Class A-1 (the "Class A-1 Certificates"), the Interest Only Class A-2 (the

in a trust fund (the "Trust Fund") established by the Depositor. (The Class A-1
Certificates evidence ownership of ___% of each principal payment on the
Mortgage Loans and ___% of each interest payment on the Mortgage Loans
((representing interest at a rate of ___% per annum on the unpaid principal
amount of the Class A-1 Certificates)). The Class A-2 Certificates evidence
ownership of ___% of each interest payment on the Mortgage Loans. The Class B
Certificates evidence ownership of ___% of each principal payment on the

Certificateholders to receive distributions with respect to the Mortgage Loans
will be subordinated to the rights of the Class A-1 and Class A-2

conveyed by the Depositor to the Trustee of the Trust Fund, pursuant to a

         estimated to be $______, will be approximately $______.

(4)      The Final Scheduled Distribution Date for each Class of Certificates
         is the date on which the Certificate Principal Amount or Notional
         Amount of all Certificates of such Class will have been reduced to
         zero, under the assumptions described herein.

         The Class and Class Certificates (the "Offered Certificates") are
offered by the Underwriter when, as and if delivered to and accepted by the
Underwriter and subject to its right to reject any order in whole or in part.
It is expected that the Offered Certificates will be available for delivery
(through the facilities of The Depository Trust Company) (, in definitive fully
registered form, at the offices of Credit Suisse First Boston Corporation) on
or about _______ __ , 199__.

         (The Offered Certificates are being offered by the Underwriter from
time to time in negotiated transactions or otherwise at prices to be determined
at the time of sale. Proceeds to the Depositor from the sale of the Offered
Certificates will be approximately $______, plus accrued interest thereon from
________, 199__, before deducting issuance expenses payable by the Depositor,
estimated to be approximately $__________. For further information with respect
to the plan of distribution and any discounts, commissions and profits on
resale that may be deemed to be underwriting discounts or commissions, see
"PLAN OF DISTRIBUTION" herein.)

         (The Offered Certificates will be issued only in book-entry form (the
"Book-Entry Certificates") and purchasers thereof will not be entitled to
receive definitive certificates except in the limited circumstances set forth
herein. The Book-Entry Certificates will be registered in the name of Cede &
Co., as nominee of The Depository Trust Company, which will be the "holder" or
"Certificateholder" of such Certificates, as such terms are used herein. See
"DESCRIPTION OF THE CERTIFICATES" herein.)

(continued from cover)

         The Mortgage Pool will consist primarily of one or more adjustable and
fixed rate, amortizing and balloon payment, recourse or non-recourse, newly
originated or seasoned (conventional) mortgage loans secured by first liens on
(commercial real estate properties), multifamily residential (rental)
properties, (cooperatively owned multifamily properties), and mixed
residential/commercial properties.) The Mortgage Pool will also include
(participation interests in such types of mortgage loans,) (installment
contracts for the sale of, and) mortgage loans secured by junior liens on, such
types of properties (and mortgage pass-through certificates) (such mortgage
loans (and other assets) the "Mortgage Loans"). (The Trust Fund will also
consist of (the reserve fund) (insurance policies on the mortgage loans) (a
letter of credit) (certificate guarantee insurance) (other enhancement device)
as set forth in "THE TRUST FUND.") The Certificate Principal Amount or Notional
Amount of each Class of Certificates is set forth above and is subject to an
aggregate permitted variance of plus or minus

         _____%. Distributions on the Certificates will be made (monthly) on
each Distribution Date (as defined herein) beginning in 199_. (The Class
Certificates do not represent a beneficial ownership interest in any Mortgage
Loans other than certain multifamily Mortgage Loans included in the Trust
Fund.)

         The Mortgage Loans may be prepaid at any time without penalty. (A
(lower) (higher) rate of principal prepayments than anticipated would
negatively affect the total return to investors in (Class A-1) (and) (Class B)
Certificates, which are being offered at a (discount) (premium) to their
principal amount.) Yields on the Class A-2 Certificates will be extremely
sensitive to the prepayment experience on the Mortgage Loans, and prospective
investors in such Certificates, which are entitled to payments of interest
only, should fully consider the associated risks, including the risk that such
investors, in circumstances of a higher than anticipated rate of principal
prepayment, could fail to fully recoup their initial investment. The yield to
investors in the Class Certificates, which are entitled to payments of
principal only, and only with respect to certain Mortgage Loans, could be
adversely affected by a low rate of principal prepayments on such Mortgage
Loans.

         No representation is made as to the anticipated rate of prepayments on
the Mortgage Loans or as to the anticipated yield to maturity of the
Certificates. See "THE TRUST FUND--The Mortgage Collateral" and "YIELD,
PREPAYMENT AND MATURITY CONSIDERATIONS" herein.

         (An election will be made to treat a segregated asset pool (the "REMIC
Pool") within the Trust Fund as a REMIC for federal income tax purposes. The
Regular Certificates will be Regular Interests in the REMIC Pool and the Class
R Certificates will be the sole class of Residual Interest in the REMIC Pool.
See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES" herein and in the Prospectus.)

         There is currently no secondary market for the Offered Certificates.
Credit Suisse First Boston Corporation (the "Underwriter") expects to make a
secondary market in the Offered Certificates, but has no obligation to do so.



                                      S-2
<PAGE>



There can be no assurance that a secondary market in the Offered Certificates
will develop or, if it does develop, that it will continue.

         The Certificates constitute a separate Series of Certificates being
offered by the Depositor from time to time pursuant to its Prospectus dated,
199_ which accompanies this Prospectus Supplement and of which this Prospectus
Supplement forms a part. This Prospectus Supplement does not contain complete
information about the Certificates offered hereby. Additional information is
contained in full in the Prospectus. Sales of the Certificates may not be
consummated unless the purchaser has received both this Prospectus Supplement
and the Prospectus.

         (IN CONNECTION WITH THIS OFFERING, THE UNDERWRITER MAY OVER-ALLOT OR
EFFECT TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICES OF THE
OFFERED CERTIFICATES AT LEVELS ABOVE THOSE THAT MIGHT OTHERWISE PREVAIL IN THE
OPEN MARKET. SUCH STABILIZING, IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME.)

         Until _____, 199_, all dealers effecting transactions in the Offered
Certificates, whether or not participating in this distribution, may be
required to deliver a Prospectus Supplement and Prospectus. This is in addition
to the obligation of dealers to deliver a Prospectus Supplement and Prospectus
when acting as Underwriters and with respect to their unsold allotments or
subscriptions.

                             AVAILABLE INFORMATION

         The Depositor has filed with the Securities and Exchange Commission
(the "Commission") a Registration Statement under the Securities Act of 1933,

Illinois 60661. Copies of such materials can be obtained at prescribed rates
from the Public Reference Section of the Commission at 450 Fifth Street, N.W.,

         The Trustee will mail monthly reports concerning the Certificates to
all registered Certificateholders.

                                            extent that the Available Distribution Amounts (as defined herein)
                                            are sufficient therefor, in an amount equal to the interest
                                            accrued during the related Interest Accrual Period (as defined
                                            below) on the Certificate Principal Amount of such Class at the
                                            applicable Pass-Through Rate (as defined herein) therefor, reduced
                                            by any Deferred Interest (as defined herein) allocable thereto as
                                            described herein. Any Deferred Interest with respect to the
                                            Mortgage Loans included in any Mortgage Loan Group will be
                                            allocated to the related Classes of Regular Certificates and the
                                            Class R Certificates in the manner described herein. The amount of
                                            any Deferred Interest allocated to a Class of Regular Certificates
                                            will be added to the Certificate Principal Amount thereof.
                                            Interest which accrues on each Class of the Regular Certificates
                                            will be calculated on the assumption that distributions in
                                            reduction of the Certificate Principal Amount thereof on a
                                            Distribution Date, and any additions to such Certificate Principal
                                            Amount in respect of Deferred Interest on such Distribution Date,
                                            are made at the end of the related Interest Accrual Period.

INTEREST ACCRUAL PERIOD...................  For the Fixed Rate Certificates (and the Class ( ) Certificates), the 
                                            calendar month preceding each Distribution Date. For the (Class ( ) 
                                            Certificates) (Floating Certificates), the one-month period
                                            ending on and including the day before each Distribution Date (or,

                                            including ___________, 19__ and ending on and including the day
                                            preceding such Distribution Date). Interest will be calculated on
                                            the basis of a 360-day year consisting of twelve 30-day months.

                                            discussion of the effect on the yield to Certificateholders
                                            arising from the lag between the accrual of interest on the
                                            Certificates and the distribution thereof.

                                            irrevocable letter of credit in an amount satisfactory to the
                                            Rating Agencies rating the Certificates to cover, among other
                                            things, shortfalls in collections on the Mortgage Loans due to
                                            losses and delinquencies thereon (and Basis Risk Shortfalls (as
                                            defined herein)), including shortfalls in interest received on

                                            of the Mortgage Loans as of the Cut-Off-Date. (The Depositor will
                                            have the right on any Distribution Date to cause the Trustee to
                                            pay over to the Depositor, free from the lien thereon, the amount
                                            by which the balance in the Reserve Fund exceeds the amount
                                            required to be maintained therein.)

SERVICING................................   (Various Servicers approved by the Master Servicer will provide customary

                                            thereon over their issue prices (including accrued interest, if
                                            any, payable on the Closing Date).) The prepayment assumption that
                                            is to be used in determining the rate of accrual of original issue

                                            amortization schedule and (ii) years past its stated maturity
                                            date, as described herein under "YIELD, PREPAYMENT AND MATURITY
                                            CONSIDERATIONS -- Weighted Average Life of the Regular
                                            Certificates")). No representation is made that the Mortgage Loans
                                            will prepay at such rate(s) or at any other rate or that the
                                            maturity dates for the Balloon Mortgage Loans will be extended in
                                            such manner or in any other manner.

                                            Holders will be required to allocate their basis in the Regular
                                            Certificates between their beneficial interests in the related
                                            Regular Interests and in their right to payments in respect of
                                            Basis Risk as described herein. Any amounts paid or accrued with
                                            respect to amounts due under the yield supplement agreements in
                                            excess of payments representing a return of basis if any,
                                            allocable thereto will be treated as ordinary income. The method
                                            of recovery of the portion, if any, of a Holder's basis in a
                                            Regular Certificate allocable to its interest in the respective
                                            yield supplement agreement is uncertain. The Depositor believes
                                            that the likelihood of any payments under the yield supplement
                                            agreements is remote and, therefore, a Holder's basis allocable
                                            thereto as of the Closing Date would be negligible.

                                            (A holder of a Class R Certificate will be required to include the
                                            taxable income or loss of the REMIC in determining its federal
                                            taxable income. It is anticipated that all or a substantial
                                            portion of the taxable income of the REMIC includible by a Class R
                                            Certificateholder will be treated as "excess inclusion" income
                                            subject to special limitations for federal income tax purposes.
                                            Further, significant restrictions apply to the transfer of a Class
                                            R Certificate. The Class R Certificates are "noneconomic residual
                                            interests," certain transfers of which may be disregarded for
                                            federal income tax purposes.)

                                  RISK FACTORS

         Prospective Certificateholders should consider, among other things,
the following factors in connection with a purchase of the Regular
Certificates.

         1. Delinquent Mortgage Loans; Matured Performing Mortgage Loans (;
Modified Mortgage Loan). Included in the Mortgage Pool are Mortgage Loans that,
as of the Cut-Off-Date, had up to Monthly Payments past due (and Mortgage Loans
that, as of the Cut-Off-Date, were delinquent as to their Balloon Payments but
as to which the related Borrowers continue to make Monthly Payments). The
Mortgage Pool includes Mortgage Loans that have had one or more delinquencies
during the 12 month period immediately preceding the Cut-Off-Date. (One or more
of the Mortgage Loans included in the Mortgage Pool have been modified by or on
behalf of the Depositor or the Unaffiliated Seller prior to such inclusion in
the Mortgage Pool.)

         As of the Cut-Off-Date, no Mortgage Loan has or more Monthly Payments
past due. As of the Closing Date, all Monthly Payments due on any Mortgage Loan
on ____ or before ________, 199__ will have been made. (Mortgage Loans having
an aggregate Scheduled Principal Balance of approximately $_______,
representing % of the aggregate Scheduled Principal Balance of the Mortgage
Loans as of the Cut-Off-Date, will have a Monthly Payment which is more than 60
days past due at the Closing Date if no Monthly Payments are received on such
Mortgage Loans from the Cut-Off-Date to the Closing Date and in such event will
be Specially Serviced Mortgage Loans as of the Closing Date.)

         (Mortgage Loans having an aggregate Scheduled Principal Balance of
approximately $__________, representing ___% of the aggregate Scheduled
Principal Balance of the Mortgage Loans as of the Cut-Off-Date, are Mortgage
Loans that are delinquent as to their Balloon Payments as of the Cut-Off-Date,
that have not yet been the subject of modification as a consequence thereof and
on which the Borrowers continue to make Monthly Payments in accordance with
their original terms ("Matured Performing Mortgage Loans"). Matured Performing
Mortgage Loans that do not contain principal amortization schedules are
expected to be modified to provide for extended maturity dates. See "THE TRUST
FUND -- The Mortgage Collateral" herein and "THE MORTGAGE POOLS" in the
Prospectus.)

         Investors should consider the risk that the inclusion of delinquent
Mortgage Loans (and Matured Performing Mortgage Loans) in the Mortgage Pool may
affect the rate of defaults and prepayments on the Mortgage Loans and the yield
on the Offered Certificates. See "YIELD, PREPAYMENT AND MATURITY
CONSIDERATIONS" herein.

         2. Multifamily and Commercial Lending. Borrower Default; Balloon
Payments. Multifamily and commercial lending is generally viewed as exposing
the lender to a greater risk of loss than one-to four-family residential
lending. Multifamily and commercial lending typically involves larger loans to
a single obligor or groups of related obligors than residential one-to
four-family mortgage loans. (The Mortgage Loans are not insured or guaranteed
against default by any governmental entity or by any private mortgage insurer,)
(and there is no obligation on the part of any Person to repurchase or replace
any delinquent or defaulted Mortgage Loan, (except (the Unaffiliated Seller)
(the Master Servicer) under the circumstances set forth herein). See "THE TRUST
FUND -- Representations and Warranties" herein and "THE MORTGAGE POOLS --
Representations and Warranties" in the Prospectus.

         The repayment of loans secured by income-producing properties is
typically dependent upon the successful operation of the related real estate
project rather than upon the liquidation value of the underlying real estate.

         Information concerning the debt service coverage ratios of (certain
of) the Mortgage Loans is set forth in Exhibit Y to this Prospectus Supplement.
(As indicated therein, the net operating income from certain of the Mortgaged
Properties is currently insufficient to cover debt service payments on the
related Mortgage Loans, and in the case of certain other Mortgage Loans the
Depositor does not have current information concerning net operating income
from the related real estate projects.) Even where the net operating income
generated by a Mortgaged Property is currently sufficient to cover debt service
payments on the related Mortgage Loan, there can be no assurance that this will
continue to be the case in the future. In the case of an adjustable rate
Mortgage Loan, an increase in the Mortgage Interest Rate will increase the debt
service and could impair the Borrower's ability to repay the Mortgage Loan. Net
operating income from a real estate project 


                                     S-15
<PAGE>

may be reduced, and the Borrower's ability to repay the loan impaired, as a
result of an increase in vacancy rates for the project, a decline in rental
rates as leases are renewed or entered into with new tenants, an increase in
operating expenses of the project and/or an increase in capital expenditures
needed to maintain the project and make improvements required by tenants. In
the case of Mortgage Loans that are secured by owner-occupied Mortgaged
Properties or Mortgaged Properties leased to a single tenant, a decline in the
financial condition of the Borrower or single tenant, as applicable, may have a
disproportionately greater effect on the net operating income from such
Mortgaged Properties than would be the case with respect to Mortgage Properties
with multiple tenants. (A substantial portion) of the Mortgage Loans are
nonrecourse loans or loans for which recourse may be restricted or
unenforceable, as to which, in the event of Borrower default, recourse may be
had only against the specific real property and such other assets, if any, as
have been pledged to secure the Mortgage Loan. See "CERTAIN LEGAL ASPECTS OF
THE MORTGAGE LOANS --Anti-Deficiency Legislation" in the Prospectus. With
respect to those Mortgage Loans that provide for recourse against the Borrower
and its assets generally, there can be no assurance that such recourse will
ensure a recovery in respect of a defaulted Mortgage Loan greater than the
liquidation value of the related Mortgaged Property. The liquidation value of
any Mortgaged Property may be adversely affected by risks generally incident to
interests in real property, including changes or continued weakness in general
or local economic conditions and/or specific industry segments; declines in
real estate values; supply and demand in the market for the type of Mortgaged
Property securing the Mortgage Loan; declines in rental or occupancy rates;
increases in interest rates, real estate and personal property tax rates,
energy costs and other operating expenses; the availability of real estate
financing for the relevant type of Mortgaged Property; changes in governmental
rules, regulations and fiscal policies, including environmental legislation and
rent control laws; acts of God; and other factors which are beyond the Master
Servicer's or the Special Servicer's control. Although the Master Servicer or
the Special Servicer is obligated to cause standard hazard insurance to be
maintained with respect to each Mortgage Loan, insurance with respect to
extraordinary hazards such as earthquakes and floods is generally not required
to be maintained, and insurance is not available with respect to many of the
other risks listed above.

         Mortgage Loans representing approximately % of the aggregate Scheduled
Principal Balance of the Mortgage Loans as of the Cut-Off-Date are not fully
amortizing over their terms to maturity, and, thus, may have substantial
principal balances ("Balloon Payments") due at their stated maturity (such
Mortgage Loans are sometimes hereinafter referred to as "Balloon Mortgage
Loans"). In addition, certain Mortgage Loans provide for monthly (or other
periodic) payments of interest at a Payment Rate which could be less than the
Mortgage Interest Rate for such Mortgage Loan for some portion of the loan
term. "Payment Rate" means the per annum rate of interest that becomes due for
each such Mortgage Loan on each payment date. The terms of such a Mortgage Loan
provide that its principal balance is increased periodically by an amount
reflecting the difference between the Payment Rate and the Mortgage Interest
Rate, resulting in negative amortization. Accordingly, such Mortgage Loans
could also have Balloon Payments due at their stated maturity or increases in
expected Balloon Payments that might not arise in other interest rate
scenarios. In certain circumstances, the Agreement permits the modification of
Mortgage Loans to create or to increase existing Balloon Payments. Mortgage
Loans with Balloon Payments involve a greater degree of risk than fully
amortizing loans because the ability of a Borrower to make a Balloon Payment
typically will depend upon its ability either to refinance the loan or to sell
the related Mortgaged 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 attempted sale or refinancing, the
Borrower's equity in the related Mortgaged Property, the financial condition of
the Borrower and operating history of the related Mortgaged Property, tax laws,
prevailing economic conditions and the availability of credit for (commercial)
(multifamily residential) real estate projects generally.

         (In order to produce a greater recovery on a present value basis on
defaulted Mortgage Loans, the Special Servicer has considerable flexibility
under the Agreement to extend and modify Mortgage Loans which are in default or
as to which a payment default is reasonably foreseeable, including in
particular Balloon Payments. More specifically, subject to the overall goal of
producing a greater recovery on a present value basis for the defaulted
Mortgage Loans than would result from foreclosure and to certain conditions set
forth in the Agreement, the Special Servicer has the power, among other things,
to forgive permanently the payment of principal or interest or both, to lower
or modify the Mortgage Interest Rates or Payment Rates or to modify the
schedule for payments of principal and interest. Any extension of the scheduled
maturity date of the loan may cause the weighted average lives of the
Certificates to be longer than if the loan had paid under its original terms.)

         (The Special Servicer receives a Workout Fee (as defined herein) which
is based on receipts from or proceeds of such Mortgage Loans. While such
flexibility with respect to modifications and payment of compensation to the


                                     S-16
<PAGE>

Special Servicer in the form of a Workout Fee is designed to increase the
present value of receipts from or proceeds of Mortgage Loans which are in
default or as to which default is reasonably foreseeable, there can be no
assurance that it will do so. See "SERVICING OF THE MORTGAGE LOANS --
Modifications, Waivers and Amendments" and "--Servicing Compensation and
Payment of Expenses" herein and in the Prospectus.)

         (3. Absence of Servicer Advances and Limits of Reserve Fund. Neither
the Master Servicer nor the Special Servicer is obligated to make advances with
respect to payments of principal or interest due on delinquent or defaulted
Mortgage Loans (, with respect to Senior Lien Advances) or, as long as amounts
remain in the Reserve Fund, with respect to costs and expenses that may be
incurred in connection with the servicing of the Mortgage Loans. (Any
delinquent Monthly Payments (as defined herein) or Assumed Scheduled Payments
(i.e., payments assumed to be due following any delinquent Balloon Payment), as
well as actual or assumed write-offs in connection with restructured Mortgage
Loans, certain other distributions of principal and interest, certain costs or
expenses, including certain fees payable to the Special Servicer and Basis Risk
Shortfalls (including shortfalls in interest received on Mortgage Loans as a
result of prepayments) will be covered by draws on the Reserve Fund to the
extent sufficient funds are available therein. Consequently, the Reserve Fund
serves simultaneously as a source of liquidity and credit support for the
Regular Certificates, as a source of protection for such Regular Certificates
against shortfalls in interest on Mortgage Loans due to prepayments and as a
source of Basis Risk protection for the Regular Certificates.) (As more fully
described herein, when the amount on deposit in the Reserve Fund is less than
the Liquidity Amount (as defined herein), the Reserve Fund will only be
available to make certain minimum distributions on the Class ( ) Certificates;
(or, after the Class ( ) Certificates have been retired, on the Class ( )
Certificates).) See "DESCRIPTION OF THE CERTIFICATES -- Distributions --
Allocation Among Classes" herein.)

         4. Priority of Payments. (All amounts received on or in respect of the
Mortgage Loans in Mortgage Loan Group ((including related draws on the Reserve
Fund)) will be applied first to interest and principal then distributable with
respect to the Class Certificates, and only thereafter will be applied to
amounts then distributable with respect to the Class Certificates. Principal
distributable on the Class Certificates generally will include all principal
received, due (other than Balloon Payments) but not received, or deemed to be
due, on the Group Mortgage Loans. Furthermore, pursuant to the subordination of
the Class Certificates to the Class Certificates, remaining amounts received on
or with respect to Mortgage Loans in Mortgage Loan Group, otherwise allocable
to such subordinated class, will first be applied to cover any shortfalls in
minimum distribution to the Class Certificates to the extent amounts received
on or with respect to the Mortgage Loans in Mortgage Loan Group are not
sufficient therefor.)

         (In no event will amounts received on or with respect to the Mortgage
Loans in Mortgage Loan Group be available to make distributions to the Class
Certificates, and accordingly the Class Certificates could receive
distributions from such amounts at times when the Class Certificates are not
receiving minimum distributions in full. Even in the absence of shortfalls in
payments on the Group Mortgage Loans, if the rate of principal payments on the
Group Mortgage Loans, the Class Certificates could be entitled to distributions
of Optimal Mortgage Loan Principal (as defined herein) for Mortgage Loan Group
at times when the Class Certificates are still outstanding).

         Distributions of interest and principal with respect to the Class
Certificates will be subordinate to distributions of interest and principal
with respect to the Class Certificates to the extent that no distribution of
interest or principal is permitted to be made with respect to the Class
Certificates on any Distribution Date until interest and principal then payable
to the Class Certificates have been paid and, so long as any Class Certificates
remain outstanding, until the amount in the Reserve Fund is restored to at
least the Liquidity Amount. (Repeat for each additional subordinate Class.)

         To the extent interest distributable in respect of a Class of Regular
Certificates on any Distribution Date is not paid as a result of the foregoing
priorities or otherwise, the amount of such interest, together with interest
accrued thereon at the applicable Pass-Through Rate, compounded monthly, will
be added to amounts to be distributed on subsequent Distribution Dates.
Certificate Principal Amounts of Regular Certificates will be reduced only as a
result of distributions in respect thereof. See "DESCRIPTION OF THE
CERTIFICATES -- Distributions" herein.

         (5. Basis Risk and Prepayment Shortfalls. Under certain circumstances,
interest accrued on the Regular Certificates as of any Distribution Date could
exceed interest (net of applicable servicing fees) accrued on the Mortgage
Loans. Such a shortfall could arise due to, among other things, variations in
the difference between (LIBOR) and the 


                                     S-17
<PAGE>

Indexes for the Group and Group Mortgage Loans, variations in the difference
between (COFI) and the interest accrued on the Group Mortgage Loans, variations
in interest rate adjustment dates and interest rate maximums for such Mortgage
Loans relative to those for the Floating Rate Certificates, differences in the
number of days for interest accrual periods for payments on Mortgage Loans and
Interest Accrual Periods for corresponding Distribution Dates for the Regular
Certificates, the existence of Group (1F) Mortgage Loans with Net Mortgage
Interest Rates and Group (1A) Mortgage Loans with Floor Interest Rates, which
could result in Net Mortgage Interest Rates that are below the weighted average
of the Pass-Through Rates for the Fixed Rate Certificates, conversion of
certain adjustable rate Mortgage Loans to fixed rate Mortgage Loans, and net
shortfalls in interest collected on Principal Prepayments or Balloon Payments.
(The Reserve Fund will be available to cover shortfalls due to Basis Risk.) Any
such amounts will be applied, first, to such shortfalls incurred by the Class
Certificates (, second to such shortfalls incurred by the Class Certificates)
and last to such shortfalls incurred by the Class Certificates. See
"DESCRIPTION OF THE CERTIFICATES -- Distributions -- Basis Risk" herein.)

         6. Enforceability. (A substantial majority) of the Mortgages contain
due-on-sale clauses, which permit the lender to accelerate the maturity of the
Mortgage Loan if the Borrower sells, transfers or conveys the related Mortgaged
Property or its interest in the Mortgaged Property. Such clauses are generally
enforceable subject to certain exceptions.

         (Substantially all) of the Mortgages include debt-acceleration
clauses, which permit the lender to accelerate the debt upon a monetary or
nonmonetary default of the Borrower. The courts of all states will enforce
clauses providing for acceleration in the event of a material payment default
after the giving of appropriate notices. The equity courts of any state,
however, may refuse to permit the foreclosure of a mortgage or deed of trust
when an acceleration of the indebtedness would be inequitable or unjust or the
circumstances would render the acceleration unconscionable.

         (Included in the Mortgage Pool are Installment Contracts which are
generally enforceable subject to certain exceptions. See "CERTAIN LEGAL ASPECTS
OF THE MORTGAGE LOANS --Installment Contracts" in the Prospectus.) (Some) of
the Mortgage Loans may be secured by an assignment of leases and rents pursuant
to which the Borrower typically assigns its right, title and interest as
landlord under the leases on the related Mortgaged Property and the income
derived therefrom to the lender as further security for the related Mortgage
Loan, while retaining a license to collect rents for so long as there is no
default. In the event the Borrower defaults, the license terminates and the
lender is entitled to collect rents. Such assignments are typically not
perfected as security interest prior to actual possession of the cash by the
lender. Some state laws may require that the lender take possession of the
Mortgaged Property and obtain a judicial appointment of a receiver before
becoming entitled to collect the rents. In addition, if bankruptcy or similar
proceedings are commenced by or in respect of the Borrower, the lender's
ability to collect the rents may be adversely affected. See "CERTAIN LEGAL
ASPECTS OF THE MORTGAGE LOANS" in the Prospectus.

         7. Limited Obligations. The Certificates will represent beneficial
ownership interests solely in the assets of the Trust Fund and will not
represent an interest in or obligation of the Depositor or any other Person.
Distributions on any Class of Regular Certificates will depend solely on the
amount and timing of payments and other collections in respect of the Mortgage
Loans (and amounts on deposit in the Reserve Fund) (and collections in respect
of the other credit enhancement devices provided for herein). Although amounts,
if any, otherwise distributable to Holders of the Class Certificates will be
available to make distributions on the Class Certificates on any Distribution
Date to the extent set forth herein, (repeat for each additional subordinate
Class) there can be no assurance that these amounts, together with other
payments and collections in respect of the Mortgage Loans (and amounts
available to be withdrawn from the Reserve Fund) (and collections in respect of
the other credit enhancement devices provided for herein), will be sufficient
to make full and timely distributions on such Class Certificates.

         8. Limited Liquidity. The Underwriter has advised the Depositor that
it intends to make a secondary market (either directly and/or through one or
more affiliates) in the Offered Certificates, but has no obligation to do so.
There can be no assurance that a secondary market will develop for any Class of
Offered Certificates or, if it does develop, that it will provide the Holders
of such Certificates with liquidity of investment or that it will remain for
the term of such Certificates. No arrangement for listing of the Offered
Certificates on a securities exchange is being made.

         9. Variability in Average Life of Regular Certificates. The payment
experience on the Mortgage Loans will affect the actual payment experience on
and the weighted average lives of the Regular Certificates and accordingly may
affect the yield on the Regular Certificates. Since prepayments on the Mortgage
Loans (including prepayments 


                                     S-18
<PAGE>

resulting from modifications, defaults or liquidations or repurchases due to
certain breaches of representations and warranties) and other principal
payments (including Balloon Payments) on the Mortgage Loans are initially
directed to reduce the respective Certificate Principal Amounts of the Class
Certificates, principal payments on the Mortgage Loans will have a
disproportionately greater tendency to shorten the weighted average lives of
the Class Certificates relative to the Class Certificates and to shorten the
weighted average lives of the Class Certificates relative to the Class
Certificates, and so forth.

         In contrast, (a substantial portion of) the excess of interest due on
the Mortgage Loans, net of servicing compensation, over interest due on the
Regular Certificates will generally be applied to the Class Certificates as
described herein under "DESCRIPTION OF THE CERTIFICATES -- Distributions --
Allocation Among Classes. " Accordingly, while the amount of such excess
interest will generally be affected primarily by changes in interest rates and
the interest rate adjustment terms of the Mortgage Loans as described above
under "--Basis Risk and Prepayment Shortfalls," any payment experience which
would reduce such excess interest, including prepayments (Mortgage Loans having
higher interest rates being more likely to prepay), will have a tendency to
extend the weighted average lives of the Class Certificates. Likewise, any
payment experience which would increase such excess interest, including the
extension of due dates for certain Balloon Payments, will have a tendency to
shorten the weighted average lives of the Class Certificates and to extend the
weighted average lives of the Class Certificates. The level of such excess
interest will also be affected by other factors described above under "--Basis
Risk and Prepayment Shortfalls" and under "DESCRIPTION OF THE CERTIFICATES --
Distributions -- Basis Risk" herein.

         Prepayments on the Mortgage Loans will be influenced by the prepayment
provisions of the related Notes and may also be affected by a variety of
economic, geographic and other facts, including the difference between the
interest rates on the Mortgage Loans (giving consideration to the cost of
refinancing) and prevailing mortgage rates and the availability of refinancing.
In general, if prevailing interest rates fall significantly below the interest
rates on the Mortgage Loans, the rate of prepayment on the Mortgage Loans (and
particularly on Mortgage Loans with fixed Mortgage Interest Rates or with
minimum adjustable Mortgage Interest Rates that are higher than prevailing
interest rates) would be expected to increase. Conversely, if prevailing
interest rates are at a level below the Mortgage Interest Rates on the Mortgage
Loans and rise significantly above such Mortgage Interest Rates, the rate of
prepayment would be expected to decrease. (A significant number) of the
Mortgage Loans either did not provide for any lockout period in which
prepayments are prohibited or for any prepayment premium, penalty or charge in
connection with the prepayment thereof, or if such provisions were included in
the Notes they have expired. (Some) of the Mortgage Loans, however, continue to
have lockout periods or prepayment premiums or penalties which could be a
deterrent to prepayments. The Depositor makes no representation as to the
effect of such lockout periods, premiums or penalties on the rate of prepayment
of the related Mortgage Loans. Except in limited circumstances, the Depositor
has not verified the prepayment terms of the Notes relating to the Mortgage
Loans.

         Delays in liquidations of defaulted Mortgage Loans and modifications
extending the maturity of Mortgage Loans will tend to extend the payment of
principal of the Mortgage Loans. Because a significant number of Mortgage Loans
have Balloon Payments due at maturity and because the ability of the Borrower
to make a Balloon Payment typically will depend upon its ability either to
refinance the loan or to sell the related Mortgaged Property, there is a risk
that a number of Mortgage Loans having Balloon Payments may default at
maturity, or that the Special Servicer may extend the maturity of a number of
such Mortgage Loans in connection with workouts. In the case of defaults,
recovery of proceeds may be delayed by, among other things, bankruptcy of the
Borrower or adverse conditions in the market where the property is located. (In
order to minimize losses on defaulted Mortgage Loans, the Special Servicer is
given considerable flexibility under the Agreement to modify Mortgage Loans
that are in material default or as to which a payment default is reasonably
foreseeable or has occurred.) Certificateholders are not entitled to receive
distributions of Balloon Payments when due except to the extent they are
actually received and instead are entitled only to receive prepayments when
received and Assumed Scheduled Payments which would be due if no Balloon
Payments were required. With respect to delinquent or defaulted Mortgage Loans
(including REO Mortgage Loans), Certificateholders are entitled to receive only
scheduled Monthly Payments or Assumed Scheduled Payments until final
liquidation, except that an earlier partial payment of principal may be
required upon foreclosure, if the appraised value of the related Mortgaged
Property is less than the actual principal balance of the Mortgage Loan, or
upon a modification. See "SERVICING OF THE MORTGAGE LOANS - -- Modifications,
Waivers and Amendments" herein and in the Prospectus.

         Any changes in weighted average life may adversely affect the yield to
Certificateholders. Prepayments resulting in a shortening of weighted average
lives of any of the Regular Certificates may be made at a time of low interest
rates when a Holder may be unable to reinvest the resulting payments of
principal on its Certificates at a rate comparable to the Pass-Through Rate
payable on such Certificates, while delays and extensions resulting in a
lengthening of such weighted average lives may occur at a time of high interest
rates when a Holder may have been able to reinvest principal payments that
would otherwise have been received by it at higher rates. In contrast, because
the Class Certificates are being offered at a discount, and because the Class (
) Certificates are being offered at a premium, their effective yields will
depend to a significant extent on the rate at which any excess interest
materializes and is applied to make distributions of principal in respect of
such Classes of Certificates as described above. The yield on the Class
Certificates may be adversely affected to the extent their weighted average
lives are extended due to a reduction in such excess interest and the yield on
the Class Certificates may be adversely affected to the extent their weighted
average lives are shortened due to an increase in such excess interest. See
"YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS" and "THE TRUST FUND" herein.

         10. Environmental Law Considerations. At the time the Mortgage Loans
were originated it is possible that no environmental assessment or a very
limited environmental assessment of the Mortgaged Properties was conducted.

         (The Agreement provides that the Special Servicer shall, at the
expense of the Trust Fund, obtain an environmental assessment with respect to
any Mortgaged Property prior to acquiring title thereto or assuming its
operation. This requirement effectively precludes enforcement of the security
for the related Note until a satisfactory environmental assessment is obtained
or any required remedial action is taken, reducing the likelihood that the
Trust Fund will become liable for any Environmental Condition affecting a
Mortgaged Property, but making it more difficult to foreclose. However, there
can be no assurance that the requirements of the Agreement will in fact
insulate the Trust Fund from liability for Environmental Conditions.)

         Under the laws of certain states where the Mortgaged Properties are
located, failure to perform the remediation of Environmental Conditions
required or demanded by the state may give rise to a lien on a Mortgaged
Property to ensure the reimbursement of remediation costs incurred by the
state. Although the costs of remedial action could be substantial, the state of
the law in certain of these jurisdictions presently is unclear as to whether
and under what conditions such costs (or the requirements to otherwise
undertake remedial actions) would be imposed on a secured lender such as the
Trust Fund. However, under the laws of some states and under applicable federal
law, a lender may be liable for such costs in certain circumstances as the
"owner" or "operator" of the Mortgaged Property. (The Reserve Fund will be
available to cover shortfalls in amounts distributable to Certificateholders
occasioned by the imposition of clean-up costs on the Trust Fund. Shortfalls
occurring as the result of imposition of any such costs after the Reserve Fund
is depleted will be borne first by Holders of Class ( ) Certificates (, second
by Holders of Class ( ) Certificates) and finally by Holders of Class ( )
Certificates.) See "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS --
Environmental Risks" in the Prospectus.

         (11. Industry Concentration. Approximately Mortgage Loans, which
represent approximately % of the aggregate Scheduled Principal Balance of the
Mortgage Loans as of the Cut-Off-Date, are secured by Mortgaged Properties
dedicated to the industry. The industry may be adversely affected by a variety
of economic, demographic, social, tax, legal and other factors to a greater
degree than other industries. Because of the relative lack of industry
diversity in respect of the Mortgaged Properties securing the Mortgage Loans,
losses on the Mortgage Loans may be higher than would be the case if such
Mortgage Loans were more diversified.)

         (12. Limited Information; Inadequate or Obsolete Loan Documentation.
The information set forth in this Prospectus Supplement with respect to
Mortgage Loans is derived from books and records of the loan originators, from
limited discussions with personnel of the loan originators, as well as a
limited review of the credit and legal files relating to the Mortgage Loans.
Due to the fact that many of the loan originators are in conservatorship or
receivership and that the operations of some of the loan originators are in the
process of being wound down, there have been reductions in the staff of many of
the loan originators and not all the personnel of the loan originators who
might be knowledgeable about the Mortgage Loans are available to provide
information to the Depositor. Thus, it is possible that this Prospectus
Supplement does not contain information regarding the Mortgage Loans which
would have been disclosed if the structure and personnel of the loan
originators had not been affected by such institutions' having been 


                                     S-20
<PAGE>

placed in conservatorship or receivership. In addition, the status of the loan
originators may have contributed to the loan documentation being more incomplete
than might otherwise have been the case.)

         (13. Geographic Concentration. Approximately ( ) Mortgage Loans
representing approximately ( )% of the aggregate Scheduled Principal Balance of
the Mortgage Loans as of the Cut-Off-Date, are secured by Mortgaged Properties
located in the State of . (Improvements on Mortgaged Properties located in may
be more susceptible to certain types of special hazards not covered by
insurance (such as earthquakes) than properties located in other parts of the
country.) In addition the economy of the State of may be adversely affected to
a greater degree than that of other areas of the country by certain
developments affecting industries concentrated in such states. Moreover, in
recent periods, several regions of the United States (including ) have
experienced significant downturns in the market value of real estate. (Because
of the relative lack of geographic diversity in the Mortgage Loan Groups,
losses on the related Mortgage Loans may be higher than would be the case if
such Mortgage Loan Groups were more diversified.)

         (The Mortgage Pool includes Mortgaged Properties located in the
State(s) of (Florida) (and) (Louisiana) which may have been affected by
Hurricane Andrew. of the Mortgaged Properties are located in Dade County, the
county in Florida most affected by the hurricane. The Agreement will contain a
representation and warranty that, as of the Closing Date, each Mortgaged
Property is covered by a fire and extended perils insurance policy issued by a
"qualified insurer" (as defined in the Agreement) and is free of material
damage and in good repair or, if materially damaged, such Mortgaged Property is
also covered by a rent interruption insurance policy. See "THE MORTGAGE POOLS
- -- Representations and Warranties" in the Prospectus.)

         For additional information regarding the geographic diversity of the
Mortgage Pool, see Exhibit X to this Prospectus Supplement.

         (14. Mortgage Loan Concentration. Approximately Mortgage Loans with
Cut-Off-Date principal balances greater than comprise approximately % of the
aggregate Principal Balance of the Mortgage Loans. As a result of this relative
concentration of the Mortgage Loans, losses or prepayments on, or modifications
of (including an extension of the maturity date), any such Mortgage Loans are
likely to have a greater effect on the yield to Holders of the Bonds or the
anticipated weighted average lives of the Bonds than might otherwise be the
case had such concentration not existed.)

         (15. Mortgage Loans to One Borrower. Mortgage Loans with an aggregate
Scheduled Principal Balance of $ (comprising approximately % of the aggregate
Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off-Date) are
payable by one borrower.) (Such Mortgage Loans are Balloon Mortgage Loans
maturing in.) The inability of this borrower to repay the principal of such
Mortgage Loans on the stated maturity dates thereof ((due to an inability to
refinance the Mortgage Loans or to sell the related properties)) would be
likely to cause greater losses on the Offered Certificates than might be the
case if such Mortgage Loans were not payable by a single entity. Similarly, any
modification of such Mortgage Loans that extends the maturities thereof would
be likely to cause an extension of the weighted average lives of the Offered
Certificates beyond that which might otherwise be the case.

                        DESCRIPTION OF THE CERTIFICATES

         The Certificates are to be issued pursuant to the Agreement, dated as
of the Cut-Off-Date, among the Depositor, the Master Servicer, the Special
Servicer and the Trustee. Reference is made to the Prospectus for important
additional information regarding the terms and conditions of the Agreement and
the Certificates. The Trustee will provide Certificateholders without charge,
(and to non-Certificateholders for a reasonable charge,) on written or oral
request, a copy of the Agreement (, as well as the Collateral Security
Agreement (the "Collateral Security Agreement") pursuant to which the Reserve
Fund is held). Requests should be addressed to, Attention: or by calling
(___)___-____.

         The following summaries describing certain provisions of the
Certificates, the Agreement and the Collateral Security Agreement do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, the provisions of the Agreement and the Collateral Security
Agreement, as the case may be. Capitalized terms used herein and not otherwise
defined herein have the meanings assigned in the Agreement or the Collateral
Security Agreement, as the case may be.

                                    GENERAL

         The Certificates will consist of the Class ( ), Class ( ), Class ( )
and Class R Certificates. All Classes of Certificates other than the Class R
Certificates are collectively referred to herein as "Regular Certificates." The
Regular Certificates (other than the Class ( ) Certificates) are collectively
referred to herein as the "Offered Certificates." The Class ( ), Class ( ) and
Class ( ) Certificates are collectively referred to herein as "Fixed Rate
Certificates" and the Class ( ) Certificates are sometimes referred to herein
as "Floating Rate Certificates." The Certificates will represent beneficial
ownership interests in the Trust Fund consisting of, among other things, the
Mortgage Loans, together with payments thereon, and certain other assets,
including (the reserve fund established with respect to the Certificates,) (the
insurance policies,) (the credit enhancement devices set forth herein) (;
however, the Class ( ) Certificates do not represent a beneficial ownership
interest in any Mortgage Loans other than Eligible Multifamily Mortgage Loans).
The Class Certificates are "interest only" Certificates. The Class Certificates
are "principal only" Certificates and will not accrue any interest. For federal
income tax purposes, the Regular Certificates will be Regular Interests and
will be entitled to receive certain payments from the Reserve Fund (limited to
amounts therein) in respect of Basis Risk as described herein.

         The original Certificate Principal Amounts (, and in the case of
"interest only" Certificates, Notional Amounts,) of each class of the
Certificates are shown on the cover page of this Prospectus Supplement. The
Class Certificates will be issued only in fully registered form in minimum
denominations of $______ and integral multiples (thereof) (of $_______ in
excess thereof). (The Class Certificates will be issued in minimum
denominations of % and integral multiples (thereof) (of % in excess thereof).
(One Certificate of each Class may be issued in a different minimum
denomination or minimum percentage interest in order to accommodate the
remainder of such Class.)

         Distributions of interest and principal in reduction of Certificate
Principal Amount to Holders of each Class of Regular Certificates will be made
monthly, to the extent of such Class's entitlement thereto as described herein
under "--Distributions," on the th day of each month or, if such day is not a
Business Day (as defined below), on the succeeding Business Day (each, a
"Distribution Date"), commencing in 199_. The Class ( ) and Class R
Certificates are subordinated in certain respects to the Class ( ) Certificates
to the extent described herein; and the Class R Certificates are subordinated
to the Regular Certificates as described herein.

         A "Business Day" is a day other than Saturday, Sunday, or a day on
which banking institutions in the State of or The City of New York are
authorized or obligated by law or executive order to be closed.

                        DELIVERY, FORM AND DENOMINATION

         (No Person acquiring an Offered Certificate that is in book-entry form
(each, a "beneficial owner") will be entitled to receive a physical certificate
representing such Certificate. Instead, the Offered Certificates will be
registered in the name of a nominee of The Depository Trust Company (together
with any successor depository selected by the Depositor, the "Depository"), and
beneficial interests therein will be held by investors through the book-entry
facilities of the Depository, as described herein, in minimum denomination of
$1,000 initial Certificate Principal Amount and in integral multiples thereof.
The Depositor has been informed by the Depository that its nominee will be Cede
& Co. Accordingly, Cede & Co. is expected to be the holder of record of any
Offered Certificates that are in book-entry form.

         Each beneficial owner's ownership of an Offered Certificate will be
recorded on the records of the brokerage firm, bank, thrift institution or
other financial intermediary (each, a "Financial Intermediary") that maintains
the beneficial owner's account for such purpose. In turn, the Financial
Intermediary's ownership of such Offered Certificate will be recorded on the
records of the Depository (or of a participating firm that acts as agent for
the Financial Intermediary, whose interest will in turn be recorded on the
records of the Depository, if the beneficial owner's Financial Intermediary is
not a Depository participant). Therefore, the beneficial owner must rely on the
foregoing procedures to evidence its beneficial ownership of such an Offered
Certificate. Beneficial ownership of an Offered Certificate may only be
transferred in compliance with the procedures of such Financial Intermediaries
and Depository participants.

         The Depository, which is a New York-chartered limited purpose trust
company, performs services for its participants, some of whom (and/or their
representatives) own the Depository. In accordance with its normal 


                                     S-22
<PAGE>

procedure, the Depository is expected to record the positions held by each 
Depository participant in the Offered Certificates, whether held for its own 
account or as a nominee for another Person. In general, beneficial ownership of
Offered Certificates will be subject to the rules, regulations and procedures 
governing the Depository and Depository participants as are in effect from time
to time.

         The Depository, or its nominee as record holder of the Offered
Certificates, will be recognized by the Depositor and the Trustee as the owner
of the Offered Certificates for all purposes, including notices and consents.
In the event of any solicitation of consents from or voting by
Certificateholders pursuant to the Agreement, the Trustee may establish a
reasonable record date and give notice of such record date to the Depository.
In turn, the Depository will solicit votes from the beneficial owners in
accordance with its normal procedures, and the beneficial owners will be
required to comply with such procedures in order to exercise their voting
rights through the Depository.

         Distributions of principal of and interest on the Offered Certificates
will be made on each Distribution Date to the Depository or its nominee. The
Depository will be responsible for crediting the amount of such payments to the
accounts of the applicable Depository participants in accordance with the
Depository's normal procedures. Each Depository participant will be responsible
for disbursing such payments to the beneficial owners for which it is holding
Offered Certificates and to each Financial Intermediary for which it acts as
agent. Each such Financial Intermediary will be responsible for disbursing
funds to the beneficial owners of the Offered Certificates that it represents.

         The information herein concerning the Depository and its book-entry
system has been obtained from sources believed to be reliable, but the
Depositor takes no responsibility for the accuracy of completeness thereof.)

         (The Class Certificates will be issued in fully registered form in
minimum denominations of $_____ and integral multiples of $_____ in excess
thereof. The Class Certificates may be transferred or exchanged at the
corporate trust office of the Trustee without the payment of any service
charge, other than any tax or governmental charge payable in connection
therewith.)

                                 DISTRIBUTIONS

                     (SUBJECT TO REVISION FOR EACH SERIES.)

                                   GENERALLY

         As more fully described below, distributions of principal and interest
on the Regular Certificates will be made on each Distribution Date in an
aggregate amount, to the extent funds are available therefor from payments on
the Mortgage Loans ((net of certain reimbursements to the Reserve Fund) and
draws on the Reserve Fund), equal to the sum of the Optimal Available Funds for
the Mortgage Loan Groups, (net of certain reimbursements to the Reserve Fund,)
plus the Basis Risk Reserve Fund Draw Amount and certain past due amounts
together with interest thereon as described herein. Such amount will be
allocated among different Classes of such Certificates as described below under
"--Allocation Among Classes." Such distributions will be made on each
Distribution Date in accordance with the Agreement to each Certificateholder of
record on the related Record Date. For each Distribution Date, the "Record
Date" is the close of business on the last Business Day of the month preceding
the month in which such Distribution Date occurs, in the case of the Fixed Rate
Certificates (and the Class ( ) Certificates), and the 15th day of the calendar
month in which such Distribution Date occurs (or, if such 15th day is not a
Business Day, the preceding Business Day), in the case of the (Class
Certificates) (Floating Rate Certificates).

