As of [            ,] 1999, which is the "Cut-Off Date," the aggregate size of
the pool of Mortgage Loans (the "Pool Balance") was $          . The Pool
Balance of Mortgage Loans is referred to as the "Cut-Off Date Pool Balance." The
Pool Balances will fluctuate from day to day because the borrowers will make
draws on the Mortgage Loans and principal payments will be made on the Mortgage
Loans.
                                       S-1
<PAGE>   9
 
The per annum interest rate (the "Mortgage Rate") for certain of the Mortgage
Loans is adjusted monthly and the Mortgage Rate for the remainder of the
Mortgage Loans is adjusted every six months. The adjustment date is referred to
as the "Interest Adjustment Date." Subject to its maximum Mortgage Rate, the
Mortgage Rate borne by a Mortgage Loan may be calculated as described under the
"The Mortgage Pool" section of this Prospectus Supplement.
 
ALLOCATIONS OF TRUST ASSETS
 
Distributions of interest and principal to each Holder of a Certificate will be
made on the   th day of each month (or if such   th day is not a business day,
then on the next succeeding business day) (each, a "Distribution Date"),
commencing in           1999, in an amount equal to each such Holder's
respective Percentage Interest multiplied by the amount distributed in respect
of such Class of Certificates.
 
As more fully described in the "Description of the Certificates -- Distributions
on the Certificates" section of this Prospectus Supplement, distributions will
be made:
 
- - to the Class A Certificateholders (up to the amount to which they are entitled
  under the terms of the Agreement),
 
- - then to the Reserve Fund (up to the amount to be required),
 
- - then to the Class B Certificateholders (up to the amount to which they are
  entitled under the terms of the Agreement), and
 
- - any remaining balance to the Class R Certificateholders.
 
The foregoing schedule of distributions is subject to the availability of funds
in the Collection Account (as such term is defined below under "The Mortgage
Pool").
 
[The final payment of principal and interest on the Certificates will be made no
later than                  ,      , or, if that date is not a business day, the
next business day, called the "Legal Final Maturity" or the "Series 1999-
Termination Date"]
 
CREDIT ENHANCEMENT
 
The Certificates may have a Credit Enhancement that provides additional payment
protection to investors in each Class of Certificates that has Credit
Enhancement.
 
[The use of a Reserve Fund, Subordination of certain Subordinate Certificates
and a Credit Insurance Policy may provide Credit Enhancement for the
Certificates].
 
For a discussion on the type of Credit Enhancement available to the
Certificateholders, see "Description of the Certificates -- Reserve Fund",
"-- Subordinated Certificates" and "-- Certificate Insurance Policy" in this
Prospectus Supplement.
 
ADVANCES
 
The Master Servicer is obligated to make advances of cash, which will be part of
the available distribution amount (the "Available Distribution Amount"), in an
amount equal to the delinquent Monthly Payments due on the immediately preceding
Due Date (the "Advances").
 
The Master Servicer is not obligated to make Advances if it determines that such
Advances are not recoverable from future payments or collections on the related
Mortgage Loans. Such Advances, however, will be reimbursed to the Master
Servicer and are not intended to guarantee or insure against losses. See
"Description of the Certificates -- Advances" herein.
 
OPTIONAL TERMINATION
 
The Master Servicer has the option to repurchase from the Trust Fund all
Mortgage Loans remaining outstanding on any Distribution Date when the aggregate
unpaid Principal Balance of such Mortgage Loans is less than 10% of the
aggregate unpaid principal balance of the Mortgage Loans on the Cut-Off Date.
 
If the Master Servicer does not repurchase all the Mortgage Loans, the
Certificate Insurer has the same option.
 
For more information on this option, see "Description of the
Certificates -- Optional Termination" herein.
 
                                       S-2
<PAGE>   10
 
PREPAYMENT AND YIELD CONSIDERATIONS
 
The actual rate of prepayment of principal on the Mortgage Loans cannot be
predicted. The performance of the Class A Certificates may vary materially and
adversely from the investment expectations of investors due to prepayments on
the Mortgage Loans being higher or lower than anticipated by investors. For more
information on the effects that prepayments will have on the yield and
performance of the Certificates, see "Prepayment and Yield Considerations" in
this Prospectus Supplement".
 
DENOMINATIONS
 
Beneficial interest in the Certificates will be offered in minimum denominations
of $1,000 and integral multiples of that amount.
 
REGISTRATION, CLEARANCE AND SETTLEMENT
 
Your Certificates will be registered in the name of Cede & Co., as the nominee
of the Depository Trust Company ("DTC"). You will not receive a definitive
certificate representing your interest, except in limited circumstances
described in the accompanying Prospectus when Certificates in fully registered,
certificated form are issued. See "Description of the
Certificates -- Registration of the Class A Certificates" in this Prospectus
Supplement.
 
You may elect to hold your Certificates through DTC, in the United States, or
Cedel Bank, societe anonyme ("Cedel") or the Euroclear System ("Euroclear"), in
Europe. Transfers within DTC, Cedel or Euroclear, as the case may be, will be
made in accordance with the usual rules and operating procedures of those
systems. Cross-market transfers between persons holding directly or indirectly
through DTC and counterparties holding directly or indirectly through Cedel or
Euroclear will be made in DTC through the relevant depositories of Cedel or
Euroclear. See "Description of the Certificates -- Registration of the Class A
Certificates" in this Prospectus Supplement.
 
We expect that the Certificates will be delivered in book-entry form through the
facilities of DTC, Cedel and Euroclear on or about           , 1999.
 
RECORD DATE
The Record Date will be the last day of the month preceding a Distribution Date.
 
THE MASTER SERVICER
 
The Master Servicer is responsible for servicing, managing and making
collections on the Mortgage Loans. The Master Servicer will also make the
appropriate allocations to the Collection Account.
 
The Master Servicer will be paid a "Servicing Fee Rate" as compensation for its
services to the Trust.
 
For a discussion regarding the Master Servicer's obligations and compensation,
see "Description of the Certificates -- Distributions on the Certificates" in
this Prospectus Supplement.
 
The Master Servicer may be terminated under certain circumstances. See
"Description of the Certificates -- Miscellaneous" in this Prospectus
Supplement.
 
RETRANSFER OF MORTGAGE LOANS
 
The Depositor may be required by certain provisions under the Agreement to
remove Mortgage Loans from the Trust if such Mortgage Loans adversely affect the
he Trust. See "Description of the Certificates -- Assignment of the Mortgage
Loans" in this Prospectus Supplement.
 
TAX STATUS
 
The Trust will make election to be treated as a "real estate mortgage investment
conduit" ("REMIC") under the provisions of the Internal Revenue Code of 1986, as
amended (the "Code"). The election to be treated as a REMIC will have federal
income tax consequences for the Certificateholders. See "Certain Federal Income
Tax Consequences" in the Prospectus
 
ERISA CONSIDERATIONS
 
If you are a fiduciary of an employee benefit plan or other retirement plan or
arrangement that is subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), you must consult with legal advisors to determine if
purchasing or holding of Certificates is a prohibited transaction or otherwise
prohibited under ERISA.
 
                                       S-3
<PAGE>   11
 
Certain classes of Certificates may only be transferred if the Trustee and the
Depositor receive a letter of representations or an opinion of counsel that such
transfer will not violate ERISA or the Code. In addition, the letter of
representation or opinion of counsel must also state that the Trustee, Depositor
or the Master Servicer will not be subject to additional obligations. See "ERISA
Considerations" in the Prospectus.
 
LEGAL INVESTMENT CONSIDERATIONS
 
The Class A Certificates must be rated in one of the two highest rating
categories by at least one nationally recognized statistical rating agency in
order to constitute "mortgage related securities" under the Secondary Mortgage
Market Enhancement Act of 1984. Only "mortgage related securities will be "legal
investments" for certain types of institutional investors to the extent provided
in such Act. See "Legal Investment Considerations" in the Prospectus.
 
USE OF PROCEEDS
 
The net proceeds from the sale of the Class A Certificates will be applied by
the Depositor to the purchase price of the Mortgage Loans and to pay expenses
connected with pooling the Mortgage Loans and issuing the Certificates.
 
CERTIFICATE RATING
 
Any certificate offered by this Prospectus and the accompanying Prospectus
Supplement will be rated in one of the four highest rating categories by at
least one nationally recognized rating organization. Any nationally recognized
rating organization selected by the Seller to rate any Series is a "Rating
Agency."
 
A RATING IS NOT A RECOMMENDATION TO BUY, SELL OR HOLD SECURITIES AND MAY BE
REVISED OR WITHDRAWN AT ANY TIME BY THE ASSIGNING RATING AGENCY. EACH RATING
SHOULD BE EVALUATED INDEPENDENTLY OF ANY OTHER RATING. SEE "CERTIFICATE RATING"
IN THIS PROSPECTUS SUPPLEMENT.

                                  RISK FACTORS
 
     You should consider the following risk factors in deciding whether to
purchase the Certificates.
 
PREPAYMENTS; DUE-ON-SALE PROVISIONS
 
     The rate of distributions of principal and the yield to maturity on your
Certificates will be directly related to the rate of payments of principal on
the Mortgage Loans and the amount and timing of mortgagor defaults resulting in
realized losses. Mortgagors are permitted to prepay the Mortgage Loans, in whole
or in part, at any time without penalty. In addition, a substantial portion of
the Mortgage Loans contain due-on-sale provisions which, to the extent enforced
by the Master Servicer, will result in prepayment of such Mortgage Loan. The
rate of principal payments on the Mortgage Loans will be affected by, among
other things:
 
     - the amortization schedules of the Mortgage Loans;
 
     - the rate of principal prepayments (including partial payments and those
       resulting from refinancing) thereon by mortgagors;
 
     - liquidations of defaulted Mortgage Loans;
 
     - repurchases of Mortgage Loans by the Seller as a result of defective
       documentation or breaches of representations and warranties, or optional
       purchase by the Seller of defaulted Mortgage Loans; and
 
     - the optional purchase by the Seller of all of the Mortgage Loans in
       connection with the termination of the Trust Fund.
 
     See "Prepayment and Yield Considerations" herein, and "The Pooling and
Servicing Agreement -- Assignment of Mortgage Assets" in the Prospectus.
 
     The rate of payments (including prepayments) on mortgage loans is
influenced by a variety of economic, geographic, social and other factors, but
depends greatly on the level of mortgage interest rates:
 
     - If prevailing rates for similar mortgage loans fall below the interest
       rates on the Mortgage Loans, the rate of prepayment would generally be
       expected to increase.
 
     - Conversely, if interest rates on similar mortgage loans rise above the
       interest rates on the Mortgage Loans, the rate of prepayment would
       generally be expected to decrease.
 
     The rate of prepayment on the Mortgage Loans may also be influenced by
programs offered by mortgage originators (including FUNB), on a general or
targeted basis, to encourage refinancing.
 
     If you are purchasing Offered Certificates at a premium, or are purchasing
the Class                Certificates which have no Principal Balance, you
should consider the risk that if principal payments on the Mortgage Loans or in
the case of the Class                Certificates on the Premium Mortgage Loans
(particularly those loans with higher interest rates) occur at a rate faster
than you expected, your yield may be lower than you expected. IF YOU ARE
PURCHASING CLASS                CERTIFICATES, YOU SHOULD CONSIDER THE RISK THAN
A RAPID RATE OF PRINCIPAL PAYMENTS ON THE PREMIUM MORTGAGE LOANS COULD RESULT IN
YOUR FAILURE TO RECOVER YOUR INITIAL INVESTMENT.
 
LIMITED LIQUIDITY
 
     There is currently no market for the Offered Certificates. While the
Underwriters currently intend to make a market in the Offered Certificates, they
are under no obligation to do so. There can be no assurance that a secondary
market will develop or, if a secondary market does develop, that it will provide
you with liquidity of investment or that it will continue for the lives of the
Offered Certificates. The Offered Certificates will not be listed on any
securities exchange.
 
     Issuance of the Offered Certificates in book-entry form may reduce the
liquidity of such Certificates in the secondary trading market since investors
may be unwilling to purchase Offered Certificates for which they cannot obtain
physical certificates. See "Description of the Certificates -- Book-Entry
Registration" herein.
                                       S-5
<PAGE>   13
 
RISKS ASSOCIATED WITH MORTGAGE LOANS
 
     Adverse economic conditions (which may or may not affect real property
values) may affect the timely payment by borrowers of payments of principal and
interest when due on the Mortgage Loans and, accordingly, the actual rates of
delinquencies, foreclosures and losses with respect to the Mortgage Loans.
Further, application of federal and state bankruptcy and debtor relief laws
would affect the interests of the Certificateholders in the Mortgage Loans if
such laws result in certain Mortgage Loans being uncollectible. See "Certain
Legal Aspects of the Mortgage Loans -- Anti-Deficiency Legislation; Bankruptcy
and Consumer Protection Legislation" herein.
 
     Even assuming that the Mortgaged Properties provide adequate security for
the Mortgage Loans, delays could be encountered in connection with the
liquidation of defaulted Mortgage Loans, with corresponding delays in the
receipt of related proceeds by the Certificateholders.
 
     Further, the Master Servicer will be entitled to deduct from Liquidation
Proceeds all expenses reasonably incurred in attempting to recover amounts due
on Liquidated Mortgage Loans and not yet repaid, including legal fees and costs
of legal action, real estate taxes, and maintenance and preservation expenses,
thereby reducing collections available to the Certificateholders.
 
     In the event that any Mortgaged Properties fail to provide adequate
security for the related Mortgage Loans and the protection provided by the
subordination feature is insufficient, Certificateholders could experience a
loss on their investment. See "Certain Legal Aspects of the Mortgage
Loans -- Foreclosure" and "-- Rights of Redemption" herein.
 
     Under federal and state environmental legislation and applicable case law,
it is unclear whether liability for costs of eliminating environmental hazards
in respect of real property may be imposed on a secured lender (such as the
Trust Fund) acquiring title to such real property. Such costs could be
substantial. See "Certain Legal Aspects of the Mortgage Loans -- Environmental
Legislation" herein.
 
GEOGRAPHIC CONCENTRATION/LOCAL REAL ESTATE MARKETS
 
     Approximately      % of all Mortgage Loans (by Cut-Off Date Principal
Balances) are secured by Mortgaged Properties located in the State of
               . In addition, approximately      %,      %, and      % of the
Mortgage Loans are located in                ,                , and
               , respectively. See "Certain Legal Aspects of the Mortgage Loans"
and "The Mortgage Loan Pool" herein.
 
     An overall decline in the residential real estate markets in the states in
which the Mortgaged Properties are located could adversely affect the values of
the Mortgaged Properties such that the outstanding loan balances equal or exceed
the value of the Mortgaged Properties. Such declines could reduce the interest
of the holder of a mortgage on the Mortgaged Property. Residential real estate
markets in many states have softened in recent years. There is no reliable
information available to the Seller with respect to the rate at which real
estate values have declined in such states. The Seller can neither quantify the
impact of such declines in property values nor predict how long such declines
may continue or when such declines will end. During a period of such declines,
the rates of delinquencies, foreclosures and losses on the Mortgage Loans would
be expected to be higher than those experienced in the mortgage lending industry
in general.
 
     A rise in interest rates over a period of time and the general condition of
the Mortgaged Property as well as other factors may have the effect of reducing
the value of the Mortgaged Property from the appraised value at the time the
Mortgage Loan was originated. If there is a reduction in value of the Mortgaged
Property, the ratio of the amount of the Mortgage Loan to the value of the
Mortgaged Property may increase over what it was at the time the Mortgage Loan
was originated. Such an increase may reduce the likelihood of liquidation or
other proceeds being sufficient to satisfy the Mortgage Loan after satisfaction
of any senior liens.
 
RISKS OF HOLDING SUBORDINATE CERTIFICATES
 
     The rights of the Holders of each Class of Subordinate Certificates to
receive distributions will be subordinated to such rights of the Holders of the
Class A Certificates, and the Class M Certificates, and the
 
                                       S-6
<PAGE>   14
 
lower-numbered Classes of Class B Certificates, if any, with respect to Class B
Certificates. In addition, realized losses, other than excess losses, will be
allocated to the Subordinate Certificates in the reverse order in which they are
entitled to distributions of principal before being allocated to the Class A
Certificates. Accordingly, if you are purchasing Subordinate Certificates, you
will be more likely to experience losses as a result of the occurrence of losses
or interest shortfalls on the Mortgage Loans.
 
     Under certain circumstances principal otherwise payable to the Subordinate
Certificates will be paid to the Class A Certificates (other than the Class
               Certificates) as described under "Description of the
Certificates -- Cross-Collateralization" herein. In addition, the Class
               Deferred Amount is payable from amounts otherwise distributable
as principal on the Subordinate Certificates.
 
LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO DEPOSITOR, SELLER, MASTER
SERVICER, TRUST ADMINISTRATOR, OR TRUSTEE
 
     The Certificates do not represent an interest in or obligation of the
Depositor, the Seller, the Master Servicer, the Trustee or any of their
affiliates, except for the limited obligations of the Depositor and the Seller
with respect to certain breaches of their representations and warranties and of
the Master Servicer with respect to its servicing obligations.
 
     Neither the Certificates nor the Mortgage Loans will be guaranteed by or
insured by any governmental agency or instrumentality, the Depositor, the
Seller, 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 Depositor, the Seller, the Master Servicer, the
Trustee, or any of their affiliates.
 
BOOK-ENTRY SYSTEM
 
     Since transactions in the Class A Certificates (other than the Residual
Certificates) and the Senior Subordinate Certificates (collectively, the
"Book-Entry Certificates") generally can be effected only through The Depository
Trust Company ("DTC"), participating organizations, indirect participants and
certain banks, your ability as a Certificateholder to pledge a Book-Entry
Certificate to persons or entities that do not participate in the DTC system, or
otherwise to take actions with respect to such Certificates, may be limited due
to a lack of a physical certificate representing the Book-Entry Certificates.
 
     In addition, as a Certificateholder, you may experience some delay in the
receipt of distribution of interest and principal on the Book-Entry
Certificates, since such distributions will be forwarded by the Trustee (or its
duly appointed paying agent, if any) to DTC, and DTC will credit such
distributions to the accounts of DTC Participants (as defined herein) which will
thereafter credit them to the accounts of Certificateholders either directly or
indirectly through indirect participants.
 
     Also, issuance of the 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 "Description of the
Certificates -- Book-Entry Registration" herein.
 
CERTIFICATE RATINGS
 
     The rating of the Offered Certificates will depend primarily on an
assessment by the Rating Agencies of the underlying Mortgage Loans and the
amount of subordination.
 
     The rating by the Rating Agencies of the Offered Certificates is not a
recommendation to purchase, hold or sell the Offered Certificates, in as much as
such rating does not comment as to the market price or suitability for a
particular investor. There is no assurance that the ratings will remain for any
given period of time or that the ratings will not be reduced, suspended or
withdrawn by the Rating Agencies.
 
                                       S-7
<PAGE>   15
 
RISK OF YEAR 2000
 
     FUNB and the Trustee utilize a significant number of computer software
programs and operating systems and are highly dependent on computer systems
operated by third parties which include, but are not limited to, their
suppliers, customers, brokers and agents and the telephone, electric and utility
companies. To the extent that any computer system relied upon by FUNB and the
Trustee or any third party, has software applications and contains source codes
that are unable to appropriately interpret the upcoming calendar year 2000, some
level of modification or replacement of such applications or hardware may be
necessary.
 
     The year 2000 issue is the result of prior computer programs being written
using two digits, rather than four digits, to define the applicable year. Any of
FUNB's or the Trustee's computer programs that have time-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. Any such
occurrence could result in a major computer system failure or miscalculations.
Several federal regulatory agencies, including the Securities and Exchange
Commission, require the entities that they regulate to take steps to address
problems which may arise in relation to the year 2000.
 
     FUNB and the Trustee currently are assessing the impact of modifications or
replacements required to adjust for the year 2000. FUNB and the Trustee are
utilizing both internal and external resources to identify, correct or
reprogram, and test their systems for year 2000 compliance. It is anticipated
that all reprogramming efforts and necessary testing will be completed prior to
the year 2000. FUNB and the Trustee have initiated formal communications with
those third parties on whom they will rely to determine the extent to which FUNB
and the Trustee are vulnerable to the failure of these third parties to
remediate their own year 2000 issue. The total year 2000 project cost and
estimates for FUNB and the Trustee include the estimated costs and time
associated with the impact of a third party's year 2000 issue, and are based on
presently available information. However, there can be no assurance that the
systems of third parties on which the systems of FUNB and the Trustee rely will
be converted in a timely fashion, or that a failure to convert by a third party,
or a conversion that is incompatible with the systems of FUNB and the Trustee
would not have an adverse effect on the business, financial condition or results
of operations of FUNB and the Trustee.
 
     The costs allocated to the year 2000 project are significant. The costs of
the project and the dates on which FUNB and the Trustee plan to complete their
year 2000 modifications are based on their best estimates, which were derived
utilizing numerous assumptions of future events including the continued
availability of certain resources, third party modification plans and other
factors. However, there can be no assurance that these estimates will be
achieved and actual results could differ materially from such estimates.
Specific factors that might cause such material differences include, but are not
limited to: (i) the availability and cost of personnel trained in this area,
(ii) the ability to locate and correct all relevant computer codes and (iii)
similar uncertainties.
 
     No assurance can be given that any or all of the systems discussed above,
including the systems of FUNB and the Trustee, are or will be year 2000
compliant or that the costs required to address year 2000 issues will not
adversely affect the business, financial condition or results of operations of
the respective party or the performance of their obligations under the Pooling
and Servicing Agreement. As a result of this potential affect on performance
under the Pooling and Servicing Agreement, the timely receipt of payment by the
Certificateholders may also be adversely affected.
 
     DTC has informed its participants and other members of the financial
community (the "Industry") that it believes that it has developed and is
implementing a program so that its computer hardware and software systems, as
the same relate to the timely payment of distributions (including principal and
income payments) to securityholders, book-entry deliveries, and settlement of
trades within DTC, will continue to function appropriately. This program
includes a technical assessment and remediation plan, each of which, according
to DTC, is complete. Additionally, DTC's plan includes a testing phase which is
expected to be completed within appropriate time frames.
 
     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors on whom DTC relies for information or the provision
of services, including telecommunication and electrical utility service
providers, among others.
 
                                       S-8
<PAGE>   16
 
DTC has informed the Industry that it is contacting (and will continue to
contact) third party vendors from whom DTC acquires services to: (1) impress
upon them the importance of such services being year 2000 compliant; and (2)
determine the extent of their efforts for year 2000 remediation (and, as
appropriate, testing) of their services. In addition, DTC is in the process of
developing such contingency plans as it deems appropriate.
 
     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for information purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.
 
OTHER LEGAL CONSIDERATIONS
 
     Certain states have imposed statutory prohibitions which limit the remedies
of either a beneficiary under a deed of trust or security deed or a mortgagee
under a mortgage. In some states, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure or sale under a deed of trust, security deed or mortgage. A
deficiency judgment would be a personal judgment against the former borrower
equal in most cases to the difference between the net amount received upon the
public sale of the real property and the amount due to the lender.
 
     Other statutes require the beneficiary or mortgagee to exhaust the security
afforded under a deed of trust, security deed or mortgage by foreclosure in an
attempt to satisfy the full debt before bringing a personal action against the
borrower.
 
     Finally, other statutory provisions limit any deficiency judgment against
the former borrower following a judicial sale to the excess of the outstanding
debt over the fair market value of the property at the time of the public sale.
The purpose of these statutes is generally to prevent a beneficiary or a
mortgagee from obtaining a large deficiency judgment against the former borrower
as a result of low or no bids at the judicial sale.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of the Seller. In addition,
other state laws, public policy and general principles of equity relating to the
protection of consumers, unfair and deceptive practices and debt collection
practices may apply to the origination, servicing and collection of the Mortgage
Loans.
 
     The Seller will be required to repurchase any Mortgage Loans which, at the
time of origination did not comply with applicable federal and state laws and
regulations. Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and
principles may limit the ability of the Trust Fund to collect all or part of the
principal of or interest on the Mortgage Loans, may entitle the borrower to a
refund of amounts previously paid and, in addition, could subject the Trust Fund
to damages and administrative enforcement. See "Certain Legal Aspects of
Mortgage Loans" herein.
 
     The Mortgage Loans are also subject to federal laws, including:
 
     - the federal Truth in Lending Act and Regulation Z promulgated thereunder,
       which require certain disclosures to the borrowers regarding the terms of
       the Mortgage Loans;
 
     - the Equal Credit Opportunity Act and Regulation B promulgated thereunder,
       which prohibit discrimination on the basis of age, race, color, sex,
       religion, marital status, national origin, receipt of public assistance
       or the exercise of any right under the Consumer Credit Protection Act, in
       the extension of credit;
 
     - the Fair Credit Reporting Act, which regulates the use and reporting of
       information related to the borrower's credit experience;
 
     - the Americans with Disabilities Act, which, among other things, prohibits
       discrimination on the basis of disability in the full and equal enjoyment
       of the goods, services, facilities, privileges, advantages or
       accommodations of any place of public accommodation; and
 
     - the Real Estate Settlement Procedures Act and the Fair Credit Billing
       Act.
 
                                       S-9
<PAGE>   17
 
     The federal Soldiers' and Sailors' Civil Relief Act of 1940 may affect the
ability of the Master Servicer to collect full amounts of interest on certain
Mortgage Loans and could interfere with the ability of the Master Servicer to
foreclose on certain properties. See "Certain Legal Aspects of the Mortgage
Loans -- Soldiers' and Sailors' Civil Relief Act of 1940" herein.
 
RISK OF EARLY DEFAULTS
 
     The majority of the Mortgage Loans were originated within      months prior
to the Cut-Off Date. The weighted average stated remaining term to maturity of
the Mortgage Loans as of the Cut-Off Date is approximately      months. Although
little data is available, defaults on mortgage loans, including mortgage loans
similar to the Mortgage Loans, are generally expected to occur with greater
frequency in the early years of the terms of mortgage loans.
 
                               THE MORTGAGE POOL
 
     The mortgage pool with respect to the Certificates (the "Mortgage Pool")
will consist of approximately      conventional mortgage loans evidenced by high
balance, adjustable interest rate promissory notes (each, a "Mortgage Note")
having an aggregate principal balance as of the Cut-Off Date of approximately
$       . The Mortgage Notes are secured by mortgages or deeds of trust or other
similar security instruments creating first liens on one- to four-family
residential properties (the "Mortgaged Properties"). The Mortgage Loans were
originated by the Seller, or acquired by the Seller in the ordinary course of
its real estate lending activities. With respect to approximately      % of the
Mortgage Loans (by Cut-Off Date Principal Balance), the borrowers were initially
solicited by, and the documentation for the Mortgage Loans was processed by,
mortgage brokers, mortgage bankers, credit unions and other financial
institutions that are not affiliated with the Seller. Personnel of the Seller or
its agents reviewed the documentation for each such Mortgage Loan and underwrote
such loans in accordance with the Seller's underwriting standards.
 
     The Mortgaged Properties will consist of detached individual dwelling
units, individual condominiums, townhouses, duplexes, individual units in
planned unit developments and other attached dwelling units. Based upon
representations obtained from the mortgagors at the time of origination of the
Mortgage Loans, approximately      % (by Cut-Off Date Principal Balance) of the
related Mortgaged Properties are owner-occupied. At the date of issuance of the
Certificates, none of the Mortgage Loans will be delinquent more than 30 days.
The Trust Fund will include, in addition to the Mortgage Pool, (i) the amounts
held from time to time in one or more accounts (collectively, the "Collection
Account") maintained in the name of the Trustee, pursuant to the Pooling and
Servicing Agreement dated as of             , 1999 (the "Agreement"), by and
among the Depositor, the Seller, as master servicer (the "Master Servicer"), and
               , as trustee (the "Trustee"), (ii) the amounts held from time to
time in the Distribution Account (the "Distribution Account") maintained in the
name of the Trustee pursuant to the Agreement, (iii) any property which
initially secured a Mortgage Loan and which is acquired by foreclosure or deed
in lieu of foreclosure, (iv) all insurance policies and the proceeds thereof
described below, (v) any right to require the Seller to repurchase or substitute
for the Mortgage Loans on account of certain breaches of representation and
warranty as set forth in the Agreement, (vi) the Reserve Fund and (vii) the
Certificate Insurance Policy and the proceeds thereof.
 
     The Depositor will purchase the Mortgage Loans from the Seller and will
cause such Mortgage Loans to be assigned to the Trustee. The Master Servicer
will service the Mortgage Loans, either by itself or through other mortgage
servicing institutions (the "Subservicers"), pursuant to the Agreement. With
respect to any Mortgage Loans serviced by the Master Servicer through a
Subservicer, the Master Servicer will remain liable for its servicing
obligations under the Agreement as if the Master Servicer alone were servicing
such Mortgage Loans.
 
     The Seller will make certain representations and warranties for the benefit
of the Depositor, the Certificate Insurer and the Trustee with respect to the
Mortgage Loans as described in the Prospectus under "Mortgage Loan
Program -- Representations by Sellers; Repurchases" and will have a
responsibility to repurchase a Mortgage Loan as to which there is a breach of
such representations and warranties that materially and adversely affects the
value of that Mortgage Loan and is not timely cured. The only remedy
                                      S-10
<PAGE>   18
 
available to Certificateholders for a breach of these representations and
warranties will be the repurchase obligation of the Seller provided in the
Agreement as described in the sections of the Prospectus referred to above. The
Trustee will enforce the Seller's repurchase obligation, and the Depositor will
not be obligated to repurchase any Mortgage Loan for such a breach of any
representation or warranty. In lieu of such repurchase obligation, the Seller
may, within two years after the date of initial delivery of the Certificates,
substitute for the affected Mortgage Loan a substitute Mortgage Loan, as
described under "Mortgage Loan Program  -- Representations by Sellers;
Repurchases" in the Prospectus and as provided by the Agreement.
 
     Certain data with respect to the Mortgage Loans is set forth below.
References herein to percentages of Mortgage Loans refer in each case to the
percentage of the aggregate principal balance of the Mortgage Loans as of the
Cut-Off Date, based on the outstanding balances of the Mortgage Loans as of the
Cut-Off Date, giving effect to scheduled monthly payments (the "Monthly
Payments")due on or prior to the Cut-Off Date.
 
     The per annum interest rate (the "Mortgage Rate") for certain of the
Mortgage Loans is adjusted monthly and the Mortgage Rate for the remainder of
the Mortgage Loans is adjusted every six months. The adjustment date is referred
to as the "Interest Adjustment Date." Subject to its maximum Mortgage Rate, the
Mortgage Rate borne by a Mortgage Loan may be calculated as follows:
 
     Prime Index.  The Mortgage Rate borne by      % of the Mortgage Loans (by
Cut-Off Date Principal Balance) is adjusted every month and the Mortgage Rate
borne by      % of the Mortgage Loans (by Cut-Off Date Principal Balance) is
adjusted every six months, to equal either (i) the highest Prime Rate listed
under "Money Rates" in The Wall Street Journal most recently available as of 45
days prior to such Interest Adjustment Date (the "Prime Index") minus a margin
(the "Margin") generally ranging from      % to zero or (ii) such Prime Index
plus a Margin generally ranging from zero to      %
 
     Six-Month LIBOR Index.  The Mortgage Rate borne by      % of the Mortgage
Loans (by Cut-Off Date Principal Balance) is adjusted every six months to equal
the London interbank offered rate for six-month U.S. dollar deposits (the
"Six-Month LIBOR Index") as listed under "Money Rates" in The Wall Street
Journal most recently available as of 45 days prior to the related Interest
Adjustment Date plus a Margin generally ranging from      % to      %.
 
     One-Month LIBOR Index.  The Mortgage Rate borne by      % of the Mortgage
Loans (by Cut-Off Date Principal Balance) is adjusted every month to equal the
London interbank offered rate for one-month U.S. dollar deposits (the "One-Month
LIBOR Index") as listed under "Money Rates" in The Wall Street Journal most
recently available as of 45 days prior to the related Interest Adjustment Date
plus a Margin generally ranging from      % to      %.
 
     Treasury Index.  The Mortgage Rate borne by      % of the Mortgage Loans
(by Cut-Off Date Principal Balance) is adjusted every six months, and the
Mortgage Rate borne by      % of the Mortgage Loans (by Cut-Off Date Principal
Balance) is adjusted monthly, to equal the weekly average yield on the United
States Treasury Securities adjusted to a constant maturity of one year, as made
available by the Federal Reserve board in Statistical Release H.15 (the
"Treasury Index") most recently available as of 45 days prior to the related
Interest Adjustment Date plus a Margin generally ranging from      % to      %.
 
     Approximately      % of the Mortgage Loans are One-Month LIBOR Index based
Mortgage Loans, approximately      % are Six-Month LIBOR Index based Mortgage
Loans, approximately      % are Prime Index based Mortgage Loans that adjust
monthly,      % are Prime Index based Mortgage Loans that adjust every six
months, approximately      % are Treasury Index based Mortgage Loans that adjust
monthly and approximately      % are Treasury Index based Mortgage Loans that
adjust every six months. Approximately      % of the Mortgage Loans are
Convertible Mortgage Loans.
 
     The Mortgage Loans were originated between                  , 199 , and
                 , 199 . No more than      % of the Mortgaged Properties
securing the Mortgage Loans are located in any one zip code area. At
origination, all of the Mortgage Loans had terms to stated maturity of
               years. The latest month and year in which any Mortgage Loan
matures is                  202 . The Mortgage Loans had remaining terms to
stated maturity, calculated as of the Cut-Off Date, of between approximately
               and        months and a weighted average remaining term to stated
maturity as of the Cut-Off
                                      S-11
<PAGE>   19
 
Date of approximately        months. The interest rates (the "Mortgage Rates")
borne by the Mortgage Loans as of the Cut-Off Date ranged from      % per annum
to      % per annum and the weighted average Mortgage Rate as of the Cut-Off
Date was approximately      % per annum.
 
     Each Mortgage Loan had an original principal balance of not less than
$          nor more than $          . The average outstanding principal balance
of the Mortgage Loans as of the Cut-Off Date was approximately $          .
 
     Set forth below is a description of certain additional characteristics of
the Mortgage Loans.

                       THE SELLER AND THE MASTER SERVICER
 
GENERAL
 
     First Union National Bank is the Seller and Master Servicer under the
Pooling and Servicing Agreement. First Union National Bank is a national banking
association and a banking subsidiary of First Union Corporation, a North
Carolina corporation and a multi-bank holding company registered under the Bank
Holding Company Act. First Union Corporation is the                largest bank
holding company in the United States based on total assets as of December 31,
               .
 
     The Offered Certificates will not represent an interest in or obligation
of, nor are the Mortgage Loans guaranteed by, the Seller, the Master Servicer,
or any of their affiliates.
 
     The Master Servicer will use subservicers (the "Subservicers") in the
performance of the administrative and servicing obligations of the Master
Servicer under the Pooling and Servicing Agreement, but no such subservicing
arrangements will discharge the Master Servicer from its obligations under the
Pooling and Servicing Agreement.
 
     The Trustee may remove the Master Servicer, and the Master Servicer may
resign, only in accordance with the terms of the Pooling and Servicing
Agreement. No removal or resignation shall become effective until the Trustee or
a successor servicer shall have assumed the Master Servicer's responsibilities
and obligations in accordance therewith.
 
     Any collections received by the Master Servicer after removal or
resignation shall be endorsed by it to the Trustee and remitted directly to the
Trustee.
 
CREDIT AND UNDERWRITING GUIDELINES
 
     The following is a description of the underwriting guidelines customarily
employed by the Seller with respect to mortgage loans which it purchases
(including by acquisitions or mergers) or originates. The Seller believes that
some of the Mortgage Loans were underwritten with exceptions to these
guidelines. Those that were made with exceptions to these underwriting
guidelines were approved when other compensating factors existed. The Seller
believes its standards are consistent with those utilized by mortgage lenders
generally. The underwriting process is intended to assess both the prospective
borrower's ability to repay and the adequacy of the real property security as
collateral for the loan granted. The Seller's general underwriting guidelines
are specified in the "FUNB Mortgage Loan Conduit -- Seller Guide." The Seller
Guide is available upon request
                                      S-18
<PAGE>   26
 
by contacting the Seller at (704) 374-6607. Approximately      % of the Mortgage
Loans (by Cut-Off Date Principal Balances) are originated under the Seller's
"ESP guidelines" as specified in Sections 8.5 through 8.15 of the Seller Guide.
The ESP program provides for reduced documentation, expanded loan parameters or
international borrowers in cases where such factors are off-set by excellent
credit characteristics of the borrower. Loans may be made outside of those
guidelines with the prior approval of a senior official of the Seller. Of the
Mortgage Loans, approximately      % were underwritten to alternative
documentation and approximately      % were underwritten to limited
documentation.
 
     The Seller generally originates or purchases fixed rate loans, which fully
amortize over a period not to exceed 360 months. The original loan amounts
generally range from a minimum of $227,151 to a maximum of $1,000,000.
 
     The homes used for collateral to secure the loans may be either primary
residential (which includes second and vacation homes) or investor owned one-to
four-family homes, condominiums, planned unit developments or modular homes or
townhouses.
 
     The Loan-to-Value Ratio generally may not exceed 95% for a primary
residence and 90% for a second home. Each property proposed as security for a
loan must be appraised.
 
     Each mortgage applicant generally provides, and the Seller generally
verifies, personal financial information. The applicant's total monthly
obligations (which includes principal and interest on each mortgage, tax
assessments, other loans, charge accounts and all other scheduled indebtedness)
generally cannot exceed 38% of the applicant's gross monthly income. Applicants
who are salaried employees must provide current employment information in
addition to two recent years of employment history and the Seller verifies this
information. Verifications are based on written confirmation from employers or a
combination of a recent pay stub, the most recent W-2 tax form and telephone
confirmation from the employer. Self-employed applicants must be self-employed
in the same field for a minimum of two years. The self-employed applicant must
provide signed copies of complete federal income tax returns (including
schedules) filed for the most recent two years.
 
     A credit report by an independent credit reporting agency is generally
required reflecting the applicant's complete credit history. The credit report
should reflect all delinquencies of 30 days or more, repossessions, judgments,
foreclosures, garnishments, bankruptcies, divorce actions and similar adverse
credit practices that can be discovered by a search of public records. If the
report is obtained more than 120 or 180 days (depending on type of property)
prior to the loan closing, the lender must determine that the reported
information has not changed. All taxes and assessments not included in the
payment must be verified as current.
 
     The Seller is responsible for using sound judgment in underwriting the
loans consistent with prudent industry practices. Generally, the applicant
should have an acceptable credit history given the amount of equity available,
the strength of the applicant's employment history and the level of the
applicant's income to debt obligations. The rescission period must have expired
prior to funding a loan. The rescission period may not be waived by the
applicant except as permitted by law. An attorney's title opinion or an ALTA
title insurance policy is required for all loans.
 
     The applicant is required to secure property insurance in an amount
sufficient to cover the new loan. The Seller must ensure that its name and
address is properly added to the mortgagee clause of the insurance policy.
 
STREAMLINED FUNDING PROGRAM
 
     Approximately      % of the Mortgage Loans (the "Streamlined Funding
Loans") have been originated by First Union Mortgage Corporation and third party
correspondents under the Seller's Streamlined Funding Program. These Streamlined
Funding Loans have been underwritten in compliance with the Seller's guidelines
and comply with appraisal requirements, minimum FICO credit scores,
loan-to-value ratios, credit requirements, and all other general underwriting
guidelines of the Seller.
 
                                      S-19
<PAGE>   27
 
     The Seller reviews a 10% to 30% sample of the credit files for the
Streamlined Funding Loans depending on the correspondent and based on various
factors. No additional credit review will be performed. Correspondents that
submit loans through the Streamlined Funding Program represent and warrant to
the Seller that all of the loans meet the Seller's underwriting guidelines. The
Seller, in turn, will make similar representations and warranties to the Trust
Fund based on its review. The loans are purchased pursuant to the delivery of
the legal files for each loan and the credit files for the sample loans. The
legal files consist of: (i) the Note endorsed to the Seller; (ii) a power of
attorney, if applicable; (iii) a loan modification, if applicable; (iv) the
security instrument and riders; (v) any assignments, intervening and to the
Seller; (vi) the title binder; and (vii) the Private Mortgage Insurance
Certification, if applicable.
 
DELINQUENCY, LOAN LOSS AND FORECLOSURE INFORMATION
 
     The following table sets forth the Master Servicer's delinquency
experience, on a servicing portfolio of mortgage loans similar to the Mortgage
Loans, at the dates indicated below. The Master Servicer's portfolio of mortgage
loans may differ significantly from the Mortgage Loans included in the Trust
Fund in terms of interest rates, principal balances, geographic distribution,
Loan-to-Value Ratios and other relevant characteristics. There can be no
assurance the delinquency and loss experienced on the Mortgage Loans (most of
which have been acquired by the Seller during the past twelve months) will be
consistent with the historical information provided below. Such losses and
delinquencies on the Mortgage Loans may be higher than the historical
information presented below.
 
     The following table sets forth information relating to the delinquency
experience of mortgage loans serviced by the Master Servicer that are similar to
and including the Mortgage Loans for the four quarters ended June 30,      ,
September 30,      and December 31      and March 31,      .

(1) The period of delinquency is based on the number of days the payment is
    contractually past due.
 
     The above delinquency experience percentages are calculated on the basis of
the total mortgage loan portfolio of similar loans serviced by the Master
Servicer at the date indicated, all of which loans were acquired or originated
by the Master Servicer. However, because the total amount of loans serviced by
the Master Servicer has increased over these periods as a result of new
originations, the total amount of loans serviced as of the end of any indicated
period will include many loans that will not have been outstanding long enough
to give rise to some or all of the indicated periods of delinquency. Because the
Trust Fund consists of a fixed group of Mortgage Loans, the actual delinquency
percentages with respect to the Mortgage Loans may differ from the delinquency
percentages indicated above.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
     The rate of principal payments on the Class A Certificates, the aggregate
amount of each interest payment on such Certificates and the yields to maturity
of such Certificates are related to and affected by the rate and timing of
payments of principal on the underlying Mortgage Loans. The principal payments
on the
 
                                      S-20
<PAGE>   28
 
Mortgage Loans may be in the form of scheduled principal payments or prepayments
or liquidation proceeds due to default, casualty, condemnation and the like. Any
such payments will result in distributions to the Certificateholders of amounts
attributable to principal which would otherwise be distributed over the
remaining term of the Mortgage Loans. In addition, because the Class A
Certificates will be entitled to receive all or a disproportionate percentage of
unscheduled principal payments on the Mortgage Loans (including liquidations due
to default) on each Distribution Date until the Class A Principal Balance is
reduced to zero, rather than the portion thereof proportionate to their interest
in the Mortgage Loans, the rate of principal payments on the Mortgage Loans
will, unless offset by cash flow insufficiencies due to delinquencies and
liquidation losses, have a greater effect on the rate of principal payments and
the amount of interest payments on, and the yields to maturity of, the Class A
Certificates than if the Class A Certificates were entitled only to their
proportionate interest in the Formula Principal Distribution Amounts for the
Mortgage Loans. See "Description of the Certificates -- Distributions on the
Certificates" herein. In general, the prepayment rate may be influenced by a
number of factors, including general economic conditions, homeowner mobility and
the level of mortgage market interest rates. Mortgagors are permitted to prepay
the Mortgage Loans, in whole or in part, at any time without penalty. The rate
of payment of principal may also be affected by any repurchase of the Mortgage
Loans by the Master Servicer or the Certificate Insurer as described herein. See
"The Mortgage Pool" and "Description of the Certificates -- Optional
Termination" herein. In such event, the repurchase price will be passed through
to the applicable Certificateholders as a prepayment of principal in the month
following the month of such repurchase.
 
     All of the Mortgage Loans are adjustable rate loans for which only interest
is due during the first ten years of their terms. Approximately      % of the
Mortgage Loans (by Cut-Off Date Principal Balance) are Convertible Mortgage
Loans, in respect of which the Mortgagor, during the related conversion period,
may convert the adjustable rate to a fixed rate and may convert to a different
Index (and may thereafter convert to a fixed rate). The Depositor is not aware
of any publicly available statistics that set forth principal prepayment or
conversion experience or prepayment or conversion forecasts of adjustable rate
mortgage loans over an extended period of time, and the experience of the Seller
is insufficient to draw any conclusions with respect to the expected prepayment
or conversion rates on the Mortgage Loans. The rate of principal prepayments and
conversions with respect to adjustable rate mortgage loans has fluctuated in
recent years. As is the case with conventional fixed rate mortgage loans,
adjustable rate mortgage loans may be subject to a greater rate of principal
prepayments and conversions in a declining interest rate environment. For
example, if prevailing interest rates fall significantly, adjustable rate
mortgage loans could be subject to higher prepayment rates than if prevailing
interest rates remain constant because the availability of fixed rate or other
adjustable rate mortgage loans at competitive interest rates may encourage
mortgagors to refinance their adjustable rate loans, or convert them to a fixed
rate or other adjustable rate, to "lock in" a lower adjustable or fixed interest
rate. The fixed rate conversion option may also be exercised in a rising
interest rate environment as Mortgagors avoid the risk of higher rates. No
prediction can be made as to the rate of prepayments or conversions on the
Mortgage Loans in stable or changing interest rate environments. If a
substantial number of Mortgagors exercise their conversion option with respect
to the Convertible Mortgage Loans to convert to a fixed rate, and the Master
Servicer purchases such Converting Mortgage Loans, the Mortgage Loans will, in
effect, experience substantial prepayments of principal. If the Master Servicer
fails to purchase Converting Mortgage Loans that are converting to a fixed rate,
then the Mortgage Loans will include fixed rate Mortgage Loans, which will have
the effect of limiting the extent to which the Net Mortgage Rate can increase
(or decrease) in accordance with changes in the Indices and accordingly may
limit the Class A Pass-Through Rate on the Class A Certificates to the related
Weighted Average Net Mortgage Rate rather than the applicable Class A
Pass-Through Rate calculated on the basis of the LIBOR formula. The Master
Servicer will not purchase of Mortgage Loans upon their conversion to a
different Index. Consequently, the Mortgage Loans will include any such Mortgage
Loans with the different Index, which may have an adverse effect on the level of
the Class A Pass-Through Rate. See "Yield and Prepayment Considerations" in the
Prospectus.
 
     To the extent that amounts paid to the Holders of the Class A Certificates
on any Distribution Date are less than the amount due to the Holders of the
Class A Certificates on such date, the weighted average life of the Class A
Certificates will be longer than if shortfalls had not occurred.
 
                                      S-21
<PAGE>   29
 
     In the case of any Class A Certificates purchased at a discount to their
original principal amounts, a slower than anticipated rate of principal payments
is likely to result in a lower than anticipated yield. In the case of Class A
Certificates purchased at a premium to their original principal amounts, a
faster than anticipated rate of principal payments is likely to result in a
lower than anticipated yield.
 
     In the event of the acceleration of Mortgage Loans as a result of
enforcement of "due-on-sale" provisions in connection with transfers of the
related Mortgaged Properties or the occurrence of certain other events resulting
in acceleration as described under "Description of the Certificates -- Servicing
and Insurance," the level of prepayments on the Mortgage Loans will be affected,
thereby shortening the weighted average life of the Class A Certificates. See
"Yield and Prepayment Considerations" in the Prospectus.
 
     If a Mortgage Loan is prepaid in full, interest thereon will cease to
accrue on the date of the prepayment. Consequently, the timing of prepayments in
full on Mortgage Loans will affect the amount of the Available Distribution
Amount available to make distributions of interest on the Certificates and will
therefore affect the ability of the Trust Fund to make a full distribution of
interest on the Class A Certificates and the Formula Principal Distribution
Amount. The Master Servicer's Servicing Fee in respect of the month of
prepayment will be applied to make up for any reduced amount of interest
collections on account of the timing of the receipt of principal prepayments,
but no assurance can be given that the amount of the Servicing Fee will be
sufficient for such purpose. Net Interest Shortfalls will be borne by the
Certificateholders as described under "Description of the
Certificates -- Distributions on the Certificates" and will result in a lower
than anticipated yield.
 
     No prediction can be made as to future levels of LIBOR, the One-Month LIBOR
Index, the Six-Month LIBOR Index, the Prime Index or the Treasury Index or as to
the timing of any changes therein, each of which will directly affect the yields
of the Class A Certificates. In addition, the Holders of the Class A
Certificates will absorb the yield risk associated with a possible narrowing of
the spread between the Class A Pass-Through Rate (which rate, except as
otherwise provided, is based on LIBOR) and the Weighted Average Net Mortgage
Rate. The Mortgage Rates reset at different times and are subject to lifetime
interest rate caps. The conversions of Convertible Mortgage Loans to a fixed
rate may, if the Master Servicer fails to purchase such Converting Mortgage
Loans, have the effect of narrowing the spread between the Class A Pass-Through
Rate calculated on the basis of LIBOR and the Weighted Average Net Mortgage
Rate. If such spread disappears (i.e., if LIBOR plus      % exceeds the related
Weighted Average Net Mortgage Rate), then the Class A Pass-Through Rate for such
Distribution Date will be limited to such lower Weighted Average Net Mortgage
Rate.
 
     The maximum Mortgage Rates range from      % to      % per annum and the
weighted average maximum Mortgage Rate for the Mortgage Loans (by Cut-Off Date
Principal Balance) is equal to      %.
 
WEIGHTED AVERAGE LIFE OF THE CLASS A CERTIFICATES
 
     The following information is given solely to illustrate the effect of
prepayments of the Mortgage Loans on the weighted average life of the Class A
Certificates under the stated assumptions and is not a prediction of the
prepayment rate that might actually be experienced by the Mortgage Loans.
 
     Weighted average life refers to the average amount of time from the date of
issuance of a security until each dollar of principal of such security will be
repaid to the investor. The weighted average lives of the Class A Certificates
will be affected by the rate at which principal on the Mortgage Loans is paid.
Principal payments on Mortgage Loans may be in the form of scheduled
amortization or prepayments (for this purpose, the term "prepayment" includes
prepayments and liquidations due to default or other dispositions of Mortgage
Loans). Prepayments on mortgage loans may be measured by a prepayment standard
or model. The model used in this Prospectus Supplement is a Constant Prepayment
Rate ("CPR"). The CPR represents an assumed constant rate of prepayment each
month, expressed as a per annum percentage of the scheduled principal balance of
the pool of mortgage loans for that month. As used in the following table, the
column headed "0%" assumes that none of the Mortgage Loans is prepaid before
maturity. The columns headed "10%," "15%," "18%," "20%," "23%" and "30%" assume
that prepayments on the Mortgage Loans are made at CPRs of "10%," "15%," "18%,"
"20%," "23%" and "30%," respectively. THE CPR DOES NOT
                                      S-22
<PAGE>   30
 
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.
 
     There is no assurance, however, that prepayments of the Mortgage Loans will
conform to any level of CPR, and no representation is made that the Mortgage
Loans will prepay at the CPRs shown or any other prepayment rate. The rate of
principal payments on pools of mortgage loans is influenced by a variety of
economic, geographic, social and other factors, including the level of interest
rates and the rate at which homeowners sell their homes or default on their
mortgage loans. Other factors affecting prepayment of mortgage loans include
changes in borrowers' housing needs, job transfers, unemployment and obligors'
net equity in their homes.
 
     The percentages and weighted average lives in the following table were
determined assuming that (i) scheduled interest and principal payments on the
Mortgage Loans are received in a timely manner and prepayments are made at the
indicated CPRs; (ii) with respect to each table, principal prepayments on the
Mortgage Loans will be received on the last day of each month commencing in
               1999 at the respective constant percentages of CPR set forth in
such table and there are no Prepayment Interest Shortfalls; (iii) neither the
Master Servicer nor the Certificate Insurer exercises its right of optional
termination described above; (iv) each Mortgage Loan will pay interest only for
the first        years from origination and will fully amortize during the
following fifteen years; (v) each Mortgage Loan will, as of the Cut-Off Date,
have an original term to maturity of        months and the applicable remaining
term to maturity specified below; (vi) each Mortgage Loan bears interest at the
applicable current Mortgage Rate specified in the table below for the number of
months specified in the table below and thereafter bears interest at the sum of
the applicable Index and Margin specified in the table below; (vii) there are no
losses or delinquencies on the Mortgage Loans; (viii) the Class A Certificates
are issued on                , 1999; (ix) the Distribution Date is the 25th day

Loans are converted to fixed rate Mortgage Loans or to different Indices. No
representation is made that the actual losses and delinquencies on the Mortgage
Loans will be experienced at the assumed rate or at any other rate. In addition,
the Mortgage Loans are assumed to have the following characteristics:

     Since the table was prepared on the basis of the assumptions in the
preceding paragraph, there are discrepancies between the characteristics of the
actual Mortgage Loans and the characteristics of the Mortgage Loans assumed in
preparing the tables. Any such discrepancy may have an effect upon the
percentages of the Original Class A Principal Balance outstanding and the
weighted average lives of the Class A Certificates set forth in the tables. In
particular, the Mortgage Rates are adjustable and will most likely vary from the
assumed interest rates, which may have a significant effect on the percentages
of the Original Class A Principal Balance outstanding and the weighted average
life. In addition, since the actual Mortgage Loans in the Trust Fund have
characteristics which differ from those assumed in preparing the tables set
forth below, the distributions of principal on the Class A Certificates may be
made earlier or later than as indicated in the table.
 
     It is not likely that the Mortgage Loans will prepay at any constant CPR to
maturity or that all Mortgage Loans will prepay at the same rate. In addition,
the diverse remaining terms to maturity of the Mortgage Loans could produce
slower distributions of principal than as indicated in the related tables at the
various
 
                                      S-23
<PAGE>   31
 
CPRs specified even if the weighted average remaining term to maturity of the
Mortgage Loans is as assumed above.
 
     Investors are urged to make their investment decisions on a basis that
includes their determination as to anticipated prepayment rates under a variety
of the assumptions discussed herein.
 
     Based on the foregoing assumptions, the following table indicates the
resulting weighted average lives of the Class A Certificates and sets forth the
percentage of the Original Class A Principal Balance that would be outstanding
after each of the dates shown at the indicated CPR.

- ---------------
 
(1) The weighted average life of an Offered Certificate is determined by (i)
    multiplying the amount of each principal distribution by the number of years
    from the date of the issuance of such Certificate to the related
    Distribution Date, (ii) adding the results and (iii) dividing the sum by the
    original principal balance of such Certificate.
 
                        DESCRIPTION OF THE CERTIFICATES
 
     The Certificates will be issued pursuant to the Agreement among the
Depositor, the Master Servicer and the Trustee. A copy of the Agreement
(exclusive of the list of Mortgage Loans) will be attached as an exhibit to the
Current Report on Form 8-K to be filed with the Securities and Exchange
Commission after the date of delivery of the Certificates. Reference is made to
the Prospectus for additional information regarding the terms and conditions of
the Agreement to the extent not revised by the following description. To the
extent
 
                                      S-24
<PAGE>   32
 
that the statements in this Prospectus Supplement modify statements in the
Prospectus, the statements in this Prospectus Supplement control.
 
     The following summaries do not purport to be complete and are subject to,
and are qualified in their entirety by reference to, the provisions of the
Agreement. When particular provisions or terms used in the Agreement are
referred to, the actual provisions (including definitions of terms) are
incorporated by reference.
 
GENERAL
 
     Exclusive of the interest of the Class R Certificates, the Class A
Certificates will initially evidence in the aggregate a beneficial interest of
approximately      % in the pool of Mortgage Loans, and the Class B Certificates
(the "Class B Certificates") will initially evidence the remaining approximate
     %. The Class R Certificates (the "Class R Certificates") do not have a
principal balance.
 
     The Class A Certificates will be issued in fully registered form only, in
denominations of $25,000 and integral multiples of $1,000 in excess thereof. The
"Percentage Interest" of a Class A Certificate is the percentage obtained from
dividing its denomination by the Original Class A Principal Balance. Definitive
Class A Certificates, if issued, will be transferable and exchangeable at the
corporate trust office of the Trustee at its Corporate Trust Department in
California or, if it so elects, at the office of an agent in New York City. No
service charge will be made for any registration of exchange or transfer, but
the Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge.
 
     Distributions of principal and interest on the Class A Certificates will be
made on the 25th day of each month, or, if such day is not a business day, the
next succeeding business day (each, a "Distribution Date") beginning in
               1999 to the persons in whose names the Class A Certificates are
registered at the close of business on the last business day preceding the
immediately preceding Distribution Date or on the date of the initial issuance
of the Certificates in the case of the first Distribution Date (the "Record
Date"). The Class A Certificates will initially be represented by certificates
registered in the name of Cede & Co. ("Cede") as the nominee of The Depository
Trust Company ("DTC"). See "Registration of Class A Certificates" below. If
definitive Class A Certificates are issued, distributions will be made by check
mailed to the address of the person entitled thereto as it appears on the
Certificate Register, except that a Certificateholder who holds Class A
Certificates with original denominations aggregating at least $5 million may
request payment by wire transfer of funds pursuant to written instructions
delivered to the Trustee at least ten business days prior to the Record Date.
The final distribution in retirement of Class A Certificates will be made only
upon presentation and surrender of the Class A Certificates at the office or
agency of the Trustee specified in the final distribution notice to Class A
Certificateholders.
 
     The Collection Account will be established by the Master Servicer in the
name of and on behalf of the Trustee.
 
DISTRIBUTIONS ON THE CERTIFICATES
 
     Distributions of interest and principal to each Holder of a Class A
Certificate will be made on each Distribution Date, commencing in
               1999 in an amount equal to each such Holder's respective
Percentage Interest multiplied by the amount distributed in respect of Class A
Certificates. Certain calculations with respect to the Certificates will be made
by the Master Servicer on the fifth day of the month (or if such fifth day is
not a business day, then on the next preceding business day) (the "Determination
Date"). Distributions on the Class A Certificates will be applied first to
interest and then to principal. All calculations of interest on the Certificates
will be made on the basis of the actual number of days in the Accrual Period
divided by 360. Interest will accrue with respect to each Distribution Date
during the one-month period beginning on the 25th day of the month preceding the
month of such Distribution Date (or, in the case of the first Distribution Date,
beginning on           , 1999) and ending on the 14th day of the month of such
Distribution Date (each, an "Accrual Period").
 
                                      S-25
<PAGE>   33
 
     With respect to each Distribution Date, the Available Distribution Amount
will be the amount received in respect of the Mortgage Loans that is on deposit
in the Collection Account as of the close of business on the related
Determination Date plus the Advances deposited in the Distribution Account
(described below) for such Distribution Date, less the following amounts:
 
          (a) amounts received on particular Mortgage Loans as late payments or
     other recoveries of interest or principal (including Liquidation Proceeds,
     Insurance Proceeds and condemnation awards) and respecting which the Master
     Servicer previously made an unreimbursed Advance of such amounts;
 
          (b) amounts representing the reimbursement for Nonrecoverable Advances
     and other amounts (including the Servicing Fee) permitted to be withdrawn
     by the Master Servicer from, or not required to be deposited in, the
     Collection Account;
 
          (c) amounts representing all or part of a Monthly Payment due after
     the immediately preceding Due Date;
 
          (d) all Repurchase Proceeds, Principal Prepayments, Liquidation
     Proceeds, Insurance Proceeds and condemnation awards with respect to
     Mortgage Loans received after the related Principal Prepayment Period, and
     all related payments of interest representing interest for any period of
     time after the related Due Date; and
 
          (e) all income from Eligible Investments held in the Collection
     Account for the account of the Master Servicer.
 
     On each Distribution Date the Available Distribution Amount will be
deposited into the Distribution Account. In addition, on or before each
Distribution Date, the Trustee will deposit into the Distribution Account (i)
the payments, if any, it has received under the Certificate Insurance Policy and
(ii) any Reserve Fund draw amounts, in each case for distribution on such
Distribution Date.
 
     On each Distribution Date the Available Distribution Amount will be
distributed in the following amounts and order of priority:
 
          (i) to the Class A Certificateholders, interest for the related
     Accrual Period at the Class A Pass-Through Rate on the Class A Principal
     Balance, together with any previously undistributed shortfalls in required
     distributions of interest on the Class A Certificates (the "Class A Unpaid
     Interest Shortfall"). Interest distributions are subject to reduction on
     account of Net Interest Shortfalls as described below;
 
          (ii) the Class A Formula Principal Distribution Amount to the Class A
     Certificateholders on account of principal until the Class A Principal
     Balance is reduced to zero;
 
          (iii) to the Certificate Insurer, the monthly premium due on the
     Certificate Insurance Policy;
 
          (iv) [intentionally omitted]
 
          (v) to the Certificate Insurer, an amount equal to any previously
     unreimbursed payments made under the Certificate Insurance Policy and any
     fees and expenses owed to it under the related insurance agreement,
     together with interest thereon (collectively, the "Unreimbursed Insurer
     Amounts");
 
          (vi) to the Reserve Fund, the amount (but not in excess of the Formula
     Excess Interest Amount) required to be deposited in the Reserve Fund;
 
          (vii) to the Class B Certificateholders, interest for the related
     Accrual Period at the Class B Pass-Through Rate on the Class B Principal
     Balance, together with any previously undistributed shortfalls in required
     distributions of interest on the Class B Certificates;
 
          (viii) on account of principal, to the Class A Certificateholders, the
     Unrecovered Principal Amounts, if any, for the Mortgage Loans for such
     Distribution Date and all prior Distribution Dates that have not previously
     been distributed pursuant to this clause until the Class A Principal
     Balance is reduced to zero;
 
                                      S-26
<PAGE>   34
 
          (ix) to the Class B Certificateholders on account of principal the
     Class B Formula Principal Distribution Amount until the Class B Principal
     Balance is reduced to zero;
 
          (x) to the Class B Certificateholders, the Class B Loss Amounts not
     previously distributed to them pursuant to this clause; and
 
          (xi) any remaining balance to the Class R Certificateholders.
 
     As to any Distribution Date, the "Formula Principal Distribution Amount" is
the sum of:
 
          (a) the principal portion of all Monthly Payments, whether or not
     received, which were due on the related Due Date on Outstanding Mortgage
     Loans as of the related Due Date;
 
          (b) with respect to each Mortgage Loan, all Principal Prepayments made
     by the Mortgagor during the month (the "Principal Prepayment Period")
     preceding the month of such Distribution Date;
 
          (c) with respect to each Mortgage Loan not described in (e) below, all
     Insurance Proceeds, condemnation awards and any other cash proceeds from a
     source other than the Mortgagor, to the extent required to be deposited in
     the Collection Account pursuant to the Agreement, which are allocable to
     principal and were received during the related Principal Prepayment Period,
     net of related unreimbursed Servicing Advances;
 
          (d) with respect to each Mortgage Loan that has been repurchased
     pursuant to Section 11.01 of the Agreement during the related Principal
     Prepayment Period, an amount equal to the Principal Balance of the Mortgage
     Loan as of the date of repurchase;
 
          (e) with respect to each Mortgage Loan that became a Liquidated
     Mortgage Loan during the related Principal Prepayment Period, the amount
     allocable to the principal of such Liquidated Mortgage Loan that was
     recovered out of the net liquidation proceeds in respect of such Liquidated
     Mortgage Loan in such Principal Prepayment Period;
 
          (f) with respect to each Mortgage Loan repurchased during the related
     Principal Prepayment Period by the Master Servicer on account of a breach
     of a representation or warranty that materially adversely affects the
     interests of the Certificateholders or the Certificate Insurer, or on
     account of its conversion to a fixed rate Mortgage Loan or to a new Index,
     an amount equal to the principal portion of the Purchase Price (exclusive
     of any portion thereof included in clause (a) above); and
 
          (g) any previously undistributed shortfall in the distribution of
     amounts in clauses (a) through (f) of the Formula Principal Distribution
     Amount for a prior Distribution Date.
 
     The "Scheduled Formula Principal Distribution Amount" for a Distribution
Date is the amount specified in clause (a) of this paragraph for such
Distribution Date. The "Unscheduled Formula Principal Distribution Amount" for a
Distribution Date is the sum of the amounts in clauses (b), (c), (d), (e) and
(f) of this paragraph for such Distribution Date.
 
     The "Unrecovered Principal Amount" in respect of a Liquidated Mortgage Loan
is the portion, if any, of the principal of such Liquidated Mortgage Loan that
was not recovered upon its liquidation. An Unrecovered Principal Amount in
respect of a Distribution Date is one that was incurred in the immediately
preceding Principal Prepayment Period.
 
     An "Outstanding Mortgage Loan" in respect of a Due Date is a Mortgage Loan
which was not the subject of a Principal Prepayment in full prior to such Due
Date, which did not become a Liquidated Mortgage Loan prior to such Due Date and
which was not repurchased on account of certain breaches of a representation or
warranty or conversion prior to such Due Date.
 
     The "Principal Balance" of a Mortgage Loan is its principal balance
remaining to be paid at the close of business on the Cut-Off Date (after
deduction of all principal payments due on or before the Cut-Off Date whether or
not paid, but without deducting Monthly Payments due after the Cut-Off Date and
received on or before the Cut-Off Date) reduced by all amounts (including
Advances, if any) distributed to Certificateholders relating to principal of
such Mortgage Loan.

<PAGE>   35
 
     The interest entitlement above for the Class A and Class B Certificates
with respect to each Distribution Date will be reduced by the amount of Net
Interest Shortfall allocable to each such Class. The Net Interest Shortfall on
any Distribution Date will be allocated pro rata among the Class A and Class B
Certificates based on the amount of interest each such Class of Certificates
would otherwise be entitled to receive on such Distribution Date.
 
     The "Net Interest Shortfall" in respect of a Distribution Date 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 Relief Act Reduction
and (ii) any Net Prepayment Interest Shortfall. The "Net Prepayment Interest
Shortfall" in respect of a Distribution Date is the aggregate of the Prepayment
Interest Shortfalls incurred on the Mortgage Loans in the preceding Principal
Prepayment Period that were not made up by the application of the Servicing Fees
collected by the Master Servicer in respect of such Principal Prepayment Period.
A "Relief Act Reduction" is a reduction in the amount of monthly interest on a
Mortgage Loan pursuant to the Soldiers' and Sailors' Civil Relief Act of 1940,
as amended.
 
     In no event will the aggregate distributions of principal to the Holders of
the Class A or Class B Certificates (whether out of Available Distribution
Amounts, Reserve Fund draw amounts or payments under the Certificate Insurance
Policy) exceed the Original Principal Balance of such Class.
 
     The "Formula Excess Interest Amount" in respect of a Distribution Date is
the amount, if any, by which (i) one month's interest at the Weighted Average
Net Mortgage Rate for Loan on the aggregate Principal Balance of the Mortgage
Loans as of the beginning of the preceding month (giving effect to the scheduled
principal payments due on such Due Date and unscheduled principal payments
received prior to such Due Date) exceeds (ii) interest for the related Accrual
Period at the weighted average of the Class A and Class B Pass-Through Rates for
such Distribution Date on the aggregate Principal Balance of such Certificates.
 
     The Class A Principal Balance is the Original Class A Principal Balance
less all prior distributions to Class A Certificateholders, on account of
principal.
 
     The Class B Principal Balance, which shall not be less than zero, is the
Original Class B Principal Balance less the sum of (i) all prior distributions
to the Class B Certificateholders on account of principal and (ii) the sum of
all Class B Loss Amounts for prior Distribution Dates. A "Class B Loss Amount"
for a Distribution Date is the amount, if any, by which (a) the sum of (x) the
Formula Principal Distribution Amount (exclusive of the amount in clause (g) of
the definition thereof) and (y) the aggregate of the Unrecovered Principal
Amounts, if any, for such Distribution Date exceeds (b) the amount distributed
on account of principal to the Holders of the Certificates on such Distribution
Date. Class B Loss Amounts will not bear interest.
 
     The term "Principal Balance," when used in respect of a Class or Classes of
Certificates, refers to the principal balance thereof as calculated in the
preceding two paragraphs.
 
     The "Class A Formula Principal Distribution Amount" for a Distribution Date
is equal to the sum of (i) the Class A Percentage of the Scheduled Formula
Principal Distribution Amount and (ii) the Class A Prepayment Percentage of the
Unscheduled Formula Principal Distribution Amount.
 
     The "Class A Percentage" for a Distribution Date is equal to the percentage
(which shall in no event be greater than 100%) derived from dividing the Class A
Principal Balance by the pool scheduled principal balance (the "Pool Scheduled
Principal Balance") (before giving effect to the Formula Principal Distribution
Amount for such Distribution Date). The "Class A Prepayment Percentage" for a
Distribution Date on or before the Distribution Date in                2004 will
be 100%. The "Class A Prepayment Percentage" for a Distribution Date after the
Distribution Date in                2004 will be as follows: for any
Distribution Date subsequent to                2004 to and including the
Distribution Date in                2005, the Class A Percentage for such
Distribution Date plus 70% of the Subordinated Percentage for such Distribution
Date; for any Distribution Date subsequent to                2005 to and
including the Distribution Date in                2006, the Class A Percentage
for such Distribution Date plus 60% of the Subordinated Percentage for such
Distribution Date; for any Distribution Date subsequent to                2006
to and including the Distribution Date in                2007, the Class A
Percentage for such Distribution Date
                                      S-28
<PAGE>   36
 
plus 40% of the Subordinated Percentage for such Distribution Date; for any
Distribution Date subsequent to                2007 to and including the
Distribution Date in                2008, the Class A Percentage for such
Distribution Date plus 20% of the Subordinated Percentage for such Distribution
Date; and for any Distribution Date thereafter, the Class A Percentage for such
Distribution Date (unless on any of the foregoing Distribution Dates the Class A
Percentage exceeds the initial Class A Percentage, in which case the Class A
Prepayment Percentage for such Distribution Date will once again be 100%).
Reduction of the Class A Prepayment Percentage in accordance with the preceding
sentence is subject to the satisfaction of certain criteria regarding
delinquency and loss experience of the Mortgage Loans.
 
