class, as determined in accordance with the
preceding paragraph. However, in the case of a distribution in retirement of the
entire unpaid principal balance of any Non-Pro Rata Security (or portion of such
unpaid principal balance), (a) the remaining unaccrued original issue discount
allocable to such Security (or to such portion) will accrue at the time of such
distribution, and (b) the accrual of original issue discount allocable to each
remaining Security of such Class (or the received) will be adjusted by reducing
the present value of the remaining payments on such Class and the adjusted issue
price of such Class to the extent attributable to the portion of the unpaid
principal balance thereof that was distributed. The Depositor believes that the
foregoing treatment is consistent with the "pro rata prepayment" rules of the
OID Regulations, but with the rate of accrual of original issue discount
determined based on the Prepayment Assumption for the Class as a whole.
Investors are advised to consult their tax advisors as to this treatment.
 
ACQUISITION PREMIUM
 
     A purchaser of a Regular Security at a price greater than its adjusted
issue price but less than its stated redemption price at maturity will be
required to include in gross income the daily portions of the original issue
discount on the Regular Security reduced pro rata by a fraction, the numerator
of which is the excess of its purchase price over such adjusted issue price and
the denominator of which is the excess of the remaining stated redemption price
at maturity over the adjusted issue price. Alternatively, such a subsequent
purchaser may elect to treat all such acquisition premium under the constant
yield method, as described below under the heading "Election to Treat All
Interest Under the Constant Yield Method."
 
VARIABLE RATE REGULAR SECURITIES
 
     Regular Securities may provide for interest based on a variable rate. Under
the OID Regulations, interest is treated as payable at a variable rate if,
generally, (i) the issue price does not exceed the original principal balance by
more than a specified amount and (ii) the interest compounds or is payable at
least annually at current values of (a) one or more "qualified floating rates",
(b) a single fixed rate and one or more qualified floating rates, (c) a single
"objective rate", or (d) a single fixed rate and a single objective rate that is
a "qualified inverse floating rate." A floating rate is a qualified floating
rate if variations can reasonably be expected to measure contemporaneous
variations in the cost of newly borrowed funds, where such rate is subject to a
fixed multiple that is greater that 0.65 but not more than 1.35. Such rate may
also be increased or decreased by a fixed spread or subject to a fixed cap or
floor, or a cap or floor that is not reasonably expected as of the issue date to
affect the
 
                                       92
<PAGE>
yield of the instrument significantly. An objective rate is any rate (other than
a qualified floating rate) that is determined using a single fixed formula and
that is based on objective financial or economic information, provided that such
information is not (i) within the control of the issuer or a related party or
(ii) unique to the circumstances of the issuer or a related party. A qualified
inverse floating rate is a rate equal to a fixed rate minus a qualified floating
rate that inversely reflects contemporaneous variations in the cost of newly
borrowed funds; an inverse floating rate that is not a qualified inverse
floating rate may nevertheless be an objective rate. A Class of Regular
Securities may be issued under this Prospectus that does not have a variable
rate under the foregoing rules, for example, a Class that bears different rates
at different times during the period it is outstanding such that it is
considered significantly "front-loaded" or "back-loaded" within the meaning of
the OID Regulations. It is possible that such a Class may be considered to bear
"contingent interest" within the meaning of the OID Regulations. The OID
Regulations, as they relate to the treatment of contingent interest, are by
their terms not applicable to Regular Securities. However, if final regulations
dealing with contingent interest with respect to Regular Securities apply the
same principles as the OID Regulations, such regulations may lead to different
timing of income inclusion that would be the case under the OID Regulations.
Furthermore, application of such principles could lead to the characterization
of gain on the sale of contingent interest Regular Securities as ordinary
income. Investors should consult their tax advisors regarding the appropriate
treatment of any Regular Security that does not pay interest at a fixed rate or
variable rate as described in this paragraph.
 
     Under the REMIC Regulations, a Regular Security (i) bearing a rate that
qualifies as a variable rate under the OID Regulations that is tied to current
values of a variable rate (or the highest, lowest or average of two or more
variable rates, including a rate based on the average cost of funds of one or
more financial institutions), or a positive or negative multiple of such a rate
(plus or minus a specified number of basis points), or that represents a
weighted average of rates on some or all of the Mortgage Loans, including such a
rate that is subject to one or more caps or floors, or (ii) bearing one or more
such variable rates for one or more periods, or one or more fixed rates for one
or more periods, and a different variable rate or fixed rate for other periods,
qualifies as a regular interest in a REMIC. Accordingly, unless otherwise
indicated in the applicable Prospectus Supplement, it is anticipated that the
Trustee will treat Regular Securities that qualify as regular interests under
this rule in the same manner as obligations bearing a variable rate for original
issue discount reporting purposes.
 
     The amount of original issue discount with respect to a Regular Security
bearing a variable rate of interest will accrue in the manner described above
under "Original Issue Discount", with the yield to maturity and future payments
on such Regular Security generally to be determined by assuming that interest
will be payable for the life of the Regular Security based on the initial rate
(or, if different, the value of the applicable variable rate as of the pricing
date) for the relevant Class. Unless required otherwise by applicable final
regulations, it is anticipated that the Trustee will treat such variable
interest as qualified stated interest, other than variable interest on an
interest-only or super-premium Class, which will be treated as non-qualified
stated interest includible in the stated redemption price at maturity. Ordinary
income reportable for any period will be adjusted based on subsequent changes in
the applicable interest rate index.
 
     Although unclear under the OID Regulations, unless required otherwise by
applicable final regulations, it is anticipated that the Trustee will treat
Regular Securities bearing an interest rate that is a weighted average of the
net interest rates on Mortgage Loans as having qualified stated interest, except
to the extent that initial "teaser" rates cause sufficiently "back-loaded"
interest to create more than de minimis original issue discount. The yield on
such Regular Securities for purposes of accruing original issue discount will be
a hypothetical fixed rate based on the fixed rates, in the case of fixed rate
Mortgage Loans, and initial "teaser rates" followed by fully indexed rates, in
the case of adjustable rate Mortgage Loans. In the case of adjustable rate
Mortgage Loans, the applicable index used to compute interest on the Mortgage
Loans in effect on the pricing date (or possibly the issue date) will be deemed
to be in effect beginning with the period in which the first weighted average
adjustment date occurring after the issue date occurs. Adjustments will be made
in each accrual period either increasing or decreasing the amount of ordinary
income reportable to reflect the actual Pass-Through Rate on the Regular
Securities.

<PAGE>
MARKET DISCOUNT
 
     A purchaser of a Regular Security also may be subject to the market
discount rules of Code Sections 1276 through 1278. Under these sections and the
principles applied by the OID Regulations in the context of original issue
discount, "market discount" is the amount by which the purchaser's original
basis in the Regular Security (i) is exceeded by the then-current principal
amount of the Regular Security, or (ii) in the case of a Regular Security having
original issue discount, is exceeded by the adjusted issue price of such Regular
Security at the time of purchase. Such purchaser generally will be required to
recognize ordinary income to the extent of accrued market discount on such
Regular Security as distributions includible in the stated redemption price at
maturity thereof are received, in an amount not exceeding any such distribution.
Such market discount would accrue in a manner to be provided in Treasury
regulations and should take into account the Prepayment Assumption. The
Conference Committee Report to the 1986 Act provides that until such regulations
are issued, such market discount would accrue either (i) on the basis of a
constant interest rate, or (ii) in the ratio of stated interest allocable to the
relevant period to the sum of the interest for such period plus the remaining
interest as of the end of such period, or in the case of a Regular Security
issued with original issue discount, in the ratio of original issue discount
accrued for the relevant period to the sum of the original issue discount
accrued for such period plus the remaining original issue as of the end of such
period. Such purchaser also generally will be required to treat a portion of any
gain on a sale or exchange of the Regular Security as ordinary income to the
extent of the market discount accrued to the date of disposition under one of
the foregoing methods, less any accrued market discount previously reported as
ordinary income as partial distributions in reduction of the stated redemption
price at maturity were received. Such purchaser will be required to defer
deduction of a portion of the excess of the interest paid or accrued on
indebtedness incurred to purchase or carry a Regular Security over the interest
distributable thereon. The deferred portion of such interest expense in any
taxable year generally will not exceed the accrued market discount on the
Regular Security for such year. Any such deferred interest expense is, in
general, allowed as a deduction not later than the year in which the related
market discount income is recognized or the Regular Security is disposed of. As
an alternative to the inclusion of market discount in income on the foregoing
basis, the Regular Securityholder may elect to include market discount in income
currently as it accrues on all market discount instruments acquired by such
Regular Securityholder in that taxable year or thereafter, in which case the
interest deferral rule will not apply. See "Election to Treat All Interest Under
the Constant Yield Method" below regarding an alternative manner in which such
election may be deemed to be made.
 
     By analogy to the OID Regulations, market discount with respect to a
Regular Security will be considered to be zero if such market discount is less
than 0.25% of the remaining stated redemption price at maturity of such Regular
Security multiplied by the weighted average maturity of the Regular Security
(determined as described above in the third paragraph under "Original Issue
Discount") remaining after the date of purchase. It appears that de minimis
market discount would be reported in a manner similar to de minimis original
issue discount. See "Original Issue Discount" above. Treasury regulations
implementing the market discount rules have not yet been issued, and therefore
investors should consult their own tax advisors regarding the application of
these rules. Investors should also consult Revenue Procedure 92-67 concerning
the elections to include market discount in income currently and to accrue
market discount on the basis of the constant yield method.
 
PREMIUM
 
     A Regular Security purchased at a cost greater than its remaining stated
redemption price at maturity generally is considered to be purchased at a
premium. If the Regular Securityholder holds such Regular Security as a "capital
asset" within the meaning of Code Section 1221, the Regular Securityholder may
elect under Code Section 171 to amortize such premium under the constant yield
method. Such election will apply to all debt obligations acquired by the Regular
Securityholder at a premium held in that taxable year or thereafter, unless
revoked with the permission of the Internal Revenue Service. Final Treasury
regulations with respect to amortization of bond premiums do not by their terms
apply to obligations, such as the Regular Securities, which are prepayable as
described in Code Secion 1272(a)(6). However, the Conference Committee Report to
the 1986 Act indicates a Congressional intent that the same rules that apply to
the accrual of market discount on installment obligations will also apply to
amortizing bond premium under Code Section 171 on installment obligations such
as the Regular Securities, although it is unclear whether the alternatives to
the constant interest method described above under "Market Discount" are
available. Amortizable bond premium will be treated as
 
                                       94
<PAGE>
an offset to interest income on a Regular Security, rather than as a separate
deductible item. See "Election to Treat All Interest Under the Constant Yield
Method" below regarding an alternative manner in which the Code Section 171
election may be deemed to be made.
 
ELECTION TO TREAT ALL INTEREST UNDER THE CONSTANT YIELD METHOD
 
     A holder of a debt instrument such as a Regular Security may elect to treat
all interest that accrues on the instrument using the constant yield method,
with none of the interest being treated as qualified stated interest. For
purposes of applying the constant yield method to a debt instrument subject to
such an election, (i) "interest" includes stated interest, original issue
discount, de minimis original issue discount, market discount and de minimis
market discount, as adjusted by any amortizable bond premium or acquisition
premium and (ii) the debt instrument is treated as if the instrument were issued
on the holder's acquisition date in the amount of the holder's adjusted basis
immediately after acquisition. It is unclear whether, for this purpose, the
initial Prepayment Assumption would continue to apply or if a new prepayment
assumption as of the date of the holder's acquisition would apply. A holder
generally may make such an election on an instrument by instrument basis or for
a class or group of debt instruments. However, if the holder makes such an
election with respect to a debt instrument with amortizable bond premium or with
market discount, the holder is deemed to have made elections to amortize bond
premium or to report market discount income currently as it accrues under the
constant yield method, respectively, for all premium bonds held or market
discount bonds acquired by the holder in the same taxable year or thereafter.
The election is made on the holder's federal income tax return for the year in
which the debt instrument is acquired and is irrevocable except with the
approval of the Internal Revenue Service. Investors should consult their own tax
advisors regarding the advisability of making such an election.
 
TREATMENT OF LOSSES
 
     Regular Securityholders will be required to report income with respect to
Regular Securities on the accrual method of accounting, without giving effect to
delays or reductions in distributions attributable to defaults or delinquencies
on the Mortgage Loans, except to the extent it can be established that such
losses are uncollectible. Accordingly, the holder of a Regular Security,
particularly a Subordinate Security, may have income, or may incur a diminution
in cash flow as a result of a default or delinquency, but may not be able to
take a deduction (subject to the discussion below) for the corresponding loss
until a subsequent taxable year. In this regard, investors are cautioned that
while they may generally cease to accrue interest income if it reasonably
appears that the interest will be uncollectible, the Internal Revenue Service
may take the position that original issue discount must continue to be accrued
in spite of its uncollectibility until the debt instrument is disposed of in a
taxable transaction or becomes worthless in accordance with the rules of Code
Section 166. To the extent the rules of Code Section 166 regarding bad debts are
applicable, it appears that Regular Securityholders that are corporations or
that otherwise hold the Regular Securities in connection with a trade or
business should in general be allowed to deduct as an ordinary loss such loss
with respect to principal sustained during the taxable year on account of any
such Regular Securities becoming wholly or partially worthless, and that, in
general, Regular Securityholders that are not corporations and do not hold the
Regular Securities in connection with a trade or business should be allowed to
deduct as a short-term capital loss any loss sustained during the taxable year
on account of a portion of any such Regular Securities becoming wholly
worthless. Although the matter is not free from doubt, such non-corporate
Regular Securityholders should be allowed a bad debt deduction at such time as
the principal balance of such Regular Securities is reduced to reflect losses
resulting from any liquidated Mortgage Loans. The Internal Revenue Service,
however, could take the position that non-corporate holders will be allowed a
bad debt deduction to reflect such losses only after all the Mortgage Loans
remaining in the Trust Estate have been liquidated or the applicable Class of
Regular Securities has been otherwise retired. The Internal Revenue Service
could also assert that losses on the Regular Securities are deductible based on
some other method that may defer such deductions for all holders, such as
reducing future cashflow for purposes of computing original issue discount. This
may have the effect of creating "negative" original issue discount which would
be deductible only against future positive original issue discount or otherwise
upon termination of the Class. Regular Securityholders are urged to consult
their own tax advisors regarding the appropriate timing, amount and character of
any loss sustained with respect to such Regular Securities. While losses
attributable to interest previously reported as income should be deductible as
ordinary losses by both corporate and non-corporate holders, the Internal
Revenue Service may take the position that losses attributable to accrued
original
 
                                       95
<PAGE>
issue discount may only be deducted as capital losses in the case of
non-corporate holders who do not hold the Regular Securities in connection with
a trade or business. Special loss rules are applicable to banks and thrift
institutions, including rules regarding reserves for bad debts. Such taxpayers
are advised to consult their tax advisors regarding the treatment of losses on
Regular Securities.
 