         On each Distribution Date, the Trustee will determine the Optimal
Available Funds for each Mortgage Loan Group and will also determine the funds
received with respect to each Mortgage Loan Group then in the Collection
Account and available for distribution (the "Group Available Funds") for such
Mortgage Loan Group. The Group Available Funds for any Mortgage Loan Group may
be less than receipts on the Mortgage Loans (excluding Amounts Held for Future
Distribution (as defined below)) as the result of, among other things, payment
of certain servicing fees and expenses therefrom (and reimbursements to the
Reserve Fund made therefrom for advances of delinquent Mortgage Loan payments)
(, Senior Lien Advances) and for payments received on a Discounted Mortgage
Loan after its Scheduled Principal Balance has been reduced to zero as
described herein.



                                     S-23
<PAGE>

         To the extent the aggregate Group Available Funds of the Mortgage Loan
Groups are insufficient to make a distribution in full of the aggregate Optimal
Available Funds of the Mortgage Loan Groups, the Master Servicer will draw on
the Collection Account, as directed by the Trustee, up to the amount of any
additional funds held in such account as of the Distribution Date for
distribution on a future Distribution Date ("Amounts Held for Future
Distribution") and the Trustee will draw on the Reserve Fund in respect of
delinquencies and defaults on such Mortgage Loans in the amount described
herein (the "Credit Reserve Fund Draw Amount"), which amounts will be allocated
between the Mortgage Loan Groups as described herein. In addition, certain
shortfalls due to Basis Risk may be covered by Basis Risk Reserve Fund Draw
Amounts as described under "--Basis Risk" herein. The Group Available Funds for
each Mortgage Loan Group, together with any Amounts Held for Future
Distribution, Credit Reserve Fund Draw Amounts and Basis Risk Reserve Fund Draw
Amounts allocated to such Mortgage Loan Group, represent the full amount
available for distribution on a given Distribution Date with respect to such
Mortgage Loan Group (the "Available Distribution Amount" for such Mortgage Loan
Group).

         The "Optimal Available Funds" for each Mortgage Loan Group for any
Distribution Date will equal the sum of (i) the Optimal Mortgage Loan Interest
for such Mortgage Loan Group and (ii) the Optimal Mortgage Loan Principal for
such Mortgage Loan Group.

         The "Optimal Mortgage Loan Interest" for each Mortgage Loan Group on
any Distribution Date will equal (x) the aggregate, for all Mortgage Loans in
such Mortgage Loan Group, of interest then distributable with respect to each
such Mortgage Loan, in each case equal to interest accrued at the Mortgage
Interest Rate of such Mortgage Loan, net of the applicable Servicing Fee Rate
(the "Net Mortgage Interest Rate") ((or, with respect to a Discounted Mortgage
Loan which has been modified to change the Mortgage Interest Rate, the
applicable Assumed Net Mortgage Interest Rate)) from the Due Date for such
Mortgage Loan in the second preceding Due Period to the Due Date in the Due
Period immediately preceding such Distribution Date on the Scheduled Principal
Balance thereof as of the second preceding Determination Date (as defined
herein), less any Prepayment Interest Shortfall (as defined herein) allocable
thereto or plus any Excess Prepayment Interest allocable thereto, as the case
may be, less (y) any Deferred Interest with respect to such Mortgage Loan
Group.

         The "Optimal Mortgage Loan Principal" for each Mortgage Loan Group on
any Distribution Date will equal the sum, for all Mortgage Loans in such
Mortgage Loan Group, of:

         (i) the principal component of all scheduled Monthly Payments (other
than Balloon Payments) which become due during the related Due Period on the
related Mortgage Loans (other than Simple Interest Loans and Discounted
Mortgage Loans),

         (ii) the principal component of all Assumed Scheduled Payments deemed
to become due during the related Due Period with respect to any related Balloon
Mortgage Loan (other than a Discounted Mortgage Loan) that is delinquent in
respect of its Balloon Payment, including any Matured Performing Mortgage Loan,

         (iii) the Scheduled Principal Balance of each related Mortgage Loan as
of the Determination Date in the month preceding the month in which such
Distribution Date occurs which either was repurchased, was sold or became a
liquidated Mortgage Loan during the related Prepayment Period, (iv) to the
extent not included in the preceding clause (ii), the principal component of
all Balloon Payments on any related Mortgage Loan, up to the Scheduled
Principal Balance thereof, received during the related Prepayment Period,

         ((v) the portion of each payment of any Simple Interest Loan (other
than a Discounted Mortgage Loan which is a Simple Interest Loan) attributable
to principal received during the related Prepayment Period,)

         (vi) to the extent not included in the preceding clause (iii), all
other full or partial prepayments of principal or other recoveries allocable to
principal (including the principal portion of any payments made by the
Depositor as the result of breaches of representations or warranties of the
Depositor with respect to the Mortgage Loans) in excess of the principal
portion of any related Monthly Payment ("Principal Prepayments"), of any
related Mortgage Loan other than a Simple Interest Loan up to the Scheduled
Principal Balance thereof, received in the related Prepayment Period,



                                     S-24
<PAGE>

         (vii) the portion of any scheduled Monthly Payment or Assumed
Scheduled Payment, net of any applicable Workout Fee, which became due during
the related Due Period on any related Discounted Mortgage Loan which is in
excess of the sum of (i) one month of interest at the Assumed Net Mortgage
Interest Rate on the Scheduled Principal Balance thereof and (ii) the servicing
fee for such month at the Servicing Fee Rate on the actual principal balance
thereof, but not in excess of the Scheduled Principal Balance thereof,

         (viii) the excess, if any, of (x) the Scheduled Principal Balance of
any related Discounted Mortgage Loan on the related Determination Date, after
taking into account amounts included in the preceding clause (vii), over (y)
the actual principal balance of such Discounted Mortgage Loan,

         (ix) the amount of any Deficient Valuation and the present value of
any Debt Service Reduction with respect to any related Mortgage Loan, up to the
Scheduled Principal Balance thereof, occurring in the related Prepayment
Period, and

         (x) the amount of certain payments required in connection with
modifications of Mortgage Loans and foreclosure or other acquisitions of
Mortgaged Properties as described under "--Reserve Fund" herein and "SERVICING
OF THE MORTGAGE LOANS -- Modification, Waivers and Amendments" in the
Prospectus.

         For each Distribution Date, the "Due Period" is the period commencing
on the second day of the month preceding the month in which such Distribution
Date occurs and ending on (and including) the first day of the month in which
such Distribution Date occurs. In the case of the first Distribution Date, the
Due Period will be 2 through 1, 199__. For each Distribution Date, the
"Prepayment Period" is the period commencing immediately following the second
preceding Determination Date (or the Cut-Off- Date, in the case of the first
Distribution Date) and ending on the Determination Date in the month in which
such Distribution Date occurs. In the case of the first Distribution Date, the
Prepayment Period will be 1 through, 199__. As to each Mortgage Loan and any
Distribution Date, the due date (the "Due Date") is the day of the month in the
related Due Period on which a Monthly Payment or Balloon Payment is due (or, in
the case of a Non-Monthly Payment Loan (as defined below), deemed to be due)
(without giving effect to any grace period), except that with respect to
Mortgage Loans which by their terms accrue interest in advance rather than in
arrears, the Due Date for the interest portion of each Monthly Payment will be
deemed to be the date one month after the date such payment is actually due.
The determination date (the "Determination Date") is the 15th day (or if such
date is not a Business Day, the preceding Business Day) of the month in which
the related Distribution Date occurs. With respect to any Mortgage Loan and any
Due Period, the "Monthly Payment" is the scheduled monthly payment of principal
and interest, excluding any Balloon Payment, on such Mortgage Loan which is
payable by a Borrower in such Due Period under the related Note or, in the case
of any REO Mortgage Loan, which would otherwise have been payable under the
Note relating to such REO Mortgage Loan, determined in accordance with the
Agreement, except that (x) with respect to any Mortgage Loan which by its terms
pays interest in advance of its accrual rather than in arrears, the Monthly
Payment is the scheduled monthly payment of principal, excluding any Balloon
Payment, due in such Due Period and the scheduled monthly payment of interest
due in the preceding Due Period, and (y) with respect to any Mortgage Loan as
to which the related Borrower is not required to make payments monthly under
the terms of the related Note (a "Non-Monthly Payment Loan"), the Monthly
Payment in any month is interest accrued thereon from the Due Date in the
preceding Due Period to the Due Date in such current Due Period and principal
(other than a Balloon Payment) due in such Due Period. With respect to a
Non-Monthly Payment Loan, the Monthly Payment in respect of such loan is deemed
to be due the same day of each Due Period as the day in the month in which
payments in respect of such loan are actually due.)

         As referred to herein, the "Scheduled Principal Balance" of a Mortgage
Loan (other than a Discounted Mortgage Loan) with respect to any Determination
Date is equal to the principal balance of such Mortgage Loan as of the Due Date
of such Mortgage Loan occurring in the Due Period relating to such
Determination Date, after giving effect to (a) any principal repayments or
other unscheduled recoveries of principal, any Balloon Payments and, as to
Simple Interest Loans, any payments attributable to principal received on or
prior to such Determination Date, (b) the Deferred Interest, if any, added to
the principal balance of such Mortgage Loan on or before such Due Date, (c)
except in the case of any Simple Interest Loan, any payment in respect of
principal, if any, due on or before such Due Date (other than a Balloon
Payment, but including the principal portion of any Assumed Scheduled Payment,
if applicable), irrespective of any delinquency in payment by the Borrower, and
(d) any adjustment resulting from a Deficient Valuation of in connection with a
Debt Service Reduction resulting from any bankruptcy or similar proceeding.
With respect to any Discounted Mortgage Loan, the "Scheduled Principal Balance"
thereof shall be determined as described 


                                     S-25
<PAGE>

herein. As indicated above, the Scheduled Principal Balance of a Mortgage Loan
that is delinquent as to its Balloon Payment and that has not yet been the
subject of a modification as a consequence thereof will be calculated with
reference to the Assumed Scheduled Payments in respect of such Mortgage Loan.
As referred to herein, "Assumed Scheduled Payment" means, with respect to any
Balloon Mortgage Loan that is delinquent in respect of its Balloon Payment
(including any REO Mortgage Loan for which the related Note had provided for a
Balloon Payment), an amount deemed to be due for such Balloon Mortgage Loan on
each Distribution Date after the related Due Date, which will generally be
equal to the Monthly Payment that would otherwise have been due thereon during
the related Due Period had such Balloon Payment not become due, determined as
provided in the Agreement.

         The Scheduled Principal Balance of any REO Mortgage Loan will be
determined in the manner described above as if the related Note had remained
outstanding. Net proceeds received in respect of any REO Property in excess of
the scheduled Monthly Payments or Assumed Scheduled Payments that are assumed
to remain in effect will be treated as prepayments of the Scheduled Principal
Balance of the related REO Mortgage Loan.

         In the event that a Mortgage Loan is prepaid in full, the principal
portion of any Monthly Payment received during the Prepayment Period in which
such prepayment is received but after the Due Period which ended during such
Prepayment Period shall be treated as part of such principal prepayment.

                                    INTEREST

         Interest will accrue on each Class of Regular Certificates at the
applicable rate (the "Pass-Through Rate") set forth below. The interest
distributable on the Classes of Fixed Rate Certificates (and the Class ( )
Certificates) on each Distribution Date will be the interest accrued at the
applicable Pass-Through Rate for each such Class on the applicable Certificate
Principal Amount thereof during each one-month period beginning on the first
day of the month preceding the month in which each Distribution Date occurs,
commencing 1, 199__, less any Deferred Interest allocable thereto. The interest
distributable on the (Class ( ) Certificates) (Floating Rate Certificates) on
each Distribution Date will be the interest accrued at the Pass-Through Rate
for such Certificate Principal Amount thereof during each one-month period
commencing on the 25th day of each month (or, in the case of the first
Distribution Date, on , 199__) and ending on the 24th day of the month in which
the Distribution Date occurs, less any Deferred Interest allocable thereto. The
monthly periods during which interest accrues on any Class of Regular
Certificates are each referred to herein as an "Interest Accrual Period" for
such Class. See "YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS" for a
discussion of the effect on the yield to Certificateholders arising from the
lag between the accrual of interest on the Certificates and the distribution
thereof.

         The "Certificate Principal Amount" of any Class of Regular
Certificates with respect to any Distribution Date is the Certificate Principal
Amount of such Class as of the Cut-Off-Date plus all Deferred Interest
allocated to such Class on previous Distribution Dates (as described herein
under "--Allocation of Deferred Interest"), less all amounts previously
distributed to such Class in reduction of Certificate Principal Amount as
described below and all reductions without distribution as provided herein.

         (Interest Only Certificates are assigned a "Notional Amount" which is
used solely for convenience in expressing the calculation of interest and for
certain other purposes. Reference to the Notional Amount of the Class ( )
Certificates is solely for convenience of certain calculations and does not
represent a right to receive any distributions allocable to principal.)

         The amount of interest distributable with respect to any Class of
Regular Certificates during an Interest Accrual Period will be reduced by the
amount of any Deferred Interest allocated to such Class on the Distribution
Date immediately following such Interest Accrual Period as described herein
"--Allocation of Deferred Interest."

         Interest which accrues on each Class of Regular Certificates will be
calculated on the assumption that distributions on a Distribution Date in
reduction of Certificate Principal Amount thereof were made, and increases in
Certificate Principal Amount in connection with Deferred Interest allocated
thereto were added, at the end of the preceding Interest Accrual Period rather
than on the Distribution Date when actually made or added. Interest on each
Class of Regular Certificates will be calculated on the basis of a 360-day year
consisting of twelve 30-day months.



                                     S-26
<PAGE>

     The amount of interest accrued on any Class of Regular Certificates during
an Interest Accrual Period ("Accrued Certificate Interest"), net of any
Deferred Interest allocated thereto, is referred to herein as the "Class
Interest Distribution Amount" with respect to such Interest Accrual Period.
Such amount will be distributed to the Holders of such Class, to the extent the
Available Distribution Amounts are sufficient therefor after application in
accordance with the priorities set forth herein under "--Allocation Among
Classes," on the Distribution Date immediately following such Interest Accrual
Period.

(INSERT ONE OF THE FOLLOWING PARAGRAPHS
FOR EACH CLASS, AS APPLICABLE:)

     During each Interest Accrual Period for the Class ( ) Certificates, the
Pass-Through Rate for the Class ( ) Certificates will be a per annum rate equal
to ( )% (the "Class ( ) Pass-Through Rate").

     (During the initial Interest Accrual Period for the Class ( )
Certificates, the Pass-Through Rate for the Class ( ) Certificates will be ( )%
per annum. During each subsequent Interest Accrual Period for the Class ( )
Certificates, the Pass-Through Rate for the Class ( ) Certificates will be a
per annum rate equal to the lesser of (a) (LIBOR) (COFI) (other Index) as of
the (LIBOR) (COFI) (other Index) Determination Date preceding such Interest
Accrual Period plus ( )% per annum, and (b) ( )% (the "Class ( ) Pass-Through
Rate").)

ALLOCATION OF DEFERRED INTEREST

     The aggregate amount of interest required to be paid to the Holders of
Fixed Rate Certificates on any Distribution Date will be decreased by the
aggregate amount of negative amortization added to the principal balances of
the Mortgage Loans in the related Mortgage Loan Group (or in the case of
Discounted Mortgage Loans, added to the Scheduled Principal Balances thereof)
in the related Due Period up to the amount of interest accrued on the Fixed
Rate Certificates during the related Interest Accrual Period, and the amount
thereof will be added to the Certificate Principal Amount of the Fixed Rate
Certificates as provided in the Agreement. Such reduction in the amount of
interest to be paid to the Fixed Rate Certificates will be allocated, pro rata,
among the Classes thereof, based on their Accrued Certificate Interest. In
certain circumstances, including in the remote event that the aggregate amount
of negative amortization added to the Mortgage Loans in a Mortgage Loan Group
in any Due Period exceeds the amount of interest accrued on the Fixed Rate
Certificates during the related Interest Accrual Period, such excess will be
allocated to other Classes of Regular Certificates; any remaining excess will
reduce excess interest available to make principal payments on the Regular
Certificates.

BASIS RISK

     (The Pass-Through Rates on the Classes of Regular Certificates will
initially correspond to net mortgage interest rates on an equivalent principal
balance of Mortgage Loans with comparable types of interest rates. That is, the
aggregate Certificate Principal Amount of the Class Certificates will initially
be approximately equal to the aggregate Scheduled Principal Balance of the
Group Mortgage Loans (which Mortgage Loans bear (fixed interest rates or
adjustable interest rates subject to high floors) (interest based on COFI)
(interest based on LIBOR) (interest at adjustable interest rates based on a
variety of Indexes)). Such correspondence is expected to vary over time,
however, because of (dependent on structure of the deal).

     The Pass-Through Rates of the Class ( ) and Class ( ) Certificates are
based upon the value of indexes (LIBOR and COFI) which may be different from
the value of the Indexes (as defined herein) upon which the Mortgage Interest
Rates of the Group and Group Mortgage Loans are based (either as a result of
the use of a different index, rate determination date, rate adjustment date or
rate cap or floor). Consequently, the interest which becomes due on such
Mortgage Loans (net of the servicing fees) during any Due Period may not equal
the amount of interest that would accrue at LIBOR or COFI plus the applicable
margin on the Class ( ) or Class ( ) Certificates, subject to the cap thereon,
during the related Interest Accrual Period. In addition, because interest
accruing on the Regular Certificates will be calculated on the basis of a
360-day year consisting of twelve 30-day months, while the Mortgage Loans may
accrue interest on another basis (such as the actual number of days in the
related interest accrual period), the interest which becomes due on the
Mortgage Loans (net of servicing fees) on Due Dates therefor occurring in any
Due Period may be less than the amount of interest which accrues on a
corresponding Certificate Principal Amount of the Regular Certificates during
the related Interest Accrual Period. In addition, with respect to the Class ( )
Certificates, LIBOR


                                     S-27
<PAGE>

and Indexes applicable to the Mortgage Loans included in Mortgage Loan Group
and may respond to different economic and market factors, and there is no
necessary correspondence between them. Thus, it is possible, for example, that
LIBOR may rise during periods in which one or more of the Indexes are stable or
are falling or that, even if both LIBOR and the Indexes rise during the same
period, LIBOR may rise much more rapidly than the Indexes. Furthermore, certain
Group (1F) Mortgage Loans bear fixed Mortgage Interest Rates (and certain Group
(1A) Mortgage Loans are subject to Floor Interest Rates which, if reached,
would result in Net Mortgage Interest Rates) that are lower than the weighted
average of the Pass-Through Rates of the Fixed Rate Certificates. Finally, a
number of the adjustable rate Group (1A) and Group Mortgage Loans are
convertible to a fixed Mortgage Interest Rate, which rate (net of servicing
fees) may be lower at any time than the weighted average of the Pass-Through
Rates of the related Classes of Certificates.

     Any shortfall in accrued interest at the Net Mortgage Interest Rates on
the Mortgage Loans in relation to accrued interest at the respective
Pass-Through Rates on the Regular Certificates(, net of principal due or
received on such Mortgage Loans and applied to interest on such Regular
Certificates,) is referred to herein as a "Basis Risk Shortfall." (The Reserve
Fund will be available to cover any remaining Basis Risk Shortfall, except in
certain cases to the extent the balance in the Reserve Fund has been reduced to
the Liquidity Amount.)

     If a Borrower prepays a Mortgage Loan in whole or part, makes a Balloon
Payment or makes any payment of principal on a Simple Interest Loan during a
Prepayment Period and the date on which such payment is made (or, with respect
to a Balloon Payment, the date through which interest thereon accrues) is prior
to the Due Date for such Mortgage Loan in the related Due Period, the amount of
interest (net of servicing fees) which accrues on the amount of such principal
payment will be less than the corresponding amount of interest accruing on the
Regular Certificates. If such a principal payment occurs during a Prepayment
Period but after the Due Date for such Mortgage Loan in the related Due Period
(or, with respect to a Balloon Payment, the date through which interest thereon
accrues), the amount of interest (net of servicing fees) which accrues on the
amount of such principal payment will exceed the corresponding amount of
interest accruing on the Regular Certificates. To the extent that such excesses
for all Mortgage Loans exceed such shortfalls for all Mortgage Loans as of any
Determination Date, such net amount ("Excess Prepayment Interest") will be
applied as described below under "--Allocation Among Classes." To the extent
that such shortfalls for all Mortgage Loans exceed such excesses for such
Mortgage Loans as of any Determination Date, such net shortfall (a "Prepayment
Interest Shortfall") will reduce funds available from Mortgage Loan payments
for distribution to Certificateholders.

     The Regular Interests corresponding to each Class of the Regular
Certificates bear interest at a rate (each, a "REMIC Pass-Through Rate") equal
to the Pass-Through Rate for the related Class of Regular Certificates if no
Basis Risk Shortfall exists, and otherwise bear interest at a REMIC
Pass-Through Rate equal to the lesser of (a) the Pass-Through Rate for the
related Class of Regular Certificates and (b) the weighted average of the Net
Mortgage Interest Rates, weighted on the basis of the actual principal balances
of the Mortgage Loans in selected Mortgage Loan Groups. (specific deal approach
to Basis Risk to be described, including any draws on a reserve fund)

     As of the Cut-Off-Date, the difference between the Weighted Average Net
Mortgage Interest Rate of the Mortgage Loans in Mortgage Loan Group 1 and the
Pass-Through Rates of the Fixed Rate Certificates (such difference from time to
time, the "Group 1 Interest Rate Spread") was at least % per annum, and the
difference between (x) the weighted average of the Net Mortgage Interest Rates
which would be applicable on each Mortgage Loan in Mortgage Loan Group 1 if
each Group (1A) Mortgage Loan adjusted immediately to its Index plus its
Margin, subject only to its lifetime maximum Mortgage Interest Rate or Floor
Interest Rate, and (y) the Pass-Through Rates of the Fixed Rate Certificates
(the "Group 1 Fully Indexed Interest Rate Spread") was at least % per annum.
However, there can be no assurance that such positive Group 1 Interest Rate
Spread or Group 1 Fully Indexed Interest Rate Spread will not decline to zero
or become negative. (Repeat description of spreads for other Mortgage Loan
Group.)

     Interest due on the Mortgage Loans at their respective Mortgage Interest
Rates (net of applicable servicing fees) which is in excess of interest on the
Regular Certificates at their respective Pass-Through Rates will be applied to
principal on the Regular Certificates as described under "--Allocation Among
Classes" herein, creating overcollateralization. Any such overcollateralization
will reduce the likelihood of Basis Risk Shortfalls, since interest will then
accrue on the Mortgage Loans on a higher balance than the aggregate Certificate
Principal Amount on which interest on the Regular Certificate accrues. While
the Group 1 Interest Rate Spread may change over time, and may in 


                                     S-28
<PAGE>

fact be negative due to disproportionate prepayments of Group 1 Mortgage Loans 
with higher fixed Net Mortgage Interest Rates, any such reduction or negative 
spread may be offset by the effects of overcollateralization.

DETERMINATION OF LIBOR

     On the second LIBOR Business Day preceding each Distribution Date (each
such date, a "LIBOR Determination Date"), commencing in 199__, the Trustee will
determine the London interbank offered rate for (one-month) U.S. dollar
deposits ("LIBOR") for the next Interest Accrual Period for the (Class ( )
Certificates) (Floating Rate Certificates) on the basis of the offered rates of
the Reference Banks for (one-month) U.S. dollar deposits, as such rates appear
on the Reuters Screen LIBO Page, as of 11:00 a.m. (London time) on such LIBOR
Determination Date. "LIBOR Business Day" means a day on which banks are open
for dealing in foreign currency and exchange in London; "Reuters Screen LIBO
Page" means the display designated as page "LIBO" on the Reuters Monitor Money
Rates Service (or such other page as may replace the LIBO page on that service
for the purpose of displaying London interbank offered rates of major banks);
and "Reference Banks" means leading banks engaged in transactions in Eurodollar
deposits in the international Eurocurrency market (i) with an established place
of business in London, (ii) not controlling, under the control of or under
common control with, the Depositor, (iii) whose quotations appear on the
Reuters Screen LIBO Page on the LIBOR Determination Date in question and (iv)
which have been designated as such from time to time by the Trustee. The
initial Reference Banks will be. If any of the initial Reference Banks should
be removed from the Reuters Screen LIBO Page or in any other way fail to meet
the qualifications of a Reference Bank, the Trustee will use its best efforts
to designate alternative Reference Banks.

         On each LIBOR Determination Date, LIBOR for the next Interest Accrual
Period for the (Class ( ) Certificates) (Floating Rate Certificates) will be
established by the Trustee as follows:

         (a) If on any LIBOR Determination Date two or more Reference Banks
provide such offered quotations, LIBOR for the next Interest Accrual Period for
such Certificates shall be the arithmetic mean of such offered quotations
(rounded upwards if necessary to the nearest whole multiple of 1/16%).

         (b) If on any LIBOR Determination Date fewer than two Reference Banks
provide such offered quotations, LIBOR for the next Interest Accrual Period for
such Certificates shall be the higher of (x) 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 Trustee determines
to be (i) the arithmetic mean (rounded upwards if necessary to the nearest
whole multiple of 1/16%) of the (one-month) U.S. dollar lending rates which
three New York City banks selected by the Trustee after consultation with the
Depositor 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 Trustee can determine no such arithmetic mean, (ii) the lowest
(one-month) U.S. dollar lending rate which the New York City banks so selected
by the Trustee are quoting on such LIBOR Determination Date to leading European
banks.

         (c) If on any LIBOR Determination Date the Trustee is required but
unable to determine LIBOR in the manner provided in paragraphs (a) and (b)
above, LIBOR for the next Interest Accrual Period for such Certificates shall
be LIBOR as determined on the previous LIBOR Determination Date or, in the case
of the first LIBOR Determination Date, __%.

         The establishment of LIBOR on each LIBOR Determination Date by the
Trustee and the Trustee's calculation of the rate of interest applicable to the
(Class ( ) Certificates) (Floating Rate Certificates) for the related Interest
Accrual Period shall (in the absence of manifest error) be final and binding.
Each such rate of interest may be obtained by telephoning the Trustee at
(___)___-____.)

DETERMINATION OF COFI

         The amount of interest which will accrue in respect of Class ( )
Certificates during each related Interest Accrual Period will be determined on
the basis of COFI available on the tenth day of the month preceding the month
in which the related Distribution Date occurs (each such date, a "COFI
Determination Date"). For example, if COFI relating to 199__ is announced on or
before ______10, 199__, interest on the Class ( ) Certificates for the
Distribution Date in 199__ will be based on COFI for 199__. COFI is the monthly
weighted average cost of funds for savings institutions the home offices of
which are located in Arizona, California or Nevada that are member institutions
of the 


                                     S-29
<PAGE>

Eleventh Federal Home Loan Bank District as computed from statistics
tabulated and published by the Federal Home Loan Bank of San Francisco (the
"FHLBSF"). The FHLBSF publishes COFI in its monthly Information Bulletin. Any
individual may request receipt by mail of Information Bulletins by writing the
Federal Home Loan Bank of San Francisco, P.O. Box 7948, 600 California Street,
San Francisco, California 94120, or by calling (415) 616-1000. In the event
that the FHLBSF ceases to publish COFI, interest on the Class ( ) Certificates
will accrue on the basis of the alternate index established by FNMA in
connection with its program for guaranteed mortgage pass-through certificates
that bear interest based on COFI.

         The determination of COFI on each COFI Determination Date by the
Trustee and the Trustee's calculation of the rate of interest applicable to the
Class ( ) Certificates for the related Interest Accrual Period shall (in the
absence of manifest error) be final and binding. Each such rate of interest may
be obtained by telephoning the Trustee at (___)___-____.) Unlike most other
interest rate measures, COFI does not necessarily reflect current market rates.
A number of factors affect the performance of COFI which may cause COFI to move
in a manner different from indices tied to specific interest rates, such as
United States Treasury Bills or LIBOR. Because of the various maturities of the
liabilities upon which COFI is based (which may be more or less sensitive to
market interest rates), COFI may not necessarily reflect the average prevailing
market interest rates on new liabilities of similar maturities. Additionally,
COFI may not necessarily move in the same direction as market interest rates,
because as longer term deposits or borrowing mature and are renewed at
prevailing market interest rates, COFI is influenced by the differential
between the prior rates on such deposits or borrowings and the cost of new
deposits or borrowings. Moreover, COFI represents the average cost of funds for
Eleventh District member institutions for the month prior to the month in which
COFI is generally announced, which is in turn the month prior to the Interest
Accrual Period. Movement of COFI, as compared to other indices tied to specific
interest rates, may also be affected by changes instituted by FHLB San
Francisco in the method it uses to calculate COFI.

           DISTRIBUTIONS IN REDUCTION OF CERTIFICATE PRINCIPAL AMOUNT

         The Available Distribution Amounts for any Distribution Date will be
allocated among the Classes of the Certificates, resulting in distributions in
reduction of Certificate Principal Amount, as described below under
"--Allocation Among Classes."

                   GROUP AVAILABLE FUNDS; RESERVE FUND DRAWS

         The "Group Available Funds" for each Mortgage Loan Group with respect
to any Distribution Date will equal (a) the amount on deposit in the Collection
Account with respect to the Mortgage Loans included in such Mortgage Loan Group
(other than any investment income earned thereon) as of the close of business
on the related Determination Date minus (b) the sum of (i) the portion of the
amount described in clause (a) hereof that represents Monthly Payments received
but due during any subsequent Due Period (or, with respect to Simple Interest
Loans, that represents interest accrued on the Scheduled Principal Balance
thereof after the Due Date in the related Due Period) and (ii) all other
amounts related to such Mortgage Loan Group (or, if not related to a particular
Mortgage Loan Group, as allocated to such Mortgage Loan Group pursuant to the
Agreement) either not required to be deposited by the Master Servicer in the
Collection Account or permitted or required to be withdrawn therefrom by the
Master Servicer pursuant to the Agreement (including, among other things,
servicing fees, reimbursement for certain expenses of the Master Servicer or
Special Servicer (and reimbursements to the Reserve Fund)).

         To the extent that Mortgage Loan payments that would have been
included in the Optimal Available Funds for any Mortgage Loan Group on any
Distribution Date have not been received by the close of business on the
related Determination Date, the shortfall between such Optimal Available Funds
and the Group Available Funds will be covered, to the extent funds are
sufficient therefor, first, from Amounts Held for Future Distribution
((limited, in the case of Mortgage Loan Group , to the Amounts Held for Future
Distribution received on Eligible Multifamily Mortgage Loans)), and second, to
the extent that such shortfall exceeds any such Amounts Held for Future
Distribution, from amounts drawn from the Reserve Fund as more fully described
herein. Notwithstanding the foregoing, so long as any related Class Certificate
remains outstanding, no such draw will be made which would reduce the balance
of the Reserve Fund below its Liquidity Amount, except to the extent required
to make the minimum distribution then required to be made on the Class
Certificates. To the extent Amounts Held for Future Distribution or amounts
drawn from the Reserve Fund are not sufficient to cover the full shortfalls for
all Mortgage Loan Groups, such amounts will be allocated pro rata (among) the
Mortgage Loan Groups based on the respective shortfalls in each group. With
respect 


                                     S-30
<PAGE>

to any Distribution Date and Mortgage Loan Group, the Group Available
Funds for such Mortgage Loan Group together with any such Amounts Held for
Future Distribution applied to cover shortfalls and amounts drawn from the
Reserve Fund with respect to such Mortgage Loan Group is referred to herein as
the "Available Distribution Amount" with respect to such Mortgage Loan Group.

                            ALLOCATION AMONG CLASSES

         On each Distribution Date, the Trustee will determine the Available
Distribution Amount for each Mortgage Loan Group. (To the extent the amount in
the Reserve Fund is less than the Liquidity Amount as described under "THE
TRUST FUND -- Enhancement -- Reserve Fund" draws on the Reserve Fund included
in the Available Distribution Amount will be limited.) So long as any Class
Certificates remain outstanding, such draws will be made only to the extent
required to assure that Holders of the Class Certificates receive their
required minimum distributions in full and no draws will be made on the Reserve
Fund for the benefit of the Holders of the Class Certificates. (Repeat Reserve
Fund draw limitations for succeeding Classes, as applicable.)

         On each Distribution Date, the aggregate of the Available Distribution
Amounts for Mortgage Loan Group (including Group Available Funds for each such
Mortgage Loan Group and Amounts Held for Future Distribution (to the extent
included therein as described above) and draws on the Reserve Fund as described
under "--Group Available Funds; Reserve Fund Draws" above allocated to such
Mortgage Loan Group) and any amounts from Mortgage Loan Groups and allocated
pursuant to the following priorities, as set forth below, will be distributed
in respect of each Class in the amounts (to the extent sufficient therefor),
and in the order of priority, as follows:

         First, to the Class Certificates in respect of interest, up to an
amount equal to the Class Interest Distribution Amount of such Class;

         Second, to the Class Certificates in respect of interest, up to an
amount equal to the Class Unpaid Interest Shortfall of such Class;

         Third, to the Class Certificates in reduction of the Certificate
Principal Amount thereof, in an amount equal to the Optimal Mortgage Loan
Principal for Mortgage Loan Groups and (until the Certificate Principal Amount
thereof has been reduced to zero);

         Fourth, to the Class Certificates in reduction of the Certificate
Principal Amount thereof until the Certificate Principal Amount thereof has
been reduced to zero, in an amount equal to any amounts previously
distributable under the preceding clause Third and not previously distributed
thereunder or under this clause Fourth;

         Fifth, so long as any Class Certificates remain outstanding, to the
Collateral Agent for deposit into the Reserve Fund, up to the amount
necessary(, after application of funds pursuant to clause of the priorities for
the Available Distribution Amount for Mortgage Loan Groups and ,) for the
balance of the Reserve Fund to equal the Liquidity Amount;

         (INSERT ADDITIONAL ALLOCATION RULES FOR EACH SERIES, AS APPLICABLE.)

         any remaining amounts to the Class R Certificates (whether or not the
Class Certificates remain outstanding).

         (Distributions pursuant to the preceding clauses will be paid from the
portion of the Available Distribution Amounts for Mortgage Loan Groups and
representing payments on Mortgage Loans other than Eligible Multifamily
Mortgage Loans and only thereafter from the portion thereof representing
payments on Eligible Multifamily Mortgage Loans, except that deposits to the
Reserve Fund pursuant to clauses___, ___, and ____ will be made first from the
remaining portion of the Available Distribution Amounts for Mortgage Loan
Groups and representing payments on Eligible Multifamily Mortgage Loans, and
only thereafter from the portion thereof representing payments on Mortgage
Loans other than Eligible Multifamily Mortgage Loans.)

         All of the foregoing determinations are made after increasing the
Certificate Principal Amounts of the Regular Certificates as a result of
allocations of Deferred Interest on such Distribution Date.



                                     S-31
<PAGE>

         (Notwithstanding the foregoing, on and after any Distribution Date on
which the aggregate Available Distribution Amount for Mortgage Loan Group and
is not sufficient to reduce the aggregate Certificate Principal Amount of the
Class __ and Class __ Certificates to an amount at least equal to the aggregate
Scheduled Principal Balance of the Mortgage Loans (less the Certificate
Principal Amount of the Class Certificates), then the portion of such aggregate
Available Distribution Amount allocable to the Class and Class Certificates in
the foregoing priorities will be distributed pro rata between the Class and
Class Certificates based on their outstanding Certificate Principal Amounts
rather than in accordance with the priorities that would otherwise apply.)

         As referred to herein, the "Class Unpaid Interest Shortfall" with
respect to any Class is the aggregate amount of interest that was distributable
to such Class on all preceding Distribution Dates less the aggregate amount
thereof actually distributed to such Class on all prior Distribution Dates plus
interest accrued thereon at the applicable Pass-Through Rate, compounded
monthly as of the end of each Interest Accrual Period, to the end of the
Interest Accrual Period preceding the Distribution Date when paid, including
any Uncovered Basis Risk Shortfall for such Class. All references in the
preceding clauses to an allocation on a pro rata basis will, unless otherwise
specified, mean an allocation pro rata on the basis of the maximum amount to
which each Class would be entitled under the applicable clause, assuming that
the Available Distribution Amounts were sufficient therefor.

                              CLASS R CERTIFICATES

         The Class R Certificates represent beneficial ownership of the
residual interest in the REMIC, subject to the obligation to make deposits into
the Reserve Fund in respect of Basis Risk Reserve Fund Draw Amounts as
described below under "--Regular Interests." The Class R Certificates will not
have a Certificate Principal Amount or a Pass-Through Rate assigned thereto and
will not be entitled to distributions of interest or in reduction of
Certificate Principal Amount. However, the Class R Certificates will be
entitled to receive any Available Distribution Amount remaining on any
Distribution Date after the Certificate Principal Amounts of all of the Regular
Certificates have been reduced to zero and also will be entitled to receive the
proceeds of the remaining assets of the Trust Fund, if any, after the
Certificate Principal Amounts of all of the Regular Certificates have been
reduced to zero.

                            EXAMPLE OF DISTRIBUTIONS

         The following chart sets forth an example of distributions on the
Regular Certificates for the Distribution Date occurring in 199__:

                                [CHART OMITTED]

(A)      The Due Period with respect to the Distribution Date. Monthly Payments
         (other than the principal component thereof for Simple Interest Loans)
         due during the Due Period and any Assumed Scheduled Payments deemed to
         be due during the Due Period will be available for distribution of
         principal 2 - and interest to Certificateholders on the Distribution
         Date to the extent the Available Distribution Amounts are sufficient
         therefor.

(B)      The Prepayment Period with respect to the Distribution Date. Balloon
         (15) Payments, Principal Prepayments and the principal component of
         Monthly Payments on Simple Interest Loans made during the Prepayment
         Period will be available for distribution of principal and interest to
         Certificateholders on the Distribution Date. (31)

(C)      Record Date for the Fixed Rate Certificates (and the Class
         Certificates). (15) C)

(D)      Determination Date; Record Date for the (Floating Rate Certificates)
         (Class Certificates).(25)

(E)      Distribution Date.

                                [CHART OMITTED]

(A)      Such payments will be deposited in the Collection Account following
         receipt by the Master Servicer for distribution to Certificateholders
         on the Distribution Date.

(B)      Such payments will be deposited in the Collection Account following
         receipt by the Master Servicer for distribution to Certificateholders
         on the Distribution Date.

(C)      Distributions on the Fixed Rate (and Class ( )) Certificates will be
         made on the Distribution Date to Certificateholders of record at the
         close of business on the last Business Day of the month prior to the

         occurs or, if such day is not a Business Day, the preceding Business
         Day.

(D)      As of the close of business on ________ (15), the amounts of principal
         and interest to be passed through to Certificateholders will be
         determined. Holders of Regular Certificates generally will be
         entitled, to the extent of available funds, to one month of interest
         as described under "--Distributions - -- Interest" and to principal as
         described under "--Distributions--Allocation Among Classes." Monthly
         Payments due during the Due Period, any Assumed Scheduled Payments
         deemed to be due during the Due Period and Balloon Payments, Principal
         Prepayments and the principal portion of payments on Simple Interest
         Loans received during the Prepayment Period will be deposited in the
         Distribution Account on the Master Servicer Remittance Date (to the
         extent funds available for withdrawal from the Collection Account
         and/or the Reserve Fund are sufficient therefor) for distribution to

                              OPTIONAL TERMINATION

         The Master Servicer, the Holders of the Class R Certificates, the
owner of the Reserve Fund or, if all Mortgage Loans are then Specially Serviced
Mortgage Loans, the Special Servicer, may effect a termination of the Trust
Fund on any Distribution Date after the date on which the aggregate Certificate
Principal Amount of the Regular Certificates is reduced to less than 10% of the
initial aggregate Certificate Principal Amount of the Regular Certificates, by
purchasing all the assets of the Trust Fund at a purchase price, payable in
cash, equal to the greater of: (x) 100% of the outstanding aggregate unpaid
principal balances of the Mortgage Loans plus accrued and unpaid interest
thereon to, but not including, the respective first Due Date following the Due
Period related to the Prepayment Period in which such repurchase occurs plus
the fair market value of all other property included in the Trust Fund; and (y)
the aggregate fair market value of the Mortgage Loans (including any other
property in the Trust Fund) as of the date of repurchase, determined as
provided in the Agreement. The proceeds of such sale will be treated as a
prepayment of the Mortgage Loans for purposes of distributions to
Certificateholders. Such sale will effect a termination of the Trust Fund and
an early retirement of the Regular Certificates. Such sale and consequent
termination of the REMIC must constitute a "qualified liquidation" of the REMIC
under Section 860F of the Code.

                                 THE TRUST FUND

GENERAL

         The Trust Fund will consist of the Mortgage Pool, together with the
payments thereon, and certain other assets, including (one or more reserve
funds established in respect of the Certificates) (the insurance policies) (an
irrevocable letter of credit) (a committed line of credit) (a repurchase
commitment) (a surety bond) ((the "Credit Enhancement") issued by (specify
provider of Credit Enhancement), as described herein.) (The amount available to
the Trustee under the Credit Enhancement is subject to reduction from time to
time as described herein.)

THE MORTGAGE COLLATERAL

         The Mortgage Collateral will consist of Mortgage Loans (and
participation interests in Mortgage Loans).



                                     S-35

          The Mortgage Pool will consist of one or more adjustable and fixed
rate, amortizing and Balloon Payment, recourse or non-recourse,
newly-originated or seasoned (conventional) mortgage loans(,) (and) Installment
Contracts for the sale of real estate) (and mortgage pass-through
certificates).

         Each Mortgage Loan included in the Trust Fund ((or, in the case of a
mortgage pass-through certificate, each underlying mortgage loan)) is evidenced
by a Note and is secured primarily by a first Mortgage on, or is an Installment
Contract for the sale of, a fee simple or leasehold interest in (multifamily
residential (rental) properties) (and) (cooperatively owned multifamily
properties) consisting of five or more dwelling units, commercial real estate
properties (, mixed multifamily/commercial properties). The commercial real
estate properties may include office buildings, retail buildings, warehouses,
hotels and motels, vehicle service facilities, industrial buildings, medical
buildings, mobile home parks, nursing homes, shopping centers, garages and a
variety of other commercial properties. The Mortgaged Properties are located in
one of approximately states (and the District of Columbia).

         (In the case of Mortgage Loans having an aggregate Scheduled Principal
Balance of $, representing % of the Mortgage Pool by Scheduled Principal
Balance as of the Cut-Off-Date, the Mortgage Loan is secured by a second
Mortgage; (ii) in the case of Mortgage Loans having an aggregate Scheduled
Principal Balance of $, representing % of the Mortgage Pool by Scheduled
Principal Balance as of the Cut-Off-Date, the Mortgage Loan is secured by a
third Mortgage; (iii) in the case of Mortgage Loans having an aggregate
Scheduled Principal Balance of $, representing less than % of the Mortgage Pool
by Scheduled Principal Balance as of the Cut-Off-Date, the Mortgage Loan is
secured by a lien on a Mortgaged Property more junior than a third Mortgage;
and (iv) in the case of Mortgage Loans having an aggregate Scheduled Principal
Balance of $, representing % of the Mortgage Pool by Scheduled Principal
Balance as of the Cut-Off-Date, the Mortgage Loan is secured by liens on
Mortgaged Properties for which the lien position is not available).)

         Mortgage Loans having an aggregate Scheduled Principal Balance of
approximately $, representing % of the aggregate Scheduled Principal Balance of
the Mortgage Loans as of the Cut-Off-Date, will be Specially Serviced Mortgage
Loans as of the Closing Date if no Monthly Payments are received on such
Mortgage Loans from the Cut-Off-Date to the Closing Date because each of such
Mortgage Loans will then have a payment which is more than 60 days past due. of
these Mortgage Loans, having an aggregate Scheduled Principal Balance as of the
Cut-Off-Date of $ are among the 50 largest Mortgage Loans in the Mortgage Pool.

         (In addition, Mortgage Loans having an aggregate Scheduled Principal
Balance of the Mortgage Loans as of the Cut-Off-Date, are Matured Performing
Mortgage Loans. Such Mortgage Loans will be Specially Serviced Mortgage Loans
as of the Closing Date. of these Mortgage Loans, having an aggregate Scheduled
Principal Balance as of the Cut-Off-Date of $, are among the 50 largest
Mortgage Loans in the Mortgage Pool.)

         (Mortgage Loans having an aggregate Scheduled Principal Balance of
approximately $, representing % of the aggregate Scheduled Principal of the
Mortgage Loans as of the Cut-Off-Date, are Simple Interest Loans.

         (Some of the Mortgage Loans contain" due-on-sale" provisions. Such a
clause permits the lender to accelerate the maturity of the Mortgage Loan if
the Borrower sells, transfers or conveys the Mortgaged Property or the
Borrower's interest in the Mortgaged Property. The Agreement obligates the
Master Servicer or the Special Servicer, as the case may be, to determine, in
accordance with the applicable provisions of the Agreement, whether to enforce
such "due-on-sale" provisions. See "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
- -- Enforceability of Certain Provisions" in the Prospectus.)

         (Some of the Mortgage Loans may also be secured by one or more
assignments of leases and rents, management agreements or operating agreements
relating to the Mortgaged Property and in some cases by certain letters of
credit, personal guarantees or both. See "THE MORTGAGE POOLS -- General" and
"CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS -- Leases and Rents" in the
Prospectus.)

         (Some of the Mortgage Loans also have Notes which may provide the
holder thereof with the right to call such Notes at times specified therein.
The Agreement provides, however, that the Trustee will not exercise its right
to call any such Note unless the Special Servicer directs the Trustee to
exercise such right in connection with a default under such Note.)

         (Many of the Mortgage Loans do not provide either for any lockout
period in which prepayments are prohibited or for any prepayment premium,
penalty or charge in connection with the prepayment thereof, or if such
provisions were included in the Notes they have expired.)

         (In addition, Mortgage Loans having an aggregate Scheduled Principal
Balance of approximately $, representing % of the aggregate Scheduled Principal
Balance of the Mortgage Loans as of the Cut-Off-Date, are "wraparound" mortgage
loans. A "wraparound" mortgage loan is one that is secured by real property on
which there exists a senior mortgage and whose principal balance equals the
aggregate of the principal amount of the loan secured by the senior mortgage
plus the principal amount of the loan funded by the wraparound (or junior)
lender. The Agreement will require the Master Servicer to remit timely the
portion of each related Monthly Payment that is payable to the senior mortgagee
in accordance with the provisions of each such "wraparound" mortgage loan or
otherwise.)

         (A (substantial) portion of the Mortgage Loans are "nonrecourse" loans
or loans for which recourse may be restricted or unenforceable. In the event of
default of any such Mortgage Loan by the Borrower, the Trustee (or the Special
Servicer acting pursuant to the Agreement) may look only to the related
Mortgaged Property (including any assignment of leases thereof) and any other
collateral security (and not to the Borrower's other assets) for satisfaction
of the amounts due on the related Mortgage Loan. See "CERTAIN LEGAL ASPECTS OF
THE MORTGAGE LOANS -- Anti-Deficiency Legislation" in the Prospectus.

         (All of the cash flow from all of the Mortgaged Properties will be
available to pay interest due under each of the Mortgage Loans. In addition,
the Mortgage Loans are cross-defaulted, and therefore the Trustee will be
entitled to accelerate any or all Mortgage Loans upon the occurrence of a
Mortgage Loan Event of Default and will be entitled to exercise its remedies
against any or all of the Mortgaged Properties.)

