(1) The aggregate initial Class Certificate Balance of the Offered Certificates
    is subject to a permitted variance in the aggregate of plus or minus 5%.
(2) See "Class Definitions and Abbreviations" included in Appendix A hereto.
(3) See "Description of the Certificates -- Last Scheduled Distribution Date"
    herein.
 
   
    The Offered Certificates offered hereby will be purchased by NationsBanc
Capital Markets, Inc. and First Southwest Company (together, the "Underwriters")
from the Sponsor and will be offered by the Underwriters from time to time in
negotiated transactions or otherwise at varying prices to be determined at the
time of sale. Proceeds to the Sponsor from the sale of the Offered Certificates
are expected to be approximately 99.125% of the aggregate principal balance of
the Mortgage Loans as of the Cut-off Date, plus accrued interest, before
deducting issuance expenses payable by the Sponsor.
    
 
   
    The Offered Certificates are offered by the Underwriters, subject to prior
sale, when, as and if delivered to and accepted by the Underwriters and subject
to their right to reject orders in whole or in part. It is expected that
delivery of the Offered Certificates, other than the Class B-1 and Class B-2
Certificates, will be made in book-entry form only through the facilities of The
Depository Trust Company ("DTC") and that the Class B-1 and Class B-2
Certificates will be delivered at the offices of NationsBanc Capital Markets,
Inc. in Charlotte, North Carolina, in each case on or about May 30, 1996.

     Each of the Mortgage Loans was purchased by a Seller, and will be sold by
such Seller to Tryon Mortgage Funding, Inc. (the "Sponsor") for deposit to the
Pool prior to initial issuance of the Certificates.
 
     The rights of the holders of the Subordinate Certificates to receive
distributions with respect to the Mortgage Loans are subordinated to the rights
of the holders of Senior Certificates, and the rights of the holders of each
Class of Class B Certificates and the Class R Certificates to receive such
distributions will be further subordinated to such rights of the holders of the
Class or Classes of Class B Certificates with lower numerical Class designations
and all Classes of Class B Certificates, respectively, in each case only to the
limited extent described herein. See "Credit Enhancement" herein.
 
     THE YIELD TO INVESTORS ON EACH CLASS OF OFFERED CERTIFICATES WILL BE
SENSITIVE IN VARYING DEGREES TO, AMONG OTHER THINGS, THE RATE AND TIMING OF
PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) OF THE MORTGAGE LOANS. THE YIELD TO
MATURITY OF A CLASS OF OFFERED CERTIFICATES PURCHASED AT A DISCOUNT OR PREMIUM
WILL BE MORE SENSITIVE TO THE RATE AND TIMING OF PAYMENTS THEREON THAN A CLASS
PURCHASED AT PAR. HOLDERS OF CERTIFICATES SHOULD CONSIDER, IN THE CASE OF ANY
SUCH CERTIFICATES PURCHASED AT A DISCOUNT, THE RISK THAT A LOWER THAN
ANTICIPATED RATE OF PRINCIPAL PAYMENTS COULD RESULT IN AN ACTUAL YIELD THAT IS
LOWER THAN THE ANTICIPATED YIELD AND, IN THE CASE OF ANY OFFERED CERTIFICATES
PURCHASED AT A PREMIUM, THE RISK THAT A FASTER THAN ANTICIPATED RATE OF
PRINCIPAL PAYMENTS COULD RESULT IN AN ACTUAL YIELD THAT IS LOWER THAN THE
ANTICIPATED YIELD. THE YIELD TO INVESTORS IN THE OFFERED CERTIFICATES, AND
PARTICULARLY THE CLASS B-1 AND CLASS B-2 CERTIFICATES, ALSO WILL BE ADVERSELY
AFFECTED BY NET INTEREST SHORTFALLS AND BY REALIZED LOSSES. NO REPRESENTATION IS
MADE AS TO THE ANTICIPATED RATE OF PREPAYMENTS ON THE MORTGAGE LOANS, THE AMOUNT
AND TIMING OF NET INTEREST SHORTFALLS OR REALIZED LOSSES, OR THE RESULTING YIELD
TO MATURITY OF ANY CLASS OF CERTIFICATES.
 
     An election will be made to treat the Pool as a "real estate mortgage
investment conduit" (the "REMIC") for federal income tax purposes. As described
more fully herein and in the Prospectus, the Senior Certificates and the Class B
Certificates will constitute "regular interests" in the REMIC. See "Certain
Federal Income Tax Consequences" herein and in the Prospectus.
 
     There is currently no secondary market for the Offered Certificates and
there can be no assurance that such a market will develop or, if it does
develop, that it will continue.

Interest...................  On each Distribution Date, each Class of Offered
                               Certificates, to the extent Available Funds are
                               available for the distribution of interest on
                               such Class on such Distribution Date, as
                               described above under "Priority of
                               Distributions", generally will be entitled to
                               receive an amount allocable to interest equal to
                               the sum of (i) one month's interest at the
                               applicable Pass-Through Rate set forth on the

                               exceeded the amount actually distributed as
                               interest on such prior Distribution Dates and not
                               subsequently distributed ("Unpaid Interest
                               Shortfall"). The interest entitlement for each
                               Class of Offered Certificates described above
                               shall be reduced by the allocable share of Net

                               described herein under "Description of the
                               Certificates -- Distributions."
 
Principal (including
  prepayments).............  On each Distribution Date, to the extent Available
                               Funds are available therefor, principal
                               distributions in reduction of the Class
                               Certificate Balance of each Class of Offered
                               Certificates will be made in the order and
                               subject to the priorities set forth herein under
                               "Description of the
                               Certificates -- Distributions" in an aggregate
                               amount equal to such Class' allocable portion of
                               the Senior Principal Distribution Amount, the
                               Class A-4 Principal Distribution Amount or the
                               Subordinate Principal Distribution Amount, as
                               applicable.
 
                             In addition, on each Distribution Date up to and
                               including the Accretion Termination Date, the
                               Accretion Amount will be distributed as set forth
                               herein under "Description of the

                               Amount."
 
                             The Class B-3, Class B-4 and Class R Certificates
                               are not entitled to distributions of principal
                               until the Class Certificate Balance of each Class
                               of Offered Certificates has been paid in full.

                               be provided by the Subordinate Certificates as
                               described below. Credit enhancement for each
                               Class of Subordinate Certificates (other than the
                               Class R Certificates) will be provided by the
                               Class or Classes of Class B Certificates with
                               higher numerical Class designations, as described
                               below.

Subordination..............  The rights of holders of the Subordinate
                               Certificates to receive distributions with
                               respect to the Mortgage Loans in the Pool will be
                               subordinated to such rights of holders of the
                               Senior Certificates, and the rights of the
                               holders of each Class of Subordinate Certificates
                               (other than the Class B-1 Certificates) to
                               receive distributions will be further
                               subordinated to such rights of the holders of the
                               Class or Classes of Subordinate Certificates with
                               a higher priority of payment as described above
                               under "Priority of Distributions," in each case
                               only to the extent described herein.
 
                             The subordination of the Subordinate Certificates
                               to the Senior Certificates and the further
                               subordination within the Subordinate Certificates
                               are each intended to increase the likelihood of
                               timely receipt by the holders of Certificates
                               with a higher relative payment priority of the
                               maximum amount to which they are entitled on any
                               Distribution Date and to provide such holders
                               protection against losses resulting from defaults
                               on Mortgage Loans to the extent described herein.
                               The Subordinate Certificates also provide
                               protection to a lesser extent against Special
                               Hazard Losses, Bankruptcy Losses and Fraud
                               Losses. However, in certain circumstances, the
                               amount of available subordination (including the
                               limited subordination provided for certain types
                               of losses) may be exhausted and shortfalls in
                               distributions on the Certificates could result.
                               Holders of Senior Certificates will bear their
                               proportionate share of any losses realized on the
                               Mortgage Loans in excess of the available
                               subordination amount. See "Description of the
                               Certificates -- Priority of Distributions Among
                               Classes of Certificates," "-- Allocation of
                               Losses" and "Credit Enhancement -- Subordination

Master Servicing Fee and
  Other Expenses...........  As compensation for its services, the Master
                               Servicer will be entitled to retain, from amounts
                               received in respect of the Mortgage Loans which
                               are allocable to interest, an amount equal to the
                               Master Servicing Fee.
 
                             In addition to the Master Servicing Fee, there will
                               be deducted from amounts received in respect of
                               the Mortgage Loans which are allocable to
                               interest an amount sufficient to provide for the
                               payment of

<PAGE>   7
                               the Trustee's fee. As to each Mortgage Loan, the
                               sum of the Master Servicing Fee Rate and the rate
                               at which the Trustee's fee is determined is
                               referred to as the "Expense Rate." The "Net
                               Mortgage Rate" for each Mortgage Loan will equal
                               the Mortgage Rate thereon less the Expense Rate.
 
                             See "The Pooling and Servicing
                               Agreement -- Servicing Compensation and Payment
                               of Expenses" herein.
 
Advances...................  The Master Servicer is obligated to make cash
                               advances ("Advances") with respect to delinquent
                               payments of principal and interest on any
                               Mortgage Loan to the extent that such Advances
                               are determined by the Master Servicer to be
                               recoverable. The Trustee will be obligated to
                               make such Advance if the Master Servicer fails in
                               its obligation to do so, to the extent provided
                               in the Pooling Agreement. See "The Pooling and
                               Servicing Agreement -- Advances" herein.
 
                             With respect to any Mortgage Loan that is a Balloon
                               Loan, in the event of default in the scheduled
                               balloon principal payment (each, a "Balloon
                               Payment") due on the maturity of such Mortgage
                               Loan, the Master Servicer will not advance such
                               Balloon Payment. The Master Servicer will,
                               however, continue to advance each month, subject
                               to the Master Servicer's determination as to
                               recoverability, an amount equal to interest on
                               the principal balance of such Mortgage Loan
                               deemed to be due thereon and which is unpaid by
                               the Mortgagor after such default.
 
                             Any Advance made by the Master Servicer with
                               respect to a Mortgage Loan is reimbursable to it
                               as described herein under "The Pooling and
                               Servicing Agreement -- Advances." Under the
                               limited circumstances described herein, the
                               Master Servicer will be entitled to reimburse
                               itself from funds on deposit in the Collection
                               Account before distributions are made to holders
                               of Certificates.
 
Optional Termination.......  At its option, the Master Servicer may purchase
                               from the Pool all remaining Mortgage Loans in the
                               Pool and thereby effect early retirement of the
                               Certificates on any Distribution Date on which
                               the Pool Principal Balance is less than 10% of
                               the Cut-off Date Pool Principal Balance. See "The
                               Pooling and Servicing Agreement
                               Certificates -- Termination; Optional
                               Termination" herein.
 
                             IF THE MASTER SERVICER EXERCISES ITS RIGHT TO
                               REPURCHASE ALL OF THE MORTGAGE LOANS, THE
                               CERTIFICATES OUTSTANDING AT THE TIME OF SUCH
                               REPURCHASE WILL BE RETIRED EARLIER THAN WOULD
                               OTHERWISE BE THE CASE. See "Prepayment and Yield
                               Considerations" herein.
 
Optional Purchase of
  Mortgage Loans...........  Subject to certain conditions specified in the
                               Pooling Agreement, the Master Servicer has the
                               option, but is not obligated, (i) to purchase
                               from the Pool any Mortgage Loan 90 days or more
                               delinquent at the Purchase Price for such
                               Mortgage Loan or (ii) to sell any such Mortgage
                               Loan in a commercially reasonable manner if the
                               Master Servicer determines that such a sale would
                               produce a greater recovery on a present value
                               basis than would liquidation of the related
                               Mortgaged Property. See "The Pooling and
                               Servicing Agreement -- Optional Purchase of

Certain Federal Income Tax
  Consequences.............  An election will be made to treat the Pool as a
                               "real estate mortgage investment conduit"
                               ("REMIC") for federal income tax purposes. The
                               Regular Certificates will constitute "regular
                               interests" in the REMIC and will be treated as
                               debt instruments of the Pool for federal income
                               tax purposes with payment terms equivalent to the
                               terms of such Certificates. The Residual
                               Certificates will constitute the sole class of
                               "residual interest" in the REMIC.
 
                             Holders of the Offered Certificates will be
                               required to include in income interest on such
                               Certificates in accordance with the accrual
                               method of accounting. Certain Classes of the
                               Offered Certificates may, depending on their
                               respective issue prices, be treated as having
                               been issued with original issue discount for
                               federal income tax purposes. For further
                               information regarding the federal income tax
                               consequences of investing in the Certificates,

                               herein and in the Prospectus.
 
Legal Investment...........  The Offered Certificates will not constitute
                               "mortgage related securities" for purposes of the
                               Secondary Mortgage Market Enhancement Act of 1984
                               ("SMMEA"), because the substantial majority of
                               the Mortgage Loans were originated by individuals
                               and not by financial institutions or mortgagees
                               approved by the Secretary of Housing and Urban
                               Development and, in the case of the Class B-2
                               Certificates, such Certificates will not be rated
                               in one of the two highest rating categories by a
                               nationally recognized statistical rating
                               organization. Institutions whose investment
                               activities are subject to review by federal or
                               state regulatory authorities should consult with
                               their counsel or the applicable authorities to
                               determine whether an investment in the Offered
                               Certificates complies with applicable guidelines,
                               policy statements or restrictions. See "Legal
                               Investment Consideration" in the Prospectus.
 
                             Certain Classes of Certificates may be deemed
                               "high-risk mortgage securities" as defined in the
                               supervisory policy statement on securities
                               activities approved by the Federal Financial
                               Institutions Examination Council on December 3,
                               1991 and adopted by the Comptroller of the
                               Currency, the Federal Deposit Insurance

                               should carefully review with its legal advisors
                               whether the purchase or holding of an Offered
                               Certificate could give rise to a transaction
                               prohibited or not otherwise permissible under
                               ERISA or the Code. The Class B-1 and Class B-2
                               Certificates may not be transferred except upon
                               satisfaction of certain conditions. See "ERISA

                                  RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with the purchase of the Offered Certificates.
 
INDIVIDUAL ORIGINATORS
 
     Substantially all of the Mortgage Loans were originated by the individual
sellers of the related Mortgaged Property, who are generally inexperienced in
matters pertaining to mortgage banking, and subsequently acquired by a Seller.
Consequently, the Mortgage Loans were not originated pursuant to consistent
underwriting guidelines or similar mortgage loan documentation. Thus, it is
possible that this Prospectus Supplement does not contain information regarding
the Mortgage Loans which would have been available if the Mortgage Loans had
been originated by a financial institution. However, prior to any acquisition of
a Mortgage Loan by a Seller, such Mortgage Loan was subjected to the Seller's
acquisition underwriting criteria described herein under "The Mortgage
Pool -- Acquisition Underwriting Standards."
 
     Because no more than approximately 3% of the Mortgage Loans (by Cut-off
Date Pool Principal Balance) were originated by savings and loan associations,
saving banks, commercial banks, credit unions, insurance companies or similar
institutions which are supervised and examined by a Federal or State authority,
or by a mortgagee approved by the Secretary of Housing and Urban Development,
the Offered Certificates will not constitute "mortgage related securities" for
purposes of SMMEA.
 
     Federal laws requiring that flood insurance be in effect on mortgaged
properties identified by the Federal Emergency Management Agency ("FEMA") as
having special flood hazards only apply to mortgage loans originated by
federally regulated or insured lenders or originated for sale to a federal
instrumentality, such as the Federal National Mortgage Association ("FNMA").
Consequently, this requirement is not applicable to 97% of the Mortgage Loans
(by Cut-off Date Pool Principal Balance), and flood insurance has not been, or
will not be, so maintained whether or not the related Mortgaged Properties are
located in areas identified by FEMA as having special flood hazards.
 
REDUCED UNDERWRITING STANDARDS
 
     As described herein, the Sellers' acquisition underwriting standards are
generally less stringent than those of FNMA or the Federal Home Loan Mortgage
Corporation ("FHLMC") with respect to documentation, borrower's credit history,
calculation of debt ratios, employment and salary verification and certain other
respects. In addition, because the Sellers do not originate mortgage loans, but
rather acquire mortgage loans some time after origination, the Sellers are not
able to calculate certain of the ratios employed in underwriting a mortgage
loan, such as income to debt ratios, in a manner similar to FNMA and FHLMC
guidelines. As a result, the Mortgage Loans may experience higher rates of
delinquencies, defaults and foreclosures than mortgage loans underwritten in a
manner consistent with the FNMA and FHLMC guidelines. See "The Mortgage
Pool -- Acquisition Underwriting Standards" herein.
 
DELINQUENCY HISTORY
 
     As of the Cut-off Date, no Mortgage Loan was more than 59 days delinquent
and approximately 5.18% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) were between 30 days and 59 days delinquent.
 
     Certain of the Mortgage Loans have been delinquent one or more times since
origination. During the period commencing January 1, 1995 through April 15,
1996, approximately 31.15% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) have been 30 days delinquent at least once. During such period, 8.12%,
3.97%, 3.24%, 2.06% and 3.05% of the Mortgage Loans (by Cut-off Date Pool
Principal Balance) have been 30 days delinquent two times, three times, four
times, five times and more than five times, respectively. Generally the majority
of such 30 day delinquencies are corrected by the following Due Date for a
delinquent Mortgage Loan. During the period commencing January 1, 1995 through
April 15, 1996, approximately 7.74% of the Mortgage Loans (by Cut-off Date Pool
Principal Balance) have been 60 days delinquent at least once. During such
period, 2.08% and 0.76% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) have
 
                                       S-8
<PAGE>   11
 
been 60 days delinquent two times and more than two times, respectively. During
the period commencing January 1, 1995 through April 15, 1996, approximately
2.02% of the Mortgage Loans have been 90 days delinquent at least once. No
assurances can be given that the past delinquency performance of the Mortgage
Loans will be indicative of any delinquencies on the Mortgage Loans in the
future. Delinquency performance may be affected by, among other things, the lack
of late payment penalty provisions for some of the Mortgage Loans. In addition,
for those Mortgage Loans providing for late payment penalties, some do not
provide for penalties until the payment is 30 days or more past due.
 
YIELD AND PREPAYMENT CONSIDERATIONS
 
     The rate of principal payments on the Certificates, the amount of principal
and interest payments on the Certificates and the yield to maturity of the
Certificates will be directly related to the rate of payments of principal on
the Mortgage Loans. The rate of principal payments on the Mortgage Loans will in
turn be affected by the amortization schedules of the Mortgage Loans, the rate
of principal prepayments (including partial prepayments and those resulting from
refinancing) thereon by mortgagors, liquidations of defaulted Mortgage Loans,
optional purchases or sales by the Master Servicer of Mortgage Loans 90 days or
more delinquent, repurchases by the Sellers of Mortgage Loans as a result of
defective documentation or breaches of representations or warranties and
optional purchase by the Master Servicer of all of the Mortgage Loans in
connection with the termination of the Pool. Substantially all of the Mortgage
Loans may be prepaid in whole or in part at any time without penalty. Less than
1% of the Mortgage Loans (by Cut-off Date Pool Principal Balance) require the
payment of a prepayment penalty in connection with any prepayment in full of
such Mortgage Loans. In addition, certain of the Mortgage Loans contain
"due-on-sale" provisions and the Master Servicer may enforce such provisions,
unless (i) such enforcement is not permitted by applicable law or (ii) the
Master Servicer, in its discretion, waives its right to enforce such provision
and permits the purchaser of the Mortgaged Property to assume the Mortgage Loan.
To the extent permitted by applicable law, such assumption will not release the
original borrower from its obligation under any such Mortgage Loan. See "Certain
Legal Aspects of the Mortgage Loans -- Due-On-Sale Clauses" in the Prospectus.
The rate of prepayments may be slower than expected due to, among other reasons,
the inability of certain Mortgagors to obtain conventional refinancing. See "The
Mortgage Pool -- Acquisition Underwriting Standards" herein.
 
     The rate of payments (including prepayments) on mortgage loans is
influenced by a variety of economic, geographic, social and other factors. If
prevailing interest rates for similar mortgage loans fall below the Mortgage
Rates on the Mortgage Loans, the rate of prepayment would generally be expected
to increase. Conversely, if prevailing interest rates for similar mortgage loans
rise above the Mortgage Rates on the Mortgage Loans, the rate of prepayment
would generally be expected to decrease. An investor that purchases an Offered
Certificate at a discount should consider the risk that a slower than
anticipated rate of principal payments on the Mortgage Loans will result in an
actual yield that is lower than such investor's expected yield. An investor that
purchases an Offered Certificate at a premium should consider the risk that a
faster than anticipated rate of principal payments on the Mortgage Loans will
result in an actual yield that is lower than such investor's expected yield.
 
     The timing of changes in the rate of prepayments may significantly affect
an investor's actual yield to maturity, even if the average rate of principal
prepayments is consistent with an investor's expectations. In general, the
earlier a prepayment of principal of the Mortgage Loans the greater the effect
on an investor's yield to maturity. The effect on an investor's yield as a
result of principal payments occurring at a rate higher (or lower) than the rate
anticipated by the investor during the period immediately following the issuance
of the Offered Certificates will not be offset by a subsequent like reduction
(or increase) in the rate of principal prepayments.
 
     The absence of uniformity among the terms of the Mortgage Loans may cause
the risk of prepayment and default to vary more significantly among the Mortgage
Loans than among mortgage loans based on standardized documentation.
 
                                       S-9

SUBORDINATION OF CERTAIN CLASSES OF OFFERED CERTIFICATES
 
     The rights of the holders of the Subordinate Certificates to receive
distributions with respect to the Mortgage Loans will be subordinated to such
rights of the Senior Certificates and to the Subordinate Certificates with a
higher priority of payment as described herein under "Description of the
Certificates -- Priority of Distributions Among Classes of Certificates."
Delinquencies that are not advanced by or on behalf of the Master Servicer
(because the amounts, if advanced, would be nonrecoverable), will adversely
affect the yield on the Certificates. Because of the priority of distributions,
shortfalls resulting from delinquencies not so advanced will be borne first by
the Subordinate Certificates, in reverse order of their priority of payment as
described herein under "Description of the Certificates -- Priority of
Distributions Among Classes of Certificates" and then by the Senior
Certificates.
 
     The weighted average life of, and the yield to maturity on, the Subordinate
Certificates, in decreasing order of priority of payment, will be sensitive to
the rate and timing of Mortgagor defaults and the severity of ensuing losses on
the Mortgage Loans. If the actual rate and severity of losses on the Mortgage
Loans is higher than those assumed by a holder of such a Certificate, the actual
yield to maturity of such Certificate may be lower than the yield expected by
such holder based on such assumption. The timing of losses on the Mortgage Loans
will also affect an investor's actual yield to maturity, even if the rate of
defaults and severity of losses over the life of the Mortgage Loans are
consistent with such investor's expectations. In general, the earlier a loss
occurs the greater the effect on an investor's yield to maturity. Realized
Losses on the Mortgage Loans will reduce the Class Certificate Balance of the
applicable Class of Certificates to the extent of any losses allocated thereto
without the receipt of cash attributable to such reduction.
 
     See "Description of the Certificates -- Allocation of Losses" herein.
 
LIMITED OBLIGATIONS
 
     The Mortgage Loans will be the sole source of payments on the Certificates.
The Certificates do not represent an interest in or obligation of the Sponsor,
the Sellers, the Master Servicer, the Trustee or any of their affiliates, except
for limited obligations of each Seller for certain breaches of its
representations and warranties and defective documentation with respect to the
Mortgage Loans sold by it to the Sponsor. In addition, Metropolitan will have
limited obligations with respect to such breaches and defective documentation
relating to the Mortgage Loans sold by Western to the Sponsor if Western should
fail to perform its obligations with respect thereto and Summit will have
limited obligations with respect to such breaches and defective documentation
relating to the Mortgage Loans sold by Old Standard to the Sponsor if Old
Standard should fail to perform its obligations with respect thereto. Neither
the Certificates nor the Mortgage Loans will be guaranteed by or insured by any
governmental agency or instrumentality, the Sponsor, the Sellers, the Master
Servicer, the Trustee or any of their affiliates. Consequently, in the event
that payments on the Mortgage Loans are insufficient or otherwise unavailable to
make all payments required on the Certificates, there will be no recourse to the
Sponsor, the Sellers, the Master Servicer, the Trustee or any of their
respective affiliates.
 
LIQUIDITY
 
     The Underwriters intend to make a secondary market in the Offered
Certificates, but have no obligation to do so. There is currently no secondary
market in the Offered Certificates and there can be no assurance that such a
market will develop or, if it does develop, that it will provide
Certificateholders with liquidity of investment or that it will continue for the
life of the Certificates.
 
BALLOON LOANS
 
     Approximately 24.07% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) are Balloon Loans. As a result, a borrower generally will be required
to pay the entire remaining principal amount of the Mortgage Loan at its
maturity. The ability of a borrower to make such a payment may depend on the
ability of the borrower to obtain refinancing of the balance due on the Mortgage
Loan. An increase in interest rates over
 
                                      S-10
<PAGE>   13
 
the Mortgage Rate applicable at the time the Mortgage Loan was originated may
have an adverse effect on the borrower's ability to obtain refinancing or to pay
the required monthly payment.
 
     With respect to Balloon Loans, general credit risk may also be greater to
Certificateholders than to holders of instruments representing interests in
level payment fully amortizing first mortgage loans. Pursuant to the Pooling
Agreement, the Master Servicer is permitted to extend the date on which a
Balloon Payment is due on a Balloon Loan for a period of up to six months if the
Mortgagor defaults on the Balloon Payment or a default in respect of such
payment is imminent and such extension is reasonably likely to produce a greater
recovery with respect thereto than would otherwise be the case. See "The Pooling
and Servicing Agreement -- Modification of Mortgage Loans" herein.
 
GEOGRAPHIC CONCENTRATION
 
     Approximately 12.30% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) are secured by Mortgaged Properties located in the State of California.
Property values of residential real estate in California have declined in recent
years. If the California residential real estate market should continue to
experience an overall decline in property values after the dates of origination
of the Mortgage Loans, the rates of delinquency, foreclosure, bankruptcy and
loss on such Mortgage Loans may be expected to increase, and may increase
substantially, as compared to such rates in a stable or improving real estate
market.
 
BOOK-ENTRY SYSTEM
 
     Since transactions in the Book-Entry Certificates generally can be effected
only through DTC, Participants and Indirect Participants, the ability of a
Beneficial Owner to pledge Book-Entry Certificates to persons or entities that
do not participate in the DTC system, or to otherwise act with respect to such
Book-Entry Certificates, may be limited due to the lack of a physical
certificate for such Book-Entry Certificates. In addition, under a book-entry
format, Beneficial Owners may experience delays in their receipt of payments,
since distributions will be made by the Trustee, or a paying agent on behalf of
the Trustee, to CEDE & Co., as nominee for DTC. Also, issuance of Book-Entry
Certificates in book-entry form may reduce the liquidity thereof in any
secondary trading market that may develop therefor because investors may be
unwilling to purchase securities for which they cannot obtain delivery of
physical certificates. See "The Pooling and Servicing Agreement -- Book-Entry
Certificates" herein.
 
RATINGS OF CERTIFICATES
 
     It is a condition to the issuance of the Offered Certificates that they be
respectively rated as indicated under "Summary of Terms -- Certificate Ratings"
herein. A rating is based primarily on the credit underlying the Mortgage Loans,
the level of subordination, the amount of credit enhancement and the legal
structure of the transaction. The rating is not a recommendation to purchase,
hold or sell any of the Offered Certificates, as the case may be, inasmuch as
such rating does not comment as to the market price or suitability for a
particular investor. There can be no assurance as to whether any additional
rating agency will rate any or all of the Offered Certificates, or if it does,
that the rating that would be assigned by any such other rating agency would be
equivalent to the respective initial ratings. There is no assurance that the
ratings will remain for any given period of time or that ratings will not be
lowered or withdrawn by one or both of the Rating Agencies if, in their
judgment, circumstances so warrant.
 
                               THE MORTGAGE POOL
 
GENERAL
 
     Certain information with respect to the Mortgage Loans included in the
Mortgage Pool is set forth below. Prior to the Closing Date, Mortgage Loans may
be removed from the Mortgage Pool and other Mortgage Loans may be substituted
therefor. The Sponsor believes that the information set forth herein with
respect to the Mortgage Pool as presently constituted is representative of the
characteristics of the Mortgage Pool as it will be constituted at the Closing
Date, although the range of the Mortgage Rates and the maturities and
 
                                      S-11
<PAGE>   14
 
certain other characteristics of the Mortgage Loans in the Mortgage Pool may
vary. Unless otherwise indicated, information presented below expressed as a
percentage (other than rates of interest) are approximate percentages based on
the Cut-off Date Pool Principal Balance.
 
     The Sponsor will purchase the Mortgage Loans from each of the Sellers
pursuant to separate Mortgage Loan Purchase Agreements, each dated as of May 1,
1996 (each, a "Loan Purchase Agreement"), among such Seller and the Purchaser.
Pursuant to the Pooling Agreement, the Sponsor on the Closing Date will sell,
transfer, assign, set over and otherwise convey without recourse to the Trustee
in trust for the benefit of Certificateholders all right, title and interest of
the Sponsor in and to each Mortgage Loan and all right, title and interest in
and to all other assets included in the Pool, including all principal and
interest received by the Master Servicer on or with respect to the Mortgage
Loans after the Cut-off Date (to the extent not applied in computing the Cut-off
Date Pool Principal Balance), exclusive of interest accruing thereon on or prior
to the Cut-off Date.
 
     Under the Pooling Agreement, each Seller will make certain representations
and warranties to the Trustee concerning, among other things, the due execution
and enforceability of the Pooling Agreement by it and certain characteristics of
the related Mortgage Loans. Notwithstanding the information contained in the
Prospectus under "The Pooling and Servicing Agreement -- Representations and
Warranties," each Seller will represent and warrant that as to its Mortgage
Loans (i) as of the Cut-off Date, no Mortgage Loan was more than 59 days
delinquent, (ii) as of the Cut-off Date, other than normal wear and tear, each
Mortgaged Property has not declined materially in value due to damage or lack of
repair since acquisition or origination by the related Seller, and (iii) as of
the Cut-off Date, there are no delinquent tax or assessment liens against any
Mortgaged Property unless specifically set forth in a schedule attached to the
Pooling Agreement and the applicable Loan Purchase Agreement, as further
described below. Subject to the limitations described below under "The Pooling
and Servicing Agreement -- Assignment of the Mortgage Loans," the applicable
Seller and any other Seller responsible for a breach of another Seller's
representation or warranty will only be obligated to repurchase or substitute a
conforming mortgage loan for any Mortgage Loan sold to the Sponsor by that
Seller as to which there exists deficient documentation or an uncured material
breach of any such representation or warranty (each such Mortgage Loan, a
"Deleted Mortgage Loan"). The Sponsor will make no representations or warranties
with respect to the Mortgage Loans and will have no obligation to repurchase or
substitute for Mortgage Loans with deficient documentation or which are
otherwise defective. Each Seller is selling its Mortgage Loans without recourse
and, accordingly, will have no obligations with respect to the Certificates
other than pursuant to its representations, warranties, covenants and
substitution and repurchase obligations. See "The Pooling and Servicing
Agreement -- Assignment of the Mortgage Loans" herein.
 
     The Mortgage Loans were purchased by the Sellers in the ordinary course of
their respective businesses. Western, Summit and Old Standard acquired their
respective Mortgage Loans using the services of Metropolitan. Prior to its
acquisition, each Mortgage Loan was re-underwritten by Metropolitan in
accordance with its acquisition underwriting standards. See "-- Acquisition
Underwriting Standards" and "Risk Factors -- Reduced Underwriting Standards."
For its services for re-underwriting a Mortgage Loan, Metropolitan received a
fee from Western, Summit or Old Standard, whichever entity was the purchaser.
The Sellers also from time to time acquired certain of the Mortgage Loans in the
secondary market and originated certain of the Mortgage Loans to facilitate the
sale of their respective real estate acquired in foreclosure ("REO"). No more
than 5% of the Mortgage Loans are loans to facilitate the sale of REO and not
more than 3% of the Mortgage Loans were originated by financial institutions and
purchased in the secondary market by a Seller. The remainder of the Mortgage
Loans were originated by individuals and subsequently acquired by a Seller.
 
     Because substantially all of the Mortgage Notes, Mortgages, and Land Sale
Contracts were prepared by individual sellers of the Mortgaged Properties (or
their representatives), the form of the Mortgage Notes, Mortgages and Land Sale
Contracts vary significantly among the Mortgage Loans. For example, certain of
the Mortgage Loans contain "due on sale" provisions and less than 1% of the
Mortgage Loans contain prepayment penalties. Provisions regarding defaults for
reasons other than non-payment and grace periods for monthly payments also vary.
In addition, no more than 2% of the Mortgage Loans contain provisions which
require the mandatory partial release of the related Mortgaged Properties when
their respective principal balances have
 
                                      S-12
<PAGE>   15
 
been reduced to specified levels. Approximately 16.17% of the Mortgage Loans
contain provisions that require monthly payments due under the Mortgage Loan to
be held in escrow for the payment of taxes and insurance. The absence of
uniformity among the terms of the Mortgage Loans may cause the risk of
prepayment and default to vary more significantly among the Mortgage Loans than
among mortgage loans based on standardized documentation. See "Risk
Factors -- Individual Originators" and " -- Reduced Underwriting Standards"
herein.
 
     The Mortgage Pool will consist of approximately 3,309 fixed rate Mortgage
Loans with an aggregate Scheduled Principal Balance as of the Cut-off Date
expected to be approximately $122,865,169.49 (the "Cut-off Date Pool Principal
Balance"). As of the Cutoff Date, the Scheduled Principal Balances of the
Mortgage Loans ranged from $3,252.85 to $465,186.73 (each individually, a
"Cut-off Date Scheduled Principal Balance").
 
     Each of the Mortgage Loans is evidenced by a promissory note or, in the
case of a Land Sale Contract (as discussed in the following paragraph), a
promise to pay which is an integral part of the Land Sale Contract (each, a
"Mortgage Note").
 
     A sale of real estate pursuant to a Land Sale Contract differs in certain
respects from a sale in which title to the real estate is transferred to the
buyer and the buyer gives the seller a promissory note secured by real estate.
Generally, a "Land Sale Contract" is evidenced by a purchase agreement for the
sale of real estate that obligates the purchaser to make periodic payments to
the seller. The seller remains the record owner of and the holder of legal title
to the real estate until all required payments have been made by the purchaser.
Upon payment in full of the amounts due under the Land Sale Contract, the
purchaser receives a deed showing the purchaser as the owner of the real estate.
Procedures for clearing title to the real estate in the event of a default by
the purchaser differ from state to state and may be different from the
procedures required to foreclose under a deed of trust or mortgage. See "Certain
Legal Aspects of the Mortgage Loans -- Land Sale Contracts" in the Prospectus.
Assignment of a Land Sale Contract includes a transfer of title by deed to the
assignee. Approximately 23.03% of the Mortgage Loans are evidenced by Land Sale
Contracts.
 
     Each Mortgage Loan either is secured by a first lien mortgage, deed of
trust or other similar security instrument (each, a "Mortgage") on, or is a Land
Sale Contract for the sale of, one- to four-family residential real estate,
including individual condominium units and manufactured housing (each, a
"Mortgaged Property"). The Mortgages relating to each manufactured home secures,
and the Land Sale Contracts for each manufactured home relates to the sale of,
the manufactured home and the real property on which such manufactured home is
situated.
 
     Approximately 4.86% of the Mortgage Loans are secured by manufactured
housing. Under the Pooling Agreement, all manufactured homes are required to
comply with the requirements of certain federal statutes which require the
manufactured homes to have a minimum of 400 square feet of living space and a
minimum width of 102 inches and to be of a kind customarily used at a fixed
location. Such statutes also require the manufactured homes to be transportable
in one or more sections, built on a permanent chassis and designed to be used as
dwellings, with or without permanent foundations, when connected to the required
utilities. The manufactured homes are also required to include the plumbing,
heating, air conditioning and electrical systems therein.
 
     Approximately 5.29% of the Mortgage Loans are secured by condominium units.
 
     No more than 1% of the Mortgage Loans consist of dwellings situated on
leasehold estates. Under the Pooling Agreement, each Seller will represent as to
the Mortgage Loans sold by it that are situated on leasehold estates that such
leasehold estates contain certain standard provisions necessary to protect the
lien of the Trustee, including adequate time for the Trustee (as leasehold
mortgagee) to cure any default by the borrower, to assume the existing lease, or
enter into a new lease on similar terms with respect to the Mortgaged Property.
 
     Except for the Balloon Loans, all of the Mortgage Loans provide for
substantially equal monthly installments of principal and interest resulting in
the full amortization of the principal amount thereof over the term of the
respective Mortgage Loan. The Mortgage Loans provide for monthly payments due on
various
 
                                      S-13
<PAGE>   16
days each month (each, a "Due Date"). Scheduled monthly payments made by the
Mortgagors on the Mortgage Loans ("Scheduled Payments") either earlier or later
than the related Due Date will not affect the amortization schedule or the
relative application of such payments to principal and interest. A "Mortgagor"
is the obligor under either a Mortgage Note or a Land Sale Contract.
 
     Because certain of the Mortgage Loans do not have a maturity date stated on
the related Mortgage Note, the Master Servicer has calculated a maturity date
for each Mortgage Loan (each, a "Calculated Maturity Date"). With respect to any
Mortgage Loan, other than a Balloon Loan, the Calculated Maturity Date is the
date upon which the Scheduled Payment for such Mortgage Loan fully amortizes the
Scheduled Principal Balance of such Mortgage Loan as of April 1, 1996 and with
respect to any Balloon Loan, the date specified as the maturity date therefor on
the related Mortgage Note. The latest Calculated Maturity Date of any Mortgage
Loan is January 12, 2054. The earliest Calculated Maturity Date for any Mortgage
Loan is July 1, 1996.
 
     Approximately 24.07% of the Mortgage Loans are Balloon Loans. A "Balloon
Loan" either (i) provides for a Scheduled Payment based on an amortization term
ending at least three months beyond the Calculated Maturity Date for such
Mortgage Loan and a Balloon Payment due on such Calculated Maturity Date equal
to or exceeding $2,500 (each calculated based on April 1, 1996 Scheduled
Principal Balances) or (ii) provides for interest only Scheduled Payments on
each Due Date prior to the Calculated Maturity Date for such Mortgage Loan and a
Balloon Payment due on such Calculated Maturity Date equal to the entire
principal balance of such Mortgage Loan. The latest Calculated Maturity Date for
any Balloon Loan is September 15, 2033, and the earliest Calculated Maturity
Date for any Balloon Loan is July 1, 1996. The Balloon Payments for the Balloon
Loans range from $2,590.83 to $331,120.60, and the average Balloon Payment is
$43,548.17.
 
     Because no Mortgage Loan has been outstanding for less than six months,
modifications to the original terms of certain of the Mortgage Loans may have
been made in the normal course of servicing the Mortgage Loans. Approximately
16.26% of the Mortgage Loans have had modifications to their original terms. See
"Servicing of the Mortgage Loans -- Mortgage Loan Servicing -- Accelerations and
Modifications Department" and "Risk Factors -- Reduced Underwriting Standards"
herein. Such modifications may include the conversion of adjustable-rate loans
to fixed-rate loans, the extension of the term on Balloon Loans or the
elimination of the Balloon Payment through conversion of such Mortgage Loan to a
fully amortizing Mortgage Loan or the modification of a Mortgage to include the
manufactured home situated on the related real property. Under the Pooling
Agreement, each Seller will represent as to the Mortgage Loans sold by it that
any such modifications are set forth in writing and contained in the related
Mortgage Files transferred to the Trustee. For a description of the type of
modifications that are permitted to be made to the Mortgage Loans by the Master
Servicer pursuant to the Pooling Agreement, see "The Pooling and Servicing
Agreement -- Modification of Mortgage Loans."
 
     The "Loan-to-Value Ratio" of the Mortgage Loan at any given time is a
fraction expressed as a percentage, the numerator of which is the Scheduled
Principal Balance of such Mortgage Loan as of such date of determination and the
denominator of which is the Appraised Value. The "Appraised Value" with respect
to a Mortgage Loan, is the value of the applicable Mortgaged Property, based
upon the most recent valuation by an appraiser, which generally is an exterior
appraisal, which was obtained by the applicable Seller in connection with the
acquisition, modification or servicing of such Mortgage Loan. For a description
of the type of appraisal obtained in connection with the acquisition,
modification or servicing of a Mortgage Loan, see "-- Acquisition Underwriting 
Standards." No assurance can be given that the value of any Mortgaged Property
has remained or will remain at the level that existed on the appraisal date. If
residential real estate values generally or in a particular geographic area
decline, the Loan-to-Value Ratios might not be a reliable indicator of the
losses that could occur with respect to such Mortgage Loans. See "Risk Factors
- -- Geographic Concentration" herein. No Mortgage Loan will have a Loan-to-Value
Ratio as of the Cut-off Date of more than 123.79%. The weighted average of the
Loan-to-Value Ratios as of the Cut-off Date was approximately 67.40%. None of
the Mortgage Loans is insured by any primary mortgage guarantee insurance
policy.
 
                                      S-14
<PAGE>   17
     No Mortgage Loan was more than 59 days delinquent as of the Cut-off Date.
As of the Cut-off Date approximately 5.18% of the Mortgage Loans were between
30-59 days delinquent. See "Risk Factors -- Delinquency History" herein.
 
     As of the Cut-off Date, (i) no more than 11.68% of the Mortgage Loans had
taxes or other governmental assessments which were delinquent (such amounts
ranging from $0.57 to $6,965.13) and (ii) no more than 25.52% of the Mortgage
Loans had hazard insurance in effect that was force placed by the Master
Servicer. Any delinquent taxes with respect to a Mortgage Loan may be reflected
in a negative balance in the escrow account for which the Master Servicer is
reimbursed monthly by the borrower. Alternatively, the delinquent taxes may have
been capitalized as principal due on the Mortgage Loan, which in some cases may
have resulted in the creation of a Balloon Loan. Following the Closing Date, the
Master Servicer will not be permitted under the Pooling Agreement to capitalize
as principal due on a Mortgage Loan any taxes or hazard insurance premiums that
become delinquent.
 
     Approximately 97% of the Mortgage Loans are not required by federal law to
have flood insurance on the related Mortgaged Property whether or not such
property is in an area identified by FEMA as having special flood hazards.
Consequently, such flood insurance has not been nor will be maintained with
respect to the related Mortgaged Properties. See "Risk Factors -- Individual
Originators". For a description of the hazard insurance required to be
maintained on the Mortgaged Properties by the Master Servicer under the Pooling
Agreement, see "The Pooling and Servicing Agreement -- Hazard Insurance."
 
     To the best of each Seller's knowledge, based upon its respective review of
the related Mortgage Files, approximately 99% of the Mortgage Loans were
originated for the purpose of purchasing the related Mortgaged Property.
 
     None of the Mortgage Loans will be subject to a buy-down agreement. No
Mortgage Loan provides for deferred interest or negative amortization. The title
insurance policies for the Mortgage Loans assigned to the Trustee do not contain
environmental endorsements. For a description of the amount of title insurance
obtained in connection with the acquisition of a Mortgage Loan by a Seller, see
"-- Acquisition Underwriting Standards."
 
     The following tables set forth certain statistical information regarding
the Mortgage Loans as of the Cut-off Date. The balances and percentages may not
be exact due to rounding.

ACQUISITION UNDERWRITING STANDARDS
 
     In general, approximately 80% of all real estate secured loans purchased by
the Sellers, including residential, commercial and unimproved land loans, are
seller financed loans and are acquired through independent brokers located
throughout the country. These brokers typically deal directly with private
individuals or organizations who own and wish to sell a loan. Approximately 5%
of all loans purchased result from direct inquiries by owners of loans. There
are many reasons a borrower may choose to obtain seller financing in the
purchase of a property (including attractive loan terms from the seller, the
location of the property in a rural area where financing opportunities are not
readily available or have unattractive terms or the borrower may be unable to
obtain conventional financing). Loans have also been acquired from banks,
savings and loan organizations, mortgage companies, the Resolution Trust
Corporation and the Federal Deposit Insurance Corporation.
 
     Each mortgage loan secured by a first lien on a one- to four-family
residential property must satisfy Metropolitan's underwriting guidelines before
the mortgage loan can be acquired by a Seller. See "Risk Factors -- Reduced
Underwriting Standards" herein. Metropolitan's Underwriting Department reviews
the demography reports, credit reports on the mortgagor, the seasoning of the
investments, and the appraisal in making its evaluation of a proposed
investment. The underwriting guidelines are intended to evaluate the adequacy of
each mortgaged property as collateral for, and, to a lesser extent, the ability
of a borrower to repay, the related mortgage loan.
 
     The members of Metropolitan's Underwriting Department, as a committee,
review all proposed acquisitions of loans secured by real estate if, based on
Metropolitan's internal classification procedures for the loan, the dollar
amount of the proposed investment is above the credit limit for an individual
underwriter's approval authority. In many instances, an underwriter will present
a mortgage loan to the Underwriting Committee for its review even though the
dollar amount of the proposed investment is below that underwriter's credit
limit if the underwriter believes that the loan possesses characteristics which
the Underwriting Committee as a whole should discuss. The maximum investment an
individual underwriter may approve cannot exceed $100,000. All mortgage loans
that involve initial investments greater than $250,000 also are evaluated and
approved by a risk evaluation committee, Metropolitan's Legal Department and
Metropolitan's President. In addition, mortgage loans that involve investments
in excess of $500,000 are approved by Metropolitan's Board of Directors.
 
     The underwriting guidelines include a requirement that the ratio of the
Seller's proposed purchase price for a mortgage loan compared to the appraised
value of the related mortgaged property may not exceed 80% on mortgage loans
secured by single family residences. Loan-to-value ratios based on the
outstanding balance of a mortgage loan and the value of related mortgaged
property at the date of origination are not computed and may be higher than the
ratios computed by Metropolitan at the time of acquisition by a Seller.
 
     A current appraisal of the market value of each mortgaged property
generally is obtained within 60 days prior to the purchase of a mortgage loan.
However, in certain instances, Metropolitan may utilize a previous appraisal if
it was completed within six months prior to the purchase by a Seller. In such
cases, the appraisal reports are reviewed and certified by Metropolitan's
internal staff appraisers.
 
     The appraisals are made by licensed independent appraisers or an appraiser
on the staff of Metropolitan. Payments to appraisers are not contingent upon
either final approval of the acquisition of the mortgage loan or the appraised
value of the mortgaged property. Each appraisal by an independent appraiser is
reviewed by a licensed Metropolitan staff appraiser.
 
     Generally, the appraisals are based on drive-by exterior viewings of the
mortgaged property and comparative sales analysis. Appraisals involving
potential loan modifications and foreclosed property usually are conducted in
the same manner. However, in a limited number of cases, full appraisals are
obtained in which both the interior and exterior of the mortgaged property are
inspected. A full appraisal is always obtained after a property is obtained
through foreclosure or otherwise. Regardless of the type of appraisal requested,
each appraisal report must contain photographs, a site location map, plat map,
photographs of sold
 
                                      S-21
<PAGE>   24
 
properties comparable to the mortgaged property, and a map indicating the
proximity of the comparable properties to the mortgaged property.
 
     Metropolitan's Demography Department provides a variety of information to
the Underwriting Department, including various reports regarding the
characteristics of the area in which the property that secures a proposed
mortgage loan acquisition is located. In preparing its reports, the Demography
Department utilizes computerized databases and identifies local trends in
property values, personal income, population and other social and economic
factors.
 