SALE OR EXCHANGE OF REGULAR SECURITIES
 
     If a Regular Securityholder sells or exchanges a Regular Security, the
Regular Securityholder will recognize gain or loss equal to the difference, if
any, between the amount received and its adjusted basis in the Regular Security.
The adjusted basis of a Regular Security generally will equal the cost of the
Regular Security to the seller, increased by any original issue discount or
market discount previously included in the seller's gross income with respect to
the Regular Security and reduced by amounts included in the stated redemption
price at maturity of the Regular Security that were previously received by the
seller, by any amortized premium and by any recognized losses.
 
     Except as described above with respect to market discount, and except as
provided in this paragraph, any gain or loss on the sale or exchange of a
Regular Security realized by an investor who holds the Regular Security as a
capital asset will be capital gain or loss and will be long-term or short-term
depending on whether the Regular Security has been held for the applicable
holding period (described below). Such gain will be treated as ordinary income
(i) if a Regular Security is held as part of a "conversion transaction" as
defined in Code Section 1258(c), up to the amount of interest that would have
accrued on the Regular Securityholder's net investment in the conversion
transaction at 120% of the appropriate applicable Federal rate under Code
Section 1274(d) in effect at the time the taxpayer entered into the transaction
minus any amount previously treated as ordinary income with respect to any prior
disposition of property that was held as part of such transaction, (ii) in the
case of a non-corporate taxpayer, to the extent such taxpayer has made an
election under Code Section 163(d)(4) to have net capital gains taxed as
investment income at ordinary income rates, or (iii) to the extent that such
gain does not exceed the excess, if any, of (a) the amount that would have been
includible in the gross income of the holder if its yield on such Regular
Security were 110% of the applicable Federal rate as of the date of purchase,
over (b) the amount of income actually includible in the gross income of such
holder with respect to such Regular Security. In addition, gain or loss
recognized from the sale of a Regular Security by certain banks or thrift
institutions will be treated as ordinary income or loss pursuant to Code Section
582(c). Capital gains of non-corporate taxpayers generally are subject to a
lower maximum tax rate (20%) than ordinary income of such taxpayers (39.6%) for
capital assets held for more than one year. The maximum tax rate for
corporations is the same with respect to both ordinary income and capital gains.
 
TAXATION OF OWNERS OF RESIDUAL SECURITIES
 
TAXATION OF REMIC INCOME
 
     Generally, the "daily portions" of REMIC taxable income or net loss will be
includible as ordinary income or loss in determining the federal taxable income
of holders of Residual Securities ("Residual Holders"), and will not be taxed
separately to the REMIC Pool. The daily portions of REMIC taxable income or net
loss of a Residual Holder are determined by allocating the REMIC Pool's taxable
income or net loss for each calendar quarter ratably to each day in such quarter
and by allocating such daily portion among the Residual Holders in proportion to
their respective holdings of Residual Securities in the REMIC Pool on such day.
REMIC taxable income is generally determined in the same manner as the taxable
income of an individual using the accrual method of accounting, except that (i)
the limitations on deductibility of investment interest expense and expenses for
the production of income do not apply, (ii) all bad loans will be deductible as
business bad debts, and (iii) the limitation on the deductibility of interest
and expenses related to tax-exempt income will apply. The REMIC Pool's gross
income includes interest, original issue discount income and market discount
income, if any, on the Mortgage Loans, reduced by amortization of any premium on
the Mortgage Loans, plus income from amortization of issue premium, if any, on
the Regular Securities, plus income on reinvestment of cash flows and reserve
assets, plus any cancellation of indebtedness income upon allocation of realized
losses to the Regular Securities. The REMIC Pool's deductions include interest
and original issue discount expense on the Regular Securities, servicing fees on
the Mortgage Loans, other administrative expenses of the REMIC Pool and realized
losses on the Mortgage Loans. The requirement that Residual Holders report their
pro rata share of taxable
 
                                       96
<PAGE>
income or net loss of the REMIC Pool will continue until there are no Securities
of any class of the related Series outstanding.
 
     The taxable income recognized by a Residual Holder in any taxable year will
be affected by, among other factors, the relationship between the timing of
recognition of interest, original issue discount or market discount income or
amortization of premium with respect to the Mortgage Loans, on the one hand, and
the timing of deductions for interest (including original issue discount) or
income from amortization of issue premium on the Regular Securities, on the
other hand. In the event that an interest in the Mortgage Loans is acquired by
the REMIC Pool at a discount, and one or more of such Mortgage Loans is prepaid,
the prepayment may be used in whole or in part to make distributions in
reduction of principal on the Regular Securities, and (ii) the discount on the
Mortgage Loans which is includible in income may exceed the deduction allowed
upon such distributions on those Regular Securities on account of any unaccrued
original issue discount relating to those Regular Securities. When there is more
than one Class of Regular Securities that distribute principal sequentially,
this mismatching of income and deductions is particularly likely to occur in the
early years following issuance of the Regular Securities when distributions in
reduction of principal are being made in respect of earlier Classes of Regular
Securities to the extent that such Classes are not issued with substantial
discount or are issued at a premium. If taxable income attributable to such a
mismatching is realized, in general, losses would be allowed in later years as
distributions on the later maturing Classes of Regular Securities are made.
Taxable income may also be greater in earlier years than in later years as a
result of the fact that interest expense deductions, expressed as a percentage
of the outstanding principal amount of such a Series of Regular Securities, may
increase over time as distributions in reduction of principal are made on the
lower yielding Classes of Regular Securities, whereas, to the extent the REMIC
Pool consists of fixed rate Mortgage Loans, interest income with respect to any
given Mortgage Loan will remain constant over time as a percentage of the
outstanding principal amount of that loan. Consequently, Residual Holders must
have sufficient other sources of cash to pay any federal, state, or local income
taxes due as a result of such mismatching or unrelated deductions against which
to offset such income, subject to the discussion of "excess inclusions" below
under "--Limitations on Offset or Exemption of REMIC Income." The timing of such
mismatching of income and deductions described in this paragraph, if present
with respect to a Series of Securities, may have a significant adverse effect
upon a Residual Holder's after-tax rate of return. In addition, a Residual
Holder's taxable income during certain periods may exceed the income reflected
by such Residual Holders for such periods in accordance with generally accepted
accounting principles. Investors should consult their own accountants concerning
the accounting treatment of their investment in Residual Securities.
 
BASIS AND LOSSES
 
     The amount of any net loss of the REMIC Pool that may be taken into account
by the Residual Holder is limited to the adjusted basis of the Residual Security
as of the close of the quarter (or time of disposition of the Residual Security,
if earlier), determined without taking into account the net loss for the
quarter. The initial adjusted basis of a purchaser of a Residual Security is the
amount paid for such Residual Security. Such adjusted basis will be increased by
the amount of taxable income of the REMIC Pool reportable by the Residual Holder
and will be decreased (but not below zero), first, by a cash distribution from
the REMIC Pool and, second, by the amount of loss of the REMIC Pool reportable
by the Residual Holder. Any loss that is disallowed on account of this
limitation may be carried over indefinitely with respect to the Residual Holder
as to whom such loss was disallowed and may be used by such Residual Holder only
to offset any income generated by the same REMIC Pool.
 
     A Residual Holder will not be permitted to amortize directly the cost of
its Residual Security as an offset to its share of the taxable income of the
related REMIC Pool. However, the taxable income will not include cash received
by the REMIC Pool that represents a recovery of the REMIC Pool's basis in its
assets. Such recovery of basis by the REMIC Pool will have the effect of
amortization of the issue price of the Residual Securities over their life.
However, in view of the possible acceleration of the income of Residual Holders
described above under "Taxation of REMIC Income", the period of time over which
such issue price is effectively amortized may be longer than the economic life
of the Residual Securities.
 
                                       97
<PAGE>
     A Residual Security may have a negative value if the net present value of
anticipated tax liabilities exceeds the present value of anticipated cash flows.
The REMIC Regulations appear to treat the issue price of such a residual
interest as zero rather than such negative amount for purposes of determining
the REMIC Pool's basis in its assets. The preamble to the REMIC Regulations
states that the Internal Revenue Service may provide future guidance on the
proper tax treatment of payments made by a transferor of such a residual
interest to induce the transferee to acquire the interest, and Residual Holders
should consult their own tax advisors in this regard.
 
     Further, to the extent that the initial adjusted basis of a Residual Holder
(other than an original holder) in the Residual Security is greater than the
corresponding portion of the REMIC Pool's basis in the Mortgage Loans, the
Residual Holder will not recover a portion of such basis until termination of
the REMIC Pool unless future Treasury regulations provide for periodic
adjustments to the REMIC income otherwise reportable by such holder. The REMIC
Regulations currently in effect do not so provide. See "--Treatment of Certain
Items of REMIC Income and Expense--Market Discount" below regarding the basis of
Mortgage Loans to the REMIC Pool and "Sale or Exchange of a Residual Security"
below regarding possible treatment of a loss upon termination of the REMIC Pool
as a capital loss.
 
TREATMENT OF CERTAIN ITEMS OF REMIC INCOME AND EXPENSE
 
     Although it is anticipated that the Trustee will compute REMIC income and
expense in accordance with the Code and applicable regulations, the authorities
regarding the determination of specific items of income and expense are subject
to differing interpretations. The Depositor makes no representation as to the
specific method that will be used for reporting income with respect to the
Mortgage Loans and expenses with respect to the Regular Securities, and
different methods could result in different timing or reporting of taxable
income or net loss to Residual Holders or differences in capital gain versus
ordinary income.
 
     Original Issue Discount and Premium.  Generally, the REMIC Pool's
deductions for original issue discount and income from amortization of issue
premium will be determined in the same manner as original issue discount income
on Regular Securities as described above under "Taxation of Owners of Regular
Securities--Original Issue Discount" and "--Variable Rate Regular Securities",
without regard to the de minimis rule described therein, and "--Premium."
 
     Market Discount.  The REMIC Pool will have market discount income in
respect of Mortgage Loans if, in general, the basis of the REMIC Pool in such
Mortgage Loans is exceeded by their unpaid principal balances. The REMIC Pool's
basis in such Mortgage Loans is generally the fair market value of the Mortgage
Loans immediately after the transfer thereof to the REMIC Pool. The REMIC
Regulations provide that such basis is equal in the aggregate to the issue
prices of all regular and residual interests in the REMIC Pool. The accrued
portion of such market discount would be recognized currently as an item of
ordinary income in a manner similar to original issue discount. Market discount
income generally should accrue in the manner described above under "Taxation of
Owners of Regular Securities--Market Discount."
 
     Premium.  Generally, if the basis of the REMIC Pool in the Mortgage Loans
exceeds the unpaid principal balances thereof, the REMIC Pool will be considered
to have acquired such Mortgage Loans at a premium equal to the amount of such
excess. As stated above, the REMIC Pool's basis in Mortgage Loans is the fair
market value of the Mortgage Loans, based on the aggregate of the issue prices
of the regular and residual interests in the REMIC Pool immediately after the
transfer thereof to the REMIC Pool. In a manner analogous to the discussion
above under "Taxation of Owners of Regular Securities--Premium," a person that
holds a Mortgage Loan as a capital asset under Code Section 1221 may elect under
Code Section 171 to amortize premium on Mortgage Loans originated after
September 27, 1985 under the constant yield method. Amortizable bond premium
will be treated as an offset to interest income on the Mortgage Loans, rather
than as a separate deduction item. Because substantially all of the mortgagors
on the Mortgage Loans are expected to be individuals, Code Section 171 will not
be available for premium on Mortgage Loans originated on or prior to September
27, 1985. Premium with respect to such Mortgage Loans may be deductible in
accordance with a reasonable method regularly employed by the holder thereof.
The allocation of such premium pro rata among principal payments should be
considered a reasonable method; however, the Internal Revenue Service may argue
that such premium should be allocated in a different manner, such as allocating
such premium entirely to the final payment of principal.

LIMITATIONS ON OFFSET OR EXEMPTION OF REMIC INCOME
 
     A portion (or all) of the REMIC taxable income includible in determining
the federal income tax liability of a Residual Holder will be subject to special
treatment. That portion, referred to as the "excess inclusion," is equal to the
excess of REMIC taxable income for the calendar quarter allocable to a Residual
Security over the daily accruals for such quarterly period of (i) 120% of the
long-term applicable Federal rate that would have applied to the Residual
Security (if it were a debt instrument) on the Startup Day under Code Section
1274(d), multiplied by (ii) the adjusted issue price of such Residual Security
at the beginning of such quarterly period. For this purpose, the adjusted issue
price of a Residual Security at the beginning of a quarter is the issue price of
the Residual Security, plus the amount of such daily accruals of REMIC income
described in this paragraph for all prior quarters, decreased by any
distributions made with respect to such Residual Security prior to the beginning
of such quarterly period. Accordingly, the portion of the REMIC Pool's taxable
income that will be treated as excess inclusions will be a larger portion of
such income as the adjusted issue price of the Residual Securities diminishes.
 
     The portion of a Residual Holder's REMIC taxable income consisting of the
excess inclusions generally may not be offset by other deductions, including net
operating loss carryforwards, on such Residual Holder's return. However, net
operating loss carryovers are determined without regard to excess inclusion
income. Further, if the Residual Holder is an organization subject to the tax on
unrelated business income imposed by Code Section 511, the Residual Holder's
excess inclusions will be treated as unrelated business taxable income of such
Residual Holder for purposes of Code Section 511. In addition, REMIC taxable
income is subject to 30% withholding tax with respect to certain persons who are
not U.S. Persons (as defined below under "Tax-Related Restrictions on Transfer
of Residual Securities--Foreign Investors"), and the portion thereof
attributable to excess inclusions is not eligible for any reduction in the rate
of withholding tax (by treaty or otherwise). See "Taxation of Certain Foreign
Investors--Residual Securities" below. Finally, if a real estate investment
trust or a regulated investment company owns a Residual Security, a portion
(allocated under Treasury regulations yet to be issued) of dividends paid by the
real estate investment trust or regulated investment company could not be offset
by net operating losses of its shareholders, would constitute unrelated business
taxable income for tax-exempt shareholders, and would be ineligible for
reduction of withholding to certain persons who are not U.S. Persons. The SBJPA
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 Residual Securities that
have "significant value" within the meaning of the REMIC Regulations, effective
for taxable years beginning after December 31, 1995, except with respect to
Residual Securities continuously held by a thrift institution since November 1,
1995.
 
     In addition, the SBJPA of 1996 provides three rules for determining the
effect of excess inclusions on the alternative minimum taxable income of a
Residual Holder. First, alternative minimum taxable income for a Residual Holder
is determined without regard to the special rule, discussed above, that taxable
income cannot be less than excess inclusions. Second, a Residual Holder's
alternative minimum taxable income for a taxable year cannot be less than the
excess inclusions for the year. Third, the amount of any alternative minimum tax
net operating loss deduction must be computed without regard to any excess
inclusions. These rules are effective for taxable years beginning after December
31, 1986, unless a Residual Holder elects to have such rules apply only to
taxable years beginning after August 20, 1996.
 