         (The Mortgage Loan(s) have been newly originated) (by one or more
financial institutions.) (The Depositor has acquired the Mortgage Loans
directly or through one or more affiliates from the originators thereof or
third parties.)

adjustments). (At origination all Mortgage Loans had Loan-to-Value Ratios of %
or less and approximately % of the Mortgage Loans had Loan-to-Value Ratios of

         The Group (1A) and Group ( ) Mortgage Loans bear interest at a per
annum rate which is adjusted periodically to equal the index ("Index") plus or
minus, in most cases, a fixed percentage set forth in the related Note (the
"Margin"), the sum of which may be subject to a rounding convention provided
for in the related Note, subject, however, to certain limitations described

Floor Interest Rates. It is expected that, following the related Servicing
Transfer Date, such Mortgage Loans will be serviced in accordance with their
terms, including their Floor Interest Rates. In the event that enforcement of
the applicable Floor Interest Rate results in a higher Mortgage Interest Rate,
any resulting increase in the Monthly Payment may increase the likelihood of

         A description of certain additional characteristics of the Group (1F)
Mortgage Loans as of the Cut-Off-Date, estimated as of the date of this
Prospectus Supplement, is set forth in Exhibit hereto. GROUP (1A) MORTGAGE
LOANS

         The Group (1A) Mortgage Loans are adjustable rate mortgage loans
("ARMs"). The Mortgage Interest Rate on any such ARM may adjust as the Index on
which it is based adjusts (as is generally the case for Mortgage Loans for
which the Index is a prime rate) or may be fixed until the First Adjustment
Date set forth in the related Note, adjusting on the First Adjustment Date, and
generally at (one month, six month, twelve month, three year or five year)
intervals thereafter (in each case as described in the related Note). The
Mortgage Interest Rate on Group (1A) Mortgage Loans will be adjusted to a rate
equal to an Index plus or minus the Margin set forth in the related Note;
provided, however, that the adjustments of the Mortgage Interest Rates are
subject to rounding (as described in " -- General" above), to maximum rates
("Maximum Rates") and any Floor Interest Rates set forth in the related Note
and, with respect to certain of the Group (1A) Mortgage Loans, to periodic
Mortgage Interest Rate adjustment maximums or floors. of Group (1A) Mortgage
Loans are subject to a Floor Interest Rate of at least % per annum. (The Group
() Mortgage Loans are subject to Floor Interest Rates which are generally less
than % per annum or to no Floor Interest Rate.) The Index set forth in a Note
may be a (constant maturity treasury index, a bond equivalent treasury yield
index, a rate of interest based on a cost of funds index, a rate of interest
based on LIBOR, a rate of interest based on the prime rate quoted by a
financial institution, a rate of interest based on a Federal Home Loan Bank
("FHLB") rate of interest or some other index). The Index applicable to a Note
is set forth therein. The adjustments to the Mortgage Interest Rates for the
Group (1A) Mortgage Loans may occur as the Index changes or may be based on the
Index available a specified number of days prior to the Adjustment Date (a
"Look-Back Period") or on the most recently published Index as of each
Adjustment Date. of the Group (1A) Mortgage Loans are convertible into fixed
rate Mortgage Loans.

         The Group (1A) Mortgage Loans may provide for adjustment of the
Payment Rates on dates that occur on the related Adjustment Dates for the
Mortgage Interest Rates or at some other frequency (each, a "Payment Adjustment
Date"). The Adjustment Date for a given Group (1A) Mortgage Loan in many cases
differs from the Payment Adjustment Date for such Group (1A) Mortgage Loan.
Accordingly, the Payment Rates of such Mortgage Loans may be less than or
greater than the related Mortgage Interest Rates during certain periods,
resulting in Deferred Interest which is added to the unpaid principal balances
of the related Mortgage Loans (if the Payment Rate is less than the Mortgage
Interest Rate) or positive amortization of such Mortgage Loans (if the Payment
Rate is greater than the Mortgage Interest Rate). The Deferred Interest accrued
on any of the Group (1A) Mortgage Loans will be payable on or before the stated
maturity of the Mortgage Loan.

         The Group (1A) Mortgage Loans generally provide for a Monthly Payment
that is recalculated to an amount that would be sufficient to amortize fully
the unpaid principal balance of such Mortgage Loan generally over the remainder
of the original amortization term, at the Mortgage Interest Rate for such
Mortgage Loan in effect on such Payment Adjustment Date. However, increases or
decreases in the Monthly Payment may be limited to an amount specified in the
related Note above or below the Monthly Payment in effect prior to the related
Payment Adjustment Date (a "Group (1A) Payment Adjustment Cap" and a "Group
(1A) Payment Adjustment Floor," respectively). Such Mortgage Loans may provide
that the Group (1A) Payment Adjustment Caps and Group (1A) Payment Adjustment
Floors will not apply every fifth year or at some other time interval, in each
case at which time the Monthly Payment 


                                     S-39
<PAGE>

will be adjusted to an amount sufficient
to amortize fully the outstanding principal balance of the Mortgage Loan at the
then current Mortgage Interest Rate generally over the remainder of the
original amortization term.

         With respect to approximately % of the aggregate Scheduled Principal
Balance as of the Cut-Off-Date of the Group (1A) Mortgage Loans, the maximum
principal balance which is permitted under the Note as a result of negative
amortization ("Maximum Negative Amortization Amount") is not generally
permitted to exceed a specified maximum amount of 125% of the principal amount
of the Mortgage Loan on the date of origination. With respect to approximately
% of the aggregate Scheduled Principal Balance as of the Cut-Off-Date of the
Group (1A) Mortgage Loans, no Maximum Negative Amortization Amount is
specified. With respect to approximately % of the aggregate Scheduled Principal
Balance of the Group (1A) Mortgage Loans as of the Cut-Off-Date, no negative
amortization is permitted. If the Maximum Negative Amortization Amount is
exceeded as a result of Deferred Interest, the Borrower would be required to
make an additional payment with its next Monthly Payment in an amount equal to
the difference between the unpaid principal balance of the Mortgage Loan and
the Maximum Negative Amortization Amount and, for so long as the unpaid
principal balance of the Mortgage Loan is not less than the Maximum Negative
Amortization Amount, the Monthly Payment would be adjusted to an amount that
would be sufficient to amortize fully the unpaid principal balance of the
Mortgage Loan at the then current Mortgage Interest Rate generally over the
remainder of the original amortization term of such Mortgage Loan, without
regard to the applicable Group (1A) Payment Adjustment Cap. Generally, those
Group (1A) Mortgage Loans without negative amortization caps either may not
create Deferred Interest or may fully re-amortize as described above. ( of the
Mortgage Loans in the Mortgage Loan Group (1A) that have a debt service
coverage ratio known to be at or below 1.0, representing approximately % of the
aggregate Scheduled Principal Balance of the Group (1A) Mortgage Loans as of
the Cut-Off-Date, nevertheless meet the representation in the Agreement that,
as of the Closing Date, all Monthly Payments due on or before, 199__ have been
made.) For further information regarding the debt service coverage ratios of
the Mortgage Loans, including information regarding Mortgage Loans as to which
such ratios were not calculated, see Exhibit Y hereto.

         Approximately __% of the Group (1A) Mortgage Loans are secured by
leasehold mortgages. of the Group (1A) Mortgage Loans, representing $ or % of
the aggregate Scheduled Principal Balance of all Mortgage Loans as of the
Cut-Off-Date, will be Specially Serviced Mortgage Loans as of the Closing Date
if no Monthly Payments are received between the Cut-Off-Date and the Closing
Date. of such Mortgage Loans are among the 50 largest Mortgage Loans.

         In addition, of the Group (1A) Mortgage Loans, representing $ or % of
the aggregate Scheduled Principal Balance of all Mortgage Loans as of the
Cut-Off-Date, are Matured Performing Mortgage Loans.

         A description of certain additional characteristics of the Group (1A)
Mortgage Loans as of the Cut-Off-Date, estimated as of the date of this
Prospectus Supplement, is set forth in Exhibit X hereto. The interest rate
adjustment sensitivity of the Group (1A) Mortgage Loans is affected by, among
other things, the particular Indexes of the Mortgage Loans, the frequency of
adjustments and the applicable caps and floors. Exhibit X hereto identifies, by
Scheduled Principal Balance of Group (1A) Mortgage Loans as of the
Cut-Off-Date, (i) the applicable Indexes, (ii) the frequency of Mortgage
Interest Rate adjustments and adjustments of the Monthly Payments and (iii)
information with respect to the different lifetime and periodic Mortgage
Interest Rate and Payment Rate caps and floors, the portion of the Mortgage
Loans having Balloon Payments, and the weighted average maturity of the
Mortgage Loans. (INSERT CHART OF HISTORICAL VALUES AND DETAILED DESCRIPTION OF
ANY PREDOMINANT INDEX) ASSIGNMENT OF MORTGAGE LOANS.

         At the time of issuance of the Certificates, the Depositor will cause
the Mortgage Loans to be assigned to the Trustee, together with all principal
and interest due on or with respect to such Mortgage Loans, other than (i)
principal and interest due on or before the Cut-Off-Date (plus, for Mortgage
Loans which provide for payment of interest in advance of accrual thereof
rather than in arrears, interest due in the month ending on the day preceding
the Cut-Off-Date), (ii) with respect to Simple Interest Loans, interest
received on or prior to the Cut-Off-Date, and (iii) Principal Prepayments (and
principal payments with respect to Simple Interest Loans) received on or prior
to the Cut-Off-Date. The Trustee, concurrently with such assignment, will
execute and deliver Certificates evidencing the beneficial ownership interests
in the Trust Fund to the Depositor in exchange for the Mortgage Loans (and,
within one Business Day after the Closing Date, the Depositor will deposit into
the Collection Account amounts received on or prior to the Closing Date that
are included in the payments assigned to the Trustee). For information

                   IN ORIGINATING THE MORTGAGE LOANS AND ANY
                 APPRAISALS CONDUCTED IN CONNECTION THEREWITH)

         (The Depositor will, as to each Mortgage Loan, deliver to the Trustee:
(i) the Note, endorsed to the order of the Trustee without recourse; (ii) the
Mortgage and an executed assignment thereof in favor of the Trustee or
otherwise as required by the Agreement; (iii) any assumption, modification or
substitution agreements relating to the Mortgage Loan; (iv) a lender's title
insurance policy (or owner's policy in the case of an Installment Contract),
together with its endorsements, or an attorney's opinion of title issued as of
the date of origination of the Mortgage Loan; (v) if the assignment of leases,
rents and profits is separate from the Mortgage, an executed re-assignment of
assignment of leases, rents and profits to the Trustee; and (vi) such other
documents as may be described in the Agreement (such documents collectively,
the "Mortgage Loan File"). Unless otherwise expressly permitted by the
Agreement, all documents included in the Mortgage Loan File are to be original
executed documents; provided, however, that in instances where the original
recorded Mortgage, Mortgage assignment or any document necessary to assign the
Depositor's interest in Installment Contracts to the Trustee, as described in
the Agreement, has been retained by the applicable jurisdiction or has not yet
been returned from recordation, the Depositor may deliver a photocopy thereof
certified to be the true and complete copy of the original thereof submitted
for recording.) REPRESENTATIONS AND WARRANTIES

         In the Agreement, the seller of the Mortgage Loans to the Depositor or
its affiliate (the "Seller") will give the representations and warranties
described in the Prospectus under "THE MORTGAGE POOLS -- Representations and
Warranties." For information regarding the remedies available to the
Certificateholders and the Trustee for a breach of any such representations and
warranties, see "THE MORTGAGE POOLS -- Representations and Warranties" in the
Prospectus. (The Agreement will also contain certain corporate representations
and warranties of the (Depositor) (Master Servicer).)

         The proceeds of any repurchase or indemnification in respect of a
Mortgage Loan as to which such a breach has occurred will be deposited, subject
to certain limitations set forth in the related Agreement, into the Collection
Account. (The obligations described above and in the Prospectus constitute the
sole remedies available to the Certificateholders or the Trustee for any such
breach of representations and warranties.) See "THE MORTGAGE POOLS --
Representations and Warranties" in the Prospectus. ENHANCEMENT (RESERVE FUND)

         (If required by the Rating Agencies rating the Certificates, on or
prior to the Closing Date the Depositor will deposit in a Reserve Fund cash,
securities or an irrevocable letter of credit in an amount (the "Initial
Deposit") satisfactory to such Rating Agencies and will maintain in such
Reserve Fund an amount equal to $ which amount will be available on any
Distribution Date (for application to the principal of or interest on the
Certificates to the extent funds are not otherwise available therefor in the
Collection Account) (for purposes of providing liquidity) (to cover Basis Risk
Shortfalls) (and for such other purposes as are set forth herein).)

         (The Depositor will have the right on any Distribution Date to cause
the Trustee to withdraw moneys from the Reserve Fund to the extent the balance
in the Reserve Fund exceeds the amount required to be maintained therein.)

         The Reserve Fund will (not) be a part of the Trust Fund or the REMIC
Pool. (The pledge of the Reserve Fund will be made pursuant to the terms of the
Collateral Security Agreement.) The (Collateral Security) Agreement will
provide that the Initial Deposit (unless permitted to be distributed to the
Depositor as described below) may be invested, at the direction of the
Depositor, in Permitted Investments. (Any earnings resulting from the
investment of amounts held in the Reserve Fund will be remitted to the
Depositor.)

         (Notwithstanding the foregoing, if the amount on deposit in the
Reserve Fund, after giving effect to transfers into the Reserve Fund on such
date, is less than $ , which amount is equal to % of the aggregate Scheduled
Principal Balance of the Mortgage Loans as of the Cut-Off-Date (the "Liquidity
Amount"), such amount will be available, so long as any Class Certificates are
outstanding, only to ensure (i) payments of interest due on the Class
Certificates and (ii) distributions of Optimal Mortgage Loan Principal then
payable or past due on the Class Certificates, and any 


                                     S-41
<PAGE>

amounts otherwise payable with respect to the Class , Class () or Class R 
Certificates will be used to the extent necessary to restore the amount on 
deposit in the Reserve Fund to the Liquidity Amount.)

         The Initial Deposit will be held in the Reserve Fund in accordance
with the terms of the Collateral Security Agreement. The Depositor will have no
obligation to deposit in the Reserve Fund any amounts in respect of any
distributions it may have received or to make any other deposits subsequent to
the Initial Deposit, regardless of whether amounts in the Reserve Fund are
sufficient to ensure payment of principal and interest on the Classes of
Regular Certificates. The conditions for the release of amounts in the Reserve
Fund to the Depositor will be set forth in the Collateral Security Agreement
and shall be in accordance with the requirements established by the Rating
Agencies for the maintenance of the initial ratings of the Regular
Certificates.

         The Collateral Security Agreement will require that the Depositor
grant to the Collateral Agent a security interest in the Reserve Fund. The
Collateral Security Agreement will provide that, with the approval of the
Rating Agencies, at the option of the Depositor, the Reserve Fund can be
replaced, in whole or in part, with a form of credit enhancement that is, or is
invested in, securities or obligations which are backed by the full faith and
credit of the United States of America, provided that such replacement does not
result in the withdrawal or downgrade of the then current rating or ratings of
the Regular Certificates by the Rating Agencies.

         The Collateral Security Agreement will provide that the assets held in
the Reserve Fund can be sold by the Depositor to third parties, subject to the
lien in favor of the Collateral Agent, on the condition that such transfer be
approved by the Rating Agencies consistent with the maintenance of the initial
ratings on the Regular Certificates.

         The institution serving as Trustee will also serve as Collateral Agent
under the Collateral Security Agreement.) SUBORDINATION OF THE CLASS ___
CERTIFICATES.

         Distributions of interest and principal with respect to the Class
Certificates will be subordinate to distributions of interest and principal
with respect to the Class () Certificates to the extent that (i) no
distribution of interest or principal is permitted to be made with respect to
the Class Certificates on any Distribution Date until interest and principal
then payable to the Class () Certificates have been paid and the aggregate
Certificate Principal Amount of the Class () Certificates has been reduced at
least to an amount equal to the aggregate Scheduled Principal Balance of the
Mortgage Loans out of the aggregate Available Distribution Amounts (including
any funds available therefor in the Reserve Fund) to the extent described above
under " -- Distributions --Allocation Among Classes" and (ii) so long as any of
the Class () Certificates remain outstanding, no distribution of interest or
principal is permitted to be made with respect to the Class or Class ()
Certificates on any Distribution Date for so long as the amount on deposit in
the Reserve Fund (after giving effect to any withdrawal therefrom on such
Distribution Date) is equal to or less than the Liquidity Amount, to the effect
that any funds then available in the Reserve Fund are preserved for the Holders
of the Class () Certificates or servicing advances, and any amounts otherwise
available for distribution to the Holders of the Class () or Class ()
Certificates are deposited into the Reserve Fund to the extent needed to
restore it to the Liquidity Amount.

         (All amounts with respect to the Group () Mortgage Loans which are
available for distributions will be allocated first to interest and principal
then distributable with respect to the Class () Certificates and only
thereafter will be available for application to amounts then distributable with
respect to the Class () and Class () Certificates. Principal distributable on
the Class () Certificates generally will include all principal received, due
(other than Balloon Payments) but not received, or deemed to be due, on the
Group () Mortgage Loans. No amounts with respect to the Group () Mortgage Loans
will be available to make distributions on the Class () Certificates (except
with respect to amounts deposited in the Reserve Fund in respect of Eligible
Multifamily Mortgage Loans). As a result, the Class () or Class () Certificates
could be entitled to distributions from payments received with respect to Group
() Mortgage Loans at times when payments on the Group () Mortgage Loans are
insufficient to pay in full amounts currently payable on the Class ()
Certificates. This result could only occur, however, in the remote
circumstances where on any Distribution Date the cumulative amount of Reserve
Fund draws (net of reimbursed advances) exceeds the sum of the Initial Deposit
and the cumulative amount of Reserve Fund deposits (other than reimbursements
of advances) from cash flows on Eligible Multifamily Mortgage Loans. Even in
the absence of shortfalls in payments on the Group () Mortgage Loans, if the
rate of principal payments of the Group () Mortgage Loans is sufficiently
faster than the rate of principal payments on the Group () Mortgage Loans, the
Class () or Class () Certificates could be entitled to distributions of Optimal
Mortgage Loan Principal for Mortgage Loan Group () at times when the Class ()
Certificates are still outstanding.) (OTHER CREDIT ENHANCEMENT)

              (INFORMATION TO BE PROVIDED BY THE MASTER SERVICER.)

         The information set forth in the preceding paragraphs concerning the
Master Servicer has been provided by it. Accordingly, the Seller makes no
representation as to the accuracy or completeness of such information.

         The Master Servicer will be responsible for servicing the Mortgage
Loans pursuant to the Agreement. (With respect to any Mortgage Loan that
becomes a Specially Serviced Mortgage Loan, the Master Servicer will transfer
servicing responsibilities with respect to such Mortgage Loan to the Special
Servicer, as discussed under "SERVICING OF THE MORTGAGE LOAN -- General" in the
Prospectus. Mortgage Loans having an aggregate Scheduled Principal Balance as
of the Cut-Off-Date of approximately $ , representing % of the aggregate
Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off-Date, will
be transferred to the Special Servicer on the Closing Date, if no Monthly
Payments are received on such Mortgage Loans from the Cut-Off-Date to the
Closing Date, because they will then have payments more than 60 days past due.)
(In addition, included in the Mortgage Pool are Matured Performing Mortgage
Loans having an aggregate Scheduled Principal Balance of approximately $
representing % of the aggregate Scheduled Principal Balance of the Mortgage
Loans as of the Cut-Off-Date, which will be transferred to the Special Servicer
on the Closing Date.)

         (CHARTS TO BE INSERTED SUMMARIZING THE MASTER
         SERVICER'S FORECLOSURE AND DELINQUENCY EXPERIENCE
         IN RESPECT OF LOANS OF THE SAME TYPE AS THE MORTGAGE LOANS)

         While the above foreclosure and delinquency experience is typical of
the Master Servicer's recent experience, there can be no assurance that
experience on the Mortgage Loans will be similar. The information should not be
considered to reflect the credit quality of the Mortgage Loans in the Mortgage
Pool or as a basis for assessing the likelihood, amount or severity of losses
on the Mortgage Pool. The statistical data in the table is based on all of the
loans in the Master Servicer's servicing portfolio. The Mortgage Loans may be
more recently originated than, and are likely to have other characteristics
which distinguish them from, the majority of the loans in the Master Servicer's
servicing portfolio.

             (INFORMATION TO BE PROVIDED BY THE SPECIAL SERVICER.)

         The information set forth in the preceding paragraphs concerning the
Special Servicer has been provided by it. Accordingly, the Depositor makes no
representation as to the accuracy or completeness of such information.

COLLECTION AND OTHER SERVICING PROCEDURES

         The Master Servicer (or the Special Servicer, with respect to
Specially Serviced Mortgage Loans) will make reasonable efforts to collect all
payments called for under the Mortgage Loans and will, consistent with the
Agreement, follow such collection procedures as it deems necessary or
desirable. Under the Agreement, the Master Servicer will 


                                     S-43
<PAGE>

establish and maintain the Collection Account and the Escrow Account, and the
Special Servicer will establish and maintain the REO Account. For information
regarding the maintenance of these accounts and the obligations of the Master
Servicer and Special Servicer under the respective accounts, see "DESCRIPTION
OF THE CERTIFICATES -- Accounts" and "SERVICING OF THE MORTGAGE LOANS --
Collections and Other Servicing Procedures" in the Prospectus.

INSURANCE

         The Agreement provides that the Master Servicer maintain or require
each Borrower to maintain insurance in accordance with the related Mortgage,
which generally will include a standard fire and hazard insurance policy with
extended coverage, and, in some cases, flood insurance. Likewise, the Special
Servicer will cause to be maintained fire and hazard insurance with extended
coverage on each REO Property and, in some cases, flood insurance. For further
information regarding the maintenance and coverage of insurance policies as
described above, see "SERVICING OF THE MORTGAGE LOANS -- Insurance" in the
Prospectus.

         In addition, to the extent required by the related Mortgage, the
Master Servicer may require the Borrower to maintain other forms of insurance
including, but not limited to, loss of rents endorsements, business
interruption insurance and comprehensive public liability insurance, and the
Agreement may require the Special Servicer to maintain public liability
insurance with respect to any REO Properties. See "SERVICING OF THE MORTGAGE
LOANS -- Insurance" in the Prospectus.

         POLICY, BANKRUPTCY BOND, REPURCHASE BOND,
         CERTIFICATE GUARANTEE INSURANCE TO BE DESCRIBED,
         IF APPLICABLE)

SERVICING COMPENSATION AND PAYMENT OF EXPENSES

         The Master Servicer's principal compensation for its activities under
the Agreement will come from the payment to it or retention by it, with respect
to each Mortgage Loan, of the Servicing Fee (as defined below).

         The "Servicing Fee," including the Reserved Amount (as defined below),
with respect to each Mortgage Loan and for any Due Period, is an amount equal
to thirty days' interest (or, in the event of any payment of interest which
accompanies a Principal Prepayment made by the Borrower, interest for such
number of days from the preceding Due Date to the date of such Principal
Prepayment), calculated on the basis of a 360-day year consisting of twelve
30-day months, at the Servicing Fee Rate on the Scheduled Principal Balance of
such Mortgage Loan immediately prior to the application of the principal
portion of the Monthly Payment due on the Due Date in such Due Period. The
Servicing Fee Rate, with respect to each Mortgage Loan other than a Specially
Serviced Mortgage Loan, is a rate equal to % per annum and, with respect to
each Specially Serviced Mortgage Loan, is a rate equal to % per annum. A
portion of the Servicing Fee includes % per annum of the then unpaid principal
balance of each of the Mortgage Loans (the "Reserved Amount") which the Master
Servicer will use to pay certain ongoing expenses associated with the Mortgage
Loans and incurred by it in connection with its responsibilities under the
Agreement, including the annual fees of the Trustee and the Collateral Agent,
the Basic Fee (as defined below) of the Special Servicer, ongoing fees payable
to the Rating Agencies and certain other expenses of the Trust Fund. The Master
Servicer will be entitled to reimbursement from the Collection Account and, if
necessary, from the Reserve Fund for the amount by which such expenses exceed
the Reserved Amount.

         In addition, the Master Servicer will be entitled to receive, as
additional compensation, Prepayment Premiums, late fees and certain other fees
collected from any Borrower other than with respect to Specially Serviced
Mortgage Loans, and any interest or other income earned on funds deposited in
the Collection Account, the Distribution Account and, except to the extent such
income is required to be paid to the related Borrowers, the Escrow Account.

         (The Special Servicer's principal compensation for its activities
under the Agreement will come from payment to it or retention by it, with
respect to each Mortgage Loan, of the Special Servicer Fee. The Special
Servicer Fee will include ((x) a fee (the "Basic Fee") calculated at a rate
equal to ___% per annum with respect to each Mortgage Loan on the Scheduled
Principal Balance of such Mortgage Loan, payable from the Collection Account,
(y) an additional fee 


                                     S-44
<PAGE>

(the "Supplemental Fee") equal to the excess, if any, of (i) an amount
calculated at a rate equal to % applied solely to the Specially Serviced
Mortgage Loans over (ii) the Basic Fee, which Supplemental Fee shall be payable
from the Reserve Fund, to the extent of funds available therein, and (z) a fee
(the "Workout Fee") equal to a fixed percentage (the "Workout Fee Rate"),
varying from ___% to ___% per annum, depending on the unpaid principal balance
of each Mortgage Loan as to which it is acting or at any time acted as servicer
(including those for which servicing has been returned to the Master Servicer),
of net collections and net proceeds received with respect to each such Mortgage
Loan) (other formula to compensate any Special Servicer).

         Notwithstanding the foregoing, the fixed percentage with respect to
any net Liquidation Proceeds received in connection with a sale of REO Property
or upon a Final Recovery Determination for any Mortgage Loan will equal the
product of (a) the otherwise applicable fixed percentage referred to in the
preceding paragraph and (b) a fraction the numerator of which is equal to the
net Liquidation Proceeds received (after payment of all other fees and
reimbursement of all advances and expenses with respect thereto) and the
denominator of which is equal to the unpaid principal balance of the related
Mortgage Loan and accrued and unpaid interest thereon. The Master Servicer and
Special Servicer will each be entitled to receive its accrued unpaid servicing
fees out of net Liquidation Proceeds prior to application of such proceeds to
reduce unpaid principal and interest on the related Mortgage Loan.

         The Special Servicer will remit payments with respect to any
modification fees payable by Borrowers in accordance with the Special
Servicer's customary servicing practices and late fees, Prepayment Premiums and
certain other fees collected from any Borrower for Specially Serviced Mortgage
Loans to the Master Servicer for deposit in the Collection Account.)

ADVANCES

         (Neither) (T)he Master Servicer (nor the Special Servicer) will be
obligated to make advances with respect to delinquent Monthly Payments or
Balloon Payments on Mortgage Loans (or for such other purposes as are set forth
in the Agreement); (instead, advances with respect to delinquent Monthly
Payments (and in the case of Simple Interest Loans, delinquent payments of
interest only), Assumed Scheduled Payments (in the case of delinquent Balloon
Mortgage Loans) and Assumed Monthly Payments (in the case of Discounted
Mortgage Loans) will be made in the form of withdrawals from the Reserve Fund.)
Taxes, insurance premiums and Property Protection Expenses will be payable from
amounts on deposit in the Collection Account or, to the extent such amounts are
insufficient, from the Reserve Fund. In the event that amounts in the Reserve
Fund are depleted, (i) neither the Master Servicer nor the Special Servicer
will be obligated to make advances with respect to delinquent or defaulted
Mortgage Loans and (ii) taxes, insurance premiums and Property Protection
Expenses will be paid from advances by the Master Servicer or the Special
Servicer (in each case required with respect to Mortgage Loans serviced by it)
to the extent that such advances are, in the judgment of the Master Servicer or
Special Servicer, as applicable, reasonably recoverable from future payments
and collections on the related Mortgage Loans, out of Insurance Proceeds,
Liquidation Proceeds or otherwise. The Master Servicer and the Special Servicer
will be entitled to be reimbursed for any such advances, plus interest thereon,
from amounts on deposit in the Collection Account, as provided in the
Agreement.)

         (The (Master) Servicer will advance its own funds (or funds equal to
the aggregate amount of payments of principal and interest) (adjusted to the
Net Mortgage Interest Rate) which were due on the Due Date and which were
delinquent as of the close of business on the business day preceding the
Remittance Date, (up to an aggregate amount equal to % of the aggregate
outstanding principal balance of the Mortgage Loans, less previously
unreimbursed advances) (subject to such advances being recoverable, in the
reasonable judgment of the Master Servicer, under any Insurance Policy,
Liquidation Proceeds or otherwise from the Mortgagor). The (Master) Servicer
will also be obligated to make advances in respect of certain taxes and
insurance premiums not paid by Mortgagors on a timely basis. (Advances are
reimbursable from recoveries without interest.) Such right of reimbursement
from such recoveries is prior to the right of (Certificateholders).)

         (Various Servicers approved by the Master Servicer will provide
customary servicing functions with respect to the Mortgage Loans pursuant to
Servicing Agreements between them and the Depositor. (Among other things, the
Servicers are obligated under certain circumstances to make advances with
respect to the Mortgage Loans and to purchase any Mortgage Loans for which
mortgage insurance is denied on the grounds of fraud or misrepresentation.) See
"SERVICING OF THE MORTGAGE LOANS" herein.) (Description of any sub-servicing
arrangements with any other parties, including the obligations thereof, to be
described)

<PAGE>

         (Depositor will enter into a Master Servicing Agreement with respect
to the Mortgage Loans. The Master Servicer will supervise all servicing of the
Mortgage Loans and assume the obligations of any Servicer that is terminated
for cause by the Trustee unless another substitute Servicer is appointed. The
obligation of the Master Servicer to purchase Mortgage Loans that a Servicer
has failed to purchase when required to do so under the Servicing Agreement
will be limited. See "SERVICING OF THE MORTGAGE LOANS" herein.)

(SENIOR LIEN ADVANCES

         Neither the Master Servicer nor the Special Servicer will make Senior
Lien Advances in respect of the Mortgage Loans from its own funds. However,
subject to the following paragraph, in accordance with the servicing standard
specified in the Agreement, the Special Servicer will cause the Trustee to
apply funds from the Reserve Fund to make Senior Lien Advances with respect to
delinquent payments of principal and interest (or other charges) on mortgage
loans senior to the Mortgage Loans that have not been previously advanced, or
to satisfy in full such senior liens, to the extent the Special Servicer
determines that to do so would result in an increase in the amount of
Liquidation Proceeds ultimately distributable to the Certificateholders.
Amounts recovered as Liquidation Proceeds with respect to the related Mortgage
Loans will be reimbursed to the Reserve Fund.)

                     MODIFICATIONS, WAIVERS AND AMENDMENTS

         Each of the Master Servicer and the Special Servicer is entitled,
subject to certain conditions set forth therein, to modify, waive or amend the
terms of any Mortgage Loan without the consent of the Trustee or any
Certificateholder, as described under "SERVICING OF THE MORTGAGE LOANS --
Modifications, Waivers and Amendments" in the Prospectus. In particular, the
Special Servicer will use its best efforts to modify (i) a Group () Mortgage
Loan to provide for calculation of interest at a fixed rate and (ii) a Group ()
Mortgage Loan to provide for calculation of interest at a rate based upon
(LIBOR) (COFI).

         The Special Servicer may, with respect to any Specially Serviced
Mortgage Loan, subject to the terms and conditions set forth in the Agreement,
some of which are described below, modify, waive or amend the terms of such
Mortgage Loans if the Special Servicer determines that a material default has
occurred or a payment default has occurred or is reasonably foreseeable. The
Special Servicer may extend the maturity date of such Mortgage Loan to a date
(the "Optimal Wind-Down Date") not later than the earlier of (i) two years
prior to the Final Scheduled Distribution Date or (ii) if such Mortgage Loan is
secured by a Mortgage on a leasehold estate, the date occurring ten years prior
to the termination of such leasehold estate. Interest on any extended Mortgage
Loan will be calculated on the basis of a 360-day year consisting of twelve
30-day months. To the extent that the net operating income of the related
Mortgaged Property (together with such other sources of payment as the Special
Servicer determines are acceptable therefor) is sufficient to support Monthly
Payments which will amortize the Mortgage Loan on a level payment basis to the
rescheduled maturity date, the Special Servicer will require that Monthly
Payments be made in such amounts. If the Special Service determines that net
operating income will not be so sufficient, the Special Servicer will either
agree to a schedule of Monthly Payments that would fully amortize the Mortgage
Loan by the Optimal Wind-Down Date after providing for a Balloon Payment at the
rescheduled maturity date or reduce the Monthly Payments on any Specially
Serviced Mortgage Loan to a level that can be supported by net operating income
(either by reducing the Mortgage Interest Rate or the Payment Rate thereof,
reducing the principal payment component of the Monthly Payments or a
combination thereof). Any Mortgage Loan which has been modified as described
and which has become a Discounted Mortgage Loan under the Agreement will result
in a draw from the Reserve Fund if funds therein are available therefor and an
additional distribution in reduction of the Certificate Principal Amount of the
applicable Class or Classes of Offered Certificates. See "DESCRIPTION OF THE
CERTIFICATES -- Distributions."

         (Except for extensions of maturity dates of Matured Performing
Mortgage Loans,) the Special Servicer will not agree to any modification,
waiver or amendment of the payment terms of a Mortgage Loan unless the Special
Servicer has determined that such modification, waiver or amendment is
reasonably likely to produce a greater recovery on a present value basis than
liquidation of the Mortgage Loan. Prior to agreeing to any such modification,
waiver or amendment, the Special Servicer will give notice thereof to the owner
of the Reserve Fund who will have the right to veto such decision of the
Special Servicer. EVIDENCE OF COMPLIANCE

<PAGE>

         Under the Agreement, each of the Master Servicer and the Special
Servicer is required to provide a statement of compliance with the Agreement,
as more fully described under "SERVICING OF THE MORTGAGE LOANS -- Evidence of
Compliance" in the Prospectus.

             YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS GENERAL

         The yield to maturity on any Class of Regular Certificates will depend
upon the price paid by the Certificateholder, the related Pass-Through Rate and
the rate and timing of the repayment of principal in respect of such Regular
Certificates. The yield to maturity on the (Class ) Certificates (Floating Rate
Certificates) will be affected, in particular, by the levels of (LIBOR) (COFI).
The rate and timing of the repayment of principal of the Offered Certificates
will be affected both by (x) the rate of principal payments (particularly
Balloon Payments) on the related Mortgage Loans including, for this purpose,
unscheduled payments such as prepayments by Borrowers and prepayments resulting
from modifications, defaults, repurchases due to certain breaches of
representations and warranties and (y) the amount of interest payments on the
Mortgage Loans which is available for distribution of principal on the Regular
Certificates.

         All of the Group (1F) Mortgage Loans bear interest at fixed rates.
(All) of the Group (1A) and Group () Mortgage Loans are ARMs, the Mortgage
interest Rates of which are determined by reference to various Indexes. The
Seller is not aware of any relevant publicly available statistics that set
forth principal prepayment experience or prepayment forecasts of commercial
(and multifamily residential) mortgage loans over an extended period of time,
especially with respect to commercial (and multifamily residential) ARMs. The
rate of principal prepayments with respect to mortgage loans generally has
fluctuated in recent years. As is the case with fixed rate mortgage loans, ARMs
may be subject to a greater rate of principal prepayments in a declining
interest rate environment, particularly ARMs with minimum interest rate
provisions.

         The rate of principal payments on the Offered Certificates will be
affected by the rate of principal payments (including prepayments) on the
related Mortgage Loans. Generally, prepayments on the Mortgage Loans (including
prepayments resulting from defaults) will tend to shorten the weighted average
lives of the Class () Certificates whereas delays in liquidations of defaulted
Mortgage Loans and modifications extending the maturity of Mortgage Loans will
tend to lengthen the weighted average lives of the Class () Certificates. Such
prepayments may affect the Class () and Class () Certificates differently as
described below. Any changes in weighted average lives may adversely affect the
yield to Certificateholders. Prepayments resulting in a shortening of such
weighted average lives may be made at a time of low interest rates when Holders
may be unable to reinvest such prepayments at Pass-Through Rates payable on the
Offered Certificates, while delays and extensions resulting in lengthening of
such weighted average lives may occur at a time of high interest rates when
Holders may have been able to reinvest payments received by them at higher
rates.

         Principal prepayments may be influenced by a variety of economic,
geographic, demographic, social, tax, legal and other factors. In general, if
prevailing interest rates fall significantly below the interest rates on the
Mortgage Loans (and in particular Mortgage Loans with fixed Mortgage Interest
Rates or with minimum adjustable Mortgage Interest Rates that are higher than
prevailing interest rates), the Mortgage Loans are likely to be subject to
higher prepayments than if prevailing rates remain at or above the interest
rates on such Mortgage Loans. Conversely, if prevailing interest rates rise
significantly above the Mortgage Interest Rates on the Mortgage Loans, the rate
of prepayment would be expected to decrease. Other factors affecting prepayment
of the Mortgage Loans include the availability of credit for mortgage
refinancing, changes in tax laws (including depreciation benefits), changes in
Borrowers' net equity in the Mortgaged Properties, servicing decisions,
prevailing general economic conditions and the relative economic vitality of
the areas in which the Mortgaged Properties are located, the terms of the
Mortgage Loans (for example, the existence of due-on-sale and
due-on-encumbrance clauses), the quality of management of the Mortgaged
Properties and the availability of other opportunities for investment. (A
significant number) of the Mortgage Loans may be prepaid at any time without
penalty, or provide for small prepayment premiums or penalties which are not
expected to be an effective deterrent to prepayment. (Some) of the Mortgage
Loans, however, continue to have prepayment premiums or penalties which could
be a deterrent to prepayments. The Depositor makes no representation as to the
particular factors that will affect the rate of prepayment of the Mortgage
Loans, the relative importance of any such factors, the percentage of the
principal balance of the Mortgage Loans that will be paid as of any date or the
overall rate of prepayments on the Mortgage Loans. See "THE TRUST FUND" herein.
Because the Mortgage Loans are subject to prepayment, and because (certain) of
the Mortgage Loans will have remaining terms to stated maturity that are
shorter than those assumed in calculating the Final Scheduled Distribution Date
of the Certificates, the 


                                     S-47
<PAGE>

Certificate Principal Amount of one or more Classes of the Certificates may be
reduced to zero prior to their Final Scheduled Distribution Date. In addition,
delinquencies could result in distributions after the Final Scheduled
Distribution Date of one or more Classes of Certificates. As a result, the
Certificate Principal Amount of each Class of Certificates may be reduced to
zero significantly earlier or later than its respective Final Scheduled
Distribution Date.

         The effective yield to Holders of the Fixed Rate (and Class ())
Certificates will differ from the yield otherwise produced by the applicable
Pass-Through Rate and purchase prices of such Certificates because principal
and interest distributions will not be payable to such Holders until at least
the 25th day of the month following the month of accrual (without any
additional distribution of interest or earnings thereon in respect of such
delay).

         If the purchaser of an Offered Certificate purchased at a discount
from its initial Certificate Principal Amount calculates its anticipated yield
to maturity based on an assumed rate of payment of principal that is faster
than that actually experienced on such Certificate, the actual yield to
maturity will be lower than that so calculated. Conversely, if the purchaser of
an Offered Certificate purchased at a premium calculates its anticipated yield
to maturity based on an assumed rate of payment of principal that is slower
than that actually experienced on such Certificate, the actual yield to
maturity will be lower than that so calculated.

         The timing of changes in the rate of prepayments on the related
Mortgage Loans may significantly affect an investor's actual yield to maturity,
even if the average rate of principal payments is consistent with an investor's
expectation. In general, the earlier a prepayment of principal of the related
Mortgage Loans, the greater the effect on an investor's yield to maturity. The
effect on an investor's yield of principal payments occurring at a rate higher
(or lower) than the rate anticipated by the investor during the period
immediately following the issuance of the Offered Certificates may not be
offset by a subsequent like decrease (or increase) in the rate of principal
payments. An investor must make an independent decision as to the appropriate
prepayment scenario to be used in deciding whether to purchase the Offered
Certificates.

         Investors should consider the risk that rapid rates of prepayments on
the related Mortgage Loans, and therefore of principal payments on the Offered
Certificates, may coincide with periods of low prevailing interest rates.
During such periods, the effective interest rates on securities in which an
investor may choose to reinvest amounts received as principal payments on such
investor's Offered Certificate may be lower than the applicable Pass-Through
Rate. Conversely, slow rates of prepayments on the Mortgage Loans, and
therefore of principal payments on the various Classes of Offered Certificates,
may coincide with periods of high prevailing interest rates. During such
periods, the amount of principal payments available to an investor for
reinvestment at such high prevailing interest rates may be relatively low.

         Realized Losses will not be allocated to the holders of the Class
Certificates until the date on which the amount of principal payments on the
Mortgage Loans to which the holders of the Class and Class Certificates are
entitled has been reduced to zero as a result of the allocation of losses to
the Class and Class Certificates. Prior to such time, such Realized Losses will
be allocated first to the Class Certificates until the Certificate Principal
Amount of the Class Certificates has been reduced to zero, and then to the
Class Certificates until the Certificate Principal Amount of the Class
Certificates has been reduced to zero. The yield to maturity on the Class
Certificates, which are subordinated, will therefore be more sensitive than the
Class Certificates to losses due to defaults on the Mortgage Loans (and the
timing thereof), because the entire amount of such losses will be allocable to
the Class Certificates prior to the Class Certificates. To the extent not
covered by the Advances by the (Master) Servicer, delinquencies on Mortgage
Loans may also have a relatively greater effect on the yield to investors in
the Class Certificates. Amounts otherwise distributable to holders of the Class
Certificates will be made available to protect the holders of the Class
Certificates against interruptions in distributions due to certain mortgagor
delinquencies. Such delinquencies, even if subsequently cured, may affect the
timing of the receipt of distributions by the holders of Class Certificates,
because the entire amount of those delinquencies would be borne by the Class
Certificates prior to the Class Certificates.

                        SPECIAL YIELD CONSIDERATIONS OF
                     THE CLASS __ AND CLASS __ CERTIFICATES

         Because the Class ___ Certificates are entitled to distributions of
interest only, the yield to maturity on such Classes will be extremely
sensitive to the rate of principal prepayments on the Mortgage Loans, which may
fluctuate 


                                     S-48
<PAGE>

significantly from time to time. In addition, the amount of interest payable on
the Class Certificates will decrease more








































                                     S-49
<PAGE>



significantly as a result of principal prepayments on Mortgage Loans with
relatively high Net Mortgage Interest Rates. In general, Mortgage Loans with
relatively high Net Mortgage Interest Rates will prepay faster than Mortgage
Loans with relatively low Net Mortgage Interest Rates. Investors should fully
consider the associated risks including the risk that a rapid rate of principal
prepayments could result in the failure of investors in Class Certificates to
recoup their initial investment.

         The offering price of the Class Certificates, which are entitled to
payments of principal only, is expected to include a substantial discount from
the original Certificate Principal Amount. As a result, any projection of the
yield to maturity of the Class Certificates made by an investor must include an
assumption as to the anticipated rate of prepayments on the Class Mortgage
Loans and as to the resulting weighted average life of the Class Certificates.
If the weighted average life of the Class Certificates is longer than that
assumed by an investor in calculating an anticipated yield to maturity, the
yield to maturity actually realized by such investor will be less, and may be
substantially less, than the anticipated yield.

         The Class Certificates represent in the aggregate the right to receive
distributions allocable to principal based on the Class Fraction of certain
Mortgage Loans (each, a "Class Mortgage Loan"). Generally, prepayments on the
Class Mortgage Loans will have a positive effect on the yield to maturity of
the Class Certificates; however, a low rate of principal prepayments on the
Class Mortgage Loans, or disproportionately lower principal payments on Class
Mortgage Loans having relatively large Class Fractions (i.e., relatively low
Net Mortgage Interest Rates), will adversely affect the yield on the Class
Certificates.

         To illustrate the significance of the effect of prepayments on
aggregate distributions on the Class and Class Certificates, the following
table shows the Pre-tax Yield to Maturity of the Class and Class Certificates
held to maturity, at various percentages of the CPR model:

         WEIGHTED AVERAGE LIFE OF THE REGULAR CERTIFICATES

         Weighted average life refers to the average amount of time from the
date of issuance of a security until each dollar of principal of such security
will be repaid to the investor. The weighted average lives of the Regular
Certificates will be influenced by the rate at which principal payments
(including scheduled payments, principal prepayments and payments made pursuant
to any applicable policies of insurance) on the Mortgage Loans are made.
Principal payments on Mortgage Loans may be in the form of scheduled
amortization or prepayments (for this purpose, the term "prepayment" includes
prepayments by Borrowers and prepayments resulting from modifications,
defaults, repurchase due to certain breaches of representations and warranties
or other disposition of the Mortgage Loans). Since all principal payments on
the Mortgage Loans are initially directed to reduce the (respective)
Certificate Principal Amount(s) of the Class () Certificates, prepayments on
the Mortgage Loans will have a disproportionately greater tendency to shorten
the weighted average lives of the Class () Certificates than the weighted
average lives of the Class () and Class () Certificates.

         In contrast, (a substantial portion) of the excess of interest due on
the Mortgage Loans, net of servicing compensation, over interest due on the
Regular Certificates will generally be applied to the Class () Certificates as
described herein under "DESCRIPTION OF THE CERTIFICATES -- Distributions - --
Allocation Among Classes." Accordingly, while the amount of such excess
interest will generally be affected primarily by changes in interest rates and
the interest rate adjustment terms of the Mortgage Loans, and accordingly by
the spread between (LIBOR) and the current Mortgage Interest Rate, as described
under "DESCRIPTION OF THE CERTIFICATES -- Distributions -- Basis Risk" herein,
any payment experience which would reduce such excess interest, including
prepayments (Mortgage Loans having higher interest rates being expected to
prepay first) and Prepayment Interest Shortfalls, will have a tendency to
extend the weighted average life of the Class () Certificates although such
tendency may be offset to some extent by the application of principal
prepayments to such Classes of Certificates. The level of such excess interest
will also be affected by other factors described under "DESCRIPTION OF THE
CERTIFICATES -- Distributions -- Basis Risk" herein. The weighted average life
of each such Class will also be influenced by delays associated with realizing
on defaulted Mortgage Loans, and by extensions given in connection with
modifications of Mortgage Loans. Since a (significant number) of Mortgage Loans
have Balloon Payments due at maturity, and because the ability of the Borrower
to make a Balloon Payment typically will depend upon its ability either to
refinance the loan or to sell the related Mortgaged Property, there is a risk
that a number of Mortgage Loans having Balloon Payments may default at
maturity, or that the Special Servicer may extend the maturity of such a
Mortgage Loan in connection with a workout. In the case of defaults, recovery
of proceeds may be delayed by, among other things, bankruptcy of the Borrower
or adverse conditions in the market where the property is located. In order to
minimize losses on Specially 


                                     S-51
<PAGE>

Serviced Mortgage Loans, the Special Servicer is given considerable flexibility
under the Agreement to modify Mortgage Loans which are in default or as to
which default is reasonably foreseeable. Certificateholders are not entitled to
receive distributions of Balloon Payments when due except to the extent they
are actually received (and instead are entitled only to receive certain Assumed
Scheduled Payments until final liquidation, and the remaining balance upon such
final liquidation). Consequently, any defaulted Balloon Payment or modification
which extends the maturity of a Mortgage Loan will tend to extend the weighted
average lives of the Class () Certificates and to a lesser extent, the weighted
average of other Classes of Regular Certificates. See "SERVICING OF THE
MORTGAGE LOANS - -- Modifications, Waivers and Amendments" herein and in the
Prospectus

         In contrast, because the Class () Certificates are being offered at a
discount, and because the Class () Certificates are being offered at a premium,
their effective yields will depend to a significant extent on the rate at which
excess interest materializes and is applied to make distributions of principal
in respect of such Classes of Certificates as described in the preceding
paragraph.

         The weighted average lives of the Regular Certificates may also be
shortened by the exercise of an optional termination right as described under
"DESCRIPTION OF THE CERTIFICATES -- Optional Termination" herein.

         Prepayments on mortgage loans are commonly measured by a prepayment
standard or model. The model used in this Prospectus Supplement (the
"Prepayment Model" or "CPR") represents an assumed constant rate of prepayments
each month, expressed as an annual rate, relative to the then outstanding
principal balance of a pool of mortgage loans for the life of such mortgage
loans. CPR does not purport to be either an historical description of the
prepayment experience of any pool of mortgage loans or a prediction of the
anticipated rate of prepayment of any mortgage loans, including the Mortgage
Loans to be included in the Mortgage Pool.