     Other underwriting procedures generally include (i) obtaining and
evaluating credit reports with respect to a borrower, (ii) in certain cases,
obtaining and evaluating property inspection reports describing the mortgaged
property and the surrounding neighborhood, (iii) evaluating potential
environmental risks, (iv) verifying payment histories of the mortgage loan to be
acquired (when such payment histories are available) and the current payment
status of a borrower, and (v) evaluating a borrower's equity in the mortgaged
property.
 
     With respect to evaluating the creditworthiness of the mortgagor for a
particular mortgage loan, the Underwriting Committee obtains and reviews a
credit report for such mortgagor and the payment history for such mortgage loan,
if available. Because a mortgage loan is acquired after origination,
Metropolitan is unable to obtain and consider information that is typically
obtained in the origination of a mortgage loan, such as income, current
employment and total assets of the mortgagor. See "Risk Factors -- Reduced
Underwriting Standards."
 
     If a loan is approved for purchase by the Underwriting Department,
Metropolitan requires certain procedures to be followed to complete the
acquisition. In addition to requiring certain legal documentation regarding the
mortgage loan, Metropolitan may require other information, including the closing
statement used in the origination of the mortgage loan and payment records. With
respect to title insurance, if the purchase involves an interest in a land sale
contract, a title report from a title insurance company is ordered by
Metropolitan and a title policy is obtained in the amount of the outstanding
balance. If the purchase involves a mortgage loan, other than a land sale
contract, a copy of the lender's title insurance policy that was issued at the
origination of the loan is requested. If that policy shows clear title and the
endorsements on the related note establish a clear chain of title to the seller
of the loan, Metropolitan will not require an endorsement of such title policy.
Upon the occurrence of an event covered by the title policy, Metropolitan is
entitled to received reimbursement from the related seller of the mortgage loan
as a result of a violation of certain representations made by such seller at the
time of acquisition by a Seller. In those instances where a title policy is not
available or the chain of title is not clear, Metropolitan obtains a title
policy generally in the amount of the outstanding principal balance of the loan.
In some instances for certain loans acquired prior to 1991 and for certain loans
secured by properties in certain counties and states, Metropolitan requires a
lesser amount of title insurance, generally in the amount of the Seller's
investment in the mortgage loan, but in no case less than a minimum amount of
$10,000.
 
                           DESCRIPTION OF THE SELLERS
 
     Metropolitan, a Washington corporation, commenced business in January 1953.
It is primarily engaged in the business of investing in seller financed real
estate loans and other receivables. Metropolitan has fifteen branch offices
located in twelve states. At September 30, 1995, Metropolitan had total assets
of approximately $1.078 billion. Metropolitan's largest subsidiary, Western, a
life insurance and annuity company, was incorporated in the State of Washington
in 1963 and had total assets of approximately $922.1 million at September 30,
1995.
 
     Summit was incorporated in the State of Idaho in 1990 and is a subsidiary
of its holding company, National Summit Corp., a Delaware corporation. At
September 30, 1995, Summit had total assets of approximately $96.4 million.
Summit Group Holding Company, a subsidiary of Summit, acquired its wholly owned
life insurance company subsidiary, Old Standard, from Metropolitan in 1995. Old
Standard was incorporated in Idaho in 1988 and at September 30, 1995 had total
assets of approximately $55.6 million.

                          SERVICING OF MORTGAGE LOANS
 
GENERAL
 
     The Master Servicer will service the Mortgage Loans in accordance with the
terms set forth in the Pooling Agreement. The Master Servicer may perform any of
its obligations under the Pooling Agreement through one or more subservicers.
Notwithstanding any such subservicing arrangement, the Master Servicer will
remain liable for its servicing duties and obligations under the Pooling
Agreement as if the Master Servicer alone were servicing the Mortgage Loans. See
"The Pooling and Servicing Agreement" herein.
 
     Spokane Mortgage Co. ("SMC" or the "Master Servicer"), a Washington
corporation, is a subsidiary of Metropolitan. SMC has been in the business of
servicing mortgage loans and other assets since its incorporation in 1960 for
Metropolitan and the other Sellers. At December 31, 1995, SMC was servicing
approximately 17,460 mortgage loans secured by properties located in all 50
states representing an aggregate outstanding principal balance of approximately
$661 million and was servicing approximately 1,389 other receivables
representing an aggregate principal balance of approximately $154 million.
 
     The principal executive offices of SMC are located at 917 W. Sprague
Avenue, Spokane, Washington 99204. SMC also does business under the trade name
"MetWest Services."
 
MORTGAGE LOAN SERVICING
 
     The following is a discussion of SMC's servicing practices generally
applicable to the servicing of the Mortgage Loans by SMC, as Master Servicer.
References to mortgage loans in the following discussion include land sale
contracts in all cases.
 
     When a mortgage loan is acquired by a Seller, SMC's computer system
automatically generates a welcome letter and two loan coupons. A payment coupon
book for twelve monthly payments is printed annually by an independent vendor
and mailed to the borrower. In the course of servicing the mortgage loans, SMC
has access to a file containing copies of the original mortgage note or land
sale contract, security document, assignment of security interest and all other
information and reports that were accumulated as part of the acquisition,
underwriting and closing process for the mortgage loan.
 
  Loan Servicing and Cashiering Department
 
     SMC's Cashiering Department is responsible for receiving and applying
payments on the mortgage loans serviced by SMC. SMC's computer payment
processing system allocates payments first to accrued interest, then to
scheduled principal, and finally to any fees or miscellaneous charges due. The
system is programmed to accept and process the regular scheduled monthly payment
first with any overages posted to unallocated status. Curtailments are allocated
to principal if so indicated by the borrower, otherwise they will be posted to
unallocated status.
 
     SMC's Loan Servicing Department includes three separate groups: Receivable
Accounting, Customer Service, and Escrow Servicing. The Receivable Accounting
group is responsible for maintaining accurate receivable account histories and
records, conducting periodic audits, and making any on-line account adjustments.
They are also responsible for investor reporting and remittances.
 
     Customer Service is responsible for processing and preparing various
documents related to full payment of the mortgage loans, such as reconveyance
and "paid-in-full" stamped promissory notes. It is also responsible for
responding to borrower inquiries, except those involving delinquency or
litigation. If a borrower inquiry involves a dispute, the borrower is encouraged
to write a letter to which SMC will respond in writing. Borrower inquiries
regarding loan assumptions are referred to the Accelerations and Modifications
Department (described below) while those calls regarding delinquencies are
referred to the Default Control Department.
 
                                      S-23
<PAGE>   26
 
     Escrow Servicing is primarily responsible for paying property taxes and
insurance out of escrowed funds for those mortgage loans with escrow accounts,
processing insurance claims, and otherwise monitoring the payment of property
taxes and insurance on all mortgage loans.
 
     SMC utilizes a hazard insurance monitoring program provided by Safeco
Select Insurance Services ("SSIS"), an affiliate of Safeco National Insurance
Company ("Safeco"). Hazard insurance is required in an amount at least equal to
the outstanding principal balance of the mortgage loan. If the hazard insurance
lapses, SSIS sends a letter to the borrower informing the borrower that the
mortgage loan requires hazard insurance and providing the required minimum
amount, cost and a contact phone number. If no response from the borrower is
received within 30 days, SSIS sends an additional letter to the borrower. If
proof of hazard insurance is not provided within 60 days, hazard insurance will
be forced placed with Safeco. The owner of the mortgage loan is covered against
loss during that 60 day period by insurance underwritten by Safeco. Any hazard
insurance that is force placed will be placed for a twelve-month term with
coverage in the greater of the amount of the outstanding principal balance or
the last known amount for which the borrower had insured the related mortgaged
property, subject to any limitations imposed by applicable law.
 
     The Escrow Servicing group is also responsible for monitoring hazard
insurance claims. If any insurance proceeds are less than $5,000 and the
mortgage loan is not in default, the proceeds generally will be endorsed to the
borrower. If insurance proceeds are greater than $5,000, SMC orders an
inspection of the mortgaged property and obtains repair estimates and start-up
costs. SMC prefers to disburse funds on an as-completed basis after funding the
initial start-up costs.
 
     Escrow Servicing also utilizes a property tax service provided by First
American Tax Company to verify the payment of real estate taxes on a monthly
basis. If any property taxes are found to be delinquent, generally the borrower
is notified both verbally and in writing. If the amount of the delinquent tax is
less than $1,000 and overdue for no more than one year, Escrow Servicing will
take no action other than notification. If the amount of the delinquent tax is
greater than $1,000 and remains outstanding for longer than 45 days, or the
property taxes are two or more years delinquent, the mortgage loan will be
treated as delinquent and referred to the Accelerations and Modifications
Department.
 
  Default Control Department and Pre-foreclosure Committee
 
     SMC's Default Control Department is responsible for attempting to collect
the amount of any delinquency on a mortgage loan. Generally, if a payment
becomes five days delinquent, a late notice will automatically be sent to the
borrower notifying the borrower of the delinquency and the late charge. When 17
days delinquent, the mortgage loan will be assigned to a collector in the
Default Control Department who will attempt to make verbal contact with the
borrower no later than the 20th day following delinquency. Thereafter, contact
will be made by the collector as frequently as deemed necessary and permitted by
law until the delinquency is resolved. Generally, if a mortgage loan becomes 32
days delinquent, the borrower automatically receives a demand letter.
 
     If a mortgage loan becomes 60 days delinquent, it is automatically
transferred to the Accelerations and Modifications Department which, as
described below, has significant discretion to make recommendations to work out
the delinquency with the borrower or to forward the mortgage loan to the Default
Control Department to commence foreclosure proceedings. If the Accelerations and
Modifications Department determines that a workout is in the best interests of
the owner of the loan, but is unsuccessful, the mortgage loan is returned to the
Default Control Department.
 
     If a mortgage loan is returned, the pre-foreclosure committee will attempt
to determine whether sufficient equity exists in the mortgaged property to
warrant the commencement of foreclosure proceedings. That committee carefully
examines any such mortgage loan with an estimated loan-to-value ratio in excess
of 80% if the exposure to loss is greater than $5,000 and will review potential
environmental concerns. In addition, it may recommend further contact with the
borrower prior to initiating legal proceedings.
 
     If further contact with the borrower does not resolve the delinquency, the
Default Control Department will commence foreclosure proceedings. Thirty days
prior to a scheduled foreclosure, SMC will force place
 
                                      S-24
<PAGE>   27
 
insurance to reduce the exposure of the mortgaged property to damage. If title
to a mortgaged property is acquired by SMC on behalf of the holder of the
mortgage loan, responsibility will be transferred to the Property Management
Department to secure and protect the property and to commence efforts to sell
the mortgaged property.
 
  Accelerations and Modifications Department
 
     The Accelerations and Modifications Department is responsible for handling
all mortgage loan assumptions and requests for release of liability. As a
general rule, SMC will waive due-on-sale clauses, and permit assumptions of
mortgage loans provided that such actions are in the best interests of the
holder of the loan and SMC receives reimbursement for all related costs and
expenses. The ability of the Master Servicer to make such waivers or to permit
such assumptions is limited by the Pooling Agreement. See "Prepayment and Yield
Considerations -- Prepayment Considerations and Risks" herein.
 
     The Accelerations and Modifications Department also reviews the mortgage
loan file with respect to each mortgage loan referred to it by the Loan
Servicing Department or the Default Control Department. The Accelerations and
Modifications Department has significant discretion to modify and restructure
mortgage loans in a manner deemed to be in the holders' best interests taking
into consideration the need to preserve the value of the mortgaged properties.
Modifications to the mortgage loans may include extensions, reductions in the
interest rate, payment reductions, waiver of late charges, or other adjustments.
 
     Because the Accelerations and Modifications Department has significant
discretion with respect to restructuring the mortgage loans, SMC has formed a
pre-foreclosure committee comprised of certain of SMC's senior managers,
including the Accelerations and Modifications Department manager, the Default
Control Department manager, and in-house legal counsel. The pre-foreclosure
committee is required to approve modifications to a mortgage loan for which
foreclosure proceedings have been commenced by the Accelerations and
Modifications Department. The Underwriting Committee reviews all proposed
modifications of mortgage loans for which foreclosure proceedings have not
commenced. The documents for any approved modifications, forbearance agreements
and similar arrangements are prepared by SMC. The Accelerations and
Modifications Department will attempt to decide on a course of action within 72
hours and resolve any delinquency within two weeks. The borrower will be
contacted both verbally and by letter. The objective of the Accelerations and
Modifications Department is to return the mortgage loan to performing status.
 
     With respect to mortgage loans having delinquent property tax payments, the
Accelerations and Modifications Department may require the borrower to establish
an escrow account funded by higher monthly payments by the borrower for the
payments of insurance and taxes.
 
     A substantial majority of the modifications that are made by the
Accelerations and Modifications Department are made on current loans. In many
cases, borrowers are contacted by the Accelerations and Modifications Department
shortly after a mortgage loan's acquisition to, among other things, (i) convert
adjustable rate loans to fixed rate loans, (ii) extend the maturity of balloon
loans or convert such loans to fully amortizing loans, (iii) decrease the loan
term or (iv) make other modifications to create a fixed rate, first lien
product. The Pooling Agreement limits the Master Servicer from making
modifications of the Mortgage Loans. See "The Pooling and Servicing
Agreement -- Modification of Mortgage Loans" herein.
 
FORECLOSURE AND DELINQUENCY EXPERIENCE ON SMC'S SERVICING PORTFOLIO
 
     Historically, a variety of factors, including the appreciation of real
estate values, have limited SMC's loss and delinquency experience on its
portfolio of serviced mortgage loans.
 
     The following tables summarize the foreclosure and delinquency experience,
respectively, at the dates indicated of all mortgage loans (including loans
secured by unimproved land and commercial and multi-family properties) serviced
by SMC, including loans obtained by the Sellers in a manner similar to that
described herein under "The Mortgage Pool -- Acquisition Underwriting
Standards." There can be no assurance that the foreclosure or delinquency
experience on the Mortgage Loans will be comparable.
 
                                      S-25
<PAGE>   28
 
Furthermore, there can be no assurance that factors beyond SMC's control, such
as national or local economic conditions or downturns in the real estate markets
of its servicing areas, will not result in increased rates of delinquencies and
foreclosures in the future. In addition, the foregoing statistics are based on
all of the loans secured by real estate in SMC's servicing portfolio, including
commercial and unimproved land loans and loans with a variety of payment and
other characteristics that may not correspond to those of the Mortgage Loans.
The actual loss and delinquency experience on the Mortgage Loans will depend,
among other things, upon the value of the related Mortgaged Properties and the
ability of the borrowers to make required payments.

                      THE POOLING AND SERVICING AGREEMENT
 
GENERAL
 
     The Certificates will be issued pursuant to a Pooling and Servicing
Agreement, dated as of April 1, 1996 (the "Pooling Agreement"), among the
Sponsor, the Sellers, the Master Servicer and the Trustee. Reference is made to
the Prospectus for important additional information regarding the terms and
conditions of the Pooling Agreement and the Certificates. The following
summaries do not purport to be complete and are subject to, and are qualified in
their entirety by reference to, the provisions of the Pooling Agreement. When
particular provisions or terms used in the Pooling Agreement are referred to,
the actual provisions (including definitions of terms) are incorporated by
reference.
 
     The Mortgage Pass-Through Certificates, Series 1996-1 (the "Certificates")
will consist of the Class A-1, Class A-2, Class A-3 and Class A-4 Certificates
(collectively, the "Senior Certificates"), Class B-1, Class B-2, Class B-3 and
Class B-4 Certificates (collectively, the "Class B Certificates"), and the Class
R Certificates (the "Residual Certificates" and, together with the Class B
Certificates, the "Subordinate
 
                                      S-26
<PAGE>   29
 
Certificates"). Only the Class A-1, Class A-2, Class A-3, Class A-4, Class B-1
and Class B-2 Certificates (the "Offered Certificates") are offered hereby. The
Classes of Offered Certificates will have the respective initial Class
Certificate Balances (subject to the permitted variance) and Pass-Through Rates
set forth on the cover hereof.
 
     The "Class Certificate Balance" of any Class of Certificates as of any
Distribution Date, other than the Class R Certificates, is the initial Class
Certificate Balance thereof reduced by the sum of (i) all amounts previously
distributed to holders of the Certificates of such Class as payments of
principal, and (ii) the amount of Realized Losses (including Excess Losses)
allocated to such Class. The Class Certificate Balance of the Class R
Certificates will be equal to the aggregate of the Component Balances of the
related Components as described in "Description of the Certificates -- Residual
Certificates" herein.
 
   
     The Senior Certificates, other than the Class A-4 Certificates, will have
an initial aggregate Class Certificate Balance of approximately $79,862,360 and
will evidence in the aggregate an initial beneficial ownership interest of
approximately 65.0% in the Pool. The Class A-4 Certificates will evidence an
initial beneficial ownership interest of approximately 22.0% in the Pool. The
Class B-1, Class B-2, Class B-3, Class B-4 and Class R Certificates will each
evidence in the aggregate an initial beneficial ownership interest of
approximately 3.65%, 3.35%, 1.95%, 0.55% and 3.50%, respectively, in the Pool.
    
 
     The "Percentage Interest" of an Offered Certificate as of any date of
determination will be equal to the percentage obtained by dividing the
denomination of such Certificate by the initial Class Certificate Balance of the
related Class.
 
     The Book-Entry Certificates will be issuable in book-entry form only. The
Physical Certificates will be issued in fully registered certificated form. The
Physical Certificates offered hereby will be issued in minimum dollar
denominations of $500,000 and integral multiples of $1.00 in excess thereof. A
single Certificate of each Class may be issued in an amount different than
described above.
 
BOOK-ENTRY CERTIFICATES
 
     The Book-Entry Certificates will be issued in one or more certificates
which equal the aggregate principal balance of each such Class of Certificates
which will be held by a nominee of The Depository Trust Company (together with
any successor depository selected by the Sponsor, the "Depository"). Beneficial
interests in the Book-Entry Certificates will be indirectly held by investors
through the book-entry facilities of the Depository, as described herein.
Investors may hold such beneficial interests in the Book-Entry Certificates in
minimum denominations of $500,000 and in integral multiples of $1.00 in excess
thereof. The Sponsor has been informed by the Depository that its nominee will
be CEDE & Co. ("CEDE"). Accordingly, CEDE is expected to be the holder of record
of the Book-Entry Certificates. Except as described below, no person acquiring a
Book-Entry Certificate (each, a "beneficial owner") will be entitled to receive
a physical certificate representing such Certificate (a "Definitive
Certificate").
 
     The beneficial owner's ownership of a Book-Entry 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 Book-Entry Certificate will be recorded on the
records of the Depository (or of a participating firm that acts as agent for the
Financial Intermediary, whose interests 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 a Book-Entry
Certificate. Beneficial ownership of a Book-Entry Certificate may only be
transferred by compliance with the procedures of such Financial Intermediaries
and Depository participants.
 
     The Depository is a limited purpose trust company organized under the laws
of the State of New York, a member of the Federal Reserve System, a "Clearing
Corporation" within the meaning of the Uniform Commercial Code as in effect in
the State of New York and a "Clearing Agency" registered pursuant to Section 17A
of the Securities Exchange Act of 1934, as amended. The Depository performs
services for its participants, some of which (and/or their representatives) own
the Depository. In accordance with its normal
 
                                      S-27
<PAGE>   30
 
procedures, the Depository is expected to record the positions held by each
Depository participant in the Book-Entry Certificates, whether held for its own
account or as a nominee for another person. In general, beneficial ownership of
Book-Entry Certificates will be subject to the rules, regulations and procedures
governing the Depository and Depository participants as in effect from time to
time.
 
     Distributions on the Book-Entry Certificates will be made on each
Distribution Date by the Trustee to the Depository. 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 of the Book-Entry Certificates that it
represents 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 Book-Entry Certificates that it represents.
 
     Under a book-entry format, beneficial owners of the Book-Entry Certificates
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Trustee to CEDE. Because the Depository can only act on
behalf of Financial Intermediaries, the ability of a beneficial owner to pledge
Book-Entry Certificates to persons or entities that do not participate in the
Depository system, or otherwise take actions in respect of such Book-Entry
Certificates, may be limited due to the lack of physical certificates for such
Book-Entry Certificates. In addition, issuance of the Book-Entry Certificates in
book-entry form may reduce the liquidity of such Certificates in the secondary
market since certain potential investors may be unwilling to purchase
Certificates for which they cannot obtain physical certificates.
 
     None of the Sponsor, any Seller, the Master Servicer or the Trustee will
have any responsibility for any aspect of the records relating to or payments
made on account of beneficial ownership interests of the Book-Entry Certificates
held by CEDE, as nominee for DTC, or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests. In the event of the
insolvency of the Depository, a Depository participant or an indirect Depository
participant in whose name Book-Entry Certificates are registered, the ability of
the Beneficial Owners of such Book-Entry Certificates to obtain timely payment
may be impaired.
 
     Unless and until Definitive Certificates are issued, it is anticipated that
the only "Certificateholder" of the Book-Entry Certificates will be CEDE, as
nominee of the Depository. Beneficial owners of the Book-Entry Certificates will
not be Certificateholders, as that term is used in the Pooling Agreement.
Beneficial owners are only permitted to exercise the rights of
Certificateholders indirectly through Financial Intermediaries and the
Depository. Monthly and annual reports on the Pool provided by the Master
Servicer to CEDE, as nominee of the Depository, may be made available to
beneficial owners upon request, in accordance with the rules, regulations and
procedures creating and affecting the Depository, and to the Financial
Intermediaries to whose Depository accounts the Book-Entry Certificates of such
beneficial owners are credited.
 
     The Depository has advised the Sponsor and the Trustee that, unless and
until Definitive Certificates are issued, the Depository will take any action
permitted to be taken by the holders of the Book-Entry Certificates under the
Pooling Agreement only at the direction of one or more Financial Intermediaries
to whose Depository accounts the Book-Entry Certificates are credited, to the
extent that such actions are taken on behalf of Financial Intermediaries whose
holdings include such Book-Entry Certificates.
 
     Definitive Certificates will be issued to beneficial owners of the
Book-Entry Certificates, or their nominees, rather than to the Depository, only
if (a) the Depository or the Sponsor advises the Trustee in writing that the
Depository is no longer willing, qualified or able to discharge properly its
responsibilities as nominee and depository with respect to the Book-Entry
Certificates and the Sponsor or the Trustee is unable to locate a qualified
successor; (b) the Sponsor, at its sole option, elects to terminate a book-entry
system through the Depository; or (c) after the occurrence of an Event of
Default (as described in the accompanying Prospectus), beneficial owners having
Percentage Interests aggregating not less than 51% of all Percentage Interests
evidenced by each Class of the Book-Entry Certificates advise the Trustee and
the Depository through the Financial Intermediaries in writing that the
continuation of a book-entry system through the Depository (or a successor
thereto) is no longer in the best interests of beneficial owners.
 
                                      S-28
<PAGE>   31
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all beneficial
owners of the occurrence of such event and the availability through the
Depository of Definitive Certificates. Upon surrender by the Depository of the
global certificate or certificates representing the Book-Entry Certificates and
instructions for re-registration, the Trustee will issue the Definitive
Certificates, and thereafter the Trustee will recognize the holders of such
Definitive Certificates as Certificateholders under the Pooling Agreement.
 
ASSIGNMENT OF THE MORTGAGE LOANS
 
     In connection with the transfer and assignment of the Mortgage Loans to the
Trustee, the Sponsor will deliver or cause to be delivered to the Trustee, or a
custodian for the Trustee, among other things, with respect to each Mortgage
Loan, other than a Land Sale Contract, the original Mortgage Note endorsed
without recourse to the order of the Trustee (or its nominee) or a certificate
signed by an officer of the applicable Seller certifying that the related
original Mortgage Note has been lost, the original or certified copy of the
Mortgage with evidence of recording indicated thereon (except for any Mortgage
not returned from the public recording office, which will be delivered to the
Trustee as soon as the same is available to the Sponsor), an assignment in
recordable form of the Mortgage and, if applicable, any riders or modifications
to such Mortgage Note and Mortgage and, in the case of a Land Sale Contract, the
Land Sale Contract, an assignment in recordable form of the Land Sale Contract
and the related deed to the property in the name of the Trustee (collectively,
the "Mortgage File"). Assignments of the Mortgage Loans to the Trustee (or its
nominee) will be recorded in the appropriate public office for real property
records, except in states where, in the opinion of counsel acceptable to the
Trustee, such recording is not required to protect the Trustee's interests in
the Mortgage Loan against the claim of any subsequent transferee or any
successor to or creditor of the Sponsor or the Seller.
 
     The Trustee will promptly review each Mortgage File after the Closing Date
(or promptly after the Trustee's receipt of any document permitted to be
delivered after the Closing Date) and if any of the foregoing documents is found
to be missing or defective in any material respect and the applicable Seller
does not cure such omission or defect within 180 days of the Closing Date, such
Seller will on the Distribution Date in the month following the expiration of
such 180-day period either (i) repurchase the related Mortgage Loan (or any
property acquired in respect thereof) at a price (the "Purchase Price") equal to
100% of the unpaid principal balance of such Mortgage Loan plus accrued and
unpaid interest on such principal balance at the related interest rate paid on
the Mortgage Loan ("Mortgage Rate"), or (ii) substitute an Eligible Substitute
Mortgage Loan; however, such substitution is permitted only within two years of
the Closing Date and may not be made unless an opinion of counsel is provided to
the effect that such substitution will not disqualify the Pool as a REMIC or
result in a prohibited transaction tax under the Code. Any Eligible Substitute
Mortgage Loan generally will, on the date of substitution, among other
characteristics set forth in the Pooling Agreement, (i) have a principal
balance, after deduction of all Scheduled Payments due in the month of
substitution, not in excess of, and not more than 10% less than, the Scheduled
Principal Balance of the Deleted Mortgage Loan (the amount of any shortfall to
be deposited by the Seller and held for distribution to the Certificateholders
on the related Distribution Date (a "Substitution Adjustment Amount")), (ii)
have a Mortgage Rate not lower than, and not more than 2% per annum higher than,
that of the Deleted Mortgage Loan, (iii) have a Loan-to-Value Ratio not higher
than that of the Deleted Mortgage Loan, (iv) have a remaining term to maturity
not greater than (and not more than one year less than) that of the Deleted
Mortgage Loan, and (v) comply with all of the representations and warranties set
forth in the Pooling Agreement as of the date of substitution. This cure,
repurchase or substitution obligation constitutes the sole remedy available to
Certificateholders or the Trustee for omission of, or a material defect in, a
Mortgage Loan document. However, if Western should default in its obligation to
cure, repurchase or substitute for a Deleted Mortgage Loan, as discussed above,
Metropolitan shall have such obligation and if Old Standard should default in
such obligation, Summit shall have such obligation.

<PAGE>   32
 
PAYMENTS ON MORTGAGE LOANS; ACCOUNTS
 
     On or prior to the Closing Date, the Master Servicer will establish an
account (the "Collection Account") with SeaFirst National Bank, which shall be
maintained by the Master Servicer in trust for the benefit of
Certificateholders. Funds credited to the Collection Account may be invested for
the benefit and at the risk of the Master Servicer in Eligible Investments, as
defined in the Pooling Agreement, that are scheduled to mature on or prior to
the business day preceding the next Distribution Date. On or prior to the
business day immediately preceding each Distribution Date, the Master Servicer
shall withdraw from the Collection Account the amount of Available Funds and
shall deposit such Available Funds in an account established and maintained as a
separate trust account with the Trustee on behalf of Certificateholders (the
"Distribution Account").
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Expense Fees with respect to the Mortgage Pool are payable out of the
interest payments on each Mortgage Loan. The Expense Rate in respect of each
Mortgage Loan will be 0.758% per annum of the Scheduled Principal Balance of
such Mortgage Loan. The Expense Fees consist of (a) servicing compensation
payable to the Master Servicer in respect of its master servicing activities
(the "Master Servicing Fee"), and (b) fees paid to the Trustee. The Master
Servicing Fee will be 0.75% per annum of the Scheduled Principal Balance of each
Mortgage Loan as of the first day of the month of the related Distribution Date
(without taking into account any unscheduled receipts of principal during the
preceding calendar month). The Master Servicer is obligated to pay certain
ongoing expenses associated with the Pool and incurred by the Master Servicer in
connection with its responsibilities under the Pooling Agreement and such
amounts will be paid by the Master Servicer out of the Master Servicing Fee. The
amount of the Master Servicing Fee is subject to adjustment with respect to
prepaid Mortgage Loans, as described below under "-- Adjustment to the Master
Servicing Fee in Connection with Prepaid Mortgage Loans." The Master Servicer is
also entitled to receive all late payment fees, prepayment penalties, assumption
fees and other similar charges (including forbearance fees) and all reinvestment
income earned on amounts on deposit in the Collection Account.
 
ADJUSTMENT TO MASTER SERVICING FEE IN CONNECTION WITH PREPAID MORTGAGE LOANS
 
     When a Mortgage Loan is prepaid between Due Dates, the borrower is required
to pay interest on the amount prepaid only to the date of prepayment and not
thereafter. Prepayments received during a Due Period will be distributed to
Certificateholders on the Distribution Date following such Due Period. Pursuant
to the Pooling Agreement, the Master Servicing Fee for any month will be reduced
by an amount with respect to each such Mortgage Loan sufficient to pass through
to the Pool on such Distribution Date an amount equal to 30 days' interest at
the Mortgage Rate (net of the Master Servicing Fee Rate) for each such Mortgage
Loan up to a maximum amount equal to two-thirds of the Master Servicing Fee
otherwise payable on such Distribution Date. Any such shortfalls in interest as
a result of prepayments in excess of two-thirds of the amount of the Master
Servicing Fee for a month will reduce the amount of interest available to be
distributed to Certificateholders from what would have been the case in the
absence of such prepayments. See "Description of the
Certificates -- Distributions" herein.
 
ADVANCES
 
   
     Subject to the following limitations, the Master Servicer will be required
to advance prior to each Distribution Date from its own funds or funds in the
Collection Account that do not constitute Available Funds for such Distribution
Date, an amount equal to the aggregate of payments of principal and interest
(adjusted to the applicable Mortgage Rate (net of the Master Servicing Fee
Rate)) which were due during the related Due Period and which were delinquent on
the related Determination Date, together with an amount equivalent to interest
on each Mortgaged Property acquired by the Master Servicer through foreclosure,
forfeiture or deed-in-lieu of foreclosure in connection with a defaulted
Mortgage Loan ("REO Property") (any such advance, an "Advance"). With respect to
any Distribution Date, the "Determination Date" is three Business Days prior to
such Distribution Date.

<PAGE>   33
 
     With respect to any Mortgage Loan that is a Balloon Loan, in the event of
default in the Balloon Payment due on the maturity of such Mortgage Loan, the
Master Servicer will not advance such Balloon Payment. The Master Servicer will,
however, continue to advance each month, subject to the Master Servicer's
determination as to recoverability, an amount equal to interest on the principal
balance of such Mortgage Loan deemed to be due thereon after such default.
 
     Advances are intended to maintain a regular flow of scheduled interest and
principal payments on the Certificates rather than to guarantee or insure
against losses. The Master Servicer is obligated to make Advances with respect
to delinquent payments of principal of or interest on each Mortgage Loan (with
such payments of interest adjusted as described above) to the extent that such
Advances are, in its judgment, reasonably recoverable from future payments and
collections or insurance payments or proceeds from liquidation of the related
Mortgage Loan. If the Master Servicer determines on any Determination Date to
make an Advance, such Advance will be included with the distribution to
Certificateholders on the related Distribution Date. Any failure by the Master
Servicer to make an Advance as required under the Pooling Agreement with respect
to the Certificates will constitute an Event of Default thereunder, in which
case the Trustee or the successor servicer will be obligated to make any such
Advance, in accordance with the terms of the Pooling Agreement.
 
TERMINATION; OPTIONAL TERMINATION
 
     The circumstances under which the obligations created by the Pooling
Agreement will terminate in respect of the Certificates are described in "The
Pooling and Servicing Agreement -- Termination; Repurchase of Mortgage Loans and
Mortgage Certificates" in the Prospectus. The Master Servicer will have the
option to purchase all remaining Mortgage Loans and other assets in the Pool,
thereby effecting early retirement of the Certificates and causing the
termination of the Pool's status as a REMIC, but such option will not be
exercisable until such time as the Pool Principal Balance as of the Distribution
Date on which the purchase proceeds are to be distributed to Certificateholders
is less than 10% of the Cut-off Date Pool Principal Balance. Distributions in
respect of any such optional termination will be paid to Certificateholders in
order of their priority of distribution as described herein under "Description
of the Certificates -- Priority of Distributions Among Classes of Certificates."
The proceeds from such a distribution may not be sufficient to distribute the
full amount to which each Class is entitled if the purchase price is based in
part on the fair market value of the Mortgaged Property acquired upon
foreclosure of a Mortgage Loan and such fair market value is less than the
Scheduled Principal Balance of the related Mortgage Loan. In no event will the
trust created by the Pooling Agreement continue beyond the later of (a) the
optional purchase described above, (b) the expiration of 21 years from the death
of the survivor of the person named in the Pooling Agreement and (c) the
Distribution Date specified in the Pooling Agreement. The termination of the
Pool will be effected in a manner consistent with applicable federal income tax
regulations and the status of the Pool as a REMIC.
 
MODIFICATION OF MORTGAGE LOANS
 
     The Pooling Agreement permits the Master Servicer, within certain
limitations set forth therein, to agree to any modification, waiver, forbearance
or amendment of any term of any Mortgage Loan without the consent of the Trustee
or any Certificateholder. Any such modification, waiver, forbearance or
amendment is permissible only (i) if such Mortgage Loan is 90 days or more past
due or (ii) if the Master Servicer delivers to the Trustee an opinion of counsel
to the effect that such modification, waiver, forbearance or amendment would not
affect the Pool's status as a REMIC, and, in each case, such modification,
waiver, forbearance or amendment is likely to produce a greater recovery with
respect to such Mortgage Loan than would liquidation. In addition, with respect
to each Balloon Loan, the Master Servicer may extend the date on which any
Balloon Payment is due by up to six months, (i) if the Mortgagor defaults on its
obligation to pay the Balloon Payment when due, (ii) if, within 90 days of the
date on which the Balloon Payment is due, the Master Servicer has received
notice that the Mortgagor under such Balloon Loan intends to default on such
Balloon Payment or (iii) if the Master Servicer delivers to the Trustee an
opinion of counsel to the effect that such modification, waiver, forbearance or
amendment would not affect the Pool's status as a REMIC, and, in each case, such
modification, waiver, forbearance or amendment is likely to produce a greater
recovery with respect to such
 
                                      S-31
<PAGE>   34
 
Balloon Loan than would liquidation. The Master Servicer shall notify the
Trustee in writing of any modification, waiver, forbearance or amendment of any
term of any Mortgage Loan and the date thereof and shall deliver to the Trustee
an original counterpart of the agreement relating to such modification, waiver,
forbearance or amendment within ten Business Days of the execution thereof.
 
OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS
 
     Subject to certain conditions specified in the Pooling Agreement, the
Master Servicer has the option, but is not obligated, (i) to purchase from the
Pool any Mortgage Loan 90 days or more delinquent at the Purchase Price for such
Mortgage Loan or (ii) to offer to sell any such Mortgage Loan in a commercially
reasonable manner if the Master Servicer determines that such a sale would
produce a greater recovery on a present value basis than would liquidation of
the related Mortgaged Property.
 
HAZARD INSURANCE
 
     The Master Servicer will cause to be maintained with respect to each
Mortgage Loan a hazard insurance policy providing coverage against loss by fire
and other hazards as are customary in the area in which the related Mortgaged
Property is located. If the Mortgage or Land Sale Contract permits the holder
thereof to dictate the amount of hazard insurance to be in place with respect
thereto, then the Master Servicer will assure that such amount of insurance
would be consistent with the ordinary practices of prudent institutional
mortgage lenders and loan servicers servicing mortgage loans comparable to such
Mortgage Loan. Notwithstanding the foregoing, the Pooling Agreement will require
that the Master Servicer cause to be maintained an amount of hazard insurance
not less than the Scheduled Principal Balance of such Mortgage Loan. With
respect to any Mortgage Loan with respect to which the related Mortgaged
Property has been acquired upon forfeiture, foreclosure or deed-in-lieu of
foreclosure, the Master Servicer shall cause to be maintained hazard insurance
coverage at least equal to the Scheduled Principal Balance of the related
Mortgage Loan at the time of such acquisition.
 
                        DESCRIPTION OF THE CERTIFICATES
 
PRIORITY OF DISTRIBUTIONS AMONG CLASSES OF CERTIFICATES
 
     As more fully described herein, distributions will be made on the
Certificates on each Distribution Date from Available Funds in the following
order of priority: (i) to interest on each Class of Senior Certificates; (ii) to
principal of the Classes of Senior Certificates then entitled to receive
distributions of principal, in the order and subject to the priorities set forth
herein under "Description of the Certificates -- Principal," up to the maximum
amount of principal to be distributed on such Classes on such Distribution Date;
(iii) to interest and then to principal of the Class B-1 and Class B-2
Certificates, in that order, up to the maximum amount of interest and principal
to be distributed on each such Class on such Distribution Date; (iv) to interest
on the Class B-3 Certificates; (v) to interest on the Class B-4 Certificates;
(vi) to interest on the Class Z/IO Component of the Class R Certificates (except
such interest will be added to the Component Balance thereof up to and including
the Accretion Termination Date); (vii) after the Offered Certificates are paid
in full, sequentially, to principal of the Class B-3, Class B-4 and the Class R
Certificates, in that order, up to the maximum amount of principal to be
distributed on each such Class on such Distribution Date; and (viii) to the
Class R Certificates, any remaining Available Funds.
 
DISTRIBUTIONS
 
     Distributions of principal and interest to holders of the Offered
Certificates will be made on each Distribution Date to the extent of Available
Funds therefor as described above under "-- Priority of Distributions Among
Classes of Certificates" to holders of record of such Offered Certificates on
the last day of the preceding month (the "Record Date"), except that the final
distribution in respect of any Class of Offered Certificates will be made only
upon presentation and surrender of such Certificates at the office or agency
appointed by the Trustee for that purpose in New York, New York.
 
                                      S-32
<PAGE>   35
 
     Distributions on each Distribution Date will be made by check mailed to the
address of the person entitled thereto as it appears on the applicable
certificate register or, in the case of a Certificateholder who holds a Class of
Certificates with aggregate denominations of $1,000,000 or more and who has so
notified the Trustee in writing in accordance with the Pooling Agreement, by
wire transfer in immediately available funds to the account of such
Certificateholder at a bank or other depository institution having appropriate
wire transfer facilities; provided, however, that the final distribution in
retirement of the Certificates will be made only upon presentment and surrender
of such Certificates at the Corporate Trust Office of the Trustee.
 
     The aggregate amount of funds available in the Distribution Account on a
Distribution Date for distribution on the Certificates is equal to "Available
Funds". "Available Funds" with respect to any Distribution Date is the sum of
(i) all scheduled installments of interest (net of related Expense Fees) and
principal for each Mortgage Loan due on the Scheduled Due Date in the month in
which such Distribution Date occurs and received prior to the related
Determination Date, together with any Advances in respect thereof, (ii) all
proceeds of any insurance policies with respect to the Mortgage Loans, to the
extent such proceeds are not applied to the restoration of the related Mortgaged
Property or released to the Mortgagor in accordance with the Master Servicer's
normal servicing procedures (collectively, "Insurance Proceeds") and all other
cash amounts received and retained in connection with the liquidation of
defaulted Mortgage Loans, by foreclosure, forfeiture or otherwise ("Liquidation
Proceeds") during the related Due Period (in each case, net of unreimbursed
expenses incurred in connection with a liquidation, forfeiture or foreclosure
and unreimbursed Advances, if any), (iii) all partial or full prepayments on
Mortgage Loans received during the related Due Period and (iv) the amount
required to be paid in respect of a Mortgage Loan that became required to be
repurchased or any Substitution Adjustment Amounts in connection with any
substitution of a Mortgage Loan, in either case during the related Due Period,
reduced by amounts in reimbursement for Advances previously made and other
amounts as to which the Master Servicer is entitled to be reimbursed from the
Collection Account pursuant to the Pooling Agreement.
 
     The Trustee will forward with each distribution on a Distribution Date to
each Offered Certificateholder and the Master Servicer a statement or statements
setting forth, among other things, (i) the amount of such distribution allocable
to principal and (ii) the amount of such distribution allocable to interest.
Such amounts will be expressed as a dollar amount per $1,000 of Class
Certificate Balance. See "Description of Certificates--Reports to
Certificateholders" in the Prospectus for a detailed description of the
information to be included in such statements.
 
     Interest.  On each Distribution Date, each Class of Offered Certificates,
to the extent of Available Funds on such Distribution Date applied in the order
described above under "-- Priority of Distributions Among Classes of
Certificates", will be entitled to receive an amount allocable to interest equal
to the sum of (i) one month's interest at the applicable Pass-Through Rate on
the respective Class Certificate Balance and (ii) the sum of the amounts, if
any, by which the amount described in clause (i) above on each prior
Distribution Date exceeded the amount actually distributed as interest on such
prior Distribution Dates and not subsequently distributed ("Unpaid Interest
Amounts").
 
     The interest entitlement for each Class of Certificates or Component
thereof will be reduced by the amount of "Net Interest Shortfalls" for such
Distribution Date. With respect to any Distribution Date, the "Net Interest
Shortfall" is equal to the sum of (i) the amount of interest which would
otherwise have been received with respect to any Mortgage Loan that was the
subject of (a) a Relief Act Reduction or (b) after the coverage provided by the
Subordinate Certificates is exhausted for such type of loss, a Special Hazard
Loss, Fraud Loss or a Bankruptcy Loss and (ii) any Net Prepayment Interest
Shortfalls. Net Interest Shortfalls on any Distribution Date will be allocated
pro rata among all Classes of Certificates or Component thereof entitled to
receive distributions of interest on such Distribution Date, based on the amount
of interest each such Class of Certificates or Component would otherwise be
entitled to receive or accrete on such Distribution Date, before taking into
account any reduction in such amounts resulting from such Net Interest
Shortfalls. A "Relief Act Reduction" is a reduction in the amount of monthly
interest payment on a Mortgage Loan pursuant to the Soldiers' and Sailors' Civil
Relief Act of 1940. See "Certain Legal Aspects of Mortgage Loans -- Soldiers'
and Sailors' Civil Relief Act" in the Prospectus. With respect to any
Distribution Date, "Net Prepayment Interest Shortfall" is the amount by which
the aggregate of Prepayment Interest Shortfalls
 
                                      S-33
<PAGE>   36
 
experienced by the Mortgage Loans during the related Due Period exceeds
two-thirds of the Master Servicing Fee for such period. A "Prepayment Interest
Shortfall" is the amount by which interest received in connection with a
prepayment of principal on a Mortgage Loan is less than one month's interest at
the related Mortgage Rate (net of the related Master Servicing Fee) on the
Scheduled Principal Balance of the related Mortgage Loan that is prepaid.
 
     Accrued interest to be distributed on any Distribution Date will be
calculated, in the case of each Class of Offered Certificates, on the basis of
the related Class Certificate Balance immediately prior to such Distribution
Date. Interest on such Classes will be calculated and payable on the basis of a
360-day year divided into twelve 30-day months.
 
     In the event that, on a particular Distribution Date, Available Funds on
such Distribution Date applied in the order described above under "-- Priority
of Distributions Among Classes of Certificates," are not sufficient to make a
full distribution of the interest entitlement to holders of the Offered
Certificates, interest will be distributed on each Class of Offered Certificates
of equal priority in proportion to the amount of interest each such Class would
otherwise have been entitled to receive in the absence of such shortfall. The
amount of any resulting shortfall will be carried forward and added to the
amount holders of each such Class of Offered Certificates will be entitled to
receive on the next Distribution Date. Such a shortfall could occur, for
example, if losses realized on the Mortgage Loans were exceptionally high or
were concentrated in a particular month. Any such amount so carried forward will
not bear interest.
 
     Accretion Amount.  On each Distribution Date up to and including the
Accretion Termination Date, distributions of interest allocable to the Class
Z/IO Component (the "Accretion Amount") will be added to the Component Balance
thereof and the amount of such interest will be distributed on such Distribution
Date as principal of one or more Classes of Offered Certificates in the
following order of priority as set forth below:
 
          (i) sequentially, to the Class A-1, Class A-2 and Class A-3
     Certificates, in that order, until the respective Class Certificate
     Balances have been reduced to zero; and
 
          (ii) concurrently, to the Class A-4, Class B-1 and Class B-2
     Certificates, pro rata, based on the respective Class Certificate Balances
     on such Distribution Date.
 
     For a description of the amount of interest the Class Z/IO Component is
entitled to receive on any Distribution Date, see "-- Residual Certificates."
Distributions of interest allocable to the Class Z/IO Component will cease to
accrete on the Component Balance thereof and be payable as a current
distribution of interest thereon on each Distribution Date after the Class
Certificate Balance of each Class of Offered Certificates has been reduced to
zero (the "Accretion Termination Date").
 
     Principal Distributions.  On each Distribution Date prior to the Senior
Credit Support Depletion Date, to the extent of Available Funds remaining after
distribution of interest on each Class of Senior Certificates, the Senior
Principal Distribution Amount and the Class A-4 Principal Distribution Amount
will be distributed concurrently as described below, any shortfall being
allocated pro rata based on such amounts in the absence of any shortfall.
However, on each Distribution Date on and after the Senior Credit Support
Depletion Date, Available Funds remaining after the distribution of interest on
the Senior Certificates will be distributed, concurrently, as principal of all
of the Classes of Senior Certificates then outstanding, pro rata, in accordance
with their respective Class Certificate Balances immediately prior to such
Distribution Date. The "Senior Credit Support Depletion Date" is the date on
which the Class Certificate Balance of each Class of Subordinate Certificates
has been reduced to zero.
 
     Senior Principal Distribution Amount.  On each Distribution Date prior to
the Senior Credit Support Depletion Date, an amount up to the amount of the
Senior Principal Distribution Amount for such Distribution Date will be
distributed as principal, sequentially, to the Class A-1, Class A-2 and Class
A-3 Certificates, in that order, until the Class Certificate Balance thereof has
been reduced to zero.
 
     The Senior Principal Distribution Amount for any Distribution Date will
equal the sum of (i) the Senior Percentage of (a) the principal portion of the
Scheduled Payment due on each Mortgage Loan on the Scheduled Due Date in the
month of such Distribution Date, (b) the principal portion of the purchase price
of
 
                                      S-34
<PAGE>   37
 
each Mortgage Loan that was repurchased by the Seller or another person pursuant
to the Pooling Agreement with respect to such Distribution Date, (c) the
Substitution Adjustment Amount in connection with any Deleted Mortgage Loan
received with respect to such Distribution Date and (d) any Insurance Proceeds
or Liquidation Proceeds allocable to recoveries of principal of Mortgage Loans
that are not yet Liquidated Mortgage Loans received during the related Due
Period, (ii) with respect to each Mortgage Loan that became a Liquidated
Mortgage Loan during the related Due Period either (A) the Senior Prepayment
Percentage, if the Senior Prepayment Percentage is less than 100%, or, if the
Senior Prepayment Percentage equals 100%, the percentage obtained by dividing
the Senior Percentage by the sum of the Senior Percentage and the Class A-4
Percentage or (B) if an Excess Loss was sustained with respect to such
Liquidated Mortgage Loan during such Due Period, the Senior Percentage, of the
Liquidation Proceeds allocable to principal received with respect to such
Mortgage Loan, and (iii) the Senior Prepayment Percentage of all partial and
full principal prepayments by borrowers (including Balloon Payments) received
during the related Due Period for such Distribution Date; provided, however,
that if a Bankruptcy Loss that is an Excess Loss is sustained with respect to a
Mortgage Loan that is not a Liquidated Mortgage Loan, the Senior Principal
Distribution Amount will be reduced on the related Distribution Date by the
Senior Percentage of the principal portion of such Bankruptcy Loss.
 