TAX-RELATED RESTRICTIONS ON TRANSFER OF RESIDUAL SECURITIES
 
     Disqualified Organizations.  If any legal or beneficial interest in a
Residual Security is transferred to a Disqualified Organization (as defined
below), a tax would be imposed in an amount equal to the product of (i) the
present value of the total anticipated excess inclusions with respect to such
Residual Security for periods after the transfer and (ii) the highest marginal
federal income tax rate applicable to corporations. The REMIC Regulations
provide that the anticipated excess inclusions are based on actual prepayment
experience to the date of the transfer and projected payments based on the
Prepayment Assumption. The present value rate equals the applicable Federal rate
under Code Section 1274(d) as of the date of the transfer for a term ending with
the last calendar quarter in which excess inclusions are expected to accrue.
Such rate is applied to the anticipated excess inclusions from the end of the
remaining calendar quarters in which they arise to the date of the transfer.
Such a tax generally would be imposed on the transferor of the Residual
Security, except that where such transfer is
 
                                       99
<PAGE>
through an agent (including a broker, nominee, or other middleman) for a
Disqualified Organization, the tax would instead be imposed on such agent.
However, a transferor of a Residual Security would in no event be liable for
such tax with respect to a transfer if the transferee furnished to the
transferor an affidavit stating that the transferee is not a Disqualified
Organization and, as of the time of the transfer, the transferor does not have
actual knowledge that such affidavit is false. The tax also may be waived by the
Internal Revenue Service if the Disqualified Organization promptly disposes of
the Residual Security and the transferor pays income tax at the highest
corporate rate on the excess inclusion for the period the Residual Security is
actually held by the Disqualified Organization.
 
     In addition, if a "Pass-Through Entity" (as defined below) has excess
inclusion income with respect to a Residual Security during a taxable year and a
Disqualified Organization is the record holder of an equity interest in such
entity, then a tax is imposed on such entity equal to the product of (i) the
amount of excess inclusions that are allocable to the interest in the
Pass-Through Entity during the period such interest is held by such Disqualified
Organization, and (ii) the highest marginal federal corporate income tax rate.
Such tax would be deductible from the ordinary gross income of the Pass-Through
Entity for the taxable year. The Pass-Through Entity would not be liable for
such tax if it has received an affidavit from such record holder that it is not
a Disqualified Organization or stating such holder's taxpayer identification
number and, during the period such person is the record holder of the Residual
Security, the Pass-Through Entity does not have actual knowledge that such
affidavit is false.
 
     For taxable years beginning on or after January 1, 1998, if an "electing
large partnership" holds a Residual Security, all interests in the electing
large partnership are treated as held by Disqualified Organizations for purposes
of the tax imposed upon a Pass-Through Entity by Section 860E(c) of the Code. An
exception to this tax, otherwise available to a Pass-Through Entity that is
furnished certain affidavits by record holders of interests in the entity and
that does not know such affidavits are false, is not available to an electing
large partnership.
 
     For these purposes, (i) "Disqualified Organization" means the United
States, any state or political subdivision thereof, any foreign government, any
international organization, any agency or instrumentality of any of the
foregoing (provided, that such term does not include an instrumentality if all
of its activities are subject to tax and a majority of its board of directors is
not selected by any such governmental entity), any cooperative organization
furnishing electric energy or providing telephone service or persons in rural
areas as described in Code Section 1381(a)(2)(C), and any organization (other
than a farmers' cooperative described in Code Section 531) that is exempt from
taxation under the Code unless such organization is subject to the tax on
unrelated business income imposed by Code Section 511, (ii) "Pass-Through
Entity" means any regulated investment company, real estate investment trust,
common trust fund, partnership, trust or estate and certain corporations
operating on a cooperative basis. Except as may be provided in Treasury
regulations, any person holding an interest in a Pass-Through Entity as a
nominee for another will, with respect to such interest, be treated as a
Pass-Through Entity, and (iii) an "electing large partnership" means any
partnership having more than 100 members during the preceding tax year (other
than certain service partnerships and commodity pools), which elects to apply
certain simplified reporting provisions under the Code.
 
     The Pooling and Servicing Agreement with respect to a Series will provide
that no legal or beneficial interest in a Residual Security may be transferred
or registered unless (i) the proposed transferee furnished to the transferor and
the Trustee an affidavit providing its taxpayer identification number and
stating that such transferee is the beneficial owner of the Residual Security
and is not a Disqualified Organization and is not purchasing such Residual
Security on behalf of a Disqualified Organization (i.e., as a broker, nominee or
middleman thereof) and (ii) the transferor provides a statement in writing to
the Trustee that it has no actual knowledge that such affidavit is false.
Moreover, the Pooling and Servicing Agreement will provide that any attempted or
purported transfer in violation of these transfer restrictions will be null and
void and will vest no rights in any purported transferee. Each Residual Security
with respect to a Series will bear a legend referring to such restrictions on
transfer, and each Residual Holder will be deemed to have agreed, as a condition
of ownership thereof, to any amendments to the related Pooling and Servicing
Agreement required under the Code or applicable Treasury regulations to
effectuate the foregoing restrictions. Information necessary to compute an
applicable excise tax must be furnished to the Internal Revenue Service and to
the requesting party within 60 days of the request, and the Seller or the
Trustee may charge a fee for computing and providing such information.
 
                                      100
<PAGE>
     Noneconomic Residual Interests.  The REMIC Regulations would disregard
certain transfers of Residual Securities, in which case the transferor would
continue to be treated as the owner of the Residual Securities and thus would
continue to be subject to tax on its allocable portion of the net income of the
REMIC Pool. Under the REMIC Regulations, a transfer of a "noneconomic residual
interest" (as defined below) to a Residual Holder (other than a Residual Holder
who is not a U.S. Person as defined below under "Foreign Investors") is
disregarded for all federal income tax purposes if a significant purpose of the
transferor is to impede the assessment or collection of tax. A residual interest
in a REMIC (including a residual interest with a positive value at issuance) 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 at
least equals the product of the present value of the anticipated excess
inclusions and the highest corporate income tax rate in effect 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 taxes accrue on the anticipated excess inclusions in an amount sufficient
to satisfy the accrued taxes on each excess inclusion. The anticipated excess
inclusions and the present value rate are determined in the same manner as set
forth above under "Disqualified Organizations." The REMIC Regulations explain
that a significant purpose to impede the assessment or collection of tax exists
if the transferor, at the time of the transfer, either knew or should have known
that the transferee would be unwilling or unable to pay taxes due on its share
of the taxable income of the REMIC. A safe harbor is provided if (i) the
transferor conducted, at the time of the transfer, a reasonable investigation of
the financial condition of the transferee and found that the transferee
historically had paid its debts as they came due and found no significant
evidence to indicate that the transferee would not continue to pay its debts as
they came due in the future, and (ii) the transferee represents to the
transferor that it understands that, as the holder of the non-economic residual
interest, the transferee may incur liabilities in excess of any cash flows
generated by the interest and that the transferee intends to pay taxes
associated with holding the residual interest as they become due. The Pooling
and Servicing Agreement with respect to each Series of Certificates will require
the transferee of a Residual Security to certify to the matters in the preceding
sentence as part of the affidavit described above under the heading
"Disqualified Organizations."
 
     Foreign Investors.  The REMIC Regulations provide that the transfer of a
Residual Security that has "tax avoidance potential" to a "foreign person" will
be disregarded for all federal tax purposes. This rule appears intended to apply
to a transferee who is not a "U.S. Person" (as defined below), unless such
transferee's income is effectively connected with the conduct of a trade or
business within the United States. A Residual Security is deemed to have tax
avoidance potential unless, at the time of the transfer, (i) the future value of
expected distributions equals at least 30% of the anticipated excess inclusions
after the transfer, and (ii) the transferor reasonably expects that the
transferee will receive sufficient distributions from the REMIC Pool at or after
the time at which the excess inclusions accrue and prior to the end of the next
succeeding taxable year for the accumulated withholding tax liability to be
paid. If the non-U.S. Person transfers the Residual Security back to a U.S.
Person, the transfer will be disregarded and the foreign transferor will
continue to be treated as the owner unless arrangements are made so that the
transfer does not have the effect of allowing the transferor to avoid tax on
accrued excess inclusions.
 
     The Prospectus Supplement relating to the Certificates of a Series may
provide that a Residual Security may not be purchased by or transferred to any
person that is not a U.S. Person or may describe the circumstances and
restrictions pursuant to which such a transfer may be made. The term "U.S.
Person" means a citizen or resident of the United States, a corporation or
partnership or other entity created or organized in or under the laws of the
United States, any State thereof or the District of Columbia (unless, in the
case of a partnership, Treasury regulations are adopted that provide otherwise),
including an entity treated as a corporation or partnership for federal income
tax purposes, an estate that is subject to U.S. federal income tax regardless of
the source of its income, or, generally, a trust if a court within the United
States is able to exercise primary supervision over the administration of such
trust, and one or more U.S. Persons have the authority to control all
substantial decisions of such trust (or, to the extent provided in applicable
Treasury regulations, certain trusts in existence on August 20, 1996, which are
eligible to elect to be treated as U.S. Persons).
 
SALE OR EXCHANGE OF A RESIDUAL SECURITY
 
     Upon the sale or exchange of a Residual Security, the Residual Holder will
recognize gain or loss equal to the excess, if any, of the amount realized over
the adjusted basis (as described above under "Taxation of Owners of Residual
Securities--Basis and Losses") of such Residual Holder in such Residual Security
at the time of the sale or
 
                                      101
<PAGE>
exchange. In addition to reporting the taxable income of the REMIC Pool, a
Residual Holder will have taxable income to the extent that any cash
distribution to it from the REMIC Pool exceeds such adjusted basis on that
Distribution Date. Such income will be treated as gain from the sale or exchange
of the Residual Holder's Residual Security, in which case, if the Residual
Holder has an adjusted basis in its Residual Security remaining when its
interest in the REMIC Pool terminates, and if it holds such Residual Security as
a capital asset under Code Section 1221, then it will recognize a capital loss
at that time in the amount of such remaining adjusted basis.
 
     Any gain on the sale of a Residual Security will be treated as ordinary
income (i) if a Residual Security is held as part of a "conversion transaction"
as defined in Code Section 1258(c), up to the amount of interest that would have
accrued on the Residual Holder's net investment in the conversion transaction at
120% of the appropriate applicable Federal rate in effect at the time the
taxpayer entered into the transaction minus any amount previously treated as
ordinary income with respect to any prior disposition of property that was held
as a part of such transaction or (ii) in the case of a non-corporate taxpayer,
to the extent such taxpayer has made an election under Code
Section 163(d)(4) to have net capital gains taxed as investment income at
ordinary income rates. In addition, gain or loss recognized from the sale of a
Residual Security by certain banks or thrift institutions will be treated as
ordinary income or loss pursuant to Code Section 582(c).
 
     The Conference Committee Report to the 1986 Act provides that, except as
provided in Treasury regulations yet to be issued, the wash sale rules of Code
Section 1091 will apply to dispositions of Residual Securities where the seller
of the Residual Security, during the period beginning six months before the sale
or disposition of the Residual Security and ending six months after such sale or
disposition, acquires (or enters into any other transaction that results in the
application of Code Section 1091) any residual interest in any REMIC or any
interest in a "taxable mortgage pool" (such as a non-REMIC owner trust) that is
economically comparable to a Residual Security.
 
MARK TO MARKET REGULATIONS
 
     On December 24, 1996, the Internal Revenue Service issued final regulations
(the "Mark to Market Regulations") under Code Section 475 relating to the
requirement that a securities dealer mark to market securities held for sale to
customers. This mark to market requirement applies to all securities of a
dealer, except to the extent that the dealer has specifically identified a
security as held for investment. The Mark to Market Regulations provide that,
for purposes of this mark to market requirement, a Residual Security is not
treated as a security and thus may not be marked to market. The Mark to Market
Regulations apply to all Residual Securities acquired on or after January 4,
1995.
 
TAXES THAT MAY BE IMPOSED ON THE REMIC POOL
 
PROHIBITED TRANSACTIONS
 
     Income from certain transactions by the REMIC Pool, called prohibited
transactions, will not be part of the calculation of income or loss includible
in the federal income tax returns of Residual Holders, but rather will be taxed
directly to the REMIC Pool at a 100% rate. Prohibited transactions generally
include (i) the disposition of a qualified mortgage other than for (a)
substitution within two years of the Startup Day for a defective (including a
defaulted) obligation (or repurchase in lieu of substitution of a defective
(including a defaulted) obligation at any time) or for any qualified mortgage
within three months of the Startup Day, (b) foreclosure, default, or imminent
default of a qualified mortgage, (c) bankruptcy or insolvency of the REMIC Pool,
or (d) a qualified (complete) liquidation, (ii) the receipt of income from
assets that are not the type of mortgages or investments that the REMIC Pool is
permitted to hold, (iii) the receipt of compensation for services, or (iv) the
receipt of gain from disposition of cash flow investments other than pursuant to
a qualified liquidation. Notwithstanding (i) and (iv), it is not a prohibited
transaction to sell REMIC Pool property to prevent a default on Regular
Securities as a result of a default on qualified mortgages or to facilitate a
clean-up call (generally, an optional termination to save administrative costs
when no more than a small percentage of the Securities is outstanding). The
REMIC Regulations indicate that the modification of a Mortgage Loan generally
will not be treated as a disposition if it is occasioned by a default or
reasonably foreseeable default, an assumption of the Mortgage Loan, the waiver
of a due-on-sale or due-on-encumbrance clause, or the conversion of an interest
rate by a mortgagor pursuant to the terms of a convertible adjustable rate
Mortgage Loan.
 
                                      102
<PAGE>
CONTRIBUTIONS TO THE REMIC POOL AFTER THE STARTUP DAY
 
     In general, the REMIC Pool will be subject to a tax at a 100% rate on the
value of any property contributed to the REMIC Pool after the Startup Day.
Exceptions are provided for cash contributions to the REMIC Pool (i) during the
three months following the Startup Day, (ii) made to a qualified reserve fund by
a Residual Holder, (iii) in the nature of a guarantee, (iv) made to facilitate a
qualified liquidation or clean-up call, and (v) as otherwise permitted in
Treasury regulations yet to be issued. It is not anticipated that there will be
any contributions to the REMIC Pool after the Startup Day.
 
NET INCOME FROM FORECLOSURE PROPERTY
 
     The REMIC Pool will be subject of federal income tax at the highest
corporate rate on "net income from foreclosure property", determined by
reference to the rules applicable to real estate investment trusts. Generally,
property acquired by deed in lieu of foreclosure would be treated as
"foreclosure property" until the close of the third calendar year following the
year of acquisition, with a possible extension. Net income from foreclosure
property generally means gain from the sale of a foreclosure property that is
inventory property and gross income from foreclosure property other than
qualifying rents and other qualifying income for a real estate investment trust.
It is not anticipated that the REMIC Pool will have any taxable net income from
foreclosure property.
 
LIQUIDATION OF THE REMIC POOL
 
     If a REMIC Pool adopts a plan of complete liquidation, within the meaning
of Code Section 860F(a)(4)(A)(i), which may be accomplished by designating in
the REMIC Pool's final tax return a date on which such adoption is deemed to
occur, and sells all of its assets (other than cash) within a 90-day period
beginning on such date, the REMIC Pool will not be subject to the prohibited
transaction rules on the sale of its assets, provided that the REMIC Pool
credits or distributes in liquidation all of the sale proceeds plus its cash
(other than amounts retained to meet claims) to holders of Regular Securities
and Residual Holders within the 90-day period.
 