         The tables of Percentages of Initial Certificate Principal Amount
Outstanding for the Class () and Class () Certificates at the respective
percentages of CPR set forth herein indicate the weighted average life of each
Class of Offered Certificates and set forth the percentage of the initial
certificate principal amount of such Certificates that would be outstanding
after each of the dates shown at the indicated percentages of CPR. The tables
have been prepared on the basis of the "Mortgage Loan Assumptions," which are
the assumptions that the Group (1) (, Group ) and Group () Mortgage Loans
consist of (, ) and subgroups, respectively, (each treated as a single assumed
Mortgage Loan,) with the following characteristics:

                   (DESCRIPTION OF MORTGAGE LOAN ASSUMPTIONS)

         The simplifying assumptions described above that have been made in
preparing the following tables are expected to vary from the actual performance
of the Mortgage Loans. In particular, actual prepayments are not likely to
occur at constant rates or at the assumed rates and the terms of extensions are
not likely to be uniform, and variations in prepayment speeds and extension
terms, even if averaging to the same constant prepayment rate over time and to
the same weighted average extension term, may have different effects on the
payment rates of the Regular Certificates. Furthermore, not all Balloon
Mortgage Loans are expected to be extended or to be extended for the suggested
terms, and prepayments and extensions may apply disproportionately to Mortgage
Loans with different Mortgage Interest Rates. To the extent fixed rate Mortgage
Loans with higher Mortgage Interest Rates prepay at higher rates or are
extended less frequently or for shorter terms, the excess interest available to
make distributions in reduction of the Certificate Principal Amounts of the
Class and Class Certificates may be reduced even at the same constant
prepayment rates. There can be no assurance as to the actual rates of
prepayment or extension of the Mortgage Loans or as to variations in applicable
interest rates.

         Furthermore, the assumptions made in preparing the following tables
vary to some degree from the actual terms of the Regular Certificates and the
Agreement in that: ((i) any extension of a Mortgage Loan will occur only under
circumstances in which such Mortgage Loan has become a Specially Serviced
Mortgage Loan subject to deduction of a Workout Fee from all future Monthly
Payments; (ii) upon extension, and in contrast to the assumptions, some of the
Group (, Group ) and Group Mortgage Loans might not be Discounted Mortgage
Loans and some of the Group Mortgage Loans might be Discounted Mortgage Loans,
depending upon the modified terms thereof; (iii) the actual reduction of the
Scheduled Principal Balance of the Discounted Mortgage Loans will depend on the
modified terms thereof and will not always be % of their Scheduled Principal
Balances; and (iv) the terms of any extension 


                                     S-52
<PAGE>

permitted under the Agreement may require an increase or allow a decrease in
the Mortgage Interest Rate or the Monthly Payment, rather than providing for
continuation of the same terms.)

         Based on the foregoing assumptions, the tables indicate the weighted
average lives of the Regular Certificates (and of the Mortgage Loans) and set
forth in percentages of the initial Certificate Principal Amount of the Regular
Certificates (and of the aggregate Scheduled Principal Balance as of
Cut-Off-Date of the Mortgage Loans) that would be outstanding after the
Distribution Date in of each of the years indicated, at various percentages of
the CPR and years of extension. None of the indicated percentages of CPR
purports to be an historical description of prepayment experience or a
prediction of the anticipated rate of prepayment of the Mortgage Loans included
in the Mortgage Pool. Variations in the actual prepayment experience and
extension experience and the balance of the Mortgage Loans that prepaid or are
extended may increase or decrease the percentage of initial Certificate
Principal Amount (and weighted average life) shown in the following tables.
Such variations may occur even if the average prepayment experience of all such
Mortgage Loans equals any of the specified percentages of the CPR and the
average extension experience of all such Mortgage Loans equals any of the
specified years of extension. In addition, as described above under "THE TRUST
FUND -- General," the Mortgage Loans may be subject to periods of slower
amortization or to negative amortization, in which case the weighted average
lives of the Regular Certificates will be increased, and to periods of
accelerated amortization, in which case the weighted average lives of the
Regular Certificates will be decreased.

         (DECLINING BALANCE AND WEIGHTED AVERAGE LIFE TABLES)

         (1) THE WEIGHTED AVERAGE LIFE OF A REGULAR CERTIFICATE IS DETERMINED
BY (I) MULTIPLYING THE AMOUNT OF EACH DISTRIBUTION IN REDUCTION OF THE
OUTSTANDING CERTIFICATE PRINCIPAL AMOUNT OF SUCH CERTIFICATE BY THE NUMBER OF
YEARS FROM THE DATE OF ISSUANCE OF THE REGULAR CERTIFICATES TO THE RELATED
DISTRIBUTION DATE, (II) ADDING THE RESULTS AND (III) DIVIDING THE SUM BY THE
INITIAL CERTIFICATE PRINCIPAL AMOUNT OF THE REGULAR CERTIFICATE.

                                USE OF PROCEEDS

         (Substantially all of the net proceeds from the sale of the
Certificates will be used by the Depositor (to purchase the Mortgage Collateral
conveyed to the Trustee by the Depositor simultaneously with the issue and sale
of the Certificates (to repay indebtedness incurred to purchase the Mortgage
Collateral) (to pay for the costs of structuring and issuing the Certificates)
(and) (to establish the (specify Reserve Funds)). The Mortgage Collateral (will
be purchased from the Underwriter (or an affiliate of the Underwriter) at a
price negotiated by the (Depositor) (and may not reflect an arm's-length
transaction)) (is owned by the Depositor).)

         (The Certificates are being initially sold and delivered by the
Depositor to () in exchange for the Mortgage Collateral to be conveyed to the
Trustee by the Depositor as Mortgage Collateral for the Series. The Depositor
will receive no other proceeds from the sale of the Certificates. () may
subsequently sell the Certificates in one or more transactions.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         (An election will (not) be made to treat a segregated pool of assets
within the Trust Fund ((excluding the Reserve Fund and the rights of
Certificateholders under certain agreements pursuant to which the beneficial
owner of the Reserve Fund will make payments to the holders of the Regular
Certificates in the event of a Basis Risk Shortfall)) as a REMIC for federal
income tax purposes.) The classes of REMIC interests designated in the
Agreement as the Class of Interests, corresponding to the Class Certificates,
respectively, will be considered to be "regular interests" in a REMIC and will
be referred to herein as "Regular Interests." (The Class R Certificates will be
considered to be the "residual interest" in a REMIC and will be referred to
herein as the "Residual Interest.")

                               REGULAR INTERESTS

         The Regular Interests generally will be treated as newly originated
debt instruments for federal income tax purposes. Holders of the Regular
Interests will be required to report income thereon in accordance with the
accrual method of accounting. It is anticipated that the Class Interests will
be issued with original issue discount for federal 


                                     S-53
<PAGE>

income tax purposes, in an amount equal to the excess of the initial principal
balances of the corresponding Classes of Certificates over their issue prices
(including accrued interest). It is further anticipated that the Class
Interests will be issued at a premium for federal income tax purposes.

         The Prepayment Assumption that is to be used in determining the rate
of accrual of original issue discount and whether the original issue discount
is considered de minimis, and that may be used by a holder of Regular Interests
to amortize premium, will be calculated using . No representation is made as to
the actual rate at which the Mortgage Loans will prepay. RESIDUAL

                                    INTEREST

         The holders of the Class R Certificates must include the taxable
income or loss of the REMIC in determining their federal taxable income. The
Class R Certificates will remain outstanding for federal income tax purposes
until there are no Certificates of any other Class outstanding. Prospective
investors are cautioned that the Class R Certificateholders' REMIC taxable
income and the tax liability thereon will exceed cash distributions to such
holder during certain periods, in which event the holders must have sufficient
alternative sources of funds to pay such tax liability. Furthermore, it is
anticipated that all or a substantial portion of the taxable income of the
REMIC includible by a holder of a Class R Certificate will be treated as
"excess inclusion" income resulting in (i) the inability of such holder to use
net operating losses to offset such taxable income, (ii) the treatment of such
taxable income as "unrelated business taxable income" to certain holders who
are otherwise tax-exempt and (iii) the treatment of such taxable income as
subject to 30% withholding tax to certain non-U.S. investors, with no exemption
or treaty reduction.

         In addition, under the REMIC Regulations, the Class R Certificates
will be considered "noneconomic residual interests," with the result that
transfers thereof would be disregarded for federal income tax purposes if any
significant purpose of any such transfer was to impede the assessment or
collection of tax. Accordingly, the transferee affidavit used for transfers of
a Class R Certificate will require the transferee to state, among other things,
that it has no intention to impede the assessment or collection of any federal,
state or local income taxes legally required to be paid with respect to the
Class R Certificate and that it will not transfer the Class R Certificate to
any Person that it has reason to believe has the intention to impede the
assessment or collection of such taxes. Finally, the Class R Certificates
generally may not be transferred to Persons who are not U.S. Persons. See
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES -- Taxation of Residual Interests --
Limitations on Offset or Exemption of REMIC Income" and "--Tax-Related
Restrictions on Transfer of Residual Interests -- Noneconomic Residual
Interests" in the Prospectus.

         An individual, trust or estate that holds a Class R Certificate
(whether such Certificate is held directly or indirectly through certain
Pass-Through Entities) also may have additional gross income with respect to,
but may be subject to limitations on the deductibility of the fees of the
Master Servicer and the Special Servicer paid from the REMIC Pool and other
administrative expenses of the REMIC Pool in computing such holder's regular
tax liability, and may not be able to deduct such fees or expenses to any
extent in computing such holder's alternative minimum tax liability. In
addition, some portion of a holder's basis, if any, in a Class R Certificate
may not be recovered until termination of the REMIC. Furthermore, the federal
income tax consequences of any consideration paid to a transferee on a transfer
of a Class R Certificate are unclear; therefore, any such transferee receiving
such consideration should consult its tax advisers. See "CERTAIN FEDERAL INCOME
TAX CONSEQUENCES -- Taxation of Residual Interests -- Tax-Related Restrictions
on Transfer of Residual Interests" and "--Limitations of Deductions of Certain
Expenses" in the Prospectus.

         DUE TO THE SPECIAL TAX TREATMENT OF RESIDUAL INTERESTS, THE EFFECTIVE
AFTER-TAX RETURN OF THE CLASS R CERTIFICATES MAY BE SIGNIFICANTLY LOWER THAN
WOULD BE THE CASE IF THE CLASS R CERTIFICATES WERE TAXED AS DEBT INSTRUMENTS.

                              ERISA CONSIDERATIONS

         Any fiduciary of an employee benefit or other plan subject to the 
fiduciary responsibility rules of Title I of ERISA or Section 4975 of the Code 
(a "Plan") who proposes to cause a Plan to acquire any of the Offered 
Certificates, should consult with its counsel with respect to the potential 
consequences under ERISA and the Code of the Plan's acquisition and ownership 
of such Certificates.



                                     S-54
<PAGE>

         The U.S. Department of Labor has granted to CS First Boston
Corporation (the former name of Credit Suisse First Boston Corporation) an
administrative exemption (Prohibited Transaction Exemption 89-90, as amended;
referred to herein as the "Exemption") from certain of the prohibited
transaction rules of ERISA and the related excise tax provisions of Section
4975 of the Code with respect to the initial purchase, the holding and
subsequent resale by Plans of certificates evidencing an interest in
pass-through trusts that consist of certain receivables, loans, and other
obligations that meet the conditions and requirements of the Exemption.

         The Exemption covers certificates evidencing an interest in a trust
consisting of obligations that bear interest or are purchased at a discount and
which are secured, such as mortgages secured by commercial or multifamily real
property. Among the other conditions that must be satisfied for the Exemption
to apply are the following:

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

         (2) The rights and interests evidenced by the certificates acquired by
the Plan are not subordinated to the rights and interests evidenced by other
certificates of the trust;

         (3) The certificates acquired by the Plan have received a rating at
the time of such acquisition that is one of the three highest generic rating
categories from Moody's, S&P, DCR or Fitch;

         (4) The trustee is not an affiliate of any member of the Restricted
Group (as defined below);

         (5) The sum of all payments made to and retained by the underwriters
in connection with the distribution of certificates represents not more than
reasonable compensation for underwriting the certificates. The sum of all
payments made to and retained by the seller pursuant to the assignment of the
obligations to the trust fund represents not more than the fair market value of
such obligations. The sum of all payments made to and retained by the servicer
represents not more than reasonable compensation for such person's services
under the pooling and servicing agreement and reimbursement of such person's
reasonable expenses in connection therewith; and

         (6) The Plan investing in the certificates is an "accredited investor"
as defined in Rule 501(a)(1) of Regulation D of the Commission under the Act.

         In order for the Exemption to apply, the trust fund must also meet the
following requirements:

         (1) The corpus of the trust fund must consist solely of assets of a
type that have been included in other investment pools;

         (2) Certificates in such other investment pools must have been rated
in one of the three highest generic rating categories of Moody's, S&P, DCR or
Fitch for at least one year prior to the Plan's acquisition of certificates;
and

         (3) Certificates evidencing interests in such other investment pools
must have been purchased by investors other than Plans for at least one year
prior to any Plan's acquisition of certificates.

         In addition, the Exemption will not apply to a Plan's investment in
certificates if the Plan fiduciary responsible for the decision to invest in
the certificates is (a) an obligor with respect to more than five percent of
the fair market value of the obligations constituting the assets of the trust
or (b) an affiliate of such person, unless: (i) in the case of an acquisition
in connection with the initial issuance of certificates, at least fifty percent
of each class of certificates in which Plans have invested is acquired by
persons independent of the Restricted Group and at least fifty percent of the
aggregate interest in the trust is acquired by persons independent of the
Restricted Group; (ii) the Plan's investment in certificates of any class does
not exceed twenty-five percent of all of the certificates of that class
outstanding at the time of the acquisition; (iii) immediately after the
acquisition, no more than twenty-five percent of the assets of the Plan with
respect to which such person is a fiduciary are invested in certificates
representing an interest in one or more trusts containing assets sold or
serviced by the same entity; and (iv) the Plan is not sponsored by the
Depositor, the Underwriters, the Trustee, the Master Servicer, the Special
Servicer, any obligor with respect to Mortgage Loans included in the Trust Fund
constituting more than five percent of the aggregate unamortized principal
balance of the 


                                     S-55
<PAGE>

assets in the Trust Fund on the date of the initial issuance of Certificates, 
or any affiliate of such parties (the "Restricted Group").

         If the conditions of the Exemption are met, whether or not a Plan's
assets would be deemed to include an ownership interest in the Mortgage Loans,
the acquisition, holding and resale of the Class () Certificates by Plans would
be exempt from many of the prohibited transaction provisions of ERISA and 
Section 4975 of the Code.

         (The Underwriters believe that the factual conditions to the
availability of the Exemption will be met in connection with the acquisition
and holding of the Class () Certificates by Plans, assuming that all conditions
of the Exemption within the control of a particular investor (or its fiduciary)
will have been met. In that regard,) (A)s of the date hereof there is no single
obligor with respect to Mortgage Loans included in the Trust Fund that
constitute more than five percent of the aggregate unamortized principal
balance of the assets of the Trust Fund, but no assurance can be given that
there does not exist an affiliated group of obligors on Mortgage Loans that
constitute more than five percent of such balance.

         Prospective Plan investors should consult with their legal advisers
concerning the impact of ERISA and the Code, the applicability of the
Exemption, and the potential consequences in their specific circumstances,
prior to making an investment in the Class () Certificates. Moreover, each Plan
fiduciary should determine whether under the general fiduciary standards of
investment prudence and diversification an investment in the Class ()
Certificates is appropriate for the Plan, taking into account the overall
investment policy of the Plan and the composition of the Plan's investment
portfolio. (THE CHARACTERISTICS OF THE CLASS () CERTIFICATES MAY NOT MEET THE
REQUIREMENTS OF THE EXEMPTION. ACCORDINGLY, THE CLASS (), CERTIFICATES SHOULD
NOT BE ACQUIRED BY A PLAN OR WITH ASSETS OF ANY PLAN.)

         Subordinated Certificates are not available for purchase by or with
"plan assets" of any Plan, other than an insurance company general account
which satisfies the conditions set forth in Sections I and II of PTCE 95-60 or
a governmental or church plan which is not subject to ERISA or Section 4975 of
the Code (as described above), and any acquisition of Subordinate Certificates
by, on behalf of or with "plan assets" of any such Plan will be treated as null
and void for all purposes.

INSURANCE COMPANY GENERAL ACCOUNTS

         In addition to any exemption that may be available under PTCE 95-60
for the purchase and holding of the Certificates by an insurance company
general account, the Small Business Job Protection Act of 1996 added a new
Section 401(c) to ERISA, which provides certain exemptive relief from the
provisions of Part 4 of Title I of ERISA and Section 4975 of the Code,
including the prohibited transaction restrictions imposed by ERISA and the
related excise taxes imposed by Section 4975 of the Code, for transactions
involving an insurance company general account. Pursuant to Section 401(c) of
ERISA, the DOL was required to issue final regulations (the "401(c)
Regulations") no later than December 31, 1997 which are to provide guidance for
the purpose of determining, in cases where insurance policies or annuity
contracts 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." The DOL issued proposed regulations under Section
401(c) on December 22, 1997, but the final 401(c) Regulations have not been
issued as of the date hereof. 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 Certificates should consult with their legal counsel with respect to the
applicability of Sections I and III of PTCE 95-60 and Section 401(c) or ERISA,
including the general account's ability to continue to hold the Certificates
after the date which is 18 months after the date the 401(c) Regulations become
final.

         ANY PLAN INVESTOR WHO PROPOSES TO USE "PLAN ASSETS" OF ANY PLAN TO
PURCHASE CERTIFICATES OF ANY SERIES OR CLASS SHOULD CONSULT WITH ITS COUNSEL
WITH RESPECT TO THE POTENTIAL CONSEQUENCES UNDER ERISA AND SECTION 4975 OF THE
CODE OF THE ACQUISITION AND OWNERSHIP OF SUCH CERTIFICATES.


                        LEGAL INVESTMENT CONSIDERATIONS

         (The Class () Certificates will constitute "mortgage related
securities" for purposes of the Enhancement Act.) The (other Classes of)
Offered Certificates will not constitute "mortgage related securities" under
the Enhancement Act. For additional information concerning investment

There is currently no secondary market for the Offered Certificates. The
Underwriters, either directly or through their affiliates, intend to make a
secondary market in the Offered Certificates, but none of the Underwriters has
any obligation to do so. There can be no assurance that an active secondary
market for any of the Offered Certificates will develop or that any such
market, if established, will continue.

         The Underwriters propose to offer each Class of the Offered
Certificates in part directly to purchasers at the initial public offering
prices set forth on the cover page of this Prospectus Supplement, and in part
to certain securities dealers at such prices less the concessions set forth
below for each such Class. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of the amount set forth below for each such
Class. After the Offered Certificates are released for sale to the public, the
public offering prices and other selling terms may be changed by the
Underwriters.

                              CERTIFICATE RATINGS

         (It is a condition to the issuance of the Certificates that they be
rated in one of the four highest rating categories by at least one Rating
Agency.) It is a condition to the issuance of the Offered Certificate that the
Class Certificates be rated no lower than " " by (Moody's) (Fitch) (S&P) (DCR),
that the Class Certificates be rated no lower than " " by and " " by and that
the Class Certificates be rated no lower than " " by and " " by . (While it is
not a condition to the issuance of any of the Certificates, it is expected that
the Class Certificates will be rated no lower than " " by and " " by .)

         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. The security rating assigned to the Offered
Certificates should be evaluated independently of similar security ratings
assigned to other kinds of securities.

         (The ratings of Moody's on mortgage pass-through certificates address
the likelihood of the receipt by certificate holders of all distributions to
which such certificate holders are entitled. Moody's rating opinions address
the structural, legal, issuer and tax-related aspects associated with the
certificates, including the nature of the underlying mortgage loans and the
credit quality of the credit support provided, if any. Moody's ratings on
pass-through certificates do not represent any assessment of the likelihood
that principal prepayments may differ from those originally anticipated.)

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

         (The ratings assigned by Fitch to mortgage pass-through certificates
address the likelihood of the receipt by certificate holders of all
distributions to which such certificate holders are entitled. The rating
process addressed the structural, legal and issuer-related aspects associated
with the certificates, including the nature of the underlying mortgage loans.
The ratings assigned to mortgage pass-through certificates by Fitch do not
represent any assessment of the likelihood or rate of principal prepayments.
The ratings do not address the possibility that certificate holders might
receive a lower than expected yield.)

         (The ratings assigned by DCR to mortgage pass-through certificates
address the likelihood of the receipt by certificate holders of all
distributions to which such certificate holders are entitled. The ratings
assigned to mortgage pass-through certificates by DCR do not constitute a
statement regarding the frequency or extent of principal prepayments. The
ratings do not address the possibility that certificate holders might receive a
lower than expected yield.)

         The Depositor will request a rating of the Offered Certificates by one
or more Rating Agencies. There can be no assurance as to whether any rating
agency not requested to rate the Offered Certificates will nonetheless issue a
rating and, if so, what such rating would be. A rating assigned to the Offered
Certificates by a rating agency that has not been requested by the Depositor to
do so may be lower than the rating assigned by a Rating Agency pursuant to the
Depositor's request.

                                 LEGAL MATTERS

         The legality of the Certificates will be passed upon for the Depositor
and the Underwriter by (Brown & Wood LLP)(Cadwalader, Wickersham &
Taft)(Orrick, Herrington & Sutcliffe LLP), New York, New York. The material
federal income tax consequences of the Certificates will be passed upon for the

                             MORTGAGE LOAN EXHIBITS

         The information set forth in Exhibits X through Z is based on
Scheduled Principal Balances, Mortgage Interest Rates and other information as
of _______ 1, 199__ with respect to mortgage loans expected to be included in
the Trust Fund. Not all the mortgage loans upon which Exhibits through are
based may be included in the Trust Fund and consequently the information set
forth below may vary from comparable information on the Mortgage Loans
ultimately included in the Trust Fund. In addition, the information set forth
below may change as a result of principal payments, Mortgage Interest Rate
adjustments and other factors relating to the Mortgage Loans prior to the
Closing Date. The Seller will file a report on Form 8-K with the Commission in
accordance with the rules thereof which will set forth information with respect
to the Mortgage Loans included in the Trust Fund on the Closing Date. As to
each item the chart will set forth the number of mortgage loans, the Aggregate
Unpaid Principal Balance as of the Cut-Off-Date and the Percentage of Aggregate
Unpaid Principal Balance. The information expressed as a Percentage of the
Aggregate Unpaid Principal Balance may not total 100% due to rounding, and the
sum of the amounts listed as the Aggregate Unpaid Principal Balance of the
Mortgage Loans as of the Cut-Off-Date may not total the indicated amount due to
rounding. For purposes of the following exhibits, weighted average original
term calculations do not include contractual extensions.

                   AVAILABLE DEBT SERVICE COVERAGE RATIOS (1)

Group Mortgage Loans
Group Mortgage Loans
Group Mortgage Loans

(1) The debt service coverage ratio of a Mortgage Loan is the ratio of annual
net operating income generated by the Mortgage Property before payment of any
debt service on the Mortgage Loan to the annual debt service on such Mortgage
Loans.

(2) The calculation of the debt service coverage ratios set forth in the table
was based upon the ratio of net operating income, derived from information for
a period ending in or later, to, generally, the annualized Monthly Payment in
effect as of the Cut-Off-Date.

(3) The data are derived from (i) operating statements provided by the
Borrowers adjusted in some instances as described below and (ii) operating
information provided by appraisals dated or later.

         The weighted average debt service coverage is and times for the Group
and Group Mortgage Loans, respectively, for which operating information is
available.

         For Group Mortgage Loans the Depositor obtained property operating
statements or operating information for minimum (nine-month) periods ending in
or later from Borrowers whose Mortgage Loans represented approximately ___% of
the aggregate Scheduled Principal Balance of the Group Mortgage Loans as of the
Cut-Off-Date. In some instances, non-material adjustments were made to such
operating statements and operating information, resulting in an increase or
decrease in the net operating income stated therein, based upon the Depositor's
evaluation of such operating statements and operating information and the
assumptions applied by the Borrower in preparing such statements and
information. No assurance can be given with respect to the accuracy of the
information provided by any Borrower, or the results of any adjustments thereto
by or on behalf of the Depositor, concerning the operating income derived from
any Mortgaged Property. In addition, since Borrowers under the remaining
Mortgage Loans have not been determined or inferred, and no assurance can be
given that the information set forth in the table is representative of those
Mortgage Loans

         The operating information supplied by Borrowers and used by the
Depositor to calculate debt service coverage ratios may be for periods that
ended as long ago as. The Depositor does not have information as to the current
levels of rental income generated by the Mortgaged Properties for which it had
obtained operating information, and current rental income on a significant
portion of such Mortgaged Properties may have changed as a result of changes in
occupancy rates and levels of rent on space that is occupied. Accordingly, debt
service coverage ratios for the Mortgage Loans for which such ratios are set
forth in the table above may have changed substantially since the end of the
period for which such ratios were calculated.

Because debt service coverage ratios were not calculated with respect to the
remaining Mortgage Loans representing approximately % of the aggregate
Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off-Date, no
assurance can be given that the information set forth in the above table is
representative of such Mortgage Loans or that such remaining Mortgage Loans do
not include Mortgage Loans with debt service coverage ratios equal to or lower
than those of the Mortgage Loans for which such ratios were calculated.
Because, among other things, of the lack of uniformity in the data underlying
the debt service coverage ratio information contained herein and the absence of
independent verification of such data, there can be no assurance that the
information derived from the sample is representative of similar information
which would have been developed had operating information been available for
all the Mortgage Loans. Moreover, if the sample is representative of the
Mortgage Loans, the Trust Fund includes Mortgage Loans with debt service
coverage ratios of less than break-even that were not included in the sample.
In any event, prospective investors should consider the Mortgage Loans to be
nonrecourse loans as to which, in the event of a Borrower default, recourse may
be had only against the specific (commercial and/or multifamily residential)
property pledged to secure that Mortgage Loan (and not against the Borrower's
other assets).

           COMMERCIAL/MULTIFAMILY MORTGAGE PASS-THROUGH CERTIFICATES

                              (Issuable in Series)

                                 -------------

Credit Suisse First Boston Mortgage Securities Corp. (the "Depositor") from
time to time will offer Commercial/Multifamily Mortgage Pass-Through
Certificates (the "Certificates") in "Series" by means of this Prospectus and a
separate Prospectus Supplement for each Series. The Certificates of each Series
will evidence beneficial ownership interests in a trust fund (the "Trust Fund")
to be established by the Depositor. The Certificates of a Series may be divided
into two or more "Classes" which may have different interest rates and which
may receive principal payments in differing proportions and at different times.
In addition, rights of the holders of certain Classes to receive principal and
interest may be subordinated to those of other Classes.

Each Trust Fund will consist of a pool (the "Mortgage Pool") of one or more
mortgage loans secured by first or junior liens on commercial real estate
properties, multifamily residential properties, cooperatively owned multifamily
properties and/or mixed residential/commercial properties, and related property
and interests, conveyed to such Trust Fund by the Depositor, and other assets,
including any reserve funds established with respect to a Series, insurance
policies on the Mortgage Loans, letters of credit, certificate guarantee
insurance policies or other enhancement described in the related Prospectus
Supplement. If so specified in the related Prospectus Supplement, the Mortgage
Pool may also include participation interests in such types of mortgage loans,
installment contracts for the sale of such types of properties and/or mortgage
pass-through certificates. Such mortgage loans, participation interests,
mortgage pass-through certificates and installment contracts are hereinafter
referred to as the "Mortgage Loans." "The Mortgage Loans will have fixed or
adjustable interest rates. Some Mortgage Loans will fully amortize over their
remaining terms to maturity and others will provide for balloon payments at
maturity. The Mortgage Loans will provide for recourse against only the
Mortgaged Properties or provide for recourse against the other assets of the
obligors thereunder. The Mortgage Loans will be newly originated or seasoned,
and will be acquired by the Depositor either directly or through one or more
affiliates. Information regarding each Series of Certificates, including
interest and principal payment provisions for each Class, as well as
information regarding the size, composition and other characteristics of the
Mortgage Pool relating to such Series, will be furnished in the related
Prospectus Supplement. The Mortgage Loans will be serviced by a Master Servicer
identified in the related Prospectus Supplement.

The Certificates do not represent an obligation of or an interest in the
Depositor or any affiliate thereof. Unless so specified in the related
Prospectus Supplement, neither the Certificates nor the Mortgage Loans are
insured or guaranteed by any governmental agency or instrumentality or by any
other person or entity.

The Depositor, as specified in the related Prospectus Supplement, may elect to
treat all or a specified portion of the collateral securing any Series of
Certificates as a "real estate mortgage investment conduit" (a "REMIC"), or an
election may be made to treat the arrangement by which a Series of Certificates
is issued as a REMIC. If such election is made, each Class of Certificates of a
Series will be either Regular Interest Certificates or Residual Interest
Certificates (each, as defined herein), as specified in the related Prospectus
Supplement. If no such election is made, the Trust Fund, as specified in the
related Prospectus Supplement, will be classified as a grantor trust for
federal income tax purposes. See "Certain Federal Income Tax Consequences."


                                 -------------

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.

PROSPECTIVE INVESTORS SHOULD REVIEW THE INFORMATION APPEARING UNDER THE CAPTION
"RISK FACTORS" AFTER THE SECTION CAPTIONED "INCORPORATION OF CERTAIN
INFORMATION BY REFERENCE" HEREIN.

Offers of the Certificates may be made through one or more different methods,
including offerings through underwriters, which may include Credit Suisse First
Boston Corporation, an affiliate of the Depositor, as more fully described
under "Plan of Distribution" herein and in the related Prospectus Supplement.
Certain offerings of the Certificates, as specified in the related Prospectus
Supplement, may be made in one or more transactions exempt from the
registration requirements of the Securities Act of 1933, as amended. Such
offerings are not being made pursuant to the Registration Statement of which
this Prospectus forms a part.

There will have been no public market for the Certificates of any Series prior
to the offering thereof. No assurance can be given that such a market will
develop as a result of such offering or, if it does develop, that it will
continue.

This Prospectus may not be used to consummate sales of the Certificates offered
hereby unless accompanied by a Prospectus Supplement.

               INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

There are incorporated herein by reference all documents and reports filed or
caused to be filed by the Depositor with respect to a Trust Fund pursuant to
Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, prior

                                  RISK FACTORS

         INVESTORS SHOULD CONSIDER, IN CONNECTION WITH THE PURCHASE OF
CERTIFICATES, AMONG OTHER THINGS, THE FOLLOWING FACTORS AND CERTAIN OTHER
FACTORS AS MAY BE SET FORTH IN "RISK FACTORS" IN THE RELATED PROSPECTUS
SUPPLEMENT.

         Limited Liquidity. There can be no assurance that a secondary market
for the Certificates of any Series will develop or, if it does develop, that it
will provide holders with liquidity of investment or will continue while
Certificates of such Series remain outstanding. Any such secondary market may
provide less liquidity to investors than any comparable market for securities
evidencing interests in single family mortgage loans. The market value of
Certificates will fluctuate with changes in prevailing rates of interest.
Consequently, sale of Certificates by a holder in any secondary market that may
develop may be at a discount from 100% of their original principal balance or
from their purchase price. Furthermore, secondary market purchasers may look
only hereto, to the related Prospectus Supplement and to the reports to
Certificateholders delivered pursuant to the related Agreement. Except to the
extent described herein and in the related Prospectus Supplement,
Certificateholders will have no redemption rights and the Certificates are
subject to early retirement only under certain specified circumstances
described herein and in the related Prospectus Supplement.

         Limited Assets. The Certificates will not represent an interest in or
obligation of the Depositor, the Master Servicer, or any of their affiliates.
The only obligations with respect to the Certificates or the Mortgage Loans
will be the obligations (if any) of the Depositor (or, if otherwise provided in
the related Prospectus Supplement, the person identified therein as the person
making certain representations and warranties with respect to the Mortgage
Loans, as applicable) pursuant to certain limited representations and
warranties made with respect to the Mortgage Loans. Since certain
representations and warranties with respect to the Mortgage Loans may have been
made and/or assigned in connection with transfers of such Mortgage Loans prior
to the Closing Date, the rights of the Trustee and the Certificateholders with
respect to such representations or warranties will be limited to their rights
as an assignee thereof. Unless otherwise specified in the related Prospectus
Supplement, none of the Depositor, the Master Servicer or any affiliate thereof
will have any obligation with respect to representations or warranties made by
any other entity. Unless otherwise specified in the related Prospectus
Supplement, neither the Certificates nor the underlying Mortgage Loans will be
guaranteed or insured by any governmental agency or instrumentality, or by the
Depositor, the Master Servicer or any of their affiliates. Proceeds of the
assets included in the related Trust Fund for each Series of Certificates
(including the Mortgage Loans and any form of Enhancement) will be the sole
source of payments on the Certificates, and there will be no


                                       3
<PAGE>

recourse to the Depositor or any other entity in the event that such proceeds
are insufficient or otherwise unavailable to make all payments provided for
under the Certificates.

         Unless otherwise specified in the related Prospectus Supplement, a
Series of Certificates will not have any claim against or security interest in
the Trust Funds for any other Series. If the related Trust Fund is insufficient
to make payments on such Certificates, no other assets will be available for
payment of the deficiency. Additionally, certain amounts remaining in certain
funds or accounts, including the Distribution Account, the Collection Account
and the REO Account and any accounts maintained as Enhancement, may be
withdrawn under certain conditions, as described in the related Prospectus
Supplement. In the event of such withdrawal, such amounts will not be available
for future payment of principal of or interest on the Certificates. If so
provided in the Prospectus Supplement for a Series of Certificates that
includes one or more classes of Subordinate Certificates, on any Distribution
Date in respect of which losses or shortfalls in collections on the Trust Funds
have been incurred, the amount of such losses or shortfalls will be borne first
by one or more classes of the Subordinate Certificates, and, thereafter, by the
remaining classes of Certificates in the priority and manner and subject to the
limitations specified in such Prospectus Supplement.

         Prepayments and Effect on Average Life of Certificates and Yields.
Prepayments (including those caused by defaults) on the Mortgage Loans in any
Trust Fund generally will result in a faster rate of principal payments on one
or more classes of the related Certificates than if payments on such Mortgage
Loans were made as scheduled. Thus, the prepayment experience on the Mortgage
Loans may affect the average life of each class of related Certificates. The
rate of principal payments on pools of mortgage loans varies between pools and
from time to time is influenced by a variety of economic, demographic,
geographic, social, tax, legal and other factors. There can be no assurance as
to the rate of prepayment on the Mortgage Loans in any Trust Fund or that the
rate of payments will conform to any model described herein or in any
Prospectus Supplement. If prevailing interest rates fall significantly below
the applicable mortgage interest rates, principal prepayments are likely to be
higher than if prevailing rates remain at or above the rates borne by the
Mortgage Loans underlying or comprising the Mortgaged Properties in any Trust
Fund. As a result, the actual maturity of any class of Certificates could occur
significantly earlier than expected. A Series of Certificates may include one
or more classes of Certificates with priorities of payment and, as a result,
yields on other classes of Certificates of such Series may be more sensitive to
prepayments on Mortgage Loans. A Series of Certificates may include one or more
classes offered at a significant premium or discount. Yields on such classes of
Certificates will be sensitive, and in some cases extremely sensitive, to
prepayments on Mortgage Loans and, where the amount of interest payable with
respect to a class is disproportionately high, as compared to the amount of
principal, as with certain classes of Stripped Certificates, a holder might, in
some prepayment scenarios, fail to recoup its original investment. A Series of
Certificates may include one or more classes of Certificates that provide for
distribution of principal thereof from amounts attributable to interest accrued
but not currently distributable on one or more classes of Certificates (the
"Accrual Certificates") and, as a result, yields on such Certificates will be
sensitive to (a) the provisions of such Accrual Certificates relating to the
timing of distributions of interest thereon and (b) if such Accrual
Certificates accrue interest at a variable or floating Pass-Through Rate,
changes in such rate.

         Limited Nature of Ratings. Any rating assigned by a Rating Agency to a
class of Certificates will reflect such Rating Agency's assessment solely of
the likelihood that holders of Certificates of such class will receive payments
to which such Certificateholders are entitled under the related Agreement. Such
rating will not constitute an assessment of the likelihood that principal
prepayments (including those caused by defaults) on the related Mortgage 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 Certificates. 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


                                       4

or that an investor purchasing a Certificate at a significant premium might
fail to recoup its initial investment under certain prepayment scenarios. Each
Prospectus Supplement will identify any payment to which holders of
Certificates of the related Series are entitled that is not covered by the
applicable rating.

         The amount, type and nature of any Enhancement established with
respect to a Series of Certificates 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 support 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 Mortgage Loans. No assurance can be given that values of any Mortgaged
Properties have remained or will remain at their levels on the respective dates
of origination of the related Mortgage Loans. Moreover, there is no assurance
that appreciation of real estate values generally will limit loss experiences
on the Mortgaged Properties. If the commercial or multifamily residential real
estate markets should experience an overall decline in property values such
that the outstanding principal balances of the Mortgage Loans underlying or
comprising the Mortgage Loans in a particular Trust Fund and any secondary
financing on the related Mortgaged Properties become equal to or greater than
the value of the Mortgaged Properties, the rates of delinquencies, foreclosures
and losses could be higher than those now generally experienced by
institutional lenders. 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 Mortgage
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 Enhancement, if any, described in the related Prospectus Supplement, such
losses will be borne, at least in part, by the holders of one or more classes
of the Certificates of the related Series.

         Risks Associated with Mortgage Loans and Mortgaged Properties.
Mortgage loans made with respect to multifamily or commercial property may
entail risks of delinquency and foreclosure, and risks of loss in the event
thereof, that are greater than similar risks associated with single family
property. The ability of a mortgagor to repay a loan secured by an
income-producing property typically is dependent primarily upon the successful
operation of such property rather than any independent income or assets of the
mortgagor; thus, the value of an income-producing property is directly related
to the net operating income derived from such property. In contrast, the
ability of a mortgagor to repay a single family loan typically is dependent
primarily upon the mortgagor's household income, rather than the capacity of
the property to produce income; thus, other than in geographical areas where
employment is dependent upon a particular employer or an industry, the
mortgagor's income tends not to reflect directly the value of such property. A
decline in the net operating income of an income-producing property will likely
affect both the performance of the related loan as well as the liquidation
value of such property, whereas a decline in the income of a mortgagor on a
single family property will likely affect the performance of the related loan
but may not affect the liquidation value of such property. Moreover, a decline
in the value of a Mortgaged Property will increase the risk of loss
particularly with respect to any related junior Mortgage Loan.

         The performance of a mortgage loan secured by an income-producing
property leased by the mortgagor to tenants as well as the liquidation value of
such property may be dependent upon the business operated by such tenants in
connection with such property, the creditworthiness of such tenants or both.
The risks associated with such loans may be offset by the number of tenants or,
if applicable, a diversity of types of business operated by such tenants.



                                       5
<PAGE>

         It is anticipated that a substantial portion of the Mortgage Loans
included in any Trust Fund will be nonrecourse loans or loans for which
recourse may be restricted or unenforceable, as to which, in the event of a
mortgagor's default, recourse may be had only against the specific property and
such other assets, if any, as have been pledged to secure the related Mortgage
Loan. With respect to those Mortgage Loans that provide for recourse against
the mortgagor and its assets generally, there can be no assurance that such
recourse will ensure a recovery in respect of a defaulted Mortgage Loan greater
than the liquidation value of the related Mortgaged Property.

         Further, the concentration of default, foreclosure and loss risks in
individual mortgagors or Mortgage Loans in a particular Trust Fund or the
related Mortgaged Properties will generally be greater than for pools of single
family loans both because the Mortgage Loans in a Trust Fund will generally
consist of a smaller number of loans than would a single family pool of
comparable aggregate unpaid principal balance and because of the higher
principal balance of individual Mortgage Loans. Mortgage Loans in a Trust Fund
may consist of only a single or limited number of Mortgage Loans and/or relate
to Leases to only a single Lessee or a limited number of Lessees.

         If applicable, certain legal aspects of the Mortgage Loans for a
Series of Certificates may be described in the related Prospectus Supplement.

         Risks Associated with Mortgage Loans and Leases. If so described in
the related Prospectus Supplement, each mortgagor under a Mortgage Loan may be
an entity created by the owner or purchaser of the related Mortgaged Property
solely to own or purchase such property, in part to isolate the property from
the debts and liabilities of such owner or purchaser. Unless otherwise
specified, each such Mortgage Loan will represent a nonrecourse obligation of
the related mortgagor secured by the lien of the related Mortgage and the
related Lease assignments. Whether or not such loans are recourse or
nonrecourse obligations, it is not expected that the mortgagors will have any
significant assets other than the Mortgaged Properties and the related Leases,
which will be pledged to the Trustee under the related Agreement. Therefore,
the payment of amounts due on any such Mortgage Loans, and, consequently, the
payment of principal of and interest on the related Certificates, will depend
primarily or solely on rental payments by the Lessees. Such rental payments
will, in turn, depend on continued occupancy by, and/or the creditworthiness
of, such Lessees, which in either case may be adversely affected by a general
economic downturn or an adverse change in their financial condition. Moreover,
to the extent a Mortgaged Property was designed for the needs of a specific
type of tenant (e.g., a nursing home, hotel or motel), the value of such
property in the event of a default by the Lessee or the early termination of
such Lease may be adversely affected because of difficulty in re-leasing the
property to a suitable substitute lessee or, if re-leasing to such a substitute
is not possible, because of the cost of altering the property for another more
marketable use. As a result, without the benefit of the Lessee's continued
support of the Mortgaged Property, and absent significant amortization of the
Mortgage Loan, if such loan is foreclosed on and the Mortgaged Property is
liquidated following a lease default, the net proceeds might be insufficient to
cover the outstanding principal and interest owing on such loan, thereby
increasing the risk that holders of the Certificates will suffer some loss.

         Balloon Payments. Certain of the Mortgage Loans (the "Balloon Mortgage
Loans") as of the Cut-Off Date may not be fully amortizing over their terms to
maturity and, thus, will require substantial principal payments (i.e., balloon
payments) at their stated maturity. Mortgage Loans with balloon payments
involve a greater degree of risk because the ability of a mortgagor to make a
balloon payment typically will depend upon its ability either to timely
refinance the loan or to timely sell the related Mortgaged Property. The
ability of a mortgagor to accomplish either of these goals will be affected by
a number of factors, including the level of available mortgage interest rates
at the time of sale or refinancing, the mortgagor's equity in the related
Mortgaged Property, the financial condition and operating history of the
mortgagor and the related Mortgaged Property, tax laws, rent control laws (with


                                       6
<PAGE>

respect to certain multifamily properties and mobile home parks), reimbursement
rates (with respect to certain nursing homes), renewability of operating
licenses, prevailing general economic conditions and the availability of credit
for commercial or multifamily real properties, as the case may be, generally.

         Junior Mortgage Loans. To the extent specified in the related
Prospectus Supplement, certain of the Mortgage Loans may be secured primarily
by junior mortgages. In the case of liquidation, Mortgage Loans secured by
junior mortgages are entitled to satisfaction from proceeds that remain from
the sale of the related Mortgaged Property after the mortgage loans senior to
such Mortgage Loans have been satisfied. If there are not sufficient funds to
satisfy such junior Mortgage Loans and senior mortgage loans, such Mortgage
Loan would suffer a loss and, accordingly, one or more classes of Certificates
would bear such loss. Therefore, any risks of deficiencies associated with
first Mortgage Loans will be greater with respect to junior Mortgage Loans.

         Obligor Default. If so specified in the related Prospectus Supplement,
in order to maximize recoveries on defaulted Mortgage Loans, a Master Servicer
or a Special Servicer will be permitted (within prescribed parameters) to
extend and modify Mortgage Loans that are in default or as to which a payment
default is imminent, including in particular with respect to balloon payments.
In addition, a Master Servicer or a Special Servicer may receive a workout fee
based on receipts from or proceeds of such Mortgage Loans. While any such
entity generally will be required to determine that any such extension or
modification is reasonably likely to produce a greater recovery on a present
value basis than liquidation, there can be no assurance that such flexibility
with respect to extensions or modifications or payment of a workout fee will
increase the present value of receipts from or proceeds of Mortgage Loans that
are in default or as to which a payment default is imminent. Additionally, if
so specified in the related Prospectus Supplement, certain of the Mortgage
Loans included in the Mortgage Pool for a Series may have been subject to
workouts or similar arrangements following periods of delinquency and default.

         Mortgagor Type. Mortgage Loans made to partnerships, corporations or
other entities may entail risks of loss from delinquency and foreclosure that
are greater than those of Mortgage Loans made to individuals. The mortgagor's
sophistication and form of organization may increase the likelihood of
protracted litigation or bankruptcy in default situations.

         Enhancement Limitations. The Prospectus Supplement for a Series of
Certificates will describe any Enhancement in the related Trust Fund, which may
include letters of credit, insurance policies, guarantees, reserve funds or
other types of credit support, or combinations thereof. The use of Enhancement
will be subject to the conditions and limitations described herein and in the
related Prospectus Supplement. Moreover, such Enhancement may not cover all
potential losses or risks. For example, Enhancement may or may not cover fraud
or negligence by a mortgage loan originator or other parties.

         A Series of Certificates may include one or more classes of
Subordinate Certificates, if so provided in the related Prospectus Supplement.
Although subordination is intended to reduce the risk to holders of Senior
Certificates of delinquent distributions or ultimate losses, the amount of
subordination will be limited and may decline under certain circumstances. In
addition, if principal payments on one or more classes of Certificates of a
Series are made in a specified order of priority, any limits with respect to
the aggregate amount of claims under any related Enhancement may be exhausted
before the principal of the lower priority classes of Certificates of such
Series has been repaid. As a result, the impact of significant losses and
shortfalls on the Trust Funds may fall primarily upon those classes of
Certificates having a lower priority of payment. Moreover, if a form of
Enhancement covers more than one Series of Certificates (each, a "Covered
Trust"), holders of Certificates evidencing an interest in a Covered Trust will
be subject to the risk that such Enhancement will be exhausted by the claims of
other Covered Trusts.



                                       7
<PAGE>

         The amount of any applicable Enhancement supporting one or more
classes of Certificates, including the subordination of one or more classes of
other Certificates, will be determined on the basis of criteria established by
each Rating Agency rating such classes of Certificates based on an assumed
level of defaults, delinquencies, other losses or other factors. There can,
however, be no assurance that the loss experience on the related Mortgage Loans
will not exceed such assumed levels.

         Regardless of the form of Enhancement provided, the amount of coverage
will be limited in amount and in most cases will be subject to periodic
reduction in accordance with a schedule or formula. The Master Servicer will
generally be permitted to reduce, terminate or substitute all or a portion of
the Enhancement for any Series of Certificates, if the applicable Rating Agency
indicates that the then-current rating thereof will not be adversely affected.
The rating of any Series of Certificates by any applicable Rating Agency may be
lowered following the initial issuance thereof as a result of the downgrading
of the obligations of any applicable Enhancement provider, or as a result of
losses on the related Mortgage Loans substantially in excess of the levels
contemplated by such Rating Agency at the time of its initial rating analysis.
None of the Depositor, the Master Servicer or any of their affiliates will have
any obligation to replace or supplement any Enhancement, or to take any other
action to maintain any rating of any Series of Certificates.

         Enforceability. Mortgages may contain a due-on-sale clause, which in
general permits the lender to accelerate the maturity of the Mortgage Loan if
the mortgagor sells, transfers or conveys the related Mortgaged Property or its
interest in the Mortgaged Property. Mortgages may also include a
debt-acceleration clause, which permits the lender to accelerate the debt upon
a monetary or non-monetary default by the mortgagor. Such clauses are generally
enforceable subject to certain exceptions. The courts of all states will
enforce clauses providing for acceleration in the event of a material payment
default. The equity courts of any state, however, may refuse the foreclosure of
a mortgage or deed of trust when an acceleration of the indebtedness would be
inequitable or unjust or the circumstances would render the acceleration
unconscionable.

         If so specified in the related Prospectus Supplement, the Mortgage
Loans will be secured by an assignment of leases and rents pursuant to which
the mortgagor typically assigns its right, title and interest as landlord under
the leases on the related Mortgaged Property and the income derived therefrom
to the lender as further security for the related Mortgage Loan, while
retaining a license to collect rents for so long as there is no default. In the
event the mortgagor defaults, the license terminates and the lender is entitled
to collect rents. Such assignments are typically not perfected as security
interests prior to actual possession of the cash flows. Some state laws may
require that the lender take possession of the Mortgaged Property and obtain a
judicial appointment of a receiver before becoming entitled to collect the
rents. In addition, if bankruptcy or similar proceedings are commenced by or in
respect of the mortgagor, the lender's ability to collect the rents may be
adversely affected.