     Notwithstanding the foregoing, if on any Distribution Date (i) the Current
Subordination Level equals at least twice the Original Subordination Level, (ii)
cumulative Realized Principal Losses with respect to the Mortgage Loans have not
exceeded      % of the initial Class B Principal Balance, and (iii) over the
prior six months, the average aggregate outstanding principal balance of the
Mortgage Loans delinquent 60 days or more (including for this purpose any
Mortgage Loans in foreclosure and Mortgage Loans with respect to which the
related Mortgage Property has been acquired by the Trust Fund) has not exceeded
     % of the average aggregate outstanding principal balance of all Mortgage
Loans, then the Class A Prepayment Percentage for such Distribution Date will be
as follows: (A) as to any Distribution Date prior to the third anniversary of
the first Distribution Date, the Class A Percentage for such Distribution Date
plus 50% of the Subordinated Percentage for such Distribution Date; and (B) as
to any Distribution Date thereafter, the Class A Percentage for such
Distribution Date.
 
     The "Current Subordination Level" in respect of a Distribution Date is the
percentage derived from dividing (i) the Class B Principal Balance (before
giving effect to the distributions and the allocation of the Unrecovered
Principal Amounts for such Distribution Date) by (ii) the Pool Scheduled
Principal Balance (before giving effect to the Formula Principal Distribution
Amount for such Distribution Date). The "Original Subordination Level" is the
percentage derived from dividing (i) the Original Class B Principal Balance by
(ii) the Original Pool Scheduled Principal Balance, which percentage is      %.
 
     The "Class B Formula Principal Distribution Amount" for a Distribution Date
is the sum of (i) the Subordinated Percentage of the Scheduled Formula Principal
Distribution Amount and (ii) the Subordinated Prepayment Percentage of the
Unscheduled Formula Principal Distribution Amount. The Subordinated Percentage
is equal to 100% less the Class A Percentage. The Subordinated Prepayment
Percentage is equal to 100% less the Class A Prepayment Percentage.
 
     With respect to any Distribution Date, a "Distribution Account Shortfall"
is the sum of (a) the amount, if any, by which (x) the aggregate of the full
amounts due to be distributed pursuant to clauses (i) and (ii) above exceeds (y)
the amount of funds (exclusive of funds representing the Insured Payment in
respect of such Distribution Date) that will be on deposit in the Distribution
Account in respect of such Distribution Date and available to be distributed on
the Class A Certificates, after taking into account all deposits to be made to
the Distribution Account on or prior to such Distribution Date, including
without limitation all Advances, all funds to be transferred from the Reserve
Fund and (b) on the Distribution Date that follows the month in which there
occurs the latest original scheduled maturity date of any Mortgage Loan that was
an Outstanding Mortgage Loan at any time during such month, the amount necessary
to reduce the Class A Principal Balance to zero (after giving effect to all
other distributions of principal to be made on such Distribution Date in respect
of the Class A Certificates). Subject to the terms and conditions of the
Certificate Insurance Policy, the Insured Amount for a Distribution Date will
include the Distribution Account Shortfall, if any, for such Distribution Date.
See "The Certificate Insurance Policy and the Certificate Insurer" herein.
 
     The Class A Pass-Through Rate (the "Class A Pass-Through Rate") for a
Distribution Date will be equal to LIBOR (as described below) plus      %
subject to the following limitation. If the Class A Pass-Through Rate for a
Distribution Date so calculated on the basis of LIBOR is greater than the
Weighted Average Net Mortgage Rate for the Mortgage Loans applicable at the
beginning of the preceding month (after giving effect to the Monthly Payments
due on such Due Date and unscheduled principal payments received prior to such
Due Date), then the Class A Pass-Through Rate, for such Distribution Date will
equal such lower Weighted Average Net Mortgage Rate. The Class B Pass-Through
Rate will be similarly
 
                                      S-29
<PAGE>   37
 
calculated, but will equal LIBOR plus      % subject to the same limitation of
the related Weighted Average Net Mortgage Rate. The "Net Mortgage Rate" of a
Mortgage Loan is its Mortgage Rate less the sum of (i) the Servicing Fee Rate of
     % and (ii) the Certificate Insurance Policy annual premium rate (which,
together with the Servicing Fee Rate, will not exceed      %). The "Weighted
Average Net Mortgage Rate" is the weighted average of the Net Mortgage Rates for
the Mortgage Loans. Notwithstanding the foregoing, the      % margin added to
the applicable LIBOR formula for the calculation of the Class A Pass-Through
Rate will instead be      % for each Distribution after the first Distribution
Date in respect of which the option to purchase the Mortgage Loans, described
under "Description of the Certificates -- Option Termination," may first be
exercised by the Master Servicer. The Class A Pass-Through Rate thus calculated
will still be subject to the limitation of the Weighted Average Net Mortgage
Rate as described above in this paragraph.
 
     Calculation of LIBOR.  LIBOR with respect to any Distribution Date shall be
established by the Trustee and shall equal the arithmetic mean (rounded, if
necessary, to the nearest one-sixteenth of a percent, with a one thirty-second
being rounded upwards) of the offered rates for United States dollar deposits
for one month which appear on the Reuters Screen LIBO Page (as defined below) as
of 11:00 a.m., London time, on the second LIBOR Business Day prior to the
immediately preceding Distribution Date (but as of           , 1999, in the case
of the Distribution Date on           15, 1999); provided that at least two such
offered rates appear on the Reuters Screen LIBO Page on such date. If fewer than
two offered rates appear, LIBOR will be determined on such date as described in
the paragraph below. "Reuters Screen LIBO Page" means the display designated as
page "LIBO" on the Reuters Monitor Money Rates Service (or such other page as
may replace the LIBO page on that service for the purpose of displaying London
interbank offered rates of major banks). "LIBOR Business Day," for purposes of
the Agreement, is a day which is both a Business Day (as defined in the
Agreement) and a day on which banking institutions in the City of London,
England are not required or authorized by law to be closed.
 
     If on such date fewer than two offered rates appear on the Reuters Screen
LIBO Page, the Trustee will request the principal London office of each of the
Reference Banks (which shall be major banks specified in, or determined by the
Master Servicer under, the Agreement that are engaged in transactions in the
London interbank market) to provide the Trustee with its offered quotation for
United States dollar deposits for one month to prime banks in the London
interbank market as of 11:00 a.m., London time, on such date. If at least two
Reference Banks provide the Trustee with such offered quotations, LIBOR on such
date will be the arithmetic mean (rounded, if necessary, to the nearest
one-sixteenth of a percent, with a one thirty-second being rounded upwards) of
all such quotations. If on such date fewer than two of the Reference Banks
provide the Trustee with such an offered quotation, LIBOR on such date will be
the arithmetic mean (rounded, if necessary, to the nearest one-sixteenth of a
percent, with a one thirty-second being rounded upwards) of the offered per
annum rates which one or more leading banks in The City of New York specified in
or determined by the Agreement are quoting as of 11:00 a.m., New York City time,
on such date to leading European banks for United States dollar deposits for one
month; provided, however, that if such banks are not quoting as described above,
LIBOR will be the LIBOR applicable to the immediately preceding Distribution
Date.
 
RESERVE FUND
 
     The Reserve Fund (the "Reserve Fund") will be an account established with
the Trustee and will initially be funded up to $          from the application
in the aggregate of the Available Distribution Amount pursuant to clause (vi)
under "Distributions on the Certificates" above. On each Distribution Date,
funds, if any, in the Reserve Fund will be applied in the following order of
priority: (i) to make any required Advance that the Master Servicer fails to
make, (ii) to distribute any shortfall in the amount required to be distributed
to the Class A Certificateholders on such Distribution Date, (iii) to pay to the
Certificate Insurer the premium on the Certificate Insurance Policy for such
Distribution Date to the extent not paid under "Distributions on the
Certificates" above and (iv) to pay to the Certificate Insurer any Unreimbursed
Insurer Amounts for such Distribution Date to the extent not paid under
"Distributions on the Certificates" above. Collections of late Monthly Payments
covered by any Advance from the Reserve Fund will be applied to reinstate the
amount in the Reserve Fund up to $          . Similarly, the application of the
Available Distribution Amount pursuant to clause (vi) under "Distributions on
the Certificates" above may reinstate the
 
                                      S-30
<PAGE>   38
 
amount in the Reserve Fund up to $          . If the amount available in the
Reserve Fund on a Distribution Date is not sufficient to pay the entire amount
of shortfalls referred to in clauses (i) and (ii) in this paragraph, the amount
of such deficiency shall be allocated pro rata among the Class A Certificates on
the basis of their respective Principal Balances prior to such Distribution
Date. Notwithstanding the foregoing, the aggregate amount distributed from the
Reserve Fund pursuant to clause (ii) of this paragraph over the life of the
Trust Fund shall not exceed $          . If an aggregate of $          has been
applied pursuant to clause (ii) of this paragraph, then the Reserve Fund may be
reinstated one time up to $          from the application of the Available
Distribution Amount pursuant to clause (vi) under "Distributions on the
Certificates" above, and funds, if any, in the Reserve Fund may thereafter be
applied only pursuant to clause (i) of this paragraph.
 
SUBORDINATED CERTIFICATES
 
     The rights of the Class B Certificateholders and the Class R
Certificateholders to receive distributions with respect to the Mortgage Loans
will be subordinated to the rights of the Holders of Class A Certificates to the
extent described herein. This subordination is intended to enhance the
likelihood of regular receipt by the Holders of Class A Certificates of the full
amount of monthly distributions due them and to protect the Holders of Class A
Certificates against losses.
 
     The protection afforded to the Holders of the Class A Certificates by means
of the subordination, to the extent provided herein, of the Class B and Class R
Certificates as described above will be accomplished (i) by the application of
the Available Distribution Amount in the order specified under "Distributions on
the Certificates" above and (ii) if the Available Distribution Amount on such
Distribution Date is not sufficient to permit the distribution of the entire
Class A Formula Principal Distribution Amount and all previously undistributed
Unrecovered Principal Amounts to the Holders of Class A Certificates, by the
right of the Holders of such Class A Certificates to receive any such shortfall
out of future distributions of Available Distribution Amounts that would
otherwise have been payable to the Holders of the related Class B Certificates
and the Class R Certificates, as applicable. This subordination feature is
effected for the Class A Certificates by allocating principal among the
Certificates on a shifting-interest payment basis as described herein.
 
     As described above, the distribution of principal to the Holders of Class A
Certificates is intended to include the principal balance of each Mortgage Loan
that became a Liquidated Mortgage Loan during the related Principal Prepayment
Period. A "Liquidated Mortgage Loan" is, generally, a defaulted Mortgage Loan as
to which all amounts that the Master Servicer believes can be recovered with
respect to such Mortgage Loan or the property acquired in respect thereof have
been recovered. If the Liquidation Proceeds, net of related Liquidation Expenses
and any Advances in respect thereof, from such Liquidated Mortgage Loan are less
than the principal balance of such Liquidated Mortgage Loan, the deficiency may,
in effect, be absorbed by the Holders of the Class B Certificates since a
portion of future Available Distribution Amounts funded by future principal
collections on the Mortgage Loans, up to the aggregate amount of such
deficiencies, that would otherwise have been distributable to them may be paid
to the Holders of the Class A Certificates or to the Certificate Insurer. No
assurance can be given that the Class A Certificates will not experience any
losses.
 
     If, due to losses and delinquencies, the Available Distribution Amount for
any Distribution Date is not sufficient to cover, in addition to interest
distributable to the Holders of the Class A Certificates, the entire Formula
Principal Distribution Amount and any Unrecovered Principal Amounts
distributable to the Holders of such Class A Certificates on such Distribution
Date, then the aggregate of the Pool Scheduled Principal Balance will have
become less than the outstanding Principal Balance of the Certificates. Such
disproportionate reduction reduces the protection afforded by the subordination
of the Class B Certificates. Consequently, but for the effect of the Certificate
Insurance Policy, the Holders of Class A Certificates will bear all losses and
delinquencies on the Mortgage Loans, and could incur losses on their investment,
if the Pool Scheduled Principal Balance becomes equal to or less than the
aggregate outstanding Principal Balance of such Class A Certificates.
 
                                      S-31
<PAGE>   39
 
CERTIFICATE INSURANCE POLICY
 
     The Depositor will obtain the certificate insurance policy (the
"Certificate Insurance Policy"), which will be issued by the Certificate Insurer
in favor of the Trustee and will provide for payment of Insured Amounts (as
defined herein) in accordance with the terms of the Certificate Insurance Policy
solely for the benefit of the Holders of the Class A Certificates. The
Certificate Insurance Policy is non-cancelable. See "The Certificate Insurance
Policy and the Certificate Insurer" herein.
 
     The Certificate Insurer is required to pay Insured Amounts to the Trustee
as paying agent on the later of the applicable Distribution Date or the Business
Day next following the Business Day on which the Certificate Insurer receives a
notice of Nonpayment (as defined herein) in accordance with and subject to the
terms of the Certificate Insurance Policy. The Certificate Insurer is not
responsible for the application of any Insured Amount subsequent to the receipt
thereof by the Trustee.
 
     The Certificate Insurance Policy does not cover shortfalls, if any,
attributable to the liability of the Trust Fund, the REMIC or the Trustee for
withholding taxes, if any (including interest and penalties in respect of any
such liability). In addition, the Certificate Insurance Policy does not protect
against the adverse consequences of, and does not guarantee, any specified rate
of prepayments nor protect against any risk other than Nonpayment, including
failure of the Trustee to make any Insured Payment due to Holders of the Class A
Certificates. In addition, the Certificate Insurance Policy does not cover any
Net Interest Shortfalls in respect of the Class A Certificates. The Certificate
Insurer has the right to terminate the Trust Fund, causing the transfer of
amounts in certain accounts and the acceleration of the Class A Certificates,
under certain circumstances if the Pool Scheduled Principal Balance becomes
equal to or less than 10% of the Pool Scheduled Principal Balance as of the
Cut-Off Date.
 
ASSIGNMENT OF MORTGAGE LOANS
 
     The Depositor will cause the Mortgage Loans to be assigned to the Trustee,
together with all principal and interest collected on or with respect to the
Mortgage Loans and due after the Cut-Off Date. The Trustee will, concurrently
with such assignment, authenticate and deliver the Certificates. Each Mortgage
Loan will be identified in a schedule appearing as an exhibit to the Agreement
(the "Mortgage Loan Schedule"). The Mortgage Loan Schedule specifies, among
other things, with respect to each Mortgage Loan, the original principal amount
and the unpaid principal balance as of the Cut-Off Date; the Monthly Payment as
of the Cut-Off Date; the months remaining to maturity of the Mortgage Loan; the
Margin; and the Mortgage Rate as of the Cut-Off Date.
 
     The Mortgage Notes and Mortgages and certain other documents (the "Mortgage
Files") will be delivered by the Master Servicer to the Trustee or a custodian
of the Trustee within 21 days after the date of the initial issuance of the
Certificates, and at least 50% of the Mortgage Notes will have been delivered by
such issuance date. The Trustee, or its custodian, will review each Mortgage
File (or copies thereof) and if any document required to be included in any
Mortgage File is found to be defective in any material respect and such defect
is not cured within 60 days (or such longer period as may be agreed to by the
Trustee) following notification thereof to the Master Servicer by the Trustee,
the Master Servicer will repurchase or substitute for such Mortgage Loan in the
manner set forth under "The Pooling and Servicing Agreement -- Assignment of
Mortgage Assets -- Assignment of the Mortgage Loans" in the Prospectus and as
set forth in the Agreement.
 
     The assignments of the Mortgages to the Trustee will not be recorded.
 
AMENDMENTS TO MORTGAGE LOAN DOCUMENTS
 
     In connection with the servicing of the Mortgage Loans, the Master Servicer
may at the request of a borrower or at its own initiative agree to modify the
Mortgage Note or Mortgage relating to a Mortgage Loan or waive compliance by the
borrower with any provision of the Mortgage Note or Mortgage, provided that any
such modification or waiver (i) does not extend the scheduled maturity date of,
modify the interest rate payable under (except as required by law or as
contemplated by the Mortgage Note), or constitute a
 
                                      S-32
<PAGE>   40
 
cancellation or discharge of the outstanding principal balance under such
Mortgage Loan, (ii) is not inconsistent with the Master Servicer's then current
practice respecting comparable mortgage loans held in its own portfolio, or
(iii) does not materially and adversely affect the security afforded by the
Mortgaged Property; provided, however, that the Master Servicer may agree to
changes to the terms of a Mortgage Note or Mortgage which would otherwise be
violative of clauses (i) and (iii) above if (a) the Master Servicer has
determined that such changes are necessary to avoid prepayment of the related
Mortgage Loan as a result of refinancing provided by another lender or to
accommodate the request of a borrower to extend the scheduled maturity date of
the related Mortgage Loan and such changes are consistent with prudent business
practice, (b) the Master Servicer repurchases the related Mortgage Loan for the
Purchase Price on the business day preceding the Distribution Date immediately
following the Principal Prepayment Period during which such changes were made
and (c) such changes and subsequent repurchase will not affect the status of the
Trust Fund as a REMIC as evidenced by an opinion of counsel. Any such repurchase
will be accomplished in the manner described under "Description of the
Certificates -- Assignment of Mortgage Loans" herein.
 
SERVICING AND INSURANCE
 
     The Mortgage Loans will be serviced in accordance with procedures as
described generally in the Prospectus under "The Pooling and Servicing
Agreement" and as set forth in the Agreement.
 
     Except as described below, when any Mortgaged Property is conveyed by the
Mortgagor, the Master Servicer may, but is not obligated to, enforce any
due-on-sale clause contained in the Mortgage Loan, to the extent permitted under
applicable law and governmental regulations. Acceleration of Mortgage Loans as a
result of enforcement of such "due-on-sale" provisions in connection with
transfers of the related Mortgaged Properties will affect the level of
prepayments on the Mortgage Loans, thereby affecting the weighted average life
of the Class A Certificates. See "Yield and Prepayment Considerations" in the
Prospectus and "Prepayment and Yield Considerations" herein. If the Master
Servicer elects not to enforce any due-on-sale clause or is prevented from
enforcing such due-on-sale clause under applicable law, the Master Servicer is
authorized to enter into an assumption and modification agreement with the
person to whom such Mortgaged Property has been or is about to be conveyed,
pursuant to which such person becomes liable under the Mortgage Loan and, to the
extent permitted by applicable law, the borrower remains liable thereon.
 
     The Master Servicer will be obligated to maintain a standard hazard
insurance policy (the "Standard Hazard Insurance Policy") with respect to each
Mortgage Loan in an amount equal to the replacement cost of the improvements
securing such Mortgage Loan or the outstanding principal balance of such
Mortgage Loan, whichever is less. See "The Pooling and Servicing
Agreement -- Hazard Insurance" in the Prospectus. No mortgage pool insurance
policy (the "Mortgage Pool Insurance Policy"), special hazard insurance policy
(the "Special Hazard Insurance Policy") or mortgagor bankruptcy insurance (the
"Mortgagor Bankruptcy Insurance") will be maintained with respect to the
Mortgage Pool, nor will any Mortgage Loan included in the Mortgage Pool be
subject to FHA Insurance or VA Guaranty or be covered by a primary mortgage
insurance policy (the "Primary Mortgage Insurance Policy").
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Master Servicer will be paid a monthly servicing fee (the "Servicing
Fee") (including any sub-servicing compensation) with respect to each Mortgage
Loan in an amount equal to approximately one-twelfth of      % of the principal
balance of each Mortgage Loan (the "Servicing Fee Rate"). The Master Servicer
will not receive excess interest or excess proceeds as additional servicing
compensation. See "Certain Federal Income Tax Consequences" herein and in the
Prospectus.
 
     The Master Servicer is obligated to pay certain ongoing expenses associated
with the Mortgage Pool and incurred by the Master Servicer in connection with
its responsibilities under the Agreement. See "The Pooling and Servicing
Agreement -- Servicing and Other Compensation and Payment of Expenses" in the
Prospectus for information regarding other possible compensation to the Master
Servicer and for information regarding expenses payable by the Master Servicer.
 
                                      S-33
<PAGE>   41
 
     The Servicing Fee in respect of a month will be applied to make up any
Prepayment Interest Shortfall experienced on any prepayment of a Mortgage Loan
in such month in respect of which less than one month's interest is collected in
respect of such month. A "Prepayment Interest Shortfall" in respect of a
Mortgage Loan is the amount by which interest paid by the Mortgagor in
connection with a principal prepayment of such Mortgage Loan is less than one
month's interest at the related Mortgage Rate on the amount prepaid. See
"Prepayment and Yield Considerations." No assurance can be given that the amount
of the Servicing Fee will be sufficient for such purpose.
 
OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS
 
     The Master Servicer may, in its sole discretion, purchase from the Trust
Fund any Mortgage Loan as to which a Monthly Payment is 180 or more days
delinquent. Any such purchase will be at a price equal to 100% of the Principal
Balance of such Mortgage Loan, plus any unreimbursed Advances in respect
thereof, together with accrued interest thereon at the Mortgage Rate from the
date through which interest was last paid by the related borrower or advanced by
the Master Servicer to the end of the Principal Prepayment Period preceding the
Distribution Date on which the proceeds of such purchase are required to be
distributed.
 
ADVANCES
 
     The Master Servicer is obligated to make advances (the "Advances") of cash
each month, which will be part of the Available Distribution Amount, equal to
the amount of the delinquent Monthly Payments due on the immediately preceding
Due Date and not paid. The Master Servicer is under no obligation to make an
Advance with respect to any Mortgage Loan if the Master Servicer determines, in
its sole discretion, that such Advance will not be recoverable from future
payments and collections on such Mortgage Loans based upon its general
experience in servicing mortgage loans, its assessment of the likelihood of
ultimate payment by the related Mortgagors and its estimate of Liquidation
Proceeds. "Liquidation Proceeds" means all proceeds (including Insurance
Proceeds) received in connection with the liquidation of any Mortgage Loan or
related REO or any condemnation or taking by eminent domain, whether through
trustee's sale, foreclosure sale or otherwise (including rental income). The
Master Servicer will be reimbursed for Advances out of the related late
collections and Liquidation Proceeds. The Master Servicer will be reimbursed for
Advances that it determines will not be recoverable out of related late
collections and Liquidation Proceeds ("Non-recoverable Advances") from funds in
the Collection Account. Advances are intended to maintain a regular flow of
scheduled interest payments to the Class A Certificateholders, not to guarantee
or insure against losses. Accordingly, any funds so advanced are recoverable by
the Master Servicer out of amounts received on Mortgage Loans. Advances are
required to be deposited in the Collection Account by the second Business Day
prior to the related Distribution Date. The Master Servicer may make an Advance
(i) out of its own funds, (ii) out of funds in the Collection Account that are
not part of the Available Distribution Amount for the related Distribution Date
or (iii) by any combination of clauses (i) and (ii). Advances made pursuant to
clause (ii) must be restored from the Master Servicer's funds when such amounts
are required to be distributed as part of an Available Distribution Amount.
 
OPTIONAL TERMINATION
 
     The Master Servicer may, at its option, on any Distribution Date,
repurchase from the Mortgage Pool all Mortgage Loans remaining outstanding at
such time as the Pool Scheduled Principal Balance is less than 10% of the Pool
Scheduled Principal Balance as of the Cut-Off Date. The repurchase price to be
distributed to Certificateholders will equal the greater of (i) the aggregate
Principal Balances of the Mortgage Loans plus accrued interest thereon at the
related Net Mortgage Rate, plus the appraised value of any property acquired in
respect of a Mortgage Loan, (ii) the fair market value of the Mortgage Loans and
any property acquired in respect of a Mortgage Loan (as determined by the Master
Servicer) and (iii) the sum of (a) the aggregate of the Class A Principal
Balance together with one month's interest at the Class A Pass-Through Rate and
any Class A Unpaid Interest Shortfall and (b) the sum of the Class B Principal
Balance together with one month's interest at the Class B Pass-Through Rate and
any previously undistributed shortfall in interest due on the Class B
Certificates on prior Distribution Dates. The repurchase price will be
distributed to
 
                                      S-34
<PAGE>   42
 
Certificateholders in the month following the month of repurchase, first to the
Class A Certificateholders to the extent of the amount in clause (iii)(a) and
then in accordance with the Agreement. Under certain circumstances, the
Certificate Insurer may exercise the Master Servicer's right of repurchase.
 
MISCELLANEOUS
 
     In determining the percentage of the Trust Fund evidenced by a Certificate
for purposes of determining the consent of Certificateholders or other action by
Certificateholders as discussed under "The Pooling and Servicing
Agreement -- Amendment" in the Prospectus, such percentage shall be based upon
the relative outstanding Principal Balances of the Certificates. Amendments to
the Agreement requiring the consent of Certificateholders shall require only the
consent of the Holders of Certificates of each Class affected thereby,
evidencing, as to such Class, Percentage Interests aggregating at least 66%.
Amendments to the Agreement may be made only with the prior written consent of
the Certificate Insurer. Certain other actions under the Agreement also require
the prior written consent of the Certificate Insurer. The Certificate Insurer
may direct the Trustee to waive any default by the Master Servicer under the
Agreement, except that a default in making any required distribution on any
Certificate may only be waived by the affected Certificateholder. Upon an Event
of Default, the Trustee may terminate the rights of the Master Servicer only
with the consent of the Certificate Insurer, and shall terminate the Master
Servicer at the direction of the Certificate Insurer.
 
     "Events of Default" will consist of (i)(A) any failure by the Master
Servicer to make any required Monthly Advance or (B) any other failure of the
Master Servicer to deposit in the Collection Account or Distribution Account any
deposit required to be made under the Pooling and Servicing Agreement, which
failure continues unremedied for two Business Days after the giving of written
notice of such failure to the Master Servicer by the Trustee, or to the Master
Servicer and the Trustee by the Certificate Insurer or any Certificateholder;
(ii) any failure by the Master Servicer duly to observe or perform in any
material respect any other of its covenants or agreements in the Pooling and
Servicing Agreement which, in each case, materially and adversely affects the
interests of the Certificateholders or the Certificate Insurer and continues
unremedied for 60 days after the giving of written notice of such failure to the
Master Servicer by the Trustee, or to the Master Servicer and the Trustee by the
Certificate Insurer or any Certificateholder; (iii) any failure by the Master
Servicer to make any required Servicing Advance, which failure continues
unremedied for a period of 30 days aft the giving of written notice of such
failure to the Master Servicer by the Trustee, or to the Master Servicer and the
Trustee by the Certificate Insurer or any Certificateholder; (iv) the loss and
delinquency experience with respect to the Mortgage Loans exceeds certain levels
in the Pooling and Servicing Agreement; or (v) certain events of insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings relating to the Master Servicer and certain actions by the Master
Servicer indicating insolvency, reorganization or inability to pay its
obligations (an "Insolvency Event").
 
     A successor Master Servicer, if any, will become obligated to purchase
Convertible Mortgage Loans that convert to a fixed rate after such successor
becomes the Master Servicer only if such successor Master Servicer, at its
discretion, elects to obligate itself to make such purchases. A terminated
Master Servicer (including the initial Master Servicer) will not be obligated to
make such purchases after its termination as Master Servicer.
 
REGISTRATION OF CLASS A CERTIFICATES
 
     The Class A Certificates will initially be registered in the name of Cede,
the nominee of DTC. DTC 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 New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the 1934 Act. DTC accepts securities for deposit from its participating
organizations ("Participants") and facilitates the clearance and settlement of
securities transactions between Participants in such securities through
electronic book-entry changes in accounts of Participants, thereby eliminating
the need for physical movement of certificates. Participants include securities
brokers and dealers, banks and trust companies and clearing corporations and may
include certain other organizations. Indirect access to the DTC system is also
available to others such as
 
                                      S-35
<PAGE>   43
 
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly.
 
     Certificate owners (the "Certificate Owners") who are not Participants but
desire to purchase, sell or otherwise transfer ownership of Class A Certificates
may do so only through Participants (unless and until Definitive Class A
Certificates, as defined below, are issued). In addition, Certificate Owners
will receive all distributions of principal of and interest on the Class A
Certificates from the Trustee through DTC and Participants. Certificate Owners
will not receive or be entitled to receive certificates representing their
respective interests in the Class A Certificates, except under the limited
circumstances described below.
 
     Unless and until Definitive Class A Certificates (as defined below) are
issued, it is anticipated that the only "Certificateholder" of the Class A
Certificates will be Cede, as nominee of DTC. Certificate Owners will not be
Certificateholders as that term is used in the Agreement. Certificate Owners are
only permitted to exercise the rights of Certificateholders indirectly through
Participants and DTC.
 
     While the Class A Certificates are outstanding (except under the
circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations, DTC is required to make
book-entry transfers among Participants on whose behalf it acts with respect to
the Class A Certificates and is required to receive and transmit distributions
of principal of, and interest on, the Class A Certificates. Unless and until
Definitive Class A Certificates are issued, Certificate Owners who are not
Participants may transfer ownership of Class A Certificates only through
Participants by instructing such Participants to transfer Class A Certificates,
by book-entry transfer, through DTC for the account of the purchasers of such
Certificates, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of Class A Certificates will be executed through DTC and the accounts
of the respective Participants at DTC will be debited and credited.
 
     Class A Certificates will be issued in registered form to Certificate
Owners, or their nominees, rather than to DTC (such Certificates being referred
to herein as "Definitive Class A Certificates"), only if (i) DTC or the
Depositor advises the Trustee in writing that DTC is no longer willing or able
to discharge properly its responsibilities as nominee and depository with
respect to the Class A Certificates and the Depositor or the Trustee is unable
to locate a qualified successor, (ii) the Depositor, at its sole option and with
the consent of the Trustee, elects to terminate the book-entry system through
DTC or (iii) after the occurrence of an Event of Default, DTC, at the direction
of Certificate Owners having a majority in Percentage Interests of the Class A
Certificates together, advises the Trustee in writing that the continuation of a
book-entry system through DTC (or a successor thereto) to the exclusion of any
physical certificates being issued to Certificate Owners is no longer in the
best interest of Certificate Owners. Upon issuance of Definitive Class A
Certificates to Certificate Owners, such Certificates will be transferable
directly (and not exclusively on a book-entry basis) and registered Holders will
deal directly with the Trustee with respect to transfers, notices and
distributions.
 
     DTC has advised the Depositor and the Trustee that, unless and until
Definitive Class A Certificates are issued, DTC will take any action permitted
to be taken by a Holder of Class A Certificates under the Agreement only at the
direction of one or more Participants to whose DTC account the Class A
Certificates are credited. DTC has advised the Depositor that DTC will take such
action with respect to any Percentage Interests of the Class A Certificates only
at the direction of and on behalf of such Participants with respect to such
Percentage Interests of the Class A Certificates. DTC may take actions, at the
direction of the related Participants, with respect to some Class A Certificates
which conflict with actions taken with respect to other Class A Certificates.
 
     Issuance of the Class A Certificates in book-entry form rather than as
physical certificates may adversely affect the liquidity of the Class A
Certificates in the secondary market and the ability of Certificate Owners to
pledge them. In addition, since distributions on the Class A Certificates will
be made by the Trustee to DTC and DTC will credit such distributions to the
accounts of its Participants, which will further credit them to the accounts of
indirect participants of Certificate Owners, Certificate Owners may experience
delays in the receipt of such distributions.

THE TRUSTEE
 
                    will act as Trustee of the Trust Fund. The mailing address
of the Trustee's corporate trust office is                and its telephone
number is                .
 
          THE CERTIFICATE INSURANCE POLICY AND THE CERTIFICATE INSURER
 
     The following information has been supplied by the Certificate Insurer for
inclusion in this Prospectus Supplement.
 
     The Certificate Insurer, in consideration of the payment of the premium and
subject to the terms of the Certificate Insurance Policy, unconditionally and
irrevocably guarantees that an amount equal to each full and complete Insured
Amount (as defined below) will be received by the Trustee for distribution to
Holders of the Class A Certificates in accordance with the terms of the
Agreement (as defined below). The Certificate Insurer's obligations under the
Certificate Insurance Policy with respect to a particular Insured Amount shall
be finally and completely discharged to the extent funds equal to the applicable
Insured Amount are received from the Certificate Insurer by the Trustee. The
Certificate Insurer is not responsible for the application of any Insured Amount
subsequent to the receipt thereof by the Trustee. Insured Amounts shall be paid
only at the time set forth in the Certificate Insurance Policy.
 
     Notwithstanding the foregoing paragraph, the Certificate Insurance Policy
does not cover shortfalls, if any, attributable to the liability of the Trust
Fund, the REMIC or the Trustee for withholding taxes, if any (including interest
and penalties in respect of any such liability). The Certificate Insurance
Policy does not protect against the adverse consequences of, and does not
guarantee, any specified rate of prepayments nor protect against any risk other
than nonpayment, including failure of the Trustee to make any Insured Payment
due to Holders of the Class A Certificates. In addition, the Certificate
Insurance Policy does not cover any Net Interest Shortfalls in respect of the
Class A Certificates.
 
     In the event the Trustee has notice that any payment of principal or
interest which has been made to a Holder of the Class A Certificates by or on
behalf of the Trustee has been deemed a preferential transfer and theretofore
recovered from its registered owner pursuant to the United States Bankruptcy
Code in accordance with a final, nonappealable order of a court of competent
jurisdiction, the Certificate Insurer will make payment to the Trustee in
respect thereof.
 
     The Certificate Insurer will pay any amount payable under the Certificate
Insurance Policy from its own funds on the later of (a) the Business Day next
following the Business Day on which the Certificate Insurer receives a notice of
Nonpayment or (b) the applicable Distribution Date. Such payments shall be made
only upon presentation of an instrument in form and substance satisfactory to
the Certificate Insurer who shall be subrogated to all rights of the Holders of
the Class A Certificates to payment on the Class A Certificates to the extent of
the insurance disbursements so made. Once payments of the Insured Amounts have
been made to the Trustee, the Certificate Insurer shall have no further
obligation in respect of such Insured Amounts.
 
     As used in the Certificate Insurance Policy, the following terms have the
following meanings:
 
          "Agreement" means the Pooling and Servicing Agreement dated as of
               , 1999, by and among the Depositor, the Master Servicer and the
     Trustee without regard to any amendment or supplement thereto without the
     prior consent of the Certificate Insurer.
 
          "Insured Amount" and "Nonpayment" mean with respect to any
     Distribution Date the sum of (i) the Distribution Account Shortfall for
     such Distribution Date and (ii) any Preference Amount.
 
          "Insured Payment" means with respect to any Distribution Date the
     Insured Amounts paid to the Trustee by the Certificate Insurer.
 
          "Preference Amount" means any payment of principal or interest which
     has been made to a Holder of the Class A Certificates by or on behalf of
     the Trustee which has been deemed a preferential transfer and theretofore
     recovered from its registered owner pursuant to the United States
     Bankruptcy Code in accordance with a final, nonappealable order of a court
     of competent jurisdiction.

     The Certificate Insurance Policy is being issued under and pursuant to, and
shall be construed under, the laws of the State of New York, without giving
effect to the conflict of laws principles thereof.
 
     The insurance provided by the Certificate Insurance Policy is not covered
by the Property/Casualty Insurance Security Fund specified in Article 76 of the
New York Insurance Law.
 
     The Certificate Insurance Policy is not cancelable for any reason. The
premiums on the Certificate Insurance Policy are not refundable for any reason
including payment, or provision being made for payment, prior to the maturity of
the Class A Certificates.
 
     The following table sets forth selected financial information on the basis
of generally accepted accounting principles.
 
                        [SELECTED FINANCIAL INFORMATION]
 
     The Certificate Insurer makes no representation regarding Certificates or
the advisability of investing in the Certificates and makes no representation
regarding, nor has it participated in the preparation of, the Prospectus or the
Prospectus Supplemental other than the information supplied by the Certificate
Insurer and presented under the heading "The Certificate Insurer" and in
Appendix A and Appendix B.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a general discussion of the material anticipated federal
income tax consequences of the purchase, ownership and disposition of the
Offered Certificates prepared by Moore & Van Allen, PLLC, counsel to the Seller
("Tax Counsel"). The discussion is based upon the Internal Revenue Code of 1986,
as amended (the "Code"), existing and proposed Treasury regulations thereunder,
including regulations (the "REMIC Regulations" and the "OID Regulations")
promulgated under the real estate mortgage investment conduit and original issue
discount provisions of the Code, published rulings and court decisions, any of
which is subject to change, possibly with retroactive effect. The discussion
does not purport to deal with all federal tax consequences applicable to all
categories of investors, some of whom may be subject to special rules. Investors
should consult their tax advisors in determining the particular federal, state,
local and any other tax consequences to them of the purchase, ownership and
disposition of the Offered Certificates.
 
REMIC ELECTION
 
     Pursuant to the Agreement, the Trustee will elect to treat a portion of the
Trust Fund as one or more REMICs for federal income tax purposes. Qualification
as a REMIC requires ongoing compliance with certain conditions. Tax Counsel will
advise the Seller that, in its opinion, for federal income tax purposes,
assuming (i) the REMIC elections are properly made and (ii) the Agreement is
complied with, a portion of the Trust Fund will be treated as a REMIC, the Class
A Certificates and the Class B Certificates will be treated as regular interests
in the REMIC and the Class R Certificate will be treated as the sole residual
interest in the REMIC. The Class A Certificates and the Class B Certificates
offered hereby are referred to herein as the "Regular Certificates."
 
     The REMIC generally will not be subject to federal income tax except with
respect to any income from prohibited transactions, any "Net Income from
Foreclosure Property", and certain contributions, if any, to the Trust Fund
after the Startup Day (see "-- Taxes That May be Imposed on the Trust Fund"
below).
 
CERTAIN SPECIAL RULES RELATING TO THE REGULAR CERTIFICATES
 
     Regular Certificates held by a thrift institution taxed as a "domestic
building and loan association" will constitute assets described in Section
7701(a)(19)(C) of the Code and Regular Certificates held by a real estate
investment trust will constitute "real estate assets" within the meaning of
Section 856(c)(4)(A) of the Code. If less than 95% of the assets comprising a
REMIC constitute assets qualifying under any of the foregoing sections of the
Code, then the Regular Certificates will be qualifying assets under such
sections only to the extent that the assets comprising the REMIC are qualifying
assets. Owners of Regular Certificates
                                      S-38
<PAGE>   46
 
should be aware that Regular Certificates held by certain financial institutions
will be "evidences of indebtedness" within the meaning of Section 582(c) of the
Code. Interest on the Regular Certificates will be interest described in Section
856(c)(3)(B) of the Code to the extent that the Regular Certificates are treated
as "real estate assets" within the meaning of Section 856(c)(5)(A) of the Code.
Regular Certificates will represent "qualified mortgages," within the meaning of
Section 860G(a)(3) of the Code, for other REMICs and "permitted assets," within
the meaning of Section 860L(c) of the Code, for financial asset securitization
investment trusts.
 
INTEREST; ORIGINAL ISSUE DISCOUNT AND PREMIUM
 
     For federal income tax purposes, regular interests in a REMIC generally are
treated as debt instruments issued by the REMIC, and not as ownership interests
in the REMIC or its assets. Owners of Regular Certificates, including those that
otherwise report income under the cash method of accounting, will be required to
include in income all interest and original issue discount, if any, on such
Certificates in accordance with accrual method of accounting.
 
     The [Class                ] Certificates will be issued with "original
issue discount" ("OID") for federal income tax purposes. The prepayment
assumption that will be used in determining the rate of accrual of OID, and
market discount and premium, if any, for federal income tax purposes is [     %]
of the SPA. No representation is made that the Mortgage Loans will prepay at any
given percentage of the SPA. For federal income tax purposes, owners of Regular
Certificates issued with OID must include in gross income the original issue
discount on such Certificates on an economic accrual basis generally in advance
of the receipt of the cash attributable to such income. Information with respect
to the accrual of OID on Regular Certificates will be reported annually (or more
often, if required) by the Trust Administrator to the Internal Revenue Service
(the "Service") and will also be provided, at such times and in the manner
required by the Service, to owners of such Regular Certificates, and relevant
brokers and middlemen. See "Certain Federal Income Tax Consequences -- REMIC
Certificates -- Regular Certificates" in the Prospectus for a more detailed
discussion of the computation of OID on certain Regular Certificates.
 
     Under current law, it is not entirely clear the manner in which income
should be accrued on Regular Certificates, such as the Class 1A-WIO
Certificates, the payments on which consist solely of interest on a notional
principal amount. The most reasonable method is to treat all of the income
derived from such Certificates as constituting OID. This is the position that
will be taken by the REMIC. Among other possibilities, the Service could assert
that this Class of Certificates should instead be taxable under certain Treasury
regulation provisions governing debt instruments issued with contingent
payments.
 
     If actual prepayments on the Mortgage Loans were to differ significantly
from the [     %] SPA, the calculation of OID for certain Classes of Offered
Certificates, such as the [Class                ] Certificates, might produce a
negative amount of OID for certain accrual periods ("Negative OID"). In such
event, Certificateholders of these Classes of Certificates likely would not be
entitled to a deduction for the Negative OID amount, but instead will be
required to carry such amount forward as an offset to OID, if any, accruing in
future periods.
 
     The [Class                ] Certificates will be issued at a premium for
federal income tax purposes. A Holder of such a Certificate may elect to
amortize such premium generally under a constant yield method over the life of
the Certificate, as an offset to interest income. Any such election may affect
the tax treatment of other debt instruments owned by the Holder, however, and
accordingly, Holders should consult their tax advisors regarding the possibility
and consequences of making such an election. See "Certain Federal Income Tax
Consequences -- REMIC Certificates -- Regular Certificates -- Premium" in the
Prospectus.
 
     For further information regarding the federal income tax consequences of
investing in the Certificates, see "Certain Federal Income Tax
Consequences -- REMIC Certificates -- Regular Certificates" in the Prospectus.

<PAGE>   47
 
SPECIAL TAX CONSIDERATIONS APPLICABLE TO THE CLASS R CERTIFICATE
 
     The Class R Certificateholder likely will be required to report an amount
of taxable income (including excess inclusions, which generally may not be
offset with any other losses of the Holder) in earlier accrual periods in
respect of their Class R Certificate significantly in excess of cash
distributions received on such Certificates for such periods. In addition, the
inclusion of taxable income in respect of the ownership of Class R Certificate
during earlier accrual periods and the deferral of corresponding tax losses or
deductions on these Certificates until later accrual periods or until the
ultimate sale or disposition of a Class R Certificate (or possibly even later
pursuant to the application of the "wash sale" rules under Section 1091 of the
Code) may cause the present value of a Class R Certificateholder's resulting tax
liabilities attributable to the ownership of a Class R Certificate to
substantially exceed the sum of any tax benefits and any cash distributions on
the Class R Certificate over its life.
 
     Moreover, as previously discussed with respect to the [Class
               ] Certificates, and in the Prospectus, the rules for accrual of
original issue discount with respect to certain Certificates are subject to
significant complexity and uncertainty. Because original issue discount on
applicable Certificates will be deducted in determining REMIC taxable income,
any changes required by the Service in the application of the OID rules to such
Certificates may significantly affect the timing of the REMIC's original issue
discount deductions and therefore the amount of taxable income allocable to the
Holder of the Class R Certificate.
 
     The REMIC Regulations impose various restrictions on the transfer and
acquisition of residual interests, such as the Class R Certificate, including
prohibitions on the transfer of "non-economic" residual interests to certain
non-United States persons. The Pooling and Servicing Agreement generally
prohibits the transfer of the Class R Certificate to non-United States persons
(as defined therein). Moreover, the REMIC Regulations provide that a transfer to
a United States person of a "noneconomic" residual interest will be disregarded
for all federal income tax purposes, and the purported transferor of the
"noneconomic" residual interest will continue to remain liable for any taxes due
with respect to the income on such residual interest, unless no significant
purpose of the transfer was to impede the assessment or collection of tax. It is
expected that the Class R Certificate will constitute a noneconomic residual
interest at all times. Accordingly, any purported transfer of a Class R
Certificate to a United States person will not be given effect for federal
income tax purposes, and the purported transferor will remain liable for any
taxes due with respect to the income on the Class R Certificate, unless no
significant purpose of such a transfer is to impede the assessment or collection
of tax. See also "Certain Federal Income Tax Consequences -- REMIC
Certificates -- Tax-Related Restrictions on Transfers of Residual Certificates"
in the Prospectus.
 
     The Master Servicing Fees, Subservicing Fees, and Trustee Fees, and other
administrative expenses properly allocable to a REMIC will be allocated for
federal income tax information reporting purposes entirely to the Class R
Certificate. An individual, trust or estate that holds (whether directly or
indirectly through certain pass-through entities) an interest in a Class R
Certificate may be subject to certain limitations on the deductibility of these
fees and expenses in computing such Certificateholder's regular tax liability.
Moreover, such fees or expenses will not be deductible to any extent in
computing such Certificateholder's alternative minimum tax liability. See
"Certain Federal Income Tax Consequences -- Residual Certificates" and
"-- Taxation of the REMIC -- Net Losses of the REMIC" in the Prospectus.
 
     A purchaser of the Class R Certificate is urged to consult its tax advisors
as to the economic, tax and other legal consequences of an investment in the
Class R Certificate.
 
     For further information regarding the federal income tax consequences of
investing in the Class R Certificate, see "Certain Federal Income Tax
Consequences -- Residual Certificates" and "-- Taxation of the REMIC" in the
Prospectus. For further information regarding the federal income tax
consequences of investing in the Certificate, see "Certain Federal Income Tax
Consequences' in the Prospectus.
 
                          STATE, LOCAL AND OTHER TAXES
 
     The foregoing does not address any aspect of state, local, foreign or other
tax consequences to an investor arising from the purchase, ownership or
disposition of a Certificate, and the Depositor makes no representation
                                      S-40
<PAGE>   48
 
in this regard. All investors should consult their tax advisors regarding the
particular federal, state, local, foreign or other tax consequences tot hem from
the purchase, ownership and disposition of the Certificates.
 
                              ERISA CONSIDERATIONS
 
     Title I of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") imposes certain requirements on certain employee benefit plans and
arrangements, and upon collective investment funds and separate accounts in
which such plans or arrangements are invested, and on those persons who are
fiduciaries with respect to such benefit plans. In accordance with ERISA's
general fiduciary standards, before investing in a Class A Certificate a benefit
plan fiduciary should determine whether such an investment is permitted under
the governing benefit plan instruments and is appropriate for the benefit plan
in view of its overall investment policy and the composition and diversification
of its portfolio.
 
     In addition, benefit plans subject to Title I of ERISA and individual
retirement accounts or certain types of Keogh plans not subject to Title I of
ERISA but subject to Section 4975 of the Internal Revenue Code of 1986, as
amended (the "Code") (each a "Plan") are prohibited from engaging in a broad
range of transactions relating to the assets of the Plan when persons having
certain specified relationships to a Plan (called "parties in interest" in ERISA
and "disqualified persons" in the Code) are involved. Such transactions are
treated as "prohibited transactions" under Sections 406 and/or 407 of ERISA, and
excise taxes are imposed upon such persons by Section 4975 of the Code. The
Depositor, the Master Servicer, the Sub-servicers, the Trustee, the Underwriter,
the Certificate Insurer and certain of their affiliates might be considered
"parties in interest" or "disqualified persons" with respect to a Plan. If so,
the acquisition or holding or transfer of Class A Certificates by or on behalf
of such Plan could be considered to give rise to a "prohibited transaction"
within the meaning of ERISA and/or the Code unless an exemption is available. A
Plan fiduciary considering an investment in Class A Certificates should consider
whether such investment will give rise to prohibited transactions under ERISA or
the Code.
 
     The U.S. Department of Labor ("Labor") has issued regulations (29 C.F.R.
Section 2510.3-101) concerning the definition of what constitutes the assets of
a Plan (the "Plan Asset Regulations"), which provide that, as a general rule,
the underlying assets and properties of corporations, partnerships, trusts and
certain other entities in which a Plan makes an "equity" investment (as opposed
to a "debt" investment) will be deemed for purposes of ERISA to be assets of the
investing Plan unless, among other exceptions, the equity participation by Plan
investors in the equity investment is not "significant". Under the Plan Asset
Regulations, equity participation by benefit plan investors is "significant" on
any date if, immediately after the most recent acquisition of the equity
interest, 25% or more of the value of any class of equity interests in the
entity is held by retirement plans, including Plans and plans not subject to
ERISA (such as governmental and church plans). Under the Plan Asset Regulations,
an "equity" investment is an investment in an entity other than an investment
treated as indebtedness under applicable local law and which has no substantial
equity features. The beneficial interest in a trust, the undivided ownership
interest in property and the profit interest in a partnership are deemed to be
equity investments for this purpose.
 
     If an investing Plan's assets were deemed (under the Plan Asset Regulations
or other authority) to include an interest in the Mortgage Loans and any other
assets of the Trust, and not merely an interest in the Class A Certificates, the
assets of the Trust would become subject to the fiduciary standards of ERISA,
and necessary operational Trust transactions involving the Depositor, the Master
Servicer, the Sub-servicers, the Trustee, the Underwriter, the Certificate
Insurer, or any of their affiliates might constitute prohibited transactions,
unless an exemption applies. One such exemption which may be applicable to the
acquisition and holding of the Class A Certificates or to the servicing of the
Mortgage Loans is noted below. See also "ERISA Considerations" in the
Prospectus.
 
     Regardless of whether the Mortgage Loans and any other assets of the Trust
would be considered "plan assets" for purposes of ERISA, the acquisition or
holding of Class A Certificates on behalf of a Plan could still be considered to
give rise to a prohibited transaction if the Trust is or becomes a party in
interest or disqualified person with respect to such Plan, or if a subsequent
transfer of Class A Certificates is made between a Plan and such party in
interest or disqualified person, unless an exemption applies. One such
                                      S-41
<PAGE>   49
 
exemption which may be applicable to such transactions is noted below. See also
"ERISA Considerations" in the Prospectus.
 
     Labor has granted an individual administrative exemption to First Union
Corporation and its affiliates, Prohibited Transaction Exemption ("PTE") 96-22
("Underwriter Exemption"), from certain of the prohibited transaction rules of
ERISA and the Code with respect to the initial purchase, the holding and the
subsequent resale in the secondary market by Plans of pass-through certificates
representing beneficial undivided ownership interests in the assets of a trust
that consist of certain receivables, loans and other obligations that meet the
conditions and requirements of the Underwriter Exemption which may be applicable
to the Class A Certificates if First Union Corporation or any of its affiliates
is either the sole underwriter or the manager or co-manager of the underwriting
syndicate, or a selling or placement agent. On July 21, 1997, PTE 96-22 was
amended and consolidated with other similar exemptions in the form of PTE 97-34.
 
     The Underwriter Exemption provides relief from the restrictions of sections
406(a) and 407 of ERISA and the excise taxes imposed under section 4975(c)(1)(A)
through (D) of the Code, if the general conditions outlined below are satisfied,
in connection with (i) the direct or indirect sale, exchange or transfer of
Class A Certificates in the initial issuance of such certificates between the
Issuer or the Underwriter and a Plan, (ii) the direct or indirect acquisition or
disposition of Class A Certificates by a Plan in the secondary market, and (iii)
the continued holding of Class A Certificates so acquired. However, the
Underwriter Exemption does not provide an exemption from the restrictions of
sections 406(a)(1)(E), 406(a)(2) and 407 of ERISA for the acquisition or holding
of a Class A Certificate on behalf of an "Excluded Plan" by any person who has
discretionary authority or renders investment advice with respect to the assets
of that "Excluded Plan." For purposes of the Class A Certificates, an "Excluded
Plan" is a Plan sponsored by any the Depositor, the Master Servicer, any
Sub-servicer, the Trustee, the Underwriter, the Certificate Insurer, or any
other servicers or any obligor with respect to Mortgage Loans included in the
Trust constituting more than 5% of the aggregate unamortized principal balance
of the assets in the Trust or any affiliate of such parties (the "Restricted
Group").
 
     In addition, the Underwriter Exemption provides relief from the
self-dealing/conflict of interest restrictions of sections 406(b)(1) and (b)(2)
of ERISA and the excise taxes imposed under section 4975(c)(1)(E) of the Code in
connection with the direct or indirect sale, exchange or transfer of Class A
Certificates in the initial issuance of such certificates between the Issuer or
the Underwriter and a Plan, and the continued holding of Class A Certificates so
acquired, if (i) the person who has discretionary authority or renders
investment advice with respect to the investment of Plan assets in the Class A
Certificates (or its affiliate) is an obligor with respect to 5% or less of the
fair market value of the Mortgage Loans contained in the Trust, (ii) solely in
the case of an acquisition of Class A Certificates in connection with the
initial issuance of such certificates, at least 50% of each class of
certificates in which Plans have invested is acquired by persons independent of
the members of the Restricted Group and at least 50% of the aggregate interest
in the Trust is acquired by persons independent of the Restricted Group, (iii)
the Plan is not an Excluded Plan, (iv) the Plan's investment in each class of
certificates does not exceed 25% of the certificates of that class outstanding
at the time of the Plan's acquisition and after the Plan's acquisition of Class
A Certificates, no more than 25% of the assets over which the fiduciary has
investment authority are invested in securities of a trust containing assets
which are sold or serviced by the same entity, and (v) the general conditions
outlined below are met.
 
     The Underwriter Exemption also provides relief from the
self-dealing/conflict of interest restrictions of sections 406(b)(1) and (b)(2)
of ERISA and the excise taxes imposed under section 4975(c)(1)(E) of the Code in
connection with the direct or indirect acquisition or disposition of Class A
Certificates by a Plan in the secondary market, and the continued holding of
Class A Certificates so acquired, if the requirements specified in (i), (iii),
(iv) and (v) above are met.
 
     Finally, the Underwriter Exemption also provides an exemption from the
prohibited transaction restrictions for transactions in connection with the
servicing, management and operation of the Trust if such transactions are
carried out in accordance with the terms of a binding pooling and servicing
arrangement provided to, or described in all material respects in a prospectus
or private placement memorandum provided
 
                                      S-42
<PAGE>   50
 
to, investing Plans and the general conditions outlined below are satisfied. It
is expected that this exemption will be available, provided that the general
conditions outlined below are satisfied.
 
     The general conditions which must be satisfied for the Underwriter
Exemption to apply are:
 
          (i) The acquisition of the Class A Certificates by a Plan is on terms
     (including the price for the Class A Certificates) that are at least as
     favorable to the Plan as they would be in an arm's length transaction with
     an unrelated party.
 
          (ii) The rights and interests evidenced by Class A Certificates
     acquired by the Plan are not subordinated to the rights and interests
     evidenced by any other Certificates of the Trust.
 
          (iii) The Class A Certificates acquired by the Plan have received a
     rating at the time of such acquisition that is in one of the three highest
     generic rating categories from any of Moody's Investor Service, Inc.,
     ("Moody's") Duff & Phelps Credit Rating Co., Standard & Poor's Structured
     Rating Services, a division of The McGraw-Hill Companies, Inc. ("Standard
     and Poor's"), or Fitch Investors Service, L.P. ("Authorized Rating
     Agencies").
 
          (iv) The investment pool consists only of assets of the type
     enumerated in the Underwriter Exemption, and which have been included in
     other investment pools; certificates evidencing interests in such other
     investment pools have been rated in one of the three highest generic rating
     categories by an Authorized Rating Agency for at least one year prior to a
     Plan's acquisition of certificates; and certificates evidencing interests
     in such other investment pools have been purchased by investors other than
     Plans for at least one year prior to a plan's acquisition of the Class A
     Certificates.
 
          (v) The sum of all payments made to and retained by the Underwriter in
     connection with the distribution or placement of the Class A Certificates
     represents not more than reasonable compensation for underwriting or
     placing the Class A Certificates. The sum of all payments made to and
     retained by the Depositor pursuant to the sale of the Mortgage Loans to the
     Trust represents not more than the fair market value of such Mortgage
     Loans. The sum of all payments made to and retained by the Master Servicer,
     the Sub-servicers or any other servicer represents not more than reasonable
     compensation for such services under the Agreement and reimbursement of the
     servicers' reasonable expenses in connection therewith.
 
          (vi) The Trustee is not an affiliate of any member of the Restricted
     Group.
 
          (vii) The Plan investing in the Class A Certificates is an "accredited
     investor" as defined in Rule 501(a)(1) of Regulation D under the Securities
     Act of 1933. Any Plan purchasing Class A Certificates will be deemed to
     have represented, by virtue of such purchase, that it is an accredited
     investor.
 
     Because the Class A Certificates are not subordinated to any other class of
Certificates, the second general condition set forth above is satisfied with
respect to the Class A Certificates. It is a condition of issuance of the Class
A Certificates that they be rated not lower than "AAA" and ["Aaa" by Standard &
Poor's Structured Rating Group and Moody's Investor Service, Inc.,
respectively]; thus, the third general condition set forth above is satisfied
with respect to the Class A Certificates as of the Closing Date. The Trustee
will not be an affiliate of any member of the Restricted Group on the Closing
Date; thus, the sixth general condition set forth above is satisfied with
respect to the Class A Certificates as of the Closing Date. A fiduciary of a
Plan contemplating the purchase of Class A Certificates in the secondary market
must make its own determination that, at the time of purchase, the Class A
Certificates continue to satisfy the third and sixth general conditions set
forth above. A fiduciary of a Plan contemplating the purchase of Class A
Certificates must make its own determination that the first, fifth and seventh
conditions set forth above will be satisfied with respect to the Class A
Certificates as of the date of such purchase.
 
     Because of the complexity of the prohibited transaction rules and the
relevant exemptions as well as the penalties imposed on prohibited transactions,
before purchasing a Class A Certificate in reliance on an exemption, including
the Underwriter Exemption, a fiduciary of a Plan should confirm that all
applicable requirements would be satisfied. Any Plan fiduciary considering the
purchase of a Class A Certificate should
                                      S-43
<PAGE>   51
 
consult with its counsel with respect to the potential applicability of ERISA
and the Code to such investment. Moreover, each Plan fiduciary should determine
whether, under the general fiduciary standards of investment prudence and
diversification, an investment in the Class A 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. See "ERISA Considerations" in
the Prospectus.
 
     Any Plan purchasing Class A Certificates shall be deemed to have
represented, by virtue of such purchase, that such an investment is (i)
permitted under the governing benefit plan instruments, (ii) appropriate for the
benefit plan in view of its overall investment policy and the composition and
diversification of its portfolio, (iii) consistent with the requirements of
ERISA and the Code, and (iv) to the extent necessary, eligible for exemption
from the applicable prohibited transaction restrictions of ERISA and the Code.
 
                                LEGAL INVESTMENT
 
     The Class A Certificates will constitute "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984 ("SMMEA") so
long as they are rated in one of the two highest rating categories by at least
one nationally recognized statistical rating organization. As such, the Class A
Certificates are legal investments for certain entities to the extent provided
in the SMMEA. The Depositor makes no representation as to the ability of
particular investors to purchase the Class A Certificates under applicable legal
investment or other restrictions. All institutions whose investment activities
are subject to legal investment laws and regulations, regulatory capital
requirements or review by regulatory authorities should consult with their own
legal advisors in determining whether and to what extent the Class A
Certificates constitute legal investments for them or are subject to investment,
capital or other restrictions. It should also be noted that certain states
recently have enacted, or have proposed enacting, legislation limiting to
varying extents the ability of certain entities (in particular insurance
companies) to invest in mortgage related securities. Investors should consult
with their own legal advisors in determining whether and to what extent the
Class A Certificates constitute legal investments for such investors. See "Legal
Investment" in the Prospectus.
 
                                USE OF PROCEEDS
 
     Substantially all of the net proceeds to be received from the sale of the
Class A Certificates will be applied by the Depositor to the purchase price of
the Mortgage Loans and expenses connected with pooling the Mortgage Loans and
issuing the Certificates.
 
                                  UNDERWRITING
 
     First Union Capital Markets Corp., the [sole] underwriter, has agreed, on
the terms and conditions of the Underwriting Agreement and a Terms Agreement
(together, the "Underwriting Agreement") relating to the Class A Certificates,
to purchase the entire principal amount of the Class A Certificates offered
hereby.
 
     In the Underwriting Agreement, the Underwriter has agreed, subject to the
terms and conditions set forth therein, to purchase all the Class A Certificates
offered hereby if any Class A Certificates are purchased.
 
     The distribution of the Class A Certificates by the Underwriter may be
effected from time to time in one or more negotiated transactions, or otherwise,
at varying prices to be determined, in each case, at the time of sale. This
Prospectus Supplement and the Prospectus may be used by the First Union Capital
Markets Corp. or any of its affiliates in connection with offers and sales
related to market-making transactions in the Class A Certificates. The
Underwriter may act as principal or agent in such transactions.
 
     The Underwriter may effect such transactions by selling the Class A
Certificates to or through dealers, and such dealers may receive compensation in
the form of underwriting discounts, concessions or commissions from the
Underwriter. In connection with the sale of the Class A Certificates, the
Underwriter may be deemed to have received compensation from the Depositor in
the form of underwriting compensation. The Under-
                                      S-44
<PAGE>   52
 
writer and any dealers that participate with the Underwriter in the distribution
of the Class A Certificates may be deemed to be underwriters and any commissions
received by them and any profit on the resale of the Class A Certificates
positioned by them may be deemed to be underwriting discounts and commissions
under the Securities Act of 1933.
 
     The Underwriting Agreement provides that the Depositor will indemnify the
Underwriter against certain liabilities, including liabilities under the
Securities Act of 1933, or contribute to payments the Underwriter may be
required to make in respect thereof.
 
     All of the Mortgage Loans evidenced by the Certificates will have been
acquired by the Depositor in a privately negotiated transaction with the Seller.
 
                                    EXPERTS
 
     The consolidated balance sheets [and other selected financial information]
of [the Certificate Insurer] appearing in Appendix A to this Prospectus
Supplement, have been included herein in reliance upon the report of
               , independent certified public accountants, included in Appendix
A to this Prospectus Supplement, and upon the authority of said firm as experts
in accounting and auditing.
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the Certificates will be passed upon
by Moore & Van Allen, PLLC, Charlotte, North Carolina.
 
                               CERTIFICATE RATING
 
     It is a condition to the issuance of the Certificates that the Class A
Certificates be rated AAA by Standard & Poor's and Aaa by Moody's. Standard &
Poor's assigns the additional symbol of "r" to highlight classes of securities
that Standard & Poor's believes may experience high volatility or high
variability in expected returns due to non-credit risks; however, the absence of
an "r" symbol should not be taken as an indication that a class will exhibit no
volatility or variability in total return.
 
     The ratings of Standard & Poor's and Moody's do not represent any
assessment of the ability of the Master Servicer to purchase any Converting
Mortgage Loan. 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
rating agency. The ratings assigned to the Class A Certificates address the
likelihood of the receipt of distributions due on the Class A Certificates
according to their terms. The ratings take into consideration, among other
things, the credit quality of the Mortgage Loans, the structural and legal
aspects associated with the Class A Certificates, and the claims-paying ability
of the Certificate Insurer. An adverse change in any of such factors or in other
factors may be a basis for the downward revision or withdrawal of the rating of
any Class of Class A Certificates affected by such change. The ratings assigned
to the Class A Certificates do not represent any assessment of the likelihood
that principal prepayments might differ from those originally anticipated. The
rating does not address the possibility that the Holders of the Class A
Certificates might suffer a lower than anticipated yield. There can be no
assurance as to whether any other rating agency will rate the Class A
Certificates, or if it does, what rating it will assign to the Class A
Certificates.

TITLE OF THE SECURITIES
 
The Home Equity Loan Asset-Backed Certificates Series 1999-     , Class A
Certificates (the "Class A Certificates" or the "Certificates"), are being
offered pursuant to the FURST Home Equity Loan Trust Series 1999-     (the
"Trust" or "Trust Fund"). The Class A Certificates (the "Offered Certificates")
represent an interest in the assets of the Trust. Each class of Certificates
within the Class A, Class B and Class R Certificates is referred to herein as a
"Class."
 
The Class B and Class R Certificates [which are not offered in this Prospectus
Supplement] are subordinated to the Class A Certificates.
 
Each registered holder of a Certificate (a "Certificateholder" or a "Holder")
will be entitled to monthly payments of interest and principle. See "Description
of the Certificates" in this Prospectus Supplement and in the Prospectus.
 
DEPOSITOR
 
First Union Residential Securitization Transactions, Inc. ("FURST"), a North
Carolina corporation, a wholly-owned, limited purpose subsidiary of the Seller
and an affiliate of First Union Capital Markets Corp., will sell the Mortgage
Loans to the Trust Fund in exchange for the Certificates. The Mortgage Loans
will be acquired by the Depositor from the Seller.
 
SELLER
 
First Union National Bank, a national banking association, a wholly-owned
subsidiary of First Union Corporation and an affiliate of First Union Capital
Markets Corp., will originate or acquire the Mortgage Loans and sell them to the
Depositor.
 
THE TRUST AND THE TRUSTEE
The Trust will be formed pursuant to a Pooling and Servicing Agreement dated as
of                , 1999 (the "Agreement") among FURST as the Depositor (the
"Depositor"), FUNB as seller (the "Seller") and master servicer (the "Master
Servicer") and [               ] as the trustee (the "Trustee") and
[               ] as the document custodian (the "Document Custodian").
 
THE ASSETS OF THE TRUST
 
The property of the Trust will include a pool of closed-end fixed or variable
rate home equity loans (the "Mortgage Loans"), secured by first and second deeds
of trust, security deeds or mortgages on residential properties that are
primarily one- to four-family properties (the "Mortgaged Properties").
 
As of                , 199 , which is the "Cut-Off Date," the aggregate size of
the pool of Mortgage Loans (the "Pool Balance") was $          . The Pool
Balance of Mortgage Loans is referred to as the "Cut-Off Date Pool Balance."
 
The per annum interest rate (the "Mortgage Rate") for certain of the Mortgage
Loans is adjusted monthly and the Mortgage Rate for the remainder of the
Mortgage Loans is adjusted every six months. The adjustment date is referred to
as the "Interest Adjustment Date." Subject to its maximum Mortgage Rate, the
Mortgage Rate borne by a Mortgage Loan may be calculated as described under the
"The Mortgage Loan Pool" section of this Prospectus Supplement.
 
ALLOCATIONS OF TRUST ASSETS
 
Distributions of interest and principal to each Holder of a Certificate will be
made on the   th
 
                                       S-1
<PAGE>   64
 
day of each month (or if such   th day is not a business day, then on the next
succeeding business day) (each, a "Distribution Date"), commencing in
               1999.
 
As more fully described in the "Description of the Certificates -- Distributions
to the Certificateholders" section of this Prospectus Supplement, distributions
will be made:
 
- - to the holders of each Class of Certificates (up to the amount to which they
  are entitled under the terms of the Agreement), and
 
- - any remaining balance to Holders of the Class R Certificates (the "Class R
  Certificateholders").
 
The foregoing schedule of distributions is subject to the availability of funds
in the Collection Account (as such term is defined below under "The Mortgage
Pool").
 
The final payment of principal and interest on the Certificates will be made no
later than             ,                , or, if that date is not a business
day, the next business day, called the "Legal Final Maturity" or the "Series
1999-   Termination Date."
 
CREDIT ENHANCEMENT
 
The Certificates will have a Credit Enhancement that provides additional Payment
protection to investors in each Class of Certificates that has Credit
Enhancement.
 
For a discussion on the type of Credit Enhancement available to the
Certificateholders, see "Description of the Certificates -- Certificate
Insurance Policy" in this Prospectus Supplement.
 
ADVANCES
 
The Master Servicer is obligated to make advances of cash, which will be part of
the Available Distribution Amount, in an amount equal to the delinquent Monthly
Payments due on the immediately preceding Due Date (the "Advances").
 
The Master Servicer is not obligated to make Advances if it determines that such
Advances are not recoverable from future payments or collections on the related
Mortgage Loans. Such Advances, however, will be reimbursed to the Master
Servicer and are not intended to guarantee or insure against losses. See
"Description of the Certificates -- Advances" herein.
 
OPTIONAL TERMINATION
 
The Master Servicer has the option to repurchase from the Trust Fund all
Mortgage Loans remaining outstanding on any Distribution Date when the aggregate
unpaid Principal Balance of such Mortgage Loans is less than 10% of the
aggregate unpaid principal balance of the Mortgage Loans on the Cut-Off Date.
 
If the Master Servicer does not repurchase all the Mortgage Loans, the
Certificate Insurer has the same option.
 
For more information on this option, see "Description of the
Certificates -- Optional Termination" herein.
 
PREPAYMENT AND YIELD CONSIDERATIONS
 
The actual rate of prepayment of principal on the Mortgage Loans cannot be
predicted. The performance of the Class A Certificates may vary materially and
adversely from the investment expectations of investors due to prepayments on
the Mortgage Loans being higher or lower than anticipated by investors. For more
information on the effects that prepayments will have on the yield and
performance of the Certificates, see "Prepayment and Yield Considerations" in
this Prospectus Supplement.
 
DENOMINATIONS
 
Beneficial interest in the Certificates will be offered in minimum denominations
of $1,000 and integral multiples of that amount.
 