     "Scheduled Principal Balance" of a Mortgage Loan as of any Scheduled Due
Date is the unpaid principal balance of such Mortgage Loan as specified in the
amortization schedule (before any adjustment to such schedule by reason of
moratorium or similar waiver or grace period) for such Scheduled Due Date, after
giving effect to any previous partial principal payments and to the payment of
principal due on such Scheduled Due Date and irrespective of any delinquency in
payment by the Mortgagor. The "Pool Principal Balance" will equal the aggregate
of the Scheduled Principal Balances of all Mortgage Loans. With respect to any
Distribution Date, the "Due Date" for a Mortgage Loan is the day of the calendar
month in the related Due Period on which the Scheduled Payment with respect
thereto is due although the amortization schedules prepared for each Mortgage
Loan assumes that each related Scheduled Payment is due on the last day of the
Due Period in which such Due Date occurs (each, a "Scheduled Due Date"). With
respect to any Distribution Date, the "Due Period" is the period commencing on
the second day of the preceding calendar month and ending on the first day of
the calendar month of such Distribution Date.
 
     The "Senior Percentage" for any Distribution Date is the percentage
equivalent of a fraction the numerator of which is the aggregate of the Class
Certificate Balances of each Class of Senior Certificates (other than the Class
A-4 Certificates) immediately prior to such date and the denominator of which is
the aggregate of the Class Certificate Balances of all Classes of Certificates
(other than the Class B-3, Class B-4 and Class R Certificates) immediately prior
to such date. The "Subordinate Percentage" for any Distribution Date will be
calculated as the difference between 100% and the sum of the Senior Percentage
and the Class A-4 Percentage for such Distribution Date.
 
     The Senior Prepayment Percentage for any Distribution Date occurring during
the five years beginning on the first Distribution Date will equal 100%.
Thereafter, the Senior Prepayment Percentage will, except as described below, be
subject to gradual reduction as described in the following paragraph. This
disproportionate allocation of certain unscheduled payments in respect of
principal (including Balloon Payments) will have the effect of accelerating the
amortization of the Senior Certificates (other than the Class A-4 Certificates)
while, in the absence of Realized Losses, increasing the interest in the Pool
Principal Balance evidenced by the Class A-4 Certificates and the Subordinate
Certificates. Increasing the respective interests of the Class A-4 Certificates
and the Subordinate Certificates relative to that of the Senior Certificates is
intended to preserve the availability of the subordination provided by the
Subordinate Certificates.
 
     The Senior Prepayment Percentage for any Distribution Date occurring on or
after the fifth anniversary of the first Distribution Date will be as follows:
for any Distribution Date in the first year thereafter, the Senior Percentage
plus 70% of the sum of the Class A-4 Percentage and the Subordinate Percentage
for such Distribution Date; for any Distribution Date in the second year
thereafter, the Senior Percentage plus 60% of the sum of the Class A-4
Percentage and the Subordinate Percentage for such Distribution Date; for any
Distribution Date in the third year thereafter, the Senior Percentage plus 40%
of the sum of the Class A-4 Percentage and the Subordinate Percentage for such
Distribution Date; for any Distribution Date in the fourth
 
                                      S-35
<PAGE>   38
 
year thereafter, the Senior Percentage plus 20% of the sum of the Class A-4
Percentage and the Subordinate Percentage for such Distribution Date; and for
any Distribution Date thereafter, the Senior Percentage for such Distribution
Date (unless on any of the foregoing Distribution Dates the Senior Percentage
exceeds the initial Senior Percentage, in which case the Senior Prepayment
Percentage for such Distribution Date will once again equal 100%).
Notwithstanding the foregoing, no decrease in the Senior Prepayment Percentage
will occur if as of the first Distribution Date as to which any such decrease
applies (i) the outstanding principal balance of all Mortgage Loans delinquent
60 days or more, including Mortgage Loans in foreclosure and REO (averaged over
the preceding six month period), as a percentage of the aggregate principal
balance of the Subordinate Certificates (averaged over the preceding six month
period), is equal to or greater than 50% or (ii) cumulative Realized Losses with
respect to the Mortgage Loans exceed (a) with respect to the Distribution Date
on the fifth anniversary of the first Distribution Date, 30% of the aggregate of
the Class Certificate Balances of the Subordinate Certificates as of the Closing
Date (the "Original Subordinate Principal Balance"), (b) with respect to the
Distribution Date on the sixth anniversary of the first Distribution Date, 35%
of the Original Subordinate Principal Balance, (c) with respect to the
Distribution Date on the seventh anniversary of the first Distribution Date, 40%
of the Original Subordinate Principal Balance, (d) with respect to the
Distribution Date on the eighth anniversary of the first Distribution Date, 45%
of the Original Subordinate Principal Balance, and (e) with respect to the
Distribution Date on the ninth anniversary of the first Distribution Date, 50%
of the Original Subordinate Principal Balance.
 
     The "Combined Prepayment Percentage" as of any Distribution Date will be
calculated as the difference between 100% and the Senior Prepayment Percentage
for such date. The "Class A-4 Prepayment Percentage" as of any Distribution Date
will be calculated as the product of (i) a fraction, expressed as a percentage,
the numerator of which is the Class Certificate Balance of the Class A-4
Certificates immediately prior to such Distribution Date and the denominator of
which is the aggregate of the Class Certificate Balances of the Class A-4
Certificates and the Subordinate Certificates (other than the Class B-3, Class
B-4 and Class R Certificates) immediately prior to such Distribution Date and
(ii) the Combined Prepayment Percentage. The "Subordinate Prepayment Percentage"
as of any Distribution Date will be calculated as the difference between the
Combined Prepayment Percentage and the Class A-4 Prepayment Percentage for such
date.
 
     If on any Distribution Date the allocation to any Class of Senior
Certificates (other than the Class A-4 Certificates) then entitled to
distributions of full and partial principal prepayments and other amounts in the
percentage required above would reduce the outstanding Class Certificate Balance
of such Class below zero, the distribution to such Class of Certificates of the
Senior Prepayment Percentage of such amounts for such Distribution Date will be
limited to the percentage necessary to reduce the related Class Certificate
Balance to zero.
 
     Class A-4 Principal Distribution Amount.  On each Distribution Date prior
to the Senior Credit Support Depletion Date, to the extent of funds available
therefor, holders of the Class A-4 Certificates will be entitled to receive a
principal distribution up to the amount of the Class A-4 Principal Distribution
Amount for such Distribution Date.
 
     The Class A-4 Principal Distribution Amount for any Distribution Date will
equal the sum of (i) the Class A-4 Percentage of (a) the principal portion of
the Scheduled Payment due on each Mortgage Loan on the Scheduled Due Date in the
month of such Distribution Date, (b) the principal portion of the purchase price
of each Mortgage Loan that was repurchased by the Seller or another person
pursuant to the Pooling Agreement with respect to such Distribution Date, (c)
the Substitution Adjustment Amount in connection with any Deleted Mortgage Loan
received with respect to such Distribution Date and (d) any Insurance Proceeds
or Liquidation Proceeds allocable to recoveries of principal of Mortgage Loans
that are not yet Liquidated Mortgage Loans received during the related Due
Period, (ii) with respect to each Mortgage Loan that became a Liquidated
Mortgage Loan during the calendar month preceding the month of such Distribution
Date, either (A) the Class A-4 Prepayment Percentage, if the Class A-4
Prepayment Percentage is greater than 0%, or, if the Class A-4 Prepayment
Percentage equals 0%, the percentage obtained by dividing the Class A-4
Percentage by the sum of the Senior Percentage and the Class A-4 Percentage or
(B) if any Excess Loss was sustained with respect to such Liquidated Mortgage
Loan during such Due Period, the Class A-4 Percentage, of the Liquidation
Proceeds allocable to principal received with respect to such
 
                                      S-36
<PAGE>   39
 
Mortgage Loan, and (iii) the Class A-4 Prepayment Percentage of all partial and
full principal prepayments by borrowers (including Balloon Payments) received
during the related Due Period; provided, however, that if a Bankruptcy Loss that
is an Excess Loss is sustained with respect to a Mortgage Loan that is not a
Liquidated Mortgage Loan, the Class A-4 Principal Distribution Amount will be
reduced on the related Distribution Date by the Class A-4 Percentage of the
principal portion of such Bankruptcy Loss.
 
     The "Class A-4 Percentage" for any Distribution Date is the percentage
equivalent of a fraction the numerator of which is the Class Certificate Balance
of the Class A-4 Certificates immediately prior to such date and the denominator
of which is the aggregate of the Class Certificate Balances of all Classes of
Certificates (other than the Class B-3, Class B-4 and Class R Certificate)
immediately prior to such Distribution Date.
 
     If on any Distribution Date the allocation to the Class A-4 Certificates
would reduce the outstanding Class Certificate Balance of the Class A-4
Certificates below zero, the distribution to the Class A-4 Certificates of the
Class A-4 Prepayment Percentage of such amounts for such Distribution Date will
be limited to the percentage necessary to reduce the Class Certificate Balance
to zero.
 
     Subordinate Principal Distribution Amount.  On each Distribution Date, to
the extent of Available Funds therefor, the Subordinate Principal Distribution
Amount for such Distribution Date, will be distributed as principal of the
Classes of Subordinate Certificates, other than the Class B-3, Class B-4 and
Class R Certificates. Each Class of Subordinate Certificates (other than the
Class B-3, Class B-4 and Class R Certificates) will be entitled to receive its
pro rata share of the Subordinate Principal Distribution Amount (based on its
respective Class Certificate Balance), in each case to the extent of the amount
available from Available Funds for distribution of principal on such Class.
Distributions of principal of the Subordinate Certificates (other than the Class
B-3, Class B-4 and Class R Certificates) will be made on each Distribution Date
sequentially first to the Class B-1 Certificates and then to the Class B-2
Certificates, until each such Class has received its respective pro rata share
for such Distribution Date. The Class B-3, Class B-4 and Class R Certificates
are not entitled to receive distributions of principal until the Offered
Certificates have been retired.
 
     The Subordinate Principal Distribution Amount for any Distribution Date
will equal the sum of (i) the Subordinate Percentage of (a) the principal
portion of the Scheduled Payment due on each Mortgage Loan on the Scheduled Due
Date in the month of such Distribution Date, (b) the principal portion of the
purchase price of each Mortgage Loan that was repurchased by the Seller or
another person pursuant to the Pooling Agreement with respect to such
Distribution Date, (c) the Substitution Adjustment Amount in connection with any
Deleted Mortgage Loan received with respect to such Distribution Date and (d)
any Insurance Proceeds or Liquidation Proceeds allocable to recoveries of
principal of Mortgage Loans that are not yet Liquidated Mortgage Loans received
during the related Due Period, (ii) with respect to each Mortgage Loan that
became a Liquidated Mortgage Loan during the related Due Period, Liquidation
Proceeds allocable to principal received with respect to such Mortgage Loan,
after application of amounts pursuant to clause (ii) of the definition of Senior
Principal Distribution Amount and pursuant to clause (ii) of the definition of
the Class A-4 Principal Distribution Amount, up to the Subordinate Percentage of
the Scheduled Principal Balance of such Mortgage Loan and (iii) the Subordinate
Prepayment Percentage of all partial and full principal prepayments by borrowers
(including Balloon Payments) received during the related Due Period for such
Distribution Date.
 
     Class B-3, Class B-4 and Class R Certificates Principal Distributions.  On
each Distribution Date after the Offered Certificates are paid in full, all
Available Funds, as calculated in the Pooling Agreement, remaining after the
distribution of interest to the Class B-3, Class B-4 Certificates and Class R
Certificates will be distributed sequentially to the Class B-3, Class B-4 and
Class R Certificates, in that order, as principal until the respective Class
Certificate Balance thereof has been reduced to zero.

(1) The Class PO Component will be a principal only component and will not bear
     interest.
(2) The initial Component Balance of the Class Z/IO Component will be zero.
     However, up to and including the Accretion Termination Date, distributions
     of interest allocable to the Class Z/IO Component will be added to the
     Component Balance thereof. On each Distribution Date after the Accretion
     Termination Date, distributions of interest allocable to the Class Z/IO
     Component for the preceding month will be paid currently as a distribution
     of interest to the holders of the related Class to the extent of Available
     Funds available therefor.
   
(3) On each Distribution Date the holders of the Class Z/IO Component will be
     entitled to receive or have accreted to their Component Balance, to the
     extent of Available Funds therefor, an amount of interest equal to the sum
     of (a) with respect to each Mortgage Loan with a Mortgage Rate in excess of
     9.008%, the product of (i) the Scheduled Principal Balance for such
     Mortgage Loan as of the Scheduled Due Date in the month of such
     Distribution Date and (ii) the excess of such Mortgage Rate thereon over
     9.008% and (b) with respect to each Class of Offered Certificates, the
     product of (i) the Class Certificate Balance of such Class for such
     Distribution Date and (ii) the excess of 8.25% over the related Pass-
     Through Rate, (subject to reduction for Net Interest Shortfalls as
     described herein under "-- Distributions") and (c) the sum of the amounts,
     if any, by which the amount described in clauses (a) and (b) above on each
     prior Distribution Date exceeded the amount actually distributed or
     accreted as interest on such prior Distribution Dates and not subsequently
     distributed or accreted.
    
 
     The Class R Certificates will receive principal distributions as described
above after all other Classes of Certificates have been paid in full. See
"-- Distributions -- Class B-3, Class B-4 and Class R Certificates Principal
Distributions" herein.
 
     The "Component Balance" with respect to any Component as of any
Distribution Date is the initial Component Balance thereof on the Closing Date,
(A) reduced by all amounts applied and losses allocated in reduction of the
principal balance of such Component on previous Distribution Dates, and (B) in
the case of the Class Z/IO Component, increased by all interest accrued and
added to the Component Balance thereof prior to such Distribution Date.
 
     The Components comprising the Class R Certificates will not be separately
transferable from such Class.
 
     In addition to the principal and interest distributions described above for
the Components of the Class R Certificates, on each Distribution Date, the
holders of the Class R Certificates will be entitled to receive the Available
Funds remaining after all Classes of Certificates, including the Class R
Certificates, receive their respective interest and principal distributions, if
any, on such Distribution Date. See "Description of the
Certificates -- Distributions" herein.
 
ALLOCATION OF LOSSES
 
     On each Distribution Date, any Realized Loss, other than any Excess Loss,
will be allocated first to the Residual Certificates, until the Class
Certificate Balance of such Class has been reduced to zero, second, to the other
Classes of Subordinate Certificates, in the reverse order of their numerical
Class designations (beginning with such Class of Subordinate Certificates then
outstanding with the highest numerical Class designation), in each case until
the Class Certificate Balance of the respective Class of Certificates has been
reduced to zero, and then to the Senior Certificates, pro rata, based upon their
respective Class Certificates Balances.
 
                                      S-38
<PAGE>   41
 
     On each Distribution Date, Excess Losses will be allocated pro rata among
the Classes of Senior Certificates and the Subordinate Certificates based upon
their respective Class Certificate Balances.
 
     For purposes of allocating Realized Losses and Excess Losses to the Class R
Certificates, such losses shall be allocated to the Components thereof, pro
rata, based upon their respective Component Balances.
 
     Because principal distributions are paid to certain Classes of Senior
Certificates before other Classes of Senior Certificates, holders of such Senior
Certificates that are entitled to receive principal later bear a greater risk of
being allocated Realized Losses on the Mortgage Loans than holders of Classes
that are entitled to receive principal earlier.
 
     In general, a "Realized Loss" means, with respect to a Liquidated Mortgage
Loan, the amount by which the remaining unpaid principal balance of the Mortgage
Loan exceeds the amount of Liquidation Proceeds applied to the principal balance
of the Mortgage Loan. "Excess Losses" are (i) Special Hazard Losses in excess of
the Special Hazard Loss Coverage Amount, (ii) Bankruptcy Losses in excess of the
Bankruptcy Loss Coverage Amount and (iii) Fraud Losses in excess of the Fraud
Loss Coverage Amount. "Bankruptcy Losses" are losses that are incurred as a
result of Debt Service Reductions and Deficient Valuations. "Special Hazard
Losses" are Realized Losses in respect of Special Hazard Mortgage Loans. "Fraud
Losses" are Realized Losses sustained on a Liquidated Mortgage Loan by reason of
a default arising from fraud, dishonesty or misrepresentation. See "Credit
Enhancement -- Subordination of Certain Classes" herein. Any Realized Loss
resulting from flood damage to a Mortgaged Property, which, at the time of
origination, was located in an area identified by FEMA as a flood zone for which
a federally regulated or an insured lender would be required to obtain flood
insurance, will not reduce the Special Hazard Loss Coverage Amount and will be
allocated as a Realized Loss (not as an Excess Loss) as described above.
 
     A "Liquidated Mortgage Loan" is a defaulted Mortgage Loan as to which the
Master Servicer has determined that all recoverable liquidation and insurance
proceeds have been received. A "Special Hazard Mortgage Loan" is a Liquidated
Mortgage Loan as to which the ability to recover the full amount due thereunder
was substantially impaired by a hazard not insured against under a standard
hazard insurance policy of the type described in the Prospectus under "Credit
Support -- Special Hazard Insurance Policies." See "Credit
Enhancement -- Subordination of Certain Classes" herein.
 
LAST SCHEDULED DISTRIBUTION DATE
 
     The Last Scheduled Distribution Date for each Class of Offered Certificates
is the latest date on which the Class Certificate Balance is expected to be
reduced to zero, and has been calculated on the basis of the assumptions
described above under "Prepayment and Yield Considerations -- Assumptions
Relating to Tables" except for the following additional assumption: no
prepayments occur on the Mortgage Loans. Since the rate of distributions in
reduction of the Class Certificate Balance on each Class of Offered Certificates
will depend on the rate of payment (including prepayments) of the Mortgage Loans
as well as the frequency and severity of losses experienced by the Pool, the
Class Certificate Balance of any such Class could reach zero significantly
earlier or later than its Last Scheduled Distribution Date. The rate of payments
on the Mortgage Loans will depend on their particular characteristics, as well
as on prevailing interest rates from time to time and other economic factors,
and no assurance can be given as to the actual payment experience of the
Mortgage Loans. See "Maturity, Prepayment Considerations and Weighted Average
Life of Certificates" in the Prospectus.
 
THE TRUSTEE
 
     The Bank of New York will be the Trustee under the Pooling Agreement. The
Sponsor and the Master Servicer may maintain other banking relationships in the
ordinary course of business with the Trustee. Offered Certificates may be
surrendered at the Corporate Trust Office of the Trustee located at 101 Barclay
Street, 12E, New York, New York 10286, Attention: Corporate Trust Administration
or at such other addresses as the Trustee may designate from time to time.

<PAGE>   42
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
GENERAL
 
     Delinquencies on the Mortgage Loans which are not advanced by or on behalf
of the Master Servicer (because amounts, if advanced, would be nonrecoverable),
will adversely affect the yield on the Certificates. Because of the priority of
distributions, shortfalls resulting from delinquencies not so advanced will be
borne first by the Subordinate Certificates (in the reverse order of their
priority of payment as described herein under "Description of the
Certificates -- Priority of Distributions Among Classes of Certificates"), and
then by the Senior Certificates.
 
     Net Interest Shortfalls will adversely affect the yields on the Offered
Certificates. In addition, although all losses initially will be borne by the
Subordinate Certificates, as described herein under "Description of the
Certificates -- Allocation of Losses", Excess Losses will be borne by all
Classes of Certificates in the manner set forth in such section. As a result,
the yields on the Offered Certificates will depend on the rate and timing of
Realized Losses, including Excess Losses. Excess Losses could occur at a time
when one or more Classes of Subordinate Certificates are still outstanding and
otherwise available to absorb other types of Realized Losses.
 
     The effective yields to the holders of the Offered Certificates will be
lower than the yields otherwise produced by the applicable rate at which
interest is passed through to such holders and the purchase price of such
Certificates because monthly distributions will not be payable to such holders
until the 20th day (or, if such day is not a business day, the following
business day) of the month following the month in which interest accrues on the
Mortgage Loans (without any additional distribution of interest or earnings
thereon in respect of such delay).
 
PREPAYMENT CONSIDERATIONS AND RISKS
 
     The rate of principal payments on the Offered Certificates, the aggregate
amount of each interest payment on the Offered Certificates and the yield to
maturity of Offered Certificates purchased at a price other than par are
directly related to the rate and timing of payments of principal on the Mortgage
Loans. The principal payments on the Mortgage Loans may be in the form of
scheduled principal payments or principal prepayments (for this purpose, the
term "principal prepayment" includes prepayments and any other recovery of
principal in advance of its Scheduled Due Date, including liquidations due to
default, casualty, condemnation and the like). Any such prepayments will result
in distributions to holders of the Offered Certificates of amounts which would
otherwise be distributed over the remaining term of the Mortgage Loans. See
"Maturity, Prepayment Considerations and Weighted Average Life of the
Certificates" in the Prospectus. The rate at which mortgage loans in general
prepay may be influenced by a number of factors, including general economic
conditions, mortgage market interest rates, availability of mortgage funds and
homeowner mobility. In general, if prevailing interest rates fall significantly
below the Mortgage Rates on the Mortgage Loans, the Mortgage Loans are likely to
prepay at higher rates than if prevailing rates remain at or above the interest
rates on the Mortgage Loans. Conversely, if interest rates rise above the
interest rates on the Mortgage Loans, the rate of prepayment would be expected
to decrease.
 
     The timing of changes in the rate of prepayments may significantly affect
the actual yield to investors, even if the average rate of principal prepayments
is consistent with the expectations of investors. In general, the earlier the
payment of principal of the Mortgage Loans the greater the effect on an
investor's yield to maturity. As a result, the effect on an investor's yield of
principal prepayments occurring at a rate higher (or lower) than the rate
anticipated by the investor during the period immediately following the issuance
of the Certificates will not be offset by a subsequent like reduction (or
increase) in the rate of principal prepayments.
 
     As described herein under "Description of the
Certificates -- Distributions", the Senior Prepayment Percentage of principal
prepayments (excluding for this purpose, liquidations due to default, casualty,
condemnation and the like, but including Balloon Payments) will be initially
distributed to the Classes of Senior Certificates (other than the Class A-4
Certificates) then entitled to receive principal distributions. This may result
in all (or a disproportionate percentage) of such principal prepayments
(including Balloon Payments) being distributed to holders of certain Classes of
Senior Certificates (other than the Class A-4
 
                                      S-40
<PAGE>   43
 
Certificates) and none (or less than their pro rata share) of such principal
prepayments being distributed to holders of the Class A-4 Certificates and the
Subordinate Certificates during the periods of time described in the definition
of "Senior Prepayment Percentage." Holders of the Class A-4 Certificates will
generally only receive principal prepayments (including Balloon Payments) if, as
and when the Subordinate Certificates are entitled to receive such principal
prepayments.
 
     Because the Class B-3, Class B-4 and Class R Certificates are not entitled
to principal distributions until the Offered Certificates are paid in full, the
Offered Certificates will receive a greater percentage of the principal payments
on the Mortgage Loans than would otherwise be the case if all Classes of
Certificate were entitled to a pro rata portion of such payments on each
Distribution Date. In addition, on each Distribution Date up to and including
the Accretion Termination Date, the Accretion Amount will be distributed as a
principal distribution to the Class or Classes of Offered Certificates entitled
thereto as set forth above in "Description of the
Certificates -- Distributions -- Accretion Amount." This feature will result in
the acceleration of some or all of the Classes of Offered Certificates relative
to the amortization of the Mortgage Loans. Both of these features will shorten
the weighted average lives of the Offered Certificates.
 
     Approximately 99% of the Mortgage Loans (by Cut-off Date Pool Principal
Balance) permit the Mortgagor to prepay the Mortgage Loans, in whole or in part,
at any time without penalty. The other Mortgage Loans contain prepayment
penalties. The rate of payment of principal may also be affected by any
repurchase of the Mortgage Loans permitted or required by the Pooling Agreement.
See "The Pooling and Servicing Agreement -- Assignment of Mortgage Loans" and
"The Pooling and Servicing Agreement -- Termination; Optional Termination"
herein.
 
     Some of the Mortgage Loans include due-on-sale clauses which allow the
holder of the Mortgage Loan to demand payment in full of the remaining principal
balance upon sale or certain transfers of the property securing such Mortgage
Loan. The Master Servicer may enforce "due-on-sale" clauses to the extent
permitted by applicable law. The Master Servicer may, however, waive its right
to enforce such "due-on-sale" clauses as described above under "Risk
Factors -- Yield and Prepayment Considerations." See "Maturity, Prepayment
Considerations and Weighted Average Life of Certificates" in the Prospectus.
Acceleration of Mortgage Loans as a result of enforcement of such "due-on-sale"
provisions in connection with transfers of the related Mortgaged Properties or
the occurrence of certain other events resulting in acceleration would affect
the level of prepayments on the Mortgage Loans, thereby affecting the weighted
average lives of the Classes of the Offered Certificates.
 
     As further described in "The Pooling and Servicing Agreement -- Optional
Purchase of Mortgage Loans", the Master Servicer has the option, but is not
obligated, to purchase from the Pool any Mortgage Loan 90 days or more
delinquent at the Purchase Price for such Mortgage Loan or to sell any such
Mortgage Loan in a commercially reasonable manner if the Master Servicer
determines that such a sale would produce a greater recovery on a present value
basis than would liquidation of the related Mortgaged Property. Furthermore, the
Master Servicer is permitted under the Pooling Agreement to solicit borrowers
under the Balloon Loans to refinance such Mortgage Loan; provided that any such
solicitation is made not earlier than one year before maturity of any such
Mortgage Loan and such Mortgage Loan is refinanced no earlier than six months
before its maturity. See "The Pooling and Servicing Agreement -- Termination;
Optional Termination" herein and "The Pooling and Servicing
Agreement -- Termination; Repurchase of Mortgage Loans and Mortgage
Certificates" in the Prospectus for a description of the Master Servicer's
option to repurchase the Mortgage Loans when the Pool Principal Balance is less
than 10% of the Cut-off Date Pool Principal Balance. The Sellers may be required
to repurchase Mortgage Loans because of defective documentation or breaches of
the representations and warranties with respect to the Mortgage Loans. Any such
repurchases or refinancings of Balloon Loans prior to maturity may shorten the
weighted average lives of the Classes of Offered Certificates.
 
     Investors should also note that under the circumstances described above
under "The Pooling and Servicing Agreement -- Modification of Mortgage Loans,"
the Master Servicer may modify the date on which any Balloon Payment is due by
up to six months. Any such modification may extend the weighted average lives of
the Classes of Offered Certificates.

ASSUMPTIONS RELATING TO TABLES
 
   
     The Decrement Tables have been prepared on the basis of the following
assumptions (the "Assumptions"): (i) the Mortgage Pool consists of 354
hypothetical mortgage loans having the characteristics set forth in Appendix B;
(ii) the initial Class Certificate Balances and Pass-Through Rates for the
Certificates are set forth on the cover page hereto and in "Summary of Terms"
herein; (iii) there are no Net Prepayment Interest Shortfalls, delinquencies or
Realized Losses on the Mortgage Loans; (iv) Scheduled Payments on the Mortgage
Loans are timely received on their respective Scheduled Due Dates in each month
commencing in June 1996 and prepayments representing prepayments in full of
individual Mortgage Loans are received on the last day of each month commencing
in May 1996, and are made at the indicated percentages of CPR set forth in the
related tables in this Prospectus Supplement and include 30 days' interest
thereon; (v) the Master Servicer does not exercise its right of optional
termination described herein; (vi) no Mortgage Loans are required to be
purchased from the Pool and no Mortgage Loans are substituted for other Mortgage
Loans as required by the Pooling Agreement; (vii) payments on the Offered
Certificates are received on the twentieth day of each month commencing in June
1996; (viii) the Offered Certificates will be issued on May 30, 1996; (ix) the
Offered Certificates are paid in accordance with the provisions under
"Description of the Certificates"; (x) the terms of all Balloon Loans are
extended by six months; and (xi) the Accretion Amount for each Distribution Date
is calculated as set forth above under "Description of the
Certificates -- Residual Certificates" herein. Although the characteristics of
the mortgage loans for the Decrement Tables have been prepared on the basis of
the characteristics of the Mortgage Loans which are expected to be in the Pool,
there is no assurance that the Assumptions will reflect the actual
characteristics or performance of the Mortgage Loans or that the performance of
the Offered Certificates will conform to the results set forth in the tables.
    
 
   
ADDITIONAL INFORMATION
    
 
   
     The Sponsor intends to file certain additional yield tables and other
computational materials with respect to one or more Classes of Offered
Certificates with the Commission in a Current Report on Form 8-K to be dated May
21, 1996. Such tables and materials were prepared by one or more of the
Underwriters at the request of certain prospective investors, based on
assumptions provided by, and satisfying the special requirements of, such
prospective investors. Such tables and assumptions may be based on assumptions
that differ from the Assumptions. Accordingly, such tables and other materials
may not be relevant to or appropriate for investors other than those
specifically requesting them.
    
 
WEIGHTED AVERAGE LIVES OF THE OFFERED CERTIFICATES
 
     Weighted average life refers to the average amount of time that will elapse
from the date of issuance of an Offered Certificate until each dollar in
reduction of the Class Certificate Balance thereof is distributed to the
investor. The weighted average lives of such Classes of Offered Certificates
will be influenced by, among other things, the rate at which principal of the
Mortgage Loans is paid, which may be in the form of scheduled amortization or
prepayments (for this purpose, the term "prepayments" includes prepayments and
liquidations due to default, casualty, condemnation and the like), the timing of
changes in such rate of payments and the priority sequence of distributions of
principal of such Offered Certificates. The interaction of the foregoing factors
may have different effects on each Class of Offered Certificates and the effects
on any such Class may vary at different times during the life of such Class.
Accordingly, no assurance can be given as to the weighted average life of any
such Class of Offered Certificates. For an example of how the weighted average
lives of the Offered Certificates are affected by the foregoing factors at
various constant percentages of CPR, see the Decrement Tables below.
 
     Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. The model used in this Prospectus Supplement is
the Constant Prepayment Rate ("CPR"), which represents an assumed annualized
rate of prepayment relative to the then outstanding principal balance on a pool
of new mortgage loans. As used in the tables, 5% indicates prepayments at an
annual rate of 5%; 10% indicates
 
                                      S-42
<PAGE>   45
 
prepayments at an annual rate of 10% and so on. CPR does not purport to be a
historical description of prepayment experience or a prediction of the
anticipated rate of prepayment of any pool of mortgage loans, including the
Mortgage Loans. The Sponsor believes that no existing statistics of which it is
aware provide a reliable basis for holders of Offered Certificates to predict
the amount or the timing of receipt of prepayments on the Mortgage Loans.
 
     The Decrement Tables set forth below have been prepared on the basis of the
Assumptions described above under "-- Assumptions Relating to Tables." There
will likely be discrepancies between the characteristics of the actual Mortgage
Loans included in the Pool and the characteristics of the Mortgage Loans assumed
in preparing the Decrement Tables. Any such discrepancy may have an effect upon
the percentages of initial Class Certificate Balances outstanding set forth in
the Decrement Tables (and the weighted average lives of the Offered
Certificates). In addition, to the extent that the Mortgage Loans that actually
are included in the Pool have characteristics that differ from those assumed in
preparing the following Decrement Tables, the Class Certificate Balance of any
such Class of Offered Certificates will be reduced to zero earlier or later than
indicated by such Decrement Tables.
 
     Furthermore, the information contained in the Decrement Tables with respect
to the weighted average life of any Offered Certificate is not necessarily
indicative of the weighted average life of such Class of Offered Certificate
that might be calculated or projected under different or varying prepayment
assumptions.
 
     It is not likely that (i) all of the Mortgage Loans will have the Mortgage
Rates or remaining terms to maturity assumed or (ii) the Mortgage Loans will
prepay at the indicated percentage of CPR until maturity. In addition, the
diverse remaining terms to maturity of the Mortgage Loans could produce slower
or faster distributions in reduction of Class Certificate Balances than
indicated in the Decrement Table at the various percentages of CPR specified.
 
     Based upon the foregoing assumptions, the following Decrement Tables
indicate the projected weighted average life of each Class of the Offered
Certificates and set forth the percentages of the initial Class Certificate
Balance of each such Class that would be outstanding after each of the dates
shown at various constant percentages of the CPR.

                               CREDIT ENHANCEMENT
 
SUBORDINATION OF CERTAIN CLASSES
 
     The rights of Subordinate Certificateholders to receive distributions with
respect to the Mortgage Loans will be subordinated to such rights of Senior
Certificateholders, and the rights of the holders of each Class of Subordinate
Certificates (other than the Class B-1 Certificates) to receive such
distributions will be further subordinated to such rights of the holders of the
Class or Classes of Subordinate Certificates with a higher priority of payment
as described herein under "Description of the Certificates -- Priority of
Distributions Among Classes of Certificates." The subordination of the
Subordinate Certificates to the Senior Certificates and the further
subordination within the Subordinate Certificates is intended to increase the
likelihood of receipt by the Senior Certificateholders (to the extent of the
subordination provided by the Subordinate Certificates) and each Class of
Subordinate Certificates (to the extent of the combined subordination provided
by the Class or Classes of Subordinate Certificates with a lower priority of
payment) of the maximum amount to which they are entitled on any Distribution
Date and, to provide such holders protection against Realized Losses other than
Excess Losses. In addition, the Subordinate Certificates will provide limited
protection against Special Hazard Losses, Bankruptcy Losses and Fraud Losses up
to the Special Hazard Loss Coverage Amount, Bankruptcy Loss Coverage Amount and
Fraud Loss Coverage Amount, respectively, as described below. Realized Losses
will be allocated to the Classes of Certificates in the manner described herein
under "Description of the Certificates -- Allocation of Losses."
 
     The Subordinate Certificates will provide protection to the Classes of
Certificates of higher relative priority against (i) Special Hazard Losses in an
initial amount expected to be up to approximately $1,228,652 (the "Special
Hazard Loss Coverage Amount"), (ii) Bankruptcy Losses in an initial amount
expected to be up to approximately $200,000 (the "Bankruptcy Loss Coverage
Amount") and (iii) Fraud Losses in an initial amount expected to be up to
approximately $3,685,955 (the "Fraud Loss Coverage Amount").
 
     The Special Hazard Loss Coverage Amount will be reduced, from time to time,
to be an amount equal on any Distribution Date to the lesser of (a) the greatest
of (i) 1% of the aggregate of the Scheduled Principal Balances of the Mortgage
Loans, (ii) twice the Scheduled Principal Balance of the largest Mortgage Loan
and (iii) the aggregate principal balances of the Mortgage Loans secured by
Mortgaged Properties located in the single California postal zip code area
having the highest aggregate principal balance of any such zip code area and (b)
the Special Hazard Loss Coverage Amount as of the Closing Date less the amount,
if any, of losses attributable to Special Hazard Mortgage Loans incurred since
the Closing Date. All Scheduled Principal Balances for the purpose of this
definition will be calculated as of the Scheduled Due Date in the month
preceding such Distribution Date.
 
     The Fraud Loss Coverage Amount will be reduced, from time to time, by the
amount of Fraud Losses allocated to the Certificates. In addition, on each
anniversary of the Cut-off Date, the Fraud Loss Coverage Amount will be reduced
as follows: (a) on the first anniversary of the Cut-off Date, to an amount equal
to the lesser of (i) 2% of the then current Pool Principal Balance and (ii) the
excess of the Fraud Loss Coverage Amount as of the Cut-off Date over the
cumulative amount of Fraud Losses allocated to the Certificates since the
Cut-off Date, (b) on the second, third and fourth anniversaries of the Cut-off
Date, to an amount equal to the lesser of (i) 1% of the then current Pool
Principal Balance and (ii) the excess of the Fraud Loss Coverage Amount as of
the preceding anniversary of the Cut-off Date over the cumulative amount of
Fraud Losses allocated to the Certificates since such preceding anniversary and
(b) on the fifth anniversary of the Cut-off Date, to zero.
 
     The Bankruptcy Loss Coverage Amount will be reduced, from time to time, by
the amount of Bankruptcy Losses allocated to the Certificates.
 
     The amount of coverage provided by the Subordinate Certificates for Special
Hazard Losses, Bankruptcy Losses and Fraud Losses may be cancelled or reduced
from time to time for each of the risks covered, provided that the then current
ratings of the Certificates assigned by the Rating Agencies are not adversely
affected thereby. In addition, a reserve fund or other form of credit
enhancement may be substituted for the
 
                                      S-50
<PAGE>   53
 
protection provided by the Subordinate Certificates for Special Hazard Losses,
Bankruptcy Losses and Fraud Losses.
 
     As used herein, a "Deficient Valuation" is a bankruptcy proceeding whereby
the bankruptcy court may establish the value of the Mortgaged Property at an
amount less than the then outstanding principal balance of the Mortgage Loan
secured by such Mortgaged Property or may reduce the outstanding principal
balance of a Mortgage Loan. In the case of a reduction in the value of the
related Mortgaged Property, the amount of the secured debt could be reduced to
such value, and the holder of such Mortgage Loan thus would become an unsecured
creditor to the extent the outstanding principal balance of such Mortgage Loan
exceeds the value so assigned to the Mortgaged Property by the bankruptcy court.
In addition, certain other modifications of the terms of a Mortgage Loan can
result from a bankruptcy proceeding, including the reduction (a "Debt Service
Reduction") of the amount of the monthly payment on the related Mortgage Loan.
Notwithstanding the foregoing, no such occurrence shall be considered a Debt
Service Reduction or Deficient Valuation so long as the Master Servicer is
pursuing any other remedies that may be available with respect to the related
Mortgage Loan and (i) such Mortgage Loan is not in default with respect to
payment due thereunder or (ii) scheduled monthly payments of principal and
interest are being advanced by the Master Servicer without giving effect to any
Debt Service Reduction.
 
                                USE OF PROCEEDS
 
     The Sponsor will apply the net proceeds of the sale of the Offered
Certificates against the purchase price of the Mortgage Loans.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     An election will be made to treat the Pool as a "real estate mortgage
investment conduit" ("REMIC") for federal income tax purposes. The Regular
Certificates will constitute "regular interests" in the REMIC and will be
treated as debt instruments of the Pool for federal income tax purposes with
payment terms equivalent to the terms of such Certificates. The Residual
Certificates will constitute the sole class of "residual interest" in the REMIC
(the "Residual Certificate").
 
     Offered Certificates.  The Offered Certificates generally will be treated
as debt instruments issued by the REMIC for federal income tax purposes. Income
on the Offered Certificates must be reported under an accrual method of
accounting.
 
   
     Certain Classes of the Offered Certificates may, depending on their
respective issue prices, be treated for federal income tax purposes as having
been issued with an amount of original issue discount equal to the difference
between their principal balance and their issue price. See "Certain Federal
Income Tax Consequences" in the Prospectus. For purposes of determining the
amount and rate of accrual of OID and market discount, the Trust intends to
assume that there will be prepayments on the Mortgage Loans at a rate equal to
10% CPR (the "Prepayment Assumption"). No representation is made as to whether
the Mortgage Loans will prepay at the foregoing rate or any other rate.
Computing accruals of OID in the manner described in the Prospectus may
(depending on the actual rate of prepayments during the accrual period) result
in the accrual of negative amounts of OID on the Certificates issued with OID in
an accrual period. Holders will be entitled to offset negative accruals of OID
only against future OID accrual on such Certificates.
    
 
     Effect of Losses and Delinquencies.  As described above, the Class B
Certificates are subordinated to the Senior Certificates. In the event there are
losses or delinquencies on the Mortgage Loans, amounts that otherwise would be
distributed on the Class B Certificates may instead be distributed on the Senior
Certificates. Holders of the Class B Certificates nevertheless will be required
to report interest with respect to such Class B Certificates under an accrual
method without giving effect to delays and reductions in distributions on such
Certificates attributable to losses and delinquencies on the Mortgage Loans in
the Pool, except to the extent it can be established, for tax purposes, that
such amounts are uncollectible. As a result, the amount of income reported by
holders of the Class B Certificates in any period could significantly exceed the
amount of cash distributed to such holders in that period. The holders of Class
B Certificates will eventually be allowed a loss (or will be allowed to report a
lesser amount of income) to the extent that the
 
                                      S-51
<PAGE>   54
 
aggregate amount of distributions on such Certificates is reduced as a result of
losses and delinquencies on the Mortgage Loans in the Pool. However, the timing
and character of such losses or reductions in income are uncertain. Although not
entirely clear, it appears that holders of the Class B Certificates that are
corporations should in general be allowed to deduct as an ordinary loss any loss
sustained during the taxable year on account of any such Certificates becoming
wholly or partially worthless, and that, in general, holders of Certificates
that are not corporations should be allowed to deduct as short-term capital loss
any loss sustained during the taxable year on account of any such Certificates
becoming wholly worthless. Although the matter is unclear, non-corporate holders
of Certificates may be allowed a bad debt deduction at such time that the
principal balance of any such Certificate is reduced to reflect realized losses
resulting from any liquidated Mortgage Loans. The Internal Revenue Service,
however, could take the position that non-corporate holders will be allowed a
bad debt deduction to reflect realized losses only after all Mortgage Loans
remaining in the Pool have been liquidated or the Mortgage Loans have been
otherwise retired. Potential investors and Holders of the Certificates are urged
to consult their own tax advisors regarding the appropriate timing, amount and
character of any loss sustained with respect to such Certificates, including any
loss resulting from the failure to recover previously accrued interest or
discount income. Special loss rules are applicable to banks and thrift
institutions, including rules regarding reserves for bad debts. Such taxpayers
are advised to consult their tax advisors regarding the treatment of losses on
Certificates.
 
     The Offered Certificates will be treated as regular interests in a REMIC
under section 860G of the Code. Accordingly, the Offered Certificates will be
treated as (i) qualifying real property loans within the meaning of section
593(d)(1) of the Code, (ii) assets described in section 7701(a)(19)(C) of the
Code, and (iii) "real estate assets" within the meaning of section 856(c)(5) of
the Code, in each case to the extent described in the Prospectus. Interest on
the Offered Certificates will be treated as interest on obligations secured by
mortgages on real property within the meaning of section 856(c)(3)(B) of the
Code to the same extent that the Offered Certificates are treated as real estate
assets. See "Certain Federal Income Tax Consequences" in the Prospectus.
 
                              ERISA CONSIDERATIONS
 
     A fiduciary of any employee benefit plan subject to the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), or the Code, should carefully
review with its legal advisors whether the purchase or holding of an Offered
Certificate could give rise to a transaction prohibited or not otherwise
permissible under ERISA or the Code. No Class B-1 or Class B-2 Certificate may
be transferred unless the transferor delivers to the Trustee (i) a certificate
satisfactory to the Trustee to the effect that such transferee neither is nor is
acting on behalf of a plan subject to ERISA or, if the transferor is an
insurance company that it is purchasing such Certificates with funds from its
general account and that such transfer is covered by PTCE 95-60; or (ii) an
opinion of counsel satisfactory to the Trustee to the effect that such transfer
will not result in the assets of the Pool being "plan assets." See "ERISA
Considerations" in the Prospectus.
 
     The U.S. Department of Labor has granted to NationsBanc Capital Markets,
Inc., an administrative exemption (Prohibited Transaction Exemption 93-31;
Exemption Application No. D-9105) (the "Exemption") from certain of the
prohibited transaction rules of ERISA and the related excise tax provisions of
Section 4975 of the Code with respect to the initial purchase, the holding and
the subsequent resale by Plans of certificates in pass-through trusts that
consist of certain receivables, loans and other obligations that meet the
conditions and requirements of the Exemption. The Exemption applies to mortgage
loans such as the Mortgage Loans in the Pool.
 
     For a general description of the Exemption and the conditions that must be
satisfied for the Exemption to apply, see "ERISA Considerations" in the
Prospectus.
 
     The Underwriters believe that the Exemption will apply to the acquisition
and holding of the Offered Certificates, other than the Class B-1 and Class B-2
Certificates, by Plans and that all conditions of the Exemption other than those
within the control of the investors will be met. In addition, as of the date
hereof, there is no single Mortgagor that is the obligor on 5% of the Mortgage
Loans included in the Pool by aggregate unamortized principal balance of the
assets of the Pool.
 
                                      S-52
<PAGE>   55
     Prospective Plan investors should consult with their legal advisors
concerning the impact of ERISA and the Code, the applicability of PTCE 83-1
described in the Prospectus and the Exemption, and the potential consequences in
their specific circumstances, prior to making an investment in the Offered
Certificates. Moreover, each Plan fiduciary should determine whether under the
general fiduciary standards of investment prudence and diversification, an
investment in the Offered Certificates is appropriate for the Plan, taking into
account the overall investment policy of the Plan and the composition of the
Plan's investment portfolio.
 
                             METHOD OF DISTRIBUTION
 
   
     Subject to the terms and conditions set forth in the Underwriting

     Distribution of the Offered Certificates will be made by the Underwriters
from time to time in negotiated transactions or otherwise at varying prices to
be determined at the time of sale. Proceeds to the Sponsor from the sale of the
Offered Certificates will be 99.125% of the aggregate principal balance of the
Mortgage Loans, plus accrued interest at the weighted average of the
Pass-Through Rates from the Cut-off Date to the date of issuance of the Offered
Certificates but before deducting expenses payable by the Sponsor. In connection
with the purchase and sale of the Offered Certificates, the Underwriters may be
deemed to have received compensation from the Sponsor in the form of
underwriting discounts.
    
 
     The Sponsor has been advised by the Underwriters that they intend to make a
market in the Offered Certificates but have no obligation to do so. There can be
no assurance that a secondary market for the Offered Certificates will develop
or, if it does develop, that it will continue.
 
     The Sponsor has agreed to indemnify the Underwriters against, or make
contributions to the Underwriters with respect to, certain liabilities,
including liabilities under the Securities Act of 1933, as amended.
 
     NationsBanc Capital Markets, Inc. ("NCMI"), one of the Underwriters, is an
affiliate of the Sponsor and is a registered broker/dealer. Any obligations of
NCMI are the sole responsibility of NCMI and do not create any obligation or
guarantee on the part of any affiliate of NCMI.
 
                                 LEGAL MATTERS
 
     Certain legal matters will be passed upon for the Sponsor by Robert W.

                              CERTIFICATE RATINGS
 
     It is a condition to the issuance of the Offered Certificates that the
Offered Certificates be rated by Moody's and Duff & Phelps at least as follows:

     Ratings on mortgage pass-through certificates address the likelihood of
receipt by Certificateholders of payments required under the Pooling Agreement.
 
     Moody's ratings take into consideration the credit quality of the Pool
including any credit support providers, structural and legal aspects associated
with the Offered Certificates, and the extent to which the payment stream of the
Mortgage Pool is adequate to make payments required under the Offered
Certificates. Moody's ratings on the Offered Certificates, do not, however,
constitute a statement regarding frequency of prepayments on the Mortgage Loans.
As a result, holders of the Offered Certificates might suffer a lower than
anticipated yield.
 