         Environmental Risks. Real property pledged as security for a mortgage
loan may be subject to certain environmental risks. Under the laws of certain
states, contamination of a property may give rise to a lien on the property to
assure the costs of cleanup. In several states, such a lien has priority over
the lien of an existing mortgage against such property. In addition, under the
laws of some states and under the federal Comprehensive Environmental Response,
Compensation and Liability Act of 1980 ("CERCLA") a lender may be liable, as an
"owner" or "operator," for costs of addressing releases or threatened releases
of hazardous substances that require remedy at a property, if agents or
employees of the lender have become sufficiently involved in the operations of
the mortgagor, regardless of whether or not the environmental damage or threat
was caused by a prior owner. A lender also risks such liability on foreclosure
of the mortgage. Each Agreement will provide that the Master Servicer, acting
on behalf of the Trust Fund, may not acquire title to a Mortgaged Property
securing a Mortgage Loan or take over its operation unless such Master Servicer
has previously determined, based upon a report prepared by a 


                                       8
<PAGE>

person who regularly conducts environmental audits, that: (i) the Mortgaged
Property is in compliance with applicable environmental laws or, if not, that
taking such actions as are necessary to bring the Mortgaged Property in
compliance therewith is likely to produce a greater recovery on a present value
basis, after taking into account any risks associated therewith, than not
taking such actions and (ii) there are no circumstances present at the
Mortgaged Property relating to the use, management or disposal of any hazardous
substances for which investigation, testing, monitoring, containment, cleanup
or remediation could be required under any federal, state or local law or
regulation, or that, if any hazardous substances are present for which such
action would be required, taking such actions with respect to the affected
Mortgaged Property is reasonably likely to produce a greater recovery on a
present value basis, after taking into account any risks associated therewith,
than not taking such actions. Any additional restrictions on acquiring title to
a Mortgaged Property may be set forth in the related Prospectus Supplement.

         Delinquent And Non-Performing Mortgage Loans. If so provided in the
related Prospectus Supplement, the Trust Fund for a particular Series of
Certificates may include Mortgage Loans that are past due or are
non-performing. Unless otherwise described in the related Prospectus
Supplement, the servicing of such Mortgage Loans as to which a specified number
of payments are delinquent will be performed by the Special Servicer; however,
the same entity may act as both Master Servicer and Special Servicer.
Enhancement provided with respect to a particular Series of Certificates may
not cover all losses related to such delinquent or nonperforming Mortgage
Loans, and investors should consider the risk that the inclusion of such
Mortgage Loans in the Trust Fund may adversely affect the rate of defaults and
prepayments on the Mortgage Loans in such Trust Fund and the yield on the
Certificates of such Series.

         ERISA Considerations. Generally, ERISA applies to investments made by
employee benefit plans and transactions involving the assets of such plans. Due
to the complexity of regulations which govern such plans, prospective investors
that are subject to ERISA are urged to consult their own counsel regarding
consequences under ERISA of acquisition, ownership and disposition of the
Certificates of any Series.

         Certain Federal Tax Considerations Regarding Residual Interest
Certificates. Holders of Residual Interest Certificates will be required to
report on their federal income tax returns as ordinary income their pro rata
share of the taxable income of the REMIC, regardless of the amount or timing of
their receipt of cash payments, as described in "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES." Accordingly, under certain circumstances, holders of
Certificates that constitute Residual Interest Certificates may have taxable
income and tax liabilities arising from such investment during a taxable year
in excess of the cash received during such period. Individual holders of
Residual Interest Certificates may be limited in their ability to deduct
servicing fees and other expenses of the REMIC. In addition, Residual Interest
Certificates are subject to certain restrictions on transfer. Because of the
special tax treatment of Residual Interest Certificates, the taxable income
arising in a given year on a Residual Interest Certificate will not be equal to
the taxable income associated with investment in a corporate bond or stripped
instrument having similar cash flow characteristics and pre-tax yield.
Therefore, the after-tax yield on the Residual Interest Certificate may be
significantly less than that of a corporate bond or stripped instrument having
similar cash flow characteristics. A Residual Interest Certificate acquired
after January 3, 1995 cannot be marked-to-market.

         Control. Under certain circumstances, the consent or approval of the
holders of a specified percentage of the aggregate Certificate balance of all
outstanding Certificates of a Series or a similar means of allocating
decision-making under the related Agreement ("Voting Rights") will be required
to direct, and will be sufficient to bind all Certificateholders of such Series
to, certain actions, including directing the Special Servicer or the Master
Servicer with respect to actions to be taken with respect to 


                                       9
<PAGE>

certain Mortgage Loans and REO Properties and amending the related Agreement in
certain circumstances.

         Book-Entry Registration. If so provided in the related Prospectus
Supplement, one or more classes of the Certificates will be initially
represented by one or more certificates registered in the name of Cede & Co.,
the nominee for The Depository Trust Company ("DTC"), and will not be
registered in the names of the beneficial owners of such Certificates or their
nominees. Because of this, unless and until definitive certificates are issued,
such beneficial owners will not be recognized by the Trustee as
"Certificateholders" (as that term is to be used in the related Agreement).
Hence, until such time, such beneficial owners will be able to exercise the
rights of Certificateholders only indirectly through DTC and its participating
organizations.

                                 THE DEPOSITOR

         The Depositor was incorporated in the State of Delaware on December
31, 1985, and is a wholly-owned subsidiary of Credit Suisse First Boston
Management Corporation ("CSFBMC"). CSFBMC is a wholly-owned subsidiary of
Credit Suisse First Boston, Inc. Credit Suisse First Boston Corporation, which
may act as an underwriter in offerings made hereby, as described in "PLAN OF
DISTRIBUTION" below, is also a wholly-owned subsidiary of Credit Suisse First
Boston, Inc. The principal executive offices of the Depositor are located at
Eleven Madison Avenue, New York, N.Y. 10010. Its telephone number is (212)
325-2000.

         The Depositor was organized, among other things, for the purposes of
establishing trusts, selling beneficial interests therein and acquiring and
selling mortgage assets to such trusts. Neither the Depositor, its parent nor
any of the Depositor's affiliates will insure or guarantee distributions on the
Certificates of any Series.

         The assets of the Trust Funds will be acquired by the Depositor
directly or through one or more affiliates.

                                USE OF PROCEEDS

         The Depositor will apply all or substantially all of the net proceeds
from the sale of each Series offered hereby and by the related Prospectus
Supplement to purchase the Mortgage Loans relating to such Series, to repay
indebtedness which has been incurred to obtain funds to acquire Mortgage Loans,
to establish the Reserve Funds, if any, for the Series, to obtain other
Enhancement, if any, for the Series and to pay costs of structuring and issuing
the Certificates. If so specified in the related Prospectus Supplement,
Certificates may be exchanged by the Depositor for Mortgage Loans.

                        DESCRIPTION OF THE CERTIFICATES*

         * Whenever in this Prospectus the terms "Certificates," "Trust Fund"
and "Mortgage Pool" are used, such terms will be deemed to apply, unless the
context indicates otherwise, to a specific Series of Certificates, the Trust
Fund underlying the related Series and the related Mortgage Pool.

         The Certificates of each Series will be issued pursuant to a separate
Pooling and Servicing Agreement (the "Agreement") to be entered into among the
Depositor, the Master Servicer and the Trustee for that Series and any other
parties described in the applicable Prospectus Supplement, substantially in the
form filed as an exhibit to the Registration Statement of which this Prospectus
is a part or in such other form as may be described in the applicable
Prospectus Supplement. The following summaries describe certain provisions
expected to be common to each Series and the Agreement with 


                                      10
<PAGE>

respect to the underlying Trust Fund. However, the Prospectus Supplement for
each Series will describe more fully the Certificates and the provisions of the
related Agreement, which may be different from the summaries set forth below.

         At the time of issuance, the Certificates of each Series will be rated
"investment grade," typically one of the four highest generic rating
categories, by at least one nationally recognized statistical rating
organization. Each of such rating organizations specified in the applicable
Prospectus Supplement as rating the Certificates of the related Series is
hereinafter referred to as a "Rating Agency." 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 Agency.

GENERAL

         The Certificates of each Series will be issued in registered or
book-entry form and will represent beneficial ownership interests in the trust
fund (the "Trust Fund") created pursuant to the Agreement for such Series. The
Trust Fund for each Series will comprise, to the extent provided in the
Agreement: (i) the Mortgage Pool, consisting primarily of the Mortgage Loans
conveyed to the Trustee pursuant to the Agreement; (ii) all payments on or
collections in respect of the Mortgage Loans; (iii) all property acquired by
foreclosure or deed in lieu of foreclosure with respect to the Mortgage Loans;
and (iv) such other assets or rights as are described in the related Prospectus
Supplement. In addition, the Trust Fund for a Series may include private
mortgage pass-through certificates, certificates issued or guaranteed by the
Federal Home Loan Mortgage Corporation ("FHLMC"), the Federal National Mortgage
Association ("FNMA") or the Governmental National Mortgage Association ("GNMA")
or mortgage pas through certificates previously created by the Depositor, as
well as various forms of Enhancement, such as, but not limited to, insurance
policies on the Mortgage Loans, letters of credit, certificate guarantee
insurance policies, the right to make draws upon one or more Reserve Funds or
other arrangements acceptable to each Rating Agency rating the Certificates.
See "ENHANCEMENT." Such other assets will be described more fully in the
related Prospectus Supplement.

         If so specified in the applicable Prospectus Supplement, Certificates
of a given Series may be issued in several Classes which may pay interest at
different rates, may represent different allocations of the right to receive
principal and interest payments, and certain of which may be subordinated to
other Classes in the event of shortfalls in available cash flow from the
underlying Mortgage Loans. Alternatively, or in addition, Classes may be
"time-tranched" and, therefore, structured to receive principal payments in
sequence. Each Class in a group of "time-tranched" Classes would be entitled to
be paid in full before the next Class in the group is entitled to receive any
principal payments. A Class of Certificates may also provide for payments of
principal only or interest only or for disproportionate payments of principal
and interest. Subordinate Certificates of a given Series of Certificates may be
offered in the same Prospectus Supplement as the Senior Certificates of such
Series or may be offered in a separate Prospectus Supplement. Each Class of
Certificates of a Series will be issued in the minimum denominations specified
in the related Prospectus Supplement.

         The Prospectus Supplement for any Series including Classes similar to
any of those described above will contain a complete description of their
characteristics and risk factors, including, as applicable, (i) mortgage
principal prepayment effects on the weighted average lives of Classes, (ii) the
risk that interest only, or disproportionately interest weighted, Classes
purchased at a premium may not return their purchase prices under rapid
prepayment scenarios and (iii) the degree to which an investor's yield is
sensitive to principal prepayments.

         The Certificates of each Series will be freely transferable and
exchangeable at the office specified in the related Agreement and Prospectus
Supplement, provided, however, that certain Classes of 


                                      11
<PAGE>

Certificates may be subject to transfer restrictions described in the related
Prospectus Supplement. If specified in the related Prospectus Supplement, the
Certificates may be transferable only on the books of The Depository Trust
Company or another depository identified in such Prospectus Supplement.

DISTRIBUTIONS ON CERTIFICATES

         Distributions of principal and interest on the Certificates of each
Series will be made to the registered holders thereof ("Certificateholders" or
"Holders") by the Trustee (or such other paying agent as may be identified in
the related Prospectus Supplement) on the day (the "Distribution Date")
specified in the related Prospectus Supplement, beginning in the period
specified in the related Prospectus Supplement following the establishment of
the related Trust Fund. Distributions for each Series will be made by check
mailed to the address of the person entitled thereto as it appears on the
certificate register for such Series maintained by the Trustee, by wire
transfer or by such other method as is specified in the related Prospectus
Supplement. Unless otherwise specified in the applicable Prospectus Supplement,
the final distribution in retirement of the Certificates of each Series will be
made only upon presentation and surrender of the Certificates at the office or
agency specified in the notice to the Certificateholders of such final
distribution. In addition, the Prospectus Supplement relating to each Series
will set forth the applicable due period, prepayment period, record date,
Cut-Off Date and determination date in respect of each Series of Certificates.

         With respect to each Series of Certificates on each Distribution Date,
the Trustee (or such other paying agent as may be identified in the applicable
Prospectus Supplement) will distribute to the Certificateholders the amounts
described in the related Prospectus Supplement that are due to be paid on such
Distribution Date. In general, such amounts will include previously
undistributed payments of principal (including principal prepayments, if any)
and interest on the Mortgage Loans received by the Trustee after a date
specified in the related Prospectus Supplement (the "Cut-Off Date") and prior
to the day preceding each Distribution Date specified in the related Prospectus
Supplement.

ACCOUNTS

         It is expected that the Agreement for each Series of Certificates will
provide that the Trustee establish an account (the "Distribution Account") into
which the Master Servicer will deposit amounts held in the Collection Account
from which account distributions will be made with respect to a given
Distribution Date. On each Distribution Date, the Trustee will apply amounts on
deposit in the Distribution Account generally to make distributions of interest
and principal to the Certificateholders in the manner described in the related
Prospectus Supplement.

         It is also expected that the Agreement for each Series of Certificates
will provide that the Master Servicer establish and maintain a special trust
account (the "Collection Account") in the name of the Trustee for the benefit
of Certificateholders. Unless otherwise specified in the related Prospectus
Supplement, the Master Servicer will deposit into the Collection Account, as
more fully described in the related Prospectus Supplement: (1) all payments on
account of principal, including principal prepayments, on the Mortgage Loans;
(2) all payments on account of interest on the Mortgage Loans and all
Prepayment Premiums; (3) all proceeds from any insurance policy relating to a
Mortgage Loan ("Insurance Proceeds") other than proceeds applied to restoration
of the related Mortgaged Property; (4) all proceeds from the liquidation of a
Mortgage Loan ("Liquidation Proceeds"), including the sale of any Mortgaged
Property acquired on behalf of the Trust Fund through foreclosure or deed in
lieu of foreclosure ("REO Property"); (5) all proceeds received in connection
with the taking of a Mortgaged Property by eminent domain; (6) any amounts
required to be deposited by the Master Servicer to cover net losses on
Permitted Investments made with funds held in the Collection Account; (7) any
amounts required to be deposited in connection with the application of
co-insurance clauses, flood damage to REO 


                                      12
<PAGE>

Properties and blanket policy deductibles; (8) any amounts required to be
deposited from income with respect to any REO Property; and (9) any amounts
received from Borrowers which represent recoveries of Property Protection
Expenses. "Prepayment Premium" means any premium paid or payable by the related
Borrower in connection with any principal prepayment on any Mortgage Loan.
"Property Protection Expenses" comprise certain costs and expenses incurred in
connection with defaulted Mortgage Loans, acquiring title or management of REO
Property or the sale of defaulted Mortgage Loans or REO Properties, as more
fully described in the related Agreement. As set forth in the Agreement for
each Series, the Master Servicer will be entitled to make certain withdrawals
from the Collection Account to, among other things: (i) remit certain amounts
for the related Distribution Date into the Distribution Account; (ii) reimburse
Property Protection Expenses and pay taxes, assessments and insurance premiums
and certain third-party expenses in accordance with the Agreement; (iii) pay
accrued and unpaid servicing fees to the Master Servicer out of all Mortgage
Loan collections; and (iv) reimburse the Master Servicer, the Trustee and the
Depositor for certain expenses and provide indemnification to the Depositor and
the Master Servicer as described in the Agreement.

         The amount at any time credited to the Collection Account may be
invested in Permitted Investments that are payable on demand or in general
mature or are subject to withdrawal or redemption on or before the business day
preceding the next succeeding Master Servicer Remittance Date. The Master
Servicer will be required to remit amounts required for distribution to
Certificateholders to the Distribution Account on the business day preceding
the related Distribution Date (the "Master Servicer Remittance Date"). The
income from the investment of funds in the Collection Account in Permitted
Investments will constitute additional servicing compensation for the Master
Servicer, and the risk of loss of funds in the Collection Account resulting
from such investments will be borne by the Master Servicer. The amount of each
such loss will be required to be deposited by the Master Servicer in the
Collection Account immediately as realized.

         It is expected that the Agreement for each Series of Certificates will
provide that a special trust account (the "REO Account") will be established
and maintained in order to be used in connection with REO Properties and, if
specified in the related Prospectus Supplement, certain other Mortgaged
Properties. To the extent set forth in the Agreement, certain withdrawals from
the REO Account will be made to, among other things, (i) make remittances to
the Collection Account as required by the Agreement, (ii) pay taxes,
assessments, insurance premiums, other amounts necessary for the proper
operation, management and maintenance of the REO Properties and such Mortgaged
Properties and certain third-party expenses in accordance with the Agreement
and (iii) provide for the reimbursement of certain expenses in respect of the
REO Properties and such Mortgaged Properties.

         The amount at any time credited to the REO Account will be fully
insured to the maximum coverage possible or will be invested in Permitted
Investments that mature, or are subject to withdrawal or redemption, on or
before the business day on which such amounts are required to be remitted to
the Master Servicer for deposit in the Collection Account. The income from the
investment of funds in the REO Account in Permitted Investments shall be
deposited in the REO Account for remittance to the Collection Account, and the
risk of loss of funds in the REO Account resulting from such investments will
be borne by the Trust Fund.

         Unless otherwise specified in the applicable Prospectus Supplement,
"Permitted Investments" will consist of one or more of the following:

         (i) direct obligations of, or guarantees as to timely payment of
principal and interest by, the United States or any agency or instrumentality
thereof provided that such obligations are backed by the full faith and credit
of the United States of America;



                                      13
<PAGE>

         (ii) direct obligations of, or guarantees as to timely payment of
principal and interest by, the FHLMC, FNMA or the Federal Farm Credit System,
provided that any such obligation, at the time of purchase of such obligation
or contractual commitment providing for the purchase thereof, is qualified by
each Rating Agency as an investment of funds backing securities having ratings
equivalent to each Rating Agency's highest initial rating of the Certificates;

         (iii) demand and time deposits in or certificates of deposit of, or
bankers' acceptances issued by, any bank or trust company, savings and loan
association or savings bank, provided that, in the case of obligations that are
not fully FDIC-insured deposits, the commercial paper and/or long-term
unsecured debt obligations of such depository institution or trust company (or
in the case of the principal depository institution in a holding company
system, the commercial paper or long-term unsecured debt obligations of such
holding company) have the highest rating available for such securities by each
Rating Agency (in the case of commercial paper) or have received one of the two
highest ratings available for such securities by each Rating Agency (in the
case of long-term unsecured debt obligations), or such lower rating as will not
result in the downgrade or withdrawal of the rating or ratings then assigned to
the Certificates by any Rating Agency;

         (iv) general obligations of or obligations guaranteed by any state of
the United States or the District of Columbia receiving one of the two highest
long-term debt ratings available for such securities by each Rating Agency, or
such lower rating as will not result in the downgrading or withdrawal of the
rating or ratings then assigned to the Certificates by any such Rating Agency;

         (v) commercial or finance company paper (including both
non-interest-bearing discount obligations and interest-bearing obligations
payable on demand or on a specified date not more than one year after the date
of issuance thereof) that is rated by each Rating Agency in its highest
short-term unsecured rating category at the time of such investment or
contractual commitment providing for such investment, and is issued by a
corporation the outstanding senior long-term debt obligations of which are then
rated by each Rating Agency in one of its two highest long-term unsecured
rating categories, or such lower rating as will not result in the downgrading
or withdrawal of the rating or ratings then assigned to the Certificates by any
Rating Agency;

         (vi) guaranteed reinvestment agreements issued by any bank, insurance
company or other corporation rated in one of the two highest ratings available
to such issuers by each Rating Agency at the time of such investment provided
that any such agreement must by its terms provide that it is terminable by the
purchaser without penalty in the event any such rating is at any time lower
than such level;

         (vii) repurchase obligations with respect to any security described in
clause (i) or (ii) above entered into with a depository institution or trust
company (acting as principal) meeting the ratings standard described in (iii)
above;

         (viii) securities bearing interest or sold at a discount issued by any
corporation incorporated under the laws of the United States or any state
thereof and rated by each Rating Agency in one of its two highest long-term
unsecured rating categories at the time of such investment or contractual
commitment providing therefor; provided, however, that securities issued by any
such corporation will not be Permitted Investments to the extent that
investment therein would cause the then outstanding principal amount of
securities issued by such corporation and held as part of the Collection
Account or the Distribution Account to exceed 20% of the aggregate principal
amount of all Permitted Investments held in the Collection Account and the
Distribution Account;

         (ix) units of taxable money market funds which funds are regulated
investment companies, seek to maintain a constant net asset value per share and
invest solely in obligations backed by the full 


                                      14
<PAGE>

faith and credit of the United States, and have been designated in writing by 
each Rating Agency as Permitted Investments with respect to this definition;

         (x) if previously confirmed in writing to the Trustee, any other
demand, money market or time deposit, or any other obligation, security or
investment, as may be acceptable to each Rating Agency as an investment of
funds backing securities having ratings equivalent to each Rating Agency's
highest initial rating of the Certificates; and

         (xi) such other obligations as are acceptable as Permitted Investments
to each Rating Agency; provided, however, that (a) such instrument or security
shall qualify as a "cash flow investment" pursuant to the Internal Revenue Code
of 1986, as amended (the "Code") and (b) no instrument or security shall be a
Permitted Investment if (i) such instrument or security evidences a right to
receive only interest payments or (ii) the stated interest rate on such
investment is in excess of 120% of the yield to maturity produced by the price
at which such investment was purchased.

AMENDMENT

         The Agreement for each Series will provide that it may be amended by
the parties thereto without the consent of any of the Certificateholders to
cure any ambiguity, to correct or supplement any provision therein that may be
inconsistent with any other provision therein, to maintain the rating or
ratings assigned to the Certificates by a Rating Agency or to make other
provisions with respect to matters or questions arising under the Agreement
which are not inconsistent with the provisions of the Agreement, provided that
such action will not, as evidenced by an opinion of counsel acceptable to the
Depositor and the Trustee, adversely affect in any material respect the
interests of any Certificateholder.

         Each Agreement will also provide that it may be amended by the parties
thereto with the consent of the Holders of Certificates representing an
aggregate outstanding principal amount of not less than a percentage specified
in the related Agreement of each Class of Certificates affected by the proposed
amendment for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Agreement or modifying in any
manner the rights of Certificateholders; provided, however, that no such
amendment may (i) reduce in any manner the amount of, or delay the timing of,
payments received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of each affected Certificateholder, (ii) reduce
the aforesaid percentage of Certificates the Holders of which are required to
consent to any such amendment, without the consent of the Holders of all
Certificates then outstanding, or (iii) alter the servicing standard set forth
in the Agreement. Further, the Agreement for each Series may provide that the
parties thereto, at any time and from time to time, without the consent of the
Certificateholders, may amend the Agreement to modify, eliminate or add to any
of its provisions to such extent as shall be necessary to maintain the
qualification of the REMIC Pool as a REMIC at all times that any of the
Certificates are outstanding; provided, however, that such action, as evidenced
by an opinion of counsel acceptable to the Trustee, is necessary or helpful to
maintain such qualification, and would not adversely affect in any material
respect the interest of any Certificateholder.

         The Agreement relating to each Series may provide that no amendment to
such Agreement will be made unless there has been delivered in accordance with
such Agreement an opinion of counsel to the effect that such amendment will not
cause such Series to fail to qualify as a REMIC at any time that any of the
Certificates are outstanding.

         The Prospectus Supplement for a Series may describe other or different
provisions concerning the amendment of the related Agreement.

TERMINATION; REPURCHASE OF MORTGAGE LOANS

         The obligations of the parties to the Agreement for each Series will
terminate upon: (i) the purchase of all of the assets of the related Trust
Fund, as described in the related Prospectus Supplement; (ii) the later of (a)
the distribution to Certificateholders of that Series of final payment with
respect to the last outstanding Mortgage Loan or (b) the disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure with respect
to the last outstanding Mortgage Loan and the remittance to the
Certificateholders of all funds due under the Agreement; (iii) the sale of the
assets of the related Trust Fund after the principal amounts of all
Certificates have been reduced to zero under circumstances set forth in the
Agreement; or (iv) mutual consent of the parties and all Certificateholders.
With respect to each Series, the Trustee will give or cause to be given written
notice of termination of the Agreement to each Certificateholder and, unless
otherwise specified in the applicable Prospectus Supplement, the final
distribution under the Agreement will be made only upon surrender and
cancellation of the related Certificates at an office or agency specified in
the notice of termination.

REPORTS TO CERTIFICATEHOLDERS

         Concurrently with each distribution for each Series, the Trustee (or
such other paying agent as may be identified in the applicable Prospectus
Supplement) will forward to each Certificateholder a statement setting forth
such information relating to such distribution as is specified in the Agreement
and described in the applicable Prospectus Supplement.

The Trustee

         The Depositor will select a bank or trust company to act as trustee
(the "Trustee") under the Agreement for each Series and the Trustee will be
identified, and its obligations under that Agreement will be described, in the
applicable Prospectus Supplement.

                               THE MORTGAGE POOLS

GENERAL

         Each Mortgage Pool will consist of mortgage loans secured by first or
junior mortgages, deeds of trust or similar security instruments ("Mortgages")
on, or installment contracts ("Installment Contracts") for the sale of, fee
simple or leasehold interests in commercial real estate property, multifamily
residential property, cooperatively owned multifamily properties and/or mixed
residential/commercial property and related property and interests (each such
interest or property, as the case may be, a "Mortgaged Property") located,
unless otherwise specified in the related Prospectus Supplement, in any one of
the fifty states, the District of Columbia or the Commonwealth of Puerto Rico.
A Mortgage Pool may also include any or all of the participation interests in
such types of mortgage loans, private mortgage pass-through certificates,
certificates issued or guaranteed by FHLMC, FNMA or GNMA and mortgage
pass-through certificates previously created by the Depositor. Each such
mortgage loan, Installment Contract, participation interest or certificate is
herein referred to as a "Mortgage Loan."

         All Mortgage Loans will be of one or more of the following types:

         1. mortgage loans with fixed interest rates;

         2. mortgage loans with adjustable interest rates;



                                      16
<PAGE>

         3. mortgage loans whose principal balances fully amortize over their
remaining terms to maturity;

         4. mortgage loans whose principal balances do not fully amortize but
instead provide for a substantial principal payment at the stated maturity of
the loan;

         5. mortgage loans that provide for recourse against only the Mortgaged
Properties;

         6. mortgage loans that provide for recourse against the other assets
of the related Borrowers (as defined below); and

         7. any other types of mortgage loans described in the applicable
Prospectus Supplement.

         Certain Mortgage Loans ("Simple Interest Loans") may provide that
scheduled interest and principal payments thereon are applied first to interest
accrued from the last date to which interest has been paid to the date such
payment is received and the balance thereof is applied to principal, and other
Mortgage Loans may provide for payment of interest in advance rather than in
arrears.

         Mortgage Loans may also be secured by one or more assignments of
leases and rents, management agreements or operating agreements relating to the
Mortgaged Property and in some cases by certain letters of credit, personal
guarantees or both. Pursuant to an assignment of leases and rents, the obligor
(the "Borrower") on the related promissory note (the "Note") assigns its right,
title and interest as landlord under each lease and the income derived
therefrom to the related lender, while retaining a license to collect the rents
for so long as there is no default. If the Borrower defaults, the license
terminates and the related lender is entitled to collect the rents from tenants
to be applied to the monetary obligations of the Borrower. State law may limit
or restrict the enforcement of the assignment of leases and rents by a lender
until the lender takes possession of the related Mortgaged Property and a
receiver is appointed. See "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
- --Leases and Rents.

         A Trust Fund may consist of a single Mortgage Loan or a number of
Mortgage Loans with a single obligor or related obligors thereunder, or
multiple Mortgage Loans with multiple unrelated obligors thereunder, as
specified in the related Prospectus Supplement. The Mortgage Loans will be
newly originated or seasoned, and will be acquired by the Depositor either
directly or through one or more affiliates.

         Unless otherwise specified in the Prospectus Supplement for a Series,
the Mortgage Loans will not be insured or guaranteed by the United States, any
governmental agency, any private mortgage insurer or any other person or
entity.

         The Prospectus Supplement relating to each Series will specify the
originator or originators relating to the Mortgage Loans, which may include,
among others, commercial banks, savings and loan associations, other financial
institutions, insurance companies or real estate developers, and the
underwriting criteria to the extent available in connection with originating
the Mortgage Loans. The criteria applied by the Depositor in selecting the
Mortgage Loans to be included in a Mortgage Pool will vary from Series to
Series. The Prospectus Supplement relating to each Series also will provide
specific information regarding the characteristics of the Mortgage Loans, as of
the Cut-Off Date, including, among other things: (i) the aggregate principal
balance of the Mortgage Loans; (ii) the types of properties securing the
Mortgage Loans and the aggregate principal balance of the Mortgage Loans
secured by each type of property; (iii) the interest rate or range of interest
rates of the Mortgage Loans; (iv) the origination dates and the original and,
with respect to seasoned Mortgage Loans, remaining terms to stated maturity of
the Mortgage Loans; (v) the loan-to-value ratios at origination and, with
respect to seasoned Mortgage Loans, current loan balance-to-original value
ratios of the Mortgage Loans; (vi) the geographic 


                                      17
<PAGE>

distribution of the Mortgaged Properties underlying the Mortgage Loans; (vii)
the minimum interest rates, margins, adjustment caps, adjustment frequencies,
indices and other similar information applicable to adjustable rate Mortgage
Loans; (viii) the debt service coverage ratios relating to the Mortgage Loans;
and (ix) payment delinquencies, if any, relating to the Mortgage Loans. The
applicable Prospectus Supplement will also specify any inadequate, incomplete
or obsolete documentation relating to the Mortgage Loans and other
characteristics of the Mortgage Loans relating to each Series. If specified in
the applicable Prospectus Supplement, the Depositor may segregate the Mortgage
Loans in a Mortgage Pool into separate "Mortgage Loan Groups" (as described in
the related Prospectus Supplement) as part of the structure of the payments of
principal and interest on the Certificates of a Series. In such case, the
Depositor will disclose the above-specified information by Mortgage Loan Group.

         The Depositor will file a current report on Form 8-K (the "Form 8-K")
with the Securities and Exchange Commission within 15 days after the initial
issuance of each Series of Certificates (each, a "Closing Date"), as specified
in the related Prospectus Supplement, which will set forth information with
respect to the Mortgage Loans included in the Trust Fund for a Series as of the
related Closing Date. The Form 8-K will be available to the Certificateholders
of the related Series promptly after its filing.

ASSIGNMENT OF MORTGAGE LOANS

         At the time of issuance of the Certificates of each Series, the
Depositor will cause the Mortgage Loans to be assigned to the Trustee, together
with, as more fully specified in the related Prospectus Supplement, all
principal and interest due on or with respect to such Mortgage Loans, other
than principal and interest due on or before the Cut-Off Date and principal
prepayments received on or before the Cut-Off Date. The Trustee, concurrently
with such assignment, will execute and deliver Certificates evidencing the
beneficial ownership interests in the related Trust Fund to the Depositor in
exchange for the Mortgage Loans. Each Mortgage Loan will be identified in a
schedule appearing as an exhibit to the Agreement for the related Series (the
"Mortgage Loan Schedule"). The Mortgage Loan Schedule will include, among other
things, as to each Mortgage Loan, information as to its outstanding principal
balance as of the close of business on the Cut-Off Date, as well as information
respecting the interest rate, the scheduled monthly (or other periodic) payment
of principal and interest as of the Cut-Off Date and the maturity date of each
Note.

         In addition, except to the extent otherwise specified in the
applicable Prospectus Supplement, the Depositor will, as to each Mortgage Loan,
deliver to the Trustee: (i) the Note, endorsed to the order of the Trustee
without recourse; (ii) the Mortgage and an executed assignment thereof in favor
of the Trustee or otherwise as required by the Agreement; (iii) any assumption,
modification or substitution agreements relating to the Mortgage Loan; (iv) a
lender's title insurance policy (or owner's policy in the case of an
Installment Contract), together with its endorsements, or an attorney's opinion
of title issued as of the date of origination of the Mortgage Loan; (v) if the
assignment of leases, rents and profits is separate from the Mortgage, an
executed re-assignment of assignment of leases, rents and profits to the
Trustee; and (vi) such other documents as may be described in the Agreement
(such documents collectively, the "Mortgage Loan File"). Unless otherwise
expressly permitted by the Agreement, all documents included in the Mortgage
Loan File are to be original executed documents; provided, however, that in
instances where the original recorded Mortgage, Mortgage assignment or any
document necessary to assign the Depositor's interest in Installment Contracts
to the Trustee, as described in the Agreement, has been retained by the
applicable jurisdiction or has not yet been returned from recordation, the
Depositor may deliver a photocopy thereof certified to be the true and complete
copy of the original thereof submitted for recording.

         The Trustee will hold the Mortgage Loan File for each Mortgage Loan in
trust for the benefit of all Certificateholders. Pursuant to the Agreement, the
Trustee is obligated to review the Mortgage Loan 


                                      18
<PAGE>

File for each Mortgage Loan within a specified number of days after the
execution and delivery of the Agreement. Unless otherwise specified in the
related Prospectus Supplement, if any document in the Mortgage Loan File is
found to be defective in any material respect, the Trustee will promptly notify
the Depositor and the Master Servicer. Unless otherwise specified in the
related Prospectus Supplement, if the Master Servicer or other entity cannot
cure such defect within the time period specified in such Prospectus
Supplement, the Master Servicer or such other entity will be obligated to
either substitute the affected Mortgage Loan for a Substitute Mortgage Loan or
Loans, or to repurchase the related Mortgage Loan from the Trustee within the
time period specified in such Prospectus Supplement at a price equal to the
principal balance thereof as of the date of purchase or, in the case of a
Series as to which an election has been made to treat the related Trust Fund as
a REMIC, at such other price as may be necessary to avoid a tax on a prohibited
transaction, as described in Section 860F(a) of the Code, in each case together
with accrued interest at the applicable Pass-Through Rate to the first day of
the month following such repurchase, plus the amount of any unreimbursed
advances made by the Master Servicer in respect of such Mortgage Loan. Unless
otherwise specified in the applicable Prospectus Supplement, this purchase
obligation constitutes the sole remedy available to the Holders of Certificates
or the Trustee for a material defect in a constituent document.

MORTGAGE UNDERWRITING STANDARDS AND PROCEDURES

         The underwriting procedures and standards for Mortgage Loans included
in a Mortgage Pool will be specified in the related Prospectus Supplement to
the extent such procedures and standards are known or available. Such Mortgage
Loans may be originated in contemplation of the transactions contemplated by
this Prospectus and the related Prospectus Supplement or may have been
originated by third-parties and acquired by the Depositor directly or through
its affiliates in negotiated transactions.

         Except as otherwise set forth in the related Prospectus Supplement for
a Series, the originator of a Mortgage Loan will have applied underwriting
procedures intended to evaluate, among other things, the income derived from
the Mortgaged Property, the capabilities of the management of the project,
including a review of management's past performance record, its management
reporting and control procedures (to determine its ability to recognize and
respond to problems) and its accounting procedures (to determine cash
management ability, the obligor's credit standing and repayment ability and the
value and adequacy of the Mortgaged Property as collateral). Mortgage Loans
insured by the Federal Housing Administration ("FHA"), a division of the United
States Department of Housing and Urban Development ("HUD"), will have been
originated by mortgage lenders which are approved by HUD as an FHA mortgagee in
the ordinary course of their real estate lending activities and will comply
with the underwriting policies of FHA.

         If so specified in the related Prospectus Supplement, the adequacy of
a Mortgaged Property as security for repayment will generally have been
determined by appraisal by appraisers selected in accordance with
preestablished guidelines established by or acceptable to the loan originator
for appraisers. If so specified in the related Prospectus Supplement, the
appraiser must have personally inspected the property and verified that it was
in good condition and that construction, if new, has been completed. Unless
otherwise stated in the applicable Prospectus Supplement, the appraisal will
have been based upon a cash flow analysis and/or a market data analysis of
recent sales of comparable properties and, when deemed applicable, a
replacement cost analysis based on the current cost of constructing or
purchasing a similar property.

         No assurance can be given that values of the Mortgaged Properties have
remained or will remain at their levels on the dates of origination of the
related Mortgage Loans. Further, there is no assurance that appreciation of
real estate values generally will limit loss experiences on commercial
properties or multifamily residential properties. If the commercial real estate
market should experience an overall 


                                      19
<PAGE>

decline in property values such that the outstanding balances of the Mortgage
Loans and any additional financing on the Mortgaged Properties in a particular
Mortgage Pool become equal to or greater than the value of the Mortgaged
Properties, the actual rates of delinquencies, foreclosures and losses could be
higher than those now generally experienced in the mortgage lending industry.
To the extent that such losses are not covered by the methods of Enhancement or
the insurance policies described herein, the ability of the Depositor to pay
principal of and interest on the Certificates may be adversely affected. Even
where credit support covers all losses resulting from defaults and foreclosure,
the effect of defaults and foreclosures may be to increase prepayment
experience on the Mortgage Loans, thus shortening weighted average life and
affecting yield to maturity.

REPRESENTATIONS AND WARRANTIES

         Unless otherwise specified in the related Prospectus Supplement, the
seller (the "Unaffiliated Seller") of a Mortgage Loan to the Depositor or any
of its affiliates (or the Master Servicer, if the Unaffiliated Seller is also
the Master Servicer under the Agreement) will have made representations and
warranties in respect of the Mortgage Loans sold by such Unaffiliated Seller
(or the Master Servicer) to the Depositor or its affiliates. Such
representations and warranties will generally include, among other things: (i)
with respect to each Mortgaged Property, that title insurance (or in the case
of Mortgaged Properties located in areas where such policies are generally not
available, an attorney's opinion of title) and any required hazard insurance
was effective at the origination of each Mortgage Loan, and that each policy
(or opinion of title) remained in effect on the date of purchase of the
Mortgage Loan from the Unaffiliated Seller; (ii) that the Unaffiliated Seller
had good and marketable title to each such Mortgage Loan; (iii) with respect to
each Mortgaged Property, that each mortgage constituted a valid first lien on
the Mortgaged Property (subject only to permissible title insurance
exceptions), unless otherwise specified in the related Prospectus Supplement;
(iv) that there were no delinquent tax or assessment liens against the
Mortgaged Property; and (v) that each Mortgage Loan was current as to all
required payments (unless otherwise specified in the related Prospectus
Supplement).

         All of the representations and warranties of an Unaffiliated Seller in
respect of a Mortgage Loan will have been made as of the date on which such
Unaffiliated Seller sold the Mortgage Loan to the Depositor or its affiliate. A
substantial period of time may have elapsed between such date and the date of
the initial issuance of the Series of Certificates evidencing an interest in
such Mortgage Loan. Since the representations and warranties of an Unaffiliated
Seller do not address events that may occur following the sale of a Mortgage
Loan by an Unaffiliated Seller, the repurchase obligation of the Unaffiliated
Seller described below will not arise if, on or after the date of the sale of a
Mortgage Loan by the Unaffiliated Seller to the Depositor or its affiliates,
the relevant event occurs that would have given rise to such an obligation.
However, the Depositor will not include any Mortgage Loan in the Trust Fund for
any Series of Certificates if anything has come to the Depositor's attention
that would cause it to believe that the representations and warranties of an
Unaffiliated Seller will not be accurate and complete in all material respects
in respect of such Mortgage Loan as of the related Cut-Off Date. If so
specified in the related Prospectus Supplement, the Depositor will make certain
representations and warranties for the benefit of Holders of Certificates of a
Series in respect of a Mortgage Loan that relate to the period commencing on
the date of sale of such Mortgage Loan to the Depositor or its affiliates.

         Unless otherwise set forth or specified in the related Prospectus
Supplement, upon the discovery of the breach of any representation or warranty
made by an Unaffiliated Seller in respect of a Mortgage Loan that materially
and adversely affects the interests of the Certificateholders of the related
Series, such Unaffiliated Seller or, if so specified in the related Prospectus
Supplement, the Master Servicer will be obligated to repurchase such Mortgage
Loan at a purchase price equal to 100% of the unpaid principal balance thereof
at the date of repurchase or, in the case of a Series of Certificates as to
which the Depositor has elected to treat the related Trust Fund as a REMIC, as
defined in the Code, at such other 


                                      20
<PAGE>

price as may be necessary to avoid a tax on a prohibited transaction, as
described in Section 860F(a) of the Code, in each case together with accrued
interest at the Pass-Through Rate for the related Mortgage Pool, to the first
day of the month following such repurchase and the amount of any unreimbursed
advances made by the Master Servicer in respect of such Mortgage Loan. The
Master Servicer will be required to enforce such obligation of the Unaffiliated
Seller for the benefit of the Trustee and the Certificateholders, following the
practices it would employ in its good faith business judgment were it the owner
of such Mortgage Loan. Unless otherwise specified in the applicable Prospectus
Supplement and subject to the ability of the Unaffiliated Seller or the Master
Servicer to deliver Substitute Mortgage Loans for certain Mortgage Loans as
described below, this repurchase obligation constitutes the sole remedy
available to the Certificateholders of such Series for a breach of a
representation or warranty by an Unaffiliated Seller.

         Any obligation of the Master Servicer to purchase a Mortgage Loan if
an Unaffiliated Seller defaults on its obligation to do so is subject to
limitations, and no assurance can be given that an Unaffiliated Seller will
carry out its repurchase obligation with respect to the Mortgage Loans.

         The Depositor will make representations and warranties with respect to
the Mortgage Loans in a Mortgage Pool, as specified in the related Prospectus
Supplement. Upon a breach of any representation or warranty by the Depositor
that materially and adversely affects the interests of the Certificateholders,
the Depositor will be obligated either to cure the breach in all material
respects or to purchase the related Mortgage Loan at the purchase price set
forth above. Unless otherwise specified in the applicable Prospectus Supplement
and subject to the ability of the Depositor to deliver Substitute Mortgage
Loans for certain Mortgage Loans as described below, this repurchase obligation
constitutes the sole remedy available to the Certificateholders or the Trustee
for a breach of representation or warranty by the Depositor.

         The proceeds of any repurchase of a Mortgage Loan will be deposited,
subject to certain limitations set forth in the related Agreement, into the
Collection Account.

         Within the period of time specified in the related Prospectus
Supplement, following the date of issuance of a Series of Certificates, the
Depositor, the Master Servicer or the Unaffiliated Seller, as the case may be,
may deliver to the Trustee Mortgage Loans ("Substitute Mortgage Loans") in
substitution for any one or more of the Mortgage Loans ("Deleted Mortgage
Loans") initially included in the Trust Fund but which do not conform in one or
more respects to the description thereof contained in the related Prospectus
Supplement, as to which a breach of a representation or warranty is discovered,
which breach materially and adversely affects the interests of the
Certificateholders, or as to which a document in the related Mortgage Loan File
is defective in any material respect. Unless otherwise specified in the related
Prospectus Supplement, the required characteristics of any Substitute Mortgage
Loan will generally include, among other things, that such Substitute Mortgage
Loan on the date of substitution, will (i) have an outstanding principal
balance, after deduction of all scheduled payments due in the month of
substitution, not in excess of the outstanding principal balance of the Deleted
Mortgage Loan (the amount of any shortfall to be distributed to
Certificateholders in the month of substitution), (ii) have a per annum
interest rate (the "Mortgage Interest Rate") not less than (and not more than
1% greater than) the Mortgage Interest Rate of the Deleted Mortgage Loan, (iii)
have a remaining term to maturity not greater than (and not more than one year
less than) that of the Deleted Mortgage Loan and (iv) comply with all the
representations and warranties set forth in the Agreement as of the date of
substitution.

                        SERVICING OF THE MORTGAGE LOANS

GENERAL

         The Prospectus Supplement related to a Series will identify the master
servicer, or if there is only one servicer of the Mortgage Loans, the servicer
thereof (as applicable, the "Master Servicer") and will set forth certain
information concerning the Master Servicer. The Master Servicer may be an
affiliate of the Depositor and may have other business relationships with the
Depositor and its affiliates.

         The Master Servicer will be responsible for servicing the Mortgage
Loans pursuant to the Agreement for the related Series. If so specified in the
related Prospectus Supplement, the Master Servicer may subcontract the
servicing of all or a portion of the Mortgage Loans to one or more
sub-servicers and may subcontract the servicing of certain Mortgage Loans that
are in default or otherwise require special servicing (the "Specially Serviced
Mortgage Loans") to a special servicer (the "Special Servicer"), and certain
information with respect to the Special Servicer will be set forth in such
Prospectus Supplement. Such sub-servicers and the Special Servicer may be an
affiliate of the Depositor and may have other business relationships with
Depositor and its affiliates.

COLLECTIONS AND OTHER SERVICING PROCEDURES

         The Master Servicer will make reasonable efforts to collect all
payments called for under the Mortgage Loans and will, consistent with the
related Agreement, following such collection procedures as it deems necessary
or desirable. Consistent with the above, the Master Servicer may, in its
discretion, waive any late payment or assumption charge or penalty interests in
connection with late payment or assumption of a Mortgage Loan and, if so
specified in the related Prospectus Supplement, may extend the due dates for
payments due on a Note.

         It is expected that the Agreement for each Series will provide that
the Master Servicer establish and maintain an escrow account (the "Escrow
Account") in which the Master Servicer will be required to deposit amounts
received from each Borrower, if required by the terms of the related Note, for
the payment of taxes, assessments, certain mortgage and hazard insurance
premiums and other comparable items. The Special Servicer, if any, will be
required to remit amounts received for such purposes on Mortgage Loans serviced
by it for deposit in the Escrow Account, and will be entitled to direct the
Master Servicer to make withdrawals from the Escrow Account as may be required
for servicing of such Mortgage Loans. Withdrawals from the Escrow Account may
be made to effect timely payment of taxes, assessments, mortgage and hazard
insurance premiums, to refund to Borrowers amounts determined to be overages,
to remove amounts deposited therein in error, to pay interest to Borrowers on
balances in the Escrow Account, if required, to repair or otherwise protect the
Mortgaged Properties and to clear and terminate such account. The Master
Servicer will be entitled to all income on the funds in the Escrow Account
invested in Permitted Investments not required to be paid to Borrowers under
applicable law. The Master Servicer will be responsible for the administration
of the Escrow Account. If amounts on deposit in the Escrow Account are
insufficient to pay any tax, insurance premium or other similar item when due,
such item will be payable from amounts on deposit in the Collection Account or,
to the extent such amounts are insufficient, in the manner set forth in the
Prospectus Supplement and Agreement for the related Series.

INSURANCE

         Unless otherwise specified in the applicable Prospectus Supplement,
the Agreement for each Series will require that the Master Servicer maintain or
require each Borrower to maintain insurance in accordance with the related
Mortgage, which generally will include a standard fire and hazard insurance


                                      22
<PAGE>

policy with extended coverage. To the extent required by the related Mortgage,
the coverage of each such standard hazard insurance policy will be in an amount
that is not less than the lesser of the full replacement cost of the
improvements securing such Mortgage Loan or the outstanding principal balance
owing on such Mortgage Loan. If a Mortgaged Property was located at the time of
origination of the related Mortgage Loan in a federally designated special
flood hazard area, the Master Servicer will also maintain or require the
related Borrower to maintain flood insurance in an amount equal to the lesser
of the unpaid principal balance of the related Mortgage Loan and the maximum
amount obtainable with respect to the Mortgage Loan. To the extent set forth in
the related Prospectus Supplement, the cost of any such insurance maintained by
the Master Servicer will be an expense of the Trust Fund payable out of the
Collection Account. The Master Servicer will cause to be maintained fire and
hazard insurance with extended coverage on each REO Property in an amount which
is at least equal to the greater of (i) an amount not less than the amount
necessary to avoid the application of any coinsurance clause contained in the
related insurance policy and (ii) the replacement cost of the improvements
which are a part of such property. The cost of any such insurance with respect
to an REO Property will be an expense of the Trust Fund payable out of amounts
on deposit in the related REO Account or, if such amounts are insufficient,
from the Collection Account. The Master Servicer will maintain flood insurance
providing substantially the same coverage as described above on any REO
Property which was located in a federally designated special flood hazard area
at the time the related Mortgage Loan was originated. The related Agreement
will provide that the Master Servicer may satisfy its obligation to cause
hazard policies to be maintained by maintaining a master, or single interest
blanket, insurance policy insuring against losses on the Mortgage Loans or REO
Properties, as the case may be. The incremental cost of such insurance
allocable to any particular Mortgage Loan, if not borne by the related
Borrower, will be an expense of the Trust Fund. Alternatively, the Master
Servicer may satisfy its obligation by maintaining, at its expense, a blanket
policy (i.e., not a single interest or master policy) insuring against losses
on the Mortgage Loans or REO Properties, as the case may be. If such a blanket
policy contains a deductible clause, the Master Servicer will be obligated to
deposit in the Collection Account all sums which would have been deposited
therein but for such clause.