REGISTRATION, CLEARANCE AND SETTLEMENT
 
Your Certificates will be registered in the name of Cede & Co. ("Cede"), as the
nominee of the Depository Trust Company ("DTC"). You will not receive a
definitive certificate representing your interest, except in limited
circumstances described in the accompanying Prospectus when Certificates in
fully registered, certificated form are issued. See "Description of the
Certificates -- Registration of the Class A Certificates" in this Prospectus
Supplement.
 
You may elect to hold your Certificates through DTC, in the United States, or
Cedel Bank, societe anonyme ("Cedel") or the Euroclear System
 
                                       S-2
<PAGE>   65
 
("Euroclear"), in Europe. Transfers within DTC, Cedel or Euroclear, as the case
may be, will be made in accordance with the usual rules and operating procedures
of those systems. Cross-market transfers between persons holding directly or
indirectly through DTC and counterparties holding directly or indirectly through
Cedel or Euroclear will be made in DTC through the relevant depositories of
Cedel or Euroclear. See "Description of the Certificates -- Registration of the
Certificates" in this Prospectus Supplement.
 
We expect that the Certificates will be delivered in book-entry form through the
facilities of DTC, Cedel and Euroclear on or about                          ,
1999.
 
RECORD DATE
 
The Record Date will be the last day [of the month] preceding a Distribution
Date.
 
THE MASTER SERVICER
 
The Master Servicer is responsible for servicing, managing and making
collections on the Mortgage Loans. The Master Servicer will also make the
appropriate allocations to the Collection Account.
 
The Master Servicer will be paid a "Servicing Fee Rate" as compensation for its
services to the Trust.
 
For a discussion regarding the Master Servicer's obligations and compensation,
see "Description of the Certificates -- Distributions on the Certificates" in
this Prospectus Supplement.
 
TAX STATUS
 
The Trust will make election to be treated as a "real estate mortgage investment
conduit" ("REMIC") under the provisions of the Internal Revenue Code of 1986, as
amended (the "Code"). The election to be treated as a REMIC will have federal
income tax consequences for the Certificateholders. See "Certain Federal Income
Tax Consequences" in the Prospectus
 
ERISA CONSIDERATIONS
 
If you are a fiduciary of an employee benefit plan or other retirement plan or
arrangement that is subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), you must consult with legal advisors to determine if
purchasing or holding of Certificates is a prohibited transaction or otherwise
prohibited under ERISA.

Certain classes of Certificates may only be transferred if the Trustee and the
Depositor receive a letter of representations or an opinion of counsel that such
transfer will not violate ERISA or the Code. In addition, the letter of
representation or opinion of counsel must also state that the Trustee, Depositor
or the Master Servicer will not be subject to additional obligations. See "ERISA
Considerations" in the Prospectus.
 
LEGAL INVESTMENT CONSIDERATIONS
 
The Class A Certificates must be rated in one of the two highest rating
categories by at least one nationally recognized statistical rating agency in
order to constitute "mortgage related securities" under the Secondary Mortgage
Market Enhancement Act of 1984. Only "mortgage related securities" will be
"legal investments" for certain types of institutional investors to the extent
provided in such Act. See "Legal Investment Considerations" in the Prospectus.
 
USE OF PROCEEDS
 
The net proceeds from the sale of the Class A Certificates will be applied by
the Depositor to the purchase price of the Mortgage Loans and to pay expenses
connected with pooling the Mortgage Loans and issuing the Certificates. See "Use
of Proceeds" herein.
 
CERTIFICATE RATING
 
Any certificate offered by this Prospectus and the accompanying Prospectus
Supplement will be rated in one of the four highest rating categories by at
least one nationally recognized rating organization. Any nationally recognized
rating organization selected by the Seller to rate any Series is a "Rating
Agency."
 
A rating is not a recommendation to buy, sell or hold securities and may be
revised or withdrawn at any time by the assigning Rating Agency. Each rating
should be evaluated independently of any other rating. See "Certificate Rating"
in this Prospectus Supplement.

<PAGE>   66
 
                                  RISK FACTORS
 
     You should consider the following risk factors in deciding whether to
purchase the Certificates.
 
PREPAYMENTS; DUE-ON-SALE PROVISIONS
 
     The rate of distributions of principal and the yield to maturity on your
Certificates will be directly related to the rate of payments of principal on
the Mortgage Loans, and the amount and timing of mortgagor defaults resulting in
realized losses. Mortgagors are permitted to prepay the Mortgage Loans, in whole
or in part, at any time without penalty. In addition, a substantial portion of
the Mortgage Loans contain due-on-sale provisions which, to the extent enforced
by the Master Servicer, will result in prepayment of such Mortgage Loan. The
rate of principal payments on the Mortgage Loans will be affected by, among
other things:
 
     - the amortization schedules of the Mortgage Loans;
 
     - the rate of principal prepayments (including partial payments and those
       resulting from refinancing) thereon by mortgagors;
 
     - liquidations of defaulted Mortgage Loans;
 
     - repurchases of Mortgage Loans by the Seller as a result of defective
       documentation or breaches of representations and warranties, or optional
       purchase by the Seller of defaulted Mortgage Loans; and
 
     - the optional purchase by the Seller of all of the Mortgage Loans in
       connection with the termination of the Trust Fund.
 
     See "Prepayment and Yield Considerations" herein, and "The Pooling and
Servicing Agreement -- Assignment of Mortgage Assets" in the Prospectus.
 
     The rate of payments (including prepayments relating to the mortgage loans,
the "Prepayments") on pools of mortgage loans is influenced by a variety of
economic, geographic, social and other factors, but depends greatly on the level
of mortgage interest rates:
 
     - If prevailing rates for similar mortgage loans fall below the interest
       rates on the Mortgage Loans, the rate of prepayment would generally be
       expected to increase.
 
     - Conversely, if interest rates on similar mortgage loans rise above the
       interest rates on the Mortgage Loans, the rate of prepayment would
       generally be expected to decrease.
 
     The rate of prepayment on the Mortgage Loans may also be influenced by
programs offered by mortgage originators (including FUNB), on a general or
targeted basis, to encourage refinancing.
 
     If you are purchasing Offered Certificates at a discount, particularly the
Class                Certificates, you should consider the risk that if
principal payments on the Mortgage Loans or in the case of the Class
               Certificates on the Discount Mortgage Loans occur at a rate
slower than you expected, your yield may be lower than you expected.
 
     If you are purchasing Offered Certificates at a premium, or are purchasing
the Class                Certificates which have no Principal Balance, you
should consider the risk that if principal payments on the Mortgage Loans or in
the case of the Class                Certificates on the Premium Mortgage Loans
(particularly those loans with higher interest rates) occur at a rate faster
than you expected, your yield may be lower than you expected. IF YOU ARE
PURCHASING CLASS                CERTIFICATES, YOU SHOULD CONSIDER THE RISK THAN
A RAPID RATE OF PRINCIPAL PAYMENTS ON THE PREMIUM MORTGAGE LOANS COULD RESULT IN
YOUR FAILURE TO RECOVER YOUR INITIAL INVESTMENT.
 
LIMITED LIQUIDITY
 
     There is currently no market for the Offered Certificates. While the
Underwriters currently intend to make a market in the Offered Certificates, they
are under no obligation to do so. There can be no assurance
 
                                       S-4
<PAGE>   67
 
that a secondary market will develop or, if a secondary market does develop,
that it will provide you with liquidity of investment or that it will continue
for the lives of the Offered Certificates. The Offered Certificates will not be
listed on any securities exchange.
 
     Issuance of the Offered Certificates in book-entry form may reduce the
liquidity of such Certificates in the secondary trading market since investors
may be unwilling to purchase Offered Certificates for which they cannot obtain
physical certificates. See "Description of the Certificates -- Book-Entry
Registration" herein.
 
RISKS ASSOCIATED WITH MORTGAGE LOANS
 
     Adverse economic conditions (which may or may not affect real property
values) may affect the timely payment by borrowers of payments of principal and
interest when due on the Mortgage Loans and, accordingly, the actual rates of
delinquencies, foreclosures and losses with respect to the Mortgage Loans.
Further, application of federal and state bankruptcy and debtor relief laws
would affect the interests of the Certificateholders in the Mortgage Loans if
such laws result in certain Mortgage Loans being uncollectible. See "Certain
Legal Aspects of the Mortgage Loans -- Anti-Deficiency Legislation; Bankruptcy
and Consumer Protection Legislation" herein.
 
     Even assuming that the Mortgaged Properties provide adequate security for
the Mortgage Loans, delays could be encountered in connection with the
liquidation of defaulted Mortgage Loans, with corresponding delays in the
receipt of related proceeds by the Certificateholders.
 
     Further, the Master Servicer will be entitled to deduct from Liquidation
Proceeds all expenses reasonably incurred in attempting to recover amounts due
on Liquidated Mortgage Loans and not yet repaid, including legal fees and costs
of legal action, real estate taxes, and maintenance and preservation expenses,
thereby reducing collections available to the Certificateholders.
 
     In the event that any Mortgaged Properties fail to provide adequate
security for the related Mortgage Loans and the protection provided by the
subordination feature is insufficient, Certificateholders could experience a
loss on their investment. See "Certain Legal Aspects of the Mortgage
Loans -- Foreclosure" and "-- Rights of Redemption" herein.
 
     Under federal and state environmental legislation and applicable case law,
it is unclear whether liability for costs of eliminating environmental hazards
in respect of real property may be imposed on a secured lender (such as the
Trust Fund) acquiring title to such real property. Such costs could be
substantial. See "Certain Legal Aspects of the Mortgage Loans -- Environmental
Legislation" herein.
 
GEOGRAPHIC CONCENTRATION/LOCAL REAL ESTATE MARKETS
 
     Approximately      % of all Mortgage Loans (by Cut-Off Date Principal
Balances) are secured by Mortgaged Properties located in the State of
               . In addition, approximately      %,      %, and      % of the
Mortgage Loans are located in                ,                , and
               , respectively. See "Certain Legal Aspects of the Mortgage Loans"
and "The Mortgage Loan Pool" herein.
 
     An overall decline in the residential real estate markets in the states in
which the Mortgaged Properties are located could adversely affect the values of
the Mortgaged Properties such that the outstanding Loan Balances equal or exceed
the value of the Mortgaged Properties. Such declines could reduce the interest
of the holder of a mortgage on the Mortgaged Property. Residential real estate
markets in many states have softened in recent years. There is no reliable
information available to the Seller with respect to the rate at which real
estate values have declined in such states. The Seller can neither quantify the
impact of such declines in property values nor predict how long such declines
may continue or when such declines will end. During a period of such declines,
the rates of delinquencies, foreclosures and losses on the Mortgage Loans would
be expected to be higher than those experienced in the mortgage lending industry
in general.
 
     A rise in interest rates over a period of time and the general condition of
the Mortgaged Property as well as other factors may have the effect of reducing
the value of the Mortgaged Property from the appraised value at the time the
Mortgage Loan was originated. If there is a reduction in value of the Mortgaged
Property, the
 
                                       S-5
<PAGE>   68
 
ratio of the amount of the Mortgage Loan to the value of the Mortgaged Property
may increase over what it was at the time the Mortgage Loan was originated. Such
an increase may reduce the likelihood of liquidation or other proceeds being
sufficient to satisfy the Mortgage Loan after satisfaction of any senior liens.
 
RISKS OF HOLDING SUBORDINATE CERTIFICATES
 
     The rights of the Holders of each Class of Subordinate Certificates to
receive distributions will be subordinated to such rights of the Holders of the
Class A Certificates, and the Class M Certificates, and the lower-numbered
Classes of Class B Certificates, if any, with respect to Class B Certificates.
In addition, Realized Losses, other than Excess Losses, will be allocated to the
Subordinate Certificates in the reverse order in which they are entitled to
distributions of principal before being allocated to the Class A Certificates.
Accordingly, if you are purchasing Subordinate Certificates, you will be more
likely to experience losses as a result of the occurrence of losses or interest
shortfalls on the Mortgage Loans.
 
     Under certain circumstances principal otherwise payable to the Subordinate
Certificates will be paid to the Class A Certificates (other than the Class
               Certificates) as described under "Description of the
Certificates -- Cross-Collateralization" herein. In addition, the Class
               Deferred Amount is payable from amounts otherwise distributable
as principal on the Subordinate Certificates.
 
LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO DEPOSITOR, SELLER, MASTER SERVICER,
TRUST ADMINISTRATOR, OR TRUSTEE
 
     The Certificates do not represent an interest in or obligation of the
Depositor, the Seller, the Master Servicer, the Trust Administrator, the Trustee
or any of their affiliates, except for the limited obligations of the Depositor
and the Seller with respect to certain breaches of their representations and
warranties and of the Master Servicer with respect to its servicing obligations.
 
     Neither the Certificates nor the Mortgage Loans will be guaranteed by or
insured by any governmental agency or instrumentality, the Depositor, the
Seller, the Master Servicer, the Trust Administrator, 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 Depositor, the Seller, the Master
Servicer, the Trustee, the Trust Administrator or any of their affiliates.
 
BOOK-ENTRY SYSTEM
 
     Since transactions in the Class A Certificates (other than the Residual
Certificates) and the Senior Subordinate Certificates (collectively, the
"Book-Entry Certificates") generally can be effected only through The Depository
Trust Company ("DTC"), participating organizations, indirect participants and
certain banks, your ability as a Certificateholder to pledge a Book-Entry
Certificate to persons or entities that do not participate in the DTC system, or
otherwise to take actions with respect to such Certificates, may be limited due
to a lack of a physical certificate representing the Book-Entry Certificates.
 
     In addition, as a Certificateholder, you may experience some delay in the
receipt of distribution of interest and principal on the Book-Entry
Certificates, since such distributions will be forwarded by the Trustee (or its
duly appointed paying agent, if any) to DTC, and DTC will credit such
distributions to the accounts of DTC Participants (as defined herein) which will
thereafter credit them to the accounts of Certificateholders either directly or
indirectly through indirect participants.
 
     Also, issuance of the 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 "Description of the
Certificates -- Book-Entry Registration" herein.
 
CERTIFICATE RATINGS
 
     The rating of the Offered Certificates will depend primarily on an
assessment by the Rating Agencies of the underlying Mortgage Loans and the
amount of subordination.
                                       S-6
<PAGE>   69
 
     The rating by the Rating Agencies of the Offered Certificates is not a
recommendation to purchase, hold or sell the Offered Certificates, in as much as
such rating does not comment as to the market price or suitability for a
particular investor. There is no assurance that the ratings will remain for any
given period of time or that the ratings will not be reduced, suspended or
withdrawn by the Rating Agencies.
 
RISK OF YEAR 2000
 
     FUNB and the Trustee utilize a significant number of computer software
programs and operating systems and are highly dependent on computer systems
operated by third parties which include, but are not limited to, their
suppliers, customers, brokers and agents and the telephone, electric and utility
companies. To the extent that any computer system relied upon by FUNB and the
Trustee or any third party, has software applications and contains source codes
that are unable to appropriately interpret the upcoming calendar year 2000, some
level of modification or replacement of such applications or hardware may be
necessary.
 
     The year 2000 issue is the result of prior computer programs being written
using two digits, rather than four digits, to define the applicable year. Any of
FUNB's or the Trustee's computer programs that have time-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. Any such
occurrence could result in a major computer system failure or miscalculations.
Several federal regulatory agencies, including the Securities and Exchange
Commission, require the entities that they regulate to take steps to address
problems which may arise in relation to the year 2000.
 
     FUNB and the Trustee currently are assessing the impact of modifications or
replacements required to adjust for the year 2000. FUNB and the Trustee are
utilizing both internal and external resources to identify, correct or
reprogram, and test their systems for year 2000 compliance. It is anticipated
that all reprogramming efforts and necessary testing will be completed prior to
the year 2000. FUNB and the Trustee have initiated formal communications with
those third parties on whom they will rely to determine the extent to which FUNB
and the Trustee are vulnerable to the failure of these third parties to
remediate their own year 2000 issue. The total year 2000 project cost and
estimates for FUNB and the Trustee include the estimated costs and time
associated with the impact of a third party's year 2000 issue, and are based on
presently available information. However, there can be no assurance that the
systems of third parties on which the systems of FUNB and the Trustee rely will
be converted in a timely fashion, or that a failure to convert by a third party,
or a conversion that is incompatible with the systems of FUNB and the Trustee
would not have an adverse effect on the business, financial condition or results
of operations of FUNB and the Trustee.
 
     The costs allocated to the year 2000 project are significant. The costs of
the project and the dates on which FUNB and the Trustee plan to complete their
year 2000 modifications are based on their best estimates, which were derived
utilizing numerous assumptions of future events including the continued
availability of certain resources, third party modification plans and other
factors. However, there can be no assurance that these estimates will be
achieved and actual results could differ materially from such estimates.
Specific factors that might cause such material differences include, but are not
limited to: (i) the availability and cost of personnel trained in this area,
(ii) the ability to locate and correct all relevant computer codes and (iii)
similar uncertainties.
 
     No assurance can be given that any or all of the systems discussed above,
including the systems of FUNB and the Trustee, are or will be year 2000
compliant or that the costs required to address year 2000 issues will not
adversely affect the business, financial condition or results of operations of
the respective party or the performance of their obligations under the Pooling
and Servicing Agreement. As a result of this potential affect on performance
under the Pooling and Servicing Agreement, the timely receipt of payment by the
Certificateholders may also be adversely affected.
 
     DTC has informed its participants and other members of the financial
community (the "Industry") that it believes that it has developed and is
implementing a program so that its computer hardware and software systems, as
the same relate to the timely payment of distributions (including principal and
income payments) to securityholders, book-entry deliveries, and settlement of
trades within DTC, will continue to function appropriately. This program
includes a technical assessment and remediation plan, each of which, according
to
 
                                       S-7
<PAGE>   70
 
DTC, is complete. Additionally, DTC's plan includes a testing phase which is
expected to be completed within appropriate time frames.
 
     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors on whom DTC relies for information or the provision
of services, including telecommunication and electrical utility service
providers, among others. DTC has informed the Industry that it is contacting
(and will continue to contact) third party vendors from whom DTC acquires
services to: (1) impress upon them the importance of such services being year
2000 compliant; and (2) determine the extent of their efforts for year 2000
remediation (and, as appropriate, testing) of their services. In addition, DTC
is in the process of developing such contingency plans as it deems appropriate.
 
     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for information purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.
 
OTHER LEGAL CONSIDERATIONS
 
     Certain states have imposed statutory prohibitions which limit the remedies
of either a beneficiary under a deed of trust or security deed or a mortgagee
under a mortgage. In some states, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure or sale under a deed of trust, security deed or mortgage. A
deficiency judgment would be a personal judgment against the former borrower
equal in most cases to the difference between the net amount received upon the
public sale of the real property and the amount due to the lender.
 
     Other statutes require the beneficiary or mortgagee to exhaust the security
afforded under a deed of trust, security deed or mortgage by foreclosure in an
attempt to satisfy the full debt before bringing a personal action against the
borrower.
 
     Finally, other statutory provisions limit any deficiency judgment against
the former borrower following a judicial sale to the excess of the outstanding
debt over the fair market value of the property at the time of the public sale.
The purpose of these statutes is generally to prevent a beneficiary or a
mortgagee from obtaining a large deficiency judgment against the former borrower
as a result of low or no bids at the judicial sale.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of the Seller. In addition,
other state laws, public policy and general principles of equity relating to the
protection of consumers, unfair and deceptive practices and debt collection
practices may apply to the origination, servicing and collection of the Mortgage
Loans.
 
     The Seller will be required to repurchase any Mortgage Loans which, at the
time of origination did not comply with applicable federal and state laws and
regulations. Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and
principles may limit the ability of the Trust Fund to collect all or part of the
principal of or interest on the Mortgage Loans, may entitle the borrower to a
refund of amounts previously paid and, in addition, could subject the Trust Fund
to damages and administrative enforcement. See "Certain Legal Aspects of
Mortgage Loans" herein.
 
     The Mortgage Loans are also subject to federal laws, including:
 
     - the federal Truth in Lending Act and Regulation Z promulgated thereunder,
       which require certain disclosures to the borrowers regarding the terms of
       the Mortgage Loans;
 
     - the Equal Credit Opportunity Act and Regulation B promulgated thereunder,
       which prohibit discrimination on the basis of age, race, color, sex,
       religion, marital status, national origin, receipt of public assistance
       or the exercise of any right under the Consumer Credit Protection Act, in
       the extension of credit;
 
     - the Fair Credit Reporting Act, which regulates the use and reporting of
       information related to the borrower's credit experience;
 
                                       S-8
<PAGE>   71
 
     - the Americans with Disabilities Act, which, among other things, prohibits
       discrimination on the basis of disability in the full and equal enjoyment
       of the goods, services, facilities, privileges, advantages or
       accommodations of any place of public accommodation; and
 
     - the Real Estate Settlement Procedures Act and the Fair Credit Billing
       Act.
 
     The federal Soldiers' and Sailors' Civil Relief Act of 1940 may affect the
ability of the Master Servicer to collect full amounts of interest on certain
Mortgage Loans and could interfere with the ability of the Master Servicer to
foreclose on certain properties. See "Certain Legal Aspects of the Mortgage
Loans -- Soldiers' and Sailors' Civil Relief Act of 1940" herein.
 
RISK OF EARLY DEFAULTS
 
     The majority of the Mortgage Loans were originated within        months
prior to the Cut-Off Date. The weighted average stated remaining term to
maturity of the Mortgage Loans as of the Cut-Off Date is approximately
months. Although little data is available, defaults on mortgage loans, including
mortgage loans similar to the Mortgage Loans, are generally expected to occur
with greater frequency in the early years of the terms of mortgage loans.
 
                             THE MORTGAGE LOAN POOL
 
GENERAL
 
     The Mortgage Loans to be transferred by the Depositor to the Trust Fund on
           , 199  (the "Startup Day") will consist of [       ] fixed-rate 
conventional home equity loans evidenced by promissory notes (the "Mortgage
Notes") secured by first- and second-priority mortgages and deeds of trust,
security deeds or mortgages, which are located in [               ] states [and
the District of Columbia]. The Mortgaged Properties securing the Mortgage Loans
consist of single-family residences (which may be detached, part of a
two-to-four family dwelling, a condominium unit, a mobile, manufactured or
modular home, a townhouse or a unit in a planned unit development). The
Mortgaged Properties may be owner-occupied (which includes second and vacation
homes) and non-owner occupied investment properties. All Mortgage Loans were
originated or purchased after                . Mortgage Loans aggregating [   %]
of the original aggregate loan balance are secured by first liens on the related
properties, and the remaining Mortgage Loans are secured by second liens on the
related properties. The "Loan Balance" of a Mortgage Loan (other than a
Liquidated Mortgage Loan) on any day is equal to its Cut-Off Date Loan Balance,
minus all collections applied in reduction of the Cut-Off Date Loan Balance of
such Mortgage Loan. The Loan Balance of a Liquidated Mortgage Loan (as defined
herein) after the Collection Period in which such Mortgage Loan becomes a
Liquidated Mortgage Loan shall be zero.
 
     The Loan-to-Value Ratios shown below were calculated based upon the
appraised values of the Mortgaged Properties at the time of origination (the
"Appraised Values").
 
     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 in general or in
any particular area has experienced or should experience an overall decline in
property values such that the outstanding balances of the Mortgage Loans,
together with the outstanding balances of any first mortgage, 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.
 
     No Loan-to-Value Ratio (based upon appraisals made at the time of
origination of the related Mortgage Loan) relating to any Mortgage Loan exceed
[     %] as of the Cut-Off Date. The Mortgage Loans are not insured by primary
mortgage insurance policies, nor does any pool insurance insure the Mortgage
Loans, however, certain distributions due to the holders of the Offered
Certificates are guaranteed by the Certificate Insurer in accordance with the
terms of the Certificate Insurance Policy. See "The Certificate Insurer and The
Certificate Insurance Policy." The Mortgage Loans are not guaranteed by the
Depositor, the Seller or any affiliate of the Depositor or the Seller.
                                       S-9
<PAGE>   72
 
     As of the Cut-Off Date, the average Loan Balance of the Mortgage Loans was
[$          ], the Loan Rates of the Mortgage Loans ranged from [     %] to
[     %], the weighted average combined Loan-to-Value Ratio of the Mortgage
Loans was [     %], the weighted average Loan Rate of the Mortgage Loans was
[     %], the weighted average remaining term to maturity of the Mortgage Loans
was [               ] months. The remaining terms to maturity of the Mortgage
Loans as of the Cut-Off Date ranged from [               ] months to 360 months.
The maximum Loan Balance of all Mortgage Loans, as of the Cut-Off Date, was
[$          ]. Mortgage Loans containing balloon payments represented
[$          ] of the aggregate Loan Balances as of the Cut-Off Date of the
Mortgage Loans. No Mortgage Loan matures after [               ]. The Trust Fund
consists of [               ] Mortgage Loans as of the Cut-Off Date, of which
[               ] are secured by first mortgages, security deeds or deeds of
trust and the remainder are secured by second mortgages, security deeds or deeds
of trust. As a percentage of the aggregate Loan Balances as of the Cut-Off Date
of Mortgage Loans, [     %] were secured by first mortgages or deeds of trust,
[     %] were secured by mortgages or deeds of trust on single-family dwellings,
[     %] were secured by mortgages or deeds of trust on two-to-four family
dwellings, [     %] were secured by mortgages or deeds of trust on condominium
units, [     %] were secured by mortgages or deeds of trust on mobile homes and
[     %] were secured by mortgages or deeds of trust on other types of
dwellings.

INTEREST PAYMENTS ON THE MORTGAGE LOANS
 
     The Mortgage Loans provide that interest is charged to the Mortgagors
thereunder, and payments are due from such Mortgagors, as of a scheduled day of
each month which is fixed at the time of origination. Scheduled monthly payments
made by the Mortgagors on the Mortgage Loans either earlier or later than the
scheduled due dates thereof will not affect the amortization schedule or the
relative application of such payments to principal and interest. All of the
Mortgage Loans provide for monthly installments of principal
                                      S-11
<PAGE>   74
 
and interest. Certain Mortgage Loans provide for full amortization of the
principal amount thereof over the term of the Mortgage Loan. Certain other
Mortgage Loans provide for amortization of the principal amount thereof over the
term of the Mortgage Loan and a balloon payment of the remaining principal
amount thereof at the end of the term of the Mortgage Loan.

     First Union National Bank is the Seller and Master Servicer under the
Pooling and Servicing Agreement. First Union National Bank is a national banking
association and a banking subsidiary of First Union Corporation, a North
Carolina corporation and a multi-bank holding company registered under the Bank
Holding Company Act. First Union Corporation is the           largest bank
holding company in the United States based on total assets as of December 31,
     .
 
     The Seller will sell and assign each Mortgage Loan to the Trust Fund in
consideration of the net proceeds from the sale of the Offered Certificates,
which are being offered hereby, and for the Class R Certificates.
 
     The Offered Certificates will not represent an interest in or obligation
of, nor are the Mortgage Loans guaranteed by the Seller, or any of its
affiliates.
 
     The Master Servicer may use a subservicer (the "Subservicer") in the
performance of the administrative and servicing obligations of the master
servicer under the Pooling and Servicing Agreement, but no such subservicing
arrangements will discharge the Master Servicer from its obligations under the
Pooling and Servicing Agreement. First Union Mortgage Corporation, a wholly
owned subsidiary of First Union Corporation, will initially act as the
Subservicer for all of the Mortgage Loans.
 
     The Trustee may remove the Master Servicer, and the Master Servicer may
resign, only in accordance with the terms of the Pooling and Servicing
Agreement. No removal or resignation shall become effective until the Trustee or
a successor servicer shall have assumed the Master Servicer's responsibilities
and obligations in accordance therewith.
 
     Any collections received by the Master Servicer after removal or
resignation shall be endorsed by it to the Trustee and remitted directly to the
Trustee.
 
CREDIT AND UNDERWRITING GUIDELINES
 
     The following is a description of the underwriting guidelines customarily
employed by the Seller with respect to home equity loans which it purchases or
originates. Each Mortgage Loan was underwritten according to these guidelines.
The Seller believes its standards are consistent with those utilized by home
equity lenders generally. The underwriting process is intended to assess both
the prospective borrower's ability to repay and the adequacy of the real
property security as collateral for the loan granted. In certain cases, loans
may be made outside of those guidelines with the prior approval of a
pre-designated senior official of the Seller.
 
     The Seller generally originates or purchases fixed rate loans which either
fully amortize over a period not to exceed 360 months if the lien is first
priority, otherwise 240 months or provide for amortization over a 360 month
schedule, have a maturity of 180 months and require a balloon payment at the
maturity date. The loan amounts generally range from a minimum of $10,000 to a
maximum of $500,000. The Seller originates or purchases non-purchase money first
or second mortgage loans. In addition, the Seller has programs for origination
of purchase money first mortgages.
 
     The homes used for collateral to secure the loans may be either primary
residential (which includes second and vacation homes) or investor owned one- to
four-family homes, condominiums, mobile, manufactured or modular homes or
townhouses. Commercial properties or agricultural land are not accepted as
collateral.
 
                                      S-12
<PAGE>   75
 
     The combined Loan-to-Value Ratio of the first and second mortgages
generally may not exceed      %. If a prior mortgage exists, the Seller first
reviews the first mortgage documentation. The Seller does not originate or
purchase loans where the first mortgage contains a shared appreciation clause.
 
     Each property proposed as security for a loan must be appraised. The
Seller's appraisal guidelines are at least as stringent as FNMA requirements.
 
     Each mortgage applicant must provide, and the Seller must verify, personal
financial information. [The applicant's total monthly obligations (which
includes principal and interest on each mortgage, tax assessments, other loans,
charge accounts and all other scheduled indebtedness) generally cannot exceed
     % of the applicant's gross monthly income. Applicants who are salaried
employees must provide current employment information in addition to   recent
years of employment history and the Seller verifies this information.
Verifications are based on written confirmation from employers or a combination
of the   most recent pay stubs, the   most recent years W-2 tax forms and
telephone confirmation from the employer. Self-employed applicants must be
self-employed in the same field for a minimum of   years. The self-employed
applicant must provide signed copies of complete federal income tax returns
(including schedules) filed for the most recent   years.]
 
     A credit report by an independent credit reporting agency is required
reflecting the applicant's complete credit history. The credit report should
reflect all delinquencies of [30] days or more, repossessions, judgments,
foreclosures, garnishments, bankruptcies, divorce actions and similar adverse
credit practices that can be discovered by a search of public records. If the
report is obtained more than [30] days prior to the loan closing, the lender
must determine that the reported information has not changed. Borrowers must
provide acceptable written explanations of any major delinquencies. Written
verification is obtained of the first mortgage balance, its status and whether
local taxes, interest, insurance and assessments are included in the applicant's
monthly payment. All taxes and assessments not included in the payment must be
verified as current.
 
     The Seller is responsible for using sound judgment in underwriting the
loans consistent with prudent industry practices. Generally, the applicant
should have an acceptable credit history given the amount of equity available,
the strength of the applicant's employment history and the level of the
applicant's income to debt obligations. The rescission period must have expired
prior to funding a loan. The rescission period may not be waived by the
applicant except as permitted by law. An ALTA title insurance policy is required
for all loans.
 
     The applicant is required to secure property insurance in an amount
sufficient to cover the new loan and any prior mortgage. If the sum of the
outstanding first mortgage, if any, and the home equity loan exceeds the policy
coverage limit, then the policy must provide guaranteed replacement cost
coverage. The Seller must ensure that its name and address is properly added to
the mortgagee clause of the insurance policy.
 
DELINQUENCY, LOAN LOSS AND FORECLOSURE INFORMATION
 
                  DELINQUENCY EXPERIENCE OF THE MORTGAGE LOANS
 
     The following table sets forth the Seller's delinquency experience, on its
entire servicing portfolio of mortgage loans similar to the Mortgage Loans at
the dates indicated below. The Seller's portfolio of mortgage loans may differ
significantly from the Mortgage Loans included in the Trust Fund in terms of
interest rates, principal balances, geographic distribution, Loan-to-Value
Ratios and other relevant characteristics. There can be no assurance the
delinquency and loss experienced on the Mortgage Loans [(most of which have been
acquired by the Seller during the past twelve months)] will be consistent with
the historical information
 
                                      S-13
<PAGE>   76
 
provided below. Such losses and delinquencies on the Mortgage Loans may be
higher than the historical information presented below.
 
                                    [TABLE]
 
                      LOAN LOSS AND FORECLOSURE EXPERIENCE
                             OF THE MORTGAGE LOANS
 
     From the time the Seller began originating mortgage loans similar to and
including the Mortgage Loans (approximately 12 months prior to the Cut-Off
Date), there have been no losses or foreclosures with respect to any such
mortgage loans as to which the Seller or an Affiliate has retained servicing.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
GENERAL
 
     The weighted average life of, and, if purchased at other than par
(disregarding, for purposes of this discussion, the effects on an investor's
yield resulting from the timing of the settlement date and those considerations
discussed below under "Payment Delay Feature of Certificates"), the yield to
maturity on, a Class of the Offered Certificates will relate to the rate of
payment of principal of the Mortgage Loans, including for this purpose
Prepayments, liquidations due to defaults, casualties and condemnations, and
repurchases of Mortgage Loans by the Seller. Substantially all the Mortgage
Loans may be prepaid by the related Mortgagors at any time without payment of
any prepayment fee or penalty. The actual rate of principal prepayments on pools
of mortgage loans is influenced by a variety of economic, tax, geographic,
demographic, social, legal and other factors and has fluctuated considerably in
recent years. In addition, the rate of principal prepayments may differ among
pools of mortgage loans at any time because of specific factors relating to the
mortgage loans in the particular pool, including, among other things, the age of
the mortgage loans, the geographic locations of the properties securing the
loans and the extent of the mortgagors' equity in such properties, and changes
in the mortgagors' housing needs, job transfers and unemployment. Generally,
however, because the Mortgage Loans bear interest at fixed rates, and the rate
of prepayment on fixed rate mortgage loans is sensitive to prevailing interest
rates, if prevailing interest rates fall significantly below the interest rates
on the Mortgage Loans, the Mortgage Loans are likely to be subject to higher
prepayment rates than if prevailing rates remain at or above the interest rates
on the Mortgage Loans. Conversely, if prevailing interest rates rise
significantly above the interest rates on the Mortgage Loans, the rate of
prepayments would be likely to decrease. Defaults on mortgage loans are expected
to occur with greater frequency in the early years of the mortgage loan term.
Although little data is available with respect to the rate of default on second
mortgage loans, it is generally expected that the rate of default on second
mortgage loans may be greater than that of mortgage loans secured by first
priority liens on comparable properties.
 
     In addition to the foregoing factors affecting the weighted average life of
each Class of the Offered Certificates, the provisions of the Pooling and
Servicing Agreement result in a limited acceleration of the Offered Certificates
relative to the amortization of the related Mortgage Loans in early months of
the transaction. The accelerated amortization is achieved by the application of
certain excess interest to the payment of the Class A Principal Balance. This
acceleration feature creates overcollateralization which results from the excess
of the Aggregate Loan Balance over the Class A Principal Balance. Once the
required level of overcollateralization is reached, the acceleration feature
will cease, unless necessary to maintain the required level of
overcollateralization.
 
     As indicated above, if purchased at other than par, the yield to maturity
on an Offered Certificate will be affected by the rate of the payment of
principal of the Mortgage Loans. If the actual rate of payments on the Mortgage
Loans is slower than the rate anticipated by an investor who purchases an
Offered Certificate at a discount, the actual yield to such investor will be
lower than such investor's anticipated yield. If the actual rate of payments on
the Mortgage Loans is faster than the rate anticipated by an investor who
purchases an
 
                                      S-14
<PAGE>   77
 
Offered Certificate at a premium, the actual yield to such investor will be
lower than such investor's anticipated yield.
 
WEIGHTED AVERAGE LIVES
 
     Greater than anticipated prepayments of principal will increase the yield
on Offered Certificates purchased at a price less than par. Greater than
anticipated prepayments of principal will decrease the yield on Offered
Certificates purchased at a price greater than par. The effect on an investor's
yield due to principal prepayments on the Mortgage Loans occurring at a rate
that is faster (or slower) than the rate anticipated by the investor in the
period immediately following the issuance of the Certificates will not be
entirely offset by a subsequent like reduction (or increase) in the rate of
principal payments. The weighted average life of the Offered Certificates will
also be affected by the amount and timing of delinquencies and defaults on the
Mortgage Loans and the recoveries, if any, on defaulted Mortgage Loans and
foreclosed properties.
 
     The "Weighted Average Life" of a Certificate refers to the average amount
of time that will elapse from the date of issuance to the date each dollar in
respect of principal of such Certificate is repaid. The weighted average life of
any Class of the Class A Certificates will be influenced by, among other
factors, the rate at which principal payments are made on the Mortgage Loans,
including final payments made upon the maturity of balloon payment Mortgage
Loans.
 
     Prepayments on Mortgage Loans are commonly measured relative to a
prepayment standard or model. The model used in this Prospectus Supplement is
the prepayment assumption (the "Prepayment Assumption"), which represents an
assumed rate of prepayment each month relative to the then outstanding principal
balance of the pool of mortgage loans for the life of such mortgage loans. A
100% Prepayment Assumption assumes a conditional prepayment rate ("CPR") of
     % per annum of the outstanding principal balance of such mortgage loans in
the first month of the life of the mortgage loans and an additional      %
(precisely        ) (expressed as a percentage per annum) in each month
thereafter until the twelfth month and in each month thereafter during the life
of the mortgage loans, a conditional prepayment rate of      % per annum each
month is assumed. As used in the table below, 0% Prepayment Assumption assumes a
conditional prepayment rate equal to 0% of the Prepayment Assumption, i.e., no
prepayments. Correspondingly, 80% Prepayment Assumption assumes prepayment rates
equal to 80% of the Prepayment Assumption, and so forth. The Prepayment
Assumption does not purport to be a historical description of prepayment
experience or a prediction of the anticipated rate of prepayment of any pool of
mortgage loans, including the Mortgage Loans. The Depositor 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.
 
     Since the tables were prepared on the basis of the assumptions in the
following paragraph, there are discrepancies between characteristics of the
actual Mortgage Loans and the characteristics of the Mortgage Loans assumed in
preparing the tables. Any such discrepancy may have an effect upon the
percentages of the Loan Balances outstanding and weighted average lives of the
Offered Certificates set forth in the tables. In addition, since the actual
Mortgage Loans in the Trust Fund have characteristics which differ from those
assumed in preparing the tables set forth below, the distributions of principal
on the Offered Certificates may be made earlier or later than as indicated in
the tables.
 
     For the purpose of the tables below, it is assumed that: (i) the Mortgage
Loans consist of pools of loans with the level-pay and balloon amortization
characteristics set forth below, (ii) the Closing Date for the Class A
Certificates is             ,           (iii) distributions on the Class A
Certificates are made on the      day of each month regardless of the day on
which the Distribution Date actually occurs, commencing in           and are
made in accordance with the priorities described herein, (vi) the scheduled
monthly payments of principal and interest on the Mortgage Loans will be timely
delivered on the first day of each month (with no defaults), commencing in
          , (v) the Mortgage Loans' prepayment rates are a multiple of the
Prepayment Assumption, (vi) all prepayments are prepayments in full received on
the last day of each month (commencing           ) and include 30 days' interest
thereon, (vii) no optional termination is exercised, (viii) the Class A
Certificates of each Class have the respective Certificate Rates and initial
 
                                      S-15
<PAGE>   78
 
Class A Principal Balances as set forth herein, and (ix) the
overcollateralization levels are set initially as specified in the Pooling and
Servicing Agreement, and thereafter decrease in accordance with the provisions
of the Pooling and Servicing Agreement.
 
                                    [TABLE]
 
     Subject to the foregoing discussion and assumptions, the following table
indicates the weighted average life of each Class A Certificates, and sets forth
the initial Class A Principal Balance of each such Class of Class A Certificates
that would be outstanding after each of the dates shown at various percentages
of Prepayment Assumption.
 
            PERCENT OF INITIAL CLASS A PRINCIPAL BALANCE OUTSTANDING
           AT THE FOLLOWING PERCENTAGES OF THE PREPAYMENT ASSUMPTION
 
                                    [TABLE]
 
     This table has been prepared based on the assumptions described above
(including the assumptions regarding the characteristics and performance of the
Mortgage Loans, which differ from the actual characteristics and performance
thereof) and should be read in conjunction therewith.
 
MANDATORY PREPAYMENT
 
     On the Closing Date, a portion of the proceeds of the sale of the
Certificates equal to $       (the "Pre-Funded Amount") will be deposited in a
trust account in the name of the Trustee (as defined herein) (the "Pre-Funding
Account"). The approximate original Pre-Funded Amount of $       will be funded
from the proceeds of the sale of Class A Certificates and will be used to
acquire Subsequent Mortgage Loans, if available. In the event that, on
          , 1999, not all of the approximately $       funded from the sale of
the Certificates has been used to acquire Subsequent Mortgage Loans, then the
Class or Classes of Class A Certificates then entitled to receive payments of
principal will receive a partial prepayment on the           , 1999 Distribution
Date in an amount equal to the amount remaining in the Pre-Funded Account
(taking into account the purchase of Subsequent Mortgage Loans on such date).
 
     Although no assurance can be given, the Seller intends that the principal
amount of Subsequent Mortgage Loans sold to the Trust Fund will require the
application of substantially all the amount on deposit in the Pre-Funding
Account and that there should be no material principal prepaid to the holders of
any of the Class A Certificates.
 
PAYMENT DELAY FEATURE OF CERTIFICATES
 
     Pursuant to the Pooling and Servicing Agreement, an amount equal to
mortgagor payments with respect to each Mortgage Loan (net of the Servicing Fee)
received by the Master Servicer during each Collection Period is to be remitted
to the Trustee on or prior to the Business Day immediately preceding the related
Distribution Date; the Trustee will be required to distribute such amounts to
the Owners on the next succeeding Distribution Date. As a result, the monthly
distributions to the Owners generally reflect mortgagor payments during the
prior calendar month, and the first Distribution Date will not occur until
            , 199  . Thus, the effective yield to the Owners will be below that
otherwise produced by the applicable Certificate Rate because the distributions
to Certificateholders in respect of any given month will not be made until on or
about the      day of the following month.
 
ACCELERATED PRINCIPAL DISTRIBUTION AMOUNT
 
     The provisions of the Pooling and Servicing Agreement result in a limited
acceleration of the Offered Certificates relative to the amortization of the
related Mortgage Loans in early months of the transaction. The accelerated
amortization is achieved by the application of certain excess interest to the
payment of the Class A Principal Balance. This acceleration feature creates
overcollateralization which results from the excess of the Aggregate Loan
Balance over the Class A Principal Balance. Once the required level of
overcollateralization is
 
                                      S-16
<PAGE>   79
 
reached, the acceleration feature will cease, unless necessary to maintain the
required level of overcollateralization. As used herein, "Aggregate Loan
Balance" means, as of any date of determination, the aggregate of the Loan
Balances, as of such date.
 
              FORMATION OF THE TRUST FUND AND TRUST FUND PROPERTY
 
     On           , 1999, the FURST Home Equity Loan Trust Fund 1999-  will be
created and established pursuant to the Pooling and Servicing Agreement. On such
date, the Depositor will convey without recourse (subject to certain obligations
to repurchase Defective Mortgage Loans or replace Defective Mortgage Loans with
Eligible Substitute Mortgage Loans) the Mortgage Loans to the Trust Fund and the
Trust Fund will issue (a) the Offered Certificates and (b) the Class R
Certificates to the Seller.
 
     The property of the Trust Fund shall include (a) the Mortgage Loans (other
than certain payments received thereon on or prior to the Cut-Off Date) together
with the related Mortgage Loan documents (including any guaranty executed in
connection therewith) and the Seller's interest in any property which secures a
Mortgage Loan (the "Mortgaged Property") and all payments thereon and proceeds
of the conversion, voluntary or involuntary, of the foregoing, (b) such amounts
as may be held in the Distribution Account, the Collection Account and the
Pre-Funding Account, (c) the Certificate Insurance Policy and (d) proceeds of
all the foregoing (including, but not by way of limitation, all, of any mortgage
insurance, hazard insurance and title insurance policy relating to the Mortgage
Loans, cash proceeds, accounts, accounts receivable, notes, drafts, acceptances,
chattel paper, checks, deposit accounts, rights to payment of any and every
kind, and other forms of obligations and receivables which at any time
constitute all or part of or are included in the proceeds of any of the
foregoing) to pay the Certificates as specified in the Pooling and Servicing
Agreement.
 
     The Certificates will not represent an interest in or an obligation of, nor
will the Mortgage Loans be guaranteed by, the Depositor, the Seller, the Master
Servicer or any of their affiliates.
 
     In addition to the Offered Certificates, the Trust Fund will also issue a
residual class entitled "               , Class R Certificates" (the "Class R
Certificates") which will be designated as the residual interest in the REMIC
for purposes of the Code. The Class R Certificates will be issued to the Seller
and to the Trustee, in its capacity as tax matters person, and are not being
offered hereby. The Certificates are herein referred to as the Certificates.
 
     Prior to its formation the Trust Fund will have had no assets or
obligations. Upon formation, the Trust Fund will not engage in any business
activity other than acquiring, holding and collecting payments on the Mortgage
Loans, issuing the Certificates and distributing payments thereon. The Trust
Fund will not acquire any receivables or assets other than the Mortgage Loans
and the rights appurtenant thereto. To the extent that borrowers make scheduled
payments under the Mortgage Loans, the Trust Fund will have sufficient liquidity
to make distributions on the Certificates. As the Trust Fund does not have any
operating history and will not engage in any business activity other than
issuing the Certificates and making distributions thereon, there has not been
included any historical or pro forma ratio of earnings to fixed charges with
respect to the Trust Fund.
 
                        DESCRIPTION OF THE CERTIFICATES
 
     The Certificates will be issued pursuant to the Pooling and Servicing
Agreement among the Depositor, the Seller, the Master Servicer and the Trustee.
Reference is made to the Prospectus for additional information regarding the
terms and conditions of the Pooling and Servicing Agreement to the extent not
revised by the following description. To the extent that the statements in this
Prospectus Supplement modify statements in the Prospectus, the statements in
this Prospectus Supplement control.
 
     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 and Servicing Agreement. When particular provisions or terms used in the
Pooling and Servicing Agreement are referred to, the actual provisions
(including definitions of terms) are incorporated by reference. General
 
                                      S-17
<PAGE>   80
 
     Each Offered Certificate will represent certain undivided, fractional
ownership interests in the Trust Fund created and held pursuant to the Pooling
and Servicing Agreement, subject to the limits and the priority of distribution
described therein. The Class R Certificates will represent the entire interest
in the assets of the Trust Fund other than that represented by the Offered
Certificates and shall be issued to the Seller.
 
     On the Closing Date, upon the order of the Depositor concurrently with the
sale and assignment to the Trustee of the Trust Fund assets, the Trustee will
execute, deliver and authenticate the Certificates. The Class A Certificates
will be issued in minimum dollar denominations of $          and integral dollar
multiples in excess thereof (with one Class A Certificate issued in an amount
less than $          , if necessary, so that outstanding Class A Certificates
will equal the Original Class A Certificate Principal Balance).
 
ASSIGNMENT OF MORTGAGE LOANS
 
     At the time of issuance of the Offered Certificates, the Depositor will
assign to the Trustee all of its right, title and interest in and to the
Mortgage Loans, including all payments of interest and principal, from whatever
source derived, which are received on or with respect to the Mortgage Loans on
or after the Cut-Off Date, together with the other assets included in the Trust.
In addition, on or prior to the date the Offered Certificates are initially
issued by the Trust Fund, the Master Servicer will cause the Certificate
Insurance Policy to be delivered to the Trustee. Concurrently with such
assignment, the Trustee will deliver the Certificates to the Depositor in
exchange for, and in an aggregate principal amount equal to, the Pool Balance as
of the Cut-Off Date. Each Mortgage Loan will be identified in a schedule
delivered to the Trustee.
 
     Under the terms of the Pooling and Servicing Agreement, the Seller will
deliver the Mortgages, the Mortgage Notes and the other Related Documents to
First Union National Bank, Trust Fund Department, as Document Custodian, and, so
long as the Seller's long-term unsecured debt is rated above [A3] by Moody's
Investors Service Inc. ("Moody's") and [A-] by Standard and Poor's Rating
Services, a division of The McGraw-Hill Companies, Inc. ("S&P") and no other
assignment event shall have occurred and be continuing, the Document Custodian
shall be entitled to maintain possession of the documentation relating to each
Mortgage Loan (the "Mortgage Files"). In the event that the Seller's long-term
unsecured debt rating does not satisfy the above-described standards or another
assignment event has occurred and is continuing, the Seller will cause as soon
as practicable the Mortgage Files pertaining to each such Mortgage Loan to be
delivered to the Trustee or the Trustee's bailee. The Document Custodian (but
only if it is not the Seller or any Affiliate of the Seller), will review such
Mortgage Files within the period specified in the Pooling and Servicing
Agreement and notify the Trustee of any material defect discovered in such
review. Notwithstanding the foregoing, the Document Custodian shall perform the
review required by Section      of the Pooling and Servicing Agreement only as
to each Mortgage Note within 60 days from the (i) the Closing Date with respect
to Mortgage Notes delivered on or before the Closing Date and (ii) the date a
Mortgage Note is delivered, if delivered after the Closing Date. If any document
required to be included in any Mortgage File does not bear manual signatures,
has not been received or is unrelated to the applicable Mortgage Loan, and such
defect is not cured as provided in the Pooling and Servicing Agreement following
receipt of notification thereof to the Seller by the Trustee, the Seller will be
required either to repurchase or to replace the affected Mortgage Loan in the
manner set forth below. In the Pooling and Servicing Agreement,
as trustee of Trust Fund will acknowledge the assignment of the Mortgage Loans
to the Trust Fund and the Seller will agree to hold the Mortgage Files of the
Loans for and on behalf of the Trust Fund for so long as the Mortgage Loans are
owned by the Trust Fund.
 
     The Seller will make certain representations and warranties with respect to
each Mortgage Loan. In the event there is a breach of any representation or
warranty made by the Seller in the Pooling and Servicing Agreement as to a
Mortgage Loan that materially and adversely affects the interest of the
Certificateholders or the Certificate Insurer, the Seller will be required
either to (i) repurchase the related Mortgage Loan from the Trust Fund or (ii)
prior to the expiration of two years following the date the Offered Certificates
are initially issued, to substitute therefor an Eligible Substitute Mortgage
Loan, in each case in the manner described below.
 
                                      S-18
<PAGE>   81
 
     Any Mortgage Loan required to be repurchased by the Seller as a result of a
defect, omission or breach of representation or warranty will be repurchased at
the applicable Purchase Price. The Purchase Price will be deposited into the
Collection Account on the second Business Day next preceding the Distribution
Date following expiration of the related cure period.
 
     As to any Eligible Substitute Mortgage Loan, the Seller will deposit into
the Collection Account the amount, if any, by which the conveyed balance of such
Eligible Substitute Mortgage Loan at the end of the Collection Period in which
the events giving rise to the related substitution occurred is less than the
Loan Balance of the related Mortgage Loan being removed from the Trust Fund at
the end of such Collection Period (the "Substitution Adjustment Amount"). The
Seller will substitute any Eligible Substitute Mortgage Loan, and deposit any
such Substitution Adjustment Amount into the Collection Account, on the Business
Day next preceding the Distribution Date in the month following such Collection
Period. Upon substitution, an Eligible Substitute Mortgage Loan will be subject
to the terms of the Pooling and Servicing Agreement and the Seller will be
deemed to have made, with respect to such Eligible Substitute Mortgage Loan, as
of the date of substitution, the representations and warranties made by the
Seller with respect to all other Mortgage Loans in the Trust Fund. Upon receipt
by the Trustee of written notification of any such repurchase or substitution,
subject to certain conditions set forth in the Pooling and Servicing Agreement,
the Document Custodian will execute and deliver an instrument of transfer or
assignment necessary to vest in the Seller legal and beneficial ownership of the
Loan Balance of such Mortgage Loan (including any property acquired in respect
thereof or proceeds of any insurance policy with respect thereto). The
obligation of the Seller to repurchase or replace any such Loan Balance will be
the sole remedy against the Seller available to Certificateholders or the
Trustee.
 
     An Eligible Substitute Mortgage Loan is a Mortgage Loan that, as of the
substitution date, (i) has an outstanding Loan Balance equal to or less than the
Loan Balance of the Defective Mortgage Loan it replaces as of the substitution
date; (ii) has a Loan Rate not less than the current Loan Rate of such Defective
Mortgage Loan and not more than one percent in excess thereof; (iii) comply with
each representation and warranty set forth in the Pooling and Servicing
Agreement (deemed to be made as of the date of substitution); (iv) has a
remaining term to maturity not later than nor more than six months earlier than
the remaining term to maturity of such Defective Mortgage Loan; (v) has an
original Combined Loan-to-Value Ratio not greater than the Defective Mortgage
Loan, in the case of an Eligible Substitute Mortgage Loan that replaces a
Mortgage Loan that has a ratio of the Original Loan Balance for such Eligible
Substitute Mortgage Loan together with the outstanding unpaid principal balance
of the related mortgage loans with higher or equal priority to the Appraised
Value of the related Mortgaged Property at the time such Eligible Substitute
Mortgage was originated of not more than [     %]; (vi) has an Original Loan
Balance of not more than $          ; and (vii) has a Mortgage in a lien
position of the same or higher level of priority as the Mortgage of such
Defective Mortgage Loan. More than one Eligible Substitute Mortgage Loan may be
substituted for a Defective Mortgage Loan if such Eligible Substitute Mortgage
Loans meet the foregoing attributes in the aggregate and such substitution is
approved in writing in advance by the Rating Agencies.
 
     In the event the Seller repurchases or substitutes a Mortgage Loan as
provided above, there will be delivered to the Trustee an opinion of counsel as
to whether the repurchase or substitution (i) will be subject to tax as a result
of being deemed a prohibited transaction under section 860F(a)(2) of the Code;
(ii) will be deemed a contribution to the REMIC after the startup day that would
give rise to the tax specified under section 860G(d)(1) of the Code; or (iii)
will cause the Trust Fund to fail to qualify as a REMIC at any time any
Certificate is outstanding. The Seller will not be required to repurchase or
replace any Defective Mortgage Loan in the event such repurchase or replacement,
as evidenced by such opinion, would result in the imposition of a prohibited
transaction tax or be deemed a contribution to the REMIC after the startup day,
unless the Master Servicer has determined that there is an actual or imminent
default by the borrower with respect to the affected Mortgage Loan. The Seller
will not be required or permitted to repurchase or replace any Defective
Mortgage Loan if such repurchase or replacement, as evidenced by such opinion,
will cause the Trust Fund to fail to qualify as a REMIC.

     Mortgage Loans required to be repurchased or substituted by the Seller as
described in the preceding paragraph as a result of a defect, omission or breach
of a representation or warranty are referred to herein as "Defective Mortgage
Loans."
 
     In the event any such repurchase results in a prohibited transaction tax,
such tax is required to be charged first against amounts otherwise distributable
to the Class R Certificateholders and second, to the extent such amounts are
insufficient, against amounts otherwise distributable to the Holders of the
Offered Certificates, in each case on a pro rata basis among Certificateholders
of the applicable Class.
 
PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO COLLECTION AND DISTRIBUTION ACCOUNTS
 
     Collection Account.  The Master Servicer will, upon the occurrence and
continuance of the failure of any of the events described in clauses (i) or (ii)
of the following paragraph, establish and maintain in the name of the Trustee
with an entity meeting the requirements of the definition of "Eligible Account,"
a separate trust account (the "Collection Account") for the benefit of the
holders of the Certificates. Upon receipt by the Master Servicer of amounts in
respect of the Mortgage Loans (excluding amounts representing unreimbursed
advances, the Servicing Fee, Foreclosure Profits, fees or late charge penalties
payable by Mortgagors, amounts received by the Master Servicer for the accounts
of Mortgagors for application towards the payment of taxes, insurance premiums,
assessments and similar items and Payaheads received during such Collection
Period intended for application in subsequent Collection Periods), the Master
Servicer will deposit such amounts in the Collection Account. Amounts so
deposited may be invested in Eligible Investments (as described in the Pooling
and Servicing Agreement) maturing no later than one Business Day prior to the
date on which the amount on deposit therein is required to be deposited in the
Distribution Account or on such Distribution Date if approved by the Rating
Agencies, the Trustee and the Certificate Insurer. The Master Servicer shall
retain all Foreclosure Profits.
 
     The Trustee will establish an account (the "Distribution Account") into
which will be deposited amounts withdrawn from the Collection Account for
distribution to Certificateholders on a Distribution Date or, if the Master
Servicer is not required to make deposits to the Collection Account, amounts
received from the Master Servicer. The Distribution Account will be an Eligible
Account.
 
     An "Eligible Account" is an account that is (i) maintained with a
depository institution whose debt obligations at the time of any deposit therein
have the highest short-term debt rating by the S&P and are rated P-1 by Moody's,
(ii) one or more accounts with a depository institution which accounts are fully
insured by either the Savings Association Insurance Fund ("SAIF") or the Bank
Insurance Fund ("BIF") of the Federal Deposit Insurance Corporation established
by such fund with a minimum long-term unsecured debt rating of Baa3 by Moody's
and BBB by S&P, (iii) a segregated trust account maintained with the corporate
trust departments of (A) the Trustee or an affiliate of the Trustee in its
fiduciary capacity or (B) an institution with capital and surplus of not less
than $50,000,000 and with a minimum long-term secured debt rating of Baa3 by
Moody's and BBB by S&P or (iv) otherwise acceptable to each Rating Agency and
the Certificate Insurer as evidenced by a letter from each Rating Agency and the
Certificate Insurer to the Trustee, without reduction or withdrawal of their
then current ratings of the Certificates.
 
     Notwithstanding anything in the Pooling and Servicing Agreement to the
contrary, (i) for so long as (A) the Master Servicer remains an Affiliate of the
Seller, (B) no Event of Default shall have occurred and be continuing and (C)
the Seller maintains a short-term rating of at least A-1 by S&P and P-1 by
Moody's, and for five Business Days following any reduction in either such
rating, or (ii) following the occurrence and continuation of certain events
described in the Pooling and Servicing Agreement, an arrangement is established
that is satisfactory to the Rating Agencies and the Certificate Insurer and
which does not in itself result in any reduction of (I) any rating issued in
respect of the Offered Certificates or (II) any reduction below investment grade
of the Offered Certificates without the benefit of the Certificate Insurance
Policy, the Master Servicer need not establish or make the daily deposits to the
Collection Account as provided herein, but may make a single deposit in the
Distribution Account in immediately available funds not later than 12:00 noon,
New York City time, on the second Business Day immediately preceding a
Distribution Date in a net
 
                                      S-20
<PAGE>   83
 
amount equal to the amount that would have been on deposit with respect to the
immediately preceding Collection Period in the Collection Account.
 
ADVANCES
 
     Not later than two Business Days prior to each Distribution Date, the
Master Servicer will remit to the Trustee for deposit in the Distribution
Account an amount, to be distributed on the related Distribution Date, equal to
the sum of the interest accrued on each Mortgage Loan through the related Due
Date but not received by the Master Servicer as of the close of business on the
last day of the related Collection Period and not previously advanced (net of
the Servicing Fee) (the "Monthly Advance"). Such obligation of the Master
Servicer continues with respect to each Mortgage Loan until such Mortgage Loan
becomes a Liquidated Mortgage Loan.
 
     In the course of performing its servicing obligations, the Master Servicer
will pay all reasonable and customary "out-of-pocket" costs and expenses
incurred in the performance of its servicing obligations, including, but not
limited to, the cost of (i) the preservation, restoration and protection of the
Mortgaged Properties, (ii) any enforcement or judicial proceedings, including
foreclosures, and (iii) the management and liquidation of Mortgaged Properties
acquired in satisfaction of the related Mortgage. Each such expenditure will
constitute a "Servicing Advance."
 
     The Master Servicer's right to reimbursement for Servicing Advances is
limited to late collections on the related Mortgage Loan, including Liquidation
Proceeds, related Mortgaged Property proceeds, Insurance Proceeds and such other
amounts as may be collected by the Master Servicer from the related Mortgagor or
otherwise relating to the Mortgage Loan in respect of which such unreimbursed
amounts are owed. The Master Servicer's right to reimbursement for Monthly
Advances shall be limited to late collections of interest on any Mortgage Loan
and to Liquidation Proceeds and Insurance Proceeds on the related Mortgage Loan.
The Master Servicer's right to such reimbursements is prior to the rights of
Certificateholders.
 
     Notwithstanding the foregoing, the Master Servicer is not required to make
any Monthly Advances or Servicing Advance if in the good faith judgment and sole
discretion of the Master Servicer, the Master Servicer determines that such
advance will not be ultimately recoverable from collections received from the
Mortgagor in respect of the related Mortgage Loan or other recoveries in respect
of such Mortgage Loan (a "Nonrecoverable Advance"). However, if any Servicing
Advance or Monthly Advance is determined by the Master Servicer to be
nonrecoverable from such sources, the amount of such Nonrecoverable Advance may
be reimbursed to the Master Servicer from other amounts on deposit in the
Collection Account.
 
DEPOSITS TO THE DISTRIBUTION ACCOUNT
 
     No later than two Business Days prior to each Distribution Date, the
following amounts in respect of the previous Collection Period shall be
deposited into the Distribution Account and shall constitute the "Available
Funds" for such Distribution Date: (i) (a) payment of principal and interest on
the Mortgage Loans received during such Collection Period (net of amounts
representing the Servicing Fee with respect to each Mortgage Loan, reimbursement
for related Monthly Advances and Servicing Advances, and Payaheads received
during such Collection Period intended for application in subsequent Collection
Periods) and (b) Payaheads received in prior Collection Periods intended for
application in such Collection Period; (ii) Net Liquidation Proceeds received
during such Collection Period; (iii) the Purchase Price for repurchased
Defective Mortgage Loans and any Substitution Adjustments Amounts in respect of
such Collection Period; (iv) payments from the Master Servicer in connection
with (a) Monthly Advances and (b) the termination of the Trust Fund with respect
to the Mortgage Loans as provided in the Pooling and Servicing Agreement, and
(v) any amounts paid under the Certificate Insurance Policy.
 
     A "Payahead" is a required monthly payment received by the Master Servicer
with the required monthly payment for the current Due Date, intended by the
related Mortgagor to be applied on a subsequent Due Date (for example, because
the Mortgagor intends to be on vacation the following month). Payaheads will be
held by the Master Servicer until deposited to the Distribution Account as part
of the Available Funds for the
 
                                      S-21
<PAGE>   84
 
Collection Period in which the Due Date that the Mortgagor designates for the
application of such required monthly payment occurs.

     Concurrently with each distribution to the Certificateholders, the Trustee
will forward to each Certificateholder a statement (based solely on information

          (ix) the Aggregate Class A Principal Balance after giving effect to
     payments allocated to principal above;
 
          (x) the amount of overcollateralization as of the close of business on
     the Distribution Date, after giving effect to distributions of principal on
     such Distribution Date;
 
          (xi) the number and aggregate Loan Balances of the Mortgage Loans as
     to which the minimum monthly payment is delinquent for 30-59 days, 60-89
     days and 90 or more days, respectively, as of the end of the preceding
     Collection Period;
 
          (xii) the book value of any real estate which is acquired by the Trust
     Fund through foreclosure or grant of deed in lieu of foreclosure;
 
          (xiii) the aggregate amount of Prepayments received on the Mortgage
     Loans during the previous Collection Period;
 
          (xiv) the aggregate amount of scheduled principal payments received on
     the Mortgage Loans during the previous Collection Period;
 
          (xv) the weighted average maturity of the Mortgage Loans as of the
     first day of the month prior to the Distribution Date; and
 
          (xvi) the weighted average Loan Rate on the Mortgage Loans as of the
     first day of the month prior to the Distribution Date.
 
     In the case of information furnished pursuant to clauses (ii) and (iii)
above, the amounts shall be expressed as a dollar amount per Certificate with a
$1,000 denomination.
 
     Within 60 days after the end of each calendar year, the Trustee will
forward to each Person, if requested in writing by such Person, who was a
Certificateholder during the prior calendar year a statement containing the
information set forth in clauses (ii) and (iii) above aggregated for such
calendar year.

DISTRIBUTIONS TO CERTIFICATEHOLDERS
 
     Priority of Distributions.  On each Distribution Date the Trustee shall
withdraw from the Distribution Account the Available Funds (the "Available
Funds"), and make distributions thereof as described below and to the extent of
the Available Funds:
 
          A. With respect to the Offered Certificates, the Available Funds in
     the following order of priority:
 
             (i) to the Trustee, the Trustee fee for such Distribution Date;
 
             (ii) to holders of each Class of Certificates, an amount equal to
        the related Class Interest Distribution for such Distribution Date;
 
             (iii) sequentially to the Certificateholders until the respective
        Class A Principal Balance of each such Class is reduced to zero, the
        related Class A Principal Distribution (other than the portion
        constituting the Distributable Excess Spread) for such Distribution
        Date; provided, however, after the occurrence and continuance of a
        Certificate Insurer Default, such portion of the Class A Principal
        Distribution for the Class A Certificates will be distributed pro rata
        to the holders thereof based on the respective Class A Principal
        Balances;
 
             (iv) to the Certificate Insurer, the amount owing to the
        Certificate Insurer under the Insurance Agreement for the premium
        payable; and
 
             (v) sequentially to the Certificateholders until the respective
        Class A Principal Balance of each such Class is reduced to zero, the
        related Distributable Excess Spread for such Distribution Date;
        provided, however, after the occurrence and continuance of a Certificate
        Insurer Default, such Distributable Excess Spread will be distributed
        pro rata to the holders thereof based on the respective Class A
        Principal Balances.
 
          B. After making the distributions referred to in subclause A above,
     the Trustee shall make distributions in the following order of priority, to
     the extent of the balance of the Amount Available:
 
             (i) to the Certificate Insurer, amounts owing to the Certificate
        Insurer for reimbursement for prior draws made on the Certificate
        Insurance Policy;
 
             (ii) to the Certificate Insurer, any other amounts owing to the
        Certificate Insurer under the Insurance Agreement; and
 
             (iii) to the Class R Certificateholders, the balance.
 
INTEREST
 
     On each Distribution Date, to the extent of funds available therefor in
accordance with the priorities described above under "-- Priorities of
Distributions," interest will be distributed to each Class of Senior
Certificates in an amount equal to the related Class Interest Distribution. For
each Distribution Date and each Class of Senior Certificates, the "Class
Interest Distribution" is the sum of (a) one month's interest at the related
Certificate Rate on the related Class A Principal Balance immediately prior to
such Distribution Date (the "Class Monthly Interest Distributable Amount") and
(b) any Class Interest Carryover Shortfall. The "Class A Principal Balance" as
of any Determination Date will be equal to the sum of the Principal Balances of
the Classes of Class A Certificates as of such date. As to any Distribution Date
and Class of Class A Certificates (sometimes referred to herein as the "Senior
Certificates"), the "Class Interest Carryover Shortfall" is the sum of (a) the
excess of the related Class Interest Distributable Amount for the preceding
Distribution Date and any outstanding Class Interest Carryover Shortfall with
respect to such Class on such preceding Distribution Date, over the amount in
respect of interest that is actually distributed to such Class on such preceding
Distribution Date plus (b) interest on such excess, to the extent permitted by
law, at the related Certificate Rate. The rate (the "Certificate Rate") for each
Class of Offered Certificates is the percentage set forth on page vi of this
Prospectus Supplement.
 
                                      S-23
<PAGE>   86
 
     On each Distribution Date, the Class Interest Distribution for each Class
of Senior Certificates will be distributed on an equal priority and any
shortfall in the amount required to be distributed as interest thereon to each
such Class will be allocated between such Classes pro rata based on the amount
each such Class would have been distributed in the absence of such shortfall.
See "-- Crosscollateralization" below.
 
PRINCIPAL
 
     On each Distribution Date, to the extent of funds available therefor, in
accordance with the priorities described above under "-- Priorities of
Distributions," principal will be distributed to the holders of Class A
Certificates then entitled to distributions of principal in an amount equal to
the lesser of (A) the related Aggregate Class A Principal Balance and (B) the
related Class A Principal Distribution for such Distribution Date. "Class A
Principal Distribution" means, with respect to any Distribution Date, the sum of
the related Class A Monthly Principal Distributable Amount for such Distribution
Date and any Outstanding Class A Principal Carryover Shortfall as of the close
of business on the preceding Distribution Date.
 
     "Class A Monthly Principal Distributable Amount" means, with respect to any
Distribution Date, the amount equal to the sum of the following amounts (without
duplication) with respect to the immediately preceding Collection Period (as
defined below): (i) each payment of principal on a Mortgage Loan received by the
Master Servicer during such Collection Period, including all full and partial
principal prepayments, (ii) the Principal Balance as of the end of the
immediately preceding Collection Period of each Mortgage Loan that became a
Liquidated Mortgage Loan for the first time during the related Collection
Period, (iii) the portion of the Purchase Price allocable to principal of all
repurchased Defective Mortgage Loans with respect to such Collection Period,
(iv) any Substitution Adjustment Amounts received on or prior to the previous
Determination Date and not yet distributed and (v) related Excess Spread, if
any, up to the overcollateralization requirement in effect for such Distribution
Date (the "Distributable Excess Spread").
 