ADMINISTRATIVE MATTERS
 
     The REMIC Pool will be required to maintain its books on a calendar year
basis and to file federal income tax returns for federal income tax purposes in
a manner similar to a partnership. The form for such income tax return is Form
1066, U.S. Real Estate Mortgage Investment Conduit Income Tax Return. The
Trustee will be required to sign the REMIC Pool's returns. Treasury regulations
provide that, except where there is a single Residual Holder for an entire
taxable year, the REMIC Pool will be subject to the procedural and
administrative rules of the Code applicable to partnerships, including the
determination by the Internal Revenue Service of any adjustments to, among other
things, items of REMIC income, gain, loss, deduction, or credit in a unified
administrative proceeding. The Master Servicer will be obligated to act as "tax
matters person", as defined in applicable Treasury regulations, with respect to
the REMIC Pool as agent of the Residual Holder holding the largest percentage
interest in the Residual Securities. If the Code or applicable Treasury
regulations do not permit the Master Servicer to act as tax matters person in
its capacity as agent of such Residual Holder, such Residual Holder or such
other person specified pursuant to Treasury regulations will be required to act
as tax matters person.
 
LIMITATIONS ON DEDUCTION OF CERTAIN EXPENSES
 
     An investor who is an individual, estate, or trust will be subject to
limitation with respect to certain itemized deductions described in Code Section
67, to the extent that such itemized deductions, in the aggregate, do not exceed
2% of the investor's adjusted gross income. In addition, Code Section 68
provides that itemized deductions otherwise allowable for a taxable year of an
individual taxpayer will be reduced by the lesser of (i) 3% of the excess, if
any, of adjusted gross income over $124,500 for 1998 ($62,250 in the case of a
married individual filing a separate return) (as adjusted for inflation for
subsequent years), or (ii) 80% of the amount of itemized deductions otherwise
allowable for such year. In the case of a REMIC Pool, such deductions may
include deductions under Code Section 212 for the Servicing Fee and all
administrative and other expenses relating to the REMIC Pool, or any similar
expenses allocated to the REMIC Pool with respect to a regular interest it holds
in another REMIC. Such investors who hold REMIC Securities either directly or
indirectly through certain pass-through entities may have their pro rata share
of such expenses allocated to them as
 
                                      103
<PAGE>
additional gross income, but may be subject to such limitation on deductions. In
addition, such expenses are not deductible at all for purposes of computing the
alternative minimum tax, and may cause such investors to be subject to
significant additional tax liability. Temporary Treasury regulations provide
that the additional gross income and corresponding amount of expenses generally
are to be allocated entirely to the holders of Residual Securities in the case
of a REMIC Pool that would not qualify as a fixed investment trust in the
absence of a REMIC election. However, such additional gross income and
limitation on deductions will apply to the allocable portion of such expenses to
holders of Regular Securities, as well as holders of Residual Securities, where
such Regular Securities are issued in a manner that is similar to pass-through
certificates in a fixed investment trust. Unless indicated otherwise in the
applicable Prospectus Supplement, all such expenses will be allocable to the
Residual Securities. In general, such allocable portion will be determined based
on the ratio that a REMIC Securityholder's income, determined on a daily basis,
bears to the income of all holders of Regular Securities and Residual Securities
with respect to a REMIC Pool. As a result, individuals, estates or trusts
holding REMIC Securities (either directly or indirectly through a grantor trust,
partnership, S corporation, REMIC, or certain other pass-through entities
described in the foregoing temporary Treasury regulations) may have taxable
income in excess of the interest income at the pass-through rate on Regular
Securities that are issued in a single class or otherwise consistently with
fixed investment trust status or in excess of cash distributions for the related
period on Residual Securities.
 
TAXATION OF CERTAIN FOREIGN INVESTORS
 
REGULAR SECURITIES
 
     Interest, including original issue discount, distributable to Regular
Securityholders who are non-resident aliens, foreign corporations, or other
non-U.S. Persons (as defined below), will be considered "portfolio interest"
and, therefore, generally will not be subject to 30% United States withholding
tax, provided that such non-U.S. Person (i) is not a "10-percent shareholder"
within the meaning of Code Section 871(h)(3)(B) or a controlled foreign
corporation described in Code Section 881(c)(3)(C) and (ii) provides the
Trustee, or the person who would otherwise be required to withhold tax from such
distributions under Code Section 1441 or 1442, with an appropriate statement,
signed under penalties of perjury, identifying the beneficial owner and stating,
among other things, that the beneficial owner of the Regular Security is a
Non-U.S. Person. If such statement, or any other required statement, is not
provided, 30% withholding will apply unless reduced or eliminated pursuant to an
applicable tax treaty or unless the interest on the Regular Security is
effectively connected with the conduct of a trade or business within the United
States by such Non-U.S. Person. In the latter case, such Non-U.S. Person will be
subject to United States federal income tax at regular rates. Investors who are
Non-U.S. Persons should consult their own tax advisors regarding the specific
tax consequences to them of owning a Regular Security. The term "Non-U.S.
Person" means any person who is not a U.S. Person.
 
     The IRS recently issued final regulations (the "New Regulations") which
would provide alternative methods of satisfying the beneficial ownership
certification requirement described above. The New Regulations are effective
January 1, 2000, although valid witholding certificates that are held on
December 31, 1999, remain valid until the earlier of December 31, 2000, or the
due date of expiration of the certificate under the rules as currently in
effect. The New Regulations would require, in the case of Regular Securities
held by a foreign partnership, that (x) the certification described above be
provided by the partners rather than by the foreign partnership and (y) the
partnership provide certain information, including a United States taxpayer
identification number. A look-through rule would apply in the case of tiered
partnerships. Non-U.S. Persons should consult their own tax advisors concerning
the application of the certification requirements in the New Regulations.
 
RESIDUAL SECURITIES
 
     The Conference Committee Report to the 1986 Act indicates that amounts paid
to Residual Holders who are Non-U.S. Persons generally should be treated as
interest for purposes of the 30% (or lower treaty rate) United States
withholding tax. Treasury regulations provide that amount distributed to
Residual Holders may qualify as "portfolio interest", subject to the conditions
described in "Regular Securities" above, but only to the extent that (i) the
Mortgage Loans were issued after July 18, 1984 and (ii) the Trust Estate or
segregated pool of assets therein (as to which a separate REMIC election will be
made), to which the Residual Security relates, consists of obligations issued in
"registered form" within the meaning of Code Section 163(f)(1). Generally,
Mortgage
 
                                      104
<PAGE>
Loans will not be, but regular interests in another REMIC Pool will be,
considered obligations issued in registered form. Furthermore, Residual Holders
will not be entitled to any exemption from the 30% withholding tax (or lower
treaty rate) to the extent of that portion of REMIC taxable income that
constitutes an "excess inclusion." See "Taxation of Owners of Residual
Securities--Limitations on Offset or Exemption of REMIC Income." If the amounts
paid to Residual Holders who are Non-U.S. Persons are effectively connected with
the conduct of a trade or business within the United States by such Non-U.S.
Persons, 30% (or lower treaty rate) withholding will not apply. Instead, the
amounts paid to such Non-U.S. Persons will be subject to United States federal
income tax at regular rates. If 30% (or lower treaty rate) withholding is
applicable, such amounts generally will be taken into account for purposes of
withholding only when paid or otherwise distributed (or when the Residual
Security is disposed of) under rules similar to withholding upon disposition of
debt instruments that have original issue discount. See "Tax-Related
Restrictions on Transfer of Residual Securities--Foreign Investors" above
concerning the disregard of certain transfers having "tax avoidance potential."
Investors who are Non-U.S. Persons should consult their own tax advisors
regarding the specific tax consequences to them of owning Residual Securities.
 
BACKUP WITHHOLDING
 
     Distributions made on the Regular Securities, and proceeds from the sale of
the Regular Securities to or through certain brokers, may be subject to a
"backup" withholding tax under Code Section 3406 of 31% on "reportable payments"
(including interest distributions, original issue discount, and, under certain
circumstances, principal distributions) unless the Regular Holder complies with
certain reporting and/or certification procedures, including the provision of
its taxpayer identification number to the Trustee, its agent or the broker who
effected the sale of the Regular Security, or such Holder is otherwise an exempt
recipient under applicable provisions of the Code. Any amounts to be withheld
from distribution on the Regular Securities would be refunded by the Internal
Revenue Service or allowed as a credit against the Regular Holder's federal
income tax liability. The New Regulations change certain of the rules relating
to certain presumptions currently available relating to information reporting
and backup withholding. Non-U.S. Persons are urged to contact their own tax
advisors regarding the application to them of backup withholding and information
reporting.
 
REPORTING REQUIREMENTS
 
     Reports of accrued interest, original issue discount and information
necessary to compute the accrual of market discount will be made annually to the
Internal Revenue Service and to individuals, estates, non-exempt and
non-charitable trusts, and partnerships who are either holders of record of
Regular Securities or beneficial owners who own Regular Securities through a
broker or middleman as nominee. All brokers, nominees and all other non-exempt
holders of record of Regular Securities (including corporations, non-calendar
year taxpayers, securities or commodities dealers, real estate investment
trusts, investment companies, common trust funds, thrift institutions and
charitable trusts) may request such information for any calendar quarter by
telephone or in writing by contacting the person designated in Internal Revenue
Service Publication 938 with respect to a particular Series of Regular
Securities. Holders through nominees must request such information from the
nominee.
 
     The Internal Revenue Service's Form 1066 has an accompanying Schedule Q,
Quarterly Notice to Residual Interest Holders of REMIC Taxable Income or Net
Loss Allocation. Treasury regulations require that Schedule Q be furnished by
the REMIC Pool to each Residual Holder by the end of the month following the
close of each calendar quarter (41 days after the end of a quarter under
proposed Treasury regulations) in which the REMIC Pool is in existence.
 
     Treasury regulations require that, in addition to the foregoing
requirements, information must be furnished quarterly to Residual Holders,
furnished annually, if applicable, to holders of Regular Securities, and filed
annually with the Internal Revenue Service concerning Code Section 67 expenses
(see "Limitations on Deduction of Certain Expenses" above) allocable to such
holders. Furthermore, under such regulations, information must be furnished
quarterly to Residual Holders, furnished annually to holders of Regular
Securities, and filed annually with the Internal Revenue Service concerning the
percentage of the REMIC Pool's assets meeting the qualified asset tests
described above under "Characterization of Investments in REMIC Securities."

GRANTOR TRUST FUNDS
 
CLASSIFICATION OF GRANTOR TRUST FUNDS
 
     With respect to each Series of Grantor Trust Securities, Cadwalader,
Wickersham & Taft will deliver its opinion to the effect that, assuming
compliance with all provisions of the related Pooling and Servicing Agreement,
the related Grantor Trust Fund will be classified as a grantor trust under
subpart E, part I of subchapter J of the Code and not as a partnership, an
association taxable as a corporation, or a "taxable mortgage pool" within the
meaning of Code Section 7701(i). Accordingly, each holder of a Grantor Trust
Security generally will be treated as the beneficial owner of an undivided
interest in the Mortgage Loans included in the Grantor Trust Fund.
 
STANDARD SECURITIES
 
GENERAL
 
     Where there is no Retained Interest with respect to the Mortgage Loans
underlying the Securities of a Series, and where such Securities are not
designated as "Stripped Securities", the holder of each such Security in such
Series (referred to herein as "Standard Securities") will be treated as the
owner of a pro rata undivided interest in the ordinary income and corpus
portions of the Grantor Trust Fund represented by its Standard Security and will
be considered the beneficial owner of a pro rata undivided interest in each of
the Mortgage Loans, subject to the discussion below under "Recharacterization of
Servicing Fees." Accordingly, the holder of a Standard Security of a particular
Series will be required to report on its federal income tax return its pro rata
share of the entire income from the Mortgage Loans represented by its Standard
Security, including interest at the coupon rate on such Mortgage Loans, original
issue discount (if any), prepayment fees, assumption fees, and late payment
charges received by the Servicer, in accordance with such Securityholder's
method of accounting. A Securityholder generally will be able to deduct its
share of the Servicing Fee and all administrative and other expenses of the
Trust Estate in accordance with its method of accounting, provided that such
amounts are reasonable compensation for services rendered to that Grantor Trust
Fund. However, investors who are individuals, estates or trusts who own
Securities, either directly or indirectly through certain pass-through entities,
will be subject to limitation with respect to certain itemized deductions
described in Code Section 67, including deductions under Code Section 212 for
the Servicing Fee and all such administrative and other expenses of the Grantor
Trust Fund, to the extent that such deductions, in the aggregate, do not exceed
two percent of an investor's adjusted gross income. In addition, Code
Section 68 provides that itemized deductions otherwise allowable for a taxable
year of an individual taxpayer will be reduced by the lesser of (i) 3% of the
excess, if any, of adjusted gross income over $124,500 for 1998 ($62,250 in the
case of a married individual filing a separate return) (in each case, as
adjusted for inflation in subsequent years), or (ii) 80% of the amount of
itemized deductions otherwise allowable for such year. As a result, such
investors holding Standard Securities, directly or indirectly through a
pass-through entity, may have aggregate taxable income in excess of the
aggregate amount of cash received on such Standard Securities with respect to
interest at the pass-through rate or as discount income on such Standard
Securities. In addition, such expenses are not deductible at all for purposes of
computing the alternative minimum tax, and may cause such investors to be
subject to significant additional tax liability. Moreover, where there is
Retained Interest with respect to the Mortgage Loans underlying a Series of
Securities or where the servicing fees are in excess of reasonable servicing
compensation, the transaction will be subject to the application of the
"stripped bond" and "stripped coupon" rules of the Code, as described below
under "Stripped Securities" and "Recharacterization of Servicing Fees",
respectively.
 
TAX STATUS
 
     Cadwalader, Wickersham & Taft has advised the Depositor that:
 
          1. A Standard Security owned by a "domestic building and loan
     association" within the meaning of Code Section 7701(a)(19) will be
     considered to represent "loans. . . secured by an interest in real property
     which is. . . residential real property" within the meaning of Code Section
     7701(a)(19)(C)(v), provided that the real property securing the Mortgage
     Loans represented by that Standard Security is of the type described in
     such section of the Code.
 
                                      106
<PAGE>
          2. A Standard Security owned by a real estate investment trust will be
     considered to represent "real estate assets" within the meaning of Code
     Section 856(c)(4)(A) to the extent that the assets of the related Grantor
     Trust Fund consist of qualified assets, and interest income on such assets
     will be considered "interest on obligations secured by mortgages on real
     property" to such extent within the meaning of Code Section 856(c)(3)(B).
 
          3. A Standard Security owned by a REMIC will be considered to
     represent an "obligation (including any participation or certificate of
     beneficial ownership therein) which is principally secured by an interest
     in real property" within the meaning of Code Section 860G(a)(3)(A) to the
     extent that the assets of the related Grantor Trust Fund consist of
     "qualified mortgages" within the meaning of Code Section 860G(a)(3).
 
          4. A Standard Security owned by a "financial asset securitization
     investment trust" within the meaning of Code Section 860L(a) will be
     considered to represent "permitted assets" within the meaning of Code
     Section 860L(c) to the extent that the assets of related Grantor Trust Fund
     consist of "debt instruments" or other permitted assets within the meaning
     of Code Section 860L(c).
 