     The ratings assigned by Duff & Phelps to mortgage pass-through certificates
address the likelihood of the receipt by certificateholders of all distributions
to which they are entitled under the transaction structure. Duff & Phelps'
ratings reflect its analysis of the riskiness of the Mortgage Loans and its
analysis of the structure of the transaction as set forth in the operative
documents. Duff & Phelps' ratings do not address the effect on the certificates'
yield attributable to prepayments or recoveries on the Mortgage Loans.
 
     The Sponsor has not requested a rating of any Class of Offered Certificates
by any rating agency other than Moody's and Duff & Phelps. However, there can be
no assurance as to whether any other rating agency will rate the Offered
Certificates, or if it does, what rating would be assigned by such other rating
agency. The rating assigned by any such other rating agency to a Class of
Offered Certificates may be lower than the ratings assigned by Moody's and Duff
& Phelps.
 
     The rating of the Offered Certificates should be evaluated independently
from similar ratings on other types of securities. 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.

                               Certificate Balance has been fully amortized,

                               that are not monthly may receive Special
                               Distributions of principal on any Special
                               Distribution Date specified in the related
                               Supplement. See "Description of
                               Certificates -- Special Distributions" herein.
 
  C. Credit Support........  The assets in a Pool or the Certificates of one or
                               more classes in the related Series may have the
                               benefit of one or more types of credit support as
                               described in the related Supplement. The
                               protection against losses afforded by any such
                               credit support may be limited. The type of credit
                               support will be determined based on the
                               characteristics of the Mortgage Assets in the
                               related Pool and other factors. See "Credit
                               Support" herein.
 
     1. Subordination......  A Series of Certificates may consist of one or more
                               classes of Senior Certificates and one or more
                               classes of Subordinate Certificates. If so
                               specified in the related Supplement, certain
                               classes of Subordinate Certificates may be senior
                               to other Classes of Subordinate Certificates and
                               be rated investment grade ("Mezzanine
                               Certificates"). The rights of holders of the
                               Subordinate Certificates of a Series
                               ("Subordinate Certificateholders") to receive
                               distributions with respect to the assets in the
                               related Pool will be subordinated to such rights
                               of holders of the Senior Certificates of the same
                               Series ("Senior Certificateholders") to the
                               extent described in the related Supplement. This
                               subordination is intended to enhance the
                               likelihood of regular receipt by Senior
                               Certificateholders of the full amount of their
                               scheduled monthly payments of principal and
                               interest. The protection afforded to Senior
                               Certificateholders of a Series by means of the
                               subordination feature will be accomplished by (i)
                               the preferential right of such holders to
                               receive, prior to any distribution being made in
                               respect of the related Subordinate Certificates,
                               the amounts of principal and interest due them on
                               each Distribution Date out of the funds available
                               for distribution on such date and, to the extent
                               described in the related Supplement, by the right
                               of such holders to receive future distributions
                               on the assets in the related Pool that would
                               otherwise have been payable to Subordinate
                               Certificateholders; (ii) reducing the ownership
                               interest of the related Subordinate Certificates;
                               (iii) a combination of clauses (i) and (ii)
                               above; or (iv) as otherwise described in the
                               related Supplement. If so specified in the
                               related Supplement, subordination may apply only
                               in the event of certain types of losses not
                               covered by other forms of credit support, such as
                               hazard losses not covered by standard hazard
                               insurance policies or losses due to the
                               bankruptcy or fraud of the mortgagor. The related
                               Supplement will set forth information concerning,
                               among other things, the amount of subordination
                               of a class

<PAGE>   74
 
                               or classes of Subordinate Certificates in a
                               Series, the circumstances in which such
                               subordination will be applicable and the manner,
                               if any, in which the amount of subordination will
                               decrease over time.
 
     2. Reserve Fund.......  One or more reserve funds (the "Reserve Fund") may
                               be established and maintained for each Series.
                               The related Supplement will specify whether or
                               not any such Reserve Fund will be included in the
                               corpus of the Pool for such Series and will also
                               specify the manner of funding the related Reserve

                               combination thereof. Any GNMA Certificates
                               included in a Pool will be guaranteed as to full
                               and timely payment of principal and interest by
                               GNMA, which guaranty is backed by the full faith
                               and credit of the United States. Any FHLMC
                               Certificates included in the Pool will be
                               guaranteed as to the timely payment of interest
                               and ultimate collection (and, if so specified in
                               the related Supplement, timely payment) of
                               principal by FHLMC. Any FNMA Certificates
                               included in a Pool will be guaranteed as to
                               timely payment of scheduled payments of principal
                               and interest by FNMA. No FNMA or FHLMC
                               Certificates will be backed, directly or
                               indirectly, by the full faith and credit of the
                               United States. No Private Certificates will be
                               backed, directly or indirectly, by any agency or
                               instrumentality of the United States but may have
                               other forms of credit support, as described in
                               the related Supplement.
 
                             Each Mortgage Certificate will evidence an interest
                               in a pool of mortgage loans and/or cooperative
                               loans, and/or in principal distributions and
                               interest distributions thereon. The Supplement
                               for each Series will specify the aggregate
                               approximate principal balance of GNMA, FNMA and
                               FHLMC Certificates and of Private Certificates
                               included in a Pool and will describe the
                               principal characteristics of the underlying
                               mortgage loans or cooperative loans and any
                               insurance, guaranty or other credit support
                               applicable to such underlying loans, the Mortgage
                               Certificates or both. In addition, the related
                               Supplement will describe the terms upon which
                               distributions will be made to the Trustee as the
                               holder of the Mortgage Certificates. The Mortgage
                               Certificates included in any Pool will be
                               registered in the name of the Trustee or its
                               nominee or in the case of book-entry Mortgage
                               Certificates in the name of a financial
                               intermediary with a Federal Reserve Bank or a
                               clearing corporation and will be held by the
                               Trustee only for the benefit of holders of the
                               related Series of Certificates.
 
                             The GNMA, FNMA and FHLMC Certificates are
                               collectively referred to herein as the "Agency
                               Certificates."
 
  C. Certificate Account...  All distributions on any Mortgage Certificates and
                               all payments (including prepayments, liquidation

                               the Servicer on any Mortgage Loans included in
                               the Pool for a Series will be remitted to an
                               account (the "Certificate Account"), and,
                               together with any amounts available pursuant to
                               the terms of any applicable credit support and
                               any other amounts described in the related
                               Supplement, will be available for distribution on
                               the Certificates of such Series as described in
                               the related Supplement. Such Certificate Account
                               shall be an Eligible Account or Accounts
                               established and maintained by the Servicer for
                               the benefit of holders of a Series of
                               Certificates.
 
Optional Termination.......  The Servicer or, if specified in the related
                               Supplement for a Series of REMIC Certificates,
                               holders of the Residual Certificates of such
                               Series or the REMIC may have the option to
                               repurchase the Mortgage Assets included in the
                               related Pool and thereby terminate the related
                               Pooling Agreement. Any such option will be
                               exercisable at the
 
                                        9

                               times and upon satisfaction of the conditions
                               specified in the related Supplement.
 
Tax Status of REMIC
  Certificates.............  Regular Certificates of a particular Series will be
                               treated as "regular interests" in the REMIC and
                               will be treated as debt instruments for federal
                               income tax purposes, and the Residual
                               Certificates of such Series will be treated as
                               "residual interests" in the REMIC. Holders of
                               Residual Certificates generally will include
                               their pro rata shares of the net income or loss
                               of the REMIC in determining their federal taxable
                               income.
 
                             Holders of Accrual Certificates and any other
                               classes of Regular Certificates issued with
                               original issue discount generally will be
                               required to include the original issue discount
                               (which for federal income tax purposes includes
                               interest accrued on Accrual Certificates as well
                               as current interest paid thereon) in gross income
                               over the life of the Regular Certificates.
 
                             Distributions on Regular Certificates to foreign
                               investors generally will not be subject to U.S.
                               withholding tax, provided applicable
                               certification procedures are complied with.
 
                             Subject to certain limitations that may be
                               applicable to Buydown Loans, REMIC Certificates
                               will be treated as "qualifying real property
                               loans" for mutual savings banks and domestic
                               building and loan associations, "regular or
                               residual interests in a REMIC" for domestic
                               building and loan associations and "real estate
                               assets" for real estate investment trusts. See
                               "Certain Federal Income Tax Consequences -- REMIC
                               Certificates" herein.
 
Tax Status of Non-REMIC
  Certificates.............  For federal income tax purposes, the trust created
                               to hold the Mortgage Assets for each Series of
                               Non-REMIC Certificates will be classified as a
                               grantor trust and not as an association taxable
                               as a corporation. Holders of Non-REMIC
                               Certificates of such Series which are not IO
                               Certificates will be treated as owners of
                               undivided interests in the trust and as equitable
                               owners of undivided interests in each of the
                               Mortgage Assets held by the trust, and such
                               holders will be taxed on their pro rata shares of
                               the income from the related Mortgage Assets and
                               may be allowed to deduct their pro rata shares of
                               reasonable servicing fees, consistent with their
                               methods of accounting, subject to limitation in
                               the case of Non-REMIC Certificates held by
                               individuals, estates, or trusts (either directly
                               or indirectly through certain pass-through
                               entities). If a Series of Non-REMIC Certificates
                               includes IO Certificates, holders of the
                               Certificates of such Series will be subject to
                               the "Stripped Bond Rules" of Section 1286 of the
                               Code.
 
                             Subject to certain limitations that may be
                               applicable to Buydown Loans, to the extent the
                               Mortgage Assets and the related interests qualify
                               for such treatment, interests in the Mortgage
                               Assets held by holders of applicable Non-REMIC
                               Certificates which are not IO Certificates will
                               be considered to represent "qualifying real
                               property loans" for mutual savings banks and
                               domestic building and loan associations and
                               "loans . . . secured by an interest in real
                               property" for domestic build-
 
                                       10
<PAGE>   79
 
                               ing and loan associations and "real estate
                               assets" for real estate investment trusts.
 
                             It is not clear whether IO Certificates will be
                               treated as representing an ownership interest in
                               qualifying assets and income under Sections
                               593(d), 7701(a)(19)(C)(v), 856(c)(5)(A) and
                               856(c)(3)(B) of the Code, although the policy
                               considerations underlying those Sections suggest
                               that such treatment should be available. It is
                               also not clear whether a reasonable prepayment
                               assumption should be applied in accruing original
                               issue discount on the IO Certificates.
 
                             See "Certain Federal Income Tax
                               Consequences -- Non-REMIC Certificates" herein.
 
Legal Investment...........  The Supplement for each Series of Certificates will
                               specify which, if any, of the classes of
                               Certificates offered thereby will constitute
                               "mortgage-related securities" for purposes of the
                               Secondary Mortgage Market Enhancement Act of 1984
                               ("SMMEA"). Classes of Certificates that qualify
                               as "Mortgage Related Securities" will be legal
                               investments for certain types of institutional
                               investors to the extent provided in SMMEA.
                               However, institutions whose investment activities
                               are subject to other legal investment laws and
                               regulations or review by certain regulatory
                               authorities may be subject to restrictions on
                               investment in certain classes of Certificates.
                               See "Legal Investment" herein.
 
ERISA Considerations.......  A fiduciary of any employee benefit plan or other
                               retirement plan or arrangement subject to the
                               Employee Retirement Income Security Act of 1974,
                               as amended ("ERISA") or the Code should carefully
                               review with its legal advisors whether the
                               purchase or holding of Certificates could give
                               rise to a transaction prohibited or not otherwise
                               permissible under ERISA or the Code. See "ERISA
                               Considerations" herein. Certain classes of
                               Certificates may not be transferred unless the
                               Trustee and the Sponsor are furnished with a
                               letter of representation or an opinion of counsel
                               to the effect that such transfer will not result
                               in violation of the prohibited transaction
                               provisions of ERISA and the Code and will not
                               subject the Trustee, the Sponsor or the Servicer
                               to additional obligations. Additionally, unless
                               otherwise specified in the related Supplement,
                               Certificates representing an interest in a Pool
                               consisting of Private Certificates may not be
                               transferred to an employee benefit plan or other
                               retirement plan or arrangement subject to ERISA.

Rating.....................  The Certificates of each class offered hereby and
                               by a Supplement will be rated in one of the four
                               highest rating categories by one or more
                               nationally recognized statistical rating

     Each Pool will consist of Mortgage Assets, any real estate acquired through
foreclosure or similar proceeding, any applicable credit support, the assets in
the Certificate Account, any minimum prepayment, reinvestment or similar
agreement and any other assets described in the related Supplement, all as
described herein and therein.
 
THE MORTGAGE LOANS
 
     The Mortgage Loans may be fixed- or adjustable-rate mortgage loans, or
participations or other beneficial interests in such mortgage loans, evidenced
by loan agreements, promissory notes or other evidence of indebtedness (the
"Mortgage Notes") secured primarily by first liens on one- to four-family
residential properties in any one of the fifty states, the District of Columbia,
Guam, Puerto Rico or any other territory of the United States. If so specified
in the related Supplement, the Mortgage Loans may include cooperative apartment
loans ("Cooperative Loans") secured by security interests in shares issued by
private, non-profit cooperative housing corporations and in the related
proprietary leases or occupancy agreements granting exclusive rights to occupy
specific dwelling units in such buildings. A "Mortgage" is a mortgage, deed of
trust or similar instrument with respect to a Mortgaged Property. The "Mortgaged
Properties" securing the Mortgage Notes will be comprised of one- to four-family
dwelling units that are either detached or semi-detached townhouses, rowhouses,
individual condominium units, individual units in planned unit developments and
certain other dwelling units. The Mortgaged Properties may include leasehold
interests in residential properties, the title to which is held by third party
lessors. The Mortgaged Properties may include vacation and second homes and
investment properties. Each Mortgage Loan will be selected by the Sponsor for
inclusion in a Pool from among those purchased, either directly or through
affiliates. Originators, servicers or sellers may be affiliated with the
Sponsor. All transactions involving affiliates will be conducted in a
commercially reasonable manner at arm's length.
 
     A Pool may include one or more of the following types of Mortgage Loans:
 
          (1) Fixed-rate, conventional Mortgage Loans providing for full
     amortization of principal in level monthly payments;
 
          (2) Conventional adjustable-rate mortgage loans ("ARMs"), as described
     under "ARMs" herein;
 
          (3) Fully amortizing graduated-payment Mortgage Loans ("GPMs"), which
     provide for lower periodic payments, or for payments of interest only,
     during the early years of the term, followed by periodic payments of
     principal and interest that increase periodically at a predetermined rate
     until the Mortgage Loan is repaid or for a specified number of years, after
     which level periodic payments begin; and
 
          (4) Any other type of Mortgage Loan, as described in the related
     Supplement.
 
     A Pool may contain certain Mortgage Loans ("Buydown Loans"), which include
provisions whereby the Seller or a third party partially subsidizes the monthly
payments of the Mortgagor during the early years of the Mortgage Loan, the
difference to be made up from a fund (a "Buydown Fund") contributed by the
Seller or third party at the time of origination of the Mortgage Loan. A Buydown
Fund will be in an amount equal either to the discounted value or full aggregate
amount of future payment subsidies. The underlying assumption of buydown plans
is that the income of the Mortgagor will increase during the buydown period as a
result of normal increases in compensation and of inflation, so that the
Mortgagor will be able to meet the full mortgage payments at the end of the
buydown period. To the extent that this assumption as to increased income is not
fulfilled, the possibility of defaults on Buydown Loans is increased. The
related Supplement will

* Whenever in this Prospectus the terms "Pool", "Certificates", "REMIC
  Certificates" and "Non-REMIC Certificates" are used, those terms apply, unless
  the context indicates otherwise, to one specific Pool, and the Certificates
  representing undivided interests therein. Similarly, the term "Certificate
  Rate" will refer to the Certificate Rate borne by a particular class of
  Certificates of a Series.
 
                                       12
<PAGE>   81
 
contain information with respect to any Buydown Loan concerning limitations on
the interest rate paid by the Mortgagor initially, on annual increases in the
interest rate and on the length of the buydown period.
 
     A Pool may contain certain Mortgage Loans evidenced by Contracts ("Land
Sale Contracts") for the sale of Mortgaged Properties pursuant to which the
mortgagor promises to pay the amount due thereon to the holder thereof with fee
title to the related Mortgaged Property held by such holder until the mortgagor
has made all of the payments required pursuant to such Land Sale Contract, at
which time fee title is conveyed to the mortgagor.
 
     Mortgage Loans with certain LTVs and/or certain principal balances may be
covered wholly or partially by Primary Mortgage Insurance Policies. The
existence, extent and duration of any such coverage will be described in the
related Supplement. The loan-to-value ratio ("LTV") of a Mortgage Loan at any
given time is the ratio, expressed as a percentage, of the then-outstanding
principal balance of the Mortgage Loan to the Appraised Value of the related
Mortgaged Property. Unless otherwise specified in the related Supplement, the
"Appraised Value" is either (x) the lesser of (a) the appraised value determined
in an appraisal obtained by the originator at origination of such Mortgage Loan
and (b) the sales price for such property, except that, in the case of Mortgage
Loans the proceeds of which were used to refinance an existing mortgage loan,
the Appraised Value of the related Mortgaged Property is the appraised value
thereof determined in an appraisal obtained at the time of refinancing or (y)
the appraised value determined in an appraisal made at the request of a
Mortgagor subsequent to origination in order to eliminate the Mortgagor's
obligation to keep a Primary Mortgage Insurance Policy in force.
 
     Each Supplement for a Series representing interests in a Pool that consists
of Mortgage Loans will contain information, as of the Cut-off Date and to the
extent known to the Sponsor, with respect to the Mortgage Loans contained in
such Pool, including: (i) the number of Mortgage Loans, (ii) the geographic
distribution of the Mortgage Loans; (iii) the aggregate principal balance of the
Mortgage Loans; (iv) the types of dwelling constituting the Mortgaged
Properties; (v) the longest and shortest scheduled term to maturity; (vi) the
maximum principal balance of the Mortgage Loans; (vii) the maximum LTV of the
Mortgage Loans at origination or such other date specified in the related
Supplement; (viii) the maximum and minimum Mortgage Rates; and (ix) the
aggregate principal balance of non-owner-occupied Mortgaged Properties.
 
     No assurance can be given that values of the Mortgaged Properties have
remained or will remain at their levels on the dates of origination of the
related Mortgage Loans. If the residential real estate market should experience
an overall decline in property values such that the outstanding principal
balances of the Mortgage Loans, and any secondary financing on the Mortgaged
Properties, in a particular 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. 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 actual rates of delinquencies, foreclosures and losses with
respect to any Pool. If losses on defaulted Mortgage Loans exceed the coverage
of any Primary Mortgage Insurance Policy or the amount of any credit support
arrangement described in the related Supplement, such losses will be borne by
holders of Certificates ("Certificateholders").
 
     ARMs.  Each ARM included in a Pool will be a conventional Mortgage Loan
which will bear interest at a Mortgage Rate that is adjusted periodically to be
equal (subject to rounding) to the index (the "Index") plus the specified
percentage (the "Mortgage Margin") added to the applicable Index in order to
compute the Mortgage Rate for such ARM, subject to certain limitations on the
amount of any single increase or decrease in the Mortgage Rate or on the maximum
Mortgage Rate for such ARM. If specified in the related Supplement, ARMs
included in a Pool may permit the Mortgagor to convert the Mortgage Rate to a
fixed rate, in the manner set forth in the related Supplement. Certain ARMs may
provide for periodic adjustments of scheduled payments in order to fully
amortize the Mortgage Loan by its stated maturity, while other ARMs may permit
the maturity to be extended or shortened in accordance with the portion of each
payment that is applied to interest in accordance with the periodic interest
rate adjustments.
 
                                       13
<PAGE>   82
 
     If an ARM provides for limitations on the amount by which monthly payments
may be increased or changes to the Mortgage Rate of the ARM are made more
frequently than payment changes, it is possible that an increase in the rate of
interest would not be covered by the amount of the scheduled payment. In that
case, the amount of the difference between the scheduled monthly payment and the
monthly interest accrued at the Mortgage Rate is added to the unpaid principal
balance of the Mortgage Loan and interest accrues on such added principal at the
then-applicable Mortgage Rate from the date of such addition. Such an adjustment
is referred to as "negative amortization". Negative amortization tends to
lengthen the weighted average life of the Mortgage Loans and may cause payments
near the maturity of the Mortgage Loan to be larger than the previously
scheduled monthly payments unless the terms of the Mortgage Loan permit its
maturity to be extended. If a Pool includes Mortgage Loans that provide for
negative amortization, the related Supplement will describe certain of the
effects on Certificateholders.
 
     At the Cut-off Date for a Pool that includes ARMs, the Pool may contain
ARMs which are newly originated and ARMs as to which one or more adjustments
have occurred. ARMs that have not had their first rate adjustment will generally
bear interest at rates that are lower than the rate that would otherwise be
produced by the sum of the applicable Index and the Mortgage Margin.
 
MORTGAGE CERTIFICATES
 
     All of the Mortgage Certificates will be registered in the name of the
Trustee or its nominee or, in the case of Mortgage Certificates issued only in
book-entry form, a financial intermediary (which may be the Trustee) that is a
member of the Federal Reserve System or of a clearing corporation on the books
of which the security is held. Each Mortgage Certificate will evidence an
interest in a pool of mortgage loans and/or cooperative loans and/or in
principal distributions and interest distributions thereon.
 
     The descriptions of GNMA, FHLMC and FNMA Certificates and of Private
Certificates that are set forth below are descriptions of certificates
representing proportionate interests in a pool of mortgage loans and in the
payments of principal and interest thereon. GNMA, FHLMC, FNMA or the issuer of a
particular series of Private Certificates may also issue mortgage-backed
securities representing a right to receive distributions of interest only or
principal only or disproportionate distributions of principal or interest or to
receive distributions of principal and/or interest prior or subsequent to
distributions on other certificates representing interests in the same pool of
mortgage loans. In addition, any of such issuers may issue certificates
representing interests in mortgage loans having characteristics that are
different from the types of mortgage loans described below. The terms of any
such certificates to be included in a Pool (and of the underlying mortgage
loans) will be described in the related Supplement, and the descriptions that
follow are subject to modification as appropriate to reflect the terms of any
such certificates that are actually included in a Pool.
 
     GNMA.  GNMA is a wholly owned corporate instrumentality of the United
States within the Department of Housing and Urban Development ("HUD"). Section
306(g) of Title III of the National Housing Act of 1934, as amended (the
"Housing Act"), authorizes GNMA to guarantee the timely payment of the principal
of and interest on certificates that are based on and backed by a pool of loans
("FHA Loans") insured or guaranteed by the United States Federal Housing
Administration (the "FHA") under the Housing Act or Title V of the Housing Act
of 1949, or by the United States Department of Veteran Affairs (the "VA") under
the Servicemen's Readjustment Act of 1944, as amended, or Chapter 37 of Title
38, United States Code or by pools of other eligible mortgage loans.
 
     Section 306(g) of the Housing Act provides that "the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guaranty under this subsection". To meet its
obligations under its guaranties, GNMA is authorized, under Section 306(d) of
the Housing Act, to borrow from the United States Treasury with no limitations
as to amount.
 
     GNMA Certificates.  All of the GNMA Certificates (the "GNMA Certificates")
will be mortgage-backed certificates issued and serviced by GNMA- or
FNMA-approved mortgage servicers. The mortgage loans underlying GNMA
Certificates may consist of FHA Loans secured by mortgages on one- to
four-family residential properties or multifamily residential properties, loans
secured by mortgages on one- to four-family
 
                                       14
<PAGE>   83
 
residential properties or multifamily residential properties, mortgage loans
which are partially guaranteed by the VA and other mortgage loans eligible for
inclusion in mortgage pools underlying GNMA Certificates. Unless otherwise
specified in the related Supplement, at least 90 percent by original principal
amount of the mortgage loans underlying a GNMA Certificate will be mortgage
loans having maturities of 20 years or more.
 
     Each GNMA Certificate provides for the payment by or on behalf of the
issuer of the GNMA Certificate to the registered holder of such GNMA Certificate
of monthly payments of principal and interest equal to the registered holder's
proportionate interest in the aggregate amount of the monthly scheduled
principal and interest payments on each underlying eligible mortgage loan, less
servicing and guaranty fees aggregating the excess of the interest on each such
mortgage loan over the GNMA Certificate pass-through rate. In addition, each
payment to a GNMA Certificateholder will include proportionate pass-through
payments to such holder of any prepayments of principal of the mortgage loan
underlying the GNMA Certificate, and the holder's proportionate interest in the
remaining principal balance in the event of a foreclosure or other disposition
of any such mortgage loan.
 
     The GNMA Certificates included in a Pool may be issued under either or both
of the GNMA I program ("GNMA I Certificates") and the GNMA II program ("GNMA II
Certificates"). All mortgages underlying a particular GNMA I Certificate must
have the same annual interest rate (except for pools of mortgages secured by
mobile homes). The annual interest rate on each GNMA I Certificate is one-half
percentage point less than the annual interest rate on the mortgage loans
included in the pool of mortgages backing such GNMA I Certificate. Mortgages
underlying a particular GNMA II Certificate may have annual interest rates that
vary from each other by up to one percentage point. The annual interest rate on
each GNMA II Certificate will be between one-half percentage point and one and
one-half percentage points less than the highest annual interest rate on the
mortgage loans included in the pool of mortgages backing such GNMA II
Certificate.
 
     GNMA will have approved the issuance of each of the GNMA Certificates in
accordance with a guaranty agreement between GNMA and the servicer of the
mortgage loans underlying such GNMA Certificate. Pursuant to such agreement, the
servicer is required to advance its own funds in order to make timely payments
of all amounts due on the GNMA Certificate, even if the payments received by
such servicer on the mortgage loans backing the GNMA Certificate are less than
the amounts due on such GNMA Certificate. If a servicer is unable to make
payments on a GNMA Certificate as it becomes due, it must promptly notify GNMA
and request GNMA to make such payment. Upon such notification and request, GNMA
will make such payments directly to the registered holder of the GNMA
Certificate. In the event no payment is made by such servicer and such servicer
fails to notify and request GNMA to make such payment, the registered holder of
the GNMA Certificate has recourse only against GNMA to obtain such payment. The
registered holder of the GNMA Certificates included in a Pool is entitled to
proceed directly against GNMA under the terms of each GNMA Certificate or the
guaranty agreement or contract relating to such GNMA Certificate for any amounts
that are not paid when due under each GNMA Certificate.
 
     As described above, the GNMA Certificates included in a Pool, and the
related underlying mortgage loans, may have characteristics and terms different
from those described above. Any such different characteristics and terms will be
described in the related Supplement.
 
     FHLMC.  FHLMC is a corporate instrumentality of the United States created
pursuant to Title III of the Emergency Home Finance Act of 1970, as amended (the
"FHLMC Act"). FHLMC's common stock is owned by the Federal Home Loan Banks, and
its preferred stock is owned by the stockholders of such Federal Home Loan
Banks. FHLMC was established primarily for the purpose of increasing the
availability of mortgage credit for the financing of urgently needed housing. It
seeks to provide an enhanced degree of liquidity for residential mortgage
investments primarily by assisting in the development of secondary markets for
conventional mortgages. The principal activity of FHLMC currently consists of
the purchase of first lien conventional residential mortgage loans or
participation interests in such mortgage loans and the resale of the mortgage
loans so purchased in the form of mortgage securities. FHLMC is confined to
purchasing, so far as practicable, conventional mortgage loans and participation
interests therein which it deems to be of such
 
                                       15
<PAGE>   84
 
quality, type and class as to meet generally the purchase standards imposed by
private institutional mortgage investors.
 
     FHLMC Certificates.  FHLMC Certificates ("FHLMC Certificates") represent an
undivided interest in a group of mortgage loans purchased by FHLMC. Mortgage
loans underlying the FHLMC Certificates included in a Pool will consist of
fixed- or adjustable-rate mortgage loans with original terms to maturity of from
10 to 30 years, all of which are secured by first liens on one- to four-family
residential properties or properties containing five or more units and designed
primarily for residential use.
 
     FHLMC Certificates are issued and maintained and may be transferred only on
the book-entry system of a Federal Reserve Bank and may only be held of record
by entities eligible to maintain book-entry accounts at a Federal Reserve Bank.
Beneficial owners will hold FHLMC Certificates ordinarily through one or more
financial intermediaries. The rights of a beneficial owner of a FHLMC
Certificate against FHLMC or a Federal Reserve Bank may be exercised only
through the Federal Reserve Bank on whose book-entry system such Certificate is
held.
 
     Under its Cash and Guarantor programs, FHLMC guarantees to each registered
holder of a FHLMC Certificate the timely payment of interest at the rate
provided for by such FHLMC Certificate on the registered holder's pro rata share
of the unpaid principal balance outstanding of the related mortgage loans,
whether or not received. FHLMC also guarantees to each registered holder of a
FHLMC Certificate ultimate collection of all principal of the related mortgage
loans, without any offset or deduction, to the extent of such holder's pro rata
share thereof, but does not, except if and to the extent specified in the
related Supplement for a Series of Certificates, guarantee the timely payment of
scheduled principal. Pursuant to its guarantees, FHLMC indemnifies holders of
FHLMC Certificates against any diminution in principal by reason of charges for
property repairs, maintenance and foreclosure. FHLMC may remit the amount due on
account of its guarantee of ultimate collection of principal at any time after
default on an underlying mortgage loan, but not later than 30 days following (i)
foreclosure sale, (ii) payment of the claim by any mortgage insurer, or (iii)
the expiration of any right of redemption, whichever occurs later, but in any
event no later than one year after demand has been made upon the mortgagor for
accelerated payment of principal. In taking actions regarding the collection of
principal after default on the mortgage loans underlying FHLMC Certificates,
including the timing of demand for acceleration, FHLMC reserves the right to
exercise its servicing judgment with respect to the mortgages in the same manner
as for mortgages that it has purchased but not sold.
 
     Under FHLMC's Cash Program, there is no limitation on the amount by which
interest rates on the mortgage loans underlying a FHLMC Certificate may exceed
the interest rate on the FHLMC Certificate. For FHLMC Pools formed under FHLMC's
Guarantor Program having pool numbers beginning with 18-012, the range between
the lowest and highest annual interest rates on the mortgage loans does not
exceed two percentage points.
 
     Under its Gold PC Program, FHLMC guarantees to each registered holder of a
FHLMC Certificate the timely payment of interest calculated in the same manner
as described above, as well as timely installments of scheduled principal based
on the difference between the pool factor published in the month preceding the
month of distribution and the pool factor published in such month of
distribution for the related FHLMC Certificate.
 
     FHLMC Certificates are not guaranteed by the United States or by any
Federal Home Loan Bank and do not constitute debts or obligations of the United
States or any Federal Home Loan Bank. The obligations of FHLMC under its
guarantee are obligations solely of FHLMC and are not backed by, nor entitled
to, the full faith and credit of the United States.
 
     As described above, the FHLMC Certificates included in a Pool, and the
related underlying mortgage loans, may have characteristics and terms different
from those described above. Any such different characteristics and terms will be
described in the related Supplement.
 
     FNMA.  FNMA is a federally chartered and stockholder owned corporation
organized and existing under the Federal National Mortgage Association Charter
Act, as amended. FNMA was originally established in 1938 as a United States
government agency to provide supplemental liquidity to the mortgage market
 
                                       16
<PAGE>   85
 
and was transformed into a stockholder owned and privately managed corporation
by legislation enacted in 1968.
 
     FNMA provides funds to the mortgage market primarily by purchasing home
mortgage loans from local lenders, thereby replenishing their funds for
additional lending. FNMA acquires funds to purchase home mortgage loans from
many capital market investors that may not ordinarily invest in mortgages,
thereby expanding the total amount of funds available for housing. Operating
nationwide, FNMA helps to redistribute mortgage funds from capital-surplus to
capital-short areas. In addition, FNMA issues mortgage-backed securities
primarily in exchange for pools of mortgage loans from lenders.
 
     FNMA Certificates.  FNMA Certificates ("FNMA Certificates") represent
fractional interests in a pool of mortgage loans formed by FNMA.
 
     FNMA guarantees to each registered holder of a FNMA Certificate that it
will distribute amounts representing scheduled principal and interest at the
applicable pass-through rate on the underlying mortgage loans, whether or not
received, and such holder's proportionate share of the full principal amount of
any foreclosed or other finally liquidated mortgage loan, whether or not such
principal amount is actually recovered. If FNMA were unable to perform such
obligations, distributions on FNMA Certificates would consist solely of payments
and other recoveries on the underlying mortgage loans and, accordingly,
delinquencies and defaults would affect monthly distributions to holders of FNMA
Certificates. The obligations of FNMA under its guarantees are obligations
solely of FNMA and are not backed by, nor entitled to, the full faith and credit
of the United States.
 
     As described above, the FNMA Certificates included in a Pool, and the
related underlying mortgage loans, may have characteristics and terms different
from those described above. Any such different characteristics and terms will be
described in the related Supplement.
 
     Private Certificates.  Private Certificates ("Private Certificates") may
consist of (a) mortgage pass-through certificates or participation certificates
representing beneficial interests in loans of the type that would otherwise be
eligible to be Mortgage Loans (the "Underlying Loans") or (b) collateralized
mortgage obligations secured by Underlying Loans. Private Certificates may
include stripped mortgage-backed securities representing an undivided interest
in all or a part of either the principal distributions (but not the interest
distributions) or the interest distributions (but not the principal
distributions) or in some portion of the principal and interest distributions
(but not all such distributions) of certain mortgage loans. The Private
Certificates will have previously been (1) offered and distributed to the public
pursuant to an effective registration statement or (2) purchased in a
transaction not involving any public offering from a person who is not an
affiliate of the issuer of such securities at the time of sale (nor an affiliate
thereof at any time during the three preceding months); provided that a period
of three years has elapsed since the later of the date the securities were
acquired from the issuer or an affiliate thereof. Although individual Underlying
Loans may be insured or guaranteed by the United States or an agency or
instrumentality thereof, they need not be, and the Private Certificates
themselves will not be so insured or guaranteed. Unless otherwise specified in
the related Supplement, the seller/servicer of the underlying mortgage loans
will have entered into a pooling and servicing agreement, an indenture or
similar agreement (a "PC Agreement") with the trustee under such PC Agreement
(the "PC Trustee"). The PC Trustee or its agent, or a custodian, will possess
the mortgage loans underlying such Private Certificates. The mortgage loans
underlying the Private Certificates may be subserviced by one or more loan
servicing institutions under the supervision of a master servicer (the "PC
Servicer").
 
     The sponsor of the Private Certificates (the "PC Sponsor") will be a
financial institution or other entity which is or has affiliates which are
engaged generally in the business of mortgage lending, a public agency or
instrumentality of a state, local or federal government, or a limited purpose
corporation organized for the purpose of, among other things, establishing
trusts and acquiring and selling mortgage loans to such trusts and selling
beneficial interests in such trusts. The PC Sponsor may be an affiliate of the
Sponsor. The obligations of the PC Sponsor will generally be limited to certain
representations and warranties with respect to the assets conveyed by it to the
related trust. Unless otherwise specified in the related Supplement, the PC
Sponsor will not have guaranteed any of the assets conveyed to the related trust
or any of the Private Certificates issued
 
                                       17
<PAGE>   86
 
under the PC Agreement. Additionally, although the mortgage loans underlying the
Private Certificates may be guaranteed by an agency or instrumentality of the
United States, the Private Certificates themselves will not be so guaranteed.
 
     The Sponsor will acquire Private Certificates in open market transactions
or in privately negotiated transactions which may be through affiliates.
 
     The Supplement for a Series for which the Pool includes Private
Certificates will specify (such disclosure may be on an approximate basis and
will be as of the date specified in the related Supplement) to the extent
relevant and to the extent such information is reasonably available to the
Sponsor and the Sponsor reasonably believes such information to be reliable (i)
the aggregate approximate principal amount and type of the Private Certificates
to be included in the Pool; (ii) certain characteristics of the mortgage loans
that comprise the underlying assets for the Private Certificates including (A)
the payment features of such underlying mortgage loans, (B) the approximate
aggregate principal balance, if known, of underlying mortgage loans insured or
guaranteed by a governmental entity, (C) the servicing fee or range of servicing
fees with respect to the underlying mortgage loans and (D) the minimum and
maximum stated maturities of the underlying mortgage loans at origination; (iii)
the maximum original term-to-stated maturity of the Private Certificates; (iv)
the weighted average term-to-stated maturity of the Private Certificates; (v)
the pass-through or certificate rate of the Private Certificates; (vi) the
weighted average pass-through or certificate rate of the Private Certificates;
(vii) the PC Sponsor, the PC Trustee and the PC Servicer; (viii) certain
characteristics of credit support, if any, such as reserve funds, insurance
policies, surety bonds, letters of credit or guaranties relating to the mortgage
loans underlying the Private Certificates or to such Private Certificates
themselves; (ix) the terms on which the underlying mortgage loans for such
Private Certificates may, or are required to, be purchased prior to their stated
maturity or the stated maturity of the Private Certificates; and (x) the terms
on which mortgage loans may be substituted for those originally underlying the
Private Certificates.
 
CERTIFICATE ACCOUNT
 
     The Servicer or other entity identified in the related Supplement will, as
to each Series of Certificates, establish and maintain a Certificate Account for
the benefit of the Trustee and holders of the Certificates of such Series for
receipt of (i) each distribution or monthly payment, as the case may be, made to
the Trustee with respect to the Mortgage Assets, (ii) the amount of cash, if
any, specified in the related Pooling Agreement to be initially deposited
therein, (iii) the amount of cash, if any, withdrawn from any related Reserve
Fund or other fund, and (iv) the reinvestment income thereon, if any. The
Pooling Agreement for a Series may authorize the Trustee to invest the funds in
the Certificate Account in certain investments ("Eligible Investments") that
will qualify as "permitted investments" under Section 860G(a)(5) of the Code in
the case of REMIC Certificates. The Eligible Investments will generally mature
not later than the business day immediately preceding the next Distribution Date
for such Series (or, in certain cases, on such Distribution Date). Eligible
Investments include, among other investments, obligations of the United States
and certain agencies thereof, federal funds, certificates of deposit, commercial
paper carrying the ratings specified in the related Pooling Agreement of each
Rating Agency rating the Certificates of such Series that has rated such
commercial paper, demand and time deposits and banker's acceptances sold by
eligible commercial banks, certain repurchase agreements of United States
government securities and certain Minimum Reinvestment Agreements. Reinvestment
earnings, if any, on funds in the Certificate Account generally will belong to
the Servicer.
 
MINIMUM PREPAYMENT AGREEMENT
 
     The Sponsor may enter into an agreement (a "Minimum Prepayment Agreement")
with an institution meeting the criteria of the Rating Agency rating the related
Series to enable the Trustee to make distributions of principal on the
Certificates of such Series in accordance with a schedule set forth in the
related Supplement. Funds will be provided under the Minimum Prepayment
Agreement in the event that aggregate scheduled principal payments and
prepayments on the Mortgage Assets included in the related Pool were not
sufficient to make distributions in reduction of the Certificate Balance of such
Certificates in accordance with such Minimum Prepayment Schedule. Such Minimum
Prepayment Agreement may obligate the institution
 
                                       18
<PAGE>   87
 
to purchase, from time to time, Mortgage Assets included in the Pool pursuant to
a selection process set forth in such agreement for an amount specified in the
related Supplement.
 
     The related Supplement will describe the terms and conditions of any
Minimum Prepayment Agreement if a Minimum Prepayment Agreement is to be a part
of the Pool.
 
MINIMUM REINVESTMENT AGREEMENT
 
     The Sponsor may enter into an agreement (a "Minimum Reinvestment
Agreement") with an institution meeting the criteria of the Rating Agency rating
the related Series. Amounts required to be deposited in any account or fund for
a related Series will be invested pursuant to such agreement. If a Minimum
Reinvestment Agreement is entered into with respect to a Series of Certificates,
reinvestment earnings on funds in the Certificate Account will not belong to the
Servicer as additional servicing compensation but will be available to make
distributions on the Certificates in accordance with their terms. The applicable
interest rates for funds invested under such agreement will be described in the
related Supplement if a Minimum Reinvestment Agreement is to be a part of the

GENERAL
 
     Each Series of Certificates will be issued pursuant to a separate Pooling
Agreement among the Sponsor, the Seller, the Trustee and the Servicer, if such
Series relates to Mortgage Loans. A form of Pooling Agreement is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
following summaries describe certain provisions that may appear in each Pooling
Agreement. The Supplement for a Series of Certificates will describe any
provision of the Agreement relating to such Series that materially differs from
the description thereof contained in this Prospectus. The summaries do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all of the provisions of the Pooling Agreement and the
Supplement related to a particular Series of Certificates. References herein to
a Trustee or the Servicer include, unless otherwise specified, any agents acting
on behalf of such Trustee or any subcontractor of the Servicer, any of which
agents or subcontractors may be one of their affiliates.
 
     The Certificates are issuable in Series, each evidencing the entire
ownership interest in a Pool of assets consisting primarily of Mortgage Assets.
The Certificates of each Series will be issued in fully registered form or
book-entry form and will be issued in the authorized denominations for each
class specified in the related Supplement, will evidence specified beneficial
ownership interests in the related Pool created pursuant to the related Pooling
Agreement and will not be entitled to payments in respect of the assets included
in any other Pool established by the Sponsor. The transfer of the Certificates
may be registered, and the Certificates may be exchanged, at the office or
agency of the Trustee specified in the related Supplement without the payment of
any service charge other than any tax or governmental charge payable in
connection with such registration of transfer or exchange. The transfer of any
class of a Series of Certificates may be subject to the satisfaction of certain
conditions set forth in the related Supplement. The Certificates will not
represent obligations of the Sponsor or any affiliate of the Sponsor. The
Mortgage Assets will not be insured or guaranteed by any governmental entity or
other person, unless otherwise specified in the related Supplement. Any
qualifications on direct or indirect ownership of Residual Certificates, as well
as restrictions on the transfer of such Residual Certificates, will be set forth
in the related Supplement.
 
     Each Series of Certificates will be issued in one or more classes. Each
class of Certificates of a Series will evidence beneficial ownership of a
specified percentage (which may be 0%) or portion of future interest payments
and a specified percentage (which may be 0%) or portion of future principal
payments on the Mortgage Assets in the related Pool. A Series of Certificates
may include one or more classes that are senior in right to payment to one or
more other classes of Certificates of such Series. Certain Series or classes of
Certificates may be covered by insurance policies, surety bonds or other forms
of credit support, in each case as described herein and in the related
Supplement. One or more classes of Certificates of a Series may be entitled to
receive distributions of principal, interest or any combination thereof.
Distributions on one or more
 
                                       19
<PAGE>   88
 
classes of a Series of Certificates may be made prior to one or more other
classes, after the occurrence of specified events, in accordance with a schedule
or formula, on the basis of collections from designated portions of the Mortgage
Assets in the related Pool, or on a different basis, in each case as specified
in the related Supplement. The timing and amounts of such distributions may vary
among classes or over time as specified in the related Supplement.
 
DISTRIBUTIONS
 
     Distributions of principal of and interest on the Certificates of a Series
will be made (to the extent of funds available therefor) on the dates specified
therefor in the related Supplement (each, a "Distribution Date"), and allocated
to the classes of such Series at the Certificate Rates, in the amounts and in
the order specified in the related Supplement. Distributions will be made by
wire transfer (in the case of Certificates which are of a certain minimum
denomination, as specified in the related Supplement) or by check mailed to
record holders of such Certificates as of the related Record Date (as specified
in the related Supplement) at their addresses appearing on the Certificate
Register, except that the final distribution of principal will be made only upon
presentation and surrender of such Certificate at the office or agency of the
Paying Agent for such Certificate specified in the related Supplement. With
respect to any Distribution Date, the "Record Date" will be the close of
business on (i) the last business day of the preceding month, (ii) with respect
to the first Distribution Date for a Series, if the Closing Date of the Series
occurs in the month following the Cut-Off Date, such Closing Date or (iii) such
other date as is specified in the related Supplement. Notice will be mailed
before the Distribution Date on which the final distribution is expected to be
made to the holder of such Certificate. In the event the Certificates of a
Series are issued in book-entry form, distributions on such Certificates,
including the final distribution in retirement of such Certificates, will be
made through the facilities of a depository in accordance with its usual
procedures in the manner described in the related Supplement.
 
     Distributions of principal of and interest on the Certificates will be made
by the Trustee out of the Certificate Account established under the Pooling
Agreement. All distributions on the Mortgage Certificates, if any, included in
the Pool for a Series, remittances on the Mortgage Loans by the Servicer
pursuant to the Pooling Agreement, together with any reinvestment income (if so
specified in the related Supplement) thereon and amounts withdrawn from any
Reserve Fund or other fund or payments in respect of other credit support and
required to be so deposited, will be deposited directly into the Certificate
Account and thereafter will be available (except for funds held for future
distribution and for funds payable to the Servicer) to make distributions on
Certificates of such Series on the next succeeding Distribution Date. See "The
Pools -- Certificate Account" and "Servicing of Mortgage Loans -- Payments on
Mortgage Loans" herein.
 
     Interest.  Interest will accrue on the aggregate Certificate Balance (or,
in the case of IO Certificates, the aggregate notional amount) of each class of
Certificates (the "Class Certificate Balance") entitled to interest at the
Certificate Rate (which may be a fixed rate or a rate adjustable as specified in
such Supplement) during each Interest Accrual Period specified in such
Supplement. The "Interest Accrual Period" with respect to any Distribution Date
shall be the period from (and including) the first day of the month preceding
the month of such Distribution Date (or, in the case of the first Distribution
Date, from the Closing Date) through the last day of such preceding month, or
such other period as may be specified in the related Supplement. To the extent
funds are available therefor, interest accrued during each such Interest Accrual
Period on each class of Certificates entitled to interest (other than a class of
Certificates that provides for interest that accrues, but is not currently
payable, referred to hereafter as "Accrual Certificates") will be distributable
on the Distribution Dates specified in the related Supplement until the Class
Certificate Balance of such class is reduced to zero or, in the case of
Certificates entitled only to distributions allocable to interest, until the
aggregate notional amount of such Certificates is reduced to zero or for the
period of time designated in the related Supplement. Unless otherwise specified
in the related Supplement, distributions allocable to interest on each Notional
Amount Certificate that is not entitled to distributions allocable to principal
will be calculated based on the notional amount of such Notional Amount
Certificate. The notional amount of a Notional Amount Certificate will not
evidence an interest in or entitlement to distributions allocable to principal
but will be used solely for convenience in expressing the calculation of
interest and for certain other purposes. Unless otherwise specified
 
                                       20
<PAGE>   89
 
in the related Supplement, interest on the Certificates of each class will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
 
     Distributions of interest on each class of Accrual Certificates will
commence only after the occurrence of the events specified in the related
Supplement and, prior to such time, such interest will be added to the Class
Certificate Balance of such class of Accrual Certificates. Any such class of
Accrual Certificates will thereafter accrue interest on its outstanding Class
Certificate Balance as so adjusted.
 