     "Outstanding Class A Principal Carryover Shortfall" means with respect to
any Distribution Date, the excess of the Class A Principal Distribution for the
preceding Distribution Date over the amount in respect of principal that is
actually distributed to the Class A Certificateholders on such preceding
Distribution Date.
 
     If the required level of overcollateralization is reduced below the then
existing amount of overcollateralization (described below) or if the required
level of overcollateralization is satisfied, the amount of the Class A Monthly
Principal Distributable Amount on the following Distribution Date will be
correspondingly reduced by the amount of such reduction or by the amount
necessary such that the overcollateralization will not exceed the required level
of overcollateralization after giving effect to the distribution in respect of
principal to be made on such Distribution Date.
 
     So long as a Certificate Insurer Default has not occurred and is
continuing, distributions of the Class Principal Distribution will be applied,
sequentially, to the distribution of principal to the Class A Certificates such
that no Class of Class A Certificates having a higher numerical designation is
entitled to distributions of principal until the Class A Principal Balance of
each such Class of Certificates having a lower numerical designation has been
reduced to zero. On any Distribution Date if a Certificate Insurer Default has
occurred and is continuing, the Class A Principal Distribution will be applied
to the distribution of principal of each such Class outstanding on a pro rata
basis in accordance with the Class A Principal Balance of each such Class.
 
     On each Distribution Date following a Certificate Insurer Default, net
losses realized in respect of Liquidated Mortgage Loans (to the extent such
amount is not covered by Available Funds or the crosscollateralization mechanics
described herein) will reduce the amount of overcollateralization, if any.
 
     "Collection Period" means, with respect to any Determination Date or
Distribution Date, the calendar month immediately preceding such Determination
Date or Distribution Date, as the case may be.
 
     A "Liquidated Mortgage Loan," as to any Distribution Date, is a Mortgage
Loan with respect to which the Master Servicer has determined, in accordance
with the servicing procedures specified in the Pooling and Servicing Agreement,
as of the end of the preceding Collection Period, that all Liquidation Proceeds
which it expects to recover with respect to such Mortgage Loan have been
recovered.
                                      S-24
<PAGE>   87
 
     "Excess Spread" means, with respect to any Distribution Date, the positive
excess, if any, of (x) Available Funds for such Distribution Date over (y) the
amount required to be distributed pursuant to subclause A items (i) through
(iv), set forth under the heading "Description of Certificates -- Priority of
Distributions" on such Distribution Date.
 
     A "Certificate Insurer Default" will occur in the event the Certificate
Insurer fails to make a payment required under the Policy or if certain events
of bankruptcy or insolvency occur with respect to the Certificate Insurer.
Overcollateralization Provisions
 
     The credit enhancement provisions of the Trust Fund result in a limited
acceleration of the Class A Certificates relative to the amortization of the
Mortgage Loans in the early months of the transaction. The accelerated
amortization is achieved by the application of Distributable Excess Spread to
principal distributions on the Class A Certificates. This acceleration feature
creates overcollateralization (i.e., the excess of the aggregate outstanding
Principal Balance of the Mortgage Loans and the amount of deposit in the
Pre-Funding Account over the Aggregate Class A Principal Balance). Once the
required level of overcollateralization is reached, and subject tot the
provisions described in the next paragraph, the acceleration feature will cease,
until necessary to maintain the required level of overcollateralization.
 
     The Pooling and Servicing Agreement provides that, subject to certain
floors, caps and triggers, the required level of overcollateralization may
increase or decrease over time. any decrease in the required level of
overcollateralization will occur only at the sole discretion of the Certificate
Insurer. Any such decrease will have the effect of reducing the amortization of
the Class A Certificates below what it otherwise would have been. Pre-Funding
Account
 
     On the Closing Date, the Pre-Funded Amount will be deposited in the
Pre-Funding Account, which account shall be in the name of and maintained by the
Trustee and shall be part of the Trust Fund and may be used to acquire
Subsequent Mortgage Loans. During the Funding Period, the Pre-Funded Amount will
be maintained in the Pre-Funding Account. The Pre-Funded Amount will be reduced
during the Funding Period by the amount thereof used to purchase Subsequent
Mortgage Loans in accordance with the Pooling and Servicing Agreement. Any
Pre-Funded Amount remaining at the end of the related Funding Period will be
distributed to the holders of the Class or Classes of Class A Certificates
entitled to receive principal distributions on the Distribution Date immediately
following the end of such Funding Period, thus resulting in a partial principal
prepayment of certain Classes of Class A Certificates. See "Prepayment and Yield
Considerations -- Mandatory Prepayment" in this Prospectus Supplement.
 
     Amounts on deposit in the Pre-Funding Account will be invested in Eligible
Investments. All interest and any other investment earnings on amounts on
deposit in the Pre-Funding Account will be deposited in the Distribution Account
prior to each Distribution Date during the Funding Period. The Pre-Funding
Account will not be an asset of the REMIC.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The principal servicing compensation to be paid to the Master Servicer (the
"Master Servicing Fee") and the SubServicers (the "SubServicing Fee") with
respect to each Collection Period in respect of their servicing activities
relating to the Certificates (the "Servicing Fees") will be retained by the
Master Servicer from collections of interest on the Mortgage Loans in the Trust
Fund at the time such collections are required to be deposited into the
Distribution Account (or the Collection Account, if the Master Servicer is
required to make deposits therein) and with respect to the Master Servicer, will
be equal to      % (the "Master Servicing Rate") per annum of the outstanding
Loan Balance of each such Mortgage Loan as of the first day of each such
Collection Period. With respect to the SubServicers, the compensation will be
equal to      % (the "SubServicing Fee Rate") per annum of the outstanding Loan
Balance of each Mortgage Loan as of the first day of each such Collection
Period. In addition, the Master Servicer will receive any net investment income
from the investment of funds in the Collection Account, if any, and the Trustee
will be entitled to any net investment income from the investment of funds in
the Distribution Account. All assumption fees and late payment charges, to the
extent collected from borrowers, shall be retained by the Master Servicer.
 
                                      S-25
<PAGE>   88
 
     The Master Servicer will pay certain ongoing expenses associated with the
Trust Fund and incurred by it in connection with its responsibilities under the
Pooling and Servicing Agreement, including, without limitation, payment of the
disbursements of the Trustee, any custodian appointed by the Trustee, the
Certificate Registrar and any paying agent. In addition, as indicated in the
preceding section, the Master Servicer will be entitled to reimbursement for
certain expenses incurred by it in connection with defaulted Mortgage Loans and
in connection with the restoration of Mortgaged Properties, such right of
reimbursement being prior to the rights of Certificateholders to receive any
Insurance Proceeds or Net Liquidation Proceeds.
 
     The Trustee will receive a fee (the "Trustee Fee") with respect to each
Collection Period computed at an annual rate equal to      % (the "Trustee Fee
Rate") per annum on the Loan Balance of each Mortgage Loan as of the first day
of each such Collection Period and, for any Distribution Date, the Trustee Fee
will be deducted from collections allocable to payments of interest received
during the related Collection Period.
 
REGISTRATION OF OFFERED CERTIFICATES
 
     The Offered Certificates will initially be registered in the name of Cede,
the nominee of DTC. DTC 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 New York Uniform Commercial
Code, and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the 1934 Act. DTC accepts securities for deposit from its participating
organizations ("Participants") and facilitates the clearance and settlement of
securities transactions between Participants in such securities through
electronic book-entry changes in accounts of Participants, thereby eliminating
the need for physical movement of certificates. Participants include securities
brokers and dealers, banks and trust companies and clearing corporations and may
include certain other organizations. Indirect access to the DTC system is also
available to others such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly.
 
     Certificate owners (the "Certificate Owners") who are not Participants but
desire to purchase, sell or otherwise transfer ownership of Offered Certificates
may do so only through Participants (unless and until Definitive Offered
Certificates, as defined below, are issued). In addition, Certificate Owners
will receive all distributions of principal of and interest on the Offered
Certificates from the Trustee through DTC and Participants. Certificate Owners
will not receive or be entitled to receive certificates representing their
respective interests in the Offered Certificates, except under the limited
circumstances described below.
 
     Unless and until Definitive Offered Certificates (as defined below) are
issued, it is anticipated that the only "Certificateholder" of the Offered
Certificates will be Cede, as nominee of DTC. Certificate Owners will not be
Certificateholders as that term is used in the Pooling and Servicing Agreement.
Certificate Owners are only permitted to exercise the rights of
Certificateholders indirectly through Participants and DTC.
 
     While the Offered Certificates are outstanding (except under the
circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations (the "Rules"), DTC is required to
make book-entry transfers among Participants on whose behalf it acts with
respect to the Offered Certificates and is required to receive and transmit
distributions of principal of, and interest on, the Offered Certificates. Unless
and until Definitive Offered Certificates are issued, Certificate Owners who are
not Participants may transfer ownership of Offered Certificates only through
Participants by instructing such Participants to transfer Offered Certificates,
by book-entry transfer, through DTC for the account of the purchasers of such
Certificates, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of Offered Certificates will be executed through DTC and the accounts
of the respective Participants at DTC will be debited and credited.
 
     Offered Certificates will be issued in registered form to Certificate
Owners, or their nominees, rather than to DTC (such Certificates being referred
to herein as "Definitive Offered Certificates"), only if (i) DTC or the Seller
advises the Trustee in writing that DTC is no longer willing or able to
discharge properly its responsibilities as nominee and depository with respect
to the Offered Certificates and the Seller or the Trustee is unable to locate a
qualified successor, (ii) the Seller, at its sole option and with the consent of
the Trustee, elects to terminate the book-entry system through DTC or (iii)
after the occurrence of an Event of
                                      S-26
<PAGE>   89
 
Default, DTC, at the direction of Certificate Owners having a majority in
Percentage Interests of the Offered Certificates together, advises the Trustee
in writing that the continuation of a book-entry system through DTC (or a
successor thereto) to the exclusion of any physical certificates being issued to
Certificate Owners is no longer in the best interest of Certificate Owners. Upon
issuance of Definitive Offered Certificates to Certificate Owners, such
Certificates will be transferable directly (and not exclusively on a book-entry
basis) and registered holders will deal directly with the Trustee with respect
to transfers, notices and distributions.
 
     DTC has advised the Seller and the Trustee that, unless and until
Definitive Offered Certificates are issued, DTC will take any action permitted
to be taken by a Certificateholder under the Pooling and Servicing Agreement
only at the direction of one or more Participants to whose DTC account the
Offered Certificates are credited. DTC has advised the Seller that DTC will take
such action with respect to any Percentage Interests of the Offered Certificates
only at the direction of and on behalf of such Participants with respect to such
Percentage Interests of the Offered Certificates. DTC may take actions, at the
direction of the related Participants, with respect to some Offered Certificates
which conflict with actions taken with respect to other Offered Certificates.
 
     Issuance of the Offered Certificates in book-entry form rather than as
physical certificates may adversely affect the liquidity of the Offered
Certificates in the secondary market and the ability of Certificate Owners to
pledge them. In addition, since distributions on the Offered Certificates will
be made by the Trustee to DTC and DTC will credit such distributions to the
accounts to its Participants, which will further credit them to the accounts of
indirect participants of Certificate Owners, Certificate Owners may experience
delays in the receipt of such distributions.
 
LAST SCHEDULED DISTRIBUTION DATE
 
     The last scheduled Distribution Date for each Class of Offered Certificates
is as follows:
 
                                    [TABLE]
 
COLLECTION AND OTHER SERVICING PROCEDURES ON MORTGAGE LOANS
 
     The Master Servicer will make reasonable efforts to collect all payments
called for under the Mortgage Loans and will, consistent with the Pooling and
Servicing Agreement, follow such collection procedures as it follows from time
to time with respect to the home equity loans in its servicing portfolio
comparable to the Mortgage Loans. Consistent with the above, the Master Servicer
may in its discretion waive any late payment charge or any assumption or other
fee or charge that may be collected in the ordinary course of servicing the
Mortgage Loans.
 
     With respect to the Mortgage Loans, the Master Servicer may arrange with a
borrower a schedule for the payment of interest due and unpaid for a period,
provided that any such arrangement is consistent with the Master Servicer's
policies with respect to the home equity mortgage loans it owns or services.
 
HAZARD INSURANCE AND FLOOD INSURANCE
 
     The Master Servicer will cause to be maintained fire and hazard insurance
with extended coverage customary in the area where the Mortgaged Property is
located, in an amount which is at least equal to the lessor of (i) the
outstanding Loan Balance on the Mortgage Loan and any related senior lien(s),
(ii) the full insurable value of the premises securing the Mortgage Loan and
(iii) the minimum amount required to compensate for damage or loss on a
replacement cost basis in each case in an amount not less than such amount as is
necessary to avoid the application of any co-insurance clause contained in the
related hazard insurance policy. Generally, if the Mortgaged Property is in an
area identified in the Federal Register by the Flood Emergency Management Agency
as FLOOD ZONE "A", such flood insurance has been made available and the Master
Servicer determines that such insurance is necessary in accordance with accepted
second mortgage servicing practices of prudent lending institutions, the Master
Servicer will cause to be purchased a flood insurance policy with a generally
acceptable insurance carrier, in an amount representing
 
                                      S-27
<PAGE>   90
 
coverage not less than the least of (a) the outstanding Loan Balance of the
Mortgage Loan and the first lien, (b) the full insurable value of the Mortgaged
Property, or (c) the maximum amount of insurance available under the National
Flood Insurance Act of 1968, as amended. The Master Servicer will also maintain
on REO Property, to the extent such insurance is available, fire and hazard
insurance in the applicable amounts described above, liability insurance and, to
the extent required and available under the National Flood Insurance Act of
1968, as amended, and the Master Servicer determines that such insurance is
necessary in accordance with accepted second mortgage servicing practices of
prudent lending institutions, flood insurance in an amount equal to that
required above. Any amounts collected by the Master Servicer under any such
policies (other than amounts to be applied to the restoration or repair of the
Mortgaged Property, or to be released to the Mortgagor in accordance with
customary second mortgage servicing procedures) will be deposited in the
Collection Account, subject to retention by the Master Servicer to the extent
such amounts constitute servicing compensation or to withdrawal pursuant to the
Pooling and Servicing Agreement.
 
     In the event that the Master Servicer obtains and maintains a blanket
policy as provided in the Pooling and Servicing Agreement insuring against fire
and hazards of extended coverage on all of the Mortgage Loans, then, to the
extent such policy names the Master Servicer as loss payee and provides coverage
in an amount equal to the aggregate unpaid principal balance of the Mortgage
Loans without coinsurance, and otherwise complies with the requirements of the
first paragraph of this subsection, the Master Servicer will be deemed
conclusively to have satisfied its obligations with respect to fire and hazard
insurance coverage.
 
REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
     The Master Servicer will foreclose upon or otherwise comparably convert to
ownership Mortgaged Properties securing such of the Mortgage Loans as come into
default when, in accordance with applicable servicing procedures under the
Pooling and Servicing Agreement, no satisfactory arrangements can be made for
the collection of delinquent payments. In connection with such foreclosure or
other conversion, the Master Servicer will follow such practices as it deems
necessary or advisable and as are in keeping with its general subordinate
mortgage servicing activities, provided the Master Servicer will not be required
to expend its own funds in connection with foreclosure or other conversion,
correction of default on a related senior mortgage loan or restoration of any
property unless, in its sole judgment, such foreclosure, correction or
restoration will increase Net Liquidation Proceeds. The Master Servicer will be
reimbursed out of Liquidation Proceeds for advances of its own funds as
liquidation expenses before any Net Liquidation Proceeds are distributed to
Certificateholders.
 
EVIDENCE AS TO COMPLIANCE
 
     The Pooling and Servicing Agreement provides for delivery on or before the
last day of the fifth month following the end of the Master Servicer's fiscal
year, beginning in 199  , to the Trustee, the Depositor, the Certificate Insurer
and the Rating Agencies of an annual statement signed by an officer of the
Master Servicer to the effect that the Master Servicer has fulfilled its
material obligations under the Pooling and Servicing Agreement throughout the
preceding fiscal year, except as specified in such statement.
 
     On or before the last day of the      month following the end of the Master
Servicer's fiscal year, beginning in 199  , the Master Servicer will furnish a
report prepared by a firm of nationally recognized independent public
accountants (who may also render other services to the Master Servicer or the
Depositor) to the Trustee, the Depositor, the Certificate Insurer and the Rating
Agencies to the effect that such firm has examined certain documents and the
records relating to servicing of the Mortgage Loans under the Uniform Single
Audit Program for Mortgage Bankers and such firm's conclusion with respect
thereto.
 
     The Master Servicer's fiscal year is the calendar year.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER
 
     The Pooling and Servicing Agreement provides that the Master Servicer may
not resign from its obligations and duties thereunder, except in connection with
a permitted transfer of servicing, unless (i) such duties and obligations are no
longer permissible under applicable law or are in material conflict by reason of
                                      S-28
<PAGE>   91
 
applicable law with any other activities of a type and nature presently carried
on by it or its affiliate or (ii) upon the satisfaction of the following
conditions: (a) the Master Servicer has proposed a successor servicer to the
Trustee in writing and such proposed successor servicer is reasonably acceptable
to the Trustee; (b) the Rating Agencies have confirmed to the Trustee that the
appointment of such proposed successor servicer as the Master Servicer will not
result in the reduction or withdrawal of the then current rating of the
Certificates; and (c) such proposed successor servicer is reasonably acceptable
to the Certificate Insurer. No such resignation will become effective until the
Trustee or a successor servicer has assumed the Master Servicer's obligations
and duties under the Pooling and Servicing Agreement.
 
     The Master Servicer may perform any of its duties and obligations under the
Pooling and Servicing Agreement through one or more subservicers or delegates,
which may be affiliates of the Master Servicer. Notwithstanding any such
arrangement, the Master Servicer will remain liable and obligated to the Trustee
and the Certificateholders for the Master Servicer's duties and obligations
under the Pooling and Servicing Agreement, without any diminution of such duties
and obligations and as if the Master Servicer itself were performing such duties
and obligations.
 
     The Master Servicer may permit the placement of a subsequent senior
mortgage on any Mortgaged Property, provided that (a) the related Mortgage
succeeded to a first lien position after the Transfer Date for such Mortgage
Loan and, immediately following the placement of such senior lien, such Mortgage
is in a second lien position and the outstanding principal amount of the
mortgage loan secured by such senior lien is no greater than the outstanding
principal amount of the first mortgage loan existing as of such Transfer Date
and the recalculated combined loan-to-value ratio of the Mortgage Loan is not
greater than the Combined Loan-to-Value Ratio of such Mortgage Loan as of such
Transfer Date; or (b) the Mortgage relating to the Mortgage Loan was in a second
lien position as of the related Transfer Date; the new senior lien secures a
mortgage loan that refinances an existing first mortgage loan and the
outstanding principal amount of such refinanced mortgage loan is no greater than
the outstanding principal amount of the first mortgage loan existing as of such
Transfer Date and the recalculated combined loan-to-value ratio of such Mortgage
Loan is not greater than the Combined Loan-to-Value Ratio of such Mortgage Loan
as of such Transfer Date.
 
     In addition, the Master Servicer may agree to changes in the terms of a
Mortgage Loan, provided, however, that such changes (i) will not cause the Trust
Fund to fail to qualify as a REMIC and do not adversely affect the interests of
the Certificateholders or the Certificate Insurer, (ii) are consistent with
prudent business practices and (iii) do not change the Loan Rate of such
Mortgage Loan or extend the maturity date of such Mortgage Loans in excess of
one year. Any changes to the terms of a Mortgage Loan that would cause the Trust
Fund to fail to qualify as a REMIC, however, may be agreed to by the Master
Servicer, provided the Master Servicer has determined such changes are necessary
to avoid a prepayment of such Mortgage Loans, such changes are in accordance
with prudent business practices and the Master Servicer purchases such Mortgage
Loan in accordance with the terms of the Pooling and Servicing Agreement.
 
     The Pooling and Servicing Agreement provides that the Master Servicer will
indemnify the Trust Fund and the Trustee from and against any loss, liability,
expense, damage or injury suffered or sustained as a result of the Master
Servicer's actions or omissions in connection with the servicing and
administration of the Mortgage Loans which are not in accordance with the
provisions of the Pooling and Servicing Agreement. The Pooling and Servicing
Agreement provides that neither the Depositor nor the Master Servicer nor their
directors, officers, employees or agents will be under any other liability to
the Trust Fund, the Trustee, the Certificateholders or any other person for any
action taken or for refraining from taking any actin pursuant to the Pooling and
Servicing Agreement. However, neither the Depositor nor the Master Servicer will
be protected against any liability which would otherwise be imposed by reason of
willful misconduct, bad faith or gross negligence of the Depositor or the Master
Servicer in the performance of its duties under the Pooling and Servicing
Agreement or by reason of reckless disregard of its obligations thereunder. In
addition, the Pooling and Servicing Agreement provides that the Master Servicer
will not be under any obligation to appear in, prosecute or defend any legal
action which is not incidental to its servicing responsibilities under the
Pooling and Servicing Agreement. The Master Servicer may, in its sole
discretion, undertake any such legal action
 
                                      S-29
<PAGE>   92
 
which it may deem necessary or desirable with respect to the Pooling and
Servicing Agreement and the rights and duties of the parties thereto and the
interest of the Certificateholders thereunder.
 
     Any corporation into which the Master Servicer may be merged or
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Master Servicer shall be a party, or any corporation
succeeding to the business of the Master Servicer shall be the successor of the
Master Servicer hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything in the Pooling
and Servicing Agreement to the contrary notwithstanding.
 
EVENTS OF DEFAULT
 
     "Events of Default" will consist of (i)(A) any failure by the Master
Servicer to make any required Monthly Advance or (B) any other failure of the
Master Servicer to deposit in the Collection Account or Distribution Account any
deposit required to be made under the Pooling and Servicing Agreement, which
failure continues unremedied for two Business Days after the giving of written
notice of such failure to the Master Servicer by the Trustee, or to the Master
Servicer and the Trustee by the Certificate Insurer or any Certificateholder;
(ii) any failure by the Master Servicer duly to observe or perform in any
material respect any other of its covenants or agreements in the Pooling and
Servicing Agreement which, in each case, materially and adversely affects the
interests of the Certificateholders or the Certificate Insurer and continues
unremedied for 60 days after the giving of written notice of such failure to the
Master Servicer by the Trustee, or to the Master Servicer and the Trustee by the
Certificate Insurer or any Certificateholder; (iii) any failure by the Master
Servicer to make any required Servicing Advance, which failure continues
unremedied for a period of 30 days aft the giving of written notice of such
failure to the Master Servicer by the Trustee, or to the Master Servicer and the
Trustee by the Certificate Insurer or any Certificateholder; (iv) the loss and
delinquency experience with respect to the Mortgage Loans exceeds certain levels
in the Pooling and Servicing Agreement; or (v) certain events of insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings relating to the Master Servicer and certain actions by the Master
Servicer indicating insolvency, reorganization or inability to pay its
obligations (an "Insolvency Event").
 
     Upon the occurrence and continuation beyond the applicable grace period of
the event described in clause (i)(A) above, if any Monthly Advance is not made
by 4:00 P.M. New York Time on the second Business Day following written notice
to the Master Servicer of such event, the Trustee or a successor Servicer will
immediately assume the duties of the Master Servicer.
 
     Upon removal or resignation of the Master Servicer, the Trustee will be the
Successor Servicer (the "Successor Servicer"). The Trustee, as Successor
Servicer, will be obligated to make Monthly Advances and Servicing Advances and
certain other advances unless it determines reasonably and in good faith that
such advances would not be recoverable. If, however, the Trustee is unwilling or
unable to act as Successor Servicer, or if the majority of Certificateholders
(with the consent of the Certificate Insurer) or the Certificate Insurer so
requests, the Trustee may appoint, or petition a court of competent jurisdiction
to appoint, subject to the approval of the Certificate Insurer, any established
mortgage loan servicing institution acceptable to the Certificate Insurer having
a net worth of not less than $50,000,000 as the Successor Servicer in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Master Servicer.
 
     Notwithstanding the foregoing, a delay in or failure of the performance
referred to under clause (i) above for a period of ten Business Days or referred
to under clause (ii) above for a period of 30 Business Days, shall not
constitute an Event of Default if such delay or failure could not be prevented
by the exercise of reasonable diligence by the Master Servicer and such delays
or failure was caused by an act of God or other similar occurrence. Upon the
occurrence of any such event the Master Servicer shall not be relieved from
using its best efforts to perform its obligations in a timely manner in
accordance with the terms of the Pooling and Servicing Agreement and the Master
Servicer shall provide the Trustee, the Depositor, the Certificate Insurer and
the Certificateholders prompt notice of such failure or delay by it, together
with a description of its efforts to so perform its obligations.

RIGHTS UPON AN EVENT OF SERVICING TERMINATION
 
     So long as an Event of Default remains unremedied, either the Trustee, or
Certificateholders holding Certificates evidencing at least 51% of the
Percentage Interests in the Trust Fund, with the consent of the Certificate
Insurer, may terminate all of the rights and obligations of the Master Servicer
under the Pooling and Servicing Agreement and in and to the Mortgage Loans,
whereupon the Trustee will succeed to all the responsibilities, duties and
liabilities of the Master Servicer under the Pooling and Servicing Agreement and
will be entitled to similar compensation arrangements. In the event that the
Trustee would be obligated to succeed the Master Servicer but is unwilling 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 or other mortgage
loan or home equity loan servicer with all licenses and permits required to
perform its obligations under the Pooling and Servicing Agreement and having a
net worth of at least $50,000,000 and acceptable to the Certificate Insurer to
act as successor to the Master Servicer under the Pooling and Servicing
Agreement. Pending such appointment, the Trustee will be obligated to act in
such capacity unless prohibited by law. Such successor will be entitled to
receive the same compensation that the Master Servicer would otherwise have
received (or such lesser compensation as the Trustee and such successor may
agree). A receiver or conservator for the Master Servicer may be empowered to
prevent the termination and replacement of the Master Servicer if the only Event
of Default that has occurred is an Insolvency Event.
 
AMENDMENT
 
     The Pooling and Servicing Agreement may be amended from time to time by the
Seller, the Master Servicer, the Depositor and the Trustee and with the consent
of the Certificate Insurer, but without the consent of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with any other provisions of the Pooling and Servicing
Agreement, to add to the duties of the Depositor or the Master Servicer to
comply with any requirements imposed by the Internal Revenue Code or any
regulation thereunder, or to add or amend any provisions of the Pooling and
Servicing Agreement as required by the Rating Agencies in order to maintain or
improve any rating of the Offered Certificates (it being understood that, after
obtaining the ratings in effect on the Closing Date, neither the Depositor, the
Trustee, the Certificate Insurer not the Master Servicer is obligated to obtain,
maintain, or improve any such rating) or to add any other provisions with
respect to matters or questions arising under the Pooling and Servicing
Agreement which shall not be inconsistent with the provisions of the Pooling and
Servicing Agreement, provided that such action will not, as evidenced by an
opinion of counsel, materially and adversely affect the interests of any
Certificateholder or the Certificate Insurer; provided, that any such amendment
will not be deemed to materially and adversely affect the Certificateholders and
no such opinion will be required to be delivered if the person requesting such
amendment obtains a letter from the Rating Agencies stating that such amendment
would not result in a downgrading of the then current rating of the Offered
Certificates. The Pooling and Servicing Agreement may also be amended from time
to time by the Seller, the Master Servicer, the Depositor, and the Trustee, with
the consent of Certificateholders evidencing at least 51% of the Percentage
Interests of each Class affected thereby and the Certificate Insurer for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of the Pooling and Servicing Agreement or of modifying in any
manner the rights of the Certificateholders, provided that no such amendment
will (i) reduce in any manner the amount of, or delay the timing of, collections
of payments on the Certificates or distributions or payments under the Policy
which are required to be made on any Certificate without the consent of the
Certificateholder or (ii) reduce the aforesaid percentage required to consent to
any such amendment, without the consent of the holders of all Offered
Certificates then outstanding.
 
TERMINATION; PURCHASE OF MORTGAGE LOANS
 
     The Trust Fund will terminate on the Distribution Date following the later
of (A) payment in full of all amounts owing to the Certificate Insurer unless
the Certificate Insurer shall otherwise consent and (B) the earliest of (i) the
Distribution Date on which the Aggregate Class A Principal Balance has been
reduced to zero, (ii) the final payment or other liquidation of the last
Mortgage Loan in the Trust Fund, (iii) the optional purchase by the Master
Servicer of the Mortgage Loans, as described below and (iv) the Distribution
Date in
 
                                      S-31
<PAGE>   94
 
            , on which date the Certificate Insurance Policy will be available 
to pay the outstanding Aggregate Class A Principal Balance.
 
     Subject to provisions in the Pooling and Servicing Agreement concerning
adopting a plan of complete liquidation, the Master Servicer may, at its option,
terminate the Pooling and Servicing Agreement on any date on which the Aggregate
Class A Principal Balance is less than 5% of the Original Class A Certificate
Principal Balance, by purchasing, on the next succeeding Distribution Date, all
of the outstanding Mortgage Loans at a price equal to the sum of the outstanding
Aggregate Class A Principal Balance (subject to reduction as provided in the
Pooling and Servicing Agreement if the purchase price is based in part on the
appraised value of any REO Property included in the Trust Fund and such
appraised value is less than the Loan Balance of the related Mortgage Loan) and
accrued and unpaid interest thereon at the weighted average of the Loan Rates
through the end of the Collection Period preceding the final Distribution Date
together with all amounts due and owing to the Certificate Insurer.
 
     Any such purchase shall be accomplished by deposit into the Certificate
Account of the purchase price specified above.
 
                     DESCRIPTION OF THE PURCHASE AGREEMENT
 
     The Mortgage Loans to be transferred to the Trust Fund by the Depositor
will be purchased by the Depositor from First Union National Bank (the "Seller")
pursuant to the Mortgage Loan Purchase Agreement to be entered into between the
Depositor, as purchaser of the Mortgage Loans, and the Seller, as seller of the
Mortgage Loans (the "Mortgage Loan Purchase Agreement"). Under the Mortgage Loan
Purchase Agreement, the Seller will agree to transfer the Mortgage Loans to the
Depositor and the Subsequent Mortgage Loans to the Trust Fund. Pursuant to the
Pooling and Servicing Agreement, the Mortgage Loans will be immediately
transferred by the Depositor to the Trust Fund, and the Depositor will assign
its rights in, to and under the Mortgage Loan Purchase Agreement, to the Trust
Fund. The following summary describes certain terms of the form of the Mortgage
Loan Purchase Agreement and is qualified in its entirety by reference to the
form of Mortgage Loan Purchase Agreement.
 
TRANSFER OF MORTGAGE LOANS
 
     Pursuant to the Mortgage Loan Purchase Agreement, the Seller will transfer
and assign to the Depositor all of its right, title and interest in and to the
Mortgage Loans and the Related Documents. The purchase price of the Mortgage
Loans is a specified percentage of the face amount thereof as of the time of
transfer and is payable by the Depositor, as applicable, in cash.
 
  Representations and Warranties
 
     The Seller will represent and warrant to the Depositor that, among other
things, as of the Closing Date, it is duly organized and in good standing and
that it has the authority to consummate the transactions contemplated by the
Mortgage Loan Purchase Agreement.
 
     The Seller will also represent and warrant to the Depositor, that, among
other things, (a) the information with respect to the applicable Mortgage Loan
set forth in the schedule attached to the Mortgage Loan Purchase Agreement is
true and correct in all material respects, (b) immediately prior to the sale of
the Mortgage Loans to the Depositor, the Seller was the sole owner and holder of
the Mortgage Loans free and clear of any and all liens and security interests
and (c) each Mortgage Loan complied at the time of origination, in all material
respects, with applicable state and federal laws. The Seller will make similar
representations and warranties in the Pooling and Servicing Agreement. The
Seller will also represent and warrant to the Depositor, that, among other
things, as of the Closing Date, the Mortgage Loan Purchase Agreement constitutes
a legal, valid and binding obligation of the Seller. The Seller will covenant to
sell the Subsequent Mortgage Loans to the Trust Fund in accordance with the
terms of the Pooling and Servicing Agreement. In the event of a breach of any
such representations and warranties which has a material adverse effect on the
interests of the Certificateholders or the Certificate Insurer, the Seller will
repurchase or
 
                                      S-32
<PAGE>   95
 
substitute for the Mortgage Loans as described herein under "Description of the
Certificates -- Assignment of Mortgage Loans."
 
     The Seller has also agreed to indemnify the Depositor and the Trust Fund
from and against certain losses, liabilities and expenses (including reasonable
attorneys' fees) suffered or sustained pursuant to the Mortgage Loan Purchase
Agreement.
 
ASSIGNMENT TO THE TRUST FUND
 
     The Seller expressly acknowledges and consents to the Depositor's transfer
of its rights relating to the Mortgage Loans under the Mortgage Loan Purchase
Agreement to the Trust Fund. The Seller also agrees to perform its obligations
under the Mortgage Loan Purchase Agreement for the benefit of the Trust Fund.
 
TERMINATION
 
     The Mortgage Loan Purchase Agreement will terminate upon the termination of
the Trust Fund.
 
                                  THE TRUSTEE
 
                    , a                corporation located at                .
 
     The Trustee will at all times be required to be a corporation incorporated
and doing business under the laws of the United States of America or any state
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $50,000,000, subject to supervision by federal
or state authority and if Moody's is a Rating Agency, having (or in the case of
a corporation including a bank holding company system, the related bank holding
company shall have) a rating with respect to its long-term unsecured debt
obligations of at least Baa1 (or such lower rating as Moody's may from time to
time agree). If at any time the Trustee shall cease to be eligible in accordance
with the provisions described in this paragraph, it will be required to resign
immediately in the manner described below.
 
     No resignation or removal of the Trustee and no appointment of a successor
trustee shall become effective until the acceptance of appointment by a
successor trustee.
 
     In addition to being required to resign in the circumstances described
above, the Trustee, or any trustee or trustees hereafter appointed, may resign
at any time in the manner set forth in the Pooling and Servicing Agreement. Upon
receiving notice of resignation, the Seller is required promptly to appoint a
successor trustee or trustees acceptable to the Certificate Insurer and the
Master Servicer meeting the eligibility requirements in the manner to be set
forth in the Pooling and Servicing Agreement. If no successor trustee shall have
been appointed and have accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.
 
     If the Trustee shall cease to be eligible and fail to resign after written
request by the Seller or Certificate Insurer, or if the Trustee is legally
unable to act or becomes insolvent or a tax is imposed or threatened with
respect to the Trust, the Seller or the Certificate Insurer may remove the
Trustee. The Seller is required to promptly appoint a successor trustee
acceptable to the Certificate Insurer.
 
     The Seller will be required to give notice of any removal of the Trustee to
the Owners, which notice will be required to include the name of the successor
trustee and the address of its corporate trust office. The Seller also will be
required to give notice to the Owners of the acceptance by a successor of its
appointment.

          THE CERTIFICATE INSURER AND THE CERTIFICATE INSURANCE POLICY
 
CERTIFICATE INSURER
 
     The following information with respect to        (the "Certificate
Insurer") has been furnished by the Certificate Insurer, and neither First Union
National Bank nor any Affiliate thereof has made any independent investigation
of such information.
 
     [Insert information supplied by Certificate Insurer]
 
CERTIFICATE INSURANCE POLICY
 
     On or before the Closing Date, the Certificate Insurance Policy (the
"Certificate Insurance Policy") or (the "Policy") will be issued by the
Certificate Insurer pursuant to the provisions of the Insurance Agreement (the
"Insurance Agreement") dated as of             , 199  among the Seller, the
Master Servicer, the Trustee, the Depositor and the Certificate Insurer.
 
     [The Policy will unconditionally and irrevocably guarantee the timely
payment of interest due and the ultimate payment of principal on the Class A
Certificates. On each Distribution Date, a draw will be made on the Policy equal
to the sum of (a) the amount by which the sum of interest accrued with respect
to each Class of Class A Certificates, the applicable Certificate Rate on the
related outstanding Class A Principal Balance exceeds the amount on deposit in
the Distribution Account available to be distributed therefor on such
Distribution Date and (b) the amount (each, a "Class A Guaranteed Principal
Distribution Amount"), if any, by which the Aggregate Class A Principal Balance
exceeds the Pool Balance at the end of the previous month (after giving effect
to all amounts distributable and allocable to principal on the related Class A
Certificates on such Distribution Date). In addition, the Policy will guarantee
the payment in full of the Aggregate Class A Principal Balance on the
Distribution Date in        (after giving effect to all other amounts
distributable and allocable to principal on such Classes on such Distribution
Date).]
 
     Any Class A Guaranteed Principal Distribution Amount on any Distribution
Date will be distributed to the Class or Classes of Class A Certificates then
entitled to distributions of principal.
 
     [In addition, the Policy will provide for payment of the amount of any
distributions in respect of principal or interest previously paid to a Class A
Certificateholder that are subsequently recovered from such Certificateholder
pursuant to a final, nonappealable order of a court of competent jurisdiction
under the United States Bankruptcy Code. Any such payments would be made under
the Policy on the second business day following receipt by the Certificate
Insurer of a certified copy of the order, assignment to the Certificate Insurer
of such Certificateholder's rights and appointment of the Certificate Insurer as
such Certificateholder's agent. No such Certificateholder shall be entitled to
reimbursement for any payment avoided as a preference as to which the
Certificate Insurer has made a payment under the Policy.]
 
     The Certificate Insurer's obligations under the Policy will be discharged
to the extent that funds are received by the Trustee for distribution to the
Class A Certificateholders, whether or not such funds are properly distributed
by the Trustee. For purposes of the Policy, Certificateholder does not include
the Trust Fund, the Master Servicer, the Seller or the Depositor. The Policy
does not guarantee any specified rate of prepayments of principal of the
Mortgage Loans or any specified return. The Policy is non-cancelable.
 
     In the absence of payments under the Policy, Certificateholders will
directly bear the credit and other risks associated with their undivided
interest in the Trust Fund.
 
                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
GENERAL -- LIEN PRIORITY
 
     The Mortgage Loans will be secured by either deeds of trust, deeds to
secure debt or mortgages (each, a "Security Instrument"), depending upon the
prevailing practice in the state in which the Mortgaged Property is located. A
mortgage creates a lien upon the real property described in the mortgage. It is
not prior to the lien
                                      S-34
<PAGE>   97
 
for real estate taxes and assessments. Priority between mortgages depends on
their terms and generally on the order of recording with a state or county
office. There are two parties to a mortgage, the mortgagor, who is the
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. A deed
of trust formally has three parties: the homeowner, called the grantor (similar
to a mortgagor), a lender (similar to the mortgagee), called the beneficiary,
and a third-party grantee, called the trustee. Under a deed of trust, the
grantor grants the property, irrevocably until the debt is paid, "in trust, with
the 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, the express provisions of the deed of trust or the
mortgage, and, in some cases under a deed of trust, the direction of the
beneficiary.
 
     The security property encumbered by a Security Instrument also may be
encumbered by other liens. The priority of the liens is important because, among
other things, the foreclosure of a senior lien will extinguish a junior lien,
and because the holder of a senior lien generally will have a right to receive
insurance, condemnation or other proceeds before the holder of a junior lien.
See "-- Junior Liens; Rights of Senior Lienholders" below.
 
     Priority between Security Instruments of record generally depends in the
first instance on the order of filing with the appropriate government records
office. Priority also may be affected by the express terms of the Security
Instrument or other documents, such as subordination agreements.
 
     Although priority among liens on the same property generally depends in the
first instance on the order of filing there are a number of ways in which a lien
that is a senior lien when it is filed can become subordinate to a lien filed at
a later date. A lienholder's lien under Security Instrument is not prior to any
liens for real estate taxes and assessments, certain federal liens (including
certain federal criminal liens, environmental liens and tax liens), certain
mechanics and materialmen's liens, and other liens given priority by applicable
law. In addition, in certain states, the priority of a mechanics lien may relate
back to the date construction of the property began, even though that date
precedes the date on which the mechanics lien is actually filed, and in
Virginia, a mechanics lien is given a superpriority over subsequent liens.
Therefore, since a title report or title policy only is accurate as of the date
it is issued, it provides no assurance that a Security Instrument will retain
perpetually the lien priority it had when it was filed. The Security Instruments
securing the Mortgage Loans include a requirement that each borrower maintain
the lien priority of each Security Instrument.
 
FORECLOSURE
 
     If a borrower defaults under a loan secured by a Security Instrument the
lender generally may bring suit against the borrower. The lender generally also
may attempt to collect the loan by causing the Security Instrument to be
enforced against the property it encumbers.
 
     Foreclosure of a deed of trust or a deed to secure debt is generally
accomplished by a non-judicial trustee's sale under a specific provision in the
deed of trust or security deed which authorizes the sale of the property to a
third party upon any default by the borrower under the terms of the note, deed
of trust or security deed. In some states, the trustee must record a notice of
default and send a copy to the borrower-grantor and to any person who has
recorded a request for a copy of a notice of default and notice of sale. In
addition, the trustee must provide notice in some states to any other individual
having an interest in the real property, including any junior lienholders. The
borrower, 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 obligations.
Generally, state laws require that a through advertisements and other means,
notice of the sale be given to all parties having an interest in the real
property; in certain states such notice may include posting a copy of the notice
on the property.
 
     Foreclosure of a mortgage is generally accomplished by judicial action. The
action is initiated by the service of legal pleadings upon all parties having an
interest in the real property. Delays in completion of the foreclosure may
occasionally result from difficulties in locating necessary parties defendant.
Judicial foreclosure proceedings are sometimes not contested by any of the
parties defendant.
 
                                      S-35
<PAGE>   98
 
     In the case of foreclosure under a Security Instrument, the sale by the
referee or other designated officer or by the trustee, as applicable, is a
public sale. It is not uncommon for the lender to purchase the property at
foreclosure. In many cases where the lender purchases at foreclosure, it usually
purchases the property for an amount equal to the principal amount of the
Security Instrument, accrued and unpaid interest and the expense of foreclosure.
 
     Because (i) there may be no equity in the security property, (ii) there is
a requirement that the purchaser pay to bid for the property in cash or by
cashiers check, (iii) a potential buyer at the sale may find it difficult to
determine the exact status of title and other facts about the security property
and (iv) the physical condition of the security property may have deteriorated,
it generally is more common for the lender, rather than an unrelated third
party, to purchase the security property at foreclosure. The lender (or other
purchaser at the trustee's sale) will be subject to the burdens of ownership,
including the obligations to service any senior Security Instrument, to obtain
hazard insurance and to make such repairs at its own expense as are necessary to
render the security property suitable for resale. The lender commonly will
attempt to resell the security property and obtain the services of a real estate
broker and agree to pay the broker a commission in connection with the resale.
Depending upon market conditions, the ultimate proceeds of the resale of the
security property may not be high enough to equal the lender's investment.
Property securing a Mortgage Loan that is acquired through a trustee's sale or
judicial foreclosure must be sold by the Trustee within two years after the date
on which it is acquired, in order to satisfy certain federal income tax
requirements.
 
     The proceeds received from the sale generally are applied first to the
costs, fees and expenses of sale and then in satisfaction of the indebtedness
secured by the Security Instrument under which the sale was conducted. Any
remaining proceeds generally are payable to the holders of junior Security
Instruments and other liens and claims in order of their priority. Any balance
remaining generally is payable to the grantor or mortgagor. Following the sale,
if there are insufficient proceeds to repay the secured debt, the beneficiary
under the foreclosed lien generally may obtain a deficiency judgment against the
grantor or mortgagor. See "-- Anti-Deficiency Legislation; Bankruptcy and
Consumer Protection Legislation" below.
 
     Some courts have been faced with the issue of whether federal or state
constitutional due process requires that borrowers under deeds of trust receive
notices in addition to the statutorily prescribed minimum. For the most part,
the courts in these cases have upheld the notice provisions and procedures
described above.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the borrower and foreclosed junior lienors are given a statutory
period in which to redeem the property from the foreclosure sale. In some
states, redemption may occur only upon payment of the entire principal balance
of the loan, accrued interest and expenses of foreclosure. In other states,
redemption may be authorized if the former borrower pays only a portion of the
sums due. The effect of a statutory right of redemption is to diminish the
ability of the lender to sell the foreclosed property. The rights 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; BANKRUPTCY AND CONSUMER PROTECTION LEGISLATION
 
     Certain states have imposed statutory prohibitions which limit the remedies
of a beneficiary under a deed of trust or security deed or a mortgagee under a
mortgage. In some states, statutes limit the right of the beneficiary or
mortgagee to obtain, or prohibit the beneficiary or mortgagee from obtaining a
deficiency judgment against the borrower following foreclosure or sale under a
deed of trust. A deficiency judgment would be a personal judgment against the
former borrower equal in most cases to the difference between the net amount
received upon the public sale of the real property and the amount due to the
lender. Other statutes require the beneficiary or mortgagee to exhaust the
security afforded under a Security Instrument by foreclosure in an attempt to
satisfy the full debt before bringing a personal action against the borrower.
Finally, other statutory provisions limit any deficiency judgment against the
former borrower following a judicial sale
 
                                      S-36
<PAGE>   99
 
to the excess of the outstanding debt over the fair market value of the property
at the time of the public sale. The purpose of these statutes is generally to
prevent a beneficiary or a mortgagee from obtaining a large deficiency judgment
against the former borrower as a result of low or no bids at the judicial sale.
 
     In addition to laws limiting or prohibiting deficiency judgments, 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 the sale of the collateral and/or
enforce a deficiency judgment. For example, with respect to federal bankruptcy
law, a court with federal bankruptcy jurisdiction may permit a debtor through
his or her Chapter 11 or Chapter 13 rehabilitative plan to cure a monetary
default in respect of a mortgage loan on such debtor's residence by paying
arrearages within a reasonable time period and reinstating the original mortgage
loan payment schedule even though the lender accelerated the mortgage loan and
final judgment of foreclosure had been entered in state court (provided no sale
of the residence had yet occurred) prior to the filing of the debtor's petition.
Some courts with federal bankruptcy jurisdiction have approved plans, based on
the particular facts of the reorganization case, that effected the curing of a
mortgage loan default by paying arrearages over a number of years.
 
     Courts with federal bankruptcy jurisdiction have also indicated that the
terms of a mortgage loan secured by property of the debtor may be modified.
These courts have suggested that such modifications may include reducing the
amount of each monthly payment, changing the rate of interest, altering the
repayment schedule, and reducing the lender's security interest to the value of
the residence, thus leaving the lender as a general unsecured creditor for the
difference between the value of the residence and the outstanding balance of the
loan.
 
     The Code provides priority to certain tax liens over the lien of the
mortgage. In addition, substantive requirements are imposed upon mortgage
lenders in connection with the origination and the servicing of mortgage loans
by numerous federal and some state consumer protection laws. 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 such loans.
 
JUNIOR LIENS; RIGHTS OF SENIOR LIENHOLDERS
 
     The rights of the Trust Fund (and therefore the Owners) as beneficiary
under a junior deed of trust or security deed or as mortgagee under a junior
mortgage are subordinate to those of the mortgagee or beneficiary under the
senior Security Instrument, including the prior rights of the senior mortgagee
or beneficiary to receive hazard insurance and condemnation proceeds and to
cause the property securing the second mortgage loan to be sold upon default of
the mortgagor or grantor, thereby extinguishing the junior mortgagee's or junior
beneficiary's lien unless the holders thereof assert their subordinate interest
in a property in foreclosure litigation or satisfy the defaulted senior loan. As
discussed more fully below, in many states a junior mortgagee or beneficiary may
satisfy a defaulted senior loan in full, or may cure such default and bring the
senior loan current, in either event adding the amounts expended to the balance
due on the junior loan.
 
     The standard form of Security Instrument used by most institutional lenders
confers on the mortgagee or beneficiary the right both to receive all proceeds
collected under any hazard insurance policy and all awards made in connection
with any condemnation proceedings, and to apply such proceeds and awards to any
indebtedness secured by the Security Instrument in such order as the mortgagee
or beneficiary may determine. Thus, in the event improvements on the property
are damaged or destroyed by fire or other casualty, or in the event the property
is taken by condemnation, the mortgagee or beneficiary under the underlying
first Security Instrument will have the prior right to collect any insurance
proceeds payable under a hazard insurance policy and any award of damages in
connection with the condemnation and to apply the same to the indebtedness
secured by the first priority Security Instrument. Proceeds in excess of the
amount of first Security Instrument indebtedness will, in most cases, be applied
to the indebtedness of a junior Security Instrument.
 
                                      S-37
<PAGE>   100
 
     The form of Security Instrument by most institutional lenders typically
contains a "Future Advances" clause, which provides, in essence, that additional
amounts advanced to or on behalf of the mortgagor or grantor by the mortgagee or
beneficiary are to be secured by the Security Instrument. While such a clause is
valid under the laws of most states, the priority of any advance made under the
clause depends, in some states, on whether the advance was an "Obligatory" or
"Optional" advance. If the mortgagee or beneficiary is obligated to advance the
additional amounts, the advance is entitled to receive the same priority as
amounts initially made under the Security Instrument, notwithstanding that there
may be intervening junior mortgages or deeds of trust and other liens between
the date of recording of the Security Instrument and the date of the future
advance, and notwithstanding that the mortgagee or beneficiary had actual
knowledge of such intervening junior mortgages or deeds of trust and other liens
at the time of the advance. Where the mortgagee or beneficiary is not obligated
to advance the additional amounts and, in certain states, has actual knowledge
of the intervening junior Security Instrument and other liens, the advance will
be subordinate to such intervening junior Security Instrument and other liens.
Priority of advances under the clause rests, in many other states, on state
statutes giving priority to all advances made under the loan agreement to a
"Credit Limit" amount stated in the recorded mortgage.
 
     Another provision typically found in the form of the Security Instrument
used by most institutional lenders obligates the mortgagor or grantor to pay
before delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which appear prior to the
Security Instrument, to provide and maintain fire insurance on the property, to
maintain and repair the property and not to commit or permit any waste thereof,
and to appear in and defend any action or proceeding purporting to affect the
property or the rights of the mortgagee or beneficiary under the Security
Instrument. Upon a failure of the mortgagor or grantor to perform any of these
obligations, the mortgagee or beneficiary is given the right under the Security
Instrument to perform the obligation itself, at its election, with the mortgagor
or grantor agreeing to reimburse the mortgagee or beneficiary for any sums
expended by the mortgagee or beneficiary on behalf of the grantor. All sums so
expended by the mortgagee or beneficiary become part of the indebtedness secured
by the Security Instrument.
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
     Upon foreclosure, courts have imposed general equitable principles. These
equitable principles are generally designed to relieve the borrower from the
legal effect of his defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have substituted their judgment for
the lender's judgment and have required that lenders reinstate loans or recast
payment schedules in order to accommodate borrowers who are suffering from
temporary financial disability. In other cases, courts have limited the right of
the lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower failing adequately to maintain the property or
the borrower executing a second Security Instrument affecting the property.
Finally, some courts have been faced with the issue of whether or not federal or
state constitutional provisions reflecting due process concerns for adequate
notice require that borrowers under deeds of trust or mortgages receive notices
in addition to the statutory prescribed minimum. For the most part, these cases
have upheld the notice provisions as being reasonable or have found that the
sale by a trustee under a deed of trust, or under a mortgage having a power of
sale, does not involve sufficient state action to afford constitutional
protections to the borrower.
 
     To the extent that the Mortgage Loans contain due-on-sale clauses, the
Master Servicer may declare the unpaid amounts thereof due and payable upon the
sale or transfer of all or any part of the underlying Property without the
Master Servicer's prior written consent. The enforceability of due-on-sale
clauses in certain situations has been restricted by the laws of some states.
However, federal law now preempts state statutory and case law which prohibits
enforcement of due-on-sale clauses and permits the enforcement of due-on-sale
clauses, subject to certain exceptions. The Master Servicer intends to enforce
the due-on-sale clause contained in any Mortgage Loan to the extent that it has
knowledge of the conveyance or proposed transfer of the
 
                                      S-38
<PAGE>   101
 
underlying Mortgaged Property and it believes that it is entitled to do so under
applicable federal laws and regulations.
 
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, 1990. The statute authorized any
state to reimpose interest rate limits by adopting, before April 1, 1983, a law
or constitutional provision which expressly rejects application of the federal
law. In addition, even where Title V is not so rejected, any state is authorized
by 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. In the
Pooling and Servicing Agreement, the Seller will represent and warrant that each
Mortgage Loan was originated in compliance with applicable state law in all
material respects.
 
ENVIRONMENTAL LEGISLATION
 
     Certain states impose a statutory lien for certain 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 Security Instrument. 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 security property at a
foreclosure sale may be liable for the costs of cleaning up a contaminated site.
Although such costs could be substantial, it is unclear whether they would be
imposed on a secured lender (such as the Trust Fund) without the presence of
certain other facts.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940
 
     Under the Soldiers' and Sailors' Civil Relief Act of 1940, members of all
branches of the military on active duty, including draftees and reservists in
military service, (i) are entitled to have interest rates reduced and capped at
6.00% per annum, on obligations (including mortgage loans) incurred prior to the
commencement of military service for the duration of military service, (ii) may
be entitled to a stay of proceedings on any kind of foreclosure or repossession
action in the case of defaults on such obligations entered into prior to
military service and (iii) may have the maturity of such obligations incurred
prior to military service extended, the payments lowered and the payment
schedule readjusted for a period of time after the completion of military
service. However, the benefits of (i), (ii), or (iii) above are subject to
challenge by creditors and if, in the opinion of the court, the ability of a
person to comply with such obligations is not materially impaired by military
service, the court may apply equitable principles accordingly.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a general discussion of the material anticipated federal
income tax consequences of the purchase, ownership and disposition of the
Offered Certificates prepared by Moore & Van Allen, PLLC, counsel to the Seller
("Tax Counsel"). The discussion is based upon the Internal Revenue Code of 1986,
as amended (the "Code"), existing and proposed Treasury regulations thereunder,
including regulations (the "REMIC Regulations" and the "OID Regulations")
promulgated under the real estate mortgage investment conduit and original issue
discount provisions of the Code, published rulings and court decisions, any of
which is subject to change, possibly with retroactive effect. The discussion
does not purport to deal with all federal tax consequences applicable to all
categories of investors, some of whom may be subject to special rules. Investors
should consult their tax advisors in determining the particular federal, state,
local and any other tax consequences to them of the purchase, ownership and
disposition of the Offered Certificates.
 
                                      S-39
<PAGE>   102
 
REMIC ELECTION
 
     Pursuant to the Pooling and Servicing Agreement, the Trustee will elect to
treat a portion of the Trust Fund as one or more REMICs for federal income tax
purposes. Qualification as a REMIC requires ongoing compliance with certain
conditions. Tax Counsel will advise the Seller that, in its opinion, for federal
income tax purposes, assuming (i) the REMIC elections are properly made and (ii)
the Pooling and Servicing Agreement is complied with, a portion of the Trust
Fund will be treated as a REMIC, the Class A Certificates and the Class B
Certificates will be treated as regular interests in the REMIC and the Class R
Certificate will be treated as the sole residual interest in the REMIC. The
Class A Certificates and the Class B Certificates offered hereby are referred to
herein as the "Regular Certificates."
 
     The REMIC generally will not be subject to federal income tax except with
respect to any income from prohibited transactions, any "Net Income from
Foreclosure Property", and certain contributions, if any, to the Trust Fund
after the Startup Day (see "-- Taxes That May be Imposed on the Trust Fund"
below).
 
CERTAIN SPECIAL RULES RELATING TO THE REGULAR CERTIFICATES
 
     Regular Certificates held by a thrift institution taxed as a "domestic
building and loan association" will constitute assets described in Section
7701(a)(19)(C) of the Code and Regular Certificates held by a real estate
investment trust will constitute "real estate assets" within the meaning of
Section 856(c)(4)(A) of the Code. If less than 95% of the assets comprising a
REMIC constitute assets qualifying under any of the foregoing sections of the
Code, then the Regular Certificates will be qualifying assets under such
sections only to the extent that the assets comprising the REMIC are qualifying
assets. Owners of Regular Certificates should be aware that Regular Certificates
held by certain financial institutions will be "evidences of indebtedness"
within the meaning of Section 582(c) of the Code. Interest on the Regular
Certificates will be interest described in Section 856(c)(3)(B) of the Code to
the extent that the Regular Certificates are treated as "real estate assets"
within the meaning of Section 856(c)(5)(A) of the Code. Regular Certificates
will represent "qualified mortgages," within the meaning of Section 860G(a)(3)
of the Code, for other REMICs and "permitted assets," within the meaning of
Section 860L(c) of the Code, for financial asset securitization investment
trusts.
 
INTEREST; ORIGINAL ISSUE DISCOUNT AND PREMIUM
 
     For federal income tax purposes, regular interests in a REMIC generally are
treated as debt instruments issued by the REMIC, and not as ownership interests
in the REMIC or its assets. Owners of Regular Certificates, including those that
otherwise report income under the cash method of accounting, will be required to
include in income all interest and original issue discount, if any, on such
Certificates in accordance with accrual method of accounting.
 
     The [Class           ] Certificates will be issued with "original issue
discount" ("OID") for federal income tax purposes. The prepayment assumption
that will be used in determining the rate of accrual of OID, and market discount
and premium, if any, for federal income tax purposes is [     %] of the SPA. No
representation is made that the Mortgage Loans will prepay at any given
percentage of the SPA. For federal income tax purposes, owners of Regular
Certificates issued with OID must include in gross income the original issue
discount on such Certificates on an economic accrual basis generally in advance
of the receipt of the cash attributable to such income. Information with respect
to the accrual of OID on Regular Certificates will be reported annually (or more
often, if required) by the Trust Administrator to the Internal Revenue Service
(the "Service") and will also be provided, at such times and in the manner
required by the Service, to owners of such Regular Certificates, and relevant
brokers and middlemen. See "Certain Federal Income Tax Consequences -- REMIC
Certificates -- Regular Certificates" in the Prospectus for a more detailed
discussion of the computation of OID on certain Regular Certificates.
 
     Under current law, it is not entirely clear the manner in which income
should be accrued on Regular Certificates, such as the Class 1A-WIO
Certificates, the payments on which consist solely of interest on a notional
principal amount. The most reasonable method is to treat all of the income
derived from such Certificates as constituting OID. This is the position that
will be taken by the REMIC. Among other
                                      S-40
<PAGE>   103
 
possibilities, the Service could assert that this Class of Certificates should
instead be taxable under certain Treasury regulation provisions governing debt
instruments issued with contingent payments.
 
     If actual prepayments on the Mortgage Loans were to differ significantly
from the [     %] SPA, the calculation of OID for certain Classes of Offered
Certificates, such as the [Class        ] Certificates, might produce a negative
amount of OID for certain accrual periods ("Negative OID"). In such event,
Certificateholders of these Classes of Certificates likely would not be entitled
to a deduction for the Negative OID amount, but instead will be required to
carry such amount forward as an offset to OID, if any, accruing in future
periods.
 
     The [Class        ] Certificates will be issued at a premium for federal
income tax purposes. A Holder of such a Certificate may elect to amortize such
premium generally under a constant yield method over the life of the
Certificate, as an offset to interest income. Any such election may affect the
tax treatment of other debt instruments owned by the Holder, however, and
accordingly, Holders should consult their tax advisors regarding the possibility
and consequences of making such an election. See "Certain Federal Income Tax
Consequences -- REMIC Certificates -- Regular Certificates -- Premium" in the
Prospectus.
 
     For further information regarding the federal income tax consequences of
investing in the Certificates, see "Certain Federal Income Tax
Consequences -- REMIC Certificates -- Regular Certificates" in the Prospectus.
 
SPECIAL TAX CONSIDERATIONS APPLICABLE TO THE CLASS R CERTIFICATE
 
     The Class R Certificateholder likely will be required to report an amount
of taxable income (including excess inclusions, which generally may not be
offset with any other losses of the Holder) in earlier accrual periods in
respect of their Class R Certificate significantly in excess of cash
distributions received on such Certificates for such periods. In addition, the
inclusion of taxable income in respect of the ownership of Class R Certificate
during earlier accrual periods and the deferral of corresponding tax losses or
deductions on these Certificates until later accrual periods or until the
ultimate sale or disposition of a Class R Certificate (or possibly even later
pursuant to the application of the "wash sale" rules under Section 1091 of the
Code) may cause the present value of a Class R Certificateholder's resulting tax
liabilities attributable to the ownership of a Class R Certificate to
substantially exceed the sum of any tax benefits and any cash distributions on
the Class R Certificate over its life.
 
     Moreover, as previously discussed with respect to the [Class
               ] Certificates, and in the Prospectus, the rules for accrual of
original issue discount with respect to certain Certificates are subject to
significant complexity and uncertainty. Because original issue discount on
applicable Certificates will be deducted in determining REMIC taxable income,
any changes required by the Service in the application of the OID rules to such
Certificates may significantly affect the timing of the REMIC's original issue
discount deductions and therefore the amount of taxable income allocable to the
Holder of the Class R Certificate.
 
     The REMIC Regulations impose various restrictions on the transfer and
acquisition of residual interests, such as the Class R Certificate, including
prohibitions on the transfer of "non-economic" residual interests to certain
non-United States persons. The Pooling and Servicing Agreement generally
prohibits the transfer of the Class R Certificate to non-United States persons
(as defined therein). Moreover, the REMIC Regulations provide that a transfer to
a United States person of a "noneconomic" residual interest will be disregarded
for all federal income tax purposes, and the purported transferor of the
"noneconomic" residual interest will continue to remain liable for any taxes due
with respect to the income on such residual interest, unless no significant
purpose of the transfer was to impede the assessment or collection of tax. It is
expected that the Class R Certificate will constitute a noneconomic residual
interest at all times. Accordingly, any purported transfer of a Class R
Certificate to a United States person will not be given effect for federal
income tax purposes, and the purported transferor will remain liable for any
taxes due with respect to the income on the Class R Certificate, unless no
significant purpose of such a transfer is to impede the assessment or collection
of tax. See also "Certain Federal Income Tax Consequences -- REMIC
Certificates -- Tax-Related Restrictions on Transfers of Residual Certificates"

     The Master Servicing Fees, Subservicing Fees, Trust Administration Fees,
and Trustee Fees, and other administrative expenses properly allocable to a
REMIC will be allocated for federal income tax information reporting purposes
entirely to the Class R Certificate. An individual, trust or estate that holds
(whether directly or indirectly through certain pass-through entities) an
interest in a Class R Certificate may be subject to certain limitations on the
deductibility of these fees and expenses in computing such Certificateholder's
regular tax liability. Moreover, such fees or expenses will not be deductible to
any extent in computing such Certificateholder's alternative minimum tax
liability. See "Certain Federal Income Tax Consequences -- Residual
Certificates" and "-- Taxation of the REMIC -- Net Losses of the REMIC" in the
Prospectus.
 
     A purchaser of the Class R Certificate is urged to consult its tax advisors
as to the economic, tax and other legal consequences of an investment in the
Class R Certificate.
 
     For further information regarding the federal income tax consequences of
investing in the Class R Certificate, see "Certain Federal Income Tax
Consequences -- Residual Certificates" and "-- Taxation of the REMIC" in the

consequences of investing in the Certificate, see "Certain Federal Income Tax
Consequences' in the Prospectus.

     The foregoing does not address any aspect of state, local, foreign or other
tax consequences to an investor arising from the purchase, ownership or
disposition of a Certificate, and the Depositor makes no representation in this
regard. All investors should consult their tax advisors regarding the particular
federal, state, local, foreign or other tax consequences tot hem from the
purchase, ownership and disposition of the Certificates.

purchase, ownership or disposition of the Offered Certificates under the tax
laws of any state. Investors considering an investment in the Certificates
should consult their own tax advisors regarding such tax consequences.

                              ERISA CONSIDERATIONS
 
     Title I of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") imposes certain requirements on certain employee benefit plans and
arrangements, and upon collective investment funds and separate accounts in
which such plans or arrangements are invested, and on those persons who are
fiduciaries with respect to such benefit plans. In accordance with ERISA's
general fiduciary standards, before investing in a Class A Certificate a benefit
plan fiduciary should determine whether such an investment is permitted under
the governing benefit plan instruments and is appropriate for the benefit plan
in view of its overall investment policy and the composition and diversification
of its portfolio.
 
     In addition, benefit plans subject to Title I of ERISA and individual
retirement accounts or certain types of Keogh plans not subject to Title I of
ERISA but subject to Section 4975 of the Internal Revenue Code of 1986, as
amended (the "Code") (each a "Plan") are prohibited from engaging in a broad
range of transactions relating to the assets of the Plan when persons having
certain specified relationships to a Plan (called "parties in interest" in ERISA
and "disqualified persons" in the Code) are involved. Such transactions are
treated as "prohibited transactions" under Sections 406 and/or 407 of ERISA, and
excise taxes are imposed upon such persons by Section 4975 of the Code. The
Depositor, the Master Servicer, the Sub-servicers, the Trustee, the Underwriter,
the Certificate Insurer and certain of their affiliates might be considered
"parties in interest" or "disqualified persons" with respect to a Plan. If so,
the acquisition or holding or transfer of Class A Certificates by or on behalf
of such Plan could be considered to give rise to a "prohibited transaction"
within the meaning of ERISA and/or the Code unless an exemption is available. A
 
                                      S-42
<PAGE>   105
 
Plan fiduciary considering an investment in Class A Certificates should consider
whether such investment will give rise to prohibited transactions under ERISA or
the Code.
 
     The U.S. Department of Labor ("Labor") has issued regulations (29 C.F.R.
Section 2510.3-101) concerning the definition of what constitutes the assets of
a Plan (the "Plan Asset Regulations"), which provide that, as a general rule,
the underlying assets and properties of corporations, partnerships, trusts and
certain other entities in which a Plan makes an "equity" investment (as opposed
to a "debt" investment) will be deemed for purposes of ERISA to be assets of the
investing Plan unless, among other exceptions, the equity participation by Plan
investors in the equity investment is not "significant". Under the Plan Asset
Regulations, equity participation by benefit plan investors is "significant" on
any date if, immediately after the most recent acquisition of the equity
interest, 25% or more of the value of any class of equity interests in the
entity is held by retirement plans, including Plans and plans not subject to
ERISA (such as governmental and church plans). Under the Plan Asset Regulations,
an "equity" investment is an investment in an entity other than an investment
treated as indebtedness under applicable local law and which has no substantial
equity features. The beneficial interest in a trust, the undivided ownership
interest in property and the profit interest in a partnership are deemed to be
equity investments for this purpose.
 
     If an investing Plan's assets were deemed (under the Plan Asset Regulations
or other authority) to include an interest in the Mortgage Loans and any other
assets of the Trust, and not merely an interest in the Class A Certificates, the
assets of the Trust would become subject to the fiduciary standards of ERISA,
and necessary operational Trust transactions involving the Depositor, the Master
Servicer, the Sub-servicers, the Trustee, the Underwriter, the Certificate
Insurer, or any of their affiliates might constitute prohibited transactions,
unless an exemption applies. One such exemption which may be applicable to the
acquisition and holding of the Class A Certificates or to the servicing of the
Mortgage Loans is noted below. See also "ERISA Considerations" in the
Prospectus.
 
     Regardless of whether the Mortgage Loans and any other assets of the Trust
would be considered "plan assets" for purposes of ERISA, the acquisition or
holding of Class A Certificates on behalf of a Plan could still be considered to
give rise to a prohibited transaction if the Trust is or becomes a party in
interest or disqualified person with respect to such Plan, or if a subsequent
transfer of Class A Certificates is made between a Plan and such party in
interest or disqualified person, unless an exemption applies. One such exemption
which may be applicable to such transactions is noted below. See also "ERISA
Considerations" in the Prospectus.
 
     Labor has granted an individual administrative exemption to First Union
Corporation and its affiliates, Prohibited Transaction Exemption ("PTE") 96-22
("Underwriter Exemption"), from certain of the prohibited transaction rules of
ERISA and the Code with respect to the initial purchase, the holding and the
subsequent resale in the secondary market by Plans of pass-through certificates
representing beneficial undivided ownership interests in the assets of a trust
that consist of certain receivables, loans and other obligations that meet the
conditions and requirements of the Underwriter Exemption which may be applicable
to the Class A Certificates if First Union Corporation or any of its affiliates
is either the sole underwriter or the manager or co-manager of the underwriting
syndicate, or a selling or placement agent. On July 21, 1997, PTE 96-22 was
amended and consolidated with other similar exemptions in the form of PTE 97-34.
 
     The Underwriter Exemption provides relief from the restrictions of sections
406(a) and 407 of ERISA and the excise taxes imposed under section 4975(c)(1)(A)
through (D) of the Code, if the general conditions outlined below are satisfied,
in connection with (i) the direct or indirect sale, exchange or transfer of
Class A Certificates in the initial issuance of such certificates between the
Issuer or the Underwriter and a Plan, (ii) the direct or indirect acquisition or
disposition of Class A Certificates by a Plan in the secondary market, and (iii)
the continued holding of Class A Certificates so acquired. However, the
Underwriter Exemption does not provide an exemption from the restrictions of
sections 406(a)(1)(E), 406(a)(2) and 407 of ERISA for the acquisition or holding
of a Class A Certificate on behalf of an "Excluded Plan" by any person who has
discretionary authority or renders investment advice with respect to the assets
of that "Excluded Plan." For purposes of the Class A Certificates, an "Excluded
Plan" is a Plan sponsored by any the Depositor, the Master Servicer, any
Sub-servicer, the Trustee, the Underwriter, the Certificate Insurer, or any
 
                                      S-43
<PAGE>   106
 
other servicers or any obligor with respect to Mortgage Loans included in the
Trust constituting more than 5% of the aggregate unamortized principal balance
of the assets in the Trust or any affiliate of such parties (the "Restricted
Group").
 