          An issue arises as to whether Buydown Loans may be characterized in
     their entirety under the Code provisions cited in clauses 1 and 2 of the
     immediately preceding paragraph or whether the amount qualifying for such
     treatment must be reduced by the amount of the Buydown Funds. There is
     indirect authority supporting treatment of an investment in a Buydown Loan
     as entirely secured by real property if the fair market value of the real
     property securing the loan exceeds the principal amount of the loan at the
     time of issuance or acquisition, as the case may be. There is no assurance
     that the treatment described above is proper. Accordingly, Securityholders
     are urged to consult their own tax advisors concerning the effects of such
     arrangements on the characterization of such Securityholder's investment
     for federal income tax purposes.
 
PREMIUM AND DISCOUNT
 
     Securityholders are advised to consult with their tax advisors as to the
federal income tax treatment of premium and discount arising either upon initial
acquisition of Standard Securities or thereafter.
 
     Premium.  The treatment of premium incurred upon the purchase of a Standard
Security will be determined generally as described above under "REMICs--Taxation
of Owners of Residual Securities--Premium."
 
     Original Issue Discount.  The original issue discount rules of Code Section
1271 through 1275 will be applicable to a Securityholder's interest in those
Mortgage Loans as to which the conditions for the application of those sections
are met. Rules regarding periodic inclusion of original issue discount income
are applicable to mortgages of corporations originated after May 27, 1969,
mortgages of noncorporate mortgagors (other than individuals) originated after
July 1, 1982, and mortgages of individuals originated after March 2, 1984. Under
the OID Regulations, such original issue discount could arise by the charging of
points by the originator of the mortgages in an amount greater than the
statutory de minimis exception, including a payment of points that is currently
deductible by the borrower under applicable Code provisions or, under certain
circumstances, by the presence of "teaser" rates on the Mortgage Loans. See
"Stripped Securities" below regarding original issue discount on Stripped
Securities.
 
     Original issue discount generally must be reported as ordinary gross income
as it accrues under a constant interest method that takes into account the
compounding of interest, in advance of the cash attributable to such income.
Unless indicated otherwise in the applicable Prospectus Supplement, no
prepayment assumption will be assumed for purposes of such accrual. However,
Code Section 1272 provides for a reduction in the amount of original issue
discount includible in the income of a holder of an obligation that acquires the
obligation after its initial issuance at a price greater than the sum of the
original issue price and the previously accrued original issue discount, less
prior payments of principal. Accordingly, if such Mortgage Loans acquired by a
Securityholder are purchased at a price equal to the then unpaid principal
amount of such Mortgage Loans, no original issue discount attributable to the
difference between the issue price and the original principal amount of such
Mortgage Loans (i.e., points) will be includible by such holder.
 
     Market Discount.  Securityholders also will be subject to the market
discount rules to the extent that the conditions for application of those
sections are met. Market discount on the Mortgage Loans will be determined
 
                                      107
<PAGE>
and will be reported as ordinary income generally in the manner described above
under "REMICs--Taxation of Owners of Regular Securities--Market Discount,"
except that the ratable accrual methods described therein will not apply.
Rather, the holder will accrue market discount pro rata over the life of the
Mortgage Loans, unless the constant yield method is elected. Unless indicated
otherwise in the applicable Prospectus Supplement, no prepayment assumption will
be assumed for purposes of such accrual.
 
RECHARACTERIZATION OF SERVICING FEES
 
     If the servicing fees paid to a Servicer were deemed to exceed reasonable
servicing compensation, the amount of such excess would represent neither income
nor a deduction to Securityholders. In this regard, there are no authoritative
guidelines for federal income tax purposes as to either the maximum amount of
servicing compensation that may be considered reasonable in the context of this
or similar transactions or whether, in the case of Standard Securities, the
reasonableness of servicing compensation should be determined on a weighted
average or loan-by-loan basis. If a loan-by-loan basis is appropriate, the
likelihood that such amount would exceed reasonable servicing compensation as to
some of the Mortgage Loans would be increased. Internal Revenue Service guidance
indicates that a servicing fee in excess of reasonable compensation ("excess
servicing") will cause the Mortgage Loans to be treated under the "stripped
bond" rules. Such guidance provides safe harbors for servicing deemed to be
reasonable and requires taxpayers to demonstrate that the value of servicing
fees in excess of such amounts is not greater than the value of the services
provided.
 
     Accordingly, if the Internal Revenue Service's approach is upheld, a
Servicer who receives a servicing fee in excess of such amounts would be viewed
as retaining an ownership interest in a portion of the interest payments on the
Mortgage Loans. Under the rules of Code Section 1286, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from the right to receive some or all of the principal payments on
the obligation would result in treatment of such Mortgage Loans as "stripped
coupons" and "stripped bonds." Subject to the de minimis rule discussed below
under "Stripped Securities", each stripped bond or stripped coupon could be
considered for this purpose as a non-interest bearing obligation issued on the
date of issue of the Standard Securities, and the original issue discount rules
of the Code would apply to the holder thereof. While Securityholders would still
be treated as owners of beneficial interests in a grantor trust for federal
income tax purposes, the corpus of such trust could be viewed as excluding the
portion of the Mortgage Loans the ownership of which is attributed to the
Servicer, or as including such portion as a second class of equitable interest.
Applicable Treasury regulations treat such an arrangement as a fixed investment
trust, since the multiple classes of trust interests should be treated as merely
facilitating direct investments in the trust assets and the existence of
multiple classes of ownership interests is incidental to that purpose. In
general, such a recharacterization should not have any significant effect upon
the timing or amount of income reported by a Securityholder, except that the
income reported by a cash method holder may be slightly accelerated. See
"Stripped Securities" below for a further description of the federal income tax
treatment of stripped bonds and stripped coupons.
 
SALE OR EXCHANGE OF STANDARD SECURITIES
 
     Upon sale or exchange of a Standard Security, a Securityholder will
recognize gain or loss equal to the difference between the amount realized on
the sale and its aggregate adjusted basis in the Mortgage Loans and other assets
represented by the Security. In general, the aggregate adjusted basis will equal
the Securityholder's cost for the Standard Security, exclusive of accrued
interest, increased by the amount of any income previously reported with respect
to the Standard Security and decreased by the amount of any losses previously
reported with respect to the Standard Security and the amount of any
distributions (other than accrued interest) received thereon. Except as provided
above with respect to market discount on any Mortgage Loans, and except for
certain financial institutions subject to the provisions of Code
Section 582(c), any such gain or loss generally would be capital gain or loss if
the Standard Security was held as a capital asset. However, gain on the sale of
a Standard Security will be treated as ordinary income (i) if a Standard
Security is held as part of a "conversion transaction" as defined in Code
Section 1258(c), up to the amount of interest that would have accrued on the
Securityholder's net investment in the conversion transaction at 120% of the
appropriate applicable Federal rate in effect at the time the taxpayer entered
into the transaction minus any amount previously treated as ordinary income with
respect to any prior disposition of property that was held as part of such
transaction or (ii) in the case of a non-corporate taxpayer, to the extent such
taxpayer has made an election under Code Section 163(d)(4) to have net
 
                                      108
<PAGE>
capital gains taxed as investment income at ordinary income rates. Capital gains
of noncorporate taxpayers generally are subject to a lower maximum tax rate
(20%) than ordinary income of such taxpayers (39.6%) for capital assets held for
more than one year. The maximum tax rate for corporations is the same with
respect to both ordinary income and capital gains.
 
STRIPPED SECURITIES
 
GENERAL
 
     Pursuant to Code Section 1286, the separation of ownership of the right to
receive some or all of the principal payments on an obligation from ownership of
the right to receive some or all of the interest payments results in the
creation of "stripped bonds" with respect to principal payments and "stripped
coupons" with respect to interest payments. For purposes of this discussion,
Securities that are subject to those rules will be referred to as "Stripped
Securities." The Securities will be subject to those rules if (i) the Depositor
or any of its affiliates retains (for its own account or for purposes of
resale), in the form of Retained Interest or otherwise, an ownership interest in
a portion of the payments on the Mortgage Loans, (ii) the Depositor or any of
its affiliates is treated as having an ownership interest in the Mortgage Loans
to the extent it is paid (or retains) servicing compensation in an amount
greater than reasonable consideration for servicing the Mortgage Loans (see
"Standard Securities--Recharacterization of Servicing Fees" above), and (iii) a
Class of Securities are issued in two or more Classes or Subclasses representing
the right to non-pro-rata percentages of the interest and principal payments on
the Mortgage Loans.
 
     In general, a holder of a Stripped Security will be considered to own
"stripped bonds" with respect to its pro rata share of all or a portion of the
principal payments on each Mortgage Loan and/or "stripped coupons" with respect
to its pro rata share of all or a portion of the interest payments on each
Mortgage Loan, including the Stripped Security's allocable share of the
servicing fees paid to a Servicer, to the extent that such fees represent
reasonable compensation for services rendered. See the discussion above under
"Standard Securities--Recharacterization of Servicing Fees." Although not free
from doubt, for purposes of reporting to Stripped Securityholders, the servicing
fees will be allocated to the classes of Stripped Securities in proportion to
the distributions to such Classes for the related period or periods. The holder
of a Stripped Security generally will be entitled to a deduction each year in
respect of the servicing fees, as described above under "Standard
Securities--General," subject to the limitation described therein.
 
     Code Section 1286 treats a stripped bond or a stripped coupon generally as
an obligation issued on the date that such stripped interest is purchased.
Although the treatment of Stripped Securities for federal income tax purposes is
not clear in certain respects, particularly where such Stripped Securities are
issued with respect to a Mortgage Pool containing variable-rate Mortgage Loans,
the Depositor has been advised by counsel that (i) the Grantor Trust Fund will
be treated as a grantor trust under subpart E, Part I of subchapter J of the
Code and not as an association taxable as a corporation or a "taxable mortgage
pool" within the meaning of Code Section 7701(i), and (ii) each Stripped
Security should be treated as a single installment obligation for purposes of
calculating original issue discount and gain or loss on disposition. This
treatment is based on the interrelationship of Code Section 1286, Code Sections
1272 through 1275, and the OID Regulations. Although it is possible that
computations with respect to Stripped Securities could be made in one of the
ways described below under "Possible Alternative Characterizations," the OID
Regulations state, in general, that two or more debt instruments issued by a
single issuer to a single investor in a single transaction should be treated as
a single debt instrument. Accordingly, for original issue discount purposes, all
payments on any Stripped Securities should be aggregated and treated as though
they were made on a single debt instrument. The Pooling and Servicing Agreement
will require that the Trustee make and report all computations described below
using this aggregate approach, unless substantial legal authority requires
otherwise.
 
     Furthermore, Treasury regulations provide for treatment of a Stripped
Security as a single debt instrument issued on the date it is purchased for
purposes of calculating any original issue discount. In addition, under such
regulations, a Stripped Security that represents a right to payments of both
interest and principal may be viewed either as issued with original issue
discount or market discount (as described below), at a de minimis original issue
discount, or, presumably, at a premium. This treatment indicates that the
interest component of such a Stripped Security would be treated as qualified
stated interest under the OID Regulations, assuming it is not an
 
                                      109
<PAGE>
interest-only or super-premium Stripped Security. Further, these regulations
provide that the purchaser of such a Stripped Security will be required to
account for any discount as market discount rather than original issue discount
if either (i) the initial discount with respect to the Stripped Security was
treated as zero under the de minimis rule, or (ii) no more than 100 basis points
in excess of reasonable servicing is stripped off the related Mortgage Loans.
Any such market discount would be reportable as described above under
"REMICs--Taxation of Owners of Regular Securities--Market Discount," without
regard to the de minimis rule therein, assuming that a prepayment assumption is
employed in such computation.
 
STATUS OF STRIPPED SECURITIES
 
     No specific legal authority exists as to whether the character of the
Stripped Securities, for federal income tax purposes, will be the same as that
of the Mortgage Loans. Although the issue is not free from doubt, counsel has
advised the Depositor that Stripped Securities owned by applicable holders
should be considered to represent "real estate assets" within the meaning of
Code Section 856(c)(4)(A), "obligation[s]. . . principally secured by an
interest in real property" within the meaning of Code Section 860G(a)(3)(A), and
"loans. . . secured by an interest in real property" within the meaning of Code
Section 7701(a)(19)(C)(v), and interest (including original issue discount)
income attributable to Stripped Securities should be considered to represent
"interest on obligations secured by mortgages on real property" within the
meaning of Code Section 856(c)(3)(B), provided that in each case the Mortgage
Loans and interest on such Mortgage Loans qualify for such treatment. The
application of such Code provisions to Buydown Loans is uncertain. See "Standard
Securities--Tax Status" above.
 
TAXATION OF STRIPPED SECURITIES
 
     Original Issue Discount.  Except as described above under "General," each
Stripped Security will be considered to have been issued at an original issue
discount for federal income tax purposes. Original issue discount with respect
to a Stripped Security must be included in ordinary income as it accrues, in
accordance with a constant yield method that takes into account the compounding
of interest, which may be prior to the receipt of the cash attributable to such
income. Based in part on the issue discount required to be included in the
income of a holder of a Stripped Security (referred to in this discussion as a
"Stripped Securityholder") in any taxable year likely will be computed generally
as described above under "REMICs--Taxation of Owner of Regular
Securities--Original Issue Discount" and "--Variable Rate Regular Securities."
However, with the apparent exception of a Stripped Security qualifying as a
market discount obligation as described above under "--General," the issue price
of a Stripped Security will be the purchase price paid by each holder thereof,
and the stated redemption price at maturity will include the aggregate amount of
the payments to be made on the Stripped Security to such Securityholder,
presumably under the Prepayment Assumption, other than qualified stated
interest.
 
     If the Mortgage Loans prepay at a rate either faster or slower than that
under the Prepayment Assumption, a Securityholder's recognition of original
issue discount will be either accelerated or decelerated and the amount of such
original issue discount will be either increased or decreased depending on the
relative interests in principal and interest on each Mortgage Loan represented
by such Securityholder's Stripped Security. While the matter is not free from
doubt, the holder of a Stripped Security should be entitled in the year that it
becomes certain (assuming no further prepayments) that the holder will not
recover a portion of its adjusted basis in such Stripped Security to recognize a
loss (which may be a capital loss) equal to such portion of unrecoverable basis.
 
     As an alternative to the method described above, the fact that some or all
of the interest payments with respect to the Stripped Securities will not be
made if the Mortgage Loans are prepaid could lead to the interpretation that
such interest payments are "contingent" within the meaning of the OID
Regulations. The OID Regulations, as they relate to the treatment of contingent
interest, are by their terms not applicable to prepayable securities such as the
Stripped Securities. However, if final regulations dealing with contingent
interest with respect to the Stripped Securities apply the same principles as
the OID Regulations, such regulations may lead to different timing of income
inclusion that would be the case under the OID Regulations. Furthermore,
application of such principles could lead to the characterization of gain on the
sale of contingent interest Stripped Securities as ordinary income. Investors
should consult their tax advisors regarding the appropriate tax treatment of
Stripped Securities.
 