     Principal.  Unless otherwise specified in the related Supplement, the Class
Certificate Balance of any class of Certificates entitled to distributions of
principal will be the original Class Certificate Balance of such class of
Certificates specified in such Supplement, reduced by all distributions reported
to holders of such Certificates as allocable to principal and adjustments, if
any, in respect of losses and (i) in the case of Accrual Certificates, increased
by all interest accrued but not then distributable on such Accrual Certificates
and (ii) in the case of adjustable rate Certificates, subject to the effect of
negative amortization. The related Supplement will specify the method by which
the amount of principal to be distributed on the Certificates on each
Distribution Date will be calculated and the manner in which such amount will be
allocated among the classes of Certificates entitled to distributions of
principal.
 
     Each class of Certificates of a Series (except for IO Certificates) will
(to the extent of funds available therefor) receive distributions of principal
in the amounts, at the times and in the manner specified in the related
Supplement until its initial aggregate Certificate Balance has been fully
amortized. Allocations of distributions of principal will be made to the
Certificates of each class, during the periods and in the order specified in the
related Supplement. Unless otherwise specified in the related Supplement,
distributions will be made pro rata among the Certificates of each class then
entitled to receive such distributions.
 
     The "Last Scheduled Distribution Date" for a class of Certificates is the
latest date as of which the Class Certificate Balance of the Certificates of
such class is expected to be fully amortized, either based on the assumptions
that all scheduled payments (with no prepayments) on the Mortgage Assets in the
related Pool are timely received and, if applicable, that all such scheduled
payments are reinvested on receipt at the rate or rates specified in the related
Supplement at which amounts in the Certificate Account are assumed to earn
interest (the "Assumed Reinvestment Rate") or, if a Minimum Prepayment Agreement
is entered into with respect to such Series that payments on the related
Mortgage Assets are received, in accordance with a minimum prepayment rate or
schedule as set forth in the related Supplement. (If an Assumed Reinvestment
Rate is specified for a Series of Certificates, reinvestment earnings on funds
in the Certificate Account will not belong to the Servicer as additional
servicing compensation. Such amounts will be part of the Pool and will be
available to make distributions on the related Certificates.)
 
CATEGORIES OF CLASSES OF CERTIFICATES
 
     In general, the classes of certificates of each Series fall into different
categories. The following chart identifies and generally defines certain of the
more typical categories. The Supplement for a series of Certificates may
identify the classes which comprise such Series by reference to the following
categories.
 
                                PRINCIPAL TYPES
 
<TABLE>

 CATEGORIES OF CLASSES                               DEFINITION
- -----------------------  -------------------------------------------------------------------
<S>                      <C>
Accretion Directed.....  A class that receives principal payments from the accreted interest
                         from specified Accrual Classes. An Accretion Directed Class also
                         may receive principal payments from principal paid on the Mortgage
                         Assets or other assets of the Pool for the related Series.
Component
  Certificates.........  A class consisting of "Components." The Components of a class of
                         Component Certificates may have different principal and/or interest
                         payment characteristics but together constitute a single class.
                         Each Component of a class of Component Certificates may be
                         identified as falling into one or more of the categories in this
                         chart.

 CATEGORIES OF CLASSES                               DEFINITION
- -----------------------  -------------------------------------------------------------------
<S>                      <C>
Notional Amount
  Certificates.........  A class having no principal balance and bearing interest on the
                         related notional amount. The notional amount is used for purposes
                         of the determination of interest distributions.
Planned Principal Class
  (also sometimes
  referred to
  as "PACs")...........  A class that is designed to receive principal payments using a
                         predetermined principal balance schedule derived by assuming two
                         constant prepayment rates for the underlying Mortgage Assets. These
                         two rates are the endpoints for the "structuring range" for the
                         Planned Principal Class. The Planned Principal Classes in any
                         Series of Certificates may be subdivided into different categories
                         (e.g., Primary Planned Principal Classes, Secondary Planned
                         Principal Classes and so forth) having different effective
                         structuring ranges and different principal payment priorities. The
                         structuring range for the Secondary Planned Principal Class of a
                         Series of Certificates will be narrower than that for the Primary
                         Planned Principal Class of such Series.
Scheduled Principal
  Class................  A class that is designed to receive principal payments using a
                         predetermined principal balance schedule but is not designated as a
                         Planned Principal Class or Targeted Principal Class. In many cases,
                         the schedule is derived by assuming two constant prepayment rates
                         for the Mortgage Assets. These two rates are the endpoints for the
                         "structuring range" for the Scheduled Principal Class.
Sequential Pay.........  Classes that receive principal payments in a prescribed sequence,
                         that do not have predetermined principal balance schedules and that
                         under all circumstances receive payments of principal continuously
                         from the first Distribution Date on which they receive principal
                         until they are retired. A single class that receives principal
                         payments before or after all other classes in the same Series of
                         Certificates may be identified as a Sequential Pay Class.
Strip..................  A class that receives a constant proportion, or "strip," of the
                         principal payments on the Mortgage Assets. The constant proportion
                         of such principal payments may or may not vary for each Mortgage
                         Asset included in the Pool and will be calculated in the manner
                         described in the related Supplement. Such Classes may also receive
                         payments of interest.
Support Class (also
  sometimes referred to
  as "companion
  classes")............  A class that receives principal payments on any Distribution Date
                         only if scheduled payments have been made on specified Planned
                         Principal Classes, Targeted Principal Classes and/or Scheduled
                         Principal Classes.
Targeted Principal
  Class (also sometimes
  referred to
  as "TACs")...........  A class that is designed to receive principal payments using a
                         predetermined principal balance schedule derived by assuming a
                         single constant prepayment rate for the Mortgage Assets.

 CATEGORIES OF CLASSES                               DEFINITION
- -----------------------  -------------------------------------------------------------------
<S>                      <C>
Accrual................  A class that accretes the amount of accrued interest otherwise
                         distributable on such class, which amount will be added as
                         principal to the principal balance of such class on each applicable
                         Distribution Date. Such accretion may continue until some specified
                         event has occurred or until such class of Accrual Certificates is
                         retired.
Fixed Rate.............  A class with a Certificate Rate that is fixed throughout the life
                         of the class.
Floating Rate..........  A class with a Certificate Rate that resets periodically based upon
                         a designated Index and that varies directly with changes in such
                         Index.
Inverse Floating         A class with a Certificate Rate that resets periodically based upon
  Rate.................  a designated Index and that varies inversely with changes in such
                         Index.
IO.....................  Certificates that receive some or all of the interest payments made
                         on the Mortgage Assets and little or no principal. IO Certificates
                         have either a nominal principal balance or a notional amount. A
                         nominal principal balance represents actual principal that will be
                         paid on such Certificates. It is referred to as nominal since it is
                         extremely small compared to other classes. A notional amount is the
                         amount used as a reference to calculate the amount of interest due
                         on an IO Certificate that is not entitled to any distributions in
                         respect of principal.
Partial Accrual........  A class that accretes a portion of the amount of accrued interest
                         thereon, which amount will be added to the principal balance of
                         such class on each applicable Distribution Date, with the remainder
                         of such accrued interest to be distributed currently as interest on
                         such class. Such accretion may continue until a specified event has
                         occurred or until such class of Partial Accrual Certificates is
                         retired.
PO.....................  A class that does not bear interest and is entitled to receive only
                         distributions in respect of principal.
Variable Rate..........  A class with a Certificate Rate that resets periodically and is
                         calculated by reference to the rate or rates of interest applicable
                         to specified assets or instruments (e.g., the Mortgage Rates borne
                         by the Mortgage Loans in the related Pool).
</TABLE>
 
RESIDUAL CERTIFICATES
 
     A Series of REMIC Certificates will include a class of Residual
Certificates representing the right to receive on each Distribution Date, in
addition to any other distributions to which they are entitled in accordance
with their terms and as described in the related Supplement, the excess of the
sum of distributions, payments and other amounts received over the sum of (i)
the amount required to be distributed to Certificateholders on such Distribution
Date and (ii) certain expenses, all as more specifically described in the
related Supplement. In addition, after the aggregate Class Certificate Balances
of all classes of Regular Certificates has been fully amortized, holders of the
Residual Certificates will be the sole owners of the related Pool and will have
sole rights with respect to the Mortgage Assets and other assets remaining in
such Pool. Some or all of the Residual Certificates of a Series may be offered
by this Prospectus and the related Supplement; if so, the terms of such Residual
Certificates will be described in such Supplement. Any qualifications on direct
or indirect ownership of Residual Certificates offered hereby and by the related
Supplement, as well as restrictions on the transfer of such Residual
Certificates, will be set forth in the related Supplement. If such Residual
Certificates are not so offered, the Sponsor may (but need not) sell some or all
of such Residual Certificates on or after the date of original issuance of such
Series in transactions exempt from registration under the Securities Act and
otherwise under circumstances that will not adversely affect the REMIC status of
the Pool.

<PAGE>   92
 
ADVANCES
 
     The Servicer may be obligated or have the right at its option under the
Pooling Agreement for a Series of Certificates backed in whole or in part by
Mortgage Loans to advance, on or prior to any Distribution Date, its own funds
and/or funds being held in the Certificate Account for future distribution to
Certificateholders in an amount up to the aggregate of interest and principal
installments on the Mortgage Loans becoming due and payable on the Due Date in
any month and delinquent on the close of business on the following Determination
Date. The Servicer may be obligated to make such Advances only to the extent any
such Advance, in the judgment of the Servicer made on the Determination Date,
will be reimbursable from late payments made by Mortgagors, payments under any
Primary Mortgage Insurance Policy or other form of credit support or proceeds of
liquidation. Any Servicer funds thus advanced are reimbursable to the Servicer
from cash in the Certificate Account to the extent that the Servicer shall
determine that any such Advances previously made are not ultimately recoverable
from the sources described above.
 
     In making Advances, the Servicer will endeavor to maintain a regular flow
of scheduled interest and principal payments to holders of the related classes
of Certificates, rather than to guarantee or insure against losses. If Advances
are made by the Servicer from funds being held for future distribution to
Certificateholders, the Servicer will replace such funds on or before any future
Distribution Date to the extent that funds in the Certificate Account on such
Distribution Date would be less than the amount required to be available for
distributions to Certificateholders on such date.
 
     The Servicer may also be obligated to make advances, to the extent
recoverable out of insurance proceeds, liquidation proceeds or otherwise, in
respect of certain taxes and insurance premiums not paid by Mortgagors on a
timely basis. Funds so advanced are reimbursable to the Servicer to the extent
permitted by the Pooling Agreement. If specified in the related Supplement, the
obligations of the Servicer to make Advances may be supported by a cash advance
reserve fund, a surety bond or other arrangement, in each case as described in
such Supplement.
 
REPORTS TO CERTIFICATEHOLDERS
 
     Prior to or concurrently with each distribution on a Distribution Date and
except as otherwise set forth in the related Supplement, the Servicer or the
Trustee will furnish to each Certificateholder of record of the related Series a
statement setting forth, to the extent applicable to such Series of
Certificates, among other things:
 
          (i) the amount of such distribution allocable to principal, separately
     identifying the aggregate amount of any Principal Prepayments and, if so
     specified in the related Supplement, prepayment penalties included therein;
 
          (ii) the amount of such distribution allocable to interest;
 
          (iii) the amount of any Advance;
 
          (iv) the aggregate amount withdrawn from the Reserve Fund, if any,
     that is included in the amounts distributed to Certificateholders;
 
          (v) the Class Certificate Balance or notional amount of each class of
     the related Series after giving effect to the distribution of principal on
     such Distribution Date;
 
          (vi) the percentage of principal payments on the Mortgage Assets
     (excluding prepayments), if any, which each such class will be entitled to
     receive on the following Distribution Date;
 
          (vii) the percentage of Principal Prepayments with respect to the
     Mortgage Assets, if any, which each such class will be entitled to receive
     on the following Distribution Date;
 
          (viii) the related amount of the servicing compensation retained or
     withdrawn from the Certificate Account by the Servicer, and the amount of
     additional servicing compensation received by the Servicer attributable to
     penalties, fees, excess Liquidation Proceeds and other similar charges and
     items;
 
                                       24
<PAGE>   93
 
          (ix) the number and aggregate principal balances of Mortgage Loans (A)
     delinquent (exclusive of Mortgage Loans in foreclosure) (1) 1 to 30 days,
     (2) 31 to 60 days, (3) 61 to 90 days and (4) 91 or more days and (B) in
     foreclosure and delinquent, as of the close of business on the last day of
     the calendar month preceding such Distribution Date;
 
          (x) the book value of any real estate acquired through foreclosure or
     grant of a deed in lieu of foreclosure ("REO Property");
 
          (xi) the Certificate Rate, if adjusted from the date of the last
     statement, of any such class expected to be applicable to the next
     distribution to such class;
 
          (xii) if applicable, the amount remaining in the Reserve Fund at the
     close of business on the Distribution Date;
 
          (xiii) the Certificate Rate as of the day prior to the immediately
     preceding Distribution Date; and
 
          (xiv) any amounts remaining under letters of credit, pool policies or
     other forms of credit support.
 
     Where applicable, any amount set forth above may be expressed as a dollar
amount per single Certificate of the relevant class specified in the related
Supplement. The report to Certificateholders for any Series of Certificates may
include additional or other information of a similar nature to that specified
above.
 
     In addition, within a reasonable period of time after the end of each
calendar year, the Servicer or the Trustee will mail to each Certificateholder
of record at any time during such calendar year a report (a) as to the aggregate
of amounts reported pursuant to (i) and (ii) for such calendar year or, in the
event such person was a Certificateholder of record during a portion of such
calendar year, for the applicable portion of such year and (b) such other
customary information as may be deemed necessary or desirable for
Certificateholders to prepare their tax returns.
 
SPECIAL DISTRIBUTIONS
 
     REMIC Certificates of a Series with Distribution Dates that are not monthly
may receive distributions ("Special Distributions") of principal on any date (a
"Special Distribution Date") specified in the related Supplement in any month in
which a Distribution Date does not occur if it is determined, based on
assumptions specified in the related Pooling Agreement, that the amount of cash
estimated to be on deposit in the Certificate Account on the date specified in
such Supplement, together with any funds available for withdrawal from any
related fund, is not sufficient to make the distributions of interest and
principal scheduled to be made on such date. Special Distributions will be made
in the same priority and manner as distributions are to be made on the next
Distribution Date.
 
                                 CREDIT SUPPORT
 
GENERAL
 
     Credit support may be provided with respect to one or more classes of a
Series of Certificates or with respect to the Mortgage Assets in the related
Pool. Credit support may be in the form of a limited financial guaranty policy
issued by an entity named in the related Supplement, the subordination of one or
more classes of the Certificates of such Series, the establishment of one or
more reserve funds, the use of a cross-support feature, the use of a mortgage
pool insurance policy, bankruptcy bond, special hazard insurance policy, surety
bond, letter of credit, guaranteed investment contract or other method of credit
support described in the related Supplement, or any combination of the
foregoing. Unless otherwise specified in the related Supplement, no credit
support will provide protection against all risks of loss or guarantee repayment
of the entire principal balance of the Certificates and interest thereon. If
losses occur which exceed the amount covered by credit support or which are not
covered by the credit support, Certificateholders will bear their allocable
share of any deficiencies.
 
                                       25
<PAGE>   94
 
     If specified in the related Supplement, the coverage provided by one or
more forms of credit support may apply concurrently to two or more related
Pools. If applicable, the related Supplement will identify the Pools to which
such credit support relates and the manner of determining the amount of the
coverage provided thereby and of the application of such coverage to the
identified Pools.
 
SUBORDINATION
 
     If so specified in the related Supplement, the rights of holders of one or
more classes of Subordinate Certificates will be subordinate to the rights of
holders of one or more classes of Senior Certificates of such Series to
distributions in respect of scheduled principal, Principal Prepayments, interest
or any combination thereof that otherwise would have been payable to holders of
Subordinate Certificates under the circumstances and to the extent specified in
the related Supplement. If so specified in the related Supplement, certain
classes of Subordinate Certificates may be senior to other classes of
Subordinate Certificates and be rated investment grade ("Mezzanine
Certificates"). If specified in the related Supplement, delays in receipt of
scheduled payments on the Mortgage Assets and certain losses with respect to the
Mortgage Assets will be borne first by the various classes of Subordinate
Certificates and thereafter by the various classes of Senior Certificates, in
each case under the circumstances and subject to the limitations specified in
such related Supplement. The aggregate distributions in respect of delinquent
payments on the Mortgage Assets over the lives of the Certificates or at any
time, the aggregate losses in respect of Mortgage Assets which must be borne by
the Subordinate Certificates by virtue of subordination and the amount of
distributions otherwise distributable to Subordinate Certificateholders that
will be distributable to Senior Certificateholders on any Distribution Date may
be limited as specified in the related Supplement. If aggregate distributions in
respect of delinquent payments on the Mortgage Assets or aggregate losses in
respect of such Mortgage Assets were to exceed the amount specified in the
related Supplement, Senior Certificateholders would experience losses on their
Certificates.
 
     If specified in the related Supplement, various classes of Senior
Certificates and Subordinate Certificates may themselves be subordinate in their
right to receive certain distributions to other classes of Senior Certificates
and Subordinate Certificates, respectively, through a cross support mechanism or
otherwise.
 
     As between classes of Senior Certificates and as between classes of
Subordinate Certificates, distributions may be allocated among such classes (i)
in the order of their scheduled final distribution dates, (ii) in accordance
with a schedule or formula, (iii) in relation to the occurrence of events or
(iv) otherwise, in each case as specified in the related Supplement.
 
SURETY BONDS
 
     A surety bond or bonds may be obtained and maintained for a Series or
certain classes thereof which will, subject to certain conditions and
limitations, guaranty payments of all or limited amounts of principal and
interest due on all or certain of the classes of such Series.
 
MORTGAGE POOL INSURANCE POLICIES
 
     If specified in the related Supplement, a separate mortgage pool insurance
policy ("Mortgage Pool Insurance Policy") will be obtained for the Pool and
issued by the insurer (the "Pool Insurer") named in such Supplement. Each
Mortgage Pool Insurance Policy will, subject to the limitations described below,
cover loss by reason of default in payment on Mortgage Loans in the Pool in an
amount equal to a percentage specified in such Supplement of the aggregate
principal balance of such Mortgage Loans on the Cut-off Date. As more fully
described below, the Servicer will present claims thereunder to the Pool Insurer
on behalf of itself, the Trustee and Certificateholders. The Mortgage Pool
Insurance Policies, however, are not blanket policies against loss, since claims
thereunder may be made only respecting particular defaulted Mortgage Loans and
only upon satisfaction of certain conditions precedent described below. Unless
otherwise specified in the related Supplement, the Mortgage Pool Insurance
Policies will not cover losses due to a failure to pay or denial of a claim
under a Primary Mortgage Insurance Policy.
 
                                       26
<PAGE>   95
 
     Unless otherwise specified in the related Supplement, each Mortgage Pool
Insurance Policy will provide that no claims may be validly presented unless (i)
any required Primary Mortgage Insurance Policy is in effect for the defaulted
Mortgage Loan and a claim thereunder has been submitted and settled; (ii) hazard
insurance on the related Mortgaged Property has been kept in force and real
estate taxes and other protection and preservation expenses have been paid;
(iii) if there has been physical loss or damage to the Mortgaged Property, it
has been restored to its physical condition (reasonable wear and tear excepted)
at the time of issuance of the policy; and (iv) the insured has acquired good
and merchantable title to the Mortgaged Property free and clear of liens except
certain permitted encumbrances. Upon satisfaction of these conditions, the Pool
Insurer will have the option either (a) to purchase the Mortgaged Property at a
price equal to the principal balance of the related Mortgage Loan plus accrued
and unpaid interest at the Mortgage Rate to the date of such purchase and
certain expenses incurred by the Servicer on behalf of the Trustee and
Certificateholders or (b) to pay the amount by which the sum of the principal
balance of the defaulted Mortgage Loan plus accrued and unpaid interest at the
Mortgage Rate to the date of payment of the claim and the aforementioned
expenses exceeds the proceeds received from an approved sale of the Mortgaged
Property, in either case net of certain amounts paid or assumed to have been
paid under the related Primary Mortgage Insurance Policy. If any Mortgaged
Property is damaged, and proceeds, if any, from the related hazard insurance
policy or the applicable Special Hazard Insurance Policy are insufficient to
restore the damaged property to a condition sufficient to permit recovery under
the Mortgage Pool Insurance Policy, the Servicer will not be required to expend
its own funds to restore the damaged property unless it determines that (i) such
restoration will increase the proceeds to Certificateholders on liquidation of
the Mortgage Loan after reimbursement of the Servicer for its expenses and (ii)
such expenses will be recoverable by it through proceeds of the sale of the
Mortgaged Property or proceeds of the related Mortgage Pool Insurance Policy or
any related Primary Mortgage Insurance Policy.
 
     No Mortgage Pool Insurance Policy will insure (and many Primary Mortgage
Insurance Policies do not insure) against loss sustained by reason of a default
arising from, among other things, (i) fraud or negligence in the origination or
servicing of a Mortgage Loan, including misrepresentation by the Mortgagor, the
originator or persons involved in the origination thereof, or (ii) failure to
construct a Mortgaged Property in accordance with plans and specifications. A
failure of coverage attributable to one of the foregoing events might result in
a breach of the related Seller's representations described herein and, in such
event, might give rise to an obligation on the part of such Seller to repurchase
the defaulted Mortgage Loan if the breach cannot be cured by such Seller. No
Mortgage Pool Insurance Policy will cover (and many Primary Mortgage Insurance
Policies do not cover) a claim in respect of a defaulted Mortgage Loan occurring
when the servicer of such Mortgage Loan, at the time of default or thereafter,
was not approved by the applicable insurer.
 
     The original amount of coverage under each Mortgage Pool Insurance Policy
will be reduced over the life of the related Certificates by the aggregate
dollar amount of claims paid less the aggregate of the net amounts realized by
the Pool Insurer upon disposition of all foreclosed properties. The amount of
claims paid will include certain expenses incurred by the Servicer as well as
accrued interest on delinquent Mortgage Loans to the date of payment of the
claim, unless otherwise specified in the related Supplement. Accordingly, if
aggregate net claims paid under any Mortgage Pool Insurance Policy reach the
original policy limit, coverage under that Mortgage Pool Insurance Policy will
be exhausted and any further losses will be borne by Certificateholders.
 
FRAUD WAIVER
 
     If so specified in the related Supplement, a letter may be obtained from
the issuer of a Mortgage Pool Insurance Policy (the "Waiver Letter") waiving its
right to deny a claim or rescind coverage under the related Mortgage Pool
Insurance Policy by reason of fraud, dishonesty or misrepresentation in
connection with the origination of, or application for insurance for, the
related Mortgage Loan or the denial or adjustment of coverage under any related
Primary Mortgage Insurance Policy because of such fraud, dishonesty or
misrepresentation. In such circumstances, the issuer of the Mortgage Pool
Insurance Policy will be indemnified by the Seller for the amount of any loss
paid by the issuer of the Mortgage Pool Insurance Policy (each such amount, a
"Fraud Loss") under the terms of the Waiver Letter. The maximum aggregate amount
 
                                       27
<PAGE>   96
 
of Fraud Losses covered under the Waiver Letter and the period of time during
which such coverage will be provided will be specified in the related
Supplement.
 
SPECIAL HAZARD INSURANCE POLICIES
 
     If specified in the related Supplement, a separate Special Hazard Insurance
Policy will be obtained for the Mortgage Pool and will be issued by the insurer
(the "Special Hazard Insurer") named in such Supplement. Each Special Hazard
Insurance Policy will, subject to limitations described below, protect holders
of the related Certificates from (i) loss by reason of damage to Mortgaged
Properties caused by certain hazards (including earthquakes and, to a limited
extent, tidal waves and related water damage and such other hazards as are
specified in the related Supplement) not insured against under the standard form
of hazard insurance policy for the respective states in which the Mortgaged
Properties are located or under a flood insurance policy if the Mortgaged
Property is located in a federally designated flood area and (ii) loss caused by
reason of the application of the coinsurance clause contained in hazard
insurance policies. See "Servicing of Mortgage Loans -- Hazard Insurance"
herein. No Special Hazard Insurance Policy will cover losses occasioned by fraud
or conversion by the Trustee or Servicer, war, insurrection, civil war, certain
governmental action, errors in design, faulty workmanship or materials (except
under certain circumstances), nuclear or chemical reaction, flood (if the
Mortgaged Property is located in a federally designated flood area), nuclear or
chemical contamination and certain other risks. The amount of coverage under any
Special Hazard Insurance Policy will be specified in the related Supplement.
Each Special Hazard Insurance Policy will provide that no claim may be paid
unless hazard and, if applicable, flood insurance on the property securing the
Mortgage Loan have been kept in force and other protection and preservation
expenses have been paid.
 
     Subject to the foregoing limitations and unless otherwise specified in the
related Supplement, each Special Hazard Insurance Policy will provide that where
there has been damage to property securing a foreclosed Mortgage Loan (title to
which has been acquired by the insured) and to the extent such damage is not
covered by the hazard insurance policy or flood insurance policy, if any,
maintained by the Mortgagor or the Servicer, the Special Hazard Insurer will pay
the lesser of (i) the cost of repair or replacement of such property or (ii)
upon transfer of the property to the Special Hazard Insurer, the unpaid
principal balance of such Mortgage Loan at the time of acquisition of such
property by foreclosure or deed in lieu of foreclosure, plus accrued interest to
the date of claim settlement and certain expenses incurred by the Servicer with
respect to such property. If the unpaid principal balance of a Mortgage Loan
plus accrued interest and certain expenses is paid by the Special Hazard
Insurer, the amount of further coverage under the related Special Hazard
Insurance Policy will be reduced by such amount less any net proceeds from the
sale of the property. Any amount paid as the cost of repair of such property
will also reduce coverage by such amount. So long as a Mortgage Pool Insurance
Policy remains in effect, the payment by the Special Hazard Insurer of the cost
of repair or of the unpaid principal balance of the related Mortgage Loan plus
accrued interest and certain expenses will not affect the total insurance
proceeds paid to Certificateholders, but will affect the relative amounts of
coverage remaining under the related Special Hazard Insurance Policy and
Mortgage Pool Insurance Policy.
 
     To the extent specified in the Supplement, the Servicer may deposit cash,
an irrevocable letter of credit or any other instrument acceptable to each
nationally recognized rating agency rating the Certificates of the related
Series in a special trust account to provide protection in lieu of or in
addition to that provided by a Special Hazard Insurance Policy. The amount of
any Special Hazard Insurance Policy or of the deposit to the special trust
account in lieu thereof relating to such Certificates may be reduced so long as
any such reduction will not result in a downgrading of the rating of such
Certificates by any such rating agency.
 
BANKRUPTCY BONDS
 
     If specified in the related Supplement, a bankruptcy bond (the "Bankruptcy
Bond") to cover losses resulting from proceedings under the Bankruptcy Code with
respect to a Mortgage Loan will be issued by an insurer named in such
Supplement. Each Bankruptcy Bond will cover, to the extent specified in the
related Supplement, certain losses resulting from a reduction by a bankruptcy
court of scheduled payments of principal and interest on a Mortgage Loan or a
reduction by such court of the principal amount of a Mortgage
 
                                       28
<PAGE>   97
 
Loan and will cover certain unpaid interest on the amount of such a principal
reduction from the date of the filing of a bankruptcy petition. The required
amount of coverage under each Bankruptcy Bond will be set forth in the related
Supplement. Coverage under a Bankruptcy Bond may be cancelled or reduced by the
Servicer if such cancellation or reduction would not adversely affect the then
current rating or ratings of the related Certificates. See "Certain Legal
Aspects of the Mortgage Loans -- Anti-Deficiency Legislation and Other
Limitations on Sellers" herein.
 
     To the extent specified in the Supplement, the Servicer may deposit cash,
an irrevocable letter of credit or any other instrument acceptable to each
nationally recognized rating agency rating the Certificates of the related
Series in a special trust account to provide protection in lieu of or in
addition to that provided by a Bankruptcy Bond. The amount of any Bankruptcy
Bond or of the deposit to the special trust account in lieu thereof relating to
such Certificates may be reduced so long as any such reduction will not result
in a downgrading of the rating of such Certificates by any such rating agency.
 
RESERVE FUND
 
     If so specified in the related Supplement, credit support with respect to a
Series of Certificates may be provided by the establishment and maintenance with
the Trustee for such Series of Certificates, in trust, of one or more reserve
funds (the "Reserve Fund") for such Series. The related Supplement will specify
whether or not a Reserve Fund will be included in the Pool for such Series.
 
     The Reserve Fund for a Series will be funded (i) by the deposit therein of
cash, U.S. Treasury securities or instruments evidencing ownership of principal
or interest payments thereon, letters of credit, demand notes, certificates of
deposit or a combination thereof in the aggregate amount specified in the
related Supplement, (ii) by the deposit therein from time to time of certain
amounts, as specified in the related Supplement, to which Subordinate
Certificateholders, if any, would otherwise be entitled or (iii) in such other
manner as may be specified in the related Supplement.
 
     Any amounts on deposit in the Reserve Fund and the proceeds of any other
instrument deposited therein upon maturity will be held in cash or will be
invested in Eligible Investments. Any instrument deposited therein will name the
Trustee, in its capacity as trustee for Certificateholders, or such other entity
as is specified in the related Supplement, as beneficiary and will be issued by
an entity acceptable to each rating agency that rates the Certificates.
Additional information with respect to such instruments deposited in the Reserve
Funds will be set forth in the related Supplement.
 
     Any amounts so deposited and payments on instruments so deposited will be
available for withdrawal from the Reserve Fund for distribution to
Certificateholders for the purposes, in the manner and at the times specified in
the related Supplement.
 
CROSS SUPPORT
 
     If specified in the related Supplement, the beneficial ownership of
separate groups of assets included in a Pool may be evidenced by separate
classes of the related Series of Certificates. In such case, credit support may
be provided by a cross support feature which requires that distributions be made
with respect to Certificates evidencing a beneficial ownership interest in other
asset groups within the same Pool. The related Supplement for a Series that
includes a cross support feature will describe the manner and conditions for
applying such cross support feature.
 
OTHER INSURANCE, GUARANTIES, LETTERS OF CREDIT AND SIMILAR INSTRUMENTS OR
AGREEMENTS
 
     If specified in the related Supplement, a Pool may also include insurance,
guaranties, letters of credit or similar arrangements for the purpose of (i)
maintaining timely payments or providing additional protection against losses on
the assets included in such Pool, (ii) paying administrative expenses or (iii)
establishing a minimum reinvestment rate on the payments made in respect of such
assets or principal payment rate on such assets. Such arrangements may include
agreements under which Certificateholders are entitled to receive amounts
deposited in various accounts held by the Trustee upon the terms specified in
such Supplement.
 
                                       29
<PAGE>   98
 
                      MATURITY, PREPAYMENT CONSIDERATIONS
                   AND WEIGHTED AVERAGE LIFE OF CERTIFICATES
 
     The weighted average life of a Series of Certificates and the yield to
investors depend in part on the rate at which the Mortgage Loans or mortgage
loans underlying Mortgage Certificates are prepaid. Prepayments on mortgage
loans are commonly measured relative to a prepayment standard or model. The
prepayment model, if any, used with respect to a particular Series will be
identified and described in the related Supplement.
 
     The Supplement for a Series of Certificates may contain a table setting
forth percentages of the initial Certificate Balance of each class expected to
be outstanding after each of the dates shown in such table. Any such table will
be based upon a number of assumptions stated in such Supplement, including
assumptions that prepayments on the mortgage loans underlying the related
Mortgage Certificates or on the Mortgage Loans are made at rates corresponding
to various percentages of the prepayment model specified in the related
Supplement. It is unlikely, however, that the prepayment of the mortgage loans
underlying the Mortgage Certificates, or of the Mortgage Loans, underlying any
Series will conform to any of the percentages of the prepayment model described
in the table set forth in such Supplement.
 
     The rate of principal prepayments on pools of mortgage loans underlying the
Mortgage Certificates and Mortgage Loans is influenced by a variety of economic,
geographic, social and other factors. In general, however, if prevailing
interest rates fall significantly below the interest rates on such mortgage
loans or on the Mortgage Loans included in a Pool, such mortgage loans or
Mortgage Loans are likely to be the subject of higher principal prepayments than
if prevailing rates remain at or above the rates borne by such mortgage loans or
Mortgage Loans. Conversely, if prevailing interest rates rise appreciably above
the interest rates on such mortgage loans or on the Mortgage Rates borne by the
Mortgage Loans included in a Pool, such mortgage loans or Mortgage Loans are
likely to experience a lower prepayment rate than if prevailing rates remain at
or below the rates borne by such mortgage loans or Mortgage Rates. Other factors
affecting prepayment of mortgage loans and Mortgage Loans include changes in
mortgagors, housing needs, job transfers, unemployment, mortgagors' net equity
in the properties securing the mortgage loans and Mortgage Loans and servicing
decisions.
 
     Prepayments may also result from the enforcement of any "due-on-sale"
provisions contained in a Mortgage Note permitting the holder of the Mortgage
Note to demand immediate repayment of the outstanding balance of the Mortgage
Loan upon conveyance by the Mortgagor of the underlying Mortgaged Property. The
Servicer will agree that it or the applicable subservicer will enforce any
"due-on-sale" clause to the extent it has knowledge of the conveyance or
proposed conveyance of the underlying Mortgaged Property and reasonably believes
that it is entitled to do so under applicable law; provided, however, that the
Servicer or the subservicer will not take any action in relation to the
enforcement of any "due-on-sale" provision which would impair or threaten to
impair any recovery under any related Primary Mortgage Insurance Policy. Under
current law, such exercise is permitted for substantially all the mortgage loans
which contain such clauses. Acceleration is not permitted, however, for certain
types of transfers, including transfers upon the death of a joint tenant or
tenant by the entirety and the granting of a leasehold interest of three years
or less not containing an option to purchase.
 
                                  THE SPONSOR
 
     Tryon Mortgage Funding, Inc., a Delaware corporation (the "Sponsor"), was
organized on November 28, 1994 for the limited purpose of acquiring, owning and
transferring Mortgage Assets and selling interests therein or bonds secured
thereby. The Sponsor is a subsidiary of NationsBanc Mortgage Capital
Corporation, a Texas corporation. The Sponsor maintains its principal office at
NationsBank Corporate Center, Charlotte, North Carolina 28255. Its telephone
number is (704) 386-2400.
 
     Neither the Sponsor nor any of the Sponsor's affiliates will ensure or
guarantee distributions on the Certificates of any Series.
 
                                       30
<PAGE>   99
 
                                USE OF PROCEEDS
 
     Substantially all of the net proceeds to be received from the sale of each
Series of Certificates will be used by the Sponsor to either purchase the
Mortgage Assets related to that Series or to return to the Sponsor the amounts
previously used to effect such a purchase, the costs of carrying the Mortgage
Assets until sale of the Certificates and other expenses connected with pooling
the Mortgage Assets and issuing the Certificates. Any remaining proceeds will be
used for the general corporate purposes of the Sponsor.
 
                           MORTGAGE PURCHASE PROGRAM
 
     Set forth below is a description of aspects of the Sponsor's purchase
program for Mortgage Loans eligible for inclusion in a Pool. The related
Supplement will contain information regarding the origination of the Mortgage
Loans.
 
     The Sponsor will purchase Mortgage Loans either directly or indirectly from
the Servicer or from other approved Sellers, which may be affiliates of the
Sponsor or the Servicer. The Sponsor has approved (or will approve) individual
institutions as eligible Sellers by applying certain criteria, including the
Seller's depth of mortgage origination experience, servicing experience and
financial stability. From time to time, however, the Sponsor may purchase
Mortgage Loans from Sellers which, while not meeting the generally applicable
criteria, have been reviewed by the Sponsor and found to be acceptable as
Sellers of Mortgage Loans.
 
     Each Mortgage Loan purchased by the Sponsor must meet certain credit,
appraisal and underwriting standards, as described in the related Supplement.
 
     Underwriting standards are intended to evaluate the Mortgagor's credit
standing and repayment ability and the value and adequacy of the Mortgaged
Property as collateral. Underwriting standards are applied in a standard
procedure which complies with applicable federal and state laws and regulations.
 
     In determining the adequacy of the property as collateral, an appraisal is
generally made of each property considered for financing. The appraiser is
required to inspect the property and verify that it is in good condition and
that construction, if new, has been completed. The appraisal is based on the
appraiser's judgment of values, giving appropriate weight to both the market
value of comparable properties and the cost of replacing the property.
 
     Certain states where the Mortgaged Properties may be located are
"anti-deficiency" states where, in general, lenders providing credit on one- to
four-family properties must look solely to the property for repayment in the
event of foreclosure. Underwriting standards in all states (including
anti-deficiency states) require that the underwriting officers be satisfied that
the value of the property being financed, as indicated by the appraisal,
currently supports and is anticipated to support in the future the outstanding
loan balance, and provides sufficient value to mitigate the effects of adverse
shifts in real estate values.
 
     The related Supplement will provide a description of the underwriting
standards applied in originating the Mortgage Loans.
 
                      THE POOLING AND SERVICING AGREEMENT
 
     Set forth below is a summary of certain provisions of the Pooling Agreement
which are not described elsewhere in this Prospectus.
 
ASSIGNMENT OF MORTGAGE LOANS
 
     Assignment of Mortgage Loans.  At the time of issuance of each Series of
Certificates, the Sponsor will cause the Mortgage Loans comprising the related
Pool to be assigned to the Trustee together with all principal and interest on
the Mortgage Loans, except for principal and interest due on or before the
Cut-off Date. The Trustee will, concurrently with such assignment, authenticate
and deliver the Certificates to the Sponsor or its designated agent in exchange
for the Mortgage Loans and other assets, if any. Each Mortgage Loan will be
identified in a schedule appearing as an exhibit to the Pooling Agreement. Such
schedule will include
 
                                       31
<PAGE>   100
 
information as to the principal balance of each Mortgage Loan, the address of
the property, the Mortgage Rate and the maturity of each Mortgage Note.
 
     In addition, the Sponsor will, as to each Mortgage Loan, deliver to the
Trustee the Mortgage Note endorsed without recourse in blank or to the order of
the Trustee, an assignment to the Trustee of the Mortgage in form for recording
or filing as may be appropriate in the state of the Mortgaged Property, the
original recorded Mortgage with evidence of recording or filing indicated
thereon, or a copy of such Mortgage certified by the recording office or
certified by the related title insurance company, a copy of the title insurance
policy or other evidence of title, and evidence of any Primary Mortgage
Insurance Policy for such Mortgage Loan, if applicable. In certain instances
where documents respecting a Mortgage Loan may not be available prior to
execution of the Pooling Agreement, the Sponsor may deliver copies thereof and
deliver such documents to the Trustee promptly upon receipt.
 
     With respect to any Mortgage Loans that are Cooperative Loans, the Sponsor
will cause to be delivered to the Trustee the related original cooperative note
endorsed without recourse in blank or to the order of the Trustee, the original
security agreement, the proprietary lease or occupancy agreement, the
recognition agreement, an executed financing agreement and the relevant stock
certificate, related blank stock powers and any other document specified in the
related Supplement. The Sponsor will cause to be filed in the appropriate office
an assignment and a financing statement evidencing the Trustee's security
interest in each Cooperative Loan.
 
     The Trustee (or a custodian) will review the mortgage documents within a
specified number of days of receipt thereof in original form to ascertain that
all required documents have been properly executed and received. The Trustee
will hold such documents for each Series in trust for the benefit of holders of
the Certificates of such Series. Unless otherwise specified in the related
Supplement, if any document is found by the Trustee not to have been properly
executed or received or to be unrelated to the Mortgage Loans identified in the
Pooling Agreement, and such defect cannot be cured within the permitted time
period, the Seller will replace such Mortgage Loan with an Eligible Substitute
Mortgage Loan (as described in the related Supplement) or repurchase the related
Mortgage Loan from the Trustee within a specified number of days of receipt of
notice of the defect at a price generally equal to the principal balance
thereof, plus accrued and unpaid interest thereon at the applicable Mortgage
Rate less the applicable servicing fee (the "Net Mortgage Rate") to the first
day of the month following the month of repurchase. Upon receipt of the
repurchase price, in the case of a repurchase, the Trustee will reimburse any
unreimbursed Advances of principal and interest by the Servicer with respect to
such Mortgage Loan or unreimbursed payments under any form of credit support.
The remaining portion of such repurchase price will then be passed through to
holders of the Certificates as liquidation proceeds in accordance with the
procedures specified under "Description of Certificates -- Distributions"
herein. This substitution/repurchase obligation constitutes the sole remedy
available to Certificateholders or the Trustee for such a defect in a
constituent document.
 
     Any restrictions on such substitution or repurchase with respect to a
Series of Certificates will be set forth in the related Supplement.
 
     Unless otherwise specified in the related Supplement, assignments of the
Mortgage Loans to the Trustee will be recorded or filed in the appropriate
jurisdictions except in jurisdictions where, in the written opinion of local
counsel acceptable to the Sponsor, such filing or recording is not required to
protect the Trustee's interest in the Mortgage Loans against sale, further
assignment, satisfaction or discharge by the Sellers, the Servicer, the
subservicers or the Sponsor.
 
     Assignment of Agency Certificates.  The Sponsor will cause the Agency
Certificates to be registered in the name of the Trustee or its nominee. The
Trustee (or the custodian) will hold the Agency Certificates in the manner
described in the related Supplement. Each Agency Certificate will be identified
in a schedule appearing as an exhibit to the Pooling Agreement, which will
specify as to each Agency Certificate the original principal amount and
outstanding principal balance as of the Cut-off Date, the annual pass-through
rate (if any) and the maturity date.
 
                                       32
<PAGE>   101
 
     Assignment of Private Certificates.  The Sponsor will cause the Private
Certificates to be registered in the name of the Trustee. The Trustee (or the
custodian) will hold the Private Certificates in the manner described in the
related Supplement. The Trustee will not be in possession of or be assignee of
record of any underlying assets for a Private Certificate. Each Private
Certificate will be identified in a schedule appearing as an exhibit to the
related Pooling Agreement which will specify the original principal amount,
outstanding principal balance as of the Cut-off Date, annual pass-through rate
or interest rate and maturity date and certain other pertinent information for
each Private Certificate conveyed to the Trustee.
 
REPRESENTATIONS AND WARRANTIES
 
     Unless otherwise specified in the related Supplement, the Sponsor will not
make any representations and warranties regarding the Mortgage Loans, and its
assignment of the Mortgage Loans to the Trustee will be without recourse. As
further described below, the Seller will make certain representations and
warranties concerning the Mortgage Loans in the related Pooling Agreement and
under certain circumstances may be required to repurchase or substitute a
Mortgage Loan as a result of a breach of any such representation or warranty. In
addition, pursuant to the related Pooling Agreement the Sponsor will assign to
the Trustee its rights with respect to representations and warranties made by
the Seller in the agreement pursuant to which the Mortgage Loans are sold to the
Sponsor (each, a "Seller's Agreement").
 
     In the Pooling Agreement for each Series of Certificates backed in whole or
in part by Mortgage Loans, the Seller will represent and warrant to the Trustee,
unless otherwise specified in the related Supplement, among other things, that:
(i) the information set forth in the schedule of Mortgage Loans is true and
correct in all material respects; (ii) at the time of transfer the Seller had
good title to the Mortgage Loans and the Mortgage Notes were subject to no
offsets, defenses or counterclaims, except to the extent that the buydown
agreement for a Buydown Loan forgives certain indebtedness of a Mortgagor; (iii)
as of the Cut-off Date, no Mortgage Loan was more than 30 days delinquent; (iv)
a Seller's title policy (or other satisfactory evidence of title) was issued on
the date of the origination of each Mortgage Loan and each such policy or other
evidence of title is valid and remains in full force and effect; (v) if a
Primary Mortgage Insurance Policy is required with respect to such Mortgage
Loan, such policy is valid and remains in full force and effect as of the
Closing Date; (vi) as of the Closing Date, each Mortgage Loan is secured by a
first lien Mortgage or by a Land Sale Contract on the related Mortgaged Property
free and clear of all liens, claims and encumbrances, other than the Land Sale
Contract, if applicable (subject only to (a) liens for current real property
taxes and special assessments, (b) covenants, conditions and restrictions,
rights of way, easements and other matters of public record as of the date of
recording of such Mortgage, such exceptions appearing of record being acceptable
to mortgage lending institutions generally or specifically reflected in the
mortgage originator's appraisal, and (c) other matters to which like properties
are commonly subject which do not materially interfere with the benefits of the
security intended to be provided by the Mortgage); (vii) as of the Closing Date,
each Mortgaged Property is free of damage and is in good repair; (viii) as of
the time each Mortgage Loan was originated, the Mortgage Loan complied with all
applicable state and federal laws, including usury, equal credit opportunity,
disclosure and recording laws; and (ix) as of the Closing Date, there are no
delinquent tax or assessment liens against any Mortgaged Property.
 
     In the event of the discovery by the Seller of a breach of any of its
representations or warranties which materially and adversely affects the
interest of Certificateholders in the related Mortgage Loan, or the receipt of
notice thereof from the Trustee, the Seller will, with respect to a breach of
its representations or warranties, cure the breach within the time permitted by
the related Pooling Agreement or substitute a substantially similar substitute
mortgage loan for such Mortgage Loan or repurchase the related Mortgage Loan, or
any Mortgaged Property acquired in respect thereof, on the terms set forth above
under "-- Assignment of Mortgage Loans" and in the related Supplement. The
proceeds of any such repurchase will be passed through to Certificateholders as
liquidation proceeds. This substitution/repurchase obligation constitutes the
sole remedy available to Certificateholders and the Trustee for any such breach.

SERVICING
 
     The Servicer will be responsible for servicing and administering the
Mortgage Loans and will agree to perform diligently all services and duties
customary to the servicing by prudent mortgage lending institutions or mortgages
of the same type as the Mortgage Loans in those jurisdictions where the related
Mortgaged Properties are located. The Servicer may enter into a subservicing
agreement with a subservicer to perform, as an independent contractor, certain
servicing functions for the Servicer subject to its supervision. A subservicing
agreement will not contain any terms or conditions that are inconsistent with
the related Pooling Agreement. The subservicer will receive a fee for such
services which will be paid by the Servicer out of the Servicing Fee. The
Servicer will have the right to remove the subservicer of any Mortgage Loan at
any time for cause and at any other time upon the giving of the required notice.
In such event, the Servicer would continue to be responsible for servicing such
Mortgage Loan and may designate a replacement subservicer (which may include an
affiliate of the Sponsor or the Servicer).
 
     The Servicer is required to maintain a fidelity bond and errors and
omissions policy or their equivalent with respect to officers and employees
which provide coverage against losses which may be sustained as a result of an
officer's or employee's misappropriation of funds or errors and omissions in
failing to maintain insurance, subject to certain limitations as to amount of
coverage, deductible amounts, conditions, exclusions and exceptions in the form
and amount specified in the Pooling Agreement.
 