         In general, the standard form of fire and hazard extended coverage
policy will cover physical damage to, or destruction of, the improvements on
the Mortgaged Property caused by fire, lightning, explosion, smoke, windstorm,
hail, riot, strike and civil commotion, subject to the conditions and
exclusions particularized in each policy. Since the standard hazard insurance
policies relating to the Mortgage Loans will be underwritten by different
insurers and will cover Mortgaged Properties located in various states, such
policies will not contain identical terms and conditions. The most significant
terms thereof, however, generally will be determined by state law and
conditions. Most such policies typically will not cover any physical damage
resulting from war, revolution, governmental actions, floods and other
water-related causes, earth movement (including earthquakes, landslides and mud
flows), nuclear reaction, 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. Any losses incurred with respect to Mortgage Loans due to
uninsured risks (including earthquakes, mud flows and floods) or insufficient
hazard insurance proceeds could affect distributions to the Certificateholders.

         The standard hazard insurance policies covering Mortgaged Properties
securing Mortgage Loans typically will contain a "coinsurance" clause which, in
effect, will require the insured at all times to carry insurance of a specified
percentage (generally 80% to 90%) of the full replacement value of the
dwellings, structures and other improvements on the Mortgaged Property in order
to recover the full amount of any partial loss. If the insured's coverage falls
below this specified percentage, such clause will provide that the insurer's
liability in the event of partial loss will not exceed the greater of (i) the
actual cash value (the replacement cost less physical depreciation) of the
structures and other improvements damaged or destroyed and (ii) such proportion
of the loss, without deduction for 


                                      23
<PAGE>

depreciation, as the amount of insurance carried bears to the specified
percentage of the full replacement cost of such dwellings, structures and other
improvements.

         In addition, to the extent required by the related Mortgage, the
Master Servicer may require the Borrower to maintain other forms of insurance
including, but not limited to, loss of rent endorsements, business interruption
insurance and comprehensive public liability insurance, and the related
Agreement may require the Master Servicer to maintain public liability
insurance with respect to any REO Properties. Any cost incurred by the Master
Servicer in maintaining any such insurance policy will be added to the amount
owing under the Mortgage Loan where the terms of the Mortgage Loan so permit;
provided, however, that the addition of such cost will not be taken into
account for purposes of calculating the distribution to be made to
Certificateholders. Such costs may be recovered by the Master Servicer from the
Collection Account, with interest thereon, as provided by the Agreement.

         Unless otherwise specified in the applicable Prospectus Supplement, no
pool insurance policy, special hazard insurance policy, bankruptcy bond,
repurchase bond or guarantee insurance will be maintained with respect to the
Mortgage Loans, nor will any Mortgage Loan be subject to FHA insurance.

         The FHA is responsible for administering various federal programs,
including mortgage insurance, authorized under the National Housing Act of
1934, as amended, and the United States Housing Act of 1937, as amended. To the
extent specified in the related Prospectus Supplement, all or a portion of the
Mortgage Loans may be insured by the FHA. The Master Servicer will be required
to take such steps as are reasonably necessary to keep such insurance in full
force and effect.

FIDELITY BONDS AND ERRORS AND OMISSIONS INSURANCE

         Unless otherwise specified in the applicable Prospectus Supplement,
the Agreement for each Series will require that the Master Servicer obtain and
maintain in effect a fidelity bond or similar form of insurance coverage (which
may provide blanket coverage) or any combination thereof insuring against loss
occasioned by fraud, theft or other intentional misconduct of the officers,
employees and agents of the Master Servicer. The related Agreement will allow
the Master Servicer to self-insure against loss occasioned by the errors and
omissions of the officers, employees and agents of the Master Servicer so long
as certain criteria set forth in the Agreement are met.

SERVICING COMPENSATION AND PAYMENT OF EXPENSES

         The Master Servicer's principal compensation for its activities under
the Agreement for each Series will come from the payment to it or retention by
it, with respect to each Mortgage Loan, of a "Servicing Fee" (as defined in the
related Prospectus Supplement). The exact amount and calculation of such
Servicing Fee will be established in the Prospectus Supplement and Agreement
for the related Series. Since the aggregate unpaid principal balance of the
Mortgage Loans will generally decline over time, the Master Servicer's
servicing compensation will ordinarily decrease as the Mortgage Loans amortize.

           In addition, the Agreement for a Series may provide that the Master
Servicer be entitled to receive, as additional compensation, (i) Prepayment
Premiums, late fees and certain other fees collected from Borrowers and (ii)
any interest or other income earned on funds deposited in the Collection
Account (as described under "DESCRIPTION OF THE CERTIFICATES -- Accounts") and,
except to the extent such income is required to be paid to the related
Borrowers, the Escrow Account.

         Unless otherwise specified in the related Prospectus Supplement, the
Master Servicer will pay the fees and expenses of the Trustee.



                                      24
<PAGE>

         If the Master Servicer subcontracts the servicing of Specially
Serviced Mortgage Loans to a Special Servicer, the exact amount and calculation
of the Special Servicer Fee will be established in the Prospectus Supplement
and Agreement for the related Series.

         In addition to the compensation described above, the Master Servicer
(or any other party specified in the applicable Prospectus Supplement) may
retain, or be entitled to the reimbursement of, such other amounts and expenses
as are described in the applicable Prospectus Supplement.

ADVANCES

         The applicable Prospectus Supplement will set forth the obligations,
if any, of the Master Servicer to make any advances with respect to delinquent
payments on Mortgage Loans, payments of taxes, insurance and Property
Protection Expenses or otherwise. Any such advances will be made in the form
and manner described in the Prospectus Supplement and Agreement for the related
Series.

MODIFICATIONS, WAIVERS AND AMENDMENTS

         If so specified in the related Prospectus Supplement, the Agreement
for each Series will provide that the Master Servicer or the Special Servicer,
if any, may have the discretion, subject to certain conditions set forth
herein, to modify, waive or amend certain of the terms of any Mortgage Loan
without the consent of the Trustee or any Certificateholder. The extent to
which the Master Servicer or the Special Servicer, if any, may modify, waive or
amend any terms of the Mortgage Loans without such consent will be specified in
the related Prospectus Supplement.

         The Special Servicer, if any, may, with respect to any Specially
Serviced Mortgage Loan, subject to the terms and conditions set forth in the
Agreement, modify, waive or amend the terms of such Mortgage Loan if the
Special Servicer determines that a material default has occurred or a payment
default has occurred or is reasonably foreseeable. The Special Servicer, if
any, may extend the maturity date of such Mortgage Loan to a date not later
than the date described in the related Prospectus Supplement.

         Unless otherwise provided in the applicable Prospectus Supplement, the
Special Servicer, if any, will not agree to any modification, waiver or
amendment of the payment terms of a Mortgage Loan unless the Special Servicer
has determined that such modification, waiver or amendment is reasonably likely
to produce a greater recovery on a present value basis than liquidation of the
Mortgage Loan. Prior to agreeing to any such modification, waiver or amendment
of the payment terms of a Mortgage Loan, the Special Servicer, if any, will
give notice thereof in the manner set forth in the Prospectus Supplement and
Agreement for the related Series.

         The Prospectus Supplement for a Series may describe other or different
provisions concerning the modification, waiver or amendment of the terms of the
related Mortgage Loans.

EVIDENCE OF COMPLIANCE

         The Agreement for each Series will provide that the Master Servicer,
at its expense, will cause a firm of independent public accountants to furnish
to the Trustee, annually on or before a date specified in the Agreement, a
statement as to compliance by the Master Servicer with the Agreement.

         In addition, the Agreement will provide that the Master Servicer will
deliver to the Trustee, annually on or before a date specified in the
Agreement, a statement signed by an officer to the effect that, 


                                      25
<PAGE>

based on a review of its activities during the preceding calendar year, to the
best of such officer's knowledge, the Master Servicer has fulfilled its
obligations under the Agreement throughout such year or, if there has been a
default in the fulfillment of any such obligation, specifying each such default
and the nature and status thereof.

CERTAIN MATTERS WITH RESPECT TO THE MASTER SERVICER, THE SPECIAL SERVICER AND 
THE TRUSTEE

         The Agreement for each Series will also provide that neither the
Master Servicer nor any of its directors, officers, employees or agents will be
under any liability to the Trust Fund or the Certificateholders for any action
taken, or for refraining from the taking of any action, in good faith pursuant
to the Agreement, or for errors in judgment; provided, however, that neither
the Master Servicer nor any such person will be protected against any breach of
representations or warranties made by the Master Servicer in the Agreement, or
any liability that would otherwise be imposed by reason of willful misfeasance,
bad faith, or negligence in the performance of its duties or by reason of
reckless disregard of its obligations and duties thereunder. The Agreement will
further provide that the Master Servicer and any of its directors, officers,
employees or agents 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 Certificates,
other than any loss, liability or expense incurred (i) by reason of willful
misfeasance, bad faith or negligence in the performance of its duties or by
reason of reckless disregard of its obligations and duties thereunder or (ii)
in certain other circumstances specified in the Agreement. Any loss resulting
from such indemnification will reduce amounts distributable to
Certificateholders and will be borne pro rata by all Certificateholders without
regard to subordination, if any, of one Class to another.

         Unless otherwise provided in the related Prospectus Supplement, the
Master Servicer may not resign from its obligations and duties under the
Agreement except upon a determination that its duties thereunder are no longer
permissible under applicable law. No such resignation will become effective
until the Trustee or a successor Master Servicer has assumed the Master
Servicer's obligations and duties under the Agreement.

         If the Master Servicer subcontracts the servicing of Specially
Serviced Mortgage Loans to a Special Servicer, the standard of care for, and
any indemnification to be provided to, the Special Servicer will be set forth
in the related Agreement.

         The Trustee under each Agreement will be named in the applicable
Prospectus Supplement. The commercial bank or trust company serving as Trustee
may have normal banking relationships with the Depositor and/or its affiliates
and with the Master Servicer and/or its affiliates.

         The Trustee may resign from its obligations under the Agreement at any
time, in which event a successor Trustee will be appointed. In addition, the
Depositor may remove the Trustee if the Trustee ceases to be eligible to act as
Trustee under the Agreement or if the Trustee becomes insolvent, at which time
the Depositor will become obligated to appoint a successor Trustee. The Trustee
may also be removed at any time by the Holders of Certificates evidencing the
Voting Rights specified in the applicable Prospectus Supplement. Any
resignation and removal of the Trustee, and the appointment of a successor
Trustee, will not become effective until acceptance of such appointment by the
successor Trustee.

EVENTS OF DEFAULT

         Events of default (each, an "Event of Default") with respect to the
Master Servicer under the Agreement for each Series will, unless otherwise
provided in the applicable Prospectus Supplement, 


                                      26
<PAGE>

include: (i) any failure by the Master Servicer to remit to the Trustee for
deposit in the Distribution Account for distribution to Certificateholders any
payment required to be made by the Master Servicer under the terms of the
Agreement at least one business day prior to the related Distribution Date;
(ii) any failure on the part of the Master Servicer duly to observe or perform
in any material respect any other of the covenants or agreements on the part of
the Master Servicer, which failure continues unremedied for a period of 90 days
after written notice of such failure has been given to the Master Servicer;
(iii) the entering against the Master Servicer of a decree or order of a court,
agency or supervisory authority for the appointment of a conservator or
receiver or liquidator in any insolvency, readjustment of debt, marshalling of
assets and liabilities or similar proceedings of or relating to the Master
Servicer, or for the winding-up or liquidation of its affairs; provided that
any such decree or order shall have remained in force undischarged or unstayed
for a period of 60 days; (iv) the consent by the Master Servicer to the
appointment of a conservator or receiver or liquidator or liquidating committee
in any insolvency, readjustment of debt, marshalling of assets and liabilities,
voluntary liquidation or similar proceedings of or relating to the Master
Servicer or of or relating to all or substantially all of its property; and (v)
the admission by the Master Servicer in writing of its inability to pay its
debts generally as they become due, the filing by the Master Servicer of a
petition to take advantage of any applicable insolvency or reorganization
statute or the making of an assignment for the benefit of its creditors or the
voluntary suspension of the payment of its obligations.

         As long as an Event of Default remains unremedied, the Trustee may,
and (a) at the written direction of the Holders of Certificates (other than
Residual Interest Certificates) entitled to at least 25% of the aggregate
Voting Rights of the Certificates of any Class in the case of an Event of
Default described in clause (i) above, (b) at the written direction of Holders
of Certificates holding at least 25% of all of the Voting Rights, or (c) in all
cases of an Event of Default described in clauses (ii) through (v) above, shall
terminate all of the rights and obligations of the Master Servicer whereupon
the Trustee or another successor Master Servicer appointed by the Trustee will
succeed to all authority and power of the Master Servicer under the Agreement
and will be entitled to similar compensation arrangements. "Voting Rights"
means the portion of the voting rights of all Certificates that is allocated to
any Certificate in accordance with the terms of the Agreement.

                                  ENHANCEMENT

GENERAL

         If specified in the related Prospectus Supplement for any Series,
credit enhancement may be provided with respect to one or more Classes thereof
or the related Mortgage Loans (the "Enhancement"). Enhancement may be in the
form of a letter of credit, the subordination of one or more Classes of the
Certificates of such Series, the establishment of one or more reserve funds,
overcollateralization, cross collateralization provisions in the Mortgage
Loans, certificate guarantee insurance, the use of cross-support features or
another method of Enhancement described in the related Prospectus Supplement,
or any combination of the foregoing.

         Unless otherwise specified in the related Prospectus Supplement for a
Series, the Enhancement will not provide protection against all risks of loss
and will not guarantee repayment of the entire principal balance of the
Certificates and interest thereon. If losses occur which exceed the amount
covered by Enhancement or which are not covered by the Enhancement,
Certificateholders will bear their allocable share of deficiencies.

         If Enhancement is provided with respect to a Series, or the related
Mortgage Loans, the applicable Prospectus Supplement will include a description
of (a) the amount payable under such Enhancement, (b) any conditions to payment
thereunder not otherwise described herein, (c) the conditions


                                      27
<PAGE>

(if any) under which the amount payable under such Enhancement may be reduced
and under which such Enhancement may be terminated or replaced and (d) the
material provisions of any agreement relating to such Enhancement.
Additionally, the applicable Prospectus Supplement will set forth certain
information with respect to the issuer of any third-party Enhancement,
including (i) a brief description of its principal business activities, (ii)
its principal place of business, place of incorporation and the jurisdiction
under which it is chartered or licensed to do business, (iii) if applicable,
the identity of regulatory agencies which exercise primary jurisdiction over
the conduct of its business and (iv) its total assets, and its stockholders' or
policyholders' surplus, if applicable, as of the date specified in such
Prospectus Supplement.

SUBORDINATE CERTIFICATES

         If so specified in the related Prospectus Supplement, one or more
Classes of a Series may be Subordinate Certificates. If so specified in the
related Prospectus Supplement, the rights of the Holders of subordinate
Certificates (the "Subordinate Certificates") to receive distributions of
principal and interest from the Collection Account on any Distribution Date
will be subordinated to such rights of the Holders of senior Certificates (the
"Senior Certificates") to the extent specified in the related Prospectus
Supplement. The Agreement may require a trustee that is not the Trustee to be
appointed to act on behalf of Holders of Subordinate Certificates.

         A Series may include one or more Classes of Subordinate Certificates
entitled to receive cash flows remaining after distributions are made to all
other Senior Certificates of such Series. Such right to receive payments will
effectively be subordinate to the rights of other Holders of Senior
Certificates. A Series may also include one or more Classes of Subordinate
Certificates entitled to receive cash flows remaining after distributions are
made to other Subordinate Certificates of such Series. If so specified in the
related Prospectus Supplement, the subordination of a Class may apply only in
the event of (or may be limited to) certain types of losses not covered by
insurance policies or other credit support, such as losses arising from damage
to property securing a Mortgage Loan not covered by standard hazard insurance
policies.

         The related Prospectus Supplement will set forth information
concerning the amount of subordination of a Class or Classes of Subordinate
Certificates in a Series, the circumstances in which such subordination will be
applicable, the manner, if any, in which the amount of subordination will
decrease over time, the manner of funding any related Reserve Fund and the
conditions under which amounts in any applicable Reserve Fund will be used to
make distributions to Holders of Senior Certificates and/or to Holders of
Subordinate Certificates or be released from the applicable Trust Fund. If cash
flows otherwise distributable to Holders of Subordinate Certificates secured by
a Mortgage Loan Group will be used as credit support for Holders of Senior
Certificates secured by another Mortgage Loan Group within the Trust Fund, the
applicable Prospectus Supplement will specify the manner and conditions for
applying such a cross-support feature.

CROSS-SUPPORT FEATURES

         If the Mortgage Pool for a Series is divided into separate Mortgage
Loan Groups, each securing a separate Class or Classes of a Series, credit
support may be provided by a cross-support feature which requires that
distributions be made on Senior Certificates secured by one Mortgage Loan Group
prior to distributions on Subordinate Certificates secured by another Mortgage
Loan Group within the Trust Fund. The related Prospectus Supplement for a
Series which includes a cross-support feature will describe the manner and
conditions for applying such cross-support feature.


                                      28
<PAGE>


LETTER OF CREDIT

         If specified in the related Prospectus Supplement, a letter of credit
with respect to a Series of Certificates will be issued by the bank or
financial institution specified in such Prospectus Supplement (the "L/C Bank").
Under the letter of credit, the L/C Bank will be obligated to honor drawings
thereunder in an aggregate fixed dollar amount, net of unreimbursed payments
thereunder, equal to the percentage specified in the related Prospectus
Supplement of the aggregate principal balance of the Mortgage Loans on the
applicable Cut-Off Date or of one or more Classes of Certificates (the "L/C
Percentage"). If so specified in the related Prospectus Supplement, the letter
of credit may permit drawings in the event of losses not covered by insurance
policies or other credit support, such as losses arising from damage not
covered by standard hazard insurance policies. The amount available under the
letter of credit will, in all cases, be reduced to the extent of the
unreimbursed payments thereunder. The obligations of the L/C Bank under the
letter of credit for each Series of Certificates will expire at the earlier of
the date specified in the related Prospectus Supplement or the termination of
the Trust Fund. A copy of the letter of credit for a Series, if any, will be
filed with the Commission as an exhibit to a Current Report on Form 8-K to be
filed within 15 days of issuance of the Certificates of the applicable Series.

CERTIFICATE GUARANTEE INSURANCE

         If so specified in the related Prospectus Supplement, certificate
guarantee insurance, if any, with respect to a Series of Certificates will be
provided by one or more insurance companies. Such certificate guarantee
insurance will guarantee, with respect to one or more Classes of Certificates
of the applicable Series, timely distributions of interest and full
distributions of principal on the basis of a schedule of principal
distributions set forth in or determined in the manner specified in the related
Prospectus Supplement. If so specified in the related Prospectus Supplement,
the certificate guarantee insurance will also guarantee against any payment
made to a Certificateholder which is subsequently covered as a "voidable
preference" payment under the Bankruptcy Code. A copy of the certificate
guarantee insurance for a Series, if any, will be filed with the Commission as
an exhibit to a Current Report on Form 8-K to be filed with the Commission
within 15 days of issuance of the Certificates of the applicable Series.

RESERVE FUNDS

         If specified in the related Prospectus Supplement, one or more reserve
funds (each, a "Reserve Fund") may be established with respect to a Series, in
which cash, a letter of credit, Permitted Investments or a combination thereof,
in the amounts, if any, so specified in the related Prospectus Supplement will
be deposited. The Reserve Funds for a Series may also be funded over time by
depositing therein a specified amount of the distributions received on the
applicable Mortgage Loans if specified in the related Prospectus Supplement.
The Depositor may pledge the Reserve Funds to a separate collateral agent
specified in the related Prospectus Supplement.

         Amounts on deposit in any Reserve Fund for a Series, together with the
reinvestment income thereon, if any, will be applied by the Trustee for the
purposes, in the manner, and to the extent specified in the related Prospectus
Supplement. A Reserve Fund may be provided to increase the likelihood of timely
payments of principal of and interest on the Certificates, if required as a
condition to the rating of such Series by each Rating Agency. If so specified
in the related Prospectus Supplement, Reserve Funds may be established to
provide limited protection, in an amount satisfactory to each Rating Agency,
against certain types of losses not covered by insurance policies or other
credit support, such as losses arising from damage not covered by standard
hazard insurance policies. Reserve Funds may also be established for other
purposes and in such amounts as will be specified in the related Prospectus
Supplement. Following each Distribution Date amounts in any Reserve Fund in
excess of any amount required to be maintained therein may be released from the
Reserve Fund under the conditions and to the 


                                      29
<PAGE>

be applied to make distributions to Certificateholders and use of investment
earnings from the Reserve Fund, if any.

                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS

         The following discussion contains summaries of certain legal aspects
of mortgage loans which are general in nature. Because many of the legal
aspects of mortgage loans are governed by applicable state laws (which may vary
substantially), the following summaries do not purport to be complete, to
reflect the laws of any particular state, to reflect all the laws applicable to
any particular Mortgage Loan or to encompass the laws of all states in which
the properties securing the Mortgage Loans are situated. The summaries are
qualified in their entirety by reference to the applicable federal and state
laws governing the Mortgage Loans. In the event that the Trust Fund for a given
Series includes Mortgage Loans having characteristics other than as described
below, the applicable Prospectus Supplement will set forth additional legal
aspects relating thereto.

MORTGAGES AND DEEDS OF TRUST GENERALLY

         The Mortgage Loans (other than Installment Contracts) included in the
Mortgage Pool for a Series will consist of (or, in the case of mortgage
pass-through certificates, be supported by) loans secured by either mortgages
or deeds of trust or other similar security instruments. There are two parties
to a mortgage, the mortgagor, who is the borrower and owner of the mortgaged
property, and the mortgagee, who is the lender. In a mortgage transaction, the
mortgagor delivers to the mortgagee a note, bond or other written evidence of
indebtedness and a mortgage. A mortgage creates a lien upon the real property
encumbered by the mortgage as security for the obligation evidenced by the
note, bond or other evidence of indebtedness. Although a deed of trust is
similar to a mortgage, a deed of trust has three parties, the borrower-property
owner called the trustor (similar to a mortgagor), a lender called the
beneficiary (similar to a mortgagee), and a third-party grantee called the
trustee. Under a deed of trust, the borrower irrevocably grants the property to
the trustee, until the debt is paid, in trust for the benefit of the
beneficiary to secure payment of the obligation generally with a power of sale.
The trustee's authority under a deed of trust and the mortgagee's authority
under a mortgage are governed by applicable law, the express provisions of the
deed of trust or mortgage, and, in some cases, the directions of the
beneficiary.

         The real property covered by a mortgage is most often the fee estate
in land and improvements. However, a mortgage may encumber other interests in
real property such as a tenant's interest in a lease of 


                                      30
<PAGE>

land or improvements, or both, and the leasehold estate created by such lease.
A mortgage covering an interest in real property other than the fee estate
requires special provisions in the instrument creating such interest or in the
mortgage to protect the mortgagee against termination of such interest before
the mortgage is paid. Certain representations and warranties in the related
Agreement will be made with respect to the Mortgage Loans which are secured by
an interest in a leasehold estate.

         Priority of the lien on mortgaged property created by mortgages and
deeds of trust depends on their terms and, generally, on the order of filing
with a state, county or municipal office, although such priority may in some
states be altered by the mortgagee's or beneficiary's knowledge of unrecorded
liens, leases or encumbrances against the mortgaged property. However, filing
or recording does not establish priority over governmental claims for real
estate taxes and assessments or, in some states, for reimbursement of
remediation costs of certain environmental conditions. See "--Environmental
Risks." In addition, the Code provides priority to certain tax liens over the
lien of the mortgage.

INSTALLMENT CONTRACTS

         The Mortgage Loans included in the Mortgage Pool for a Series may also
consist of Installment Contracts. Under an Installment Contract the seller
(hereinafter referred to in this Section as the "lender") retains legal title
to the property and enters into an agreement with the purchaser (hereinafter
referred to in this Section as the "borrower") for the payment of the purchase
price, plus interest, over the term of such contract. Only after full
performance by the borrower of the contract is the lender obligated to convey
title to the real estate to the purchaser. As with mortgage or deed of trust
financing, during the effective period of the Installment Contract, the
borrower is generally responsible for maintaining the property in good
condition and for paying real estate taxes, assessments and hazard insurance
premiums associated with the property.

         The method of enforcing the rights of the lender under an Installment
Contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to its terms. The terms of Installment Contracts
generally provide that upon a default by the borrower, the borrower loses his
or her right to occupy the property, the entire indebtedness is accelerated,
and the borrower's equitable interest in the property is forfeited. The lender
in such a situation does not have to foreclose in order to obtain title to the
property, although in some cases a quiet title action is in order if the
borrower has filed the Installment Contract in local land records and an
ejectment action may be necessary to recover possession. In a few states,
particularly in cases of borrower default during the early years of an
Installment Contract, the courts will permit ejectment of the borrower and a
forfeiture of his or her interest in the property. However, most state
legislatures have enacted provisions by analogy to mortgage law protecting
borrowers under Installment Contracts from the harsh consequences of
forfeiture. Under such statutes, a judicial or nonjudicial foreclosure may be
required, the lender may be required to give notice of default and the borrower
may be granted some grace period during which the contract may be reinstated
upon full payment of the default amount and the borrower may have a
post-foreclosur statutory redemption right. In other states, courts in equity
may permit a borrower with significant investment in the property under an
Installment Contract for the sale of real estate to share in the proceeds of
sale of the property after the indebtedness is repaid or may otherwise refuse
to enforce the forfeiture clause. Nevertheless, generally speaking, the
lender's procedures for obtaining possession and clear title under an
Installment Contract for the sale of real estate in a given state are simpler
and less time-consuming and costly than are the procedures for foreclosing and
obtaining clear title to a mortgaged property.



                                      31

JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGEES OR BENEFICIARIES

         Some of the Mortgage Loans included in the Mortgage Pool for a Series
will be secured by junior mortgages or deeds of trust which are subordinate to
senior mortgages or deeds of trust held by other lenders or institutional
investors. The rights of the Trust Fund (and therefore the Certificateholders),
as beneficiary under a junior deed of trust or as mortgagee under a junior
mortgage, are subordinate to those of the mortgagee or beneficiary under the
senior mortgage or deed of trust, including the prior rights of the senior
mortgagee or beneficiary to receive rents, hazard insurance and condemnation
proceeds and to cause the property securing the Mortgage Loan to be sold upon
default of the mortgagor or trustor, thereby extinguishing the junior
mortgagee's or junior beneficiary's lien unless the Master Servicer asserts its
subordinate interest in a property in foreclosure litigation or satisfies the
defaulted senior loan. As discussed more fully below, in many states a junior
mortgagee or beneficiary may satisfy a defaulted senior loan in full, or may
cure such default and bring the senior loan current, in either event adding the
amounts expended to the balance due on the junior loan. Absent a provision in
the senior mortgage, no notice of default is required to be given to the junior
mortgagee.

         The form of the mortgage or deed of trust used by many institutional
lenders confers on the mortgagee or beneficiary the right both to receive all
proceeds collected under any hazard insurance policy and all awards made in
connection with any condemnation proceedings, and to apply such proceeds and
awards to any indebtedness secured by the mortgage or deed of trust, in such
order as the mortgagee or beneficiary may determine. Thus, in the event
improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under the senior mortgage or deed of trust will have the prior
right to collect any insurance proceeds payable under a hazard insurance policy
and any award of damages in connection with the condemnation and to apply the
same to the indebtedness secured by the senior mortgage or deed of trust.
Proceeds in excess of the amount of senior mortgage indebtedness will, in most
cases, be applied to the indebtedness of a junior mortgage or deed of trust.
The laws of certain states may limit the ability of mortgagees or beneficiaries
to apply the proceeds of hazard insurance and partial condemnation awards to
the secured indebtedness. In such states, the mortgagor or trustor must be
allowed to use the proceeds of hazard insurance to repair the damage unless the
security of the mortgagee or beneficiary has been impaired. Similarly, in
certain states, the mortgagee or beneficiary is entitled to the award for a
partial condemnation of the real property security only to the extent that its
security is impaired.

         The form of mortgage or deed of trust used by many institutional
lenders typically contains a "future advance" clause, which provides, in
essence, that additional amounts advanced to or on behalf of the mortgagor or
trustor by the mortgagee or beneficiary are to be secured by the mortgage or
deed of trust. While such a clause is valid under the laws of most states, the
priority of any advance made under the clause depends, in some states, on
whether the advance was an "obligatory" or "optional" advance. If the mortgagee
or beneficiary is obligated to advance the additional amounts, the advance may
be entitled to receive the same priority as amounts initially made under the
mortgage or deed of trust, notwithstanding that there may be intervening junior
mortgages or deeds of trust and other liens between the date of recording of
the mortgage or deed of trust and the date of the future advance, and
notwithstanding that the mortgagee or beneficiary had actual knowledge of such
intervening junior mortgages or deeds of trust and other liens at the time of
the advance. Where the mortgagee or beneficiary is not obligated to advance the
additional amounts and has actual knowledge of the intervening junior mortgages
or deeds of trust and other liens, the advance may be subordinate to such
intervening junior mortgages or deeds of trust and other liens. Priority of
advances under a"future advance" clause rests, in many other states, on state
law giving priority to all advances made under the loan agreement up to a
"credit limit" amount stated in the recorded mortgage.



                                      32
<PAGE>

         Another provision typically found in the form of the mortgage or deed
of trust used by many institutional lenders obligates the mortgagor or trustor
to pay before delinquency all taxes and assessments on the property and, when
due, all encumbrances, charges and liens on the property which appear prior to
the mortgage or deed of trust, to provide and maintain fire insurance on the
property, to maintain and repair the property and not to commit or permit any
waste thereof, and to appear in and defend any action or proceeding purporting
to affect the property or the rights of the mortgagee or beneficiary under the
mortgage or deed of trust. Upon a failure of the mortgagor or trustor to
perform any of these obligations, the mortgagee or beneficiary is given the
right under the mortgage or deed of trust to perform the obligation itself, at
its election, with the mortgagor or trustor agreeing to reimburse the mortgagee
or beneficiary for any sums expended by the mortgagee or beneficiary on behalf
of the trustor. All sums so expended by the mortgagee or beneficiary become
part of the indebtedness secured by the mortgage or deed of trust.

         The form of mortgage or deed of trust used by many institutional
lenders typically requires the mortgagor or trustor to obtain the consent of
the mortgagee or beneficiary in respect of actions affecting the mortgaged
property, including, without limitation, leasing activities (including new
leases and termination or modification of existing leases), alterations and
improvements to buildings forming a part of the mortgaged property and
management and leasing agreements for the mortgaged property. Tenants will
often refuse to execute a lease unless the mortgagee or beneficiary executes a
written agreement with the tenant not to disturb the tenant's possession of its
premises in the event of a foreclosure. A senior mortgagee or beneficiary may
refuse to consent to matters approved by a junior mortgagee or beneficiary with
the result that the value of the security for the junior mortgage or deed of
trust is diminished. For example, a senior mortgagee or beneficiary may decide
not to approve a lease or to refuse to grant to a tenant a non-disturbance
agreement. If, as a result, the lease is not executed, the value of the
mortgaged property may be diminished.

FORECLOSURE

         Foreclosure of a mortgage is generally accomplished by judicial action
initiated by the service of legal pleadings upon all necessary parties having
an interest in the real property. Delays in completion of foreclosure may
occasionally result from difficulties in locating necessary party defendants.
When the mortgagee's right to foreclose is contested, the legal proceedings
necessary to resolve the issue can be time-consuming. A judicial foreclosure
may be subject to most of the delays and expenses of other litigation,
sometimes requiring up to several years to complete. At the completion of the
judicial foreclosure proceedings, if the mortgagee prevails, the court
ordinarily issues a judgment of foreclosure and appoints a referee or other
designated official to conduct the sale of the property. Such sales are made in
accordance with procedures which vary from state to state. The purchaser at
such sale acquires the estate or interest in real property covered by the
mortgage. If the mortgage covered the tenant's interest in a lease and
leasehold estate, the purchaser will acquire such tenant's interest subject to
the tenant's obligations under the lease to pay rent and perform other
covenants contained therein.

         In a majority of cases, foreclosure of a deed of trust is accomplished
by a non-judicial trustee's sale under a specific provision in the deed of
trust and/or applicable statutory requirements which authorizes the trustee,
generally following a request from the beneficiary, to sell the property at
public sale upon any default by the trustor under the terms of the note or deed
of trust. A number of states may also require that a beneficiary provide notice
of acceleration of a note to the trustor. Notice requirements under a trustee's
sale vary from state to state. In some states, prior to the trustee's sale the
trustee must record a notice of default and send a copy to the trustor, to any
person who has recorded a request for a copy of a notice of default and notice
of sale and to any successor in interest to the trustor. In addition, the
trustee must provide notice in some states to any other person having an
interest in the real property, including any junior lienholders, and to certain
other persons connected with the deed of trust. In some 


                                      33
<PAGE>

states, the trustor, or any other person having a junior encumbrance on the
real estate, may, during a reinstatement period, cure the default by paying the
entire amount in arrears plus the costs and expenses (in some states, limited
to reasonable costs and expenses) incurred in enforcing the obligation.
Generally, state law controls the amount of foreclosure expenses and costs,
including attorneys' fees, which may be recovered by a beneficiary. If the deed
of trust is not reinstated, a notice of sale must be posted in a public place
and, in most states, published for a specific period of time in one or more
newspapers. In addition, some state laws require that a copy of the notice of
sale be posted on the property and sent to all parties having an interest in
the real property.

         In case of foreclosure under either a mortgage or a deed of trust, the
sale by the referee or other designated official or by the trustee is often a
public sale. However, because of the difficulty a potential buyer at the sale
might have in determining the exact status of title to the property subject to
the lien of the mortgage or deed of trust and the redemption rights that may
exist (see "--Statutory Rights of Redemption" below), and because the physical
condition and financial performance of the property may have deteriorated
during the foreclosure proceedings and/or for a variety of other reasons, a
third party may be unwilling to purchase the property at the foreclosure sale.
Some states require that the lender disclose to potential bidders at a
trustee's sale all known facts materially affecting the value of the property.
Such disclosure may have an adverse effect on the trustee's ability to sell the
property or the sale price thereof. Potential buyers may further question the
prudence of purchasing 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, other decisions that have followed
the reasoning of Durrett and the codification of the Durrett reasoning in the
federal bankruptcy code, as amended from time to time (11 U.S.C.) (the
"Bankruptcy Code"). Under the reasoning of Durrett, even a non-collusive,
regularly conducted foreclosure sale may be a fraudulent transfer, regardless
of the parties' intent, and, therefore, may be rescinded in favor of the
bankrupt's estate, if (i) the foreclosure sale is held while the debtor is
insolvent and not more than one year prior to the filing of the bankruptcy
petition (or if applicable state fraudulent conveyance law also allows the
avoidance of such a foreclosure sale, the applicable state statute of
limitations if the bankruptcy trustee elects to proceed under state fraudulent
conveyance law), and (ii) the price paid for the foreclosed property does not
represent "fair consideration." In May 1994 the Supreme Court held in BFP v.
RTC that in the absence of actual intent to defraud a non-collusive, regularly
conducted foreclosure sale cannot be rescinded as a fraudulent transfer under
federal bankruptcy law. However, BFP does not address state law, and the impact
of BFP on potential buyers' willingness to purchase property at a foreclosure
sale cannot yet be assessed. Prior to BFP, a common practice was for the lender
to purchase the property from the trustee, referee or other designated official
for an amount equal to the outstanding principal amount of the indebtedness
secured by the mortgage or deed of trust, together with accrued and unpaid
interest and the expenses of foreclosure, in which event, if the amount bid by
the lender equals the full amount of such debt, interest and expenses, the
mortgagee's debt will be extinguished. Thereafter, the lender will assume the
burdens of ownership, including paying operating expenses and real estate taxes
and making repairs. The lender is then obligated as an owner until it can
arrange a sale of the property to a third party. Frequently, the lender employs
a third-party management company to manage and operate the property. The costs
of operating and maintaining commercial property may be significant and may be
greater than the income derived from that property. The costs of management and
operation of those mortgaged properties which are hotels, motels or nursing or
convalescent homes or hospitals may be particularly significant because of the
expertise, knowledge and, with respect to nursing or convalescent homes or
hospitals, regulatory compliance, required to run such operations and the
effect which foreclosure and a change in ownership may have on the public's and
the industry's (including franchisors') perception of the quality of such
operations. The lender will commonly obtain the services of a real estate
broker and pay the broker's commission in connection with the sale of the
property. Depending upon market conditions, the ultimate proceeds of the sale
of the property may not equal the lender's investment in the property.
Moreover, a lender commonly incurs substantial legal fees and court costs in
acquiring a mortgaged property through 


                                      34
<PAGE>

contested foreclosure and/or bankruptcy proceedings. Furthermore, some states
require that any environmental hazards be eliminated before a property may be
resold. In addition, a lender may be responsible under federal or state law for
the cost of cleaning up a mortgaged property that is environmentally
contaminated. See "--Environmental Risks" below. As a result, a lender could
realize an overall loss on a mortgage loan even if the related mortgaged
property is sold at foreclosure or resold after it is acquired through
foreclosure for an amount equal to the full outstanding principal amount of the
mortgage loan, plus accrued interest.

         In foreclosure proceedings, some courts have applied general equitable
principles. These 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 of the borrower's default and the likelihood that the
borrower will be able to reinstate the loan. In some cases, courts have
substituted their judgment for the lender's judgment and have required that
lenders reinstate loans or recast payment schedules in order to accommodate
borrowers who are suffering from temporary financial disability. In other
cases, courts have limited the right of the lender to foreclose if the default
under the mortgage instrument is not monetary, such as the borrower's failing
to maintain adequately the property or the borrower's executing a second
mortgage or deed of trust affecting the property. Finally, some courts have
been faced with the issue of whether or not federal or state constitutional
provisions reflecting due process concerns for adequate notice require that
borrowers under deeds of trust or mortgages receive notices in addition to the
statutorily prescribed minimum. For the most part, these cases have upheld the
notice provisions as being reasonable or have found that the sale by a trustee
under a deed of trust, or under a mortgage having a power of sale, does not
involve sufficient state action to afford constitutional protections to the
borrower.

         Under the REMIC provisions of the Code and under the related
Agreement, the Master Servicer or Special Servicer, if any, may be permitted to
hire an independent contractor to operate any REO Property. The costs of such
operation may be significantly greater than the costs of direct operation by
the Master Servicer or Special Servicer, if any. See "SERVICING OF THE MORTGAGE
LOANS -- Collections and Other Servicing Procedures."

ENVIRONMENTAL RISKS

         Real property pledged as security to a lender may be subject to
potential environmental risks. Of particular concern may be those mortgaged
properties which are, or have been, the site of manufacturing, industrial or
disposal activity. Such environmental risks may give rise to a diminution in
value of property securing any Mortgage Loan or, as more fully described below,
liability for cleanup costs or other remedial actions, which liability could
exceed the value of such property or the principal balance of the related
Mortgage Loan. In certain circumstances, a lender may choose not to foreclose
on contaminated property rather than risk incurring liability for remedial
actions.

         Under the laws of certain states where the Mortgaged Properties are
located, the owner's failure to perform remedial actions required under
environmental laws may in certain circumstances give rise to a lien on the
Mortgaged Property to ensure the reimbursement of remedial costs incurred by
the state. In several states such lien has priority over the lien of an
existing mortgage against such property. Because the costs of remedial action
could be substantial, the value of a Mortgaged Property as collateral for a
Mortgage Loan could be adversely affected by the existence of an environmental
condition giving rise to a lien.

         Under some circumstances, cleanup costs, or the obligation to take
remedial actions, can be imposed on a secured lender such as the Trust Fund
with respect to each Series. Under the laws of some 


                                      35
<PAGE>

states and under the federal Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, as amended ("CERCLA"), current
ownership or operation of a property provides a sufficient basis for imposing
liability for the costs of addressing prior or current releases or threatened
releases of hazardous substances on that property. Under such laws, a secured
lender who holds indicia of ownership primarily to protect its interest in a
property may, by virtue of holding such indicia, fall within the literal terms
of the definition of "owner or operator"; consequently, such laws often
specifically exclude such a secured lender from the definitions of "owner" or
"operator", provided that the lender does not participate in the management of
the facility.

         Whether actions taken by a secured creditor would constitute such
participation in the management of a facility or property, so that the lender
loses the protection of the secured creditor exclusion, has been a matter of
judicial interpretation of the statutory language, and court decisions have
historically been inconsistent. In 1990, the United States Court of Appeals for
the Eleventh Circuit suggested, in United States v. Fleet Factors Corp., that
the mere capacity of the lender to influence a borrower's decisions regarding
disposal of hazardous substances was sufficient participation in the management
of the borrower's business to deny the protection of the secured creditor
exclusion to the lender, regardless of whether the lender actually exercised
such influence. Other judicial decisions did not interpret the secured creditor
exclusion as narrowly as did the Eleventh Circuit.

         This ambiguity appears to have been resolved by the enactment of the
Asset Conservation, Lender Liability and Deposit Insurance Protection Act of
1996 (the "Asset Conservation Act"), which took effect on September 30, 1996.
The Asset Conservation Act provides that in order to be deemed to have
participated in the management of a secured property, a lender must actually
participate in the operational affairs of the property or the borrower. The
Asset Conservation Act also provides that participation in the management of
the property does not include "merely having the capacity to influence, or
unexercised right to control" operations. Rather, a lender will lose the
protection of the secured creditor exclusion only if it exercises decision-
making control over the borrower's environmental compliance and hazardous
substance handling and disposal practices, or assumes day-to-day management of
all operational functions of the secured property.

         It should be noted that the secured creditor exclusion does not govern
liability for cleanup costs under federal laws other than CERCLA. CERCLA's
jurisdiction extends to the investigation and remediation of releases of
"hazardous substances". The definition of "hazardous substances" under CERCLA
specifically excludes petroleum products. Under federal law, the operation and
management of underground petroleum storage tanks (excluding heating oil) is
governed by Subtitle I of the Resource Conservation and Recovery Act ("RCRA").
Under the Asset Conservation Act, the protections accorded to lenders under
CERCLA are also accorded to the holders of security interests in underground
storage tanks. However, liability for cleanup of petroleum contamination will
most likely be governed by state law, which may not provide any specific
protection for secured creditors.

         Except as otherwise specified in the applicable Prospectus Supplement,
at the time the Mortgage Loans were originated, it is possible that no
environmental assessment or a very limited environmental assessment of the
Mortgaged Properties was conducted.

         The related Agreement will provide that the Master Servicer, acting on
behalf of the Trust Fund, may not acquire title to, or possession of, a
Mortgaged Party underlying a Mortgage Loan, take over its operation or take any
other action that might subject a given Trust Fund to liability under CERCLA or
comparable laws unless the Master Servicer has previously determined, based
upon a phase I or other specified environmental assessment prepared by a person
who regularly conducts such environmental assessments, that the Mortgaged
Property is in compliance with applicable environmental laws and that there are
no circumstances relating to use, management or disposal of any hazardous
substances for which 

                                      36
<PAGE>

investigation, monitoring, containment, clean-up or remediation could be
required under applicable environmental laws, or that it would be in the best
economic interest of a given Trust Fund to take such actions as are necessary
to bring the Mortgaged Property into compliance therewith or as may be required
under such laws. This requirement effectively precludes enforcement of the
security for the related Note until a satisfactory environmental assessment is
obtained or any required remedial action is taken, reducing the likelihood that
a given Trust Fund will become liable for any environmental conditions
affecting a Mortgaged Property, but making it more difficult to realize on the
security for the Mortgage Loan. However, there can be no assurance that any
environmental assessment obtained by the Master Servicer will detect all
possible environmental conditions or that the other requirements of the
Agreement, even if fully observed by the Master Servicer will in fact insulate
a given Trust Fund from liability for environmental conditions.

         If a lender is or becomes liable for clean-up costs, it may bring an
action for contribution against the current owners or operators, the owners or
operators at the time of on-site disposal activity or any other party who
contributed to the environmental hazard, but such persons or entities may be
bankrupt or otherwise judgment-proof. Furthermore, such action against the
Borrower may be adversely affected by the limitations on recourse in the loan
documents. Similarly, in some states anti-deficiency legislation and other
statutes requiring the lender to exhaust its security before bringing a
personal action against the borrower-trustor (see"--Anti-Deficiency
Legislation" below) may curtail the lender's ability to recover from its
borrower the environmental clean-up and other related costs and liabilities
incurred by the lender. Shortfalls occurring as the result of imposition of any
clean-up costs will be addressed in the Prospectus Supplement and Agreement for
the related Series.

STATUTORY RIGHTS OF REDEMPTION

         In some states, after foreclosure sale pursuant to a deed of trust or
a mortgage, the borrower 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 entire principal
balance of the loan, accrued interest and expenses of foreclosure. In other
states, redemption may be authorized if the former borrower pays only a portion
of the sums due. The effect of a statutory right of redemption is to diminish
the ability of the lender to sell the foreclosed property. The right of
redemption may defeat the title of any purchaser at a foreclosure sale or any
purchaser from the lender subsequent to a foreclosure sale. Certain states
permit a lender to avoid a post-sale redemption by waiving its right to a
deficiency judgment. Consequently, the practical effect of the redemption right
is often to force the lender to retain the property and pay the expenses of
ownership until the redemption period has run. In some states, there is no
right to redeem property after a trustee's sale under a deed of trust.

         Borrowers under Installment Contracts generally do not have the
benefits of redemption periods such as exist in the same jurisdiction for
mortgage loans. Where redemption statutes do exist under state laws for
Installment Contracts, the redemption period is usually far shorter than for
mortgages.

ANTI-DEFICIENCY LEGISLATION

         Some of the Mortgage Loans included in the Mortgage Pool for a Series
will be nonrecourse loans as to which, in the event of default by a Borrower,
recourse may be had only against the specific property pledged to secure the
related Mortgage Loan and not against the Borrower's other assets. Even if
recourse is available pursuant to the terms of the Mortgage Loan against the
Borrower's assets in addition to the Mortgaged Property, certain states have
imposed statutory prohibitions which impose prohibitions against or limitations
on such recourse. For example, some state 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 


                                      37
<PAGE>

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 states, the lender
has the option of bringing a personal action against the borrower on the debt
without first exhausting such security; however, in some of these states, the
lender, following judgment on such personal action, may be deemed to have
elected a remedy and may be precluded from exercising remedies with respect to
the security. Consequently, the practical effect of the election requirement,
when applicable, is that lenders will usually proceed first against the
security rather than bringing personal action against the borrower. 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 bids or the absence of bids at the judicial sale.

BANKRUPTCY LAWS

         Numerous statutory provisions, including the Bankruptcy Code and state
laws affording relief to debtors, may interfere with and delay the ability of
the secured mortgage lender to obtain payment of the loan, to realize upon
collateral and/or to 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
the bankruptcy petition, and, often, no interest or principal payments are made
during the course of the bankruptcy proceeding. The delay and 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, including, without limitation, any junior mortgagee or
beneficiary, may stay the senior lender from taking action to foreclose out
such junior lien. Certain of the Mortgaged Properties may have a junior
"wraparound" mortgage or deed of trust encumbering such Mortgaged Property. In
general terms, a "wraparound" mortgage is a junior mortgage where the full
amount of the mortgage is increased by an amount equal to the principal balance
of the senior mortgage and where the junior lender agrees to pay the senior
mortgage out of the payments received from the mortgagor under the "wraparound"
mortgage. As with other junior mortgages, the filing of a petition under the
Bankruptcy Code by or on behalf of such a "wrap" mortgagee may stay the senior
lender from taking action to foreclose upon such junior "wrap" mortgage.