     In addition, the Underwriter Exemption provides relief from the
self-dealing/conflict of interest restrictions of sections 406(b)(1) and (b)(2)
of ERISA and the excise taxes imposed under section 4975(c)(1)(E) of the Code in
connection with the direct or indirect sale, exchange or transfer of Class A
Certificates in the initial issuance of such certificates between the Issuer or
the Underwriter and a Plan, and the continued holding of Class A Certificates so
acquired, if (i) the person who has discretionary authority or renders
investment advice with respect to the investment of Plan assets in the Class A
Certificates (or its affiliate) is an obligor with respect to 5% or less of the
fair market value of the Mortgage Loans contained in the Trust, (ii) solely in
the case of an acquisition of Class A Certificates in connection with the
initial issuance of such certificates, at least 50% of each class of
certificates in which Plans have invested is acquired by persons independent of
the members of the Restricted Group and at least 50% of the aggregate interest
in the Trust is acquired by persons independent of the Restricted Group, (iii)
the Plan is not an Excluded Plan, (iv) the Plan's investment in each class of
certificates does not exceed 25% of the certificates of that class outstanding
at the time of the Plan's acquisition and after the Plan's acquisition of Class
A Certificates, no more than 25% of the assets over which the fiduciary has
investment authority are invested in securities of a trust containing assets
which are sold or serviced by the same entity, and (v) the general conditions
outlined below are met.
 
     The Underwriter Exemption also provides relief from the
self-dealing/conflict of interest restrictions of sections 406(b)(1) and (b)(2)
of ERISA and the excise taxes imposed under section 4975(c)(1)(E) of the Code in
connection with the direct or indirect acquisition or disposition of Class A
Certificates by a Plan in the secondary market, and the continued holding of
Class A Certificates so acquired, if the requirements specified in (i), (iii),
(iv) and (v) above are met.
 
     Finally, the Underwriter Exemption also provides an exemption from the
prohibited transaction restrictions for transactions in connection with the
servicing, management and operation of the Trust if such transactions are
carried out in accordance with the terms of a binding pooling and servicing
arrangement provided to, or described in all material respects in a prospectus
or private placement memorandum provided to, investing Plans and the general
conditions outlined below are satisfied. It is expected that this exemption will
be available, provided that the general conditions outlined below are satisfied.
 
     The general conditions which must be satisfied for the Underwriter
Exemption to apply are:
 
          (i) The acquisition of the Class A Certificates by a Plan is on terms
     (including the price for the Class A Certificates) that are at least as
     favorable to the Plan as they would be in an arm's length transaction with
     an unrelated party.
 
          (ii) The rights and interests evidenced by Class A Certificates
     acquired by the Plan are not subordinated to the rights and interests
     evidenced by any other Certificates of the Trust.
 
          (iii) The Class A Certificates acquired by the Plan have received a
     rating at the time of such acquisition that is in one of the three highest
     generic rating categories from any of Moody's Investor Service, Inc., Duff
     & Phelps Credit Rating Co., Standard & Poor's Structured Rating Group, or
     Fitch Investors Service, L.P. ("Authorized Rating Agencies").
 
          (iv) The investment pool consists only of assets of the type
     enumerated in the Underwriter Exemption, and which have been included in
     other investment pools; certificates evidencing interests in such other
     investment pools have been rated in one of the three highest generic rating
     categories by an Authorized Rating Agency for at least one year prior to a
     Plan's acquisition of certificates; and certificates evidencing interests
     in such other investment pools have been purchased by investors other than
     Plans for at least one year prior to a plan's acquisition of the Class A
     Certificates.
 
          (v) The sum of all payments made to and retained by the Underwriter in
     connection with the distribution or placement of the Class A Certificates
     represents not more than reasonable compensation
 
                                      S-44
<PAGE>   107
 
     for underwriting or placing the Class A Certificates. The sum of all
     payments made to and retained by the Depositor pursuant to the sale of the
     Mortgage Loans to the Trust represents not more than the fair market value
     of such Mortgage Loans. The sum of all payments made to and retained by the
     Master Servicer, the Sub-servicers or any other servicer represents not
     more than reasonable compensation for such services under the Agreement and
     reimbursement of the servicers' reasonable expenses in connection
     therewith.
 
          (vi) The Trustee is not an affiliate of any member of the Restricted
     Group.
 
          (vii) The Plan investing in the Class A Certificates is an "accredited
     investor" as defined in Rule 501(a)(1) of Regulation D under the Securities
     Act of 1933. Any Plan purchasing Class A Certificates will be deemed to
     have represented, by virtue of such purchase, that it is an accredited
     investor.
 
     Because the Class A Certificates are not subordinated to any other class of
Certificates, the second general condition set forth above is satisfied with
respect to the Class A Certificates. It is a condition of issuance of the Class
A Certificates that they be rated not lower than "AAA" and ["Aaa" by Standard &
Poor's Structured Rating Group and Moody's Investor Service, Inc.,
respectively]; thus, the third general condition set forth above is satisfied
with respect to the Class A Certificates as of the Closing Date. The Trustee
will not be an affiliate of any member of the Restricted Group on the Closing
Date; thus, the sixth general condition set forth above is satisfied with
respect to the Class A Certificates as of the Closing Date. A fiduciary of a
Plan contemplating the purchase of Class A Certificates in the secondary market
must make its own determination that, at the time of purchase, the Class A
Certificates continue to satisfy the third and sixth general conditions set
forth above. A fiduciary of a Plan contemplating the purchase of Class A
Certificates must make its own determination that the first, fifth and seventh
conditions set forth above will be satisfied with respect to the Class A
Certificates as of the date of such purchase.
 
     Because of the complexity of the prohibited transaction rules and the
relevant exemptions as well as the penalties imposed on prohibited transactions,
before purchasing a Class A Certificate in reliance on an exemption, including
the Underwriter Exemption, a fiduciary of a Plan should confirm that all
applicable requirements would be satisfied. Any Plan fiduciary considering the
purchase of a Class A Certificate should consult with its counsel with respect
to the potential applicability of ERISA and the Code to such investment.
Moreover, each Plan fiduciary should determine whether, under the general
fiduciary standards of investment prudence and diversification, an investment in
the Class A 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. See "ERISA Considerations" in the Prospectus.
 
     Any Plan purchasing Class A Certificates shall be deemed to have
represented, by virtue of such purchase, that such an investment is (i)
permitted under the governing benefit plan instruments, (ii) appropriate for the
benefit plan in view of its overall investment policy and the composition and
diversification of its portfolio, (iii) consistent with the requirements of
ERISA and the Code, and (iv) to the extent necessary, eligible for exemption
from the applicable prohibited transaction restrictions of ERISA and the Code.
 
                                USE OF PROCEEDS
 
     Substantially all of the net proceeds to be received from the sale of the
Offered Certificates will be applied by the Seller to the purchase price of the
Mortgage Loans and expenses connected with pooling the Mortgage Loans and
issuing the Certificates.
 
                        LEGAL INVESTMENT CONSIDERATIONS
 
     The Offered Certificates will not constitute "Mortgage Related Securities"
for purposes of the Secondary Mortgage Market Enhancement Act of 1984 ("SMMEA")
because, among other things, some of the mortgages securing the Mortgage Loans
are not first mortgages. Accordingly, many institutions with legal
 
                                      S-45
<PAGE>   108
 
authority to invest in comparably rated securities based on first mortgage loans
(i.e., "Mortgage Related Securities" under SMMEA) may not be legally authorized
to invest in the Offered Certificates. No representation is made as to whether
the Offered Certificates constitute legal investments for any entity under any
applicable statute, law, rule, regulation or order. Prospective purchasers are
urged to consult with their counsel concerning the status of the Offered
Certificates as legal investments for such purchasers prior to investing in the
Offered Certificates.
 
                                  UNDERWRITING
 
     First Union Capital Markets Corp., the [sole] underwriter (the
"Underwriter"), has agreed, on the terms and conditions of the Underwriting
Agreement and a Terms Agreement (together, the "Underwriting Agreement")
relating to the Offered Certificates, to purchase the entire principal amount of
the Offered Certificates offered hereby.
 
     In the Underwriting Agreement, the Underwriter has agreed, subject to the
terms and conditions set forth therein, to purchase all the Offered Certificates
offered hereby if any Offered Certificates are purchased.
 
     The distribution of the Offered Certificates by the Underwriter may be
effected from time to time in one or more negotiated transactions, or otherwise,
at varying prices to be determined, in each case, at the time of sale. This
Prospectus Supplement and the Prospectus may be used by First Union Capital
Markets Corp. or any of its affiliates in connection with offers and sales
related to market-making transactions in the Offered Certificates. The
Underwriter may act as principal or agent in such transactions.
 
     The Underwriter may effect such transactions by selling the Offered
Certificates to or through dealers, and such dealers may receive compensation in
the form of underwriting discounts, concessions or commissions from the
Underwriter. In connection with the sale of the Offered Certificates, the
Underwriter may be deemed to have received compensation from the Seller in the
form of underwriting compensation. The Underwriter and any dealers that
participate with the Underwriter in the distribution of the Offered Certificates
may be deemed to be underwriters and any commissions received by them and any
profit on the resale of the Offered Certificates positioned by them may be
deemed to be underwriting discounts and commissions under the Securities Act of
1933, as amended.
 
     The Seller and the Master Servicer have agreed to indemnify the Underwriter
against certain liabilities, including liabilities under the Securities Act of
1933, as amended.
 
     Upon receipt of a request by an investor who has received an electronic
Prospectus Supplement and Prospectus from the Underwriter or by such investor's
representative within the period during which there is an obligation to deliver
a Prospectus Supplement and Prospectus, the Underwriter will promptly deliver to
such investor a paper copy of the Prospectus Supplement and Prospectus.
 
     The Depositor, the Seller, the Master Servicer and the Document Custodian
are all affiliates of First Union Capital Markets Corp. The Underwriter or
agents and their associates may be customers of (including borrowers from),
engage in transactions with, and/or perform services for the Depositor, its
affiliates, and the [Trustee] in the ordinary course of business.

     Certain legal matters with respect to the Offered Certificates will be
passed upon for the Depositor by Moore & Van Allen, PLLC, Charlotte, North

& Van Allen, PLLC, Charlotte, North Carolina.
 
                               CERTIFICATE RATING
 
     It is a condition to the issuance of the Offered Certificates that they be
rated "AAA" by S&P, and "Aaa" by Moody's (together with S&P, the "Rating
Agencies"). A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning Rating Agency. The ratings assigned to the Offered Certificates
address the likelihood of the receipt of distributions due on the Offered
Certificates according to their terms. The ratings take into consideration,
among other things, the credit quality of the Mortgage Loans, the structural and
legal aspects associated with the Offered Certificates, and the claims-paying
ability of the Certificate Insurer. An adverse change in any of such factors or
in other factors may be a basis for the downward revision or withdrawal of the
rating of the Offered Certificates affected by such change. The ratings assigned
to the Offered Certificates do not represent any assessment of the likelihood
that principal prepayments might differ from those originally anticipated. The
rating does not address the possibility that the holders of the Offered
Certificates might suffer a lower than anticipated yield. There can be no
assurance as to whether any other rating agency will rate the Offered
Certificates, or if it does, what rating it will assign to the Offered
Certificates.

TITLE OF THE SECURITIES
 
Residential Mortgage Pass-Through Certificates (the "Certificates"), issuable in
a series (each, a "Series"). Each Series issued will be accompanied by a copy of
this Prospectus and a related Prospectus Supplement (the "related Prospectus
Supplement").
 
THE SERIES TRUST AND THE TRUSTEE
 
Each issuance of a Series will be made through a Trust (the "Trust") created
pursuant to a Pooling and Servicing Agreement (the "Agreement") among First
Union Residential Securitization Transactions, Inc. ("FURST") as the Depositor,
FUNB, as seller (the "Seller") and as master servicer (the "Master Servicer"),
and the trustee (the "Trustee"). A Trust Administrator may be specified in the
related Prospectus Supplement, which may be an affiliate of the Depositor.
 
DEPOSITOR
 
The Depositor will be First Union Residential Securitization Transactions, Inc.,
a North Carolina corporation. The Depositor is a wholly-owned, limited purpose
subsidiary of First Union National Bank ("FUNB"), a national banking association
(a wholly-owned subsidiary of First Union Corporation, a North Carolina
corporation). Neither First Union Corporation nor any of its affiliates,
including the Depositor, has guaranteed, or is or will be otherwise obligated
with respect to, the Certificates of any Series.
 
TRUST ASSETS
 
The Trust Fund for a Series of Certificates will include certain mortgage
related assets (the "Mortgage Assets") consisting of:
 
- - a pool (a "Mortgage Pool") of Mortgage Loans,
 
- - Agency Securities or
 
- - Private Mortgage-Backed Securities,
 
together with payments in respect of such Mortgage Assets and certain other
accounts, obligations or agreements, in each case as specified in the related
Prospectus Supplement. To the extent provided in the related Prospectus
Supplement, the Depositor will be obligated (subject only to the availability
thereof) to sell at a predetermined price, and the Trust Fund for a Series of
Certificates will be obligated to purchase (subject to the satisfaction of
certain conditions described in the applicable Agreement), additional Mortgage
Assets (the "Subsequent Mortgage Assets") from time to time (as frequently as
daily) within three months after the issuance of the Certificates having an
aggregate principal balance approximately equal to the amount on deposit in the
Pre-Funding Account (the "Pre-Funded Amount") on such closing date (the "Closing
Date").
 
SINGLE FAMILY LOANS
 
Unless otherwise specified in the related Prospectus Supplement, Mortgage Loans
will be secured by first, second or more junior liens on fee simple or leasehold
interests in one- to four-family properties.
 
If so specified, the Mortgage Loans may include cooperative apartment loans
("Cooperative Loans") secured by security interests in shares
 
                                        1
<PAGE>   120
 
issued by private, nonprofit, cooperative housing corporations ("Cooperatives")
and in the related proprietary leases or occupancy agreements granting exclusive
rights to occupy specific dwelling units in such Cooperatives' buildings.
 
If so specified in the related Prospectus Supplement, the Mortgage Assets of the
related Trust Fund may include mortgage participation certificates evidencing
interests in Mortgage Loans. Such Mortgage Loans may be conventional loans
(i.e., loans that are not insured or guaranteed by any governmental agency),
insured by the Federal Housing Authority ("FHA") or partially guaranteed by the
Veterans' Administration ("VA") as specified in the related Prospectus
Supplement. If specified in the related Prospectus Supplement, the Mortgage
Loans may be comprised of home equity loans ("Home Equity Loans"). Such Home
Equity Loans will be secured by first or second or more junior liens on fee
simple or leasehold interests in one- to four-family properties. See "Mortgage
Loan Program -- Underwriting Standards."
 
AGENCY SECURITIES
 
The agency securities (the "Agency Securities") evidenced by a Series of
Certificates will consist of:
 
- - mortgage participation certificates issued and guaranteed as to timely payment
  of interest and, unless otherwise specified in the related Prospectus
  Supplement, ultimate payment of principal by the Federal Home Loan Mortgage
  Corporation ("FHLMC Certificates"),
 
- - Guaranteed Mortgage Pass-Through Certificates issued and guaranteed as to
  timely payment of principal and interest by the Federal National Mortgage
  Association ("FNMA Certificates"),
 
- - fully modified pass-through mortgage-backed certificates guaranteed as to
  timely payment of principal and interest by the Government National Mortgage
  Association ("GNMA Certificates"),
 
- - 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 specified portion of the principal and interest
  distributions (but not all of such distributions) on certain FHLMC, FNMA or
  GNMA Certificates and, unless otherwise specified in the related Prospectus
  Supplement, guaranteed to the same extent as the underlying securities,
 
- - another type of pass-through certificate issued or guaranteed by GNMA, FNMA or
  FHLMC and described in the related Prospectus Supplement, or
 
- - a combination of such Agency Securities. All GNMA Certificates will be backed
  by the full faith and credit of the United States.
 
No FHLMC or FNMA Certificates will be backed, directly or indirectly, by the
full faith and credit of the United States. The Agency Securities may consist of
pass-through securities issued under FHLMC's Cash or Guarantor Program, the GNMA
I Program, the GNMA II Program or another program specified in the related
Prospectus Supplement. The payment characteristics of the Mortgage Loans
underlying the Agency Securities will be described in the related Prospectus
Supplement.
 
PRIVATE MORTGAGE-BACKED SECURITIES
 
Private Mortgage-Backed Securities (the "Private-Mortgage-Backed Securities")
may include:
 
- - mortgage pass-through certificates representing beneficial interests in a
  Mortgage Pool or
 
- - collateralized mortgage obligations secured by Mortgage Loans. Private
  Mortgage-Backed Securities 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 specified
  portion of the principal and interest distributions (but not all of such
  distributions) on certain Mortgage Loans.
 
Although individual Mortgage Loans underlying a Private Mortgage-Backed Security
may be insured or guaranteed by the United States or an agency or
instrumentality thereof, they need not be, and the Private Mortgage-Backed
Securities themselves will not be so insured or guaranteed. Private

DESCRIPTION OF THE CERTIFICATES
 
Each Certificate will represent the interest specified in the related Prospectus
Supplement in a Trust Fund created by the Depositor pursuant to an Agreement
among the Depositor, the Master Servicer and the Trustee for the related Series.
The Certificates of any Series may be issued in one or more classes as specified
in the related Prospectus Supplement. A Series of Certificates may include one
or more classes of senior Certificates (collectively, the "Senior Certificates")
and one or more classes of subordinate Certificates (collectively, the
"Subordinated Certificates").
 
Certain Series or classes of Certificates may be covered by insurance policies
or other forms of credit enhancement, in each case as described herein and in
the related Prospectus Supplement.
 
One or more classes of Certificates of each Series
 
- - may be entitled to receive distributions allocable only to principal, only to
  interest or to any combination thereof;
 
- - may be entitled to receive distributions only of prepayments of principal
  throughout the lives of the Certificates or during specified periods;
 
- - may be subordinated in the right to receive distributions of scheduled
  payments of principal, prepayments of principal, interest or any combination
  thereof to one or more other classes of Certificates of such Series throughout
  the lives of the Certificates or during specified periods;
 
- - may be entitled to receive such distributions only after the occurrence of
  events specified in the related Prospectus Supplement;
 
- - may be entitled to receive distributions in accordance with a schedule or
  formula or on the basis of collections from designated portions of the assets
  in the related Trust Fund;
 
- - as to Certificates entitled to distributions allocable to interest, may be
  entitled to receive interest at a fixed rate or a rate that is subject to
  change from time to time; and
 
- - as to Certificates entitled to distributions allocable to interest, may be
  entitled to distributions allocable to interest only after the occurrence of
  events specified in the related Prospectus Supplement and may accrue interest
  until such events occur, in each case as specified in the related Prospectus
  Supplement.
 
The timing, amounts, sequential order and priority of such distributions may
vary among classes, over time, or otherwise as specified in the related
Prospectus Supplement.
 
DISTRIBUTIONS ON THE CERTIFICATES
 
Distributions on the Certificates entitled thereto will be made monthly,
quarterly, semi-annually or at such other intervals and on the dates specified
in the related Prospectus Supplement (each, a "Distribution Date") out of the
payments received in respect of the assets of the related Trust Fund or other
assets pledged for the benefit of the Certificates as specified in the related
Prospectus Supplement. The amount allocable to payments of principal and
interest on any Distribution Date will be determined as specified in the related
Prospectus Supplement.
 
Unless otherwise specified in the related Prospectus Supplement, all
distributions will be made pro rata to Certificateholders of the class entitled
thereto. Unless otherwise specified in the related Prospectus Supplement, the
aggregate original Certificate Balance of the Certificates will equal the
aggregate distributions allocable to principal that such Certificates will be
entitled to receive.
 
If specified in the related Prospectus Supplement, the Certificates will have an
aggregate original Certificate Balance equal to the aggregate unpaid principal
balance of the Mortgage Assets as of the first day of the month of creation of
the Trust Fund and will bear interest in the aggregate at a rate equal to the
interest rate borne by the underlying Mortgage Loans (the "Mortgage Rate"),
Agency Securities or Private Mortgage-Backed Securities, net of the aggregate
servicing
 
                                        3

fees and any other amounts specified in the related Prospectus Supplement (the
"Pass-Through Rate").
 
The rate at which interest will be passed through to holders of each class of
Certificates entitled thereto may be a fixed rate or a rate that is subject to
change from time to time from the time and for the periods, in each case, as
specified in the related Prospectus Supplement. Any such rate may be calculated
on a loan-by-loan, weighted average or other basis, in each case as described in
the related Prospectus Supplement.
 
CREDIT ENHANCEMENT
 
The assets in a Trust Fund or the Certificates of one or more classes in the
related Series may have the benefit of one or more types of credit enhancement
described herein and in the related Prospectus Supplement. The protection
against losses afforded by any such credit support may be limited. The type,
characteristics and amount of credit enhancement will be determined based on the
characteristics of the Mortgage Loans underlying or comprising the Mortgage
Assets and other factors and will be established on the basis of requirements of
each Rating Agency rating the Certificates of such Series. One or more forms of
credit enhancement may be provided by an affiliate or affiliates of the
Depositor. See "Credit Enhancement" herein. Credit enhancement for a Series may
include one or more of the following types or such other credit enhancement
specified in the related Prospectus Supplement:
 
SUBORDINATION
 
A Series of Certificates may consist of one or more classes of Senior
Certificates and one or more classes of Subordinated Certificates. The rights of
the holders of the Subordinated Certificates of a Series to receive

subordinated to such rights of the holders of the Senior Certificates of the
same Series to the extent described in the related Prospectus Supplement.
 
RESERVE FUND
 
One or more reserve funds (each, a "Reserve Fund") may be established and
maintained for each Series. The related Prospectus Supplement will specify
whether or not any such Reserve Fund will be included in the corpus of the Trust
Fund for such Series and will also specify the manner of funding the related
Reserve Fund and the conditions under which the amounts in any such Reserve Fund
will be used to make distributions to holders of Certificates of a particular
class or released from the related Trust Fund.
 
MORTGAGE POOL INSURANCE POLICY
 
A mortgage pool insurance policy or policies ("Mortgage Pool Insurance Policy")
may be obtained and maintained for a Series, which shall be limited in scope,

specified percentage of the aggregate principal balance of all Mortgage Loans
included in the Mortgage Pool as of the first day of the month of issuance of
the related Series of Certificates or such other date as is specified in the
related Prospectus Supplement (the "Cut-off Date").
 
SPECIAL HAZARD INSURANCE POLICY
 
A special hazard insurance policy or policies ("Special Hazard Insurance
Policy") may be obtained and maintained for a Series, covering certain physical
risks that are not otherwise insured against by standard hazard insurance
policies. Each Special Hazard Insurance Policy will be limited in scope and will
cover losses pursuant to the provisions of each such Special Hazard Insurance
Policy as described in the related Prospectus Supplement.
 
BANKRUPTCY BOND
 
A bankruptcy bond or bonds ("Bankruptcy Bonds") may be obtained covering certain
losses resulting from action that may be taken by a bankruptcy court in
connection with a Mortgage Loan. The level of coverage and the limitations in
scope of each Bankruptcy Bond will be specified in the related Prospectus
Supplement.

CROSS SUPPORT
 
If specified in the related Prospectus Supplement, the beneficial ownership of
separate groups of assets included in a Trust Fund may be evidenced by separate
classes of the related Series of 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 beneficial ownership of one or more
asset groups prior to distributions to Subordinated Certificates evidencing a
beneficial ownership interest in other asset groups within the same Trust Fund.
 
LIMITED GUARANTEE
 
If specified in the related Prospectus Supplement, credit enhancement may be
provided in the form of a limited financial guarantee ("Limited Guarantee")
issued by a guarantor named therein.
 
LETTER OF CREDIT
 
Alternative credit support with respect to a Series of Certificates may be
provided by the issuance of a letter of credit ("Letter of Credit") by the bank
or financial institution specified in the related Prospectus Supplement. The
coverage, amount and frequency of any reduction in coverage provided by a Letter
of Credit issued with respect to a Series of Certificates will be set forth in
the related Prospectus Supplement.
 
SURETY BONDS
 
If specified in the related Prospectus Supplement, credit support with respect
to one or more classes of Certificates of a Series may be provided by the
issuance of a surety bond ("Surety Bond") issued by a financial guarantee
insurance company specified in the related Prospectus Supplement. The coverage,
amount and frequency of any reduction in coverage provided by a Surety Bond will
be set forth in the related Prospectus Supplement.
 
OVERCOLLATERALIZATION
 
If specified in the related Prospectus Supplement, credit support may consist of
overcollateralization whereby the aggregate principal amount of the Mortgage
Assets, including any Subsequent Mortgage Assets, exceeds the aggregate
Certificate Balance of the Certificates. Such overcollateralization may exist on
the Closing Date or develop thereafter as a result of the application of certain
interest collections, in excess of amounts necessary to pay the Pass-Through
Rate on the Certificates, received in connection with the Mortgage Assets,
including any Subsequent Mortgage Assets. The existence of any
overcollateralization and the manner, if any, by which it increases or
decreases, will be set forth in the related Prospectus Supplement.
 
ADVANCES
 
To the extent specified in the related Prospectus Supplement, the Master
Servicer and, if applicable, each mortgage servicing institution that services a
Mortgage Loan in a Mortgage Pool on behalf of the Master Servicer (a
"Sub-Servicer") will be obligated to advance amounts (each, an "Advance")
corresponding to delinquent principal and interest payments (or, in the case of
Home Equity Loans, interest payments only) on such Mortgage Loan (including, in
the case of Cooperative Loans, unpaid maintenance fees or other charges under
the related proprietary lease) until the first day of the month following the
date on which the related Mortgaged Property is sold at a foreclosure sale or
the related Mortgage Loan is otherwise liquidated, or until such other time as
specified in the related Prospectus Supplement. Any obligation to make Advances
may be subject to limitations as specified in the related Prospectus Supplement.
Advances will be reimbursable to the extent described herein and in the related
Prospectus Supplement.
 
OPTIONAL TERMINATION
 
The Servicer, the Depositor or, if specified in the related Prospectus
Supplement, the holder of the residual interest in a REMIC may have the option
to effect early retirement of a Series of Certificates through the purchase of
the Mortgage Assets and other assets in the related Trust Fund under the
circumstances and in the manner described in "The Pooling and Servicing
Agreement -- Termination; Optional Termination" herein and in the related
Prospectus Supplement.
 
In addition, if the related Prospectus Supplement provides that the property of
a Trust Fund will include a Pre-Funding Account (as such term is defined in the
related Prospectus Supplement, the "Pre-Funding Account"), a portion of a Series
of
 
                                        5
<PAGE>   124
 
Certificates will be subject to early retirement on or immediately following the
end of the Funding Period (as such term is defined in the related Prospectus
Supplement, the "Funding Period") in an amount and manner specified in the
related Prospectus Supplement.
 
LEGAL INVESTMENT CONSIDERATIONS
 
If any of the Series of Certificates will be "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984 ("SMMEA"), the
related Prospectus Supplement will specify which Classes of Certificates will
qualify.
 
If you are an institutional investor who can only make legal investments in
SMMEA eligible securities, you should consult your legal counsel to determine if
a Series of Certificates are "mortgage related securities" under SMMEA.
 
TAX STATUS
 
The related Prospectus Supplement for each Series of Certificates will specify
if the Trust will make election to be treated as a "real estate mortgage
investment conduit" ("REMIC") under the provisions of the Internal Revenue Code
of 1986, as amended (the "Code"). The election to be treated as a REMIC will
have federal income tax consequences for the Certificateholders.
 
ERISA CONSIDERATIONS
 
If you are a fiduciary of an employee benefit plan or other retirement plan or
arrangement that is subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), you must consult with legal advisors to determine if
purchasing or holding of Certificates is a prohibited transaction or otherwise
prohibited under ERISA.
 
Certain classes of Certificates may only be transferred if the Trustee and the
Depositor receive a letter of representations or an opinion of counsel that such
transfer will not violate ERISA or the Code. In addition, the letter of
representation or opinion of counsel must also state that the Trustee, Depositor
or the Master Servicer will not be subject to additional obligations.
 
CERTIFICATE RATING
 
Any certificate offered by this Prospectus and the accompanying Prospectus
Supplement will be rated in one of the four highest rating categories by at
least one nationally recognized rating organization. Any nationally recognized
rating organization selected by the Seller to rate any Series is a "Rating
Agency."
 
A rating is not a recommendation to buy, sell or hold securities and may be
revised or withdrawn at any time by the assigning Rating Agency. Each rating
should be evaluated independently of any other rating.

                                  RISK FACTORS
 
     You should consider the following risk factors in deciding whether to
purchase the Certificates.
 
Limited Liquidity..........  Although the Prospectus Supplement for a Series of
                             Certificates may indicate that the underwriter
                             intends to make a market in such Certificates, it
                             is under no obligation to do so. There can be no
                             assurance that a secondary market will develop or,
                             if a secondary market does develop, that it will
                             provide holders of such Certificates with liquidity
                             of investment or that it will continue for the
                             lives of such Certificates. The Certificates will
                             not be listed on any securities exchange.
 
General Economic
Conditions.................  General economic conditions have an impact on the
                             ability of borrowers to repay mortgage loans. Loss
                             of earnings, illness and other similar factors may
                             lead to an increase in delinquencies and bankruptcy
                             filings by borrowers. In the event of personal
                             bankruptcy of a borrower under a Mortgage Loan (a
                             "Mortgagor"), it is possible that the holders of
                             the related Certificates could experience a loss
                             with respect to such Mortgagor's Mortgage Loan. In
                             conjunction with a Mortgagor's bankruptcy, a
                             bankruptcy court may suspend or reduce the payments
                             of principal and interest to be paid with respect
                             to such Mortgage Loan, thus delaying or reducing
                             the amount received by the holders of the related
                             Certificates with respect to such Mortgage Loan.
                             Moreover, if a bankruptcy court prevents the
                             transfer of the related Mortgaged Property to the
                             related Trust Fund, any remaining balance on such
                             Mortgage Loan may not be recoverable. See "Mortgage
                             Loan Program" herein and "The Seller and the
                             Servicer -- Delinquency, Loan Loss and Foreclosure
                             Information" in the related Prospectus Supplement
                             for further information regarding the rates of
                             delinquency and net losses experienced on the
                             mortgage loans included in FUNB's servicing
                             portfolio.
 
Local Real Estate
Markets....................  An overall decline in the residential real estate
                             markets in the states in which the Mortgaged
                             Properties are located could adversely affect the
                             values of the Mortgaged Properties such that the
                             aggregate outstanding balance of the Mortgage Loans
                             equals or exceeds the value of the Mortgaged
                             Properties. The Depositor can neither predict such
                             declines nor quantify the impact of such declines
                             in property values nor predict how long and in
                             which states such declines may occur. During a
                             period of such declines, the rates of
                             delinquencies, foreclosures and losses on the
                             Mortgage Loans would be expected to be higher than
                             those experienced in the mortgage lending industry
                             in general.
 
Yield And Prepayment
  Considerations...........  The yield on the Certificates of each Series will
                             depend on the rate of principal payment (including
                             prepayments, liquidations due to defaults and
                             repurchases) on the Mortgage Loans and the price
                             paid by Certificateholders. Such yield may be
                             adversely affected by a higher or lower than
                             anticipated rate of prepayments on the related
                             Mortgage Loans. In addition, unless otherwise
                             specified in the related Prospectus Supplement, the
                             yield to investors may be adversely affected by
                             shortfalls which may result from the timing of the
                             receipt of partial prepayments or liquidations as
                             well as shortfalls not covered by the Master
                             Servicing Fee related to a particular Distribution
                             Date and which shortfalls result from the timing of
                             the receipt of full prepayments. The yield on
                             Certificates
 
                                        7
<PAGE>   126
 
                             entitling the holders thereof primarily or
                             exclusively to payments of interest on the Mortgage
                             Loans will be extremely sensitive to the rate of
                             prepayments on the related Mortgage Loans. In
                             addition, the yield on certain other types of
                             classes of Certificates may be relatively more
                             sensitive to the rate of prepayment of the related
                             Mortgage Loans than other classes of Certificates.
                             Prepayments are influenced by a number of factors,
                             including prevailing mortgage market interest
                             rates, local and national economic conditions and
                             homeowner mobility. See "Yield and Prepayment
                             Considerations."
 
Limited Obligations........  Except for any related insurance policies and any
                             reserve fund or credit enhancement described in the
                             applicable Prospectus Supplement, the Mortgage
                             Assets included in the related Trust Fund will be
                             the sole source of payments on the Certificates of
                             a Series. The Certificates of any Series will not
                             represent an interest in or obligation of the
                             Depositor, the Seller, the Master Servicer, the
                             Trustee or any of their affiliates, except for the
                             Depositor's and the Seller's limited obligations
                             with respect to certain breaches of their
                             respective representations and warranties. The
                             Certificates of any Series will not be guaranteed
                             or insured by any governmental agency or
                             instrumentality, the Depositor, the Master
                             Servicer, the Trustee, any of their affiliates or
                             any other person. Consequently, in the event that
                             payments on the Mortgage Assets are insufficient or
                             otherwise unavailable to make all payments required
                             on the Certificates, there will be no recourse to
                             the Depositor, the Master Servicer, the Trustee or,
                             except as specified in the applicable Prospectus
                             Supplement, any other entity.
 
Limitations, Reduction And
  Substitution Of Credit
  Enhancement..............  With respect to each Series of Certificates, credit
                             enhancement may be provided in limited amounts to
                             cover certain types of losses on the underlying
                             Mortgage Loans. Credit enhancement will be provided
                             in one or more of the forms referred to herein,
                             including, but not limited to: subordination of
                             other classes of Certificates of the same Series; a
                             limited guarantee; a letter of credit; a pool
                             insurance policy; a special hazard insurance
                             policy; a mortgagor bankruptcy bond; a reserve
                             fund; cross support; FHA Insurance and VA
                             Guarantee; a surety bond; and any combination
                             thereof. See "Credit Enhancement" herein.
                             Regardless of the form of credit enhancement
                             provided, the amount of coverage will be limited in
                             amount and in most cases will be subject to
                             periodic reduction in accordance with a schedule or
                             formula. Furthermore, such credit enhancements may
                             provide only very limited coverage as to certain
                             types of losses, and may provide no coverage as to
                             certain other types of losses. All or a portion of
                             the credit enhancement for any Series of
                             Certificates will generally be permitted to be
                             reduced, terminated or substituted for, if each
                             applicable rating agency confirms that the then
                             current rating thereof will not be adversely
                             affected. See "Credit Enhancement."
 
Realization Upon
Nonperforming Loans; Delays
  and Expenses Associated
  with Legal Actions.......  An action to foreclose a Mortgage Loan is regulated
                             by statutes and rules and is subject to a court's
                             equitable powers. A foreclosure action is subject
                             to many of the delays and expenses of other
                             lawsuits if defenses
 
                                        8
<PAGE>   127
 
                             or counterclaims are interposed, sometimes
                             requiring several years to complete. Furthermore,
                             an action to obtain a deficiency judgment also is
                             regulated by statutes and rules, and the amount of
                             a deficiency judgment may be limited by law. In the
                             event of a default by a borrower, these
                             restrictions, among others, may impede the ability
                             of the Master Servicer to foreclose on or to sell
                             the Mortgaged Property or to obtain a deficiency
                             judgment in connection therewith. If the protection
                             afforded the Certificateholders of a Series by the
                             credit enhancement, if any, for such Series is
                             exhausted, such restrictions may delay
                             distributions to such Certificateholders and may
                             ultimately limit the amounts distributed with
                             respect to such defaulted Mortgage Loans and result
                             in a loss to such Certificateholders on their
                             investments. See "Certain Legal Aspects of the
                             Mortgage Loans."
 
Junior Liens...............  Mortgages securing Home Equity Loans are often
                             junior liens subordinate to the rights of the
                             mortgagee under the related senior mortgage or
                             mortgages. The proceeds from any liquidation,
                             insurance or condemnation proceedings will be
                             available to satisfy the outstanding balance of
                             such junior mortgage only to the extent that the
                             claims of such senior mortgagees have been
                             satisfied in full, including any related
                             foreclosure costs. In addition, a junior mortgagee
                             may not foreclose on the property securing a junior
                             mortgage unless it forecloses subject to the senior
                             mortgages, in which case it must either pay the
                             entire amount due on the senior mortgages to the
                             senior mortgagees at or prior to the foreclosure
                             sale or undertake the obligation to make payments
                             on the senior mortgages in the event the mortgagor
                             is in default thereunder. The Trust Fund will not
                             have any source of funds to satisfy the senior
                             mortgages to make payments due to the senior
                             mortgagees.
 
Subordinated
Certificates...............  A Series of Certificates may consist of one or more
                             classes of Senior Certificates and one or more
                             classes of Subordinated Certificates. The rights of
                             the holders of Subordinated Certificates to receive
                             distributions from the related Trust Fund will be
                             subordinated to the rights of the holders of Senior
                             Certificates of the same Series to receive such
                             distributions. The effect of such subordination
                             generally is that holders of Subordinated
                             Certificates may experience losses on the
                             underlying Mortgage Assets before or to a greater
                             extent than holders of Senior Certificates. The
                             Prospectus Supplement for each Series will specify
                             the rights of holders of Subordinated Certificates
                             in relation to the holders of Senior Certificates
                             as well as the extent and circumstances of any such
                             subordination. See "Credit
                             Enhancement -- Subordination."
 
Other Legal
Considerations.............  Applicable state laws generally regulate interest
                             rates and other charges, and require certain
                             disclosures to borrowers. In addition, many states
                             have other laws, such as consumer protection laws,
                             unfair and deceptive practices acts and debt
                             collection practices acts which may apply to the
                             origination or collection of the Mortgage Loans.
                             Depending on the provisions of the applicable law,
                             violations of these laws may limit the ability of
                             the Master Servicer to collect all or part of the
                             principal of, or interest on, the Mortgage Loans,
                             may entitle the borrower to a refund of amounts
                             previously paid and, in addition, could subject the
                             related Trust Fund to damages and administrative
                             enforcement. See "Certain Legal Aspects of the
                             Mortgage Loans."

<PAGE>   128
 
                                THE TRUST FUND*
 
     The Trust Fund for each Series will be held by the Trustee for the benefit
of the related Certificateholders. Each Trust Fund will consist of certain
mortgage-related assets (the "Mortgage Assets") consisting of (A) a mortgage
pool (a "Mortgage Pool") comprised of Mortgage Loans, (B) Agency Securities or
(C) Private Mortgage-Backed Securities, in each case as specified in the related
Prospectus Supplement, together with payments in respect of such Mortgage Assets
and certain other accounts, obligations or agreements, in each case as specified
in the related Prospectus Supplement.
 
     The Certificates will be entitled to payment from the assets of the related
Trust Fund or Funds or other assets pledged for the benefit of the
Certificateholders as specified in the related Prospectus Supplement and will
not be entitled to payments in respect of the assets of any other trust fund
established by the Depositor. Unless otherwise specified in the related
Prospectus Supplement, the Mortgage Assets of any Trust Fund will consist of
Mortgage Loans, Agency Securities or Private Mortgage-Backed Securities but not
a combination thereof.
 
     The Mortgage Assets may be acquired by the Depositor, either directly or
through affiliates, in the open market or in privately negotiated transactions,
from originators or sellers that may be affiliates of the Depositor (the
"Sellers") and conveyed by the Depositor to the related Trust Fund. The Sellers
may have originated the Mortgage Assets or acquired the Mortgage Assets from the
originators or other entities. See "Mortgage Loan Program -- Underwriting
Standards."
 
     The following is a brief description of the Mortgage Assets expected to be
included in the Trust Funds. If specific information respecting the Mortgage
Assets is not known at the time the related Series of Certificates initially is
offered, more general information of the nature described below will be provided
in the related Prospectus Supplement, and final specific information will be set
forth in a Current Report on Form 8-K to be available to investors on the date
of issuance thereof and to be filed with the Securities and Exchange Commission
within fifteen days after the initial issuance of such Certificates (the
"Detailed Description"). A schedule of the Mortgage Assets relating to such
Series will be attached to the Agreement delivered to the Trustee upon delivery
of the Certificates.
 
GENERAL -- THE MORTGAGE LOANS
 
     For purposes hereof, the real property that secures repayment of the
Mortgage Loans are collectively referred to as "Mortgaged Properties." The
Mortgaged Properties may be located in any one of the fifty states, the District
of Columbia, Guam, Puerto Rico or any other territory of the United States.
Mortgage Loans with certain Loan-to-Value Ratios and/or certain principal
balances may be covered wholly or partially by primary mortgage guaranty
insurance policies (each, a "Primary Mortgage Insurance Policy"). The existence,
extent and duration of any such coverage will be described in the applicable
Prospectus Supplement. No Primary Mortgage Insurance Policy will be required for
any home equity loan.
 
     The Mortgage Loans in a Mortgage Pool will have monthly payment dates as
set forth in the related Prospectus Supplement. The payment terms of the
Mortgage Loans to be included in a Trust Fund will be described in the related
Prospectus Supplement and may include any of the following features or
combination thereof or other features described in the related Prospectus
Supplement:
 
          (a) Interest may be payable at a fixed rate, a rate adjustable from
     time to time in relation to an index (which will be specified in the
     related Prospectus Supplement), a rate that is fixed for a period of time
     or under certain circumstances and is followed by an adjustable rate, a
     rate that otherwise varies from time to time, or a rate that is convertible
     from an adjustable rate to a fixed rate. Changes to an adjustable rate may
     be subject to periodic limitations, maximum rates, minimum rates or a
     combination
 
- ---------------
 
* Whenever the terms "Mortgage Pool" and "Certificates" are used in this
  Prospectus, such terms will be deemed to apply, unless the context indicates
  otherwise, to one specific Mortgage Pool and the Certificates relating to a
  single trust fund (the "Trust Fund") consisting primarily of the Mortgage
  Loans in such Mortgage Pool. Similarly, the term "Pass-Through Rate" will
  refer to the Pass- Through Rate borne by the Certificates of one specific
  Series and the term "Trust Fund" will refer to one specific Trust Fund.
                                       10
<PAGE>   129
 
     of such limitations. Accrued interest may be deferred and added to the
     principal of a loan for such periods.
 
          (b) Principal may be payable on a level debt service basis to fully
     amortize the loan over its term, may be calculated on the basis of an
     assumed amortization schedule that is significantly longer than the
     original term to maturity or on an interest rate that is different from the
     interest rate on the Mortgage Loan or may not be amortized during all or a
     portion of the original term. Payment of all or a substantial portion of
     the principal may be due on maturity ("balloon payments"). Principal may
     include interest that has been deferred and added to the principal balance
     of the Mortgage Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the loan, may increase over a specified period of time or may
     change from period to period. Loans may include limits on periodic
     increases or decreases in the amount of monthly payments and may include
     maximum or minimum amounts of monthly payments.
 
          (d) The Mortgage Loans generally may be prepaid at any time without
     the payment of any prepayment fee. If so specified in the related
     Prospectus Supplement, some prepayments of principal may be subject to a
     prepayment fee, which may be fixed for the life of any such Mortgage Loan
     or may decline over time, and may be prohibited for the life of any such
     Mortgage Loan or for certain periods ("lockout periods"). Certain Mortgage
     Loans may permit prepayments after expiration of the applicable lockout
     period and may require the payment of a prepayment fee in connection with
     any such subsequent prepayment. Other Mortgage Loans may permit prepayments
     without payment of a fee unless the prepayment occurs during specified time
     periods.
 
          (e) The loans may include "due-on-sale" clauses which permit the
     mortgagee to demand payment of the entire mortgage loan in connection with
     the sale or certain transfers of the related Mortgaged Property. Other
     Mortgage Loans may be assumable by persons meeting the then applicable
     underwriting standards of the Seller.
 
     Certain Mortgage Loans may be originated or acquired in connection with
employee relocation programs. The real property constituting security for
repayment of a Mortgage Loan may be located in any one of the fifty states, the
District of Columbia, Guam, Puerto Rico or any other territory of the United
States.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Mortgage Loans will be covered by standard hazard insurance policies insuring
against losses due to fire and various other causes.
 
     The Mortgage Loans will be covered by primary mortgage insurance policies
to the extent provided in the related Prospectus Supplement. All Mortgage Loans
will have been purchased by the Depositor, either directly or through an
affiliate, from one or more Sellers.
 
     A Trust Fund may contain certain Mortgage Loans, which include provisions
whereby a third party partially subsidizes the borrower's monthly payments
during the early years of the Mortgage Loan ("Buydown Loans"), the difference to
be made up from a fund (a "Buydown Fund") contributed by such third party at the
time of origination of the 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
borrower will increase during the buydown period as a result of normal increases
in compensation and of inflation, so that the borrower 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 Prospectus Supplement will contain
information with respect to any Buydown Loan concerning limitations on the
interest rate paid by the borrower initially, on annual increases in the
interest rate and on the length of the buydown period.
 
     Each Prospectus Supplement will contain information, as of the date of such
Prospectus Supplement and to the extent then specifically known to the
Depositor, with respect to the Mortgage Loans contained in the related Mortgage
Pool, including (i) the aggregate outstanding principal balance and the average
outstanding principal balance of the Mortgage Loans as of the applicable Cut-off
Date, (ii) the type of property securing the Mortgage Loans (e.g., separate
residential properties, individual units in condominiums in buildings
 
                                       11
<PAGE>   130
 
owned by cooperative housing corporations, vacation and second homes, or other
similar real property), (iii) the original terms to maturity of the Mortgage
Loans, (iv) the largest principal balance and the smallest principal balance of
any of the Mortgage Loans, (v) the earliest origination date and latest maturity
date of any of the Mortgage Loans, (vi) the aggregate principal balance of
Mortgage Loans having Loan-to-Value Ratios or Combined Loan-to-Value Ratios at
origination exceeding 80%, (vii) the maximum and minimum per annum rates at
which the related Mortgage Notes accrue interest (the "Mortgage Rate"), and
(viii) the geographical distribution of the Mortgage Loans.
 
     The "Loan-to-Value Ratio" of a Mortgage Loan at any given time is the
fraction, expressed as a percentage, the numerator of which is the original
principal balance of the related Mortgage Loan and the denominator of which is
the Collateral Value of the related Mortgaged Property. Unless otherwise
specified in the related Prospectus Supplement, the "Collateral Value" of a
Mortgaged Property is the lesser of (a) the appraised value determined in an
appraisal obtained by the originator at origination of such Mortgage Loan and
(b) the sales price for such property.
 
     The "Combined Loan-to-Value Ratio" of any Home Equity Loan is the ratio
(expressed as a percentage) of (i) the sum of (a) the original principal balance
of such Mortgage Loan at the date of origination (which for purposes of the
related Prospectus Supplement includes certain financed fees and insurance
premiums) plus (b) the outstanding balance of the senior liens, if any, divided
by (ii) the lesser of (a) the value of the related Mortgaged Property, based
upon the appraisal, if any, or drive-by evaluation made at the time of
origination of the Mortgage Loan and (b) the purchase price of the Mortgaged
Property if the Mortgage Loan proceeds were used to purchase the Mortgaged
Property. For Mortgage Loans having low original principal balances, the
Combined Loan-to-Value Ratios of the Mortgage Loans will reflect certain
judgments of the Seller's underwriters with respect to the value of the
Mortgaged Property made at the time the Mortgage Loans were originated or
acquired. See "Mortgage Loan Program -- Underwriting Standards."
 
     The Depositor will cause the Mortgage Loans comprising each Mortgage Pool
to be assigned to the Trustee named in the related Prospectus Supplement for the
benefit of the holders of the Certificates of the related Series. Unless
otherwise specified in the related Prospectus Supplement, the only obligations
of the Depositor with respect to a Series of Certificates will be to obtain
certain representations and warranties from the Sellers and to assign to the
Trustee for such Series of Certificates the Depositor's rights with respect to
such representations and warranties. See "The Pooling and Servicing
Agreement -- Assignment of Mortgage Assets."
 
     The Master Servicer named in the related Prospectus Supplement will service
the Mortgage Loans, either directly or through other mortgage servicing
institutions (each, a "Sub-Servicer"), pursuant to a Pooling and Servicing
Agreement (each, an "Agreement"). The Master Servicer and any Sub-Servicers will
each receive a fee for such services. See "Mortgage Loan Program" and "The
Pooling and Servicing Agreement." With respect to Mortgage Loans serviced by the
Master Servicer through a Sub-Servicer, the Master Servicer will remain liable
for its servicing obligations under the related Agreement as if the Master
Servicer alone were servicing such Mortgage Loans. The obligations of the Master
Servicer with respect to the Mortgage Loans will consist principally of its
contractual servicing obligations under the related Agreement (including its
obligation to enforce the obligations of the Sub-Servicers or Sellers, or both,
as more fully described herein under "Mortgage Loan Program -- Representations
by Sellers; Repurchases" and "The Pooling and Servicing Agreement -- Assignment
of Mortgage Assets") and its obligation to make certain cash advances in the
event of delinquencies in payments on or with respect to the Mortgage Loans in
the amounts described herein under "Description of the
Certificates -- Advances." The obligations of the Master Servicer to make
advances may be subject to limitations, to the extent provided herein and in the
related Prospectus Supplement.
 
     Single Family and Cooperative Loans.  Unless otherwise specified in the
related Prospectus Supplement, Mortgage Loans will consist of mortgage loans,
deeds of trust or participations or other beneficial interests therein, secured
by first, second or more junior liens on single family (i.e., one- to
four-family) residential properties. If so specified, the Mortgage Loans may
include cooperative apartment loans ("Cooperative Loans") secured by security
interests in shares issued by private, non-profit, cooperative
 
                                       12
<PAGE>   131
 
housing corporations ("Cooperatives") and in the related proprietary leases or
occupancy agreements granting exclusive rights to occupy specific dwelling units
in such Cooperatives' buildings. If so specified in the related Prospectus
Supplement, the Mortgage Assets of the related Trust Fund may include mortgage
participation certificates evidencing interests in Mortgage Loans. Such loans
may be conventional loans (i.e., loans that are not insured or guaranteed by any
governmental agency) or loans insured by the FHA or partially guaranteed by the
VA, as specified in the related Prospectus Supplement.
 
     The Mortgaged Properties relating to single family Mortgage Loans will
consist of detached or semi-detached one-family dwelling units, two- to
four-family dwelling units, townhouses, rowhouses, individual condominium units,
individual units in planned unit developments, and certain other dwelling units.
Such Mortgaged Properties may include vacation and second homes, investment
properties and leasehold interests. In the case of leasehold interests, the term
of the leasehold will exceed the scheduled maturity of the Mortgage Loan by at
least five years, unless otherwise specified in the related Prospectus
Supplement. Certain Mortgage Loans may be originated or acquired in connection
with corporate programs, including employee relocation programs. In limited
instances, a borrower who uses the dwelling unit as a primary residence may also
make some business use of the property.
 
     Home Equity Loans.  As described more fully in the related Prospectus
Supplement, the Mortgage Loans constituting a Trust Fund may comprise a pool of
home equity loans ("Home Equity Loans"). Home Equity Loans are mortgage loans
made for purposes that include: purchase money transactions, refinancings (both
cash-out and no-cash-out), home improvements and construction-to-permanent
financing. Unless otherwise specified in the related Prospectus Supplement, Home
Equity Loans will generally be secured by a lien on the related Mortgaged
Property of a first or second priority. Unless otherwise specified in the
related Prospectus Supplement, Home Equity Loans are generally made to
Mortgagors with credit grades (as determined by the Seller from time to time) A2
and below. The Mortgaged Properties securing the Home Equity Loans may
constitute single-family dwellings, mobile and manufactured housing and, in
limited cases, other types of residential property as described in the related
Prospectus Supplement.
 
AGENCY SECURITIES
 
     Government National Mortgage Association.  GNMA is a wholly-owned corporate
instrumentality of the United States with the United States Department of
Housing and Urban Development. Section 306(g) of Title II 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
which represent an interest in a pool of mortgage loans insured by the Federal
Housing Authority ("FHA") under the Housing Act, or Title V of the Housing Act
of 1949 ("FHA Loans"), or partially guaranteed by the VA under the Servicemen's
Readjustment Act of 1944, as amended, or Chapter 37 of Title 38, United States
Code ("VA Loans").
 
     Section 306(g) of the Housing Act provides that "the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guaranty under this subsection." In order to meet
its obligations under any such guarantee, GNMA may, under Section 306(d) of the
Housing Act, borrow from the United States Treasury in an unlimited amount which
is at any time sufficient to enable GNMA to perform its obligations under its
guarantee.
 
     GNMA Certificates.  Each GNMA Certificate held in a Trust Fund (which may
be issued under either the GNMA I program or the GNMA II program) will be a
"fully modified pass-through" mortgage-backed certificate issued and serviced by
a mortgage banking company or other financial concern ("GNMA Issuer") approved
by GNMA or approved by FNMA as a seller-servicer of FHA Loans and/or VA Loans.
The mortgage loans underlying the GNMA Certificates will consist of FHA Loans
and/or VA Loans. Each such mortgage loan is secured by a one- to four-family
residential property. GNMA will approve the issuance of each such GNMA
Certificate in accordance with a guaranty agreement (a "Guaranty Agreement")
between GNMA and the GNMA Issuer. Pursuant to its Guaranty Agreement, a GNMA
Issuer will be required to advance its own funds in order to make timely
payments of all amounts due on each such GNMA Certificate, even if the payments
received by the GNMA Issuer on the FHA Loans or VA Loans underlying each such
GNMA Certificate are less than the amounts due on each such GNMA Certificate.

     The full and timely payment of principal of and interest on each GNMA
Certificate will be guaranteed by GNMA, which obligation is backed by the full
faith and credit of the United States. Each such GNMA Certificate will have an
original maturity of not more than 40 years (but may have original maturities of
substantially less than 40 years). Each such GNMA Certificate will be based on
and backed by a pool of FHA Loans or VA Loans secured by one- to four-family
residential properties and will provide for the payment by or on behalf of the
GNMA Issuer to the registered holder of such GNMA Certificate of scheduled
monthly payments of principal and interest equal to the registered holder's
proportionate interest in the aggregate amount of the monthly principal and
interest payment on each FHA Loan or VA Loan underlying such GNMA Certificate,
less the applicable servicing and guarantee fee which together equal the
difference between the interest on the FHA Loan or VA Loan and the pass-through
rate on the GNMA Certificate. In addition, each payment will include
proportionate pass-through payments of any prepayments of principal on the FHA
Loans or VA Loans underlying such GNMA Certificate and liquidation proceeds in
the event of a foreclosure or other disposition of any such FHA Loans or VA
Loans.
 
     If a GNMA Issuer is unable to make the payments on a GNMA Certificate as it
becomes due, it must promptly notify GNMA and request GNMA to make such payment.
Upon notification and request, GNMA will make such payments directly to the
registered holder of such GNMA Certificate. In the event no payment is made by a
GNMA Issuer and the GNMA Issuer fails to notify and request GNMA to make such
payment, the holder of such GNMA Certificate will have recourse only against
GNMA to obtain such payment. The Trustee or its nominee, as registered holder of
the GNMA Certificates held in a Trust Fund, will have the right to proceed
directly against GNMA under the terms of the Guaranty Agreements relating to
such GNMA Certificates for any amounts that are not paid when due.
 
     All mortgage loans underlying a particular GNMA I Certificate must have the
same interest rate (except for pools of mortgage loans secured by manufactured
homes) over the term of the loan. The interest rate on such GNMA I Certificate
will equal the interest rate on the mortgage loans included in the pool of
mortgage loans underlying such GNMA I Certificate, less one-half percentage
point per annum of the unpaid principal balance of the mortgage loans.
 
     Mortgage loans underlying a particular GNMA II Certificate may have per
annum interest rates that vary from each other by up to one percentage point.
The interest rate on each GNMA II Certificate will be between one-half
percentage point and one and one-half percentage points lower than the highest
interest rate on the mortgage loans included in the pool of mortgage loans
underlying such GNMA II Certificate (except for pools of mortgage loans secured
by manufactured homes).
 
     Regular monthly installment payments on each GNMA Certificate held in a
Trust Fund will be comprised of interest due as specified on such GNMA
Certificate plus the scheduled principal payments on the FHA Loans or VA Loans
underlying such GNMA Certificate due on the first day of the month in which the
scheduled monthly installments on such GNMA Certificate are due. Such regular
monthly installments on each such GNMA Certificate are required to be paid to
the Trustee as registered holder by the 15th day of each month in the case of a
GNMA I Certificate and are required to be mailed to the Trustee by the 20th day
of each month in the case of a GNMA II Certificate. Any principal prepayments on
any FHA Loans or VA Loans underlying a GNMA Certificate held in a Trust Fund or
any other early recovery of principal on such loan will be passed through to the
Trustee as the registered holder of such GNMA Certificate.
 
     GNMA Certificates may be backed by graduated payment mortgage loans or by
"buydown" mortgage loans for which funds will have been provided (and deposited
into escrow accounts) for application to the payment of a portion of the
borrowers' monthly payments during the early years of such mortgage loan.
Payments due the registered holders of GNMA Certificates backed by pools
containing "buydown" mortgage loans will be computed in the same manner as
payments derived from other GNMA Certificates and will include amounts to be
collected from both the borrower and the related escrow account. The graduated
payment mortgage loans will provide for graduated interest payments that, during
the early years of such mortgage loans, will be less than the amount of stated
interest on such mortgage loans. The interest not so paid will be added to the
principal of such graduated payment mortgage loans and, together with interest
thereon, will be paid in subsequent years. The obligations of GNMA and of a GNMA
Issuer will be the same
 
                                       14
<PAGE>   133
 
irrespective of whether the GNMA Certificates are backed by graduated payment
mortgage loans or "buydown" mortgage loans. No statistics comparable to the
FHA's prepayment experience on level payment, non-"buydown" mortgage loans are
available in respect of graduated payment or "buydown" mortgages. GNMA
Certificates related to a Series of Certificates may be held in book-entry form.
 
     As described above, the GNMA Certificates included in a Trust Fund, 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 Prospectus Supplement.
 
     Federal Home Loan Mortgage Corporation.  FHLMC is a shareholder-owned
corporation that was created pursuant to Title III of the Emergency Home Finance
Act of 1970, as amended (the "FHLMC Act"). FHLMC was established primarily for
the purpose of increasing the availability of mortgage credit for the financing
of 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 mortgage loans or
participation interests in such mortgage loans and the sale of the mortgage
loans or participations so purchased in the form of mortgage securities,
primarily FHLMC Certificates. FHLMC is confined to purchasing, so far as
practicable, mortgage loans that it deems to be of such quality, type and class
as to meet generally the purchase standards imposed by private institutional
mortgage investors.
 
     FHLMC Certificates.  Each FHLMC Certificate represents an undivided
interest in a pool of mortgage loans that may consist of first lien conventional
loans, FHA Loans or VA Loans (a "FHLMC Certificate Group"). FHLMC Certificates
are sold under the terms of a Mortgage Participation Certificate Agreement. A
FHLMC Certificate may be issued under either FHLMC's Cash Program or Guarantor
Program.
 
     Mortgage loans underlying the FHLMC Certificates held by a Trust Fund will
consist of mortgage loans with original terms to maturity of between 10 and 30
years. Each such mortgage loan must meet the applicable standards set forth in
the FHLMC Act. A FHLMC Certificate Group may include whole loans, participation
interests in whole loans and undivided interests in whole loans and/or
participations comprising another FHLMC Certificate Group. Under the Guarantor
Program, any such FHLMC Certificate Group may include only whole loans or
participation interests in whole loans.
 
     FHLMC guarantees to each registered holder of a FHLMC Certificate the
timely payment of interest on the underlying mortgage loans to the extent of the
applicable Certificate rate on the registered holder's pro rata share of the
unpaid principal balance outstanding on the underlying mortgage loans in the
FHLMC Certificate Group represented by such FHLMC Certificate, whether or not
received. FHLMC also guarantees to each registered holder of a FHLMC Certificate
collection by such holder of all principal on the underlying mortgage loans,
without any offset or deduction, to the extent of such holder's pro rata share
thereof, but does not, except if and to the extent specified in the related
Prospectus Supplement for a Series of Certificates, guarantee the timely payment
of scheduled principal. Under FHLMC's Gold PC Program, FHLMC guarantees the
timely payment of 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. 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 guaranty of collection of principal at
any time after default on an underlying mortgage loan, but not later than (i) 30
days following foreclosure sale, (ii) 30 days following payment of the claim by
any mortgage insurer or (iii) 30 days following 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 judgment with
respect to the mortgage loans in the same manner as for mortgage loans that it
has purchased but not sold. The length of time necessary for FHLMC to determine
that a mortgage loan should be accelerated varies with the particular
circumstances of each mortgagor, and FHLMC has not adopted standards which
require that the demand be made within any specified period.
 
                                       15
<PAGE>   134
 
     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, or entitled to,
the full faith and credit of the United States. If FHLMC were unable to satisfy
such obligations, distributions to Holders of FHLMC Certificates would consist
solely of payments and other recoveries on the underlying mortgage loans and,
accordingly, monthly distributions to holders of FHLMC Certificates would be
affected by delinquent payments and defaults on such mortgage loans.
 
     Registered holders of FHLMC Certificates are entitled to receive their
monthly pro rata share of all principal payments on the underlying mortgage
loans received by FHLMC, including any scheduled principal payments, full and
partial repayments of principal and principal received by FHLMC by virtue of
condemnation, insurance, liquidation or foreclosure, and repurchases of the
mortgage loans by FHLMC or the seller thereof. FHLMC is required to remit each
registered FHLMC certificateholder's pro rata share of principal payments on the
underlying mortgage loans, interest at the FHLMC pass-through rate and any other
sums such as prepayment fees, within 60 days of the date on which such payments
are deemed to have been received by FHLMC.
 
     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 pass-through rate on the FHLMC Certificate. Under such program, FHLMC
purchases groups of whole mortgage loans from sellers at specified percentages
of their unpaid principal balances, adjusted for accrued or prepaid interest,
which when applied to the interest rate of the mortgage loans and participations
purchased results in the yield (expressed as a percentage) required by FHLMC.
The required yield, which includes a minimum servicing fee retained by the
servicer, is calculated using the outstanding principal balance. The range of
interest rates on the mortgage loans and participations in a FHLMC Certificate
Group under the Cash Program will vary since mortgage loans and participations
are purchased and assigned to a FHLMC Certificate Group based upon their yield
to FHLMC rather than on the interest rate on the underlying mortgage loans.
Under FHLMC's Guarantor Program, the pass-through rate on a FHLMC Certificate is
established based upon the lowest interest rate on the underlying mortgage
loans, minus a minimum servicing fee and the amount of FHLMC's management and
guaranty income as agreed upon between the seller and FHLMC.
 
     FHLMC Certificates duly presented for registration of ownership on or
before the last business day of a month are registered effective as of the first
day of the month. The first remittance to a registered holder of a FHLMC
Certificate will be distributed so as to be received normally by the 15th day of
the second month following the month in which the purchaser became a registered
holder of the FHLMC Certificates. Thereafter, such remittance will be
distributed monthly to the registered holder so as to be received normally by
the 15th day of each month. The Federal Reserve Bank of New York maintains
book-entry accounts with respect to FHLMC Certificates sold by FHLMC on or after
January 2, 1985, and makes payments of principal and interest each month to the
registered holders thereof in accordance with such holders' instructions.
 
     Federal National Mortgage Association.  FNMA is a federally chartered and
privately owned corporation organized and existing under the Federal National
Mortgage Association Charter Act, as amended (the "Charter Act"). FNMA was
originally established in 1938 as a United States government agency to provide
supplemental liquidity to the mortgage market and was transformed into a
stockholder-owned and privately managed corporation by legislation enacted in
1968.
 
     FNMA provides funds to the mortgage market primarily by purchasing mortgage
loans from lenders, thereby replenishing their funds for additional lending.
FNMA acquires funds to purchase 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.
 
     FNMA Certificates.  FNMA Certificates are Guaranteed Mortgage Pass-Through
Certificates representing fractional undivided interests in a pool of mortgage
loans formed by FNMA. Each mortgage loan must meet the applicable standards of
the FNMA purchase program. Mortgage loans comprising a pool are
                                       16
<PAGE>   135
 
either provided by FNMA from its own portfolio or purchased pursuant to the
criteria of the FNMA purchase program.
 
     Mortgage loans underlying FNMA Certificates held by a Trust Fund will
consist of conventional mortgage loans, FHA Loans or VA Loans. Original
maturities of substantially all of the conventional, level payment mortgage
loans underlying a FNMA Certificate are expected to be between either 8 to 15
years or 20 to 30 years. The original maturities of substantially all of the
fixed rate level payment FHA Loans or VA Loans are expected to be 30 years.
 
     Mortgage loans underlying a FNMA Certificate may have annual interest rates
that vary by as much as two percentage points from each other. The rate of
interest payable on a FNMA Certificate is equal to the lowest interest rate of
any mortgage loan in the related pool, less a specified minimum annual
percentage representing servicing compensation and FNMA's guaranty fee. Under a
regular servicing option (pursuant to which the mortgagee or each other servicer
assumes the entire risk of foreclosure losses), the annual interest rates on the
mortgage loans underlying a FNMA Certificate will be between 50 basis points and
250 basis points greater than its annual pass-through rate and under a special
servicing option (pursuant to which FNMA assumes the entire risk for foreclosure
losses), the annual interest rates on the mortgage loans underlying a FNMA
Certificate will generally be between 55 basis points and 255 basis points
greater than the annual FNMA Certificate pass-through rate. If specified in the
related Prospectus Supplement, FNMA Certificates may be backed by adjustable
rate mortgages.
 
     FNMA guarantees to each registered holder of a FNMA Certificate that it
will distribute amounts representing such holder's proportionate share of
scheduled principal and interest payments at the applicable pass-through rate
provided for by such FNMA Certificate on the underlying mortgage loans, whether
or not received, and such holder's proportionate share of the full principal
amount of any foreclosed or other finally liquidated mortgage loan, whether or
not such principal amount is actually recovered. The obligations of FNMA under
its guarantees are obligations solely of FNMA and are not backed by, or entitled
to, the full faith and credit of the United States. Although the Secretary of
the Treasury of the United States has discretionary authority to lend FNMA up to
$2.25 billion outstanding at any time, neither the United States nor any agency
thereof is obligated to finance FNMA's operations or to assist FNMA in any other
manner. If FNMA were unable to satisfy its obligations, distributions to holders
of FNMA Certificates would consist solely of payments and other recoveries on
the underlying mortgage loans and, accordingly, monthly distributions to holders
of FNMA Certificates would be affected by delinquent payments and defaults on
such mortgage loans.
 
     FNMA Certificates evidencing interests in pools of mortgage loans formed on
or after May 1, 1985 (other than FNMA Certificates backed by pools containing
graduated payment mortgage loans or mortgage loans secured by multifamily
projects) are available in book-entry form only. Distributions of principal and
interest on each FNMA Certificate will be made by FNMA on the 25th day of each
month to the persons in whose name the FNMA Certificate is entered in the books
of the Federal Reserve Banks (or registered on the FNMA Certificate register in
the case of fully registered FNMA Certificates) as of the close of business on
the last day of the preceding month. With respect to FNMA Certificates issued in
book-entry form, distributions thereon will be made by wire, and with respect to
fully registered FNMA Certificates, distributions thereon will be made by check.
 
     As described above, the FNMA Certificates included in a Trust Fund, 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 Prospectus Supplement.
 
     Stripped Mortgage-Backed Securities.  Agency Securities may consist of one
or more stripped mortgage-backed securities, each as described herein and in the
related Prospectus Supplement. Each such Agency Security will represent an
undivided interest in all or part of either the principal distributions (but not
the interest distributions) or the interest distributions (but not the principal
distributions), or in some specified portion of the principal and interest
distributions (but not all of such distributions) on certain FHLMC, FNMA or GNMA
Certificates. The underlying securities will be held under a trust agreement by
FHLMC, FNMA or GNMA, each as trustee, or by another trustee named in the related
Prospectus Supplement.
                                       17
<PAGE>   136
 
FHLMC, FNMA or GNMA will guaranty each stripped Agency Security to the same
extent as such entity guarantees the underlying securities backing such stripped
Agency Security, unless otherwise specified in the related Prospectus
Supplement.
 
     Other Agency Securities.  If specified in the related Prospectus
Supplement, a Trust Fund may include other mortgage pass-through certificates
issued or guaranteed by GNMA, FNMA or FHLMC. The characteristics of any such
mortgage pass-through certificates will be described in such Prospectus
Supplement. If so specified, a combination of different types of Agency
Securities may be held in a Trust Fund.
 
PRIVATE MORTGAGE-BACKED SECURITIES
 
     General.  Private Mortgage-Backed Securities may consist of (a) mortgage
pass-through certificates or participation certificates evidencing an undivided
interest in a Mortgage Pool or (b) collateralized mortgage obligations secured
by Mortgage Loans. Private Mortgage-Backed Securities 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
specified portion of the principal and interest distributions (but not all of
such distributions) on certain Mortgage Loans. Private Mortgage-Backed
Securities will have been publicly issued pursuant to a pooling and servicing
agreement, an indenture or similar agreement (a "PMBS Agreement"). Unless
otherwise specified in the related Prospectus Supplement, the seller/servicer of
the underlying Mortgage Loans will have entered into the PMBS Agreement with the
trustee under such PMBS Agreement (the "PMBS Trustee"). The PMBS Trustee or its
agent, or a custodian, will possess the Mortgage Loans underlying such Private
Mortgage-Backed Securities. Mortgage Loans underlying a Private Mortgage-Backed
Security will be serviced by a servicer (the "PMBS Servicer") directly or by one
or more subservicers who may be subject to the supervision of the PMBS Servicer.
 