                                      110
<PAGE>
     Sale or Exchange of Stripped Securities.  Sale or exchange of a Stripped
Security prior to its maturity will result in gain or loss equal to the
difference, if any, between the amount received and the Securityholder's
adjusted basis in such Stripped Security, as described above under
"REMICs--Taxation of Owners of Regular Securities--Sale or Exchange of Regular
Securities." To the extent that a subsequent purchaser's purchase price is
exceeded by the remaining payments on the Stripped Securities, such subsequent
purchaser will be required for federal income tax purposes to accrue and report
such excess as if it were original issue discount in the manner described above.
It is not clear for this purpose whether the assumed prepayment rate that is to
be used in the case of a Securityholder other than an original Securityholder
should be the Prepayment Assumption or a new rate based on the circumstances at
the date of subsequent purchase.
 
     Purchase of More Than One Class of Stripped Securities.  When an investor
purchases more than one Class of Stripped Securities, it is currently unclear
whether for federal income tax purposes such Classes of Stripped Securities
should be treated separately or aggregated for purposes of the rules described
above.
 
     Possible Alternative Characterization.  The characterizations of the
Stripped Securities discussed above are not the only possible interpretations of
the applicable Code provisions. For example, the Securityholder may be treated
as the owner of (i) one installment obligation consisting of such Stripped
Security's pro rata share of the payments attributable to principal on each
Mortgage Loan and a second installment obligation consisting of such Stripped
Security's pro rata share of the payments attributable to interest on each
Mortgage Loan, (ii) as many stripped bonds or stripped coupons as there are
scheduled payments of principal and/or interest on each Mortgage Loan, or (iii)
a separate installment obligation for each Mortgage Loan, representing the
Stripped Security's pro rata share of payments of principal and/or interest to
be made with respect thereto. Alternatively, the holder of one or more Classes
of Stripped Securities may be treated as the owner of a pro rata fractional
undivided interest in each Mortgage Loan to the extent that such Stripped
Security, or Classes of Stripped Securities in the aggregate, represent the same
pro rata portion of principal and interest on each such Mortgage Loan, and a
stripped bond or stripped coupon (as the case may be), treated as an installment
obligation or contingent payment obligation, as to the remainder. Treasury
regulations regarding original issue discount on stripped obligations make the
foregoing interpretations less likely to be applicable. The preamble to such
regulations states that they are premised on the assumption that an aggregation
approach is appropriate for determining whether original issue discount on a
stripped bond or stripped coupon is de minimis, and solicits comments on
appropriate rules for aggregating stripped bonds and stripped coupons under Code
Section 1286.
 
     Because of these possible varying characterizations of Stripped Securities
and the resultant differing treatment of income recognition, Securityholders are
urged to consult their own tax advisors regarding the proper treatment of
Stripped Securities for federal income tax purposes.
 
REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
     The Trustee will furnish, within a reasonable time after the end of each
calendar year, to each Securityholder at any time during such year, such
information (prepared on the basis described above) as is necessary to enable
such Securityholder to prepare its federal income tax returns. Such information
will include the amount of original issue discount accrued on Securities held by
persons other than Securityholders exempted from the reporting requirements.
However, the amount required to be reported by the Trustee may not be equal to
the proper amount of original issue discount required to be reported as taxable
income by a Securityholder, other than an original Securityholder that purchased
at the issue price. In particular, in the case of Stripped Securities, unless
provided otherwise in the applicable Prospectus Supplement, such reporting will
be based upon a representative initial offering price of each Class of Stripped
Securities. The Trustee will also file such original issue discount information
with the Internal Revenue Service. If a Securityholder fails to supply an
accurate taxpayer identification number or if the Secretary of the Treasury
determines that a Securityholder has not reported all interest and dividend
income required to be shown on his federal income tax return, 31% backup
withholding may be required in respect of any reportable payments, as described
above under "REMICs--Backup Withholding."

TAXATION OF CERTAIN FOREIGN INVESTORS
 
     To the extent that a Security evidences ownership in Mortgage Loans that
are issued on or before July 18, 1984, interest or original issue discount paid
by the person required to withhold tax under Code Section 1441 or 1442 to
nonresident aliens, foreign corporations, or other Non-U.S. persons generally
will be subject to 30% United States withholding tax, or such lower rate as may
be provided for interest by an applicable tax treaty. Accrued original issue
discount recognized by the Securityholder on the sale or exchange of such a
Security also will be subject to federal income tax at the same rate.
 
     Treasury regulations provide that interest or original issue discount paid
by the Trustee or other withholding agent to a Non-U.S. Person evidencing
ownership interest in Mortgage Loans issued after July 18, 1984 will be
"portfolio interest" and will be treated in the manner, and such persons will be
subject to the same certification requirements, described above under
"REMICs--Taxation of Certain Foreign Investors--Regular Securities."
 
PARTNERSHIP TRUST FUNDS
 
CLASSIFICATION OF PARTNERSHIP TRUST FUNDS
 
     With respect to each Series of Partnership Securities or Debt Securities,
Cadwalader, Wickersham & Taft will deliver its opinion that the Trust Fund will
not be a taxable mortgage pool or an association (or 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 related Pooling
and Servicing Agreement and related documents will be complied with, and on
counsel's conclusion 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.
 
CHARACTERIZATION OF INVESTMENTS IN PARTNERSHIP SECURITIES AND DEBT SECURITIES
 
     For federal income tax purposes, (i) Partnership Securities and Debt
Securities held by a thrift institution taxed as a domestic building and loan
association will not constitute "loans . . . secured by an interest in real
property which is. . . residential real property" within the meaning of Code
Section 7701(a)(19)(C)(v) and (ii) interest on Debt Securities held by a real
estate investment trust will not be treated as "interest on obligations secured
by mortgages on real property or on interests in real property" within the
meaning of Code Section 856(c)(3)(B), and Debt Securities held by a real estate
investment trust will not constitute "real estate assets" within the meaning of
Code Section 856(c)(4)(A), but Partnership Securities held by a real estate
investment trust will qualify under those sections based on the real estate
investments trust's proportionate interest in the assets of the Partnership
Trust Fund based on capital accounts.
 
TAXATION OF DEBT SECURITYHOLDERS
 
TREATMENT OF THE DEBT SECURITIES AS INDEBTEDNESS
 
     The Depositor will agree, and the Securityholders will agree by their
purchase of Debt Securities, to treat the Debt Securities as debt for federal
income tax purposes. No regulations, published rulings, or judicial decisions
exist that discuss the characterization for federal income tax purposes of
securities with terms substantially the same as the Debt Securities. However,
with respect to each Series of Debt Securities, Cadwalader, Wickersham & Taft
will deliver its opinion that the Debt Securities will be classified as
indebtedness for federal income tax purposes. The discussion below assumes this
characterization of the Debt Securities is correct.
 
     If, contrary to the opinion of counsel, the IRS successfully asserted that
the Debt Securities were not debt for federal income tax purposes, the Debt
Securities might be treated as equity interests in the Partnership Trust, and
the timing and amount of income allocable to holders of such Debt Securities may
be different than as described in the following paragraph.
 
     Debt Securities generally will be subject to the same rules of taxation as
Regular Securities issued by a REMIC, as described above, except that
(i) income reportable on Debt Securities is not required to be reported under
the accrual method unless the holder otherwise uses the accrual method and
(ii) the special rule treating a portion of the gain on sale or exchange of a
Regular Security as ordinary income is inapplicable to Debt Securities. See
"REMICs--Taxation of Owners of Regular Securities" and "--Sale or Exchange of
Regular Securities."
 
                                      112
<PAGE>
TAXATION OF OWNERS OF PARTNERSHIP SECURITIES
 
TREATMENT OF THE PARTNERSHIP TRUST FUND AS A PARTNERSHIP
 
     If so specified in the applicable Prospectus Supplement, the Depositor will
agree, and the Securityholders will agree by their purchase of Securities, to
treat the Partnership Trust Fund (i) 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
Partnership Trust Fund, the partners of the partnership being the
Securityholders (including the Depositor), and the Debt Securities (if any)
being debt of the partnership or (ii) if a single beneficial owner owns all of
the Partnership Securities in a Trust Fund, the Trust Fund will be ignored for
federal income tax purposes and the assets and Debt Securities of the Trust Fund
will be treated as assets and indebtedness of such owner.
 
     A variety of alternative characterizations are possible. For example,
because one or more of the classes of Partnership Securities have certain
features characteristic of debt, the Partnership Securities might be considered
debt of the Depositor or the Partnership Trust Fund. Any such characterization
would not result in materially adverse tax consequences to Securityholders as
compared to the consequences from treatment of the Partnership Securities as
equity in a partnership, described below. The following discussion assumes that
the Partnership Securities represent equity interests in a partnership.
 
PARTNERSHIP TAXATION
 
     As a partnership, the Partnership Trust Fund will not be subject to federal
income tax. Rather, each Securityholder will be required to separately take into
account such holder's allocated share of income, gains, losses, deductions and
credits of the Partnership Trust Fund. It is anticipated that the Partnership
Trust Fund's income will consist primarily of interest earned on the Mortgage
Loans (including appropriate adjustments for market discount, original issue
discount and bond premium) as described above under "--Grantor Trust Funds--
Standard Securities--General," and "--Premium and Discount") and any gain upon
collection or disposition of Mortgage Loans. The Partnership Trust Fund's
deductions will consist primarily of interest accruing with respect to the Debt
Securities, servicing and other fees, and losses or deductions upon collection
or disposition of Debt Securities.
 
     The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (here, the
Pooling and Servicing Agreement and related documents). The Pooling and
Servicing Agreement will provide, in general, that the Securityholders will be
allocated taxable income of the Partnership Trust Fund for each Due Period equal
to the sum of (i) the interest that accrues on the Partnership Securities in
accordance with their terms for such Due Period, including interest accruing at
the applicable pass-through rate for such Due Period and interest on amounts
previously due on the Partnership Securities but not yet distributed; (ii) any
Partnership Trust Fund income attributable to discount on the Mortgage Loans
that corresponds to any excess of the principal amount of the Partnership
Securities over their initial issue price; and (iii) any other amounts of income
payable to the Securityholders for such Due Period. Such allocation will be
reduced by any amortization by the Partnership Trust Fund of premium on Mortgage
Loans that corresponds to any excess of the issue price of Partnership
Securities over their principal amount. All remaining taxable income or net loss
of the Partnership Trust Fund will be allocated to the Depositor. Based on the
economic arrangement of the parties, this approach for allocating Partnership
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 Securityholders. Moreover, even under the
foregoing method of allocation, Securityholders 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 Partnership Securities on the accrual basis and Securityholders
may become liable for taxes on Partnership Trust Fund income even if they have
not received cash from the Partnership Trust Fund to pay such taxes.
 
     All of the taxable income allocated to a Securityholder 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.
 
                                      113
<PAGE>
     A share of expenses of the Partnership Trust Fund (including fees of the
Master Servicer but not interest expense) allocable to an individual, estate or
trust Securityholder would be miscellaneous itemized deductions subject to the
limitations described above under "--Grantor Trust Funds--Standard
Securities--General." Accordingly, 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 Partnership Trust Fund.
 
     Discount income or premium amortization with respect to each Mortgage Loan
would be calculated in a manner similar to the description above under
"--Grantor Trust Funds--Standard Securities--General" and "--Premium and
Discount." Notwithstanding such description, it is intended that the Partnership
Trust Fund will make all tax calculations relating to income and allocations to
Securityholders on an aggregate basis with respect to all Mortgage Loans held by
the Partnership Trust Fund rather than on a Mortgage Loan-by-Mortgage Loan
basis. If the IRS were to require that such calculations be made separately for
each Mortgage Loan, the Partnership Trust Fund might be required to incur
additional expense, but it is believed that there would not be a material
adverse effect on Securityholders.
 
DISCOUNT AND PREMIUM
 
     Unless indicated otherwise in the applicable Prospectus Supplement, it is
not anticipated that the Mortgage Loans will have been issued with original
issue discount and, therefore, the Partnership Trust Fund should not have
original issue discount income. However, the purchase price paid by the
Partnership Trust Fund for the Mortgage Loans may be greater or less than the
remaining principal balance of the Mortgage Loans at the time of purchase. If
so, the Mortgage Loans will have been acquired at a premium or discount, as the
case may be. See "Grantor Trust Funds--Standard Securities--Premium and
Discount." (As indicated above, the Partnership Trust Fund will make this
calculation on an aggregate basis, but might be required to recompute it on a
Mortgage Loan-by-Mortgage Loan basis).
 
     If the Partnership Trust Fund acquires the Mortgage Loans at a market
discount or premium, the Partnership Trust Fund will elect to include any such
discount in income currently as it accrues over the life of the Mortgage Loans
or to offset any such premium against interest income on the Mortgage Loans. As
indicated above, a portion of such market discount income or premium deduction
may be allocated to Securityholders.
 
SECTION 708 TERMINATION
 
     Under Section 708 of the Code, the Partnership Trust Fund will be deemed to
terminate for federal income tax purposes if 50% or more of the capital and
profits interests in the Partnership Trust Fund are sold or exchanged within a
12-month period. Such a termination would cause a deemed contribution of the
assets of a Partnership Trust Fund (the "old partnership") to a new Partnership
Trust Fund (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. The Partnership Trust Fund will not comply with certain technical
requirements that might apply when such a constructive termination occurs. As a
result, the Partnership Trust Fund may be subject to certain tax penalties and
may incur additional expenses if it is required to comply with those
requirements. Furthermore, the Partnership Trust Fund might not be able to
comply due to lack of data.
 
DISPOSITION OF SECURITIES
 
     Generally, capital gain or loss will be recognized on a sale of Partnership
Securities in an amount equal to the difference between the amount realized and
the seller's tax basis in the Partnership Securities sold. A Securityholder's
tax basis in a Partnership Security will generally equal the holder's cost
increased by the holder's share of Partnership Trust Fund income (includible in
income) and decreased by any distributions received with respect to such
Partnership Security. In addition, both the tax basis in the Partnership
Securities and the amount realized on a sale of a Partnership Security would
include the holder's share of the Debt Securities and other liabilities of the
Partnership Trust Fund. A holder acquiring Partnership Securities at different
prices may be required to maintain a single aggregate adjusted tax basis in such
Partnership Securities, and, upon sale or other disposition of some of the
Partnership Securities, allocate a portion of such aggregate tax basis to the
Partnership Securities sold (rather than maintaining a separate tax basis in
each Partnership Security for purposes of computing gain or loss on a sale of
that Partnership Security).
 
                                      114
<PAGE>
     Any gain on the sale of a Partnership Security attributable to the holder's
share of unrecognized accrued market discount on the Mortgage Loans would
generally be treated as ordinary income to the holder and would give rise to
special tax reporting requirements. The Partnership Trust Fund does not expect
to have any other assets that would give rise to such special reporting
considerations. Thus, to avoid those special reporting requirements, the
Partnership Trust Fund will elect to include market discount in income as it
accrues.
 
     If a Securityholder is required to recognize an aggregate amount of income
(not including income attributable to disallowed itemized deductions described
above) over the life of the Partnership Securities that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Partnership Securities.
 