PAYMENTS ON MORTGAGE LOANS
 
     The Servicer will establish and maintain or cause to be established and
maintained with respect to the related Pool a Certificate Account or accounts
for the collection of payments on the related Mortgage Loans, which must be an
Eligible Account. An "Eligible Account" is an account or accounts which is
either (i) maintained with a depository institution the obligations of which
(or, in the case of a depository institution that is the principal subsidiary of
a holding company, the obligations of such holding company) are rated in one of
the two highest short-term rating categories by the Rating Agency that rated one
or more classes of the related Series of Certificates, (ii) an account or
accounts the deposits in which are fully insured by the FDIC, (iii) an account
or accounts the deposits in which are insured by the FDIC to the limits
established by the FDIC and the uninsured deposits in which are otherwise
secured such that, as evidenced by an opinion of counsel, Certificateholders
have a claim with respect to the funds in such account or accounts, or a
perfected first-priority security interest against any collateral securing such
funds, that is superior to the claims of any other depositors or general
creditors of the depository institution with which such account or accounts are
maintained or (iv) an account or accounts otherwise acceptable to such Rating
Agency. The collateral eligible to secure amounts in the Certificate Account is
limited to Eligible Investments consisting of United States government
securities and other high-quality investments. A Certificate Account may be
maintained as an interest-bearing account, or the funds held therein may be
invested pending each succeeding Distribution Date in Eligible Investments. The
Servicer or its designee will be entitled to receive any such interest or other
income earned on funds in the Certificate Account as additional compensation and
will be obligated to deposit in the Certificate Account the amount of any loss
immediately as realized. The Certificate Account may be maintained with the
Servicer or the Seller or with a depository institution that is an affiliate of
the Servicer or the Sponsor, provided it is an Eligible Account.
 
     Unless otherwise specified in the related Supplement, the Servicer will
deposit in the Certificate Account for each Pool on a daily basis, to the extent
applicable, the following payments and collections received by or on behalf of
it subsequent to the Cut-off Date (other than payments due on or before the
Cut-off Date):
 
          (i) All payments on account of principal and interest (which, at its
     option, may be net of the servicing fee), including principal prepayments
     (in whole or in part);
 
          (ii) All amounts received by foreclosure or otherwise in connection
     with the liquidation of defaulted Mortgage Loans, net of expenses incurred
     in connection with such liquidation;
 
                                       34
<PAGE>   103
 
          (iii) All proceeds received under any Primary Mortgage Insurance
     Policy or title, hazard or other insurance policy covering any Mortgage
     Loan, other than proceeds to be applied to the restoration or repair of the
     related Mortgaged Property;
 
          (iv) All advances as described herein under "Advances";
 
          (v) All proceeds of any Mortgage Loans or property acquired in respect
     thereof repurchased as described herein under "-- Assignment of Mortgage
     Loans" and "-- Representations and Warranties";
 
          (vi) Any Buydown Funds (and, if applicable, investment earnings
     thereon) required to be deposited in the Certificate Account as described
     below;
 
          (vii) All payments required to be deposited in the Certificate Account
     with respect to any deductible clause in any blanket insurance policy
     described under "-- Hazard Insurance" herein;
 
          (viii) Any amount required to be deposited by the Servicer in
     connection with losses realized on investments for the benefit of the
     Servicer of funds held in the Certificate Account; and
 
          (ix) All other amounts required to be deposited in the Certificate
     Account.
 
     Under the Pooling Agreement for each Series, the Servicer will be
authorized to make the following withdrawals from the Certificate Account:
 
          (i) To clear and terminate the Certificate Account upon liquidation of
     all Mortgage Loans or other termination of the Pool;
 
          (ii) To reimburse any provider of credit support for payments under
     such credit support from amounts received as late payments on related
     Mortgage Loans or from related insurance or liquidation proceeds;
 
          (iii) To reimburse the Servicer for Advances of principal and interest
     from amounts received as late payments on related Mortgage Loans, from
     related insurance or liquidation proceeds or from other amounts received
     with respect to such Mortgage Loans;
 
          (iv) To reimburse the Servicer from related insurance or liquidation
     proceeds for amounts expended by the Servicer in connection with the
     restoration of property damaged by an uninsured cause or the liquidation of
     a Mortgage Loan;
 
          (v) To pay to the Servicer its Servicing Fee and to the Trustee its
     fee;
 
          (vi) To reimburse the Servicer for Advances which the Servicer has
     determined to be otherwise nonrecoverable; and
 
          (vii) To pay any expenses which were incurred and are reimbursable
     pursuant to the Pooling Agreement.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
     The Servicer will agree to proceed diligently to collect all payments
called for under the Mortgage Notes. Consistent with the above, the Servicer
may, in its discretion, (i) waive any prepayment charge, assumption fee, late
payment charge or any other charge in connection with the prepayment of a
Mortgage Loan and (ii) arrange with a Mortgagor a plan of relief, other than a
modification or extension of the Mortgage, when appropriate rather than
recommending liquidation. Such arrangement will be made only upon determining
that the coverage of such Mortgage Loan by any Primary Mortgage Insurance Policy
will not be affected. In the event of any such arrangement, but only to the
extent of the amount of any credit support, the provider of such credit support
will honor requests for payment or otherwise distribute funds with respect to
such Mortgage Loan during the scheduled period in accordance with the
amortization schedule thereof and without regard to the temporary modification
thereof. In addition, in the event of any such arrangement, the Servicer's
obligation to make Advances on the related Mortgage Loan shall continue during
the scheduled period.
 
                                       35
<PAGE>   104
 
     Under the Pooling Agreement, the Servicer will be required to enforce
"due-on-sale" clauses with respect to the Mortgage Loans to the extent
contemplated by the terms of the Mortgage Loans and permitted by applicable law.
Where an assumption of, or substitution of liability with respect to, a Mortgage
Loan is required by law, upon receipt of assurance that the Primary Mortgage
Insurance Policy covering such Mortgage Loan will not be affected, the Servicer
may permit the assumption of a Mortgage Loan, pursuant to which the Mortgagor
would remain liable on the Mortgage Note, or a substitution of liability with
respect to such Mortgage Loan, pursuant to which the new Mortgagor would be
substituted for the original Mortgagor as being liable on the Mortgage Note. Any
fees collected for entering into an assumption or substitution of liability
agreement may be retained by the Servicer as additional servicing compensation.
In connection with any assumption or substitution, the Mortgage Rate borne by
the related Mortgage Note may not be changed.
 
     The Pooling Agreement may require the Servicer to establish and maintain
one or more escrow accounts into which Mortgagors deposit amounts sufficient to
pay taxes, assessments, hazard insurance premiums or comparable items.
Withdrawals from the escrow accounts maintained for Mortgagors may be made to
effect timely payment of taxes, assessments and hazard insurance premiums or
comparable items, to reimburse the Servicer out of related assessments for
maintaining hazard insurance, to refund to Mortgagors amounts determined to be
overages, to remit to Mortgagors, if required, interest earned, if any, on
balances in any of the escrow accounts, to repair or otherwise protect the
Mortgaged Property and to clear and terminate any of the escrow accounts. The
Servicer will be solely responsible for administration of the escrow accounts
and will be expected to make advances to such account when a deficiency exists
therein.
 
HAZARD INSURANCE
 
     Unless otherwise specified in the related Supplement, under the Pooling
Agreement, the Servicer will be required to maintain for each Mortgage Loan a
hazard insurance policy providing coverage against loss by fire and other
hazards which are covered under the standard extended coverage endorsement
customary in the state in which the property is located. Such coverage will be
in an amount at least equal to the lesser of the original principal balance on
such Mortgage Loan and the replacement cost of the Mortgaged Property. As set
forth above, all amounts collected by the Servicer under any hazard policy
(except for amounts to be applied to the restoration or repair of the Mortgaged
Property or released to the Mortgagor in accordance with the Servicer's normal
servicing procedures) will be deposited in the Certificate Account. In the event
that the Servicer maintains a blanket policy insuring against hazard losses on
all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its
obligation relating to the maintenance of hazard insurance. Such blanket policy
may contain a deductible clause, in which case the Servicer will deposit in the
Certificate Account all sums which would have been deposited therein but for
such clause.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements on the property by fire,
lightening, explosion, smoke, windstorm and hail, and riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. Although the policies relating to the Mortgage Loans will be
underwritten by different insurers under different state laws in accordance with
different applicable state forms and therefore will not contain identical terms
and conditions, the basic terms thereof are dictated by respective state laws,
and most such policies typically do not cover (among other things) any physical
damage resulting from the following: war, revolution, governmental actions,
floods and other water-related causes, earth movement (including earthquakes,
landslides and mud flows), nuclear reactions, wet or dry rot, vermin, rodents,
insects or domestic animals, theft and, in certain cases, vandalism. If,
however, any Mortgaged Property is located in an area identified by the Flood
Emergency Management Agency as having special flood hazards and flood insurance
has been made available, if required by applicable law, the Servicer will cause
to be maintained with a generally acceptable insurance carrier a flood insurance
policy meeting the requirements of the current guidelines of the Federal
Insurance Administration. Such flood insurance policy will provide coverage in
an amount not less than the least of (i) the original principal balance of the
Mortgage Loan, (ii) the insurable value of the Mortgaged Property or (iii) the
maximum amount of insurance available under the Flood Disaster Protection Act of
1973, as amended.
 
                                       36
<PAGE>   105
 
     The hazard insurance policies covering the Mortgaged Properties typically
contain a clause which, in effect, requires the insured at all times to carry
insurance of a specified percentage (generally 80% to 90%) of the full
replacement value of the improvements on the property in order to recover the
full amount of any partial loss. If the insured's coverage falls below this
specified percentage, such clause provides that the insurer's liability in the
event of partial loss does not exceed the larger of (i) the replacement cost of
the improvements less physical depreciation, and (ii) such proportion of the
loss as the amount of insurance carried bears to the specified percentage of the
full replacement cost of such improvements. Since residential properties
historically have appreciated in value over time, in the event of partial loss,
hazard insurance proceeds may be insufficient to restore fully the damaged
property.
 
PRIMARY MORTGAGE INSURANCE
 
     If specified in the related Supplement, a Mortgage Loan secured by a
Mortgaged Property having an LTV in excess of 80% will have a policy (a "Primary
Mortgage Insurance Policy") insuring against default all or a specified portion
of the principal amount thereof in excess of such percentage of the value of the
Mortgaged Property, as specified in the related Supplement.
 
     Evidence of each Primary Mortgage Insurance Policy will be provided to the
Trustee simultaneously with the transfer to the Trustee of the related Mortgage
Loan. The Servicer, on behalf of itself, the Trustee and Certificateholders, is
required to present claims to the insurer under any Primary Mortgage Insurance
Policy and to take such reasonable steps as are necessary to permit recovery
thereunder with respect to defaulted Mortgage Loans. Amounts collected by the
Servicer on behalf of the Servicer, the Trustee and Certificateholders shall be
deposited in the Certificate Account for distribution as set forth above. The
Servicer will not cancel or refuse to renew any Primary Mortgage Insurance
Policy required to be kept in force by the Pooling Agreement.
 
MAINTENANCE OF INSURANCE POLICIES; CLAIMS THEREUNDER AND OTHER REALIZATION UPON
DEFAULTED MORTGAGE LOANS
 
     The Servicer will exercise its best reasonable efforts to keep each Primary
Mortgage Insurance Policy (if any) in full force and effect at least until the
outstanding principal balance of the related Mortgage Note is equal to the
percentage of the appraised value of the Mortgaged Property specified in the
related Supplement. The Servicer has agreed (or will agree) to pay the premium
for each Primary Mortgage Insurance Policy on a timely basis in the event that
the Mortgagor does not make such payments.
 
     The Servicer, on behalf of the Trustee and Certificateholders, will present
claims to the insurer under any applicable Primary Mortgage Insurance Policy and
will take such reasonable steps as are necessary to permit recovery under such
insurance policies respecting defaulted Mortgage Loans. If any property securing
a defaulted Mortgage Loan is damaged and proceeds, if any, from the related
hazard insurance policy are insufficient to restore the damaged property to a
condition sufficient to permit recovery under any applicable Primary Mortgage
Insurance Policy, the Servicer will not be required to expend its own funds to
restore the damaged property unless the Servicer determines (i) that such
restoration will increase the proceeds to Certificateholders upon liquidation of
the Mortgage Loan after reimbursement of the Servicer for its expenses and (ii)
that such expenses will be recoverable to it through liquidation proceeds.
 
     Regardless of whether recovery under any Primary Mortgage Insurance Policy
is available or any further amount is payable under the credit support for a
Series of Certificates, the Servicer is nevertheless obligated to follow such
normal practices and procedures as it deems necessary or advisable to realize
upon the defaulted Mortgage Loan. If at any time no further amount is payable
under the credit support for a Series of Certificates, and if the proceeds of
any liquidation of the property securing the defaulted Mortgage Loan are less
than the principal balance of the defaulted Mortgage Loans plus interest accrued
thereon, Certificateholders will realize a loss in the amount of such difference
plus the aggregate of unreimbursed advances of the Servicer with respect to such
Mortgage Loan and expenses incurred by the Servicer in connection with such
proceedings and which are reimbursable under the Pooling Agreement.
 
                                       37
<PAGE>   106
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Servicer's primary compensation for its activities as Servicer will
come from the payment to it, with respect to each interest payment on a Mortgage
Loan, of the amount specified in the related Supplement (the "Servicing Fee").
As principal payments are made on the Mortgage Loans, the portion of each
monthly payment which represents interest will decline, and thus servicing
compensation to the Servicer will decrease as the Mortgage Loans amortize.
Prepayments and liquidations of Mortgage Loans prior to maturity will also cause
servicing compensation to the Servicer to decrease.
 
     In addition, the Servicer will be entitled to retain all prepayment fees,
assumption fees and late payment charges, to the extent collected from
Mortgagors.
 
     The Servicer will pay all expenses incurred in connection with its
activities as Servicer (subject to limited reimbursement), including payment of
the fees and disbursements of the Trustee, payment of any fees for providing
credit support and payment of expenses incurred in connection with distributions
and reports to Certificateholders of each Series.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Pooling Agreement relating to a Series of Certificates backed in whole
or in part by Mortgage Loans will provide that the Servicer at its expense shall
cause a firm of independent public accountants to furnish a report annually to
the Trustee to the effect that such firm has verified the mathematical accuracy
of certain reports furnished by the Servicer to the Trustee relating to the
Mortgage Loans based on information obtained from subservicers and that such
review has disclosed no items of noncompliance with the provisions of such
Pooling Agreement which, in the opinion of such firm, are material, except for
such items of noncompliance as shall be set forth in such report.
 
     Each Pooling Agreement will provide for delivery to the Trustee of an
annual statement signed by an officer of the Servicer to the effect that the
Servicer has fulfilled its obligations under the Pooling Agreement throughout
the preceding year.
 
CERTAIN MATTERS REGARDING THE SPONSOR, THE SELLER AND THE SERVICER
 
     The Pooling Agreement for each Series of Certificates backed in whole or in
part by Mortgage Loans will provide that the Servicer may not resign from its
obligations and duties as Servicer thereunder, except upon (a) appointment of a
successor servicer and receipt by the Trustee of a letter from the Rating Agency
that such resignation and appointment will not result in the downgrading of the
Certificates or (b) determination that its duties thereunder are no longer
permissible under applicable law. No such resignation under (b) above will
become effective until the Trustee or a successor has assumed the Servicer's
obligations and duties under such Pooling Agreement.
 
     The Pooling Agreement for each such Series will also provide that neither
the Sponsor, the Servicer nor the Seller, nor any directors, officers, employees
or agents of any of them (collectively, the "Indemnified Parties") will be under
any liability to the Pool or Certificateholders or the Trustee, any subservicer
or others for any action taken (or not taken) by any Indemnified Party, any
subservicer or the Trustee in good faith pursuant to the Pooling Agreement, or
for errors in judgment; provided, however, that neither the Sponsor, the Seller,
the Servicer nor any such person will be protected against any liability which
would otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties thereunder. The Pooling Agreement will further provide
that each Indemnified Party is entitled to indemnification by the Pool and will
be held harmless against any loss, liability or expense incurred in connection
with any legal action relating to the Pooling Agreement or the Certificates for
such Series, other than any loss, liability or expense related to any specific
Mortgage Loan or Mortgage Loans (except any such loss, liability or expense
otherwise reimbursable pursuant to the Pooling Agreement) and any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
gross negligence in the performance of such Indemnified Party's duties
thereunder or by reason of reckless disregard by such indemnified Party of its
obligations and duties thereunder. In addition, the Pooling Agreement will
 
                                       38
<PAGE>   107
 
provide that neither the Sponsor, the Seller nor the Servicer is under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to, in the case of the Sponsor, the Seller or the Servicer, its
duties under the Pooling Agreement and which in its opinion may involve it in
any expense or liability. Each of the Sponsor, the Seller and the Servicer may,
however, in its discretion, undertake any such action which it may deem
necessary or desirable with respect to the Pooling Agreement and the rights and
duties of the parties thereto and the interests of Certificateholders
thereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom will be expenses, costs and liabilities of the
Pool and the Sponsor, the Seller and the Servicer will be entitled to be
reimbursed therefor out of the Certificate Account.
 
EVENTS OF DEFAULT
 
     Events of default by the Servicer under the Pooling Agreement for each
Series of Certificates evidencing an interest in Mortgage Loans will consist of
(i) any failure by the Servicer to make or cause to be made any required payment
pursuant to the terms of the Agreement (other than an advance required
thereunder) which continues unremedied for five days; (ii) any failure by the
Servicer duly to observe or perform in any material respects any other of its
covenants or agreements in the Certificates or in such Pooling Agreement which
continues unremedied for 30 days after the giving of written notice of such
failure to the Servicer by the Trustee, or to the Servicer and the Trustee by
holders of Certificates evidencing not less than 25% of the aggregate voting
rights of the Certificates for such Series; and (iii) certain events of
insolvency, readjustment of debt, marshalling of assets and liabilities or
similar proceedings and certain actions by the Servicer indicating insolvency,
reorganization or inability to pay its obligations.
 
RIGHTS UPON EVENT OF DEFAULT
 
     As long as an Event of Default under the Pooling Agreement for any Series
of Certificates evidencing an interest in Mortgage Loans remains unremedied, the
Trustee or holders of Certificates evidencing not less than 50% of the aggregate
voting rights of the Certificates for such Series may terminate all of the
rights and obligations of the Servicer under such Pooling Agreement, whereupon
the Trustee will succeed to all the responsibilities, duties and liabilities of
the Servicer under such Pooling Agreement and will be entitled to similar
compensation arrangements and limitations on liability. In the event that the
Trustee is unwilling or unable so to act, it may appoint or petition a court of
competent jurisdiction for the appointment of a housing and home finance
institution with a net worth of at least $10,000,000 to act as successor
Servicer under such Pooling Agreement. Pending any such appointment, the Trustee
is obligated to act in such capacity. The Trustee and such successor may agree
upon the servicing compensation to be paid, which in no event may be greater
than the compensation to the Servicer under such Pooling Agreement.
 
ENFORCEMENT
 
     No Certificateholder of any Series will have any right under the applicable
Pooling Agreement to institute any proceeding with respect to such Pooling
Agreement unless such Certificateholder previously has given to the Trustee
written notice of default and unless holders of Certificates evidencing not less
than 25% of the aggregate voting rights of the Certificates for such Series have
made written requests to the Trustee to institute such proceeding in its own
name as Trustee thereunder and have offered and provided to the Trustee
reasonable indemnity and the Trustee for 60 days has neglected or refused to
institute any such proceeding. However, the Trustee is under no obligation to
exercise any of the trusts or powers vested in it by the Pooling Agreement for
any Series or to make any investigation of matters arising thereunder or to
institute, conduct or defend any litigation thereunder or in relation thereto at
the request, order or direction of any Certificateholders, unless such
Certificateholders have offered and provided to the Trustee reasonable security
or indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.
 
AMENDMENT
 
     The Pooling Agreement for each Series may be amended by the Sponsor, the
Seller, the Servicer and the Trustee, without notice to or the consent of any
Certificateholder, (i) to cure any ambiguity, (ii) to correct a defective
provision or correct or supplement any provision therein that may be
inconsistent with any other
 
                                       39
<PAGE>   108
 
provision therein, (iii) to make any other provisions with respect to matters or
questions arising under such Pooling Agreement which are not inconsistent with
the provisions of such Pooling Agreement, or (iv) to comply with any
requirements imposed by the Code or any regulation thereunder; provided,
however, that no such amendments (except those pursuant to clause (iv)) will
adversely affect in any material respect the interests of any Certificateholder
of that Series. Any such amendment except pursuant to clause (iv) of the
preceding sentence should be deemed not to adversely affect in any material
respect the interests of any Certificateholders if the Trustee receives written
confirmation from the Rating Agency rating such Certificates that such amendment
will not cause such Rating Agency to reduce the then current rating thereof. The
Pooling Agreement for each Series may also be amended by the Sponsor, the
Seller, the Servicer and the Trustee with the consent of holders of Certificates
evidencing not less than 66 2/3% of the aggregate voting rights of each class of
Certificates for such Series affected thereby for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
such Pooling Agreement or of modifying in any manner the rights of holders of
Certificates of that Series; 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 in respect to any such
Certificate without the consent of the holder of such Certificate or (ii) with
respect to any Series of Certificates, reduce the aforesaid percentages of
Certificates the holders of which are required to consent to any such amendment
without the consent of the holders of all Certificates of such Series then
outstanding.
 
LIST OF CERTIFICATEHOLDERS
 
     In the event the Trustee is not the Certificate Registrar for a Series of
Certificates, upon written request of the Trustee, the Certificate Registrar
will provide to the Trustee within 30 days after the receipt of such request a
list of the names and addresses of all Certificateholders of record of a
particular Series as of the most recent Record Date for payment of distributions
to Certificateholders of that Series. Upon written request of three or more
Certificateholders of record of a Series of Certificates, for purposes of
communicating with other Certificateholders with respect to their rights under
the Pooling Agreement for such Series, the Trustee will afford such
Certificateholders access during business hours to the most recent list of
Certificateholders of that Series held by the Trustee.
 
TERMINATION; REPURCHASE OF MORTGAGE LOANS AND MORTGAGE CERTIFICATES
 
     The obligations of the Sponsor, the Seller, the Servicer and the Trustee
created by the Pooling Agreement will terminate upon the earlier of (i) the
maturity or other liquidation of the last Mortgage Loan or Mortgage Certificate
subject thereto and the disposition of all property acquired upon foreclosure of
any Mortgage Loan and (ii) the payment to Certificateholders of that Series of
all amounts required to be paid to them pursuant to such Pooling Agreement. In
no event, however, will the Trust created by any Pooling Agreement continue
beyond the expiration of 21 years from the death of the survivor of the persons
named in such Pooling Agreement.
 
     The Pooling Agreement for each Series may permit the Servicer to repurchase
all remaining Mortgage Loans and property acquired in respect thereof at a
purchase price equal to no less than the Certificate Balance of the
Certificates, together with accrued and unpaid interest at the applicable
Certificate Rate from the last date to which interest has been paid to the first
day of the month in which such repurchase occurs (subject to reduction as
provided in the Pooling Agreement, if the purchase price is based in part on the
appraised value of any REO Property and such appraised value is less than the
principal balance of the related Mortgage Loan at the time of foreclosure). The
exercise of such right will effect early retirement of the Certificates of such
Series, but the Servicer's right so to repurchase is subject to the aggregate
principal balances of the Mortgage Loans at the time of repurchase being less
than the percentage of the aggregate initial principal amount of all
Certificates of such Series at the Cut-off Date specified in the related
Supplement.
 
     The holder or holders of the Residual Certificates of a REMIC Series may
have the option to repurchase the remaining Mortgage Assets included in the Pool
relating to such Series. Any such option will be exercisable, in the case of
holders of Residual Certificates, at such time and under the circumstances
specified
 
                                       40

in the related Supplement provided that the Trustee has received an opinion of
counsel that the repurchase and related distributions to Certificateholders will
be part of a "qualified liquidation" as defined in Code Section 860F(a)(4)(A),
will not cause the Pool to be treated as an association taxable as a corporation
and will not otherwise subject the REMIC Pool to tax.
 
     For each Series, the holder or holders of the Residual Certificates or the
Trustee, as the case may be, will give written notice of termination of the
Pooling Agreement to each Certificateholder, and the final distribution will be
made only upon surrender and cancellation of the Certificates at an office or
agency of the Trustee specified in the notice of termination.
 
THE TRUSTEE
 
     The identity of the commercial bank, savings and loan association or trust
company named as Trustee for each Series of Certificates will be set forth in
the related Supplement. The Trustee may have normal banking relationships with
the Sponsor, the Seller, the Servicer and/or the subservicers.
 
                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
MORTGAGES
 
     The Mortgages will be either deeds of trust, security deeds or mortgages,
depending upon the prevailing practice in the state in which the Mortgaged
Property is located. A mortgage creates a lien upon the real property encumbered
by the mortgage. It is not prior to the lien for real estate taxes and
assessments. Priority between mortgages depends on their terms and generally on
the order of recording in a county or municipal office. There are two parties to
a mortgage: the mortgagor, who is the borrower and homeowner, and the mortgagee
who is the lender. Under the mortgage instrument, the mortgagor delivers to the
mortgagee a note or bond and the mortgage. Although a deed of trust is similar
to a mortgage, a deed of trust formally has three parties: the
borrower-homeowner, called the trustor (similar to a mortgagor), a lender
(similar to a mortgagee), called the beneficiary, and a third-party grantee,
called the trustee. Under a deed of trust, the trustor grants the property,
irrevocably until the debt is paid, in trust, generally with a power of sale, to
the trustee to secure payment of the obligation. The trustee's authority under a
deed of trust and the mortgagee's authority under a mortgage are governed by
law, by the express provisions of the deed of trust or mortgage and, in some
cases, by the directions of the beneficiary.
 
COOPERATIVES
 
     "Cooperative Loans" are loans with respect to a residential property
evidenced by a promissory note secured by a security interest in shares issued
by a cooperative corporation. The cooperative is owned by tenant-stockholders
who, through ownership of stock, shares or membership certificates in the
corporation, receive proprietary leases or occupancy agreements which confer
exclusive rights to occupy specific units. Generally, a tenant-stockholder of a
cooperative must make a monthly payment to the cooperative representing such
tenant-stockholder's pro rata share of the cooperative's payments for its
blanket mortgage, real property taxes, maintenance expenses and other capital or
ordinary expenses. An ownership interest in a cooperative and accompanying
occupancy rights are financed through a cooperative share loan evidenced by a
promissory note and secured by a security interest in the occupancy agreement or
proprietary lease and in the related cooperative shares. The lender takes
possession of the share certificate and a counterpart of the proprietary lease
or occupancy agreement and a financing statement covering the proprietary lease
or occupancy agreement and the cooperative shares is filed in the appropriate
state and local offices to perfect the lender's interest in its collateral.
Subject to the limitations discussed below, upon default of the tenant-
stockholder, the lender may sue for judgment on the promissory note, dispose of
the collateral at a public or private sale or otherwise proceed against the
collateral or tenant-stockholder as an individual as provided in the security
agreement covering the assignment of the proprietary lease or occupancy
agreement and the pledge of corporate shares. See "Foreclosure -- Shares of
Cooperatives" below.
 
                                       41
<PAGE>   110
 
     The private, cooperative apartment corporation owns all the real property
that comprises the project, including the land, separate dwelling units and all
common areas. The cooperative is directly responsible for project management
and, in most cases, payment of real estate taxes and hazard and liability
insurance. If there is a blanket mortgage on the cooperative apartment building
and/or underlying land, as is generally the case, the cooperative, as project
mortgagor, is also responsible for meeting these mortgage obligations. A blanket
mortgage is ordinarily entered into by the cooperative in connection with the
construction, rehabilitation or purchase of the cooperative's apartment
building. The interests of the occupant under proprietary leases or occupancy
agreements to which that cooperative is a party are generally subordinate to the
interests of the holder of the blanket mortgage on that building and/or
underlying land. If the cooperative is unable to meet the payment obligations
arising under its blanket mortgage note, the mortgagee holding the blanket
mortgage could foreclose on that mortgage and terminate all subordinate
proprietary leases and occupancy agreements. Also, the blanket mortgage note
given by the cooperative may not fully amortize, with a significant portion of
principal being due in one lump sum at final maturity. The inability of the
cooperative to refinance this mortgage and its consequent inability to make such
final payment could lead to foreclosure by the mortgagee providing the
financing. A foreclosure in either event by the holder of the blanket mortgage
could eliminate or significantly diminish the value of any collateral held by
the lender who financed the purchase by an individual tenant-stockholder of
cooperative shares or, in the case of a Pool, the collateral securing the
Cooperative Loans.
 
LAND SALE CONTRACTS
 
     Under an installment land sale contract for the sale of real estate (a
"land sale contract") the contract seller (hereinafter referred to as the
"lender") retains legal title to the property and enters into an agreement with
the contract purchaser (hereinafter referred to as the "borrower") for the
payment of the purchase price, plus interest, over the term of the land sale
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 land
sale contract, the borrower is 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 land sale contracts
generally provide that upon default by the borrower, the borrower loses his or
her right to occupy the property, the entire indebtedness is accelerated, and
the buyer's equitable interest in the property is forfeited. The lender in such
a situation does not have to foreclose in order to obtain title to the property,
although in some cases a quiet title action is in order if the borrower has
filed the land sale 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 a land sale contract, the courts will
permit ejectment of the buyer and a forfeiture of his or her interest in the
property. However, most state legislatures have enacted provisions by analogy to
mortgage law protecting borrowers under land sale contracts from the harsh
consequences of forfeiture. Under such statutes, a judicial or nonjudicial
foreclosure may be required, 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-foreclosure statutory redemption right.
In other states, courts in equity may permit a borrower with significant
investment in the property under a land sale contract for the sale of real
estate to share 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 a land sale 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.
 
FORECLOSURE
 
     Mortgages.  Foreclosure of a mortgage is generally accomplished by judicial
action. The action is initiated by the service of legal pleadings upon all
parties having an interest in the real property. Delays in
 
                                       42
<PAGE>   111
 
completion of the foreclosure may occasionally result from difficulties in
locating necessary parties defendant. Judicial foreclosure proceedings are
generally not contested by any of the parties defendant. However, when the
mortgagee's right to foreclosure is contested, the legal proceedings necessary
to resolve the issue can be time consuming. After the completion of judicial
foreclosure, the court would issue a judgment of foreclosure and would generally
appoint a referee or other court officer to conduct the sale of the property.
 
     Foreclosure of a deed of trust is generally accomplished by non-judicial
trustee's sale under a specific provision in the deed of trust which authorizes
the trustee to sell the property to a third party upon any default by the
trustor under the terms of the note or deed of trust. In some states, the
trustee must record a notice of default and send a copy to the borrower or any
person who has recorded a request for a copy of a notice of default and notice
of sale. In addition, the trustee must provide notice in some states to any
other individual having an interest in the real property, including any junior
lienholders. The Mortgagor, or any other person having a junior encumbrance on
the real estate, may, during a reinstatement period, cure the default by paying
the entire amount in arrears, plus the costs and expenses incurred in enforcing
the obligation. Generally, state law controls the amount of foreclosure expenses
and costs, including limiting attorneys' fees, which may be recovered by a
lender. If the deed of trust is not reinstated, a notice of sale must be posted
in a public place and, in most states, published for a specified 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 receiver or other designated officer or by the trustee is a public sale.
However, because of the difficulty a potential buyer at the sale would have in
determining the exact status of title and because the physical condition of the
property may have deteriorated during the foreclosure proceedings, it is
uncommon for a third party to purchase the property at a foreclosure sale.
Rather, it is common for the lender to purchase the property from the trustee or
referee for an amount equal to the principal amount of the mortgage or deed of
trust, accrued and unpaid interest and the expenses of foreclosure. Thereafter,
the lender will assume the burdens of ownership, including obtaining casualty
insurance and making such repairs at its own expense as are necessary to render
the property suitable for sale. The lender will commonly obtain the services of
a real estate broker and pay the broker's commission in connection with the sale
of the property. Depending upon market conditions, the ultimate proceeds of the
sale of the property may not equal the lender's investment in the property. Any
loss may be reduced by the receipt of mortgage insurance proceeds.
 
     Courts have usually imposed general equitable principles upon foreclosure
proceedings. These equitable principles are generally designed to relieve the
trustor 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 actions to determine the causes for the
Mortgagors' default and the likelihood that the Mortgagor 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 Mortgagors who are suffering from a
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 Mortgagor failing to adequately maintain the property or
the Mortgagor 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 trustors under deeds of trust 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 does not involve sufficient state action
to afford constitutional protections to the trustor.
 
     Shares of Cooperatives.  The cooperative shares owned by the
tenant-stockholder and pledged to the lender are, in almost all cases, subject
to restrictions on transfer as set forth in the cooperative's certificate of
incorporation and by-laws, as well as in the proprietary lease or occupancy
agreement, and may be cancelled by the cooperative for failure by the
tenant-stockholder to pay rent or other obligations or charges owed by such
tenant-stockholder, including mechanics' liens against the cooperative apartment
building incurred by such tenant-stockholder. The proprietary lease or occupancy
agreement generally permits the cooperative to terminate such lease or agreement
in the event an obligor fails to make payments or defaults in the
 
                                       43
<PAGE>   112
 
performance of covenants required thereunder. Typically, the lender and the
cooperative enter into a recognition agreement which establishes the rights and
obligations of both parties in the event of a default by the tenant-stockholder
on its obligations under the proprietary lease or occupancy agreement. A default
by the tenant-stockholder under the proprietary lease or occupancy agreement
will usually constitute a default under the security agreement between the
lender and the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the cooperative will recognize the
lender's lien against proceeds from a sale of the cooperative apartment,
subject, however, to the cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the cooperative loan and accrued and unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
cooperative loan, the lender must obtain the approval or consent of the
cooperative as required by the proprietary lease before transferring the
cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     Foreclosure on cooperative shares is accomplished by a sale in accordance
with the provisions of Article 9 of the Uniform Commercial Code (the "UCC") and
the security agreement relating to those shares. Article 9 of the UCC requires
that a sale be conducted in a "commercially reasonable" manner. Whether a
foreclosure sale has been conducted in a "commercially reasonable" manner will
depend on the facts in each case. In determining commercial reasonableness, a
court will look to the notice given the debtor and the method, manner, time,
place and terms of the foreclosure. Generally, a sale conducted according to the
usual practice of banks selling similar collateral will be considered reasonably
conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to the
reimbursement is subject to the right of the cooperative corporation to receive
sums due under the proprietary lease or occupancy agreement. If there are
proceeds remaining, the lender must account to the tenant-stockholder for the
surplus. Conversely, if a portion of the indebtedness remains unpaid, the
tenant-stockholder is generally responsible for the deficiency. See
"Anti-Deficiency Legislation and Other Limitations on Sellers" below.
 
     Leasehold Risks.  Mortgage Loans may be secured by a mortgage on a ground
lease. Leasehold mortgages are subject to certain risks not associated with
mortgage loans secured by the fee estate of the mortgagor. The most significant
of these risks is that the ground lease creating the leasehold estate could
terminate, leaving the leasehold mortgagee without its security. The ground
lease may terminate, if among other reasons, the ground lessee breaches or
defaults in its obligations under the ground lease or there is a bankruptcy of
the ground lessee or the ground lessor. This risk may be minimized if the ground
lease contains certain provisions protective of the mortgagee, but the ground
leases that secure Mortgage Loans may not contain some of these protective
provisions, and mortgages may not contain the other protection discussed in the
next paragraph. Protective ground lease provisions include the right of the
leasehold mortgagee to receive notices from the ground lessor of any defaults by
the mortgagor; the right to cure such defaults, with adequate cure periods; if a
default is not susceptible of cure by the leasehold mortgagee, the right to
acquire the leasehold estate through foreclosure or otherwise; the ability of
the ground lease to be assigned to and by the leasehold mortgagee or purchaser
at a foreclosure sale and for the concomitant release of the ground lessee's
liabilities thereunder; and the right of the leasehold mortgagee to enter into a
new ground lease with the ground lessor on the same terms and conditions as the
old ground lease in the event of a termination thereof.
 
     In addition to the foregoing protections, a leasehold mortgagee may require
that the ground lease or leasehold mortgage prohibit the ground lessee from
treating the ground lease as terminated in the event of the ground lessor's
bankruptcy and rejection of the ground lease by the trustee for the
debtor-ground lessor. As
 
                                       44
<PAGE>   113
 
further protection, a leasehold mortgage may provide for the assignment of the
debtor-ground lessee's right to reject a lease pursuant to Section 365 of the
Bankruptcy Reform Act of 1978, as amended (11 U.S.C.) (the "Bankruptcy Code"),
although the enforceability of such clause has not been established. Without the
protections described in the foregoing paragraph, a leasehold mortgagee may lose
the collateral securing its leasehold mortgage. In addition, terms and
conditions of a leasehold mortgage are subject to the terms and conditions of
the ground lease. Although certain rights given to a ground lessee can be
limited by the terms of a leasehold mortgage, the rights of a ground lessee or a
leasehold mortgagee with respect to, among other things, insurance, casualty and
condemnation will be governed by the provisions of the ground lease.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of
the mortgage, the Mortgagor and foreclosed junior lienors are given a statutory
period in which to redeem the property from the foreclosure sale. The right of
redemption should be distinguished from the equity of redemption, which is a
nonstatutory right that must be exercised prior to the foreclosure sale. In some
states, redemption may occur only upon payment of the entire principal balance
of the loan, accrued interest and expenses of foreclosure. In other states,
redemption may be authorized if the former Mortgagor pays only a portion of the
sums due. The effect of a statutory right of redemption is to diminish the
ability of the lender to sell the foreclosed property. The right of redemption
would defeat the title of any purchaser from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON SELLERS
 
     Certain states have imposed statutory prohibitions which restrict or
eliminate the remedies of a beneficiary under a deed of trust or a mortgagee
under a mortgage. In some states, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the Mortgagor following
foreclosure or sale under a deed of trust. A deficiency judgment would be a
personal judgment against the former Mortgagor equal in most cases to the
difference between the net amount realized upon the public sale of the real
property and the amount due to the lender. Other statutes may 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 Mortgagor. Finally, other statutory
provisions may limit any deficiency judgment against the former Mortgagor
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 to prevent a beneficiary or a mortgagee from obtaining a large
deficiency judgment against the former Mortgagor as a result of low or no bids
at the judicial sale.
 
     In addition to anti-deficiency and related legislation, numerous other
statutory provisions, including the federal bankruptcy laws and state laws
affording relief to debtors, may interfere with or affect the ability of the
secured mortgage lender to realize upon its security. The Internal Revenue Code
of 1986, as amended, provides priority to certain tax liens over the lien of the
mortgage. Numerous federal and some state consumer protection laws impose
substantive requirements upon mortgage lenders in connection with the
origination and the servicing of mortgage loans. These laws include the federal
Truth-in-Lending Act, Real Estate Settlement Procedures Act, Equal Credit
Opportunity Act, Fair Credit Billing Act, Fair Credit Reporting Act and related
statutes. These federal laws impose specific statutory liabilities upon lenders
who originate mortgage loans and who fail to comply with the provisions of the
law. In some cases, this liability may affect assignees of the mortgage loans.
 
DUE-ON-SALE CLAUSES
 
     Unless otherwise provided in the related Supplement, each conventional
Mortgage Loan will contain a due-on-sale clause which will generally provide
that if the mortgagor or obligor sells, transfers or conveys the Mortgaged
Property, the loan may be accelerated by the mortgagee. In recent years, court
decisions and legislative actions have placed substantial restriction on the
right of lenders to enforce such clauses in many states. For instance, the
California Supreme Court in August 1978 held that due-on-sale clauses were
 
                                       45
<PAGE>   114
 
generally unenforceable. However, the Garn-St Germain Depository Institutions
Act of 1982 (the "Garn-St Germain Act"), subject to certain exceptions, preempts
state constitutional, statutory and case law prohibiting the enforcement of
due-on-sale clauses. As to loans secured by an owner-occupied residence, the
Garn-St Germain Act sets forth nine specific instances in which a mortgagee
covered by the Garn-St Germain Act may not exercise its rights under a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have occurred. The inability to enforce a due-on-sale clause may result in
transfer of the related Mortgaged Property to an uncreditworthy person, which
could increase the likelihood of default or may result in a mortgage bearing an
interest rate below the current market rate being assumed by a new home buyer,
which may affect the average life of the Mortgage Loans and the number of
Mortgage Loans which may extend to maturity.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V"), provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The Office of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized to
issue rules and regulations and to publish interpretations governing
implementation of Title V. The statute authorized the states to reimpose
interest rate limits by adopting, before April 1, 1983, a law or constitutional
provision which expressly rejects an application of the federal law. In
addition, even where Title V is not so rejected, any state is authorized by the
law to adopt a provision limiting discount points or other charges on mortgage
loans covered by Title V. Certain states have taken action to reimpose interest
rate limits and/or to limit discount points or other charges.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT
 
     Generally, under the terms of the Soldiers' and Sailors' Civil Relief Act
of 1940, as amended (the "Relief Act"), a borrower who enters military service
after the origination of such borrower's Mortgage Loan (including a borrower who
is a member of the National Guard or is in reserve status at the time of the
origination of the Mortgage Loan and is later called to active duty) may not be
charged interest above an annual rate of 6% during the period of such borrower's
active duty status, unless a court orders otherwise upon application of the
lender. It is possible that such interest rate limitation could have an effect,
for an indeterminate period of time, on the ability of the Servicer to collect
full amounts of interest on certain of the Mortgage Loans. In addition, the
Relief Act imposes limitations which would impair the ability of the Servicer to
foreclose on an affected Mortgage Loan during the borrower's period of active
duty status. Thus, in the event that such a Mortgage Loan goes into default
there may be delays and losses occasioned by the inability to realize upon the
mortgaged property in a timely fashion. As used herein, a "Relief Act Mortgage
Loan" refers to any Mortgage Loan as to which the Relief Act has limited the
amount of interest the related Mortgagor is required to pay each month.
 
ENVIRONMENTAL LEGISLATION
 
     Certain states impose a statutory lien for associated costs on property
that is the subject of a cleanup action by the state on account of hazardous
wastes or hazardous substances released or disposed of on the property. Such a
lien will generally have priority over all subsequent liens on the property and,
in certain of these states, will have priority over prior recorded liens
including the lien of a mortgage. In addition, under federal environmental
legislation and possibly under state law in a number of states, a secured party
which takes a deed in lieu of foreclosure or acquires a mortgaged property at a
foreclosure sale or otherwise is deemed an "owner" or "operator" of the property
may be liable for the costs of cleaning up a contaminated site. Although such
costs could be substantial, it is unclear whether they would be imposed on a
secured lender.

<PAGE>   115
 
                              ERISA CONSIDERATIONS
 
     ERISA and Section 4975 of the Code impose certain requirements on those
employee benefit plans and arrangements to which either ERISA or the Code
applies (each a "Plan") and on those persons who are fiduciaries with respect to
such Plans. In accordance with ERISA's general fiduciary standards, before
investing in a Certificate a Plan fiduciary should determine whether such an
investment is permitted under the governing Plan instruments and is appropriate
for the Plan in view of its overall investment policy and the composition and
diversification of its portfolio. Other provisions of ERISA and the Code
prohibit certain transactions involving the assets of a Plan and persons who
have certain specified relationships to the Plan (i.e., "parties in interest"
within the meaning of ERISA or "disqualified persons" within the meaning of the
Code). Thus, a Plan fiduciary considering an investment in Certificates should
also consider whether such an investment might constitute or give rise to a
prohibited transaction under ERISA or the Code.
 
PLAN ASSETS REGULATIONS
 
     If an investing Plan's assets were deemed to include an undivided ownership
interest in the assets included in a Pool, a Plan's investment in the
Certificates might be deemed to constitute a delegation under ERISA of the duty
to manage Plan assets by the fiduciaries deciding to invest in the Certificates,
and certain transactions involved in the operation of the Pool might be deemed
to constitute prohibited transactions under ERISA and the Code. ERISA and the
Code do not define "plan assets". The U.S. Department of Labor has published
regulations (the "Labor Regulations") concerning whether or not a Plan's assets
would be deemed to include an interest in the underlying assets of an entity for
purposes of the reporting, disclosure and fiduciary responsibility provisions of
ERISA, if the Plan acquires an "equity interest" in such entity (such as by
acquiring Certificates). The Labor Regulations state that the underlying assets
of an entity will not be considered "plan assets" if, immediately after the most
recent acquisition of any equity interest in the entity, whether from the issuer
or an underwriter, less than twenty-five percent (25%) of the value of each
class of equity interest is held by "benefit plan investors", individual
retirement accounts, and other employee benefit plans not subject to ERISA (for
example, governmental plans). The Sponsor cannot predict whether under the Labor
Regulations the assets of a Plan investing in Certificates will be deemed to
include an interest in the assets of the Pool.
 
     The Labor Regulations provide that where a Plan acquires a "guaranteed
governmental mortgage pool certificate", the Plan's assets include such
certificate but do not solely by reason of the Plan's holdings of such
certificate include any of the mortgages underlying such certificate. The Labor
Regulations include in the definition of a "guaranteed governmental mortgage
pool certificate" the types of FHLMC Certificates, GNMA Certificates and FNMA
Certificates which may be included in a Pool underlying a Series of
Certificates. Accordingly, even if such Mortgage Certificates included in a Pool
were deemed to be assets of Plan investors, the mortgages underlying such
Mortgage Certificates would not be treated as assets of such Plans. Private
Certificates are not "guaranteed governmental mortgage pool certificates".
Potential Plan investors should consult the ERISA discussion in the related
Supplement before purchasing any such Certificates.
 
UNDERWRITER'S EXEMPTIONS
 
     The U.S. Department of Labor has granted to certain underwriters individual
administrative exemptions (the "Underwriter's Exemptions") from certain of the
prohibited transaction rules of ERISA and the related excise tax provisions of
Section 4975 of the Code with respect to the initial purchase, the holding and
the subsequent resale by Plans of certificates in pass-through trusts that
consist of certain receivables, loans and other obligations that meet the
conditions and requirements of the Underwriter's Exemptions.
 
                                       47
<PAGE>   116
 
     While each Underwriter's Exemption is an individual exemption separately
granted to a specific underwriter, the terms and conditions which generally
apply to the Underwriter's Exemptions are substantially identical, and include
the following:
 
          (1) the acquisition of the certificates by a Plan is on terms
     (including the price for the certificates) that are at least as favorable
     to the Plan as they would be in an arm's-length transaction with an
     unrelated party;
 
          (2) the rights and interest evidenced by the certificates acquired by
     the Plan are not subordinated to the rights and interests evidenced by
     other certificates of the trust fund;
 
          (3) the certificates required by the Plan have received a rating at
     the time of such acquisition that is one of the three highest generic
     rating categories from Standard & Poor's Ratings Group, a division of The
     McGraw-Hill Companies ("S&P"), Moody's Investors Service, Inc. ("Moody's"),
     Duff & Phelps Credit Rating Co. ("D&P") or Fitch Investors Service, L.P.
     ("Fitch");
 
          (4) the trustee must not be an affiliate of any other member of the
     Restricted Group;
 
          (5) the sum of all payments made to and retained by the underwriters
     in connection with the distribution of the certificates represents not more
     than reasonable compensation for underwriting the certificates; the sum of
     all payments made to and retained by the seller pursuant to the assignment
     of the loans to the trust fund represents not more than the fair market
     value of such loans; the sum of all payments made to and retained by the
     servicer and any other servicer represents not more than reasonable
     compensation for such person's services under the agreement pursuant to
     which the loans are pooled and reimbursements of such person's reasonable
     expenses in connection therewith; and
 
          (6) the Plan investing in the certificates is an "accredited investor"
     as defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange
     Commission under the Securities Act.
 
     The trust fund must also meet the following requirements:
 
          (i) the corpus of the trust fund must consist solely of assets of the
     type that have been included in other investment pools;
 
          (ii) certificates in such other investment pools must have been rated
     in one of the three highest rating categories of S&P, Moody's, Fitch or D&P
     for at least one year prior to the Plan's acquisition of certificates; and
 
          (iii) certificates evidencing interests in such other investment pools
     must have been purchased by investors other than Plans for at least one
     year prior to any Plan's acquisition of certificates.
 