     The issuer of the Private Mortgage-Backed Securities (the "PMBS Issuer")
will be a financial institution or other entity engaged generally in the
business of mortgage lending, a public agency or instrumentality of a state,
local or federal government, or a limited purpose corporation organized for the
purpose of, among other things, establishing trusts and acquiring and selling
housing loans to such trusts and selling beneficial interests in such trusts. If
so specified in the related Prospectus Supplement, the PMBS Issuer may be an
affiliate of the Depositor. The obligations of the PMBS Issuer 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
Prospectus Supplement, the PMBS Issuer will not have guaranteed any of the
assets conveyed to the related trust or any of the Private Mortgage-Backed
Securities issued under the PMBS Agreement. Additionally, although the Mortgage
Loans underlying the Private Mortgage-Backed Securities may be guaranteed by an
agency or instrumentality of the United States, the Private Mortgage-Backed
Securities themselves will not be so guaranteed.
 
     Distributions of principal and interest will be made on the Private
Mortgage-Backed Securities on the dates specified in the related Prospectus
Supplement. The Private Mortgage-Backed Securities may be entitled to receive
nominal or no principal distributions or nominal or no interest distributions.
Principal and interest distributions will be made on the Private Mortgage-Backed
Securities by the PMBS Trustee or the PMBS Servicer. The PMBS Issuer or the PMBS
Servicer may have the right to repurchase assets underlying the Private
Mortgage-Backed Securities after a certain date or under other circumstances
specified in the related Prospectus Supplement.
 
     Underlying Loans.  The Mortgage Loans underlying the Private
Mortgage-Backed Securities may consist of fixed rate, level payment, fully
amortizing loans or graduated payment mortgage loans, Buydown Loans, adjustable
rate mortgage loans, or loans having balloon or other special payment features.
Such Mortgage Loans may be secured by single family property or by an assignment
of the proprietary lease or occupancy agreement relating to a specific dwelling
within a Cooperative and the related shares issued by such Cooperative.
 
                                       18

     Additional Information.  The Prospectus Supplement for a Series for which
the Trust Fund includes Private Mortgage-Backed Securities will specify, to the
extent known to the Depositor, (i) the aggregate approximate principal amount
and type of the Private Mortgage-Backed Securities to be included in the Trust
Fund, (ii) certain characteristics of the Mortgage Loans which comprise the
underlying assets for the Private Mortgage-Backed Securities including (A) the
payment features of such Mortgage Loans, (B) the approximate aggregate principal
balance of underlying Mortgage Loans insured or guaranteed by a governmental
entity, (C) the servicing fee or range of servicing fees with respect to the
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 Mortgage-Backed Securities, (iv) the
weighted average term-to-stated maturity of the Private Mortgage-Backed
Securities, (v) the pass-through or certificate rate of the Private
Mortgage-Backed Securities, (vi) the weighted average pass-through or
certificate rate of the Private Mortgage-Backed Securities, (vii) the PMBS
Issuer, the PMBS Servicer (if other than the PMBS Issuer) and the PMBS Trustee
for such Private Mortgage-Backed Securities, (viii) certain characteristics of
credit support, if any, such as reserve funds, insurance policies, surety bonds,
letters of credit or guaranties relating to the Mortgage Loans underlying the
Private Mortgage-Backed Securities or to such Private Mortgage-Backed Securities
themselves, (ix) the term on which the underlying Mortgage Loans for such
Private Mortgage-Backed Securities may, or are required to, be purchased prior
to their stated maturity or the stated maturity of the Private Mortgage-Backed
Securities and (x) the terms on which Mortgage Loans may be substituted for
those originally underlying the Private Mortgage-Backed Securities.
 
                        SUBSTITUTION OF MORTGAGE ASSETS
 
     Substitution of Mortgage Assets will be permitted in the event of breaches
of representations and warranties with respect to any original Mortgage Asset or
in the event the documentation with respect to any Mortgage Asset is determined
by the Trustee or a custodian appointed by the Trustee to be incomplete. The
period during which such substitution will be permitted generally will be
indicated in the related Prospectus Supplement. The related Prospectus
Supplement will describe any other conditions upon which Mortgage Assets may be
substituted for Mortgage Assets initially included in the Trust Fund.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the applicable Prospectus Supplement,
substantially all of the net proceeds from the sale of each Series of
Certificates will be used by the Depositor for the purchase of the Mortgage
Assets represented by the Certificates of such Series or to reimburse amounts
previously used to effect such a purchase, the costs of carrying the related
Mortgage Assets until the sale of the Certificates and other expenses connected
with pooling the related Mortgage Assets and issuing the Certificates. The
Depositor expects to sell Certificates in Series from time to time, but the
timing and amount of offerings of Certificates will depend on a number of
factors, including, among others, the volume of Mortgage Assets acquired by the
Depositor, prevailing interest rates, availability of funds and general market
conditions.
 
                                 THE DEPOSITOR
 
     First Union Residential Securitization Transactions, Inc. (the "Depositor")
was incorporated in the State of North Carolina on February 27, 1996, as a
wholly-owned, limited purpose subsidiary of First Union National Bank, a
national banking association (a subsidiary of First Union Corporation, a North
Carolina corporation). The Depositor maintains its principal executive office at
301 South College Street, Charlotte, North Carolina 28202-0600. Its telephone
number is (704) 383-3624.
 
     As described herein under "Mortgage Loan Program -- Representations by
Sellers; Repurchases," the only obligations, if any, of the Depositor with
respect to a Series of Certificates may be pursuant to certain limited
representations and warranties and limited undertakings to repurchase or
substitute Mortgage Loans under certain circumstances. The Depositor will have
no ongoing servicing obligations or responsibilities with
 
                                       19
<PAGE>   138
 
respect to any Mortgage Pool. The Depositor does not have, nor is it expected in
the future to have, any significant assets.
 
     As specified in the related Prospectus Supplement, the Master Servicer with
respect to any Series of Certificates evidencing interests in Mortgage Loans may
be an affiliate of the Depositor. As described under "The Trust Fund -- The
Mortgage Loans -- General," "-- Agency Securities" and "-- Private Mortgage-
Backed Securities," the Depositor anticipates that it will acquire Mortgage
Loans, Agency Securities and Private Mortgage-Backed Securities in the open
market or in privately negotiated transactions, which may be through or from an
affiliate.
 
     Neither the Depositor nor First Union Corporation nor any of its
affiliates, including First Union Capital Markets Corp. and First Union National
Bank, will insure or guarantee the Certificates of any Series.
 
                             MORTGAGE LOAN PROGRAM
 
     The Mortgage Loans will have been purchased by the Depositor, either
directly or through affiliates, from one or more Sellers, which may be
affiliates of the Depositor. Unless otherwise specified in the related
Prospectus Supplement, the Mortgage Loans so acquired by the Depositor will have
been originated in accordance with the underwriting criteria specified below
under "-- Underwriting Standards." See the Prospectus Supplement for each Series
of Certificates for a more detailed description of the mortgage loan program of
the Sellers.
 
UNDERWRITING STANDARDS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Seller will represent and warrant that all Mortgage Loans originated or acquired
by it and sold to the Depositor will have been underwritten in accordance with
standards consistent with those utilized by mortgage lenders generally during
the period of origination for similar types of loans. As to any Mortgage Loan
insured by the FHA or partially guaranteed by the VA, the Seller will represent
that it has complied with underwriting policies of the FHA or the VA, as the
case may be.
 
     Underwriting standards are applied by or on behalf of a lender to evaluate
the borrower's credit standing and repayment ability, and the value and adequacy
of the Mortgaged Property as collateral. In general, a prospective borrower
applying for a Mortgage Loan is required to fill out a detailed application
designed to provide to the underwriting officer pertinent credit information. As
part of the description of the borrower's financial condition, the borrower
generally is required to provide a current list of assets and liabilities and a
statement of income and expenses, as well as an authorization to apply for a
credit report which summarizes the borrower's credit history. In addition, an
employment verification may be requested from an independent source (typically
the borrower's employer) or, in lieu thereof, verbal verification is obtained if
the applicant has supplied a copy of a current pay stub along with personal tax
returns. In the case of Home Equity Loans, a pay stub is required of the
borrower and either independent employment verification, tax returns or verbal
confirmation of employment is obtained. Self-employed applicants typically
submit the last two years' employment history and business tax returns. Upon
receipt of the application package, a Seller usually conducts its own review of
the application package and may, in some instances, obtain additional
information concerning the prospective borrower prior to approving the loan.
Along with obtaining a credit report, such Seller may solicit a written
verification of the applicant's existing first mortgage balance, if any, and
payment history from the first mortgage lender, if appropriate. If such lender
does not respond in writing, verbal verification is attempted and the applicant
generally is required to submit the prior year's mortgage statements which
generally reflect a monthly payment history. In the case of those Home Equity
Loans which are subordinate to a first lien mortgage loan, the Seller also
obtains one of the following: (i) a credit report covering the preceding twelve
months, (ii) written or verbal verification of the applicant's first mortgage
balance, if any, (iii) written confirmation from a first mortgagee, if any, of
the prospective borrower's most recent twelve-month payment history, (iv)
canceled mortgage payment checks for the preceding twelve months, (v) a
combination of items from clauses (i) through (iv) above that establish a
payment

history on the first mortgage for the prior twelve months, or (vi) if the first
mortgage is privately held, twelve canceled payment checks and a copy of the
executed first mortgage note.
 
     In determining the adequacy of the Mortgaged Property as collateral, an
appraisal is made of each property considered for financing (except in the case
of low balance Home Equity Loans). The appraiser is required to inspect the
property and verify that it is in good repair and that construction, if new, has
been completed. The appraisal is based on the market value of comparable homes,
the estimated rental income (if considered applicable by the appraiser) and the
cost of replacing the home.
 
     Once all applicable employment, credit and property information is
received, a determination generally is made as to whether the prospective
borrower has sufficient monthly income available (i) to meet the borrower's
monthly obligations on the proposed mortgage loan, and on any senior mortgage
loan, in the case of a proposed Home Equity Loan (generally determined on the
basis of the monthly payments due in the year of origination), and other
expenses related to the Mortgaged Property (such as property taxes and hazard
insurance) and (ii) to meet monthly housing expenses and other financial
obligations and monthly living expenses. In connection with the origination of a
Mortgage Loan, the Seller evaluates each obligor's credit quality and assigns a
credit grade of A, B, C or D to each such borrower. Certain credit grades may
have sub-grades. The obligors of Home Equity Loans have generally been assigned
credit grades of A2 or lower. Mortgage Loans other than Home Equity Loans
generally have a credit grade of A. The underwriting standards applied by
Sellers, particularly with respect to the level of loan documentation and the
mortgagor's income and credit history, may be varied in appropriate cases where
factors such as low Loan-to-Value Ratios or other favorable credit exist.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Mortgage Loans are secured by a mortgage on property located in any of the 50
states or the District of Columbia. Mortgage Loans may be secured by leases on
real property under guidelines that a Seller determines in its discretion are
acceptable to institutional mortgage investors. Generally, a loan will be
secured by a lease only if the use of leasehold estates as security for mortgage
loans is common and customary in the area, the lease is not subject to any prior
lien that could result in termination of the lease and the term of the lease
ends five years beyond the maturity date of the related Mortgage Loan.
 
     Unless otherwise provided in the applicable Prospectus Supplement, all
Mortgage Loans will be covered by an appropriate standard form American Land
Title Association ("ALTA") title insurance policy, or a substantially similar
policy or form of insurance acceptable to the Federal National Mortgage
Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC"), or
an attorney's title opinion.
 
     If so specified in the applicable Prospectus Supplement, Mortgage Loans may
be subject to temporary interest subsidy agreements ("Subsidy Loans") pursuant
to which the monthly payments made by the related mortgagors will be less than
the scheduled monthly payments on such Mortgage Loans with the present value of
the resulting difference in payment ("Subsidy Payments") being provided by the
employer of the mortgagor generally on an annual basis. Unless otherwise
specified in the applicable Prospectus Supplement, Subsidy Payments will be
placed in a custodial account ("Subsidy Account") by the Servicer. Despite the
existence of a subsidy program, a mortgagor remains primarily liable for making
all scheduled payments on a Subsidy Loan and for all other obligations provided
for in the related Mortgage Note and Mortgage Loan.
 
     If so specified in the applicable Prospectus Supplement, the Trust Fund may
contain Mortgage Loans subject to temporary Buydown Loans pursuant to which the
monthly payments made by the mortgagor during the early years of the Mortgage
Loan will be less than the scheduled monthly payments on the Mortgage Loan. The
resulting difference in payment will be compensated for from an amount
contributed by the seller of the related Mortgaged Property or another source,
including the originator of the Mortgage Loan (generally on a present value
basis) and, if so specified in the related Prospectus Supplement, placed in a
Buydown Fund by the Master Servicer.
 
     If so specified in the applicable Prospectus Supplement, the Trust Fund may
include Mortgage Loans which are amortized over 30 years but which have shorter
terms to maturity (each such Mortgage Loan, a "Balloon Loan") that causes the
outstanding principal balance of the related Mortgage Loan to be due and
 
                                       21
<PAGE>   140
 
payable at the end of a certain specified period (the "Balloon Period"). Unless
otherwise specified in the applicable Prospectus Supplement, the borrower of
such Balloon Loan will be obligated to pay the entire outstanding principal
balance of the Balloon Loan at the end of the related Balloon Period.
 
     Certain of the types of Mortgage Loans that may be included in a Trust Fund
are recently developed and may involve additional uncertainties not present in
traditional types of loans. For example, certain of such Mortgage Loans may
provide for escalating or variable payments by the mortgagor or obligor. These
types of Mortgage Loans are underwritten on the basis of a judgment that
mortgagors or obligors will have the ability to make monthly payments required
initially. In some instances, however, a mortgagor's or obligor's income may not
be sufficient to permit continued loan payments as such payments increase. These
types of Mortgage Loans may also be underwritten primarily upon the basis of
Loan-to-Value Ratios or other favorable credit factors.
 
QUALIFICATIONS OF SELLERS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Seller will be required to satisfy the qualifications set forth herein. Each
Seller must be an institution experienced in originating and servicing Mortgage
Loans of the type contained in the related Mortgage Pool in accordance with
accepted practices and prudent guidelines, and must maintain satisfactory
facilities to originate and service those Mortgage Loans. Each Seller must be a
seller/servicer approved by either FNMA or FHLMC. Each Seller must be a
mortgagee approved by the FHA or an institution the deposit accounts in which
are insured by the Federal Deposit Insurance Corporation (the "FDIC").
 
REPRESENTATIONS BY SELLERS; REPURCHASES
 
     Each Seller will have made representations and warranties in respect of the
Mortgage Loans sold by such Seller and evidenced by a Series of Certificates.
Such representations and warranties unless otherwise provided in the related
Prospectus Supplement generally include, among other things, that (i)
immediately prior to the transfer and assignment of the Mortgage Loans, the
seller had good title to, and was the sole owner of, each Mortgage Loan and
there had been no other sale or assignment thereof, (ii) as of the date of such
transfer, the Mortgage Loans are subject to no offsets, defenses or
counterclaims, (iii) each Mortgage Loan at the time it was made complied in all
material respects with applicable state and federal laws, including usury, equal
credit opportunity and disclosure laws, (iv) a lender's policy of title
insurance or an attorney's title opinion was issued on the date of the
origination of each Mortgage Loan and each such policy is valid and remains in
full force and effect, (v) as of the date of such transfer, each Mortgage
subject to the Agreement is a valid lien on the related Mortgaged Property
(subject only to (a) permitted senior liens on such Mortgaged Property and (b)
the exceptions to title set forth in the related title insurance policy or
attorney's opinion, which exceptions are generally acceptable to mortgage
lending companies, and such other exceptions to which similar properties are
commonly subject and which do not individually, or in the aggregate, materially
and adversely affect the benefits of the security intended to be provided by
such Mortgage), and to the best knowledge of the Seller, such property is free
of material damage and is in good repair, (vi) as of the date of such transfer,
no Mortgage Loan is more than 30 days delinquent in payment and there are no
delinquent tax or assessment liens against the related Mortgaged Property, and
(vii) with respect to each Mortgage Loan, if the Mortgaged Property is located
in an area identified by the Federal Emergency Management Agency as having
special flood hazards and subject in certain circumstances to the availability
of flood insurance under the National Flood Insurance Act of 1968, as amended,
such Mortgaged Property is covered by flood insurance.
 
     If so specified in the related Prospectus Supplement, the representations
and warranties of a Seller in respect of a Mortgage Loan will be made not as of
the Cut-off Date but as of the date on which such Seller sold the Mortgage Loan
to the Depositor or one of its affiliates. Under such circumstances, a
substantial period of time may have elapsed between such date and the date of
initial issuance of the Series of Certificates evidencing an interest in such
Mortgage Loan. Since the representations and warranties of a Seller do not
address events that may occur following the sale of a Mortgage Loan by such
Seller, its repurchase obligation described below will not arise if the relevant
event that would otherwise have given rise to such an obligation
                                       22
<PAGE>   141
 
with respect to a Mortgage Loan occurs after the date of sale of such Mortgage
Loan by such Seller to the Depositor or its affiliates. If the Master Servicer
is also a Seller of Mortgage Loans with respect to a particular Series, such
representations will be in addition to the representations and warranties made
by the Master Servicer in its capacity as a Master Servicer.
 
     The Master Servicer or the Trustee, if the Master Servicer is the Seller,
will promptly notify the relevant Seller of any breach of any representation or
warranty made by it in respect of a Mortgage Loan which materially and adversely
affects the interests of the Certificateholders in such Mortgage Loan. Unless
otherwise specified in the related Prospectus Supplement, if such Seller cannot
cure such breach within 90 days after notice from the Master Servicer or the
Trustee, as the case may be, then such Seller will be obligated to repurchase
such Mortgage Loan from the Trust Fund at a price (the "Purchase Price") equal
to 100% of the Principal Balance thereof as of the date of the repurchase plus
accrued interest thereon to the first day of the month in which the Purchase
Price is to be distributed at the Mortgage Rate (less any unreimbursed Advances
or amount payable as related servicing compensation if the Seller is the Master
Servicer with respect to such Mortgage Loan). If a REMIC election is to be made
with respect to a Trust Fund, unless otherwise provided in the related
Prospectus Supplement, holders of Subordinated Certificates or a holder of the
related residual certificate will be obligated to pay any prohibited transaction
tax which may arise in connection with any such repurchase. If the Master
Servicer advances any such payment, it will be entitled to reimbursement from
the assets of the related Trust Fund or from any holder of the related residual
certificate, unless otherwise specified in the related Prospectus Supplement.
See "Description of the Certificates -- General." Except in those cases in which
the Master Servicer is the Seller, the Master Servicer will be required under
the applicable Agreement to enforce this obligation for the benefit of the
Trustee and the holders of the Certificates, following the practices it would
employ in its good faith business judgment were it the owner of such Mortgage
Loan. This repurchase obligation will constitute the sole remedy available to
holders of Certificates or the Trustee for a breach of representation by a
Seller.
 
     Neither the Depositor nor the Master Servicer (unless the Master Servicer
is the Seller) will be obligated to purchase a Mortgage Loan if a Seller
defaults on its obligation to do so, and no assurance can be given that Sellers
will carry out their respective repurchase obligations with respect to Mortgage
Loans.
 
                        DESCRIPTION OF THE CERTIFICATES
 
     Each Series of Certificates will be issued pursuant to an Agreement, dated
as of the related Cut-off Date, among the Depositor, the Master Servicer and the
Trustee for the benefit of the holders of the Certificates of such Series. The
provisions of each Agreement will vary depending upon the nature of the
Certificates to be issued thereunder and the nature of the related Trust Fund.
Forms of Agreements are exhibits to the Registration Statement of which this
Prospectus is a part. The following summaries describe certain provisions that
may appear in each Agreement. The Prospectus 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
Agreement for each Series of Certificates and the applicable Prospectus
Supplement. The Depositor will provide a copy of the Agreement (without
exhibits) relating to any Series without charge upon written request of a holder
of record of a Certificate of such Series addressed to First Union Residential
Securitization Transactions, Inc., 301 South College Street, Charlotte, North
Carolina 28288-0600.
 
GENERAL
 
     Unless otherwise specified in the Prospectus Supplement, the Certificates
of each Series will be issued in either fully registered or book-entry form, in
the authorized denominations specified in the related Prospectus Supplement,
will evidence specified beneficial ownership interests in the related Trust Fund
created pursuant to each Agreement and will not be entitled to payments in
respect of the assets included in any other Trust Fund established by the
Depositor. The Certificates will not represent obligations of the Depositor or
any affiliate of the Depositor. The Mortgage Loans will not be insured or
guaranteed by any governmental entity or
 
                                       23
<PAGE>   142
 
other person, unless otherwise specified in the related Prospectus Supplement.
Each Trust Fund will consist of, to the extent provided in the Agreement, (i)
the Mortgage Assets, that from time to time are subject to the related Agreement
(exclusive of any amounts specified in the related Prospectus Supplement
("Retained Interest")); (ii) such assets as from time to time are required to be
deposited in the related Collection Account, as defined below under "The Pooling
and Servicing Agreement -- Payments on Mortgage Loans; Deposits to Collection
Account"; (iii) property which secured a Mortgage Loan and which is acquired on
behalf of the Certificateholders by foreclosure or deed in lieu of foreclosure;
and (iv) any Primary Mortgage Insurance Policies, FHA Insurance and VA
Guarantees, and any other insurance policies or other forms of credit
enhancement required to be maintained pursuant to the Agreement. If so specified
in the related Prospectus Supplement, a Trust Fund may also include one or more
of the following: reinvestment income on payments received on the Mortgage
Assets, a reserve fund, a mortgage pool insurance policy, a special hazard
insurance policy, a bankruptcy bond, one or more letters of credit, a surety
bond, guaranties or similar instruments or other agreements.
 
     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 Trust Fund. A Series of
Certificates may include one or more classes that are senior or subordinate 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 enhancement, in each case as described
herein and in the related Prospectus Supplement. One or more classes of
Certificates of a Series may be entitled to receive principal distributions,
with disproportionate, nominal or no interest distributions or to interest
distributions, with disproportionate, nominal or no principal distributions or
any combination thereof. Distributions on one or more 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 Trust Fund, or on a different basis, in each case as specified in the
related Prospectus Supplement. The timing, amounts, sequential order and
priority of payment of such distributions may vary among classes or over time as
specified in the related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement,
distributions of principal and interest (or, where applicable, of principal only
or interest only) on the related Certificates will be made by the Trustee on
each Distribution Date (i.e., monthly, quarterly, semi-annually or at such other
intervals and on the dates as are specified in the Prospectus Supplement) in
proportion to the percentages specified in the related Prospectus Supplement.
Distributions will be made to the persons in whose names the Certificates are
registered at the close of business on the dates specified in the related
Prospectus Supplement (each, a "Record Date"). Distributions will be made by
check or money order mailed to the persons entitled thereto at the address
appearing in the register maintained for holders of Certificates (the
"Certificate Register") or, if specified in the related Prospectus Supplement,
in the case of Certificates that are of a certain minimum denomination, upon
written request by the Certificateholder, by wire transfer or by such other
means as are described therein; provided, however, that the final distribution
in retirement of the Certificates will be made only upon presentation and
surrender of the Certificates at the office or agency of the Trustee or other
person specified in the notice to Certificateholders of such final distribution.
 
     The Certificates will be freely transferable and exchangeable at the
Corporate Trust Office of the Trustee as set forth in the related Prospectus
Supplement. No service charge will be made for any registration of exchange or
transfer of Certificates of any Series but the Trustee may require payment of a
sum sufficient to cover any related tax or other governmental charge.
 
     Under current law the purchase and holding by or on behalf of any employee
benefit plan or other retirement arrangement (including individual retirement
accounts and annuities, Keogh plans and collective investment funds in which
such plans, accounts or arrangements are invested) subject to provisions of
ERISA or the Code of a class of Certificates entitled only to a specified
percentage of payments of either interest or principal or a notional amount of
either interest or principal on the related Mortgage Loans or a class of
Certificates entitled to receive payments of interest and principal on the
Mortgage Loans only after payments
                                       24
<PAGE>   143
 
to other classes or after the occurrence of certain specified events may result
in "prohibited transactions" within the meaning of ERISA and the Code. See
"ERISA Considerations." Unless otherwise specified in the related Prospectus
Supplement, transfer of Certificates of such a class will not be registered
unless the transferee (i) represents that it is not, and is not purchasing on
behalf of, any such plan, account or arrangement or (ii) provides an opinion of
counsel satisfactory to the Trustee and the Depositor that the purchase of
Certificates of such a class by or on behalf of such plan, account or
arrangement is permissible under applicable law and will not subject the
Trustee, the Master Servicer or the Depositor to any obligation or liability in
addition to those undertaken in the Agreement.
 
     As to each Series, an election may be made to treat the related Trust Fund
or designated portions thereof as one or more "real estate mortgage investment
conduits" (each, a "REMIC") as defined in the Code. The related Prospectus
Supplement will specify whether a REMIC election is to be made. Alternatively,
the Agreement for a Series may provide that a REMIC election may be made at the
discretion of the Depositor or the Seller and may be made only if certain
conditions are satisfied. As to any such Series, the terms and provisions
applicable to the making of a REMIC election, as well as any material federal
income tax consequences to Certificateholders not otherwise described herein,
will be set forth in the related Prospectus Supplement. If such an election is
made with respect to a Series, one of the classes will be designated as
evidencing the sole class of "residual interests" in the related REMIC, as
defined in the Code. All other classes of Certificates in such a Series will
constitute "regular interests" in the related REMIC, as defined in the Code. As
to each Series with respect to which a REMIC election is to be made, holders of
Subordinated Certificates or a holder of the related residual certificate will
be obligated to take all actions required in order to comply with applicable
laws and regulations and will be obligated to pay any prohibited transaction
taxes. The Master Servicer, unless otherwise specified in the related Prospectus
Supplement, will be entitled to reimbursement for any such payment from the
assets of the Trust Fund or from any holder of the related residual certificate.
 
     Unless otherwise specified in the related Prospectus Supplement, upon the
conversion of such Mortgage Loan from an adjustable interest rate to a fixed
interest rate, the Seller or its successor will be obligated to purchase such
related Mortgage Loan from the related Trust Fund.
 
DISTRIBUTIONS ON CERTIFICATES
 
     General.  In general, the method of determining the amount of distributions
on a particular Series of Certificates will depend on the type of credit
support, if any, that is used with respect to such Series. See "Credit
Enhancement." Set forth below are descriptions of various methods that may be
used to determine the amount of distributions on the Certificates of a
particular Series. The Prospectus Supplement for each Series of Certificates
will describe the method to be used in determining the amount of distributions
on the Certificates of such Series. Distributions allocable to principal of and
interest on the Certificates will be made by the Trustee out of, and only to the
extent of, funds in the related Collection Account, including any funds
transferred from any Reserve Fund. As between Certificates of different classes
and as between distributions of principal (and, if applicable, between
distributions of Principal Prepayments, as defined below, and scheduled payments
of principal) and interest, distributions made on any Distribution Date will be
applied as specified in the related Prospectus Supplement. Unless otherwise
specified in the related Prospectus Supplement, distributions to any class of
Certificates will be made pro rata to all Certificateholders of that class.
 
     Available Distribution Amount.  Unless otherwise specified in the related
Prospectus Supplement, all distributions on the Certificates of each Series on
each Distribution Date will be made from the Available Distribution Amount
described below, in accordance with the terms described in the related
Prospectus Supplement and specified in the Agreement. Unless otherwise provided
in the related Prospectus Supplement, the "Available Distribution Amount" for
each Distribution Date will equal the sum of the following amounts:
 
          (i) the aggregate of all previously undistributed payments on account
     of principal (including Principal Prepayments, if any, and prepayment
     penalties, if so provided in the related Prospectus Supplement) and
     interest on the Mortgage Loans in the related Trust Fund (including
     Liquidation
 
                                       25
<PAGE>   144
 
     Proceeds and Insurance Proceeds and amounts drawn under letters of credit
     or other credit enhancement instruments as permitted thereunder and as
     specified in the related Agreement) received by the Servicer after the
     Cut-off Date and on or prior to the day of the month of the related
     Distribution Date specified in the related Prospectus Supplement (the
     "Determination Date") except:
 
             (a) all payments that were due on or before the Cut-off Date;
 
             (b) all Liquidation Proceeds and all Insurance Proceeds, all
        Principal Prepayments and all other proceeds of any Mortgage Loan
        purchased by the Depositor, any Sub-Servicer or any Seller pursuant to
        the Agreement that were received after the prepayment period specified
        in the related Prospectus Supplement and all related payments of
        interest representing interest for any period after such prepayment
        period;
 
             (c) all scheduled payments of principal and interest due on a date
        or dates subsequent to the first day of the month of distribution;
 
             (d) amounts received on particular Mortgage Loans as late payments
        of principal or interest or other amounts required to be paid by
        Mortgagors, but only to the extent of any unreimbursed advance in
        respect thereof made by the Master Servicer (including the related
        Sub-Servicers);
 
             (e) amounts representing reimbursement, to the extent permitted by
        the Agreement and as described under "-- Advances" below, for advances
        made by the Master Servicer or Sub-Servicers that were deposited into
        the Collection Account, and amounts representing reimbursement for
        certain other losses and expenses incurred by the Master Servicer or the
        Depositor and described below;
 
             (f) that portion of each collection of interest on a particular
        Mortgage Loan in such Trust Fund that represents credit enhancement fees
        or servicing compensation payable to the Master Servicer or any
        Sub-Servicer or Retained Interest that is to be retained from such
        collection or is permitted to be retained from related Insurance
        Proceeds, Liquidation Proceeds or proceeds of Mortgage Loans purchased
        pursuant to the Agreement;
 
          (ii) the amount of any advance made by the Master Servicer or
     Sub-Servicer as described under "-- Advances" below and deposited by it in
     the Collection Account; and
 
          (iii) if applicable, amounts withdrawn from a Reserve Fund.
 
     Distributions of Interest.  Unless otherwise specified in the related
Prospectus Supplement, interest will accrue on the aggregate Certificate Balance
(or, in the case of Certificates entitled only to distributions allocable to
interest, the aggregate notional amount) of each class of Certificates entitled
to interest at the Pass-Through Rate (which may be a fixed rate or rate
adjustable as specified in such Prospectus Supplement) from the date, and for
the periods, specified in such Prospectus Supplement. To the extent funds are
available therefor, interest accrued during each such specified period on each
class of 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 Prospectus Supplement until the
aggregate Certificate Balance of the Certificates of such class has been
distributed in full 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 Prospectus Supplement. The original Certificate Balance of each
Certificate will equal the aggregate distributions allocable to principal to
which such Certificate is entitled. Unless otherwise specified in the related
Prospectus Supplement, distributions allocable to interest on each Certificate
that is not entitled to distributions allocable to principal will be calculated
based on the notional amount of such Certificate. The notional amount of a
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.
 
     With respect to any class of Accrual Certificates, if specified in the
related Prospectus Supplement, any interest that has accrued but is not paid on
a given Distribution Date will be added to the aggregate Certificate
                                       26
<PAGE>   145
 
Balance of such class of Certificates on that Distribution Date. Unless
otherwise specified in the related Prospectus Supplement, distributions of
interest on each class of Accrual Certificates will commence only after the
occurrence of the events specified in such Prospectus Supplement. Unless
otherwise specified in the related Prospectus Supplement, prior to such time,
the beneficial ownership interest of such class of Accrual Certificates in the
Trust Fund, as reflected in the aggregate Certificate Balance of such class of
Accrual Certificates, will increase on each Distribution Date by the amount of
interest that accrued on such class of Accrual Certificates during the preceding
interest accrual period but that was not required to be distributed to such
class on such Distribution Date. Any such class of Accrual Certificates will
thereafter accrue interest on its outstanding Certificate Balance as so
adjusted.
 
     Distributions of Principal.  Unless otherwise specified in the related
Prospectus Supplement, the aggregate "Certificate Balance" of any class of
Certificates entitled to distributions of principal will be the aggregate
original Certificate Balance of such class of Certificates specified in such
Prospectus Supplement, reduced by all distributions reported to the holders of
such Certificates as allocable to principal and (i) in the case of Accrual
Certificates, if so specified in the related Prospectus Supplement, increased by
all interest accrued but not then distributable on such Accrual Certificates and
(ii) in the case of adjustable rate Certificates, if so specified in the related
Prospectus Supplement, subject to the effect of negative amortization. The
related Prospectus 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. A class of
interest-only Certificates will not be entitled to distributions of principal
and will have a notional principal balance on which interest will accrue.
 
     If so provided in the related Prospectus Supplement, one or more classes of
Senior Certificates will be entitled to receive all or a disproportionate
percentage of the payments of principal that are received from borrowers in
advance of their scheduled due dates and are not accompanied by amounts
representing scheduled interest due after the month of such payments ("Principal
Prepayments") in the percentages and under the circumstances or for the periods
specified in such Prospectus Supplement. Any such allocation of Principal
Prepayments to such class or classes of Certificateholders will have the effect
of accelerating the amortization of such Senior Certificates while increasing
the interests evidenced by the Subordinated Certificates in the Trust Fund.
Increasing the interests of the Subordinated Certificates relative to that of
the Senior Certificates is intended to preserve the availability of the
subordination provided by the Subordinated Certificates. See "Credit
Enhancement -- Subordination."
 
     Unscheduled Distributions.  To the extent specified in the related
Prospectus Supplement relating to a Series of Certificates which have less
frequent than monthly Distribution Dates, the Certificates will be subject to
receipt of distributions before the next scheduled Distribution Date under the
circumstances and in the manner described below and in such Prospectus
Supplement. If applicable, the Trustee will be required to make such unscheduled
distributions on the day and in the amount specified in the related Prospectus
Supplement if, due to substantial payments of principal (including Principal
Prepayments) on the Mortgage Assets, the Trustee or the Master Servicer
determines that the funds available or anticipated to be available from the
Collection Account and, if applicable, any Reserve Fund, may be insufficient to
make required distributions on the Certificates on such Distribution Date.
Unless otherwise specified in the related Prospectus Supplement, the amount of
any such unscheduled distribution that is allocable to principal will not exceed
the amount that would otherwise have been required to be distributed as
principal on the Certificates on the next Distribution Date. Unless otherwise
specified in the related Prospectus Supplement, all unscheduled distributions
will include interest at the applicable Pass-Through Rate (if any) on the amount
of the unscheduled distribution allocable to principal for the period and to the
date specified in such Prospectus Supplement. See "Yield and Prepayment
Considerations."
 
     Unless otherwise specified in the related Prospectus Supplement, all
distributions allocable to principal in any unscheduled distribution will be
made in the same priority and manner as distributions of principal on the
Certificates would have been made on the next Distribution Date, and with
respect to Certificates of the same class, unscheduled distributions of
principal will be made on a pro rata basis.
 
                                       27

     Notice of any unscheduled distribution will be given by the Trustee prior
to the date of such distribution.
 
ADVANCES
 
     Generally, the Master Servicer will be required to advance on or before
each Distribution Date (from its own funds, funds advanced by Sub-Servicers or
funds held in the Collection Account for future distributions to the holders of
such Certificates), an amount equal to the aggregate of payments of principal
and interest (or, in the case of Home Equity Loans, payments of interest only)
that were delinquent on the related Determination Date, subject to the Master
Servicer's determination that such advances will be recoverable out of late
payments by Mortgagors, Liquidation Proceeds, Insurance Proceeds or otherwise,
and net of applicable servicing compensation. In the case of Cooperative Loans,
the Master Servicer also will be required to advance any unpaid maintenance fees
and other charges under the related proprietary leases as specified in the
related Prospectus Supplement. The Prospectus Supplement for a Series of
Certificates will specify the nature and timing of amounts to be advanced to the
holders of such Certificates and the manner in which Advances may be recovered
by the Master Servicer. Funds so advanced are reimbursable to the Master
Servicer to the extent permitted by the related Agreement. The Master Servicer's
obligation to make Advances will not guarantee or insure against losses to
holders of the Certificates.
 
REPORTS TO CERTIFICATEHOLDERS
 
     Prior to or concurrently with each distribution on a Distribution Date and
except as otherwise set forth in an applicable Prospectus Supplement, the Master
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 Prospectus Supplement, prepayment penalties
     included therein;
 
          (ii) the amount of such distribution allocable to interest;
 
          (iii) the amount of any Advance;
 
          (iv) the outstanding Certificate Balance or notional amount of each
     class of the related Series after giving effect to the distribution of
     principal on such Distribution Date;
 
          (v) the related amount of the servicing compensation retained or
     withdrawn from the Collection Account by the Master Servicer;
 
          (vi) the number and aggregate principal balances of Mortgage Loans (A)
     delinquent (exclusive of Mortgage Loans in foreclosure) and (B) in
     foreclosure as of the close of business on the last day of the calendar
     month preceding such Distribution Date;
 
          (vii) the book value of any real estate acquired through foreclosure
     or grant of a deed in lieu of foreclosure;
 
          (viii) if applicable, the amount remaining in any Reserve Fund at the
     close of business on the Distribution Date;
 
          (ix) the Pass-Through Rate as of the day prior to the immediately
     preceding Distribution Date; and
 
          (x) any amounts remaining under letters of credit, pool policies or
     other forms of credit enhancement.
 
     Where applicable, any amount set forth above may be expressed as a dollar
amount per single Certificate of the relevant class having the Percentage
Interest specified in the related Prospectus Supplement. The report to
Certificateholders for any Series of Certificates may include additional or
other information of a similar nature to that specified above.
 
                                       28
<PAGE>   147
 
     In addition, within a reasonable period of time after the end of each
calendar year, the Master Servicer or the Trustee will mail to each
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.
 
BOOK-ENTRY REGISTRATION
 
     If so specified in the related Prospectus Supplement, a class of
Certificates may be book-entry Certificates (the "Book-Entry Certificates").
Persons acquiring beneficial ownership interests in such Certificates
("Certificate Owners") will hold their Certificates through the Depository Trust
Company ("DTC") in the United States, or Cedel Bank, societe anonyme ("CEDEL")
or the Euroclear System ("Euroclear") in Europe if they are participants of such
systems, or indirectly through organizations which are participants in such
systems (each, a "Participant"). The Book-Entry Certificates will be issued in
one or more certificates which equal the aggregate principal balance of such
class of Certificates and will initially be registered in the name of Cede & Co.
("Cede"), the nominee of DTC. CEDEL and Euroclear will hold omnibus positions on
behalf of their participants through customers' securities accounts in CEDEL's
and Euroclear's names on the books of their respective depositories, which in
turn will hold such positions in customers' securities accounts in the
depositories' names on the books of DTC. Citibank N.A. will act as depository
for CEDEL, and Morgan Guaranty Trust Company of New York ("Morgan") will act as
depository for Euroclear (in such capacities, individually the "Relevant
Depository" and collectively, the "European Depositories"). Except as described
below, no person acquiring a Book-Entry Certificate (each, a "beneficial owner")
will be entitled to receive a physical certificate representing such Certificate
(a "Definitive Certificate"). Unless and until Definitive Certificates are
issued, it is anticipated that the only "Certificateholder" of such Certificates
will be Cede, as nominee of DTC. Certificate Owners will not be
Certificateholders as that term is used in the Agreement. Certificate Owners are
only permitted to exercise their rights indirectly through Participants and DTC.
 
     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 DTC (or of a participating firm that acts as agent for the Financial
Intermediary, whose interest will in turn be recorded on the records of DTC, if
the beneficial owner's Financial Intermediary is not a DTC participant, and on
the records of CEDEL or Euroclear, as appropriate).
 
     Certificate Owners of a class of Book-Entry Certificates will receive all
distributions of principal of, and interest on, such Certificates from the
Trustee through DTC and DTC participants. While such Certificates are
outstanding (except under the circumstances described below), under the rules,
regulations and procedures creating and affecting DTC and its operations (the
"Rules"), DTC is required to make book-entry transfers among participants on
whose behalf it acts with respect to such class of Certificates and is required
to receive and transmit distributions of principal of, and interest on, such
Certificates. Participants and indirect participants with whom Certificate
Owners have accounts with respect to such Certificates are similarly required to
make book-entry transfers and receive and transmit such distributions on behalf
of their respective Certificate Owners. Accordingly, although Certificate Owners
will not possess certificates, the Rules provide a mechanism by which
Certificate Owners will receive distributions and will be able to transfer their
interest.
 
     Certificate Owners will not receive or be entitled to receive certificates
representing their respective interests in such Certificates, except under the
limited circumstances described below. Unless and until Definitive Certificates
are issued, Certificate Owners who are not Participants may transfer ownership
of such Certificates only through Participants and indirect participants by
instructing such Participants and indirect participants to transfer such
Certificates, by book-entry transfer, through DTC for the account of the
purchasers of such Certificates, which account is maintained with their
respective Participants. Under the Rules and in accordance with DTC's normal
procedures, transfers of ownership of a class of Book-Entry
                                       29
<PAGE>   148
 
Certificates will be executed through DTC, and the accounts of the respective
Participants at DTC will be debited and credited. Similarly, the Participants
and indirect participants will make debits or credits, as the case may be, on
their records on behalf of the selling and purchasing Certificate Owners.
 
     Because of time zone differences, credits of securities received in CEDEL
or Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
CEDEL Participants on such business day. Cash received in CEDEL or Euroclear as
a result of sales of securities by or through a CEDEL participant (as defined
below) or Euroclear Participant (as defined below) to a DTC Participant will be
received with value on the DTC settlement date but will be available in the
relevant CEDEL or Euroclear cash account only as of the business day following
settlement in DTC. For information with respect to tax documentation procedures
relating to the Certificates, see "Certain Federal Income Tax Consequences --
Non-U.S. Persons" and "-- Information Reporting and Backup Withholding" herein
and "Global Clearance, Settlement and Tax Documentation Procedures -- Certain
U.S. Federal Income Tax Documentation Requirements" in Annex I hereto.
 
     Transfers between Participants will occur in accordance with DTC rules.
Transfers between CEDEL Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through CEDEL
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depository; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time).
 
     The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depository to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. CEDEL Participants and Euroclear Participants may not deliver instructions
directly to the European Depositories.
 
     DTC, which is a New York-chartered limited purpose trust company, performs
services for its participants, some of which (and/or their representatives) own
DTC. In accordance with its normal procedures, DTC is expected to record the
positions held by each DTC 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 DTC and DTC participants as in effect from
time to time.
 
     CEDEL is incorporated under the laws of Luxembourg as a professional
depository. CEDEL holds securities for its participating organizations ("CEDEL
Participants") and facilitates the clearance and settlement of securities
transactions between CEDEL participants through electronic book-entry changes in
accounts of CEDEL Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in CEDEL in any of 28
currencies, including United States dollars. CEDEL provides to its CEDEL
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. CEDEL interfaces with domestic markets in several
countries. As a professional depository, CEDEL is subject to regulation by the
Luxembourg Monetary Institute. CEDEL participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to CEDEL is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a CEDEL participant, either directly or indirectly.
 
                                       30
<PAGE>   149
 
     Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium, office of
Morgan (the "Euroclear Operator"), under contract with Euroclear Clearance
Systems S.C., a Belgian cooperative corporation (the "Cooperative"). All
operations are conducted by the Euroclear Operator, and all Euroclear securities
clearance accounts and Euroclear cash accounts are accounts with the Euroclear
Operator, not the Cooperative. The Cooperative establishes policy for Euroclear
on behalf of Euroclear Participants. Euroclear Participants include banks
(including central banks), securities brokers and dealers and other professional
financial intermediaries. Indirect access to Euroclear is also available to
other firms that clear through or maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.
 
     The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.
 
     Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.
 
     Distributions on the Book-Entry Certificates will be made on each
Distribution Date by the Trustee to DTC. DTC will be responsible for crediting
the amount of such payments to the accounts of the applicable DTC Participants
in accordance with DTC's normal procedures. Each DTC 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. Distributions with respect to Certificates
held through CEDEL or Euroclear will be credited to cash accounts of CEDEL
Participants or Euroclear Participants in accordance with the relevant system's
rules and procedures, to the extent received by the Relevant Depository. Such
distributions will be subject to tax reporting in accordance with relevant
United States tax laws and regulations. See "Certain Federal Income Tax
Consequences -- Non-U.S. Persons" and " -- Information Reporting and Backup
Withholding" herein. Because DTC 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.
 
     Monthly and annual reports on the Trust Fund will be provided to Cede, as
nominee of DTC, and may be made available by Cede to beneficial owners upon
request, in accordance with the rules, regulations and procedures creating and
affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Certificates of such beneficial owners are credited.
 
                                       31
<PAGE>   150
 
     With respect to each class of Book-Entry Certificates, DTC will advise the
Trustee that, unless and until Definitive Certificates are issued, DTC will take
any action permitted to be taken by the holders of such Book-Entry Certificates
under the related Agreement only at the direction of one or more Financial
Intermediaries to whose DTC accounts the Book-Entry Certificates are credited,
to the extent that such actions are taken on behalf of Financial Intermediaries
whose holdings include such Book-Entry Certificates. CEDEL or the Euroclear
Operator, as the case may be, will take any other action permitted to be taken
by a Certificateholder under such Agreement on behalf of a CEDEL Participant or
Euroclear Participant only in accordance with its relevant rules and procedures
and subject to the ability of the Relevant Depository to effect such actions on
its behalf through DTC. DTC may take actions, at the direction of the related
Participants, with respect to some Certificates of a class of Book-Entry
Certificates which conflict with actions taken with respect to other
Certificates of such class.
 
     Definitive Certificates will be issued to beneficial owners of Book-Entry
Certificates, or their nominees, rather than to DTC, only if (a) DTC or the
Depositor advises the related Trustee in writing that DTC is no longer willing,
qualified or able to discharge properly its responsibilities as nominee and
depository with respect to such Book-Entry Certificates and the Depositor or
such Trustee is unable to locate a qualified successor, (b) the Depositor, at
its sole option, with the consent of such Trustee, elects to terminate a book-
entry system through DTC, or (c) after the occurrence of an Event of Default (as
defined in the related Prospectus Supplement), beneficial owners having
Percentage Interests aggregating not less than 50% of the aggregate current
principal amount of such Book-Entry Certificates advise the Trustee and DTC
through the Financial Intermediaries and the DTC Participants in writing that
the continuation of a book-entry system through DTC (or a successor thereto) is
no longer in the best interests of beneficial owners.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee for such a Series will be required to notify
all beneficial owners of the occurrence of such event and the availability
through DTC of Definitive Certificates. Upon surrender by DTC of the global
certificate or certificates representing the Book-Entry Certificates and
instructions for re-registration, the Trustee will issue Definitive
Certificates, and thereafter the Trustee will recognize the holders of such
Definitive Certificates as Certificateholders of such Series under the related
Agreement.
 
     Although DTC, CEDEL and Euroclear have agreed to the foregoing procedures
in order to facilitate transfers of Certificates among participants of DTC,
CEDEL and Euroclear, they are under no obligation to perform or continue to
perform such procedures, and such procedures may be discontinued at any time.
 
     Neither the Depositor, the Master Servicer nor the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of any class of Book-Entry
Certificates held by Cede, as nominee for DTC, or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests.
 
                               CREDIT ENHANCEMENT
 
GENERAL
 
     Credit enhancement may be provided with respect to one or more classes of a
Series of Certificates or with respect to the Mortgage Assets in the related
Trust Fund. Credit enhancement may be in the form of a limited financial
guaranty policy issued by an entity named in the related Prospectus Supplement,
the subordination of one or more classes of the Certificates of such Series, the
establishment of one or more reserve funds, the use of a cross-support feature,
use of a mortgage pool insurance policy, bankruptcy bond, special hazard
insurance policy, surety bond or letters of credit described herein and in the
related Prospectus Supplement, or any combination of the foregoing. Unless
otherwise specified in the related Prospectus Supplement, any credit enhancement
will not provide protection against all risks of loss and will not guarantee
repayment of the entire principal balance of the Certificates and interest
thereon. If losses occur which exceed the amount covered by credit enhancement
or which are not covered by the credit enhancement, Certificateholders will bear
their allocable share of deficiencies.
 
                                       32
<PAGE>   151
 
SUBORDINATION
 
     If so specified in the related Prospectus Supplement, protection afforded
to holders of one or more classes of Certificates of a Series (the "Subordinated
Certificates") by means of the subordination feature will be accomplished by the
preferential right of holders of one or more other classes of such Series (the
"Senior Certificates") to distributions in respect of scheduled principal,
Principal Prepayments, interest or any combination thereof that otherwise would
have been payable to holders of Subordinated Certificates under the
circumstances and to the extent specified in the related Prospectus Supplement.
If specified in the related Prospectus Supplement, delays in receipt of
scheduled payments on the Mortgage Loans and losses on defaulted Mortgage Loans
will be borne first by the various classes of Subordinated 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
Prospectus Supplement. The aggregate distributions in respect of delinquent
payments on the Mortgage Loans over the lives of the Certificates or at any
time, the aggregate losses in respect of defaulted Mortgage Loans which must be
borne by the Subordinated Certificates by virtue of subordination and the amount
of the distributions otherwise distributable to the Subordinated
Certificateholders that will be distributable to Senior Certificateholders on
any Distribution Date may be limited as specified in the related Prospectus
Supplement. If aggregate distributions in respect of delinquent payments on the
Mortgage Loans or aggregate losses in respect of such Mortgage Loans were to
exceed an amount specified in the related Prospectus Supplement, holders of
Senior Certificates would experience losses on the Certificates.
 
     In addition to or in lieu of the foregoing, if so specified in the related
Prospectus Supplement, all or any portion of distributions otherwise payable to
holders of Subordinated Certificates on any Distribution Date may instead be
deposited into one or more Reserve Funds established with the Trustee. If so
specified in the related Prospectus Supplement, such deposits may be made on
each Distribution Date, for specified periods or until the balance in the
Reserve Funds has reached a specified amount and, following payments from the
Reserve Fund to holders of Senior Certificates or otherwise, thereafter to the
extent necessary to restore the balance in the Reserve Fund to required levels,
in each case as specified in the related Prospectus Supplement. If so specified
in the related Prospectus Supplement, amounts on deposit in the Reserve Fund may
be released to the holders of the class of Certificates specified in such
Prospectus Supplement at the times and under the circumstances specified in such
Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, various classes of
Senior Certificates and Subordinated Certificates may themselves be subordinate
in their right to receive certain distributions to other classes of Senior and
Subordinated Certificates, respectively, through a cross support mechanism or
otherwise.
 
     As between classes of Senior Certificates and as between classes of
Subordinated 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 Prospectus Supplement.
As between classes of Subordinated Certificates, payments to holders of Senior
Certificates on account of delinquencies or losses and payments to any Reserve
Fund will be allocated as specified in the related Prospectus Supplement.
 
MORTGAGE POOL INSURANCE POLICIES
 
     If specified in the related Prospectus Supplement relating to a Mortgage
Pool, a separate mortgage pool insurance policy ("Mortgage Pool Insurance
Policy") will be obtained for the Mortgage Pool and issued by the insurer (the
"Pool Insurer") named in such Prospectus 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 Mortgage Pool in an amount
equal to a percentage specified in such Prospectus Supplement of the aggregate
principal balance of such Mortgage Loans on the Cut-off Date which are not
covered as to their entire outstanding principal balances by Primary Mortgage
Insurance Policies. As more fully described below, the Servicer will present
claims thereunder to the Pool Insurer on behalf of itself, the Trustee and the
holders of the Certificates. 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
 
                                       33
<PAGE>   152
 
satisfaction of certain conditions precedent described below. Unless otherwise
specified in the related Prospectus 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.
 
     Unless otherwise specified in the related Prospectus 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
property securing the defaulted Mortgage Loan at a price equal to the principal
balance thereof plus accrued and unpaid interest at the Mortgage Rate to the
date of purchase and certain expenses incurred by the Master 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
property securing a defaulted Mortgage Loan 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
Master 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 Master Servicer for its expenses and (ii) such expenses
will be recoverable by it through proceeds of the sale of the property or
proceeds of the related Mortgage Pool Insurance Policy or any related Primary
Mortgage Insurance Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, 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 above and, in such
event, might give rise to an obligation on the part of such Seller to purchase
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.
 
     Unless otherwise specified in the related Prospectus Supplement, 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 Master Servicer as well as accrued
interest on delinquent Mortgage Loans to the date of payment of the claim,
unless otherwise specified in the related Prospectus Supplement. Accordingly, if
aggregate net claims paid under any 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 the Certificateholders.
 
SPECIAL HAZARD INSURANCE POLICIES
 
     If specified in the related Prospectus 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 Prospectus
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
                                       34
<PAGE>   153
 
caused by certain hazards (including earthquakes and, to a limited extent, tidal
waves and related water damage or as otherwise specified in the related
Prospectus 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 "The Pooling and Servicing Agreement -- Hazard Insurance." Each Special
Hazard Insurance Policy will not cover losses occasioned by fraud or conversion
by the Trustee or Master 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 Prospectus
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 Prospectus 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 Master 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 Master
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 the property will
further 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 and in the manner specified in an applicable Prospectus
Supplement, the Master 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 relating to such Certificates in lieu
thereof 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 Prospectus Supplement, a bankruptcy bond
("Bankruptcy Bond") for proceedings under the federal Bankruptcy Code will be
issued by an insurer named in such Prospectus Supplement. Each Bankruptcy Bond
will cover, to the extent specified in the related Prospectus 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 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 Prospectus Supplement. Coverage under a
Bankruptcy Bond may be canceled or reduced 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 Lenders."

     To the extent specified in an applicable Prospectus Supplement, the Seller
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 relating to such
Certificates in lieu thereof 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 FUNDS
 
     If so specified in the related Prospectus 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 for such Series. The related Prospectus Supplement will
specify whether or not such Reserve Funds will be included in the Trust Fund for
such Series.
 
     The Reserve Fund for a Series will be funded (i) by the deposit therein of
cash, U.S. Treasury securities, instruments evidencing ownership of principal or
interest payments thereon, letters of credit, demand notes, certificates of
deposit or a combination thereof in the aggregate amount specified in the
related Prospectus Supplement, (ii) by the deposit therein from time to time of
certain amounts, as specified in the related Prospectus Supplement to which the
Subordinated Certificateholders, if any, would otherwise be entitled or (iii) in
such other manner as may be specified in the related Prospectus Supplement.
 
     Any amounts on deposit in the Reserve Fund and the proceeds of any other
instrument upon maturity will be held in cash or will be invested in Permitted
Investments which, unless otherwise specified in the related Prospectus
Supplement, will include obligations of the United States and certain agencies
thereof, certificates of deposit, certain commercial paper, time deposits and
bankers acceptances sold by eligible commercial banks and certain repurchase
agreements of United States government securities with eligible commercial
banks. If a letter of credit is deposited with the Trustee, such letter of
credit will be irrevocable. Unless otherwise specified in the related Prospectus
Supplement, any instrument deposited therein will name the Trustee, in its
capacity as trustee for the holders of the Certificates, 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 Prospectus Supplement.
 
     Any amounts so deposited and payments on instruments so deposited will be
available for withdrawal from the Reserve Account for distribution to the
holders of Certificates for the purposes, in the manner and at the times
specified in the related Prospectus Supplement.
 
CROSS SUPPORT
 
     If specified in the related Prospectus Supplement, the beneficial ownership
of separate groups of assets included in a Trust Fund may be evidenced by
separate classes of the related Series of 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 Trust Fund. The related
Prospectus Supplement for a Series which includes a cross-support feature will
describe the manner and conditions for applying such cross support feature.
 
     If specified in the related Prospectus Supplement, the coverage provided by
one or more forms of credit support may apply concurrently to two or more
related Trust Funds. If applicable, the related Prospectus Supplement will
identify the Trust Funds to which such credit support relates and the manner of
determining the amount of the coverage provided thereby and of the application
of such coverage to the identified Trust Funds.
 
LIMITED GUARANTEE
 
     If specified in the Prospectus Supplement with respect to a Series of
Certificates, credit enhancement may be provided in the form of a Limited
Guarantee issued by a guarantor named therein. If specified in the
 
                                       36
<PAGE>   155
 
related Prospectus Supplement, a Limited Guarantee may be provided by an
affiliate or affiliates of the Depositor.
 
LETTER OF CREDIT
 
     Alternative credit support with respect to a Series of Certificates may be
provided by the issuance of a Letter of Credit by the bank or financial
institution specified in the applicable Prospectus Supplement. The coverage,
amount and frequency of any reduction in coverage provided by a Letter of Credit
issued with respect to a Series of Certificates will be set forth in the related
Prospectus Supplement.
 
SURETY BONDS
 
     If specified in the Prospectus Supplement relating to a Series of
Certificates, credit support with respect to one or more Classes of Certificates
of a Series may be provided by the issuance of a Surety Bond issued by a
financial guarantee insurance company specified in the applicable Prospectus
Supplement. The coverage, amount and frequency of any reduction in coverage
provided by a Surety Bond will be set forth in the related Prospectus
Supplement.
 
OVERCOLLATERALIZATION
 
     If specified in the related Prospectus Supplement, credit support may
consist of overcollateralization whereby the aggregate principal amount of the
Mortgage Assets, including any Subsequent Mortgage Assets, exceeds the aggregate
Certificate Balance of the Certificates. Such overcollateralization may exist on
the Closing Date or develop thereafter as a result of the application of certain
interest collections, in excess of amounts necessary to pay the Pass-Through
Rate on the Certificates, received in connection with the Mortgage Assets,
including any Subsequent Mortgage Assets. The existence of any
overcollateralization and the manner, if any, by which it increases or
decreases, will be set forth in the related Prospectus Supplement.
 
                      YIELD AND PREPAYMENT CONSIDERATIONS
 
     The yields to maturity and weighted average lives of the Certificates will
be affected primarily by the amount and timing of principal payments received on
or in respect of the Mortgage Assets included in the related Trust Fund. The
original terms to maturity of the Mortgage Loans in a given Mortgage Pool will
vary depending upon the type of Mortgage Loans included therein. Each Prospectus
Supplement will contain information with respect to the type and maturities of
the Mortgage Loans in the related Mortgage Pool. Unless otherwise specified in
the related Prospectus Supplement, Mortgage Loans may be prepaid without penalty
in full or in part at any time. The prepayment experience on the Mortgage Loans
in a Mortgage Pool will affect the life of the related Series of Certificates.
 
     A number of factors, including, but not limited to, homeowner mobility,
economic conditions, the presence and enforceability of due-on-sale clauses,
mortgage market interest rates and the availability of mortgage funds, may
affect prepayment experience of Mortgage Loans.
 
     Unless otherwise provided in the related Prospectus Supplement, all
conventional Mortgage Loans will contain due-on-sale provisions permitting the
mortgagee to accelerate the maturity of the loan upon sale or certain transfers
by the mortgagor of the underlying Mortgaged Property. Mortgage Loans insured by
the FHA, and Mortgage Loans partially guaranteed by the VA, are assumable with
the consent of the FHA and the VA, respectively. Thus, the rate of prepayments
on such Mortgage Loans may be lower than that of conventional Mortgage Loans
bearing comparable interest rates. Unless otherwise provided in the related
Prospectus Supplement, the Master Servicer generally will enforce any
due-on-sale or due-on-encumbrance clause, to the extent it has knowledge of the
conveyance or further encumbrance or the proposed conveyance or proposed further
encumbrance of the Mortgaged Property and reasonably believes that it is
entitled to do so under applicable law; provided, however, the Master Servicer
will not take any enforcement action that would impair or threaten to impair any
recovery under any related insurance policy. See "The Pooling and Servicing
Agreement -- Collection Procedures" and "Certain Legal Aspects of the Mortgage
Loans" for a description
 
                                       37
<PAGE>   156
 
of certain provisions of each Agreement and certain legal developments that may
affect the prepayment experience on the Mortgage Loans.
 
     The rate of prepayments with respect to conventional mortgage loans has
fluctuated significantly in recent years. In general, if prevailing rates fall
significantly below the Mortgage Rates borne by the Mortgage Loans, such
Mortgage Loans are likely to be subject to higher prepayment rates than if
prevailing interest rates remain at or above such Mortgage Rates. Conversely, if
prevailing interest rates rise appreciably above the Mortgage Rates borne by the
Mortgage Loans, such Mortgage Loans are likely to experience a lower prepayment
rate than if prevailing rates remain at or below such Mortgage Rates. However,
there can be no assurance that such will be the case.
 
     When a full prepayment is made on a Mortgage Loan, the Mortgagor is charged
interest on the principal amount of the Mortgage Loan so prepaid only for the
number of days in the month actually elapsed up to the date of the prepayment
rather than for a full month. If so specified in the related Prospectus
Supplement, the effect of prepayments in full will be to reduce the amount of
interest passed through in the following month to holders of Certificates
because interest on the principal amount of any Mortgage Loan so prepaid will be
paid only to the date of prepayment. Partial prepayments in a given month may be
applied to the outstanding principal balances of the Mortgage Loans so prepaid
on the first day of the month of receipt or the month following receipt. In the
latter case, partial prepayments will not reduce the amount of interest passed
through in such month. Unless otherwise specified in the related Prospectus
Supplement, both full and partial prepayments will not be passed through until
the month following receipt.
 
     The effective yield to Certificateholders will be slightly lower than the
yield otherwise produced by the applicable Pass-Through Rate and purchase price
because while interest will accrue on each Mortgage Loan from the first day of
the month (unless otherwise provided in the related Prospectus Supplement), the
distribution of such interest will not be made earlier than the Distribution
Date in the month following the month of accrual.
 
     Under certain circumstances, the Master Servicer or the holder(s) of the
residual interest(s) in a REMIC may have the option to purchase the assets of a
Trust Fund thereby effecting earlier retirement of the related Series of
Certificates. See "The Pooling and Servicing Agreement -- Termination; Optional
Termination."
 
     If so specified in the related Prospectus Supplement, upon notification
from a Mortgagor of such Mortgagor's intent to convert from an adjustable
interest rate to a fixed interest rate, and prior to the conversion of such
Mortgage Loan, the Seller will be obligated to purchase such related Mortgage
Loan. Any such purchase of a Mortgage Loan would have the effect of a prepayment
in full of the Mortgage Loan.
 
     From time to time, a Seller or its affiliates may solicit the refinancing
of loans (including the Mortgage Loans) by offering a new loan to the borrower.
Any such refinancing of a Mortgage Loan would have the effect of a prepayment in
full of the Mortgage Loan.
 
     Factors other than those identified herein and in the related Prospectus
Supplement could significantly affect principal prepayments at any time and over
the lives of the Certificates. The relative contribution of the various factors
affecting prepayment may also vary from time to time. There can be no assurance
as to the rate of payment of principal of the Mortgage Assets at any time or
over the lives of the Certificates.
 
     The Prospectus Supplement relating to a Series of Certificates will discuss
in greater detail the effect of the rate and timing of principal payments
(including prepayments), delinquencies and losses on the yield, weighted average
lives and maturities of such Certificates.
 
                      THE POOLING AND SERVICING AGREEMENT
 
     Set forth below is a summary of certain provisions of each Agreement which
are not described elsewhere in this Prospectus. Where particular provisions or
terms used in the Agreements are referred to, such provisions or terms are as
specified in the Agreements.
 
                                       38

ASSIGNMENT OF MORTGAGE ASSETS
 
     Assignment of the Mortgage Loans.  Unless otherwise specified in the
related Prospectus Supplement, at the time of issuance of the Certificates of a
Series, the Depositor will cause the Mortgage Loans comprising the related Trust
Fund to be assigned to the Trustee, together with all principal and interest
received by or on behalf of the Depositor on or with respect to such Mortgage
Loans after the Cut-off Date, other than principal and interest due on or before
the Cut-off Date and other than any Retained Interest specified in the related
Prospectus Supplement. The Trustee will, concurrently with such assignment,
deliver the Certificates to the Depositor in exchange for the Mortgage Loans.
Each Mortgage Loan will be identified in a schedule appearing as an exhibit to
the related Agreement. Such schedule will include information as to the
outstanding principal balance of each Mortgage Loan after application of
payments due on the Cut-off Date, as well as information regarding the Mortgage
Rate, the current scheduled monthly payment of principal and interest, the
maturity of the loan, the Loan-to-Value Ratio (or, in the case of Home Equity
Loans, the Combined Loan-to-Value Ratio) at origination and certain other
information. If specified in the related Prospectus Supplement, the Depositor
will deliver or cause to be delivered to the Trustee loans at a predetermined
price for inclusion in the Trust Fund within three months after the issuance of
the Certificates. The related Prospectus Supplement for the Trust Fund will
specify whether, and the terms, conditions and manner under which Subsequent
Mortgage Assets will be sold to the Trust Fund within such three month period.
 
     In addition, the Depositor will deliver or cause to be delivered to the
Trustee (or to the custodian hereinafter referred to) as to each Mortgage Loan,
among other things, (i) the mortgage note (the "Mortgage Note") endorsed without
recourse in blank or to the order of the Trustee, (ii) the mortgage, deed of
trust or similar instrument (a "Mortgage") with evidence of recording indicated
thereon (except for any Mortgage not returned from the public recording office,
in which case the Depositor will unless otherwise specified in the related
Prospectus Supplement, deliver or cause to be delivered a copy of such Mortgage
together with a certificate that the original of such Mortgage was delivered to
such recording office), (iii) an assignment of the Mortgage to the Trustee,
which assignment will be in recordable form, and (iv) such other security
documents as may be specified in the related Prospectus Supplement or the
related Agreement. Unless otherwise specified in the related Prospectus
Supplement, the Depositor will promptly cause the assignments of the related
loans to be recorded in the appropriate public office for real property records,
except in states in which, in the opinion of counsel acceptable to the Trustee,
such recording is not required to protect the Trustee's interest in such loans
against the claim of any subsequent transferee or any successor to or creditor
of the Depositor or the originator of such loans.
 
     With respect to any Mortgage Loans which are Cooperative Loans, the
Depositor will cause to be delivered to the Trustee, the related original
cooperative note endorsed without recourse in blank or to the order of the
Trustee, the original security agreement, the proprietary lease or occupancy
agreement, the recognition agreement, an executed financing agreement and the
relevant stock certificate, related blank stock powers and any other document
specified in the related Prospectus Supplement. The Depositor will cause to be
filed in the appropriate office an assignment and a financing statement
evidencing the Trustee's security interest in each Cooperative Loan.
 
     The Trustee (or the custodian hereinafter referred to) will review such
Mortgage Loan documents within the time period specified in the related
Prospectus Supplement after receipt thereof, and the Trustee will hold such
documents in trust for the benefit of the Certificateholders. Unless otherwise
specified in the related Prospectus Supplement, if any such document is found to
be missing or defective in any material respect, the Trustee (or such custodian)
will notify the Master Servicer and the Depositor, and the Master Servicer will
notify the related Seller. If the Seller cannot cure the omission or defect
within the time period specified in the related Prospectus Supplement after
receipt of such notice, the Seller will be obligated to purchase the related
Mortgage Loan from the Trustee at the Purchase Price or, if so specified in the
related Prospectus Supplement, replace such Mortgage Loan with another mortgage
loan that meets certain requirements set forth therein. There can be no
assurance that a Seller will fulfill this purchase obligation. Although the
Master Servicer may be obligated to enforce such obligation to the extent
described above under "Mortgage Loan Program -- Representations by Sellers;
Repurchases," neither the Master Servicer nor the Depositor will be obligated to
purchase such Mortgage Loan if the Seller defaults on its purchase obligation,
unless such breach
                                       39
<PAGE>   158
 
also constitutes a breach of the representations or warranties of the Seller or
the Depositor, as the case may be. Unless otherwise specified in the related
Prospectus Supplement, this purchase obligation constitutes the sole remedy
available to the Certificateholders or the Trustee for omission of, or a
material defect in, a constituent document.
 
     A custodian may maintain possession of, and, if applicable, review the
documents relating to, the Mortgage Loans as agent of the Trustee pursuant
either to the terms of an Agreement or a separate custodial agreement.
 
     Notwithstanding the foregoing provisions, with respect to a Trust Fund for
which a REMIC election is to be made, unless the related Prospectus Supplement
otherwise provides, no purchase of a Mortgage Loan will be made if such purchase
would result in a prohibited transaction tax under the Code.
 
     Assignment of Agency Securities.  The Depositor will cause the Agency
Securities to be registered in the name of the Trustee or its nominee, and the
Trustee concurrently will execute, countersign and deliver the Certificates.
Each Agency Security will be identified in a schedule appearing as an exhibit to
the Agreement, which will specify as to each Agency Security 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.
 
     Assignment of Private Mortgage-Backed Securities.  The Depositor will cause
Private Mortgage-Backed Securities to be registered in the name of the Trustee.
The Trustee (or the custodian) will have possession of any certificated Private
Mortgage-Backed Securities. Unless otherwise specified in the related Prospectus
Supplement, the Trustee will not be in possession of or be assignee of record of
any underlying assets for a Private Mortgage-Backed Security. See "The Trust
Fund -- Private Mortgage-Backed Securities" herein. Each Private Mortgage-Backed
Security will be identified in a schedule appearing as an exhibit to the related
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
Mortgage-Backed Security conveyed to the Trustee.
 
PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO COLLECTION ACCOUNT
 
     The Master Servicer will establish and maintain or cause to be established
and maintained with respect to the related Trust Fund a separate account or
accounts for the collection of payments on the related Mortgage Assets in the
Trust Fund (the "Collection Account"), which unless otherwise specified in the
related Prospectus Supplement, must be either (i) maintained with a depository
institution the short-term debt obligations of which (or in the case of a
depository institution that is the principal subsidiary of a holding company,
the short-term debt obligations of which) are rated in the highest short-term
rating category by the nationally recognized statistical rating organization(s)
that rated one or more classes of the related Series of Certificates (each, a
"Rating Agency"), (ii) an account or accounts the deposits in which are fully
insured by either the BIF or SAIF, (iii) an account or accounts the deposits in
which are insured by the BIF or SAIF (to the limits established by the FDIC),
and the uninsured deposits in which are otherwise secured such that, as
evidenced by an opinion of counsel, the Certificateholders have a claim with
respect to the funds in the Collection Account or a perfected first priority
security interest against any collateral securing such funds that is superior to
the claims of any other depositors or general creditors of the depository
institution with which the Collection Account is maintained, (iv) a trust
account or accounts maintained with the trust department of a federal or a state
chartered depository institution or trust company, acting in a fiduciary
capacity or (v) an account or accounts otherwise acceptable to each Rating
Agency. The Collection Account may be maintained at FUNB so long as it maintains
a long-term unsecured rating of at least A by Standard & Poor's Ratings Services
and A2 by Moody's Investor's Service, Inc., and a short-term rating of at least
A-1 by Standard & Poor's Ratings Services and P-1 by Moody's Investor's Service,
Inc. Investments in which amounts in the Collection Account may be invested are
limited to United States government securities and other high-quality
investments ("Eligible Investments"). A Collection 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. Unless otherwise
specified in the related Prospectus Supplement, the Master Servicer or its
designee will be entitled to receive any such interest or other income earned on
funds in the Collection
 
                                       40
<PAGE>   159
 
Account as additional compensation and will be obligated to deposit in the
Collection Account the amount of any loss immediately as realized. The
Collection Account may be maintained with the Master Servicer or with a
depository institution that is an affiliate of the Master Servicer, provided it
meets the standards set forth above.
 
     The Master Servicer will deposit or cause to be deposited in the Collection
Account for each Trust Fund on a daily basis, to the extent applicable and
unless otherwise specified in the related Prospectus Supplement and provided in
the Agreement, the following payments and collections received or advances made
by or on behalf of it subsequent to the Cut-off Date (other than payments due on
or before the Cut-off Date and exclusive of any amounts representing Retained
Interest):
 
          (i) all payments on account of principal, including Principal
     Prepayments and, if specified in the related Prospectus Supplement,
     prepayment penalties, on the Mortgage Loans;
 
          (ii) all payments on account of interest on the Mortgage Loans, net of
     applicable servicing compensation;
 
          (iii) (a) all proceeds (net of unreimbursed payments of property
     taxes, insurance premiums and similar items ("Insured Expenses") incurred,
     and unreimbursed advances made, if any, by the Servicer or any
     Sub-Servicer) of the hazard insurance policies and any Primary Mortgage
     Insurance Policies, to the extent such proceeds are not applied to the
     restoration of the property or released to the Mortgagor in accordance with
     the Master Servicer's normal servicing procedures (collectively, "Insurance
     Proceeds") and (b) "Net Liquidation Proceeds" consisting of all other cash
     amounts received and retained in connection with the liquidation of
     defaulted Mortgage Loans, by foreclosure or otherwise ("Liquidation
     Proceeds") net of unreimbursed expenses incurred in connection with
     liquidation or foreclosure ("Liquidation Expenses") and unreimbursed
     advances made, if any, by the Master Servicer or any Sub-Servicer, and (c)
     any net proceeds received on a monthly basis with respect to any properties
     acquired on behalf of the Certificateholders by foreclosure or deed in lieu
     of foreclosure;
 
          (iv) all proceeds of any Mortgage Loan or property in respect thereof
     purchased by any Seller as described under "Mortgage Loan
     Program -- Representations by Sellers; Repurchases" or "-- Assignment of
     Mortgage Assets" above and all proceeds of any Mortgage Loan repurchased as
     described under "-- Termination; Optional Termination" below;
 
          (v) all payments required to be deposited in the Collection Account
     with respect to any deductible clause in any blanket insurance policy
     described under "-- Hazard Insurance" below;
 
          (vi) any amount required to be deposited by the Master Servicer in
     connection with losses realized on investments for the benefit of the
     Master Servicer of funds held in the Collection Account and, to the extent
     specified in the related Prospectus Supplement, any payments required to be
     made by the Master Servicer in connection with prepayment interest
     shortfalls; and
 
          (vii) all other amounts required to be deposited in the Collection
     Account pursuant to the Agreement.
 
     The Master Servicer (or the Depositor, as applicable) may from time to time
direct the institution which maintains the Collection Account, unless otherwise
specified in the related Prospectus Supplement, to withdraw funds from the
Collection Account for the following purposes:
 
          (i) to pay to the Master Servicer the servicing fees described in the
     related Prospectus Supplement, the Master Servicing Fee and, as additional
     servicing compensation, earnings on or investment income with respect to
     funds in the amounts in the Collection Account credited thereto;
 
          (ii) to reimburse the Master Servicer for Advances;
 
          (iii) to reimburse the Master Servicer for any Advances previously
     made which the Master Servicer has determined to be nonrecoverable;
 
                                       41
<PAGE>   160
 
          (iv) to reimburse the Master Servicer from Insurance Proceeds for
     expenses incurred by the Master Servicer and covered by the related
     insurance policies;
 
          (v) to reimburse the Master Servicer for unpaid Master Servicing Fees
     and unreimbursed out-of-pocket costs and expenses incurred by the Master
     Servicer in the performance of its servicing obligations, such right of
     reimbursement being limited to amounts received representing late
     recoveries of the payments for which such advances were made;
 
          (vi) to pay to the Master Servicer, with respect to each Mortgage Loan
     or property acquired in respect thereof that has been purchased by the
     Master Servicer pursuant to the Agreement, all amounts received thereon and
     not taken into account in determining the related Principal Balance of such
     repurchased Mortgage Loan;
 
          (vii) to reimburse the Master Servicer or the Depositor for expenses
     incurred and reimbursable pursuant to the Agreement;
 
          (viii) to withdraw any amount deposited in the Collection Account and
     not required to be deposited therein; and
 
          (ix) to clear and terminate the Collection Account upon termination of
     the Agreement.
 
     In addition, unless otherwise specified in the related Prospectus
Supplement, on or prior to the Business Day immediately preceding each
Distribution Date, the Master Servicer shall withdraw from the Collection
Account the amount of Available Distribution Amount, to the extent on deposit,
for deposit in an account maintained by the Trustee for the related Series of
Certificates.
 
PRE-FUNDING ACCOUNT
 
     If so specified in the Prospectus Supplement, the related Agreement may
provide for the transfer by the Depositor of additional Mortgage Assets (the
"Subsequent Mortgage Assets") to the related Trust Fund after the Closing Date
for the related Certificates. Such Subsequent Mortgage Assets will be required
to conform to the requirements set forth in the related Agreement providing for
such transfer. As specified in the related Prospectus Supplement, such transfer
may be funded by the establishment of a Pre-Funding Account (a "Pre-Funding
Account"). If a Pre-Funding Account is established, all or a portion of the
proceeds of the sale of one or more classes of Certificates of the related
Series will be deposited in such account (the "Pre-Funded Amount") to be
released as additional Mortgage Assets are transferred to the Trust Fund. The
related Agreement will establish a period of time (which will be no longer than
three months following the related Closing Date) within which such transfers
must be made (the "Funding Period"). Unless otherwise specified in the related
Prospectus Supplement, amounts set aside to fund such transfers (whether in a
Pre-Funding Account or otherwise) and not so applied within the Funding Period
will be deemed to be principal prepayments and applied in the manner set forth
in the Prospectus Supplement.
 
COLLECTION PROCEDURES
 
     The Servicer, directly or through one or more Sub-Servicers, will make
reasonable efforts to collect all payments called for under the Mortgage Loans
and will, consistent with each Agreement and any Mortgage Pool Insurance Policy,
Primary Mortgage Insurance Policy, FHA Insurance, VA Guaranty Policy and
Bankruptcy Bond or alternative arrangements, follow such collection procedures
as are customary with respect to mortgage loans that are comparable to the
Mortgage Loans. Consistent with the above, the Master Servicer may, in its
discretion, (i) waive any assumption fee, late payment or other charge in
connection with a Mortgage Loan and (ii) to the extent not inconsistent with the
coverage of such Mortgage Loan by a Mortgage Pool Insurance Policy, Primary
Mortgage Insurance Policy, FHA Insurance, VA Guaranty or Bankruptcy Bond or
alternative arrangements, if applicable, arrange with a Mortgagor a schedule for
the liquidation of delinquencies in a manner that is determined by the Master
Servicer to be customary with respect to comparable mortgage loans. Such
schedules for liquidation of delinquencies for Mortgage Loans other than Home
Equity Loans generally do not exceed 180 days. To the extent the Master Servicer
is
 
                                       42
<PAGE>   161
 
obligated to make or to cause to be made Advances, such obligation will remain
during the period of any such arrangement.
 
     Unless otherwise specified in the related Prospectus Supplement, in any
case in which property securing a Mortgage Loan has been, or is about to be,
conveyed by the mortgagor or obligor, the Master Servicer will, to the extent it
has knowledge of such conveyance or proposed conveyance, exercise or cause to be
exercised its rights to accelerate the maturity of such Mortgage Loan under any
due-on-sale clause applicable thereto, but only if the exercise of such rights
is permitted by applicable law; provided, however, the Master Servicer will not
take any enforcement action that would impair or threaten to impair any recovery
under any related insurance policy. If these conditions are not met or if the
Master Servicer reasonably believes it is unable under applicable law to enforce
such due-on-sale clause, or if such Mortgage Loan is insured by the FHA or
partially guaranteed by the VA, the Master Servicer will enter into or cause to
be entered into an assumption agreement or a substitution agreement with the
person to whom such property has been or is about to be conveyed, pursuant to
which such person becomes liable for repayment of the Mortgage Loan.
 
     Any fee collected by or on behalf of the Master Servicer for entering into
an assumption agreement will be retained by or on behalf of the Master Servicer
as additional servicing compensation. See "Certain Legal Aspects of the Mortgage
Loans -- Due-on-Sale Clauses." In connection with any such assumption, the terms
of the related Mortgage Loan may not be changed.
 
HAZARD INSURANCE
 
     The Master Servicer will require the mortgagor or obligor on each Mortgage
Loan to maintain a hazard insurance policy providing for no less than the
coverage of the standard form of fire insurance policy with extended coverage
customary for the type of Mortgaged Property in the state in which such
Mortgaged Property is located. Such coverage will be in an amount not less than
the replacement value of the improvements securing such Mortgage Loan or the
principal balance owing on such Mortgage Loan, whichever is less. All amounts
collected by the Master 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 or obligor in accordance with the Master Servicer's normal
servicing procedures) will be deposited in the related Collection Account. In
the event that the Master Servicer maintains a blanket policy insuring against
hazard losses on all the Mortgage Loans comprising part of a Trust Fund, it will
conclusively be deemed to have satisfied its obligation relating to the
maintenance of hazard insurance. Such blanket policy may contain a deductible
clause, in which case the Master Servicer will be required to deposit from its
own funds into the related Collection Account the amounts which would have been
deposited therein but for such clause.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements securing a Mortgage Loan
by fire, lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. Although the policies relating to the Mortgage Loans may have been
underwritten by different insurers under different state laws in accordance with
different applicable forms and therefore may not contain identical terms and
conditions, the basic terms thereof are dictated by respective state laws, and
most such policies typically do not cover any physical damage resulting from the
following: war, revolution, governmental actions, floods and other water-related
causes, earth movement (including earthquakes, landslides and mud flows),
nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic animals,
theft and, in certain cases, vandalism. The foregoing list is merely indicative
of certain kinds of uninsured risks and is not intended to be all inclusive. If
the Mortgaged Property securing a Mortgage Loan is located in a federally
designated special flood area, the Master Servicer will require the mortgagor or
obligor to obtain and maintain flood insurance, to the extent such insurance is
available.
 
     The hazard insurance policies covering properties securing the Mortgage
Loans 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 insured property in order to recover the full
amount of any partial loss. If the insured's coverage falls below this specified
percentage, then the insurer's liability in the event of partial loss will not
exceed the larger of (i) the actual cash value (generally defined as replacement
cost at the
 
                                       43
<PAGE>   162
 
time and place of loss, less physical depreciation) of the improvements damaged
or destroyed or (ii) such proportion of the loss as the amount of insurance
carried bears to the specified percentage of the full replacement cost of such
improvements. Since the amount of hazard insurance the Master Servicer may cause
to be maintained on the improvements securing the Mortgage Loans declines as the
principal balances owing thereon decrease, and since improved real estate
generally has appreciated in value over time in the past, the effect of this
requirement in the event of partial loss may be that hazard insurance proceeds
will be insufficient to restore fully the damaged property. If specified in the
related Prospectus Supplement, a special hazard insurance policy will be
obtained to insure against certain of the uninsured risks described above. See
"Credit Enhancement -- Special Hazard Insurance Policies."
 
     The Master Servicer will not require that a standard hazard or flood
insurance policy be maintained on the cooperative dwelling relating to any
Cooperative Loan. Generally, the Cooperative itself is responsible for
maintenance of hazard insurance for the property owned by the Cooperative and
the tenant-stockholders of that Cooperative do not maintain individual hazard
insurance policies. To the extent, however, that a Cooperative and the related
borrower on a Cooperative Loan do not maintain such insurance or do not maintain
adequate coverage or any insurance proceeds are not applied to the restoration
of damaged property, any damage to such borrower's cooperative dwelling or such
Cooperative's building could significantly reduce the value of the collateral
securing such Cooperative Loan to the extent not covered by other credit
support.
 
REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
     Primary Mortgage Insurance Policies.  The Master Servicer will maintain or
cause to be maintained, as the case may be, in full force and effect, to the
extent specified in the related Prospectus Supplement, a Primary Mortgage
Insurance Policy with regard to each Mortgage Loan for which such coverage is
required. Primary Mortgage Insurance Policies are not required for Home Equity
Loans. The Master Servicer will not cancel or refuse to renew any such Primary
Mortgage Insurance Policy in effect at the time of the initial issuance of a
Series of Certificates that is required to be kept in force under the applicable
Agreement unless the replacement Primary Mortgage Insurance Policy for such
canceled or nonrenewed policy is maintained with an insurer whose claims-paying
ability is sufficient to maintain the current rating of the classes of
Certificates of such Series that have been rated.
 
     Although the terms and conditions of primary mortgage insurance vary, the
amount of a claim for benefits under a Primary Mortgage Insurance Policy
covering a Mortgage Loan will consist of the insured percentage of the unpaid
principal amount of the covered Mortgage Loan and accrued and unpaid interest
thereon and reimbursement of certain expenses, less (i) all rents or other
payments collected or received by the insured (other than the proceeds of hazard
insurance) that are derived from or in any way related to the Mortgaged
Property, (ii) hazard insurance proceeds in excess of the amount required to
restore the Mortgaged Property and which have not been applied to the payment of
the Mortgage Loan, (iii) amounts expended but not approved by the issuer of the
related Primary Mortgage Insurance Policy (the "Primary Insurer"), (iv) claim
payments previously made by the Primary Insurer and (v) unpaid premiums.
 
     Primary Mortgage Insurance Policies reimburse certain losses sustained by
reason of defaults in payments by borrowers. Primary Mortgage Insurance Policies
will not insure against, and exclude from coverage, a loss sustained by reason
of a default arising from or involving certain matters, including (i) fraud or
negligence in origination or servicing of the Mortgage Loans, including
misrepresentation by the originator, borrower or other persons involved in the
origination of the Mortgage Loan; (ii) failure to construct the Mortgaged
Property subject to the Mortgage Loan in accordance with specified plans; (iii)
physical damage to the Mortgaged Property; and (iv) the related Servicer not
being approved as a servicer by the Primary Insurer.
 
     Recoveries Under a Primary Mortgage Insurance Policy.  As conditions
precedent to the filing of or payment of a claim under a Primary Mortgage
Insurance Policy covering a Mortgage Loan, the insured will be required to (i)
advance or discharge (a) all hazard insurance policy premiums and (b) as
necessary and approved in advance by the Primary Insurer, (1) real estate
property taxes, (2) all expenses required to maintain the related Mortgaged
Property in at least as good a condition as existed at the effective date of
such Primary Mortgage Insurance Policy, ordinary wear and tear excepted, (3)
Mortgaged Property sales expenses,
 
                                       44
<PAGE>   163
 
(4) any outstanding liens (as defined in such Primary Mortgage Insurance Policy)
on the Mortgaged Property and (5) foreclosure costs, including court costs and
reasonable attorneys' fees; (ii) in the event of any physical loss or damage to
the Mortgaged Property, have the Mortgaged Property restored and repaired to at
least as good a condition as existed at the effective date of such Primary
Mortgage Insurance Policy, ordinary wear and tear excepted; and (iii) tender to
the Primary Insurer good and merchantable title to and possession of the
Mortgaged Property.
 
     The Master Servicer, on behalf of itself, the Trustee and the
Certificateholders, will present claims to the insurer under each Primary
Mortgage Insurance Policy, and will take such reasonable steps as are necessary
to receive payment or to permit recovery thereunder with respect to defaulted
Mortgage Loans. As set forth above, all collections by or on behalf of the
Master Servicer under any Primary Mortgage Insurance Policy and, when the
Mortgaged Property has not been restored, the hazard insurance policy, are to be
deposited in the Collection Account, subject to withdrawal as heretofore
described.
 
     If the Mortgaged Property securing a defaulted Mortgage Loan is damaged and
proceeds, if any, from the related hazard insurance policy are insufficient to
restore the damaged Mortgaged Property to a condition sufficient to permit
recovery under the related Primary Mortgage Insurance Policy, if any, the Master
Servicer is not required to expend its own funds to restore the damaged
Mortgaged Property unless it determines (i) that such restoration will increase
the proceeds to Certificateholders on liquidation of the Mortgage Loan after
reimbursement of the Master Servicer for its expenses and (ii) that such
expenses will be recoverable by it from related Insurance Proceeds or
Liquidation Proceeds.
 
     If recovery on a defaulted Mortgage Loan under any related Primary Mortgage
Insurance Policy is not available for the reasons set forth in the preceding
paragraph, or if the defaulted Mortgage Loan is not covered by a Primary
Mortgage Insurance Policy, the Master Servicer will be obligated to follow or
cause to be followed such normal practices and procedures as it deems necessary
or advisable to realize upon the defaulted Mortgage Loan. If the proceeds of any
liquidation of the Mortgaged Property securing the defaulted Mortgage Loan are
less than the principal balance of such Mortgage Loan plus interest accrued
thereon that is payable to Certificateholders, the Trust Fund will realize a
loss in the amount of such difference plus the aggregate of any unpaid servicing
compensation and expenses incurred by the Master Servicer in connection with
such proceedings and which are reimbursable under the Agreement. In the unlikely
event that any such proceedings result in a total recovery which is, after
reimbursement to the Master Servicer of its expenses and any unpaid servicing
compensation, in excess of the principal balance of such Mortgage Loan plus
interest accrued thereon that is payable to Certificateholders, the Master
Servicer will be entitled to withdraw or retain from the Collection Account,
unless otherwise specified in the related Prospectus Supplement, amounts
representing the balance of such excess, exclusive of any amount required by law
to be forwarded to the related Mortgagor, as additional servicing compensation.
 
     If the Master Servicer or its designee recovers Insurance Proceeds which,
when added to any related Liquidation Proceeds and after deduction of certain
expenses reimbursable to the Master Servicer, exceed the principal balance of
such Mortgage Loan plus interest accrued thereon that is payable to
Certificateholders, the Master Servicer will be entitled to withdraw or retain
from the Collection Account amounts representing its normal servicing
compensation with respect to such Mortgage Loan. In the event that the Master
Servicer has expended its own funds to restore the damaged Mortgaged Property
and such funds have not been reimbursed under the related hazard insurance
policy, it will be entitled to withdraw from the Collection Account out of
related Liquidation Proceeds or Insurance Proceeds an amount equal to such
expenses incurred by it, in which event the Trust Fund may realize a loss up to
the amount so charged. Since Insurance Proceeds cannot exceed deficiency claims
and certain expenses incurred by the Master Servicer, no such payment or
recovery will result in a recovery to the Trust Fund which exceeds the principal
balance of the defaulted Mortgage Loan together with accrued interest thereon.
See "Credit Enhancement."
 
     Junior Mortgages.  The Mortgage Loans underlying the Certificates of a
Series will be secured by mortgages or deeds of trust which may be second or
more junior mortgages to other mortgages held by other lenders or institutional
investors. The rights of the Trust Fund (and therefore the holders of the
related Certificates), as mortgagee under a junior mortgage, are subordinate to
those of the mortgagee under the
 
                                       45
<PAGE>   164
 
senior mortgage, including the prior rights of the senior mortgagee to receive
hazard insurance and condemnation proceeds and to cause the property securing
the mortgage loan to be sold upon default of the mortgagor. If the property is
sold, the junior mortgagee's lien will be extinguished unless the junior
mortgagee asserts its subordinate interest in the property in foreclosure
litigation and, possibly, satisfies the defaulted senior mortgage. A junior
mortgagee may satisfy a defaulted senior loan in full and, in some states, may
cure such default and bring the senior loan current, in either event adding the
amounts expended to the balance due on the junior loan. In most states, absent a
provision in the mortgage or deed of trust, no notice of default is required to
be given to a junior mortgagee.
 
     The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard insurance policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under underlying senior mortgages will have the prior right to
collect any insurance proceeds payable under a hazard insurance policy and any
award of damages in connection with the condemnation and to apply the same to
the indebtedness secured by the senior mortgages. Proceeds in excess of the
amount of senior mortgage indebtedness, in most cases, may be applied to the
indebtedness of a junior mortgage.
 
     FHA Insurance; VA Guarantees.  Mortgage Loans designated in the related
Prospectus Supplement as insured by the FHA will be insured by the FHA as
authorized under the United States Housing Act of 1937, as amended. Such
Mortgage Loans will be insured under various FHA programs including the standard
FHA 203(b) program to finance the acquisition of one- to four-family housing
units and the FHA 245 graduated payment mortgage program. These programs
generally limit the principal amount and interest rates of the mortgage loans
insured. Mortgage Loans insured by the FHA generally require a minimum down
payment of approximately 5% of the original principal amount of the loan. No
FHA-insured Mortgage Loans relating to a Series may have an interest rate or
original principal amount exceeding the applicable FHA limits at the time of
origination of such loan.
 
     The insurance premiums for Mortgage Loans insured by the FHA are collected
by lenders approved by the Department of Housing and Urban Development ("HUD")
or by the Master Servicer or any Sub-Servicers and are paid to the FHA. The
regulations governing FHA single-family mortgage insurance programs provide that
insurance benefits are payable either upon foreclosure (or other acquisition of
possession) and conveyance of the mortgaged premises to HUD or upon assignment
of the defaulted Mortgage Loan to HUD. With respect to a defaulted FHA-insured
Mortgage Loan, the Master Servicer or any Sub-Servicer is limited in its ability
to initiate foreclosure proceedings. When it is determined, either by the Master
Servicer or any Sub-Servicer or HUD, that default was caused by circumstances
beyond the mortgagor's control, the Master Servicer or any Sub-Servicer is
expected to make an effort to avoid foreclosure by entering, if feasible, into
one of a number of available forms of forbearance plans with the mortgagor. Such
plans may involve the reduction or suspension of regular mortgage payments for a
specified period, with such payments to be made up on or before the maturity
date of the mortgage, or the recasting of payments due under the mortgage up to
or beyond the maturity date. In addition, when a default caused by such
circumstances is accompanied by certain other criteria, HUD may provide relief
by making payments to the Master Servicer or any Sub-Servicer in partial or full
satisfaction of amounts due under the Mortgage Loan (which payments are to be
repaid by the mortgagor to HUD) or by accepting assignment of the loan from the
Master Servicer or any Sub-Servicer. With certain exceptions, at least three
full monthly installments must be due and unpaid under the Mortgage Loan, and
HUD must have rejected any request for relief from the mortgagor before the
Master Servicer or any Sub-Servicer may initiate foreclosure proceedings.
 
     HUD has the option, in most cases, to pay insurance claims in cash or in
debentures issued by HUD. Currently, claims are being paid in cash, and claims
have not been paid in debentures since 1965. HUD debentures issued in
satisfaction of FHA insurance claims bear interest at the applicable HUD
debentures interest rate.
                                       46
<PAGE>   165
 
     The amount of insurance benefits generally paid by the FHA is equal to the
entire unpaid principal amount of the defaulted Mortgage Loan adjusted to
reimburse the Master Servicer or Sub-Servicer for certain costs and expenses and
to deduct certain amounts received or retained by the Master Servicer or
Sub-Servicer after default. When entitlement to insurance benefits results from
foreclosure (or other acquisition of possession) and conveyance to HUD, the
Master Servicer or Sub-Servicer is compensated for no more than two-thirds of
its foreclosure costs, and is compensated for interest accrued and unpaid prior
to such date but in general only to the extent it was allowed pursuant to a
forbearance plan approved by HUD. When entitlement to insurance benefits results
from assignment of the Mortgage Loan to HUD, the insurance payment includes full
compensation for interest accrued and unpaid to the assignment date. The
insurance payment itself, upon foreclosure of an FHA-insured Mortgage Loan,
bears interest from a date 30 days after the mortgagor's first uncorrected
failure to perform any obligation to make any payment due under the Mortgage
and, upon assignment, from the date of assignment to the date of payment of the
claim, in each case at the same interest rate as the applicable HUD debenture
interest rate as described above.
 
     Mortgage Loans designated in the related Prospectus Supplement as
guaranteed by the VA will be partially guaranteed by the VA under the
Serviceman's Readjustment Act of 1944, as amended (a "VA Guaranty Policy"). The
Serviceman's Readjustment Act of 1944, as amended, permits a veteran (or in
certain instances the spouse of a veteran) to obtain a mortgage loan guarantee
by the VA covering mortgage financing of the purchase of a one-to four-family
dwelling unit at interest rates permitted by the VA. The program has no mortgage
loan limits, requires no down payment from the purchaser and permits the
guarantee of mortgage loans of up to 30 years' duration.
 
     The maximum guarantee that may be issued by the VA under a VA guaranteed
mortgage loan depends upon the original principal amount of the mortgage loan,
as further described in 38 United States Code Section 3703(a), as amended. As of
January 1, 1996, the maximum guarantee that may be issued by the VA under a VA
guaranteed mortgage loan of more than $144,000 is the lesser of 25% of the
original principal amount of the mortgage loan and $50,750. The liability on the
guarantee is reduced or increased pro rata with any reduction or increase in the
amount of indebtedness, but in no event will the amount payable on the guarantee
exceed the amount of the original guarantee. The VA may, at its option and
without regard to the guarantee, make full payment to a mortgage holder of
unsatisfied indebtedness on a mortgage upon its assignment to the VA.
 
     With respect to a defaulted VA guaranteed Mortgage Loan, the Master
Servicer or Sub-Servicer is, absent exceptional circumstances, authorized to
announce its intention to foreclose only when the default has continued for
three months. Generally, a claim for the guarantee is submitted after
liquidation of the Mortgaged Property.
 
     The amount payable under the guarantee will be the percentage of the
VA-insured Mortgage Loan originally guaranteed applied to indebtedness
outstanding as of the applicable date of computation specified in the VA
regulations. Payments under the guarantee will be equal to the unpaid principal
amount of the loan, interest accrued on the unpaid balance of the loan to the
appropriate date of computation and limited expenses of the mortgagee, but in
each case only to the extent that such amounts have not been recovered through
liquidation of the Mortgaged Property. The amount payable under the guarantee
may in no event exceed the amount of the original guarantee.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The principal servicing compensation to be paid to the Master Servicer in
respect of its master servicing activities for each series of Certificates will
be equal to the percentage per annum described in the related Prospectus
Supplement (which may vary under certain circumstances) of the outstanding
principal balance of each Mortgage Loan, and such compensation will be retained
by it from collections of interest on such Mortgage Loan in the related Trust
Fund (the "Master Servicing Fee"). Unless otherwise specified in the related
Prospectus Supplement, as compensation for its servicing duties, the Master
Servicer will be entitled to a monthly servicing fee as described in the related
Prospectus Supplement. In addition, the Master Servicer or a Sub-Servicer will
retain all prepayment charges, assumption fees and late payment charges, to the
extent
 
                                       47
<PAGE>   166
 
collected from Mortgagors, and any benefit which may accrue as a result of the
investment of funds in the applicable Collection Account (unless otherwise
specified in the related Prospectus Supplement). The Master Servicer will be
responsible for the payment of any fees owing to any Sub-Servicer.
 
     The Master Servicer will pay or cause to be paid certain ongoing expenses
associated with each Trust Fund and incurred by it in connection with its
responsibilities under the related Agreement, including, without limitation,
payment of any fee or other amount payable in respect of any credit enhancement
arrangements, payment of the fees and disbursements of the Trustee, any
custodian appointed by the Trustee, the Certificate Registrar and any Paying
Agent, and payment of expenses incurred in enforcing the obligations of Sub-
Servicers and Sellers. The Master Servicer will be entitled to reimbursement of
certain of these expenses. In addition, as indicated in the preceding section,
the Master Servicer will be entitled to reimbursements for certain expenses
incurred by it in connection with Liquidated Mortgage Loans and in connection
with the restoration of Mortgaged Properties, such right of reimbursement being
prior to the rights of Certificateholders to receive any related Liquidation
Proceeds (including Insurance Proceeds).
 
EVIDENCE AS TO COMPLIANCE
 
     Each Agreement will provide that on or before a specified date in each
year, the Master Servicer will cause a firm of independent public accountants to
furnish a statement to the Trustee to the effect that, on the basis of the
examination by such firm conducted substantially in compliance with the audit
program applicable to the Master Servicer, the servicing by or on behalf of the
Master Servicer of mortgage loans, private mortgage-backed securities or agency
securities, under pooling and servicing agreements substantially similar to each
other (including the related Agreement) was conducted in compliance with such
agreements except for any significant exceptions or errors in records that, in
the opinion of the firm, such audit program requires it to report.
 
     Each Agreement will also provide for delivery to the Trustee, on or before
a specified date in each year, of an annual statement signed by an officer or
officers of the Master Servicer to the effect that the Master Servicer has
fulfilled its obligations under the Agreement in all material respects
throughout the preceding year or specifying any known failure to do so.
 
     Copies of the annual accountants' statement and the statement of officers
of the Master Servicer may be obtained by Certificateholders of the related
Series without charge upon written request to the Master Servicer or the Trustee
at the address set forth in the related Prospectus Supplement.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The Master Servicer under each Agreement will be named in the related
Prospectus Supplement. An entity serving as Master Servicer or Sub-Servicer may
have normal business relationships with the Depositor or the Depositor's
affiliates.
 
     Each Agreement will provide that, subject to the Master Servicer's right to
assign its rights and delegate its duties as described below, the Master
Servicer may not resign from its obligations and duties under the Agreement
unless its duties thereunder are no longer permissible under applicable law or
are in material conflict by reason of applicable law with any other activities
of a type and nature presently carried on by it, except in connection with a
permitted transfer of servicing. No such resignation will become effective until
the Trustee or a successor servicer has assumed the Master Servicer's
obligations and duties under the Agreement.
 
     Each Agreement will further provide that neither the Master Servicer, the
Depositor nor any director, officer, employee, or agent of the Master Servicer
or the Depositor will be under any liability to the related Trust Fund or
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to the Agreement, or for errors in judgment;
provided, however, neither the Master Servicer, the Depositor nor any such
person will be protected against any liability which would otherwise be imposed
by reason of any such breach of the terms and conditions of the Agreement. Each
Agreement will further provide that the Master Servicer, the Depositor and any
director, officer, employee or agent of the Master Servicer or
 
                                       48
<PAGE>   167
 
the Depositor will be entitled to indemnification by the related Trust Fund and
will be held harmless against any loss, liability or expense incurred in
connection with any legal action relating to the Agreement or the Certificates,
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 Agreement) and any loss, liability or expense
incurred by reason of any breach of the terms and conditions of the Agreement.
In addition, each Agreement will provide that neither the Master Servicer nor
the Depositor will be under any obligation to appear in, prosecute or defend any
legal action which is not incidental to its respective responsibilities under
the Agreement and which in its opinion may involve it in any expense or
liability. The Master Servicer or the Depositor may, however, in its discretion
undertake any such action which it may deem necessary or desirable with respect
to the Agreement and the rights and duties of the parties thereto and the
interests of the 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 Trust Fund and the Master Servicer or the
Depositor, as the case may be, will be entitled to be reimbursed therefor out of
funds otherwise distributable to Certificateholders.
 
     Any person into which the Master Servicer may be merged or consolidated, or
any person resulting from any merger or consolidation to which the Master
Servicer is a party, or any person succeeding to the business of the Master
Servicer, will be the successor of the Master Servicer under each Agreement. In
addition, the Master Servicer may assign its rights, and delegate its duties,
pursuant to the terms of the Agreement.
 
EVENTS OF DEFAULT
 
     Unless otherwise specified in the related Prospectus Supplement, Events of
Default under each Agreement will generally consist of (i) any failure by the
Master Servicer to distribute or cause to be distributed to Certificateholders
of any class any required payment (other than an Advance) which continues
unremedied for five business days after the giving of written notice of such
failure to the Master Servicer by the Trustee or the Depositor, or to the Master
Servicer, the Depositor and the Trustee by the holders of Certificates of such
class evidencing not less than 25% of the related Trust Fund (based on the
outstanding principal balances of the Certificates); (ii) any failure by the
Master Servicer to make an Advance as required under the Agreement, unless cured
as specified therein; (iii) any failure by the Master Servicer duly to observe
or perform in any material respect any of its other covenants or agreements in
the Agreement which continues unremedied for sixty days after the giving of
written notice of such failure to the Servicer by the Trustee or the Depositor,
or to the Master Servicer, the Depositor and the Trustee by the holders of
Certificates evidencing not less than 25% of the related Trust Fund (based on
the outstanding principal balances of the Certificates); and (iv) certain events
of insolvency, readjustment of debt, marshaling of assets and liabilities or
similar proceeding and certain actions by or on behalf of the Master Servicer
indicating its insolvency, reorganization or inability to pay its obligations.
 
     If specified in the related Prospectus Supplement, the Agreement will
permit the Trustee to sell the Mortgage Assets and the other assets of the Trust
Fund in the event that payments in respect thereto are insufficient to make
payments required in the Agreement. The assets of the Trust Fund will be sold
only under the circumstances and in the manner specified in the related
Prospectus Supplement.
 
RIGHTS UPON EVENT OF DEFAULT
 
     So long as an Event of Default under an Agreement remains unremedied, the
Trustee may, and at the direction of holders of Certificates having not less
than 25% of the related Trust Fund (based on the outstanding principal balances
of the Certificates) and under such other circumstances as may be specified in
such Agreement, the Trustee shall, terminate all of the rights and obligations
of the Master Servicer under the Agreement relating to such Trust Fund and in
and to the Mortgage Loans, whereupon the Trustee will succeed to all of the
responsibilities, duties and liabilities of the Master Servicer under the
Agreement, including, if specified in the related Prospectus Supplement, the
obligation to make advances, and will be entitled to similar compensation
arrangements. In the event that the Trustee is unwilling or unable so to act, it
may appoint, or petition a court of competent jurisdiction for the appointment
of, a Mortgage Loan servicing institution with a net worth of at least
$10,000,000 to act as successor to the Master Servicer under the
                                       49
<PAGE>   168
 
Agreement. Pending such appointment, the Trustee is obligated to act in such
capacity. The Trustee and any such successor may agree upon the servicing
compensation to be paid, which in no event may be greater than the compensation
payable to the Master Servicer under the Agreement.
 
     No Certificateholder, solely by virtue of such holder's status as a
Certificateholder, will have any right under any Agreement to institute any
proceeding with respect to such Agreement, unless such holder previously has
given to the Trustee written notice of default and unless the holders of
Certificates of any Class of such Series evidencing not less than 25% of the
related Trust Fund (based on the outstanding principal balances of the
Certificates) have made written request upon the Trustee to institute such
proceeding in its own name as Trustee thereunder and have offered to the Trustee
reasonable indemnity, and the Trustee for 60 days has neglected or refused to
institute any such proceeding.
 
AMENDMENT
 
     Unless otherwise specified in the related Prospectus Supplement, each
Agreement may be amended by the Depositor, the Master Servicer and the Trustee,
without the consent of any of the Certificateholders, (i) to cure any ambiguity
or mistake; (ii) to correct or supplement any provision therein which may be
defective or inconsistent with any other provision therein or with the related
Prospectus Supplement or Prospectus or to correct any error or mistake; (iii) to
obtain, maintain or improve the rating of any class of Certificates (it being
understood that after obtaining any rating required at the initial issuance of
the related Series, none of the Depositor, Master Servicer or Trustee is
obligated to obtain, maintain or improve the rating of any class of Certificates
of such Series); or (iv) to make any other revisions with respect to matters or
questions arising under the Agreement which are not materially inconsistent with
the provisions thereof, provided that, in the case of clause (iv), such action
will not adversely affect in any material respect the interests of any
Certificateholder. An amendment will be deemed not to adversely affect in any
material respect the interests of the Certificateholders if the person
requesting such amendment obtains a letter from each rating agency requested to
rate the class or classes of Certificates of such Series stating that such
amendment will not result in the downgrading or withdrawal of the respective
ratings then assigned to such Certificates. In addition, to the extent provided
in the related Agreement, an Agreement may be amended without the consent of any
of the Certificateholders, to change the manner in which the Collection Account
is maintained, provided that any such change does not adversely affect the then
current rating on the class or classes of Certificates of such Series that have
been rated. In addition, if a REMIC election is made with respect to a Trust
Fund, the related Agreement may be amended to modify, eliminate or add to any of
its provisions to such extent as may be necessary to maintain the qualification
of the related Trust Fund as a REMIC, provided that the Trustee has received an
opinion of counsel to the effect that such action is necessary or helpful to
maintain such qualification.
 
     Unless otherwise specified in the related Prospectus Supplement, each
Agreement may also be amended by the Depositor, the Master Servicer and the
Trustee with consent of Holders of Certificates of such Series evidencing not
less than 51% of the aggregate Percentage Interests of each class affected
thereby for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Agreement or of modifying in any manner
the rights of the holders of the related Certificates; provided, however, no
such amendment may (i) reduce in any manner the amount of or delay the timing
of, payments received on Mortgage Loans which are required to be distributed on
any Certificate without the consent of the holder of such Certificate, or (ii)
reduce the aforesaid percentage of Certificates of any class of holders which
are required to consent to any such amendment without the consent of the holders
of all Certificates of such class covered by such Agreement then outstanding. If
a REMIC election is made with respect to a Trust Fund, the Trustee will not be
entitled to consent to an amendment to the related Agreement without having
first received an opinion of counsel to the effect that such amendment will not
cause such Trust Fund to fail to qualify as a REMIC.
 
TERMINATION; OPTIONAL TERMINATION
 
     Unless otherwise specified in the related Agreement, the obligations
created by each Agreement for each Series of Certificates will terminate upon
the payment to the related Certificateholders of all amounts held in
                                       50
<PAGE>   169
 
the Collection Account or by the Master Servicer and required to be paid to them
pursuant to such Agreement following the later of (i) the final payment or other
liquidation of the last of the Mortgage Assets subject thereto or the
disposition of all property acquired upon foreclosure of any such Mortgage
Assets remaining in the Trust Fund and (ii) the purchase by the Master Servicer,
the Depositor or, if REMIC treatment has been elected and if specified in the
related Prospectus Supplement, by the holder of the residual interest in the
REMIC (see "Certain Federal Income Tax Consequences" below), from the related
Trust Fund of all of the remaining Mortgage Assets and all property acquired in
respect of such Mortgage Assets.
 
     Unless otherwise specified in the related Prospectus Supplement, any such
purchase of Mortgage Assets and property acquired in respect of Mortgage Assets
evidenced by a Series of Certificates will be made at the option of the Master
Servicer, the Depositor or, if applicable, such holder of the REMIC residual
interest, at a price, and in accordance with the procedures, specified in the
related Prospectus Supplement. The exercise of such right will effect early
retirement of the Certificates of that Series, but the right of the Master
Servicer, the Depositor or, if applicable, such holder of the REMIC residual
interest, to so purchase is subject to the principal balance of the related
Mortgage Assets being less than the percentage specified in the related
Prospectus Supplement of the aggregate principal balance of the Mortgage Assets
at the Cut-off Date for the Series. The foregoing is subject to the provision
that if a REMIC election is made with respect to a Trust Fund, any repurchase
pursuant to clause (ii) above will be made only in connection with a "qualified
liquidation" of the REMIC within the meaning of Section 860F(a)(4) of the Code.
 
THE TRUSTEE
 
     The Trustee under each Agreement will be named in the applicable Prospectus
Supplement. The commercial bank or trust company serving as Trustee may have
normal banking relationships with the Depositor, the Master Servicer and any of
their respective affiliates.
 
CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
     The following discussion contains summaries, which are general in nature,
of certain legal matters relating to the Mortgage Loans. Because such legal
aspects are governed primarily by applicable state law (which laws may differ
substantially), the summaries do not purport to be complete nor to reflect the
laws of any particular state, nor to encompass the laws of all states in which
the security for the Mortgage Loans is situated. The summaries are qualified in
their entirety by reference to the appropriate laws of the states in which
Mortgage Loans may be originated.
 
GENERAL
 
     The Mortgage Loans will be secured by deeds of trust, mortgages, security
deeds or deeds to secure debt, depending upon the prevailing practice in the
state in which the property subject to the loan is located. Deeds of trust are
used almost exclusively in California instead of mortgages. A mortgage creates a
lien upon the real property encumbered by the mortgage, which lien is generally
not prior to the lien for real estate taxes and assessments. Priority between
mortgages depends on their terms and generally on the order of recording with a
state or county office. There are two parties to a mortgage, the mortgagor, who
is the borrower and owner of the mortgaged property, and the mortgagee, who is
the lender. Under the mortgage instrument, the mortgagor delivers to the
mortgagee a note or bond evidencing the loan and the mortgage. Although a deed
of trust is similar to a mortgage, a deed of trust formally has three parties,
the borrower-property owner called the grantor/trustor (similar to a mortgagor),
a lender called the beneficiary (similar to a mortgagee) and a third-party
grantee called the trustee. Under a deed of trust, the borrower grants the
property, irrevocably until the debt is paid, in trust, generally with a power
of sale, to the trustee to secure payment of the obligation. A security deed and
a deed to secure debt are special types of deeds which indicate on their face
that they are granted to secure an underlying debt. By executing a security deed
or deed to secure debt, the grantor conveys title to, as opposed to merely
creating a lien upon, the subject property to the grantee until such time as the
underlying debt is repaid. The trustee's authority under a deed of trust, the
mortgagee's authority under a mortgage and the grantee's authority under a
security deed or deed to secure debt are governed by law and, with respect to
some deeds of trust, the directions of the beneficiary.

HOME OWNERSHIP AND EQUITY PROTECTION ACT OF 1994
 
     Violations of certain provisions of these federal laws may limit the
ability of the Master Servicer to collect all or part of the principal of or
interest on the Mortgage Loans and in addition could subject the Trust Fund to
damages and administrative enforcement. The Mortgage Loans may be subject to the
Home Ownership and Equity Protection Act of 1994 ("Act") which amended the
Truth-in-Lending Act as it applies to mortgages subject to the Act. The Act
requires certain additional disclosures, specifies the timing of such
disclosures and limits or prohibits inclusion of certain provisions in mortgages
subject to the Act. The Act also provides that any purchaser or assignee of a
mortgage covered by the Act is subject to all of the claims and defenses which
the borrower could assert against the original lender. The maximum damages that
may be recovered under the Act from an assignee is the remaining amount of
indebtedness plus the total amount paid by the borrower in connection with the
mortgage loan. If the Trust Fund includes Mortgage Loans subject to the Act, it
will be subject to all of the claims and defenses which the borrower could
assert against a Seller. Any violation of the Act which would result in such
liability would be a breach of such Seller's representations and warranties, and
such Seller would be obligated to cure, repurchase or, if permitted by the
Agreement, substitute for the Mortgage Loan in question.
 
PREPAYMENT CHARGES
 
     Under certain state laws, prepayment charges may not be imposed after a
certain period of time following the origination of Mortgage Loans with respect
to prepayments on loans secured by liens encumbering owner-occupied residential
properties. Since many of the Mortgaged Properties will be owner-occupied, it is
anticipated that prepayment charges may not be imposed with respect to many of
the Mortgage Loans. The absence of such a restraint on prepayment, particularly
with respect to fixed rate Mortgage Loans having higher Mortgage Rates or APRs,
may increase the likelihood of refinancing or other early retirement of such
loans or contracts.
 
COOPERATIVES
 
     Certain of the Mortgage Loans may be Cooperative Loans. The Cooperative
owns all the real property that comprises the project, including the land,
separate dwelling units and all common areas. The Cooperative is directly
responsible for project management and, in most cases, payment of real estate
taxes and hazard and liability insurance. If there is a blanket mortgage on the
Cooperative and/or underlying land, as is generally the case, the Cooperative,
as project mortgagor, is also responsible for meeting these mortgage
obligations. A blanket mortgage is ordinarily incurred by the Cooperative in
connection with the construction or purchase of the Cooperative's apartment
building. The interest of the occupant under proprietary leases or occupancy
agreements to which that Cooperative is a party are generally subordinate to the
interest of the holder of the blanket mortgage in that building. If the
Cooperative is unable to meet the payment obligations arising under its blanket
mortgage, the mortgagee holding the blanket mortgage could foreclose on that
mortgage and terminate all subordinate proprietary leases and occupancy
agreements. In addition, the blanket mortgage on a Cooperative may provide
financing in the form of a mortgage that does not fully amortize with a
significant portion of principal being due in one lump sum at final maturity.
The inability of the Cooperative to refinance this mortgage and its consequent
inability to make such final payment could lead to foreclosure by the mortgagee
providing the financing. A foreclosure in either event by the holder of the
blanket mortgage could eliminate or significantly diminish the value of any
collateral held by the lender who financed the purchase by an individual
tenant-stockholder of Cooperative shares or, in the case of a Trust Fund
including Cooperative Loans, the collateral securing the Cooperative Loans.
 
     The Cooperative is owned by tenant-stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy agreements which confer exclusive rights to occupy specific
units. Generally, a tenant-stockholder of a Cooperative must make a monthly
payment to the Cooperative representing such tenant-stockholder's pro rata share
of the Cooperative's payments for its blanket mortgage, real property taxes,
maintenance expenses and other capital or ordinary expenses. An ownership
interest in a Cooperative and accompanying rights is financed through a
Cooperative share loan evidenced by a promissory note and secured by a security
interest in the occupancy agreement or
                                       52
<PAGE>   171
 
proprietary lease and in the related Cooperative shares. The lender takes
possession of the share certificate and a counterpart of the proprietary lease
or occupancy agreement and a financing statement covering the proprietary lease
or occupancy agreement and the Cooperative shares is filed in the appropriate
state and local offices to perfect the lender's interest in its collateral.
Subject to the limitations discussed below, upon default of the
tenant-stockholder, the lender may sue for judgment on the promissory note,
dispose of the collateral at a public or private sale or otherwise proceed
against the collateral or tenant-stockholder as an individual as provided in the
security agreement covering the assignment of the proprietary lease or occupancy
agreement and the pledge of Cooperative shares.
 
     With respect to Cooperative Loans, any prospective purchaser will generally
have to obtain the approval of the board of directors of the relevant
Cooperative before purchasing the shares and acquiring rights under the related
proprietary lease or occupancy agreement. This approval is usually based on the
purchaser's income and net worth and numerous other factors. Although the
Cooperative's approval is unlikely to be unreasonably withheld or delayed, the
necessity of acquiring such approval could limit the number of potential
purchasers for those shares and otherwise limit the Trust Fund's ability to sell
and realize the value of those shares.
 
     In general, a "tenant-stockholder" (as defined in Code Section 216(b)(2))
of a corporation that qualifies as a "cooperative housing corporation" within
the meaning of Code Section 216(b)(1) is allowed a deduction for amounts paid or
accrued within his taxable year to the corporation representing his
proportionate share of certain interest expenses and certain real estate taxes
allowable as a deduction under Code Section 216(a) to the corporation under Code
Sections 163 and 164. In order for a corporation to qualify under Code Section
216(b)(1) for its taxable year in which such items are allowable as a deduction
to the corporation, such Section requires, among other things, that at least 80%
of the gross income of the corporation be derived from its tenant-stockholders
(as defined in Code Section 216(b)(2)). By virtue of this requirement, the
status of a corporation for purposes of Code Section 216(b)(1) must be
determined on a year-to-year basis. Consequently, there can be no assurance that
Cooperatives relating to the Cooperative Loans will qualify under such Section
for any particular year. In the event that such a Cooperative fails to qualify
for one or more years, the value of the collateral securing any related
Cooperative Loans could be significantly impaired because no deduction would be
allowable to tenant-stockholders under Code Section 216(a) with respect to those
years. In view of the significance of the tax benefits accorded
tenant-stockholders of a corporation that qualifies under Code Section
216(b)(1), the likelihood that such a failure would be permitted to continue
over a period of years appears remote.
 
FORECLOSURE/REPOSSESSION
 
     Deed of Trust.  Foreclosure of a deed of trust is generally accomplished by
a non-judicial sale under a specific provision in the deed of trust which
authorizes the trustee to sell the property at public auction upon any default
by the borrower under the terms of the note or deed of trust. In certain states,
such foreclosure also may be accomplished by judicial action in the manner
provided for foreclosure of mortgages. In some states, such as California, the
trustee must record a notice of default and send a copy to the borrower-trustor,
to any person who has recorded a request for a copy of any notice of default and
notice of sale. In addition, the trustee must provide notice in some states to
any other individual having an interest of record in the real property,
including any junior lienholder. If the deed of trust is not reinstated within
any applicable cure period, a notice of sale must be posted in a public place
and, in most states, including California, published for a specified period of
time in one or more newspapers. In addition, these notice provisions require
that a copy of the notice of sale be posted on the property and sent to all
parties having an interest of record in the property. In California, the entire
process from recording a notice of default to a non-judicial sale usually takes
four to five months.
 
     In some states, including California, the borrower-trustor has the right to
reinstate the loan at any time following default until shortly before the
trustee's sale. In general, the borrower, or any other person having a junior
encumbrance on the real estate, may, during a reinstatement period, cure the
default by paying the entire amount in arrears plus the costs and expenses
incurred in enforcing the obligation. Certain state laws
 
                                       53
<PAGE>   172
 
control the amount of foreclosure expenses and costs, including attorney's fees,
which may be recoverable by a lender.
 
     Mortgages.  Foreclosure of a mortgage is generally accomplished by judicial
action. The action is initiated by the service of legal pleadings upon all
parties having an interest in the real property. Delays in completion of the
foreclosure may occasionally result from difficulties in locating necessary
parties. Judicial foreclosure proceedings sometimes are not contested by any of
the parties. 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 a judicial foreclosure proceeding, the court generally issues a
judgment of foreclosure and appoints a referee or other court officer to conduct
the sale of the property. In general, the borrower, or any other person having a
junior encumbrance on the real estate, may, during a statutorily prescribed
reinstatement period, cure a monetary default by paying the entire amount in
arrears plus other designated costs and expenses incurred in enforcing the
obligation. Generally, state law controls the amount of foreclosure expenses and
costs, including attorney's fees, which may be recovered by a lender. After the
reinstatement period has expired without the default having been cured, the
borrower or junior lienholder no longer has the right to reinstate the loan and
must pay the loan in full to prevent the scheduled foreclosure sale. If the deed
of trust is not reinstated, a notice of sale must be posted in a public place
and, in most states, published for a specific period of time in one or more
newspapers. In addition, some state laws require that a copy of the notice of
sale be posted on the property and sent to all parties having an interest in the
real property.
 
     Although foreclosure sales are typically public sales, frequently no third
party purchaser bids in excess of the lender's lien because of the absence of
equity in the property, the difficulty of determining the exact status of title
to the property, the possible deterioration of the property during the
foreclosure proceedings and a requirement that the purchaser pay to bid for the
property. Thus the foreclosing lender often purchases the property from the
trustee or referee for an amount equal to the principal amount outstanding under
the loan, accrued and unpaid interest and the expenses of foreclosure.
Thereafter, subject to the right of the borrower in some states to remain in
possession during the redemption period, the lender will assume the burden of
ownership, including obtaining hazard insurance and making such repairs at its
own expense as are necessary to render the property suitable for sale. The
lender will commonly obtain the services of a real estate broker and pay the
broker's commission in connection with the sale of the property. Depending upon
market conditions, the ultimate proceeds of the sale of the property may not
equal the lender's investment in the property. Any loss may be reduced by the
receipt of mortgage insurance proceeds, if any, or by judicial action against
the borrower for the deficiency, if such action is permitted by law.
 
     Courts have imposed general equitable principles upon foreclosure. These
equitable principles are generally designed to relieve the borrower from the
legal effect of his defaults under the loan documents. Examples of judicial
remedies that have been fashioned include judicial requirements that the lender
undertake affirmative and expensive actions to determine the causes for the
borrower's default and the likelihood that the borrower will be able to
reinstate the loan. In some cases, courts have substituted their judgment for
the lender's judgment and have required that lenders reinstate loans or recast
payment schedules in order to accommodate borrowers who are suffering from
temporary financial disability. In other cases, courts have limited the right of
the lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower failing adequately to maintain the property or
the borrower executing a second security instrument affecting the property. Some
courts have been faced with the issue of whether federal or state constitutional
provisions reflecting due process concerns for fair notice require that
borrowers under deeds of trust receive notice longer than that prescribed by
statute. For the most part, these cases have upheld the notice provisions as
being reasonable or have found that the sale by a trustee under a deed of trust
does not involve sufficient state action to afford constitutional protection to
the borrower.
 
     Home Equity Loans.  Since the Mortgages securing Home Equity Loans are
often junior liens subordinate to the rights of the mortgagee under the related
senior mortgage or mortgages, the proceeds from any liquidation, insurance or
condemnation proceedings will be available to satisfy the outstanding balance of
such junior mortgage only to the extent that the claims of such senior
mortgagees have been satisfied in full, including any related foreclosure costs.
In addition, a junior mortgagee may not foreclose on the property securing a
junior mortgage unless it forecloses subject to the senior mortgages, in which
case it must either pay
                                       54
<PAGE>   173
 
the entire amount due on the senior mortgages to the senior mortgagees at or
prior to the foreclosure sale or undertake the obligation to make payments on
the senior mortgages in the event the mortgagor is in default thereunder. The
Trust Fund will not have any source of funds to satisfy the senior mortgages to
make payments due to the senior mortgagees.
 
     Cooperative Loans.  The Cooperative shares owned by the tenant-stockholder
and pledged to the lender are, in almost all cases, subject to restrictions on
transfer as set forth in the Cooperative's certificate of incorporation and
by-laws, as well as the proprietary lease or occupancy agreement, and may be
canceled by the Cooperative for failure by the tenant-stockholder to pay rent or
other obligations or charges owed by such tenant-stockholder, including
mechanics' liens against the cooperative apartment building incurred by such
tenant-stockholder. The proprietary lease or occupancy agreement generally
permits the Cooperative to terminate such lease or agreement in the event an
obligor fails to make payments or defaults in the performance of covenants
required thereunder. Typically, the lender and the Cooperative enter into a
recognition agreement which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the Cooperative will recognize the
lender's lien against proceeds from the sale of the Cooperative apartment,
subject, however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the Cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the Cooperative Loan and accrued and unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan, the lender must obtain the approval or consent of the
Cooperative as required by the proprietary lease before transferring the
Cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with the provisions of Article 9 of the Uniform Commercial
Code (the "UCC") and the security agreement relating to those shares. Article 9
of the UCC requires that a sale be conducted in a "commercially reasonable"
manner. Whether a foreclosure sale has been conducted in a "commercially
reasonable" manner will depend on the facts in each case. In determining
commercial reasonableness, a court will look to the notice given the debtor and
the method, manner, time, place and terms of the foreclosure. Generally, a sale
conducted according to the usual practice of banks selling similar collateral
will be considered reasonably conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the Cooperative to receive sums due under the
proprietary lease or occupancy agreement. If there are proceeds remaining, the
lender must account to the tenant-stockholder for the surplus. Conversely, if a
portion of the indebtedness remains unpaid, the tenant-stockholder is generally
responsible for the deficiency. See "-- Anti-Deficiency Legislation and Other
Limitations on Lenders" below.
 
     In the case of foreclosure on a building which was converted from a rental
building to a building owned by a Cooperative under a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property subject
to rent control and rent stabilization laws which apply to certain tenants who
elected to remain in the building but who did not purchase shares in the
Cooperative when the building was so converted.
 
                                       55
<PAGE>   174
 
RIGHTS OF REDEMPTION
 
     In some states after sale pursuant to a deed of trust or foreclosure of a
mortgage, the borrower and certain foreclosed junior lienors are given a
statutory period in which to redeem the property from the foreclosure sale. In
certain other states, including California, this right of redemption applies
only to sales following judicial foreclosure, and not to sales pursuant to a
non-judicial power of sale. In most states where the right of redemption is
available, statutory redemption may occur upon payment of the foreclosure
purchase price, accrued interest and taxes. In some states, the right to redeem
is an equitable right. The effect of a right of redemption is to diminish the
ability of the lender to sell the foreclosed property. The exercise of a right
of redemption would defeat the title of any purchaser at a foreclosure sale, or
of any purchaser from the lender subsequent to judicial 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 LENDERS
 
     Certain states have imposed statutory restrictions that limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage. In some
states, including California, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure or sale under a deed of trust. A deficiency judgment is a personal
judgment against the borrower equal in most cases to the difference between the
amount due to the lender and the purchase price offered or paid for the property
at the time of the foreclosure sale net of certain expenses. As a result of
these prohibitions, it is anticipated that in most instances the Servicer will
utilize the non-judicial foreclosure remedy and will not seek deficiency
judgments against defaulting Mortgagors. In some states, exceptions to the
anti-deficiency statutes are provided for in certain instances where the value
of the lender's security has been impaired by acts or omissions of the borrower;
for example, in the event of waste of the property.
 
     Some state 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 borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security;
however, in some of these states, the lender, following judgment on such
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies with respect to the security. Consequently, the
practical effect of the election requirement, when applicable, is that lenders
will usually proceed first against the security rather than bringing a personal
action against the borrower.
 
     In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
the federal Soldiers' and Sailors' Civil Relief Act of 1940 and state laws
affording relief to debtors, may interfere with or affect the ability of the
secured mortgage lender to realize upon its security. For example, in a
proceeding under the federal Bankruptcy Code, a lender may not foreclose on the
Mortgaged Property without the permission of the bankruptcy court. The
rehabilitation plan proposed by the debtor may provide, if the Mortgaged
Property is not the debtor's principal residence and the court determines that
the value of the Mortgaged Property is less than the principal balance of the
mortgage loan, for the reduction of the secured indebtedness to the value of the
Mortgaged Property as of the date of the commencement of the bankruptcy,
rendering the lender a general unsecured creditor for the difference, and also
may reduce the monthly payments due under such mortgage loan, change the rate of
interest and alter the mortgage loan repayment schedule. The effect of any such
proceedings under the federal Bankruptcy Code, including but not limited to any
automatic stay, could result in delays in receiving payments on the Mortgage
Loans underlying a Series of Certificates and possible reductions in the
aggregate amount of such payments.
 
     The Mortgage Loans are also subject to federal laws, including:
 
          (i) the federal Truth-in-Lending Act and Regulation Z promulgated
     thereunder, which require certain disclosures to the borrowers regarding
     the terms of the Mortgage Loans;
 
                                       56
<PAGE>   175
 
          (ii) the Equal Credit Opportunity Act and Regulation B promulgated
     thereunder, which prohibit discrimination on the basis of age, race, color,
     sex, religion, marital status, national origin, receipt of public
     assistance or the exercise of any right under the Consumer Credit
     Protection Act, in the extension of credit;
 
          (iii) the Fair Credit Reporting Act, which regulates the use and
     reporting of information related to the borrower's credit experience; and
 
          (iv) the Home Ownership and Equity Protection Act of 1994.
 
     These and other federal and state consumer protection laws impose
substantive requirements upon mortgage lenders in connection with the
origination, servicing and enforcement of Mortgage Loans. Violations of certain
provisions of these laws may limit the ability of the Master Servicer to collect
all or part of the principal of or interest on the Mortgage Loans, may subject
the Master Servicer to damages and administrative enforcement and in addition
could be raised by borrowers as a recoupment or setoff in a collection or
foreclosure action. The federal tax laws provide priority to certain tax liens
over the lien of a mortgage or secured party.
 
     Generally, Article 9 of the UCC governs foreclosure on Cooperative shares
and the related proprietary lease or occupancy agreement and foreclosure on the
beneficial interest in a land trust. Some courts have interpreted section 9-504
of the UCC to prohibit a deficiency award unless the creditor establishes that
the sale of the collateral (which, in the case of a Cooperative Loan, would be
the shares of the Cooperative and the related proprietary lease or occupancy
agreement) was conducted in a commercially reasonable manner.
 
ENVIRONMENTAL RISKS
 
     Real property pledged as security to a lender may be subject to unforeseen
environmental risks. Under the laws of certain states, contamination of a
property may give rise to a lien on the property to assure the payment of the
costs of clean-up. In several states such a lien has priority over the lien of
an existing mortgage against such property. In addition, under the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended ("CERCLA"), the United States Environmental Protection Agency ("EPA")
may impose a lien on property where EPA has incurred clean-up costs. However, a
CERCLA lien is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and under CERCLA, it is conceivable that a
lender may be held liable, as an "owner" or "operator," for costs of addressing
releases or threatened releases of hazardous substances at a Mortgaged Property,
regardless of whether or not the environmental damage or threat was caused by a
prior owner or operator. CERCLA imposes liability on any and all "responsible
parties" (which includes, inter alia, the property owner and operator) for the
cost of clean-up of releases of hazardous substances. However, CERCLA excludes
from the definition of "owner or operator" secured creditors who hold indicia of
ownership for the purpose of protecting their security interest, but "without
participating in the management of the facility." That exclusion was
substantially narrowed by a May 1990 decision of the United States Court of
Appeals for the Eleventh Circuit in United States v. Fleet Factors Corp., which
held that a lender need not have involved itself in the day-to-day operations of
the facility or participated in decisions relating to hazardous waste management
in order to be liable; rather, liability could attach to the lender if its
involvement with the management of the facility is broad enough to support the
inference that the lender could affect hazardous waste management practices if
it so chose. The court added that a lender's capacity to influence such
decisions could be inferred from the extent of its involvement in the facility's
financial management. In response to Fleet Factors, EPA promulgated regulations
designed to clarify the range of activities a lender may engage in without
losing the benefit of the statutory exclusion. Under the regulations, which took
effect in April 1992, a lender is permitted to monitor the borrower's
environmental practices in order to determine if the facility is in compliance
with applicable law, and to require the borrower to take measures necessary to
achieve or maintain compliance or conduct necessary clean-ups. The lender may
not, however, exercise control over or assume responsibility for the borrower's
environmental practices. Such actions would be considered "participation in the
management of the facility." Also, if the lender takes title to or possession of
the property, it might be deemed to have obviated the security interest
exclusion and to be liable for clean-up
                                       57

costs pursuant to CERCLA. The EPA regulations allow lenders to take certain
actions with respect to foreclosure, without losing the benefit of the statutory
exclusion. Essentially, the regulations allow the lender to take actions
consistent with protecting its security interest, but not actions which
demonstrate an intent to exercise long-term ownership interest in the property.
While the EPA regulations offer some protection to lenders, it must be noted
that such protection may not be available under applicable state law.
Furthermore, the regulations are binding only on EPA with respect to EPA's
enforcement powers and cost recovery rights. It has not yet been determined
whether the federal courts will apply the regulations in cost recovery actions
brought against lenders by other responsible parties, although the regulations
may well be considered persuasive by the courts. (Two judicial challenges have
been brought against the EPA regulations in the United States Court of Appeals
for the District of Columbia Circuit. The challenges both allege that the
regulations are inconsistent with the statutory requirements of CERCLA and,
therefore, should be invalidated. The challenges were filed on July 28, 1992,
and are still pending.) If a lender is or becomes liable, it can bring an action
for contribution against any other "responsible parties," including a previous
owner or operator, who created the environmental hazard, but those persons or
entities may be bankrupt or otherwise judgment proof. The costs associated with
environmental clean-up may be substantial. It is conceivable that such remedial
costs arising from the circumstances set forth above would become a liability of
the Trust Fund and occasion a loss to Certificateholders.
 
     Court decisions have taken varying views of the scope of the
secured-creditor exemption, leading to administrative and legislative efforts to
provide guidance to lenders on the scope of activities that would trigger CERCLA
and/or RCRA liability. Until recently, these efforts have failed to provide
substantial guidance.
 
     On September 30, 1996, however, the President signed into law legislation
intended to clarify the scope of the secured-creditor exemption under both
CERCLA and RCRA. This legislation more explicitly defined the kinds of
"participation in management" that would trigger liability under CERCLA and
specified certain activities that would not constitute "participation in
management" or otherwise result in a forfeiture of the secured-creditor
exemption prior to foreclosure or during a workout period. The legislation also
clarifies the extent of protection against liability under CERCLA in the event
of foreclosure. The legislation also authorizes certain regulatory
clarifications of the scope of the secured-creditor exemption for purposes of
the Recourse Conservation and Recovery Act similar to the statutory protections
under CERCLA. However, since the courts have not yet had the opportunity to
interpret the new statutory provisions, the scope of the additional protections
offered by the Asset Conservation Act is not fully defined. It also is important
to note that the Asset Conservation Act does not offer complete protection to
lenders and that the risk of liability remains.
 
     Except as otherwise specified in the applicable Prospectus Supplement, at
the time the Mortgage Loans were originated, no environmental assessment or a
very limited environmental assessment of the Mortgaged Properties was conducted.
 
DUE-ON-SALE CLAUSES
 
     Unless otherwise provided in the related Prospectus 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 placed substantial restriction on
the right of lenders to enforce such clauses in many states. For instance, the
California Supreme Court in August 1978 held that due-on-sale clauses were
generally unenforceable. However, the Garn-St Germain Depository Institutions
Act of 1982 (the "Garn-St Germain Act"), subject to certain exceptions, preempts
state constitutional, statutory and case law prohibiting the enforcement of
due-on-sale clauses. As to loans secured by an owner-occupied residence, the
Garn-St Germain Act sets forth nine specific instances in which a mortgagee
covered by the Act may not exercise its rights under a due-on-sale clause,
notwithstanding the fact that a transfer of the property may have occurred. The
inability to enforce a due-on-sale clause may result in transfer of the related
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.
                                       58
<PAGE>   177
 
PREPAYMENT CHARGES
 
     Under certain state laws, prepayment charges may not be imposed after a
certain period of time following the origination of Mortgage Loans with respect
to prepayments on loans secured by liens encumbering owner-occupied residential
properties. Since many of the Mortgaged Properties will be owner-occupied, it is
anticipated that prepayment charges may not be imposed with respect to many of
the Mortgage Loans. The absence of such a restraint on prepayment, particularly
with respect to fixed-rate Mortgage Loans having higher Mortgage Rates or APRs,
may increase the likelihood of refinancing or other early retirement of such
loans or contracts.
 
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 Master Servicer to
collect full amounts of interest on certain of the Mortgage Loans. Unless
otherwise provided in the applicable Prospectus Supplement, any shortfall in
interest collections resulting from the application of the Relief Act could
result in losses to the holders of the Certificates. In addition, the Relief Act
imposes limitations which would impair the ability of the Master Servicer to
foreclose on an affected Mortgage Loan during the borrower's period of active
duty status. 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.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following summary represents the advice of Moore & Van Allen, PLLC,
counsel to the Depositor, as to the anticipated material federal income tax
consequences of the purchase, ownership and disposition of Certificates. The
summary is based on the provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), the regulations promulgated thereunder, including, where
applicable, proposed regulations and, in particular, regulations promulgated
under the REMIC provisions of the Code (the "REMIC Regulations"), judicial and
administrative rulings and decisions now in effect, all of which are subject to
change, possibly with retroactive effect. The summary does not purport to
address all aspects of federal income taxation that may affect particular
investors in view of their individual circumstances, including investors that
may be subject to special treatment under the federal income tax laws, such as
banks and insurance companies. In addition, the discussion is addressed
primarily to investors who will hold Certificates as "capital assets" within the
meaning of Section 1221 of the Code. The tax consequences to an investor from an
investment in Certificates will depend in part on the status or individual tax
circumstances of the investor. Accordingly, prospective investors are urged to
consult their tax advisors regarding the particular federal, state, local and
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 Trust Fund relating to a
particular Series of Certificates as one or more REMICs under the Code. The
Prospectus Supplement for each Series of Certificates will specify whether a
REMIC election will be made.
 