         Under the Bankruptcy Code, provided certain substantive and procedural
safeguards for the lender are met, the amount and terms of a mortgage or deed
of trust secured by property of the debtor may be modified under certain
circumstances. The outstanding amount of the loan secured by the real property
may be reduced to the then current value of the property (with a corresponding
partial reduction of the amount of the lender's security interest), thus
leaving the lender a general unsecured creditor for the difference between such
value and the outstanding balance of the loan. Other modifications may include
the reduction in the amount of each monthly 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. Some bankruptcy
courts have approved plans, based on the particular facts of the reorganization
case, that effected the curing of a mortgage loan default by paying arrearages
over a number of years. Also, under the Bankruptcy Code, a bankruptcy court may
permit a debtor through its plan to de-accelerate a secured loan and to
reinstate the loan even though the lender accelerated the mortgage loan and
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.
This may be done even if the full amount due under the original loan is never
repaid. Other types of significant modifications to the terms of the mortgage
may be acceptable to the bankruptcy court, often depending on the particular
facts and circumstances of the specific case.



                                      38
<PAGE>

         A "deficient valuation" with respect to any mortgage loan is the
excess of (a)(i) the then outstanding principal balance of the mortgage loan,
plus (ii) accrued and unpaid interest and expenses reimbursable under the terms
of the related note to the date of the bankruptcy petition (collectively, the
"Outstanding Balance"), over (b) a valuation by a court of competent
jurisdiction of the mortgaged property which reduces the principal balance
receivable on such mortgage loan to an amount less than the Outstanding Balance
of the mortgage loan, which valuation results from a proceeding initiated under
the Bankruptcy Code. As used herein, "Deficient Valuation" means, with respect
to any Mortgage Loan, the deficient valuation described in the preceding
sentence, without giving effect to clause (a)(ii) thereof. If the terms of a
court order in respect of any retroactive Deficient Valuation provide for a
reduction in the indebtedness of a Mortgage Loan and the earlier maturity
thereof, the term Deficient Valuation includes an additional amount equal to
the excess, if any, of (a) the amount of principal that would have been due on
such Mortgage Loan for each month retroactively affected (i.e. each month
occurring after the effective date of such Deficient Valuation but before the
distribution of amounts in respect of such Deficient Valuation to
Certificateholders pursuant to the related Agreement), based on the original
payment terms and amortization schedule of such Mortgage Loan over (b) the
amount of principal due on such Mortgage Loan for each such retroactive month
(assuming the effect of such retroactive application according to such Mortgage
Loan's revised amortization schedule). A "Debt Service Reduction," with respect
to any Mortgage Loan, is a reduction in the scheduled monthly payment, as
described in the Agreement, for such Mortgage Loan by a court of competent
jurisdiction in a proceeding under the Bankruptcy Code, except such a reduction
resulting from a Deficient Valuation.

         Federal bankruptcy law may also interfere with or affect the ability
of the secured mortgage lender to enforce an assignment by a mortgagor of rents
and leases related to the mortgaged property if the related mortgagor is in a
bankruptcy proceeding. Under Section 362 of the Bankruptcy Code, the mortgagee
will be stayed from enforcing the assignment, and the legal proceedings
necessary to resolve the issue can be time-consuming and may result in
significant delays in the receipt of the rents. Rents may also escape an
assignment thereof (i) if the assignment is not fully perfected under state law
prior to commencement of the bankruptcy proceeding, (ii) to the extent such
rents are used by the borrower to maintain the mortgaged property, or for other
court authorized expenses, or (iii) to the extent other collateral may be
substituted for the rents.

         To the extent a mortgagor's ability to make payment on a mortgage loan
is dependent on payments under a lease of the related property, such ability
may be impaired by the commencement of a bankruptcy proceeding relating to a
lessee under such lease. Under the Bankruptcy Code, the filing of a petition in
bankruptcy by or on behalf of a lessee results in a stay in bankruptcy against
the commencement or continuation of any state court proceeding for past due
rent, for accelerated rent, for damages or for a summary eviction order with
respect to a default under the lease that occurred prior to the filing of the
lessee's petition.

         In addition, federal bankruptcy law generally provides that a trustee
or debtor in possession in a bankruptcy or reorganization case under the
Bankruptcy Code may, subject to approval of the court, (a) assume the lease and
retain it or assign it to a third party or (b) reject the lease. If the lease
is assumed, the trustee or debtor in possession (or assignee, if applicable)
must cure any defaults under the lease, compensate the lessor for its losses
and provide the lessor with "adequate assurance" of future performance. Such
remedies may be insufficient, however, as the lessor may be forced to continue
under the lease with a lessee that is a poor credit risk or an unfamiliar
tenant if the lease was assigned, and any assurances provided to the lessor
may, in fact, be inadequate. Furthermore, there is likely to be a period of
time between the date upon which a lessee files a bankruptcy petition and the
date upon which the lease is assumed or rejected. Although the lessee is
obligated to make all lease payments currently with respect to the
post-petition period, there is a risk that such payments will not be made due
to the lessee's poor financial condition. If the lease is rejected, the lessor
will be treated as an unsecured creditor with 


                                      39
<PAGE>

respect to its claim for damages for termination of the lease and the mortgagor
must relet the mortgaged property before the flow of lease payments will
recommence. In addition, pursuant to Section 502(b)(6) of the Bankruptcy Code,
a lessor's damages for lease rejection are limited.

         In a bankruptcy or similar proceeding action may be taken seeking the
recovery as a preferential transfer of any payments made by the mortgagor under
the related Mortgage Loan to the Trust Fund. 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.
Whether any particular payment would be protected depends upon the facts
specific to a particular transaction.

ENFORCEABILITY OF CERTAIN PROVISIONS

Prepayment Provisions

         Courts generally enforce claims requiring prepayment fees unless
enforcement would be unconscionable. However, 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 mortgage loan may not be enforceable against the mortgagor.
Some state statutory provisions may also treat certain prepayment fees as
usurious if in excess of statutory limits. See "--Applicability of Usury Laws."
Some of the Mortgage Loans included in the Mortgage Pool for a Series may not
require the payment of specified fees as a condition to prepayment or such
requirements have expired, and to the extent some Mortgage Loans do require
such fees, such fees generally may not deter Borrowers from prepaying their
Mortgage Loans.

Due-on-Sale Provisions

         The enforceability of due-on-sale clauses has been the subject of
legislation or litigation in many states, and in some cases, typically
involving single family residential mortgage transactions, their enforceability
has been limited or denied. In any event, the Garn-St Germain Depository
Institutions Act of 1982 (the "Garn-St Germain Act") preempts state
constitutional, statutory and case law that prohibits the enforcement of
due-on-sale clauses and permits lenders to enforce these clauses in accordance
with their terms, subject to certain exceptions. As a result, due-on-sale
clauses have become generally enforceable except in those states whose
legislatures exercised their authority to regulate the enforceability of such
clauses with respect to mortgage loans that were (i) originated or assumed
during the "window period" under the Garn-St Germain Act, which ended in all
cases not later than October 15, 1982, and (ii) originated by lenders other
than national banks, federal savings institutions and federal credit unions.
FHLMC has taken the position in its published mortgage servicing standards
that, out of a total of eleven "window period states," five states (Arizona,
Michigan, Minnesota, New Mexico and Utah) have enacted statutes extending, on
various terms and for varying periods, the prohibition on enforcement of
due-on-sale clauses with respect to certain categories of window period loans.
Also, the Garn-St Germain Act does "encourage" lenders to permit assumption of
loans at the original rate of interest or at some other rate less than the
average of the original rate and the market rates.

         The Agreement for each Series will provide that if any Mortgage Loan
contains a provision in the nature of a "due-on-sale" clause, which by its
terms provides that: (i) such Mortgage Loan shall (or may at the mortgagee's
option) become due and payable upon the sale or other transfer of an interest
in the related Mortgaged Property; or (ii) such Mortgage Loan may not be
assumed without the consent of the related mortgagee in connection with any
such sale or other transfer, then, for so long as such Mortgage 


                                      40
<PAGE>

Loan is included in the Trust Fund, the Master Servicer, on behalf of the
Trustee, shall take such actions as it deems to be in the best interest of the
Certificateholders in accordance with the servicing standard set forth in the
Agreement, and may waive or enforce any due-on-sale clause contained in the
related Note or Mortgage.

         In addition, under federal bankruptcy law, due-on-sale clauses may not
be enforceable in bankruptcy proceedings and may, under certain circumstances,
be eliminated in any modified mortgage resulting from such bankruptcy
proceeding.

Acceleration on Default

         Some of the Mortgage Loans included in the Mortgage Pool for a Series
will include a "debt-acceleration" clause, which permits the lender to
accelerate the full debt upon a monetary or nonmonetary default of the
Borrower. The courts of all states will enforce clauses providing for
acceleration in the event of a material payment default after giving effect to
any appropriate notices. The courts of any state, however, may refuse to permit
foreclosure of a mortgage or deed of trust when an acceleration of the
indebtedness would be inequitable or unjust or the circumstances would render
the acceleration unconscionable. Furthermore, in some states, the Borrower may
avoid foreclosure and reinstate an accelerated loan by paying only the
defaulted amounts and the costs and attorneys' fees incurred by the lender in
collecting such defaulted payments.

         State courts also are known to apply various legal and equitable
principles to avoid enforcement of the forfeiture provisions of Installment
Contracts. For example, a lender's practice of accepting late payments from the
borrower may be deemed a waiver of the forfeiture clause. State courts also may
impose equitable grace periods for payment of arrearages or otherwise permit
reinstatement of the contract following a default. Not infrequently, if a
borrower under an Installment Contract has significant equity in the property,
equitable principles will be applied to reform or reinstate the contract or to
permit the borrower to share the proceeds upon a foreclosure sale of the
property if the sale price exceeds the debt.

Soldiers' and Sailors' Relief Act

         Under the terms of the Soldiers' and Sailors' Civil Relief Act of
1940, as amended (the "Relief Act"), a Borrower who enters military service
after the origination of such Borrower's Mortgage Loan (including a Borrower
who is a member of the National Guard or is in reserve status at the time of
the origination of the Mortgage Loan and is later called to active duty) may
not be charged interest (including fees and charges) above an annual rate of 6%
during the period of such Borrower's active duty status, unless a court orders
otherwise upon application of the lender. Any shortfall in interest collections
resulting from the application of the Relief Act, to the extent not covered by
any applicable Enhancements, could result in losses to the Holders of the
Certificates. 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 later called to active duty) after origination of the
related Mortgage Loan, no information can be provided as to the number of
Mortgage Loans that may be affected by the Relief Act. Some of the Mortgaged
Properties relating to Mortgage Loans included in the Mortgage Pool for a
Series may be owned by Borrowers who are individuals. In addition, the Relief
Act imposes limitations which would impair the ability of the Master Servicer
to foreclose on an affected Mortgage Loan during the Borrower's period of
active duty status and, under certain circumstances, during an additional three
months thereafter. Thus, in the event that such a Mortgage Loan goes into
default, there may be delays and losses occasioned by the inability to realize
upon the Mortgage Property in a timely fashion.



                                      41
<PAGE>

APPLICABILITY OF USURY LAWS

         State and federal usury laws limit the interest that lenders are
entitled to receive on a mortgage loan. In determining whether a given
transaction is usurious, courts may include charges in the form of "points" and
"fees" as "interest," but may exclude payments in the form of "reimbursement of
foreclosure expenses" or other charges found to be distinct from "interest."
If, however, the amount charged for the use of the money loaned is found to
exceed a statutorily established maximum rate, the form employed and the degree
of overcharge are both immaterial. Statutes differ in their provision as to the
consequences of a usurious loan. One group of statutes requires the lender to
forfeit the interest above the applicable limit or imposes a specified penalty.
Under this statutory scheme, the borrower may have the recorded mortgage or
deed of trust cancelled upon paying its debt with lawful interest, or the
lender may foreclose, but only for the debt plus lawful interest. A second
group of statutes is more severe. A violation of this type of usury law results
in the invalidation of the transaction, thereby permitting the borrower to have
the recorded mortgage or deed of trust cancelled without any payment and
prohibiting the lender from foreclosing.

         Under the Agreement, a representation and warranty will be made to the
effect that the Mortgage Loans included in a given Trust Fund complied at
origination with applicable laws, including usury laws. If this representation
and warranty is breached with respect to any Mortgage Loan in a manner that
materially and adversely affects the interests of Certificateholders, a
Substitute Mortgage Loan will be substituted for such Mortgage Loan or such
Mortgage Loan will be repurchased in accordance with the applicable Agreement.
See "THE MORTGAGE POOLS--Representations and Warranties."

         The Agreement for each Series will provide that the Master Servicer
not charge interest in excess of that permitted under any applicable state and
federal usury laws, notwithstanding that the applicable Note may provide for a
higher rate.

ALTERNATIVE MORTGAGE INSTRUMENTS

         Alternative mortgage instruments, including adjustable rate mortgage
loans, originated by non-federally chartered lenders have historically been
subjected to a variety of restrictions. Such restrictions differed from state
to state, resulting in difficulties in determining whether a particular
alternative mortgage instrument originated by a state-chartered lender was in
compliance with applicable law. These difficulties were alleviated
substantially as a result of the enactment of Title VIII of the Garn-St Germain
Act ("Title VIII"). Title VIII provides that, notwithstanding any state law to
the contrary, state-chartered banks may originate alternative mortgage
instruments in accordance with regulations promulgated by the Comptroller of
the Currency with respect to origination of alternative mortgage instruments by
national banks, state-chartered credit unions may originate alternative
mortgage instruments in accordance with regulations promulgated by the National
Credit Union Administration (the "NCUA") with respect to origination of
alternative mortgage instruments by federal credit unions, and all other
non-federally chartered housing creditors, including state-chartered savings
and loan associations, state-chartered savings banks and mortgage banking
companies, may originate alternative mortgage instruments in accordance with
the regulations promulgated by the Federal Home Loan Bank Board (now the Office
of Thrift Supervision) with respect to origination of alternative mortgage
instruments by federal savings and loan associations. Title VIII provides that
any state may reject applicability of the provision 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.



                                      42
<PAGE>

LEASES AND RENTS

         Some of the Mortgage Loans included in the Mortgage Pool for a Series
may be secured by an assignment of leases (each, a "Lease") and rents of one or
more lessees (each, a "Lessee"), either through a separate document of
assignment or as incorporated in the mortgage. Under such assignments, the
Borrower under the mortgage loan typically assigns its right, title and
interest as landlord under each lease and the income derived therefrom to the
lender, while retaining a license to collect the rents for so long as there is
no default under the mortgage loan documentation. The manner of perfecting the
lender's interest in rents may depend on whether the borrower's assignment was
absolute or one granted as security for the loan. Failure to properly perfect
the lender's interest in rents may result in the loss of a substantial pool of
funds which could otherwise serve as a source of repayment for the loan. In the
event the Borrower defaults, the license terminates and the lender may be
entitled to collect rents. Some state laws may require that to perfect its
interest in rents, the lender must take possession of the property and/or
obtain judicial appointment of a receiver before becoming entitled to collect
the rents. Lenders that actually take possession of the property, however, may
incur potentially substantial risks attendant to being a mortgagee in
possession. Such risks include liability for environmental clean-up costs and
other risks inherent to property ownership. In addition, if bankruptcy or
similar proceedings are commenced by or in respect of the borrower, the
lender's ability to collect the rents may be adversely affected. In the event
of borrower default, the amount of rent the lender is able to collect from the
tenants can significantly affect the value of the lender's security interest.

SECONDARY FINANCING; DUE-ON-ENCUMBRANCE PROVISIONS

         Some of the Mortgage Loans included in the Mortgage Pool for a Series
may not restrict secondary financing, thereby permitting the Borrower to use
the Mortgaged Property as security for one or more additional loans. Some of
the Mortgage Loans may preclude secondary financing (often by permitting the
first lender to accelerate the maturity of its loan if the Borrower further
encumbers the Mortgaged Property) or may require the consent of the senior
lender to any junior or substitute financing; however, such provisions may be
unenforceable in certain jurisdictions under certain circumstances. The
Agreement for each Series will provide that if any Mortgage Loan contains a
provision in the nature of a "due-on-encumbrance" clause, which by its terms:
(i) provides that such Mortgage Loan shall (or may at the mortgagee's option)
become due and payable upon the creation of any lien or other encumbrance on
the related Mortgaged Property; or (ii) requires the consent of the related
mortgagee to the creation of any such lien or other encumbrance on the related
Mortgaged Property, then for so long as such Mortgage Loan is included in a
given Trust Fund, the Master Servicer or, if such Mortgage Loan is a Specially
Serviced Mortgage Loan, the Special Servicer, if any, on behalf of such Trust
Fund, shall exercise (or decline to exercise) any right it may have as the
mortgagee of record with respect to such Mortgage Loan (x) to accelerate the
payments thereon, or (y) to withhold its consent to the creation of any such
lien or other encumbrance, in a manner consistent with the servicing standard
set forth in the Agreement.

         Where the Borrower encumbers the Mortgaged Property with one or more
junior liens, the senior lender is subject to additional risk. First, the
Borrower may have difficulty servicing and repaying multiple loans. Second,
acts of the senior lender which 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 Borrower 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
prejudiced or the Borrower is additionally burdened. Third, if the Borrower
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, delay and in certain
circumstances even prevent the taking of action by the senior lender. Fourth,
the bankruptcy of a junior lender may operate to stay foreclosure or similar
proceedings by the senior lender.



                                      43
<PAGE>

CERTAIN LAWS AND REGULATIONS

         The Mortgaged Properties will be subject to compliance with various
federal, state and local statutes and regulations. Failure to comply (together
with an inability to remedy any such failure) could result in material
diminution in the value of a Mortgaged Property which could, together with the
possibility of limited alternative uses for a particular Mortgaged Property
(i.e., a nursing or convalescent home or hospital), result in a failure to
realize the full principal amount of the related Mortgage Loan.

TYPE OF MORTGAGED PROPERTY

         The lender may be subject to additional risk depending upon the type
and use of the Mortgaged Property in question. For instance, Mortgaged
Properties which are hospitals, nursing homes or convalescent homes may present
special risks to lenders in large part due to significant governmental
regulation of the operation, maintenance, control and financing of health care
institutions. Mortgages on Mortgaged Properties which are owned by the Borrower
under a condominium form of ownership are subject to the declaration, by-laws
and other rules and regulations of the condominium association. Mortgaged
Properties which are hotels or motels may present additional risk to the lender
in that: (i) hotels and motels are typically operated pursuant to franchise,
management and operating agreements which may be terminable by the operator;
and (ii) the transferability of the hotel's operating, liquor and other
licenses to the entity acquiring the hotel either through purchase or
foreclosure is subject to the vagaries of local law requirements. In addition,
Mortgaged Properties which are multifamily residential properties or
cooperatively owned multifamily properties may be subject to rent control laws,
which could impact the future cash flows of such properties.

AMERICANS WITH DISABILITIES ACT

         Under Title III of the Americans with Disabilities Act of 1990 and
rules promulgated thereunder (collectively, the "ADA"), in order to protect
individuals with disabilities, owners of public accommodations (such as hotels,
restaurants, shopping centers, hospitals, schools and social service center
establishments) must remove architectural and communication barriers which are
structural in nature from existing places of public accommodation to the extent
"readily achievable." In addition, under the ADA, alterations to a place of
public accommodation or a commercial facility are to be made so that, to the
maximum extent feasible, such altered portions are readily accessible to and
usable by disabled individuals. The "readily achievable" standard takes into
account, among other factors, the financial resources of the affected site,
owner, landlord or other applicable Person. In addition to imposing a possible
financial burden on the borrower in its capacity as owner or landlord, the ADA
may also impose such requirements on a foreclosing lender who succeeds to the
interest of the Borrower as owner or landlord. Furthermore, since the "readily
achievable" standard may vary depending on the financial condition of the owner
or landlord, a foreclosing lender who is financially more capable than the
Borrower of complying with the requirements of the ADA may be subject to more
stringent requirements than those to which the Borrower is subject.


                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

GENERAL

         The following is a summary of certain anticipated federal income tax
consequences of the purchase, ownership, and disposition of the Certificates.
The summary is based upon the provisions of the Code, the regulations
promulgated thereunder, including, where applicable, proposed regulations, and
the judicial and administrative rulings and decisions now in effect, all of
which are subject to change or 


                                      44
<PAGE>

possible differing interpretations. The statutory provisions, regulations, and
interpretations on which this summary is based are subject to change, and such
change could apply retroactively.

         As used herein, a "U.S. Person" means a beneficial owner of a
Certificate that is for United States federal income tax purposes (i) a citizen
or resident of the United States, (ii) a corporation or a partnership
(including an entity treated as a corporation or partnership for federal income
tax purposes) 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), (iii) an
estate whose income is subject to United States federal income tax regardless
of its source, or (iv) a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States persons have the authority to control all substantial
decisions of the trust. Certain trusts not described in clause (iv) above in
existence on August 20, 1996 that elect to be treated as a United States Person
will also be a U.S.
Person.

         The summary does not purport to deal with all aspects of federal
income taxation that may affect particular investors in light of their
individual circumstances, nor with certain types of investors subject to
special treatment under the federal income tax laws. This summary focuses
primarily upon investors who will hold Certificates as "capital assets"
(generally, property held for investment) within the meaning of Section 1221 of
the Code, but much of the discussion is applicable to other investors as well.
Potential purchasers of Certificates are advised to consult their own tax
advisers concerning the federal, state or local tax consequences to them of the
purchase, holding and disposition of Certificates.

TAXATION OF THE REMIC AND ITS HOLDERS

         General. In the opinion of Brown & Wood LLP, Cadwalader, Wickersham &
Taft or Orrick, Herrington & Sutcliffe LLP (as specified in the related
Prospectus Supplement), special counsel to the Depositor, if a REMIC election
is made with respect to a Series of Certificates, then the arrangement by which
the Certificates of that Series are issued will be treated as one or more
REMICs as long as all of the provisions of the applicable Agreement are
complied with and the statutory and regulatory requirements are satisfied.
Certificates will be designated as "Regular Interests" or "Residual Interests"
in the REMICs, as specified in the related Prospectus Supplement. The opinion
of special counsel may in certain cases be based on representations of the
Depositor or other persons.

         If a REMIC election is made with respect to a Series of Certificates,
(i) Certificates held by a domestic building and loan association will
constitute "a regular or a residual interest in a REMIC" within the meaning of
Code Section 7701(a)(19)(C)(xi) (assuming that at least 95% of the REMIC's
assets consist of cash, government securities, "loans secured by an interest in
real property," and other types of assets described in Code Section
7701(a)(19)(C) (except that if the underlying Mortgage Loans are not
residential Mortgage Loans, the Certificates will not so qualify)); and (ii)
Certificates held by a real estate investment trust will constitute "real
estate assets" within the meaning of Code Section 856(c)(4)(A), and income with
respect to the Certificates will be considered "interest on obligations secured
by mortgages on real property or on interests in real property" within the
meaning of Code Section 856(c)(3)(B) (assuming, for both purposes, that at
least 95% of the REMIC's assets are qualifying assets). If less than 95% of the
REMIC's assets consist of assets described in (i) or (ii) above, then a
Certificate will qualify for the tax treatment described in (i) or ii) in the
proportion that such REMIC assets are qualifying assets.

         It is possible that various reserves or funds will reduce the
proportion of REMIC assets which qualify under the standards described above.

TAXATION OF REGULAR INTERESTS

         Interest and Acquisition Discount. Certificates representing Regular
Interests in a REMIC ("Regular Interest Certificates") are generally taxable to
Holders in the same manner as evidences of indebtedness issued by the REMIC.
Stated interest on the Regular Interest Certificates will be taxable as
ordinary income and taken into account using the accrual method of accounting,
regardless of the Certificateholder's normal accounting method. Reports will be
made annually to the Internal Revenue Service (the "IRS") and to Holders of
Regular Interest Certificates that are not excepted from the reporting
requirements regarding amounts treated as interest (including accrual of
original issue discount) on Regular Interest Certificates.

         Certificates on which interest is not paid currently ("Compound
Interest Certificates") will, and certain of the other Certificates
constituting Regular Interests may, be issued with original issue discount
("OID") within the meaning of Code Section 1273. Rules governing OID are set
forth in Sections 1271-1275 of the Code (the "OID Regulations"). The discussion
herein is based in part on the OID Regulations. Moreover, although the Code
contains specific provisions governing the calculation of OID on securities,
such as the Certificates, on which principal is required to be prepaid based on
prepayments of the underlying assets, regulations interpreting those provisions
have not yet been issued.

         In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Regular Interest Certificate and its issue
price. A Holder of a Regular Interest Certificate must include such OID in
gross income as ordinary income as it accrues under a method taking into
account an economic accrual of the discount. In general, OID must be included
in income in advance of the receipt of the cash representing that income. The
amount of OID on a Regular Interest Certificate will be considered to be zero
if it is less than a de minimis amount determined under the Code.

         The issue price of a Regular Interest Certificate of a Class will
generally be the initial offering price at which a substantial amount of the
Certificates in the Class is sold to the public, and will be treated by the
Depositor as including, in addition, the amount paid by the Certificateholder
for accrued interest that relates to a period prior to the issue date of such
Regular Interest Certificate. Under the OID Regulations, the stated redemption
price at maturity is the sum of all payments on the Certificate other than any
"qualified stated interest" payments. Qualified stated interest is interest
that is unconditionally payable at least annually during the entire term of the
Certificate at either (a) a single fixed rate that appropriately takes into
account the length of the interval between payments or (b) the current values
of (i) a single "qualified floating rate" or (ii) a single "objective rate"
(each a "Single Variable Rate"). A "current value" is the value of a variable
rate on any day that is no earlier than three months prior to the first day on
which that value is in effect and no later than one year following that day. A
qualified floating rate is a rate the variations in which reasonably can be
expected to measure contemporaneous variations in the cost of newly borrowed
funds in the currency in which the Regular Interest Certificate is denominated
(e.g., LIBOR). The rules for determining the qualified stated interest payable
with respect to certain variable rate Regular Interest Certificates not bearing
interest at a Single Variable Rate are discussed below under "--Variable Rate
Regular Interests." In the case of the Compound Interest Certificates, Interest
Weighted Certificates, and certain of the other Regular Interest Certificates,
none of the payments under the instrument will be considered qualified stated
interest, and thus the aggregate amount of all payments will be included in the
stated redemption price at maturity. Further, because Certificateholders are
entitled to receive interest only to the extent that payments are made on the
Mortgage Loans, interest might not be considered to be "unconditionally
payable." In that case, none of the Regular Interest Certificates will have
qualified stated interest.

         The Holder of a Regular Interest Certificate issued with OID must
include in gross income, for all days during its taxable year on which it holds
such Regular Interest Certificate, the sum of the "daily 


                                      46
<PAGE>

portions" of such OID. Under Code Section 1272(a)(6), the amount of OID to be
included in income by a Holder of a debt instrument, such as a Regular Interest
Certificate, that is subject to acceleration due to prepayments on other debt
obligations securing such instruments, is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
"Prepayment Assumption"). The amount of OID includible in income by a Holder
will be computed by allocating to each day during a taxable year a pro-rata
portion of the OID that accrued during the relevant accrual period. The amount
of OID that will accrue during an accrual period (generally the period between
interest payments or compounding dates) is the excess (if any) of the sum of
(a) the present value of all payments remaining to be made on the Regular
Interest Certificate as of the close of the accrual period and (b) the payments
during the accrual period of amounts included in the stated redemption price of
the Regular Interest Certificate, over the "adjusted issue price" of the
Regular Interest Certificate at the beginning of the accrual period. The
adjusted issue price of a Regular Interest Certificate is the sum of its issue
price plus prior accruals of OID, reduced by the total payments made with
respect to such Regular Interest Certificate in all prior periods, other than
qualified stated interest payments. Code Section 1272(a)(6) requires the
present value of the remaining payments to be determined on the basis of three
factors: (i) the original yield to maturity of the Regular Interest Certificate
(determined on the basis of compounding at the end of each accrual period and
properly adjusted for the length of the accrual period), (ii) events which have
occurred before the end of the accrual period and (iii) the assumption that the
remaining payments will be made in accordance with the original Prepayment
Assumption. The effect of this method would be to increase the portions of OID
required to be included in income by a Certificateholder taking into account
prepayments with respect to the Mortgage Loans at a rate that exceeds the
Prepayment Assumption, and to decrease (but not below zero for any period) the
portions of OID required to be included in income by a Certificateholder taking
into account prepayments with respect to the Mortgage Loans at a rate that is
slower than the Prepayment Assumption. Although OID will be reported to
Certificateholders based on the Prepayment Assumption, no representation is
made to Certificateholders that Mortgage Loans will be prepaid at that rate or
at any other rate.

         Certain classes of Certificates may represent more than one class of
REMIC Regular Interests. Unless the applicable Prospectus Supplement specifies
otherwise, the Trustee intends, based on the OID Regulations, to calculate OID
on such Certificates as if, solely for the purposes of computing OID, the
separate Regular Interests were a single debt instrument.

         A subsequent Holder of a Regular Interest Certificate will also be
required to include OID in gross income, but such a Holder who purchases such
Regular Interest Certificate for an amount that exceeds its adjusted issue
price will be entitled (as will an initial Holder who pays more than a Regular
Interest Certificate's issue price) to offset such OID by comparable economic
accruals of portions of such excess.

         Interest Weighted Certificates. It is not clear how income should be
accrued with respect to Regular Interest Certificates the payments on which
consist solely or primarily of a specified portion of the interest payments on
qualified mortgages held by the REMIC ("Interest Weighted Certificate"). The
Depositor intends to take the position that all of the income derived from an
Interest Weighted Certificate should be treated as OID and that the amount and
rate of accrual of such OID should be calculated by treating the Interest
Weighted Certificate as a Compound Interest Certificate. However, the IRS could
assert that income derived from an Interest Weighted Certificate should be
calculated as if the Interest Weighted Certificate were a Certificate purchased
at a premium equal to the excess of the price paid by such Holder for the
Interest Weighted Certificate over its stated principal amount, if any. Under
this approach, a Holder would be entitled to amortize such premium only if it
has in effect an election under Section 171 of the Code with respect to all
taxable debt instruments held by such holder, as described below.
Alternatively, the IRS could assert that the Interest Weighted Certificate
should be taxable under the contingent debt rules governing certain bonds
issued with contingent principal payments, in which 


                                      47
<PAGE>

case a Holder might recognize income at a slower rate than if the Interest
Weighted Certificate were treated as a Compound Interest Certificate.

         Variable Rate Regular Interests. Regular Interest Certificates bearing
interest at one or more variable rates are subject to certain special rules.
The qualified stated interest payable with respect to certain variable rate
debt instruments not bearing interest at a Single Variable Rate generally is
determined under the OID Regulations by converting such instruments into fixed
rate debt instruments. Instruments qualifying for such treatment generally
include those providing for stated interest at (i) more than one qualified
floating rates, or at (ii) a single fixed rate and (a) one or more qualified
floating rates or (b) a single "qualified inverse floating rate" (each, a
"Multiple Variable Rate"). A qualified inverse floating rate is an objective
rate equal to a fixed rate reduced by a qualified floating rate, the variations
in which can reasonably be expected to inversely reflect contemporaneous
variations in the cost of newly borrowed funds (disregarding permissible rate
caps, floors, governors, and similar restrictions such as are described above).

         Purchasers of Regular Interest Certificates bearing a variable rate of
interest should be aware that there is uncertainty concerning the application
of Code Section 1272(a)(6), and the OID Regulations to such Certificates. In
the absence of other authority, the Depositor intends to be guided by the
provisions of the OID Regulations governing variable rate debt instruments in
adapting the provisions of Code Section 1272(a)(6) to such Certificates for the
purpose of preparing reports furnished to the IRS and Certificateholders. In
that regard, in determining OID with respect to Regular Interest Certificates
bearing interest at a Single Variable Rate, (a) all stated interest with
respect to a Regular Interest Certificate is treated as qualified stated
interest and (b) the amount and accrual of OID, if any, is determined under the
OID rules applicable to fixed rate debt instruments discussed above by assuming
that the Single Variable Rate is a fixed rate equal to (i) in the case of a
qualified floating rate or qualified inverse floating rate, the issue date
value of the rate, or (ii) in the case of any other objective rate, a fixed
rate that reflects the yield that is reasonably expected for the Regular
Interest Certificate. Interest and OID attributable to Regular Interest
Certificates bearing interest at a Multiple Variable Rate similarly will be
taken into account under a methodology that converts the Certificate into an
equivalent fixed rate debt instrument. However, in determining the amount and
accrual of OID, the assumed fixed rates are (a) for each qualified floating
rate, the value of each such rate as of the issue date (with appropriate
adjustment for any differences in intervals between interest adjustment dates),
(b) for a qualified inverse floating rate, the value of the rate as of the
issue date, and (c) for any other objective rate, the fixed rate that reflects
the yield that is reasonably expected for the Certificate. In the case of a
Certificate that provides for stated interest at a fixed rate in one or more
accrual periods and either one or more qualified floating rates or a qualified
inverse floating rate in other accrual periods, the fixed rate is initially
converted into a qualified floating rate (or a qualified inverse floating rate,
if the Certificate provides for a qualified inverse floating rate). The
qualified floating rate or qualified inverse floating rate that replaces the
fixed rate must be such that the fair market value of the Regular Interest
Certificate as of its issue date is approximately the same as the fair market
value of an otherwise identical debt instrument that provides for either the
qualified floating rate or the qualified inverse floating rate. Subsequent to
converting the fixed rate into either a qualified floating rate or a qualified
inverse floating rate, the Regular Interest Certificate is then converted into
an equivalent fixed rate debt instrument in the manner described above. If the
interest paid or accrued with respect to a Single Variable Rate or Multiple
Variable Rate Certificate during an accrual period differs from the assumed
fixed interest rate, such difference will be an adjustment (to interest or OID,
as applicable) to the Certificateholder's taxable income for the taxable period
or periods to which such difference relates.

         Purchasers of Certificates bearing a variable rate of interest should
be aware that the provisions of the OID Regulations governing variable rate
debt instruments are limited in scope and may not apply to some Regular
Interest Certificates having variable rates. If such a Certificate is not
subject to the 


                                      48
<PAGE>

provisions of the OID Regulations governing variable rate debt instruments, it
may be subject to the Contingent Regulations described below.

         In June 1996, the Internal Revenue Service (the "IRS") issued OID
Regulations (the "Contingent Regulations") governing the calculation of OID on
instruments having contingent interest payments. In general, the Contingent
Regulations would cause the timing and character of income, gain or loss
reported on a contingent payment debt instrument to substantially differ from
the timing and character of income, gain or loss reported on a contingent
payment debt instrument under general principles of current United States
Federal income tax law. Specifically, the Contingent Regulations generally
require a U.S. Person that is a holder of such an instrument to include future
contingent and noncontingent interest payments in income as such interest
accrues based upon a projected payment schedule. Moreover, in general, under
the Contingent Regulations, any gain recognized by a U.S. Person on the sale,
exchange, or retirement of a contingent payment debt instrument will be treated
as ordinary income and all or a portion of any loss realized could be treated
as ordinary loss as opposed to capital loss (depending upon the circumstances).
The Contingent Regulations apply to debt instruments issued on or after August
13, 1996. Prospective purchasers of variable rate Regular Interest Certificates
should consult their tax advisers concerning the appropriate tax treatment of
such Certificates.

         The Contingent Regulations specifically do not apply for purposes of
calculating OID on debt instruments subject to Code Section 1272(a)(6).
Additionally, the OID Regulations do not contain provisions specifically
interpreting Code Section 1272(a)(6). Until the Treasury issues guidance to the
contrary, the Trustee intends to base its computation on Code Section
1272(a)(6) and the OID Regulations as described in this Prospectus. However,
because no regulatory guidance currently exists under Code Section 1272(a)(6),
there can be no assurance that such methodology represents the correct manner
of calculating OID.

         Market Discount and Premium. A purchaser of a Regular Interest
Certificate may also be subject to the market discount rules of the Code. Such
purchaser generally will be required to recognize accrued market discount as
ordinary income as payments of principal are received on such Regular Interest
Certificate, or upon sale or exchange of the Regular Interest Certificate. In
general terms, until regulations are promulgated, market discount may be
treated as accruing, at the election of the Holder, either (i) under a constant
yield method, taking into account the Prepayment Assumption, or (ii) in
proportion to accruals of OID (or, if there is no OID, in proportion to
accruals of stated interest). A Holder of a Regular Interest Certificate having
market discount may also be required to defer a portion of the interest
deductions attributable to any indebtedness incurred or continued to purchase
or carry the Regular Interest Certificate. As an alternative to the inclusion
of market discount in income on the foregoing basis, the Holder may elect to
include such market discount in income currently as it accrues on all market
discount instruments acquired by such Holder in that taxable year or
thereafter, in which case the interest deferral rule will not apply.

         A Holder who purchases a Regular Interest Certificate (other than an
Interest Weighted Certificate, to the extent described above) at a cost greater
than its stated redemption price at maturity, generally will be considered to
have purchased the Certificate at a premium, which it may elect to amortize as
an offset to interest income on such Certificate (and not as a separate
deduction item) on a constant yield method. The legislative history of the Tax
Reform Act of 1986 (the "1986 Act") indicates that premium is to be accrued in
the same manner as market discount. Accordingly, it appears that the accrual of
premium on a Regular Interest Certificate will be calculated using the
prepayment assumption used in pricing such Regular Interest Certificate. If a
Holder makes an election to amortize premium on a Certificate, such election
will apply to all taxable debt instruments (including all REMIC Regular
Interests) held by the Holder at the beginning of the taxable year in which the
election is made, and to all taxable debt instruments acquired thereafter by
such Holder, and will be irrevocable without the consent 


                                      49
<PAGE>

of the IRS. Purchasers who pay a premium for Regular Interest Certificates
should consult their tax advisers regarding the election to amortize premium
and the method to be employed.

         Interest Election. Under the OID Regulations, holders of Regular
Interest Certificates generally may elect to include all accrued interest on a
Regular Interest Certificate in gross income using the constant yield to
maturity method. For purposes of this election, interest includes stated
interest, original issue discount, de minimis original issue discount, market
discount, de minimis market discount and unstated interest, as adjusted by any
premium. If a holder of a Regular Interest Certificate makes such an election
and (i) the Regular Interest Certificate has amortizable bond premium, the
holder is deemed to have made an election to amortize bond premium with respect
to all debt instruments having amortizable bond premium that such
Certificateholder owns or acquires, or (ii) the Regular Interest Certificate
has market discount, the holder is deemed to have made an election to include
market discount in income currently for all debt instruments having market
discount acquired during the year of the election or thereafter. See "--Market
Discount and Premium" above. A holder of a Regular Interest Certificate should
consult its tax adviser before making this election.

         Treatment of Subordinate Certificates. As described above under
"ENHANCEMENT -- Subordinate Certificates," certain Series of Certificates may
contain one or more Classes of Subordinate Certificates. Holders of Subordinate
Certificates will be required to report income with respect to such
Certificates on the accrual method without giving effect to delays and
reductions in distributions attributable to defaults or delinquencies on any
Mortgage Loans, except possibly to the extent that it can be established that
such amounts are uncollectible. As a result, the amount of income reported by a
Holder of a Subordinate Certificate in any period could significantly exceed
the amount of cash distributed to such Holder in that period.

         Although not entirely clear, it appears that a corporate Holder
generally should be allowed to deduct as an ordinary loss any loss sustained on
account of partial or complete worthlessness of a Subordinate Certificate.
Although similarly unclear, a noncorporate Holder generally should be allowed
to deduct as a short-term capital loss any loss sustained on account of
complete worthlessness of a Subordinate Certificate. A noncorporate Holder
alternatively may be allowed such a loss deduction as the principal balance of
a Subordinate Certificate is reduced by reason of realized losses resulting
from liquidated Mortgage Loans; however, the IRS could contend that a
noncorporate Holder should be allowed such losses only after all Mortgage Loans
in the Trust Fund have been liquidated or the Subordinate Certificates
otherwise have been retired. Special rules are applicable to banks and thrift
institutions, including rules regarding reserves for bad debts. Holders of
Subordinate Certificates should consult their own tax advisers regarding the
appropriate timing, character and amount of any loss sustained with respect to
Subordinate Certificates.



REMIC EXPENSES

         As a general rule, all of the expenses of a REMIC will be taken into
account by Holders of the Residual Interest Certificates. In the case of
a"single-class REMIC," however, the expenses will be allocated, under temporary
Treasury regulations, among the Holders of the Regular Interest Certificates
and the Holders of the Residual Interest Certificates on a daily basis in
proportion to the relative amounts of income accruing to each Certificateholder
on that day. In the case of a Regular Interest Certificateholder who is an
individual or a "pass-through interest holder"(including certain pass-through
entities but not including real estate investment trusts), such expenses will
be deductible only to the extent that such expenses, plus other "miscellaneous
itemized deductions" of the Certificateholder, exceed 2% of such
Certificateholder's adjusted gross income. In addition, itemized deductions are
further restrected by other Sections of theCode. The disallowance of some or
all of these deductions may have a significant impact on the yield of the
Regular Interest Certificate to such a Holder. In general terms, a single-class


                                      50
<PAGE>

REMIC is one that either (i) would qualify, under existing Treasury
regulations, as a grantor trust if it were not a REMIC (treating all interests
as ownership interests, even if they would be classified as debt for federal
income tax purposes) or (ii) is similar to such a trust and is structured with
the principal purpose of avoiding the single-class REMIC rules.

SALE OR EXCHANGE OF REMIC REGULAR INTEREST CERTIFICATES

         A Regular Interest Certificateholder's tax basis in its Regular
Interest Certificate is the price such Holder pays for a Certificate, plus
amounts of OID or market discount included in income and reduced by any
payments received (other than qualified stated interest payments) and any
amortized premium. Gain or loss recognized on a sale, exchange, or redemption
of a Regular Interest Certificate, measured by the difference between the
amount realized and the Regular Interest Certificate's basis as so adjusted,
will generally be capital gain or loss, assuming that the Regular Interest
Certificate is held as a capital asset. If, however, a Certificateholder is a
bank, thrift, or similar institution described in Section 582 of the Code, gain
or loss realized on the sale or exchange of a Certificate will be taxable as
ordinary income or loss. In addition, gain from the disposition of a Regular
Interest Certificate that might otherwise be capital gain will be treated as
ordinary income to the extent of the excess, if any, of (i) the amount that
would have been includible in the Holder's income if the yield on such Regular
Interest Certificate had equaled 110% of the applicable federal rate as of the
beginning of such Holder's holding period, over (ii) the amount of ordinary
income actually recognized by the Holder with respect to such Regular Interest
Certificate.

TAXATION OF THE REMIC

         General. Although a REMIC is a separate entity for federal income tax
purposes, a REMIC is not generally subject to entity-level taxation. Rather,
except in the case of a "single-class REMIC," the taxable income or net loss of
a REMIC is taken into account by the Holders of Residual Interests. The Regular
Interests are generally taxable as debt of the REMIC.

         Calculation of REMIC Income. The taxable income or net loss of a REMIC
is determined under an accrual method of accounting and in the same manner as
in the case of an individual, with certain adjustments. In general, the taxable
income or net loss will be the difference between (i) the gross income produced
by the REMIC's assets, including stated interest and any OID or market discount
on loans and other assets, and (ii) deductions, including stated interest and
OID accrued on Regular Interest Certificates, amortization of any premium with
respect to loans, and servicing fees and other expenses of the REMIC. A Holder
of a Residual Interest Certificate that is an individual or a "pass-through
interest holder" (including certain pass-through entities, but not including
real estate investment trusts) will be unable to deduct servicing fees payable
on the loans or other administrative expenses of the REMIC for a given taxable
year to the extent that such expenses, when aggregated with the Residual
Interest Certificateholder's other miscellaneous itemized deductions for that
year, do not exceed two percent of such Holder's adjusted gross income.

         For purposes of computing its taxable income or net loss, the REMIC
should have an initial aggregate tax basis in its assets equal to the aggregate
fair market value of the Regular Interests and the Residual Interests on the
Startup Day (generally, the day that the interests are issued). That aggregate
basis will be allocated among the assets of the REMIC in proportion to their
respective fair market values.

         The OID provisions of the Code apply to loans of individuals
originated on or after March 2, 1984, and the market discount provisions apply
to all loans. Subject to possible application of the de minimis rules, the
method of accrual by the REMIC of OID or market discount income on such loans
will be equivalent to the method under which Holders of Regular Interest
Certificates accrue OID (i.e., under 


                                      51
<PAGE>

the constant yield method taking into account the Prepayment Assumption). The
REMIC will deduct OID on the Regular Interest Certificates in the same manner
that the Holders of the Certificates include such discount in income, but
without regard to the de minimis rules. See "--Taxation of Regular Interests"
above. However, a REMIC that acquires loans at a market discount must include
such market discount in income currently, as it accrues, on a constant interest
basis.

         To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the life
of the loans (taking into account the Prepayment Assumption) on a constant
yield method. Although the law is somewhat unclear regarding recovery of
premium attributable to loans originated on or before such date, it is possible
that such premium may be recovered in proportion to payments of loan principal.

TAXATION OF HOLDERS OF RESIDUAL INTEREST CERTIFICATES

         The Holder of a Certificate representing a residual interest (a
"Residual Interest Certificate") will take into account the "daily portion" of
the taxable income or net loss of the REMIC for each day during the taxable
year on which such Holder held the Residual Interest Certificate. The daily
portion is determined by allocating to each day in any calendar quarter its
ratable portion of the taxable income or net loss of the REMIC for such
quarter, and by allocating that amount among the Holders (on such day) of the
Residual Interest Certificates in proportion to their respective holdings on
such day.

         Prohibited Transactions and Contributions Tax. The REMIC will be
subject to a 100% tax on any net income derived from a "prohibited
transaction." For this purpose, net income will be calculated without taking
into account any losses from prohibited transactions or any deductions
attributable to any prohibited transaction that resulted in a loss. In general,
prohibited transactions include (i) subject to limited exceptions, the sale or
other disposition of any qualified mortgage transferred to the REMIC; (ii)
subject to a limited exception, the sale or other disposition of a cash flow
investment; (iii) the receipt of any income from assets not permitted to be
held by the REMIC pursuant to the Code; or (iv) the receipt of any fees or
other compensation for services rendered by the REMIC. It is anticipated that a
REMIC will not engage in any prohibited transactions in which it would
recognize a material amount of net income. In addition, subject to a number of
exceptions, a tax is imposed at the rate of 100% on amounts contributed to a
REMIC after the close of the three-month period beginning on the Startup Day.
The Holders of Residual Interest Certificates will generally be responsible for
the payment of any such taxes imposed on the REMIC. To the extent not paid by
such Holders or otherwise, however, such taxes will be paid out of the Trust
Fund and will be allocated pro-rata to all outstanding Classes of Certificates
of such REMIC.

         The Holder of a Residual Interest Certificate must report its
proportionate share of the taxable income of the REMIC whether or not it
receives cash distributions from the REMIC attributable to such income or loss.
The reporting of taxable income without corresponding distributions could
occur, for example, in certain REMICs in which the loans held by the REMIC were
issued or acquired at a discount, since mortgage prepayments cause recognition
of discount income, while the corresponding portion of the prepayment could be
used in whole or in part to make principal payments on REMIC Regular Interests
issued without any discount or at an insubstantial discount. (If this occurs,
it is likely that cash distributions will exceed taxable income in later
years.) Taxable income may also be greater in the earlier years of certain
REMICs as a result of the fact that interest expense deductions, as a
percentage of outstanding principal of REMIC Regular Interest Certificates,
will typically increase over time as lower yielding Certificates are paid,
whereas interest income with respect to loans will generally remain constant
over time as a percentage of loan principal.



                                      52
<PAGE>

         In any event, because the Holder of a Residual Interest is taxed on
the net income of the REMIC, the taxable income derived from a Residual
Interest Certificate in a given taxable year will not be equal to the taxable
income associated with investment in a corporate bond or stripped instrument
having similar cash flow characteristics and pre-tax yield. Therefore, the
after-tax yield on the Residual Interest Certificate may be less than that of
such a bond or instrument.