ALLOCATIONS BETWEEN TRANSFERORS AND TRANSFEREES
 
     In general, the Partnership Trust Fund's taxable income and losses will be
determined each Due Period and the tax items for a particular Due Period will be
apportioned among the Securityholders in proportion to the principal amount of
Partnership Securities owned by them as of the close of the last day of such Due
Period. As a result, a holder purchasing Partnership Securities 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 Due Period convention may not be permitted by existing
regulations. If a Due Period convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Partnership Trust Fund might be reallocated among the Securityholders.
The Depositor will be authorized to revise the Partnership Trust Fund's method
of allocation between transferors and transferees to conform to a method
permitted by future regulations.
 
SECTION 731 DISTRIBUTIONS
 
     In the case of any distribution to a Securityholder, no gain will be
recognized to that Securityholder to the extent that the amount of any money
distributed with respect to such Security exceeds the adjusted basis of such
Securityholder's interest in the Security. To the extent that the amount of
money distributed exceeds such Securityholder's adjusted basis, gain will be
currently recognized. In the case of any distribution to a Securityholder, no
loss will be recognized except upon a distribution in liquidation of a
Securityholder's interest. Any gain or loss recognized by a Securityholder will
be capital gain or loss.
 
SECTION 754 ELECTION
 
     In the event that a Securityholder sells its Partnership Securities at a
profit (loss), the purchasing Securityholder will have a higher (lower) basis in
the Partnership Securities than the selling Securityholder had. The tax basis of
the Partnership Trust Fund's assets would not be adjusted to reflect that higher
(or lower) basis unless the Partnership 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 Partnership Trust
Fund will not make such election. As a result, Securityholders might be
allocated a greater or lesser amount of Partnership Trust Fund income than would
be appropriate based on their own purchase price for Partnership Securities.
 
ADMINISTRATIVE MATTERS
 
     The Trustee is required to keep or have kept complete and accurate books of
the Partnership Trust Fund. Such books will be maintained for financial
reporting and tax purposes on an accrual basis and the fiscal year of the
Partnership 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 Partnership Trust Fund and will report each Securityholder's
allocable share of items of Partnership Trust Fund income and expense to holders
and the IRS on Schedule K-1. The Trustee will provide the Schedule K-1
information to nominees that fail to provide the Partnership Trust Fund with the
information statement described below and such nominees will be required to
forward such information to the beneficial owners of the Partnership Securities.
Generally, holders must file tax returns that are consistent with the
information return filed by the Partnership Trust Fund or be subject to
penalties unless the holder notifies the IRS of all such inconsistencies.
 
                                      115
<PAGE>
     Under Section 6031 of the Code, any person that holds Partnership
Securities as a nominee at any time during a calendar year is required to
furnish the Partnership Trust Fund with a statement containing certain
information on the nominee, the beneficial owners and the Partnership Securities
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 Partnership Securities
that were held, bought or sold on behalf of such person throughout the year. In
addition, brokers and financial institutions that hold Partnership Securities
through a nominee are required to furnish directly to the Trustee information as
to themselves and their ownership of Partnership Securities. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Partnership Trust Fund. The information
referred to above for any calendar year must be furnished to the Partnership
Trust Fund on or before the following January 31. Nominees, brokers and
financial institutions that fail to provide the Partnership Trust Fund with the
information described above may be subject to penalties.
 
     The Depositor will be designated as the tax matters partner in the Pooling
and Servicing Agreement and, as such, will be responsible for representing the
Securityholders in any dispute with the IRS. The Code provides for
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 until three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the Partnership Trust Fund by the appropriate taxing
authorities could result in an adjustment of the returns of the Securityholders,
and, under certain circumstances, a Securityholder may be precluded from
separately litigating a proposed adjustment to the items of the Partnership
Trust Fund. An adjustment could also result in an audit of a Securityholder's
returns and adjustments of items not related to the income and losses of the
Partnership Trust Fund.
 
TAX CONSEQUENCES TO FOREIGN SECURITYHOLDERS
 
     It is not clear whether the Partnership 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. However, for taxable years of a Partnership Trust Fund
commencing on or after January 1, 1998, securityholders who are Non-U.S. Persons
would in any event not be treated as engaged in a trade or business in the
United States if holding such Security (or other investing or trading in stock
or securities for the Holder's own account) is the only activity of the
securityholder within the United States and the securityholder is not a dealer
in securities. Accordingly, such securityholders will not be subject to
withholding tax pursuant to Section 1446 of the Code, at a rate of 35% for
Non-U.S. Persons that are taxable as corporations and 39.6% for all other
foreign holders. The Prospectus Supplement for an applicable Series will
describe whether an exception to the 30% United States withholding tax on
interest may apply to securityholders.
 
BACKUP WITHHOLDING
 
     Distributions made on the Partnership Securities and proceeds from the sale
of the Partnership Securities will be subject to a "backup" withholding tax of
31% if, in general, the Securityholder fails to comply with certain
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the Code.
 
     THE FEDERAL TAX DISCUSSIONS SET FORTH ABOVE ARE INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A SECURITYHOLDER'S
PARTICULAR TAX SITUATION. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX
ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP
AND DISPOSITION OF REMIC SECURITIES, GRANTOR TRUST SECURITIES, PARTNERSHIP
SECURITIES AND DEBT SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE,
LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL
OR OTHER TAX LAWS.

<PAGE>
                        STATE AND OTHER TAX CONSEQUENCES
 
     In addition to the federal income tax consequences described in "Certain
Federal Income Tax Consequences," potential investors should consider the state
and local tax consequences of the acquisition, ownership, and disposition of the
Securities offered hereunder. State tax law may differ substantially from the
corresponding federal tax law, and the discussion above does not purport to
describe any aspect of the tax laws of any state or other jurisdiction.
Therefore, prospective investors should consult their own tax advisors with
respect to the various tax consequences of investments in the Securities offered
hereunder.
 
                              ERISA CONSIDERATIONS
 
     Title I of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and Section 4975 of the Code impose certain requirements on
retirement plans and on certain other employee benefit plans and arrangements
(including for this purpose individual retirement accounts and annuities and
Keogh plans) which are subject thereto and on bank collective investment funds
and insurance company general and separate accounts in which such plans,
accounts or arrangements are invested (all of which are hereinafter referred to
as "Plans") and on persons who are fiduciaries with respect to such Plans.
Certain employee benefit plans, such as governmental plans (as defined in
Section 3(32) of ERISA), and, if no election has been made under Section 410(d)
of the Code, church plans (as defined in Section 3(33) of ERISA), are not
subject to the ERISA requirements discussed herein. Accordingly, assets of such
plans may be invested in Securities without regard to the ERISA considerations
described below, subject to the provisions of applicable federal, state and
local law. Any such plan which is qualified and exempt from taxation under
Sections 401(a) and 501(a) of the Code, however, is subject to the prohibited
transaction rules set forth in Section 503 of the Code.
 
     In addition to the imposition of general fiduciary requirements, including
those of investment prudence and diversification and the requirement that a
Plan's investment be made in accordance with the documents governing the Plan,
Section 406(a) of ERISA and Section 4975(c)(1)(A), (B), (C) and (D) of the Code
prohibit a broad range of transactions involving assets of a Plan and persons
("Parties in Interest" within the meaning of Section 3(14) of ERISA and
"Disqualified Persons" within the meaning of Section 4975(e)(2) of the Code,
collectively referred to as "Parties in Interest") who have certain specified
relationships to the Plan. In addition, Section 406(b) of ERISA and Section
4975(c)(1)(E) and (F) of the Code impose certain prohibitions on Parties in
Interest who are fiduciaries with respect to the Plan. Certain Parties in
Interest that participate in a prohibited transaction may be subject to a
penalty imposed under Section 502(i) of ERISA or an excise tax pursuant to
Sections 4975(a) and (b) of the Code, unless a statutory or administrative
exemption is available.
 
     Certain transactions involving a Trust Fund might be deemed to constitute
prohibited transactions under ERISA and Section 4975 of the Code with respect to
a Plan that purchases Securities if the Residential Loans, Agency Securities,
Mortgage Securities and other assets included in such Trust Fund are deemed to
be assets of the Plan. The U.S. Department of Labor (the "DOL") has promulgated
regulations at 29 C.F.R. Section 2510.3-101 (the "DOL Regulations") defining the
term "plan assets" for purposes of applying the general fiduciary responsibility
provisions of ERISA and the prohibited transaction provisions of ERISA and the
Code. Under the DOL Regulations, generally, when a Plan acquires an equity
interest in an entity (such as a Trust Fund), the Plan's assets include the
investment in the entity and an undivided interest in each of the underlying
assets of the entity, unless certain exceptions not applicable here apply, or
unless the equity participation in the entity by "Benefit Plan Investors" is not
significant. For this purpose, in general, equity participation is considered
"significant" on any date if 25% or more of the value of any class of equity
interests is held by "Benefit Plan Investors", which include Plans, as well as
any "employee benefit plan" (as defined in Section 3(3) of ERISA) which is not
subject to Title I of ERISA, such as governmental plans (as defined in Section
3(32) of ERISA) and church plans (as defined in Section 3(33) of ERISA) which
have not made an election under Section 410(d) of the Code, and any entity whose
underlying assets include plan assets by reason of a Plan's investment in the
entity. Because of the factual nature of certain of the rules set forth therein,
neither Plans nor persons investing plan assets should acquire or hold
Securities in reliance upon the availability of any exception under the DOL
Regulations.
 
     In addition, the DOL Regulations provide that the term "equity interest"
means any interest in an entity other than an instrument which is treated as
indebtedness under applicable local law and which has no "substantial equity
features." If Notes of a particular Series are deemed to be indebtedness under
applicable
 
                                      117
<PAGE>
local law without any substantial equity features, an investing Plan's assets
would include such Notes, but would not, by reason of such purchase, include the
underlying assets of the related Trust Fund. However, without regard to whether
such Notes are treated as an equity interest for such purposes, the purchase or
holding of Notes by or on behalf of a Plan could be considered to result in a
prohibited transaction if the Issuer, the holder of an Equity Certificate or any
of their respective affiliates is or becomes a Party in Interest with respect to
such Plan, or if the Depositor, the Master Servicer, the Indenture Trustee or
the Owner Trustee has investment authority with respect to the assets of such
Plan.
 
     Any person who has discretionary authority or control respecting the
management or disposition of plan assets, and any person who provides investment
advice with respect to such assets for a fee, is a fiduciary of the investing
Plan. If the Residential Loans, Agency Securities, Mortgage Securities and other
assets included in a Trust Fund constitute plan assets, then any party
exercising management or discretionary control regarding those assets, such as
the Master Servicer or any Sub-Servicer, may be deemed to be a Plan "fiduciary"
subject to the fiduciary requirements of ERISA and the prohibited transaction
provisions of ERISA and the Code with respect to the investing Plan. In
addition, if the assets included in a Trust Fund constitute plan assets, the
purchase or holding of Securities by a Plan, as well as the operation of the
related Trust Fund, may constitute or involve a prohibited transaction under
ERISA and the Code.
 
     Some of the transactions involving the Securities that might otherwise
constitute prohibited transactions under ERISA or the Code might qualify for
relief from the prohibited transaction rules under certain administrative
exemptions, which may be individual or class exemptions. The DOL issued an
individual exemption, Prohibited Transaction Exemption 90-36 (the "Exemption"),
on June 25, 1990 to PaineWebber Incorporated, which generally exempts from the
application of the prohibited transaction provisions of Section 406 of ERISA,
and the excise taxes and civil penalties imposed on such prohibited transactions
pursuant to Section 4975(a) and (b) of the Code and Section 502(i) of ERISA,
certain transactions, among others, relating to the servicing and operation of
mortgage pools and the purchase, sale and holding of pass-through certificates,
such as a senior class of Certificates, underwritten by an Underwriter (as
hereinafter defined), provided that certain conditions set forth in the
Exemption are satisfied. For purposes of this Section "ERISA Considerations,"
the term "Underwriter" shall include (a) PaineWebber Incorporated, (b) any
person directly or indirectly, through one or more intermediaries, controlling,
controlled by or under common control with PaineWebber Incorporated and (c) any
member of the underwriting syndicate or selling group of which a person
described in (a) or (b) is a manager or co-manager with respect to a class of
Certificates.
 
     The Exemption sets forth six general conditions which must be satisfied for
a transaction involving the purchase, sale and holding of Certificates to be
eligible for exemptive relief thereunder. First, the acquisition of Certificates
by a Plan must be on terms that are at least as favorable to the Plan as they
would be in an arm's-length transaction with an unrelated party. Second, the
Exemption only applies to Certificates evidencing rights and interests not
subordinated to the rights and interests evidenced by the other Certificates of
the same Series. Third, the Certificates at the time of acquisition by the Plan
must be rated in one of the three highest generic rating categories by Standard
& Poor's Ratings Services, Moody's Investors Service, Inc., Duff & Phelps Credit
Rating Co. or Fitch Investors Service, L.P. (collectively, the "Exemption Rating
Agencies"). Fourth, the Trustee cannot be an affiliate of any other member of
the "Restricted Group" which consists of any Underwriter, the Depositor, the
Trustee, the Master Servicer, any Sub-Servicer, the obligor on credit support
and any obligor with respect to Trust Fund Assets constituting more than 5% of
the aggregate unamortized principal balance of the Trust Fund Assets in the
related Trust Fund as of the date of initial issuance of the Certificates.
Fifth, the sum of all payments made to and retained by the Underwriter(s) must
represent not more than reasonable compensation for underwriting the
Certificates; the sum of all payments made to and retained by the Depositor
pursuant to the assignment of the Trust Fund Assets to the related Trust Fund
must represent not more than the fair market value of such obligations; and the
sum of all payments made to and retained by the Master Servicer and any Sub-
Servicer must represent not more than reasonable compensation for such person's
services under the related Pooling and Servicing Agreement and reimbursement of
such person's reasonable expenses in connection therewith. Sixth, the investing
Plan must be an accredited investor as defined in Rule 501(a)(1) of Regulation D
of the Securities and Exchange Commission under the Securities Act of 1933, as
amended.
 
     The Exemption also requires that the Trust Fund meet the following
requirements: (i) the Trust Fund must consist solely of assets of the type that
have been included in other investment pools; (ii) certificates evidencing
interests in such other investment pools must have been rated in one of the
three highest categories of one of the
 
                                      118
<PAGE>
Exemption Rating Agencies for at least one year prior to the acquisition of
Certificates by or on behalf of a Plan or with plan assets; 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
acquisition of Certificates by or on behalf of a Plan or with plan assets.
 
     A fiduciary of a Plan contemplating purchasing a Certificate must make its
own determination that the general conditions set forth above will be satisfied
with respect to such Certificate. However, to the extent that Certificates are
subordinate, the Exemption will not apply to an investment by a Plan. In
addition, the Exemption will not apply to an investment by a Plan during a
Funding Period unless certain additional conditions specified in the related
Prospectus Supplement are satisfied. Furthermore, any Certificates representing
a beneficial ownership in unsecured obligations will not satisfy the general
conditions of the Exemption.
 