     Moreover, the Underwriter's Exemptions generally provide relief from
certain self-dealing/conflict of interest prohibited transactions that may occur
when the Plan fiduciary causes a Plan to acquire certificates in a trust as to
which the fiduciary (or its affiliate) is an obligor on the receivables held in
the trust provided that, among other requirements: (i) in the case of an
acquisition in connection with the initial issuance of certificates, at least
fifty percent (50%) of each class of certificates in which Plans have invested
is acquired by persons independent of the Restricted Group, (ii) such fiduciary
(or its affiliate) is an obligor with respect to five percent (5%) or less of
the fair market value of the obligations contained in the trust; (iii) the
Plan's investment in certificates of any class does not exceed twenty-five
percent (25%) of all of the certificates of that class outstanding at the time
of the acquisition; and (iv) immediately after the acquisition, no more than
twenty-five percent (25%) of the assets of the Plan with respect to which such
person is a fiduciary is invested in certificates representing an interest in
one or more trusts containing assets sold or serviced by the same entity. The
Underwriter's Exemptions do not apply to Plans sponsored by the Seller, the
related underwriter, the Trustee, the Servicer, any insurer with respect to the
Mortgage Loans, any obligor with respect to Mortgage Loans included in the Trust
Fund constituting more than five percent (5%) of the aggregate unamortized
principal balance of the assets in the Trust Fund, or any affiliate of such
parties.
 
     The Supplement for each Series of Certificates will indicate the classes of
Certificates, if any, offered thereby as to which it is expected than an
Underwriter's Exemption will apply.

OTHER EXEMPTIONS
 
     In addition to making its own determination as to the availability of the
exemptive relief provided in the Underwriter's Exemptions, the Plan fiduciary
should consider the possible availability of any other prohibited transaction
exemptions, in particular, Prohibited Transaction Class Exemption 83-1 for
Certain Transactions Involving Mortgage Pool Investment Trusts ("PTE 83-1"). PTE
83-1 permits certain transactions involving the creation, maintenance and
termination of certain residential mortgage pools and the acquisition and
holding of certain residential mortgage pool pass-through certificates by Plans,
whether or not the Plan's assets would be deemed to include an ownership
interest in the mortgages in the mortgage pool, and whether or not such
transactions would otherwise be prohibited under ERISA. The Sponsor believes
that the "general conditions" set forth in Section II of PTE 83-1, which are
required for its applicability, would be met with respect to most classes of
Certificates evidencing ownership interest in a Pool consisting solely of
Mortgage Loans secured by first or second mortgages or deeds of trust on
single-family residential property. PTE 83-1 would not apply to Certificates
which are part of a class that is subordinate to one or more other classes of
the same Series of Certificates. It is not clear whether PTE 83-1 applies to
Residual Certificates, Certificates which do not pass through both principal and
interest, to any Certificates evidencing ownership interests in a Pool
containing Mortgage Certificates, or to any Certificates evidencing ownership
interests in the reinvestment income of funds on deposit in the related
Certificate Account or in Mortgage Loans secured by shares in a cooperative
corporation. Before purchasing any Certificates, a Plan fiduciary should consult
with its counsel and determine whether PTE 83-1 applies, including whether the
appropriate "specific conditions" set forth in Section I of PTE 83-1, in
addition to the "general conditions" set forth in Section II, would be met, or
whether any other ERISA prohibited transaction exemption is applicable.
Furthermore, a Plan fiduciary should consult the ERISA discussion in the related
Supplement relating to a Series of Certificates before purchasing Certificates.
 
     The Sponsor, or certain affiliates of the Sponsor, might be considered or
might become "parties in interest" (as defined under ERISA) or "disqualified
persons" (as defined under the Code) with respect to a Plan. If so, the
acquisition or holding of Certificates by or on behalf of such Plan could be
considered to give rise to a "prohibited transaction" within the meaning of
ERISA and the Code unless PTE 83-1, the Underwriter's Exemptions, or some other
exemption as available. Special caution ought to be exercised before a Plan
purchases a Certificate in such circumstances.
 
     Employee benefit plans which are governmental plans (as defined in Section
3(32) of ERISA), and certain church plans (as defined in Section 3(33) of
ERISA), are not subject to the ERISA fiduciary requirements. However, the
purchase of a Residual Certificate by some of such plans, or by most varieties
of ERISA Plans, may give rise to "unrelated business taxable income" as
described in Sections 511-515 and 860E of the Code. Prior to the purchase of
Residual Certificates, a prospective purchaser may be required to provide an
affidavit to the Trustee and the Sponsor that it is not a "disqualified
organization", which term as defined herein includes certain tax-exempt entities
not subject to Section 511 of the Code, including certain governmental plans. In
addition, prior to the transfer of a Residual Certificate, the Trustee or the
Sponsor may require an opinion of counsel to the effect that such transfer will
not result in a violation of the prohibited transactions provisions of ERISA and
the Code and will not subject the Trustee, the Sponsor or the Servicer to
additional obligations.
 
     Due to the complexity of these rules and the penalties imposed upon persons
involved in prohibited transactions, it is particularly important that potential
Plan investors consult with their counsel regarding the consequences under ERISA
and the Code of their acquisition and ownership of Certificates.
 
                         LEGAL INVESTMENT CONSIDERATION
 
     Institutions whose investment activities are subject to legal investment
laws and regulations or to review by certain regulatory authorities may be
subject to restrictions on investment in certain types of Certificates. Any
financial institution that is subject to the jurisdiction of the Comptroller of
the Currency, the Board of Governors of the Federal Reserve System, the Federal
Deposit Insurance Corporation, the Office of Thrift Supervision, the National
Credit Union Administration or other federal or state agencies with similar
 
                                       49
<PAGE>   118
 
authority should review any applicable rules, guidelines and regulations prior
to purchasing any Certificates. Financial institutions should review and
consider the applicability of the Federal Financial Institutions Examination
Council Supervisory Policy Statement on Securities Activities (to the extent
adopted by their respective federal regulators), which, among other things, set
forth guidelines for investing in certain types of mortgage related securities,
including securities such as the Certificates. In addition, financial
institutions should consult their regulators concerning the risk-based capital
treatment of any Certificates. Investors should consult their own legal advisors
in determining whether and to what extent Certificates constitute legal
investments or are subject to restrictions on investment.
 
                                 LEGAL MATTERS
 
     The validity of the Certificates, including certain federal income tax
consequences with respect thereto, will be passed upon for the Sponsor by Brown
& Wood, One World Trade Center, New York, New York 10048.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following summary of the anticipated material federal income tax
consequences of the purchase, ownership and disposition of Certificates is based
on the advice of Brown & Wood, counsel to the Sponsor. This summary is based on
laws, regulations, including the REMIC regulations promulgated by the Treasury
Department on December 23, 1992, and generally effective for REMICs with
start-up dates on or after November 12, 1991 (the "REMIC Regulations"), rulings
and decisions now in effect or (with respect to regulations) proposed, all of
which are subject to change either prospectively or retroactively. This summary
does not address the federal income tax consequences of an investment in
Certificates applicable to all categories of investors, some of which (for
example, banks and insurance companies) may be subject to special rules.
Prospective investors should consult their tax advisors regarding the federal,
state, local and any other tax consequences to them of the purchase, ownership
and disposition of Certificates.
 
GENERAL
 
     The federal income tax consequences to Certificateholders will vary
depending on whether an election is made to treat the Pool relating to a
particular Series of Certificates as a real estate mortgage investment conduit
("REMIC") under the Internal Revenue Code of 1986, as amended (the "Code"). The
Supplement for each Series of Certificates will specify whether a REMIC election
will be made.
 
NON-REMIC CERTIFICATES
 
     If a REMIC election is not made, Brown & Wood will deliver its opinion that
the Pool will be classified as a grantor trust under subpart E, Part I of
subchapter J of the Code. In this case, owners of Certificates will be treated
for federal income tax purposes as owners of a portion of the Pool's assets as
described below.
 
SINGLE CLASS OF SENIOR CERTIFICATES
 
     Characterization.  The Pool may be created with one class of Senior
Certificates and one class of Subordinate Certificates. In this case, each
Senior Certificateholder will be treated as the owner of a pro rata undivided
interest in the interest and principal portions of the Pool represented by that
Senior Certificate and will be considered the equitable owner of a pro rata
undivided interest in each of the Mortgage Loans in the Pool. Any amounts
received by a Senior Certificateholder in lieu of amounts due with respect to
any Mortgage Loan because of a default or delinquency in payment will be treated
for federal income tax purposes as having the same character as the payments
they replace.
 
     Each holder of a Senior Certificate will be required to report on its
federal income tax return its pro rata share of the entire income from the
Mortgage Loans in the Pool represented by that Senior Certificate, including
interest, original issue discount, if any, prepayment fees, assumption fees, any
gain recognized upon an assumption and late payment charges received by the
Servicer in accordance with such Senior Certificate-
 
                                       50
<PAGE>   119
 
holder's method of accounting. Under Code Sections 162 or 212 each Senior
Certificateholder will be entitled to deduct its pro rata share of servicing
fees, prepayment fees, assumption fees, any loss recognized upon an assumption
and late payment charges retained by the Servicer, provided that such amounts
are reasonable compensation for services rendered to the Pool. Senior
Certificateholders that are individuals, estates or trusts will be entitled to
deduct their share of expenses only to the extent such expenses plus all other
Code Section 212 expenses exceed two percent of its adjusted gross income. A
Senior Certificateholder using the cash method of accounting must take into
account its pro rata share of income and deductions as and when collected by or
paid to the Servicer. A Senior Certificateholder using an accrual method of
accounting must take into account its pro rata share of income and deductions as
they become due or are paid to the Servicer, whichever is earlier. If the
Servicing Fees paid to the Servicer were deemed to exceed reasonable servicing
compensation, the amount of such excess could be considered as a retained
ownership interest by the Servicer (or any person to whom the Servicer assigned
for value all or a portion of the Servicing Fees) in a portion of the interest
payments on the Mortgage Loans. The Mortgage Loans may then be subject to the
"coupon stripping" rules of the Code discussed below.
 
     Unless otherwise specified in the related Supplement, as to each series of
Certificates Brown & Wood will have advised the Sponsor that:
 
          (i) a Senior Certificate owned by a "domestic building and loan
     association" within the meaning of Code Section 7701(a)(19) representing
     principal and interest payments on Mortgage Loans will be considered to
     represent "loans . . . secured by an interest in real property which
     is . . . residential property" within the meaning of Code Section
     7701(a)(19)(C)(v); provided that the real property securing the Mortgage
     Loans represented by that Senior Certificate is of a type described in such
     Code section;
 
        (ii) a Senior Certificate owned by a financial institution described in
     Code Section 593(a) representing principal and interest payments on
     Mortgage Loans will be considered to represent "qualifying real property
     loans" within the meaning of Code Section 593(d) and the Treasury
     regulations under Code Section 593; provided that the real property
     securing the Mortgage Loans represented by that Senior Certificate is of a
     Type described in such Code section;
 
          (iii) a Senior Certificate owned by a real estate investment trust
     representing an interest in Mortgage Loans will be considered to represent
     "real estate assets" within the meaning of Code Section 856(c)(5)(A), and
     interest income on the Mortgage Loans will be considered "interest on
     obligations secured by mortgages on real property" within the meaning of
     Code Section 856(c)(3)(B); provided that the real property securing the
     Mortgage Loans represented by that Senior Certificate is of a type
     described in such Code section; and
 
          (iv) a Senior Certificate owned by a REMIC will be an
     "obligation . . . which is principally secured, directly or indirectly, by
     an interest in real property" within the meaning of Code Section
     860G(a)(3).
 
     The assets constituting certain Pools may include Buydown Mortgage Loans.
The characterization of any investment in Buydown Mortgage Loans will depend
upon the precise terms of the related Buydown Agreement, but to the extent that
such Buydown Mortgage Loans are secured in part by a bank account or other
personal property, they may not be treated in their entirety as assets described
in the foregoing sections of the Code. There are no directly applicable
precedents with respect to the federal income tax treatment or the
characterization of investments in Buydown Mortgage Loans. Accordingly, holders
of Senior Certificates should consult their own tax advisors with respect to
characterization of investments in Senior Certificates representing an interest
in a Pool that includes Buydown Mortgage Loans.
 
     Premium.  The price paid for a Senior Certificate by a holder will be
allocated to such holder's undivided interest in each Mortgage Loan based on
each Mortgage Loan's relative fair market value, so that such holder's undivided
interest in each Mortgage Loan will have its own tax basis. A Senior
Certificateholder that acquires an interest in Mortgage Loans at a premium may
elect to amortize such premium under a constant interest method, provided that
such Mortgage Loan was originated after September 27, 1985. Premium allocable to
a Mortgage Loan originated on or before September 27, 1985 should be allocated
among the principal payments on the Mortgage Loan and allowed as an ordinary
deduction as principal
 
                                       51
<PAGE>   120
 
payments are made. Amortizable bond premium will be treated as an offset to
interest income on such Senior Certificate. The basis for such Senior
Certificate will be reduced to the extent that amortizable premium is applied to
offset interest payments.
 
     It is not clear whether a reasonable prepayment assumption should be used
in computing amortization of premium allowable under Code Section 171.
 
     If a premium is not subject to amortization using a reasonable prepayment
assumption, the holder of a Senior Certificate acquired at a premium should
recognize a loss, if a Mortgage Loan prepays in full, equal to the difference
between the portion of the prepaid principal amount of the Mortgage Loan that is
allocable to the Certificate and the portion of the adjusted basis of the
Certificate that is allocable to the Mortgage Loan. If a reasonable prepayment
assumption is used to amortize such premium, it appears that such a loss would
be available, if at all, only if prepayments have occurred at a rate faster than
the reasonable assumed prepayment rate. It is not clear whether any other
adjustments would be required to reflect differences between an assumed
prepayment rate and the actual rate of prepayments.
 
     Original Issue Discount.  The Internal Revenue Service (the "IRS") has
stated in published rulings that, in circumstances similar to those described
herein, the special rules of the Code relating to "original issue discount"
(currently Code Sections 1271 through 1273 and 1275) will be applicable to a
Senior Certificateholder's interest in those Mortgage Loans meeting the
conditions necessary for these sections to apply. Rules regarding periodic
inclusion of original issue discount income are applicable to mortgages of
corporations originated after May 27, 1969, mortgages of noncorporate mortgagors
(other than individuals) originated after July 1, 1982, and mortgages of
individuals originated after March 2, 1984. Such original issue discount could
arise by the financing of points or other charges by the originator of the
mortgages in an amount greater than a statutory de minimis exception to the
extent that the points are not currently deductible under applicable Code
provisions or are not for services provided by the lender. Additionally, under
regulations issued on January 27, 1994 with respect to original issue discount
(the "OID Regulations"), original issue discount may be created when the rate
produced (on the issue date) by the index formula on an adjustable rate mortgage
("ARM") is greater than the initial interest rate payable on the ARM. Original
issue discount generally must be reported as ordinary gross income as it accrues
under a constant interest method. See "Accrual of Original Issue Discount" under
"Multiple Classes of Senior Certificates" below.
 
     Market Discount.  A Senior Certificateholder that acquires an undivided
interest in Mortgage Loans may be subject to the market discount rules of Code
Sections 1276 through 1278 to the extent an undivided interest in a Mortgage
Loan is considered to have been purchased at a "market discount". (Generally,
market discount is the excess of the portion of the principal amount of such
Mortgage Loan allocable to such holder's undivided interest over such holder's
tax basis in such interest). Market discount with respect to a Senior
Certificate will be considered to be zero if the amount allocable to the Senior
Certificate is less than 0.25% of the Senior Certificate's stated redemption
price at maturity multiplied by the weighted average maturity remaining after
the date of purchase. Treasury regulations implementing the market discount
rules have not yet been issued; therefore, investors should consult their own
tax advisors regarding the application of these rules and the advisability of
making any of the elections allowed under Code Sections 1276 through 1278.
 
     The Code provides that any principal payment (whether a scheduled payment
or a prepayment) or any gain on disposition of a market discount bond acquired
by the taxpayer after October 22, 1986 shall be treated as ordinary income to
the extent that it does not exceed the accrued market discount at the time of
such payment. The amount of accrued market discount for purposes of determining
the tax treatment of subsequent principal payments or dispositions of the market
discount bond is to be reduced by the amount so treated as ordinary income.
 
     The Code also grants the Treasury Department authority to issue regulations
providing for the computation of accrued market discount on debt instruments,
the principal of which is payable in more than one installment. While the
Treasury Department has not yet issued regulations, rules described in the
relevant legislative history will control. Under those rules, the holder of a
market discount bond may elect to accrue market discount either on the basis of
a constant interest rate or according to one of the following methods. If a
Senior Certificate is issued with original issue discount, the amount of market
discount that accrues during
 
                                       52
<PAGE>   121
 
any accrual period would be equal to the product of (i) the total remaining
market discount, multiplied by (ii) a fraction, the numerator of which is the
original issue discount accruing during the period and the denominator of which
is the total remaining original issue discount at the beginning of the accrual
period. For Senior Certificates issued without original issue discount, the
amount of market discount that accrues during a period is equal to the product
of (i) the total remaining market discount, multiplied by (ii) a fraction, the
numerator of which is the amount of stated interest paid during the accrual
period and the denominator of which is the total amount of stated interest
remaining to be paid at the beginning of the accrual period. For purposes of
calculating market discount under any of the above methods in the case of
instruments (such as the Senior Certificates) which provide for payments which
may be accelerated by reason of prepayments of other obligations securing such
instruments, the same prepayment assumption applicable to calculating the
accrual of original issue discount will apply. Because the regulations described
above have not been issued, it is impossible to predict what effect those
regulations might have on the tax treatment of a Senior Certificate purchased at
a discount or premium in the secondary market.
 
     A holder who acquired a Senior Certificate at a market discount also may be
required to defer, until the maturity date of such Senior Certificate or its
earlier disposition in a taxable transaction, the deduction of a portion of the
amount of interest that the holder paid or accrued during the taxable year on
indebtedness incurred or maintained to purchase or carry the Senior Certificate
in excess of the aggregate amount of interest (including original issue
discount) includible in such holder's gross income for the taxable year with
respect to such Senior Certificate. The amount of such net interest expense
deferred in a taxable year may not exceed the amount of market discount accrued
on the Senior Certificate for the days during the taxable year on which the
holder held the Senior Certificate and, in general, would be deductible when
such market discount is includible in income. The amount of any remaining
deferred deduction is to be taken into account in the taxable year in which the
Senior Certificate matures or is disposed of in a taxable transaction. In the
case of a disposition in which gain or loss is not recognized in whole or in
part, any remaining deferred deduction will be allowed to the extent of gain
recognized on the disposition. This deferral rule does not apply, if the Senior
Certificateholder elects to include such market discount in income currently as
it accrues on all market discount obligations acquired by such Senior
Certificateholder in that taxable year or thereafter.
 
MULTIPLE CLASSES OF SENIOR CERTIFICATES
 
     Stripped Bonds and Stripped Coupons.  Pursuant to Code Section 1286, 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 on such obligation results in the creation of "stripped
bonds" with respect to principal payments and "stripped coupons" with respect to
interest payments. For purposes of Code Sections 1271 through 1288, Code Section
1286 treats a stripped bond or a stripped coupon as an obligation issued on the
date that such stripped interest is purchased. If a Pool is created with two
classes of Senior Certificates, one class of Senior Certificates will represent
the right to principal and interest, or principal only, on all or a portion of
the Loans (the "Stripped Bond Certificates"), while the second class of Senior
Certificates will represent the right to some or all of the interest on such
portion (the "Stripped Coupon Certificates").
 
     Although not entirely clear, based on recent IRS guidance, a Stripped Bond
Certificate generally should be treated as a single debt instrument issued on
the day it is purchased for purposes of calculating any original issue discount.
Generally, if the discount on a Stripped Bond Certificate is larger than a de
minimis amount (as calculated for purposes of the original issue discount rules)
a purchaser of such a certificate will be required to accrue the discount under
the original issue discount rules of the Code. See "Non-REMIC
Certificates -- Single Class of Senior Certificates -- Original Issue Discount"
herein. However, a purchaser of a Stripped Bond Certificate will be required to
account for any discount on the certificate as market discount rather than
original issue discount if either (i) the amount of original issue discount with
respect to the certificate was treated as zero under the original issue discount
de minimis rule when the certificate was stripped or (ii) no more than 100 basis
points (including any amount of servicing in excess of reasonable servicing) is
stripped off of the Pool's Loans. See "Certain Federal Income Tax
Consequences -- Non-REMIC Certificates -- Single Class of Senior
Certificates -- Market Discount" herein. Pursuant to Revenue
 
                                       53
<PAGE>   122
 
Procedure 91-49, issued on August 8, 1991, purchasers of Stripped Bond
Certificates using an inconsistent method of accounting must change their method
of accounting and request the consent of the IRS to the change in their
accounting method on a statement attached to their first timely tax return filed
after August 8, 1991.
 
     The precise tax treatment of Stripped Coupon Certificates is substantially
uncertain. The Code could be read literally to require that original issue
discount computations be made on a Loan by Loan basis. However, based on the
recent IRS guidance, it appears that a Stripped Coupon Certificate should be
treated as a single installment obligation subject to the original issue
discount rules of the Code. As a result, all payments on a Stripped Coupon
Certificate would be included in the certificate's stated redemption price at
maturity for purposes of calculating income on such certificate under the
original issue discount rules of the Code.
 
     It is unclear under what circumstances, if any, the prepayment of Mortgage
Loans will give rise to a loss to the holder of a Stripped Bond Certificate
purchased at a premium or a Stripped Coupon Certificate. If such Certificate is
treated as a single instrument (rather than an interest in discrete mortgage
loans) and the effect of prepayments is taken into account in computing yield
with respect to such Senior Certificate, it appears that no loss may be
available as a result of any particular prepayment unless prepayments occur at a
rate faster than the assumed prepayment rate. However, if such Certificate is
treated as an interest in discrete Mortgage Loans, or if no prepayment
assumption is used, then when a Mortgage Loan is prepaid, the holder of such
Certificate should be able to recognize a loss equal to the portion of the
adjusted issue price of such Certificate that is allocable to such Mortgage
Loan.
 
     Holders of Stripped Bond Certificates and Stripped Coupon Certificates are
urged to consult with their own tax advisors regarding the proper treatment of
these Certificates for federal income tax purposes.
 
     Treatment of Certain Owners.  Several Code sections provide beneficial
treatment to certain taxpayers that invest in mortgage loans of the type that
make up the Pool. With respect to these Code sections, no specific legal
authority exists regarding whether the character of the Senior Certificates for
federal income tax purposes, will be the same as that of the underlying Mortgage
Loans. While Code Section 1286 treats a stripped obligation as a separate
obligation for purposes of the Code provisions addressing original issue
discount, it is not clear whether such characterization would apply with regard
to these other Code sections. Although the issue is not free from doubt, based
on policy considerations, each class of Senior Certificates should be considered
to represent "qualifying real property loans" within the meaning of Code Section
593(d), "real estate assets" within the meaning of Code Section 856(c)(5)(A) and
"loans . . . secured by, an interest in real property which is . . . residential
real property" within the meaning of Code Section 7701(a)(19)(C)(v), and
interest income attributable to Senior Certificates should be considered to
represent "interest on obligations secured by mortgages on real property".
Within the meaning of Code Section 856(c)(3)(B), provided that in each case the
underlying Mortgage Loans and interest on such Mortgage Loans qualify, for such
treatment. Prospective purchasers to which such characterization of an
investment in Senior Certificates is material should consult their own tax
advisors regarding the characterization of the Senior Certificates and the
income therefrom. Senior Certificates will be "obligation[s] (including any
participation or certificate of beneficial ownership therein) which [are]
principally secured, directly or indirectly, by an interest in real property"
within the meaning of Code Section 860G(a)(3).
 
     Senior Certificates Representing Interests in Loans Other Than
ARMs.  Original issue discount on each Senior Certificate must be included in
the owner's ordinary income for federal income tax purposes as it accrues, in
accordance with a constant interest method that takes into account the
compounding of interest, in advance of receipt of the cash attributable to such
income. Based in part on the OID Regulations, the amount of original issue
discount required to be included in an owner's income in any taxable year with
respect to a Senior Certificate representing an interest in Mortgage Loans other
than ARMs likely will be computed as described below under "-- Accrual of
Original Issue Discount." Owners should be aware, however, that the OID
Regulations either do not address, or are subject to varying interpretations
with regard to, several issues relevant to obligations, such as the Mortgage
Loans, which are subject to prepayment.
 
     Under the Code, the Mortgage Loans underlying the Senior Certificates will
be treated as having been issued on the date they were originated with an amount
of OID equal to the excess of such Mortgage Loan's
 
                                       54

stated redemption price at maturity over its issue price. The issue price of a
Mortgage Loan is generally the amount lent to the mortgagee, which may be
adjusted to take into account certain loans origination fees. The state
redemption price at maturity of a Mortgage Loan is the sum of all payments to be
made on such Mortgage Loan other than payments that are treated as qualified
stated interest payments. The accrual of this OID, as described below under
"-- Accrual of Original Issue Discount," will, unless otherwise specified in the
related Prospectus Supplement, utilize the original yield to maturity of the
Senior Certificates calculated based on a reasonable assumed prepayment rate for
the mortgage loans underlying the Senior Certificates (the "Prepayment
Assumption"), and will take into account events that occur during the
calculation period. The Prepayment Assumption will be determined in the manner
prescribed by regulations that have not yet been issued. The legislative history
of the 1986 Act (the "Legislative History") provides, however, that the
regulations will require that the Prepayment Assumption be the prepayment
assumption that is used in determining the offering price of such Certificate.
No representation is made that any Senior Certificate will prepay assumption
contained in the Code literally only applies to debt instruments collateralized
by other debt instruments that are subject to prepayment rather than direct
ownership interest in such debt instruments, such as the Senior Certificates
represent. However, no other legal authority provides guidance with regard to
the proper method for accruing OID on obligations that are subject to
prepayment, and, until further guidance is issued, the Servicer intends to
calculate and report OID under the method described below.
 
     Accrual of Original Issue Discount.  Generally, the owner of a Senior
Certificate must include in gross income the sum of the "daily portions," as
defined below, of the OID on such Senior Certificate for each day on which it
owns such Senior Certificate, including the date of purchase but excluding the
date of disposition. In the case of an original owner, the daily portions of OID
with respect to each component generally will be determined as set forth under
the OID Regulations. A calculation will be made by the Servicer or such other
entity specified in the related Supplement of the portion of OID that accrues
during each successive monthly accrual period (or shorter period from the date
of original issue) that ends on the day in the calendar year corresponding to
each of the Distribution Dates on the Senior Certificates (or the day prior to
each such date). This will be done, in the case of each full month accrual
period, by adding (i) the present value at the end of the accrual period
(determined by using as a discount factor the original yield to maturity of the
respective component under the Prepayment Assumption) of all remaining payments
to be received under the Prepayment Assumption on the respective component and
(ii) any payments received during such accrual period, and subtracting from that
total the "adjusted issue price" of the respective component at the beginning of
such accrual period. The adjusted issue price of a Senior Certificate at the
beginning of the first accrual period is its issue price; the adjusted issue
price of a Senior Certificate at the beginning of a subsequent accrual period is
the adjusted issue price at the beginning of the immediately preceding accrual
period plus the amount of OID allocable to that accrual period reduced by the
amount of any payment made at the end of or during that accrual period. The OID
accruing during such accrual period will then be divided by the number of days
in the period to determine the daily portion of OID for each day in the period.
With respect to an initial accrual period shorter than a full monthly accrual
period, the daily portions of OID must be determined according to an appropriate
allocation under any reasonable method.
 
     Original issue discount generally must be reported as ordinary gross income
as it accrues under a constant interest method that takes into account the
compounding of interest as it accrues rather than when received. However, the
amount of original issue discount includible in the income of a holder of an
obligation is reduced when the obligation is acquired after its initial issuance
at a price greater than the sum of the original issue price and the previously
accrued original issue discount, less prior payments of principal. Accordingly,
if such Mortgage Loans acquired by a Certificateholder are purchased at a price
equal to the then unpaid principal amount of such Mortgage Loan, no original
issue discount attributable to the difference between the issue price and the
original principal amount of such Mortgage Loan (i.e. points) will be includible
by such holder. Other original issue discount on the Mortgage Loans (e.g., that
arising from a "teaser" rate) would still need to be accrued.
 
     Senior Certificates Representing Interests in ARM Loans.  The OID
Regulations do not address the treatment of instruments, which represent
interests in Mortgage Loans with Mortgage Rates which adjust periodically ("ARM
Loans"). Additionally, the IRS has not issued guidance under the Code's coupon
 
                                       55
<PAGE>   124
 
stripping rules with respect to such instruments. In the absence of any
authority, the Servicer will report original issue discount on Senior
Certificates attributable to ARM Loans ("Stripped ARM Obligations") to holders
in a manner it believes is consistent with the rules described above under the
heading "Senior Certificates Representing Interests in Loans Other Than ARM
Loans" and with the OID Regulations. In general, application of these rules may
require inclusion of income on a Stripped ARM Obligation in advance of the
receipt of cash attributable to such income. Further, the addition of interest
deferred by reason of negative amortization to the principal balance of an ARM
Loan may require the inclusion of such amount in the income of the
Certificateholder when such amount accrues. Furthermore, the addition of
Deferred Interest to the Certificate's principal balance will result in
additional income (including possibly original issue discount income) to the
Certificateholder over the remaining life of such Senior Certificates.
 
     Because the treatment of Stripped ARM Obligations is uncertain, investors
are urged to consult their tax advisors regarding how income will be includible
with respect to such Certificates.
 
SALE OR EXCHANGE OF A SENIOR CERTIFICATE
 
     Sale or exchange of a Senior Certificate prior to its maturity will result
in gain or loss equal to the difference, if any, between the amount received,
and the owner's adjusted basis in the Senior Certificate. Such adjusted basis
generally will equal the seller's purchase price for the Senior Certificate,
increased by the original issue discount included in the seller's gross income
with respect to the Senior Certificate, and reduced by principal payments on the
Senior Certificate previously received by the seller. Such gain or loss will be
capital gain or loss to an owner for which a Senior Certificate is a "capital
asset" within the meaning of Code Section 1221, and will be long-term or
short-term depending on whether the Senior Certificate has been owned for the
long-term capital gain holding period (currently more than one year).
 
     Senior Certificates will be "evidences of indebtedness" within the meaning
of Code Section 582(c)(1), so that gain or loss recognized from the sale of a
Senior Certificate by a bank or a thrift institution to which such section
applies will be ordinary income or loss.
 
NON-U.S. PERSONS
 
     Generally, to the extent that a Senior Certificate evidences ownership in
Mortgage Loans that are issued on or before July 18, 1984, interest or original
issue discount paid by the person required to withhold tax under Code Section
1441 or 1442 to (i) an owner that is not a U.S. Person (as defined below), or
(ii) a Senior Certificateholder holding on behalf of an owner that is not a U.S.
Person, will be subject to federal income tax, collected by withholding, at a
rate of 30% or such lower rate as may be provided for interest by an applicable
tax treaty. Accrued original issue discount recognized by the owner on the sale
or exchange of such a Senior Certificate also will be subject to federal income
tax at the same rate. Generally, such payments would not be subject to
withholding to the extent that a Senior Certificate evidences ownership in
Mortgage Loans issued after July 18, 1984 if (i) such Senior Certificateholder
does not actually or constructively own 10 percent or more of the combined
voting power of all classes of equity in the issuer (which for purposes of this
discussion may be defined as the Trust Fund (the "Issuer")); (ii) such Senior
Certificateholder is not a controlled foreign corporation (within the meaning of
Code Section 957) related to the Issuer; and (iii) such Senior Certificateholder
complies with certain identification requirements (including delivery of a
statement, signed by the Senior Certificateholder under penalties of perjury,
certifying that such Senior Certificateholder is not a U.S. Person and providing
the name and address of such Senior Certificateholder).
 
     For purposes of this discussion, a "U.S. Person" means a citizen or
resident of the United States, a corporation or a partnership organized in or
under the laws of the United States, or any political subdivision thereof or an
estate or trust, the income of which, from sources outside the United States, is
includible in gross income for federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States.

INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The Servicer will furnish or make available, within a reasonable time after
the end of each calendar year, to each Certificateholder at any time during such
year, such information as may be deemed necessary or desirable to assist
Certificateholders in preparing their federal income tax returns, or to enable
holders to make such information available to owners or other financial
intermediaries of holders that hold such Certificates as nominees. If a holder,
owner or other recipient of a payment on behalf of an owner fails to supply a
certified taxpayer identification number or if the Secretary of the Treasury
determines that such person has not reported all interest and dividend income
required to be shown on its federal income tax return, 31% backup withholding
may be required with respect to any payments. Any amounts deducted and withheld
from a distribution to a recipient would be allowed as a credit against such
recipient's federal income tax liability.
 
REMIC CERTIFICATES
 
     The Pool relating to a Series of Certificates may elect to be treated as a
REMIC. Qualification as a REMIC requires ongoing compliance with certain
conditions. Although a REMIC is not generally subject to federal income tax
(see, however "Residual Certificates -- Prohibited Transactions"), if a Pool
with respect to which a REMIC election is made fails to comply with one or more
of the ongoing requirements of the Code for REMIC status during any taxable
year, including the implementation of restrictions on the purchase and transfer
of the residual interest in a REMIC as described below under "Residual
Certificates", the Code provides that a Pool will not be treated as a REMIC for
such year and thereafter. In that event, such entity may be taxable as a
separate corporation under Treasury regulations, and the related REMIC
Certificates may not be accorded the status or given the tax treatment described
below. While the Code authorizes the Treasury Department to issue regulations
providing relief in the event of an inadvertent termination of REMIC status, no
such regulations have been issued. Any such relief moreover, may be accompanied
by sanctions, such as the imposition of a corporate tax on all or a portion of
the REMIC's income for the period in which the requirements for such status are
not satisfied. With respect to each such Pool that elects REMIC status, Brown &
Wood will deliver its opinion generally to the effect that, under then existing
law and assuming compliance with all provisions of the related Agreement, such
Pool will qualify as a REMIC and the related Certificates will be considered to
be regular interests ("Regular Certificates") or residual interests ("Residual
Certificates") in the REMIC.
 
     The Supplement for each Series of Certificates will indicate whether the
Pool will make a REMIC election and whether a class of Certificates will be
treated as a regular or residual interest in the REMIC.
 
     In general, with respect to each Series of Certificates for which a REMIC
election is made, (i) Certificates held by a thrift institution taxed as a
"mutual savings bank" or "domestic building and loan association" will represent
interests in "qualifying real property loans" within the meaning of Code Section
593(d)(1); (ii) Certificates held by a thrift institution taxed as a "domestic
building and loan association" will constitute assets described in Code Section
7701(a)(19)(C); (iii) Certificates held by a real estate investment trust will
constitute "real estate assets" within the meaning of Code Section 856(c)(5)(A);
and (iv) interest on Certificates will be considered "interest on obligations
secured by mortgages on real property" within the meaning of Code Section
856(c)(3)(B). If less than 95% of the REMIC's assets are assets qualifying under
any of the foregoing Code sections, the Certificates will be qualifying assets
only to the extent that the REMIC's assets are qualifying assets. In addition,
payments on Mortgage Loans held pending distribution on the REMIC Certificates
will be treated as qualifying real property loans for purposes of Code Section
593(d)(1) and real estate assets for purposes of Code Section 856(c).
 
     Tiered REMIC Structures.  For certain series of Certificates, two separate
elections may be made to treat designated portions of the related Pool as REMICs
(respectively, the "Subsidiary REMIC" and the "Master REMIC") for federal income
tax purposes. Upon the issuance of any such series of Certificates, Brown &
Wood, counsel to the Sponsor, will deliver its opinion generally to the effect
that, assuming compliance with all provisions of the related Pooling and
Servicing Agreement and Trust Agreement, the Subsidiary REMIC and the Master
REMIC will each qualify as a REMIC and the REMIC Certificates issued by the
Subsidiary REMIC and the Master REMIC, respectively, will be considered to
evidence
 
                                       57
<PAGE>   126
 
ownership of Regular Certificates or Residual Certificates in the related REMIC
within the meaning of the REMIC provisions.
 
     Only REMIC Certificates (other than the Residual Certificates in the
Subsidiary REMIC) issued by the Master REMIC will be offered hereunder. The
Subsidiary REMIC and the Master REMIC will be treated as one REMIC solely for
purposes of determining whether the REMIC Certificates will be (i) "qualifying
real property loans" under Section 593(d) of the Code, (ii) "real estate assets"
within the meaning of Section 856(c)(5)(A) of the Code, (iii) "loans secured by
an interest in real property" under Section 7701(a)(19)(C) of the Code and (iv)
whether the income on such Certificates is Interest described in Section
856(c)(3)(B) of the Code.
 
REGULAR CERTIFICATES
 
     General.  Except as otherwise stated in this discussion, Regular
Certificates will be treated for federal income tax purposes as debt instruments
issued by the REMIC and not as ownership interests in the REMIC or its assets.
Moreover, holders of Regular Certificates that otherwise report income under a
cash method of accounting will be required to report income with respect to
Regular Certificates under an accrual method.
 
     Original Issue Discount and Premium.  The Regular Certificates may be
issued with "original issue discount" within the meaning of Code Section
1273(a). Generally, such original issue discount, if any, will equal the
difference between the "stated redemption price at maturity" of a Regular
Certificate and its "issue price." Holders of any class of Certificates issued
with original issue discount will be required to include such original issue
discount in gross income for federal income tax purposes as it accrues, in
accordance with a constant interest method based on the compounding of interest,
as it accrues rather than in accordance with receipt of the interest payments.
The following discussion is based in part on Treasury regulations issued on
January 27, 1994 under Code Sections 1271 through 1273 and 1275 (the "OID
Regulations ") and in part on the provisions of the Tax Reform Act of 1986 (the
"1986 Act"). The holder of a Regular Certificate should be aware, however, that
the OID Regulations do not adequately address certain issues relevant to
prepayable securities, such as the Regular Certificates.
 
     Rules governing original issue discount are set forth in Code Sections 1271
through 1273 and 1275. These rules require that the amount and rate of accrual
of original issue discount be calculated based on a Prepayment Assumption and
prescribe a method for adjusting the amount and rate of accrual of such discount
where the actual prepayment rate differs from the Prepayment Assumption. Under
the Code, the Prepayment Assumption must be determined in the manner prescribed
by regulations which have not yet been issued. The Legislative History provides,
however, that Congress intended the regulations to require that the Prepayment
Assumption be the prepayment assumption that is used in determining the initial
offering price of such Regular Certificates. The Supplement for each Series of
Regular Certificates will specify the Prepayment Assumption to be used for the
purpose of determining the amount and rate of accrual of original issue
discount. No representation is made that the Regular Certificates will prepay at
the Prepayment Assumption or at any other rate.
 
     In general, each Regular Certificate will be treated as a single
installment obligation issued with an amount of original issue discount equal to
the excess of its "stated redemption price at maturity" over its "issue price."
The issue price of a Regular Certificate is the first price at which a
substantial amount of Regular Certificates of that class are sold to the public
(excluding bond houses, brokers, underwriters or wholesalers). The issue price
of a Regular Certificate also includes the amount paid by an initial Regular
Certificateholder for accrued interest that relates to a period prior to the
issue date of the Regular Certificate. The stated redemption price at maturity
of a Regular Certificate includes the original principal amount of the Regular
Certificate, but generally will not include distributions of interest if such
distributions constitute "qualified stated interest." Under the OID Regulations,
qualified stated interest generally means interest payable at a single fixed
rate or qualified variable rate (as described below) provided that such interest
payments are unconditionally payable at intervals of one year or less during the
entire term of the Regular Certificate. Interest is payable at a single fixed
rate only if the rate appropriately takes into account the length of the
interval between payments. Distributions of interest on Regular Certificates
with respect to which
 
                                       58
<PAGE>   127
 
deferred interest will accrue, will not constitute qualified stated interest
payments, in which case the stated redemption price at maturity of such Regular
Certificates includes all distributions of interest as well as principal
thereon.
 
     Where the interval between the issue date and the first Distribution Date
on a Regular Certificate is longer than the interval between subsequent
Distribution Dates, the greater of any original issue discount disregarding the
rate in the first period and any interest foregone during the first period is
treated as the amount by which the stated redemption price of the Regular
Certificate exceeds its issue price for purposes of the de minimis rule
described below. The OID Regulations suggest that all interest on a long first
period Regular Certificate that is issued with non-de minimis OID will be
treated as OID. Where the interval between the issue date and the first
Distribution Date on a Regular Certificate is shorter than the interval between
subsequent Distribution Dates, interest due on the first Distribution Date in
excess of the amount that accrued during the first period would be added to the
Certificate's stated redemption price at maturity. Regular Certificateholders
should consult their own tax advisors to determine the issue price and stated
redemption price at maturity of a Regular Certificate.
 
     Under the de minimis rule, original issue discount on a Regular Certificate
will be considered to be zero if such original issue discount is less than 0.25%
of the stated redemption price at maturity of the Regular Certificate multiplied
by the weighted average maturity of the Regular Certificate. For this purpose,
the weighted average maturity of the Regular Certificate is computed as the sum
of the amounts determined by multiplying the number of full years (i.e.,
rounding down partial years) from the issue date until each distribution in
reduction of stated redemption price at maturity is scheduled to be made by a
fraction, the numerator of which is the amount of each distribution included in
the stated redemption price at maturity of the Regular Certificate and the
denominator of which is the stated redemption price at maturity of the Regular
Certificate. Although currently unclear, it appears that the schedule of such
distributions should be determined in accordance with the assumed rate of
prepayment of the Mortgage Loans and the anticipated reinvestment rate, if any,
relating to the Regular Certificates (the "Prepayment Assumption"). The
Prepayment Assumption with respect to a Series of Regular Certificates will be
set forth in the related Supplement. Holders generally must report de minimis
OID pro rata as principal payments are received, and such income will be capital
gain if the Regular Certificate is held as a capital asset.
 
     Generally, a Regular Certificateholder must include in gross income the
"daily portions," as determined below, of the original issue discount that
accrues on a Regular Certificate for each day the Regular Certificateholder
holds the Regular Certificate, including the purchase date but excluding the
disposition date. In the case of an original holder of a Regular Certificate, a
calculation will be made of the portion of the original issue discount that
accrues during each successive period ("an accrual period") that ends on the day
in the calendar year corresponding to a Distribution Date (or if Distribution
Dates are on the first day or first business day of the immediately preceding
month, interest may be treated as payable on the last day of the immediately
preceding month) and begins on the day after the end of the immediately
preceding accrual period (or on the issue date in the case of the first accrual
period). This will be done, in the case of each full accrual period, by (i)
adding (a) the present value at the end of the accrual period (determined by
using as a discount factor the original yield to maturity of the Regular
Certificates as calculated under the Prepayment Assumption) of all remaining
payments to be received on the Regular Certificate under the Prepayment
Assumption, and (b) any payments included in the stated redemption price at
maturity received during such accrual period, and (ii) subtracting from that
total the "adjusted issue price" of the Regular Certificates at the beginning of
such accrual period. The "adjusted issue price" of a Regular Certificate at the
beginning of the first accrual period is its issue price; the "adjusted issue
price" of a Regular Certificate at the beginning of a subsequent accrual period
is the "adjusted issue price" at the beginning of the immediately preceding
accrual period plus the amount of original issue discount allocable to that
accrual period and reduced by the amount of any payment other than a payment of
qualified stated interest made at the end of or during that accrual period. The
original issue discount accrued during an accrual period will then be divided by
the number of days in the period to determine the daily portion of original
issue discount for each day in the accrual period. The calculation of original
issue discount under the method described above will cause the accrual of
original issue discount to either increase or decrease (but never below zero) in
a given accrual period to reflect the fact that
 
                                       59
<PAGE>   128
 
prepayments are occurring faster or slower than under the Prepayment Assumption.
With respect to an initial accrual period shorter than a full accrual period the
daily portions of original issue discount must be determined according to an
appropriate allocation under any reasonable method.
 
     A subsequent purchaser of a Regular Certificate issued with original issue
discount who purchases the Regular Certificate at a cost less than the remaining
stated redemption price at maturity will also be required to include in gross
income the sum of the daily portions of original issue discount on that Regular
Certificate. In computing the daily portions of original issue discount for such
a purchaser (as well as an initial purchaser that purchases at a price higher
than the adjusted issue price but less than the stated redemption price at
maturity), however, the daily portion is reduced by the amount that would be the
daily portion for such day (computed in accordance with the rules set forth
above) multiplied by a fraction, the numerator of which is the amount, if any,
by which the price paid by such holder for that Regular Certificate exceeds the
following amount: (a) the sum of the issue price plus the aggregate amount of
original issue discount that would have been includible in the gross income of
an original Regular Certificateholder (who purchased the Regular Certificate at
its issue price), (b) less any prior payments included in the stated redemption
price at maturity, and the denominator of which is the sum of the daily portions
for that Regular Certificate for all days beginning on the date after the
purchase date and ending on the maturity date computed under the Prepayment
Assumption. A holder who pays an acquisition premium instead may elect to accrue
OID by treating the purchase as a purchase of original issue.
 
     The IRS recently issued proposed regulations (the "Proposed Contingent
Regulations") governing the calculation of OID on instruments having contingent
interest payments. The Proposed Contingent Regulations, although not effective
until 60 days after finalized, represent the only guidance regarding the views
of the IRS with respect to contingent interest instruments and specifically do
not apply for purposes of calculating OID on debt instruments subject to Code
Section 1272(a)(6), such as the Regular Certificates. 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.
 
     Variable Rate Regular Certificates.  Regular Certificates may provide for
interest based on a variable rate. Interest is treated as payable at a variable
rate and not as contingent interest if, generally, (i) the issue price does not
exceed the original principal balance by more than a specified amount, and (ii)
the compound compounds or is payable at least annually at current values of
certain objective rates measured by or based on lending rate for newly borrowed
funds. The variable interest generally will be qualified stated interest to the
extent it is unconditionally payable at least annually and, to the extent
successive variable rates are used, interest is not significantly accelerated or
deferred.
 
     The amount of OID with respect to a Regular Certificate bearing a variable
rate of interest will accrue in the manner described above under "Original Issue
Discount," by assuming generally that the index used for the variable rate will
remain fixed throughout the term of the Certificate. Approximate adjustments are
made for the actual variable rate.
 
     Although unclear at present, it is anticipated that Regular Certificates
bearing an interest rate that is a weighted average of the net interest rates on
Mortgage Loans will be treated as variable rate certificates. In such case, the
weighted average rates used to compute the initial pass-through rate on the
Regular Certificates will be deemed to be the index in effect through the life
of the Regular Certificates. It is possible, however, that the IRS may treat
some or all of the interest on Regular Certificates with a weighted average rate
as taxable under the rules relating to obligations providing for contingent
payments. Such treatment may affect the timing of income accruals on such
Regular Certificates. Additionally, if some or all of the Mortgage Loans are
subject to "teaser rates" (i.e., the initial rates on the Mortgage Loans are
less than subsequent rates on the Mortgage Loans) the interest paid on some or
all of the Regular Certificates may be subject to accrual using a constant yield
method notwithstanding the fact that such Certificates may not have been issued
with "true" non-de minimis original issue discount.