NON-REMIC CERTIFICATES; TAX STATUS AS A GRANTOR TRUST
 
     If a REMIC election is not made for a Trust Fund which relates to a
particular Series of Certificates, Moore & Van Allen, PLLC will deliver its
opinion that the Trust Fund will not be classified as an association taxable as
a corporation, but will be classified as a grantor trust under subpart E, Part I
of subchapter J of the Code, and that owners of Certificates issued by a
particular Trust Fund will be subject to federal income taxation as owners of
their pro rata share of the Trust Fund's assets. Unless otherwise specified, for
purposes of the discussion below relating to non-REMIC Certificates, the term
"Mortgage Loan" includes Mortgage Loans and mortgages underlying Agency
Securities and other Mortgage Assets owned by a Trust Fund.
 
SINGLE CLASS OF SENIOR CERTIFICATES
 
     Characterization.  A Trust Fund may be created with one class of Senior
Certificates and one class of Subordinated Certificates. In such case, each
Senior Certificateholder will be treated as the owner of a pro rata undivided
interest in the interest and principal portions of the Trust Fund represented by
that Senior Certificate and will be considered the equitable owner of a pro rata
undivided interest in each of the assets 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 Assets in the Trust Fund 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 Master Servicer in accordance with such Senior Certificateholder's method
of accounting. Under Code Section 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 Master Servicer, provided that such amounts are reasonable
compensation for services rendered to the Trust Fund. A Senior Certificateholder
that is an individual, estate or trust will be entitled to deduct its 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
Master 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 Master Servicer, whichever is earlier. If the
Servicing Fees paid to the Master Servicer were deemed to exceed reasonable
servicing compensation, the amount of such excess could be considered as a
retained ownership interest by the Master Servicer (or any person to whom the
Master 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.
 
     If specified in the related Prospectus Supplement, as to each Series of
Certificates, Moore & Van Allen, PLLC will render its opinion 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); to the extent that the Mortgage Loans represented by
     that Senior Certificate are of a type described in such Code section;
 
                                       60
<PAGE>   179
 
          (ii) 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)(4)(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); to the extent that the Mortgage Loans
     represented by that Senior Certificate are of a type described in such Code
     section;
 
          (iii) a Senior Certificate owned by a REMIC will be an "obligation
     which is principally secured by an interest in real property" within the
     meaning of Code Section 860G(a)(3); to the extent that the Mortgage Loans
     represented by that Senior Certificate consist of "qualified mortgages"
     within the meaning of such Code section; and
 
          (iv) a Senior Certificate owned by a "financial asset securitization
     investment trust" within the meaning of Code Section 860L(c) will be
     considered to represent "permitted assets" within the meaning of Code
     Section 860L(c); to the extent that the Mortgage Loans represented by that
     Senior Certificate consist of "debt instruments" or other permitted assets
     within the meaning of Code Section 860L(c).
 
     Buydown Mortgage Loans.  The assets constituting certain Trust Funds 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 Trust Fund 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 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
                                       61
<PAGE>   180
 
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. Original issue discount generally must be
reported as ordinary gross income as it accrues under a constant interest
method. See "Offered Certificates Representing Interests in Loans Other Than
ARMs -- Accrual of Original Issue Discount" 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, any
market discount would be equal to 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. Pursuant to certain de minimis rules
applicable to the computation of market discount, 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. The Treasury
Department has not yet issued any such regulations; however, the relevant
legislative history provides the best guidance applicable to this situation.
Under certain analogous rules set forth in the Code and pursuant to the
legislative history, the holder of such 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
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 yet been issued, it is not possible 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 acquires 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
any indebtedness incurred or maintained to purchase or carry the Senior
Certificate in excess of the aggregate amount of interest (including original
issue discount) includable 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 includable in income. The amount of any remaining
deferred deduction is to be taken into account
                                       62
<PAGE>   181
 
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 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 created. If a Trust Fund 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 Offered
Certificates will represent the right to some or all of the interest on all or a
portion of such Loans (the "Stripped Coupon Certificates") (collectively, the
Stripped Bond Certificates and the Stripped Coupon Certificates are referred to
as the "Stripped Certificates").
 
     Certain IRS guidance suggests that a servicing fee in excess of reasonable
servicing ("excess servicing") will be characterized under the stripped bond
rules. In such case, this guidance would appear to require that reasonable
servicing be calculated on a Mortgage Loan by Mortgage Loan basis which could
result in some Mortgage Loans being treated as having more than 100 basis points
of interest (i.e., 1% interest on the Mortgage Loan principal balance) stripped
off. However, if the Certificates are initially sold with a de minimis discount
(assuming no prepayment assumption is required), any non-de minimis discount
arising from a subsequent transfer of the Certificates should be treated as
market discount. See -- Non-REMIC Certificates; Tax Status as a Grantor Trust,"
and " -- Single Class of Senior Certificates -- Market Discount" herein.
 
     Under the Treasury Regulations issued December 28, 1992, a Stripped Bond
Certificate is generally 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"
and "-- 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 Trust Fund's Mortgage Loans.
 
     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. Certain IRS guidance
would appear to suggest that a Stripped Coupon Certificate be treated as a
single installment obligation subject to the original issue discount rules of
the Code. Under this characterization, 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
 
                                       63
<PAGE>   182
 
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.
 
     As an alternative to the method described above, the fact that some or all
of the interest payments with respect to the Stripped Certificates will not be
made if the Mortgage Loans are prepaid could lead to the interpretation that
such interest payments are "contingent" within the meaning of the OID
Regulations. The OID Regulations, as they relate to the treatment of contingent
interest, are by their terms not applicable to prepayable securities such as the
Stripped Certificates. However, if final regulations dealing with contingent
interest with respect to the Stripped Certificates apply the same principles as
the OID Regulations, such regulations may lead to different timing of income
inclusion than would be the case under the OID Regulations for noncontingent
debt instruments. Furthermore, application of such principles could lead to the
characterization of gain on the sale of contingent interest Stripped
Certificates as ordinary income.
 
     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, as noted below,
provide beneficial treatment to certain taxpayers that invest in mortgage loans
of the type that would typically make up a Trust Fund. With respect to these
Code sections, there is no specific legal authority specifying whether the
character of Senior Certificates issued in connection with the issuance of a
multiple class of Senior Certificates will necessarily be treated the same as
that of the underlying Mortgage Loans for purposes of these provisions. For
example, while Code Section 1286 treats a stripped obligation as a separate
obligation for purposes of the Code provisions addressing original issue
discount, as described above, there is some uncertainty whether such
characterization would necessarily apply with regard to other Code sections.
Nevertheless, unless otherwise specified in the related Prospectus Supplement,
as to each class of Senior Certificates, Moore & Van Allen, PLLC will render its
opinion that, although the issue is not free from doubt, based on policy
considerations, each class of Senior Certificates should be considered to
represent "real estate assets" within the meaning of Code Section 856(c)(4)(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. In addition, such opinion will opine that Senior
Certificates will be "obligation[s] (including any participation or certificate
of beneficial ownership therein) which [are] principally secured by an interest
in real property" within the meaning of Code Section 860G(a)(3) and "permitted
assets" within the meaning of Code Section 860L(c).
 
OFFERED CERTIFICATES REPRESENTING INTERESTS IN LOANS OTHER THAN ARMS
 
     Original issue discount on a Senior Certificate representing an interest in
a Mortgage Loan 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. 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." The following discussion is based in part on Treasury regulations
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").
 
     In general, under the Code, original issue discount is equal to the excess
of a debt instrument's stated redemption price at maturity over its issue price.
The issue price of a debt instrument as to any purchaser is generally equal to
the price paid by such purchaser for the debt instrument. The stated redemption
price at maturity of a debt instrument is the sum of all payments to be made on
such debt instrument other than payments that are treated as qualified stated
interest payments. The accrual of original issue discount on a Senior
Certificate representing an interest in Mortgage Loans, as described below under
"Accrual of Original
 
                                       64
<PAGE>   183
 
Issue Discount," will, unless otherwise specified in the related Prospectus
Supplement, utilize the original yield to maturity of the Senior Certificate to
compute any original issue discount, as calculated based on a reasonable assumed
prepayment rate for the Mortgage Loans underlying the Senior Certificate (the
"Prepayment Assumption"), and taking into account events that occur during the
calculation period. The Prepayment Assumption is required to be determined in
the manner prescribed by regulations, which regulations 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 such Certificate will
prepay at the Prepayment Assumption or at any other rate. Although the existing
authority literally only apply to debt instruments collateralized by mortgages
that are subject to prepayment rather than direct ownership interests, such as
the Senior Certificates, in mortgages, because no other legal authority provides
guidance with regard to the proper method for accruing original issue discount
on obligations that are subject to prepayment, until Treasury regulations or
other legal authority instructs otherwise, the Master Servicer intends to
calculate, and report original issue discount 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 original issue discount on such Senior Certificate for
each day on which it owns a Senior Certificate, including the date of purchase
but excluding the date of disposition. In the case of an original owner, the
daily portions of original issue discount with respect to each component
generally will be determined as follows under the existing authority. A
calculation will be made by the Master Servicer or such other entity specified
in the related Prospectus Supplement of the portion of original issue discount
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 Certificate (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 original issue discount
allocable to that accrual period reduced by the amount of any payment made at
the end of or during that accrual period. The original issue discount accruing
during such 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 period. With respect to an initial accrual period shorter than a full
monthly accrual period, the daily portions of original issue discount must be
determined according to an appropriate allocation under any reasonable method.
 
SENIOR CERTIFICATES REPRESENTING INTERESTS IN ARM LOANS
 
     The OID Regulations do not address the treatment of instruments, such as
the Senior Certificates, 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 stripping rules with respect to
such instruments. In the absence of any authority the Master 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 ARMs" 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 ("Deferred Interest") to the principal balance of an ARM Loan may
require the inclusion of such amount in the income of the Senior
Certificateholder when such amount accrues. Furthermore, the addition of
Deferred Interest to the Senior
 
                                       65
<PAGE>   184
 
Certificate's principal balance will result in additional income (including
possibly original issue discount income) to the Senior 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 includable
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 will be considered "portfolio
interest" and 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 beneficial ownership
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).
 
     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 is includable in gross income for federal income tax purposes
regardless of source.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The Master 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
 
     A Trust Fund 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" and "-- Prohibited Transactions and
Other Taxes"), if a Trust Fund 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 Trust
Fund will not be treated as a REMIC for such year and thereafter. In that event,
such entity may be taxable as a separate corporation, 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 status as a
REMIC, 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 Trust Fund that elects REMIC
status, Moore & Van Allen, PLLC will deliver its opinion generally to the effect
that, under then existing law and assuming compliance with all provisions of the
related Agreement, such Trust Fund 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 related
Prospectus Supplement for each Series of Certificates will indicate whether the
Trust Fund 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
"domestic building and loan association" will constitute assets described in
Code Section 7701(a)(19)(C); (ii) Certificates held by a real estate investment
trust will constitute "real estate assets" within the meaning of Code Section
856(c)(4)(A); and (iii) interest on Certificates held by a real estate
investment trust 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
considered to be real estate assets for purposes of Code Section 856(c).
 
     In some instances the Mortgage Loans may not be treated entirely as assets
described in the foregoing sections. See, in this regard, the discussion of
Buydown Mortgage Loans contained in "Non-REMIC Certificates" and "Single Class
of Senior Certificates" above. REMIC Certificates held by a real estate
investment trust will not constitute "Government Securities" within the meaning
of Code Section 856(c)(4)(A), and REMIC Certificates held by a regulated
investment company will not constitute "Government Securities" within the
meaning of Code Section 851(b)(4)(A)(ii). REMIC Certificates held by certain
financial institutions will constitute "evidences of indebtedness" within the
meaning of Code Section 582(c)(1). Regular Certificates will represent
"qualified mortgages," within the meaning of Code Section 860(G)(a)(3), for
other REMICs and "permitted assets," within the meaning of Code Section 860L(c),
for financial asset securitization investment trusts.
 
     Tiered REMIC Structures.  For certain Series of Certificates, two or more
separate elections may be made to treat designated portions of the related Trust
Fund as REMICs (respectively, the "Subsidiary REMIC or REMICs" and the "Master
REMIC") for federal income tax purposes. Upon the issuance of any such Series of
Certificates, Moore & Van Allen, PLLC, counsel to the Depositor, will deliver
its opinion generally to the effect that, assuming compliance with all
provisions of the related Agreement, the Master REMIC as well as any Subsidiary
REMIC or REMICs will each qualify as a REMIC and the REMIC Certificates issued
by the Master REMIC and the Subsidiary REMICs, respectively, will be considered
to evidence ownership of Regular Certificates or Residual Certificates in the
related REMIC within the meaning of the REMIC provisions.
 
                                       67
<PAGE>   186
 
     The Subsidiary REMIC or REMICs and the Master REMIC will be treated as one
REMIC solely for purposes of determining whether the REMIC Certificates will be
(i) "real estate assets" within the meaning of Section 856(c)(4)(A) of the Code;
(ii) "loans secured by an interest in real property" under Section
7701(a)(19)(C) of the Code; and (iii) 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.  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, in advance of receipt of
the cash attributable to such income. The following discussion is based in part
on the OID Regulations and the 1986 Act. The holder of a Regular Certificate
should be aware, however, that the OID Regulations do not currently 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 is required to 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
Prospectus 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, if any, of its "stated redemption price at maturity" over its "issue
price." The issue price of a Regular Certificate will generally be the first
price at which a substantial amount of Regular Certificates of that class are
first sold to the public (excluding bond houses, brokers, underwriters or
wholesalers). The issue price of a Regular Certificate also will include the
amount paid by an initial Regular Certificateholder, if any, 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
will equal all payments to be made on the Certificate other than payments which
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 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 either longer or shorter
than the interval between subsequent Distribution Dates, all or part of the
interest foregone, in the case of the longer interval, and all of the additional
interest, in the case of the shorter interval, will be included in the stated
redemption price at maturity and tested under the de minimis rule described
below. The OID Regulations suggest that all interest on a long first period
Regular Certificate that is issued with non-de
                                       68
<PAGE>   187
 
minimis OID may be treated as OID. 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 Prepayment Assumption.
The Prepayment Assumption with respect to a Series of Regular Certificates will
be set forth in the related Prospectus 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. However,
accrual method holders may elect to accrue all de minimis OID as well as market
discount under a constant interest method.
 
     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
stated periodic 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 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 may 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 excess of (a) the
purchaser's adjusted basis in the Regular Certificate immediately after the
purchase thereof over (b) the adjusted issue price of the Regular Certificate,
and the denominator of which is the
 
                                       69
<PAGE>   188
 
excess of (c) all amounts remaining to be paid on the Regular Certificate, other
than qualified stated interest, over (d) the adjusted issue price of the Regular
Certificate.
 
     Acquisition Premium.  A purchaser of a Regular Certificate at a price
greater than its adjusted issue price but less than its redemption price at
maturity will be required to include in gross income the daily portions of the
original issue discount on the Regular Certificate reduced pro rata by a
fraction, the numerator of which is the excess of its purchase price over such
adjusted issue price and the denominator of which is the excess of the remaining
stated redemption price at maturity over the adjusted issue price.
Alternatively, such a subsequent purchaser may elect to treat all such
acquisition premium under the "constant yield method."
 
     Variable Rate Regular Certificate.  Regular Certificates may provide for
interest based on a variable rate. Under the OID Regulations, 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,
and (ii) the interest compounds or is payable at least annually at current
values of (a) one or more "qualified floating rates," (b) a single fixed rate
and one or more qualified floating rates, (c) a single "objective rate," or (d)
a single fixed rate and a single objective rate that is a "qualified inverse
floating rate." A floating rate is a qualified floating rate if variations in
the rate can reasonably be expected to measure contemporaneous variations in the
cost of newly borrowed funds, where such rate is subject to a multiple of not
less than zero nor more than 1.35. Such rate may also be increased or decreased
by a fixed spread or subject to a fixed cap or floor, or a cap or floor that is
not reasonably expected as of the issue date to affect the yield of the
instrument significantly. An objective rate is any rate (other than a qualified
floating rate) that is determined using a single fixed formula and that is based
on objective financial or economic information, provided that such information
is not (i) within the control of the issuer or a related party or (ii) unique to
the circumstances of the issuer or a related party. A qualified inverse floating
rate is a rate equal to a fixed rate minus a qualified floating rate that
inversely reflects contemporaneous variations in the cost of newly borrowed
funds; an inverse floating rate that is not a qualified inverse floating rate
may nevertheless be an objective rate. A class of Regular Certificates may be
issued that does not have a variable rate under the foregoing rules; for
example, a class that bears different rates at different times during the period
it is outstanding such that it is considered significantly "front-loaded" or
"back-loaded" within the meaning of the OID Regulations. It is possible that
such a class may be considered to bear "contingent interest" within the meaning
of the OID Regulations. The OID Regulations, as they relate to the treatment of
contingent interest, are by their terms not applicable to Regular Certificates.
However, if final regulations dealing with contingent interest with respect to
Regular Certificates apply the same principles as the proposed OID Regulations,
such regulations may lead to different timing of income inclusion than would be
the case under the OID Regulations for noncontingent debt instruments.
Furthermore, application of such principles could lead to the characterization
of gain on the sale of contingent interest Regular Certificates as ordinary
income.
 
     Under the REMIC Regulations, a Regular Certificate (i) bearing a rate that
qualifies as a variable rate under the OID Regulations that is tied to current
values of a variable rate (or the highest, lowest or average of two or more
variable rates, including a rate based on the average cost of funds of one or
more financial institutions), or a positive or negative multiple of such a rate
(plus or minus a specified number of basis points), or that represents a
weighted average of rates on some or all of the Mortgage Loans, including such a
rate that is subject to one or more caps or floors, or (ii) bearing one or more
such variable rates for one or more periods, or one or more fixed rates for one
or more periods, and a different variable rate or fixed rate for other periods,
qualifies as a regular interest in a REMIC. Accordingly, unless otherwise
indicated in the applicable Prospectus Supplement, the Depositor intends to
treat Regular Certificates that qualify as regular interests under this rule in
the same manner as obligations bearing a variable rate for original issue
discount reporting purposes.
 
     The amount of original issue discount with respect to a Regular Certificate
bearing a variable rate of interest will accrue in the manner described above
under "-- Original Issue Discount," with the yield to maturity and future
payments on such Regular Certificate generally to be determined by assuming that
interest will be payable for the life of the Regular Certificate based on the
initial rate (or, if different, the value of the applicable variable rate as of
the pricing date) for the relevant class. Unless otherwise specified in the
applicable Prospectus Supplement, the Depositor intends to treat such variable
interest as qualified stated
                                       70
<PAGE>   189
 
interest, other than variable interest on an interest-only or super-premium
class, which will be treated as non-qualified stated interest includable in the
stated redemption price at maturity. Ordinary income reportable for any period
will be adjusted based on subsequent changes in the applicable interest rate
index.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Depositor intends to treat Regular Certificates bearing an interest rate that is
a weighted average of the net interest rates on Mortgage Loans as having
qualified stated interest. In the case of adjustable rate Mortgage Loans, the
applicable index used to compute interest on the Mortgage Loans in effect on the
pricing date (or possibly the issue date) will be deemed to be in effect
beginning with the period in which the first weighted average adjustment date
occurring after the issue date occurs. Adjustments will be made in each accrual
period either increasing or decreasing the amount of ordinary income reportable
to reflect the actual pass-through rate on the Regular Certificates.
 
     Market Discount.  A purchaser of a Regular Certificate may also be subject
to the market discount provisions of Code Sections 1276 through 1278. Under
these provisions and the principles applied by the OID Regulations in the
context of original issue discount, "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 income to the extent of
accrued market discount on such Regular Certificate upon receipt of each
distribution representing stated redemption price at maturity. 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 the accrual 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 is 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 "-- 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 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.
 
                                       71
<PAGE>   190
 
     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 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 (a) the
total remaining market discount and (b) 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 that 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) includable 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 includable 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 that 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 under Code
Section 171 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 may provide for
the accrual of interest when one or more Mortgage 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 Certificates 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
 
                                       72
<PAGE>   191
 
the latter analysis may result only in a slight difference in the timing of the
inclusion in income of interest on such Regular Certificates.
 
     Effects of Defaults and Delinquencies.  Certain Series of Certificates may
contain one or more Classes of Subordinate Certificates, and in the event there
are defaults or delinquencies on the Mortgage Loans, amounts that would
otherwise be distributed on the Subordinate Certificates may instead be
distributed on the Senior Certificates. Holders of Subordinate Certificates
nevertheless will be required to report income with respect to such Certificates
under an accrual method without giving effect to delays and reductions in
distributions on such Subordinate Certificates attributable to defaults and
delinquencies on the Mortgage Loans, except to the extent that it can be
established that such amounts are uncollectible. As a result, the amount of
income reported by a holder of a Subordinate Certificate in any period could
significantly exceed the amount of cash distributed to such holder in that
period. The holder will eventually be allowed a loss (or will be allowed to
report a lesser amount of income) to the extent that the aggregate amount of
distributions on the Subordinate Certificate is reduced as a result of defaults
and delinquencies on the Mortgage Loans. However, the law is unclear with
respect to the timing and character of such losses or reductions in income, and,
accordingly, Holders of Subordinate Certificates should consult their own tax
advisors on this point.
 
     Sale, Exchange or Redemption.  Upon the sale, exchange or redemption of a
Regular Certificate, the holder will recognize gain or loss equal to the
difference between the amount realized on such disposition, and the holder's
adjusted basis in the Regular Certificate. Such adjusted basis generally will
equal the cost of the Regular Certificate to the holder, increased by any
original issue discount and market discount included in the holder'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 holder and by any amortized premium. Except as provided in the
following paragraph and as provided under "-- Market Discount" above, 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 includable 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 includable in such holder's income.
 
     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 or
exchange of a Regular Certificate by a bank or a thrift institution to which
such section applies will be ordinary income or loss.
 
     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 require information relating to the
holder's purchase price which the REMIC may not have, it appears that the
information reports will only require information pertaining to the appropriate
proportionate method of accruing market discount.
 
     Non-Interest Expenses of the REMIC.  Under the REMIC regulations, if the
REMIC is considered to be a "single-class REMIC," a portion of the REMIC's
servicing, administrative and other non-interest expenses will be allocated as a
separate item to those Regular Certificateholders that are "pass-through
interest holders." Certificateholders that are "pass-through interest holders"
should consult their own tax advisors about the impact of these rules on an
investment in the Regular Certificates. See "Taxation of the
REMIC -- Pass-Through of Non-Interest Expenses of the REMIC" below.
 
     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 be considered "portfolio interest" and
will not be subject to federal withholding tax if (i) such Regular
Certificateholder does not actually or constructively
 
                                       73
<PAGE>   192
 
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 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 beneficial ownership
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.
 
     The IRS recently issued final regulations which would provide alternative
methods of satisfying the beneficial ownership certification requirement
described above. The final regulations are effective January 1, 2000, although
valid withholding certificates that are held on December 31, 1999, remain valid
until the earlier of December 31, 2000 or the due date of expiration of the
certificate under the rules currently in effect. The final regulations would
require, in the case of Regular Certificates held by a foreign partnership, that
(i) the certification described above be provided by the partners rather than by
the foreign partnership and (ii) the partnership provide certain information,
including a United States taxpayer identification number. A look-through rule
would apply in the case of tiered partnerships. Non-U.S. Persons should consult
their own tax advisors concerning the application of the certification
requirements in the final regulations.
 
     Further, it appears that a REMIC Regular Certificate would not be included
in the estate of a non-resident alien individual and would not be subject to
United States estate taxes. However, Certificateholders who are non-resident
alien individuals should consult their tax advisors concerning this question.
 
     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 doing so.
 
     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. 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.
 
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
 
                                       74
<PAGE>   193
 
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 assets of the Trust Fund 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. 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 such Residual Certificate would
have in the hands of an original Residual Certificateholder. See "-- Sale or
Exchange of Residual Certificates" below. It is not clear, however, whether such
adjustments will in fact be permitted or required and, if so, how they would be
made. The REMIC Regulations do not provide for any such adjustments.
 
     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
be subject to federal income tax in all events. Thus, for example, an excess
inclusion (i) may not be offset by any unrelated losses, deductions 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 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 Small Business Job Protection Act of 1996 has
eliminated the special rule permitting thrift institutions described in Code
Section 593 to use net operating losses and other allowable deductions to offset
their excess inclusion income from REMIC residual certificates that have
"significant value" within the meaning of the REMIC Regulations, effective for
taxable years beginning after December 31, 1995, except with respect to residual
certificates continuously held by a thrift institution since November 1, 1995.
 
     In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect of excess inclusions on the alternative minimum
taxable income of a residual holder. First, alternative minimum taxable income
for a residual holder is determined without regard to the special rule that
taxable income cannot be less than excess inclusions. Second, a residual
holder's alternative minimum taxable income for a tax year cannot be less than
excess inclusions for the year. Third, the amount of any alternative minimum tax
not operating loss deductions must be computed without regard to any excess
inclusions. These rules are effective for tax years beginning after December 31,
1986, unless a residual holder elects to have such rules apply only to tax years
beginning after August 20, 1996.
 
     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
 
                                       75
<PAGE>   194
 
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.
 
     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 distribution 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 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 yet to be issued, 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.
 
TAXATION OF THE REMIC
 
     General.  As noted above, although a REMIC is a separate entity for federal
income tax purposes, a REMIC is not generally subject to entity-level tax.
 
     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 "-- Pass-Through of 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
 
                                       76
<PAGE>   195
 
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 includable 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 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 "-- Sale or Exchange 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 only 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.
 
     Pass-Through of Non-Interest Expenses of the REMIC.  As a general rule, all
of the fees and 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 the 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 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 applicable Prospectus 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.
 
     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 or Residual Certificate directly or through a pass-through interest
holder 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 under Code Section 67 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,
Code Section 68 provides that
 
                                       77
<PAGE>   196
 
the amount of itemized deductions otherwise allowable for an individual whose
adjusted gross income exceeds a certain amount (the "Applicable Amount") will be
reduced by the lesser of (i) 3% of the excess of the individual's adjusted gross
income over the Applicable Amount or (ii) 80% of the amount of itemized
deductions otherwise allowable for the taxable year. The amount of additional
taxable income recognized by Residual Certificateholders who are subject to the
limitations of either Code Section 67 or Code Section 68 may be substantial.
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. 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.
 
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 includes 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, 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 Prospectus Supplement, such tax would be
borne first by the Residual Certificateholders, to the extent of amounts
distributable to them and then by the Master 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
REMICs final tax return a date on which such adoption is deemed to occur, and
sells all of its assets (other than cash) within a 90-day period beginning on
such date, the REMIC will not be subject to any prohibited transaction tax on
such sales, 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.
 
ADMINISTRATIVE MATTERS
 
     The REMIC's books must be maintained on a calendar year basis, and 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.
Treasury regulations provide that, except where there is a single residual
holder for an entire taxable year, the REMIC will be subject to the procedural
and administrative rules of the Code applicable to partnerships, including the
determination by the IRS of any adjustments to, among other things, items of
REMIC income, gain, loss, deduction, or credit in a unified administrative
proceeding.

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
the Residual Certificateholder's "excess inclusions." See "-- Residual
Certificates -- Excess Inclusions" herein.
 
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.
Treasury regulations provide that amounts distributed to Residual Holders may
qualify as "portfolio interest," subject to the conditions described in
"-- Regular Certificates -- Non-U.S. Persons" above, but only to the extent that
the Mortgage Loans were originated after July 18, 1984, and the Mortgage Loans
to which the Residual Certificates relate are in "registered form" within the
meaning of Section 163(f)(1) of the Code. In general, it is expected that
Mortgage Loans will not be, but regular interests in another REMIC will be,
treated as in registered form. Furthermore, the rate of withholding on any
income on a Residual Certificate that is excess inclusion income will not be
subject to reduction under any applicable tax treaties. See "-- Residual
Certificates -- Excess Inclusions." If the portfolio interest exemption is
unavailable, amounts paid 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 special restrictions on
the transfer of Residual Certificates, see "-- Tax-Related Restrictions on
Transfers of Residual Certificates" below.
 
     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 such acquisition.
 
         TAX-RELATED RESTRICTIONS ON TRANSFERS OF RESIDUAL CERTIFICATES
 
     Disqualified Organizations.  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 the REMIC regulations) equal to the present value of
the total anticipated "excess inclusions" with respect to such interest for
periods after the transfer and (ii) 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 from federal income taxes unless
 
                                       79
<PAGE>   198
 
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 not yet issued, 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.
 
     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 Master Servicer. The Master 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.
 
     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 below, if a 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 and any required or
permitted clean up calls or required liquidation provided for in the REMIC's
organizational documents, (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.
 
     Mark to Market Rules.  Prospective purchasers of a Residual Certificate
should be aware that the IRS recently finalized regulations under Code Section
475 which provide that any Residual Certificate acquired after January 3, 1995,
cannot be marked to market. Prospective purchasers of a Residual Certificate
should consult their tax advisors regarding the possible application of these
regulations.
 
     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," unless such transferee's income in
respect of the Residual Certificate is effectively connected with the conduct of
a United Sates trade or business. A Residual
 
                                       80
<PAGE>   199
 
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
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 IRS Form
4224 and the Trustee consents to such transfer in writing.
 
     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.
 
STATE, LOCAL AND OTHER TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described above in
"Certain Federal Income Tax Considerations," potential investors should consider
the state, local and other tax consequences relating to the acquisition,
ownership and disposition of the Certificates. State, local and other income tax
law may differ substantially from the corresponding federal law, and this
discussion does not purport to describe any aspect of the tax laws other than
federal income tax law. Therefore, potential investors should consult their tax
advisors with respect to the state, local and other tax consequences to them
arising from an investment in the Certificates.
 
ERISA CONSIDERATIONS
 
     The following describes certain considerations under the Employee
Retirement Income Act of 1974, as amended ("ERISA"), and the Code, which apply
only to Certificates of a Series that are not divided into subclasses. If
Certificates are divided into subclasses, the related Prospectus Supplement will
contain information concerning considerations relating to ERISA and the Code
that are applicable to such Certificates.
 
     Title I of ERISA imposes certain requirements on certain employee benefit
plans and arrangements, and upon collective investment funds and separate
accounts in which such plans or arrangements are invested, and on those persons
who are fiduciaries with respect to such benefit plans. Generally, Title I of
ERISA governs investments made by ERISA-covered employee benefit plans. Among
other things, ERISA requires that the assets of such plans be held in trust and
that the trustee, or other duly authorized fiduciary, have exclusive authority
and discretion to manage and control the assets of such plans. Title I of ERISA
also imposes certain duties on persons who are fiduciaries of ERISA-covered
plans. Under ERISA, any person who exercises any authority or control respecting
the management or disposition of the assets of an ERISA-covered plan is
considered to be a fiduciary of such Plan (subject to certain exceptions not
here relevant).
 
     In addition, benefit plans subject to Title I of ERISA and individual
retirement accounts or certain types of Keogh plans not subject to Title I of
ERISA but subject to Code Section 4975 (each a "Plan") are prohibited from
engaging in a broad range of transactions relating to the assets of the Plan
when persons having certain specified relationships to a Plan (called "parties
in interest" in ERISA and "disqualified persons" in the Code) are involved. Such
transactions are treated as "prohibited transactions" under ERISA Sections 406
and/or 407, and excise taxes are imposed upon such persons by Code Section 4975.
 
     Certain employee benefit plans, such as governmental plans (as defined in
ERISA Section 3(32)) and, if no election has been made under Section 410(d) of
the Code, church plans (as defined in ERISA Section 3(33)), are not subject to
Title I of ERISA or Code Section 4975. Accordingly, assets of such plans may be
invested in Certificates without regard to the ERISA considerations described
above and below,
                                       81
<PAGE>   200
 
subject to the provisions of applicable state law. Any such plan which is
qualified and exempt from taxation under Code Sections 401(a) and 501(a),
however, is subject to the prohibited transaction rules set forth in Code
Section 503.
 
     On November 13, 1986, the United States Department of Labor ("Labor")
issued final regulations (29 C.F.R. Section 2510.3-101) concerning the
definition of the assets of a Plan (the "Plan Asset Regulations"). Under the
Plan Asset Regulations, the underlying assets and properties of corporations,
partnerships, trusts and certain other entities in which a Plan makes an
"equity" investment (as opposed to a "debt" investment) will be deemed for
purposes of ERISA to be assets of the investing Plan unless, among other
exceptions, the equity participation by Plan investors in the equity investment
is not "significant." Under the Plan Asset Regulations, equity participation by
benefit plan investors is "significant" on any date if, immediately after the
most recent acquisition of the equity interest, 25% or more of the value of any
class of equity interests in the entity is held by retirement plans, including
Plans and plans not subject to ERISA (such as governmental and church plans).
Under the Plan Asset Regulations, an "equity" investment is an investment in an
entity other than an investment treated as indebtedness under applicable local
law and which has no substantial equity features. The beneficial interest in a
trust, the undivided ownership interest in property and the profit interest in a
partnership are deemed to be equity investments for this purpose.
 
     If an investing Plan's assets were deemed (under the Plan Asset Regulations
or other authority) to include an interest in the Mortgage Loans and any other
assets of the Trust, and not merely an interest in the Certificates, the assets
of the Trust would become subject to the fiduciary standards of ERISA, and
transactions with the Trust by certain parties dealing with the Trust might
constitute prohibited transactions, unless an exemption applies. Certain
exemptions which may be applicable to the acquisition and holding of the
Certificates or to the servicing of the Mortgage Loans are noted below.
 
     Regardless of whether the Mortgage Loans and any other assets of the Trust
would be considered "plan assets" for purposes of ERISA, the acquisition or
holding of Certificates on behalf of a Plan still could be considered to give
rise to a prohibited transaction if the Trust is or becomes a party in interest
or disqualified person with respect to such Plan, or if a subsequent transfer of
Certificates is made between a Plan and such party in interest or disqualified
person, unless an exemption otherwise applies. Exemptions which may be
applicable to such transactions are noted below.
 
PTCE 83-1
 
     In Prohibited Transaction Class Exemption 83-1 ("PTCE 83-1"), which amended
and Prohibited Transaction Class Exemption 81-7, Labor exempted from ERISA's
prohibited transaction rules and the excise tax provisions of Code Section 4975
certain transactions relating to the operation of residential mortgage pool
investment trusts and the purchase, sale and holding of "mortgage pool
pass-through certificates" in the initial issuance of such certificates. PTCE
83-1 permits, subject to certain conditions, transactions that might otherwise
be prohibited between Plans and parties in interest/disqualified persons with
respect to those Plans related to (i) the origination, maintenance and
termination of mortgage pools consisting solely of interest bearing obligations
secured by first or second mortgages or deeds of trust on single-family
residential property (non-farm property comprising one to four dwelling units,
including condominiums), property which had secured such obligations and was
acquired in foreclosure and undistributed cash, and (ii) the acquisition and
holding by Plans of certain mortgage pool pass-through certificates representing
beneficial undivided interests in such mortgage pools which entitle the holders
to pass-through payments of principal and interest from the underlying
obligations of the pool.
 
     If the general conditions (discussed below) of PTCE 83-1 are satisfied,
PTCE 83-1 will exempt from the prohibitions of ERISA Sections 406(a) and 407 and
the excise taxes imposed by Code Section 4975 by reason of Code Section
4975(a)(1)(A) through (D) (relating generally to transactions with parties in
interest/ disqualified persons who are not fiduciaries) the direct or indirect
sale, exchange or transfer in the initial issuance, and the continued holding,
by a Plan of Certificates that represent interests in a Mortgage Pool consisting
of Mortgage Loans representing loans for single family homes ("Single Family
Certificates") if the Plan purchases the Single Family Certificates at no more
than fair market value.
 
                                       82
<PAGE>   201
 
     In addition, if the general conditions (discussed below) of PTCE 83-1 are
satisfied, PTCE 83-1 will exempt from the prohibitions of ERISA Sections
406(b)(1) and (2) and the excise taxes imposed by Code Section 4975 by reason of
Code Section 4975(a)(1)(E) (relating generally to transactions with fiduciaries)
the direct or indirect sale, exchange or transfer in the initial issuance, and
the continued holding, by a Plan of Single Family Certificates if the sale,
exchange or transfer is expressly approved by a fiduciary independent of the
pool sponsor, trustee or insurer who has authority to manage and control those
plan assets being invested in the Single Family Certificates, the Plan pays no
more for the Single Family Certificates than would be paid in an arm's length
transaction with an unrelated party, no investment management, advisory or
underwriting fee or sales commission or similar compensation is paid to the pool
sponsor in connection with such sale, exchange or transfer, the Plan does not
purchase more than 25% of the value all Single Family Certificates, and at least
50% of all Single Family Certificates is purchased by persons independent of the
pool sponsor, trustee or insurer.
 
     If the general conditions (described below) of PTCE 83-1 are satisfied,
PTCE 83-1 will exempt from the prohibitions of ERISA Sections 406(a) and (b) and
the excise taxes imposed by Code Section 4975 by reason of Code Section 4975(c),
transactions in connection with the servicing and operation of a mortgage pool
described above if such transactions are carried out in accordance with the
terms of a binding pooling and servicing agreement which is made available to
investors before they purchase certificates issued by the pool.
 
     PTCE 83-1 does not provide an exemption for transactions involving
Subordinate Certificates. Accordingly, unless otherwise provided in the related
Prospectus Supplement, no transfer of a Subordinate Certificate may be made to a
Plan.
 
     The discussion in this and the next succeeding paragraph applies only to
Single Family Certificates. The Depositor believes that, for purposes of PTCE
83-1, the term "mortgage pass-through certificate" would include: (i)
Certificates issued in a Series consisting of only a single class of
Certificates; and (ii) Offered Certificates issued in a Series in which there is
only one class of Offered Certificates; provided that the Certificates in the
case of clause (i), or the Offered Certificates in the case of clause (ii),
evidence the beneficial ownership of both a specified percentage of future
interest payments (greater than 0%) and a specified percentage (greater than 0%)
of future principal payments on the Mortgage Loans. It is not clear whether a
class of Certificates that evidences the beneficial ownership in a Trust Fund
divided into Mortgage Loan Groups, beneficial ownership of a specified
percentage of interest payments only or principal payments only, or a notional
amount of either principal or interest payments, or a class of Certificates
entitled to receive payments of interest and principal on the Mortgage Loans
only after payments to other classes or after the occurrence of certain
specified events would be a "mortgage pass-through certificate" for purposes of
PTCE 83-1.
 
     PTCE 83-1 sets forth three general conditions which must be satisfied for
any transaction to be eligible for exemption: (i) the maintenance of a system of
insurance or other protection for the pooled mortgage loans and property
securing such loans, and for indemnifying Certificateholders (other than holders
of the Class R Certificates) against reductions in pass-through payments due to
property damage or defaults in loan payments in an amount not less than the
greater of one percent of the aggregate principal balance of all covered pooled
mortgage loans, or of the principal balance of the largest covered pooled
mortgage loan; (ii) the existence of a pool trustee who is not an affiliate of
the pool sponsor (provided that the trustee shall not be considered to be an
affiliate of the pool sponsor solely because the trustee has succeeded to the
rights and responsibilities of the pool sponsor pursuant to the terms of the
pooling and servicing agreement providing for such succession upon the
occurrence of one or more events of default by the pool sponsor); and (iii) a
limitation on the sum of all payments made to and retained by the pool sponsor
in connection with a mortgage pool, together with other funds inuring to its
benefit for administering the mortgage pool, to not more than adequate
consideration for selling the mortgage loans plus reasonable compensation for
services provided by the pool sponsor to the pool.
 
     The Depositor believes that the first general condition referred to above
will be satisfied with respect to the Certificates in a Series issued without a
subordination feature, or the Senior Certificates only in a Series issued with a
subordination feature, provided that the subordination and Reserve Fund,
subordination by
 
                                       83
<PAGE>   202
 
shifting of interests, the pool insurance or other form of credit enhancement
described herein (such subordination, pool insurance or other form of credit
enhancement being the system of insurance or other protection referred to above)
with respect to a Series of Certificates is maintained in an amount not less
than the greater of one percent of the aggregate principal balance of the
Mortgage Loans or the principal balance of the largest Mortgage Loan. See
"Description of the Certificates" herein. In the absence of a ruling that the
system of insurance or other protection with respect to a Series of Certificates
satisfies the first general condition referred to above, there can be no
assurance that these features will be so viewed by Labor. The Trustee will not
be affiliated with the Depositor.
 
     Each Plan fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold Single Family Certificates
must make its own determination as to whether the first and third general
conditions, and the specific conditions described briefly in the preceding
paragraph, of PTCE 83-1 have been satisfied, or as to the availability of any
other prohibited transaction exemptions. Each Plan fiduciary should also
determine whether, under the general fiduciary standards of investment prudence
and diversification, an investment in the 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.
 
UNDERWRITER EXEMPTIONS
 
     Labor has issued to various underwriters substantially similar individual
exemptions (each, an "Underwriter Exemption" and collectively, the "Underwriter
Exemptions") which apply to certain sales and servicing of "certificates" that
are obligations of a "trust" with respect to which such an underwriter is the
underwriter, manager or co-manager of an underwriting syndicate. The Underwriter
Exemptions provide relief which is generally similar to that provided by PTCE
83-1, but is broader in several respects.
 
     The Underwriter Exemptions contain several requirements, some of which
differ from those of PTCE 83-1. The Underwriter Exemptions contain an expanded
definition of "certificate," which includes an interest which entitles the
Certificateholder to pass-through payments of principal, interest and/or other
payments. The Underwriter Exemptions contain an expanded definition of "trust,"
which permits the trust corpus to consist of secured consumer receivables,
including obligations secured by shares issued by a cooperative housing
association. The definition of "trust," however, does not include private
mortgage-backed securities like the Private Mortgage-Backed Securities, and does
not include any other investment pool unless, inter alia: (i) the investment
pool consists only of assets of the type which have been included in other
investment pools; (ii) certificates evidencing interests in such other
investment pools have been purchased by investors other than Plans for at least
one year prior to the Plan's acquisition of certificates pursuant to the
Underwriter Exemptions; and (iii) certificates in such other investment pools
have been rated in one of the three highest generic rating categories of the
four credit rating agencies noted below.
 
     Generally, the Underwriter Exemptions require (i) that the acquisition of
certificates by a Plan must be on terms (including the price for the
certificates) that are at least as favorable to the Plan as they would be in an
arm's-length transaction with an unrelated party; (ii) that the rights and
interests evidenced by the certificates held by a Plan not be "subordinated" to
the rights and interests evidenced by other certificates of the same trust;
(iii) that certificates acquired by a Plan have received a rating at the time of
their acquisition that is in one of the three highest generic rating categories
of Standard and Poor's Ratings Services, Moody's Investors Service, Inc., Duff &
Phelps Inc. or Fitch Investors Service, Inc.; (iv) that the pool trustee must
not be an affiliate of the pool sponsor, nor an affiliate of the underwriter,
the pool servicer, any obligor with respect to mortgage loans included in the
trust constituting more than five percent of the aggregate unamortized principal
balance of the assets in the trust, or any affiliate of such entities; and (v)
that any Plan investing in the certificates must be an "accredited investor," as
defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange
Commission under the Securities Act of 1933.
 
     One or more other prohibited transaction exemptions may be available to a
Plan investing in Certificates, depending in part upon the type of Plan
fiduciary making the decision to acquire the Certificates and the circumstances
under which such decision is made, including but not limited to: (i) Prohibited
Transaction Class Exemption ("PTCE") 84-14, relating to investments effectuated
by "qualified professional asset
 
                                       84
<PAGE>   203
 
managers;" (ii) PTCE 90-1, relating to investments by insurance company pooled
separate accounts; (iii) PTCE 91-38, relating to investments by bank collective
investment funds; (iv) PTCE 95-60, relating to investments by insurance company
general accounts; and (v) PTCE 96-23, relating to investments effectuated by
"in-house asset managers."
 
     Any Plan fiduciary which proposes to cause a Plan to purchase Certificates
should consult with its counsel concerning the impact of ERISA and the Code, the
applicability of PTCE 83-1, one or more Underwriter Exemptions or any other
exemptions from the prohibited transactions of ERISA and the Code, and the
potential consequences in its specific circumstances, prior to making such
investment. The Prospectus Supplement for a Series of Certificates will contain
additional information with respect to prohibited transaction exemptions that
may be applicable to such Series of Certificates. Moreover, each Plan fiduciary
should determine whether, under the general fiduciary standards of investment
prudence and diversification, an investment in the 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. See "ERISA Considerations"
in the Prospectus.
 
     Any Plan purchasing Certificates shall be deemed to have represented, by
virtue of such purchase, that such an investment is permitted under the
governing benefit plan instruments and is appropriate for the benefit plan in
view of its overall investment policy and the composition and diversification of
its portfolio and is consistent with the requirements of ERISA and the Code.
 
                                LEGAL INVESTMENT
 
     The Prospectus 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 persons, trusts,
corporations, partnerships, associations, business trusts and business entities
(including depository institutions, life insurance companies and pension funds)
created pursuant to or existing under the laws of the United States or of any
state (including the District of Columbia and Puerto Rico) whose authorized
investments are subject to state regulation to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any such entities. Under SMMEA, if a state enacts
legislation prior to October 4, 1991, specifically limiting the legal investment
authority of any such entities with respect to "mortgage related securities,"
the Certificates that qualify as mortgage related securities will constitute
legal investments for entities subject to such legislation only to the extent
provided therein. Approximately twenty-one states adopted such legislation prior
to the October 4, 1991, deadline. SMMEA provides, however, that in no event will
the enactment of any such legislation affect the validity of any contractual
commitment to purchase, hold or invest in Certificates that qualify as mortgage
related securities, or require the sale or other disposition of such
Certificates, so long as such contractual commitment was made or such
Certificates acquired prior to the enactment of such legislation.
 
     SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal in Certificates
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase Certificates for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
SS24 (Seventh), subject in each case to such regulations as the applicable
federal authority may prescribe. In this connection, federal credit unions
should review the National Credit Union Administration ("NCUA") Letter to Credit
Unions No. 96, as modified by Letter to Credit Unions No. 108, which includes
guidelines to assist federal credit unions in making investment decisions for
mortgage related securities, and the NCUA's regulation "Investment and Deposit
Activities" (12 C.F.R. Part 703), (whether or not the Class of Certificates
under consideration for purchase constitutes a "mortgage related security").
 
     All depository institutions considering an investment in the Certificates
(whether or not the Class of Certificates under consideration for purchase
constitutes a mortgage related security should review the Federal
                                       85
<PAGE>   204
 
Financial Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
(the "Policy Statement"), setting forth, in relevant part, certain securities
trading and sales practices deemed unsuitable for an institution's investment
portfolio, and guidelines for (and restrictions on) investing in mortgage
derivative products, including mortgage related securities, which are "high-risk
mortgage securities" as defined in the Policy Statement. According to the Policy
Statement, such "high-risk mortgage securities" include securities such as
Certificates not entitled to distributions allocated to principal or interest,
or Subordinated Certificates. Under the Policy Statement, it is the
responsibility of each depository institution to determine, prior to purchase
(and at stated intervals thereafter), whether a particular mortgage derivative
product is a "high-risk mortgage security," and whether the purchase (or
retention) of such a product would be consistent with the Policy Statement.
 
     The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders, guidelines, or agreements generally
governing investments made by a particular investor, including, but not limited
to, "prudent investor" provisions, percentage-of-assets limits and provisions
that may restrict or prohibit investment in securities that are not "interest
bearing" or "income paying."
 
     There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase Certificates or to
purchase Certificates representing more than a specified percentage of the
investor's assets. Investors should consult their own legal advisors in
determining whether and to what extent the Certificates constitute legal
investments for such investors.
 
                             METHOD OF DISTRIBUTION
 
     The Certificates offered hereby and by the Prospectus Supplements will be
offered in Series. The distribution of the Certificates may be effected from
time to time in one or more transactions, including negotiated transactions, at
a fixed public offering price or at varying prices to be determined at the time
of sale or at the time of commitment therefor. If so specified in the related
Prospectus Supplement, the Certificates will be distributed in a firm commitment
underwriting, subject to the terms and conditions of the underwriting agreement,
by First Union Capital Markets Corp., an affiliate of the Depositor, acting as
underwriter with other underwriters, if any, named therein. In such event, the
Prospectus Supplement may also specify that the underwriters will not be
obligated to pay for any Certificates agreed to be purchased by purchasers
pursuant to purchase agreements acceptable to the Depositor. In connection with
the sale of the Certificates, underwriters may receive compensation from the
Depositor or from purchasers of the Certificates in the form of discounts,
concessions or commissions. The Prospectus Supplement will describe any such
compensation paid by the Depositor.
 
     Alternatively, the Prospectus Supplement may specify that the Certificates
will be distributed by First Union Capital Markets Corp. acting as agent or in
some cases as principal with respect to Certificates that it has previously
purchased or agreed to purchase. If First Union Capital Markets Corp. acts as
agent in the sale of Certificates, First Union Capital Markets Corp. will
receive a selling commission with respect to each Series of Certificates,
depending on market conditions, expressed as a percentage of the aggregate
principal balance of the Certificates sold hereunder as of the Cut-off Date. The
exact percentage for each Series of Certificates will be disclosed in the
related Prospectus Supplement. To the extent that First Union Capital Markets
Corp. elects to purchase Certificates as principal, First Union Capital Markets
Corp. may realize losses or profits based upon the difference between its
purchase price and the sales price. The Prospectus Supplement with respect to
any Series offered other than through underwriters will contain information
regarding the nature of such offering and any agreements to be entered into
between the Depositor and purchasers of Certificates of such Series.
 
     This Prospectus and the related Prospectus Supplement may be used by First
Union Capital Markets Corp., an affiliate of the Depositor, or any of its
affiliates in connection with offers and sales related to market-making
transactions in the Certificates. First Union Capital Markets Corp. may act as
principal or agent in such transactions. Such sales will be made at prices
related to prevailing market prices at the time of sale or otherwise.
 
                                       86
<PAGE>   205
 
     The Depositor will indemnify First Union Capital Markets Corp. and any
underwriters against certain civil liabilities, including liabilities under the
Securities Act of 1933, or will contribute to payments First Union Capital
Markets Corp. and any underwriters may be required to make in respect thereof.
 
     In the ordinary course of business, First Union Capital Markets Corp. and
the Depositor may engage in various securities and financing transactions,
including repurchase agreements to provide interim financing of the Depositor's
Mortgage Loans pending the sale of such Mortgage Loans or interests therein,
including the Certificates.
 
     The Depositor anticipates that the Certificates will be sold primarily to
institutional investors. Purchasers of Certificates, including dealers, may,
depending on the facts and circumstances of such purchases, be deemed to be
"underwriters" within the meaning of the Securities Act of 1933 in connection
with reoffers and sales by them of Certificates. Holders of Certificates should
consult with their legal advisors in this regard prior to any such reoffer or
sale.
 
     Underwriters or agents and their associates may be customers of (including
borrowers from), engage in transactions with and/or perform services for, FUNB,
its affiliates and the Trustee in the ordinary course of business.
 
                                 LEGAL MATTERS
 
     Unless otherwise specified in the related Prospectus Supplement, certain
legal matters relating to the Certificates, including certain federal income tax
consequences with respect thereto, will be passed upon for the Depositor by
Moore & Van Allen, PLLC.
 
                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Certificates
and no Trust Fund will engage in any business activities or have any assets or
obligations prior to the issuance of the related Series of Certificates.
Accordingly, no financial statements with respect to any Trust Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is a condition to the issuance of the Certificates of each Series
offered hereby and by the Prospectus Supplement that they shall have been rated
in one of the four highest rating categories by the nationally recognized
statistical rating agency or agencies specified in the related Prospectus
Supplement.
 
     Ratings on mortgage pass-through certificates address the likelihood of
receipt by certificateholders of all distributions on the underlying mortgage
loans. These ratings address the structural, legal and issuer-related aspects
associated with such certificates, the nature of the underlying mortgage loans
and the credit quality of the credit enhancer or guarantor, if any. Ratings on
mortgage pass-through certificates do not represent any assessment of the
likelihood of principal prepayments by mortgagors or of the degree by which such
prepayments might differ from those originally anticipated. As a result,
certificateholders might suffer a lower than anticipated yield, and, in
addition, holders of stripped pass-through certificates in extreme cases might
fail to recoup their underlying investments.
 
     A security rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
organization. Each security rating should be evaluated independently of any
other security rating.

                                    ANNEX I
                        GLOBAL CLEARANCE, SETTLEMENT AND
                          TAX DOCUMENTATION PROCEDURES
 
     Except in certain limited circumstances, a class of Book-Entry Certificates
(the "Global Securities") will be available only in book-entry form. Investors
in the Global Securities may hold such Global Securities through any of DTC,
CEDEL or Euroclear. The Global Securities will be tradeable as home market
instruments in both the European and U.S. domestic markets. Initial settlement
and all secondary trades will settle in same-day funds.
 
     Secondary market trading between investors holding Global Securities
through CEDEL and Euroclear will be conducted in the ordinary way in accordance
with their normal rules and operating procedures and in accordance with
conventional eurobond practice (i.e., seven calendar day settlement).
 
     Secondary market trading between investors holding Global Securities
through DTC will be conducted according to the rules and procedures applicable
to U.S. corporate debt obligations and prior Residential Mortgage Pass-Through
Certificates issues.
 
     Secondary cross-market trading between CEDEL or Euroclear and DTC
Participants holding Certificates will be effected on a delivery-against-payment
basis through the respective Depositories of CEDEL and Euroclear (in such
capacity) and as DTC Participants.
 
     Non-U.S. Holders (as described below) of Global Securities will be subject
to U.S. withholding taxes unless such Holders meet certain requirements and
deliver appropriate U.S. tax documents to the securities clearing organizations
or their participants.
 
                               INITIAL SETTLEMENT
 
     All Global Securities will be held in book-entry form by DTC in the name of
Cede & Co. as nominee of DTC. Investors' interests in the Global Securities will
be represented through financial institutions acting on their behalf as direct
and indirect Participants in DTC. As a result, CEDEL and Euroclear will hold
positions on behalf of their Participants through their respective Depositories,
which in turn will hold such positions in accounts as DTC Participants.
 
     Investors electing to hold their Global Securities through DTC will follow
the settlement practices applicable to prior Residential Mortgage Pass-Through
Certificates issues. Investor securities custody accounts will be credited with
their holdings against payment in same-day funds on the settlement date.
 
     Investors electing to hold their Global Securities through CEDEL or
Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" or restricted period. Global Securities will be credited to the
securities custody accounts on the settlement date against payment in same-day
funds.
 
                            SECONDARY MARKET TRADING
 
     Since the purchaser determines the place of delivery, it is important to
establish at the time of the trade where both the purchaser's and seller's
accounts are located to ensure that settlement can be made on the desired value
date.
 
     Trading Between DTC Participants.  Secondary market trading between DTC
Participants will be settled using the procedures applicable to prior
Residential Mortgage Pass-Through Certificates issues in same-day funds.
 
     Trading Between Cedel and/or Euroclear Participants.  Secondary market
trading between CEDEL Participants or Euroclear Participants will be settled
using the procedures applicable to conventional eurobonds in same-day funds.
 
                                       A-1
<PAGE>   207
 
     Trading Between DTC Seller and CEDEL or Euroclear Purchaser. When Global
Securities are to be transferred from the account of a DTC Participant to the
account of a CEDEL Participant or a Euroclear Participant, the purchaser will
send instructions to CEDEL or Euroclear through a CEDEL Participant or Euroclear
Participant at least one business day prior to settlement. CEDEL or Euroclear
will instruct the respective Depository, as the case may be, to receive the
Global Securities against payment. Payment will include interest accrued on the
Global Securities from and including the last coupon payment date to and
excluding the settlement date, on the basis of the actual number of days in such
accrual period and a year assumed to consist of 360 days. For transactions
settling on the 31st of the month, payment will include interest accrued to and
excluding the first day of the following month. Payment will then be made by the
respective Depository of the DTC Participant's account against delivery of the
Global Securities. After settlement has been completed, the Global Securities
will be credited to the respective clearing system and by the clearing system,
in accordance with its usual procedures, to the CEDEL Participant's or Euroclear
Participant's account. The securities credit will appear the next day (European
time) and the cash debt will be back-valued to, and the interest on the Global
Securities will accrue from, the value date (which would be the preceding day
when settlement occurred in New York). If settlement is not completed on the
intended value date (i.e., the trade fails), the CEDEL or Euroclear cash debt
will be valued instead as of the actual settlement date.
 
     CEDEL Participants and Euroclear Participants will need to make available
to the respective clearing systems the funds necessary to process same-day funds
settlement. The most direct means of doing so is to preposition funds for
settlement, either from cash on hand or existing lines of credit, as they would
for any settlement occurring within CEDEL or Euroclear. Under this approach,
they may take on credit exposure to CEDEL or Euroclear until the Global
Securities are credited to their accounts one day later.
 
     As an alternative, if CEDEL or Euroclear has extended a line of credit to
them, CEDEL Participants or Euroclear Participants can elect not to preposition
funds and allow that credit line to be drawn upon the finance settlement. Under
this procedure, CEDEL Participants or Euroclear Participants purchasing Global
Securities would incur overdraft charges for one day, assuming they cleared the
overdraft when the Global Securities were credited to their accounts. However,
interest on the Global Securities would accrue from the value date. Therefore,
in many cases the investment income on the Global Securities earned during that
one-day period may substantially reduce or offset the amount of such overdraft
charges, although this result will depend on each CEDEL Participant's or
Euroclear Participant's particular cost of funds.
 
     Since the settlement is taking place during New York business hours, DTC
Participants can employ their usual procedures for sending Global Securities to
the respective European Depository for the benefit of CEDEL Participants or
Euroclear Participants. The sale proceeds will be available to the DTC seller on
the settlement date. Thus, to the DTC Participants a cross-market transaction
will settle no differently than a trade between two DTC Participants.
 
     Trading Between CEDEL or Euroclear Seller and DTC Purchaser. Due to time
zone differences in their favor, CEDEL Participants and Euroclear Participants
may employ their customary procedures for transactions in which Global
Securities are to be transferred by the respective clearing system, through the
respective Depository, to a DTC Participant. The seller will send instructions
to CEDEL or Euroclear through a CEDEL Participant or Euroclear Participant at
least one business day prior to settlement. In these cases CEDEL or Euroclear
will instruct the respective Depository, as appropriate, to deliver the Global
Securities to the DTC Participant's account against payment. Payment will
include interest accrued on the Global Securities from and including the last
coupon payment to and excluding the settlement date on the basis of the actual
number of days in such accrual period and a year assumed to consist of 360 days.
For transactions settling on the 31st of the month, payment will include
interest accrued to and excluding the first day of the following month. The
payment will then be reflected in the account of the CEDEL Participant or
Euroclear Participant the following day, and receipt of the cash proceeds in the
CEDEL Participant's or Euroclear Participant's account will be back-valued to
the value date (which would be the preceding day, when settlement occurred in
New York). Should the CEDEL Participant or Euroclear Participant have a line of
credit with its respective clearing system and elect to be in debt in
anticipation of receipt of the sale proceeds in its account, the back-valuation
will extinguish any overdraft incurred over that one-day period. If settlement
                                       A-2
<PAGE>   208
 
is not completed on the intended value date (i.e., the trade fails), receipt of
the cash proceeds in the CEDEL Participant's or Euroclear Participant's account
would instead be valued as of the actual settlement date.
 
     Finally, day traders that use CEDEL or Euroclear and that purchase Global
Securities from DTC Participants for delivery to CEDEL Participants or Euroclear
Participants should note that these trades would automatically fail on the sale
side unless affirmative action were taken. At least three techniques should be
readily available to eliminate this potential problem:
 
          (a) borrowing through CEDEL or Euroclear for one day (until the
     purchase side of the day trade is reflected in their CEDEL or Euroclear
     accounts) in accordance with the clearing system's customary procedures;
 
          (b) borrowing the Global Securities in the U.S. from a DTC Participant
     no later than one day prior to settlement, which would give the Global
     Securities sufficient time to be reflected in their CEDEL or Euroclear
     account in order to settle the sale side of the trade; or
 
          (c) staggering the value dates for the buy and sell sides of the trade
     so that the value date for the purchase from the DTC Participant is at
     least one day prior to the value date for the sale to the CEDEL Participant
     or Euroclear Participant.
 
           CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS
 
     A beneficial owner of Global Securities holding securities through CEDEL or
Euroclear (or through DTC if the Holder has an address outside the U.S.) will be
subject to the 30% U.S. withholding tax that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons, unless (i) each clearing system, bank or other financial institution
that holds customers' securities in the ordinary course of its trade or business
in the chain of intermediaries between such beneficial owner and the U.S. entity
required to withhold tax complies with applicable certification requirements and
(ii) such beneficial owner takes one of the following steps to obtain an
exemption or reduced tax rate:
 
          Exemption for Non-U.S. Persons (Form W-8).  Beneficial owners of
     Global Securities that are non-U.S. Persons can obtain a complete exemption
     from the withholding tax by filing a signed Form W-8 (Certificate of
     Foreign Status). If the information shown on Form W-8 changes, a new Form
     W-8 must be filed within 30 days of such change.
 
          Exemption for Non-U.S. Persons with Actively Connected Income (Form
     4224).  A non-U.S. Person, including a non-U.S. corporation or bank with a
     U.S. branch, for which the interest income is effectively connected with
     its conduct of a trade or business in the United States, can obtain an
     exemption from the withholding tax by filing Form 4224 (Exemption from
     Withholding of Tax on Income Effectively Connected with the Conduct of a
     Trade or Business in the United States).
 
          Exemption or Reduced Rate for Non-U.S. Persons Resident in Treaty
     Countries (Form 1001). Non-U.S. Persons that are Certificate Owners
     residing in a country that has a tax treaty with the United States can
     obtain an exemption or reduced tax rate (depending on the treaty terms) by
     filing Form 1001 (Ownership, Exemption or Reduced Rate Certificate). If the
     treaty provides only for a reduced rate, withholding tax will be imposed at
     that rate unless the filer alternatively files Form W-8. Form 1001 may be
     filed by the Certificate Owners or his agent.
 
          Exemption for U.S. Persons (Form W-9).  U.S. Persons can obtain a
     complete exemption from the withholding tax by filing Form W-9 (Payer's
     Request for Taxpayer Identification Number and Certification).
 
          U.S. Federal Income Tax Reporting Procedure.  The Certificate Owner of
     a Global Security or, in the case of a Form 1001 or a Form 4224 filer, his
     agent, files by submitting the appropriate form to the person through whom
     it holds (the clearing agency, in the case of persons holding directly on
     the books of the clearing agency). Form W-8 and Form 1001 are effective for
     three calendar years and Form 4224 is effective for one calendar year.
 
                                       A-3
<PAGE>   209
 
     The term "U.S. Person" means (i) a citizen or resident of the United
States, (ii) a corporation or partnership organized in or under the laws of the
United States or any political subdivision thereof or (iii) an estate or trust
the income of which is includable in gross income for United States tax
purposes, regardless of its source. This summary does not deal with all aspects
of U.S. Federal income tax withholding that may be relevant to foreign holders
of the Global Securities. Investors are advised to consult their own tax
advisors for specific tax advice concerning their holding and disposing of the
Global Securities.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Pooling and Servicing Agreements will provide that no director,
officer, employee or agent of the Registrant is liable to the Trust Fund or the
Certificateholders, except for any liability that would otherwise be imposed by
reason of misfeasance, bad faith or negligence in the performance of duties
under such Pooling and Servicing Agreements, or by reason of reckless disregard
of such duties. The Pooling and Servicing Agreements will further provide that,
with the exceptions stated above, a director, officer, employee or agent of the
Registrant is entitled to be indemnified and held harmless by the Trust Fund
against any loss, liability or expense incurred in connection with legal action
relating to such Pooling and Servicing Agreements and related Certificates,
other than any loss, liability or expense: (i) specifically required to be borne
thereby pursuant to the terms of such Pooling and Servicing Agreements, or
otherwise incidental to the performance of obligations and duties thereunder and
(ii) incurred in connection with any violation of any state or federal
securities law.
 
     Sections 55-8-50 through 55-8-58 of the revised North Carolina Business
Corporation Act (the "NCBCA") contained specific provisions relating to
indemnification of directors and officers of North Carolina corporations. In
general, the statute provides that (i) a corporation must indemnify a director
or officer for reasonable expenses incurred in relation to the proceeding who is
wholly successful in defense of a proceeding to which he is a party because of
his status as such, unless limited by the articles of incorporation, and (ii) a
corporation may indemnify a director or officer if he is not wholly successful
in such defense, if it is determined as provided in the statute that the
director or officer meets a certain standard of conduct; provided, when a
director or officer is liable to the corporation or was found liable in a
proceeding changing improper benefit to him, the corporation may not indemnify
him. The statute also permits a director or officer of a corporation who is a
party to a proceeding to apply to the courts for indemnification, unless the
articles of incorporation provide otherwise, and the court may order
indemnification under certain circumstances set forth in the statute. The
statute further provides that a corporation may, in its articles of
incorporation, by contract or by resolution, provide indemnification in addition
to that provided by the statute, subject to certain conditions set forth in the
statute.
 
     The Registrant maintains directors and officers liability insurance, which
provides coverage up to $80,000,000, subject to certain deductible amounts. In
general, the policy insures (i) the Registrant's directors and its officers
against certain losses and/or (ii) the Registrant against loss arising from
claims against the directors and officers by reason of their wrongful acts, all
subject to the terms and conditions contained in the policy.
 
                                      II-1
<PAGE>   216
 
     Under agreements that may be entered into by the Registrant, certain
controlling persons, directors and officers of the Registrant may be entitled to
indemnification by underwriters and agents who participate in the distribution
of Certificates covered by the Registration Statement against certain
liabilities, including liabilities under the Securities Act.

   Registration Statement No. 333-3574 and incorporated herein by reference.
** To be filed by amendment.
 
ITEM 17.  UNDERTAKINGS
 
     A. UNDERTAKINGS PURSUANT TO RULE 415
 
     The Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act,
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in the volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of the prospectus
        filed with the Commission pursuant to Rule 424(b) if, in the aggregate,
        the changes in volume and price represent no more than a 20% change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change of such information in the Registration
        Statement; provided, however, paragraphs (A)(1)(i) and (A)(1)(ii) of
        this Item 17 do not apply if the Registration Statement is on Form S-3
        and the information required to be
 
                                      II-2
<PAGE>   217
 
        included in a post-effective amendment by those paragraphs is contained
        in periodic reports filed with or furnished to the Commission by the
        Registrant pursuant to Section 13 or Section 15(d) of the Securities
        Exchange Act of 1934 that are incorporated by reference in this
        Registration Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     B. FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE
 
     The Registration hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be the initial bona fide offering
thereof.
 
     C. UNDERTAKING IN RESPECT OF INDEMNIFICATION
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

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

Statement to be signed on its behalf by the undersigned, thereunto duly

for cancellation of the certificate for such shares with proper endorsement on
the certificate or on a separate accompanying document together with such
evidence of the payment of transfer taxes and compliance with such other
provisions of law as the corporation or its transfer agent may require.

         Section 3. Lost certificate. The Board of Directors may direct a new
certificate to be issued in place of any certificate theretofore issued by the
corporation claimed to have been lost or destroyed, upon receipt of an affidavit
of such fact from the person claiming the certificate of stock to have been lost
or destroyed. When authorizing such issue of a new certificate, the Board of
Directors shall require that the owner of such lost or destroyed certificate, or
his legal representative, give the corporation a bond in such sum as the Board
may direct as indemnity against any claim that may be made against the
corporation with respect to the certificate claimed to have been lost or
destroyed, except where the Board of Directors by resolution finds that in the
judgment of the directors the circumstances justify omission of a bond.

         Section 4. Closing transfer books and fixing record date. For the
purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or entitled to receive
payment of any dividend, or in order to make a determination of shareholders
for any other proper purpose, the Board of Directors may provide that the stock
transfer books shall be closed for a stated period but not to exceed, in any
case, fifty days. If the stock transfer books shall be closed for the purpose of
determining shareholders entitled to notice of or to vote at a meeting of
shareholders, such books shall be closed for at least ten days immediately
preceding such meeting.

         In lieu of closing the stock transfer books, the Board of Directors may
fix in advance a date as the record date for any such determination of
shareholders, such record date in any case to be not more than fifty days, and
in case of a meeting of shareholders, not less than ten days, immediately
preceding the date on which the particular action, requiring such
determination of shareholders is to be taken.

         If the stock transfer books are not closed and no record date is fixed
for the determination of shareholders entitled to notice of or to vote at a
meeting of shareholders, or shareholders entitled to receive payment of a
dividend, the date on which notice of the meeting is mailed or the date on which
the resolution of the Board of Directors declaring such dividend is adopted, as
the case may be, shall be the record date for such determination of
shareholders.

         When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this section, such determination shall
apply to any adjournment thereof, except where the determination has been made
through the closing of the stock transfer books and the stated period of closing
has expired.

just as if that person had full competency, capacity and authority to exercise
all rights of ownership irrespective of any knowledge or notice to the contrary
or any description indicating a representative, pledge or other fiduciary
relation or any reference to any other instrument or to the rights of any other
person appearing upon its record or upon the share certificate except that any

given to any shareholder or director by law, by the charter or by these by-laws,

notice, whether before or after the time stated therein, shall be equivalent to
the giving of such notice.

         Section 4. Fiscal Year. The fiscal year of the corporation shall be
fixed by the Board of Directors, and in the absence of any action on the matter,
the fiscal year shall be the calendar year.

by-laws may be amended or repealed and new bylaws may be adopted by the
affirmative vote of a majority of the directors then holding office at any
regular or special meeting of the Board of Directors.