     If the general conditions of the Exemption are satisfied, the Exemption may
provide an exemption from the restrictions imposed by Sections 406(a) and 407(a)
of ERISA (as well as the excise taxes imposed by Sections 4975(a) and (b) of the
Code by reason of Section 4975(c) of the Code) in connection with the direct or
indirect sale, exchange, transfer, holding or the direct or indirect acquisition
or disposition in the secondary market of Certificates by Plans. However, no
exemption is provided from the restrictions of Sections 406(a)(1)(E), 406(a)(2)
and 407 of ERISA for the acquisition or holding of a Certificate on behalf of an
"Excluded Plan" by any person who has discretionary authority or renders
investment advice with respect to the assets of such Excluded Plan. For purposes
of the Certificates, an Excluded Plan is a Plan sponsored by any member of the
Restricted Group.
 
     If certain specific conditions of the Exemption are also satisfied, the
Exemption may provide an exemption from the restrictions imposed by Sections
406(b)(1) and (b)(2) of ERISA and the taxes imposed by
Section 4975(c)(1)(E) of the Code in connection with (1) the direct or indirect
sale, exchange or transfer of Certificates in the initial issuance of
Certificates between the Depositor or an Underwriter and a Plan when the person
who has discretionary authority or renders investment advice with respect to the
investment of Plan assets in the Certificates is (a) an obligor with respect to
5% or less of the fair market value of the Trust Fund Assets or (b) an affiliate
of such a person, (2) the direct or indirect acquisition or disposition in the
secondary market of Certificates by a Plan and (3) the holding of Certificates
by a Plan.
 
     Further, if certain specific conditions of the Exemption are satisfied, the
Exemption may provide an exemption from the restrictions imposed by Sections
406(a), 406(b) and 407(a) of ERISA, and the taxes imposed by Sections 4975(a)
and (b) of the Code by reason of Section 4975(c) of the Code for transactions in
connection with the servicing, management and operation of the related Trust
Fund. The Depositor expects that the specific conditions of the Exemption
required for this purpose will be satisfied with respect to the Certificates so
that the Exemption would provide an exemption from the restrictions imposed by
Sections 406(a) and (b) of ERISA (as well as the excise taxes imposed by
Sections 4975(a) and (b) of the Code by reason of Section 4975(c) of the Code)
for transactions in connection with the servicing, management and operation of
the related Trust Fund, provided that the general conditions of the Exemption
are satisfied.
 
     The Exemption also may provide an exemption from the restrictions imposed
by Sections 406(a) and 407(a) of ERISA, and the taxes imposed by Sections
4975(a) and (b) of the Code by reason of Section 4975(c) of the Code if such
restrictions are deemed to otherwise apply merely because a person is deemed to
be a Party in Interest with respect to an investing Plan by virtue of providing
services to the Plan (or by virtue of having certain specified relationships to
such a person) solely as a result of the Plan's ownership of Certificates.
 
     Before purchasing a Certificate, a fiduciary of a Plan should itself
confirm (a) that the Certificates constitute "certificates" for purposes of the
Exemption and (b) that the specific and general conditions and other applicable
requirements set forth in the Exemption would be satisfied. In addition to
making its own determination as to the availability of the exemptive relief
provided in the Exemption, the Plan fiduciary should consider its general
fiduciary obligations under ERISA in determining whether to purchase any
Certificates on behalf of a Plan.
 
     In addition to the Exemption, a Plan fiduciary or other investor using plan
assets should consider the availability of certain class exemptions granted by
the DOL ("Class Exemptions"), which may provide relief from certain of the
prohibited transaction provisions of ERISA and the related excise tax provisions
of the Code, including Prohibited Transaction Class Exemption ("PTCE") 83-1,
regarding transactions involving mortgage pool investment trusts; PTCE 84-14,
regarding transactions effected by a "qualified professional asset manager";
PTCE 90-1, regarding transactions by insurance company pooled separate accounts;
PTCE 91-38,
 
                                      119
<PAGE>
regarding investments by bank collective investment funds; PTCE 95-60, regarding
transactions by insurance company general accounts; and PTCE 96-23, regarding
transactions effected by an "in-house asset manager."
 
     In addition to any exemption that may be available under PTCE 95-60 for the
purchase, sale and holding of the Securities by an insurance company general
account, the Small Business Job Protection Act of 1996 added a new Section
401(c) to ERISA, which provides certain exemptive relief from the provisions of
Part 4 of Title I of ERISA, including the prohibited transaction provisions
thereof, and Section 4975 of the Code for transactions involving an insurance
company general account. Pursuant to Section 401(c) of ERISA, the DOL is
required to issue final regulations ("401(c) Regulations") no later than
December 31, 1997 which are to provide guidance for the purpose of determining,
in cases where insurance policies supported by an insurer's general account are
issued to or for the benefit of a Plan on or before December 31, 1998, which
general account assets constitute plan assets. Section 401(c) of ERISA generally
provides that, until the date which is 18 months after the 401(c) Regulations
become final, no person shall be subject to liability under Part 4 of Title I of
ERISA and Section 4975 of the Code on the basis of a claim that the assets of an
insurance company general account constitute plan assets, unless (i) as
otherwise provided by the Secretary of Labor in the 401(c) Regulations to
prevent avoidance of the regulations or (ii) an action is brought by the
Secretary of Labor for certain breaches of fiduciary duty which would also
constitute a violation of federal or state criminal law. Any assets of an
insurance company general account which support insurance policies issued to a
Plan after December 31, 1998 or issued to Plans on or before December 31, 1998
for which the insurance company does not comply with the 401(c) Regulations may
be treated as plan assets. In addition, because Section 401(c) does not relate
to insurance company separate accounts, separate account assets are still
treated as plan assets of any Plan invested in such separate account. Insurance
companies contemplating the investment of general account assets in the
Securities should consult with their legal counsel with respect to the
applicability of Section 401(c) of ERISA, including the general account's
ability to continue to hold the Securities after the date which is 18 months
after the date the 401(c) Regulations become final. The DOL proposed such
regulations on December 22, 1997, but they have not yet been finalized.
 
     Any plan fiduciary which proposes to cause a Plan to purchase Securities
should consult with its counsel with respect to the potential applicability of
ERISA and Section 4975 of the Code to such investment and the availability of
the Exemption or any Class Exemption in connection therewith. There can be no
assurance that the Exemption or any other individual or Class Exemption will
apply with respect to any particular Plan that acquires or holds Securities or,
even if all of the conditions specified therein were satisfied, that such
exemption would apply to all transactions involving the Trust Fund. The
Prospectus Supplement with respect to a Series of Securities may contain
additional information regarding the application of the Exemption or any other
exemption with respect to the Securities offered thereby.
 
                                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, as amended ("SMMEA"). Any class of Securities offered hereby and by
the related Prospectus Supplement that is not initially rated in one of the two
highest rating categories by at least one Rating Agency or that represents an
interest in a Trust Fund that includes junior Residential Loans will not
constitute "mortgage related securities" for purposes of SMMEA. The appropriate
characterization of those Securities not qualifying as "mortgage related
securities" ("Non-SMMEA Securities") under various legal investment
restrictions, and thus the ability of investors subject to these restrictions to
purchase such Securities, may be subject to significant interpretive
uncertainties. Accordingly, investors whose investment authority is subject to
legal restrictions should consult their own legal advisors to determine whether
and to what extent the Non-SMMEA Securities constitute legal investments for
them.
 
     Classes of Securities qualifying as "mortgage related securities" will
constitute legal investments for persons, trusts, corporations, partnerships,
associations, business trusts and business entities (including, but not limited
to, state-chartered savings banks, commercial banks, savings and loan
associations and insurance companies, as well as trustees and state government
employee retirement systems) created pursuant to or existing under the laws of
the United States or of any state (including the District of Columbia and Puerto
Rico) whose authorized investments are subject to state regulation to the same
extent that, under applicable law, obligations
 
                                      120
<PAGE>
issued by or guaranteed as to principal and interest by the United States or any
agency or instrumentality thereof constitute legal investments for such
entities. Pursuant to SMMEA, a number of states enacted legislation, on or
before the October 3, 1991 cutoff for such enactments, limiting to varying
extents the ability of certain entities (in particular, insurance companies) to
invest in "mortgage related securities" secured by liens on residential, or
mixed residential and commercial properties, in most cases by requiring the
affected investors to rely solely upon existing state law, and not SMMEA.
Accordingly, the investors affected by such legislation will be authorized to
invest in Securities qualifying as "mortgage related securities" only to the
extent provided in 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 "mortgage related
securities" without limitation as to the percentage of their assets represented
thereby, federal credit unions may invest in such securities, and national banks
may purchase such securities for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
Section 24 (Seventh), subject in each case to such regulations as the applicable
federal regulatory authority may prescribe. In this connection, the Office of
the Comptroller of the Currency (the "OCC") amended 12 C.F.R. Part 1 to
authorize national banks to purchase and sell for their own account, without
limitation as to a percentage of the bank's capital and surplus (but subject to
compliance with certain general standards in 12 C.F.R. Section 1.5 concerning
"safety and soundness" and retention of credit information), certain "Type IV
securities," defined in 12 C.F.R. Section 1.2(l) to include certain "residential
mortgage-related securities." As so defined, "residential mortgage-related
security" means, in relevant part, "mortgage related security" within the
meaning of SMMEA. The National Credit Union Administration ("NCUA") has adopted
rules, codified at 12 C.F.R. Part 703, which permit federal credit unions to
invest in "mortgage related securities" under certain limited circumstances,
other than stripped mortgage related securities and residual interests in
mortgage related securities, unless the credit union has obtained written
approval from the NCUA to participate in the "investment pilot program"
described in 12 C.F.R. Section 703.140.
 
     All depository institutions considering an investment in the Securities
should review the "Supervisory Policy Statement on Investment Securities and
End-User Derivatives Activities" (the "1998 Policy Statement") of the Federal
Financial Institutions Examination Council which has been adopted by the Board
of Governors of the Federal Reserve System, the Federal Deposit Insurance
Corporation, the OCC and the Office of Thrift Supervision effective May 26,
1998, and by the NUCA, effective October 1, 1998. The 1998 Policy statement sets
forth general guidelines which depository institutions must follow in managing
risks (including market, credit, liquidity, operational (transaction), and legal
risks) applicable to all securities (including mortgage pass-through securities
and mortgage-derivative products) used for investment purposes. The Office of
Thrift Supervision (the "OTS") has issued Thrift Bulletin 13a (December 1,
1998), "Management of Interest Rate Risk, Investment Securities and Derivatives
Activities," which thrift institutions subject to the jurisdiction of the OTS
should consider before investing in the Notes.
 
     Institutions whose investment activities are subject to regulation by
federal or state authorities should review rules, policies and guidelines
adopted from time to time by such authorities before purchasing any Securities,
as certain Series or classes may be deemed unsuitable investments, or may
otherwise be restricted, under such rules, policies or guidelines (in certain
instances irrespective of SMMEA).
 
     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, provisions which
may restrict or prohibit investment in securities which are not "interest
bearing" or "income paying," and, with regard to any Securities issued in
book-entry form, provisions which may restrict or prohibit investments in
securities which are issued in book-entry form.
 
     Except as to the status of certain classes of Securities as "mortgage
related securities," no representation is made as to the proper characterization
of the Securities for legal investment purposes, financial institution
regulatory purposes, or other purposes, or as to the ability of particular
investors to purchase Securities under applicable legal investment restrictions.
The uncertainties described above (and any unfavorable future determinations
concerning legal investment or financial institution regulatory characteristics
of the Securities) may adversely affect the liquidity of the Securities.
 
                                      121
<PAGE>
     Accordingly, all investors whose investment activities are subject to legal
investment laws and regulations, regulatory capital requirements or review by
regulatory authorities should consult their own legal advisors in determining
whether and to what extent the Securities constitute legal investments or are
subject to investment, capital or other restrictions and, if applicable, whether
SMMEA has been overridden in any jurisdiction relevant to such investor.
 
                             PLANS OF DISTRIBUTION
 
     The Securities offered hereby and by the Supplements to this Prospectus
will be offered in Series. The distribution of the Securities may be effected
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices to be
determined at the time of sale or at the time of commitment therefor. If so
specified in the related Prospectus Supplement, the Securities will be
distributed in a firm commitment underwriting, subject to the terms and
conditions of the underwriting agreement, by PaineWebber Incorporated
("PaineWebber") acting as underwriter with other underwriters, if any, named
therein. In such event, the Prospectus Supplement may also specify that the
underwriters will not be obligated to pay for any Securities agreed to be
purchased by purchasers pursuant to purchase agreements acceptable to the
Depositor. In connection with the sale of the Securities, underwriters may
receive compensation from the Depositor or from purchasers of the Securities in
the form of discounts, concessions or commissions. The Prospectus Supplement
will describe any such compensation paid by the Depositor.
 
     Alternatively, the Prospectus Supplement may specify that the Securities
will be distributed by PaineWebber acting as agent or in some cases as principal
with respect to Securities which it has previously purchased or agreed to
purchase. If PaineWebber acts as agent in the sale of Securities, PaineWebber
will receive a selling commission with respect to each Series of Securities,
depending on market conditions, expressed as a percentage of the aggregate
principal balance of the related Residential Loans as of the Cut-off Date. The
exact percentage for each Series of Securities will be disclosed in the related
Prospectus Supplement. To the extent that PaineWebber elects to purchase
Securities as principal, PaineWebber may realize losses or profits based upon
the difference between its purchase price and the sales price. The Prospectus
Supplement with respect to any Series offered other than through underwriters
will contain information regarding the nature of such offering and any
agreements to be entered into between the Depositor and purchasers of Securities
of such Series.
 
     The Depositor will indemnify PaineWebber and any underwriters against
certain civil liabilities, including liabilities under the Securities Act of
1933, or will contribute to payments PaineWebber and any underwriters may be
required to make in respect thereof.
 
     In the ordinary course of business, PaineWebber and the Depositor, or their
affiliates, may engage in various securities and financing transactions,
including repurchase agreements to provide interim financing of the Depositor's
residential loans pending the sale of such residential loans or interests
therein, including the Securities.
 
     The Depositor anticipates that the Securities will be sold primarily to
institutional investors. Purchasers of Securities, including dealers, may,
depending on the facts and circumstances of such purchases, be deemed to be
"underwriters" within the meaning of the Securities Act of 1933 in connection
with reoffers and sales by them of Securities. Securityholders should consult
with their legal advisors in this regard prior to any such reoffer or sale.
 
     As to each Series of Securities, only those classes rated in one of the
four highest rating categories by any Rating Agency will be offered hereby. Any
unrated class may be initially retained by the Depositor, and may be sold by the
Depositor at any time to one or more institutional investors.
 
                                      122
<PAGE>
                                 LEGAL MATTERS
 
     Certain legal matters in connection with the Securities will be passed upon
for the Depositor by Cadwalader, Wickersham & Taft, New York, New York.
 
                             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
 
     Unless otherwise specified in the related Prospectus Supplement, 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 Residential 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. 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 Residential Loans. No assurance can be given that values of any Residential
Properties have remained or will remain at their levels on the respective dates
of origination of the related Residential Loans. If the residential real estate
markets should experience an overall decline in property values such that the
outstanding principal balances of the Residential Loans in a particular Trust
Fund and any secondary financing on the related Residential Properties become
equal to or greater than the value of the Residential 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 Residential 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 Security of the related Series.