         Limitation on Losses. The amount of the REMIC's net loss that a Holder
may take into account currently is limited to the Holder's adjusted basis at
the end of the calendar quarter in which such loss arises. A Holder's basis in
a Residual Interest Certificate will initially equal such Holder's purchase
price, and will subsequently be increased by the amount of the REMIC's taxable
income allocated to the Holder, and decreased (but not below zero) by the
amount of distributions made and the amount of the REMIC's net loss allocated
to the Holder. Any disallowed loss may be carried forward indefinitely, but may
be used only to offset income of the REMIC generated by the same REMIC. The
ability of Residual Interest Certificateholders to deduct net losses may be
subject to additional limitations under the Code, as to which such Holders
should consult their tax advisers.

         Distributions. Distributions on a Residual Interest Certificate
(whether at their scheduled times or as a result of prepayments) will generally
not result in any additional taxable income or loss to a Holder of a Residual
Interest Certificate. If the amount of such payment exceeds a Holder's adjusted
basis in the Residual Interest Certificate, however, the Holder will recognize
gain (treated as gain from the sale of the Residual Interest Certificate) to
the extent of such excess.

         Sale or Exchange. A Holder of a Residual Interest Certificate will
recognize gain or loss on the sale or exchange of a Residual Interest
Certificate equal to the difference, if any, between the amount realized and
such Certificateholder's adjusted basis in the Residual Interest Certificate at
the time of such sale or exchange. Any such loss may be a capital loss subject
to limitation; gain which might otherwise be capital may be treated as ordinary
income under certain circumstances. See "--Sal or Exchange of REMIC Regular
Interest Certificates" above. Except to the extent provided in regulations,
which have not yet been issued, any loss upon disposition or a Residual
Interest Certificate will be disallowed if the selling Certificateholder
acquires any residual interest in a REMIC or similar mortgage pool within six
months before or after such disposition.

EXCESS INCLUSIONS

         The portion of a Residual Interest Certificateholder's REMIC taxable
income consisting of "excess inclusion" income may not be offset by other
deductions or losses, including net operating losses, on such
Certificateholder's federal income tax return. If the Holder of a Residual
Interest Certificate is an organization subject to the tax on unrelated
business income imposed by Code Section 511, such Residual Interest
Certificateholder's excess inclusion income will be treated as unrelated
business taxable income of such Certificateholder. In addition, under Treasury
regulations yet to be issued, if a real estate investment trust, a regulated
investment company, a common trust fund, or certain cooperatives were to own a
Residual Interest Certificate, a portion of dividends (or other distributions)
paid by the real estate investment trust (or other entity) would be treated as
excess inclusion income. If a Residual Certificate is owned by a foreign
person, excess inclusion income is subject to tax at a rate of 30%, which rate
may not be reduced by treaty and is not eligible for treatment as "portfolio
interest."

         The excess inclusion portion of a REMIC's income is generally equal to
the excess, if any, of REMIC taxable income for the quarterly period allocable
to a Residual Interest Certificate, over the daily accruals for such quarterly
period of (i) 120% of the long term applicable federal rate on the Startup Day
multiplied by (ii) the adjusted issue price of such Residual Interest
Certificate at the beginning of such quarterly period. The adjusted issue price
of a Residual Interest at the beginning of each calendar quarter


                                      53
<PAGE>

will equal its issue price (calculated in a manner analogous to the
determination of the issue price of a Regular Interest), increased by the
aggregate of the daily accruals for prior calendar quarters, and decreased (but
not below zero) by the amount of loss allocated to a Holder and the amount of
distributions made on the Residual Interest Certificate before the beginning of
the quarter. The long-term federal rate, which is announced monthly by the
Treasury Department, is an interest rate that is based on the average market
yield of outstanding marketable obligations of the United States government
having remaining maturities in excess of nine years.

         In addition, the Small Business Job Protection Act of 1996 provides
three rules for determining the effect on excess inclusions on the alternative
minimum taxable income of a Residual Interest Certificateholder. First,
alternative minimum taxable income for such Residual Interest Certificateholder
is determined without regard to the special rule that taxable income cannot be
less than excess inclusions. Second, a Residual Interest Certificateholder's
alternative minimum taxable income for a tax year cannot be less than excess
inclusions for the year. Third, the amount of any alternative minimum tax net
operating loss deductions must be computed without regard to any excess
inclusions.

         Under the REMIC Regulations, in certain circumstances, transfers of
Residual Certificates may be disregarded. See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES-- Restrictions on Ownership and Transfer of Residual Interest
Certificates" and "--Tax Treatment of Foreign Investors."

RESTRICTIONS ON OWNERSHIP AND TRANSFER OF RESIDUAL INTEREST CERTIFICATES

         As a condition to qualification as a REMIC, reasonable arrangements
must be made to prevent the ownership of a Residual Interest Certificate by any
"Disqualified Organization." Disqualified Organizations include the United
States, any State or political subdivision thereof, any foreign government, any
international organization, or any agency or instrumentality of any of the
foregoing, a rural electric or telephone cooperative described in Section
1381(a)(2)(C) of the Code, or any entity exempt from the tax imposed by
Sections 1-1399 of the Code, if such entity is not subject to tax on its
unrelated business income. Accordingly, the applicable Agreement will prohibit
Disqualified Organizations from owning a Residual Interest Certificate. In
addition, no transfer of a Residual Interest Certificate will be permitted
unless the proposed transferee shall have furnished to the Trustee an affidavit
representing and warranting that it is neither a Disqualified Organization nor
an agent or nominee acting on behalf of a Disqualified Organization.

         If a Residual Interest Certificate is transferred to a Disqualified
Organization (in violation of the restrictions set forth above), a substantial
tax will be imposed on the transferor of such Residual Interest Certificate at
the time of the transfer. In addition, if a Disqualified Organization holds an
interest in a pass-through entity (including, among others, a partnership,
trust, real estate investment trust, regulated investment company, or any
person holding as nominee) that owns a Residual Interest Certificate, the
pass-through entity will be required to pay an annual tax on its allocable
share of the excess inclusion income of the REMIC.

         The Taxpayer Relief Act of 1997 adds provisions to the Code that will
apply to an "electing large partnership." If an electing large partnership
holds a Residual Interest Certificate, 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(e) 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.

         Under the REMIC Regulations, if a Residual Interest Certificate is a
"noneconomic residual interest," as described below, a transfer of a Residual
Interest Certificate to a United States person will be 


                                      54
<PAGE>

disregarded for all Federal tax purposes unless no significant purpose of the
transfer was to impede the assessment or collection of tax. A Residual Interest
Certificate 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 Certificate at least equals the product of the present value
of the anticipated excess inclusions and the highest rate of tax for the year
in which the transfer occurs, and (ii) the transferor reasonably expects that
the transferee will receive distributions from the REMIC at or after the time
at which the taxes accrue on the anticipated excess inclusions in an amount
sufficient to satisfy the accrued taxes. The present value is calculated based
on the Prepayment Assumption, using a discount rate equal to the "applicable
federal rate" at the time of transfer. If a transfer of a Residual Interest is
disregarded, the transferor would be liable for any Federal income tax imposed
upon the taxable income derived by the transferee from the REMIC. A significant
purpose to impede the assessment or collection of tax exists if the transferor,
at the time of transfer, knew or should have known that the transferee would be
unwilling or unable to pay taxes on its share of the taxable income of the
REMIC. A similar type of limitation exists with respect to certain transfers of
residual interests by foreign persons to United States persons. See "CERTAIN
FEDERAL INCOME TAX CONSEQUENCES -- Tax Treatment of Foreign Investors."

ADMINISTRATIVE MATTERS

         The REMIC's books must be maintained on a calendar year basis and the
REMIC must file an annual federal income tax return. The REMIC will also be
subject to the procedural and administrative rules of the Code applicable to
partnerships, including the determination of any adjustments to, among other
things, items of REMIC income, gain, loss, deduction, or credit, by the IRS in
a unified administrative proceeding.

TAX STATUS AS A GRANTOR TRUST

         General. In the opinion of Brown & Wood LLP, Cadwalader, Wickersham &
Taft or Orrick, Herrington & Sutcliffe LLP (as specified in the related
Prospectus Supplement), special counsel to the Depositor, if a REMIC election
is not made with respect to a Series of Certificates, the Trust Fund will be
classified for federal income tax purposes as a grantor trust under Subpart E,
Part 1 of Subchapter J of the Code and not as an association taxable as a
corporation. In some Series ("Pass-Through Certificates"), there will be no
separation of the principal and interest payments on the Mortgage Loans. In
such circumstances, a Certificateholder will be considered to have purchased an
undivided interest in each of the Mortgage Loans. In other cases ("Stripped
Certificates"), sale of the Certificates will produce a separation in the
ownership of the principal payments and interest payments on the Mortgage
Loans.

         Each Certificateholder must report on its federal income tax return
its pro rata share of the gross income derived from the Mortgage Loans (not
reduced by the amount payable as fees to the Trustee and the Master Servicer
and similar fees (collectively, the "Trustee/Master Servicer Fee")), at the
same time and in the same manner as such items would have been reported under
the Certificateholder's tax accounting method had it held its interest in the
Mortgage Loans directly, received directly its share of the amounts received
with respect to the Mortgage Loans, and paid directly its share of the
Trustee/Master Servicer Fees. In the case of Pass-Through Certificates, such
gross income will consist of a pro rata share of all of the income derived from
all of the Mortgage Loans and, in the case of Stripped Certificates, such
income will consist of a pro rata share of the income derived from each
stripped bond or stripped coupon in which the Certificateholder owns an
interest. The Holder of a Certificate will generally be entitled to deduct such
Trustee/Master Servicer Fees under Section 162 or Section 212 of the Code to
the extent that such Trustee/Master Servicer Fees represent "reasonable"
compensation for the services rendered by the Trustee and the Master Servicer.
In the case of a noncorporate holder, however, Trustee/Master Servicer Fees (to
the extent not otherwise disallowed, e.g., because they exceed reasonable
compensation) will be deductible in computing such Holder's regular tax
liability only to the extent that such fees, when added 


                                      55
<PAGE>

to other miscellaneous itemized deductions, exceed 2% of adjusted gross income
and may not be deductible to any extent in computing such Holder's alternative
minimum tax liability. Further, other Sections of Code limit the amount of
itemized deductions otherwise allowable.

         Discount or Premium on Pass-Through Certificates. The Holder's
purchase price of a Pass-Through Certificate is to be allocated among the
Mortgage Loans in proportion to their fair market values, determined as of the
time of purchase of the Certificates. In the typical case, the Trustee believes
it is reasonable for this purpose to treat each Mortgage Loan as having a fair
market value proportional to the share of the aggregate principal balances of
all of the Mortgage Loans that it represents, since the Mortgage Loans, unless
otherwise specified in the applicable Prospectus Supplement, will have a
relatively uniform interest rate and other common characteristics. To the
extent that the portion of the purchase price of a Certificate allocated to a
Mortgage Loan (other than to a right to receive any accrued interest thereon
and any undistributed principal payments) is less than or greater than the
portion of the principal balance of the Mortgage Loan allocable to the
Certificate, the interest in the Mortgage Loan allocable to the Certificate
will be deemed to have been acquired at a discount or premium, respectively.

         The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Mortgage Loan with OID in
excess of a prescribed de minimis amount, a Holder of a Certificate will be
required to report as interest income in each taxable year its share of the
amount of OID that accrues during that year, determined under a constant yield
method by reference to the initial yield to maturity of the Mortgage Loan, in
advance of receipt of the cash attributable to such income and regardless of
the method of federal income tax accounting employed by that Holder. OID with
respect to a Mortgage Loan could arise, for example, by virtue of the financing
of points by the originator of the Mortgage Loan, or by virtue of the charging
of points by the originator of the Mortgage Loan in an amount greater than a
statutory de minimis exception, in circumstances under which the points are not
currently deductible pursuant to applicable Code provisions. However, the Code
provides for a reduction in the amount of OID includible in the income of a
Holder who acquires an obligation after its initial issuance at a price greater
than the sum of the original issue price of the Mortgage Loan and the
previously accrued OID, less prior payments of principal. Accordingly, if the
Mortgage Loans acquired by a Certificateholder are purchased at a price equal
to the then unpaid principal amount of such Mortgage Loans, any OID should be
reduced or eliminated.

         Certificateholders also may be subject to the market discount rules of
Sections 1276-1278 of the Code. A Certificateholder that acquires an interest
in Mortgage Loans with more than a prescribed de minimis amount of "market
discount" (generally, the excess of the principal amount of the Mortgage Loans
over the purchaser's purchase price) will be required under Section 1276 of the
Code to include accrued market discount in income as ordinary income in each
month, but limited to an amount not exceeding the principal payments on the
Mortgage Loans received in that month and, if the Certificates are sold, the
gain realized. Such market discount would accrue in a manner to be provided in
Treasury regulations. The legislative history of the 1986 Act indicates that,
until such regulations are issued, such market discount would in general accrue
either (i) on the basis of a constant interest rate or (ii) in the ratio of (a)
in the case of Mortgage Loans not originally issued with OID, stated interest
payable in the relevant period to total stated interest remaining to be paid at
the beginning of the period, or (b) in the case of Mortgage Loans originally
issued at a discount, OID in the relevant period to total OID remaining to be
paid.

         Section 1277 of the Code provides that, regardless of the origination
date, the excess of interest paid or accrued to purchase or carry a loan with
market discount over interest received on such loan is allowed as a current
deduction only to the extent such excess is greater than the market discount
that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, 


                                      56
<PAGE>

including upon the sale, disposition, or repayment of the loan. A Holder may
elect to include market discount in income currently as it accrues, on all
market discount obligations acquired by such Holder during the taxable year
such election is made and thereafter, in which case the interest deferral rule
discussed above will not apply.

         A Certificateholder who purchases a Certificate at a premium generally
will be deemed to have purchased its interest in the underlying Mortgage Loans
at a premium. A Certificateholder who holds a Certificate as a capital asset
may generally elect under Section 171 of the Code to amortize such premium as
an offset to interest income on the Mortgage Loans (and not as a separate
deduction item) on a constant yield method. The legislative history of the 1986
Act suggests that the same rules that will apply to the accrual of market
discount (described above) will generally also apply in amortizing premium with
respect to Mortgage Loans originated after September 27, 1985. If a Holder
makes an election to amortize premium, such election will apply to all taxable
debt instruments held by such Holder at the beginning of the taxable year in
which the election is made, and to all taxable debt instruments acquired
thereafter by such Holder, and will be irrevocable without the consent of the
IRS. Purchasers who pay a premium for the Certificates should consult their tax
advisers regarding the election to amortize premium and the method to be
employed. Although the law is somewhat unclear regarding recovery of premium
allocable to Mortgage Loans originated before September 28, 1985, it is
possible that such premium may be recovered in proportion to payments of
Mortgage Loan principal.

         Discount or Premium on Stripped Certificates. A Stripped Certificate
may represent a right to receive only a portion of the interest payments on the
Mortgage Loans, a right to receive only principal payments on the Mortgage
Loans, or a right to receive certain payments of both interest and principal.
Certain Stripped Certificates ("Ratio Strip Certificates") may represent a
right to receive differing percentages of both the interest and principal on
each Mortgage Loan. Pursuant to Section 1286 of the Code, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from ownership of the right to receive some or all of the principal
payments results in the creation of "stripped bonds" with respect to principal
payments and "stripped coupons" with respect to interest payments. Section 1286
of the Code applies the OID rules to stripped bonds and stripped coupons. For
purposes of computing OID, a stripped bond or a stripped coupon is treated as a
debt instrument issued on the date that such stripped interest is purchased
with an issue price equal to its purchase price or, if more than one stripped
interest is purchased, the ratable share of the purchase price allocable to
such stripped interest. The Code, OID Regulations and judicial decisions
provide little direct guidance as to how the OID rules are to apply to Stripped
Certificates, although regulations indicate that in determining whether the
portion of the interest on a Mortgage Loan payable to a particular Class of
Certificates is "qualified stated interest," all principal and interest
payments payable to that Class from that Mortgage Loan are taken into account.
Under the method described above for REMIC Regular Interest Certificates (the
"Cash Flow Bond Method"), a prepayment assumption is used and periodic
recalculations are made which take into account with respect to each accrual
period the effect of prepayments during such period. The Code prescribes the
same method for debt instruments "secured by" other debt instruments, the
maturity of which may be affected by prepayments on the underlying debt
instruments. However, the Code does not, absent Treasury regulations, appear
specifically to cover instruments such as the Stripped Certificates which
technically represent ownership interests in the underlying Mortgage Loans,
rather than being debt instruments "secured by" those loans. Nevertheless, it
is believed that the Cash Flow Bond Method is a reasonable method of reporting
income for such Certificates, and it is expected that OID will be reported on
that basis unless otherwise specified in the related Prospectus Supplement. In
applying the calculation to Stripped Certificates, the Trustee will treat all
payments to be received with respect to a Class of Certificates as payments on
a single installment obligation. The IRS could, however, assert that OID must
be calculated separately for each Mortgage Loan underlying a Class of
Certificates.




                                      57
<PAGE>

         Under certain circumstances, if the Mortgage Loans prepay at a rate
faster than the Prepayment Assumption, the use of the Cash Flow Bond Method may
accelerate a Certificateholder's recognition of income. If, however, the
Mortgage Loans prepay at a rate slower that the prepayment assumption, in some
circumstances the use of this method may decelerate a Certificateholder's
recognition of income.

         In the case of a Stripped Certificate the payments on which consist
solely or primarily of a specified portion of the interest payments on the
Mortgage Loans ("Interest Weighted Stripped Certificate"), additional
uncertainty exists because of the enhanced potential for applicability of the
contingent principal provisions of the Contingent Regulations. The Contingent
Regulations do not, however, apply to debt instruments subject to Section
1272(a)(6).

         Possible Alternative Characterizations. The characterizations of the
Stripped Certificates described above are not the only possible interpretations
of the applicable Code provisions. Among other possibilities, the IRS could
contend that (i) in certain Series, each Stripped Certificate other than an
Interest Weighted Stripped Certificate is composed of an unstripped, undivided
ownership interest in Mortgage Loans and an installment obligation consisting
of stripped principal payments; (ii) the Stripped Certificates other than the
Interest Weighted Stripped Certificates are subject to the contingent payment
provisions of the Proposed Regulations; or (iii) each Interest Weighted
Stripped Certificate is composed of an unstripped undivided ownership interest
in Mortgage Loans and an installment obligation consisting of stripped interest
payments.

         Given the variety of alternatives for treatment of the Certificates
and the different federal income tax consequences that result from each
alternative, potential purchasers are urged to consult their own tax advisers
regarding the proper treatment of the Certificates for federal income tax
purposes.

         Character as Qualifying Mortgage Loans. In the case of Stripped
Certificates there is no specific legal authority existing regarding whether
the character of the Certificates, for federal income tax purposes, will be the
same as the Mortgage Loans. The IRS could take the position that the Mortgage
Loans' character is not carried over to the Certificates in such circumstances.
Pass-Through Certificates will be, and, although the matter is not free from
doubt, Stripped Certificates should be considered to represent "real estate
assets" within the meaning of Section 856(c)(4)(A) of the Code, and "loans
secured by an interest in real property" within the meaning of Section
7701(a)(19)(C)(v) of the Code (except that if the underlying Mortgage Loans are
not residential Mortgage Loans, the Certificates will not so qualify): interest
income attributable to the Certificates should be considered to represent
"interest on obligations secured by mortgages on real property or on interests
in real property" within the meaning of Section 856(c)(3)(B) of the Code.
Reserves or funds underlying the Certificates may cause a proportionate
reduction in the above-described qualification of Certificates.

         Sale of Certificates. As a general rule, if a Certificate is sold,
gain or loss will be recognized by the Holder thereof in an amount equal to the
difference between the amount realized on the sale and the Certificateholder's
adjusted tax basis in the Certificate. Such gain or loss will generally be
capital gain or loss if the Certificate is held as a capital asset. In the case
of Pass-Through Certificates, such tax basis will generally equal the Holder's
cost of the Certificate increased by any discount income with respect to the
loans represented by such Certificate previously included in income, and
decreased by the amount of any distributions of principal previously received
with respect to the Certificate. Such gain, to the extent not otherwise treated
as ordinary income, will be treated as ordinary income to the extent of any
accrued market discount not previously reported as income. Gain attributable to
a Certificate held as part of a conversion transaction or subject to an
election under Code Section 163(d)(4) may also be treated in whole or part as
ordinary income. See "--Sale or Exchange of REMIC Regular Interest
Certificates" above. In the case of Stripped Certificates, the tax basis will
generally equal the Certificateholder's cost 


                                      58
<PAGE>

for the Certificate, increased by any discount income with respect to the
Certificate previously included in income, and decreased by the amount of all
payments previously received with respect to such Certificate.

MISCELLANEOUS TAX ASPECTS

         Backup Withholding. A Certificateholder, other than a Residual
Interest Certificateholder, may, under certain circumstances, be subject to
"backup withholding" at the rate of 31% with respect to distributions or the
proceeds of a sale of certificates to or through brokers that represent
interest or original issue discount on the Certificates. This withholding
generally applies if the Holder of a Certificate (i) fails to furnish the
Trustee with its taxpayer identification number ("TIN"); (ii) furnishes the
Trustee an incorrect TIN; (iii) fails to report properly interest, dividends or
other "reportable payments" as defined in the Code; or (iv) under certain
circumstances, fails to provide the Trustee or such Holder's securities broker
with a certified statement, signed under penalty of perjury, that the TIN
provided is its correct TIN and that the Holder is not subject to backup
withholding. Backup withholding will not apply, however, with respect to
certain payments made to Certificateholders, including payments to certain
exempt recipients (such as exempt organizations) and to certain Nonresidents
(as defined below). Holders of the Certificates should consult their tax
advisers as to their qualification for exemption from backup withholding and
the procedure for obtaining the exemption.

         OID Regulations dealing with withholding tax on income paid to foreign
persons, backup withholding on income paid to U.S. persons and related matters
(the "New Withholding Regulations") were issued by the Treasury Department on
October 6, 1997. The New Withholding Regulations will generally be effective
for payments made after December 31, 1998, subject to certain transition rules.
Prospective Certificateholders are strongly urged to consult their own tax
advisors with respect to the New Withholding Regulations.

         The Trustee will report to the Certificateholders and to the Master
Servicer for each calendar year the amount of any "reportable payments" during
such year and the amount of tax withheld, if any, with respect to payments on
the Certificates.

TAX TREATMENT OF FOREIGN INVESTORS

         Under the Code, unless interest (including OID) paid on a Certificate
(other than a Residual Interest Certificate) is considered to be "effectively
connected" with a trade or business conducted in the United States by a
nonresident alien individual, foreign partnership or foreign corporation
("Nonresidents"), such interest will normally qualify as portfolio interest
(except where (i) the recipient is a holder, directly or by attribution, of 10%
or more of the capital or profits interest in the issuer or (ii) the recipient
is a controlled foreign corporation as to which the issuer is a related person)
and will be exempt from Federal income tax. Upon receipt of appropriate
ownership statements, the issuer normally will be relieved of obligations to
withhold tax from such interest payments. These provisions supersede the
generally applicable provisions of United States law that would otherwise
require the issuer to withhold at a 30% rate (unless reduced or eliminated by
an applicable tax treaty) on, among other things, interest and other fixed or
determinable, annual or periodical income paid to Nonresidents. Holders of
Pass-Through Certificates and Stripped Certificates, including Ratio
Certificates, however, may be subject to withholding to the extent that the
Mortgage Loans were originated on or before July 18, 1984. In addition,
prospective Certificateholders who are Nonresidents are strongly urged to
consult their own tax advisors with respect to the New Withholding Regulations.
See "-- Miscellaneous Tax Aspects -- Backup Withholding" above.



                                      59
<PAGE>

         Interest and OID of Certificateholders who are foreign persons are not
subject to withholding if they are effectively connected with a United States
business conducted by the Certificateholder. They will, however, generally be
subject to the regular United States income tax.

         Payments to Holders of Residual Interest Certificates who are foreign
persons will generally be treated as interest for purposes of the 30% (or lower
treaty rate) United States withholding tax. Holders should assume that such
income does not qualify for exemption from United States withholding tax as
"portfolio interest." It is clear that, to the extent that a payment represents
a portion of REMIC taxable income that constitutes excess inclusion income, a
Holder of a Residual Interest Certificate will not be entitled to an exemption
from or reduction of the 30% (or lower treaty rate) withholding tax. If the
payments are subject to United States withholding tax, they generally will be
taken into account for withholding tax purposes only when paid or distributed
(or when the Residual Interest Certificate is disposed of). The Treasury has
statutory authority, however, to promulgate regulations which would require
such amounts to be taken into account at an earlier time in order to prevent
the avoidance of tax. Such regulations could, for example, require withholding
prior to the distribution of cash in the case of Residual Interest Certificates
that do not have significant value. Under the Regulations, if a Residual
Interest Certificate has tax avoidance potential, a transfer of a Residual
Interest Certificate to a Nonresident will be disregarded for all Federal tax
purposes. A Residual Interest Certificate has tax avoidance potential unless,
at the time of the transfer, the transferor reasonably expects that the REMIC
will distribute to the transferee Residual Interest holder amounts that will
equal at least 30% of each excess inclusion, and that such amounts will be
distributed at or after the time at which the excess inclusion accrues and not
later than the close of the calendar year following the calendar year of
accrual. If a Nonresident transfers a Residual Interest Certificate to a United
States person, and if the transfer has the effect of allowing the transferor to
avoid tax on accrued excess inclusions, then the transfer is disregarded and
the transferor continues to be treated as the owner of the Residual Interest
Certificate for purposes of the withholding tax provisions of the Code. See
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES -- Excess Inclusions."

                            STATE TAX CONSIDERATIONS

         In addition to the Federal income tax consequences described in
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES," potential investors should consider
the state income tax consequences of the acquisition, ownership, and
disposition of the Certificates. State income tax law may differ substantially
from the corresponding federal law, and this discussion does not purport to
describe any aspect of the income tax laws of any state. Therefore, potential
investors should consult their own tax advisers with respect to the various
state tax consequences of an investment in the Certificates.

                              ERISA CONSIDERATIONS

         The Employee Retirement Income Security Act of 1974, as amended
("ERISA"), imposes certain requirements on employee benefit plans subject to
ERISA ("ERISA Plans") and prohibits certain transactions between ERISA Plans
and persons who are parties in interest (as defined in ERISA) ("parties in
interest") with respect to assets of such Plans. Section 4975 of the Code
prohibits a similar set of transactions between certain plans ("Code Plans,"
and together with ERISA Plans, "Plans") and persons who are disqualified
persons (as defined in the Code) (hereafter, also "parties in interest") with 
respect to Code 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 requirements of ERISA or Section 4975 of the 
Code, and assets of such plans may be invested in Certificates, subject to the 
provisions of other applicable federal and state law. Any such plan which is 
qualified under Section 401(a) of the Code and exempt from taxation under 
Section 501(a) of the Code is, however, subject to the prohibited transaction 
rules set forth in Section 503 of the Code.



                                      60
<PAGE>

         Investments by ERISA Plans are subject to ERISA's general fiduciary
requirements, including the requirement of investment prudence and
diversification and the requirement that investments be made in accordance with
the documents governing the ERISA Plan. Before investing in a Certificate, an
ERISA Plan fiduciary should consider, among other factors, whether to do so is
appropriate in view of the overall investment policy and liquidity needs of the
ERISA Plan. Such fiduciary should especially consider the sensitivity of the
investments to the rate of principal payments (including prepayments) on the
Mortgage Loans, as discussed in the Prospectus Supplement related to a Series.

         Based on the holding of the United States Supreme Court in John
Hancock Mutual Life Ins. Co. v. Harris Trust and Savings Bank, 510 U.S. 86
(1993), the assets of Plan may include assets held in the general account of an
insurance company. Before investing in a Certificate, an insurance company
should consider the effects of such holding on an investment of its general
accounts and the potential applicability of ERISA and Section 4975 of the Code.

PROHIBITED TRANSACTIONS

         Section 406 of ERISA and Section 4975 of the Code prohibit parties in
interest with respect to ERISA Plans and Code Plans from engaging in certain
transactions involving such Plans or "plan assets" of such Plans unless a
statutory or administrative exemption applies to the transaction. Section 4975
of the Code and Sections 502(i) and 502(l) of ERISA provide for the imposition
of certain excise taxes and civil penalties on certain persons that engage or
participate in such prohibited transactions. The Depositor, the Master
Servicer, any Special Servicer or the Trustee or certain affiliates thereof may
be considered or may become parties in interest with respect to an investing
Plan. If so, the acquisition or holding of Certificates by, on behalf of or
with "plan assets" of such Plan may be considered to give rise to a "prohibited
transaction" within the meaning of ERISA and/or the Section 4975 of Code unless
an administrative exemption described below or some other exemption is
available. Special caution should be exercised before "plan assets" of a Plan
are used to purchase a Certificate if, with respect to such assets, the
Depositor, the Master Servicer, any Special Servicer or the Trustee or an
affiliate thereof either (a) has investment discretion with respect to the
investment of such assets, or (b) has authority or responsibility to give, or
regularly gives investment advice with respect to such assets for a fee and
pursuant to an agreement or understanding that such advice will serve as a
primary basis for investment decisions with respect to such assets and that
such advice will be based on the particular investment needs of the Plan.

         Further, if the assets included in a Trust Fund were deemed to
constitute "plan assets," a Plan's investment in the Certificates may be deemed
to constitute a delegation, under ERISA, of the duty to manage plan assets by
the fiduciary deciding to invest in the Certificates, and certain transactions
involved in the operation of the Trust Fund may be deemed to constitute
prohibited transactions under ERISA and/or Section 4975 of the Code. Neither
ERISA nor Section 4975 of the Code defines the term "plan assets."

         The United States Department of Labor (the "Department") has issued 
regulations (the "Regulations") concerning whether or not a Plan's assets would
be deemed to include an interest in the underlying assets of an entity (such as
the Trust Fund), for purposes of the reporting and disclosure and general
fiduciary responsibility provisions of ERISA and the prohibited transaction
provisions of ERISA and Section 4975 of the Code, if the Plan acquires an
"equity interest" (such as a Certificate) in such an entity.

         Certain exceptions are provided in the Regulations whereby an
investing Plan's assets would be deemed merely to include its interest in the
Certificates instead of being deemed to include an interest in the assets of
the Trust Fund. However, it cannot be predicted in advance, nor can there be a
continuing assurance whether such exceptions may be met, because of the factual
nature of certain of the rules set forth in the Regulations. For example, one
of the exceptions in the Regulations states that the underlying 


                                      61
<PAGE>

assets of an entity will not be considered "plan assets" if less than 25% of
the value of each class of equity interests is held by "benefit plan
investors," which are defined as ERISA Plans, Code Plans, and employee benefit
plans not subject to ERISA (for example, governmental plans), but this
exemption is tested immediately after each acquisition of an equity interest in
the entity whether upon initial issuance or in the secondary market.

         Pursuant to the Regulations, if the assets of the Trust Fund were
deemed to be "plan assets" by reason of the investment of assets of a Plan in
any Certificates, the "plan assets" of such Plan would include an undivided
interest in the Mortgage Loans, the mortgages underlying the Mortgage Loans and
any other assets held in the Trust Fund. Therefore, because the Mortgage Loans
and other assets held in the Trust Fund may be deemed to be "plan assets" of
each Plan that purchases Certificates, in the absence of an exemption, the
purchase, sale or holding of Certificates of any Series or Class by or with
"plan assets" of a Plan may result in a prohibited transaction and the
imposition of civil penalties or excise taxes.

         Depending on the relevant facts and circumstances, certain prohibited
transaction exemptions may apply to the purchase, sale or holding of
Certificates of any Series or Class by a Plan, for example, Prohibited
Transaction Class Exemption ("PTCE") 96-23, which exempts certain transactions 
effected on behalf of a plan by an "in-house asset manager"; 95-60, which 
exempts certain transactions with insurance company general accounts; PTCE
91-38 (formerly PTCE 80-51), which exempts certain transactions between bank
collective investment funds and parties in interest; PTCE 90-1, which exempts
certain transactions between insurance company pooled separate accounts and
parties in interest; or PTCE 84-14, which exempts certain transactions effected
on behalf of a plan by a "qualified professional asset manager." Also, the
Department has issued administrative exemptions from application of certain
prohibited transaction restrictions of ERISA and Section 4975 of the Code to
most underwriters of mortgage-backed securities (each, an "Underwriter's
Exemption"). Such an Underwriter's Exemption can only apply to mortgage-backed
securities which, among other conditions, are sold in an offering with respect
to which such underwriter serves as the sole or a managing underwriter, or as a
selling or placement agent. If such an Underwriter's Exemption might be
applicable to a Series of Certificates, the related Prospectus Supplement will
refer to such possibility.

         ANY FIDUCIARY OR OTHER PLAN INVESTOR (WHICH COULD INCLUDE AN INSURANCE
COMPANY INVESTING GENERAL ACCOUNTS ASSETS) WHO PROPOSES TO INVEST "PLAN ASSETS"
OF A PLAN IN CERTIFICATES OF ANY SERIES OR CLASS SHOULD CONSULT WITH ITS
COUNSEL WITH RESPECT TO THE POTENTIAL CONSEQUENCES UNDER ERISA AND SECTION 4975
OF THE CODE OF ANY SUCH ACQUISITION AND OWNERSHIP OF SUCH CERTIFICATES.

UNRELATED BUSINESS TAXABLE INCOME -- RESIDUAL INTERESTS

         The purchase of a Certificate evidencing an interest in the Residual
Interest in a Series that is treated as a REMIC by any employee benefit or
other plan that is exempt from taxation under Code Section 501(a), including
most varieties of Plans, may give rise to "unrelated business taxable income"
as described in Code Sections 511-515 and 860E. Further, prior to the purchase
of an interest in a Residual Interest, a prospective transferee may be required
to provide an affidavit to a transferor that it is not, nor is it purchasing an
interest in a Residual Interest on behalf of, a "Disqualified Organization,"
which term as defined above includes certain tax-exempt entities not subject to
Code Section 511, such as certain governmental plans, as discussed above under
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES -- Taxation of Holders of Residual
Interest Certificates" and "--Restrictions on Ownership and Transfer of
Residual Interest Certificates."



                                      62
<PAGE>

         Due to the complexity of these rules and the penalties imposed upon
Persons involved in prohibited transactions, it is particularly important that
individuals responsible for investment decisions with respect to Plans consult
with their counsel regarding the consequences under ERISA and/or Section 4975
of the Code of their acquisitions and ownership of Certificates.

         The sale of Certificates to a Plan is in no respect a representation
by the Depositor or the applicable underwriter that such investment meets all
relevant legal requirements with respect to investments by Plans generally or
any particular Plan, or that such investment is appropriate for Plans generally
or any particular Plan.

                               LEGAL INVESTMENT

         The Prospectus Supplement for each Series will identify those Classes
of Certificates, if any, which constitute "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984 (the
"Enhancement Act").

         Such Classes will constitute "mortgage related securities" for so long
as they (i) are rated in one of the two highest rating categories by at least
one nationally recognized statistical rating organization and (ii) are part of
a Series evidencing interests in a trust fund consisting of loans originated by
certain types of originators as specified in the Enhancement Act (the "SMMEA
Certificates"). As "mortgage related securities," the SMMEA Certificates 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 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 the Enhancement Act, 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, in most cases by requiring the affected
investors to rely solely upon existing state law, and not the Enhancement Act.
Pursuant to Section 347 of the Riegle Community Development and Regulatory
Improvement Act of 1994, which amended the definition of "mortgage related
security" to include, in relevant part, certificates satisfying the rating and
qualified originator requirements for "mortgage related securities," but
evidencing interests in a trust fund consisting, in whole or in part, of first
liens on one or more parcels of real estate upon which are located one or more
commercial structures, states were authorized to enact legislation, on or
before September 23, 2001, specifically referring to Section 347 and
prohibiting or restricting the purchase, holding or investment by state-
regulated entities in such types of certificates. Accordingly, the investors
affected by such legislation when and if enacted, will be authorized to invest
in SMMEA Certificates only to the extent provided in such legislation.

         The Enhancement Act also amended the legal investment authority of
federally chartered depository institutions as follows: federal savings and
loan associations and federal savings banks may invest in, sell or otherwise
deal with, mortgage related securities without limitation as to the percentage
of their assets represented thereby, federal credit unions may invest in
mortgage related securities, and national banks may purchase mortgage related
securities for their own account without regard to the limitations generally
applicable to investment securities set forth in 12 U.S.C. Section 24
(Seventh), subject in each case to such regulations as the applicable federal
regulatory authority may prescribe. In this connection, effective December 31,
1996, the Office of the Comptroller of the Currency (the "OCC") has 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 any such bank's capital and
surplus (but subject to compliance 


                                      63
<PAGE>

with certain general standards concerning "safety and soundness" and retention
of credit information in 12 C.F.R. Section 1.5), certain "Type IV securities,"
defined in 12 C.F.R. Section 1.2(l) to include certain "commercial
mortgage-related securities" and "residential mortgage-related securities." As
so defined, "commercial mortgage-related security" and "residential
mortgage-related security" mean, in relevant part, "mortgage related security"
within the meaning of the Enhancement Act, provided that, in the case of a
"commercial mortgage-related security," it "represents ownership of a
promissory note or certificate of interest or participation that is directly
secured by a first lien on one or more parcels of real estate upon which one or
more commercial structures are located and that is fully secured by interests
in a pool of loans to numerous obligors." In the absence of any rule or
administrative interpretation by the OCC defining the term "numerous obligors,"
no representation is made as to whether any Class of Certificates will qualify
as "commercial mortgaged-related securities," and thus as "Type IV securities,"
for investment by national banks. Federal credit unions should review the NCUA
Letter to Credit Unions No. 96, as modified by Letter to Credit Unions No. 108,
which includes guidelines to assist federal credit unions in making investment
decisions for mortgage related securities. The NCUA has adopted rules, codified
as 12 C.F.R. Section 703.5(f) through (k), which prohibit federal credit unions
from investing in certain mortgage related securities (including securities
such as certain Series, Classes or subclasses of Certificates), except under
limited circumstances.

         All depository institutions considering an investment in the
Certificates should review the Supervisory Policy Statement on Securities
Activities dated January 28, 1992, as revised April 15, 1994 (the "Policy
Statement") of the Federal Financial Institutions Examination Council. The
Policy Statement, which has been adopted by the Board of Governors of the
Federal Reserve System, the FDIC, the Comptroller of the Currency and the
Office of Thrift Supervision and by the NCUA (with certain modifications)
prohibits depository institutions from investing in certain "high-risk"
mortgage securities (including securities such as certain Series, Classes or
subclasses of Certificates), except under limited circumstances, and sets forth
certain investment practices deemed to be unsuitable for regulated
institutions.

         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 SMMEA
Certificates, as SMMEA Certificates may be deemed unsuitable investments, or
may otherwise be restricted, under such rules, policies or guidelines (in
certain instances irrespective of the Enhancement Act).

         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 provisions which may restrict or prohibit
investments in securities which are issued in book entry form. Investors should
consult with their own legal advisers in determining whether, and to what
extent, SMMEA Certificates constitute legal investments for such investors.

         Other Classes of Certificates will not constitute "mortgage related
securities" under the Enhancement Act (the "Non-SMMEA Certificates"). The
appropriate characterization of the Non-SMMEA Certificates under various legal
investment restrictions, and thus the ability of investors subject to these
restrictions to purchase Non-SMMEA Certificates, may be subject to significant
interpretive uncertainties. All investors whose investment authority is subject
to legal restrictions should consult their own legal advisers to determine
whether, and to what extent, the Non-SMMEA Certificates will constitute legal
investments for them.



                                      64
<PAGE>

         Except as to the status of SMMEA Certificates identified in the
Prospectus Supplement for a Series as "mortgage related securities" under the
Enhancement Act, the Depositor will make no representation as to the proper
characterization of the Certificates for legal investment or financial
institution regulatory purposes, or as to the ability of particular investors
to purchase Certificates under applicable legal investment restrictions. The
uncertainties described above (and any unfavorable future determinations
concerning legal investment or financial institution regulatory characteristics
of the Certificates) may adversely affect the liquidity of the Certificates.



                              PLAN OF DISTRIBUTION

         Each Series of Certificates offered hereby and by means of the related
Prospectus Supplements may be sold directly by the Depositor or may be offered
through Credit Suisse First Boston Corporation, an affiliate of the Depositor,
or underwriting syndicates represented by Credit Suisse First Boston
Corporation (the "Underwriters"). The Prospectus Supplement with respect to
each such Series of Certificates will set forth the terms of the offering of
such Series of Certificates, including the name or names of the Underwriters,
the proceeds to the Depositor, and either the initial public offering price,
the discounts and commissions to the Underwriters and any discounts or
concessions allowed or reallowed to certain dealers, or the method by which the
price at which the Underwriters will sell such Certificates will be determined.

         Unless otherwise specified in the related Prospectus Supplement, the
Underwriters will be obligated to purchase all of the Certificates of a Series
described in the related Prospectus Supplement with respect to such Series if
any such Certificates are purchased. The Certificates may be acquired by the
Underwriters for their own account and may be resold from time to time in one
or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. If
specified in the applicable Prospectus Supplement, the Depositor will authorize
Underwriters or other persons acting as the Depositor's agents to solicit
offers by certain institutions to purchase the Certificates from the Depositor
pursuant to contracts providing for payment and delivery on a future date.
Institutions with which such contracts may be made include commercial and
savings banks, insurance companies, pension funds, investment companies,
educational and charitable institutions and others, but in all cases such
institutions must be approved by the Depositor. The obligation of any purchaser
under any such contract will be subject to the condition that the purchase of
the offered Certificates shall not at the time of delivery be prohibited under
the laws of the jurisdiction to which such purchaser is subject. The
Underwriters and such other agents will not have any responsibility in respect
of the validity or performance of such contracts.

         The Depositor may also sell the Certificates offered hereby by means
of the related Prospectus Supplements from time to time in negotiated
transactions or otherwise, at prices determined at the time of sale. The
Depositor may effect such transactions by selling Certificates to or through
dealers, and such dealers may receive compensation in the form of underwriting
discounts, concessions or commissions from the Depositor and any purchasers of
Certificates for whom they may act as agents. The place and time of delivery
for each Series of Certificates offered hereby and by means of the related
Prospectus Supplement will be set forth in the Prospectus Supplement with
respect to such Series.

                                 LEGAL MATTERS

         Certain legal matters relating to the Certificates offered hereby will
be passed upon for the Depositor and for the Underwriters by Brown & Wood LLP,
One World Trade Center, New York, New York 10048; Cadwalader, Wickersham &
Taft, 100 Maiden Lane, New York New York 10038; or Orrick,

ITEM 17.  UNDERTAKINGS.

         (a)      Undertaking pursuant to Rule 415.

         The Registrant hereby undertakes:

         (1)  To file, during any period in which offers or sales are being 
made, a post-effective amendment to this Registration Statement:

                  (i)  to include any prospectus required by Section 10(a)(3) of
         the Securities Act of 1933;

                  (ii) to reflect in the Prospectus any facts or events arising
         after the effective date of the Registration Statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the Registration Statement. Notwithstanding the foregoing, any
         increase or decrease in volume of 


                                      72
<PAGE>

         securities offered (if the total dollar value of securities offered
         would not exceed that which was registered) and any deviation from the
         low or high and of the estimated maximum offering range may be
         reflected in the form of prospectus filed with the Commission pursuant
         to Rule 424(b) if, in the aggregate, the changes in volume and price
         represent no more than 20 percent change in the maximum aggregate
         offering price set forth in the "Calculation of Registration Fee"
         table in the effective Registration Statement; and

                  (iii) to include any material information with respect to the
         plan of distribution not previously disclosed in the Registration
         Statement or any material change to such information in the
         Registration Statement; PROVIDED, HOWEVER, that paragraphs (a)(1)(i)
         and (a)(1)(ii) do not apply if the information required to be included
         in a post-effective amendment by those paragraphs is contained in
         periodic reports filed with or furnished to the Commission by the
         Registrant pursuant to Section 13 or Section 15(d) of the Securities
         Exchange Act of 1934 that are incorporated by reference in this
         Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.


         (b) Undertaking in respect of incorporation by reference.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

         (c) Undertaking in respect of indemnification.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

         (d) Undertaking in respect of equity offerings of nonreporting
registrants.



                                      73
<PAGE>

         The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements,
certificates in such denominations and registered in such names as required by
the underwriter to permit prompt delivery to each purchaser.

Registrant certifies that it has reasonable grounds to believe that it meets

Credit Suisse First Boston Mortgage
Securities Corp.
11 Madison Avenue
New York, New York 10010


Ladies and Gentlemen:

         We have acted as special counsel to Credit Suisse First Boston
Mortgage Securities Corp., a Delaware corporation (the "Registrant"), in
connection with the preparation and filing with the Securities and Exchange
Commission (the "Commission") of the Registration Statement on Form S-3 filed
by the Registrant with the Commission (the "Registration Statement"), in
connection with the registration under the Securities Act of 1933, as amended
(the "Act") of Commercial/Multifamily Pass-Through Certificates (the
"Certificates"). The Certificates are issuable in series (each, a "Series")
under separate Pooling and Servicing Agreements (the "Pooling and Servicing
Agreements") by and among the Registrant, the Master Servicer named therein and
the Trustee named therein. The Certificates of each Series are to be sold as
described in the Registration Statement and the prospectus and prospectus
supplement relating to such Series.

         We have examined such instruments, documents and records as we deemed
relevant and necessary as a basis for our opinion hereinafter expressed. In
such examination, we have assumed the following: (a) the authenticity of
original documents and the genuineness of all signatures; (b) the conformity to
the originals of all documents submitted to us as copies; and (c) the truth,
accuracy and completeness of the information, representations and warranties
contained in the records, documents, instruments and certificates we have
reviewed.

         Based on such examination, we are of the opinion that when the
issuance of each Series of Certificates has been duly authorized by appropriate
corporate action and the Certificates of such Series have been duly executed,
authenticated and delivered in accordance with the terms of the Pooling and
Servicing Agreement relating to such Series and sold in the manner described in
the Registration Statement and the prospectus and prospectus supplement
relating thereto, the Certificates of such Series will be legally issued, fully
paid, binding obligations of the trust created by each Pooling and Servicing
Agreement, and the holders of the Certificates of such Series will be entitled
to the benefits of the Pooling and Servicing Agreement, except as enforcement
thereof may be limited by applicable bankruptcy, insolvency, reorganization,
arrangement, fraudulent conveyance, moratorium, or other laws relating to or
affecting the rights of creditors generally and general principles of equity,
including concepts of materiality, reasonableness, good faith and fair dealing,
and the possible unavailability of specific performance or injunctive relief,
regardless of whether such enforceability is considered in a proceeding in
equity or at law.


<PAGE>

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever it appears in the
Registration Statement and the prospectus contained therein. In giving such
consent, we do not consider that we are "experts," within the meaning of the
term as used in the Act or the rules and regulations of the Commission issued
thereunder, with respect to any part of the Registration Statement, including
this opinion as an exhibit or otherwise.

                                         Very truly yours,

                                         /s/ Orrick, Herrington & Sutcliffe LLP

                                  May 4, 1998


Credit Suisse First Boston Mortgage
 Securities Corp.
11 Madison Avenue
New York, New York 10010


Ladies and Gentlemen:

         We have advised Credit Suisse First Boston Mortgage Securities Corp.
(the "Registrant") with respect to certain federal income tax aspects of the
issuance by the Registrant of its Commercial/Multifamily Mortgage Pass-Through
Certificates, issuable in series (the "Certificates"). Such advice conforms to
the description of selected federal income tax consequences to holders of the
Certificates that appears under the heading "Certain Federal Income Tax
Consequences" in the prospectus (the "Prospectus") forming a part of the
Registration Statement on Form S-3 (the "Registration Statement") as prepared
for filing by the Registrant with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act"), for
registration of the Certificates under the Act. Such description does not
purport to discuss all possible income tax ramifications of the proposed
issuance, but with respect to those tax consequences which are discussed, in
our opinion the description is accurate in all material respects.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever it appears in the
Registration Statement and the Prospectus. In giving such consent, we do not
consider that we are "experts," within the meaning of the term as used in the
Act or the rules and regulations of the Commission issued thereunder, with
respect to any part of the Registration Statement, including this opinion as an
exhibit or otherwise.

                                          Very truly yours,

                                          /s/ Orrick, Herrington & Sutcliffe LLP
                                          ORRICK, HERRINGTON & SUTCLIFFE LLP