     Election to Treat All Interest as OID.  The OID Regulations permit a
Certificateholder to elect to accrue all interest, discount (including de
minimis market or original issue discount) and premium in income as interest,
based on a constant yield method for Certificates acquired on or after April 4,
1994. If such an election were to be made with respect to a Regular Certificate
with market discount, the Certificateholder would be deemed to have made an
election to include in income currently market discount with respect to all
other debt instruments having market discount that such Certificateholder
acquires during the year of the election or thereafter. Similarly, a
Certificateholder that makes this election for a Certificate that is acquired a
premium will be deemed to have made an election to amortize bond premium with
respect to all debt instruments having amortizable bond premium with that such
Certificateholder owns or acquires. See "-- Regular Certificates -- Premium"
herein. The election to accrue interest, discount and premium on a constant
yield method with respect to a Certificate cannot be revoked without the consent
of the IRS.
 
     Market Discount.  A purchaser of a Regular Certificate also may be subject
to the market discount provisions of Code Sections 1276 through 1278. Under
these provisions and the OID Regulations "market discount" equals the excess, if
any, of (i) the Regular Certificate's stated principal amount or, in the case of
a Regular Certificate with original issue discount, the adjusted issue price
(determined for this purpose as if the purchaser had purchased such Regular
Certificate from an original holder) over (ii) the price for such Regular
Certificate paid by the purchaser. A Certificateholder that purchases a REMIC
Regular Certificate at a market discount, will recognize gain upon receipt of
each distribution representing stated redemption price. In particular, under
Section 1276 of the Code such a holder generally will be required to allocate
each such principal distribution first to accrued market discount not previously
included in income, and to recognize ordinary income to that extent. A
Certificateholder may elect to include market discount in income currently as it
accrues rather than including it on a deferred basis in accordance with the
foregoing. If made, such election will apply to all market discount bonds
acquired by such Certificateholder on or after the first day of the first
taxable year to which such election applies. In addition, the OID Regulations
permit a Certificateholder using either the accrual or cash method of accounting
to elect to accrue all interest, discount (including de minimis market or
original issue discount) and premium in income as interest, based on a constant
yield method. If such an election were made with respect to a REMIC Regular
Certificate with market discount, the Certificateholder would be deemed to have
made an election to include in income currently market discount with respect to
all other debt instruments having market discount that such Certificateholder
acquires during the year of the election or thereafter. Similarly, a
Certificateholder that makes this election for a Certificate that is acquired at
a premium 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. See "Taxation of Regular
Certificates -- Premium". The election to accrue interest, discount and premium
on a constant yield method with respect to a Certificate is irrevocable.
 
     Market discount with respect to a Regular Certificate will be considered to
be zero if the amount allocable to the Regular Certificate is less than 0.25% of
the Regular Certificate's stated redemption price at maturity multiplied by the
Regular Certificate's weighted average maturity remaining after the date of
purchase. If market discount on a Regular Certificate is considered to be zero
under this rule, the actual amount of market discount must be allocated to the
remaining principal payments on the Regular Certificate and gain equal to such
allocated amount will be recognized when the corresponding principal payment is
made. Treasury regulations implementing the market discount rules have not yet
been issued; therefore, investors should consult their own tax advisors
regarding the application of these rules and the advisability of making any of
the elections allowed under Code Sections 1276 through 1278.
 
     The Code provides that any principal payment (whether a scheduled payment
or a prepayment) or any gain on disposition of a market discount bond acquired
by the taxpayer after October 22, 1986, shall be treated as ordinary income to
the extent that it does not exceed the accrued market discount at the time of
such payment. The amount of accrued market discount for purposes of determining
the tax treatment of subsequent principal payments or dispositions of the market
discount bond is to be reduced by the amount so treated as ordinary income.
 
     The Code also grants authority to the Treasury Department to issue
regulations providing for the computation of accrued market discount on debt
instruments, the principal of which is payable in more than
 
                                       61

one installment. Until such time as regulations are issued by the Treasury,
rules described in the Legislative History will apply. Under those rules, the
holder of a market discount bond may elect to accrue market discount either on
the basis of a constant interest rate or according to one of the following
methods. For Regular Certificates issued with original issue discount, the
amount of market discount that accrues during a period is equal to the product
of (i) the total remaining market discount, multiplied by (ii) a fraction, the
numerator of which is the original issue discount accruing during the period and
the denominator of which is the total remaining original issue discount at the
beginning of the period. For Regular Certificates issued without original issue
discount, the amount of market discount that accrues during a period is equal to
the product of (i) the total remaining market discount, multiplied by (ii) a
fraction, the numerator of which is the amount of stated interest paid during
the accrual period and the denominator of which is the total amount of stated
interest remaining to be paid at the beginning of the period. For purposes of
calculating market discount under any of the above methods in the case of
instruments (such as the Regular Certificates) which provide for payments which
may be accelerated by reason of prepayments of other obligations securing such
instruments, the same Prepayment Assumption applicable to calculating the
accrual of original issue discount will apply.
 
     A holder of a Regular Certificate who acquires such Regular Certificate at
a market discount also may be required to defer, until the maturity date of such
Regular Certificate or its earlier disposition in a taxable transaction, the
deduction of a portion of the amount of interest that the holder paid or accrued
during the taxable year on indebtedness incurred or maintained to purchase or
carry the Regular Certificate in excess of the aggregate amount of interest
(including original issue discount) includible in such holder's gross income for
the taxable year with respect to such Regular Certificate. The amount of such
net interest expense deferred in a taxable year may not exceed the amount of
market discount accrued on the Regular Certificate for the days during the
taxable year on which the holder held the Regular Certificate and, in general,
would be deductible when such market discount is includible in income. The
amount of any remaining deferred deduction is to be taken into account in the
taxable year in which the Regular Certificate matures or is disposed of in a
taxable transaction. In the case of a disposition in which gain or loss is not
recognized in whole or in part any remaining deferred deduction will be allowed
to the extent of gain recognized on the disposition. This deferral rule does not
apply if the Regular Certificateholder elects to include such market discount in
income currently as it accrues on all market discount obligations acquired by
such Regular Certificateholder in that taxable year or thereafter.
 
     Premium.  A purchaser of a Regular Certificate who purchases the Regular
Certificate at a cost (not including accrued qualified stated interest) greater
than its remaining stated redemption price at maturity will be considered to
have purchased the Regular Certificate at a premium, and may elect to amortize
such premium under a constant yield method. It is not clear whether the
Prepayment Assumption would be taken into account in determining the life of the
Regular Certificate for this purpose. However, the Legislative History states
that the same rules that apply to accrual of market discount (which rules
require use of a Prepayment Assumption in accruing market discount with respect
to Regular Certificates without regard to whether such Certificates have
original issue discount) will also apply in amortizing bond premium under Code
Section 171. The Code provides that amortizable bond premium will be allocated
among the interest payments on such Regular Certificates and will be applied as
an offset against such interest payment.
 
     Deferred Interest.  Certain classes of Regular Certificates will provide
for the accrual of interest when one or more ARM Loans are adding interest to
their principal balance by reason of negative amortization ("Deferred
Interest"). Any Deferred Interest that accrues with respect to a class of
Regular Certificates will constitute income to the holders of such Certificates
prior to the time distributions of cash with respect to such Deferred Interest
are made. It is unclear, under the OID Regulations, whether any of the interest
on such Certificates will constitute qualified stated interest or whether all or
a portion of the interest payable on the Certificate must be included in the
stated redemption price at maturity of the Certificate and accounted for as
original issue discount (which could accelerate such inclusion). Interest on
Regular Certificates must in any event be accounted for under an accrual method
by the holders of such Certificates, and therefore applying the latter analysis
may result only in a slight difference in the timing of the inclusion in income
of interest on such Regular Certificates.
 
                                       62
<PAGE>   131
 
     Accrued Interest Certificates.  Certain of the Regular Certificates
("Payment Lag Certificates") may provide for payments of interest based on a
period that corresponds to the interval between Distribution Dates but that ends
prior to each such Distribution Date. The period between the Closing Date for
Payment Lag Certificates and their first Distribution Date may or may not exceed
such interval. Purchasers of Payment Lag Certificates for which the period
between the Closing Date and the first Distribution Date does not exceed such
interval could pay upon purchase of the Regular Certificates accrued interest in
excess of the accrued interest that would be paid if the interest paid on the
Distribution Date were interest accrued from Distribution Date to Distribution
Date. If a portion of the initial purchase price of a Regular Certificate is
allocable to interest that has accrued prior to the issue date ("pre-issuance
accrued interest") and the Regular Certificate provides for a payment of stated
interest on the first payment date, within one year of the issue date, that
equals or exceeds the amount of the pre-issuance accrued interest, then the
Regular Certificates issue price may be computed by subtracting from the issue
price the amount of pre-issuance accrued interest, rather than as an amount
payable on the Regular Certificate. However, it is unclear under this method how
the OID Regulations treat interest on Payment Lag Certificates as described
above. Therefore, in the case of a Payment Lag Certificate, the REMIC intends to
include accrued interest in the issue price and report interest payments made on
the first Distribution Date as interest to the extent such payments represent
interest for the number of days which the Certificateholder has held such
Payment Lag Certificate during the first Accrual Period.
 
     Sale, Exchange or Redemption of Regular Certificates.  If a Regular
Certificate is sold, exchanged, redeemed or retired, the seller will recognize
gain or loss equal to the difference between the amount realized on the sale,
exchange or redemption and the seller's adjusted basis in the Regular
Certificate. Such adjusted basis generally will equal the cost of the Regular
Certificate to the seller, increased by any original issue discount and market
discount included in the seller's gross income with respect to the Regular
Certificate, and reduced (but not below zero) by payments included in the stated
redemption price at maturity previously received by the seller and by any
amortized premium. Similarly, a holder who receives a payment which is part of
the stated redemption price at maturity of a Regular Certificate will recognize
gain equal to the excess, if any, of the amount of the payment over his adjusted
basis in the Regular Certificate. A holder of a Regular Certificate who receives
a final payment which is less than his adjusted basis in the Regular Certificate
will generally recognize a loss. Except as provided in the following paragraph
and as provided under "Market Discount" below, any such gain or loss will be
capital gain or loss, provided that the Regular Certificate is held as a
"capital asset" (generally, property held for investment) within the meaning of
Code Section 1221.
 
     Gain from the sale or other disposition of a Regular Certificate that might
otherwise be capital gain will be treated as ordinary income to the extent that
such gain does not exceed the excess, if any, of (i) the amount that would have
been includible in such holder's income with respect to the Regular Certificate
had income accrued thereon at a rate equal to 110% of the AFR as defined in Code
Section 1274(d) determined as of the date of purchase of such Regular
Certificate, over (ii) the amount actually includible in such holder's income.
Additionally, gain will be treated as ordinary income if the Pool had an
"intention to call" the Regular Certificates prior to maturity. The OID
Regulations provide that the presence of a sinking fund or optimal call does not
give rise to such an intention, and the Seller does not believe such an
intention is otherwise present; however, the application of these rules to REMIC
Certificates is unclear.
 
     Regular Certificates will be "evidences of indebtedness" within the meaning
of Code Section 582(c)(1), so that gain or loss recognized from the sale of a
Regular Certificate by a bank or a thrift institution to which such section
applies will be ordinary income or loss.
 
     Because the regulations described above have not been issued, it is
impossible to predict what effect those regulations might have on the tax
treatment of a Regular Certificate purchased at a discount or premium in the
secondary market.
 
     The Regular Certificate information reports will include a statement of the
adjusted issue price of the Regular Certificate at the beginning of each accrual
period. In addition, the reports will include information necessary to compute
the accrual of any market discount that may arise upon secondary trading of
Regular Certificates. Because exact computation of the accrual of market
discount on a constant yield method would
 
                                       63
<PAGE>   132
 
require information relating to the holder's purchase price which the REMIC may
not have, it appears that this provision will only require information
pertaining to the appropriate proportionate method of accruing market discount.
 
     REMIC Expenses.  As a general rule, all of the expenses of a REMIC will be
taken into account by holders of the Residual Interests. In the case of a
"single class REMIC", however, the expenses and a matching amount of additional
income will be allocated, under temporary Treasury regulations, among the
holders of the Regular Certificates and the holders of the Residual Interests on
a daily basis in proportion to the relative amounts of income accruing to each
Certificateholder on that day. In the case of individuals (or trusts, estates,
or other persons who compute their income in the same manner as individuals) who
own an interest in a Regular Certificate directly or through a pass-through
entity which is required to pass miscellaneous itemized deductions through to
its owners or beneficiaries (e.g. a partnership, an S corporation, or a grantor
trust), such expenses will be deductible only to the extent that such expenses,
plus other "miscellaneous itemized deductions" of the individual, exceed 2% of
such individual's adjusted gross income. In addition, the personal exemptions
and itemized deductions of individuals with adjusted gross incomes above
particular levels are subject to certain limitations which reduce or eliminate
the benefit of such items. The reduction or disallowance of this deduction
coupled with the allocation of additional income may have a significant impact
on the yield of the Regular Certificate to such a Holder. Further, holders
(other than corporations) subject to the alternative minimum tax may not deduct
miscellaneous itemized deductions in determining such holders' alternative
minimum taxable income. In general terms, a single class REMIC is one that
either (i) would qualify, under existing Treasury regulations, as a grantor
trust if it were not a REMIC (treating all interests as ownership interests,
even if they would be classified as debt for federal income tax purposes) or
(ii) is similar to such a trust and is structured with the principal purpose of
avoiding the single class REMIC rules. Unless otherwise stated in the related
Supplement, the expenses of the REMIC will be allocated to holders of the
related Residual Interests in their entirety and not to holders of the related
Regular Certificates.
 
     Non-U.S. Persons.  Generally, payments of interest (including any payment
with respect to accrued original issue discount) on the Regular Certificates to
a Regular Certificateholder who is a non-U.S. Person not engaged in a trade or
business within the United States, will not be subject to federal withholding
tax if (i) such Regular Certificateholder does not actually or constructively
own 10 percent or more of the combined voting power of all classes of equity in
the issuer (which for purposes of this discussion may be defined as the Pool or
the beneficial owners of the related Residual Certificates (the "Issuer")); (ii)
such Regular Certificateholder is not a controlled foreign corporation (within
the meaning of Code Section 957) related to the Issuer; and (iii) such Regular
Certificateholder complies with certain identification requirements (including
delivery of a statement, signed by the Regular Certificateholder under penalties
of perjury, certifying that such Regular Certificateholder is a foreign person
and providing the name and address of such Regular Certificateholder). If a
Regular Certificateholder is not exempt from withholding, distributions of
interest, including distributions in respect of accrued original issue discount,
such holder may be subject to a 30% withholding tax, subject to reduction under
any applicable tax treaty.
 
     Regular Certificateholders who are non-U.S. Persons and persons related to
such holders should not acquire any Residual Certificates, and Residual
Certificateholders and persons related to Residual Certificateholders should not
acquire any Regular Certificates without consulting their tax advisors as to the
possible adverse tax consequences of such acquisition.
 
     Information Reporting and Backup Withholding.  The Servicer will furnish or
make available, within a reasonable time after the end of each calendar year, to
each Regular Certificateholder at any time during such year, such information as
may be deemed necessary or desirable to assist Regular Certificateholders in
preparing their federal income tax returns, or to enable holders to make such
information available to owners or other financial intermediaries of holders
that hold such Regular Certificates as nominees. If a holder, owner or other
recipient of a payment on behalf of an owner fails to supply a certified
taxpayer identification number or if the Secretary of the Treasury determines
that such person has not reported all interest and dividend income required to
be shown on its federal income tax return, 31% backup withholding may be
required with respect to any payments.
 
                                       64
<PAGE>   133
 
     Any amounts deducted and withheld from a distribution to a recipient would
be allowed as a credit against such recipient's federal income tax liability.
 
RESIDUAL CERTIFICATES
 
     Allocation of the Income of the REMIC to the Residual Certificates.  The
REMIC will not be subject to federal income tax except with respect to income
from prohibited transactions and certain other transactions. See "Prohibited
Transactions and Other Taxes" herein. Instead, each original holder of a
Residual Certificate will report on its federal income tax return, as ordinary
income, its share of the taxable income of the REMIC for each day during the
taxable year on which such holder owns any Residual Certificates. The taxable
income of the REMIC for each day will be determined by allocating the taxable
income of the REMIC for each calendar quarter ratably to each day in the
quarter. Such a holder's share of the taxable income of the REMIC for each day,
will be based on the portion of the outstanding Residual Certificates that such
holder owns on that day. The taxable income of the REMIC will be determined
under an accrual method and will be taxable to the Residual Certificateholders
without regard to the timing or amounts of cash distributions by the REMIC.
Ordinary income derived from Residual Certificates will be "portfolio income"
for purposes of the taxation of taxpayers subject to the limitations on the
deductibility of "passive losses." As residual interests, the Residual
Certificates will be subject to tax rules, described below, that differ from
those that would apply if the Residual Certificates were treated for federal
income tax purposes as direct ownership interests in the Certificates, or as
debt instruments issued by the REMIC.
 
     A Residual Certificateholder may be required to include taxable income from
the Residual Certificate in excess of the cash distributed. For example, a
structure where principal distributions are made serially on regular interests
(that is, a fast-pay, slow-pay structure) may generate such a mismatching of
income and cash distributions (that is, "phantom income"). This mismatching may
be caused by the use of certain required tax accounting methods by the REMIC,
variations in the prepayment rate of the underlying Mortgage Loans and certain
other factors. Depending upon the structure of a particular transaction, the
aforementioned factors may significantly reduce the after-tax yield of a
Residual Certificate to a Residual Certificateholder. Investors should consult
their own tax advisors concerning the federal income tax treatment of a Residual
Certificate and the impact of such tax treatment on the after-tax yield of a
Residual Certificate.
 
     A subsequent Residual Certificateholder also will report on its federal
income tax return amounts representing a daily share of the taxable income of
the REMIC for each day that such Residual Certificateholder owns such Residual
Certificate. Those daily amounts generally would equal the amounts that would
have been reported for the same days by an original Residual Certificateholder,
as described above. The Legislative History indicates that certain adjustments
may be appropriate to reduce (or increase) the income of a subsequent holder of
a Residual Certificate that purchased such Residual Certificate at a price
greater than (or less than) the adjusted basis (see "Sales of Residual
Certificates" below) such Residual Certificate would have in the hands of an
original Residual Certificateholder. It is not clear, however, whether such
adjustments will in fact be permitted or required and, if so, how they would be
made.
 
     Taxable Income of the REMIC Attributable to Residual Interests.  The
taxable income of the REMIC will reflect a netting of (i) the income from the
Mortgage Loans and the REMIC's other assets, and (ii) the deductions allowed to
the REMIC for interest and original issue discount on the Regular Certificates
and, except as described below under "Non-Interest Expenses of the REMIC," other
expenses.
 
     For purposes of determining its taxable income, the REMIC will have an
initial aggregate tax basis in its assets equal to the sum of the issue prices
of the Regular and Residual Certificates (or, if a class of Certificates is not
sold initially, their fair market values). Such aggregate basis will be
allocated among the Mortgage Loans and other assets of the REMIC in proportion
to their respective fair market values. A Mortgage Loan will be deemed to have
been acquired with discount or premium to the extent that the REMIC's basis
therein is less than or greater than its principal balance, respectively. Any
such discount (whether market discount or original issue discount) will be
includible in the income of the REMIC as it accrues, in advance of receipt of
the cash attributable to such income, under a method similar to the method
described above for accruing original issue discount on the Regular
Certificates. The REMIC expects to elect under Code Section 171 to
 
                                       65
<PAGE>   134
 
amortize any premium on the Mortgage Loans. Premium on any Mortgage Loan to
which such election applies would be amortized under a constant yield method. It
is not clear whether the yield of a Mortgage Loan would be calculated for this
purpose based on scheduled payments or taking account of the Prepayment
Assumption. Additionally, such an election would not apply to any Mortgage Loan
originated on or before September 27, 1985. Instead, premium on such a Mortgage
Loan would be allocated among the principal payments thereon and would be
deductible by the REMIC as those payments become due.
 
     The REMIC will be allowed a deduction for interest and original issue
discount on the Regular Certificates. The amount and method of accrual of
original issue discount will be calculated for this purpose in the same manner
as described above with respect to Regular Certificates (except that the 0.25%
per annum de minimis rule and adjustments for subsequent holders described
therein will not apply).
 
     A Residual Certificateholder will not be permitted to amortize the cost of
the Residual Certificate as an offset to its share of the REMIC's taxable
income. However, that taxable income will not include cash received by the REMIC
that represents a recovery of the REMIC's basis in its assets, and, as described
above, the issue price of the Residual Certificates will be added to the issue
price of the Regular Certificates in determining the REMIC's initial basis in
its assets. See "Sales of Residual Certificates" herein. For a discussion of
possible adjustments to income of a subsequent holder of a Residual Certificate
to reflect any difference between the actual cost of such Residual Certificate
to such holder and the adjusted basis such Residual Certificate would have in
the hands of an original Residual Certificateholder, see "Allocation of the
Income of the REMIC to the Residual Certificates" above.
 
     Net Losses of the REMIC.  The REMIC will have a net loss for any calendar
quarter in which its deductions exceed its gross income. Such net loss would be
allocated among the Residual Certificateholders in the same manner as the
REMIC's taxable income. The net loss allocable to any Residual Certificate will
not be deductible by the holder to the extent that such net loss exceeds such
holder's adjusted basis in such Residual Certificate. Any net loss that is not
currently deductible by reason of this limitation may be used by such Residual
Certificateholder to offset its share of the REMIC's taxable income in future
periods (but not otherwise). The ability of Residual Certificateholders that are
individuals or closely held corporations to deduct net losses may be subject to
additional limitations under the Code.
 
     Non-Interest Expenses of the REMIC.  As a general rule, the REMIC's taxable
income will be determined in the same manner as if the REMIC were an individual.
However, all or a portion of the REMIC's servicing, administrative and other
non-interest expenses will be allocated as a separate item to Residual
Certificateholders that are "pass-through interest holders." Such a holder would
be required to add its allocable share, if any, of such expenses to its gross
income and to treat the same amount as an item of investment expense. An
individual would generally be allowed a deduction for such an expense item only
as a miscellaneous itemized deduction subject to the limitations under Code
Section 67. That section allows such deduction only to the extent that in the
aggregate all such expenses exceed two percent of an individual's adjusted gross
income. The REMIC is required to report to each pass-through interest holder and
to the IRS such holder's allocable share, if any, of the REMIC's non-interest
expenses. The term "pass-through interest holder" generally refers to
individuals, entities taxed as individuals and certain pass-through entities,
but does not include real estate investment trusts. Residual Certificateholders
that are "pass-through interest holders" should consult their own tax advisors
about the impact of these rules on an investment in the Residual Certificates.
See "Non-Interest Expenses of the REMIC" under "Regular Certificates" above.
 
     Deferred Interest.  Any Deferred Interest that accrues with respect to any
ARM Loans held by the REMIC will constitute income to the REMIC and will be
treated in a manner similar to the Deferred Interest that accrues with respect
to Regular Certificates as described above under "Regular
Certificates -- Deferred Interest."
 
     Excess Inclusions.  A portion of the income on a Residual Certificate
(referred to in the Code as an "excess inclusion") for any calendar quarter
will, with an exception discussed below for certain thrift institutions, be
subject to federal income tax in all events. Thus, for example, an excess
inclusion (i) may not, except as described below, be offset by any unrelated
losses or loss carryovers of a Residual Certificateholder; (ii) will be treated
as "unrelated business taxable income" within the meaning of Code Section 512 if
the
 
                                       66
<PAGE>   135
 
Residual Certificateholder is a pension fund or any other organization that is
subject to tax only on its unrelated business taxable income (see "Tax-Exempt
Investors" below); and (iii) is not eligible for any reduction in the rate of
withholding tax in the case of a Residual Certificateholder that is a foreign
investor. See "Non-U.S. Persons" below. The exception for thrift institutions is
available only to the institution holding the Residual Certificate, and not to
any affiliate of the institution, unless the affiliate is a subsidiary all the
stock of which, and substantially all the indebtedness of which, is held by the
institution, and which is organized and operated exclusively in connection with
the organization and operation of one or more REMICs.
 
     Except as discussed in the following paragraph, with respect to any
Residual Certificateholder, the excess inclusion for any calendar quarter is the
excess, if any, of (i) the income of such Residual Certificateholder for that
calendar quarter from its Residual Certificate over (ii) the sum of the "daily
accruals" (as defined below) for all days during the calendar quarter on which
the Residual Certificateholder holds such Residual Certificate. For this
purpose, the daily accruals with respect to a Residual Certificate are
determined by allocating to each day in the calendar quarter its ratable portion
of the product of the "adjusted issue price" (as defined below) of the Residual
Certificate at the beginning of the calendar quarter and 120 percent of the
"Federal long-term rate" in effect at the time the Residual Certificate is
issued. For this purpose, the "adjusted issue price" of a Residual Certificate
at the beginning of any calendar quarter equals the issue price of the Residual
Certificate, increased by the amount of daily accruals for all prior quarters,
and decreased (but not below zero) by the aggregate amount of payments made on
the Residual Certificate before the beginning of such quarter. The "Federal
long-term rate" is an average of current yields on Treasury securities with a
remaining term of greater than nine years, computed and published monthly by the
IRS.
 
     As an exception to the general rule described above, the Treasury
Department has authority to issue regulations that would treat the entire amount
of income accruing on a Residual Certificate as an excess inclusion if the
Residual Certificates in the aggregate are considered not to have "significant
value." Under the REMIC Regulations, Residual Certificateholders that are thrift
institutions described in Code Section 593 can offset excess inclusions with
unrelated deductions and net operating losses provided the Residual Certificates
have "significant value". For purposes of applying this rule, thrift
institutions that are members of an affiliated group filing a consolidated
return, together with their subsidiaries formed to issue REMICs, are treated as
separate corporations. Residual Certificates have "significant value" if: (i)
the Residual Certificates have an aggregate issue price that is at least equal
to 2% of the aggregate issue price of all Residual Certificates and Regular
Certificates with respect to the REMIC and (ii) the anticipated weighted average
life of the Residual Certificates is at least 20% of the anticipated weighted
average life of the REMIC. The anticipated weighted average life of the REMIC is
based on the anticipated principal payments to be received with respect to the
Regular Certificates (using the Prepayment Assumption), except that all
anticipated distributions are to be used if the Regular Certificate is not
entitled to any principal payments or is entitled to a disproportionately small
portion relative to interest payments thereon and all anticipated distributions
to the Residual Certificate and the weighted average life of the Residual
Certificate is based on all anticipated distribution to the Residual
Certificate. The principal amount will be considered disproportionately small if
the issue price of the Regular Certificates exceeds 125% of their initial
principal amount. Finally, an ordering rule under the REMIC Regulations provides
that a thrift institution may only offset its excess inclusion income with
deductions after it has first applied its deductions against income that is not
excess inclusion income.
 
     In the case of any Residual Certificates held by a real estate investment
trust, the aggregate excess inclusions with respect to such Residual
Certificates, reduced (but not below zero) by the real estate investment trust
taxable income (within the meaning of Code Section 857(b)(2), excluding any net
capital gain), will be allocated among the shareholders of such trust in
proportion to the dividends received by such shareholders from such trust, and
any amount so allocated will be treated as an excess inclusion with respect to a
Residual Certificate as if held directly by such shareholder. Regulated
investment companies, common trust funds, and certain cooperatives are subject
to similar rules.
 
     Payments.  Any payment made on a Residual Certificate to a Residual
Certificateholder will be treated as a non-taxable return of capital to the
extent it does not exceed the Residual Certificateholder's adjusted
 
                                       67
<PAGE>   136
 
basis in such Residual Certificate. To the extent a distribution exceeds such
adjusted basis, it will be treated as gain from the sale of the Residual
Certificate.
 
     Sale or Exchange of Residual Certificates.  If a Residual Certificate is
sold or exchanged, the seller will generally recognize gain or loss equal to the
difference between the amount realized on the sale or exchange and its adjusted
basis in the Residual Certificate (except that the recognition of loss may be
limited under the "wash sale" rules described below). A holder's adjusted basis
in a Residual Certificate generally equals the cost of such Residual Certificate
to such Residual Certificateholder, increased by the taxable income of the REMIC
that was included in the income of such Residual Certificateholder with respect
to such Residual Certificate, and decreased (but not below zero) by the net
losses that have been allowed as deductions to such Residual Certificateholder
with respect to such Residual Certificate and by the distributions received
thereon by such Residual Certificateholder. In general, any such gain or loss
will be capital gain or loss provided the Residual Certificate is held as a
capital asset. However, Residual Certificates will be "evidences of
indebtedness" within the meaning of Code Section 582(c)(1), so that gain or loss
recognized from sale of a Residual Certificate by a bank or thrift institution
to which such section applies would be ordinary income or loss.
 
     Except as provided in Treasury regulations, if the seller of a Residual
Certificate reacquires such Residual Certificate, or acquires any other Residual
Certificate, any residual interest in another REMIC or similar interest in a
"taxable mortgage pool" (as defined in Code Section 7701(i)) during the period
beginning six months before, and ending six months after, the date of such sale,
such sale will be subject to the "wash sale" rules of Code Section 1091. In that
event, any loss realized by the Residual Certificateholder on the sale will not
be deductible, but, instead, will increase such Residual Certificateholder's
adjusted basis in the newly acquired asset.
 
     Mark to Market Rules.  Prospective purchasers of a Residual Certificate
should be aware that on December 18, 1993, the Internal Revenue Service released
temporary regulations (the "Temporary Regulations") relating to the requirement
that a securities dealer mark to market securities held for sale to customers.
This mark-to-market requirement applies to all securities of a dealer, except to
the extent that the dealer has specifically identified a security as held for
investment. The Temporary Regulations provide that, for purposes of this
mark-to-market requirement, a "negative value" Residual Certificate is not
treated as a security and thus may not be marked to market. In general, a
Residual Certificate has negative value if, as of the date a taxpayer acquires
the Residual Certificate, the present value of the tax liabilities associated
with holding the Residual Certificate exceeds the sum of (i) the present value
of the expected future distributions on the Residual Certificate, and (ii) the
present value of the anticipated tax savings associated with holding the
Residual Certificate as the REMIC generates losses. The amounts and present
values of the anticipated tax liabilities, expected future distributions and
anticipated tax savings are all to be determined using (i) the prepayment and
reinvestment assumptions adopted under Section 1272(a)(6), or that would have
been adopted had the REMIC's regular interests been issued with original issue
discount, (ii) any required or permitted clean up calls, or required qualified
liquidation, provided for in the REMIC's organizational documents and (iii) a
discount rate equal to the "applicable Federal rate" (as specified in Section
1274(d)(1)), that would apply to a debt instrument issued on the date of
acquisition of the Residual Certificate. The Temporary Regulations apply to
taxable years ending on or after December 31, 1993. Prospective purchasers of a
Residual Certificate should consult their tax advisors regarding the possible
application of the Temporary Regulations.
 
     On January 3, 1995, the IRS released proposed regulations under Code
Section 475 (the "Proposed Mark-to-Market Regulations"). The Proposed
Mark-to-Market Regulations provide that any REMIC Residual Interest acquired
after January 3, 1995 cannot be marked to market, regardless of the value of
such REMIC Residual Interest. The Temporary Regulations described above still
apply to any REMIC Residual Interest acquired on or prior to January 3, 1995.
Thus, holders of positive value REMIC Residual Interests acquired on or prior to
January 3, 1995 may continue to mark such residual interests to market for the
entire economic life of such interests.

PROHIBITED TRANSACTIONS AND OTHER TAXES
 
     The REMIC is subject to a tax at a rate equal to 100 percent of the net
income derived from "prohibited transactions." In general, a prohibited
transaction means the disposition of a Mortgage Loan other than pursuant to
certain specified exceptions, the receipt of investment income from a source
other than a Mortgage Loan or certain other permitted investments, or the
disposition of an asset representing a temporary investment of payments on the
Mortgage Loans pending payment on the Residual Certificates or Regular
Certificates. In addition, the assumption of a Mortgage Loan by a subsequent
purchaser could cause the REMIC to recognize gain, which would also be subject
to the 100 percent tax on prohibited transactions.
 
     In addition, certain contributions to a REMIC made after the Closing Date
could result in the imposition of a tax on the REMIC equal to 100% of the value
of the contributed property.
 
     It is not anticipated that the REMIC will engage in any prohibited
transactions or receive any contributions subject to the contributions tax.
However, in the event that the REMIC is subject to any such tax, unless
otherwise disclosed in the related Supplement, such tax would be borne first by
the Residual Certificateholders, to the extent of amounts distributable to them,
and then by the Servicer.
 
LIQUIDATION AND TERMINATION
 
     If the REMIC adopts a plan of complete liquidation, within the meaning of
Code Section 860F(a)(4)(A)(i), which may be accomplished by designating in the
REMIC's final tax return a date on which such adoption is deemed to occur, and
sells all of its assets (other than cash) within a 90-day period beginning on
such date, the REMIC will recognize no gain or loss on the sale of its assets,
provided that the REMIC credits or distributes in liquidation all of the sale
proceeds plus its cash (other than the amounts retained to meet claims) to
holders of Regular and Residual Certificates within the 90-day period.
 
     The REMIC will terminate shortly following the retirement of the Regular
Certificates. If a Residual Certificateholder's adjusted basis in the Residual
Certificate exceeds the amount of cash distributed to such Residual
Certificateholder in final liquidation of its interest, then, although the
matter is not entirely free from doubt, it would appear that the Residual
Certificateholder would be entitled to a loss equal to the amount of such
excess. It is unclear whether such a loss, if allowed, will be a capital loss or
an ordinary loss.
 
ADMINISTRATIVE MATTERS
 
     Solely for the purpose of the administrative provisions of the Code, the
REMIC will be treated as a partnership and the Residual Certificateholders will
be treated as the partners thereof; however, under Temporary Regulations if
there is at no time during the taxable year more than one Residual
Certificateholder, a REMIC shall not be subject to the rules of Subchapter C of
chapter 63 of the Code, relating to the treatment of Partnership items for a
taxable year. Accordingly, the REMIC will file an annual tax return on Form
1066, U.S. Real Estate Mortgage Investment Conduit Income Tax Return. In
addition, certain other information will be furnished quarterly to each Residual
Certificateholder who held such Residual Certificate on any day in the previous
calendar quarter.
 
     Each Residual Certificateholder is required to treat items on its return
consistently with their treatment on the REMIC's return, unless the Residual
Certificateholder either files a statement identifying the inconsistency or
establishes that the inconsistency resulted from incorrect information received
from the REMIC. The IRS may assert a deficiency resulting from a failure to
comply with the consistency requirement without instituting an administrative
proceeding at the REMIC level. The REMIC does not intend to register as a tax
shelter pursuant to Code Section 6111 because it is not anticipated that the
REMIC will have a net loss for any of the first five taxable years of its
existence. Any person that holds a Residual Certificate as a nominee for another
person may be required to furnish the REMIC, in a manner to be provided in
Treasury regulations, with the name and address of such person and other
information.

TAX-EXEMPT INVESTORS
 
     Any Residual Certificateholder that is a pension fund or other entity that
is subject to federal income taxation only on its "unrelated business taxable
income" within the meaning of Code Section 512 will be subject to such tax on
that portion of the distributions received on a Residual Certificate that is
considered an "excess inclusion." See "Excess Inclusions" herein.
 
NON-U.S. PERSONS
 
     Non-U.S. Persons.  Amounts paid to Residual Certificateholders who are not
U.S. Persons (see "Regular Certificates -- Non-U.S. Persons") are treated as
interest for purposes of the 30% (or lower treaty rate) United States
withholding tax. Amounts distributed to Residual Holders should qualify as
"portfolio interest," subject to the conditions described in "Regular
Certificates" above, but only to the extent that the Mortgage Loans were
originated after July 18, 1984. Furthermore, the rate of withholding on any
income on a Residual Certificate that is an excess inclusion will not be subject
to reduction under any applicable tax treaties. See "Residual
Certificates -- Excess Inclusions." If the portfolio interest exemption is
unavailable, such amount will be subject to United States withholding tax when
paid or otherwise distributed (or when the Residual Certificate is disposed of)
under rules similar to those for withholding upon disposition of debt
instruments that have original issue discount. The Code, however, grants the
Treasury Department authority to issue regulations requiring that those amounts
be taken into account earlier than otherwise provided where necessary to prevent
avoidance of tax (for example, where the Residual Certificates do not have
significant value). See "Residual Certificates -- Excess Inclusions." If the
amounts paid to Residual Certificateholders that are not U.S. persons are
effectively connected with their conduct of a trade or business within the
United States, the 30% (or lower treaty rate) withholding will not apply.
Instead, the amounts paid to such non-U.S. Person will be subject to U.S.
federal income taxation at regular graduated rates.
 
     For this purpose, a "U.S. Person" includes a citizen or resident of the
United States, a corporation, partnership or other entity created or organized
under the laws of the United States or any political subdivision thereof, or an
estate or trust whose income from sources without the United States is
includible in gross income for United States federal income tax purposes
regardless of its connection with the conduct of a trade or business in the
United States.
 
     Regular Certificateholders and persons related to such holders should not
acquire any Residual Certificates, and Residual Certificateholders and persons
related to Residual Certificateholders should not acquire any Regular
Certificates without consulting their tax advisors as to the possible adverse
tax consequences of doing so.
 
TAX-RELATED RESTRICTIONS ON TRANSFER
 
     An entity may not qualify as a REMIC unless there are reasonable
arrangements designed to ensure that residual interests in such entity are not
held by "disqualified organizations" (as defined below). Further, a tax is
imposed on the transfer of a residual interest in a REMIC to a "disqualified
organization." The amount of the tax equals the product of (A) an amount (as
determined under regulations) equal to the present value of the total
anticipated "excess inclusions" with respect to such interest for periods after
the transfer, and (B) the highest marginal federal income tax rate applicable to
corporations. The tax is imposed on the transferor unless the transfer is
through an agent (including a broker or other middlemen) for a disqualified
organization, in which event the tax is imposed on the agent. The person
otherwise liable for the tax shall be relieved of liability for the tax if the
transferee furnished to such person an affidavit that the transferee is not a
disqualified organization and, at the time of the transfer, such person does not
have actual knowledge that the affidavit is false. A "disqualified organization"
means (A) the United States, any State, possession, or political subdivision
thereof, any foreign government, any international organization, or any agency
or instrumentality of any of the foregoing (provided that such term does not
include an instrumentality if all its activities are subject to tax and, except
for FHLMC, a majority of its board of directors is not selected by any such
governmental agency), (B) any organization (other than certain farmers'
cooperatives) generally exempt
 
                                       70
<PAGE>   139
 
from federal income taxes unless such organization is subject to the tax on
"unrelated business taxable income" and (C) a rural electric or telephone
cooperative.
 
     A tax is imposed on a "pass-through entity" (as defined below) holding a
residual interest in a REMIC if at any time during the taxable year of the
pass-through entity a disqualified organization is the record holder of an
interest in such entity. The amount of the tax is equal to the product of (A)
the amount of excess inclusions for the taxable year allocable to the interest
held by the disqualified organization, and (B) the highest marginal federal
income tax rate applicable to corporations. The pass-through entity otherwise
liable for the tax, for any period during which the disqualified organization is
the record holder of an interest in such entity, will be relieved of liability
for the tax if such record holder furnishes to such entity an affidavit that
such record holder is not a disqualified organization and, for such period, the
pass-through entity does not have actual knowledge that the affidavit is false.
For this purpose, a "pass-through entity" means (i) a regulated investment
company, real estate investment trust or common trust fund, (ii) a partnership,
trust or estate and (iii) certain cooperatives. Except as may be provided in
Treasury regulations, any person holding an interest in a pass-through entity as
a nominee for another will, with respect to such interest, be treated as a
pass-through entity. The tax on pass-through entities is generally effective for
periods after March 31, 1988, except that in the case of regulated investment
companies, real estate investment trusts, common trust funds and publicly-traded
partnerships the tax shall apply only to taxable years of such entities
beginning after December 31, 1988.
 
     In order to comply with these rules, the Agreement will provide that no
record or beneficial ownership interest in a Residual Certificate may be,
directly or indirectly, purchased, transferred or sold without the express
written consent of the Servicer. The Servicer will grant such consent to a
proposed transfer only if it receives the following: (i) an affidavit from the
proposed transferee to the effect that it is not a disqualified organization and
is not acquiring the Residual Certificate as a nominee or agent for a
disqualified organization, and (ii) a covenant by the proposed transferee to the
effect that the proposed transferee agrees to be bound by and to abide by the
transfer restrictions applicable to the Residual Certificate.
 
     Any attempted transfer or pledge in violation of the transfer restrictions
shall be absolutely null and void and shall vest no rights in any purported
transferee. Investors in Residual Certificates are advised to consult their own
tax advisors with respect to transfers of the Residual Certificates and, in
addition, pass-through entities are advised to consult their own tax advisors
with respect to any tax which may be imposed on a pass-through entity.
 
     Noneconomic Residual Certificates.  The REMIC Regulations disregard, for
federal income tax purposes, any transfer of a Noneconomic Residual Certificate
to a "U.S. Person," as defined in the following section of this discussion,
unless no significant purpose of the transfer is to enable the transferor to
impede the assessment or collection of tax. A Noneconomic Residual Certificate
is any Residual Certificate (including a Residual Certificate with a positive
value at issuance) unless, at the time of transfer, taking into account the
Prepayment Assumption, (i) the present value of the expected future
distributions on the Residual Certificate at least equals the product of the
present value of the anticipated excess inclusions and the highest corporate
income tax rate in effect for the year in which the transfer occurs and (ii) the
transferor reasonably expects that the transferee will receive distributions
from the REMIC at or after the time at which taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes. A
significant purpose to impede the assessment or collection of tax exists if the
transferor, at the time of the transfer, either knew or should have known that
the transferee would be unwilling or unable to pay taxes due on its share of the
taxable income of the REMIC. A transferor is presumed not to have such knowledge
if (i) the transferor conducted a reasonable investigation of the transferee and
(ii) the transferee acknowledges to the transferor that the residual interest
may generate tax liabilities in excess of the cash flow and the transferee
represents that it intends to pay such taxes associated with the residual
interest as they become due. If a transfer of a Noneconomic Residual Certificate
is disregarded, the transferor would continue to be treated as the owner of the
Residual Certificate and would continue to be subject to tax on its allocable
portion of the net income of the REMIC.
 
                                       71
<PAGE>   140
 
     Foreign Investors.  The REMIC Regulations provide that the transfer of a
Residual Certificate that has a "tax avoidance potential" to a "foreign person"
will be disregarded for federal income tax purposes. This rule appears to apply
to a transferee who is not a "U.S. Person", as defined below, unless such
transferee's income in respect of the Residual Certificate is effectively
connected with the conduct of a United States trade or business. A Residual
Certificate is deemed to have a tax avoidance potential unless, at the time of
transfer, the transferor reasonably expects that the REMIC will distribute to
the transferee amounts that will equal at least 30 percent of each excess
inclusion, and that such amounts will be distributed at or after the time the
excess inclusion accrues and not later than the end of the calendar year
following the year of accrual. If the non-U.S. Person transfers the Residual
Certificate to a U.S. Person, the transfer will be disregarded, and the foreign
transferor will continue to be treated as the owner, if the transfer has the
effect of allowing the transferor to avoid tax on accrued excess inclusions. The
provisions in the REMIC Regulations regarding transfers of Residual Certificates
that have tax avoidance potential to foreign persons are effective for all
transfers after June 30, 1992. Until further guidance is issued concerning the
treatment of Residual Certificates held by non-U.S. Persons, the Pooling and
Servicing Agreement will provide that no record or beneficial ownership interest
in a Residual Certificate may be, directly or indirectly, transferred to a
non-U.S. Person unless such person provides the Trustee with a duly completed
I.R.S. Form 4224 and the Trustee consents to such transfer in writing.
 
     For purposes of this discussion, a "U.S. Person" means a citizen or
resident of the United States, or any political subdivision thereof, or an
estate or trust, the income of which, from sources outside the United States, is
includible in gross income for federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States.
 
                            STATE TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described in "Certain
Federal Income Tax Considerations", 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 advisors with respect to the various tax
consequences of investments in the Certificates.
 
                             PLANS OF DISTRIBUTION
 
     Certificates are being offered hereby in Series through one or more of the
various methods described below.
 
     The Sponsor intends that Certificates will be offered through the following
methods from time to time and that offerings may be made concurrently through
more than one of these methods or that an offering of a particular Series of
Certificates may be made through a combination of two or more of these methods.
Such methods are as follows:
 
          1. By negotiated firm commitment underwriting and public offering by
     an underwriter specified in the related Supplement;
 
          2. By agency placements through one or more placement agents specified
     in the related Supplement primarily with institutional investors and
     dealers; and
 
          3. Through offerings by the Sponsor.
 
     A Supplement for each Series will describe the method of offering being
used for that Series and either the price at which such Series is being offered,
the nature and amount of any underwriting discounts or additional compensation
to such underwriters and the proceeds of the offering to the Sponsor, or the
method by which the price at which the underwriters will sell the Certificates
will be determined. A firm commitment underwriting and public offering by
underwriters may be done through underwriting syndicates led by one or more
managing underwriters or through one or more underwriters acting alone. The
managing underwriter or
 
                                       72
<PAGE>   141
 
underwriters with respect to the offer and sale of a particular Series of
Certificates will be set forth on the cover of the Supplement relating to such
Series and the members of the underwriting syndicate, if any, will be named in
such Supplement. The firms acting as underwriters with respect to the
Certificates may include NationsBanc Capital Markets, Inc., an affiliate of the
Sponsor. If such firm is not named in the Supplement, such firm will not be a
party to the Underwriting Agreement in respect of such Certificates, will not be
purchasing any such Certificates from the Sponsor and will have no direct or
indirect participation in the underwriting of such Certificates, although such
firm may participate in the distribution of such Certificates under
circumstances entitling it to a dealer's commission. Each Supplement for an
underwritten offering will also contain information regarding the nature of the
underwriters' obligations, any material relationships between the Sponsor and
any underwriter, and, where appropriate, information regarding any discounts or
concessions to be allowed or reallowed to dealers or others and any arrangements
to stabilize the market for the Certificates so offered. In a firm commitment
underwritten offering, the underwriters will be obligated to purchase all of the
Certificates of such Series if any such Certificates are purchased. Certificates
may be acquired by the underwriters for their own accounts and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. In connection with the sale of the Certificates,
underwriters may receive compensation from the Sponsor or from purchasers of
Certificates in the form of discounts, concessions or commissions. The related
Supplement will describe any such compensation paid by the Sponsor.
 
     In underwritten offerings, the underwriters and agents may be entitled,
under agreements entered into with the Sponsor, to indemnification by the
Sponsor against certain civil liabilities, including liabilities under the
Securities Act, or to contribution with respect to payments which such
underwriters or agents may be required to make in respect thereof.
 
     If a Series is offered otherwise than through underwriters, the Supplement
relating thereto will contain information regarding the nature of such offering
and any agreements to be entered into between the Sponsor and purchasers of
Certificates of such Series. It is contemplated that NationsBanc Capital
Markets, Inc. will act as a placement agent on behalf of the Sponsor in such
offerings of a Series of Certificates. If NationsBanc Capital Markets, Inc. does
act as placement agent in the sale of Certificates, it will receive a selling
commission which will be disclosed in the related Supplement. NationsBanc
Capital Markets, Inc. may also purchase Certificates acting as principal.
